Description

Technical Field

[0001] The utility model relates to the technical field of gantry cranes, in particular to a gantry crane trolley horizontal wheel anti-falling device. Background Art

[0002] Gantry crane is a variation of bridge crane, also called portal crane, which is mainly used for loading and unloading operations in cargo yards, material yards and bulk cargo. Gantry crane has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. It is widely used in port cargo yards, but its horizontal wheels often fall when lifting goods, which can easily cause safety hazards, and thus a gantry crane trolley horizontal wheel anti-fall device is needed.

[0003] The horizontal wheel anti-fall device of the gantry crane trolley is usually installed at the front end of the running end beam. It relies on the horizontal wheels on both sides of the running track to limit the tendency of the crane trolley wheels to bite the track. Before the trolley wheels rub the track, they first contact the track in a rolling manner to offset the horizontal lateral force of the trolley running part and prevent the track from being bitten. At the same time, the installation position of the two horizontal wheels is lower than the track plane and the wheel edge, which is equivalent to maximizing the height of the wheel edge. Prevent crane derailment accidents caused by the original wheel edge being too shallow.

[0004] However, the existing anti-fall devices are prone to vibration and loosening during operation, which may lead to a deterioration in the anti-fall effect or even loss of its function. At the same time, the functions are relatively single. When moving, the gantry crane often vibrates, which affects work efficiency and brings certain production risks. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 6 The utility model provides an embodiment: a gantry crane trolley horizontal wheel anti-fall device, including a crossbeam 1, a groove 11 is opened inside the crossbeam 1, a support frame 25 is fixedly connected to the lower surface of the crossbeam 1, a bottom plate 10 is arranged below the support frame 25, a shock-absorbing pad 9 is fixedly connected to the upper surface of the bottom plate 10, an electric slide rail 28 is fixedly connected to the upper surface of the shock-absorbing pad 9, a roller 7 is fixedly connected to the output end of the electric slide rail 28, and the outer wall of the roller 7 is rotatably connected to the bottom of the support frame 25.

[0027] Specifically, by providing the groove 11 inside the crossbeam 1, when the pulley 12 rolls on the inner wall of the special-shaped slide rail 2, the connecting rod 26 rotatably connected to its lower surface can pass through the groove 11, thereby enabling the goods to be lifted at a higher height; by starting the electric slide rail 28, the output end of the electric slide rail 28 drives the roller 7 to slide inside the electric slide rail 28, so that the lifted goods can be transported longitudinally, thereby improving the practicality of the device; at the same time, when the roller 7 rolls, the lower end surface of the electric slide rail 28 is squeezed and contacted with the upper end surface of the shock-absorbing pad 9, which can better reduce the vibration of the gantry crane, thereby improving the stability of the gantry crane and ensuring a safe working environment.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the crossbeam 1 is fixedly connected to an electric slide rail 3, the output end of the electric slide rail 3 is fixedly connected to a slider 6, the outer wall of the slider 6 is fixedly connected to a protective shell 5, the upper surface of the crossbeam 1 is fixedly connected to a special-shaped slide rail 2, the inner wall of the special-shaped slide rail 2 is slidably connected to a pulley 12, the lower surface of the pulley 12 is rotatably connected to a connecting rod 26, the lower surface of the connecting rod 26 is fixedly connected to an electric push rod 14, the output end of the electric push rod 14 is fixedly connected to a counterweight block 15, and the lower surface of the counterweight block 15 is fixedly connected to a hook 16.

[0029] Specifically, by providing the special-shaped slide rail 2, the pulley 12 can be conveniently rolled on the inner wall of the special-shaped slide rail 2, thereby driving the movement of the goods below to realize horizontal transportation. By cooperating with the electric slide rail 2 8 and the roller 7, the lifted goods can be transported longitudinally; the practicality of the device is further improved; by starting the electric push rod 14, its output end pushes the counterweight block 15 and the hook 16 to move, so that the goods can be adjusted to different heights; the counterweight block 15 provides a center of gravity for lifting, preventing the goods connected to the hook 16 from shaking due to environmental influences such as strong winds and causing overturning and falling, thereby improving the stability of lifting and transportation.

