Abstract

The utility model relates to a hydraulic pay-off rack, which belongs to the technical field of design and manufacture of a pay-off rack for erection and maintenance of power transmission lines. There is a main support on the reinforcing rib of the base. A bearing is provided at the center of the bearing fixing plate. There is a jack on top of the block. There are rear support frames on both sides of the main support. There are traveling wheels on the traveling wheel fixing plate. The use of the utility model is to take two pay-off racks as a group. When in use, push the wire reel between two pay-off frames, and adjust the height of the bearing fixing plate by a jack. Then thread the spool shaft into the bearing core hole, and then the wire can be released. Because the utility model is equipped with bearings, the rotation of the wire reel shaft becomes brisk, and the labor intensity of the wire pulling personnel is reduced. In addition, due to the walking wheels, it can be pushed and walked when encountering complex terrain, without the need for many people to lift and carry it. In addition, because the two pay-off frames are relatively upright, there is no need to lengthen the length of the wire reel shaft. In turn, the weight of the corresponding components is reduced. It saves time and labor in many ways, thus improving work efficiency. The existing problems of existing products are solved.

Description

Hydraulic pay-off stand

technical field

The utility model belongs to the technical field of design and manufacture of a pay-off frame for erection and maintenance of transmission lines.

Background technique

The pay-off rack used in transmission line erection or maintenance is a tapered frame type at present, is to have four oblique tendons on the four sides of the square base, and the top of the tapered frame has a coil shaft support. The bobbin support is adjusted by the lead screw. When in use, two pay-off racks form a group, and the wire reel shaft is placed on the wire reel shaft support. When setting out, the operator pulls the lead, and the reel shaft is dry-frictioned and rotated on the reel shaft holder. Because the lead reel is particularly heavy, the puller will spend a lot of energy. In addition, the pay-off frame has a large volume and a large weight, and it is particularly laborious to carry when encountering complex terrain. It is also very difficult to adjust the lifting of the reel support by turning the screw with a wrench. In addition, because it is a tapered support, the length of the wire reel shaft is required to be large, otherwise the oblique tendons will block the rotation of the wire reel.

Contents of the invention

In view of the above situation, the purpose of this utility model is to provide a pay-off stand which is small in size and saves time and effort in operation and handling, so as to solve the practical problems existing in the existing equipment.

The technical solution adopted by the utility model to solve the technical problem is: it is composed of a base and a main support. There is a reinforcing rib in the middle part of the base, and a main support is arranged on the reinforcing rib. There are sliding slots inside the main bracket. There is a bearing fixing plate in the chute. A bearing is provided at the center of the bearing fixing plate. There is a spacer base above the base stiffener. There is a spacer on the top of the spacer base. There is a jack on top of the block. The upper end of the jack is against the bottom of the bearing fixing plate. There are rear support frames on both sides of the main support. There is a jack pressure bar on the rear support frame. There are traveling wheel fixing plates on both sides of the rear part of the base. There are traveling wheels on the traveling wheel fixing plate. The use of the utility model is to take two pay-off racks as a group. When in use, push the wire reel between two pay-off frames, and adjust the height of the bearing fixing plate by a jack. Then thread the spool shaft into the bearing core hole, and then the wire can be released. Because the utility model is equipped with bearings, the rotation of the wire reel shaft becomes brisk, and the labor intensity of the wire pulling personnel is reduced. In addition, due to the walking wheels, it can be pushed and walked when encountering complex terrains, without the need for many people to lift and carry it. In addition, because the two pay-off frames are relatively upright, there is no need to lengthen the length of the wire reel shaft. In turn, the weight of the corresponding components is reduced. It saves time and effort in many ways, thus improving work efficiency. The existing problems of existing products are solved.
