Description

A retractable electric suspension crane

technical field

The utility model relates to a novel electric suspension crane, in particular to a retractable electric suspension crane.

Background technique

The traditional electric suspension cranes run on two I-steel rails in the one-span workshop, and the electric hoist runs on the lower part of the main girder of the crane, and the effective working area is limited within the one-span range. With the development of industry, standardized factory buildings are basically multi-span, and the production process between each span needs to be coordinated or assembled. This requires that the hoisted objects between two adjacent spans need to be transferred across regions. The existing electric suspension cranes cannot solve this problem. The problem is that the secondary handling can only be carried out by flatbed trucks or forklifts, which not only adds additional equipment but also takes a lot of time and labor. Therefore, a new type of crane needs to be designed to solve the above problems.

Utility model content

In view of the above problems, the utility model aims to design a retractable electric suspension crane that meets the needs of the domestic and foreign markets, enables it to have the basic functions of a suspension crane, and can work across regions and greatly increase the working area.

In order to achieve this technical purpose, the solution of the utility model is: a telescopic electric suspension crane, including a cart running mechanism, a reverse roller, a main beam, an electric telescopic main beam mechanism, a reverse roller and an electric hoist. The mechanism and the anti-roller are connected to the main beam, the electric telescopic main beam mechanism and the anti-roller are installed on the main beam, and the electric hoist is installed on the electric telescopic main beam mechanism and the anti-roller.

As a further solution of the utility model: the main girder realizes electric expansion and contraction.

As a further solution of the utility model: the main beam, the electric telescopic main beam mechanism and the anti-roller, the electric telescopic main beam mechanism, the anti-roller and the electric hoist are all connected by anti-rollers.

Compared with the prior art, the beneficial effect of the utility model is: the utility model meets the domestic and foreign market demand, makes it have the basic function of a suspension crane, and at the same time enables the electric hoist to realize cross-regional operation, increasing the operating range of the crane, The utilization rate of the crane is improved, the purchase cost of additional handling equipment is reduced, the product handling time is shortened, and the work efficiency is improved.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1 and Figure 2, a telescopic electric suspension crane according to the embodiment of the utility model includes a cart operating mechanism, an anti-roller 1, a main beam 2, an electric telescopic main beam mechanism, an anti-roller 3, and an electric hoist 4 , the cart operating mechanism and the anti-roller 1 are connected to the main beam 2, the electric telescopic main beam mechanism and the anti-roller 3 are installed on the main beam 2, and the electric hoist 4 is installed on the electric telescopic main beam mechanism and the anti-roller 3 on.

As a further solution of the utility model: the main girder 2 realizes electric expansion and contraction.

As a further solution of the utility model: the main beam 2 and the electric telescopic main beam mechanism and the anti-roller 3, the electric telescopic main beam mechanism and the anti-roller 3 and the electric hoist 4 are all connected by an anti-roller.

Combined with Figure 1 and Figure 2, the main structure frame of the crane is composed of the cart running mechanism, anti-roller 1 and main girder 2. The crane can move forward and backward along the direction of the workshop through the cart running mechanism, and the electric telescopic main girder mechanism and anti-roller 3 can The main girder is extended or contracted to achieve cross-section operation. The electric hoist 4 can lift heavy objects and move on the main girder. When the electric hoist 4 runs to the left end, the anti-roller pushes upwards to prevent the crane from tipping and make the crane stable. run.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any minor modifications, equivalent replacements and improvements made to the above embodiments according to the technical essence of the present utility model shall be included in the Within the scope of protection of the technical solution of the utility model.
