[0001] The utility model relates to the technical field of mechanical linkages, and particularly relates to a construction machinery linkage with adjustable length. Background Technique

[0002] The linkage mechanism, also known as a lower pair mechanism, is a type of component in machinery. It refers to a mechanism composed of several (more than two) components with definite relative motions connected by lower pairs (rotary pairs or sliding pairs). The planar linkage mechanism is a common transmission mechanism, and its most basic and widely used form is the planar four-bar mechanism composed of four components. Since most components in the mechanism are rod-shaped, the rod-shaped components are often called rods.

[0003] For example, the utility model with the application number CN202321134433.7 provides a construction machinery linkage, which relates to the technical field of mechanical linkages. By setting an oil storage chamber, a plug, an oil delivery pipe, a conveying pipe, and ball bearings, the smoothness of rotation between the linkages is improved, and it is not necessary for people to manually replenish frequently, avoiding wear at the positions of the linkages. When in use, due to damage at the connection, the connection may fall off, leading to accidents, and avoiding damage to the positions of the linkages due to large frictional force, so that people do not need to replenish lubricating oil at each connection of the linkages, thus improving work efficiency; however, the length of the existing mechanical linkages is relatively fixed, and it is inconvenient to adjust the length of the linkages according to the required length during use, resulting in inconvenience in use.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a construction machinery linkage with adjustable length is provided. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A construction machinery linkage with adjustable length, including a rod body and an adjustment component. Adjustment holes are provided on the side surface of the rod body, and the adjustment component for adjusting the length of the rod body is arranged inside the adjustment holes, and the number of the adjustment components is set to two groups. The adjustment component includes a telescopic rod, a connecting plate, a hydraulic rod, and a mounting plate. A connecting plate is installed on the side surface of the telescopic rod, a hydraulic rod is installed on the side of the connecting plate, and the fixed end of the hydraulic rod is connected to the mounting plate.

[0007] Furthermore, the telescopic rod and the connecting plate are fixedly connected, and the connecting plate and the adjustment hole are slidably connected.

[0008] Furthermore, a side mounting frame is installed on the rear side of the rod body, and the shape of the side mounting frame is U-shaped.

Detailed implementation manners

[0021] The following further describes in detail the implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 shown, an adjustable-length construction machinery connecting rod includes a rod body 1 and an adjustment component 3. An adjustment hole 2 is provided on the side surface of the rod body 1. The adjustment hole 2 is used for the installation of the adjustment component 3 and provides an adjustment space. The adjustment component 3 for adjusting the length of the rod body 1 is arranged inside the adjustment hole 2, and the number of the adjustment components 3 is set to two groups. The adjustment component 3 includes a telescopic rod 301, a connecting plate 302, a hydraulic rod 303 and a mounting plate 304. A connecting plate 302 is installed on the side surface of the telescopic rod 301. The telescopic rod 301 moves inside the end of the rod body 1 to adjust the overall length of the connecting rod, and the adjustment is simple and fast. A hydraulic rod 303 is installed on the side of the connecting plate 302. The hydraulic rod 303 provides adjustment power for the telescopic rod 301 to move inside the rod body 1 by controlling the telescopic movement. The fixed end of the hydraulic rod 303 is connected with a mounting plate 304. The telescopic rod 301 and the connecting plate 302 are fixedly connected. The connecting plate 302 is limited and slides in the adjustment hole 2 to increase the movement stability of the telescopic rod 301, and the connecting plate 302 and the adjustment hole 2 are in sliding connection.

[0023] As Figure 2 shown, a side mounting frame 4 is installed on the rear side of the rod body 1, and the shape of the side mounting frame 4 is a U-shaped. A connecting plate 5 is rotatably installed inside the side mounting frame 4. The connecting plate 5 rotates inside the side mounting frame 4 to adjust the angle as the telescopic rod 301 expands and contracts at the end of the rod body 1. The end of the connecting plate 5 is connected with a rotating sleeve 6. A central rod 7 is arranged inside the rotating sleeve 6. The rotating sleeve 6 rotates up and down at the upper and lower ends of the central rod 7 as the connecting plate 5 rotates to adapt to the length adjustment of the rod body 1 and the telescopic rod 301.

[0024] As Figure 3As shown, an auxiliary component 8 for length adjustment is provided on the side of the central rod 7. The auxiliary component 8 includes an auxiliary block 801 and a movable hole 802. The movable hole 802 is provided on the surface of the auxiliary block 801. The auxiliary component 8 also includes an auxiliary rod 803 and an anti-detachment plate 804. The auxiliary rod 803 is provided inside the movable hole 802. The auxiliary rod 803 moves with the telescopic rod 301 and slides in the movable hole 802 on the auxiliary block 801 to adjust its position, thereby increasing the stability of the telescopic rod 301 in the rod body 1. The anti-detachment plate 804 is installed at the end of the auxiliary rod 803. Two sets of auxiliary rods 803 and anti-detachment plates 804 are symmetrically arranged about the central axis of the auxiliary block 801. The auxiliary rods 803 and anti-detachment plates 804 are an integrated structure. The anti-detachment plate 804 prevents the auxiliary rod 803 from slipping in the movable hole 802.

[0025] In summary, this adjustable-length engineering machinery linkage is first based on... Figures 1-3 The structure shown is used such that, during operation, the mounting rings at the ends of the rod body 1 and the telescopic rod 301 are assembled with the engineering machinery. When adjusting the length of the connecting rod, the telescopic rod 301 is controlled to retract, causing the connecting plate 302 to move inside the adjustment hole 2. This drives the telescopic rod 301 to move inside the end of the rod body 1, thereby adjusting the overall length of the connecting rod. The adjustment is simple and quick. When the connecting plate 302 slides in the adjustment hole 2, it can also increase the stability of the telescopic rod 301. As the telescopic rod 301 moves, the connecting plate 5 at the end of the rod body 1 rotates to adjust the angle inside the side mounting bracket 4. The rotating sleeve 6 rotates at the upper and lower ends of the central rod 7 as the connecting plate 5 rotates, adapting to the length adjustment of the rod body 1 and the telescopic rod 301. At the same time, the auxiliary rod 803 moves with the telescopic rod 301 and slides in the movable hole 802 on the auxiliary block 801 to adjust its position, further increasing the stability of the telescopic rod 301 in the rod body 1. During adjustment, the anti-slip plate 804 prevents the auxiliary rod 803 from slipping out of the movable hole 802, increasing stability.
