Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic pumps, and particularly relates to a hydraulic pump with a pressure conversion function. Background Art

[0002] A hydraulic pump is a power element of a hydraulic system. Driven by an engine or a motor, it can convert low-pressure oil sucked from a hydraulic oil tank into high-pressure oil and send the high-pressure oil to an actuator. At present, when a hydraulic pump is installed and fixed, it is basically fixed by tightening multiple groups of bolts. When disassembling and installing, it is necessary to install and disassemble multiple groups of bolts one by one, which is not convenient to operate. Moreover, during the installation and disassembly of the bolts, the internal teeth of the threaded holes on the mounting seat may be damaged, which will further cause inconvenience to the installation and disassembly of the hydraulic pump. In view of this, we propose a hydraulic pump with a pressure conversion function. Content of the Utility Model

[0019] Please refer to Figures 1-3 as shown, the present invention provides a technical solution:

[0020] A hydraulic pump with a pressure conversion function includes a hydraulic pump body 1 and a mounting seat 2. A T-shaped mounting support 11 is provided at the bottom of the hydraulic pump body 1. Locking feet 5 are symmetrically and slidably connected to both sides of the T-shaped mounting support 11. A driving seat 4 is slidably connected in the T-shaped mounting support 11 between the two locking feet 5. The top of the driving seat 4 and the top of the locking feet 5 both slide along the top inside of the T-shaped mounting support 11. A screw rod 3 is rotatably connected to the inside of the T-shaped mounting support 11 through a bearing. The screw rod 3 threadedly penetrates through the middle of the driving seat 4, and the front end of the screw rod 3 extends outside the T-shaped mounting support 11 and is fixedly provided with a hand crank 31. Guide surfaces 41 are symmetrically provided on both sides of the driving seat 4. One end of the locking foot 5 close to the driving seat 4 is rotatably connected to a guide roller 6 through a wheel shaft. The guide roller 6 rolls along the guide surface 41. A sliding support 51 is provided at the bottom of the locking foot 5 below the guide roller 6. A slide rod 8 is fixedly connected in the T-shaped mounting support 11 below the driving seat 4. Both ends of the slide rod 8 movably penetrate through the two sliding supports 51. A spring 7 is sleeved on the slide rod 8 between the sliding support 51 and the T-shaped mounting support 11. One end of the spring 7 abuts against the inner side wall of the T-shaped mounting support 11, and the other end of the spring 7 abuts against the sliding support 51. A T-shaped mounting groove 21 is provided at the top of the mounting seat 2. The T-shaped mounting support 11 is in fit connection with the T-shaped mounting groove 21. Support foot grooves 22 are symmetrically provided on both sides of the T-shaped mounting groove 21. One end of the locking foot 5 far from the driving seat 4 is in fit connection with the support foot groove 22. By sliding the T-shaped mounting support 11 into the T-shaped mounting groove 21 and driving the driving seat 4 to move backward by clockwise rotating the screw rod 3, the two locking feet 5 can be pushed to move outward and inserted into the support foot grooves 22, so as to quickly fix the hydraulic pump body 1 on the mounting seat 2. By counterclockwise rotating the screw rod 3 to drive the driving seat 4 to move forward, under the elastic force of the spring 7, the locking feet 5 can be driven to move inward and reset, so that the outer ends of the locking feet 5 are removed from the support foot grooves 22, and the hydraulic pump body 1 can be quickly disassembled from the mounting seat 2, with convenient operation. When installing the hydraulic pump body 1, the T-shaped mounting support 11 can be slid into the T-shaped mounting groove 21 from the front side of the T-shaped mounting groove 21, and the screw rod 3 can be driven to rotate by manually rotating the hand crank 31 clockwise. The rotation of the screw rod 3 can drive the driving seat 4 to move backward. Through the driving seat 4, the two locking feet 5 can be pushed to move outward. At this time, the sliding support 51 moves along the slide rod 8 to compress the spring 7, so that the outer ends of the locking feet 5 are inserted into the support foot grooves 22, and the hydraulic pump body 1 is quickly installed and fixed on the mounting seat 2. By counterclockwise rotating the hand crank 31 to drive the screw rod 3 to rotate, the driving seat 4 can be driven to move forward. At this time, under the elastic force of the spring 7, the locking feet 5 can be driven to move inward and reset, so that the outer ends of the locking feet 5 are removed from the support foot grooves 22, and the T-shaped mounting support 11 can be slid out of the T-shaped mounting groove 21, and the hydraulic pump body 1 can be quickly disassembled from the mounting seat 2.

[0021] On the outer wall of the T-shaped mounting seat 11 above the locking foot 5, an upper positioning strip 9 is fixedly connected. The rear end face of the upper positioning strip 9 is flush with the front end face of the locking foot 5. On the top of the mounting seat 2, lower positioning strips 10 are symmetrically and fixedly connected. The front end face of the lower positioning strip 10 is flush with the front end face of the foot slot 22. Through the cooperation of the upper positioning strip 9 and the lower positioning strip 10, the position of the T-shaped mounting seat 11 sliding into the T-shaped mounting slot 21 can be positioned, so that the locking foot 5 can be smoothly inserted into the foot slot 22 without the need for personnel to continuously adjust the position of the T-shaped mounting seat 11, which is more convenient. During the process of sliding the T-shaped mounting seat 11 into the T-shaped mounting slot 21, push the T-shaped mounting seat 11 and make the upper positioning strip 9 abut against the lower positioning strip 10, then the installation positioning of the T-shaped mounting seat 11 can be completed.

[0022] Working principle: When installing the hydraulic pump body 1, the T-shaped mounting seat 11 can be slid into the T-shaped mounting slot 21 from the front side of the T-shaped mounting slot 21. During the process of sliding the T-shaped mounting seat 11 into the T-shaped mounting slot 21, push the T-shaped mounting seat 11 and make the upper positioning strip 9 abut against the lower positioning strip 10, then the installation positioning of the T-shaped mounting seat 11 can be completed. Then, manually rotate the hand crank 31 clockwise to drive the screw 3 to rotate. The rotation of the screw 3 can drive the driving seat 4 to move backward. Through the driving seat 4, two locking feet 5 can be pushed to move outward. At this time, the sliding seat 51 moves along the sliding rod 8 to compress the spring 7, so that the outer ends of the locking feet 5 are inserted into the foot slots 22, and the hydraulic pump body 1 is quickly installed and fixed on the mounting seat 2. By rotating the hand crank 31 counterclockwise to drive the screw 3 to rotate, the driving seat 4 can be driven to move forward. At this time, under the elastic force of the spring 7, the locking feet 5 can be driven to move inward and reset, so that the outer ends of the locking feet 5 are removed from the foot slots 22, and then the T-shaped mounting seat 11 can be slid out of the T-shaped mounting slot 21, and the hydraulic pump body 1 can be quickly disassembled from the mounting seat 2.
