However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0021] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] In this utility model, such as Figures 1 to 2 As shown, a manhole step installation device is provided, including a rigid main rod 1, with positioning plates 2 on both sides of the main rod 1, and positioning holes 3 spaced laterally on the positioning plates 2, and the positioning plates 2 are configured as elastic plates.

[0025] When using the step installation device of this utility model, the operator places the rod close to the wall of the inspection well, and the positioning plate 2 is in contact with the wall of the inspection well. At this time, by determining the position of the main rod 1, the position of the positioning hole 3 on the positioning plate 2 can be obtained, and the operator can conveniently use a marker to mark the position of the step using the positioning hole 3.

[0026] The step installation device of this utility model, by setting positioning plates 2 on both sides of the main rod 1, can simultaneously mark the positions of multiple steps after positioning the main rod 1 once. Furthermore, by employing an elastic plate, this utility model can adapt to changes in the curvature of the well wall through deformation, thereby improving its applicability.

[0027] In a preferred embodiment, more specifically, the main rod 1 is configured as a metal tube.

[0028] In a preferred embodiment, more specifically regarding the structure of this utility model, the positioning plate 2 is rotatably connected to the main rod 1 by rivets 4, so that the positioning plate 2 can rotate in the positioning position and the folded position. When the positioning plate 2 is in the positioning position, the axis of the positioning plate 2 is approximately perpendicular to the axis of the main rod 1. When the positioning plate 2 is in the folded position, the angle between the axis of the positioning plate 2 and the axis of the main rod 1 is less than or equal to 15°.

[0029] With this configuration, the positioning plate 2 can be rotated to a folded position when the installation device of this utility model is not used, so as to facilitate carrying and storage, and also reduce the risk of the positioning plate 2 being accidentally damaged.

[0030] It should be noted that the term "approximately perpendicular" in this utility model refers to the ideal state in which the axis of the main rod 1 and the axis of the positioning plate 2 are perpendicular. However, due to processing and assembly errors, the perpendicularity between the axis of the main rod 1 and the axis of the positioning plate 2 can have a certain error within an allowable range. This error is preferably controlled within 3°.

[0031] The axis referred to here is the geometric center line of the main rod 1 and the geometric center line of the positioning plate 2.

[0032] In a preferred embodiment, more specifically regarding the structure of this utility model, the main rod 1 is provided with an upward-facing positioning notch 6, and when the positioning plate 2 is in the positioning position, the positioning plate 2 can be positioned and inserted into the positioning notch 6.

[0033] As shown in the figure, by setting the positioning notch 6, the positioning plate 2 can be stably stopped in the positioning position, so as to further maintain the stability of the positioning plate 2 in the positioning position.

[0034] When it is necessary to fold the positioning plate 2, as shown in the figure, the positioning plate 2 can be rotated upward to make the positioning plate 2 rotate out of the positioning notch 6. At this time, the positioning plate 2 can be rotated upward to fold, or the positioning plate 2 can be rotated downward to make the positioning plate 2 deviate outward and deform around the edge of the positioning notch 6 before folding.

[0035] In a preferred embodiment, more specifically regarding the structure of this utility model, a fixing plate 5 is provided on the adjacent side of the main rod 1 and the positioning plate 2. The fixing plate 5 extends partially out of the side of the main rod 1, and the portion of the fixing plate 5 extending out of the main rod 1 is provided with a positioning notch 6.

[0036] As shown in the figure, the fixing plate 5 is roughly L-shaped, and the part of the fixing plate 5 that extends out of the main rod 1 forms a positioning notch 6 between it and the rod body.

[0037] In a preferred embodiment, more specifically regarding the structure of this utility model, the positioning hole is configured as an oblong hole, and the mounting device further includes an adhesive cloth.

[0038] By setting the positioning holes to be oblong, the oblong holes can be partially covered with adhesive cloth to adjust the relative positions between the marking points, so as to accommodate the positional shifts caused by changes in the curvature of the elastic plate.

[0039] In a preferred embodiment, specifically regarding the structure of this utility model, the lower and upper sections of the main rod 1 are respectively provided with marking holes 7 at vertical intervals. As shown in the figure, on one side of the main rod 1, two nuts are welded to the upper and lower sections of the main rod 1, respectively. The inner holes of the nuts form marking holes 7. By setting the marking holes 7, when marking the step points in the lower area, the marking holes 7 on the upper section of the main rod 1 are marked. When the main rod 1 is moved upward to the upper area, the marking holes 7 at the lower section of the main rod 1 correspond to the existing markings, thereby facilitating the positioning of the main rod 1.

[0040] In a preferred embodiment, specifically regarding the structure of this utility model, a handle 8 is provided in the middle section of the main rod 1. As shown in the figure, this facilitates operation by the operator.

[0041] In a preferred embodiment, more specifically regarding the structure of this utility model, at least one side of the main rod 1 is provided with multiple positioning plates 2 along the vertical direction. As shown in the figure, the right side of the main rod 1 is provided with two positioning plates 2 and the left side is provided with one positioning plate 2, thereby enabling the marking of multiple step positions at one time.

[0042] In a preferred embodiment, specifically regarding the structure of this invention, the installation device further includes a binding rope. By providing the binding rope, the positioning plate 2 and the main rod 1 can be bound and fixed together when the positioning plate 2 is in the folded position.
