[0028] A limit arm 24 extending forward is provided at the front end of the transverse guide wheel support 23; a longitudinal hollow slot 20 is extended along the longitudinal direction at the upper section of the bottom of the longitudinal guide slot 10 of the longitudinal guide slot column 11; a transverse expander 27 is fixedly installed in the middle of the side of the transverse trolley 8 close to the longitudinal guide slot column 11, and the expansion and contraction direction of the columnar expansion head 28 of the transverse expander 27 is perpendicular to the extension direction of the lifting guide rail beam 14; the outer diameter of the columnar expansion head 28 is not larger than the slot width of the longitudinal hollow slot 20; when the transverse trolley 8 runs along the length direction of the lifting guide rail beam 14, when the middle part of the transverse trolley 8 just reaches the position of the longitudinal hollow slot 20 of the longitudinal guide slot column 11, the columnar expansion head 28 of the transverse expander 27 can be extended to be inserted into the longitudinal hollow slot 20; in order to reduce friction, a slip ring is provided on the outer cover of the columnar expansion head 28.

[0029] An oblique ejector 29 extending rearward and upward is fixedly provided on the rear side of the upper end of the longitudinal guide groove column 11, and a fixed arm 33 is provided obliquely above the ejector rod 30 of the oblique ejector 29, and the fixed arm 33 is fixed to the fixing device; the lower end of the fixed arm 33 is integrally connected with a supporting block 31, and a supporting surface 32 parallel to the end surface of the ejector rod 30 is provided on the side of the supporting block 31 close to the ejector rod 30; when the end of the limiting arm 24 limits contact with the limiting end surface 26 of the transverse guide groove 25, the ejector rod 30 of the oblique ejector 29 can be extended obliquely to press the supporting surface 32 of the supporting block 31; when the ejector rod 30 of the oblique ejector 29 is fully retracted, the upper end of the ejector rod 30 is lower than the lower end of the supporting block 31.

[0030] Working principle: Overall work flow: the transverse moving trolley 8 runs to the front end of the lifting guide rail beam 14, and then rises to the highest position, and the unloading device takes away the goods loaded on the transverse moving trolley 8; then the empty transverse moving trolley 8 needs to run to the rear end of the lifting guide rail beam 14, and then descends to the lowest position, and the loading device loads the goods onto the transverse moving trolley 8; this reciprocating operation allows the transverse moving trolley 8 to continuously transport the goods from a to a farther and higher b.

[0031] Detailed process of the second embodiment:

[0032] Step 1: In the initial state, the end of the limit arm 24 contacts the limit end surface 26 of the transverse guide groove 25, and the push rod 30 of the oblique pusher 29 extends to the top support surface 32 of the top support block 31, so that the position of the longitudinal guide groove column 11 is locked; at this time, the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are both in a vertical state under the constraint of the longitudinal guide groove column 11 in the locked state; in the initial state, the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are both in an upwardly extended state, and the transverse trolley 8 is at the front end of the lifting guide rail beam 14, so that the transverse trolley 8 is just in the unloading position at this time; in this state, the unloading device can take away the goods loaded on the transverse trolley 8;

[0033] Step 2: First, by synchronously contracting the first telescopic cylinder 1 and the second telescopic cylinder 2, the lifting guide beam 14 and the unloaded empty transverse trolley 8 are lowered for the first time h1, and then the transverse trolley 8 is driven to slowly move backward along the lifting guide beam 14 under the coordinated traction of the first traction steel cable 12 and the second traction steel cable 45. During the backward movement of the transverse trolley 8 along the length direction of the lifting guide beam 14, when the middle part of the transverse trolley 8 just reaches the longitudinal hollow card slot 20 position of the longitudinal guide slot column 11, the columnar telescopic head 28 of the transverse telescope 27 is controlled to extend outward until it is inserted into the longitudinal hollow card slot 20; thereby, the transverse trolley 8 and the longitudinal guide slot column 11 are synchronized in the horizontal direction; finally, the ejector rod 30 of the oblique ejector 29 is controlled to be completely retracted, and the upper end of the ejector rod 30 is lower than the lower end of the top support block 31, thereby realizing the unlocking of the longitudinal guide slot column 11. Figure 4As shown;

[0034] Step three, under the traction of the first traction steel cable 12 and the second traction steel cable 45, the lateral movement trolley 8 is driven to continue to slowly move backward along the lifting guide rail beam 14. At this time, the longitudinal guide groove column 11 is driven by the columnar telescopic head 28 and guided by a plurality of b guide wheels 22 to slowly move backward with the lateral movement trolley 8, so that the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are gradually tilted backward from the original vertical direction, and the lifting guide rail beam 14 is further lowered and moved to the right in a horizontal state until the lower end of the vertical guide wheel support 17 drops to the limit contact limit seat 21, so that the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are gradually tilted backward from the original vertical direction by 45°, so that the lifting guide rail beam 14 and the unloaded empty lateral movement trolley 8 are further lowered by h2 on the basis of the first drop h1; at the same time, the empty lateral movement trolley 8 is at the rear end position of the lifting guide rail beam 14; so that the lateral movement trolley 8 is just in the loading position at this time; in this state, the loading device can load goods to the lateral movement trolley 8;

[0035] Step 4, under the coordinated traction of the first traction steel cable 12 and the second traction steel cable 45, the traverse trolley 8 is driven to slowly move forward along the lifting guide rail beam 14, and the longitudinal guide groove column 11 is driven by the columnar telescopic head 28 and guided by a plurality of b guide wheels 22 and moves slowly forward with the traverse trolley 8, so that the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 gradually change from the original backward tilt to vertical, so that the traverse trolley 8 and the lifting guide rail beam 14 are synchronously moved forward and gradually rise, until the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 that were originally tilted backward just become vertical, the end of the limit arm 24 just contacts the limit end surface 26 of the transverse guide groove 25, at this time, the traverse trolley 8 and the lifting guide rail beam 14 have risen h2, and at the same time, the push rod 30 of the inclined pusher 29 is controlled to extend to the top of the top pressure support block 31 The top support surface 32 is pushed upward, thereby completely locking the longitudinal guide groove column 11; then the columnar telescopic head 28 of the transverse telescopic device 27 is controlled to retract from the longitudinal hollow card slot 20, so that the columnar telescopic head 28 is separated from the longitudinal guide groove column 11 in the completely locked state; then, the transverse trolley 8 is driven to continue to slowly move forward along the lifting guide rail beam 14 under the coordinated traction of the first traction steel cable 12 and the second traction steel cable 45, until the transverse trolley 8 reaches the front end of the lifting guide rail beam 14, and finally the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are controlled to extend upward, so that the transverse trolley 8 and the lifting guide rail beam 14 are further raised h1 on the basis of being raised h2, so that the transverse trolley 8 is just in the unloading position at this time; in this state, the unloading device can take away the goods loaded on the transverse trolley 8; a working cycle is completed at this point;

[0036] During the above process, the lifting and lowering interval of the lifting guide beam 14 and the transverse moving trolley 8 exceeds the telescopic stroke of the first telescopic cylinder 1 and the second telescopic cylinder 2, thereby changing the lifting and lowering interval from the original h1 to h1+h2; and the lowest height of the lifting guide beam 14 can be further reduced, thereby further reducing the height of the transverse moving trolley 8 during loading; at the same time, the total transverse stroke of the transverse moving trolley 8 also breaks through the length limit of the lifting guide beam 14 itself.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
