Abstract
Description
Technical Field
[0001] This utility model relates to the field of plunger pump technology, specifically to the cylinder body of a plunger pump for ultra-high pressure civilian mechanical equipment. Background Technology
[0002] Ultra-high pressure plunger pumps are widely used in civil cleaning, high-pressure water injection in buildings, and industrial spraying. Their cylinders (front and rear housings), as core pressure-bearing components, are subjected to combined loads such as high-pressure fluid impact, mechanical vibration, and temperature cycling over long periods, making them prone to minor damage such as planar warping and edge deformation. However, existing technologies have significant limitations in monitoring and preventing cylinder deformation. Current strategies are essentially "repair after failure": repairs are only carried out after cylinder deformation causes visible faults such as leakage, abnormal vibration, and pressure drops. This not only results in long repair cycles (requiring replacement of seals, cylinder repair, and even replacement of core components like the crankshaft) but also leads to production interruptions due to sudden shutdowns (such as high-pressure cleaning line shutdowns or building water injection stoppages), causing additional economic losses.
[0003] Therefore, this utility model provides a piston pump cylinder body for ultra-high pressure civilian mechanical equipment. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a plunger pump cylinder body for ultra-high pressure civil mechanical equipment to solve the above problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a plunger pump cylinder body for ultra-high pressure civil machinery equipment, comprising a plunger pump housing assembly, the plunger pump housing assembly comprising a front housing and a rear housing, a positioning plate installed at one end of the front housing, a front positioning ring and a rear positioning ring fitted on the front housing and the rear housing, a sliding rod slidably connected to the inner wall of the front positioning ring and the rear positioning ring, a support frame installed between the two sliding rods, a transverse rod slidably connected to the inner wall of the support frame, a slider slidably connected to the inner wall of the transverse rod, a threaded rod threadedly connected to the slider, a vertical rod slidably connected to the threaded rod, a support head installed at one end of the vertical rod, a spring A fitted on the outer wall of the vertical rod, a docking rod corresponding to the positioning plate slidably connected to the sliding rod, four equidistantly distributed docking holes on the outer wall of the positioning plate, and one end of the docking rod engaging with the docking hole.
[0006] Preferably, the positioning plate has a slot, and a locking block is engaged with the inner wall of the slot. A side bracket is installed at one end of the locking block, and one side of the side bracket is connected to one end of the front positioning ring.

An adjusting rod is installed at the top of the connecting plate, and a fixing plate is threaded onto the adjusting rod. One side of the fixing plate is connected to one end of the rear positioning ring.
[0008] Preferably, the support block has a support groove that matches the connecting plate, and the bottom of the adjusting rod is rotatably connected to the connecting plate.
[0009] Preferably, a protruding plate is installed on the outer wall of the docking rod, and a spring B is sleeved on the outer wall of the docking rod. Beneficial effects

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-3 As shown, the cylinder body of the ultra-high pressure civil mechanical equipment plunger pump includes a plunger pump housing assembly 1. The plunger pump housing assembly 1 includes a front housing 11 and a rear housing 12. A positioning plate 2 is installed at one end of the front housing 11. A front positioning ring 22 and a rear positioning ring 23 are fitted on the front housing 11 and the rear housing 12.
[0015] Among them, the inner walls of the front positioning ring 22 and the rear positioning ring 23 are slidably connected to the slide rods 4, and the support frame 41 is installed between the two slide rods 4. The inner wall of the support frame 41 is slidably connected to the transverse rod 42, the inner wall of the transverse rod 42 is slidably connected to the slider 43, the slider 43 is threadedly connected to the threaded rod 44, the threaded rod 45 is slidably connected to the vertical rod 45, and a support head 46 is installed at one end of the vertical rod 45.
[0016] It should be noted that, in this embodiment, the slider 43 slides horizontally on the inner wall of the transverse rod 42, and the transverse rod 42 slides horizontally on the inner wall of the support frame 41.
