Description

Technical Field

[0001] The present invention relates to the field of three-dimensional parking garages, and particularly to a steering mechanism and a three-dimensional parking garage. Background Art

[0002] The rise of three-dimensional parking garages in the prior art has solved the problem of few parking spaces, but the subsequent problem is that electric vehicles cannot simultaneously meet the problems of parking and charging.

[0003] Chinese Patent Publication No. CN 116714455A, with the name "Three-dimensional Parking Garage with Charging Function", discloses that: the transmission mechanism includes a plurality of transmission units, the transmission unit includes a chain drive plate, chain plates respectively connected to both sides of the chain drive plate, and a plurality of chain plates connected to the chain plates. Adjacent transmission units are connected end to end to form a transmission mechanism. The chain drive plate is trapezoidal, and the chain drive plate and the chain plate are located at the acute angle of the chain drive plate.

[0004] In the above technical solution, the transmission mechanism, the guiding mechanism, and the power-taking mechanism are all located in the main track, so that to ensure that the car-carrying plate in the car-carrying mechanism has sufficient operating space, the main track requires a relatively large space width and height. As a result, the overall garage occupies a relatively large site and space, and the oil stain required for the chain operation will also cause potential safety hazards to the power-taking mechanism. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a steering mechanism and a three-dimensional parking garage.

[0006] The technical solution of the present invention is as follows: A steering mechanism, including a roller chain and a plurality of steering components evenly distributed and installed on the roller chain. The steering component includes a driving arm plate with a driving slider mounting hole at one end, a steering frame, a spherical bearing, and a cantilever shaft sequentially passing through the steering frame, the driving slider mounting hole, and the spherical bearing. The other end of the driving arm plate is respectively connected to the roller chain.

[0007] The above-mentioned steering frame includes a steering frame body composed of a base and a wing plate arranged in parallel and a connecting column connecting the base and the wing plate, a plurality of running wheel shafts parallelly passing through the base, running wheels installed at both ends of the running wheel shafts, guiding wheels placed between the base and the wing plate, and a plurality of guiding wheel shafts parallel and perpendicular to the running wheel shafts and sequentially passing through the base, the guiding wheels, and the wing plate.

[0008] The above-mentioned spherical bearing includes a sphere with a sphere mounting hole axially opened, an upper ball sleeve and a lower ball sleeve respectively sleeved outside the sphere, a first tapered roller bearing and a second tapered roller bearing sequentially sleeved on the cantilever shaft and located in the sphere mounting hole, a tightening nut for fixing the spherical bearing on the cantilever shaft, and an oil groove is opened on the outer circumference of the sphere.

[0009] The above-mentioned cantilever shaft is engaged with the driving slider mounting hole through the driving slider, and the driving slider is located between the spherical bearing and the bogie body.

[0010] Furthermore, it also includes a slip ring axially passing through the cantilever shaft.

[0011] A current collector is axially inserted at the bottom of the above-mentioned cantilever shaft, and the current collector runs inside the box-type sliding contact wire.

[0012] A multi-story parking garage includes a steering mechanism, a track mechanism for the operation of the steering mechanism, a driving mechanism for driving the steering mechanism to operate inside the track mechanism, and a vehicle-carrying mechanism that operates together with the steering mechanism.

[0013] The above-mentioned vehicle-carrying mechanism includes a vehicle-carrying plate, a vehicle-carrying back plate hinged to one end of the vehicle-carrying plate. The sides of the vehicle-carrying plate and the vehicle-carrying back plate are respectively fixed at both ends by a plurality of diagonal tie rods to maintain the perpendicular setting of the vehicle-carrying plate and the vehicle-carrying back plate; a sliding plate is installed on the back of the vehicle-carrying back plate, and a balance wheel is installed on the sliding plate; an axial sleeve is installed on the upper cross beam of the vehicle-carrying back plate, and the sleeve is used to engage with the spherical bearing, and the spherical bearing is locked by an end cover plate. A buffer pad is fixedly installed at the top of the H-shaped bracket, and a charging pile is also installed on the vehicle-carrying back plate.

[0014] The above-mentioned track mechanism includes a roller chain track for the operation of the roller chain, a main track for the operation of the bogie, an auxiliary track for the operation of the balance wheel of the vehicle-carrying mechanism, and the box-type sliding contact wire is fixed at the bottom of the main track and the opening faces the opening of the main track.

