Description

Technical Field

[0001] This utility model relates to the technical field of mold surface cleaning equipment, specifically to a vertical cleaning and spraying device for PCCP pipe outer mold. Background Technology

[0002] PCCP pipe, or prestressed concrete cylinder pipe, is made by pouring high-strength concrete on both the inner and outer sides of a steel cylinder. After demolding, the mold used needs to be cleaned before reuse. Currently, cleaning the inner surface of the PCCP pipe outer mold usually requires manual entry into the mold. The dust generated during cleaning not only affects the operator's vision and reduces construction efficiency, but may also lead to incomplete cleaning and pose a certain threat to the operator's health. After cleaning, manual spraying is required. During spraying, if the PCCP pipe outer mold is high, hoisting equipment is needed for assistance. Manual spraying in multiple sections results in poor spray uniformity, poses certain safety hazards, and affects the subsequent demolding effect. Utility Model Content

[0003] The purpose of this invention is to provide a vertical cleaning and spraying device for the outer mold of PCCP pipe, which solves the problems of long time consumption, incomplete cleaning and poor spraying uniformity in the existing technology of manual operation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A vertical cleaning and spraying device for PCCP pipe outer mold includes a support chuck, a rotary assembly, a vertical support rod, a vertical drive assembly, a horizontal drive assembly, a support member, a cleaning assembly, and a spraying assembly. The PCCP pipe outer mold is mounted on the support chuck. The rotary assembly is located at the middle position of the support chuck and is used to drive the vertical support rod to rotate. The vertical drive assembly is slidably mounted on the vertical support rod and is used to drive the horizontal drive assembly to slide vertically along the vertical support rod. The support member is mounted on the horizontal drive assembly, and the horizontal drive assembly drives the support member to slide horizontally. The cleaning assembly is located at one end of the support member and is used to clean the inner surface of the PCCP pipe outer mold. The spraying assembly is located at the other end of the support member and is used to spray the inner surface of the PCCP pipe outer mold.

[0005] Preferably, the support chuck includes a support base and three sets of pneumatic grippers disposed on the support base, the three sets of pneumatic grippers being evenly distributed circumferentially on the top of the support base.

[0006] Preferably, the support chuck is annular, and the rotary assembly is located at the bottom center of the support chuck.

[0007] Preferably, the rotary assembly includes a rotary support, a rotary drive motor, a rotary drive gear, a support plate, and a rotary driven gear; the rotary drive motor is fixedly mounted on the rotary support via a motor bracket; the rotary drive gear is fixedly mounted on the output shaft of the rotary drive motor; the rotary driven gear is rotatably mounted on the rotary support, and the rotary drive gear meshes with the rotary driven gear; the support plate is fixedly mounted on the rotary driven gear, and the vertical support rod is fixedly mounted on the support plate.

[0008] Preferably, both the vertical drive component and the horizontal drive component are servo motor linear modules.

[0009] Preferably, the cleaning assembly includes a pneumatic motor, a stainless steel brush disc, and a high-pressure air nozzle. The pneumatic motor is fixedly mounted on the support member, and the stainless steel brush disc is fixedly mounted on the output end of the pneumatic motor. The pneumatic motor can drive the stainless steel brush disc to rotate rapidly. The high-pressure air nozzle is fixedly mounted on the support member and is used to blow away debris.

[0010] Preferably, the spraying assembly is an electrostatic spraying gun head, used to spray a release agent onto the inner surface of the PCCP pipe outer mold.

[0011] In this invention, the PCCP pipe outer mold is positioned and installed by a support chuck, which ensures the stability of the PCCP pipe outer mold during the entire operation process, improves the safety of the operation, and facilitates subsequent cleaning and spraying operations after the PCCP pipe outer mold is positioned.

[0012] The rotating component, vertical drive component, and horizontal drive component are linked and controlled to drive the cleaning component and spraying component to work according to the preset trajectory. This allows for comprehensive cleaning and spraying of the inner surface of the PCCP pipe outer mold. Furthermore, the rotating component, vertical drive component, and horizontal drive component can match different working speeds according to the working speed and coverage area of ​​the cleaning component and spraying component, thereby improving work efficiency.

[0013] The cleaning component uses a rapidly rotating stainless steel brush to thoroughly clean the inner surface of the PCCP pipe outer mold, and uses a high-pressure air nozzle to blow away debris, preventing debris from remaining on the inner surface of the PCCP pipe outer mold and improving the cleaning effect.

[0014] The cleaning and spraying components are respectively arranged at both ends of the support. Cleaning and spraying are carried out in separate times to avoid cross-contamination. Moreover, spraying can be carried out directly after cleaning is completed, reducing idle travel time and improving work efficiency. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 3 The illustrated vertical cleaning and spraying device for PCCP pipe outer molds includes a support chuck 1, a rotating assembly 2, a vertical support rod 3, a vertical drive assembly 4, a horizontal drive assembly 5, a support component 6, a cleaning assembly 7, and a spraying assembly 8. The PCCP pipe outer mold 9 is mounted on the support chuck 1. After demolding, the PCCP pipe outer mold 9 is hoisted onto the support chuck 1, awaiting cleaning and spraying operations. The support chuck 1 includes a support base 10 and three sets of pneumatic grippers 11 mounted on the support base 10. The three sets of pneumatic grippers 11 are circumferentially distributed on the top of the support base 10. The support chuck 1 is generally annular in shape. The three sets of pneumatic grippers 11 can vertically position and fix the PCCP pipe outer mold 9. A wear-resistant rubber layer is provided at the end of the pneumatic gripper 11 that contacts the PCCP pipe outer mold 9. The device is controlled by a PLC programmable controller. The slewing assembly 2 is positioned in the middle of the support chuck 1 and is used to drive the vertical support rod 3 to rotate. Specifically, the slewing assembly 2 is fixedly located at the bottom center of the support chuck 1. The slewing assembly 2 includes a slewing support 20, a slewing drive motor 21, a slewing drive gear 22, a support plate 23, and a slewing driven gear 24. The slewing drive motor 21 is fixedly mounted on the slewing support 20 via a motor bracket. The slewing support 20 is fixedly located at the bottom center of the support chuck 1.

