Description

Technical Field

[0001] The utility model belongs to the technical field of recycled aggregate concrete, and particularly relates to a device for pumping recycled aggregate concrete. Background Art

[0002] Recycled aggregate concrete is a kind of concrete formed by recycling and reprocessing construction waste. Specifically, with the infrastructure development of cities, a large amount of construction waste is generated after large-scale demolition and construction, and a large amount of building materials are needed. After the construction waste is recycled and processed, it can not only be reused as building materials to meet the large demand for building materials in urban construction, but also effectively solve the problem of construction waste pollution. It realizes green environmental protection, recyclable utilization of resources, and at the same time reduces the construction cost of urban construction.

[0003] During the process of recycling construction waste, the waste is sorted, processed and then reprocessed to obtain recycled aggregate concrete. As a casting material, the recycled aggregate concrete is poured into the steel reinforcement cage of the building structure and is used in large quantities in building construction.

[0004] Specifically, the recycled aggregate concrete is pumped by a concrete pump, and the material is discharged from the lower part of a rubber hose made of flexible material. On the one hand, the rubber hose made of flexible material can swing to discharge the concrete to different positions of the steel reinforcement cage. On the other hand, the rubber hose has high operability in discharging materials, and during the discharging process, the discharging position can be corrected in time according to the amount of concrete filled at the discharging position.

[0005] However, in actual work, during the pumping process, the large-diameter rubber hose is filled with concrete, so the weight of the rubber hose is relatively large, and it is relatively laborious for the operator to push it during the process of discharging the concrete by pumping. Moreover, during the construction process, since the rubber hose for discharging materials suspended in the air is located above the steel reinforcement cage, the operator cannot step on the steel reinforcement cage during the construction process, and the equipment for suspending the rubber hose cannot move the rubber hose flexibly, resulting in that it is difficult for the concrete aggregate discharged into the steel reinforcement cage to be evenly filled into the steel reinforcement cage during the discharging process. Summary of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide a device for pumping recycled aggregate concrete.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A device for pumping recycled aggregate concrete includes a rubber hose for pumping concrete, and a distributor is assembled and communicated at the discharging end of the rubber hose. The distributor includes a shell, and the bottom of the shell is of an open structure;

[0009] A plurality of material guiding plates are fixedly connected to the bottom of the shell, and the concrete is discharged from the gaps between the material guiding plates;

[0010] A swing push arm mechanism is assembled and connected to the top of the housing. During the concrete discharging process, the housing is pushed to swing and discharge by the swing push arm mechanism.

[0011] The swing push arm mechanism includes push arms hinged to both sides of the top of the housing.

[0012] The swing push arm mechanism further includes arc-shaped swing tracks fixedly connected to both sides of the bottom of the housing.

[0013] During the swing discharging process, the housing is pushed to swing by the push arms, and during the swinging process of the housing, it is supported by the arc-shaped swing tracks.

[0014] Preferably, a feeding port is provided at the top of the housing, a feeding thick pipe is installed at the feeding port, and the feeding thick pipe is connected to a rubber hose through a flange.

[0015] Preferably, a hinged fixing seat is fixedly connected to the edge part of the top of the housing, a rocker arm plate is hinged to the hinged fixing seat, and the rocker arm plate is hinged to the push arm.

[0016] A hinge opening is provided on the rocker arm plate, and a hinge tongue fixedly connected to the inner end of the push arm is hinged in the hinge opening.

[0017] The hinge tongue is hinged to the hinge opening through a fixing pin shaft.

[0018] Preferably, the push arm includes a horizontal arm part, and a handle arm part bent upward is integrally formed on the horizontal arm part.

[0019] The hinge tongue is fixedly connected to the end position of the horizontal arm part.

[0020] Preferably, columns fixedly connected to the top positions of the arc-shaped swing tracks are respectively fixedly connected to both sides of the bottom of the housing.

