Description

Technical Field

[0001] The utility model relates to the technical field of garbage grab buckets, in particular to a bucket pin shaft installation structure of a garbage grab bucket. Background Art

[0002] As the waste-to-energy industry develops, optimization efforts are underway across various process equipment. However, there is still room for improvement in the maintenance and repair of waste cranes. Due to their harsh operating environments and large size, waste cranes are difficult to maintain and repair. Current improvements should focus on reducing maintenance effort, decreasing repair frequency, and increasing service life.

[0003] A garbage grab consists of a fuel tank, a cylinder, a hydraulic system, and bucket flaps. The grab's hydraulic system primarily drives the cylinder, which in turn drives the bucket flaps to open and close, enabling the grab and release of garbage. Grabbing and releasing garbage into the incinerator is crucial to the entire waste-to-energy process. Frequent failures of the grab will directly impact the efficiency and capacity of the waste-to-energy system. Numerous repairs to garbage cranes have revealed that failures are typically caused by severe wear on the connecting pins and sleeves between the bucket flaps and the fuel tank. Testing has shown that increasing the lubrication frequency and oil storage capacity of the sleeves and pins can significantly reduce wear on the pins and sleeves. However, the oil storage capacity of conventional pins and sleeves cannot meet actual usage requirements, and increasing the lubrication frequency will undoubtedly increase maintenance costs. Conventional pins often deform due to structural problems, corrosion, or severe wear, making them difficult to disassemble and assemble. Due to the limited space for the garbage pin shaft, in order to reduce the difficulty of pin installation, the gap between the oil tank pin shaft hole and the pin shaft is designed to be too large. As a result, after the pin shaft is worn, the oil tank pin shaft hole is easily worn due to the movement of the pin shaft. After the oil tank pin shaft hole is worn, it can only be repaired by secondary processing, which will undoubtedly increase the difficulty of maintenance and thus increase the maintenance cost.

DETAILED DESCRIPTION

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] like Figures 1 to 2 As shown, a bucket pin installation structure of a garbage grab bucket includes a bucket body 1, a bucket spacer 2, a shaft sleeve 3, an oil tank pin seat 5, a pin 7 and a pin pressing seat 8;

[0020] The bucket valve spacer 2 is installed in the inner hole of the bucket valve body 1, the shaft sleeve 3 is installed in the pin shaft hole of the bucket valve body 1, the bucket valve spacer 2 is installed between the two shaft sleeves 3, and the oil seal 6 is installed at both ends of the two shaft sleeves 3. The bucket valve body 1 is provided with an oil filling port 11, and the position of the oil filling port 11 is opposite to the position of the bucket valve spacer 2. The oil tank pin shaft seat 5 is fixedly set on the oil tank 10 of the garbage grab bucket, and the pin shaft pressing seat 8 is connected to the oil tank pin shaft seat 5 through the locking piece 9, and the pin shaft pressing seat 8 presses the pin shaft 7 and fixes it on the oil tank pin shaft seat 5.

[0021] The locking member 9 adopts an internal hexagon screw. After the pin shaft pressing seat 8, the pin shaft 7 and the oil tank pin shaft seat 5 are pressed, the pin shaft 7 cannot move or rotate, thus achieving reliable positioning. When the pin shaft 7 or the sleeve 3 needs to be replaced, it is only necessary to remove the internal hexagon screw and the pin shaft pressing seat 8, and then lift the bucket body 1 to remove the pin shaft 7 and the sleeve 3 and replace them. The maintenance is simple, which can greatly reduce the maintenance frequency and increase the service life. The sleeve 3 is installed in the inner hole of the bucket body 1 to isolate and protect the pin shaft 7. By reducing the direct contact between the pin shaft 7 and the bucket body 1, the service life of the pin shaft 7 is extended. The bucket spacer 2 is installed in the inner hole of the bucket body 1. The bucket spacer 2 is installed between the two sleeves 3. The oil filling port 11 is located opposite the bucket spacer 2 to facilitate lubrication and reduce friction. An oil seal 6 is provided at each end of the sleeve 3. The oil seal 6 can seal to prevent the internal grease from flowing out, thereby increasing the oil storage capacity of the sleeve 3. It can also prevent external corrosive liquids from entering the pin 7 and the interior of the sleeve 3, preventing corrosion at the friction point of the sleeve 3. It is connected to the pin 7, effectively increasing the lubrication effect, reducing the friction between the pin 7 and the sleeve 3, and improving the rotation flexibility and service life of the pin 7. The oil tank pin seat 5 serves as the installation base for the pin 7, providing stable support to ensure that the pin 7 can be reliably fixed in place. The pin pressing seat 8 is connected to the oil tank pin seat 5 by the hexagon socket screw of the locking member 9, pressing and fixing the pin 7 to the oil tank pin seat 5 to ensure the stability of the pin 7. A bucket gasket 4 is provided between the end face of the bucket body and the oil tank pin seat 5.

