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 in excavation construction. Background Art

[0002] In the field of excavation engineering, safety assurance is always the top priority. During the excavation operation, there are many safety hazards such as slope collapse and personnel falling, so it is crucial to provide effective safety warnings at the construction site. At present, some excavation construction sites use "an early warning device for edge protection of building construction" with patent number 202323344857.9 to provide warnings. By setting telescopic components and adjustment components, the height of the early warning signal light can be flexibly adjusted, which simplifies the operation process and enhances the flexibility of the device, providing certain conveniences for the safety management of excavation construction. However, this type of early warning device lacks consideration in terms of power consumption.

[0003] In the prior art, because of the complex working environment and long construction period at the excavation construction site, the early warning device is often required to operate 24 hours a day. From the perspective of energy supply, the existing excavation construction process is analyzed. The power supply conditions at the excavation construction site are often subject to many restrictions, and there may be problems such as unstable power supply and limited power capacity. At the same time, multiple early warning devices operate with high power consumption 24 hours a day, which can easily lead to power overload at the construction site and affect the normal operation of other construction equipment. Once the above-mentioned power supply shortage occurs, not only will the early warning device fail to play a normal warning role, but it will also increase the risk of safety accidents. It may also cause the excavation construction progress to be forced to be interrupted, causing delays in the construction period.

[0004] Because the sensors on the existing excavation construction site warning device work continuously, the high power consumption of the excavation construction site warning device during 24-hour operation seriously restricts its wide application in excavation engineering. Therefore, developing a low-energy consumption, high-performance excavation construction site warning device to effectively reduce its 24-hour power consumption has become a key issue that needs to be urgently solved in the current excavation engineering technology field.

[0005] In order to overcome the above shortcomings, the inventor invented an early warning device for edge protection during excavation construction. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an early warning device for edge protection of excavation construction, which can be powered on when personnel approach the device, reducing power consumption during 24-hour operation, and the power load on the construction site is not easily overloaded, thereby realizing a low-energy consumption, high-performance early warning device for the excavation construction site, effectively preventing the hazards caused by slope collapse and falling of personnel, and will not cause delays in the construction period.

[0007] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0008] An early warning device for edge protection during excavation construction comprises a pedal and a pull rod, one end of the pedal is hinged to a first pull ring, the top of the first pull ring is fixedly connected to the bottom of the pull rod, the top of the pull rod is fixedly connected to the bottom of a second pull ring, the second pull ring is hinged to a fence vertical bar, the fence vertical bar is hinged to one end of a fence cross bar, the middle of the fence cross bar is hinged to the middle section of a fixed pile, and the other end of the fence cross bar is hinged to the side of a warning connecting sign; a warning light is provided on the fence cross bar hinged to the warning sign.

[0009] As a further implementation, the bottom of the warning light is connected to the neutral line output terminal, and the side of the base of the warning light is connected to the live line output terminal.

[0010] As a further implementation method, the neutral wire is fixed at the bottom of the fence crossbar, and the live wire is fixed at the top of the fence crossbar; the neutral wire input end is connected to the second induction iron sheet, and the live wire input end is connected to the first induction iron sheet.

[0011] As a further implementation, a power supply is arranged behind the fixing pile, the positive pole of the power supply is connected to the first electrode spring, the negative pole of the power supply is connected to the second electrode spring, and the first electrode spring is located above the second electrode spring.

[0012] As a further implementation, top ends of the first electrode spring and the second electrode spring both extend out of the outer surface of the fixing pile.

[0013] As a further implementation, when the fence vertical pole is close to the fixed pile, the first electrode spring contacts the first inductive iron sheet, and the second electrode spring contacts the second inductive iron sheet.

[0014] As a further implementation, the bottom of the fixing pile is arranged on the ground by bolts.

[0015] As a further implementation, a warning connection sign reads "Construction ahead, please do not enter."

[0016] As a further implementation, in a non-working state, one end of the pedal away from the fixed pile contacts the ground, and the entire pedal remains inclined with respect to the ground.

[0017] The beneficial effects of the utility model are as follows:

[0018] The warning light of the utility model will only light up when a person or vehicle approaches and steps on the pedal. In the non-working state, the warning light does not consume electricity. Only after the pedal is triggered, the connection between the power supply and the warning light is completed through a series of mechanical actions, so that the warning light is turned on, avoiding the warning light from running uninterruptedly for 24 hours. Electric energy is consumed only when someone approaches and there may be danger. This design significantly reduces the waste of electric energy, reduces the energy consumption of the power supply, and effectively reduces its 24-hour power consumption.

