Description

Technical Field

[0001] The utility model relates to the technical field of step-type trolleys, and more specifically, to a walking device of a step-type trolley. Background Art

[0002] In the fields of industrial production and logistics transportation, trolleys are widely used as an important handling tool. The stepping trolley realizes precise stepping motion through a series of mechanical transmission and control systems. It is usually composed of a trolley body, a drive device, a transmission mechanism, a guide device and a control system. The stepping trolley plays an important role in modern industrial production. Its appearance improves production efficiency, reduces labor intensity, and provides strong support for the development of enterprises.

[0003] The walking mechanism design of traditional trolleys is relatively simple, usually relying only on the wheels rolling on the track to achieve walking, and lacks an effective locking mechanism. When the trolley carries heavy objects or travels at high speed, it is prone to accidental sliding or deviation, which seriously affects the stability and reliability of the trolley's travel, and also brings safety hazards. During the transition between forward and backward, the power transmission of the trolley is not smooth enough, and it is difficult to ensure the stability of the trolley in different walking states. This not only reduces work efficiency, but may also cause damage to the transported items. Utility Model Content

[0012] Preferably, the bottom shape of the walking shoe matches the shape of the walking track.

[0013] Technical effects and advantages of this utility model:

[0014] 1. By setting up the walking mechanism, the locking pin on the walking shoe can be locked with the walking track when the trolley is moving forward and backward, ensuring that the trolley will not accidentally slide or deflect during the movement, greatly improving the stability and reliability of the trolley's movement. The moving wheels and walking shoes work together to realize the movement of the trolley under the push and pull of the push cylinder, so that both the thrust when moving forward and the pulling force when moving backward can effectively transmit power to ensure the stable operation of the trolley. When carrying heavy objects or moving at high speed, the locking function of the locking pin and the walking track and the stable rolling of the moving wheels provide strong guarantees for the safe operation of the trolley;

[0015] 2. By setting up a jacking mechanism, the jacking inclined block is driven upward by the jacking cylinder to achieve the purpose of adjusting the height of the positioning rod. It can be adjusted according to actual needs. The positioning rod can ensure that the trolley reaches the predetermined position accurately during operation, which enables the trolley to meet different work tasks and load requirements, and improves the adaptability and versatility of the trolley. When the trolley needs to be docked with other equipment, the positioning rod can ensure the accuracy of the docking and avoid deviations that affect production efficiency and product quality.

[0024] The walking mechanism includes a fixed block 4, which is fixedly installed at the bottom of the trolley frame 1. A fixed shell 5 is fixedly connected to the bottom of the fixed block 4, and a moving wheel 6 is installed inside the fixed shell 5. A hinged column 7 is fixedly connected to one side of the fixed shell 5, and a push cylinder 8 is hinged to one side of the hinged column 7. A walking boot 9 is provided at one end of the push cylinder 8. A fixed shaft 10 is fixedly connected to the inside of the walking boot 9, and a locking pin 11 is installed inside the walking boot 9. Locking grooves 12 are provided on both sides of the walking boot 9. Walking tracks 13 are provided at the bottom of the moving wheel 6 and the walking boot 9, and the moving wheel 6 and the walking boot 9 are both slidably connected to the walking track 13.

[0025] As attached Figure 2-4 As shown, one end of the fixed shaft 10 passes through the pushing cylinder 8 and extends to one side of the pushing cylinder 8. The fixed shaft 10 is rotatably connected to one end of the pushing cylinder 8 to facilitate the rotation of the pushing cylinder 8.

[0026] As attached Figure 1As shown, the top of the fixed block 4 passes through the trolley frame 1 and extends to the top of the trolley frame 1. A jacking mechanism is provided on the top of the fixed block 4. The jacking mechanism includes a jacking cylinder 16. The jacking cylinder 16 is fixed to the top of the fixed block 4. A jacking inclined block 15 is fixedly connected to the top of the jacking cylinder 16. The jacking inclined block 15 is fixed to one side of the connecting frame 2. A connecting platform 14 is fixedly installed between the connecting frame 2 and the positioning rod 3, which is convenient for adjusting the height of the positioning rod 3 and for positioning in different situations. The positioning rod can ensure that the trolley accurately reaches the predetermined position during operation. The trolley can meet different work tasks and load requirements, thereby improving the adaptability of the trolley. At the same time, when the trolley is docked with other equipment, the positioning rod can ensure the accuracy of the docking to avoid deviations that affect production efficiency and product quality.

[0027] As attached Figure 2-5 As shown, the locking pin 11 is slidably connected to the locking groove 12, which facilitates the movement of the locking pin 11 in the locking groove 12 and the locking of the trolley. The bottom shape of the walking shoe 9 matches the shape of the walking track 13, which ensures the stability of the movement of the walking shoe 9.

[0028] When the trolley needs to move forward, the pushing cylinder 8 starts to lift up, and the walking shoe 9 connected to one end of the pushing cylinder 8 rises under the action of the cylinder. At this time, the locking pin 11 on the walking shoe 9 returns to the right side of the locking groove 12 due to the lifting action of the pushing cylinder 8, and the locking pin 11 is locked with the walking track 13 to ensure that the walking shoe 9 does not slide during the forward movement. As the pushing cylinder 8 continues to lift up, the moving wheel 6 starts to move under the thrust of the pushing cylinder 8, and the moving wheel 6 installed inside the fixed shell 5 moves ahead under the push of the pushing cylinder 8. The moving wheel 6 rolls forward along the walking track 13, driving the trolley frame 1 and the upper connecting frame 2, positioning rod 3 and other structures to move forward together;

[0029] When the trolley needs to move backward, the pushing cylinder 8 starts to recover, and the pushing cylinder 8 drives the walking shoe 9 to move down. The locking pin 11 of the walking shoe 9 returns to the right side of the locking groove 12 due to the recovery action of the pushing cylinder 8, and the locking pin 11 is locked with the walking track 13 again to ensure the stability of the walking shoe 9 during the backward movement. Under the pulling force of the pushing cylinder 8, the moving wheel 6 starts to move backward. Under the pull of the pushing cylinder 8, the moving wheel 6 rolls backward along the walking track 13. The backward movement of the moving wheel 6 drives the trolley frame 1 and the various components above it to move backward together.
