DETAILED DESCRIPTION

[0031] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] like Figure 1-10 As shown, the utility model provides a thin-walled cavity multi-curved plain concrete arch steel mesh positioning inspection tool, comprising:

[0033] Two symmetrically arranged support plates 1;

[0034] The support rods 2 are vertically arranged on the top of the support plate 1, and the tops of the two support rods 2 are fixedly connected with the top plate 3;

[0035] A plurality of positioning rod assemblies 4, with adjustable lengths, are vertically inserted into the support rod 2;

[0036] The lower positioning assembly 5 is detachably arranged at the bottom of the support rod 2 .

[0037] like Figure 7-10 As shown, when in use, first hang the tooling as a whole on the outside of the arch steel mesh, and adjust the insertion depth of the support rod 2 and the positioning rod assembly 4 on the lower positioning assembly 5 according to the theoretical external dimensions of the steel mesh at the position of the tooling on the design drawing, so that the ends of the positioning rods 42 of each positioning rod assembly 4 form a plane, and the shape of the plane is the same as the theoretical shape of the steel mesh at the cross section, and then judge whether the steel mesh is accurately positioned by observing whether the adjusted positioning rods 42 abut against the steel mesh.

[0038] In one embodiment, the support rod 2 is composed of two symmetrically arranged slide rails 6, a gap is provided between the two slide rails 6, a limiting groove 7 is provided on the slide rails 6, one of the slide rails 6 is provided with a long strip-shaped limiting hole 8, the tops of the two slide rails 6 are fixedly connected to the top plate 3, and the bottoms of the two slide rails 6 are fixedly connected to the support plate 1. With this design, the positioning rod assembly 4 can slide on the support rod 2, and the height of the positioning rod assembly 4 can be adjusted accordingly according to the size of the steel mesh.

[0039] In one embodiment, the outer surface of the slide rail 6 is provided with a length scale. When adjusting the height of the positioning rod assembly 4, the adjustment can be made according to the length scale on the slide rail 6.

[0040] In one embodiment, the positioning rod assembly 4 includes a slider 41 slidably set in the gap between the two slide rails 6, a positioning rod 42 vertically inserted in the slider 41, a first positioning member 43 set on the slider 41 for positioning the depth of the positioning rod 42 inserted into the slider 41, and a second positioning member 44 set on the slider 41 for positioning the height of the slider 41 on the support rod 2. A length scale is set on the positioning rod 42, and limit blocks 45 cooperating with the limit grooves 7 are set on both sides of the slider 41. With this design, the cooperation between the limit block 45 and the limit groove 7 allows the slider 41 to slide in a limited direction between the two slide rails 6 in the vertical direction, thereby adjusting the height of the positioning rod 42 inserted in the slider 41, and locking the slider 41 through the second positioning piece 44 to fix the height of the positioning rod 42; the positioning rod 42 inserted in the slider 41 can be manually adjusted in insertion length, and the length scale on the positioning rod 42 is used as a basis for adjusting the insertion length. After the adjustment is completed, the relative position of the positioning rod 42 on the slider 41 is locked by the first positioning piece 43 to prevent the positioning rod 42 and the slider 41 from sliding relative to each other during use, thereby affecting the accuracy of the detection.

[0041] In one embodiment, the first positioning member 43 includes a threaded through hole 431 formed on the slider 41 and connected to the insertion hole of the positioning rod 42, and a hand screw 432 disposed in the threaded through hole 431. With this design, when the hand screw 432 is tightened to be screwed into the threaded through hole 431, the hand screw 432 presses against the positioning rod 42, making it difficult for the positioning rod 42 to slide relative to the slider 41.

[0042] In one embodiment, the second positioning member 44 includes a positioning bolt 441 with one end fixedly arranged on the slider 41 and the other end extending through the limiting hole 8 to the outside of the slide rail 6, and a hand-tightening nut 442 arranged on the portion of the positioning bolt 441 extending out of the slide rail 6. With such a design, the hand-tightening nut 442 is tightened to make the hand-tightening nut 442 abut against the outer wall of the slide rail 6, thereby driving the slider 41 and the limiting block 45 to abut against the inner wall of the slide rail 6, increasing the friction between the slider 41 and the limiting block 45 and the slide rail 6, thereby achieving positioning.

[0043] In one embodiment, the lower positioning assembly 5 includes a cross bar 51 vertically arranged between two support rods 2, a connecting assembly 52 fixedly arranged at both ends of the cross bar 51 for detachable connection with the support rods 2, and a positioning rod assembly 4 with adjustable length vertically inserted in the cross bar 51.

[0044] like Figure 7-10As shown, when it is necessary to perform a positioning check on the suspended part of the steel mesh, the bottom surface of the steel mesh also needs to be arranged with a positioning rod assembly 4 for corresponding positioning checks. When the tooling is hung as a whole on the outside of the steel mesh and only the positioning accuracy of both sides of the steel mesh needs to be checked, the lower positioning assembly 5 is removed from the support rod 2; when it is necessary to check the suspended part of the steel mesh, the lower positioning assembly 5 is installed on the support rod 2 again, so the connection between the lower positioning assembly 5 needs to be detachable. The cross bar 51 has the same structure as the support rod 2, only the installation position is different, and both provide a sliding track and an installation bracket for the positioning rod assembly 4, so it will not be repeated here.

[0045] In one embodiment, the connecting assembly 52 includes an L-shaped positioning plate 521 fixedly arranged at both ends of the crossbar 51, a bracket 522 fixedly arranged on the L-shaped positioning plate 521, an adjustment bolt 523 passing through the bracket 522, and a pressing block 524 fixedly arranged at one end of the adjustment bolt 523. With this design, by tightening the adjustment bolt 523, the pressing block 524 moves away from the bracket 522 and presses against the outer wall of the support rod 2, thereby achieving a fixing effect and facilitating disassembly.

[0046] In one embodiment, the bottom of the support plate 1 is symmetrically provided with height-adjustable feet 9, and the top of the support plate 1 is fixedly provided with a level meter 10. When the bottom surface contacted by the support plate 1 is uneven, the height of the feet 9 is adjusted, and the level meter 10 is observed while adjusting until the support plate 1 is in a horizontal state to ensure the accuracy of the detection result.

[0047] In one embodiment, a lifting lug 11 is fixedly provided on the top of the top plate 3 .

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
