Description

Technical Field

[0001] This utility model relates to the field of cofferdam demolition frame technology, and more specifically, to an adjustable demolition frame for imported slope cofferdam demolition. Background Technology

[0002] In the dismantling of cofferdams on the inlet slope of water conservancy projects, the dismantling frame is a core auxiliary structure that supports construction equipment and ensures operational safety. It needs to be flexibly adapted according to the actual size of the cofferdam dismantling area and the construction scenario.

[0003] The existing dismantling frames used for imported slope cofferdam demolition are mostly rigid frames of fixed specifications, assembled into rectangular structures by welding or non-adjustable bolts. This connection method has shortcomings in practical use. First, the fixed structure dismantling frame needs to be transported as a whole, occupying a large space, and is difficult to assemble and adapt quickly in complex slope environments, failing to meet the space adjustment needs of different dismantling stages. Second, the same dismantling frame is difficult to adapt to cofferdam demolition operations of different sizes, requiring customized frames for different projects, increasing equipment costs and inventory pressure. Utility Model Content

[0004] This utility model proposes an adjustable demolition frame for dismantling imported slope cofferdams. Through the sliding connection between the corner plate and the transverse and longitudinal support frame, as well as the telescopic structure of the telescopic sleeve and telescopic arm, the size of the demolition frame can be adjusted, enabling the same demolition frame to perform demolition operations on cofferdams of different sizes.

[0005] This utility model proposes an adjustable dismantling frame for dismantling inlet slope cofferdams, comprising two transverse support frames, two longitudinal support frames, and multiple corner plates. The two transverse support frames and two longitudinal support frames are spliced ​​into a rectangular structure. The two ends of each corner plate are slidably connected to the transverse support frames and the longitudinal support frames, respectively. Fixed plates are fixedly connected to the top and bottom of each corner plate. First sliding holes are opened at the top and bottom of each end of the transverse support frames and the longitudinal support frames. Second sliding holes are opened at the top and bottom of each corner plate. Fastening plates are slidably connected in the first sliding holes at both ends of the transverse support frames and the longitudinal support frames. The top and bottom of each fastening plate pass through the second sliding holes on the corner plate and extend to their outer sides. The fastening plates are fixed to the fixed plates by a locking mechanism.

[0006] Preferably, the locking mechanism includes a locking screw, the end of which passes through the fixing plate and the fastening plate and extends to their outer side. A second locking nut is threaded onto the outer wall of the locking screw. The second locking nut abuts against the fastening plate, causing the fastening plate to press against the end of the first sliding hole, and pressing the ends of the transverse support frame and the longitudinal support frame against the corner plate.

[0007] Preferably, the outer wall of the locking screw is threaded with a first locking nut, which, together with a second locking nut, clamps and fixes the fastening plate.

[0008] Preferably, a first rotating shaft is fixedly connected to the top of each of the two transverse support frames, and a telescopic sleeve is rotatably connected to the outer circumference of each of the first rotating shafts.

[0009] Preferably, a second rotating shaft is fixedly connected to the top of each of the two longitudinal support frames, and a telescopic arm is rotatably connected to the outer wall of each of the second rotating shafts.

[0010] Preferably, the telescopic sleeve has a telescopic hole at its end, and both the telescopic sleeve and the telescopic arm have multiple adjustment holes at their tops.

[0011] Preferably, the dismantling frame further includes multiple fastening bolts, the telescopic arm is slidably connected to the inner wall of the telescopic hole, and the fastening bolts fix the telescopic sleeve to the telescopic arm through the adjustment hole.

[0012] The beneficial effects of this utility model, achieved through the above technical solution, are as follows: 1. The dismantling frame is assembled into a rectangular structure by two transverse support frames and two longitudinal support frames, and is slidably connected to the transverse and longitudinal support frames by corner plates. This allows the dismantling frame to be disassembled before transportation. Compared with the overall handling of traditional fixed structure dismantling frames, this disassembly method reduces the transportation volume. The position and angle of the transverse and longitudinal support frames can be adjusted by sliding corner plates to quickly complete the assembly of the dismantling frame to adapt to the space requirements of different dismantling stages. Through the sliding connection of the corner plates to the transverse and longitudinal support frames, as well as the telescopic structure of the telescopic sleeve and telescopic arm, the size of the dismantling frame can be adjusted, enabling the same dismantling frame to carry out dismantling operations on cofferdams of different sizes.

[0013] 2. The locking screw is threaded through the fixed plate and the fastening plate, and the second locking nut is threaded on the outer wall of the locking screw so that it abuts against the fastening plate, thereby squeezing the end of the first sliding hole and pressing the ends of the transverse support frame and the longitudinal support frame into the corner plate. This fixing method can ensure that after the size of the dismantling frame is adjusted, the components are tightly connected and will not be displaced or loosened due to external forces.

