Description

A material handling and lifting device Technical Field

[0001] This utility model relates to the field of material handling technology, specifically a material handling and lifting device. Background Technology

[0002] Material lifting and transportation refers to the process of raising materials from a lower to a higher position, typically involving the use of various mechanical equipment to achieve vertical transport of materials. This mode of transportation is widely used in various fields such as industrial production and warehousing logistics, aiming to improve production efficiency and logistics efficiency.

[0003] For example, the authorization announcement number "CN215160598U" describes a material lifting device that improves the stability of the pallet during the lifting process when the goods are lifted to a designated height. The limiting holes and positioning holes are fixed by fixing pins, which can prevent the pallet from falling accidentally during the loading and unloading of goods. Existing material lifting devices use a drive motor to pull the horizontal pallet to transport goods to a higher position. However, the transport of goods can only be completed through one channel. That is to say, after the goods are lifted upward, only one-way feeding or one-way picking can be completed. It is difficult to complete the process of simultaneous feeding or picking, so repeated transport operations are required, which prolongs the material lifting and handling time. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem of excessively long cargo handling time in existing material lifting devices, and to propose a material handling and lifting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a material handling and lifting device, including a base, uprights and crossbeams. The uprights are fixedly installed on the top of the base, and the crossbeams are fixedly connected to the inner sides of the tops of the two uprights. The inner side of the uprights is provided with a bidirectional material feeding structure, the two sides of the uprights are provided with a multi-stage material handling structure, and the top of the uprights is provided with a material lifting and traction structure.

[0007] Preferably, the bidirectional material feeding structure includes a lifting plate and chutes. Multiple chutes are fixedly formed on both sides of the outer wall of the uprights. The lifting plate is slidably connected to the inside of the two uprights. A guide block is slidably connected to the inner side of the chutes. A connecting plate is fixedly connected to one side of the guide block. The other ends of the two connecting plates are fixedly connected to both sides of the lifting plate. A feeding channel is fixedly installed on the inner side of the lifting plate. Multiple feeding rollers are rotatably connected above the feeding channel. A drive motor is fixedly connected to one end of each feeding roller.

[0008] Preferably, multiple drive motors are fixedly installed on both sides inside the lifting plate, and the two feeding channels are arranged in parallel relative to each other.

[0009] Preferably, the multi-stage material handling structure includes a feeding bracket and a conveying bracket. The feeding bracket is fixedly connected to the ground on one side of the upright, and a feeding conveyor belt is fixedly installed at the top of the feeding bracket. Multiple conveying brackets are fixedly connected to the ground on the other side of the upright, and a grading plate is fixedly connected to the inner side of the multiple conveying brackets. A discharging conveyor belt is rotatably connected to the inner side of the multiple grading plates.

[0010] Preferably, one side of the grading plate is movably connected to one end of the feeding channel, and the end of the feeding conveyor belt is movably connected to the other end of the feeding channel.

[0011] Preferably, the material lifting and traction structure includes sliding rails and traction machines. Two sliding rails are fixedly connected to both sides of the outer wall of the upright. Counterweights are slidably connected to the inner sides of the two sliding rails. Two traction machines are fixedly installed at the top of the upright. Traction cables are fixedly connected to the lower end of the traction machines. One end of the traction cable is fixedly connected to the counterweight, and the other end of the traction cable is fixedly connected to both sides of the top of the lifting plate.

[0012] The material handling and lifting device proposed in this utility model has the following advantages: the goods are transported on the feeding conveyor belt below to the feeding roller on one side of the feeding channel, and then the lifting plate is pulled up by the traction machine. The drive motors inside the two feeding channels rotate in opposite directions. In this way, the drive motor will drive the feeding roller inside one side of the feeding channel to move the goods to the unloading conveyor belt of the grading plate. The unloading conveyor belt can also choose to transport the goods in the opposite direction to the other side of the feeding channel. Therefore, it is possible to realize the operation of feeding and unloading goods at the same time, saving material handling time. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please refer to Figures 1-6. In this embodiment, a material handling and lifting device includes a base 1, a vertical frame 2, and a crossbeam 3. The vertical frame 2 is fixedly installed on the top of the base 1. The base 1 is firmly installed on the ground of the logistics workshop by multiple anchor bolts. The crossbeam 3 is fixedly connected to the inner side of the top of the two vertical frames 2. The crossbeam 3 is made of high-strength metal steel. The crossbeam 3 is welded to the top of the base 1 in conjunction with the vertical vertical frame 2. The vertical frame 2 is the main structure of the entire material handling and lifting device. The inner side of the vertical frame 2 is provided with a bidirectional material feeding structure 4. The two sides of the vertical frame 2 are provided with a multi-stage material handling structure 5. The top of the vertical frame 2 is provided with a material lifting and traction structure 6.

