Top car

The invention relates to a top car, in particular to a safe and easy to operate car.

According to the driving mechanism of the general top driving machine, the driving mechanism is pivotally connected to the active rod group, and the driving rod mechanism is pushed against the active rod group, thereby driving the active rod group and the driven rod group to be folded or unfolded, so that the jacking machine is raised or lowered. In order to prevent the drive mechanism from suddenly failing, causing the top car to crash rapidly and causing casualties, a hook is generally arranged under the active lever set for the normal arrangement of the tooth row of the base of the topping machine to prevent the top. The car crashes rapidly. When the top car wants to descend, it is necessary to operate a disengagement device to pull the hook off the tooth row, and the top car can be lowered.

However, the disengagement device of the conventional jacking machine is electrically operated (for example, the pivoting of the hook by the electromagnetic device) or the disengagement device is installed at the bottom of the jacking machine for the operator to step on the operation, and the electric operation is separated. The device is prone to failure. When the device is out of the device, the hook cannot be smoothly removed from the tooth row or can not be smoothly buckled on the tooth row, and the top car can not be lifted smoothly, or even the top car crashes rapidly and causes casualties. However, when the disengagement device is installed at the bottom of the top car, it is easy for the worker to be accidentally crushed by the jacking machine, and there is a defect that needs to be improved.

Therefore, it is necessary to provide a novel and progressive top car to solve the above problems.
