Technical Field

[0001] The invention relates to the technical field of tower climbing safety devices, and in particular to a nail-type tower climbing anti-side slipping and anti-falling locking buckle device and a use method thereof. Background Art

[0002] At present, the anti-fall protection methods used in on-site tower climbing operations include five-point safety belts with double hooks, safety rings installed on foot nails, anti-fall slide rails, backup safety ropes for drone hanging, etc. The above equipment has defects in flexibility, safety, and maintenance economy. For example, the most commonly used anti-fall equipment is the safety belt anti-fall safety ring. The specific structure of the safety belt anti-fall safety ring can be found at: https: / / tv.cctv.com / 2019 / 10 / 07 / VIDEc6kxb9VL4wXHTd7c5F to191007.shtml ;

[0003] The safety ring of the safety belt is simple in structure. When climbing the tower, hold the safety ring with one hand, and put the rope ring around the tower foot nails. When falling, tighten the rope ring through gravity to lock the tower foot nails. However, this method has certain safety hazards. It is possible that when the worker falls, the safety ring will slide off the foot nails due to the force, and it will not play a protective role. Summary of the invention

[0004] In view of the above-mentioned problems in the prior art, the present invention provides a foot-spike type tower climbing anti-slip and anti-fall locking device and a method of using the same, which solves the problem that the safety belt anti-fall safety ring in the prior art may slip sideways from the foot-spike due to the force when a worker falls, and cannot play a protective role.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is as follows:

[0006] Provided is a foot-spike type tower climbing anti-side slip and anti-fall locking device, which comprises a locking body, a warning system is arranged on the top of the locking body, a locking slide is arranged in the middle, and the bottom is used for fixing and connecting a safety belt connecting rope.

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

[0008] A locking slider is vertically slidably arranged in the locking slideway, and a locking sleeve is vertically slidably connected to the outside of the lock body. The circumferential outer wall of the locking sleeve is penetrated by at least a first groove and a second groove. The first groove is located at the top of the second groove, and the first groove is in an "I"-shaped structure. A first guide column fixedly connected to the outer wall of the locking slider is slidably arranged in the first groove.

[0009] The second groove includes a vertical channel, and the two sides of the vertical channel are respectively connected to a left horizontal channel and a right horizontal channel; a second guide column located in the second groove is arranged on the outer wall of the lock body, and the second guide column is slidably matched with the second groove.

[0010] Furthermore, the middle and bottom of the lock body are hollow cylindrical structures, an auxiliary locking spring is arranged inside the lock body, the bottom end of the auxiliary locking spring is fixed to the bottom of the lock body by a hexagon socket set screw, and the top end of the auxiliary locking spring is in tight contact with the lower end surface of the locking slider. In the above technical solution, the auxiliary locking spring always applies a vertical upward thrust to the locking slider, which can help the locking slider slide up and down more easily, and is more conducive to workers operating the locking device with one hand during construction.

[0011] Furthermore, a latch and a notch in a "1"-shaped structure are provided at the bottom of the lock body. The latch is arranged horizontally and passes through the bottom of the lock body and the notch. A split pin is arranged at the end of the latch. The safety belt connecting rope passes through the notch and is fixed on the latch. The latch is used to fix the safety belt connecting rope, and the split pin is provided to prevent the latch from falling off the lock body.

[0012] Furthermore, the top of the locking slideway and the top of the locking slider are both semicircular curved structures. The beneficial effects of the above technical solution are: making the top of the locking slideway and the top of the locking slider fit more closely with the tower foot nail, increasing the contact area between the locking slideway and the locking slider and the tower foot nail, and enhancing the stability of the connection.

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

A single-chip microcomputer and a wireless transceiver module electrically connected to the single-chip microcomputer are integrated on the circuit board; a push rod is provided at the bottom of the contact switch, and the top of the push rod is connected to the contact switch through a switch spring, and the bottom of the push rod passes through the circuit box and is located in the locking slide.

[0015] The principle of the warning system is: when the locking slider and the lock body are clamped on the tower foot nail, the tower foot nail contacts the bottom of the top rod, causing the top rod to move upward, triggering the contact switch, and the single-chip microcomputer is used to collect and process the state information of the contact switch, and the wireless transceiver module is used to transmit the data information processed by the single-chip microcomputer to the user end. Specifically, the single-chip microcomputer may include an ADC module, a CPU module and a serial port module that are electrically connected in sequence. The single-chip microcomputer converts the analog signal of the switch into a digital signal through the ADC module, and then transmits it to the user end through the wireless transceiver module using the serial port module point-to-point configuration after performing data calculation processing through the CPU module. After the user end receives the data information through its own wireless transceiver module, it processes it through the data analysis program, obtains the connection state of the lock body and the tower foot nail, and controls the alarm to work and issue a corresponding warning. The single-chip microcomputer can use a Teensy 4.1 microcontroller. The wireless transceiver module can use an XBEE module. The power module supplies power to all electrical accessories of the warning system.

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

[0017] Furthermore, the number of the first groove and the number of the second groove are both two; the two first grooves and the second grooves are both symmetrically arranged around the axis of the lock body.

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

[0020] When workers climb the tower, they use two locking devices alternately to climb the tower, and keep one locking device connected to the tower foot nail at all times; the unlocking process between the locking device and the tower foot nail is: rotate the locking sleeve to align the vertical channel in the second groove with the second guide column, and then slide the locking sleeve downward, and drive the locking slider to slide downward through the cooperation of the first guide column and the first groove, thereby releasing the firm connection between the locking device and the tower foot nail.
