Description

Technical Field

[0001] This invention relates to the field of safety devices for tower climbing operations, and in particular to a foot-pronged anti-slip and anti-fall locking device for tower climbing and its usage method. Background Technology

[0002] Currently, fall protection methods used for tower climbing operations include five-point harnesses with double hooks, safety rings mounted on foot spikes, fall arrest rails, and backup safety ropes for drones. Each of these devices has drawbacks in terms of flexibility, safety, and maintenance costs. For example, the most commonly used fall protection device is the safety harness fall arrest ring; its specific structure can be found at [website address missing]. https: / / tv.cctv.com / 2019 / 10 / 07 / VIDEc6kxb9VL4wXHTd7c5F to191007.shtml ;

[0003] The safety ring for fall protection is simple in structure. When climbing the tower, the worker holds the safety ring with one hand and secures it to the tower's foot spikes via a rope loop. In the event of a fall, gravity tightens the rope loop, locking the foot spikes in place. However, this method has certain safety hazards. It cannot be ruled out that during a fall, the safety ring might slip off the foot spike due to the force of the fall, thus failing to provide protection. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides a foot-pronged anti-slip and anti-fall locking device for tower climbing and its usage method. This solves the problem that existing safety belt fall protection rings may slip off the foot prongs due to force during a fall, thus failing to provide protection.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A foot-pronged tower climbing anti-slip and anti-fall locking device is provided, which includes a locking body, a warning system at the top of the locking body, a locking anti-slip track in the middle, and a bottom for fixing and connecting the safety belt connecting rope.

[0007] The warning system is used to detect the connection status between the locking body and the tower foot nail, and issue a warning reminder based on the connection status.

[0008] A locking slider is vertically slidably disposed within the locking slide, and a locking sleeve is vertically slidably connected to the outside of the locking body. At least one first groove and one second groove are provided through the outer circumference of the locking sleeve. The first groove is located at the top of the second groove. The first groove has an "I" shaped structure. A first guide post is slidably disposed within the first groove and is fixedly connected to the outer wall of the locking slider.

[0009] The second groove includes a vertical channel, and a left horizontal channel and a right horizontal channel are respectively connected to both sides of the vertical channel; a second guide post is provided on the outer wall of the locking body, which is located in the second groove and slides in conjunction with the second groove.

[0010] Furthermore, the middle and bottom of the locking body are hollow cylindrical structures, and an auxiliary locking spring is provided inside the locking body. The bottom end of the auxiliary locking spring is fixed to the bottom of the locking body by an internal hexagon set screw, and the top end of the auxiliary locking spring is in close contact with the lower end face of the locking slider. In the above technical solution, the auxiliary locking spring always applies a vertically upward thrust to the locking slider, which helps the locking slider slide up and down more easily, and is more conducive to the worker's one-handed operation of the locking device during construction.

[0011] Furthermore, the bottom of the buckle body is provided with a pin and a notch in the shape of an "I". The pin is horizontally positioned and passes through the bottom of the buckle body and the notch, and the end of the pin is provided with a cotter pin. The safety belt connecting rope passes through the notch and is fixed to the pin. The pin is used to fix the safety belt connecting rope, and the cotter pin is provided to prevent the pin from falling off the buckle body.

[0012] Furthermore, both the top of the locking slide and the top of the locking slider have a semi-circular curved surface structure. The beneficial effects of the above technical solution are: it allows the top of the locking slide and the top of the locking slider to fit more closely with the tower anchor, increasing the contact area between the locking slide and the locking slider and the tower anchor, thus enhancing the stability of the connection.

[0013] Furthermore, the warning system includes a circuit box fixedly connected to the top of the latch body, and the circuit box can be threadedly connected to the top of the latch body via a threaded sleeve.

[0014] The circuit box is equipped with a cover on the top. Inside the circuit box are a power module, a circuit board, a contact switch and an alarm that are electrically connected to each other. The circuit board integrates a microcontroller and a wireless transceiver module electrically connected to the microcontroller. The bottom of the contact switch is equipped with a top rod. The top of the top rod is connected to the contact switch through a switch spring, and the bottom of the top rod passes through the circuit box and is located in the locking slide.

