Technical Field
[0001] This utility model relates to the field of road and bridge construction technology, specifically to a lifting device for road and bridge construction. Background Technology
[0002] Road and bridge construction aims to improve people's travel convenience. During the construction process, it is necessary to transport the bridge support components from the bottom of the road and bridge to the top of the road and bridge for the bridge to be constructed. Lifting equipment is required when transporting these bridge support components to the top of the road and bridge.
[0003] For example, application number CN202323290402.3 relates to a lifting device for road and bridge construction, including a base plate.

A baffle is provided on the left side of the fixed frame, sliding components are provided at the bottom of both sides of the fixed frame, and positioning mechanisms are provided on the left side of both sides of the fixed frame.
[0007] In a preferred embodiment of this utility model, the sliding assembly includes a connecting plate, a rotating shaft, and a sliding groove. The sliding grooves are all located on the left side of the bottom of both sides of the fixed frame. The connecting plates are all fixedly connected to the bottom of both sides of the baffle. The rotating shaft is fixedly connected to the right side of the inner side of the connecting plate, and the rotating shaft is slidably connected to the sliding groove.
[0008] In a preferred embodiment of this utility model, the positioning mechanism includes a mounting box, a groove, a positioning element, a positioning slot, a fixing plate, a first spring, and a fixing element. The mounting box is fixedly connected to both sides of the baffle. The groove is located on the right side of the mounting box.

[0013] As a preferred embodiment of this utility model, a pull rod is fixedly connected to the top of the positioning member, and the top end of the pull rod extends through to the top of the mounting box.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, by setting a baffle, when the clamping plate inside the fixed frame clamps the material, moves the baffle to block the left side of the fixed frame, preventing the material from falling during lifting and lowering. This solves the problem that, due to the open design on the left side of the fixed frame, if an accidental slip occurs during the process of the clamping plate lifting the material, the material may fall out from the left side of the fixed frame, potentially causing injury to the operator and increasing safety risks. It has the advantage of blocking the material inside the fixed frame to prevent the material from falling.
[0016] 2. This utility model uses a sliding component to move the baffle and connecting plate, which in turn moves the connecting plate and rotating shaft within the slide groove. The rotating shaft then moves to the leftmost position within the slide groove, and finally, the baffle and connecting plate rotate around the rotating shaft, causing the right side of the baffle to align with the left side of the fixed frame. This allows the rotating shaft to move within the slide groove, effectively driving the baffle's movement. Furthermore, a positioning mechanism is used. When the right side of the baffle aligns with the left side of the fixed frame, the fixing component inside the fixed plate moves and inserts into a groove in the mounting box. Simultaneously, a positioning component contacts the fixing component, causing the positioning component to compress and contract the first spring, aligning the positioning component with the positioning groove. The first spring then releases pressure, causing the positioning component to move and insert into the corresponding positioning groove. Thus, the positioning component and the fixing component work together to position the baffle after rotation.
[0017] 3. This utility model, by setting a U-shaped frame and a second spring, prevents the fixing component from falling into the fixing plate when not in use. The right end of the fixing component is fixed inside the U-shaped frame by the second spring. When positioning is required before the baffle rotates, the fixing component is moved, causing the positioning component to drive the second spring to compress and contract. Then, when the baffle rotates and fits against the left side of the fixing frame, the pressure is released by the second spring, causing the fixing component to move and insert into the groove of the mounting box for positioning. Furthermore, by setting a fixing rod and a handle, when the fixing component moves, the handle is gripped, causing the handle to drive the fixing component to move, and then the fixing component drives the second spring to compress and contract. Thus, the handle and the fixing component work together to facilitate the operator's stable grip when moving the fixing component, while reducing the difficulty and labor intensity of moving the fixing component.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 3 As shown, the present invention provides a lifting device for road and bridge construction, including a base plate 1, a buffer plate 2, a lifting box 3, a fixed frame 4, a clamping box 5, a clamping plate 6, and supporting legs 7. The lifting box 3 is fixedly connected to the top of the base plate 1, the buffer plate 2 is sleeved on the bottom of the surface of the lifting box 3, the fixed frame 4 is movably connected to the left side of the lifting box 3, the clamping box 5 is connected to the right side inside the fixed frame 4, the clamping plate 6 is movably connected to the left side of the clamping box 5, and the supporting legs 7 are all fixedly connected to the four corners of the bottom of the base plate 1. A baffle 8 is provided on the left side of the fixed frame 4, sliding components 9 are provided on the bottom of both sides of the fixed frame 4, and positioning mechanisms 10 are provided on the left side of both sides of the fixed frame 4.
