Abstract
The invention relates to a rope outlet structure of gantry crane. The rope outlet structure comprises a cylindrical shell which is connected with a machine room top and is arranged inclinedly, and a front rotating base and a back rotating base positioned at the front and back end of the cylindrical shell; the front rotating base and the back rotating base are connected to double sides of a cover casing movably by a rotation mechanism, and the top of the cover casing is provided with an outlet sleeve, and the exit of the outlet sleeve is enclosed by a seal element, and many carrying rollers are also arranged in the outlet sleeve. The invention has the advantages of simple structure and smaller occupation area, and rain leakage problem at the top of the machine room can be effectively solved by arranging the cylindrical shell and sealing the housing. The wire rope may slip when the rope is discharged or received, thereby the seal rubber leather which contacts with the wire rope follows the movement of the supporting rollers arranged in # shape, and the frictional force of the wire rope is minimized, and the wearing degree of the wire rope is reduced, and the wire rope service life is prolonged, and the occupation space is small, so the rope outlet structure is good for the arrangement of the wire rope outlet at the top of the machine room.
Description
Technical field
The present invention relates to weight-lifting equipment, especially a kind of rope stretching cover structure for span winch.
Background technology
In the prior art, the steel rope of span winch lays out from reel, passes the machine room top and arrives fixed pulley, and rope outlet is the assurance of the smooth rope stretching of span winch as the rope stretching passage of steel rope on the machine room top.The steel rope outlet of adopting at present has two kinds of structural shapes:
One, rubber presser type: this structure adopts steel pipe to surround the machine room mouth that acts during a vacancy, and the steel plate structure plays support, and rubber plate is fixed on the support upper end and protects steel rope to guarantee rope stretching.This structure is simple relatively, makes simple installation, but has following several point defects: 1. this rope outlet need be at machine room top opening square hole, and bore size is bigger, and this method is unfavorable for the more stable and stronger of computer room structure; 2. steel rope with speed and the rubber plate friction of 20 ~ 60m/min, causes rubber plate consumption big mostly; 3. because rubber pressing plate blowing-by adds the wearing and tearing of rubber plate, obviously use this rope outlet the phenomenon that leaks can occur, cause rainwater to enter in the machine house easily.
Two, big ringlet rotating disc type: shown in the structure of the patent No. 201020528249.7, this structure is made up of the muzzle that goes out that arc groove, the roundel of the straight-line groove of big bear and great circle disk cover covers, when reel was put rope or received rope, steel rope is sway in straight-line groove just.The deep-slotted chip breaker drive great circle disk cover that moves through of steel rope rotates around center shaft, drives the roundlet disk cover around self center rotation by going out muzzle simultaneously, rotates with the big disk center shaft with the great circle disk cover again, guarantees that steel rope passes through smoothly.This structural shape can effectively overcome steel rope and cause the problem that leaks by machine room top, but complex structure, and area occupied is big, difficulty in arrangement.
Summary of the invention
The applicant is at above-mentioned existing issue, carried out research and improved, and a kind of simple in structure, rope stretching cover structure that is used for span winch that area occupied is little is provided, have rainproof effective, the advantage that durability is good.
The technical solution adopted in the present invention is as follows:
A kind of rope stretching cover structure for span winch, comprise the cylindrical shell that is connected and is in tilted layout with the machine room top, be positioned at the preceding swivel base of rear and front end device and the back swivel base of cylindrical shell, preceding swivel base and back swivel base flexibly connect by the both sides of rotating mechanism and case, the top that is positioned at case sets out muzzle, the exit that goes out muzzle is sealed by packing element, is positioned at muzzle inside a plurality of carrying rollers also are set.
Its further technical scheme is:
Rotating mechanism comprises the connecting strap affixed with the case both sides, has mounting hole in the connecting strap, installs turning set in mounting hole, and bolt-through is installed described turning set, preceding swivel base or back swivel base, and by nut and spacers;
Be positioned at described case bilateral symmetry connect back plate, the both sides and the described back plate (6) that go out muzzle fit tightly, and are connected with case by bearing pin;
Described packing element is arranged in length and breadth by two, and the rubber skin that forms " ten " font is formed, the two ends symmetry of described rubber skin has mounting hole, and by pressing plate and fastener and to go out muzzle affixed, has the centre hole that can run through for steel rope in the center of two rubber skins;
Described center-hole diameter greater than wirerope diameter to 2mm～4mm;
Described carrying roller is 4, adopts the wear resistant nylon material to make, and is connected with the outlet cover by fastener, and described carrying roller is symmetrically arranged in out muzzle inside in twos, and crisscross formation " well " font;
Go out the internal diameter of muzzle greater than case top external diameter 4mm～8mm;
It is trapezoidal that the opening of case increases formation from top to bottom step by step;
What go out muzzle is shaped as length and the identical cuboid of width.
Beneficial effect of the present invention is as follows:
Structure order of the present invention, area occupied are less, can effectively solve machine room top roof leaking problem by what arrange cylindrical shell and seal casing.Steel rope produces slippage when putting rope or receiving rope, make the caulking gum skin that contacts with steel rope servo-actuated with the carrying roller of " well " font arrangement, reduce the friction force of steel rope, thereby reduce the steel rope abrasion degree, prolong steel rope and use service life, it is little to take up room, and is conducive to the layout of machine room top steel rope outlet.
