Description
Technical Field
[0001] This application relates to the technical field of maintenance racks, and in particular to a maintenance rack for a mixer discharge hopper. Background Technology
[0002] In highly automated concrete production processes, mixers are typically fixed inside mixing towers and installed several stories high. The discharge hopper is the last component for discharging the mixed concrete. To allow the concrete to directly enter the mixer truck, the discharge hopper is usually positioned at a high location to match the height of the mixer truck. Therefore, when inspecting and maintaining the discharge hopper, maintenance personnel need to work at a height, typically using an adjustable-height maintenance frame.
[0003] In related technologies, there are two types of maintenance frames: fixed and mobile. To facilitate periodic maintenance of the discharge hopper and prevent interference between the maintenance frame, the discharge hopper, and the transport vehicle that may affect production, a mobile maintenance frame is generally selected. When performing maintenance, the staff must first climb onto the working platform of the maintenance frame and then raise the working platform so that its height is close to that of the discharge hopper, so that the staff can perform maintenance on the discharge hopper.
[0004] Regarding the aforementioned technologies, mixers are often large mixers with correspondingly large discharge hoppers, while the area of the maintenance frame's working platform is small. This makes it impossible to fully inspect the discharge hopper at once, requiring the maintenance frame to be moved. For the safety of maintenance personnel, personnel must first descend from the maintenance frame before it can be moved, making the maintenance process cumbersome and inefficient. Therefore, this application proposes a maintenance frame for a mixer discharge hopper. Utility Model Content

[0028] Example 1 refer to Figure 1A maintenance frame for a mixer discharge hopper includes a working platform 1, a mounting column 2 that suspends and fixes the working platform 1 to the ceiling, a connecting channel 3 that connects a corridor on one side of the wall to the working platform 1, a gate 4 that adjusts the discharge flow rate of the discharge hopper 10, and a drive component 5 that drives the gate 4 to move.
[0029] refer to Figure 2 In this embodiment, the working platform 1 is located below the discharge hopper 10, with the discharge port of the discharge hopper 10 projected onto the center of the working platform 1. The working platform 1 is parallel to the ceiling and is fixed to the ceiling by mounting columns 2. In this embodiment, the working platform 1 is rectangular, with one side of the working platform 1 against a wall. The connecting channel 3 connects the corridor on the other side of the wall to the working platform 1. The gate 4 is located on the side of the discharge hopper 10 near the working platform 1 and is set close to the discharge port of the discharge hopper 10. The drive unit 5 is installed on the working platform 1 and connected to the gate 4. This arrangement provides maintenance personnel with a large standing area, allowing for comprehensive maintenance and repair of the equipment without moving the maintenance frame. It also allows for adjustment of the discharge flow rate, improving maintenance efficiency and production flexibility. The connecting channel 3 facilitates personnel access to and from the working platform 1. The drive unit 5 controls the movement of the gate 4, thereby precisely controlling the discharge flow rate. In this embodiment, the drive unit 5 is a cylinder.
[0030] Specifically, the work platform 1 is provided with a clearance hole 6 to prevent the work platform 1 from blocking the material output. The clearance hole 6 is located at the center of the work platform 1. The shape of the clearance hole 6 corresponds to the shape of the discharge port of the discharge hopper 10. The edge of the work platform 1 is welded and fixed with a guardrail 7 to prevent maintenance personnel from falling. The work platform 1 is also provided with an air source for supplying gas to the cylinder. In this embodiment, the air source is an air compressor.
[0031] The drive unit 5 is fixed to the working platform 1 by bolts, and the output shaft of the drive unit 5 is fixed to one side of the gate 4 by bolts. The working platform 1 is also bolted with a slide rail 8. One end of the slide rail 8 is welded to the discharge hopper 10 and located at the discharge port of the discharge hopper 10.
