Description
Technical field
The present invention relates to a kind of jacking system, have at least one telescopic pipe or telescoping cylinder, comprise first band of annular and second band of annular, wherein has device, be used for the first band helix quadrature transverse is provided with around the axis and second band is provided with and is used for first band transferred in the position of piling up that retracts and with second band and transfers in the spiral position that retracts around self rolling, the pitch of the laps of second band laterally is parallel to the axis.The present invention relates to the application of this jacking system in addition.
Background technology
The telescopic pipe of the above-mentioned type or telescoping cylinder are by US 4,875, and 660 A or EP 0 326 910 B1 have disclosed and sold by the PACO SPIRALIFT INC company of Quebec, CAN with title " SpiraLift ".The telescopic pipe of this pure machinery is that it has minimum system height by given stroke with the advantage that the retractor device of traditional pneumatic or hydraulic pressure is compared thus.In this Spirallift lifters, constant on this external total kilometrage of lifting power and current draw.In addition, this lifters is almost non-maintaining and can utilize adapter to move with hand when urgent manually operation.
Summary of the invention
Therefore the objective of the invention is to, improve the serviceability of this jacking system.
This purpose is achieved according to the present invention in by jacking system as described in the preamble thus a kind of, and promptly jacking system has prevent the device that falls when telescopic pipe or telescoping cylinder are malfunctioning.
The present invention is based on this understanding, promptly in the jacking system of working under using this telescopic pipe or telescoping cylinder situation, jacking system can for example surpass under the peak load situation that allows because telescopic pipe or telescoping cylinder technology are fallen when malfunctioning.For reaching maximum serviceability, have and when telescopic pipe or telescoping cylinder are malfunctioning, prevent the foundation of falling device of the present invention.
A kind of formation of the present invention is, prevents that the device that falls has tooth bar and retaining pawl, and retaining pawl latchingly embeds in the tooth bar under the situation of the vertical speed of predesignating that surpasses jacking system.
First kind of selection scheme is in this contact, prevent that the device that falls has tooth bar and waveform section bar rail, the two is fixed on the fixed part of jacking system, and prevent that the device that falls has the retaining pawl that has roller on the part of the energy perpendicular movement that can be rotated to support on jacking system, wherein, have and roller is pressed to the device of section bar rail and retaining pawl constitute and be used to embed in the tooth bar.
When normal operation, roller is close on the section bar rail all the time, guarantees that thus retaining pawl does not embed in the tooth bar.Surpassing the vertical speed that can predesignate, for example under the situation of specified rising or falling speed, roller lifts with retaining pawl from the section bar rail and embeds in the tooth bar.Roller can be changed by the formation of section bar rail and the thrust of roller from the speed that the section bar rail lifts.
Second kind of selection scheme is, prevent that the device that falls has tooth bar and waveform section bar rail, the two is fixed on the part of energy perpendicular movement of jacking system, and prevent that the device that falls has the retaining pawl that has roller that can be rotated to support on the jacking system fixed part, wherein, have and roller is pressed to the device of section bar rail and retaining pawl constitute and be used to embed in the tooth bar.
This scheme is opposite with first kind of solution on kinematics.
In framework of the present invention, the device of roller being pressed to the section bar rail constitutes counterweight.
Determine to act on the thrust of roller and can change by the quality of counterweight and the lever of counterweight by changing these parameters.
The device of roller being pressed to the section bar rail can constitute spring equally.
Fastening what have advantage in this pass is that the spring force of spring can be adjusted.
Can pre-determine the thrust of roller and therefore can pre-determine the triggering speed that prevents the device that falls by adjusting spring force then.
In framework of the present invention, in auto-industry, install especially for traveling gear according to jacking system of the present invention.
In traveling gear is installed (being also referred to as " assembling on vehicle body and chassis "), by the lifting work rest with drive disk assembly and traveling gear part bonding to vehicle body.Many installations and the turn of the screw process after engaging from below carry out, no matter manually still be automatic.Lifters and installation process (the turn of the screw, clamping etc.) need the space of work rest below.The required area of jacking system is more little, can be big more for the area of installing and the turn of the screw instrument passes through.Thus, be specially adapted to this application according to jacking system of the present invention.
Description of drawings
By accompanying drawing embodiments of the invention are described below.Wherein:
Fig. 1 a and 1b illustrate according to the lateral plan of jacking system of the present invention on immigration and outflow location;
Fig. 1 c illustrates according to jacking system of the present invention lateral plan with respect to 90 ° of Fig. 1 a and 1b deflections on outflow location;
Fig. 2 a, 2b and 2c illustrate and prevent the detail drawing of device on different non-stop positions that fall;
Fig. 3 illustrates and prevents the detail drawing of device on stop position that fall.
The specific embodiment
As from seeing Fig. 1 a-1c, has basic framework 2 according to jacking system 1 of the present invention.Have device 3 in this basic framework, be used for the first band helix quadrature transverse being provided with around the axis and second band being rolled setting around self, the pitch of the laps of second band laterally is parallel to the axis; And be used for first band being transferred in the position of piling up that retracts and second band being transferred in the spiral position that retracts.
The jacking system 1 of two sections formations has two devices that prevent to fall when jacking system is malfunctioning in present case.They comprise a vertical Fu tooth bar 4 separately, have the same vertical Fu section bar rail 5 of waveform section and be fixed on the fixed part of jacking system 1, have roller 7 and a retaining pawl 6 counterweight 8, rotatably mounted.Tooth bar 4 and section bar rail 5 distribute side by side.
As from Fig. 2 a, 2b, 2c and 3 see, prevent that the effect of the device 3 that falls is as follows.Being fixed on roller 7 on the retaining pawl 6 presses to section bar rail 5 by counterweight 8 (it also can substitute by spring) and is close to all the time on the section bar rail 5 when normal operation mobile.
Only when surpassing the specified speed of being determined by thrust, roller 7 just lifts from section bar rail 5 and embeds in the tooth bars 4 with retaining pawl 6 and make jacking system 1 stop.Thrust can be adjusted on the desired degree by the quality and the lever thereof of counterweight 8, thereby prevents that the device 3 that falls from only surpassing just triggering under the normal speed situation of jacking system 1.
The pure electronic or pneumatic drive part that mechanically works and need not complexity of this insurance of falling.
