Description
Technical Field
The utility model relates to an annular U shaped steel support detects technical field, especially relates to annular U shaped steel support test bench.
Background
At present, the inspection of the U-shaped steel bracket is divided into factory inspection and type inspection. Before the U-shaped steel support leaves a factory, the U-shaped steel support must be subjected to factory inspection. The pattern verification is performed by a quality supervision and verification agency authorized by the country. According to the standard requirement, the U-shaped steel supports are required to be subjected to loading tests, and the loading capacity of each loading oil cylinder of the support test bed is not less than 250 KN. The test bench that adopts usually at present is annular test bench, installs a plurality of flexible hydro-cylinders according to certain rule around the circumferencial direction of ring on its ring inner wall, when detecting annular U shaped steel support, is connected annular U shaped steel support and flexible hydro-cylinder for annular U shaped steel support is located the intra-annular of annular test bench, and the length of rethread regulation flexible hydro-cylinder comes to apply pressure to annular U shaped steel support, thereby realizes the detection to annular U shaped steel support. However, the structure is complex, and the loaded annular test bed has high strength requirement and huge size. If the annular U-shaped steel support with the diameter of 2400mm needs to be detected, a test tool with the diameter of more than 4600mm is needed to apply 250KN radial force to the annular U-shaped steel support, so that the detection cost is increased, and the detection is complicated excessively.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model discloses an annular U shaped steel support test bench with hydro-cylinder loading mode adjustment, has pressure to change into the pulling force, just the utility model provides an annular U shaped steel support test bench structure is simpler, simple to operate and wider than prior art's application scope.
The technical scheme of the utility model as follows:
the annular U-shaped steel support test bed comprises an oil cylinder bearing seat and a plurality of loading oil cylinders which are arranged on the periphery of the oil cylinder bearing seat according to a certain rule, wherein a piston rod head of each loading oil cylinder is positioned on the same circumference which takes the central point of the oil cylinder bearing seat as the center of a circle, a loading oil cylinder base is arranged on the oil cylinder bearing seat, and a rod head of a piston rod of each loading oil cylinder is arranged on a loading tool for fixing the annular U-shaped steel support.
The loading tool comprises a double-lug seat connected with the rod head of the piston rod and a fixing device used for fixing the annular U-shaped steel.
Further, a rod end joint bearing is further installed between the rod head of the piston rod of the loading oil cylinder and the loading tool, the rod end of the rod end joint bearing is installed on the rod head of the piston rod through threaded connection, and the joint bearing of the rod end joint bearing is sleeved on a force transmission pin connected with two ears of the double-ear seat.
Fixing device is clamping device or sleeve structure for centre gripping annular U shaped steel support, only need when the inspection with U shaped steel pass the sleeve and assemble annular U shaped steel support again can.
Preferably, the oil cylinder bearing seat is of a twelve-prism structure, eight corresponding loading oil cylinders are in one group, two loading oil cylinders are in one group, a prism surface is arranged between each group of loading oil cylinders, and the two loading oil cylinders in each group are respectively arranged on the two adjacent prism surfaces.
The utility model has the advantages that: the utility model discloses test bench is located the inside of whole annular U shaped steel support when examining, through joint bearing, load round pin axle adjustment hydro-cylinder atress direction, simple structure, can satisfy the experimental loading requirement of U shaped steel completely, has still avoided the test bench problem with high costs that prior art adopted simultaneously.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
description of reference numerals: 1. a bearing seat of the oil cylinder; 2. loading an oil cylinder; 3. loading a tool; 4. a force transfer pin; 5. an annular U-shaped steel bracket; 6. and a rod end joint bearing.
Detailed Description
The invention is further described with reference to the accompanying drawings.
The annular U-shaped steel support 5 test bed comprises an oil cylinder force bearing seat 1 with a dodecagonal prism structure, the test bed corresponds to eight loading oil cylinders 2, the eight loading oil cylinders are divided into a group, a ridge surface is arranged between every two groups of loading oil cylinders 2, the two loading oil cylinders 2 in every group are respectively installed on the two adjacent ridge surfaces, the rod heads of the piston rods of the loading oil cylinders 2 are installed with the rod ends of rod end joint bearings 6 through threaded fit, and the joint bearings of the rod end joint bearings 6 are sleeved on force transmission pins 4 of two ears of a double-lug seat of a loading tool 3. The loading tool 3 further comprises a fixing device for fixing the annular U-shaped steel bracket 5, and the fixing device is of a sleeve structure or a clamping device.
When fixing device is the sleeve structure, only need to pass single U shaped steel the sleeve and be becoming annular U shaped steel support 5 structure with every U shaped steel, restart loading cylinder 2 shrink for annular U shaped steel support 5 receives one along the radial pulling force of annular U shaped steel support 5, thereby has realized the detection to annular U shaped steel support 5.
When fixing device is clamping device, only need to install whole annular U shaped steel support 5 on clamping device for clamping device tightly cliies annular U shaped steel support 5, and the shrink of restart load cylinder 2 makes annular U shaped steel support 5 receive one along the radial pulling force of annular U shaped steel support 5, thereby has realized the detection to annular U shaped steel support 5.