[0019] The entire device of the utility model turns on the warning light by mechanical triggering. After the pedal is stepped on, the vertical bar of the fence is moved close to the fixed pile through the movement of a series of mechanical parts such as the pull rod and the pull ring, and the vertical bar of the fence pulls the horizontal bar of the fence to tilt, and then the first induction iron sheet and the second induction iron sheet on the horizontal bar of the fence move downward, and finally the connection between the power supply and the warning light is completed. This mechanical triggering method avoids the use of complex electronic sensors or continuously powered electronic components to detect the approach of people or vehicles. Mechanical triggering is not only simple and reliable, but also reduces the energy consumption of electronic components, further reducing the overall power consumption of the device, and realizing a low-energy, high-performance excavation construction site early warning device. The power load at the excavation construction site is not easy to overload, which ensures sufficient power supply, effectively prevents the hazards caused by slope collapse and falling of people, and will not cause delays in the construction period.

DETAILED DESCRIPTION Example

[0027] This embodiment provides an early warning device for edge protection in excavation construction, as shown in FIG1- Figure 5 As shown, it includes a pedal 1 and a pull rod 2. The pedal 1 is for approaching people and vehicles to step on. One end of the pedal 1 is hinged to the first pull ring 3. When the pedal 1 is stepped on and pressed down, the pedal 1 then pulls the first pull ring 3 downward. The top of the first pull ring 3 is fixedly connected to the bottom end of the pull rod 2. When the first pull ring 3 is pulled downward, the pull rod 2 is also pulled downward. The top of the pull rod 2 is fixedly connected to the bottom of the second pull ring 4. When the pull rod 2 is pulled downward, the second pull ring 4 is also pulled downward. The second pull ring 4 is hinged to the fence vertical rod 5. The second pull ring 4 drives the fence vertical rod 5 to move downward together. The fence vertical bar 5 is hinged to one end of the fence cross bar 6. There are two fence cross bars 6, and the two fence cross bars 6 are arranged in parallel with each other. The middle of the fence cross bar 6 is hinged to the middle section of the fixed pile 13. When one end of the fence cross bar 6 is pulled downward, the other end of the fence cross bar 6 (that is, the end away from the fixed pile 13) will tilt up, and the other end of the fence cross bar 6 (that is, the end away from the fixed pile 13) is hinged to the side of the warning sign 7; a warning light 8 is provided on the fence cross bar 6 hinged to the warning sign 7, and the warning light 8 is installed on the lowest cross bar among all the fence cross bars 6.

[0028] The bottom of the warning light 8 is connected to the neutral line output terminal, and the side of the base of the warning light 8 is connected to the live line output terminal. This enables the warning light 8 to distinguish between the neutral line and the live line, and this connection method can ensure that the warning light 8 works normally.

[0029] The neutral line is fixed at the bottom of the fence crossbar 6, and the live line is fixed at the top of the fence crossbar 6; the live line and the neutral line are both arranged parallel to the surface of the fence crossbar 6, and then the live line and the neutral line are bent and extended backward at the same length position, and a live line input terminal is arranged at the end of the live line extension, and a neutral line input terminal is arranged at the end of the neutral line extension, and a second induction iron sheet 10 is connected to the neutral line input terminal, and a first induction iron sheet 9 is connected to the live line input terminal, and the first induction iron sheet 9 and the second induction iron sheet 10 are both arranged behind the fence crossbar 6. The design of the first induction iron sheet 9 and the second induction iron sheet 10 increases the probability of contact with the power supply 14 (because the contact area of ​​the iron sheet is relatively large, so the probability of contact connection is relatively large), and this design enables the warning light 8 to quickly establish a connection with the power supply 14.

[0030] The first induction iron sheet 9 and the second induction iron sheet 10 are both designed to be circular. If there is a production requirement, the first induction iron sheet 9 and the second induction iron sheet 10 can be designed to be other shapes, such as a rectangle.

[0031] A power source 14 is arranged behind the fixed pile 13, the positive pole of the power source 14 is connected to the first electrode spring 11, the negative pole of the power source 14 is connected to the second electrode spring 12, and the first electrode spring 11 is located above the second electrode spring 12. This is to more efficiently distinguish the positive and negative poles without interfering with each other, and is also beneficial: when the pedal 1 is pressed down, the first induction iron sheet 9 contacts the first electrode spring 11, the second induction iron sheet 10 contacts the second electrode spring 12, and the two different electrodes do not interfere with each other.

