Description

Technical Field

[0001] This utility model relates to the field of trench support technology, and in particular to a multifunctional construction support device. Background Technology

[0002] Construction support devices are temporary support equipment used in municipal engineering, pipeline construction, and foundation pit excavation. They are mostly used to prevent the collapse of soil on the sidewalls of pipe trenches (or trenches), ensuring the safety of construction personnel and the smooth progress of the project. Their core function is to support the trench walls and prevent soil slippage. They are suitable for underground pipeline construction for water supply and drainage, gas, electricity, communications, and oil. For example, when laying aviation fuel pipelines, which requires trench excavation, this support device can be used to support and protect the trench.

[0003] In existing technologies, commonly used construction support devices typically use pipes or steel plates welded into a cuboid support frame to support the two sides inside the trench. However, construction support devices made by welding cannot be applied to trenches of different widths, making it inconvenient to adjust the width of the construction support device according to the width of the trench. This also prevents the two sides of the construction support device from fitting well with the two sides inside the trench, resulting in poor support effect and inability to provide adequate protection. Utility Model Content

[0004] In view of this, the present invention provides a multifunctional construction support device. The main technical problem to be solved is that the construction support device made by welding in the prior art cannot adjust the width of the construction support device according to the width of the trench, resulting in poor support and protection effects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional construction support device, comprising a left guard plate and a right guard plate, wherein a left top plate is installed on the upper surface of the left guard plate, and a right top plate is installed on the upper surface of the right guard plate. The right end of the left top plate is slidably connected to the interior of the right top plate. A connecting seat five is fixedly connected to the outer wall of the right top plate. A lead screw is rotatably connected to the interior of the connecting seat five. The lead screw is rotatably connected to the interior of the right top plate and threadedly connected to the interior of the left top plate. A throttle handle is fixedly connected to the outer wall of the lead screw. A left insert block is fixedly connected to the lower surface of the left top plate, and a right insert block is fixedly connected to the lower surface of the right top plate. The left insert block is slidably connected to the interior of the left guard plate, and the right insert block is slidably connected to the interior of the right guard plate.

[0006] By adopting the above technical solution, when it is necessary to adjust the width of the construction support device according to the width of the trench, firstly, turn the throttle to drive the screw rod to rotate. During the rotation of the screw rod, the left top plate is driven to slide horizontally, causing the right end of the left top plate to slide within the right top plate. The movement of the left top plate drives the left guard plate to move, thereby adjusting the distance between the left and right guard plates, thus adjusting the width of the construction support device. This allows the outer walls of the left and right guard plates to fit against the inner sides of the trench, improving the support and protection effects of the construction support device.

[0007] As a further description of the above technical solution: a connecting seat is fixedly connected to both sides of the outer wall of the left guard plate, a threaded rod is threadedly connected to the inside of the connecting seat, a locking block is movably connected to the outer wall of the threaded rod, and the locking block is slidably connected inside the left guard plate and the left insert block.

[0008] By adopting the above technical solution, the threaded rod is limited to rotate inside the locking block. Rotating the threaded rod causes it to slide the locking block away from the inside of the left insert block. Then, the left top plate can be moved up and away from the inside of the left guard plate, thus realizing the disassembly of the left top plate and the left guard plate.

[0009] As a further description of the above technical solution: Connecting seats three are fixedly connected to both sides of the outer wall of the right guard plate, and threaded rod two is threadedly connected to the inside of the connecting seat three. A locking block two is movably connected to the outer wall of the threaded rod two, and the locking block two is slidably connected inside the right guard plate and the right insert block.

[0010] By adopting the above technical solution, the threaded rod two is limited to rotate inside the locking block two. Rotating the threaded rod two causes it to drive the locking block two to slide out of the inside of the right insert block. Then, the right top plate can be moved up and away from the inside of the right guard plate, thus realizing the disassembly of the right top plate and the right guard plate.

[0011] As a further description of the above technical solution: a slider is slidably connected to both sides of the inside of the left guard plate, and a screw is rotatably connected inside the slider.

[0012] By adopting the above technical solution, slider one is limited to sliding inside the left guard plate, and screw one is limited to rotating inside slider one.

[0013] As a further description of the above technical solution: the outer walls of the left guard plate are fixedly connected to the second connecting seat, and the screw is threaded into the inside of the second connecting seat.

[0014] By adopting the above technical solution, rotating screw one causes it to move down along connecting seat two, causing the bottom of screw one to be inserted into the trench, thus fixing and supporting the left guard plate in the trench.

[0015] As a further description of the above technical solution: the inner sides of the right guard plate are slidably connected to slider two, and the inner sides of slider two are rotatably connected to screw two.

[0016] By adopting the above technical solution, the second slider is limited to sliding inside the right guard plate, and the second screw is limited to rotating inside the second slider.

[0017] As a further description of the above technical solution: Connecting seats four are fixedly connected to both sides of the outer wall of the right guard plate, and screw two are threaded into the interior of the connecting seats four.

[0018] By adopting the above technical solution, rotating screw two causes it to move down along connecting seat four and causes the bottom of screw two to be inserted into the trench, thus fixing and supporting the right guard plate in the trench.

[0019] By means of the above technical solution, the multifunctional construction support device of this utility model has at least the following characteristics:

[0020] Beneficial effects:

[0021] 1. Compared with the existing technology, this multi-functional construction support device drives the screw rod to rotate by rotating the handle. During the rotation of the screw rod, the left top plate is moved horizontally and slidably, causing the right end of the left top plate to slide within the right top plate. The movement of the left top plate drives the left guard plate to move, thereby adjusting the distance between the left and right guard plates and adjusting the width of the construction support device. This allows the outer walls of the left and right guard plates to fit against the inner sides of the trench, improving the support and protection effects of the construction support device.

[0022] 2. Compared with the prior art, this multi-functional construction support device, by rotating two screws (screw 1 and screw 2), causes screws 1 and 2 to rotate, thereby driving sliders 1 and 2 to move downwards. The bottoms of screws 1 and 2 are inserted into the trench, fixing the left and right protective plates to the two sides inside the trench. When it is necessary to disassemble the left and right protective plates, the left and right top plates, and the right top plates, rotating threaded rod 1 causes it to slide and disengage the locking block 1 from the inside of the left insert block, and rotating threaded rod 2 causes it to slide and disengage the locking block 2 from the inside of the right insert block. Then, the left and right top plate assembly can be moved upwards, causing the left and right insert blocks to slide and disengage from the inside of the left and right protective plates, thereby achieving the effect of disassembling and separating the left and right top plates from the left and right protective plates.
