Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a clamping self-tightening edge operation safety suspension point device and a method of using the same. Background Art

[0002] During the construction of high-rise buildings, safety hazards are diverse, complex and random. Working on edges and at heights (such as secondary structure masonry, internal and external wall plastering, etc.) are all high-frequency hazard sources, so corresponding protective measures are required.

[0003] At present, after the scaffolding for edge and high-altitude operations is dismantled, it is not easy for on-site construction workers to find convenient and reliable safety hanging points, and they cannot get timely and effective protection when danger occurs. Without a reliable hanging point, the safety belt is useless. Based on this, the present application proposes a clamping self-tightening edge operation safety hanging point device and its use method. Summary of the invention

[0004] The present application provides a clamping self-tightening edge work safety hanging point device and a method of using the same, which can provide a firm and reliable safety belt hanging point by clamping it on a wall through a sliding wedge block, thereby providing safety protection for workers performing edge work and high-altitude work, ensuring the safety of the workers and improving safety.

[0005] In order to solve the above technical problems, this application adopts the following technical solutions: The first aspect of the present application provides a clamping self-tightening edge operation safety hanging point device, comprising a U-shaped plate, two sliding wedge blocks, two movable wedge blocks, two screw rods and a hanging ring. The U-shaped plate comprises a horizontal plate and two vertical plates, and the two vertical plates are arranged at two ends of the horizontal plate. The horizontal plate is provided with a sliding groove, and a spring is arranged in the sliding groove. The vertical plate is provided with a threaded hole, and the two sliding wedge blocks are symmetrically arranged at the two ends of the spring. A sliding block is provided at the bottom of the sliding wedge block, and the sliding block is slidably connected in the sliding groove, and the inclined surfaces of the two sliding wedge blocks deviate from each other. The two movable wedges are arranged one-to-one on the two sliding wedge blocks, and the inclined surfaces of the movable wedge blocks are in contact with the inclined surfaces of the sliding wedge blocks. The two screw rods are arranged one-to-one in the threaded holes, and the screw rods can abut against the vertical surfaces of the movable wedge blocks. The hanging ring is arranged on the lower surface of the horizontal plate.

[0006] When in use, clamp the two sliding wedges on both sides of the wall, then place the active wedge on the sliding wedges, and then adjust the screw rod so that the screw rod abuts against the active wedge, so that the sliding wedges are clamped on both sides of the wall, and finally hang the hook of the safety belt on the hanging ring. When the hook pulls the hanging ring downward, the entire U-shaped plate tends to move downward, so that the sliding wedges tightly clamp the wall under the action of the active wedge and the screw rod, and the static friction between the sliding wedge and the wall prevents the U-shaped plate from moving downward, thereby preventing the safety belt from moving downward, playing a protective role.

[0007] Compared with the existing technology, the clamping self-tightening edge work safety hanging point device is clamped on the wall through a sliding wedge block, and can provide a firm and reliable safety belt hanging point, provide safety protection for workers working on edges and at heights, ensure the safety of workers, and improve safety.

[0009] In one embodiment of the present application, the inclined surface of the sliding wedge block is provided with a limiting groove, and the inclined surface of the movable wedge block is provided with a limiting rib, and the limiting rib matches the limiting groove.

[0010] In one embodiment of the present application, a partition is provided in the middle of the slide groove, and the springs are provided on both sides of the partition, and the springs are respectively connected to the two sliding wedges.

[0011] In one embodiment of the present application, a handle is provided at the end of the screw rod.

[0012] In one embodiment of the present application, the slide groove is in an inverted T shape.

[0013] In one embodiment of the present application, the vertical plate is connected to the horizontal plate by bolts.

[0014] In one embodiment of the present application, the width of the vertical surface of the sliding wedge is 100 mm to 150 mm, and the height is 200 mm to 300 mm.

