Detailed implementation manners

[0038] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings and specific implementation manners. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0039] As Figures 1 to 15 shown, the present invention proposes a large equipment in-plant transfer platform. The platform includes a loading platform 102, which carries large equipment 101 through the loading platform 102. Four groups of walking mechanisms 103 are arranged at both ends of the loading platform 102, and one group of steering and jacking mechanisms 105 is arranged below the loading platform 102, and four groups of side-shifting and jacking mechanisms 104 are arranged below the loading platform 102. An electrical control system 106 and a hydraulic system 107 are arranged on the upper part of the loading platform 102 at a position that does not affect the loading of the large equipment 101.

[0040] The load-bearing platform 102 is a steel structure, which is mainly welded by steel plates, steel sections, etc. Its upper load-bearing surface is used to support and position large equipment 101. The load-bearing platform 102 is strength-checked by finite element analysis to ensure that it can support large equipment 101. The load-bearing platform 102 adopts a sunken structure to reduce the center of gravity height of the large equipment 101 as much as possible after loading, so as to ensure that the transfer platform can carry large equipment 101 through low passages. A traction plate is arranged at each end of the load-bearing platform 102, and a plurality of traction holes are arranged on the traction plate. When the transfer platform is in a loaded or unloaded state, the corresponding traction hole can be selected according to the overall center of gravity position. When the transfer platform encounters unexpected working conditions such as power failure or failure, the connection between the reducer 302 and the wheel 301 can be released, and the transfer platform can be towed and moved by other measures.

[0041] There are 4 groups of walking mechanisms 103, each group includes a driving motor 303, a walking reducer 302, two wheel axles 306, a synchronous shaft 305, a coupling 307 and four wheels 301. Wheel axles 306 are respectively provided at both ends of the synchronous shaft, and two wheels 301 are respectively provided on each wheel axle 306; one side of the synchronous shaft is internally connected to the coupling 305, and the other side is externally connected to the walking reducer 302, and the walking reducer 302 is connected to the driving motor.

[0042] In some embodiments, the drive motor 303 uses a variable frequency brake motor to achieve the braking function of the smooth start and stop of the transfer platform. In order to reduce the number of shaking circles during emergency driving, the drive motor 303 uses a 6-pole motor. The tail shaft of the drive motor 303 can be installed with an emergency drive handwheel 304. When power failure or control system failure occurs, the motor brake can be manually released to drive the emergency drive handwheel 304 to drive the transfer platform in an emergency. The reducer 302 uses a combination of a parallel shaft helical gear reducer 302 and a worm gear reducer 302. The output torque of the reducer 302 considers sufficient margin to ensure that the transfer platform has sufficient walking power and the ability to pass ramps and obstacles. The output shaft of the reducer 302 is connected to the wheels 301 on both sides through a coupling 307 and a synchronous shaft 305 to achieve synchronous operation of the wheels 301 on both sides of the platform. Each set of walking mechanisms 103 is provided with 4 wheels 301, that is, the transfer platform is provided with a total of 16 wheels 301 to reduce the load of a single wheel 301 and reduce the pressure on the ground. All wheels 301 are powered wheels. When the ground is uneven and a wheel 301 cannot bear the load, the transfer platform can still move in a straight line normally. The wheels 301 are made of forged steel and the wheel cover is covered with a polyurethane tread of appropriate hardness to increase the friction between the wheels 301 and the ground and prevent damage to the ground during walking.

[0043] The steering and lifting mechanism 105 includes eight steering and lifting cylinders 401, a rotating platform 402, a steering motor 403, a steering speed reducer 404, a large gear ring 406, and a small gear 407. Eight groups of steering and lifting cylinders 401 are evenly arranged around the rotating platform 402. The rotating platform 402 is connected to the lower ends of the steering and lifting cylinders 401, and the upper ends of the steering and lifting cylinders 401 are connected to the load-bearing platform 102. A large gear ring 406 is provided inside the rotating platform 402. The large gear ring 406 meshes with the small gear 407. The small gear 407 is connected to the output shaft of the steering speed reducer 404, and the steering speed reducer 404 is connected to the steering motor 403.

[0044] In some embodiments, the rotating platform 402 is a ring structure, and the main body is a special large planar bearing. After the platform is lifted, the lower plane of the rotating platform 402 is supported on the ground, and the large gear ring 406 is installed on the inner circle of the rotating platform 402. The small gear 407 on the output shaft of the steering speed reducer 404 meshes with the large gear ring 406. When the small gear 407 drives the large gear ring 406 to rotate, the reversing of the transfer platform is completed. The steering motor 403 is a variable-frequency braking motor to achieve smooth start-stop and braking of the rotation. The steering motor 403 has a double-output shaft structure. In the case of power failure or malfunction, an emergency manual shaft 405 is temporarily installed for manual emergency operation. When the steering motor 403 operates, it can drive the transfer platform to rotate 360° in place.