[0015] The warning system operates on the following principle: When the locking slider and the locking body are clamped onto the tower foot spikes, the tower foot spikes contact the bottom of the top rod, causing the top rod to move upward and triggering the contact switch. A microcontroller collects and processes the status information of the contact switch, and a wireless transceiver module transmits the processed data to the user terminal. Specifically, the microcontroller may include an ADC module, a CPU module, and a serial port module connected in sequence. The microcontroller converts the analog signal from the switch into a digital signal via the ADC module, processes the data via the CPU module, and then transmits it to the user terminal via the wireless transceiver module using a point-to-point configuration through the serial port module. The user terminal receives the data via its own wireless transceiver module, processes it through a data analysis program to determine the connection status between the locking body and the tower foot spikes, and controls the alarm to issue the corresponding warning. The microcontroller can be a Teensy 4.1 microcontroller. The wireless transceiver module can be an XBEE module. The power supply module provides power to all electrical components of the warning system.

[0016] Furthermore, the alarm includes a light alarm and a sound alarm.

[0017] Furthermore, there are two of each of the first and second grooves; both the first and second grooves are symmetrically arranged about the axis of the latch body.

[0018] Furthermore, the contact switch is a normally open switch.

[0019] This invention also provides a method for using a foot-pile type anti-slip and anti-fall locking device for tower climbing. Two locking devices are connected to the safety harness rope worn by the worker. When working at a fixed position on the tower, the locking sleeve is slid downwards to move the locking slider to the lowest position of the locking track. After the locking track passes through the tower foot spike, the locking sleeve is slid upwards to move the locking slider upwards, so that the locking slider and the locking body tightly hold the tower foot spike. The locking sleeve is rotated to allow the second guide post to engage with the left or right horizontal channel, achieving mechanical self-locking and ensuring that the locking slider will not slip during construction, thus achieving a stable connection between the locking device and the tower foot spike. A warning system detects the connection status between the locking body and the tower foot spike. When both locking devices are not locked, the warning system alarms.

[0020] When workers are climbing the tower, they use two locking devices alternately to keep one locking device connected to the tower footing at all times. The unlocking process between the locking device and the tower footing is as follows: rotate the locking sleeve so that the vertical channel in the second groove is aligned with the second guide post, and then slide the locking sleeve downward. The locking slider is driven to slide downward by the cooperation of the first guide post and the first groove, thereby releasing the secure connection between the locking device and the tower footing.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The anti-slip and anti-fall locking device for tower climbing with foot nails in this solution is fixedly connected to the tower foot nails and is designed with a mechanical self-locking structure, which ensures that the locking device and the tower foot nails will not be separated from the tower foot nails due to accidental contact, which helps to reduce the accident rate caused by workers falling from heights, protect the lives and health of workers, and improve the safety level of the workplace.

[0022] 2. The foot-pronged tower climbing anti-slip and anti-fall locking device in this solution is equipped with a warning system. The warning system detects the connection status between the locking body and the tower foot prongs and issues a warning reminder based on the connection status, which further improves safety and avoids the shortcomings of traditional methods.

[0028] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0029] like Figures 1-3As shown, the present invention provides a foot-pronged tower climbing anti-slip and anti-fall locking device (hereinafter referred to as the locking device). The locking device includes a locking body 1, a warning system 2 is provided at the top of the locking body 1, a locking anti-slip track 5 is provided in the middle, and the bottom is used to fix and connect the safety belt connecting rope 3.

[0030] The warning system 2 is used to detect the connection status between the locking body 1 and the tower foot nail 4, and issue a warning reminder based on the connection status.

[0031] A locking slide 5 is provided through the middle of the locking body 1. A locking slider 6 is vertically slidably arranged in the locking slide 5. A locking sleeve 7 is vertically slidably connected to the outside of the locking body 1. At least one first groove 8 and one second groove 9 are provided through the outer circumference of the locking sleeve 7. The first groove 8 is located at the top of the second groove 9. The first groove 8 has an "I" shaped structure. A first guide post 10 is slidably arranged in the first groove 8 and fixedly connected to the outer wall of the locking slider 6.

