Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, and in particular to an adjustable hoist. Background Technology

[0002] In warehousing and logistics, manufacturing, and construction, hoists are core equipment for vertical material transportation, and their height adjustment capability directly affects operational efficiency and adaptability.

[0003] Current mainstream hoist height adjustment solutions have significant drawbacks: most traditional hoists adopt a fixed stroke design, which can only achieve the lifting and lowering of preset heights. For example, in warehouse scenarios, when facing different height shelves such as 1.2m, 1.8m, and 2.5m, it is necessary to replace the hoist with the corresponding specification or use a forklift for secondary transfer, which makes the operation process cumbersome, time-consuming, and labor-intensive, reducing production efficiency. Therefore, an adjustable hoist is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable hoist.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable hoist includes a connecting plate. A first bracket and a second bracket are fixedly connected to the four corners of the connecting plate. Slide grooves are formed on the inner walls of both sides of the first bracket. Slide plates are installed inside the first and second brackets. Conveyor platforms are fixedly connected to the top two sides of the slide plates. A lifting mechanism, including a servo motor, is installed inside the top of the first bracket and fixedly connected to the top of the first bracket. An adjustment mechanism, including a bidirectional motor, is installed inside the second bracket and fixedly connected to the inner wall of the top center of the second bracket. Connecting rods are fixedly connected to the output ends of the bidirectional motor on both sides. Support blocks are fixedly connected to the inner walls of the top two sides of the second bracket, and the support blocks are rotatably connected to the connecting rods.

[0006] As a further embodiment of this utility model: the ends of the connecting rods on both sides of the bidirectional motor are respectively fixedly connected to bevel gears, the inner walls on both sides of the bracket are respectively provided with limiting grooves, the inner walls at the bottom of the limiting grooves on both sides of the bidirectional motor are respectively rotatably connected to screws, and the top ends of the screws on both sides of the bracket are rotatably connected to the inner walls at the top of both sides of the bracket.

[0007] As a further embodiment of this utility model: bevel gears are fixedly connected to the top surfaces of the screws on both sides of the bracket two, and the bevel gears two mesh with the bevel gear one.

[0008] As a further embodiment of this utility model: the lower surfaces of the screws on both sides of the second bracket are respectively fixedly connected to limit blocks, the limit blocks are slidably connected to the limit grooves, and a sliding plate is fixedly connected to the opposite side of the limit blocks on both sides of the second bracket, the sliding grooves are also slidably connected to the two sides of the sliding plate.

[0009] As a further embodiment of this utility model: the output end of the servo motor is fixedly connected to a worm gear, and the inner walls on both sides of the top of the bracket are rotatably connected to rotating rods. A worm wheel is fixedly connected to the surface of the rotating rod, and the worm wheel meshes with the worm gear.

[0010] As a further embodiment of this utility model: a rope is sleeved on the surface of the rotating rod near the worm gear, the end of the rope extends to the bottom of the bracket, and the end of the rope is fixedly connected to the top side of the slide plate.

[0011] As a further improvement of this utility model, a controller is fixedly connected to one side of the bracket.

[0012] Compared with the prior art, this utility model provides an adjustable hoist, which has the following beneficial effects: This adjustable hoist features a lifting mechanism. During operation, the operator simultaneously starts a servo motor. The servo motor's output drives a worm gear to rotate, which in turn drives a meshing worm wheel. The worm wheel then drives a rotating rod, which in turn drives a rope to retract the coil. The rope then moves one side of a connected slide plate up and down, thereby moving the two conveyor platforms at the top up and down. This motion is identical to that of two screws driven by a bidirectional motor. This allows for adjustment of the rack height, saving time and effort and improving production efficiency.

[0013] This adjustable hoist, equipped with an adjustment mechanism, allows the operator to start a bidirectional motor. The two outputs of the bidirectional motor drive the connected bevel gear one to rotate, which in turn drives the meshing bevel gear two to rotate. The two bevel gears two then drive the connected screws to rotate, and the two screws drive the connected limit blocks to slide up and down on the inner wall of the limit groove. It eliminates the need to replace the hoist with a corresponding specification or to use a forklift for secondary transfer, making the operation process simple.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0020] An adjustable hoist, such as Figure 1 , Figure 2 , Figure 3 and Figure 2As shown, the system includes a connecting plate 1, with bracket 1 2 and bracket 2 7 fixedly connected to the four corners of the connecting plate 1. Slide grooves 3 are provided on the inner walls of both sides of bracket 1 2. Slide plates 4 are installed inside bracket 1 2 and bracket 2 7. Conveyor platforms 5 are fixedly connected to the top sides of slide plates 4. A lifting mechanism 6 is installed inside the top of bracket 1 2, including a servo motor 601, which is fixedly connected to the top of bracket 1 2. An adjustment mechanism 9 is installed inside bracket 2 7, including a bidirectional motor 901, which is fixedly connected to the inner wall of the top center of bracket 2 7. Connecting rods 903 are fixedly connected to the output ends of both sides of the bidirectional motor 901. Support blocks 902 are fixedly connected to the inner walls of the top sides of bracket 2 7, and the support blocks 902 are rotatably connected to the connecting rods 903.

