SUMMARY

[0003] The utility model solves the technical problem that the pressure maintaining tool cannot adapt to the installation of multiple AGV trolleys.

[0004] Based on the technical problems in the background art, the utility model provides an adjustable pressure maintaining tool, which comprises a first group of frame bodies and a second group of frame bodies installed on both sides of the trolley respectively, a first group of frame bodies is installed with an extrusion device that can be turned over to the second group of frame bodies, the extrusion device can rotate along the longitudinal axis relative to the first group of frame bodies and shorten the linear interval between the first group of frame bodies and the second group of frame bodies.

[0005] In the above-mentioned scheme, the installation of the trolley with different widths is adapted by shortening the interval between the two groups of frame bodies, the extrusion device in the application can be deformed through the quadrilateral and cope with the installation of different intervals between the two groups of frame bodies, and can be used for the installation and use of multiple trolleys.

[0006] Preferably, the first group of frame bodies comprises a first supporting rod that can be adjusted in height and a first cross bar connected with the first supporting rod, both ends of the first cross bar are supported by the first supporting rod and keep the first cross bar horizontal, and the middle part of the first cross bar is provided with a first longitudinal slot.

[0007] In the above-mentioned scheme, the first supporting rod is used for adjusting the height of the first group of frame bodies as a whole, and the height of the first cross bar can be adjusted, the height adjustment can correspond to the testing and use of batteries with different heights, and the application range of the battery can be improved.

[0008] Preferably, the second group of frame bodies comprises a second supporting rod that can be adjusted in height and a second cross bar, the middle part of the second cross bar is provided with a second longitudinal slot, and the middle part of the second longitudinal slot passes through a hand screw bolt to fix the top end of the second supporting rod.

[0009] In the above scheme, the second support rod is used to match the first support rod for lifting and lowering. After the two sets of support plates are kept at the same height, the extrusion device can be kept horizontal after being fixed and can be installed close to the upper surface of the battery. The hand-tightening bolt is used to quickly connect the second crossbar and the second support rod, which is convenient for personnel to use.

[0010] Preferably, the extrusion device includes a sliding member, a hinge member, and a pressure plate. Both ends of the pressure plate are rotatably connected to hinge members, and the axis of the rotation shaft is parallel to the ground. Each hinge member is rotatably connected to a sliding member, and the axis of rotation is perpendicular to the ground. The sliding members at both ends of the pressure plate are respectively fixed in the first strip groove and the second strip groove.

[0011] In the above scheme, the sliding component and the hinge component enable the pressure plate to have a flipping effect. The combination of the two components enables the pressure plate to rotate in two directions. The combination of the two sets of sliding components and hinge components enables the two parallel pressure plates to form a parallelogram deformation effect and can also flip relative to the first crossbar.

[0012] Preferably, the first crossbar and the second crossbar are parallel to each other, and the sliding parts at both ends of the two sets of extrusion devices are installed corresponding to the first strip groove and the second strip groove respectively, so that the pressure plates of the two sets of extrusion devices are parallel to each other.

[0014] In the above scheme, the platform can directly compress the upper surface of the battery, and in this application, it mainly provides an installation position for the extrusion plate.

[0015] Preferably, an extrusion plate is provided below the platform, and a drive mechanism connected to the extrusion plate is provided on the platform.

[0016] In the above scheme, the driving mechanism is a cylinder. When there is a certain gap between the extrusion plate and the upper surface of the battery, the extrusion plate cannot effectively extrude the upper part of the battery. The driving mechanism can change the gap between the extrusion plate and the upper surface of the battery and extrude the battery.

By deforming the parallelogram, it can adapt to the width of trolleys of different sizes, increasing the range of trolleys it can accommodate and improving convenience. Attached Figure Description
