[0029] Example 1

[0030] The overhead crane height-to-low position transfer device disclosed in this utility model is described below with reference to the accompanying drawings. Figure 1 As shown, the overhead crane high-low position transfer device includes an overhead crane receiving mechanism 100, a high position track mechanism 200, and a lifting drive mechanism 300 that drives the overhead crane receiving mechanism 100 to move up and down so that the two receiving tracks 110 of the overhead crane receiving mechanism 100 are connected to the two high position tracks 210 of the high position track mechanism 200.

[0031] As attached Figure 2 As shown, the overhead crane receiving mechanism 100 includes two parallel receiving rails of equal height, which are connected by a set of C-shaped fixing frames 120. Connecting heads 130 for connecting to the lifting drive mechanism 300 are respectively provided on the outer sides of the two receiving rails 110.

[0032] As attachedFigure 1 , attached Figure 3 As described above, the high-level rail mechanism 200 includes two high-level rails 210 corresponding to the receiving rails 110 respectively, and the high-level rails 210 can be fixed on the ceiling by the way of suspension. The high-level rail mechanism 200 is two and the gap is arranged at both ends of the crown block receiving mechanism 100.

[0033] The lifting driving mechanism 300 can be a known feasible mechanism, which is arranged above the high-level rail mechanism 200 and located between the two high-level rail mechanisms 200. The structure of the lifting driving mechanism 300 can be designed according to the needs, and in the preferred embodiment, as shown in the attached Figure 4 The lifting driving mechanism 300 includes a base plate 310, which is fixed horizontally below the ceiling, and a rotating shaft 320 arranged rotatably at the bottom of the base plate 310 and extending horizontally close to one side of the base plate 310. The rotating shaft is parallel to the receiving rail and connected to a driving assembly 330 for driving the rotation of the rotating shaft. The driving assembly 330 is, for example, a structure composed of a driving motor and a speed reduction mechanism. Four synchronous wheels 340 are arranged concentrically on the rotating shaft 320 and rotate synchronously with the rotating shaft 320. Two lifting belts 350 are wound on each synchronous wheel 340, and then directly extended downward by the synchronous wheel 340 and connected to two connecting heads 130 on one side of the crown block receiving mechanism 100. The other two lifting belts 350 are wound around the top of a deflection wheel 360 away from the rotating shaft 320 and then connected to two connecting heads 130 on the other side of the crown block receiving mechanism 100. Moreover, when the rotating shaft 320 rotates, the lifting height of the ends of the four lifting belts 350 is the same.

[0034] As shown in the attached Figure 2 , attached Figure 3 As shown in the attached

[0035] The guide seat 150 is provided on the outer side of each receiving rail 110 and near the end of the receiving rail 110. The guide hole 151 on the guide seat 150 can be a round hole. More preferably, in order to facilitate efficiency and avoid interference, the guide hole of the guide seat 150 is an oblong hole extending in the vertical direction. When the receiving rail 110 stops moving downward, the telescopic rod 510 abuts against the top of the guide hole.

[0036] As attached Figure 4 As shown, a first sensor 370 is provided at the lifting drive mechanism, and a trigger 140 matching the first sensor 370 is provided on the overhead crane receiving mechanism 100. The trigger 140 is specifically installed on the side of a fixed frame 120. When the overhead crane receiving mechanism 100 is lifted to a certain height, the first sensor 370 can detect the trigger 140.

[0037] As attached Figure 2 Appendix Figure 4 As shown, a guide cylinder 160 is provided on the overhead crane receiving mechanism 100. The guide cylinder 160 is provided with an inverted frustum-shaped or funnel-shaped guide hole. The axis of the guide hole extends in the vertical direction. The lifting drive mechanism 300 is provided with a vertical guide rod 380 that matches the guide hole. So when the overhead crane receiving mechanism 100 is raised to a predetermined height, each of the vertical guide rods 380 is inserted into the guide cylinder 160 that is concentric with it, thereby limiting the horizontal position of the overhead crane receiving mechanism 100.

[0038] When the overhead crane transfer device is in use, as shown in the attached Figure 5 As shown, the crane receiving mechanism 100 can be lowered to a suitable position below the high-level track 210 and close to the ground by the lifting drive mechanism 300. Then, the crane 400 on the ground is moved onto the receiving track 110. Then, the lifting drive mechanism 300 lifts the crane receiving mechanism 100 upward so that the receiving track 110 is connected with the high-level track 210. After the receiving track 110 is connected with the high-level track 210, the crane 400 is transferred from the receiving track 110 to the high-level track 210.

[0039] Furthermore, the receiving rail 110 can be moved to a position higher than the upper rail first, and then the receiving rail can be moved down. At the same time as the receiving rail moves down, the telescopic rod of the telescopic rod assembly moves towards the guide seat. Simultaneously, by matching the telescopic speed of the telescopic rod with the downward speed of the receiving rail 110, when the receiving rail moves down to dock with the upper rail, the conical end of the telescopic rod is inserted into the guide hole.

[0040] When the trolley 400 on the high-level track 210 needs to be transferred to the ground, the receiving track 110 can be first docked with the high-level track 210, and then the trolley 400 is moved from the high-level track 210 to the receiving track 110. After the receiving track 110 is lowered to a predetermined height by the lifting driving mechanism 300, the trolley 400 can be moved out of the receiving track 110.

[0041] Further, before the first sensor 370 detects the trigger 140, the lifting driving mechanism 300 drives the trolley receiving mechanism 100 to move upward at a faster speed, and after the first sensor 370 detects the trigger 140, the lifting driving mechanism 300 drives the trolley receiving mechanism 100 to move upward at a slower speed. The specific speed of upward movement can be designed as needed, which is not limited here. This can effectively ensure the lifting efficiency and effectively avoid the problem of the trolley receiving mechanism 100 hitting the top due to the inertia caused by the too fast upward movement speed.

[0042] Further, a second sensor 390 is arranged above the first sensor 370 on the lifting driving mechanism 300. At any time before the trolley receiving mechanism 100 continues to move upward to the target position, if the second sensor 390 detects the trigger 140, an alarm is issued, and the driving motor is stopped or controlled to drive the trolley receiving mechanism 100 to move downward, thereby minimizing the risk of equipment safety problems in abnormal situations.

[0043] Finally, a blocker (not shown in the figure) is arranged at both ends of the upper track to block the trolley. The blocker is arranged at one end of the upper track close to the trolley receiving mechanism. The structure of the blocker can be designed as needed. For example, in one embodiment, the driver includes a blocking block that is slidably arranged on a support outside the upper track. The blocking block is higher than the top surface of the upper track and is connected to a horizontal driver that drives it to translate in a direction perpendicular to the upper track. The horizontal driver can be a cylinder or an electric cylinder or other available devices. When blocking is needed, the horizontal driver drives the blocking block to move above the top surface of the upper track or to the inside of the upper track. When blocking is not needed, the horizontal driver drives the blocking block to move to the outside of the upper track. Of course, the blocker can also adopt other available structures, which are not limited here.

[0044] When the trolley transfer is not needed, the blocker blocks the trolley from moving to the end of the upper track close to the trolley receiving mechanism, thereby effectively avoiding the risk of the trolley falling from the upper track and improving safety.
