Description

Technical Field

[0001] This utility model relates to the technical field of release agent spraying equipment, and in particular to a release agent spraying device for precast T-beam molds. Background Technology

[0002] T-beam molds are used to manufacture T-beams, a common type of precast concrete component widely used in bridge construction and other fields. Before pouring the concrete, a release agent is sprayed inside the T-beam mold to form an isolation film on the inner wall of the mold. This effectively reduces the adhesion between the concrete and the mold, allowing the concrete to be easily removed from the mold after it reaches a certain strength. This avoids problems such as surface damage and edge collapse caused by sticking and difficulty in demolding, thus ensuring the integrity of the T-beam.

[0003] However, in actual construction, when spraying release agent onto the inner surface of the T-beam mold, manual spraying is often used, which is inefficient, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a release agent spraying device for precast T-beam molds, which is time-saving, labor-saving, and highly efficient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a release agent spraying device for precast T-beam molds, comprising a beam frame, a liquid storage tank fixedly connected to the inner bottom surface of the beam frame, two hydraulic cylinders fixedly connected to the bottom surface of the beam frame, a movable plate fixedly connected to the bottom end of the two hydraulic cylinders, L-shaped tubes provided on both the left and right sides of the bottom of the movable plate, a movable component provided at the bottom of the movable plate, the movable component being used to drive the L-shaped tubes to move laterally left and right, a horizontal pipe fixedly connected to the bottom of the L-shaped tubes via a connecting pipe, a solenoid valve fixedly connected to the connecting pipe, an atomizing nozzle fixedly connected to the side of the L-shaped tube away from the movable plate and the bottom surface of the horizontal pipe, a connecting hose fixedly connected to the inlet of the L-shaped tube, a high-pressure pump fixedly connected to the other end of the connecting hose, the high-pressure pump fixedly connected to the bottom of the beam frame, and the high-pressure pump connected to the bottom of the liquid storage tank via a hose.

[0006] Furthermore, an atomizing nozzle is also fixedly connected to the outer side of the bend of the L-shaped tube.

[0007] Furthermore, the aforementioned moving component includes a strip-shaped groove, which is formed at the bottom of the moving plate and is aligned with the length direction of the moving plate. A motor is fixedly connected to the right surface of the groove, and a bidirectional lead screw is rotatably connected to the left inner wall of the groove. Threaded sleeves are connected to both sides of the bidirectional lead screw with reverse threads. A connecting rod is fixedly connected to the outer side of the threaded sleeve, and the connecting rod is fixedly connected to an L-shaped tube. The threaded sleeve is in close contact with the inner wall of the groove and can slide along the length direction of the groove.

[0008] Furthermore, an angled spray head is fixedly connected to the bottom of the aforementioned horizontal tube near the center of the moving plate.

[0009] Furthermore, an arc-shaped protective plate is fixedly connected to the bottom of the aforementioned movable plate, and a baffle is fixedly connected to the inner side of the horizontal section of the L-shaped tube.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1) By using two hydraulic cylinders to drive the telescopic moving plate, L-shaped pipe, moving components, connecting pipe, horizontal pipe, solenoid valve, atomizing nozzle, connecting hose and high pressure pump, the spray range can be adjusted according to the width of the T-beam mold, ensuring that the spraying position is at the optimal distance from the inner wall of the mold, thereby ensuring uniform atomization effect and avoiding spraying dead corners that would affect the demolding effect. It can be attached to the crane to move and spray, saving time and labor and greatly improving efficiency.

[0012] 2) The angled spray nozzles can fill the gap between the horizontal pipes on both sides when they are unfolded, thus improving the spraying efficiency. The combination of the arc-shaped protective plate and the baffle can shield and protect the outside of the moving components, reducing the contact between the spray and the double-ended screw and other structures, thereby extending the service life of the device.

