Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a slope support frame for water conservancy canal excavation construction. Background Technology

[0002] Water conservancy canal excavation involves excavating slopes around canals with significant topographic relief, either to create access roads or construction sites, thus artificially creating a steep slope around the canal. Slope protection is carried out to ensure slope stability and the safety of excavation workers.

[0003] Existing support structures for slopes in water conservancy ditch excavation are usually supported by steel structures. This requires workers to spend a long time on construction and preparation. After the bridge piers and abutments are constructed, the steel structures also need to be dismantled, which is troublesome. There are safety risks in both the construction and dismantling of the support structures. Moreover, the existing steel structures used as slope support structures for excavation platforms only provide surface support and have poor support effect, which is not conducive to the stability of slope construction.

[0004] Therefore, it is essential to provide a slope support frame for water conservancy canal excavation construction to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a slope support frame for water conservancy canal excavation construction. The support angle is adjusted by the cooperation of the rotating shaft and the movable plate on the bottom support platform. The auxiliary support plates installed on both sides of the bottom support platform can increase the contact area with the ground and prevent soil slippage during the support process. After the bottom support platform is fixed by positioning pins, the movable plate can be supported by the support structure. The movable plate can be angled by the hydraulic cylinder in the support structure. The fixing pins set on the movable plate can also improve the fastening support efficiency by pouring external cement grout, thereby improving the stability of the slope during water conservancy canal excavation construction.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] A slope support frame for water conservancy canal excavation construction is provided, including a bottom support platform, positioning holes are provided at the four corners of the bottom support platform, positioning pins are installed inside the positioning holes, a rotating shaft platform is installed at one end of the bottom support platform, a movable plate is connected to the rotating shaft platform, a support structure is provided between the bottom support platform and the movable plate, and auxiliary support plates are installed on both sides of the bottom support platform respectively.

[0008] The support structure includes a fixed block, which is fixed in the center of the bottom support platform. A trapezoidal block is integrally formed on the top of the fixed block. A hydraulic cylinder is installed on the trapezoidal block. A universal joint is set on the top of the hydraulic cylinder. An abutment block is installed on the universal joint and fixed to the movable plate.

[0009] Specifically, the movable board includes a board body with a bending section in the center, which divides the board body into upper and lower parts. A fixing mechanism is installed on the upper part of the board body, and an abutment block is fixedly installed on the lower part of the board body.

[0010] Specifically, the fixing mechanism includes four sets of circular grooves, which are rectangularly formed on the plate, and fixing pins are installed through the inside of the circular grooves.

[0011] Specifically, the fixed drill includes a drill body with a cavity inside, a drill bit at the bottom of the drill body, a pouring hole between the drill bit and the cavity, and a pouring port at the end of the drill body that communicates with the cavity.

[0012] Specifically, the auxiliary support plate includes a triangular cover plate, on which a rotating shaft roller is installed. The rotating shaft roller is installed on both sides of the bottom support platform and can rotate from 0° to 90°.

[0013] This utility model adjusts the support angle by cooperating with the rotating shaft and movable plate on the bottom support platform. The auxiliary support plates installed on both sides of the bottom support platform can increase the contact area with the ground and prevent soil slippage during the support process. After the bottom support platform is fixed by positioning pins, the movable plate can be supported by the support structure.

[0042] The present invention will be further described in conjunction with the following embodiments.

[0043] Example 1.

[0044] like Figure 1-2 As shown, a slope support frame for water conservancy canal excavation includes a bottom support platform 1, with positioning holes 2 at the four corners of the bottom support platform 1, and positioning pins 3 installed inside the positioning holes 2. A rotating shaft platform 4 is installed at one end of the bottom support platform 1, and a movable plate 5 is connected to the rotating shaft platform 4. A support structure 6 is provided between the bottom support platform 1 and the movable plate 5, and auxiliary support plates 7 are installed on both sides of the bottom support platform 1.

