Description

An electric lifting rack with adjustable pallet height Technical Field

[0001] This utility model belongs to the field of warehouse racking technology, and relates to an electric lifting rack, especially an electric lifting rack with adjustable pallet height. Background Technology

[0002] In existing warehouse racking systems, the vertical space is often wasted due to the fixed height of the pallets. Adjusting the pallet height to fully utilize this space requires removing the goods from the pallet, detaching it from the rack, reinstalling it at the desired height, and finally replacing the goods. This method is time-consuming, labor-intensive, slow, and inefficient. Therefore, it is necessary to provide a racking system that allows for convenient pallet height adjustment. Summary of the Invention

[0003] The purpose of this utility model is to provide an electric lifting rack with adjustable pallet height to solve the technical problems of time-consuming and labor-intensive pallet height adjustment, slow adjustment speed and low efficiency in the prior art.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0005] An electric lifting rack with adjustable pallet height includes a main frame, pallets, a lifting mechanism, and a control mechanism. The pallets are mounted on the main frame via the lifting mechanism, and the control mechanism is communicatively connected to the lifting mechanism.

[0006] The lifting mechanisms are arranged in pairs, symmetrically positioned at the left and right ends of the main frame. Each mechanism includes a through-type stepper motor, a screw, and a vertical guide. The screw is vertically fixed between the front and rear sides of the main frame via a screw retainer. The through-type stepper motor is mounted on the screw and is connected to the screw via a drive mechanism. The through-type stepper motor is provided with a mounting base. The end of the cargo plate is fixed to the through-type stepper motor via the mounting base.

[0007] The vertical guide part includes a guide rod and a guide sleeve. The guide rod is vertically arranged on the main frame and parallel to the screw. The guide sleeve is fitted on the guide rod, and the outer surface of the guide sleeve is fixedly connected to the end of the cargo plate.

[0008] The number of cargo plates is N, where N is an integer greater than 1. The cargo plate located at the bottom of the main frame is the base plate. The base plate is directly fixed to the main frame and is not connected to the lifting mechanism. The number of through stepper motors in the lifting mechanism on one side of the main frame is N-1. The N-1 through stepper motors are respectively fixedly connected to the N-1 cargo plates above the base plate through mounting seats.

[0009] The number of vertical guide parts is two sets, symmetrically arranged between the front and rear columns at both ends of the main frame, and the screw is arranged between the two sets of vertical guide parts.

[0010] The control mechanism includes a stepper motor controller and a remote controller. The stepper motor controller is electrically connected to the through-type stepper motor, and the remote controller is communicatively connected to the stepper motor controller.

[0011] Each of the cargo pallets is equipped with a flashlight at its end. The flashlight is connected in parallel with the corresponding through-type stepper motor of the cargo pallet and is electrically connected to the stepper motor controller.

[0012] The beneficial effects of this utility model are as follows: This utility model provides an electrically adjustable lifting rack with adjustable pallet height. It uses a screw combined with a through-type stepper motor as the lifting mechanism to raise and lower the pallets. A mounting base is installed on the through-type stepper motor to fix the pallets to the mounting base. This greatly simplifies the structure of the lifting mechanism, making it compatible with the main frame of the rack. It also allows for rapid adjustment of the pallets relative to the main frame at any height without unloading goods or disassembling the pallets, making it simple, convenient, fast, and efficient, thereby maximizing the utilization of rack space.

[0013] In addition, this embodiment also provides lifting guidance for the pallet by setting a vertical guide, which can effectively prevent the pallet from tipping over during the lifting process and ensure the stability of the pallet during the lifting process.

[0014] The technical solution provided by this utility model solves a problem that has been difficult to solve in the use of warehouse racks with a simple structure. It has a simple structure, low cost, high efficiency, and good effect, and is suitable for promotion and application in warehouse racks. Attached Figure Description

[0020] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0021] As shown in Figures 1 and 2, this utility model provides an electric lifting rack with an adjustable shelf height 2, which includes a main frame 1, a shelf 2, a lifting mechanism and a control mechanism. The shelf 2 is mounted on the main frame 1 through the lifting mechanism. The control mechanism is communicatively connected to the lifting mechanism. The control mechanism controls the lifting mechanism to move the shelf 2 relative to the main frame 1, thereby adjusting the height of the shelf 2 and improving the utilization rate of the rack space.

[0022] The lifting mechanisms are arranged in pairs, symmetrically positioned at the left and right ends of the main frame 1, to simultaneously lift the left and right sides of the cargo plates 2. Specifically, each mechanism includes a through-type stepper motor 3, a screw 4, and a vertical guide. The screw 4 is vertically fixed between the front and rear sides of the main frame 1 via a screw retainer 41. The through-type stepper motor 3 is mounted on the screw 4 and is connected to it for transmission. In each lifting mechanism, the number of through-type stepper motors 3 corresponds one-to-one with the number of cargo plates 2. A mounting base 5 is fixed to each through-type stepper motor 3, and one end of the cargo plate 2 is fixed to the through-type stepper motor 3 via the mounting base 5.

