Description

Technical Field

[0001] The utility model belongs to the technical field of hair cutting equipment, and in particular relates to a centrifugal automatic swing arm hair cutting device. Background Art

[0002] During the construction of bridges, when the anchor hole is sealed, a roughening device is used to roughen the inner wall of the anchor hole in order to improve the quality of the new concrete sealing in the later stage. The existing roughening device uses a motor to drive a rotating bracket to rotate, and a swing arm is hingedly provided on the rotating bracket. A roughening wheel is provided at the end of the swing arm. When the rotating bracket rotates, due to the effect of centrifugal force, the swing arm drives the roughening wheel to move outward to roughen the inner wall of the anchor hole. When the roughening work stops, the swing arm is retracted onto the rotating bracket. However, the retraction action of the swing arm is usually driven by a torsion spring, which is not convenient for realizing the automatic control of the swing arm and monitoring of the swing arm status. If the swing arm is in a state where it cannot be retracted on the rotating bracket, when the roughening device enters the inside of the channel, it is easy to cause damage to the entire equipment.

[0025] Compared with the prior art, the centrifugal automatic swing arm chiseling tool provided in this embodiment is provided with a mounting frame 1, on which a rotating frame 2 is rotatably provided, one end of the rotating frame 2 is rotatably provided on the mounting frame 1, and a swing arm 5 is hingedly provided at the other end of the rotating frame 2, and the number of the swing arms 5 is multiple, and the multiple swing arms 5 are evenly arranged on the rotating frame 2 along the circumference of the rotating frame 2. The driving member 3 is a hydraulic motor, the fixed end of the driving member 3 is fixedly installed on the mounting frame 1, the driving end of the driving member 3 is transmission-connected to the rotating frame 2, and a rotating shaft 4 is rotatably provided on the rotating frame 2, and the axis of the rotating shaft 4 is arranged parallel to the axis of the driving end of the driving member 3. A swing arm 5 is fixedly installed at one end of the rotating shaft 4, and the driving end of the swing cylinder 6 is transmission-connected to the other end of the rotating shaft 4. When the swing cylinder 6 is ventilated, the swing arm 5 swings toward the inside of the rotating frame 2. When the swing cylinder 6 is not ventilated, the driving end of the swing cylinder 6 and the swing arm 5 are in a free state, and can drive the chiseling roller 51 to chisel the inner wall of the anchor hole by centrifugal force when the rotating frame 2 rotates. In the later stage, the working state of the swing arm 5 can be determined by monitoring the working state of the swing cylinder 6, which is convenient for realizing automatic control and improving the safety of the later chiseling device during use.

[0026] Preferably, in this embodiment, a magnetic switch for monitoring the working state of the swing cylinder 6 is installed on the swing cylinder 6. The working state of the swing cylinder 6 can be monitored by the magnetic switch, thereby determining the position state of the swing arm 5, which is convenient for the later control of the chiseling device.

[0027] In some embodiments, the rotating frame 2 may be configured as follows: Figure 1 , Figure 2 See also Figure 1 , Figure 2 The rotating frame 2 is also fixedly mounted with a stopper 7 for limiting the swing arm 5 to rotate inside the rotating frame 2. When the swing arm 5 abuts against the stopper 7, the chiseling roller 51 on the swing arm 5 is in a retracted state. The stopper 7 is fixedly mounted on the rotating frame 2. When the swing cylinder 6 drives the swing arm 5 to rotate inside the rotating frame 2, and the swing arm 5 drives the chiseling roller 51 to be retracted onto the rotating frame 2, the middle part of the swing arm 5 abuts against the stopper 7, so that the swing arm 5 is stored. At the same time, the storage position is relatively fixed, which is convenient for monitoring the state of the swing cylinder 6 in the later stage.

[0028] In some embodiments, the rotating frame 2 may be configured as follows: Figure 1 See the structure shown. Figure 1The rotating frame 2 includes a first annular disk 21 and a second annular disk 22 which are arranged in parallel at intervals.

The first annular disk 21 and the second annular disk 22 are coaxially arranged. The swing cylinder 6 and the driving member 3 are both mounted on the second annular disk 22. The swing arm 5 is rotatably arranged on the side of the first annular disk 21 away from the second annular disk 22 through the rotating shaft 4. Multiple connecting columns 23 are evenly spaced and arranged between the first annular disk 21 and the second annular disk 22 along the circumference of the first annular disk 21. The structure is simple and can reduce the overall weight of the rotating frame 2.

[0029] In some embodiments, the rotating shaft 4 may be Figure 2 See the structure shown.

A mounting hole for mounting the bearings 41 is provided on the side opposite to the first annular disk 21 and the second annular disk 22. Both ends of the rotating shaft 4 are mounted inside the inner ring of the bearing 41, and a sleeve 42 is sleeved on the outer side of the rotating shaft 4, and both ends of the sleeve 42 are against the inner ring of the bearing 41, so as to limit the two bearings 41 inside the first annular disk 21 and the second annular disk 22.

[0030] Preferably, in this embodiment, an anti-rotation hole for connecting the driving end of the swing cylinder 6 is provided at one end of the rotating shaft 4, and the driving end of the swing cylinder 6 is inserted into the anti-rotation hole. The driving end of the swing cylinder 6 and the anti-rotation hole are both provided with corresponding anti-rotation edges.

When the swing arm 5 abuts against the stopper 7, the outer side of the swing arm 5 is located inside the outer side of the first annular disk 21 and is flush with the outer side of the first annular disk 21. Setting the outer side of the swing arm 5 to an arc-shaped structure that matches the outer side of the first annular disk 21 can more conveniently store the swing arm 5 flush with the outer side of the first annular disk 21 or inside the annular disk. Avoid partially protruding the swing arm 5 from the outer side of the first annular disk 21 and affecting the use of the haircutting tool.
