[0020] The present invention provides a water conservancy project construction device, as shown below Figures 1 to 6 The present invention is described with reference to the structural schematic diagram of FIG.

[0021] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] When engineers are working in the foundation pit, the pit walls on both sides of the foundation pit are prone to collapse, making it difficult to ensure the safety of the construction workers. In order to prevent the collapse of the pit wall from causing harm to the construction workers, protective plates are generally set on both sides of the foundation pit to support the pit walls of the foundation pit to prevent the pit walls from collapsing during construction. However, the protective plates are connected to the pit walls through connectors, and the structure of the pit walls is unstable, so that the support effect provided by the protective plates is poor. When the depth of the foundation pit is deeper, the top of the protective plate will be squeezed by the pit wall more and more, and the top of the protective plate will break and collapse.

[0023] At present, in order to ensure the safety of construction workers in the foundation pit, most of them build a support frame between the two protective plates, and use the support frame to provide stable support for the two protective plates, so as to avoid the failure of the protective plates when the foundation pit is deep. However, when the prefabricated cement slabs need to be hoisted into the foundation pit, the support frame between the two protective plates will hinder the hoisting and laying of the cement slabs. In order to smoothly install the prefabricated cement slabs in the foundation pit, the support frame needs to be removed first, and then rebuilt after the hoisting and installation construction is completed, which makes the construction of prefabricated cement slabs in the foundation pit inconvenient.

[0024] Based on the above problems, an embodiment of the present invention provides a water conservancy project construction device, which can pull and support the pit wall from the top of the foundation pit through the use of a mounting seat in conjunction with the support rod, protective parts and driving mechanism of the protective assembly, so as to avoid collapse of the top of the pit wall when the foundation pit is deep, thereby ensuring the safety of water conservancy construction personnel in the foundation pit. At the same time, the driving mechanism drives the protective parts to move, so that the protective parts can quickly abut or separate from the pit wall of the foundation pit, thereby realizing rapid installation and disassembly of the protective device. After the protective parts are separated from the pit wall when lifting the cement slab, the protective device can be moved away from the position to avoid affecting the lifting of the cement slab, thereby improving the convenience of laying cement slabs in the foundation pit. The water conservancy project construction device of the present invention is easy to use, has good protective effect, is highly practical, and is worthy of promotion.

[0025] Reference Figure 1 , Figure 1 FIG. 1 is a top view of the construction device of this embodiment, as shown in FIG. Figure 1 As shown, a water conservancy project construction device includes two mounting seats 1 respectively placed on the ground on both sides of the foundation pit mouth, a protection component is arranged between the two mounting seats 1, and the protection component includes a plurality of support rods 2 horizontally arranged between the two mounting seats 1, both ends of the support rods 2 are connected to the mounting seats 1, two protection members 3 are vertically arranged between the two mounting seats 1, the protection members 3 and the support rods 2 are perpendicular to each other, the support rods 2 pass through the protection members 3 and are slidably connected thereto, a driving mechanism is arranged on the mounting seats 1, and the output end of the driving mechanism is connected to the protection members 3, for driving the protection members 3 to move along the support rods 2, so that the sides of the two protection members 3 away from each other are respectively abutted against or separated from the pit wall of the foundation pit.

[0026] When the device utilizes the protective member 3 to provide protective support for the foundation pit, the pit wall is pulled and supported from the top of the foundation pit. The structure at the bottom of the foundation pit is relatively stable due to the gravity and other effects on the upper part, so that the supporting effect of the protective member 3 is at the position where the foundation pit is most likely to collapse, further improving the protective effect. The movable protective member 3 and protective device can realize the rapid installation and disassembly of the protective device, which is convenient for movement when lifting cement slabs, thereby improving the convenience of water conservancy construction.

[0027] Reference Figure 6 , Figure 6 FIG. 1 is a top view of the foundation pit protection by the construction device of this embodiment, as shown in FIG. Figure 6 As shown, when the protective member 3 of the device abuts against or separates from the pit wall of the foundation pit, it is necessary to avoid the protective member 3 abutting against or separating from the pit wall at a fast speed, otherwise the rock and other structures on the pit wall will be affected by vibration, reducing the overall stability of the pit wall and causing collapse.

[0028] To this end, the present embodiment provides a solution as a further optimization scheme. In the present embodiment, the driving mechanism includes a first rotating power unit 21, a thread is provided on the support rod 2, the protective member 3 is threadedly connected to the support rod 2, both ends of the support rod 2 are rotatably connected to the mounting seat 1, the first rotating power unit 21 is fixed on the mounting seat 1, and the output end of the first rotating power unit 21 is connected to the support rod 2 for driving the support rod 2 to rotate.

[0029] In this embodiment, the thread on the support rod 2 is used in conjunction with the first rotating power unit 21, so that the support rod 2 rotates to drive the protective member 3 to move slowly, and then the protective member 3 slowly abuts against the pit wall or separates from the pit wall, thereby preventing the structure on the pit wall from being significantly affected by impact, vibration, etc., and further improving the protection effect on water conservancy construction.

[0030] It should be understood that the first rotating power unit 21 in this embodiment should be a component that can provide rotational motion, including but not limited to a conventional motor and a matching reducer or servo, which can drive the protective member 3 to move by rotating the support rod 2.

[0031] When the device is used to protect and support the pit wall of the foundation pit, the supporting force is actually provided by the friction between the mounting base and the ground on both sides of the foundation pit, and the mounting base needs to be fixed.

