Summary of the application

In the industrial production field, lifting equipment is generally adopted to carry out high lifting operation on materials, a hoist driven by a hoist has the advantages of compact structure, small occupied area, relatively low cost and the like, and is generally applied to production operation environments such as a mixing plant and the like so as to realize lifting operation of a lifting bucket by connecting a steel wire rope of the hoist with the lifting bucket. Wherein, because wire rope's life is usually shorter, wearing and tearing easily in long-term use, very easily take place the rope phenomenon of breaking when wearing and tearing reaches certain degree, and then lead to the whole whereabouts of elevator bucket, very easily take place the incident. Although relevant requirements for maintenance and replacement of the steel wire rope are met in relevant laws and regulations, real-time monitoring of the abrasion state of the steel wire rope is difficult to achieve in the actual production process, and operators cannot replace the steel wire rope in time easily due to forgetting or other objective reasons, so that great potential safety hazards exist in the use process of the elevator.

In order to prevent falling accidents caused by loosening of the steel wire rope in the use process of the elevator, a plurality of lifting mechanisms additionally provided with anti-falling systems are provided in the related art, and the anti-falling systems are formed by sensing equipment, a driving mechanism, an electric control system and the like so as to keep the lifting hopper fixed when the steel wire rope is loosened, however, the anti-falling systems in the scheme are relatively complex in structure and control, the corresponding elevator structures, the electric control system and the like are required to be specially designed, the cost is high, and popularization and application are not facilitated.

Some embodiments of the fall arrest elevator arrangement and the mixing plant according to the solutions of the utility model are provided below.

In one embodiment of the first aspect of the present utility model, there is provided a fall arrest elevator arrangement 100, as shown in fig. 1, the fall arrest elevator arrangement 100 comprising a hoist rail 1, a hoist assembly 2, and a fall arrest hitch assembly 3. The lifting guide rail 1 is provided with a plurality of anti-falling cross beams 11, and the anti-falling cross beams 11 are arranged at intervals in the lifting direction of the lifting guide rail 1. The hoisting assembly 2 comprises a hoisting mechanism 21 and a hoisting bucket mechanism 23, the hoisting mechanism 21 and the hoisting bucket mechanism 23 are correspondingly arranged on one side of the hoisting guide rail 1, the hoisting mechanism 21 is connected with the hoisting bucket mechanism 23 through a steel wire rope 22, and the hoisting bucket mechanism 23 and the hoisting guide rail 1 form guiding cooperation so as to realize lifting operation of the hoisting bucket mechanism 23 relative to the hoisting guide rail 1 through winding and unwinding the steel wire rope 22 by the hoisting mechanism 21. The anti-falling hanging component 3 is arranged on the lifting hopper mechanism 23 at a position opposite to the lifting guide rail 1, and the anti-falling hanging component 3 is rotationally connected with the lifting hopper mechanism 23 and is in sliding connection with the steel wire rope 22. In the initial state, the anti-falling hanging component 3 is under the tensile force of the steel wire rope 22, and a certain interval is kept between the anti-falling hanging component 3 and the lifting guide rail 1; when the steel wire rope 22 is loose, the anti-falling hanging component 3 can rotate relative to the lifting hopper mechanism 23 and form hanging fit with the corresponding anti-falling cross beam 11 on the lifting guide rail 1, so that the lifting hopper mechanism 23 is hung on the anti-falling cross beam 11 through the anti-falling hanging component 3, and therefore the lifting hopper mechanism 23 is prevented from falling, and an anti-falling effect is achieved.

It can be understood that under the normal state, the wire rope 22 keeps a straight state under the action of the hoisting mechanism 21 and generates a certain pulling force on the anti-falling hooking component 3, so that a certain distance is kept between the anti-falling hooking component 3 and the lifting guide rail 1, and interference to the normal lifting operation of the lifting bucket mechanism 23 is prevented. The loosened state of the wire rope 22 includes a state in which the wire rope 22 is disconnected, and also includes a state in which the wire rope 22 is not disconnected but the traction is lost (for example, a case in which the hoisting mechanism 21 fails to cause free payout).

