Roller cage shoe rigidity test device with adjustable center height

Abstract

The invention discloses a roller cage shoe rigidity test device with the adjustable center height. The rigidity test device comprises a moving device, a rack, a vertical lifting device, and a horizontal control device. The moving device consists of brake-included heavy fixed truckles and brake-included heavy universal truckles and is installed at the bottom of the rack. The vertical lifting device includes a worm and gear lifting device, a height measuring device, and a vertical support frame and is fixed at the rack by the vertical support frame; and the worm and gear lifting device includes a lead screw connected with the height measuring device. The horizontal control device consists of a hydraulic control device, a displacement sensor, a pressure sensor, and a digital display instrument. The vertical lifting device and the horizontal control device control a push head guiding unit jointly; the push head guiding unit is connected with a pressing plate; and the pressing plate applies forces to a to-be-tested roller cage shoe horizontally. According to the test device, the center height of the test stand of the roller cage shoe can be adjusted; the test and measurement become conveniently; and the tedious operations of mounting and dismounting of roller cage shoes with different center heights can be avoided.

Description

technical field [0001] The invention belongs to the technical field of product testing, and in particular relates to a stiffness test device for lifting a roller lug of a guide device on a container in the field of coal mine production, and particularly relates to a stiffness test device with an adjustable center height. Background technique [0002] The hoisting container of mine shaft hoisting system generally adopts roller lugs as the motion guiding device. Reasonable roller lug stiffness characteristics are of great significance to the safe and efficient operation of the shaft hoisting system. However, roller lug manufacturers cannot provide product stiffness parameters. Because it is difficult to measure the stiffness of roller can lugs, at present, some analysis software is mainly used for measurement. The measurement process is a comparison process between the measured quantity and the standard or relative standard quantity. The standard quantity used for comparison m...

Problems solved by technology

[0005] Because different types of roller tank lugs have different base installation dimensions and center heights, the installation size adjustment of the base is easy to achieve. The center height was previously realized by increasing or decreasing the thickness of the supporting bottom plate. However, due to the large mass of the roller tank lugs, artificial It is very inconvenient to move and unload, therefore, the adjustment of the center height of the test bench is neither convenient nor accurate
