Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of warehouse equipment, and particularly relates to a four-way shuttle automatic stereoscopic warehouse maintenance vehicle. BACKGROUND

[0002] The four-way shuttle automatic stereoscopic warehouse refers to a dense warehouse, which comprises multiple warehouse layers with different vertical heights, and the most basic structure of a single warehouse layer comprises front and rear main tracks, left and right branch tracks, and a goods support frame arranged on the branch track.

[0003] The four-way shuttle automatic stereoscopic warehouse, whose name comprises the words of four-way shuttle and automatic, refers to a shuttle vehicle, which can move in four directions, i.e., front and back and left and right, and is equipped with two sets of bidirectional rotating roller systems. The basic operation method of the shuttle vehicle is as follows: first, the goods with a chassis are stably placed on the shuttle vehicle, and the shuttle vehicle is moved to the corresponding goods shelf position on the main track; second, the shuttle vehicle lifts the goods chassis to be higher than the goods support frame; third, the shuttle vehicle changes the moving direction and enters the corresponding branch track; fourth, the shuttle vehicle lowers the goods chassis and stably places the goods on the goods support frame; and finally, the shuttle vehicle exits the branch track, returns to the main track, and completes the complete goods transportation operation.

[0004] However, in the daily operation process, one of the shortcomings of the dense warehouse is that when the shuttle vehicle fails and stops, it is difficult for the staff to climb into the warehouse to repair or remove the faulty shuttle vehicle.

[0005] Now, a relatively common and simple method is that the staff rides another shuttle vehicle into the track system to perform necessary maintenance operations, but this method also has many problems and shortcomings, for example:

[0006] 1. The upper surface of the shuttle vehicle is flat and has no structure that can be held or leaned against, so it is very dangerous for the staff to ride on it and easy to fall off;

[0007] 2. The staff occupies a perfect shuttle vehicle during maintenance, which reduces the work efficiency of the entire warehouse.

[0008] Therefore, further, there is an urgent need for a maintenance device that allows the staff to ride stably and can be transported to the shuttle vehicle that needs to be repaired by a perfect shuttle vehicle. Finally, the perfect shuttle vehicle can be freed up for normal transportation operations during maintenance.

[0009] The utility model discloses a kind of wheeled three-dimensional warehouse maintenance and repair vehicle structures, including a maintenance and repair vehicle main body, maintenance and repair vehicle main body is equipped with maintenance and repair work platform, maintenance and repair work platform is equipped with one level telescopic support device in left and right sides, the output end of level telescopic support device is equipped with elastic support plate, maintenance and repair work platform is equipped with safety fence around, maintenance and repair work platform is equipped with integrated tool box that can place electrician tool and pneumatic tool, maintenance and repair vehicle main body is arranged on a free walking aerial lift truck, maintenance and repair vehicle main body is equipped with control device that can operate the aerial lift truck, aerial lift truck is equipped with electric lifting drive mechanism connected with the control device.

[0010] But the maintenance and repair vehicle structure in the utility model patent, when being transported by shuttle vehicle, there is the risk of insufficient height of the roller structure, easy to be bottomed, knocking shuttle vehicle itself and track structure.

[0011] So, as described above, there is an urgent need for a maintenance vehicle that can be stably transported by a shuttle vehicle and still has a certain moving function for the accident shuttle vehicle maintenance operation of the four-way shuttle automatic three-dimensional warehouse. SUMMARY

DETAILED DESCRIPTION

[0039] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0040] As attached Figures 1-9 As shown, a four-way shuttle automatic stereoscopic warehouse maintenance vehicle includes a vehicle body frame unit 1 which is successively mounted on a rescue shuttle vehicle a and a cargo support frame b, a lifting and manning plate unit 2 arranged on the vehicle body frame unit 1, and a roller unit 3 which is arranged on the lower surface of the lifting and manning plate unit 2 and is used for rolling on a branch track d.

