During the assembly process, assembly personnel are difficult to operate, the safety cannot be guaranteed, the assembly efficiency is low, and the surface of a product is easy to collide with, so that the assembly quality of the product is affected.
At present, no better assembly platform device is provided for solving the assembly process of the large-caliber shell product, and therefore, the assembly platform device with the adjustable lifting height is provided for solving the problems.
Disclosure of utility model
The utility model aims to solve the requirement of vertical assembly of a large-caliber shell product and provides a lifting platform for vertical assembly of a large-caliber shell.
The utility model aims at realizing the following technical scheme:
The utility model relates to a lifting platform for vertically assembling a large-caliber shell, which comprises a support frame body, a horizontal support connected with the support frame body through a vertical guide rail, and a lifting mechanism for driving the horizontal support to vertically move;
The lifting mechanism comprises a chain, a fixed chain wheel group, a movable chain wheel and a telescopic oil cylinder;
The telescopic oil cylinder and the fixed chain wheel group are both fixed at the upper end of the support frame body, a telescopic rod of the telescopic oil cylinder extends downwards and vertically, the front end of the telescopic rod of the telescopic oil cylinder is rotationally connected with the movable chain wheel, and the rotation plane of the movable chain wheel is parallel to the extending direction of the telescopic rod; one end of the chain is fixed with the support frame body, and the other end of the chain sequentially bypasses the movable chain wheel and the fixed chain wheel group and is fixed with the horizontal support; when the telescopic rod of the telescopic oil cylinder stretches, the chain is stretched, so that the horizontal support vertically moves along the vertical guide rail.
The middle part of the horizontal support is provided with an assembly hole, and the lower end of the shell product can be assembled from the lower part of the horizontal support.
The upper plate surface of the horizontal support is rotationally connected with a supporting ring through a bearing, and the supporting ring is used for supporting the shell product to realize the rotational support of the shell product.
The horizontal support is connected with a horizontal positioning pin through a positioning sleeve, a vertical distribution positioning pin jack is arranged on the support frame body, and when the horizontal support moves vertically to any positioning pin jack position, the horizontal positioning pin is inserted into the positioning pin jack, so that the vertical movement position of the horizontal support is locked.
The beneficial effects are that:
The lifting platform can be adjusted at any height, assembly parts on the inner shape and the outer shape can be taken into consideration during product assembly, the assembly difficulty is reduced, the assembly safety is ensured, the assembly efficiency can be effectively improved, the manufacturing cost and the maintenance cost are low, and the lifting platform can be widely applied to the assembly process of various large-caliber shells.
