Therefore, they should not be construed as limitations on this utility model.

[0016] Example: Please see Figure 1-5 This utility model provides a technical solution: A novel foundation pit support replacement device includes two support plates 1. Each of the two support plates 1 has a storage cavity on its adjacent side. The storage cavity is used to store the connecting parts between the two support plates 1. When it is necessary to remove the connecting parts, the mounting plate 2 can be disassembled. The mounting plate 2 is installed inside each of the two storage cavities. The upper and lower ends of the two support plates 1 on their adjacent sides are provided with a first groove 3. The first groove 3 is threaded with a first bolt. The mounting plate 2 is fixedly connected to the support plate 1 by the first bolt. A first crossbar 4 is horizontally arranged between two support plates 1. Both ends of the first crossbar 4 are slidably connected to second crossbars 5. The other ends of the two second crossbars 5 are fixed with threaded rods 6. The outside of the two threaded rods 6 are threadedly connected to mounting blocks 7. The other side of the two mounting blocks 7 is fixed with evenly arranged insert rods 8. The telescopic length of the two second crossbars 5 inside the first crossbar 4 can be adjusted to change the distance between the two mounting blocks 7, so as to meet the installation needs of different pit widths. The front sides of both support plates 1 are provided with a second groove 9. The second groove 9 of the support plate 1 located at the left end is threaded with a second bolt. The side wall of the second groove 9 of the support plate 1 located at the right end is provided with a first threaded hole. The second bolt is adapted to the first threaded hole. When the two support plates 1 are not in use and need to be close together, they can be threaded together by the second bolt and the first threaded hole, thereby fixing the two support plates 1 together.

[0017] The upper and lower ends of the front and rear sides of the two support plates 1 are provided with third grooves 10. The upper third groove 10 is threaded with a third bolt, and the inner wall of the lower third groove 10 is provided with a second threaded hole. During use, if the pit is deep, multiple support plates 1 can be installed longitudinally. The installation method is to fix them by the third bolt and the second threaded hole.

[0018] A fourth groove 11 is provided in the middle of the front and rear sides of both support plates 1. A handling handle 12 is fixed inside the fourth groove 11, so that the two support plates 1 can be moved in position by means of the handling handle 12 after they are fixed.

[0019] The side walls of the two mounting plates 2 are provided with latching grooves 13. When it is necessary to open the mounting plate 2, the latching grooves 13 can be latched outward to separate the mounting plate 2 from the support plate 1.

[0020] The upper side of the first crossbar 4 is threaded with symmetrical limiting bolts, and the lower ends of the two limiting bolts are engaged with the upper side of the second crossbar 5.

[0021] The side walls of the two mounting plates 2 are provided with insertion holes, and the insertion rod 8 is adapted to the insertion holes.

[0022] Working principle: When the support replacement device is needed, firstly, remove the first crossbar 4, the second crossbar 5, the threaded rod 6, the mounting block 7, and the insert rod 8 from inside the two support plates 1. Insert the second crossbar 5 into the inside of the first crossbar 4 and fix it. Fix the second crossbar 5 between the threaded rod 6 and the mounting block 7. Fit the two support plates 1 with the inside sides of the pit. Adjust the length of the second crossbar 5 inside the first crossbar 4. Support and fix the first crossbar 4, the second crossbar 5, the threaded rod 6, the mounting block 7, and the insert rod 8 between the two support plates 1 to effectively support the pit. Similarly, when not in use, the first crossbar 4, the second crossbar 5, the threaded rod 6, the mounting block 7, and the insert rod 8 can be disassembled and stored inside the support plate 1. The two support plates 1 can be attached together and fixed by threading the second bolt to the first threaded hole, reducing the space occupied and making it more convenient to carry.