[0032] Preferably, the top of the locking slide 5 and the top of the locking slider 6 both have a semi-circular curved surface structure. The beneficial effect of the above technical solution is that it makes the top of the locking slide 5 and the top of the locking slider 6 fit more closely with the tower foot nail 4, increases the contact area between the locking slide 5 and the locking slider 6 and the tower foot nail 4, and enhances the stability of the connection.

[0033] The second groove 9 includes a vertical channel 91, and a left horizontal channel 92 and a right horizontal channel 93 are respectively connected to both sides of the vertical channel 91; a second guide post 11 is provided on the outer wall of the locking body 1, which is located in the second groove 9, and the second guide post 11 is slidably engaged with the second groove 9.

[0034] When fixing the entire locking device, the locking slider 6, through the cooperation of the first guide post 10 and the first groove 8, realizes the transmission between the locking sleeve 7 and the locking slider 6. Sliding the locking sleeve 7 downwards drives the locking slider 6 to the lowest position of the locking slide 5. After the locking slide 5 passes through the tower foot nail 4, sliding the locking sleeve 7 upwards drives the locking slider 6 upwards, so that the locking slider 6 and the locking body 1 tightly hold the tower foot nail 4. Rotating the locking sleeve 7 allows the second guide post 11 to cooperate with the left horizontal channel 92 or the right horizontal channel 93, achieving mechanical self-locking and ensuring that the locking slider 6 will not slip during construction, thus achieving a stable connection between the locking device and the tower foot nail 4. In this embodiment, by changing the length of the locking slide 5 to adapt to different models of tower foot nails 4, stable fixing of tower foot nails 4 at different positions on the tower can be achieved.

[0035] The unlocking process between the locking device and the tower foot nail 4 is as follows: rotate the locking sleeve 7 so that the vertical channel 91 in the second groove 9 is aligned with the second guide post 11, and then slide the locking sleeve 7 downward. The locking slider 6 is driven to slide downward by the cooperation of the first guide post 10 and the first groove 8, thereby releasing the secure connection between the locking device and the tower foot nail 4.

[0036] The proposed solution includes a foot-peg type anti-slip and anti-fall locking device for tower climbing. The locking body 1 is fixedly connected to the tower foot peg 4 and is designed with a mechanical self-locking structure. This ensures that the locking device will not detach from the tower foot peg 4 due to accidental contact, which helps to reduce the accident rate caused by workers falling from heights, protect workers' lives and health, and improve workplace safety.

[0037] Specifically, the middle and bottom of the locking body 1 are hollow cylindrical structures. An auxiliary locking spring 12 is provided inside the locking body 1. The bottom end of the auxiliary locking spring 12 is fixed to the bottom of the locking body 1 by an internal hexagon set screw 13, and the top end of the auxiliary locking spring 12 is in close contact with the lower end face of the locking slider 6. In the above technical solution, the auxiliary locking spring 12 always applies a vertical upward thrust to the locking slider 6, which helps the locking slider 6 to slide up and down more easily. This is more conducive to workers operating the locking device with one hand during construction. It also allows the locking slider 6 to have a continuous upward movement trend, clamping the tower anchor 4 between the locking slide 5 and the locking slider 6, preventing the entire gripping device from falling off.

[0038] Preferably, but not limited to, as a specific arrangement for fixing the safety belt connecting rope 3 to the bottom of the buckle body 1, the bottom of the buckle body 1 is provided with a pin 14 and a notch 15 in the shape of an "I". The pin 14 is horizontally arranged and passes through the bottom of the buckle body 1 and the notch 15, and the end of the pin 14 is provided with a cotter pin 16; the safety belt connecting rope 3 passes through the notch 15 and is fixed to the pin 14. The function of the pin 14 is to fix the safety belt connecting rope 3, and the cotter pin 16 is provided to prevent the pin 14 from falling off the buckle body 1.

