Description

Suspended crane handling device

The present invention provides the technical field of a high-altitude rail-type unmanned transport vehicle (OHT), in particular, it technically provides a suspended crane transport device, which is mainly provided with two sets of limited-slip differentials to drive four main transmission limited-slip differentials. The differential wheel allows a limited-slip differential wheel to be suspended in the air through a straight or arc blank rail section. Because the limited-slip differential allows the other limited-slip differential wheel to move continuously and steadily, the output will not slip or spin. , the overall handling device can have a simple structure, reduce costs, be easy to maintain, and have smooth rotation and operation.

Click, refer to Figure 8, which is a conventional invention patent application No. 109124616 "Suspension Handling Equipment". The independent items in the scope of the patent application include: "A track module 70, including a main Track 71 and a first track 711; wherein, the track module 70 defines a turning path P1 of the overhead crane extending from the main rail 71 to the first rail 711; and a differential overhead crane 60, which can It is movably installed on the track module 70, and the differential crane 60 includes: an operating mechanism 61, including two differential wheels 612 respectively located on opposite sides and connected to the two differential wheels. A driving unit 614 of 612; wherein when the differential crane 60 moves from the main track 71 along the When the crane turning path P1 moves to the first track 711, the drive unit 614 can drive the two differential wheels 612 to roll forward on the first track 711 at different rotational speeds; and The car body 62 is connected to the running mechanism 61 and suspended below the track module 70;...". This paragraph of claim 1 of the previous case must be combined with claim 2 of the previous case: "The drive unit includes two drive motors that can independently drive the two differential wheels, and when the When the differential crane moves from the main track to the first track along the steering path of the crane, the two drive motors can respectively drive the two differential wheels to rotate at different rotation speeds. Rolling forward on the first track." It must be combined with request item 3 of the previous case: "The drive unit includes: a differential, connected to the two differential wheels; and a drive motor, connected to the differential; wherein, when When the differential crane moves from the main track to the first track along the steering path of the crane, the drive motor can drive the two differential wheels in different directions through the differential. The rolling speed on the first track." In order to have a comprehensive understanding, claim 1 is an operating mechanism, including two differential wheels and a drive unit connected to the two differential wheels. The claim 2 is that the drive unit is two independent drive motors, and one drive motor drives a differential wheel. The claim 3 is that the drive unit is a differential connected to two differential wheels. Therefore, whether it is a differential or two drive motors, they will still have the problem of idling in the gap in the track, causing the problem of inability to output power. It is necessary to design "two complete sets of supplementary tracks, including power and control equipment". More Create a blank space on the track at the bifurcation to accommodate two sets of supplementary tracks for assembling the two sets of supplementary tracks to solve the problem of possible idling or no power output. On the other hand, power only relies on two wheels. Compared with four-wheel powered equipment, problems such as idling, slipping, and mistakes are more likely to occur.

Claim 1 of the patent application filed in the prior application "...wherein, the first track 711 is formed with a first disconnecting groove 721 on the crane turning path P1, and the track module 70 includes: a first A supplementary track 74 is installed on the first track 711 and is movably located in the first disconnecting groove 721 so as to be located on the crane turning path P1; and a first switching mechanism 75 is connected to the The first supplementary track 74, and the first switching mechanism 75 can drive the first supplementary track 74 to move between a first initial position and a linear position; wherein, when the first supplementary track 74 is in the first initial position, the position of the first supplementary track 74 corresponds to the first track 711; when the first supplementary track 74 is in the straight position, the first supplementary track 74 is in the straight position. The partial position of the type track 74 is on the straight path P2 of the overhead crane and is located between the main track 71 and the second track 73." This paragraph of the discussion in claim 1 of the previous case is all about the design and function of the first supplementary track 74. Why should the first supplementary track 74 and the second supplement be designed in claim items 1 and 8 of the previous case? The main reason for the track 76 is that the two drive motors 6141 and the two differential wheels 612 can adapt to changes in straight running and turning. However, a turning track or a turning track must be designed on a straight running track. If a straight track is designed on the road, there will inevitably be a straight gap without track section and a turning gap without track section. Therefore, the method of the previous case is to dynamically use the first supplementary track 74 or the second supplementary track 76 to fill it up in a timely manner. gap, so as to avoid the situation that one of the differential wheels 612 is idling and cannot transmit power. However, such complex design control is required at each branch point, and the cost will inevitably increase significantly, and any control point must be avoided. However, the addition of so many additional control devices also greatly increases the error rate.

It is known that the previous model only has a set of two driving wheels, so it can only be installed in the middle of the car body, and then a total of four driven wheels are installed on each side of the car. Their purpose can only be to support the car body and have no other function, and the power will slip. Or it can't help at all when idling. The power is only available on the two sides in the middle, not the front or rear. It is easy to make mistakes. However, the conventional differential only uses the conventional differential, so there will be slipping and idling. Problems such as the inability to output power.

The Limited Slip Differential (LSD) can ensure the power output of the driving wheels. The purpose of the Limited Slip Differential is to improve the conventional differential when the driving force output is too large or the ground is too slippery. Or one wheel is suspended in the air, causing one side of the driving wheel to slip, causing the other wheel to lose driving force at the same time, resulting in the vehicle being unable to get out of trouble or having poor tracking.

Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop an innovative structure that is more ideal and practical to meet the ardent expectations of consumers is also the goal and direction that relevant industries must work hard to develop breakthroughs.

The main purpose of the present invention is to provide a suspended crane handling device, which is mainly provided with two limited-slip differentials, and is extended from both sides of the limited-slip differential to two limited-slip differential wheels. The slip differential has a total of four transmission limited-slip differential wheels. When the running mechanism passes through the curved track, the limited-slip differential wheel can adjust the speed by itself due to the speed difference generated by the limited-slip differential. When it passes through the straight or arc blank track When one limited-slip differential wheel is suspended in the section, the other wheel of the same group of limited-slip differentials can continue to move smoothly and output without slipping and idling. This means that the other three non-suspended limited-slip differential wheels are located at Normal transmission power on straight or curved tracks does not require the use of other supplementary tracks and related components. The overall handling device can have a simple structure, reduce costs, easy maintenance, and smooth rotation.

In order to achieve the above object, the present invention provides a suspended overhead crane transportation device, which includes: a track module including a main track through a bifurcation point, a straight track, a straight blank rail section, a curved track and an arc blank rail.

The two limited-slip differentials total four transmission limited-slip differential wheels. When the running mechanism passes through the curved rail The limited-slip differential wheel of the track can adjust its speed by itself due to the speed difference generated by the limited-slip differential. When a limited-slip differential wheel is suspended in the straight or arc blank track section, the other limited-slip differential wheel of the same group will One wheel can continuously move smoothly and output without slipping or idling. This means that the other three non-hanging limited-slip differential wheels are located on straight or curved tracks to transmit power normally, without the need to use other supplementary tracks and their Related components, the overall handling device can be simple in structure, reduce costs, easy to maintain and operate smoothly.
