Description

Technical Field

[0001] The utility model relates to the technical field of inspection well ladder construction, in particular to a positioning device for installing an assembled inspection well ladder. Background Art

[0002] In recent years, with the development of science and technology, new building materials and processes have emerged and have been promoted in the engineering field to replace traditional building materials. As a new type of structure for drainage engineering, precast concrete assembled inspection wells have successfully replaced traditional brick inspection wells and are widely used in urban road rainwater and sewage drainage systems, playing a positive role in promoting the optimization and transformation of road drainage systems. However, most precast concrete assembled inspection wells do not have pre-buried holes for ladders during the production process, and can only be manually positioned and drilled later. During the installation process, it is generally necessary to use infrared positioning, ink fountain marking, tape measurement, engraving and marking and other auxiliary work to complete the work. Because the on-site inspection well space is small and it is necessary to climb up and down for construction, the closer to the wellhead, the more difficult it is to operate, which is time-consuming and labor-intensive. It is difficult to accurately position, resulting in uneven layout up and down and left and right. Therefore, it is necessary to develop a device that can quickly locate the installation position of the ladder to facilitate construction.

[0003] Patent publication number CN217782290U discloses a manhole ladder positioning device, comprising a first set of rods and two L-shaped rods. One end of each L-shaped rod is connected to the ends of the first set of rods, and the other end is provided with a second set of rods. Both ends of the second set of rods are provided with positioning rods, and the ends of the positioning rods away from the second set of rods are provided with positioning portions. The L-shaped rods are rotatably connected to the first set of rods, or the positioning rods are rotatably connected to the second set of rods. This manhole ladder positioning device has a simple structure, is easy to carry, and is convenient to operate. It can quickly locate the installation position of the ladder.

[0004] The above technical solution solves the problems mentioned in the background technology to a certain extent, but the above technical solution adopts rotary connection and threaded connection, which is not firm and will affect the accuracy of the positioning device after a long period of use. Moreover, the above technical solution can only locate the horizontal spacing of the ladder positioning holes, and cannot locate the vertical spacing of the ladder positioning holes.
