Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic slag buckets, in particular to a hydraulic slag bucket oil tank. 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 structure of the waste bucket. The bucket operates in harsh environments and is large, making maintenance and repair difficult. The current direction of improvement should be to reduce maintenance difficulty and repair frequency.

[0003] The slag bucket consists of a fuel tank, a fuel cylinder, a lifting beam, a hydraulic system, and a bucket body. The slag bucket is primarily driven by the hydraulic system to drive the fuel cylinder, which in turn drives the bucket body to open and close, enabling the grabbing and dropping of the slag. In the entire waste-to-energy process, the process of grabbing the slag after incineration and dropping it onto the dump truck is equally important. Conventional slag buckets have severe deformation in the slag bucket body's pin mounting holes, and localized pin mounting holes are severely worn. Due to the harsh operating environment of garbage grabs, some of the outer walls of the fuel tanks are deformed due to impacts. This deformation of the slag bucket body's pin mounting holes requires secondary processing before it can be used again. Typically, these situations require the slag bucket to be returned to the factory for overhaul.

[0004] In the existing hydraulic hopper oil tank, the oil tank pin fixing plate and the oil tank pin fixing sleeve are welded and fixed to the oil tank. The conventional hopper pin installation is to fix the pin to the bucket body connecting hinge plate, and the pin is fixed to the oil tank pin fixing sleeve by bolts. In this installation method, the pin has only one support point relative to the hopper oil tank, the oil tank pin fixing sleeve, and there is relative movement between the pin fixing sleeve and the pin, which usually causes severe extrusion, wear and deformation of the fixing sleeve. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a hydraulic slag hopper oil tank.

[0006] The utility model solves the above technical problems with the following technical solutions: a hydraulic slag hopper oil tank, comprising an oil tank body, oil tank rib frames respectively arranged at both ends of the oil tank body, and a bucket body pin shaft fixing assembly arranged on the oil tank rib frames away from the end surface of the oil tank body;

[0007] The bucket body pin fixing assembly includes a bucket body pin fixing plate, a mounting hole opened in the bucket body pin fixing plate, and a pin installed in the mounting hole. The pin is fixed to the bucket body pin fixing plate through a locking piece, and the bucket body of the slag bucket is connected to the pin through a shaft sleeve.

[0008] Furthermore, the fuel tank rib frame includes four outer ribs in an enclosing structure, an outer rib cover plate arranged above the outer ribs, and an outer rib bottom plate arranged below the outer ribs, and the bucket body pin shaft fixing assembly is arranged on the end face of the outer ribs.

[0009] Furthermore, a cylinder pin fixing sleeve is provided on the outer rib plate.

[0010] Furthermore, the bucket body pin shaft fixing plate includes two fixing steel plates and a supporting steel plate clamped between the two fixing steel plates, and the mounting hole passes through the two fixing steel plates.

[0011] Furthermore, the upper end of the fuel tank body is respectively provided with a fuel tank cover mounting flange, a return oil filter mounting flange and an oil filling port.

[0012] Furthermore, an oil unloading port is provided below the oil tank body.

[0013] The utility model has the following beneficial effects: The hydraulic slag bucket oil tank provided by the utility model has two support points for the pin on the bucket body pin fixing assembly, which is structurally reliable. After the pin is fixed with bolts, the pin does not rub against the oil tank. During the opening and closing of the bucket body, only the shaft sleeve inside the bucket body rubs against the pin, without damaging the bucket body pin fixing plate, thereby preventing damage to the oil tank, greatly extending its service life and avoiding secondary processing during maintenance. In addition, an oil discharge port is provided at the bottom of the oil tank body, which allows the hydraulic oil and oil contamination in the oil tank to be completely discharged through external operation, which is convenient to operate.

DETAILED DESCRIPTION

[0017] 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.

