Description

Technical Field

[0001] This application relates to the field of equipment maintenance technology, and in particular to an AGV emergency vehicle. Background Technology

[0002] AGV stands for Automated Guided Vehicle, and it is widely used in the automotive manufacturing industry due to its flexibility, high degree of automation, and high safety. When an AGV malfunctions while transporting automotive parts, it will remain in place, waiting for maintenance personnel to remove it from the site for troubleshooting and repair. In related technologies, forklifts and overhead cranes are typically used in conjunction to move the AGV to the repair area. However, the inventor believes that this method of using forklifts and overhead cranes to move AGVs can easily cause secondary damage to the AGV, hindering troubleshooting and repair. Utility Model Content

[0003] In order to improve the problem that using forklifts and overhead cranes to move AGVs can easily cause secondary damage to AGVs, this application provides an AGV emergency vehicle.

[0004] The AGV emergency vehicle provided in this application adopts the following technical solution:

[0005] An AGV emergency trolley includes a maintenance trolley, a lifting bracket mounted on the maintenance trolley, and a jack assembly mounted on the maintenance trolley for driving the lifting bracket to move up and down; the lifting bracket includes a side bracket and a lifting platform connected to the side bracket for lifting the AGV, and the jack assembly includes a jack mounted on the maintenance trolley and a lifting claw mounted on the output end of the jack and abutting against the side bracket.

[0006] By adopting the above technical solution, during emergency maintenance, two operators move two AGV emergency trolleys to the left and right sides of the malfunctioning AGV, and fix the lifting platform of the AGV emergency trolley to the bottom of the AGV. Then, two jack assemblies are used to lift the two lifting brackets vertically to the same height. Finally, two maintenance trolleys are used to move the malfunctioning AGV to the maintenance location. This improves the problem of secondary damage to the AGV that is easily caused by using forklifts and overhead cranes to move the AGV.

[0007] Optionally, the maintenance trolley has a vertically arranged linear guide rail; the back of the lifting bracket has a linear slider that is slidably arranged on the linear guide rail.

[0008] By adopting the above technical solution, the maintenance trolley and the lifting bracket are connected by linear guide rails and linear sliders, which guide their lifting direction and improve the stability of the jack assembly for the vertical lifting of the lifting bracket.

[0009] Optionally, the number of linear guide rails is two and they are symmetrically arranged on both sides of the lifting claw. The lifting bracket is provided with two linear sliders, and the two linear sliders are arranged in a one-to-one correspondence with the linear guide rails.

[0010] By adopting the above technical solution, two linear guide rails are symmetrically arranged on both sides of the lifting claw, and two linear sliders corresponding one-to-one with the linear guide rails are arranged on the lifting bracket, which helps to further improve the stability of the vertical lifting bracket of the jack assembly.

[0011] Optionally, a limiting structure is provided between the maintenance trolley and the lifting bracket to limit the lifting range of the lifting bracket; the limiting structure includes an upper limit block installed on the maintenance trolley and a limiting plate installed on the side bracket and located below the upper limit block.

[0012] By adopting the above technical solution, a limiting structure is set between the maintenance trolley and the lifting bracket, which limits the vertical lifting height of the lifting bracket and helps reduce the risk of the lifting bracket falling off the linear guide rail due to excessive lifting. When the lifting bracket is raised to a certain height, the limiting plate of the side bracket abuts against the upper limit block of the maintenance trolley, thereby limiting the lifting height of the lifting bracket and helping to maintain the horizontal balance of the lifting platform.

[0013] Optionally, both sides of the side bracket are provided with a first limiting block to restrict the lateral sliding of the AGV, and the first limiting block extends away from the maintenance trolley.

[0014] By adopting the above technical solution, first limiting blocks are set on both sides of the side bracket, which helps the side bracket to confirm the relative position in the width direction between itself and the AGV.

[0015] Optionally, the side bracket is provided with a protective top block on the side facing away from the maintenance trolley for the AGV to abut against. There are two protective top blocks, which are arranged symmetrically on the left and right.

[0016] By adopting the above technical solution, the protective top blocks prevent the AGV from directly contacting the side support, reducing the probability of relative impact between the two and helping to protect both the AGV and the lifting support. The symmetrical arrangement of the two protective top blocks helps to confirm the relative position of the side support and the AGV along their length and secures the AGV to the lifting support, preventing the maintenance trolley from tilting further during subsequent lifting.

[0017] Optionally, the top surface of the lifting platform is provided with a support pad for supporting the bottom surface of the AGV, and the support pad is fixed to the top surface of the lifting platform by screws.

[0018] By adopting the above technical solution, a support pad is set on the top surface of the lifting platform so that it abuts against the bottom of the AGV. At the same time, the frictional resistance of the bottom of the AGV is increased, which helps to prevent the maintenance trolley from slipping and falling off during the transfer process, causing secondary damage.

