Description

A three-dimensional garage vehicle handling device

technical field

The invention belongs to the technical field of load-carrying machinery, and in particular relates to a three-dimensional garage picking-up equipment.

Background technique

With the rapid increase of the number of private cars in the city, the three-dimensional parking garage will become an important way to solve the difficult problem of urban parking. At present, there are three main types of car carriers in the three-dimensional garage: the car-carrying plate type, the comb-tooth type and the clamping tire type.

The car-carrying plate type carrier is only suitable for the vertical lifting garage of the lower floor. When the number of garage floors is too high, the time for accessing the car is too long, so it is not suitable for promotion.

The comb-toothed carrier has strict requirements on the main structure of the garage, and the parking space must be in the shape of a comb, which not only increases the cost of design and manufacture, but also reduces the stability and safety factor of the parking space.

The clamping tire type carrier can directly drill under the vehicle, clamp the wheel and carry the vehicle, which is more efficient. Compared with the comb type, the structure is simple and the installation is convenient. It is an ideal carrier in the three-dimensional garage.

According to retrieval, the existing garage transporter, such as the Chinese patent No. 200910018524.7 titled "Clamping Tire Type Three-dimensional Garage Car Transporter", the clamping mechanism of this patent adopts a symmetrical arrangement, and the clamping motor drives the driving gear to drive The rotation of the shaft gear and the intermediate wheel has high requirements for machining and installation accuracy, which increases the difficulty for the final realization.

Another example is the Chinese patent No. 201410172718.3 titled "Intelligent Carrier for Three-dimensional Garage". This patent uses guide grooves and steering racks to realize the clamping function. The structure is complex and there is no locking mechanism. When an accident occurs, it cannot guarantee to continue Clamping the wheel can easily lead to accidents.

In view of the above situation, it is necessary to develop a simple in structure, safe and reliable novel three-dimensional garage car carrier.

Contents of the invention

The purpose of the present invention is to provide a three-dimensional garage vehicle handling device, which can effectively realize the clamping and fixing and longitudinal and lateral movement when the three-dimensional garage takes in the vehicle.

The object of the present invention is achieved through the following technical proposal: the proposal is innovatively designed, and uses the combination of steel wheels and light rails to realize stable walking.

The treads of the traveling wheels cooperate with the tracks of the underframe.

The present invention realizes the function of the clamping arm to clamp the wheel through the use of the four-bar mechanism, utilizes the dead point position of the four-bar mechanism to keep the clamped state after the wheel is clamped, and at the same time, through the cooperation of the ratchet and pawl, the clamping arm is further ensured. The clamping state of the holding arm can avoid property loss caused by the loosening of the clamping arm.

Both the bottom self-propelled mechanism and the wheel clamping mechanism of the present invention are independently driven by four wheels, so as to prevent the carrier from stopping on the way due to the traction motor or other problems, which will affect the subsequent work of accessing the car.

Bottom self-propelled mechanism, including the bottom two-way travel motor, chassis and track, the chassis is provided with two track installation grooves, the installation grooves are two parallel and symmetrical linear grooves, located above the chassis, parallel to the length of the chassis direction;

Set at the bottom of the bottom frame, there are four driving wheels with power used to drag the bottom frame to move. Each wheel includes a bidirectional motor, a driving synchronous wheel, a driven synchronous wheel, and a synchronous belt. The bidirectional motor passes through the driving synchronous wheel, the slave The dynamic synchronous wheel and the synchronous belt drive the wheel, and drive the bottom frame to move selectively in two directions along the direction perpendicular to the track installation groove;

Two rails arranged above the rail installation groove and used to carry the traveling direction of the wheel clamping mechanism;

There are two sets of wheel clamping mechanisms located above the two rails. Each wheel clamping mechanism includes a clamping mechanism, four bidirectional travel wheels, a chassis, four pawls, four electromagnets and four springs. Each chassis It is kept parallel to the track plane by four bi-directional traveling wheels.

