Description

Technical Field

[0001] The present application relates to the technical field of grouting equipment, and in particular to a grouting pump for polyurethane slurry. Background Art

[0002] In projects such as strengthening foundations, repairing cracks, and patching leaks, grouting pumps are often used to load polyurethane slurry to grout the points to be repaired.

[0003] Referring to the Chinese patent document with publication number CN204715190U, a high-pressure grouting machine is disclosed, including a tee, a hopper, a power structure and a conveying structure respectively connected to three interfaces of the tee, and the power structure drives the slurry in the hopper to be output from the conveying structure.

[0004] Existing hoppers are usually designed to be higher in order to increase the loading capacity to meet the needs of large-scale grouting. However, in many repair projects, especially small or local repair operations, the amount of raw materials required is not large. In this case, the user still needs to lift the raw material barrel to the top of the hopper to pour the material, making the loading process more laborious. Utility Model Content

[0005] In order to improve the situation where users have difficulty in pouring materials during small repair operations, the present application provides a grouting pump for polyurethane slurry.

[0006] The present application provides a polyurethane slurry grouting pump, which adopts the following technical solution:

[0008] By adopting the above technical solution, the height of the adjusting section is adjusted by extending and retracting the adjusting section, thereby adjusting the hopper capacity and adjusting the height of the feed port at the same time, so that the height of the feed port can be lowered when less raw material is required, making pouring more labor-saving and easy to control the pouring amount.

[0009] Optionally, a support column is provided on the machine body, and the adjustment section has a guide seat that slides up and down on the support column.

[0010] By adopting the above technical solution, the stability and safety of the hopper during the extension and retraction process are improved, and the adjustment process is also made more convenient.

[0011] Optionally, a locking piece is provided on the guide seat, and the locking piece is used to lock the guide seat on the support column.

[0012] By adopting the above technical solution, the locking piece makes it difficult for the bucket to move accidentally due to vibration or external force during the grouting process, thereby improving the stability of the bucket during the grouting process.

[0013] Optionally, the blanking section is expanded in a direction close to the adjusting section.

[0014] By adopting the above technical solution, the expansion of the material discharge section can guide the raw material.

[0015] Optionally, the adjusting section is accordion-shaped.

[0016] By adopting the above technical solution, the extension and retraction of the adjustment section can be conveniently achieved in an accordion-like manner.

[0017] Optionally, one end of the adjusting section away from the blanking section is detachably connected with a sealing cover for covering the adjusting section.

[0018] By adopting the above technical solution, the sealing cover can seal the hopper when the grouting pump is not in use or when transportation is required, so that impurities are not easy to enter the hopper.

[0019] Optionally, the adjusting section is detachably connected to the material discharging section, and a mounting ring is provided at one end of the material discharging section facing the adjusting section, and the sealing cover can be mounted on the mounting ring to cover the material discharging section.

[0021] Optionally, an abutment ring is sleeved on one end of the adjustment section close to the blanking section, a connecting ring is sleeved on the outer periphery of the mounting ring, and the abutment ring and the connecting ring are connected by bolts and nuts.

[0022] By adopting the above technical solution, the bolt and nut connection method between the abutment ring, the mounting ring and the connecting ring makes the disassembly and installation process of the hopper more convenient.

[0023] Optionally, the telescopic portion of the adjusting section is made of high-density polyethylene material.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] 1. The adjusting section can be extended and retracted up and down to adjust its own height, so that the overall height of the hopper can be adjusted, thereby reducing the difficulty of loading and improving the convenience of grouting operations;

[0026] 2. A locking piece is provided on the guide seat, and the guide seat can be locked by the locking piece after the adjustment section is adjusted to an appropriate height, thereby improving the stability of the adjustment section after the height adjustment is completed.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a grouting pump for polyurethane slurry. Figure 1 The grouting pump for polyurethane slurry includes a body 1, a hopper 2, a conveying mechanism 14 and a power mechanism 15. The body 1 is provided with a three-way joint, and the hopper 2, the conveying mechanism 14 and the power mechanism 15 are respectively installed at the interfaces of the three-way joint. The conveying mechanism 14 includes a flexible pipe to convey the slurry, and the power mechanism 15 includes a motor to provide the required rotational power for the grouting pump. The matching method of the hopper 2, the conveying mechanism 14 and the power mechanism 15 is the existing technology and will not be described in detail here.

