Description

Technical Field

[0001] This utility model relates to the field of vertical circulation three-dimensional parking garages, specifically a vertical circulation anti-fall device. Background Technology

[0002] The booming development of the automotive industry and the continuous growth of car ownership have led to an increasing demand for parking lots. However, due to urban development constraints, traditional parking lots occupy a large area and have low efficiency. As a result, various mechanical parking garages have emerged, including lift-and-slide, simple lift, planar movement, and vertical circulation types. Among them, vertical circulation parking garages have the advantages of small footprint, relatively reasonable cost, and high vehicle storage and retrieval efficiency, and are increasingly widely used in the field of static traffic.

[0003] The vertical circulation parking system mainly consists of a drive system, a transmission system, a vehicle carrying system, a frame system, and a control system. The drive system uses a geared motor as the power source, which transmits the power to the vehicle carrying system through the transmission system. The transmission system uses a high-strength chain as the core traction component. Vehicle carrying brackets are installed on the chain at certain intervals. The chain rotates in a cycle under the drive of the geared motor, which drives the vehicle carrying brackets to achieve vertical circular movement. However, current transmission systems typically do not have anti-fall protection. When the number of cars parked on both sides of a vertical circulation parking garage is inconsistent, or the number of cars on both sides is the same but the weight of the cars is inconsistent—that is, when there is an off-center load, such as when one side is empty while the other side is full of cars, the off-center load reaches its maximum. If the motor drive chain breaks under off-center load, the heavily loaded side will drop rapidly under the action of gravity, which will have an unpredictable impact on the vehicles and the garage itself. In severe cases, a car may fall. Utility Model Content

[0004] The purpose of this invention is to provide a vertical circulating anti-fall device that can keep the slewing bearing turntable stationary by the relative clamping force of the wedges when the motor drive chain breaks, thereby preventing the basket and vehicle from rapidly descending or even falling, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vertical circulation fall arrest device, comprising a fall arrest device body located on a slewing bearing turntable, the fall arrest device body comprising a base, a connecting mechanism located on both sides of the slewing bearing turntable being installed at the upper end of the base, and wedges being slidably installed on the connecting mechanism, the extension lines of the moving directions of the wedges on both sides intersecting. A linkage mechanism for pulling the wedge block is installed on one side of the base. The linkage mechanism is driven by a pull electromagnet. The pull electromagnet is fixed to the base by a bracket, and an elastic reset component is provided between the linkage mechanism and the base.

[0006] Preferably, the base includes a support part and a connecting part, the support part and the connecting part form a U-shaped structure, the connecting mechanism is located at the upper middle part of the support part, and the corners of the support part are all arc corners.

[0007] Preferably, the connecting mechanism includes a guide seat and a sealing plate fixed to the upper end of the guide seat. The wedge is located between the guide seat and the sealing plate. The guide seat is provided with a notch for the wedge to move obliquely. The sealing plate is provided with a sliding hole. One end of the wedge is connected to the linkage mechanism through a connector, and the connector is located in the sliding hole.

[0008] Preferably, the side of the wedge block that contacts the slewing bearing turntable is integrally formed with multiple protrusions, and the side of the wedge block opposite to the protrusions is an inclined surface.

[0009] Preferably, a straight row of needle rollers is fixed on the side of the notch that contacts the inclined surface of the wedge, and the straight row of needle rollers is installed in the same direction as the inclined surface of the wedge.

[0010] Preferably, the straight needle roller includes a rectangular frame with multiple elongated holes equidistantly spaced on the rectangular frame. A roller is rotatably installed in each of the elongated holes, and the surface of the roller has a notched sidewall that contacts the inclined surface of the wedge.

[0011] Preferably, the linkage mechanism includes a connecting plate and a pull rod. The connecting plate is installed on the pulling end of the pull electromagnet, and both ends of the connecting plate are connected to the wedge block through the pull rod.

