Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of movable column assembly equipment, and more specifically, to a movable column assembly equipment and an assembly method. Background Art

[0002] The movable column is a key component in a hydraulic support. The main function of the movable column is to provide support force for the hydraulic support. In the operation of a coal mine, it is often used to support the roof underground in the coal mine to prevent the roof from collapsing and ensure the safety of the working space. At the same time, the movable column can also flexibly adjust the height of the hydraulic support according to the actual situation of the coal mining face, so as to adapt to different coal seam thicknesses and ensure the smooth progress of coal mining work.

[0003] The movable column usually consists of a large cylinder, a middle cylinder, and related seals and guide sleeves. The large cylinder is the fixed part, usually installed on the base of the hydraulic support, while the middle cylinder is the telescopic part that can move up and down inside the large cylinder to achieve the lifting function of the hydraulic support.

[0004] During assembly, usually a crane is used to fixedly install the large cylinder on the clamping plate, and then the middle cylinder is placed above the large cylinder by the crane and moved down into it. When placing the middle cylinder into the large cylinder, due to the friction between the contact surfaces of the middle cylinder and the large cylinder, sufficient force is required to push it down. During installation, usually workers support the middle cylinder and manually press it down while the lifting chain of the crane drives the middle cylinder to move down into the large cylinder. And after threadedly installing the guide sleeve on the thread of the large cylinder, it is also manually rotated and connected by a worker holding a wrench. This assembly method has many manual operation processes, is relatively laborious and has low efficiency. Summary of the Invention

The connecting plate is fixedly connected to the output end of the first electric cylinder, and a sliding groove is formed at the bottom of the connecting plate. There are two mounting plates, and the two mounting plates are respectively fixedly installed on both sides of the connecting plate. The second electric cylinders are respectively installed on the sides of the two mounting plates. There are two hexagonal rods, and the two hexagonal rods are respectively fixedly connected to the output ends of the two second electric cylinders. The top of the hexagonal rod is slidably installed in the sliding groove at the bottom of the connecting plate through a slider.

[0009] Further, the clamping assembly includes a third electric cylinder, a forward clamping block, and a lateral fixing component. There are two third electric cylinders, and the two third electric cylinders are both installed at the top of the telescopic tongue. There are two forward clamping blocks, and the two forward clamping blocks are respectively fixedly connected to the output ends of the two third electric cylinders. There are two lateral fixing components, and the two lateral fixing components are respectively arranged on the sides of the two forward clamping blocks.

[0010] Further, the lateral fixing component includes a support plate, a fourth electric cylinder, and a lateral clamping block. The support plate is fixedly installed on the side of the forward clamping block, and the support plate is L-shaped. The fourth electric cylinder is installed on the side of the support plate. The lateral clamping block is fixedly connected to the output end of the fourth electric cylinder.

[0011] In order to place the large cylinder on the telescopic tongue for movement, further, a support frame is fixedly installed at the bottom end of the telescopic tongue, and a circular placement groove is provided at the center position of the top end of the support frame.

[0012] In order to be able to push the telescopic tongue and the flat push base to move on the base platform, furthermore, a flat push hydraulic cylinder is installed on the base platform, and both the telescopic tongue and the flat push base are fixedly connected to the output end of the flat push hydraulic cylinder on the base platform.