[0035] Reference Figure 2, wherein the hopper 2 includes a feeding section 21 and an adjusting section 22, both of which are in a cylindrical shape connected up and down. The feeding section 21 is made of hard material and is installed on a three-way joint. The feeding section 21 is in a conical shape with an outer diameter gradually decreasing downward so as to guide the slurry. The adjusting section 22 is made of a flexible material that can be extended and retracted up and down and is installed on the top of the feeding section 21 so that the adjusting section 22 and the feeding section 21 are connected to each other.

[0036] The axes of the material discharge section 21 and the adjusting section 22 extend vertically, and the top of the adjusting section 22 forms the feeding port 3 of the entire hopper 2. The adjusting section 22 adjusts the extension height of the hopper 2 by its own telescoping, thereby adjusting the height of the feeding port 3.

[0037] Reference Figure 1 and Figure 2 In order to improve the stability of the adjustment section 22 when it is extended and retracted, a support column 4 is installed on the machine body 1. The support column 4 has two and is respectively located on opposite sides of the hopper 2. The support column 4 can be fixed to the machine body 1 or can be detachably connected to the machine body 1 by bolts. Guide seats 5 are fixed on the outer walls on opposite sides of the top of the adjustment section 22. The two guide seats 5 correspond to the support columns 4 one by one. The guide seats 5 can slide up and down on the corresponding support columns 4, and the guide seats 5 have locking pieces 6 to fix the guide seats 5 on the support columns 4.

[0038] Reference Figure 2 and Figure 3 Specifically, the support column 4 is in the shape of a vertically extending long strip, the guide seat 5 is in the shape of a block, one side of the guide seat 5 is in contact with one side of the support column 4, and the guide seat 5 is magnetically attracted to the support column 4. The support column 4 is provided with an adjustment slot 11 that passes through two opposite sides of the support column 4 along its own height direction, and the top of the adjustment slot 11 is close to the top of the support column 4 but does not pass through the top of the support column 4, so as to improve the integrity of the support column 4; a locking hole is provided on the guide seat 5, and the adjustment slot 11 is opposite to the locking hole. The locking member 6 includes a bolt and a nut that cooperate with each other, and the bolt rod can pass through the adjustment slot 11 and the locking hole at the same time, and then the nut is screwed into the bolt rod, so that the bolt head and the nut jointly clamp the support column 4 and the guide seat 5, and the support column 4 and the guide seat 5 are positioned by friction.

[0039] When feeding the polyurethane slurry, the adjusting section 22 is first telescopically adjusted according to the required feeding amount, so that when the required slurry amount is small, the feed inlet 3 of the hopper 2 is lower, so that the slurry in the raw material barrel can be poured into the hopper 2 more labor-savingly.

[0040] Reference Figure 2Furthermore, the top of the adjusting section 22 has a mounting portion 12, which is made of hard material and is in a circular ring shape connected to the accordion portion of the adjusting section 22. The mounting portion 12 is matched with a sealing cover 7, which is in a circular cover shape and can be threadedly sleeved on the outer wall of the mounting portion 12 to seal the top of the adjusting section 22, so that dust and impurities outside the adjusting section 22 are not easy to enter the hopper 2.

