[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figures 1 to 4As shown, a transport device for aluminum coils includes a transport body 1, a carrying mechanism 2 and a lifting mechanism 3. The transport body 1 is slidably arranged above a pit. Generally, a pit is provided on the foundation of a work site. The carrying mechanism 2 is slidably arranged on the transport body 1 through the lifting mechanism 3 and is used to carry the aluminum coil 5. The lifting mechanism 3 includes a secondary hydraulic cylinder 31 and a plurality of double-layer nested guide pillars 32. The secondary hydraulic cylinder 31 is fixedly arranged on the transport body 1. The plurality of double-layer nested guide pillars 32 are uniformly slidably arranged on the transport body 1. The second-stage cylinder rod 313 of the secondary hydraulic cylinder 31 and the plurality of double-layer nested guide pillars 32 are uniformly slidably arranged on the transport body 1. The top of 32 is evenly and fixedly connected to the bearing mechanism 2; the transport device also includes a walking mechanism 4, the walking mechanism 4 includes a fixed rail 41, a driving motor 42 and a plurality of walking wheels 43 matching the fixed rail 41, the fixed rail 41 is fixedly set on both sides of the pit, specifically, the fixed rail 41 is fixed on both sides of the pit by nuts and bolts, and the plurality of walking wheels 43 are evenly and rotatably set on the transport body 1, the output shaft of the driving motor 42 is fixedly connected to two opposite walking wheels 43 through a reducer, and the plurality of walking wheels 43 are slidably connected to the fixed rail 41. Among them, the rotation methods of the walking wheels 43 are all existing technologies, and no further explanation is given here. The walking wheels 43 in this embodiment are rotatably set on the transport body 1 using bearings; the walking wheels 43 in this embodiment are set to 4, and the number of walking wheels 43 is not limited, and can be 2, 6, 8, etc.

[0027] When the transport vehicle body 1 of this embodiment is in the process of sliding, the secondary hydraulic cylinder 31 and the double-layer nested guide pillars 32 are in a retracted state; when the transport vehicle body 1 stops sliding and is in the process of connecting the aluminum coil 5, the secondary hydraulic cylinder 31 and the double-layer nested guide pillars 32 are in an extended state. When the secondary hydraulic cylinder 31 is activated, it can drive the double-layer nested guide pillars 32 and the bearing mechanism 2 to slide upward or downward. Generally, when the secondary hydraulic cylinder 31 is activated, it will first drive the double-layer nested guide pillars 32 and the bearing mechanism 2 to slide upward. After the bearing mechanism 2 fixes the aluminum coil 5, the secondary hydraulic cylinder 31 will then drive the double-layer nested guide pillars 32 and the bearing mechanism 2 to slide downward.

[0028] When the secondary hydraulic cylinder 31 and the double-layer nested guide pillar 32 are in a retracted state, they are located in the pit; when the secondary hydraulic cylinder 31 and the double-layer nested guide pillar 32 are in an extended state, they are located above the pit. The operating stroke of the secondary hydraulic cylinder 31 and the double-layer nested guide pillar 32 of this embodiment is relatively small.

[0029] The driving motor 42 is started, driving the two traveling wheels 43 fixedly connected thereto to rotate, thereby driving the multiple traveling wheels 43 to rotate. The rotating multiple traveling wheels 43 slide on the fixed track 41, and finally the transport body 1 and the aluminum coil 5 thereon slide, thereby realizing the automated transportation of the aluminum coil 5.

[0030] The transport device of this embodiment adopts a two-stage hydraulic cylinder 31 and a double-layer nested guide column 32. The two-stage hydraulic cylinder 31 replaces the single-stage hydraulic cylinder of the traditional transport trolley. The two-stage hydraulic cylinder 31 not only runs more stably, but also has a reduced running stroke; the double-layer nested guide column 32 replaces the fixed guide column on the traditional transport trolley (the installation stroke of the fixed guide column on the single-stage hydraulic cylinder is longer), and the double-layer nested guide column 32 can also slide with the two-stage hydraulic cylinder 31, and the running stroke is also reduced. The running stroke of the two-stage hydraulic cylinder 31 and the double-layer nested guide column 32 is reduced, thereby reducing the depth of the pit, thereby reducing the risk of personal injury accidents caused by people falling into the pit. The drive motor 42 is started, driving the walking wheel 43, the transport body 1 and the aluminum coil 5 thereon to slide, thereby realizing the automatic transportation of the aluminum coil 5, replacing the manual transfer of the transport trolley and the aluminum coil 5, and effectively improving the transportation efficiency of the aluminum coil 5.

[0031] As an implementation method, the bearing mechanism 2 includes a bearing bracket 21 and a plurality of bearing rollers 22 for fixing the aluminum coil 5. The plurality of bearing rollers 22 are evenly fixedly arranged on the top of the bearing bracket 21. Specifically, the bearing rollers 22 are also fixedly arranged on the top of the bearing bracket 21 by nuts and bolts. The second-stage cylinder rod 313 of the secondary hydraulic cylinder 31 and the top of the double-layer nested guide pillars 32 are fixedly connected to the bottom of the bearing bracket 21; the second-stage cylinder rod 313 of the secondary hydraulic cylinder 31 and the top of the plurality of double-layer nested guide pillars 32 can be fixedly connected to the bottom of the bearing bracket 21 by welding or by nuts and bolts. In this embodiment, two bearing rollers 22 are provided, and the two bearing rollers 22 are relatively arranged on the top of the bearing bracket 21. Usually, the aluminum coil 5 is placed above the two bearing rollers 22 to maintain stability.