[0013] A method for assembling a movable pillar column uses a movable pillar column assembling device of the above scheme, including the following steps: Step 1, Place the large cylinder. When assembling, first start the flat push hydraulic cylinder on the base platform to drive the telescopic tongue to extend, and then use a crane to place the large cylinder in the circular placement groove of the support frame of the telescopic tongue. Step 2, Fix the large cylinder. After placing it, by starting the third electric cylinder, the output ends of the two third electric cylinders respectively drive the two forward clamping blocks to move relatively towards the position of the large cylinder, so as to clamp both sides of the large cylinder. When the forward clamping blocks move, they drive the support plate to move synchronously. Then start the fourth electric cylinder, and the output end of the fourth electric cylinder drives the lateral clamping block to move towards the side of the large cylinder and clamp it, so that the two lateral clamping blocks respectively clamp the other two sides of the large cylinder. Furthermore, the two forward clamping blocks and the two lateral clamping blocks all clamp the large cylinder and fix it at the top end of the support frame. Step 3, Install the middle cylinder. After clamping, continue to lift the middle cylinder with a crane and place it into the large cylinder. After inserting the middle cylinder into the large cylinder, move the telescopic tongue and push it to the side of the pressing platform. The pressing platform drives the lower pressing plate to move downwards, and after contacting the top end of the middle cylinder, continue to move downwards to press it into the large cylinder. Step 4, Install the guide sleeve. After placing the middle cylinder into the large cylinder, place the guide sleeve at the position where it contacts the thread of the large cylinder opening. Then connect two special wrenches to the guide sleeve respectively. By moving the flat push base, move the hexagonal rod above the special wrenches, and by starting the second electric cylinder, the output end of the second electric cylinder drives the hexagonal rod to move according to the positions of the two special wrenches, so that it moves directly above the special wrenches. Then start the first electric cylinder, and the output end of the first electric cylinder drives the connecting plate to move downwards, insert the hexagonal rod into the connecting port of the special wrench. Then start the first motor, and the output end of the first motor drives the rotating plate to rotate in the circular sliding groove in the rotating ring, thereby driving the hexagonal rod to rotate, driving the special wrench to rotate, install the guide sleeve on the large cylinder, and then the assembly is completed.

[0014] The beneficial effects of the embodiments of the present disclosure are: 1. In the present disclosure, when installing the middle cylinder and the large cylinder, the telescopic tongue can drive them to be pressed into the bottom ends of the platform and the lower pressing plate. By pressing down the platform to drive the lower pressing plate to move, the middle cylinder can be pressed into the large cylinder. Compared with manually holding the middle cylinder and moving it down into the large cylinder, it is much more labor-saving.

[0015] 2. In the present disclosure, when installing the guide sleeve on the large cylinder, the rotating assembly can drive a special wrench to rotate, and then drive the guide sleeve to be threadedly installed at the cylinder opening of the large cylinder. Compared with manually rotating the special wrench to drive the connection of the guide sleeve, it is much more labor-saving.

[0016] In summary, through the mutual cooperation among the telescopic tongue, the pressing platform, the flat-pushing base, and the rotating assembly, this device can press the middle cylinder into the large cylinder, and when threadedly installing the guide sleeve on the large cylinder, there is no need to manually hold a wrench for installation, which is more labor-saving and improves the assembly efficiency.

When the horizontal pushing hydraulic cylinder 19 is started, it drives the telescopic tongue 2 to move backward so that it moves out between the horizontal pushing base 4 and the pressing platform 3. Then, the large cylinder is lifted by a crane. Since a support frame 18 is fixedly installed at the bottom of the telescopic tongue 2 and a circular placement groove is provided at the center of the top of the support frame 18, it is placed into the circular placement groove of the support frame 18. After placement, the large cylinder is fixed on the support frame 18 through the clamping assembly.

The output end of the fourth electric cylinder 16 drives the side clamping blocks 17 to move towards and contact the side of the large cylinder. It should be added that the two side clamping blocks 17 are placed in a staggered manner relative to the large cylinder and are respectively located on the left and right sides of the large cylinder. Therefore, the two sides of the large cylinder can be clamped separately during clamping. At this time, the four sides of the large cylinder are fixedly clamped by the two forward clamping blocks 14 and the two side clamping blocks 17, and the large cylinder is fixed in the circular placement groove of the support 18.

[0029] As Figure 2 and Figure 6 shown, after fixation, lift the middle cylinder again by the crane and place it into the large cylinder. After placement, drive the lower pressing plate 20 to move upward through the pressing platform 3 so that it is located above the middle cylinder. Then drive the telescopic tongue 2 to move forward through the horizontal push hydraulic cylinder 19 so that the middle cylinder is located below the lower pressing plate 20. Start the pressing platform 3. The pressing platform 3 drives the lower pressing plate 20 to move downward, so as to press the middle cylinder into the large cylinder. It should be added that a lifting jack for controlling the lifting of the pressing platform 3 is installed on the basic platform 1. Therefore, the pressing platform 3 can drive the lower pressing plate 20 to move up and down. And the equipment is installed in the factory building. Therefore, hydraulic oil can be provided to the hydraulic cylinder through the hydraulic pump in the factory building to push the piston in the hydraulic cylinder.

