Description

Technical Field

[0001] This utility model relates to the field of automated parking system technology, and in particular to a locking device. Background Technology

[0002] As an important facility for solving urban parking difficulties, multi-level parking garages rely on their core equipment, the elevator, which needs to be frequently started and stopped and precisely positioned to different vehicle platforms during operation. To ensure the safety of the elevator during operation and its stability when stopped, and to prevent it from accidentally moving or falling before reaching the designated position, a locking device becomes a key component of the elevator's safety system, thus requiring a suitable locking device.

[0003] Some existing locking devices have problems such as complex structure, insufficient response, reliance on electric drive, risk of failure due to power outage, or easy jamming and difficulty in resetting after long-term use, which affect the reliability and maintenance convenience of the system. In addition, some locking devices occupy a large space and are not easy to integrate into the space-constrained pallet or frame structure of the automated parking system, which affects the flexibility of equipment layout. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a locking device that more precisely solves the issues of complex structure, high cost, and poor equipment layout flexibility of existing locking devices.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a locking device, including a first mounting plate, a second mounting plate fixedly connected to the side wall of the first mounting plate, and a locking component provided on the side walls of the first mounting plate and the second mounting plate. The locking component is used to lock and limit the vehicle platform and the comb frame.

[0007] Furthermore, both the first mounting plate and the second mounting plate have an L-shaped cross-section, and connecting bolts are installed between the first mounting plate and the second mounting plate, while two sets of fixing bolts are installed inside the second mounting plate.

[0008] Furthermore, the locking assembly includes a first limiting cover and a second limiting cover. The first limiting cover is bolted to the side wall of the first mounting plate, and the second limiting cover is bolted to the side wall of the second mounting plate. A rotating shaft is rotatably installed inside the first limiting cover and the second limiting cover.

[0009] Furthermore, a first connecting rod is sleeved and installed on one end of the rotating shaft. A limit opening is formed on the end surface of the first connecting rod. A limit post is provided in the limit opening. A blocking rod is installed at the end of the limit post. A bearing is slidably sleeved and installed on the outside of the blocking rod.

[0010] Furthermore, the first connecting rod is inclined and located on one side of the first limiting cover, and the bearing is connected to the first mounting plate by bolts.

[0011] Furthermore, a second connecting rod is sleeved and installed on the other end of the rotating shaft, and a crank is welded to the end of the side wall of the second connecting rod.

[0012] Furthermore, the second connecting rod is inclined, and the second connecting rod is fixed together with the first connecting rod by a pivot, and the crank is hollow.

[0013] Furthermore, a first limiting bolt is installed inside the second connecting rod, a second limiting bolt is installed between the first mounting plate and the second mounting plate, and a tension spring is provided between the first limiting bolt and the second limiting bolt, the tension spring being inclined.

[0014] The beneficial effects of this utility model are:

[0015] The present invention proposes a locking device that, with the arrangement of a first limiting cover, a second limiting cover, a rotating shaft, a first connecting rod, a limiting port, a limiting post, a blocking rod, a bearing, a second connecting rod, a crank rod, a first limiting bolt, a second limiting bolt, and a tension spring, can prevent the vehicle platform or comb frame from sliding off and falling from the parking space track, thus locking the vehicle platform or comb frame. The lever-type rotation design of the crank rod significantly reduces the space occupied by the device in the horizontal direction, and the rotation of the crank rod can complete a large displacement conversion within a limited space, making the entire locking structure more compact and small, and easier to integrate into the space-constrained tray or frame structure of the automated parking system, thus improving the flexibility of equipment layout.

