Description

TECHNICAL FIELD

[0001] The utility model relates to cable laying construction technical field especially is related to a cable trench mouth Z type steel net width and flatness inspection device. BACKGROUND

[0002] During the municipal cable laying construction, the cable trench with the rectangular section is excavated and poured on the ground first, then the Z type steel (formed by the upper roof and lower bottom plate arranged horizontally and connected by the vertical connecting vertical plate) is symmetrically laid on both sides of the trench mouth, and then the cable trench cover plate is adapted and laid between the two Z type steels. The two symmetrically laid Z type steels need to ensure that the flatness is consistent in the entire length direction, and the net width between the two Z type steels should also always keep consistent with the width of the cable trench cover plate. The existing methods for detecting the net width and flatness of the cable trench Z type steel all rely on a large number of manpower to hold the level meter for segmental detection, which consumes a lot of manpower and material resources, and once the distance interval of the adjacent detection points is too long, it is easy to cause poor accuracy of the detection result, affecting the subsequent laying of the cable trench cover plate. SUMMARY

[0003] The utility model aims at the defects of prior art, provides a cable trench mouth Z type steel net width and flatness inspection device.

[0004] To achieve the above-mentioned purpose, the utility model can adopt the following technical solutions:

[0005] The cable trench mouth Z type steel net width and flatness inspection device, comprising the digital level meter that horizontal crossly arranges on the upper roof of two Z type steels, the net width measurement square steel for inspecting the interval of the connecting vertical plate of two Z type steels is attached on the bottom surface of the digital level meter, the net width measurement square steel is fixedly connected with the digital level meter through a pair of stainless steel clamps, two stainless steel clamps are connected as a whole through the horizontal connecting plate attached to the top surface thereof, the telescopic rod with the holding handle at the end is connected to the top surface center of the horizontal connecting plate through the universal ball head, a pair of walking wheels walking along the lower bottom plate of two Z type steels is arranged on the bottom surface of the net width measurement square steel.

[0006] Further, the rubber anti-skid sleeve with anti-skid convex points is also sleeved on the outer wall of the holding handle, so as to improve the comfort and friction force when the operator grips.

[0007] The utility model has the advantages of simple structure, convenient operation and low processing cost. It can be easily placed on the two Z type steels laid in the cable trench mouth, and moved along the length direction of the Z type steel, so that the net width and flatness of all points of the two Z type steels can be quickly inspected, the labor input is small, and the inspection accuracy and efficiency are greatly improved. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 is a structural schematic view of the utility model. DETAILED DESCRIPTION

[0009] The technical solutions in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0010] As Figure 1 shown, the cable trench mouth Z-shaped steel net width and flatness inspection device disclosed by the utility model comprises a digital level 1 horizontally cross-laid on the upper top plate of two Z-shaped steels 100, and the existing common Great Wall Precision GWP-LS9 digital laser level can be adopted, the digital level 1 is cross-laid on the upper top plate of two Z-shaped steels 100 along the cable trench mouth width direction, so that whether the upper top plates of two Z-shaped steels 100 are flush can be detected, and then whether two groups of Z-shaped steels 100 symmetrically laid on the cable trench mouth are consistent in height can be determined.

[0011] A net width measuring square steel 2 is attached on the bottom horizontal plane of the digital level 1, and the net width measuring square steel 2 is used for inspecting the spacing between the connecting vertical plates of two Z-shaped steels 100, and can be cut from a galvanized square steel pipe, and the cutting length is determined according to the standard net width between two Z-shaped steels to be laid at the cable trench mouth, and the net width measuring square steel 2 is fixedly connected with the digital level 1 through a pair of stainless steel clamps 3.
