Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a crane wheel sliding mechanism with an emergency stop limit. Background Art

[0002] Single-beam bridge crane is a lifting equipment that is horizontally mounted above workshops, warehouses and material yards to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of the single-beam bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, and can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and largest type of lifting machinery, and the wheel pulley mechanism is required for the movement of the single-beam bridge crane.

[0003] However, during the use of the existing crane wheel sliding mechanism, the crane wheel sliding mechanism needs to move back and forth on the crossbar track. When the crane wheel sliding mechanism moves to the edge, the crane wheel sliding mechanism has a certain sliding distance, and the crane wheel sliding mechanism cannot perform buffering and emergency stop. As a result, the crane wheel sliding mechanism will collide with the wall when moving to the edge, causing the crane wheel sliding mechanism to be easily damaged by collision. For this reason, we propose a crane wheel sliding mechanism with emergency stop limit. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a crane wheel sliding mechanism with an emergency stop limit function to solve the problems raised in the above-mentioned background technology.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a crane wheel pulley mechanism with an emergency stop limit comprises a sliding rod, buffer openings are provided on both sides of the sliding rod, buffer rods are movably connected to both sides of the sliding rod through the buffer openings, a buffer pad is fixedly connected to one end of the buffer rod, a buffer spring is movably connected to the outside of the buffer rod, an emergency stop switch is fixedly connected to the inside of the sliding rod, a driving mechanism is fixedly connected to the top of the sliding rod, a wheel pulley frame is fixedly connected to the bottom of the sliding rod, a connecting shaft is movably connected through the front of the wheel pulley frame, a transmission wheel is fixedly connected to one end of the connecting shaft, and a pulley is fixedly connected to the inside of the wheel pulley frame through the connecting shaft.

[0008] Preferably, the driving mechanism includes a driving motor, a driving wheel and a transmission belt, the driving motor is fixedly connected to the top of the sliding rod, the driving end of the driving motor is fixedly connected to the driving wheel, the outer side of the driving wheel is movably connected to the transmission belt, and the transmission belt is movably connected to the transmission wheel.

[0009] Preferably, the front and back sides of the sliding rod are fixedly connected with protective frames, and two protective frames are provided, and the two protective frames are symmetrically arranged.

[0010] Preferably, the diameter of the buffer rod is matched with the inner diameter of the buffer port, and the buffer rod is movably connected to the buffer port.

[0011] Preferably, the buffer pad is made of rubber material and has a solid structure.

[0012] Preferably, the sliding rod is made of carbon steel material, and the outer surface of the sliding rod is smooth.

[0013] (III) Beneficial effects

[0014] The utility model provides a crane wheel sliding mechanism with emergency stop limit, which has the following beneficial effects:

[0015] (1) The crane wheel skating mechanism with emergency stop limit is provided with an emergency stop switch, a buffer rod, a buffer spring and a buffer pad. When the crane wheel skating mechanism is used, the pulley is installed on the slide rail so that the protective frame wraps the outer side of the slide rail. When the crane wheel skating mechanism needs to move, the driving motor drives the transmission belt to rotate through the driving wheel, and the transmission belt drives the connecting shaft to rotate through the driving wheel, and the pulley drives the connecting shaft to rotate. At this time, the crane wheel skating mechanism can move. When the crane wheel skating mechanism moves to the edge, the buffer pad will contact the wall, and the thrust acting on the buffer pad will squeeze the buffer rod. At this time, the buffer rod will shrink to the buffer opening, and the buffer spring will shrink. At this time, the buffer spring uses its own properties to play a buffering role. When the impact force is too large, the buffer rod will squeeze the emergency stop switch. At this time, the emergency stop switch will directly lock the driving motor, so that the pulley plays a brake role, so that the crane wheel skating mechanism has a buffering emergency stop function, and avoids the crane wheel skating mechanism from colliding with the wall when moving to the edge.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] In this embodiment, specifically, the driving mechanism includes a driving motor 10, a driving wheel 11 and a transmission belt 12. The driving motor 10 is fixedly connected to the top of the sliding rod 1, and the driving end of the driving motor 10 is fixedly connected to the driving wheel 11. The outer side of the driving wheel 11 is movably connected to the transmission belt 12. The transmission belt 12 is movably connected to the transmission wheel 8. The driving motor 10 drives the transmission belt 12 to operate through the driving wheel 11, and the transmission belt 12 drives the connecting shaft 6 to rotate through the transmission wheel 8, and the pulley 7 will drive the connecting shaft 6 to rotate, and then the crane wheel pulley mechanism can move.

[0024] In this embodiment, specifically, the front and back sides of the sliding rod 1 are fixedly connected with protective frames 9, and two protective frames 9 are provided, and the two protective frames 9 are symmetrically arranged. Through the protective frames 9, the crane wheel sliding mechanism can be firmly installed on the slide rail.

[0025] In this embodiment, specifically, the diameter of the buffer rod 2 is matched with the inner diameter of the buffer port 101, and the buffer rod 2 is movably connected to the buffer port 101, so that the buffer rod 2 can play a role of relieving force by contracting into the buffer port 101, thereby achieving the purpose of buffering.

[0026] In this embodiment, specifically, the buffer pad 4 is made of rubber material, and the buffer pad 4 is a solid structure. The buffer pad 4 made of rubber material can play a buffering role by utilizing the properties of the material itself.

When using the crane wheel skating mechanism, install the pulley 7 on the slide rail so that the protective frame 9 wraps the outer side of the slide rail.

At this time, the buffer rod 2 will shrink to the buffer port 101, and the buffer spring 3 will shrink. At this time, the buffer spring 3 uses its own properties to play a buffering role. When the impact force is too large, the buffer rod 2 will squeeze the emergency stop switch 102.
