Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a construction prompting device for building engineering. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.

[0003] A search revealed an existing patent (CN216586266U) that discloses a construction prompting device for municipal engineering, comprising a support box. Two first cylinders are fixedly connected to the bottom of the support box's inner cavity on both sides. A sliding plate is fixedly connected to the top of the first cylinders. Fixed plates are fixedly connected to both sides of the top of the sliding plate. A second cylinder is fixedly connected to one side of the top of the fixed plate's inner cavity. A sliding rod is fixedly connected to the bottom of the second cylinder. An inclined plate is slidably connected to one side of the sliding rod. A sliding plate is fixedly connected to one side of the inclined plate. A support block is fixedly connected to the center of one side of the sliding plate. A limit pad is fixedly connected to one side of the support block, extending through to the outside of the fixed plate. The sliding... A warning rod is fixedly connected to the center of the top of the board. The top of the warning rod extends through to the outside of the support box and is fixedly connected to a fixing rod. A warning plate is fixedly connected to the right side of the fixing rod. This utility model adds a first cylinder and a sliding plate to the original mechanical parts to facilitate the adjustment of the height of the warning device and prevent insufficient height from delaying the construction progress. By adding a second cylinder, sliding rod, inclined plate, sliding plate, support block, spring and limiting pad, a stabilizing effect can be achieved to prevent the warning device from shaking due to wind force during operation, which would reduce the working efficiency of the warning device. At the same time, it solves the problem of poor stability of existing construction warning devices.

[0004] However, in the above solution, the prompt board provides prompts from only one side, which cannot meet the requirement of providing comprehensive information about all four sides in open areas. If multi-directional prompts are desired, the equipment needs to be turned or multiple devices need to be used in combination, which is quite troublesome.

[0005] In view of this, the present invention proposes a construction prompting device for building engineering. Summary of the Invention

[0006] This utility model proposes a construction prompting device for building engineering, which solves the problem that the prompting boards in related technologies only provide prompts from one side and cannot meet the requirement of providing comprehensive information about the surroundings in open areas. If multi-directional prompts are desired, the equipment needs to be turned or multiple devices need to be used in combination, which is quite troublesome.

[0007] The technical solution of this utility model is as follows: A construction prompting device for building engineering includes a limiting base plate; a lifting support cylinder is fixedly connected to the top of the limiting base plate; a lifting support rod is inserted into the interior of the lifting support cylinder; a first rhomboid support plate is fixedly connected to the top of the lifting support rod; two first rhomboid support plates are provided, the two first rhomboid support plates are far apart from each other; a first support column is fixedly connected to both ends of the two first rhomboid support plates; an LED curved display screen is fixedly connected between the upper and lower two first rhomboid support plates; a connecting column is fixedly connected to the top of the first rhomboid support plate; a second rhomboid support plate is fixedly connected to the top of the connecting column; the first rhomboid support plate and the second rhomboid support plate are arranged crosswise on the top view; two second rhomboid support plates are provided. The two second rhomboid support plates are spaced far apart, and two second support columns are fixedly connected to both ends of each second rhomboid support plate. LED curved display screens are fixedly connected between the upper and lower two second rhomboid support plates. Both LED curved display screens are curved screens. A warning light is fixedly connected to the top of each second rhomboid support plate. A lifting limit mechanism is provided between the inside of the lifting support rod and the lifting support cylinder. A fixed seat mechanism is fixedly connected to the bottom of the limit base plate. The LED curved display screens can display information from all four sides of the road. The LED curved display screens can also divert wind force from all four sides, reducing the impact of wind on the LED curved display screens and minimizing damage to the device.

[0008] Preferably, the lifting and limiting mechanism includes: an insert plate, a U-shaped limiting slot, a lifting support plate, and a pneumatic telescopic rod. The insert plate is fixedly connected to the bottom of the outer surface of the lifting support rod, and the U-shaped limiting slot is fixedly connected to the inner wall of the lifting support cylinder. The insert plate slides inside the U-shaped limiting slot. The bottom of the lifting support rod is fixedly connected to the lifting support plate. A pneumatic telescopic rod is provided between the bottom of the lifting support plate and the bottom of the inner opening of the lifting support cylinder. Both ends of the pneumatic telescopic rod are hinged to the lifting support plate and the lifting support cylinder, and the two ends of the pneumatic telescopic rod are rotatably connected to the lifting support plate and the lifting support cylinder through the hinges. The lifting support plate slides against the inner wall of the lifting support cylinder. The insert plate and the U-shaped limiting slot can be used to vertically position and lift the lifting support rod. When the pneumatic telescopic rod is activated to push the lifting support plate upward, the insert plate slides inside the U-shaped limiting slot, thereby allowing the lifting support rod to slide inside the lifting support cylinder.

