Description

Technical Field

[0001] The invention relates to the technical field of construction site safety helmet monitoring equipment, in particular to a construction site safety helmet wearing identification device. Background Art

[0002] Due to the complex environment of the construction site, no matter who enters the construction site, they must wear a safety helmet as required to enhance safety. In general, construction sites can only rely on management personnel to manually monitor whether workers wear safety helmets, but the turnover of construction site personnel is high, and it is impossible to ensure that all entrants wear safety helmets manually. Although some construction sites have installed safety helmet wearing identification devices at the entrance of the construction site, that is, workers can enter only when they wear safety helmets. However, the recognition effect is average, and workers can pass through with just a safety helmet in their hands, and there is no way to ensure that the workers actually wear it on their heads. At the same time, even if the workers wear safety helmets at the entrance supervision point, there is no guarantee that the workers will always wear safety helmets after entering the construction site. There are many cases where workers take off their safety helmets during work. Summary of the invention

[0003] The purpose of the present invention is to provide a construction site safety helmet wearing identification device to solve the problems raised in the above background technology.

[0010] As a further solution of the present invention: the insulating extrusion block is a convex sphere which is convenient for extrusion.

[0011] As a further solution of the present invention: the construction site safety helmet wearing identification device also includes: an adjustment mechanism for adjusting the position of the remote control switch. The adjustment mechanism includes: an adjustment screw and a strip slide. The adjustment screw is vertically connected to the installation box through a thread.

At the same time, it is ensured that people wearing safety helmets cannot take off their safety helmets after entering the construction site, thus ensuring the safety of people on the construction site.

[0016] The pressure sensing switch set in the hard hat mainly generates induction after the hard hat is worn, so that the first wireless sensing switch in the hard hat and the first wireless key block at the entrance generate response, triggering the opening of the first gate at the entrance. If the hard hat is not worn, the first gate cannot be triggered, so as to achieve the effect of hard hat wearing identification, ensuring that the wearer can enter the construction site. At the same time, when the hard hat is worn passes the entrance position, the anti-drop locking mechanism is triggered, causing the hard hat to be locked on the head. And the hard hat can only be unlocked when the worker passes the exit position of the construction site. That is to ensure that the worker keeps wearing the hard hat within the scope of the construction site.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 6As shown, in an embodiment of the present invention, a construction site safety helmet wearing identification device 100 includes: an entrance frame 10, a first gate 20 and a safety helmet body 30. The first gate 20 is installed at the entrance frame 10, and the safety helmet body 30 is a protective helmet body worn by construction site workers. The construction site safety helmet wearing identification device 100 also includes: an anti-slip locking mechanism 40. The anti-slip locking mechanism 40 includes: a first wireless key block 41, a mounting box 42, a small electric telescopic rod 43, a first wireless induction switch 44, a battery pack 45, a U-shaped sleeve mechanism 46, a remote control switch 47, a shutdown mechanism 48 and a pressure induction switch 49. The mounting box 42 is mounted in pairs on the left and right sides of the safety helmet body 30. The small electric telescopic rod 43 is vertically fixedly connected to the inner side of the mounting box 42, and the upper end of the small electric telescopic rod 43 is a telescopic end. The U-shaped sleeve mechanism 46 is arranged on the lower side of the safety helmet body 30, and when the worker wears the safety helmet body 30, the U-shaped sleeve mechanism 46 is used to cover the chin position of the worker. The U-shaped sleeve mechanism 46 is connected to the telescopic end of the small electric telescopic rod 43. The first wireless key block 41 is installed on the top of the door frame 10. The first wireless induction switch 44 is electrically connected to the extension control circuit of the small electric telescopic rod 43. At the same time, the first wireless key block 41 is wirelessly connected to the first wireless induction switch 44. Here, the first wireless key block 41 and the first wireless induction switch 44 are the one-key start technology of the car in the prior art, that is, after the driver wears a key that can transmit a wireless signal to enter the car, the wireless induction module in the car receives the wireless signal and makes the various components of the entire vehicle enter the power-on ready state. At this time, the key can be directly started, which belongs to the prior art equipment. Therefore, when the safety helmet body 30 is in the area where the first wireless key block 41 is located, the first wireless induction switch 44 receives the wireless signal and makes the extension control circuit of the small electric telescopic rod 43 in the closed circuit run, causing the small electric telescopic rod 43 to extend, causing the U-shaped sleeve mechanism 46 to rise and hit the worker's chin, that is, the safety helmet body 30 is locked to the worker's head to prevent the worker from taking it off in the construction site area. The remote control switch 47 is installed on the inner side of the installation box 42. The remote control switch 47 is connected to the first gate 20 by radio. When the small electric telescopic rod 43 extends upward and causes the U-shaped sleeve mechanism 46 to hit the chin of the worker, the small electric telescopic rod 43 hits the button of the remote control switch 47, and the remote control switch 47 opens the first gate 20, which is convenient for the worker to enter the construction site. The battery pack 45 is installed at the installation box 42, and the battery pack 45 is used to power each power element. The stop mechanism 48 is installed in the middle of the bottom of the U-shaped sleeve mechanism 46. The pressure sensing switch 49 is respectively installed on the inner top and the inner wall of the bottom of the safety helmet body 30. All the extension control circuits of the pressure sensing switches 49, the stop mechanism 48, the first wireless sensing switch 44 and the small electric telescopic rod 43 are connected in series to the same circuit. When the U-shaped sleeve mechanism 46 rises and hits the chin of the worker, the stop mechanism 48 is squeezed, causing the small electric telescopic rod 43 to stop extending in time to avoid squeezing injuries to the worker.Since the pressure sensing switch 49 is distributed at the corresponding position of the inner wall of the helmet body 30, it is ensured that the circuit where the small electric telescopic rod 43 and the first wireless sensing switch 44 are located can enter the power-on ready state only when the helmet body 30 is worn on the worker's head.

