The marks in the figure: 1. the device comprises a hanging ring, 2, a pull rod, 3, a pin shaft, 4, a positioning block, 401, a stop surface, 5, a spring, 6, a half-shaft shell, 601 and an opening edge.
Detailed Description
The utility model is described in further detail below with reference to the drawings and examples, which are not intended to be limiting.
As shown in fig. 1 and 2, a lifting appliance for lifting a half-shaft shell comprises a pull rod 2 and a positioning block 4, wherein a lifting ring 1 is arranged at the upper end of the pull rod 2 and is used for being connected with lifting equipment such as a crane, the lower end of the pull rod 2 is rotationally connected with the positioning block 4 through a pin shaft 3, a fixed seat is arranged on a rod body of the pull rod 2, one side of the positioning block 4 is provided with a movable seat, one end of a spring 5 is connected with the fixed seat, the other end of the spring 5 is connected with the movable seat, when the positioning block 4 is not subjected to external force, under the action of the elastic force of the spring 5, one end of the movable seat, which is arranged on the positioning block 4, is pulled upwards to be close to the pull rod 2, so that the positioning block 4 forms an inclined posture, at the moment, the positioning block 4 forms an acute angle with the pull rod 2, and the position of the positioning block 4 is the initial position of the positioning block 4.
When the positioning block 4 is in the initial position, the horizontal distance between the lower end and the upper end of the positioning block 4 is smaller than the inner diameter of the small end orifice of the half-shaft shell 6, so that the positioning block 4 can extend into the half-shaft shell 6; the size of the positioning block 4 in the transverse direction or the longitudinal direction is larger than the inner diameter of the small end hole of the half-shaft shell 6, so that the positioning block 4 can be clamped on the inner side of the opening edge 601 of the hole of the half-shaft shell 6, and the hoisting of the half-shaft shell 6 is facilitated.
In order to further improve the reliability of hoisting the half-axle housing, the edge of the positioning block 4 is provided with a stop surface 401 which can be clamped inside the opening edge 601 of the half-axle housing 6, and the stop surface 401 is a step surface.
