Description

TECHNICAL FIELD

[0001] The present application belongs to the field of mechanical vehicle storage devices, and particularly relates to a mechanical parking equipment for storing and taking vehicles in a comb-tooth exchange mode. BACKGROUND

[0002] A mechanical parking solution for storing and taking vehicles in a comb-tooth exchange mode is described in CN201310060240.6, which has the technical features including a plurality of fixed comb frames arranged transversely between two horizontal tracks, each fixed comb frame including a front-to-back overhead longitudinal fixed comb beam, and fixed comb teeth extending outwardly and transversely on both sides of the front and back of the fixed comb beam. A carrier moves along the horizontal tracks and above each fixed comb frame. The carrier is provided with a gantry-type lifting frame. The lifting frame includes a top frame, and lifting frame vertical arms are arranged at the four corners of the top frame. The bottom end of each lifting frame vertical arm is provided with a lifting frame comb beam extending longitudinally and oppositely, and the lifting frame comb beam is provided with lifting frame comb teeth extending transversely and oppositely. When the lifting frame is lowered to the lower limit position, the lifting frame comb beams and the lifting frame comb teeth of the lifting frame pass through the overhead passage space below the front and back of each fixed comb frame, following the carrier. When the carrier moves to a position directly above a fixed comb frame, the lifting frame comb teeth can pass through the tooth gap of the fixed comb frame under the action of the lifting and lowering of the lifting frame, so as to take or place a vehicle.

[0003] The actual verification of the marketed product proves that the technology has the following defects:

[0004] 1. In order to adapt to wheels with different wheelbase, the four groups of lifting frame comb beams and lifting frame comb teeth that are separated from each other need to extend outwardly and suspendingly by about 1.8 meters from the root. Under the pressure of a heavy vehicle body, the long suspended structure section will deform due to deflection, causing a significant relative horizontal displacement between the lifting frame vertical arms and the lifting frame comb teeth. When the carrier performs lifting and horizontal movement, the lifting frame comb teeth will shake and deform, which is difficult to control and is prone to tooth collision accidents.

[0005] 2. In order to overcome the above defects, the commonly used technical means is to increase the cross-sectional size of the lifting frame vertical arms and the lifting frame comb beams, to strengthen the structural strength, to reduce the deflection, and to shorten the suspension length of the lifting frame comb beams as much as possible. However, this will increase the cost, reduce the reliability of the force-bearing components, increase the space occupied by the components, make it difficult to improve the carrying capacity, and make it difficult to carry long vehicle bodies, etc., which affects the performance of the product.

[0006] With the gradual popularization of new energy vehicles, the size and weight of the vehicle models have increased significantly, and the above technical defects need to be solved urgently. SUMMARY

[0007] In order to solve the defects of the prior art, the present application proposes the following technical solutions, as shown in the accompanying drawings:

[0008] This is a parking equipment which exchanges and lifts up the vehicles with comb teeth,

[0009] The structure includes a base frame 1, the base frame 1 includes two transversely extending cross rails 11;

[0010] It includes a plurality of fixed comb frames 12 for placing vehicles 3 arranged transversely between the two cross rails 11,

[0011] The fixed comb frame 12 includes a longitudinally fixed comb beam 121 with front and rear parts in the air, and the left and right sides of the front and rear parts of the fixed comb beam 121 have outward transversely suspended fixed comb teeth 122;

[0012] It includes a carrier 2 which moves transversely above each fixed comb frame 12 along the cross rail 11;

[0013] In the middle space of the carrier 2, there is a liftable gantry type lifting frame 22,

[0014] The structure of the lifting frame 22 includes a top frame 221, and the bottom of each corner of the top frame 221 is provided with a lifting frame vertical arm 222, the bottom end of each lifting frame vertical arm 222 is provided with a longitudinally oppositely suspended lifting frame comb beam 223, and each lifting frame comb beam 223 is provided with a transversely oppositely suspended lifting frame comb tooth 224;

[0015] When the lifting frame 22 is lowered to the lower limit position, each lifting frame comb beam 223 and the lifting frame comb tooth 224 of the lifting frame 22 pass through the suspended passage space below the front and rear parts of each fixed comb frame 12 following the carrier 2;

[0016] When the carrier 2 moves to the alignment position directly above one fixed comb frame 12, each lifting frame comb tooth 225 can pass through the corresponding tooth gap of the fixed comb frame 12 under the driving of the lifting action of the lifting frame 22;

[0017] The features are:

[0018] The position close to the suspended end of each lifting frame comb beam 223 of the lifting frame 22 is provided with a comb beam hook 225;

[0019] The left front and back and the right front and back of the lifting frame 22 are respectively provided with a longitudinal moving hoist 231 which can move longitudinally between a working position and a yielding position;

[0020] The bottom end of the longitudinal moving hoist 231 is provided with a hoist bottom hook 234;

[0021] When the longitudinal moving hoist 231 moves to the working position, the hoist bottom hook 234 and the corresponding comb beam hook 225 are hooked with each other, and the top of the longitudinal moving hoist 231 is connected to the top frame of the lifting frame 22;

[0022] When the longitudinal moving hoist 231 moves to the yielding position, the longitudinal moving hoist 231 is close to the lifting frame vertical arm 222.

