Technical Field

[0001] The utility model relates to the technical field of conveyors, and particularly relates to a lifting conveyor. Background Art

[0002] A conveyor is a mechanical device that drives a conveyor belt through a driving device to convey materials from a starting point to an ending point. The existing conveyor drives the conveyor belt through a driving device (such as an electric motor) to make the conveyor belt move on a certain route, thereby conveying materials from the starting point to the ending point. The movement of the conveyor belt is supported by idlers or rollers, and these components can bear the weight of the materials and ensure the smooth movement of the conveyor belt. However, due to limitations in height, cost, or site scope, this type of conveyor cannot perform vertical drop conveying, and its conveying function is relatively single, unable to well meet the need for vertical cargo transportation.

Detailed implementation manners

[0026] The principles and features of the present utility model are described below with reference to the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0027] As Figure 1As shown in the figure, a lifting conveyor includes a base assembly 1, a scissor lift assembly 2, a slider support assembly 3, an upper frame assembly 4, a conveying assembly 5, and a driving assembly 6. The lower end of the scissor lift assembly 2 is slidably disposed on the base assembly 1 through the slider support assembly 3. The upper end of the scissor lift assembly 2 is slidably connected to the upper frame assembly 4 through an ear seat bearing assembly 7. The conveying assembly 5 is disposed on the upper frame assembly 4. The driving assembly 6 is located on the base assembly 1 and is connected to the slider support assembly 3 in a mating manner. By driving the slider support assembly 3 to slide through the driving assembly 6, the up-and-down opening and closing movement of the scissor lift assembly 2 is realized. Under the opening and closing movement, the overall up-and-down vertical lifting of the upper frame assembly 4 and the conveying assembly 5 is driven. When reaching the designated position, the goods are horizontally transported through the conveying assembly 5. Thus, both the vertical lifting and lowering of the goods and the horizontal conveying function are realized, and the entire process can be electrically controlled and can be automatically, quickly and effectively completed. The electrical control system can adopt a PLC control system.

[0028] As Figure 2 shown in the figure, the base assembly 1 includes a base frame 10, linear slide rails 11 and ear seats 12 respectively disposed on both sides of the base frame 10, and a support assembly 13 disposed in the middle of the base frame 10 for mounting the driving assembly 6. One end of the lower part of the scissor lift assembly 2 is in sliding fit with the linear slide rail 11 through the slider support assembly 3, and the other end is hingedly disposed on the ear seat 12. The linear slide rail 11 is installed on the base frame 10 through bolts and is in cooperation with the slider 32 on the slider support assembly 3 to guide the movement of the scissor lift assembly 2. As Figure 3 shown in the figure, the slider support assembly 3 includes a cross beam 30, hinge seats 31 respectively disposed at both ends of the cross beam 30, and sliders 32 disposed at the lower ends of the hinge seats 31 and in sliding fit with the linear slide rail 11. A bushing 33 cooperating with the driving assembly 6 is disposed on the cross beam 30. The cross beam 30 serves as the connecting body of the scissor lift assemblies 2 on both sides. The driving assembly 6 pushes the cross beam 30, so that the sliders 32 on both sides of the cross beam 30 move along the linear slide rail 11, and then drives the scissor lift assembly 2 disposed on the hinge seats 31 to perform an opening and closing movement.

[0029] As Figure 4As shown in the figure, the driving assembly 6 includes a driving motor 60 arranged on the base frame 10, a ball screw 62 arranged at the output end of the driving motor 60 through a coupling 61, and a nut 63 arranged on the ball screw 62 and connected to the shaft sleeve 33. The ball screw 62 is arranged on the base frame 10 through a bearing bracket. The coupling 61 is used to connect the motor and the ball screw, and the bearing 71 seat assembly is used to transmit torque. The ball screw is connected to the slider support assembly 3 to transmit torque to the movement of the scissor fork assembly 2. During use, the driving motor 60 drives the ball screw 62 to rotate. During the rotation of the ball screw 62, the nut 63 is driven to move, thereby pushing the cross beam 30 to move. The sliders 32 on both sides of the cross beam 30 move along the linear slide rail 11, thereby driving the scissor fork assembly 2 on the hinge seat 31 provided with the slider 32 to perform an opening and closing movement. Therefore, when the ball screw rotates, the slider 32 on the slider support assembly 3 moves linearly in cooperation with the slide rail 41 on the base assembly 1, enabling the opening and closing movement of the scissor fork assembly 2 to achieve the lifting of the upper frame part.

[0030] As Figure 5 shown in the figure, the upper frame assembly 4 includes an upper frame 40, and slide rails 41 and double-ear seats 42 respectively arranged at the bottoms of both sides of the upper frame 40. One end of the upper part of the scissor fork assembly 2 is slidably connected to the slide rail 41 through an ear seat bearing assembly 7, and the other end is hinged to the double-ear seat 42. As Figure 6 shown in the figure, the ear seat bearing assembly 7 includes an ear seat body 70, a bearing 71 arranged on the ear seat body 70, and a slider 32 arranged below the ear seat body 70 and slidably matched with the slide rail 41. The ear seat body 70 is arranged on the upper frame 40.

[0031] As Figure 7 shown in the figure, the scissor fork assembly 2 includes two groups of first fork plates 20 with ends connected by a rotating shaft and a second fork plate 21 rotatably connected between the two first fork plates 20. The two first fork plates 20 form an activity cavity. The second fork plate 21 can rotate in the activity cavity with the middle part of the first fork plate 20 as a fulcrum to achieve opening and closing. The first fork plate 20 and the second fork plate 21 are connected in an X structure between the base assembly 1 and the upper frame assembly 4.

[0032] As Figure 8As shown in the figure, the conveying assembly 5 includes a mounting frame 50, a sprocket-type conveyor 51 disposed on the mounting frame 50, and a baffle assembly disposed on the mounting frame 50. The baffle assembly is connected to the air source assembly 14 disposed on the base assembly 1, and the mounting frame 50 is disposed on the upper frame assembly 4. The sprocket-type conveyor 51 adopts an existing structure, which includes a motor, a sprocket, a shaft tensioner, a transmission chain, a bearing 71, a conveyor chain support assembly, etc., mounted on the mounting frame 50 to provide power for conveying goods. The baffle assembly includes a cylinder 18 and a baffle 19 disposed on the telescopic end of the cylinder 18. The cylinder 18 is connected to the air source assembly 14. The air source assembly 14 includes a pressure reducing filter and a solenoid valve. The lifting of the baffle 19 is driven by the telescopic movement of the cylinder 18, so that the tray can accurately stop at the target position.

[0033] A travel switch assembly 15 and an induction assembly 16 are respectively disposed on the base assembly 1, and a sensor assembly 17 is disposed on the upper frame assembly 4. The travel switch assembly 15 determines the target height of the lifting conveyor for rising and falling through the corresponding induction assembly 16, and determines whether the tray is in place through the sensor assembly 17. The travel switch assembly 15 and the induction assembly 16 adopt existing structures. Among them, the travel switch assembly 15 includes an aluminum profile, a photoelectric switch, a travel switch, a mounting plate, etc. The induction plate assembly includes a mounting plate, an induction plate, and a collision plate. The photoelectric and travel switches determine the target height of the lifting conveyor for rising and falling through the corresponding induction plate and collision plate.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
