[0036] 4.

DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0054] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] Embodiment 1

[0056] In this embodiment, a backup anti-fall mechanism is provided, which is used in conjunction with a traction device, and mainly includes a backup chain and an emergency stop unit. The backup chain extends along the length direction of the traction chain of the traction device, and the backup chain can be connected to the lifting vehicle plate; the emergency stop unit is used to stop the backup chain when the traction chain breaks. It should be noted that the traction device can be selected according to needs, such as selecting a bottom chain traction device or a circulating chain traction device.

[0057] As a preferred embodiment, the traction device used in conjunction with the backup anti-fall mechanism in this embodiment is a bottom supporting chain traction device driven by a power unit, which can prevent the lifting vehicle from falling during operation and avoid the safety hazards caused by the breakage of the traction chain in the bottom supporting chain traction device; wherein the bottom supporting chain traction device is a mature existing technology in this field, such as Figure 1 As shown, the traction sprocket 01 is rotated by a power unit (usually a motor reducer), and the traction chain 02 goes from the end point at the lower left side of the figure around the intermediate wheel 1 05 and the intermediate wheel 2 06 arranged under the lifting vehicle plate 03, and finally goes up and is fastened to the frame 04; when the traction chain 02 is in good condition, the lifting vehicle plate 03 is in a balanced state; and when the traction chain 02 breaks, the lifting vehicle plate 03 will lose traction, resulting in overturning, causing a major safety accident.

[0058] The backup anti-fall mechanism of this embodiment can adopt a forced synchronization method, wherein the emergency stop unit includes a fracture detection element, and the fracture detection element is used to detect whether the traction chain is broken. When the traction chain is detected to be broken, the power unit of the bottom chain traction device stops running; wherein, the fracture detection element can be selected as needed, for example, a tension sensor or an acceleration sensor can be selected, and by detecting the tension on the traction chain or detecting the acceleration of the traction chain, it is determined whether the traction chain is broken.

[0059] Combination Figure 1 , Figure 2 As shown, the winding method and installation form of the spare chain 10 are the same as those of the traction chain 02, and the traction sprocket 01 that drives the traction chain 02 is coaxially and tightly installed with the spare sprocket 09 that drives the spare chain 10, so that the traction chain 02 and the spare chain 10 run synchronously and at the same speed; the length of the spare chain 10 is adjusted by the length adjustment unit 11 set on the frame 04, and the right end point thereof is connected to the frame 04 through the length adjustment unit 11; obviously, the length adjustment unit 11 is provided with a compression spring, which will be beneficial to the tensioning of the spare chain 10, which will not be elaborated here.

[0060] When the traction chain 02 breaks, the fracture detection element for detecting the fracture of the traction chain 02 immediately sends a signal, triggering the parking equipment control system to emergency stop the operation of the motor reducer, and the traction sprocket 01 immediately stops rotating, and the spare sprocket 09 stops rotating immediately, so that the spare chain 10 stops moving and takes over the broken traction chain 02 to tug the lifting vehicle plate 03, thereby avoiding the occurrence of overturning accidents.

[0061] Alternatively, the backup anti-fall mechanism of the present embodiment may also adopt a follow-up mode; specifically, the winding mode and installation form of the backup chain rope 10 are the same as those of the traction chain 02, and the backup chain rope 10 is wound around an intermediate wheel that rotates freely around an installation axis, and the backup chain rope 10 is displaced by the lifting and lowering belt action of the lifting vehicle plate, and the installation axis is fixedly installed under the lifting vehicle plate 03 and cannot rotate.

[0062] At this time, the emergency stop unit includes a stop device installed at any position of the intermediate wheel and a fracture detection element for detecting the fracture of the traction chain; wherein, the stop device can be selected according to specific work needs. As a preferred embodiment, the stop device includes a matching meshing rotating member, a stop member and a driving electromagnet; the meshing includes end face tooth meshing, internal and external tooth meshing, flat key meshing, spline meshing and swing key meshing. Specifically, the rotating member is coaxially and tightly installed on the intermediate wheel, and the stop member is arranged on the mounting shaft of the intermediate wheel; the driving electromagnet can drive the stop member to perform axial displacement or swing displacement, so that the stop member and the rotating member can be switched between a meshing state and a disengaged state; the meshing state makes the intermediate wheel unable to rotate, so that the spare chain rope is in a stopped moving state of emergency stop; the disengaged state makes the intermediate wheel able to rotate freely, so that the spare chain rope is in a normal operating follow-up state.

[0063] Furthermore, it needs to be explained that a set of bottom supporting chain traction devices is respectively provided on the upper longitudinal beams on both sides of the longitudinal direction of each lifting vehicle plate of the simple lifting or lifting and transverse shifting parking equipment using a bottom supporting chain traction device, and the traction sprockets of the two sets of bottom supporting chain traction devices are coaxially installed, driven and synchronously operated by the same power unit, and a total of two traction chains connect the lifting vehicle plate; after the spare anti-fall mechanism described in this embodiment is provided (two sets are provided for each lifting vehicle plate), when any traction chain breaks, the corresponding spare chain rope will replace the broken traction chain to tow the lifting vehicle plate to prevent the lifting vehicle plate from overturning and avoid safety accidents.