[0019] Optionally, the top surface of the lifting platform is also provided with two limiting shafts, which are arranged symmetrically on the left and right.

[0020] By adopting the above technical solution, the bottom of the AGV has a limiting hole structure that cooperates with the limiting shaft. The lifting platform is fixed by the limiting shaft and the limiting hole at the bottom of the AGV, so that the AGV is not easy to move during the lifting process, thereby improving the stability of the lifted AGV.

[0021] Optionally, the maintenance trolley is equipped with a caster assembly at its bottom. The caster assembly includes two main casters arranged symmetrically on the left and right and an auxiliary caster arranged on one side of the two main casters. The maintenance trolley is threadedly equipped with a lifting ring assembly for limiting the rotation of the main casters.

[0022] By adopting the above technical solution, the omnidirectional wheel assembly makes the AGV emergency trolley move more flexibly when the AGV is not raised. After the AGV emergency trolley is equipped with the AGV, the rotation of the main omnidirectional wheels is uniformly restricted by the rotating lifting ring assembly, making the movement of the maintenance trolley more stable and helping to improve the convenience of maintenance personnel moving the AGV.

[0023] Optionally, the maintenance trolley is provided with a handrail mounting component and a support handrail on the side facing away from the lifting bracket; the support handrail is rotatably mounted on the handrail mounting component and has a vertical state, and a support spring is also provided between the support handrail and the handrail mounting component to drive the support handrail to be in a vertical state.

[0024] By adopting the above technical solution, the support handle facilitates the movement of the maintenance trolley by maintenance personnel. The support spring helps keep the support handle vertical when the maintenance trolley is not in operation.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. An AGV emergency trolley, which helps to improve the problem that the use of forklifts and overhead cranes to move AGVs can easily cause secondary damage to AGVs by fixing the faulty AGV to a lifting bracket, using a jack assembly to vertically lift the lifting bracket, and then moving the maintenance trolley.

[0027] 2. By setting two linear guide rails and two corresponding linear sliders, the stability of the jack assembly when vertically lifting the support frame can be further improved;

[0028] 3. By setting a limiting structure, when the AGV is lifted to a certain height, the limiting plate abuts against the upper limit block, thereby limiting the lifting height of the lifting bracket and preventing it from falling off due to excessive lifting height. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses an AGV emergency vehicle. (Refer to...) Figure 1 The AGV emergency trolley includes a maintenance trolley 1, a lifting bracket 2 mounted on the maintenance trolley 1, and a jack assembly mounted on the maintenance trolley 1 for driving the lifting bracket 2 to rise and fall. The maintenance trolley 1 has a mounting slot 11 in the middle for mounting the jack assembly.

[0038] Reference Figure 1 The lifting bracket 2 is installed at the front end of the maintenance trolley 1. The lifting bracket 2 includes a side bracket 21 and a lifting platform 22 connected to the front bottom edge of the side bracket 21. The front end of the maintenance trolley 1 is provided with vertically arranged linear guide rails 14, and the back of the side bracket 21 has linear sliders 211 that slide along the linear guide rails 14. In this embodiment, there are two linear guide rails 14, symmetrically arranged on the front side of the maintenance trolley 1. The side bracket 21 has two linear sliders 211, each corresponding to one of the linear guide rails 14.

[0039] Reference Figure 1 To reduce the probability of the AGV detaching from the AGV emergency trolley during transportation, first limiting blocks 212 are provided on both sides of the side bracket 21 to restrict the AGV's lateral sliding. The first limiting blocks 212 extend away from the maintenance trolley 1. In this embodiment, the two first limiting blocks 212 are symmetrically arranged at both ends of the side bracket 21 and fixed to the front of the side bracket 21 with screws. The two first limiting blocks 212 have guide ramps 2121 on their opposite sides.

[0040] Reference Figure 1 To further reduce the probability of detachment, a support plate 221 for supporting the bottom of the AGV is provided on the top surface of the lifting platform 22. The support plate 221 is fixed to the top surface of the lifting platform 22 with screws. In this embodiment, the support plate 221 is made of plastic, and its upper surface has a large frictional resistance when in contact with the bottom of the AGV. Two limiting shafts 222 are also provided on the top surface of the lifting platform 22, arranged symmetrically on the left and right sides. In this embodiment, the lifting platform 22 is engaged and fixed to the limiting holes at the bottom of the AGV via the limiting shafts 222, making it less likely for the AGV to move during lifting.

[0041] Reference Figure 1 The side bracket 21 has a protective top block 213 on the side facing away from the maintenance trolley 1 for the AGV to abut against. There are two protective top blocks 213, which are arranged symmetrically on the left and right sides. In this embodiment, two protective top blocks 213 are symmetrically arranged on the front of the side bracket 21, so that the AGV does not directly contact the side bracket 21, reducing the probability of relative impact between the two.

