Description

Technical Field

[0001] This application relates to the field of on-site logistics and transportation technology, and in particular to a trolley for transporting automobile beams at workstations. Background Technology

[0002] The chassis beam is the main load-bearing component of a truck, bearing almost the entire weight of the cargo. The quality of the chassis beam affects the service life of the entire vehicle and driving safety. During the manufacturing of truck chassis beams in the workshop, a transfer trolley is typically used to move the chassis beam from one workstation to another to facilitate further processing. A search revealed a patent document with authorization announcement number CN210084277U, which discloses a transfer and transportation trolley for automobile beam workstations. The trolley includes a main body, a movable roller, and a control box. A fixed bracket is bolted to the left side of the main body, and a winding roller is fixedly installed inside the bracket. The control box is located at the rear end of the fixed bracket, and a pressure roller is located at the lower right end of the fixed bracket. A winding wire is wound around the outside of the winding roller and connected to a movable motor to the right via the pressure roller. Left and right movable guide rails are fixed to the front and rear of the right side of the fixed bracket using countersunk hexagonal bolts. A transport plate is located at the top right end of the movable guide rails. The fixed bracket design facilitates the fixed installation of the winding roller inside and the control box to control the rotation and winding of the wire. This transforms a traditional sliding-wire flatbed trolley into an automatic winding and unwinding electric flatbed trolley, solving the problem of road surface covers easily damaging foreign objects that could enter the trench and damage the sliding wire.

[0003] The above solution still has at least the following shortcomings in actual use: After placing the car beam on the transport platform and controlling the transport platform to move to the required work position, it is necessary to control the transport platform to move back to its original position before the next car beam can be transported. The transport steps are cumbersome, not flexible enough, increase working time and reduce work efficiency.

[0004] Therefore, we propose a trolley for transporting automobile beams at the work station to solve the above problems. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] See Figure 1 , Figure 2 and Figure 3 This application provides a trolley for transporting automobile beams at workstations, including a racetrack-shaped guide rail 1 laid and fixed in the automobile beam production workshop, and a trolley body set on the racetrack-shaped guide rail 1. The trolley body is used to carry and transport automobile beams. There are no fewer than two trolley bodies. By setting no fewer than two trolley bodies, transportation tasks can be flexibly arranged according to production needs, adapting to the transportation of automobile beams with different production rhythms and batches. The layout of the racetrack-shaped guide rail 1 can plan a more reasonable transportation route within the limited space of the automobile beam production workshop, facilitating the movement of the trolley bodies between various workstations, improving the space utilization rate of the entire production workshop and the flexibility of the production process. The transport carrier plate 3 is used to support the automobile beams, wherein:

[0036] The main body of the transport trolley includes a vehicle body 2, a transport platform 3, and a drive mechanism. The transport platform 3 is fixedly installed on the top of the vehicle body 2 and is used to support the vehicle beam. An anti-slip rubber pad 4 is fixedly installed on the top of the transport platform 3. The anti-slip rubber pad 4 can effectively prevent the vehicle beam from sliding during transportation, further ensuring the safety and reliability of transportation, and can also effectively avoid direct contact between the vehicle beam and the transport platform 3 to prevent hard collisions and damage to the outer surface of the vehicle beam. The bottom of the vehicle body 2 has a mounting groove 5, and the vehicle body 2 has a mounting cavity 6 located above the mounting groove 5. The four sides of the mounting cavity 6 are open. The top of the racetrack-shaped guide rail 1 extends into the mounting groove 5. The drive mechanism is located between the racetrack-shaped guide rail 1 and the car body 2. The drive mechanism controls the movement of the car body 2 along the racetrack-shaped guide rail 1. The drive mechanism includes a racetrack-shaped internal gear ring 7, a drive shaft 8, a drive gear 9, a motor 10, a transmission gear 11, a second drive shaft 12, a second transmission gear 13, a second drive gear 14, and a racetrack-shaped external gear ring 15. The racetrack-shaped internal gear ring 7 is fixedly installed on the inner wall of the racetrack-shaped guide rail 1. The drive shaft 8 is rotatably installed on the top inner wall of the mounting groove 5. The drive gear 9 is fixedly installed at the bottom end of the drive shaft 8 and meshes with the racetrack-shaped internal gear ring 7. The motor 10 is fixedly installed on the top inner wall of the mounting cavity 6. The top end of the drive shaft 8 is connected to the motor 15. The output shaft end is fixedly connected, and the transmission gear 11 is fixedly mounted on the drive shaft 8 and located in the mounting cavity 6. The drive shaft 12 is rotatably mounted on the top inner wall of the mounting groove 5, and the top end of the drive shaft 12 extends into the mounting cavity 6. The transmission gear 13 is fixedly mounted on the top end of the drive shaft 12 and meshes with the transmission gear 11. The drive gear 14 is fixedly mounted on the bottom end of the drive shaft 12. The racetrack-shaped external gear ring 15 is fixedly mounted on the outer side wall of the racetrack-shaped guide rail 1, and the drive gear 14 meshes with the racetrack-shaped external gear ring 15. This multi-gear transmission design can not only further enhance the stability of power transmission, but also utilize the drive gear 19 and the racetrack-shaped internal gear ring 15 to achieve the desired effect. The meshing transmission of ring 7 and the meshing transmission of drive gear 14 and racetrack-shaped external gear ring 15, through their combined action, can better balance the force on the main body of the transport trolley during operation, reduce the risk of derailment caused by uneven force on one side, extend the service life of the equipment, and enhance the stability of the transport trolley when moving. It should be noted that motor 10 is a reversible motor, which can control drive shaft 8 to rotate in the forward or reverse direction, and can change the direction of movement of the transport trolley as needed. The wiring and control methods of motor 10 are mature technologies in this field and will not be elaborated further in this article.

