Description

  The present invention relates to an inspection device used for inspecting from the surface side whether or not mortar, tile, concrete or the like forming a wall portion of a structure has peeling, deterioration, expansion, or contamination.

  Conventionally, if peeling, deterioration, expansion, air / foreign matter contamination, etc. occur on mortars or tiles that are attached to or pasted on the wall of a building, the site where the peeling occurs will fall and cause an accident. Therefore, regular inspections are made. As an inspection method, a lifting gondola is hung from the roof of a building, and an operator riding on the lifting gondola hits an inspection hammer to determine the presence or absence of a part such as mortar peeling from the reflected sound. Such a method is generally called a percussion method.

  For this general percussion method, the present applicant previously proposed an inspection tool such as a structure (Patent Document 1). Such an inspection tool is provided with a rolling element that is rotatably supported by the tip support shaft portion of the operating rod, and the operator holds the operating rod in his hand and presses the rolling element against the surface of the structure, etc. Then, by swinging or moving the operating rod left and right, back and forth, or up and down, it is a loud striking sound that is generated when the rolling element rolls. Can be determined.

A cord 24 connected to a power source 40 extends from the drive motor 22. As a result, the rotational driving force from the drive motor 22 is decelerated via the speed reduction mechanism 23 and transmitted to the rotation shaft 16a of the head portion 16 to rotate each rolling portion 10 at a low speed.

  The case body 21 has a compact outer dimension, and a support member 25 is fixed to the lower surface thereof. The support member 25 is fixed to the upper end of the uppermost step portion 30A of the telescopic rod 30. As a result, the driving device 20 is placed on the upper end of the uppermost step portion 30 </ b> A of the telescopic rod 30 via the support member 25.

  As shown in FIGS. 8 and 9, the inspection device S <b> 2 includes a plurality (four in the illustrated example) of the rolling unit 10, the driving device 50, a hanging strap 60 as a support means, and a power source 70. I have. Each rolling part 10 includes a support shaft 11 attached around the head part 16 and a rolling element 12 supported rotatably at the tip of the support shaft 12, as in the inspection device S1. As the head portion 16 rotates, the rolling element 12 at the tip of each support shaft 11 continuously rolls on the wall surface 1 of the structure. The head unit 16 is rotatably supported at the tip of the driving device 50.

  The drive device 50 includes a case body 51, a drive motor 52 built in the case body 51, and a speed reduction mechanism 53 built in the case body 51. The rotational driving force of the drive motor 52 is transmitted from the worm gear 52 a to the speed reduction mechanism 53, and further transmitted from the speed reduction mechanism 53 to the rotation shaft 16 a of the head portion 16. A cord 54 connected to the power source 70 extends from the drive motor 52. As a result, the rotational driving force from the drive motor 52 is decelerated via the speed reduction mechanism 53 and transmitted to the rotary shaft 16a of the head portion 16, thereby rotating the rolling portions 10 at a low speed. A string suspending portion 55 is provided on the upper surface of the case body 51. The string suspending portion 55 includes a fixing plate 55a fixed to the upper surface of the case body 51 and a hook 55b locked to the fixing plate 55a. A lower end hook 60a of the hanging string 60 is attached to the hook 55b. It is adapted to be hooked through a spring 61. The cord 54 can be handled integrally by being wound around the hanging strap 60 in the middle.

  An attachment member 81 is provided on the front surface of the case body 51, and stabilization bars 82, 82 protruding from the front surface of the case body 51 to the left and right sides are attached to the attachment member 81. Each stabilizing bar 82 serves to stably bring the rolling element 12 into contact with the wall surface 1 of the structure T, extends parallel to the left and right from the mounting member 81, and bends from the middle to the tip. A bent portion 82a that gradually approaches the wall surface 1 as it goes is formed. The ends of the left and right bent portions 82a are bent downward to form support portions 82b. A guide roller 83 in close contact with the wall surface 1 of the structure T is rotatably supported by each support portion 82b. By the action of the left and right guide rollers 83 and 83 and the stabilization bars 82 and 82, the rolling element 12 in front of the head portion 16 can be stably brought into contact with the wall surface 1 of the structure T.

