Problems solved by technology

[0003] The purpose of the present invention is to provide a length measuring and unloading device for steel wire ropes and a method for measuring and unloading steel wire ropes, so as to solve the problem that the steel wire ropes for elevators in the prior art are difficult to be straightened during the unfolding process during the cutting process, which causes the wire ropes to break. The length control is inaccurate; and during the unfolding process, the steel wire rope contacts and rubs against the ground, making the surface also polluted, sticking to dust, sand, etc., resulting in technical problems that the steel wire rope and traction sheave are easily worn after installation, reducing the service life

Embodiment 1

[0036] Such as Figure 1-4 As shown, a wire rope length gauge and feeding device includes a bracket 1, a measuring assembly arranged on the bracket 1, a guiding mechanism 5, a shearing mechanism 6 and a winding mechanism.

[0037] The measuring component is an electronic meter counter 13; the model of the electronic meter counter is HB961, purchased from Shanghai Renzhong Instrument Electric Co., Ltd.

[0038] The winding mechanism includes a driving motor 10, a first reducer 8, a rotating sliding device 7 and a drum 2. The motor 10 drives the first sliding sleeve 71 to rotate by driving the first reducer 8, and the first sliding sleeve 71 passes through the bearing Rotationally connected with the bracket 1; the inner wall of the first sliding sleeve 71 is provided with a first limiter, the first sliding sleeve 71 is set on the sliding shaft 72, and the outer surface of the sliding shaft 72 is provided with a second limiter 73 along its length direction , the second limiter i...

Embodiment 2

[0052] The length counting and blanking method based on the above-mentioned steel wire rope length counting and blanking device comprises the following steps:

[0053] Step 1. Place the entire wire rope on the turntable, take out the tap of the wire rope, pass through the electronic meter, the shear ring of the shear mechanism, and the two rollers, and then fix it on the drum;

[0054] Step 2. Start the motor to drive the drum to rotate. The wire rope is wound on the drum after the length is measured and recorded by the electronic meter counter. The wire rope is in a tensioned state; When moving, the steel wire rope is driven by the two rollers to wind upwards from the lower end of the drum. After winding one layer to the upper end of the drum, the drive assembly drives the slide bar to move down, and the steel wire rope is driven by the two rollers to wind evenly downwards from the upper end of the drum. repeat;

[0055] Step 3: When the length of the wire rope is measured b...

Abstract

The invention discloses a steel wire rope length measurement and blanking device and a steel wire rope length measurement and blanking method. The steel wire rope length measurement and blanking device comprises a support, a measurement assembly, a cutting mechanism and a rolling mechanism, wherein the measurement assembly, the cutting mechanism and the rolling mechanism are arranged on the support. In the steel wire rope length measurement and blanking process, after measurement and length recording are conducted through an electronic meter gauge, a steel wire rope is wound on a roller and isin the tensioned state; when the length, measured through the electronic meter gauge, of the steel wire rope reaches the set length, the steel wire rope is cut off through the cutting mechanism, andat the moment, the length of the steel wire rope wound on the roller is the set length; then, the roller is driven by a piston rod of a first piston cylinder to move downwards, the steel wire rope wound on the roller is separated from the roller, an at the moment, measurement and blanking of the steel wire rope are completed. After being unwound, the steel wire rope is wound on the roller; the roller is driven by a motor to rotate for secondary rolling, and the steel wire rope is easy to straighten; and the length of the steel wire rope is measured through the electronic meter gauge, the length control precision of the steel wire rope is high, and the error of every 100 meters does not exceed one centimeter.

Description

technical field [0001] The invention belongs to the technical field of steel wire ropes for elevators, and in particular relates to a length measuring and unloading device for steel wire ropes and a length counting and unloading method for steel wire ropes. Background technique [0002] Elevator traction uses at least two wire ropes, usually five wire ropes. Each wire rope independently passes through the traction wheel and guide wheel, and one end is connected to the car, and the other end is connected to the counterweight. The tension of all wire ropes should be equal when loaded, and the error should not exceed 5% according to the standard requirements. Therefore, at least it is necessary to ensure that the length of each traction wire rope is equal. The length of the wire rope is related to the hoisting height of the elevator. The hoisting height of the elevator is not completely consistent with the design drawing on the installation site. Therefore, it is best to deter...