[0037] In this embodiment, a through hole 1 communicating with the mounting cavity 6 is provided on the top inner wall of the mounting groove 5. The top end of the drive shaft 8 passes through the through hole 1, and a bearing 1 is fixedly mounted on the drive shaft 8. The outer ring of the bearing 1 is fixedly connected to the inner wall of the through hole 1.

[0038] In this embodiment, a through hole 2 communicating with the mounting cavity 6 is provided on the top inner wall of the mounting groove 5. The top end of the drive shaft 2 12 passes through the through hole 2. A bearing 2 is fixedly mounted on the drive shaft 2 12. The outer ring of the bearing 2 is fixedly connected to the inner wall of the through hole 2.

[0039] In this embodiment, the width of the mounting groove 5 is greater than the sum of the thicknesses of the racetrack-shaped guide rail 1, the racetrack-shaped internal gear ring 7, and the racetrack-shaped external gear ring 15.

[0040] In this embodiment, four support columns 16 are fixedly installed at the bottom of the vehicle body 2. The four support columns 16 are symmetrically distributed in pairs. The bottom end of the support column 16 is an arc-shaped surface structure, and the bottom end of the four support columns 16 is in contact with the ground. The four support columns 16 can stably support the vehicle body 2.

[0041] With the above structure, the working principle of the automobile beam transfer and transportation trolley provided in this application is as follows:

[0042] When the motor 10 is started, the output shaft of the motor 10 drives the drive shaft 8, which is fixedly connected to it, to rotate. When the drive shaft 8 rotates, the drive gear 9 and the transmission gear 11 also rotate synchronously. Since the drive gear 9 meshes with the racetrack-shaped internal gear ring 7, during the rotation of the drive gear 9, a force is generated along the tangential direction of the racetrack-shaped internal gear ring 7 due to the meshing action between the gears. This force causes the vehicle body 2 to move relative to the fixed racetrack-shaped guide rail 1, thereby driving the entire transport vehicle body to start moving along the racetrack-shaped guide rail 1, realizing the initial driving forward movement to support and transport the vehicle beam.

[0043] Meanwhile, the meshing transmission action of transmission gear 11 and transmission gear 213 causes drive shaft 212 to rotate. Drive shaft 212 drives drive gear 214 to rotate. Since drive gear 214 meshes with racetrack-shaped external gear ring 15, when drive gear 214 rotates, it further assists the vehicle body 2 to move along the racetrack-shaped guide rail 1 by relying on its meshing relationship with racetrack-shaped external gear ring 15. Furthermore, by utilizing the meshing transmission action of drive gear 19 and racetrack-shaped internal gear ring 7, and the meshing transmission action of drive gear 214 and racetrack-shaped external gear ring 15, the combined action of the two makes the movement of the transport trolley body on the racetrack-shaped guide rail 1 more stable and smooth, ensuring the stability of the automobile beam during the transfer and transportation process between workstations, and successfully completing the workstation transfer and transportation task of the automobile beam.

[0044] Furthermore, by setting up no fewer than two transport trolleys, transport tasks can be flexibly arranged according to production needs, adapting to different production rhythms and batches of automobile beams. The layout of the runway-shaped guide rail 1 can plan a more reasonable transport route within the limited space of the automobile beam production workshop, facilitating the movement of the transport trolleys between various workstations, improving the space utilization rate and production process flexibility of the entire production workshop, and increasing work efficiency.
