Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a safety warning device for construction engineering. Background Art

[0002] Construction projects refer to the general term for various types of buildings and engineering facilities that provide the material and technical basis for human life and production. They are organized, purposeful, large-scale economic activities of mankind. During the construction process, safety warning devices need to be set up to provide warnings.

[0003] Most commonly used safety warning devices are integrated, which makes it inconvenient to replace the warning signs in the safety warning devices, and most of the warning signs are directly exposed to the outside. During long-term use, they are exposed to wind and rain, which will cause the warning signs to rust, and then make the warning signs on the warning signs unclear, affecting subsequent use, thereby increasing the cost of using the safety warning device. Moreover, the position of the safety warning device is fixed after installation, which makes it inconvenient to adjust the overall height of the device.

[0004] In the prior art, a Chinese patent with a publication number of CN219862489U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a safety warning device for construction engineering, comprising a bottom plate and a protective box arranged on the top of the bottom plate, a warning sign body is arranged inside the protective box, and a clamping mechanism for limiting the position of the warning sign body is arranged inside the protective box, and a lifting mechanism for changing the height of the protective box is arranged on the top of the bottom plate; the utility model can protect the warning sign body through the protective box and the tempered glass, and extend the service life. By starting the driving mechanism, the distance between the two clamping plates on the two-way threaded rod can be adjusted. When the distance between the two clamping plates is the largest, the old warning sign body can be removed and a new warning sign body can be placed, so that different warning sign bodies can be replaced, which is conducive to reducing the use cost. The lifting mechanism can make the protective box rise or fall, and then the height of the warning sign body can be changed, but there will be a problem that the bottom plate is a fixed structure and the supporting area is also a fixed structure, which can easily cause the warning sign to fall due to external force. Summary of the invention

[0005] The purpose of the utility model is to provide a safety warning device for construction engineering to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A safety warning device for construction projects comprises a telescopic frame and a warning sign; a warning sign is fixedly installed on the top of the telescopic frame, a base is fixedly connected to the bottom of the telescopic frame, a plurality of rollers are fixedly installed on the bottom of the base, sliding frames are movably connected to both sides of the base, a plurality of second springs are fixedly installed inside the base, the outer side of each second spring is fixedly connected to the sliding frame, a rotating rod is rotatably installed on the top of the sliding frame, adjusting components are arranged on both sides of the telescopic frame, the adjusting components are used to adjust the position of the sliding frame, and a supporting component is arranged inside the sliding frame, the supporting component is used to support and limit the sliding frame.

[0008] By installing the rollers, the contact area between the base and the ground can be reduced, thereby facilitating the pushing of the base, driving the warning sign to move, and moving the warning sign to a suitable position, thereby improving the flexibility of the device; by adjusting the adjusting component, the distance between the sliding frame and the base can be expanded; at the same time, the elastic force of the second spring can be used to form a pulling force on the sliding frame toward the inside of the base, thereby limiting the sliding frame, thereby expanding the contact area between the base and the ground, and preventing the warning sign from tipping over due to external force; in the process of adjusting the sliding frame using the adjusting component, the supporting component can be used to connect the sliding frame to the ground, thereby limiting the sliding frame, preventing the roller from automatically rolling and causing the position of the warning sign to shift, thereby improving the stability of the device.

[0009] A further improvement of the technical solution of the utility model is that the adjusting component includes a fixing frame, which is fixedly connected to both sides of the telescopic frame, a screw rod is rotatably installed between the fixing frames through bearings, the outer periphery of the screw rod is rotatably connected to a slider, and the slider is rotatably connected to the top of the rotating rod.

[0010] The above technical solution is adopted. In this solution, the slider can be driven to move downward by rotating the screw rod, and the rotating rod can be driven to rotate at the same time, so that the sliding frame can be moved to both sides of the base, thereby expanding the contact area between the base and the ground.

[0011] A further improvement of the technical solution of the utility model is that a pulley is fixedly installed on the inner side of the sliding block, and the pulley is rollingly connected to the outer side of the telescopic frame.

[0012] By adopting the above technical solution, in this solution, the contact area between the slider and the telescopic frame can be reduced by installing a pulley, thereby avoiding friction between the slider and the telescopic frame during movement, reducing wear and extending the service life of the slider and the telescopic frame.

[0013] A further improvement of the technical solution of the utility model is that a hand wheel is rotatably mounted on the top of the fixed frame, and the hand wheel is fixedly connected to the top of the screw rod.

