Description

Inspection hammer

Technical Field

The utility model relates to the technical field of special equipment detection tools, in particular to a check hammer.

Background

The special equipment refers to boilers, pressure vessels (gas cylinders, the same applies below), pressure pipelines, elevators, hoisting machinery, passenger ropeways, large amusement facilities and special motor vehicles in a field (factory) which are related to life safety and high risk. Wherein the boiler, the pressure vessel (gas-containing bottle) and the pressure pipeline are pressure-bearing special equipment; the elevator, hoisting machinery, passenger ropeway and large-scale recreation facilities are electromechanical special equipment.

In order to ensure the normal operation of special equipment, workers need to carry tools such as a check hammer to check the equipment regularly. According to the sound and vibration generated by metal collision, the metal defects such as cracks, looseness defects, corrosion severity and weld quality can be accurately judged. When the boiler drum or the boiler liner, the pressure bearing part of the pressure container, the pressure pipeline and other parts which are easy to generate defects are knocked by metal, if the knocked object emits crisp and pure sound, the knocked object is better, and no obvious deterioration is found; if the knocked object produces a non-crisp and simple sound, the abnormal appearance of the metal component at the position is shown.

At present, most of the inspection hammers on the market are relatively single in structure, and generally comprise a hammer head and a handle connected with the hammer head, so that the inspection hammers are single in function. In view of the above drawbacks, some multifunctional inspection hammers have been invented, such as: a special equipment inspection tool hammer disclosed by publication No. CN 217007129U; a multifunctional inspection hammer disclosed in publication No. CN212218364U, etc., has the advantage of strong functionality.

In the same way, aiming at the defect of single structure of the checking hammer on the market, the utility model provides the checking hammer which is different from the existing multifunctional checking hammer structure, and has the advantages of strong functionality and applicability.

In order to solve the technical problems, the utility model adopts the following technical scheme:

an inspection hammer comprises a hammer head and a handle connected with the hammer head; the distinguishing features are that: the inspection hammer also comprises a graduated scale, a file and at least two feeler levers; the graduated scale and the file are arranged on the surface of the handle; the feeler gauge is arranged at the tail end of the handle, the tail end of the handle is provided with a containing groove for containing the feeler gauge, one end of the feeler gauge is hinged with the side wall of the containing groove, and the other end of the feeler gauge can be screwed out of the containing groove.

Further, the upper end of the hammer head is a conical head, and the lower end of the hammer head is a flat head.

Further, the head end of the handle is detachably connected with the middle part of the hammer head.

Further, the head end of the handle is connected with the middle part of the hammer head through threads, a screw hole is formed in the surface of the middle part of the hammer head, and threads matched with the screw hole are formed in the head end of the handle.

Further, a soft sleeve is arranged at the tail end of the handle.

Further, the graduated scale is arranged on the surface of the handle, which is close to the hammer head; the file is arranged on the surface of the handle, which is close to the soft sleeve.

Further, a magnet is embedded in the hammer head.

The beneficial effects of the utility model are as follows:

according to the checking hammer provided by the utility model, the graduated scale, the file and the feeler gauge are added on the structure of the existing checking hammer, and the size of a detection object can be rapidly measured through the graduated scale or used as a reference object for shooting and evidence obtaining; the detection surface can be filed by the file, the roughness is reduced, and accurate observation of defects (such as cracks, corrosion pits and the like) is facilitated; the corresponding thickness gauge is screwed out to measure the gap; after two thicker blades are screwed out and a measuring object (such as a welding groove) is attached, the angle value can be read out by comparing the two blades with the angle ruler, and therefore, compared with the existing checking hammer, the checking hammer has the advantages of being high in functionality and applicability.

Detailed Description

The present utility model is described below with reference to the accompanying drawings, and the specific embodiments described herein are for illustrating and explaining the present utility model, not for limiting the present utility model, and various modifications and improvements made by those skilled in the art to which the present utility model pertains without departing from the spirit of the design of the present utility model, should fall within the scope of the present utility model.

As shown in fig. 1 to 3, the inspection hammer of the present embodiment includes a hammer head 1, a handle 2, a scale 3, a file 4, and at least two plugs 5.

Wherein the upper end of the hammer head 1 is a conical head, and the lower end is a flat head. The cone head is made of high-carbon steel material, adopts a punctiform knocking mode, breaks hard objects, such as: scale on the surfaces of boilers, pressure vessels and pipelines, corrosion products and the like. The flat head is also made of high-carbon steel, and the area covering is effectively removed by adopting a ploughing and scraping mode, so that the detection of the detection surface is facilitated, for example: ultrasonic thickness measurement, macroscopic inspection, and the like.

The head end of the handle 2 is detachably connected with the middle part of the hammer head 1. In the embodiment, the head end of the handle 2 is connected with the middle part of the hammer head 1 through threads, the surface of the middle part of the hammer head 1 is provided with a screw hole 11, and the head end of the handle 2 is provided with threads matched with the screw hole 11, so that the assembly and the maintenance are convenient.

The soft sleeve 6 is arranged at the tail end of the handle 2, so that the handle 2 can be conveniently gripped, and the comfort level is improved.

The graduated scale 3 and the file 4 are both arranged on the surface of the handle 2. Specifically, the scale 3 is disposed on the surface of the handle 2 near the hammer head 1. The scale 3 can rapidly measure the size of the detection object or serve as a reference for photographing and evidence obtaining. The rasp 4 is arranged on the surface of the handle 2 adjacent to the soft sleeve 6. The detection surface can be filed by the file 4, the roughness is reduced, and the accurate observation of defects (such as cracks, corrosion pits and the like) is facilitated.

The feeler gauge 5 is arranged at the tail end of the handle 2, the tail end of the handle 2 is provided with a containing groove 21 for containing the feeler gauge 5, one end of the feeler gauge 5 is hinged with the side wall of the containing groove 21, and the other end can be screwed out of the containing groove 21. The thickness of the gauge piece of the feeler gauge 5 is 0.1-2 mm, and the clearance can be measured by unscrewing the gauge piece with corresponding thickness; the thicker two ruler sheets are screwed out, and after the two thicker ruler sheets are attached to a measuring object (a welding groove and the like), the angle value can be read out by comparing the two thicker ruler sheets with an angle ruler.

In addition, the magnet 7 is embedded in the hammer head 1 and can be used for rapidly distinguishing austenitic stainless steel from conventional ferromagnetic components; can be temporarily adsorbed on the surface of the ferromagnetic component to prevent the high altitude from falling.

In summary, the inspection hammer of the embodiment has the advantages of simple structure, strong functionality, strong applicability and portability, and can be applied to limited space and overhead operation.
