Description

Technical Field

[0001] The utility model relates to the field of engineering machinery, in particular to a quick-disassembly and quick-change traction mechanism of engineering machinery. Background Art

[0002] Loaders are engineering machinery widely used in earthwork construction. A bucket is provided on the front side of the loader, and the bucket is connected to the loader through a boom and an arm. A boom cylinder for controlling the movement of the arm is installed on the upper part of the boom. In addition, a boom cylinder for controlling the movement of the boom is also installed on the excavator. The boom cylinder is supplied with oil through the boom lifting oil circuit, and the boom lifting and falling are controlled by the boom cylinder; the movement of the bucket is controlled by the rocker arm cylinder, which is supplied with oil through the bucket retracting oil circuit, and the rocker arm rotation is controlled by the rocker arm cylinder, driving the bucket to complete the retracting and digging actions.

[0003] At present, due to the fact that construction machinery is rarely used in traction conditions in China, the traction mechanism is mostly a welded structure, which cannot be repaired once it is damaged, and needs to be improved. Utility Model Content

[0004] The utility model aims to solve the above problems and provide a quick-disassembly and quick-change traction mechanism for engineering machinery which is convenient to replace after being damaged.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a quick-release and quick-change traction mechanism for engineering machinery, which has the following structural characteristics: it includes a frame, a counterweight is installed at the rear of the frame, a rear tail plate is installed at the rear end of the frame, an avoidance hole is opened on the counterweight, the avoidance hole runs through the counterweight, a traction mechanism is arranged in the avoidance hole, and the front part of the traction mechanism passes through the avoidance hole and is fixedly connected to the rear tail plate by bolts.

[0006] The counterweight is installed at the rear of the frame, which can increase the stability of the whole machine, especially when towing or operating, it can effectively prevent the machine from tipping over or tilting. The avoidance hole opened on the counterweight not only provides installation space for the towing mechanism, but also makes the overall structure more compact and improves the utilization of space. Through its unique design and construction, it achieves structural stability, convenient operation and safety of use, providing strong support for the efficient operation of construction machinery.

[0007] The traction mechanism includes a base plate, two ear plates are installed on the base plate, and a traction pin is installed between the two ear plates. The traction mechanism forms a stable frame through the base plate and the two ear plates, so that the traction pin can be firmly installed on it. The design of the ear plate allows the traction pin to slide on it, which facilitates the rapid replacement of the traction mechanism.

[0008] The bolts pass through the bottom plate and are tightened on the rear tail plate. The bolts pass through the bottom plate and are tightened on the rear tail plate. This fixing method is simple and effective, and is easy to disassemble and replace.

[0009] The lug plates are spaced apart from each other, and the traction pin is slidably mounted on the two lug plates. The traction pin is inserted with a latch for positioning the traction pin. The use of the latch positions the traction pin, preventing the traction pin from accidentally moving or falling off during operation, thereby enhancing safety.

[0010] The bolt is connected with an anti-lost rope, and the other end of the anti-lost rope is fixed on the ear plate. The anti-lost rope connects the bolt and the ear plate together to prevent the bolt from being lost, and at the same time will not affect the normal use of the bolt.

[0011] A top block is installed on the front side of the bottom plate, and its front end abuts against the rear tail plate. The top block is installed on the front side of the bottom plate, and its front end abuts against the rear tail plate, which increases the connection stability between the traction mechanism and the frame and reduces the possibility of shaking and vibration.

[0012] There are multiple top blocks, and the multiple top blocks extend forward. The design of multiple top blocks extending forward further enhances the stability of the connection, making the traction mechanism more stable and reliable when working.

[0013] The avoidance hole is provided with a retaining edge, which extends toward the center of the avoidance hole, and the rear tail plate extends into the avoidance hole, and the rear tail plate rests on the retaining edge. The retaining edge design in the avoidance hole enables the rear tail plate to rest stably on it, which not only enhances the stability of the structure, but also prevents the traction mechanism from shaking during operation. The rear tail plate extends into the avoidance hole and is tightly combined with the retaining edge. Such a design not only ensures the compactness of the structure, but also enhances the firmness of the connection.

[0014] In summary, the beneficial effects of the utility model are: the counterweight is connected to the frame by bolts; the traction plate is connected to the rear tail plate of the frame by bolts, and can be replaced once it is damaged; there is a certain gap between the traction plate and the frame to ensure that the force during traction is completely borne by the tail plate of the frame; the protrusions designed on the counterweight are separated to ensure sealing; the traction pin is provided with an anti-lost rope to ensure that the pin shaft will not be lost after being removed.

Through its unique design and construction, the stability of the structure, the convenience of operation and the safety of use are achieved, providing strong support for the efficient operation of engineering machinery.

[0028] Refer to the attached Figure 6 The traction mechanism includes a base plate 5, on which two ear plates 1 are mounted, and a traction pin 2 is mounted between the two ear plates 1. The traction mechanism forms a stable frame through the base plate 5 and the two ear plates 1, so that the traction pin 2 can be stably mounted thereon. The design of the ear plate 1 allows the traction pin 2 to slide thereon, which facilitates the rapid replacement of the traction mechanism.

[0029] Refer to the attached Figure 2 , the bolt 3 passes through the bottom plate 5 and is tightened on the rear tail plate 9.
