Problems solved by technology

[0003] Since the bottom of the detection head of the wall crack detector for construction engineering supervision is relatively flat, and there is usually fine powder attached to the wall of the construction site, the fine powder will adhere to the detection head when the detection head is pressed and attached to the building wall. At the bottom of the head, after the detection head is used for many times, the fine powder attached to the bottom continues to accumulate, and it takes time to clean the powder manually, otherwise it will affect the detection accuracy of cracks in the wall

Embodiment 1

[0028] For example figure 1 -example Figure 6 Shown:

[0029] The invention provides a detection device for construction engineering supervision, its structure includes a detection head 1, a controller 2, a wire 3, the left end of the wire 3 is embedded and connected to the upper end of the controller 2, the upper end of the detection head 1 is connected to the The right end of the wire 3 is connected; the detection head 1 includes a frame body 11, a telescopic block 12, an elastic sheet 13, and an elastic bar 14, the upper end of the frame body 11 is connected with the right end of the wire 3, and the telescopic block 12 is connected with the The inner wall of the frame body 11 is movably engaged, the elastic sheet 13 is installed between the telescopic block 12 and the bottom of the frame body 11 , and the elastic bar 14 is installed between the telescopic block 12 and the upper end of the inner wall of the frame body 11 .

[0030] Wherein, the telescopic block 12 include...

Embodiment 2

[0037] For example Figure 7 -example Figure 9 Shown:

[0038] Wherein, the support frame a1 includes a contraction block d1, a reset bar d2, and an outer frame d3, the inner wall of the outer frame d3 is slidably matched with the sliding rod a4, and the upper end of the inner wall of the outer frame d3 is connected with the rebound piece a3, so The shrinkage block d1 is slidably matched with the inside of the outer frame d3, and the reset bar d2 is installed between the upper end of the inner wall of the outer frame d3 and the shrinkage block d1. The shrinkage block d1 has a circular structure, thereby reducing the contact with the wall The contact area is large, so it can avoid a large amount of dust on the wall from adhering to its surface.

[0039] Wherein, the shrinkage block d1 includes a bonding surface d11, a center block d12, and a ring body d13, the center block d12 is connected to the bottom of the reset bar d2, and the center block d12 is engaged with the inner ...

Abstract

The invention discloses a detection device for constructional engineering supervision. The structure of the detection device comprises a detection head, a control instrument and a conducting wire, wherein the left end of the conducting wire is fixedly connected with the upper end of the control instrument in an embedded mode, and the upper end of the detection head is connected with the right end of the conducting wire. According to the invention, when the detection head leaves the surface of a building wall, an elastic strip pushes a sliding rod to rapidly reset downwards along a frame body, and a movable block can generate impact vibration on the inner wall of a plate surface under the cooperation of an inner connecting cavity, so that powder at the bottom of the plate surface can be vibrated off; a contraction block can slide and contract upwards along an outer frame through reverse thrust generated by the surface of the building wall on the contraction block, so that the supporting frame can be attached to the surface of the building wall, and a large amount of fine powder cannot be attached to the bottom of the supporting frame; and the contraction block can be pushed through a reset strip to slide downwards to be rapidly reset when the reverse thrust of the building wall is lost, so that the fine powder attached to the contraction block can be vibrated off.

Description

technical field [0001] The invention relates to the field of construction engineering supervision, in particular to a detection device for construction engineering supervision. Background technique [0002] The wall crack detector for construction engineering supervision is mainly used for crack detection of building walls. By attaching the detection head on the wall crack detector for construction engineering supervision to the wall, the detection head can be Detect the internal cracks of the wall, and then display the data through the display screen on the controller. Based on the above description, the inventor found that the existing detection device for construction supervision mainly has the following deficiencies, for example: [0003] Since the bottom of the detection head of the wall crack detector for construction engineering supervision is relatively flat, and there is usually fine powder attached to the wall of the construction site, the fine powder will adhere t...