[0021] In order to achieve corresponding height adjustment according to the different heights of the shelves, such as Figure 1 , Figure 4 and Figure 5 As shown, bevel gear 904 is fixedly connected to the ends of the connecting rods 903 on both sides of the bidirectional motor 901. Limiting grooves 908 are respectively opened on the inner walls of both sides of the bracket 7. Screws 905 are rotatably connected to the inner walls of the bottom of the limiting grooves 908 on both sides of the bidirectional motor 901. The top ends of the screws 905 on both sides of the bracket 7 are rotatably connected to the inner walls of the top of both sides of the bracket 7.

[0022] The top surfaces of the screws 905 on both sides of the bracket 2 7 are respectively fixedly connected to bevel gear 2 907, which meshes with bevel gear 1 904.

[0023] Limiting blocks 906 are fixedly connected to the lower surfaces of the screws 905 on both sides of bracket 2 7. The limiting blocks 906 are slidably connected to the limiting grooves 908. A sliding plate 4 is fixedly connected to the opposite side of the limiting blocks 906 on both sides of bracket 2 7. The sliding grooves 3 are also slidably connected to the two sides of the sliding plate 4.

[0024] The operator starts the bidirectional motor 901. The two output ends of the bidirectional motor 901 drive the connected bevel gear 904 to rotate. The bevel gear 904 drives the meshing bevel gear 907 to rotate. The two bevel gears 907 drive the connected screws 905 to rotate. The two screws 905 drive the connected limit blocks 906 to slide up and down on the inner wall of the limit groove 908. It does not require changing to a corresponding specification hoist or using a forklift for secondary transfer, and the operation process is simple.

[0025] To better coordinate with screw 905 and make the sliding plate 4 more stable during lifting and lowering, such as... Figure 1 , Figure 2 and Figure 3As shown, the output end of the servo motor 601 is fixedly connected to the worm gear 602, and the inner walls on both sides of the top of the bracket 2 are rotatably connected to the rotating rod 603. The surface of the rotating rod 603 is fixedly connected to the worm wheel 604, which meshes with the worm gear 602.

[0026] A rope 605 is sleeved on the surface of the rotating rod 603 near the worm gear 604. The end of the rope 605 extends to the bottom of the bracket 2 and is fixedly connected to the top side of the slide plate 4.

[0027] During operation, the operator synchronously starts the servo motor 601. The output end of the servo motor 601 drives the worm gear 602 to rotate, which in turn drives the meshing worm wheel 604 to rotate. The worm wheel 604 drives the rotating rod 603 to rotate, which in turn drives the rope 605 to rewind the coil. The rope 605 drives one side of the connected slide plate 4 to move up and down, which in turn drives the two conveyor platforms 5 at the top to move up and down. The movement process is the same as that of the two screws 905 driven by the bidirectional motor 901. This allows for the adjustment of the shelf to different heights, saving time and effort and improving production efficiency.

[0028] A controller 8 is fixedly connected to one side of bracket 2.

[0029] The controller 8 is electrically connected to the servo motor 601 and the bidirectional motor 901 via wires, and the controller 8 controls the servo motor 601 and the bidirectional motor 901 to start and stop simultaneously.

[0030] Working principle: During operation, the material to be conveyed is placed on top of the two conveyor platforms 5. The operator controls the servo motor 601 and the bidirectional motor 901 to start simultaneously via the controller 8. The two output ends of the bidirectional motor 901 drive the connected bevel gear 904 to rotate. The bevel gear 904 drives the meshing bevel gear 907 to rotate. The two bevel gears 907 drive the connected screws 905 to rotate. The two screws 905 drive the connected limit blocks 906 to slide up and down on the inner wall of the limit groove 908. At the same time, the output end of the servo motor 601 drives the worm gear 602 to rotate. The worm gear 602 drives the meshing worm wheel 604 to rotate. The worm wheel 604 drives the rotating rod 603 to rotate. The rotating rod 603 drives the rope 605 to rewind. The rope 605 drives one side of the connected slide plate 4 to move up and down, thereby driving the two conveyor platforms 5 on top to move up and down. The movement process is the same as that of the two screws 905 driven by the bidirectional motor 901, which can convey the material on the two conveyor platforms 5 to the designated position.
