Abstract
The utility model discloses a wire rope locking rope protector, including adjusting screw, switch support, limit switch, compression spring, fixing base, link plate and the fixed wedge cover of wire rope, limit switch connects on the lateral wall of fixing base, adjusting screw cup joints switch support, compression spring and fixing base in proper order, the one end that adjusting screw is located the fixing base below is equipped with the connecting piece, the connecting piece is through selling a round pin hub connection link plate, the link plate is through selling two fixed wedge covers of connecting wire rope of axle. Compared with the prior art, the utility model the advantage lie in: the steel wire rope looseness caused by continuous descending of the crane in a stress-free state is avoided.
Description
Technical Field
The utility model relates to a hoist wire rope connection protection technical field specifically indicates a wire rope prevents that rope slackens protector.
Background
The automatic crane adopts unmanned operation when carrying the work piece, and after the hoist handling work piece descends to the right place, there is the risk of continuing to descend in the hoist, if the hoist continues to descend easily to cause wire rope not hard up, leads to wire rope to deviate from the pulley easily on the one hand, and on the other hand the hoist is easy to break wire rope when rising again.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a hoist and continuously descend and lead to the not hard up locking rope protector of wire rope when avoiding wire rope not have stress state.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a wire rope locking rope protector, includes adjusting screw, switch bracket, limit switch, compression spring, fixing base, link plate and the fixed wedge cover of wire rope, limit switch connects on the lateral wall of fixing base, adjusting screw cup joints switch bracket, compression spring and fixing base in proper order, the one end that adjusting screw is located the fixing base below is equipped with the connecting piece, the connecting piece is through selling the first link plate of round pin axle, the link plate is through selling the fixed wedge cover of two connection wire ropes of round pin axle.
As an improvement, one end of the compression spring is connected with the fixed seat, and the other end of the compression spring is connected with the switch bracket.
As an improvement, a limit deflector rod matched with the switch bracket is arranged on the limit switch.
Compared with the prior art, the utility model the advantage lie in: the hoisting state of the crane is as follows: the bottom of the adjusting screw is hoisted through a connecting piece and is sequentially sleeved with the switch bracket, the compression spring and the fixing seat, and the adjusting screw can compress the spring to drive the switch bracket to move downwards and press the limiting deflector rod downwards, so that the limiting switch is always in a closed state; releasing the heavy object, wherein the steel wire rope is in an unstressed state: the compression spring resets to drive the switch bracket to move upwards, the limit deflector rod resets, and the limit switch is electrically contacted to break the descending control loop, so that the crane stops descending, the steel wire rope is prevented from falling off, and accidents are prevented from being relieved.
Drawings
Fig. 1 is the utility model discloses a wire rope locking rope protector structural schematic.
Fig. 2 is the utility model relates to a wire rope anti-loosening protector looks sideways at the structural schematic diagram.
As shown in the figure: 1. adjusting screw, 2, switch support, 3, limit switch, 4, compression spring, 5, fixing base, 6, link plate, 7, wire rope fixed wedge cover, 8, connecting piece, 9, round pin axle one, 10, round pin axle two, 11, spacing driving lever.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1-2, the wire rope anti-loosening protector comprises an adjusting screw 1, a switch bracket 2, a limit switch 3, a compression spring 4, a fixing seat 5, a hanging plate 6 and a wire rope fixing wedge sleeve 7, wherein the limit switch 3 is connected to the outer side wall of the fixing seat 5, the adjusting screw 1 is sequentially sleeved with the switch bracket 2, the compression spring 4 and the fixing seat 5, a connecting piece 8 is arranged at one end of the adjusting screw 1 below the fixing seat 5, the connecting piece 8 is connected with the hanging plate 6 through a first pin shaft 9, the hanging plate 6 is connected with the wire rope fixing wedge sleeve 7 through a second pin shaft 10, and the wire rope fixing wedge sleeve 7 is used for connecting a wire rope.
The fixing base 5 is connected to 4 one ends of compression spring, and other end connect switch support 2 guarantees that compression spring carries out good reseing, limit switch 3 is last to be equipped with the spacing driving lever 11 of cooperation switch support 2, cooperation switch support control limit switch's closure and electric shock disconnection decline control circuit.
The utility model discloses when concrete implementation, wire rope connects on wire rope fixes wedge cover 7, hangs heavily when the hoist, and wire rope passes through 7 pulling adjusting screw 1 of wire rope fixed wedge cover, compresses compression spring 4, and switch support 3 moves down along with adjusting screw 1, pushes down limit driving lever 11, and limit switch 3 is in the closure state always, and the hoist plays to rise and descends and is in normal condition.
When the hoisted heavy object descends to the proper position, the pressure spring 4 resets to drive the adjusting screw rod 1 and the switch bracket 2 to move upwards, the limiting deflector rod 11 moves upwards, when the lifting hook continuously falls downwards, the steel wire rope is completely free of stress, the pressure spring 4 is in a complete release state, the limiting switch 3 is electrically contacted and disconnected, a descending control loop is disconnected, the crane stops descending, and accidents are prevented.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
