[0029] By utilizing the cooperation between the ground rail vehicle 1 and the ground vehicle guide rail 12 and the cooperation between the sky rail vehicle 5 and the sky vehicle guide rail, the position adjustment of the cargo-carrying mechanism 3, the lifting drive mechanism 4, and the two load-bearing columns 2 can be realized, enabling the stacker to pick up and place the shelves 13 at different positions on the storage rack; by using the two load-bearing columns 2 to share the load borne by the cargo-carrying mechanism 3, the load-carrying capacity of the cargo-carrying mechanism 3 is improved, and the application scenario of the stacker can be expanded; by using the safety protection mechanism 9 to provide anti-falling protection for the cargo-carrying mechanism 3, the falling of the cargo-carrying mechanism 3 is prevented, and the safety of the stacker is improved.

[0030] Further, the sky rail vehicle 5 includes a top moving seat 501 and two top guiding units; the top guiding unit includes two top rollers 503; the top rollers 503 of the two top guiding units are respectively rotatably installed at the left and right ends of the upper side of the top moving seat 501; the two top rollers 503 of the top guiding unit clamp the sky vehicle guide rail; top mounting seats 502 are arranged at the left and right ends of the lower side of the top moving seat 501; the upper ends of the two load-bearing columns 2 are respectively fixed on the two top mounting seats 502.

[0031] The overhead crane guide rail is clamped by the top rollers 503 of two top guiding units, and the overhead crane guide rail is parallel to the ground vehicle guide rail 12, ensuring that the top moving seat 501 and the load-bearing column 2 can move along with the ground rail vehicle 1.

[0032] Furthermore, the ground rail vehicle 1 includes a bottom moving seat 101, a bottom moving motor 104, two bottom traveling wheels 105 and two bottom guiding units; both of the two bottom guiding units include two bottom rollers 107; the two bottom traveling wheels 105 are respectively rotatably installed at both ends of the lower side surface of the bottom moving seat 101, and both travel on the ground vehicle guide rail 12; the bottom moving motor 104 is used to drive one of the bottom traveling wheels 105 to rotate; the bottom rollers 107 of the two bottom guiding units are respectively rotatably installed at the left and right ends of the upper side surface of the bottom moving seat 101; the two bottom rollers 107 of the same bottom guiding unit clamp the ground vehicle guide rail 12; bottom mounting seats 102 are arranged at the left and right ends of the upper side surface of the bottom moving seat 101; the lower ends of the two load-bearing columns 2 are respectively fixed on the two bottom mounting seats 102; two buffer shock absorbers 10 are installed on both the upper side surface of the bottom moving seat 101 and the lower side surface of the top moving seat 501; a trolley wire is installed in parallel on one side of the ground vehicle guide rail 12; a current collector 103 matched with the trolley wire is installed on the bottom moving seat 101 through a power supply support 108.

[0033] The bottom moving motor 104 is used to drive one of the bottom traveling wheels 105 to travel along the ground vehicle guide rail 12. At the same time, the bottom rollers 107 of the two bottom guiding units clamp the ground vehicle guide rail 12 to guide the bottom moving seat 101, realizing the movement adjustment of the ground rail vehicle 1 for the overhead rail vehicle 5 and the two load-bearing columns 2; the buffer shock absorbers 10 are used to shock-absorb and buffer the cargo-carrying mechanism 3.

[0034] Furthermore, the cargo-carrying mechanism 3 includes a cargo-carrying platform 301 and a telescopic forklift 311.

[0035] Lifting guide rails 312 are vertically installed on the opposite side surfaces of the two load-bearing columns 2; adjusting brackets 302 are fixed on the left and right edges of the cargo-carrying platform 301; two lifting traveling wheels 307 are installed on each adjusting bracket 302; the lifting traveling wheels 307 on the two adjusting brackets 302 respectively travel on the two lifting guide rails 312; lifting guiding units are installed on both the upper and lower sides of the two adjusting brackets 302; the lifting guiding unit includes two lifting rollers 306; the two lifting rollers 306 clamp the corresponding side lifting guide rail 312; enclosures 303 are installed on both the front and back sides of the adjusting bracket 302; the telescopic forklift 311 is longitudinally telescopically installed on the cargo-carrying platform 301 and is used for picking up and placing the goods shelves 13 on the storage rack.

[0036] The output end of the telescopic fork 311 extends to the lower side of the picking and placing shelf 13. The lifting drive mechanism 4 drives the cargo-carrying mechanism 3 to move slightly upward, so that the output end of the telescopic fork 311 lifts the picking and placing shelf 13. Then the output end of the telescopic fork 311 retracts, realizing the removal of the shelf 13. The lifting drive mechanism 4 drives the cargo-carrying mechanism 3 to move to the place where the storage shelf places the shelf 13. The output end of the telescopic fork 311 extends. The lifting drive mechanism 4 drives the cargo-carrying mechanism 3 to move slightly downward. The lower edge of the shelf 13 is supported on the storage shelf and separated from the telescopic fork 311, realizing the storage of the shelf 13. Two lifting rollers 306 are used to clamp the lifting guide rail 312 to limit the vertical movement of the cargo platform 301 and prevent the cargo platform 301 from shaking during lifting. The lifting walking wheels 307 are used to reduce the friction between the adjusting bracket 302 and the lifting guide rail 312.

