Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of safety protection, and specifically relates to a slope edge operation safety protection equipment. BACKGROUND

[0002] In order to avoid safety accidents of an operator when the operator works on a steep slope, safety protection equipment needs to be used to protect the operator. However, according to the working position usually located at the edge of the slope, an ideal and reliable safety rope suspension point cannot be easily found. The safety rope does not have an effective suspension point, or the suspension point is far away and not firm, which cannot effectively protect the operator and has great safety hazards.

[0003] For example, a Chinese utility model patent with the application number CN214435947U and the name of a safety belt suspension device for edge operation, which comprises a suspension steel pipe horizontally arranged on one end surface of a slope edge hole wall column, a clamp sleeve arranged at both ends of the suspension steel pipe, a clamp vertically arranged on the clamp sleeve and perpendicular to the axis of the clamp sleeve, a free end of the clamp being clamped on the other end surface of the slope edge hole wall column, a movable safety belt sleeve arranged on the suspension steel pipe, a safety belt buckle arranged on the safety belt sleeve, and a safety belt arranged on the safety belt buckle.

[0004] The above-mentioned prior art can protect the operator to a certain extent, but has the following disadvantages:

[0005] 1. The safety belt sleeve moves on the suspension steel pipe and cannot be fixed. When the slope edge hole wall column is in a low-high shape, the suspension steel pipe is in an inclined shape, and the safety belt sleeve will often be at the intersection of the suspension steel pipe and the low wall column, and cannot be protected most effectively at all times following the working position of the operator.

[0006] 2. The operator cannot select a suitable fixed point according to the working position. The farther the fixed point is from the operator, the worse the safety protection performance is. When the fixed point is far away from the operator, the safety rope is also long, which can be easily broken by friction with the slope, and the hidden danger of the safety rope is not easy to be found. When the fixed point is close to the operator, the state of the safety rope can be intuitively found and observed in real time by the operator, and the force arm is short, the force is strong, and the force is strong.

[0007] Therefore, how to ensure that the safety rope fixed point can move and be fixed with the operator so that the safety protection equipment can play the maximum safety protection is a problem to be solved. SUMMARY

[0085] The working principle of the present application is as follows:

[0086] 1. First, fix the second safety support 2 and the first safety support 1 on the slope top in a desirable and reliable position to ensure stability.

[0087] 2. Connect the second safety support 2 and the first safety support 1 through the anti-detachment mechanism.

[0088] 3. When the operator is preparing for work, connect the safety rope 6 on the operator with the safety rope fixing part 5, and as the operation range of the operator changes, the mobile sleeve 3 can move on the horizontal rod one 11 to avoid limiting the operation range of the operator.

[0089] 4. When the operator's working position needs to be changed, press down the handle 43 to make the limiting part 46 disengage from the limiting hole 23, and then move the moving sleeve 41 on the crossbar 11 according to the operator's working position.

[0090] 5. When the movable sleeve 41 is moved to the appropriate position, pull the handle 43 up to insert the limiting piece 46 into the corresponding limiting hole 23, thereby fixing the position of the movable sleeve 41. This can reliably and stably protect the safety of the workers without restricting their movement range on the slope.

[0091] 6. At the same time, the second movable sleeve 31 on the anti-detachment mechanism also slides to the appropriate position along with the movable sleeve 41, and the second handle is inserted into the corresponding second limit hole for secondary fixation and protection.

[0092] This invention utilizes the cooperation between the first safety bracket 1, the adjusting mechanism 4, the second safety bracket 2, the anti-detachment mechanism 4, and the safety rope fixing part 5. The adjusting mechanism 4 can move on or be fixed to the first safety bracket 1, and the safety rope fixing part 5 changes and is fixed according to the operator's working range. This allows the operator to select a suitable fixing point for the movable sleeve 41 based on the working position, thus reliably and stably protecting the operator's safety without restricting the operator's movement range on the slope, while ensuring the operator's safety and flexibility while working on the slope. The adjusting mechanism 4 is easy and simple to operate, and can be completed by a single person, improving the operator's work efficiency. The second safety bracket 2 provides secondary protection for the operator, forming a double layer of protection with the first safety bracket 1, increasing the safety factor of the operator and ensuring the operator's personal safety. The operator can select a suitable fixing point based on the working position. When the fixing point is close to the operator, the state of the safety rope can be directly observed and monitored in real time. Furthermore, the lever arm is short, the force is strong, and it is highly targeted.