It should be noted that, in practical applications, the lifting rail 1 has a certain thickness (in fig. 1, only simplified lines are used to replace the lifting rail 1, and the thickness is not shown), and the anti-falling beam 11 may be disposed at a side of the lifting rail 1 or a position away from the lifting bucket mechanism 23 according to circumstances, for example, the anti-falling beam 11 is located between two parallel lifting rails 1. Because the lifting hopper mechanism 23 only contacts with the outer surface of the lifting guide rail 1 facing the lifting hopper mechanism 23 when being matched with the lifting guide rail 1, in the normal lifting process, the lifting hopper mechanism 23 can be prevented from contacting with the lifting hopper mechanism 23 as long as the anti-falling cross beam 11 does not protrude to the side close to the lifting hopper mechanism 23 or the anti-falling cross beam 11 and the lifting hopper mechanism 23 are arranged in a staggered manner or the lifting hopper mechanism 23 is provided with a structure for avoiding the anti-falling cross beam 11, so that interference to lifting operation is avoided. The number of the anti-falling cross beams 11 can be set according to the height of the lifting guide rail 1 and the lifting range of the lifting bucket mechanism 23, and the distance between the adjacent anti-falling cross beams 11 can be set according to specific use requirements.

According to the anti-falling elevator device 100 in the embodiment, the anti-falling hanging component 3 is added, so that when a wire rope loosens, the anti-falling hanging component 3 and the anti-falling cross beam 11 on the lifting guide rail 1 form hanging fit to emergently fix the lifting bucket mechanism 23, and casualties and equipment property loss caused by falling accidents are prevented, and potential safety hazards are effectively reduced; meanwhile, the anti-falling hooking component 3 is simple in structure, does not need a complex driving system and an electric control system, only needs to be simply modified from the existing hoisting machine, is relatively low in cost and is easy to popularize and apply.

In a further embodiment of the present utility model, as shown in fig. 1 and 2, the fall arrest hitch assembly 3 includes a hitch member 31, a resilient return member 32, and a tightening mechanism 33. The hanging piece 31 is rotationally connected with the lifting bucket mechanism 23; the top end of the hanging piece 31 is provided with a first hook 311, and the opening of the first hook 311 faces the direction of the lifting guide rail 1; one end of the elastic restoring piece 32 is connected with a part of the hitching piece 31 positioned below the rotation center, and the other end of the elastic restoring piece 32 is connected with the lifting bucket mechanism 23. The tension mechanism 33 is disposed corresponding to the hitching member 31, one end of the tension mechanism 33 is connected to a portion of the hitching member 31 located above the center of rotation, and the other end is slidably connected to a section of the wire rope 22 remote from the lifting rail 1. Wherein the resilient return member 32 includes, but is not limited to, a spring as shown in fig. 2.

It will be appreciated that the wire rope 22 of the hoisting mechanism 21 is reeved around the rotating part of the hoisting hopper mechanism 23 and back onto the rotating part of the hoisting mechanism 21, thus forming two lengths of wire rope 22 turned back, i.e. a length close to the hoisting rail 1 and a length far from the hoisting rail 1.

In a normal state, as shown in fig. 2, the wire rope 22 is in a straightened state, the wire rope 22 can be wound and unwound relative to the tensioning mechanism 33, and a pulling force away from the lifting guide rail 1 is generated on the tensioning mechanism 33; the hitching member 31 is in a position spaced from the lifting rail 1 by the tightening mechanism 33 (i.e. the first position shown in fig. 2), at which time the elastic return member 32 is in a stretched state and has a tendency to resume a contracted state. When the wire rope 22 is loosened, as in the example in fig. 3, the tension of the wire rope 22 to the tensioning mechanism 33 disappears, and the tensioning mechanism 33 cannot continuously tension the hanging piece 31, at this time, the hanging piece 31 rotates under the elastic force of the elastic resetting piece 32, so that the first hook 311 rotates in a direction approaching to the first guide rail, and in the second position shown in fig. 3, the first hook is in hanging fit with a corresponding anti-falling beam 11, so that the lifting bucket mechanism 23 is integrally hung on the anti-falling beam 11 through the hanging piece 31, and a falling accident is prevented.

Further, a plurality of first hooks 311 can be arranged on the hanging piece 31, the plurality of first hooks 311 are connected to the top of the hanging piece 31, can be arranged side by side or are arranged at a certain included angle, can form hanging fit with the anti-falling cross beam 11 through the plurality of first hooks 311, and can effectively improve the strength and stability of the hanging fit.

