Description

Technical Field

[0001] The present application relates to the technical field of support devices, and in particular to a pipeline trench excavation support device. Background Art

[0002] In the pipeline installation project, it is necessary to dig pipeline trenches on the ground where the pipes are buried. Burying the pipelines underground can increase the practical life of the pipelines and prevent the pipelines from being damaged by humans. When the trenches are excavated, in order to prevent the soil on both sides of the trench from falling and backfilling, the workers will use wooden boards to support the two walls of the trench.

[0003] However, the existing supporting device is a wooden board and a metal pipe. Two wooden boards are respectively attached to the groove wall, and then the metal pipe is pressed down from above so that the metal pipe is pressed between the two wooden boards. This operation requires the staff to press down hard, which is not only manpower-consuming, but also requires a wooden block or a small wooden board to be placed between the metal pipe and the wooden board if the metal pipe is not long enough. This is relatively cumbersome and inconvenient for normal use. Utility Model Content

[0020] The present application embodiment discloses a pipeline trench excavation support device. Figure 1-Figure 3A pipeline trench excavation support device includes a support base 1, a plurality of fixed columns 2 are fixed on the top of the support base 1, and a fixed top plate 3 is fixed on the top of the plurality of fixed columns 2; it also includes a long screw rod 6 and a support wall plate 7, the long screw rod 6 is driven by a driving motor 4 and installed on the fixed top plate 3 and the support base 1, the driving motor 4 is fixed on the fixed top plate 3, a moving plate 5 is screwed on the long screw rod 6, and a pair of connecting rods 8 are hinged on both sides of the moving plate 5, and two supporting wall plates 7 are respectively located on one side of the support base 1, and the two connecting rods 8 in the same direction are connected to the support base 1. The other ends are hinged on the supporting wall panels 7, and multiple fixed columns 2 pass through the movable plate 5 and are slidably connected to the movable plate 5. When the forward rotation mode of the driving motor 4 is started, the driving motor 4 drives the long screw rod 6 to rotate clockwise, thereby forcing the movable plate 5 to approach the supporting base 1. At the same time, the connecting rods 8 on both sides of the movable plate 5 will push the supporting wall panels 7 respectively, forcing the supporting wall panels 7 to move away from the supporting base 1, thereby realizing the function of the two supporting wall panels 7 being squeezed and supported on the groove wall. Starting the reverse mode of the driving motor 4 can retract the two supporting wall panels 7, which is convenient for use.

[0021] In this embodiment, if Figure 1 As shown, lifting rods 9 are fixed on both sides of the support base 1, and a plurality of lifting rings 10 are fixed on the lifting rods 9. This arrangement facilitates the transportation and handling of the device and is convenient for use.

[0022] In this embodiment, if Figure 1 and Figure 2 As shown, a pair of sliding rods 11 are fixed to the opposite sides of the two supporting wall panels 7, and a plurality of sleeve rods 12 are fixed on the supporting base 1. The sliding rods 11 are in the sleeve rods 12 and are slidably connected with the sleeve rods 12. When the supporting wall panels 7 move horizontally, the sliding rods 11 gradually extend out from the sleeve rods 12, so that the supporting wall panels 7 move stably to avoid shaking, and the sliding rods 11 and the sleeve rods 12 have a supporting and limiting function.

[0023] In this embodiment, if Figure 2 and Figure 3As shown, both sides of the top of the support base 1 are provided with limited long grooves 15, and a plurality of circular holes 18 are provided on the support base 1, and the circular holes 18 are located in the limited long grooves 15. The support base 1 also includes a cylinder 14. Both sides of the top of the support base 1 are fixed with support frames 13, and the cylinder 14 is fixed on the support frame 13.

A pair of stabilizing cones 17 are fixed at the bottom of the fixing plate 16, and the stabilizing cones 17 are vertically corresponding to the circular holes 18, and the diameter of the stabilizing cones 17 is smaller than the diameter of the circular holes 18. After the device is placed in the groove, the cylinders 14 are started respectively, and the cylinders 14 push the fixing plates 16 to move down and embed them in the limited long grooves 15, and at the same time, the stabilizing cones 17 are respectively inserted into the soil through the circular holes 18, which can improve the stability of the device and facilitate use.

[0024] The implementation principle of a pipeline trench excavation support device in an embodiment of the present application is as follows: when in use, after the device is placed in the trench, the cylinders 14 are started respectively, and the cylinders 14 push the fixed plate 16 to move down and embed it into the limiting long groove 15, and at the same time, the stabilizing cones 17 are respectively inserted into the soil through the circular holes 18, which can improve the stability of the device. Then, when the forward rotation mode of the driving motor 4 is started, the driving motor 4 drives the long screw 6 to rotate clockwise, thereby forcing the movable plate 5 to approach the supporting base 1. At the same time, the connecting rods 8 on both sides of the movable plate 5 will push the supporting wall panels 7 respectively, forcing the supporting wall panels 7 to move away from the supporting base 1, thereby realizing the function of the two supporting wall panels 7 being squeezed and supported on the trench wall.
