Technical Field

[0001] The present application relates to the technical field of bridge erection machines, and in particular to a bridge erection machine support leg. Background Art

[0002] A bridge erection machine is a device that places prefabricated beams on prefabricated bridge piers. A bridge erection machine belongs to the category of cranes, and its main function is to lift beams, transport them to the location, and then put them down. A bridge erection machine is very different from a general crane. It requires harsh conditions and has the ability to travel on the beams, or longitudinal movement.

[0003] A bridge erection machine outrigger structure mentioned in an existing Chinese public patent (authorization announcement number: CN220013380U) includes a crossbeam, and the crossbeam, telescopic sleeve lifting jack, telescopic sleeve rod, operating platform, jacking cylinder, and cantilever beam constitute the front outrigger of the bridge erection machine. Two groups of telescopic sleeve lifting jacks are installed at the bottom of the crossbeam, a telescopic sleeve rod is movably installed below the crossbeam, an operating platform is movably installed inside the telescopic sleeve rod, a jacking cylinder is arranged at the bottom of the telescopic sleeve rod, a cantilever beam is fixedly installed at the bottom of the telescopic sleeve rod, and a connecting hinge is movably installed at the top of the telescopic sleeve rod. By installing devices such as the crossbeam, the telescopic sleeve lifting jack, the telescopic sleeve rod, the operating platform, and the jacking cylinder, the purpose of being able to greatly extend and retract, adapt to different pier height requirements, meet the pier column hoisting requirements, be anchored on the cap, and reduce foundation treatment work is achieved.

[0004] In the above patent, by installing devices such as crossbeams, the purpose of being able to expand and contract greatly, adapting to different pier height requirements and reducing foundation treatment work is achieved. However, in daily use, when installing a bridge, it is necessary to first use outriggers to be erected on the piers to support the main beam of the bridge-building machine, and then use the main beam to transport the bridge. However, due to the large size and high center of gravity of the bridge-building machine, during the movement of the main beam, the bridge-building machine cannot be effectively supported by only simple contact between the bottom of the outriggers of the bridge-building machine and the top of the pier, and it is easy to shake and tilt, thereby causing safety hazards. For this reason, the present application provides a bridge-building machine outrigger. Utility Model Content

[0005] The purpose of the present application is to solve the problem that during the movement of the main beam, the bridge-building machine cannot be effectively and stably supported by only simple contact between the bottom of the bridge-building machine's legs and the top of the pier, and it is easy to shake and tilt, thus causing safety hazards. The present application provides a bridge-building machine leg.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A bridge-building machine support leg comprises a top plate, the top of the top plate is fixedly connected to a supporting leg, the inside of the supporting leg is fixedly connected to a fixing plate, the top of the fixing plate is symmetrically fixedly connected to two hydraulic telescopic rods, the output ends of the two hydraulic telescopic rods are both penetrated and fixedly connected to connecting rods, the bottom of the connecting rods is fixedly connected to a bottom plate, the bottom of the bottom plate is fixedly connected to a supporting block, the inside of the supporting block is symmetrically installed with auxiliary components, and the bottom of the bottom plate is symmetrically installed with supporting components.

[0008] By adopting the above technical scheme, the support legs are first moved to the top of the pier by the bridge-building machine, and then the hydraulic telescopic rod is started to drive the connecting rod to gradually descend, thereby driving the bottom plate and the support block to descend together through the connecting rod, until the bottom of the support block is completely fitted with the top of the pier, and then the operation of the hydraulic telescopic rod is stopped, and the bridge-building machine is initially supported and stabilized by the fit of the support block and the pier. When the support block and the pier are completely and stably fitted, the auxiliary components and support components inside the support block can be pulled out, and the contact surface between the support block and the pier is effectively increased through the cooperation of the auxiliary components and the support components, thereby increasing the overall stability of the support block, thereby ensuring that the support block is more stable when supporting the main beam of the bridge-building machine and reducing safety hazards.

[0009] Furthermore, the auxiliary component includes an adjustment plate symmetrically and slidably connected to the inside of the support block, the bottom of the adjustment plate is symmetrically and fixedly connected to a fixed block, both sides of the adjustment plate are fixedly connected to sliders, the bottom of the fixed block is fixedly connected to a connecting plate 1, the bottom of the fixed block is fixedly connected to a connecting plate 2, one side of the connecting plate 1 is rotatably connected to an L-shaped plate, the bottom of the L-shaped plate is fixedly connected to an auxiliary leg, and one side of the connecting plate 2 is rotatably connected to a rotating plate.

