Description

Technical Field

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

[0002] Engineering construction refers to the activities of new construction, expansion and reconstruction of the construction projects on the contract after the construction and installation company signs the relevant contract with the entrusting unit, in accordance with the requirements of the construction project design documents. In order to increase the safety of the construction process, it is often necessary to use corresponding warning fences to warn unauthorized personnel not to enter the fence.

[0003] The utility model with the existing authorization announcement number CN219344287U discloses a safety protection fence for power engineering construction. By providing a movable fence and a flippable warning sign, when the fence is placed on the road, in order to enable drivers to notice it from a distance and give them a certain early warning effect, the warning sign is first flipped upward and fixed by a locking mechanism, and then the movable fence is stretched upward to raise it. In this way, the warning sign can be placed in a higher position. When the driver passes the road section, he can notice the warning sign and make avoidance in advance.

[0004] Although the flippable warning sign can make the driver notice it from a distance and thus have a better warning effect, the above technical solution lacks an anti-crossing alarm structure to prevent outsiders from crossing, which makes it easy for outsiders to cross the fence and pose a safety risk.

[0005] Therefore, those skilled in the art provide a warning fence for engineering construction to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to provide a warning fence for engineering construction to solve the problems raised in the above background technology.

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

[0008] A warning fence for engineering construction, comprising a guardrail, wherein an anti-crossing alarm mechanism is arranged above the guardrail;

[0009] The anti-crossing alarm mechanism includes a shell, the front side of the shell is respectively fixedly connected with a controller and an alarm, the interior of the shell is slidably connected with a slide board, the upper surface of the slide board is fixedly connected with a plurality of identical storage tubes, the inner wall of the slide board is threadedly connected with two hand-tightened bolts, the interior of each of the storage tubes is slidably connected with a conical column, the inner bottom wall of each of the storage tubes is fixedly connected with a pressure sensor, and a rebound spring is arranged inside each of the storage tubes.

[0010] As a further solution of the utility model: the bottom surface of the shell is fixedly connected to the upper surface of the guardrail, two support plates are arranged below the guardrail, and the upper surface of each support plate is fixedly connected to the bottom surface of the guardrail with a support column.

[0011] As a further solution of the utility model: both side surfaces of each support plate are fixedly connected with a mounting plate, and the upper surface of each mounting plate is provided with two mounting holes.

[0012] As a further solution of the utility model: the outer surfaces of several of the storage tubes and the two hand-tightened bolts are slidably connected to the interior of the shell, the front of the slide plate is fixedly connected to two handle rods, the outer surface of each of the handle rods is fixedly connected to an anti-slip sleeve, and the outer surface of each of the handle rods is slidably connected to the interior of the shell.

[0013] As a further solution of the utility model: a number of identical pressure sensors and alarms are electrically connected to the controller through wires, the outer surface of each hand-tightened bolt is provided with a non-slip soft gasket, and the back side of each non-slip soft gasket is in contact with the front side of the shell.

[0014] As a further solution of the utility model: the two ends of each of the return springs are respectively in contact with the bottom end of the conical column and the upper surface of the pressure sensor, the back of the shell is fixedly connected with a reflector, and the bottom surface of the guardrail is fixedly connected with a bottom baffle.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model is provided with a guardrail, a shell, a controller, an alarm, a slide plate, a hand-tightened bolt, a storage tube, a conical column, a rebound spring and a pressure sensor which cooperate with each other. When the anti-crossing alarm mechanism is used, the slide plate can slide up to make the conical column extend out of the shell. The hand-tightened bolt presses the outer surface of the shell to fix the height of the slide plate relative to the inside of the shell. When someone wants to cross the fence, the sharp conical column can play the first step of deterrence. When someone wants to cross the fence, pressing the conical column can compress the rebound spring. The rebound of the rebound spring can give a large pressure change to the pressure sensor. The pressure sensor can transmit the large pressure change to the controller, and then the controller can control the alarm to emit an alarm sound, thereby warning the crosser and providing a warning signal to surrounding construction personnel, thereby achieving the effect of anti-crossing and alarm warning, and avoiding the problem that outsiders easily cross the fence and have safety risks due to the lack of an anti-crossing alarm structure to prevent outsiders from crossing.

The upper surface of each support plate 4 is fixedly connected with a support column 3 together with the bottom surface of the guardrail 1. By providing the support column 3, the support plate 4 and the guardrail 1 can be connected. By providing the support plate 4, the contact area between the bottom end of the support column 3 and the bottom surface can be increased, thereby improving the support stability of the upper structure.

