DETAILED DESCRIPTION

[0026] In order to make those skilled in the art better understand the technical scheme of the utility model, the utility model will be further introduced in detail below in conjunction with the drawings.

[0027] The utility model provides a kind of mechanical parking equipment chain break protection device as shown in Figures 1-5 Chain 1 is vertically arranged in annular shape, and shell 2 is arranged on one side of chain 1, which provides a relatively closed protection space for trigger mechanism 3 and brake mechanism 4, can prevent dust, sundries and the like from entering the inside of the device, avoid damaging internal parts, prolong the service life of the device;

[0028] Trigger mechanism 3 is arranged inside shell 2, and trigger mechanism 3 comprises:

[0029] Gear 31 is arranged inside shell 2, and rotating disc 32 is arranged on the front surface of gear 31, which ensures that signal disc 33 can stably rotate with the rotation of gear 31, and guarantees the accuracy of signal transmission. Signal disc 33 is embedded and installed on the front surface of rotating disc 32, and the signal generated by the rotation of signal disc 33 can be detected by rotating speed sensor 34. Signal disc 33 converts the rotating speed information of chain 1 into electrical signal, which provides basis for rotating speed sensor 34 to judge the state of chain 1, and rotating speed sensor 34 is horizontally fixedly installed on the front surface of shell 2, the front end of rotating speed sensor 34 is located inside shell 2, and corresponds to signal disc 33, rotating speed sensor 34 can monitor the rotating speed of signal disc 33 in real time, when chain 1 breaks or loosens to cause abnormal rotating speed, rotating speed sensor 34 can quickly detect such change, and transmit signal to controller, and controller receives signal, and immediately starts electric push rod 44, to trigger spring rod 42 and locking seat 41 in brake mechanism 4;

[0030] In this example, chain 1, arranged vertically in a loop shape, is a key component for power transmission in the mechanical parking equipment. It is connected to the drive unit of the parking equipment, and through chain transmission, it enables the lifting, lowering, and lateral movement of the vehicle platform, thereby completing the vehicle storage and retrieval operation. The normal movement of chain 1 drives the gear 31 that it meshes with, providing the basis for the operation of the trigger mechanism 3. If chain 1 breaks or becomes loose, its movement state will change, triggering the subsequent protection mechanism.

[0031] A braking mechanism 4 is provided inside the housing 2. The braking mechanism 4 includes:

[0032] Two locking seats 41 are respectively located above and below the gear 31 and are symmetrically distributed. A spring rod 42 is horizontally fixedly installed at the tail end of each locking seat 41. An electric push rod 44 is vertically fixedly installed above and below the outer side of the tail end of the spring rod 42 in the housing 2.

[0033] Furthermore, in the above technical solution, through holes 21 are provided at corresponding positions on the top and bottom of one side of the housing 2, and one side of the connecting strip 22 vertically penetrates the two through holes 21 of the housing 2. Guide grooves 24 are provided at the top and bottom of the housing 2.

[0034] In this example, the guide groove 24 provides a sliding track for the roller 46 on the locking seat 41, making the locking seat 41 move more smoothly and accurately. Meanwhile, the rubber plate 25 fixedly installed inside the housing 2 on the side away from the guide hole 23 acts as a buffer when the locking seat 41 moves to its limit position, reducing collisions and impacts between components, lowering noise, and protecting the components. The gear 31 meshes with the chain 1; the movement of the chain 1 drives the gear 31 to rotate synchronously, transmitting the movement status of the chain 1 to subsequent components. The rotation of the gear 31 drives the turntable 32 on its front to rotate, providing power for the rotation of the signal disc 33, enabling the signal disc 33 to reflect the rotational speed of the chain 1.

[0035] Furthermore, in the above technical solution, guide holes 23 are provided on the upper and lower sides of one side of the housing 2, a rubber plate 25 is fixedly installed on the side of the housing 2 away from the guide holes 23, and connecting strips 22 are fixedly installed on the top and bottom of the housing 2.

[0036] Furthermore, in the above technical solution, rollers 46 are rotatably mounted on opposite ends of the two locking seats 41. The two rollers 46 slide in the guide grooves 24 at the top and bottom of the housing 2, respectively. The front end of the locking seat 41 is a semi-ratchet structure, and the front end of the locking seat 41 is adapted to the chain 1.

[0037] In this example, when the locking seat 41 receives a braking signal, it moves towards the chain 1. Its semi-ratchet structure quickly locks the chain 1, preventing it from continuing to move, thus achieving braking protection for the parking equipment. The roller 46 slides within the guide groove 24, making the locking seat 41 move more smoothly and flexibly, reducing friction and wear, and improving braking reliability and response speed.

[0038] Furthermore, in the above technical solution, the tail ends of both spring rods 42 pass through the guide hole 23 and are located outside the housing 2. The opposite sides of the tail ends of the two spring rods 42 are provided with notches 43. The output end of the electric push rod 44 is fixedly installed with a wedge block 45. The wedge block 45 is adapted to the notch 43 and is inserted into it.

[0039] In this example, the electric push rod 44 is the power source for the braking mechanism. When the speed sensor 34 detects an abnormality in the chain 1 and sends a signal, the control system activates the electric push rod 44. When the electric push rod 44 pulls the wedge block 45 out of the notch 43 at the end of the spring rod 42, the spring rod 42 resets, and then the spring rod 42 can transmit the thrust to the locking seat 41, causing the locking seat 41 to move forward rapidly in an instant.

[0040] Furthermore, in the above technical solution, the two ends of the gear 31 are rotatably connected to the bearings on both sides of the inner wall of the housing 2 through the shaft, the front teeth of the gear 31 are adapted to and mesh with one side of the chain 1, and the turntable 32 is fixedly sleeved on the shaft on the front of the gear 31 by bolts.

[0041] The mechanical parking equipment chain breakage protection device provided by this utility model operates as follows:

[0042] After the mechanical parking equipment is started, the chain 1 begins to move under the drive of the drive device, realizing the lifting, lateral movement and other actions of the vehicle platform, and completing the vehicle storage and retrieval operation. The movement of the chain 1 drives the gear 31 meshing with it to rotate synchronously, and the gear 31 rotates stably on the bearings on both sides of the inner wall of the housing 2 through the shaft.

[0043] The rotation of gear 31 drives the turntable 32, which is bolted to its front, to rotate. Turntable 32 ensures the stable rotation of signal disc 33. The signal generated by the rotation of signal disc 33 is monitored in real time by speed sensor 34. Speed ​​sensor 34 converts normal speed information into an electrical signal and transmits it to the controller. At this time, the controller determines that chain 1 is in normal operating condition and does not trigger braking mechanism 4.

[0044] When chain 1 breaks or becomes loose, its motion changes, and its rotational speed also changes abnormally. This change in chain speed is transmitted to signal disk 33 via gear 31 and turntable 32. Speed ​​sensor 34 quickly detects the abnormal change in signal disk 33's speed and promptly transmits this abnormal signal to the controller. Upon receiving the abnormal signal from speed sensor 34, the controller immediately activates electric push rod 44. Electric push rod 44 pulls wedge block 45 out of recess 43 at the end of spring rod 42. Spring rod 42 resets, transmitting thrust to locking seat 41. Because roller 46 at the opposite end of locking seat 41 slides within guide groove 24, locking seat 41 moves smoothly, flexibly, and quickly towards chain 1 under the guidance of guide groove 24. The semi-ratchet structure at the front of the two locking seats 41 quickly locks chain 1, preventing further movement and thus providing braking protection for the parking equipment. This prevents accidents caused by chain abnormalities and ensures the safety of the equipment and vehicle.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
