Technical Field

[0001] The invention relates to the technical field of construction tools, in particular to a clamp used for hanging and fixing a safety belt for edge operations. Background Art

[0002] There are a large number of danger sources at the construction site of a building project. There are endless incidents of construction workers falling from high places while working near edges. Especially in confined spaces such as high-rise buildings, super-high-rise buildings, and pools, it is difficult to fully hang safety belts. Construction workers neglect safety awareness near edges and do not hang safety belts out of the hope of getting away with it, which can easily lead to accidents.

[0003] To address this issue, construction workers used scrap materials from the site to create a simple clamp for hanging the safety belt. This clamp, fixed to the structural column, is U-shaped, with screws running through the two arms of the U. A pressure plate is welded to the inside of the screws. By tightening the screws, the clamp is secured to the column via the pressure plate, and the safety belt is then fastened to the clamp. While this simple clamp provides some safety protection, it is not securely attached to the column and can easily slip or even become detached, posing a significant safety risk.

[0019] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The following embodiments may be understood as explaining a local structure of the present invention individually, or may be understood as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0021] A clamp for hanging and fixing a safety belt for edge work, such as Figure 1 、 2 As shown, it includes a U-shaped frame, and the two arm ends of the U-shaped frame are provided with threaded sections 207. The threaded sections 207 are equipped with safety rods 209. Through holes are provided at both ends of the safety rod 209. The two through holes are sleeved on the corresponding threaded sections 207. The threaded sections 207 outside the through holes are screwed with limit nuts 210 for limiting the position of the safety rod 209. The U-shaped frame is also equipped with multiple anti-fall splints.

[0022] Further, such as Figure 1 、 2 As shown, the U-shaped frame includes two L-shaped rods 201 arranged opposite to each other, one arm of the two L-shaped rods 201 is parallel to each other, and the other arm is coaxially opposite to each other. The coaxially opposite arms are provided with sliding holes, and the two opposite sliding holes are slidably connected to a connecting rod 202. The outer surface of the connecting rod 202 is evenly distributed along the axial direction with a plurality of positioning blind holes (such as Figure 1 As shown, not marked in the figure), the outer wall of the sliding hole is provided with a threaded hole (such as Figure 1 As shown, not marked in the figure), the sliding hole and the connecting rod 202 are fixedly connected by a positioning bolt 212 that passes through the threaded hole and is inserted into the positioning blind hole. That is, the U-shaped frame is retractable and can be adapted to be fixed to structural columns of different sizes.

[0023] Further, such as Figure 1 、 2 As shown, the outer surface of the connecting rod 202 is rotatably connected to a sleeve 203, and the outer wall of the sleeve 203 is welded with a hanging ring 204 for connecting a safety belt.

[0024] Further, such as Figure 1 、 2 As shown, the anti-fall cleat includes a first cleat 211 integrally formed at the bottom of the outer wall of the sleeve 203. The first cleat 211 forms a 90° angle with the hanging ring 204. When the safety belt is connected, the weight of the person is transferred to the hanging ring through the safety belt, which in turn drives the sleeve to rotate, thereby clamping the first cleat against the surface of the structural column.

[0025] Further, such as Figure 1 、 2 As shown, the anti-fall splint also includes a second splint 208 which is arranged on the L-shaped rod arms parallel to each other and hinged to the rod arms. The hinge axes of the two second splints 208 are parallel to the L-shaped rod arms parallel to each other, and a telescopic mechanism 206 is connected between the upper part of the inner surface of the second splint 208 and the top of the corresponding rod arm.

[0026] like Figure 1 、 2 As shown, the telescopic mechanism 206 includes a sleeve 2061, a first threaded rod 2063, and a second threaded rod 2062. The inner surface of the sleeve 2061 is provided with internal threads of opposite rotation at both ends. The opposing ends of the first threaded rod 2063 and the second threaded rod 2062 are respectively threadedly connected to the inner surface of the sleeve 2061. Rotating the sleeve 2061 causes the first threaded rod 2063 and the second threaded rod 2062 to simultaneously move toward or away from the sleeve 2061. The outer ends of the first threaded rod 2063 and the second threaded rod 2062 are respectively hinged to the inner surface of the second clamping plate 208 and the top of the corresponding arm. As can be understood from the structure, when the clamp is in use, the weight of the human body pulls the U-shaped frame downward, and the end of the second clamping plate tightly contacts the surface of the structural column, causing the second clamping plate to rotate further toward the structural column surface, thereby increasing the pressure applied by the second clamping plate on the structural column surface, thereby making the clamp more secure.

[0027] like Figure 1 As shown, the outer surface of the lever arm where the outer side of the second clamping plate 208 is located is provided with a threaded section.

[0028] The working principle of this new model:

[0029] When in use, first adjust the width of the U-shaped frame according to the size of the structural column and fix it with positioning bolts, then put the U-shaped frame on the structural column so that the first clamping plate can contact the surface of the structural column when rotating inward, rotate the sleeve to extend the telescopic mechanism, clamp the second clamping plate to the surface of the structural column, then put on the safety rod, tighten the limit nut, connect the safety rope to the hanging ring, and then you can carry out edge work.