[0021] Preferably, a plurality of discharge holes are provided on the outer side wall of the housing, and a plurality of inclined material-dispersing plates are fixedly connected inside the discharge holes.

[0022] During the downward discharge process of the concrete pump material, the inclined material-dispersing plates disperse the concrete slurry.

[0023] Preferably, a shield is fixedly assembled and connected to the rubber hose. During the concrete discharging process, the shield blocks the splashing concrete slurry.

[0024] Preferably, the shield includes a conical part, and a sleeve part is integrally formed at the top of the conical part, and the sleeve part is sleeved on the rubber hose.

[0025] Preferably, a spring hose is communicated with the top of the rubber hose.

[0026] The utility model has the following beneficial effects:

[0027] 1. During the process of pumping and discharging concrete, the concrete is discharged in a dispersed manner. After being loosened by the material spreading plate, the agglomerated materials in the concrete are dispersed, further improving the fluidity of the discharged concrete into the steel reinforcement cage. Especially for high-viscosity concrete, this method can achieve the uniform dispersion of concrete, facilitating the increase of its fluidity.

[0028] 2. During the working process, when the operator pushes the handle arm of the push arm, due to the certain length of the horizontal arm, the spacing is controlled. During the pushing process, the housing - rubber hose swings synchronously. During the swinging process, the discharged concrete slurry is evenly spread in the steel reinforcement cage.

[0029] In this process, by pushing the push arm with the hand, the heavy rubber hose is pushed to swing, which facilitates the discharging of the concrete slurry in a swinging manner, thereby increasing the discharging effect.

[0030] At the same time, since the swinging method is adopted to push the heavy rubber hose to swing and discharge materials, during the working process, this device can solve the technical defect that it is difficult to push the rubber hose during the discharging process of a large-diameter rubber hose.

[0041] Embodiment 1

[0042] As Figures 1-5 shown, a device for pumping recycled aggregate concrete includes a rubber hose 2 for pumping concrete (the same as the existing rubber hose for discharging concrete downward, and the rubber hose 2 is in a vertical state during the process of discharging concrete downward, and it is connected to the discharge pipe of the concrete pump). The discharge end of the rubber hose 2 is assembled and connected with a spreading device (specifically, the top of the housing of the spreading device is provided with a feed inlet, and a feed thick pipe 11 is installed at the feed inlet. The feed thick pipe 11 is connected to the rubber hose 2 through a flange). During the process of pumping and discharging concrete by the spreading device, the concrete is discharged in a dispersed manner.

[0043] Specifically, the spreading device includes a housing 1 (the shape of the housing 1 is a flat cylinder), and the bottom of the housing 1 is an open structure; a plurality of material spreading plates 13 are fixedly connected to the bottom of the housing 1, and the concrete is discharged through the gaps between the material spreading plates 13.

[0044] The shape of the material spreading plate 13 is long strip-shaped, and it is vertically welded at the bottom opening position of the housing 1. During the blanking process, the concrete is dispersed for blanking. After being loosened by the material spreading plate 13, the agglomerated materials in the concrete are dispersed, so as to further improve the fluidity of the concrete discharged into the steel reinforcement cage, especially for the concrete with high viscosity. By using this method, the concrete is dispersed evenly, which is convenient for increasing its fluidity.

[0045] Similarly, a plurality of discharge holes 12 (shaped like long strips) are formed on the outer side wall of the above-mentioned housing 1, and a plurality of inclined material spreading plates 121 are fixedly connected inside the discharge holes 12; during the downward discharge process of the concrete pump material, the inclined material spreading plates 121 disperse the concrete slurry.

[0046] During the process of discharging the concrete through the discharge holes 12, while improving the discharge speed of the concrete, the concrete is dispersed and discharged synchronously in different directions.

[0047] Embodiment 2

[0048] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, when the downward rubber hose 2 is located above the steel reinforcement cage, the operator cannot stand on the steel reinforcement cage structure, such as a cantilevered steel reinforcement cage structure. At this time, in order to achieve uniform discharge of the concrete, a swing push arm mechanism is assembled and connected to the top of the above-mentioned housing 1. During the concrete blanking process, the housing 1 is pushed to swing and blank by the swing push arm mechanism.

