Problems solved by technology

The measurement of unloading parameters is performed manually when the wheel loader remains in the unloading state, which is inefficient and cannot keep up with the needs of the rapid development of enterprises. At the same time, the measurement accuracy is not high, the operation is cumbersome, and it is also interfered by human factors.

Embodiment 1

[0036] Such as figure 1 As shown, the loader unloading parameter test device includes a power source 2, a transmission system, a base plate 4, a longitudinal slide rail 7, a sliding table 8, and a distance measuring sensor 9; the power source 2 passes through the transmission system and the sliding table 8 connection, the sliding workbench 8 is installed on the longitudinal slide rail 7 through the slider, and can perform linear motion on the longitudinal slide rail 7 under the action of the power source 2 and the transmission system; the sliding workbench 8 includes The bracket 803 on it is vertically installed on the distance measuring sensor 9 on the bracket 803 .

[0037] The power source 2 is a stepping motor with an encoder, and the displacement of the workbench from the origin switch at this time can be accurately determined by the number of steps of the stepping motor recorded by the encoder.

[0038] The extension shaft of the power source 2 is equipped with a synchr...

Embodiment 2

[0045] Loader unloading parameter testing device The process of testing loader unloading parameters is as follows:

[0046]A. The loader unloading parameter testing device is placed horizontally on the test table 10. A reference plane 11 is installed on the horizontal foundation at one end of the loader unloading parameter testing device near the origin switch 3. The longitudinal direction of the loader unloading parameter testing device is in phase with the reference plane 11. Vertical, the distance from the origin switch 3 of the loader unloading parameter test device to the reference plane 11 is a definite value;

[0047] B. Park the two wheels of the front axle of the wheel loader or the front end of the crawler loader frame at a position tangent to the reference plane 11, and at the same time, the bucket edge is located in the testable area of ​​the loader unloading parameter test device, and lift the loader Move the arm to the highest point, and keep the unloading angle ...

Abstract

The invention aims to provide a loading machine unloading parameter testing device and method. The loading machine unloading parameter testing device comprises a power source, a transmission system, a base board, a longitudinal sliding rail, a sliding movable workbench and a distance-measuring sensor. The sliding movable workbench is arranged on the longitudinal sliding rail through a sliding block and can carry out linear motion on the longitudinal sliding rail. The sliding movable workbench comprises a support arranged on the workbench, and the distance-measuring sensor is arranged on the support vertically. According to the loading machine unloading parameter testing method, a driving device is used for driving the workbench to move, the lowest point of the bucket lip of a loading machine is found through the distance-measuring sensor arranged on the workbench, the vertical distance between the lowest point of the bucket lip of the loading machine and the distance-measuring sensor is tested out, and the unloading height of the loading machine is further obtained, and the unloading distance of the loading machine is measured through the moving distance of the workbench at the same time. The loading machine parameter testing device and method can measure loading machine unloading parameters simply, rapidly and efficiently, can improve loading machine testing efficiency greatly, overcomes the influence of manual factors, and has a broad application range.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a loader unloading parameter testing device and method. Background technique [0002] The unloading height of the loader refers to the vertical distance from the horizontal ground to the lowest point of the bucket edge when the boom is at the highest position and the bucket unloading angle is 45°. If the unloading angle is less than 45 degrees, the unloading angle shall be indicated. The unloading distance of the loader refers to the horizontal distance from the frontmost point of the loader body (including the tire or frame) to the bucket edge when the boom is at the highest position and the bucket unloading angle is 45°. The unloading height is to avoid interference between the lowest point of the bucket edge of the loader and the highest point of the load during loading and unloading; the unloading distance is to prevent the front wheels of the wheel loader from reaching the lowest p...