[0064] Embodiment 2

[0065] This embodiment is an improvement on the basis of the first embodiment, and the main difference from the first embodiment is that the traction device used in conjunction with the backup anti-fall mechanism in this embodiment is a circulating chain traction device driven by a power unit, which can prevent the lifting vehicle from falling during operation and avoid the safety hazards caused by the breakage of the traction chain in the circulating chain traction device; wherein the circulating chain traction device is a mature existing technology in the field, such as Figure 3-Figure 4 As shown, the driving sprocket 16 is fastened on the driving shaft driven by the output shaft of the motor reducer 19, and is driven to rotate by the motor reducer 19, and forms a closed-loop structure with the driving chain 12 and the passive sprocket 14; wherein, a hinge point is provided on the left side of the upper chain of the driving chain 12 (the left-hand side when facing the drawing), and a traction chain 13 is connected from the hinge point, and the traction chain 13 extends to the right, passes through the intermediate wheel 105 and then goes downward, and the end point is fastened to the lifting vehicle plate 03; a hinge point is provided on the right side of the lower chain of the driving chain 12 (the right-hand side when facing the drawing), and a traction chain 2 15 is connected from the hinge point, and the traction chain 2 15 extends to the left, passes through the intermediate wheel 206 and then goes downward, and the end point is fastened to the lifting vehicle plate 03.

[0066] like Figure 3 As shown, when the traction chain 13 and the traction chain 2 15 are both in good condition, the lifting vehicle plate 03 is in a balanced state; Figure 2 As shown, when the traction chain 13 breaks, the right end of the lifting vehicle plate 03 will lose traction, resulting in overturning, causing a major safety accident; similarly, when the traction chain 2 15 breaks, the left end of the lifting vehicle plate 03 will lose traction, resulting in overturning, causing a major safety accident.

[0067] like Figure 5-Figure 7As shown, in this embodiment, two spare chains are provided, namely spare chain 1 17 and spare chain 2 18; wherein, a hinge point is added on the left side of the upper chain of the driving chain 12 in the figure, and the spare chain 17 is connected from the hinge point. The spare chain 17 extends to the right, passes through the intermediate wheel 3 07 and then goes downward, and the end point is tightly connected to the lifting vehicle plate 03. The bypass direction of the spare chain 17 is the same as that of the traction chain 1 13; a hinge point is added on the right side of the lower chain of the driving chain 12 in the figure, and the spare chain 2 18 is connected from the hinge point. The spare chain 2 18 extends to the left, passes through the intermediate wheel 4 08 and then goes downward, and the end point is tightly connected to the lifting vehicle plate 03. The bypass direction of the spare chain 2 18 is the same as that of the traction chain 2 15.

[0068] like Figure 6 As shown, when the driving sprocket 16 rotates clockwise, the upper chain of the driving chain 12 moves to the right and the lower chain moves to the left, so that the lifting vehicle plate 03 moves downward; at this time, the traction chain 13 and the traction chain 2 15 are used for load-bearing traction, and the spare chain rope 1 17 and the spare chain rope 2 18 are used for follow-up displacement.

[0069] like Figure 7 As shown, when the traction chain 13 breaks, the right end of the lifting platform 03 loses the load-carrying traction of the traction chain 13, but is immediately pulled by the spare chain rope 17, thereby avoiding the occurrence of a capsizing accident. Similarly, when the traction chain 2 15 breaks, the left end of the lifting platform 03 loses the load-carrying traction of the traction chain 2 15, but is immediately pulled by the spare chain rope 2 18, thereby avoiding the occurrence of a capsizing accident.

[0070] In this embodiment, the spare chain rope 17 and the spare chain rope 2 18 can be chains or steel cables, and in actual application, the length of the spare chain rope 17 is greater than the length of the traction chain rope 13, and the length of the spare chain rope 2 18 is greater than the length of the traction chain rope 2 15, so that under normal circumstances, the traction chain bears the load of the lifting vehicle plate.

[0071] Furthermore, it needs to be explained that a set of circulating chain traction devices is respectively provided on the upper longitudinal beams on both sides of the longitudinal direction of each lifting vehicle plate of the simple lifting or lifting and transverse moving parking equipment using a circulating chain traction device. The power sprockets of the two sets of circulating chain traction devices are coaxially installed, driven and operated synchronously by the same power unit, and a total of four traction chains connect the lifting vehicle plate; after the spare anti-fall mechanism described in this embodiment is provided (two sets are provided for each lifting vehicle plate), when any traction chain breaks, the corresponding spare chain rope will replace the broken traction chain to tow the lifting vehicle plate to prevent the lifting vehicle plate from overturning and avoid safety accidents.

[0072] Embodiment 3

[0073] The present embodiment provides a synchronization mechanism, specifically a top-level clutch synchronization mechanism, which is arranged at the top of the parking equipment and can drive the traction device of the lifting vehicle plate of multiple parking spaces arranged in parallel on the top level; specifically, the top-level clutch synchronization mechanism mainly includes a power unit (preferably a motor reducer), a power transmission device, and a clutch synchronization detection device; the motor reducer is installed on the crossbeam of the outermost parking space among the multiple parking spaces arranged in parallel on the top level, and the crossbeam can be selected from the front crossbeam or the rear crossbeam; the power transmission device includes a driving shaft, a driving component, a passive component, and a driving clutch component; the driving component includes a driving gear, and the driving shaft The rotational power is obtained by directly connecting the output shaft of the motor reducer, or by driving an external speed change device through the motor reducer; the driving shaft horizontally spans multiple parking spaces and is arranged on the equipment frame through a bearing seat; the number of the driving gears is the same as the number of the parking spaces, and one is installed for each parking space; the number of the passive components is the same as the number of the lifting plates, and a set is installed for each lifting plate, including a passive gear; the installation position of the passive gear corresponds to the driving gear, and when the driving clutch component is in a driving engagement state, the driving gear drives the passive gear to rotate.

