Therefore, those skilled in the art have provided a mold steel billet transfer trolley to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this utility model is to provide a mold steel billet transfer trolley to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:

A universal wheel is movably connected to the middle of the bottom end of the universal shaft.

[0006] As a further embodiment of this utility model: the lower right side of the billet transfer trolley is fixedly connected to the transfer trolley traction device, and the middle right end of the transfer trolley traction device is fixedly connected to the traction frame.
[0007] As a further embodiment of this utility model: the inner wall surface of the top center through-hole of the traction frame is movably connected to the traction steering shaft, and the lower side of the outer wall surface of the traction steering shaft is movably connected to the steering shaft fixing nut at the bottom center through-hole of the traction frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The operator holds the guide handle and pushes the billet transfer trolley forward. Because the casters can rotate 360 degrees and the ball bearings reduce rotational resistance, the trolley can easily change direction, navigating flexibly in complex work environments such as workshops to quickly reach the location where the mold steel billets need to be transferred. The guide handle provides a stable grip point for the operator, allowing precise control of the trolley's direction and improving transfer accuracy. During movement, if encountering uneven surfaces, the vibrations from the casters are transmitted to the hydraulic damper via hydraulic spring rods. The hydraulic spring rods first use their own elasticity to initially buffer and absorb some of the vibration energy. Then, the fluid inside the hydraulic damper flows under the action of the piston, generating damping force to further dissipate vibration energy and reduce vibration. The vibration damping is transmitted to the vehicle body, making the billet transfer trolley move more smoothly. This not only protects the mold steel billets from damage caused by excessive bumps, but also extends the service life of the billet transfer trolley itself and reduces equipment maintenance costs. When the billet transfer trolley reaches the designated position for loading or unloading billets, the operator can step on the universal wheel lock to lock the universal wheels. The universal wheel lock uses a mechanical structure to lock the rotating wheel of the universal wheel, preventing it from rotating, thus completely fixing the billet transfer trolley in the current position. This further enhances the stability of the trolley during the loading and unloading of billets and avoids safety accidents caused by accidental rotation of the universal wheels. The flexible universal wheel design and easy-to-grip guide handles enable the billet transfer trolley to reach the billet storage area quickly and accurately, reducing the time wasted during the movement process. Compared to traditional fixed-wheel transfer trolleys, this method can increase work efficiency by 40%-50%, significantly improving the transfer speed of mold steel blanks. The shock absorption system composed of hydraulic dampers and hydraulic spring rods, along with the reduced rotational resistance from ball bearings, makes it easier for operators to push the blank transfer trolley, reducing physical exertion. It can effectively prevent mold steel blanks from shifting or colliding due to bumps and vibrations during transportation, thus avoiding surface damage and affecting the quality of subsequent processing.
[0015] 2. When assembling the mold steel billet, the operator opens the latch in the sliding plate slot and rotates the sliding plate opening and closing shaft to a suitable angle, so that the mold steel billet sliding plate forms a certain inclination angle with the ground, which facilitates the placement of the billet. The mold steel billet of appropriate size is placed on the mold steel billet sliding plate. Under its own weight and with the help of manual pushing, the billet slides into the trolley along the sliding plate guide shaft in the sliding plate groove. The sliding plate guide shaft rotates during the billet sliding, reducing the friction between the billet and the mold steel billet sliding plate, allowing the billet to slide more smoothly. The opening and closing design of the mold steel billet sliding plate and the application of the sliding plate guide shaft greatly facilitate the loading and unloading operation of the billet. The billet can slide quickly and smoothly along the sliding plate guide shaft, reducing the workload and time of manual handling. Compared with the traditional manual loading and unloading method, the loading and unloading efficiency can be increased by more than 50%. Attached Figure Description

The right side of the billet transfer trolley 1... A transfer trolley traction device 11 is fixedly connected to the lower side of the transfer trolley traction device 11. A traction frame 12 is fixedly connected to the middle of the right end of the transfer trolley traction device 11. A traction steering shaft 13 is movably connected to the inner wall surface of the middle through-hole at the top of the traction frame 12. A steering shaft fixing nut 14 is movably connected to the lower side of the outer wall surface of the traction steering shaft 13 at the middle through-hole at the bottom of the traction frame 12.

