Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pipe segment moulds, and in particular relates to a pressing device for automatic cleaning of concrete pipe segment moulds. Background Art

[0002] At present, the common cleaning work of concrete segment molds after demoulding is done manually, and the use of robots to clean the molds is relatively rare. When using robots for cleaning, a key problem needs to be solved, that is, how to ensure that the degree of compression between a cleaning tool (such as a brush) and the inner cavity of the mold is appropriate. The current solution is to adjust the movement of the robot's mechanical arm. However, this method has certain limitations due to the limitations of the robot's mechanical arm, including slow movement speed, low efficiency, and often different degrees of compression, which will cause some places to be pressed too tightly and seriously affect the service life of the brush, and some places to be pressed too loosely, resulting in poor cleaning effect. For this reason, a clamping device for automatic cleaning of concrete segment molds is proposed. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, a clamping device for automatic cleaning of concrete segment molds provided by an embodiment of the utility model includes an integral bracket 6, to which two symmetrically arranged lifting rails 7 are fixedly connected, and further includes:

[0027] Bracket 3;

[0028] Walking guide wheels 5, both sides of the bracket 3 are rotatably connected with walking guide wheels 5, and the walking guide wheels 5 roll along the lifting track 7;

[0029] A clamping cylinder 1, wherein a connecting seat 9 is hingedly connected to the clamping cylinder 1, and the connecting seat 9 is fixedly connected to the integral bracket 6, and a cylinder joint of the clamping cylinder 1 is connected to the bracket 3;

[0030] A position sensing switch 8, wherein the position sensing switch 8 is mounted on the pressing cylinder 1;

[0031] A cleaning tool 4, wherein the cleaning tool 4 is rotatably disposed on the bracket 3, and an input end of the cleaning tool 4 is provided with a driving assembly, and the driving assembly is fixedly disposed on the bracket 3;

[0032] The distance angle sensing switch 2 is fixedly connected to the integral bracket 6. The distance angle sensing switch 2 is used to send the current position signal to the central data processor. The central data processor is used to read the position data of the position sensing switch 8 after receiving and processing the signal, and control the movement of the piston rod of the clamping cylinder 1.

[0033] In the embodiment of the utility model, when in use, the pipe segment mold is moved to the front end of the robot, and the robot arm is controlled by the robot program to move along the inner shape of the pipe segment mold. At the same time, the rotating motor 10 is turned on to drive the cleaning tool 4 to rotate to realize the cleaning work of the inner cavity of the pipe segment mold. At this time, the distance angle sensing switch 2 detects whether the distance angle between the cleaning tool 4 and the mold inner cavity meets the program setting. If not, the distance angle sensing switch 2 will send the current position signal to the central data processor. After the central data processor processes the data, it reads the position data of the position sensing switch 8 on the clamping cylinder 1 and sends a piston position adjustment signal. The adjustment signal controls the proportional valves on both sides of the clamping cylinder 1 to achieve the pressure difference on both sides of the clamping cylinder 1, thereby pushing the piston position change, thereby generating an outward thrust or pulling force through the piston rod, so that the bracket 3 can achieve up and down position change in the lifting track 7 through the walking guide roller 5, thereby driving the cleaning tool 4 to achieve up and down position change, thereby achieving the fixed distance between the cleaning tool 4 and the mold inner cavity surface predetermined by the program.

[0034] like Figure 1 As shown, as a preferred embodiment of the utility model, the driving assembly includes:

[0035] A rotating motor 10, wherein the rotating motor 10 is fixedly arranged on the bracket 3;

[0036] The bevel gear conversion box 11 is fixedly arranged on the bracket 3 , the input end of the bevel gear conversion box 11 is connected to the output end of the rotating motor 10 , and the output end of the bevel gear conversion box 11 is connected to the cleaning tool 4 .

[0037] In the embodiment of the utility model, two meshing bevel gears are provided in the bevel gear conversion box 11, the output end of the rotating motor 10 is connected to one bevel gear, and the other bevel gear is connected to the cleaning tool 4. When the rotating motor 10 is turned on, the rotating motor 10 drives the bevel gear connected to it to rotate, and the bevel gear drives the other bevel gear to rotate, thereby driving the cleaning tool 4 to rotate to realize the cleaning work of the inner cavity of the pipe segment mold.

[0038] like Figure 1 As shown, as a preferred embodiment of the present utility model, the cleaning tool 4 is a cleaning brush.

[0039] The working principle of the utility model is:

[0040] The clamping device for automatic cleaning of concrete segment molds, when in use, moves the segment mold to the front end of the robot, controls the robot arm to move along the inner shape of the segment mold through the robot program, and starts the rotary motor 10 to drive the cleaning brush to rotate, so as to realize the cleaning of the segment mold inner cavity. At this time, the distance angle sensing switch 2 detects whether the distance angle between the cleaning brush and the mold inner cavity meets the program setting. If not, the distance angle sensing switch 2 will send the current position signal to the central data processor. After the central data processor processes the data, it reads the position data of the position sensing switch 8 on the clamping cylinder 1 and sends a piston position adjustment signal. The adjustment signal controls the proportional valves on both sides of the clamping cylinder 1 to realize the pressure difference on both sides of the clamping cylinder 1, thereby pushing the piston position change, thereby generating an outward thrust or pulling force through the piston rod, so that the bracket 3 realizes the up and down position change in the lifting track 7 through the walking guide roller 5, and then drives the cleaning brush to realize the up and down position change, thereby achieving the fixed distance between the cleaning brush and the mold inner cavity surface predetermined by the program, maintaining a stable pressure, optimizing the cleaning process, improving the cleaning quality, and extending the service life of the cleaning tool.

[0041] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
