Description

Technical Field

[0001] The present invention relates to the field of three-dimensional parking garage equipment, and more specifically to an underground parking garage with a vehicle conversion position configured at the lifting position. Background Art

[0002] At present, the problem of difficult parking in cities has become a social problem and even more a people's livelihood issue. Now, it is not only difficult to park in first- and second-tier cities, but also third- and fourth-tier cities are facing the problem of difficult parking. Currently, in residential communities and some public places, most parking lots are mainly for ground parking. Due to limited ground space, it is difficult to build a large number of ground parking lots. Especially in first- and second-tier cities where every inch of land is precious, it is impossible to set aside large areas of land to build ground parking lots. To solve the problem of difficult parking, building a three-dimensional parking garage is the only choice. However, the general three-dimensional parking garage requires a large area of land, and not all plots are suitable for building large three-dimensional parking garages. For old residential communities, there is simply no land available to build a three-dimensional parking garage. Especially when building an above-ground three-dimensional parking garage, the surrounding building facilities need to be considered. If it blocks the light of other buildings or affects the overall layout, it is also difficult to be implemented.

[0003] Moreover, traditional three-dimensional parking garages all adopt car-carrying plates. When storing and retrieving vehicles, it is impossible to achieve non-avoidance vehicle storage and retrieval, the vehicle storage and retrieval speed is low, the waiting time for vehicle storage and retrieval is long, and the user experience is not good. This makes it very difficult for such parking garages to be popularized.

[0004] Due to the low efficiency of vehicle storage and retrieval in lifting and traversing parking garages, it is not advisable to set too many parking spaces for such parking garages. To increase the number of parked vehicles, multiple lifting and traversing garages can also be connected in parallel or arranged longitudinally. For multiple lifting and traversing parking garages arranged longitudinally, multiple elevators need to be configured, which will increase the cost. Moreover, each garage requires a separate control system, increasing the cost and the resources cannot be fully utilized. Multiple elevator workstations cannot be used as vehicle storage workstations. Too many elevator workstations will reduce the vehicle storage rate, and the number of parked vehicles will decrease under the same land area.

[0005] Therefore, how to provide a parking garage with less occupied space, a large vehicle storage capacity, and convenient vehicle parking and retrieval is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] The present invention solves at least one of the above technical problems in the prior art to a certain extent.

[0007] In view of this, the present invention aims to provide an underground parking garage with a vehicle conversion position configured in the lifting position, adopting a parking structure with a multi-layer carrier frame embedded in a pit. Lifting openings are provided at both ends and in the middle of the pit, and a conversion opening is provided at the middle lifting opening; the lifting openings, the conversion opening and the garage entrance and exit are coordinated to operate for parking and retrieving vehicles simultaneously, realizing the rapid retrieval of different parking spaces in the parking garage; improving the vehicle retrieval speed and reducing the waiting time; and the underground structure greatly alleviates the problem of insufficient above-ground parking space and avoids congestion; it has great advantages for the problem of lack of parking spaces and difficult renovation in old communities due to planning problems.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An underground parking garage with a vehicle conversion position configured in the lifting position is arranged in a pit and includes a garage frame body, a lift and a transmission device.

[0010] The garage frame body includes a fixed carrier frame, a transfer carrier frame, a parking carrier board guide rail, a transfer carrier board guide rail, a parking carrier board and a transfer carrier board.

[0011] The fixed carrier frame includes multiple layers arranged horizontally and parallel to each other and is fixed to the side wall of the pit; lifting channels are reserved on both sides and in the middle of the pit.

[0012] The number of the transfer carrier frames corresponds to the number of the lifting channels; the transfer carrier board guide rails are fixed on both sides of the corresponding transfer carrier frames; the parking carrier board guide rails are fixed at both ends of the fixed carrier frame; the transfer carrier board guide rails and the parking carrier board guide rails can be adapted to output vehicles.

