Description

Technical Field

[0001] The invention relates to the technical field of hoisting equipment, and in particular to a hoisting machine. Background Art

[0002] At port terminals, railway freight stations, and logistics container yards, container reach stackers are often used as heavy-duty container loading and unloading equipment. Ordinary reach stackers have the function of lifting multiple rows of containers in sequence and limited cross-row lifting capabilities, but they are unable to lift containers below one layer across the container. Even if an overhead lifting device is added, it can only lift two layers of containers, and it is even more impossible to perform longitudinal lifting and stacking operations for 40-foot containers above the second floor and 20-foot containers above the third floor. There are also requirements for lifting containers across rails and vertical lifting at railway container freight stations, and conventional reach stackers often cannot meet these requirements.

[0003] In addition, with the successful launch of large-scale automated container terminals and yards, and the high labor costs, the industry is in urgent need of low-cost automated stacking and lifting equipment and control systems for small and medium-sized container yards. If a small yard uses large gantry cranes from large automated terminals for automated operations, the price of a single automated gantry crane ARMG or ARTG is as high as 10 million yuan, plus the cost of track and foundation construction, the equipment cost alone will be as high as 12 million yuan. Ordinary customers cannot afford such high equipment procurement costs.

[0004] With the popularization and rapidity of logistics container outlets, small container railway freight stations and inland shipping terminals are increasing year by year. If the conventional inland terminal construction requirements are followed, it is generally necessary to purchase small shore-to-ship gantry cranes (STS) for shore-to-ship container loading and unloading, and also to purchase reach stackers or RMGs for container stacking operations. With this equipment configuration plan, the total purchase cost of the equipment alone is as high as more than 12 million. Summary of the invention

[0005] The purpose of the present application is to provide a lifting machine that can cross multiple rows of containers to perform unloading and lifting operations on target containers, thereby simplifying the unloading process. The machine can also be used at inland river terminals to replace quay cranes and can be used as the preferred automated operating equipment for container yards, thereby improving operating efficiency and saving costs.

[0046] See also Figures 1 to 7 As shown, the embodiment of the present application provides a hoisting machine, comprising: a frame 1, a pitch mechanism 2 and a vertical lifting mechanism 3. The pitch mechanism 2 comprises a pitch arm 21, and the pitch arm 21 is movably connected to the frame. The vertical lifting mechanism 3 is connected to the pitch arm 21 in a transmission manner, and a hoist 9 is connected to the end of the vertical lifting mechanism 3.

[0047] In the embodiment of the present application, the hoisting machine is provided with two power mechanisms, namely a pitching mechanism 2 and a vertical lifting mechanism 3. The pitching mechanism 2 is fixed after changing its amplitude to the maximum height, and is switched to the vertical lifting mechanism 3 to perform vertical lifting operations, thereby reducing the energy consumption of the pitching mechanism 2 and reducing the fuel consumption / electricity consumption of the hoisting box lifting operation by 10%-30%. At the same time, the coordinated operation of the pitching mechanism 2 and the vertical lifting mechanism 3 can span multiple rows of multi-layer containers and perform full-elevation heavy container stacking operations. The hoisting machine has a simple structure and low cost, and can span multiple rows of containers to perform unloading and lifting operations on the target container, thereby simplifying the unloading process, improving operation efficiency, and saving costs.

[0048] Among them, see Figures 1 to 3 As shown, a steering mechanism 22 is provided at one end of the luffing boom 21 away from the frame, and the vertical lifting mechanism 3 includes a winch 31 and a wire rope 32. The winch 31 is provided on the frame, one end of the wire rope 32 is connected to the winch 31, and the other end is wound around the steering mechanism 22 and droops naturally, and the bottom end is connected to the sling 9. Specifically, a movable pulley 8 is connected to the bottom end of the wire rope 32, and the sling is connected to the movable pulley 8. During the pitching movement of the luffing boom 21, part of the structure of the vertical lifting mechanism 3 can be driven to move synchronously. The working end of the vertical lifting mechanism 3 is located at the target position, which is convenient for performing the lifting operation.

