It is composed of a metal structure frame, a carrier, a drive system, a control system, and a safety and detection system. Vertical circulation parking equipment has the advantages of saving space, small footprint, and easy operation, and has great application prospects. In recent years, the development of vertical circulation parking equipment has attracted more and more attention.

[0003] Chinese patent CN113605756A discloses a vertical circulation stereoscopic parking garage with positive entry and exit, comprising a main frame, guide rails, a transmission system, a lifting chain, a hanging basket, and an auxiliary guide rail. The guide rails, the transmission system, the lifting chain, and the auxiliary guide rails are all installed on the main frame, a parking area is formed in the main frame, a hanging basket is installed on the lifting chain, a chain roller is arranged on the lifting chain, a guide wheel is installed on the hanging basket, and the guide wheel is arranged in the guide rail; the transmission system comprises a motor, a transmission chain, a sprocket, a shift fork, and a transmission shaft, the motor shaft of the motor is connected to the transmission chain, the rotation of the motor shaft drives the transmission chain to move, the movement of the transmission chain drives the sprocket to rotate, the shift fork follows the sprocket movement, the movement of the shift fork drives the chain roller of the lifting chain to move, thereby driving the hanging basket to perform cyclic repeated movements.

[0004] Chinese patent CN113653381A discloses a transmission device for a vertical circulation stereo garage, comprising a reduction motor, a pinion, a gear, a sprocket, a lifting chain, an upper transmission horizontal shaft, a lower transmission horizontal shaft and a constraint track; the reduction motor is fixed on the garage frame beam; the pinion is fixed to the end of the reduction motor output shaft and meshes with the gear; the upper transmission horizontal shaft and the lower transmission horizontal shaft are fixedly connected to the garage frame through two bearing seats located on the garage horizontal frame; the gear is fixed on one end of the lower transmission horizontal shaft close to the reduction motor; the sprocket and the lifting chain are each divided into two groups, which are respectively fixed at the two ends of the upper transmission horizontal shaft and the lower transmission horizontal shaft; the lifting chain is composed of a lifting fork chain plate, a fork chain plate, a common chain plate, a pin shaft, a sleeve and a constraint roller; the constraint track is arranged on both sides of the lifting chain.

[0005] Chinese patent CN111395834A discloses a double-chain double-axis gear bearing transmission structure of a derailleur plate of a stereo garage, which includes a front frame, a rear frame, a derailleur plate, and a transmission shaft, wherein the output shaft of the driving device is provided with a first sprocket, the output shaft is connected to one end of the driving shaft through a first coupling, the other end of the driving shaft is equipped with a second sprocket, the driving shaft is connected to the rear frame through a first bearing seat, and the driving shaft is parallel to the transmission shaft; the third and fourth sprockets installed on the transmission shaft are respectively driven by the first and second sprockets through a transmission chain, and gears are respectively installed at both ends of the transmission shaft, the gears are meshed with the inner gear ring of the internal gear type slewing bearing, the inner end surface of the inner gear ring is equipped with a derailleur plate, and the outer ring of the internal gear type slewing bearing is respectively fixed to the front frame and the rear frame.

[0006] The operation of vertical circulation mechanical parking equipment mainly relies on a main drive shaft to drive the chain fork to rotate, and the fork drives the chain to run along the circular track, thereby completing the up and down circulation of the parking space. The two ends of the main drive shaft are fixed to the mounting plate on the equipment frame with vertical seat bearings. The current bearing seat mounting holes are oblong holes, which are connected to the bearing seat mounting plate by bolts and nuts. However, the studs of the bolts are usually cylindrical, which causes the bearing seat to deviate when the force is greater than the friction formed by the locking of the bolt assembly. During the operation of the vertical circulation mechanical parking equipment, the bearing seat will generate a force to move horizontally due to the reaction force generated when the fork drives the chain. The friction between the bearing seat and the mounting plate is not enough to offset this horizontal force, causing the drive shaft to deviate from the center, thereby causing equipment failure, and more seriously, damage to equipment parts.

[0007] In addition, the main positioning methods of multi-story parking garages generally include touch-type electrical limit switch positioning, proximity switch positioning, encoder positioning and other methods. Among them, the method of using encoder positioning is particularly widely used. The traditional encoder fixing method is rigid fixation, that is, the encoder and the drive shaft are connected with a concentric connecting shaft, and the encoder bracket is directly fixed to the equipment frame with bolts.

