[0034] Specifically, support 1 includes side plate 2 and bottom plate 3, side plate 2 is connected on vehicle body by bolt connection mode and is located at one side of engine, bottom plate 3 is connected with side plate 2 perpendicularly, compressor is installed on side plate 2 by bolt, improve its stability when using.Tensioning adjusting assembly is arranged at one side of side plate 2, can adjust the tightness of the belt between the pulley of compressor and the pulley of engine, ensure that the belt always maintains appropriate tension in the process of running, effectively avoid the problem such as skidding, transmission efficiency decline caused by too loose belt, also prevent the belt from being too tight to cause excessive wear on pulley and bearing, prolong the service life of belt.

[0035] When using, first, the side plate 2 of support 1 is installed to vehicle body, ensure firm installation.Then the compressor is installed on the corresponding hole position of side plate 2 by bolt, complete the preliminary fixation of compressor.Next, the belt is sleeved on the engine pulley and compressor pulley.At this time, the operator can observe the tightness of the belt, and the tightness of the belt is fine-tuned through the tensioning adjusting assembly.After adjustment, check whether the connection of each component is firm again, confirm that there is no error, start the engine, observe the running condition of air conditioner compressor and the transmission state of belt.If it is found that the tightness of the belt is not suitable, fine-tuning can be carried out again until the belt reaches the best working state.

[0036] The tensioning adjusting assembly comprises:

[0037] Adjusting plate 4, the adjusting plate 4 is arranged on the side plate 2, and a sliding hole is formed in the adjusting plate 4.

[0038] A fixing part 5 is arranged on the compressor;

[0039] A connecting piece 6 is connected with the fixing part 5 through the sliding hole.

[0040] The adjusting plate 4 is in an arc structure.

[0041] Specifically, the adjusting plate 4 is installed on the side plate 2 and is in an arc structure, so that the sliding hole is arranged along the arc, the fixing part 5 is arranged on the compressor, the fixing part 5 is provided with a connecting hole matched with the connecting piece 6, and the connecting piece 6 can be stably connected with the fixing part 5 through the sliding hole. When the compressor is located at the bottom end, the bottom of the compressor is located on the bottom plate 3, and the connecting piece 6 is a screw rod and a nut.

[0042] In use, when it is found that the loader air conditioner compressor belt is loose, the operator first loosens the nut of the connecting piece 6, so that the compressor is in an adjustable state. Then, according to the degree of looseness of the belt, the compressor is pushed or pulled along the arc sliding hole of the adjusting plate 4, at this time, the fixing part 5 and the connecting piece 6 cooperate to drive the compressor to move along the arc track, and gradually tighten the belt.

[0043] The tensioning and adjusting assembly comprises:

[0044] A fixing plate 7 is arranged on one side of the side plate 2;

[0045] An adjusting part 8 is arranged on the fixing plate 7;

[0046] An adjusting wheel 9 is arranged on the adjusting part 8, the adjusting part 8 can drive the adjusting wheel 9 to move on the fixing plate 7, and the adjusting wheel 9 is located between the pulley of the compressor and the pulley of the engine.

[0047] Specifically, the fixed plate 7 is arranged on one side of the side plate 2 and has an L-shaped structure. The adjusting part 8 is mounted on the fixed plate 7 and used for adjusting the position of the adjusting wheel 9 on the fixed plate 7. The adjusting wheel 9 is located between the pulley of the compressor and the pulley of the engine. The adjusting wheel 9 has a high-strength metal hub, and the surface of the hub is wrapped with a high-elasticity and wear-resistant rubber layer. Anti-skid lines are arranged on the rubber layer, which can increase the friction between the adjusting wheel 9 and the belt, prevent the belt from slipping, and also play a buffering role to reduce the impact and wear of the belt during operation. The adjusting wheel 9 is connected with the adjusting part 8 through a bearing, which ensures that the adjusting wheel 9 can rotate flexibly and reduces the running resistance. During the adjusting process, the adjusting part 8 drives the adjusting wheel 9 to move on the fixed plate 7. When the adjusting wheel 9 moves towards the belt, it will exert greater pressure on the belt and make the belt tight. Conversely, when the adjusting wheel 9 moves away from the belt, the tension of the belt decreases. In this way, the operator can accurately adjust the tightness of the belt according to the actual needs, so that the belt can always maintain appropriate tension during operation, effectively avoiding problems such as slipping and reduced transmission efficiency caused by loose belt.

[0048] The adjusting part 8 comprises:

[0049] The connecting rod 10 is connected with the shaft center of the adjusting wheel 9 through a limiting hole arranged on the fixed plate 7.

[0050] The adjusting rod 11 is arranged between the fixed plate 7 and the bottom plate 3, and is connected with the connecting rod 10. Rotating the adjusting rod 11 can drive the connecting rod 10 to slide in the limiting hole.

[0051] The adjusting rod 11 is a threaded rod, and the adjusting rod 11 is threadedly connected with the connecting rod 10.

[0052] Specifically, the connecting rod 10 penetrates through the limiting hole on the fixed plate 7 and is stably connected with the shaft center of the adjusting wheel 9. The adjusting rod 11 is arranged between the fixed plate 7 and the bottom plate 3 and used for driving the connecting rod 10 to move. The adjusting rod 11 usually has a screw structure, one end of which is threadedly connected with the connecting rod 10, so that the rotating motion can be converted into the linear motion of the connecting rod 10 when the adjusting rod 11 is rotated. The other end of the adjusting rod 11 extends to a position convenient for the operator to operate and is provided with an adjusting handle. The adjusting rod 11 is supported by a bearing seat or a support sleeve between the fixed plate 7 and the bottom plate 3, so that the adjusting rod 11 can remain stable during rotation and the adjustment error caused by shaking can be reduced. When the operator rotates the adjusting rod 11, the rotation of the adjusting rod 11 will drive the connecting rod 10 to slide linearly in the limiting hole due to the connection relationship between the adjusting rod 11 and the connecting rod 10. Thus, the tightness of the belt can be accurately adjusted.

[0053] The adjusting part 8 further comprises a positioning rod 12, which is arranged between the fixing plate 7 and the bottom plate 3 through the connecting rod 10, and is located on one side of the adjusting rod 11.

[0054] Specifically, the positioning rod 12 is arranged between the fixing plate 7 and the bottom plate 3 through the connecting rod 10, and is used for limiting the adjusting rod 11 in movement, and the adjusting rod 11 can move up and down along the axis of the positioning rod 12 when the adjusting rod 11 is rotated.

[0055] A plurality of rib plates 13 are arranged between the bottom plate 3 and the side plate 2.

[0056] Specifically, the rib plate 13 is arranged on the bottom plate 3 and the side plate 2 on both sides, so as to enhance the connecting strength of the bottom plate 3 and the side plate 2 and improve the fixing performance of supporting the compressor.

[0057] A plurality of mounting holes 14 are formed in the side plate 2.

[0058] Specifically, the mounting hole 14 is arranged to facilitate the mounting of the side plate 2 on the vehicle body.

[0059] The side plate 2 is provided with a fixing seat, and the fixing seat is used for fixing the compressor.
