Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe pile top pipe balanced reinforcement, in particular to a long-distance top pipe balanced reinforcement device. Background Art

[0002] In order to reliably support and protect the ditch foundation pit during ditch construction, it is necessary to fix steel pipe piles in the ditch. After the steel pipe piles are laid, jacking pipes will be installed between the steel pipe piles to ensure the structural strength between the steel pipe piles.

[0003] At present, the jacking pipe used for steel pipe pile reinforcement is mainly used to directly connect the two ends of the jacking pipe with the pre-fixed base plate on the steel pipe pile by bolts. Although the steel pipe pile can be reliably fixed when in use under the above installation method, the reinforcement support distance between the steel pipe piles is large, resulting in a long length of the jacking pipe used for support. During installation, the long-distance jacking pipe is easy to tilt due to the lack of control of balance, which causes the jacking pipe to tilt between the steel pipe piles when supporting.

[0008] Furthermore, four ear plates are symmetrically welded on both side walls of the fixing plate, and each ear plate has a hole for external bolts to pass through.

[0009] By adopting the above technical solution, the ear plate cooperates with the external bolts to achieve reliable fixation of the fixing plate at the installation base plate on the steel pipe pile.

[0010] Furthermore, an arc-shaped strip bracket is provided on the top of the support plate.

[0012] Furthermore, the U-shaped connecting plate is bolted to the supporting plate, and the diagonal brace is rotatably connected to the U-shaped connecting plate.

[0013] By adopting the above technical solution, it is possible to ensure that the diagonal support rod can be easily rotated relative to the U-shaped connecting plate, thereby facilitating the carrying and transportation of the device before installation.

[0019] By adopting the above technical solution, the sleeve can be conveniently raised and lowered by rotating the threaded rod with the help of the hand wheel, so as to achieve rapid insertion of the sleeve into the pin.

[0020] Furthermore, the guide slide block is slidably connected to the guide slide groove, and the height of the guide slide groove is smaller than the height of the fixed plate.

[0021] By adopting the above technical solution, the cooperation between the guide sliding block and the guide sliding groove can ensure the stable sliding of the sleeve during adjustment.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] In order to solve the problem that the jacking pipe used for the reinforcement of the current steel pipe pile is mainly connected to the base plate pre-fixed on the steel pipe pile by bolts, although the steel pipe pile can be reliably fixed in use under the above installation method, the reinforcement support distance between the steel pipe piles is large, resulting in a long length of the jacking pipe used for support, and the long-distance jacking pipe is easy to be skewed due to the lack of control of balance during installation, thereby causing the jacking pipe to be skewed between the steel pipe piles during support. The utility model is used to pre-install the fixing plate on the installation base plate reserved on the steel pipe pile after paving, and then move the plug sleeve to the pin on the plug rod to ensure the horizontal placement of the support plate, and then only need to place the jacking pipe for the steel pipe pile support reinforcement on the support plate, so as to ensure that the jacking pipe is quickly connected and fixed with the installation base plate on the steel pipe pile in a horizontal state. Since the balance of the jacking pipe after installation is effectively ensured by the pre-support method under the above installation method, the jacking pipe is more stable when used, and the skew phenomenon of the steel pipe pile when supported after installation is avoided.

A plug sleeve 5 is arranged below the plug pin 3, and two guide sliders 13 are symmetrically fixed to the back of the plug sleeve 5. An L-shaped fixing plate 4 is arranged on one side of the plug sleeve 5, and a guide slide groove 6 is provided on the fixing plate 4 at a position cooperating with the guide slider 13. The bottom end of the plug sleeve 5 A threaded rod 9 is connected to the middle part through a rotating sleeve 10. Under the action of the connecting sleeve, the threaded rod 9 can be easily rotated relative to the socket 5. A hand wheel 8 is fixed to the bottom end of the threaded rod 9. By rotating the threaded rod 9 with the help of the hand wheel 8, the socket 5 can be easily raised and lowered, so as to realize the rapid insertion of the socket 5 into the pin 3. After the socket 5 cooperates with the pin 3, the top pipe for supporting the steel pipe pile can be reliably supported under the action of the diagonal support rod 2, the U-shaped connecting plate 11 and the supporting support plate 1, so as to ensure the balance and support strength of the top end of the steel pipe pile after installation.

[0031] like Figure 1-Figure 2 As shown, in this embodiment, four ear plates 7 are symmetrically welded on the two side walls of the fixing plate 4, and each ear plate 7 has a hole for the external bolts to pass through. The ear plates 7 cooperate with the external bolts to realize the reliable fixation of the fixing plate 4 at the base plate installed on the steel pipe pile. An arc-shaped long strip bracket 12 is also provided on the top of the support bracket 1. The bracket 12 can ensure that there is sufficient contact area between the support bracket 1 and the jacking pipe supported by the steel pipe pile, so as to ensure the horizontality of the jacking pipe before the jacking pipe is installed, and continue to effectively support the jacking pipe after the jacking pipe is installed to ensure the supporting strength of the jacking pipe after installation.

[0032] like Figure 1-Figure 2 As shown, in this embodiment, the U-shaped connecting plate 11 is bolted to the supporting bracket 1, and the diagonal support rod 2 is rotatably connected to the U-shaped connecting plate 11, which can ensure the convenient rotation of the diagonal support rod 2 relative to the U-shaped connecting plate 11, and facilitate the carrying and transportation of the device before installation. The pin 3 is formed on the diagonal support rod 2, and the cross-sectional size of the pin 3 matches the cross-sectional size of the socket 5, which can ensure the stable insertion and fixation of the pin 3 and the socket 5. The rotating sleeve 10 is welded to the socket 5, and the threaded rod 9 is rotatably connected to the rotating sleeve 10.

The handwheel 8 is welded to the threaded rod 9, and the handwheel 8 is located on the lower side of the fixed plate 4. The guide slider 13 is slidably connected to the guide slot 6. The height of the guide slot 6 is less than the height of the fixed plate 4. The cooperation of the guide slider 13 and the guide slot 6 can ensure the stable sliding of the socket 5 during adjustment.
