Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an early warning device for edge protection during building construction. Background Art

[0002] Construction refers to the production activities during the implementation phase of a project, encompassing the construction of various buildings. It can also be described as the process of transforming the lines on a design drawing into a physical object at a designated location. During construction, it's often necessary to install warning devices in safe areas to alert nearby personnel to stay out of danger. Common warning devices typically consist of protective panels and warning lights, but the following shortcomings have been observed during their use.

[0003] Chinese patent CN220979078U discloses an early warning device for edge protection during construction, which relates to the technical field of construction protection devices. The technical solution includes a base and a support column, wherein the support columns are symmetrically welded on the left and right sides of the base, a protective plate is slidably connected to the base, and a buffer mechanism is equidistantly arranged on the sides of the protective plate. A pair of damping devices are symmetrically installed between the protective plate and the base, and tooth plates are symmetrically welded on the sides of the protective plate. A through groove is symmetrically opened on the side of the base, and a transmission gear is arranged in the through groove. The transmission gear is rotatably connected to the base via a round rod, and a sleeve is welded on the end of the round rod away from the transmission gear. Push blocks are symmetrically welded on the sides of the sleeve, and a support seat is welded in the through groove. A knocking bell is welded on the inner side of the support seat, and an early warning knocking device is arranged in the support seat. The beneficial effect of the utility model is to provide an early warning device for edge protection during construction.

[0004] In the above device, the transmission plate pushes the knocking block to hit the knocking bell to make a sound, thereby alerting the workers. However, during construction, the range of protective warnings varies in size. If the range is too large, multiple warning devices need to be set up, which requires greater costs for protective warnings. In addition, most warning mechanisms at the construction site are temporarily placed. After one construction is completed, they need to be dismantled and placed at another construction site. The above device is not convenient for rapid installation and dismantling, resulting in a lot of time required for installation and dismantling. In addition, the above device lacks a protective mechanism. If an emergency occurs at the construction site (such as stones, flying sand, etc.), there is nowhere to hide. Therefore, in addition to protective warnings, protective mechanisms need to be set up to prevent accidents. Utility Model Content

[0005] In order to solve the above technical problems, an early warning device for edge protection during construction is provided. This technical solution solves the above problems of inconvenience in rapid installation and dismantling and lack of protective mechanism.

[0006] In order to achieve the above purpose, the technical solution adopted by this utility model is:

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0027] Example 1

[0028] Please refer to Figure 1-Figure 5 As shown, an early warning device for edge protection during construction includes a placement box 1, and a warning mechanism 2 is installed inside the placement box 1. The warning mechanism 2 includes two groups of telescopic parts 201 and two groups of sliders 202. One end of the two groups of telescopic parts 201 is fixedly connected to the slider 202, and the slider 202 is slidably connected to the inside of the placement box 1. Several warning lights 207 are provided on the top of the telescopic parts 201, and the top of the placement box 1 is fixedly connected to the installation column 101. The outside of the installation column 101 is installed with a protective mechanism 3. The protective mechanism 3 includes four groups of support rods 302. The support rods 302 are arranged at the top of the installation column 101, and the outside of the support rods 302 is provided with a protective tarpaulin 303.

[0029] In this solution, the two sets of sliders 202 can slide inside the storage box 1. When the two sets of sliders 202 slide close to each other, the two sets of telescopic members 201 can quickly extend from the inside of the storage box 1 and deploy for protection, thereby being able to protect a larger area, reducing installation time and improving work efficiency. The warning light 207 is electrically connected to an external power supply, and the warning light 207 can mark the location of the telescopic member 201, thereby warning of the dangerous area. By installing the warning light 207 on the telescopic member 201, effective protection and early warning can be achieved.

[0030] Furthermore, when the two sets of sliders 202 slide away from each other, the telescopic member 201 can be driven to retract into the interior of the placement box 1 for removal, and the removal efficiency is high.

[0031] Furthermore, the protective tarpaulin 303 can be stretched out by the four sets of support rods 302 to provide protection. If debris falls from the air, nearby workers can quickly hide under the protective tarpaulin 303 to reduce the risk of worker injury.

