Description

Working protection bracket for tower cable platform

technical field

The utility model relates to the field of electric power construction, in particular to a work protection bracket for a pole tower cable platform.

Background technique

With the acceleration of urbanization, from the perspective of urban environmental protection and the use of limited space resources and the construction of urban beauty, in urban construction and renovation planning, it is often required that the above-ground pipelines enter the ground to maintain the beautiful appearance of the city. Therefore, it is an inevitable choice for the power grid to change from the form of overhead lines to the form of underground cables.

There are two types of towers for overhead lines: iron towers and steel pipe poles. For the cable terminal tower of the steel pipe pole, the cable platform or the independent cable platform are often set on the pole according to the voltage level. The cable platform is the place where the overhead wires and cables are connected. In order to prevent the idlers from boarding and the construction personnel to work up and down, it is generally set at a height of 6 meters above the ground. When the staff installs cable accessories or maintenance equipment on the cable platform, it belongs to high-altitude operations. According to the requirements of the regulations, personal protective equipment such as seat belts and safety ropes must be used to prevent accidents of personnel falling from heights. However, because there is no component to hang the safety belt above the cable platform, the staff can only hang the safety belt on the platform, resulting in the safety belt "hanging high and using low", which violates the requirements of the "State Grid Corporation of Electricity Safety Work Regulations", and there are serious problems. Personal safety hazard. How to ensure the safety of the staff when working on the cable platform has become an urgent problem for electric workers.

Contents of the invention

The technical problem to be solved by the utility model is to provide a work protection bracket for a pole tower cable platform with high safety.

In order to solve the above-mentioned technical problems, the utility model includes a horizontal arm and a diagonal support connected to the cross arm. The cross arm is provided with a plurality of hanging points. One end of the diagonal support is hinged in the middle of the cross arm, and the other end is There is a hanging ring, on one side of the pole tower and above the cable platform, there are two connecting plates up and down correspondingly, wherein a fixing rod is also arranged on the upper connecting plate, and the hanging ring of the oblique support can be set on the fixing rod, The oblique supports and cross arms are respectively mounted on corresponding connecting plates and fixed with bolts.

The hanging points on the cross-arm are equidistantly arranged and the distance between two adjacent hanging points is 20cm.

Both the cross arm and the oblique support are made of angle steel or channel steel.

The fixing rod includes a rod body vertically arranged on the connecting plate and a baffle arranged at the end of the rod body, and the rod body is also provided with anti-skid lines.

The beneficial effect of the utility model is: the utility model adopts the cross arm and the oblique support to form a triangular stable structure with the tower body of the pole tower, which has strong stability. Higher than falling; and the design of multiple hanging points can meet the requirements of multiple construction workers working on the cable platform at the same time; in addition, the design of the hanging ring and the fixing rod can play an auxiliary role in the process of installation and disassembly, which is convenient disassembly.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

Referring to Fig. 1 and Fig. 2, the work protection bracket of the pole tower cable platform of the present utility model includes a cross arm 1 arranged horizontally and a diagonal support 2 connected with the cross arm 1, and a plurality of hanging points 3 are arranged on the cross arm 1, so that One end of the oblique support 2 is hinged to the middle of the cross arm 1, and the other end is provided with a hanging ring 4. On one side of the pole tower 5 and above the cable platform, two connecting plates 6 are correspondingly arranged up and down. A fixed rod 7 is provided, and the hanging ring 4 of the oblique support 2 can be set on the fixed rod 7. The oblique support 2 and the cross arm 1 are respectively installed on the corresponding connecting plates 6 and fixed by bolts.

The hanging points 3 on the cross arm 1 are arranged at equal intervals and the distance between two adjacent hanging points 3 is 20cm.

Both the cross arm 1 and the diagonal support 2 are made of angle steel or channel steel.

The fixing rod 7 includes a rod body 71 vertically arranged on the connecting plate and a baffle 72 arranged at the end of the rod body 71 , and the rod body 71 is also provided with anti-skid lines. Such a design can ensure the relative stability between the fixed rod 7 and the hanging ring 4 . And the hanging ring 4 is sleeved on the fixed rod 7, which can play an auxiliary role in the process of installation and disassembly, and the installation is labor-saving and convenient for disassembly.

The utility model is mainly used for installing cable accessories or overhauling the cable platform, and is suitable for the safety guarantee of the work on the platform before the power transmission of the line. After the construction is completed, the component is removed.

The protection bracket of the utility model is arranged on the body of the pole tower, and is about 2 meters higher than the cable platform, and is used for construction personnel to hang safety belts or safety ropes to prevent personnel from falling. The cross arm, diagonal support and tower body form a triangular stable structure to increase its stability, wherein the cross arm, diagonal support and tower body are connected by bolts. A safety belt hanging point is set every 20cm on the cross arm to meet the requirements of multiple construction workers working on the cable platform at the same time. During the production of the tower, the manufacturer reserves a hanging point for the installation of the protective bracket, which is installed when the tower is erected, so as to prepare for the subsequent installation of the cable platform accessories. After the cable accessories are installed, the protective bracket can be removed and handed over to the operating unit for safekeeping for use in future platform maintenance.

In summary, the content of the present utility model is not limited to the above-mentioned embodiments, and those skilled in the art can propose other embodiments within the technical guidance of the present utility model, but these embodiments are all included in this disclosure. within the scope of utility models.