[0023] The bidirectional material feeding structure 4 includes a lifting plate 41 and chutes 47. Multiple chutes 47 are fixedly formed on both sides of the outer wall of the upright 2. The lifting plate 41 is slidably connected to the interior of the two uprights 2. The lifting plate 41 is made of relatively sturdy stainless steel, enabling it to bear relatively heavy goods for lifting operations. Guide blocks 46 are slidably connected to the inner side of the chutes 47. A connecting plate 45 is fixedly connected to one side of the guide block 46, connecting the middle lifting plate 41 to the two guide blocks 46. The chutes 47 are vertically carved on both sides of the upright 2, allowing the guide blocks 46 to slide up and down inside the chutes 47, conveniently limiting the position of the middle lifting plate 41 and preventing deviation during lifting. The other ends of the two connecting plates 45 are fixedly connected to both sides of the lifting plate 41. Two feeding channels 42 are fixedly installed on the inner side of the lifting plate 41, located on both sides of the lifting plate 41. Multiple feeding rollers 44 are rotatably connected side by side. The ends of the feeding rollers 44 are driven by a drive motor 43 to rotate. In this way, the goods are transported on the feeding conveyor belt 52 below to the feeding rollers 44 on one side of the feeding channel 42. Then, the lifting plate 41 is pulled up by the traction machine 62. The lifting plate 41 can rise to the end of the designated grading plate 54 to complete the docking. At this time, the power is connected and the drive motor 43 is started. The drive motors 43 inside the two feeding channels 42 rotate in opposite directions. In this way, the drive motor 43 will drive the rotating feeding rollers 44 inside one feeding channel 42 to move the goods to the unloading conveyor belt 55 of the grading plate 54. The unloading conveyor belt 55 can also choose to transport the goods in the opposite direction to the other side of the feeding channel 42. Therefore, the operation of feeding and unloading goods can be carried out at the same time. Multiple feeding rollers 44 are rotatably connected above the feeding channel 42. One end of the multiple feeding rollers 44 is fixedly connected to the drive motor 43.

[0024] Multiple drive motors 43 are fixedly installed on both sides inside the lifting plate 41. The drive motors 43 are servo motors, and the two feeding channels 42 are arranged in parallel relative to each other.

[0025] The multi-stage material handling structure 5 includes a loading support 51 and a conveying support 53. The loading support 51 is fixedly connected to the ground on one side of the upright 2. The loading support 51 is made of aluminum alloy and has a relatively low height, making it convenient for workers to place the goods to be lifted onto the loading conveyor belt 52. The loading conveyor belt 52 is fixedly installed at the top of the loading support 51. The loading conveyor belt 52 is a common type of conveyor belt structure used in logistics. When powered on, it uses rotating rollers to move the goods. The end of the loading conveyor belt 52 can be connected to one end of the lifting plate 41, so that the goods can be transported to the lifting plate. Above 41, multiple material conveying supports 53 are fixedly connected to the ground on the other side of the upright 2. The material conveying supports 53 are designed as multiple vertical aluminum alloy uprights. Multiple horizontal grading plates 54 are installed at equal intervals on the inner side of the material conveying supports 53. The unloading conveyor belt 55 is installed on the inner side of the grading plate 54 to guide the goods to be received and sent away. Therefore, the goods on the lifting plate 41 can be selectively lifted to the ends of the grading plates 54 at different heights to complete the docking, which facilitates the guidance of the goods to higher places. The grading plates 54 are fixedly connected to the inner side of the multiple material conveying supports 53, and the unloading conveyor belt 55 is rotatably connected to the inner side of the multiple grading plates 54.

