Description

Technical Field

[0001] This invention belongs to the field of four-way shuttle emergency rescue technology, and specifically relates to an all-around emergency rescue vehicle with four-way shuttle capability. Background Technology

[0002] Due to long-term high-intensity operation, complex working conditions (such as temperature and humidity changes, dusty environment, vibration and shock) and the increase in the service life of the equipment, the four-way shuttle will inevitably experience problems such as mechanical wear, electrical failure, battery aging or abnormal control system, which will cause it to be unable to operate normally or even completely shut down.

[0003] When such faults occur, conventional remote diagnostics and automatic reset methods are often insufficient to resolve the issue, requiring maintenance personnel to enter the external shelving for on-site troubleshooting and repair. This process presents numerous challenges:

[0004] The racking systems operated by four-way shuttles are typically multi-layered, high-density structures with narrow aisles and significant height, resulting in severely limited space. Maintenance personnel must carry tools, spare parts, and testing equipment within this confined space, making operation extremely inconvenient and severely impacting maintenance efficiency. Especially in the external racking areas at higher levels, the need for lifting platforms or ladders further increases the complexity of the operation.

[0005] Currently, most warehouses only have steel mesh or maintenance platforms installed in the main aisles or some sub-aisles for walking, while many intermediate areas and shuttle bus routes lack effective protection. If maintenance personnel step on unreinforced pallet supports or areas with weak mesh, they are highly susceptible to falls and other accidents. Furthermore, small parts or tools falling from heights can also injure people below, creating secondary risks.

[0006] In conclusion, the existing four-way shuttle maintenance mode has obvious shortcomings in terms of safety, convenience and efficiency. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an all-around emergency rescue vehicle with four-way shuttle, so as to solve the problems mentioned in the background technology.

The screw knob passes through the first through hole and the second through hole, through the limiting member and the first side mesh assembly, and is threadedly connected to the internal threaded cylinder to reinforce the first side mesh assembly. In actual use, both the first and second side mesh assemblies can be made of lightweight materials, making it convenient for users to disassemble and assemble.

[0018] In a preferred embodiment, a hand crank is provided on the left and right sides of the arm crank and connected by a rotating shaft. A transmission gear three is provided in the middle of the rotating shaft, which is connected to the upper end of the transmission chain one through the transmission gear three. The transmission chain one is arranged in an L-shaped structure, and its curved part is tensioned and guided by a tension gear one.

[0019] The horizontal transmission assembly includes a transmission rod 1. The left and right ends of the transmission rod 1 are fixedly connected to the vehicle body via a bearing 2 and a bearing seat 1, respectively. A transmission gear 1 is keyed to the left and right sides of the transmission rod 1, and a transmission gear 2 is keyed to the middle of the transmission rod 1 for transmission connection with a transmission chain 1.

[0027] After adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. By setting side net component one and side net component two, the movable side net component one and side net component two not only facilitate maintenance personnel to quickly disassemble side net component one and side net component two when needed, but also facilitate their subsequent installation, greatly reducing the operation difficulty of maintenance personnel and improving the convenience of subsequent maintenance equipment. When the entire device travels in the external rack, it can provide sufficient protection to prevent maintenance personnel from falling.

[0028] 2. By setting up a drive component, maintenance personnel can easily output power through the arm crank wheel and chain drive to realize the power output for the movement of the rescue vehicle.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] As the first embodiment of the present invention:

[0046] Please see Figures 1 to 10 A four-way shuttle all-around emergency rescue vehicle includes: a rescue vehicle 100, a side net assembly 200 for side protection installed on the left and right sides of the upper end of the rescue vehicle 100, a side net assembly 300 installed on the left and right sides of the upper end of the rescue vehicle 100, the two side net assemblies 200 being movably connected to the two side net assemblies 300 via multiple screws and knobs, and a drive assembly 400 for driving the entire device to move installed on the upper side of the rescue vehicle 100;

[0047] The rescue vehicle 100 includes a vehicle body 150. A panel 140 is fixed to the upper end of the vehicle body 150. A battery cover 120 is hinged to the upper surface of the panel 140 near the side of the drive assembly 400 via a hinge 1. A toolbox cover 130 is hinged to the upper surface of the panel 140 at the rear side of the drive assembly 400 via a hinge 2. A toolbox 170 for storing tools is installed in the middle of the interior of the vehicle body 150. It is located directly below the toolbox cover 130 and is movably abutted against it.

