Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering, and in particular relates to a reusable civil engineering temporary support construction device. Background Art

[0002] In the field of civil engineering, whether it is the foundation construction of buildings, road and bridge foundation construction or the preliminary civil engineering work of other large-scale infrastructure projects, temporary support structures play a vital role. In the process of various foundation construction, such as digging deep foundation pits, and carrying out foundation operations in areas with complex terrain or unstable geological conditions, temporary support devices need to be built to prevent the collapse of the surrounding soil, maintain the structural stability of the construction area, ensure the safety of construction workers and the smooth progress of the construction process.

[0003] Traditional civil engineering temporary support structures usually use relatively simple wooden formwork, steel pipe scaffolding or disposable metal supports. Although disposable metal supports have improved the stability and convenience of support to a certain extent, their non-reusable nature leads to serious waste of resources and greatly increases project costs. At the same time, once gravel rolls down from a high slope during construction, it will directly impact the support structure and cause serious harm to the construction workers below. Moreover, since it is impossible to know the dangerous situation in time, it is difficult for the construction workers to avoid it in time, thus causing safety accidents.

[0004] Therefore, it is necessary to provide a new reusable civil engineering temporary support construction device to solve the above technical problems. Summary of the invention

[0044] The linkage mechanism further includes a linkage block 27 , a rack 28 , a gear 31 , and a limiting rod 30 .

[0045] A linkage block 27 is fixedly arranged at the left and right ends of the upper end surface of the inclined plate 4, and the two linkage blocks 27 are arranged symmetrically. A first slot 39 is arranged on the end surface of the two linkage blocks 27 close to each other, and the first slot 39 is extended along the inclined direction of the inclined plate 4, and the upper end surface of the first slot 39 remains open.

A gear 31 is fixedly arranged at the end of the rotating shaft 32 extending into the first slot 39, and a limiting rod 30 is fixedly arranged at the end of the gear 31 away from the rotating shaft 32. The limiting rod 30 is a square rod-shaped structure, and the limiting rod 30 is coaxially arranged with the rotating shaft 32. The end of the limiting rod 30 away from the gear 31 is slidably inserted into the second limiting slot 29, and the two side surfaces of the limiting rod 30 respectively maintain sliding contact with the inner walls on both sides of the second limiting slot 29.

[0048] The working principle of the present invention is:

[0049] First, the two legs 13 of the support base 1 are fixedly inserted into the ground, and the support base 1 is auxiliary supported by the two inclined support columns 12. Next, the two first positioning columns 15 on the adjustable support plate 2 are inserted into the two first positioning holes 14 on the support base 1, and then the two second bolts 11 are respectively passed through the two third fixing plates 9 and screwed to the two fourth fixing plates 10, so that the adjustable support plate 2 is fixedly connected to the support base 1. Next, the two second positioning columns 17 on the top support plate 3 are inserted into the two second positioning holes 16 on the adjustable support plate 2, and then the two first bolts 8 are respectively passed through the two first fixing plates 6 and screwed to the corresponding second fixing plates 7, so that the top support plate 3 is fixedly connected to the adjustable support plate 2.

[0050] The inclined plate 4 is rotated and adjusted according to the angle of the slope, so that the end of the inclined plate 4 away from the top support plate 3 contacts the slope, and the rebound force of the torque spring 21 ensures that the inclined plate 4 is always in contact with the slope.

[0051] When gravel rolls down the slope, part of the gravel falls onto the buffer block 20, and the first buffer spring 33 is used to buffer the impact force on the buffer block 20, so as to prevent the rolling gravel from damaging the fixed box 19. Another part of the gravel rolls down from between the two fixed boxes 19 into the inside of the stone-blocking box 5, so that the total weight of the stone-blocking box 5 increases. The stone-blocking box 5 slides downward on the inclined plate 4 through the cooperation between the limit block 25 and the first limit groove 26. During the downward sliding process, the stone-blocking box 5 drives the two moving blocks 24 to slide outward inside the lower sliding groove of the fixed box 19 through the support rope 23, so that the infrared transmitter 36 and the infrared receiver 37 are misaligned, and the infrared receiver 37 can no longer receive infrared rays, so that the signal is transmitted to the controller, and the controller controls the alarm 18 to sound an alarm, reminding the staff to come and deal with the fallen rocks collected inside the stone-blocking box 5.

[0052] During the downward sliding of the stone-blocking box 5, the stone-blocking box 5 drives the two rotating shafts 32 on the box door 22 to slide downward synchronously, the rotating shaft 32 drives the gear 31 to slide downward inside the first empty slot 39, and the gear 31 drives the limiting rod 30 to slide downward inside the second limiting slot 29. Since the two side surfaces of the limiting rod 30 respectively maintain sliding contact with the inner walls of the two sides of the second limiting slot 29, it is ensured that the limiting rod 30 does not rotate during the downward sliding of the second limiting slot 29, thereby ensuring that the box door 22 does not open. During the sliding of the limiting rod 30 inside the second limiting slot 29, the gear 31 has not yet meshed with the rack 28.

[0053] As the falling rocks collected in the stone retaining box 5 gradually increase, the second buffer spring 34 continues to stretch, and the stone retaining box 5 continues to slide downward, so that the limiting rod 30 enters the second empty slot 38 from the second limiting slot 29, and the gear 31 begins to mesh with the rack 28. As the width of the second empty slot 38 increases, and the gear 31 meshes with the rack 28, as the stone retaining box 5 continues to slide downward, the gear 31 begins to rotate, the gear 31 drives the rotating shaft 32 to rotate, the rotating shaft 32 drives the box door 22 to rotate, and the box door 22 gradually opens, and the falling rocks collected in the stone retaining box 5 are discharged from the opened box door 22. The stones rolling down the slope will not hit the foundation workers, reducing casualties.

[0054] As the falling rocks are continuously discharged, the weight of the stone-blocking box 5 gradually decreases. Under the rebound force of the second buffer spring 34, the stone-blocking box 5 starts to slide upward on the inclined plate 4, and the stone-blocking box 5 drives the shaft 32 of the door 22 to slide upward. The shaft 32 drives the gear 31 to slide upward. Under the cooperation of the gear 31 and the rack 28, the gear 31 starts to rotate in the opposite direction, and the door 22 gradually closes. When the limiting rod 30 enters the second limiting groove 29 from the second empty groove 38, the gear 31 is disengaged from the rack 28, and the door 22 is completely closed. Under the rebound force of the second buffer spring 34, the limiting rod 30 slides to the inner high position of the second limiting groove 29. The device as a whole returns to its initial state.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
