Description

Technical Field

[0001] This utility model relates to the field of auxiliary support technology, specifically to an auxiliary support for bridge bearing removal. Background Technology

[0002] Auxiliary supports for bridge bearing removal are temporary load-bearing structures specifically designed for bridge bearing replacement or removal operations. They are typically made of high-strength materials such as steel profiles and steel plates, and are usually arranged symmetrically between the beam and the foundation. Their core function is to temporarily bear the load of the beam during the removal of the old bearing, ensuring the stability of the beam structure and controllable settlement during the removal operation, and providing a safe and reliable working space for the cutting, separation and removal of the old bearing.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology: Common auxiliary support structures are too complex and are not detachable as a whole, which reduces their convenience and flexibility during transportation and use. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary support for bridge bearing removal, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary support for bridge bearing removal, comprising a base plate, a support assembly bolted to the top perimeter of the base plate, a top plate bolted to the top of the support assembly, and a connecting frame connected to the bottom ends of the top plate between the support assembly via bolts and nuts.

[0006] The beneficial effects of this utility model are as follows: by adding a second mounting hole and a second threaded slot, the support groove and support rod can be quickly installed and disassembled using fixing bolts. Furthermore, the height of the top plate can be adjusted using the first mounting hole and the first threaded slot, facilitating support for bridges of different heights. Additionally, the addition of the first and second mounting slots allows for the quick installation and disassembly of the connecting frame, and the horizontal position of the limiting plate can be adjusted, facilitating the limiting of bridges of different widths. This allows the device to be assembled and disassembled, facilitating transportation and increasing convenience while also enhancing flexibility in use.

[0007] To ensure that the fixing bolts can be installed without damaging the bridge: The top plate is further configured such that grooves are evenly provided at both ends of the top, and a first mounting groove is provided on the lower inner surface of the grooves.

[0008] By adopting the above technical solution, the fixing bolt can be passed through the first mounting groove. At this time, the upper part of the fixing bolt will be located in the groove and the height will be lower than the top end, thereby avoiding the situation where the top of the fixing bolt comes into contact with the bridge and causes the bridge to break.

[0009] To achieve effective support: Further features include: the bottom of the base plate has uniformly distributed anti-slip textures, and the top of the top plate is fitted with an elastic anti-slip pad.

[0010] By adopting the above technical solutions, the base plate can be made more slip-resistant through anti-slip texture, while the top can be made more slip-resistant through elastic anti-slip pads, thus providing effective support for the bridge and reducing damage to the bridge through the elastic anti-slip pads.

[0011] To enable the installation of the connector bracket: Further configuration: a second mounting groove is evenly provided on the inner lower surface of the connecting frame, a limiting plate is fixedly connected to the top of the connecting frame, and an elastic anti-slip pad is installed at one end of the limiting plate.

[0012] By adopting the above technical solution, the fixing bolt can be passed through the first mounting groove and then into the second mounting groove. The connecting frame can then be installed, and the horizontal position of the limiting plate can be adjusted. The nut can then be threaded onto the outside of the fixing bolt, thereby limiting the two ends of the bridge. At the same time, when limiting the two ends of the bridge, the anti-slip effect can be increased by elastic anti-slip pads, which can reduce damage to the bridge.

[0013] To enable adjustment of the ceiling height: Further configured as follows: the support assembly includes a support groove installed around the top of the base plate, with limit rods fixedly connected to both ends of the inner side of the support groove, a sliding rod slidably connected to the inner side of the support groove, a support rod fixedly connected to the top of the sliding rod, sliding grooves with the same external dimensions and structure as the limit rods being opened at both ends of the sliding rod, and first mounting holes being opened at the upper part of both sides of the support groove, and first threaded slots being evenly opened on both sides of the sliding rod.

[0014] By adopting the above technical solution, the sliding rod can slide inside the support groove, and the sliding groove can slide outside the limiting rod, ensuring stability during height adjustment. When the height is adjusted to a suitable level, the fixing bolt can be passed through the first mounting hole and into the first threaded groove hole, thereby limiting the sliding rod and ensuring effective support.