[0048] Two hanging plates 220 are welded to the upper inner part of both side net components 200, and two hanging plates 330 are welded to the upper inner part of both side net components 300.

[0049] The drive assembly 400 includes a support column 420. An arm rocker wheel 410 is rotatably mounted on the upper end of the support column 420 via a bearing. The arm rocker wheel 410 is connected to the upper end of a transmission chain 430, with the upper end of the transmission chain 430 located inside the support column 420 and the lower end located inside the vehicle body 150 and connected to a horizontal transmission assembly 440. Both ends of the horizontal transmission assembly 440 are connected to a Y-axis transmission assembly 460, and the two sides of the horizontal transmission assembly 440 are connected to an X-axis transmission assembly 450. In actual use, the battery assembly 160 is electrically connected to the power supply of two electric cylinders 451 via wires. When a reversing operation is required, the two electric cylinders 451 are started by powering the battery assembly 160, thereby driving the two mounting beams 454 to move up and down to achieve reversing. The two electric cylinders 451 are synchronous electric cylinders 451, which can achieve synchronous movement.

[0050] The vehicle body 150 has a battery box located directly below the battery cover 120 for installing the battery assembly 160. The four corners of the panel 140 each extend downward to form a rectangular notch-shaped insertion slot 110. A rectangular tube is welded to each of the four corners of the vehicle body 150, and its internal cross-sectional dimensions and structure match the dimensions and structure of the insertion slot 110. The four corners of the panel 140 are recessed downward to form four circular grooves. In actual use, the side of the vehicle body 150 has reserved holes for installing the drive assembly 400, as shown in the attached diagram of the instruction manual.

[0051] Each of the two side net components 200 has a slot 230 on its upper front and rear sides respectively. The slot 230 on one side net component 200 is used to insert and connect with the lower part of the hanging plate 220 on the other side net component 200. The cross-sectional dimensions and structure of the slot 230 on both side net components 200 are matched with the cross-sectional dimensions and structure of the lower part of the hanging plate 220.

[0052] The spacing between the two mounting plates 220 on the same side mesh assembly 200 matches the spacing between the two slots 230. The mounting plate 220 has an inverted L-shaped structure. Both side mesh assemblies 200 have a through hole 210 formed from left to right on the side closest to the two side mesh assemblies 300. The lower front and lower rear sides of the two side mesh assemblies 200 are respectively provided with cylindrical short rods, which are movably inserted into the circular groove.

[0053] Each of the two side net components 300 has a slot 340 on its upper left and right sides respectively. The slot 340 on one side net component 300 is used to insert and connect with the lower part of the hanging plate 330 on the other side net component 300. The cross-sectional dimensions and structure of the slots 340 on the two side net components 300 are matched with the cross-sectional dimensions and structure of the lower part of the hanging plate 330. The spacing between the two hanging plates 330 on the same side net component 300 is matched with the spacing between the two slots 340. The hanging plate 330 has an inverted L-shaped structure.

[0054] Multiple limiting members 310 are welded to the side of each of the two side mesh components 200 near the two side mesh components 1. Each limiting member 310 is an angle iron with a U-shaped cross-section, and its outer part is provided with an internal threaded cylinder 320. Its interior extends through the internal threaded cylinder 320 to form a through hole 2.

[0055] The number and distribution of through holes 2 match the number and distribution of through holes 1 210. The axes of through holes 1 210, through holes 2, and the internal threaded cylinder 320 on the same side are all collinear. The screw knob passes through through holes 1 210 and through holes 2, through the limiting member 310 and the side mesh assembly 1 200 and is threadedly connected to the internal threaded cylinder 320 to reinforce the side mesh assembly 1 200. In actual use, both side mesh assembly 1 200 and side mesh assembly 2 300 can be made of lightweight materials to facilitate disassembly and assembly by users.