[0026] One side of the grading plate 54 is movably connected to one end of the feeding channel 42, and the end of the feeding conveyor belt 52 is movably connected to the other end of the feeding channel 42.

[0027] The material lifting traction structure 6 includes sliding rails 61 and traction machines 62. Two sliding rails 61 are fixedly connected to both sides of the outer wall of the upright 2. The sliding rails 61 can limit the vertical sliding position of the counterweight 63. The counterweight 63 is slidably connected to the inner side of the two sliding rails 61. The counterweight 63 is made of solid metal steel with weight. Two traction machines 62 are fixedly installed at the top of the upright 2. The traction machine 62 is a relatively mature existing technology. The traction machine 62 can be composed of a motor, brake, coupling, gearbox, traction sheave, frame and guide wheel. The traction machine 62 is mainly responsible for lifting or lowering the lower lifting plate 41 by the friction between the traction cable 64 and the pulley. The lower end of the traction machine 62 is fixedly connected to the traction cable 64. One end of the traction cable 64 is fixedly connected to the counterweight 63, and the other end of the traction cable 64 is fixedly connected to both sides of the top of the lifting plate 41.

[0028] Working principle:

[0029] Material handling and lifting devices are installed inside cargo logistics workshops to lift and move goods from lower to higher levels using vertical frames.

[0030] The lifting plate 41 is made of robust stainless steel, enabling it to support heavy loads for lifting operations. A connecting plate 45 connects the middle lifting plate 41 to the guide blocks 46 on both sides. A chute 47 is vertically carved into both sides of the upright 2, allowing the guide blocks 46 to slide up and down within the chute 47, effectively limiting the position of the middle lifting plate 41 and preventing displacement during lifting. Two feeding channels 42 are provided on both sides of the lifting plate 41. Multiple feeding rollers 44 are rotatably connected side-by-side on each feeding channel 42. The ends of the feeding rollers 44 are driven by a drive motor 43 to rotate, thus conveying the goods below. The goods are conveyed on the conveyor belt 52 to the feeding roller 44 on one side of the feeding channel 42. Then, the traction machine 62 pulls the lifting plate 41 to rise. The lifting plate 41 can rise to the end of the designated grading plate 54 to complete the docking. At this time, the power supply is connected and the drive motor 43 is started. The drive motors 43 inside the two feeding channels 42 rotate in opposite directions. In this way, the drive motor 43 will drive the feeding roller 44 inside one feeding channel 42 to rotate to move the goods onto the unloading conveyor belt 55 of the grading plate 54. The unloading conveyor belt 55 can also choose to transport the goods in the opposite direction to the other side of the feeding channel 42. Therefore, it is possible to perform the operation of feeding and unloading goods at the same time.

[0031] The loading support 51 is made of aluminum alloy and is relatively low in height, making it convenient for workers to place the goods to be lifted onto the loading conveyor belt 52. The loading conveyor belt 52 is a common type of conveyor belt structure used in logistics. When powered on, it can use rotating rollers to move the goods. The end of the loading conveyor belt 52 can be connected to one end of the lifting plate 41, so that the goods can be transported above the lifting plate 41. The material handling support 53 is designed with multiple vertical aluminum alloy poles. The unloading conveyor belt 55 is installed inside the grading plate 54 to guide the goods to be received and sent away. Therefore, the goods on the lifting plate 41 can be selectively lifted to the end of the grading plate 54 at different heights to complete the connection, which facilitates the guidance of the goods to different heights.

[0032] The sliding track 61 can limit the vertical sliding position of the counterweight 63. The counterweight 63 is made of solid metal steel with weight. The traction machine 62 is a relatively mature existing technology at present. The traction machine 62 can be composed of a motor, brake, coupling, gearbox, traction sheave, frame and guide wheel. The traction machine 62 is mainly responsible for raising or lowering the lower lifting plate 41 by the friction between the traction cable 64 and the pulley.
