Description
Technical Field
The utility model relates to the technical field of rescue transportation equipment, in particular to a wheel track adjustable rescue cart.
Background
When rescue is needed after large-scale natural disasters such as earthquake or debris flow happen, the road is not communicated in most cases due to complex rescue scenes. Rescue workers need to enter disaster areas for rescue through long-distance trekking. After a large number of rescue appliances carried by rescuers enter a disaster area through long-distance running waves, physical strength often drops greatly, and therefore rescue is possibly affected. Therefore, it is necessary to transport the materials using a cart. The existing cart is divided into a double-wheel cart or a single-wheel cart, although the single-wheel cart has wide adaptability, the stability of the single-wheel cart is poor, and the stability of the double-wheel cart is good, but the adaptability of the double-wheel cart is poor.

The utility model aims to provide a wheel track adjustable rescue trolley aiming at the defects of the prior art, and the purpose of adapting to road conditions by adjusting the wheel track is achieved.
The utility model provides a wheel track adjustable rescue cart, which comprises a cart plate; the method is characterized in that: the lower end of the turning plate is connected with the power mechanism through an adjusting mechanism, the adjusting mechanism comprises a motor, a bidirectional screw rod and a fixed seat, the fixed seat is mounted at the lower end of the turning plate, a chute is arranged on the fixed seat, the bidirectional screw rod is mounted in the chute of the fixed seat, two ends of the bidirectional screw rod are respectively in rotating fit with the inner wall of the chute, and the middle position of the bidirectional screw rod is connected with a motor shaft of the motor through a commutator; the power mechanism comprises a motor, a wheel and a sliding frame, the motor is connected with the wheel through a commutator, the sliding frame is connected with the commutator and the motor, a threaded through hole is formed in the upper end of the sliding frame, the upper end of the sliding frame is placed in a sliding groove of the fixing seat, two sections of threads of the bidirectional screw rod are matched with the threaded through hole of the sliding frame respectively, and a battery is installed at the lower end of the turning plate.
One end of the vehicle plate is connected with the two handrails, and the other end of the vehicle plate is vertically connected with the baffle.
The battery bin is sleeved outside the battery.
The handrail is provided with electronic switches, and each electronic switch is respectively connected with the motor of the power mechanism, the motor of the adjusting mechanism and the battery through circuits.
Compared with the prior art, the utility model has the following outstanding beneficial effects:
1. the distance between the two wheels can be adjusted through the adjusting mechanism according to the actual road condition, so that the actual road condition is compounded;
2. the two sides of the vehicle plate are respectively provided with the power mechanism, and the two power mechanisms are respectively controlled by the electronic switch, so that the steering flexibility can be ensured under the condition of ensuring the stable running of the vehicle body.
