DETAILED DESCRIPTION

[0020] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0021] Please refer to Figures 1-10 The present application provides a technical solution: a furniture plate roadway stacking device, comprising a single column roadway machine, which comprises a lower track 4, a lifting track 2, a power box 1 and an object carrying unit 3. The power box 1 comprises a support frame 11, and the support frame 11 is provided with a cover frame 12 on both sides. The lifting track 2 is fixed on the upper track 41 through a roller on the top. The power box 1 is provided with a capstan frame 13, which is rotatably connected with a first rotating shaft 211 through a bearing. A wire capstan 21 is connected with the first rotating shaft 211 through a key and rotates together with the first rotating shaft 211. The power box 1 is provided with a motor for driving the first rotating shaft 211 to rotate. The bottom of the power box 1 is rotatably connected with a second rotating shaft through a bearing. A drive wheel 62 is fixedly connected with the second rotating shaft through a key. The drive wheel 62 is made of elastic rubber and is attached to the top of the lower track 4. The second rotating shaft is also driven by a motor to rotate the drive wheel 62. The buffer mechanism 5 comprises a damping shaft 52 rotatably connected with the power box 1 through a bearing. The damping shaft 52 can slide axially along the bearing. The first rotating shaft 211 is fixedly connected with a first tension wheel 51 through a key. The first tension wheel 51 deforms with the rotation of the wire capstan 21, so that the diameter of the first tension wheel 51 increases. When the diameter increases, the first tension wheel 51 couples with the damping shaft 52. At this time, the resistance of the first rotating shaft 211 is increased by means of the damping shaft 52. When the load is empty, the rotation speed of the first rotating shaft 211 increases. When the speed reaches a certain degree, the centrifugal force makes the diameter of the first tension wheel 51 increase, so as to reduce the speed of the wire capstan 21 intermittently, thereby reducing the shaking of the object carrying unit 3 when the load is empty and prolonging the service life.

[0022] In another embodiment of the present application, a telescopic cylinder 54 for driving the damping shaft 52 to move axially is fixedly arranged on the power box 1 through a screw. The telescopic cylinder 54 can be a gas cylinder or a hydraulic cylinder, which is connected with the damping shaft 52 through a connecting rod 72. The connecting rod 72 is rotatably connected with the damping shaft 52 through a bearing. The connecting rod 72 is provided with a pushing inclined surface 721 and a pulling plate 73. The pushing inclined surface 721 is arranged on the side of the connecting rod 72 close to the damping shaft 52, and the pulling plate 73 is arranged on the side of the connecting rod 72 away from the damping shaft 52. The telescopic cylinder 54 can drive the damping shaft 52 to move axially through the connecting rod 72, so as to adjust the tension of the wire capstan 21. Figure 3For reference, a spring 531 and a friction disc 53 are sequentially provided at the other end of the damping shaft 52. The friction disc 53 adheres to the inner wall of the power box 1. When the damping force needs to be changed, the damping shaft 52 is pushed by the telescopic cylinder 54 to slide along the axis, thereby compressing the spring 531 and changing the damping force to change according to the running speed or the weight of the load.

[0023] In another embodiment provided by the present invention, the first tension wheel 51 includes a fixed ring 511 coaxially arranged with the wire winch 21, the fixed ring 511 is fixedly connected to the first rotating shaft 211 by a key, the fixed ring 511 is elastically connected to a circular arc bar 510, the circular arc bar 510 is provided with a slide groove 5101, a limiting bar 514 is provided between the two circular arc bars 510, the limiting bar 514 is provided with a slide column 5141, the slide column 5141 is slidably connected to the slide groove 5101, and the elastic connection method is as follows: The elastic bending strip 512 is bent, and a friction strip 5102 is provided on the arc strip 510 for friction transmission with the damping shaft 52. When the rotation speed of the first rotating shaft 211 increases, the elastic bending strip 512 stretches. At this time, the limiting strip 514 limits the arc strips 510 that move away from each other to form a more regular circle. The circle surrounded by the arc strip 510 and the limiting strip 514 continues to increase with the increase of centrifugal force. The friction transmission is achieved by coupling the damping shaft 52 with the friction strip 5102 on the arc strip 510.

[0024] In another embodiment provided by the present invention, an elastic bending strip 512 is provided between the fixed ring 511 and the arc strip 510, and a narrowing portion 513 is provided on the end of the elastic bending strip 512 on the first tension wheel 51 that is close to the fixed ring 511. The diameter of the narrowing portion 513 is smaller and it is easier to deform under the action of centrifugal force. When the arc strip 510 contacts the damping shaft 52 for friction transmission, the rotation speed of the first rotating shaft 211 decreases, and the deceleration degree of the first tension wheel 51 with inertia is greater, so that the position of the arc strip 510 and the fixed ring 511 is offset and misaligned, so as to buffer the damping force of the contact damping shaft 52, so that the deceleration effect on the first rotating shaft 211 is changed from direct deceleration of a force to buffered deceleration, thereby further reducing shaking.

