Due to manual operation, it is difficult to control the strength and uniformity of the workers' operation. If the pressure is too small, it is difficult to smooth the hard parts of the plane. If the pressure is too large, the plane will sag, affecting the quality of the pipe segment. Utility Model Content

[0038] The existing plastering method is that two workers pull a long pole to rub back and forth along the curved surface of the pipe segment, which is labor-intensive and inefficient. Due to manual operation, it is difficult to control the strength and uniformity of the workers' operation. If the pressure is too small, the hardness of the surface is not easy to smooth. If the pressure is too large, the surface will be concave, affecting the quality of the pipe segment, which is a high problem.

[0039] In order to solve the above problems, the utility model provides an automatic surface wiping device 100. Figure 1 The present invention is a specific embodiment of the automatic wiping equipment provided by the utility model.

[0040] See also Figure 1 The automatic plastering equipment 100 includes a base 1, a mobile structure 2, and a plastering mechanism 3. The mobile structure 2 includes a fixed part 21 and a mobile part 22. The fixed part 21 is installed on the base 1. The mobile part 22 is installed on the fixed part 21 in a longitudinal direction. The plastering mechanism 3 includes a lifting structure 31 and a plastering structure 32. The plastering structure 32 is arranged at the lower end of the lifting structure 31. The lifting structure 31 is installed on the mobile part 22 and can drive the plastering structure 32 to move in the up and down directions.

[0041] In the technical solution provided by the utility model, the automatic plastering equipment 100 has a plastering station. When the mold containing the pipe segment moves to the plastering station, the moving part 22 drives the plastering mechanism 3 to move longitudinally to above the plastering station. After the lifting structure 31 and the plastering structure 32 are in place, the operator can control the lifting structure 31 to drive the plastering structure 32 to move up and down according to the model of the mold, so that the plastering structure 32 can abut against the part of the arc surface of the mold. After that, the plastering structure 32 starts to plaster the surface of the pipe segment. At this time, the moving part 22 continues to drive the lifting structure 31 and the plastering structure 32 to move longitudinally to plaster each part of the arc surface of the mold in turn. At the same time, the lifting structure 31 will continue to drive the plastering structure 32 to move up and down to adjust the up and down and upward position of the plastering structure 32 so that the plastering structure 32 can always fit the arc surface of the mold. Such a setting can reduce the labor intensity of workers, and adjust the up and down position of the plastering structure 32 through the lifting structure 31 to ensure that the plastering force of the plastering structure 32 on each part of the pipe segment surface is uniform, thereby ensuring the smoothness of the pipe segment surface and improving the plastering quality.

[0042] It should be noted that, in the embodiment of the utility model, the automatic plastering equipment 100 also includes a storage device, the storage device is electrically connected to the moving part 22, the lifting structure 31, and the plastering structure 32, and the storage device stores a variety of pipe segment mold models. After the moving part 22 drives the plastering mechanism 3 to move longitudinally to the top of the plastering station, the operator only needs to select the corresponding pipe segment mold model in the storage device and transmit the model data to the moving part 22, the lifting structure 31, and the plastering structure 32. Each structure can automatically adjust the longitudinal and upward position of the plastering structure 32 according to the data of the corresponding pipe segment mold model, thereby ensuring the plastering quality. In this way, the work intensity of the operator can be further reduced, and at the same time, it can also avoid the phenomenon of uneven plastering force due to operator error, and can ensure the plastering quality of the automatic plastering equipment 100.

[0043] Furthermore, the plastering structure 32 includes a mounting seat 321 and a roller 323. The mounting seat 321 is disposed at the lower end of the lifting structure 31. The mounting seat 321 is bent downward along both sides of the horizontal direction to form two bending portions 322. The roller 323 extends in the horizontal direction, and the two ends are rotatably connected to the two bending portions 322, respectively. The roller 323 can rotate along the axis extending in the horizontal direction. The mounting seat 321 can provide sufficient support force for the roller 323. When the plastering structure 32 performs plastering work, the plastering structure 32 also includes a rotating motor, which drives the roller 323 to rotate along the axis extending in the horizontal direction. The outer surface of the roller 323 rubs against the outer surface of the pipe segment, and the excess concrete on the outer surface of the pipe segment is consumed by the friction of the roller 323, thereby making the outer surface of the pipe segment smooth and flat.

