A fall protection device and a parking installation

Abstract

This utility model provides a fall prevention device applied to parking equipment. The parking equipment includes a car carrier platform and uprights. The fall prevention device includes a mounting plate, a first rotating component, a second rotating component, and hanging posts. In this application, when the car carrier platform falls rapidly, the second rotating component first abuts against the upright. The second rotating component drives the first rotating component to rotate. Due to the rapid fall of the car carrier platform, the first rotating component has not yet had time to return to its initial position before abutting against the upright below. At this time, the second rotating component simultaneously abuts against the upright and the limiting component, thereby effectively preventing the car carrier platform from continuing to fall. Since several hanging posts are evenly spaced along the height direction of the upright, they always play a fall prevention role during the rising process of the parking platform, greatly improving the safety factor of the parking garage.

Description

Technical Field

[0001] This utility model relates to the field of parking garage technology, and in particular to a fall prevention device and parking equipment. Background Technology

[0002] Most existing mechanical parking systems have fall protection devices to prevent the parking platform from falling due to a sudden breakage of the drive chain or wire rope when it is in position.

[0003] Patent document with application number "CN202020784856.3" discloses a fall prevention and positioning device for parking equipment, including a bracket, a hook and a positioning plate installed below the transverse frame. The bracket is connected to the transverse frame, and the hook is hinged to the bracket via a pivot. A partition is provided in the positioning groove to cooperate with the hook. When the traction rope of the lifting mechanism breaks, the hook can hook the partition to prevent the parking plate from falling.

[0004] The aforementioned parking equipment's fall prevention and positioning device uses hooks to engage with partitions, preventing the parking platform from falling. Since the hooks are fixed to the transverse frame, their fall prevention function only becomes effective after the parking platform has risen to its designated position. While the parking platform is still rising, there is still a risk of falling, and the fixed hooks are ineffective in preventing this. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a fall prevention device applied to parking equipment. The parking equipment includes a car carrier plate 1 and a column 2. The fall prevention device includes a mounting plate 3, a first rotating component 4, a second rotating component 5, and a hanging column 6. The mounting plate 3 is located at the edge of the car carrier plate 1. The first rotating component 4 is rotatably connected to the mounting plate 3. The mounting plate 3 is provided with a limiting component 9. The first rotating component 4 is connected to a first restoring component 7. The first restoring component 7 is used to drive the first rotating component 4 to abut against the limiting component 9. The second rotating component 5 is rotatably connected to the first rotating component 4. The second rotating component 5 is connected to a second restoring component 8. The second restoring component 8 is used to drive the second rotating component 5 to abut against the first rotating component 4. A plurality of hanging columns 6 are provided, and the plurality of hanging columns 6 are evenly spaced along the height direction of the column 2. The hanging columns 6 are used to abut against the first rotating component 4 or the second rotating component 5.

[0026] According to some embodiments of the present invention, the first rotating component 4 includes a first vertical surface 41 and a first horizontal surface 42, the limiting component 9 includes a vertical limiting surface 91 and a horizontal limiting surface 92, the first restoring component 7 is used to drive the first vertical surface 41 to abut against the vertical limiting surface 91, the first vertical surface 41 is used to simultaneously abut against the hanging post 6 and the horizontal limiting surface 92 to fix the vehicle platform 1 on the hanging post 6, the second rotating component 5 includes a lower inclined surface 51, an upper inclined surface 52 and a second horizontal surface 53 that are sequentially adjacent, the second restoring component 8 is used to drive the second horizontal surface 53 to abut against the first horizontal surface 42, the upper inclined surface 52 is used to abut against the hanging post 6 during the upward displacement of the vehicle platform 1, and the lower inclined surface 51 is used to abut against the hanging post 6 during the downward displacement of the vehicle platform 1.

