Hydraulic Support System

Hydraulic Support System:

Hydraulic Support System is a specialised disassembly and meeting tools designed for hydraulic aid columns, jacks, and one of a form factors in coal mine entire mining. It adopts mechanical, hydraulic, and electrical machine linkage manage to reap environment first-rate and automatic operations. Its core shape includes:

1. Mobile base: geared up with taking walks wheels or tracks, it can be flexibly moved to the working surface, lowering gear transportation time.

2. Clamping sliding device: Fix the column with a hydraulic chuck or self positioning locking mechanism to adapt to workpieces of exclusive diameters (such as 200-650mm) and lengths (such as 2200mm).

3. Hydraulic motor transmission: It makes use of a low-speed excessive torque hydraulic motor to pressure rotation, with an preliminary torque of up to 9000N · m, making it straight ahead to disassemble corroded or threaded components.

4. Long stroke slide table: Equipped with a hydraulic slide desk with a stroke of 1800mm or more, it can entire a couple of techniques such as pulling out the active column and disassembling the records sleeve in one go.

5. Modular design: integrating practical gadgets such as three-way valve separation and base disassembly, assisting speedy mildew substitute to adapt to one-of-a-kind types of brackets.

Packaging and Shipping Standards:

1. Equipment fixation and protection

Independent packaging of core components: precision factors such as hydraulic motor and reducer shall be crammed with shockproof foam and strengthened with timber body to forestall seal harm or axial displacement due to collision for the duration of transportation. For example, the CZ-3.5 column dismantling energy station of Taian Warner has a motor strength of 18.5KW, and its motor wants to be one by one constant on a custom-made tray to keep away from direct contact with steel components.

Electrical gadget isolation: PLC manipulate cabinets, sensors and different electrical aspects want to be packaged in anti-static luggage and labeled with "fragile" symptoms to forestall quick circuits induced by way of moisture or static electricity.

Modular mildew classification storage: Three reason valve separation molds, base disassembly fixtures, etc. want to be categorised and packed in accordance to models, with meeting drawings connected to keep away from confusion on site.

2. Selection of packaging materials

Rust prevention treatment: After spraying rust prevention oil on the metallic floor of the equipment, wrap it with VCI vapor segment rust prevention movie and cowl it with water-resistant canvas. For example, the eccentric bidirectional chuck science dismantling computing device of Shandong Dongda Electromechanical requires the chuck to be covered with exclusive anti rust grease earlier than packaging to make certain that the transport surroundings does no longer rust.

Structural reinforcement: For lengthy stroke sliding tables (such as 1800mm and above), perspective metal welding is required to strengthen the frame, and the gear is constant to the backside plate with bolts. The CZ-3.5 column dismantling desktop from Tai'an Jiufang has a whole dimension of 5700 × 1530 × 840mm, and its backside plate desires to be welded with metal plates of 10mm or extra to forestall deformation all through transportation.

3. Transportation and loading/unloading standards

Vehicle matching: Select a heavy-duty flatbed truck with greater than 10 axles based totally on the weight of the gear (such as the complete weight of the Haozhou Mining column dismantling machine, which is about 5 tons), to make sure that the carriage is flat and free of protrusions.

Lifting operation: Use an aerial crane weighing over 50 heaps for lifting, and rubber sleeves ought to be introduced to the contact region between the sling and the equipment; When loading, the core of gravity of the gear must coincide with the automobile axis, with a deviation of no extra than 50mm.

Precautions for use:

1. Pre operation inspection

Component integrity: Check if the hydraulic pipeline connections are right and if all U-shaped playing cards are inserted; Add 30 # or forty six # equipment oil to the oil tank till it reaches 3/4 of the liquid degree transmitter.

Material adaptability: Select gorgeous fixtures primarily based on the pillar mannequin (such as DZ kind single hydraulic pillar).

Environmental safety: Clean up particles on website online to make certain spacious working space; Check the balance of the pinnacle plate and straight away restore any damaged nets or ropes found. For example, when dismantling hydraulic helps for giant mining heights, brief scaffolding guide wishes to be set up 300-500mm close to the subsequent body in the frame pit after every dismantling.

2. Standardization throughout operation

Torque control: Real time adjustment of velocity and torque (range 1000-210000N · m) thru hydraulic gadget to keep away from gear harm precipitated by using overload.

Forward and backward rotation: Implement ahead and backward rotation in accordance to the plan, and manipulate the pace in actual time to make the device extra reliable.

Personnel positioning: During operation, personnel have to stand at a secure distance to forestall the pillar from tipping over or the stay pillar from popping out and injuring people. For example, when disassembling the pinnacle cover, it is vital to use a stopper to preserve the pinnacle cover, function the center plate valve to make the column jack power the pulley to move, and personnel are strictly prohibited from attaining into the unsafe area.

3. Maintenance and upkeep

Regular lubrication: Add lithium based totally grease to shifting components such as information rails and sliders each and every five hundred hours to decrease frictional resistance.

Hydraulic oil replacement: Replace the hydraulic oil each 2000 hours and smooth the oil tank and filter screen. If the oil is located to have deteriorated or the cleanliness is no longer up to standard, it wants to be changed immediately, in any other case it will have an effect on the effectivity of the device operation.

Electrical device inspection: Regularly take a look at whether or not the wiring terminals of the electrical manipulate cupboard are unfastened to keep away from terrible contact and gear failure.

4. Safety safety measures

Emergency give up device: Install crimson emergency end buttons round the operation panel and tools to make sure that the electricity can be reduce off inside 0.5 seconds in case of emergencies (such as chuck slippage).

Protective fence setting: Install metallic guardrails with a peak of ≥ 1.2m in open areas (such as the sliding range) to forestall personnel from by chance coming into and inflicting compression injuries.

Overload protection: The hydraulic machine is geared up with an overflow valve, which routinely releases strain when the strain exceeds the set price (such as 25MPa) to stop tools damage.
