Description

A cement pole hoisting auxiliary fixture

technical field

The invention belongs to an auxiliary tool for electric power construction, in particular to an auxiliary fixture used for hoisting cement poles.

Background technique

During the construction process of the distribution network, operators often need to complete the distribution or transfer of cement rods. Before the present invention was made, such distribution or transfer was usually completed by traditional methods. After the supplier transports the cement pole to the warehouse of the power supply enterprise, there are two traditional methods of unloading the truck. One is to use a crane to lift it, and first fix it on the pole with a hemp rope or a steel wire rope. The fixing method can be single point or double point , to complete the lifting and unloading. The second is to use the ramp to roll off manually. The problems of the former are: the crane is bulky and heavy, the ropes are cumbersome, and the site requirements are high. Moreover, the distribution network usually uses small and medium-sized conical poles. Hiring a crane is not only overkill, but also expensive. The latter is difficult to guarantee the quality of the work, the damage rate is high, there are many limiting factors, time-consuming and labor-intensive, and the efficiency is low.

Contents of the invention

In order to overcome the above-mentioned problems in the prior art, the present invention aims to provide an auxiliary fixture for lifting cement poles. With the assistance of the fixture, operators can easily complete the distribution and transfer tasks of cement poles by using forklifts or cranes. , has the advantages of saving time and labor and high efficiency.

To achieve the above object, the present invention adopts the following technical solutions:

The feature of this cement pole hoisting auxiliary fixture is that it includes a beam on which two axially distributed forklift brackets are symmetrically arranged, and a set of arm claws are suspended at both ends of the beam. Components; each set of arm claw components is hinged from a connecting ring, a telescopic arm, a connecting arm and an arm claw in sequence from top to bottom.

During specific implementation, the arm claw is composed of two relatively hinged bent pieces.

During specific implementation, the forklift bracket is arranged on the top of the beam.

During specific implementation, two lifting rings are symmetrically arranged on the beam.

During specific implementation, a friction plate is provided on the inner side of the two relatively hinged bent pieces.

Beneficial effects: the invention adopts the principle of lever transmission and self-tightening by weight, and after the forklift bracket, suspension ring and arm claw assembly are axially arranged on the beam, the two loading and unloading tools of the forklift and the crane are assisted in loading, unloading and lifting work. When the forklift is working, you only need to align the forklift arm with the forklift bracket and fork in. The center of gravity of the conical cement pole is generally located at 1/3 of the root. Before lifting the forklift, place the two arm claws on both sides of the center of gravity of the cement pole to clamp the cement pole. When the forklift arm is lifted, the telescopic arm moves upward and the arm The claws are clamped inward to form a V-shaped support structure, which firmly holds the cement pole, and the loading and unloading of the cement pole is realized by using the spatial movement capacity of the forklift. In the same way, when the crane is working, it is only necessary to connect the two hoisting rings with a wire rope and hang them on the crane hook. Therefore, with the assistance of the fixture, the operator can easily complete the distribution and transfer tasks of the cement poles through a forklift or a crane, which has the advantages of saving time, labor and high efficiency.

Below in conjunction with accompanying drawing, the present invention will be further described through embodiments.

Description of drawings

Fig. 1 is a schematic diagram of the front view structure of an embodiment of the present invention. For the convenience of illustration, the arm claw assembly has been rotated 90° in the figure.

FIG. 2 is a schematic structural diagram of the left view of FIG. 1 .

Among the figure: arm claw 1, friction plate 11, connecting arm 2, telescopic arm 3, beam 4, forklift bracket 5, suspension ring 6, hinge shaft 7, connecting ring 8, limit plate 9, tapered pole A.

Detailed ways

See Figure 1. This cement pole hoisting auxiliary fixture includes a beam 4, and the top of the beam 4 is symmetrically provided with two axially distributed forklift brackets 5, and the shape and size of the forklift brackets 5 are suitable for the blades of the forklift. match. Respectively hang a set of arm claw assembly at the two ends of crossbeam 4. Each set of arm claw assembly is hinged by connecting ring 8, telescopic arm 3, connecting arm 2 and arm claw 1 successively from top to bottom. The arm jaw 1 is composed of two relatively hinged bent pieces. In order to adapt to the use of the crane, two suspension rings 6 can also be symmetrically arranged on the beam 4 during specific implementation. In addition, in order to increase the coefficient of friction, friction plates 11 can be fixedly arranged on the inner surfaces of the two relatively hinged bent pieces to prevent slipping and decoupling during hoisting.

During specific manufacture, the crossbeam 4 is a hollow pipe, and the connecting ring 8 is suspended on the crossbeam 4 through the hanging rod. In order to prevent the suspended arm claw assembly from rotating 360° and affecting the suspension, a limit plate 9 is set on one side of the crossbeam where the connecting ring 8 and the crossbeam 4 are connected, so that the connecting ring 8 can only swing at a certain angle . In actual use, the tapered pole A in Figure 1 should be parallel to the beam 4 up and down.

When working, first make the arm claw assembly in a loose state, open the opening around the hinge shaft with two bent pieces, and then clamp the opened arm claw on the side of the center of gravity of the tapered electric pole A, and the two sets of arm claw assemblies One set on the side, then, insert the two shovel blades of the forklift in the bracket 5 of the forklift for hoisting. In the same way, during the crane operation, only two suspension rings 6 need to be connected with wire ropes and hung on the crane hook.

The above-mentioned embodiments are only used to explain the inventive concept of the present invention, and should not be regarded as limitations on the structure of the present invention. All simple deformation structures inspired by the embodiments should be considered as falling within the scope of protection of the present invention.
