DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0036] like Figure 1 and 2 As shown, a high-altitude anti-fall intelligent locking hook includes: a main hook 1, an auxiliary hook 2 and a safety rope 3; the main hook 1 and the auxiliary hook 2 are connected by the safety rope 3, the main hook 1 and the auxiliary hook 2 are respectively connected to the fixed component and the operator, and the main hook 1 and the auxiliary hook 2 are also provided with a control component, the control component includes: a control box 4, a safety rod locking mechanism 5, a locking sensor component 6 and an unlocking sensor component 7, the safety rod locking mechanism 5 is arranged in the control box 4, the locking sensor component 6 is arranged at the hook ring 12 at the end of the main hook 1 and the auxiliary hook 2, and contacts with the fixed component, and the unlocking sensor component 7 is arranged at the hook handle 13 of the main hook 1 and the auxiliary hook 2, and contacts with the safety rod 16 on the hook handle 13.

[0037] The main hook 1, the auxiliary hook 2 and the safety rope 3 are used to connect the construction workers and the fixed components at the construction site to protect the construction workers.

[0038] The control component is used to detect the hanging status of the main hook 1 and the auxiliary hook 2. The control component feedbacks and controls the locking and unlocking of the main hook 1 and the auxiliary hook 2 according to the hanging status of the main hook 1 and the auxiliary hook 2. The setting of the control component is convenient for detecting the use status of the device, and controls the locking of the main hook 1 and the auxiliary hook 2 according to the status to prevent construction personnel from operating in violation of regulations.

[0039] The control box 4 is used for installing the safety lever locking mechanism 5, the control panel 43 and their accessories, and also protects the safety lever locking mechanism 5, the control panel 43 and their accessories, enhances their weather resistance, makes them suitable for use in complex environments, and increases their service life.

[0040] The safety rod locking mechanism 5 is used to add physical locking to the main hook 1 and the auxiliary hook 2, realizing the compulsory locking function of the hook, and truly making it impossible for the wearing operator to unhook illegally, thereby ensuring the life safety of the construction workers.

[0041] The locking sensor assembly 6 is used to monitor the use status of the hook through the locking sensor and transmit the monitored data to the control box 4, so that the control box 4 can control the unlocking and locking of the hook.

[0042] The unlocking sensor assembly 7 is used to unlock in an emergency situation, making it easier for construction workers to handle emergencies.

[0043] like Figure 2 and 3 As shown, the main hook 1 and the auxiliary hook 2 are both made of stainless steel, and the two are completely identical in structure. The main hook 1 and the auxiliary hook 2 both include a hook body 11 .

[0044] The hook body 11 includes: a hook ring 12, a hook handle 13, a locking rod 15 and a safety rod 16. The cross-section of the locking rod 15 is U-shaped, and both ends of the locking rod 15 are open. One end of the locking rod 15 is hinged to the hook handle 13 through a pin, and the other end is overlapped on the end of the hook ring 12. When the pin-connected end of the locking rod 15 rotates around the pin, the other end can release the overlap with the end of the hook ring 12, thereby realizing the hooking and taking.

[0045] In order to limit the rotation of the locking rod 15, a safety rod 16 is hinged on the hook handle 13 by a pin. The safety rod 16 contacts the locking rod 15. When the safety rod 16 is pressed, the safety rod 16 rotates along the pin to release the limit of the locking rod 15, and the locking rod 15 can rotate at this time.

[0046] In order to reset the locking rod 15 and the safety rod 16 after rotation, a spring is installed between the safety rod 16 and the hook handle 13, and between the locking rod 15 and the hook handle 13, respectively. The spring between the safety rod 16 and the hook handle 13 is named the second reset spring 18, and the spring between the locking rod 15 and the hook handle 13 is named the first reset spring 17.

[0047] In order to facilitate the installation of the safety rope 3 , a circular through hole is opened at the end of the hook handle 13 , and the through hole is named as a safety rope fixing hole 14 . The safety rope 3 passes through the safety rope fixing hole 14 and is fixed on the hook handle 13 .

[0048] In order to facilitate unlocking in an emergency, a rectangular piece is protruded outwardly on the end surface of the locking rod 15 away from the control box 4. This rectangular piece is named the unlocking sensor pressing piece 19, and the unlocking sensor pressing piece 19 is in contact with the unlocking sensor.

[0049] like Figure 2 , 4 As shown in 5, the setting of the control box facilitates the installation of the control panel and its accessories, and is convenient for protecting them to ensure the stable operation of the device. The control box 4 includes an upper box body 41 and a lower box body 42. The upper box body 41 and the lower box body 42 are hollow plastic boxes made of high-density polyethylene (HDPE) with strong weather resistance. The upper box body 41 and the lower box body 42 are connected together by screws.

