[0051] As Figures 1 to 3 As shown, the embodiments of the present application provide a stabbing device for assembling crane outriggers, including: a transfer trolley 1, a driving mechanism 2, a lifting mechanism 3, and a stabbing mechanism 5. Among them, the transfer trolleys 1 are arranged on opposite sides of the crane. The driving mechanisms 2 are respectively arranged at the bottom of the transfer trolleys 1 and can drive the transfer trolleys 1 to move along a preset track to the position of the outriggers of the opposite crane. The lifting mechanism 3 is arranged inside the transfer trolley 1 and can perform lifting operation or lowering operation inside the transfer trolley 1. The stabbing mechanism 5 is arranged on the lifting mechanism 3 to move synchronously with the lifting mechanism 3 and stab the outrigger into the crane in the horizontal stabbing direction at a specified stabbing height. The specific structures of each component will be specifically described below.

[0052] In this embodiment, the transfer trolley 1 includes a base and a main body housing. Among them, the base and the main body housing are in communication with each other. Specifically, the wall body of the base and the wall body of the main body housing are integrally formed. The base has a height and its interior is a hollow structure. A support bracket 11 is provided in the hollow structure, and the support bracket 11 is connected to the inner wall of the base. The support bracket 11 can reduce the use of materials and the weight of the base. The main body housing has a certain height, and its interior is set as a hollow structure for accommodating the lifting mechanism 3 and the poking and loading mechanism 5. In addition, an opening is provided on one side of the main body housing. This side of the main body housing faces the crane, and this opening is used for the poking and loading mechanism 5 to operate in the horizontal poking and loading direction. In one example, the main body housing is located in the middle of the base, so that the overall transfer trolley 1 has a "mountain" - shaped structure. The two side ends of the base relative to the main body housing are respectively called the moving side end face and the second side end face.

[0053] In this embodiment, to facilitate the installation of the crane legs, the crane legs are distributed on both sides of the crane. Correspondingly, the transfer trolley 1 is arranged on the opposite sides of the crane so as to simultaneously poke and install the crane legs.

[0054] The driving mechanism 2 is respectively arranged at the bottom of the transfer trolley 1, and can drive the transfer trolley 1 to move to a position relative to the legs of the crane along a preset track, wherein the preset track is relatively arranged on both sides of the crane. In this embodiment, the driving mechanism 2 includes a driving motor 21, a first rotating shaft 23 bearing 22, a first rotating shaft 23, a driving wheel 24, a conveyor belt, a second rotating shaft 27 bearing 26, a second rotating shaft 27 and a driven wheel 28. Among them, the driving motor 21 is arranged outside the bottom of the transfer trolley 1, specifically, the driving motor 21 is arranged on the upper part of the base of the transfer trolley 1 and is located on the first side platform. The first rotating shaft 23 bearing 22 is arranged at the opposite ends of the first end of the bottom of the transfer trolley 1 along the horizontal poking direction, wherein the first end and the second end of the bottom of the transfer trolley 1 are the opposite ends of the transfer trolley 1 in the driving direction, and the horizontal poking direction refers to the poking operation direction of the poking mechanism 5 relative to the crane. Further, corresponding to the internal structure of the base, a supporting bracket 11 is provided, and the overall shape of the supporting bracket 11 corresponds to the shape of the base, and both are square. The first rotating shaft 23 and the bearing 22 are arranged at opposite ends of the first end of the support bracket 11 along the horizontal poking direction. The first rotating shaft 23 is connected between the first rotating shaft 23 and the bearing 22, and a transmission wheel 25 is arranged on the first rotating shaft 23. The driving wheel 24 is respectively arranged at the two ends of the first rotating shaft 23. The conveyor belt is wound around the output end of the driving motor 21 and the transmission wheel 25, so that the output end of the driving motor 21 drives the first rotating shaft 23 to rotate through the conveyor belt and the transmission wheel 25, and the first rotating shaft 23 drives the driving wheel 24 to rotate. The second rotating shaft 27 and the bearing 26 are arranged at opposite ends of the second end of the bottom of the transfer trolley 1 along the horizontal poking direction, specifically, the second rotating shaft 27 and the bearing 26 are arranged at opposite ends of the second end of the support bracket 11 along the horizontal poking direction. The second rotating shaft 27 is connected between the second rotating shaft 27 and the bearing 26. The driven wheels 28 are respectively arranged at the two ends of the second rotating shaft 27. The driven wheel 28 rotates under the drive of the driving wheel 24, and then can drive the transfer trolley 1 to move.