[0074] In this embodiment, the passive gear can be installed on the power sprocket mounting shaft of the endless chain traction device of the lifting vehicle plate; or, the passive gear is arranged on the equipment frame of the parking space through the mounting shaft and the bearing seat, and meshes with the gear of the power sprocket mounting shaft of the endless chain traction device installed on the lifting vehicle plate corresponding to the parking space.

[0075] In this embodiment, the number of the driving clutch components is the same as the number of the lifting vehicle plates, and each lifting vehicle plate is installed with a corresponding set, including a linear displacement driving unit and a gear clamp; the linear displacement driving unit is fastened on the equipment frame, and the direction of the linear displacement is the same as the axial direction of the driving shaft, driving the gear clamp to perform reciprocating linear motion, so that the driving gear of the active component and the passive gear of the passive component are switched between a fully engaged state and a disengaged state; the tooth shape of the driving gear and the passive gear on the side that contacts each other when the clutch state is switched is processed into a wedge shape or an arc shape that is conducive to engagement.

[0076] In this embodiment, the gear clamp clamps the active gear of the active component, or the gear clamp clamps the passive gear of the passive component.

[0077] In this embodiment, the synchronous detection device mainly includes a detection disk and a photoelectric detection unit; the detection disk is tightly mounted on the driving shaft, and has notches equally divided along the circumference with the same number of teeth as the driving gear; the photoelectric detection unit is arranged corresponding to the detection disk, and when the driving shaft rotates and drives the detection disk to rotate synchronously, the photoelectric detection unit detects the notches and sends out a jump signal of conduction or shielding.

[0078] Furthermore, if Figure 8 As shown, this embodiment is described in detail by taking the parking equipment having three top parking spaces as an example, wherein the three top parking spaces are top parking space 1 54, top parking space 2 55, and top parking space 3 56; wherein the top parking space 1 54 is equipped with two sets of circulating chain traction devices consisting of a driving sprocket a27, a driving shaft 28, a driving sprocket b29, a circulating chain b30, a passive sprocket b31, a passive sprocket a32, and a circulating chain a33; the top parking space 2 55 is equipped with two sets of circulating chain traction devices consisting of a driving sprocket a27, a driving shaft 28, a driving sprocket b29, a circulating chain b30, a passive sprocket b31, a passive sprocket a32, and a circulating chain a33; It is equipped with two sets of circulating chain traction devices consisting of a driving sprocket a37, a driving shaft a38, a driving sprocket b39, a circulating chain b40, a passive sprocket b41, a passive sprocket a42, and a circulating chain a43; the top parking space 56 is equipped with two sets of circulating chain traction devices consisting of a driving sprocket a47, a driving shaft a48, a driving sprocket b49, a circulating chain b50, a passive sprocket b51, a passive sprocket a52, and a circulating chain a53.

[0079] It needs to be further explained that the parking equipment of the utility model can adopt the bottom supporting chain traction device or the circulating chain traction device of the prior art as the traction system, and can also adopt the bottom supporting chain traction device in embodiment one to add the spare anti-fall mechanism as the traction system, and can also adopt the circulating chain traction device in embodiment two to add the spare anti-fall mechanism as the traction system.

[0080] In this embodiment, the top-level clutch synchronization mechanism is arranged in the top-level parking space 1 54, the top-level parking space 2 55, and the top-level parking space 3 56 area, and mainly includes a motor reducer 19, a gear 1 20, a gear 21, a driving shaft 22, and a detection disk 23; it also includes a gear clamp 1 24, a driving gear 1 25, a gear clamp 2 34, a driving gear 2 35, a gear clamp 3 44, and a driving gear 3 45; wherein, a gear 1 20 is fastened to the output shaft of the motor reducer 19; the gear 2 21 is fastened to the driving shaft The left end of the shaft 22 is meshed with the gear 1 20; the driving shaft 22 horizontally spans the top parking space 1 54, the top parking space 2 55, and the top parking space 3 56, and the right end is fastened with a detection disk 23; the detection disk 23 is processed with notches with the same number of teeth as the driving gear at equal intervals along the circumference, and cooperates with a photoelectric detection unit (not shown in the figure) to form a synchronous detection device; when the driving shaft 22 rotates and drives the detection disk 23 to rotate synchronously, the photoelectric detection unit detects the notch and sends a jump signal of conduction or shielding to the outside.

[0081] In this embodiment, the driving shaft 22 is installed with a driving gear 25 in a spline or flat key sliding fit manner at the position of the top parking space 54; the driving shaft 28 installed in the top parking space 54 is fastened with a passive gear 26 at the position corresponding to the driving gear 25; the driving gear 25 is clamped by the gear clamp 24, and can make reciprocating linear motion along the driving shaft 22 under the drive of the corresponding linear displacement drive unit (not shown in the figure), so that the driving gear 25 and the passive gear 26 can be switched between a fully meshed state and a disengaged state; when the driving gear 25 is engaged, the driven gear 26 is engaged with the driven gear 26, and the driven gear 26 is engaged with the driven gear 26. The wheel 25 is in a fully meshed state with the passive gear 26, and the rotation of the motor reducer 19 drives the gear 20, the gear 21 and the driving shaft 22 to rotate, and drives the driving shaft 28 to rotate through the driving gear 25 and the passive gear 26, thereby driving the two sets of circulating chain traction devices installed on the top parking space 54 to enter the running state; when the driving gear 25 and the passive gear 26 are out of mesh, the rotation of the motor reducer 19 cannot drive the passive gear 26 to rotate, and the two sets of circulating chain traction devices installed on the top parking space 54 are in a stopped running state.