[0015] To enable rapid installation and removal of the support components: Further configuration: mounting blocks are fixedly connected to the lower parts of both sides of the support groove and the upper parts of both sides of the support rod, and a second mounting hole is provided at the top center of the mounting block, and a second threaded groove is provided at the joint between the top of the bottom plate and the bottom of the top plate and the second mounting hole.

[0016] By adopting the above technical solution, the fixing bolt can be passed through the second mounting hole and then into the second threaded groove hole, thereby installing the support groove on the top of the base plate and the support rod on the bottom of the top. Conversely, it can be disassembled.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0021] Please see Figures 1 to 3 An auxiliary support for bridge bearing removal includes a base plate 1, with support components 2 bolted to the top perimeter of the base plate 1, a top plate 3 bolted to the top of the support components 2, and connecting frames 6 connected to the bottom ends of the top plate 3 between the support components 2 via bolts and nuts.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, grooves 4 are evenly provided at both ends of the top of the top plate 3, and a first mounting groove 5 is provided on the lower inner surface of the grooves 4.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom of the base plate 1 is evenly textured with anti-slip patterns, and the top of the top plate 3 is fitted with an elastic anti-slip pad.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the lower inner surface of the connecting frame 6 is provided with a second mounting groove 7, and the top of the connecting frame 6 is fixedly connected to a limiting plate 8, with an elastic anti-slip pad installed at one end of the limiting plate 8.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the support assembly 2 includes a support groove 201 installed around the top of the base plate 1. Limiting rods 202 are fixedly connected to both ends of the inner side of the support groove 201. A sliding rod 203 is slidably connected to the inner side of the support groove 201. A support rod 204 is fixedly connected to the top of the sliding rod 203. Sliding grooves with the same external dimensions and structure as the limiting rods 202 are opened at both ends of the sliding rod 203. First mounting holes are opened on the upper part of both sides of the support groove 201, and first threaded slots are evenly opened on both sides of the sliding rod 203.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, mounting blocks 205 are fixedly connected to the lower parts of both sides of the support groove 201 and the upper parts of both sides of the support rod 204. A second mounting hole is provided at the top center of the mounting block 205, and a second threaded groove is provided at the joint between the top of the bottom plate 1 and the bottom of the top plate 3 and the second mounting hole.

[0027] The working process of this auxiliary support for bridge bearing removal is as follows: First, place the base plate 1 in the corresponding area. The anti-slip texture on the bottom of the base plate 1 will increase the anti-slip effect. Then, align the second mounting holes of the mounting blocks 205 on both sides of the support groove 201 with the second threaded slots on the top of the base plate 1. Then, pass the fixing bolts through the second mounting holes and into the second threaded slots to complete the installation of the support groove 201. Next, align the second mounting holes of the mounting blocks 205 on both sides of the support rod 204 with the second threaded slots on the bottom of the top plate 3. Then, pass the fixing bolts through the second mounting holes and into the second threaded slots to complete the installation of the support rod 204. Then, align the sliding groove of the sliding rod 203 with the limiting rod 202, and then push the sliding rod 203 so that the sliding rod 203 slides inside the support groove 201. Then, pass the fixing bolts through the first mounting groove 5 of the top plate 3 and the second mounting groove 7 of the connecting bracket 6 in sequence. Then, thread the nut onto the outside of the fixing bolt. At this time, it is not necessary to tighten the nut. Tighten the bolts to prevent the connecting bracket 6 from falling off. At this point, the upper part of the fixing bolt will be in the groove 4, and its height will not be higher than the top of the groove 4. Then, pull the limiting plates 8 at both ends outward so that the distance between the limiting plates 8 exceeds the width of the bridge. Then, move the sliding rod 203 upward so that the sliding rod 203 slides upward inside the support groove 201. At this time, the sliding groove will slide outside the limiting rod 202. Stop when the top of the top plate 3 contacts the bridge. Then, pass the fixing bolt through the first mounting hole into the first threaded groove hole to limit the sliding rod 203 and provide support. Then, move the limiting plates 8 at both ends inward until one end of the limiting plate 8 is in contact with the bridge. Then, tighten the nut. At this point, the bridge is supported. The anti-slip effect can be increased by the elastic anti-slip pad, which also prevents damage to the bridge. At this point, the bridge support can be removed.
