Abstract
Description
Technical Field
[0001] This utility model relates to the field of template painting technology, and more specifically, to an automatic template painting device. Background Technology
[0002] Applying oil to box girder formwork is a crucial step in bridge construction, directly affecting the appearance quality of the concrete, the release effect, and the service life of the formwork. Box girder manufacturing is generally carried out in beam factories, which construct many box girder bases. The bottom formwork is placed on the box girder bases and then coated with an oil-based release agent. In the specific application process, workers use a roller brush to apply the oil-based release agent to the surface of the formwork. This oiling step is quite tedious, requiring workers to move around constantly, which is physically demanding. Furthermore, the roller brush needs to be constantly dipped in the release agent, and during the application process and personnel movement, the oil-based release agent is prone to dripping onto the ground, resulting in waste. Utility Model Content
[0003] The purpose of this utility model is to provide an automatic template painting device that reduces waste and is easy to operate.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic template oiling device includes an oil tank, with lifting seats fixedly installed at both ends of the bottom of the oil tank, and a movable seat provided below the lifting seats. A push cylinder is installed in the middle of the movable seat, and the piston shaft of the push cylinder is fixedly connected to the corresponding lifting seat. A drive wheel is installed at the bottom of the movable seat, and multiple oiling rollers are rotatably installed between the two lifting seats. Multiple overflow pipes are evenly installed at the bottom of the oil tank at the position of the oiling rollers. The overflow pipes are used to transport the oily release agent in the oil tank to the surface of the oiling rollers.
[0005] Preferably, the upper part of the movable seat has three sliding grooves, the push cylinder is fixedly installed in the sliding groove in the middle position, and the bottom ends of the lifting seat are fixedly installed with limit plates, and the two limit plates are respectively movably inserted into the sliding grooves on both sides.
[0006] Preferably, bearings are fitted on both ends of the brush roller shaft, and a vertical groove is provided on the inner side of the lifting seat at the brush roller position. The bearing is located in the vertical groove, and a spring is fixedly installed at the top of the vertical groove, with the lower end of the spring in elastic contact with the bearing.
[0007] Preferably, the oil overflow pipe includes a drain pipe, the upper end of which is connected to the oil tank through an oil hole, and the lower end of which is provided with a limiting groove filled with an oil-absorbing sponge, the lower end of which is in contact with the oil brushing roller.
[0008] Preferably, the drive wheel is an AGV drive wheel.
[0009] Preferably, the top of the oil tank is provided with an oil filling port.
[0010] Preferably, a vent valve is installed on the top of the oil tank.
[0011] Compared with the prior art, the advantages of this utility model are:
[0012] This invention enables automatic oiling of the bottom formwork of box girders. It has a wide range of applications. The height of the lifting seat can be controlled by the push cylinder, allowing the oiling roller to adapt to box girder bases of different heights. The oil overflow pipe can limit the oil flow rate, preventing the oil-based release agent from spilling out and effectively avoiding waste of the oil-based release agent. The oiling roller contacts the bottom formwork of the box girder base and is driven by the drive wheel to move the whole unit, thereby evenly applying the oil-based release agent to the bottom formwork, improving oiling efficiency and reducing the labor intensity of workers.
