Description

Technical Field

[0001] This utility model relates to the technical field of monorail crane moving devices, and particularly to a pneumatic hydraulic monorail crane moving device. Background Technology

[0002] In material transportation in industrial sites such as mines and tunnels, monorail systems are often used to run on pre-set rails to complete tasks such as lifting and lateral movement. Typically, pneumatic hydraulic monorail moving devices are used. A pneumatic hydraulic monorail moving device is a rail transport equipment that uses compressed air as the driving power and hydraulic and mechanical mechanisms as the main braking methods. It completes the lifting and lateral movement of materials by running on pre-set rails.

[0003] In the prior art, when the device experiences a power outage or a power system failure during operation, the braking mechanism may fail to trigger effectively due to loss of power, or may rebound after braking due to the lack of a reliable locking mechanism, resulting in insufficient braking force and a risk of vehicle slippage.

[0004] Therefore, this application provides a pneumatic hydraulic monorail moving device to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pneumatic hydraulic monorail moving device to solve the problem mentioned in the background art that the braking mechanism cannot be effectively triggered when the power system fails during the operation of the device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pneumatic hydraulic monorail moving device includes a main body with a moving drive assembly. Braking assemblies are located at both the front and rear ends of the main body to restrict movement. Each braking assembly includes a base fixedly connected to one end of the main body. An active braking mechanism is mounted on the base, and a driven braking mechanism is located on one side of the base. The driven braking mechanism includes a connecting seat fixedly connected to the front end of the base. A rotating bracket is fixedly connected to the top of the connecting seat. Rotating rods are rotatably mounted at both ends of the rotating bracket. A counterweight is fixedly connected to one end of each rotating rod, and a multi-faceted brake plate is fixedly connected to the other end. A mounting bracket is fixedly connected to the front end of the connecting seat. A spring-reset actuator is fixedly connected to the mounting bracket. A support rod is fixedly connected to the output end of the spring-reset actuator. Rods are located at both ends of the support rod, and these rods are in contact with the counterweight. Limiting mechanisms are located at both ends of the rotating bracket.

[0007] Optionally, the limiting mechanism includes a turntable, which is fixedly connected to one side of the outer wall of the rotation center of the rotating rod, and a plurality of ratchet blocks are evenly arranged on the turntable along the circumference.

[0008] Optionally, the limiting mechanism further includes a fixed seat, which is fixedly connected to one end of the rotating bracket by fastening bolts.

[0009] Optionally, multiple housings are fixedly connected to the fixed base, the housings are arranged circumferentially along the fixed base, a pawl is rotatably mounted on the housing, and a spring is provided between the pawl and the housing.

[0010] Optionally, the base has two symmetrically formed rotating slots on its top and a moving cavity at its rear end.

[0011] Optionally, a hydraulic cylinder is provided in the movable cavity, and a spring is sleeved on the hydraulic cylinder. One end of the spring is fixedly connected to the outer shell of the hydraulic cylinder, and the other end is fixedly connected to the slide rod of the hydraulic cylinder.

[0012] Optionally, the active braking mechanism includes cranks, which are rotatably mounted in two rotating slots.

[0013] Optionally, one end of the crank is rotatably connected to the end of the hydraulic cylinder away from the slide rod, and the other end of the crank is rotatably connected to the slide rod of the hydraulic cylinder.

[0014] Optionally, a rotating seat is fixedly connected to the top center of the base, and multiple connecting rods are rotatably mounted on the rotating seat, with one end of each connecting rod hinged to a crank.

[0015] Optionally, each crank arm is fixedly connected to a fixing plate at the end away from the hydraulic cylinder, and a brake pad is fixedly connected to the fixing plate.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, a counterweight and a multi-faceted brake plate are used. When energized, a spring-reset actuator supports the counterweight, causing the brake plate to disengage from the rail. When power is off, the spring-reset actuator returns under the action of an internal reset spring, and the counterweight, under gravity, drives the rotating rod to rotate, bringing the multi-faceted brake plate into contact with the rail for emergency stopping. Simultaneously, a limiting mechanism, through the cooperation of a pawl and a ratchet block, forms a one-way lock, ensuring that after braking, the brake plate can only press against the rail and cannot rotate. By utilizing gravity as a power source, without relying on external electricity or hydraulic pressure, automatic braking is triggered in the event of a power outage or system failure, avoiding the risk of the device failing to stop due to power loss during ascent or descent. The one-way locking mechanism prevents accidental release after braking, ensuring the durability of emergency braking and thus improving the safety performance of the mobile device under abnormal operating conditions.