[0050] The upper box body 41 and the lower box body 42 are integrally clamped at the hook handle 13 in the hook body 11, and the hook handle 13 is given way at the clamping point. In order to facilitate the safety rope 3 to be tied to the safety rope fixing hole 14 on the hook handle 13, a circular through hole is opened on the surface of the upper box body 41 and the lower box body 42 perpendicular to the upper box body 41 and the lower box body 42, respectively. This through hole is named as a functional hole 410. The functional hole 410 corresponds to the position of the safety rope fixing hole 14, and the functional hole 410 and the safety rope fixing hole 14 have the same inner diameter. The safety rope 3 can pass through the functional hole 410 and the safety rope fixing hole 14 in sequence for fixation.

[0051] In order to improve the stability of fixation and prevent the safety rope 3 from damaging the control box 4 during use, a circular tube is sleeved in the functional hole 410, and this tube is named a protective ring 411. The outer diameter of the protective ring 411 is the same as the inner diameter of the functional hole 410. The protective ring 411 passes through the functional hole 410 and is inserted into the safety rope fixing hole 14. The safety rope 3 passes through the protective ring 411 and is connected to the hook body 11.

[0052] In order to improve the stability of the fixing of the protective ring 411, the protective ring 411 can be made of two flange sleeves. The protective ring 411 is fixed to the hook handle 13 of the hook body 11 by screws. It is stable to use and prevents the safety rope 3 from damaging the control box 4 during use. The setting of the protective ring 411 is convenient for protecting the control box 4 and preventing the safety rope from damaging the control box.

[0053] In order to facilitate the installation of the safety rod locking mechanism 5, an "L"-shaped baffle is protruding perpendicular to the inner wall at one end of the lower box body 42 near the safety rod 16. The baffle and the two inner side walls of the lower box body 42 form a cavity with an open upper end. This cavity is named the locking mechanism installation cavity 45. The safety rod locking mechanism 5 is installed in this locking mechanism installation cavity 45. In order to facilitate the safety rod locking mechanism 5 to limit the position of the safety rod 16, a clearance opening is opened on the inner side wall of the locking mechanism installation cavity 45 corresponding to the opening at the end of the safety rod 16. The locking rod 53 in the safety rod locking mechanism 5 can pass through this clearance opening and be inserted into the safety rod 16.

[0054] In order to facilitate the control of the extension and retraction of the safety bar locking mechanism 5, and thereby limit the locking of the locking rod 15 by the safety bar 16 and receive and send transmission signals, a control board 43 and a control power supply 44 for powering the control board 43 are also installed in the control box 4. The control board 43 is installed in the upper box body 41 and contacts the hook handle 13. The control power supply 44 is arranged in the lower box body 42 and contacts the hook handle 13. The control power supply 44 and the control board 43 are connected by a wire to power the control board 43.

[0055] In order to facilitate the monitoring of usage and usage status, the control panel 43 is also provided with a temperature sensor, a height sensor and a posture sensor. These sensors are existing products and can be used directly. The setting of the sensor enhances the perception function of the device, facilitates the collection of parameters such as the working height, ambient temperature, posture, etc. of the construction personnel, and provides richer data support for safe operations.

[0056] In order to facilitate the startup and functional operation of the device, a function switch is installed on the upper box body 41, and the installation location is waterproofed. The function switch is connected to the control board 43, and the function switch can control the switch and function selection of the device.

[0057] In order to improve weather resistance and adapt to complex environments, the upper box body 41 and the lower box body 42 are sealed and waterproofed at the connection.

[0058] In order to improve the overall endurance of the equipment, increase the usage time, and ensure that the equipment can be used normally after the control power supply 44 is used up, an expansion power supply installation groove 47 is convexly provided on the side of the control box 4. The expansion power supply installation groove 47 is a groove with a "U"-shaped cross-section. A power supply contact connected to the control board 43 is fixed in the expansion power supply installation groove 47. The expansion power supply 46 can be plugged into the expansion power supply installation groove 47 through the expansion power supply installation groove 47 and connected to the power supply contact to power the entire equipment. The setting of the expansion power supply 46 improves the endurance of the device, and when the equipment is out of power, the equipment can be powered by replacing the expansion power supply 46, which is easy to use.

[0059] When the control power supply 44 has sufficient power and the expansion power supply 46 is not needed, in order to close the expansion power supply installation slot 47, a plastic slot cover 48 is inserted into the expansion power supply installation slot 47. The expansion power supply installation slot 47 is closed by the slot cover 48, effectively preventing foreign matter and rainwater from entering the expansion power supply installation slot 47 and causing damage to the equipment.

[0060] In order to provide safety warnings to construction workers, a speaker 49 is also installed on the control panel 43. When it is detected that there is a risk in the use of safety belts by construction workers, the speaker 49 can issue a safety reminder.