[0082] Among them, the operation state of the circulating chain traction device of the top parking space 2 55 and the top parking space 3 56 is similar to the stop operation state, and will not be described in detail in this embodiment.

[0083] In this embodiment, the circulating chain traction devices of the top parking space 1 54, the top parking space 2 55, and the top parking space 3 56 are changed from the running state to the stopped running state by controlling the same type of signal (conduction or shielding) emitted by the same set of synchronous detection devices, and the tooth surfaces of the mutually meshing gears are processed into a wedge shape or arc shape that is conducive to meshing, thereby ensuring the smooth transition of the clutch state.

[0084] It should be noted that it is also feasible to install the synchronous detection device on the output shaft of the motor reducer. Since the structure and operating principle are the same as those of the above-mentioned detection device, they will not be described in detail in this embodiment.

[0085] Embodiment 4

[0086] This embodiment provides a synchronization mechanism, specifically a middle-layer clutch synchronization mechanism, which is arranged in the middle layer of the parking equipment, and the middle layer refers to the other layers except the ground layer and the top layer, and is provided with a transverse frame; the middle-layer clutch synchronization mechanism uses a motor reducer to respectively drive the circulating chain traction device of the lifting vehicle plate inside the transverse frame of multiple parking spaces arranged in parallel on the middle layer, and mainly includes a motor reducer, a power transmission device, and a clutch synchronization detection device; specifically,

[0087] The motor reducer is installed on the crossbeam of the outermost parking space among the multiple parking spaces arranged in parallel on the middle layer, and the crossbeam can be selected from the front crossbeam or the rear crossbeam; the power transmission device includes a driving shaft, an active component, a passive component, and a driving clutch component; the active component includes a driving gear, and the rotational power of the driving shaft is obtained by directly connecting to the output shaft of the motor reducer, or by driving an external speed change device through the motor reducer; the driving shaft horizontally spans multiple parking spaces and is arranged on the equipment frame through a bearing seat; the number of the driving gears is the same as the number of the parking spaces, and one is installed for each parking space; the number of the passive components is the same as the number of the lifting plates, and one set, including a passive gear, is installed for each lifting plate; the installation position of the passive gear corresponds to the driving gear, and when the driving clutch component is in a driving engagement state, the driving gear drives the passive gear to rotate.

[0088] In this embodiment, the passive gear is installed on the power sprocket mounting shaft of the endless chain traction device of the lifting vehicle plate; or, the passive gear is arranged on the transverse frame through the mounting shaft and the bearing seat, and meshes with the gear installed on the power sprocket mounting shaft of the endless chain traction device of the lifting vehicle plate corresponding to the transverse frame.

[0089] In this embodiment, the driving clutch component includes a linear displacement driving unit and a gear clamp, which are arranged in one of the following ways:

[0090] Mode 1: The number of the driving clutch components is the same as the number of the parking spaces, and one set is installed for each parking space. The gear clamp clamps the driving gear of the active component; the linear displacement drive unit is fastened on the equipment frame, and the direction of the linear displacement is the same as the axial direction of the driving shaft of the active component, driving the gear clamp to perform reciprocating linear motion, so that the driving gear of the active component and the passive gear of the passive component are switched between a fully meshed state and a disengaged state; the tooth profiles of the driving gear and the passive gear on the side that are in contact with each other when the clutch state is switched are processed into a wedge shape or an arc shape that is conducive to meshing;

[0091] Method 2: The number of the driving clutch components is the same as the number of the transverse shift frames, and one set is installed for each transverse shift frame. The gear clamp clamps the passive gear of the passive component; the linear displacement driving unit is fastened on the corresponding transverse shift frame, and the direction of the linear displacement is the same as the axial direction of the active shaft of the active component, driving the gear clamp to perform reciprocating linear motion, so that the active gear of the active component and the passive gear of the passive component are switched between a fully engaged state and a disengaged state; the tooth shape of the side of the active gear and the passive gear that are in contact with each other when the clutch state is switched is processed into a wedge shape or an arc shape that is conducive to engagement.

[0092] In this embodiment, the synchronous detection device includes a detection disk and a photoelectric detection unit; the detection disk is tightly mounted on the driving shaft and has notches equally divided along the circumference with the same number of teeth as the driving gear; the photoelectric detection unit is arranged corresponding to the detection disk, and when the driving shaft rotates and drives the detection disk to rotate synchronously, the photoelectric detection unit detects the notches and sends out a jump signal of conduction or shielding.

[0093] Furthermore, if Fig. 9 and Fig.10 As shown, this embodiment is described in detail by taking a parking facility having three intermediate parking spaces as an example, wherein the three intermediate parking spaces are intermediate parking space one 57 , intermediate parking space two 58 , and intermediate parking space three 59 .

[0094] It is common knowledge in the industry that the lifting platform of the middle layer is lifted and lowered by a circulating chain traction device installed on the transverse frame, and the transverse frame can move transversely on the middle layer; moreover, not all parking spaces on the middle layer are equipped with transverse frames.