[0012] Preferably, the pull rod has an L-shaped structure, one end of the pull rod is integrally formed with a flange for connecting with the connecting plate, and the other end of the pull rod has a pin hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes the cooperation of a pull electromagnet, a linkage mechanism, and wedges. When the motor drive chain breaks, the pull electromagnet pulls the linkage mechanism, causing the linkage mechanism to move the wedges located on both sides of the slewing bearing. Since the extension lines of the wedge movement directions intersect, the distance between the two wedges will become smaller and smaller as the wedges move, meaning the friction between the wedges and the slewing bearing turntable will become larger and larger. The relative clamping force of the wedges keeps the slewing bearing turntable stationary, preventing the basket and vehicle from rapidly descending or even falling, thus achieving the effect of preventing vehicle fall.

[0016] 2. This utility model, through the cooperation of the elastic reset component and the linkage mechanism, enables the linkage mechanism to move in the opposite direction when the pull electromagnet is de-energized, thereby causing the linkage mechanism to drive the wedge block to return to its original position and automatically reset the wedge block.

[0017] 3. This utility model has a simple structure and reliable operation, and is suitable for use in vertical circulation mechanical garages. Attached Figure Description

[0026] Please see Figure 1-6 This utility model provides a technical solution: a vertical circulating fall arrestor, including a fall arrestor body 1 located on a slewing bearing turntable 10, such as... Figure 5 and Figure 6 As shown, the anti-fall device body 1 is located at the lower edge of the slewing bearing turntable 10. The anti-fall device body 1 is fixed to the support frame on which the slewing bearing turntable 10 is installed, and the anti-fall device body 1 is electrically connected to the self-owned control system of the vertical circulation parking garage. The control system mainly controls the operation of the transmission system, drive system, etc. through PLC to complete the control of vehicle parking and retrieval.

[0027] The anti-fall device body 1 includes a base 2. The upper end of the base 2 is equipped with a connecting mechanism 3 located on both sides of the slewing bearing turntable 10. A wedge 4 is slidably installed on the connecting mechanism 3. The extension lines of the moving directions of the two wedges 4 intersect, so that when the wedges 4 move, the distance between the two wedges 4 will become smaller and smaller, that is, the friction between the wedges 4 and the slewing bearing turntable 10 will become larger and larger. The relative clamping force of the wedges 4 keeps the slewing bearing turntable 10 stationary. A linkage mechanism 5 for pulling the wedge 4 is installed on one side of the base 2. The linkage mechanism 5 is driven by a pull electromagnet 6. The pull electromagnet 6 is fixed to the base 2 by a bracket 7. An elastic reset member is provided between the linkage mechanism 5 and the base 2. When the pull electromagnet 6 is de-energized, the elastic reset member drives the linkage mechanism 5 to move in the opposite direction, so that the linkage mechanism 5 drives the wedge 4 to return to its original position, thereby automatically resetting the wedge 4.

[0028] The base 2 includes a support part 21 and a connecting part 22. The support part 21 and the connecting part 22 form a U-shaped structure. The connecting mechanism 3 is located at the upper middle part of the support part 21. The corners of the support part 21 are all arc corners. The U-shaped structure allows the base 2 to be fitted onto the edge of the slewing bearing turntable 10, so that the connecting mechanism 3 is located on both sides of the slewing bearing turntable 10. The wedges 4 are installed on both sides of the slewing bearing turntable 10 through the connecting mechanism 3, so as to clamp and fix the slewing bearing turntable 10 by changing the size of the moving distance of the wedges 4 on both sides.

[0029] The connecting mechanism 3 includes a guide seat 31 and a sealing plate 32 fixed to the upper end of the guide seat 31. The wedge 4 is located between the guide seat 31 and the sealing plate 32. The guide seat 31 is provided with a notch 33 for the wedge 4 to move obliquely. The sealing plate 32 is provided with a sliding hole 34. One end of the wedge 4 is connected to the linkage mechanism 5 through a connector. The connector is located in the sliding hole 34. The pull electromagnet 6 is controlled by a PLC. When the pull electromagnet 6 is energized, it quickly retracts and pulls the linkage mechanism 5, causing the linkage mechanism 5 to drive the wedge 4 to move in the notch 33. The wedge 4 increases the friction between itself and the slewing bearing turntable 10 until the slewing bearing is completely stationary.

