[0029] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the specific embodiments of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0030] like Figure 1 and Figure 2As shown, the present application discloses a tool vehicle 100 for carrying an AGV chassis 200. The tool vehicle 100 includes a chassis 11, a lifting device 12, and a drive assembly 13. Among them, a movable wheel 111 is installed under the chassis 11, which serves as a bottom support and realizes the movement function of the tool vehicle 100. Optionally, the movable wheel 111 can be configured as a universal wheel. The lifting device 12 includes a guide assembly 121 and a moving assembly 122. Exemplarily, the guide assembly 121 includes two guide rods extending in the height direction and a cross bar for fixing the guide rods. The guide assembly 121 is fixedly mounted on the chassis 11 through the guide rods and / or the cross bar; the moving assembly 122 is movably connected to the guide assembly 121, and the moving assembly 122 can move relative to the guide assembly 121 in the height direction. One end of the drive assembly 13 is connected to the mobile assembly 122, and the other end of the drive assembly 13 is mounted on the chassis 11, or can be mounted on the crossbar of the guide assembly 121 fixed to the chassis 11. The drive assembly 13 is used to provide power to drive the mobile assembly 122 to move along the height direction relative to the guide rod of the guide assembly 121. The tooling vehicle 100 also includes a support assembly 14 mounted on the mobile assembly 122 (see Figure 5 ), the support assembly 14 is located at the bottom of the moving assembly 122, and the support assembly 14 is configured to support the AGV chassis 200 along the height direction. When the moving assembly 122 moves up and down along the height direction, it drives the support assembly 14 to move up and down along the height direction.

[0031] like Figure 1 and Figure 2 As shown, as an implementation, the drive assembly 13 may include a hydraulic cylinder 131 and a hydraulic station 132. The hydraulic station 132 is fixedly mounted on the chassis 11. In the embodiment of the present application, the hydraulic station 132 is fixedly mounted on the side of the chassis 11 opposite the opening 114 of the chassis 11. One end of the hydraulic cylinder 131 is movably connected to the moving assembly 122, and the other end of the hydraulic cylinder 131 is movably connected to the crossbar of the guide assembly 121 fixed to the chassis 11. The hydraulic cylinder 131 is configured to extend in the height direction. Furthermore, the hydraulic cylinder 131 also includes a self-locking mechanism configured to lock the height of the hydraulic cylinder 131. When using the tooling vehicle 100, the hydraulic station 132 is started, and the hydraulic cylinder 131 drives the moving assembly 122 to move upward in the height direction, driving the support assembly 14 and the AGV chassis 200 to move upward away from the ground in the height direction. When the AGV bottom chassis 200 rises to the set height, for example, when the rising height meets the needs of maintenance work, the self-locking mechanism is locked to ensure that the height of the AGV device is fixed. In addition, the self-locking mechanism can also prevent the hydraulic system from abnormally falling to ensure the safety of maintenance personnel.

[0032] As an optional implementation, the drive assembly 13 may include a linear motor, one end of which is movably connected to the guide assembly 121, and the other end of which is movably connected to the moving assembly 122. The linear motor is configured to extend in the height direction. When the tooling vehicle 100 is in use, the linear motor is activated, and the moving assembly 122 moves upward in the height direction, thereby driving the support assembly 14 and the AGV chassis 200 to move upward in the height direction away from the ground.

[0033] Furthermore, if Figure 3 As shown, the chassis 11 is surrounded by a processing space 113 for accommodating the AGV chassis 200. The chassis 11 has an opening 114 in the horizontal direction. The opening 114 is connected to the processing space for accommodating the AGV chassis 200. When in use, the AGV chassis 200 enters the processing space through the opening 114. Further, a longitudinal plane 115 perpendicular to the width direction of the tooling vehicle 100 can be defined (see Figure 4 ), defining a longitudinal plane 115 perpendicular to the width direction of the tooling vehicle 100. At this time, the lifting device 12, drive assembly 13 and support assembly 14 of the tooling vehicle 100 are symmetrically arranged about the longitudinal plane 115, forming a balanced lifting force to lift the AGV chassis 200.

