Abstract

The invention discloses a lifting rope switch control device of lifting equipment. The lifting rope switch control device comprises a box body base, a rope withdrawing spring, a main shaft, a pressing wheel, a limiting hinge pin, an encoder, a rope withdrawing wheel and a rope, wherein one end of the rope withdrawing spring is fixed on the box body base; the other end of the rope withdrawing spring is fixedly connected with the main shaft; the rope withdrawing wheel is fixed on the main shaft; certain torsion can be generated when the rope withdrawing spring is pre-tightened, and then the rope can be wound and tightened on the rope withdrawing wheel; the rope penetrates through a guide wheel and the pressing wheel; the rope can be tightened by adjusting the pressing wheel. The rope can be pulled to move downwards for a certain distance, the guide wheel is rubbed by the rope to enable the guide wheel to move in one direction, the encoder is driven by a coupling to rotate correspondingly, then a corresponding program can be set by the encoder to transmit a signal, and the lifting equipment can move in a related direction; when the rope is dragged in an opposite direction to move for a certain distance, the main shaft of the encoder is rotated in the opposite direction, and then the lifting equipment can move in the opposite direction; when moving up and down, the lifting equipment can be stopped by pulling the rope in any direction.

Description

A kind of lifting rope switch controlling device of jacking equipment

Technical field

The present invention relates to a kind of operating control device in jacking equipment field, high-altitude.

Background technology

Current jacking equipment control mode is limited, wherein mainly uses manned manual mode, under MANUAL CONTROL mode, is risen by the guidance panel realization on operating personnel's control equipment, decline, is started or stoped；Another kind of common control mode is remote control mode, under remote control mode, operating personnel can by the rising of remote controller control device, decline, start or stop, conveying articles reach specify workbench；Owing under manned manual mode, operating personnel itself take the space of a part of jacking equipment, greatly reduce device interior space, cause being inconvenient to transport goods and materials, remote control mode is relatively costly, simultaneously because by jacking equipment the highest operation height uncertain, the transmitting of remote signal and reception can be made to be affected, remote controller control function will decline, so can not meet the requirement of jacking equipment performance, the requirement of client can not be met.

For solving the problems referred to above, a kind of lifting rope switch controlling device of the jacking equipment of design, this kind of device integrally uses mechanical control method, it not be used in jacking equipment itself and supply unit is installed, also the mode run with Digiplex control jacking equipment is abandoned, the reliability making device increases, and safety coefficient increases, additionally it is possible to cost-effective.

Content of the invention

For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:

There is provided the lifting rope switch controlling device of a kind of jacking equipment, it has box base, rope closing spring, main shaft, contact roller, spacing bearing pin, encoder, rope closing wheel and rope；Pulling rope makes it move downward a segment distance, and rope friction wheel makes guide wheel rotate to a direction, drives encoder to do corresponding rotation by shaft coupling, and encoder arranges corresponding program and provides signal, and this jacking equipment moves to related direction；When reverse pull rope make its move a segment distance after, encoder main shaft opposite direction rotates, and this jacking equipment moves round about；Pull this jacking equipment of rope to stop during this jacking equipment moves up and down to any direction.

A modification of the present invention is, described device is arranged on outside jacking equipment itself.

A modification of the present invention is, box base is respectively mounted and is fixed at cat ladder upper end lower end two；Told rope draws rope closing wheel up and down along the direction of cat ladder, reaches balance by the pretension elastic force of rope closing spring itself, puts rope for rope closing.

A modification of the present invention is, rope closing spring one end is fixed on the main shaft of box base, and the other end is spacing by spacing bearing pin.

A modification of the present invention is, described encoder is fixed on box base, and rope passes through guide wheel and contact roller, and two ends are fixed on rope closing wheel.

According to this mechanism, can save jacking equipment itself space, reduce cost, convenient succinct, improve the reliability of jacking equipment；This kind of device integrally uses mechanical control method, not be used in jacking equipment itself and installs supply unit, also abandons the mode run with Digiplex control jacking equipment, makes the reliability of device increase, and safety coefficient increases, additionally it is possible to cost-effective.

Detailed description of the invention

Hereinafter, will be described in detail with reference to the accompanying drawings the preferred version of the present invention, in the specification and illustrated in the drawings, the element with identical function and structure is presented with like reference characters, and omits the repeat specification to these structures.

Fig. 1 is this device overall structure schematic diagram, and it mainly includes box base 1, spacing bearing pin 2, main shaft 3, contact roller 10, guide wheel 12 and rope closing spring 16, and this kind of control running gear also includes encoder 6, rope closing wheel 4, rope 5.

Shown in Fig. 2 is box base 1 and the fixing schematic diagram of rope closing spring 16, and the concrete shape of the box base 1 shown in figure can be optional, preferably square box；Square box is fixed with cat ladder 13, and fixed form can be optional, according to depending on actual conditions；One end of rope closing spring 16 is fixed by keyway and the main shaft 3 of main shaft 3, and main shaft 3 is fixed on box base 1 by bearing block 15；Rope 5 shown in figure can be optional, preferably ductility, elastic little rope, and the lower end of rope 5 is fixed on rope closing wheel 4, rope 5 can be made to be wrapped on rope closing wheel 4 by rotating main shaft 3, make rope closing spring 16 pretension；The other end of rope closing spring 16 is spacing by spacing bearing pin 2, reaches the purpose of fixing rope closing spring 16 end；The purpose of rope closing and tension just can be realized when rope is dynamic about 5 after rope closing spring 16 pretension produces corresponding elastic force.
