Description
Technical Field
The application relates to the technical field of mechanical equipment, in particular to a rope arrangement device with load.
Background
In the prior art, it is very common to hoist weights by means of hoisting machinery. When the crane lifts the heavy object, the lifting steel wire rope is used for lifting the heavy object. One end of the lifting wire rope passes through the lifting hook and then is fixed at a certain fixed position, the other end of the lifting wire rope is wound on the lifting drum of the crane, and the motor of the lifting mechanism drives the lifting drum to rotate positively and negatively to realize the rope winding and unwinding of the lifting wire rope, so that the lifting hook is lifted and lowered. In the actual running process of the multi-layer winding lifting drum, because the lifting weight is large, the stress of the lifting steel wire rope is large, so that the upper steel wire rope of the lifting drum extrudes the lower steel wire rope (namely, extrudes the rope), even the condition that the upper steel wire rope of the lifting drum directly falls into the lower steel wire rope (namely, sinks the rope) in the process of lifting the weight, no matter the rope extrusion condition or the rope sinking condition, the arrangement of the steel wire rope on the lifting drum becomes messy, the friction of the steel wire rope in the rope collecting and releasing processes is increased, the service life of the steel wire rope is reduced, and the steel wire rope is extruded and deformed, extruded to scattered strands, extruded to bends and the like to directly reach the steel wire rope scrapping condition, so that the potential safety hazard of direct breakage of the steel wire rope in the use process is increased.
Disclosure of Invention
The application aims to provide a load rope arrangement device, which solves the problems that in the prior art, after a heavy object is hoisted, a steel wire rope is easy to squeeze and sink on a hoisting drum, the steel wire rope on the hoisting drum is messy when the steel wire rope is light, and the service life of the steel wire rope is reduced and even potential safety hazards are brought when the steel wire rope is heavy.
In order to achieve the above object, the basic scheme of the present application is as follows:
the utility model provides a take and carry rope arranging device, includes the frame and rotates the rope reel that holds of connection in the frame, rong Shengjuan a coaxial fixedly connected with carousel, carousel circumference is equipped with a plurality of archs, forms the recess between the adjacent arch, is connected with two at least blocking pieces in the frame, all is connected with the elastic component on every blocking piece, and blocking piece homoenergetic is inserted on the recess, and the arch can promote blocking piece withdrawal groove.
Compared with the prior art, the beneficial effects are that:
when the scheme is adopted, the existing mode of directly winding the steel wire rope on the lifting winding drum of the lifting mechanism in an idle load manner is changed into an auxiliary winding mode by using the device, and particularly, the steel wire rope on the rope containing winding drum of the device is gradually discharged and wound on the lifting winding drum of the lifting mechanism; because the device is provided with the blocking blocks, when the rope containing drum rotates, the rotating disc fixedly connected with the rope containing drum must rotate to realize rope arrangement action of the rope containing drum, but when the rotating disc rotates, the plurality of blocking blocks can be continuously inserted into the grooves of the rotating disc under the action of the elastic parts, so that the rotating disc can not rotate freely all the time; in order to enable the turntable to rotate, the blocking blocks contacted with the turntable are gradually pushed by the bulges, the blocking blocks gradually withdraw from the grooves between the adjacent bulges by overcoming the elastic potential energy of the elastic parts, and the turntable can rotate only by the fact that the turntable can be slowly rotated by enough external force in the process, so that the rope containing drum fixedly connected with the turntable can rotate by enough tangential force, and is connected with the lifting drum through the steel wire rope, and the lifting drum is driven to rotate by the lifting mechanism to further pull the lifting drum to rotate by the wire rope to generate line load. In the process, the winding of the steel wire rope on the lifting reel is realized under the condition of the load, the winding process of the lifting reel simulates the process of lifting the heavy object once, so that the upper layer steel wire rope cannot be continuously extruded into the very compact lower layer steel wire rope even if the subsequent lifting mechanism is used for lifting the heavy object, the situation that the upper layer steel wire rope is extruded into or sunk into the lower layer steel wire rope of the lifting reel is avoided, and the problems that the service life of the steel wire rope is shortened and potential safety hazards are caused due to the fact that the steel wire rope on the lifting reel is messy and even the upper and lower layers of steel wire ropes are worn and extruded mutually due to the rope extruding situation and the rope sinking situation are solved.
In addition, adopt this device to rise the reel and carry out the in-process of arranging the rope, because of the quantity of blocking piece has a plurality ofly, in the in-service use, when guaranteeing that partial blocking piece is released completely from the recess, still there is the condition that at least one blocking piece inserted the recess, and then guarantees that the carousel always needs just can rotate under the exogenic action, and then ensures that the whole in-process wire rope of playing of this device is in the condition that has the line load all the time, is favorable to guaranteeing to rise the compactibility of reel wiring.
In addition, because the blocking blocks are multiple, even if one blocking block fails, other blocking blocks still continue to block the rotation of the rope containing drum, so that the rope containing drum is ensured to keep continuously carrying and arranging ropes.
Further, the frame includes support and two staple bolts that set up relatively, and two staple bolts pass through the double-end screw rod fixed connection that is equipped with, and double-end screw rod rotates to be connected on the support, and the carousel is located the enclosing space of two staple bolts, and elastic component one end supports tightly on the staple bolt, and the other end supports tightly on the block.