[0018] like Figures 1 to 2As shown, a hydraulic slag hopper oil tank comprises a tank body 1, a tank rib frame 2 disposed at each end of the tank body 1, and a bucket body pin fixing assembly 3 disposed on the end face of the tank rib frame 2 away from the tank body 1. The tank body 1 is the main structure of the hydraulic slag hopper oil tank and is used to store hydraulic oil. The tank rib frame 2 is disposed at each end of the tank body 1 and is used to enhance the strength and rigidity of the tank body 1. It also supports and secures the bucket body pin fixing assembly 3. The bucket body pin fixing assembly 3 is used to connect and secure the bucket body, ensuring that the bucket body can be stably mounted on the hydraulic slag hopper oil tank. It also transmits torque and withstands pressure.

[0019] The bucket body pin fixing assembly 3 includes a bucket body pin fixing plate 30, a mounting hole defined in the bucket body pin fixing plate 30, and a pin 31 that fits within the mounting hole. Pin 31 is secured to the bucket body pin fixing plate 30 via a locking member 32. The bucket body is connected to pin 31 via a bushing 33. The bucket body pin fixing plate 30 is the foundation of the bucket body pin fixing assembly 3, used to mount and secure pin 31. It provides a stable support surface for pin 31, ensuring that it can be accurately positioned in the desired location. The bucket body pin fixing plate 30 has a dual-support structure. The pin 31 has two support points on the bucket body pin fixing assembly 3. After the pin 31 is fixed with bolts, the pin 31 does not rub against the fuel tank. Only the sleeve 33 inside the bucket body rubs against the pin 31, which does not damage the bucket body pin fixing plate 30. This prevents damage to the fuel tank and avoids secondary processing during maintenance. The sleeve 33 is installed at the connection between the pin 31 and the bucket body to reduce friction and wear. The locking member is a bolt.

[0020] The bucket body pin fixing plate 30 consists of two fixed steel plates 301 and a support steel plate 302 sandwiched between the two fixing plates 301. Mounting holes extend through both fixing plates 301. The two fixing plates 301 provide dual support for the pin 31, significantly enhancing the stability of the connection. The support steel plate 302, located between the two fixing plates 301, acts as a reinforcing rib, further enhancing the overall strength of the bucket body pin fixing plate 30. The support steel plate 302 effectively distributes stress, reducing the risk of structural damage caused by concentrated stress.

[0021] The fuel tank rib frame 2 consists of four enclosing outer ribs 20, an outer rib cover 21 positioned above the outer ribs 20, and an outer rib bottom 22 positioned below the outer ribs 20. The bucket body pin fixing assembly 3 is mounted on the end surface of the outer ribs 20, and the outer ribs 20 are equipped with cylinder pin fixing sleeves 23. The outer rib cover 21, positioned above the outer ribs 20, provides a seal and protection, preventing external impurities from entering the fuel tank. The outer rib bottom 22, positioned below the outer ribs 20, further strengthens the bottom support of the fuel tank and improves overall stability.

[0022] The upper end of the oil tank body 1 is provided with an oil tank cover mounting flange 10, a return oil filter mounting flange 11, and an oil filling port 12, and an oil discharge port 13 is provided at the bottom of the oil tank body 1. The oil tank cover mounting flange 10 is used to fix the oil tank cover to ensure the sealing and integrity of the oil tank. It provides a standardized connection interface to facilitate the installation and removal of the oil tank cover, enhance the sealing performance of the oil tank, and prevent oil leakage. The return oil filter mounting flange 11 is used to install the return oil filter to filter the oil returned from the hydraulic system, ensure the cleanliness of the oil, and extend the service life of the hydraulic system. The oil filling port 12 is used to add oil to the oil tank. The oil discharge port 13 is used to discharge the oil in the oil tank and is located at the bottom of the oil tank body 1. When it is necessary to drain the oil or drain the sewage, it is only necessary to remove the cap nut of the bottom sewage outlet, which is convenient to operate.
