Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.
As described in the background, in the case of stackers, it is common in the related art to employ safety tongs for rope breakage protection to prevent the cargo bed from falling. However, due to the problem of the installation accuracy of the safety tongs or the problem of the straightness of the rail of the stacker, when the cargo bed ascends and descends along the rail, the safety tongs are easily contacted with the rail, so that the safety tongs malfunction, and the cargo bed is stuck at a certain height of the stacker, and the stacker malfunctions.
As shown in fig. 1 and 2, fig. 1 is a front view of a brake mechanism according to an embodiment of the present application. Fig. 2 shows a side view of the braking mechanism of the embodiment of the present application. The braking mechanism of the embodiment of the application is applied to the stacking machine and comprises a mounting seat 100, safety tongs 200 and at least two guide pieces 300. The safety gear 200 is fixedly connected to the mounting base 100 and used for tightly holding the rail of the stacker so as to brake the cargo carrying platform of the stacker. The mounting 100 and the safety gear 200 are movably connected to the cargo bed in a floating direction D. At least two guide members 300 are arranged on the mounting seat 100 and are located on two opposite side surfaces of the rail of the stacker, that is, the rail is clamped between the at least two guide members, the guide members 300 are used for guiding the safety gear to lift along the rail, so that when the guide members 300 located on one side of the rail are abutted by the rail, the safety gear 200 can be driven by the mounting seat 100 to move along the floating direction D, and the safety gear 200 is prevented from contacting the rail.
The braking mechanism of the embodiment of the application is installed on a cargo carrying platform of the stacker, and when the cargo carrying platform goes up and down, at least two guide pieces 300 can guide the safety tongs to go up and down along the rail of the stacker. Moreover, the mounting seat 100 and the safety gear 200 are movably connected to the cargo carrying platform along a floating direction D, and the at least two guide members 300 are arranged on the mounting seat 100, so that when the guide member 300 on one side of the rail is abutted by the rail, the safety gear 200 can be driven by the mounting seat 100 to move along the floating direction D, so that the safety gear 200 is adapted to the change of the straightness of the rail, and the occurrence of misoperation of the safety gear 200 to cause the cargo carrying platform to be stuck is avoided.
It can be understood that, due to some reasons such as the breakage of a steel wire rope or a chain, the breakage of a lifting motor or a speed reducer and the like, a cargo carrying platform of the stacker drops rapidly, once the dropping speed of the cargo carrying platform exceeds a threshold value, the speed limiter is triggered, and the speed limiter pulls the clamp body of the safety clamp 200 to clamp the track to realize braking. It should be noted that the shape, structure and operation principle of the safety gear 200 according to the embodiment of the present application can be the products well-known in the art, and will not be described in detail herein.
In one embodiment, the floating direction D in which the mounting 100 and the safety gear 200 are movable relative to the cargo bed is perpendicular to the extension direction of the rails.
In this embodiment, the guide 300 is engaged with the rail when the cargo bed is not dropped rapidly, for example, the guide 300 is in sliding contact or rolling contact with the rail. Meanwhile, the safety gear 200 does not tightly hold the rail, but always keeps a set gap with the rail.
When the straightness of the rail does not meet the requirement, that is, a certain part of the rail is raised, and the cargo bed moves to the raised area, if the safety gear 200 does not move along the floating direction D, the safety gear 200 may accidentally contact the raised area of the rail when moving to the raised area, and the safety gear 200 may malfunction.
Referring to the braking mechanism of the embodiment of the present application, when the guide 300 on one side of the rail is abutted by the rail, the mounting seat 100 can drive the safety gear 200 to move along the floating direction D, and the floating direction D is perpendicular to the extending direction of the rail, so that the safety gear 200 moves along the floating direction D to avoid the protruding region of the rail. That is to say, when the cargo bed is in a normal operation state, the clamp body of the safety clamp 200 will not contact with the rail all the time, so as to avoid the problem of misoperation of the safety clamp 200.
Of course, in other embodiments, the floating direction D may not be perpendicular to the extending direction of the rail, for example, the floating direction D forms an angle with the extending direction of the rail, and the angle may be about 85 degrees or about 95 degrees. Those skilled in the art can design the relative position relationship between the floating direction D and the extending direction of the rail according to the specific shape of the rail and the specific shape of the safety gear 200, and it is sufficient that the safety gear 200 moves along the floating direction D to avoid the convex region of the rail.
With continued reference to fig. 1, in an embodiment, the braking mechanism further includes a guide rail 400 and a slider 500, the guide rail 400 is fixedly connected to the cargo bed and extends along the floating direction D, and the slider 500 is fixedly connected to the mounting base 100 and/or the safety gear 200 and forms a sliding pair with the guide rail 400.
In the present embodiment, the specific limitation of the movable manner of the mounting seat 100 and the safety gear 200 relative to the cargo bed is realized by the way that the guide rail 400 and the sliding block 500 form a moving pair. By arranging the guide rail 400 to extend along the floating direction D and designing the slider 500 to form a moving pair with the guide rail 400, the straightness of movement of the safety gear 200 can be ensured, and it is better ensured that the safety gear 200 does not come into contact with the rail in a normal state.
The slider 500 may be disposed on the mounting seat 100, on the safety gear 200, or on both the mounting seat 100 and the safety gear 200.
