Description

Technical Field

[0001] The utility model relates to the technical field of concrete sweeping, in particular to a sweeping mechanism. Background Art

[0002] Sweeping mechanisms are often used in the field of polishing to polish and grind the surface of an object to make it smoother. In the process of using concrete to make a hollow cylinder, the inner wall of the concrete cylinder can be cleaned by a sweeping brush that can rotate through the sweeping mechanism. Connecting a rotary motor is a common means to achieve the rotation of the sweeping brush. Since the cleaning width of the sweeping brush is much smaller than the depth of the concrete cylinder, the rotatable sweeping brush usually needs to be connected to a hydraulic cylinder that can move up and down in a cycle. However, after the existing hydraulic cylinder is connected to the rotary motor, the piston shaft will rotate with the rotary motor. During the cleaning process, after the brush end encounters resistance, the rotary motor will drive the piston shaft at the other end (under reaction force) to rotate, resulting in weak rotation stability of the sweeping mechanism and poor cleaning effect. Therefore, it is necessary to design a sweeping mechanism that can work up and down while also rotating. Utility Model Content

[0008] Furthermore, there are two symmetrically arranged sweeping brushes, and the brush surfaces of the sweeping brushes are oriented perpendicular to the axial direction of the directional cylinder and the rotating member.

[0009] Furthermore, the directional oil cylinder includes a cylinder barrel and a piston rod, a limit column with a non-circular cross-section is installed in the cylinder barrel along the axis, an inner hole is opened inside the piston rod along the axis, and the piston rod slides with the limit column through the inner hole to limit the rotation of the piston rod to achieve directional extension and retraction.

[0010] Furthermore, a limiting sleeve is provided in the inner hole, the inner wall of the limiting sleeve matches the shape of the outer wall of the limiting column, and the inner hole is slidably sleeved on the outer wall of the limiting column through the limiting sleeve.

[0025] Working principle: the rotating shaft of the rotating part 2 and the output shaft of the piston rod 101 are in the same straight line, and during the cleaning process, the piston rod 101 of the directional oil cylinder 1 will not rotate along with the rotating part 2, so that the rotating part 2 will not drive the piston rod 101 to rotate under the reaction force. The rotating part 2 has good rotational stability, and the cleaning and repairing effect of the inner wall of the concrete cylinder is better.

[0026] Preferably, the rotating part 2 is a rotating motor, and the rotating part 2 is connected to the piston rod 101 of the directional cylinder through a connecting box 5. The rotating motor can be detachably connected to the connecting box 5 by bolts, and the connecting box 5 can be detachably connected to the directional cylinder 1 by bolts. The connecting box 5 can not only detachably connect the rotating motor and the directional cylinder 1 respectively, but also can be used to place and protect the rotating motor. The outer wall of the connecting box 5 should have a certain anti-collision strength, and can be made of but not limited to stainless steel.

[0027] Preferably, a sprayer 4 is also installed at the output end of the rotating member, and the spray pipe of the sprayer 4 extends to the brush surface of the sweeping brush 3. The sprayer 4 is connected to the functional filler feeding box through a pipeline, and is used to repair the uneven pores in the concrete.

[0028] Preferably, there are two symmetrically arranged sweeping brushes 3, and the brush surfaces of the sweeping brushes 3 are oriented perpendicular to the axial direction of the directional cylinder 1 and the rotating member 2, so that the sweeping brushes 3 can clean or repair the inner wall of the concrete cylinder.

[0030] Preferably, a limit sleeve 104 is provided in the inner hole, and the inner wall of the limit sleeve 104 matches the shape of the outer wall of the limit column 103. The inner hole is slidably sleeved on the outer wall of the limit column 103 through the limit sleeve. The inner wall of the limit sleeve 104 matches the shape of the outer wall of the limit column 103 so that there is good sealing between the two, so that the medium oil can provide sufficient thrust during the sliding process of the piston rod 101 and the oil in the inner hole of the piston rod 101 will not be too much to affect the normal linear motion speed of the piston rod 101.

[0031] Preferably, the non-circular shape refers to one of a triangle, a square, a regular pentagon, a regular hexagon, a regular octagon, a rhombus, an ellipse or a semicircle. The limit column 103 can be but is not limited to being set to a limit column 103 of the above shape, which can prevent the piston rod 101 mounted on the outer wall from rotating.

[0033] Preferably, the lower end of the piston rod 101 is connected to a piston 107, and the piston 107 is intercepted and arranged in the cylinder 102, and an annular sealing ring 108 is filled between the piston 107 and the cylinder 102. The piston 107 and the lower end cylinder 102 form an oil inlet space for oil intake, and have good sealing performance. The annular sealing ring 108 can be made of but not limited to high temperature resistant rubber, which can not only further enhance the sealing performance between the piston 107 and the cylinder 102, but also adapt to the situation where the medium oil temperature in the cylinder is higher.

[0034] Preferably, an induction magnetic ring 109 for detecting the position of the piston rod 101 in the cylinder is provided in the cylinder barrel 102. The induction magnetic ring 109 can detect the position of the piston rod 101 in the cylinder by means of the Hall effect. Conventional settings such as a magnetic switch need to be installed outside the cylinder. Preferably, a limiter capable of limiting the sliding distance of the piston rod 101 is installed to prevent the piston rod 101 from detaching from the limit column 103.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
