Description

Anti-fall safety device with adjustable working range

technical field

The utility model relates to an anti-fall safety protection device with adjustable working range.

Background technique

In the power operation and maintenance industry, maintenance personnel need to frequently perform high-altitude operations on the tower. In order to protect the safety of high-altitude operators, operators need to be equipped with safe and reliable protective equipment during high-altitude operations.

Most of the existing safety protection equipment is of "point" protection type. Before use, the safety protection equipment needs to be pre-suspended on the tower material. Due to the operating conditions on the tower, the hanging point of the safety protection equipment on the tower is not an ideal area. , The operator needs to protrude the suspension point laterally for operation. Once a fall occurs, the operator will swing greatly around the suspension point, which is prone to the danger of secondary impact (tower material) or electric shock. In addition, some safety protection equipment has a fixed length, which may cause the drop height difference to be too large and the drop impact force to be too large, which may cause injury to the operator's body. In addition, the above-mentioned safety protection measures greatly limit the activity radius of operators, which brings great limitations to the maintenance of transmission lines. Therefore, the power operation and maintenance industry needs a safety protection equipment that meets the working conditions of the industry.

An anti-fall safety protection device with adjustable working range, which is special in that it includes a safety rope, and a detachable two-way self-locking rope grab is installed in the middle of the safety rope. The detachable two-way self-locking rope grab The device is connected with the retractable speed difference fall arrester through the buffer. The safety ropes on the left and right sides of the detachable two-way self-locking rope grab are respectively installed with a first detachable rope grab and a second detachable rope grab. A detachable rope grabber, the first detachable rope grabber and the second detachable rope grabber are respectively connected with safety hooks.

The first detachable rope grab and the second detachable rope grab are both detachable one-way self-locking rope grabs.

The first detachable rope grab and the second detachable rope grab are respectively connected to the safety hook through the safety buckle, and the two ends of the buffer are also connected to the detachable two-way self-locking rope grab through the safety buckle respectively. Connect with retractable speed difference anti-drop device.

Aiming at the working conditions of the electric power operation and maintenance industry and the problems existing in the existing safety protection technologies and products, the device of the utility model proposes a safety protection device that can not only meet the needs of on-site operations, but also ensure the safety of operators. The following advantages: It has the structure design of quick assembly and disassembly, light weight and easy to carry; It can provide the protection of horizontal work movement for operators; The safety hanging point slides by itself; the working radius is adjustable, and the working area and working range are wide.

Detailed ways

As shown in FIG. 1 , the present invention provides an anti-fall safety protection device with adjustable working range, including a safety rope 5, and a detachable two-way self-locking rope grab 6 is installed in the middle of the safety rope 5. The detachable two-way self-locking rope grab 6 is connected with the retractable speed difference fall arrester 8 through the buffer 7, and the safety ropes 5 on the left and right sides of the detachable two-way self-locking rope grab 6 are respectively connected. A first detachable rope grab 2 and a second detachable rope grab 3 are installed, and the first detachable rope grab 2 and the second detachable rope grab 3 are respectively connected with the safety hook 1 .

The first detachable rope grab 2 and the second detachable rope grab 3 are both detachable one-way self-locking rope grabs. The first detachable rope grab 2 and the second detachable rope grab 3 are respectively connected to the safety hook 1 through the safety buckle 4, and the two ends of the buffer 7 are also connected to the detachable two-way through the safety buckle 4 respectively. The self-locking rope grab 6 is connected to the retractable speed differential fall arrester 8 .

Example 1:

The anti-fall safety protection device of the utility model consists of two sets of safety hooks, one part, two sets of detachable (one-way self-locking) rope grabs, one safety rope 5, and one set of detachable two-way self-locking rope grabs. 6. 1 set of buffers 7, 1 set of retractable speed difference fall arrester 8 and several safety buckles 4.

One set of safety hooks 1 is connected to one set of detachable rope grabbers through safety buckles 4 to form two sets of "safety hook + rope grabber" assemblies.

Two sets of "safety hook + rope grabber" components are connected to the safety rope 5 through the rope grabber. The rope grabber has a built-in spring self-locking mechanism. In the free state, the rope grabber and the safety rope 5 are in a locked state. After the person manually overcomes the spring force on the rope grab, the 2 sets of "safety hook + rope grab" components can adjust the position and spacing on the safety rope 5.

Among them, the detachable two-way self-locking rope grab 6 is connected with the safety rope 5, and the detachable two-way self-locking rope grab 6 has built-in two sets of spring self-locking mechanisms. In the free state, the rope grab and the safety rope 5 are locked. When the operator manually overcomes the spring force on the two sets of rope grabs at the same time, the detachable two-way self-locking rope grab 6 can adjust the working position on the safety rope 5. The buffer 7 is connected with the detachable two-way self-locking rope grab 6 through the safety buckle 4 , and the retractable speed difference fall arrester 8 is connected with the buffer 7 through the safety buckle 4 . Assembled according to the above method, a complete set of adjustable-length anti-fall safety protection equipment is formed.

The use method and working principle of the present utility model are:

Before use, assemble the above components as shown in Figure 1, and then hang the anti-fall safety protection equipment as follows (of course, according to the needs of the operation, hang it first, and then assemble it step by step):

Before hanging, first select the safety hanging point on the transmission tower, respectively hang 2 sets of "safety hook + rope grabber" components (two safety hooks 1 on the top) on the safety hanging point, and adjust the safety rope 5 according to the operation requirements. The length of the retractable speed difference fall arrester 8 is connected with the safety belt of the operator.

At this time, the adjustable length two-way self-locking backup protection equipment has the following three adjustment functions:

1. The length of the safety rope 5 is adjustable: the length of the safety rope 5 can be adjusted according to the distance between the safety hooking points, and the activity radius of the operator can also be increased according to the needs of the operation area. 2. The position of the detachable two-way self-locking rope grab 6 on the safety rope 5 can be adjusted: the operator can choose a safe fixed point at any position on the safety rope 5, which greatly increases the scope of the work area and is convenient for lateral movement operations. At the same time, it can also ensure the safety of work. 3. The retractable speed difference fall arrester 8 can be adjusted in length: it can provide workers with extended operation safety, and the automatic retractable and retractable function of the rope can minimize the height difference of personnel falling and reduce the impact on personnel.

At the end of the operation, the anti-fall safety protection equipment can be disassembled into several components for easy portability.

The beneficial effects of the present utility model also include:

1. Provides a set of reliable safety operation protection equipment and protection measures suitable for the transmission maintenance industry for transmission line maintenance operations.
