Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a hole-drilling tool for measuring the carbonation depth value of concrete. Background Technique

[0002] The rebound method is a commonly used technique for detecting the compressive strength of concrete. When measuring the rebound value of concrete with a rebound hammer, it is necessary to measure the carbonation depth value at the same time. To measure the carbonation depth, an auxiliary tool is required to chisel out a hole about 15 mm deep on the concrete surface.

[0003] In the prior art, when chiseling holes in the wall surface, most commonly used unprofessional auxiliary tools such as hammers, drill bits, steel wire heads, etc. are used for chiseling, and then tools such as ear bulbs are used to clean the powder and debris in the holes, and then the carbonation depth value is measured. A large number of auxiliary tools need to be carried, which is not convenient for the detection work. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hole-drilling tool for measuring the carbonation depth value of concrete to solve the above-mentioned deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

The axial two ends of the hammer head are respectively provided with a first receiving groove and a second receiving groove; a connecting rod capable of sliding axially along the hammer head is arranged in the first receiving groove; one axial end of the connecting rod is fixedly connected with a first rubber block, and the inner wall of the first receiving groove is fixedly connected with a second rubber block coaxially and in contact connection with the first rubber block; one axial end of the connecting rod is also connected with a support rod. A limiting groove is arranged on the inner wall of the first receiving groove. One axial end of the support rod is fixedly connected with the connecting rod, and the other axial end of the support rod extends into the limiting groove and is fixedly connected with a limiting block adapted to the limiting groove; the other axial end of the connecting rod is fixedly connected with a conical chisel; a blowing structure is arranged in the second receiving groove.

[0007] Further, the hammer head is perpendicular to and fixedly connected with the hammer handle. A reinforcing rib is arranged at the connection between the hammer head and the hammer handle, and anti-slip lines are arranged on the surface of the hammer handle.

[0008] Further, the blowing structure includes an airbag arranged in the second receiving groove and a pressing block fixedly connected to the outer surface of the airbag. One axial end of the airbag is communicated with the outside of the hammer head through a blowing pipe, and the pressing end of the pressing block extends to the outside of the hammer head.

[0009] Further, through holes for the pressing block and the blowing pipe to extend out are respectively arranged on the surface of the hammer head.

[0010] Furthermore, a chute is axially formed on the inner side surface of the first receiving groove, and a slider capable of being embedded in the chute is arranged on the outer surface of the connecting rod.

[0011] As can be seen from the above technical solutions, the utility model adopts an overall structural design of a hammer head and a hammer handle, and a conical chisel and an airbag are arranged at the hammer head, integrating the functions of hole drilling and dust removal, saving time and effort while meeting the hole drilling depth, and facilitating the subsequent detection work.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following is a detailed description of a preferred embodiment of the utility model with reference to the drawings.

[0017] As Figure 1 and 2 shown, the hole drilling tool for measuring the concrete carbonation depth value includes a hammer head 1 and a hammer handle 2. The first receiving groove 3 and the second receiving groove 4 are respectively formed at the two axial ends of the hammer head 1, integrating the functions of hole drilling and dust removal, reducing the tools carried by the staff, and saving time and effort.

[0018] Specifically, a connecting rod 5 capable of sliding axially along the hammer head 1 is arranged in the first receiving groove 3 of this preferred embodiment. One axial end of the connecting rod 5 is fixedly connected with a conical chisel 6. A chute is axially formed on the inner side surface of the first receiving groove 3. A slider capable of being embedded in the chute is arranged on the outer surface of the connecting rod 5. Further, a first rubber block 7 is fixedly connected to the other axial end of the connecting rod 5. A second rubber block 8 coaxially and in contact connection with the first rubber block 7 is fixedly connected to the inner wall of the first receiving groove 3. Two support rods 9 are also connected to one axial end of the connecting rod 5. A limiting groove 10 is formed on the inner wall of the first receiving groove 3. One axial end of the support rod 9 is fixedly connected with the connecting rod 5. The other axial end of the support rod 9 extends into the limiting groove 10 and is fixedly connected with a limiting block 11 adapted to the limiting groove.

[0019] In specific use, after the staff holds the hammer handle 2, the conical chisel 6 can be used to collide with the wall surface to drill holes. During the knocking process, the connecting rod 5 squeezes the first rubber block 7 and the second rubber block 8 to generate elastic force, buffering the vibration generated by the knocking and protecting the staff's hands. After the connecting rod 5 is squeezed to a certain distance, the limiting block 11 abuts against the inner wall of the limiting groove 10, and then the connecting rod 5 can be supported, improving the stability of the conical chisel 6 to break through the wall surface.

[0020] A blowing structure is arranged in the second receiving groove 4 of this preferred embodiment. Specifically, the blowing structure includes an airbag 12 arranged in the second receiving groove 4 and a pressing block 13 fixedly connected to the outer surface of the airbag 12. One axial end of the airbag 12 is communicated with the outside of the hammer head 1 through a blow pipe 14. The pressing end of the pressing block 13 extends to the outside of the hammer head 1. Further, through holes for the pressing block 13, the blow pipe 14 to extend out are respectively formed on the surface of the hammer head 1.

[0021] In specific use, after the drilling is completed, by pressing the pressing block 13 to squeeze the airbag 12 to deform, and then discharging the air flow through the blow pipe 14, the dust inside the drilled groove can be blown out, facilitating subsequent detection.

[0022] The hammer head 1 and the hammer handle 2 of this preferred embodiment are perpendicular and fixedly connected. A reinforcing rib is arranged at the connection of the hammer head and the hammer handle to improve strength and stiffness, making the overall structure more solid and durable. Anti-slip patterns are formed on the surface of the hammer handle to ensure that the hammer handle can be firmly held during use.

[0023] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
