Description

Technical Field

[0001] The utility model belongs to the technical field of forklift counterweight transfer frames, and more specifically, relates to a forklift counterweight transfer frame. Background Art

[0002] A forklift counterbalancer, also known as a forklift balancer or forklift top-mounted device, is a device used to increase the transport capacity and stability of a forklift. It can increase the forklift's load capacity beyond its rated weight, enabling it to safely handle large or heavy items. A forklift counterbalancer typically consists of an adjustable counterweight arm or bar that attaches to the forklift's forks and connects to the forklift body via a hydraulic or mechanical system.

[0003] The existing publication number CN221720430U discloses a forklift counterbalanced weight transfer frame. Although it has the effect of expanding the force area for compacting the goods by starting the drive motor and cooperating with the first pressure plate and the second pressure plate, it can also adjust the height of the first pressure plate by flipping the drive motor to facilitate the compaction of the goods.

[0004] Based on the above, the inventors found the following problems: However, this method relies solely on the friction between the first pressure plate, the second pressure plate and the top of the cargo to limit the position. When the top of some cargo is relatively smooth, it is easy for the cargo to slide directly out from the bottom of the first pressure plate and the second pressure plate. This limiting method is less effective. At the same time, the device requires manual adjustment of the drive motor. The forklift forks the cargo frequently, and manual adjustment each time is cumbersome.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a forklift counterweight transfer rack is provided in order to achieve a more practical purpose. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a forklift counterbalanced weight transfer frame to solve the problem that the current limiting method relies solely on the friction with the top of the cargo, resulting in poor effect of this limiting method.

[0007] The utility model provides a forklift counterweight transfer frame, which is achieved by the following specific technical means:

[0008] A forklift counterweight transfer frame includes a frame body, a lifting mechanism is provided in the middle of the frame body, a fork rod is provided on one side of the lifting mechanism, the frame body is U-shaped, a second servo motor is fixed on one side of the middle part of the top of the frame body, a second threaded rod is fixed to the power output end of the second servo motor, the outer wall of the second threaded rod is threadedly connected to the second threaded sleeve, one end of the second threaded sleeve is fixed to the first servo motor, the power output end of the first servo motor is fixed to the first threaded rod, the outer wall of the first threaded rod is threadedly connected to the first threaded sleeve, a connecting rod is fixed to the bottom of the first threaded sleeve, a limiting rod is fixed on one side of both ends of the connecting rod, a sleeve rod is fixed on the other side of both ends of the connecting rod, a telescopic rod is movably sleeved inside the sleeve rod, a sliding rod is fixed on one side of the telescopic rod, and the sliding rod is slidably connected to the frame body.

[0009] Furthermore, sliding grooves are provided on both sides of the inner wall of the frame, and two sliding rods are provided, and the two sliding rods are respectively slidably connected to the corresponding sliding grooves.

[0010] Furthermore, the second servo motor is located on a side of the top of the frame away from the fork rod, and the length of the second threaded rod is greater than half of the height of the frame.

[0011] Furthermore, the limiting rod is arranged in an L-shape, and the two limiting rods are respectively arranged directly above the tops of the two fork rods.

[0012] Furthermore, a second pressure sensor is fixed to the middle of the bottom of the limiting rod, and a first pressure sensor is fixed to the inner side wall of the bottom end of the limiting rod.

[0013] Furthermore, the first pressure sensor is electrically connected to the first servo motor, the second pressure sensor is electrically connected to the second servo motor, and the second servo motor and the first servo motor are both electrically connected to the lifting mechanism.

[0014] Furthermore, the bottom of the fork rod is arranged in an inclined shape with respect to the horizontal plane, and the bottom of the fork rod is arranged in a vertical shape with respect to the protruding end of the limiting rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the utility model, the first servo motor and the second servo motor rotate together, the second servo motor drives the limit rod to move down to the top of the cargo, and the first servo motor drives the limit rod to move right to fit with the top edge of the cargo. When the L-shaped limit rod fits with the top of the cargo, the bottom protruding end can be stuck on the top of the cargo, thereby achieving a better effect of limiting the cargo, and the low-friction cargo will still not fall.

[0017] 2. In the utility model, the start-up of the first servo motor and the second servo motor is controlled by the lifting mechanism. When the limit rod moves down to the top of the cargo, the second pressure sensor detects the pressure, and the second pressure sensor controls the stop of the second servo motor. When the limit rod moves to the right to fit the top edge of the cargo, the first pressure sensor senses the pressure and controls the stop of the first servo motor, thereby automatically controlling the first servo motor and the second servo motor, thereby achieving the effect of automatically controlling the limiting of the cargo.

[0030] Among them, there are sliding grooves 2 on both sides of the inner wall of the frame 1, and two sliding rods 3 are provided. The two sliding rods 3 are slidingly connected to the corresponding sliding grooves 2 respectively, and the two telescopic rods 4 are connected to the frame 1 through the two sliding rods 3, so that when the second servo motor 9 drives the connecting rod 6 to move downward, the sliding rod 3 can slide in the sliding groove 2 without affecting the movement of the connecting rod 6 and the limit rod 7.

[0031] Among them, the second servo motor 9 is located on the side of the top of the frame 1 away from the fork rod 11, and the length of the second threaded rod 12 is greater than half of the height of the frame 1. By starting the second servo motor 9 to drive the second threaded rod 12 to rotate, the second threaded sleeve 13 moves up and down, driving the first servo motor 14, the connecting rod 6 and the limit rod 7 to move up and down.

[0032] Among them, the limiting rod 7 is set in an L shape, and the two limiting rods 7 are respectively located directly above the top of the two fork rods 11. When the L-shaped limiting rod 7 is in contact with the top of the cargo, the bottom protruding end can be stuck on the top of the cargo.

The first servo motor 14 drives the first threaded rod 15 to rotate, driving the first threaded sleeve 8 to move laterally, and then driving the connecting rod 6 and the limit rod 7 to move laterally. When the limit rod 7 moves to the right to fit the top edge of the cargo, the first pressure sensor 16 senses pressure and controls the stop of the first servo motor 14, thereby achieving the effect of automatically controlling the first servo motor 14 and the second servo motor 9.