[0056] Specifically, by setting up side net assembly 200 and side net assembly 300, in actual use, if the operator needs to disassemble side net assembly 200 or side net assembly 300 on one side, they can first loosen the screw knobs that are fixed to them. For example, to remove side net assembly 200 on the right side of the vehicle body 150, the user first releases the screw knobs connected to side net assembly 300 on both sides from the internal threaded cylinder 320, and then pulls it out from the limiting member 310 through through hole 210 and through hole 2. Turn the screw knob to release the side net assembly 200 on that side. Then, the user can lift the side net assembly 200 upwards. At this time, the short cylindrical rod at the lower end of the side net assembly will disengage from the circular groove on the panel 140. After the lower end of the side net assembly 200 reaches the top of the side net assembly 300, the side net assembly 200 can be completely removed. Then, the side net assembly 200 can be hung on the remaining side net assembly 200 or the other two side net assemblies 300 via the two hanging plates 220 on it.

[0057] For example, side net assembly 200 is mounted on the remaining side net assembly 200 via its two mounting plates 220. Specifically, the removed side net assembly 200 is rotated 180 degrees so that the side with the mounting plates faces the outside of the unremoved side net assembly 200. Then, the lower ends of the two mounting plates are aligned with the two slots 230 and inserted downwards, thereby mounting the removed side net assembly 200 onto the unremoved side net assembly 200. During installation, the reverse steps are performed to achieve quick installation. The side net assembly 200... The disassembly and assembly steps are the same as those for side net assembly 1 200. This not only makes it convenient for maintenance personnel to quickly disassemble side net assembly 1 200 and side net assembly 2 300 when needed, but also facilitates their subsequent installation, greatly reducing the operational difficulty for maintenance personnel and improving the convenience of subsequent maintenance equipment. When the entire device travels within the external rack, it can provide sufficient protection to prevent maintenance personnel from falling (if necessary, the hoisting scenario of the four-way shuttle car can be quickly set up according to the needs of the installation positions of side net assembly 1 200 and side net assembly 2 300).

[0058] As a second embodiment of the present invention:

[0059] Please see Figures 1 to 10 A hand crank is provided on the left and right sides of the arm crank 410 and connected by a rotating shaft. A transmission gear three is provided in the middle of the rotating shaft, which is connected to the upper end of the transmission chain 430 through the transmission gear three. The transmission chain 430 is arranged in an L-shape, and its curved part is tensioned and guided by the tension gear one.

[0060] The horizontal transmission assembly 440 includes a transmission rod 442. The left and right ends of the transmission rod 442 are fixedly connected to the vehicle body 150 via a bearing and a bearing seat, respectively. A transmission gear 444 is keyed to the left and right sides of the transmission rod 442. A transmission gear 445 is keyed to the middle of the transmission rod 442 for transmission connection with the transmission chain 430. The middle part of the transmission rod 442 is rotatably mounted inside the vehicle body 150 via a mounting base 441. A right-angle gear 443 is keyed to the left and right sides of the transmission rod 442 for driving the X-axis transmission assembly 450. The two right-angle gears 443 are located inside the two transmission gears 444, respectively.

[0061] Y-direction transmission assembly 460 includes a transmission chain 2 461. The front and rear sides of the transmission chain 2 461 are respectively connected to four walking wheels 2 462 through a transmission gear 4. Each walking wheel 2 462 is rotatably connected to the vehicle body 150 through a bearing 3 and a bearing seat 2.

[0062] Each walking wheel 462 has a keyed transmission gear 4 on its inner side. The transmission chain 461 is connected to the transmission gear 444 on the side near the transmission rod 442. Tensioning gears 2 are rotatably installed on the front, rear and directly below the position where the transmission chain 461 is connected to the transmission gear 444 to guide and tension the transmission chain 461.

[0063] The X-axis transmission assembly 450 has a U-shaped structure, which includes two axisymmetrically arranged mounting beams 454, and a transmission rod 457 is rotatably mounted on the left and right sides between the two mounting beams 454, respectively.

[0064] The front and rear sides of each transmission rod 457 are fixedly connected to the bottom of the vehicle body 150 through a fixed seat 458, and the transmission rod 457 is rotatably connected to the fixed seat 458. The front and rear ends of each transmission rod 457 are respectively connected to a universal joint 455 fixing plate. The front and rear ends of each transmission rod 457 are respectively connected to the axle of the first traveling wheel 452 mounted on the mounting beam 454 through a universal joint 455.

