Description
Technical Field
The utility model relates to a transmission line equipment for the operation especially designs a jack-up pulley.
Background
Hoisting blocks are devices for securing the ropes of an elevator to a transmission line in electrical operation. The existing hoisting tackle consists of an inverted hook, a main pulley arranged in the hook and an auxiliary pulley arranged at the lower end of the hook. The hook opening of the hoisting hanging pulley is open, the unhooking phenomenon is easy to occur in the using process, the structural strength of the hook is low, the hook is easy to deform under the action of external force, and the potential safety hazard of operation exists.
Disclosure of Invention
The utility model relates to a solve above-mentioned technical problem, provide a jack-up hanging tackle, it can seal the hook mouth of couple, connects the both sides of couple simultaneously, improves couple structural strength, improves the operation security.
The technical solution of the utility model is that:
the hoisting hanging tackle comprises an inverted hook, a main pulley is installed in the hook, and an auxiliary pulley is installed at the lower end of the long edge of the hook, and is characterized in that: the hook is provided with a lifting frame which slides up and down, a sealing plate is hinged on the long edge of the hook, a linkage plate is connected between the lifting frame and the sealing plate through a pin shaft, the lower end of the short edge of the hook is provided with a lock pin, and the free end of the sealing plate is provided with a lock notch corresponding to the lock pin.
Further preferably, a tension spring is connected between the sealing plate and the hook, so that the sealing plate can return quickly.
Further preferably, a hanging ring is arranged at the top of the lifting frame, so that the insulating operating rod can be conveniently hooked.
Preferably, the lifting frame is provided with a sliding groove extending in the vertical direction, and the hook is provided with a positioning pin penetrating through the corresponding sliding groove.
The utility model has the advantages that:
1. because the lifting frame is vertically and slidably mounted on the hook, the sealing plate is hinged to the long edge of the hook, and the linkage plate is connected between the lifting frame and the sealing plate, when the lifting frame is used, the lifting frame moves downwards relative to the hook under the action of gravity, the linkage plate pushes the sealing plate to the short edge of the hook, the hook opening of the hook is sealed, the unhooking phenomenon is prevented, and the operation safety is improved.
2. Because the lock pin is arranged at the lower end of the short edge of the hook and the lock notch is arranged at the free end of the sealing plate, when the sealing plate seals the hook notch of the hook, the lock notch and the lock pin are mutually occluded, and the sealing plate plays a role in stretching between two edges of the hook, the structural strength of the hook is improved, and the operation safety is improved.

FIG. 2 is a right side view of FIG. 1;
in the figure: 1-hook, 2-main pulley, 3-auxiliary pulley, 4-lifting frame, 5-chute, 6-positioning pin, 7-hanging ring, 8-sealing plate, 9-linkage plate, 10-tension spring, 11-lock pin and 12-locking notch.
Detailed Description
As shown in fig. 1 and 2, the hoisting tackle comprises an inverted hook 1, a main pulley 2 is installed in the hook 1, a secondary pulley 3 is installed at the lower end of the long side of the hook 1, a lifting frame 4 which slides up and down is installed on the hook 1, a sliding chute 5 extending in the up-down direction is arranged on the lifting frame 4, a positioning pin 6 penetrating through the corresponding sliding chute 5 is installed on the hook 1, a hanging ring 7 is arranged at the top of the lifting frame 4, a sealing plate 8 is hinged on the long side of the hook 1, a linkage plate 9 is connected between the lifting frame 4 and the sealing plate 8 through a pin shaft, a tension spring 10 is connected between the sealing plate 8 and the hook 1, a lock pin 11 is installed at the lower end of the short side of the hook 1, and a lock opening 12 corresponding to the lock pin 11 is arranged at the free end of the sealing plate 8.
During operation, firstly, a ground operator penetrates a rope of the lifter through the auxiliary pulley 3, a lifting rope is installed on the hanging ring 7, the lifting rope is transmitted to an operator on a tower through the insulating operation rod, then the operator on the tower pulls the lifting rope to lift the lifting tackle to a power transmission line, in the lifting process, the hook 1 moves downwards relative to the lifting frame 4 under the action of gravity, the sealing plate 8 is pulled towards the long edge of the hook 1 by the linkage plate 9 to open the hook opening of the hook 1, the operator on the tower hooks the power transmission line by the hook 1 to enable the main pulley 2 on the hook 1 to be hung on the power transmission line, then the lifting rope is released, the lifting frame 4 moves downwards relative to the hook 1 under the action of gravity, the sealing plate 8 is pushed towards the short edge of the hook 1 by the linkage plate 9 to close the hook opening of the hook 1, finally, the ground operator enters the lifter and tightens up the rope of the lifter to lift the ground operator in the lifter to the power transmission line, and starting the operation.
The above description is only an example of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
