Since the hinged set of tubes 2313 are hinged at one end to the barrel 2311 and at the other end to the stationary pump tube 2312, the barrel 2311 is easily deflected and cannot be used to spray the barrel 2311 in a desired direction when concrete grout is being transported in the pour barrel 231. Meanwhile, the barrel 2311 is generally long, and in the process of advancing or retreating the barrel 2311, in order to ensure stable movement of the barrel 2311, a support structure on the template trolley device 3 needs to be attached to realize the gun movement. When the support structure on the formwork trolley device 3 is damaged or the support structure is not provided on the formwork trolley device 3, the stable movement of the gun barrel 2311 cannot be ensured, and further certain trouble can be brought to the operation construction.

In the present embodiment 1, as shown in fig. 6 and 8, the perfusion device 23 of the present embodiment 1 further includes a support frame 233; one end of the supporting bracket 233 is fixed to the traveling unit frame 232, and the other end is connected to the barrel 2311, and the supporting bracket 233 can prevent the barrel 2311 from swinging.

In this embodiment 1, the support 233 can limit the barrel 2311, and can prevent the barrel 2311 from swinging or deflecting as much as possible. So that the gun barrel 2311 can be sprayed in a predetermined direction as much as possible by the support bracket 233 when concrete is transported in the pouring gun barrel 231.

In this embodiment 1, the connection manner between the support 233 and the barrel 2311 is not limited, and the support 233 and the barrel 2311 may be fixedly connected for implementation. Preferably, the support 233 and the barrel 2311 in this embodiment 1 are detachably and fixedly connected; for example, the support frame 233 and the barrel 2311 may be connected by a fastener such as a screw, so that the support frame 233 and the barrel 2311 can be easily attached and detached.

As shown in fig. 8 to 12, in the embodiment 1, a limiting seat 234 is disposed at an end of the supporting frame 233.

Preferably, each set of limit rollers 2342 may include two grooved rollers 23421. Wherein, each spacing roller group 2342 also includes three or four groove type gyro wheels 23421 etc.. Of course, the grooved rollers 23421 in the two limiting roller groups 2342 may be the same or different. For example, in the view shown in fig. 10, the upper limit roller set 2342 is a different model than the slotted roller 23421 in the lower limit roller set 2342. The specific model of the grooved roller 23421 can be selected according to actual conditions.

Further, in order to increase the restriction of the limiting seat 234 on the draft tube 23112, as shown in fig. 11 and 12, the limiting seat 234 in this embodiment 1 further includes a limiting angle plate 2343, and the limiting angle plate 2343 is disposed between at least one set of limiting roller groups 2342 and the draft tube 23112.

For ease of implementation, the limit angle plate member 2343 may select the angle steel.

In order to facilitate an operator to quickly switch a concrete feeding state of the formwork trolley apparatus 3 or a concrete feeding state of the longitudinal pouring apparatus 2 when feeding concrete grout into the formwork trolley apparatus 3 or feeding concrete grout into the longitudinal pouring apparatus 2.

It is thus possible to facilitate an operator to quickly switch the concrete feeding state of the formwork trolley apparatus 3 or the concrete feeding state of the longitudinal pouring apparatus 2 by changing the state of the first switching valve 12 or changing the state of the second switching valve 13.

In embodiment 1, the models of the first on-off valve 12 and the second on-off valve 13 may be selected to be the same or different. For convenience of implementation, the first switch valve 12 and the second switch valve 13 may be selected from solenoid valves, hydraulic valves, and the like.

Further, in the embodiment 1, a pressure gauge 14 is provided on the concrete pump pipe 11. Therefore, when longitudinal pouring operation is carried out, an operator can detect the pouring pressure of concrete slurry through the pressure gauge 14 on the concrete pump pipe 11, and then the operator can conveniently carry out adaptive adjustment on the pouring operation according to different pouring pressures so as to ensure the pouring quality as much as possible.

In addition, the automatic control of the embodiment 1 is also facilitated by providing the pressure gauge 14 on the concrete pump pipe 11. Specifically, a control system may be integrated into the present embodiment 1, and the control system can control the adjustment assembly to move the perfusion barrel 231.

The pressure value detected by a pressure gauge 14 on the concrete pump pipe 11 is named as M, and a threshold value N is preset in the control system. During the filling process, when the pressure value M detected by the pressure gauge 14 is smaller than N, the control system controls the adjusting assembly to keep the original position and continue to fill the position. When the pressure value M detected by the pressure gauge 14 is greater than or equal to N, the control system controls the adjustment assembly to move to the next target position and perform filling on the next target position.

In addition, in embodiment 1, the concrete pump pipe 11 is provided with a flow meter 15. The actual pouring amount of the concrete grout is detected through the flowmeter 15, so that the actual pouring amount of the concrete grout can be compared with the design amount of the concrete grout, and an operator can make judgment and perform adaptability adjustment according to the comparison state of the concrete grout. For example, when the actual amount of concrete grout poured is greater than the designed amount of concrete grout, a grout leak may occur. When the actual pouring amount of the concrete grout is less than the designed amount of the concrete grout, the pouring quality does not reach the standard, and a void or full pouring is caused.

As shown in fig. 14, this embodiment 1 further includes a supporting roller assembly 235, and the supporting roller assembly 235 is located at a side of the walking frame 232 facing the mouth of the barrel 2311, so that during the movement of the barrel 2311, the barrel 2311 can be supported by the supporting roller assembly 235 to ensure the stable movement of the barrel 2311. Thereby enabling the present embodiment 1 to secure stable movement of the gun barrel 2311 without attaching to a support structure on the formwork trolley device 3.

As shown in fig. 14, the supporting roller assembly 235 of the present embodiment 1 includes a mounting frame 2351, a supporting column 2352 and a supporting roller 2353. Wherein, the mounting frame 2351 is fixedly connected with the perfusion frame body. Specifically, the mounting frame 2351 may be selected to be a tripod. The lower end of the support column 2352 is fixedly connected to the mounting frame 2351, and the upper end of the support column 2352 is fixedly connected to the support rollers 2353. Preferably, when the supporting roller assembly 235 is coupled to the traveling block 232, the supporting pole 2352 is vertically arranged such that the installation axis of the supporting roller 2353 is perpendicular to the moving direction of the barrel 2311.
