Description
Technical Field
[0001] The invention relates to the technical field of construction site building, in particular to a shock absorbing device for a pumping pipe of a foam concrete foaming machine. Background Art
[0002] Foamed concrete is a lightweight, porous building material made from a mixture of cement-based materials, a foaming agent, and admixtures. Its uniformly distributed closed-cell structure imparts its lightweight, high thermal insulation, sound absorption, and fire retardancy. A concrete foaming machine is a highly efficient and convenient construction equipment. It thoroughly mixes air with concrete slurry to produce a large amount of uniform, fine foam, thereby producing lightweight, porous foamed concrete. Pumping pipes are crucial piping equipment for conveying concrete in construction. Made of high-strength, wear-resistant materials, they can withstand the high pressure and friction experienced during the concrete pumping process. Well-designed pumping pipes with tight connections ensure leak-free and blockage-free concrete delivery, ensuring continuous and efficient construction.
[0003] Most of the existing foam concrete machine pumping pipes have weak vibration reduction performance and a single method. They mainly rely on slight deformation of the pipe body and a small amount of rubber pads or simple springs at the connection to reduce vibration. At the same time, the pumping pipes are mostly fixed with rigid connections, which makes it difficult for these basic components to fully absorb and disperse the vibration energy generated during the pumping process. Therefore, when conveying concrete, vibration is easily transmitted to the surrounding structure through the pumping pipe, which not only affects the stability of the construction environment, but may also have an adverse effect on construction quality and safety. Therefore, a foam concrete machine pumping pipe vibration reduction device is proposed. Summary of the Invention

[0007] The above technical solution further includes:
[0008] The discharge pipe is movably connected to the connecting steel pipe, and the end of the connecting steel pipe away from the pumping pipe is fixedly connected to a rubber pad. The rubber pad is movably connected to the discharge pipe, and the end of the connecting steel pipe away from the discharge pipe is fixedly connected to the corrugated rubber tube.

The interior of the connecting steel pipe is fixedly connected to a support rod, and the outer side of the support rod is fixedly connected to a first cylindrical shell.

[0010] The first cylindrical shell is fixedly connected to the first spring, the first spring is fixedly connected to the buffer conical block, and the buffer conical block is movably connected to the first cylindrical shell.

A movable rod is movably connected to the outer side of the cylindrical ring rubber block.

A convex groove is provided on the side of the second support plate, and a convex block is fixedly connected to the bottom of the fixing clamp, and the convex block is slidably connected to the convex groove. The fixing clamp is movably connected to the pumping pipe, and the forward and reverse rotation of the third threaded rod causes the two fixing clamps to move relative to each other on the second support plate.
[0017] The present invention has the following beneficial effects:
[0018] 1. In the present invention, the impact force during the transportation of foam concrete and the vibration generated by the foaming machine are effectively absorbed and dispersed by the buffer cone block, the first spring and the corrugated rubber tube in the shock-absorbing assembly.

[0019] 2. In the present invention, the design of the fixing clamp in the shock-absorbing assembly in conjunction with the second spring and the third spring effectively reduces the vibration of the pumping pipe when conveying foam concrete.

