[0002] Slope support refers to a series of support, reinforcement and protection measures taken to ensure the stability and safety of the slope and its surrounding environment. In urban construction, the slope formed by the excavation of the building foundation pit often needs to be supported to control the deformation of the slope and prevent it from affecting the surrounding facilities because there are often other buildings or underground pipelines around it.

[0003] There is a common problem with existing slope support devices. As the foundation pit is continuously excavated, new support devices need to be added at a certain distance. When installing the new support devices, they will be affected by the upper support devices, making it difficult to install new support devices in a limited space. In addition, as the foundation pit is continuously excavated, every time workers enter and exit the foundation pit, it will become a new problem.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: an adjustable slope support device for a foundation pit of a construction project, comprising a guard plate mechanism 1, the guard plate mechanism 1 comprising a plurality of guard plates 11, the inner wall of each guard plate 11 is fixedly connected with a support block 12, the right side of each guard plate 11 is fixedly connected with a plug plate 13, the left side of each guard plate 11 is provided with a slot 14, and the interior of the guard plate 11 is provided with a support adjustment mechanism 2;

[0037] The support adjustment mechanism 2 includes a lifting unit 21, which is arranged inside the protective plate 11. The lifting unit 21 can adjust the height longitudinally inside the foundation pit.

[0038] As a further limitation of the support and adjustment mechanism 2 of the present invention, the lifting unit 21 includes a displacement base frame 2101, the displacement base frame 2101 is located inside the protective plate 11, the upper surface of the displacement base frame 2101 is fixedly connected to two limit frames 2102, the upper surface of the displacement base frame 2101 is fixedly connected to four limit rods 2103, the upper surface of each limit rod 2103 is fixedly connected to the bottom surface of the limit frame 2102, a displacement top frame 2104 is arranged above the displacement base frame 2101, the outer surface of each limit frame 2102 and the limit rod 2103 is slidably connected to the outer surface of the displacement top frame 2104, the bottom surface of the displacement top frame 2104 is fixedly connected to two hydraulic telescopic rods 2105, the telescopic end of each hydraulic telescopic rod 2105 passes through the displacement base frame 2101 and is fixedly connected to a storage box 2106, the upper surface of each storage box 2106 is fixedly connected to the bottom surface of the displacement base frame 2101, Eight limiting hydraulic rods 2107 are arranged above the base frame 2101, wherein the bottom surfaces of four limiting hydraulic rods 2107 are fixedly connected to the upper surface of the displacement base frame 2101, and the upper surfaces of the other four limiting hydraulic rods 2107 are fixedly connected to the bottom surface of the displacement top frame 2104. A plurality of first bolts 2108 are arranged on the outer side of each limiting hydraulic rod 2107, and the ends of each group of first bolts 2108 that are away from each other penetrate the limiting hydraulic rod 2107 and extend to the outside of the limiting hydraulic rod 2107. Two buffer springs 2109 are fixedly connected to the upper surface of the displacement base frame 2101. By providing a lifting unit 21, the eight supporting legs are divided into two groups, each of which is four in a group. By alternately supporting and contracting, the purpose of overall climbing and descending is achieved, so that the downward displacement can be achieved according to the depth of the foundation pit excavation, avoiding affecting the installation of the new support device, and solving the problem that the existing support device affects the installation of the new support device.

[0039] Two buffer pads 2110 are arranged below the displacement top frame 2104. The upper surface of each buffer pad 2110 is fixedly connected to the bottom surface of the displacement top frame 2104. The buffer pads 2110 are arranged to contact the buffer spring 2109, thereby reducing the friction between the upper surface of the buffer spring 2109 and the bottom surface of the displacement top frame 2104.

[0040] A hook 2111 is provided above each limit frame 2102, and two second bolts 2112 are provided above each hook 2111. The bottom end of each second bolt 2112 penetrates the hook 2111 and is threadedly connected to the inner wall of the limit frame 2102. The provided hook 2111 facilitates the lifting of the entire support device, and the hook 2111 can be firmly fixed by using the second bolts 2112.

