Abstract
The utility model relates to an adjustable car coupler lifting device which comprises a case body and car coupler bracket forks arranged below the case body. A car coupler bracket guide device and a guide screw device are arranged on the case body. The car coupler bracket forks are at least two in number, one is connected with the guide screw device through the car coupler bracket guide device and the other is fixed on the case body through a bracket spacer plate. The distance between the car coupler bracket forks of the adjustable car coupler lifting device can be adjusted through the guide screw device when removing or installing the car coupler, thus ensuring that the car coupler is free from the influence of a handle of the car coupler during the removal or installing process and the car coupler can be removed or installed conveniently. The adjustable car coupler lifting device adopts the car coupler bracket guide device to guide the guide screw device to adjust the distance between the forks, thus preventing the fork from inclining during the adjusting process.
Description
Technical field
The utility model relates to a kind of hook dismounting equipment, specifically, relates to a kind of device of lifting of lifting hitch when being used for dismounting.
Background technology
At present, the hitch of runing the various motor train unit of CRH is tight lock coupler, and the hitch of every kind of vehicle is divided into company's wagon coupling trip of a car automatic car coupler and middle car.The profile of various vehicle hitches, highly, the connection mode of installation dimension and hitch and car body is all inequality; The heaviest about 800kg of car hitch, middle hitch weight is between 200kg～300kg, and hitch is installed in car end inside.Above factor has caused relatively difficulty of hook dismounting.Therefore, in the car inspection and maintenance process, the dismounting of hitch and installation need carry out dismounting with the disassemblerassembler of special use, this lifts the hitch of the different various motor train unit of CRH with regard to needing the different devices of lifting, but existing lifting in the device because the hitch of CRH1 EMUs is provided with a handle, so when dismounting is lifted, bother very much, thus just need a kind of can easy disassembly lift lift device.
The utility model content
The purpose of this utility model is to lift in the hook dismounting process at existing CRH1 EMUs the deficiency of dismounting trouble, provides a kind of scalable hitch carriage pallet fork spacing, hook dismounting to lift easily the novel adjustable hitch and has lifted device.
The technical solution of the utility model is: a kind of adjustable hitch is lifted device, comprises casing and the hitch carriage pallet fork that is arranged on the casing below, and described casing is provided with a hitch carriage guide piece and a feed screw apparatus; Described hitch carriage pallet fork is provided with two at least, and one of them hitch is lifted pallet fork and is connected with feed screw apparatus by hitch carriage guide piece, and another hitch carriage pallet fork is fixed on the casing by bracket plate;
Preferably, described hitch carriage guide piece comprises hitch carriage guide groove and is installed on the interior orienting lug of guide groove that guide groove is by being bolted on the casing;
Preferably, described feed screw apparatus comprises leading screw handwheel and leading screw, and an end of leading screw is connected with the leading screw handwheel by the leading screw pressing plate, and the other end is connected with orienting lug by the carriage nut;
Preferably, the rear wall of described casing upper end is respectively arranged with a hook with two corresponding positions of hitch carriage pallet fork, and the sidewall rear end of casing is provided with a pointer;
Preferably, the corresponding position of hitch gib head with want dismounting on the front side wall of described casing is provided with two circular holes, and one of them circular hole arranged outside has an outstanding extension edge;
Preferably, described hitch carriage pallet fork is a crank hitch carriage pallet fork and a staight shank hitch carriage pallet fork, crank hitch carriage pallet fork by screw retention on orienting lug;
Preferably, described hitch carriage pallet fork is provided with a hitch backing plate.
The beneficial effects of the utility model are: the utility model can be when carrying out dismounting by feed screw apparatus, regulate the distance between the hitch carriage pallet fork, thereby be not subjected to the influence of hitch handle when having guaranteed dismounting, easy disassembly, and adopting hitch carriage guide piece is that feed screw apparatus is regulated the distance guiding between the pallet fork, has prevented to occur in the mediation process pallet fork bevelled phenomenon.
