Technical Field

[0001] The utility model relates to the technical field of highway detection equipment, in particular to a highway detection core drill Background Technique

[0002] A highway detection core drill is a device used to extract cylindrical specimens from concrete structures such as highway pavements or bridges. This device is usually used to evaluate the quality and strength of concrete, as well as to determine whether there are internal defects or damages. The main components of a highway detection core drill include a support frame, a lifting mechanism, a drill, a rotary bit, a water pump, and a water tank, etc. The rotary bit is usually made of cemented carbide or diamond and can rotate at high speed and cut the concrete surface.

[0003] During the use of a traditional highway detection core drill, although wheels are installed on the support frame to assist the movement of the core drill, after arriving at the destination, it is still necessary to manually turn the wheels upward (the purpose of turning the wheels is to separate the wheels from the road surface so that the support frame can stably support on the road surface), thereby reducing the convenience of the highway detection core drill during use.

[0004] Therefore, this application specifically proposes a highway detection core drill to solve the above technical problems. Content of the Utility Model

[0005] The main purpose of the utility model is to solve the above deficiencies and provide a highway detection core drill that does not require manual upward turning of the wheels, improving the convenience during use.

[0031] Embodiment 2, on the basis of Embodiment 1, as Figure 1 、 Figure 5 and Figure 6 shown:

[0032] A transparent window 501 is inlaid inside the right end face of the water tank 5, and an audible and visual alarm 502 is installed on the front side of the right end face of the water tank 5; four vertical guide rods 503 are arranged inside the water tank 5, and a sliding plate 504 is slidably connected to the outside of the four vertical guide rods 503; a floating block 505 is arranged at the bottom of the sliding plate 504; two vertical sliding rods 506 are arranged on the upper end face of the sliding plate 504, the two vertical sliding rods 506 penetrate through the top of the water tank 5, and the upper ends of the two vertical sliding rods 506 are fixedly connected with a pressing plate; a pressing switch 507 is installed below the pressing plate at the top of the water tank 5; when the distance between the bottom end face of the floating block 505 and the inner bottom end face of the water tank 5 accounts for one-fifth of the inner height of the water tank 5, the pressing plate presses the button on the pressing switch 507;

[0033] Through the cooperation of the vertical guide rods 503, the sliding plate 504, the floating block 505, the vertical sliding rods 506, the pressing switch 507 and the pressing plate, when the distance between the bottom end face of the floating block 505 and the inner bottom end face of the water tank 5 accounts for one-fifth of the inner height of the water tank 5, the pressing plate presses the button on the pressing switch 507, thereby starting the audible and visual alarm 502, bringing an effective warning effect to the staff, and thus being able to replenish water into the water tank 5 in time.

[0034] The working principle of this embodiment: During use, when it is necessary to move, first, the controller 104 controls the telescopic rod of the electric push rod 704 to extend downward, thereby driving the lifting plate member 701, the universal wheels 703 and the two directional wheels 702 to move downward in a straight line, so that the universal wheels 703 and the two directional wheels 702 are in contact with the road surface, and then the road surface detection coring machine is moved to the road surface to be monitored through the universal wheels 703 and the two directional wheels 702;

[0035] After reaching the destination, the controller 104 is used to control the telescopic rod of the electric push rod 704 to retract upward, thereby driving the lifting plate member 701, the universal wheels 703 and the two directional wheels 702 to move upward in a straight line, so that the universal wheels 703 and the two directional wheels 702 are separated from the road surface. At this time, the bottom end face of the base 1 is in contact with the road surface, and then the drilling and detection work can be carried out.

[0036] Then, the diesel engine 3 is started, so that the diesel engine 3 drives the input shafts of the drill shaft 401, the drill bit 402 and the water pump 403 to rotate, thereby generating suction at the water suction port of the water pump 403, so as to transport the water source inside the water tank 5 to the outside of the drill bit 402. Then, the controller 104 controls the rotation of the shaft of the drive motor 201, thereby driving the drive screw 202 to rotate. Then, the lifting plate 203 moves leftward in a straight line under the action of the thread, and then the drilling mechanism 4 drills the road surface through the drill bit 402.

[0037] During the drilling process, the water source inside the water tank 5 will be continuously consumed, causing the floating block 505 floating on the water surface to slowly descend, thereby driving the sliding plate 504, the two vertical sliding rods 506, and the pressing plate to move downward. When the distance between the bottom end surface of the floating block 505 and the inner bottom end surface of the water tank 5 accounts for one-fifth of the inner height of the water tank 5, the pressing plate presses the button on the pressure switch 507, thereby activating the sound and light alarm 502, bringing an effective warning to the staff, and enabling the timely replenishment of water into the water tank 5.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.

[0039] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