[0010] By adopting the above technical solution, the auxiliary legs that pop out on both sides can effectively increase the contact area between the support block and the bridge pier, thereby increasing the overall stability of the support block, thereby ensuring that the support block is more stable when supporting the main beam of the bridge erection machine and reducing safety hazards.

[0011] Furthermore, both sides of the support block are provided with slide grooves, the support block is symmetrically fixedly connected with stoppers, and the slider is slidably connected inside the slide grooves.

[0012] By adopting the above technical solution, the movement of the adjustment plate can be guided through the cooperation of the sliding groove and the sliding block.

[0013] Furthermore, a non-slip pad is fixedly connected to the bottom of the auxiliary leg.

[0014] By adopting the above technical solution, the friction between the auxiliary supporting leg and the bridge pier can be improved by the anti-skid pad.

[0015] Furthermore, one end of the L-shaped plate away from the auxiliary support leg passes through a guide column 1 and is rotatably connected thereto, one end of the rotatable plate passes through a guide column 2 and is rotatably connected thereto, a limiting rod is fixedly connected to the outer wall of the guide column 1, and one end of the limiting rod away from the guide column 1 is fixedly connected to the outer wall of the guide column 2.

[0016] By adopting the above technical solution, when the guide column 2 rotates, it will pull the limit rod to move. When the limit rod moves, it will drive the L-shaped plate to rotate through the guide column 1, thereby popping out the auxiliary support leg at the bottom of the L-shaped plate.

[0017] Furthermore, a rotating rod is rotatably connected to one side of the guide column 2, a connecting column 1 is fixedly connected to the rotating rod, a hinge block 1 is fixedly connected to the bottom of the adjustment plate, a connecting column 2 is rotatably connected inside the hinge block 1, a compression spring is fixedly connected to the connecting column 2, the other end of the compression spring is fixedly connected to the connecting column 1, and a limiting block is fixedly connected to the bottom of the fixed block.

[0018] By adopting the above technical solution, according to the elasticity of the compression spring, the connecting column 1 and the rotating rod are pushed to rotate on the side of the guide column 2, thereby driving the rotating plate to rotate perpendicular to the connecting plate 2.

[0019] Furthermore, the support assembly includes an articulated block 2 symmetrically fixedly connected to the bottom of the base plate, the articulated block 2 is internally rotatably connected to an auxiliary frame, one side of the auxiliary frame is symmetrically fixedly connected to an articulated block 3, one side of the support block is symmetrically fixedly connected to an articulated block 4, and the articulated block 4 is internally rotatably connected to a mortgage plate.

[0020] By adopting the above technical solution, the contact area between the support block and the bridge pier can be further increased through the stabilized auxiliary frame, thereby increasing the overall stability of the support block, thereby ensuring that the support block is more stable when supporting the main beam of the bridge erection machine and reducing safety hazards.

[0021] Furthermore, a threaded hole is formed through one end of the mortgage plate, and a bolt is threadedly connected through the inside of the hinge block three.

[0022] By adopting the above technical solution, the bolt is screwed into the hinge block three and passed through the threaded hole, so as to support and stabilize the auxiliary frame through the mortgage plate.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application is provided with an auxiliary component. When the rotating plate on one side of the second connecting plate moves to the outside of the supporting block, the elasticity of the compression spring will drive the rotating plate to rotate and be perpendicular to the second connecting plate, thereby driving the L-shaped plate to rotate through the limiting rod to pop out the auxiliary supporting legs, so that the auxiliary supporting legs are tightly fitted to the top surface of the pier. The auxiliary supporting legs popped out on both sides can effectively increase the contact area between the two sides of the supporting block and the pier, thereby increasing the overall stability of the supporting block, thereby ensuring that the supporting block is more stable when supporting the main beam of the bridge erection machine and reducing safety hazards.

[0025] 2. This application is provided with a support assembly. First, the auxiliary frame is pulled out and placed in a vertical state so that the bottom of the auxiliary frame fits against the top of the bridge pier. The auxiliary frame is then supported and stabilized by a mortgage plate. The stabilized auxiliary frame can again increase the contact area between the support block and the bridge pier, thereby increasing the overall stability of the support block, thereby ensuring that the support block is more stable when supporting the main beam of the bridge erection machine and reducing safety hazards.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a bridge erection machine support leg.