[0055] In this embodiment, the lifting mechanism 3 is disposed inside the transfer trolley 1 and can perform lifting or lowering operations inside the transfer trolley 1. Specifically, the lifting mechanism 3 includes: a support plate 31, a scissor structure 32, a driving oil cylinder 33, and a lifting platform 34. Among them, the support plate 31 is disposed at the bottom of the transfer trolley 1, specifically on the support bracket 11. The support plate 31 is in the shape of a flat plate and has a shape adapted to the support bracket 11. The scissor structure 32 is disposed on the support plate 31. One end of the driving oil cylinder 33 is fixed on the support plate 31, and the other end is connected to the scissor structure 32 to drive the scissor structure 32. When the other end of the driving oil cylinder 33 extends, the scissor structure 32 lifts; when the other end of the driving oil cylinder 33 retracts, the scissor structure 32 descends. The driving oil cylinder 33 is connected to a hydraulic control device 54 (described below), and the hydraulic control device 54 controls the operation of the driving oil cylinder 33. The lifting platform 34 is connected to the scissor structure 32 to perform lifting or lowering operations under the drive of the scissor structure 32. The lifting platform 34 is used to carry the barrel poking mechanism 5.

[0056] In one example, in order to meet the lifting height of the barrel poking mechanism 5, a height increasing platform 35 is further provided on the lifting platform 34, and the height increasing platform 35 is used when the lifting height of the lifting mechanism 3 does not meet the lifting requirements of the barrel poking mechanism 5. Specifically, in one example, the height increasing platform 35 can have a fixed height and can be set to multiple, and the height of each height increasing platform 35 is different, so as to meet different height increasing requirements. In one example, the height increasing platform 35 includes a height increasing plate, an adjustable bolt structure, and a foldable connecting rod. One end of the foldable connecting rod is fixed on the lifting platform 34, and the other end of the foldable connecting rod is fixed to the height increasing plate. The foldable connecting rod cooperates with the adjustable bolt structure in the supporting state to support and raise the height increasing plate; the foldable connecting rod cooperates with the adjustable bolt structure in the folded state to lower the height increasing plate. The adjustable bolt structure includes a bolt column and a screw rod. One end of the bolt column is fixed on the lifting platform 34, and the other end of the bolt column is provided with an external thread structure; one end of the screw rod is fixedly connected to the height increasing plate, and the inner wall of the other end of the screw rod is provided with an internal thread structure, and the internal thread structure is screwed with the external thread structure at the other end of the bolt column. By adjusting the screwing degree of the internal thread structure and the external thread structure, the distance between the screw rod and the bolt column is changed, so as to change the height of the height increasing plate.

[0057] In this embodiment, in order to ensure the stable operation of the lifting mechanism 3 in the transfer trolley 1, a guiding component is further included. The guiding component is disposed between the vertical inner wall of the transfer trolley 1 and the lifting mechanism 3 and is used to guide the lifting mechanism 3 to move vertically inside the transfer trolley 1.

[0058] Specifically, in this embodiment, the guiding assembly includes a first support disc frame 41, a second support disc frame 42, guiding wheels, and a guiding track. Among them, the first support disc frame 41 is arranged on the support plate 31 and is located on both sides of the scissor structure 32, that is, there are two first support disc frames 41, which are respectively arranged on the support plate 31 and located on both sides of the scissor structure 32. In an example, the first support disc frame 41 is L-shaped, and the horizontal end side of the L-shaped first support disc frame 41 is fixed to the support plate 31 by bolts, and the vertical end side of the L-shaped first support disc frame 41 is arranged parallel to the vertical inner wall of the transfer trolley 1. The second support disc frame 42 is arranged on the lifting platform 34 and is located on both sides of the stabbing and loading mechanism 5, that is, there are two second support disc frames 42, which are respectively arranged on the lifting platform 34 and located on both sides of the stabbing and loading mechanism 5. In an example, the second support disc frame 42 is L-shaped, and the horizontal end side of the L-shaped second support disc frame 42 is fixed to the lifting platform 34 by bolts, and the vertical end side of the L-shaped second support disc frame 42 is arranged parallel to the vertical inner wall of the transfer trolley 1. The first support disc frame 41 and the second support disc frame 42 have the same structure, and in the vertical direction, the first support disc frame 41 and the second support disc frame 42 are arranged on the same straight line.

