Description
Technical Field
[0001] This utility model relates to an environmentally friendly conveying device, and in particular to a multi-purpose environmentally friendly chain bucket unloader. Background Technology
[0002] Currently, ships transporting solid raw materials such as iron ore, sand, coal, and grain are mostly unloaded at the dock by repeatedly grabbing, lifting, and releasing materials using grab cranes. This type of machinery requires actions such as grabbing, lifting, rotating, and releasing the bucket, with most of the time spent on repetitive rotation of the equipment itself, wasting significant energy and time. This results in low efficiency, high mechanical wear and tear, and high unloading costs. Furthermore, the open structure leads to problems such as excessive dust generation, significant cargo damage, and low safety, failing to meet current national environmental protection requirements. Utility Model Content
[0003] The purpose of this utility model is to provide a safe, efficient, energy-saving, multi-purpose, and environmentally friendly bucket unloader to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following first technical solution: a multi-purpose environmentally friendly chain bucket unloader, comprising an unloading section and a loading section, wherein the unloading section comprises an unloading main frame, the unloading main frame being a frame structure, wherein an unloading electric conveyor belt is provided at its bottom, and upper and lower tracks are provided on both sides inside the columns of the unloading main frame.
[0005] The loading section includes an electric trolley, a loading bracket, and a chain bucket mechanism. The electric trolley is equipped with rollers at its bottom that can move between the upper and lower tracks. It contains a trolley drive unit and a hydraulic pump assembly. The trolley drive unit provides power for the electric trolley to move on the upper and lower tracks, and the hydraulic pump assembly provides power for the hydraulic system of the entire equipment.
[0006] The loading support is a frame structure with an electric loading conveyor belt installed at the bottom. The lower end of the conveyor belt's head is hinged to the lower end of the electric trolley's tail. A pulley system is installed at the upper end of the conveyor belt's head, connected by a steel cable to the pulley system at the upper end of the electric trolley's tail, and finally to a winch mounted on the electric trolley. The winch retracts and extends the steel cable to achieve the loading support's rotation and lifting function. Simultaneously, by adjusting the loading support to a horizontal position, the electric trolley can retract the entire loading support into the unloading main frame for easy placement during work stoppages.
[0007] The loading support is also equipped with a chain bucket mechanism at its tail. This mechanism includes a chain bucket support and chain buckets mounted on the support. The chain bucket mechanism is powered by a motor on a chain bucket drive shaft located at the discharge end. The chain bucket drive shaft and bearing housing are hinged to the tail end of the loading support. A pulley system is located at the top of the chain bucket support, connected by a steel wire rope to the pulley system located at the upper tail end of the loading support, and finally connected to a second winch mounted on an electric traveling vehicle. The rotation and swing function of the chain bucket mechanism is achieved by the second winch winding and unwinding the steel wire rope.
[0008] As a further embodiment of this technical solution, the vehicle drive device includes a drive motor, a drive sprocket connected to the output shaft of the drive motor, and a driven sprocket located near the drive sprocket. It also includes a drive chain that wraps around the drive sprocket and driven sprocket in an S-shape, with both ends of the drive chain fixedly connected to the two ends of the unloading main frame. By driving the drive sprocket to rotate in both directions, and through the coordination of the driven sprocket and drive chain, the electric vehicle can move left and right. The driven sprocket serves to tension the drive chain.
[0009] As a further embodiment of this technical solution, another implementation of the vehicle drive device is as follows: it is equipped with a drive motor, a drive gear connected to the output shaft of the drive motor, and a drive rack meshing with and fixedly mounted on the unloading main frame. By driving the drive gear to rotate forward and backward, and cooperating with the drive rack, the electric vehicle can move left and right.
[0010] As a further embodiment of this technical solution, a mobile platform is provided below the unloading section, and outriggers and electric wheels are provided below the mobile platform. The electric wheels are mounted on two parallel steel rails. The steel rails can be installed on the dock or on the ship hull according to the actual needs of the site.
[0011] As a further embodiment of this technical solution, the top of the mobile platform is provided with a rotating platform that can rotate 360 degrees horizontally. A rectangular bracket is fixed on the rotating platform, and the unloading main frame is installed on the bracket.
[0012] The combination of the lateral movement of the mobile platform, the rotational movement of the rotary table, and the actions of the No. 1 and No. 2 winches in raising and lowering the wire ropes enables the entire machine to completely unload cargo from every corner of the target ship's hold without any blind spots.
[0013] As a further embodiment of this technical solution, the unloading section also includes a counterweight frame. The inner side of the counterweight frame is hinged to the two outer sides of the top of the main unloading frame. The upper end of the counterweight frame is hinged to the top of the electric trolley via a traction linkage. A counterweight bag is fixedly installed at the lower end of the counterweight frame. While the electric trolley is moving back and forth, the counterweight bag provides a gravitational balance.