[0061] like Figure 5 and 6 As shown, the safety rod locking mechanism 5 includes: a motor 51, a screw rod 52, a connecting piece 56 and a locking rod 53. The motor 51 is connected to the screw rod 52, and the screw rod 52 is connected to the locking rod 53. The locking rod 53 can be controllably extended or retracted into the control box 4 under the action of the motor 51 and the screw rod 52. The extended locking rod 53 is inserted into the safety rod 16 to limit the unlocking of the safety rod 16. Such a setting adds a physical lock to the main hook and the auxiliary hook to realize the forced locking function of the hook, so that the wearing operator cannot illegally unhook the hook, thereby ensuring the life safety of the construction workers. One end of the connecting piece 56 is connected to the screw rod 52, and the other end of the connecting piece 56 is inserted into the locking rod 53. The connecting piece 56 can be driven to move through the screw rod 52, thereby driving the locking rod 53 to move as a whole.

[0062] The motor 51 is an existing micro motor. In order to facilitate the installation of the screw rod 52 and the connection between the screw rod 52 and the motor 51, the screw rod 52 is installed in a rectangular screw rod mounting box 55. The screw rod mounting box 55 is a rectangular hollow plastic box. The screw rod 52 passes through the screw rod mounting box 55. A gear 54 is fixed at the end of the screw rod 52. At the same time, a gear 54 is also fixed on the main shaft of the motor 51. The two gears 54 are meshed, and the motor 51 and the gear 54 can drive the screw rod 52 to rotate as a whole.

[0063] The connecting piece 56 is a plastic block with a "T"-shaped cross-section. A circular mounting hole is provided at the junction of the horizontal piece and the vertical piece of the connecting piece 56. A screw sleeve is inserted into the mounting hole. The connecting piece 56 is installed on the screw 52 through the screw sleeve. In order to facilitate the installation and movement of the connecting piece 56, a corresponding long strip-shaped clearance hole is provided on the screw mounting box 55. Under the action of the screw 52, ​​the connecting piece 56 can move linearly.

[0064] The locking rod 53 is a plastic rod with a rectangular cross-section. The cross-sectional area of ​​the locking rod 53 is the same as the cross-sectional area of ​​the locking mechanism mounting cavity 45. A rectangular hole is provided on the surface of the locking rod 53, and this hole is named a connecting socket 57. The end of the connecting piece 56 can be inserted into this connecting socket 57. The rotation of the screw rod 52 can drive the locking rod 53 to move. When the locking rod 53 extends from the control box 4 and is inserted into the safety rod 16, the safety rod 16 cannot rotate, and the locking rod 15 cannot be opened at this time.

[0065] like Figure 1 , 7 As shown in 8, the setting of the locking sensor component is convenient for locking the main hook and the auxiliary hook according to the construction situation to ensure the safety of the construction workers. The locking sensor component 6 includes a locking sensor upper mounting plate 61 and a locking sensor lower mounting plate 62. The locking sensor upper mounting plate 61 and the locking sensor lower mounting plate 62 are detachably mounted on both sides of the hook ring 12 on the hook body 11 by screws.

[0066] The locking sensor upper mounting piece 61 and the locking sensor lower mounting piece 62 are arc-shaped plastic cards made of HDPE material. The locking sensor upper mounting piece 61 and the locking sensor lower mounting piece 62 can be clamped at the hook ring 12 of the hook body 11, and the two are fixedly connected with screws.

[0067] In order to improve the sealing of the connection and increase the service life, a groove is formed on the contact surface of the locking sensor upper mounting plate 61, which is perpendicular to the contact surface and is named as a sealing groove 63. At the same time, a sealing boss and a sealing groove 63 are also provided on the corresponding surface of the locking sensor lower mounting plate 62. The setting of the sealing groove 63 and the sealing boss can improve the sealing of the contact between the two, prevent the entry of rainwater and dust, and increase the service life. Such a setting enhances the sealing of the locking sensor upper mounting plate 61 and the locking sensor lower mounting plate 62, prevents the entry of external debris and rainwater, improves the overall weather resistance, and while enhancing the service life, it also ensures the normal and stable use of the device in harsh environments.

[0068] In order to facilitate the installation of the sensor, a rectangular groove is provided on the inner arc surface of the locking sensor upper mounting plate 61 and the locking sensor lower mounting plate 62, perpendicular to the inner arc surface. This groove is named the sensor mounting groove 64, and the locking sensor is installed in this sensor mounting groove 64.

[0069] When the hook is working, in order to facilitate the triggering of the locking sensor, a locking sensor contact 65 made of rubber is installed on the sensor mounting groove 64. The locking sensor contact 65 is semi-arc-shaped. The locking sensor contact 65 is glued to the inner arcs of the locking sensor upper mounting piece 61 and the locking sensor lower mounting piece 62 by glue to ensure the sealing. The locking sensor contact 65 is in contact with the locking sensor. When the hook is hung on a fixed component or a construction worker, the locking sensor contact 65 is subjected to force to trigger the locking sensor.