[0034] When in use, the AGV chassis 200 is moved into the disposal space through the opening 114 of the chassis 11 of the tooling vehicle 100. The movable part 142 of the support assembly 14 is now under the AGV chassis 200. The drive assembly 13 is started, and the drive assembly 13 provides power to cause the moving assembly 122 to start moving upward along the guide assembly 121, thereby driving the support assembly 14 to move upward, and finally driving the AGV chassis 200 to rise away from the ground.

[0035] As described above, the tooling vehicle 100 supports the AGV chassis 200 via the support assembly 14, and the drive assembly 13 provides power to drive the movement assembly 122, thereby driving the support assembly 14 to lift the AGV chassis 200 from the ground. During use, the tooling vehicle 100 reduces manual handling, improves work efficiency, and reduces the risk of injury to workers. Furthermore, the use of the tooling vehicle 100 eliminates the previous practice of tilting the AGV chassis 200 for maintenance, eliminating the risk of internal leakage and damage to electronic components after the AGV chassis 200 tilts.

[0036] like Figure 5As shown, as an implementation, the support assembly 14 includes a fixed member 141 and a movable member 142, wherein the fixed member 141 is installed below the movable assembly. The fixed member 141 has a through hole extending through its two opposite surfaces along a set direction, wherein the set direction is substantially parallel to the width direction of the tooling vehicle 100. The movable member 142 can pass through the through hole and move relative to the fixed member 141 along the set direction. In this embodiment of the present application, when the AGV chassis 200 is in the handling space of the tooling vehicle 100, the movable member 142 is inserted under the AGV chassis 200 through the through hole on the fixed member 141 to support the AGV chassis 200.

[0037] As a way to implement Figure 6 As shown, the lifting device 12 further includes a lifting chain 123. The guide assembly 121 and the moving assembly 122 are respectively provided with gears 124 that engage with the lifting chain 123. The driving assembly 13 drives the moving assembly 122 along the height direction through the transmission of the chain 123 and the gear 124.

[0038] As a way to implement Figure 7 As shown, a limiting mechanism 112 can also be provided at the bottom of the chassis 11. The limiting mechanism 112 is configured to be movable in the height direction. The limiting mechanism 112 includes a first state and a second state. In the first state, the AGV chassis 200 is in the handling space of the tooling vehicle 100. The AGV chassis 200 needs to be raised for maintenance work. The limiting mechanism 112 is extended and abuts against the ground to keep the tooling vehicle 100 stable, prevent the tooling vehicle 100 from sliding during the maintenance process, and improve safety. In the second state, when the maintenance work on the AGV chassis 200 is completed, the AGV chassis 200 is lowered and the limiting mechanism 112 is retracted and separated from the ground.

[0039] like Figure 7 As shown, as an implementation, the tool vehicle 100 further includes a control handle 15 , which is mounted on a side of the chassis 11 opposite to the opening 114 of the chassis 11 , so as to facilitate the operator to control the tool vehicle 100 .

[0040] According to the above description, the present application provides a tool vehicle 100, which is provided with a support component 14 to support the AGV chassis, and the drive component 13 provides power to drive the mobile component 122 to move, thereby driving the support component 14 to lift the AGV chassis off the ground, making it easier for maintenance personnel to carry out their work; and, by providing a self-locking mechanism, the height to which the AGV device is raised can be flexibly adjusted and the height can be fixed, thereby preventing the AGV device from abnormally falling due to damage to the drive component 13, thereby ensuring the safety of maintenance personnel; the use of the tool vehicle 100 reduces the work of manual handling, improves personnel work efficiency, reduces the risk of injury to staff, and saves labor costs.

[0041] Although the preferred embodiments of the present application have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the application as disclosed in the accompanying claims.
