Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stereo garages, and in particular relates to a leveling positioning device for an elevator. Background Art
[0002] During the vehicle storage and retrieval process of the three-dimensional parking equipment, a leveling positioning mechanism is usually set on the elevator, such as Figure 1 As shown, a crank driven by a reduction motor is installed on the lifting frame 1 of the elevator, the crank is hinged to the connecting rod, and the connecting rod is hinged to the pin 2. In order to improve the translation stability of the pin 2, a sleeve 3 compatible with the pin 2 is installed on the elevator. When the elevator reaches the Nth parking rack, the reduction motor drives the pin 2 to extend and insert it into the positioning sleeve 4 on the Nth parking rack to achieve level positioning of the elevator and improve stability during vehicle storage and retrieval.
[0003] However, this leveling positioning mechanism has the following defects: (1) There is sliding friction between the pin shaft 2 and the sleeve 3. After long-term use, the sleeve 3 wears out and the gap between the pin shaft 2 and the sleeve 3 is large, resulting in a large positioning deviation of the pin shaft 2; (2) In order to meet the positioning of the elevator, the pin shaft 2 requires a large shear resistance, so the shaft diameter of the pin shaft 2 is required to be larger. Correspondingly, the volume of the positioning sleeve 4 is large and the weight is heavy. A large number of positioning sleeves 4 are used in the entire three-dimensional parking garage, and a large amount of steel is used, resulting in a large overall weight of the equipment and high production cost.
[0004] Therefore, in the field of stereo garage technology, there is still a need for research and improvement of the elevator leveling positioning device, which is also a research hotspot and focus in the current field of stereo garage technology, and is also the starting point for the completion of the present utility model. Utility Model Content
[0005] Therefore, the technical problem to be solved by the utility model is: to provide a leveling positioning device for an elevator to solve the technical problem that the existing positioning mechanism is large in size, resulting in large overall weight of the equipment and high production cost.
[0006] In order to solve the above technical problems, the technical solution of the utility model is: a lift leveling positioning device, comprising a positioning arm slidably installed on a lift frame, the cross-sectional shape of the positioning arm is a rectangle, a positioning seat is provided on the steel structure frame of the three-dimensional parking garage corresponding to each berth, a positioning shaft is installed on the positioning seat, the free end of the positioning arm is provided with an open groove adapted to the positioning shaft, and the axis of the positioning shaft is perpendicular to the sliding direction of the positioning arm.
[0007] As an improvement, a rotating sleeve is rotatably mounted on the positioning shaft, the rotating sleeve is sleeved on the positioning shaft and is coaxially arranged with the positioning shaft, and the open groove is adapted to a diameter of the rotating sleeve.
[0008] As a further improvement, the open end of the open groove is provided with a guiding slope.
[0009] As another improvement, at least two groups of guide rollers for clamping the positioning arm are installed on the lifting frame, and each group of guide rollers includes an upper roller and a lower roller rotatably installed on the lifting frame, and the gap between the upper roller and the lower roller corresponds to the length of the long side of the rectangular cross-section of the positioning arm.
[0010] As a further improvement, the outer surfaces of the upper roller and the lower roller are provided with positioning grooves, and the width of the positioning grooves corresponds to the length of the short side of the rectangular cross-section of the positioning arm.
[0011] After adopting the above technical solution, the beneficial effects of the utility model are:
[0012] (1) In the embodiment of the utility model, an open groove is provided on the rectangular positioning arm, and a positioning shaft is arranged on the steel structure frame, which not only meets the rigidity and strength requirements of the structure itself, but also reduces the use of steel and reduces the production cost.
[0013] (2) Since a rotating sleeve is rotated on the positioning shaft, the rotating sleeve can rotate, so that the friction between the positioning shaft and the positioning arm changes from sliding friction to rolling friction, thereby reducing the friction between the positioning shaft and the positioning arm and extending the service life of the positioning shaft and the positioning arm.
[0014] (3) Since at least two sets of guide rollers for clamping the positioning arm are installed on the lifting frame, the positioning arm can stably translate between the upper roller and the lower roller, and the sliding friction between the positioning arm and the lifting frame is changed to rolling friction, which further extends the service life of the positioning arm.
[0015] (4) Since the outer surfaces of the upper roller and the lower roller are provided with positioning grooves, the translation direction of the positioning arm is limited, thereby preventing the positioning arm from falling out of the upper roller and the lower roller.

[0022] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments.

[0024] like Figure 2 and Figure 3As shown, the utility model provides a lift leveling positioning device, including a positioning arm 6 slidably mounted on a lift frame 5, the cross-sectional shape of the positioning arm 6 is a rectangle, a positioning seat 8 is provided on the steel structure frame 7 of the stereo garage corresponding to each berth, a positioning shaft 9 is installed on the positioning seat 8, an open groove matched with the positioning shaft 9 is provided at the free end of the positioning arm 6, the open groove is located in the long side direction of the rectangular cross-section of the positioning arm 6, the open groove is open on one side of the positioning shaft 9, and is blocked on the side away from the positioning shaft 9 and has an end face shape of an arc, the axis of the positioning shaft 9 is perpendicular to the sliding direction of the positioning arm 6, this structure has an open groove on the rectangular positioning arm 6, and a positioning shaft 9 is arranged on the steel structure frame 7, which not only meets the rigidity and strength requirements of the structure itself, but also reduces the use of steel and reduces the production cost.
[0025] A rotating sleeve 10 rotates on the positioning shaft 9. The rotating sleeve 10 is sleeved on the positioning shaft 9 and is coaxially arranged with the positioning shaft 9. When the positioning shaft 9 is positioned, the rotating sleeve 10 can rotate, so that the friction between the positioning shaft 9 and the positioning arm 6 changes from sliding friction to rolling friction, thereby reducing the friction between the positioning shaft 9 and the positioning arm 6 and extending the service life of the positioning shaft 9 and the positioning arm 6. The open groove is adapted to the diameter of the rotating sleeve 10, and the open end of the open groove is provided with a guiding inclined surface. When positioning, the positioning shaft 9 can be smoothly introduced into the open groove.
[0026] At least two sets of guide rollers for clamping the positioning arm 6 are installed on the lifting frame 5. Adjacent guide rollers are arranged at intervals in the sliding direction of the positioning arm 6. Each set of guide rollers includes an upper roller 11 and a lower roller 12 rotatably installed on the lifting frame 5. The upper roller 11 and the lower roller 12 are both installed on the lifting frame 5 through bearings. The gap between the upper roller 11 and the lower roller 12 corresponds to the length of the long side of the rectangular cross section of the positioning arm 6, so that the positioning arm 6 can translate stably between the upper roller 11 and the lower roller 12, and the sliding friction between the positioning arm 6 and the lifting frame 5 is changed to rolling friction, which further extends the service life of the positioning arm 6. The outer surfaces of the upper roller 11 and the lower roller 12 are both provided with positioning grooves. The width of the positioning grooves corresponds to the length of the short side of the rectangular cross section of the positioning arm 6, which limits the translation direction of the positioning arm 6 and prevents the positioning arm 6 from slipping out of the upper roller 11 and the lower roller 12.
[0027] During use, when the elevator reaches the Nth parking rack, the reduction motor drives the positioning arm 6 to extend, and the positioning arm 6 translates toward the positioning seat 8 between the upper roller 11 and the lower roller 12. When the positioning shaft 9 is introduced into the open groove, the reduction motor stops to achieve the level positioning of the elevator.
[0028] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
