Tight pulley groove radial runout detection tool rises

Technical Field

The utility model relates to a detection tool technical field especially relates to a tight pulley groove runout detection tool rises.

Background

When the wheel groove of the tension wheel for the elevator is processed, certain errors and concave-convex conditions inevitably occur. The outer circle surface of the pulley groove needs to be wound with a steel wire rope, the radial run-out of the pulley groove needs to provide the maximum allowable upper limit during design, and exceeding the upper limit means that the steel wire rope matched with the tension pulley can shake impermissibly during operation, so that the comfort of a passenger is influenced, and the feeling is more obvious when the elevator operates quickly.

Based on this, tight pulley need detect the runout in the wheel groove after the processing is accomplished. At present, during detection, a mandrel penetrates through a shaft hole of a tension wheel, two V-shaped irons are placed on a detection platform, two ends of the mandrel are placed in V-shaped grooves of the V-shaped irons, a gauge seat of a dial gauge is fixed on the detection platform, a measuring head of the dial gauge abuts against the outer circular surface of the wheel groove, an inspector rotates the tension wheel for a circle by hand, the minimum value and the maximum value of the dial gauge are read, and the difference value is the measured value of radial runout of the tension wheel.

The problems are that: when the tension wheel is rotated by a hand, the mandrel can transversely move between the two V-shaped irons while the tension wheel rotates, the wheel groove is of a structure with a V-shaped cross section and an arc-shaped groove bottom, and when the wheel groove transversely moves, a point measured by the measuring head is not on the circumference of a circle, so that a large measuring error is generated, and therefore in order to avoid the situation, an inspector needs to additionally provide transverse force for the tension wheel to lean against one of the V-shaped irons when the tension wheel rotates, certain difficulty is added to measurement, and the accuracy of a measuring result is also influenced.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an utilize magnetic component's magnetic attraction to adsorb and live the dabber, make tight pulley that rises that lateral shifting can not appear at the rotation in-process wheel groove runout detection tool rises.

Therefore, the application provides the following technical scheme: a tensioning wheel groove radial runout detection jig comprises a base, wherein two vertical plates are fixedly arranged on the base, and the two vertical plates are symmetrically arranged in the middle of the base; the upper part of the inner side of each vertical plate is provided with a supporting piece for supporting the mandrel of the tension wheel, the top surface of one vertical plate is provided with a boss protruding upwards, and the inner side wall of the boss is fixedly provided with a magnetic part for adsorbing the mandrel.

Furthermore, a positioning groove which traverses the upper end face is formed in the base, a downward protruding positioning block which is matched with the positioning groove is arranged on the lower end face, which is in contact with the base, of the vertical plate, and the positioning block is clamped in the positioning groove.

Furthermore, the supporting pieces are two rolling bearings, the two rolling bearings are fixed on the inner side walls of the two vertical plates through short shafts which are arranged in the inner rings of the bearings in a penetrating mode, and the axial leads of the two short shafts are located in the same plane parallel to the base.

Further, the magnetic member is a permanent magnet made of neodymium iron boron.

The utility model has the advantages of it is following:

1. the utility model discloses a magnetic part makes tight pulley that rises can not produce the lateral deviation in two sets of support piece at rotatory in-process to the adsorption affinity of dabber, simple structure, simple operation.

2. Through set up the constant head tank on the base, set up the locating piece with the constant head tank adaptation in the bottom of riser, the process of adjusting two sets of support piece aligning when having saved the installation riser.

3. Two rolling bearings which are installed in parallel are used as supporting pieces for supporting the tension wheel, so that the rotation of the tension wheel is smoother.
