After the two sides of the car plate 6, the two ends are wound on the first reel 1 and the second reel 1 respectively.

The lifting mechanism of the three-dimensional parking equipment of this embodiment adopts two hoisting ropes instead of four, and the two ends of the hoisting ropes are respectively installed on the reel 1 at the two ends of the drive shaft 2 . Thus, this embodiment can ensure that the vehicle-loading plate 6 is always kept horizontal during the lifting process, and rises or falls steadily; even if the coaxiality of the two reels 1 is not high, or the first lifting rope and the second lifting rope are frequently Special circumstances such as lengthening during use can still ensure the level of the vehicle-carrying plate 6 to prevent the car from falling.

Wherein, "after the first hoisting rope and the second hoisting rope respectively go around the two sides of the vehicle-carrying board 6 along the length direction of the drive shaft 2, the two ends are respectively wound on the first roll drum and the second reel" means: the rope section of the first hoisting rope wound on the vehicle loading plate is parallel to the drive shaft, and the rope section of the second hoisting rope wound on the vehicle loading plate is parallel to the driving shaft ; And, the first hoisting rope and the second hoisting rope hoist the both sides of the loading car plate 6 respectively, if the left side of the first hoisting rope hoisting the loading car plate 6, then the second hoisting rope lifts and lifts the left side of the loading car plate 6 Right.

It should be noted that "the drive shaft is located above the vehicle-carrying plate" means that the height of the drive shaft 2 is above the vehicle-carrying plate, and it is not required that the drive shaft 2 is located directly above the vehicle-carrying plate 6, nor The vertical projection of the drive shaft 2 is required to fall on the vehicle-loading plate 6 .

In Fig. 2, a pulley assembly is arranged on the vehicle-loading board 6, and hoisting ropes (the hoisting ropes all include a first hoisting rope and a second hoisting rope unless otherwise specified) bypass the load-carrying rope through the pulley assembly. Car board 6. In this case, there is rolling friction between the hoisting rope and the vehicle-carrying plate 6, and its frictional force is very small and can be ignored. Tilting, under the gravitational effect of the vehicle-carrying plate 6 (and the vehicle on the vehicle-carrying plate 6), the vehicle-carrying plate 6 can adjust its position by itself, so that the left and right sides of the vehicle-carrying plate 6 remain horizontal.

The pulley assembly of this embodiment, please refer to FIG. 2 further, includes a pulley seat 8 for fixing to the vehicle-carrying board 6 , and a pulley 7 installed on the pulley seat 8 . Wherein, the pulley seat 8 is preferably arranged on the side of the vehicle-carrying plate 6, so as to avoid touching the ground when the pulley seat 8 is arranged on the bottom surface of the vehicle-carrying plate 6, and to avoid setting the pulley seat 8 on the top of the vehicle-carrying plate 6 Affect parking when facing. On this basis, the pulley 7 is installed on the pulley seat 8.

Wherein, preferably but not necessarily, an annular groove is formed in the circumferential direction of the pulley 7, so that the hoisting rope goes around the annular groove of the pulley 7, and then the annular groove can play a role of guiding and limiting the hoisting rope. Of course, in addition to setting an annular groove on the pulley 7 to guide and limit the hoisting rope, other methods can also be used to limit the hoisting rope.

Please refer to FIGS. 3-5 , the pulley seat 8 of this embodiment includes a backing plate 13 , ribs and lifting lugs 11 .

Wherein, the backing plate 13 is used to fix the side of the vehicle-carrying plate 6, and it can be seen from the accompanying drawing 4 that the backing plate 13 is in a right-angle structure as a whole, including a first backing plate and a second backing plate connected to each other, And threaded holes are provided on the first backing plate and the second backing plate, so that bolts or screws are passed through the threaded holes to install the backing plate 13 on the vehicle-carrying plate 6 .

