[0001] The invention relates to the technical field of oil extraction, and in particular to a hydraulic multifunctional fracturing pump. Background Art

[0002] In the field of oil extraction, oil needs to be fractured. Fracturing refers to the use of hydraulic force to form cracks in oil and gas layers. By artificially creating cracks in the stratum, the flow environment of oil underground is improved, and the output of oil wells is increased. It plays an important role in improving the flow conditions at the bottom of the oil well, slowing down the interlayer and improving the utilization of the oil layer. Fracturing requires the use of an oil fracturing pump, and traditional fracturing pumps have a certain shape of the gear case and the motor case. When the gear case and the motor housing are directly connected, there is a shape mismatch, resulting in a poor seal.

[0003] In the prior art, by setting a limit groove, the second seal and the matching first seal are accurately positioned. The installation of the first seal and the second seal can be completed by only bolting the first sealing plate on the inner side of the first sealing tube, thereby making the installation operation simple and convenient and avoiding poor sealing caused by improper installation operation.

[0004] However, in the above-mentioned prior art, the fracturing pump generates vibration when in use, and no buffer is provided for the vibration, which may easily lead to damage of the fracturing pump. Summary of the invention

[0005] The purpose of the present invention is to provide a hydraulic multifunctional fracturing pump, which solves the problem in the prior art that the fracturing pump generates vibration during use and is not buffered, which easily leads to damage of the fracturing pump.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0024] First embodiment:

[0025] See also Figures 1 to 4 The present invention provides a hydraulic multifunctional fracturing pump, comprising a fracturing pump body 101, a plurality of feed pipes 102, a plurality of discharge pipes 103 and a buffer assembly, wherein the buffer assembly comprises a plurality of feed units, a plurality of buffer slide bars 104, a plurality of shock-absorbing pads 105, a plurality of buffer cylinders 106, a support plate 107, a plurality of rebound units, a support seat 108, a plurality of sliders 109, a plurality of transverse buffer units and a plurality of anti-slip pads 111, the fracturing pump body 101 and the support seat 108 both have a slide groove 110, the feed unit comprises a feed channel 112, a telescopic hose 113 and a mounting flange 114, the rebound unit comprises a first buffer hydraulic rod 115 and a first spring 116, the transverse buffer unit comprises two second buffer hydraulic cylinders 117, two second springs 118, two connecting blocks 119, a first telescopic rod 120 and a third spring 121.

[0026] In this embodiment, the fracturing pump body 101 vibrates, and at this time the buffer slide rod 104 slides in the buffer cylinder 106, and at the same time the shock absorbing pad 105 can contact the inner wall of the buffer cylinder 106 to provide shock absorption. When the buffering reaches the limit, the support plate 107 continues to be pushed downward to provide a buffering effect through the rebound unit. At the same time, when the fracturing pump body 101 moves laterally, the second buffer hydraulic rod performs buffering and shock absorption, and at the same time the slider 109 slides in the slide groove 110, thereby converting the original rotation direction of the fracturing pump body 101 into lateral movement, thereby achieving a buffering and shock absorption effect.

[0027] Among them, multiple feed pipes 102 and multiple discharge pipes 103 are sequentially arranged on both sides of the fracturing pump body 101, the fracturing pump body 101 and the support seat 108 both have a slide groove 110, multiple feed units are sequentially arranged on the fracturing pump body 101, multiple buffer slide bars 104 are sequentially arranged below the fracturing pump body 101, multiple shock-absorbing pads 105 are respectively arranged below the corresponding buffer slide bars 104, multiple buffer cylinders 106 are sequentially arranged above the support plate 107, multiple buffer slide bars 104 are respectively slidably connected to the corresponding buffer cylinders 106, multiple rebound units are sequentially arranged between the support plate 107 and the support seat 108, multiple sliders 109 are respectively slidably connected to the corresponding slide grooves 110, and multiple sliders 109 are connected through the transverse buffer unit. The fracturing pump body 101 is placed at the place of use by relying on the support seat 108, and the feed unit is connected to the feed pipe 102, and then the discharge pipe 103 discharges the medium. When the fracturing pump body 101 is working, it vibrates. At this time, the buffer slide bar 104 slides in the buffer cylinder 106, and the shock-absorbing pad 105 can contact the inner wall of the buffer cylinder 106 to provide shock absorption. When the buffering reaches the limit, the support plate 107 continues to be pushed downward to provide a buffering effect through the rebound unit. At the same time, when the fracturing pump body 101 moves laterally due to vibration, the slider 109 slides in the slide groove 110, and relies on the lateral buffer unit for lateral buffering.

