Description

Technical Field

[0001] The utility model relates to the technical field of crane components, in particular to a single girder for crossing tracks. Background Technique

[0002] A single girder crane usually refers to a single girder bridge crane, with the English name Single-beam Crane. The main girder of the single girder crane bridge is mostly made of I-shaped steel or a combined section of steel and steel plates. The hoisting trolley is often a chain block, an electric hoist or assembled with a hoist as a hoisting mechanism component.

[0003] The single girder structure of the single girder crane is simple and has no additional objects. Generally, it is at a very high position. When repairing the equipment at the single girder of the crane, the protection is relatively low, reducing the safety factor of the repairman. At the same time, most of the existing single girders are fixed in position by bolts, and corresponding external tools are required for disassembly and installation, which is rather troublesome.

[0028] In order to enable the over-track single beam to have the effects of improving the protection performance of the single beam and increasing the safety factor of maintenance workers, and to enable the over-track single beam to have the effect of facilitating the quick installation and disassembly of the single beam, as shown in the attached Figures 1-6As shown, the present application adopts the following structure, through the support plate 2, the connecting rod 4, the supporting cross bar 6, the connecting slider 8, the first spring 9, the limiting card plate 10 and the positioning ring 11, the connecting plate 14, the limiting card block 15, the second spring 16, the guide roller 17, the traction rope 18, the control handle 19 and the mounting seat 21. During use, when it is necessary to go up to the top of the single beam body 1 to repair the equipment, press the control plate 12 to make the connecting slider 8 and the limiting card plate 10 slide up along the supporting slide bar 7, squeezing the first spring 9. At the same time, lift the supporting cross bar 6 to make the connecting rod 4 in a vertical state. Then, release the control plate 12. Under the elastic force of the first spring 9, the limiting card plate 10 is inserted into the positioning ring 11, thereby limiting the position of the supporting cross bar 6 and the connecting rod 4, so that a guardrail is formed between the supporting cross bar 6, the connecting rod 4 and the support plate 2 to protect the safety of the maintenance personnel. After the maintenance is completed, press the control plate 12 again to make the connecting slider 8 and the limiting card plate 10 slide up along the supporting slide bar 7, squeezing the first spring 9 to disengage the limiting card plate 10. The positioning ring 11 is then used to rotate the connecting rod 4 to lower the supporting cross bar to reduce the space occupied by the supporting cross bar 6. When inserting the single beam, the corresponding lifting equipment is used to lift the control handle 19. Under the action of the traction rope 18, the connecting plate 14 is pulled to slide along the limiting slide bar 13, squeezing the second spring 16 to quickly disengage the limiting block 15 from the mounting seat 21, and the single beam is quickly disassembled. When installing, the corresponding lifting equipment is also used to lift the control handle 19. Under the action of the traction rope 18, the connecting plate 14 is pulled. The connecting plate 14 slides along the limiting slide bar 13 and the second spring 16 is squeezed to quickly disengage the limiting block 15 from the mounting seat 21. The connecting plate 14 is made to slide along the limiting slide bar 13, squeezing the second spring 16 so that the limiting block 15 is accommodated in the installation groove, and the single beam is lowered to the corresponding installation seat 21. When the lifting equipment is separated from the control handle 19, the limiting block 15 is ejected under the elastic force of the second spring 16 and is stuck in the installation seat 21, completing the rapid installation of the single beam, thereby enabling the over-track single beam to improve the protection of the single beam, increase the safety factor of the maintenance personnel, and facilitate the rapid installation and disassembly of the single beam.
