[0003] However, the device has certain shortcomings in use. It is not easy to adjust and control, and it is not suitable for supporting the bottom of slopes with different gradients. In addition, the device has a small contact area with the ground when installed on the ground, resulting in insufficient stability. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary support device for slope construction in water conservancy projects, which solves the problems of the device being inconvenient to adjust and control, providing support for the bottom of slopes with different slopes, and having a small contact area with the ground and insufficient stability when the device is installed on the ground.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temporary support device for slope construction in water conservancy projects, comprising a base plate, a bidirectional screw rod, and two guide rods. A top plate is hinged to the upper end of the base plate. Two symmetrically distributed screw cylinders are threadedly connected to the outer side of the bidirectional screw rod. One screw cylinder is hinged to the base plate, and the other screw cylinder is hinged to the top plate. A plug cylinder is installed inside the base plate through a bearing. A fixing mechanism is provided on the plug cylinder. A slip ring is slidably connected to the outer side of the plug cylinder. A guide block is fixedly connected inside the slip ring. The guide block and the plug cylinder are slidably connected.

[0006] Preferably, each guide rod has two symmetrically distributed guide cylinders slidably connected to its outer side, one of which is hinged to the bottom plate and the other to the top plate. This arrangement of guide cylinders and guide rods enhances the stability of the top plate support.

[0007] Preferably, a handle is fixedly connected to the surface of the slip ring, and the handle is slidably connected to the base plate. The handle limits the movement of the slip ring.

[0008] Preferably, the fixing mechanism includes a support ring, which is fixedly connected inside the insert cylinder. A wedge block is slidably connected to the upper end of the support ring, and an insert plate is fixedly connected to the surface of the wedge block. The insert plate and the insert cylinder are slidably connected. A lead screw is mounted inside the insert cylinder via a bearing, and a threaded tube is threaded to the outer side of the lead screw. The threaded tube and the support ring are slidably connected. A pressure ring is slidably connected inside the insert cylinder, and the pressure ring and the wedge block are slidably connected. A spring is installed inside the insert cylinder. By rotating the insert cylinder into the ground, and by rotating the lead screw and the threaded tube, the conical ring moves and presses against the wedge block, causing the insert plate to extend from the insert cylinder, increasing the contact area of ​​the device on the ground, and thus making the device more stable when installed on the ground.

[0009] Preferably, a guide pin is fixedly connected to the surface of the solenoid, and the guide pin is slidably connected to the insert. The guide pin guides the movement of the solenoid.

[0010] Preferably, a conical ring is fixedly connected to the outer side of the solenoid, and the conical ring and the inclined block are slidably connected. The movement of the inclined block is controlled by the conical ring.

[0011] Preferably, one end of the spring is fixedly connected to the support ring, and the other end of the spring is fixedly connected to the pressure ring. By providing the spring, the pressure ring can be easily reset.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a rotating insert cylinder to enter the ground, and the rotating screw and solenoid make a threaded movement, which causes the conical ring to move and squeeze the inclined block, thereby causing the insert plate to extend out of the insert cylinder, increasing the contact area of ​​the device on the ground, and thus making the device more stable when installed on the ground.

[0014] 2. This utility model uses the rotation of a bidirectional screw and a screw barrel to make a threaded motion, thereby changing the distance between the two screw barrels, which in turn changes the angle between the bottom plate and the top plate. This allows the device to support slopes with different angles, making the device more versatile. Attached Figure Description
