Description

Technical Field

[0001] This utility model relates to the field of rope arrangement technology, specifically to a rope arrangement auxiliary device for steel wire rope on a hoisting machinery drum. Background Technology

[0002] During lifting operations, the wire rope is repeatedly wound and released on the drum as the load is lifted and lowered. Ideally, the wire rope is arranged neatly and tightly on the drum, with each turn of the wire rope closely fitted and smoothly transitioning between layers. However, in actual working conditions, due to the torsional force and rigidity of the wire rope, it tends to twist under tension and free suspension, leading to rope disorder. This disorder causes the wire rope to jump out of its original groove, squeezing and overlapping each other, forming a "tangled rope" phenomenon. The "Auxiliary Lifting Mechanism Rope Guiding Wheel Device" disclosed in patent publication number CN213595757U includes an auxiliary lifting mechanism and a rope guiding wheel device installed on the auxiliary lifting mechanism. The rope guiding wheel device includes two brackets, which are symmetrically fixed to the bottom surface of the outer frame. The patent describes a system where a rope-pressing rod and a rotating shaft are supported between two brackets. The rope-pressing rod is parallel to the rotating shaft, and a nylon wheel is fitted onto the rotating shaft. In this patent, the nylon wheel is used to guide the wire rope. However, in this patent, the nylon wheel is loosely fitted onto the rotating shaft, and the fit between the nylon wheel and the shaft is usually a clearance fit or a simple sliding fit. This gives the nylon wheel two degrees of freedom on the shaft: one is movement along the axial direction of the shaft (which is required for rope laying); the other is rotation around the axis of the shaft (which needs to be avoided). The rotation of the nylon wheel will cause the relative positional relationship with the wire rope to become disordered, making it impossible to achieve precise and stable guidance. Instead, it will generate additional sliding friction with the wire rope, which will not only accelerate the uneven wear of the nylon wheel itself, but may also aggravate the wear of the wire rope, affecting the overall performance and reliability of the rope laying aid. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a simple, reasonably designed, and easy-to-use wire rope arranging auxiliary device for lifting machinery drums.

The insert block is fixedly disposed on the front side of the connecting block and is inserted into the sliding block; The positioning components are two in number, respectively located on the left and right sides of the connecting block; The above technical solution involves sliding the sliding block through the fixed block and installing a guide ring on the rear side of the sliding block. The wire rope passes through the guide ring, and the sliding block moves within the fixed block, thereby moving the guide ring to adjust the guiding position of the wire rope.

[0005] As a further improvement of this utility model, the positioning component includes: The support frame is an "L" shaped structure. The horizontal end of the support frame is fixedly mounted on the outer wall of the sliding block. The longitudinal end of the support frame is screwed through a bearing and a support shaft is fixedly mounted on the inner end of the support shaft. The movable frame is configured with an "L" shape. The longitudinal end of the movable frame is slidably disposed within the transverse end of the support frame, and the lead screw is threadedly connected and inserted into the longitudinal end of the movable frame.

The rotating handle is fixedly installed at the outer end of the support shaft. A locking pin is inserted through the rotating handle, and a screw is fixedly installed at the inner end of the locking pin. The screw is threaded through the longitudinal end of the support frame. Through the above technical solution design, the rotating handle is manually rotated to rotate the lead screw, thereby driving the moving frame with a thread, causing the positioning block to move and insert into the connecting block. By tightening the screw at the end of the locking column, it is pressed against the support frame, thereby fixing the position of the support shaft and the lead screw, realizing the positioning of the moving frame and the connecting block.

[0006] As a further improvement of this utility model, a guide block is provided on the front side of the sliding block, and the guide block is in contact with the front side of the fixed block. The above technical solution guides the movement of the sliding block.

[0007] As a further improvement of this utility model, guide rods are fixedly and symmetrically arranged on both the upper and lower sides of the sliding block, and the guide rods slide through the guide grooves opened in the fixed block.

[0010] The working principle of this utility model is as follows: A sliding block is slidably inserted into a fixed block; a guide ring is installed on the rear side of the sliding block. The rotating handle is manually rotated to rotate the lead screw, thereby driving the moving frame through the thread. This causes the positioning block to move and insert into the connecting block. By tightening the locking screw at the end of the locking column, it is pressed against the support frame, thus fixing the position of the support shaft and the lead screw, positioning the moving frame, and positioning the connecting block, thereby strengthening the connection between the guide ring and the sliding block. A steel wire rope is threaded through the guide ring. The sliding block moves within the fixed block, thereby driving the guide ring to move together to adjust the guiding position of the steel wire rope. A fixed guide post and a movable guide post are added to the lower side of the guide ring. The steel wire rope is threaded between the movable guide post and the fixed guide post. The cylinder is activated to drive the movable guide post, causing it to cooperate with the fixed guide post to guide the steel wire rope on the lower side of the guide ring.
