Technical Field

[0001] This application relates to the field of pier clamp removal, specifically to a pier clamp removal device. Background Technology

[0002] In bridge design, column piers are a commonly used structural type. For simply supported bridges, the cap beam is a crucial component that connects the superstructure and substructure, transferring the loads from the superstructure to the substructure and foundation. The cap beam is the primary load-bearing structure. Variations in span, slope, bridge width, and vehicle load standards significantly impact the cap beam design, making it difficult to strictly adhere to standard and general drawings. The standardization of cap beam design is high, requiring extensive calculations; therefore, cap beam design is a critical part of bridge design.

[0003] In related technologies, during the construction of cap beams, the clamp method is usually used to erect the cap beam construction platform. The clamps on the cap beam piers are made of two clamp plates joined together, symmetrically on both sides.

[0004] However, after the cap beam construction is completed, the clamps need to be removed. During the removal process, the clamps need to be completely removed, which is difficult and the unstable unloading can easily damage and deform the clamps. Summary of the Invention

[0005] This application provides a device for removing pier clamps, which enables the clamp to be supported by a bottom load-bearing bracket, the clamp bolts to be loosened to a suitable position, and the clamp to be smoothly removed; it can increase the number of times the clamp can be used and reduce deformation caused by improper operation; moreover, the device has a simple structure, is easy to transport and operate, and can save labor and improve work efficiency while ensuring the safety of removing clamps.

[0006] This application provides a device for removing pier clamps, which includes:

[0007] A winding motor, wherein two traction ropes are sleeved on the outer wall of the output end of the winding motor, and the two traction ropes are wound in the same direction;

[0008] The bottom load-bearing bracket is fixed to the two traction ropes, and the bottom load-bearing bracket has a pier column through hole, and the bottom load-bearing bracket is used to be sleeved on the outer wall of the pier column through the pier column through hole;

[0009] The winding motor can drive the bottom load-bearing bracket to rise or fall along the outer wall of the pier column.

[0010] In one embodiment, the pier clamp removal device further includes:

[0011] A top-bearing bracket is used to fix the top of the cover beam, and the winding motor is installed on the top of the cover beam.

[0012] In one embodiment, the top support bracket is fixed to two guide pulleys, and the two guide pulleys correspond one-to-one with the two traction ropes and are slidably connected to the corresponding traction ropes.

[0013] In one embodiment, the top of the bottom load-bearing bracket is fixed with two lifting lugs, which correspond one-to-one with two diagonal corners of the bottom load-bearing bracket and are fixed at the corresponding diagonal corners.

[0014] In one embodiment, the number of lifting lugs is four, and the four lifting lugs are distributed around the top of the bottom load-bearing bracket.

[0015] In one embodiment, the bottom support bracket includes:

[0016] Four first I-beams are connected end to end to form the through hole of the pier column.

[0017] In one embodiment, the bottom support bracket further includes:

[0023] When removing clamps, first determine the appropriate size of the bottom support bracket based on the pier column dimensions. Install the bottom support bracket through the pier column's through-hole. A crane lifts the winding motor above the completed cap beam, secures it, and lowers the traction rope of the winding motor to connect with the bottom support bracket. The bottom support bracket is then lifted to support the clamp to be removed. The clamp bolts are loosened to a suitable position, allowing the clamp to slide freely up and down. The bottom support bracket is then lowered to the ground using the winding motor, quickly completing the clamp removal. This method eliminates the need for complete removal of the clamp; it allows the clamp to be supported by the bottom support bracket, the bolts loosened to a suitable position, and the clamp smoothly unloaded. This increases the number of times the clamp can be used and reduces deformation caused by improper operation. Furthermore, the device has a simple structure, is easy to transport and operate, and ensures safe clamp removal while saving labor and improving work efficiency. Attached Figure Description

[0031] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] It's important to understand that column piers are a commonly used structural type in bridge design. For simply supported bridges, the cap beam is a crucial component that connects the superstructure and substructure, transferring the loads from the superstructure to the substructure and foundation. The cap beam is the primary load-bearing structure. Variations in span, slope, bridge width, and vehicle load standards significantly impact the cap beam design, making it difficult to strictly adhere to standard and general drawings. Cap beam design requires a high degree of standardization and extensive calculations, making it a critical part of bridge design.