[0044] It can be understood that by arranging the roller 323 to rotate along the transversely extending axis to contact the outer surface of the pipe segment and perform the plastering, the speed of clearing excess concrete from the outer surface of the pipe segment can be increased, thereby greatly improving the efficiency of the plastering work.

[0045] At the same time, the utility model does not limit the roughness of the outer surface of the roller 323. For example, the outer surface of the roller 323 can be concave and convex, and such a setting can further improve the speed of the roller 323 in removing excess concrete on the pipe segment; or, the outer surface of the roller 323 can also be smooth, so that the roller 323 can perform more delicate plastering work, thereby improving the smoothness of the outer surface of the pipe segment, and the operator can make a choice according to the actual situation.

[0046] Of course, when the outer surface of the drum 323 is concave-convex, the present invention also does not limit the pattern type of the outer surface of the drum 323.

[0047] Furthermore, in order to avoid the phenomenon that the roller 323 hits the mold and the pipe segment when the lifting structure 31 drives the plastering structure 32 to move in the up-down direction due to the equipment accuracy problem, the mounting seat 321 is connected to the lifting structure 31 through an elastic connector. With such a configuration, when the lifting structure 31 drives the mounting seat 321 and the roller 323 to move in the up-down direction, if the travel of the mounting seat 321 and the roller 323 moving in the up-down direction is greater than the distance between the roller 323 and the mold and the pipe segment, the elastic connector will be squeezed to avoid the roller 323 hitting the mold and / or the pipe segment, thereby causing damage to the equipment or the mold or the product, thereby improving the compatibility and safety of the automatic plastering equipment 100.

[0048] It should be noted that the automatic wiping device 100 further includes a limiting member, which can limit the elongation of the elastic connecting member to prevent the weight of the mounting seat 321 and the roller 323 from stretching the elastic connecting member.

[0049] In one embodiment, the limiting member includes a telescopic rod, which is arranged to avoid the elastic connecting member and connects the mounting seat 321 and the lifting structure 31. The telescopic rod has a maximum telescopic stroke. When the roller 323 does not abut the mold and / or the pipe segment, the telescopic rod has a main connecting function to prevent the weight of the mounting seat 321 and the roller 323 from stretching the elastic connecting member for a long time to affect the elastic modulus of the elastic connecting member. When the roller 323 abuts the mold and / or the pipe segment, the telescopic rod is also telescopic and will not affect the normal operation of the elastic connecting member. At the same time, the arrangement of the telescopic rod can also limit the position displacement of the mounting seat 321 and the roller 323 when the moving part 22 drives the plastering mechanism 3 to move longitudinally, thereby ensuring the stability of the automatic plastering equipment 100.

[0050] It should be noted that the limiting member can also be configured as a connecting rope or other structure that can limit the elongation of the elastic connecting member, and the present invention does not impose any limitation on this.

[0051] In order to clarify the pressure when the roller 323 abuts against the mold and / or the pipe segment, and to stop the lifting structure 31 in time when the pressure is too high, the automatic plastering device 100 also includes a pressure sensor, which is arranged on one side of the elastic connector to detect the pressure between the mounting seat 321 and the lifting device. When the elastic connector is squeezed, the pressure on the pressure sensor will increase. When the pressure on the pressure sensor increases to a preset value, the lifting structure 31 is stopped in time to avoid damage to the equipment, mold or product, and further ensure the safety of the automatic plastering device 100.

[0052] Specifically, the lifting structure 31 includes a plurality of mounting parts 311 and a plurality of telescopic parts 312. The plurality of mounting parts 311 are arranged on the moving part 22 at intervals in the horizontal direction. The plurality of telescopic parts 312 are respectively arranged on the corresponding mounting parts 311 and can move in the up-down direction. The lower ends of the plurality of telescopic parts 312 are commonly connected to the plastering structure 32. The mounting part is provided to ensure the stability of the connection with the moving part 22. The plurality of telescopic parts 312 can drive the plastering structure 32 to move in the up-down direction, so that the plastering structure 32 can abut against the mold and / or the pipe segment.

