Abstract
The utility model belongs to a detection apparatus for steel grating horizontal pole welding firmness. The problems to be solved are that: the welding firmness between the transverse rod and the flat steel has no scientific detection means, the crowbar can only be used for qualitative test by experience, the data obtained by using the torque wrench is only that the moment can not directly measure the force borne by the welding point of the transverse rod and display the data, and the laboratory detection can not ensure the accuracy, the science, the time and the labor are wasted. The key points of the technical scheme adopted for solving the technical problem are as follows: the hydraulic jack is arranged above the steel grating, the tension sensor is connected to the lower portion of a hanging claw of the hydraulic jack, the testing draw hook is connected to the lower portion of the tension sensor, the testing draw hook is used for hooking a cross rod welded to the steel grating flat steel, the hydraulic jack is used for drawing the cross rod welded to the steel grating flat steel through the tension sensor and the testing draw hook, and the tension sensor is connected with the tension measuring instrument to display the tension value of the real-time load of the hydraulic jack. The method is suitable for detecting the welding firmness between the cross rod and the flat steel of the finished steel grating on site.
Description
Technical Field
The utility model belongs to detection device, especially a detection device of steel grating horizontal pole welding firmness.
Background
The production of the existing steel grating plate generally adopts a steel grating plate piezoresistive welder to weld a transverse rod and flat steel, dozens of welding spots are simultaneously welded every time, and hundreds of welding spots are arranged on one steel grating plate. The welding firmness between the cross rod of the finished steel grating and the flat steel is difficult to judge, scientific detection means is not provided, spot inspection can only be carried out by prying with a pry bar, and the welding firmness is judged according to the strength and the feeling of a detector; or a torque wrench is used for carrying out a damage test on the cross bar of the steel grating. The former can only be qualitatively tested by experience by using a crow bar; the data obtained by using the torque wrench in the latter is only torque (unit is Newton. meter), and the data of the strength of the welding point of the cross bar can not be directly measured and the data of the firmness of the welding point of the cross bar can not be displayed. If send the steel grating to the laboratory and detect, because the sample quantity limits, can not guarantee to detect accurate science of data to waste time and energy.
Disclosure of Invention
The utility model aims at providing a detection apparatus for steel grating horizontal pole welding firmness to solve the background art existence: the welding firmness between finished steel grating horizontal pole and the band steel does not have scientific detection means, uses the crow bar can only rely on experience qualitative test, and the data that uses torque wrench to reachd is the moment can't directly record the power that horizontal pole solder joint department bore and show its firmness, send the steel grating to the laboratory and detect and can not guarantee to detect the accurate science of data to waste time and energy. The technical scheme for solving the technical problem is as follows: the utility model provides a detection apparatus for steel grating horizontal pole welding firmness, its characterized in that: the hydraulic jack is arranged above the steel grating, the tension sensor is connected to the lower portion of a hanging claw of the hydraulic jack, the testing draw hook is connected to the lower portion of the tension sensor, the testing draw hook is used for hooking a cross rod welded to the steel grating flat steel, the hydraulic jack is used for drawing the cross rod welded to the steel grating flat steel through the tension sensor and the testing draw hook, and the tension sensor is connected with the tension measuring instrument to display the tension value of the real-time load of the hydraulic jack.
Compared with the prior art, the utility model has the beneficial effect that: by adopting the technical scheme, when in use, the hydraulic jack is started to draw the cross rod welded on the steel grating flat steel through the tension sensor and the test draw hook, and the real-time stress of the cross rod is directly read out through the tension measuring instrument connected with the tension sensor; when the cross rod and the bearing flat steel are in a separated state, the stress is maximum, the measured value can be locked on the tension measuring instrument, and the welding firmness value can be read simply and conveniently. Like this, realized the spot test steel grating horizontal pole welding firmness, it is scientific directly perceived to detect numerical value, convenient operation, and the configuration of device is simple and convenient and light in weight.
Description of the drawings: fig. 1 is a schematic structural view of the present invention, and fig. 2 is a left side view of fig. 1.
The specific implementation mode is as follows:
example (b): referring to fig. 1 and 2, a detection device for welding firmness of a cross bar of a steel grating is characterized in that: the hydraulic jack 2 is arranged above the steel grating 1, the tension sensor 4 is connected below a hanging claw of the hydraulic jack 2, the testing draw hook 3 is connected below the tension sensor 4, the testing draw hook 3 hooks a cross rod welded on a flat steel of the steel grating 1, the hydraulic jack 2 pulls the cross rod welded on the flat steel of the steel grating 1 through the tension sensor 4 and the testing draw hook 3, and the tension sensor 4 is connected with the tension measuring instrument 5 to display the tension value of the real-time load of the tension measuring instrument.
