Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically a high-excavation slope protection device. Background Technology

[0002] High-excavation foundation pits mainly exist when the roadbed passes through a soil slope. They are mainly roadbed sections where the design elevation is lower than the original ground elevation. During construction, the top of the soil slope is leveled, and then a foundation pit is excavated at the leveled part. Since the soil on the slope is rich in a lot of water, in addition to opening a water storage pit on the side of the foundation pit to collect the water in the soil slope, safety support devices must also be added to the slope of the foundation pit.

[0003] Chinese utility model patent, authorization announcement number CN219527676U, discloses a safety support device for excavated foundation pits. It features a threaded cylinder with opposite threads at both ends. By turning the cylinder, the two screws move in opposite directions, thereby opening the two support rods on the screws and creating compression support for the sidewalls of the foundation pit to prevent collapse. This utility model has a simple structure, is easy to operate, and saves time and effort in assembly and disassembly.

[0004] The above solution solves the technical problems mentioned in the background art. However, in practical applications, the above solution still has certain defects. For example, when installing the above device, it is necessary to insert the upper support rod into the insert cylinder and then insert the lower support rod into the transverse groove. The installation process is cumbersome, which reduces the installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a high-excavation slope support device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-excavation slope support device, comprising two support plates parallel to the foundation pit slope, wherein a base and a top seat are respectively provided at the bottom and top of the two support plates, and a vertical block is fixed at the top of the base;

[0007] The top of the vertical block is fixed with a bottom hinge seat, each support plate is fixed with a side hinge seat on its side, and the bottom of the top seat is fixed with a top hinge seat.

[0008] A bottom hinge plate and a top hinge plate are movably connected between the side hinge seat on one side and the bottom hinge seat and the top hinge seat, respectively.

[0009] A driving component is installed between the vertical block and the top seat, which drives the two support plates to move towards each other or away from each other.

[0010] Preferably, the bottom end of the base is provided with several sets of horizontally distributed rollers.

[0011] Preferably, the driving component includes a rotating shaft and a lead screw, with the central axes of the rotating shaft and the lead screw coinciding;

[0012] The rotating shaft is movably connected to the vertical block, and the lead screw is movably screwed to the top hinge seat.

[0013] Preferably, both the shaft and the lead screw are fixed to a fixed plate at their ends. Several screws are fixed on the plate body of one of the fixed plates. The screws are movably connected to the other fixed plate, and a fastening nut is screwed onto the body of the screw.

[0014] Preferably, a handwheel is fixed on the shaft of the rotating shaft.

[0015] Preferably, a pull ring is fixed to the top of the top seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This high-excavation slope protection device is equipped with two support plates, two sets of bottom hinge plates, and a top hinge plate. During installation, turning the handwheel causes the screw to rotate, which in turn moves the top seat downward. At this time, the two support plates move in opposite directions until they are pressed against the two sides of the pit, thus completing the slope protection. Since the two sets of bottom hinge plates and the top hinge plate of this device are movably connected together, they do not need to be installed separately, reducing manpower consumption and improving installation efficiency.

[0018] Meanwhile, a lead screw and a rotating shaft are provided. When the two fixed plates separate, the top seat is pulled upward, the top seat moves upward, and the two support plates move towards each other, which reduces the volume of the support device, makes it easier to store the support device, and thus facilitates its transportation, improving the practicality of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The support device in this plan is used to protect the slopes on both sides of the excavated earthwork foundation pit.

[0025] like Figures 1-2 As shown, this utility model provides a technical solution: a high-excavation slope support device, including two support plates 5 parallel to the foundation pit slope, a base 1 and a U-shaped top seat 4 respectively provided at the bottom and top of the two support plates 5, a vertical block 2 fixed at the top of the base 1, a bottom hinge seat 3 fixed at the top of the vertical block 2, a side hinge seat 6 fixed at the middle of the side of each support plate 5, and a top hinge seat fixed at the bottom of the top seat 4, with connecting shafts movably connected to both sides of all the hinge seats.

[0026] A bottom hinge plate 7 and a top hinge plate 8 are movably connected between the side hinge seat 6 on one side, the bottom hinge seat 3, and the top hinge seat, respectively. That is, the two sides of the bottom hinge plate 7 are movably connected to the connecting shafts of the side hinge seat 6 and the bottom hinge seat 3, respectively, and the two sides of the top hinge plate 8 are movably connected to the connecting shafts of the top hinge seat and the side hinge seat 6, respectively. The two bottom hinge plates 7 and the two top hinge plates 8 form a quadrilateral structure.

[0027] A driving component is provided between the vertical block 2 and the top seat 4. The driving component drives the two support plates 5 to move in opposite directions or in opposite directions. When the two support plates 5 move in opposite directions, the slope of the foundation pit is supported. When the two support plates 5 move in opposite directions, the slope of the foundation pit is unsupported.

[0028] A pull ring 9 is fixed to the top of the top seat 4. In use, the crane hook engages the pull ring 9 to lift the entire device, then the support device is moved to the required support position and slowly lowered. The placement of the support device is as follows: Figure 1 As shown.

[0029] Since the support device may not be placed in the middle between the two slopes, several sets of horizontally distributed rollers 101 are provided at the bottom of the base 1 for convenient support. In this way, after the support plate 5 on one side is squeezed against the slope of the pit, the support device is subjected to a reverse thrust, which drives the base 1 to move in the opposite direction through the rollers 101 until the two support plates 5 are squeezed against the slopes on both sides of the pit respectively.

[0030] like Figure 2As shown, the driving component includes a rotating shaft 10 and a lead screw 12. The central axes of the rotating shaft 10 and the lead screw 12 coincide. The rotating shaft 10 is movably connected to the vertical block 2, and the lead screw 12 is movably screwed to the top hinge seat. To facilitate the rotation of the rotating shaft 10, a handwheel 11 is fixed on the shaft of the rotating shaft 10.

[0031] To reduce the size of the support device and facilitate its storage and transportation, the rotating shaft 10 and the lead screw 12 are separately configured in this design. A fixing plate 13 is fixed to the end of both the rotating shaft 10 and the lead screw 12. Several screws 14 are fixed to the body of one of the fixing plates 13. The screws 14 are movably inserted into the other fixing plate 13. After installation, to achieve a fixed connection between the two fixing plates 13, a fastening nut is screwed onto the body of the screw 14. Figure 3 As shown, when the two fixed plates 13 are separated, the top seat 4 is pulled upwards, the top seat 4 moves upwards, and the two support plates 5 move towards each other, thereby realizing the storage of the support device.

[0032] As a supplement to this scheme, during installation, the support device is placed in the foundation pit using a crane, keeping the support plates 5 on both sides parallel to the slope of the foundation pit. After the crane lowers the support device, the top seat 4 moves downward under gravity, and the screw 14 is inserted into the through hole of the bottom fixing plate 13. The two fixing plates 13 are fixed by tightening nuts. At this time, the handwheel 11 is turned, and the screw 12 rotates, driving the top seat 4 to move downward. At this time, the two support plates 5 move in opposite directions until the two support plates 5 are pressed against the two slopes of the foundation pit respectively, thus completing the slope support.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
