Problems solved by technology

[0003] Although, our company discloses telescopic tire clamping device in CN 206562812 U, it adopts four pairs of telescopic tire clamping devices, and each pair of tire clamping devices includes two respectively that can move along the vehicle body length direction and along the vehicle body. The structure of the mobile telescopic arm that expands and contracts in the width direction is relatively complicated, and all of them adopt a telescopic cantilever structure. This structure needs to have high structural strength, and its cost is relatively high.

Embodiment 1

[0046] like Figure 1-12 As shown, the multi-link tire clamping device mounted on the AGV trolley includes two sets of symmetrically arranged open-close tire clamp mechanisms for synchronous clamping and lifting of the four wheels of the car; each set of open-close tire clamps Mechanisms all include a ball screw mechanism 2 for providing driving force, and the ball screw mechanism 2 is fitted with a first nut sleeve structure 3 and a second nut sleeve structure 4 through screw transmission; the first nut sleeve structure 3 And the two ends of the second nut sleeve structure 4 are respectively hinged with a multi-linkage mechanism 5 for realizing the opening and closing action, and each execution end of the multi-linkage mechanism 5 is connected with a multi-linkage mechanism for clamping with the outer wall of the automobile tire. The clamping arm structure 6. By adopting the multi-link tire clamping device with the above structure, it can be used in the intelligent garage, t...

Embodiment 2

[0056] The operation method of any one of the multi-link tire clamping devices mounted on the AGV trolley is characterized in that it comprises the following steps:

[0057] Step 1, start the ball screw mechanism 2, drive the first nut sleeve structure 3 and the second nut sleeve structure 4 on the corresponding side through the ball screw mechanism 2, and then drive the first nut sleeve structure 3 and the second nut sleeve structure 4 The respective multi-link mechanism 5 drives the corresponding clamping arm structure 6 to open through the multi-link mechanism 5, so that it is close to the central axis of the AGV trolley and ensures that it can pass through the bottom of the car smoothly;

[0058] Step 2, the entire contracted tire clamping device is carried by the AGV trolley and moved to the bottom of the car, and the respective symmetrical centerlines of the four pairs of clamping arm structures 6 are roughly aligned with the axis line of the vehicle wheel to ensure that ...

Abstract

The invention discloses a multi-connecting-rod type tire clamping device carried on an AGV and an operation method of the multi-connecting-rod type tire clamping device. The multi-connecting-rod typetire clamping device comprises two sets of opening-closing-type tire clamping mechanisms arranged symmetrically and used for synchronously clamping and lifting four wheels of an automobile; each set of opening-closing-type tire clamping mechanism comprises a ball lead screw mechanism used for providing driving force, and each ball lead screw mechanism is provided with a first nut sleeve structureand a second nut sleeve structure in a threaded transmission fit mode; and multi-connecting-rod mechanisms used for achieving opening-closing actions are hinged to the two ends of the first nut sleevestructures and the two ends of the second nut sleeve structures correspondingly, and the executing tail end of each multi-connecting-rod mechanism is connected with a clamping arm structure used forbeing matched with the outer walls of automobile tires for clamping. The two sets of tire clamping devices are symmetrically arranged on the AGV, clamping claws are opened and closed through an opening-closing mode, then the clamping claws are matched with the two sides of the automobile tires in a contact mode to clamp the automobile tires, thus the automobile is lifted away from the ground and carried and moved through the AGV conveniently, and automatic parking is achieved.

Description

technical field [0001] The invention relates to a multi-link tire clamping device mounted on an AGV trolley and an operation method, belongs to the technical field of intelligent parking robots, and is suitable for automatic transportation of automobiles in vertical car garages. Background technique [0002] The intelligent three-dimensional garage plays a very good role in alleviating the tension of parking spaces. In order to realize intelligent automatic parking, it is necessary to design an AGV car for car handling. In order to realize the automatic handling of cars, it is necessary to lift the car and park it on the AGV car. , and then move it to the designated position by the AGV trolley and then put it down. In this process, a tire clamping device is needed for lifting the car. [0003] Although, our company discloses telescopic tire clamping device in CN 206562812 U, it adopts four pairs of telescopic tire clamping devices, and each pair of tire clamping devices incl...