[0095] like Fig. 9As shown, the current middle-layer parking space 1 57 is provided with a transverse frame 1 60, the middle-layer parking space 2 58 is provided with a transverse frame 2 61, and the middle-layer parking space 3 59 has no transverse frame; the transverse frame 1 60 is installed with two sets of circulating chain traction devices consisting of a driving sprocket 1 a27, a driving shaft 1 28, a driving sprocket 1 b29, a circulating chain 1 b30, a passive sprocket 1 b31, a passive sprocket 1 a32, and a circulating chain 1 a33; the transverse frame 2 61 is installed with two sets of circulating chain traction devices consisting of a driving sprocket 2 a37, a driving shaft 2 38, a driving sprocket 2 b39, a circulating chain 2 b40, a passive sprocket 2 b41, a passive sprocket 2 a42, and a circulating chain 2 a43. Among them, the above-mentioned circulating chain traction device can adopt the circulating chain traction device of the existing technology, and can also adopt the traction system with the backup anti-falling mechanism added.

[0096] In this embodiment, the middle-layer clutch synchronization mechanism is arranged in the middle-layer parking space 1 57, the middle-layer parking space 2 58, and the middle-layer parking space 3 59 area, and mainly includes a motor reducer 19, a gear 1 20, a gear 21, a driving shaft 22, and a detection disk 23; it also includes a gear clamp 1 24, a driving gear 1 25, a gear clamp 2 34, a driving gear 2 35, a gear clamp 3 44, and a driving gear 3 45; wherein, a gear 1 20 is fastened to the output shaft of the motor reducer 19, and a gear 2 21 is fastened to the main shaft. The left end of the driving shaft 22 is meshed with the gear 1 20; the driving shaft 22 horizontally spans the middle layer parking space 1 57, the middle layer parking space 2 58, and the middle layer parking space 3 59, and the right end is fastened with a detection disk 23. The detection disk 23 is processed with notches with the same number of teeth as the driving gear in equal parts along the circumference, and cooperates with a photoelectric detection unit (not shown in the figure) to form a synchronous detection device; when the driving shaft 22 rotates and drives the detection disk 23 to rotate synchronously, the photoelectric detection unit detects the notch and sends a jump signal of conduction or shielding to the outside.

[0097] In this embodiment, the driving shaft 22 is installed with a driving gear 25 in a spline or flat key sliding fit manner at the position of the middle layer parking space 1 57, and the driving gear 1 25 is clamped by a gear clamp 1 24, and can make reciprocating linear motion along the driving shaft 22 under the drive of the corresponding linear displacement drive unit (not shown in the figure); the driving shaft 22 is installed with a driving gear 2 35 in a spline or flat key sliding fit manner at the position of the middle layer parking space 2 58; the driving gear 2 35 is clamped by a gear clamp 2 34, and can make reciprocating linear motion along the driving shaft 22 under the drive of the corresponding linear displacement drive unit (not shown in the figure); the driving shaft 22 is installed with a driving gear 3 45 in a spline or flat key sliding fit manner at the position of the middle layer parking space 3 59; the driving gear 3 45 is clamped by a gear clamp 3 44, and can make reciprocating linear motion along the driving shaft 22 under the drive of the corresponding linear displacement drive unit (not shown in the figure).

[0098] like Fig. 9 As shown, the driving shaft 28 of the transverse frame 60 currently set in the middle-layer parking space 57 is fastened with a passive gear 26 at the position corresponding to the driving gear 25, and the driving gear 25 makes a reciprocating linear motion along the driving shaft 22 so that the driving gear 25 and the passive gear 26 are switched between a fully meshed state and a disengaged state; when the driving gear 25 and the passive gear 26 are in a fully meshed state, the motor reducer 19 rotates to drive the gear 20, the gear 21 and the driving shaft 22 to rotate, and drives the driving shaft 28 to rotate through the driving gear 25 and the passive gear 26, thereby driving the two sets of circulating chain traction devices of the transverse frame 60 currently located in the middle-layer parking space 57 to enter a running state; when the driving gear 25 and the passive gear 26 are in a disengaged state, the motor reducer 19 rotates and cannot drive the passive gear 26 to rotate, and the two sets of circulating chain traction devices of the transverse frame 60 currently located in the middle-layer parking space 57 are in a stopped state.

[0099] Similarly, the operating state and the stopped operating state of the circulating chain traction device of the second transverse frame 61 currently set in the second intermediate parking space 58 can be inferred, which will not be described in detail here.

[0100] In this embodiment, the circulating chain traction devices of transverse frame 1 60 and transverse frame 2 61 are changed from the running state to the stopped state by the same type of signal (conduction or shielding) emitted by the same set of synchronous detection devices, and the tooth surfaces of the mutually meshing gears are processed into a wedge or arc shape that is conducive to meshing, thereby ensuring the smooth transition of the clutch state.

[0101] like Fig.10 As shown, the second transverse movement frame 61 previously located at the second intermediate parking space 58 has been transversely moved to the third intermediate parking space 59, and the second intermediate parking space 58 no longer has a transverse movement frame.

