Detailed Description

The present invention will be further described with reference to the accompanying drawings.

An electric tractor as shown in figures 1 to 5 comprises a piling car body 1, a lifting frame 2 and a connecting arm 3.

The rear end of piling car automobile body 1 is fixed with hydro-cylinder 20, the both sides of hydro-cylinder 20 are provided with spout 21, the both sides of crane 2 are provided with gyro wheel 22, gyro wheel 22 sliding connection is in spout 21, the flexible end of hydro-cylinder 20 is connected with crane 2 through the chain for crane 2 and piling car automobile body 1 upper and lower sliding connection.

The connecting arm 3 is arranged between two pins 23 of the stacking car body 1. One end of the connecting arm 3 is hinged with the lifting frame 2 through a flange, and the other end of the connecting arm 3 is connected with a hook column 4. The hooking stems 4 act as traction means. In order to ensure the strength of the connecting arm 3, the connecting arm 3 comprises a circular arc section 5 and a horizontal section 6 connected with the tail end of the circular arc section. The upper surface of the circular arc section 5 is circular arc-shaped, and the upper surface of the horizontal section 6 is horizontal. The hooking stem 4 is connected to the upper surface of the horizontal segment 6. The upper surface of the hook column 4 is provided with an arc surface with a guiding function.

The hooking stem 4 comprises a body 7 and a sleeve 8, the sleeve 8 having a series of different diameters. The body 7 is fixedly connected with the connecting arm 3, and the sleeve 8 is covered and connected with the outer part of the body 7; the cylindrical surface of the body 7 is provided with a fold line-shaped groove 9, the inner wall of the sleeve 8 is provided with a cylindrical pin 10, and the cylindrical pin 10 is inserted into the groove 9. May be based on the size of the bore of the device to be towed. Sleeve 8 of different diameters is selected for use to avoid drawing the hole and not of uniform size with the hook post diameter, make draw gear rock with the hook post bump and destroy hook post 4. The fold-line-shaped groove 9 is matched and connected with the cylindrical pin 10, so that the sleeve 8 and the body 7 are axially fixed, and the condition that one end of the sleeve 8, which is separated from the connecting arm 3, and the body 7 are hinged with the lifting frame 2 can be avoided; a first flange 11 and a second flange 12 are arranged on one side of the lifting frame 2 at intervals along the vertical direction, the first flange 11 is provided with a first connecting hole 13, the second flange 12 is provided with a second connecting hole 14, a third flange 15 is arranged on one side of the connecting arm 3, and the third flange 15 is provided with a third connecting hole 16; the third flange 15 is disposed between the first flange 11 and the second flange 12, and the first connecting hole 13, the third connecting hole 16, and the second connecting hole 14 are opposite up and down and connected with a fixing pin 17. The inner surfaces of the first and