[0028] Secondly, the plurality of anti-skid pads 111 are fixedly connected to the support base 108 and are sequentially distributed below the support base 108. The anti-skid pads 111 can prevent the support base 108 from slipping and improve the overall installation stability.

[0029] At the same time, one end of the feed channel 112 is connected to the feed pipe 102, and both ends of the telescopic hose 113 are respectively connected to the mounting flange 114 and the other end of the feed channel 112. The mounting flange 114 is connected to the conveying source, and then when the fracturing pump body 101 vibrates and moves, the telescopic hose 113 can follow the movement, and finally the conveying medium reaches the feed pipe 102 through the telescopic hose 113 and the feed channel 112.

[0030] In addition, the two ends of the first buffer pressure rod 115 are respectively fixedly connected to the support seat 108 and the support plate 107, and the two ends of the first spring 116 are respectively movably connected to the support seat 108 and the support plate 107, and the first spring 116 is sleeved on the outside of the first buffer pressure rod 115. When the support plate 107 moves downward, the first buffer pressure rod 115 plays a role of buffering and shock absorption. After the shock absorption is completed, the first spring 116 drives the support plate 107 to rebound. At the same time, due to the function of the first buffer pressure rod 115, the rebound speed will not be too fast, so as to avoid the fracturing pump body 101 from bouncing up.

[0031] Finally, the two ends of the two second buffer pressure rods are fixedly connected to the slider 109 and the connecting block 119 respectively, the two ends of the two second springs 118 are movably connected to the slider 109 and the connecting block 119 respectively, the second springs 118 are sleeved on the outside of the second buffer pressure rod, the two ends of the first telescopic rod 120 are fixedly connected to the corresponding connecting block 119 respectively, the two ends of the third spring 121 are movably connected to the corresponding connecting block 119 respectively, and the third spring 121 is sleeved on the outside of the first telescopic rod 120. When the fracturing pump body 101 moves laterally, the second buffer hydraulic rod performs buffering and shock absorption, and the slider 109 slides in the slide groove 110, thereby converting the original rotation direction of the fracturing pump body 101 into lateral movement, thereby achieving a buffering and shock absorption effect. At the same time, after the buffering is completed, the second spring 118 rebounds to drive the fracturing pump body 101 to reset. When the fracturing pump body 101 moves downward, the first telescopic rod 120 follows the movement, and relying on the connection between the first telescopic rod 120 and the two connecting blocks 119, the upper and lower sliders 109 can move synchronously. The third spring 121 can assist the fracturing pump to move upward and rebound, so as to avoid the fracturing pump body 101 being too heavy and unable to be completely reset.

[0032] When using a hydraulic multifunctional fracturing pump of the present embodiment, the fracturing pump body 101 is placed at the place of use by relying on the support seat 108, and is connected to the conveying source by relying on the mounting flange 114. Then, when the fracturing pump body 101 vibrates and moves, the telescopic hose 113 can follow the movement, and finally the conveying medium reaches the feed pipe 102 through the telescopic hose 113 and the feed channel 112, and then the discharge pipe 103 discharges the medium. When the fracturing pump body 101 vibrates during operation, the buffer slide bar 104 slides in the buffer cylinder 106, and the shock-absorbing pad 105 can contact the inner wall of the buffer cylinder 106 to provide shock absorption. When the buffering reaches the limit, the support plate 107 continues to be pushed downward to provide a buffering effect through the rebound unit. At the same time, when the fracturing pump body 101 moves laterally, the second buffer The pressure rod performs buffering and shock absorption, and at the same time, the slider 109 slides in the slide groove 110, thereby converting the original rotation direction of the fracturing pump body 101 into lateral movement to achieve a buffering and shock absorption effect. At the same time, after the buffering is completed, the second spring 118 rebounds to drive the fracturing pump body 101 to reset. When the fracturing pump body 101 moves downward, the first telescopic rod 120 follows the movement. Relying on the connection between the first telescopic rod 120 and the two connecting blocks 119, the upper and lower sliders 109 can move synchronously. The third spring 121 can assist the fracturing pump to move upward and rebound, so as to avoid the fracturing pump body 101 being too heavy and unable to be completely reset. Through the above-mentioned structural setting, the vibration of the fracturing pump body 101 can be buffered in multiple directions, so as to avoid deformation and damage of the outer shell after forced fixation by bolts, thereby improving the service life of the fracturing pump body 101.