[0013] Vehicle conversion positions are reserved on both sides at the top of the middle lifting channel and on the side of both ends of the lifting channel facing the middle corresponding to the top fixed carrier frame; the number of the lifts is the same as that of the transfer carrier frames and they are installed in the corresponding lifting channels and drive the corresponding transfer carrier frames to move up and down to transport vehicles.

[0014] There are multiple parking carrier boards, and multiple parking carrier boards and multiple transfer carrier boards are sequentially slidably connected to the fixed carrier frame and the transfer carrier frame along the vehicle output direction in a switchable manner; the number of the transfer carrier boards is less than the number of the transfer carrier board guide rails.

[0015] The transmission device is installed on the transfer carrier frame and the fixed carrier frame of the vehicle conversion position; to drive the conversion between the transfer carrier board and the parking carrier board.

[0016] As can be seen from the above technical solutions, compared with the prior art, the present invention discloses an underground parking garage with a vehicle conversion position configured at the lifting position, which is more convenient for construction. When picking up a vehicle, according to the pick-up position, the elevators in the lifting channels on both sides thereof push the transfer carrier frame up to the parking layer at the same height as the vehicle, and one of the two transfer carrier frames does not have a transfer carrier board. The transmission device on the transfer carrier frame equipped with the transfer carrier board drives the transfer carrier board to move. The transfer carrier board contacts the parking carrier board of the adjacent parking space and pushes the parking carrier boards on this layer to move in sequence until the vehicle and the parking carrier board on the other side move onto the transfer carrier frame without the transfer carrier board. At this time, the two transfer carrier frames move to another parking space layer simultaneously. The transmission device on the movable carrier frame equipped with the transfer carrier board and the vehicle pushes the transfer carrier board and the vehicle into the parking space on this layer. The vehicle and the parked vehicle carrier board on the other side of the parking space on this layer are pushed into the movable carrier frame on the other side. The two movable carrier frames continue to return to the original parking layer and repeat the previous operation until the vehicle is taken out. By setting vehicle conversion positions in the middle and at both ends, when a vehicle pick-up operation needs to be carried out, the vehicle to be picked up is moved to the conversion position in advance to wait, which does not affect the operation of moving vehicles in the underground garage. When parking, the parking carrier board or the transfer carrier board is pre-moved to the conversion position to wait, which is convenient for timely parking operations. This technical solution can take out the vehicle at the appropriate vehicle conversion position according to the optimal path. At the same time, the number of parked vehicles is larger, the cost is lower, the pick-up time is saved, and pick-up congestion is avoided. It effectively saves the ground space, the garage structure is simple, the construction difficulty is low, the construction limitation is low, and the safety of the underground garage is higher.

[0017] In the above-mentioned underground parking garage with a vehicle conversion position configured at the lifting position, both the parking carrier board guide rail and the transfer carrier board guide rail are C-shaped pipes, which are respectively fixed on the opposite sides of the fixed carrier frame and the transfer carrier frame close to the side wall of the pit.

[0018] Four groups of roller sets are installed diagonally on both sides of the parking carrier board and the transfer carrier board. The roller set includes a moving wheel and a locking wheel. The moving wheel rolls on the inner wall of the parking carrier board guide rail or the transfer carrier board guide rail, and the locking wheel is clamped with the locking device. This solution can move through the moving wheel in the carrier board guide rail and ensure its lateral distance through the locking wheel. Through its locking operation, it can prevent the vehicle from slipping. When moving through the joint of the guide rail, at least multiple sets of driven wheels can be ensured to be in a section of the carrier board guide rail, so as to prevent the carrier board from being skewed or unable to smoothly enter another section of the carrier board guide rail.

[0019] In the above-mentioned underground parking garage with a vehicle conversion position configured at the lifting position, the transmission device includes: a first sprocket group, a second sprocket group, a bearing seat, a reduction motor, and a stop block.

[0020] The first sprocket set includes a first driving sprocket and a first driven sprocket, and is connected by a first chain; the second sprocket set includes a second driving sprocket and a second driven sprocket, and is connected by a second chain, and two chain plate push rods with opposite directions are connected to the second chain. When one of the chain plate push rods is correspondingly located at the position of the second driving sprocket or the second driven sprocket of the second chain, the other chain plate push rod is correspondingly located at the position of the second driven sprocket or the second driving sprocket.

