Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1-5, a drum hammer for detection comprises a hammer head 2 and a hammer handle 5, wherein a groove a3 is formed in the top of the hammer head 2; the bottom of the hammer head 2 is provided with a hammer tip 1; a movable rod 4 is arranged between the hammer head 2 and the hammer handle 5; one end of the hammer handle 5 is provided with a movable weight 6; one end of the movable rod 4 is fixedly connected with the hammer head 2, and the other end of the movable rod is embedded into the hammer handle 5 and movably connected with the hammer head; the tail part of the hammer handle 5 is provided with a groove B; the movable weight 6 is connected with the groove B in a matching way.
The movable rod 4 is provided with scale marks 8. The scale marks 8 are used for adjusting the length of the movable rod 4 in the hammer handle 5, so that the distance between the hammer head 2 and the hammer handle 5 can be conveniently adjusted.
And a rubber ring is arranged at the joint of the hammer handle 5 and the movable rod 4. The rubber ring is used for fixing the movable rod 4 and preventing the movable rod 4 from sliding up and down randomly in the using process.
And the grooves A3 and B are internally provided with internal threads respectively. The thread in the groove A3 is matched with the external thread of the movable weight 6, so that the movable weight and the movable weight are convenient to connect. The internal thread in the groove B is matched with the external thread of the boss 10, so that when the movable weight 6 is not used, the movable weight 6 can be arranged at the tail part of the hammer handle 5, and the movable weight can be conveniently used when needed.
The hammer head 2 is provided with a small hole 7. The function is as follows: half pieces of chalk are clamped in the small holes 7, so that the chalk is used for marking after one region is detected conveniently, and repeated detection of the same region is prevented.
One end of the movable weight 6 is provided with a boss 10, and the other end is provided with a concave hole 9. The function of the projection 10 is to connect the groove B and the mating connection installed in the hammer head 2. The effect of shrinkage pool 9 is in supplementary twisting movable weight 6 into tup 2, improves the firm degree of connection, also takes out movable weight 6 when conveniently not using simultaneously.
And external threads with different diameters are respectively arranged on the movable weight 6 and the boss 10. The external thread is used for matching with the internal thread, so that the movable weight 6 is conveniently connected with the groove A3 or the groove B.
The surface of the hammer handle 5 is provided with anti-skid convex points. The friction force between the hand and the hammer handle 5 is increased, and the holding feeling is improved.
The weight of the hammer head 2 was set to 10 g. The weight of the movable weight 6 was set to 15 g. The movable weight 6 is used when the weight of the hammer head 2 needs to be increased.
The working principle is as follows: when in use, the drum hammer for detection with different weights is selected according to different purposes. If the hammer is used for detecting the hollowing area or degree of a cement mortar slope layer, a leveling layer and a surface layer with the thickness of less than 20mm and for detecting the hollowing area or degree of a small ceramic tile, a sounding hammer for detecting 10g is selected. The length of the movable rod 4 is adjusted, the friction force between the movable rod 4 and the rubber ring is utilized for fixing, the using length of the drum hammer for detection is determined, and then the hammer head 2 is directly used for detection. If the hollowing area or degree of a large stone panel or a large ceramic tile needs to be detected, and the hollowing area or degree of a thick cement mortar slope finding layer and a thick leveling layer or a concrete surface layer with the thickness of about 40mm needs to be detected, a 25g sounding hammer for detection is selected. The specific method is that the movable weight 6 which is connected with the tail part of the hammer handle 5 and has the weight of 15g is taken down and then is arranged in the groove A3 in a threaded connection mode, so that the weight of the hammer head 2 is increased to 25g, and a straight key or a flat key is inserted into the concave hole 9 to assist in rotating until the movable weight 6 is completely and fixedly arranged in the groove A3. According to the scale on the movable rod 4, the using length of the drum hammer for detection is convenient to adjust. After each detection, the chalk on the side surface of the hammer head 2 can be used for marking, so that repeated detection is avoided. The utility model discloses rational in infrastructure, labour saving and time saving not only can alleviate measurement personnel knapsack weight, reduces the condition that the instrument lost and falls, can also alleviate measurement personnel's working strength, reduces the link and the step of many operations, has improved the work efficiency who detects greatly.
