Their two main beams are connected by end beams to form a bridge structure, running longitudinally along tracks laid on elevated structures on both sides. Their main function is to vertically lift and horizontally transport heavy objects such as large workpieces and batches of goods through the lateral movement of the trolley and the lifting motion of the hook. They are widely used in industries such as machinery manufacturing, metallurgy, steel, and warehousing and logistics, efficiently completing tasks such as equipment installation and commissioning in workshops, loading and unloading of parts, and stacking and unstacking of goods in warehouses. This significantly improves the efficiency and safety of heavy object handling, reduces manual labor intensity, and makes them an indispensable key lifting equipment in industrial production processes.

[0003] The anti-collision guardrail structure of electric double girder bridge crane refers to the safety protection device installed at both ends of the crane bridge or the end of the running track to prevent equipment damage and personnel injury caused by operational errors, control system failures or accidental collisions during crane operation. Its core function is to reduce the risk of collision through physical blocking, buffering and energy absorption or signal warning.

[0025] In practical use, bolts 5 are threaded through the top of the fixing block 3 and through the insert block 4 to the inner wall of the fixing block 3, thereby fixing the connection between the first guardrail 2 and the second guardrail 6.

[0026] Preferably, the first guardrail 2, the second guardrail 6, the plug rod 7 and the slot 8 form a plug-in connection structure.

[0027] In practical use, the insert rod 7 connected to one side of the second guardrail 6 is inserted into the slot 8 opened on one side of the first guardrail 2, and at the same time, the insert block 4 at the top of the second guardrail 6 is inserted into the fixing block 3, thereby connecting the positions of the first guardrail 2 and the second guardrail 6 on the surface of the crane bridge 1.

[0028] Preferably, a rectangular through groove is formed longitudinally on the surface of the limiting frame 9, and the shape and size of the through groove are adapted to the lower vertical bar of the protective fence 10.

[0029] In practical use, the rectangular through groove on the surface of the limiting frame 9 can be used to easily fit onto the vertical bar at the bottom of the protective fence 10, thereby fixing the protective fence 10 at the top of the crane bridge 1.

[0030] Preferably, the limiting frame 9, the protective fence 10, the adjusting groove 11 and the connecting frame 12 form a plug-in connection structure.

[0031] In practical use, after the vertical bar at the bottom of the protective fence 10 is slidably adjusted to the appropriate position within the sleeved limiting frame 9, the horizontal bar on one side of the connecting frame 12 passes through the limiting frame 9 and is inserted into the corresponding adjustment groove 11 on the surface of the bottom vertical bar of the protective fence 10. At the same time, the through groove on the surface of the connecting frame 12 is sleeved on the screw 14, and the nut assembly 13 is threadedly connected to the screw 14 and tightened to abut against the surface of the connecting frame 12, thereby fixing the position of the connecting frame 12.

[0033] In practical use, three sets of adjustment slots 11 are equally spaced on the protective fence 10, which facilitates the adjustment of the position of the protective fence 10 according to the height of maintenance personnel or supporting facilities, thereby meeting the needs of most existing equipment and crane bridge 1.

[0034] Preferably, a circular through groove is formed on the surface of the connecting bracket 12, and the shape and size of the through groove are adapted to the screw 14.

[0035] In practical use, the crossbar on one side of the connecting frame 12 passes through the limiting frame 9 and is inserted into the corresponding adjustment groove 11 on the surface of the bottom vertical bar of the protective fence 10. At the same time, the through groove on the surface of the connecting frame 12 is sleeved on the screw 14, thereby facilitating the connection of the protective fence 10 on the limiting frame 9.

[0036] Working principle: When using the crane bridge 1, the first guardrail 2 is fitted onto the surface of the crane bridge 1, and the insert 7 connected to one side of the second guardrail 6 is inserted into the slot 8 opened on one side of the first guardrail 2. At the same time, the insert 4 at the top of the second guardrail 6 is inserted into the fixing block 3, thereby connecting the positions of the first guardrail 2 and the second guardrail 6 on the surface of the crane bridge 1. The rubber first guardrail 2 and the second guardrail 6 protect the surface of the crane bridge 1 from impacts during operation. Simultaneously, bolts 5 pass through the top of the fixing block 3 and through the insert 4, threadedly connecting to the inner wall of the fixing block 3, thus securing the connection between the first guardrail 2 and the second guardrail 6. Furthermore, during use, peripheral equipment of different heights can be fitted to the crane bridge 1. (Such as loading and unloading platforms, shelves) In conjunction with the vertical bar at the bottom of the protective fence 10, after sliding and adjusting it to the appropriate position within the sleeved limit frame 9, the horizontal bar on one side of the connecting frame 12 passes through the limit frame 9 and is inserted into the corresponding adjustment groove 11 on the surface of the bottom vertical bar of the protective fence 10. At the same time, the through groove on the surface of the connecting frame 12 is sleeved on the screw 14, and the nut assembly 13 is threadedly connected to the screw 14 and tightened to abut against the surface of the connecting frame 12, thereby fixing the position of the connecting frame 12, and thus fixing the position of the protective fence 10 on the surface of the limit frame 9. At this time, the height of the protective fence 10 can adapt to the safety protection needs of different environments, avoiding insufficient protection due to fixed height, which would affect the safety of operators in maintaining the rails, electrical equipment, lubrication components, etc. on the top of the crane bridge 1.

[0037] When long-term use causes the first guardrail 2 and the second guardrail 6 to age, repeat the above operation. First, loosen the nut assembly 13 threaded to the screw 14, then push the protective fence 10 sleeved in the limit frame 9 upward to disassemble it. Then, unscrew the bolt 5 threaded between the fixing block 3 and the insert block 4, and pull the first guardrail 2 and the second guardrail 6 inserted together to both sides to replace them.
