A nut screw type car carrier

Abstract

The invention discloses a nut screw type automobile transporting device which comprises a transporting vehicle, a lifting bracket and an unfolding mechanism. The lifting bracket is arranged on the upper side of the transporting vehicle; the unfolding mechanism is arranged on the upper side of the lifting bracket; the lifting bracket comprises a front upper frame and a rear upper frame; the front upper frame and the rear upper frame are correspondingly provided with jacking mechanisms for jacking; each jacking mechanism comprises a jacking motor, a jacking driving gear component, a chain, nut screws and jacking driven chain wheels; output ends of the jacking motors are in transmission connection with the jacking driving gear components; the jacking driving gear components are in transmission connection with the jacking driven chain wheels by means of the chain; and the jacking driven chain wheels are in transmission connection with input ends of the screw nuts. An output force of the chain is greatly reduced, the problem of easy damage of the chain under large load at long transportation distance is avoided, and the reliability of the transporting device is improved; and a plurality of unfolding driven gear components are driven at the same height by a single rack, so that the problem that the overall thickness of the transporting device is increased is further avoided.

Description

technical field [0001] The invention relates to the field of mechanical parking equipment, in particular to a nut screw type vehicle carrier. Background technique [0002] With the application of parking equipment more and more widely, land resources in cities are scarce, and the automation of newly built parking equipment is getting higher and higher. As the core component of parking equipment, the requirements for reliability, safety and efficiency of automobile carriers are becoming higher and higher. come higher. [0003] The jacking device of the existing car carrier is generally driven by the mode of motor-driving gear-chain-driven gear-cam. The structure of the cam is simple, and it is also suitable for short-distance jacking of the car carrier. The larger equivalent friction angle leads to larger total output torque required for lifting. However, due to the larger equivalent friction angle of the cam when it is lifted, the total output torque required for lifting is...

Problems solved by technology

[0003] The jacking device of the existing car carrier generally adopts the mode transmission of motor-driving gear-chain-driven gear-cam. The structure of the cam is simple, and it is also suitable for short-distance jacking of the car carrier. The larger equivalent friction angle leads to larger total output torque required for lifting. However, due to the larger equivalent friction angle of the cam when it is lifted, the total output torque required for lifting is also larger, thus The large load under the long transmission distance of the chain will easily cause the chain to be damaged, thus affecting the reliability of the equipment

[0004] In addition, the unfolding mechanism of the existing vehicle carrier is generally driven in the form of motor-driving gear-chain-driven gear-executing element. When using a single motor to drive multiple driven gears, it needs to be provided with multiple The drive gear arranged coaxially increases the overall thickness of the carrier and affects the performance

At the same time, the reliability and maintainability of the chain transmission method are also poor, which is not conducive to the normal operation of the car carrier
