Description

Technical Field

[0001] The utility model belongs to the technical field of construction machinery assembly workshops and relates to a crawler flexible assembly paving system. Background Technique

[0002] The crawler is an important part of the walking mechanism of an excavator. It enables the excavator to move flexibly in complex terrains and narrow spaces, enhancing the passability of the excavator. The proper assembly of the crawler is crucial for the normal operation of the excavator, which can improve the stability and safety of the equipment.

[0003] The assembly of the crawler is usually completed by an operator with the aid of a crane in one go, including the spreading of the crawler roll, the co-assembly with the frame, and the wrapping. With the progress of industry technology, there have also emerged various devices for assisting crawler assembly in the industry, such as using wire ropes to tow and wrap the crawler, or using semi-automatic trolleys to push the crawler for spreading and using a crane for hoisting and wrapping. The above-mentioned various methods all have some deficiencies, resulting in high assembly noise, low efficiency, high manual labor intensity, and low assembly accuracy, specifically as follows: When spreading the crawler by towing with a wire rope, the operator needs to tow the wire rope, and there is a safety risk of wire rope breakage, and the noise during the process of crawler unfolding and rolling is relatively large; When pushing the crawler for spreading by a semi-automatic trolley, after setting a push plate mechanism for positioning the crawler at the front end of the trolley, the distance between the trolley and the crawler is relatively large, and the length of the trolley push rod arm is up to 1800 mm, resulting in poor rigidity of the trolley push rod ratio, low efficiency and poor accuracy of crawler spreading; After the crawler and the frame are co-assembled, when wrapping the crawler by a crane or a wire rope, it is difficult to correct the crawler, with low wrapping efficiency, high manual labor intensity, and certain safety risks.

[0023] In this embodiment, the vehicle frame transfer mechanism is an RGV or an AGV.

[0024] In this embodiment, the crawler spreading platform 1 is a workbench surface for assembling the crawler after spreading; the crawler centering and positioning platform 2 and the crawler unwinding, rolling and wrapping trolley 4 are of an integrated structure. During the crawler centering process, the trolley can move synchronously with the centering mechanism, greatly reducing the working arm length of the trolley swing rod; the scissor lift 6 is used for detaching the vehicle frame transfer mechanism from the vehicle frame 5 after the vehicle frame 5 and the crawler are assembled; the sunken crawler follower device 7 is used for the crawler to follow the unwinding and rolling during the crawler spreading process, reducing the noise during the spreading process.

[0025] In this embodiment, the crawler centering and positioning platform 2 can automatically push the crawler to the assembling station according to the model of the crawler and synchronously correct the straightness of the crawler.

[0026] The working process of the present utility model is as follows:

[0027] S1, the assembler uses the crane to hoist the crawler into the sunken crawler follower 7, and at the same time fixes the crawler traction swing rod 402 of the crawler unwinding and wrapping trolley 4 to the crawler end, and controls the trolley to move horizontally through the control system to pull the crawler to spread; during the crawler spreading process, the crawler follower chain 702, the rear follower roller 701, and the front follower roller 703 of the sunken crawler follower 7 all rotate synchronously with the crawler, reducing the friction during the crawler rotation process and reducing the noise during the crawler spreading process;

[0028] S2, after the crawler tracks are fully extended, the control system automatically controls the crawler track centering positioning platform 2 to move inward according to the crawler track model, and automatically pushes the crawler tracks to the designated assembly position simultaneously;

[0029] S3, the RGV or AGV carries the frame 5 to the crawler assembly station of the scissor lift 6, and the scissor lift 6 automatically descends to realize the automatic assembly of the supporting wheels, guide wheels, and driving wheels with the crawler. At the same time, the scissor lift 6 is lowered to the lowest position, and the RGV or AGV is separated from the frame 5 and moves backward out of the assembly station;

[0030] S4, after the frame 5 and the crawler track are assembled, the control system automatically controls the crawler traction swing rod 402 of the crawler track of the crawler unrolling and wrapping trolley 4 to swing upward, lift the crawler track to the assembly height, and the crawler unrolling and wrapping trolley 4 moves in the opposite direction, and the traction crawler track is assembled with the supporting wheels, guide wheels, and the upper part of the driving wheel;

[0031] S5, after the crawler track is assembled, the crawler track centering positioning platform 2 moves outward to separate the traction swing arm from the crawler track, and the crawler track pin assembly is completed manually;

[0032] S6, after the crawler pin assembly is completed, the RGV or AGV moves to the assembly station, lifts the frame 5, and then transfers the frame 5 to the next assembly station.

[0033] In this embodiment, the crawler flexible assembly and paving system can call the control program according to different machine models to realize automatic paving, positioning assembly, automatic wrapping, etc. of the crawler, which greatly improves the automation level of crawler assembly and reduces the intensity of manual labor.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