[0049] The steering mechanism 22 may include a second fixed pulley 221. The steel wire rope 32 naturally droops after passing through the second fixed pulley 221. The provision of the second fixed pulley 221 is beneficial to reducing the lifting resistance of the steel wire rope.

[0051] See also Figure 1 As shown, in a possible implementation scheme, the pitch mechanism 2 further includes a support frame 23 and a luffing cylinder 24, wherein the support frame 23 and the luffing cylinder 24 are both connected to the vehicle frame 1, and the support frame 23 and the luffing cylinder 24 are both hinged to the luffing boom 21. The telescopic movement of the luffing cylinder 24 drives the pitching boom 21. Among them, the support frame 23 is fixed in position and can serve as a fulcrum of the luffing boom 21. A first articulated seat is provided on the support frame 23, and the luffing boom 21 is connected to the first articulated seat. The luffing boom 21 can rotate around the first articulated seat. The telescopic movement of the luffing cylinder 24 can drive the luffing boom 21 to rotate around the first articulated seat to adjust the pitch angle. Among them, after the luffing cylinder 24 is telescoped to the target position, it is fixed and the position of the luffing boom 21 is locked. At this time, it is only necessary to control the operation of the vertical lifting mechanism 3 to lift the cargo box. In this process, since the height position of the luffing boom 21 is fixed, there will be no energy consumption for the amplitude change of the front crane boom, and the fuel consumption / electricity consumption of the lifting operation of the hanging box can be reduced by 10%-30%.

[0052] See also Figure 1As shown, in a possible implementation, the support frame 23 includes a main support 231 and an oblique support 232. One end of the main support 231 is hinged to the frame 1, and the other end is hinged to the pitch boom 21. One end of the oblique support 232 is hinged to the main support 231, and the other end of the oblique support 232 is hinged to the frame 1. The main support 231, the oblique support 232 and the frame 1 form a triangular stable structure, which can form a stable fulcrum.

[0053] The support frame 23 may be a truss structure, that is, the main support 231 has two support arms arranged at intervals and a crossbeam connecting the two support arms, the first hinged seat is arranged at the ends of the two support arms, and the second hinged seat is arranged near the ends of the two support arms, and the diagonal braces 232 may include two, and the two diagonal braces 232 are connected to the second hinged seat at one end and hinged to the frame at the other end. Both support arms are hinged to the frame. The two first hinged seats can be hinged to the pitch boom 21 through a rotating shaft. This truss structure design increases the structural strength and can stably support the pitch boom 21.

[0054] See also Figure 1 As shown, in a possible implementation, the luffing boom 21 includes a basic arm 211, a telescopic arm 212 and a telescopic cylinder 213. The basic arm 211 has a telescopic cavity, one end of the telescopic arm 212 is connected to the telescopic cavity, the telescopic cylinder 213 is arranged in the telescopic cavity, and the two ends of the telescopic cylinder 213 are respectively connected to the basic arm 211 and the telescopic arm 212. The telescopic cylinder 213 telescopes and drives the telescopic arm 212 to translate along the length direction of the basic arm 211 to achieve extension or shortening.

[0055] The basic arm 211 is hinged to the support frame 23 and the amplitude-changing cylinder 24 respectively.

[0056] In a possible implementation, the vertical lifting device includes a plurality of steel wire ropes 32, the hoist 31 includes a plurality of winding drums, one end of each steel wire rope 32 is connected to a corresponding winding drum, and the other end is connected to the sling 9 through the steering mechanism 22. By providing a plurality of steel wire ropes 32, the load is shared, the safety is improved, and the plurality of steel wire ropes 32 improves the stability of the lifting process.