[0045] The bottom support platform 1 can be fixed by the positioning pins installed in the four corner positioning holes 2. After being fixed by the four sets of positioning pins, it works with the auxiliary support plate 7 to increase the contact area with the ground and increase stability. The steel structure installed on the bottom support platform 1 can adjust the angle of the movable plate 5 installed on the rotating shaft platform 4, which is convenient for supporting different slopes.

[0046] The support structure 6 includes a fixing block 8, which is fixed in the center of the bottom support platform 1. A trapezoidal block 9 is integrally formed on the top of the fixing block 8. A hydraulic cylinder 10 is installed on the trapezoidal block 9. A universal joint 11 is provided on the top of the hydraulic cylinder 10. An abutment block 12 is installed on the universal joint 11 and is fixed on the movable plate 5.

[0047] The cooperation between the fixed block 8 and the trapezoidal block 9 enhances the stability of the support structure 6 and provides bottom support for the hydraulic cylinder 10. The universal joint 11 installed at the top end of the hydraulic rod can rotate inside the abutment block 12. In conjunction with the lifting adjustment of the hydraulic cylinder 10, the angle between the movable plate 5 and the bottom support platform 1 is adjusted, which facilitates the movable plate 5 to support slopes at various angles.

[0048] The movable board 5 includes a board body 16, with a bending part 13 in the center of the board body 16. The bending part 13 divides the board body 16 into upper and lower parts. A fixing mechanism 14 is installed on the upper part of the board body 16, and an abutment block 12 is fixedly installed on the lower part of the board body 16.

[0049] The fixing mechanism 14 installed on the upper part of the plate 16 can not only support the slope but also increase the fixing effect. The bending part 13 can be easily matched with various slopes.

[0050] The fixing mechanism 14 includes four sets of circular grooves 15. The four sets of circular grooves 15 are rectangularly formed on the plate 16. A fixing pin 17 is installed through the circular grooves 15. The fixing pin 17 limits the plate 16 through the four sets of circular grooves 15 and fixes the plate 16 on the slope.

[0051] The fixing rod 17 includes a rod body 18, with a cavity 20 inside the rod body 18. A drill bit 19 is provided at the bottom of the rod body 18, and a pouring hole 21 is provided between the drill bit 19 and the cavity 20. A pouring port 22 is opened at the end of the rod body 18, which is connected to the cavity 20. The rod body 18 can be filled with external cement slurry into the cavity 20 through the pouring port 22. After the rod body 18 is driven into the slope by the drill bit 19, the cement in the cavity 20 can flow out through the pouring hole 21, which improves the overall stability of the fixing rod 17 and increases the fixing effect of the movable plate 5.

[0052] The auxiliary support plate 7 includes a triangular cover plate 23, on which a rotating shaft roller 24 is installed. The rotating shaft roller 24 is installed on both sides of the bottom support platform 1. The rotating shaft roller 24 can rotate from 0° to 90°. The triangular cover plate 23 can cooperate with the bottom support platform 1 to increase the contact area with the ground and improve stability. At the same time, through the operation and rotation of the rotating shaft roller 24, the triangular cover plate 23 can protect the bottom sides of the bottom support platform 1 to prevent external soil from entering and affecting the support efficiency during the hydraulic construction process.

[0053] During the production process, the support angle is adjusted by the cooperation of the rotating shaft platform 4 and the movable plate 5 on the bottom support platform 1. The auxiliary support plates 7 installed on both sides of the bottom support platform 1 can increase the contact area with the ground and prevent soil slippage during the support process. After the bottom support platform 1 is fixed by the positioning pins 3, the movable plate 5 can be supported by the support structure 6. The movable plate 5 is angled by the hydraulic cylinder 10 in the support structure 6. The fixing pins 17 set on the movable plate 5 can also improve the fastening support efficiency by pouring external cement slurry, thereby improving the stability of the slope during water conservancy canal construction.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
