Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring equipment, and more specifically to a foam concrete sky pump truck. Background Art

[0002] Existing concrete pump trucks are mainly used to transport ordinary concrete, that is, concrete containing sand and gravel aggregates. Their working principle is to use high pressure to transport concrete slurry along the pipeline to the pouring site. However, ordinary concrete pump trucks are not suitable for transporting foamed concrete.

[0003] Foamed concrete is a lightweight thermal insulation material with a much lower density than ordinary concrete. It is made of cement, mortar, water and foaming agent. The foaming agent is mechanically foamed through the foaming system of the foaming machine, and the foam is evenly mixed with the cement slurry. The fluidity of foamed concrete is better than that of ordinary concrete, but its strength is also lower. For this reason, a foamed concrete sky pump truck is specially proposed. Summary of the invention

[0004] The utility model aims to solve one of the technical problems in the related technology to a certain extent. To this end, the utility model proposes a foam concrete sky pump truck, which effectively solves the problem of foam concrete transportation by setting a mixing box and equipping a first foam joint and a first cement slurry receiving pipe to achieve flexible connection. Its low density and fluidity enable the cement slurry pressure to transport it to the target area, filling the gap in market demand and promoting the development and application of foam concrete technology.

[0005] The technical solution adopted by the utility model is to provide a foam concrete pump truck, comprising:

[0006] Car body;

[0007] An arm system and a piping system disposed on the vehicle body;

[0008] A mixing box is arranged at the rear of the vehicle body, and the piping system is connected to the sealed cavity inside the mixing box. The mixing box has a first foam joint and a first cement slurry receiving pipe connected to the sealed cavity. The first foam joint is used for externally connecting to the foaming system, and the first cement slurry receiving pipe is used for externally connecting to a pumped cement slurry source.

[0009] With the above structure, the foam concrete pump truck can achieve efficient transportation of foam concrete. Compared with the traditional concrete pump truck, this new type of vehicle has been improved in design to adapt to the characteristics and requirements of foam concrete:

[0010] First, the mixing box is set up to ensure the stability and quality of the foamed concrete during vehicle transportation. The sealed cavity inside the mixing box is connected to the pipeline system, which can effectively prevent the foamed concrete from being disturbed and contaminated by external factors during transportation.

[0011] Secondly, the vehicle is equipped with the first foam joint and the first cement slurry connection pipe, so that the external foaming system and the pumped cement slurry source can be effectively connected to the foam concrete pump truck. This design ensures the flexibility and diversity of the vehicle during use, and can be adjusted and adapted according to specific construction needs.

[0012] Finally, the pumped cement slurry and the foam generated by the foaming system are mixed in the mixing box to form foamed concrete. Since the foamed concrete has a low density and good fluidity, the pressure given by the pumped cement slurry source can transport the foamed concrete a certain distance, that is, the sky pump truck in the utility model can directly transport the foamed concrete to the pouring part through the external pumping mechanism.

[0013] In summary, the launch of this foam concrete pump truck fills the gap in the market and provides an efficient and reliable solution for the delivery of foam concrete. In the building and construction industry, this will be an innovation of great significance and is expected to promote the further development and application of foam concrete technology.

[0014] According to one embodiment of the utility model, the vehicle body includes a chassis, a turntable arranged on the chassis, and a plurality of legs; the legs are usually adjustable, so that the operator can adjust the support angle and height according to the actual working environment to ensure that the vehicle can remain stable in various terrains and working conditions. The application of this technology not only improves the efficiency of the use of the sky pump truck, but also increases work safety, bringing greater convenience and benefits to the construction and transportation industries.

[0015] According to one embodiment of the utility model, the first foam joint is connected to a bubble outlet pipe, the bubble outlet pipe is horizontally arranged in the sealed cavity, and the outer periphery of the bubble outlet pipe has a bubble outlet hole connected to the sealed cavity; the foaming system will provide a certain air pressure to generate foam, and this air pressure is greater than the delivery pressure of the cement slurry source, which effectively avoids the cement slurry from clogging or backflowing the bubble outlet hole.

