Description

Technical Field

[0001] The utility model relates to the technical field of crane rails, in particular to an aluminum alloy rail system of a crane. Background Art

[0002] A crane refers to a multi-action lifting machinery that vertically lifts and horizontally carries heavy objects within a certain range. In a factory building, a bridge crane is generally used to lift and transfer heavy objects. When the crane is in use, it uses contact friction through its own moving wheels to move along the aluminum alloy track. Among the components of the crane, the crane track system plays a very important role in carrying the crane for safe transportation. When the aluminum alloy track system of some cranes is erected, first align the two sections of aluminum alloy guide rails longitudinally, and then heat-melt the contact surfaces between the two aluminum alloy guide rails together by spot welding to achieve connection. The remaining aluminum alloy guide rails are connected by the same principle, and then the aluminum alloy track system is erected and fixed to the designated position above the factory building through the mounting seat. Then the moving wheel of the crane is stuck in the track of the aluminum alloy guide rail, and the crane is moved by the contact friction of the erected aluminum alloy track system. However, when the aluminum alloy track system is erected and connected, welding is used to completely heat-melt the edge of the contact surface of the guide rail to be connected and cool it, which is inefficient, and the aluminum alloy track system cannot be disassembled later, resulting in a waste of resources.

In this process, the airbag shock absorber uses air pressure resistance to absorb the vibration force generated by the moving wheel during the operation of the crane, thereby improving the operation stability of the crane. The airbag shock absorber is a sealed air spring filled with compressed gas, and uses the compressibility of the gas to achieve its spring effect. The airbag uses a height adjustment valve to control the air pressure in the bag to make the stiffness of the air spring adjustable. When the load of the moving guide seat acting on the spring increases, the air pressure increases, and the stiffness of the spring increases. Conversely, when the load of the moving guide seat decreases, the air pressure in the spring decreases and the stiffness decreases. The shock absorption effect is achieved through gas compression and release. The aluminum alloy track system of the crane absorbs the vibration force generated by the crane moving along the track system through air pressure resistance, thereby improving the movement stability of the crane.

The left and right sides of the aluminum alloy guide rail 1 are provided with evenly distributed offset baffles 16. The side of the offset baffle 16 close to the center of the aluminum alloy guide rail 1 is provided with a limit strip 17. The lower side of the limit strip 17 is in contact with the upper side of the adjacent mobile guide seat 15. The front and rear sides of the mobile guide seat 15 are provided with synchronization slots 18, and the synchronization slots 18 are plugged with synchronization sockets 19. When assembling and erecting the aluminum alloy rail system of the crane, first insert the corresponding guide sockets 13 and synchronization sockets 19 into the guide slots 12 and synchronization slots 18 at the front end of the initial aluminum alloy guide rail 1, and then insert the rear end of another aluminum alloy guide rail 1 The ends are assembled and connected with the initial aluminum alloy guide rails 1 through the corresponding guide sockets 13 and the synchronous sockets 19, so as to limit the vertical plane movement between the two aluminum alloy guide rails 1, and then the H-shaped card block 9 is inserted into the adjacent T-shaped card slots 3 between the two aluminum alloy guide rails 1, so as to limit the longitudinal movement between the two aluminum alloy guide rails 1, and then the dial button 8 is pulled to drive the rectangular card block 7 to move along the corresponding avoidance groove 11 to the outside of the H-shaped card block 9, and the spring 6 is elastically stretched, and then the dial button 8 is rotated to drive the rectangular card block 7 to rotate to be vertically aligned with the adjacent card slot 10, and then the force applied to the dial button 8 by the card feeding makes the rectangular card block 7 engage with the adjacent card slot 10 through the stretching elastic force of the spring 6, so as to limit the vertical movement of the H-shaped card block 9, and then The two aluminum alloy guide rails 1 are quickly assembled, and the connection operation is convenient during the erection of the aluminum alloy track system. The remaining aluminum alloy guide rails 1 are then assembled and connected in sequence through the same principle, and the aluminum alloy track system can be disassembled and reused later. The device is then fixed to the specified position with bolts through the mounting seat 2, and the moving wheels of the crane are then respectively inserted between the two vertically adjacent moving guide seats 15. The contact friction between the moving wheels and the moving guide seats 15 allows the crane to move along the aluminum alloy track system. The plug-in relationship between the synchronous socket 19 and the synchronous slot 18 allows the moving guide seats 15 to be subjected to force synchronously, thereby avoiding height differences between the moving guide seats 15 due to different compression and shock absorption contraction of the airbag shock absorber 14.By offsetting the baffle plate 16, the movable wheel of the crane is laterally offset and limited.

