Description

Technical Field

[0001] The present invention relates to the technical field of parking equipment, and in particular to a lifting and transverse moving parking equipment in which all parking spaces can be transversely moved and a variable frequency drive heavy load is provided. Background Art

[0002] Currently, most lifting and transverse moving equipment in the industry is fixed on the top floor and cannot be moved laterally, while other floors can be moved laterally. When a single entrance or exit is blocked by building columns or other immovable objects, the equipment space in that row must be sacrificed, and parking is not allowed in this row. This leads to problems such as uneven loading and a large number of non-standard designs. In addition, the maximum rated load of the vehicle loading platform of traditional lifting and transverse moving equipment in the industry is generally 2.35 tons, which is no longer suitable for the current era of high-load new energy vehicles.

[0003] The industry's lifting and traversing equipment generally has a maximum lifting speed of 6-7m / min, resulting in low efficiency for high-rise vehicle storage and retrieval. Furthermore, it utilizes a three-phase cage-type geared motor for direct drive without variable frequency speed regulation. This results in significant impact loads when the vehicle platform is raised and lowered, severely stressing the steel structure and causing loud impact noise. Currently, most of the industry's lifting and traversing equipment is traditional and lacks intelligent systems, making it difficult to meet modern digital requirements. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects and shortcomings of the prior art and to provide a fully transverse variable frequency driven heavy-load lifting and transverse parking equipment. Guide rails and transverse frames are installed on the top layer of the steel structure so that the top layer of the steel structure also has a transverse function, realizing that the top layer parking spaces can be moved transversely. It is equipped with an intelligent detection device and is fully automated without the need for personnel on duty, which helps to reduce the operating costs of the garage.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A fully transverse-type variable-frequency driven heavy-load lifting and transverse parking device comprises a steel structure, guide rails, a transverse frame, a lifting motor, a drum, a steel wire rope, and a vehicle loading plate. The guide rails are mounted on each crossbeam of the steel structure, the transverse frame is mounted on the guide rails, and the transverse frame can move transversely on the guide rails. The lifting motor and drum are mounted on the transverse frame. One end of the steel wire rope is fixed to the drum, and the other end is fixed to the vehicle loading plate. The lifting motor drives the drum to rotate forward and reverse, causing the steel wire rope to be wound in and out of the drum, thereby achieving the lifting and lowering of the vehicle loading plate.

[0007] PLC and frequency converter are used to jointly control the lifting motor, and a deceleration switch is set above the drum. The wire rope wound from the drum end moves laterally as the car loading plate is raised and lowered, triggering the deceleration switch. During the rising and falling process of the car loading plate, the rising and falling speeds of the car loading plate are controlled through the coordinated action of PLC, frequency converter and deceleration switch. The transverse frame drives the car loading plate to move laterally, realizing the lateral movement of all parking spaces on the steel structure.

[0008] Furthermore, the power of the lifting motor is greater than or equal to 4.0 kW, and the diameter of the reel is greater than or equal to 245 mm.

[0009] Furthermore, the rated load capacity of the vehicle loading plate is greater than or equal to 2.5t.

[0010] Furthermore, the parking equipment includes a vehicle length detector, a vehicle height detector and a vehicle width detector. The vehicle length detector uses two pairs of photoelectric sensors, which are respectively set at the four corners of the entrance and exit channels; the vehicle height detector uses a pair of photoelectric sensors, which are respectively set at the two opposite corners of the entrance and exit channels;

[0011] The vehicle width detector uses two pairs of photoelectric sensors, which are installed on both sides of the entrance and exit channels respectively; or the vehicle width detector uses two photoelectric sensors and two reflectors, with the photoelectric sensors installed in front of or behind the entrance and exit channels, and the reflectors installed in front of or behind the entrance and exit channels.

[0012] Furthermore, there are multi-layer parking spaces on both sides of the access channel formed by vehicle loading plates on the steel structure, and the multi-layer parking spaces on both sides are entered or exited through the access channel.

[0013] Furthermore, the parking device includes a vehicle detector, which directly uses a diffuse reflection photoelectric sensor. The diffuse reflection photoelectric sensor is arranged in the middle of the rear of the entrance and exit channel, and directly illuminates the rear of the vehicle through the diffuse reflection photoelectric sensor for sensing detection;

[0014] Alternatively, the vehicle detector uses an infrared photoelectric sensor and a reflector. The infrared photoelectric sensor is set in the middle of the rear of the entrance and exit channel, and the reflector is set in the middle of the rear of the vehicle loading plate of the entrance and exit channel. The infrared photoelectric sensor and the reflector cooperate to perform induction detection.

[0015] Furthermore, the parking equipment also includes a smart screen, which is installed in front of the entrance and exit passage. The smart screen is used for facial recognition and parking and retrieval operations.

[0016] Furthermore, the parking equipment also includes a camera, which is installed in the middle of the rear of the entrance and exit channel and is used for license plate recognition.

