Description
Technical Field
[0001] The present invention relates to the technical field of pallet stacking auxiliary equipment, and more particularly to a pallet stacking device with improved stability. Background Art
[0002] The pallet stacker is an auxiliary equipment used to stack pallets neatly.
[0003] Reference to the container board in the prior art Figure 5 As shown, airport staff generally use a forklift to place several stacked pallets 4 directly on the ground.
[0004] The above-mentioned prior art solutions have the following defects: when airport staff stack pallets, the forklift can only neatly place the end faces of the pallets in the length direction through the limit treatment of the outer surface of the forklift, but some pallets do not have limit devices in the width direction, making it difficult to stack each pallet neatly. Once subjected to external force, the pallets at high places may be in danger of falling, so there is room for improvement. Summary of the invention
[0005] In view of the shortcomings of the prior art, an object of the present invention is to provide a pallet stacker with improved stability, which has the advantage of reducing the risk of pallets at high places falling due to disorderly stacking of pallets.
[0006] The above-mentioned object of the present invention is achieved through the following technical solutions:
[0007] A plate stacker with improved stability, comprising a bottom plate, a front frame and a plurality of support frames, wherein the front frame is arranged on a side wall at one end of the bottom plate in the length direction, the support frames are respectively arranged on the side walls at both sides of the bottom plate in the width direction, and the bottom plate is provided with a plurality of protrusions, which are all arranged along the length direction of the bottom plate;
[0008] A first fixing pin is inserted horizontally through the support frame, one end of the first fixing pin is threadedly connected to a first fixing nut, a flush rod is rotatably connected to the support frame, a flush tube is inserted through the flush rod, the flush tube is sleeved on the first fixing pin, the flush rod is located in the support frame, and the side wall of the flush rod is in contact with the side wall of the bottom plate;
[0009] The support frame is provided with a limiting round rod in a direction away from the bottom plate, and the flush rod can be rotated to abut against the limiting round rod.
[0010] By adopting the above technical scheme, when the pallet stacker is transported to the designated position, the flush rod is slightly tilted and then tilted away from the bottom plate under the action of gravity, and finally the flush rod is limited by the limiting round rod; at this time, the airport operator uses a forklift to place the pallet on the bottom plate, the fork of the forklift is located between adjacent protrusions, the pallet is placed on the protrusions, the fork of the forklift continues to descend, and there is a gap between the fork of the fork of the forklift and the pallet and the bottom plate, at this time, the fork of the forklift is pulled out; the airport operator rotates the flush rod in the direction close to the bottom plate, so that the side wall of the flush rod is in contact with the side wall of the bottom plate; at this time, several pallets are stacked neatly, reducing the risk of pallets at high places falling due to the messy stacking of pallets.
[0011] The present invention is further configured as follows: a second fixed pin is horizontally penetrated on the support frame, one end of the second fixed pin is threadedly connected with a second fixed nut, the second fixed pin is located between the limiting round rod and the first fixed pin, a power-assisting rod is rotatably connected to the support frame, a power-assisting tube is penetrated on the power-assisting rod, the power-assisting tube is sleeved on the second fixed pin, and the power-assisting rod is located in the support frame.
[0012] By adopting the above technical solution, since the flush rod itself has a large mass, the airport operator only needs to manually rotate the flush rod toward the bottom plate and straighten the messy container plates, which requires a lot of force. Therefore, the force required for the airport operator to push the flush rod can be reduced by the assistance of the power rod, thereby facilitating the work of the airport operator.
[0013] The present invention is further configured as follows: an inclined plate is provided at one end of the power assist rod close to the limiting round rod, and the inclined plate can be in contact with the outer side wall of the flush rod.
[0014] By adopting the above technical scheme, when the airport operators use the booster rod to assist the flush rod to straighten the messy container pallets, the flush rod will be in contact with the edge of the booster rod for a long time. In the long run, the side wall of the flush rod is easy to sink inward, and the flush rod is easy to break in the later stage; therefore, by setting the inclined plate, when the booster rod is in contact with the limiting round rod, the inclined plate can be in contact with the outer side wall of the flush rod, thereby increasing the contact force area between the flush rod and the booster rod, reducing the force when the flush rod is in contact with the edge of the booster rod, and reducing the occurrence of the outer side wall of the flush rod being sunken inward.
