Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments. Example
[0016] like Figure 1-4As shown, the adjustable seat mining aerial passenger transport device provided by this utility model includes: a cable gripper 1, which adopts the existing cable gripper structure design and is used to fix it to the steel wire rope of the mining aerial passenger transport device; a square tube 2 is fixedly installed at the bottom of the cable gripper 1, and an adjustable-height seating mechanism is installed on the square tube 2; the seating mechanism includes an adjustment component 3 and a seating component 4, the seating component 4 is used for personnel to sit on, and the seating component 4 includes a seat and a footrest connected to the seat; the adjustment component 3 is used to adjust the distance between the seating component 4 and the top of the square tube 4, that is, to adjust the height of the seating component 4 off the ground; the adjustment component 3 includes a cross bar 30 slidably installed on the square tube 2. The crossbar 30 includes a horizontal bar and a vertical bar. The vertical bar portion of the crossbar 30 is slidably installed inside the square tube 2. Elongated holes are formed on both sides of the square tube 2, through which the horizontal bar portion of the crossbar 30 passes. The length of the elongated holes is sufficient. A sliding connecting tube 31 is fitted onto the crossbar 30. The riding assembly 4 is fixedly connected to the connecting tube 31. Pressure blocks 32 are rotatably installed on both sides of the crossbar 30. The pressure blocks 32 have pointed tips facing the side of the square tube 2. A linkage rod 33 is installed between the connecting tube 31 and the pressure blocks 32. The two ends of the linkage rod 33 are hinged to the connecting tube 31 and the pressure blocks 32, respectively. A rack 21 is fixedly installed on the side of the square tube 2, and the tip of the pressure block 32 is embedded in the tooth groove of the rack 21. A spring 36 is installed between the crossbar 10 and the pressure blocks 32. An upper handle 34 is installed on the crossbar 30, and a lower handle 35 is installed on the connecting tube 31. In use, hold the upper handle 34 and the lower handle 35 with both hands and pull them together, causing the connecting tube 31 to slide up the cross rod 30. This causes the linkage rod 33 to rotate the pressure block 32, moving the end of the pressure block 32 away from the rack 21 and disengaging it. Simultaneously, the spring 36 is stretched, releasing the locking state of the cross rod 30. After adjusting the height of the seating component 4 by sliding the cross rod 30 up and down, release the lower handle 35. Under the action of gravity and the spring 36, the pressure block 32 reverses, and the height of the cross rod 30 is slightly adjusted up and down until the end of the pressure block 32 is embedded in the tooth groove of the rack 21, thus locking the height of the cross rod 30. This allows for convenient use by people of different heights. The overall structure of the device is relatively simple, and the height adjustment is convenient. When riding, the person sits on the seating component 4, holds the lower handle 35 with both hands, and moves forward with the steel cable. Furthermore, after passengers sit on the vehicle, the linkage rod 33 will be pulled downwards under the action of gravity, which will further press the pressure block 32 against the rack 21, making the connection between the cross rod 30 and the square tube 2 more stable, thus improving the stability of the ride.
[0017] By setting up a gripper 1, a square tube 2, and a seating mechanism including an adjustment component 3 and a seating component 4, the height of the seating component 4 can be easily adjusted through the coordinated operation of the upper handle 34 and the lower handle 35, making it convenient for people of different heights to sit and use. The overall structure of the device is simple and easy to operate. Example
[0018] like Figure 4 As shown, a fastening knob 37 is threaded onto the side of the connecting tube 31. One end of the fastening knob 37 presses firmly against the cross bar 30 inside the connecting tube 31, thereby stabilizing the connection between the connecting tube 31 and the cross bar 30. Simultaneously, it stabilizes the connection between the pressure block 32 and the rack 21. This, in turn, stabilizes the height of the riding assembly 4.
[0019] By installing a fastening knob 37 on the side of the connecting tube 31, the stability of the riding assembly 4 can be improved. Example
[0020] like Figure 3-4 As shown, a limiting plate 38 is installed on the cross bar 30. The limiting plate 38 is located outside the pressure block 32 and is used to limit the rotation angle of the pressure block 32. When the pressure block 32 rotates to contact the limiting plate 38, it can no longer rotate, thus limiting the deflection angle of the pressure block 32. At this time, the pressure block 32 just disengages from the rack 21, and the closest distance between the two is 5-10mm. This avoids excessive rotation angle, which would cause the spring 36 to be overstretched, and helps to improve the service life of the spring 36.
[0021] By installing a limiting plate 38 on the cross bar 30, the rotation angle of the pressure block 32 can be easily limited, preventing the spring 36 from being overstretched due to excessive rotation angle.
[0022] Working principle: In use, hold the upper handle 34 and the lower handle 35 with both hands and pull them together. This causes the connecting tube 31 to slide up the cross rod 30, which in turn causes the linkage rod 33 to rotate the pressure block 32. This causes the end of the pressure block 32 to move away from the rack 21 and disengage from it. At the same time, the spring 36 is stretched, releasing the locking state of the cross rod 30. After adjusting the height of the seating component 4 by sliding the cross rod 30 up and down, release the lower handle 35. Under the action of gravity and the tension of the spring 36, the pressure block 32 reverses. Make slight adjustments to the height of the cross rod 30 so that the end of the pressure block 32 is embedded in the tooth groove of the rack 21, thus locking the height of the cross rod 30 and the height of the seating component 4. This allows for convenient use by people of different heights. The overall structure of the device is relatively simple, and the height adjustment is convenient.
