Technical Field

[0001] This invention belongs to the field of coal mine machinery technology, specifically relating to a monorail mine car lowering and straightening device. Background Technology

[0002] After a mine car is transported by a monorail in a coal mine, it needs to be lowered onto the ground track. However, due to the parallelism error and lateral swing error between the center line of the monorail and the center line of the ground track, manual pushing and pulling are required to straighten the lowering mine car so that the wheels of the mine car land exactly on the ground track. When manually pushing and pulling the mine car, the descent speed cannot be too fast, otherwise it is easy to cause injury accidents, thus affecting the efficiency of mine car hoisting. Summary of the Invention

[0003] Therefore, the purpose of this invention is to provide a monorail mine car lowering and straightening device, which can replace workers in straightening the hoisted mine car when it descends to the ground track, ensuring the safety of workers; the monorail mine car lowering and straightening device includes:

[0004] Two pairs of platform tracks, each pair of which is set on both sides of the mine car track;

[0005] A pair of straightening platforms, wherein the two straightening platforms are respectively mounted on a pair of platform tracks by rollers, and a traveling mechanism is provided between the straightening platforms and the platform tracks;

[0006] A swing frame, the lower end of which is hinged to the inner edge of each of the straightening platforms, and a plurality of first push-pull cylinders are connected between the swing frame and the straightening platform. One end of each first push-pull cylinder is hinged to the swing frame and the other end is hinged to the straightening platform.

[0007] The present invention also has the following optional features.

[0008] Optionally, it also includes multiple slide rail frames, which are laterally arranged on each of the straightening platforms. A transverse trolley is rotatably arranged on each slide rail frame. The front end of each transverse trolley extends from the middle of the swing frame. The front ends of the multiple transverse trolleys are hinged to their respective triangular seats on the same long shaft, and a long roller is fitted on the long shaft.

[0009] Optionally, rollers are provided on both sides of the front end of the transverse trolley, and a pair of levers are provided on the swing frame. The levers can drive the transverse trolley to move back and forth on the slide rail frame by moving the rollers.

[0010] Optionally, one end of the triangular seat is hinged to the front end of the transverse trolley, the second end of the triangular seat is connected to the long shaft, and the third end of the triangular seat is hinged to the transverse trolley with a second push-pull cylinder.

[0011] Optionally, both the first push-pull cylinder and the second push-pull cylinder are hydraulic cylinders, and an integrated valve group is provided on the uprighting platform. The integrated valve group is connected to the first push-pull cylinder and the second push-pull cylinder through hydraulic pipelines.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0023] Example 1

[0024] refer to Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides a monorail mine car lowering and straightening device, comprising: two pairs of platform rails 1, a pair of straightening platforms 2, and a swing frame 3. Each pair of platform rails 1 is respectively arranged on both sides of the mine car rail; the two straightening platforms 2 are respectively rolled on the pair of platform rails 1 by rollers, and a traveling mechanism is provided between the straightening platforms 2 and the platform rails 1; the lower end of the swing frame 3 is hinged to the inner edge of each straightening platform 2, and a plurality of first push-pull cylinders 4 are connected between the swing frame 3 and the straightening platform 2. One end of each first push-pull cylinder 4 is hinged to the swing frame 3, and the other end is hinged to the straightening platform 2.

[0025] When the monorail hoist lifts the mine car 14 to the position, it will lower the mine car 14 onto the mine car track 13. During the lowering process, the staff will control the two straightening platforms 2 to move along the platform tracks 1 on both sides of the mine car track 13 to the sides where the mine car 14 is lowered. When the mine car 14 is lowered to the lowest point, the first push-pull cylinder 4 extends and pushes the swing frame 3 to swing towards the inner edge of the straightening platform 2. If the mine car 14 deviates to one side during the lowering process, it will come into contact with the swing frame 3 on that side and be straightened to the other side by the swing frame 3, ensuring that the mine car 14 lands on the mine car track 13.

[0026] Example 2

[0027] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on embodiment 1, it also includes multiple slide rail frames 5, which are horizontally arranged on each straightening platform 2. A horizontal trolley 6 is rotatably arranged on each slide rail frame 5. The front end of each horizontal trolley 6 extends from the middle of the swing frame 3. A triangular seat 9 is provided at the front end of each horizontal trolley 6. A long shaft 7 is provided on the triangular seat 9. A long roller 8 is fitted on the long shaft 7.