[0022] like Figure 3As shown, the fuel tank pin holder 5 features a circular surface 12 of equal diameter to the pin 7. The end surface of the pin holder 5 is provided with a mounting hole 13 for mounting a locking member 9. The pin 7 abuts against the circular surface 12 of the pin holder 5. The circular surface 12 of the pin holder 5 is equal in diameter to the pin 7, ensuring that the pin 7 precisely abuts against the circular surface 12 during installation. This precise fit helps prevent the pin 7 from rotating or shaking when subjected to force, improving the stability and reliability of the connection. The design of the circular surface 12 makes it easier for the pin 7 to slide into place during installation, reducing installation difficulty. The circular surface 12 also provides a clear positioning point, helping to ensure the pin 7 is correctly positioned during installation. The mounting hole 13 on the end surface of the pin holder 5 provides a mounting location for a locking member 9, such as a hexagon socket head cap screw. The locking member 9 secures the pin pressure seat 8 to the pin holder 5, reliably securing the pin 7.

[0023] like Figure 4 As shown, the pin pressing seat 8 is provided with an arc surface 12 of the same diameter as the pin 7. The arc surface 12 on the pin pressing seat 8 corresponds to the arc surface 12 on the fuel tank pin seat 5. The end of the pin pressing seat 8 is also provided with a mounting hole 13 for mounting the locking member 9. The pin 7 abuts and cooperates with the arc surface 12 of the pin pressing seat 8. The locking member 9 is connected between the mounting hole 13 of the fuel tank pin seat 5 and the mounting hole 13 of the pin pressing seat 8. The locking member 9 is a hexagon socket screw, and the mounting hole 13 is a threaded hole. The arc surface 12 on the pin shaft pressing seat 8 and the oil tank pin shaft seat 5 are both of equal diameter to the pin shaft 7. This design ensures that the pin shaft 7 can be accurately and firmly matched between the two arc surfaces 12. The design of the double arc surface 12 increases the contact area between the pin shaft 7 and the seat body, reduces the gap between the pin shaft 7 and the seat body, and helps to prevent the pin shaft 7 from shaking and rotating when subjected to force, thereby improving the stability of the connection and ensuring the stability and reliability of the garbage grab during operation. This improves the stability and load-bearing capacity of the connection. The locking member 9, such as a hexagon socket screw, connects the mounting hole 13 on the oil tank pin shaft seat 5 and the pin shaft pressing seat 8 to achieve reliable fixation of the pin shaft 7. The tightening effect of the locking member 9 ensures that the pin shaft 7 will not loosen or fall off when subjected to force, thereby ensuring the normal operation of the garbage grab.

[0024] like Figure 5 As shown, steps 20 are provided on the outer circumference of both ends of the hopper spacer 2, and a through hole 21 for grease passage is provided on the hopper spacer 2 between the two sets of steps 20. The provision of the steps 20 helps provide a positioning point during the installation of the hopper spacer 2, ensuring that the spacer can be properly installed in the inner hole of the hopper body 1. At the same time, the steps 20 also play a supporting role, increasing the stability of the hopper spacer 2 and preventing it from displacement or deformation when subjected to force. The inner hole of the hopper spacer 2 is larger than the outer circumference of the pin 7, and there is no contact between the two, so there is no friction between the hopper spacer 2 and the pin 7 when the hopper body 1 rotates.

[0025] The design of the through hole 21 allows lubricants such as butter to pass through, thereby lubricating the bucket spacer 2, the pin 7 and the sleeve 3. The addition of lubricants can reduce friction and wear, extend the service life of components, and improve the operating efficiency of the entire mechanism.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