[0030] Reference Figure 3 , Figure 4 and Figure 5A transverse bearing 13 is rotatably connected to one side of the outer wall of the pulley 12, and a rotating assembly 4 is arranged on the other side of the outer wall of the pulley 12. The rotating assembly 4 includes a copper sleeve 24 and a main shaft 20. The outer wall of the copper sleeve 24 is fixedly connected to the outer wall of the pulley 12, one end of the main shaft 20 is fixedly connected to one side of the outer wall of the pulley 12, and the other end of the main shaft 20 is rotatably connected to the reducer 19, and the outer wall of the main shaft 20 is fixedly connected to a flange 21. The outer wall of the main shaft 20 is rotatably connected to a pressure bearing 22, and a load-bearing bearing 23 is arranged on one side of the pressure bearing 22. The inner wall of the load-bearing bearing 23 is rotatably connected to the outer wall of the main shaft 20, and the outer wall of the load-bearing bearing 23 is rotatably connected to the inner wall of the copper sleeve 24, and the outer wall of the reducer 19 is rotatably connected to the rotating shaft 18. A motor 17 is arranged on one side of the outer wall of the reducer 19, and the output end of the motor 17 is connected to the rotating shaft 18. The outer wall of the motor 17 is fixedly connected to the inner wall of the protective shell 5.

[0031] Specifically, by starting the motor 17, its output end drives the rotating shaft 18 to rotate, and the speed is adjusted by the reducer 19. The reducer 19 can prevent the motor 17 from driving the rotating shaft 18 to rotate too fast, thereby making the cargo transportation unstable and easily causing safety accidents, so that the speed tends to be stable, and the cargo can be transported smoothly; the reducer 19 transmits the rotation speed to the main shaft 20, so that the main shaft 20 rotates, thereby rotating the pressure bearing 22 sleeved on its surface, driving the load-bearing bearing 23 to rotate inside the copper sleeve 24, and then the pulley 12 starts to rotate to transport the cargo; the original eccentric sleeve structure of the pulley 12 is replaced with the copper sleeve 24 structure, and the load-bearing bearing 23, the pressure bearing 22 and the transverse bearing 13 are added to avoid the vibration and loosening of the device during operation, so that the rotation of the pulley 12 is more stable.

[0032] Working principle: When it is necessary to use the gantry crane to lift the goods, the electric push rod 14 under the connecting rod 26 is started by installing a controller, so that its output end pushes the counterweight 15 and the hook 16 to move downward. When the appropriate height is reached, the hook 16 is hung on the goods and fixed firmly. At this time, the controller is adjusted to start the motor 17 in the protective shell 5, so that its output end drives the rotating shaft 18 to rotate, and the speed is adjusted by the reducer 19, and then transmitted to the main shaft 20 of the rotating component 4. The main shaft 20 rotates, and then the flange 21 on its surface rotates with it. At the same time, the pressure bearing 22 set on its surface rotates, driving the load-bearing bearing 23 to rotate in the copper sleeve 24, and then the pulley 12 starts to rotate. Under the rotation adjustment of the transverse bearing 13, the pulley 12 drives the goods below to start rolling in the special-shaped slide rail 2, and at the same time, the electric slide rail 3 is started, and its output end drives the slider 6 to slide inside it, thereby driving the protective shell 5 to transport the goods horizontally without vibration and loosening.

[0033] In addition, when the goods need to be transported longitudinally, the electric slide rail 2 8 is started by adjusting the controller, so that its output end drives the roller 7 to slide inside the electric slide rail 2 8, and then drives the beam 1 and the goods it lifts through the support frame 25.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
