Description

Hole cutting device for concrete carbonization depth detection

Technical Field

The utility model relates to the technical field of concrete carbonization depth detection, in particular to a hole cutting device for concrete carbonization depth detection.

Background

The method aims to correct the measured value of the strength of the concrete detected by a rebound method and estimate the corrosion condition of the steel bars in the concrete. In recent years, manual hole drilling is mostly adopted for detecting the concrete carbonization depth, so that the holding performance of the cutting depth is small, the operation strength is difficult to control, and the accuracy of the detection result of the concrete carbonization depth is influenced.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical problems, the utility model provides a hole cutting device for detecting the concrete carbonization depth, which aims at solving the problems that the existing manual hole cutting mode is adopted, so that the holding performance of the cutting depth is small, the operation force is difficult to control, and the accuracy of the detection result of the concrete carbonization depth is influenced.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a hole excavation device for concrete carbonization degree of depth detects, includes the bullet drill bit, the cooperation of bullet drill bit is installed at bullet pole front end, bullet pole rear end corresponds with the trigger end that sets up the striking mechanism in the shell and is connected.

The impact drill bit is in threaded connection with the impact rod.

Striking mechanism including set up in central guide arm in the shell, slidable installs the impact hammer on the central guide arm, central guide arm front end with the impact pole rear end is corresponding, the extension spring is hit to central guide arm front end suit, the extension spring is hit to the bullet one end with central guide arm front end reciprocal anchorage, the extension spring other end is hit to the bullet with the impact hammer reciprocal anchorage.

The rear end of the central guide rod is connected with the pressure spring in a matching way through a bearing plate.

The utility model has the beneficial effects that: according to the utility model, the impact mechanism is utilized to transmit the impact force from the impact rod to the tip of the impact drill bit, so that the impact force acts on the surface of the concrete measuring area, a hole for detecting the concrete carbonization depth is formed on the surface of the concrete measuring area, and the uniformity and accuracy of the stress of the concrete measuring area when the impact drill bit drills are ensured. Furthermore, in order to make the installation and disassembly of the impact drill bit and the impact rod more convenient and facilitate the replacement of the impact drill bit, the impact drill bit and the impact rod are connected by screw threads. As a preferred technical scheme, the striking mechanism is including setting up the central guide arm in the shell, slidable installs the impact hammer on the central guide arm, because the impact hammer is connected with central guide arm front end through the impact extension spring, simultaneously, central guide arm front end corresponds with the impact pole rear end again, therefore, when pulling the impact hammer backward, the impact extension spring can produce elastic deformation, after the operator loosens the impact hammer, the impact hammer can be owing to the effect of impact extension spring, slide to central guide arm front end fast and strike at the impact pole rear end, the impact pole rear end transmits elastic impact power to the impact drill bit point portion, make the impact power act on the surface of concrete survey district, form the hole that is used for detecting concrete carbonization degree of depth on the surface of concrete survey district. Furthermore, in order to counteract the vibration generated by the sliding and impacting of the impact hammer on the central guide rod, and simultaneously, in order to enable the front end of the central guide rod to be in relatively corresponding contact with the rear end of the impact rod more stably and tightly, the rear end of the central guide rod is in fit connection with the pressure spring through the bearing plate. The method can effectively avoid the phenomena of poor accuracy, uneven drilling force and the like of manual drilling, is simple to operate, labor-saving, convenient and quick, greatly improves the accuracy and efficiency of concrete carbonization depth detection work, and has good practicability and economy.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1, a hole cutting device for detecting concrete carbonization depth comprises an impact drill bit 1, wherein the impact drill bit 1 is installed at the front end of an impact rod 2 in a matching manner, and the rear end of the impact rod 2 is correspondingly connected with a trigger end of an impact mechanism arranged in a shell 7.

As shown in fig. 1, the tapping drill 1 is screwed to the tapping rod 2.

As shown in fig. 1, the impact mechanism includes a central guide rod 5 disposed in a housing 7, a striking hammer 4 is slidably mounted on the central guide rod 5, a front end of the central guide rod 5 corresponds to a rear end of the striking rod 2, a striking extension spring 3 is sleeved at a front end of the central guide rod 5, one end of the striking extension spring 3 is fixed to a front end of the central guide rod 5, and the other end of the striking extension spring 3 is fixed to the striking hammer 4, wherein the central guide rod 5 is connected to the striking hammer 4 in a cylindrical manner, the striking hammer 4 is axially provided with a central hole, and the striking hammer 4 is sleeved on the central guide rod 5 through the central hole, so that the sliding of the striking hammer 4 on the central guide rod 5 is realized.

As shown in fig. 1, the rear end of the center guide rod 5 is connected with the compression spring 6 through a bearing plate.

When the device is used, the tip of the impact drill bit 1 is propped against the surface of a concrete measuring area, an operator holds the impact hammer 4 to pull the impact hammer 4 towards the rear end of the central guide rod 5 and then releases the impact hammer 4, the impact hammer 4 can move forwards and quickly on the central guide rod 5 under the action of the impact tension spring 3 and finally impacts the rear end of the impact rod 2, the impact rod 2 transmits the impact force to the tip of the impact drill bit 1, so that the impact force acts on the surface of the concrete measuring area, and a hole with the diameter of about 15mm for detecting the concrete carbonization depth is formed on the surface of the concrete measuring area, so that the carbonization depth of the concrete can be further detected, and the uniformity and the accuracy of the stress of the concrete measuring area during impact drilling and chiseling are ensured.
