Abstract
Description
Technical Field
[0001] This utility model relates to the field of parking equipment technology, specifically a lifting parking device with multiple safety protection devices. Background Technology
[0002] With the increase in urban vehicles, the resulting parking difficulties urgently need to be addressed. Modern cities mostly use multi-level parking garages to alleviate this problem. These garages typically have upper and lower parking platforms for separate vehicle parking. While multi-level parking garages can better utilize space and provide more parking spaces within the same footprint, their supporting frame is generally a single-column structure. The lifting mechanism of the upper parking system is located on a single column, requiring the installation of fixing ropes between the wall and the column to secure it and strengthen the structure. This results in inadequate safety protection for traditional lifting parking systems. Therefore, improving the safety protection of parking equipment is particularly important. Utility Model Content
[0003] This utility model provides a lifting parking device with multiple safety protection devices, which overcomes the shortcomings described in the background art.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A lifting parking device with multiple safety protection devices includes a left column, a right column, support legs, a frame beam, a vehicle carrier frame, and a vehicle carrier plate. Support legs are installed at the bottom of the left and right columns, and the left column forms the frame structure of the lifting parking device with the right column through the frame beam. The vehicle carrier frame is slidably installed between the left and right columns in the vertical direction. After the vehicle carrier frame is moved to a preset height, the safety anti-fall devices at both ends of the vehicle carrier frame are connected to the corresponding columns. The vehicle carrier frame moves up and down controlled by a lifting cylinder. A vehicle carrier plate for carrying cars is installed on the vehicle carrier frame. At least two protective chains are installed in the left and right columns. One chain is laid from the top of the left column downwards and extends along the bottom of the vehicle carrier plate to the bottom of the right column, and the other chain is laid from the top of the right column downwards and extends along the bottom of the vehicle carrier plate to the bottom of the left column. By laying a protective chain around the bottom of the vehicle platform, the vehicle platform is protected and prevented from falling, thus forming a first layer of protection for the lifting parking device in this utility model.
[0006] A preferred technical solution: Rollers are installed on the vehicle carrier frame, and the rollers roll along the inner walls of the left and right uprights. Specifically, two vehicle carrier frames can be installed, one to cooperate with the left upright and one to cooperate with the right upright. Two rollers are installed on each vehicle carrier frame, and the rollers are mounted via corresponding axles. To prevent the rollers from assisting the vehicle carrier frame in stable rolling, corresponding rolling grooves are usually provided on the corresponding uprights.
[0007] A preferred technical solution: The lifting cylinder is installed vertically, with its top end being a movable end. The movable end of the lifting cylinder controls the vertical displacement of the vehicle platform. The lifting cylinder controls the stable displacement of the hydraulic rod inside the cylinder by transferring hydraulic oil. Because the movement is smooth, the vehicle platform is not easily shaken during displacement. When the lifting cylinder is in the lifting state, the hydraulic rod is in a relatively stable state. Unless the lifting cylinder is controlled to retract the hydraulic rod, the lifting cylinder can always maintain a supporting state for the vehicle platform, constituting a first layer of protection for the lifting parking device of this utility model.
[0008] A preferred technical solution: A support roller is installed on the movable end of the lifting cylinder, and a lifting chain is connected to the back side of the vehicle frame. The lifting chain, support roller, and lifting cylinder work together to control the vertical displacement of the vehicle frame. At least one support roller is installed at the top of the hydraulic rod. The support roller can be a toothed wheel structure, and the lifting chain can be replaced with other chain structures depending on the selection of the support roller. The principle is that the hydraulic rod of the lifting cylinder controls the upward movement of the support roller, which drives the lifting chain to pull the vehicle frame to move vertically.
[0009] A preferred technical solution: The laying direction of the protective chain is adjusted by cooperating with the sprocket. That is, the laying direction of the protective chain is adjusted by winding the protective chain around the sprocket. Several protective chains can be set inside the column and at the bottom of the vehicle platform as needed, so that at least one chain is laid from the top of the left column downward and extends along the bottom of the vehicle platform to the bottom of the right column, and at least one chain is laid from the top of the right column downward and extends along the bottom of the vehicle platform to the bottom of the left column.
[0010] A preferred technical solution: The safety anti-fall device includes an anti-fall hook, a linkage rod, and a micro switch. The top of the anti-fall hook is mounted on the vehicle frame via a rotating rod. The micro switch controls the anti-fall hook to move out of or retract into the vehicle frame with the rotating rod as the rotation base point through the linkage rod. The safety anti-fall device constitutes a first layer of protection for the lifting parking equipment of this utility model.
[0011] A preferred technical solution: The left and right columns are provided with grooves for connecting and engaging anti-fall hooks.
[0012] A preferred technical solution: Install brackets on the left and right columns, and set up control panels on the brackets.
[0013] A preferred technical solution: The outriggers are divided into front outriggers and rear outriggers, which together with the column form a T-shaped structure.
[0014] A preferred technical solution includes a photoelectric sensor, which triggers a micro switch to start.
[0015] By adopting the above technical solution, the beneficial effects of this utility model are:
[0016] 1. The lifting parking equipment of this utility model is equipped with a lifting cylinder, a protective chain, a safety anti-fall device and other structures to form a safety protection device for the car platform, which prevents the car platform from shaking and falling. Even if one structure fails, the other structures can still play a safety protection role, effectively improving the safety of the lifting parking equipment and providing good comprehensive protection.
