Description

Technical Field

[0001] The utility model relates to the technical field of simulation of dangerous accident equipment, in particular to a simulation device for hoisting fall accidents. Background Art

[0002] In daily construction operations, high-altitude hoisting operations are a high-risk job. Hoisting operations refer to the process of using various hoisting tools to lift equipment, workpieces, utensils, materials, etc. during inspection and maintenance, causing their position changes.

[0003] Some common or potential major risks during hoisting operations, such as sling breakage, overloading, unhooking, slipping, etc. High-altitude fall accidents often pose a serious threat to the lives and physical health of workers. In order to be able to respond to high-altitude fall accidents in a timely and effective manner and minimize losses during accidents to the greatest extent, it is necessary to conduct emergency drills for heavy object high-altitude fall accidents. During the process of conducting emergency drills for heavy object high-altitude fall accidents, the heavy object is made to fall off the sling. In the prior art, the operation and triggering of the unhooking device are usually carried out manually.

[0004] However, in actual use, ordinary slings do not have unhooking devices, and at this time, the unhooking action cannot be carried out by using the unhooking device. Moreover, when using the manual triggering of the unhooking device, because manual operations are prone to errors, phenomena such as the flying out of connecting objects and the breaking of ropes are likely to occur during actual use, which ultimately easily causes harm to the personal safety of the operator. In addition, the entire operation process takes a long time and is complex, which is not conducive to the efficient progress of emergency drills. Summary of the Utility Model

[0005] The utility model aims at the problems in the prior art and provides a simulation device for hoisting fall accidents with remote control, which solves the problem of difficult manual unhooking in the prior art.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A simulation device for hoisting fall accidents, including a main body. Inside the main body, a wireless control module and a power supply are arranged. The power supply is electrically connected to the wireless control module. A top hook is fixedly installed on the main body, and the top hook is used to connect with a hoisting tool. A servo motor is also arranged at the lower end of the main body. The wireless control module is electrically connected to the servo motor to control the servo motor. A first connecting plate and a second connecting plate are also arranged at the lower end of the main body. A first through hole is arranged on the first connecting plate, and a second through hole is arranged on the second connecting plate. The device also includes a release shaft. One end of the release shaft is connected to the servo motor, and the other end of the release shaft can pass through the first through hole and the second through hole. The release shaft is used to restrict and release a heavy object. By setting the wireless control module and the servo motor, it is possible to remotely control the rotation of the servo motor by personnel to complete the release of the heavy object, without the need for manual unhooking operations, reducing the risk of harm to the personal safety of operators. Moreover, the entire operation process is short and the operation is simple, which is beneficial to the efficient progress of emergency drills.

[0008] Preferably, at least one driving roller is arranged at the upper end of the release shaft. The axis direction of the driving roller is perpendicular to the axis direction of the release shaft, and the driving roller is used to abut against the heavy object. By arranging the driving roller on the release shaft, the sliding friction between the release shaft and the heavy object during the movement of the release shaft is changed into the rolling friction between the driving roller and the release shaft, greatly reducing the frictional force, thereby reducing the load of the servo motor and extending the service life of the equipment.

[0009] Preferably, two groups of driving rollers are symmetrically arranged on the circumferential surface of the release shaft. By symmetrically arranging two groups of driving rollers on the release shaft, after one group of driving rollers is damaged, the position of the release shaft can be adjusted to switch to the second group of driving rollers to contact the heavy object, extending the service life of the release shaft and reducing the use cost of the equipment.

[0010] Preferably, it also includes a first connecting rod and a second connecting rod. One end of the first connecting rod is connected to the output shaft of the servo motor, the other end of the first connecting rod is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to one end of the release shaft. By arranging the first connecting rod and the second connecting rod, when the servo motor moves, the release shaft can always move along the axis direction, reducing the friction between the release shaft and the first through hole and the second through hole.

[0011] Preferably, the upper end of the main body includes an upper cover. The upper cover is fixedly arranged on the outer shell, and the top hook is fixedly installed on the upper cover. By arranging the upper cover, the power supply, wireless control module and other mechanisms inside the main body can be protected.

[0012] Preferably, the upper cover is connected to the main body through symmetrically arranged bolts. By connecting the upper cover and the main body with bolts, the upper cover can be removed by unscrewing the bolts on the premise of ensuring a firm connection, which is convenient for maintaining the internal structure of the main body.

[0013] As can be seen from the above technical solutions, the advantages of the present utility model are as follows: By providing the wireless control module and the servo motor, it is possible to remotely control the rotation of the servo motor by personnel to complete the release of heavy objects, eliminating the need for manual unhooking operations, reducing the risk of harm to the personal safety of operators, and the entire operation process is short and the operation is simple, which is conducive to the efficient conduct of emergency drills. By providing the transmission roller on the release shaft, the sliding friction between the release shaft and the heavy object during the movement of the release shaft is converted into the rolling friction between the transmission roller and the release shaft, greatly reducing the frictional force, thereby reducing the load on the servo motor and extending the service life of the equipment. By symmetrically providing two sets of transmission rollers on the release shaft, after one set of transmission rollers is damaged, the position of the release shaft can be adjusted to switch to the second set of transmission rollers to contact the heavy object, extending the service life of the release shaft and reducing the use cost of the equipment. By providing the first connecting rod and the second connecting rod, when the servo motor moves, the release shaft can always move along the axial direction, reducing the friction between the release shaft and the first through hole and the second through hole. By providing the upper cover, it is possible to protect the power supply, wireless control module and other mechanisms inside the body. The upper cover is connected to the body by bolts, and on the premise of ensuring a firm connection, the upper cover can be removed by unscrewing the bolts, which is convenient for maintaining the internal structure of the body.
