[0002] Inspection wells are set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage, communication, cable TV, gas pipes, street light lines, etc., and are easy to install. They are usually set up at the intersection of pipelines, bends, places where pipe diameters or slopes change, and at regular intervals on straight pipe sections to facilitate regular inspection of auxiliary structures. Cement inspection wells are generally well-shaped buildings consisting of a well seat, a well body, a well cover, and related components.

[0003] The manufacture of inspection wells mainly relies on inner mold barrels and outer mold barrels. Cement is poured between the inner and outer molds to form them. The existing inspection well shaft inner mold support structure usually uses a support structure to strengthen the inner mold barrel to ensure that it will not break when adding cement. However, the position of the support structure is mostly fixed. When the manufactured inspection well is shorter, the support structure cannot accurately support the relevant position of the inner mold barrel, which poses a safety hazard to production.

[0004] To this end, we propose an inspection well shaft inner mold support structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 , an inner mold support structure of an inspection well shaft, including an inner mold barrel 1, a cylindrical deep groove 2 is provided in the inner mold barrel 1, which is convenient for adjusting the support structure, a working pad 3 is fixedly connected in the cylindrical deep groove 2, a working screw 4 is rotatably connected to the working pad 3, a working slider 5 is threadedly connected to the working screw 4, and a working slide bar 6 is also fixedly connected to the working pad 3, the working slider 5 and the working slide bar 6 are slidably connected, the working slide bar 6 limits the working slider 5, so that the working slider 5 can only slide up and down along the direction of the working screw 4, and a plurality of strength support components 7 are provided on the working slider 5, and the strength support component 7 includes a connecting rod 8 fixedly connected to the outer wall of the working slider 5, and a working slide groove 9 is provided at one end of the connecting rod 8 away from the working slider 5, and a sliding rod 10 is slidably connected in the working slide groove 9;

[0022] The end of the sliding rod 10 away from the connecting rod 8 is fixedly connected to a support block 11, and the support block 11 can effectively provide strength support for the inner mold barrel 1. The inner mold barrel 1 is also provided with a transmission assembly, which includes a positioning plate 12 fixedly connected to the end of the cylindrical deep groove 2 away from the working pad 3, and a working motor 13 is fixedly connected to the positioning plate 12. The positioning plate 12 provides a working position for the working motor 13 to prevent the working motor 13 from falling off. A bevel gear 14 is fixedly connected to the output end of the working motor 13, and a bevel gear 2 15 is fixedly connected to the end of the working screw 4 close to the working motor 13. The bevel gear 14 and the bevel gear 2 15 are meshed, so that the working motor 13 can drive the working screw 4 to rotate through gear transmission when working;

[0023] Bolt holes are provided on the connecting rod 8 and the sliding rod 10, and locking bolts 16 are provided in the bolt holes. The locking bolts 16 and the bolt holes are matched with each other, and one end of the locking bolt 16 passes through the connecting rod 8 to prevent the support block 11 from sliding, thereby further improving the supporting effect of the support block 11. The end of the working slide rod 6 away from the working pad 3 is fixedly connected to the limiting plate 17, and the limiting plate 17 and the working slide block 5 are matched with each other to prevent the working slide block 5 from sliding too far. The sliding rod 10 and the support block 11 are detachable, which is convenient for the staff to replace the support blocks 11 of different sizes. The support block 11 and the side wall of the inner mold barrel 1 are matched with each other, and the multiple support blocks 11 are symmetrically arranged in pairs about the working slide block 5.

[0024] During the use of the utility model, the staff first installs and places the inner mold barrel 1, and then places the outer mold barrel according to the manufacturing needs, and then starts the working motor 13, so that the bevel gear 1 14 fixedly connected to the output end of the working motor 13 rotates. Due to the characteristics of gear meshing, the bevel gear 2 15 will also start to rotate, thereby driving the working screw 4 to rotate. Due to the characteristics of the threaded connection, the working slide block 5 will start to move, and the working slide bar 6 limits the working slide block 5, so that the working slide block 5 can only slide up and down along the working screw 4, thereby driving the support block 11 to move. When it moves to a position where it can provide strength support for the manufacturing of this inspection well, the staff can turn off the working motor 13;

[0025] Then cement can be added between the inner mold barrel 1 and the outer mold barrel to manufacture the inspection well. When the size of the support block 11 needs to be adjusted, the staff only needs to remove the locking bolt 16 to make the support block 11 and the sliding rod 10 slide along the working slide groove 9, and then the staff can replace the support block 11. After the replacement is completed, it is only necessary to make the support block 11 fit the inner wall of the inner mold barrel 1 and use the locking bolt 16 to fix the sliding rod 10.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