[0041] In this embodiment, the general usage and advantages of the maintenance vehicle are as follows.

[0042] First, when the maintenance vehicle is in an idle state, the lifting platform unit 2 together with the roller unit 3 is in a relatively high position, that is, the lower bottom surface of the entire maintenance vehicle is the lower bottom surface of the vehicle body chassis unit 1.

[0043] Second, there may be a faulty shuttle a on the main track c or the branch track d. Then the maintenance car is placed on the rescue shuttle, that is, another shuttle a. Then people squat on the lifting manned plate unit 2, start the rescue shuttle, and move towards the faulty shuttle.

[0044] Third, select a branch track d that is closest to the faulty shuttle, place the maintenance vehicle and staff on the cargo support rack b in the same way as loading cargo onto a shelf, and then the rescue shuttle can leave.

[0045] Fourth, the lifting platform unit 2 is lowered together with the roller unit 3 and the staff until the roller unit 3 is pressed on the branch track d. At this time, the vehicle body frame unit 1 can also be actively lifted up a little compared to the lifting platform unit 2 to avoid the vehicle body frame unit 1 rubbing against the cargo support frame b when the maintenance vehicle moves.

[0046] Fifth, the roller unit 3 is manually driven but cannot rotate, so the maintenance vehicle can only roll on the branch track d, or at most move until it hits the main track c, and cannot move along the main track c. At this time, the staff needs to stretch their bodies appropriately to complete the maintenance operation.

[0047] Finally, after the faulty shuttle is repaired, the maintenance vehicle returns to the cargo support frame b, and then retracts the roller unit 3 upwards, and the shuttle takes it away, completing the entire rescue and maintenance operation.

[0048] It should be noted that in the last step, if the staff is still squatting on the lifting board unit 2 when the roller unit 3 is retracted upward, the load of the upward retraction action is large and very laborious, so the better way is that the staff temporarily steps on the vehicle body frame unit 1, that is, indirectly steps on the goods support frame b, so that the lifting board unit 2 and the roller unit 3 are retracted upward very easily.

[0049] Of course, the shuttle vehicle has a lifting board structure, which can take and place the entire maintenance vehicle.

[0050] The vehicle body frame unit 1 includes a rectangular frame body 101, an inner side plate 102 arranged on the rectangular frame body 101, an inner center plate 103 arranged on the inner side plate 102, vertical studs 104 arranged on the inner center plate 103 and used for sleeved mounting the lifting board unit 2, and a lower waiting nut 105 arranged on the vertical stud 104 and used for supporting the lifting board unit 2, and an upper working nut 106 used for blocking the lifting board unit 2.

[0051] In this embodiment, the width of the shuttle vehicle is definitely less than the width of the goods support frame b, so there is a relatively inner shuttle vehicle lifting point on the lower surface of the rectangular frame body 101, and a relatively outer support frame lifting point.

[0052] In addition, the upper surface of the lower waiting nut 105 is provided with a ball to avoid excessive friction between it and the lower surface of the lifting board unit 2, otherwise the lower waiting nut 105 cannot rotate.

[0053] The lifting board unit 2 includes a rectangular plate body 201 arranged between the lower waiting nut 105 and the upper working nut 106, mounting holes 202 arranged on the rectangular plate body 201 and used for inserting the vertical studs 104, and guardrails 203 arranged on the upper surface of the rectangular plate body 201.

[0054] In this embodiment, the area of the rectangular plate body 201 is less than the area of the rectangular frame body 101, and the frame of the rectangular frame body 101 can be temporarily stepped on by the staff to retract the lifting board unit 2 upward.

[0055] The roller unit 3 includes four roller plates 301 respectively arranged at the four end corners of the lower surface of the rectangular plate body 201, a roller body 302 arranged on the side of the roller plate 301 and extending downward relative to the outside of the two inner side plates 102, a limiting hole plate 303 arranged on the lower surface of the rectangular plate body 201, a driving shaft 304 inserted into the limiting hole plate 303, and a driving chain 305 arranged on the driving shaft 304 and the roller body 302.

