Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a rotatable and adjustable spacing bracket arm device for an integrated pipe gallery. Background Art

[0002] In today's municipal engineering, underground integrated pipe corridors are the future development trend. The supports and arms in the pipe corridors are the core components to play the function of pipeline operation and maintenance in the pipe corridors. The traditional mode: using fixed anchor bolts or pre-buried support arm systems, they need to be laid along the wall line, and are restricted in angle and plane position. After entering the corridor, many pipelines need to turn at a certain angle or even vertically due to pipeline cross-branching or later planning access and maintenance. In particular, the turning angle requirements of first-class power grid cables entering the corridor are too strictly controlled. The current pipe corridor support arm system is difficult to meet the various requirements of pipeline operation and maintenance. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a rotatable and adjustable spacing bracket arm device for an integrated pipe gallery, so as to overcome the deficiencies in the above-mentioned prior art.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A rotating and adjustable spacing bracket support arm device for an integrated pipe gallery comprises: a column, wherein the upper and lower ends of the column are respectively provided with a movable component and a base, the movable component is connected to the upper embedded part by an upper screw, and the base is connected to the lower embedded part by a lower screw, and at least one cross arm is sleeved on the column and can be independently adjusted up and down and rotated thereon.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the upright column is made of a round steel tube, and the cross arm includes a hoop and a support arm distributed in the transverse direction and one end of which is fixed to one of the hoop plates of the hoop, and the hoop is sleeved on the upright column.

[0008] Based on the above, further beneficial effects are as follows: when there are other requirements for the pipeline entering the corridor, and the direction or height position of the cross arm is required to be partially adjusted, the bolts in the clamp are loosened, and the staff can adjust the direction and height of the clamp and the support arm. After the adjustment is in place, the bolts in the clamp are tightened to partially adjust the direction or height position of the cross arm, which is very convenient and has good stability.

[0009] Furthermore, the lower embedded part includes: a lower embedded plate and a plurality of lower embedded steel bars arranged below the lower embedded plate and fixed thereto, a lower connecting plate is fixed above the lower embedded plate, a plurality of lower threaded holes distributed in a circular manner are provided on the lower surface of the lower connecting plate, a plurality of lower arc-shaped holes distributed in a circular manner are provided between the upper and lower surfaces of the base, and the rod end of the lower screw passes through the lower arc hole and is screwed into the lower threaded hole to fix the lower connecting plate to the base.

[0010] Furthermore, the lower embedded steel bars and the lower embedded plate are connected by perforation plug welding, the lower embedded steel bars are φ16 threaded bars, the length of the lower embedded steel bars is 70mm less than the thickness of the bottom plate, and the bent anchor length is 350mm.

[0011] Furthermore, the movable component includes: a top seat distributed laterally and a sleeve fixed at the bottom of the top seat, the upper end of the column enters the sleeve through the lower end port of the sleeve, and the top seat is connected to the upper embedded part with upper screws.

[0012] Furthermore, the inner diameter of the sleeve is 5 mm to 10 mm larger than the outer diameter of the column, and the height of the sleeve is 10 cm to 15 cm.

[0013] Furthermore, the upper embedded part includes: an upper embedded plate and a plurality of upper embedded steel bars arranged above the upper embedded plate and fixed thereto, an upper connecting plate is fixed below the upper embedded plate, a plurality of upper threaded holes distributed in a circular manner are provided on the lower surface of the upper connecting plate, a plurality of upper arc-shaped holes distributed in a circular manner are provided between the upper and lower surfaces of the top seat, and the rod end of the upper screw passes through the upper arc hole and is screwed into the upper threaded hole to fix the upper connecting plate to the top seat.

[0014] Furthermore, the upper embedded steel bars and the upper embedded plate are connected by perforation plug welding, the upper embedded steel bars are φ16 threaded bars, the length of the upper embedded steel bars is 70mm less than the thickness of the top plate, and the bent anchor length is 350mm.

[0015] Furthermore, a rotating handle is fixedly provided on the column.

[0016] The beneficial effects of the utility model are:

[0017] 1) When the linear shape of the pipe gallery structure cannot achieve a certain angle turn or adjust the up and down position along with the pipeline, compared with the traditional mode: using fixed anchor bolts or embedded bracket arm system, both need to be laid along the wall linear shape, and are restricted in angle and plane position. After entering the corridor, many pipelines need to turn at a certain angle or even vertically due to pipeline cross-branching or later planning access and maintenance. In particular, the current first-class power grid corridor cable turning angle requirements are too strictly controlled. In this integrated pipe gallery rotating adjustable spacing bracket arm device, since each cross arm on the column can be adjusted up and down and rotated independently, the cross arm can be used to adjust up and down and rotate to meet the turning requirements of the pipeline entering the corridor, and can also meet the temporary installation requirements of the pipeline during maintenance, so that the device can be used for the branch port or turning angle requirements of the pipeline in the cabin and for temporary adjustment of the pipeline during later maintenance, thereby maximizing the use function of the cross arm and saving the cost of later operation and maintenance and the direction and position of the device. The implementation process is simple and fast, and does not affect the construction of the main structure.

[0018] 2) The entire device is flexible to implement. When there are branch openings or pipeline turning requirements, several upper embedded parts can be pre-embedded on the bottom plate and several lower embedded parts can be pre-embedded on the top plate according to the needs. The movable components and columns can be installed later, and the columns can be disassembled at any time. The number of columns can be increased or decreased when meeting space and functional requirements. The movable components are connected to the upper embedded parts with upper screws, and the base is connected to the lower embedded parts with lower screws, making disassembly and assembly very convenient;

[0019] 3) In the present invention, a lower arc-shaped hole is provided on the base, and the rod end of the lower screw is passed through the lower arc-shaped hole and then screwed into the lower threaded hole to fix the lower connecting plate to the base. By loosening the lower screw, the staff can manually rotate the column within a small range to adjust the angle of the cross arm on the column. After the adjustment is in place, the lower screw can be tightened. In other words, this solution can achieve fine adjustment of the cross arm angle;

[0020] 4) High work efficiency, simple construction, safe and reliable, precise and controllable. BRIEF DESCRIPTION OF THE DRAWINGS