[0034] Reference Figure 1 A bridge-building machine outrigger comprises a top plate 1, a supporting leg 2 is fixedly connected to the top of the top plate 1, a fixing plate 3 is fixedly connected to the inside of the supporting leg 2, two hydraulic telescopic rods 4 are symmetrically fixedly connected to the top of the fixing plate 3, the output ends of the two hydraulic telescopic rods 4 are both penetrated and fixedly connected with connecting rods 5, the bottom of the connecting rod 5 is fixedly connected to a bottom plate 6, the bottom of the bottom plate 6 is fixedly connected to a supporting block 7, the inside of the supporting block 7 is symmetrically installed with auxiliary components 8, and the bottom of the bottom plate 6 is symmetrically installed with supporting components 9.

[0035] When in use, first use the bridge-building machine to move the support leg 2 to the top of the pier, then start the hydraulic telescopic rod 4 to drive the connecting rod 5 to gradually descend, thereby driving the bottom plate 6 and the support block 7 to descend together through the connecting rod 5, until the bottom of the support block 7 is completely in contact with the top of the pier, then stop the operation of the hydraulic telescopic rod 4, and use the contact between the support block 7 and the pier to initially support and stabilize the bridge-building machine. When the support block 7 is completely and stably in contact with the pier, the auxiliary component 8 inside the support block 7 can be pulled out, and the contact area between the two ends of the support block 7 and the pier can be increased by pulling out the auxiliary component 8, and then the support component 9 can be pulled out. The overall width of the support block 7 can be changed by the support component 9, which effectively increases the contact area between the support block 7 and the pier, and increases the overall stability of the support block 7, thereby ensuring that the support block 7 is more stable when supporting the main beam of the bridge-building machine and reducing safety hazards.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The auxiliary component 8 includes an adjustment plate 81 symmetrically slidably connected to the inside of the support block 7, a fixed block 82 is symmetrically fixedly connected to the bottom of the adjustment plate 81, sliders 83 are fixedly connected to both sides of the adjustment plate 81, a connecting plate 1 84 is fixedly connected to the bottom of the fixed block 82, a connecting plate 2 85 is fixedly connected to the bottom of the fixed block 82, an L-shaped plate 86 is rotatably connected to one side of the connecting plate 1 84, an auxiliary leg 87 is fixedly connected to the bottom of the L-shaped plate 86, and a rotating plate 89 is rotatably connected to one side of the connecting plate 2 85, and a sliding groove 71 is opened on both sides of the inside of the support block 7, a stopper 72 is symmetrically fixedly connected to the inside of the support block 7, the slider 83 is slidably connected to the inside of the sliding groove 71, and an anti-slip pad 88 is fixedly connected to the bottom of the auxiliary leg 87;

[0037] Secondly, one end of the L-shaped plate 86 away from the auxiliary support leg 87 passes through a guide column 810 for rotation connection, one end of the rotating plate 89 passes through a guide column 811 for rotation connection, a limiting rod 812 is fixedly connected to the outer wall of the guide column 810, one end of the limiting rod 812 away from the guide column 810 is fixedly connected to the outer wall of the guide column 811, a rotating rod 813 passes through one side of the guide column 811 for rotation connection, a connecting column 814 is fixedly connected to the rotating rod 813, a hinge block 815 is fixedly connected to the bottom of the adjustment plate 81, a connecting column 816 is rotationally connected inside the hinge block 815, a compression spring 817 is fixedly connected to the connecting column 816, the other end of the compression spring 817 is fixedly connected to the connecting column 814, and a limiting block 818 is fixedly connected to the bottom of the fixed block 82.

[0038] When in use, after the bottom of the support block 7 is tightly fitted with the top of the pier, the adjustment plates 81 on both sides of the support block 7 can be pulled to move outward, thereby driving the connecting plate 1 84 and the connecting plate 2 85 at the bottom of the fixed block 82 to move outward together. When the rotating plate 89 on one side of the connecting plate 2 85 moves to the outside of the support block 7, the rotating plate 89 will lose the extrusion of the inner wall of the support block 7. According to the elasticity of the compression spring 817, the connecting column 1 814 and the rotating rod 813 will be pushed to rotate on the side of the guide column 2 811, thereby driving the rotating plate 89 to rotate and be perpendicular to the connecting plate 2 85. When the rotating plate 89 rotates, it will drive the guide column 81 on one side to rotate. The two guide columns 811 rotate together. When the guide column 811 rotates, it will pull the limit rod 812 to move. When the limit rod 812 moves, it will drive the L-shaped plate 86 to rotate through the guide column 810 until it fits with the limit block 818, thereby popping out the auxiliary support legs 87 at the bottom of the L-shaped plate 86, so that the auxiliary support legs 87 and the anti-slip pads 88 at the bottom are tightly fitted with the top surface of the pier. The auxiliary support legs 87 popped out on both sides can effectively increase the contact area between the two sides of the support block 7 and the pier, thereby increasing the overall stability of the support block 7, thereby ensuring that the support block 7 is more stable when supporting the main beam of the bridge erection machine and reducing safety hazards.

