Description

Technical Field

[0001] The utility model relates to a group mould erecting machine, in particular to a walking device in the group mould erecting machine. Background Art

[0002] In the travel device of the existing group mold machine, the inner sides of the two tracks are both square steel tracks (square steel guide rails) or both are circular shaft tracks (circular shaft guide rails). However, due to the long length of the tracks, there may be a certain error in the length direction of the two tracks, and parallelism may not be guaranteed. At this time, if the inner sides of the two tracks use circular shaft tracks at the same time, the mobile section mold may derail, causing danger; and if the inner sides of the two tracks use square steel tracks at the same time, the parallelism of the two sides cannot be guaranteed, and slippage may occur, resulting in the two planes of the two adjacent movable molds (the mobile section mold and the standard vertebrae section mold, and between the standard vertebrae section molds) not being parallel. The main disadvantages of the travel device of the existing group mold machine are that the travel wheels are prone to radial movement, the installation and processing precision of the two tracks are high, and there is a risk of derailment of the mobile section mold. Summary of the invention

[0003] The purpose of the utility model is to provide a walking device in a group mold, which can ensure the position of the walking wheel in the roller mechanism and prevent the radial movement of the walking wheel, while reducing the installation and processing accuracy of the two tracks and reducing or eliminating the risk of derailment of the mobile section mold.

[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0005] A walking device in a group mold, comprising two parallel tracks, a template system, two racks installed on the two tracks and meshing with the power output gear of each movable segment mold in the template system, multiple pairs of roller mechanisms installed on the template system and two pairs of power mechanisms, each of the tracks can be divided into two sections, connected in the middle by a connecting plate. Each track has a track body and two main tracks located inside and outside the track body, the main tracks are also called wheel tracks, there are two track bodies in total, and there are four main tracks in total, the four main tracks are divided into a first main track and a second main track located inside the two track bodies and two third main tracks located outside the two track bodies, each movable segment mold in the template system is installed with four pairs of roller mechanisms and a pair of power mechanisms, that is, two pairs of roller mechanisms and one power mechanism are installed on both sides of the bottom of each movable segment mold in the template system, and the walking wheels (rollers) in each roller mechanism are limitedly supported by a corresponding main track (which can be one of the first main track, the second main track, and the third main track), and the technical solution is:

[0006] The first main track and the second main track located on the inner side of the two track bodies have different structures. One of the first main track and the second main track is a circular axis track (circular track), and the other is a square steel track (square track). The walking wheels in each of the roller mechanisms corresponding to the circular axis track have a groove that matches the circular axis track.

[0007] In the above technical scheme, the preferred technical scheme may be that each of the track bodies is formed by a transversely arranged upper plate, a transversely arranged lower plate, and a vertical plate arranged longitudinally between the upper plate and the lower plate, which are fixedly connected (may be welded), and each track body is an I-shaped structure composed of three plates, and each of the racks is respectively fixed to the bottom surface of the inner side of the upper plate of the corresponding track body, and the two racks are respectively installed on the two tracks (that is, the two racks are respectively installed on the bottom surface of the inner side of the upper plate of the two tracks), and the two racks are meshed with the power output gear of each movable section mold (the two racks cooperate with the gear in the movable section mold wheel group).

[0008] In the utility model, the first main track and the second main track located inside the two track bodies have different structures. One of the first main track and the second main track is a circular axis track (circular track), and the other is a square steel track (square track). The running wheel in each roller mechanism corresponding to the circular axis track has a groove that matches the circular axis track. In this way, the position of the running wheel (wheel) in the roller mechanism is ensured by the circular axis track to prevent the running wheel from running radially. The square steel track on the other side reduces the installation and processing accuracy of the two tracks, reduces or avoids the risk of derailment of the mobile section mold, and solves the problems of easy radial running of the running wheel, high requirements for installation and processing accuracy of the two tracks, and the risk of derailment of the mobile section mold. According to the test, compared with the related art, after adopting the running device in the group mold of the utility model, the service life of the group mold machine is extended by more than 25%.