[0013] (3) The specific structural settings of the moving component can quickly realize the rapid position adjustment of the L-shaped tube and the horizontal tube, making the movement fast and convenient, and quickly adapting to the mold width requirements. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example 1: Refer to Figures 1-4 A release agent spraying device for precast T-beam molds includes a beam frame 1. A detachable lifting lug is fixedly connected to the upper surface of the beam frame 1. The beam frame 1 is used in conjunction with an overhead crane, and a hook assembly is installed on the crane. The hook assembly connects to the lifting lug on the beam frame 1, allowing the spraying device to move vertically. During crane operation, the spraying device moves slowly and uniformly along the length of the mold, enabling comprehensive spraying of the T-beam's interior. A liquid storage tank 2 is fixedly connected to the bottom surface of the beam frame 1, and an inlet pipe is fixedly connected to the top of the liquid storage tank 2. A sealing cap is threaded onto the top of the inlet pipe, allowing the release agent to be added to the liquid storage tank 2. A hydraulic cylinder 3 is fixedly connected to the bottom surface of the beam frame 1, and a moving plate 4 is fixedly connected to the bottom end of the hydraulic cylinder 3. When the hydraulic cylinder 3 is activated, it drives the moving plate 4 vertically. The linear motion is achieved using two hydraulic cylinders 3. These two cylinders limit each other, ensuring that components such as the lower moving plate 4 can only move in a linear up-down direction, preventing rotational deviation that could affect the accuracy of the spraying. Atomizing nozzles 10 are fixedly connected to the side of the L-shaped tube 5 away from the moving plate 4 and to the bottom surface of the horizontal tube 8. A connecting hose 11 is fixedly connected to the inlet of the L-shaped tube 5, and a high-pressure pump 12 is fixedly connected to the other end of the connecting hose 11. The high-pressure pump 12 is fixedly connected to the bottom of the beam frame 1 and is connected to the bottom of the liquid storage tank 2 via a hose. L-shaped tubes 5 are located on both the left and right sides of the bottom of the moving plate 4. Atomizing nozzles 10 are also fixedly connected to the outer side of the bends in the L-shaped tubes 5. The atomizing nozzles 10 at the bends of the L-shaped tubes 5 can spray the area at the bends on the bottom surface of the mold.

[0022] A moving component 6 is provided at the bottom of the moving plate 4. The moving component 6 is used to drive the L-shaped tube 5 to move left and right laterally. The moving component 6 includes a strip-shaped groove 61, which is opened at the bottom of the moving plate 4 and is consistent with the length direction of the moving plate 4. A motor 62 is fixedly connected to the right surface of the groove 61. The left motor shaft of the motor 62 passes through the moving plate 4. The left motor shaft of the motor 62 is fixedly connected to the right end of the bidirectional lead screw 63. The bidirectional lead screw 63 is rotatably connected to the left inner wall of the groove 61. The left motor shaft of the motor 62 is fixedly connected to the right end of the bidirectional lead screw 63. When the motor 62 is started, it can drive the bidirectional lead screw 63. The rod 63 rotates, and the left and right sides of the bidirectional lead screw 63 are connected to threaded sleeves 64 by reverse threads. The threaded sleeves 64 are slidably connected to the inside of the groove 61. The groove 61 can guide and limit the movement of the threaded sleeves 64, that is, directional movement, so that the threaded sleeves 64 can only perform linear movement in the left and right directions. A connecting sleeve is provided on the outer bottom of the threaded sleeve 64, and a connecting rod 65 is fixedly connected to the connecting sleeve. When the threaded sleeve 64 moves, it can drive the connecting rod 65 to move synchronously. The two connecting rods 65 provided on the left and right sides below the moving plate 4 are fixedly connected to the L-shaped tubes 5 on the left and right sides of the moving plate 4, respectively.

[0023] When the motor 62 starts and drives the bidirectional lead screw 63 to rotate, it can drive the threaded sliding sleeves 64 on the left and right sides to move in opposite directions synchronously under the limit of the groove 61. Then, it can drive the L-shaped tubes 5 on both sides to move synchronously through the connecting rod 65. During this process, the distance between the two L-shaped tubes 5 on the left and right sides can be adjusted.