[0014] 3. The telescopic sleeve and telescopic arm further enhance the stability and strength of the connection between the transverse support frame and the longitudinal support frame. Attached Figure Description

Detailed Implementation

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In this utility model, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, an adjustable dismantling frame for dismantling an imported slope cofferdam includes two transverse support frames 1, two longitudinal support frames 2, and multiple corner plates 11. The two transverse support frames 1 and two longitudinal support frames 2 are spliced ​​into a rectangular structure. The two ends of the corner plates 11 are slidably connected to the transverse support frames 1 and the longitudinal support frames 2, respectively. Fixed plates 12 are fixedly connected to the top and bottom of the corner plates 11. First sliding holes 10 are opened at the top and bottom of both ends of the transverse support frames 1 and the longitudinal support frames 2. Second sliding holes 13 are opened at the top and bottom of the corner plates 11. Fastening plates 14 are slidably connected in the first sliding holes 10 at both ends of the transverse support frames 1 and the longitudinal support frames 2. The top and bottom of the fastening plates 14 pass through the second sliding holes 13 on the corner plates 11 and extend to their outer sides. The fastening plates 14 are fixed to the fixed plates 12 by a locking mechanism.

[0020] The two transverse support frames 1 and two longitudinal support frames 2 are spliced ​​together to form a rectangular structure, and the corner plate 11 is slidably connected to the transverse and longitudinal support frames, allowing the dismantling frame to be disassembled into multiple parts during transportation. Compared with traditional fixed structure dismantling frames that need to be transported as a whole, this design reduces the transportation volume and lowers the difficulty and cost of transportation.

[0021] This splicing and sliding connection method allows the demolition frame to be quickly assembled and adapted in complex slope environments. Construction workers can flexibly adjust the positions of the transverse support frame 1 and the longitudinal support frame 2 according to the actual terrain and cofferdam shape, and change the size and angle of the frame by sliding corner plates 11 to meet the spatial adjustment needs of different demolition stages.

[0022] Due to its adjustable size, the same dismantling frame can adapt to the dismantling of cofferdams of different sizes, eliminating the need to customize special frames for different projects. This effectively reduces equipment costs and inventory pressure.

[0023] like Figure 5 and Figure 6 As shown, the locking mechanism includes a locking screw 15. The end of the locking screw 15 passes through the fixing plate 12 and the fastening plate 14 and extends to their outer side. The outer wall of the locking screw 15 is threaded with a second locking nut 17. The second locking nut 17 abuts against the fastening plate 14, causing the fastening plate 14 to press against the end of the first sliding hole 10, and pressing the ends of the transverse support frame 1 and the longitudinal support frame 2 against the corner plate 11.

[0024] The locking screw 15 passes through the fixing plate 12 and the fastening plate 14, and the second locking nut 17 is threaded onto the outer wall of the locking screw 15 so that it abuts against the fastening plate 14, thereby squeezing the end of the first sliding hole 10 and pressing the ends of the transverse support frame 1 and the longitudinal support frame 2 against the corner plate 11. This fixing method can ensure that after the size of the dismantling frame is adjusted, the components are tightly connected and will not be displaced or loosened due to external forces.

[0025] like Figure 5 and Figure 6 As shown, the outer wall of the locking screw 15 is threaded with a first locking nut 16, which, together with the second locking nut 17, clamps and fixes the fastening plate 14.

[0026] The first locking nut 16, together with the second locking nut 17, clamps and fixes the fastening plate 14, forming a double fastening effect. This design further increases the friction and stability of the connection part.

[0027] During installation and disassembly, the first locking nut 16 can be initially fixed to facilitate adjustment of the position of the fastening plate 14, and then the second locking nut 17 can be tightened for final fastening.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, each of the two transverse support frames 1 has a first rotating shaft 3 fixedly connected to its top, and a telescopic sleeve 4 is rotatably connected to the outer circumference of each of the first rotating shaft 3. Each of the two longitudinal support frames 2 has a second rotating shaft 7 fixedly connected to its top, and a telescopic arm 8 is rotatably connected to the outer wall of each of the second rotating shaft 7. The telescopic sleeve 4 has a telescopic hole 5 at its end, and both the telescopic sleeve 4 and the telescopic arm 8 have multiple adjustment holes 6 at their tops. The dismantling frame also includes multiple fastening bolts 9. The telescopic arm 8 is slidably connected to the inner wall of the telescopic hole 5, and the fastening bolts 9 fix the telescopic sleeve 4 and the telescopic arm 8 together through the adjustment holes 6.

[0029] The telescopic sleeve 4 and telescopic arm 8 can further enhance the stability and strength of the connection between the transverse support frame 1 and the longitudinal support frame 2.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
