And an early warning function is not set for the deviation of the protective fence, so that an operator cannot find the deviation of the protective fence in time, and the falling risk of the protective fence is increased.

Description

Technical Field

[0001] The utility model relates to the technical field of building construction protection, in particular to an anti-falling type building construction site protection fence. Background Art

[0002] Building construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. During the construction process, operators often need to work at high places in buildings. In order to prevent operators from falling from heights, guardrails need to be installed in places such as roofs and floor edges.

[0003] According to the announcement number: CN220686949U, a construction site guardrail is disclosed, which belongs to the technical field of construction equipment. The limiting column is installed at the bottom of the limiting groove by clamping, and the overall positioning of the limiting column and the sliding column and the universal wheel are completed, ensuring that the universal wheel is in the pushed-out state. At this time, the guardrail body can be moved. When multiple guardrail bodies are connected to each other, the overall movement of the guardrail body can be achieved without disassembly, thereby improving the overall work efficiency. The construction site guardrail includes a guardrail body, the guardrail body is a rectangular frame structure, and the bottom of the two sections of the guardrail body are both protrudingly provided with supporting legs. A U-shaped fixing frame is symmetrically inserted and installed in the guardrail body, and the bottom of the fixing frame is symmetrically installed with universal wheels. A pedal assembly supported by an auxiliary fixing frame is installed at the inner bottom of the guardrail body.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem of existing on-site guardrails, when they need to be moved after splicing and installation, they need to be disassembled one by one and then moved to the corresponding position. The process of moving and transporting is overall troublesome and the work efficiency is low.

[0005] However, it was found during actual use that when installing guardrails, it is usually adopted to directly place the guardrails in the protective position without secondary reinforcement of the guardrails. When the guardrails are used at high places, the friction between the height and the ground is weaker, and the air flows more freely, which in turn causes the wind speed to increase, causing the wind to blow the guardrails close to the roof and the edge of the floor. Since there is no early warning function for the offset of the guardrail, the operator cannot detect the deviation of the guardrail in time, increasing the risk of the guardrail falling. Utility Model Content

[0006] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a fall-proof construction site guardrail, which has the advantage of auxiliary stability and solves the problem that when the guardrail is used at a height, the friction between the height and the ground is weaker, the air flows more freely, and the wind speed increases, so that the wind will blow the guardrail close to the roof and the edge of the floor. Since there is no early warning function for the deviation of the guardrail, the operator cannot detect the deviation of the guardrail in time, which increases the risk of the guardrail falling.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fall-proof construction site guardrail, comprising a base, a guardrail body and a ground, the base being located at the top of the ground, the guardrail body being fixedly connected to the top of the base, a pull-rope displacement sensor being fixedly connected to the top of the base, the detection end of the pull-rope displacement sensor being fixedly installed to the ground through expansion bolts, an early warning mechanism being fixedly connected to the top of the guardrail body, and an anti-fall mechanism being fixedly installed on the rear side of the top of the ground through expansion bolts.

[0008] As a preferred embodiment of the utility model, the early warning mechanism includes a controller, the controller is fixedly connected to the top inside the guardrail body, a warning light is fixedly connected to the left side of the top of the guardrail body, the controller is electrically connected to the warning light through a wire, and the pull-rope displacement sensor is electrically connected to the controller through a wire.

[0009] As a preferred embodiment of the utility model, the anti-fall mechanism includes a winch, the winch is fixedly installed on the rear side of the top of the ground by expansion bolts, the winch is electrically connected to the controller by wires, a winding rope is wound inside the winch, one end of the winding rope is fixedly connected to the winch, and the other end of the winding rope is fixedly connected to the guardrail body.

[0010] As a preferred embodiment of the present invention, a buzzer is fixedly connected to the right side of the top of the guardrail body, and the buzzer is electrically connected to the controller through a wire.

[0011] As a preferred embodiment of the present invention, a protection box is fixedly connected to the top of the interior of the guardrail body, and the controller is located inside the protection box.

[0012] As a preferred embodiment of the utility model, a loudspeaker is fixedly connected to the top of the buzzer, and the loudspeaker is larger at the top and smaller at the bottom.

[0013] As a preferred embodiment of the present invention, the front side of the protection box is movably connected with a switch door via a hinge.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a pull-rope displacement sensor, an early warning mechanism and an anti-fall mechanism. When the guardrail body is displaced, the pull rope will stretch or contract accordingly, causing the internal sensing element to rotate, thereby outputting an electrical signal proportional to the displacement, so that the electrical signal is transmitted to the early warning mechanism and the anti-fall mechanism through a wire, so that the early warning mechanism reminds the operator. At the same time, when the deviation is too large, the anti-fall mechanism will limit the guardrail body to prevent the guardrail body from falling. This solves the problem that when the guardrail is used at a high place, the friction between the high place and the ground is weak, and the air flows more freely, which leads to an increase in wind speed, so that the wind will blow the guardrail close to the roof and the edge of the floor. Since there is no early warning function for the deviation of the guardrail, the operator cannot discover the deviation of the guardrail in time, which increases the risk of the guardrail falling, and achieves the effect of auxiliary stabilization.

[0016] 2. The utility model provides an early warning mechanism so that the pull-rope displacement sensor is electrically connected to the controller through a wire. By setting a first threshold value inside the controller, when the guardrail body is displaced, the pull rope will stretch or contract accordingly, causing the internal sensing element to rotate, thereby outputting an electrical signal proportional to the displacement, and the electrical signal is transmitted to the inside of the controller through the wire, so that the controller performs data analysis on the transmitted electrical signal. When the structure after analysis reaches the first threshold value, the controller adjusts the warning light to emit alternating red and blue flashing light to remind the operator that the guardrail body is offset, thereby avoiding a larger offset of the guardrail body.

