Description

Technical Field

[0001] This utility model belongs to the field of high-altitude operation protection technology, and relates to a high-altitude operation safety protection device. Background Technology

[0002] With the increasing emphasis on industrial safety, sampling operations in high-risk work environments, such as on dump trucks or vehicles without sideboards, pose a risk of falling. Currently, most existing methods involve operators wearing safety ropes with the top of the rope attached above the work position. However, the top of the safety rope can only move along a fixed straight line, which restricts the operator's range of motion and causes inconvenience to the operation. Utility Model Content

[0003] The purpose of this utility model is to provide a safety protection device for high-altitude operations, addressing the problems existing in the prior art.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A safety protection device for working at height includes a support frame. Multiple movable rods are arranged along the length of the support frame, and these rods are movable along the width of the support frame. Below each movable rod is a guide rail that moves along the length of the movable rod. A U-shaped movable frame is located at the guide rail. The movable frame is equipped with wheels, which are mounted on the guide rail. A safety rope is connected to the movable frame, and a safety belt is attached to the bottom end of the safety rope.

[0006] Furthermore, one end of the movable rod length protection line is provided with a first sliding groove and the other end is provided with a second sliding groove. The bracket is fixed with a first guide rail corresponding to the first sliding groove and a second guide rail corresponding to the second sliding groove along the width direction of the bracket. The first sliding groove is locked on the first guide rail and the second sliding groove is locked on the second guide rail.

[0007] Furthermore, each end of the guide rail along its length is connected to a connecting rod, and the top end of each connecting rod is fixed to a movable rod.

[0008] Furthermore, the guide rail is provided with a moving groove along its length, and the moving wheel is located in the moving groove.

[0009] Furthermore, an electric telescopic rod is fixed to the middle of the movable rod, and the end of the electric telescopic rod away from the movable rod is fixed to the bracket.

[0010] Furthermore, the movable rod is set horizontally.

[0011] Furthermore, the guide rail and the movable rod are arranged parallel to each other.

[0012] The beneficial effects of this utility model are as follows: by setting a guide rail that can move along the width of the support on the support, the top of the safety rope can move along the guide rail in the width of the support, which effectively increases the range of motion of the operator, making high-altitude operations more convenient and faster, and not restricted by the safety rope; the electric telescopic rod drives the movable rod and the guide rail to move, which has a simple structure and is convenient to use; and the manufacturing cost is low.

[0019] The present invention will now be described in detail with reference to the accompanying drawings:

[0020] like Figure 1-5As shown, a high-altitude work safety protection device includes a support 1. A horizontally arranged movable rod 2 is provided on the support 1 along its length. The movable rod 2 can move along the width of the support 1. Specifically, one end of the movable rod 2 has a first groove 3, and the other end has a second groove 4. A first guide rail 5 corresponding to the first groove 3 and a second guide rail 6 corresponding to the second groove 4 are fixed on the support 1 along its width. Both the first guide rail 5 and the second guide rail 6 are horizontally arranged. The first groove 3 is engaged with the first guide rail 5, and the second groove 4 is engaged with the second guide rail 6. The cross surfaces of the first guide rail 5 and the second guide rail 6 are rectangular. The first guide rail 5 and the second guide rail 6 support the movable rod 2 and ensure the direction of movement of the movable rod 2. To enable the movement of the movable rod 2, an electric telescopic rod 7 is fixed in the middle of the movable rod 2. The electric telescopic rod 7 is horizontally arranged along the width of the support 1 and is located away from the movable rod 2. One end of rod 2 is fixed to bracket 1. The movable rod 2 can be moved by the extension and retraction of electric telescopic rod 7. A guide rail 8 that can move with the movable rod 2 is provided below the movable rod 2 along its length. The guide rail 8 and the movable rod 2 are arranged parallel to each other. Specifically, each end of the guide rail 8 is connected to a vertically arranged connecting rod 9. The top of the connecting rod 9 is fixed to the movable rod 2. A U-shaped movable frame 10 is provided on the guide rail 8. The movable frame 10 is provided with a movable wheel 11. The movable wheel 11 is located on the guide rail 8 and can move back and forth along the length of the guide rail 8. When the movable wheel 11 moves, it can drive the movable frame 10 to move. The movable frame 10 is connected to a safety rope 12. The bottom end of the safety rope 12 is provided with a safety belt 13. The safety belt 13 adopts the existing conventional five-point safety belt. In order to ensure that the movable wheel 11 remains stable during movement and prevent it from falling off, a movable groove 14 is provided on the guide rail 8 along its length. The movable wheel 11 is located in the movable groove 14.

[0021] The usage of this utility model is as follows:

[0022] When operators are sampling on dump trucks or vehicles without sideboards, they only need to wear safety belts 13. When the operator moves along the length of the guide rail 8, they can pull the safety rope 12 during the movement, which will in turn move the moving frame 10 and the moving wheels 11 on the guide rail 8, so that the top of the safety rope 12 is always located near the operator. When the operator needs to move a large range along the width of the support, the electric telescopic rod 7 can be extended or shortened, which will in turn move the movable rod 2 and the guide rail 8 along the width of the support, and then move the moving frame 10 and the moving wheels 11, effectively expanding the range of movement and making the operation more efficient and convenient.
