Background

In recent years, along with the improvement of rural power grids and the implementation of mobile communication construction in China, the production and application of concrete electric poles are rapidly developed, at present, in the process of transporting, loading and unloading the concrete electric poles, a crane is usually adopted to match with a special clamp for the concrete electric poles to hoist and transfer the concrete electric poles, most of the clamps for the concrete electric poles are of a clamp type at present, however, when the clamps are used, when the diameter of the concrete electric poles is small, the clamping parts of the clamps interfere with each other, so that the concrete electric poles cannot be clamped continuously, only one or a narrow range of diameter concrete electric poles can be clamped, and the clamping and hoisting requirements of the concrete electric poles with different diameters cannot be well met. In addition, when the traditional concrete pole clamp is used for clamping a concrete pole, a worker is required to manually open the clamp so that the clamp can be smoothly clamped and embraced outside the concrete pole, and therefore, the operation is very inconvenient, time-consuming and labor-consuming.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above-mentioned not enough and providing one kind can adapt to the clamp of different diameter concrete poles well and embrace hoist and mount needs to the concrete pole fast loading and unloading anchor clamps of the clamping operation of very being convenient for.

The utility model discloses a solve above-mentioned technical problem and the technical solution who adopts as follows:

concrete pole fast loading and unloading anchor clamps, it is including mated rocker, axis, gallows, mated first iron chain, second iron chain, couple and mated arc splint, it is articulated that the X type is articulated through the axis to mated rocker, is provided with mated annular limiting plate at centraxonial middle part, mated arc splint fixed mounting is respectively at the lower tip of paired rocker, is provided with the claw lamella respectively on the upper portion of paired arc splint and lower part, and the claw lamella on the arc splint is crisscross relative in pairs, a tip of first iron chain in pairs is connected with the upper end of paired rocker respectively, and another tip of first iron chain in pairs is connected with the gallows respectively, a tip of second iron chain is connected with the gallows, the couple is connected with another tip of second iron chain, and the couple is hooked in epaxial between annular limiting plate in pairs.

The pair of swing frames are respectively provided with corresponding shaft holes, one end of the middle shaft is provided with a limiting head, the other end of the middle shaft is provided with an external thread, the middle shaft penetrates through the shaft holes of the pair of swing frames, and the nut is screwed on the external thread of the middle shaft and is welded and fixed on the middle shaft.

The utility model adopts the beneficial effect that above-mentioned technical solution can reach is:

1. when the paired arc-shaped clamping plates clamp the concrete electric poles, when the diameter of the concrete electric poles is small, the claw lobes on the paired arc-shaped clamping plates are arranged in a staggered mode, so that the corresponding claw lobes can be avoided through the grooves between the adjacent claw lobes, and the paired arc-shaped clamping plates have wider clamping range, so that the clamping requirements of concrete electric poles with different diameters are well met.

2. When the utility model is used, the hook of the crane is firstly hung on the hanger of the concrete pole quick loading and unloading clamp in the shape of figure 1, then the concrete pole quick loading and unloading clamp is moved to the position above the concrete pole to be clamped and hung by the crane, at the moment, as the gravity of the concrete pole quick loading and unloading clamp basically and completely acts on the second iron chain, the paired arc-shaped clamping plates keep the open state so as to be convenient for grabbing the concrete pole, when in grabbing, the paired arc-shaped clamping plates are placed on the ground by the crane through the claw petals at the lower part of the arc-shaped clamping plates and are positioned at the two sides of the concrete pole, then the hook is taken down from the middle shaft, then the crane is controlled to hoist, at the moment, the paired arc-shaped clamping plates can be driven by the paired swing frame to clamp the concrete pole, the operation is very convenient and fast, time and labor are saved.

Detailed Description

As shown in fig. 1, the clamp for rapidly assembling and disassembling the concrete pole comprises a pair of swing frames 1, a middle shaft 2, a hanger 3, a pair of first iron chains 4, a pair of second iron chains 5, a hook 6, a pair of arc-shaped clamping plates 7 and nuts 8, wherein the pair of swing frames 1 are hinged in an X shape through the middle shaft 2, and the position connection relationship between the pair of swing frames 1 and the middle shaft 2 is as follows: as shown in fig. 2, the paired swing frames 1 are respectively provided with corresponding shaft holes 9, one end of the middle shaft 2 is provided with a stopper 10, the other end of the middle shaft 2 is provided with an external thread 11, the middle shaft 2 penetrates through the shaft holes 9 of the paired swing frames 1, and the nut 8 is screwed on the external thread 11 of the middle shaft 2 and is welded and fixed on the middle shaft 2. The middle part of the middle shaft 2 is provided with paired annular limiting plates 12, the paired arc-shaped clamping plates 7 are respectively and fixedly installed at the lower end parts of the paired swing frames 1, as shown in fig. 2 and fig. 3, claw flaps 13 are respectively arranged at the upper parts and the lower parts of the paired arc-shaped clamping plates 7, grooves 14 are respectively formed between the adjacent claw flaps 13, the claw flaps 13 on the paired arc-shaped clamping plates 7 are staggered and opposite, one end parts of the paired first iron chains 4 are respectively connected with the upper end parts of the paired swing frames 1, the other end parts of the paired first iron chains 1 are respectively connected with the hanger 3, one end parts of the second iron chains 5 are connected with the hanger 3, the hook 6 is connected with the other end parts of the second iron chains 5, and the hook 6 is hooked on the middle shaft 2 between the paired annular.

The utility model discloses a concrete pole fast loading and unloading anchor clamps when using, hang the lifting hook of crane on this concrete pole fast loading and unloading anchor clamps's gallows 3 under figure 1 form earlier, then remove this concrete pole fast loading and unloading anchor clamps to the concrete pole top that needs to press from both sides and hang through the crane, at this moment because this concrete pole fast loading and unloading anchor clamps's gravity basically all acts on second iron chain 5, therefore paired arc splint 7 keeps open state, so as to snatch the concrete pole, when snatching, shelve paired arc splint 7 to subaerial through its claw lamella 13 of lower part through the crane, and make paired arc splint 7 be located the both sides of concrete pole, then take off couple 6 from axis 2, again control the crane lifts by crane, draw upward through paired first iron chain 4 at this moment, drive paired arc splint 7 through paired rocker 1 and press from both sides the concrete pole tightly, as shown in fig. 4, when the concrete pole has a small diameter, the claw lobes 13 of the paired arc-shaped clamp plates 7 are staggered, so that the corresponding claw lobes 13 can be avoided through the grooves 14, the paired arc-shaped clamp plates 7 have a wider clamping range, the clamping requirements of concrete poles with different diameters can be well met, and then the concrete pole clamped on the quick concrete pole handling clamp can be hoisted and transferred to a specified position through a crane.
