Description

Technical Field

[0001] This application relates to the technical field of fall protection devices in construction, and in particular to an auxiliary device for fall protection in construction. Background Technology

[0002] In high-rise building construction, workers must wear safety belts when working near edges or around pre-reserved openings to reduce the risk of falls. However, in some building construction projects, there is a lack of designated locations for attaching safety belts. Therefore, it is often necessary to drill holes in the walls or ground and install lifting rings or similar devices to secure the safety belts.

[0003] Although it is possible to fix the lifting rings to connect the safety belt through later construction, it requires damaging the building structure. After the lifting rings are removed, the damaged areas need to be repaired, which is quite troublesome. Utility Model Content

[0010] Optionally, the connecting plate is provided with an extension tube, the crossbar is slidably inserted into the extension tube, and the locking member is used to connect the crossbar and the extension tube together to restrict the crossbar from sliding in the extension tube.

[0011] By adopting the above technical solution, the crossbar is slidably inserted into the extension cylinder, thereby adjusting the space between the two clamping parts and positioning it by the locking element, so that the crossbar can no longer slide.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a construction safety fall prevention auxiliary device. (Refer to...) Figure 1 The auxiliary device is mainly installed in the door of the building unit. For example, when it is necessary to carry out work near the edge, such as on a balcony, the construction worker connects one end of the safety belt to the auxiliary device, which provides the connection point of the safety belt.

[0035] Reference Figure 2 and Figure 3 The auxiliary device includes a crossbar 1 and clamping parts 2 installed at both ends of the crossbar 1. The distance between the two clamping parts 2 can be adjusted to better adapt to the width of the door. A locking member 3 is installed between the clamping parts 2 and the crossbar 1 to position the clamping parts 2, thus preventing the clamping parts 2 and the crossbar 1 from sliding relative to each other. A clamping space 4 is formed at the end of the clamping part 2 opposite to the crossbar 1. The size of the clamping space 4 can be adjusted so that the clamping part 2 can be clamped to the wall of the door, thus preventing the clamping part 2 from shaking.

[0036] The clamping part 2 includes a connecting plate 21, a fixing plate 22 fixedly mounted on the connecting plate 21, and an adjusting plate 23 slidably mounted on the connecting plate 21. A clamping space 4 is formed between the fixing plate 22 and the adjusting plate 23. The fixing plate 22 and the adjusting plate 23 are mounted on the side of the connecting plate 21 opposite to the crossbar 1, and the fixing plate 22 and the adjusting plate 23 are perpendicular to the surface of the connecting plate 21. A positioning element 5 is installed on the adjusting plate 23 for positioning the adjusting plate 23. After the distance between the adjusting plate 23 and the fixing plate 22 is adjusted, the adjusting plate 23 is positioned by the positioning element 5. A reinforcing rib 14 is fixed between the fixing plate 22 and the connecting plate 21. The reinforcing rib 14 is located on the side of the fixing plate 22 opposite to the clamping space 4, and the reinforcing rib 14 improves the connection strength between the fixing plate 22 and the connecting plate 21.

[0037] An extension cylinder 6 is fixed on the side of the connecting plate 21 opposite to the adjusting plate 23, and the extension cylinder 6 is located at the center of the connecting plate 21. One end of the crossbar 1 is slidably inserted into the extension cylinder 6, and the crossbar 1 is positioned by the locking member 3 to limit the sliding of the crossbar 1. Therefore, the distance between the two clamping parts 2 can be adjusted by adjusting the distance of the crossbar 1 inserted into the extension cylinder 6.

[0038] Reference Figure 2 and Figure 3The locking element 3 includes an abutment ring 31 threadedly connected to the outer wall of the crossbar 1 and a threaded cylinder 32 slidably disposed on the outer wall of the crossbar 1. The opening of the threaded cylinder 32 faces the adjacent extension cylinder 6. The position of the abutment ring 31 can be adjusted by rotating it. When the crossbar 1 is inserted into the extension cylinder 6, the abutment ring 31 abuts against the end face of the extension cylinder 6, and then the threaded cylinder 32 is threadedly connected to the outer wall of the extension cylinder 6, so that the abutment ring 31 can be pressed between the end face of the extension cylinder 6 and the inner end face of the threaded cylinder 32.

[0039] The positioning component 5 includes two extension posts 51 fixed to one side edge of the adjusting plate 23, and a retaining block 52 threadedly connected to the extension posts 51. The two extension posts 51 are distributed vertically. The connecting plate 21 has sliding grooves 15 for the extension posts 51 to slide, and the sliding grooves 15 correspond one-to-one with the extension posts 51. The retaining block 52 can abut against the surface of the connecting plate 21, thereby fixing the adjusting plate 23 to the connecting plate 21. Furthermore, in order to improve the positioning effect of the adjusting plate 23, a reinforcing member 8 is installed on the extension cylinder 6. The reinforcing member 8 is used to connect with the two retaining blocks 52 to restrict the sliding or rotation of the retaining blocks 52.

[0040] The reinforcing component 8 includes a reinforcing base 81 and a bolt 82 that passes through the reinforcing base 81 and is threaded onto the extension cylinder 6. One end of the bolt 82 can be pressed against the fixed base. Both ends of the fixed base are provided with positioning grooves 7. The pressing block 52 has a polygonal structure, and the structure of the positioning grooves 7 is adapted to the pressing block 52. After the pressing block 52 is engaged in the positioning grooves 7, it is less likely to rotate under the action of the reinforcing base 81. To improve the pressing effect of the pressing block 52, a gasket can be fitted onto the outer wall of the extension column 51. The pressing block 52 presses against the gasket, which also facilitates adjusting the pressing block 52 to a position where it can be engaged in the positioning grooves 7.

[0041] Furthermore, refer to Figure 3 and Figure 4 A positioning pin 9 is threaded onto the connecting plate 21. Two positioning pins 9 are provided and are located on the upper and lower sides of the extension cylinder 6, respectively. In use, one end of the positioning pin 9 can abut against the inner wall of the door body, thereby better positioning the clamping part 2. A sliding ring 10 is slidably sleeved on the outer wall of the end of the positioning pin 9 extending into the clamping space 4. An oblong groove 11 is opened on the adjusting plate 23. A through rod 12 is fixed on the sliding ring 10. The through rod 12 passes through the oblong groove 11 and is threadedly connected to a nut 13. The nut 13 abuts against the side of the adjusting plate 23 away from the clamping space 4. Under the action of the through rod 12, the adjusting plate 23 and the positioning pin 9 are connected together, thereby providing multi-point support and connection for the adjusting plate 23, and further improving the stability of the adjusting plate 23.

[0042] The implementation principle of the construction safety fall prevention auxiliary device in this application embodiment is as follows: by adjusting the position of the clamping part, the clamping part 2 is clamped on the walls on both sides of the door body, and the clamping part 2 and the crossbar 1 are positioned by the locking part 3; then the through rod 12 and the adjusting plate 23 are connected together, and the safety belt can be tied to the crossbar 1.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
