Description

A kind of rolling cage shoe static stiffness test device

Technical field

The utility model belongs to product testing device, is specially the static stiffness test device of guide piece rolling cage shoe on the hoisting conveyance of coal production field.

Background technology

The hoisting conveyance of mine vertical shaft elevator system generally adopts rolling cage shoe as linear motion guide device, and its stiffness parameters and rigidity characteristic are the very important technical indicators of rolling cage shoe.Because, if rigidity is excessive, then rolling cage shoe absorbs the reduced capability of vibration, and hoisting conveyance aggravates along vibration in cage guide operational process under rolling cage shoe guiding, the dynamic loading that is subject to of hoisting conveyance, cage guide and rolling cage shoe body strengthens, and the probability of premature failure or damage strengthens; If rigidity is too small, be out of shape excessive in rolling cage shoe loading process, the probability that hoisting conveyance body (as fixing cage shoe, disk body etc.) contacts with cage guide strengthens, thus the probability of hoisting conveyance and cage guide premature failure or damage strengthens, and elevator system security reduces.

But for a long time, rolling cage shoe production firm can not provide product stiffness parameters, reason one is inadequate to stiffness parameters understanding of importance; Two is that stiffness measurement acquires a certain degree of difficulty, and pair roller applies test load, owing to rotating unstability trend without there is roller under clamp position, may bring difficulty to surveying work.Like this, applying unit only judges rolling cage shoe quality good or not by rule of thumb, even excessively pays close attention to " serviceable life " of rolling cage shoe, evaluates rolling cage shoe quality famine scientific basis; Due to rolling cage shoe stiffness parameters and rigidity characteristic data deficiency, be engaged in the prediction that elevator system and hoisting conveyance product research designer cannot carry out oscillating load, and only rely on the hypothesis of linear rigidity, scientific design associated equipment or equipment cannot be accomplished, the pulling speed of elevator system is difficult to reach raising, security reduces relatively; In addition, rational rolling cage shoe rigidity characteristic curve is conducive to reducing oscillating load under the premise that security is guaranteed, improves equipment and equipment quality.

As can be seen here, need a kind of device and before rolling cage shoe dispatches from the factory or uses, it is detected, provide its stiffness parameters, rigidity characteristic curve, to reach optimum matching with the environment (speed, load) used, improve equipment and equipment quality; Also be conducive to scientific evaluation rolling cage shoe product quality simultaneously

Utility model content

For the problems referred to above, the purpose of this utility model there is provided a kind of static stiffness test device of rolling cage shoe, the Static stiffness solving rolling cage shoe is difficult to the problem detected, Static stiffness test is carried out by this device pair roller cage shoe, grasp science data, thus improve rolling cage shoe product quality and elevator system equipment quality.

The technical solution adopted in the utility model is as follows:

A kind of static stiffness test device of rolling cage shoe, comprise base, on described base upper surface, one end is provided with vertical bracing frame, vertical bracing frame is fixed with T-slot base plate to the base upper surface of the other end, T-slot base plate is provided with installing plate, installing plate is provided with the elongated hole corresponding with rolling cage shoe position of mounting hole, installing plate is fixedly connected with by T-slot securing member with T-slot base plate, guide piece of cutting somebody's hair is provided with in described vertical bracing frame, cut somebody's hair and be inserted through guide piece of cutting somebody's hair, cut somebody's hair and to be slidably matched with guide piece of cutting somebody's hair, can move in the horizontal direction, connecting fluid of cutting somebody's hair cylinder pressure, the Hydraulic Station of described hydraulic cylinder connects industrial computer.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model carries out Static stiffness test by this device pair roller cage shoe, grasps science data, thus improves rolling cage shoe product quality and elevator system equipment quality; Installing plate is provided with elongated hole, and the arbitrary dimension rolling cage shoe realized within the scope of certain size is fixing on floor, can carry out clean rigidity test various rolling cage shoe, obtains Static stiffness parameter and the Static stiffness characteristic curve of product; The industrial control system of system can read stressed automatically---displacement relation curve, derive and printed product test data sheet.

Embodiment

See accompanying drawing, a kind of static stiffness test device of rolling cage shoe, comprise base 1, on base 1 upper surface, one end is provided with vertical bracing frame 9, vertical bracing frame 9 is fixed with T-slot base plate 2 to base 1 upper surface of the other end, T-slot base plate 2 is provided with installing plate 4, installing plate 4 is provided with the elongated hole corresponding with rolling cage shoe position of mounting hole, installing plate 4 is fixedly connected with by T-slot securing member 5 with T-slot base plate 2, guide piece 8 of cutting somebody's hair is provided with in described vertical bracing frame, cut somebody's hair and 7 be inserted through guide piece 8 of cutting somebody's hair, cut somebody's hair and to be slidably matched with guide piece of cutting somebody's hair, can move in the horizontal direction, connecting fluid of cutting somebody's hair cylinder pressure 10, the Hydraulic Station 11 of described hydraulic cylinder connects industrial computer 12, the elongated hole being provided with correspondence at rolling cage shoe position of mounting hole of installing plate 4, for the test rolling cage shoe of the different size within the scope of fixing certain size, there is fixing hole at its two ends, for installing T-slot securing member, fix with T-slot base plate, installing plate 4 thickness sets according to rolling cage shoe height, to ensure rolling cage shoe center line and to cut somebody's hair center line point-blank.Adopting this method can realize by changing easy installing plate 4, realizing the installation to different size test rolling cage shoe and test.

Cut somebody's hair 7 with cut somebody's hair guide piece 8 activity coordinate, can move in the horizontal direction, under the promotion of hydraulic cylinder, cut somebody's hair and 7 to contact with rolling cage shoe 3 and exert a force, by rolling cage shoe crimp, its distortion had both comprised the elastic deformation of rolling cage shoe outer ring, and also comprising the distortion of its metal support, is the bulk deformation of rolling cage shoe.7 certain horizontal force can be born when cutting somebody's hair and leading in guide piece 8, so can ensure that, when pair roller cage shoe 3 exerts a force, do not deflect phenomenon owing to cutting somebody's hair.
