Description

Technical Field

[0001] This utility model relates to a gantry-type lifting and conveying device. Background Technology

[0002] Conveyors are needed in many industries such as textiles, food, packaging, and spraying. In some production workshops, the length and height of the conveyor may need to be adjusted due to the layout of the workshop and the process flow. However, the existing conveyor structure is relatively fixed and not easy to adjust, and it is not possible to adjust both horizontally and vertically at the same time.

[0003] Most lifting and conveying equipment that can achieve vertical lifting uses cylinders, hydraulic cylinders, and lead screws placed in the middle of the gantry as the main driving force for lifting. This layout will cause the forces at both ends of the roller conveyor to be unbalanced and is not suitable for lifting heavy objects.

[0004] In view of this, it is necessary to improve the existing gantry lifting conveyor equipment to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gantry-type lifting and conveying device to solve the problems of unbalanced forces at both ends during lifting and difficulty in lifting heavy items in existing equipment.

[0006] To achieve the above objectives, this utility model provides a gantry-type lifting and conveying device. The gantry-type lifting and conveying device includes a gantry frame, chains disposed on both sides of the gantry frame, a drive assembly for driving the chains to rotate, guide rails extending along the height direction disposed on both sides of the gantry frame, a lifting frame slidable relative to the guide rails, and chain connecting plates fixedly disposed on both sides of the lifting frame. The chain connecting plates are respectively fixed to the chains on both sides. The drive assembly includes a drive motor, a drive gear connected to the output shaft of the drive motor, two driven gears meshing with both sides of the drive gear, and two first sprockets coaxially disposed with the two driven gears. The first sprockets rotate to drive the chain transmission. The lifting frame is provided with multiple rollers, roller chains connected to the multiple rollers, a roller motor for driving the roller chains and the roller transmission, and a slider slidably engaged with the guide rails.

[0007] As a further improvement of this utility model, the gantry lifting and conveying equipment also includes guide rail pads fixed on both sides of the gantry frame, the guide rail pads extending toward one side of the lifting frame, and the guide rails fixed on the guide rail pads.

[0008] As a further improvement of this utility model, the gantry frame includes a top frame and side frames extending downward from both ends of the top frame, and the guide rail and the guide rail pad are disposed on the side frames.

[0009] As a further improvement of this utility model, the drive assembly also includes a motor frame, which is fixed on the top frame and located in the middle of the top frame.

[0010] As a further improvement of this utility model, the chain includes a first chain body extending along the side frame and a second chain body connected to the first chain body and extending along the top frame, wherein the first sprocket is disposed at the end of the second chain body away from the first chain body.

[0011] As a further improvement of this utility model, the drive assembly also includes a second sprocket fixed to the top of the side frame and a third sprocket fixed to the bottom of the side frame, with the first sprocket fixed to the top frame.

[0012] As a further improvement of this utility model, the gantry frame also includes a base frame that is fixedly connected to the bottom of the side frame.

[0013] As a further improvement of this utility model, the gantry frame also includes casters disposed at the bottom of the base frame.

[0014] The beneficial effects of this utility model are as follows: The gantry-type lifting conveyor of this utility model, by setting a drive motor to drive the chains on both sides for transmission, can reduce costs and improve the stability and balance of lifting, and can achieve the lifting of heavy materials; by setting guide rail pads, interference between the lifting frame and the chain can be avoided.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figures 1 to 4 As shown, the gantry-type lifting conveyor 100 of this utility model includes a gantry frame 1, chains 2 disposed on both sides of the gantry frame 1, a drive assembly 3 for driving the chains 2 to rotate, guide rails 4 extending along the height direction disposed on both sides of the gantry frame 1, a lifting frame 5 slidable relative to the guide rails 4, chain connecting plates 6 fixedly disposed on both sides of the lifting frame 5, and guide rail pads 7 fixed on both sides of the gantry frame 1.

[0024] The gantry frame 1 includes a top frame 11, side frames 12 extending downward from both ends of the top frame 11, a base frame 13 fixedly connected to the bottom of the side frames 12, and casters 14 disposed at the bottom of the base frame 13.

[0025] In this embodiment, the gantry frame 1 serves as a support, the casters 14 can drive the gantry lifting and conveying equipment 100 to move, and the casters 14 have a self-locking structure.

