[0034] Working principle: When a small hydraulic slipform concrete casting truck is needed, first, the hydraulic motor 30 (rear axle) changes speed through the reducer 27 (rear axle) and transmits power to the rear axle 35 of the vehicle, thereby driving the rear left drive wheel 31 and the rear right drive wheel 25. At the same time, the hydraulic motor 30 (front axle) also drives the front left drive wheel 2 and the front right drive wheel 24 of the front axle 60 of the vehicle. The hydraulic control system 28 can control the front and rear four-wheel travel of the walking mechanism 8 and drive the movement of the vehicle body 1 and the slipform 4. The slipform 4 includes a longitudinal slipform 5, a transverse formwork 17 and a wing plate 23, which enhances its bearing capacity and bending resistance through a plate reinforcement structure. The transmission of the hydraulic motor 30 (turntable) changes speed through the reducer 27 (turntable) and is converted into upright rotation in the gear box of the turntable 11, driving the support shaft 40, the support rod 41, the rotating cylinder 9 and the vibrator 6 to rotate synchronously. The oil cylinder 9 (rotation, vibration) drives the vibrator 6 to move forward and backward and up and down through the extension and contraction of the cylinder rod 46 in the cylinder barrel 53, so that the vibrator 6 can reach any position in the concrete casting bin. The cylinder rod 46 of the vibrating oil cylinder 9 extends downward, causing the vibrating rod 51 to enter the concrete, and drives the flexible shaft 50 to vibrate through the vibrating motor 49, thereby driving the vibrating rod 51 to vibrate the concrete. During the vibration process, the hydraulic control system 28 controls the single or linked movement of the turntable 11 and the oil cylinder 9 (rotation, vibration) to achieve vibration of the entire casting bin surface. Under hydraulic drive, the symmetrically arranged smoothing oil cylinders 9 produce synchronous vertical extension and contraction, driving the smoothing block 20 to move up and down so that it contacts the concrete that needs to be smoothed. At the same time, the synchronous horizontal extension and contraction produced by the horizontal oil cylinder 9 drives the smoothing block 20 to move forward and backward to smooth the concrete. During the smoothing process, the vibrator 32 causes the smoothing block 20 to produce micro-vibrations, which helps to level the coarse aggregate in the concrete. A shock absorber 62 is installed at the connection position between the trowel block 20 and the cylinder rod 46 of the trowel cylinder 9 to reduce the impact of the vibration of the trowel block 20 on the upper trowel mechanism 7.

The ends of the cylinder rods (46) of the smoothing oil cylinders (9) are connected to the smoothing blocks (20) with the exciter (32) in the middle through the shock absorbers (62). Under hydraulic drive, the symmetrically arranged horizontal oil cylinders (9) produce synchronous vertical telescopic movement to drive the smoothing blocks (20) to move up and down, so that the smoothing blocks (20) contact the concrete to be smoothed; the generated synchronous horizontal telescopic movement drives the smoothing blocks (20) to move forward and backward to smooth the concrete. During the smoothing process, the exciter (32) causes the smoothing blocks (20) to generate micro-vibration, which helps to level the coarse aggregate in the poured concrete.

A wheel frame plate (39) and a vertical arm (59) are arranged at the partition position. The wheel frame plates (39) are symmetrically arranged, one of which is fixed to the lower end of the vehicle body (1) and fixed to the frame cross beam (43) at the partition on one side; the other is fixed to the lower end of the vehicle body (1) and fixed to the frame longitudinal beam (38) at one side. The vertical arms (59) are symmetrically arranged, one of which is fixed to the lower end of the vehicle body (1) and fixed to the frame cross beam (43) at the partition on one side; the other is fixed to the lower end of the vehicle body (1) and fixed to the frame longitudinal beam (38) at one side.

8. The small hydraulic slipform concrete pouring vehicle according to claim 2, characterized in that: The vehicle body (1) is located on the poured concrete (34). An oil tank (10), an oil pump (13) and a motor (14) are fixed on the vehicle body (1). The output end of the motor (14) is fixedly connected to the oil pump (13). The oil pump (13) is connected to the oil tank (10) to supply oil to the hydraulic control system (28). A leveling mechanism cross brace (12) is provided at the top end of the cylinder rod (46) of the horizontal oil cylinder (9) on the vehicle body (1). A transverse template (17) is provided at the front end of the symmetrically arranged longitudinal sliding template (5). ), forming a new casting trough with the front edge (18) of the poured concrete, the longitudinal sliding template (5) is fixed with a longitudinal sliding template rib (21) at the middle portion of the outer side of the longitudinal sliding template (5), the transverse template rib (15) is fixed with a transverse template rib (15) at the middle portion of the outer side of the wing plate (23), a wing plate rib (22) is fixed with a vertical plate rib (42) between the wing plate rib (22) and the longitudinal sliding template rib (21), and the lower end of the wing plate (23) is fixedly connected with a wing plate cross brace (19).