[0017] A rotary drive gear 22 is fixedly mounted on the output shaft of a rotary drive motor 21. A rotary driven gear 24 is rotatably mounted on a rotary support 20. The rotary drive gear 22 and the rotary driven gear 24 are meshed together. When the rotary drive motor 21 is energized and rotates, the rotary drive gear 22 rotates accordingly, driving the rotary driven gear 24 to rotate. A support plate 23 is fixedly mounted on the rotary driven gear 24, and the bottom of the vertical support rod 3 is fixedly mounted on the support plate 23. The vertical center of the vertical support rod 3 coincides with the axis of the rotary driven gear 24. The rotary drive motor 21 is selected as a servo motor or a stepper motor, which can control the speed and start / stop according to the speed and position requirements of the operation.

[0018] The vertical drive assembly 4 is slidably mounted on the vertical support rod 3 and is used to drive the horizontal drive assembly 5 to slide vertically along the vertical support rod 3. The vertical drive assembly 4 is a servo motor linear module, which can control the movement speed and position according to the speed and position requirements of the operation.

[0019] The horizontal drive assembly 5 is fixedly mounted on the vertical drive assembly 4. The horizontal drive assembly 5 uses a servo motor linear module, capable of controlling the movement speed and position according to the speed and position requirements of the operation. The support member 6 is mounted on the horizontal drive assembly 5, and the horizontal drive assembly 5 drives the support member 6 to slide horizontally. To save costs, the horizontal drive assembly 5 includes a horizontal drive motor 50 fixedly mounted on the vertical drive assembly 4, a first gear 51 fixedly mounted on the output end of the horizontal drive motor 50, a rack 52 fixedly mounted on the support member 6, and a slide rail 53 fixedly mounted on the vertical drive assembly 4. The support member 6 is slidably mounted within the slide rail 53. The vertical drive assembly 4 drives the horizontal drive motor 50 and the slide rail 53 to move vertically. The first gear 51 meshes with the rack 52. When the horizontal drive motor 50 is energized and rotates, the first gear 51 rotates accordingly, driving the rack 52 to move linearly, causing the support member 6 to slide within the slide rail 53. The horizontal drive motor 50 can be a servo motor or a stepper motor, enabling precise control according to the position requirements of the operation.

[0020] The cleaning assembly 7 is located at one end of the support member 6 and is used to clean the inner surface of the PCCP pipe outer mold 9. The cleaning assembly 7 includes a pneumatic motor 70, a stainless steel brush disc 71, and a high-pressure air nozzle 72. The pneumatic motor 70 is fixedly mounted on the support member 6, and the stainless steel brush disc 71 is fixedly mounted on the output end of the pneumatic motor 70 with fasteners. The pneumatic motor 70 can drive the stainless steel brush disc 71 to rotate rapidly (500-3000 rpm). The high-pressure air nozzle 72 is fixedly mounted on the support member 6 and is used to blow away the debris cleaned by the stainless steel brush disc 71. The pneumatic motor 70 and the high-pressure air nozzle 72 are connected to an air pump via air pipes and a solenoid valve, and the air pump provides the gas required for their operation. Alternatively, an electric motor can be used to replace the pneumatic motor 70.

[0021] The spraying assembly 8 is located at the other end of the support member 6 and is used to spray the inner surface of the PCCP pipe outer mold 9. The spraying assembly 8 is an electrostatic spraying gun head, equipped with a flow feedback valve and an atomization controller, used to spray the release agent onto the inner surface of the PCCP pipe outer mold 9. In one specific embodiment, one end of the electrostatic spraying gun head is connected to a high-pressure water pump through a pipe, and the high-pressure water pump squeezes the release agent and delivers it to the electrostatic spraying gun head.

[0022] During operation, the PCCP pipe outer mold 9 is first hoisted onto the support chuck 1 using an overhead crane. A laser alignment system is then used to center the PCCP pipe outer mold 9 on the support chuck 1. Three sets of pneumatic grippers 11 then clamp and center the PCCP pipe outer mold 9. After clamping, the three sets of pneumatic grippers 11 send pressure signals back to the PLC program controller, completing the clamping process.

[0023] The PLC program controller directs the cleaning assembly 7 to the starting point at the bottom of the PCCP pipe outer mold 9. The rotary assembly 2, vertical drive assembly 4, and horizontal drive assembly 5 perform spiral motion under the control of the PLC program controller. The cleaning assembly 7 rises along a spiral path (pitch 20-50cm), with a pressure of 0.3-0.5MPa on the stainless steel brush disc 71 and a travel speed of 0.5-2m / min.

[0024] After cleaning, the PLC program controller directs the spraying assembly 8 to the starting point at the top of the PCCP pipe outer mold 9. The spraying assembly 8 descends along a spiral path, and the electrostatic spraying gun head, equipped with a flow feedback valve and an atomization controller, atomizes and sprays the release agent. The release agent pressure during spraying is 0.2-0.4 MPa, the film thickness is controlled at 50-100 μm, and the overlap rate is ≥30%.

[0025] After the spraying is completed, the rotary assembly 2, the vertical drive assembly 4 and the horizontal drive assembly 5 return to their initial positions, the three sets of pneumatic grippers 11 are released, the overhead crane moves out of the PCCP pipe outer mold 9, and the entire device enters standby mode, waiting for the next operation.

[0026] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
