Technical Field
[0001] This utility model relates to the field of monkey car technology, specifically a monkey car protection and locking control device. Background Technology
[0002] A "monkey car" is a common name for an elevated passenger transport device, a new type of personnel transport equipment in inclined or horizontal mine tunnels. The working principle of a monkey car is that an electric motor drives a friction wheel on a reducer as the driving device, and an elevated, continuously circulating steel wire rope serves as the traction load. The steel wire rope is tensioned by a tensioning device at the tail end and supported by rope pulleys along the way. A cable grip connects the passenger chair to the steel wire rope, which then circulates along with the rope, thus achieving the purpose of transporting personnel. Commonly used monkey cars include friction-type detachable monkey cars, which consist of a friction plate, a hanging shaft, and a chair mounted on the hanging shaft. The chair can be hung on a cable and moves along with the cable by friction.
[0003] When existing monkey car passenger transport systems are used in steep roadways, slippage and rollover can occur due to insufficient friction at the connection between the friction plate and the cable, posing a safety hazard. Utility Model Content
[0004] The purpose of this utility model is to provide a protective locking and control device for monkey car transport, in order to solve the problem mentioned in the background art that when the existing monkey car transport system for steep slope tunnels is used, the vehicle may slip due to insufficient friction at the connection between the friction plate and the cable, which poses a safety hazard.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a monkey car protection locking and control device, comprising a monkey car body, a fixed connecting arm fixedly connected to the upper surface of one end of the fixed connecting arm, a limiting support frame fixedly connected to the upper end of the fixed connecting arm, an installation slot provided on the surface of the limiting support frame, a support guide rod fixedly connected to the lower side surface of the installation slot, clamping blocks installed on the outer surfaces of the two support guide rods, an adjusting screw provided on the upper surface of the limiting support frame, a positioning baffle installed on the outer surface of the adjusting screw, two guide sliders through the upper surface of the limiting support frame, a pressing block fixedly connected to the lower surface of the guide sliders, a support shaft provided on the inner wall of the installation slot cavity, and a locking groove provided at one end of the support shaft, a locking block fixedly connected to the side surface of the guide sliders, a linkage roller fixed between the two support shafts, and a speed sensor fixedly connected to the top surface of the installation slot cavity.
[0006] Preferably, the fixed connecting arm is fixedly connected to the monkey car body by bolts, the supporting guide rod and the clamping block are slidably connected, and a spring is connected between the supporting guide rod and the clamping block.
[0007] Using the above technical solution, the bolt-fixed connection is convenient for installation and disassembly, and facilitates the adjustment, replacement or repair of the limit support frame during the production, installation and subsequent maintenance of the monkey car.
[0008] Preferably, the upper side surface of the clamping block is inclined, and the opposing surfaces of the two clamping blocks are provided with arc-shaped grooves.
[0009] By adopting the above technical solution, the inclined design of the upper side surface of the clamping block can guide the cable if the cable position is slightly deviated during the installation of the cable or the operation of the maneuver, making it easier for the cable to smoothly enter between the two clamping blocks, reducing the installation difficulty and improving the fault tolerance during operation.
[0010] Preferably, the adjusting screw is rotatably connected to the limiting support structure, the adjusting screw is threadedly connected to the positioning baffle, and the lower surface of the positioning baffle is fixedly connected to the upper ends of the two guide sliders.
[0011] By adopting the above technical solution, the rotational connection between the adjusting screw and the limiting support frame and the threaded connection with the positioning baffle can be used to precisely adjust the height of the positioning baffle by rotating the adjusting screw. Since the positioning baffle is connected to the guide slider, the position of the squeezing block can be controlled.
[0012] Preferably, the guide slider is slidably connected to the limiting support structure, and the lower surface of the compression block is arc-shaped.
[0013] By adopting the above technical solution, the sliding connection between the guide slider and the limiting support frame ensures that the extrusion block can move smoothly up and down on the limiting support frame, making the movement trajectory of the extrusion block stable and controllable.
[0014] Preferably, the support shaft and the limiting support structure are rotatably connected, the locking groove is a cross-shaped design, and the locking block is correspondingly set with the locking groove.
[0015] Using the above technical solution, the cross-shaped locking groove and the locking block cooperate to achieve precise positioning and connection between the support shaft and the guide slider. When the guide slider moves to a specific position, the locking block can be accurately embedded in the locking groove to lock the support shaft and the guide slider together, preventing relative displacement between the two during the operation of the monkey car.
[0016] Preferably, the surface of the linkage roller is designed with an arc-shaped concave shape, and the arc-shaped surface of the linkage roller is provided with rubber particles.
[0017] By adopting the above technical solution, the arc-shaped concave design on the surface of the linkage roller matches the shape of the cable, further increasing the contact area between the linkage roller and the cable and improving the efficiency of frictional force transmission between the two.
[0018] Compared with the prior art, the beneficial effects of this utility model are: the monkey car protection locking and control device:
[0019] 1. The special design of the contact parts between the clamping blocks and the squeezing blocks and the cable, such as the arc-shaped grooves on the facing surfaces of the clamping blocks and the arc-shaped design on the lower surface of the squeezing blocks, greatly increases the contact area and friction with the cable. Combined with the spring between the support guide rod and the clamping blocks, the clamping blocks can always maintain a suitable clamping force on the cable, effectively preventing slippage and rollover due to insufficient friction, and ensuring the safety of personnel transportation.
[0020] 2. The threaded connection between the adjusting screw and the positioning baffle allows for precise control of the position of the compression block by rotating the adjusting screw, thereby flexibly adjusting the compression force on the cable. This design enables the device to adapt to cables of different thicknesses and wear levels, meeting the friction requirements under various working conditions and improving the stability and adaptability of the maneuvering vehicle.
