Detailed Description
The invention will now be further described with reference to the accompanying drawings. The air pipe mounting structure is fixed on the inner wall of the civil air duct and is used for clamping and fixing the butting flange 501 butted in the air pipe 5.
As shown in fig. 1 to 4, the main design of the air duct mounting structure is as follows: the main body of the air duct mounting structure is a fixing support 1 which is formed by welding an upper channel steel and a lower channel steel into an L shape, bolt holes are formed in the side face of the fixing support, and the fixing support is convenient to lock and fix with the inner wall of a civil air duct through bolt pieces. The lower channel-section steel of fixed bolster bottom is equipped with the spacing clamp plate 2 that is the articulated setting of upset for the fixed bolster as supporting bench 101 that supports flange above the supporting bench, and spacing clamp plate one end forms the activity hinge joint through articulated shaft or hinge pin and fixed bolster promptly, and spacing clamp plate targets in place towards the upset of supporting bench direction, and when spacing clamp plate reached the spacing end A of upset promptly, spacing clamp plate and supporting bench formed the clamping state to above-mentioned docking flange 501 of docking air pipe 5. When the limiting pressure plate is turned to the other direction in place, namely the limiting pressure plate reaches the turning limiting end B, the clamping state is released, and the butt flange is in a free releasing state relative to the fixed support, namely when the butt flange enters and exits the fixed support, no interference structure exists in the entering and exiting direction.
The fixing bracket 1 is provided with a limiting pressure plate 2 which abuts against the overturning limiting end A, and the limiting pressure plate and the supporting table 101 are enabled to clamp and fix a locking piece of the butting flange 501. The locking piece specifically has two kinds of scheme structures, scheme structure one, as shown in fig. 1, fig. 2, the locking piece is platelike rotatory jam plate 3, rotatory jam plate passes through the rotatory articulated plate seat 102 that is located one side of fixed bolster upper end that is fixed through articulated bolt promptly, the one end of rotatory jam plate is plane end 302, and form fillet transition between this plane end and the rotatory jam plate side, the other end is operation rotatory jam plate pivoted operating end 301 for operating, the operating end design is long and thin structure, make things convenient for outside stock operating means to peg graft the cooperation and use. When the rotary locking plate rotates to the plane end to be close to the supporting platform and to be parallel to the supporting surface of the supporting platform, the rotary locking plate in the state supports the limiting pressing plate of the turnover limiting end A tightly to stop rotating, and the rotary locking plate forms a rotary self-locking state. When the rotary locking plate rotates to the plane end to be vertical to the supporting surface of the supporting platform, the rotary locking plate in the state releases the rotation stopping of the limiting pressure plate. Under this scheme, in order to further improve the convenience of operation and the reliability of use, can also make the following improvement design, specifically: the limiting pressing plate is located at the rotating limiting end B, when the rotating locking plate rotates to the plane end to be close to the supporting platform and to be parallel to the supporting surface of the supporting platform, the limiting pressing plate abuts against and is limited on one side, facing towards the inner wall of the civil air duct, of the rotating locking plate under the self-weight action, namely the limiting pressing plate is limited by the rotating limiting end B to be overturned to the rotating limiting end A under the state. Through the improvement, when the butt flange of the butt joint air pipe enters or is separated from the fixing support, the butt joint air pipe does not interfere with the limiting pressing plate, and the air pipe is convenient to install.
A second structure of the locking member, as shown in fig. 3 and 4, the locking member is a locking rod 4 with external threads, one end of the locking rod is a connecting end for operating the locking rod to rotate and move axially, and the connecting end is designed to be a slotted structure with an inverted T-shaped cross section as shown in the figure, but is not limited to this structure, and may be any other connecting end which facilitates the locking rod to rotate and move axially; the other end of the locking rod is a propping end. The fixing support is characterized in that a threaded hole seat 103 is arranged on one side of the upper end of the fixing support, a threaded rod section of the locking rod is in threaded connection with the threaded hole seat, a non-threaded rod section of the locking rod is in sliding fit with the threaded hole seat, and the locking rod is perpendicular to a supporting surface of the supporting table after being connected with the threaded hole seat. The thread section of the locking rod is arranged on the upper section and the abutting end of the locking rod, and the abutting end is provided with threads, so that the locking rod can be conveniently indicated or limited in place when the locking rod extends out of the thread hole seat in a sliding mode. When the locking rod is locked in place relative to the thread hole seat, the locking rod in the state supports the limiting pressure plate 2 of the turnover limiting end A to stop rotating. When the locking rod releases the threaded connection relative to the threaded hole seat and slides and extends in place relative to the threaded hole seat, the locking rod in the state releases the rotation stop of the limiting pressure plate. Under this scheme, in order to further improve the convenience of operation and the reliability of use, can also make the following improvement design, specifically: the limiting pressure plate is located at the rotating limiting end B, and when the locking rod slides towards the supporting table relative to the threaded hole seat and extends in place, the limiting pressure plate abuts against and is limited at one side, facing the inner wall of the civil air duct, of the locking rod under the self-weight action, namely the locking rod in the state limits the limiting pressure plate to be overturned to the rotating limiting end A from the rotating limiting end B. Through the structural improvement, similarly, when the butting flange of the butting air pipe enters or is separated from the fixed support, the butting flange does not interfere with the limiting pressing plate, and the installation of the butting flange of the air pipe is facilitated.
