Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1-5, the invention provides a semi-automatic vertical crane wheel clamp, which comprises a bracket 1 and clamp claws 3 symmetrically arranged;
the two claws 3 are hinged to the bottom of the bracket 1, the hinged point of the claws 3 is arranged at the middle upper part of the claw 3, and the upper part of the claw 3 is provided with a force returning mechanism for resetting the claw 3;
the middle part of the bracket 1 is provided with a locking mechanism for locking the clamp claw 3, and the top of the bracket 1 is provided with a hanging ring 102. The two jaws 3 rotate along the support 1 to realize a clamping function, the locking of the two jaws 3 is realized through the locking mechanism, and the loosening of the two jaws 3 is realized through the force returning mechanism.
Further optimize the scheme, locking mechanism includes that vertical seting up in the spout 101 in support 1 middle part, slip setting are in the shelves round pin 2 of spout 101, and support 1 is the type structure of falling the fork, and spout 101 is seted up on two yoke arms of support 1. As shown in fig. 5, when the two jaws 3 are closed and clamped, the stop pin 2 is pressed downwards by one hand, the stop pin 2 is clamped at the middle position of the upper parts of the two jaws 3, so as to lock the jaws 3, when the jaws 3 need to be opened, the stop pin 2 is pushed upwards, and the jaws 3 are reset under the action of the return mechanism. Because the diameter of the stop pin 2 is a fixed size, the distance between the two clamp claws 3 after being locked is a fixed distance, so that the width matching of the clamp claws 3 and the width of a wheel is ensured, and the wheel is prevented from being damaged in the hoisting process.
Further optimize the scheme, shelves round pin 2 runs through spout 101 and sets up, and the bottom is equipped with back taper structure 201 in the middle of shelves round pin 2, and back taper structure 201 length and two yoke outside interval phase-matches.
