Description

Technical Field

[0001] This utility model belongs to the field of prestressed concrete pipe pile production, and in particular relates to a pipe pile cover mold cleaning machine. Background Technology

[0002] During the production of pipe piles using pipe molds, a large amount of cement slurry adheres to both sides and ends of the mold opening and at the pile joint. If it is not cleaned in time, it will have a significant impact on the product quality of the pipe piles. Therefore, in traditional production, the cement slurry is cleaned manually and a release agent is sprayed during the mold cleaning process in preparation for the production of the next pipe pile.

[0003] However, this manual formwork cleaning method has the following disadvantages: because the mold opening faces downwards, workers need to keep their heads tilted back and forth to clean the cement slurry on the mold, spray the release agent back and forth, and clean up the debris that falls off. This not only results in high labor intensity but also low work efficiency, poor working environment, and negative impact on health. Utility Model Content

[0038] The pipe pile cover formwork cleaning machine includes a front limit photoelectric switch 19 for sensing the tail end of the cover formwork and a rear limit photoelectric switch 20 for sensing the head end of the cover formwork. The front limit photoelectric switch 19 is located at the front end of the front conveyor chain machine 1, and the rear limit photoelectric switch 20 is located at the rear end of the rear conveyor chain machine 2. The front limit photoelectric switch 19 and the rear limit photoelectric switch 20 are respectively connected to an electrical control device.

[0039] The pipe pile cover formwork cleaning machine includes a flip-plate waste pushing device 22 for pushing the cement slag generated during the cleaning of the cover formwork into the waste pit 21. The flip-plate waste pushing device 22 is located at the bottom of the pipe pile cover formwork cleaning machine, and the waste pit 21 is located in front of the flip-plate waste pushing device 22 and directly below the nozzle 18 and the first support roller 6.

[0040] In this embodiment, the tilting garbage pushing device 22 includes a pair of L-shaped fixed frames 23 arranged along the conveying direction, a pair of push-pull cylinders 24, a sweeping frame, multiple push plates 25, and a pull rod 26. The sweeping frame consists of a pair of fixed plates 28, a pair of drive plates 33, multiple vertical connecting plates 29, and rollers 30. One end of the pair of fixed plates 28 has a horizontal cylinder connecting plate 27. The protrusion 41 of the cylinder connecting plate 27 has an elongated opening 31. The other end extends towards the conveying direction. Both ends of each push plate 25 are hinged to the pair of fixed plates 28. Multiple push plates 25 are arranged along the length of the fixed plates 28. The lower end of the connecting plate 29 is connected to the fixed plate 28, and the upper end is rotatably mounted with rollers 30. The cylinder body of each push-pull cylinder 24 is mounted on the top surface of the fixed frame 23 and can roll along the fixed frame 23. The rear end of the cylinder body of each push-pull cylinder 24 is mounted on a vertical plate at one end of the fixed frame 28, and the vertical plate is fixed on the ground 40. The push rod 32 extends in the conveying direction, and the end of the push rod 32 is connected to the drive plate 33. A vertical lever 34 is provided on the lower surface of the drive plate 33. The lever 34 extends into the opening 31. One end of the first pull rod 26 is hinged to the upper surface of the drive plate 33, and the other end is hinged to the top surface of the first push plate 25. The two ends of the remaining pull rods 26 are respectively hinged to two adjacent push plates 25. The push-pull cylinder 24 is connected to the electric control device. The air passage of the push-pull cylinder 24 is connected to compressed air D, and a cleaning solenoid valve 39 is provided on the air passage.

[0041] In other embodiments, such as Figures 7-9The difference between the tipping plate garbage pushing device shown and the above embodiment is that the linkage structure composed of push-pull cylinder 24, drive plate 33, cylinder connecting plate 27, etc. is a group.

[0042] The working principle of the tilting plate garbage pushing device is as follows: The electronic control device controls the push-pull cylinder 24 to extend the push rod 32, thereby driving the lever 34 to move forward along the opening 31. The lever 34 pushes the front edge of the opening 31, thus pushing the sweeping frame forward. At the same time, the roller 30 rolls on the top surface of the fixed frame 23, making the sweeping frame move smoothly. At this time, because the movement of the pull rod 26 is restricted, the push plate 25 remains in a vertical position (see...). Figure 7 The cement residue is pushed forward by the push plate 25 at the end, which pushes the cement residue near the garbage pit 21 into the garbage pit 21. The electronic control device then controls the push rod 32 of the push-pull cylinder 24 to retract, thereby driving the lever 34 to move backward along the opening 31. The first pull rod 26 pulls the first push plate 25 upward, which in turn pulls the remaining push plates 25 upward (see...). Figure 8 At the same time, the sweeping frame moves backward, and the roller 30 rolls on the top surface of the fixed frame 23. Because the push plate 25 flips up, it will not push the cement residue backward.

[0043] The electrical and structural parameters of this utility model are as follows:

[0044] Power supply: AC 380V, 50Hz;

[0045] Air pressure: 0.1-0.6 MPa;

[0046] Power: 22.5KW;

[0047] Cleaning efficiency: 3 minutes / item;

[0048] The cleaning machine's external dimensions are 2600mm × 2100mm × 2000mm (length × width × height).

[0049] The overall working process of this utility model is as follows: Turn on the power switch, hoist the cover mold and place it on the front conveyor chain conveyor. After the front limit photoelectric switch senses the presence of the cover mold, both the front and rear conveyor chain conveyors start simultaneously after a delay. When one end of the cover mold enters the cleaning mechanism, the beaded wire brush and the bristle brush start rotating simultaneously to clean the mold opening and the cement residue on the inner wall of the cover mold. At the same time, the lifting solenoid valve is energized, and the push rod of the lifting cylinder lifts the support frame. When the bristle brush touches the mold opening, the air pressure regulating valve automatically operates to adjust the contact pressure between the bristle brush and the mold opening, preventing excessive cylinder lifting pressure from prematurely damaging the bristle brush. When the rear limit photoelectric switch on the rear conveyor chain conveyor senses the cover mold head… At the end, the electrical control device controls the motor to stop the beaded wire brush and the bristle brush. After a short delay, it controls the motor to drive the front and rear conveyor chains to reverse simultaneously. The spraying solenoid valve will start after a delay, spraying a layer of release agent onto the passing cover mold. At the same time, the cleaning solenoid valve starts working, continuously pushing and pulling the cleaning frame through the push-pull cylinder. The lever moves in the rectangular opening of the fixed plate, allowing the push rod of the push-pull cylinder to pull the push plate backward when it retracts, causing the push plate to flip upward and simultaneously pulling the cleaning frame backward. Then, when the push rod of the push-pull cylinder extends, the push plate is lowered to an upright position, simultaneously pushing the cleaning frame. This repeated movement pushes the cement residue at the bottom of the cleaning machine into the garbage pit. When the front photoelectric switch on the front conveyor chain senses the tail end of the cover mold, it stops the front and rear conveyor chains, the spraying solenoid valve, and the cleaning solenoid valve, and lifts away the cover mold, completing the cleaning process for a single cover mold.

[0050] The embodiments of this utility model are not limited thereto. Based on the above content of this utility model, and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, this utility model can also be modified, replaced or changed in various other forms, all of which fall within the scope of protection of this utility model.