[0008] However, since the drive shaft is a moving part, there will be slight vibrations when the equipment is running. In addition, after the equipment has been running for a long time, the drive shaft may even be slightly deformed, and the straightness of the drive shaft cannot be guaranteed. The vibration generated when the equipment is running and the slight deformation of the drive shaft will cause the encoder and the drive shaft to be non-concentric. Since the encoder and the equipment are rigidly connected, the deflection force generated by the concentric connecting shaft can easily cause damage to the encoder, causing the equipment to lose its positioning function and the entire equipment to be unusable.

[0009] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0010] The purpose of the present invention is to provide a concentric axis positioning speed measuring device for a vertical circulation garage in view of the deficiencies in the prior art.

[0011] In order to achieve the above object, the technical solution adopted by the present invention is:

[0012] The transmission gear of the present invention is a gear shifting device, and the gear shifting device is a gear shifting device, and the gear shifting device is a gear shifting device. The gear shifting device is a gear shifting device, and the gear shifting device is a gear shifting device. The gear shifting device is a gear shifting device, and the gear shifting device is a gear shifting device.

[0013] The main transmission shaft is connected with a coaxial connecting shaft, and an encoder mounting plate is connected between the two vertical connecting columns. The encoder mounting plate is provided with a connecting through hole, and the coaxial connecting shaft passes through the connecting through hole to connect the encoder. The encoder is installed on an encoder mounting frame, and the encoder mounting frame and the encoder mounting plate are connected by a flexible connecting piece.

[0014] The inclined surface of the fixed wedge block is provided with an inclined slot, the inclined slot is parallel to the inclined direction of the inclined surface of the fixed wedge block, and one side surface of the movable wedge block is inserted into the inclined slot.

[0015] In the initial installation state, the base of the bearing seat abuts against the movable wedge block at a height of (1 / 4-3 / 4) h1, wherein h1 is the total vertical height of the movable wedge block; the upper and lower ends of the inclined surface of the movable wedge block are both located in the inclined slide groove.

[0016] The height h2 of the fixed wedge block is greater than 1.7 times h1.

[0017] The encoder mounting plate is an "X"-shaped structure, and its two legs are connected to two vertical connecting columns through a bolt assembly.

[0018] A group of adjustment holes are respectively arranged on both sides above the connecting through hole, and mounting holes are respectively arranged on both sides of the encoder mounting frame, and the mounting holes are connected to the adjustment holes through tension springs.

Specifically, the present invention provides a concentric axis positioning and speed measuring device for a vertical circulation garage, wherein a fixed wedge block and a movable wedge block are respectively arranged on both sides of a bearing seat. The force generated when the inclined surface of the movable wedge block faces the bearing seat is an inclined downward force, which can be decomposed into a horizontal thrust toward the middle and a vertical downward pressure, thereby ensuring the stability of the bearing seat in both the vertical and horizontal directions, thereby playing a clamping and positioning role, and preventing the bearing seat from being affected by the reaction force generated when the shift fork shifts the chain and moving in the horizontal direction.

[0022] In addition, the mounting holes on both sides of the encoder bracket and the center of the concentric connecting shaft form a stable connecting surface. Moreover, since the mounting holes and the adjustment holes of the encoder mounting plate are connected by flexible connectors, even if the spindle vibrates when the equipment is running, the connecting surface always remains perpendicular to the connecting shaft, which can eliminate the deflection force caused by the eccentricity, avoid the damage to the encoder caused by the deflection force caused by the eccentricity, extend the service life of the encoder, ensure the performance of the equipment and reduce the failure points of the equipment.

[0033] Since a fixed wedge block and a movable wedge block are respectively arranged on both sides of the bearing seat, the force generated when the inclined surface of the movable wedge block faces the bearing seat is an inclined downward force, which can be decomposed into a horizontal thrust toward the middle and a vertical downward pressure, thereby ensuring the stability of the bearing seat in both vertical and horizontal directions, thereby playing a clamping and positioning role, and preventing the bearing seat from being affected by the reaction force generated when the shift fork shifts the chain and moving in the horizontal direction.

[0034] The main transmission shaft 1 is connected with a concentric connecting shaft 11, and an encoder mounting plate 9 is connected between the two vertical connecting columns 3.
