Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a foundation pit support device. Background Art

[0002] A foundation pit support device is a device used to ensure the stability of a foundation pit, mainly applied in underground engineering construction to prevent the collapse of surrounding soil and rocks.

[0003] The structure of the existing foundation pit support device is a foundation pit support device disclosed in the patent publication number CN111021364A, which includes a support pile and a corbel. A steel reinforcement cage is arranged in the support pile, a steel reinforcement member is arranged in the steel reinforcement cage, a first steel bar is arranged in the corbel and is connected to the steel reinforcement member, the steel reinforcement member includes a first embedded steel bar and a first embedded spare steel bar, and the connection ends of the first embedded steel bar and the first embedded spare steel bar corresponding to the same connection end of the first steel bar have a vertical spacing S. The design of the first embedded steel bar and the first embedded spare steel bar solves the problem of difficulty in vertical embedding of steel bars in underground spaces. When the position of the embedded steel bar is deviated, the spare steel bar can be used for connection, effectively solving the adverse effects brought by the vertical positioning deviation of the steel reinforcement cage. The structure is reasonable, convenient for construction, and can be widely applied in the technical field of building foundation pit engineering.

[0004] However, during the use of the above device, due to the setting of the internal steel reinforcement cage, during use, because the construction environment at the construction site is relatively complex, and the side wall of the foundation pit is prone to deformation during the use of the foundation pit, resulting in a change in the support angle. When it is necessary to adjust the support angle and height, it is not convenient to quickly adjust, reducing the work efficiency. Therefore, in view of this situation, we propose a more convenient and practical support device to meet the use requirements. Summary of the Invention

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] During the construction process, support equipment is required. The support equipment provided by the present invention is specifically used for the foundation pit support operation during the construction process. During the process of using this equipment for support operation, when operating the adjusting mechanism 3, force should be applied slowly and evenly to avoid sudden strong operation causing damage to the device or injury to personnel. When using the pressure sensor 403 to monitor the contact force between the first protective plate 301 and the second protective plate 402 and the foundation pit wall in real time, the sensitivity and accuracy of the pressure sensor 403 need to be checked regularly to ensure that it can work normally and provide accurate data. When making fine adjustments, the support state of the foundation pit should be carefully observed to ensure that the adjusted support effect reaches the best.

[0025] As Figures 1 - 5 shown, the present invention provides a foundation pit support device, including a fixing mechanism 1 for fixing the foundation pit support device; a support mechanism 2 is arranged on one side of the top of the fixing mechanism 1 for adjusting the support height; an adjusting mechanism 3 is arranged on one side of the support mechanism 2 for adjusting the support angle; and protection mechanisms 4 are arranged on both sides of the adjusting mechanism 3.

[0026] The protection mechanism 4 includes a connecting shaft 401. One end of the connecting shaft 401 is fixedly connected to a second protection plate 402.

[0027] As Figure 2 shown, the fixing mechanism 1 includes a bottom plate 101. Both sides of the bottom of the bottom plate 101 are fixedly connected to support blocks 102. A support block through hole (not marked in the figure) is formed in the center of the top of the support block 102. A first insertion rod 103 is inserted into the support block through hole. Bottom plate through holes (not marked in the figure) are formed on both sides of the top of the bottom plate 101. A second insertion rod 104 is inserted into the bottom plate through holes. One end of the second insertion rod 104 is fixedly connected to a fixing plate 105. The center of the top of the fixing plate 105 is fixedly connected to a connecting plate 106. The center of the top of the bottom plate 101 is fixedly connected to a support frame 107. A support frame through hole (not marked in the figure) is formed in the center of the top of the support frame 107. A first screw rod 108 is rotatably connected to the support frame through hole. A first bevel gear 109 is rotatably connected to the center of the top of the support frame 107. The first bevel gear 109 and the first screw rod 108 are threadedly connected. A second bevel gear 110 is rotatably connected to one side of the top of the support frame 107. The teeth of the first bevel gear 109 and the second bevel gear 110 are meshed with each other.

[0028] It should be noted that during use, first insert the first insertion rod 103 into the ground through the support block 102, and then a motor (not marked in the figure) drives the second bevel gear 110 to rotate and makes the first screw rod 108 rotate through the first bevel gear 109, and drives the connecting plate 106 and the fixing plate 105 to move up and down along the support frame 107, so that the second insertion rod 104 is inserted into the ground. The fixing mechanism 1 can be quickly fixed without the need for workers to tamp and fix, saving time and effort and making the use of the support device more convenient.

[0029] As Figure 3As shown in the figure, the support mechanism 2 includes a fixed frame 201 which is connected to the bottom plate 101. On one side of the fixed frame 201, a support plate 202 is rotatably connected. On one side of the support plate 202, a notch (not marked in the figure) is provided, and a sliding plate 203 is slidably connected in the notch. On one side of the top of the support plate 202, a support plate through hole (not marked in the figure) is provided, and a second screw 204 is rotatably connected in the support plate through hole. The second screw 204 is threadedly connected to the sliding plate 203. In the center of one side of the sliding plate 203, a sliding plate through hole (not marked in the figure) is provided, and a rotating shaft 205 is rotatably connected in the sliding plate through hole. One end of the rotating shaft 205 is fixedly connected with a ball 206, and the other end is fixedly connected with a third bevel gear 207. On one side of the top of the sliding plate 203, a mounting plate 208 is fixedly connected. On one side of the mounting plate 208, a fourth bevel gear 209 is rotatably connected. The teeth of the fourth bevel gear 209 and the third bevel gear 207 are meshed with each other. On both sides of the support plate 202, first connection blocks 210 are fixedly connected. On one side of the first connection block 210, a first rotating block 211 is rotatably connected. On one side of the first rotating block 211, a first cylinder 212 is installed. On one side of the first cylinder 212, a first fixing block 213 is rotatably connected. The first fixing block 213 is connected to the bottom plate 101.