[0027] When a worker carries the helmet body 30 and passes through the door frame 10 to enter the construction site, if the helmet body 30 is not worn on the worker's head, the pressure sensing switches 49 connected in series at various positions on the inner wall of the helmet body 30 will not be induced. In this way, the first wireless sensing switch 44 on the helmet body 30 cannot enter the power-on state, and thus cannot receive the trigger wireless signal emitted by the first wireless key block 41. The first gate 10 cannot be opened, that is, the worker cannot enter the construction site. When the helmet body 30 is worn on the worker's head, the pressure sensing switches 49 at various positions on the inner wall of the helmet body 30 will generate induction, and the pressure sensing switches 49 connected in series and generated all make the circuit where the small electric telescopic rod 43 and the first wireless sensing switch 44 are located enter the power-on ready state. At this time, the worker wearing the helmet body 30 is in the door frame 10, and the wireless trigger signal emitted by the first wireless key block 41 is received by the first wireless sensing switch 44. The first wireless induction switch 44 enables the extension control circuit of the small electric telescopic rod 43 to operate, causing the small electric telescopic rod 43 to extend upward, and the U-shaped sleeve mechanism 46 rises and hits the worker's chin. And when the U-shaped sleeve mechanism 46 rises and hits the worker's chin, the stop mechanism 48 is squeezed, causing the small electric telescopic rod 43 to stop extending in time to avoid squeezing injuries to the worker. When the small electric telescopic rod 43 is extended, it hits the button of the remote control switch 47, and the remote control switch 47 opens the first gate 20 to facilitate the workers to enter the construction site. In this way, it is ensured that the U-shaped sleeve mechanism 46 and the safety helmet body 30 firmly encircle the worker's head to prevent the worker from taking it off in the construction site. At the same time, it is ensured that the worker can enter the construction site through the first gate 20 only when the safety helmet body 30 is worn, and cannot pass if it is not worn, that is, the safety helmet wearing recognition effect is achieved.

[0028] The U-shaped sleeve mechanism 46 includes: a U-shaped locking rod 461 and a lifting column 462. The lifting column 462 slides vertically and penetrates to the bottom of the installation box 42. The upper end of the lifting column 462 is fixedly connected to the telescopic end of the small electric telescopic rod 43. The U-shaped locking rod 461 is movably connected to the lower end of the lifting column 462 through a hinge. Since the U-shaped locking rod 461 and the lifting column 462 are movably connected, it is convenient for the U-shaped locking rod 461 to rotate and adjust the angle to avoid hindering the safety helmet body 30 from being put on the worker's head. After the safety helmet body 30 is worn, the U-shaped locking rod 461 is rotated to the same straight line position as the lifting column 462. At this time, the U-shaped locking rod 461 is on the lower side of the worker's chin, and the small electric telescopic rod 43 is extended, causing the lifting column 462 to drive the U-shaped locking rod 461 to rise and insert into the installation box 42. When the upper end of the U-shaped locking rod 462 is inserted into the installation box 42, the U-shaped locking rod 462 can only be raised and lowered in the vertical direction and cannot be rotated, so that the U-shaped locking rod 462 can be firmly circled at the chin position of the worker.

[0029] The U-shaped sleeve mechanism 46 also includes an elastic rubber stopper 463 for limiting the position. The elastic rubber stopper 463 is arranged in pairs at the front and rear sides of the connection end of the U-shaped locking rod 462 and the lifting column 462. The elastic rubber stopper 463 is used to keep the U-shaped locking rod 462 in a vertical position. At the same time, since the elastic rubber stopper 463 is squeezed and deformed, it is convenient for the U-shaped locking rod 462 to rotate and adjust the position, and it is convenient for the helmet body 30 to be worn.

