detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, this embodiment provides a support luffing device for an indoor rock climbing machine, including an external support frame 23 and a rock climbing machine body frame 22, and the two sides of the rock climbing machine body frame 22 are connected by the first bearing 2 and External support frames 23 are connected. A drive device and a luffing mechanism are arranged on the external support frame 23, and the drive device is installed on the external support frame 23 for driving the luffing mechanism, and the luffing mechanism is connected with the rock climbing machine body frame to realize the The body frame swings within a certain angle range.

As shown in Figures 2, 3, and 4, the external support frame 23 includes external support brackets 1 on both sides, external fixing frames 3, and external frame connecting rods 7, and the supports 1 on both sides are connected by external frame connecting rods 7. The fixed frame 3 is connected to the bracket 1 through a strip connecting plate 8 . Wherein, the support 1 on both sides and the external frame connecting rod 7 are fixed together by the triangular connecting piece 11, wherein, the bar-shaped connecting plate 8 and the triangular connecting plate 11 are respectively fixed by bolts through the threaded hole 20 and the threaded hole 21 (as shown in Fig. 6 and 7). The first bearing 2 is installed in the middle part of the strip connecting plate 8, and the first bearing 2 is a cast steel vertical bearing.

In this embodiment, the worm gear mechanism is selected as the driving device, that is, the worm gear mechanism 9 is arranged symmetrically on both sides of the external support frame 23 . The luffing mechanism includes the luffing rotary rod 4, the first luffing connecting rod 5, and the second luffing connecting rod 6. The worm gear mechanism 9 is installed on the external support frame 23, and the worm gears of the two worm gear mechanisms 9 Set on both ends of the luffing rotary rod 4, the luffing rotary rod 4 is horizontally installed on the external support frame 23, the upper end of the first luffing rotary rod 5 is fixedly connected with the luffing rotary rod 4, and the lower end It is hinged with the front end of the second luffing connecting rod 6 , and the tail end of the second luffing connecting rod 6 is hinged with the lower end of the rock climbing machine body frame to realize the swing of the rock climbing machine body frame within a certain angle range. Wherein, the first luffing connecting rod 5 and the second luffing connecting rod 6 are arranged at a certain angle. As shown in Figure 5, the worm gear mechanism 9 is mainly composed of a motor base 12, a coupling 13, a motor 14, a screw hole 15, a UCP20 seated bearing 16, a worm 17, a retaining ring 18 for a shaft and a worm wheel 19, wherein the motor The seat 12 is used to fix the motor 14 on the worm gear mechanism 5; two UCP20 seated bearings 16 are used to fix the worm 17; the shaft retaining ring 18 is set in the middle of the worm wheel 19, and is used to fix the luffing rod of the transverse structure 4.

In this embodiment, in order to prevent the mutual interference between the mechanisms due to the large inclination angle during the luffing process of the rock climbing machine, a groove is provided on the front end of the second luffing connecting rod 6. When the first luffing connecting rod 6 When the rod 5 and the second luffing link 6 move relative to each other, the groove is used to accommodate the first luffing link 5 . Simultaneously, the afterbody of the second luffing connecting rod 6 is equipped with a second bearing 10, which is used to support the lower shaft of the indoor rock climbing machine body frame, and the second bearing 10 is a vertical bearing.

When the system issues the luffing command, the motor 14 outputs power, and the worm 17 is driven to rotate through the coupling 13.