[0042] Reference Figure 1 and Figure 2 A limiting structure is provided between the maintenance trolley 1 and the lifting bracket 2 to restrict the upward range of the lifting bracket 2. The limiting structure includes an upper limit block 41 installed on the maintenance trolley 1 and a limiting plate 42 installed on the side bracket 21 and located below the upper limit block 41. In this embodiment, two upper limit blocks 41 are symmetrically arranged on the left and right sides of the front end of the maintenance trolley 1.

[0043] Reference Figure 3 The maintenance trolley 1 has a caster assembly at its bottom. The caster assembly includes two main casters 121 symmetrically arranged on the left and right sides, and an auxiliary caster 122 located on the side opposite to the lifting bracket 2. A horizontally arranged square mounting plate 123 is mounted on the wheel frame of each main caster 121. The maintenance trolley 1 is threadedly fitted with a lifting ring assembly to restrict the rotation of the main casters 121; each main caster 121 corresponds to one lifting ring assembly. The lifting ring assembly includes two limiting lifting rings 131. Each limiting lifting ring 131 includes a circular portion 1311 and a screw portion 1312 connected to the circular portion 1311 and threadedly mounted to the maintenance trolley 1. The screw portion 1312 is arranged horizontally and faces the square mounting plate 123, so that by adjusting the horizontal position of the limiting ring 131, the screw portion 1312 of the limiting ring 131 can abut against the square mounting plate 123, thereby restricting the rotation of the main caster wheel 121.

[0044] Reference Figure 4 and Figure 5 The bottom of the jack assembly is connected to the mounting slot 11 of the maintenance trolley 1 by screws. The jack assembly includes a jack 31 mounted on the maintenance trolley 1, a lifting claw 32 mounted on the output end of the jack 31, an operating rod 33 detachably mounted on the input port of the jack 31, and a pressure relief rod 34 detachably mounted on the pressure relief port of the jack 31. Specifically, by installing the operating rod 33 on the input port of the jack 31 and pressing it up and down, the output end of the jack 31 is raised; by installing the pressure relief rod 34 on the pressure relief port of the jack 31 and pressing it down, the pressure on the jack 31 is released, allowing the output end of the jack 31 to reset. To facilitate the placement of the operating rod 33 and the pressure relief rod 34, the maintenance trolley 1 is also equipped with a placement bracket 15. The mounting bracket 15 has a first mounting hole 151 for vertically arranging the operating top rod 33 and a second mounting hole 152 for vertically arranging the pressure relief rod 34.

[0045] Reference Figure 2 and Figure 5The lifting claw 32 in the jack assembly is Z-shaped. The lifting claw 32 includes a lifting top plate 321 for connecting to the output end of the jack 31, a lifting side plate 322 connected to the front of the lifting top plate 321 and extending vertically downwards, and a lifting bottom plate 323 connected to the bottom of the lifting side plate 322 and extending horizontally outwards. A lifting pad 324 is mounted on the top of the lifting bottom plate 323, and the lifting pad 324 is fixed to the side bracket 21 by bolts.

[0046] Reference Figure 1 and Figure 6 The maintenance trolley 1 has handrail mounting pieces 16 symmetrically mounted on its rear end, and supporting handrails 17 rotatably mounted on the two handrail mounting pieces 16. Each handrail mounting piece 16 has a first mounting block 161, and each supporting handrail 17 has a first mounting portion 171 that mates with the first mounting block 161. The first mounting block 161 and the first mounting portion 171 are rotatably engaged by a pin. Each handrail mounting piece 16 has a vertically arranged first abutment surface 162 on the upper side of the first mounting block 161. Each supporting handrail 17 has a first abutment block 172 at the first mounting portion 171 for abutting against the first abutment surface 162. When the first abutment block 172 abuts against the first abutment surface 162, the supporting handrail 17 is in a vertical state, that is, the supporting handrail 17 is perpendicular to the ground.

[0047] Reference Figure 6 A support spring 18 is also provided between the support handrail 17 and the handrail mounting piece 16 to drive the support handrail 17 to a vertical position. The support spring 18 is a tension spring, with one end fixed to the handrail mounting piece 16 and the other end fixed to the support handrail 17.

[0048] The implementation principle of an AGV emergency trolley in this application embodiment is as follows: When performing emergency maintenance work, two operators move two AGV emergency trolleys to the left and right sides of the faulty AGV, and fix the lifting platform 22 of the AGV emergency trolley to the bottom of the AGV. Then, two jack assemblies are used to vertically lift the two lifting brackets 2 to the same height. Finally, two maintenance trolleys 1 are used to move the faulty AGV to the maintenance location, which improves the problem that the method of moving AGV with forklifts and overhead cranes is prone to causing secondary damage to the AGV.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
