Description

Technical Field

[0001] The utility model relates to the field of foundation pit protection devices, in particular to a protection device used for foundation pits. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. The foundation pit is a temporary project. Its function is to provide a space so that the foundation masonry work can be carried out according to the position specified in the design. The amount and size of each foundation pit are different. When carrying out foundation pit operations, in addition to the protection inside the pit, interception protection is also required outside the pit to prevent strangers from entering. The existing external protection is basically intercepted by assembled protective guardrails. The length of the protective guardrail cannot be adjusted and the whole cannot be retracted. It occupies a large volume and is inconvenient to transport and move. At the same time, in order to achieve comprehensive protection, the small beams of the guardrail must be designed to be more dense, which also increases its own weight and has low flexibility.

[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1-Figure 4 As shown, a protection device for foundation pits is composed of a protection rope box group 7, a plurality of vertical frames 1, and a prismatic scissor frame 3 matching the number of vertical frames 1;

[0019] A set of grippers 11 is installed on the stand 1, and each stand 1 is provided with two sets of grippers 11. The two ends of the prismatic scissor frame 3 are mounted on the set of grippers 11 through clamp sleeves 13 to achieve assembly. A movable fixed frame is installed at the bottom of the stand 1;

[0020] The protective rope box group 7 is installed on any one of the vertical frames 1. The number of protective rope box groups 7 is set according to actual use requirements. The protective rope box group 7 consists of a wheel box 71 and a take-up wheel installed in the wheel box 71 through a wheel axle. A protective rope 74 is wound around the take-up wheel. A wire outlet hole is opened on the side box wall of the wheel box 71. One end of the protective rope 74 extends to the outside of the wheel box 71 through the wire outlet hole and is connected to a rope hook 75. A box side rope hanger 76 is fixedly installed on the outer box wall of the wheel box 71. The box side rope hanger 76 is used to hang with the rope hook 75, so as to facilitate the protective winding of the area enclosed by the vertical frame 1 and the prismatic scissor frame 3;

[0021] An open clamping sleeve 72 is fixedly installed on the outer hole edge of the wire outlet hole, and a spin-pressing sleeve 73 is screwed on the open clamping sleeve 72. The spin-pressing sleeve 73 clamps the protective rope 74 by rotating the open clamping sleeve 72 to fix it. The open clamping sleeve 72 is a currently commonly used spin-pressing sleeve component, and its opening is tightened by spinning to clamp the inside.

[0022] like Figure 1-Figure 4 As shown, the utility model also discloses the following more optimized specific structures:

[0023] The movable fixed frame assembly is composed of a movable frame 2 and a fixed ear 5 installed on the side of the movable frame 2, a spiral ground nail 6 is inserted into the fixed ear 5, and a caster 4 is installed at the bottom of the movable frame 2.

[0024] A box hanger 17 is fixedly installed on the stand 1, and a hanging groove is provided on the back side of the wheel box 71. The box hanger 17 is hung in the hanging groove to achieve the installation of the wheel box 71. One end of the wheel axle extends to the outside of the wheel box 71 and is installed with a swivel 77. The swivel 77 is a hexagonal swivel for easy wire winding.

[0025] The prism-shaped scissor frame 3 is composed of four edge arms 31 and arm end hinged parts 32 hinged at the end sides of the edge arms 31.

[0026] A gripper sleeve 12 is sleeved on the gripper 11, and the clamp sleeve 13 is composed of two semi-arc bodies 14. One end of the two semi-arc bodies 14 is hinged together, and the other end of the two semi-arc bodies 14 is installed with a clamp sleeve ear 16, and the clamp sleeve ear 16 is installed with a clamp sleeve bolt 15 for easy assembly.

[0027] like Figure 1-Figure 4When in use, the protective device for foundation pits shown in the figure is assembled with several vertical frames 1 and prismatic scissor frames 3 according to the side length of the foundation pit, and then they are enclosed by stretching to form a protective circle. The prismatic scissor frames 3 can increase their length by stretching, and then are fixed by spiral ground nails 6. Since the upper and lower spans of the stretched prismatic scissor frames 3 are narrow and the interception effect is poor, the protective rope box group is hung on any vertical frame 1 according to needs, and then the protective rope 74 is pulled out and wrapped around the enclosed frame body and then hooked to the box side rope hanger 76, and the rotary pressing sleeve 73 is tightened to provide better interception and protection. When disassembling, the protective rope 74 is rolled up and then folded and moved.

[0028] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