[0024] Reference Figures 2-4 The bottom of the L-shaped tube 5 is fixedly connected to a horizontal tube 8 via a connecting pipe 7. When the L-shaped tube 5 moves, the horizontal tube 8 can move synchronously through the connecting pipe 7. The release agent that enters the L-shaped tube 5 can enter the horizontal tube 8 through the connecting pipe 7. A solenoid valve 9 is fixedly connected to the connecting pipe 7, which can control the opening and closing of the connecting pipe 7. Atomizing nozzles 10 are fixedly connected to the side of the L-shaped tube 5 away from the moving plate 4 and the bottom surface of the horizontal tube 8. The high-pressure liquid that enters the L-shaped tube 5 and the atomizing nozzle 10 can be atomized and sprayed out through the atomizing nozzle 10. A connecting hose 11 is fixedly connected to the inlet of the L-shaped tube 5. A high-pressure pump 12 is fixedly connected to the other end of the connecting hose 11. The high-pressure pump 12 is fixedly connected to the bottom of the beam frame 1. The high-pressure pump is fixedly connected to the bottom surface of the storage tank 2 through the hose and communicates with its interior. When the high-pressure pump 12 is started, it can draw the release agent liquid inside the storage tank 2 into the L-shaped tube 5 and pressurize the release agent liquid.

[0025] Reference Figure 2 and Figure 4A slanted spray head 13 is fixedly connected to the bottom of the horizontal pipe 8 near the center of the moving plate 4. The slanted spray head 13 is inclined towards the center of the moving plate 4. The slanted spray head 13 can spray the gap between the two horizontal pipes 8 on the left and right sides. An arc-shaped protective plate 14 is fixedly connected to the bottom of the moving plate 4. The arc-shaped protective plate 14 can shield and protect the bottom of the groove 61, reducing the atomized liquid entering the groove 61 when the bottom of the horizontal pipe 8 is sprayed. A baffle 15 is fixedly connected to the inner side of the horizontal section of the L-shaped pipe 5. The baffle 15 can shield and protect the left and right sides of the moving plate 4, reducing the spray moving towards the moving plate 4 when the outside of the L-shaped pipe 5 is sprayed, thereby reducing the impact on the moving component 6.

[0026] Working principle: The beam frame 1 is connected to the hook assembly on the overhead crane via the lifting lugs. When the overhead crane is running, the hook assembly can drive the entire spraying device to move and spray along the length of the mold. The hook assembly can also drive the spraying device to move up and down significantly to achieve rapid height adjustment. The overhead crane power supply and device control system are connected via a spiral telescopic cable to achieve power supply and signal transmission. The top sealing cover of the liquid storage tank 2 is opened, and an appropriate amount of release agent is injected through the liquid inlet pipe. The overhead crane runs along the track to the starting position at one end of the T-beam mold. The laser positioning system ensures that the device is aligned with the center line of the T-beam mold. Then, the entire spraying device is lowered to the bottom of the mold via the hook assembly. Then, the hydraulic cylinder 3 is activated, driving the moving plate 4 to descend to the preset height, precisely adjusting the position of the spraying components below to improve the accuracy of spraying.

[0027] Motor 62 drives bidirectional lead screw 63 to rotate, causing threaded sleeve 64 to move in the opposite direction along groove 61. Through connecting rod 65, it drives the two L-shaped tubes 5 on both sides to expand outward, so that the L-shaped tubes 5 move towards the wider part of the bottom surface of the mold, and then approach the bottom protrusion. Then, high pressure pump 12 starts to draw out the release agent from the liquid storage tank 2 and pressurize it into the L-shaped tube 5. At this time, solenoid valve 9 opens, so that liquid can also enter the horizontal tube 8. Then, the release agent can be evenly sprayed onto the bottom surface of the mold and the inner wall of the protrusion through the atomizing nozzles 10 on the outside of L-shaped tube 5 and horizontal tube 8. The angled spray nozzle 13 sprays towards the center to fill the gap area between the two horizontal tubes 8. Thus, the spraying of the bottom surface of the mold and the inner wall of the protrusion can be completed in one go under the operation of the crane.

[0028] Then, the motor 62 can be started to drive the L-shaped tubes 5 on both sides to retract and adjust to fit the upper width inside the mold. Then, the L-shaped tubes 5 can be moved up to the upper inside of the mold by the hook assembly, and the solenoid valve 9 is closed, so that the device only sprays the upper inner wall of the mold, avoiding repeated spraying of the bottom surface of the mold and causing waste. With the lateral movement of the overhead crane, the upper inside of the mold can be sprayed, avoiding dead corners and improving spraying efficiency. During the spraying process, the arc-shaped protective plate 14 and the baffle 15 can shield and protect the bottom and left and right sides of the moving plate 4, reducing the impact of the spray on the moving component 6 and extending the service life of the device.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