[0049] Specifically, the swing push arm mechanism includes push arms 7 hinged at both sides of the top of the housing 1; specifically, a hinged fixing seat 72 is fixedly connected to the top edge of the housing 1, the hinged fixing seat 72 is hinged with a rocker plate 71, and the rocker plate 71 is hinged with the push arm 7; a hinge opening is formed on the rocker plate 71, and an inner end of the push arm 7 is fixedly connected with a hinge tongue 711 hinged in the hinge opening; the hinge tongue 711 is hinged with the hinge opening through a fixing pin shaft.

[0050] The shape of the push arm 7 is:

[0051] The push arm 7 includes a horizontal arm portion, and an upwardly bent handle arm portion is integrally formed on the horizontal arm portion; the hinge tongue is fixedly connected to the end of the horizontal arm portion.

[0052] During the working process, the operator's hand pushes the handle arm portion. Due to the certain length of the horizontal arm portion, the distance is controlled. During the pushing process, the housing 1 - rubber hose 2 swings synchronously. During the swinging process, the discharged concrete slurry is evenly spread in the steel reinforcement cage.

[0053] In this process, the heavy rubber hose 2 is pushed and swung by pushing the push arm 7 with the hand, so as to facilitate the downward discharge of the concrete slurry in a swinging manner, thereby increasing the discharging effect.

[0054] At the same time, since the heavy rubber hose 2 is pushed and swung for discharging in a swinging manner, during the working process, the technical defect that it is laborious to push the rubber hose 2 during the discharging process of the rubber hose 2 with a large diameter is solved by this device.

[0055] The above-mentioned swing push arm 7 mechanism further includes arc-shaped swing tracks 6 fixedly connected to both sides of the bottom of the housing 1; specifically, columns 61 fixedly connected to the top positions of the arc-shaped swing tracks 6 are respectively fixedly connected to both sides of the bottom of the housing 1.

[0056] During the working process, the whole device is supported on the steel reinforcement cage through the arc-shaped swing track 6. During the pushing and swinging process, the arc-shaped swing track 6 makes an arc-shaped swinging motion, and in this way, the force for pushing the rubber hose 2 during the swinging discharging process is further reduced.

[0057] In order to improve the swinging flexibility of the rubber hose 2, in the existing manner, a spring hose 3 is connected to the top of the rubber hose 2, and the spring hose 3 is installed and connected to the discharging pipe of the concrete pump. Since the spring hose 3 can stretch, during the downward discharging process, once the discharging of the rubber hose 2 slows down, the concrete can be conveniently discharged by raising and lowering the rubber hose 2 up and down. For example, when caked materials are blocked and the material discharging is retarded, the discharging can be promoted by shaking up and down.

[0058] Embodiment 3

[0059] As Figures 1-5 shown, on the basis of the structure of Embodiment 2 and on the basis of the structure of Embodiment 1 in this embodiment, a shield 4 is fixedly assembled and connected to the above-mentioned rubber hose 2. During the process of discharging concrete, the shield 4 blocks the splashing concrete slurry. The shield 4 includes a conical part, and a sleeve part 41 is integrally formed at the top of the conical part. The sleeve part 41 is sleeved on the rubber hose 2 (in the same way as the existing method, the sleeve part 41 is locked on the rubber hose 2 by means of a clamp). During the working process, when the operator needs to push the rubber hose 2 by hand to discharge concrete in a swinging manner (such as pouring at a narrow position). At this time, the shield 4 is used to prevent the concrete from splashing onto the operator. Specifically, the discharged concrete is pumped by the concrete pump, so it has a certain impact force. When it hits structures such as steel bars during downward discharging, it is easy to splash.

[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also belong to the protection scope of the present invention.
