In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.

Example 1:

as shown in fig. 1, the utility model discloses a release agent spraying device of a concrete pipe pile centrifugal forming die, which comprises a frame 2, wherein wheel seats 3 are arranged at two ends of the frame 2, travelling wheels 8 are arranged on the wheel seats 3, a transmission shaft 4 is arranged on the frame 2, belt wheels 6 are arranged at two ends of the transmission shaft 4, the belt wheels 6 are in transmission connection with the travelling wheels 8 at the same side through a belt 7, the travelling wheels 8 are arranged on two side walls of the concrete pipe pile centrifugal forming die 1, a guide pipe 13 is arranged on the frame 2, one end of the guide pipe 13 is connected with a conveying pump 17 through a hose 14, the conveying pump 17 is arranged in a release agent barrel 16, a hollow connecting body 15 is arranged at the other end of the guide pipe 13, a plurality of spray pipes 18 are arranged on the connecting body 15 at intervals, spray heads 19 are arranged at the end parts of the spray pipes 18, the spray heads 19 are in arc-shaped arrays, the spray heads 19 are positioned in the same vertical plane, and the spray range of the spray heads 19 in the concrete pipe pile centrifugal forming die 1 covers all circumferential areas at a certain axial position of the spray range.

The number of the travelling wheels 8 at each end of the frame 2 can be one or more, so that the frame 2 can stably walk on the side walls of the two sides of the concrete pipe pile centrifugal forming die 1, a belt 7 on the belt wheel 6 can be in transmission connection with the wheel shafts of the travelling wheels 8, the belt 7 can be wound on the travelling wheels 8, a groove can be formed in the circumferential surface of the travelling wheels 8, and the belt 7 is located in the groove to ensure that the belt 7 cannot fall off in the running process. The thickness of the belt 7 can be larger than that of the groove, so that the rubber belt 7 can be directly contacted with the side wall of the centrifugal forming die 1 of the concrete pipe pile, and damage to the die 1 is avoided. A motor 5 and a transmission shaft 4 are adopted to drive a belt wheel 6 and a travelling wheel 8 to move, so that stable and synchronous travelling of the belt wheel and the travelling wheel can be kept. In the running process, the delivery pump 17 delivers the release agent in the release agent barrel 16 into the connecting body 15 through the hose 14 and the guide pipe 13, and the release agent is sprayed out from the spray head 19 at the end part of the spray pipe 18, so that the release agent can be uniformly sprayed on the inner surface of the centrifugal forming die 1 of the concrete pipe pile, and the spraying amount of the release agent is always uniform when the machine frame 2 stably runs on the die 1 at a uniform speed. According to the inner diameter of the die 1, the number of the spray heads 19, the distance between the spray heads 19 and the inner wall of the die 1 and the range in which the spray heads 19 can spray to cover, the spray heads 19 are reasonably arranged, so that the mold release agent sprayed by the spray heads 19 can be ensured to fully cover in the circumferential range corresponding to a certain axial position of the frame 2 in the die 1. When the frame 2 walks once in the axial direction of the die 1, the spray head 19 can uniformly spray the inner surface of the die 1 and fully cover the die, so that the situation that the concrete pipe pile is difficult to demould after being molded due to partial omission is avoided.

The outer sides of the wheel seats 3 at the two ends of the frame 2 are provided with outward protruding portions 9, the protruding portions 9 are rotatably provided with a retainer 10 through pin shafts, the lower end of the retainer 10 is provided with a pressing wheel 11, the pressing wheel 11 is rotatably connected with the retainer 10, the axial direction of the pressing wheel 11 is vertically upwards arranged, a pressure spring 12 is arranged between the upper end of the retainer 10 and the frame 2, in a natural state, the pressure spring 12 is in a compressed state, and the pressing wheel 11 is in contact with the outer wall of the centrifugal forming die 1 of the concrete pipe pile. The compression spring 12 and the pinch roller 11 are respectively arranged at two ends of the retainer 10, and the middle part of the retainer 10 is rotationally connected with the protruding part 9 through a pin shaft, so that under the action of the compression spring 12, the pinch roller 11 approaches one side of the centrifugal forming die 1 of the concrete pipe pile and applies certain pressure, so that the pinch roller is supported at the outer side of the die 1, and the pinch rollers are supported at two sides, thereby promoting the frame 2 to stably walk on the die 1. When the pressure wheel is in contact with the die 1, the pressure spring 12 is still in a certain compression state, so that pressure can be applied to the pressure wheel, but the pressure spring 12 is not in a complete compression state, so that the pressure wheel is more conveniently separated from the die 1 under the action of external force, and the whole device can be taken down.

The adjacent spray pipes 18 are fixedly connected through a connecting rod 20. The adjacent spray pipes 18 are fixed through the connecting rods 20, so that the spray pipes 18 are more stable, and the spray range of the spray heads 19 is more stable and reliable in the moving process of the frame 2, so that the situation that the release agent is not sprayed locally can be avoided.

The spacing between all spray heads 19 and the inner wall of the concrete pipe pile centrifugal forming die 1 at the corresponding position is the same. The same spacing allows the coverage of each spray head 19 to be substantially uniform, and the amount of release agent sprayed by each spray head 19 to be substantially uniform, so that the amount of release agent sprayed at each location on the mold 1 is substantially uniform and the spray is more uniform and reliable.
