Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a pressure injection and oil filling device. Background Art

[0002] In existing construction machinery equipment, most of the front and rear axles adopt a suspended cylinder shock absorber device to shock-absorb the vehicle body. This device generally operates in a way of hydraulic plus nitrogen. When the suspended cylinder is repaired and inspected, some of its structures need to be disassembled, and the internal hydraulic oil will be discharged. Then, after the repair and inspection, hydraulic oil needs to be re-input into the suspended cylinder. However, when inputting hydraulic oil, it is generally input in an infusion manner, and the flow rate of the hydraulic oil during the input process is slow, resulting in a long filling time and affecting the timeliness of equipment recovery.

[0003] Based on the above situation, it is necessary to design a pressure injection and oil filling device to solve the above problems. Summary of the Utility Model

[0004] The utility model provides a pressure injection and oil filling device to solve the problem of low oil injection efficiency inside the suspended cylinder in the prior art.

[0005] The technical problems solved by the utility model are realized by adopting the following technical solutions:

[0006] A pressure injection and oil filling device includes a movable base and a cylinder body connected to the base, and further includes: a pump body mechanism connected to the base and used to drive the flow of oil; an oil storage chamber located inside the cylinder body, which is used to receive and store oil, and the output end of the oil storage chamber is connected to the input end of the pump body mechanism through a first channel; an oil guiding chamber located inside the cylinder body, the input end of the oil guiding chamber is connected to the output end of the pump body mechanism through a second channel, and the output end of the oil guiding chamber is connected to the input end of the suspended cylinder through a connecting mechanism.

[0007] Preferably, the pump body mechanism includes a pump body connected to the base, a squeezing chamber opened inside the pump body, and a piston member sealingly and slidably connected to the squeezing chamber, and one end of the piston member extends outside the squeezing chamber.

[0008] Preferably, the pump body mechanism further includes a first articulated rod fixedly connected to one end of the piston member, a second articulated rod hinged to the pump body, and a third articulated rod with two ends respectively hinged to the second articulated rod and the first articulated rod.

[0009] Preferably, the pump body mechanism further includes two one-way flow components, the two one-way flow components are respectively connected to the first channel and the second channel, and each one-way flow component includes a compression spring and a sphere, and the sphere is connected to one end of the compression spring.

[0010] Preferably, the connecting mechanism includes two one-way valves and a conduit. The input end of one of the one-way valves is connected to the output end of the oil guiding chamber, and the output end of the other one-way valve is used to be movably connected to the input end of the suspension cylinder. The conduit is connected between the two one-way valves.

[0011] Preferably, a tank body is movably installed on the base, and the output end of the tank body is connected to the input end of the oil storage chamber.

[0012] The beneficial effects of the present utility model are as follows: By using the pump body mechanism, the oil liquid located inside the oil storage chamber is introduced into the oil guiding chamber until the oil guiding chamber is filled with oil liquid. Then, the output end of the connecting mechanism is connected to the input end of the suspension cylinder to be added. Next, by using the pump body mechanism, the oil liquid located inside the oil storage chamber continuously flows into the oil guiding chamber, and the oil liquid inside the oil guiding chamber is continuously introduced into the suspension cylinder through the connecting mechanism.

Specific implementation mode

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0022] Refer to Figures 1-6 As shown, a pressure injection and oil filling device includes a movable base 1 and a cylinder block 2 connected to the base 1, and also includes a pump body 5 mechanism, an oil storage chamber 3 and an oil guiding chamber 4. The pump body 5 mechanism is connected to the base 1 and is used to drive the flow of oil; the oil storage chamber 3 is located inside the cylinder block 2, and the oil storage chamber 3 is used to receive and store oil. The output end of the oil storage chamber 3 is connected to the input end of the pump body 5 mechanism through the first channel 30; the oil guiding chamber 4 is located inside the cylinder block 2, and the input end of the oil guiding chamber 4 is connected to the output end of the pump body 5 mechanism through the second channel 40. The output end of the oil guiding chamber 4 is connected to the input end of the hanging cylinder through a connecting mechanism.

[0023] During use, the oil storage chamber 3 will be filled with the oil to be used. Then, the pump body 5 mechanism is used to draw out the oil inside the oil storage chamber 3 through the first channel 30, and then introduce it into the oil guiding chamber 4 through the second channel 40. As the oil in the oil guiding chamber 4 gradually increases, the oil will gradually be squeezed towards the output end of the oil guiding chamber 4. Then, the connecting mechanism is used to connect the output end of the connecting mechanism to the input end of the hanging cylinder to be added. Then, the pump body 5 structure is continued to be used to squeeze the oil inside the oil guiding chamber 4 into the hanging cylinder through the connecting mechanism. Compared with the existing infusion type of adding hydraulic oil, this method can accelerate the import and export speed of hydraulic oil, thereby improving the efficiency of adding oil into the hanging cylinder.

