Description

Technical Field

[0001] The present application relates to the technical field of vane pumps, and in particular to a vane pump for conveying hydraulic medium. Background Art

[0002] A vane pump that transports hydraulic media is a device that converts mechanical energy into pressure energy. It uses the rotation of the vanes in the pump body and the volume change of the pump chamber to achieve liquid suction and compression. It consists of components such as the pump body, the liquid inlet end and the liquid discharge end.

[0003] Currently, the output end of the vane pump is connected to external equipment through a rigid pipe. During the actual installation process, due to the strong rigidity of the rigid pipe, it is difficult to adjust it once installed. This may cause some problems in actual application. For example, when the equipment needs to be moved or repositioned, the fixed rigid pipe may become an obstacle, resulting in insufficient spatial adaptability of the device. Utility Model Content

[0006] Preferably, the pipeline connection adjustment mechanism includes a bellows fixedly connected to the output end away from one end of the vane pump body, and sealing rings are provided at both ends of the bellows.

[0007] Preferably, the end of the bellows away from the output end is fixedly connected to a position-adjusting hard tube, the upper surface of the fixing frame is fixedly connected to a central axis, and the central axis is connected to the axis center of the gear ring frame.

[0008] Preferably, the outer surface of the central shaft is rotatably connected to a gear ring frame, the upper surface of the gear ring frame is fixedly connected to a second retaining platform, and the inner surface of the second retaining platform is fixedly sleeved with the outer surface of the positioning hard tube.

[0009] Preferably, a motor is fixedly mounted on the bottom of the fixing frame, and an output end of the motor is fixedly connected to a drive shaft.

[0010] Preferably, a gear is fixedly sleeved on the outer surface of the drive shaft, and the outer surface of the gear is meshedly connected with the outer surface of the gear ring frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The vane pump for conveying hydraulic medium introduces a pipeline connection adjustment mechanism, so that the angle of the positioning hard pipe can be flexibly adjusted according to actual installation requirements. This greatly improves the adaptability of the vane pump in different installation environments. In particular, when the equipment needs to be moved or repositioned, there is no need to rearrange the hard pipe, which greatly improves the spatial adaptability of the device.

[0013] 2. This vane pump used to transport hydraulic media achieves precise control of the angle of the adjusted hard pipe through the linkage of mechanical structures such as the motor, drive shaft, gears and gear ring frame. This mechanical adjustment method is more stable and reliable than manual adjustment, and reduces connection problems caused by improper human operation. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] See also Figure 1-2 A vane pump for conveying hydraulic medium includes a vane pump body 1, an input end 2 and an output end 3 are respectively provided on the vane pump body 1, the outer surface of the vane pump body 1 is fixedly connected to a fixing frame 4, the outer surface of the fixing frame 4 is fixedly connected to a first retaining platform 5, and the inner surface of the first retaining platform 5 is fixedly sleeved with the outer surface of the output end 3, and a pipeline connection adjustment mechanism is provided on the fixing frame 4.

[0019] Through the above technical solution, during use, the vane pump body 1 transports the hydraulic medium (fluid) liquid into the vane pump body 1 through the input end 2, and then pumped out through the output end 3 to achieve the purpose of transporting the liquid. During this process, the angle of the positioning hard tube 8 can be adjusted through the pipeline connection adjustment mechanism according to actual installation needs.

[0020] Specifically, the pipeline connection adjustment mechanism includes a bellows 6 fixedly connected to the output end 3 away from the end of the vane pump body 1, and sealing rings 7 are provided at both ends of the bellows 6.

[0021] Through the above technical solution, the sealing rings 7 designed at both ends of the bellows 6 are to ensure that the bellows 6 and the output end 3 and the adjustment hard tube 8 are in a good sealing state during the stable communication process.

[0022] Specifically, one end of the bellows 6 away from the output end 3 is fixedly connected to a position-adjusting hard tube 8 , and the upper surface of the fixing frame 4 is fixedly connected to a central shaft 9 .

[0023] Through the above technical solution, the positioning hard tube 8 will drive the bellows 6 to deform during the process of rotating along with the central axis 9.

[0024] Specifically, the outer surface of the central shaft 9 is rotatably connected to the gear ring frame 10 , the upper surface of the gear ring frame 10 is fixedly connected to the second retaining platform 11 , and the inner surface of the second retaining platform 11 is fixedly sleeved with the outer surface of the positioning hard tube 8 .

[0025] Through the above technical solution, the second retaining platform 11 plays a role in stabilizing the position of the hard tube 8, and the gear ring frame 10 drives the second retaining platform 11 to perform synchronous circular motion during the rotation process.

[0026] Specifically, a motor 12 is fixedly mounted on the bottom of the fixing frame 4 , and an output end of the motor 12 is fixedly connected to a driving shaft 13 .

[0027] Through the above technical solution, when the motor 12 drives the driving shaft 13 to rotate, the gear 14 will be linked to rotate, and during this period, the gear ring frame 10 meshing with the gear 14 will rotate accordingly.

[0028] Specifically, a gear 14 is fixedly sleeved on the outer surface of the driving shaft 13 , and the outer surface of the gear 14 is meshedly connected with the outer surface of the gear ring frame 10 .

[0029] Through the above technical solution, the gear 14 cooperates with the gear ring frame 10 to convert the rotation of the drive shaft 13 into the deflection of the position of the adjustment hard tube 8.

[0030] Working principle: During the use of the vane pump body 1, the liquid conveying the hydraulic medium (fluid) enters the vane pump body 1 through the input end 2, and is then pumped out through the output end 3 (after the liquid is pumped into the output end 3, it will be connected to the external equipment through the pipeline connection adjustment mechanism) to achieve the purpose of conveying the liquid (during which the flow rate and direction of the liquid change). During this process, the angle of the adjustment hard tube 8 can be adjusted through the pipeline connection adjustment mechanism according to actual installation needs to adapt to the spatial adaptability of the vane pump. That is, at this time, the motor 12 can be turned on to drive the drive shaft 13 to rotate, and then the gear 14 can be linked to rotate. Since the gear 14 is meshed and connected with the gear ring frame 10, the gear 14 will drive the gear ring frame 1 during the rotation process. 0 rotates along the central axis 9, and the second retaining platform 11 on the upper surface of the gear ring frame 10 will make a circular motion accordingly, that is, the position of the adjustment hard tube 8 is adjusted. In this process, the bellows 6 is affected by the position deflection of the adjustment hard tube 8, and will produce corresponding deformation and expansion to adapt to the position deflection of the adjustment hard tube 8 until the adjustment hard tube 8 is adjusted to a suitable angle. During this period, the liquid can be pumped into the adjustment hard tube 8 through the output end 3 through the bellows 6 and finally into the external equipment, thereby achieving the effect of allowing the pipeline angle to be adjusted during or after installation, ensuring the optimal pipeline layout and connection efficiency. This flexibility enables the vane pump to more easily adapt to various complex installation scenarios.