[0032] To this end, the present embodiment improves the mounting seat, referring to Figure 2 , Figure 2 It is a front view of the construction device of this embodiment, as shown in Figure 2As shown, as a further optimization scheme, the present embodiment also includes a bracket, which is vertically arranged on the ground on both sides of the foundation pit mouth, and the mounting seat 1 is fixed on the bracket. A plurality of anchors 4 are vertically arranged at equal intervals on the bracket, and the anchors 4 are located directly below the mounting seat 1. The anchors 4 are slidably connected to the bracket along the vertical direction. A transmission mechanism is provided on the mounting seat 1, and the input end of the transmission mechanism is connected to the support rod 2, and the output end thereof is connected to the anchor 4. The anchor 4 is driven to move by the support rod 2 so that the anchor 4 is inserted into the ground or removed from the ground. The anchor 4 in this example is an anchor rod or an anchor nail.

[0033] In this embodiment, multiple anchors 4 enable the bracket and the mounting base 1 to be anchored on the ground, which can provide a stable pulling force for the protective member 3, further improving the protective effect on water conservancy construction. At the same time, a transmission mechanism is used to enable the protective member to abut and separate from the pit wall and to be inserted into and detached from the ground simultaneously with the anchor 4, which greatly improves the speed of installation and disassembly of the protective device and further improves its ease of use.

[0034] Reference Figure 3 , Figure 3 AA is a cross-sectional view of the construction device of this embodiment, as shown in Figure 3 As shown, as a further optimization scheme, the transmission mechanism in this embodiment includes a first screw 41, a worm gear mechanism and a connecting plate 42. The first screw 41 is vertically arranged on the bracket and is rotatably connected thereto. One end of the first screw 41 extends into the mounting seat 1 and is rotatably connected to the support rod 2 through the worm gear mechanism. A connecting plate 42 is horizontally provided on the top of the multiple anchors 4. The connecting plate 42 is fixedly connected to the anchors 4. The first screw 41 passes through the connecting plate 42 and is threadedly connected thereto.

[0035] This embodiment utilizes the first screw 41 of the transmission mechanism, the worm gear mechanism and the connecting plate 42, so that when the support rod 2 rotates to drive the protective member to move, the first screw 41 is simultaneously driven to rotate, so that the connecting plate 42 drives multiple anchors to be installed and disassembled.

[0036] As a further optimization scheme, the bracket in this embodiment includes a base 11 and two support plates 12, the two support plates 12 are vertically arranged on the top of the base 11, the central axis of the support plate 12 and the support rod 2 are parallel to each other, the connecting plate 42 is located directly above the base 11, and a plurality of through holes 13 are vertically opened on the base 11 at equal intervals, the anchor 4 passes through the through holes 13 and is slidably connected thereto, the mounting seat 1 is located directly above the connecting plate 42, the mounting seat 1 is connected to the support plate 12, and the end of the first screw 41 away from the mounting seat 1 is rotatably connected to the base 11.

[0037] Since the depth of the foundation pit gradually increases with continuous excavation, the pit wall needs to be protected during the excavation process, otherwise the pit wall collapses during the excavation process, affecting the excavation efficiency.

[0038] To this end, the present embodiment improves the bracket as a further optimization scheme. In the present embodiment, a slide groove 121 is vertically opened on one side where the two support plates 12 are close to each other. The end of the mounting seat 1 extends into the slide groove 121 and is slidably connected thereto. A linear displacement mechanism is provided on the base 11. The output end of the linear displacement mechanism is connected to the mounting seat 1 for driving the mounting seat 1 to move along the slide groove 121.

[0039] This embodiment uses the slide groove 121 on the support plate 12 in conjunction with the linear displacement mechanism to facilitate adjustment of the height of the mounting seat 1, so that it can be used for protection during foundation pit excavation, so that the protective component moves downward with the foundation pit, further improving the protective effect.

[0040] Reference Figure 4 , Figure 4 BB is a cross-sectional view of the construction device of this embodiment, as shown in Figure 4 As shown, as a further optimization scheme, the linear displacement mechanism in this embodiment includes a second screw 122 and a second rotating power unit 123.

The second rotating power unit 123 is fixed on the support plate 12, and the output shaft of the second rotating power unit 123 is fixedly connected to the second screw 122 for driving the second screw 122 to rotate.

[0041] It should be understood that the second rotating power unit 123 in this embodiment should be a component that can provide rotational motion, including but not limited to a conventional motor and a matching reducer or servo, and the second screw 122 can drive the mounting base 1 to move along the slide groove by rotating.

[0042] Reference Figure 5 , Figure 5 This is an enlarged schematic diagram of the construction device at C in this embodiment, as shown Figure 5 As shown, as a further optimization scheme, in this embodiment, the interior of the mounting base 1 is hollow, and a multi-stage telescopic rod 412 is vertically arranged inside the mounting base 1. The outermost rod body of the multi-stage telescopic rod 412 is rotatably connected to the mounting base 1, and the outermost rod body of the multi-stage telescopic rod 412 is rotatably connected to the support rod 2 through a worm gear mechanism, and the end of the innermost rod body of the multi-stage telescopic rod 412 close to the connecting plate 42 is fixedly connected to the first screw 41.

[0043] The multi-stage telescopic rod 412 in this embodiment is composed of multiple hollow rod bodies. A sliding groove is provided on the inner wall of the upper rod body, and a slider is provided on the lower rod body, so that when the mounting seat 1 moves up and down, the support rod 2 can still synchronously drive the first screw to rotate.