[0039] Reference Figure 1 and Figure 4 The support assembly 9 includes an articulated block 2 91 symmetrically fixedly connected to the bottom of the base plate 6, an auxiliary frame 92 is rotatably connected inside the articulated block 91, one side of the auxiliary frame 92 is symmetrically fixedly connected to an articulated block 3 93, one side of the support block 7 is symmetrically fixedly connected to an articulated block 4 94, an articulated block 4 94 is rotatably connected to a mortgage plate 95, one end of the mortgage plate 95 is penetrated by a threaded hole 96, and a bolt 97 is threadedly connected inside the articulated block 3 93.

[0040] During use, after the bottom of the support block 7 fits tightly against the top of the pier, first pull out the auxiliary frame 92 and put it in a vertical state, so that the bottom of the auxiliary frame 92 fits against the top of the pier, then unscrew the bolt 97, and then rotate the mortgage plate 95 to move the threaded hole 96 at one end of the mortgage plate 95 to the inside of the hinge block three 93, and then screw the taken out bolt 97 into the hinge block three 93 and pass through the threaded hole 96, so as to support and stabilize the auxiliary frame 92 through the mortgage plate 95. The stabilized auxiliary frame 92 can again increase the contact area between the support block 7 and the pier, thereby increasing the overall stability of the support block 7, thereby ensuring that the support block 7 is more stable when supporting the main beam of the bridge erection machine and reducing safety hazards.

[0041] The implementation principle of the supporting legs of a bridge erecting machine in this embodiment is as follows: when in use, the supporting legs 2 are first moved to the top of the pier by the bridge erecting machine, and then the hydraulic telescopic rod 4 is started to operate to drive the connecting rod 5 to gradually descend, thereby driving the bottom plate 6 and the supporting block 7 to descend together through the connecting rod 5, until the bottom of the supporting block 7 is completely attached to the top of the pier, and then the operation of the hydraulic telescopic rod 4 is stopped, and the bridge erecting machine is preliminarily supported and stabilized by the attachment of the supporting block 7 and the pier;

[0042] Secondly, when the bottom of the support block 7 is tightly fitted with the top of the pier, the adjustment plates 81 on both sides of the support block 7 can be pulled to move outward, thereby driving the connecting plate 1 84 and the connecting plate 2 85 at the bottom of the fixed block 82 to move outward together. When the rotating plate 89 on one side of the connecting plate 2 85 moves to the outside of the support block 7, the rotating plate 89 will lose the squeezing of the inner wall of the support block 7. According to the elasticity of the compression spring 817, the connecting column 1 814 and the rotating rod 813 will be pushed to rotate on the side of the guide column 2 811, thereby driving the rotating plate 89 to rotate and be perpendicular to the connecting plate 2 85. When the rotating plate 89 rotates, it will drive the guide column 2 on one side to rotate. When the guide column 811 rotates, the limit rod 812 is pulled to move. When the limit rod 812 moves, the L-shaped plate 86 is driven to rotate through the guide column 810 until it fits with the limit block 818, so that the auxiliary legs 87 at the bottom of the L-shaped plate 86 are ejected, so that the auxiliary legs 87 and the anti-skid pads 88 at the bottom are closely fitted with the top surface of the pier. The auxiliary legs 87 ejected on both sides can effectively increase the contact area between the two sides of the support block 7 and the pier, thereby increasing the overall stability of the support block 7, thereby ensuring that the support block 7 is more stable when supporting the main beam of the bridge erection machine, reducing safety hazards;

[0043] In addition, when the bottom of the support block 7 is tightly fitted with the top of the pier, the auxiliary frame 92 can be pulled out and placed in a vertical state, so that the bottom of the auxiliary frame 92 is fitted with the top of the pier, and then the bolt 97 is screwed out, and then the mortgage plate 95 is rotated, and the threaded hole 96 at one end of the mortgage plate 95 is moved to the inside of the hinge block three 93, and then the taken out bolt 97 is screwed into the hinge block three 93 and passed through the threaded hole 96, so that the auxiliary frame 92 is supported and stabilized by the mortgage plate 95. The stabilized auxiliary frame 92 can again increase the contact area between the support block 7 and the pier, thereby increasing the overall stability of the support block 7, thereby ensuring that the support block 7 is more stable when supporting the main beam of the bridge erection machine and reducing safety hazards.