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0023] Please refer to Figures 1-4 This utility model proposes a locking device, characterized in that it includes a first mounting plate 1, a second mounting plate 2 fixedly connected to the side wall of the first mounting plate 1, the second mounting plate 2 being fixedly connected to the side wall of the first mounting plate 1 by welding, and locking components provided on the side walls of the first mounting plate 1 and the second mounting plate 2. The locking components are used to lock and limit the vehicle platform and the comb frame. The cross-section of the first mounting plate 1 and the second mounting plate 2 is L-shaped. A connecting bolt 3 is installed between the first mounting plate 1 and the second mounting plate 2. Two sets of fixing bolts 4 are installed inside the second mounting plate 2. The connecting bolt 3 can be used to tighten the connection between the first mounting plate 1 and the second mounting plate 2. The fixing bolts 4 can be used to connect and fix the second mounting plate 2, the first mounting plate 1 and the steel frame of the three-dimensional parking garage together, so that the subsequent barrier bar 11 can lock the vehicle platform or the comb frame.

[0024] The locking assembly includes a first limiting cover 5 and a second limiting cover 6. The first limiting cover 5 is bolted to the side wall of the first mounting plate 1, and the second limiting cover 6 is bolted to the side wall of the second mounting plate 2. These components limit the rotation of the rotating shaft 7, ensuring the rotation of the first connecting rod 8 and the second connecting rod 13. The rotating shaft 7 is rotatably installed inside the first limiting cover 5 and the second limiting cover 6. A first connecting rod 8 is sleeved on the outside of one end of the rotating shaft 7. A limiting opening 9 is provided on the end surface of the first connecting rod 8 to limit the movement of the limiting post 10, thereby ensuring that the limiting post 10 drives the first connecting rod 8 to move. A limiting post 10 is provided inside the limiting opening 9, and a blocking bar 11 is installed at the end of the limiting post 10 for locking the vehicle platform or comb frame. The barrier bar 11 is externally slidably fitted with a bearing 12 for limiting the movement of the barrier bar 11 and ensuring its vertical movement. The first connecting rod 8 is inclined and located on one side of the first limiting cover 5. The bearing 12 is bolted to the first mounting plate 1. The other end of the rotating shaft 7 is externally fitted with a second connecting rod 13. A crank 14 is welded to the side wall end of the second connecting rod 13 for rotating the crank 14. The second connecting rod 13 is inclined and is fixed to the first connecting rod 8 via the rotating shaft 7. The crank 14 is hollow, and a first limiting bolt 15 is installed inside the second connecting rod 13. The first mounting plate 1 and the second mounting plate 2 are connected. A second limiting bolt 16 is installed between the first limiting bolt 15 and the second limiting bolt 16 to limit the tension spring 17. A tension spring 17 is installed between the first limiting bolt 15 and the second limiting bolt 16 to drive the crank rod 14 to reset. The tension spring 17 is inclined. When the elevator rises to the designated parking space, the pushing device in the tray applies a pushing force to the crank rod 14, causing it to rotate. The rotation of the crank rod 14 causes the second connecting rod 13 to rotate and the pull ring to stretch. Under the limiting of the rotating shaft 7, the first limiting cover 5, and the second limiting cover 6, the rotation of the second connecting rod 13 causes the first connecting rod 8 to rotate. Under the limiting of the limiting port 9, the rotation of the first connecting rod 8 causes the limiting post 10 to move downwards. The downward movement of the limiting post 10 causes the blocking bar 11 to retract, thus opening the locking device. At this point, the car carrier or comb frame can slide out of the parking space track. Once the car carrier or comb frame has been transported to the designated position, the thrust device releases its thrust. Under the reset force of the tension spring 17, the crank 14, the first connecting rod 8, the second connecting rod 13, and the blocking rod 11 reset. The extension of the blocking rod 11 prevents the car carrier or comb frame from sliding out of the parking space track and falling, thus locking the car carrier or comb frame. The lever-type rotation design of the crank 14 significantly reduces the horizontal space occupied by the device. The rotation of the crank 14 can complete a large displacement conversion within a limited space, making the entire locking structure more compact and smaller, and easier to integrate into the space-constrained tray or frame structure of the automated parking system. This improves the flexibility of the equipment layout and reduces the probability of jamming.It is particularly suitable for the harsh working environment of multi-level parking garages, characterized by high frequency and heavy loads.

[0025] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
