Description

Technical Field

[0001] This utility model relates to the field of cargo handling vehicles, specifically a multi-functional lean pipe trolley. Background Technology

[0002] Lean pipe trolley is a flexible material handling equipment developed based on the lean production concept. Its core consists of plastic-coated steel pipes, flexibly splicable connectors, and auxiliary accessories such as shelves, guardrails, and casters. In the production workshop, it is widely used for material transfer between processes, material replenishment next to the assembly line, and temporary material storage. It is an important auxiliary tool for optimizing production processes and improving operational flexibility.

[0003] In the current production line's item collection and handling process, operators generally use collection boxes and ordinary trolleys. Typically, empty collection boxes are first placed on ordinary trolleys. Then, the operator stands next to the production line workbench and manually picks up the items on the workbench one by one and puts them into the collection box. When a single collection box is full, a new empty collection box is stacked on top of it, and the item placement operation is repeated. Usually, six collection boxes are filled and stacked neatly at a time. Once all the planned collection boxes are full, the operator pushes the trolley to transfer these stacked collection boxes to the designated storage area or the next process station in one go, completing a single collection and handling task.

[0004] Because the initial layer height of ordinary trolleys is relatively low, the first layer of collection boxes placed on the trolley is close to the ground. When operators place items into these bottom boxes, they must frequently bend over. Repeating this action for a long time can easily lead to soreness in the lower back muscles. Furthermore, when it is necessary to unload the collection boxes full of items from the trolley and transfer them to a placement platform that is half a meter high, operators must lift the collection boxes with both hands, which weigh a total of 13 kg, and overcome gravity to move them to the placement platform. This operation must be completed one by one, and repeated lifting can easily cause fatigue in the arm and shoulder muscles. Therefore, it requires a lot of physical strength for personnel to move collection boxes containing items, resulting in low efficiency in the collection and handling of items. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multi-functional lean pipe trolley to solve the technical problems mentioned in the background.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The lifting frame 2 has a first slider 201 fixed at its end, and the first slider 201 is sleeved on the structural tube of the transport vehicle 1. The bottom of the gas spring 204 is fixedly installed on the structural tube of the transport vehicle 1. A first connecting pipe 202 is fixed on the structural tube of the transport vehicle 1. The two ends of the first connecting pipe 202 are connected to anti-tipping pipes 203. The anti-tipping pipes 203 block the two sides of the collection box placed above the transport vehicle 1 to prevent the collection box from swaying left and right.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The top of the transport vehicle 1 is equipped with a handrail 5.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 6The front end of the transport vehicle 1 is provided with two sets of blocking pipes 6. The bottom of the blocking pipe 6 is connected to a third rope 605. The end of the third rope 605 is connected to a sixth connecting pipe 603. The end of the sixth connecting pipe 603 is equipped with a drive pipe 601. The outer wall of the drive pipe 601 is fitted with a limiting pipe 602. One end of the drive pipe 601 is provided with an impact pipe 604. The outer wall of the structural pipe of the transport vehicle 1 is fixed with a thirteenth pulley 606. The third rope 605 passes through the thirteenth pulley 606. The blocking pipe 6 blocks the collection box placed above the transport vehicle 1 to prevent the collection box from sliding down from the front end of the transport vehicle 1 via the roller 102.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 6 The bottom of the blocking tube 6 is fixedly connected to a second spring 607, and the top of the second spring 607 is connected to the structural tube of the transport vehicle 1. When the transport vehicle 1 is no longer in contact with the placement platform, the impact tube 604 no longer has an external force of squeezing and pushing. At this time, the second spring 607, which is under tension, pulls the blocking tube 6 back to its original position.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 — Figure 6 The outer wall of the slide tube 302 and the structural tube of the transport vehicle 1, as well as the inner walls of the first slider 201, the second slider 301, the third slider 305 and the fourth slider 4, are all set as regular dodecagons. When the first slider 201, the second slider 301, the third slider 305 and the fourth slider 4 slide, rotational sliding will not occur.