[0032] As an implementation method, each of the double-layer nested guide pillars 32 includes a sleeve 321 and a guide pillar 322, the guide pillar 322 is slidably arranged in the sleeve 321, one end of the guide pillar 322 is fixedly connected to the bearing mechanism 2, and the transport vehicle body 1 is evenly provided with a plurality of through holes of the same number as the double-layer nested guide pillars 32, each of the through holes is provided with a sliding sleeve, one end of the sleeve 321 passes through the sliding sleeve and is interference fit with the sliding sleeve. In this embodiment, two double-layer nested guide pillars 32 are provided, and the secondary hydraulic cylinder 31 is located between the two double-layer nested guide pillars 32.

[0033] When the secondary hydraulic cylinder 31 is started, driving the double-layer nested guide column 32 to slide upward, that is, driving the guide column 322 to slide out of the sleeve 321, the sleeve 321 and the guide column 322 are in an extended state, and the sleeve 321 will not completely slide out of the guide column 322. At this time, the sleeve 321 and the guide column 322 are both located above the pit.

[0034] When the secondary hydraulic cylinder 31 is started, the double-layer nested guide pillars 32 are driven to slide downward, that is, the guide pillars 322 are driven to fully extend into the sleeve 321, and the sleeve 321 and the guide pillars 322 are in a retracted state. At this time, the sleeve 321 and the guide pillars 322 are both located in the pit, and the running stroke is relatively small. Since the movement stroke of the secondary hydraulic cylinder 31 is fixed and the sliding sleeve limits the guide pillars 322, the extended positions of the sleeves 321 and the guide pillars 322 are limited, so as to prevent the sleeves 321 and the guide pillars 322 from detaching from the transport vehicle body 1.

[0035] As an implementable embodiment, the secondary hydraulic cylinder 31 includes a main cylinder body 311, a first-stage cylinder rod 312 and a second-stage cylinder rod 313. An opening is provided at the center position of the transport body 1. The main cylinder body 311 is fixedly arranged at the opening and the main cylinder body 311 is located below the transport body 1. A main cylinder barrel is provided on the main cylinder body 311, and the first-stage cylinder rod 312 is slidably arranged in the main cylinder barrel. A first cylinder barrel is provided on the first-stage cylinder rod 312, and the second-stage cylinder rod 313 is slidably arranged in the first cylinder barrel.

[0036] The secondary hydraulic cylinder 31 is started, driving the first cylinder rod 312 to slide out from the main cylinder barrel and the second cylinder rod 313 to slide out from the first cylinder barrel. The first cylinder rod 312 and the second cylinder rod 313 are in an extended state. At this time, the first cylinder rod 312 and the second cylinder rod 313 are both located above the pit.

[0037] The secondary hydraulic cylinder 31 is started, driving the first-stage cylinder rod 312 to extend into the main cylinder barrel and the second-stage cylinder rod 313 to extend into the first cylinder barrel. The first-stage cylinder rod 312 and the second-stage cylinder rod 313 are in a retracted state. At this time, the first-stage cylinder rod 312 and the second-stage cylinder rod 313 are both located in the pit, and the operating stroke is relatively small.

[0038] As an implementation method, the driving motor 42 is arranged on the fixed transport vehicle body 1; an inner groove is arranged on the transport vehicle body 1, and a plurality of the traveling wheels 43 are evenly rotated and arranged in the inner groove, and the fixed track 41 is slidably connected with the plurality of traveling wheels 43. The inner groove not only avoids the position of the traveling wheels 43, making the overall structure more streamlined, but also guides the traveling wheels 43, so that the traveling wheels 43 can only slide along the fixed track 41.

[0039] As an implementation method, a protective cover 411 is further provided on the fixed track 41. The provision of the protective cover 411 does not affect the sliding of the traveling wheel 43 on the fixed track 41. The protective cover 411 mainly protects the portion of the fixed track 41 that is not slidably connected to the traveling wheel 43. The protective cover 411 effectively prevents droplets or small particles from entering the fixed track 41, being sandwiched between the fixed track 41 and the traveling wheel 43, and affecting the sliding of the transport device.

[0040] The process of transporting the aluminum coil 5 by the transport device of this embodiment is as follows: the secondary hydraulic cylinder 31 is started, driving the first-stage cylinder rod 312 to slide out from the main cylinder barrel, the second-stage cylinder rod 313 to slide out from the first cylinder barrel, and the guide column 322 to slide out from the sleeve 321, and the first-stage cylinder rod 312, the second-stage cylinder rod 313, the sleeve 321 and the guide column 322 are in an extended state. When the aluminum coil 5 is placed above the two load-bearing rollers 22, the secondary hydraulic cylinder 31 drives the first-stage cylinder rod 312 to extend into the main cylinder barrel, the second-stage cylinder rod 313 to extend into the first cylinder barrel, and the guide column 322 to fully extend into the sleeve 321, and the first-stage cylinder rod 312, the second-stage cylinder rod 313, the sleeve 321 and the guide column 322 are in a retracted state. Figure 2 , and the arrow indicates the sliding direction of the transport vehicle body 1. The driving motor 42 is started, driving the two running wheels 43 fixedly connected thereto to rotate, thereby driving the multiple running wheels 43 to rotate, and the rotating multiple running wheels 43 slide on the fixed rail 41, and finally the transport vehicle body 1 and the aluminum coil 5 thereon slide, thereby realizing the automatic transportation of the aluminum coil 5.
