Summary of the invention
The objective of the invention is to lift the precision of motion in order to overcome sliding down and shaking of cable wire in the lifting means, a kind of mechanical device of hoister steel cable guiding is provided.
The mechanical device of hoister steel cable guiding comprises rolling wheel support, roller shaft, roller inner sleeve, float 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 is fixed on the leg of rolling wheel support by marking closely screw, blocks roller shaft, 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.
Simplicity of design of the present invention realizes easily, and motion steadily.Apply in the lifting means, strengthen to lift contacting of cable wire and lifting means roll, make cable wire twining or not becoming flexible during unwrapping wire, avoid sliding down or shaking.
Description of drawings
Fig. 1 is the structural representation of steel cable guide device;
Among the figure: rolling wheel support 1, roller shaft 2, roller inner sleeve 3, float roller 4, gear shaft plate 5, pressure spring 6, bearing 7, mark closely screw 8, O type circle 9.
The specific embodiment
As shown in Figure 1, the mechanical device of hoister steel cable guiding comprises rolling wheel support 1, roller shaft 2, roller inner sleeve 3, float 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 is fixed on the leg of rolling wheel support 1 by marking closely screw 8, blocks roller shaft 2, and pair of bearings 7 is equipped with at the two ends of roller shaft 2, roller inner sleeve 3 is contained on the bearing 7, and the roller 4 that floats is contained on the roller inner sleeve 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 one, and leg is interior sky with the pallet of leg, is comprised 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 by floating to reach stress balance.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 inner sleeve 3 is sleeves of step in the band, in-built pair of bearings 7, and exterior unsteady roller 4, it is a consumable accessory, fatiguability is impaired in ceaselessly rotating, and in the use spare part will be arranged.The purpose of dress roller inner sleeve 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.
The roller 4 that floats is empty, outer cylinders with the level in, length is slightly less than the interior crotch of rolling wheel support two legs, just be installed in the centre of two legs, at the external cylindrical surface of the roller 4 that floats wire casing arranged, the width of wire casing and the degree of depth are determined by the employed cable wire model 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.
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 namely 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 wire casing corresponding sagging cable wire of living on the lifting means roll just on the roller 4 that floats, at this moment float roller 4 and lifting means roll just are clipped in sagging cable wire in the cableway that both form.When lifting means is carried heavily, cable wire is carrying weight and is lifting, cable wire is subject 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 subject 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, pushing rolling wheels axle 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 being subjected to pulling force little and lax, slide down easily and upspring, at this moment the roller 4 that floats just is subject to a radial thrust of cable wire, passes to roller shaft 2 by roller inner sleeve 3, bearing 7, and roller shaft 2 is exerted pressure to pressure spring 6, pressure spring 6 bounce-backs, again the power that is subject 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 the purpose of control.