[0059] The guiding wheels are respectively arranged on the first support disc frame 41 and the first support disc frame 41, and the axial direction of the guiding wheels is perpendicular to the vertical inner wall of the transfer trolley 1. Specifically, the guiding wheels include a first guiding wheel 43 and a second guiding wheel 44. Among them, the first guiding wheel 43 is arranged on the first support disc frame 41 through a first guiding shaft, the axial direction of the first guiding shaft is perpendicular to the vertical inner wall of the transfer trolley 1, and the circumferential end face of the first guiding wheel 43 is perpendicular to the axial direction of the first guiding shaft. The number of the first guiding wheels 43 arranged on the first support disc frame 41 is four, and in the vertical direction, every two first guiding wheels 43 are arranged on the same straight line. The second guiding wheel 44 is arranged on the second support disc frame 42 through a second guiding shaft, the axial direction of the second guiding shaft is perpendicular to the vertical inner wall of the transfer trolley 1, and the circumferential end face of the second guiding wheel 44 is perpendicular to the axial direction of the second guiding shaft. The number of the second guiding wheels 44 arranged on the second support disc frame 42 is four, and in the vertical direction, every two second guiding wheels 44 are arranged on the same straight line. In this embodiment, in the vertical direction, the first guiding wheel 43 and the second guiding wheel 44 are arranged on the same straight line.

[0060] The guiding track is arranged on the vertical inner wall of the transfer trolley 1 relative to the guiding wheel in the vertical direction, and the guiding wheel moves along the guiding track. In one example, the guiding track is provided in two, namely, including a first guiding track and a second guiding track. The first guiding track and the second guiding track are respectively distributed on two vertical straight lines and are parallel. The first guiding track contacts the circumferential end face of the first guiding wheel 43 distributed on the same straight line, and is used to limit the movement of the first guiding wheel 43 in the vertical direction. The second guiding track contacts the circumferential end face of the second guiding wheel 44 distributed on the same straight line, and is used to limit the movement of the second guiding wheel 44 in the vertical direction. In one example, the guiding track is integrally stamped with the vertical inner wall of the transfer trolley 1, or it can also be a separate guiding track fixed to the vertical inner wall of the transfer trolley 1 by bolts.

[0061] The lifting mechanism 3 moves stably in the transfer trolley 1 through the guiding assembly, so as to drive the stabbing mechanism 5 to move synchronously, and when reaching the specified stabbing height, the stabbing mechanism 5 stabs the outrigger into the crane along the horizontal stabbing direction. In this embodiment, the stabbing mechanism 5 includes a positioning member 51, a multi-stage hydraulic cylinder 52, a stabbing member 53 and a hydraulic control device 54. Among them, the positioning member 51 is arranged on the lifting platform 34. In one example, based on the fact that there is a raised platform 35 on the lifting platform 34, the positioning member 51 is arranged on the raised platform 35. In one example, the positioning member 51 is provided in two. The positioning member 51 includes an integrally formed fixed seat and a connecting platform. Among them, one connecting platform is provided with a mounting hole adapted to the multi-stage hydraulic cylinder 52, and the other connecting platform is provided with a mounting groove adapted to the multi-stage hydraulic cylinder 52. The end of the multi-stage hydraulic cylinder 52 is installed in the mounting groove of the connecting platform, and the other end of the multi-stage hydraulic cylinder 52 is sleeved in the mounting hole of the connecting platform, so as to install the multi-stage hydraulic cylinder 52 on the connecting platform. Of course, in other examples, mounting holes are respectively provided on the two connecting platforms, and the multi-stage hydraulic cylinder 52 is respectively sleeved in the two mounting holes, so as to install the multi-stage hydraulic cylinder 52 on the connecting platform. The multi-stage hydraulic cylinder 52 is connected to the positioning member 51 along the horizontal stabbing direction. The multi-stage hydraulic cylinder 52 includes at least two stages, and the extending length of each stage is different. The stabbing member 53 is arranged at the output end of the multi-stage hydraulic cylinder 52 along the horizontal stabbing direction. The stabbing member 53 has a structure that can be positioned and connected to the outrigger. In one embodiment, the end face of the stabbing member 53 facing the crane side is set to be circular and flat. The end face of the circular and flat stabbing member 53 can increase the contact area with the outrigger, thereby improving the stability of the docking. Among them, the horizontal stabbing direction is the direction of the transfer trolley 1 relative to the crane. The hydraulic control device 54 is arranged outside the transfer trolley 1. Specifically, the hydraulic control device 54 on the second side end face of the transfer trolley 1 is connected to the multi-stage hydraulic cylinder 52 to control the operation of the multi-stage hydraulic cylinder 52.

