Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-2:
a quick joint of an excavator comprises support plates 1 which are horizontally and symmetrically arranged, pin bases 2 are obliquely connected to the front ends of the support plates 1 upwards, and the lower sides of the pin bases 2 of the support plates 1 are connected into a whole through clamping heads 3; the rear end of the support plate 1 is connected through a pin column A11, the middle part of the support plate is connected through a pin column B12, a pin hole A21 and a pin hole B22 are arranged on the pin seat 2 at intervals, two ends of the bottom side of the clamping head 3 are respectively connected with a shovel head 4, and the shovel head 4 and the outer side of the clamping head 3 are connected into a whole through a convex elliptical reinforcing plate 5.
The working principle is as follows: when in use, the pin shaft penetrates through the pin A11 and the pin B12 and is fixedly connected with the forearm of the excavator; after the chuck 3 is operated to be clamped into a clamping block of equipment, automatic positioning is completed, then a pin shaft penetrates through the pin hole A21 and the pin hole B22, and the equipment and the quick connector are fixed, and the quick connector and the small arm part of the excavator are not detached in the process of replacing the equipment (the prior art is adopted, and therefore the description is omitted).
The chuck 3 part of the utility model is solid, the chuck 3 is transversely connected with the support plates 1 at two sides, the upper side and the lower side of the chuck 3 can bear great torque, the root part of the chuck 3 is prevented from deforming under the action of the torque, and the downward deflection is caused, so that the positioning during installation is influenced, the length required by the positioning is ensured by the arrangement of the shovel head 4, the total weight is greatly reduced, the elliptic reinforcing plate 5 can play a role of traction, and the direct torsional force to the root part of the chuck 3 is reduced. To further provide strong support to the root of cartridge 3, a reinforcing bar a6 may be fixed tangentially to the profile of cartridge 3 at its rear medial portion, reinforcing bar a6 being connected to pin B12, pin a11 being generally the thickest, but reinforcing bar a6 not being directly connected to pin a11, so that reinforcing bar a6 is exposed at the bottom of support plate 1, affecting the operation of the device, so that cushioning is provided by pin B12, and pin a11 providing final support via reinforcing bar B7
The moment applied to the connecting line of the pin hole A21 and the pin hole B22 is large during operation, and the 8-shaped reinforcing plate 23 for connecting the pin hole A21 and the pin hole B22 is arranged on the outer side of the pin seat 2 on the premise of not thickening the support plate 1, so that the purpose of reinforcement is achieved.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