[0030] It should be noted that during use, when it is necessary to adjust the support height and angle, first, a motor (not marked in the figure) drives the second screw 204 to rotate, so that the sliding plate 203 moves up and down along the support plate 202 to adjust the height. Then, a locking motor (not marked in the figure) on the mounting plate 208 drives the fourth bevel gear 209 to rotate, and drives the rotating shaft 205 and the ball 206 to rotate through the third bevel gear 207 to adjust the support angle. Finally, with the cooperation of the first connection block 210 and the first rotating block 211, the first cylinder 212 is started and under the action of the first fixing block 213 and the fixed frame 201, the angle of the support plate 202 is adjusted. The support mechanism 2 can expand the support contact area, make the support action more flexible, and improve the support efficiency.

[0031] As Figure 4 shown in the figure, the adjusting mechanism 3 includes a first protective plate 301. On both sides of the first protective plate 301, second fixing blocks 302 are fixedly connected. The second fixing blocks 302 are rotatably connected to the connecting shaft 401. At the four corners of the first protective plate 301, second connection blocks 303 are fixedly connected. On one side of the second connection block 303, a second rotating block 304 is rotatably connected. On one side of the second rotating block 304, a second cylinder 305 is installed. On one side of the second cylinder 305, a fixing ring 306 is rotatably connected. The fixing ring 306 is connected to the rotating shaft 205. In the middle of one side of the first protective plate 301, an adjusting block 307 is fixedly connected. The adjusting block 307 is in rolling connection with the ball 206.

[0032] It should be noted that during the use process, when the side wall of the foundation pit deforms, first, the adjusting block 307 and the first protection plate 301 are driven to rotate under the action of the rolling ball 206. Then, under the action of the second connecting block 303 and the second rotating block 304, the second air cylinder 305 is started at the same time. Finally, the angle of the first protection plate 301 is adjusted under the action of the fixing ring 306, and the support mechanism 2 realizes the dynamic adjustment of the support angle, avoiding the problem of local stress concentration caused by the fixed angle of the traditional rigid support and improving the support safety.

[0033] As Figure 5 shown, the adjusting assembly includes a third screw rod 406, which is rotatably connected between the third screw rod 406 and the third rotating block 405. One end of the third screw rod 406 is slidably connected with a rotating plate 407. The top of the rotating plate 407 is rotatably connected with a mounting block 408, and the mounting block 408 is connected to the first protection plate 301. One side of the rotating plate 407 is rotatably connected with a first spur gear 409, and the first spur gear 409 is threadedly connected to the third screw rod 406. One side of the rotating plate 407 is rotatably connected with a second spur gear 410, and the teeth of the second spur gear 410 are meshed with the teeth of the first spur gear 409.

[0034] It should be noted that during the use process, first, the pressure sensor 403 monitors the contact force between the first protection plate 301 and the second protection plate 402 and the foundation pit wall in real time. Then, the motor (not marked in the figure) drives the second spur gear 410 to rotate and makes the third screw rod 406 rotate through the first spur gear 409. At the same time, under the action of the rotating plate 407 and the mounting block 408, the third screw rod 406 makes the third rotating block 405 adjust the angle, and under the action of the third fixing block 404 and the connecting shaft 401, the angle of the second protection plate 402 is adjusted. The protection mechanism 4 can further finely adjust the angle of the protection plate to meet the requirements of different working conditions.

[0035] During use, first insert the first insertion rod 103 into the ground through the support block 102. Then, a motor (not marked in the figure) drives the second bevel gear 110 to rotate, and through the first bevel gear 109, the first screw rod 108 rotates, driving the connecting plate 106 to insert the second insertion rod 104 into the ground. At the same time, when it is necessary to adjust the support height and angle, the motor (not marked in the figure) drives the second screw rod 204 to rotate, causing the sliding plate 203 to move up and down to adjust the height. Then, the locking motor (not marked in the figure) on the mounting plate 208 drives the fourth bevel gear 209 to rotate. When the side wall of the foundation pit deforms, the third bevel gear 207 drives the rotating shaft 205 and the ball 206 to rotate, driving the adjusting block 307 and the first protective plate 301 to rotate. Then, under the action of the second connecting block 303 and the second rotating block 304, at the same time, the second cylinder 305 starts, and under the action of the fixed ring 306, the angle of the first protective plate 301 is adjusted to adjust the support angle. Finally, the pressure sensor 403 monitors the contact force between the first protective plate 301 and the second protective plate 402 and the foundation pit wall. Then, the motor (not marked in the figure) drives the second spur gear 410 to rotate and through the first spur gear 409, the third screw rod 406 rotates. At the same time, under the action of the rotating plate 407 and the mounting block 408, the third screw rod 406 causes the third rotating block 405 to adjust the angle, and under the action of the third fixing block 404 and the connecting shaft 401, the angle of the second protective plate 402 is adjusted. This device adjusts the support angle and height to make the protective plate fit the inclination angle of the side wall of the foundation pit, improving the support fitting degree.
