DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown, this embodiment discloses a cantilever measuring device for measuring slope, including a trolley frame 1, a rectangular guide cylinder 7 and a rectangular scale rod 11.

[0022] The bottom of the trolley frame 1 is provided with four universal rollers 2 and four leveling feet 3, and the trolley frame 1 is provided with a cargo box 5, and the cargo box 5 is provided with an openable box cover 6. The rectangular guide cylinder 7 is detachably connected to the top of the box cover 6, and the rectangular guide cylinder 7 is provided with a winding wheel 8, and the winding wheel 8 is wound with a steel strand 9, and the free end of the steel strand 9 is provided with a hanging cone 10; the rectangular scale rod 11 is slidably connected in the rectangular guide cylinder 7, and the front end of the rectangular scale rod 11 is provided with a detachable pulley 12, and the rectangular scale rod 11 includes a plurality of rod bodies 1101 that are sequentially terminated and detachably connected, and the outer wall of each rod body 1101 is provided with scales.

[0023] In this embodiment, one side of the box cover 6 is rotatably connected to the cargo box 5 via a hinge, and the other side is detachably connected to the cargo box 5 via a buckle 4.

[0024] In this embodiment, a horizontal bubble meter 13 is provided on the rectangular guide cylinder 7 .

[0025] In this embodiment, a plug 1102 is provided at one end of the rod body 1101, and a slot 1103 is provided at the other end. The plugs 1102 of two adjacent rod bodies 1101 are plugged into and matched with the slots 1103; a countersunk hole 1104 is provided on the outer surface of the rod body 1101 at a position corresponding to the slot 1103, and a threaded hole 1105 is opened on the outer wall of the plug 1102, and the countersunk hole 1104 is fixed to the threaded hole 1105 by a countersunk bolt.

[0026] In this embodiment, a plurality of rings 901 are provided on the steel strand 9, and scales are provided on the outer walls of the rings 901.

[0027] The use process of the utility model is as follows:

[0028] When not in use, the rectangular scale rod 11 can be disassembled into a plurality of rod bodies 1101 and the rectangular guide cylinder 7 can be disassembled from the box cover 6, and then the whole can be placed in the cargo box 5 for storage and transportation.

[0029] When in use, the rectangular guide cylinder 7 is fixed to the box cover 6 by bolts, and then a plurality of rod bodies 1101 are assembled into a scale rod 11 according to the use requirements, and the pulley 12 is installed at the front end of the scale rod 11, and the wheel frame on the pulley 12 is fixed to the scale rod 11 by bolts. When measuring, the scale rod 11 is moved forward or backward in the rectangular guide cylinder 7, and the steel strand 9 is released at the same time, and finally the hanging cone 10 is vertical to the intersection of the foundation pit ground and the slope surface, and the scale of the scale rod 11 corresponding to the top of the slope and the length of the steel strand 9 released are read. The length of the steel strand 9 released minus the extended length of the scale rod 11 and the height of the trolley frame 1 and the cargo box 5 is the height of the slope, and the extended length of the scale rod 11 is the width of the slope. Finally, the slope rate is calculated according to the trigonometric function.

[0030] It should be noted that a common length, height, and corresponding slope rate query table can be prepared in the cargo box 5, so that personnel can quickly query.

[0031] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