[0030] After the loading is completed, place the guide sleeve at the threaded part of the large cylinder opening, and then install two special wrenches on the guide sleeve.

[0032] Working principle: During assembly, start the flat push hydraulic cylinder 19 to drive the telescopic tongue 2 to move backward, so that it moves out between the flat push base 4 and the pressing platform 3. Then use a crane to lift the large cylinder and place it into the circular placement groove of the support frame 18. After placement, fix the large cylinder on the support frame 18 through the clamping assembly. Start the third electric cylinder 13, and the output ends of the two third electric cylinders 13 drive the two positive clamping blocks 14 to move relatively, so as to contact and fixedly clamp both sides of the large cylinder. Then start the fourth electric cylinder 16, and the output end of the fourth electric cylinder 16 drives the lateral clamping block 17 to move towards the side of the large cylinder and contact it, so that the large cylinder is fixedly clamped in the circular placement groove of the support frame 18. After fixation, use the crane to lift the middle cylinder again and place it into the large cylinder. After placement, drive the lower pressing plate 20 to move upward through the pressing platform 3 so that it is located above the middle cylinder.

Start the pressing platform 3, and the pressing platform 3 drives the lower pressing plate 20 to move downward, so as to press the middle cylinder into the large cylinder. Finally, drive the flat push base 4 to move forward through the hydraulic cylinder, so that the hexagonal rod 12 moves above the special wrench. Then start the second electric cylinder 11 according to the distance between the two special wrenches. The output end of the second electric cylinder 11 drives the two hexagonal rods 12 to move, so that the two hexagonal rods 12 respectively move directly above the two hexagonal openings. Then start the first electric cylinder 8, and the output end of the first electric cylinder 8 drives the connecting plate 9 to move downward, and then drives the hexagonal rod 12 to move downward and insert into the hexagonal opening. Then start the first motor 7, and the output end of the first motor 7 drives the rotating plate 6 to rotate in the circular sliding groove of the rotating ring 5, and then drives the hexagonal rod 12 to rotate. Driven by the hexagonal rod 12, the special wrench drives the guide sleeve to rotate and thread it onto the cylinder opening of the large cylinder. After installation, take it out with a crane.

Furthermore, the two forward clamping blocks (14) and the two lateral clamping blocks (17) both clamp the large cylinder and fix it at the top end of the support frame (18); S3. Install the middle cylinder. After clamping, continue to lift the middle cylinder through a crane and place it into the large cylinder. After inserting the middle cylinder into the large cylinder, move the telescopic tongue (2) and push it to the side of the pressing platform (3). The pressing platform (3) drives the lower pressing plate (20) to move downward, and after contacting the top end of the middle cylinder, continue to move downward to press it into the large cylinder; S4. Install the guide sleeve. After placing the middle cylinder into the large cylinder, place the guide sleeve at the contact position with the thread of the large cylinder opening. Then connect two special wrenches to the guide sleeve respectively. By moving the flat push base (4), move the hexagonal rod (12) above the special wrenches. And by starting the second electric cylinder (11), the output end of the second electric cylinder (11) drives the hexagonal rod (12) to move according to the positions of the two special wrenches, so that it moves directly above the special wrenches. Then start the first electric cylinder (8). The output end of the first electric cylinder (8) drives the connecting plate (9) to move downward, insert the hexagonal rod (12) into the connection ports of the special wrenches. Then start the first motor (7). The output end of the first motor (7) drives the rotating plate (6) to rotate in the circular sliding groove in the rotating ring (5), and further drives the hexagonal rod (12) to rotate, drives the special wrenches to rotate, installs the guide sleeve on the large cylinder, and then the assembly is completed.