[0033] During the construction of the cap beam, the clamp method is usually used to erect the construction platform. The clamps on the cap beam piers are made of two clamp plates joined together, symmetrically on both sides. However, after the cap beam construction is completed, the clamps need to be removed. During the removal process, it is often encountered that the clamps are too tight, and when the clamps are removed, they will rub against the concrete of the pier, causing concrete damage and deformation of the clamps.

[0034] This application provides a device for removing pier clamps, which allows the clamp to be supported by a bottom load-bearing bracket, the clamp bolts to be loosened to a suitable position, and the clamp to be smoothly removed. This increases the number of times the clamp can be used and reduces deformation caused by improper operation. Moreover, the device has a simple structure, is easy to transport and operate, and can save labor and improve work efficiency while ensuring the safety of clamp removal.

[0035] like Figure 1 and Figure 2 As shown in the figure, this application provides a pier clamp removal device, which may include: a winding motor 1, the outer wall of which is fitted with two traction ropes 2, the two traction ropes 2 being wound in the same direction; a bottom support bracket 3, which is fixed to the two traction ropes 2, and the bottom support bracket 3 has a pier through hole 4, which is used to fit onto the outer wall of the pier 9 through the pier through hole 4; the winding motor 1 can drive the bottom support bracket 3 to rise or fall along the outer wall of the pier 9.

[0036] For example, see specific examples. Figure 1 The output end of the winding motor 1 is fitted with two traction ropes 2, which can be steel wire ropes to ensure their load-bearing capacity. See details [link to relevant documentation]. Figure 2 The two traction ropes 2 have the same traction direction. That is, when the winding motor 1 rotates in the forward or reverse direction, it will drive the two traction ropes 2 to wind or unwind, thereby driving the bottom load-bearing bracket 3 connected to it to rise or fall. The bottom load-bearing bracket 3 can be installed on the outer wall of the pier 9 through the pier through hole 4.

[0037] Specifically, refer to Figure 4 and Figure 5When removing the clamp 91, the dimensions of the bottom support bracket 3 are first determined according to the dimensions of the pier column 9. The bottom support bracket 3 is pre-installed through the pier column through hole 4. The crane lifts the winding motor 1 to the top of the already poured cap beam 8 and places it securely. The winding motor 1 lowers the traction rope 2 to connect with the bottom support bracket 3, and lifts the bottom support bracket 3 to support the clamp 91 to be removed. The clamp bolts are loosened to a suitable position, allowing the clamp 91 to slide freely up and down. The bottom support bracket 3 is then lowered to the ground position by the winding motor 1, completing the removal of the clamp 91. This method achieves the goal of supporting the clamp 91 with the bottom support bracket 3, loosening the clamp bolts to a suitable position, and smoothly unloading the clamp 91. It can increase the number of times the clamp 91 can be used and reduce deformation caused by improper operation. Moreover, its device structure is simple, easy to transport and operate, and can save labor and improve work efficiency while ensuring the safety of removing the clamp 91.

[0038] In one embodiment, such as Figure 2 As shown, the pier clamp removal device may further include: a top-bearing bracket 5, which is used to fix the top of the cap beam 8, and the winding motor 1 is installed on the top of the cap beam 8. For example, the top-bearing bracket 5 ensures that the winding motor 1 is firmly fixed to the top of the cap beam 8, guaranteeing smooth subsequent winding and unwinding operations. Furthermore, the length of the top-bearing bracket 5 can exceed the width of the cap beam 8, creating a certain gap between the traction rope 2 and the side wall edge of the cap beam 8, preventing friction between the traction rope 2 and the side wall edge of the cap beam 8.

[0039] In one embodiment, such as Figure 2 As shown, the top support bracket 5 is fixed to two guide pulleys 51, each guide pulley 51 corresponding to one of the two traction ropes 2, and slidably connected to the corresponding traction rope 2. For example, the guide pulleys 51 are fixed to the top of the top support bracket 5, and the guide pulleys 51 can change the traction direction of the traction ropes 2, facilitating the fixing of the two traction ropes 2 at both ends of the top support bracket 5. Furthermore, after the traction ropes 2 change direction via the guide pulleys 51, they pass through the top support bracket 5 and are fixed to the bottom support bracket 3 below it.