[0057] See also Figures 1 to 3As shown, in a possible embodiment, the hoisting machine further includes an anti-sway mechanism 4, the anti-sway mechanism 4 is connected to the pitch boom 21, the anti-sway mechanism 4 has a wire rope positioning device 41, the wire rope positioning device 41 is limited to the side of the wire rope 32, limits the position of the wire rope 32, and prevents the wire rope 32 from shaking. In the present application, the lifting device 9 is controlled to rise and fall by reeling in and out the wire rope 32, and the anti-sway mechanism 4 is used to prevent the lifting device 9 from swinging, thereby realizing the vertical traction operation of the lifting device 9.

[0058] See also Figures 1 to 3 As shown, in a possible implementation, the anti-sway mechanism 4 includes a telescopic device, the steel wire rope positioning device 41 is connected to the telescopic device, and the telescopic device drives the steel wire rope positioning device 41 to move up and down. In this implementation, when the steel wire rope 32 is lowered to the sling 9, the telescopic device can drive the steel wire rope positioning device 41 to descend synchronously, so that the length of the steel wire rope 32 in a free state is small, achieving an anti-sway effect. When the steel wire rope 32 is lifting the cargo box, the telescopic device is retracted synchronously and does not block the lifting of the cargo box. And the function of limiting the steel wire rope 32 is maintained.

[0059] The telescopic device includes a telescopic link assembly 42 and an adjusting cylinder 43. The telescopic link assembly 42 includes a plurality of link groups, each link group includes two cross-arranged movable links 422, and the movable links 422 of two adjacent link groups are hinged. The two ends of the adjusting cylinder 43 are respectively connected to the two movable links 422 of the same link group. The adjusting cylinder 43 telescopes and moves, driving the telescopic link assembly 42 to extend or shorten.

[0060] In the above scheme, when the adjustment cylinder 43 is extended, the two movable links 422 are driven to open at a larger angle, and the entire telescopic link assembly 42 is shortened. When the adjustment cylinder 43 is shortened, the two movable links 422 can be driven to reduce the opening angle, and the length of the entire telescopic link assembly 42 is increased.

[0061] In a possible embodiment, the wire rope positioning device 41 may include a guide sleeve 413, and the wire rope 32 is arranged through the guide sleeve 413. For example, the wire rope positioning device 41 is provided with a plurality of guide sleeves 413 along the length direction, and each wire rope 32 is respectively provided through the corresponding guide sleeve 413. The wire rope positioning device 41 may include a horizontal portion 411 and a vertical portion 412, a horizontal guide groove is provided on the horizontal portion 411, a plurality of guide sleeves 413 are provided on the horizontal portion 411 along the length direction, and a vertical guide groove is provided on the vertical portion 412. A first guide column is provided at the hinge axis of two cross-arranged movable links 422 of a connecting rod group of the telescopic connecting rod assembly 42, and a second guide column is provided at the end of each of the two movable links 422. Both the second guide columns are plugged into the horizontal guide groove, and the first guide column is plugged into the vertical guide groove. In this way, during the telescopic movement of the telescopic connecting rod assembly 42, the wire rope positioning device 41 remains stable and does not tilt, ensuring that each wire rope 32 remains vertical.

[0062] Among them, see Figure 2 and Figure 3 As shown, two movable links 422 of a group of links at the top of the telescopic link assembly 42 are respectively connected to a connecting bar 421, and one end of each of the two connecting bars 421 is hinged to the corresponding movable link 422. The other ends of the two connecting bars 421 are connected to the pitch boom 21 through a rotating shaft, for example, they can be connected to the steering mechanism 22 at the end of the pitch boom 21. A bracket and a plurality of second fixed pulleys are provided on the steering mechanism 22, and the other ends of the two connecting bars 421 are connected to the bracket through a rotating shaft. In this way, during the telescopic movement of the telescopic link assembly 42, the two connecting bars 421 can rotate around the rotating shaft.

[0063] In another possible embodiment, the wire rope positioning device 41 includes a roller group, each of which includes two rollers, and the wire rope 32 is clamped between the two rollers. The wire rope positioning device 41 may include a triangular bracket, which is connected to the rotating shafts of two movable connecting rods of a connecting rod group, and the triangular bracket has a bottom edge and two oblique edges connecting the bottom edge, and multiple roller groups can be arranged on the bottom edge along the length direction. Each roller group is used to clamp and limit a wire rope 32.