[0024] refer to Figure 2 The sliding component 9 includes a connecting plate 91, a rotating shaft 92, and a sliding groove 93. The sliding groove 93 is opened on the left side of the bottom of both sides of the fixed frame 4. The connecting plate 91 is fixedly connected to the bottom of both sides of the baffle 8. The rotating shaft 92 is fixedly connected to the right side of the inner side of the connecting plate 91. The rotating shaft 92 is slidably connected to the sliding groove 93.
[0025] As a technical optimization of this utility model, by setting a sliding component 9, the baffle 8 drives the connecting plate 91 to move, and then the connecting plate 91 drives the rotating shaft 92 to move inside the slide groove 93. After that, the rotating shaft 92 moves to the leftmost side inside the slide groove 93. Finally, the baffle 8 drives the connecting plate 91 to rotate around the rotating shaft 92 as the center, and then the right side of the baffle 8 fits with the left side of the fixed frame 4, so that the rotating shaft 92 can effectively drive the baffle 8 to move by moving inside the slide groove 93.
[0026] refer to Figure 3 The positioning mechanism 10 includes a mounting box 101, a groove 102, a positioning element 103, a positioning slot 104, a fixing plate 105, a first spring 106, and a fixing element 107. The mounting box 101 is fixedly connected to both sides of the baffle 8. The groove 102 is opened on the right side of the mounting box 101. The fixing plates 105 are fixedly connected to the left sides of both sides of the fixing frame 4. The fixing element 107 is movably connected inside the groove 102. The first spring 106 is fixedly connected to the top inside the groove 102. The positioning element 103 is fixedly connected to the other end of the first spring 106. The positioning slot 104 is opened on the top of the fixing element 107. The positioning element 103 is movably connected to the positioning slot 104. The right side of the fixing element 107 extends through to the right side of the fixing plate 105.
[0027] As a technical optimization of this utility model, by setting a positioning mechanism 10, when the right side of the baffle 8 is attached to the left side of the fixed frame 4, the fixing member 107 inside the fixed plate 105 moves, and then the fixing member 107 is inserted into the groove 102 opened in the mounting box 101. At the same time, the positioning member 103 contacts the fixing member 107, so that the positioning member 103 drives the first spring 106 to compress and shrink, and then the positioning member 103 corresponds to the positioning groove 104. After that, the first spring 106 releases pressure and drives the positioning member 103 to move and insert into the corresponding positioning groove 104, so that the positioning member 103 and the fixing member 107 work together to complete the positioning of the baffle 8 after rotation.
[0028] refer to Figure 3 A U-shaped frame 11 is fixedly connected to the right side of the fixing plate 105, and a second spring 12 is fixedly connected to the right side of the fixing member 107. The other end of the second spring 12 is fixedly connected to the right side of the inner wall of the U-shaped frame 11.
[0029] As a technical optimization of this utility model, by setting a U-shaped frame 11 and a second spring 12, in order to prevent the fixing member 107 from falling into the fixing plate 105 when not in use, the right end of the fixing member 107 is fixed inside the U-shaped frame 11 by the second spring 12. When positioning is required before the baffle 8 rotates, the fixing member 107 is moved, so that the positioning member 103 drives the second spring 12 to compress and shrink. Then, when the baffle 8 rotates and fits against the left side of the fixing frame 4, the pressure is released by the second spring 12, which drives the fixing member 107 to move and insert into the groove 102 of the mounting box 101 for positioning.
[0030] refer to Figure 3 A fixing rod 13 is fixedly connected to the right side of the fixing member 107. The right end of the fixing rod 13 extends through to the right side of the U-shaped frame 11, and the other end of the fixing rod 13 is fixedly connected to a handle 14.