[0017] Furthermore, the PLC has a built-in automatic dispatching program for empty pallets, which can pre-dispatch empty pallets to the access channels for quick parking.

[0018] Furthermore, automatic doors are provided at the entrances and exits, and the number of entrances and exits is limited by increasing the number of automatic doors.

[0019] Compared with the existing technology, the present invention installs guide rails and transverse frames on the top floor of the steel structure, so that the top floor of the steel structure also has a transverse movement function, realizing the transverse movement of the top floor parking spaces, meeting more complex practical application needs of the equipment; by equipping the lifting motor with a frequency converter for variable frequency speed regulation, the reliability and stability of large-load equipment in high-speed operation are guaranteed; equipped with a full set of intelligent detection devices, fully automatic operation does not require personnel on duty, which helps to reduce garage operating costs.

DETAILED DESCRIPTION

[0031] The following is a further description of the full-transverse variable frequency drive heavy-load lifting and transverse parking equipment of the present invention in conjunction with the accompanying drawings and specific embodiments.

[0032] See also Figure 1 、 Figure 2 and Figure 3 The present invention discloses a fully transverse-type variable-frequency-driven heavy-load lifting and transverse parking system, comprising a steel structure 1, guide rails 2, a transverse frame 3, a lifting motor 4, a drum 5, a steel wire rope 6, and a vehicle loading plate 7. The guide rails 2 are mounted on each layer of crossbeams of the steel structure 1, namely, the bottom, middle, and top crossbeams 11 of the steel structure 1. The transverse frame 3 is mounted on the guide rails 2 and, driven by the transverse motor, can move transversely on each layer of the guide rails 2.

[0033] The lifting motor 4 and the drum 5 are installed on the transverse frame 3. One end of the wire rope 6 is fixed on the drum 5, and the other end is fixed on the vehicle loading plate 7. The lifting motor 4 drives the drum 5 to rotate forward and reverse, so that the wire rope 6 is wound in and out of the drum 5, thereby realizing the lifting and lowering of the vehicle loading plate 7. The transverse frame 3 drives the vehicle loading plate 7 to move horizontally, thereby realizing the horizontal movement of all parking spaces on the steel structure 1.

[0034] The present invention enables the top floor of the steel structure 1 to also have a transverse movement function, replacing the traditional top floor fixed parking space, and realizing the transverse movement of the top floor parking space. The rated load of the vehicle loading plate 7 is greater than or equal to 2.5t, which is applicable to most new energy vehicles on the market. The power of the lifting motor 4 of the present invention is greater than or equal to 4.0kW, and the diameter of the drum 5 is greater than or equal to 245mm. By increasing the power of the lifting motor 4 and the diameter of the drum 5, the lifting speed of the equipment reaches 8m / min. The frequency conversion drive is adopted to achieve a smooth increase and decrease in speed, with a small impact load, which is conducive to maintaining stable operation and reducing noise.

[0035] See also Figure 3 、 Figure 4 and Figure 5The present invention uses a programmable logic controller (PLC) 8 and a frequency converter (VFD) 9, both installed in the garage electrical cabinet, to jointly control the hoist motor 4. A deceleration switch 10 is located above the drum 5. The lateral movement of the wire rope 6, which is wound from the drum end, as the platform 7 is raised and lowered triggers the deceleration switch 10. The PLC 8, VFD 9, and deceleration switch 10 coordinate to regulate the speed of the platform 7's ascent and descent, both during initial ascent, nearing full ascent, and during initial descent and nearing full descent.

[0036] See also Figure 2 and Figure 5 If the traditional lifting and lateral movement operation mode is used, that is, direct lifting. During the rising process, due to the flexible characteristics of the wire rope 6, the carrier plate 7 will produce a fixed frequency of up and down vibration under the rated load; when it resonates with the steel structure 1, it will damage the equipment structure and shorten the equipment life. When the carrier plate 7 rises to its position, a large impact load will be generated, which may cause the carrier plate 7 to collide with the limit switch 11, thereby causing equipment failure. When it descends to its position, the same impact load will cause the carrier plate 7 to hit the ground track 12 at a higher speed of 8m / min, generating a lot of noise, and the impact load will damage the life of the ground track 12 and the carrier plate 7.

[0037] In order to ensure the reliability of deceleration and the safety of equipment operation, the present invention not only adds acceleration and deceleration programs in PLC8, but also equips a deceleration switch 10 when the carrier plate 7 is about to rise or fall into place, so as to realize reliable and controllable deceleration of the carrier plate 7.

[0038] See also Figure 6 The most direct and accurate method is to install the deceleration switch 10 on the ground between two parking spaces, determine the height of the deceleration switch 10 fixing bracket 13, and directly trigger the deceleration switch 10 by raising or lowering the vehicle loading platform 7. However, since the deceleration switch 10 needs to be installed in each parking space, the deceleration switch 10 will be hit when the vehicle loading platform 7 moves horizontally on the first floor, so this is not feasible.

