[0002] Brick inspection wells, also known as manholes, refer to various inspection wells, valve wells, meeting wells, exhaust wells, observation wells, fire-fighting wells, and various working wells used for cleaning, dredging, and maintenance that are set up for the maintenance and installation of underground infrastructure such as power supply, water supply, drainage, communications, cable TV, gas pipelines, and street lamp lines. Their function is to facilitate equipment inspection, maintenance, and installation.
[0003] However, during the implementation process, due to the uneven professional quality of workers and the lack of responsibility of some personnel, the installation position of the ladder is prone to inaccurate during the construction of the inspection well, which can be mainly divided into the following situations:
[0004] (1) The vertical and horizontal spacing varies, which is inconsistent with the size of the atlas; (2) The entire well depth was not measured in advance when laying from bottom to top, and the ladder position was not arranged in advance. When laying to the top, the remaining size was either much larger than 22 cm or less than 20 cm; (3) The top to bottom was not straight, which easily led to inaccurate installation positions of the ladders, resulting in a low qualified rate of ladder installation, which caused hidden dangers to the later delivery and acceptance. In view of the above situation, a device that can effectively improve the qualified rate of inspection well ladder installation is designed to locate the ladder installation position, which effectively improves the one-time installation qualified rate of the ladder. Therefore, a device for locating the installation position of the inspection well ladder is proposed to solve the above problems. Summary of the invention

[0021] The following will be combined with the drawings in 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0022] See also Figure 1-2 A device for locating the installation position of a ladder in an inspection well, comprising an installation device arranged in an inspection well 1 and used for locating and installing the ladder; the installation device comprises a vertical pole 2, two movable sleeves 3 detachably installed on the outside of the vertical pole 2, a height positioning cross bar 4 fixedly installed on the left and right sides of the two movable sleeves 3, a width positioning ring 7 fixedly installed on the end away from the top height positioning cross bar 4, a length measuring soft rope 6 hooked on the outside of the two width positioning rings 7, and a hook 8 fixedly installed on the other end of the length measuring soft rope 6, a fixed iron ring 9 hooked with the hook 8 is detachably installed on the outside of the vertical pole 2, and a plurality of equally spaced positioning circular rings 10 are fixedly installed on the outside of the two length measuring soft ropes 6.
[0023] The two bottom height positioning cross bars 4 are rotatably mounted with guide wheels 11 on the separated sides, and the two length measuring soft ropes 6 are in contact with the outer surfaces of the two guide wheels 11. The interior of the vertical pole 2 is provided with a plurality of rear circular holes 13 distributed at equal intervals, and the interiors of the two movable sleeves 3 are both equipped with fixing bolts 5 connected with the rear circular holes 13.
[0024] It should be noted that the bottom end of the vertical pole 2 is welded with a bottom horizontal pole 12, and the vertical pole 2 and the bottom horizontal pole 12 are in a T shape. The positioning rings 10 on the two length measuring soft ropes 6 are staggered. The first positioning ring 10 from top to bottom is 220mm, and then the left and right are vertically arranged and installed at 360mm each, until the height of 40cm at the bottom of the well.
[0025] When this embodiment is in use, the top of the upper height positioning crossbar 4 is aligned with the designed elevation, the fixing bolts 5 are tightened, and then the length measuring ropes 6 on both sides are allowed to droop naturally, and the hooks 8 at the ends of the length measuring ropes 6 are pulled to make the length measuring ropes 6 straight and tight from top to bottom, and then the hooks 8 at the ends are hung in the fixed iron rings 9 on the vertical poles 2. Finally, when laying masonry from bottom to top, the ladder is positioned and installed according to the length measuring ropes 6 on both sides of the device and the positioning rings 10 on the length measuring ropes 6. Example
[0026] See also Figure 3-4 On the basis of the first embodiment, a support structure is provided on the bottom horizontal rod 12, and the support structure includes a screw rod 14 threadedly installed inside the bottom horizontal rod 12 and extending outside thereof, a knob 15 fixedly installed at the upper and lower ends of the screw rod 14, and a support block 16. The screw rod 14 is rotated by the knob 15, and the rotation of the screw 14 drives the support block 16 to move downward, so that the bottom horizontal rod 12 is vertically placed in the inspection well 1, thereby improving the accuracy of the installation position of the ladder.
[0027] In this embodiment, the number of the supporting structures is at least two. When there are two supporting structures, the two supporting structures are symmetrically arranged. When there are three supporting structures, the three supporting structures are arranged in a triangle shape.

The device can adjust the position of the upper and lower height positioning cross bar 4 according to the height of the inspection well 1 and the sludge well. Most of the inspection wells 1 of this project are 1.5-3.0m high. When the depth of the inspection well is greater than 3m or deeper, the telescopic rod 17 in the vertical pole 2 is extended, and then the length of the length measuring soft rope 6 on both sides is changed, which is suitable for inspection wells 1 with greater depth.
[0029] The working principle of the above embodiment is:
[0030] First, before building the inspection well, make the top of the upper height positioning crossbar 4 flush with the designed elevation, tighten the fixing bolts 5, then let the length measuring ropes 6 on both sides droop naturally, and pull the hooks 8 at the ends of the length measuring ropes 6 to make the length measuring ropes 6 straight and tight from top to bottom, then hang the hooks 8 at the ends in the fixed iron rings 9 on the vertical poles 2, and finally, when building from bottom to top, position and install the ladder according to the length measuring ropes 6 on both sides of the device and the positioning rings 10 on the length measuring ropes 6.
