Description

Technical Field

[0001] The utility model relates to the technical field of logistics warehousing, in particular to a shuttle vehicle track changing maintenance mobile device. Background Art

[0002] In an automated warehouse, a shuttle system is one of the conveying devices used to transfer goods between different cargo entry and exit interfaces. In actual work, a long closed-loop running track with two straight side sections similar to a playground runway is often used, and sometimes a closed-loop running track with one straight side section is also used. The shuttle moves along the closed-loop running track, and the shuttle picks up goods from the receiving and delivery equipment at the cargo entry and exit interface or transfers the goods to the receiving and delivery equipment through the fork mechanism. The disadvantage of the above-mentioned shuttle system is that when a shuttle fails in the shuttle system, it is impossible to easily and quickly move the failed shuttle away from the closed-loop running track. The shuttles that have not failed in this solution operate normally, and the entire circular shuttle system needs to be stopped, and then the failed shuttle is repaired, resulting in a long shutdown time of the shuttle system due to maintenance, or hoisting work is required to move the shuttle that needs maintenance or overhaul away from the running track without affecting other shuttles.

[0003] For example, a running track capable of quickly transferring a shuttle vehicle in an existing disclosed circular shuttle vehicle system (CN113753459A) provides a technical solution in which a movable track capable of detaching from the closed-loop running track and carrying the shuttle vehicle is provided in the closed-loop running track, and a maintenance track capable of carrying the shuttle vehicle is provided outside the movable track, the movable track is movably supported on a transition track having a travel transfer end and a maintenance transfer end at both ends respectively and can reciprocate between the travel transfer end and the maintenance transfer end, and is further provided with a locking mechanism capable of locking the movable track on the transition track; when the movable track moves to the travel transfer end and is locked on the transition track, the movable track is engaged in the closed-loop running track and constitutes a part of the closed-loop running track, and when the movable track moves to the maintenance transfer end and is locked on the transition track, the movable track can be docked with the maintenance track, so that the shuttle vehicle can move from the movable track to the maintenance track, and the running track enables a shuttle vehicle that has a malfunction to be quickly moved away from the closed-loop running track.

[0004] However, since the movable track of the above technical solution needs to be embedded in the closed-loop running track and constitutes a part of the closed-loop running track, so that the shuttle car can detach from the closed-loop running track and reciprocate between the travel transfer end and the maintenance transfer end of the transition track, it does not solve the problem that when the shuttle car fails and stops at any position in the track, the shuttle car needs to be pushed and transferred, or a crane is needed to move the failed shuttle car away from the running track; or the closed-loop track is made of movable tracks, which increases the area occupied by the track.

The limit plate is used to adjust the distance between the limit plate and the connecting plate by a screw, and the limit plate can extend to abut against the top end surface of the guide rail rod to form a roadblock to limit and stop the movable track.

[0009] Furthermore, the movable track includes: two oppositely arranged reversing tracks, connecting rods installed inside the reversing tracks and at intervals along the extension direction of the reversing tracks.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] In view of the difficulty in effectively driving the shuttle car away from the running track 9 in the prior art, the applicant has developed a shuttle car track change maintenance mobile device, such as Figure 1-4As shown, it includes: an inspection transition track 1, a movable track 2 movably supported on the inspection transition track 1, and the extension direction of the movable track 2 and the running track 9 at the connection point is consistent, and the height between the two is consistent, the movable track 2 can move along the inspection transition track 1 until it is against the running track 9, and the movable track 2 drives the shuttle vehicle to move along the inspection transition track 1 through the rollers 4 provided at the bottom, so that the shuttle vehicle drives away from the movable track 2, and the guide extension direction of the inspection transition track 1 is perpendicular to the guide extension direction of the movable track 2; a limit seat 3 for positioning the movable track 2 is detachably installed in the inspection transition track 1.

[0022] The maintenance transition track 1 includes: a plurality of guide rods 11 arranged in parallel and at intervals (in the present embodiment, three guide rods 11 are preferably used in parallel and at intervals) and support seats 12 for supporting the corresponding guide rods 11; the support seats 12 are arranged in sequence at intervals at the bottom of the corresponding guide rods 11 to support the guide rods and the movable tracks 2 on the guide rods, and stop blocks 13 (nuts 7 set on the guide rods 11 are tightened) for limiting the operation of the movable tracks 2 are installed at both ends of the guide rods 11.

