Description

Technical Field

[0001] This utility model relates to the field of zipline safety technology, and in particular to a zipline trolley with speed measurement and braking functions. Background Technology

[0002] Ziplines are non-powered amusement facilities among large-scale amusement rides. A zipline consists of a fixed support cable, a trolley that can slide along the support cable, and passenger equipment suspended under the trolley. Passengers slide from the upper station to the lower station by their own weight. The zipline trolley is the key equipment for carrying passengers in the zipline.

[0003] With the rapid development of amusement facilities, the spans and elevation differences of ziplines are increasing, and the operating speeds of ziplines and trolleys are becoming faster. Some ziplines even cross canyons with extremely complex terrain. In the inspection and testing of amusement facilities, it is difficult to measure whether the maximum operating speed of ziplines and trolleys meets design requirements using conventional testing tools and methods. Furthermore, during operation, the operating speed of ziplines and trolleys is greatly affected by wind load and passenger posture, frequently resulting in zipline and trolley speeds exceeding design speeds and exceeding the standard speed limits when entering stations.

[0004] The current traditional braking method for zipline trolleys involves installing a buffer spring in the approach section. This method cannot control the maximum approach speed of the zipline trolley. When the approach speed is too high, the impact between the zipline trolley and the buffer spring is significant, easily causing injury or death. Operating speed and approach speed are crucial dynamic parameters for zipline trolleys; therefore, their measurement and control are essential for the safe operation of the amusement facility. How to measure the operating speed and approach speed of the zipline trolley, and how to effectively and smoothly brake it when it exceeds design values ​​and regulatory / standard requirements, have become urgent problems to be solved.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this invention is to provide a zipline pulley with speed measurement and braking functions to solve the problems existing in the prior art, and to effectively measure and control the running speed and station entry speed of the zipline pulley.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1 to 2 As shown, this embodiment provides a zipline trolley with speed measurement and braking functions, including a frame 1, a first wheel set 2, a second wheel set 3, an encoder 4, an electromagnetic brake 5, and a controller. The first wheel set 2 includes two first wheels 6, which are mounted on the frame 1 and are used to rotate downwards along the load-bearing cable. The second wheel set 3 includes a brake wheel axle 7 and two second wheels 8. The brake wheel axle 7 is mounted on the frame 1 and is rotatable. The second wheels 8 are fixedly mounted on the brake wheel axle 7 and are used to rotate downwards along the load-bearing cable. The electromagnetic brake 5 is fixedly mounted on the frame 1 and is mounted on the brake wheel axle 7, enabling it to brake the brake wheel axle 7. The encoder 4 is fixedly mounted on the frame 1 and can detect the rotational speed of the brake wheel axle 7. The controller is fixedly mounted on the frame 1 and is communicatively connected to the encoder 4 and the electromagnetic brake 5, enabling it to control the operation of the electromagnetic brake 5.

[0028] The zipline trolley provided in this embodiment, equipped with speed measurement and braking functions, allows the first wheel 6 and the second wheel 8 to slide freely along the carrying cable from the upper station to the lower station under the action of gravity. The encoder 4 collects the rotational speed signals of the brake wheel axle 7 and the second wheel 8, enabling full-process measurement of the zipline trolley's running speed and station entry speed. This solves the problem that conventional testing tools and methods in the inspection and testing of large-scale amusement facility zipline equipment cannot measure and monitor the maximum running speed and station entry speed of the zipline trolley. This provides technical support for the inspection and testing of amusement facilities. Furthermore, the controller controls the operation of the electromagnetic brake 5, which brakes the brake wheel axle 7, facilitating speed control of the zipline trolley. This ensures that the maximum running speed of the zipline trolley does not exceed the design value or can be braked and decelerated in time if it does, and that the station entry speed does not exceed the regulatory and standard requirements or can be braked and decelerated in time if it does, ensuring a smooth entry into the station. This effectively solves the technical problem of large impact when braking at the station in traditional zipline equipment, improving operational safety and intelligent monitoring levels.

[0029] like Figure 3 As shown, in this embodiment, the controller adopts a PLC control module. Specifically, the PLC control module is pre-set with a conventional dual-condition judgment algorithm. During operation, the PLC control module processes the pulse signals collected by the encoder 4, calculates the speed and position timing data of the zipline trolley in real time, and stores it. When the zipline trolley's running speed exceeds the maximum design speed or the zipline trolley's speed exceeds 6 m / s at the position 3m before entering the station, the PLC control module controls the electromagnetic brake 5 to apply progressive braking to the brake wheel axle 7, realizing precise control of the zipline trolley's speed throughout the entire process and enabling the zipline trolley to enter the station smoothly. This solves the technical problems of large braking impact and uncontrollable running speed of traditional zipline equipment, providing a guarantee for the safe operation of amusement facilities.

The controller and the wireless transmission module are communicatively connected so that the speed and position timing data of the zipline trolley can be transmitted in real time to a remote PC monitoring terminal. The PC monitoring terminal can have built-in relevant analysis programs or software to generate speed-time curves and position-time curves in real time, and obtain key parameters such as the maximum operating speed and station entry speed throughout the entire operating cycle, and display them in real time, realizing data storage, wireless transmission, and visual analysis.