In addition, the ribs and the backing plate 13 are fixed. Also, the ribs can be divided into the installation ribs 14 and the reinforcement ribs 12 and 15 . The ribs 14 are installed in two pieces and are parallel to each other. A pair of mounting holes for the pulley shaft 10 are provided on the mounting rib 14. After the pulley 7 is installed on the pulley shaft 10 through the bearing 16, the two ends of the pulley shaft 10 pass through the mounting holes and pass through the spring washer 17. It is fixed with the installation rib 14. The effect of stiffener plate 12,15 is mainly to guarantee the structural strength of pulley seat 8.

The lifting lug 11 is fixed on the backing plate 13 . After the vehicle-loading plate 6 is hoisted to the set height, the current position of the vehicle-loading plate 6 cannot always be maintained by the hoisting rope, so the lifting lug 11 is designed in this embodiment. The lifting lug 11 is used to connect with the anti-drop hook, and is used to hoist and fix the vehicle-carrying board 6 after the car-carrying board 6 is raised to a set position.

The pulley seat 8 in this embodiment further includes a connecting plate 9 , and the pulley seat 8 is connected to the installation guide rail 19 through the connecting plate 9 . Wherein, the connecting plate 9 can be welded with the installation guide rail 19 and connected with the vehicle-carrying plate 6 through high-strength bolts.

Of course, the specific structure of the pulley seat 8 in this embodiment is not limited by the drawings, as long as the pulley 7 can be installed on the vehicle-carrying board 6 . Moreover, the installation position of the pulley seat 8 is not limited, as long as it guarantees that the hoisting rope bypasses the pulley 7 on the pulley seat 8, the hoisting requirements of the hoisting rope to the vehicle-carrying plate 6 can be satisfied.

Further, the pulley seat 8 is also provided with a limit pin 18 parallel to the pulley shaft 10, and the limit pin 18 is installed under the pulley shaft 10 for supporting the See Figure 6 for the lifting rope. Therefore, when the hoisting rope is not stressed, the limit pin shaft 18 can play the role of lead protection for the hoisting rope, thereby ensuring that when the hoisting rope changes from a loose state to a tensioned state, the hoisting rope can be well positioned. in the ring groove of the pulley.

In the present embodiment, when the vehicle-loading plate 6 is rectangular, and the drive shaft 2 is along the width direction of the vehicle-loading plate 6 (wherein the width direction is also the left and right direction of the vehicle-loading plate 6, the left and right here are Judging based on the orientation of the vehicle when the vehicle is parked on the vehicle-carrying plate 6, and also when the left and right orientations of accompanying drawing 2) are distributed, in order to ensure the smooth lifting of the vehicle-loading plate 6, as long as the first hoisting rope is hoisted The front side of the vehicle-carrying plate 6, the rear side of the second hoisting rope lifting the car-carrying plate 6 (the front side and the rear side here are judged based on the orientation of the vehicle when the vehicle is parked on the vehicle-carrying plate 6 equally) get).

Therefore, in this embodiment, preferably but not necessarily, the number of pulleys 7 is four, and the pulley seats 8 are respectively arranged near the four corners of the vehicle-carrying board 6 . Wherein, the first hoisting rope goes around the two pulleys 7 on the front side of the vehicle-loading plate 6 , and the second hoisting rope goes around the two pulleys 7 on the rear side of the vehicle-loading plate 6 .

Of course, in order to better meet the installation requirements between the hoisting rope and the drive shaft 2 after the hoisting rope bypasses the vehicle-carrying plate 6, a corresponding guide structure can be set on the car-loading plate 6 or other positions, so that the hoisting rope passes through the guiding structure. It can be smoothly wound onto the reel 1.

It should be noted that, when the vehicle-loading plate 6 is rectangular, the drive shaft 2 can be distributed not only along the width direction of the vehicle-loading plate 6, but also along the length direction of the vehicle-loading plate 6, or even along any direction. distributed.

