Description
Technical Field
The utility model relates to a jack-up overhead traveling crane wheel footpath wearing and tearing on-line measuring ruler belongs to jack-up overhead traveling crane detection tool technical field.
Background
The hoisting crown block wheel is a mechanism for bearing the crown block during operation, and in the using process, the wheel tread is contacted with the top surface of the track to generate friction, which is the friction necessary for the crown block to operate and inevitably causes the abrasion of the wheel tread and the top surface of the track. The wheel diameter of the wheel is reduced due to the abrasion of the tread, and the running instability of the crown block can be caused if the wheel diameters of the wheels at all positions of the crown block are inconsistent, such as the whole crown block running askew, the rail gnawing, the abnormal vibration and the like, and the traffic safety accident can be caused in serious conditions. Therefore, the wheel diameter needs to be periodically detected.
At present, tools for detecting wheel diameters of crown blocks mainly comprise precision pi-ruler tools and caliper tools, which can accurately measure the wheel diameters, but can only measure off-line and cannot measure on-line, namely, the wheel diameters can only be measured after the wheel is detached from the crown block, so that the significance of periodic detection is lost. The maintenance personnel usually adopt visual methods or measure the radial difference between the tread and the wheel rim to determine the wheel diameter, and the methods have low measurement accuracy, large measurement error, higher requirement on the technical quality of the personnel and great limitation.
Disclosure of Invention
The utility model aims at providing a jack-up overhead traveling crane wheel footpath wearing and tearing on-line measuring chi, under the condition of not dismantling the wheel, through the wearing and tearing condition of measuring the wheel tread, calculate and reach the wheel footpath to reach convenient easy, satisfy measurement accuracy's purpose, measurement accuracy can reach 0.1mm, improve and detect the operating efficiency and detect the precision, but the wide application has very high spreading value in the on-line measuring of various double rim wheels, the above-mentioned problem that exists in the background art has been solved effectively.
The technical scheme of the utility model is that: an online detection ruler for wheel diameter abrasion of a wheel of a crane overhead crane comprises a sliding ruler, a scale, a support, a cushion block and a knob, wherein the support is of an H structure and is provided with four support legs, the included angle between the two support legs on the same side is 120 degrees, the end part of each support leg is connected with the cushion block through a through pin, and the cushion block can freely rotate around the through pin; the scale is fixed in the middle of the support, the sliding ruler is clamped in the scale in a sliding mode, the knob is arranged on the scale, and the sliding ruler is fixed through the knob; the sliding ruler and the scale are marked with scales.
The minimum graduation of the scale on the sliding ruler body is 1mm, 10 small equal divisions are arranged on the sliding ruler body, and the total length is 9 mm.
The utility model has the advantages that: under the condition of not disassembling the wheel, the wheel diameter of the wheel is calculated by measuring the abrasion condition of the wheel tread, so that the purposes of convenience and easiness and meeting the measurement precision are achieved, the measurement precision can reach 0.1mm, the detection operation efficiency and the detection precision are improved, the method can be widely applied to the online detection of various double-rim wheels, and the method has high popularization value.

Detailed Description
In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the following will combine the drawings in the embodiment to clearly and completely describe the technical solution in the embodiment of the present invention, and obviously, the embodiment described is a small part of the embodiment of the present invention, rather than the whole embodiment, based on the embodiment of the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
An online detection ruler for wheel diameter abrasion of a wheel of a crane overhead crane comprises a sliding ruler 1, a scale 2, a support 3, a cushion block 4 and a knob 5, wherein the support 3 is of an H-shaped structure (similar to an H-shaped structure), four support legs are arranged, an included angle between two support legs on the same side is 120 degrees, the end part of each support leg is connected with the cushion block 4 through a through pin, and the cushion block can freely rotate around the through pin; the scale 2 is fixed at the center of the support 3, the sliding ruler 1 is clamped in the scale 2 in a sliding manner, the knob 5 is arranged on the scale 2, and the sliding ruler 1 is fixed through the knob 5; the sliding ruler 1 and the scale 2 are marked with scales.
The minimum graduation of the scale on the sliding ruler 1 is 1mm, the scale 2 is provided with 10 small equal divisions, and the total length is 9 mm.
The sliding ruler 1 is clamped in the scale 2 and can freely slide, the cooperation of the sliding ruler 1 and the scale 2 is similar to the cooperation of a vernier and a main ruler in a vernier caliper, scales are marked on the sliding ruler 1 and the scale 2, the minimum graduation of the scales on the body of the sliding ruler 1 is 1mm, 10 small equal divisions of the scales on the body of the scale 2 are provided, and the total length is 9 mm. When reading, the scale mark opposite to the ruler body is read from the 0 line of the ruler, and the precision is 0.1 mm. The scale 2 is provided with a knob 5 which can fix the sliding ruler 1. Seen from the top, the support 3 is similar to an H-shaped structure, four support legs are designed, the scale 2 is fixed in the center of the support 3, the included angle between the two support legs on the same side is 120 degrees, the end part of each support leg is connected with the cushion block 4 through a through pin, and the cushion block can freely rotate around the through pin.
In practical application, will the utility model discloses on jack-up overhead traveling crane wheel, four cushions are placed on the wheel rim (because the wheel rim can not appear wearing and tearing, so use this as the measuring basis), adjust the sliding ruler, until chi point and wheel tread contact, screw up the knob, fixed sliding ruler. The slide rule was removed for reading and recording. The method comprises the steps of carrying out first measurement after a new wheel is installed, carrying out periodic measurement according to a point inspection period, and calculating the tread wear loss in the measurement period by comparing adjacent two measurement values to further obtain the wheel diameter size of the current wheel.
