Description

Technical Field

[0001] This utility model relates to the field of loaders, and in particular to a multi-functional counterweight device for loaders. Background Technology

[0002] As a type of engineering machinery widely used in fields such as engineering construction and transportation, the main function of loaders is to transport and load various materials such as sand, gravel and coal. In actual working scenarios, when loaders perform heavy-load tasks or are in working environments with rugged terrain, their stability is easily reduced due to changes in their center of gravity distribution. Therefore, loaders are usually equipped with counterweight devices.

[0003] A search revealed Chinese Patent Publication No. CN222025157U, which discloses a multi-functional counterweight device for loaders. This utility model includes an adjustment mechanism comprising a housing. A groove is formed at the top of the housing, and a tube is slidably connected inside the groove. Two symmetrical L-shaped blocks are fixed to the outer wall of the tube near the top, and each L-shaped block has a first cylindrical hole at its top. In this utility model, by setting the adjustment mechanism, the position of the tube can be adjusted to accommodate more counterweight blocks within the housing. This avoids the situation where the housing is already full and still doesn't meet work requirements, necessitating the replacement with a larger housing or adding an additional housing, thus increasing the workload for workers. This improves both the effectiveness and efficiency of the loader's counterweight device.

[0004] While the aforementioned technologies improve both the effectiveness and efficiency of the loader's counterweight device, the device is fixedly installed on the loader using expansion bolts. This makes it impossible to dynamically adapt to changes in the loader's center of gravity under different working conditions, requiring the addition or removal of counterweights, which reduces the loader's working efficiency. Therefore, a multi-functional counterweight device for loaders is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-functional counterweight device for loaders, which aims to improve the problem in the prior art that "it requires manual addition or reduction of counterweight blocks, thereby reducing the working efficiency of the loader".

The right side of the fixing sleeve slides on the inner wall of the connector. The connector and the fixing sleeve are elastically connected by a compression spring. The right side of the connector is inserted into the inner wall of the moving block.

[0009] As a further description of the above technical solution:

Detailed implementation manner

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Refer to Figure 1 - Figure 3 As shown in the figure, an embodiment provided by the present invention: A multi-functional counterweight device for a loader includes a mounting plate 1 for fixing the counterweight device at a corresponding position of the loader. A support member 2 is fixedly connected to the upper part of the mounting plate 1, providing support and guidance for the moving block 3, enabling the moving block 3 to slide smoothly on its outer side, thereby driving the counterweight box 4 to adjust its position to meet the counterweight requirements of the loader under different working conditions. The moving block 3 is slidably connected to the outer side of the support member 2, carrying the counterweight box 4. Through cooperation with the adjustment mechanism, the position of the counterweight box 4 in the horizontal direction is adjusted to accurately adjust the counterweight position according to the actual working state of the loader. A counterweight box 4 is provided on the upper part of the moving block 3 for accommodating the counterweight 7. A cover 5 is inserted into the right side of the counterweight box 4, which can be inserted from top to bottom to block the opening of the counterweight box 4, preventing the counterweight 7 from accidentally sliding out during the operation of the loader and ensuring the operation safety. A slide rod 8 is fixedly connected to the inner wall of the counterweight box 4, providing stable support and sliding guidance for the counterweight 7.

[0036] Refer to Figure 2 - Figure 4 As shown in the figure, a counterweight 7 is provided on the outer side of the slide rod 8. By increasing or decreasing the counterweight 7 in the counterweight box 4, the center of gravity and weight distribution of the entire device are changed to adapt to different operation tasks of the loader. An adjustment mechanism is provided on the inner wall of the moving block 3. The adjustment mechanism includes an adjustment component and a limiting component. The adjustment component includes a limiting groove 61, which is set in the shape of "丰字型" (it should be noted that this shape description needs to be further clarified according to the actual situation, and it may be a specific Chinese character shape) to provide an insertion position for the limiting block 62. The limiting groove 61 is贯穿 opened on the upper part of the mounting plate 1. The limiting block 62 is slidably connected to the inner wall of the moving block 3. By inserting into the inner wall of the limiting groove 61, it plays a role in fixing the moving block 3 and the mounting plate 1. The limiting block 62 slides on the inner wall of the limiting groove 61, and a guide groove 63 is贯穿 opened on the inner wall of the limiting block 62.

[0037] Furthermore, the guide groove 63 is inclined, and the tilt angle of the guide groove 63 is used to convert the rotational motion of the threaded rod 65 into the linear sliding of the limiting block 62 in the limiting groove 61, thereby positioning the moving block 3. The inner wall of the guide groove 63 is slidably connected to the connector 64, which serves as an intermediate component connecting the limiting block 62 and the threaded rod 65, and transmits the threaded transmission of the threaded rod 65 to the limiting block 62. The connector 64 is slidably connected to the inner wall of the moving block 3, and the inner wall of the moving block 3 is rotatably connected to the threaded rod 65. The outer side of the threaded rod 65 is threadedly connected to the inner wall of the connector 64. Through the threaded connection with the connector 64, the rotational motion is converted into linear motion, driving the limiting block 62 to move, thereby realizing the position adjustment of the moving block 3 and the counterweight box 4.

