Abstract
The utility model discloses a weight sensor of a tower crane. The weight sensor is characterized by being provided with two static pulleys and a movable pulley which are arranged triangularly, wherein the left static pulley and the right static pulley are fixed at two ends of a static pulley bracket through pin rolls, a weight sensor is arranged at the lower part of the static pulley bracket, is arranged between the two static pulleys, is fixed on the static pulley bracket 5, and locked through weight sensor lock pins (7), a weight sensor lead is led out from the weight sensor, an installing shaft is arranged at the bottom of the static pulley bracket, the movable pulley is fixed at the upper end of the movable pulley bracket through a pin roll, a steel rope is arranged above the two static pulleys and below the movable pulley so that the steel rope generates an included angle of 163-165 DEG. The weight sensor of the tower crane, provided by the utility model, is suitable for tower cranes of various types and models, is capable of directly weighing a heavy to be hoisted, and has the characteristics of reasonable design, simple structure, convenience in installation and accuracy in weighing.
Description
Technical field
The utility model relates to a kind of tower crane weight sensor.
Background technology
At present, domestic tradition in the prior art adopts leaf spring type weight sensor, for hook scale and spring balance, the weight of lifting weight is weighed, but it can not be weighed to the weight of tower crane lifting weight, and the tower crane of any kind and model all can not be weighed to the weight of lifting weight.
Summary of the invention
The utility model has overcome the defect of above-mentioned existence, and object is can directly to the weight of lifting, weigh for solving tower crane, and a kind of tower crane weight sensor is provided.
The utility model tower crane weight sensor content Description:
The utility model tower crane weight sensor, it is characterized in that: be by quiet pulley, movable pulley, bearing pin, weight sensor, quiet pulley bracket, moving pulley bracket, weight sensor lock pin, installation shaft, steel rope and weight sensor wire form, be provided with 2 quiet pulleys and 1 movable pulley, be triangularly arranged, 2 the quiet pulleys in left and right are fixed on the two ends of quiet pulley bracket by bearing pin, the bottom of quiet pulley bracket is provided with weight sensor, weight sensor is arranged on the centre of 2 quiet pulleys, be fixed on quiet pulley bracket, by weight sensor lock pin, lock, weight sensor is drawn weight sensor wire, the bottom of quiet pulley bracket is provided with installation shaft, movable pulley is fixed on the upper end of moving pulley bracket by bearing pin, steel rope is arranged on the top of two quiet pulleys and the below of movable pulley, makes steel rope produce 163 degree-165 degree angles.
The utility model tower crane weight sensor, is applicable to the tower crane of all kinds and model, can directly to the weight of lifting, weigh, have reasonable in design, simple in structure, easy for installation, weigh feature accurately.
Accompanying drawing explanation
Fig. 1 is tower crane weight sensor structural representation;
Fig. 2 is tower crane weight sensor structure back view;
In figure: the 1st, quiet pulley, the 2nd, movable pulley, the 3rd, bearing pin, the 4th, weight sensor, the 5th, quiet pulley bracket, the 6th, moving pulley bracket, the 7th, weight sensor lock pin, the 8th, installation shaft, the 9th, steel rope, the 10th, weight sensor wire.
The specific embodiment
The utility model tower crane weight sensor is achieved in that below in conjunction with accompanying drawing and illustrates.
See Fig. 1, Fig. 2: tower crane weight sensor, by quiet pulley 1, movable pulley 2, bearing pin 3, weight sensor 4, quiet pulley bracket 5, moving pulley bracket 6, weight sensor lock pin 7, installation shaft 8, steel rope 9 and weight sensor wire 10 form, being provided with 2 quiet pulleys 1 is triangularly arranged with movable pulley 2, 2 the quiet pulleys 1 in left and right are fixed on the two ends of quiet pulley bracket 5 by bearing pin 3, the bottom of quiet pulley bracket 5 is provided with weight sensor 4, weight sensor 4 is arranged on the centre of 2 quiet pulleys 1, be fixed on quiet pulley bracket 5, by weight sensor lock pin 7, lock, weight sensor 4 is drawn weight sensor wire 10, the bottom of quiet pulley bracket 5 is provided with installation shaft 8, movable pulley 2 is fixed on the upper end of moving pulley bracket 6 by bearing pin 3, steel rope 9 is arranged on the top of two quiet pulleys 1 and the below of movable pulley 2, makes steel rope 9 produce 163 degree-165 degree angles, when steel rope is strong, upwards walking of movable pulley 3, makes weight sensor 4 distortion produce data.
On measuring tower crane during weight, because steel rope 9 is passing above two quiet pulleys 1 and below movable pulley 3, make steel rope 9 on 3 pulleys, produce the angle of 163 degree-165 degree, when slinging weight, angle increases, by movable pulley 3, drive upwards walking of weight sensor 4, make weight sensor 4 produce data, by the different voltage of different stressed generations, measure different numerical value.The weight sensor wire 10 that weight sensor 4 is drawn is connected with main frame.
The utility model tower crane weight sensor, is applicable to the tower crane of various types of and model, can directly to the weight of lifting, weigh, have reasonable in design, simple in structure, weigh feature accurately.
