[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a heavy-load inclined shaft transportation equipment includes a track beam 8 located in an inclined shaft 7, and a transportation equipment steel device 6 is arranged above the track beam 8. The track beam 8 is a transportation workpiece of the transportation equipment steel device 6. A plurality of climbing load-bearing supports 10 are arranged on the inclined shaft crawling surface 11, and the spacing between adjacent climbing load-bearing supports 10 is 3m, and the bearing capacity of each climbing load-bearing support 10 is not less than 300t.

[0028] The track beam 8 is arranged on the supporting trolley 5 , and the supporting trolley 5 is provided with a lifting system and a crawling system, and both the lifting system and the crawling system are connected to the hydraulic station 23 .

[0029] The track beam 8 includes an upper beam body 16 and a lower beam body 17 which are fixedly connected together. Upper load-bearing supports 9 are arranged below the four corners of the upper beam body 16 , and at least two lower load-bearing supports 18 are arranged at the bottom of the lower beam body 17 .

[0030] Among them, the tops of the four upper load-bearing supports 9 jointly support the transport equipment steel equipment 6. Each of the upper load-bearing supports 9 is in an inverted trapezoidal shape. The bottom surface of the inverted trapezoidal upper load-bearing support 9 is set on the crawling load-bearing track 13 through the vertical lifting hydraulic cylinder 12. During assembly, a load-bearing bearing is set at the bottom of the output rod of the vertical lifting hydraulic cylinder 12. The vertical lifting hydraulic cylinder 12 is set on the crawling load-bearing track 13 through the load-bearing bearing, so that the four upper load-bearing supports 9 meet the center requirement of the track beam 8 itself. The inclined surface of the inverted trapezoidal upper load-bearing support 9 is connected to the inclined lifting hydraulic cylinder 14. The output shaft of the inclined lifting hydraulic cylinder 14 is against the support table on the top of the track beam 8. The top of the track beam 8 is provided with a support table that matches the shape of the output shaft of the inclined lifting hydraulic cylinder 14. The inclined lifting hydraulic cylinder 14 here constitutes a 50° vertical lifting system.

[0031] It should be noted that the track surface of the crawling load-bearing track 13 is lower than the inclined shaft crawling surface 11.

[0032] Furthermore, each upper load-bearing support 9 is connected to a transverse fine-tuning hydraulic cylinder 15 in the transverse direction, and the output shaft of the transverse fine-tuning hydraulic cylinder 15 abuts against the upper load-bearing support 9 .

[0033] Furthermore, the angle between the output shaft of the inclined surface lifting hydraulic cylinder 14 and the inclined shaft crawling surface 11 is 50°.

[0034] Furthermore, the cross-section of each climbing load-bearing support 10 is a right triangle, the right-angled side of the right triangle is in contact with the inclined shaft crawling surface 11, and the angle between the inclined surface of the right triangle and the inclined shaft crawling surface 11 is 50°.

[0035] The cross section of the lower load-bearing support 18 is also triangular, and it cooperates with the climbing load-bearing support 10 .

[0036] like Figure 3 As shown, the crawling system includes a front crawling mechanism and a rear crawling mechanism, which are symmetrically arranged. The rear crawling mechanism is taken as an example to explain its structure. The rear crawling mechanism includes a telescopic arm guide beam 22 fixed above the supporting trolley 5, and the cylinder body of the rear crawling hydraulic cylinder 24 is fixed on the telescopic arm guide beam 22. The output shaft of the crawling hydraulic cylinder 24 is hinged to the telescopic arm 21, and the telescopic arm 21 is connected to the telescopic support foot 20. The telescopic support foot 20 is slidably arranged on the telescopic support foot guide beam 19.

[0037] like Figure 3 As shown, the lifting system includes a lifting hydraulic cylinder 25, the cylinder body of the lifting hydraulic cylinder 25 is hinged on the telescopic support foot guide beam 19, and the output shaft of the lifting hydraulic cylinder 25 is connected to the telescopic support foot 20. It should be noted that the front crawling mechanism and the rear crawling mechanism are respectively connected to a corresponding lifting system.

