Description

Technical Field

[0001] This utility model relates to the field of overhead personnel carrier technology, specifically a device for preventing the steel wire rope of an overhead personnel carrier from detaching. Background Technology

[0002] In coal mine operations, personnel often use a type of personnel carrier, also known as an aerial personnel carrier or, colloquially, a "monkey car," to transport people between the surface and underground. The principle is that a winch drives a steel cable above the mine roadway, and the personnel carrier is suspended on this cable. People sit in the carrier and descend into the mine or ascend back to the surface along the cable. Currently, most vehicles use a single-seat type. The carrier has a hook at the top, with a pole connected to it. A seat is attached to the lower end of the pole. Personnel sit in the seat, hold onto the pole, and move along with the steel cable. Typically, a turntable is installed underground to wind the steel cable, supporting the cable's ends and creating a closed-loop system.

[0003] Upon investigation, a Chinese utility model patent discloses a device for preventing the steel wire rope of an overhead personnel carrier from detaching (publication number: CN205186148U), which includes a crossbeam, a column, a turntable, a steel wire rope, a notch, and a pin; the crossbeam is installed on the top of the tunnel in front of the turntable.

[0004] Although the aforementioned patent can effectively prevent the steel cable of the overhead passenger vehicle from detaching at the turntable by setting the pin, the steel cable may loosen over time. While the pin in this device can prevent the loose steel cable from falling off the turntable, when the passenger vehicle moves with the steel cable, the loose steel cable will cause the passenger vehicle to sag due to gravity, shortening the ground clearance and even causing friction with the ground, affecting the normal use of the passenger vehicle.

[0005] Therefore, this utility model provides a device to prevent the steel wire rope of an overhead personnel carrier from detaching, in order to solve the above-mentioned problems. Utility Model Content

[0006] Technical problems to be solved:

[0007] This utility model provides a device to prevent the steel wire rope of an overhead personnel carrier from detaching, aiming to solve the problems mentioned in the background art.

[0008] Technical solution:

[0009] To achieve the above objectives, this utility model provides the following technical solution: it includes an upper shell, a lower shell, and multiple turntables. The upper shell is provided with multiple positioning blocks, and the lower shell is provided with multiple positioning grooves, with the positioning blocks and positioning grooves being adapted to each other. An adjustment mechanism is provided between the upper shell and the lower shell. The adjustment mechanism includes a circular plate and multiple moving blocks. The multiple turntables are rotatably connected to the multiple moving blocks respectively. The circular plate is provided with a spiral groove, and the multiple moving blocks are movably connected to the spiral groove.

[0010] As a preferred technical solution of this application, the circular plate is rotatably connected between the upper shell and the lower shell, and a toothed ring is fixedly connected to the bottom of the circular plate, with a gear meshing at the bottom of the toothed ring.

[0011] As a preferred technical solution of this application, the lower housing is provided with an installation groove, the gear is rotatably connected in the installation groove, the upper housing is provided with multiple sliding grooves, and the multiple moving blocks are slidably connected in the multiple sliding grooves respectively.

[0012] As a preferred technical solution of this application, a support frame is bolted to the movable block, a pulley is rotatably connected to the support frame, and an mounting block is provided above the pulley. The mounting block is fixedly connected to the support frame by bolts.

[0013] As a preferred technical solution of this application, a rotating seat is rotatably connected to the outer wall of the lower housing, and the rotating seat is fixed coaxially with the gear.

[0014] As a preferred technical solution of this application, a motor is fixedly connected in the mounting slot, and the output end of the motor is coaxially fixed with the gear.