[0030] The wedge 4 has multiple protrusions 41 integrally formed on the side that contacts the slewing bearing turntable 10. The side of the wedge 4 opposite to the protrusions 41 is an inclined surface. The protrusions 41 are provided to increase the friction between the wedge 4 and the slewing bearing turntable 10, and the inclined surface is used to limit the movement direction of the wedge 4.

[0031] A straight row of needle rollers 9 is fixed on the side of the notch 33 that contacts the inclined surface of the wedge 4. The straight row of needle rollers 9 is installed in the same direction as the inclined surface of the wedge 4. The straight row of needle rollers 9 includes a rectangular frame 91. Multiple elongated holes are equally spaced on the rectangular frame 91. Rollers 92 are rotatably installed in the elongated holes. The surface of the rollers 92 contacts the inclined surface of the wedge 4 through the side wall of the notch 33. When the wedge 4 moves, the movement of the wedge 4 drives the rollers 92 to rotate within the rectangular frame 91, thereby reducing the friction between the wedge 4 and the guide seat 31 and improving the smoothness of the sliding of the wedge 4 within the guide seat 31.

[0032] The linkage mechanism 5 includes a connecting plate 51 and a pull rod 52. The connecting plate 51 is installed on the pulling end of the pull electromagnet 6. Both ends of the connecting plate 51 are connected to the wedge block 4 through the pull rod 52. The pull electromagnet 6 is a device that realizes linear traction action through electromagnetic principle. When the pull electromagnet 6 is energized, it rapidly contracts by using the magnetic attraction principle, causing the pull electromagnet 6 to drive the connecting plate 51 to pull the pull rod 52 to move, thereby realizing the instantaneous horizontal movement of the wedge block 4 until it contacts the surface of the vertical circulation top rotary support turntable 10.

[0033] The pull rod 52 has an L-shaped structure. One end of the pull rod 52 is integrally formed with a flange 53 for connecting with the connecting plate 51. The other end of the pull rod 52 has a pin hole 54. The connecting member is a pin. The pin passes through the pin hole 54 and the sliding hole 34 and connects to the upper surface of the wedge block 4, so that the wedge block 4 can change a certain angle around the pin as the axis during oblique movement, so that the wedge block 4 moves smoothly in the guide seat 31.

[0034] The bracket 7 has a U-shaped structure. The base of the pull electromagnet 6 is fixed in the middle of the bracket 7. Both ends of the bracket 7 are provided with folded edges 71 for connecting with the support part 21. Bolt holes 72 are provided on both the folded edges 71 and the support part 21. The bolt holes 72 facilitate the connection and fixation between the bracket 7 and the support part 21 by bolts, thereby improving the ease of installation of the bracket 7.

[0035] The elastic reset component is a tension spring 8. One end of the tension spring 8 is fixed to the middle of the connecting plate 51, and the other end of the tension spring 8 is fixed to the middle of the connecting part 22. The tension spring 8 is used to prevent the anti-fall device from being accidentally triggered during normal operation of the garage.

[0036] When the motor drive chain breaks, feedback is sent to the PLC via a proximity switch. The PLC controls the electromagnet to be energized quickly. After being energized, the pull electromagnet 6 quickly retracts, pulling the pull rod 52, thereby realizing the instantaneous horizontal movement of the wedge block 4 until it contacts the surface of the top slewing bearing turntable 10 of the vertical circulation system. Due to the eccentric load, the slewing bearing will rotate. At this time, the slewing bearing turntable 10 will contact the knurled wedge block 4. Under the action of the two wedge blocks 4, the slewing bearing turntable 10 will only rotate tighter and tighter until it comes to a complete stop, preventing the rapid descent of the eccentrically loaded basket and vehicle, thus achieving fall prevention. This utility model has a simple structure and reliable operation, and is suitable for use in vertical circulation mechanical garages.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
