Technical Field
[0001] This utility model relates to the field of bridge crane technology, and in particular to a modular and detachable bridge crane end beam connection structure. Background Technology
[0002] A bridge crane is a lifting device that spans across workshops, warehouses, and material yards to lift and transport materials. Its two ends rest on tall concrete pillars or metal supports, resembling a bridge. The end beams are an important component of the bridge crane, used to support the main beams and enable the crane to run on the rails.
[0003] In the production, transportation, and installation of bridge cranes, the end beam connection structure plays a crucial role. Traditional bridge crane end beam connection structures are mostly integral or fixed using complex welding methods. During transportation, the large overall volume of the end beam makes it inconvenient to handle and transport, increasing transportation costs and difficulties. During installation and maintenance, if damage occurs, the entire end beam often needs to be replaced, which is not only costly but also inefficient. Therefore, we propose a modular and detachable bridge crane end beam connection structure to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular, detachable bridge crane end beam connection structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A modular, detachable bridge crane end beam connection structure includes an end beam body, which comprises a beam frame one and a beam frame two. A connecting seat one is fixedly installed on the front and rear inner walls of beam frame one, and a connecting seat two is fixedly installed on the front and rear sides of beam frame two. The top of connecting seat one has a T-shaped mounting groove with one side open. A T-shaped mounting seat adapted to the T-shaped mounting groove is fixedly installed on one side of connecting seat two. A fixing groove is opened on one side of the T-shaped mounting seat, and a screw hole is opened on the inner wall of one side of the T-shaped mounting groove. A fixing screw adapted to the fixing groove is threaded into the screw hole.
[0007] Preferably, a connecting plate 1 is fixedly installed on both the front and rear sides of beam frame 1, and a connecting plate 2 is fixedly installed on both the front and rear sides of beam frame 2, with a fixing mechanism provided between connecting plate 1 and connecting plate 2.
[0008] Preferably, the fixing mechanism includes mounting holes, fixing bolts, and fixing nuts. Both connecting plate one and connecting plate two have multiple mounting holes. The fixing bolts are installed in two corresponding mounting holes, and the fixing nuts are threaded onto the fixing bolts. An anti-loosening mechanism is provided between the fixing bolts and the fixing nuts.
[0009] Preferably, the anti-loosening mechanism includes a movable groove, a trapezoidal anti-loosening seat, and a fixing spring. The top of the fixing bolt is provided with a movable groove, and a trapezoidal anti-loosening seat for fixing the nut to prevent loosening is slidably installed in the movable groove. A fixing spring is fixedly installed at the bottom of the trapezoidal anti-loosening seat, and the bottom end of the fixing spring is fixedly installed on the bottom inner wall of the movable groove.
[0010] Preferably, the top of beam frame one and beam frame two are equipped with the same reinforcing plate, and a locking mechanism is provided between the reinforcing plate and beam frame one and beam frame two.
[0011] Preferably, the locking mechanism includes a socket, a fixing screw, and a fixing nut. The reinforcing plate has a socket, and the top of beam frame one and beam frame two are equipped with fixing screws. The fixing screws pass through the corresponding sockets and are threaded with fixing nuts.
[0012] Preferably, multiple reinforcing ribs are installed on the inner walls of beam frame one and beam frame two, and the multiple reinforcing ribs are arranged at equal intervals.
[0013] The beneficial effects of this utility model are:
[0014] 1. By setting up T-shaped mounting slots and T-shaped mounting seats, the beam frame one and beam frame two can be quickly positioned and initially connected. Then, the T-shaped mounting seats are fixed in the T-shaped mounting slots with fixing screws, which further enhances the stability of the connection. This structural design makes the installation and disassembly of the end beams more convenient and facilitates modular production and transportation.
[0015] 2. The fixing mechanism between connecting plate one and connecting plate two, through the cooperation of multiple fixing bolts and fixing nut two, further improves the firmness of the connection between beam frame one and beam frame two. At the same time, the trapezoidal anti-loosening seat in the anti-loosening mechanism is in close contact with fixing nut two under the action of the fixing spring, which can effectively prevent fixing nut two from loosening and ensure the reliability of the connection.
[0016] 3. The reinforcing plates at the top of beam frame one and beam frame two are fixed by a locking mechanism, which can reinforce the connection between beam frame one and beam frame two, and improve the overall load-bearing capacity and stability of the end beam. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses a modular, detachable bridge crane end beam connection structure.
