When the control of car hosit elevator limit for height is by hooking up, after suspension hook 101 touching height limit switch 102, signal being transferred to the torque limiter of tyre crane 109 by the long cable 106 of survey and making corresponding process.
At present, all both at home and abroad hoisting crane manufacturer (Xu work, middle, 31, De Mage etc.) all adopt the long and elevator limit for height limit method of the survey of the type, this kind of mode needs the long cable 106 of expensive survey and winding box 107, and be contained in armed lever outside due to device side, in lifting operation, easily there is the situation of scratch cable, when cable reparation or Seasonal Temperature Difference change, also long value to be surveyed by the correction of adjustment potential device, more loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of structure simple, survey rectangular just, accurately, limit for height controls safer actv. the torque limiter of tyre crane and surveys long with elevator limit for height control system.
For achieving the above object, a kind of the torque limiter of tyre crane designed by the utility model surveys long and elevator limit for height control system, comprise the suspension hook be connected with winch by steel rope, described steel rope is walked around and is installed on telescoping boom arm head pulley foremost, and its special character is:
Described telescoping boom is hollow structure, above described telescoping boom foremost interior location, vertically pull back spring is installed, the described pull back spring other end is vertically connected with plastic dam, described plastic dam lower end has aperture and is connected with spacing hauling rope one end, the described spacing hauling rope other end is connected through the heavy ring of telescoping boom lower end aperture and height limit, the heavy ring set of described height limit is established on a steel cord, described telescoping boom foremost internal end surface is provided with mesh sponge light absorbent, described telescoping boom extreme end internal end surface is provided with laser sensor, described laser sensor is connected by the communications cable with limiter of moment.
Further, described pull back spring is arranged with spring orienting sleeve, spring orienting sleeve can the swinging of restraining spring.
Preferably, described spacing hauling rope is also provided with spacing pulley through on the position of telescoping boom lower end aperture, described spacing hauling rope is walked around spacing pulley and is connected with the heavy ring of height limit, and spacing like this pulley can reduce the friction of spacing hauling rope and described telescoping boom lower end aperture.
The concrete working process of the utility model is as follows:
The laser alignment plastic dam that laser sensor sends, the CPU control laser ranging module of installing in limiter of moment feeds back to limiter of moment and carries out correlation computations after time interval measurement one secondary data, when telescoping boom stretches, can there is respective change in the length value of laser measurement;
In the plastic dam of installing foremost of telescoping boom, balance under the application force that height limit weighs ring and pull back spring, when suspension hook does not rise to limit height, laser is just in time irradiated in plastic dam, when the heavy ring of suspension hook touching height limit, plastic dam under the effect of pull back spring pulling force on move, laser straight is mapped on mesh sponge light absorbent, survey long data and be changed to infinity, laser length measurement module is to limiter of moment signal transmission, limiter of moment controls telescoping boom and winch and relevant electromagnetic valve, suspension hook is made no longer to increase, reach the object of protection car hosit, when off the hook, suspension hook declines, and when disengaging with the heavy ring of height limit, the heavy ring of height limit overcomes spring force by the drop-down plastic dam of spacing hauling rope, and laser is met plastic dam back reflection and recovered to survey long function, limiter of moment Controlling solenoid valve de-preservation.
The utility model has the advantage of: due to laser sensor is placed in telescoping boom inside, can not disturb by the factor such as light wave or sleet when making to survey long, survey long more simple, accurate; And it is effectively safer that the increase of laser sensor also makes the utility model limit for height control, survey long relevant device owing to substituted for spiral, fundamentally avoid in lifting operation the situation occurring scratch cable.
