Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plunger pumps, and particularly relates to a high-pressure plunger pump for special oilfield vehicles. Background Technique
[0002] The plunger pump is an important component of the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder block to change the volume of the sealed working chamber to achieve oil suction and oil pressure operations. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency, and convenient flow regulation, and is widely used in special oilfield vehicles.
[0003] The utility model patent with the patent authorization announcement number CN 217354730 U discloses a three-cylinder high-pressure plunger pump, including a plunger pump main body. Docking ends are arranged around the lower end of the plunger pump main body, and an installation structure is arranged at the lower end of the docking end. The installation structure includes a fixed bottom plate. Installation chutes are opened at both ends on one side of the fixed bottom plate, and sliders are slidably arranged in the installation chutes.
[0004] However, there are still some disadvantages in the actual use of the above-mentioned plunger pump. The more obvious one is that the limit block and the fixed bottom plate are separately arranged. Therefore, after the limit block is disassembled, it still needs to be manually taken out and placed aside, which is inconvenient in actual use. In addition, during the installation process of the limit block, the operator needs to manually align and insert the limit block and the limit groove in the vertical direction. Since it is a manual operation, there is also a certain degree of operation difficulty.
[0005] Therefore, it is very necessary to invent a high-pressure plunger pump for special oilfield vehicles to solve the above problems. Content of the Utility Model
[0006] The purpose of the present utility model is to provide a high-pressure plunger pump for oilfield special vehicles. By providing a convenient blocking mechanism, after connecting the high-pressure plunger pump body with the slider and sliding the slider to the corresponding position outside the T-shaped slide rail, the end of the blocking plate can be pulled, so that the blocking plate rotates around the pin shaft. As the blocking plate rotates continuously, the bottom of the blocking plate contacts the inclined surface at the end of the locking rod. Subsequently, as the blocking plate continues to move, the blocking plate pushes the locking rod through the inclined surface, so that the locking rod drives the end plate to move outward and stretches the return spring. Subsequently, when the blocking plate rotates to the horizontal state, the locking rod is collinear with the locking groove. At this time, the stretched return spring drives the locking rod to insert into the inner side of the locking groove, thereby completing the locking of the blocking plate. At this time, the blocking plate forms a block for the adjacent slider to ensure the stability of the high-pressure plunger pump body. Subsequently, when it is necessary to slide out and disassemble the slider, the end plate is pulled outward, and the end plate drives the locking rod to move out from the inner side of the locking groove. At this time, the torsion spring drives the blocking plate to rotate from the horizontal state to the vertical state, thereby quickly blocking the slider, so as to solve the problem that the limit stop and the fixed bottom plate are separately arranged in the above-mentioned background technology. Therefore, after the limit stop is disassembled, it still needs to be manually taken out and placed aside, which is inconvenient in actual use. In addition, during the installation process of the limit stop, the operator needs to manually align and insert the limit stop and the limit groove in the vertical direction. Since it is a manual operation, there is also a certain degree of operation difficulty.

The base is welded to the oilfield special vehicle, the chute is opened at the top of the base, and the T-shaped slide rail is fixedly arranged at the inner bottom of the chute.

[0014] The high-pressure plunger pump for special oilfield vehicles according to at least one embodiment of the present disclosure, the convenient blocking mechanism further includes a locking groove, and the locking groove is opened at the outer end of the blocking plate.

[0016] The high-pressure plunger pump for special oilfield vehicles according to at least one embodiment of the present disclosure, the convenient blocking mechanism further includes an inclined surface, an end plate and a return spring, the inclined surface is opened at the inner end of the locking rod, the end plate is fixedly disposed at the outer end of the locking rod, and the return spring is sleeved outside the locking rod and fixedly connected between the locking groove and the end plate.
[0017] The technical effects and advantages of the present utility model:
[0018] The present utility model is provided with a convenient blocking mechanism, so that after the connection between the high-pressure plunger pump body and the slider is completed and the slider is slid to the corresponding position outside the T-shaped slide rail, the end of the blocking plate is pulled, and then the blocking plate rotates around the pin shaft. As the blocking plate rotates continuously, the bottom of the blocking plate contacts the inclined surface at the end of the locking rod. Subsequently, as the blocking plate continues to move, the blocking plate pushes the locking rod through the inclined surface, so that the locking rod drives the end plate to move outwards and stretches the return spring. Subsequently, when the blocking plate rotates to the horizontal state, the locking rod and the locking groove are collinear. At this time, the stretched return spring drives the locking rod to insert into the inner side of the locking groove, thereby completing the locking of the blocking plate. At this time, the blocking plate forms a block for the adjacent slider to ensure the stability of the high-pressure plunger pump body. Subsequently, when the slider needs to be slid out and disassembled, the end plate is pulled outwards, and the end plate drives the locking rod to move out of the inner side of the locking groove. At this time, the torsion spring drives the blocking plate to rotate from the horizontal state to the vertical state, thereby quickly blocking the slider. Compared with the same type of device in the prior art, the convenient blocking mechanism and the base in the present utility model are integrally provided, and when forming a block, it is not necessary to insert the blocking plate, which reduces the operation difficulty and is more convenient in actual use.

