Description

A kind of mechanical device of lifting means cable wire guiding

Technical field

The utility model relates to the cable wire guide piece, relates in particular to a kind of mechanical device of lifting means cable wire guiding.

Background technology

In lifting means, the lifting means that lifts by cable wire is a lot, but nearly all has a problem: cable wire slides down when winding or unwrapping wire or shakes, and causes raised position inaccurate, and motor fluctuation is big.For the big influence of the not high lifting means of accuracy requirement, but just big for the crystal growth influence in the picture monocrystal growing furnace.So flexible axle slides down and just shakes and is even more important in the control monocrystal growing furnace.

Summary of the invention

The purpose of this utility model is in order to overcome sliding down and shaking of cable wire in the lifting means, to lift the precision of motion, a kind of mechanical device of lifting means cable wire guiding being provided.

The mechanical device of lifting means cable wire guiding comprises cover in rolling wheel support, roller shaft, the roller, unsteady roller, gear shaft plate, pressure spring, bearing, marks closely screw and O type circle; Two blind holes are arranged on the leg of rolling wheel support, pressure spring is housed respectively in blind hole, roller shaft is contained in the axial trough on the leg of rolling wheel support, contact with pressure spring, the gear shaft plate blocks roller shaft by marking closely screw retention on the leg of rolling wheel support, and pair of bearings is equipped with at the two ends of roller shaft, be sleeved in the roller on the bearing, unsteady roller is contained in the roller and puts.

Described rolling wheel support is provided with seal groove, is provided with O type circle in the seal groove.

The utility model simplicity of design realizes easily, and motion steadily.Apply in the lifting means, strengthen to lift contacting of cable wire and lifting means roll, make cable wire, avoid sliding down or shaking twining or not becoming flexible during unwrapping wire.

Description of drawings

Fig. 1 is the structural representation of cable wire guide piece;

Among the figure: cover 3, float roller 4, gear shaft plate 5, pressure spring 6, bearing 7 in the rolling wheel support 1, roller shaft 2, roller, mark closely screw 8, O type circle 9.

The specific embodiment

As shown in Figure 1, the mechanical device of lifting means cable wire guiding comprises cover 3 in rolling wheel support 1, roller shaft 2, the roller, unsteady roller 4, gear shaft plate 5, pressure spring 6, bearing 7, marks closely screw 8 and O type circle 9; Two blind holes are arranged on the leg of rolling wheel support 1, pressure spring 6 is housed respectively in blind hole, roller shaft 2 is contained in the axial trough on the leg of rolling wheel support 1, contact with pressure spring 6, gear shaft plate 5 blocks roller shaft 2 by on the leg of marking closely screw 8 and being fixed on rolling wheel support 1, and pair of bearings 7 is equipped with at the two ends of roller shaft 2, cover 3 is contained on the bearing 7 in the roller, and the roller 4 that floats is contained in the roller and overlaps on 3.

Described rolling wheel support 1 is provided with seal groove, is provided with O type circle 9 in the seal groove.

Rolling wheel support 1 is the pallet of a band leg, and leg is interior sky, is made up of blind hole and axial trough, will put two pressure springs 6 in the blind hole the inside, and purpose is the antagonistic force by pressure spring, makes roller shaft 2 and unsteady roller 4 reach stress balance by floating.Roller shaft is to be placed in the axial trough of rolling wheel support leg, and two ends just contact with pressure spring in two legs, on two legs of rolling wheel support 1 two screws are arranged respectively, are used for by marking closely screw gear shaft plate 5 being fixed on the leg of rolling wheel support.For the roller 4 that floats is not interfered when rotated, enough spaces are arranged on every side, at the center of rolling wheel support 1, dig out a hole groove that caves between two legs.

Roller shaft 2 be two end mills flat axle with the level, the flat horizontal surface at two ends just is placed in the axial trough of rolling wheel support 1 leg, and is relative with the axial trough side, the step of roller shaft just is stuck in the middle of two legs of rolling wheel support 1.Roller shaft 2 is centers of unsteady roller 4 rotations, is connected with cover 3 in the roller by the pair of bearings on the axle 7.

Cover 3 is sleeves of step in the band in the roller, interior dress pair of bearings 7, and the outer roller 4 that floats of adorning, it is a consumable accessory, fatiguability is impaired in the rotation that does not stop, and in the use spare part will be arranged.The purpose of cover 3 is exactly to make revolving part minimizing in the process of rotation increase the service life of the roller 4 that floats to the wearing and tearing of the roller 4 that floats in the dress roller.

The roller 4 that floats is cylinders empty in, the tyre step, length is slightly less than the interior crotch of rolling wheel support two legs, just be installed in the centre of two legs, on the external cylindrical surface of roller 4 that floats wire casing arranged, the width of wire casing and the degree of depth are by the employed cable wire model decision of lifting means.When make floating roller 4, material will select high-abrasive material, because it will contact with the cable wire of up-and-down movement, and does uncertain motion.

Gear shaft plate 5 is rectangular flat plate that two holes are arranged, and by marking closely on the leg that screw is fixed on rolling wheel support 1 of penetrating, is used for blocking roller shaft 2 and is not ejected axial troughs by pressure spring 6.

Pressure spring 6 is contained in the blind hole of rolling wheel support leg, and the bounce by its pressurized produces promotes roller shaft 2, and drives the roller 4 that floats and shift to the cable wire of lifting means, and gives pressure.

O type circle 9 is in order to vacuum-packed, is contained in the seal groove on the rolling wheel support.If this device is used on the general lifting means, there is not seal request, just can save need not.

The working process of this device: this device is installed on a side of lifting means roll rope stretching, sagging cable wire place one side when just lifting object, and make the roller shaft 2 of this device parallel with the lifting means roll, and on a horizontal surface.Regulate the installation site, make the sagging cable wire on the just corresponding firmly lifting means roll of wire casing on the unsteady roller 4, the roller 4 that at this moment floats just is clipped in sagging cable wire in the cableway of both compositions with the lifting means roll.When lifting means is carried heavily, cable wire is carrying weight and is lifting, cable wire is subjected to stretching and tightens under the effect of weight, generally can not slide down, but shake easily in the moment that starts and stop, at this moment the shake of cable wire passes to the roller 4 that floats, the shake that the roller 4 that floats will be subjected to when rotating along with the up-and-down movement of cable wire passes to pressure spring 6 by roller shaft 2, pressure spring 6 utilizes the rebounding characteristic of oneself that shake is rebounded, promote roller shaft 2, shift to the lifting means roll, drive the roller 4 extruding cable wires that float, weaken the shake of cable wire.When lifting means is unloaded, cable wire is because of being subjected to pulling force little and lax, slide down easily and upspring, at this moment the roller 4 that floats just is subjected to a radial thrust of cable wire, by overlap 3 in the roller, bearing 7 passes to roller shaft 2, roller shaft 2 is exerted pressure to pressure spring 6, pressure spring 6 bounce-backs, again the power that is subjected to is passed to the roller 4 that floats by roller shaft 2, make it to depress the cable wire of upspringing, force the cable wire return.So just realized unsteady dragline, constantly Kong Zhi purpose.