In a further embodiment of the utility model, as shown in fig. 2 and 4, the tightening mechanism 33 includes a tightening piece 331. The tensioning piece 331 is arranged corresponding to the hanging piece 31, a first connecting piece 332 is arranged at one end of the tensioning piece 331 far away from the hanging piece 31, and the first connecting piece 332 is in sliding connection with the corresponding steel wire rope 22; the tensioning piece 331 is close to the one end of hitching piece 31 and is equipped with the second connecting piece 333, and the second connecting piece 333 is connected with hitching piece 31, and the tie point of second connecting piece 333 and hitching piece 31 is located the position that is close to first couple 311 on hitching piece 31 to keep away from hitching piece 31 for the rotation center of hoisting bucket mechanism 23, and then increase arm of force length plays laborsaving effect. Correspondingly, the connection point of the elastic restoring piece 32 and the hanging piece 31 is positioned on the hanging piece 31 near the bottom end, so that the stretching length of the elastic restoring piece 32 can be increased, and the elastic force effect is enhanced.

Further, the first connector 332 may include a connecting sliding sleeve 3321 or a connecting sliding ring 3322. As illustrated in fig. 4, the first connecting member 332 specifically takes the form of a connecting sliding sleeve 3321, the axial direction of the connecting sliding sleeve 3321 faces the lifting direction of the lifting mechanism 23, and the steel wire rope 22 away from the lifting rail 1 passes through the connecting sliding sleeve 3321 and abuts against the inner side wall of the connecting sliding sleeve 3321 so as to generate a tensile force on the hanging member 31 away from the lifting rail 1 through the connecting sliding sleeve 3321 and the tensioning member 331. The contact area of the connecting sliding sleeve 3321 and the steel wire rope 22 is relatively large, so that the abrasion condition of the steel wire rope 22 in the using process can be effectively reduced.

As illustrated in fig. 5, the first connecting member 332 specifically takes the form of a connecting slip ring 3322, and the connecting slip ring 3322 has the advantages of simple structure, light weight, easy processing, low cost, and the like. According to specific use requirements, a locking structure capable of opening and closing the connecting sliding ring 3322 can be further arranged on the connecting sliding ring 3322 so as to facilitate the assembly of the connecting sliding ring 3322 and the steel wire rope 22.

Further, in one implementation, as shown in fig. 4, the second connector 333 includes a connection male shaft 3332 and a second hook 3333. The connection protruding shaft 3332 is transversely connected to the hanging piece 31, the second hook 3333 is connected to one end of the tightening piece 331 close to the hanging piece 31, and the tightening piece 331 is hung on the connection protruding shaft 3332 through the second hook 3333, so that a pulling force away from the lifting guide rail 1 is applied to the hanging piece 31 through the hanging fit of the second hook 3333 and the connection protruding shaft 3332, and the hanging piece 31 is rotated until the first hook 311 keeps a certain distance from the lifting guide rail 1, so that interference to normal lifting operation is prevented. Through setting up the second couple 3333 can convenient assembly and dismantlement, dismouting operation is comparatively simple, when taking place other special conditions, can take off the second couple 3333 from connecting protruding axle 3332 earlier, makes first couple 311 articulate on the anti-falling crossbeam 11 that corresponds on lifting rail 1, and lifting bucket mechanism 23 can keep temporarily to articulate fixedly to the maintenance operation is convenient.

Further, in another implementation, as shown in fig. 5, the second connecting member 333 includes a connecting pin 3331, and correspondingly, a connecting pin hole is formed on the hanging member 31 near the first hook 311, an adaptive pin hole is also formed on one end of the tightening member 331 near the hanging member 31, the two pin holes are aligned and matched, and the connecting pin 3331 penetrates into the pin holes on the hanging member 31 and the tightening member 331, so that the hanging member 31 is hinged to the tightening member 331. Unhooking phenomenon is difficult to take place between the articulated element 31 and the taut piece 331 of connection through connecting pin 3331, even take place to rock, phenomenon such as vibration in the use also can effectively connect, and connection stability is stronger.

Further, as shown in fig. 4 and 5, in the tensioning mechanism 33, the tensioning member 331 may be a rigid rod, and in the lifting process, the rigid rod may not be deformed such as stretched, bent, twisted, etc., the pulling direction of the hanging member 31 is always along the length extending direction of the rod, and the distance between the hanging member 31 and the wire rope 22 can be kept relatively fixed, so that the tensioning effect of the hanging member 31 is relatively stable.