[0017] 3. The utility model provides an anti-fall mechanism and sets a second threshold value inside the controller. When the controller performs data analysis on the transmitted electrical signal and the structure after analysis reaches the second threshold value, the controller starts the winch to reel in the winding rope, so that the winding rope can hook the guardrail body to prevent the guardrail body from deviating too much and falling.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The controller 51 is electrically connected to the warning light 52 through a wire, and the pull-rope displacement sensor 4 is electrically connected to the controller 51 through a wire.

[0025] As a technical optimization scheme of the utility model, by setting an early warning mechanism 5, the pull-rope displacement sensor 4 is electrically connected to the controller 51 through a wire, and by setting a first threshold value inside the controller 51, when the guardrail body 2 is displaced, the pull rope will stretch or contract accordingly, causing the internal sensing element to rotate, thereby outputting an electrical signal proportional to the displacement, and the electrical signal is transmitted to the inside of the controller 51 through the wire, so that the controller 51 performs data analysis on the transmitted electrical signal. When the structure after analysis reaches the first threshold value, the controller 51 regulates the warning light 52, so that the warning light 52 emits alternating red and blue flashing light to remind the operator that the guardrail body 2 is offset, thereby avoiding a larger offset of the guardrail body 2.

[0026] refer to Figure 2 and Figure 3 The anti-fall mechanism 6 includes a winch 61, which is fixedly installed on the rear side of the top of the ground 2 by expansion bolts. The winch 61 is electrically connected to the controller 51 through a wire. A winding rope 62 is wound inside the winch 61, one end of the winding rope 62 is fixedly connected to the winch 61, and the other end of the winding rope 62 is fixedly connected to the guardrail body 2.

[0027] As a technical optimization scheme of the utility model, an anti-fall mechanism 6 is provided, and a second threshold is set inside the controller 51. When the controller 51 performs data analysis on the transmitted electrical signal, when the structure after analysis reaches the second threshold, the controller 51 starts the winch, and the winch 61 reels the winding rope 62, so that the winding rope 62 can hook the guardrail body 2, thereby preventing the guardrail body 2 from deviating too much and falling.

[0028] refer to Figure 2 and Figure 3 A buzzer 7 is fixedly connected to the right side of the top of the guardrail body 2, and the buzzer 7 is electrically connected to the controller 51 through a wire.

[0029] As a technical optimization solution of the utility model, by setting a buzzer 7, when the controller 51 adjusts the warning light 52, the controller 51 turns on the buzzer 7, and then the buzzer 7 makes a sound to remind the operator, thereby improving the warning effect.

[0030] refer to Figure 3 A protection box 8 is fixedly connected to the top of the guardrail body 2 , and the controller 51 is located inside the protection box 8 .

[0031] As a technical optimization solution of the utility model, a protection box 8 is provided and fixedly installed on the guardrail body 2, so that the protection box 8 can protect the controller 51 and prevent the controller 51 from being damaged by external impact or dust.

[0032] refer to Figure 1 A loudspeaker 9 is fixedly connected to the top of the buzzer 7, and the loudspeaker 9 is arranged to be larger at the top and smaller at the bottom.

[0033] As a technical optimization solution of the utility model, by providing a megaphone 9 that is larger at the top and smaller at the bottom, when the buzzer 7 makes a sound, the megaphone 9 can increase the sound propagation range and further improve the effect of warning the operator.

When the operator needs to use the controller 51, the operator can open the switch door 10, so that the operator can conveniently use the controller 51.

[0036] The working principle and use process of the utility model are as follows: when in use, the operator first sets the first threshold value and the second threshold value in the controller 51, and then the detection end of the pull rope displacement sensor 4 is installed with the ground 2 through the expansion bolt. When the guardrail body 2 is displaced, the pull rope will stretch or contract accordingly, causing the internal sensing element to rotate, thereby outputting an electrical signal proportional to the displacement, so that the electrical signal is transmitted to the controller 51 through the wire, and the controller 51 performs data analysis on the transmitted electrical signal. When the structure after analysis reaches the first threshold value, the controller 51 turns on the warning light 5. 2 is regulated so that the warning light 52 emits red and blue flashing lights alternately to remind the operator that the guardrail body 2 is offset. When the controller 51 regulates the warning light 52, the controller 51 turns on the buzzer 7, which makes the buzzer 7 emit a sound to remind the operator to avoid a larger offset of the guardrail body 2. When the analyzed structure reaches the second threshold, the controller 51 starts the winch, so that the winch 61 reels the reeling rope 62, so that the reeling rope 62 can hook the guardrail body 2 to avoid the guardrail body 2 from deviating too much and falling.

[0037] To sum up: this anti-falling type construction site guardrail, by setting a pull-rope displacement sensor 4, an early warning mechanism 5 and an anti-falling mechanism 6, when the guardrail body 2 is displaced, the pull rope will stretch or contract accordingly, causing the internal sensing element to rotate, thereby outputting an electrical signal proportional to the displacement, so that the electrical signal is transmitted to the early warning mechanism 5 and the anti-falling mechanism 6 through a wire, so that the early warning mechanism 5 reminds the operator, and at the same time, when the deviation is too large, the anti-falling mechanism 6 will limit the guardrail body 2 to prevent the guardrail body 2 from falling, which solves the problem that when the guardrail is used at a high place, the friction between the high place and the ground is weak, the air flows more freely, and the wind speed increases, so that the wind will blow the guardrail close to the roof and the edge of the floor. Since there is no early warning function for the deviation of the guardrail, the operator cannot discover the deviation of the guardrail in time, increasing the risk of the guardrail falling.