[0031] As a technical optimization of this utility model, by setting a fixed rod 13 and a handle 14, when the fixed part 107 moves, the handle 14 is gripped, causing the handle 14 to drive the fixed part 107 to move. Then, the fixed part 107 drives the second spring 12 to compress and contract, so that the handle 14 and the fixed part 107 can be used together to facilitate the operator to hold the fixed part 107 firmly when moving it, while reducing the difficulty and labor intensity of moving the fixed part 107.
[0032] refer to Figure 1 An L-shaped plate 15 is fixedly connected to the left side of the bottom of the fixed frame 4, and the L-shaped plate 15 is movably connected to the baffle 8.
[0033] As a technical optimization of this utility model, by setting an L-shaped plate 15, when the baffle 8 needs to be stored, the baffle 8 drives the connecting plate 91 to rotate on the left side inside the slide groove 93 with the rotating shaft 92 as the center. Then, the rotating shaft 92 moves from the left side to the right side inside the slide groove 93, while the L-shaped plate 15 at the bottom of the fixed frame 4 stably stores the baffle 8 and provides reliable support for it, ensuring stability and safety during operation.
[0034] refer to Figure 2 A handle 16 is fixedly connected to the top left side of the baffle 8, and the surface of the handle 16 is provided with anti-slip texture 17.
[0035] As a technical optimization of this utility model, by setting a handle 16 and anti-slip texture 17, when the baffle 8 moves and rotates, the baffle 8 is moved by gripping the handle 16 on the left side of the baffle 8. At the same time, when gripping the handle 16, it comes into contact with the anti-slip texture 17, increasing the friction generated during contact and preventing the baffle 8 from slipping out of the hand. This makes the handle 16 a reliable gripping point for the operator, thereby ensuring the safety and convenience of operating the baffle 8.
[0036] refer to Figure 3 A pull rod 18 is fixedly connected to the top of the positioning component 103, and the top end of the pull rod 18 extends through to the top of the mounting box 101.
[0037] As a technical optimization of this utility model, by setting a pull rod 18, when it is necessary to cancel the positioning of the baffle 7, the pull rod 18 is moved, causing the positioning member 103 to move. At the same time, the positioning member 103 causes the first spring 106 to compress and contract, thereby causing the fixing member 107 to be pulled out from the groove 02 to complete the cancellation of the positioning of the baffle 7.
[0038] The working principle and usage process of this utility model are as follows: During use, gripping the handle 16 moves the baffle 8, causing the baffle 8 to move the connecting plate 91. Then, the connecting plate 91 moves the rotating shaft 92 within the slide groove 93. Next, the rotating shaft 92 moves to the leftmost position within the slide groove 93. Finally, the baffle 8 rotates the connecting plate 91 around the rotating shaft 92, causing the right side of the baffle 8 to align with the left side of the fixed frame 4. Simultaneously, gripping the handle 14 moves the fixing member 107, causing the fixing member 107 to compress and contract the second spring 12. When the baffle 8 aligns with the fixed frame 4, the second... Spring 12 releases pressure, causing the fixing member 107 to move and insert into the groove 102 of the mounting box 101. At the same time, the positioning member 103 contacts the fixing member 107, causing the positioning member 103 to drive the first spring 106 to compress and contract, so that the positioning member 103 corresponds to the positioning groove 104. Then, the first spring 106 releases pressure, causing the positioning member 103 to move and insert into the corresponding positioning groove 104. Thus, the positioning member 103 and the fixing member 107 work together to position the baffle 8 after it rotates, preventing the material from falling when it is raised or lowered. This has the advantage of blocking the material inside the fixed frame 4 and preventing the material from falling.
[0039] In summary, this lifting equipment for bridge and road construction, by setting up a baffle 8, can prevent the material from falling off the left side of the fixed frame 4 when the clamping plate 6 inside the fixed frame 4 clamps the material. This solves the problem that, due to the open design on the left side of the fixed frame, if an accidental slip occurs during the process of the clamping plate lifting the material, the material may fall out from the left side of the fixed frame, potentially causing injury to the operator and increasing safety risks. The equipment effectively prevents the material inside the fixed frame from falling off.