The four two-way traveling wheels respectively arranged under the two chassis include traveling motor, shaft coupling, electromagnetic clutch, first and second driving sprockets, first and second driven sprockets, and chains. Shaft and electromagnetic clutch, the first and second driving sprockets drive the first and second driven sprockets and travel wheels to rotate through chain transmission, and drive the chassis to move in a direction parallel to the track relative to the chassis, and the electromagnetic clutch can control Power transmission and cut-off of the travel motor,

Four springs respectively arranged on the chassis and the other ends of which are installed on the pawl;

The four pawls respectively arranged on the chassis and used to lock the first and second clamping link joints are pressed against the ratchet teeth of the first and second clamping link joints by springs;

The four electromagnets respectively arranged on the chassis and located near each pawl control the pawl to leave or press the clamping link joint through the power on and off of the electromagnet, and then control the rotation of the clamping arm.

Work process and principle of the present invention are:

Storage process:

When the car drives to the bottom self-propelled mechanism of the three-dimensional garage vehicle handling device, the clamping motors on the two wheel clamping mechanisms start to rotate respectively, driving the first and second driving sprockets to rotate, and driving the first and second driving sprockets through the chain. When the driven sprocket rotates, the first and second clamping link joints on the first, second and second driven sprockets start to rotate, driving the clamping arm to rotate. When the roller on the clamping arm touches the wheel, the roller It rolls under the frictional force with the wheels, and clamps the front and rear four wheels respectively under the action of the two clamping arms and the rollers on them to lift the vehicle body. At this time, the ratchet automatically locks one end of the ratchet teeth of the first and second clamping link joints to ensure that the wheel is always kept above the wheel clamping mechanism during transportation. At the same time, the clamping mechanism is essentially a four-bar mechanism, and now the clamping mechanism is at the dead point.

After the wheel clamping mechanism clamps the car wheel, the four bottom two-way traveling wheels under the bottom self-propelled mechanism can start to work, and the two-way motor drives the active synchronous wheel, the synchronous belt and the driven synchronous wheel to rotate, so that the bottom wheel starts to rotate, driving the bottom The self-propelled mechanism and the wheel clamping mechanism on it move left and right along the track direction on the track.

When the bottom self-propelled mechanism traversed to the required transverse position left and right, the bottom two-way running mechanism stopped working, and now the four two-way running wheels that were respectively positioned at the bottom of the two wheel clamping mechanisms started to work. The walking motor starts to rotate, and drives the first and second driving sprockets to start to rotate through the coupling and the electromagnetic clutch, and the first and second driving sprockets drive the first and second driven sprockets to start to rotate through the transmission of the chain. The first and second driven sprocket wheels are installed on the same shaft and the running wheels start to rotate, driving the wheel clamping mechanism to advance along the track direction on the two tracks of the bottom self-propelled mechanism and enter the parking space track.

When the wheel clamping mechanism moves to a suitable position on the parking track, the travel motor stops working, and at this time, the electromagnet near the pawl on the chassis starts to work, attracting the pawl to leave the ratchet at the end of the first and second clamping link joints At the same time, the clamping motor starts to work in the opposite direction, driving the clamping arms to rotate back to each other in pairs, the wheels touch the parking space plane, the car stops on the parking space, the wheel clamping self-propelled travel motor reverses, and the clamping arms return to the bottom to move on their own appropriate location on the organization.

Pick up process:

When the bottom self-propelled mechanism moves left and right to the required horizontal position, the bottom self-propelled mechanism stops working. At this time, the travel motor of the wheel clamping mechanism works to drive the wheel clamping mechanism to move to the bottom of the car along the track on the bottom self-propelled mechanism and the parking space track. After the proper position, the walking motor stops working. At this time, the clamping motor starts to work. After driving the clamping arm to clamp the wheel, the clamping motor stops working. At this time, the car leaves the parking space, and then the walking motor reverses to drive the wheel clamping mechanism along the track. After returning to the appropriate position on the bottom self-propelled mechanism, the walking motor stops working. At this time, the bidirectional motor of the bottom self-propelled mechanism starts to work. After driving the bottom self-propelled mechanism to move laterally to a suitable position, the bidirectional motor stops working. claw, the clamping motor reverses, the clamping arm releases the wheel, the vehicle is placed on the bottom self-propelled mechanism, and the car can drive away from the bottom self-propelled mechanism.
