Description
Technical Field
[0001] The utility model belongs to the technical field of suspension vehicle maintenance, and in particular relates to a driving wheel guide device for a suspension vehicle. Background Art
[0002] Currently, the suspension vehicles are the vital arteries of vertical warehouse operations, operating at a normal speed of 90 m / min and capable of carrying over 40 kilometers of cargo non-stop throughout the day. The vehicles lack a power supply; instead, power and signals are transmitted through carbon brushes and overhead rail sliding wires to control the suspension vehicles' various tasks. One set of driving wheels and two sets of driven wheels are mounted on the roof of the vehicle body. The main reducer and the driving wheels are connected via expansion sleeves, driving the vehicles on a 4.5-meter-high overhead rail. The suspension vehicles automatically and efficiently operate in a single-direction tandem. If any vehicle malfunctions and stops, all 43 vehicles will be forced into a long queue within 10 minutes, blocking their operations and paralyzing the entire vertical warehouse system. The driving and driven wheels of the suspension vehicles are constructed of a steel core with an outer layer of a specialized polyurethane polymer. Both the driving and driven wheels are fixed to the vehicle body seat. When the suspension vehicle body fails to operate, gravity hangs on the overhead rail, and the driving wheel drive is controlled by the reducer. If the driving wheel brakes are not applied, manual propulsion becomes nearly impossible. Faults that can cause the driving wheels to become inoperable include:
[0003] (1) The driving and driven wheels of the suspension vehicle have been running at high speed for a long time and have reached the end of their life cycle (20 months). During the operation, the polyurethane suddenly burst and fell off, causing the suspension vehicle to get stuck on the overhead rail and unable to run, resulting in a major production accident.
[0004] (2) The speed reducer and manual brake components of the suspension vehicle are exposed to high temperatures for a long time, which can easily cause gear wear, internal jamming, and inability to transmit power, making it impossible to drive the driving wheel.
[0005] Since the trolley system has two maintenance areas on both sides of the trolley channel, when the above-mentioned driving wheel stuck fault occurs, maintenance personnel can only operate at high altitude on site. They need to use tools to lift the car body and let the driving wheel leave the overhead rail before pushing the car into the maintenance area. The assistance of multiple groups of people is needed to push the car forward. When pushing, it is also necessary to pay attention to the unevenness of the driving wheel after the burst to prevent scratching the overhead rail. The uneven overhead rail can easily damage the transmission wheels and conductive carbon brushes of other cars, causing secondary damage. Most of the outer ring of the driving wheel has fallen off, and the driving wheel will not be able to run along the overhead rail, making it impossible to push the suspension car. The entire set of reducers can only be replaced on site. The time to handle the fault will exceed 60 minutes, seriously affecting production.
[0006] Therefore, a new technology is needed to solve the problem in the prior art that the suspension vehicle cannot move due to a failure of the driving wheel. Utility Model Content

[0034] Reference Figures 1 to 5 A driving wheel guide device for a suspension vehicle comprises a connecting seat 1, a wheel frame 2 and a guide wheel group 3. The connecting seat 1 is located above the suspension vehicle and is detachably fixedly connected to the front end of the suspension vehicle. The wheel frame 2 is used to install the guide wheel group 3 and is connected to the connecting seat 1. The guide wheel group 3 is located at the front end of the suspension vehicle and is rollingly connected to the upper surface of the ceiling rail. When the guide wheel group 3 contacts the surface of the ceiling rail, there is a gap between the driving wheel of the suspension vehicle and the surface of the ceiling rail. When the suspension vehicle is pushed hard, the guide wheel group 3 can roll along the upper surface of the ceiling rail as the running guide wheel of the suspension vehicle, and can replace the original driving wheel to guide the operation of the ceiling rail, so that the suspension vehicle can move along the ceiling rail. Connecting plates 13 are protruding from both sides of the connecting seat 1. The two ends of the wheel frame 2 are respectively connected to one of the connecting plates 13. The ends of the two connecting plates 13 away from the wheel frame 2 are both detachably fixedly connected to the front end of the suspension vehicle. The guide wheel assembly 3 can be composed of three side wheels from an old suspension vehicle, arranged in parallel. Each side wheel inner ring is equipped with a 6205 bearing, and each side wheel outer ring is made of polymer material. They are rotatably mounted on the central shaft 23, which can reduce production costs. The diameter of the central shaft 23 can be 20 mm, and shaft retaining rings are installed at both ends of the central shaft 23 to prevent the guide wheel assembly 3 from moving along the central shaft 23 when under pressure.
