[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.
[0024] Unless otherwise defined, the technical or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which this application belongs. The words "first", "second" and similar words used in the patent application specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "an" do not indicate a quantity limitation, but indicate the existence of at least one.
[0025] according to Figure 1 As shown, a multifunctional inspection hammer of the utility model example includes a hammer head 10, a hammer rod 20 and a multifunctional chisel 30 embedded in the hollow part 21 of the hammer rod 20. Compared with the problem that the inspection hammer in the prior art cannot properly handle the rust removal, corrosion removal and grinding treatment of the metal surface, the multifunctional inspection hammer of the present application integrates three tools, a hammer, a chisel and a screwdriver, into one, which is more effective in removing insulation layers, removing paint, removing rust and corrosion. Only one multifunctional inspection hammer is needed for processing to meet the thickness measurement requirements.
[0026] In this embodiment, a multifunctional testing hammer is provided, wherein the hammer rod 20 is hollow, and a hammer head 10 is fixedly provided on the top of the hammer rod 20 . One side of the hammer head 10 is a cylinder 12 , and the other side opposite thereto is a pointed cone 11 .
[0027] Specifically, the hammer rod 20 is a steel tube with a square cross section and a thickness of 1.5 mm to 2 mm. The four corners of the end of the hammer rod 20 connected to the hammer head 10 are arc transitions. The shape of the hammer rod 20 in the present application is not limited thereto, and can also be a common round steel tube shape.
[0028] Specifically, the multifunctional inspection hammer also includes a protective cover for the pointed cone 11, which makes it easy for the staff to pick up the inspection hammer without being injured by one end of the pointed cone 11 of the hammer head 10.
[0029] Specifically, the hammer head 10 is made of cemented carbide.
[0030] In this embodiment, the multifunctional chisel 30 is embedded in the hollow portion 21 of the hammer rod 20, and one end of the multifunctional chisel 30 is inserted into the hammer rod 20 to be sharpened, and the other end of the multifunctional chisel 30 is provided with a receiving cavity 31, and the bottom of the receiving cavity 31 is nested with the open end of the bottom of the hammer rod 20. A cover body is provided on the top of the receiving cavity 31 and a screwdriver head is fixed inside; wherein the screwdriver head includes a first screwdriver head 311 and a second screwdriver head 312 arranged in parallel, and the first screwdriver head 311 and the second screwdriver head 312 are both foldable screwdriver heads.
[0031] Specifically, the first screwdriver head 311 is a slotted screwdriver head, and the second screwdriver head 312 is a cross screwdriver head. In actual work, the screws on the thermal insulation layer can be removed by turning over the screwdriver head, so as to facilitate the safe removal of the thermal insulation layer.
[0032] Specifically, the sharpened end of the multifunctional chisel 30 serves as a pointed portion, which is wide and flat. Combined with the length of the chisel handle and the wide and thick accommodating cavity 31, the internal insulation layer can be further removed when struck by the hammer head 10 of the inspection hammer.
[0033] Specifically, the accommodating cavity 31 is a rectangular body and has a larger specification than the chisel body of the multifunctional chisel 30. When it is necessary to partially open a window on the metal insulation layer, the multifunctional chisel 30 and a hammer can be used together, and the accommodating cavity 31 is used for the end of the multifunctional chisel 30 that is hammered by the hammer. The cover of the accommodating cavity 31 is embedded, and a rubber protective layer is provided on the surface. The combined use of the chisel and the hammer can simplify the pre-process and reduce the workload.
[0034] Specifically, the bottom of the accommodating cavity 31 is connected to the bottom of the hammer rod 20 via a bead, so that the multifunctional chisel 30 can be easily taken out of and inserted into the hollow portion 21 of the hammer rod 20 .
[0035] Specifically, a plastic protective sleeve is provided at one end of the multifunctional chisel 30 close to the accommodating cavity 31 , which helps to enhance the friction when the worker grips it.
[0036] The working process of a multifunctional inspection hammer in this embodiment is as follows: in the pressure vessel inspection, it is necessary to remove the surface paint layer for thickness measurement or remove the rusty parts on the surface, and the multifunctional chisel 30 is pulled out from the hammer rod 20, and the surface paint layer is removed at the designated part with the chisel. When it is necessary to partially open a window on the metal insulation layer, the chisel and the hammer can be used together to replace the use of scissors or a cutter. Because some explosion-proof workshops need to obtain explosion-proof approval for the use of cutting machines, the combined use of the chisel and the hammer can simplify the pre-process and reduce the workload.
[0037] In summary, the technical solution of this application has the following beneficial effects:
[0038] 1. The inspection hammer of the present application has a pointed and flat hammer head at one end, and a removable chisel is embedded at the other end. The inside of the hammer rod is hollow to store the chisel. The chisel is sharpened at one end and can be used to cut aluminum or foam. The other end of the chisel is embedded with a foldable screwdriver head that can be flipped outward for removing small screws. The functional hammer of the present application has multiple functions and a high degree of functional centralization. It can complete multiple tasks during inspection work without adding equipment. The function of the inspection hammer greatly improves the appearance after the insulation layer is removed and the flatness after the paint layer is removed, which significantly improves the efficiency of the inspection work.
[0039] 2. The inspection hammer of the present application integrates three tools: a hammer, a chisel, and a screwdriver. A chisel is implanted at the tail end of the hammer rod, and two screwdriver heads (a flat head and a cross head) are integrated at the tail of the chisel. The screwdriver head can be flipped over for use. When the insulation layer and the paint layer need to be partially removed during on-site inspection, the chisel can be pulled out and used as a sharp tool for removing the insulation layer. When necessary, the bottom of the chisel can be hit with a hammer to increase the removal force, so that the insulation layer is removed with a smooth blade and the paint layer is removed more thoroughly and smoothly. When the insulation layer screws need to be removed during on-site inspection, the screwdriver head at the bottom of the chisel can be flipped over to work. At the same time, it is easy to carry and reduces the space occupied in the tool box.
[0040] 3. The screwdriver head of the present application is foldable. When a screw needs to be removed, the screwdriver head can be flipped outward to achieve the function of removing the screw.
[0041] The above are merely exemplary embodiments of the present application and are not intended to limit the protection scope of the present application. The protection scope of the present application is determined by the appended claims.