[0056] In this embodiment, the roller body 302 is inserted into the roller plate 301 and can rotate freely. In addition, a gear is provided on the roller body 302 for engaging with the driving chain 305 to ensure an effective chain transmission effect.

[0057] In addition, the driving shaft 304 may also protrude from the side of the rectangular plate 201 to facilitate its rotation after gripping to drive the entire maintenance vehicle.

[0058] The passenger lifting platform unit 2 further includes a central rectangular hole 204 provided on the rectangular plate body 201 ; the roller unit 3 further includes a driving wheel 306 provided on the driving shaft 304 and located in the central rectangular hole 204 .

[0059] In this embodiment, the driving wheel 306 is made of high-strength rubber and can be rotated by being held by hand, thereby driving the roller body 302 .

[0060] The passenger lifting plate unit 2 further includes two through holes 205 respectively provided at both ends of the central rectangular hole 204 and used for rotating and adjusting the lower waiting nut 105 .

[0061] In this embodiment, the word "through" of the through hole 205 means that it is connected with the middle rectangular hole 204 to form an "I-shaped" structure. If there is no through hole 205, the rotation adjustment action of the lower waiting nut 105 must be performed by reaching down from the side of the rectangular plate 201 to rotate it, which is very troublesome.

[0062] The roller unit 3 further includes a thread groove 307 provided on the annular surface of the driving wheel 306 , and a radial driving column 308 provided on the thread groove 307 and used for performing a limiting and fixing operation between the lower waiting nut 105 and the upper working nut 106 .

[0063] In this embodiment, when the maintenance vehicle comes to the most suitable maintenance position, we need it to stop moving, at this time we can rotate the relatively retracted radial drive column 308 a little bit, and clamp it between the lower standby nut 105 and the upper working nut 106, so that the maintenance vehicle has the function of brake and anti-movement, which is very ingenious and safe.

[0064] Of course, it should be noted that: 1. When the radial drive column 308 is relatively retracted, it is the gripping part of the drive wheel 306 rotation drive, which ensures that the driving operation is more labor-saving; 2. The number of radial drive columns 308 is limited, so the selection of the above brake position is not stepless, and the maintenance vehicle may need to be appropriately backed up to clamp one of the radial drive columns 308 between the lower standby nut 105 and the upper working nut 106.

[0065] The vehicle body chassis unit 1 also includes a U-shaped fixed plate 107 arranged on the opposite outer side of the inner side plate 102 and used for limiting and clamping the roller plate 301, and a vertical limiting groove 108 arranged on the inner side of the U-shaped fixed plate 107.

[0066] In this embodiment, when the rectangular plate body 201 moves up and down, it cannot be greatly skewed, so first the worker needs to stand steady, with his two feet left and right on both sides of the middle rectangular hole 204, and secondly the roller plate 301 is always clamped in the vertical limiting groove 108, which can also greatly reduce the probability of skewing accident.

[0067] The vehicle body chassis unit 1 also includes a lower surface slot 109 arranged on the U-shaped fixed plate 107 and used for extending the lower surface of the roller body 302 outward, and a vertical rectangular hole 110 arranged on the U-shaped fixed plate 107 and used for passing through the drive chain 305.

[0068] In this embodiment, the vertical dimensions of the lower surface slot 109 and the vertical rectangular hole 110 need to be as large as possible to ensure that the roller body 302 and the drive chain 305 accommodated therein are not accidentally bumped.

[0069] The number of drive chains 305 is two, each connected to two roller bodies 302 on the same side.

[0070] In this embodiment, the entire maintenance vehicle has a simple structure, so it can be manually driven without the need for additional motors, and among the four or eight roller bodies 302, two on one side can be rotationally driven to achieve short-distance movement.

[0071] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the spirit of the present application. These are modifications without creativity, and are protected by the patent law within the scope of the claims of the present application.