[0023] This embodiment utilizes a through-type stepper motor 3 in conjunction with a screw 4. This allows the through-type stepper motor 3 to move the corresponding cargo plate 2 up and down while simultaneously keeping the screw 4 stationary. This ensures the fixed position of other inactive through-type stepper motors 3 relative to the screw 4, thereby keeping the corresponding cargo plate 2 stationary during adjustment. This technical solution greatly simplifies the structure of the lifting mechanism and enables the cargo plate 2 to achieve individual, rapid, and convenient height adjustment, making it simple and practical.

[0024] Furthermore, the vertical guide section is used to guide the pallet 2 during the lifting and lowering process driven by the through-type stepper motor 3, preventing the pallet 2 from tilting during the lifting and lowering process. Specifically, the vertical guide section includes a guide rod 6 and a guide sleeve 7. The guide rod 6 is a smooth rod, vertically arranged at the end of the main frame 1 and parallel to the screw 4. The guide sleeve 7 is fitted onto the guide rod 6 and has the freedom to slide relative to the guide rod 6. The outer surface of the guide sleeve 7 is fixedly connected to the end of the pallet 2. In this embodiment, a single set of vertical guide sections includes two guide rods 6 and guide sleeves 7, which are symmetrically arranged at the ends of the left and right sides of the main frame 1, thereby providing guidance to both sides of the pallet 2 simultaneously, so that the pallet 2 remains balanced during the loading and lifting of goods.

[0025] In this embodiment, in order to provide guidance to both the front and rear sides of the cargo plate 2 and to avoid the mounting seat 5 on the through stepper motor 3 being subjected to pressure in the tilt direction, two sets of vertical guide parts are provided in this embodiment. The two sets of vertical guide parts are symmetrically arranged between the front and rear columns 9 at both ends of the main frame 1, and the screw 4 is arranged between the two sets of vertical guide parts.

[0026] As shown in Figure 1, the main frame 1 has N cargo plates 2, where N is an integer greater than 1. In this embodiment, N = 4. The cargo plate 2 located at the bottom of the main frame 1 is the base plate 8, which is directly fixed to the main frame 1 and not connected to the lifting mechanism. The remaining cargo plates 2 are numbered from top to bottom as: cargo plate 2A, cargo plate 2B, and cargo plate 2C. Corresponding to the cargo plates 2, in this embodiment, the lifting mechanism on one side of the main frame 1 has N-1 through-type stepper motors 3, that is, there are N-1 groups of through-type stepper motors 3 in the lifting mechanism. The N-1 through-type stepper motors 3 are fixedly connected to the N-1 cargo plates 2 above the base plate 8 through mounting bases 5. In this embodiment, the main frame 1 has 3 through-type stepper motors 3 on one side, that is, there are 3 groups of through-type stepper motors 3 in the lifting mechanism. Each group of motors is driven synchronously and is numbered from top to bottom as: stepper motor A, stepper motor B, and stepper motor C.

[0027] Furthermore, as shown in Figures 1 and 4, in order to control the operation of the through-type stepper motor 3, the control mechanism in this embodiment includes a stepper motor controller 10 and a remote controller 11. The stepper motor controller 10 is electrically connected to each group of through-type stepper motors 3 to control the synchronous operation of the same group of through-type stepper motors 3. The remote controller 11 is communicatively connected to the stepper motor controller 10 to send control commands to the stepper motor controller 10, such as selecting the stepper motor to be operated or the motor's lifting / lowering. In this embodiment, to facilitate the control of the corresponding pallet 2's lifting / lowering using the remote controller 11, as shown in Figure 3, the remote controller 11 is equipped with four buttons: a motor option 112 button to select the corresponding motor, corresponding motor rise 111 and corresponding motor fall 113 buttons to control the selected motor's rise and fall, and corresponding motor stop 114 button to control the motor's stop operation. Additionally, to facilitate observation of whether the remote controller 11 can send signals normally, an indicator light is also provided in the upper right corner of the remote controller 11. When a button on the remote controller 11 is pressed, the indicator light flashes once.

[0028] Furthermore, to facilitate staff selection of the pallets 2 that need to be raised or lowered, in this embodiment, each pallet 2 is equipped with a flashlight 12 at its end. Each flashlight 12 is electrically connected to the corresponding through-type stepper motor 3 and stepper motor controller 10, specifically in parallel with the corresponding through-type stepper motor 3. To facilitate differentiation and control, the flashlights 12 are numbered according to the pallet 2. In this embodiment, the flashlights 12 are labeled from top to bottom as: Flashlight A, Flashlight B, and Flashlight C. When the through-type stepper motor 3 that needs to be raised or lowered is selected, the branch circuit containing the through-type stepper motor 3 and the flashlight 12 connected in parallel with it is open, and the flashlight 12 on the pallet 2 corresponding to that motor lights up, thus alerting the staff.
