Description

Technical Field

[0001] The utility model relates to the technical field of mobile devices, in particular to the field of crawler mobile devices, and specifically refers to a split crawler frame. Background Art

[0002] As a mobile device, the crawler mobile device has stronger off-road mobility than the wheeled mobile device, and is particularly suitable for soft, muddy or rugged ground. Therefore, it is widely used in mechanical equipment that needs to work in various complex terrains, such as small agricultural machinery, tractors, etc.

[0003] At present, the common crawler mobile device is usually mainly composed of a power mechanism, a transmission mechanism and a traveling mechanism. The traveling mechanism of the crawler mobile device usually includes a connecting frame, two integrated crawler frames fixed on the left and right sides of the connecting frame, and a driving wheel, an inducer wheel, a load-bearing wheel, a towing wheel, a crawler, and a tensioning device installed on the integrated crawler frame. During the production or maintenance of the crawler mobile device, it is necessary to adjust the distance between the driving wheel shaft and the inducer wheel shaft to facilitate the installation and removal of the crawler; in addition, in order to prevent the crawler from falling off or excessive wear and breakage due to improper tightness of the crawler, it is often necessary to adjust the distance between the driving wheel shaft and the inducer wheel shaft during daily use and maintenance.

[0004] In the existing crawler moving device, in order to be able to adjust the distance between the driving wheel shaft and the idler wheel shaft, long slots are usually opened at the positions where the idlers are installed on the left and right sides of the integrated crawler frame and a tensioning device is installed, so that the idler wheel shaft passes through the long slots on the left and right sides of the integrated crawler frame and is connected to the screws on the tensioning devices on both sides. By adjusting the extended lengths of the screws in the tensioning devices on the left and right sides of the integrated crawler frame respectively, the idler wheel shaft slides along the long slots on the integrated crawler frame, thereby achieving the purpose of adjusting the distance between the driving wheel shaft and the idler wheel shaft.

[0005] However, when the above adjustment method is adopted to adjust the distance between the driving wheel shaft and the idler wheel shaft, since the extension lengths of the screw rods in the tensioning devices on the left and right sides of the integrated crawler frame are adjusted separately, it is difficult to ensure that the extension lengths of the screw rods on both sides remain consistent after adjustment, which makes it difficult for the adjusted idler wheel shaft and the driving wheel shaft to reach a state of parallelism. If the idler wheel shaft and the driving wheel shaft cannot maintain a parallel state, it is very easy to cause abnormal wear, breakage, and falling off of the crawler track, affecting the service life of the crawler track and increasing the maintenance cost of the crawler moving device. At the same time, it will also affect the stability and controllability of the crawler moving device during operation and increase the energy consumption of the crawler moving device. Therefore, in order to make the idler wheel shaft and the driving wheel shaft reach a state of parallelism, the extension lengths of the screw rods in the tensioning devices on the left and right sides of the integrated crawler frame have to be repeatedly adjusted, resulting in low labor efficiency and poor effect of the adjustment work.

[0006] In addition, since there are various gaps between the idler shaft and the long slot of the integrated track frame, between the tensioner and the idler shaft, and inside the tensioner, after the adjustment is completed, the adjustment result will often change due to factors such as vibration during the operation of the crawler moving device, affecting the final adjustment effect. Utility Model Content

[0007] The utility model aims at the deficiencies of the prior art and provides a split crawler frame with high adjustment efficiency and good adjustment effect.

[0008] The utility model is implemented through the following technical scheme, providing a split crawler frame, including a first bracket and a second bracket, the first bracket is connected to the second bracket through a first connecting component, the first bracket is connected to the second connecting component, the second bracket is connected to the third connecting component, and the third connecting component is plugged into the second connecting component.

[0009] Compared with the prior art, the beneficial effects of the utility model are that the first bracket and the second bracket can both be used to install the driving wheel or the inducer wheel of the crawler moving device. Since the third connecting component is plugged into the second connecting component, the spacing between the second bracket and the first bracket can be adjusted by adjusting the plugging depth between the third connecting component and the second connecting component, thereby achieving the purpose of adjusting the spacing between the driving wheel shaft and the inducer shaft. Moreover, since the relative position between the inducer shaft and the first bracket or the second bracket is fixed when adjusting the spacing between the driving wheel shaft and the inducer shaft, the problem of the inducer shaft and the driving wheel shaft being not parallel due to adjusting both sides of the inducer shaft separately is avoided. At the same time, since only the third connecting component needs to be adjusted, the work efficiency during adjustment is greatly improved compared with the existing adjustment method.

[0010] Preferably, the second connecting component is a sleeve structure, and the inner cavity wall of the second connecting component is in contact with the third connecting component.

[0011] Preferably, the second connecting component is connected to the first positioning component, and the first positioning component is in contact with the third connecting component.

[0012] The beneficial effect of adopting the above-mentioned preferred technical scheme is that: through the first positioning component, the depth of the third connecting component in the second connecting component can be limited, thereby facilitating accurate adjustment of the spacing between the first bracket and the second bracket. Since the second connecting component is a sleeve structure, and the inner cavity wall of the second connecting component is in contact with the third connecting component, the third connecting component can be moved in the inner cavity of the sleeve of the second connecting component along the axial direction of the second connecting component while preventing the third connecting component from rotating or radially translating in the second connecting component. Therefore, when adjusting the spacing between the first bracket and the second bracket, the parallelism between the driving wheel shaft and the inducer wheel shaft is ensured, and at the same time, after the driving wheel shaft and the inducer wheel shaft are adjusted, the spacing or parallelism between the driving wheel shaft and the inducer wheel shaft is prevented from changing due to vibration during operation and other reasons.

[0013] Preferably, the first bracket and the second bracket are both provided with a fourth connecting component, the first bracket and the second bracket are respectively provided on both sides of the split crawler frame, and the first brackets and the second brackets on both sides of the split crawler frame are respectively connected to each other through a fifth connecting component, and the fifth connecting component is plugged into the fourth connecting component.

[0014] Preferably, the fourth connecting component is a sleeve structure, and the inner cavity wall of the fourth connecting component is in contact with the fifth connecting component.

[0015] Preferably, the fourth connecting component is connected to the fifth connecting component via a second positioning component.

[0016] The beneficial effect of adopting the above-mentioned preferred technical scheme is that: since the fourth connecting component is a sleeve structure, the inner cavity wall of the fourth connecting component fits with the fifth connecting component, and the fourth connecting component is connected to the fifth connecting component through the second positioning component. Therefore, after the fifth connecting component is connected to the first bracket and the second bracket on both sides of the split track frame, the fifth connecting component can be prevented from axial movement, radial movement or rotation in the fourth connecting component, so that the fifth connecting component is firmly fixed in the fourth connecting component, and then the first bracket and the second bracket on both sides of the split track frame are connected into a firm whole through the fifth connecting component.

[0017] Preferably, the first bracket is provided with an adjustment opening.

[0018] The beneficial effect of adopting the above-mentioned preferred technical solution is that: through the adjustment port on the first bracket, the depth of the first positioning component in the inner cavity of the second connecting component can be easily adjusted, which is beneficial to improving the work efficiency of adjusting the distance between the inducer wheel shaft and the driving wheel shaft.
