Description

Technical Field

[0001] This application relates to the field of rail hoisting technology, and in particular to an auxiliary rail lifting device for monorail laying. Background Technology

[0002] A monorail is a device that runs on a suspended monorail. It consists of a specially made I-beam suspended above the tunnel as the rail, and various types of gantry cranes connected together, which are pulled along the rail by traction equipment.

[0003] Monorail cranes are a type of specialized transportation equipment commonly used in heavy industrial production, especially in mines. During the installation of a monorail, the track needs to be lifted section by section to a designated height, then fixed to the lifting points, and finally connected to form a complete track. Currently, the lifting and installation of the track is mainly done manually, requiring at least four people to lift a single track. This manual installation method is not only time-consuming, labor-intensive, and costly, but also poses significant safety risks. Summary of the Invention

[0004] This utility model aims to provide an auxiliary rail lifting device for monorail laying. This device can significantly reduce the labor intensity of monorail laying work, reduce personnel input, improve laying efficiency, and ensure personnel safety. It is achieved through the following technical solution.

[0005] A monorail installation auxiliary rail lifting device includes a support frame, a power unit, and a lifting device. The support frame consists of a base frame and an upright frame. The base frame is horizontally arranged, and one end of the upright frame is vertically connected to one end of the base frame, forming an L-shaped support structure. The power unit includes a pulley block, a steel cable, and a hand-cranked winch. The steel cable is wound around the pulley block, with one end connected to the hand-cranked winch and the other end connected to the lifting device. A slide rail is provided on the inner side of the upright frame, and the lifting device is slidably mounted on the slide rail on the inner side of the upright frame. The pulley block includes a fixed pulley block, a movable pulley, and a slider. The fixed pulley block is located on the upper part of the upright frame, the movable pulley is located above the lifting device, and the slider is located on the lower part of the upright frame.

[0006] Preferably, the ratio of the height of the upright to the width of the base frame is less than 3:2.

[0007] Preferably, the base frame is fixedly connected to the upright frame on both sides by inclined square tubes.

[0008] Preferably, the lower part of the support frame is provided with a first square tube, and the upper part is provided with a second square tube, and the first square tube and the second square tube are fixedly connected to the support frame.

[0009] Preferably, the first and second square tubes are U-shaped, with their ends fixed to both sides of the upright frame.

[0010] Preferably, the fixed pulley group includes a first fixed pulley, a second fixed pulley, and a third fixed pulley, with the three fixed pulleys respectively fixed on the second square tube and the upright.

[0011] Preferably, the hand-cranked winch is fixed on the first square tube, and a support rod is provided below the first square tube, with a slider fixedly connected to the support rod.

[0012] Preferably, the lifting device is positioned above the connection point between the oblique tube and the upright, and the steel cable connects the lifting device to the side of the upright.

[0013] Preferably, a baffle is provided on the side of the lifting device away from the upright, and limiting blocks are symmetrically provided on the side of the lifting device near the upright.

[0014] Preferably, the limiting block is slidably connected to the lifting device and consists of a slider and a buckle. The buckle is equipped with a locking device. After the buckle is engaged with the slide rail, the locking device can be rotated to lock it onto the slide rail.

[0015] The monorail laying auxiliary rail lifting device of this utility model has the following beneficial effects:

[0016] 1. Due to the use of pulley transmission and the use of slide rails, the rail can be lifted with less force, which not only saves time and effort and reduces workload, but also reduces the number of workers, lowers the cost of rail laying, and improves the efficiency of monorail laying.

[0017] 2. The ratio of the height of the upright frame to the width of the base frame should be less than 3:2. This design ensures that even when supporting heavy objects, the support will not become unbalanced. Furthermore, the use of rhomboid tubing enhances the stability and load-bearing capacity of the support system.

[0018] 3. Because a square tube is installed on one side of the support frame, the square tube can not only be used for fixing, but also enhance the strength of the entire device. At the same time, it can also protect the workers who are operating the winch, preventing them from being injured.

