Description

Technical Field

[0001] The utility model relates to an anti - reverse structure of a waiting device, belonging to the technical field of coal mine conveying equipment. Background Technique

[0002] ‌The underground waiting device‌, also known as the coal mine overhead passenger conveyor (commonly known as the monkey car), is a device specially designed to transport personnel in the inclined or horizontal roadway of a mine. Its working principle is similar to that of a ground tourist cableway. It uses a friction wheel driven by a motor on a speed reducer as a driving device, and an endless circulating steel wire rope in the air as the traction and load - bearing member. The steel wire rope is mainly tensioned by a tail tensioning device and supported by rope wheels along the way to maintain the sag and tension of the steel wire rope between the supporting wheels. The gripper connects the passenger chair to the steel wire rope and runs in a cycle, thus achieving the purpose of transporting personnel. This device has the characteristics of safe and reliable operation, convenient access for personnel, simple operation, easy maintenance, low power consumption, high transportation efficiency, and low one - time investment. It is a new type of modern mine personnel transportation equipment.

[0003] During the use of the waiting device, if some unexpected situations occur, such as the reverse sliding of the steel wire rope in the inclined roadway waiting area, when the weights on both sides are not equal, the sliding speed of the steel wire rope will become faster and faster, and very serious safety accidents will occur, resulting in the inability to guarantee the life safety of the employees taking the ride, and seriously affecting the production of the mining area, adding difficulties to the subsequent safety production work. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an anti - reverse structure of a waiting device to solve the technical problems existing in the above - mentioned prior art.

[0005] The technical solution adopted by the utility model is: the anti - reverse structure of the waiting device includes a first fixing plate arranged horizontally and a second fixing plate arranged vertically. The number of the first fixing plates is set to two and they are respectively fixed at the upper and lower ends on the same side of the second fixing plate. The first fixing plate and the second fixing plate are installed on a cross - beam. A horizontal plate arranged horizontally is fixed on the side of the second fixing plate away from the first fixing plate. Below the front and rear ends of the horizontal plate, a vertically - arranged mounting plate is respectively fixed. On the side of the two mounting plates close to each other, a vertically - arranged rotating plate is respectively rotatably connected. The rotating plate can only rotate counter - clockwise. The steel wire rope passes through between the two rotating plates. When the gripper of the waiting device passes through the rotating plate from left to right, the gripper of the waiting device can drive the rotating plate to rotate counter - clockwise.

[0006] Preferably, a limiting plate is fixed between the two mounting plates. The limiting plate is located on the left side of the upper middle part of the rotating plate, and the limiting plate restricts the clockwise rotation of the rotating plate.

[0007] Preferably, the upper part of the rotating plate is semi-circular, the middle part is rectangular, and the lower part is a right trapezoid, and the hypotenuse of the trapezoid is on the left side. The rotation center of the rotating plate coincides with the center of the semi-circular part.

[0008] Preferably, the distance between the two rotating plates is smaller than the size of the gripper of the waiting device.

[0009] Preferably, rib plates are fixed between the upper and lower sides of the horizontal plate and the second fixing plate.

[0010] Preferably, the two first fixing plates are connected by bolts and fixed on the cross beam.

[0011] The beneficial effects of the present invention: Compared with the prior art, the present invention can prevent accidental injury accidents caused by the reverse sliding of the steel wire rope during the operation of the waiting device, provide guarantee for the safety of waiting passengers, avoid the influence of the mining area on production due to accidents, and reduce losses. Description of the Drawings

[0012] Figure 1 is a schematic diagram of the overall structure of the present invention.

[0013] The reference numerals in the accompanying drawings of the specification include: first fixing plate 1, second fixing plate 2, horizontal plate 3, mounting plate 4, rib plate 5, rotating plate 6, limiting plate 7, steel wire rope 8. Detailed Embodiments

[0014] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0015] Embodiment 1:

[0016] The anti-reverse structure of the waiting device is as Figure 1As shown in the figure, it includes a first fixed plate 1 arranged horizontally and a second fixed plate 2 arranged vertically. The number of the first fixed plates 1 is set to two and they are respectively fixed at the upper and lower ends on the left side of the second fixed plate 2. The first fixed plate 1 and the second fixed plate 2 are installed on a cross beam made of I-beam. The two first fixed plates 1 are connected by bolts and fixed on the cross beam. A horizontal plate 3 arranged horizontally is fixed on the right side of the second fixed plate 2. Rib plates 5 are fixed between the upper and lower sides of the horizontal plate 3 and the second fixed plate 2 to strengthen the stability of the horizontal plate 3. Rectangular mounting plates 4 arranged vertically are respectively fixed below the front and rear ends of the horizontal plate 3. A rotating plate 6 arranged vertically is rotatably connected to the side of each of the two mounting plates 4 close to each other. The upper part of the rotating plate 6 is semi-circular, the middle part is rectangular, and the lower part is a right trapezoid with the hypotenuse of the trapezoid on the left side. The rotation center of the rotating plate 6 coincides with the center of the semi-circular part. A limiting plate 7 arranged vertically is fixed between the two mounting plates 4. The limiting plate 7 is located on the left side of the upper middle part of the rotating plate 6. The limiting plate 7 prevents the rotating plate 6 from rotating clockwise. The rotating plate 6 can only rotate counterclockwise and at most rotate 90°. The distance between the two rotating plates 6 is smaller than the size of the gripper of the waiting device. The steel wire rope 8 passes through between the two rotating plates 6. When the gripper of the waiting device passes through the rotating plate 6 from left to right, the gripper of the waiting device can drive the rotating plate 6 to rotate counterclockwise, so that the rotating plate 6 will not block the forward sliding of the steel wire rope 8. When the steel wire rope 8 slides in the reverse direction, since the rotating plate 6 cannot rotate clockwise, the rotating plate 6 will prevent the gripper of the waiting device from passing through, thereby preventing the reverse sliding of the steel wire rope 8, thus playing a role in preventing reverse rotation.

[0017] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
