The end of the first traction cable 12 is fixedly connected to the rear end of the transverse trolley 8; the end of the second traction cable 45 is fixedly connected to the front end of the transverse trolley 8; the transverse trolley 8 moves along the length of the lifting guide beam 14 under the combined traction of the first traction cable 12 and the second traction cable 45. In this case, both the first traction cable 12 and the second traction cable 45 are driven by hydraulic winches, which move up and down synchronously with the lifting guide beam 14.

[0025] In the first embodiment, the lower end of the longitudinal guide column 11 is fixed to the horizontal fixed beam 15, and the longitudinal guide column 11 is a fixing member.

[0026] The first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 have a telescopic stroke h1. In the first embodiment, the lifting range of the lifting rail beam 14 and the horizontal moving trolley 8 is strictly limited by the telescopic stroke of the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2, so that the lifting range cannot exceed h1. The lowest height of the lifting rail beam 14 is affected by the length of the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 in the retracted state, so that the lifting rail beam 14 cannot be lowered to a lower position in the initial position, thereby limiting the feeding height of the horizontal moving trolley 8. At the same time, the horizontal moving stroke of the horizontal moving trolley 8 is strictly limited by the length of the lifting rail beam 14, so that the total horizontal moving stroke of the horizontal moving trolley 8 cannot exceed the length L of the lifting rail beam 14. Therefore, the second embodiment is designed on the basis of the first embodiment.

[0027] The longitudinal guide groove column 11 of the second embodiment is a non-fixed member, as shown in Figure 2 、 3 , the side of the rear section of the horizontal fixed beam 15 is provided with a transverse guide groove 25 along the length direction, and the front end of the transverse guide groove 25 is provided with a limiting end face 26. A transverse guide wheel support 23 is arranged in the transverse guide groove 25, and a plurality of b guide wheels 22 arranged in the transverse direction are rotatably mounted on the transverse guide wheel support 23 through bearings. The b guide wheels 22 are clamped in the transverse guide groove 25 and are in rolling contact with the lower inner wall of the transverse guide groove 25, and are in clearance fit with the upper inner wall of the transverse guide groove 25. A limiting seat 21 is fixedly installed on the upper side of the transverse guide wheel support 23, and the lower end of the longitudinal guide groove column 11 is fixedly connected to the limiting seat 21. The lower end of the vertical guide wheel support 17 extends downward to below all a guide wheels 18. When the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are both vertically and both retracted downward, the distance between the lower end of the vertical guide wheel support 17 and the limiting seat 21 is h2, which is less than the length of the first telescopic oil cylinder 1 or the second telescopic oil cylinder 2 in the retracted state.

[0028] The front end of the transverse guide wheel support 23 is provided with a limiting arm 24 extending forward. The bottom of the longitudinal guide groove 10 of the longitudinal guide groove column 11 extends a longitudinal hollow clamping groove 20 in the longitudinal direction. A horizontal telescoping device 27 is fixedly installed on the middle of the side of the horizontal moving trolley 8 close to the longitudinal guide groove column 11, and the telescoping direction of the cylindrical telescoping head 28 of the horizontal telescoping device 27 is perpendicular to the extension direction of the lifting rail beam 14. The outer diameter of the cylindrical telescoping head 28 is not greater than the groove width of the longitudinal hollow clamping groove 20. During the running of the horizontal moving trolley 8 along the length direction of the lifting rail beam 14, when the middle of the horizontal moving trolley 8 reaches the position of the longitudinal hollow clamping groove 20 of the longitudinal guide groove column 11, the cylindrical telescoping head 28 of the horizontal telescoping device 27 can be extended to be clamped into the longitudinal hollow clamping groove 20. In order to reduce the friction, the cylindrical telescoping head 28 is sleeved with a sliding ring.

[0029] The rear side of the upper end of the longitudinal guide slot column 11 is fixedly provided with a rearward and upward extending inclined pusher 29, the push rod 30 of the inclined pusher 29 is provided with a fixed arm 33 upward and obliquely, the fixed arm 33 is fixed on the fixed device; the lower end of the fixed arm 33 is integrally connected with a jacking block 31, the side close to the push rod 30 of the jacking block 31 is provided with a jacking surface 32 parallel to the end surface of the push rod 30; when the limit end of the limit arm 24 limitingly contacts the limit end surface 26 of the horizontal guide slot 25, the push rod 30 of the inclined pusher 29 can be obliquely extended to the jacking surface 32 of the jacking block 31; when the push rod 30 of the inclined pusher 29 is completely retracted, the upper end of the push rod 30 is lower than the lower end of the jacking block 31.

[0030] Working principle: The overall working process: the horizontal moving trolley 8 runs to the front end of the lifting guide rail beam 14, and then rises to the highest position, and then the unloading device takes away the loaded goods on the horizontal moving trolley 8; then the empty horizontal moving trolley 8 needs to run to the rear end of the lifting guide rail beam 14, and then descend to the lowest position, and then the loading device loads goods to the horizontal moving trolley 8; so as to run back and forth, so that the horizontal moving trolley 8 continuously transports goods from a place to a farther and higher place b.