[0037] Further, the safety protection mechanism 9 includes a tension pulley 902, a speed-limiting steel wire rope 903 and a linkage speed limiter 904;

[0038] A safety clamp 901 is installed on the left adjusting bracket 302. The safety clamp 901 is used to hold the left lifting guide rail 312 tightly. A linkage guide rail 907 is vertically installed on the left adjusting bracket 302. A sliding seat 908 is vertically slidably installed on the linkage guide rail 907. A linkage wheel 905 is installed and fixed on the sliding seat 908. A driving rod 906 is fixed on the sliding seat 908. The end of the driving rod 906 is installed on the upper end of the lifting rod of the safety clamp 901.

[0039] The linkage speed limiter 904 and the tension pulley 902 are respectively installed on the upper and lower sides of the left load-bearing column 2;

[0040] The speed-limiting steel wire rope 903 is tensioned and installed on the tension pulley 902, the linkage speed limiter 904 and the linkage wheel 905.

[0041] By utilizing the cooperation among the safety clamp 901, the linkage wheel 905, the tensioning wheel 902, the speed-limiting steel wire rope 903 and the linkage speed limiter 904, the over-speed safety protection for the cargo platform 301 during its downward fall is achieved. The rated speed range of the linkage speed limiter 904 is preset. When the downward movement speed of the cargo platform 301 is within the rated speed range, the speed-limiting steel wire rope 903 moves along with the linkage wheel 905. At this time, there is no displacement between the speed-limiting steel wire rope 903 and the linkage wheel 905. When the downward movement speed of the cargo platform 301 exceeds the rated speed range, the linkage speed limiter 904 monitors that the moving speed of the speed-limiting steel wire rope 903 following the linkage wheel 905 is too fast. At this time, the linkage speed limiter 904 brakes the speed-limiting steel wire rope 903, and friction is generated between the speed-limiting steel wire rope 903 and the linkage wheel 905. The linkage wheel 905 pulls up the pull rod of the safety clamp 901 through the drive rod 906. The wedge block of the safety clamp 901 is driven by the pull rod to tightly press on the lifting guide rail 312 to lock the lifting guide rail 312. The suddenly increased friction stops the downward movement of the cargo platform 301, realizing the emergency stop of the cargo platform 301.

[0042] Further, the lifting drive mechanism 4 includes a traction machine 401, a pulley block and two traction steel wire ropes 402; the pulley block includes a first pulley 405, a second pulley 406, a third pulley 407, a fourth pulley 408, a fifth pulley 409 and a sixth pulley 410; steel wire rope shock absorbers 403 are arranged on the upper sides of the two load-bearing columns 2.

[0043] The traction machine 401 is installed on the lower side of the left load-bearing column 2; the first pulley 405 and the fourth pulley 408 are respectively rotatably installed at the left ends of the front and rear side surfaces of the top moving seat 501; the third pulley 407 and the second pulley 406 are respectively rotatably installed at the left sides of the front and rear side surfaces of the top moving seat 501; the fifth pulley 409 and the sixth pulley 410 are respectively rotatably installed at the right sides of the front and rear side surfaces of the top moving seat 501.

[0044] Lifting pulleys 411 are respectively rotatably installed on the two adjusting brackets 302.

[0045] One ends of the two traction steel wire ropes 402 are respectively installed on the two traction wheels of the traction machine 401; the other ends of the front and rear traction steel wire ropes 402 are respectively installed on the steel wire rope shock absorbers 403 on the left and right sides; the front traction steel wire rope 402 is successively installed on the fourth pulley 408, the fifth pulley 409, the right lifting pulley 411 and the sixth pulley 410; the rear traction steel wire rope 402 is successively installed on the first pulley 405, the second pulley 406, the left lifting pulley 411 and the third pulley 407.

[0046] With the support of the pulley block for the two traction steel ropes 402, the cooperation between the traction steel rope 402 and the lifting pulley 411 can be achieved. Compared with the way that the traction steel rope 402 is directly connected to the cargo mechanism 3, the cooperation between the traction steel rope 402 and the lifting pulley 411 makes the lifting of the cargo mechanism 3 more stable.

[0047] Furthermore, a control cabinet 8 is installed on the right load-bearing column 2; pedals 11 are horizontally fixed on both the upper and lower side surfaces of the control cabinet 8; a lower ladder 7 is fixedly connected between the two pedals 11; an upper ladder 6 is vertically installed on the load-bearing column 2 above the upper pedal 11; and a fence is installed on the upper pedal 11.

[0048] The lower ladder 7 and the upper ladder 6 facilitate the maintenance personnel to climb and maintain the upper side of the stacker, and the fence improves safety.
