Description

Technical Field

[0001] This invention relates to the field of four-way vehicle racking technology, and in particular to a four-way vehicle racking with a height-adjustable guide rail switching device. Background Technology

[0002] With the development of technology, especially the invention of four-way freight vehicles, the capacity of freight warehousing has been greatly improved. In response to the requirements of using four-way vehicles, guide rails have been set up on traditional racks to facilitate their movement. However, current racks can only be used on the first plane of four-way vehicles and cannot move horizontally on crisscrossing racks. This greatly limits the operation of four-way vehicles and also results in low stability and efficiency in the loading and unloading of goods on four-way vehicles. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that current racks can only be used on the first plane by four-way carts, and cannot move horizontally on crisscrossing racks, which greatly limits the operation of four-way carts. At the same time, the stability and efficiency of loading and unloading of goods on four-way carts are not high.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a four-way vehicle rack with a height-adjustable guide rail switching device, including a rack body, wherein a transverse guide rail for cooperating with the movement of a four-way vehicle is fixedly installed at the center of each layer inside the rack body, and symmetrically arranged longitudinal lifting guide rails are fixedly installed on both sides of the lateral opening of the transverse guide rail on the outer surface of the rack body, and an electrically controlled external lifting platform for controlling the lifting and adjustment of the four-way vehicle is movably installed on the outer surface of the rack body through the longitudinal lifting guide rail, and a bottom side guide rail that cooperates with the electrically controlled external lifting platform is fixedly installed on the bottom of the outer side of the rack body.

[0005] The lower surface of the horizontal guide rail is fixed with a downwardly protruding bottom guide rail at the lateral opening position, and an electrically controlled translation support plate is installed inside the bottom guide rail.

[0006] The upper surface of the horizontal guide rail has a strip-shaped transition opening at the bottom guide rail position for cooperating with the electrically controlled translation support plate.

[0007] The longitudinal lifting guide rail is internally fixedly equipped with a longitudinal lifting screw. The electrically controlled external lifting platform includes an external lifting frame movably sleeved on the outside of the longitudinal lifting guide rail, a lateral lifting arm fixed on the inner side of the external lifting frame, a lateral guide cylinder fixed on the inner walls of both sides of the external lifting frame, an internal thread adjusting cylinder movably installed inside the lateral guide cylinder, and a lateral adjusting motor fixed at the bottom of the lateral lifting arm. The lateral adjusting motor is movably driven by the adjusting gears on the two adjusting shafts and the internal thread adjusting cylinder.

[0008] The electrically controlled translation support plate includes an electrically controlled strut fixed inside the bottom guide rail, a top support platform set in the recessed opening at the upper end of the strip transition opening, and a linkage bracket fixed between the transverse telescopic section of the electrically controlled strut and the lower end of the top support platform.

[0009] The top support platform has an arc-shaped positioning groove on its upper surface that matches the bottom conveyor wheel of the four-way vehicle. A pressure control switch is installed on the bottom surface of the arc-shaped positioning groove.

[0010] The upper surface of the shelf body is equipped with electrically controlled flipping guide frames on both sides of the horizontal guide rail.

[0011] The electrically controlled tilting guide frame includes a bottom assembly frame fixed inside the shelf body, a first tilting adjustment arm movably installed on one side of the bottom assembly frame, a second tilting adjustment arm movably installed on the other side of the bottom assembly frame, a top lifting plate movably installed between the first tilting adjustment arm and the second tilting adjustment arm, and an electrically controlled lateral support rod movably installed on the other side of the bottom assembly frame for controlling the first tilting adjustment arm.

[0012] Infrared positioning control modules are fixed on the inner sides of both the horizontal and vertical lifting guide rails.

[0013] The top support platform and the lateral lifting arm are misaligned.

[0014] The beneficial effects of this invention are:

[0015] (1) The four-way vehicle rack with height adjustable guide rail switching device of the present invention adjusts the lifting of the four-way vehicle by means of an electrically controlled external lifting platform located on the longitudinal lifting guide rail, which allows the four-way vehicle to switch between multiple planes, making the operation convenient and quick.

[0016] (2) By using the staggered top support platform and the side lifting arm, the four-way vehicle can be driven away to the outer opening of the horizontal guide rail, and then the side lifting arm can easily separate and lift it, which greatly facilitates the lifting control and ensures the stability of the four-way vehicle when switching heights.

[0017] (3) By adopting an electronically controlled telescopic structure design, it can be coordinated with the four-way vehicle to extend to the outer opening of the horizontal guide rail to ensure loading and unloading adjustment;

[0018] (4) An arc-shaped positioning groove is provided on the upper surface of the top support platform to cooperate with the bottom conveyor wheel of the four-way vehicle. At the same time, a pressure control switch is installed on the bottom surface of the arc-shaped positioning groove, which can position the four-way vehicle and improve the stability of the four-way vehicle when it is extended and retracted.

[0019] (5) The structure of the whole device is reasonable and will not occupy the internal and external space of the shelves. It adopts an external structure design, which is convenient for popularization and promotion. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Figure 1 , Figure 2 , Figure 3 and Figure 4 The four-way vehicle rack shown includes a rack body 1. Inside the rack body 1, a transverse guide rail 2 for cooperating with the movement of the four-way vehicle is fixedly installed at the center of each layer. On the outer side of the rack body 1, symmetrically arranged longitudinal lifting guide rails 3 are fixedly installed on both sides of the lateral opening of the transverse guide rail 2. An electrically controlled external lifting platform 4 for controlling the lifting and adjustment of the four-way vehicle is movably installed on the outer side of the rack body 1 through the longitudinal lifting guide rails 3. A bottom side guide rail 5 that cooperates with the electrically controlled external lifting platform 4 is fixedly installed at the bottom of the outer side of the rack body 1.

