[0021] The following will be combined with the accompanying drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. The present embodiment described herein is only for illustrative purposes and is not intended to limit the scope of protection of the present invention. Therefore, it should be understood that various modifications and changes can be made to this embodiment without departing from the scope of protection of the present invention.

[0022] In the description of the present invention, unless otherwise clearly specified and limited, the term "and / or" includes any and all combinations of one or more associated listed items. Unless otherwise specified or explained, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, an electrical connection, or a signal connection; "connection" can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Further, in the description of the present invention, it should be understood that the directional words described in the present embodiment are described at the angles shown in the accompanying drawings and should not be understood as limiting the present embodiment. It should also be understood that in the context, when it is mentioned that an element or feature is connected to another element (one or more), it can not only be directly connected to the other (one or more) elements, but also indirectly connected to the other (one or more) elements through an intermediate element.

[0024] Before introducing the technical solution of the present invention, it is necessary to explain the background of the invention. It is common that when performing aerial work at a height of more than two meters in some narrow spaces, due to the complex environment of the narrow space or the fact that the top of the narrow space can no longer be destroyed, and there is no pre-buried safety rope buckle, the narrow space cannot provide support for the operator's safety belt hanging. For this reason, a safety belt hanging rack that can provide a hanging point for the safety belt has become the best choice for aerial work in the above-mentioned narrow space, but the existing safety belt hanging racks generally have the following technical defects: 1. The base structure of the safety belt hanging rack is simple and only provides simple support, and the safety belt hanging rack as a whole is at risk of overturning; 2. The overall size of the safety belt hanging rack is too large, which makes it difficult to carry it into a narrow space. In order to overcome the technical problems of the above-mentioned prior art, the present invention aims to provide a safety belt hanging rack for high-altitude work in a small space.

[0025] See also Figure 1 to Figure 2An exemplary embodiment of the present invention provides a safety belt suspension frame for high-altitude operations in a small space, comprising two groups of suspension single frames, each group of suspension single frames comprising a first vertical pole 1, a second vertical pole 2 slidably mounted inside the first vertical pole 1, and a support assembly for supporting the first vertical pole 1, wherein the support assembly comprises a first fixing member 31 capable of sliding on the surface of the first vertical pole 1, and a second fixing member 34 fixed to the bottom of the first vertical pole 1, three groups of diagonal support rods 32 are hinged on the outer edge of the first fixing member 31, and three groups of limiting rods 33 are hinged on the second fixing member 34. A guide rail is provided on the side of any diagonal support rod 32, and a slider that can be mounted in the guide rail is provided at the end of any limiting rod 33. When the first fixing member 31 slides toward the second fixing member 34, the diagonal support rod 32 will be driven to prop up outward, and when the slider slides to the end of the guide rail, the diagonal support rod 32 is locked by a locking member. It should be noted that this single suspension frame has two states: folded and unfolded. In the folded state, the second upright pole 2 is completely located inside the first upright pole 1 and the support assembly fits the first upright pole 1. In the unfolded state, the second upright pole 2 extends from the inside of the first upright pole 1 and the support assembly is propped up to reinforce the first upright pole 1.

[0026] Furthermore, to ensure that the support assembly does not move when the single hanging frame is in the folded state, in some embodiments, the first vertical pole 1 is provided with a spring lock tongue, and the first fixing member 31 is provided with a receiving cavity equipped with a pressing plate. When the first fixing member 31 slides away from the second fixing member 34, the support assembly will be folded, and the spring lock tongue will shrink into the receiving cavity to lock the first fixing member 31, wherein pressing the pressing plate can unlock the first fixing member 31. When working in a construction environment where the top and the wall cannot provide support, the construction personnel will carry the single hanging frame to the designated position in the folded state, and then extend the second vertical pole 2 from the first vertical pole 1, and press the pressing plate to unlock the first fixing member 31, and the first fixing member 31 will slide down to make the diagonal support rod 32 prop up outward for support.