[0035] Specifically, the connecting seat 1 includes a first fixing plate 11 and a second fixing plate 12 connected to each other in an L-shape. The first fixing plate 11 is vertically arranged and detachably fixed to the suspension vehicle. One end of the two connecting plates 13 is fixedly connected to the first fixing plate 11, and the other end is connected to the wheel frame 2; the second fixing plate 12 is horizontally arranged and is located on the upper surface of the suspension vehicle body. The first fixing plate 11 is fixedly mounted on the front end of the driving wheel support frame by bolts. The first fixing plate 11 is provided with at least two mounting holes 111, each mounting hole 111 corresponding to the screw hole position of the front end of the driving wheel support frame. Two mounting holes 111 can be opened on the first fixing plate 11 as corresponding M10 screw hole positions, and directly fixed to the original screw hole position of the front end of the driving wheel by bolts. The middle part of the second fixing plate 12 is bolted to the upper end face of the suspension vehicle by a positioning bolt, and the height can be adjusted at the same time. A positioning hole 121 is provided in the middle of the second fixing plate 12, serving as an M12 screw hole. Bolts are used to secure the second fixing plate 12 to the original driving wheel seat. The spacing between the second fixing plate 12 and the ceiling rail can be adjusted, as can the height of the connecting seat 1 and roller 31 relative to the ceiling rail, ensuring contact between the roller 31 and the ceiling rail while maintaining a gap between the original driving wheel and the ceiling rail. The spacing between the second fixing plate 12 and the upper end surface of the suspension vehicle can be adjusted by inserting a gasket between the second fixing plate 12 and the upper end surface of the suspension vehicle.
[0036] Specifically, the two connecting plates 13 are both located above the second fixing plate 12 , and the two connecting plates 13 and the second fixing plate 12 are both located on the same side of the first fixing plate 11 .
[0037] Specifically, the guide wheel assembly 3 includes a plurality of coaxially arranged rollers 31. The wheel frame 2 includes a first side plate 21, a second side plate 22, and a central shaft 23. The central shaft 23 sequentially passes through the center holes of each roller 31 and is connected at both ends to the first side plate 21 and the second side plate 22, respectively. The first side plate 21 is connected to the first fixed plate 11, and the second side plate 22 is connected to the first fixed plate 11. The first side plate 21 and the second side plate 22 are parallel to each other, and their lower portions are close to or in contact with the end surface of the suspension vehicle. The ends of the central shaft 23 are rotatably mounted on the first side plate 21 and the second side plate 22, respectively. The first side plate 21 and the second side plate 22 are each provided with a through hole 211 for inserting the end of the central shaft 23.
[0038] Specifically, the connecting plates 13 are in the shape of a right triangle, one right-angled side of each connecting plate 13 is connected to the first fixing plate 11 , and the other right-angled side is located at the lowermost end.
[0039] Specifically, there is a distance between the lower end of each connecting plate 13 and the second fixing plate 12 .
[0040] Specifically, the upper portion of the first side plate 21 is fixedly connected to the connecting plate 13 and the second fixing plate 12 in sequence from top to bottom, and the upper portion of the second side plate 22 is fixedly connected to the connecting plate 13 and the second fixing plate 12 in sequence from top to bottom.
[0041] Specifically, elastic washers 4 are provided between the guide wheel assembly 3 and the first side plate 21 and the second side plate 22 .
[0042] Specifically, both ends of the central shaft 23 are fitted with elastic retaining rings 5, and the first side plate 21 and the second side plate 22 are both located between the two elastic retaining rings 5. The setting of the two elastic retaining rings 5 can prevent the central shaft 23 from escaping from the through hole 211 on the first side plate 21 or the second side plate 22.
[0043] A method for using a driving wheel guide device for a suspension vehicle, using the driving wheel guide device for a suspension vehicle as described above, comprises the following steps:
[0044] S1. If the driving wheel fails and the vehicle cannot be driven, immediately use a jack to raise the vehicle body on site so that the original driving wheel is 1-2mm away from the overhead track.
[0045] S2. Fix the driving wheel guide device of the suspension vehicle to the two screw holes at the front end of the suspension vehicle. That is, connect the first fixing plate 11 to the suspension vehicle through the two screw holes at the front end of the suspension vehicle and the two mounting holes 111 on the first fixing plate 11.
[0046] S3. By adjusting the bottom bolts, the guide wheel assembly 3 is brought into contact with the overhead rail, creating a gap between the original driving wheel and the overhead rail, allowing them to separate. Specifically, the roller 31 is brought into contact with the overhead rail and can roll along the surface of the overhead rail when the suspension vehicle is pushed. The gap between the original driving wheel and the overhead rail shields the original driving wheel from being stuck. Bearings are provided between the guide wheel assembly 3 and the central shaft 23, and transmission is achieved through the bearings. This allows the suspension vehicle to be easily and quickly pushed to the maintenance area, allowing other vehicles to resume operation quickly. If the suspension vehicle's driving wheel wears out or the reducer becomes stuck, preventing manual acceleration, maintenance personnel can quickly install the suspension vehicle's driving wheel guide device on the suspension vehicle. They simply tighten the two bolts securing the first fixing plate 11 to the front end of the original driving wheel support frame, adjust the bottom bolts so that the original driving wheel is 1-2 mm clear of the overhead rail, and immediately push the suspension vehicle back to the nearest maintenance area. This is quick and convenient, allowing other vehicles to resume operation and effectively restoring the vertical warehouse within 20 minutes. The active wheel guide device of the suspension vehicle in this solution only requires two or three people to work together to push the suspension vehicle to complete the movement during the night shift. The process can be completed safely and quickly within 20 minutes, saving manpower, reducing the time for troubleshooting, and maintaining the efficient operation of the vertical warehouse at all times.
[0047] For other contents of the driving wheel guide device of a suspension vehicle described in the present invention, please refer to the prior art and will not be described in detail here.
[0048] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
