Abstract
The utility model relates to a prevent cross damping conductor spacer that gripper drops, including body frame and gripper, four gripper of symmetry installation on the body frame, gripper is including gripping the claw apron, and gripper fixed plate, apron axle, gripper apron pass through the connecting axle with the one end of gripping the claw fixed plate and are connected, and the other end passes through the apron hub connection, and the system has the bolt hole on gripper fixed plate and gripper apron, wears to adorn fastening bolt in the bolt hole. The utility model discloses increase fastening bolt between holding claw apron and holding claw fixed plate, make the holding claw connect more stable, be difficult to drop, reform transform with low costs.
Description
Technical Field
The utility model belongs to the technical field of transmission line, a line fixed equipment is related to, especially a prevent cross damping conductor spacer that holding claw drops.
Background
The FJZ-45400S-shaped cross-shaped damping spacer is a common spacer form for four-bundle conductors at present, as shown in figure 1, the spacer is arranged between the bundle conductors and is connected with the bundle conductor through 4 holding claws 1, the main frame 2 plays a role in supporting, separating and damping the conductors, and the holding claws hold the bundle conductor. As shown in fig. 2, the movable part on the gripper is a gripper cover plate 4, the gripper cover plate is connected with a gripper fixing plate 9 through a connecting shaft 7, a cover plate shaft 5 passes through a cover plate shaft hole 6 and is fixed by a closed pin at one side shaft end, the cover plate shaft presses the gripper cover plate, and a wire is gripped through a wire clamp rubber 8 embedded in the gripper as shown in fig. 2. However, when in use, the cross-shaped damping spacer has the following problems:
1. under the normal vibration of conductor spacer during operation, apron axle and apron pressurized position are stress concentration region, and this region vibrates for a long time, collides, and wearing and tearing appear very easily, takes place apron shaft hole and wears out, the round pin that closes off drops scheduling problem, causes the apron axle to drop. Because the movable part of the cover plate is only fixed in this way, the gripper cover plate can be opened after the cover plate shaft falls, and the conductor can be worn by the remaining part of the gripper.
2. The connecting shaft is the optical axis, and installer pounces the deformation with connecting shaft spacing hole 3 after packing into the connecting shaft when installing the conductor spacer, and the spacing hole after the deformation can restrict the connecting shaft and deviate from. However, the hitting power degree can not be guaranteed during installation, the deformation degree of most of the limiting holes is insufficient, the connecting shaft can be directly separated, or the connecting shaft is loosened under normal vibration during the operation of the spacer rod, hits the limiting holes, wears the deformation parts of the limiting holes and further separates.
The spacer after falling off has no fixing effect on the wire, and under the action of breeze oscillation, wire vibration and the like, the residual spacer is easy to collide with the wire, so that the wire is damaged, and the wire breakage accident is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a connection stability height, simple installation, the cross damping conductor spacer that prevents holding the claw and drop that does not receive installer's operation influence.
The utility model provides a technical scheme that technical problem adopted is:
the utility model provides a prevent cross damping conductor spacer that gripper drops, includes the body frame and grips the claw, four gripper of symmetry installation on the body frame, grip the claw including holding the claw apron, grip claw fixed plate, apron axle, grip claw apron and the one end of holding the claw fixed plate pass through the connecting axle and connect, and the other end passes through the apron hub connection, holds the claw fixed plate and holds the claw cover and go up the system and have the bolt hole, wears to adorn fastening bolt in the bolt hole.
And, closed pins are installed at both ends of the connecting shaft.
Further, an anti-slip washer is attached to the head of the fastening bolt.
The utility model has the advantages that:
1. the utility model discloses increase fastening bolt between holding claw apron and holding claw fixed plate, make the holding claw connect more stable, be difficult to drop, reform transform with low costs.
2. The utility model discloses change the connecting axle into the round pin axle by the optical axis, the simple installation does not receive installer's operation influence, and the reliability is higher.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A cross-shaped damping spacer for preventing holding claws from falling comprises a main frame 2 and holding claws 1, wherein four holding claws are symmetrically arranged on the main frame. The gripper is shown in figure 3 and comprises a gripper cover plate 4, a gripper fixing plate 9, a cover plate shaft 5 and a gripper cover plate, wherein one end of the gripper fixing plate is connected with one end of the gripper cover plate through a connecting shaft 7, and the other end of the gripper cover plate is connected with the other end of the gripper cover plate through a cover plate shaft.
Both ends of the connecting shaft are provided with closed pins 11 to prevent the connecting shaft from falling off from the shaft hole.
In order to increase the connection strength of the holding claw fixing plate and the holding claw cover plate, the holding claw fixing plate and the holding claw cover plate are connected through bolts 10, bolt holes are formed in the holding claw fixing plate and the holding claw cover plate, and fastening bolts penetrate through the bolt holes. And an anti-slip washer 12 is installed at the head of the fastening bolt.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the spirit of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
