Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a hollowing detection device. Background Art

[0002] Construction refers to the whole process of building various types of buildings from scratch at a predetermined location after the building design is completed, according to the design drawings, technical specifications and relevant laws and regulations. The existing hollow drum detection device drives the detection module to move through the driving rod, and during the movement, the hollow drum hammer is driven by the rotation of the roller to continuously hit to achieve hollow drum detection. However, in actual use, due to the relatively simple structure of the driving hollow drum hammer, the hitting force of the hollow drum hammer is uneven, which affects the hollow drum detection.

[0003] For example, the utility model with announcement number CN219201458U discloses a device for detecting hollow drums in facing bricks, including a push rod, a side surface of the push rod being rotatably connected to a rotating shaft, a side surface of the rotating shaft being fixedly connected to a connecting rod, an end of the connecting rod away from the rotating shaft being fixedly connected to a roller, and the left and right ends of the rotating shaft are fixedly sleeved with striking wheels, the lower end of the push rod is fixedly connected to an assembly plate, a knocking rod is movably inserted into the top surface of the assembly plate, the upper end of the knocking rod is slidingly connected to the side surface of the striking wheel, and a spring is arranged between the knocking rod and the assembly plate. In the technical solution of this patent, the rotation of the roller drives the striking wheels on the left and right sides to rotate, and then the striking wheel drives the knocking rod at the lower end to continuously rise and fall to perform striking detection. However, only the spring and the striking wheel drive the knocking rod to descend and reset, and this structure is prone to wear, which makes the striking force of the hollow drum hammer uneven, affecting the hollow drum detection. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a hollow drum detection device. By making the detection hammer continuously reciprocate up and down under the drive of the running wheels during the movement of the detection box, hollow drum detection can be performed quickly and efficiently.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a hollow drum detection device, including a detection box, two support plates symmetrically distributed front and back are arranged on the left and right sides of the detection box, a rotating shaft is rotatably arranged between the two adjacent support plates on the left and right, and running wheels are fixedly sleeved on the left and right ends of the outer arc surface of the rotating shaft, and a hollow drum detection module for hollow drum detection is also arranged on the detection box; a rotating frame is rotatably arranged on the upper side of the detection box, a telescopic rod is arranged in the middle of the upper surface of the rotating frame, and an armrest is arranged at the end of the telescopic rod away from the rotating frame; anti-slip sponge sleeves are arranged on the left and right sides of the armrest.

[0006] As a further improvement of the utility model, the hollow drum detection module includes a movable frame slidably arranged on the lower side of the interior of the detection box, a detection hammer is arranged in the middle of the lower surface of the movable frame, a driving unit for driving the detection hammer to move is also arranged on the detection box, and a buffer unit for buffering the detection hammer is also arranged on the movable frame; the buffer unit includes a buffer spring arranged between the movable frame and the inner bottom end of the detection box.

[0007] As a further improvement of the utility model, the driving unit includes a rotating disk symmetrically arranged on the inner walls of the left and right sides of the detection box and rotating through a rotating axis, a driving rod is respectively rotatably arranged between the two adjacent rotating disks on the left and right, a driving groove is opened at the upper end of the movable frame, and the driving rods are installed in cooperation with the driving groove, and a synchronous pulley two is fixedly sleeved on the left and right sides of the outer arc surface of the rotating shaft, and a synchronous pulley one is fixedly sleeved on the outer arc surface of the rotating shaft, and the synchronous pulley one is respectively connected to the vertically adjacent synchronous pulley two through a transmission synchronous belt.

[0008] As a further improvement of the utility model, a buffer rubber sleeve is bonded and fixed to the outer side surface of the lower end of the detection hammer.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, hold the handrail to push the test box to move, and the four running wheels on the lower side of the test box can quickly and smoothly push the test box for mobile testing.

[0011] Secondly, during the movement of the detection box, the traveling wheels drive the rotating shaft connected thereto to rotate. During the movement of the detection box, the detection hammer is driven by the traveling wheels to continuously reciprocate up and down, so that hollow drum detection can be performed quickly and efficiently.

[0012] Thirdly, the synchronous pulleys 2 on the left and right sides of the outer arc surface of the rotating shaft rotate, and the transmission relationship between the synchronous pulleys 2 and 1 drives the four synchronous pulleys 1 to rotate synchronously. The circular motion of the driving rods on the front and rear sides cooperates with the driving groove on the upper side of the movable frame to drive the movable frame to slide continuously with the detection box, so that the movable frame drives the detection hammer at its lower end to perform fast and stable up and down reciprocating motion.

[0013] Fourthly, the outer side of the detection hammer can be buffered by the buffer rubber sleeve, and the cooperation of the buffer rubber sleeve and the buffer spring can effectively extend the service life of the detection hammer and prevent the detection hammer from being easily deformed.