[0070] The setting of the unlocking sensor component facilitates unlocking in an emergency situation. The unlocking sensor component 7 includes an unlocking sensor upper mounting plate 71 and an unlocking sensor lower mounting plate 72. The unlocking sensor upper mounting plate 71 and the unlocking sensor lower mounting plate 72 are installed on both sides of the hook handle 13 by screws, and one end overlaps with the mounting plate on the locking sensor component 6.

[0071] The unlock sensor upper mounting piece 71 and the unlock sensor lower mounting piece 72 are both made of HDPE material and are long plastic sheets with an "L"-shaped cross frame surface. The longer cross plates of the unlock sensor upper mounting piece 71 and the unlock sensor lower mounting piece 72 are placed on the hook handle 13 and cover the top of the safety bar 16. The setting of the unlock sensor upper mounting piece 71 and the unlock sensor lower mounting piece 72 cannot affect the normal rotation of the safety bar 16, and there is no position interference between them.

[0072] A circular mounting hole is provided on the vertical plate with smaller size of the unlocking sensor upper mounting piece 71 and the unlocking sensor lower mounting piece 72, and the unlocking sensor upper mounting piece 71 and the unlocking sensor lower mounting piece 72 are fixed together by screws through the circular mounting holes. In order to prevent the unlocking sensor upper mounting piece 71 and the unlocking sensor lower mounting piece 72 from falling off, the unlocking sensor upper mounting piece 71 and the unlocking sensor lower mounting piece 72 and the locking sensor upper mounting piece 61 and the locking sensor lower mounting piece 62 can be connected together, that is, the unlocking sensor upper mounting piece 71 and the locking sensor upper mounting piece 61 are integrally formed, and the unlocking sensor lower mounting piece 72 and the locking sensor lower mounting piece 62 are integrally formed.

[0073] In order to facilitate the rotation of the safety bar 16, a clearance hole 73 is opened on the unlocking sensor upper mounting plate 71 and the unlocking sensor lower mounting plate 72 near the safety bar 16. At the same time, an unlocking sensor is fixed on the unlocking sensor upper mounting plate 71 near the clearance hole 73. The clearance hole 73 corresponds to the position of the safety bar 16. The unlocking sensor contacts the unlocking sensor pressing plate 19 on the safety bar 16, and the unlocking sensor is always in a triggered state when the safety bar 16 is normally limited.

[0074] In order to facilitate the release of the contact between the unlock sensor pressing piece 19 and the unlock sensor, the size of the locking rod 53 is slightly smaller than the size of the opening of the locking rod 53 .

[0075] The unlocking sensor and the locking sensor are existing contact switches and can be purchased and used directly.

[0076] Regarding the distribution of the wiring on the sensor, in order to improve the overall weather resistance of the device, the wiring connected to the unlocking sensor and the locking sensor are arranged on the inner side of the locking sensor mounting plate 61 and the unlocking sensor mounting plate 71 without contacting the outside world.

[0077] The use process of this embodiment: In this embodiment, the main hook 1 and the auxiliary hook 2 are bound to the identity of the construction personnel and can be adjusted through the background. When in use, the construction personnel first turn on the switch, at which time the safety bar locking mechanism 5 is not activated. The construction personnel hang the auxiliary hook 2 on the safety belt on their body, and then arrive at the work site, and then hang the main hook 1 on the fixed component. At this time, the control panel 43 simultaneously receives the signals transmitted by the locking sensors on the main hook 1 and the auxiliary hook 2. At this time, the safety bar locking mechanism 5 on the main hook 1 and the auxiliary hook 2 is activated to lock the safety bar 16 to prevent the construction personnel from illegally unlocking it;

[0078] When the construction personnel change positions and need to unlock the main hook 1, they press the safety lever 16 twice in succession, and the unlocking sensor pressure piece 19 connected to the safety lever 16 continuously disconnects from the unlocking sensor and sends an unlocking request to the control board 43. At this time, the control board 43 detects the connection status of the auxiliary hook 2. If the auxiliary hook 2 is connected normally, the locking rod 53 is retracted, and the main hook 1 can be opened. If the main hook 1 is not re-hooked within 20 seconds, the main hook 1 will issue a reminder to remind the construction personnel. If the main hook 1 is not re-hooked within 1 minute, the control board 43 will send a reminder to the system background to remind the personnel to check.

[0079] When an emergency situation requires unlocking, the safety lever 16 is continuously pressed for 10 seconds to send a forced unlocking request to the control panel 43. At this time, the locking lever 53 is retracted, the main hook 1 can be opened, and the control panel 43 sends a reminder to the system background to remind personnel to handle it.