[0023] In the embodiment, the limit seat 3 is specifically installed in the guide rail rod 11 located at the two ends of the outer side, and the limit seat 3 includes: a vertical rod 31 set on the ground, a connecting plate 32 threadedly set on the vertical rod 31, and the vertical rod 31 is located at the four corners of the end wall of the connecting plate 31. The limit plate 33 is detachably installed on the connecting plate 32 (the end facing away from the ground). The limit plate 33 is adjusted by a screw 34 to adjust the distance between the limit plate 33 and the connecting plate 32, that is, the limit plate 33 performs a reciprocating vertical lifting motion, so that the limit plate 33 can extend to abut against the top end surface of the guide rail rod 11 to form a roadblock, thereby realizing the limit locking of the movable track 2.

[0024] The movable track 2 includes: two oppositely arranged reversing tracks 21, and connecting rods 22 are installed at intervals in the reversing tracks 21 and along the extension direction of the reversing tracks 21. In order to ensure the tight connection between the two reversing tracks 21, the reversing tracks 21 and the connecting rods 22 are vertically arranged to form an integrated structure. The rollers 4 are relatively installed at the bottom of the corresponding connecting rods 22, and the rollers 4 on any connecting rod 22 are relatively arranged at the outer end wall of the reversing track 21. For example, in this embodiment, three connecting rods 22 are fixed at the bottom of the reversing track 21, and a roller 4 is provided at both ends of the reversing track 21. That is, two rollers 4 are provided on one connecting rod 22, and rollers 4 are provided on at least the connecting rods 22 located at both ends of the reversing track 21.

[0025] In order to save space and ensure the reliability of the movable track 2, the number of connecting rods 22 is consistent with the number of guide rails 11, that is, as recorded in the present application, the number of connecting rods 22 and the number of guide rails 11 are both three.

[0026] In order to effectively and quickly dock the movable track 2 with the running track 9, a U-shaped stopper 5 for limiting the moving distance of the movable track 2 is movably installed in the maintenance transition track 1, and the movable track 2 can move along the maintenance transition track 1 until it abuts against the end wall of the U-shaped stopper 5. Specifically, a section of movable track 6 is also provided between the guide rails 11, and the movable track 6 is consistent with the extension direction of the guide rails 11, and the bottom end of the U-shaped stopper 5 (that is, the end in contact with the movable track 6) extends outward (that is, in the same direction as the extension direction of the movable track 6), and the extension distance of the extended end of the U-shaped stopper 5 is less than the overall setting length of the movable track 6. It should be noted that the distance D from the end face of the top of the extended section of the U-shaped stopper 5 to the ground is ≤ the distance L from the top end face of the guide rail 11 to the ground, thereby ensuring that the movable track 2 abuts against the U-shaped block; the U-shaped stopper 5 is moved or locked in the movable track 6 by the provided bolts.

[0027] In order to facilitate manual operation of the movable track 2, a movable pull ring 8 is installed on the movable track 2, but the present application is not limited to this technical solution. The movable track 2 can also be driven to move by an external telescopic rod or a screw rod can be provided on the maintenance transition track 1, and a screw nut 7 is installed on the movable track 2 to drive the movable track 2 to run along the maintenance transition track 1.

[0028] Operation principle: when it is necessary to drive the shuttle car with maintenance away from the running track 9, it is necessary to first build the maintenance transition track 1 and the U-shaped stopper 5, and then build the movable track 2 on the maintenance transition track 1, and then move the movable track 2 until it is against the U-shaped stopper 5. At this time, the movable track 2 is against the running track 9, and the shuttle car can drive away (or be manually pushed away) from the running track 9 to the movable track while maintaining the original running state; then move the movable track 2 along the set path of the maintenance transition track 1 to separate the movable track 2 from the running track 9, and limit and fix the movable track 2 through the provided limit seat 3, so that the workers can inspect the shuttle car and ensure that the remaining shuttle cars can reciprocate along the running track 9 as usual; when the shuttle car has completed the inspection, the limit seat 3 is removed, so that the movable track 2 runs along the maintenance transition track 1 until it merges with the running track 9 again, and the shuttle car re-enters the running track 9 along the movable track 2.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