[0026] like Figures 1 to 5As shown, an embodiment of this utility model provides a pneumatic hydraulic monorail moving device, including a device body 1. A moving drive assembly 3 is provided on the device body 1. The moving drive assembly 3 enables the moving device to move on the monorail. The structure and working principle of the moving drive assembly 3 are existing technologies and will not be described in detail here. The moving drive assembly 3 is driven by a pneumatic motor and engages or contacts the monorail through gears, chains, or friction wheels to achieve the movement of the device on the monorail. The driving power source comes from external compressed air. The moving speed and direction are adjusted by a control valve. Braking assemblies 2 are provided at both the front and rear ends of the device body 1 to restrict the movement of the moving device. The braking assembly 2 includes a base... The base 21 is fixedly connected to one end of the main body 1 of the device. An active braking mechanism 22 is provided on the base 21 to facilitate active braking by the operator. A passive braking mechanism 23 is provided on one side of the base 21 to passively brake in the event of a power outage. The passive braking mechanism 23 includes a connecting seat 231, which is fixedly connected to the front end of the base 21. A rotating bracket 233 is fixedly connected to the top of the connecting seat 231. Rotating rods 234 are rotatably mounted at both ends of the rotating bracket 233. A counterweight 235 is fixedly connected to one end of each rotating rod 234, and a multi-faceted brake plate 236 is fixedly connected to the other end. The multi-faceted brake plate 236 is made of a high-friction material. Its multi-faceted design can adapt to different contours of the suspension rail, ensuring a large contact area and uniform braking force during braking. A mounting bracket 232 is fixedly connected to the front end of the connecting seat 231, and a spring return actuator 237 is fixedly connected to the mounting bracket 232. The spring return actuator 237 is existing technology, and its structure and working principle will not be described in detail here. A support rod 238 is fixedly connected to the output end of the spring return actuator 237. Rods are provided at both ends of the support rod 238, and the rods are in contact with the counterweight 235. Limiting mechanisms 26 are provided at both ends of the rotating bracket 233 to limit the rotation of the rotating rod 234. When energized, the spring return actuator 237 drives the support... When rod 238 moves upward, it supports counterweight 235. With counterweight 235 supported, multi-faceted brake plate 236 does not contact the suspension rail. When the moving device malfunctions and causes a power outage, spring reset actuator 237, under the action of its internal reset spring, drives support rod 238 to fall back, so that support rod 238 no longer supports counterweight 235. Under the action of gravity, counterweight 235 drives rotating rod 234 to rotate. Under the action of gravity, counterweight 235 rotates around the axis of rotating rod 234, thereby causing multi-faceted brake plate 236 to contact the suspension rail, thus enabling emergency stop and preventing the device from failing to stop during descent or ascent.

[0027] like Figure 5As shown, the limiting mechanism 26 includes a turntable 261, which is fixedly connected to one side of the outer wall of the rotation center of the rotating rod 234. A plurality of ratchet blocks 262 are evenly arranged circumferentially on the turntable 261. The limiting mechanism 26 also includes a fixed seat 263, which is fixedly connected to one end of the rotating bracket 233 by fastening bolts 264. A plurality of housings 265 are fixedly connected to the fixed seat 263, arranged circumferentially. Pawls 266 are rotatably mounted on the housings 265, and springs 267 are provided between the pawls 266 and the housings 265. During the rotation of 34, the turntable 261 will rotate synchronously. Under the elastic force of the second spring 267, the pawl 266 will always press against the ratchet block 262 of the turntable 261, forming a one-way lock. In the braking state, the turntable 261 can only rotate in the braking direction with the rotating rod 234, so that the multi-faceted brake plate 236 presses against the hanging rail and cannot rotate in the opposite direction. When manually releasing, the fastening bolt 264 must be removed first to take off the fixing seat 263, so that the pawl 266 disengages from the ratchet block 262. Then the rotating rod 234 or the multi-faceted brake plate 236 can be manually rotated to disengage from the hanging rail, or the spring reset actuator 237 can be re-energized to make the support rod 238 rise and reset.

