The existing crawler vehicle climbing performance test is mainly carried out on closed inclined sections, but the test slope cannot be adjusted, resulting in the need for multiple closed sections and a large site. In addition, when climbing, when the crawler vehicle's climbing inclination angle reaches the maximum value, it is prone to slipping, which is dangerous.

[0028] Compared with the prior art, the present invention provides a climbing performance test device for an integrated transmission system of a tracked vehicle, which has the following beneficial effects:

[0029] In the present invention, the crawler vehicle is driven onto the conveyor belt for testing. During the test, the crawler vehicle and the conveyor belt are made to move relative to each other, so that the crawler vehicle remains stationary relative to the ground. A long closed road section is not required for testing. After the crawler vehicle moves onto the conveyor belt, the test assembly is connected to the rotating wheel axle of the crawler vehicle. During the test, the conveyor belt is slowly tilted by the hydraulic cylinder. At this time, the crawler vehicle remains in place through the relative movement of the transmission belt. When the transmission belt inclination angle continues to increase to the crawler vehicle test angle, the conveyor belt stops running and the crawler vehicle maintains optimal torque rotation. After the telescopic rod rotates, the pressure detection gauge value in the detection assembly continues to increase, indicating that this angle is not the maximum climbing angle of the crawler vehicle. After it increases to the set value, the conveyor belt is started to return the crawler vehicle to its original position, thereby improving the safety during the test. When the pressure detection gauge value in the detection assembly remains unchanged, it indicates that this angle is the maximum climbing angle of the crawler vehicle.

[0035] Reference Figures 1 to 4 The present invention provides a technical solution: a climbing performance test device for a tracked vehicle integrated transmission system, comprising:

[0036] A placement groove 11 is provided on the ground 1, and an avoidance groove is provided in the placement groove 11;

[0037] The side panels 2 are symmetrically arranged in the placement groove 11, and when placed horizontally, their height is flush with the ground 1, and one end of the bottom of the side panel 2 is hinged to the bottom of the placement groove 11 through a hinge shaft 6, and the side walls of the side panels 2 that are away from each other are provided with sliding grooves 21;

[0038] The conveyor belt 3 is installed between the two side plates 2, and a limit switch 5 is installed at one end thereof;

[0039] A hydraulic cylinder 4, one end of which is hinged to the side panel 2 at a position away from the hinge shaft 6, and the other end of which is hinged in the avoidance groove; and

[0040] The test assembly 7 has one end slidingly disposed in the slide groove 21 , and at least two groups of test assemblies 7 are disposed on one side plate 2 , and the other end is connected to the rotating shaft of the crawler 8 .

[0041] It should be noted that before the test, the rotational speed of the conveyor belt 3 is the same as the rotational speed of the crawler belt 8, so that the crawler vehicle can move in place on the conveyor belt 3. When the crawler vehicle reaches the optimal torque, it begins to tilt at an angle through the hydraulic cylinder 4. When tilting, the rotational speed of the conveyor belt 3 is adjusted to ensure that the crawler vehicle always runs in place. When the test angle is reached, the conveyor belt 3 stops running, thereby testing the climbing performance of the crawler vehicle.

[0042] In this embodiment, the test component 7 includes:

[0043] A detection component 71 is slidably disposed in the slide groove 21;

[0044] A telescopic rod 72, one end of which is rotatably disposed within the detection assembly 71;

[0045] A sliding post 73 is slidably disposed at the other end of the telescopic rod 72; and

[0046] The limiting assembly 74 is fixed on the sliding post 73 .

[0047] That is to say, when the conveyor belt 3 stops running, the crawler belt 8 keeps rotating at the optimal torque, and at this time, the rotation of the telescopic rod 72 and the detection component 71 are tested.

[0048] As a preferred embodiment, limit blocks 75 are fixed on both sides of the detection component 71, and limit bolts are threadedly connected to the limit blocks 75 for limiting the detection component.

[0049] As a preferred embodiment, the detection component 71 includes:

[0050] Sliding frame 711;

[0051] A rotating shaft 712 is rotatably disposed within the sliding frame 711 and fixedly connected to the telescopic rod 72;

[0052] A pressing block 713 is symmetrically fixed on the rotating shaft 712; and

[0053] The pressure detection gauge 714 is fixed in the sliding frame 711 , and a return spring 715 is provided between the pressure detection gauge 714 and the two pressing blocks 713 .

[0054] That is to say, when the telescopic rod 72 rotates, the rotating shaft 712 drives the pressing block 713 to rotate, thereby generating pressure on the pressure detection gauge 714. When this pressure continues to increase, it means that this angle is not the maximum climbing angle of the crawler vehicle, and the inclination angle of the conveyor belt 3 can be further increased. When the pressure increases to the set value, the conveyor belt 3 is started to return the crawler vehicle to its original position, thereby improving the safety during the test. When the conveyor belt 3 stops, the value of the pressure detection gauge 714 in the detection component 71 remains unchanged, indicating that this angle is the maximum climbing angle of the crawler vehicle.

[0055] As a preferred embodiment, the limiting assembly 74 includes:

[0056] A fixed frame 741, one end of which is fixed to the sliding post 73;

[0057] The limiting posts 742 are configured in six numbers and are slidably disposed on the fixing frame 741 in a circular manner;

[0058] A clamping plate 744 fixed to one end of the limiting column 742 located inside the fixing frame 741; and

[0059] The limiting spring 745 is sleeved on the limiting post 742 and is located between the fixing frame 741 and the clamping plate 744 .

[0060] As a preferred embodiment, the outer wall of the limiting column 742 is threadedly connected to the limiting plate 743 , and the limiting plate 743 fits against the outer wall of the fixing frame 741 .

[0061] As a preferred embodiment, a guide surface 746 is provided on one end of the clamping plate 744 away from the sliding column 73, and a clamping surface 747 is provided on one side of the clamping plate 744 away from the limiting column 742, and the six clamping surfaces 747 together form a hexagonal clamping space, which is convenient for clamping the nut.

[0062] Specifically, first, the crawler vehicle is driven onto the conveyor belt 3, and the limit assembly 74 is connected to the rotating shaft of the crawler belt 8. Then, the detection assembly 71 is fixed and limited by the limit block 75, so that the telescopic rod 72 remains in a vertical state. Then, the crawler belt 8 and the conveyor belt 3 are moved relative to each other, so that the crawler belt 8 runs in situ on the conveyor belt 3. When the crawler belt 8 reaches the optimal torque, the conveyor belt 3 is slowly tilted by the hydraulic cylinder 4. At this time, the crawler belt 8 is kept running in situ by the relative movement of the transmission belt 3. When the inclination angle of the transmission belt 3 continues to increase to the crawler vehicle test angle, the conveyor belt 3 stops running, and the crawler 8 continues to rotate with the optimal torque. At this time, after the telescopic rod 72 rotates, the value of the pressure detection gauge 714 in the detection assembly 71 continues to increase, indicating that this angle is not the maximum climbing angle of the crawler vehicle. When the value of the pressure detection gauge 714 in the detection assembly 71 remains unchanged, it means that this angle is the maximum climbing angle of the crawler vehicle.

[0063] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
