At present, when a rolled steel rolling guide is maintained, the guide needs to be erected and laid down for 2 times, when the guide is erected, the guide is erected manually and directly by hands or by using a crowbar, the weight of the guide needing to be maintained is 30 Kg-150 Kg, the labor intensity is high when an operator erects and lays down the guide, and potential safety hazards of smashing and bruising exist when the guide is disassembled after the guide is erected by hands or the crowbar. Therefore, in order to solve the above problems, a guide turning trolley device is needed to be designed.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a lead and defend upset dolly device, simple structure through worm gear transmission machinery turning device, will lead and defend overturning, convenient operation, labour saving and time saving.
The utility model discloses a guide overturning trolley device, which comprises a guide and an overturning device for overturning the guide; the turning device comprises a main trolley, a rotating mechanism and a clamping mechanism; the rotating mechanism and the clamping mechanism are respectively arranged on the main body trolley;
the main trolley comprises a chassis, a main supporting arm and an auxiliary bracket which are vertically fixed on two sides of the chassis, and universal wheels which are arranged at four corners of the bottom of the chassis; the rotating mechanism consists of a worm, a worm wheel and a worm hand wheel; the worm is arranged in the main supporting arm in a penetrating way; the worm hand wheel is arranged at the front end of the worm wheel; the worm wheel is arranged in the main supporting arm and is in transmission meshing with the worm; the clamping mechanism is a chuck; the chuck is arranged at the front end of a transmission shaft of the worm gear; the guide is fixed on the chuck, after the guide is clamped, the worm hand wheel is rotated to drive the worm wheel to rotate, and the chuck is driven to rotate by the worm wheel, so that the guide is turned over, and the guide is disassembled, assembled and maintained.
Furthermore, a supporting round bar is arranged between the chuck and the auxiliary bracket; one end of the supporting round rod is movably connected with the auxiliary support, the other end of the supporting round rod penetrates through the guide and is inserted into the round pipe at the center of the chuck, in order to ensure that the turnover-shaped maintenance operation is carried out more safely and reliably, the supporting round rod penetrates through the guide from the auxiliary support at the front end and is directly inserted into the round pipe at the center of the chuck to form a support, and the chuck is prevented from falling off due to the fact that the guide is not clamped tightly.
Still further, the end of the auxiliary bracket is provided with a through hole for installing and supporting the round rod.
