Description

Multifunctional spreader for lifting equipment

technical field

The utility model relates to an engineering machine, in particular to a multifunctional lifting device for hoisting equipment.

Background technique

The lifting equipment starts a vertical or vertical and horizontal working stroke after retrieving the material, unloads after reaching the destination, and then travels empty to the reclaiming location to complete a working cycle, and then carries out the second lifting or handling. Generally speaking, when the lifting equipment is working, retrieving, moving and unloading are carried out in sequence, and the work of each corresponding mechanism is intermittent. Lifting equipment is mainly used to carry items, equipped with grab buckets to carry bulk materials such as coal, ore, and grain, and equipped with buckets to lift liquid materials such as molten steel. Some lifting machinery such as elevators can also be used to carry people. Lifting equipment can be divided into light and small lifting equipment, elevators, cranes and overhead monorail systems according to different structures.

Existing lifting equipment, such as commonly used cranes, electric hoists, etc., are generally only equipped with a single spreader, such as a single hook or grab, which can only carry large objects or bulk materials. The range is limited. If the lifting equipment is equipped with a hook, when you want to move bulk materials, you have to pack them first or borrow other auxiliary tools to carry them, which reduces work efficiency and poor practicability.

Utility model content

Aiming at the deficiencies in the prior art, the utility model provides a multi-functional hoisting device for lifting equipment. The hoisting device can be used as a hook or as a grab bucket, with comprehensive functions and a wide application range, without the need for other auxiliary tools. , high work efficiency and good practicability.

In order to achieve the above object, the technical scheme that the utility model takes:

The multifunctional spreader used for lifting equipment includes a mounting beam, a vertically arranged and retractable hook hydraulic cylinder is arranged in the middle of the mounting beam, and a hook is connected to the bottom end of the hook hydraulic cylinder. The two sides of the installation beam are symmetrically provided with support rods, the two support rods are vertically arranged, and the bottom ends are all hinged on a grab bucket, and the grab bucket is also symmetrically provided with two telescopic grab bucket hydraulic cylinders. The grab hydraulic cylinder is fixed on the installation beam and is located between the support rod and the hook hydraulic cylinder.

As an optimal technical solution, in order to make the grab easy to open on both sides, facilitate the work of the hook, realize the multi-function of the spreader, and at the same time ensure that the grab is fastened on the installation beam to improve safety performance, the grab is all connected by a hinge and The strut and grab hydraulic cylinder are connected.

As an optimal technical solution, in order to control the volume of the hook, thereby reducing its own weight, while ensuring sufficient strength of the hook and prolonging its service life, the hook is made of 34Cr2Ni2Mo material.

Compared with the prior art, the utility model has the beneficial effects:

1. By setting a retractable hydraulic cylinder, it is convenient and quick to realize the transformation and use between the hook and the grab, and change the defect of the existing singleness of the spreader. It has comprehensive functions and a wide range of applications. Work efficiency, good practicability.

2. The grab is connected with the support rod and the grab hydraulic cylinder through hinges. On the one hand, the grab is easy to open on both sides, which is beneficial to the work of the hook and realizes the multi-function of the spreader. On the other hand, it ensures that the grab is fastened to the installation On the beam, improve safety performance.

3. The hook body is made of 34Cr2Ni2Mo material, which controls the volume of the hook body to reduce its own weight, while ensuring sufficient strength of the hook body and prolonging its service life.

detailed description

Propose a kind of concrete embodiment of the present utility model as shown in Figure 1, the multifunctional hoisting gear that hoisting equipment is used, comprises installation crossbeam 1, and the middle part of described installation crossbeam 1 has a vertically arranged, and retractable hook hydraulic cylinder 2. The bottom end of the hook hydraulic cylinder 2 is connected with a hook 3, and the two sides of the installation beam 1 are symmetrically provided with support rods 4, and the two support rods 4 are vertically arranged, and the bottom ends are hinged on a On the grab bucket 5, there are also two telescopic grab bucket hydraulic cylinders 6 symmetrically arranged on the grab bucket 5, and the two grab bucket hydraulic cylinders 6 are fixed on the installation beam 1, and both are located between the support rod 4 and the hook hydraulic pressure. Between the cylinders 2, that is, on the installation crossbeam 1, a support rod 4, a grab hydraulic cylinder 6, a hook hydraulic cylinder 2, a grab hydraulic cylinder 6, and a support rod 4 are arranged in sequence.

The grab buckets 5 are all connected with the struts 4 and the grab hydraulic cylinders 6 through hinges, and the hinges can be installed on the grab buckets 5 first, and then connected with the struts 4 and the grab hydraulic cylinders 6 respectively. Bucket 5 is convenient for both sides to strut, is beneficial to the work of suspension hook 3, realizes the multifunctionality of spreader, guarantees that grab bucket 5 is fastened on the installation crossbeam 1 on the other hand, improves safety performance.

The hook 3 is made of 34Cr2Ni2Mo material. The characteristics of 34Cr2Ni2Mo structural steel are high strength, toughness, good hardenability and stability against overheating. On the one hand, the volume of the hook 3 is effectively reduced. Thereby reduce its dead weight, guarantee that suspension hook 3 has enough strength on the other hand, thereby prolong its service life.

When the utility model is in use: the spreader is installed on lifting equipment such as a crane or an electric hoist, and the two grab hydraulic cylinders 6 and the hook hydraulic cylinder 2 are all controlled by an electrical controller. The two grab hydraulic cylinders 6 are extended downward, and the support rods 4 at both sides are stressed, so that the grab bucket 5 is opened to both sides, and then the hook hydraulic cylinder 2 is extended to realize the use of the hook 3; When grab bucket 5, only need shorten the length of hook hydraulic cylinder 2, make it be positioned at the top of grab bucket 5 and get final product. It is easy to convert and has a wide range of applications.
