[0019] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positions of components in relation to the directions shown in the accompanying drawings or in relation to the vertical, perpendicular, or gravitational directions.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] The present invention first provides a leveling device for a boom cover plate.

[0022] In one implementation, refer to the appendix. Figure 1 As shown, the boom cover plate leveling device includes a leveling drive device 1, a detection component 2, and a controller. The leveling drive device 1 can support the boom cover plate and drive the boom cover plate to rotate circumferentially. The detection component 2 is used to detect the horizontal height of both ends of the boom cover plate. The controller is used to control the leveling drive device 1 to drive the boom cover plate to rotate circumferentially according to the detection result of the detection component 2, so that both ends of the boom cover plate are at the same horizontal height.

[0023] Understandably, in the boom cover plate leveling device of this embodiment, the controller can control the leveling drive device 1 to drive the boom cover plate to rotate circumferentially according to the detection results of the detection component, so that the two ends of the boom cover plate are at the same horizontal height. With this setting, the boom cover plate is automatically leveled without manual operation, which is easy to operate, efficient, accurate, and safe.

[0024] In one embodiment, the leveling drive device 1 includes a support platform 11 and a roller mechanism 12. The top surface of the support platform 11 is recessed with a positioning groove that can accommodate the boom cover plate. The positioning groove extends longitudinally along the top surface of the support platform 11. The roller mechanism 12 includes a plurality of support rollers 121 and a plurality of rotation drive members. The plurality of support rollers 121 are arranged circumferentially on the inner wall of the positioning groove to form an arc-shaped support surface for supporting the outer arc surface of the boom cover plate. The axial direction of each support roller 121 is consistent with the extension direction of the positioning groove. The plurality of rotation drive members are electrically connected to the controller and are used to drive the plurality of support rollers 121 to rotate according to the control signal of the controller.

[0025] Understandably, in practical applications, the boom cover plate is accommodated in the positioning groove and its outer arc surface is supported on the arc-shaped support surface formed by multiple support rollers 121. With this configuration, multiple rotation drive components drive multiple support rollers 121 to rotate, and the rotation of multiple support rollers 121 can drive the boom cover plate to rotate circumferentially. The rotation direction, speed and rotation time of the support rollers 121 are controlled by the controller, so that the boom cover plate can be precisely rotated until both ends are at the same horizontal height.

[0026] Specifically, the rotation drive component can be a drive motor.

[0027] In one embodiment, the roller mechanism 12 further includes a plurality of radial drive members, which are used to drive a plurality of support rollers 121 to move radially along the positioning groove to adjust the curvature of the arc-shaped support surface. With this configuration, the curvature of the arc-shaped support surface can be adjusted according to the specifications of the boom cover plate to be leveled. In this way, the boom cover plate leveling device can be applied to the leveling of boom cover plates of various different specifications.

[0028] Furthermore, the boom cover plate leveling device also includes an information reader, which is used to obtain the specification information of the boom cover plate. The controller is also used to control multiple radial drive components to drive multiple support rollers 121 to move radially along the positioning groove according to the specification information obtained by the information reader, so as to adjust the curvature of the arc support surface and make the arc support surface fit the outer arc surface of the boom cover plate.

[0029] In practical applications, QR codes or barcodes can be set on the boom cover plate. Information reading devices can directly read the codes to obtain the specification information of the boom cover plate. Specifically, the information reading device can be a code reader, such as an RFID code reader or an infrared code reader.

[0030] In one embodiment, the roller mechanism 12 includes a plurality of mounting seats, each of which is movably embedded in the inner wall of the positioning groove along the radial direction of the positioning groove. A plurality of rollers are rotatably mounted on the top ends of the plurality of mounting seats extending out of the inner wall of the positioning groove. A plurality of radial drive members are respectively connected to the plurality of mounting seats for driving the plurality of mounting seats to move radially along the positioning groove. In this configuration, the radial drive members drive the mounting seats to move radially along the positioning groove, thereby driving the rollers to move radially along the positioning groove.

[0031] Specifically, the radial drive component can be a hydraulic cylinder, a pneumatic cylinder, or the like.

[0032] In one embodiment, the positioning groove is U-shaped, and the multiple support rollers 121 are divided into two groups. The two groups of support rollers 121 are arranged symmetrically with respect to the longitudinal symmetrical surface of the positioning groove. This arrangement enables the multiple support rollers 121 to support and drive the boom cover plate to rotate more stably.

[0033] In one embodiment, the detection component 2 includes a first detection element 21 and a second detection element 22, both of which are disposed on the top surface of the support platform 11 and respectively arranged on both sides of the positioning groove.

[0034] In practical applications, after the two ends of the boom cover plate are supported on multiple support rollers 121, the two ends will extend out of the slot of the positioning groove. At this time, the first detection element 21 and the second detection element 22 arranged on the lateral sides of the positioning groove can respectively detect the two ends of the boom cover plate.

[0035] Specifically, both the first detection element 21 and the second detection element 22 are vision sensors.

[0036] In one embodiment, the leveling drive device 1 includes a plurality of roller mechanisms 12, which are arranged at intervals along the extension direction of the positioning groove. This arrangement makes the boom cover plate leveling device suitable for leveling boom covers of different lengths.

[0037] This invention also proposes a boom production line, which includes the boom cover plate leveling device described above. The specific structure of the boom cover plate leveling device is as described in the above embodiments. Since this boom production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.
