Description

Technical Field

[0001] The utility model relates to the technical field of garbage grab buckets, in particular to a hydraulic grab bucket oil tank. Background Art

[0002] As the waste-to-energy industry develops, equipment optimization efforts are underway across various processes. 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] The garbage hydraulic grab consists of a fuel tank, a cylinder, a hydraulic system, and bucket flaps. The hydraulic system primarily drives the cylinder, which in turn drives the bucket flaps to open and close, enabling the grabbing and delivery of garbage. Grabbing and delivering garbage to the incinerator is crucial throughout the waste-to-energy process. Frequent malfunctions in the grab will directly impact the efficiency and production capacity of waste-to-energy. Based on numerous repairs to garbage cranes, it was concluded that the mounting holes for the pins in conventional hydraulic grab tanks are severely worn. Due to the harsh operating environment of the grab, some tank outer walls are deformed by impact, and some cylinders are severely corroded or damaged by collisions. These situations typically require the grab to be returned to the factory for an overhaul, significantly increasing repair costs. Utility Model Content

DETAILED DESCRIPTION

[0019] 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.

[0020] like Figure 1 As shown, a hydraulic grab bucket oil tank includes a tank body 2 for providing power hydraulic oil to the oil cylinder 1, a pin shaft ear plate 7 provided on the tank body 2, a pin shaft ear plate cover plate 6 provided on the tank body 2 and used to protect the tank body 2, and a bucket pin shaft mounting seat assembly 4 provided between adjacent pin shaft ear plates 7. The hydraulic grab bucket tank body 2 is the main part of the hydraulic oil tank, used to store hydraulic oil and provide power hydraulic oil to the oil cylinder 1. The hydraulic oil generates a certain pressure under the action of the hydraulic pump and is transmitted to the hydraulic cylinder through the hydraulic pipeline to drive the piston movement of the oil cylinder 1. The oil cylinder 1 ear plate is mainly used to protect the oil cylinder 1 ear plate from erosion and damage from the external environment. At the same time, it can also effectively increase the strength of the oil tank and increase the heat dissipation area of the oil tank. The oil cylinder shield 3 can effectively prevent the oil cylinder 1 from physical damage such as external impact and scratching. At the same time, the oil cylinder shield 3 can also provide a certain degree of heat insulation and dustproofing, reducing the impact of temperature changes and dust contamination on the oil cylinder 1. The oil cylinder guard 3 is bolted to the oil tank housing 2, facilitating disassembly, assembly, maintenance, and replacement. The bucket pin mounting assembly 4, located between adjacent oil tank housings 2, is primarily used to connect and secure the bucket pin 43, a key component for connecting the hydraulic grab bucket's lobes. This assembly improves the hydraulic grab's reliability and stability, ensuring accurate opening and closing of the bucket, and enhancing its efficiency and accuracy.

[0021] A cylinder baffle 5 is installed on the outside of the oil cylinder 1. A cylinder guard 3 is installed on the outside of the cylinder baffle 5 and is bolted to the oil tank body 2. The cylinder baffle 5 is used to prevent the oil cylinder 1 from moving or colliding during operation. The cylinder baffle 5 is usually connected to the oil tank body 2 by bolts or welding.

[0022] like Figure 2As shown, the bucket pin mounting assembly 4 includes a tank pin mounting seat 40 provided on the tank body 2, a pin pressing seat 42 located at the upper end of the tank pin mounting seat 40 and connected to the tank pin mounting seat 40 via a locking member 41, and a pin 43 assembled between the tank pin mounting seat 40 and the pin pressing seat 42. The pin pressing seat 42 presses and fixes the pin 43 to the tank pin mounting seat 40. The locking member 41 adopts a hexagon socket screw. After the pin pressing seat 42, the pin 43 and the tank pin mounting seat 40 are pressed, the pin 43 cannot move or rotate, thereby achieving reliable positioning. When the pin 43 needs to be replaced, it is only necessary to remove the hexagon socket screw and the pin pressing seat 42, and then lift the bucket to remove the pin 43 and replace it. Maintenance is simple, which can greatly reduce the maintenance frequency and increase the service life. The end face of the pin 43 is provided with a bucket gasket 44.

[0023] like Figure 3 As shown, the fuel tank pin mounting base 40 is provided with an arc surface 400 of equal diameter to the pin 43. The end surface of the fuel tank pin mounting base 40 is provided with a mounting hole 401 for mounting a locking member 41. The pin 43 abuts against the arc surface 400 of the fuel tank pin mounting base 40. The arc surface 400 on the fuel tank pin mounting base 40 is equal in diameter to the pin 43, ensuring that the pin 43 can accurately abut against the arc surface 400 during installation. This precise fit helps reduce the shaking of the pin 43 when rotating or under stress, improving the stability and reliability of the connection. The design of the arc surface 400 makes it easier for the pin 43 to slide into place during installation, reducing the difficulty of installation. At the same time, the arc surface 400 also provides a clear positioning point, helping to ensure the correct position of the pin 43 during installation. The mounting hole 401 on the end surface of the fuel tank pin mounting base 40 provides an installation location for the locking member 41 (such as a hexagon socket head screw). The pin shaft pressing seat 42 is fixed to the oil tank pin shaft mounting seat 40 through the locking piece 41, thereby achieving reliable fixation of the pin shaft 43.

[0024] like Figure 4As shown, the pin shaft pressing seat 42 is provided with an arc surface 400 with the same diameter as the pin shaft 43. The arc surface 400 on the pin shaft pressing seat 42 corresponds to the arc surface 400 on the oil tank pin shaft mounting seat 40, and the end of the pin shaft pressing seat 42 is also provided with a mounting hole 401 for installing the locking member 41. The pin shaft 43 abuts and cooperates with the arc surface 400 of the pin shaft pressing seat 42, and the locking member 41 is connected between the mounting hole 401 of the oil tank pin shaft mounting seat 40 and the mounting hole 401 of the pin shaft pressing seat 42. The arc surface 400 on the pin shaft pressing seat 42 and the oil tank pin shaft mounting seat 40 are both of equal diameter to the pin shaft 43. This design ensures that the pin shaft 43 can be accurately and firmly matched between the two arc surfaces 400. The design of the double arc surface 400 increases the contact area between the pin shaft 43 and the seat body, eliminates the gap between the pin shaft 43 and the seat body, and helps to prevent the pin shaft 43 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 when working. Thereby improving the stability and load-bearing capacity of the connection. The locking member 41 (such as a hexagon socket screw) achieves reliable fixation of the pin shaft 43 by connecting the mounting hole 401 on the oil tank pin shaft mounting seat 40 and the pin shaft pressing seat 42. The tightening effect of the locking member 41 ensures that the pin shaft 43 will not loosen or fall off when subjected to force, thereby ensuring the normal operation of the garbage grab.

[0025] 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.
