Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, in particular to a mobile coating abrasive equipment. Background Art

[0002] During the coating processing, abrasive equipment, namely a grinding machine, is usually required. The main function of the grinding machine is to grind pigments, fillers or other additives into fine powders or particles to ensure the uniformity, stability and required texture characteristics of the coating.

[0003] At present, the existing grinding machines are all placed on a chassis with wheels to achieve the mobile function. The wheels of the chassis are universal wheels with foot brakes, and the braking is generally achieved through the foot brakes. However, the grinding machine is heavy, and during the moving process, due to its large inertia, the braking distance of the grinding machine is lengthened. When emergency braking is required, the brakes on the universal wheels cannot effectively brake the grinding machine with large inertia, which easily causes the grinding machine to collide with people or equipment, resulting in damage and safety accidents. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a mobile coating abrasive equipment, which is suitable for the effective braking of a grinding machine with large inertia and long braking distance.

It is characterized in that it further includes a braking mechanism, and the braking mechanism includes a brake box connected to the lower end of the chassis, a brake pad sliding up and down along the brake box, and a first driving member connected to the brake pad and driving the brake pad to descend to generate braking force or ascend to release the braking force.

[0006] In the above solution, by adding a brake pad and a first driving member for driving the brake pad to brake on the chassis, the effective braking of the grinding equipment is achieved through the action of the brake pad, avoiding collision with people or equipment and ensuring the safety of personnel and equipment.

[0007] Preferably, support seats are provided on both sides of the chassis. The first driving member has a fixed end and a movable end. The fixed end is connected to the support seat on one side, and the movable end is connected to the brake pad.

[0010] Preferably, a plurality of reinforcing blocks are connected between the brake box and the chassis, and the plurality of reinforcing blocks are arranged at intervals along the length of the brake box.

[0011] Preferably, the mobile coating abrasive equipment further includes a locking mechanism for locking the rising height of the brake pads. During the descending process of the brake pads, the locking mechanism disengages from the brake pads.

[0012] Preferably, a lock hole penetrating through one side wall of the brake box is provided on the brake pads. The locking mechanism includes a U-shaped block installed on the side wall of the brake box and corresponding to the position of the lock hole, a plug block adapted between the lock hole and the U-shaped block, and a second driving member for driving the plug block to move between the lock hole and the U-shaped block. The second driving member drives the plug block to act to form a first position and a second position. In the first position, the plug block is inserted into the lock hole, and the brake pads rise to a state of releasing the braking force. In the second position, the plug block disengages from the lock hole, and the brake pads descend to a state of generating the braking force.

The second connecting rope is connected to the upper end of the driving block. In the first position, the driving block descends to make the vertical surface contact with the side wall of the insertion hole, and the second spring resets. In the second position, the driving block rises to make the second inclined surface contact with the side wall of the insertion hole, and the second spring is compressed.

[0018] Second, when braking, the brake pads contact the ground, providing a larger contact area and a stronger braking force, thus stopping the grinding machine more quickly and avoiding dangerous accidents such as slow response and collisions when the braking distance is long.

[0019] Third, by manually controlling the second pinch rod to actuate the second connecting rope to release the position lock of the brake pads, and then driving the brake pads through the elastic force of the first spring to achieve the braking action, it can reduce the reaction time and distance of braking and improve the safety of operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will describe the present utility model in detail with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. For the sake of convenience of description, words such as "upper", "lower", "left", and "right" hereinafter only represent the same directions as the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure.

[0026] As Figure 1 shown, a mobile paint abrasive equipment provided in this embodiment includes a chassis 1, a grinding machine 2, a support seat 3, a brake mechanism 4 and a locking mechanism 5.

[0027] The bottom of the chassis 1 is provided with universal wheels 11, and support seats 3 are arranged on both sides of the chassis 1. The grinding machine 2 is placed on the chassis 1 and installed with the support seats 3 on both sides. The grinding machine 2 is used for grinding coatings. A control circuit, a circuit board, control buttons, etc. for controlling the operation of the grinding machine 2 are arranged in one of the support seats 3, and the height of this support seat 3 is higher than that of the support seat 3 on the other side for installing the first handle 411 in the first driving member 41.

[0028] As Figure 1 、 Figure 2 shown, the braking mechanism 4 includes a first driving member 41, a brake box 42, a brake pad 43, a first support block 44, and a reinforcement block 45. The first driving member 41 includes a first handle 411, a first pinch rod 412, a first connecting rope 413, and a first spring 414. The first handle 411 is fixed on the support seat 3 on one side, and the first pinch rod 412 is hinged to the first handle 411. One end of the first connecting rope 413 is connected to the first pinch rod 412, and the other end of the first connecting rope 413 passes through the first support block 44 on the support seat 3 and is connected to the brake pad 43 in the brake box 42.