[0016] According to one embodiment of the utility model, the pipeline system includes an output pipe and a connecting pipe, the output pipe is located at one end of the arm system away from the vehicle body, one end of the connecting pipe is connected to the mixing box, and the other end is connected to the output pipe; the foamed concrete formed by mixing cement slurry and foam in the mixing box is transported to the casting site through the connecting pipe and the output pipe in sequence.

[0017] According to an embodiment of the utility model, the connecting pipe passes through the rotating shaft of the turntable on the vehicle body and is connected to the output pipe; because the arm system of the sky pump truck needs to adjust the position at multiple angles, the arm system is installed on the vehicle body through the turntable, so that the arm system can rotate relative to the turntable. In order to prevent the pipe system of the arm system from getting entangled or corners due to bending during the rotation process, which affects the transportation of foam concrete, the connecting pipe is set at the rotating shaft position of the turntable.

[0018] According to one embodiment of the utility model, a first pumping mechanism is provided in the pipeline between the connecting pipe and the mixing box; since the externally pumped cement slurry has a certain pressure, the first pumping mechanism is used to increase it, so that the foam concrete overcomes the pipeline resistance and is transported to the pouring site.

[0019] According to one embodiment of the utility model, the pipeline system includes a spare pipe, one end of which is connected to the mixing box; since the pipeline system is prone to blockage during the actual construction process, in order not to affect the progress, a spare pipe is also provided as a redundant design, and when the connecting pipe is blocked, the spare pipe is connected to the output pipe through an external pipe.

[0020] According to an embodiment of the utility model, a second pumping mechanism is provided in the pipeline between the spare pipe and the mixing box; similarly, the second pumping mechanism is designed as a redundant mechanism, and when the connecting pipe is blocked, the second pumping mechanism can pressurize the spare pipe.

[0021] According to an embodiment of the utility model, the mixing box further comprises a second cement slurry receiving pipe communicating with the sealing cavity.

[0022] According to an embodiment of the present invention, the mixing box further comprises a second foam joint communicating with the sealing cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example

[0040] like Figure 1-10 As shown, in this embodiment, a foam concrete pump truck is disclosed, comprising:

[0041] Car body 1;

[0042] An arm system 2 and a pipe system 3 arranged on the vehicle body 1;

[0043] A mixing box 4 is arranged at the rear of the vehicle body 1, and the piping system 3 is connected to the sealed cavity 41 inside the mixing box 4. The mixing box 4 has a first foam joint 5 and a first cement slurry receiving pipe 6 connected to the sealed cavity 41. The first foam joint 5 is used for externally connecting to the foaming system, and the first cement slurry receiving pipe 6 is used for externally connecting to a pumped cement slurry source.

[0044] Furthermore, combined with Figure 1-2 As shown, the boom system 2 is mainly composed of a foldable and unfoldable planar four-bar mechanism that is articulated by multiple boom sections, connecting rods, cylinders, and connecting parts. According to the different rotation directions and sequences between the booms, the boom has a variety of folding forms, such as: R type, Z type (or M type), comprehensive type, etc.

[0045] Furthermore, combined with Figure 1-4 As shown, in this embodiment, the chassis 11 of the vehicle body 1 is provided with four legs 13, which can be unfolded or folded relative to the vehicle body 1, and each leg 13 has the function of lifting up and down. During construction, since the area covered by the sky pump truck is large, the arm system 2 extends a long distance. The four legs 13 are unfolded in an X shape to expand the coverage area of ​​the vehicle body 1 on the ground, ensure its bearing capacity and the anti-rollover ability of the whole vehicle, and ensure the safety and stability of the pump truck during operation.

[0046] Furthermore, combined with Figure 2 As shown, in this embodiment, the pipeline system 3 is laid on the boom system 2, and the pipeline system 3 is unfolded or folded synchronously with the boom system 2. Among them, a receiving hopper is set at the rear of the traditional sky pump truck, and the receiving hopper is used to receive the concrete containing sand and gravel aggregate output by the concrete mixer truck. In this embodiment, the receiving hopper is replaced by a mixing box 4, and the mixing box 4 has a sealed chamber 41 inside to prevent the foaming system from generating foam or the cement slurry or foamed concrete from leaking, causing pressure loss.