[0015] The above-mentioned driving mechanism includes a reduction motor, a small sprocket installed on the output shaft of the reduction motor, a large sprocket that rotates with the small sprocket, a transmission chain connecting the small sprocket and the large sprocket, a transmission main shaft axially passing through the large sprocket, a driving chain fork sleeved on the transmission main shaft, and a first bearing seat and a second bearing seat respectively supporting both ends of the transmission main shaft; the driving chain fork drives the roller chain to move.

[0016] The beneficial effects of the present invention are as follows: the present invention separates the roller chain track operated by the roller chain from the main track operated by the bogie, and drives the steering assembly through the driving arm plate. Compared with the prior art, the length of the main track can be made shorter, the width can be made narrower and the depth can be made shallower, so that the overall occupied area of ​​the parking garage is reduced and the occupied space is smaller; in addition, since the running track of the bogie and the running track of the roller chain are not in the same track, resulting in different angular velocities, the vehicle loading plate can quickly pull away from other vehicle loading plates that have not yet entered the curve at a faster speed when passing through the arc of the main track to avoid collision with adjacent vehicle loading plates; in addition, the running surface of the slide plate of the auxiliary track and the back plate of the vehicle loading plate is higher than the running surface of the steering mechanism of the main track, which means that the main track and the auxiliary track run in layers without interfering with each other, so it is beneficial to the synchronous layout of the auxiliary track relative to the main track, and the narrower main track can connect more auxiliary tracks, which is beneficial to the balance and smooth operation of the vehicle loading mechanism.

Detailed implementation mode

[0019] To better illustrate the present invention, further explanations are given below in combination with embodiments and drawings. Embodiment

[0020] As Figures 1 to 14 shown, the steering mechanism 1 includes a roller chain 12 and a plurality of steering components 11 evenly distributed and installed on the roller chain 12. The steering component 11 includes a driving arm plate 113 with a driving slider mounting hole 119 opened at one end, a bogie 111, a spherical bearing 112, a cantilever shaft 118 sequentially passing through the bogie 111, the driving slider mounting hole 119 and the spherical bearing 112, and the other end of the driving arm plate 113 is respectively connected to the roller chain 12.

[0021] Specifically, the bogie 111 includes a bogie body 1111 composed of a base 11111 and a wing plate 11113 arranged in parallel and a connecting column 11112 connecting the base 11111 and the wing plate, a plurality of running wheel shafts 1112 parallelly passing through the base 11111, running wheels 1113 installed at both ends of the running wheel shafts 1112, guide wheels 1115 placed between the base 11111 and the wing plate 11113, and a plurality of guide wheel shafts 1114 parallel and perpendicular to the running wheel shafts 1112 and sequentially passing through the base 11111, the guide wheels 1115 and the wing plate 11113.

[0022] Specifically, the spherical bearing 112 includes a sphere 1121 axially provided with a sphere mounting hole, an upper ball sleeve 1122 and a lower ball sleeve 1123 respectively sleeved outside the sphere 1121, a first tapered roller bearing 1124 and a second tapered roller bearing 1125 sequentially sleeved on the cantilever shaft 118 and located within the sphere mounting hole 11212, and a tightening nut 116 for fixing the spherical bearing 112 on the cantilever shaft 118. The tightening nut 116 functions to tightly compress the second tapered roller bearing 1125, thereby fixing the spherical bearing 112 on the cantilever shaft 118, ensuring that during cornering and steering of the car-carrying mechanism 4, the rotational frictional resistance of the steering assembly 11 is reduced, and during the movement of the car-carrying mechanism 4, the spherical bearing 112 provides good centripetal force to ensure the smooth operation of the car-carrying mechanism 4; after the tightening nut 116 is installed, the driving slider 115 and the driving arm plate 119 are also fixed between the spherical bearing 112 and the bogie 111. An oil groove 11211 is provided on the outer periphery of the sphere 1121, and lubricating oil is injected into the oil groove 11211 through the upper ball sleeve 1122 to reduce the frictional force between the sphere 1121 and the upper ball sleeve and the lower ball sleeve 1122.