[0023] When the carrier 2 needs to lift a vehicle on a fixed comb rack 12, before the aligned lifting frame 22 starts to lift, the four longitudinal moving hoists 231 are moved inward to the working position, and the hoist bottom hooks 234 and the comb beam hooks 225 are hooked to the position close to the overhanging end of the lifting frame comb beam 223. Then, when the lifting frame 22 starts to lift, the four longitudinal moving hoists 231 and the four lifting frame vertical arms 222 jointly lift the four wheels of the vehicle at eight evenly distributed lifting points, so that the front and rear ends of each lifting frame comb beam 223 are synchronously provided with reliable lifting force, not only effectively solving the stress deformation problem of the prior art, but also prolonging the length of the vehicle allowed to enter the garage by significantly lengthening the length of the lifting frame comb beam 223. The evenly distributed lifting points can also significantly increase the allowable load of the equipment without increasing the size and material of the related steel structure, and adapt to heavy vehicles. When the lifting frame 22 rises to the upper limit position, the carrier 2 can allow a higher safety transverse moving speed because the vehicle has been evenly lifted by multiple lifting points. The longitudinal moving process of the longitudinal moving hoist 231 can be completed in a very short time, and the carrier 2 can run at a higher speed, which will not affect the vehicle storage and retrieval efficiency.

[0024] In order to strengthen the reliability of the connection node at the upper part of the longitudinal moving hoist 231 and the stability of the longitudinal moving process,

[0025] Preferably,

[0026] The top of the longitudinal moving hoist 231 is provided with a hoist top hook 235;

[0027] The left front and back and the right front and back of the lifting frame top frame 221 are each provided with a top frame hook 226;

[0028] When the longitudinal moving hoist 231 moves to the working position, the hoist top hook 235 and the top frame hook 226 are hooked to each other.

[0029] Preferably,

[0030] The left front and back and the right front and back of the lifting frame top frame 221 are each provided with a longitudinal hoist guide rail 228;

[0064] Reference Figure 1 , Figure 2 This is a parking equipment designed according to the basic principles of the invention, which exchanges and lifts the vehicle with comb teeth.

[0065] Its structure includes a steel structure base frame 1 suspended in the air above the ground; the top of the front and rear base frame supports two transversely extending horizontal rails 11 with a clear distance of 6.2 meters.

[0066] The middle part of the front and rear base frame supports is connected by a base frame longitudinal beam 14. The middle part of the base frame longitudinal beam 14 supports two base frame transverse beams 15 above it. Along the top of the base frame transverse beam 15, a row of fixed comb frames 12 for storing vehicles 3-1 are installed at intervals of 2.5 meters.

[0067] The structure of the fixed comb frame 12 includes a front and rear suspended longitudinal fixed comb beam 121, and the left and right sides of the front and rear of the fixed comb beam 121 have outward transversely suspended fixed comb teeth 122. Four groups of fixed comb teeth 122 of each fixed comb frame 12 are used to carry the front and rear wheels of the vehicle 3-1 respectively.

[0068] The structure of the carrier 2 includes a transverse moving frame 21, a lifting frame 22 and a longitudinal moving frame 23.

[0069] The carrier 2 moves along the horizontal rail 11 above each fixed comb frame 12 by relying on the transverse moving frame traveling wheel 211.

[0070] A liftable gantry-type lifting frame 22 is installed in the middle lifting working space of the transporter 2.

[0071] The lifting frame 22 has two sets of longitudinally moving frames 23 on its left and right sides that can move longitudinally relative to each other.

[0072] See Figure 3 , Figure 4 The transverse frame 21 is constructed including transverse frame traveling wheels 211 at the four lower corners. The front and rear ends of the transverse frame 21 have lifting guide bodies 213 that guide the lifting frame 22 to perform lifting and lowering actions.

[0073] The lifting guide body 213 is equipped with a horizontally retractable drag-reducing telescopic body 212.