Of course, the tension member 331 is not limited to the rigid rod, and in practical application, some flexible structures, such as flexible ropes, may be used according to the use requirement, preferably, the flexible ropes may be steel wire ropes, and may be deformed by bending or twisting to some extent, but not be stretched, so that the distance between the hanging member 31 and the steel wire rope 22 does not change greatly, and further, the distance between the hanging member 31 and the lifting guide rail 1 is kept within an allowable range, and the overall position is relatively stable. Of course, the flexible ropes can also adopt ropes with smaller stretching amplitude, and the first hook and the anti-falling cross beam can be kept at a sufficient distance so as not to interfere with each other. In addition, because the wire rope 22 is slidably connected with the first connecting member 332 of the tightening member 331, the wire rope 22 can slide up and down relative to the first connecting member 332 in the lifting process, and a certain displacement is inevitably generated by the tightening member 331 under the action of friction force, at this time, a certain deformation amount can be generated by the flexible rope, and a locking phenomenon is not easy to occur, so that adverse effects on lifting operation are prevented.

It should be noted that, the above is only a preferred implementation manner of the tension member 331, the tension member 331 is not limited to the rigid rod and the flexible rope, and other structural forms of the tension member 331, such as a plate, a tube, etc., may be adopted according to specific usage requirements, and will not be described herein.

In a further embodiment of the utility model, as shown in fig. 2 and 4, the tightening mechanism 33 further comprises a stop 34. The limiting piece 34 is arranged at a position on the lifting bucket mechanism 23 corresponding to the tensioning piece 331, one end of the limiting piece 34 is connected with the lifting bucket mechanism 23, and the other end of the limiting piece 34 is connected with the tensioning piece 331. By the acting force of the limiting member 34 on the tightening member 331, the tightening member 331 can be prevented from being displaced in the lifting direction under the friction force of the wire rope 22 during the lifting process, so that the positions of the tightening member 331 and the hitching member 31 can be kept relatively stable.

The shape and size of the limiting member 34 may be set according to specific use requirements, preferably, the limiting member 34 may be a rigid rod, which may generate a tensile force on the tensioning member 331 when the wire rope 22 ascends, and generate a pushing force on the tensioning member 331 when the wire rope 22 descends, that is, the limiting member may play a limiting role in both the ascending and descending processes of the wire rope 22.

Preferably, the two ends of the limiting piece 34 are respectively connected with the tensioning piece 331 and the lifting bucket mechanism 23 in a rotating way, so that the limiting piece can be matched with the rotation of the hanging piece 31 after the steel wire rope 22 is loosened, and the hanging cooperation of the hanging piece 31 and the anti-falling cross beam 11 is prevented from being influenced due to the blocking phenomenon.

Preferably, the limiting member 34 is disposed parallel to the straightened wire rope 22, and the tensioning member 331 is capable of keeping the vertical state with the limiting member 34 and the straightened wire rope 22, and the stress state is better.

In a further embodiment of the utility model, as shown in fig. 1 to 3, the lift bucket mechanism 23 comprises a lift bucket base 231, a pulley mechanism 232 and a lift bucket 233. The lifting bucket seat 231 is located at the side of the lifting guide rail 1, and a plurality of roller mechanisms 2311 are arranged at the side of the lifting bucket seat 231 facing the lifting guide rail 1 so as to form rolling fit with the lifting guide rail 1 through the roller mechanisms 2311; the pulley mechanism 232 is arranged at a position on the lifting bucket seat 231 near the top, and the steel wire rope 22 is wound on the pulley mechanism 232 to form a movable pulley structure form so as to cooperate with the winding and unwinding operation of the winding mechanism 21 on the steel wire rope 22. When the hoisting mechanism 21 works, the steel wire rope 22 enables the lifting bucket base 231 to roll upwards or downwards relative to the lifting guide rail 1, so that friction resistance in the lifting process of the lifting bucket mechanism 23 can be effectively reduced, and the lifting process is smoother. The lifting hopper 233 is connected to one side of the lifting hopper base 231, which is opposite to the lifting guide rail 1, and is used for loading materials, so that the lifting hopper 233 is driven to lift by lifting of the lifting hopper base 231, and lifting operation of the materials is realized. Wherein, the bottom of the lifting hopper 233 is provided with a hopper door 2331 which can be opened or closed to facilitate loading and unloading.

Further, according to the specific structural form of the bucket seat 231, the anti-falling hanging component 3 may be directly connected to the bucket seat 231, or as in the examples of fig. 2 and 3, by providing the connection lug 2312 at the top of the bucket seat 231, the anti-falling hanging component 3 is rotationally connected to the connection lug 2312, and as in the example of the figure, the rotation center of the hanging piece 31 is provided on the connection lug 2312, so as to support and fix the anti-falling hanging component 3.