  A rotating fan attachment plate 85 is attached to the back surface of the case body 51 via left and right attachment members 84. The rotating fan mounting plate 85 is provided with an opening 85a, and the fan case body 86a containing the rotating fan 86 is located on the back surface of the rotating fan mounting plate 85 so that the rotating fan 86 is positioned in the opening 85a. It is attached. The rotational driving force from the drive motor 52 of FIG. 9 is transmitted to the rotational shaft 86b of the rotational fan 86. Then, by the rotational drive of the rotary fan 86, an air flow F is formed from the inner side of the rotary fan mounting plate 85, that is, from the wall surface 1 side of the structure T to the outer side of the rotary fan mounting plate 85. The inner side of the head has a negative pressure tendency, and serves to stably bring the rolling element 12 in front of the head portion 16 into contact with the wall surface 1 of the structure T.

  Wind pressure plates 87 and 87 are attached to both side surfaces of the rotary fan attachment plate 85. As shown in FIG. 10, the wind pressure plates 87 and 87 are provided so as to be bent so as to approach the wall surface 1 of the structure T as they move away from the rotating fan mounting plate 85 in the left-right direction. As a result, the wind pressure W from the lateral direction is received by the wind pressure plate 87 and serves to stably abut the rolling element 12 in front of the head portion 16 against the wall surface 1 of the structure T.

  FIG. 11 shows a state where the wall surface 1 of the structure T is being inspected from the roof using the inspection device S2. Depending on the height of the structure T, the inspection device S1 of FIG. In such a case, the inspection device S2 is slowly lowered from the roof 2 of the structure T by the hanging strap 60, and gradually moves from below while swinging the inspection device S2 to the left and right according to the pendulum as shown in FIG. Check while moving up. At the time of inspection, a switch (not shown) at hand is turned on and the drive motor 52 is driven to rotate. As a result, the rolling element 12 is moved at a low speed around the rotation shaft 16a of the head portion 16 on the front surface of the drive device 50, and at the same time, the rotary fan 86. Rotate.

  As the rotary fan 86 rotates, the inside of the rotary fan mounting plate 85 tends to have a negative pressure, and each rolling element 12 is appropriately pressed against the wall surface 1 of the structure T by the wind pressure. Due to the stabilizing action of the left and right guide rollers 83 and the stabilizing bar 82, each rolling element 12 is stably brought into contact with the wall surface 1 of the structure T. In such a stable contact state, each rolling element 12 rolls around the rotating shaft 16a of the head portion 16 at a low speed, so that the rolling noise generated from each rolling element 12 causes peeling at the inspection location. Can be clearly identified and checked.

  In addition, when there is a crosswind, the driving device 50 suspended by the suspension string 60 receives the wind pressure W of the crosswind and swings left and right or back and forth, and the contact posture and contact state of each rolling element 12 are inspected. Although it is assumed that it becomes unstable, by providing the wind pressure plates 87, 87, it can be used as means for stabilizing the wind pressure W from the cross wind. Here, the stability bar 82, the guide roller 83, the rotary fan 86, and the wind pressure plate 87 described above stabilize the position of the driving device 50 with respect to the wall surface 1 at the time of inspection, and always stabilize the rolling by the rolling element 12. Constituting the means for generating.

  When the rolling element 12 is rolled, the operator does not shake or move the hand holding the hanging strap 60 left and right or up and down, so the load on the operator can be greatly reduced compared to the conventional case. In addition, by constantly generating a stable rolling sound by the stabilizing means described above, it is possible to perform inspection work efficiently and over a wide range.

  By inspecting the wall surface 1 quickly and stably, the inspection device S2 suspended by the suspension strap 60 is swung left and right by the pendulum method. That is, by swinging the inspection device S2 to the left and right in the manner of a pendulum, the inspection device S2 being inspected by each rolling element 12 (inspection range A) can be smoothly moved to the left and right. Since the inspection device S2 is constantly stably pressed against the wall surface 1 by the wind pressure of the rotary fan 87, the moving speed of the inspection device S2 can be increased to increase the efficiency of the inspection work.

  As described above, the inspection device of the present invention reduces mortar, tiles, etc. over a wide range from a low position to a high place of a structure while reducing the burden on the operator. -It can be checked for deterioration and expansion, and is extremely convenient. Also, the structure is simple and can be manufactured at a low manufacturing cost.

  The inspection device according to the present invention can be widely used as an inspection device for inspecting the presence or absence of delamination / deterioration / expansion / contamination of foreign matter in mortar, tile, concrete, etc. that forms the walls of structures. is there.
