Description

Technical Field

[0001] The invention relates to the technical field of caster assemblies, and in particular to a caster assembly for a high-pressure cleaning machine. Background Art

[0002] The main function of the caster assembly for the high-pressure cleaner is to move and fix it. The caster assembly can be used to move the high-pressure cleaner from different locations, such as from a laboratory to a workshop, or move it within a workshop, thereby facilitating the use of the equipment in different scenarios; the caster assembly can also help the high-pressure cleaner to be stably fixed in a certain position, which can effectively prevent the equipment from shaking or moving during work.

[0003] However, the existing high-pressure cleaning machines will vibrate continuously when working. In the long run, the caster assembly at the bottom of the high-pressure cleaning machine is easily worn, thereby affecting the subsequent stability of the caster assembly. At the same time, when the high-pressure cleaning machine is working, a large amount of water and detergent are needed to clean the items. This causes water and detergent to easily fall on the indoor floor during operation. When the caster assembly subsequently drives the high-pressure cleaning machine to move, the water and detergent may be splashed onto the brake pads. At the same time, the anti-skid patterns on the outside of the casters will also adhere to dust and debris due to the influence of water and detergent. These will affect the subsequent normal braking and movement of the caster assembly, and the existing caster assembly braking method may not be stable and fast enough to achieve a good braking effect.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, the rotating ring is pressed downward, and the rotating ring drives the fixed rod and the movable seat connected to the two ends of the fixed rod to move downward, so that the clamping block arranged on the upper end surface of the movable seat moves out of the clamping hole opened on the upper side of the slide groove, and then the rotating ring is rotated to drive the irregular wiper blade to rotate toward one side of the tire, and at the same time, the irregular wiper blade is pressed down to the ground, and then the rotating ring is rotated again to drive the irregular wiper blade to scrape the accumulated water, cleaning agent and debris on the ground to the outside, so as to prevent the accumulated water, cleaning agent and debris from affecting the support and shock absorption effect of the subsequent support seat and shock absorbing pad, and then the rotating ring is stopped and pulled to drive the two movable seats to move upward to the upper end of the movable seat.

The four motors are started, and the motor drives the first shaft to rotate, and the first shaft drives the first gear to rotate, and the first gear drives the second gear meshing at the extension to rotate, so that the first shaft and the second shaft respectively drive the two bases and the two brake pads arranged on one side of the two bases to press against the outside of the tire respectively. The setting of the two-way brake pads is more conducive to fast and stable braking operations on the outside of the tire.

[0017] 3. The cleaning and shock-absorbing mechanism provided in the present invention can not only effectively scrape outwards the water, cleaning agent and debris on the ground where the shock-absorbing pad is pressed down, to prevent the accumulation of water, cleaning agent and debris from affecting the support and shock-absorbing effect of the subsequent support seat and the shock-absorbing pad, but also the two inclined rotating rods and the shock-absorbing pad horizontally fitted to the ground can effectively reduce the wear of the caster mechanism below when the subsequent cleaning machine vibrates during operation, and provide additional support force and stability; the brake cleaning mechanism effectively reduces the splashing of water and cleaning agent on the ground onto the brake pad during the movement of the tire, and can also effectively clean the dirt adhered to the inner side of the anti-skid pattern provided on the outer side of the tire during the movement, which is conducive to better subsequent braking operations, and the setting of the two-way brake pad is more conducive to fast and stable braking operations on the outer side of the tire.

When the motor 23 is started, the motor 23 drives the first shaft 18 to rotate, and the first shaft 18 drives the first gear 21 to rotate, and the first gear 21 drives the second gear 22 meshed at the outer extension to rotate, so that the first shaft 18 and the second shaft 19 respectively drive the two bases 6 and the two brake pads 20 arranged on one side of the two bases 6 to press against the outer side of the tire 5, thereby quickly and effectively braking the tire 5.

[0030] Two fixing plates 25 are fixedly installed on both sides of the upper end of the mounting frame 17, and the upper ends of the two fixing plates 25 are slidably connected with the rotating grooves 26 opened on the lower surface of the rotating seat 1, and two protective boxes 7 are fixedly installed on both sides of the rim 42 and at the bottom ends of the two bases 6.

At the same time, the bristles 28 arranged on the inner side of the protective box 7 during the movement of the tire 5 can also effectively clean the dirt on the outer pattern of the tire 5, which is conducive to better subsequent braking operations.