[0041] The specific implementation of this embodiment is as follows: first, the displacement base frame 2101 and the displacement top frame 2104 are connected together by setting two hydraulic telescopic rods 2105. When the two hydraulic telescopic rods 2105 are extended and retracted at the same time, the distance between the displacement base frame 2101 and the displacement top frame 2104 can be controlled. At this time, the two buffer springs 2109 installed on the upper surface of the displacement base frame 2101 can have a buffering effect. When the displacement top frame 2104 is pressed down to contact with the upper surface of the buffer springs 2109, continuous downward pressure at this time will allow the two buffer springs 2109 to absorb the downward pressure to achieve the purpose of buffering. The lowest compressed height of the buffer spring 2109 will also exceed the height of the limiting hydraulic rod 2107, thereby avoiding the risk of the limiting hydraulic rod 2107 being collided. The storage box 2106 is set lower than the displacement base frame 2101, and Both hydraulic telescopic rods 2105 pass through the displacement base frame 2101 and are connected to the storage box 2106. Therefore, when the hydraulic telescopic rod 2105 is retracted to the shortest state, the hydraulic telescopic rod 2105 is stored in the storage box 2106. The cooperation of the limit frame 2102 and the limit rod 2103 can limit the displacement top frame 2104 to ensure the stability of the displacement top frame 2104 during movement. When it is necessary to descend, first use the four limit hydraulic rods 2107 installed on the displacement top frame 2104 to support it on both sides, and then use the two hydraulic telescopic rods 2105 to move the displacement base frame 2101 downward, and then use the four limit hydraulic rods 2107 on the displacement base frame 2101 to support it again. At this time, use the two hydraulic telescopic rods 2105 to retract the displacement top frame 2104, thereby completing the entire descent process.

[0042] Example 2: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: an adjustable slope support device for a foundation pit of a construction project. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The support adjustment mechanism 2 also includes a safety unit 22, which is arranged inside the protective plate 11. The safety unit 22 serves to ensure the overall safety of the support adjustment mechanism 2.

[0043] As a further limitation of the support adjustment mechanism 2 of the present invention, the insurance unit 22 includes eight support plates 2201, the outer surface of each support plate 2201 is fixedly connected to the telescopic end of the limiting hydraulic rod 2107, the outer surface of each support plate 2201 is fixedly connected to a scraper 2202, the inner wall of each scraper 2202 is rotatably connected to a rotating plate 2203, the upper surface of each rotating plate 2203 is fixedly connected to a stable seat 2206, the outer surface of each stable seat 2206 is fixedly connected to a pressure spring 2207, the upper surface of each scraper 2202 is fixedly connected to an L-shaped frame 2205, the end of each pressure spring 2207 away from the stable seat 2206 is fixedly connected to the outer surface of the L-shaped frame 2205, the inner wall of each scraper 2202 is fixedly connected to two baffles 2204, the upper surface of each group of baffles 2204 is in contact with the bottom surface of the rotating plate 2203, and the upper surface of each scraper 2202 is A fuse box 2208 is fixedly connected, and a rack 2209 is slidably connected to the inner wall of each fuse box 2208. A support frame 2210 is fixedly connected to the upper surface of each fuse box 2208. A servo motor 2211 is fixedly connected to the upper surface of each support frame 2210. The output end of the power of each servo motor 2211 passes through the fuse box 2208 and is fixedly connected to a driving gear 2212. The outer surface of each driving gear 2212 is meshed and connected with the outer surface of the rack 2209. The upper surface of each rack 2209 is fixedly connected to a limiting block 2213. The outer surface of each limiting block 2213 is slidably connected to the inner wall of the fuse box 2208. By providing a safety unit 22, the safety unit 22 is used to ensure the safety of the support adjustment mechanism 2 when it is descending or ascending. In the event of an accident in the hydraulic equipment or the electronic equipment, the support adjustment mechanism 2 can be supported as a whole to avoid causing greater losses.

