Problems solved by technology

[0003] (1) Since the discharge chute and the receiving hopper are open, not only is it easy to spill and leak, but also the moisture in the concrete is easy to evaporate, and the heat preservation effect is also poor
[0004] (2) Since the mixer truck feeds the receiving hopper by self-flowing through the chute, the potential energy of the concrete liquid level in the mixing tank will be completely released during the self-flowing process, which cannot be used to improve the smoothness of feeding
[0005] (3) The mixer truck needs to have a sufficient height to ensure that the concrete flows into the receiving hopper smoothly, resulting in a high height, poor driving safety, and easy overturning; if the mixer truck is low in height, it cannot meet the sufficient and smooth supply of concrete
[0006] (4) The operation on the pouring work surface is passive, and the operator on the pump truck needs to be notified in a certain way. The pouring operation cannot be performed in a timely and free manner, which not only affects the pouring speed, but also requires at least three operators. Usually, the mixer truck 1 person, 1 person for the pump truck, 1 person for the pouring face, and 1 person to take care of the hopper of the pump truck when necessary, which not only affects the efficiency of construction, increases labor costs, but also easily causes spillage and waste of concrete
[0007] (5) The shortage of labor force will become increasingly serious in the future, and the automation, efficiency and informatization of building concrete construction are inevitable. The current feeding methods of mixer trucks and pump trucks cannot meet this requirement at all.
[0008] (6) The existing concrete supply and pouring method, due to the openness of the receiving hopper, has poor thermal insulation and moisture retention. The concrete in the receiving hopper will segregate, delaminate, and slump will decrease due to long-term stirring, and it needs to be pumped by adding water , seriously affecting the improvement of building quality

Embodiment 1

[0027] Such as figure 1 , an integrated duplex concrete supply pouring system, including a mixer truck 100 and a pump truck 200.

[0028] The mixer truck 100 has a mixing bucket 101 that rotates relative to the mixer truck 100 body and a sealing end cover 102 that is installed on the mixer truck 100 body and is positioned at the rear side of the mixing bucket 101. The mixer truck 100 is also provided with a The rotary sealing device between the sealing end cover 102 and the rear end of the mixing bucket 101 is used to prevent concrete from leaking from between the sealing end cover 102 and the mixing bucket 101. The structure of the rotary sealing device can refer to the authorized publication number CN102029940B The rotary sealing mechanism in the Chinese invention patent "concrete mixer truck with rotary sealing of the inlet and outlet of the mixing drum" can also adopt other structural forms; the sealing end cover 102 is provided with a discharge port.

[0029] The mixing ...

Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is that the front end of the mixing drum 101 is driven to a certain height along the axial direction by the tilting drive mechanism arranged on the mixer truck 100 to ensure that the discharge end of the mixing drum 101 has sufficient The height of the liquid level ensures the initial pressure and sufficient supply of concrete feed. In the case of using the tilting drive mechanism, the adjustment of the liquid level by the agitation controller may not be used, or the function of the agitation controller to adjust the liquid level may be retained, and the two are coordinated. The rest of the two embodiments are the same.

[0048] One of the common structures of the tilting drive mechanism: the mixing drum and the end cover are placed on a rotating frame, the rear end of the rotating frame is hinged with the vehicle body or sub-frame, and a hydraulic cylinder is also provided. One end of the hydraulic cylinder It is...

Abstract

The invention discloses an integrated double concrete supplying and pouring system and supplying method. The supplying system comprises a stirring truck and a pump truck, wherein the stirring truck isprovided with a stirring barrel and a sealing end cover, the pump vehicle comprises a closed supplying system, the stirring truck and the pump truck are communicated through a closed supplying pipe and a feeding pipe, so that a communicated concrete fluid with pressure difference is formed, and concrete in a receiving hopper of the pump truck is endowed with lasting supplying pressure. Integratedand concentrated control of the stirring truck and the pump truck is realized by connecting operating systems of the stirring truck and the pump truck. Integrated and automatic operation of the stirring truck and the pump truck is convenient to realize, the concrete pouring construction efficiency is improved, water adding in the pumping position due to concrete water evaporation and slump loss is also avoided, the concrete quality is ensured, overflow leakage of the concrete at the receiving hopper is eradicated, the thermal insulation effect is improved, and the purpose of continuous concrete supply to the pump truck under certain pressure conditions is achieved.

Description

technical field [0001] The invention relates to a concrete pouring supply system, and also relates to a concrete pouring supply method, which is used in the occasion of pumping and pouring concrete in the construction industry. Background technique [0002] At present, pumping and pouring concrete is mainly through the separate operation of the concrete mixer truck and the concrete pump truck to realize the work of feeding the mixer truck and pumping it to the pouring position by the pump truck. The concrete mixer truck feeds the concrete hopper of the pump truck through its discharge chute. This operation needs to be completed by the personnel on the pump truck who observe the mixer truck and the pump truck receiving hopper, the personnel who operate remotely on the pouring work surface, and the operator of the mixer truck. The problem is: [0003] (1) Since the discharge chute and the receiving hopper are open, not only is it easy to spill and leak, but also the moisture...
