Description

Technical Field

[0001] The invention relates to the technical field of logistics, and in particular to a vehicle-carrying hoist cargo platform and a vehicle-carrying hoist. Background Art

[0002] With the increasing development of warehousing and logistics, more and more manufacturers are adopting dense layered storage of goods in automated warehouses. In order to save space in the compact space of automated warehouses and reduce logistics costs under tight budgets, a car lift can be installed at the end of the shelf in the automated warehouse to realize the transfer and change of shuttles between different layers of the shelves, reduce the matching number of shuttle equipment, reduce the failure rate, and better improve the shuttle's layer change efficiency without affecting the system throughput, meeting the overall performance requirements of the system.

[0003] The existing car lifts are mainly in the form of a four-column structure. First, the cargo platform uses four columns as guide rails for vertical lifting. This working condition has very high requirements on the parallelism of the metal structure, the vertical height of the columns and the installation accuracy of the entire car lift. During the lifting operation, the guide wheel group of the car platform is prone to uneven force and is very easy to wear. In addition, the working plane accuracy of the car platform cannot be guaranteed, which affects the horizontal connection between the cargo platform and the shelf track.

[0004] Secondly, the four-column metal structure determines that the cargo platform needs a four-sided frame in conjunction with the four columns for guide rails and guide wheels, which not only makes the appearance bulky, but also increases the structural complexity and weight of the cargo platform.

[0005] At the same time, the cargo platform of the existing car hoist adopts a double-layer profile frame structure, whose profile frame is fixed and the track gauge is also fixed, resulting in the corresponding fixed track spacing. When the shuttle car on the car hoist has a slight change in its external dimensions or track gauge, it cannot be flexibly used; and the fixed profile frame structure makes it difficult for the cargo platform to dock with the shelf track due to the existence of installation and processing accuracy errors. There is often a certain gap when docking, which brings inconvenience to precise positioning and is not conducive to the smooth operation of the shuttle car between the car hoist and the shelf track; of course, the double-layer profile frame structure also makes the vertical height of the cargo platform higher, resulting in the lowest level conveyor line and its shelf layer height docking with it are higher, reducing the effective utilization space of the dense warehouse.

[0006] Based on this, the present invention provides a vehicle loading platform and a vehicle loading platform to solve the above-mentioned technical problems. Summary of the invention

[0007] The purpose of the present invention is to provide a car loading platform to solve the technical problems that the existing double-column car loading platform has low flexibility and cannot be accurately docked with the shelf rail.

[0008] The present invention also aims to provide a car hoist for solving the above-mentioned technical problems.

[0009] Based on the above first object, the present invention provides a vehicle loading platform of a vehicle loading hoist, comprising a loading platform frame;

[0010] The cargo platform frame includes a pair of U-shaped plates, a transverse beam and a mounting seat, and a plurality of guide wheel groups are arranged on the inner side of the horizontal connecting portion and the vertical portion of the back of the U-shaped plate; the two U-shaped plates are respectively used to be clamped on two columns, and the guide wheel groups are slidably connected with the column tracks on the columns;

[0011] The connecting crossbeam is fixed between the vertical portions of the front portions of the two U-shaped plates; the mounting seat is fixedly connected to the connecting crossbeam;

[0012] A lateral sliding device and a lateral driving device are installed on the mounting seat, and the lateral sliding device includes two guide frames and two upper rails;

[0013] The two guide frames are both provided with sliding blocks, which are slidably connected with the sliding tracks on the mounting seats;

[0014] The two upper rails are respectively mounted on the two guide frames;

[0015] The transverse driving device is used to drive the transverse sliding device to move transversely.

[0016] Optionally, the two upper rails are detachably connected to the two guide frames respectively, so that the track gauge can be adjusted.

[0017] By adjusting the installation position of the upper track accordingly, the track spacing can be changed, and tracks of different specifications can be matched. Therefore, when the shuttle car's outer dimensions change, causing the trolley gauge to change, the transportation requirements of different shuttle cars can also be met.

[0018] Optionally, the guide frame includes a horizontal welding plate and a vertically fixed guide side plate; the sliding block is installed on the horizontal welding plate, and the two upper rails are respectively bolted to the two guide side plates.

[0019] Bolt holes at different positions are arranged on the guide side plates, which are connected by bolts. By adjusting the positions of the bolt mounting holes, the mounting position of the upper rail can be adjusted accordingly, and the adjustment is convenient and quick.

[0020] Optionally, a plurality of sliding blocks are installed on each of the horizontal welding plates.

