Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to a monorail pulley device with a manual braking structure. Background Technology
[0002] Monorail pulleys have a wide range of applications in many industrial scenarios and underground operations. Most mining faces are equipped with monorail tracks. When there are not enough monorail locomotives and personnel, it is impossible to guarantee that monorail locomotives can be used for transportation at every working face. Moreover, when transporting some small parts, pipes and other materials, using monorail locomotives is both time-consuming and uneconomical. At this time, monorail pulleys become a convenient transportation tool. In tunnels with gentle slopes, when using ordinary monorail pulleys for transportation, it is difficult to manually control the running speed and to stop the heavy load in time when needed, which poses a significant safety risk, especially when the heavy load has a large inertia or the slope is steep, which may lead to accidents. In traditional monorail pulleys, braking is usually achieved by blocking during transport. However, blocking requires a heavy device to make contact with the monorail pulley. Inside a mine, the load on the monorail pulley has a large inertia during operation, and blocking may result in an unsatisfactory braking effect. Utility Model Content
[0003] The purpose of this invention is to provide a monorail hoisting pulley device with a manual braking structure. In this device, the braking structure is installed in conjunction with a first roller in the pulley assembly. During the operation of the pulley assembly, by moving the movable frame, the contact between the movable arc plate and the first roller is effectively achieved, thereby effectively ensuring the operating speed of the pulley assembly. This effectively ensures speed control when the pulley assembly is running on monorails with large inertia or steep slopes, avoiding dangerous situations. Manual braking can be performed on gentle downhill sections or when stopping to counteract the inertia and downward force of the load, achieving the purpose of slowing down or stopping the operation and reducing safety risks. At the same time, in some scenarios where large monorail hoisting vehicles are not required, using this monorail hoisting pulley device with a manual braking structure can also achieve energy saving and consumption reduction, thus solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A monorail hanging pulley device with a manual braking structure includes a single track; a pulley assembly is movably mounted on the single track; the pulley assembly includes two symmetrical side plates; two first rollers are provided on the inner side of each of the two side plates; the first rollers are in contact with the surface of the single track; and second rollers are also installed at both ends of the side plates. The first roller on one side plate is installed in conjunction with the braking structure; the braking structure includes a movable arc plate and a fixed arc plate; wherein the fixed arc plate is fixedly installed to the side plate by bolts; As a further technical solution of this utility model, the movable arc plate and the fixed arc plate are hinged together; the connection is installed by a strut and the top of the side plate. As a further technical solution of this utility model, the side of the movable arc plate away from the first roller is movably installed to the top of the movable frame through a fixing block and a pin; the movable frame is bent; the bent part of the movable frame is movably installed between the side plate and the pivot. As a further technical solution of this utility model, the bottom of the two side plates are fixedly installed by multiple connecting rods; wherein the two ends of the connecting rods are provided with fastening nuts; the fastening nuts are detachably installed with the connecting rods by means of pins; and a hook is fixedly installed on one of the connecting rods. As a further technical solution of this utility model, the first roller and the second roller are arranged perpendicularly to each other; wherein the second roller is in contact with the sides of the single track. Compared with the prior art, the beneficial effects of this utility model are: In this invention, the top of the single track is fixedly installed to the mine shaft, and the first roller on the inner side of the side plate of the running pulley assembly contacts the top surface of the bottom support beam of the single track. At the same time, the second rollers movably installed at both ends of the side plate contact the side surface of the bottom support beam of the single track. This effectively ensures stability during the operation of the pulley assembly and prevents the pulley assembly from shifting or shaking on the single track. In this utility model, the bottom of the two side plates are effectively connected and installed by multiple connecting rods, fastening nuts and pins to ensure that the side plates on both sides are symmetrically arranged and that the first roller and the second roller on the side plates on both sides rotate synchronously. In this invention, during operation, when braking is required, the operator pulls the movable frame outward, causing the movable frame to move and the arc-shaped plate to fit against the surface of the first roller via the fixed block and pin, increasing the friction between the first roller and the movable arc-shaped plate and ensuring the braking effect.

The first roller 21 on one side plate 20 is installed in conjunction with the braking structure 3; the braking structure 3 includes a movable arc plate 30 and a fixed arc plate 31; wherein the fixed arc plate 31 is fixedly installed to the side plate 20 by bolts; By adopting the above technical solution, during use, the top of the single track 1 is fixedly installed to the mine shaft, and the first roller 21 on the inner side of the side plate 20 of the running pulley assembly 2 contacts the top surface of the bottom support beam of the single track 1. At the same time, the second roller 23, which is movably installed at both ends of the side plate 20, contacts the side surface of the bottom support beam of the single track 1. In this way, the stability of the pulley assembly 2 is effectively guaranteed during operation, and the pulley assembly 2 is prevented from shifting or shaking on the single track 1. In this embodiment, the movable arc plate 30 and the fixed arc plate 31 are hinged together; the connection is installed by a strut that engages with the top of the side plate 20. In this embodiment, the side of the movable arc plate 30 away from the first roller 21 is movably installed to the top of the movable frame 33 via a fixing block and a pin; the movable frame 33 is bent; the bent part of the movable frame 33 is movably installed between the side plate 20 via a rotating shaft 34. By adopting the above technical solution, the bottom of the two side plates 20 are effectively connected and installed through multiple connecting rods 22, fastening nuts 25 and pins 26, ensuring that the side plates 20 on both sides are symmetrically arranged and that the first roller 21 and the second roller 23 on the side plates 20 on both sides rotate synchronously. Furthermore, the bottom of the two side plates 20 are fixedly installed by multiple connecting rods 22; each connecting rod 22 is provided with a fastening nut 25 at both ends; the fastening nut 25 is detachably installed to the connecting rod 22 by a pin 26; a hook 24 is fixedly installed on one of the connecting rods 22. In this embodiment, the first roller 21 and the second roller 23 are arranged perpendicularly to each other; wherein the second roller 23 is in contact with the sides of the single track 1. By adopting the above technical solution, during operation, when braking is required, the operator pulls the movable frame 33 outward, so that the movable frame 33 moves the arc plate 30 to fit against the surface of the first roller 21 through the fixed block and the pin, thereby increasing the friction between the first roller 21 and the movable arc plate 30 and ensuring the braking effect. The working principle of this utility model is as follows: During use, the top of the single track 1 is fixedly installed to the mine shaft, and the first roller 21 on the inner side of the side plate 20 of the running pulley assembly 2 contacts the top surface of the bottom support beam of the single track 1. At the same time, the second roller 23, which is movably installed at both ends of the side plate 20, contacts the side surface of the bottom support beam of the single track 1.

The connection between the hook 24 installed on the connecting rod 22 and the traction device effectively realizes the synchronous movement of the pulley assembly 2 and the braking structure 3. During operation, when braking is required, the operator pulls the movable frame 33 outward, so that the movable frame 33 moves the arc plate 30 to fit against the surface of the first roller 21 through the fixed block and the pin, thereby increasing the friction between the first roller 21 and the movable arc plate 30 and ensuring the braking effect.