[0028] In order to facilitate the four-way vehicle's export and ensure stability, a bottom guide rail 6 with a downward protrusion is fixed on the lower surface of the transverse guide rail 2 at the side opening position, and an electrically controlled translation support plate 7 is installed inside the bottom guide rail 6.

[0029] To facilitate top adjustment, the upper surface of the horizontal guide rail 2 is provided with a strip-shaped transition opening 8 at the position of the bottom guide rail 6 for use with the electrically controlled translation support plate 7.

[0030] To facilitate electric lifting, a longitudinal lifting screw 9 is fixedly installed inside the longitudinal lifting guide rail 3. The electric external lifting platform 4 includes an external lifting frame 41 movably sleeved on the outside of the longitudinal lifting guide rail 3, a lateral lifting arm 42 fixed on the inner side of the external lifting frame 41, a lateral guide cylinder 43 fixed on the inner walls of both sides of the external lifting frame 41, an internal thread adjusting cylinder 44 movably installed inside the lateral guide cylinder 43, and a lateral adjusting motor 45 fixed at the bottom of the lateral lifting arm 42. The lateral adjusting motor 45 is movably driven by the adjusting gear 46 on the two adjusting shafts and the internal thread adjusting cylinder 44.

[0031] The lateral adjustment motor 45 is existing technology. It drives the adjustment gear 46 to rotate, thereby driving the internal thread adjustment cylinder 44 to rotate. An annular tooth groove that cooperates with the adjustment gear 46 is provided on the outer side of the internal thread adjustment cylinder 44. The adjustment gear 46 and the annular tooth groove mesh with each other for transmission.

[0032] To facilitate the electrically controlled translation adjustment, the electrically controlled translation support plate 7 includes an electrically controlled strut 71 fixed inside the bottom guide rail 6, a top support platform 72 set in the recessed opening at the upper end of the strip transition opening 8, and a linkage bracket 73 fixed at the lower end of the transverse telescopic section of the electrically controlled strut 71 and the top support platform 72.

[0033] The electric control strut 71 is existing technology. It controls the adjustment of the linkage bracket 73 by telescoping, thereby driving the top support platform 72 to move horizontally at the upper end of the strip transition port 8, which facilitates the movement of the four-way vehicle out of the transverse guide rail 2.

[0034] To facilitate bottom positioning and control, the upper surface of the top support platform 72 is provided with an arc-shaped positioning groove 74 that matches the bottom conveyor wheel of the four-way vehicle. A pressure control switch 75 is installed on the bottom surface of the arc-shaped positioning groove 74.

[0035] When the four-way vehicle moves along the transverse guide rail 2 onto the top support platform 72, the drive wheels on the outer bottom of the four-way vehicle are guided into the arc-shaped positioning groove 74. Then, by squeezing the pressure control switch 75 on the inner bottom surface, the electric control strut 71 is closed, and then the electric control external lifting platform 4 is raised to adjust the height of the four-way vehicle.

[0036] To facilitate lateral assembly, adjustment, and support, the upper surface of the shelf body 1 is equipped with electrically controlled tilting guide frames 9 on both sides of the horizontal guide rail 2.

[0037] To facilitate the rapid transfer of goods from the shelf to the four-way cart and to ensure the smooth transfer of goods from the four-way cart to the shelf, while also providing bottom support for the goods during normal operation, the electrically controlled tilting guide frame 9 includes a bottom side assembly frame 91 fixed inside the shelf body 1, a first tilting adjustment arm 92 movably installed on one side of the bottom side assembly frame 91, a second tilting adjustment arm 93 movably installed on the other side of the bottom side assembly frame 91, a top lifting plate 94 movably installed between the first tilting adjustment arm 92 and the second tilting adjustment arm 93, and an electrically controlled lateral support rod 95 movably installed on the other side of the bottom side assembly frame 91 for controlling the first tilting adjustment arm 92.

[0038] The electrically controlled lateral support rod 95 is existing technology. It controls the adjustment of the first tilting adjustment arm 92 by telescoping, and then synchronously drives the second tilting adjustment arm 93 to tilt, thereby driving the top lifting plate 94 to rise and fall.

[0039] To cooperate with infrared positioning and ensure the accuracy of adjustment and control, infrared positioning control modules 10 are fixed on the inner sides of both the horizontal guide rail 2 and the vertical lifting guide rail 3.

[0040] The infrared positioning control module 10 uses the reflective lens on the outer surface of the four-way vehicle to reflect infrared light, thereby completing the positioning and enabling precise positioning of the four-way vehicle. This facilitates the control of the four-way vehicle, the electrically controlled external lifting platform 4, the electrically controlled translation support plate 7, and the electrically controlled tilting guide frame 9.

[0041] To ensure that they do not interfere with each other during lifting and adjustment, the top support platform 72 and the lateral lifting arm 42 are staggered.

[0042] When the four-way vehicle loaded on the top support platform 72 moves outward horizontally, the lateral lifting arm 42 lifts the four-way vehicle from bottom to top, thereby separating and lifting the four-way vehicle from the top support platform 72. Then the top support platform 72 retracts, making it convenient for the controlled external lifting platform 4 to lift and lower.

[0043] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
