Description

Technical Field

[0001] This utility model relates to the field of mine vehicle guardrail technology, and in particular to a safety protection device for an auxiliary inclined shaft. Background Technology

[0002] In mining operations, mine cars are needed to transport personnel or goods.

[0003] In the secondary inclined shaft, a barrier is usually installed to prevent the movement of mine cars. The barrier is usually made of metal rods and fixed to the ground with stakes to restrict its movement. Therefore, when a mine car needs to pass through the barrier, the mine car must be stopped first, and then workers must get out of the mine car to move the barrier. After the mine car has passed, the barrier must be manually moved back to its original position before the mine car can be put back on and moved. As a result, it takes a lot of time to open and close the barrier. The fact that workers stay outside the mine car for a long time increases the risk of injury to them. Utility Model Content

[0016] This invention utilizes the design of a blocking component, a driving component, and a control component. When the mine car approaches the position of the blocking bar, the worker can operate the control switch manually without getting out of the mine car. This causes the output end of the electric cylinder to retract, driving the blocking bar to rotate and thus opening the blocking bar to allow the mine car to pass. After the mine car has passed, the worker can manually operate the control switch to close the blocking bar. This eliminates the need for manual lifting of the blocking bar, saving manpower and preventing workers from staying outside the mine car for extended periods. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-5 The safety protection device shown is applied to the mine wall 1, with a ground surface 2 located at the bottom end of the mine wall 1, and also includes:

[0025] The blocking component 3 is used to restrict the movement of the mine car and is disposed on one side of the inner wall of the mine wall 1.

[0026] Drive component 4 is used to block the rotation of component 3. Drive component 4 is disposed on the front of the blocking component 3. Drive component 4 includes an electronically controlled cylinder 41.

[0027] Control component 6 is used to control the start and stop of the electric cylinder 41. Control component 6 is installed on the inner wall of the mine wall 1.

[0028] Specifically, the blocking assembly 3 includes a blocking rod 31. One end of the blocking rod 31 is provided with a mounting base 32 for connecting to the inner wall of the mine wall 1. One end of the blocking rod 31 is hinged to one end of the mounting base 32, and the other end of the mounting base 32 is fixedly connected to the inner wall of the mine wall 1. A through groove is provided on the front of the blocking rod 31, and a hinge is provided inside the through groove. A second rotating block 44 is fixedly connected to the output end of the electrically controlled cylinder 41. The hinge includes a second round rod 35. The bottom end of the second round rod 35 is fixedly connected to the bottom end of the inner wall of the through groove, and a first rotating block 44 is provided at the top end. A second round rod 35 is inserted into the first round hole. A mounting rod 33 for mounting an electric cylinder 41 is fixedly connected to the front of the mounting base 32. A limiting plate 36 for limiting the vertical displacement of the second rotating block 44 is fixedly connected to the top of the second round rod 35. A first round rod 34 is fixedly connected to the top of the mounting rod 33. A mounting plate 42 is fixedly connected to one end of the electric cylinder 41. A first rotating block 43 is fixedly connected to one end of the mounting plate 42. A second round hole is opened at the top of the first rotating block 43. The first round rod 34 is sleeved inside the second round hole.

[0029] Furthermore, two sets of blocking components 3 are symmetrically arranged, with both sets of blocking components 3 positioned on the same vertical plane. The ends of the two blocking rods 31 furthest from the mounting base 32 are positioned opposite each other. A circular groove is formed at the end of the blocking rod 31 closest to the mounting base 32, and a recess is formed at the end of the mounting base 32 closest to the blocking rod 31. A third circular rod is fixed to the bottom of the inner wall of the recess, and the third circular rod is fitted into the circular groove, thus creating a hinge between the blocking rod 31 and the mounting base 32. The bottom end of the second circular rod 35 is welded and fixed to the bottom end of the inner wall of the groove. The bottom end of the limiting plate 36 is welded and fixed to the top end of the second circular rod 35. The front of the mounting base 32 is welded and fixed to one end of the mounting rod 33, and the top end of the mounting rod 33 is welded and fixed to the first circular rod 31. The bottom end of the electric cylinder 41 is welded and fixed. The output end of the electric cylinder 41 is fixedly connected to the second rotating block 44 by bolts. By inserting the second round rod 35 into the first round hole of the second rotating block 44, and then welding the limiting plate 36 to the second round rod 35, the second rotating block 44 can be prevented from moving out of the second round rod 35. The end of the electric cylinder 41 away from the second rotating block 44 is fixedly connected to the mounting plate 42 by bolts. The mounting plate 42 is welded and fixed to the part that contacts the first rotating block 43. The first round rod 34 is welded and fixed to the mounting rod 33.

[0030] Specifically, a limiting column 5 is fixedly connected to the top of the ground 2 to restrict the rotation of the blocking rod 31.

[0031] Furthermore, the bottom end of the limiting column 5 is fixedly connected to the top end of the ground 2 by bolts. The limiting column 5 is located on the back side of the two blocking rods 31 on opposite sides, thereby limiting the rotation range of the blocking rods 31.

[0032] Specifically, the control component 6 includes a control box 61, one side of which is fixedly connected to one side of the inner wall of the mine wall 1. The input end of the control box 61 is electrically connected to a control switch 62 for outputting control signals. One side of the control switch 62 is fixedly connected to one side of the inner wall of the mine wall 1. The output end of the control box 61 is electrically connected to the input end of the electric cylinder 41.

[0033] Furthermore, at least four control switches 62 are provided, symmetrically arranged in pairs on both sides of the inner wall of the mine wall 1. The control switches 62 on one side of the inner wall of the mine wall 1 are symmetrically arranged on both sides with the blocking rod 31 as the vertical plane. This makes it convenient for workers on the mine car to start the electric cylinder 41 by operating the control switches 62 to open or close the blocking rod 31. In this way, workers do not need to get off the mine car to lift the blocking rod 31 when opening or closing it, which is more labor-saving and avoids the risks caused by workers staying outside the mine car for a long time.