[0025] The embodiment of the first aspect of the present application provides a clamping self-tightening edge operation safety suspension point device, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a U-shaped plate 100, two sliding wedges 200, two movable wedges 300, two screw rods 400 and a hanging ring 500, wherein the U-shaped plate 100 is a structure for installing and supporting other components, the sliding wedges 200 are components for clamping the wall 010, the movable wedges 300 are components for pressing the sliding wedges 200, the screw rods 400 realize abutment against the movable wedges 300, and the hanging ring 500 provides a hanging position for the safety belt.

[0026] like Figure 1 As shown, the U-shaped plate 100 includes a horizontal plate 110 and two vertical plates 120, and the two vertical plates 120 are arranged at both ends of the horizontal plate 110 to form a U-shaped structure. The horizontal plate 110 is provided with a slide groove 111, and a spring 130 is arranged in the slide groove 111. The component connected to the spring 130 can slide in the slide groove 111. The vertical plate 120 is provided with a threaded hole 121 to provide a threaded connection structure.

[0027] like Figure 3 As shown, two sliding wedges 200 are symmetrically arranged at both ends of the spring 130, and a slider 210 is arranged at the bottom of the sliding wedge 200, and the slider 210 is slidably connected in the slide groove 111, so that the entire sliding wedge 200 can slide relative to the horizontal plate 110. The inclined surfaces of the two sliding wedges 200 are away from each other, that is, the inclined surfaces of the sliding wedges 200 face the corresponding vertical plates 120, that is, the inclined surfaces of the sliding wedges 200 face outward.

[0028] like Figure 3 As shown, two movable wedges 300 are arranged on two sliding wedges 200 in a one-to-one correspondence, and the inclined surfaces of the movable wedges 300 and the inclined surfaces of the sliding wedges 200 are in contact with each other, that is, the movable wedges 300 are buckled on the sliding wedges 200. When the movable wedges 300 are subjected to external force, the external force can be transmitted to the sliding wedges 200.

[0029] It should be noted that if Figure 4As shown in FIG. 5 , the sliding wedge 200 and the movable wedge 300 are both block structures with a substantially triangular cross section, and both have an inclined surface and a vertical surface.

[0030] like Figure 3 As shown, two screw rods 400 are arranged in the threaded hole 121 in a one-to-one correspondence. When the screw rods 400 rotate, the screw rods 400 can abut against the vertical surface of the movable wedge block 300, so that the movable wedge block 300 presses the sliding wedge block 200, and the sliding wedge block 200 tightly clamps the wall 010.

[0031] During implementation, a plurality of threaded holes 121 may be provided on each vertical plate 120 , so that a plurality of screw rods 400 may be provided to increase the abutting force on the movable wedge block 300 , thereby increasing the pressure of the sliding wedge block 200 on the wall 010 .

[0032] like Figure 3 As shown, the hanging ring 500 is arranged on the lower surface of the cross plate 110 to provide a hanging point for the safety belt.

[0033] When in use, two sliding wedges 200 are clamped on both sides of the wall 010, and then the movable wedge 300 is placed on the sliding wedge 200, and then the screw rod 400 is adjusted so that the screw rod 400 abuts against the movable wedge 300, so that the sliding wedge 200 is clamped on both sides of the wall 010, and finally the hook of the safety belt is hung on the hanging ring 500. When the hook pulls the hanging ring 500 downward, the entire U-shaped plate 100 tends to move downward, so that the sliding wedge 200 tightly clamps the wall 010 under the action of the movable wedge 300 and the screw rod 400, and the static friction between the sliding wedge 200 and the wall 010 prevents the U-shaped plate 100 from moving downward, thereby preventing the safety belt from moving downward, playing a protective role.

[0034] Compared with the prior art, the clamping self-tightening edge work safety hanging point device is clamped on the wall 010 by the sliding wedge block 200, and can provide a firm and reliable safety belt hanging point, provide safety protection for workers performing edge work and high-altitude work, ensure the safety of the workers, and improve safety.

[0035] In addition, the distance between the two sliding wedges 200 can be changed, so that the device can be applied to walls 010 of different thicknesses, thereby expanding the application range of the entire device.