When the drive shaft 2 is distributed along the lengthwise direction of the vehicle-carrying plate 6, the first reel 1 is installed on the first end of the drive shaft 2 at this moment, and is positioned at the front side of the vehicle-carrying plate 6 (here The front side is judged based on the orientation of the vehicle when the vehicle is parked on the vehicle-carrying plate 6); The rear side is determined based on the orientation of the vehicle when the vehicle is parked on the vehicle-loading plate 6). Thus, the left side of the first hoisting rope lifts the car-loading plate 6, and the second hoisting rope lifts the right side of the car-loading plate 6 (the front side and the rear side here are also when a vehicle is parked on the car-loading plate 6 The orientation of the vehicle is determined based on the reference).

In addition, the structure of the vehicle-loading board 6 is not limited by examples, for example, the vehicle-loading board 6 may also be circular, elliptical, polygonal or even shaped. And, no matter what shape the vehicle-loading plate 6 is, the positional relationship between the two hoisting ropes and the vehicle-loading plate 6 is based on the fact that the lifting ropes can reliably lift the vehicle-loading plate 6 . Therefore, the installation position of the drive shaft 2, the installation position of the reel 1 on the drive shaft 2, and the installation position of the hoisting rope also change with the structure of the vehicle-loading plate 6.

It is worth mentioning that the hoisting rope can be connected with the vehicle-carrying plate 6 in other ways besides using a pulley assembly to connect with the vehicle-carrying plate 6. As long as it is ensured that the vehicle-carrying plate 6 has a tendency to incline, the vehicle-carrying plate 6 will It can slide relative to the hoisting rope to automatically adjust the balance of the vehicle-loading plate 6 to get final product.

For example, in this embodiment, a plurality of piercing rings may also be provided on the vehicle-carrying plate 6 . On this basis, the lifting rope is passed through the wearing ring, and the balance of the vehicle-loading plate 6 can also be adjusted.

For another example, it can be found from FIG. 6 that an installation guide rail 19 is provided at the bottom of the vehicle loading plate 6 , and the hoisting rope is passed through the installation guide rail 19 . Once the vehicle loading plate 6 tends to tilt, the hoisting rope will slide along the installation guide rail 19 to adjust the balance of the vehicle loading plate 6 .

And it should be noted that the installation guide rail 19 is arranged at the bottom end of the vehicle loading plate 6 , which can not only limit and guide the hoisting rope, but also strengthen the structural strength of the vehicle loading plate 6 . Of course, the installation guide rail 19 can also be arranged at any other suitable position, as long as it can guarantee the guide limit to the hoisting rope.

This embodiment selects the best solution, please refer to Fig. 6, on the basis of being provided with the installation guide rail 19, pulleys 7 are arranged at both ends of the installation guide rail 19, thereby not only ensuring the friction force between the vehicle-carrying plate 6 and the hoisting rope It is very small to improve the self-balancing adjustment capability of the vehicle-carrying board 6;

On the basis that the installation guide rail 19 is provided, it is preferable that a plurality of guide plates with guide holes are distributed in the installation guide rail 19 along its length direction. The guide hole on the guide plate further ensures that the hoisting rope moves in a specific direction.

Wherein, the installation guide rail 19 is preferably but not necessarily in the form of channel steel. For example, the installation guide rail 19 in the accompanying drawing 6 is in the form of U-shaped steel, so as to ensure that the hoisting rope runs in the inner space of the U-shaped steel.

Based on the above, the present embodiment is provided with a front bumper plate and a rear bumper plate for limiting the running of the car on the vehicle-loading plate 6 . Thereby, when the vehicle travels on the vehicle-carrying board 6 , the front bumper can prevent the vehicle from leaving the vehicle-carrying board 6 . And the tailgate can prevent the vehicle from going backwards on the vehicle-carrying plate 6 .

In this embodiment, the hoisting rope is preferably but not necessarily a steel wire rope 3 .

The above embodiments are only used to illustrate the present invention, but not to limit the present invention.