[0064] See also Figure 1 and Figure 7 As shown, in a possible embodiment, the frame includes a front frame 11 and a rear frame 12, the front frame 11 has a cavity, and one end of the rear frame 12 is slidably connected to the cavity to adjust the length of the hoisting machine. The hoisting machine has a variable wheelbase rear frame 12. When the container spreader 9 is loaded and extended forward, and the whole vehicle is in a forward unstable state, the rear frame 12 can be controlled to extend backward to change the wheelbase, increase the longitudinal stability torque of the whole vehicle, and enable the equipment to obtain a greater lifting capacity.

[0065] The front frame 11 may include two main boxes spaced apart from each other, each of the two main boxes being provided with a cavity, and the rear frame 12 may be provided with two telescopic beams correspondingly, and the two telescopic beams of the rear frame 12 are respectively connected to the cavities of the two main boxes.

[0066] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, two slewing bridges 5 are movably connected to the frame 1, and wheels 7 are arranged on the slewing bridges 5. A telescopic device 6 is arranged between the frame and the slewing bridge 5, and the telescopic device 6 can drive the slewing bridge 5 to swing so as to adjust the wheel track of the wheels. The telescopic device 6 can be a telescopic cylinder, one end of which is connected to the frame and the other end is connected to the slewing bridge 5. The telescopic movement of the telescopic cylinder can drive the slewing bridge 5 to swing. For example, when the hoist needs to be transported, the telescopic cylinder can be controlled to drive the slewing bridge 5 to swing until it is stored in the front part of the frame, thereby reducing the wheel track of the front wheels and saving space.

[0067] The slewing bridge 5 is provided at least at the front of the vehicle frame 1. The front wheel is provided on the slewing bridge 5. The slewing bridge 5 is provided with a slewing motor 52 and a slewing support seat 51. The slewing support seat 51 includes a swing bearing 53 and a slewing support. The swing bearing 53 is connected to the slewing bridge 5. The slewing support is rotatably connected to the swing bearing 53. The wheel 7 is connected to the slewing support. The wheel 7 can roll relative to the slewing support. The slewing motor 53 is connected to the slewing support by transmission to drive the slewing support to rotate so as to adjust the driving direction of the wheel. The slewing motor 52 can drive the front wheel to slew and turn in situ, and perform complex steering actions such as 90-degree head-turning. The front wheel 7 has an independent driving mechanism, and the driving mechanism is connected to the front wheel by transmission to drive the front wheel to roll. The slewing motor 52 adjusts the driving direction of the front wheel, and the lateral driving of the hoist can be realized in cooperation with the driving mechanism. Among them, the rotary motor 52 may include a motor and a worm, the rotary support is provided with meshing teeth along the circumferential direction, the worm and the rotary support are meshed, the motor drives the worm to rotate and then drives the rotary support to rotate, and finally drives the front wheel 7 to rotate to adjust the driving direction.

[0068] It has been proved in practice that the hoisting machine of the present application can perform longitudinal hoisting operations on 20-foot or 40-foot containers, and the operating capacity can reach 4-5 layers of high containers, breaking through the working restricted area of ​​ordinary front hoists and improving the utilization rate of the site. In addition, by increasing the lifting wire rope stroke of the hoist 9, the patent of the present invention can also be used for loading and unloading and handling of ship-borne containers at small barge docks.

[0069] The luffing boom is luffed to the lowest height by the luffing cylinder 24 to carry out container handling and driving operations. The minimum driving height of the equipment can be 9 meters (stacking 5-layer high containers), while the height of an ordinary gantry crane is the maximum stacking height of the container + the height of the spreader 9 + the height of the gantry main beam, which is about 19 meters (5 layers×2.9+2+2.5=19 meters). Since the center of gravity of the hoisting machine in this application is much lower than that of the gantry crane, a higher driving speed and better driving stability can be obtained.

[0070] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