[0031] like Figure 5 and Figure 6As shown, a cleaning and damping mechanism is arranged on one side of the lower surface of the two connecting plates 3, and the cleaning and damping mechanism includes a rotating damping pad 8 and an irregular wiper plate 9. Two sets of mounting plates 29 are fixedly connected at both ends of the lower surface of the two connecting plates 3, and the bottom sides of the two mounting plates 29 at the two most side positions are fixedly connected with curved support plates 35. Slide grooves 36 are respectively provided inside the two curved support plates 35 and close to one side. A moving seat 37 is slidably installed inside the slide groove 36. The inner side of the two moving seats 37 is The side is rotatably connected with a fixing rod 38, the bottom side of the fixing rod 38 is fixedly connected to the upper end of the irregular wiper blade 9, the bottom end of the irregular wiper blade 9 is fixedly sleeved with a rubber sleeve, the middle of the fixing rod 38 is fixedly sleeved with a rotating ring 39, the upper end surface of the movable seat 37 is fixedly installed with a clamping block 40, the upper end of the clamping block 40 is clamped with a clamping hole 41 opened on the upper side of the slide groove 36, the inner sides of the two mounting plates 29 of each group are respectively rotatably matched with the two ends of the mounting shaft 30, and the outer surfaces of the mounting shafts 30 on both sides are respectively threaded sleeves The second nut 31 is provided, and a resistance rubber ring is provided at the rotation connection between the mounting shaft 30 and the mounting plate 29. A connecting block 32 is fixedly installed in the middle of the outer surface of the mounting shaft 30, and the bottom end of the connecting block 32 is fixedly connected to a rotating rod 33, and the bottom ends of the two rotating rods 33 are fixedly connected to a supporting seat 34, and the bottom of the supporting seat 34 is fixedly connected to the upper surface of the shock-absorbing pad 8. After the rotating rod 33 horizontal to the ground is rotated downward until the supporting seat 34 connected to the bottom end of the rotating rod 33 and the shock-absorbing pad 8 installed at the bottom of the supporting seat 34 are close to the ground, the second nuts 31 provided on the outer surfaces of the two mounting shafts 30 are respectively rotated to lock and fix one end of the two mounting shafts 30 to one side of the two mounting plates 29. The two inclined rotating rods 33 and the shock-absorbing pad 8 horizontally fitted to the ground can effectively reduce the wear of the caster mechanism below when the subsequent cleaning machine 43 is vibrating during operation, and provide additional supporting force and stability. The outwardly inclined rotating rod 33 matches the anti-slip property of the cleaning machine 43 to a certain extent, which can effectively reduce the risk of sliding and rollover.

[0032] By pressing the rotating ring 39 downward, the rotating ring 39 drives the fixed rod 38 and the movable seat 37 connected at both ends of the fixed rod 38 to move downward, so that the clamping block 40 set on the upper end surface of the movable seat 37 moves out of the clamping hole 41 opened on the upper side of the slide groove 36, and then the rotating ring 39 is rotated to drive the irregular wiper blade 9 to rotate toward one side of the tire 5, while pressing the irregular wiper blade 9 down to the ground. After that, the rotating ring 39 is rotated again to drive the irregular wiper blade 9 to scrape the accumulated water, cleaning agent and debris on the ground to the outside, thereby preventing the accumulated water, cleaning agent and debris from affecting the support and shock absorption effect of the subsequent support seat 34 and the shock absorbing pad 8.

At the same time, the bristles 28 arranged on the inner side of the protective box 7 can also effectively clean the outer side of the tire 5 during the movement. The dirt on the pattern is cleaned to avoid affecting the subsequent braking effect. When the cleaning machine 43 stops moving, the four motors 23 are started at the same time. The motors 23 drive the first shaft 18 to rotate, and the first shaft 18 drives the first gear 21 to rotate. The first gear 21 drives the second gear 22 meshed at the extension to rotate, so that the first shaft 18 and the second shaft 19 respectively drive the two bases 6 and the two brake pads 20 set on one side of the two bases 6 to stick to the outside of the tire 5 respectively, so as to quickly and effectively brake the tire 5. After that, the rotating ring 39 is pressed downward, and the rotating ring 39 drives the fixed rod 38 and the movable seat 37 connected at both ends of the fixed rod 38 to move downward, so that After the clamping block 40 provided on the upper end surface of the movable seat 37 moves out of the clamping hole 41 opened on the upper side of the slide groove 36, the rotating ring 39 is rotated to drive the irregular wiper blade 9 to rotate toward one side of the tire 5, and at the same time, the irregular wiper blade 9 is pressed down to the ground. After that, the rotating ring 39 is rotated again to drive the irregular wiper blade 9 to scrape the accumulated water, cleaning agent and debris on the ground to the outside, thereby preventing the accumulated water, cleaning agent and debris from affecting the support and shock absorption effect of the subsequent support seat 34 and the shock absorbing pad 8. After that, the rotating ring 39 is stopped and pulled to the rotating ring 39, so that it drives the two movable seats 37 to move upward until the clamping block 40 provided on the upper end surface of the movable seat 37 is clamped again to the clamping hole 41 opened on the upper side of the slide groove 36. The locking hole 41 is formed in the center of the fixing hole 41. Finally, the rotating rod 33 horizontal to the ground is rotated downward until the support seat 34 connected to the bottom end of the rotating rod 33 and the shock-absorbing pad 8 installed at the bottom of the support seat 34 are close to the ground. Then, the second nuts 31 arranged on the outer surfaces of the two mounting shafts 30 are rotated respectively to lock and fix one end of the two mounting shafts 30 on one side of the two mounting plates 29. The two inclined rotating rods 33 and the shock-absorbing pad 8 horizontally fitted to the ground can effectively reduce the wear of the caster mechanism below when the subsequent cleaning machine 43 vibrates during operation, and provide additional support force and stability. The outwardly inclined rotating rod 33 matches the anti-slip property of the cleaning machine 43 to a certain extent, and can effectively reduce the risk of sliding and rollover.
