Description

Technical Field

[0001] The utility model belongs to the technical field of transformer product manufacturing, and specifically relates to a cable-threading type bushing installation auxiliary device. Background Art

[0002] Bushing installation is a very important part of transformer assembly process. Cable bushing is widely used in transformers. When installing cable bushing, the cable with welded joints needs to be passed through the inner cavity of the bushing to the top of the bushing. After the joint is connected to the traction rope during installation, the traction operator tightens the traction rope to lift the cable. In order to meet the insulation performance requirements in the air, the bushing is often arranged at an angle with the body. Some transformer bushings are even arranged at multiple angles with the transformer body.

[0003] During the installation of the transformer cable-threading bushing, the traditional installation method has the following disadvantages: 1. During the installation process, it is impossible to ensure that the cable pulling rope is in the same direction as the bushing, and it cannot be installed in place at one time, and needs to be adjusted again, which affects work efficiency; 2. The operation is difficult and it is impossible to avoid the collision between the joint and the inner cavity of the bushing during the lifting process, and the installation quality is not high. In the face of the above problems, there is an urgent need for a cable-threading bushing installation auxiliary device that can make the cable pulling rope always consistent with the direction of the bushing and in the center of the bushing, reduce the difficulty of operation, and improve the installation efficiency and installation quality. Utility Model Content

[0006] A cable-threading casing installation auxiliary device comprises a fixing plate; the fixing plate is provided with a plurality of support plate assemblies, the support plate assemblies are used to position a traction rope, the fixing plate is provided with a mounting hole and a through hole for passing the traction rope, and the mounting hole can fix the auxiliary device to the top of the casing.

[0007] The support plate assembly comprises a support plate and a guide wheel; the support plates are grouped in pairs, and a guide wheel is installed on the upper end of each group of support plates, and the support plate assembly is inclined toward the through hole of the fixed plate.

[0008] Furthermore, a fixing seat is provided at the lower end of the support plate assembly, and the fixing seat is connected to the fixing plate.

[0009] Furthermore, the fixing seat is fixedly connected to the fixing plate by bolts.

[0010] Furthermore, both ends of the guide wheel are connected to the upper end of the support plate through a connecting piece.

[0011] Furthermore, the guide wheel is not connected to the two ends of the support plate, and the cross section is a concave arc shape, and the cross sections of multiple guide wheels form a circular hole.

[0012] Furthermore, a bearing is arranged inside the guide wheel, which can effectively reduce the friction of the traction rope during the lifting process of the casing joint.

[0013] Furthermore, a buffer structure is provided at the bottom of the fixing plate.

[0014] Furthermore, the buffer structure is made of rubber.

[0015] Furthermore, the mounting hole is fixed to the top of the sleeve by bolts.

[0016] Compared with the prior art, the utility model has the following beneficial technical effects:

[0017] The utility model passes the casing connection head and the traction rope through the opening on the fixing plate, extends into the casing cavity to lift and adjust the casing angle, and after the casing is lifted to just above the installation position, the traction rope is lowered to connect with the casing connection head; the traction operator tightens the traction rope and ensures that the traction rope is in a tense state during the casing falling process until the casing installation is completed.

[0018] The support plate assembly of the utility model is provided with a plurality of guide wheels. Since the circular hole formed by the plurality of guide wheels is located in the center of the casing cavity, the tense traction rope is also located in the center of the casing cavity under the restriction of the guide wheels, so that the cable traction rope is always consistent with the direction of the casing and is located in the center of the casing, so that the movement direction of the cable joint in the entire traction and lifting process is consistent with the traction rope, and a certain deviation of the traction rope angle is allowed; a bearing is arranged inside the guide wheel, which can effectively reduce the friction of the traction rope during the lifting process of the casing joint and reduce labor intensity; the utility model reduces the difficulty of operation while improving the installation quality.
