Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1:

[0025] Please see Figures 1-5 A walking device includes two opposing side plates 10. Track wheels 30 are mounted on opposite sides of each side plate 10 via support shafts 20. The side plates 10 are connected and fixed by at least one connecting rod 40. Each side plate 10 also has a protrusion 11 on its opposite side, located on one side of the track wheel 30. At least two mounting grooves 12 are provided on the protrusion 11 near the track wheel 30. A wheel axle 80 is fixedly mounted in each mounting groove 12, and a limiting wheel 70 is mounted on the wheel axle 80. A gap is provided between the track wheel 30 and the limiting wheel 70 for mounting and clamping a track 100. By installing the limiting wheel 70 on the underside of the side plate 10, the track wheel 30 and the limiting wheel 70 clamp the track 100, preventing the walking device from tilting during oblique pulling, thereby eliminating the safety risk of the walking device derailing from the track.

[0026] In this embodiment, see Figure 4 , 5 The support shaft 20 extends outward from between the two side plates 10. The end of the support shaft 20 located on the outer side of the side plate 10 has an external thread. A first nut 21 is screwed onto the support shaft 20 to fix the support shaft 20 onto the side plate 10. The end of the support shaft 20 located on the inner side of the side plate 10 is fitted with the track wheel 30 via a bearing 32. The bearing 32 is limited by a retaining ring 22 mounted on the support shaft 20.

[0027] See Figure 4 The connecting rod 40 is thicker in the middle and thinner at both ends. Both ends of the connecting rod 40 are also provided with external threads. Two side plates 10 are inserted into both sides of the connecting rod 40 through mounting holes. The middle section of the connecting rod 40 limits the position of the side plates 10. After the two side plates 10 are inserted into the connecting rod 40, a second nut 41 is screwed onto the connecting rod 40, thereby limiting and fixing the side plates 10.

[0028] In the embodiment, two track wheels 30 are installed on each side plate 10.

[0029] Further, in order to improve the stability of the installation of the limiting wheel 70, a pressing plate 60 is installed on each side of the protruding part 11, and the axle 80 penetrates the pressing plate 60 and the side plate 10. In this way, the two ends of the axle 80 are supported and fixed by the pressing plate 60 and the side plate 10 respectively, the axle 80 is not easy to bend, and at the same time the limiting wheel 70 is not easy to fall off, thereby improving the stability of the limiting wheel 70. In use, the pressing plate 60 is connected and fixed with the protruding part 11 by screws, and the axle 80 is in interference fit with the holes in the pressing plate 60 and the side plate 10.

[0030] When the pressing plate 60 is installed, referring to Figure 4 , the pressing plate 60 is provided with a relief hole for the middle part of the connecting rod 40 to penetrate.

[0031] In the embodiment, the limiting wheel 70 adopts a bearing.

[0032] Further, referring to Figure 2 , 3 , the two side plates 10 are installed and fixed by the two connecting rods 40, and the hoisting rod 50 is installed on the two side plates 10 between the two connecting rods 40. Referring to Figure 5 , the hoisting rod 50 adopts a screw rod. In installation, the hoisting rod 50 penetrates the through hole on the two side plates 10, and then the third nut 51 is screwed on the hoisting rod 50.

[0033] In use, the lifting eye 111 on the hoisting device 110 is hung by the hoisting rod 50. By setting the hoisting rod 50, it is convenient to install or replace different hoisting devices 110.

[0034] Further, referring to Figure 1 , 3 , the walking device further comprises a reduction motor 90, the reduction motor 90 is installed on one of the side plates 10, the output shaft of the reduction motor 90 extends into between the two side plates 10, the output shaft of the reduction motor 90 is provided with a gear 91, the gear 91 is in meshing transmission with the gear ring structure 31 provided on the side of one of the track wheels 30. By driving one of the track wheels 30 to rotate by the reduction motor 90, the walking device can walk on the track 100.

[0035] Embodiment 2:

[0036] Please refer to Figure 6A kind of hoisting device, using the walking device described in the application, the walking device is suspendedly installed with hoisting equipment 110.In use, the lifting ring 111 on hoisting equipment 110 can be suspended on connecting rod 40 or hoisting rod 50.Hoisting equipment 110 can use electric hoist or electric hoist.

[0037] The working principle or action process of the utility model is as follows:

[0038] Referring to Figure 5 The track 100 is located between the track wheels 30 on both sides, and the track wheels 30 and the limit wheels 70 clamp the track 100. Since the track wheels 30 are single-sided track wheels, a small gap is left between the track wheels 30 and the track 100, and the walking device will not deviate to the left and right by a large distance. Again, the track 100 is abutted on the track wheels 30 by the limit wheels 70, so the walking device will not tilt when it is walking on an inclined cable, eliminating the safety risk of the walking device coming off the track. If the limit wheels 70 break, the protruding part 11 can also play a certain limiting role.
