Detailed Description
In order to make the technical scheme of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.
Referring to fig. 1-6, an embodiment of the present invention provides a weighing rope mechanism, which comprises a rope body 1, a winding shaft 2, a connecting piece 3 and a resistance mechanism; the connecting piece 3 is arranged at the bottom of the winding shaft 2, the rope body 1 is arranged in the connecting piece 3 in a penetrating manner, and a weighing module for weighing the weight of the rope body 1 is arranged in the connecting piece 3; the resistance mechanism does not operate when the rope 1 is loaded, and applies resistance to the rope 1 in the connector 3 when the rope 1 is unloaded.
Specifically, the rope body 1 is a rope, one end of the rope is fixed on the winding shaft 2, and the end head of the other end is used for bearing a weight, such as a semi-finished product in industrial production; the winding shaft 2 is a part of an RGV crane, a power mechanism is generally arranged on the RGV crane to drive the winding shaft 2 to rotate, so that winding and unwinding operation is carried out on the rope body 1 wound on the winding shaft 2, further, a weight borne on the rope body 1 is driven to lift, and then the semi-finished product can be transported by matching with the movement of the RGV crane; the maximum bearing capacity of the weighing rope mechanism can be determined according to the material of the rope body 1 and the setting mode of the winding shaft 2, and in the working process of the weighing rope mechanism, when the load on the rope body 1 exceeds the maximum bearing capacity, the danger coefficient is higher, so that a weighing module is required to be arranged for weighing the load of the rope body 1; the above are prior art and are not described in detail. The innovation point of the embodiment of the invention is that a connecting piece 3 (which can be fixedly connected or detachably connected) is arranged at the bottom of a winding shaft 2, and a rope body 1 is penetrated in the connecting piece 3, so that a weight borne on a rope can be weighed through a weighing module in the connecting piece 3 (the weighing module can be a weighing pulley in the prior art, and part of the weighed weight belongs to the weight of the rope body 1 and can be ignored), thereby determining whether the load of a weighing rope mechanism exceeds the maximum bearing capacity of the weighing rope mechanism; in the process of the load operation of the rope body 1, the winding shaft 2 rotates to drive the rope body 1 to be wound and unwound, at the moment, the rope body 1 has a certain tensioning force, and when the winding shaft 2 rotates, the rope body 1 can be tightly wound on the winding shaft 2; when the rope body 1 is unloaded, in order to adjust the position of the end of the rope body 1, the winding shaft 2 can be used for carrying out certain winding and unwinding, when the rope body 1 is released, the resistance mechanism does not operate (the resistance mechanism can be one or two resistance plates capable of extruding the rope body 1), when the rope body 1 is wound on the winding shaft 2, the resistance mechanism operates and applies certain resistance to the rope body 1 in the connecting piece 3, so that the rope body 1 between the connecting piece 3 and the winding shaft 2 has certain tensioning force, the winding shaft 2 rotates at the moment, the rope body 1 can be tightly wound on the winding shaft 2, and the condition that the rope body 1 on the winding shaft 2 is loosely wound is avoided as much as possible.
According to the weighing rope mechanism provided by the embodiment of the invention, when the rope body 1 is loaded, the weight of the rope body 1 and the load thereof can be weighed by arranging the weighing module in the connecting piece 3, so that whether the total weight of the rope body 1 and the load thereof exceeds the maximum bearing capacity of the winding shaft 2 is determined; when the rope body 1 is loaded, the rope body 1 has a certain tensioning force, the winding shaft 2 rotates at the moment, and the rope body 1 can be tightly wound on the winding shaft 2; when the rope body 1 is in idle load, the resistance mechanism operates and applies resistance to the rope body 1, at the moment, the winding shaft 2 rotates, the rope body 1 can be tightly wound on the winding shaft 2, and the situation that the rope body 1 is loosely wound on the winding shaft 2 is avoided as much as possible.
In still another embodiment of the present invention, further, the connecting member 3 is rotatably connected to the first pulley 4 and the second pulley 5, and one end of the rope 1 is fixed on the winding shaft 2, and the other end is wound on the first pulley 4 and the second pulley 5. Specifically, the first pulleys 4 and the second pulleys 5 are staggered in the length direction of the winding shaft 2, the position of the second pulleys 5 is higher than that of the first pulleys 4, the rope body 1 on the winding shaft 2 firstly penetrates through the bottoms of the first pulleys 4 and then penetrates through the tops of the second pulleys 5, and finally penetrates out from one side, far away from the first pulleys 4, of the second pulleys 5; so set up, when rope body 1 load, rope body 1 has an ascending extrusion force to first pulley 4, has a decurrent power to second pulley 5, can set up weighing module in second pulley 5 department this moment, so can convert the pressure that second pulley 5 bore through the weighing module when rope body 1 loads to calculate the weight of rope body 1 and its load and weigh (this is prior art, not described in detail).