[0040] In one embodiment, such as Figure 3 As shown, the top of the bottom support bracket 3 is fixed with two lifting lugs 6. The two lifting lugs 6 correspond one-to-one with the two diagonal corners of the bottom support bracket 3 and are fixed at the corresponding diagonal positions. For example, the first lifting lug 6 can be fixed at the upper left corner of the bottom support bracket 3, and the second lifting lug 6 can be fixed at the upper right corner of the bottom support bracket 3, so that the traction rope 2 can exert a uniform tension on the bottom support bracket 3, ensuring that the bottom support bracket 3 remains as horizontal as possible during suspension.

[0041] In one embodiment, such as Figure 3 As shown, there are four lifting lugs 6, which are distributed around the top of the bottom support bracket 3. Alternatively, one lifting lug 6 can be fixed around the top of the bottom support bracket 3, ensuring that workers can select two diagonally distributed lifting lugs 6 according to the actual operating space to connect and fix the traction rope 2 to the bottom support bracket 3.

[0042] In one embodiment, such as Figure 3 As shown, the bottom load-bearing bracket 3 includes four first I-beams 31, which are connected end-to-end to form the pier column through hole 4. For example, the bottom load-bearing bracket 3 can be connected by four first I-beams 31 to form an integral frame, and the four first I-beams 31 connected end-to-end to form the pier column through hole 4. On the one hand, the bottom load-bearing bracket 3 has a simple structure and reasonable design; on the other hand, it also ensures the lightweight design of the bottom load-bearing bracket 3, reducing construction difficulty.

[0043] In one embodiment, such as Figure 3 As shown, the bottom load-bearing bracket 3 further includes two second I-beams 32, which fix the two opposing inner sidewalls of the pier column through hole 4. For example, two second I-beams 32 can be fixed between the front and rear inner sidewalls of the pier column through hole 4 to enhance the structural strength of the bottom load-bearing bracket 3. This also facilitates the subsequent laying of a template between the second I-beams 32 and the first I-beams 31, providing construction workers with space for work.

[0044] In one embodiment, such as Figure 3 As shown, the four first I-beams 31 are detachably fixed together. For example, the detachable fixing of the four first I-beams 31 facilitates transportation according to the construction site and makes assembly easier during construction.

[0045] Furthermore, the four first I-beams 31 can be assembled together by fixing bolts, and multiple bolt through holes are opened in the length direction of the first I-beams 31. This allows the size of the pier through hole 4 to be adjusted according to the position of the bolt through hole, thereby meeting the needs of piers 9 of different sizes and specifications.

[0046] In one embodiment, such as Figure 3 As shown, directional pulleys 7 are fixed to both inner walls of the pier through hole 4. For example, directional pulleys 7 can be fixed to both the front and rear inner walls of the pier through hole 4, and the directional pulleys 7 contact the side walls of the pier 9, which can reduce the impact between the first I-beam 31 and the pier and improve the problem of damage and deformation of the bottom load-bearing bracket 3.

[0047] In one embodiment, such as Figure 3As shown, directional pulleys 7 are fixed on the four inner sidewalls of the pier column through-hole 4. Exemplarily, directional pulleys 7 can be fixed on the four inner sidewalls of the pier column through-hole 4, and the directional pulleys 7 are in contact with the sidewall of the pier column 9, which can reduce the impact degree between the first I-beam 31 and the pier column 9 and improve the problem of damage and deformation of the bottom bearing bracket 3.

[0048] In summary, the bottom bearing bracket 3: It consists of a first I-beam 31 and a second I-beam 32 to form a "mu" - shaped bracket, which is connected by fixing bolts, can be freely disassembled and assembled, and the size of the bracket can be freely adjusted through the position of the reserved bolt through-holes to be applicable to pier columns 9 of different sizes, and lifting lugs 6 are provided at all four corners. The top bearing bracket 5: It consists of a whole steel panel, on which a winding motor 1 is installed, and guide pulleys 51 are provided on both sides to redirect the traction rope 2, and the bottom bearing bracket 3 below is connected through the traction rope 2. The hooping 91 can be supported by the bottom bearing bracket 3, and the hooping bolts can be loosened to an appropriate position to smoothly lower the hooping 91. The usage times of the hooping 91 can be increased, and the deformation caused by improper operation can be reduced. Its structure is simple, convenient for handling and operation, and can save labor and improve work efficiency while ensuring the safety of removing the hooping 91.
