Specific embodiments

[0020] 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 efforts shall fall within the protection scope of the present invention. Embodiment

[0021] Refer to Figure 1 、 2 For the first embodiment of the present invention, this embodiment provides a quick installation device for a pipeline trench support formwork, including two retaining plates 1. The opposite end faces of the two retaining plates 1 are respectively fixedly connected with profiled steel purlins 2. A supporting part 3 is arranged on the top of the profiled steel purlin 2, and a supporting part 4 is connected to the opposite sides of the supporting part 3.

[0022] By using bolt connection instead of traditional welding with the steel purlin, the profiled steel purlin 2 and the supporting part 4 are quickly installed by overlapping through the supporting part 3. It can not only support the retaining plate 1, but also avoid the risk of steel support falling off. The operation method is simple and easy for construction workers to master. After the trench construction is completed, it can be quickly disassembled, greatly improving the installation efficiency. Embodiment

[0023] Refer to Figures 1-3 For the second embodiment of the present invention, this embodiment is based on the previous embodiment. Specifically, the supporting part 3 includes a supporting plate 31 and a reinforcing rib 32. One side of the supporting plate 31 is fixedly connected to the supporting part 4 by bolts, and several reinforcing ribs 32 are fixedly connected to the inner side of the supporting plate 31. It is connected to the whole through bolts and the supporting part 4 to form a supporting member that can be erected on the profiled steel purlin. The bolt connection has high work efficiency, good stability and is convenient for disassembly and assembly.

[0024] Furthermore, the supporting plate 31 is of an L-shaped structure, and the reinforcing rib 32 is of a right-angled triangular prism structure. The structure of the right-angled triangular prism improves the supporting strength of the supporting plate 31.

[0025] Specifically, the profiled steel purlin 2 is in a long strip shape and is an I-beam.

[0026] Specifically, the support part 4 includes a movable cylinder 41, a first flange 42, a limit component 43, a second flange 44, a protection cylinder 45, fixing bolts 46, a support column 47, positioning holes 48, and a third flange 49. Both ends of the protection cylinder 45 are respectively fixedly connected with the second flange 44. One side of the second flange 44 is fixedly connected with the supporting part 3 through the fixing bolt 46, and the other side of the second flange 44 is fixedly connected with the first flange 42 through the fixing bolt 46. The first flange 42 is fixedly sleeved on one end of the support column 47. The support column 47 is slidably sleeved in the movable cylinder 41. One end of the movable cylinder 41 away from the first flange 42 is fixedly connected with the third flange 49. The third flange 49 is fixedly connected with the supporting part 3 through the fixing bolt 46. A plurality of positioning holes 48 are respectively formed on both sides of the movable cylinder 41. The limit component 43 is slidably clamped in the positioning hole 48, and the limit component 43 is slidably connected with the support column 47.

[0027] By the limit component 43 disengaging from the positioning hole 48, the movable cylinder 41 can move, thereby changing the length of the support part 4 for use in grooves of different widths.

[0028] Furthermore, the limit component 43 includes a cylindrical clamping block 431, a limit disc 432, a spring 433, and a movable groove 434. The movable groove 434 is formed on the side of the support column 47 away from the first flange 42. The spring 433 is movably arranged in the movable groove 434. Both ends of the spring 433 are respectively fixedly connected with the limit disc 432. The limit disc 432 is slidably sleeved in the movable groove 434. The opposite ends of the limit disc 432 are respectively fixedly connected with the cylindrical clamping block 431. The cylindrical clamping block 431 is in clamping fit with the positioning hole 48.

[0029] When operating the limit component 43, manually press the cylindrical clamping block 431 to compress the spring 433. At the same time, the cylindrical clamping block 431 retracts into the movable groove 434, and at the same time, the cylindrical clamping block 431 disengages from the clamping of the positioning hole 48. Thus, the movable cylinder 41 can be telescopically moved. After moving to a suitable position, under the elastic force of the spring 433, the cylindrical clamping block 431 is again inserted into the movable groove 434 to limit and fix the position of the movable cylinder 41. Embodiment

[0030] Refer to Figures 1-3 , which is the third embodiment of the present utility model. Based on the above two embodiments, during use, bolt connection is used instead of traditional welding with the steel purlin. The structure between the profiled steel purlin 2 and the support part 4 is quickly installed through the lap joint of the supporting part 3. It can not only support the retaining plate 1 but also avoid the risk of steel support falling off. The operation method is simple, and it is easy for construction workers to master. It can be quickly disassembled after the groove construction is completed, greatly improving the installation efficiency. The length of the support part 4 can be adjusted, thereby facilitating the support for grooves of different widths.