Still further, the resistance mechanism includes a friction plate 6 slidably coupled within the connector 3. Specifically, the friction plate 6 is positioned at the top of the second pulley 5, and one side of the friction plate 6, which is close to the second pulley 5, is configured as a rough surface, so that the friction force between the friction plate 6 and the rope body 1 is improved; the connecting piece 3 is internally provided with a vertical movable groove, and the friction plate 6 is slidably connected in the movable groove, so that the friction force of the friction plate 6 on the rope body 1 can be controlled by controlling the position of the friction plate 6 in the movable groove (a hydraulic rod can be arranged in the movable groove to control the friction plate 6 to slide).
As an alternative to sliding the driving friction plate 6, it is preferable that both ends of the first pulley 4 are rotatably connected with first connecting blocks 7, and an elastic member is disposed in the connecting member 3, and is used for forcing both the first connecting blocks 7 to move to a side far away from the winding shaft 2, and the first connecting blocks 7 are fixed with the friction plate 6. Specifically, in this embodiment, the first pulley 4 is rotatably connected to two first connecting blocks 7, and the two first connecting blocks 7 are connected to the connecting member 3 through an elastic member; the elastic member may be a guide rod and a spring (not shown) to force the first link 7 to move to a side far from the winding shaft 2 while guiding the movement of the first link 7, and preferably includes an inner rod 8 vertically fixed to the link 3, an extension 9 vertically constructed at the top of the first link 7, one end of the friction plate 6 fixed to the extension 9 (i.e., the first link 7 is fixed to the friction plate 6 through the extension 9), a telescopic groove constructed inside the extension 9, a first spring 10 fixed to an inner wall of the telescopic groove, and a tip of the first spring 10 fixed to a tip of the inner rod 8 to force the first link 7 and the friction plate 6 to move to a side far from the inner rod 8 through the first spring 10. The function of the arrangement is that when the rope body 1 is in no load, the first pulley 4 moves to the bottom end of the stroke (the first pulley 4 has a certain stroke when sliding along the inner rod 8) under the action of the first spring 10, and at the moment, the friction plate 6 also extrudes the rope body 1 on the second pulley 5 under the action of the elastic force of the first spring 10, so that a certain friction force is applied to the rope body 1; when the rope body 1 is loaded, the rope body 1 has an upward force on the first pulley 4, so that the first pulley 4 presses the first spring 10 and moves upwards along the inner rod 8, and further drives the first connecting block 7 and the friction plate 6 to synchronously move upwards along the inner rod 8, so that the friction plate 6 is separated from the rope body 1 on the second pulley 5. So set up for second pulley 5 slides in connecting piece 3 according to the load condition of rope 1 is automatic, and when rope 1 is empty, second pulley 5 is located its stroke bottom, and friction plate 6 is automatic extrudeed rope 1 in order to exert the resistance this moment, and when rope 1 loads, second pulley 5 upwards moves certain distance (according to the load of rope 1 and the elastic coefficient of first spring 10 confirm the travel distance of first pulley 4), and friction plate 6 breaks away from with rope 1 this moment is automatic, and friction plate 6 continuously moves when avoiding rope 1 load as far as possible.
When the rope 1 is in idle load, the friction plate 6 applies resistance to the rope 1, so that the rope 1 is conveniently wound on the winding shaft 2, and at the moment, if the rope 1 on the winding shaft 2 needs to be paid out, a pulling force needs to be applied to the end of the rope 1, so that the rope 1 is obviously inconvenient to pull out from the connecting piece 3 when the winding shaft 2 pays out the rope 1; preferably, an electric push rod 11 is fixed in the connecting piece 3, and the top end of the electric push rod 11 is positioned at the bottom of the first connecting block 7; when the rope body 1 needs to be paid out, the electric push rod 11 is extended to push the first connecting block 7, so that the first connecting block 7 and the friction plate 6 are forced to move upwards, and a forcing means can be added while the friction plate 6 automatically operates, so that different situations can be dealt with. When the rope body 1 needs to be lifted, the winding shaft 2 rotates to drive the rope body 1 to extrude the first pulley 4, at the moment, the first pulley 4 extrudes the first spring 10 through the first connecting block 7 to move, the winding shaft 2 winds part of the rope body 1, but the weight is not lifted, until the extrusion force born by the first spring 10 is the same as the extrusion force born by the first spring 10, the position of the first pulley 4 is not moved, and at the moment, the winding shaft 2 continues to wind and can lift the weight at the end of the rope body 1.