[0038] Reference Figure 3 - Figure 5 The limiting component includes a connector 66, which is slidably connected to the left side of the threaded rod 65. The connector 66 has a protrusion on its inner side and slides on the inner wall of the left side of the threaded rod 65, allowing the connector 66 to rotate with the threaded rod 65. The right side of the connector 66 is toothed and can be inserted into the inner wall of the moving block 3 to limit the threaded rod 65. A fixing sleeve 68 is fixedly connected to the left side of the threaded rod 65 to provide support and positioning for the compression spring 67, ensuring that the compression spring 67 maintains stable elastic deformation during normal operation. The right side of the fixing sleeve 68 slides on the inner wall of the connector 66. The connector 66 and the fixing sleeve 68 are elastically connected through the compression spring 67. The right side of the connector 66 is inserted into the inner wall of the moving block 3 to maintain the limiting function of the connector 66 and to assist in stabilizing the threaded rod 65 during operation, preventing unnecessary displacement or shaking.

[0039] Reference Figure 6 and Figure 7 The lower part of the cover 5 is provided with a connecting component, which includes a limiting rod 51. The limiting rod 51 is slidably connected to the lower inner wall of the cover 5. The right side of the moving block 3 has an insertion hole 53. The limiting rod 51 is inserted into the inner wall of the insertion hole 53. The limiting rod 51 cooperates with the insertion hole 53 on the moving block 3. Under normal circumstances, the cover 5 can be firmly fixed on the counterweight box 4. When it is necessary to remove or install the counterweight 7, pulling the limiting rod 51 can release the limitation on the cover 5, which is convenient for operation. The outer right side of the limiting rod 51 is elastically connected to the inner wall of the cover 5 through a return spring 52. The return spring 52 provides elastic force to the limiting rod 51, thereby maintaining the insertion state of the limiting rod 51 and the insertion hole 53.

[0040] Reference Figure 6 and Figure 8The inner wall of the slide rod 8 is provided with a stabilizing component, which includes a lead screw 81 for driving the push plate 82 to move. The lead screw 81 is rotatably connected to the counterweight box 4 and the inner wall of the slide rod 8. The push plate 82 is slidably connected to the outer side of the slide rod 8. Under the drive of the lead screw 81, the counterweight 7 can be squeezed and fixed to prevent the counterweight 7 from shaking. The outer side of the lead screw 81 is threadedly connected to the inner wall of the push plate 82. A rubber pad is provided on the right side of the push plate 82 to increase the friction between it and the counterweight 7. A crank is provided on the left side of the lead screw 81 and the left side of the threaded rod 65, providing the operator with a point of force for manual operation, making it convenient for the operator to rotate the lead screw 81 and the threaded rod 65.

[0041] Working principle: When it is necessary to adjust the position of the counterweight box 4 to adapt to the counterweight requirements of different working conditions of the loader, first pull the plug 66 to make it move to the left against the elastic force of the compression spring 67, thereby releasing the plug-in limit between the right toothed part of the plug 66 and the inner wall of the moving block 3. At this time, rotate the threaded rod 65. Since the threaded rod 65 and the connecting piece 64 are threadedly connected, and the connecting piece 64 is restricted by the inner wall of the moving block 3 to slide in a straight line, under the action of the guide groove 63 inclined in the inner wall of the limiting block 62, the rotational motion of the threaded rod 65 is converted into the sliding of the connecting piece 64 in the guide groove 63 and the linear sliding of the limiting block 62 in the limiting groove 61.

[0042] As the limiting block 62 slides out from the inner wall of the limiting groove 61, the moving block 3 is released from its fixed position and can slide on the outside of the support 2. This drives the upper counterweight box 4 to move to the appropriate position. Rotating the threaded rod 65 causes the limiting block 62 to re-insert into the inner wall of the limiting groove 61. After adjustment, the connector 66 is released. Under the action of the compression spring 67, the connector 66 re-inserts into the inner wall of the moving block 3 to limit the threaded rod 65, thus fixing the positions of the moving block 3 and the counterweight box 4.

[0043] When installing or removing the counterweight 7, pull the limiting rod 51 in the lower connecting assembly of the cover 5 to make it move to the right against the elastic force of the return spring 52, disengage from the insertion hole 53 on the right side of the moving block 3, and release the limiting of the cover 5. At this time, the cover 5 can be opened conveniently to operate the counterweight 7.

[0044] To prevent the counterweight 7 from sliding inside the counterweight box 4 and affecting the counterweight effect, the lead screw 81 in the stabilizing component inside the rotatable slide bar 8 is rotated. Since the lead screw 81 is threadedly connected to the push plate 82, the rotation of the lead screw 81 will cause the push plate 82 to slide on the outside of the slide bar 8, so that the rubber pad on the right side of the push plate 82 tightly squeezes the counterweight 7, increasing the friction and thus firmly fixing the counterweight 7, ensuring that the loader can maintain good balance and stable working condition according to the actual situation during operation.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