[0044] The outer surface of each support plate 2201 is fixedly connected with two anti-wear pads 2214, and the interior of each support plate 2201 is provided with four third bolts 2215. The anti-wear pads 2214 are provided to prevent the support plate 2201 from directly rubbing against the protective plate 11, thereby preventing the support plate 2201 from being damaged. When the support plate 2201 needs to be fixed for a long time, the third bolts 2215 can be used to connect the support plate 2201 and the protective plate 11 together;

[0045] The outer surface of each support plate 2201 is fixedly connected with four triangle irons 2216, and the side of each group of triangle irons 2216 close to each other is fixedly connected to the outer surface of the scraper 2202. The four triangle irons 2216 are provided to increase the stability of the fixed relationship between the support plate 2201 and the scraper 2202;

[0046] Two fourth bolts 2217 are arranged above each stabilizing seat 2206, and the bottom end of each fourth bolt 2217 passes through the stabilizing seat 2206 and is threadedly connected to the inner wall of the scraper 2202. The stabilizing seat 2206 is installed on the upper surface of the scraper 2202 by the arranged fourth bolts 2217, thereby achieving the purpose of fixing the stabilizing seat 2206.

[0047] The specific implementation of this embodiment is as follows: first, the servo motor 2211 is electrically connected through a wire. When the power provided by the limit hydraulic rod 2107 drives the support plate 2201 to move, the scraper 2202 can be pushed into the inside of the protective plate 11, and then the scraper 2202 is used to fit and contact the protective plate 11, thereby achieving the effect of supporting the protective plate 11. If the scraper 2202 moves downward at this time, the scraper 2202 can be used to scrape off the dirt on the inner wall of the protective plate 11, so as to achieve the purpose of cleaning the dirt on the surface of the protective plate 11. At this time, the baffle 2204 is used to rotate the rotating plate 220 3 is blocked to ensure that the rotating plate 2203 cannot go over the baffle 2204 and rotate downward. The baffle 2204 can only allow the rotating plate 2203 to rotate upward. If the scraper 2202 moves downward, a support block 12 appears below, and the rotating plate 2203 can be rotated upward. At this time, the pressure spring 2207 can absorb the extrusion force of the rotating plate 2203 rotating upward, and the L-shaped frame 2205 and the stable seat 2206 can be used to stably limit the pressure spring 2207. If it passes over the support block 12 at this time, the pressure spring 2207 can be used to The stabilizing seat 2206 rebounds back, and then the stabilizing seat 2206 drives the rotating plate 2203 to rebound to the upper surface of the baffle 2204. If the overall position of the support adjustment mechanism 2 has been determined at this time, the power provided by the servo motor 2211 can be used to drive the driving gear 2212 to rotate, and the driving gear 2212 is engaged with the rack 2209 to achieve the effect of driving the rack 2209 to move. At this time, the relationship between the fixed connection between the limit block 2213 and the rack 2209 is used, and the limit block 2213 is limited by the fuse box 2208 to ensure that It is not easy to move all the rack 2209 out, so the problem of frequent maintenance of the rack 2209 is avoided. At this time, the extended rack 2209 is located above the rotating plate 2203, so the rotating plate 2203 cannot rotate. If the hydraulic equipment or electronic equipment fails, the support and adjustment mechanism 2 as a whole may naturally drop due to lack of power. After dropping to the position of the support block 12, the rotating plate 2203 loses its active space, so as to achieve the effect of supporting the rotating plate 2203 and the support and adjustment mechanism 2 as a whole, and avoid greater losses.

[0048] Example 3: Please refer to Figure 1-Figure 11The present invention provides a technical solution: an adjustable slope support device for a foundation pit of a construction project. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A convenient ladder mechanism 3 is arranged inside the protective plate 11. The convenient ladder mechanism 3 is located outside the lifting unit 21. The convenient ladder mechanism 3 is used in conjunction with the support adjustment mechanism 2. The convenient ladder mechanism 3 facilitates workers to enter and exit the foundation pit.

