Description

Technical Field

[0001] The utility model belongs to the technical field of scraper machine disassembly equipment, and in particular relates to a middle trough disassembly device. Background Art

[0002] In the long-wall retreating fully mechanized mining face in the coal mine, when the overall length of the drift is short or when it transitions to another drift, it is impossible to use a belt conveyor to transfer coal. In this case, a scraper with an open bottom for the drift is required. The length of the scraper becomes shorter as the working face moves forward, and the middle trough needs to be continuously removed. The unloading section and the tail of the scraper move forward as the middle trough is removed. Due to the large weight of a single section of the middle trough, the traditional manual chain reversal is inefficient for disassembly and assembly, and is prone to accidents. Summary of the invention

[0005] Furthermore, the rotating bracket includes a column, the upper end of the column is rotatably provided with a crossbeam, and the hanger is arranged on the crossbeam.

[0006] Furthermore, a vertical power member is provided between the cross beam and the hanger, the upper end of the vertical power member is connected to the cross beam, and the lower end of the vertical power member is connected to the hanger.

[0007] Furthermore, the upper end of the vertical power member is a fixed end, a slide rail is horizontally arranged on the crossbeam, and the fixed end of the vertical power member is slidably arranged on the slide rail.

The first end of the connecting trough 4 is detachably connected to the middle trough 71 to be disassembled, and the second end of the connecting trough 4 is connected to the connecting seat 5 of the end bracket. The second end of the connecting trough 4 is also connected to the unloading section and the tail of the scraper at the rear (not shown in the figure). The unloading section and the tail of the scraper at the rear are conventional structures of the scraper conveyor, which are common knowledge for those skilled in the art and will not be described here.

[0020] The first end of the connecting groove 4 can be detachably connected to the middle groove 71 to be disassembled by means of bolts or dumbbell pins. Of course, it can also be connected to the middle groove 71 to be disassembled by other conventional detachable connection methods, which will not be repeated here.

[0021] The second end of the connecting groove 4 can be detachably connected to the connecting base 5 of the end bracket by means of a pin connection. Of course, it can also be connected to the connecting base 5 of the end bracket by other conventional connection methods, which will not be repeated here.

[0022] Preferably, the rotating bracket 1 comprises a column 11, and a crossbeam 12 is rotatably provided at the upper end of the column 11. The crossbeam 12 can be rotatably installed at the upper end of the column 11 through a bearing. The hanger 3 is arranged on the crossbeam 12.

[0023] Preferably, a vertical power member is provided between the cross beam 12 and the hanger 3 , the upper end of the vertical power member is connected to the cross beam 12 , and the lower end of the vertical power member is connected to the hanger 3 .

[0024] Further preferably, the upper end of the vertical power member is a fixed end, a slide rail 6 is horizontally arranged on the cross beam 12, and the fixed end of the vertical power member is slidably arranged on the slide rail 6. The vertical power member is a hoisting hydraulic cylinder 2, and of course, other conventional power members such as air cylinders and electric cylinders that can provide power for the hoist to move up and down can also be selected, and they will not be described one by one here.

[0025] Preferably, a pushing force member is also provided on the connecting seat 5. The pushing force member is a pushing hydraulic oil cylinder 9. Of course, other conventional power members capable of providing pushing force, such as a cylinder and an electric cylinder, can also be selected, and will not be described one by one here.

[0026] Under the action of the push hydraulic cylinder 9, the process and working principle of the end bracket moving forward are common knowledge to those skilled in the art and will not be described in detail here.

[0027] Preferably, the middle tank disassembly device further comprises a transfer trolley 8, which is used to transfer the disassembled middle tank, and the transfer trolley 8 and the column 11 of the rotating bracket 1 are arranged on the same side of the connecting tank 4.

[0028] The following is a detailed description of the process of disassembling the middle tank 71 to be disassembled using the middle tank disassembly device of the utility model:

[0029] The first end of the middle groove 71 to be disassembled is detachably connected to the adjacent middle groove 72, and the second end of the middle groove 71 to be disassembled is detachably connected to the first end of the connecting groove 4. When the middle groove 71 to be disassembled is to be disassembled, the first end of the middle groove 71 to be disassembled is removed from the adjacent middle groove 72, and the second end of the middle groove 71 to be disassembled is removed from the first end of the connecting groove 4.

[0030] Manually rotate the crossbeam 12 of the rotating bracket 1 until the sling 3 is located above the middle groove 71 to be disassembled. If the sling 3 is not directly above the middle groove 71 to be disassembled, manually push the lifting hydraulic cylinder 2 to move along the slide rail 6 until the sling 3 is directly above the middle groove 71 to be disassembled. The action end of the lifting hydraulic cylinder 2 extends out, the sling 3 clamps the middle trough 71 to be disassembled (the structure and working principle of the sling are all well-known technologies and will not be described in detail here), the action end of the lifting hydraulic cylinder 2 is retracted, the sling 3 lifts the middle trough 71 to be disassembled, and the crossbeam 12 is manually rotated to move the sling 3 to the top of the transfer trolley 8 waiting on one side. If the sling 3 is not directly above the transfer trolley 8, the lifting hydraulic cylinder 2 is manually operated to move horizontally along the slide rail 6 until the sling 3 is adjusted to be directly below the transfer trolley 8. The action end of the lifting hydraulic cylinder 2 extends out, and the sling 3 places the disassembled middle trough on the transfer trolley 8, and then the action end of the lifting hydraulic cylinder 2 is retracted. At this time, the middle trough is disassembled.

[0031] After the middle groove is removed, the pushing force is provided by the pushing hydraulic cylinder 9 of the end bracket to push the connecting groove 4 forward, push the connecting groove 4 to the previous adjacent middle groove 72, and connect the connecting groove 4 with the previous adjacent middle groove 72. The previous adjacent middle groove 72 becomes the middle groove 71 to be disassembled.

[0032] At the same time, the end bracket realizes the forward movement of the unloading section and the tail of the scraper conveyor (not shown in the figure). It is common knowledge for those skilled in the art to realize the forward movement of the unloading section and the tail of the scraper conveyor through the end bracket, and will not be repeated here.

[0033] The hydraulic power sources used in this embodiment all come from the downhole hydraulic system, making full use of the downhole hydraulic system.