[0017] A spring A451 is fitted on the outer wall of the upright 45. A docking rod 47 corresponding to the positioning plate 2 is slidably connected on the sliding rod 4. Four docking holes 26 are equidistantly distributed on the outer wall of the positioning plate 2. One end of the docking rod 47 is engaged with the docking hole 26.
[0018] It should be noted that, in this embodiment, one end of the spring A451 is connected to the upright 45, and the other end is connected to the bottom end of the threaded rod 44.
[0019] Specifically, the plunger pump housing assembly 1 is divided into two parts: a front housing 11 and a rear housing 12. During use, due to its high-pressure operation, damage to the housing assembly 1 can disrupt the normal fit of its internal components, leading to significant abnormalities in pump operation and increasing the risk of breakage and damage. To address this, after the plunger pump housing assembly 1 is activated, the front positioning ring 22 and the rear positioning ring 23 are respectively fitted onto the outer sides of the front housing 11 and the rear housing 12. The front and rear positioning rings 22 and 23 are kept at a uniform level. The slide rod 4 slides against the inner walls of the front and rear positioning rings 22 and 23, allowing the support frame 41 connected between the slide rods 4 to mount the transverse rod 42. The transverse rod 42 can then slide along its inner wall. The slider 43 is adjusted by sliding, so that its position can be adjusted in conjunction with the sliding adjustment of the transverse rod 42, so that the slider 43 can correspond to various positions on the outer wall of the plunger pump housing assembly 1, and the slide rod 4 can slide to correspond to various wall surfaces of the plunger pump housing assembly 1. After the slider 43 is aligned with various positions on the outer wall of the plunger pump housing assembly 1, the threaded rod 44 connected to the slider 43 can rotate, so that the vertical rod 45 slidably connected to the threaded rod 44 can be supported by the spring A451, so that the support head 46 installed at one end of the vertical rod 45 can be supported on the outer wall of the plunger pump housing assembly 1. At this time, when the plunger pump housing assembly 1 is not started, the support head 46 is supported on the outer wall of the plunger pump housing assembly 1, and the vertical rod 45 slides on the threaded rod 44. On rod 44, one end of the upright rod 45 is kept at a fixed length on one end of the threaded rod 44. By rotating the slide rod 4, the length of the upright rod 45 protruding from the threaded rod 44 on each side is recorded. After recording, the front positioning ring 22 and the rear positioning ring 23 can be separated. After the front positioning ring 22 and the rear positioning ring 23 are separated, the plunger pump housing assembly 1 can be used. After the plunger pump housing assembly 1 is used, the front positioning ring 22 and the rear positioning ring 23 can be reinstalled, and the positions on each of the four sides of the plunger pump housing assembly 1 can be repeatedly tested. At this time, by comparing the length of the upright rod 45 protruding from the threaded rod 44 on the front and rear ends, the difference in length between the two protrusions of the upright rod 45 from the threaded rod 44 can be used to... The analysis detects whether the four sides of the plunger pump housing assembly 1 are deformed, thus facilitating the monitoring of the normal operation of the outer wall of the plunger pump housing assembly 1. This allows for safety monitoring after each use before the next use, preventing overall or partial deformation of the plunger pump housing assembly 1, which could lead to gear oil or hydraulic oil leakage, polluting the environment and causing insufficient lubrication of the internal crankshaft and connecting rods, accelerating wear and damage. When the slide rod 4 slides on the inner wall of the front positioning ring 22 and the rear positioning ring 23, it can connect to the four docking holes 26 on the positioning plate 2 through the docking rod 47 slidably connected to the slide rod 4. This allows the slide rod 4 to maintain a flush position with each surface, thereby ensuring the accuracy of deformation detection on each surface.
[0020] In one embodiment of this utility model, such as Figures 1-3 As shown, a slot 24 is provided on the positioning plate 2, and a block 25 is engaged with the inner wall of the slot 24. A side bracket 21 is installed at one end of the block 25, and one side of the side bracket 21 is connected to one end of the front positioning ring 22.