[0009] Preferably, the number of insert plates is four, and the four insert plates are equidistantly distributed on the outside of the lifting support rod. The number of U-shaped limiting slots is four, and the four U-shaped limiting slots are equidistantly distributed on the inside of the lifting support cylinder.

[0010] Preferably, a cross-shaped pre-embedded base is fixedly connected to the bottom of the limiting base plate. Both the limiting base plate and the cross-shaped pre-embedded base have a cross-shaped structure in the top view. The fixing seat mechanism is fixed to the bottom of the limiting base plate and pre-embedded in the ground. Pre-embedding the fixing seat mechanism in the ground can increase its stability.

[0011] Preferably, the fixing base mechanism includes a fan-shaped flip plate, a hinge, a fan-shaped fixing plate, an arc-shaped partition plate one, an arc-shaped partition plate two, a battery module, ground nails, and a sealing gasket. The fan-shaped flip plate is disposed inside the cross-shaped limiting opening of the limiting base plate. A hinge is disposed between the fan-shaped flip plate and the limiting base plate. The fan-shaped flip plate is rotatably connected to the limiting base plate via the hinge. A fan-shaped fixing plate is fixedly connected to the center of the cross-shaped pre-embedded base. An arc-shaped partition plate one is fixedly connected inside the fan-shaped fixing plate. An arc-shaped partition plate two is fixedly connected to the edge. A ground nail is set between the arc-shaped partition plate one and the arc-shaped partition plate two. The ground nail penetrates the fan-shaped fixing plate. A sealing gasket is set at the position where the ground nail penetrates the fan-shaped fixing plate. The fan-shaped flip plate seals the top of the arc-shaped partition plate one and the arc-shaped partition plate two. The arc-shaped partition plate one and the arc-shaped partition plate two can seal the battery module and the ground nail when the top of the arc-shaped partition plate one and the arc-shaped partition plate two are closed, so as to prevent water from entering and affecting its service life. During maintenance, the fan-shaped flip plate can be opened for maintenance.

[0012] Preferably, both the fan-shaped flip plate and the fan-shaped fixing plate are fan-shaped panels. A battery module is fixedly connected between the arc-shaped inner opening of the arc-shaped partition plate and the cross-shaped pre-embedded base. The battery modules are separated by the cross-shaped pre-embedded base and the arc-shaped partition plate. By separating multiple battery modules, water ingress at the location of the battery modules can be avoided, which would cause multiple battery modules to become unusable at the same time, thus ensuring the stable operation of the equipment.

[0013] Preferably, the two first rhomboid support plates are far apart from each other, and the two second rhomboid support plates are far apart from each other. Both sides of the LED curved display screen one and the LED curved display screen two are screen surfaces, and both the LED curved display screen one and the LED curved display screen two are curved screens.

[0014] Preferably, the lifting support cylinder is welded through to the center of the cross-shaped pre-embedded base.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The LED curved display screen 1 and LED curved display screen 2 in this utility model can display information on all four sides of the road. The LED curved display screen 1 and LED curved display screen 2 can divert wind force from all four sides, which can reduce the wind force pushing the LED curved display screen 1 and LED curved display screen 2 and reduce damage to the device.

[0017] 2. In this utility model, the insertion plate and U-shaped limiting slot can be used to position and lift the lifting support rod in the vertical direction. When the pneumatic telescopic rod is activated to push the lifting support plate to rise, the insertion plate is inserted into the U-shaped limiting slot and slides up and down, so that the lifting support rod is located inside the lifting support cylinder and slides up and down. By pre-embedding the fixed seat mechanism in the ground, its stability can be increased.

[0018] 3. In this utility model, the arc-shaped partition plate 1 and arc-shaped partition plate 2 can seal the battery module and ground nail when the top of the arc-shaped partition plate 1 and arc-shaped partition plate 2 are closed, so as to prevent water from entering the inside and affecting the service life. During maintenance, the fan-shaped flip plate can be opened for maintenance. By separating multiple battery modules, water can be prevented from entering the location of the battery modules, which would cause multiple battery modules to be unusable at the same time, thus ensuring the stable operation of the equipment.