[0031] Detailed process of the second embodiment:

[0032] Step one, in the initial state, the limit end of the limit arm 24 limitingly contacts the limit end surface 26 of the horizontal guide slot 25, and the push rod 30 of the inclined pusher 29 extends to the jacking surface 32 of the jacking block 31, so that the position of the longitudinal guide slot column 11 is locked; at this time, the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are in vertical state under the constraint of the locked longitudinal guide slot column 11; in the initial state, the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are in the state of extending upward, and the horizontal moving trolley 8 is at the front end of the lifting guide rail beam 14, so that the horizontal moving trolley 8 is just in the unloading position at this time; in this state, the unloading device can take away the loaded goods on the horizontal moving trolley 8;

[0033] Step two, first, the first telescopic oil cylinder 1 and the second telescopic oil cylinder 2 are synchronously retracted, so that the lifting guide rail beam 14 and the unloaded empty horizontal moving trolley 8 are jointly lowered for the first time h1, and then the horizontal moving trolley 8 is slowly displaced backward along the lifting guide rail beam 14 under the cooperation of the first traction steel cable 12 and the second traction steel cable 45, in the process of running backward along the length direction of the lifting guide rail beam 14, when the middle part of the horizontal moving trolley 8 reaches the position of the longitudinal hollow clamping groove 20 of the longitudinal guide slot column 11, the cylindrical telescopic head 28 of the horizontal telescoping device 27 is controlled to extend outward to be clamped into the longitudinal hollow clamping groove 20; so that the horizontal moving trolley 8 and the longitudinal guide slot column 11 are synchronized in the horizontal direction; finally, the push rod 30 of the inclined pusher 29 is controlled to be completely retracted, and the upper end of the push rod 30 is lower than the lower end of the jacking block 31, so as to realize the unlocking of the longitudinal guide slot column 11, like Figure 4As shown;

[0034] Step 3: Under the combined traction of the first traction cable 12 and the second traction cable 45, the transverse trolley 8 continues to move slowly backward along the lifting guide beam 14. At this time, the longitudinal guide column 11, driven by the column telescopic head 28 and guided by several guide wheels 22, moves slowly backward along with the transverse trolley 8, causing the first telescopic cylinder 1 and the second telescopic cylinder 2 to gradually tilt backward from their original vertical position. The lifting guide beam 14 further descends and moves to the right in a horizontal state until the lower end of the vertical guide wheel support 17 descends to the limit contact limit seat 21, causing the first telescopic cylinder 1 and the second telescopic cylinder 2 to gradually tilt backward by 45° from their original vertical position. Thus, the lifting guide beam 14 and the unloaded empty transverse trolley 8 further descend by h2 on the basis of the first descent h1. At the same time, the empty transverse trolley 8 is at the rear end of the lifting guide beam 14, so that the transverse trolley 8 is just at the loading position. In this state, the loading device can load goods onto the transverse trolley 8.

[0035] Step four: Under the combined traction of the first traction cable 12 and the second traction cable 45, the lateral trolley 8 slowly moves forward along the lifting guide beam 14. The longitudinal guide column 11, driven by the columnar telescopic head 28 and guided by several guide wheels 22, also slowly moves forward with the lateral trolley 8. This causes the first telescopic cylinder 1 and the second telescopic cylinder 2 to gradually change from their original backward tilt to a vertical position. Simultaneously, the lateral trolley 8 and the lifting guide beam 14 move forward synchronously and gradually rise until the first telescopic cylinder 1 and the second telescopic cylinder 2, which were originally tilted backward, just become vertical. At this point, the end of the limiting arm 24 just contacts the limiting end face 26 of the transverse guide groove 25. At this time, the lateral trolley 8 and the lifting guide beam 14 have risen by h2. At the same time, the pushing rod 30 of the inclined pusher 29 extends to the top support block 31. The top support surface 32 is used to completely lock the longitudinal guide column 11; then the cylindrical telescopic head 28 of the transverse telescopic device 27 is controlled to retract from the longitudinal hollow slot 20, thereby separating the cylindrical telescopic head 28 from the longitudinal guide column 11 in the fully locked state; subsequently, under the combined traction of the first traction steel cable 12 and the second traction steel cable 45, the transverse trolley 8 continues to move slowly forward along the lifting guide beam 14 until the transverse trolley 8 reaches the front end of the lifting guide beam 14, and finally the first telescopic cylinder 1 and the second telescopic cylinder 2 are both controlled to extend upward, thereby raising the transverse trolley 8 and the lifting guide beam 14 by h1 on the basis of already being raised by h2, so that the transverse trolley 8 is just in the unloading position at this time; in this state, the unloading device can remove the goods loaded on the transverse trolley 8; thus, one work cycle is completed;

[0036] During the above process, the lifting range of the lifting guide beam 14 and the transverse trolley 8 exceeds the extension stroke of the first telescopic cylinder 1 and the second telescopic cylinder 2, thereby changing the lifting range from the original h1 to h1+h2; and further reducing the minimum height of the lifting guide beam 14, thereby further reducing the height of the transverse trolley 8 when loading materials; at the same time, the total transverse stroke of the transverse trolley 8 also exceeds the length limit of the lifting guide beam 14 itself.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