[0029] As Figure 2 shown, the brake box 42 is a box-shaped structure with an open lower end, and a brake pad 43 that can move up and down is arranged inside it. The brake pad 43 includes a connecting block 431 and a braking block 432, and the braking block 432 is a wear-resistant rubber sheet. The first connecting rope 413 passes through a through hole opened at the top of the brake box 42 and is connected to the connecting block 431 of the brake pad 43. A first spring 414 is sleeved on the first connecting rope 413, and the first spring 414 abuts between the inner top surface of the brake box 42 and the connecting block 431. A lock hole 433 penetrating one side wall of the brake box 42 is opened on one side of the connecting block 431, and a first inclined surface 4331 is provided below the lock hole 433.

[0030] As Figure 1 shown, the brake box 42 is fixed to the bottom of the chassis 1, and a plurality of reinforcement blocks 45 are connected between the brake box 42 and the chassis 1. The plurality of reinforcement blocks 45 are arranged at intervals along the length of the brake box 42 to play a strengthening role.

[0031] As Figure 2 、 Figure 3As shown, the locking mechanism 5 includes a second driving member 51, a second support block, a U-shaped block 52, and an insertion block 53. The second driving member 51 includes a second handle 511, a second pinch rod 512, a second connecting rope 513, a driving block 514, and a second spring 515. The second handle 511 and the first handle 411 are fixed to the same support base 3, and are arranged one on the left and the other on the right. The second pinch rod 512 is hinged to the second handle 511. One end of the second connecting rope 513 is connected to the second pinch rod 512, and the other end of the second connecting rope 513 passes through the second support block on the support base 3 and is connected to the driving block 514. The first support block 44 and the second support block are located at appropriate positions on the support base 3 to ensure smooth movement of the connecting ropes passing through them respectively.

[0032] As Figure 3 shown, one end of the insertion block 53 is provided with a through hole 531 that penetrates up and down, and the through hole 531 has a width W2. The outer surface of the other end of the insertion block 53 is provided with a first arc surface 532. The first arc surface 532 is adapted to the first inclined surface 4331 (as Figure 2 shown). One side of the driving block 514 is successively provided with a vertical surface 5141, a second inclined surface 5142, and a second arc surface 5143 from top to bottom, so that the width of the driving block 514 gradually increases from top to bottom, so that the width W1 of the driving block 514 provided with the second arc surface 5143 is the largest, and W1 > W2. The second arc surface 5143 forms a convex structure, which can abut against the lower surface of the insertion block 53 to prevent the driving block 514 from disengaging from the through hole 531 when moving upward. When the driving block 514 moves upward, the insertion block 53 is displaced in a direction away from the lock hole 433 through the second inclined surface 5142 with a gradually increasing width to achieve unlocking and form a second position.

[0033] As Figure 2 shown, one side of the opening of the U-shaped block 52 is fixed to the side wall of the brake box 42, and the lock hole 433 corresponds to the position of the U-shaped block 52. As Figure 3 shown, one end of the second spring 515 is fixed to the inner wall of the U-shaped block 52, and the other end abuts against the vertical surface 5141. When the external force is eliminated, the second spring 515 drives the insertion block 53 to extend into the lock hole 433 to achieve locking and lock the height of the brake pad 43.

[0034] When the mobile paint abrasive equipment is in use, the brake pad 43 rises and lifts off the ground. At this time, the second spring 515 is in the initial state, the insertion block 53 is inserted into the lock hole 433, and the vertical surface 5141 of the driving block 514 is placed in the through hole 531 to form a first position.

[0035] For emergency braking, press the second pinch lever 512 by hand, so that the second connecting rope 513 is pulled upward, and the driving block 514 is pulled upward. The second inclined surface 5142 gradually moves upward into the jack 531 and contacts the side wall of the jack 531 away from the first arc surface 532. As the second inclined surface 5142 continues to move upward, the plug block 53 is pushed out of the lock hole 433, and the second spring 515 is compressed to form the second position. When the plug block 53 completely disengages from the lock hole 433, the restraint force of the first spring 414 comes into contact, and it resets to push the brake pad 43 downward, so that the brake block 432 contacts the ground to achieve the braking state.

[0036] When it is necessary to release the brake and resume work, release the second pinch lever 512, press the first pinch lever 412 by hand, so that the first connecting rope 413 is pulled upward, and the brake pad 43 is pulled upward. When the lock hole 433 is aligned with the plug block 53, under the action of the second spring 515, the plug block 53 is pushed out and extends into the lock hole 433 to return to the first position again. To release the braking force state, release the first pinch lever 412.

[0037] The length of the second connecting rope 513 needs to be designed appropriately to prevent the driving block 514 from falling off at the jack 531 in the first position.

[0038] In other embodiments, a plurality of the first springs 414 can be arranged at intervals along the length of the brake box 42 to increase the braking force.

[0039] The first connecting rope 413 and the second connecting rope 513 are in a straightened state under normal conditions, and steel wires can be selected.

[0040] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
