Detailed Description
The invention is further described with reference to the following figures and examples.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. Accordingly, the particular details set forth are merely exemplary, and the particular details may be varied from the spirit and scope of the present invention and still be considered within the spirit and scope of the present invention.
As shown in fig. 1 and 2, the present embodiment provides a wheel type encoder for a tire crane, including a fixed bracket 1, an upper portion of the fixed bracket 1 is installed on at least one side 10 of legs on two sides of a cart, in a specific implementation, the fixed bracket 1 may be installed on a left side of the legs on two sides of the cart, or on a right side of the legs on two sides of the cart, or on the left side and the right side of the legs on two sides of the cart, a lower portion of the fixed bracket 1 is connected to a top end of an inclined bracket 3 through a first rotating shaft 2, a bottom end of the inclined bracket 3 is connected to a wheel 5 through a second rotating shaft 4, and an encoder 6 is fixed on the wheel 5.
In a specific implementation, an elastic member 7 is fixed between the bottom end of the fixed bracket 1 and the middle part of the inclined bracket 3, and the elastic member 7 may be a spring. The elastic member 7 can be extended and contracted by an external force to provide a force support to the wheel 5. One end of the elastic piece 7 is fixed with the bottom end of the fixed support 1, and the other end of the elastic piece is fixed with the middle part of the inclined support 3.
Moreover, the wheel type encoder further comprises an electric telescopic rod 8 and a connecting piece 9, wherein the electric telescopic rod 8 is installed on at least one side 10 of legs on two sides of the cart, and the electric telescopic rod 8 is connected with the inclined bracket 3 through the connecting piece 9.
