Description

Technical Field

[0001] The utility model relates to an anti-collision limiting structure for a discharging station of conveying equipment, belonging to the technical field of material conveying equipment. Background Art

[0002] After the bags are stacked on the pallet, the sides of the pallet rest on two synchronously advancing conveyor chains. The pallet moves along with the conveyor chains to the unloading station, where it awaits removal by a forklift. The forklift's shovel arm must first be accurately inserted into the gap between the top and bottom surfaces of the pallet. The forklift then advances a distance to allow the shovel arm to penetrate to a sufficient depth. The shovel arm then rises, lifting the pallet and the bags above it, off the conveyor equipment for transfer.

[0003] During the above operations, due to unclear vision or incorrect operation of the forklift driver, it is easy for the forklift to get too close to the conveying equipment or even damage the conveying equipment. The current equipment safety protection measures mainly rely on wheel chocks, usually fixed angle steel on the ground as wheel chocks. This traditional protection method has obvious limitations:

[0004] 1. Because the angle steel is fixed to the ground, the forklift driver cannot directly observe it and find it difficult to judge the distance between the front tire and the angle steel. In addition, due to the heavy weight of the forklift, the forward impact force is very large, while the fixing force between the angle steel and the bottom surface is limited, which can easily cause the wheel chock to shift. Therefore, relying on the wheel chock to limit the position, the conveying equipment is still often damaged.

[0005] 2. The height of the angle steel is limited. If the forklift does not slow down in advance, the tire may still go over the wheel chock, directly causing a collision with the equipment;

[0006] 3. The limit of angle steel may cause certain damage to the tires of forklift;

[0007] 4. Even if the wheel chocks are reliably limited, it is difficult for the forklift driver to align the shovel arm with the empty space on the pallet because he has to observe both the left and right position and the height of the shovel arm. Once a mistake occurs, the pallet will be hit. At the very least, the pallet will be displaced and unable to be shoveled, and the packaging bags on it will be scattered. At the moderate level, the pallet will lose support on one side, causing the stacked packaging bags to overturn as a whole. At the worst, the conveyor chain of the conveying equipment will be directly damaged. All of the above will cause production line shutdown losses. Utility Model Content

[0008] The purpose of the utility model is to overcome the problems existing in the prior art and provide an anti-collision limit structure for the unloading station of a conveying equipment. The structure is simple and can effectively prevent the forklift from hitting the protective device and causing it to shift, thereby preventing the stacking from overturning or damaging the equipment.

[0009] The lifting mechanism comprises the following steps: first, a lifting mechanism is installed on the lifting platform, and second, a lifting mechanism is installed on the lifting platform to lift the lifting truck, and the lifting mechanism is installed on the lifting platform to lift the lifting truck.

[0010] Furthermore, a plurality of mounting holes are provided in the height direction of the vertical side of the shovel arm limiting L-shaped steel.

[0011] Furthermore, the bottom plate and the limit baffle are integral plates bent into an L-shape.

[0012] Furthermore, a plurality of reinforcing ribs are welded on the back side of the limit baffle.

[0013] The beneficial effects of the utility model are as follows: 1. The anti-collision limit structure is simple and reliable, easy to manufacture and low in cost; when the forklift is taking off, the wheel presses on the bottom plate, on the one hand, prompting the forklift driver to slow down, and stops when the front side of the wheel approaches the limit baffle; even if the wheel hits the limit baffle at a certain speed, since the limit baffle is connected to the bottom plate as a whole and the bottom plate is pressed by the wheel, the fixing bolts of the bottom plate will not be sheared, thereby avoiding the phenomenon that the forklift hits the protective device and causes it to shift.

[0014] 2. The bottom of the forklift's shovel arm can be close to the shovel arm limit L-shaped steel or fall on the shovel arm limit L-shaped steel. Move along the shovel arm limit L-shaped steel to insert it into the gap of the pallet, so as to avoid the shovel arm hitting the pallet or conveyor due to incorrect observation by the driver.