[0014] The above technical solution is adopted. In this solution, the contact area between the user's hand and the screw rod can be enlarged by installing a hand wheel, thereby facilitating the user to rotate the screw rod.

[0015] A further improvement of the technical solution of the utility model is that the supporting component includes a clamping block, which is slidably connected to the inside of the sliding frame, and first springs are fixedly installed at both ends of the clamping block, and the outer end of the first spring is fixedly connected to a supporting block, which passes through the bottom of the sliding frame, and an anti-slip pad is attached to the bottom of the supporting block.

[0016] The above-mentioned technical solution is adopted. In this solution, the elastic force of the first spring itself can generate a downward pulling force on the card block, and at the same time can drive the support block to move downward. When the bottom of the card block is not blocked, the support block can be pulled downward so that the anti-slip pad fits against the ground, and the sliding frame can be supported and limited, thereby improving the stability of the warning sign placement.

[0017] A further improvement of the technical solution of the utility model is that the bottom of the card block is an inclined surface inclined from the outside to the top of the inside, baffles are fixedly installed on both sides of the base, and the baffles are in contact with the bottom of the card block.

[0018] The above-mentioned technical solution is adopted. In this solution, the baffle plate can be used to cover the bottom of the card block, thereby separating the anti-skid pad from the ground, which is convenient for sliding the sliding frame. By setting the bottom of the card block to an inclined surface inclined from the outside to the top of the inside, when the sliding frame moves to the outside, the card block can be driven to move along with the top of the baffle plate, and the first spring is used to drive the card block and the support block to move slowly downward. When the sliding frame moves to the outermost side, the anti-skid pad just fits against the ground, and the user does not need to adjust the supporting component separately, thereby improving work efficiency.

[0019] A further improvement of the technical solution of the utility model is that a slide cylinder is slidably installed inside the base outside the second spring, and the slide cylinder is fixedly connected to the inner side of the slide frame.

[0020] By adopting the above technical solution, the contact area between the sliding frame and the base can be enlarged by installing the slide cylinder, so that the moving track of the sliding frame on both sides of the base can be guided and limited, thereby improving the sliding stability of the sliding frame.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a safety warning device for construction projects. By adjusting the mutual cooperation between the components, the sliding frame can be moved to both sides of the base using the screw rod, the slider and the rotating rod. At the same time, the second spring is used to generate a pulling force on the sliding frame, which can expand the contact area between the base and the ground, thereby preventing the warning sign from tipping over.

[0023] 2. The utility model provides a safety warning device for construction projects. Through the mutual cooperation between the supporting components, when the sliding frame is moved to both sides, the card block can be driven to move on the top of the baffle, and the first spring is used to drive the card block and the support block to move slowly downward. When the sliding frame moves to the outermost side, the anti-slip pad just fits against the ground, which can support and limit the sliding frame, thereby improving the stability of the warning sign placement.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a safety warning device for construction engineering, including a telescopic frame 2 and a warning sign 3; the warning sign 3 is fixedly installed on the top of the telescopic frame 2, the bottom of the telescopic frame 2 is fixedly connected to the base 1, the bottom of the base 1 is fixedly installed with a plurality of rollers 101, the two sides of the base 1 are movably connected with sliding frames 4, the inside of the base 1 is fixedly installed with a plurality of second springs 8, the outer side of each second spring 8 is fixedly connected to the sliding frame 4, the top of the sliding frame 4 is rotatably installed with a rotating rod 6, the two sides of the telescopic frame 2 are provided with adjusting components 5, the adjusting components 5 are used to adjust the position of the sliding frame 4, the inside of the sliding frame 4 is provided with a supporting component 7, the supporting component 7 is used to support and limit the sliding frame 4.

[0036] In this embodiment, the contact area between the base 1 and the ground can be reduced by installing the roller 101, thereby facilitating pushing the base 1, driving the warning sign 3 to move, and moving the warning sign 3 to a suitable position, thereby improving the flexibility of the device. By adjusting the adjusting component 5, the distance between the sliding frame 4 and the base 1 can be expanded. At the same time, the elastic force of the second spring 8 itself can be used to form a pulling force on the sliding frame 4 toward the inside of the base 1, thereby limiting the sliding frame 4, thereby expanding the contact area between the base 1 and the ground, and preventing the warning sign 3 from tipping over due to external force. In the process of adjusting the sliding frame 4 using the adjusting component 5, the supporting component 7 can be used to connect the sliding frame 4 to the ground, thereby limiting the sliding frame 4, preventing the roller 101 from automatically rolling and causing the position of the warning sign 3 to be offset, thereby improving the stability of the device.