[0015] Beneficial effects:

[0016] By adjusting the distance between multiple turntables using an adjustment mechanism, when the wire rope becomes loose during use, the motor is started or the rotating seat is rotated to drive the gears to rotate. The gears drive the adjustment mechanism through the meshing gear rings, causing multiple moving blocks in the adjustment mechanism to move outward synchronously. The moving blocks drive the turntables to move, increasing the distance between the turntables, thereby tightening the loose wire rope and preventing the personnel carrier on the aerial vehicle from sag too much due to gravity and rubbing against the ground, which would affect the normal use of the personnel carrier.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0026] This utility model provides a device for preventing the steel wire rope of an overhead personnel carrier from detaching, such as... Figures 1-5 The technical solution includes an upper shell 1, a lower shell 2, and multiple turntables 3. The upper shell 1 and the lower shell 2 are fixed together by bolts. The upper shell 1 is provided with multiple positioning blocks 10, and the lower shell 2 is provided with multiple positioning grooves 15. The positioning blocks 10 and positioning grooves 15 are adapted to each other. During installation, the positioning blocks 10 on the upper shell 1 are inserted into the positioning grooves 15 on the lower shell 2. An adjustment mechanism is provided between the upper shell 1 and the lower shell 2. The adjustment mechanism includes a circular plate 11 and multiple moving blocks 8. The multiple turntables 3 are rotatably connected to the multiple moving blocks 8. The circular plate 11 is provided with a spiral groove 12, and the multiple moving blocks 8 are movably connected to the spiral groove 12. By setting the adjustment mechanism to adjust the distance between the multiple turntables 3, when the wire rope becomes loose during use, the moving blocks 8 in the adjustment mechanism drive the turntables 3 to move, thereby increasing the distance between the turntables 3, thus tightening the loose wire rope and preventing the personnel carrier on the aerial vehicle from sag too much due to gravity and rubbing against the ground, which would affect the normal use of the personnel carrier.

[0027] A support frame 5 is bolted to the movable block 8. A pulley 6 is rotatably connected to the support frame 5. An installation block 7 is provided above the pulley 6. The installation block 7 is fixedly connected to the support frame 5 by bolts. The pulley 6 is used to prevent the wire rope from slipping off and to reduce the friction of the wire rope. The installation block 7 is removed and the wire rope is placed on the pulley 6. Then, the installation block 7 is fixed above the pulley 6 with bolts, which can prevent the wire rope from slipping off.

[0028] A circular plate 11 is rotatably connected between the upper housing 1 and the lower housing 2. A toothed ring 13 is fixedly connected to the bottom of the circular plate 11, and a gear 16 meshes with the bottom of the toothed ring 13. An installation groove is provided on the lower housing 2, and the gear 16 is rotatably connected in the installation groove. Multiple sliding grooves 9 are provided on the upper housing 1, and multiple moving blocks 8 are slidably connected in the multiple sliding grooves 9 respectively. A rotating seat 4 is rotatably connected to the outer wall of the lower housing 2. The rotating seat 4 is coaxially fixed with the gear 16. A motor 14 is fixedly connected in the installation groove, and the output end of the motor 14 is coaxially fixed with the gear 16.

[0029] It should be noted that the gear 16 in the adjustment mechanism is connected to the motor 14 and the rotating seat 4. The gear 16 can be driven to rotate by the operator starting the motor 14 or by rotating the rotating seat 4 with the help of tools. This prevents the operator from being unable to adjust the distance between the turntables 3 due to loss of power or sudden failure of the motor 14. The motor 14 is connected to an external power source through wires. The external power source includes a battery for providing power to the motor 14 and a control switch for controlling its start and stop. The external power source is existing technology. When the motor 14 is not in operation, its output end can rotate. The specific model and specifications of the motor 14 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be described in detail.

[0030] In summary: During operation, starting the motor 14 or rotating the rotating seat 4 drives the gear 16 to rotate. The rotating gear 16 drives the circular plate 11 to rotate through the meshing gear ring 13. The rotating circular plate 11 drives multiple moving blocks 8 to move synchronously through the spiral groove 12. The moving blocks 8 drive the turntable 3 to move outward, thereby increasing the distance between the turntables 3 and tightening the loose wire rope.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