DETAILED DESCRIPTION
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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] Example 1
[0030] like Figure 1-Figure 7 As shown, the present invention proposes a foam concrete foaming machine pumping pipe shock absorption device, including a bottom plate 1, a foaming machine 2 is fixedly connected to the upper part of the bottom plate 1, a discharge pipe 3 is fixedly connected to the outer side of the foaming machine 2, a pumping pipe 6 is fixedly connected to the outer side of the foaming machine 2, a shock absorbing component is provided on the outer side of the foaming machine 2, and the shock absorbing component includes a buffer cone block 12 and a first spring 14 movably connected to the outer side of the foaming machine 2, and a corrugated rubber tube 5 fixedly connected to the outer side of the foaming machine 2. The foaming machine 2 transports foam concrete through the discharge pipe 3, and the transported foam concrete impacts the buffer cone block 12. The impacted buffer cone block 12 squeezes the first spring 14 to weaken the impact force of the transported foam concrete. The delivery pipe 6 is connected through the corrugated rubber tube 5, so that the impact generated by the foam concrete passing through the corrugated rubber tube 5 and the vibration generated by the foaming machine 2 are once again buffered and shock-absorbed, thereby reducing the vibration of the pumping pipe 6. A shock-absorbing assembly is provided on the outside of the foaming machine 2, and the shock-absorbing assembly includes a fixing clamp 7 and a second spring 25 symmetrically and movably connected on the outside of the foaming machine 2, and a third spring 26 fixedly connected to the outside of the foaming machine 2. The fixing clamp 7 fixes the pumping pipe 6. When the foam concrete is transmitted in the pumping pipe 6, the vibration generated is shock-absorbed by the second springs 25 on both sides and the third spring 26 at the bottom, so that the vibration effect of the pumping pipe 6 is weakened, and the second spring 25 and the third spring 26 reduce the vibration generated by the foaming machine 2.
[0031] The discharge pipe 3 is movably connected to the connecting steel pipe 4, and the end of the connecting steel pipe 4 away from the pumping pipe 6 is fixedly connected to a rubber pad 8. The rubber pad 8 is movably connected to the discharge pipe 3, and the end of the connecting steel pipe 4 away from the discharge pipe 3 is fixedly connected to the corrugated rubber tube 5. The rubber pad 8 is connected between the connecting steel pipe 4 and the discharge pipe 3 to prevent side leakage of foam concrete.
[0032] The corrugated rubber tube 5 is fixedly connected to the pumping pipe 6 at one end away from the connecting steel pipe 4. A support rod 11 is fixedly connected to the inside of the connecting steel pipe 4. A first cylindrical shell 13 is fixedly connected to the outside of the support rod 11. The first cylindrical shell 13 supports the buffer conical block 12 and protects the first spring 14.
[0033] The first cylindrical shell 13 is fixedly connected to the first spring 14, the first spring 14 is fixedly connected to the buffer conical block 12, and the buffer conical block 12 is movably connected to the first cylindrical shell 13. The foam concrete impacts the buffer conical block 12 through the connecting steel pipe 4, and the impacted buffer conical block 12 squeezes the first spring 14 and rebounds.
[0034] In this embodiment, when the device is used, the pumping pipe 6 is connected to the discharge pipe 3 through the connecting steel pipe 4, and the rubber pad 8 is connected between the connecting steel pipe 4 and the discharge pipe 3 to prevent the foam concrete from leaking sideways. When the foaming machine 2 is started, the foam concrete is transmitted to the inside of the pumping pipe 6 through the discharge pipe 3, so that the pumping pipe 6 is poured. At this time, the foam concrete passes through the connecting steel pipe 4 and collides with the buffer cone block 12. The impacted buffer cone block 12 squeezes the first spring 14 and rebounds, so that the impact force of the foam concrete contacts the buffer cone block 12 to weaken it. When the foam concrete passes through the corrugated rubber tube 5, the special shape and material of the corrugated rubber tube 5 can buffer the vibration generated by the passing foam concrete and reduce the amplitude of the vibration. The discharge pipe 3 and the pumping pipe 6 are connected by the corrugated rubber tube 5, which further buffers the vibration caused by the start-up of the foaming machine 2 and reduces the impact on the pumping pipe 6.
[0035] Example 2
[0036] like Figure 1-Figure 7 As shown, based on the first embodiment, the upper part of the base plate 1 is rotatably connected to the second threaded rod 18, the side of the base plate 1 close to the second threaded rod 18 is fixedly connected to the first limiting rod 19, and the side of the base plate 1 close to the first limiting rod 19 is rotatably connected to the first threaded rod 16, and the rotation of the first threaded rod 16 drives the second threaded rod 18 to rotate through the gear 17.
[0037] The outer side of the second threaded rod 18 is fixedly connected to a gear 17, which is meshed with the first threaded rod 16. The second threaded rod 18 is threadedly connected to the first support plate 9. The outer side of the first threaded rod 16 is fixedly connected to a handle 15. The forward and reverse rotation of the second threaded rod 18 causes the first support plate 9 to drive the fixing clamp 7 to move up and down on the first limit rod 19.
[0038] The first support plate 9 is slidably connected to the first limiting rod 19. A cylindrical ring rubber block 28 is fixedly connected to the outer side of the first support plate 9. A movable rod 27 is movably connected to the outer side of the cylindrical ring rubber block 28. The first limiting rod 19 restricts the first support plate 9, allowing the first support plate 9 to slide on the first limiting rod 19.
[0039] The end of the movable rod 27 away from the first support plate 9 is fixedly connected to the second support plate 10, the side of the first support plate 9 close to the second support plate 10 is fixedly connected to the third spring 26, and the end of the third spring 26 away from the first support plate 9 is fixedly connected to the second support plate 10. The third spring 26 reduces shock to the vibrating pumping pipe 6.
[0040] The outer side of the second support plate 10 is symmetrically and movably connected with connecting rods 24. The two connecting rods 24 are movably connected with the second cylindrical shell 23 at one end away from the second support plate 10. The second cylindrical shell 23 is movably connected to the first support plate 9. The second cylindrical shell 23 is fixedly connected to the second spring 25. The second spring 25 is fixedly connected to the connecting rod 24. The second spring 25 and the third spring 26 can also reduce the vibration generated by the foaming machine 2.
[0041] A second limiting rod 20 is fixedly connected to the outer side of the second support plate 10, and a third threaded rod 21 is rotatably connected to the outer side of the second support plate 10. The third threaded rod 21 is threadedly connected to the fixing clamp 7, and the fixing clamp 7 is slidingly connected to the second limiting rod 20. A convex groove 22 is provided on the side of the second support plate 10, and a convex block 29 is fixedly connected to the bottom of the fixing clamp 7. The convex block 29 is slidingly connected to the convex groove 22, and the fixing clamp 7 is movably connected to the pumping pipe 6. The forward and reverse rotation of the third threaded rod 21 causes the two fixing clamps 7 to move relative to each other on the second support plate 10.
[0042] In this embodiment, as described in the upper step, the pumping pipe 6 is connected to the discharge pipe 3, and the hand rotates the handle 15. The rotation of the handle 15 drives the first threaded rod 16 to rotate, and the rotation of the first threaded rod 16 drives the second threaded rod 18 to rotate through the gear 17. The positive and negative rotation of the second threaded rod 18 causes the first support plate 9 to drive the fixing fixture 7 to move up and down on the first limit rod 19, so that the fixing fixture 7 is adjusted to a suitable position according to the pumping pipe 6. At this time, by rotating the third threaded rod 21, the positive and negative rotation of the third threaded rod 21 causes the two fixing fixtures 7 to move relative to each other on the second support plate 10. The two fixing clamps 7 move toward the pumping pipe 6, so that the fixing clamps 7 fix the pumping pipe 6. When foam concrete is transmitted in the pumping pipe 6, the vibration generated by the foam concrete causes the pumping pipe 6 to pull the second spring 25 through the connecting rod 24 and squeeze the third spring 26 through the second support plate 10. In this way, the second spring 25 and the third spring 26 dampen the vibration of the pumping pipe 6, and the second spring 25 and the third spring 26 can also dampen the vibration generated by the foaming machine 2, thereby reducing the vibration generated by the pumping pipe 6. The material of the pumping pipe 6 is also a shock-absorbing material, which makes the shock-absorbing effect better.
[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
