[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-3The utility model provides a technical solution: a hoist car positioning device, including a mounting seat 1, wherein the mounting seat 1 includes a bearing seat 10, a fixing plate 11 fixedly connected to the bottom of the bearing seat 10, and a mounting plate 12 connected to the fixing plate 11, a reversible positioning square tube 2 is provided on the mounting seat 1, wherein the positioning square tube 2 is provided with a swinging member 3 connected thereto in a transmission manner, and a pushing device 4 connected thereto in a transmission manner to push it to swing, wherein the swinging member 3 includes a rocker rod 30 and a transmission rod 31 fixedly connected to one end of the rocker rod 30, and the pushing device 4 is rotatably connected to the other end of the rocker rod 30. The pushing device 4 of the present application is an electric push rod, but in actual production, a cylinder or other driving component can also be used to position the square tube 2 is connected to the transmission rod 31, so by using the pushing device 4 to push the swing rod 30 to swing, the swing rod 30 can drive the transmission rod 31 to rotate, thereby driving the positioning square tube 2 to flip over. Therefore, when the elevator car needs to stop during the lifting process, the pushing device 4 is first used to push the swing rod 30 to drive the transmission rod 31 to rotate, so that the transmission rod 31 drives the positioning square tube 2 to flip over until the upper surface of the positioning square tube 2 flips to a position parallel to the horizontal plane. Because the bottom of the elevator car itself has a certain thickness, in order to enable the bottom surface of the elevator car to be at the same level as the floor surface after the elevator car stops, the elevator car positioning device in this application needs to be installed below the ground surface, so that the positioning square tube 2 can be turned over. After the positioning square tube 2 is turned into place, its upper surface is still lower than the ground surface. In order to avoid the positioning square tube 2 blocking the lifting of the elevator car after it is turned over, the elevator car needs to be raised for a stage before driving the positioning square tube 2 to turn over, that is, the elevator car needs to be lifted to above the elevator car positioning device of this application, and then the positioning square tube 2 is turned to be parallel to the horizontal plane. At this time, the elevator car can just stop on the positioning square tube 2 when it descends, and the positioning square tube 2 is used to support the bottom of the elevator car. Since the bottom of the elevator car has a certain thickness and the surface of the positioning square tube 2 is also lower than the height of the floor surface, when the elevator car stops on the positioning square tube 2, the bottom of the elevator car The surface is just in the same plane as the floor surface, so when the AGV robot needs to enter and exit the elevator car to transport goods across floors, since the bottom of the elevator car stops on the positioning square tube 2, there will be no height difference between the bottom surface of the elevator car and the ground surface, which can make it easier for the AGV robot to enter and exit the car and ensure the quality of the transported goods. When the elevator car stops at a high floor and needs to be transported to a low floor, due to the obstruction of the positioning square tube 2, the elevator car needs to be lifted up to a certain height, thereby resetting the pushing device 4, thereby driving the rocker arm 30 to swing in the opposite direction, and then driving the positioning square tube 2 to rotate from a flat state to a vertical state, so that it will not block the descent of the elevator car.

[0023] In order to maintain the smooth rotation of the transmission rod 31, the transmission rod 31 and the bearing seat 10 are limited in rotation. The bearing seat 10 is provided with two on the mounting seat 1 for maintaining the smooth rotation of the transmission rod 31. A mounting hole 101 is provided on the bearing seat 10, and each mounting hole 101 is provided with a locating bearing 102 that is limited in rotation therewith. The transmission rod 31 and the locating bearing 102 are limited in rotation. The transmission rod 31 is also provided with a shaft sleeve 32 that is limited in rotation therewith. When the transmission rod 31 is installed between the two bearing seats 10, the shaft sleeve 32 is located between the two bearing seats 10, and the limiting installation between the positioning square tube 2 and the shaft sleeve 32 is used to maintain the connection stability between the positioning square tube 2 and the transmission rod 31.

[0024] In order to enable the pushing device 4 to drive the rocker arm 30 to rotate, a connecting rod 33 is further provided on the rocker arm 30, wherein one end of the electric push rod is rotatably connected to the connecting rod 33. When the electric push rod is extended or retracted, the rocker arm 30 can be driven to rotate through the connecting rod 33. The rocker arm 30 and the transmission rod 31 are arranged orthogonally so that the rocker arm 30 can swing and drive the transmission rod 31 to rotate at the same time. A connecting shaft 40 is also provided on the top of the electric push rod. The connecting shaft 40 is mainly used for the installation of the electric push rod. The positioning square tube 2 and the transmission rod 31 are also arranged orthogonally so that the transmission rod 31 can drive the positioning square tube 2 to flip while rotating.

[0025] Example 2: Please refer to Figure 4 The utility model provides a technical solution: a hoist, which is provided with any hoist car positioning device in the above-mentioned embodiment 1, and the hoist includes a frame 6 and a car 7 that can be raised and lowered in the frame 6, wherein the hoist car positioning device 5 is arranged at the four corners of the frame 6, and is used to support the bottom of the car 7 when the car 7 is parked.

[0026] The working principle of the present invention is as follows: a reversible positioning square tube 2 is provided on the mounting seat 1, and a swinging member 3 is provided at one end of the positioning square tube 2 for transmission connection therewith, and a pushing device 4 is also provided on the swinging member 3 for transmission connection therewith, and the swinging member 3 is pushed by the pushing device 4, so that the swinging member 3 can drive the positioning square tube 2 to flip, thereby enabling the positioning square tube 2 to flip to a position parallel to the horizontal plane, and at this time the upper surface of the positioning square tube 2 is lower than the floor surface, so when the elevator car stops after cross-floor lifting, the elevator car just falls on the positioning square tube 2, and the positioning square tube 2 is used to support the bottom of the elevator car, so since the bottom of the elevator car itself has a certain thickness, the bottom surface of the elevator car and the floor surface are in the same plane at this time, so that there is no height difference between the bottom surface of the elevator car and the floor surface, thereby facilitating the AGV robot to enter and exit the elevator car.
