[0002] The pipeline foundation pit support technology in building construction is a key link to ensure construction safety and prevent soil erosion. Traditional pipeline foundation pit support methods, such as steel supports and concrete supports, can basically meet the construction requirements, but there are limitations in flexibility and efficiency. During the actual construction process, it is necessary to customize the support structure according to the specific size of the foundation pit and meet the construction requirements through a complex adjustment process; especially in narrow spaces, such as inside a pipeline foundation pit, it is difficult to adjust these traditional support structures and the operation is complex.

[0003] Therefore, there is an urgent need for a support device that can be flexibly adjusted and quickly adapt to foundation pits of different depths and widths to improve construction efficiency and safety. Utility Model Content

[0004] In order to improve the adjustment flexibility of the pipeline foundation pit support structure, this application provides a pipeline foundation pit support structure that is easy to adjust.

[0005] The pipeline foundation pit support structure that is easy to adjust provided by this application adopts the following technical solution:

[0006] A pipeline foundation pit support structure that is easy to adjust includes a foundation pit body. On both sides of the upper part inside the foundation pit body, fixed rods are symmetrically arranged. In the middle of the outer parts of the two fixed rods, a bidirectional threaded rod is rotatably connected. On the bidirectional threaded rod, connection blocks are threadedly connected. There are two groups of connection blocks symmetrically arranged with respect to the bidirectional threaded rod. On both side surfaces of each connection block close to the inner wall of the foundation pit body, connecting rods are hinged. At one end of each connecting rod away from the connection block, a first push rod is hinged. On the end face of the fixed rod close to the inner wall of the foundation pit body, a second push rod is slidably arranged. Inside the fixed rod, a driving component is arranged for driving the second push rod to move. On the end face of the first push rod and the second push rod close to the inner wall of the foundation pit body, a first support plate is arranged. At the bottom of the first support plate, a second support plate is arranged. The first support plate is slidably arranged inside the second support plate. Inside the second support plate, an adjusting component is arranged for adjusting the first support plate. Inside the second support plate, a first sliding groove for sliding cooperation with the first support plate is opened.

[0007] By adopting the above technical solution, the operator first measures the accurate data of the depth and width of the pipeline foundation pit; the operator places the support structure in the pipeline foundation pit, and then the operator uses the adjustment component to move the first support plate in the first sliding groove, and then takes out the first support plate from the second support plate and adjusts it to a suitable height; then the operator uses the mechanical structure to drive the bidirectional threaded rod to drive the two connecting blocks to approach each other, and the connecting block pushes the first push rod through the connecting rod to squeeze and fix the first support plate; then the operator uses the driving component to drive the second push rod to move to realize the secondary extrusion and fixation of the first support plate; the operator improves the adjustment flexibility of the pipeline foundation pit support structure by adjusting the position of the first support plate and flexibly pushing the positions of the first push rod and the second push rod.

[0008] Preferably, the driving component includes a crown gear rotatably arranged inside the fixed rod, a driven gear rotatably arranged inside the fixed rod, and a transmission screw threadedly connected to the second push rod. The crown gear is sleeved on the outer peripheral surface of the bidirectional threaded rod, and the transmission screw is fixedly connected to the driven gear.

[0009] By adopting the above technical solution, the operator drives the bidirectional threaded rod to rotate through the mechanical structure, the rotation of the bidirectional threaded rod drives the crown gear to rotate, the rotation of the crown gear drives the driven gears on both sides to rotate, and the rotation of the driven gear drives the transmission screw to rotate, thereby driving the second push rod to move towards the first support plate, which is convenient for the operator to realize the secondary extrusion of the first support plate.

[0010] Preferably, an anti-slip-off plate is arranged on the end face of the second push rod close to the bidirectional threaded rod, and a second sliding groove for the anti-slip-off plate to slide and cooperate is opened in the fixed rod.

[0011] By adopting the above technical solution, the movement of the second push rod drives the anti-slip-off plate to move in the second sliding groove, and the setting of the anti-slip-off plate can effectively prevent the second push rod from sliding out of the fixed rod.

[0012] Preferably, fixing plates are arranged on the end faces of the first push rod and the second push rod close to the first support plate, and the fixed rod abuts against the first support plate.

[0013] By adopting the above technical solution, the setting of the fixing plates increases the contact area between the first push rod and the second push rod and the second support plate, thereby improving the fixing effect on the second support plate.