[0074] See Figure 5 The lifting frame 22 consists of a top frame 221, with lifting frame arms 222 mounted at the four corners of the top frame 221. Each lifting frame arm 222 has a longitudinally cantilevered lifting frame comb beam 223 at its bottom end, and each lifting frame comb beam 223 is equipped with a laterally cantilevered lifting frame comb tooth 224.

[0075] Each lifting frame comb beam 223 of the lifting frame 22 has a comb beam hook 225 that protrudes outward near the cantilever end.

[0076] Vertical lifting guide rails 227 are provided at the center of the front and rear ends of the lifting frame 22. The lifting guide rails 227 move up and down under the guidance of the lifting guide bodies 213 at the corresponding positions at the front and rear ends of the transverse frame 21.

[0077] The lifting guide rail 227 of the lifting frame 22 is provided with a downward locking buckle 2292 on the middle side. See also Figure 11 When the lifting frame 22 rises to the upper limit position, the drag telescopic body 212 in the lifting guide body 213 of the transverse frame 21 can extend and insert into the lower drag buckle 2292 of the lifting guide rail 227 to prevent the lifting frame 22 from descending.

[0078] The upper four corners of the top frame 221 of the lifting platform are provided with outwardly protruding upper locking buckles 2291. See also Figure 12 , Figure 13 When the lifting frame 22 descends to the lower limit position, the upper blocking buckles 2291 at the four corners of the top frame 221 of the lifting frame are supported by the top of the frame of the transverse frame 21, so that the lifting frame 22 is at the preset height and cannot continue to descend.

[0079] See Figure 6Each longitudinal moving frame 23 is composed of two longitudinal moving booms 231 rigidly connected by boom cross link 232, the bottom end of boom 231 is equipped with boom bottom hook 234, the top end is equipped with boom top hook 235, and below boom top hook 235 is boom upper longitudinal 236 which longitudinally overhangs, the inner side of each boom upper longitudinal 236 is equipped with two boom longitudinal moving guide wheels 237.

[0080] Referring to Figure 7 , the boom longitudinal moving guide wheels 237 of the two longitudinal moving frames 23 move along the boom guide rails 228 on the left and right sides of the lifting frame top frame 221 between the working position and the yielding position.

[0081] When the longitudinal moving boom 231 moves to the working position, the boom bottom hook 234 hooks with the corresponding comb beam hook 225, and the boom top hook 235 hooks with the top frame hook 226.

[0082] Referring to Figure 9 , Figure 10 , the longitudinal moving boom 231 moved to the working position allows the two ends of each lifting frame comb beam to be jointly hoisted by the bottom end of the lifting frame vertical arm 222 and the bottom end of the longitudinal moving boom 231, forming a rigid and stable load-bearing structure, which is sufficient to allow the four sets of lifting frame comb teeth 224 to carry heavy vehicles 3.

[0083] Referring to Figure 8 , Figure 12 , Figure 13 When the longitudinal moving boom 231 moves to the yielding position, the longitudinal moving boom 231 is close to the outer side of the lifting frame vertical arm 222, and overlaps the lifting vertical arm 222 transversely, which not only does not hinder the normal movement of the carrier 2, but also does not occupy more longitudinal space, thereby maximizing the provision of a longer vehicle space.

[0084] It is obvious that the operation of each component of the carrier 2 can be realized by using existing mature transmission technology components and control systems, including chain and sprocket system, wire rope system, rack and pinion system, screw rod transmission system, hydraulic transmission system, connecting rod mechanism, reduction motor, sensing system, etc. In the present embodiment and the accompanying drawings, these transmission and control systems are omitted.

[0085] As can be seen from the above embodiment and the accompanying drawings, compared with the prior art, the steel structure of the lifting frame vertical arm 222 has a longitudinal width of less than 10 cm, which can ensure that the lifting frame comb beam 223 does not produce excessive deformation without load, without considering the pressure effect of the load, thereby significantly reducing the amount of steel structure, providing good conditions for low-cost production.

[0086] Since the present application does not involve the technical features of the vehicle access, the vehicle access is omitted in the drawings. In actual application, various mature vehicle access layouts and embodiments can be adopted according to different environments and actual needs.

[0087] In order to minimize the center of gravity of the carrier 2 when the carrier 2 is transversely moved on the carrier vehicle, so that the carrier 2 can be stably and reliably operated at a high speed, the present embodiment adopts a high transverse rail 11 scheme. However, it is obvious that in specific application, a low transverse rail scheme can be adopted, and the transverse moving frame 21 of the carrier 2 can be made into a gantry type carrier shape. However, since the center of gravity of the carrier is high, it is not suitable to operate at a high speed, which affects the access efficiency, and is generally only suitable for occasions with a small number of parking spaces.
