Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to a low-space transverse connecting rod structure. Background Art

[0002] The support legs of a stacker are designed primarily to bear the weight of heavy objects and ensure the stability of the vehicle during operation. The support legs are usually fixed below the forks and cannot move up and down or extend and retract forward and backward. The vehicle body and the support legs move synchronously, so the support legs of a stacker usually cannot move laterally. In the actual process of transporting goods, the transport of parallel goods requires cumbersome operations before they can be changed, and it is difficult for operators and requires certain skills. To a certain extent, this increases the time cost and personnel training cost of the transport process. Based on this, the utility model proposes a low-space lateral movement connecting rod structure, which realizes the low-altitude lateral movement of the stacker support legs under the requirement that the distance between the bracket chassis and the ground is 100mm. Utility Model Content

[0003] The purpose of the utility model is to provide a low-space transverse connecting rod structure to solve the above-mentioned problems.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The utility model discloses a low-space transverse displacement connecting rod structure, comprising left and right symmetrically distributed supporting legs, a load-bearing wheel is provided at the bottom position of the front end of the supporting leg, and the rear end of the load-bearing wheel is provided with a cavity structure through symmetrically distributed partition one and partition two, a cam is provided in the cavity structure, and a transmission shaft is provided at the center of the cam; one end of the transmission shaft is rotatably provided on the partition one, and the other end passes through the partition two and extends to the bottom position of the rear end of the supporting leg; a connecting rod is provided at the end of the transmission shaft away from the cam, and the other end of the connecting rod is hingedly connected to the oblique rod; the other ends of the left and right oblique rods are hingedly connected to a fixing sleeve, and a telescopic mechanism is fixedly provided in the fixing sleeve.

[0006] Furthermore, a fork is provided above the supporting leg.

[0007] Furthermore, a groove is provided on the convex surface of the cam, and a roller is provided in the groove.

[0008] Furthermore, U-shaped hinge seats are symmetrically provided at both ends of the oblique rod.

[0009] Furthermore, the telescopic mechanism adopts a cylinder, a hydraulic cylinder or an electric push rod.

[0010] Furthermore, the telescopic end of the telescopic mechanism is fixedly connected to the fixing sleeve.

[0011] Furthermore, an outer side wall of the fixing sleeve is provided with a trunnion foot seat hingedly connected to the U-shaped hinge seat.

[0012] Furthermore, the movement direction of the roller is perpendicular to the movement direction of the load-bearing wheel.

[0013] Compared with the prior art, the beneficial technical effects of the present invention are:

[0014] The low-space lateral movement connecting rod structure of the utility model moves downward through the telescopic mechanism, driving the oblique rod to move outward in an arc shape, and the connecting rod hingedly connected to it rotates outward through a certain arc, and drives the transmission shaft to rotate outward together. During rotation, the convex surface of the cam gradually contacts the ground until it is fully in contact, and the load-bearing wheel is separated from the ground. The roller on the cam can move laterally relative to the load-bearing wheel, meeting the low-altitude lateral movement operation requirements of the stacker support legs, reducing the operating difficulty of the stacker, saving operating time, and improving handling efficiency.

[0020] like Figure 1-3 As shown, a low-space transverse linkage structure includes support legs 1 symmetrically distributed on the left and right sides. The support legs 1 are trough-type structures with an open bottom. A load-bearing wheel 6 is installed at the bottom position of the front end of the support leg 1, and the moving direction of the load-bearing wheel 6 is forward and backward.

[0021] The rear end of the load-bearing wheel 6 is equipped with a cavity structure through symmetrically distributed partitions 12 and 13. A cam 4 is installed in the cavity structure. The convex surface of the cam 4 is provided with a groove. A roller 5 is installed in the groove. The movement direction of the roller 5 is perpendicular to the movement direction of the load-bearing wheel 6, that is, the movement direction of the roller 5 is left and right. A transmission shaft 3 is installed in the center of the cam 4. Partitions 12 and 13 not only serve the purpose of isolation and protection, but also support the transmission shaft 3, making the rotation process of the transmission shaft 3 more stable. One end of the transmission shaft 3 is rotatably mounted on partition 12, and the other end passes through partition 2 13 and extends to the bottom position of the rear end of the support leg 1.

[0022] A connecting rod 7 is mounted on the end of the transmission shaft 3 away from the cam 4. This connecting rod 7 is fixedly connected to the transmission shaft 3, meaning that rotation of the connecting rod 7 drives the transmission shaft 3 in the same direction. The other end of the connecting rod 7 is hingedly connected to a diagonal rod 9, symmetrically mounted with U-shaped hinged mounts 8 at each end of the diagonal rod 9 to facilitate installation and disassembly during maintenance. The other ends of the left and right diagonal rods 9 are hingedly connected to a fixing sleeve 10. Mounted on the outer wall of the fixing sleeve 10 are trunnion feet, which are hingedly connected to the U-shaped hinged mounts 8.

[0023] A telescopic mechanism 11 is fixedly mounted within the fixed sleeve 10, with the telescopic end of the telescopic mechanism 11 fixedly connected to the fixed sleeve 10. The telescopic mechanism 11 is implemented using a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. In this embodiment, a hydraulic cylinder is used, and the stroke of the hydraulic cylinder is calculated based on the rotation angle of the cam 4. In this embodiment, the rotation angle of the cam 4 is 0 to 30 degrees.

[0024] A fork 2 is installed above the supporting leg 1 for transporting goods.

[0025] The action process of this utility model is as follows:

[0026] First, the convex surface of the cam 4 is pulled inward, and the load-bearing wheel 6 is in contact with the ground. The support leg 1 mainly moves in the forward and backward direction. When the support leg 1 needs to move laterally, the telescopic mechanism 11 is activated by the start button. The telescopic end of the telescopic mechanism 11 moves downward, and during this movement, it drives one end of the diagonal rod 9 to move together, and the other end of the diagonal rod 9 moves outward in an arc. Because the diagonal rod 9 is hinged to the connecting rod 7, it drives the connecting rod 7 to rotate outward, and when it rotates, it also drives the transmission shaft 3 to rotate outward. During this process, the convex surface of the cam 4 gradually contacts the ground until it is completely in contact with the ground, and the load-bearing wheel 6 separates from the ground. Finally, the stacker is pushed, and the roller 5 on the convex surface of the cam 4 moves in the horizontal direction. When the support leg 1 does not need to move laterally, the telescopic mechanism 11 can be reset by the start button. Under the linkage of the diagonal rod 9, the connecting rod 7 and the transmission shaft 3, the convex surface of the cam 4 gradually moves away from the ground until the load-bearing wheel 6 re-contacts the ground.

[0027] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