In order to prevent the limit pressing plate 2 from interfering the air pipe 5, the butt flange 501 enters or is separated from the fixed support 1, the butt joint installation operation of the air pipe is convenient, a reset torsion spring is arranged at the hinged position of the limit pressing plate, or a reset spring 6 is connected between the limit pressing plate and the fixed support, the reset torsion spring or the reset spring forms an acting force which is turned over to a turning limit end B from a turning limit end A to the turning limit end B to the limit pressing plate, when the limit pressing plate is located at the turning limit end B, the free end of the limit pressing plate is located on one side of the locking piece facing the air pipe, so that the limit pressing plate is always located.
As shown in fig. 5, in order to achieve that the limiting pressing plate 2 automatically reaches the clamping state, a reset torsion spring is arranged at the hinged position of the limiting pressing plate, or a reset spring 6 is connected between the limiting pressing plate and the fixing support, and the reset torsion spring or the reset spring forms an acting force for overturning the limiting pressing plate from the overturning limiting end B to the overturning limiting end a. Therefore, when the rotation stopping state of the locking piece on the limiting pressing plate is released, the limiting pressing plate automatically overturns to the limiting end A to realize clamping, and the operation is more convenient.
Furthermore, in order to improve the reliability and stability of the limit pressing plate 2 and the supporting table 101 for clamping the air pipe 5 butting flange 501, rubber pads are arranged on clamping surfaces used for clamping the butting flange in the supporting table and the limit pressing plate, so that the effects of skid resistance, shock absorption and abrasion resistance are achieved. In order to improve the reliability of the limit pressing plate for tightly supporting the butting flange in the air pipe, the limit pressing plate can also be designed to be an arc-shaped part or a bent part with elastic deformation, the limit pressing plate is positioned in a clamping state, and when the locking piece tightly supports the limit pressing plate, the deformation force generated by the arc-shaped part or the bent part of the limit pressing plate keeps the limit pressing plate to tightly support the butting flange.
As shown in fig. 5 to 8, the concrete installation method of the air duct installation structure in the civil engineering air duct is as follows: firstly, hoisting an air pipe 5 into a civil air duct, performing pre-positioning, then extending the support platform 101 of the fixed support 1 into the lower side of the butt flange 501 of the air pipe along the gap by utilizing the gap between the air pipe and the inner wall of the civil air duct, and supporting the butt flange. And keeping the supporting state, and locking and fixing the fixing support and the inner wall of the civil air duct through a bolt piece to finish the installation of the fixing support. A plurality of fixing supports are arranged along the circumferential direction of the inner wall of the civil air duct in an array mode, and the air duct is reliably supported. Next, the limiting pressing plates 2 of the fixing supports are turned to the proper positions towards the inner wall side of the civil air duct, namely, turned to the turning limiting ends B, and the rotating locking plates 3 are rotated to enable the limiting pressing plates to abut against the rotating locking plates to face towards the inner wall side of the civil air duct, namely, the limiting pressing plates are kept at the turning limiting ends B. After the operation is finished, another air pipe is hoisted into the civil air duct, so that the butt flange at the lower end of the air pipe is in butt joint with the butt flange at the upper end of the air pipe. After the butt joint, through outside stock handling tool, peg graft stock handling tool and the operation end 301 of rotatory jam plate to rotate rotatory jam plate and remove spacing to spacing clamp plate, spacing clamp plate deadweight effect down the upset to offset with the flange, spacing clamp plate and the flange of a supporting bench centre gripping two tuber pipes promptly. And finally, rotating the rotary locking plate through a long rod operating tool to enable the plane end of the rotary locking plate to abut against the surface of the limiting pressing plate in a clamping state, enabling the rotary locking plate to reach a rotary self-locking state, and enabling the limiting pressing plate and the supporting platform to complete clamping and fixing of the abutting flanges of the two air pipes, namely completing abutting installation of the air pipes in the civil engineering air duct.