[0062] In this embodiment, considering that there may be deviations during the assembly of the outriggers, in order to correct the installation deviation of the outriggers in a timely manner, the stabbing and installing mechanism 5 further includes a hook 55. The hook 55 is detachably connected to the stabbing and installing member 53 and can be suspended from the outrigger to adjust the position of the outrigger. In one example, the hook 55 is connected to the outrigger through a hanging rope to adjust the position of the outrigger.

[0063] In this embodiment, in order to enable the lifting mechanism 3 to lift to the specified assembly height and enable the stabbing and installing mechanism 5 to stab the outrigger into the crane along the horizontal stabbing direction, a visual sensing device (not shown) is further provided. The visual sensing device is disposed on the transfer trolley 1 relative to the stabbing and installing member 53 and is used to obtain the position information of the outrigger. Among them, the visual sensing device includes a microprocessor of a camera. The camera is used to obtain an image of the outrigger and transmit the image to the microprocessor. The microprocessor processes the image to obtain the position information of the outrigger, and then transmits the position information of the outrigger to the lifting mechanism 3 and the stabbing and installing mechanism 5, so as to control the lifting mechanism 3 to lift to the specified assembly height and control the stabbing and installing mechanism 5 to extend the corresponding stabbing length along the horizontal stabbing direction to stab the outrigger into the crane. Of course, in other examples, the visual sensing device includes a lidar sensor.

[0064] Of course, in other instances, the lifting height of the lifting mechanism 3 can also be controlled manually. Similarly, the extending length of the stabbing and installing mechanism 5 can also be controlled manually to achieve the stabbing of the outrigger.

[0065] In this embodiment, based on the fact that the lifting mechanism 3, the stabbing and installing mechanism 5, and the driving mechanism 2 all operate through electricity, in order to be able to supply continuous and workable electrical energy to these mechanisms, a power supply device 6 is further provided. The power supply device 6 is disposed at the bottom of the transfer trolley 1 and is used to obtain external electrical energy. In one example, the power supply device 6 includes a power connection terminal and a power supply line. The power connection terminal is disposed at the bottom of the transfer trolley 1 and is used to obtain external electrical energy; the power supply line is connected between the power connection terminal and the lifting mechanism 3, the stabbing and installing mechanism 5, and the driving mechanism 2 to transmit the external electrical energy obtained by the power connection terminal to the lifting mechanism 3, the stabbing and installing mechanism 5, and the driving mechanism 2.

[0066] Furthermore, in this embodiment, considering that the actual operating conditions of the lifting mechanism 3, the stabbing and installing mechanism 5, and the driving mechanism 2 are different and their power consumptions are also different, in order to reasonably distribute the power of the power supply device 6, an electronic control device 7 is further included. The electronic control device 7 is disposed on the side of the driving mechanism 2, specifically on the side of the driving motor 21. The electronic control device 7 is respectively connected to the power supply device 6, the lifting mechanism 3, the stabbing and installing mechanism 5, and the driving mechanism 2, and is used to obtain the electrical energy provided by the power supply device 6 and distribute the obtained electrical energy to the lifting mechanism 3, the stabbing and installing mechanism 5, and the driving mechanism 2.
