[0001] This application relates to the field of roadbed deep pit support technology, specifically a roadbed deep pit support device. Background Technology

[0002] Municipal infrastructure projects refer to civil engineering, pipeline, and equipment installation projects for urban roads, public transportation, water supply, drainage, gas, heating, landscaping, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities, and ancillary facilities. During municipal road construction, deep pits are often excavated for roadbed work. After the pit excavation is completed, reinforcement structures are usually installed within the pit to enhance its stability, thereby improving the reliability of subsequent road construction procedures and the safety of construction workers.

[0003] Patent CN218713103U discloses a roadbed deep pit support device. This device, through the arrangement of an outer support plate, an inner support plate, a limiting cover, a rotating shaft, gears, a rack, and contact bolts, allows for rapid extension and expansion between the outer and inner support plates when encountering long pit walls, eliminating the need for additional wooden planks for fixing. It is convenient to use, and the inner support plate can be reversed for easy retrieval. The device is highly flexible and has a wide range of applications. However, while the overall design is easy to disassemble, store, and transport, it requires a certain amount of time for assembly and adjustment each time it is used, increasing the time required for use, raising time costs, and reducing work efficiency. Utility Model Content

[0004] (1) Technical problems solved

[0005] To address the shortcomings of existing technologies, this application provides a roadbed deep pit support device, which solves the problems mentioned in the background art.

[0006] (2) Technical solution

[0007] To achieve the above objectives, this application provides the following technical solution: a roadbed deep pit support device, comprising a fixed frame, a protective mechanism for preventing soil clods from falling, and a support mechanism for enhancing the stability of the protective mechanism. The top of the fixed frame is provided with a retraction mechanism that facilitates the quick storage or use of the support device. The retraction mechanism includes a chute and a sliding rod. The chute is opened inside the fixed frame, and both ends of the sliding rod are slidably connected to the chute. The bottom of the protective mechanism is fixedly connected to the top of the sliding rod, and the support mechanism is hinged to the right side of the protective mechanism.

[0008] By adopting the above technical solution, the protective mechanism can be easily folded and stored using the slide rail and slide bar, reducing the time required for disassembly and assembly and improving work efficiency.

[0009] Preferably, the retracting mechanism further includes a movable groove and a retaining hole. The movable groove is located on the top of the fixed frame and is connected to the sliding groove. The retaining hole is located at both ends of the sliding rod.

[0010] By adopting the above technical solution, the movable slot can provide a movable space for the extension and retraction of the protective mechanism, and the fixing hole can facilitate the fixing of the sliding rod.

[0011] Preferably, the retracting mechanism further includes a movable hole and a retaining rod. The movable hole is located on the left side of the slide groove, and the retaining rod is slidably connected to the movable hole. The surface of the retaining rod is in contact with the inner wall of the retaining hole.

[0012] By adopting the above technical solution, the sliding connection between the movable hole and the retaining rod can be used to insert the retaining rod into the retaining hole, thereby achieving the purpose of fixing the slide rod and enhancing the stability of the protective mechanism at the top of the slide rod.

[0013] Preferably, the retraction mechanism further includes a telescopic hole and a spring. The telescopic hole is opened at the bottom of the movable hole. The top of the spring is fixedly connected to the top of the telescopic hole. The spring is located outside the retaining rod. A control plate is fixedly connected to the bottom of the spring. The top side of the control plate is fixedly connected to the bottom of the retaining rod.

[0014] By adopting the above technical solution, the spring inside the telescopic hole can use its own elasticity to firmly fix the retaining rod on the top of the control board in the retaining hole, preventing external collisions from causing the retaining rod to disengage from the retaining hole of the slide rod and thus preventing the slide rod from moving.

[0015] Preferably, the protective mechanism includes an outer plate and an inner plate, the bottom of the outer plate is fixedly connected to the top of the slide rod, the top of the outer plate is provided with a lifting groove, and the surface of the inner plate is slidably connected to the lifting groove.

[0016] By adopting the above technical solution, the inner panel, which is slidably connected to the lifting groove of the outer panel, can be used to increase the protection range and facilitate the storage of the inner panel.

[0017] Preferably, the protective mechanism further includes an internally threaded tube and a lifting hole. The bottom of the internally threaded tube is fixedly connected to the bottom of the lifting groove. A first screw is threadedly connected to the inner wall of the internally threaded tube. A rotating plate is fixedly connected to the top of the first screw. The surface of the first screw is rotatably connected to the top of the inner plate. The lifting hole is opened at the bottom of the inner plate and is slidably connected to the surface of the internally threaded tube.

[0018] By adopting the above technical solution, the rotation of the rotating plate can drive the first screw of the internal threaded pipe connection to rotate. The rotation of the first screw drives the inner plate with lifting holes to move up and down, thereby adjusting the height of the protective mechanism to adapt to the depth of the pit.

[0019] Preferably, the support mechanism includes an outer tube and a second screw. The bottom of the outer tube is hinged to the right side of the movable groove, and a rotating tube is rotatably connected to one end of the outer tube. The surface of the second screw is threaded to the inner wall of the rotating tube, and one end of the second screw is hinged to the upper right side of the inner plate.

[0020] By adopting the above technical solution, the rotation of the outer tube can drive the extension and retraction of the second screw, providing support for the protective mechanism, enhancing its stability, and shortening the adjustment time.

[0021] Preferably, the support mechanism further includes a rubber ball and a circular hole. The bottom of the rubber ball is fixedly connected to the top of the second screw, and the circular hole is opened on the top left side of the fixing frame. The diameter of the circular hole is the same as that of the rubber ball.

[0022] By adopting the above technical solution, a rubber ball can be inserted into a circular hole to fix the position of the protective mechanism and the support mechanism located in the movable groove, thus avoiding damage caused by the movement of the protective mechanism and the support mechanism during transportation.

[0023] (3) Beneficial effects

[0024] This application provides a roadbed deep pit support device. It has the following beneficial effects:

[0025] 1. This roadbed deep pit support device, by setting up a retraction mechanism, allows the sliding rod in the chute to move to the left side of the movable groove. After releasing the control plate, the retaining rod, driven by the elastic force of the spring connected to the telescopic hole, passes through the retaining hole and the movable hole in sequence, fixing the position of the sliding rod. This reduces the time required for assembly when using the support device, lowers time costs, improves work efficiency, and further enhances the stability of the support device during use.

[0026] 2. This roadbed deep pit support device, by setting up a support mechanism, allows the rotating pipe connected to the outer pipe to adjust the exposed length of the second screw according to the height of the inner plate. When storing, the rubber ball is inserted into the circular hole, and the protective mechanism and support mechanism are stored in the movable groove, which reduces the space occupied by the support device during transportation, increases the convenience of transportation, and reduces the possibility of collision damage to the internal components of the support device during transportation.