[0047] Furthermore, during construction, it is only necessary to drive the sky pump truck to a predetermined position, unfold the four legs 13 and prop up the legs 13, so that the vehicle body 1 is out of contact with the ground. Then, the arm system 2 is unfolded, and the pipeline system 3 is unfolded synchronously with the arm system 2 until the output pipe 31 of the pipeline system 3 is aligned with the part to be poured. Then, the first foam joint 5 is externally connected to the foaming system, and the first cement slurry receiving pipe 6 is externally connected to the pumped cement slurry source. The cement slurry and the foam generated by the foaming system are mixed in the mixing box 4 to generate foamed concrete. The foamed concrete is transported to the pouring part through the pipeline system 3.

[0048] Specifically, combined Figure 4-5As shown, the vehicle body 1 includes a chassis 11, a turntable 12 arranged on the chassis 11, and four legs 13; the legs 13 are usually adjustable, so that the operator can adjust the support angle and height according to the actual working environment to ensure that the vehicle can remain stable in various terrains and working conditions. The application of this technology not only improves the efficiency of the sky pump truck, but also increases work safety, bringing greater convenience and benefits to the construction and transportation industries.

[0049] Specifically, combined Fig. 9 As shown, in this embodiment, the first foam joint 5 is arranged on one side of the mixing box 4, which causes the foam distributed on this side to be denser than the foam on the other side, which easily leads to uneven distribution of pore sizes in the poured foam concrete.

[0050] In order to solve the problem of uneven pore distribution, combined with Fig.10 As shown, in another embodiment, the first foam joint 5 is connected to a bubble outlet pipe 42 , the bubble outlet pipe 42 is horizontally arranged in the sealing cavity 41 , and the outer periphery of the bubble outlet pipe 42 has bubble outlet holes connected to the sealing cavity 41 .

[0051] Furthermore, the bubble outlet pipe 42 is located in the mixing box 4 and connects the left and right sides of the mixing box 4. The foaming system provides a certain air pressure to generate foam. The foam passes through the bubble outlet pipe 42 to cover the interior of the mixing box 4, thereby improving the uniformity of the pore distribution of the foamed concrete.

[0052] Specifically, combined Figure 7-8 As shown in the figure, the material delivery pipeline of the pump truck is shown. The material delivery pipeline of the pump truck includes a pipeline system 3, a first foam joint 5, a first cement slurry receiving pipe 6, a second cement slurry receiving pipe 7, a first pumping mechanism 8, a second pumping mechanism 9 and a second foam joint 10. The pipeline system 3 includes an output pipe 31 and a connecting pipe 32. The output pipe 31 is located at one end of the arm system 2 away from the vehicle body 1. One end of the connecting pipe 32 is connected to the mixing box 4, and the other end is connected to the output pipe 31. The connecting pipe 32 passes through the rotating shaft of the turntable 12 on the vehicle body 1 and is connected to the output pipe 31. The pipeline between the connecting pipe 32 and the mixing box 4 is provided with a first pumping mechanism 8. The pipeline system 3 includes a spare pipe 33. One end of the spare pipe 33 is connected to the mixing box 4. The pipeline between the spare pipe 33 and the mixing box 4 is provided with a second pumping mechanism 9. The mixing box 4 also has a second cement slurry receiving pipe 7 and a second foam joint 10 connected to the sealing cavity 41.

[0053] Since the pipeline system 3 is prone to blockage during the actual construction process, in order not to affect the process, a spare pipe 33 is also provided as a redundant design. When the connecting pipe 32 is blocked, the spare pipe 33 is connected to the output pipe 31 through an external pipe. Similarly, the second pumping mechanism 9 is a redundant design. When the connecting pipe 32 is blocked, the second pumping mechanism 9 can pressurize the spare pipe 33.