The tensioning piece 331 is arranged corresponding to the hanging piece 31, a first connecting piece 332 is arranged at one end, close to the steel wire rope 22 far away from the lifting guide rail 1, of the tensioning piece 331, the first connecting piece 332 is specifically connected with a sliding sleeve 3321, and the steel wire rope 22 penetrates through the sliding sleeve 3321 and forms sliding connection; the tension member 331 is provided with a second connecting member 333 at one end close to the hanging member 31, the second connecting member 333 adopts a connecting protruding shaft 3332 and a second hook 3333, the connecting protruding shaft 3332 is transversely connected to the hanging member 31 at a position close to the first hook 311, the second hook 3333 is connected with the tension member 331 and is hung on the connecting protruding shaft 3332, and a pulling force far away from the lifting guide rail 1 is applied to the hanging member 31 through the hanging fit of the second hook 3333 and the connecting protruding shaft 3332, so that the hanging member 31 is rotated to the first hook 311 and the lifting guide rail 1 to keep a certain distance, and interference to normal lifting operation is prevented. The tensioning member 331 specifically adopts a structure of a rigid rod body, and is not deformed such as stretched, bent, twisted and the like in the lifting process, so that the strength and the stability are better.

As shown in fig. 2 and 4, the limiting member 34 is a rigid rod member, one end of the limiting member 34 is rotatably connected to the bucket base 231, and the other end is rotatably connected to the tension member 331. By the acting force of the limiting member 34 on the tightening member 331, the tightening member 331 can be prevented from being displaced in the lifting direction under the friction force of the wire rope 22 during the lifting process, so that the positions of the tightening member 331 and the hitching member 31 can be kept relatively stable. The limiting piece 34 is disposed parallel to the straightened wire rope 22, and the tightening piece 331, the limiting piece 34 and the straightened wire rope 22 can be kept in a vertical state, and the stress state is better.

As shown in fig. 1 and 2, the hoisting mechanism 21 is connected with the lifting bucket mechanism 23 through a steel wire rope 22, so that the lifting operation of the lifting bucket mechanism 23 is realized by winding and unwinding the steel wire rope 22 through the hoisting mechanism 21, and further, the material lifting of the lifting hopper 233 device is realized. In the initial state, the hanging piece 31 rotates to the first position shown in fig. 2 under the tensile force of the tensioning piece 331 and the steel wire rope 22, and a certain distance is kept between the hanging piece and the lifting guide rail 1; at this time, the elastic restoring member 32 is in a stretched state and has a movement tendency to restore a contracted state. When the wire rope 22 is loosened, as in the example in fig. 3, the tension of the wire rope 22 to the tensioning mechanism 33 disappears, and the tensioning mechanism 33 cannot continuously tension the hanging piece 31, at this time, the hanging piece 31 rotates under the elastic force of the elastic resetting piece 32, so that the first hook 311 rotates in a direction approaching to the first guide rail, and in the second position shown in fig. 3, the first hook is in hanging fit with a corresponding anti-falling beam 11, so that the lifting bucket mechanism 23 is integrally hung on the anti-falling beam 11 through the hanging piece 31, and a falling accident is prevented.

According to the anti-falling elevator device 100 in the embodiment, the anti-falling hanging component 3 is added, so that when a wire rope loosens, the anti-falling hanging component 3 and the anti-falling cross beam 11 on the lifting guide rail 1 form hanging fit to emergently fix the lifting bucket mechanism 23, and casualties and equipment property loss caused by falling accidents are prevented, and potential safety hazards are effectively reduced; meanwhile, the anti-falling hooking component 3 is simple in structure, does not need a complex driving system and an electric control system, only needs to be simply modified on the existing hoisting machine, is relatively low in cost and is easy to popularize and apply.

In a second aspect of the present utility model, as shown in fig. 1 and 6, a mixing station 500 is provided, where the mixing station 500 includes the anti-drop elevator apparatus 100 according to any of the above embodiments, so as to load a material through the lifting bucket mechanism 23 of the anti-drop elevator apparatus 100, and drive the lifting bucket mechanism 23 to lift through the lifting mechanism 21, so as to implement a lifting operation of the material. When the steel wire rope 22 of the hoisting mechanism 21 is loosened, the anti-falling hooking component 3 can rotate relatively, and form hooking cooperation with one anti-falling cross beam 11 corresponding to the hoisting guide rail 1, so that the hoisting bucket mechanism 23 is integrally hooked on the anti-falling cross beam 11, and the hoisting bucket mechanism 23 is prevented from falling.