[0021] The first driving sprocket, the first driven sprocket, the second driving sprocket and the second driven sprocket are all penetrated by a sprocket shaft and are fixedly connected to the sprocket shaft; a plurality of the sprocket shafts are correspondingly installed on a plurality of bearing seats and are rotatably connected thereto; the bearing seat installed with the first driving sprocket is fixed in the middle of the transfer carrier frame and the fixed carrier frame at the vehicle conversion position; the output shaft of the reduction motor is fixedly connected to the sprocket shaft of the first driving sprocket; the bearing seat installed with the first driven sprocket is fixed on one side of the transfer carrier frame and the fixed carrier frame at the vehicle conversion position perpendicular to the parking carrier plate guide rail and the transfer carrier plate guide rail; the second driving sprocket and the first driven sprocket are penetrated at both ends of the same sprocket shaft, and the bearing seat installed with the second driven sprocket is fixed on the opposite side of the installation of the second driving sprocket.

[0022] Two of the stoppers are respectively fixed on both sides of the parking carrier plate and the transfer carrier plate perpendicular to the parking carrier plate guide rail and the transfer carrier plate guide rail; the two stoppers can alternately abut against the corresponding chain plate push rods through the movement of the second chain; in this solution, the chain drive can reduce costs, has a simple and reliable structure, low failure rate, and a relatively high transmission speed; and the stroke of the chain drive is adjustable. When the carrier plate is conveyed and positioned, sufficient clearance can be left for the movable guide rail at the lifting station and the fixed guide rail in the shaft to ensure that the elevator will not rub against the fixed guide rail during the lifting operation.

[0023] In the above underground parking garage with a vehicle conversion position configured at the lifting position, an angular displacement encoder and a positioning sensor are further provided, both of which are arranged at the chain plate push rod of the second chain; in this solution, the chain drive process can adopt an absolute value coding control composed of an angular displacement encoder and a positioning sensor. When the carrier plate receives a running instruction, the push rod is moved to the pre-action starting position in advance, reducing the running waiting time and improving the vehicle access efficiency.

[0024] In the above-mentioned underground parking garage with a vehicle conversion position in the lifting position, the elevator includes: a lifting device and an elevator guide rail device; the lifting device includes a ball screw assembly and a screw base, and the screw base is fixed to the bottom and top side walls of the lifting channel; the screw of the ball screw assembly is perpendicular to the bottom of the multi-story parking garage, and its two ends are respectively installed in the screw base and rotatably connected thereto; the screw nut of the ball screw assembly is fixed to one side of the transfer carrier frame; the ball screw assembly is equipped with a suitable speed reducer and a lifting motor, and the lifting motor drives the screw and drives the transfer carrier frame to reciprocate up and down from the bottom to the top of the multi-story parking garage;

[0025] The elevator guide rail device includes a lifting auxiliary guide rail, an embedded roller assembly and a connecting plate; the lifting auxiliary guide rail is square tubular, and a strip-shaped opening is formed on one side wall along its length direction; multiple lifting auxiliary guide rails are provided, vertically and parallelly arranged on one side or the opposite side of the transfer carrier frame where the ball screw assembly is installed;

By setting multi-directional embedded wheels in the auxiliary guide rail, rolling lifting is realized, while friction is reduced, avoiding the deviation of the transfer carrier frame, and making the lifting and descending processes more stable; the transfer carrier frame is lifted by the ball screw device, the control of the lifting height accuracy is more precise, the movement process is smoother, and self-locking can be realized when the lifting stops, with higher safety.

