Description

Technical Field

[0001] The present invention relates to the technical field of ship logistics equipment, and in particular to a climbing vehicle used for assisting in storing and accessing materials in a ship cabin. Background Art

[0002] The storage and retrieval of materials on shelves is a basic link in logistics. For land storage, automated stereoscopic warehouses are widely used as a solution for the storage and retrieval of large quantities of heavy materials, while small quantities of light materials are mostly stored and retrieved by manual handling. The height of the shelves in automated stereoscopic warehouses is usually more than 10 meters. When used with stackers and shuttles, materials can be automatically stored and retrieved according to the set program. Small quantities of light materials are stored on light shelves with a height of about 2 meters, which is within the ergonomic height range. Operators directly pick up and place materials on the shelves. If the materials on the high shelves are not convenient for humans to directly pick up and place, a manned high-level pickup truck is introduced to cooperate with the operation. This small equipment can move freely in the warehouse, and its platform can carry personnel and materials to be lifted and lowered. The storage and retrieval of materials is completed by combining manual handling with equipment lifting and horizontal transportation.

[0003] Compared with land, shipboard has smaller cabin space. Material storage and transportation equipment needs to maximize space utilization on the basis of adapting to the cabin size. On the other hand, affected by the swinging environment, ship equipment needs to consider stability and dynamic load. Existing equipment refers to land-based storage facilities to meet the needs of ship storage. Heavy materials are stored and retrieved by shelves and stackers, and light materials are stored on shelves and handled by manpower. At present, there is no high-level picking equipment that is suitable for ship occasions to solve the needs of high-level material storage and retrieval. The space utilization rate is limited, especially in the frozen compartment for storing food. The ambient temperature reaches -18°C, and the internal equipment needs to solve the problem of anti-skid and anti-freeze. In actual use, only low-height shelves are arranged in the freezer, and materials are handled by manpower. There is no auxiliary handling equipment that can be used in a frozen environment. Summary of the invention

[0004] The purpose of the present invention is to provide a climbing vehicle for storing and retrieving materials at high places on shelves in ship cabins, which can lift personnel and materials up and down, and move them in lanes. It can not only overcome the stability problem when the ship is swaying, but also meet the requirements for use in refrigerated cabins.

It is very convenient to install, adjust, and disassemble. Using a clamping and fixing method, the rail mounting seat and the corresponding rail pressure plate can move in the length direction of the ceiling rail and the floor rail, and have strong adaptability to the shelf. Even if the shelf column feet are unevenly arranged, the installation can be completed by adjusting the position of the rail mounting seat and the corresponding rail pressure plate. The adjustable support foot at the bottom of the floor rail transfers the vertical load to the cabin floor, and will not bring excessive additional load to the shelf.

[0016] The present invention uses gear rack forced drive combined with roller guide pairs to achieve walking, and uses chain closed-loop transmission combined with roller guidance to achieve lifting. There are sufficient constraints in all directions, which resolves the technical risk of equipment operation being out of position in the swaying environment of the ship. The gear rack transmission, chain transmission, and roller pair all have ice-breaking effects and are insensitive to the environment. The aerial platform can adapt well to freezing environments and solves the technical problem of assisting the storage and retrieval of materials in the ship's freezing compartment.

[0017] The present invention has a compact structure, light weight, and is easy to manufacture. It is suitable for material storage and transportation in a narrow space, and can adapt to shelves of different heights to a certain extent. It can serve as an important basis for further improving logistics storage and transportation efficiency and has significant economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 7 As shown, an aerial platform provided by an embodiment of the present invention comprises: a guide rail assembly 1, a aerial platform body 2, and a mobile power supply device 3. The guide rail assembly 1 is clamped and installed on the side of the shelf to facilitate assembly and disassembly. The aerial platform body 2 is installed on the guide rail assembly 1 and can walk along the lane to store and retrieve materials on the shelves on both sides of the lane. The mobile power supply device 3 is clamped and installed on the side of the shelf to provide power for the aerial platform body 2.

[0028] like Figure 2 As shown, the ground rail 11 of the guide rail assembly 1 is I-shaped, and multiple sections are spliced ​​by the ground rail joint 12. The ceiling rail 13 is I-shaped, with teeth on the bottom surface, and multiple sections are spliced ​​by the ceiling rail joint 14. The guide rail pressure plate 16 presses the ground rail 11 and the ceiling rail 13 onto the guide rail mounting seat 15. The guide rail mounting seat 15 is clamped on the column foot on the side of the shelf by the horseshoe clamp 17. The horseshoe clamp 17 is equipped with an adjusting bolt 18, which vertically supports the placement layer of the shelf. Rotating the adjusting bolt 18 can adjust the height of the ground rail 11 and the ceiling rail 13 accordingly. An adjustable support foot 19 is set below each guide rail mounting seat 15 of the ground rail 11 and each ground rail joint 12, which supports the cabin floor. Through the threaded adjustment method, it adapts to the distance from the cabin floor and transfers the load borne by the ground rail 11 to the cabin floor.