[0021] It should be noted that, in this embodiment, the positioning plate 2 installed on the front housing 11 corresponds to the center of the front positioning ring 22, and the slot 24 is slidably connected to the inner wall of the block 25.
[0022] Specifically, by fixing the side frame 21 to one end of the front positioning ring 22, the locking block 25 installed on the side frame 21 can be inserted and positioned into the inner wall of the slot 24 opened on the positioning plate 2, so that the front positioning ring 22 is positioned and sleeved on the front housing 11, and the height of the front positioning ring 22 is supported and limited.
[0023] In one embodiment of this utility model, such as Figures 1-3 As shown, the rear housing 12 is equipped with symmetrical support blocks 3, which are snapped onto the connecting plate 32. The top of the connecting plate 32 is equipped with an adjusting rod 321, and a fixing plate 33 is threaded onto the adjusting rod 321. One side of the fixing plate 33 is connected to one end of the rear positioning ring 23.
[0024] It should be noted that, in this embodiment, the height of the connecting plate 32 is adjusted by rotating the adjusting rod 321, thereby controlling the connection between the connecting plate 32 and the support block 3.
[0025] Specifically, the rear positioning ring 23 rotates via the adjusting rod 321, causing the connecting plate 32 to engage with the support block 3, thereby limiting the height and position of the rear positioning ring 23, thus keeping the front positioning ring 22 and the rear positioning ring 23 horizontally aligned, and allowing the slide rod 4 and the support frame 41 to slide around the plunger pump housing assembly 1.
[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, the support block 3 has a support groove 31 that matches the connecting plate 32, and the bottom of the adjusting rod 321 is rotatably connected to the connecting plate 32.
[0027] It should be noted that the support groove 31 and the connecting plate 32 described in this embodiment are slidably connected.
[0028] Specifically, the adjusting rod 321 is rotatably connected to the top of the connecting plate 32, so that as the adjusting rod 321 rotates, the connecting plate 32 can continuously slide into the inner wall of the support groove 31, thereby connecting the fixing plate 33, the adjusting rod 321 and the support block 3, and limiting the position of the rear positioning ring 23.
[0029] In one embodiment of this utility model, such as Figures 1-3 As shown, a protruding plate 471 is installed on the outer wall of the connecting rod 47, and a spring B472 is sleeved on the outer wall of the connecting rod 47.
[0030] It should be noted that, in this embodiment, one end of the spring B472 is connected to the bottom end of the slide bar 4, and the other end is connected to the protruding plate 471.
[0031] Specifically, the spring B472 supports the convex plate 471, causing the convex plate 471 to push the docking rod 47 to engage and support it on the inner wall of the docking hole 26. This allows the slide rod 4 to be positioned on the surface corresponding to the plunger pump housing assembly 1, thus avoiding the need for inspection of the plunger pump housing assembly 1.
[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0033] Working principle: Connect the side frame 21 to the front positioning ring 22. The locking block 25 is inserted into the slot 24 on the positioning plate 2, so that the front positioning ring 22 is horizontally fitted and axially limited. Rotate the adjusting rod 321 to drive the connecting plate 32 to slide into the support groove 31. Adjust the height of the rear positioning ring 23 and fix it with the fixing plate 33 to ensure that the front positioning ring 22 and the rear positioning ring 23 are coaxially aligned. The sliding seat slide rod 4 slides along the inner wall of the front positioning ring 22 and the rear positioning ring 23, forming a "ring-shaped" structure through the connecting frame support frame 41, covering the four sides of the cylinder body. Adjust the position of the transverse rod 42 in the support frame 41. Rotate the adjusting slider 43 so that the threaded rod 44 drives the support head 46 to lightly touch the outer wall of the cylinder body. Mark the initial extension length by recording the relative position of the threaded rod 44 and the slide rod 4 with a scale or marker. The sliding docking rod 47 is inserted into the docking hole 26 on the positioning plate 2. The spring B472 pushes up the protrusion plate 471 and locks the angle of the slide rod 4 to ensure that the detection head is aligned with the cylinder body surface.