[0027] In the above-mentioned underground parking garage with a vehicle conversion position in the lifting position, the lifting auxiliary guide rail is a C-shaped steel;

[0028] One side of the roller frame is an H-shaped steel, and the web of the H-shaped steel extends towards the other side to form a fixing plate, and the roller frame is vertically sleeved in the C-shaped steel;

[0029] The roller rack further includes a roller rotating shaft and an embedded wheel; the roller rotating shaft includes a first roller rotating shaft and a second roller rotating shaft. There are two first roller rotating shafts, and the two roller rotating shafts are respectively rotatably connected in parallel and symmetrically to the flange plates on both sides of the H-shaped steel web, parallel to the web; the second roller rotating shaft is horizontally passed through the fixing plate and perpendicular to the fixing plate; the two embedded wheels are respectively installed on the two first roller rotating shafts between the flange plates; the four embedded wheels are respectively installed in groups of two at both ends of the two second roller rotating shafts;

[0030] One end of the connecting plate passes through the strip-shaped opening of the C-shaped steel and is fixed on the fixing plate; in this solution, there are multiple groups of embedded wheels with different directions, which are respectively in rolling connection with different inner walls of the lifting auxiliary guide rail to play a limiting role and make the lifting process smoother.

[0031] In the above-mentioned underground parking garage with a vehicle conversion position configured at the lifting position, the ball screw assemblies of the lifting channels at both ends of the pit are installed on one side of the transfer carrier frame close to the side wall of the pit and perpendicular to the transfer carrier plate guide rail; there are two lifting auxiliary guide rails, and the two lifting auxiliary guide rails are installed on the same side of the ball screw assembly;

[0032] The ball screw assemblies of the lifting channels in the middle of the pit are installed on both sides of the transfer carrier frame where the transfer carrier plate guide rail is installed; there are four lifting auxiliary guide rails, which are diagonally distributed on the same side and the opposite side of the ball screw assembly; this solution can ensure the smoothness of transportation while ensuring that the lifting auxiliary track will not hinder the transmission movement.

[0033] In the above-mentioned underground parking garage with a vehicle conversion position configured at the lifting position, the lifting device of the lifting channel in the middle further includes a first gear set, a first transmission rod, a second gear set, a second transmission rod and a third gear set;

[0034] Both ends of the first transmission rod and the second transmission rod are respectively passed through and installed in bearing seats, and the first transmission rod and the second transmission rod are horizontally installed at intervals along their lengths between the screw bottoms of the two ball screw assemblies through the bearing seats;

[0035] The first gear set has three bevel gears, which are respectively fixed on the output shaft of the reducer, one end of the screw bottom of one of the ball screw assemblies and one end of the first transmission rod, and the bevel gear at one end of the screw bottom is respectively meshed with the other two bevel gears;

[0036] The second gear set is provided with three bevel gears, two of which are respectively fixed at the other end of the first transmission rod and one end of the second transmission rod, and the remaining one bevel gear is fixed at one end of the rotating shaft and is rotatably connected to the bearing seat through the rotating shaft, and the bearing seat is fixed at the bottom of the three-dimensional parking garage; the two bevel gears fixed at the other end of the first transmission rod and one end of the second transmission rod are respectively meshed with the bevel gear fixed on the bearing seat;

[0037] The third gear set is provided with two bevel gears, which are respectively sleeved at the other end of the second transmission rod and one end of the bottom of the lead screw of another ball screw assembly, and the two bevel gears of the third gear set are meshed with each other; this solution is more suitable for the case where the length of the transfer carrier frame is relatively long. By symmetrically arranging the ball screw assemblies on both sides of the transfer carrier frame, the stiffness requirement for the transfer carrier frame is reduced, materials are saved, costs are reduced, the synchronization of the ball screw assemblies on both sides is ensured, and at the same time, the stability and smoothness of the lifting and lowering processes are further ensured.

[0038] In the above underground parking garage with a vehicle conversion position configured at the lifting position, the locking device includes: a sliding fork block, an assembly plate, a link mechanism, an electric cylinder and a fixed seat;

[0039] The two ends of the sliding fork block are respectively a connection end and a clamping end. A first strip-shaped sliding hole extending towards the clamping end is opened at the connection end, and a first through hole is opened near the clamping end; the clamping end can be detachably connected with the locking wheel;