[0032] The top ends of the first electrode spring 11 and the second electrode spring 12 extend out of the outer surface of the power source 14 . This design is also conducive to the first induction iron sheet 9 contacting the first electrode spring 11 , and the second induction iron sheet 10 contacting the second electrode spring 12 .

[0033] As the pedal 1 is pressed down, when the fence vertical bar 5 approaches the fixed pile 13, the part of the fence horizontal bar 6 hinged to the fence vertical bar 5 also approaches the fixed pile 13, so that the first electrode spring 11 contacts the first induction iron sheet 9, and the second electrode spring 12 contacts the second induction iron sheet 10. At this time, the connection between the power supply 14 and the warning light 8 is completed, and the warning light 8 lights up.

[0034] The bottom of the fixing pile 13 is set on the ground by bolts. This design scheme realizes stable support and stable standing of the fixing pile 13.

[0035] The warning sign 7 has "Construction ahead, please do not enter" written on it, and the warning sign 7 has black text on a yellow background. Because the warning sign 7 is relatively close to the warning light 8, even at night, the words "Construction ahead, please do not enter" on the warning sign 7 will be illuminated by the warning light 8, and the visual effect of the warning is better, which can achieve efficient early warning.

[0036] If necessary for production, the warning statement on the warning sign 7 can be replaced with other statements, such as "Excavation ahead, please do not enter" or "Slope collapse ahead, no entry", which can serve as a warning.

[0037] The pedal 1 is hinged to the rope 17 at the end away from the fixed pile 13, and the fixed pulley 15 is set on one side of the positioning pile 18. The rope 17 is finally connected to the counterweight 16 after passing through the fixed pulley 15. At this moment, the function of the counterweight 16 is to balance the traction on both sides of the pedal 1, so that the left and right sides of the pedal 1 can maintain balanced movement along the positive direction of the pedal 1 regardless of whether the pedal 1 is tilted or horizontal.

[0038] In the non-working state (that is, when there are no pedestrians or vehicles on the pedal), the end of the pedal 1 away from the fixed pile 13 is in contact with the ground. Because the gravity of the counterweight 16 pulls the pedal 1 upward through the rope 17, and also because of the own gravity of the fence cross bar 6, the end of the pedal 1 close to the fixed pile 13 is lifted, and the entire pedal 1 remains inclined with respect to the ground, the fence vertical bar 5 remains vertical, and the fence cross bar 6 remains horizontal. At this time, the first electrode spring 11 does not contact the first induction iron sheet 9, and the second electrode spring 12 does not contact the second induction iron sheet 10.

[0039] After the pedal 1 is stepped on by approaching people and vehicles, the side of the pedal 1 close to the fixed pile 13 is pressed downward, and then the pedal 1 drives the first pull ring 3 to pull downward, thereby overcoming the self-gravity of the fence cross bar 6, and realizing the static to dynamic change of the fence cross bar 6.

[0040] The working voltage of the power supply 14 is not more than 35V and greater than 18V. This working voltage can drive the warning light 8 and will not harm human health. This working voltage can drive the warning light 8 to work normally and will not harm human health. Compared with high-voltage driven equipment, under the premise of meeting the warning function, low voltage means lower power consumption, which reduces the consumption of electric energy from the supply side of the power supply 14.

[0041] The warning light 8 will not consume electricity when the power supply 14 is not connected. Only when a person or vehicle approaches and steps on the pedal 1, a series of mechanical actions will be triggered. The pedal 1 is pressed down to drive the pull rod 2, the first pull ring 3, the second pull ring 4 and other components to move, so that the fence vertical rod 5 is close to the fixed pile 13, and then the first electrode spring 11 contacts the first induction iron sheet 9, and the second electrode spring 12 contacts the second induction iron sheet 10, completing the connection between the power supply 14 and the warning light 8, and the warning light 8 will light up and start working. This design avoids the warning light 8 from running uninterruptedly for 24 hours, and only consumes electricity when someone approaches and there may be danger, avoiding the warning device from occupying a large amount of electricity.

[0042] According to the production requirements, the fence crossbar 6 can be set to more than two. The present application is set at the edge of the excavation construction.
