Description

Technical Field

[0001] This utility model relates to a trench support device, belonging to the technical field of support equipment. Background Technology

[0002] A trench is a square channel excavated for laying various pipes or for drainage. During trench excavation, support devices are needed to protect the trench's sidewalls and prevent collapse. Current support devices generally include side wooden formwork, support frames, support rods, and support sleeves. This structure is relatively simple, but the support frame is a square frame, resulting in low overall strength and easy damage. Furthermore, the wooden formwork has poor reusability, and the bottom of the support frame is usually suspended, making installation and positioning difficult. Utility Model Content

[0003] This utility model provides a trench support device that solves the problems of the current device's support frame being a square frame, which has low overall strength, is easily damaged, has poor reusability of wooden templates, and the bottom of the support frame is generally suspended, making it difficult to install and position the support frame.

[0004] This utility model relates to a trench support device, including a side template, a support frame, a support screw rod, and a support sleeve. The outer end of the support screw rod is provided with a U-shaped clamping plate. The side template is a side steel template, which is welded and fixed to the outside of the support frame. The support frame includes two parallel side frame plates. Multiple transverse stiffeners arranged vertically are fixed between the side frame plates. Vertical stiffeners are fixed between adjacent transverse stiffeners. Reinforcing stiffeners are fixed to the inner sides of both ends of the side frame plates. The other end of the reinforcing stiffener is fixed at the intersection of the vertical stiffener and the transverse stiffener. Positioning tip plates are fixed to the bottom of the two side frame plates. The inner groove of the clamping plate cooperates with the outer wall of the transverse stiffener.

[0005] As a preferred option, the bottom of the positioning tip plate is provided with a tip bevel, which is inclined with the inside higher than the outside, to better avoid injuring the operator.

[0006] As a preferred option, the bottom outer side of the positioning tip plate is equipped with a protective sleeve to better prevent injury to the operator during transportation.

[0007] As a preferred embodiment, the two ends of the support sleeve are fixed with nuts that cooperate with the support screws. The threads of the two nuts are turned in opposite directions, and the threads of the support screws at both ends are turned in opposite directions.

[0022] Example 1, such as Figures 1 to 6 As shown, this utility model is a trench support device, including a side template 2, a support frame 3, a support screw 10, and a support sleeve 8. The outer end of the support screw 10 is provided with a U-shaped clamping plate 5. The side template 2 is a side steel template, which is welded and fixed to the outside of the support frame 3. The support frame 3 includes two parallel side frame plates 301. Multiple horizontal stiffeners 302 arranged vertically are fixed between the side frame plates 301. Vertical stiffeners 303 are fixed between adjacent horizontal stiffeners 302. Reinforcing stiffeners 304 are fixed to the inner sides of both ends of the side frame plates 301. The other end of the reinforcing stiffeners 304 is fixed at the intersection of the vertical stiffeners 303 and the horizontal stiffeners 302. The side frame plates 301, horizontal stiffeners 302, vertical stiffeners 303, and reinforcing stiffeners 304 are all made of H-shaped steel plates. The bottom of the two side frame plates 301 is fixed with a positioning tip plate 6. The inner groove of the clamping plate 5 cooperates with the outer wall of the horizontal stiffeners 302.

[0023] In use, place the support frame 3 with welded side steel templates against the side wall of the trench 1, with the side template 2 against the side wall of the trench 1. Insert the positioning tip plate 6 into the bottom soil of the trench 1. Then connect the support screw 10 to both ends of the support sleeve 8. Rotate the support screw 10 at both ends so that the clamping plate 5 is clamped on the outside of the transverse stiffener 302. Then rotate the support sleeve 8 so that the support screw 10 extends outward, the clamping plate 5 moves outward, and tightens the support frame 3, with the side template 2 pressed tightly against the side wall of the trench 1. After the work is completed, to disassemble, rotate the support sleeve 8 in the opposite direction to loosen the clamping plates 5 on both sides. Then remove the clamping plates 5 and take out the support frame 3 with welded side template 2.

[0024] Example 2, as Figures 1 to 7 As shown, based on Embodiment 1, the bottom of the positioning tip plate 6 is provided with a tip slope 601, which is inclined with the inner side higher than the outer side.

[0025] The bottom outer side of the positioning tip plate 6 is provided with a protective sleeve 602. When conveying and moving the support frame 3, the protective sleeve 602 is put on the bottom outer side of the positioning tip plate 6 for protection. When installing the support frame 3, the protective sleeve 602 can be removed.

[0026] The support sleeve 8 has nuts 9 fixed at both ends that mate with the support screw 10. The threads of the two nuts 9 are opposite in direction, and the threads of the support screw 10 at both ends are also opposite in direction. The support sleeve 8 has a rotating insertion hole 7 in the middle.

[0027] A reinforcing sleeve 12 is fixed inside the rotating insertion hole 7, running radially along the support sleeve 8. A rotating rod 14 is located inside the reinforcing sleeve 12. One end of the rotating rod 14 is fixed with a limiting boss 13, and the other end is threadedly connected to a limiting ball 15. To rotate the support sleeve 8, first insert the rotating rod 14 into the reinforcing sleeve 12, then screw on the limiting ball 15. This will rotate the rotating rod 14, causing the support sleeve 8 to rotate.

[0028] A pin 4 is fixed to the outer end of the support screw 10. An ear plate 11 is rotatably mounted on the pin 4 and fixed to the outer wall of the clamping plate 5. When the side of the groove 1 is... Figure 7 When the tilt setting is in place, the card plate 5 can be better adapted to the transverse stiffener 302 according to the side tilt angle and tilt angle of the groove 1.

[0029] The inner wall of the card plate 5 is provided with a clearance groove, and a limiting plate 18 is provided in the clearance groove. The outer wall of the transverse stiffener 302 is provided with a limiting groove that cooperates with the limiting plate 18. A guide hole is provided on the outer side of the clearance groove, and a pull rod 19 is provided in the guide hole. The inner end of the pull rod 19 is fixed to the limiting plate 18. A mounting sleeve 20 coaxial with it is fixed on the outer wall of the guide hole. A guide ring 16 is provided in the mounting sleeve 20. The guide ring 16 is fixed to the pull rod 19. A spring 17 is sleeved on the pull rod 19 outside the guide ring 16. The outer end of the spring 17 contacts the inner wall of the outer end of the mounting sleeve 20. The outer end of the pull rod 19 passes through the mounting sleeve 20 and fixes the limiting plate. When installing the clamping plate 5, first pull the limiting plate outward, thereby driving the pull rod 19 to move outward against the elastic force of the spring 17, so that the limiting plate 18 is retracted into the clearance groove. Then, clamp the clamping plate 5 on the outside of the transverse stiffener 302, and then release the limiting plate. Under the action of the spring 17, the limiting plate 18 will be clamped into the limiting groove for limiting.
