Description

Technical Field

[0001] The invention relates to the technical field of construction safety, and in particular to a safety belt hanging point device capable of rotating 360 degrees. Background Art

[0002] With the rapid development of the construction industry, construction safety belts are also constantly developing and improving. The safety belt hanging point is an important device to ensure the safety of workers. It provides a stable hanging point for the safety belt to ensure that the safety belt can play an effective role in the event of accidents such as falling or tipping, reducing personal injuries.

[0003] Traditional safety belt tie-off point designs are often based on fixed structures and principles, and may not be able to adapt to workers in different working environments. At the same time, traditional safety belt tie-off points are usually fixed in a certain position, which restricts the movement of workers within a certain range. During the operation of workers, the safety belts connected to the buckles may be seriously entangled, affecting their work efficiency and safety. In order to ensure the safety of construction, the design and selection of tie-off points are crucial. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a 360° rotatable safety belt hanging point device, comprising a hollow metal piece, a vertical rod is inserted in the middle of the hollow metal piece, and a circular ring is fixedly connected to the upper end of the vertical rod. When in use, the hollow metal piece needs to be fixed or inserted in the vertical rod, and the length of the hollow metal piece and the vertical rod is long enough to avoid being pulled out when subjected to an oblique upward force. When in use, the hook can be sleeved in the circular ring.

[0005] Furthermore, a protrusion or a rough surface is provided on the lower side wall of the hollow metal part. When the hollow metal part is subjected to an oblique upward force and the upper part of the hollow metal part is deflected, the protrusion or the rough surface at the lower part fits with the inner wall of the column, thereby increasing friction and reducing the risk of the hollow metal part being pulled out.

[0006] Preferably, the lower part of the vertical rod is threadedly connected with a lower nut, the upper part of the vertical rod is threadedly connected with an upper nut, and the hollow metal piece is located between the lower nut and the upper nut. The lower nut and the upper nut are used to restrict the vertical rod on the hollow metal piece to prevent it from falling off.

[0007] Preferably, the device further comprises a spigot and a crossbar, wherein the spigot is fixedly connected to the upper side wall of the hollow metal member, the two ends of the crossbar are bent 90 degrees in the same direction, and the end of the crossbar fits in the spigot. When the operator moves, the crossbar can increase the range of movement.

[0008] Preferably, the number of the bell-and-spigot pipe is at least one. After the bell-and-spigot pipe is arranged, its lower end can be supported on the upper end of the vertical pole to provide support for the entire device. Preferably, two bell-and-spigot pipes are arranged to ensure that the hollow metal piece supported is balanced in force.

[0009] The beneficial effects of the present invention are as follows:

[0010] 1. Hollow metal parts, vertical rods, rings, etc. are provided. When working, the buckle is put on the ring. Since the ring can rotate relative to the hollow metal part, the safety belt connected to the buckle is avoided from being seriously entangled, and the working space is increased and the working efficiency and safety are improved.

[0011] 2. Two adjacent hollow metal parts can be connected with a cross bar, and the hook can also be transferred to the cross bar. During this period, the operator can move safely between two adjacent hollow metal parts, and can also work in the cross bar area, which greatly increases the scope of operation.

[0017] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Example

[0018] like Figure 1 As shown, a 360° rotatable safety belt hanging point device includes a hollow metal part 3, which is a tubular part and has a sufficiently long length, preferably set to 60 cm, with a hole diameter of 15 mm. A vertical rod 1 is inserted in the middle of the hollow metal part 3, and the vertical rod 1 is slightly longer than the hollow metal part 3. A circular ring 6 is fixedly connected to the upper end of the vertical rod 1, and the circular ring 6 is a connecting part of the hook 8. The diameter of the circular ring 6 is 10 cm.

[0019] When in use, the hollow metal part 3 is fixed or plugged into the upper end of the vertical pole 7. During construction, the operator binds and connects the hook 8 to the ring 6. Since the ring 6 can rotate with the vertical pole 1, the rope connected to the hook 8 can be avoided from being entangled, thereby improving construction efficiency.

[0020] The lower part of the vertical rod 1 is threadedly connected with a lower nut 2, the upper part of the vertical rod 1 is threadedly connected with an upper nut 5, and the hollow metal part 3 is located between the lower nut 2 and the upper nut 5, that is, threads are provided on the upper and lower side walls of the vertical rod 1. In order to achieve the cooperation of the upper nut 5, a boss can be optionally provided on the side wall of the vertical rod 1, and the side wall of the boss with threads, the upper nut 5 passes over the lower boss and is threadedly connected with the upper boss, that is, the inner diameter of the thread of the upper nut 5 is not less than the inner diameter of the lower nut 2, and the upper nut 5 and the lower nut 2 are used to limit the vertical rod 1 on the hollow metal part 3.

[0021] The device is used as follows: Figure 2 As shown, if there is a structure similar to the vertical rod 7 within the working range, the device can be directly plugged into the upper end of the vertical rod 7. If not, it is necessary to install the vertical rod within the construction range to ensure that the device can be stably fixed. Then the operator can put the connected buckle 7 on the ring 8 to ensure the safety of the construction workers. Example

[0022] This embodiment is based on the first embodiment, and has the following differences: Figure 1 and Figure 3 As shown, the device also includes a bell-and-spigot pipe 4 and a cross bar 9. The bell-and-spigot pipe 4 is fixedly connected to the upper side wall of the hollow metal part 3, and the bell-and-spigot pipe 4 is fixed by welding. Both ends of the cross bar 9 are bent 90° in the same direction, and the end of the cross bar 9 is fitted in the bell-and-spigot pipe 4. That is, the usage of this embodiment is as follows: when the operator is working or moving between two adjacent devices, the hook 8 needs to be sleeved on the cross bar 9 to increase the construction range of the operator.

[0023] Furthermore, through holes are provided on the side walls of the socket pipe 4 and the cross bar 9, and latches are inserted through the through holes to prevent the cross bar 9 from being pulled out due to an upward force.

[0024] Furthermore, in the actual construction process, since the distance between two adjacent devices is determined according to the working scenario, the distance between two adjacent devices cannot be guaranteed to be exactly equal to the length of the cross bar 9. Here, the cross bar 9 is divided into two sections, and the sections are connected in a mutually socketed manner, that is, one of them can extend to the inside of the other, and then fixed by means such as pins and nuts, so that the cross bar 9 can be adjusted according to the distance between the adjacent devices.

[0025] The number of the bell-and-spigot pipe 4 is at least one, and the lower end of the bell-and-spigot pipe 4 is pressed against the upper end of the vertical pole 7. In order to ensure the force balance of the bell-and-spigot pipe 4, it is best to symmetrically arrange two bell-and-spigot pipes 4 on the side wall of the vertical pole 1. Of course, in the actual operation process, if multiple cross bars 9 need to be connected, multiple bell-and-spigot pipes 4 can be welded.

[0026] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
