Abstract

This invention belongs to the field of workpiece transportation technology, specifically relating to a steering device, a lifting device, and a workpiece transfer method based on a track-mounted traveling mechanism. When the traveling mechanism carries a workpiece to a designated position on the track, the lifting device supports its weight, and the steering device drives the wheels to turn and reach the new track. Direct steering of the traveling mechanism is unnecessary, and the traveling mechanism moves using a winch. This facilitates quick switching of power input and adjustment of the traveling mechanism's direction after changing tracks. This invention effectively improves the stability of traveling and turning when transporting large workpieces on tracks, eliminating the need for a separate traveling mechanism steering system; only wheel steering is required, thus improving workpiece transportation safety.

Description

Technical Field

[0001] This invention belongs to the field of workpiece transportation technology, specifically relating to a turning device for a track-based walking mechanism, a lifting device, and a workpiece transfer method based on a track-based walking mechanism. Background Technology

[0002] Currently, the transportation of some large workpieces (large volume, complex structure or hollow profile, such as the main body of marine photovoltaic trusses) usually adopts a traveling mechanism set on a fixed track for transportation and transfer. However, when turning, an arc track is usually required to achieve the turning. If the volume and mass of the component structure are large, there is a risk of tipping over under the action of turning inertia. In addition, due to the imbalance of forces, the transported component is prone to excessive local deformation due to excessive force, which affects the quality of the component and the safety of transportation. Summary of the Invention

[0003] This invention addresses the problems encountered when transporting large workpieces, such as the need for turning, the risk of tipping over due to the inertia of the large volume and mass of the components, and the potential for deformation due to excessive local stress caused by unbalanced forces, which affects the quality and safety of the transport. The invention provides a turning device for a track-based traveling mechanism, a lifting device, and a workpiece transfer method based on the track-based traveling mechanism. By setting a turning device at the intersection of the tracks, the traveling mechanism can directly drive the short track corresponding to the wheel position to turn synchronously when it stops, thus achieving smooth turning of the traveling mechanism during transport and eliminating the risk of tipping over.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A turning device for a track-based walking mechanism is positioned at the intersection of two tracks. Each track is equipped with a limit buffer for limiting and stopping the walking mechanism on the track. The device includes a short track, a support member, and a rotating member. The short track is adapted to each of the two tracks by rotation. A turning platform is fixedly mounted on the lower side of the short track. The support member is rotatably sleeved on the outer side of the turning platform. Both ends of the short track are slidably mounted on the upper side of the support member. The rotating member is coupled below the turning platform. The rotating member drives the turning platform to rotate, causing the short track and its wheels to rotate until the short track aligns with the next track, thus achieving turning.

[0006] Preferably, the support member is fixedly installed on the ground foundation.

[0007] Preferably, the steering platform and the support are rotatably connected via a slewing bearing.

[0008] A lifting device, comprising multiple components, is used for lifting workpieces. It includes a support frame, a lifting mechanism, and a lifting platform arranged sequentially from bottom to top. The upper side of the lifting platform matches the outer side of the workpiece. The lifting mechanism is used to drive the lifting platform to rise and fall. The support frame is used to support and limit the lifting mechanism. The lifting mechanism drives the lifting platform to rise and fall, thereby causing the workpiece on it to rise and fall.

[0009] Preferably, the support frame includes a lower pad and a plurality of circumferentially evenly distributed support rods fixedly disposed on the upper side of the pad, with the upper ends of the plurality of support rods fixedly connected to the outside of the lifting mechanism.

[0010] A workpiece transfer method based on a track-walking mechanism is used for track transport of workpieces. The workpiece is placed on a walking mechanism above the track, and the track-walking mechanism is equipped with a steering device at each intersection of the tracks. When the walking mechanism is stopped by a limit buffer, and the wheels are all on the corresponding short tracks, the walking mechanism and the workpiece on it are lifted by multiple lifting devices. At this time, the workpiece and the walking mechanism are supported by multiple lifting devices and the wheels are still on the corresponding short tracks.

[0011] Then, the rotating component drives the short track to rotate in the same direction as the extension of another track. The wheels rotate synchronously with the corresponding short track and turn. The lifting mechanism drives the lifting platform to fall, separating it from the traveling mechanism and the workpiece. The traveling mechanism then travels along the short track after the turn to the new track after the turn.