[0023] The inside of the shell 201 is slidably connected to a slide plate 204, and a plurality of identical storage tubes 206 are fixedly connected to the upper surface of the slide plate 204. The two side surfaces of each support plate 4 are fixedly connected to mounting plates 5, and the upper surface of each mounting plate 5 is provided with two mounting holes 6. By providing the mounting plates 5 and the mounting holes 6, the support plates 4 can be fastened to the docking structure embedded in the ground in conjunction with an external bolt or a positioning pin structure, thereby facilitating the fixing of the entire fence.

[0024] The inner wall of the skateboard 204 is threadedly connected to two hand-tightening bolts 205, and the interior of each storage tube 206 is slidably connected to a tapered column 207. The outer surfaces of several storage tubes 206 and the two hand-tightening bolts 205 are slidably connected to the interior of the shell 201. The front of the skateboard 204 is fixedly connected to two grip rods 7, and the outer surface of each grip rod 7 is fixedly connected to an anti-slip sleeve 8. The outer surface of each grip rod 7 is slidably connected to the interior of the shell 201. By providing the grip rod 7, the skateboard 204 can be lifted or lowered inside the shell 201 after being gripped, which facilitates the control of whether the tapered column 207 extends out from the top of the shell 201. By providing the anti-slip sleeve 8, the friction force on the outer surface of the grip rod 7 can be increased, thereby improving the comfort of the grip rod 7 when being grasped.

[0025] The inner bottom wall of each storage tube 206 is fixedly connected to a pressure sensor 209, and several identical pressure sensors 209 and alarms 203 are electrically connected to the controller 202 through wires. The outer surface of each hand-tightening bolt 205 is sleeved with an anti-slip soft gasket 9, and the back of each anti-slip soft gasket 9 is in contact with the front of the shell 201. By providing the anti-slip soft gasket 9, it can be sleeved on the outer surface of the hand-tightening bolt 205 and clamped between the hand-tightening bolt 205 and the shell 201, thereby increasing the tightening effect of the hand-tightening bolt 205 on the front of the shell 201, thereby increasing the relative fixing effect of the slide plate 204 and the shell 201.

[0026] A rebound spring 208 is provided inside each storage tube 206, and the two ends of each rebound spring 208 are respectively in contact with the bottom end of the conical column 207 and the upper surface of the pressure sensor 209. A reflector 11 is fixedly connected to the back of the shell 201, and a bottom baffle 10 is fixedly connected to the bottom surface of the guardrail 1. The reflector 11 can increase the reflective effect of the back of the shell 201 at night, thereby playing a role in warning vehicles at night. The bottom baffle 10 can prevent small animals from passing through the bottom of the guardrail 1.

[0027] The working principle of the utility model is: when in use, according to the size of the construction scene, select enough warning fences for splicing. When installing one warning fence, turn one side of the controller 202 toward the construction scene and one side of the reflector 11 toward the outside of the construction. Then use external bolts or fixing pins to cooperate with the mounting plate 5 and the mounting hole 6 and the pre-buried docking structure on the ground for fixing and docking. After installing one warning fence, loosen the two hand-tightening bolts 205. At the same time, after the two anti-slip soft pads 9 are no longer in contact with the front of the shell 201, hold the anti-slip sleeves 8 on the outer surfaces of the two hand grips 7 with both hands, then pull the hand grips 7 upward, and at the same time, multiple storage tubes 206 and the slide plate 204 slide upward inside the shell 201 until the slide plate 204 can no longer rise. Then, hold the hand grip 7 with one hand, and tighten one of the hand-tightening bolts 205 with the other hand. Then, release the hand holding the hand grip 7, and then tighten the other hand-tightening bolt 205 is tightened, and the two anti-skid soft pads 9 are close to the front of the shell 201 to fix the position height of the slide plate 204 inside the shell 201. When someone tries to cross the fence, the sharp conical column 207 will give a preliminary warning to the crosser, and will touch and press down on several of the conical columns 207. The conical column 207 compresses the return spring 208, and the rebound of the return spring 208 squeezes the pressure sensor 209. The pressure sensor 209 transmits the information of the large pressure change in a short period of time to the controller 202, and then the controller 202 controls the alarm 203 to emit an alarm for a period of time to warn the person who wants to cross the fence, and to remind the surrounding construction personnel, reminding the relevant construction personnel or management personnel to come to check and manually intervene. The design of the warning fence for the entire construction project effectively solves the problem of the lack of an anti-crossing alarm structure to prevent outsiders from crossing, which makes it easy for outsiders to cross the fence and pose a safety risk.

[0028] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
