Description

Technical Field

[0001] This utility model relates to the technical field of measuring the running speed of ziplines, and in particular to a follow-up speed measuring device for zipline equipment. Background Technology

[0002] In my country, ziplines are classified as large-scale amusement facilities under special regulations, and one of the key design considerations is operating speed. Excessive speed can cause passengers to be injured due to sudden acceleration during braking upon entering the platform, while insufficient speed may leave passengers stranded outside the platform, requiring emergency rescue. Existing speed measurement methods, such as GPS positioning and radar speed measurement, suffer from high cost, low accuracy, and susceptibility to environmental factors, making them unsuitable for the speed measurement requirements of zipline equipment. Therefore, current speed measurement devices for ziplines typically rely on stationary personnel using handheld radar guns for speed detection. However, this method presents the following problems:

[0003] 1. Inability to monitor speed throughout the entire process: Existing handheld radar gun speed measurement methods can only be tested by fixed personnel at both ends of the zipline, and cannot monitor the speed of passengers throughout the entire zipline ride.

[0004] 2. Manual measurement error: Relying on handheld devices for speed measurement introduces errors due to human operation, affecting the accuracy of the measurement results.

[0005] 3. Inability to monitor speed in real time: Existing speed measurement methods do not have a device designed to automatically measure speed as the passenger glides, which limits the continuity and real-time nature of speed measurement.

[0006] Therefore, the present invention aims to design a speed measuring device that can automatically follow passengers as they glide, measure and record speed in real time throughout the entire zipline motion, and reduce human error. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a follow-up speed measuring device for zipline equipment.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A following speed measuring device for zipline equipment includes an assembly frame with an adjustment mechanism and an adjustment wheel. The assembly frame has driven wheels of the same size and shape as the adjustment wheel on both sides near the adjustment wheel, forming an assembly position for the zipline to pass through. Both the driven wheels and the adjustment wheel have an encoder disk on their side near the assembly frame. The assembly frame also has photoelectric sensors that cooperate with the encoder disks near the driven wheels and adjustment wheel. These photoelectric sensors are connected to a data processor to calculate the running speed of the zipline equipment. Specifically, the assembly frame, adjustment wheel, and driven wheels work together to convert the running speed of the zipline equipment into the rotational speeds of the adjustment wheel and driven wheel. The speed of the adjustment wheel or driven wheel is then calculated by the cooperating encoder disk, photoelectric sensor, and data processor, thereby obtaining the running speed of the zipline equipment.

[0010] Preferably, there is a clearance between the adjusting wheel, the driven wheel and the mounting frame, and the clearance is greater than the thickness of the encoder disk plus the length of the photoelectric sensor, so as to avoid wear on the encoder disk and photoelectric sensor when the adjusting wheel and the driven wheel rotate.

[0011] Preferably, the adjustment mechanism includes an adjustment groove on the assembly frame, a slider in the adjustment groove, a first assembly frame on the slider, and an adjustment wheel rotatably mounted on the first assembly frame. The side of the adjustment groove away from the driven wheel is provided with an assembly plate, and an adjustment rod is screwed onto the assembly plate. The end of the adjustment rod near the adjustment wheel is rotatably connected to the first assembly frame. By rotating the adjustment rod, the position of the adjustment wheel can be changed so that the adjustment wheel and the two driven wheels are in close contact with the cable, reducing slippage between the adjustment wheel, the driven wheels and the cable.

[0012] Preferably, a tensioning spring is fitted onto the part of the adjusting rod located between the first assembly frame and the assembly plate to prevent the position of the adjusting rod from moving during operation of the following speed measuring device.

[0013] Preferably, the assembly frame is T-shaped and is formed by connecting horizontal and vertical rods. An adjustment groove is provided on the vertical rod. The driven wheel is rotatably provided on the second assembly frame. The second assembly frame is fixedly connected to the horizontal rod. Both the horizontal and vertical rods are provided with traction rings. The traction rings are detachably connected to the zipline-type equipment via traction ropes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The speed measuring device disclosed in this utility model can follow the passenger's gliding in real time and dynamically monitor the zipline descent speed, overcoming the time lag of the traditional fixed-point speed measuring method, providing more timely and accurate safety data, and reflecting the passenger's actual gliding speed in real time.

[0016] 2. The design of multiple driven wheels and adjusting wheels in this utility model makes the speed measuring device more stable during sliding. The adjustment mechanism also ensures a tight fit between each driven wheel and adjusting wheel and the wire rope, thus improving the accuracy of speed measurement.

[0017] 3. The speed measuring device disclosed in this utility model adopts a reflective photoelectric sensor and encoder disk technology. It obtains speed information by detecting the change of light signal on the reflective surface when each adjusting wheel and driven wheel rotates. The photoelectric sensing technology has the characteristics of strong anti-electromagnetic interference capability and fast response speed, and can work stably in complex environments.

[0018] 4. The speed measuring device disclosed in this utility model has a simple structure and is easy to install. It can be directly fixed on the zipline without the need for large-scale modification of existing zipline equipment, which reduces installation and time costs. At the same time, it is not limited by the length or tilt angle of the zipline during use and can be widely used in various scenarios such as high-altitude ziplines, extreme sports equipment, and freight ziplines.

