Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It should be understood that the description herein of specific embodiments is for purposes of illustration and explanation only and is not intended to limit the invention.
A crane according to the invention is described below with reference to the accompanying drawings.
As shown in fig. 1, in the embodiment of the present invention, a crane is provided, wherein, the crane includes a thrust mechanism 41, a super-lift weight 51 and a standing platform 101, the tail of the thrust mechanism 41 is provided with a connection pulling plate 40, the super-lift weight 51 is suspended at the tail of the thrust mechanism 41 and is provided with a super-lift weight pulling plate 50, the super-lift weight pulling plate 50 is connected with the connection pulling plate 40 and forms a pulling plate junction 60 at the tail of the thrust mechanism 41, and the standing platform 101 is arranged below the pulling plate junction 60 and is fixedly connected with the thrust mechanism 41.
The connecting pull plate 40 is a pull plate which is arranged on the thrust mechanism 41 and connected with the super-lift counterweight pull plate 50; the thrust mechanism 41 is a folding telescopic arm, the front end of the thrust mechanism 41 is connected with a crane rotary table, the tail end of the thrust mechanism 41 is connected with the super-lifting counterweight 51 and the connection pulling plate 40, wherein the crane rotary table is the rotary center of the crane, and the thrust mechanism 41 can change the distance between the super-lifting counterweight 51 and the crane rotary table through stretching, so that the moment of the super-lifting counterweight 51 to the crane can be adjusted.
The specific connection mode of the connecting pulling plate 40 and the super-lifting counterweight pulling plate 50 is as follows: the staff stands on the platform of standing, will connect arm-tie 40 and super lift counter weight arm-tie 50 coaxial coupling, and such connection working method is simpler, does not receive the place restriction moreover, after connecting arm-tie 40 and super lift counter weight arm-tie 50 and connect, thrust mechanism 41 side can be connected and move actions such as lift with super lift counter weight 51 according to the work needs.
It should be noted that the tail of the thrust mechanism 41 is suspended and the position of the connecting part 60 of the pulling plate is higher, so that a worker often needs to be lifted by a crane during the operation of connecting the pulling plate and then lies prone on the thrust mechanism 41 to perform the operation of connecting the pulling plate. The utility model provides a crane, this crane have set up the platform 101 of standing in the below of arm-tie junction 60, for the staff provides the foot ground that falls that the level was arranged, the staff can be steady safe stand accomplish on the platform 101 of standing and connect arm-tie 40 and the connection of super rising counter weight arm-tie 50, make arm-tie connection work safe high-efficient more, have not only strengthened product reliability, have improved construction safety nature, have embodied humanized design theory more.