[0045] There are four groups of side-shifting and lifting mechanisms 104, which are symmetrically arranged at the lower part of the load-bearing surface of the load-bearing platform 102. Each group of side-shifting and lifting mechanisms 104 consists of two sets of side-shifting and lifting cylinders 506, one lifting support 501, one set of side-shifting speed reducers 504, one set of side-shifting motors 505, two side-shifting wheels 502, and one side-shifting wheel shaft 503. One side-shifting and lifting cylinder 506 and one side-shifting wheel 502 are respectively provided on both sides of the lifting support. The upper end of the side-shifting and lifting cylinder 506 is fixedly connected to the load-bearing platform 102, and its lower end is fixedly connected to the lifting support 501. The side-shifting wheel shaft 503 is installed in the lifting support through a rolling bearing. Two side-shifting wheels 502 are installed on both sides of the lifting support. The output end of the side-shifting speed reducer 504 is directly connected to the side-shifting wheel shaft 503, and the side-shifting wheel shaft 503 drives the two side-shifting wheels 502 to rotate synchronously, that is, all the side-shifting wheels 502 can output walking power to avoid driving failure caused by uneven ground.

[0046] In some embodiments, the lateral movement wheel 502 adopts a steel core wheel 301 with the wheel surface coated with high-strength polyurethane to avoid damaging the on-site ground. The lateral movement wheel 502 adopts the smallest possible wheel diameter to meet the space limitation, while reducing the driving torque of the wheel 301 and the external dimension of the lateral movement reduction motor. The lateral movement motor 505 adopts an AC variable frequency motor and is synchronously driven by one frequency converter. The lateral movement motor 505 performs acceleration and deceleration control during start and stop to reduce the impact generated during lateral movement start and stop. The input end of the lateral movement speed reducer 504 has a two-way output shaft and can be installed with a detachable handwheel. In the case of power failure, fault and other working conditions, the handwheel can be manually driven synchronously to realize the emergency lateral movement of the transfer platform.

[0047] The hydraulic system 107 of the transfer platform includes a hydraulic oil tank 601, an oil pump 602, a pressure control valve 603, a steering and lifting direction control valve 604, a hydraulic lock 605, a lateral movement and lifting oil cylinder 606, and a lateral movement and lifting direction control valve 607. The hydraulic oil tank 601 is connected to the oil pump 602 and the pressure control valve 603. The hydraulic oil tank 601 is used to store the medium of the hydraulic system 107. The oil pump 602 provides power for the operation of the hydraulic system 107, and the pressure control valve 603 controls and regulates the pressure of the hydraulic system 107. The oil pump 602 is connected to the steering and lifting direction control valve 604 and the lateral movement and lifting direction control valve 608. The steering and lifting direction control valve 604 controls the action direction of the steering and lifting oil cylinder 401, and the lateral movement and lifting direction control valve 607 controls the action direction of the lateral movement and lifting oil cylinder 506. A hydraulic lock 605 and an 8-series synchronous motor 606 are respectively arranged between the oil pump 602 and the steering and lifting direction control valve 604 and the lateral movement and lifting direction control valve 608. The 8-series synchronous motor 606 ensures the synchronization of the actions of 8 sets of steering and lifting cylinders and 8 sets of lateral movement and lifting oil cylinders 506, avoiding tilting after lifting and mechanism jamming. The hydraulic system 107 is provided with a hydraulic lock 605, so that even in the case of power failure, the position of the oil cylinder after lifting can be effectively locked to ensure safety after lifting.

[0048] The main components of the electrical control system 106 of the transfer platform are assembled in the electrical control cabinet. The electrical control cabinet is equipped with a local operation panel and a remote controller, and the transfer platform can be operated locally or remotely. The local operation panel and the remote controller have uniqueness in control, that is, except for the emergency stop button, operations can only be performed on one of them to avoid operation instruction conflicts and increase safety risks. The operation mode is switched by the selection switch on the operation panel. The electrical control system 106 includes a PLC, a frequency converter, a contactor, a relay in the electrical cabinet, a travel switch, a proximity switch, a sensor on each actuator, and operation buttons on the local panel and the remote controller, etc.

[0049] The PLC is electrically connected to the frequency converter, contactor, and relay respectively. The frequency converter is electrically connected to the traveling motor 303 and the side-shifting motor 505; the contactor and relay are electrically connected to the hydraulic oil pump motor, steering motor 403, and hydraulic valve station; the hydraulic valve station is electrically connected to the side-shifting lifting cylinder 506 and the steering lifting cylinder 401. The PLC is also electrically connected to the travel switches, proximity switches, and sensors on each actuator. The PLC receives instructions from the cabinet buttons on the operation panel or the remote controller, controls the actions of each actuator according to the control program, and performs relevant safety interlocks and action interlocks for protection. The electrical control system 106 obtains power from the on-site distribution cabinet through explosion-proof plugs and cables.

[0050] Warning lights are installed at both ends of the transfer platform. During the walking process of the transfer platform, the warning lights continuously emit flashing warning lights to warn and remind the surrounding personnel to pay attention.

[0051] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