[0029] The guide rail assembly 1 is installed on the shelf, and has no independent installation interface with the cabin. All parts are installed by threaded fasteners, which is convenient for installation, disassembly and adjustment.

[0030] like Figure 3As shown, the main body 2 of the aerial platform is symmetrical in structure, wherein the traveling vehicle assembly 21 is a gantry structure, forming an unobstructed intermediate working area; the traveling drive assembly 22 and the lifting drive assembly 23 are installed at the top and bottom of the outer side of the gantry; the lifting chain assembly 24 and the lifting pulley assembly 25 are installed in the cavity of the column 2102 of the traveling vehicle assembly 21; the lifting platform assembly 26 has a vertical boss structure, which extends into the cavity through the through slot of the column 2102 and is fixedly connected to the lifting pulley assembly 25; the guardrail assembly 27 is hinged and can be opened and closed 90 degrees; the electrical assembly 28 is a combination of multiple small parts, which are distributed in the spare space of the overall layout.

The entire traveling vehicle assembly 21 slides along the ceiling rail 13 and the ground rail 11.

[0033] The output end of the travel drive assembly 22 is the gear 2201, which forms a gear rack transmission with the overhead rail 13 to drive the aerial platform body 2 to move in the lane. The meshing travel mode overcomes the influence of the ship's swaying. The roller guide and gear drive do not require high precision, are not sensitive to the environment, and are suitable for freezing environment conditions.

[0034] The lifting chain assembly 24 and the lifting pulley assembly 25 are integrally embedded in the two side columns 2102 of the traveling vehicle assembly 21, wherein the bearing seat 2401 and the sprocket 2402 are fixed at both ends of the column 2102. After the open-loop chain 2403 passes through the sprocket 2402, the two ends are connected to the pulley body 2501 to realize a closed loop. Composite rollers 2502 are installed around the pulley body 2501 to form a roller kinematic pair with the inner wall of the column 2102. The lifting drive assembly 23 drives the sprocket 2402 to rotate, driving the chain 2403 to pull the lifting pulley assembly 25 up or down.

[0035] The lifting execution part has no exposed parts and does not occupy external space. The roller guide and sprocket drive do not require high precision and are not sensitive to the environment, and can adapt to freezing environment conditions.

[0036] The lifting platform assembly 26 is the load-bearing part for people to stand and place materials in the present invention. Before the installation of the lifting platform assembly 26, the aerial platform vehicle body 2 is in a flat gantry state with a compact structure. The two sets of lifting platform assemblies 26 have a boss structure, which extends into the column 2102 and is fixed to the lifting pulley body 2501. They rise or fall independently under the drive of the two sets of lifting drive assemblies 23.

[0037] The guardrail of the guardrail assembly 27 is fixed to the lifting platform assembly 26 in a hinged manner, and rises or falls together. The guardrail body 2701 protects personnel and goods from falling off the platform. When closed, the strike lock 2702 is in a locked state. The strike lock 2702 can be vertically slid and unlocked by manual lifting, and then the guardrail body 2702 can be rotated and opened by hand.

[0038] The lines drawn from the travel drive assembly 22, the lifting drive assembly 23, and the collector 36 are all connected to the junction box 2801 of the electrical assembly 28; the button box 2802 is placed on the guardrail assembly 27, and the lines are also connected to the junction box 2801; the lifting travel switches 2803 are set at the top and bottom of the lifting direction, and the travel travel switches 2804 are set on both sides of the walking direction, and the lines are also all connected to the junction box. The button box 2802 is the control terminal of the present invention, which controls the operation in each direction.

[0039] The working principle of the present invention is: Figure 3 In the process, the operator opens the guardrail assembly 27 on one side, stands on the lifting platform assembly 26, closes the guardrail assembly 27, and operates Figure 7 The button box 2802 in the control unit controls the travel drive assembly 22 to be powered on or off. Figure 1 The main body 2 of the climbing vehicle moves or stops along the guide rail assembly 1. After reaching the storage and retrieval operation position, the button box 2802 is operated to control the lifting drive assembly 23 to be energized or de-energized, so that the lifting platform assemblies 26 on both sides can be raised or lowered or stopped. The side where the personnel stand is used as a personnel platform, and the other side is used as a cargo platform for placing materials. The materials are transferred between the shelf and the lifting platform assembly 26 by manpower. After the transfer is completed, the button box 2802 is operated again to control the lifting and walking movements. After reaching the lane entrance, the material transfer between the lane entrance and the shelf storage position is completed.
