Description

Technical Field

[0001] The invention discloses a tire transport box trolley for an automobile production line, which is used for transporting tires in the automobile production line and relates to the technical field of design and manufacturing of tire transport trolleys for automobile production lines. Background Art

[0002] Various types of transport trolleys are running on all automobile production lines. Their purpose is to transport various automobile parts to different assembly stations on the production line. The operation of these trolleys can greatly save the space occupied on the assembly line, and the required parts can be transported to different stations at a fixed time and location according to production tasks and instructions. In particular, various modern automobile production lines require both high efficiency and bright and tidy production lines. However, the average aisle width in the existing factory is about 4500mm. However, due to process conditions, the trolleys for transporting parts are generally large, and there are many vehicles, which are prone to congestion and human-vehicle contact safety accidents. Tire transportation is 4 units / time, and 4 groups of tires are placed at 4 different parts openings on the trolley. After arriving at the equipment on the production line side, the operator needs to get off the trolley and push the 4 groups of tires into the equipment one by one.

[0003] The existing technology has the following problems:

[0004] Safety hazard: Due to the insufficient width of the passage, the large number of other vehicles passing through the area, and the fact that the operator is working with his back to the oncoming traffic, there is a safety hazard of being hit by vehicles coming from behind.

[0005] Waste of working time: The tire line-side loading operation can only be performed by personnel getting off the vehicle and manually pushing the tires in. The operation steps are: get off the vehicle and move → push in the first set of tires → move → push in the second set of tires → move → push in the third set of tires → move → push in the fourth set of tires → return and get on the vehicle, a total of 9 steps, taking 36 seconds. Summary of the Invention

[0006] The present invention is aimed at the defects of the prior art. After overall design, it proposes a tire transport box trolley for automobile production line, which includes a tire pushing mechanism, a synchronous moving mechanism for pushing door and a box structure:

[0033] The present invention includes a tire pushing mechanism, a door pushing synchronous movement mechanism and a box structure:

[0034] The tire pushing mechanism includes a pushing door 13, a tire roller 12, an exit door handle 1, and a tire unloading pusher 2; the pushing door 13 is arranged at the lower end of the main push rod 4 and a plurality of passive push rods 8; the exit door handle 1 is arranged at the end of the exit sliding door 17 close to the tractor; the exit door handle 1 and the tire unloading pusher 2 are arranged at the front end because the tractor is in the front, and the employee driving the tractor can either drive the vehicle or use the exit door handle 1 to open the exit sliding door 17 without getting off the vehicle, and then push the tire unloading pusher 2 to push out the tire placed on the tire roller 12, thereby reducing the process of getting off the vehicle to carry the tire, which can save time, improve efficiency, and reduce the possibility of employee injuries caused by congestion in the passage;

[0035] The exit sliding door 17 is arranged in a chute on one side of the tire transport box 11 where the tire 16 is pushed out. The exit sliding door 17 is arranged in the chute so that the employee can open and close it without shifting.

[0036] The chute on the tire outlet side is the same as the door chute 14 on the tire entry side;

[0037] The tire roller 12 is provided on the bottom surface of the tire transport box 11, and the tire 16 is placed on the tire roller 12 after being pushed in, so as to be pushed out toward the exit side; the tire roller 12 is provided to facilitate the loading and pushing out of the tire 16;

[0038] The tire unloading pusher 2 is arranged on the circular surface of the main push rod 4 close to one end of the main push rod rotating shaft 3 facing one end of the tractor, and a pushing door 13 is arranged below the other end of the main push rod 4. When the tire pusher 2 is rotated, one end of the main push rod 4 is rotated and positioned on the main push rod rotating shaft 3, and the other end drives the pushing door 13 to move, and pushes the tire loaded on the tire roller 12 in the tire handling box 11 to the exit side;

[0039] The push door synchronous movement mechanism includes a main push rod shaft 3, a main push rod 4, a limit column 5, a push rod connecting column 6, a synchronous connecting rod 7, a passive push rod 8, a passive push rod shaft 9, and a passive push rod connecting column 10; the push rod shaft includes a main push rod shaft 3 and each passive push rod shaft 9, the main push rod 4 and the passive push rod 8 are arranged laterally on the top surface of the tire carrying box 11, and the push rod shaft is arranged on the side of the main push rod 4 and the passive push rod 8 close to the tire outlet, and the main push rod shaft 3 and each passive push rod shaft 9 are used to make one end of the main push rod 4 and the passive push rod 8 rotate in place when pushing, and the other end drives the push door 1 3 rotates and pushes the tire toward the exit; the push rod connecting column 6 and the passive push rod connecting column 10 are connected by the synchronous connecting rod 7 of each tire loading compartment, and the push rod connecting column 6 and the passive push rod connecting column 10 are connected to each main push rod 4 and the passive push rod 8 through the synchronous connecting rod 7, constituting the synchronous movement of each push door 13, and the tire of each compartment is pushed toward the exit through the push door 13 provided at the lower end of the main push rod 4 and the passive push rod 8; the synchronous movement mechanism provided enables one person to push the tire unloading pusher 2 at one time to push all the tires placed on the tire rollers 12 of the four compartments out of the tire transporter 11;

[0040] The box structure is composed of a tire handling box 11, tire rollers 12, a pushing door 13, an entrance door slide 14, and an exit door tire blocking column 15; side frames are provided on the four sides of the box structure, and the box structure is provided with four compartments for storing tires, and a tire roller 12 is provided on the bottom surface of each compartment; on both sides of the tire handling box 11 are a tire outlet and a tire inlet, and on one side of the outlet is provided an outlet sliding door 17, which is provided in the sliding door slide 14 on both sides, and tire blocking rods 15 are provided at intervals on the outlet sliding door; the tire blocking rod 15 is provided in the middle position of each of the compartments, and is staggered with the compartment pillars 18 of each compartment of the tire handling box 11. When the sliding door is opened, the set tire blocking rod 15 coincides with the compartment pillars 18, which is convenient for the tire to be pushed out. When the sliding door 17 is closed during transportation The tire blocking rod 15 is misaligned with the compartment pillar 18, forming an obstruction to the tire. In this way, when the tire transport box 11 is in the process of transportation, the tire cannot fall down by itself due to the obstruction of the interval pillar 18. When the tire transport box 11 arrives at the work station where the tire needs to be unloaded, the driver pulls open the exit door handle 1 and pulls out the tire blocking rod 15 for a while, so that the compartment pillar 18 and the tire blocking rod 15 coincide with each other, thus opening the passage for unloading the tire. Then, the tire unloading push handle 2 is lifted and rotated to the right. Driven by the main push rod 4, the push door 13 arranged at the lower end of the main push rod 4 starts to rotate under the positioning of the main push rod rotating shaft 3. Due to the connection of the synchronous connecting rod 7 arranged on the main push rod 4 and the passive push rod 8, all the push doors rotate synchronously, and the tires loaded in each compartment are pushed out of the tire transport box, completing the task of transporting the tires once.