[0030] The U-shaped sleeve mechanism 46 further includes a cotton sleeve 464. The cotton sleeve 464 is sleeved onto the U-shaped locking rod 462. The cotton sleeve 464 is used to increase the comfort of the U-shaped locking rod 462 in contact with the worker's chin.

[0031] The stopping mechanism 48 includes: an installation cavity 481, an insulating extrusion block 482, a movable conductive block 483, a connecting spring 484 and a fixed conductive block 485. The installation cavity 481 is opened to the bottom of the U-shaped locking rod 462. The insulating extrusion block 482 is movably engaged with the port of the installation cavity 481. The movable conductive block 483 is fixedly connected to the lower side of the insulating extrusion block 482. The connecting spring 484 is connected between the movable conductive block 483 and the installation cavity 481. The fixed conductive block 481 is fixedly connected to the upper side of the inner wall of the installation cavity 481. The movable conductive block 481 and the fixed conductive block 485 are electrically connected in series through wires to the circuit connected to the extension control circuit of the first wireless induction switch 44 and the small electric telescopic rod 43. When the U-shaped locking rod 462 rises and hits the chin of the worker, the insulating extrusion block 482 on the U-shaped locking rod 462 slides into the installation cavity 481 due to extrusion. The movable conductive block 481 is separated from the fixed conductive block 485, thereby causing the small electric telescopic rod 43 and the extension circuit triggered by the first wireless induction switch 44 to be disconnected and stopped.

[0032] The insulating extrusion block 482 is a convex sphere for easy extrusion.

[0033] The construction site safety helmet wearing identification device 100 also includes: an adjustment mechanism 50 for adjusting the position of the remote control switch 47. The adjustment mechanism 50 includes: an adjustment screw 51 and a strip slide 52. The adjustment screw 51 is vertically connected to the bottom of the installation box 42 through a thread. The upper end of the adjustment screw 51 is rotatably connected to the housing of the remote control switch 47 through a bearing. The strip slide 52 is vertically opened to the left inner wall of the installation box 42. The remote control switch 47 is slidably connected to the strip slide 52. According to the different extension positions of the small electric telescopic rod 43 after each person wears a safety helmet, the adjustment screw 51 is rotated to drive the remote control switch 47 to slide up and down along the strip slide 52 to adjust the position relative to the telescopic end of the small electric telescopic rod 43.

[0034] The adjustment mechanism 50 further includes: a slot body 53 and a closing cover 54. The slot body 53 is opened to the outer wall of the mounting box 52 where the lower end of the adjusting screw 51 is located. The closing cover 54 is fixedly connected to the slot body 53 by screws, and the closing cover 54 is used to close the space where the adjusting end of the adjusting screw 51 is located to prevent the adjusting end of the adjusting screw 51 from being accidentally adjusted and affecting the position of the remote control switch 47. When adjustment is required, the closing cover 54 can be removed.

[0035] The construction site safety helmet wearing identification device 100 also includes: a laser sensor switch 60 for closing the first gate 20. The laser sensor switch 60 is electrically connected to the closing control circuit of the first gate 20. The laser sensor switch 60 is installed at the exit side wall of the door frame 10. When a worker wearing a safety helmet passes through the first gate 20, the first Jigang sensor switch 60 generates an induction to close the first gate 20.

[0036] The construction site safety helmet wearing identification device 100 also includes: an exit unlocking mechanism 70. The exit unlocking mechanism 70 includes: a second gate 71, a door opening switch 72, a second wireless key block 73, a second wireless induction switch 74 and an exit frame 75. The second gate 71 is installed at the exit frame 75. The door opening switch 72 is installed at the exit frame 75, and the door opening switch 72 is located on the side of the exit frame 75 in the construction site area. The door opening switch 72 is electrically connected to the door opening control circuit of the second gate 71. The second wireless key block 73 is installed at the exit frame 75, and the second wireless key block 73 is at the exit end of the exit frame 75. The second wireless induction switch 74 is electrically connected to the contraction control circuit of the small electric telescopic rod 43. When the worker leaves the construction site, the second gate 71 is opened by the door opening switch 72. Then walk out of the construction site through the second gate 71, and the wireless signal transmitted by the second wireless key block 73 is received by the second wireless induction switch 74. The second wireless induction switch 74 causes the small electric telescopic rod 43 to retract, causing the U-shaped locking rod 461 to descend, making it easier for the worker to take off the safety helmet body 30 .