[0012] Preferably, each track includes a parallel track structure. A winch and a fixed pulley are fixedly installed on the ground foundation at both ends of the track. A wire rope is installed on the winch. The wire rope is wound around the winch in the middle and its two ends are respectively connected to the opposite sides of the traveling mechanism. One end of the wire rope is wound around the fixed pulley. The traveling mechanism is driven by rotating the winch to wind up or release the wire rope.

[0013] Preferably, each side of the walking mechanism is provided with a hanging ring, and both ends of the wire rope are connected to the hanging ring on the walking mechanism through hooks. The hanging ring and hook cooperate to facilitate quick connection or disconnection of the wire rope from the walking mechanism.

[0014] Preferably, after the walking mechanism completes the turn, it removes the wire rope corresponding to the previous track, connects the wire rope corresponding to the track in the next walking direction, and drives the walking mechanism to walk along another track through another winch.

[0015] The beneficial effects of the present invention through the above technical solution are as follows:

[0016] 1. This invention achieves walking guidance through the cooperation of a track and a walking mechanism, and achieves traction walking through the cooperation of a winch, a fixed pulley and a wire rope. In this way, the direction of traction force is consistent with the direction of travel, and because the wheels of the walking mechanism rotate in all directions, it is easy to ensure the stability of the walking process and avoid safety hazards.

[0017] 2. This invention directly drives the short track and its wheels to rotate through a rotating component, thereby achieving steering of the walking mechanism. This makes the walking and steering of the large walking mechanism smooth, effectively avoiding the offset and overturning forces when the walking mechanism directly turns. It ensures that the walking mechanism can only travel in a straight line during the walking process, improving the stability and safety of workpiece transfer, and avoiding local deformation caused by local forces such as centrifugal force on the workpiece during turning.

[0018] 3. The present invention supports the traveling mechanism that has stopped before the steering is to be turned by using a lifting device, thereby ensuring the stability of the rotating parts in the steering device when rotating on the short track and wheels, reducing power input, and improving the stability and safety of large workpiece transportation.

[0024] 100 represents the workpiece, and 200 represents the limit buffer. Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1-4As shown, this embodiment provides a turning device for a track walking mechanism, which is set at the intersection of two tracks 1. Each track 1 is equipped with a limit buffer 200 for limiting and stopping the walking mechanism 2 on the track. The limit buffer 200 can be a fixed block fixed to the ground foundation, with an elastic element (rubber or damper, etc.) on the front side to stop and buffer the walking mechanism 2, ensuring that it stops at the designated position. The walking mechanism 2 can be a frame trolley mechanism, that is, the upper side is a support frame or support plate, and the lower side is equipped with casters. The walking mechanism 2 moves by front and rear traction power.

[0027] A turning device for a track-mounted traveling mechanism includes a short track 3, a support member 4, and a rotating member 5. The short track 3 is adapted to two tracks 1 by rotation; that is, at the intersection of the tracks, a section of one of the two tracks 1 is cut off, leaving only one section as the short track 3, and the short track 3 matches the cut portion of the two tracks 1. A turning platform 6 is fixedly installed on the lower side of the short track 3. When the turning platform 6 rotates, the short track 3 rotates synchronously to adjust the short track 3 to correspond with the two tracks 1. The support member 4 is rotatably sleeved on the outer side of the turning platform 6. The support member 4 is fixedly installed on the ground foundation. Both ends of the short track 3 are slidably installed on the upper side of the support member 4. By setting the support member 4, when the walking mechanism 2 reaches above the short track 3, its gravity is prevented from acting directly on the steering platform 6. Instead, the support member 4 supports and bears the main pressure. The support member 4 is a ring structure. A rotating member 5 is coupled below the steering platform 6. The rotating member 5 is used to drive the steering platform 6 to rotate. The rotating member 5 is a motor. Specifically, a groove is opened in the ground foundation, and the motor is fixedly installed in the groove. Its output end is fixedly connected to the steering platform 6.

[0028] The steering platform 6 and the support member 4 are rotatably connected by a slewing bearing 7, which ensures smooth rotation of the steering platform 6 and reduces the power input of the motor.