[0021] 3. By installing a speed sensor on the top surface of the slotted cavity, the speed of the linkage roller can be monitored in real time. Once slippage occurs, abnormal changes in speed can be detected in time, providing data support for subsequent braking and other protective measures, realizing early warning of faults and reducing the risk of accidents.

[0029] 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.
[0030] Please see Figure 1-6 This utility model provides a technical solution: a monkey car protection locking and control device, including a monkey car body 1, a fixed connecting arm 2, a limiting support frame 3, an installation slot 4, a support guide rod 5, a clamping block 6, an adjusting screw 7, a positioning baffle 8, a guide slider 9, a pressing block 10, a support shaft 11, a locking groove 12, a locking block 13, a linkage roller 14, and a speed sensor 15. The monkey car body 1 has a fixed connecting arm 2 fixedly connected to one end of its upper surface. The upper end of the fixed connecting arm 2 is fixedly connected to the limiting support frame 3. The fixed connecting arm 2 and the monkey car body 1 are fixedly connected by bolts. The support guide rod 5... The clamping block 6 is slidably connected to the support guide rod 5, and a spring is connected between the clamping block 6 and the support guide rod 5. The monkey car body 1 is stably connected to the limiting support frame 3 through the fixed connecting arm 2. The fixed connecting arm 2 is fixed to the monkey car body 1 with bolts for easy installation and disassembly. According to the actual situation of the cable, the adjusting screw 7 is rotated. The adjusting screw 7 is rotatably connected to the limiting support frame 3 and threadedly connected to the positioning baffle 8. The positioning baffle 8 drives the guide slider 9 to slide on the limiting support frame 3. The guide slider 9 and the limiting support frame 3 form a sliding connection, thereby adjusting the position of the squeezing block 10 to adapt to the installation requirements of different cables.
[0031] The surface of the limiting support frame 3 has an installation slot 4. A support guide rod 5 is fixedly connected to the lower side surface of the installation slot 4. Clamping blocks 6 are installed on the outer surfaces of the two support guide rods 5. An adjusting screw 7 is provided on the upper surface of the limiting support frame 3. A positioning baffle 8 is installed on the outer surface of the adjusting screw 7. The upper side surface of the clamping blocks 6 is inclined, and the facing surfaces of the two clamping blocks 6 are provided with arc-shaped grooves. The adjusting screw 7 is rotatably connected to the limiting support frame 3, and the adjusting screw 7 is threadedly connected to the positioning baffle 8. The lower surface of the positioning baffle 8 is fixedly connected to the upper ends of the two guide sliders 9. The cable enters between the two clamping blocks 6. The lifting and lowering of the squeezing block 10 squeezes the inclined surface of the clamping block 6, which facilitates the two clamping blocks 6 to slide towards each other and clamp the cable. The arc-shaped grooves on the facing surfaces of the two clamping blocks 6 are adapted to the shape of the cable, increasing the contact area and enhancing the friction.
[0032] Two guide sliders 9 are installed through the upper surface of the limiting support frame 3. A pressing block 10 is fixedly connected to the lower surface of the guide sliders 9. The guide sliders 9 and the limiting support frame 3 form a sliding connection. The lower surface of the pressing block 10 is arc-shaped. The support shaft 11 and the limiting support frame 3 form a rotating connection. The locking groove 12 is cross-shaped. The locking block 13 is correspondingly set with the locking groove 12. When the device is disassembled, the two guide sliders 9 rise up, so that the device is in the unlocked state. At this time, the guide sliders 9 drive the locking block 13 to be locked into the locking groove 12, so that the linkage roller 14 will not rotate, thus preventing the speed sensor 15 from detecting and generating a false alarm.
[0033] The inner wall of the cavity with slot 4 is provided with a support shaft 11, and one end of the support shaft 11 is provided with a locking groove 12. A locking block 13 is fixedly connected to the side surface of the guide slider 9. A linkage roller 14 is fixed between the two support shafts 11. A speed sensor 15 is fixedly connected to the top surface of the cavity with slot 4. After the guide slider 9 descends, it squeezes the clamping block 10 and pushes the clamping block 6 to clamp and work. At this time, the locking block 13 on the surface of the guide slider 9 is released from the locking groove 12. The linkage roller 14 is attached to the surface of the cable through rubber particles. When the device becomes loose, the linkage roller 14 will be driven by the cable to rotate. At this time, the speed sensor 15 will detect the rotation of the linkage roller 14 and send a signal, thereby immediately triggering the operation lock and stopping the operation of the monkey car, which increases the safety of the device.
[0034] Working principle: When using the monkey car protection interlocking control device, before the monkey car starts running, the adjusting screw 7 can be rotated according to the cable condition, which drives the positioning baffle 8 to move. The positioning baffle 8 drives the guide slider 9 to slide on the limit support frame 3, thereby adjusting the position of the squeezing block 10. The squeezing block 10 squeezes the clamping block 6, so that the clamping block 6 slides on the surface of the support guide rod 5 to clamp the cable. The arc-shaped groove on the opposite surface increases the contact area with the cable and enhances the friction. The speed sensor 15 installed on the top surface of the slotted cavity 4 monitors the speed of the linkage roller 14 in real time. When the friction between the cable and the friction plate is insufficient and slippage occurs, the speed of the linkage roller 14 will change abnormally. After the speed sensor 15 detects the abnormality, it can issue a warning signal in time to prompt the staff to take measures, which increases the overall practicality.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