[0038] Preferably, the front crawling mechanism and the rear crawling mechanism share a telescopic arm guide beam 22, and two supporting trolleys 5 are arranged below the telescopic arm guide beam 22, and the two supporting trolleys 5 correspond to the front crawling mechanism and the rear crawling mechanism respectively.

[0039] The working principle of the present invention is:

[0040] In the initial state, the transport equipment steel equipment 6 is supported by the track beam 8 , the track beam 8 is arranged on the telescopic arm guide beam 22 , the telescopic arm guide beam 22 is arranged on the support trolley 5 , and the support trolley 5 can drive the telescopic arm guide beam 22 to move.

[0041] When climbing a slope and crossing the climbing load-bearing support 10, the front crawling mechanism and the rear crawling mechanism do not climb the slope at the same time. When one climbs the slope, the other moves forward.

[0042] like Figure 4 , Figure 5 , Figure 6 As shown, when the rear crawling mechanism needs to crawl and climb the load-bearing support 10, the lifting system corresponding to the rear crawling mechanism works first, and the output shaft of the lifting hydraulic cylinder 25 retracts, driving the telescopic support foot 20 to lift upward, and at the same time driving the rear end of the telescopic arm guide beam 22 to lift through the telescopic arm 21. Since the track beam 8 is arranged on the telescopic arm guide beam 22, it is equivalent to lifting the rear end of the track beam 8, and the front end of the track beam 8 does not move.

[0043] At this time, the output shaft of the rear crawling hydraulic cylinder 24 begins to extend, and the rear crawling hydraulic cylinder 24 drives the corresponding supporting trolley 5 to move forward, so that the telescopic arm guide beam 22 and the track beam 8 above it move forward together. Since the rear end of the track beam 8 has been lifted, it is convenient for the supporting trolley 5 to climb over the climbing load-bearing support 10. After climbing, the lower load-bearing support 18 at the lower end of the track beam 8 rests against the right-angled edge of the climbing load-bearing support 10 to prevent sliding backward.

[0044] Next, the rear crawling hydraulic cylinder 24 of the rear crawling mechanism is actuated, causing the output shaft of the rear crawling hydraulic cylinder 24 to retract, driving the telescopic supporting foot 20 and the telescopic supporting foot guide beam 19 to move forward together.

[0045] The crawling and forward moving action processes of the front crawling mechanism are the same and will not be described in detail here.

[0046] In addition, when the front end or rear end of the track beam 8 is lifted (when climbing a slope), the inclined plane lifting hydraulic cylinder 14 does not work. When the track beam 8 moves forward, the inclined plane lifting hydraulic cylinder 14 plays an auxiliary supporting role.

[0047] In summary, the present invention realizes the functions of self-loading, precise alignment, automatic positioning, and progressive climbing of the slope, and can provide power supply from the middle of the inclined shaft to meet the operation of equipment with an installed capacity of not less than 600kW.

[0048] The present invention has the ability to carry a 390t track beam 8, and is equipped with a 50° vertical lifting system, a vertical lifting system and a lateral fine-tuning system to realize the functions of self-loading, precise positioning and automatic positioning. It is equipped with a climbing system to realize a progressive climbing of a 50° slope through the lifting and pulling of the support and the cooperation of the jacking hydraulic cylinder. The vehicle power system is powered by a 380V50Hz power supply, and the equipment is equipped with two sets of hydraulic stations 23 to provide power to the execution system. The equipment weighs about 200t.

[0049] The invention has a heavy-load climbing speed of about 2 m / min and an unloaded descending speed of about 6 m / min, and an average of about 8-12 hours can be used to erect a track beam 8. If the efficiency cannot meet the on-site requirements, a method of simultaneously erecting multiple devices can be used to meet the efficiency requirements.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
