[0028] Example:

[0029] See also Figure 1-5 A bidirectional reciprocating hoist comprises a shell 1, four guide rods 2 are fixedly connected to the upper and lower walls of the inner cavity of the shell 1, a plurality of reinforcing tubes 3 are fixedly connected to the ends of the four guide rods 2 close to each other, a driving mechanism 4 is fixedly connected to the bottom wall of the inner cavity of the shell 1, and a lifting mechanism 5 is slidably provided on the ends of the four guide rods 2 far away from each other.

[0030] This solution uses a driving mechanism 4 to simultaneously drive two lifting mechanisms 5 to reciprocate on the outer surfaces of the four guide rods 2 in the front and rear directions, thereby realizing vertical transportation of materials. During the transportation process, the materials can be lifted in the front and rear directions, thereby improving the transportation efficiency.

[0031] See also Figure 2-3 The driving mechanism 4 includes a pad 41, the lower end of the pad 41 is fixedly connected to the bottom wall of the inner cavity of the shell 1, the upper end of the pad 41 is fixedly connected to a motor 42, the output end of the motor 42 is fixedly connected to a pulley 43 through a coupling, the outer surface of the pulley 43 is meshedly connected to a transmission belt 44, the inner surface of the transmission belt 44 is meshedly connected to a driving component 45, the driving component 45 includes four support rods 451, the lower ends of the four support rods 451 are fixedly connected to the bottom wall of the inner cavity of the shell 1, the upper ends of the four support rods 451 are respectively fixedly connected to two positioning seats 452, the inner surfaces of the two positioning seats 452 are connected to the transmission rod 453 for rotation together, and the outer surface of the transmission rod 453 is fixedly connected to Two pulley threes 454 are connected, and the outer surfaces of the four pulley threes 454 are meshed and connected with the inner surface of the transmission belt two 46. The outer surface of the transmission rod 453 is fixedly connected to two pulley fours 455, and the outer surfaces of the two pulley fours 455 are meshed and connected with the inner surface of the transmission belt one 44. The outside of the driving component 45 is meshed and connected with another driving component 45. The two driving components 45 are meshed and connected with four transmission belts two 46 on the outside. The inner surfaces of the four transmission belts two 46 are meshed and connected with four pulley twos 47 on the inside. The four pulley twos 47 are fixedly connected with a connecting rod 48 at one end close to each other. The outer surfaces of the two connecting rods 48 are rotatably connected with a positioning plate 49.

[0032] This solution starts the motor 42, so that the pulley 1 43 drives the meshing pulley 1 43 to rotate under the action of the motor 42. The rotation of the pulley 1 43 will drive the transmission belt 1 44 to drive the pulley 4 455 located on the left side of the outer surface of the transmission rod 453 to rotate. The pulley 4 455 will cause the transmission rod 453 to rotate, which will cause another pulley 4 455 to rotate and drive another driving component 45 through another transmission belt 1 44. At this time, the four pulleys 3 454 will rotate, and with the cooperation of the outer surfaces of the four pulleys 2 47, the four transmission belts 2 46 can rotate on the outer surfaces of the four pulleys 3 454 and the four pulleys 2 47, thereby realizing the movement of the four transmission belts 2 46.

[0033] See also Figure 4-5 The lifting mechanism 5 includes two lifting frames 51, and the ends of the two lifting frames 51 close to each other are fixedly connected with a plurality of reinforcement rods 54. The rear ends of the two lifting frames 51 are fixedly connected with two sliding assemblies 52. The sliding assembly 52 includes a perforated plate 521, and the front end of the perforated plate 521 is fixedly connected with a slotted plate 522. The front end of the slotted plate 522 is provided with a vertical groove 523. The front end of the vertical groove 523 is fixedly connected with a toothed plate 524. The rear end of the toothed plate 524 is meshed with the inner surface of the transmission belt 2 46.

The rear ends of the two mounting rods 55 are fixedly connected with four sliding members 53. The inner surfaces of the four sliding members 53 are respectively slidably connected with the outer surfaces of the two guide rods 2 located on the front side.

[0034] The present solution is to pass the four transmission belts 2 46 through the front end of the vertical slot 523 and the rear end of the toothed plate 524. Since the rear end of the toothed plate 524 is meshedly connected with the inner surface of the transmission belt 2 46, the four transmission belts 2 46 will cooperate with the toothed plate 524 when moving downward, so that the perforated plate 521, the slotted plate 522 and the toothed plate 524 can move upward together under the action of the four transmission belts 2 46, and can drive the placement tray composed of two lifting frames 51 and a plurality of reinforcement rods 54 to move upward together. At the same time, it is guided by the sliding connection between the four sliding members 53 and the two guide rods 2 to avoid incorrect lifting position of the elevator.

[0035] Working principle: When the elevator is needed, the materials are placed on the placement trays composed of two lifting frames 51 and several reinforcement rods 54 in each direction of the front and rear chains, and then the motor 42 is started, so that the pulley 1 43 drives the meshing pulley 1 43 to rotate under the action of the motor 42, and the rotation of the pulley 1 43 will drive the transmission belt 1 44 to drive the pulley 4 455 located on the left side of the outer surface of the transmission rod 453 to rotate, and the pulley 4 455 will cause the transmission rod 453 to rotate, which will cause another pulley 455 to rotate and drive another driving component 45 through another transmission belt 1 44, and at this time, the four pulleys 3 454 will rotate, and with the cooperation of the outer surfaces of the four pulleys 2 47, the four transmission belts 2 46 can rotate on the outer surfaces of the four pulleys 3 454 and the four pulleys 2 47, so that the four transmission belts 2 4 6 moves, because the four transmission belts 2 46 pass through the front end of the vertical slot 523 and the rear end of the toothed plate 524, and the rear end of the toothed plate 524 is meshed and connected with the inner surface of the transmission belt 2 46, so the four transmission belts 2 46 will cooperate with the toothed plate 524 when moving downward, so that the perforated plate 521, the slotted plate 522 and the toothed plate 524 can move upward together under the action of the four transmission belts 2 46, which can drive the placement support plate composed of the two lifting frames 51 and the plurality of reinforcement rods 54 to move upward together. At the same time, the sliding connection between the four sliding members 53 and the two guide rods 2 is used for guidance to avoid the incorrect lifting position of the elevator, so that the material can be lifted upward. After lifting to the highest point and unloading the material, the motor 42 is reversed, so that the placement support plate composed of the two lifting frames 51 and the plurality of reinforcement rods 54 returns to the initial position for secondary lifting.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