[0102] The driving shaft 2 38 of the transverse frame 2 61 currently set in the middle-layer parking space 3 59 is fastened with the passive gear 2 36 at the position corresponding to the driving gear 3 45, and the driving gear 3 45 performs reciprocating linear motion along the driving shaft 22 so that the driving gear 3 45 and the passive gear 2 36 are switched between a fully meshed state and a disengaged state; when the driving gear 3 45 and the passive gear 2 36 are in a fully meshed state, the motor reducer 19 rotates to drive the gear 1 20, the gear 2 21 and the driving shaft 22 to rotate, and drives the driving shaft 2 38 to rotate through the driving gear 3 45 and the passive gear 2 36, thereby driving the two sets of circulating chain traction devices of the transverse frame 2 61 currently located in the middle-layer parking space 3 59 to enter the running state; when the driving gear 3 45 and the passive gear 2 36 are in a disengaged state, the rotation of the motor reducer 19 cannot drive the passive gear 2 36 to rotate, and the two sets of circulating chain traction devices of the transverse frame 2 61 currently located in the middle-layer parking space 3 59 are in a stopped running state.

[0103] Obviously, it is also feasible to install the synchronous detection device on the output shaft of the motor reducer. Since the structure and operating principle are the same as those described in this embodiment, they will not be described here.

[0104] It should be further explained that the photoelectric detection units of the top-layer clutch and synchronization mechanism and the middle-layer clutch and synchronization mechanism of the present invention can be discretely installed or directly installed using a slot-type photoelectric switch with a clamping detection disk.

[0105] The reason why there are differences in the structures of the top-layer clutch synchronization mechanism and the middle-layer clutch synchronization mechanism described in the utility model is that: each parking space on the top layer is correspondingly installed with a lifting vehicle plate, therefore, the number of active gears, passive gears and gear clamps in the driving clutch component is the same, which has nothing to do with whether the gear clamps clamp the active gear or the passive gear; while the lifting vehicle plate is installed in the middle layer through the transverse frame, and the number of transverse frames is equal to or less than the number of parking spaces; therefore, the number of passive gears in the driving clutch component is equal to or less than the number of active gears, and the number of gear clamps is related to whether the gear clamps clamp the active gear or the passive gear.

[0106] The application scenarios of the top-layer clutch synchronization mechanism and the middle-layer clutch synchronization mechanism described in the utility model are relatively special; first, it involves multiple sets of driving clutch components and corresponding active gears and passive gears; second, at most one set of active gears and passive gears can be in meshing state at the same time; third, the meshing and disengagement of each set of active gears and passive gears are realized in the state of stopping rotation. In order to ensure that the physical tooth profile and tooth groove are basically in a positive state when each set of active gears and passive gears are converted from the disengaged state to the meshed state (a small offset can be compensated by processing into a wedge-shaped or arc-shaped tooth shape), the utility model innovatively proposes a technical solution for a synchronous detection device, which only requires to determine in the running program that the photoelectric detection unit of the synchronous detection device is only allowed to be in the moment of shielding signal output or in the moment of conducting signal output to stop the rotation of the active shaft (because the motor is equipped with a brake device, it can ensure instant braking); and, by changing the size of the rotation angle occupied by the notch of the detection disk of the synchronous detection device, the allowable offset angle of the physical tooth profile and tooth groove during clutch can be changed.

[0107] It is common sense in the industry that at any one time, only one of the top and middle lift platforms can be raised or lowered. Therefore, the prerequisite for using the top-layer clutch synchronization mechanism or the middle-layer clutch synchronization mechanism is that the control system must ensure that at most only one pair of clutch mechanisms are in the engaged state at any one time, and the other clutch mechanisms must be in the separated state. Since the lift platform in the separated state has no traction power, it must be supported by the anti-fall hook when it is stationary on the layer. Obviously, the control process required for the above operation is different from the control process using the existing technology, but it is not difficult for those skilled in the art.

[0108] Embodiment 5

[0109] The present embodiment provides a transverse movement mechanism, which can be applied to the parking equipment used in conjunction with the backup anti-fall mechanism as described above, and mainly includes a transverse movement vehicle plate and a driving and positioning unit, wherein the ground layer is not provided with a load-bearing guide rail, and the bottom of the transverse movement vehicle plate is installed with at least three load-bearing rollers that are directly in contact with the ground, with a rotation axis parallel to the ground and perpendicular to the longitudinal center line of the vehicle plate, and can roll freely; the driving and positioning unit includes a positioning track, a rack, a motor reducer, a gear, and a positioning roller, the positioning track is fastened to the rear end of the ground parking space near the longitudinal edge line, spanning all ground parking spaces; the rack is fastened to the positioning track, and the motor reducer is fastened to the rear end of the transverse movement vehicle plate; the gear is meshed with the rack, obtains power from the motor reducer, and drives the transverse movement vehicle plate to move back and forth laterally; the positioning roller is arranged at the rear end of the vehicle plate, and the lateral displacement of the vehicle plate is positioned by clamping the positioning track.

[0110] In this embodiment, the gear and the corresponding rack installation position, the positioning roller and the corresponding positioning track cross section can be arranged in one of the following ways:

[0111] Method 1: the gear only provides driving and does not have positioning function, specifically:

[0112] The installation position of the rack is not limited; the number of the gear is at least one; when the number of the gear is one, the gear is fixedly mounted on the output shaft of the motor reducer; when the number of the gear is more than one, the power output of the motor reducer transmits power to the gear through a synchronous gear / synchronous belt or a sprocket / chain to achieve synchronous operation of multiple gears;

[0113] The positioning track is provided with two mutually parallel vertical surfaces as positioning reference surfaces; the number of the positioning rollers is at least two groups, and each group includes two positioning rollers that respectively clamp the two positioning reference surfaces of the positioning track;

[0114] Mode 2: In addition to providing drive, the gear also has a positioning function, specifically:

[0115] The tooth surface of the rack is perpendicular to the ground, and the number of the gears is at least two; the power output of the motor reducer transmits power to the gears through synchronous gears / synchronous belts or sprockets / chains to achieve synchronous operation of multiple gears;

[0116] The vertical surface of the positioning track parallel to the rack serves as a positioning reference surface; the number of the positioning rollers is the same as the number of the gears, and the positioning rollers clamp the positioning track together with the gears.

