Technical Field
[0001] The utility model relates to the technical field of engineering quality acceptance, and more particularly to an engineering quality acceptance device. Background Art
[0002] Engineering quality acceptance is a process of evaluating the quality and achievements of engineering construction. It occurs after the completion of the project and is carried out according to relevant industry standards. This process consists of three main links: the self-inspection and acceptance link of the construction team, the completion acceptance link of the project department, and the sampling inspection and acceptance link of the company. The purpose of engineering quality acceptance is to ensure that the engineering quality meets the specified standards, guarantee the safety and durability of the project, and at the same time, it is also a recognition of the work achievements of the construction unit;
[0003] Currently, when accepting the walls of a building project, a hollowing hammer is usually used to strike the building wall to detect whether there is a hollowing phenomenon. At this time, the acceptance personnel need to hold the hollowing hammer in one hand for inspection and acceptance, and hold a marker pen in the other hand to mark the hollowing area. However, it is difficult for the acceptance personnel to mark the hollowing at a higher position on the wall surface, and the acceptance personnel need to hold the marker pen in real time for marking, which is not conducive to the acceptance work of the acceptance personnel using the hollowing hammer and needs to be improved. Summary of the Utility Model
[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an engineering quality acceptance device to solve the problems existing in the above background art.

[0021] Embodiment 1:
[0022] As Figures 1-5 shown, an engineering quality acceptance device includes a hollow drum hammer 1. The hollow drum hammer 1 includes a hammer rod 11 and a hammer head 12. A threaded connection groove 121 is formed at the bottom of the hammer head 12. The top end of the hammer rod 11 is threadedly connected inside the threaded connection groove 121. A bolt 122 is threadedly connected inside the hammer head 12, and the bottom end of the bolt 122 is threadedly connected inside the top end of the hammer rod 11.
[0023] In this embodiment, when the hammer rod 11 or the hammer head 12 is damaged after long-term use, first screw off the bolt 122, and then rotate the hammer rod 11 or the hammer head 12 in a spiral manner so that the top end of the hammer rod 11 is taken out from the threaded connection groove 121 at the bottom of the hammer head 12, thereby realizing the separation of the hammer rod 11 and the hammer head 12, and facilitating the replacement of the hammer rod 11 or the hammer head 12.
[0024] Embodiment 2:
[0025] As Figures 1-5As shown in the figure, a hollow drum marking mechanism 3 is provided on the left side of the hammer head 12. The hollow drum marking mechanism 3 includes an installation cover 33. The right side of the installation cover 33 is fixedly connected to the left side of the hammer head 12. A marking pen 31 is provided inside the installation cover 33. The marking end of the marking pen 31 extends to the left side of the installation cover 33. An arc-shaped clamping plate 36 is provided above the inside of the installation cover 33. The middle part of the top of the installation cover 33 is threadedly connected with a screw rod 35. The top end of the screw rod 35 is fixedly connected with a knob 34. The bottom end of the screw rod 35 is rotatably connected to the middle part of the top of the arc-shaped clamping plate 36. A limiting groove 32 is opened in the middle of the left side of the hammer head 12. The other end of the marking pen 31 is inserted into the inside of the limiting groove 32. The arc-shaped clamping plate 36 is located above the marking pen 31. Two guide rods 37 are symmetrically and movably sleeved on the top of the installation cover 33. The bottom ends of the two guide rods 37 are fixedly connected to both sides of the top of the arc-shaped clamping plate 36. The bottom of the inner wall of the installation cover 33 is fixedly connected with an arc-shaped anti-slip pad 38. The lower part of the outer wall of the marking pen 31 is lapped inside the arc-shaped anti-slip pad 38.
[0026] In this embodiment, through the setting of the limiting groove 32, it is convenient to limit one end of the marking pen 31. Through the cooperation of the knob 34 and the screw rod 35, it is convenient for the acceptance personnel to adjust the position of the arc-shaped clamping plate 36. By using the setting of the two guide rods 37, vertical guidance is carried out on the arc-shaped clamping plate 36, and the inner wall of the arc-shaped clamping plate 36 can be pressed down above the marking pen 31, so as to clamp and fix the outer wall of the marking pen 31 between the arc-shaped clamping plate 36 and the arc-shaped anti-slip pad 38 inside the installation cover 33. The inner wall of the arc-shaped anti-slip pad 38 is provided with anti-slip lines, so as to increase the anti-slip property between the bottom of the marking pen 31 and the inner wall of the arc-shaped anti-slip pad 38.
[0027] Embodiment Three:
[0028] As Figures 1-5 shown, a marking pen storage cylinder 4 is fixedly connected to the left side of the hammer rod 11. An anti-slip leather sleeve 2 is fixedly sleeved on the bottom end of the outer wall of the hammer rod 11. The top end of the inner cavity of the marking pen storage cylinder 4 is threadedly sleeved with a cylinder cover 5.
[0029] In this embodiment, after the acceptance work is completed, the marking pen 31 can be taken out from the inside of the installation cover 33, and the marking pen 31 is placed inside the marking pen storage cylinder 4, and then the cylinder cover 5 is spirally installed at the top end of the inner cavity of the marking pen storage cylinder 4, so as to facilitate the storage of the marking pen 31 after acceptance and prevent the marking pen 31 from being lost when not in use.
[0030] In summary, as Figures 1-5As shown in the figure, for this engineering quality acceptance device, during use, first insert one end of the marking pen 31 through the mounting cover 33 into the internal limiting groove 32 on one side of the hammer head 12, and make the lower part of the marking pen 31 overlap inside the arc-shaped anti-slip pad 38. At this time, rotate the knob 34 and the screw rod 35, so that the bottom end of the screw rod 35 rotates on the top of the arc-shaped clamping plate 36, and pushes the arc-shaped clamping plate 36 and the guide rod 37 to move downward, pressing the inner wall of the arc-shaped clamping plate 36 above the marking pen 31, thereby clamping and fixing the marking pen 31 inside the mounting cover 33. Then, the acceptance personnel hold the anti-slip leather sleeve 2 on the outer wall of the hammer rod 11 to control the hammer head 12 and perform a hollowing detection on the wall of the construction project. For example, when the acceptance personnel use the hollowing hammer 1 to detect the hollowing of the wall, they only need to flip the hollowing hammer 1 and align the marking pen 31 on one side of the hammer head 12 with the hollowing part for marking. When the acceptance work is completed, the knob 34 and the screw rod 35 can be rotated in the reverse direction, driving the arc-shaped clamping plate 36 to move upward, so that the arc-shaped clamping plate 36 is separated from above the marking pen 31. Then, one end of the marking pen 31 is removed from the internal limiting groove 32 and the mounting cover 33. Unscrew the cylinder cover 5 in a spiral manner, place the marking pen 31 in the marking pen storage cylinder 4, and then screw the cylinder cover 5 onto the top end of the marking pen storage cylinder 4 to store and protect the marking pen 31.