[0025] In another embodiment of the present invention, a cone wheel 521 is provided on the damping shaft 52. When the telescopic cylinder 54 drives the first rotating shaft 211 to move along the axial direction, the cone wheel 521 moves axially with the damping shaft 52 and couples or decouples with the first tension wheel 51. Figure 3 As shown, when the telescopic cylinder 54 is extended, the large end of the cone wheel 521 is pushed away from the first tension wheel 51. At this time, the cone wheel 521 and the damping shaft 52 are decoupled, and the damping force of the large damping shaft 52 is increased. When the telescopic cylinder 54 is retracted, the spring 531 is stretched and the large end of the cone wheel 521 is coupled to the first tension wheel 51.

[0026] Preferably, a counterweight device, such as a flywheel, can be provided on the damping shaft 52, so as to maintain the rotation of the flywheel during the operation and movement of the power box 1. The damping shaft 52 and the flywheel are unidirectionally coupled, so that when the speed of the damping shaft 52 gradually decreases due to the damping force, the rotation speed of the flywheel decreases slower than that of the damping shaft 52.

[0027] In another embodiment provided by the present invention, a fixed frame 71 carrying one of the auxiliary clamping wheels 60 is provided on the inner wall of the power box 1, and a connecting rod 72 carrying the other auxiliary clamping wheel 60 is slidably connected to the fixed frame 71. A pulling plate 73 is fixedly connected to the connecting rod 72 through an elastic member (the elastic member is a tension spring). The pulling plate 73 is fixedly connected to the inner wall of the fixed frame 71, and the tension spring pulls the connecting rod 72 to slide, so that the other auxiliary clamping wheel 60 slides with the connecting rod 72 to increase the clamping force.

[0028] Preferably, a pushing inclined surface 721 is provided on the connecting rod 72, and a second tension wheel 61 is coaxially provided on the driving wheel 62. The structure of the second tension wheel 61 is the same as that of the first tension wheel 51, that is, the second tension wheel 61 includes a fixed ring 511 and an arc bar 510 arranged in a circumferential array along the fixed ring 511, and the arc bar 510 is slidably connected with a limiting bar 514 for limiting. However, the difference is that the elastic bending bar 512 on the second tension wheel 61 does not have a narrowing portion 513, and the arc bar 510 is not provided with a friction bar 5102, but a smooth layer is provided. Similarly, when the second rotating shaft rotates too fast, the elastic bending bar 512 is stretched by the centrifugal force. At this time, the diameter of the arc bar 510 increases and pushes against the pushing inclined surface 721, causing the connecting rod 72 to slide, thereby increasing the pushing force of the auxiliary clamping wheel 60 on the connecting rod 72, so as to further reduce the shaking by increasing the clamping force of the auxiliary clamping wheel 60 when the speed is too fast.

[0029] When the object-holding unit 3 moves along the lifting track 2 at a high speed in the empty state, the telescopic cylinder 54 is driven to extend, compressing the spring 531 and increasing the damping force of the damping shaft 52. The first rotating shaft 211 is driven to rotate by the motor, so as to drive the steel wire winch 21 to rotate and lift or lower the object-holding unit 3. When the rotating speed of the steel wire winch 21 increases, the elastic bending strip 512 is stretched due to the centrifugal force. At this time, the limiting strip 514 limits the mutual separation of the circular-arc strips 510 to form a relatively regular circle. The circle surrounded by the circular-arc strips 510 and the limiting strip 514 is continuously increased in diameter, and the coupling damping shaft 52 increases the diameter of the tension pulley 51, so as to decelerate the steel wire winch 21. When the coupling occurs, the narrowing part 513 is increased in bending degree, so that the deceleration effect on the first rotating shaft 211 is changed from direct deceleration of a force to buffer deceleration. The deceleration of the object-holding unit 3 is completed, and the shaking caused by inertia is reduced. When the object-holding unit 3 carries the goods and moves downward along the lifting track 2, the goods are not easy to shake due to the gravity of the goods. At this time, the telescopic cylinder 54 is driven to retract, stretching the spring 531 and reducing the damping force of the damping shaft 52. At the same time, the bevel gear 521 is always coupled with the first tension pulley 51, limiting the diameter of the first tension pulley 51 to be constant, so as to reduce the resistance when the object-holding unit 3 carries the goods and moves downward at a high speed.

[0030] When the power box 1 is driven to move along the lower track 4, the second rotating shaft is driven to rotate by the motor, so that the driving wheel 62 moves along the lower track 4. When the moving speed of the power box 1 increases, the rotating speed of the second rotating shaft increases. At this time, the second tension pulley 61 is increased in diameter due to the centrifugal force, and is pushed to the inclined surface 721 by the circular-arc strips 510, so as to increase the clamping force of the auxiliary clamping wheel 60 and stabilize the fixation of the power box 1 and the lower track 4.

[0031] The above describes certain exemplary embodiments of the present application by way of illustration only, and it is obvious to those skilled in the art that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature, and should not be construed as limiting the scope of the claims of the present application.