[0027] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "over", "upper", and "side (e.g., as in "side wall")" to describe the relationship between one component and another (other) component as shown in the accompanying drawings. In addition to the orientation depicted in the accompanying drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the accompanying drawings is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the said other component or feature.

In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptive terms used herein are to be interpreted accordingly.
[0028] Figure 1 is a schematic diagram of the overall structure of a high-pressure plunger pump for an oilfield special vehicle according to an embodiment of the present disclosure.
[0029] AsFigures 1 - 3 As shown, the high-pressure plunger pump of the special oilfield vehicle of the present disclosure may include components such as a high-pressure plunger pump body 1, a sliding mounting mechanism 2, and a convenient blocking mechanism 3.
[0030] Figure 2 It is a schematic structural diagram of the sliding mounting mechanism 2 of the high-pressure plunger pump of the special oilfield vehicle according to an embodiment of the present disclosure.
[0031] As Figure 2 shown, in a preferred embodiment, the sliding mounting mechanism 2 includes a base 21, a chute 22, a T-shaped slide rail 23, a slider 24, and a mounting hole 25. Among them, the base 21 is welded to the special oilfield vehicle, the chute 22 is opened at the top of the base 21, the T-shaped slide rail 23 is fixedly arranged at the inner bottom of the chute 22, the slider 24 is slidably arranged inside the chute 22 and is slidably sleeved outside the T-shaped slide rail 23, and the mounting hole 25 is penetrated through the top of the slider 24.
[0032] Thus, it is convenient to install the four sliders 2 at the corresponding positions at the bottom of the high-pressure plunger pump body 1 through bolts respectively. Then, the high-pressure plunger pump body 1 is lifted and moved, so that the high-pressure plunger pump body 1 drives the slider 24 into the inner side of the chute 22 and is sleeved outside the T-shaped slide rail 23. Then, the high-pressure plunger pump body 1 continues to move, so that the multiple sliders 2 reach the installation position.
[0033] Figure 3 It is a schematic structural diagram of the convenient blocking mechanism 3 of the high-pressure plunger pump of the special oilfield vehicle according to an embodiment of the present disclosure.
[0034] As Figure 3 shown, in the present disclosure, the convenient blocking mechanism 3 includes a first side plate 31, a blocking plate 32, a torsion spring 33, a locking groove 34, a second side plate 35, a locking rod 36, an inclined surface 37, an end plate 38, and a return spring 39. Among them, the first side plate 31 is fixedly arranged at one end of the top of the base 21, the blocking plate 32 is located on the right side of the first side plate 31 and is rotatably connected to the first side plate 31 through a pin shaft, the torsion spring 33 is fixedly connected between the first side plate 31 and the torsion spring 33, the locking groove 34 is opened at the outer end of the blocking plate 32, the second side plate 35 is fixedly arranged at the other end of the top of the base 21, the locking rod 36 slides through the second side plate 35, the inclined surface 37 is opened at the inner end of the locking rod 36, the end plate 38 is fixedly arranged at the outer end of the locking rod 36, and the return spring 39 is sleeved outside the locking rod 36 and is fixedly connected between the locking groove 34 and the end plate 38.
[0035] Thus, after the connection between the high-pressure plunger pump body 1 and the slider 24 is completed and the slider 24 is slid to the corresponding position outside the T-shaped slide rail 23, the end of the baffle 32 is pulled, so that the baffle 32 rotates around the pin shaft. As the baffle 32 rotates continuously, the bottom of the baffle 32 contacts the inclined surface 37 at the end of the locking rod 36. Subsequently, as the baffle 32 continues to move, the baffle 32 pushes the locking rod 36 through the inclined surface 37, so that the locking rod 36 drives the end plate 38 to move outward and stretches the return spring 39. Subsequently, when the baffle 32 rotates to the horizontal state, the locking rod 36 is collinear with the locking groove 34. At this time, the stretched return spring 39 drives the locking rod 36 to insert into the inner side of the locking groove 34, thus completing the locking of the baffle 32. At this time, the baffle 32 forms a block for the adjacent slider 24 to ensure the stability of the high-pressure plunger pump body 1. Subsequently, when the slider 24 needs to be slid out and disassembled, the end plate 38 is pulled outward. The end plate 38 drives the locking rod 36 to move out from the inner side of the locking groove 34. At this time, the torsion spring 33 drives the baffle 32 to rotate from the horizontal state to the vertical state, thus quickly blocking the slider 24.