[0028] Since the mine car 14 has wheels at the bottom, directly straightening the wheels will make the mine car 14 land more accurately on the mine car track 13. Multiple sliding frames 5 are horizontally arranged on the straightening platform 2, and horizontal trolleys 6 are mounted on the sliding frames 5. The rollers of the horizontal trolleys 6 roll in cooperation with the sliding frames 5. The front end of the horizontal trolleys 6 extends from the middle of the swing frame 3. Long shafts 7 are longitudinally arranged at the front ends of the multiple horizontal trolleys 6, and long rollers 8 are mounted on the long shafts 7. During the process of the first push-pull cylinder 4 extending and driving the swing frame 3 to swing towards the center of the two tracks, the long rollers 8 are used to horizontally straighten the mine car 14. Then, the long rollers 8 are moved downwards by the triangular seat 9, simultaneously controlling the descent of the mine car 14, ensuring that the wheels of the mine car 14 land on the mine car track 13.

[0029] Example 3

[0030] refer to Figure 4 and Figure 5 Based on embodiment 2, rollers are respectively provided on both sides of the front end of the transverse trolley 6, and a pair of levers 301 are provided on the swing frame 3. The levers 301 can drive the transverse trolley 6 to move back and forth on the slide rail frame 5 by moving the rollers.

[0031] When the swing frame 3 swings towards the mine car track 13, it straightens the falling mine car 14. The swing frame 3 uses the lever 301 to move the rollers, thereby causing the transverse trolley 6 to move forward on the slide rail frame 5, extending the long shaft 7 and long roller 8 forward to straighten the wheels of the falling mine car 14. When the swing frame 3 swings backward, the lever 301 can move the rollers on the transverse trolley 6, thereby causing the transverse trolley 6 to move backward on the slide rail frame 5, retracting the long shaft 7 and long roller 8 backward.

[0032] Example 4

[0033] refer to Figure 3 , Figure 4 and Figure 5 Based on embodiment 3, one end of the triangular seat 9 is hinged to the front end of the transverse trolley 6, the second end of the triangular seat 9 is connected to the long shaft 7, and the third end of the triangular seat 9 is hinged to the transverse trolley 6 with a second push-pull cylinder 10.

[0034] Because the axle ends of the wheels on both sides of the mine car 14 protrude, the long roller 8 on the long axle 7 needs to straighten the wheels 14 and move the axle ends aside. This requires a short retraction of the long axle 7 and the long roller 8. Therefore, a triangular seat 9 is hinged to the front end of the transverse trolley 6. One end of the triangular seat 9 is connected to the long axle 7, and the second end of the triangular seat 9 is hinged to the transverse trolley 6. The third end of the triangular seat 9 is hinged to the second push-pull cylinder 10. When the second push-pull cylinder 10 retracts, it pulls one end of the triangular seat 9 back, causing the long axle 7 at the other end of the triangular seat 9 to extend. After the long roller 8 on the long axle 7 straightens the wheels of the mine car 14, the second push-pull cylinder 10 extends, pushing one end of the triangular seat 9 outward, causing the long axle 7 and the long roller 8 at the other end of the triangular seat 9 to retract and avoid the axle ends of the wheels of the mine car 14.

[0035] Example 5

[0036] refer to Figure 2 , Figure 3 and Figure 5 Based on embodiment 4, the first push-pull cylinder 4 and the second push-pull cylinder 10 are both hydraulic cylinders. An integrated valve seat is placed on the uprighting platform 2, and the integrated valve seat is connected to the first push-pull cylinder 4 and the second push-pull cylinder 10 through hydraulic pipelines.

[0037] Both the first push-pull cylinder 4 and the second push-pull cylinder 10 are hydraulic cylinders. The rod chamber and rodless chamber of each first push-pull cylinder 4 and second push-pull cylinder 10 are connected to the integrated valve seat through hydraulic lines. The extension and retraction of the first push-pull cylinder 4 and the second push-pull cylinder 10 can be controlled by operating the integrated valve seat.

[0038] Example 6

[0039] refer to Figure 3 and Figure 6 Based on embodiment 1, the walking mechanism includes a moving motor 11, which is fixed on the straightening platform 2. A rack 12 is provided between the platform tracks 1. A gear 1101 is provided on the main shaft of the moving motor 11, and the gear 1101 meshes with the rack 12.

[0040] By controlling the moving motor 11 to drive the gear 1101 to rotate, the straightening platform 2 can be moved along the rack 12, thereby moving the straightening platform 2 to both sides below the hoisted mine car 14.