[0024] When the oil storage chamber 3 is in use, since the first channel 30 is located at the bottom of the oil storage chamber 3, after the oil is deposited, the air will be discharged to the upper part, so the influence of air on the oil output is reduced. When the oil guiding chamber 4 is in use, after receiving the oil output by the pump body 5 mechanism, the oil inside it will be continuously squeezed and compacted. When adding oil into the hanging cylinder, the oil squeezed together inside the oil guiding chamber 4 will be timely introduced into the hanging cylinder through the connecting mechanism.

[0025] Secondly, in the prior art, the suspension cylinder is sometimes disassembled as a whole for addition, which involves a large workload and a heavy weight, and there are safety risks during disassembly and transportation. The technical solution in the present invention can effectively avoid this problem when used. The technical solution is convenient and fast to use, and easy to move. Next, when the technical solution is used, the amount of oil added can be effectively controlled, effectively avoiding the wear of the suspension cylinder body 2 due to failure to meet the filling standard.

[0026] Reference Figure 5 As shown, the pump body 5 mechanism includes a pump body 5 connected to the base 1, an extrusion chamber 6 opened inside the pump body 5, and a piston member 7 sealingly and slidably connected to the extrusion chamber 6, one end of the piston member 7 extends to the outside of the extrusion chamber 6, or the piston member 7 slides upward inside the extrusion chamber 6, thereby making the internal space of the extrusion chamber 6 larger, and then the oil located inside the oil storage tank 3 will be drawn into the extrusion chamber 6, and when the piston member 7 slides downward inside the extrusion chamber 6, the internal space of the extrusion chamber 6 becomes smaller, and then the oil located inside the extrusion chamber 6 will be squeezed into the oil guide tank 4, and so on and so forth, the purpose of the pump body 5 mechanism to guide the oil inside the oil storage chamber into the oil guide tank 4 can be achieved.

[0027] Reference Figures 1-2 As shown, further, the pump body 5 mechanism also includes an articulated rod 1 8 fixedly connected to one end of the piston member 7, an articulated rod 2 9 articulated to the pump body 5, and an articulated rod 3 10 whose two ends are respectively articulated to the articulated rod 2 9 and the articulated rod 1 8, a sleeve 101 is fixedly connected to the articulated rod 3 10, and the sleeve 101 facilitates the insertion of a tool (not shown in the figure) and prying the movement of the articulated rod 3 10. The above structure facilitates the power input for the sliding of the piston member 7. When one end of the articulated rod 3 10 is pressed down and tilted, the articulated rod 1 8, the articulated rod 2 9 and the articulated rod 3 10 will move at the hinges, so that the tool can drive the piston member 7 to slide back and forth up and down.

[0028] When the oil storage bin 3 is in use, the space inside it is limited, which leads to the limited oil storage capacity inside it. Therefore, in order to facilitate the uninterrupted supply of oil inside the oil storage bin 3 during use, a tank body 15 is movably installed on the base 1. The output end of the tank body 15 is connected to the input end of the oil storage bin 3. The tank body 15 is provided with a tank cover 150. The tank body 15 is in a state that can be opened at any time, so that oil can be added to the inside at any time. When adding, the oil is deposited at the bottom of the tank body 15, and then the output end of the tank body 15 and the output end of the oil storage bin 3 are closed. Therefore, there is no need to worry about impurities mixing into the oil storage bin 3 after opening the tank cover 150.

[0029] Reference Figures 5-6As shown, further, the pump body 5 mechanism further includes two one-way flow components, which are respectively connected to the first channel 30 and the second channel 40. Each one-way flow component includes a compression spring 11 and a sphere 12. The sphere 12 is connected to one end of the compression spring 11. The two compression springs 11 in the two one-way flow components are respectively connected to the first channel 30 and the second channel 40. The first channel 30 and the second channel 40 have different inner diameters according to the movement path of the sphere 12, and the contact between the sphere 12 and the inner side wall of the channel is in close contact, having tightness.

[0030] Referring to Figures 4-5 As shown, the connecting mechanism includes two one-way valves 13 and a conduit 14. The input end of one one-way valve 13 is connected to the output end of the oil guide chamber 4, and the output end of the other one-way valve 13 is used for movably connecting to the input end of the suspension cylinder. The conduit 14 is connected between the two one-way valves 13. The one-way valve 13 in this technical solution is a prior art structure and will not be elaborated. The one-way valve 13 connected to the suspension cylinder prevents the oil in the suspension cylinder from flowing back into the conduit 14, while the one-way valve 13 connected to the oil guide chamber 4 prevents the oil in the conduit 14 from flowing back into the oil guide chamber 4, reducing the additional internal pressure of the oil guide chamber 4. It also prevents the oil remaining in the conduit 14 from splashing out when the connecting mechanism is removed. A conical connecting piece 131 is provided at the output end of the one-way valve 13 connected to the suspension cylinder, which is convenient for mating connection with the input end of the suspension cylinder and is a prior art structure.

[0031] Finally, referring to Figure 1 As shown, rollers 16 for facilitating the movement of the base 1 are installed below the base 1, which facilitates the use of the device.
