Description

Technical Field

[0001] The utility model relates to the technical field of slurry brushing, in particular to a cement pipe slurry brushing device. Background Art

[0002] The surface of the manufactured cement components has different degrees of roughness such as pores, depressions or rough surfaces, which affect the use, service life and aesthetics. In order to solve this technical problem, manufacturers currently need to brush slurry on the surface of the cement components after they are formed.

[0003] Existing slurry brushing technology often uses a slurry brushing device for making cement pipes, such as the one disclosed in announcement number CN214520910U. The cement pipe is placed vertically in an annular groove, and then the inner brush head is adjusted to brush the inner wall of the cement pipe, and then the outer brush head is adjusted to brush the outer wall of the cement pipe. The inner and outer brush heads are driven by a motor to brush the cement pipe at the same time. The cement pipe itself has the characteristics of high height and heavy weight. The cement pipe is placed in the annular groove for fixing. During the slurry brushing operation, the cement pipe is prone to tilt and fall to the ground, posing a major safety hazard. It will not only damage the device itself, but also affect the personal safety of the staff. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A cement pipe slurry brushing device includes a workbench 1, which is composed of a hollow base 101, three circumferentially equidistantly distributed support columns 102 and a top cover 103 connected in sequence from bottom to top, and a load-bearing plate 2 is horizontally arranged in the hollow base 101, and the hollow base 101 and the top cover 103 are connected by three support columns 102, providing sufficient space for the workbench 1 to facilitate the placement of the cement pipe, and a load-bearing plate 2 is welded at the bottom end of the workbench 1.

[0023] A driving motor 3 is fixed to the upper end of the load-bearing plate 2, and a fixing mechanism for limiting the cement pipe is provided on the workbench 1 through the driving motor 3. Figure 2 :

[0024] First, the fixing mechanism includes a driving gear 8 fixedly connected to the output end of the driving motor 3, and two transmission racks 9 meshing with the driving gear 8 are slidably installed at the bottom of the workbench 1. The two transmission racks 9 are centrally symmetrically arranged on both sides of the driving gear 8. The free ends of the two transmission racks 9 are welded with clamps 10 that touch the outer wall of the cement pipe from the outside to the inside, and the clamps 10 slide through the hollow base 101. The driving gear 8 rotates clockwise to drive the transmission racks 9 to move toward each other, and fix them from the outer wall of the cement pipe;

[0025] Secondly, the fixing mechanism also includes a guide column 12 which is integrally welded to the workbench 1 and has four long guide holes 13. The four long guide holes 13 are equidistantly distributed on the guide column 12. A ball screw 11 driven to rotate by the drive motor 3 is rotatably installed between the workbench 1 and the guide column 12. A sliding nut 14 threadedly connected to the ball screw 11 is slidably installed in the guide column 12. Four guide rods 15 corresponding to the long guide holes 13 are rotatably installed on the sliding nut 14. The guide rods 15 slide through the long guide holes 13. The free ends of the four groups of guide rods 15 are all rotatable. A support plate 7 is connected that contacts the inner wall of the cement pipe from the inside to the outside, and four support plates 7 are slidably installed on the hollow base 101. The ball screw 11 rotates to drive the nut to move downward, and the support plate 7 is pulled by the guide rod 15. The four support plates 7 spread outward at the same time and are fixed from the inner wall of the cement board. At the same time, the four support plates 7 are equidistantly distributed in the circumferential direction, and the support plates 7 are L-shaped structures. The driving motor 3 controls the movement of the clamping plate 10 and the support plates 7 at the same time, and clamps and fixes the cement pipe from the inner and outer walls to ensure that the cement pipe is stably placed on the hollow base 101 during the slurry brushing process.

[0026] A lifting rod 4 is fixedly installed on the upper end of the workbench 1, and a load-bearing plate 5 is welded on the output end of the lifting rod 4. A brush head 6 for brushing slurry on the inner and outer walls of the cement pipe is installed at the bottom end of the load-bearing plate 5. The brush head 6 is divided into one at the center position and two symmetrically arranged at the outer position to facilitate synchronous spraying of the inside and outside of the cement pipe.

[0027] It should be noted that the specific models and specifications of the drive motor 3 and the lifting rod 4 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Place the cement pipe on the hollow base 101 and turn on the drive motor 3. At this time, the drive gear 8 rotates clockwise to drive the clamping plate 10 to move towards each other on the hollow base 101, clamping and fixing the outer wall of the cement pipe from the outside to the inside;

[0030] At the same time, the ball screw 11 rotates to drive the sliding nut 14 to move downward in the guide column 12. At this time, the guide rod 15 is pulled to drive the support plate 7 to slide on the hollow base 101, supporting and fixing the inner wall of the cement pipe from the inside to the outside;

[0031] The lifting rod 4 is controlled to extend downward until the load-bearing plate 5 is in contact with the top of the cement board, and the brush head 6 is turned on to paint the inner and outer walls of the cement pipe.