[0039] As a specific configuration of the warning system 2, the warning system 2 includes a circuit box 21 fixedly connected to the top of the latch body 1. The circuit box 21 can be threadedly connected to the top of the latch body 1 via a threaded sleeve 17.

[0040] The circuit box 21 is topped with a cover. Inside the circuit box 21 are electrically connected power modules, circuit boards 22, contact switches 23, and alarms. The circuit board 22 integrates a microcontroller and a wireless transceiver module electrically connected to the microcontroller. The bottom of the contact switch 23 has a push rod 24. The top of the push rod 24 is connected to the contact switch 23 via a switch spring 25, and the bottom of the push rod 24 passes through the circuit box 21 and is located within the locking slide 5. The alarm includes a light alarm and a sound alarm. The contact switch 23 is a normally open switch. Specifically, the microcontroller can be a Teensy 4.1 microcontroller. The wireless transceiver module can be an XBEE module. The power module supplies power to all electrical components of the warning system 2.

[0041] like Figure 4 As shown, the principle of the warning system 2 is as follows: When the locking slider 6 and the locking body 1 are clamped onto the tower foot nail 4, the tower foot nail 4 contacts the bottom of the top rod 24, causing the top rod 24 to move upward and triggering the contact switch 23. The microcontroller is used to collect and process the status information of the contact switch 23, and the wireless transceiver module is used to transmit the processed data information from the microcontroller to the user terminal. Specifically, the microcontroller may include an ADC module, a CPU module, and a serial port module connected in sequence. The microcontroller converts the analog signal of the switch into a digital signal through the ADC module, and then performs data processing through the CPU module. After point-to-point configuration using the serial port module, the data is transmitted to the user terminal through the wireless transceiver module. After receiving the data information through its own wireless transceiver module, the user terminal processes it through a data analysis program to determine the connection status between the locking body 1 and the tower foot nail 4, and controls the alarm to issue a corresponding warning. The warning system 2 detects the connection status between the locking body 1 and the tower foot nail 4 and issues a warning reminder based on the connection status, further improving safety and avoiding the shortcomings of traditional methods.

[0042] This invention also provides a method for using a foot-peg type anti-slip and anti-fall locking device for tower climbing. The two locking devices are connected to the safety harness connecting rope 3 worn by the worker. When working at a fixed position on the tower, the locking sleeve 7 is slid downwards to move the locking slider 6 to the lowest position of the locking track 5. After the locking track 5 passes through the tower foot spike 4, the locking sleeve 7 is slid upwards to move the locking slider 6 upwards, so that the locking slider 6 and the locking body 1 tightly hold the tower foot spike 4. The locking sleeve 7 is rotated so that the second guide post 11 engages with the left horizontal channel 92 or the right horizontal channel 93 to achieve mechanical self-locking, ensuring that the locking slider 6 will not slip during construction, thus achieving a stable connection between the locking device and the tower foot spike 4. The warning system 2 detects the connection status between the locking body 1 and the tower foot spike 4. When both locking devices are in an unlocked state, the warning system 2 issues an alarm.

[0043] When workers are climbing the tower, they use two locking devices alternately to keep one locking device connected to the tower footing 4 at all times. The unlocking process between the locking device and the tower footing 4 is as follows: rotate the locking sleeve 7 so that the vertical channel 91 in the second groove 9 is aligned with the second guide post 11, and then slide the locking sleeve 7 downward. The locking slider 6 is driven to slide downward by the cooperation of the first guide post 10 and the first groove 8, thereby releasing the secure connection between the locking device and the tower footing 4.

[0044] In summary, the foot-pronged anti-slip and anti-fall locking device and its usage method of this invention provide safety support and protection for workers performing tower climbing tasks to prevent them from falling from heights. These devices typically include components such as safety belts, locking buckles, and self-locking mechanisms, which, by connecting to the tower climbing structure, ensure that workers have the necessary safety guarantees when performing high-altitude operations.
