Technical Field

[0001] The invention relates to the technical field of mechanical parking equipment, in particular to a vehicle pulling device using a hook for a carrier. Background Art

[0002] The transporter for parking equipment is one of the core components of the intelligent multi-story parking garage. It is responsible for the precise transport and parking of vehicles inside the garage, greatly improving parking efficiency and space utilization. The transporter for parking equipment integrates many cutting-edge technologies. Through the comprehensive application of these technologies, it realizes high automation and intelligence of vehicle transportation, greatly reduces manual intervention, and improves the intelligent management level and user experience of the multi-story parking garage.

[0003] The car retrieval device is one of the core components of the transporter. Its principles and parameters directly affect the performance of the transporter and even the quality of the entire three-dimensional parking garage.

[0004] At present, some car retrieval devices of stereo garage transporters adopt clamping or comb-tooth lifting to retrieve the car. The clamping device needs to hold the tires of the vehicle from both sides, which requires high power, complex structure and high failure rate. The comb-tooth lifting device needs lifting space, so it needs a structural support, which occupies a large space and the lifting speed of the lifting device is slow, resulting in a slow retrieval speed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a hook-pulling vehicle retrieval device for a transporter, which has the advantages of fast vehicle retrieval speed and low failure rate, and solves the problem that the existing clamping vehicle retrieval device needs to hold the vehicle tires from both sides, requires large power, has a complex structure and has a high failure rate; and the comb-tooth lifting vehicle retrieval device requires a lifting space, so a structural support is required, which occupies a large space and the lifting speed of the lifting vehicle retrieval device is slow, resulting in a slow vehicle retrieval speed.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a hook-pulling vehicle device for a carrier, comprising a movable frame, on which a hook-pulling vehicle mechanism is provided;

[0007] The hook-pulling vehicle mechanism includes a fixed frame fixedly mounted on the surface of one side of the movable frame, a reduction motor and an electric push rod are fixedly mounted on the surface of the fixed frame, a shaft coupling is fixedly mounted on the output end of the reduction motor, a lead screw is fixedly mounted on the end of the shaft coupling away from the reduction motor, a lead screw nut is threadedly connected to the surface of the lead screw, a connecting rod is hinged on the surface of the lead screw nut, a swing arm is rotatably mounted on the surface of the movable frame, an end of the connecting rod away from the lead screw nut is hinged to one end of the swing arm, a guide wheel groove is opened on the surface of the fixed frame, and a guide wheel is rotatably mounted inside the guide wheel groove.

[0008] Furthermore, two support wheels are rotatably mounted on the surface of the movable frame, the two support wheels are distributed on both sides of the movable frame, and the support wheels are away from the fixed frame.

[0009] Furthermore, the number of the connecting rods and the number of the swing arms are both two, the two connecting rods are symmetrically distributed on the surface of the screw nut, and the two swing arms are symmetrically distributed on both sides of the screw nut and the screw.

[0010] Furthermore, the number of the guide wheel grooves is two, and the two guide wheel grooves are symmetrically distributed on the surface of the fixed frame, and the number of the guide wheels matches the number of the guide wheel grooves.

[0011] Furthermore, the number of the electric push rods is two, and the two electric push rods are distributed on a side surface of the fixed frame away from the movable frame.

[0012] Furthermore, the end of the lead screw away from the shaft coupling is rotationally connected to the movable frame.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The carrier uses a hook to pull the vehicle device. The reduction motor, shaft coupling and lead screw can drive the horizontal movement of the lead screw nut. The horizontal movement of the lead screw nut can drive the rotation of the connecting rod and the swing arm, so that the swing arm can hook the vehicle tire. The vehicle can be pulled by the electric push rod. The hook action is realized by the lead screw drive and the connecting rod drive. It has a simple structure and reliable operation. The pulling action is realized by the electric push rod and the guide groove wheel. The principle is practical, stable and reliable.

[0015] 2. The transporter uses a hook-pull vehicle picking device. The hooking and pulling actions are both achieved through the single arm in the action force and the reaction force, which reduces the power loss of the reaction force by half, so that under the same conditions, the vehicle picking force is doubled. Since the vehicle picking force is increased, the vehicle picking speed is correspondingly increased, thereby greatly improving the vehicle picking speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Two supporting wheels 2 are rotatably mounted on the surface of the movable frame 1 . The two supporting wheels 2 are distributed on both sides of the movable frame 1 , and the supporting wheels 2 are away from the fixed frame 11 .

[0022] It should be noted that the movable frame 1 in this embodiment is the main structural component of the present invention, which is welded with steel plates and has strong rigidity.

[0023] The support wheel 2 is a ground support component in the invention, which is installed at the front end of the device, one on each side, and can roll on the ground to support the weight.

[0024] The lead screw nut 3 is a power transmission component in the present invention, which cooperates with the lead screw 6 and can perform horizontal displacement on the lead screw 6.

[0025] The connecting rod 4 is a connecting component in the present invention, one end of which is hinged to the screw nut 3 and the other end of which is hinged to the swing arm 5, so that the horizontal movement of the screw nut 3 can be converted into the rotation of the swing arm 5.

[0026] The swing arm 5 is an actuator in the present invention, which can rotate under the action of the connecting rod 4, and contact with the automobile tire after rotation, giving the tire a horizontal force, thereby causing the automobile tire to move.

[0027] The lead screw 6 is a power transmission component in the present invention, which cooperates with the lead screw nut 3 to convert the rotation into the horizontal displacement of the lead screw nut 3.

[0028] The coupling 7 is a connecting component between the reduction motor 8 and the lead screw 6 , which can realize the connection between the reduction motor 8 and the lead screw 6 and transmit torque, thereby transmitting the rotation of the reduction motor 8 to the lead screw 6 .

[0032] The working principle of the above embodiment is:

[0033] When in use, the device is moved to the bottom of the vehicle. After the front end of the device contacts the vehicle tire, the reduction motor 8 is powered on and starts to rotate, and the rotational torque is transmitted to the lead screw 6 through the coupling 7. The lead screw 6 rotates, causing the lead screw nut 3 mounted on the lead screw 6 to produce a horizontal displacement. The horizontal displacement of the lead screw nut 3 drives the two swing arms 5 to achieve a ninety-degree horizontal rotation in opposite directions through the two connecting rods 4 hinged at both ends, so that the swing arms 5 hook the two tires of the car, and then the vehicle tires can be hooked. When the swing arms 5 hook the car tires, at this time, the two electric push rods 10 start to be powered on and run at the same time, so that the overall length of the electric push rods 10 is shortened, driving the movable bracket 1 to move horizontally under the guidance of the guide wheel 9, and the swing rod 5 mounted on the movable bracket 1 moves horizontally synchronously with the movable bracket 1, so that the swing rod 5 applies a horizontal force to the car tire, driving the car tire to move horizontally, and then the car tire can be pulled.