In another embodiment provided by the invention, further, the diameter of the second pulley 5 is larger than that of the first pulley 4, and a part of the second pulley 5 is on the movable stroke of the first pulley 4. Specifically, the first pulley 4 has a certain stroke when sliding along the inner rod 8, when the first pulley 4 is at the top end of the stroke, the weighing rope mechanism reaches the maximum bearing capacity, at this time, the first pulley 4 is close to being jointed with the second pulley 5 (the rope body 1 is positioned between the first pulley 4 and the second pulley 5, the diameter of the rope body is larger and protrudes out of the first pulley or the second pulley, the first pulley 4 and the second pulley 5 are not jointed but simultaneously squeeze the rope body 1), the function of the device is that when the weight borne by the end of the rope body 1 exceeds the maximum bearing capacity of the weighing rope mechanism, the rolling shaft 2 rotates to drive the first pulley 4 to move upwards along the inner rod 8, meanwhile, the first connecting block 7 extrudes the first spring 10, if the first pulley 4 moves to the top end of the stroke, the weight of the end of the rope body 1 is not lifted, so that the weight of the end of the rope body 1 exceeds the maximum bearing capacity of the weighing rope mechanism, at the moment, the first pulley 4 and the second pulley 5 are closely attached and extrude the main body at the same time, so that the first pulley 4 and the second pulley 5 are limited to rotate, the continuous operation of the winding shaft 2 and the rope body 1 is limited, the operation of the weighing rope mechanism is forcedly stopped, overload operation of the weighing rope mechanism is avoided as much as possible, and the safety coefficient of a heavy rope is reduced as much as possible.
It should be noted that, if the diameter of the rope 1 is smaller, when the first pulley 4 moves to the top end of the travel, the outer wall of the first pulley 4 is attached to the outer wall of the second pulley 5, because the diameter of the rope 1 is smaller, and there is a certain moving space between the first pulley 4 and the second pulley 5, the rope 1 will not be extruded in this process, at this time, the rope 1 and the winding shaft 2 still can continue to run, for this purpose, the elastic pieces 71 are fixed on the first connecting block 7, the ends of the elastic pieces 71 are fixed with the pads 72, two elastic pieces 71 may be provided, two elastic pieces 71 are respectively fixed on two sides of the pad 72, and the two elastic pieces 71 are respectively fixed with the two first connecting blocks 7, so that the pad 72 is forced to be located outside the first pulley 4 by the elastic pieces 71 (the pad 72 is not in contact with the first pulley 4, and in the process that the first pulley 4 rotates along with the rope 1, the pad 72 is always located between the first pulley 4 and the second pulley 5), both sides of the pad 72 are configured to be rough surfaces, and both sides of the pad 72 are respectively adapted to the first pulley 4 and the outer wall 1. So set up, when making first pulley 4 remove its stroke top, first pulley 4 is close the laminating with second pulley 5 and extrudees rope 1 and cushion 72 (when cushion 72 received the extrusion, the elastic piece 71 is crooked slightly for cushion 72 both sides are contradicted respectively to rope 1 and second pulley 5), in order to restrict the operation of rope 1 through the extrusion, and then force to stop the operation of rope mechanism.
Still further, the connecting piece 3 is provided with a second connecting block 12, the second pulley 5 is rotatably connected to the second connecting block 12, one end of the second pulley 5 is fixed with a friction wheel 13, and the second connecting block 12 is slidably connected with a friction block 14. Specifically, in this embodiment, the second pulley 5 is rotatably connected to the second connection block 12 on the connection member 3, one end of the second pulley 5 penetrates through the second connection block 12 and the end is fixed with the friction wheel 13, a movable groove is vertically configured on the second connection block 12, the friction block 14 is slidably connected in the movable groove, and the top end of the friction block 14 is configured as an arc rough surface adapted to the friction wheel 13; the effect of this arrangement is that when the first pulley 4 moves to its travel top, the weighing cable mechanism reaches its load limit, and the friction block 14 is controlled to move to the top of the movable groove at this time, so that the friction block 14 brakes the friction wheel 13, and further the rotation of the second pulley 5 is restricted, thereby improving the braking effect on the weighing cable mechanism. The movement of the friction block 14 along the movable groove can be controlled by an electric telescopic rod, and the first connecting block 7 can be fixed by the connecting rod 15, so that when the first pulley 4 and the second connecting block 12 move to the top end of the stroke, the connecting rod 15 drives the friction block 14 to move to the top end of the movable groove, and the friction wheel 13 is braked.
Preferably, a connecting rod 15 is fixed on the first connecting block 7, a connecting groove communicated with the movable groove is formed on the second connecting block 12, the connecting rod 15 is positioned in the connecting groove and at the bottom of the friction block 14, an elastic telescopic rod 16 is fixed in the movable groove, the other end of the elastic telescopic rod 16 is fixed with the friction block 14, and the friction block 14 can be forced to be positioned at the bottom of the movable groove through the elastic telescopic rod 16; the connecting rod 15 is driven to synchronously move in the connecting groove when the first connecting block 7 moves upwards, so that the friction block 14 is forced to stretch the elastic telescopic rod 16 through the connecting rod 15 and move along the movable groove until the first connecting block 7 moves to the top end of the stroke, the friction block 14 is forced to be abutted against the friction wheel 13 by the connecting rod 15, so that the friction wheel 13 and the second pulley 5 are limited, and when the first pulley 4 and the first connecting block 7 are reset, the friction block 14 is reset under the action of the tension of the elastic telescopic rod 16.
Still further, a locking block 17 is slidably connected to the second connecting block 12, a return spring 18 is disposed between the locking block 17 and the second connecting block 12, and a locking groove corresponding to the limiting block is configured on the friction block 14.