[0029] A lifting device, comprising multiple components, is used for lifting a workpiece 100. It includes a support frame 8, a lifting mechanism 9, and a lifting platform 10 arranged sequentially from bottom to top. The upper side of the lifting platform 10 matches the outer side of the workpiece 100, ensuring a larger and more uniform force-bearing surface when supporting the workpiece 100. The lifting mechanism 9 is used to drive the lifting platform 10 to rise and fall. The lifting mechanism 9 is a hydraulic jack. The support frame 8 supports and limits the lifting mechanism 9. The support frame 8 includes a lower pad and multiple circumferentially evenly distributed support rods fixedly mounted on the upper side of the pad. The upper ends of the support rods are fixedly connected to the outer side of the lifting mechanism 9. The pad increases the ground foundation's load-bearing area and improves the equipment's load-bearing capacity when supporting the workpiece 100. The support rods ensure the structural strength of the device and prevent the lifting mechanism 9 from tilting or tipping over.

[0030] A workpiece transfer method based on a track-walking mechanism is provided for track transport of workpiece 100. The workpiece 100 is placed on a walking mechanism 2 above the track, and the track-walking mechanism steering device is provided at each intersection of the track 1. When the walking mechanism 2 is stopped by a limit buffer 200, the wheels 11 are all located on the corresponding short track 3. Furthermore, it is ensured that the wheels are located in the middle of the short track 3, corresponding vertically to the rotation center of the steering platform 6. Furthermore, the wheels 11 are installed by self-aligning roller bearings to meet certain error requirements.

[0031] The traveling mechanism 2 and the workpiece 100 on it are lifted by multiple lifting devices as described above. At this time, the workpiece 100 and the traveling mechanism 2 are supported by multiple lifting devices and the wheels 11 are still located on the corresponding short track 3. Furthermore, the lifting devices are set at positions where the traveling mechanism 2 and the workpiece 100 have relatively high strength (such as the intersection of rods). Multiple lifting devices ensure that the workpiece 100 and the traveling mechanism 2 rise and fall synchronously at various points. Furthermore, the function of the lifting devices is to replace the steering device to bear the weight of the traveling mechanism 2 and the workpiece 100 on it, without having to raise the traveling mechanism 2 or even deviate from the track 1.

[0032] Subsequently, the short track 3 is driven to rotate by the rotating component 5 to be consistent with the extension direction of the other track 1. The wheel 11 rotates synchronously with the corresponding short track 3 and turns. The lifting mechanism 9 drives the lifting platform 10 to fall and separate from the walking mechanism 2 and the workpiece 100. The walking mechanism 2 travels along the short track 3 after turning to the new track 1 after turning. Therefore, the walking mechanism 2 does not need to turn as a whole. Only the wheel 11 needs to turn to meet the turning and walking needs, which effectively ensures smooth turning.

[0033] Each track 1 includes parallel track structures. A winch 12 and a fixed pulley 13 are fixedly mounted on the ground at both ends of each track 1. A wire rope 14 is mounted on the winch 12. The wire rope 14 is wound around the winch 12 in the middle, and its two ends are connected to opposite sides of the traveling mechanism 2. One end of the wire rope 14 passes through the fixed pulley 13. Each side of the traveling mechanism 2 has a hanging ring. Both ends of the wire rope 14 are connected to the hanging rings on the traveling mechanism 2 via hooks. After mechanism 2 completes the turn, the wire rope 14 corresponding to the previous track 1 is removed, and the wire rope 14 corresponding to the track 1 in the next travel direction is connected. The winch 12 drives the winding of one end of the wire rope 14 while releasing the other end of the wire rope 14, thereby enabling the traveling mechanism 2 to travel along track 1. The forward and backward movement of the traveling mechanism 2 can be achieved by reversing the winch 12. With the rotation of the lower wheel 11 of the traveling mechanism 2, the power can be quickly switched after the traveling mechanism 2 turns. Only the hook at the end of the corresponding wire rope 14 needs to be replaced.

[0034] Using the workpiece transfer method of the present invention, after reaching the designated position of the track 1, the workpiece 100 and the traveling mechanism 2 are supported by the lifting device, the wheel 11 is turned by the steering device and the track 1 is changed at the same time, and the workpiece 100 can be transferred by the traveling mechanism 2 by changing the hook at the end of the wire rope 14, so as to achieve rapid and stable turning and power adjustment, which greatly improves the safety of transferring large workpieces and reduces the possibility of damage to the workpiece 100 during the transfer process.

[0035] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present invention should be included within the scope of the present invention.