[0039] See also Figure 7 The present invention cleverly places the deceleration switch 10 above the drum 5. The rotation of the drum 5 drives the wire rope 6 to wind around it, causing the wire rope 6 to produce a lateral displacement, which triggers the deceleration switch 10. The height of the vehicle loading plate 7 is determined according to the position of the wire rope 6 on the drum 5, thereby determining the position of the switch.

[0040] The hoisting motor 4 of the present invention drives the drum 5 in forward and reverse rotation, causing the wire rope 6 to wind in and out of the threaded groove of the drum 5, thereby raising and lowering the loading platform 7. Since the diameter of the drum 5 is fixed, the length of the wire rope 6 per turn around the drum 5 is fixed. Therefore, by counting the number of turns of the wire rope 6, the position of the loading platform 7, and thus the position of the deceleration switch 10, can be determined. Since the deceleration switch 10 is located above the drum 5 and does not interfere with any parking space, it does not affect the normal operation of the equipment.

[0041] See also Figure 8 The parking system also includes a vehicle length detector 14, a vehicle height detector 15, a vehicle width detector 16, and a vehicle detector 17. The vehicle length detector 14 uses two pairs of photoelectric sensors, one located at each of the four corners of the entrance and exit passages. These sensors detect vehicle length through opposing beams. The vehicle height detector 15 uses a pair of photoelectric sensors, one located at each of the two opposite corners of the entrance and exit passages. These sensors detect vehicle height through opposing beams.

[0042] Vehicle width detector 16 utilizes two pairs of photoelectric sensors and reflectors, one mounted on each side of the access passage. Alternatively, vehicle width detector 16 utilizes two photoelectric sensors and two reflectors, with the photoelectric sensors mounted in front of or behind the access passage, and the reflectors mounted in front of or behind the access passage. Photoelectric radiation strikes the reflectors, and the return radiation is received by the photoelectric sensors, detecting vehicle width. On either side of the access passage are multi-level parking spaces formed by vehicle loading plates 7 on the steel structure 1. Entry and exit through the access passage is performed on these multi-level parking spaces.

[0043] Vehicle detector 17 can be a diffuse reflection photoelectric sensor, located in the center of the rear of the access passage. Alternatively, it can be an infrared photoelectric sensor and a reflector, with the infrared sensor located in the center of the rear of the access passage and the reflector located in the center of the rear of the vehicle loading plate. When using a diffuse reflection photoelectric sensor, the vehicle detector 17 directly illuminates the rear of the vehicle for detection. When using an infrared photoelectric sensor and a reflector, the infrared photoelectric sensor and reflector work together for detection.

[0044] See also Figure 8 and Figure 9 The parking system also includes a smart screen 18 and a camera 19. Smart screen 18 is installed in front of the access lane, while camera 19 is installed in the center of the rear of the access lane. Smart screen 18 is used for facial recognition and parking and retrieval operations, while camera 19 is used for license plate recognition. PLC 8 has a built-in program for automatically dispatching empty pallets 7 to the access lane for quick parking. Automatic doors 20 are installed in front of the access lane to limit the number of entrances and exits.

[0045] This invention, predicated on the premise that all parking spaces are movable, features a comprehensive suite of intelligent features. To minimize costs, all detection devices are located at the entrances and exits, minimizing the number of photoelectric sensors used. Specifically, these include: beam photoelectric sensors installed at the entrances and exits to detect vehicle length, height, and width; diffuse reflection photoelectric sensors mounted on ground-mounted brackets for vehicle detection; a dedicated smart screen 18 for facial recognition; and a camera 19 for license plate recognition. The program design incorporates an automatic scheduling mechanism for unloaded vehicles.

[0046] Compared with traditional equipment (the entire train compartment can enter and exit), the present invention limits the number of entrances and exits by adding automatic doors 20. On the one hand, the vehicle length, width, height, and vehicle detection devices can all be concentrated in the entrance and exit channels, which significantly reduces the number of detection devices, reduces the failure rate and facilitates maintenance, thereby reducing costs and improving accuracy and safety; on the other hand, the appearance of the equipment can be fully enclosed, improving the overall aesthetics and adapting to various urban scenes.

[0047] Through these intelligent detection methods, the equipment can automatically and comprehensively determine whether a vehicle's length, width, and height meet parking specifications, eliminating the need for on-site personnel. Combined with license plate and facial recognition technology, it enables automated and rapid parking and retrieval. Furthermore, by combining vehicle detection with automatic scheduling of empty pallets, empty pallets can be pre-positioned to entry and exit parking spaces, enabling rapid parking. Fully automated operation requires no on-site personnel, helping to reduce garage operating costs.

[0048] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention should fall within the patent scope covered by the present invention.
