DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1-3As shown, a civil engineering construction foundation pit anti-collapse support device includes a mounting platform 1, which is characterized in that: a support plate 2 is rotatably connected to the front end of the mounting platform 1, a mounting groove 3 is opened in the middle of the rear end of the support plate 2, and a support component 4 is fixedly installed in the middle of the upper end of the mounting platform 1. Through the arranged support component 4, the foundation pit is supported and fixed with the assistance of the support plate 2, and a fixing component 5 is fixedly installed at the corner of the upper end of the mounting platform 1. Through the arranged fixing component 5, while the support component 4 and the support plate 2 support and fix the foundation pit, the fixing component 5 is driven to be propped open in the soil, so that the entire device is stably connected to the ground, thereby improving the stability of the device and the supporting force of the device.

[0029] In order to achieve the purpose of supporting and fixing the foundation pit at multiple angles, refer to Figure 1-5 The support assembly 4 includes two fixed platforms 41, and the two fixed platforms 41 are fixedly connected to the rear side of the middle part of the upper end of the mounting platform 1. The front sides of the middle parts of the left ends and the front sides of the middle parts of the right ends of the two fixed platforms 41 are rotatably connected with a transmission rod 42. The right end of the transmission rod 42 extends to the right end of the right fixed platform 41. A support rod 43 is fixedly connected to the middle part of the outer surface of the transmission rod 42. The front end of the support rod 43 is rotatably connected to a support head 44. The front end of the support head 44 is rotatably connected to a slide plate 45. The slide plate 45 is slidably connected to the inner cavity of the mounting groove 3. A limiting assembly 46 is slidably installed on the right end of the fixed platform 41 on the right.

[0030] Furthermore, the limiting assembly 46 includes a knob 461, which is fixedly connected to the right end of the transmission rod 42, a slide groove 1 462 is provided on the front side of the upper end of the fixed platform 41 located on the right side, a push rod 463 is slidably connected to the inner cavity of the slide groove 1 462, a fixing rod 464 is fixedly connected to the upper side of the right end of the push rod 463, a limiting card 465 is rotatably connected to the right side of the outer surface of the fixing rod 464, a torsion spring 466 is fixedly connected to the right end of the limiting card 465, a slide groove 2 467 is provided on the front side of the upper end of the fixed platform 41 located on the right side, the slide groove 2 467 is located at the rear side of the slide groove 1 462, a blocking plate 468 is slidably connected to the inner cavity of the slide groove 2 467, the front end of the blocking plate 468 is fixedly connected to the middle part of the outer surface of the slide groove 1 462, the right end of the torsion spring 466 is fixedly connected to the slide groove 2 467, a ratchet 469 is rotatably connected to the right side of the outer surface of the transmission rod 42, and the ratchet 469 is located on the left side of the knob 461.

[0031] Furthermore, the front end of the support plate 2 is fixedly connected with a plurality of evenly distributed rivets 21 .

[0032] By turning the knob 461 clockwise, the knob 461 drives the transmission rod 42 to rotate. As can be seen from the above, the support rod 43 is fixedly connected to the middle part of the outer surface of the transmission rod 42, so the transmission rod 42 can drive the support rod 43 to rotate at the same time, and the front end of the support rod 43 is rotatably connected to the support head 44, and the support head 44 is rotatably connected to the slide plate 45, and the slide plate 45 is slidably connected to the mounting groove 3 opened in the middle part of the rear end of the support plate 2. Therefore, when the support rod 43 rotates clockwise, the slide plate 45 slides downward in the mounting groove 3, so that the support rod 43 drives the slide plate 45 to push the support plate 2 forward to the desired angle, and then the several evenly distributed rivets 21 fixedly connected to the front end of the support plate 2 can be directly inserted into the foundation pit, thereby improving the support for the foundation pit;

[0033] In order to prevent the foundation pit from exerting too much pressure on the support plate 2, causing the support rod 43 to move in the opposite direction, the present solution solves this problem by providing a limit assembly 46;

[0034] By providing a second slide groove 467 at the front side of the upper end of the limiting component 46 on the right side, and slidably installing a blocking plate 468 in the inner cavity of the second slide groove 467, when the transmission rod 42 is forced to drive the ratchet 469 to rotate in the opposite direction, since the blocking plate 468 can only slide in the second slide groove 467, when the ratchet 469 rotates in the opposite direction, when the tooth pattern on its surface contacts the limiting card 465, the limiting card 465 can only maintain a vertical state under the blocking effect of the blocking plate 468, so that the torsion spring 466 plays a role in blocking the reverse rotation of the ratchet 469, and when the ratchet 469 rotates clockwise, since the right end of the limiting card 465 is fixedly connected to the torsion spring 466, and the right end of the torsion spring 466 is fixedly connected to the second slide groove 467, when the ratchet 469 rotates clockwise, the limiting card 465 can automatically return to the initial state under the action of the torsion spring 466;

[0035] If the support rod 43 needs to be rotated in the opposite direction, the personnel can push the push rod 463 from the slide groove 462 to the right. As can be seen from the above, a fixing rod 464 is fixedly connected to the upper side of the right end of the push rod 463, and the outer surface of the fixing rod 464 is rotatably connected to the limit card 465 on the right side, and the front end of the blocking plate 468 is fixedly connected to the middle part of the outer surface of the slide groove 462. Therefore, when the push rod 463 slides to the right, it can drive the above components to move to the right at the same time, so that the torsion spring 466 no longer limits the reverse rotation of the ratchet 469, and then the personnel can reversely rotate the knob 461 to make the transmission rod 42 drive the support rod 43 to rotate in the opposite direction. When it is rotated to the required angle, the personnel only needs to slide the push rod 463 to the left to the initial state, so that the device can be adjusted at multiple angles, thereby improving the versatility of the device.

