Description

Technical Field

[0001] The utility model belongs to the technical field of roller replacement for leveling machines, and particularly relates to a roller replacement vehicle device for a segmented leveling machine. Background Art

[0002] The roller type sheet metal leveling machine with roller changing function has multiple sets of roller systems of different specifications. Each set of roller systems corresponds to its own dedicated gear distribution box. The traditional roller changing structure installs the roller system and the gear distribution box on the same roller changing car. The roller changing car is equipped with a wheel system for roller system replacement. During the roller changing process, the wheel system walks on the installation platform. After the roller changing action is completed, the wheel system enters the groove set on the installation platform. The bottom surface of the roller changing car contacts the installation platform. Therefore, the height of the roller system during the roller changing process is different from that during the use process. Since the roller changing car is a rigid structure, the relative height of the roller system and the gear distribution box cannot be changed during the entire roller changing process. In order to shorten the replacement time, the input shaft of the gear distribution box is mostly connected by a spline shaft connected to the spline sleeve of the power system. In order to achieve the continuity of the roller changing process, it is necessary to first move the roller system to the working position and height, and then move the power system to complete the process of spline connection with the roller system gear distribution box. Therefore, the power system of the roller changing leveling machine with this structure must be designed as a mobile structure, which has high design cost and poor stability in use of the power system.

[0006] The roller system roller changing vehicle and the gear distribution box roller changing vehicle are placed on the installation platform, the roller system roller changing wheels are installed at the bottom of the roller system roller changing vehicle, and the gear distribution box roller changing wheels are installed at the bottom of the gear distribution box roller changing vehicle.

[0007] The installation platform is provided with a roller system groove and a gear distribution box groove, and a lifting platform is provided in the roller system groove, and the lifting platform is driven by a lifting cylinder.

[0008] The bottom of the gear distribution box roll-changing vehicle is provided with plate-type self-lubricating bearings located on both sides of the gear distribution box roll-changing wheels.

[0009] A spline shaft is installed on the side of the gear distribution box, and the spline shaft is connected to a spline sleeve installed on the side of the power system.

[0010] The beneficial effects of the utility model are as follows: the roll system and the gear distribution box are provided with separate roll-changing vehicles, which are connected by a flexible hinged structure, and the height of the roll system relative to the gear distribution box is variable. The bottom surface of the roll-changing vehicle of the gear distribution box is equipped with a plate-type self-lubricating bearing, and the roll-changing vehicle of the gear distribution box enters the working connection height in advance, and completes the connection process between the spline shaft and the spline sleeve through sliding friction. In this way, the position of the power system of the leveling machine can be fixed, thereby ensuring the stability of the operation of the transmission system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The attached drawing is a specific embodiment of the utility model. The embodiment includes a roller system roller changing vehicle 5, a gear distribution box roller changing vehicle 6, a flexible connection structure and a wheel system. The roller system roller changing vehicle 5 is equipped with multiple sets of roller system roller changing wheels 12, which are used to move on the installation platform 11. After the roller system 2 moves to the working position, a lifting platform 16 is provided at the corresponding position of its roller system roller changing wheels 12. The lifting platform 16 is installed in the roller system groove 14 on the installation platform 11, and the lifting cylinder 17 is fixed to the installation platform 11 by screws. The piston rod of the lifting cylinder 17 is connected to the lifting platform 16 by threads, and the lifting platform 16 is controlled by the lifting cylinder 17. The position of the lifting platform 16 is lowered until the bottom surface of the roller system roller changing vehicle 5 contacts the installation platform 11, and the roller system 2 reaches the working height.

[0021] The gear distribution box roll-changing vehicle 6 is equipped with multiple groups of gear distribution box roll-changing wheels 13, and plate-type self-lubricating bearings 18 are installed on the bottom surface and arranged on both sides of the gear distribution box roll-changing wheels 13. The gear distribution box roll-changing vehicle 6 moves by the gear distribution box roll-changing wheels 13 at the starting position. When the gear distribution box 4 moves to the position where the spline shaft 19 is close to the spline sleeve 21 of the power system 20, its gear distribution box roll-changing wheels 13 enter the gear distribution box groove 15 set at the corresponding installation platform 11. The gear distribution box roll-changing vehicle 6 reaches the working height (that is, the height of the spline shaft 19 reaches the installation height of the spline sleeve 21), and the plate-type self-lubricating bearings 18 contact the installation platform 11. The movement mode of the gear distribution box roll-changing vehicle 6 changes from rolling by the gear distribution box roll-changing wheels 13 to sliding movement by the plate-type self-lubricating bearings 18. When the spline shaft 19 and the spline sleeve 21 are installed and matched, the gear distribution box roll-changing vehicle 6 reaches the working position.

[0022] The first articulated seat 7 is fixed to the roller system roll changing vehicle 5 by screws, and the second articulated seat 8 is fixed to the gear distribution box roll changing vehicle 6 by screws. The first articulated seat 7 and the second articulated seat 8 are connected by an articulated shaft 10. The holes through which the articulated shaft 10 passes on the first articulated seat 7 and the second articulated seat 8 are both vertical waist holes 9, and the relative height of the first articulated seat 7 and the second articulated seat 8 has a certain adjustment amount. The roller system roll changing vehicle 5 and the gear distribution box roll changing vehicle 6 are connected by a flexible connection structure, and the relative height is variable.
