Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a wirelessly controlled telescopic belt conveyor. Background Technology

[0002] Telescopic belt conveyors are commonly used in logistics centers, corporate warehouses, express delivery, airports, and other settings. They can be used in conjunction with other conveying equipment and material sorting systems to automate the inbound and outbound processes of materials or the loading and unloading of vehicles, greatly improving the efficiency of cargo transfer.

[0003] Currently, most telescopic belt conveyors in practical applications use wired control. The front control board installed at the front of the telescopic frame is electrically connected to the control box installed at the rear of the fixed frame via connecting cables for power supply and control signal transmission. The connecting cables are installed inside the fixed and telescopic frames via tank chains. As the service life increases, the connecting cables frequently fail. The cost of the connecting cables themselves is not high, but repairing or replacing the connecting cables requires contacting the manufacturer's maintenance personnel to disassemble the telescopic and fixed frames, which greatly increases labor and time costs and affects and reduces material conveying and sorting efficiency.

[0004] Chinese patent (authorization announcement number CN 207450918 U, authorization announcement date 2018.06.05) discloses a telescopic belt conveyor with an improved tank chain setup. Its technical solution creatively changes the way the tank chain is set up. By changing its running trajectory, only sufficient lateral space is needed, thereby reducing the longitudinal space occupied and making it easier for workers to load and unload goods. However, its technical solution still relies on a cable-connected control method for the tank chain, which cannot overcome the technical problem of high maintenance costs caused by failure of the connecting cable.

[0005] Therefore, how to provide a wirelessly controlled telescopic belt conveyor by improving the wired control method of the front-end control board to a wireless control method, thereby reducing maintenance costs, is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, this utility model proposes a wirelessly controlled telescopic belt conveyor, aiming to solve the technical problem of high maintenance costs due to connection cable failures in the front-end control board of the traditional belt conveyor.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a wirelessly controlled telescopic belt conveyor, comprising:

[0009] A fixed frame and a telescopic frame, wherein the telescopic frame is telescopically mounted on the fixed frame;

[0010] A control component includes an electrical control box, a front-end control board, a rechargeable power supply, a charging cable assembly, and a wireless communication component. The electrical control box is mounted on the fixed frame. The front-end control board and the rechargeable power supply are both mounted on the front of the telescopic frame. The front-end control board is wirelessly connected to the electrical control box via the wireless communication component to send control commands. The rechargeable power supply is electrically connected to the front-end control board to supply power to it. One end of the charging cable assembly is electrically connected to the electrical control box, and the other end is detachably electrically connected to the rechargeable power supply to charge it.

[0011] This utility model of a telescopic belt conveyor eliminates the need for cable connections between the electrical control box and the front-end control board. The front-end control board sends control commands to the electrical control box via a wireless communication component to control the operation of the telescopic belt conveyor. Since the front-end control board and the electrical control box are wirelessly connected, the front-end control board is powered by a rechargeable power supply. This rechargeable power supply can be connected to the electrical control box via a charging cable assembly, using the power supply in the electrical control box to charge it. The other end of the charging cable assembly is detachably connected to the rechargeable power supply. Charging is performed while the telescopic frame is retracted, and the charging cable assembly can be disconnected once fully charged without affecting the telescopic movement of the frame. This utility model improves upon the wired control method of the front-end control board by replacing it with a wireless control method. Disassembling the front-end control board and replacing / maintaining the wireless communication component is much easier than disassembling the fixed or telescopic frame, reducing maintenance costs, increasing maintenance speed, and ensuring that material conveying and sorting operations are not affected.

[0012] As a further improvement to the above technical solution, the front-end control board includes a control button assembly and a lighting lamp installed on the outer wall of the front part of the telescopic frame;

[0014] The rechargeable power supply is electrically connected to the wireless transmitting component to provide power; the control button component is electrically connected to the lighting lamp to control the lighting lamp to turn on and off.

[0015] The beneficial effects of the above technical solution are as follows: the control button assembly can transmit control command signals via a wireless transmitter, and the wireless receiver assembly receives the control command signals and transmits them to the electrical control box for operation control of the telescopic belt conveyor. A rechargeable power supply can power the lighting, ensuring a good working environment for handling personnel. The start / stop control of the lighting is also controlled by the button assembly, facilitating the operation of the lighting by handling personnel located on the front perimeter of the telescopic frame.

[0017] The beneficial effects of the above technical solution are: the electrical control box can control the lifting action of the lifting end of the lifting mechanism, and when the lifting end of the lifting mechanism rises or falls, it can drive the fixed frame to rotate around the hinge axis to adjust the conveying angle.

[0018] As a further improvement to the above technical solution, the control button assembly includes an extension button and a retraction button for controlling the telescopic belt conveyor's telescopic movement, as well as an up button and a down button for adjusting the conveying angle of the telescopic belt conveyor; the extension button, the retraction button, the up button, and the down button are all electrically connected to the wireless transmitting assembly.

[0019] The beneficial effects of the above technical solution are as follows: pressing the extend button transmits an extend command via the wireless transmitter component. After receiving the extend command, the wireless receiver component transmits it to the electrical control box, thereby controlling the extension of the telescopic frame; pressing the retract button transmits a retract command via the wireless transmitter component. After receiving the retract command, the wireless receiver component transmits it to the electrical control box, thereby controlling the retraction of the telescopic frame; pressing the raise button transmits a raise command via the wireless transmitter component. After receiving the raise command, the wireless receiver component transmits it to the electrical control box, which controls the drive end of the lifting mechanism to lift, thereby driving the fixed frame to rotate around the hinge axis, and thus causing the front end of the telescopic frame to rise; pressing the lower button transmits a lower command via the wireless transmitter component. After receiving the lower command, the wireless receiver component transmits it to the electrical control box, which controls the drive end of the lifting mechanism to lower, thereby driving the fixed frame to rotate around the hinge axis, and thus causing the front end of the telescopic frame to lower.

[0020] As a further improvement to the above technical solution, the control button assembly also includes a start button and a stop button for controlling the start and stop of the telescopic belt conveyor, as well as a lighting button for turning the lighting on and off; the start button, the stop button, and the lighting button are all electrically connected to the wireless transmitting assembly.
