Description

Lifting device for installing ground wire hook

technical field

The utility model relates to the field of connecting grounding wires, in particular to a lifting device for installing a grounding wire hook.

Background technique

At present, when carrying out high-voltage inspection and maintenance, the high-voltage line must be grounded. Due to the large distance between the high-voltage line and the ground, it needs to be realized with the help of a longer operating rod. The general method is to first fix the hook connecting the grounding wire on the insulating rod, then hang the insulating rod on an operating rod, and then connect the grounding wire hook to the high-voltage line through the operating rod, and finally the insulating rod is lifted from the operating rod. Fall off naturally. However, there are several problems with this method of operation. First, because the hook and insulating rod have a certain weight, and the distance between the high-voltage line and the ground is relatively large, the operating rod must not only bear the load, but also ensure that the high-voltage line can be reached. In addition, the operating rod It cannot be too heavy and must ensure a certain strength, so the requirements for the operating rod are very high. When the current operating lever is hooked to the hook of the grounding wire, the operator is relatively laborious, and because the operating lever is long, when the hook is lifted, the operating lever is completely severe, and the top of the operating lever shakes seriously, resulting in the hook not being able to be fast and accurate The ground is connected to the high-voltage line, which affects the work efficiency of maintenance. the

Utility model content

The utility model provides a lifting device for installing a grounding wire hook, and aims to solve the problem that the current operating lever cannot quickly and accurately hook the grounding wire to the high-voltage line, thus affecting the work efficiency of maintenance.

The purpose of this utility model is achieved through the following technical solutions: the lifting device for installing the grounding wire hook includes a main rod, a secondary rod and a sleeve, the sleeve is sleeved on the main rod, and the secondary rod and the sleeve are connected through a hinge connection, the outer wall of the sleeve is provided with a hanging ring, the shape of the hanging ring is a square frame or a ring, and the plane where the hanging ring is located is parallel to the horizontal plane.

Further, the main rod is provided with a sliding groove, and the inner wall of the sleeve is provided with a guide wheel matched with the sliding groove.

Further, the lower end of the sleeve is provided with two parallel blocking rods, and the two blocking rods are located directly below the hanging ring.

Further, a groove is provided on the upper edge of the hanging ring.

Further, the main rod and the auxiliary rod are multi-section structures, and two adjacent rod bodies are connected by studs and screw holes.

The utility model has the following beneficial effects:

(1) The utility model adopts the combination form of the main pole and the auxiliary pole. The sleeve is sleeved on the main pole, and the main pole plays the role of main support. The rod is responsible for lifting the sleeve. When the sleeve rises to the top of the main rod, the auxiliary rod supports the sleeve and adjusts the angle of the hanging ring on the sleeve so that the hook is hooked on the cable. With the assistance of the auxiliary rod , the top of the main rod will not shake, and the hook is easier to hang on the cable accurately.

(2) The utility model sets two retaining rods on the sleeve. After the insulating rod is hung on the hanging ring, the lower end of the insulating rod is just stuck between the two retaining rods, which increases the stress point of the insulating rod and prevents insulation The lower end of the rod shakes and affects the stability of the hook at the upper end of the insulating rod, thereby facilitating installation and improving installation accuracy and efficiency.

(3) A groove is set on the hanging ring of the utility model, and a corresponding pendant is set on the insulating rod. The insulating rod is hung on the hanging ring through the pendant, and the pendant is correspondingly stuck in the groove, so that the insulating rod cannot be hung along the hanging ring. The ring moves in a circle, that is, the position of the hook is relatively fixed, which is convenient for hooking the hook on the cable.

Detailed ways

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto.

Example 1:

As shown in Figure 1, the lifting device for installing the grounding wire hook described in this embodiment includes a main rod 1, an auxiliary rod 2 and a sleeve 3, the sleeve 3 is sleeved on the main rod 1, and the auxiliary rod 2 is connected to the main rod 1. The sleeve 3 is connected by a hinge, and the outer wall of the sleeve 3 is provided with a hanging ring 4. The shape of the hanging ring 4 is a square frame or a circular ring, and the plane where the hanging ring 4 is located is parallel to the horizontal plane.

As shown in Figure 2, hang the insulating rod with the hook on the hanging ring 3, keep the main rod 1 in a vertical state, adjust the auxiliary rod 2, and make the sleeve 3 slowly move to the top of the main rod 1, and the sleeve 3 When the hooking point is reached, control the position and direction of the hook through the secondary lever 2, and then cooperate with the main lever 1 to hook the hook to the cable.

When hooking the grounding wire hook, although two people are required for the operation, one person holds the main rod and the other controls the auxiliary rod, but the operation of the two people is relatively labor-saving. Compared with the traditional hook operation rod, not only the operation The efficiency is higher, and the whole movement of the hook is relatively stable, the hook will not shake at the top of the main pole, and it is easy to quickly hook the hook to the cable.

Example 2:

As shown in Figure 3, this embodiment is basically the same as Embodiment 1, the difference is that this embodiment is provided with a chute on the main rod 1, and the inner wall of the sleeve 3 is provided with a guide wheel 5 matched with the chute , so that the movement of the sleeve 3 is more labor-saving, reduces the labor intensity of the sub-rod operator, and is also conducive to the rapid lifting of the sleeve 3 .

Example 3:

As shown in Figure 4, this embodiment is basically the same as Embodiment 1, the difference is that the lower end of the sleeve 3 of this embodiment is provided with two parallel retaining rods 6, and the two retaining rods 6 are located at the ends of the hanging ring 4. Directly below, when the insulating rod is hung on the hanging ring 4 of the sleeve 3, the lower end of the insulating rod is just stuck between the two retaining rods 6. Through the action of the hanging ring 4 and the retaining rod 6, the upper and lower ends of the insulating rod All will not shake, thereby enhancing the stability of the hook at the upper end of the insulating rod, facilitating installation, and improving the accuracy and efficiency of installation.

Example 4:

As shown in Figure 5, this embodiment is basically the same as Embodiment 3, except that the upper edge of the hanging ring 4 of this embodiment is provided with a groove 7. Generally, to hang the insulating rod on the hanging ring 4, a corresponding pendant needs to be set on the insulating rod, and the insulating rod is hung on the hanging ring 4 by the hanging piece. The circular rotation of the hanging ring causes the opening direction of the hook to change, thereby affecting the hooking of the hook. For this reason, in this embodiment, a groove 7 is provided on the hanging ring 4. After the insulating rod is hung on the hanging ring 4, the pendant is correspondingly stuck in the groove 7, so that the insulating rod cannot move in a circle along the hanging ring 4, that is, The hook does not rotate, and the opening position of the hook is relatively fixed, which is convenient for hooking the hook on the cable.

Example 5:

This embodiment is basically the same as Embodiment 4, the difference is that the main rod 1 and the auxiliary rod 2 of this embodiment are multi-section structures, and the two adjacent rod bodies are connected by studs and screw holes, so as to facilitate the adjustment of the main rod 1 And the length of the auxiliary rod 2, it is also convenient for storage.