[0037] Example 2

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the adjusting component 5 includes a fixed frame 501, which is fixedly connected to both sides of the telescopic frame 2, and a screw rod 502 is rotatably installed between the fixed frames 501 through bearings, and a slider 503 is rotatably connected to the outer periphery of the screw rod 502, and the slider 503 is rotatably connected to the top of the rotating rod 6, a pulley 504 is fixedly installed on the inner side of the slider 503, and the pulley 504 is rollingly connected to the outer side of the telescopic frame 2, and a hand wheel 505 is rotatably installed on the top of the fixed frame 501, and the hand wheel 505 is fixedly connected to the top of the screw rod 502.

[0039] In this embodiment, by rotating the screw rod 502, the slider 503 can be driven to move downward, and at the same time, the rotating rod 6 can be driven to rotate, so that the sliding frame 4 can be moved to both sides of the base 1, thereby expanding the contact area between the base 1 and the ground. By installing the pulley 504, the contact area between the slider 503 and the telescopic frame 2 can be reduced, thereby avoiding friction between the slider 503 and the telescopic frame 2 during the movement, reducing wear and extending the service life of the slider 503 and the telescopic frame 2. By installing the handwheel 505, the contact area between the user's hand and the screw rod 502 can be expanded, thereby facilitating the user to rotate the screw rod 502.

[0040] Example 3

[0041] like Figure 2 , Figure 3 and Figure 6 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the supporting component 7 includes a card block 701, which is slidably connected to the inside of the sliding frame 4, and the first springs 702 are fixedly installed at both ends of the card block 701, and the outer end of the first spring 702 is fixedly connected to a support block 703, and the support block 703 passes through the bottom of the sliding frame 4, and an anti-slip pad 705 is attached to the bottom of the support block 703. The bottom of the card block 701 is an inclined surface inclined from the outside to the top of the inside, and baffles 704 are fixedly installed on both sides of the base 1, and the baffles 704 are in contact with the bottom of the card block 701.

[0042] In this embodiment, the elastic force of the first spring 702 can be used to generate a downward pulling force on the card block 701, and at the same time, the support block 703 can be driven to move downward. When the bottom of the card block 701 is not blocked, the support block 703 can be pulled downward to make the anti-skid pad 705 fit the ground, and the sliding frame 4 can be supported and limited, thereby improving the stability of the warning sign 3. The baffle plate 704 can be used to block the bottom of the card block 701, so that the anti-skid pad 705 can be separated from the ground. To facilitate the sliding of the sliding frame 4, the bottom of the card block 701 is set to an inclined surface inclined from the outside to the inside. When the sliding frame 4 moves toward the outside, the card block 701 can be driven to move along with the top of the baffle 704. At the same time, the first spring 702 is used to drive the card block 701 and the support block 703 to move slowly downward. When the sliding frame 4 moves to the outermost side, the anti-slip pad 705 just fits against the ground, and the user does not need to adjust the support component 7 separately, thereby improving work efficiency.

[0043] Example 4

[0044] like Figure 2 , Figure 3 and Figure 5As shown, based on Example 1, the utility model provides a technical solution: preferably, a slide cylinder 401 is slidably installed inside the base 1 outside the second spring 8, and the slide cylinder 401 is fixedly connected to the inner side of the sliding frame 4.

[0045] In this embodiment, the contact area between the sliding frame 4 and the base 1 can be expanded by installing the slide cylinder 401, so that the moving track of the sliding frame 4 on both sides of the base 1 can be guided and limited, thereby improving the sliding stability of the sliding frame 4.

[0046] The following is a detailed description of the working principle of the safety warning device for construction projects.

[0047] like Figure 1-Figure 7 As shown, the user uses the roller 101 to move the warning sign 3 to a suitable position and then stops, and then uses the handwheel 505 to rotate the screw rod 502, which can drive the slider 503 to move downward, and at the same time drive the rotating rod 6 to rotate, so as to realize the movement of the sliding frame 4 to both sides. During the adjustment, the block 701 can be driven to move on the top of the baffle 704. When the baffle 704 and the inclined surface of the block 701 contact each other, the first spring 702 is used to drive the block 701 and the support block 703 to move slowly downward. When the sliding frame 4 moves to the outermost side, the anti-slip pad 705 just fits against the ground, so that the sliding frame 4 can be supported and limited, which is convenient for the use of the warning sign 3.

[0048] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