[0117] In this embodiment, in order to reduce the pressure of the load-bearing rollers on the ground and make the transverse vehicle plate have better load-bearing capacity, multiple load-bearing rollers can be set at appropriate positions of the transverse vehicle plate. Since the load-bearing guide rails are eliminated, the difficulty of entering and exiting the vehicle is significantly reduced.

[0118] In addition, since the meshing of gears and racks is a precise transmission, by installing an encoder or similar component on the gear, the displacement distance of the vehicle plate can be accurately determined, thereby simplifying the measures for detecting the in-place and out-of-limit detection of the lateral movement of the vehicle plate.

[0119] Furthermore, if Figure 11-13As shown, in this embodiment, two ground parking spaces are set up on the ground layer as an example for detailed description, and the two ground parking spaces are ground parking space one 62 and ground parking space two 63; the current ground parking space one 62 is provided with a transverse vehicle plate 70, and the ground layer is not provided with a load-bearing guide rail, and the transverse vehicle plate 70 is installed with 16 load-bearing rollers 69 that are directly in contact with the ground, with a rotation axis parallel to the ground and perpendicular to the longitudinal center line of the transverse vehicle plate 70, and can roll freely.

[0120] Moreover, the present embodiment adopts the aforementioned method 2 of "the gear not only provides drive, but also has a positioning function", specifically: the rack 65 is fastened to the ground through the channel steel 66 and the mounting base plate 64; the gears of the two sets of driving gear units 68 installed on both sides of the rear end of the transverse vehicle plate 70 are respectively meshed with the rack 65 (from the above, it can be seen that the power output of the motor reducer transmits power to the gear through the synchronous gear / synchronous belt or sprocket / chain to realize the synchronous operation of multiple gears); the side vertical surface of the rack 65 facing away from the tooth shape is used as the positioning reference surface (that is, the rack 65 is also used as a positioning track), and two sets of ball units 67 corresponding to the gears of the driving gear unit 68 are installed on the side close to the positioning reference surface; the positioning roller of the ball unit 67 and the gear of the driving gear unit 68 jointly clamp the rack 65 to realize the transverse positioning of the transverse vehicle plate 70.

[0121] Embodiment 6

[0122] In this embodiment, a parking device is provided, including a parking device body, which is a two-layer or three-layer parking device; wherein the parking device body includes a plurality of parking units arranged side by side, and the parking unit can be a two-parking unit including two flat parking spaces or a three-parking unit including three flat parking spaces.

[0123] In this embodiment, each of the parking units is provided with an operation box, a control system, and a safety detection alarm system, and can operate independently; wherein the operation box and the main control unit of the control system can be constructed in one of the following ways:

[0124] Mode 1: The operation box and the main control unit of the control system are separately established single chip microcomputers;

[0125] Mode 2: The main control unit of the operation box is a single chip microcomputer, and the main control unit of the control system is a PLC;

[0126] Mode 3: The operation box and the main control unit of the control system are the same single chip microcomputer.

[0127] In this embodiment, the safety detection alarm system includes a person and vehicle mistaken entry detection device arranged at the front end of the frame and connected to the control system signal, a vehicle overlength detection device arranged at the rear end of the frame, an emergency stop switch arranged near the operation box, and an audible and visual alarm device arranged near the operation box.

[0128] The button setting of the operation box in this embodiment is very simple. It only needs to set the selection button corresponding to the number of parking spaces, plus the confirmation button, cancel button, and completion button required for the operation; and the number of selection buttons is small. Even if it is a basic unit composed of three flat parking spaces, its selection buttons only need to be arranged three buttons each (a total of six, corresponding to six parking spaces) up and down. Moreover, the selection buttons are the same as the number of parking spaces, and the setting direction corresponds to the parking space position. This is an innovation for the prior art, which can not only cooperate with the setting of the parking unit of the utility model, but also make the user's parking and retrieval operation very simple and concrete, bringing great convenience to the user's operation. For example, when a user parks a car, he only needs to select an empty car board at random in the parking unit, and then find the corresponding selection button in the button area of ​​the operation box according to the parking space position of the empty car board, press it and then press confirmation, and the equipment control system will dispatch the empty car board to the ground floor so that the user can park the car; when a user picks up a car, he only needs to find his own vehicle on the parking unit, find the corresponding selection button in the button area of ​​the operation box according to the parking space position of the vehicle, press it and then press confirmation, and the equipment control system will dispatch the car board where the vehicle is located to the ground floor so that the user can pick up the car.

[0129] From the above, it can be seen that compared with the prior art practice in which users need to enter the vehicle plate number or swipe a card or enter the license plate number on the operation box to access the vehicle, the operation box of this embodiment is intuitive, simple and fast to operate.

[0130] In this embodiment, each parking unit is provided with a safety detection alarm system operation box, a control system, and a safety detection alarm system, and can operate independently. This is an innovation for the prior art and also provides more complete technical support for combining more than one basic unit into a set of equipment.

