Detailed Description
The utility model is further illustrated by the following examples, which are intended to be illustrative only and not limiting in any way.
The utility model relates to a self-adjusting telescopic audience mobile seat, which comprises a mobile stand 6 and a transverse tunnel 4, wherein two sides of an innermost frame of the mobile stand are respectively provided with a driving motor unit (not shown in the figure), and lifting units are arranged in the transverse tunnel, and the innovation of the utility model is that: two sides of the rear end face of the movable stand are respectively provided with a laser transmitting and receiving unit 10, and two laser reflecting plates 7 are arranged on the rear ground, the building or the support of the movable stand which is aligned with the two laser transmitting and receiving units.
The laser emitted by the emitting module of the laser emitting and receiving unit is reflected by the laser reflecting plate and then received by the receiving module of the laser emitting and receiving unit; the output ends of the two receiving modules are connected with a control unit, and the control unit can automatically control the rotating speed of the driving motor unit according to the data measured by the two laser transmitting and receiving units.
As shown in fig. 1 and 2, a laser emitting plate 7 is respectively disposed on both sides of the front surface of the middle palace 2, and a laser emitting and receiving unit 10 is respectively disposed on both sides of a frame (the last frame from the rear side to the front in the drawing, or the last frame).
Two sides of the rear end of the top plate 9 at the upper end of the lifting unit are respectively provided with a laser reflecting plate 7. The two laser reflecting plates are used for being matched with the two laser transmitting and receiving units at the rear end of the movable stand when the movable stand leaves the top plate. The two laser reflecting plates of the top plate are used for measuring the distance between two sides of the movable stand when the movable stand moves away from the top plate, and the two laser reflecting plates at the rear side of the transverse tunnel are used for measuring the distance between two sides of the movable stand after the turning plate is buckled when the movable stand moves, so that whether the whole movable stand is inclined or not can be judged through the distance measurement between the two sides in the whole moving process of the movable stand. When skew occurs, the control unit can control the rotational speeds of the driving motor units at both sides of the innermost frame, thereby adjusting the skew state.
Both sides of the innermost frame and both sides of the frame at the rear side of the movable stand are respectively provided with a stay wire encoder; the output ends of the two stay wire encoders are connected with the control unit. The two stay wire encoders are used for detecting the moving distance of two sides of the innermost frame when the movable stand is unfolded integrally. The wire ends of the wire-drawing type encoders can be fixed on the side surfaces of the first frame and the second frame which are counted forward from the rear side of the movable stand, the encoders of the wire-drawing type encoders are fixed on the side surfaces of the innermost frame of the movable stand, when the movable stand is integrally unfolded, the innermost frame moves and gradually pulls out all the frames, and the two wire-drawing type encoders can detect whether the movement of the innermost frame is askew or not.
The application process of the utility model is as follows:
Initial state: the empty places among the three palace can be used for activities such as passing, performing and the like.
At this time, the movable stand is entirely located on the top plate 9 of the lifting unit, and the movement end of the swing driving cylinder 8 is in a retracted state, so that the turning plate 5 is buckled at the opening of the upper end of the transverse tunnel 4.
When the device is ready to be used:
The movement end of the swing driving cylinder extends out to swing and open the flap along the flap hinge support 12.
The moving end of the lifting cylinder 11 pushes the top plate, the movable stand is lifted upwards, after the top plate is lifted in place, the movable stand moves to the ground at the front side of the transverse tunnel (all frames are fixed together by binding belts, chains and the like), and when moving, laser emitted by the laser emitting and receiving unit is emitted back by the laser reflecting plate on the top plate, and the control unit judges whether the two sides of the movable stand are askew or not after receiving the laser. When there is no skew, the control unit controls the rotation speed of the motor in the driving motor units at both sides of the innermost frame to return the frame to a substantially lateral state when moving.
When the movable stand leaves the top bar as shown in fig. 2, the moving end of the lifting cylinder is retracted and the top plate is lowered, and then the turning plate is buckled slowly.
At this time, the movable stand moves in the direction of the palace 2 (the rear direction, the direction between palace 1 and palace 2) of fig. 1, and at this time, the laser transmitting/receiving unit cooperates with the laser transmitting board on the wall surface of the palace as shown in fig. 3, that is, when the movable stand moves, the skew state of both sides of the movable stand is detected, and the control unit adjusts the movable stand to recover the substantially transverse state. The laser transmitting plate on the top plate and the laser transmitting and receiving unit of the movable stand can also realize the positioning and adjustment of the movable position of the movable stand after moving to the top plate.
When the movable stand moves to the palace 2, a last frame or a frame with the reciprocal is fixed, the structures such as a binding belt or a chain for fixing all frames are loosened, the innermost frame moves to a direction far away from the palace 2, all frames are gradually pulled out and finally form a ladder-like shape, and in the moving process, the laser emitting and receiving unit and the laser emitting plate still cooperate with each other to work, so that the skew condition of the innermost frame during moving is reduced.
The lifting manner driven by the lifting cylinder can use a common lifting structure such as a scissor-fork type lifter structure, and the like, and the lifting structure is fixed on the base 13 of the transverse tunnel. The lifting cylinder can be a hydraulic cylinder capable of lifting a large load, and the swing driving cylinder can also be a hydraulic cylinder.
Through the cooperation of above-mentioned structure, whether portable stand self moves and when expanding or shrink can both carry out crooked detection and correction, guaranteed the accuracy that portable stand moved in narrow and small space position, be favorable to overall arrangement and use.
