Description

A bridge-type lifting compound device for vehicle body transportation

technical field

The present invention relates to a bridge-type hoisting type used for car body transportation in order to facilitate the overturning and maintenance of the car body and the automatic transportation in the workshop during the production, maintenance and transportation of the railway vehicle body. Composite device. It belongs to the technical field of conveying equipment.

Background technique

Existing train body overhaul is basically the original manual overhaul of bench type. In this state, the overhauling of the train car body, the dismantling, dismounting, assembly and welding repair of all parts on the car body are all completed at the same position. The original manual inspection of the table type obviously cannot guarantee the quality of its inspection. The original manual maintenance of the bench type is also unable to realize the flow operation, so that the work efficiency cannot be improved. On the contrary, there is a lot of waste of material and manpower. Not only is it inefficient, but it is also costly. In the original manual maintenance of the bench type, unsafe incidents often occur during the actual operation process. The occurrence of accidents will not only cause shutdowns, but also cause injuries to operators.

Contents of the invention

The object of the present invention is to address the above-mentioned defects and to propose a bridge-type lifting compound device for vehicle body transportation based on the fact that the vehicle body is heavy and huge. The crane is used for hoisting, and according to the multi-degrees of freedom of this specific crane, it is transported in all directions, and in the large-scale transportation field, an automatic assembly line production environment is realized. And can effectively overcome the defects such as inefficiency existing in the maintenance of the train car body in the prior art, not easy to turn over and the like.

The technical solution of the present invention: it is characterized in that the track on the crane frame is connected to the main girder in the crane frame, and the bridge-type hoisting crane is installed on the track of the crane frame through its running wheels, and the bridge-type hoist The electric hoist on the crane is installed on the main girder of the bridge crane, and the sliding suspension plate is installed on the main girder in the crane frame with a rolling connection; the bridge crane is composed of two main girders and two beams welded , the two ends of the beam are respectively equipped with a bearing box and a running wheel, the beam and the bearing box are connected by bolts, the main beam has an I-shaped steel track, and the four hoists on the bridge crane are installed on the two tracks.

The structure of the crane frame is that the crossbeam and the main beam are welded together, and the bearing box is used to install the running wheels.

The above scheme is to install the frame of the conveying crane on the corbel of the factory building, use the track of the corbel to make the frame move longitudinally, and then use the track of the main girder on the frame to use the rail and rollers for the bridge crane It is installed on the main beam of the frame to carry out lateral movement. Four hoists are installed on the main beam of the hoisting crane, which can lift the car body at four points. A sliding hanging plate is installed on the track at the installation position of the hoisting crane, and an extended hoist can be installed on it. Special equipment and as a guard plate after the car body is hoisted.

The advantages of the present invention: use the special crane structure to solve the limitation of the degree of freedom of the traditional crane, in the field of transporting the train car body, the equipment can be installed in the train manufacturing, maintenance and other workshops, and the special crane can be used to transport, The extension of the sliding hanging plate forms a three-dimensional conveying field of a series of spaces, forming an automated assembly line, which improves efficiency and saves manpower.

Description of drawings

Accompanying drawing 1 is the structure schematic diagram of bridge type lifting compound device.

Among the figure, 1 is a running wheel, 2 is a beam, 3 is a main girder, 4 is a track, 5 is a bridge crane, 6 is a hoist on the crane, and 7 is a sliding hanging plate.

Detailed ways

With reference to accompanying drawing 1, its structure is that the rail 4 on the crane frame is welded and connected on the main girder 3 in the crane frame, and the bridge-type hoisting crane 5 is installed on the rail 4 of the crane frame by its running wheels, It can move freely, the electric hoist 6 on the bridge crane 5 is installed on the main beam 3 of the bridge crane 5, the sliding suspension plate 7 is connected by rolling and installed on the main beam 3 in the crane frame, the whole crane The plate can cover the hoisting range of the overhead traveling crane 5 . The structure of the crown block frame is that the beam 2 and the main beam 3 are welded together, and the running wheel 1 is installed with a bearing box.

The structure of the bridge crane 5 is composed of two main girders and two crossbeams welded together. The two ends of the crossbeam are respectively equipped with a bearing box and a running wheel. The bearing box and the crossbeam are connected by bolts. It is connected in a coordinated form. When the traveling wheel walks on the track, it drives the beam and the main beam to move forward. The main beam has an I-shaped steel track, and the four hoists 6 of the bridge crane 5 are installed on the two tracks. Hoisting, the way of wire rope hoisting, lifting heavy objects.

The hoist 6 on the bridge crane crane is composed of a reel, a wire rope, a traveling wheel and a traveling lifting motor. The reel is connected with the steel wire rope. When working, the walking lifting motor drives the reel to rotate, and the telescopic steel wire rope can lift heavy objects.

Described sliding suspension plate 7 is the steel plate that a welding forms, and two ends are equipped with traveling wheel, can slide on track, and steel plate can bear heavy object, and certain special machine equipment can be installed.

During work, when the car body needs to be lifted, the sliding suspension plate is first rolled away by the rollers on it to leave the lifting position, and the four hoists on the bridge crane use steel wire ropes to lift the four points of the car body. , the sliding plate moves back, and the crane can move the car body horizontally or vertically to the position that needs to be transported according to its multiple degrees of freedom.