[0042] In practical operation, when personnel collect items from the assembly line workbench, they first control two sets of gas springs 204 simultaneously via controller 205 on one side of the transport vehicle 1 to raise the lifting frames 2 on both sides of the top of the transport vehicle 1 to their highest position. Then, personnel place two sets of collection boxes horizontally on the lifting frames 2. When the two sets of collection boxes are full, personnel can again control the gas springs 204 via controller 205 to move the lifting frames 2 downward to a suitable height. When six sets of collection boxes are piled up on top of the lifting frames 2, the lifting frames 2 descend to be level with the conveyor frame 101, allowing the collection boxes at the bottom to be stacked on the conveyor frame. On the multiple sets of rollers 102 installed on the top of 101, since the length of the lifting frame 2 is equal to the width of the two sets of collection boxes, when the 6 sets of collection boxes are stacked on top of the transport vehicle 1, the two sets of blocking pipes 6 at the front of the transport vehicle 1 block the collection boxes to prevent the collection boxes from sliding off the rollers 102 from the front of the transport vehicle 1. When personnel need to push the transport vehicle 1, they press the handrail 5 down, so that the handrail 5 drives the second connecting pipe 501 to rotate upward around the rotating rod 507 through the rotating rod 507. The rotating second connecting pipe 501 drives the third connecting pipe 503 to lift upward, and the brake foot 506 at the bottom of the third connecting pipe 503 leaves the ground. When the operator moves the transport vehicle 1 to the placement platform at the same height as the conveyor rack 101, the operator presses the two sets of impact tubes 604 at the front of the transport vehicle 1 against the side wall of the placement platform, causing the impact tubes 604 to retract inwards into the transport vehicle 1. The impact tubes 604 drive the sixth connecting tube 603 to move through the drive tube 601 fixedly connected to the bottom, causing the sixth connecting tube 603 to pull the two sets of third ropes 605 blocking tubes 6 fixedly connected to its outer wall. Because the third ropes 605 pass through the thirteenth pulley 606, the third ropes 605 pull the blocking tubes 6 vertically downwards, allowing the collection box above the transport vehicle 1 to be placed on the rollers. 102 slides upwards. When the blocking pipe 6 releases the restriction on the collection box, the person releases the handrail 5. The first spring 508, which is under tension, drives the handrail 5 to return to its original position through the second connecting pipe 501, so that the brake foot 506 is pressed into contact with the ground again. Then, the person steps down on the pedal pipe 306, so that the pedal pipe 306 drives the third slider 305 to slide vertically downwards along the structural pipe of the transport vehicle 1. When the third slider 305 slides downwards, the third slider 305 pulls the first rope 304 through the first pulley 307 and the fourth pulley 309 fixedly installed on its outer wall, so that the first pulley 307 and the first fixed block 303 are... The length of the first rope 304 between the first pulley 307 and the first fixed block 303 increases due to the increased tension, while the length of the first rope 304 between the seventh pulley 313 and the second fixed block 315 decreases. This causes the first rope 304 to be pulled by the eighth pulley 314 fixedly installed on one side of the push rod 3, thereby causing the push rod 3 to slide towards the front end of the transport vehicle 1. When the push rod 3 slides, it can push the collection boxes stacked on the transport vehicle 1 onto the placement platform. The rollers on the placement platform and the rollers 102 on the conveyor frame 101 are on the same horizontal line, allowing the collection boxes to be easily pushed by the push rod. 3. Push rod 3 is moved to the placement platform. During the movement of push rod 3, the second rope 403 fixedly connected to one side of push rod 3 pulls the fourth slider 4, causing the fourth slider 4 to slide vertically upward along the structural tube of the transport vehicle 1. When the personnel release the foot tube 306, since the fourth slider 4 is fixed to one side of the counterweight tube 401, the counterweight tube 401 drives the fourth slider 4 to slide vertically downward due to its own weight. This causes the second rope 403 to pull push rod 3 back to its original position. The return of push rod 3 causes push rod 3 to pull the first rope 304 through the eighth pulley 314, causing the first rope 304 to pull the third slider 305 back to its initial position.
