Description

Technical Field

[0001] The utility model relates to the technical field of plunger pump accessories, in particular to an accessory for an open ultra-high pressure plunger pump. Background Art

[0002] An open ultra-high-pressure plunger pump is a mechanical device that can compress ordinary liquid into high-pressure liquid. Gears are one of the accessories of radial piston pumps. The rotation of the plunger is mainly driven by gears to achieve the suction and discharge of fluids.

[0003] The existing gears are basically installed on the outside of the transmission shaft. When the gears are engaged for a long time and the gear blocks are severely worn and need to be disassembled and replaced, the transmission shaft usually needs to be disassembled and replaced at the same time, and the gears cannot be disassembled and replaced separately, which increases the subsequent disassembly and replacement costs. In order to overcome the above defects, the existing technology 1 (application number CN202123319933.1, application date 2021-12-27

[0004] (Chinese patent) In a multi-speed gear transmission shaft, when the spring rebounds, the two blocks can be embedded in the slot, and then the gear body can be installed by cooperating with the fixing component. The installation is very convenient and can be completed by one person. The installation does not take a lot of time, and the labor intensity can be greatly reduced. It is also very convenient to maintain and replace the gear body in the later stage, which can reduce the cost of maintenance. Although the existing technology can realize the separate disassembly and replacement of gears, when the gears are disassembled, assembled and replaced, no auxiliary disassembly mechanism is provided to assist the staff in quickly disassembling and replacing the gears, which makes the disassembly and assembly of the gears by the staff very time-consuming and labor-intensive, and has poor practicality.

[0005] Therefore, we proposed accessories for open ultra-high pressure plunger pumps that can solve the above problems well. Utility Model Content

[0006] The purpose of the utility model is to provide an accessory for an open ultra-high pressure plunger pump, so as to solve the problem raised in the above background technology that when gears are disassembled and replaced on the current market, there is no auxiliary disassembly and assembly mechanism to assist the staff in quickly disassembling and replacing the gears, which makes the disassembly and assembly of the gears by the staff very time-consuming and labor-intensive, and has poor practicality.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an accessory for an open ultra-high-pressure plunger pump, comprising a transmission shaft and a driving gear, wherein the driving gear passes through the mounting seat on the top outside of the transmission shaft, and the diameter of the transmission shaft is smaller than the diameter of the driving gear; the top front and rear sides of the transmission shaft are slotted with moving blocks slidingly installed therethrough, and the outer end screws of the two moving blocks are screwed with positioning rods, and the two positioning rods are symmetrically arranged about the transverse center line of the transmission shaft, and the tops of the two positioning rods are fitly connected to the front and rear sides of the bottom of the driving gear.

[0008] Preferably, mounting rods are provided in grooves on the front and rear sides of the top of the transmission shaft, and moving blocks are slidably connected to the outer sides of the two mounting rods.

[0009] Preferably, an extrusion spring is wound around the outer sides of the two mounting rods, and the two extrusion springs have the same structure, and the top ends of the two extrusion springs are connected to a moving block.

[0010] Preferably, positioning rods are screwed onto the front and rear sides of the transmission shaft, and the two positioning rods are symmetrically arranged about the transverse center line of the transmission shaft, and the top outer sides of the two positioning rods are fitted with driving gears.

[0011] Preferably, the left and right sides of the top of the transmission shaft are slotted with limit blocks that are slidably installed, and the outer sides of the two limit blocks are inclined, and the outer sides of the two limit blocks are engaged and connected to the limit slots, and the two limit slots are symmetrically opened on both sides of the inside of the driving gear.

[0012] Preferably, return springs are provided in the slots on both sides of the top of the transmission shaft, and the two return springs have the same structure, and the outer ends of the two return springs are connected to limit blocks.

[0013] Preferably, a shift rod is positioned and installed on the top end of the two limit blocks, and the top ends of the two shift rods extend through and extend to both sides of the top of the transmission shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] A positioning rod is provided, and a moving block is slidably installed by slotting through the front and rear sides of the transmission shaft, and then a positioning rod is installed at the outer ends of the two moving blocks. At the same time, the outer sides of the two positioning rods are fitly connected to the bottom two sides of the driving gear. When the driving gear needs to be quickly disassembled in the later stage, it is only necessary to move the two moving blocks to drive the two positioning rods to squeeze the driving gear to move its position at the top end of the transmission shaft, so that the auxiliary driving gear can be quickly disassembled and replaced in the later stage.

[0016] Furthermore, mounting rods are provided with slots on the front and rear sides of the top of the transmission shaft, and then a moving block is slidably connected to the outside of the two mounting rods through an extrusion spring. After the driving gear is installed on the outside of the top of the transmission shaft, the driving gear can be squeezed to squeeze the inner ends of the two positioning rods to connect the moving block to squeeze and contract the two extrusion springs to accumulate force. When the driving gear is quickly disassembled and assembled in the later stage, the two extrusion springs can elastically reset the two moving blocks that are squeezed and moved downward by their own elastic force. At this time, the two resetting moving blocks will simultaneously squeeze the driving gear at the top of the transmission shaft through the two positioning rods to perform position extrusion and movement, thereby realizing assisted disassembly of the driving gear, and the operation is more time-saving and labor-saving.

