Description

Technical Field

[0001] The invention relates to a building component, in particular to a pipe trench movable lintel device. Background Art

[0002] Lintels are widely used in industrial and civil buildings. Their function is to support various loads from objects above the opening and transfer these loads to the walls on both sides of the opening. Pipe trench lintels are mostly set at the intersection of pipe trenches to support the upper cover plate and operating loads of the intersection.

[0003] After the lintels are set at the intersections of the trenches, the trench covers can use uniform specifications without having to adjust the cover size according to the intersection position.

[0004] There are generally two types of fixed trench lintels. When the trench width is large, a reinforced concrete structure is used. When the trench width is small, a simple angle steel can be used. For specific methods, please refer to "Trench and Cover Plate" (New 12G08). During pipeline installation and maintenance, the fixed trench lintel limits the operating space of the pipeline, and it is impossible to assemble the pipeline as a whole or in part and put it into or remove it from the trench at the same time, which affects the construction and maintenance efficiency.

[0005] When some covers are opened to inspect pipelines on a steep slope, other trench covers may slip due to the vibration of the plant units, causing accidents such as cover slippage and falling, damaging the covers and even causing safety accidents. Summary of the invention

[0006] The present invention aims to overcome the defects existing in the above-mentioned prior art and provide a movable lintel device for a pipe trench, which can not only simplify the design and manufacturing process of the pipe trench cover, but also can flexibly rotate without affecting the installation and maintenance of the pipeline, and can also prevent the cover plate on the slope from sliding toward the air side.

[0007] The technical solution adopted by the present invention is:

[0008] A movable lintel device for a pipe trench comprises an anchor plate, a support plate, a rotating shaft, an inclined support plate, a hollow lintel, a baffle, a locking plate, a locking groove, a locking rod and a permanent magnet, wherein the anchor plate is provided with an anchor foot, which is buried in the side wall of the pipe trench and is used to fix the support plate; the support plate is fixed to the anchor plate, and a circular hole is provided on the support plate for passing and supporting the rotating shaft; the rotating shaft is fixed to the inclined support plate and the hollow lintel, and the three can rotate 90 degrees around the holes on the support plate, but cannot move in parallel; the inclined support plate is used to support the hollow lintel and strengthen the fixed connection between the rotating shaft and the hollow lintel; the hollow lintel is used to support the upper cover plate of the pipe trench, and can be rotated to the side wall of the pipe when the pipe is being repaired, so as to facilitate the repair of the pipe; the baffle is provided on the upper part of the hollow lintel, and a circular hole is provided inside The locking plate has a strip hole on the side; the baffle is fixed on the upper part of the hollow lintel and is at the same height as the upper cover plate of the pipe trench. It can rotate together with the hollow lintel to prevent the cover plate from sliding along the direction of the pipe trench; the locking plate is provided with a handle, which extends from the strip hole on the side of the hollow lintel, and the locking plate can be moved parallel to the inside of the hollow lintel through the handle; the locking groove is buried in the side wall of the pipe trench on the opposite side of the anchor plate, and is used to insert the locking plate and support the hollow lintel; the permanent magnet is buried in the side wall of the pipe trench on the same side of the anchor plate, and is used to fix the hollow lintel in the open state, so that the device is in the open state; the locking rod can be thrown into the locking holes of the hollow lintel and the locking plate when the locking plate is inserted into the locking groove, so that the device is in the locked state, and the locking rod can be placed freely and separately when pulled out.

[0009] In the locked state, the hollow lintel and the baffle are perpendicular to the direction of the trench, the locking plate is inserted into the locking groove, and the locking rod is invested in the locking holes of the hollow lintel and the locking plate, so that the hollow lintel is in a locked and closed state. This device supports and prevents the trench cover from slipping.

[0010] When in the open state, the locking rod is pulled out from the locking holes of the hollow lintel and the locking plate, the locking plate is disengaged from the locking groove, the hollow lintel and the baffle are rotated to be parallel to the direction of the pipe trench, and the permanent magnet attracts the hollow lintel to prevent the device from rotating at will.

[0011] The beneficial effects of the present invention are as follows: the pipe trench lintel of the present invention is provided with a locking device, which, in the locked state, supports the upper cover plate and load of the pipe trench, avoids the appearance of irregular cover plates at the intersection of the pipe trenches, and simplifies the production and transportation. On a pipe trench with a large slope, the lintel device is arranged at a certain interval to limit the slippage of the cover plate. The pipe trench lintel of the present invention can be rotated and fixed. When the pipeline needs to be repaired, the lintel device is unlocked and rotated to the side wall of the pipe trench and fixed, which can provide conditions for the overall repair of the pipeline.
