Description

Technical Field

[0001] This invention relates to the field of automated parking garage technology, and more particularly to steering devices. Background Technology

[0002] Among existing technologies, there is a patent with patent number 201711003751.9 and patent name "Automatic Parking Garage" that solves the problem of guiding the guide wheels of an automated parking garage to circulate within the track.

[0003] In the aforementioned patent, the guide structure includes a guide wheel, a guide head, and a guide shaft. The guide wheel is mounted on the guide head in a manner that allows it to rotate around its own axis, and the guide shaft is fixedly connected to the side of the guide head away from the guide wheel. During the cyclic lifting and lowering process, when the frame rises and falls along the straight section of the guide rail, two of the four guide wheels on the frame (two on the left or two on the right) are always inside the guide rail, and the other two are always outside the corresponding guide rail. When the frame rises and falls along the upper arc section, one of the four guide wheels is always inside the guide rail, and another slides into (when the frame is lowering) or out (when the frame is rising) the guide rail through the upper inclined section, leaving the remaining two outside the guide rail. When the frame rises and falls along the lower arc section, one of the four guide wheels is always inside the guide rail, and another slides into (when the frame is rising) or out (when the frame is lowering) the guide rail through the lower inclined section, leaving the remaining two outside the guide rail. When the frame is at the top, the two guide wheels at the highest point are exactly at the highest point of the two guide rails. When the frame is at the bottom, the two guide wheels at the lowest point are exactly at the lowest point of the two guide rails. Due to the guiding effect of the guide wheels and guide rails, the frame will not wobble, thus ensuring the stability of the vehicle on the frame.

[0004] The shortcomings of the above technology are: one of the four guide wheels on the frame is located inside the track, and during the vehicle's cyclic lifting and lowering process, the force on one side of the frame is uneven, which can easily cause the vehicle to fall off the frame. In addition, when the frame is at the top, if a guide wheel that is not inside the guide rail enters the track, it can also easily cause an accident. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a steering device that can operate in both linear and curved guide rails.

[0006] The technical solution of the present invention is as follows:

[0007] A steering device includes a running mechanism, a guiding mechanism fixedly connected to the running mechanism, and a locking mechanism for locking the guiding mechanism to the running mechanism. The running mechanism includes a running frame and at least two sets of running wheels installed on both sides of the running frame and moving with the running frame. The guiding mechanism includes a guiding component and at least two sets of guide wheels installed in the guiding component. The running wheels are arranged perpendicularly to the guide wheels.

[0008] The aforementioned guide component includes a first mounting plate placed on one side of the guide wheel and a second mounting plate placed on the other side of the guide wheel.

[0009] The aforementioned guide component also includes a rib located between the first mounting plate and the second mounting plate and between the adjacent guide wheels.

[0010] The first mounting plate has a first mounting hole, the second mounting plate has a second mounting hole, and the mounting plate also includes a central shaft that passes through the first mounting hole and the second mounting hole in sequence.

[0011] A flange is fixedly installed at one end of the central shaft, and the flange is fixedly connected to a first mounting plate near the running mechanism by a locking screw; the other end of the central shaft is connected to the vehicle carrier.

[0012] The aforementioned guiding component is a guide body, and each of the four corners of the guide body has a groove to accommodate a guide wheel.

[0013] The guide body has a shaft hole at its center, which is parallel to the axial direction of the guide wheel, and also includes a central shaft passing through the shaft hole.

[0014] A flange is fixedly installed at one end of the central shaft, and the flange is fixedly connected to the mounting surface of the guide body near the running mechanism by locking screws; the other end of the central shaft is connected to the vehicle carrier device.

[0015] The aforementioned locking mechanism is a locking screw.

[0016] The aforementioned running frame has a boss at the center of the side away from the guide mechanism, and the boss is nested and connected to the transmission mechanism running in the track.

[0017] The beneficial effects of this invention are as follows: The steering device of this invention includes a running mechanism and a guiding mechanism. When the steering device runs within a linear guide rail, the running wheel of the running mechanism moves within the guide rail; when the steering device runs within an arc-shaped guide rail, the guiding wheel of the guiding mechanism runs within the rail, providing guidance. Thus, the steering device of this invention can run within both linear and arc-shaped guide rails, thereby protecting the vehicle carrier for stable cyclic lifting and lowering within the rail. The steering device receives the axial tension transmitted from the vehicle carrier through its central shaft, and then distributes the torque to the rail through the running wheel and the guiding wheel, thereby protecting the vehicle carrier for stable cyclic lifting and lowering.

The other end of the central shaft 4 is connected to the vehicle carrier 5.

[0053] Specifically, the locking mechanism is a locking screw 26. A boss 13 is provided at the center of the side of the running frame 11 away from the guide mechanism 2. The boss 13 is nested and connected to the transmission mechanism, so that the steering device of the present invention can circulate and move up and down within the track 61.

[0057] Specifically, the locking mechanism is a locking screw 33. A boss 13 is provided at the center of the side of the running frame 11 away from the guide mechanism 2, and the boss 13 is nested and connected to the transmission mechanism; so that the steering device of the present invention can circulate and move up and down within the track 61.

[0058] Example 3

[0059] like Figures 6 to 10 As shown, the vehicle carrier device 5 includes a vehicle carrier plate 51, a back plate frame 52 that is vertically fixed to one side of the short side of the vehicle carrier plate 51, and multiple diagonal tie rods 56 that connect the two long sides of the vehicle carrier plate 51 to the sides of the vertical beams 522 on both sides of the back plate frame 52.

The retaining ring 56 is used to lock the sleeve 55, thereby preventing the sleeve 55 from falling off the spherical bearing 53.

[0061] The central shaft 4 passes sequentially through the center of the first columnar bearing 534, the through hole 5311, and the center of the second columnar bearing 535, and is then locked by the locking nut 536.

[0062] Example 4

[0063] like Figures 11 to 17As shown, the multi-level parking garage track device 6 includes a track 61 and a transmission track installed in the track 61. The track 61 includes two pairs of straight tracks 611 that are perpendicular to and parallel to the ground, and top arc-shaped tracks 612 at the top of the two pairs of straight tracks 611 and bottom arc-shaped tracks 613 at the bottom of the two pairs of straight tracks 611 respectively. The track 61 has a groove-shaped cross section, with the width at the groove opening being smaller than the width at the bottom of the groove. A first running space 614 is provided inside the track 61 near the bottom of the groove, and a second running space 615 is provided inside the track 61 near the groove opening. The first running surface 616 is parallel to the bottom of the track 61, and the second running surface 617 is perpendicular to the first running surface 616.

At the point where the chain component 63 needs to connect with the steering device of the present invention, the outer chain plate 632 is replaced by a chain plate connecting part 64. The chain plate connecting part 64 is a triangular plate with a rectangular hole 644 in the middle. The chain plate connecting part 64 has a mounting hole at the connection point with the adjacent outer chain plate 632. The chain plate connecting part 64 and the adjacent outer chain plate 632 are fixedly connected by a pin 635. The pin 635 passes through the inner chain plate 631 and the outer chain plate 632 in sequence. The end of the pin 635 is equipped with a washer 642 and a pin 643 to prevent the chain from falling off. The boss 13 is placed in the rectangular hole 644 of the chain plate connecting part 64 and fixed by a screw cover plate.