[0041] Reference Figure 2 and Figure 4 Furthermore, a mounting ring 8 is coaxially fixed to the top of the material-discharging section 21. The mounting ring 8 is annular and made of hard material. The outer diameter of the mounting ring 8 is consistent with the outer diameter of the top of the material-discharging section 21, and the outer diameter of the mounting ring 8 is also consistent with the outer diameter of the mounting portion 12. The outer periphery of the mounting ring 8 has an external thread. The adjusting section 22 is detachably connected to the mounting ring 8. When the adjusting section 22 is removed from the mounting ring 8, the sealing cover 7 can be threadedly sleeved on the mounting ring 8 to close the material-discharging section 21.

[0042] Therefore, when the required amount of polyurethane slurry is less, the adjusting section 22 can be removed from the lower material section 21, and the polyurethane slurry can be directly poured into the lower material section 21 to further reduce the height of the feed port 3 of the hopper 2, making the loading of the polyurethane slurry more labor-saving.

[0043] Reference Figure 4 and Figure 5 , wherein, for the detachable connection between the adjustment section 22 and the mounting ring 8, specifically, an insertion ring 13 is coaxially extended downward from the bottom end of the adjustment section 22, and the outer diameter of the insertion ring 13 is consistent with the inner diameter of the mounting ring 8, so that the insertion ring 13 can be coaxially inserted into the mounting ring 8, so that the adjustment section 22 and the blanking section 21 are connected through the insertion ring 13. And an abutment ring 9 is coaxially fixed to the outer periphery of the bottom end of the adjustment section 22, and the outer diameter of the abutment ring 9 is larger than the outer diameter of the mounting ring 8, and the abutment ring 9 is coaxially fixed to the top surface of the insertion ring 13. When the insertion ring 13 is inserted downward into the mounting ring 8, the lower surface of the abutment ring 9 is driven to abut against the top surface of the mounting ring 8.

[0044] A connecting ring 10 is coaxially fixed on the outer circumference of one end of the mounting ring 8 close to the unloading section 21. The connecting ring 10 is sleeved on the outer wall of the mounting ring 8, and the outer diameter of the connecting ring 10 is consistent with the outer diameter of the abutting ring 9. The abutting ring 9 and the connecting ring 10 are both provided with a number of through holes evenly spaced along their own circumferences, and the through holes are for the rods of the bolts to pass through, and the through holes of the abutting ring 9 correspond to the through holes of the connecting ring 10 one by one, so that the abutting ring 9 and the connecting ring 10 can be connected by the matching of bolts and nuts, so that the abutting ring 9 is pressed against the top surface of the mounting ring 8, the sealing between the abutting ring 9 and the mounting ring 8 is enhanced, and the slurry is not easy to leak from between the abutting ring 9 and the mounting ring 8.

[0045] Furthermore, in other embodiments, the lower surface of the abutment ring 9 may be covered with a sealing rubber layer (not shown in the figure), and the sealing rubber layer is deformed when the abutment ring 9 is pressed against the mounting ring 8 to further improve the sealing effect between the abutment ring 9 and the mounting ring 8.

[0046] In addition, in this embodiment, the accordion material of the adjusting section 22 is made of high-density polyethylene material, which has the characteristics of wear resistance, impact resistance, corrosion resistance, etc., and is not easy to react with polyurethane, thereby improving the stability of the hopper 2.

[0047] The implementation principle of the polyurethane slurry grouting pump of the embodiment of the present application is as follows: when the adjusting section 22 is installed to the feeding section, the feeding port 3 of the hopper 2 is formed at the top of the adjusting section 22, and the height of the feeding port 3 is adjusted by the expansion and contraction of the adjusting section 22. When the guide seat 5 is moved to the desired position on the support column 4, the guide seat 5 and the support column 4 are locked by bolts and nuts to keep the feeding port 3 at the current height, and the bolts and nuts are loosened to readjust the height of the feeding port 3.

[0048] In addition, by removing the adjusting section 22 from the upper section, the feeding port 3 of the hopper 2 can be formed at the top of the lower section 21, so as to further reduce the height of the feeding port 3 to accommodate the charging of less polyurethane slurry.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