[0033] Second embodiment:

[0034] Based on the first embodiment, please refer to Figure 5 The present invention provides a hydraulic multifunctional fracturing pump, which also includes a plurality of dustproof components, wherein the dustproof components include two sealing plates 201 , two second telescopic rods 202 and two fourth springs 203 .

[0035] In this embodiment, the sealing plate 201 closes the feed channel 112 under the action of the fourth spring 203, but the elasticity of the fourth spring 203 is relatively low, and it is sufficient that the sealing plate 201 can close the feed channel 112. When a medium flows in the feed channel 112, the medium will break open the sealing plate 201, so that the feed channel 112 opens.

[0036] Wherein, a plurality of the dustproof components are respectively arranged on the corresponding feed channels 112. The dustproof components can prevent dust and foreign matter from entering the feed pipe 102 when the feed channel 112 is not in use.

[0037] Secondly, the two sealing plates 201 are both rotatably connected to the feed channel 112 and symmetrically distributed inside the feed channel 112. The two ends of the second telescopic rod 202 are rotatably connected to the inner wall of the feed channel 112 and the sealing plate 201, respectively. The two ends of the fourth spring 203 are movably connected to the inner wall of the feed channel 112 and the sealing plate 201, respectively. The fourth spring 203 is sleeved on the outside of the second telescopic rod 202. Under the action of the fourth spring 203, the sealing plate 201 closes the feed channel 112, but the elasticity of the fourth spring 203 is relatively low, and it is sufficient that the sealing plate 201 can close the feed channel 112. When a medium flows in the feed channel 112, the medium will flush the sealing plate 201, so that the feed channel 112 is opened. After the medium flows away, the sealing plate 201 continues to rebound and reset, and the second telescopic rod 202 assists in movement to improve stability.

[0038] When using a hydraulic multifunctional fracturing pump of the present embodiment, the sealing plate 201 closes the feed channel 112 under the action of the fourth spring 203, but the elasticity of the fourth spring 203 is relatively low, and it is sufficient for the sealing plate 201 to be able to close the feed channel 112. When a medium flows in the feed channel 112, the medium will flush the sealing plate 201, so that the feed channel 112 is opened. After the medium flows away, the sealing plate 201 continues to rebound and reset, and at the same time, the second telescopic rod 202 assists in movement to improve stability. Through the above-mentioned structural arrangement, dust and foreign matter can be prevented from entering the feed pipe 102 when the feed channel 112 is not in use.

[0041] Based on the second embodiment, please refer to Figure 6 The present invention provides a hydraulic multifunctional fracturing pump, which also includes a plurality of control components. The control components include a sealing ring 301, a valve 302, a rotating shaft 303, a turning handle 304 and a threaded rod 305.

[0042] In this embodiment, the sealing ring 301 seals the gap between the valve 302 and the feed channel 112 to prevent leakage. The handle 304 is rotated to drive the shaft 303 to rotate, so that the shaft 303 drives the valve 302 to rotate, and the flow rate is adjusted to reach an appropriate size.

[0043] Wherein, a plurality of control components are respectively arranged on the corresponding feed channels 112. The control components can control the flow rate of the medium in the feed channel 112.

[0044] Secondly, the sealing ring 301 is fixedly connected to the feed channel 112 and is located inside the feed channel 112. The valve 302 and the sealing ring 301 are adapted to each other.

The feed channel 112 has multiple second threaded holes 307. The threaded rod 305 is adapted to each other with the first threaded hole 306 and the second threaded hole 307. The sealing ring 301 seals the gap between the valve 302 and the feed channel 112 to prevent leakage. The handle 304 is turned to drive the shaft 303 to rotate, so that the shaft 303 drives the valve 302 to rotate, and the flow rate is adjusted. After reaching the appropriate flow rate, the threaded rod 305 is turned to cooperate with the first threaded hole 306, and then moved downward and screwed into the second threaded hole 307 to complete the fixation of the shaft 303 and the valve 302.