[0026] In this embodiment, the chain 2 includes a first chain body 21 extending along the side frame 12 and a second chain body 22 connected to the first chain body 21 and extending along the top frame 11, and the first chain body 21 and the second chain body 22 are arranged perpendicularly. In this embodiment, each chain 2 is L-shaped.

[0027] In this embodiment, the guide rail pad 7 extends toward the lifting frame 5, and the guide rail 4 is fixed on the guide rail pad 7.

[0028] The guide rail 4 and the guide rail pad 7 are disposed on the side frame 12. In this embodiment, each chain 2 is arranged to form a ring, and the guide rail 4 and the guide rail pad 7 are disposed within the first chain body 21. The guide rail pad 7 can keep the guide rail 4 away from the side frame 12, thus avoiding interference between the guide rail 4 and the chain 2.

[0029] The chain connecting plate 6 is fixed to the chains 2 on both sides respectively, so that when the chains 2 rotate, the chain connecting plate 6 can drive the lifting frame 5 to move.

[0030] The lifting frame 5 is provided with multiple rollers 51, roller chains 52 connected to the multiple rollers 51, roller motors 53 for driving the roller chains 52 and the rollers 51, connecting blocks 54, and sliders 55 that can slide with the guide rail 4.

[0031] In this embodiment, the chain connecting plate 6 is fixedly connected to the connecting block 54. The connecting block 54 extends from both sides of the lifting frame 5 toward the gantry frame 1.

[0032] The roller motor 53 is a motor used to drive the roller 51 to rotate. The roller motor 53 can drive the roller 51 to rotate via chain drive or belt drive. In this embodiment, chain drive is used to convey the material on the roller 51. In this embodiment, the axial direction of the roller 51 is perpendicular to the direction of the gantry frame 1.

[0033] Both sides of the lifting frame 5 are provided with sliders 55, which extend vertically and can move up and down vertically relative to the guide rail 4.

[0034] The drive assembly 3 includes a drive motor 31, a drive gear 32 connected to the output shaft of the drive motor 31, two driven gears 33 meshing with both sides of the drive gear 32, two first sprockets 34 coaxially arranged with the two driven gears 33, a second sprocket 35 fixed to the top of the side frame 12, a third sprocket 36 fixed to the bottom of the side frame 12, and a motor frame 37.

[0035] The motor frame 37 is fixed to the top frame 11 and located in the middle of the top frame 11, and the drive motor 31 is fixedly mounted on the motor frame 37. In this embodiment, the chains 2 on both sides are set as L-shaped, and the drive motor 31 is set in the middle, so that one drive motor 31 can drive the chains 2 on both sides to work at the same time.

[0036] Furthermore, the driven gears 33 on both sides mesh with the driving gear 32 simultaneously, which ensures that the chains 2 on both sides are subjected to more balanced forces, making them less prone to tipping over and more suitable for lifting heavy objects.

[0037] The first sprocket 34 is fixed to the top frame 11. Furthermore, the first sprocket 34 is located at the end of the second chain 22 away from the first chain 21. The first sprocket 34 rotates to drive the chain 2.

[0038] The second sprocket 35 and the third sprocket 36 act as driven wheels, providing auxiliary transmission and controlling the direction of the chain 2.

[0039] The working process of the gantry-type lifting conveyor 100 of this utility model is as follows: The material is placed on the lifting frame 5, and the drive motor 31 is controlled to drive the drive gear 32 and the driven gear 33 to rotate, which in turn drives the first sprocket 34 and the chain 2 on both sides to rotate. The lifting frame 5 slides upward along the slide rail to realize the lifting of the lifting frame 5. When it is lifted to a predetermined height, the drive motor 31 stops working, the roller motor 53 works, drives the roller 51 to rotate, and conveys the material to the next work station. Then the drive motor 31 reverses and controls the lifting frame 5 to lower and reset.

[0040] The gantry-type lifting conveyor 100 of this utility model uses a drive motor 31 to drive the chains 2 on both sides for transmission. This can reduce costs, improve the stability and balance of lifting, and enable the lifting of heavy materials. By setting guide rail pads 7, interference between the lifting frame 5 and the chains 2 can be avoided. The gantry-type lifting conveyor 100 is convenient to use and has low cost.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