[0021] Multiple sliding blocks are set to make the sliding more stable and smooth, ensuring the sliding stability of the guide frame. The guide frame and the upper track are modularly designed for easy assembly.

[0022] Optionally, the transverse driving device includes a motor, a telescopic device and an intermediate connecting member, the intermediate connecting member connects the two guide frames, and the motor drives the telescopic device to drive the intermediate connecting member to move; the motor is installed on the mounting seat.

[0023] The motor drives the middle connecting piece to move, and then drives the two guide frames to move through the connecting piece, thereby driving the upper track to move, thereby completing the translation of the upper track.

[0024] Optionally, the telescopic device adopts a lead screw.

[0025] In addition to the lead screw, structures such as cylinders that can complete telescopic movements can also be used. These can be applied to the present application and can be selected according to different situations and needs, and are all within the scope of protection of the present application.

[0026] Optionally, the cargo platform frame is also equipped with a track precision docking detection device, a shuttle approach device, and a shuttle lateral precision positioning device, which are used to monitor whether the upper track and the shelf track are accurately docked, whether the shuttle is approaching, and whether the shuttle is accurately in place on the upper track.

[0027] Through the above three devices, the track position and the shuttle position can be accurately determined, thereby ensuring the precise docking of the upper track and the shelf track, so that the shuttle can be accurately positioned.

[0028] Optionally, the track precise docking detection device, the shuttle approach device and the shuttle lateral precise positioning device can all use infrared ranging sensors.

[0029] Infrared ranging sensors are commonly used distance measuring devices with high accuracy and easy use.

[0030] Optionally, a buffer block and an assembly detection switch mounting seat are also installed on the connecting beam.

[0031] The buffer block is used to cushion the shuttle and prevent the shuttle from being directly mounted on the crossbeam.

[0032] Based on the above-mentioned second purpose, the present invention provides a car lifting machine, the car lifting machine, and the car lifting machine includes the car lifting machine cargo platform as described above.

[0033] The cargo platform of the vehicle hoist provided by the present invention is composed of a U-shaped plate, a transverse beam and a mounting seat, forming an L-shaped frame. The U-shaped plate, a transverse beam and a mounting seat are arranged symmetrically on both sides, and are the main supporting components of the cargo platform frame. The entire cargo platform frame is a structural form of profiles and plates, which are finally connected by bolts. The installation is simple and convenient, and the existing double-layer profile structure is avoided, and the vertical height of the cargo platform frame is reduced.

[0034] Moreover, in the past, cargo platforms often adopted a four-frame four-wheel structure, and its guide wheel group was installed on the crossbeam frame of the frame, and ran in the vertical direction along the column track of the car lift, so the sliding and synchronization were poor, and the wear on the guide wheels was serious. The car lift cargo platform provided by the present invention has a cargo platform frame including a stack of U-shaped plates, and multiple guide wheel groups are arranged on the inner side of the horizontal connecting part and the vertical part of the back of the U-shaped plate; the two U-shaped plates are respectively used to clamp on the two columns, and the guide wheel groups are slidably connected with the tracks on the columns. This scheme adopts multiple guide wheel groups, which are directly installed on the two groups of U-shaped plates of the L-shaped frame of the cargo platform. The guide wheel groups are in contact with multiple side surfaces of the column track of the car lift, which ensures that the cargo platform can slide up and down more smoothly along the track direction, and can make the operation of the cargo platform safer and more stable. At the same time, the structure is relatively simple and the appearance is beautiful.

[0035] At the same time, the two upper rails of the cargo platform can move horizontally, thus ensuring that the upper rails and the shelf rails can be accurately docked, allowing the shuttle car to run smoothly between the car lift and the shelf rails, with high flexibility in use.

[0061] The motor 16 drives the intermediate connecting member 13 to move, and then drives the two guide frames 11 to move through the intermediate connecting member 13, thereby driving the upper rail 12 to move, thereby completing the translation of the upper rail 12.

[0062] Furthermore, the telescopic device 14 adopts a lead screw.

[0063] In addition to the lead screw, structures such as cylinders that can complete telescopic movements can also be used. These can be applied to the present application and can be selected according to different situations and needs, and are all within the scope of protection of the present application.

[0064] Preferably, a control component is also installed on the mounting seat 15 for controlling the motor 16 .

[0065] The control component 17 is a commonly used motor switch and gear knob, etc., which can be used for the power switch and the forward and reverse rotation and gear position of the motor, etc. It is a commonly used circuit and will not be described in detail here.
