Description
Technical Field
[0001] The utility model is applicable to the technical field of gantry cranes, and particularly relates to a temporary rigid fixing device for outriggers used for disassembling gantry cranes. Background Art
[0002] At present, gantry crane is a deformation of bridge crane. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam. It can walk directly on the track on the ground. Both ends of the main beam can have outward cantilever beams, which need to be removed after the construction is completed. During the dismantling process of the gantry crane, in order to ensure safety, it is often necessary to temporarily fix the legs of the gantry crane to ensure that the legs are always in a vertical state when the crossbeam is removed to prevent accidents caused by the tilt of the legs.
[0003] However, nowadays, when temporarily reinforcing the legs of gantry cranes, the support frame with a simple structure cannot be adjusted for applicability, which results in different leg heights and different center of gravity heights for cranes of different specifications when supporting and fixing them, which makes it impossible for the fixing device to adjust the support center of gravity position, which easily affects the fixing stability of the legs. Therefore, we propose a temporary rigid fixing device for the legs of gantry cranes for disassembly. Utility Model Content
[0004] The main purpose of the utility model is to provide a temporary rigid fixing device for the legs of a gantry crane for disassembly, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A temporary rigid fixing device for outriggers for disassembly of a gantry crane comprises a mounting base and a mounting plate, wherein sliding plates are slidably mounted on both sides of the top of the mounting base, and fixing plates are fixedly mounted on both ends of the outer side of each sliding plate, and the bottom surface of the fixing plate is slidably fitted to the top surface of the mounting base;
[0007] Each of the sliding plates and the mounting plate is fixedly mounted on both ends of the outer side, a rotating rod is rotatably mounted between the sides of each two groups of mounting plates, a hollow tube is fixedly sleeved on the middle end surface of the rotating rod, and the inside of each hollow tube away from the sliding plate is slidably mounted on a movable rod, and the top of the movable rod is fixedly sleeved on the outer side of the rotating rod;
[0008] A clamping frame is fixedly mounted on the side surface of each mounting plate, and adjusting bolts are screwed inside the two ends of the side of each clamping frame through threads, and a fitting plate is rotatably mounted on the side of each adjusting bolt through a bearing.
[0009] By adopting the above technical solution, the hollow tube and the movable rod are rotated and installed on the mounting base and the outside of the clamping frame by rotating the rod, and the position of the bonding plate is adjusted by adjusting the adjusting bolts, so that the clamping frame can adjust the applicability of the supporting position according to the center of gravity position of the leg rod, thereby improving the applicability of the entire supporting and fixing mechanism while ensuring that it can provide sufficient supporting and fixing force for the disassembly and separation of leg rods of different specifications.
[0010] As an optional solution of the technical solution of the present application, a plug-in slot is opened inside the middle end of the mounting base, a leg rod is movably plugged into the plug-in slot, and a clamping frame is located at both ends of the outer side of the leg rod.
[0011] By adopting the above technical solution, the insertion and reception processing of the leg rod is realized through the structural effect of the plug-in groove.
[0012] As an optional solution to the technical solution of the present application, a limiting bolt is screwed through the middle end of each fixed plate via a thread, limiting screw holes are provided on both sides of the top of the mounting base, and the number of limiting screw holes is several groups, and the outer end surfaces of each rotating rod are screwed with limiting nuts via a thread, and the limiting nuts are located on the outside of the support plate.
[0013] By adopting the above technical solution, the mobility of the sliding plate and the rotating rod can be limited by tightening the limit nut and the limit bolt.
[0014] As an optional solution of the technical solution of the present application, a protective soft pad is fixedly bonded to the outer surface of each of the laminated panels.
[0015] By adopting the above technical solution, the structural function of the protective cushion can prevent the laminating plate from laminating the leg rod and causing wear.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. The technical solution of the present application is a temporary rigid fixing device for the outriggers of a gantry crane for disassembly, wherein the hollow tube and the movable rod are respectively rotated and arranged on the outside of the sliding plate and the mounting plate by a rotating rod, so that after the sliding plate is pushed horizontally to move horizontally on the surface of the mounting base, the hollow tube and the movable rod can rotate relative to each other at the connection between the mounting base and the outside of the outrigger rod, and the supporting angles of the hollow tube and the movable rod can be adjusted. After the clamping frame and the movable rod are pulled outward, the vertical position of the clamping frame can be adjusted, so that the clamping frame can adjust the applicability of the supporting position according to the center of gravity position of the outrigger rod, thereby improving the applicability of the entire supporting and fixing mechanism while ensuring that it can provide sufficient supporting and fixing force for the disassembly and separation of outrigger rods of different specifications.