[0019] 5. The speed measuring device disclosed in this utility model is fixed on the cable by the assembly position formed by the adjusting wheel and the driven wheel. There is no need to set up additional fixed points or brackets, which saves material and labor costs. Compared with the traditional fixed point speed measuring method, it effectively reduces the installation cost and maintenance complexity. In the long-term use, if damage or failure occurs, only the corresponding parts need to be replaced, without the need for overall replacement, which reduces maintenance costs.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example 1

[0026] like Figure 1-3 The illustrated follow-up speed measuring device for zipline equipment includes an assembly frame 1, an adjustment mechanism 2 on the assembly frame 1, and an adjustment wheel 3 mounted on the adjustment mechanism 2. The assembly frame 1 has driven wheels 4 of the same size and shape as the adjustment wheel 3 mounted on both sides near the adjustment wheel 3, forming an assembly position between the two driven wheels 4 and the adjustment wheel 3 for the zipline 5 to pass through. Both the driven wheels 4 and the adjustment wheel 3 have an encoder 6 on their side near the assembly frame 1. The assembly frame 1 also has photoelectric sensors 7 that cooperate with the encoder 6 near the driven wheels 4 and the adjustment wheel 3. The photoelectric sensors 7 are connected to a data processor to calculate the rotational speed of the driven wheels 4 and the adjustment wheel 3, thereby reflecting the operating speed of the zipline equipment.

[0027] In practical implementation, the aforementioned speed measuring device is connected to the zipline equipment, and its mounting position is fitted onto the zipline 5. The position of the adjusting wheel 3 is adjusted by the adjusting mechanism 2 to ensure that the adjusting wheel and the two driven wheels are in close contact with the zipline 5. When the zipline equipment slides on the zipline 5, the traction speed measuring device moves accordingly. During this process, the adjusting wheel 3 and driven wheel 4, which form the mounting position, rotate using the friction between them and the zipline 5. During the rotation of the adjusting wheel 3 and driven wheel 4, the encoder disk 6 on them rotates synchronously, and is detected in real time by the corresponding photoelectric sensor 7. The information detected in real time by the photoelectric sensor 7 is fed back to the data processor, which calculates the rotational speed and linear velocity of each driven wheel 4 and adjusting wheel 3 using the following formula. The linear velocity of either the driven wheel 4 or the adjusting wheel 3 can reflect the sliding speed of the zipline equipment.

[0028]

[0029] v = n·c (2)

[0030] In the formula: n is the rotational speed of the corresponding driven wheel 4 or adjusting wheel 3, in r / s; N is the number of pulses, which is measured by the combination of the encoder disk 6 and the photoelectric sensor 7; k is the number of marks on the encoder disk; t is the time interval, in s; v is the linear velocity; and c is the circumference of the corresponding driven wheel 4 or adjusting wheel 3.

[0031] This invention uses a mounting frame 1, an adjusting wheel 3, and a driven wheel 4 to work together to convert the running speed of the zipline equipment into the rotational speed of the adjusting wheel 3 and the driven wheel 4. Then, the real-time speed of the adjusting wheel 3 or the driven wheel 4 is calculated by the cooperating encoder 6, photoelectric sensor 7, and data processor, thereby obtaining the real-time running speed of the zipline equipment. During use, the speed measuring device disclosed in this invention follows the passenger's gliding in real time, which can dynamically monitor the zipline's descent speed, overcome the time lag of traditional fixed-point speed measuring methods, and provide more timely and accurate safety data, reflecting the passenger's actual gliding speed in real time.

[0032] Preferably, there is a clearance between the adjusting wheel 3, the driven wheel 4 and the mounting frame 1, and the clearance is greater than the thickness of the encoder disk 6 plus the length of the photoelectric sensor, so as to avoid the situation where the adjusting wheel 3 and the driven wheel 4 wear the encoder disk 6 and the photoelectric sensor 7 when they rotate.

[0033] Preferably, the adjustment mechanism 2 includes an adjustment groove 21 formed on the assembly frame 1, a slider 22 is provided in the adjustment groove 21, a first assembly frame 23 is provided on the slider 22, and the adjustment wheel 3 is rotatably mounted on the first assembly frame 23. The side of the adjustment groove 21 away from the driven wheel 4 is provided with an assembly plate 24, and an adjustment rod 25 is screwed onto the assembly plate 24. The end of the adjustment rod 25 near the adjustment wheel 3 is rotatably connected to the first assembly frame 23. After the assembly position is assembled with the sliding cable 5, the position of the adjustment wheel 3 can be changed by rotating the adjustment rod 25 so that the adjustment wheel 3 and the two driven wheels 4 are in close contact with the sliding cable 5. During the operation of the speed measuring device, this reduces the slippage phenomenon between the adjustment wheel 3 and the driven wheels 4 and the sliding cable 5, making the final measured sliding speed more accurate.

[0034] Preferably, a tension spring 26 is fitted onto the part of the adjusting rod 25 located between the first assembly frame 23 and the assembly plate 24. When the tension spring 26 is in a free state, its length is greater than the distance between the first assembly frame 23 and the assembly plate 24, so that the tension spring 26 located on the part of the adjusting rod 25 located between the first assembly frame 23 and the assembly plate 24 is always in a compressed state, thereby preventing the position of the adjusting rod 25 from changing during the operation of the speed measuring device.

[0035] In this embodiment, the assembly frame 1 is T-shaped and is formed by connecting horizontal rod 11 and vertical rod 12. The adjustment groove 21 is opened on the vertical rod 12. The driven wheel 4 is rotatably provided on the second assembly frame 8. The second assembly frame 8 is fixedly connected to the horizontal rod 11. Both the horizontal rod 11 and the vertical rod 12 are provided with traction rings 9. The traction rings 9 are detachably connected to the zipline-like equipment through traction ropes.

[0036] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