[0015] The present invention is further configured as follows: protective rings are arranged on the side walls around the inclined plate, and the protective rings can be abutted against the flush rods.
[0016] By adopting the above technical solution, the protective ring has better flexibility and can further protect the outer side wall of the flush rod, further reducing the stress when the flush rod and the power rod edges collide with each other, and reducing the occurrence of the outer side wall of the flush rod being concave inward.
[0017] The present invention is further configured as follows: a plurality of limit grooves are provided on the first fixing nut and the second fixing nut, the limit grooves are provided along the length direction of the first fixing pin shaft, and the plurality of limit grooves are evenly arranged along the circumferential direction of the first fixing nut and the second fixing nut, a fixing hole is provided on the first fixing pin shaft and the second fixing pin shaft, a limit opening pin is inserted in the fixing hole, and one end of the limit opening pin is embedded in the limit groove.
[0018] By adopting the above technical solution, the positions of the first fixing nut and the second fixing nut are restricted by the limiting cotter pin, thereby improving the stability of the connection between the first fixing pin shaft and the second fixing pin shaft on the support frame.
[0019] The present invention is further configured as follows: an end of the front frame and the plurality of flush rods away from the bottom plate is provided with an inclined rod, and the inclined rod is inclinedly arranged along a direction close to the bottom plate.
[0020] By adopting the above technical solution and setting the tilting rod, when the forklift slowly places a number of stacked pallets from the top of the pallet stacker onto the bottom plate, it is difficult for the pallets to be scratched or limited by the sharp edges and corners of the front frame or the end of the flush rod, thereby improving the efficiency of airport operators in placing pallets. At the same time, the setting of the tilting rod shifts the center of gravity of the flush rod, and the flush rod can automatically tilt from the state of being in contact with the outer wall of the bottom plate to the direction close to the limiting round rod under the action of gravity.
[0021] The present invention is further configured as follows: the protrusion is provided with a sliding hole along its length direction, a plurality of rollers are arranged on the inner side wall of the sliding hole, the rollers are rotatably connected to the protrusion, and the rollers can roll along the length direction of the bottom plate.
[0022] By adopting the above technical solution, the roller is used to convert the sliding friction with the container plate into rolling friction, which facilitates the taking and placing of the container plate and reduces the wear of the container plate.
[0023] The present invention is further configured as follows: two limit plates are arranged at one end of the bottom plate along its length direction and away from the front end frame.
[0024] By adopting the above technical solution, once the container plate tends to move in the length direction of the base plate, rolling friction occurs between the roller and the container plate, which easily causes the container plate to slide. Therefore, a limit plate is provided at the end of the base plate away from the front end frame to limit the container plate, thereby improving the stability of the container plate on the base plate.
[0025] The present invention is further configured as follows: a limiting frame is provided at the limiting plate of the bottom plate, the upper end surface of the limiting frame is in the same horizontal plane as the top wall of the bottom plate, a rotating rod is penetrated by the limiting frame, a waist-shaped hole is provided on the limiting plate, the rotating rod is inserted into the waist-shaped hole, the limiting plate can rotate in the limiting frame, and a side wall of the limiting plate can be in the same horizontal plane as the upper end surface of the limiting frame.
[0026] By adopting the above technical solution, the airport operator uses a forklift to place the container pallet on the bottom plate, the fork of the forklift is located between adjacent protrusions, all the container pallets are placed on the protrusions, and the fork of the forklift continues to descend. There are gaps between the fork of the forklift and the container pallet and the bottom plate; the airport operator rotates the limit plate again so that the limit plate is exposed to the limit frame, and the rotating rod is against the inner wall of the waist-shaped hole away from the ground, and the limit plate is limited at this time; at this time, the fork of the forklift is pulled out, and when it is necessary to remove the container pallets closest to the bottom plate, the limit plate can be turned down so that the container pallet can be removed smoothly.
[0027] In summary, the present invention has the following beneficial effects:
[0028] 1. The flush rod is used to regulate the pallet, reducing the risk of the pallet falling at high places due to the disorderly stacking of the pallet;
[0029] 2. The limit plate can be rotated into the limit frame, which ensures the limit effect of the container pallet every time without increasing the difficulty of the airport operator's work. BRIEF DESCRIPTION OF THE DRAWINGS