[0027] The specific working principle of this application will be described in detail below with reference to the above embodiments. Figure 2 When the vehicle platform 1 is stationary, the first rotating component 4, under the action of the first restoring component 7, has its first vertical surface 41 abutting against the vertical limiting surface 91; the second rotating component 5, under the action of the second restoring component 8, has its second horizontal surface 53 abutting against the first horizontal surface 42. (Refer to...) Figure 3When the vehicle platform 1 moves upward, the upper inclined surface 52 abuts against the lower half of the hanging post 6, the second rotating component 5 rotates downward, and the second horizontal surface 53 separates from the first horizontal surface 42, while the first rotating component 4 remains stationary. When the second rotating component 5 passes the hanging post 6, under the action of the second restoring component 8, the second horizontal surface 53 abuts against the first horizontal surface 42 again. (Refer to...) Figure 4 When the vehicle platform 1 moves downward, the lower inclined surface 51 abuts against the upper half of the hanging post 6, and the second rotating component 5 rotates upward, simultaneously causing the first rotating component 4 to rotate upward. When the second rotating component 5 passes the hanging post 6, under the action of the first restoring component 7, the first vertical surface 41 abuts against the vertical limiting surface 91 again. (Refer to...) Figure 5 When the vehicle platform 1 falls rapidly, the lower inclined surface 51 abuts against the upper half of the hanging post 6, and the second rotating component 5 rotates upward, simultaneously causing the first rotating component 4 to rotate upward. However, due to the excessive speed at which the vehicle platform 1 falls, the first rotating component 4 does not have time to return to its initial position and is immediately blocked by the next hanging post 6. This causes one end of the first vertical surface 41 to abut against the upper half of the hanging post 6, while the other end abuts against the horizontal limiting surface 92 (i.e., the first vertical surface 41 abuts against both the hanging post 6 and the horizontal limiting surface 92). At this point, the vehicle platform 1 cannot move, thus stopping its fall and greatly improving the safety factor.

[0028] Since several hanging posts 6 are evenly spaced along the height direction of the column 2, they always play a role in preventing falls during the process of the parking platform rising, greatly improving the safety factor of the parking garage.

[0029] According to some embodiments of this utility model, a first arc-shaped surface 54 is provided between the lower inclined surface 51 and the second horizontal surface 53. In this embodiment, the first arc-shaped surface 54 is provided so that the second rotating member 5 will not affect the first rotating member 4 when it rotates downward.

[0030] According to some embodiments of this utility model, the second rotating component 5 is provided with a receiving groove 43, which is used to accommodate the first rotating component 4. A second arc-shaped surface 44 adapted to the first arc-shaped surface 54 is formed within the receiving groove 43. In this embodiment, the cooperation between the first arc-shaped surface 54 and the second arc-shaped surface 44 makes the structure of the first rotating component 4 and the second rotating component 5 more compact and has a higher degree of fit.

[0031] According to some embodiments of the present invention, the rotation axes of the first rotating component 4 and the second rotating component 5 coincide, thereby making the structure between the first rotating component 4 and the second rotating component 5 more compact.

[0032] According to some embodiments of this utility model, the first restoring component 7 is a first torsion spring, one end of which is connected to the mounting plate 3, and the other end is connected to the first rotating component 4. Specifically, when the first rotating component 4 rotates upward, the torsion angle of the first torsion spring increases, thereby generating a restoring force. When the first rotating component 4 separates from the hanging post 6, under the restoring action of the first torsion spring, the first rotating component 4 returns to its initial position.

[0033] According to some embodiments of this utility model, the second restoring element 8 is a second torsion spring, one end of which is connected to the second rotating element 5, and the other end is connected to the first rotating element 4. Specifically, when the second rotating element 5 rotates upward, the torsion angle of the second torsion spring increases, thereby generating a restoring force. When the second rotating element 5 separates from the hanging post 6, under the restoring action of the second torsion spring, the second rotating element 5 returns to its initial position.

[0034] According to some embodiments of this utility model, the limiting member 9 is arranged vertically, and the mounting plate 3 is provided with a first reinforcing plate 93 extending horizontally, the first reinforcing plate 93 being connected to the lower part of the limiting member 9. In this embodiment, the connection strength of the limiting member 9 is improved by the first reinforcing plate 93.

[0035] According to some embodiments of this utility model, the mounting plate 3 is provided with a second reinforcing plate 31, which is connected to the vehicle-mounted plate 1. In this embodiment, the second reinforcing plate 31 improves the connection strength between the mounting plate 3 and the vehicle-mounted plate 1.

[0036] This utility model also provides a parking device, including a fall prevention device as described in any of the above claims.