[0015] 3. The shovel arm limit L-shaped steel has multiple sets of mounting holes, and the height can be adjusted at any time to adapt it to the height of pallets of different specifications; a nylon pad is installed in front of the baffle to play a certain anti-collision role, and the pad is fixed by bolts and is easy to disassemble and replace.

[0024] In the following description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device must have a specific direction.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] like Figures 1 to 6As shown, the anti-collision limit structure of the unloading station of the conveying equipment of the present invention includes a base plate 4, and the base plate 4 is welded with an upwardly erected limit baffle 5 near the front of the conveying equipment 1, or the base plate 4 and the limit baffle 5 are an integral plate bent into an L shape. The width of the base plate 4 and the limit baffle 5 is greater than the width of the unloading forklift, and the position of the limit baffle 5 corresponds to the front extreme position of the front tire of the unloading forklift. The base plate 4 is fixed to the ground by expansion bolts or buried reinforcement, and when the base plate 4 is removed, it is pressed under the front tire of the unloading forklift. The two sides of the limit baffle 5 are respectively welded to the two sides of the base plate 4 by triangular reinforcement plates 6; the back of the limit baffle 5 is welded with multiple reinforcing ribs 7, which are especially arranged at the position corresponding to the forklift tire, and can extend vertically or horizontally or be arranged in a crisscross pattern.

[0028] The packaging bags 3 are stacked on the pallet 2. Conveyor chains are provided on both sides of the conveying equipment 1 in the width direction. The bottom of the pallet 2 is placed on the conveyor chains. The conveyor chains on both sides run synchronously to carry the pallet 2 and the packaging bags 3 thereon forward until they reach the unloading station and stop, waiting to be picked up by a forklift.

[0029] Since the bottom plate 4 has a large area, when the forklift's wheels first press against the bottom plate 4, the driver immediately decelerates, and the wheels have already pressed the bottom plate 4 tightly. Then the wheels continue to move forward a short distance, so that the front side of the wheels approaches or abuts against the limit baffle 5. Even if the wheels hit the limit baffle 5, since the bottom plate 4 is pressed by the wheels, the impact is an internal force and will not shear the fixing bolts of the bottom plate 4 or the buried reinforcement.

[0030] A shovel arm limiting L-shaped steel 8 is provided on the upper part of the limit baffle 5, and a nylon pad 9 is pressed on the outer side of the vertical edge of the shovel arm limiting L-shaped steel 8 facing the forklift. The nylon pad 9 and the shovel arm limiting L-shaped steel 8 are fixed to the upper part of the limit baffle 5 together by bolts 10; the horizontal edge of the shovel arm limiting L-shaped steel 8 extends in the direction of the conveying equipment 1, and the top height of the horizontal edge of the shovel arm limiting L-shaped steel 8 matches the idle height of the pallet 2 on the conveying equipment 1.

[0031] The driver can first raise the shovel arm of the forklift, then drop it above the shovel arm limit L-shaped steel 8, and then slowly move forward. The shovel arm of the forklift slides along the top edge of the shovel arm limit L-shaped steel 8, so that it is inserted into the gap of the pallet 2, avoiding the end of the shovel arm accidentally hitting the pallet 2 and causing overturning.

[0032] The vertical side height direction of the shovel arm limiting L-shaped steel 8 is provided with multiple groups of mounting holes, and the top height of the shovel arm limiting L-shaped steel 8 can be adjusted according to the specifications of the pallet 2 and the clearance height of the idle space.

[0033] The above description is only a preferred embodiment of the present invention, which shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It does not limit the scope of patent protection of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. In addition to the above embodiments, the present invention may have other implementation methods without departing from the spirit and scope of the present invention. The present invention may also have various changes and improvements. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the attached claims and their equivalents. The technical features not described in the present invention can be achieved by or using existing technologies, and will not be described here.
