Description

Resetting device of trolley

Technical Field

The invention relates to a resetting device of a trolley.

Background

With the development of the ship manufacturing industry, the crane carried by the ship develops to large tonnage, large span and large lifting height. In practical use, once the trolley is derailed, the repairing process mainly utilizes a floating crane or a large truck crane to reset, so that the cost is high, and the shipbuilding gantry crane needs to be moved during repairing, so that the safety risk is increased.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides the resetting device of the crane trolley, which can reduce risks and repair cost, can hoist and transport the crane by utilizing the overhaul of the crane without moving the crane, and has low safety risk and low cost.

In order to achieve the purpose, the technical scheme of the invention is to design a resetting device of a trolley, which comprises a sliding trolley connected with the trolley through a support and a jack used for jacking the sliding trolley. The sliding trolley in the device consists of a support and two rubber-coated rotating wheels. When repairing, the sliding trolley can be arranged on the bracket, the lifting trolley is jacked up and put on the sliding trolley by the jack, and the lifting trolley can be reset by the chain block.

The technical scheme is that the reset device further comprises a rail lath fixedly connected to the lower surface of the trolley, and two ends of the rail lath are fixedly connected with a stop plate which extends downwards and is used for limiting the trolley to move left and right transversely to a limit position.

The further technical scheme is that the support is a jacking jig frame fixedly connected to the top end of the gantry crane main beam, and the jack is arranged at the top end of the gantry crane main beam.

The further technical scheme is that the top end of a main beam of the gantry crane is also provided with a lateral pushing device which is positioned on one side of a jack and used for laterally pushing to correct the position of the trolley.

The further technical scheme is that the number of the track laths is four, the number of the jacks is four, and one lateral pushing jack is arranged. The specific action process is as follows: resetting the sliding trolley: transporting the sliding trolley and the like to a gantry crane main beam by using a maintenance crane, transporting a tool to the upper trolley by using a lower trolley, welding four rail plates for sliding on a bottom plate of the upper trolley, and arranging stop plates at two ends, wherein 4, four 3.6m jig frames are installed, an item lifting point is reserved on the jig frames, the upper trolley is lifted by using four jacks on the jig frames, and the sliding trolley is installed on the jig frames; arranging a horizontal jacking seat, and laterally jacking by using a horizontal jack to correct the position of the upper trolley; replacing the damaged hinged support at the rigid leg side; lifting the jack again on the jig frame, dismantling the sliding trolley and enabling the upper trolley to enter the rail; and (4) dismantling all the tools and starting the recovery of the damaged part.

The further technical scheme is that an elastic component is fixedly arranged at the upper end of the jack, a bearing plate is fixedly connected above the elastic component, and anti-skid grains are arranged on the upper surface of the bearing plate.

The further technical scheme is that the bearing plate is fixedly connected to the lower surface of the trolley, the bearing plate is provided with one block, the elastic assembly comprises a plurality of springs and an annular sleeve arranged around the springs, and the bearing plate is fixedly connected with the springs and the annular sleeve at the upper ends of the four jacks. After setting up like this, four jacks can be basically not very much the progress of each jack, because the cooperation of setting up of elastic component is welded the board of accepting at the trolley lower surface, can the fast operation jack after slightly finely tune one of them two jacks can guarantee that the trolley by the jack-up is the horizontally state, then the installation dolly etc. < the advantage of the whole block such setting of accepting the board has just been embodied >.

The invention has the advantages and beneficial effects that: the risk can be reduced, the repair cost is reduced, the crane does not need to be moved, and the sliding trolley, the bracket and the like can be hoisted to the crane by utilizing the overhaul of the crane, so that the safety risk is low, and the cost is low; the four jacks can basically not consider the progress of each jack, because the arrangement of the elastic component is matched with the bearing plate welded on the lower surface of the trolley, the jacked trolley can be ensured to be in a horizontal state by slightly finely adjusting one or two jacks after the jacks are operated quickly, and then the sliding trolley is installed, and the like, the advantages of the arrangement of the whole bearing plate are reflected.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 3, the invention relates to a resetting device of a trolley, which comprises a sliding trolley 3 connected with the trolley 1 through a bracket 2 and a jack for jacking the sliding trolley 3. The resetting device also comprises a track lath 4 fixedly connected to the lower surface of the trolley 1, and two ends of the track lath 4 are fixedly connected with a stop plate 5 which extends downwards and is used for limiting the trolley 1 to move left and right transversely to a limit position. The support 2 is a jacking jig frame fixedly connected to the top end of the gantry crane main beam 6, and the jack is arranged at the top end of the gantry crane main beam 6. The top end of the gantry crane main beam 6 is also provided with a lateral pushing device 7 which is positioned at one side of the jack and used for laterally pushing 7 so as to correct the position of the crane trolley 1. The number of the track laths 4 is four, the number of the jacks is four, and the number of the lateral thrusters 7 is one. The upper end of jack is fixed and is provided with an elastic component, the upper part of the elastic component is fixedly connected with a bearing plate 8, and the upper surface of the bearing plate 8 is provided with anti-skid grains. The bearing plate 8 is fixedly connected to the lower surface of the trolley 1, the bearing plate 8 is provided with one block, the elastic component comprises a plurality of springs 9 and an annular sleeve 10 arranged around the springs 9, and the bearing plate 8 is fixedly connected with the springs 9 and the annular sleeve 10 at the upper ends of the four jacks.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