[0019] 4. A limit block is installed at the bottom of the lifting device. When the lifting device is pulled to the desired stopping position, the limit block slides to the slide rail and engages with it, thus limiting its position. A baffle is also installed on the other side of the lifting device to prevent the rail from falling off and causing a safety accident, thereby improving the overall safety of the device.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1-2 As shown, the monorail hoisting auxiliary rail lifting device of this utility model includes a support, a power unit, and a lifting device 7. The support consists of a base frame 9 and a vertical frame 5. The base frame 9 is arranged horizontally, and one end of the vertical frame 5 is vertically connected to one end of the base frame 9, forming an L-shaped support structure. The power unit includes a pulley block, a steel cable 15, and a hand-cranked winch 14. The steel cable 15 is wound on the pulley block, and one end of the steel cable 15 is connected to the hand-cranked winch 14, while the other end is connected to the lifting device 7. A slide rail is provided on the inner side of the vertical frame 5, and the lifting device 7 is slidably mounted on the slide rail on the inner side of the vertical frame 5. The pulley block includes a fixed pulley block, a movable pulley, and a slider 11. The fixed pulley block is located on the upper part of the vertical frame 5, the movable pulley is located above the lifting device 7, and the slider 11 is located on the lower part of the vertical frame 5.

[0032] To enhance the overall stability of the lifting device and prevent it from tipping over, the height ratio of the upright 5 to the width ratio of the base frame 9 is set to less than 3:2. This prevents it from tipping over due to being top-heavy, and ensures that the support will not become unbalanced even if the object being lifted is heavy.

[0033] To further enhance the overall stability of the rail lifting device, the base frame 9 is fixedly connected to the upright frame 5 on both sides by inclined square tubes 8. These square tubes can firmly fix the base frame 9 and the upright frame 5 into a whole, thereby enhancing the stability and pressure resistance of the support.

[0034] The support frame 5 has a first square tube 13 at its lower part and a second square tube 16 at its upper part, and the first square tube 13 and the second square tube 16 are fixedly connected to the support frame 5. In one embodiment, the first square tube 13 and the second square tube 16 can be respectively set at a distance of one-quarter from the ground and a distance of one-quarter from the top of the support frame 5.

[0035] The first square tube 13 and the second square tube 16 are U-shaped, and their two ends are fixed to the two sides of the upright 5 respectively. This arrangement can not only balance the torque, but also provide workers with a certain safe operating space and reduce the probability of safety accidents.

[0036] The fixed pulley assembly includes a first fixed pulley 1, a second fixed pulley 2, and a third fixed pulley 3, which are respectively fixed to the second square tube 16 and the upright frame 5. Since the upright frame 5 is equipped with a U-shaped square tube, the three fixed pulleys can be fixed to the upright frame 5 and the second square tube 16 respectively, thereby achieving transmission.

[0037] The hand-cranked winch 14 is fixed on the first square tube 13 located at the lower part of the upright 5. This arrangement facilitates operation by the staff. A support rod 12 is provided below the first square tube 13. A slider 11 is fixedly connected to the support rod 12. The slider 11 functions similarly to a fixed pulley, allowing the steel cable to pass through again through the fixed pulley located above.

[0038] The lifting device 7 is positioned above the connection point between the oblique tube 8 and the upright frame 5, and the steel cable 15 connects the lifting device 7 to the side of the upright frame 5.

[0039] To prevent the track from detaching from the lifting device 7 during use, a baffle 6 is installed on the side of the lifting device 7 away from the upright 5. The baffle 6 prevents the track from falling off. In addition, symmetrical limiting blocks 10 are installed below the lifting device 7 on the side near the upright 5. When the lifting device 7 is pulled to the position to stop, the limiting blocks 10 slide to the slide rail and engage with it to help limit the position of the traction device. When it is necessary to shake the winch to raise or lower the lifting device 7, the limiting blocks 10 slide away from the slide rail.

[0040] Working process: First, lower the lifting device to its lowest position by cranking the hand winch, then lock the limit block into the slide rail for fixation. Next, place the track onto the lifting device, then remove the limit block. Then, crank the hand winch again. Through the cooperation of the fixed pulley, movable pulley, slider, and slide rail, the lifting device can be easily raised to the required height. Finally, lock the limit block into the slide rail for fixation, thus securing it to the lifting point.