[0017] 2. The lifting parking equipment of this utility model has a simple structure and lower operating cost; due to its simple structure, it is easier to repair even if a malfunction occurs. Attached Figure Description

[0027] like Figures 1-6As shown, a lifting parking device with multiple safety protection devices includes a left column 1, a right column 2, support legs 3, a frame beam 4, a car carrier frame 5, and a car carrier plate 6. Support legs 3 are installed at the bottom of the left column 1 and the right column 2. The left column 1 and the right column 2 form the frame structure of the lifting parking device through the frame beam 4. The car carrier frame 5 is slidably installed between the left column 1 and the right column 2 in the vertical direction. After the car carrier frame 5 is moved to a preset height, the safety anti-fall devices 7 at both ends of the car carrier frame 5 are connected to the corresponding columns. The car carrier frame 5 is controlled to move up and down by a lifting cylinder 8. The car carrier plate 6 for carrying cars is installed on the car carrier frame 5. At least two protective chains 9 are provided in the left column 1 and the right column 2. One chain is laid down from the top of the left column 1 and extends along the bottom of the car carrier plate 6 to the bottom of the right column 2. The other chain is laid down from the top of the right column 2 and extends along the bottom of the car carrier plate 6 to the bottom of the left column 1. The protective chain 9 is laid around the bottom of the vehicle platform 6 to provide safety protection for the vehicle platform 6 and prevent it from falling, thus forming a first layer of protection for the lifting parking device in this utility model.
[0028] Furthermore, rollers 51 are installed on the vehicle frame 5, and the rollers 51 roll along the inner walls of the left column 1 and the right column 2. Specifically, two vehicle frames 5 can be provided, one cooperating with the left column 1 and the other with the right column 2. Two rollers 51 are installed on each vehicle frame 5, and the rollers 51 are mounted via corresponding axles. To prevent the rollers 51 from assisting the vehicle frame 5 in stable rolling, rolling grooves adapted to them are usually provided on the corresponding columns.
[0029] Furthermore, the lifting cylinder 8 is vertically installed, with its top end being a movable end. The movable end of the lifting cylinder 8 controls the vertical displacement of the vehicle frame 5. The lifting cylinder 8 controls the stable displacement of the hydraulic rod 81 inside the cylinder by transferring hydraulic oil. Because the movement is smooth, the vehicle platform 6 is not easily shaken during displacement. When the lifting cylinder 8 is in the lifting state, the hydraulic rod 81 is in a relatively stable state. Unless the lifting cylinder 8 is controlled to retract the hydraulic rod 81, the lifting cylinder 8 can always maintain the supporting state of the vehicle platform 6, constituting a first layer of protection for the lifting parking equipment in this utility model.
[0030] Furthermore, a support roller 82 is installed on the movable end of the lifting cylinder 8, and a lifting chain 83 is connected to the back side of the vehicle frame 5. The lifting chain 83, the support roller 82, and the lifting cylinder 8 work together to control the vertical displacement of the vehicle frame 5. At least one support roller 82 is installed at the top of the hydraulic rod 81. The support roller 82 can be a toothed wheel structure, and the lifting chain 83 can be replaced with other chain structures depending on the support roller 82 selected. The principle is that the hydraulic rod 81 of the lifting cylinder 8 controls the support roller 82 to move upward, and the support roller 82 drives the lifting chain 83 to pull the vehicle frame 5 to move vertically.
[0031] Furthermore, the laying direction of the protective chain 9 can be adjusted by cooperating with the sprocket 91. That is, the laying direction of the protective chain 9 can be adjusted by wrapping the protective chain 9 around the sprocket 91. Several protective chains can be set inside the column and at the bottom of the vehicle platform 6 as needed, so that at least one chain is laid from the top of the left column 1 downward and extends along the bottom of the vehicle platform 6 to the bottom of the right column 2, and at least one chain is laid from the top of the right column 2 downward and extends along the bottom of the vehicle platform 6 to the bottom of the left column 1.
[0032] Furthermore, the safety anti-fall device 7 includes an anti-fall hook 71, a linkage rod 72, and a micro switch 73. The top of the anti-fall hook 71 is mounted on the vehicle frame 5 via a rotating rod 74. The micro switch 73 controls the anti-fall hook 71 to move out of or retract into the vehicle frame 5 with the rotating rod 74 as the rotation base point via the linkage rod 72. The safety anti-fall device 7 constitutes a first layer of protection for the lifting parking equipment in this utility model.
[0033] Furthermore, the left column 1 and the right column 2 are provided with grooves 21 for connecting and engaging with anti-fall hooks 71.
[0034] Furthermore, brackets 10 are installed on the left column 1 and the right column 2, and control panels are set on the brackets 10.
[0035] Furthermore, the support leg 3 is divided into front support leg 31 and rear support leg 32, which together with the column form a T-shaped structure.
[0036] Furthermore, it also includes a photoelectric sensor, which triggers the micro switch 73 to start.
[0037] When the vehicle platform 6 is adjusted to the bottom of the left column 1 and the right column 2, the top surface of the vehicle platform 6 and the front end of the vehicle platform 6 are on the same plane. According to the original state of the lifting cylinder 8, the matching structure for the vehicle to drive from the equipment into the top of the vehicle platform 6 is reasonably set. For example, when the vehicle platform 6 is adjusted to the lowest end by the lifting cylinder 8, the front end of the vehicle platform 6 is the ground. The lifting parking equipment is installed by opening on the ground.
[0038] The safety anti-fall device 7 can be triggered by a sensor, such as a photoelectric sensor, but not limited to photoelectric sensors, it can also be an infrared sensor, etc.; of course, it can also be triggered by a preset control program to make the vehicle platform 6 move to a predetermined height. The micro switch 73 controls the anti-fall hook 71 to move out of the vehicle frame 5 with the rotating rod as the rotation base point through the linkage rod 72. The anti-fall hook 71 is engaged in the slot 21 to keep the vehicle frame 5 connected to the column and limit the accidental fall of the vehicle frame 5 and the vehicle platform 6 installed on the vehicle frame 5.
[0039] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