[0023] Furthermore, the cantilever shaft 118 is engaged with the driving slider mounting hole 119 through the driving slider 115, and the driving slider 115 is located between the spherical bearing 112 and the bogie body 1111. It also includes a slip ring 117 axially passing through the cantilever shaft 118, and the slip ring 117 functions to prevent knotting and entanglement during the transmission of electricity. A current collector 114 is axially inserted at the bottom of the cantilever shaft 118, and the current collector 114 operates within the box-type sliding contact wire 13. Embodiment

[0024] As Figures 1 to 14 shown, the three-dimensional parking garage includes a steering mechanism 1, a track mechanism 2 for the operation of the steering mechanism 1, a driving mechanism 3 for driving the steering mechanism 1 to operate within the track mechanism 2, and a car-carrying mechanism 4 that operates together with the steering mechanism 1.

[0025] Specifically, the car-carrying mechanism 1 includes a car-carrying plate 41, a car-carrying back plate 42 connected to one end of the car-carrying plate 41 through a hinge 44. The sides of the car-carrying plate 41 and the car-carrying back plate 42 are respectively fixed at both ends by a plurality of diagonal tie rods 43 to maintain the perpendicular setting of the car-carrying plate 41 and the car-carrying back plate 42; a slide plate 49 is installed on the back of the car-carrying back plate 42, and a balance wheel 48 is installed on the slide plate 49; an axial sleeve 47 is installed on the upper cross beam of the car-carrying back plate 42, and the sleeve 47 is used to engage with the spherical bearing 112, and the spherical bearing 112 is locked by an end cover plate 422. A buffer pad 46 is fixedly installed at the top of the H-shaped bracket 45 fixedly installed at the top of the car-carrying back plate 42. The H-shaped bracket 45 is close to or in contact with the car-carrying mechanism above the car-carrying mechanism 1 during operation to prevent the car-carrying mechanism 1 from falling and hitting the car parked on this car-carrying mechanism 1; a charging pile 421 is also installed on the car-carrying back plate 42 to meet the charging safety requirements of electric vehicles.

[0026] Specifically, the track mechanism 2 includes a roller chain track 23 for the roller chain 12 to run, a main track 21 for the bogie 111 to run, and an auxiliary track 22 for the balance wheel 48 of the car-carrying mechanism 1 to run; the roller chain track 23 is arranged inside the inner ring of the main track 21, and the box-type sliding contact wire 13 is fixed at the bottom of the main track 21 and the opening faces the opening of the main track 21.

[0027] Specifically, the driving mechanism 3 includes a reduction motor 31, a small sprocket 32 installed on the output shaft of the reduction motor 31, a large sprocket 34 rotating with the small sprocket 32, a transmission chain 33 connecting the small sprocket 32 and the large sprocket 34, a transmission main shaft 37 passing through the axis of the large sprocket 34, a driving chain fork 38 sleeved on the transmission main shaft 37, a first bearing block 35 and a second bearing block 36 respectively supporting both ends of the transmission main shaft 37; the driving chain fork 38 drives the roller chain 12 to move. The roller chain 12 drives the bogie 111 in the steering assembly 11 to run inside the main track 21. The auxiliary tracks 22 are distributed on both sides of the main track 21, namely the left and right auxiliary tracks and the upper and lower auxiliary tracks; the sliding surfaces of the grooves of the auxiliary tracks 22 are in sliding contact with the sliding plates 49 on the back of the car-carrying plate 42, especially the lower sliding plates, which serve to support the car-carrying plate and reduce the running resistance and running noise; the middle grooves of the auxiliary tracks 22 are for accommodating the balance wheels 48 behind the back plate of the car-carrying plate. Since the auxiliary tracks 22 are distributed relative to the main track 21, the running tracks of the balance wheels 48 on both sides of the back plate 42 of the car-carrying plate relative to the cantilever shafts 118 of the bogie 111 running inside the main track 21 are out-of-track synchronous. Therefore, the movement of the cantilever shafts 118 of the bogie 111 is equivalent to the synchronous operation of the balance wheels 48. The balance wheels 48 on both sides of the back plate 42 of the car-carrying plate run synchronously and turn in the left and right and upper and lower auxiliary tracks 22 respectively, so it can play a leveling role. Thus, in the case of a single-sided suspended car-carrying mechanism 4, the smooth and balanced operation of the car-carrying plate 4 is ensured.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, or improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