[0049] As a further limitation of the convenient ladder mechanism 3 of the present invention, the convenient ladder mechanism 3 includes two limit frames 301, the backs of the two limit frames 301 are in contact with the front of the limit frame 2102, the inner wall of each limit frame 301 is slidably connected with a positioning block 302, the inner wall of each positioning block 302 is fixedly connected with two compression springs 303, each compression spring 303 is fixedly connected with a steel ball 304 at one end away from the positioning block 302, each steel ball 304 is located inside the positioning block 302, the bottom surface of each positioning block 302 is fixedly connected with an extension rod 305, the front sides of the two extension rods 305 are jointly fixedly connected with six first ladder rods 306, and the front of each limit frame 301 The outer surface of each first ladder rod 306 is provided with a slide groove 310, and the outer surface of each first ladder rod 306 slides inside the slide groove 310. The outer surface of each limit frame 301 is provided with four positioning holes 308. The outer surface of each steel ball 304 contacts the inner wall of the positioning hole 308. Five second ladder rods 307 are fixedly connected to the front of one limit frame 2102, and the outer surface of each extension rod 305 is fixedly connected to a foot pad 309. By providing a convenient ladder mechanism 3, the convenient ladder mechanism 3 is installed on the support adjustment mechanism 2 to solve the problem of inconvenience of workers entering and exiting the foundation pit every time, thereby saving the cost of building another staircase, facilitating workers to enter and exit the foundation pit, and effectively improving the progress of construction;

[0050] Two mounting plates 311 are provided on the outside of each limit frame 301, and the outer surface of each mounting plate 311 is in contact with the outer surface of the limit frame 2102. Two fifth bolts 312 are provided on the outside of each mounting plate 311, and one end of each fifth bolt 312 close to the mounting plate 311 penetrates the mounting plate 311 and extends to the outside of the mounting plate 311. By utilizing the cooperation between the mounting plate 311 and the fifth bolt 312, the purpose of stably mounting the limit frame 301 on the outer surface of the limit frame 2102 can be achieved.

[0051] The specific implementation method of this embodiment is: first, the worker grabs the extension rod 305 with his hand or a tool and pulls it downward. At this time, the extension rod 305 drives the positioning block 302 to apply a pulling force downward. At this time, the steel ball 304 inside the positioning block 302 is subjected to the downward pulling force and will be retracted into the interior of the positioning block 302. Specifically, the relationship between the fixed connection between the steel ball 304 and the compression spring 303 and the fixed connection between the compression spring 303 and the inner wall of the positioning block 302 are utilized, and the positioning hole 308 is smaller than the steel ball 304. Therefore, the steel ball 304 will never pass through the positioning hole 308. When the downward force is generated, the steel ball 304 is forced to be squeezed into the interior of the positioning block 302 due to the influence of its own smooth surface. At this time, the steel ball 304 breaks away from the positioning hole 308 and fits with the inner wall of the limit frame 301. , because it is forced to squeeze back into the interior of the positioning block 302, the rebound force accumulated by the compression spring 303 will be greater at this time, until the positioning block 302 is pulled to the bottom of the limit frame 301, at this time, the positioning hole 308 appears again at the bottom of the limit frame 301, and the steel ball 304 will be quickly entered into the interior of the positioning hole 308 by the rebound force of the compression spring 303, thereby achieving the purpose of clamping the positioning block 302 and the extension rod 305, and the extension rod 305 is also put down at this time, and the first ladder rod 306 and the second ladder rod 307 can be used to easily climb to the top of the support adjustment mechanism 2, and then come up from the bottom of the foundation pit, and then use external tools to build an aisle to walk from the support adjustment mechanism 2 to the ground, compared with the traditional way of building stairs, it has the advantages of saving materials and time.