[0131] It should be further explained that the configuration of the safety detection alarm system is similar to the safety detection alarm system configured in a set of equipment in the current technology, and will not be described in detail here.

[0132] In this embodiment, the parking equipment body can be a two-story simple lifting type parking equipment, and each of the parking units includes the above-mentioned backup anti-fall mechanism; further, the two-story simple lifting type parking equipment also includes the above-mentioned top-level clutch synchronization mechanism.

[0133] In this embodiment, the parking equipment body can also be a two-story lifting and transverse moving parking equipment, and each of the parking units includes the above-mentioned backup anti-fall mechanism; further, the two-story lifting and transverse moving parking equipment also includes one of the above-mentioned top-layer clutch synchronization mechanism and the ground-layer transverse moving drive mechanism, or uses both mechanisms at the same time.

[0134] In this embodiment, the parking equipment body can also be a three-layer lifting and transverse moving parking equipment, and each of the parking units includes the above-mentioned backup anti-fall mechanism; further, the three-layer lifting and transverse moving parking equipment also includes one of the above-mentioned top-layer clutch synchronization mechanism, middle-layer clutch synchronization mechanism, and ground-layer transverse driving mechanism, or any multiple mechanisms are used at the same time.

[0135] Furthermore, if Fig.14 As shown, this embodiment is described in detail by taking a two-layer lifting and transverse moving parking equipment consisting of a three-parking unit (parking unit 1 90 located on the left side of the figure) and a two-parking unit (parking unit 2 91 located on the right side of the figure) as an example. The two parking units are respectively provided with an operating box, a control system, and a safety detection alarm system, and can operate independently.

[0136] In the present embodiment, an operation box 88 is provided corresponding to the parking unit 90. The operation box 88 is arranged opposite to the parking unit 90, so that the operator can easily and comprehensively observe all conditions of the parking unit 90, avoiding the potential safety hazard that the operator is difficult to comprehensively observe in the prior art; wherein, the operation box 88 is provided with six square buttons, the three square buttons in the upper row respectively correspond to the three second-floor parking spaces on the top floor (i.e., the second floor) of the three-parking unit, and the three square buttons in the lower row respectively correspond to the three ground parking spaces on the ground floor of the three-parking unit.

[0137] The parking unit 2 91 is provided with an operation box 2 89 corresponding to the parking unit 2 91. The operation box 2 89 is arranged opposite to the parking unit 2 91. The operator can easily and comprehensively observe all conditions of the parking unit 2 91, avoiding the potential safety hazard that the operator is difficult to comprehensively observe in the prior art; wherein, the operation box 2 89 is provided with four square buttons, the two square buttons in the upper row respectively correspond to the two second-floor parking spaces on the top floor (i.e., the second floor) of the two parking units, and the two square buttons in the lower row respectively correspond to the two ground parking spaces on the ground floor of the two parking units.

[0138] According to industry common sense, the two circular buttons set on these two operation boxes are one confirmation button (pressing any square button and then pressing this button means confirming the selected operation of the square button), and the other is a cancel button (pressing any square button and then pressing this button means giving up the selected operation of the square button). Of course, the buttons of the above operation boxes are set according to the simplest mode, and buttons with other functions can be appropriately added.

[0139] In this embodiment, the second-floor parking space one 74, the second-floor parking space two 75, the second-floor parking space three 76, the second-floor parking space four 77, and the second-floor parking space five 78 are respectively provided with a lifting plate one 79, a lifting plate two 80, a lifting plate three 81, a lifting plate four 82, and a lifting plate five 83; the ground parking space one 62 has no plate and is currently a lateral shift space; the ground parking space two 63, the ground parking space three 71, the ground parking space four 72, and the ground parking space five 73 are respectively provided with a lateral shift plate one 84, a lateral shift plate two 85, a lateral shift plate three 86, and a lateral shift plate four 87.

[0140] In the current state, if the leftmost square key in the lower row of the operation box 88 is selected, it is an invalid operation (the corresponding ground parking space 62 has no car plate); if the middle square key in the lower row of the operation box 88, the rightmost square key or any square key in the lower row of the operation box 89 is selected, it means selecting the car plate located above the corresponding ground parking space for parking storage and retrieval operations, and the control system does not need to perform car plate scheduling (if a secondary lateral shift function is provided, a secondary lateral shift operation of the lateral shift car plate is required), and only the lighting enhancement control and the operation warning device of the corresponding operation area need to be performed, indicating that there are parking storage and retrieval operations in the corresponding area.

[0141] In the current state, if the leftmost square key on the upper row of the operation box 88 is selected, it means that the corresponding second-floor parking space 74 is selected for parking and retrieval operations, and the control system of the parking unit 90 needs to dispatch the lifting plate 79 located at the second-floor parking space 74 to the ground parking space 62; if the middle square key, the rightmost square key or any square key on the upper row of the operation box 88 is selected, it means that the corresponding second-floor parking space is selected for parking and retrieval operations; because there are currently transverse plates under these lifting plates, the corresponding control system needs to first perform light enhancement control and operation warning devices in the operation area to indicate that there are parking and retrieval operations in the corresponding area, and then dispatch the corresponding transverse plate to form a suitable transverse space, and finally perform the descending operation of the corresponding lifting plate.

[0142] The above-mentioned operation control belongs to the prior art in this field and will not be described in detail here.

[0143] From the above, it can be seen that the unit combination method of the utility model is simple, intuitive, safe, reliable, and easy to standardize and serialize.