[0065] Each transmission rod 457 is equipped with a right-angle gear 456 near the transmission rod 442. The right-angle gear 456 meshes with the right-angle gear 443 on the transmission rod 442 to drive the transmission rod 457 to rotate.

[0066] Each mounting beam 454 has a guide groove opened inward on the left front side, the rear side, the right front side, and the right rear side, which is slidably connected to multiple guide rails 453 to guide and limit the mounting beam 454 in the vertical direction. The lower ends of the multiple guide rails 453 are all fixedly connected to the bottom of the vehicle body 150.

[0067] Each mounting beam 454 has an electric cylinder 451 fixed in the middle. The top of the electric cylinder 451 is fixedly connected to the panel 140, and its lower end is fixedly connected to the mounting beam 454 through a piston rod to drive the mounting beam 454 to move up and down, thereby completing the reversal operation of the movement direction of the rescue vehicle 100.

[0068] Based on the first embodiment described above, further, by setting the drive assembly 400, in actual use, maintenance personnel manually rotate the arm crank 410 mounted on the support column 420 to drive the transmission chain 430. The forward and reverse rotation of the handwheel can adjust the forward direction, i.e., the front-back or left-right direction. Since the lower end of the transmission chain 430 is connected to the horizontal transmission assembly 440, it can drive the horizontal transmission assembly 440 to move when the arm crank 410 is turned. Furthermore, since the horizontal transmission assembly 440 is connected to the X-direction transmission assembly 450 and the Y-direction transmission assembly 460, the X-direction transmission assembly 450 and the Y-direction transmission assembly 460 can be driven to move synchronously when the horizontal transmission assembly 440 is running. When moving in the front-back direction, the traveling wheel 452 in the X-direction transmission assembly 450 is lifted and does not contact the track on the external shelf. Only the X-direction transmission assembly 450... The second walking wheel 462 in the middle contacts the track on the external shelf. At this time, when the maintenance personnel rotate the arm crank 410, it drives the horizontal transmission component 440 to rotate through the transmission chain 430 and the transmission gear 445. Although the rotating transmission rod 442 drives the X-direction transmission component 450 through the right angle gear 443, the first walking wheel 452 in the X-direction transmission component 450 is lifted and does not contact the track on the external shelf, so the first walking wheel 452 does not have a driving effect. The transmission rod 442 drives the transmission chain 461 on the Y-direction transmission component 460 to rotate through the transmission gear 445 on it. Then, the transmission chain 461 drives the second walking wheel 462, thereby realizing the synchronous driving of multiple second walking wheels 462, and further driving the entire rescue vehicle 100. The specific driving direction is determined by the direction of rotation of the arm crank 410 by the maintenance personnel.

[0069] When moving left or right, pressing the power control button mounted on the support column 420 simultaneously supplies power to the two electric cylinders 451. The two electric cylinders 451 start synchronously, pushing the two mounting beams 454 downwards. This causes the first traveling wheel 452 in the Y-axis transmission assembly 460 to move downwards, making it contact the transverse track on the external shelf. Meanwhile, the second traveling wheel 462 is lifted and disengaged from the longitudinal track due to the downward movement of the first traveling wheel 452. At this point, when the maintenance personnel rotate the arm crank 410, it drives the horizontal transmission assembly 440 to rotate via the transmission chain 430 and the transmission gear 445. Although the transmission rod 442 drives the transmission chain 461 on the Y-axis transmission assembly 460 to rotate through the transmission gear 445 on it, the rotating walking wheel 462 does not have a driving effect because it is off the track. The rotating transmission rod 442 drives the two transmission rods 457 to rotate through the right angle gear 443 and the right angle gear 456 on the transmission rod 457, which drives the universal joints 455 at both ends to rotate, thereby driving the connected walking wheel 452 to rotate, and further driving the entire rescue vehicle 100. The specific direction of travel is determined by the direction of rotation of the arm crank 410 by the maintenance personnel.

[0070] Maintenance personnel can easily output power through the arm crank 410 via chain drive to enable the rescue vehicle 100 to move. The rescue vehicle 100 can be reversed by power output through the low-voltage electric cylinder 451.