[0036] In some embodiments, the vertical surface of the sliding wedge block 200 is provided with an anti-skid pad, which is in direct contact with the wall 010. The anti-skid pad has a high friction coefficient, which increases the static friction between the sliding wedge block 200 and the wall 010, making it more secure.

[0037] In some embodiments, Figure 4 and Figure 5As shown, the inclined surface of the sliding wedge block 200 is provided with a limiting groove 220, and the inclined surface of the movable wedge block 300 is provided with a limiting rib 310. The limiting rib 310 matches the limiting groove 220, so that the movable wedge block 300 and the sliding wedge block 200 are matched and positioned to avoid misalignment and movement of the movable wedge block 300.

[0038] In some embodiments, Figure 3 As shown, a partition 112 is provided in the middle of the slide groove 111, and the partition 112 provides an installation position for the spring 130 so that one end of the spring 130 remains fixed. Springs 130 are provided on both sides of the partition 112, and the springs 130 are respectively connected to two sliding wedges 200. When the spring 130 is stretched, the spring 130 has a rebound force, which can clamp the sliding wedge 200 on the wall 010.

[0039] In some embodiments, Figure 1 As shown, a handle 410 is provided at the end of the screw rod 400, and the operator can conveniently rotate the screw rod 400 through the handle 410 to realize the rotation of the screw rod 400 without the aid of other tools, which is convenient for use at the construction site.

[0040] In some embodiments, the slide groove 111 is in an inverted T-shape, and the sliding block 210 is also in an inverted T-shape accordingly, which can prevent the sliding wedge block 200 from detaching from the cross plate 110 .

[0041] In some embodiments, Figure 6 As shown, the vertical plate 120 is connected to the horizontal plate 110 by bolts. In this way, the horizontal plate 110 and the vertical plate 120 are detachable. When the entire device is assembled for the first time, the slider 210 on the sliding wedge 200 can slide from one end of the horizontal plate 110 into the slide groove 111 to achieve the sliding connection between the two, and then the vertical plate 120 and the horizontal plate 110 can be installed together. Through this structure, it is convenient to achieve the sliding connection between the sliding wedge 200 and the horizontal plate 110. In the subsequent use process, the sliding wedge 200 remains sliding in the slide groove 111, and does not need to be disassembled, which is also convenient for the next use.

[0042] In some embodiments, the width of the vertical surface of the sliding wedge block 200 is 100 mm to 150 mm, and the height is 200 mm to 300 mm, so as to ensure that the sliding wedge block 200 and the wall 010 have a sufficiently large contact area to ensure the friction between the two.

[0043] The second aspect of the present application provides a method for using the clamping self-tightening edge operation safety suspension point device of the first aspect, such as Figure 7 As shown, the following steps are included: S1: The operator applies force with both hands to open the two sliding wedges 200, and places the two sliding wedges 200 on both sides of the wall 010 respectively. After removing the external force, the two sliding wedges 200 are clamped on the wall 010 under the action of the spring 130, and the entire device is clamped and placed. At this time, the sliding wedges 200 are only clamped on the wall 010 by the rebound force of the spring 130, which is convenient for installing the entire device, and the operator does not need to support or hold the entire device.

[0044] S2: Place the inclined surfaces of the two movable wedge blocks 300 one by one on the inclined surfaces of the two sliding wedge blocks 200. The movable wedge blocks 300 press on the sliding wedge blocks 200 to transmit the force.

[0045] S3: Rotate the two screw rods 400 so that the screw rods 400 gradually approach the vertical surface of the movable wedge block 300 until the screw rods 400 abut against the vertical surface of the movable wedge block 300, so that the movable wedge block 300 is tightly buckled on the sliding wedge block 200, so that the sliding wedge block 200 can be tightly clamped on the wall 010, and the entire device is fixed on the wall 010.

[0046] S4: The operator hangs the hook of the safety belt on the hanging ring 500 to protect the operator himself and improve safety.

[0047] Compared with the prior art, this method of use can provide a firm and reliable safety belt hanging point by clamping the sliding wedge block 200 on the wall 010, provide safety protection for workers working on edges and at heights, ensure the safety of the workers, and improve safety.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
