Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a high-pressure hydraulic pipe support device for the Matir coal mine. Background Technology

[0002] In coal mining, the mast is a key piece of equipment connecting the transfer machine and the conveyor belt in the longwall mining face. Due to the long suspension distance of the conveyor belt at the connection point between the mast and the belt, the idlers on the mast bear a heavy load and are prone to damage, thus requiring frequent replacement. To improve work efficiency and eliminate safety hazards during idler replacement, the conventional practice is to weld two hydraulic cylinders with hydraulic locks to the left and right sides of the front support frame of the mast to ensure that personal injury accidents caused by self-unloading after the cylinders are raised are not possible. However, the traditional support structure for coal mine masts has the following problems in practical applications:

[0003] At the Matil support structure, the bottom of the cable liquid pipe trough end is supported by only a single unit without effective secondary protection. This cannot guarantee the stability of the cable liquid pipe trough support and could seriously lead to the cable liquid pipe trough becoming unstable and falling, which would endanger the lives of personnel in the mine. Secondly, the single anti-tipping rope is fixed to the cable pipeline distance chain and cannot effectively prevent tipping. Utility Model Content

[0004] The purpose of this utility model is to provide a high-pressure liquid pipe support device at the Matir section of a coal mine, in order to solve the problems mentioned in the background art regarding the support structure at the Matir section. Firstly, the bottom of the cable liquid pipe trough end is supported by only a single unit without effective secondary protection, which cannot guarantee the stability of the cable liquid pipe trough support. This could lead to the cable liquid pipe trough becoming unstable and falling, posing a life-threatening risk to personnel in the mine. Secondly, the single anti-tipping rope is fixed to the cable pipeline distance chain, which cannot effectively prevent tipping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure hydraulic pipe support device for the mate in a coal mine, comprising a mate support rod, a fixing device for support installation fixedly connected to the bottom of the mate support rod, a hydraulic assembly for auxiliary support fixedly connected to the bottom of the fixing device, an installation plate fixedly connected to the telescopic end of the hydraulic assembly, a support base rod fixedly connected to the bottom of the installation plate, and a moving device fixedly connected to the bottom of the support base rod. The addition of the high-pressure hydraulic pipe support device solves the collapse problem, ensures worker safety, and protects the mate installation.

[0006] Preferably, the hydraulic assembly includes a supporting hydraulic cylinder. A first hydraulic hole is fixedly connected to the top of one side of the supporting hydraulic cylinder, and an outlet pipe is fixedly connected to one side of the first hydraulic hole. A second hydraulic hole is fixedly connected to the bottom of one side of the supporting hydraulic cylinder, and a suction pipe is fixedly connected to the top of the second hydraulic hole. A fixing ring is fixedly installed in the middle of the supporting hydraulic cylinder. The hydraulic device can provide a large supporting force, and the supporting height of the device can be precisely adjusted. The hydraulic rod inside the supporting hydraulic cylinder passes through the mounting plate and is fixedly connected to the inner wall of the supporting base rod. By controlling the flow and pressure of the hydraulic oil, the supporting device can be slowly raised or lowered with millimeter-level precision, allowing multiple hydraulic devices to be synchronized in height. When subjected to external impact, the hydraulic oil can play a buffering role within the system, and it is adaptable to various occasions.

[0007] Preferably, the fixing device includes a connecting pile, the top of which is snapped into a fixing member, and the top of the fixing member is fixedly connected to a fixing column. After the snap-fit ​​connection, it is fixed by bolts. When maintenance, repair, or replacement of the device is required, the bolt connection is very convenient; disassembly is achieved by tightening the bolts on both sides. The installation is also highly stable and cost-effective, preventing it from falling due to its own weight or slight external vibrations. Because the bolts, when tightened, generate sufficient friction between the fixing member and the device, firmly fixing the device in its position and providing a solid foundation for stable operation or placement.

[0008] Preferably, the fastener is U-shaped, and a fixing pin is threaded to one side of the fastener. Pin holes are provided on the surface of both the fastener and the connecting pile.

[0009] Preferably, the moving device includes a connecting plate, with protective covers fixedly connected to both sides of the connecting plate, connecting buckles fixedly connected to both ends of the two protective covers, and a central shaft fixedly connected between the two connecting buckles on the same side. Rollers are sleeved and connected to the surfaces of the two central shafts to facilitate the movement of the Mathilde position, reduce downtime caused by equipment handling, thereby improving the efficiency of equipment use, reducing the burden of manual handling, avoiding collisions and damage, and reducing the cost of equipment maintenance and replacement.

[0010] Preferably, the connecting plate is made of channel steel, which has high overall structural strength.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Hydraulic support allows for stable fixation to the ground via the extension and retraction of hydraulic rods. This stabilizes the cable conduit, facilitating the installation of moving devices, and prevents collapses caused by the cable conduit, ensuring the safety of coal miners and equipment while also improving coal mining efficiency.

[0013] The support device is fixed to the Mathil support rod by the top fixing device, which is stable and can prevent tipping. The overall structure has high strength and is safe and reliable. Attached Figure Description

[0022] In use, the fixing column 16 and the fixing part 17 are fixed to the top of the Mathil support rod 1 by welding. Then, the connecting pile 15 is inserted into the fixing part 17. The connecting pile 15 and the fixing part 17 are fixed on both sides with bolts to prevent them from falling. At this time, the top of the support device is fixed. The fixing part 17 is U-shaped, which makes it easy to snap the connecting pile 15 into place. It is easy to disassemble and can be reused, reducing costs.

[0023] See Figure 1 and Figure 3 The hydraulic assembly includes a supporting hydraulic cylinder 3, a first hydraulic hole 14 is fixedly connected to the top of one side of the supporting hydraulic cylinder 3, an outlet pipe 11 is fixedly connected to one side of the first hydraulic hole 14, a second hydraulic hole 12 is fixedly connected to the bottom of one side of the supporting hydraulic cylinder 3, a suction pipe 10 is fixedly connected to the top of the second hydraulic hole 12, and a fixing ring 18 is fixedly provided in the middle of the supporting hydraulic cylinder 3.

[0024] In use, an external hydraulic pump is used to pump hydraulic oil through the outlet pipe 11 and the suction pipe 10 to control the amount of hydraulic oil in the supporting hydraulic cylinder 3, thereby controlling the extension and retraction of the supporting hydraulic cylinder 3. Through the supporting base rod 4, the moving device 5 is pushed down to contact the ground and achieve support.

[0025] See Figure 1 and Figure 2 The mobile device 5 includes a connecting plate 8, with protective covers 19 fixedly connected to both sides of the connecting plate 8, and connecting buckles 6 fixedly connected to both ends of the two protective covers 19.