[0028] like Figure 3As shown, the base 21 has two symmetrically arranged rotating slots 24 on its top, and a moving cavity 25 is provided at its rear end. A hydraulic cylinder 221 is installed in the moving cavity 25, and a spring 227 is fitted onto the hydraulic cylinder 221. One end of the spring 227 is fixedly connected to the outer shell of the hydraulic cylinder 221, and the other end is fixedly connected to the slide rod of the hydraulic cylinder 221. The active braking mechanism 22 includes cranks 222, which are rotatably mounted in the two rotating slots 24. One end of the crank 222 is rotatably connected to the end of the hydraulic cylinder 221 away from the slide rod, and the other end... The end of crank 222 is rotatably connected to the slide rod of hydraulic cylinder 221. A fixing plate 223 is fixedly connected to the end of each crank 222 away from hydraulic cylinder 221, and a brake pad 224 is fixedly connected to the fixing plate 223. A rotating seat 226 is fixedly connected to the top center of the base 21. Multiple connecting rods 225 are rotatably mounted on the rotating seat 226. One end of each connecting rod 225 is hinged to the crank 222, and the other end is hinged to the middle or end of the crank 222, forming a parallel four-bar linkage. This ensures that the two cranks 222 move synchronously, prevents the brake pad 224 from deflecting, and improves stability. High braking stability; when active braking is required, the hydraulic cylinder 221 is controlled to drive the two cranks 222 to rotate. When the slide rod of the hydraulic cylinder 221 extends or retracts, it pushes the two cranks 222 to rotate around their axis in the rotation groove 24. The two cranks 222 rotate synchronously, causing the brake pads 224 to clamp the suspension rail, thereby making the brake pads 224 contact the suspension rail to achieve braking. Spring 227 is a compression spring, whose function is to keep the cranks 222 in the default position when the hydraulic cylinder 221 is not working, and to provide buffering during hydraulic action to avoid excessive braking. When 21 contracts, spring 227 assists the slide bar to reset, improving the system response speed. The active braking mechanism 22 and the driven braking mechanism 23 work independently, but share the same base 21. During normal operation, the active braking mechanism 22 is in the released state, and the driven braking mechanism 23 is supported by the counterweight 235 by the spring reset actuator 237. The brake plate is disengaged from the hanging rail. When active braking is required, the hydraulic cylinder 221 is activated to achieve braking. When there is a power failure or malfunction, the driven braking mechanism 23 automatically triggers emergency braking. The two do not interfere with each other, but the driven braking needs to be manually reset before the device can move again.

[0029] The working principle of the technical solution provided by this utility model is as follows: The main body 1 of the device moves on the hanging rail via a moving drive assembly 3. The moving drive assembly 3 is driven by a pneumatic motor and moves by meshing or contacting the hanging rail through gears, chains, or friction wheels. The driving power source comes from external compressed air. The moving speed and direction are adjusted by a control valve. During normal movement, the braking assembly 2 is in a released state and does not interfere with the movement. When the operator needs to actively stop, it is achieved by controlling the active braking mechanism 22. The hydraulic cylinder 221 is controlled to move, and the slide rod of the hydraulic cylinder 221 extends and retracts, pushing two cranks 222 to rotate around the axis in the rotating groove 24. The cranks 222 drive the fixed plate 223 and the brake pad 224 to clamp the hanging rail, thereby achieving braking.

[0030] When the mobile device malfunctions or loses power, the driven braking mechanism 23 automatically triggers emergency braking. Under normal power conditions, the output end of the spring reset actuator 237 drives the support rod 238 to move upward. The rod of the support rod 238 supports the counterweight 235, causing the multi-faceted brake plate 236 to disengage from the hanging rail, allowing the device to move freely. When power is lost, the reset spring inside the spring reset actuator 237 causes the support rod 238 to fall back. The support rod 238 no longer supports the counterweight 235. Under the action of gravity, the counterweight 235 drives the rotating rod 234 to rotate around the axis of the rotating bracket 233, causing the multi-faceted brake plate 236 to contact the hanging rail, achieving an emergency stop. When the rotating rod 234 rotates, the turntable 261 rotates synchronously. The pawl 266 presses against the ratchet block 262 under the elastic force of the spring 267, forming a one-way lock, so that the turntable 261 can only rotate in the braking direction. After the multi-faceted brake plate 236 presses against the hanging rail, it cannot rotate in the opposite direction.

[0031] After braking, the active braking mechanism 22 resets by controlling the hydraulic cylinder 221, and the spring 227 assists the crank 222 to return to the default position, and the brake pad 224 disengages from the rail. The driven braking mechanism 23 needs to be manually reset after emergency braking. First, remove the fastening bolt 264 to remove the fixing seat 263, so that the pawl 266 disengages from the ratchet block 262. Then, manually rotate the rotating rod 234 or the multi-faceted brake plate 236 to disengage from the rail, or re-energize the spring reset actuator 237 to raise and reset the support rod 238, and re-support the counterweight block 235.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0033] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
