Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a tool for a foundation pit support replacement component that is easy to install and disassemble. Background Technology
[0002] In modern construction engineering, foundation pit construction is one of the key links in infrastructure development. With the rapid development of urban construction, the scale and depth of foundation pits are constantly increasing, placing higher demands on the stability and reliability of foundation pit support structures. As an important component of the foundation pit support system, the construction quality and efficiency of foundation pit replacement supports directly affect the safety and progress of the entire foundation pit project. Traditional foundation pit replacement support components have many problems in the installation and dismantling process. First, due to the limited working space in the foundation pit, the use of large machinery is restricted, which often requires a large amount of manual operation for the installation and dismantling of the replacement support components. This is not only labor-intensive but also inefficient. Therefore, it is necessary to design a set of tools for foundation pit replacement support components that facilitate installation and dismantling.
[0003] Existing support replacement components are complex in their connection methods, usually requiring a large number of bolts, nuts and other connectors for fixing. The installation and disassembly process is time-consuming and labor-intensive, and the fixation is low. There is a lack of effective auxiliary tools during installation and disassembly, making it difficult to achieve accurate positioning and rapid installation, which leads to a longer construction period, as well as increased construction costs and safety risks.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described 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.
[0039] Example 1: Please refer to Figures 1 to 10 :
[0040] This utility model proposes a matching tool for a foundation pit support replacement component that is easy to install and disassemble, including: a base 1;
[0041] Four sets of fixed supports 11 are fixed on the base 1. The lower end of each fixed support 11 is a pyramidal structure. The fixed supports 11 are hollow and have through holes at both the front and rear ends. Two sets of transmission seats 111 are bolted inside each fixed support 11. The two sets of transmission seats 111 are respectively bolted to the inner walls of the front and rear ends of the fixed support 11. Each set of transmission seats 111 has a movable toothed rod 113 inside. The two sets of transmission seats 111 are connected by... The transmission rod 112 has two sets of gears fixed on it. Both sets of gears are located inside the transmission seat 111. The two sets of gears on the transmission rod 112 mesh with the tooth grooves on the two sets of first tooth groove rods 113. The two sets of first tooth groove rods 113 are located in the through holes at the front and rear ends of the fixed support 11. The upper end of the transmission rod 112 is set as a hexagonal prism. The upper end of the transmission rod 112 is fitted with a fitting plate 114. A handle 115 is fixed on the fitting plate 114.
[0042] In this embodiment of the disclosure,
[0043] Two sets of hinge plates 2 are hinged to the base 1. A mounting bracket 21 is bolted between the two sets of hinge plates 2. A hydraulic rod 22 is connected between each set of hinge plates 2 and the base 1. A motor mount 211 is bolted to the mounting bracket 21. A motor 213 is bolted to the motor mount 211. A lead screw 212 is mounted on the mounting bracket 21 via bearings. The lower end of the lead screw 212 is connected to the output shaft of the motor 213. Two sets of sliding grooves are provided on the mounting bracket 21. A sliding plate 23 slides on the mounting bracket 21. Two sets of mating parts are fixed to the lower end of the sliding plate 23. The two sets of seats 231 slide in the two sets of sliding grooves on the mounting frame 21 respectively. The lower end of the sliding plate 23 is fixed with a threaded seat 232, which is threadedly engaged with the lead screw 212. Its function is to realize the adjustability of the angle and position of the mounting frame 21 relative to the base 1 through the two sets of hinge plates 2 hinged on the base 1 and the connected hydraulic rod 22. The motor 213 serves as the power source to drive the lead screw 212 to rotate, thereby driving the threaded seat 232 threadedly engaged with the lead screw 212 to move up and down, thus realizing the lifting function of the sliding plate 23.
[0044] Example 2, based on Example 1,
[0045] A mounting base 24 is bolted to the upper end of the sliding plate 23. The mounting base 24 has two sets of arc-shaped through slots. A movable seat 241 is mounted on the mounting base 24. The movable seat 241 has two sets of threaded holes. Connecting bolts 243 are installed in the two sets of arc-shaped through slots on the mounting base 24. Washers 242 are fitted on the connecting bolts 243. The two sets of connecting bolts 243 are threaded into the two sets of threaded holes on the movable seat 241. A worm gear ring 244 is mounted on the mounting base 24. A worm 245 is mounted on the lower end of the movable seat 241 through a bearing. The worm 245 meshes with the worm gear ring 244. Its function is to achieve a small and precise angle change of the movable seat 241 relative to the mounting base 24 by rotating the worm 245. This meets the needs of some foundation pit projects with high requirements for support angle accuracy, further improves the practicality and functionality of the support replacement component, and helps to improve the quality and safety of foundation pit support.
[0046] Example 3, based on Examples 1 and 2,
[0047] A frame seat 25 is bolted to the movable seat 241. A second hydraulic rod 251 is fixed to the frame seat 25. A support plate 252 is fixed to the piston rod of the second hydraulic rod 251. Four sets of second gear rods 2521 are fixed to the lower end of the support plate 252. A first rod 253, a second rod 254, and a third rod 255 are mounted on the frame seat 25 via bearings. The first rod 253 meshes with the second rod 254 and the third rod 255 via bevel gears. Two sets of gears are fixed to both the second rod 254 and the third rod 255. The gears on the wheel, rod 254, and rod 255 respectively mesh with the teeth on the four sets of second-tooth rods 2521. Their function is to provide adjustable support force for the pallet 252 by utilizing the telescopic characteristics of the second hydraulic rod 251 to adapt to the support force requirements under different working conditions, and to ensure that the support replacement assembly can effectively support the foundation pit structure. When rod 253 rotates, it can simultaneously drive the four sets of second-tooth rods 2521 to perform synchronous extension or retraction actions, thereby improving the stability of the pallet 252.
[0048] The working principle of this embodiment is as follows: During the installation of the foundation pit support replacement assembly, the base 1 is first placed in the predetermined position. The interlocking plate 114 is rotated by the handle 115, which in turn drives the transmission rod 112 to rotate. The gear on the transmission rod 112 drives the first toothed rod 113 in the two sets of transmission seats 111 to extend, so that the two sets of first toothed rods 113 are inserted laterally into the soil, thereby improving the fixation of the base 1 and ensuring the foundation stability of the entire support replacement assembly. Next, the first hydraulic rod 22 is activated. Its extension and retraction action can adjust the angle between the hinge plate 2 and the base 1, thereby driving the mounting frame 21 to reach a suitable working position and angle to adapt to the actual working conditions of different foundation pits. Subsequently, the motor 213 is turned on. The output shaft of the motor 213 drives the lead screw 212 to rotate. Since the lead screw 212 and the lower end of the sliding plate 23 are connected, the motor 212 rotates. The threaded seat 232 is threadedly engaged, and the mating seat 231 of the sliding plate 23 slides along the groove on the mounting frame 21. This allows the sliding plate 23 to move smoothly up and down on the mounting frame 21, adjusting the mounting seat 24 and its accessories mounted on the upper end of the sliding plate 23 to the required height position. If it is necessary to adjust the angle of the movable seat 241 on the mounting seat 24, the worm 245 can be rotated, and the worm 245 meshes with the worm wheel ring 244 on the mounting seat 24, thereby achieving a fine adjustment of the angle of the movable seat 241 relative to the mounting seat 24 to meet the support requirements in different directions. When the support plate 252 is needed for support operations, the second hydraulic rod 251 is activated, and the piston rod of the second hydraulic rod 251 pushes the support plate 252 to move towards the target support position, supporting the wall of the pit through the support plate 252.