[0053] In addition, the installation portion and the telescopic portion 312 are provided in plurality, which can jointly restrict the plastering structure 32 and prevent the plastering structure 32 from rotating along the axis extending in the vertical direction, thereby ensuring the quality of the plastering work.

[0054] In order to make the lifting structure 31 have better moving accuracy, each of the mounting parts 311 includes a first motor and a first gear. The first motor is arranged on the moving part 22. The first gear rotates coaxially with the main shaft of the first motor. One end of each telescopic part 312 is arranged in a tooth shape to mesh with the first gear. Through the meshing of the first gear and the end face of the telescopic part 312 arranged in a tooth shape, the first motor works, the first motor drives the first gear to rotate, and then drives the telescopic part 312 to move in the up and down direction. Such a setting can ensure the moving accuracy of the telescopic part 312 in the up and down direction.

[0055] Furthermore, the base 1 includes two brackets 11 arranged at intervals in the transverse direction, the fixing portion 21 is provided on the two brackets 11, and the movable portion 22 is always located between the two brackets 11. With such a configuration, the plastering station is located between the two brackets 11, which can prevent the two brackets 11 from interfering with the normal operation of the automatic plastering device 100, thereby ensuring the stability of the operation of the automatic plastering device 100.

[0056] At the same time, when the base 1 is configured as two brackets 11 spaced apart in the transverse direction, the number of the fixed parts 21 can be configured as one or two. When the fixed part 21 is configured as one, the two ends of the fixed part 21 in the transverse direction are fixedly connected to the two brackets 11, and the movable part 22 is installed at the lower end of the fixed part 21 and moves between the two brackets 11 in the longitudinal direction; when the fixed part 21 is configured as two, the two fixed parts 21 are respectively installed on the two brackets 11, and the movable part 22 is arranged between the two fixed parts 21, and the two ends in the transverse direction are respectively connected to the two fixed parts 21, and the movable part 22 can move in the longitudinal direction. In summary, the number of the fixed parts 21 will not affect the movement of the movable part 22 in the longitudinal direction, and will not affect the normal operation of the wiping mechanism 3. Therefore, the number of the fixed parts 21 can be selected according to actual conditions.

[0057] Furthermore, the fixed part 21 includes two rails 211, each of which is provided on the upper end surface of the corresponding bracket 11 and extends in the longitudinal direction, and the movable part 22 includes a crossbeam 221, and the two ends of the crossbeam 221 in the transverse direction are respectively overlapped on the upper end surfaces of the two rails 211, and can slide along the two rails 211. Overlapping the crossbeam 221 on the two rails 211 can ensure the stability of the connection between the crossbeam 221 and the two rails 211, thereby ensuring the stability of the operation of the automatic wiping device 100.

[0058] Specifically, the automatic plastering device 100 further includes a driving structure, which includes a second motor, a second gear, and a rack. The second motor is mounted on the crossbeam 221, and the rack is longitudinally extended and arranged on the upper end surface of the track 211. The gear is fixed to the main shaft of the motor to rotate coaxially with the second motor, and the second gear is meshed with the rack. Such a setting enables the crossbeam 221 to move normally on the two tracks 211. At the same time, since the crossbeam 221 and the plastering mechanism 3 are heavy, the walking structure with gears and racks meshing can improve the longitudinal movement accuracy of the crossbeam 221.

[0059] In order to enable the automatic plastering device 100 to start plastering work after the mold moves to the plastering station, and further avoid mutual interference between the automatic plastering device 100 and the mold, the automatic plastering device 100 also includes a sensing device, which is arranged on the base 1 and electrically connected to the moving part 22, and the sensing device is used to detect the position of the mold. In this way, when the sensing device detects that the mold moves to the plastering station, it sends an electrical signal to the moving part 22 to allow the moving part 22 to move. At this time, the moving part 22 drives the plastering mechanism 3 to move longitudinally to the top of the plastering station to perform plastering work; when the sensing device does not send an electrical signal to the moving part 22, the moving part 22 cannot move, so as to further improve the safety of the automatic plastering device 100.

[0060] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