[0032] Example 2

[0033] Please refer to Figure 2 As shown, the interior of the placement box 1 is rotatably connected to a bidirectional screw 105 via a bearing. Both ends of the bidirectional screw 105 are provided with threads with opposite rotation directions. Two sets of sliders 202 are threadedly connected to both ends of the bidirectional screw 105.

[0034] The inside of the storage box 1 is rotatably connected to a worm 102 via a bearing. The top of the bidirectional screw 105 is fixedly connected to a worm wheel 103 that meshes with the worm 102. One end of the worm 102 extends to the outside of the storage box 1 and is fixedly connected to a handle 104.

[0035] A cover plate 203 is provided at the other end of the telescopic member 201, and a fixed seat 204 is fixedly connected to the middle part of the outer side of the cover plate 203. The first swing arm 205 and the second swing arm 206 are rotatably connected inside the fixed seat 204. The other end of the telescopic member 201 is hinged to the first swing arm 205 and the second swing arm 206 respectively.

[0036] In this solution, the handle 104 can drive the worm 102 to rotate, so that the worm wheel 103 drives the bidirectional screw 105 to rotate, and then drives the two sets of sliders 202 to slide closer or slide away from each other. The telescopic member 201, the fixed seat 204, the first swing arm 205 and the second swing arm 206 can drive the cover 203 to extend out of the placement box 1, or move the cover 203 to the inside of the placement box 1, so that a closed space is formed between the two sets of cover plates 203 and the placement box 1, which can protect the telescopic member 201 and facilitate transportation.

[0037] Example 3

[0038] Please refer to Figure 3-Figure 5 As shown, the protective mechanism 3 also includes a transmission screw 307 and a slide 306. The transmission screw 307 is rotatably connected to the inside of the mounting column 101 through a bearing. The lower end of the transmission screw 307 extends to the inside of the placement box 1 and is fixedly connected to the worm gear 103. The slide 306 is threadedly connected to the transmission screw 307. Four groups of connecting rods 301 are provided on the outside of the slide 306. The end of the connecting rod 301 away from the slide 306 is connected to the lower end of the support rod 302.

[0039] Four sets of mounting seats 305 are fixedly connected to the outer side of the slide plate 306 , a connecting seat 304 is fixedly connected to the middle of the lower end of the support rod 302 , and both ends of the connecting rod 301 are hinged to the inner sides of the mounting seat 305 and the connecting seat 304 respectively.

[0040] Four sets of hinged seats 308 are fixedly connected to the top of the mounting column 101 , and one end of the support rod 302 is rotatably connected to the inside of the hinged seat 308 .

[0041] In this solution, one end of the mounting seat 305 extends to the outside of the mounting column 101 and is rotatably connected to the connecting rod 301. The worm gear 103 can drive the transmission screw 307 to rotate, thereby driving the slide 306 to move up and down, and can drive the four groups of mounting seats 305 to move up and down, thereby driving the connecting rod 301 to make the support rod 302 expand upward or contract downward, thereby driving the protective tarpaulin 303 to expand or contract. The worm 102 and the worm gear 103 can simultaneously control the bidirectional screw 105 and the transmission screw 307, thereby simultaneously controlling the expansion or contraction of the telescopic part 201 and the protective tarpaulin 303, thereby increasing the installation and disassembly efficiency of the present invention.

[0042] The working principle and usage process of the present invention are as follows: first, place the placement box 1 at the position where protection and warning are required, then turn the handle 104 and drive the worm 102 to rotate the worm wheel 103, thereby driving the bidirectional screw 105 to rotate, so that the two sets of sliders 202 slide close to each other, thereby driving the telescopic member 201 to extend from the inside of the placement box 1 and unfold for protection, and mark the position of the telescopic member 201 by the warning light 207, thereby warning the dangerous area. At the same time, the worm wheel 103 rotates and drives the transmission screw 307 to rotate, thereby driving the sliding plate 306 to move upward, and driving the four sets of mounting seats 305 to move upward, thereby driving the connecting rod 301 to make the support rod 302 unfold upward so that the protective tarpaulin 303 is opened. After the construction is completed, by reversing the handle 104, the telescopic member 201 is retracted to the inside of the placement box 1, and the protective tarpaulin 303 is retracted to the outside of the mounting column 101, which is convenient for movement and transportation.