[0017] Furthermore, by using screws to install limit rods on the front and rear sides of the transmission shaft, and then fitting the top ends of the two limit rods to the front and rear sides of the bottom of the driving gear, the installation position of the driving gear can be limited by the two limit rods, thereby avoiding the phenomenon of misalignment of the driving gear after installation, improving the stability of the driving gear and the practicality of the open ultra-high pressure plunger pump.

[0018] A limit block is provided, and the limit blocks with an inclined shape are symmetrically installed by sliding through the slots on both sides of the top of the transmission shaft. When installing the driving gear, you only need to manually squeeze the driving gear on the top of the transmission shaft to press it down. At this time, the driving gear will simultaneously squeeze the two limit blocks to retract and move. When installed in the appropriate position, the two return springs will automatically pop out the two limit blocks into the limit slots opened on both sides of the driving gear through their own elastic force, so that the position of the driving gear after installation can be positioned and fixed, which is more practical.

[0019] Furthermore, when the driving gear needs to be quickly disassembled, assembled, and replaced, it is only necessary to manually move the two levers to drive the two limit blocks to retract and move. At this time, the two limit blocks can be separated from the two limit slots, and then the driving gear can be quickly disassembled, assembled, and replaced, which is faster and more convenient.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] This utility provides the following technical solutions:

[0030] Embodiment 1, in order to solve the problem that when the existing driving gear 2 is disassembled, assembled and replaced, there is no auxiliary disassembly and assembly mechanism to assist the staff to quickly disassemble, assemble and replace the driving gear 2, which will cause the staff to be very time-consuming and labor-intensive when disassembling and assembling the driving gear 2, and the problem of poor practicality, the following is disclosed: a transmission shaft 1 and a driving gear 2, wherein the driving gear 2 passes through the mounting seat on the top outside of the transmission shaft 1, and the diameter of the transmission shaft 1 is smaller than the diameter of the driving gear 2; the top front and rear sides of the transmission shaft 1 are slotted and penetrated by moving blocks 3 that are slidably installed, and the outer end screws of the two moving blocks 3 are installed with positioning rods 4, and the two positioning rods 4 are symmetrically arranged about the transverse center line of the transmission shaft 1, and the tops of the two positioning rods 4 are fitly connected to the bottom front and rear sides of the driving gear 2.

[0031] Mounting rods 5 are slotted on the front and rear sides of the top of the transmission shaft 1, and a moving block 3 is slidably connected to the outer sides of the two mounting rods 5; an extrusion spring 6 is wrapped around the outer sides of the two mounting rods 5, and the two extrusion springs 6 have the same structure, and the top ends of the two extrusion springs 6 are connected to the moving block 3; positioning rods 4 are screwed on the front and rear sides of the top of the transmission shaft 1, and the two positioning rods 4 are symmetrically arranged about the transverse center line of the transmission shaft 1, and the top outer sides of the two positioning rods 4 are fit-connected with the driving gear 2.

[0032] like Figure 1-Figure 5 As shown, when the driving gear 2 is squeezed and lowered to be installed on the outside of the bottom of the transmission shaft 1, the driving gear 2 will simultaneously squeeze the two positioning rods 4 to drive the two moving blocks 3 to be squeezed and lowered on the outside of the two mounting rods 5 through the squeezing springs 6. At this time, the two squeezing springs 6 will be in a stored force state. After the two limit blocks 9 are separated from the limit slots 10, the two squeezing springs 6 will squeeze the two moving blocks 3 through their own elastic force to drive the two positioning rods 4 to drive the driving gear 2 to move up, so that the driving gear 2 can be quickly disassembled, assembled and replaced later. After the driving gear 2 is installed in the appropriate position, the two limit rods 11 will also position the lowered position of the driving gear 2 to prevent deviation, which saves time and effort and is more practical.

[0033] The second embodiment is different from the first embodiment in that the driving gear 2 can be quickly positioned and installed, which saves time and effort.

[0034] The left and right sides of the top of the transmission shaft 1 are slotted through and slidingly installed with limit blocks 9, and the outer sides of the two limit blocks 9 are inclined, and the outer sides of the two limit blocks 9 are engaged and connected to the limit slots 10, and the two limit slots 10 are symmetrically opened on both sides of the inside of the driving gear 2; the slots on both sides of the top of the transmission shaft 1 are provided with return springs 8, and the two return springs 8 have the same structure, and the outer ends of the two return springs 8 are connected to the limit blocks 9; the top ends of the two limit blocks 9 are positioned and installed with shift rods 7, and the top ends of the two shift rods 7 extend through and extend to the top sides of the transmission shaft 1.

[0035] like Figure 1-Figure 7 As shown, when the driving gear 2 needs to be quickly disassembled and replaced, it is only necessary to manually move the two levers 7 to drive the two limit blocks 9 to retract and move, so that the two limit blocks 9 are separated from the two limit slots 10. At this time, the driving gear 2 can be removed from the top of the transmission shaft 1, and then the new driving gear 2 is placed on the top of the transmission shaft 1 and squeezed down. At this time, the driving gear 2 will simultaneously squeeze the two limit blocks 9 to retract and move through the two return springs 8, and then the two return springs 8 will be in a force storage state. After falling to the appropriate position, the two return springs 8 will automatically pop out the two limit blocks 9 into the two limit slots 10 through their own elastic force, so that the position of the installed driving gear 2 can be limited and fixed, avoiding the phenomenon of loosening and falling off of the driving gear 2 during transmission use in the later stage, and better assisting the stable use of the open ultra-high pressure plunger pump.
