Description

TECHNICAL FIELD

[0001] The utility model relates to material bearing trolley technical field, concretely for a kind of automatic lifting maintenance mechanism for aerial conveying type material bearing trolley. BACKGROUND

[0002] With the rapid development of industrial technology, the demand for material conveying is increasing, and the traditional ground transportation method cannot meet the efficient and flexible operation demand. The ground conveying system generally adopts equipment flat layout method, that is, all equipment is placed in sequence in ground space. To further improve transportation efficiency and expand space utilization, enterprises begin to transfer the direction of material conveying to the air space. The aerial track ring shuttle trolley (referred to as aerial trolley) is a kind of suspended monorail shuttle system, which is gradually valued as a new type of transport tool due to its small space occupation and fast moving speed.

[0003] The aerial trolley realizes three-dimensional transportation through suspended track and ground-air interface conveying. Through the layout of aerial conveying line layout, the problem of insufficient ground space is effectively solved, and the flexibility and efficiency of material conveying are improved.

[0004] It realizes material conveying by fixing the track in the air and using the equipment suspended under the track to drive along the track, so as to avoid occupying ground space and realize material conveying in the air.

[0005] Since the aerial trolley conveying system is distributed in the air, the point inspection and maintenance work of the aerial trolley equipment becomes a place that needs to be considered. Generally, if the aerial conveying line layout is not high, the point inspection and maintenance personnel can directly maintain the aerial trolley equipment on the track through the way of scaffold or ladder.

[0006] Generally, the direct maintenance method is undoubtedly the most convenient and efficient way for the whole system design. Under this scheme, the maintenance worker can directly inspect and maintain the in-place aerial trolley, and quickly locate the problem.

[0007] However, since the aerial trolley line is generally laid in the air, direct maintenance on the track needs to climb to carry out point inspection and maintenance work, which has certain degree of safety hazard and low efficiency. High-altitude operation has high risk, and safety protection measures need to be equipped, which increases the cost. At the same time, frequent climbing of ladder is time-consuming and laborious, which affects the overall operation efficiency. Moreover, the traditional maintenance method is difficult to deal with complex faults, and professional technical personnel are needed to support, which further increases the maintenance difficulty and cost.

[0008] Furthermore, since on-rail maintenance must be performed under conditions of complete line shutdown, the aforementioned maintenance method using elevated equipment for on-rail inspection is more suitable for production tasks involving a single car and a single rail. When there are multiple cars transporting goods on the same rail, on-rail maintenance will cause the entire conveyor line to suspend its transport operations. If any car requires maintenance, the entire line will stop, causing a chain reaction and delaying production progress. This greatly affects the overall transport operations and severely impacts production efficiency.

[0009] Therefore, there is an urgent need for an automatic lifting and maintenance mechanism for aerial material transport trolleys to solve the above-mentioned technical problems. Utility Model Content

[0010] The purpose of this invention is to provide an automatic lifting and maintenance mechanism for an aerial material transport trolley, so as to solve the technical problems mentioned in the background art.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

The first spacer separates the take-up and release pulleys. The driven shaft guide assembly consists of a driven shaft, guide pulleys, a second bearing seat, and a second spacer. The second bearing seat fixes the driven shaft to the main frame, and the second spacer positions and fixes the guide pulleys. The lifting rail is an independent rail assembly for supporting and mounting the aerial trolley. The lifting rail is fixed to the end of a webbing using a webbing clamp and is raised and lowered by the take-up and release of the webbing. The lifting rail consists of a webbing clamp, a rail, a sliding contact line, and a positioning and guiding assembly.

[0013] Preferably, various perforated sheet metal structures of different sizes are welded onto the main frame to facilitate the assembly and connection of various components and the overall installation and fixation of the mechanism.

[0014] Preferably, a flat plate with mounting holes is welded to the upper end face of the main frame for mounting and positioning the overall mechanism.

[0015] Preferably, the drive lifting shaft assembly consists of a drive shaft fixed to the main frame via a first bearing seat and connected to a geared motor via a coupling.

[0016] Preferably, the webbing clamp is used to suspend and fix the bracket of the trolley carrying track structure. It is formed by sheet metal welding and bolted together. One end is fixed in the groove on the upper surface of the track profile, and the other end is clamped and fixed by bolts to the sheet metal.

[0017] Preferably, the sliding contact line provides driving power for the trolley when it enters the lifting area. Power supply through the sliding contact line ensures stable power when the trolley enters and exits the lifting area.

[0018] Preferably, the positioning guide assembly is divided into two parts: a vertical lifting guide and a side docking guide. The vertical lifting guide is a rod-shaped structure that is directly fixed to the upper end face of the track profile by bolts. The side docking guide is a plate-shaped structure that cooperates with the docking structures at each docking position.

[0019] Preferably, the adjusting rod is composed of a rod fixing seat, a double-ended stud, a rail fixing seat, and fixing bolts. The adjusting rod is installed on the main frame, and the rail fixing seat is connected to the upper end face of the lifting rail. The two are adjusted and connected by a double-ended stud and a nut.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention incorporates a modular design into the system circuit design of the aerial trolley, enabling rapid inspection and maintenance of the aerial trolley. This mechanism significantly improves the maintenance efficiency of the aerial trolley, reduces downtime, and lowers maintenance costs. Its high-precision guiding system ensures operational stability and extends equipment lifespan. The modular design facilitates installation and replacement, adapts to various working environments, and effectively enhances the overall system's reliability and flexibility. Designing the aerial trolley system circuit using this scheme greatly reduces the difficulty of aerial trolley inspection and maintenance, simplifies the operation process, and reduces labor intensity. Simultaneously, this scheme avoids the safety risks associated with working at heights, reducing potential risks in inspection and maintenance. Furthermore, this scheme ensures the non-interference operation of multiple aerial trolleys on the same track; that is, the trolley requiring inspection can be placed separately in a specific maintenance area without affecting the normal transport operations of other trolleys, ensuring the continuity and efficiency of the overall production line.
