Description

Technical Field

[0001] This utility model relates to the field of kiln car unloading, and in particular to a mobile unloading device for multi-layer kiln cars. Background Technology

[0002] Kiln cars are key equipment in tunnel kilns or shuttle kilns used to carry products (such as brick blanks, ceramics, etc.) for firing and transportation. They are characterized by high temperature resistance, structural stability and reusability. Through multi-layer structural design (such as three or more horizontally arranged kiln frames), the product loading capacity of a single kiln car can be greatly increased, thereby significantly improving the kiln's output per unit time. At the same time, it can save more than 50% of fuel and reduce the fuel consumption per unit product. In existing multi-layer kiln cars, unloading is often done manually. Therefore, unloading can only be carried out when the kiln car leaves the kiln. Due to its large load capacity, a single unloading point cannot meet the space requirements for unloading materials, and the unloading point needs to be changed frequently. In addition, during the unloading process, the materials need to be removed from different layers and then smoothly conveyed to the unloading point by the unloading device. Reliable steering and lifting functions are required. Therefore, we propose a mobile unloading device for multi-layer kiln cars. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a mobile unloading device for multi-layer kiln cars. This device features a reliable material handling unit that can effectively remove material from each layer of the kiln car. Hydraulic cylinder two pushes the lifting rod outwards. After the lifting rod extends into the lifting rod slot, hydraulic cylinder one pushes the telescopic rod upwards, thereby lifting the material off the surface of the unloading plate. Subsequently, hydraulic cylinder one drives the material to rise and fall, while the motor drives the mounting frame and lifting rod to adjust their direction, thus transferring the removed material to the unloading station. Wheels allow the entire device to move. Combined with the automated material handling mechanism, the device can achieve mobile unloading between multiple unloading points. Hydraulic cylinder three controls the movable bracket and belt conveyor to push outwards. The removed material is first placed on the horizontal end of the belt conveyor and then transported downwards by the belt conveyor, thus completing the unloading operation. This effectively solves the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mobile unloading device for a multi-layer kiln car, comprising a car frame body, a material handling unit, and an unloading unit, characterized in that: The frame body has a wheel installed at each of the four corners at the bottom. Material handling unit: includes hydraulic cylinder one, connecting block, chuck, mounting frame, motor, hydraulic cylinder two, and lifting rod. A vertical hydraulic cylinder one is installed at the lower position on both sides of the main body of the frame. The telescopic end of hydraulic cylinder one faces upward and a circular connecting block is fixedly connected to its upper end. The chuck is set above the connecting block and a motor is embedded in its internal center. The motor housing is fixedly connected to the chuck, and the output shaft of the motor faces downward and is fixedly connected to the center position inside the connecting block.

A lifting rod is fixedly connected to the telescopic end of each hydraulic cylinder two and is slidably connected to the mounting frame. Unloading unit: Installed on the upper and rear sides of the main frame.

[0005] Hydraulic cylinder two is used to push the lifting rod outward.

Hydraulic cylinder one is used to drive the mounting frame to lift and lower. The connecting block is used for the fixed connection between the motor output shaft and the telescopic end of hydraulic cylinder one. When the motor is powered on, it can drive the chuck to rotate, thereby driving the mounting frame and the lifting rod to adjust their direction, and then transferring the removed material to the unloading station.

The drive motor of the ball screw is installed inside the front end of the main frame body. The mounting platform is used for mounting the hydraulic cylinder, and the bracket supports the lower end of the bracket. When the ball screw is running, it can drive the mounting platform to move horizontally, thereby enabling the lifting rod to reach the position of the corresponding goods during material handling and allowing the lifting device to carry the goods to the belt conveyor after material removal.

[0007] Furthermore, the unloading unit includes vertical supports, support blocks, and a discharge plate. A vertical support is fixedly connected to each of the four corners of the upper part of the vehicle frame. The vertical support has an L-shaped cross-section.

The support blocks support the discharge plate, which is used to hold the material transported by the kiln car.

[0008] Furthermore, the unloading unit also includes a central baffle, lifting rod slots, and an industrial camera. A central baffle is fixedly connected to the middle side of each unloading plate. Three sets of lifting rod slots are respectively opened on the left and right sides of the central baffle. Each set of lifting rod slots includes two parallel grooves, and the width between the two grooves is equal to the distance between two adjacent lifting rods. An industrial camera is embedded in the section of the mounting bracket facing the center of the device. The upper two unloading plates, together with the upper end of the frame body, provide three layers of material placement areas. The central baffle divides each unloading area into left and right sections, thus providing sufficient material placement space. The lifting rod slots allow lifting rods to be inserted, enabling them to support the bottom of the material for easy lifting and moving. The industrial camera can capture images during the lifting process, allowing the computer to determine whether the material has been lifted off the unloading plate.

A belt conveyor is installed on the upper side of each movable bracket, and the belt conveyor, like the movable bracket, has a folded structure. The hydraulic cylinder three controls the movable bracket to extend outwards. The movable bracket is used for mounting the belt conveyor. The unloaded material is first placed on the horizontal end of the belt conveyor and then conveyed downwards by the belt conveyor, thus completing the unloading operation.

[0010] Furthermore, it also includes a computer unit and a wireless signal transmitter. The computer unit is embedded in the middle of the rear of the main frame, and the wireless signal transmitter is installed at the upper diagonal corner of the computer unit. The input terminals of hydraulic cylinder one, hydraulic cylinder two, hydraulic cylinder three, belt conveyor, electric motor, and ball screw auxiliary drive motor are all bidirectionally electrically connected to the control terminal of the computer unit.