The air bag shock absorber 14 is a sealed air spring filled with compressed gas, and uses the compressibility of the gas to achieve its spring effect. The air bag uses a height adjustment valve to control the air pressure in the bag to make the stiffness of the air spring adjustable. When the load of the moving guide seat 15 acting on the spring increases, the air pressure increases, and the stiffness of the spring increases. Conversely, when the load of the moving guide seat 15 decreases, the air pressure in the spring decreases and the stiffness decreases, thereby achieving a shock absorbing effect. The aluminum alloy track system of the crane absorbs the vibration force generated during the movement of the crane along the track system through air pressure resistance, thereby improving the movement stability of the crane.

[0022] The working principle of the aluminum alloy rail system of a crane provided by the utility model is as follows: when assembling and erecting the aluminum alloy rail system of the crane, firstly, the guide slot 12 and the synchronization slot 18 of the front end of the initial aluminum alloy guide rail 1 are respectively inserted into the corresponding guide socket 13 and the synchronization socket 19, and then the rear end of another aluminum alloy guide rail 1 is assembled and connected with the initial aluminum alloy guide rail 1 through the corresponding guide socket 13 and the synchronization socket 19, so as to limit the vertical plane movement between the two aluminum alloy guide rails 1, and then the H-shaped card block 9 is inserted into the adjacent T-shaped card slot 3 between the two aluminum alloy guide rails 1, so as to limit the vertical plane movement between the two aluminum alloy guide rails 1. The longitudinal movement limit is performed between the two aluminum alloy guide rails 1, and then the dial button 8 is pulled to drive the rectangular card block 7 to move along the corresponding avoidance groove 11 to the outside of the H-shaped card block 9, the spring 6 is elastically stretched, and then the dial button 8 is turned to drive the rectangular card block 7 to rotate until it is vertically aligned with the adjacent card slot 10, and then the card is sent to apply a force to the dial button 8, and the rectangular card block 7 is engaged with the adjacent card slot 10 through the stretching elastic force of the spring 6, so that the H-shaped card block 9 is vertically limited, thereby realizing the rapid assembly between the two aluminum alloy guide rails 1. The connection operation is convenient during the erection of the aluminum alloy track system, and then the remaining aluminum alloy guide rails 1 are sequentially assembled according to the same principle. The aluminum alloy track system can be disassembled and reused later, and then the device is fixed to the specified position with bolts through the mounting seat 2, and then the moving wheels of the crane are respectively inserted between two vertically adjacent moving guide seats 15, and the contact friction between the moving wheels and the moving guide seats 15 enables the crane to move along the aluminum alloy track system. In this process, the airbag shock absorber 14 uses air pressure resistance to absorb the vibration force generated by the moving wheels during the operation of the crane, thereby improving the operation stability of the crane. The airbag shock absorber 14 is a sealed air spring filled with compressed gas, and the compressibility of the gas is used to achieve its The airbag uses a height-adjusting valve to control the air pressure in the bag so that the stiffness of the air spring is adjustable. When the load on the moving guide seat 15 acting on the spring increases, the air pressure rises, and the stiffness of the spring increases. Conversely, when the load on the moving guide seat 15 decreases, the air pressure in the spring decreases and the stiffness decreases, thereby achieving a shock-absorbing effect. Through the plug-in relationship between the synchronous socket 19 and the synchronous slot 18, the moving guide seat 15 is subjected to force synchronously to avoid height differences between the moving guide seats 15 due to different pressure-absorbing and shock-absorbing contractions of the airbag shock absorber 14. The moving wheel of the crane is laterally offset and limited by the offset baffle 16.
