Device for standard safety operation of sliding rope

Technical Field

The invention belongs to the field of special detection, and particularly relates to a device capable of detecting operation specification and warning of a high-altitude sliding rope.

Background

The sliding rope is mainly applied to scenic spots and amusement parks. The sliding rope mainly comprises a reinforced concrete foundation, upper and lower station door-type structural supports, a lifting appliance (comprising a pulley and a hanging belt, wherein the pulley is divided into two wheels and four wheels, and forms of speed limit and non-speed limit), a buffer device, a protection device, a lifting appliance recovery device, a bearing rope, a traction rope and the like. The domestic longest sliding rope has length of 660 m and drop height of no more than 60 m.

The current sliding rope operates in the following modes: the tourist is in the last place and is assisted wearing the protective clothing by the staff, and staff communicates with the staff that steps down through the intercom, tells the staff that steps down to have the tourist to slide, and the staff that steps down responds through the intercom and steps down that staff has ready, and the staff that steps down hangs the slide rope hook to the protective clothing of tourist then releases, and the staff that steps down waits and is ready for meeting after the tourist slides down, and the safe arrival of tourist steps down after buffering. The communication between the upper station and the lower station is through the interphone, and the situation of unsmooth communication is unavoidable. If the workers on the upper station are improper and irregular in operation and are not communicated with workers on the lower station, the workers on the upper station are easy to hurt tourists.

the operator above the lanyard presses the "wake up" button of the first control box, which plays "wait for the device below to answer". And when the second control box below the sliding rope receives the wake-up signal sent by the first control box, broadcasting that a tourist slides down and is ready.

The operator below the slide cable presses the 'response' button of the second control box, and the second control box below the slide cable plays the 'answered' to wait for the response above. The first control box above the sliding rope receives the response signal sent by the second control box below, and broadcasts that 'the lower staff is ready', and at the moment, the upper staff starts to wear safety equipment for tourists.

When the safety equipment is worn, and a worker above the safety equipment is disconnected from the hook, the first control box sends a sliding signal to the second control box, meanwhile, the first control box reports that the tourist slides downwards, the second control box reports that the tourist above the safety equipment slides downwards, and the safety equipment is ready for preparation. If the first control box does not receive the response signal of the second step, when the staff above breaks away from the hook, the first control box continuously broadcasts that the staff below is not ready and does not slide downwards, thereby playing a role in warning, and only the hook is closed again, and the broadcasting is stopped.

Furthermore, the sliding end of the hook is provided with a small powerful magnet, the fixed end of the hook is provided with a Hall magnetic device, and the two components form a sensor for detecting the state of the hook, and the state is folding or opening.

Further, the wireless communication mode adopts LoRa communication;

further, if the upper worker has pressed the "wake up" button of the first control box, but the guest temporarily cancels the play, the upper worker presses the "cancel" button of the first control box, and the operation cycle is canceled. Simultaneously, the first control box and the second control box broadcast 'tourist temporarily cancel sliding'.

Further, if the upper worker presses the "wake-up" button of the first control box, the lower worker also presses the "response" button of the second control box, but the lower worker temporarily leaves an emergency, the lower worker presses the "cancel" button of the second control box, and the upper device continuously broadcasts that the lower worker is not in place and does not slide down until the upper worker presses the "cancel" button of the first control box.

The invention has the beneficial effects that: the sliding rope hook is provided with a sensor for detecting the closing and opening of the hook, and a sensor signal is connected with a control box through a cable. When the sliding end slides up and down, the Hall sensor can detect that the hook is opened and closed. The detected signals are sent to a control box, and correct operation instructions are sent out according to the operation logic of four keys on the uplink control box and the downlink control box, so that the standard and the safety of the sliding cable operation are ensured. The wireless communication mode selects LoRa communication to ensure smooth communication, and simultaneously prompts through voice.

fig. 2 is an overall schematic diagram of the control box.

Detailed Description

The technical scheme of the invention is cleared and fully described below with reference to the accompanying drawings.

As shown in fig. 1, the upper part 1 of the sliding rope hook is the friction part of the hook and the sliding rope; the lower part 4 of the sliding rope hook is used for bolting safety equipment on tourists, the powerful magnet 3 is arranged at the sliding end 2 of the hook and can slide up and down, and the Hall element 5 is arranged at the place where the fixed end of the hook is close to the magnet. When the slide end 2 slides up and down, the hall element detects the position of the magnet, which represents the opening and closing of the hook. The Hall element is connected into the control box through a thin cable, signals pass through the conditioning circuit to obtain switching value, and the switching value is used for detecting the state of the hook for the MCU.

As shown in fig. 2, the slide cable has a control box on the top and bottom, the control box has two keys and a speaker, respectively, and the two control boxes communicate through LoRa communication. The keys on device 1 are used to wake up the lower device (key a) and cancel operation (key B), and the keys on device 2 are used to answer the upper device (key C) and cancel operation (D). The four keys are keys controlled by electromagnet, and if the operation sequence and logic described below are not met, the corresponding keys cannot be pressed. The speaker is used for voice prompt operation.

The logic of the four keys in normal operation is as follows:

in the first step, an operator above the slide cable presses a wake-up button A, and the device above the slide cable plays a wait for response of the device below. When the device below the sliding rope receives the wake-up signal sent by the device above, the voice broadcast is performed, and a tourist slides down above the voice broadcast to be ready.

And secondly, pressing a response button C by a worker below the sliding rope, and playing a response by equipment below the sliding rope to wait for the response above. And the upper device of the sliding rope receives a response signal sent by the lower device, so that the lower staff is ready for voice broadcasting, and the upper staff starts to wear the safety device for the tourist.

And thirdly, after the safety equipment is worn, when the staff above the safety equipment breaks away from the hook, the upper equipment sends a 'sliding down' signal to the lower equipment, and meanwhile, the upper equipment broadcasts 'the tourist slides down' through voice. Simultaneously, the lower device broadcasts a voice message that the upper tourist has slipped down and is ready. If the upper equipment does not receive the response signal of the second step, the upper equipment continuously broadcasts that the lower staff is not ready and does not slide down at the moment when the upper staff is disconnected from the hooks, so that a warning effect is achieved, and voice broadcasting is stopped only by closing the hooks again.

The logic of the four keys during abnormal operation is as follows:

(1) If the upper worker has pressed button a, but the guest temporarily cancels the play, the upper worker presses the "cancel" button B, and the operation cycle is canceled. Meanwhile, the upper equipment and the lower equipment simultaneously broadcast 'tourists temporarily cancel sliding', and the hooks cannot be disengaged.

(2) If the upper staff presses the button A, the lower staff also presses the button C to respond, but the lower staff temporarily leaves in emergency, then the lower staff presses the cancel button D, the upper equipment continuously broadcasts the voice that the lower staff is not in place and does not slide down until the upper staff presses the button B, and the hook cannot be released.

In conclusion, the invention can effectively avoid injury to tourists, improve communication efficiency between boarding and disembarking and standardize operation of staff. The magnetic device and the magnet arranged on the hook can effectively detect whether the hook is opened or closed. The upper station and the lower station are both provided with a control box and a voice broadcasting device. The upper station and the lower station realize wireless communication through stable LoRa communication, and realize linkage control of four keys. The sliding rope operation safety device is simple in structure, stable, reliable and easy to install, can stably detect the operation state and send out voice prompts, and ensures the safety and the specification of the sliding rope operation.

The foregoing is a preferred embodiment of the invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the following claims.