[0025] Reference Figure 1-5 A modular, detachable bridge crane end beam connection structure includes an end beam body 1, which includes a beam frame 101 and a beam frame 102. A connecting seat 201 is fixedly installed on the front and rear inner walls of the beam frame 101, and a connecting seat 202 is fixedly installed on the front and rear sides of the beam frame 102. The top of the connecting seat 101 has a T-shaped mounting groove 203 with one side open. A T-shaped mounting seat 204, adapted to the T-shaped mounting groove 203, is fixedly installed on one side of the connecting seat 202. A fixing groove 301 is opened on one side of the T-shaped mounting seat 204, and a screw hole 302 is opened on the inner wall of one side of the T-shaped mounting groove 203. A fixing screw 303, adapted to the fixing groove 301, is threaded into the screw hole 302.
[0026] In this embodiment, connecting plates 501 are fixedly installed on both the front and rear sides of beam frame 101, and connecting plates 502 are fixedly installed on both the front and rear sides of beam frame 102. A fixing mechanism is provided between connecting plates 501 and 502. This arrangement, by increasing the connection contact area, further improves the stability and load-bearing capacity of the connection between beam frame 101 and beam frame 102.
[0027] In this embodiment, the fixing mechanism includes mounting holes 503, fixing bolts 504, and fixing nuts 505. Both connecting plate 501 and connecting plate 502 have multiple mounting holes 503. Fixing bolts 504 are installed in two corresponding mounting holes 503, and fixing nuts 505 are threaded onto the fixing bolts 504. An anti-loosening mechanism is provided between the fixing bolts 504 and the fixing nuts 505. The cooperation of multiple sets of mounting holes 503 with the fixing bolts 504 and fixing nuts 505 can distribute the stress on the connection points, preventing excessive local stress from causing structural damage.
[0028] In this embodiment, the anti-loosening mechanism includes a movable groove 601, a trapezoidal anti-loosening seat, and a fixing spring 603. The top of the fixing bolt 504 has a movable groove 601. A trapezoidal anti-loosening seat 602 for preventing the fixing nut 505 from loosening is slidably installed within the movable groove 601. A fixing spring 603 is fixedly installed at the bottom of the trapezoidal anti-loosening seat, and the bottom end of the fixing spring 603 is fixedly installed on the bottom inner wall of the movable groove 601. The spring force drives the trapezoidal anti-loosening seat to fit tightly against the fixing nut 505, effectively resisting external forces such as vibration and preventing the fixing nut 505 from accidentally loosening.
[0029] In this embodiment, the top of beam frame 101 and beam frame 2 102 are equipped with the same reinforcing plate 402. A locking mechanism is provided between the reinforcing plate 402 and beam frame 101 and beam frame 2 102. The locking mechanism includes a socket 403, a fixing screw 401, and a fixing nut 404. The reinforcing plate 402 has a socket 403. The fixing screw 401 is installed on the top of beam frame 101 and beam frame 2 102. The fixing screw 401 passes through the corresponding socket 403 and is threaded with the fixing nut 404. The cooperation between the reinforcing plate 402 and the locking mechanism can constrain the connection part of beam frame 101 and beam frame 2 102 from the top, reduce the connection gap, and improve the rigidity of the overall structure.
[0030] In this embodiment, multiple reinforcing ribs 103 are installed on the inner walls of beam frame one 101 and beam frame two 102, and the multiple reinforcing ribs 103 are arranged at equal intervals. The equally spaced reinforcing ribs 103 can uniformly enhance the deformation resistance of the beam frame, so that the beam frame can still maintain structural stability when bearing heavy loads.
[0031] The working principle of this utility model is as follows: When installing the modular and detachable bridge crane end beam connection structure, firstly, align the T-shaped mounting seat 204 on the second beam 102 with the T-shaped mounting groove 203 on the first beam 101 connecting seat 201, and insert it from top to bottom to achieve the initial positioning of the first beam 101 and the second beam 102. Then, screw the fixing screw 303 into the threaded hole so that its end is inserted into the fixing groove 301 of the T-shaped mounting seat 204 to complete the initial fixing of the two.
[0032] Next, align the connecting plate 501 on beam frame 101 with the connecting plate 502 on beam frame 202, pass the fixing bolt 504 through the corresponding mounting hole 503, screw on the fixing nut 505 and tighten it. During the tightening process, the fixing nut 505 will squeeze the trapezoidal anti-loosening seat, causing it to compress the fixing spring 603 and sink into the moving groove 601. After the fixing nut 505 is tightened, the trapezoidal anti-loosening seat will pop out under the elastic force of the fixing spring 603 and fit tightly against the side of the fixing nut 505 to prevent it from loosening, further strengthening the connection between beam frame 101 and beam frame 202.
[0033] Next, the reinforcing plate 402 is placed on top of beam frame 101 and beam frame 2 102, and the fixing screw 401 is passed through the insertion hole 403 on the reinforcing plate 402. The fixing nut 404 is screwed on and tightened. The connection part is reinforced by the reinforcing plate 402, thereby improving the stability of the overall structure.
[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