[0027] Furthermore, in order to ensure that the diagonal brace rod 32 does not move when used for support, in some embodiments, the end of the guide rail of the first vertical pole 1 is provided with a first screw hole, the slider is provided with a second screw hole, and the locking member is a connecting bolt. When the slider slides to the end of the slide rail, the first screw hole and the second screw hole are connected by the connecting bolt to achieve the fixation of the diagonal brace rod 32 and the limit rod 33, so that the diagonal brace rod 32 can remain stable, that is, maintain the overall stability of the support assembly when it is deployed. Preferably, in some embodiments, when the diagonal brace rod 32 is locked, the angle between the diagonal brace rod 32 and the ground is 45°-60°. The angle within this range can effectively disperse and bear the load from above the first vertical pole 1, avoiding insufficient support force or structural instability caused by too large or too small an angle.

[0028] See also Figure 1 to Figure 2On the basis of the above-mentioned structure of the suspension single frame, the safety belt suspension frame includes a steel cable 4. A pulley base 35 with a fixed pulley is provided on the top of the second vertical pole 2 of one group of the suspension single frames, and a steel cable fixing buckle 36 is provided on the top of the second vertical pole 2 of another group of the suspension single frames. The steel cable 4 passes through the pulley and is fixed in the steel cable fixing buckle 36. The construction workers extend the safety belt buckle into the above-mentioned steel cable 4 and cooperate with the construction ladder to safely work in a construction environment where the top and wall cannot provide support.

[0029] Preferably, in order to reduce the friction when the first fixing member 31 slides, in some embodiments, the middle part of the first fixing member 31 is configured as a clamp structure with a bolt hole, wherein when the clamp structure is unlocked, the first fixing member 31 and the first vertical pole 1 are in clearance fit to reduce the friction when the first fixing member 31 slides; when the clamp structure is tightened, the first fixing member 31 and the first vertical pole 1 fit tightly to make the support assembly evenly stressed, avoiding the safety hazard of multiple groups of diagonal braces 32 in the support assembly being deformed and damaged due to excessive extrusion due to uneven stress. It should be noted that the three groups of diagonal braces 32 are distributed at 120° intervals to be hinged to the outer edge of the first fixing member 31.

[0030] Furthermore, in some embodiments, the bottom of the diagonal support rod 32 and the bottom of the first vertical rod 1 are both provided with an anti-slip sleeve 321. The anti-slip sleeve 321 can increase the friction between the diagonal support rod 32 and the ground, so as to effectively prevent sliding between the diagonal support rod 32 and the ground, thereby significantly enhancing the supporting effect of the supporting assembly.

[0031] As a preferred technical solution, in some embodiments, the outer walls of the first vertical pole 1 and the second vertical pole 2 are provided with a ruler so that construction personnel can flexibly adjust the height of the single suspension frame according to the construction environment. It should be noted that the height between the first vertical pole 1 and the second vertical pole 2 can be manually adjusted and then locked by a locking member to fix the height, or an electric lift can be provided between the first vertical pole 1 and the second vertical pole 2 to achieve a telescopic effect. It should be noted that in some embodiments, the first vertical pole 1, the second vertical pole 2 and the support assembly are all made of high-strength steel, which not only ensures the lightweight of the safety belt suspension frame of the present invention, but also ensures its anti-impact safety, and increases the strength of the materials of the first vertical pole 1, the second vertical pole 2 and the components of the support assembly.

[0032] In summary, the seat belt suspension frame adopting the above structure has the following technical advantages:

[0033] 1. The present invention is applicable to construction environments where the top and walls cannot provide support, and has achieved the effect of being applicable to most construction environments. A supporting component is set at the bottom of the first vertical pole to enhance the stability of the single suspension frame, so as to effectively prevent the overall overturning of the safety belt suspension frame. 2. The present invention adopts a retractable structure, and the second vertical pole can be retracted inside the first vertical pole, which is convenient for the transportation of the entire safety belt suspension frame, and solves the problems of equipment entry and equipment portability in complex construction environments. At the same time, its retractable structure can achieve the effect of being able to be flexibly adjusted according to the construction environment. Therefore, compared with the existing safety belt suspension technology, the safety belt suspension frame for high-altitude operations in small spaces provided by the present invention has obvious technical advantages.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