The inner wall surfaces of the billet partition slots 23 are movably connected to the billet partitions 24.
[0023] The working principle of this utility model is as follows: When using this utility model, firstly, the operator holds the guide handle 2 and pushes the billet transfer trolley 1 forward. Since the universal wheels 9 can rotate 360 degrees and the ball bearings 7 reduce rotational resistance, the billet transfer trolley 1 can easily change its direction of travel, flexibly navigating complex working environments such as workshops and quickly reaching the location where the mold steel billet needs to be transferred. The guide handle 2 provides the operator with a stable grip point, enabling precise control of the billet transfer trolley 1's direction of travel and improving the accuracy of the transfer. During movement, if the vehicle encounters an uneven surface, the vibration experienced by the universal wheels 9 will be transmitted to the hydraulic damper 4 through the hydraulic spring rod 5. The hydraulic spring rod 5 first utilizes... The springs themselves provide initial cushioning, absorbing some of the vibration energy. Then, the fluid in the hydraulic damper 4 flows under the action of the piston, generating damping force to further dissipate vibration energy and reduce the transmission of vibration to the vehicle body, making the billet transfer trolley 1 move more smoothly. This not only protects the mold steel billet from damage due to excessive bumps but also extends the service life of the billet transfer trolley 1 itself, reducing equipment maintenance costs. When the billet transfer trolley reaches the designated position for loading or unloading billets, the operator steps on the universal wheel lock 10 to lock the universal wheel 9. The universal wheel lock 10, through a mechanical structure, locks the rotating wheel of the universal wheel 9, preventing it from rotating, thus completely fixing the billet transfer trolley 1 in place. The current position further enhances the stability of the trolley during the loading and unloading of blanks, avoiding safety accidents caused by the accidental rotation of the universal wheel 9. Then, when assembling the mold steel blank, the operator moves the lever 20 in the sliding plate slot 21 and rotates it to a suitable angle through the sliding plate opening and closing shaft 16, so that the mold steel blank sliding plate 15 forms a certain tilt angle with the ground, which facilitates the placement of the blank. The mold steel blank of appropriate size is placed on the mold steel blank sliding plate 15. Under the action of its own weight and manual assistance, the blank slides into the trolley along the sliding plate guide shaft 18 in the sliding plate groove 17. The sliding plate guide shaft 18 rotates during the sliding of the blank, reducing the friction between the blank and the mold steel blank sliding plate 15. This allows the billet to slide more smoothly. In addition, the operator can insert a billet partition 24 between the inner surfaces of the billet partition slot 23 according to the actual size. The billet partition 24 is made of metal sheet and has a certain strength and rigidity to prevent different billets from colliding and squeezing with each other, dividing the loading area of the billet transfer trolley 1 into two independent spaces, and placing different billets on the billet partition 24 for classification. After assembly, the operator lifts the mold steel billet sliding plate 15 and presses it against the surface of the sliding plate limiting part 22. The rotation shaft of the locking rod 20 is on the inner wall surface of the locking shaft 19. By rotating the locking rod 20, the locking rod 20 and the sliding plate slot 21 are engaged with each other, and the mold steel billet sliding plate 15 is effectively fixed.Finally, when long-distance transfer of mold steel billets is required, the tractor of the tractor vehicle is engaged on the inner surface of the tractor frame 12, the traction steering shaft 13 passes through the tractor frame 12 and the tractor of the tractor vehicle, and the steering shaft fixing nut 14 is tightened to ensure a secure connection. The external tractor vehicle is then started, and its power is transmitted to the transfer trolley tractor 11 through the tractor frame 12, thereby driving the billet transfer trolley 1 forward. During the traction process, if a turn is required, the traction steering shaft 13 allows the tractor frame 12 to rotate a certain angle relative to the body of the billet transfer trolley 1, enabling the billet transfer trolley 1 to smoothly follow the tractor vehicle and achieve efficient and flexible long-distance transfer.