[0014] Preferably, the adjusting assembly includes a first ratchet plate disposed on both side surfaces of the first support plate, a second ratchet plate movably disposed in the second support plate, and an adjusting spring fixedly connected to the second ratchet plate. The first ratchet plate and the second ratchet plate are meshed and cooperated with each other. A third sliding groove for the second ratchet plate to slide and cooperate is formed in the second support plate. A plurality of groups of adjusting springs are uniformly arranged along the length direction of the second ratchet plate, and the end surface of the adjusting spring away from the second ratchet plate is fixedly connected to the inner wall of the third sliding groove.

[0015] By adopting the above technical solution, the operator pulls the first support plate upward, and the first support plate drives the first ratchet plate to move upward together. During this process, when the first ratchet plate and the second ratchet plate cooperate with each other, the second ratchet plate reciprocates in the third sliding groove, and the adjusting spring switches back and forth between the compressed state and the normal state until the second support plate moves to a specific height.

[0016] Preferably, a pull rod is fixedly connected to the tail of the second ratchet plate.

[0017] By adopting the above technical solution, the operator drives the second ratchet plate to move in the third sliding groove by pulling the pull rod until the first ratchet plate and the second ratchet plate are separated, and the positioning spring is in a compressed state. At this time, the operator can quickly pull the second support plate to a specific position, and then release the pull rod. The second ratchet plate pops out and meshes with the first ratchet plate under the action of the elastic force of the adjusting spring to realize the fixation of the second support plate; when the operator needs to retract the second support plate, only need to pull the pull rod to unlock the locking of the first ratchet plate, and the second support plate quickly retracts under the action of gravity.

[0018] Preferably, a bottom plate is fixedly connected to the side of the second support plate away from the inner wall of the foundation pit body, and a plurality of groups of reinforcing ribs are arranged between the bottom plate and the second support plate.

[0019] By adopting the above technical solution, the setting of the bottom plate and the reinforcing ribs strengthens the supporting effect of the first support plate on the bottom of the foundation pit body.

[0020] Preferably, a plurality of anchor rods are uniformly penetrated through the bottom plate, and the tail ends of the anchor rods are arranged inside the foundation pit body.

Specific implementation manner

[0031] The following will further elaborate on this application in conjunction with the attached Figures 1-4 drawings.

[0032] The embodiment of this application discloses a pipeline foundation pit support structure that is easy to adjust. Referring to Figure 1 , a pipeline foundation pit support structure that is easy to adjust includes a foundation pit body 1. Fixed rods 11 are symmetrically arranged on both sides above the foundation pit body 1. The fixed rods 11 are horizontally arranged, and a bidirectional threaded rod 12 is rotatably connected to the middle of the outside of the fixed rods 11. The bidirectional threaded rod 12 is horizontally arranged, and connecting blocks 13 are threadedly connected to the bidirectional threaded rod 12. There are two groups of connecting blocks 13 with respect to the bidirectional threaded rod 12. Connecting rods 14 are hinged on both side surfaces of the connecting blocks 13 close to the inner wall of the foundation pit body 1. One end of the connecting rod 14 far from the connecting block 13 is hinged with a first push rod 15. The end surface of the fixed rod 11 close to the inner wall of the foundation pit body 1 is slidably provided with a second push rod 16. A first support plate 17 is arranged on the end surfaces of the first push rod 15 and the second push rod 16 close to the inner wall of the foundation pit body 1. A second support plate 18 is arranged at the bottom of the first support plate 17, and the first support plate 17 is slidably arranged on the second support plate 18.

[0033] The operator drives the bidirectional threaded rod 12 to rotate through a mechanical structure. The rotation of the bidirectional threaded rod 12 drives the two groups of connecting blocks 13 to approach each other. The connecting blocks 13 push the first push rod 15 through the connecting rods 14 to squeeze and fix the first support plate 17.

[0034] Referring to Figure 2 , Figure 3 , a driving assembly 2 for driving the second push rod 16 to move is arranged in the fixed rod 11. The driving assembly 2 includes a crown gear 21, a driven gear 22 and a transmission screw rod 23. The crown gear 21 is sleeved on the bidirectional threaded rod 12, and the crown gear 21 is rotatably arranged in the fixed rod 11. The driven gear 22 is rotatably arranged in the fixed rod 11. The transmission screw rod 23 is threadedly connected to the second push rod 16, and the driven gear 22 is sleeved on the outer peripheral surface of the transmission screw rod. The crown gear 21 and the transmission screw rod 23 are meshed with each other.

[0035] The operator drives the bidirectional threaded rod 12 to rotate through the mechanical structure. The rotation of the bidirectional threaded rod 12 drives the crown gear 21 to rotate. The crown gear 21 drives the transmission lead screw 23 to rotate through the driven gear 22, and then drives the second push rod 16 to extrude and fix the first support plate 17 again.