[0036] To achieve a stable connection to the ground; see Figure 1-3 and Figure 6-7 The four fixing components 5 each include a shell 51. A rectangular groove 52 communicating with the inner cavity is provided on the left and right sides of the outer surface of the shell 51. A cone head 53 is fixedly connected to the lower end of the shell 51. The lower parts of the inner surfaces of the two rectangular grooves 52 are rotatably connected to expansion plates 54. A transmission plate 55 is slidably connected to the inner surface of the shell 51. One end of the transmission plate 55 is slidably matched with the two expansion plates 54 respectively. A threaded rod 56 extending to the upper end of the shell 51 is rotatably connected to the middle part of the upper end of the cone head 53. The outer surface of the threaded rod 56 is threadedly connected to the middle part of the upper end of the transmission plate 55.

[0037] Furthermore, the inclination of the upper portions of the two expansion plates 54 is greater than the inclination of the lower portions, and the transmission plate 55 is adapted to the inclination of the lower portions of the two expansion plates 54 .

[0038] Furthermore, the outer surfaces of the two expansion plates 54 are fixedly connected with a plurality of cone pins 541 distributed in an array.

[0039] By driving four cone heads 53 into the soil at four corners of the upper end of the mounting platform 1, respectively, when the cone heads 53 are driven into the soil, a person can rotate the threaded rod 56. It can be seen from the above that the transmission plate 55 is slidably connected between the inner walls of the mounting platform 1, and the threaded rod 56 is threadedly connected to the middle part of the upper end of the transmission plate 55. Therefore, when the threaded rod 56 rotates, the transmission plate 55 can only convert the rotational motion into a linear motion. Subsequently, when the transmission plate 55 moves upward, one end of the transmission plate 55 is respectively connected to the two expansion plates 54. The two expansion plates 54 are adapted to slide, and the upper inclination of the two expansion plates 54 is greater than the lower inclination, and the transmission plate 55 is adapted to the lower inclination of the two expansion plates 54, so when the transmission plate 55 slides upward, the transmission plate 55 can squeeze and expand the two expansion plates 54 outward at the same time. When the expansion plates 54 are squeezed and expanded outward, since the outer surfaces thereof are fixedly connected with a plurality of array-distributed cone nails 541, the expansion plates 54 can drive the cone nails 541 into the soil, thereby improving the stable connection and support between the device and the ground;

[0040] If the entire device of the fixing assembly 5 needs to be retracted, the threaded rod 56 only needs to be rotated counterclockwise, and then the threaded rod 56 drives the transmission plate 55 to move downward. At the same time, the transmission plate 55 can pull the expansion plate 54 back to the initial state, so that the device can be repeatedly used, thereby improving the utilization rate of the device.

[0041] like Figure 7 , the transmission plate 55 is arranged in a cross shape.

[0042] As can be seen from the above, during use of this solution, by setting the transmission plate 55 in the shape of a cross 1, the transmission plate 55 can simultaneously perform the functions of limiting and sliding connection, thereby making the operation of subsequent devices more consistent.

[0043] The working principle of the utility model is as follows: firstly, the mounting platform 1 is placed at the corresponding position, and then four cone heads 53 are driven downward into the soil at the four corners of the mounting platform 1. Then, a person rotates the threaded rod 56 so that the threaded rod 56 drives the transmission plate 55 to move upward, so that the transmission plate 55 squeezes the two expansion plates 54 outward, thereby causing the expansion plates 54 to expand outward. Then, a plurality of cone nails 541 fixedly connected to the outer surfaces of the two expansion plates 54 can be driven into the soil, thereby improving the stable connection between the device and the ground.

[0044] Then, the personnel can rotate the knob 461 clockwise according to the required angle, so that the knob 461 drives the transmission rod 42 to rotate, and then the transmission rod 42 drives the support rod 43, the support head 44, and the slide plate 45 to rotate, and the slide plate 45 is rotatably connected to the support head 44, and the slide plate 45 is slidably connected to the inner cavity of the installation groove 3. Therefore, when the slide plate 45 slides downward, the support rod 43 can move the support plate 2 to the required angle through the slide plate 45. When it moves to the required angle, the rivets 21 fixedly connected to the front end of the support plate 2 can be driven into the foundation pit, thereby improving the overall support performance;

[0045] When the transmission rod 42 rotates clockwise, since the right end of the limit card 465 is fixedly connected to the torsion spring 466, and the right end of the torsion spring 466 is fixedly connected to the second slide slot 467, when the ratchet 469 rotates clockwise, the limit card 465 can automatically return to the initial state under the action of the torsion spring 466, and the second slide slot 467 can block the torsion spring 466 to prevent the torsion spring 466 from rebounding excessively and causing counterclockwise rotation, thereby achieving the desired angle fixation;

[0046] If reverse rotation is required, the operator can push the push rod 463 from the slide groove 462 to the right, and the slide groove 462 can drive the components connected to it to move to the right at the same time, so that the torsion spring 466 no longer limits the reverse rotation of the ratchet 469. Then the operator can reversely rotate the knob 461 to make the transmission rod 42 drive the support rod 43 to rotate in the reverse direction.

[0047] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