[0036] Referring to Figure 2 , an anti - detachment plate 161 is arranged on the end face of the second push rod close to the bidirectional threaded rod 12. The anti - detachment plate 161 is fixedly connected to the second push rod 16. A second sliding groove 111 is formed in the fixed rod 11, and the inner wall of the second sliding groove 111 is in sliding fit with the outer wall of the anti - detachment plate 161. The setting of the anti - detachment plate 161 can effectively prevent the second push rod 16 from sliding out of the fixed rod 11.

[0037] Referring to Figure 4 , an adjusting assembly 3 for adjusting the first support plate 17 is arranged in the second support plate 18. The adjusting assembly 3 includes a first ratchet plate 31, a second ratchet plate 32 and an adjusting spring 33. The first ratchet plate 31 is fixedly connected to both side faces of the first support plate 17. The second ratchet plate 32 is slidably arranged in the second support plate 18. A third sliding groove 182 is formed in the second support plate 18, and the inner wall of the third sliding groove 182 is in sliding fit with the outer wall of the second ratchet plate 32. The first ratchet plate 31 and the second ratchet plate 32 are meshed and matched. The adjusting spring 33 is horizontally arranged, one end of the adjusting spring 33 is fixedly connected to the second ratchet plate 32, and the other end is fixedly connected to the inner wall of the third sliding groove 182.

[0038] When the operator pulls up the second support plate 18, the second layer plate drives the first ratchet plate 31 to move upward together. In this process, during the cooperation between the first ratchet plate 31 and the second ratchet plate 32, the second ratchet plate 32 reciprocates in the third sliding groove 182, and the adjusting spring 33 switches back and forth between the compressed state and the normal state until the second support plate 18 moves to a specific height.

[0039] Referring to Figure 4 , a pull rod 34 is fixedly connected to the tail of the second ratchet plate 32. The operator can drive the second ratchet plate 32 to move in the third sliding groove 182 by pulling the pull rod until the first ratchet plate 31 and the second ratchet plate 32 are separated, and the positioning spring is in the compressed state. At this time, the operator can quickly pull the second support plate 18 to a specific position, and then release the pull rod 34. The second ratchet plate 32 pops out and meshes with the first ratchet plate 31 under the action of the elastic force of the adjusting spring 33 to realize the fixation of the second support plate 18; when the operator needs to retract the second support plate 18, only need to pull the pull rod 34 to unlock the locking of the first ratchet plate 31, and the second support plate 18 quickly retracts under the action of gravity.

[0040] Referring to Figure 1, a fixing plate 19 is arranged at the end faces of the first push rod 15 and the second push rod 16 close to the first support plate 17. The fixing plate 19 is fixedly connected to the first push rod 15 and the second push rod 16 respectively, and the fixing rod 11 abuts against the first support plate 17. The arrangement of the fixing plate 19 increases the contact area between the first push rod 15 and the second push rod 16 and the first support plate 17, thereby improving the effect of extruding the first support plate 17.

[0041] Refer to Figure 1 , a bottom plate 4 is fixedly connected to the side of the second support plate 18 away from the inner wall of the foundation pit body 1. A plurality of groups of reinforcing ribs 41 are arranged between the bottom plate 4 and the second support plate 18. The arrangement of the bottom plate 4 and the reinforcing ribs 41 facilitates the operator to enhance the supporting effect of the first support plate 17 on the bottom of the foundation pit body 1.

[0042] Refer to Figure 1 , a plurality of anchor rods 42 are evenly penetrated through the bottom plate 4, and the tails of the anchor rods 42 are arranged inside the foundation pit body 1. The arrangement of the anchor rods 42 strengthens the stability of the bottom plate 4 and further strengthens the supporting effect of the supporting structure.

[0043] The implementation principle of a pipeline foundation pit supporting structure that is easy to adjust in the embodiment of the present application is as follows: The operator first determines the data according to the depth and width of the pipeline foundation pit; then the operator uses the meshing relationship between the first ratchet plate 31 and the second ratchet plate 32 to move the first support plate 17 in the first sliding groove 181, and then takes out the first support plate 17 from the second support plate 18 and adjusts it to a suitable height; then by driving the bidirectional threaded rod 12 to rotate, the bidirectional screw simultaneously drives the first push rod 15 and the second push rod 16 to move to both sides through the connecting block 13 and the crown gear 21 and other structures, so as to realize double-layer extrusion and fixation of the first support plate 17. The bottom plate 4, the reinforcing ribs 41 and the anchor rods 42 further strengthen the supporting ability of the supporting structure. The adjusting assembly 3 in the second support plate 18 and the flexible adjusting ability of the first push rod 15 and the second push rod 16 improve the adjusting flexibility of the pipeline foundation pit supporting structure.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
