Background

The elevator in the intelligent warehouse system generally refers to an elevator mechanism arranged beside the three-dimensional warehouse, and has the function of carrying out elevator layer change on goods and/or a shuttle. In addition, the elevator car of the elevator, its function is similar to the car of elevator, is used for temporarily placing goods and shuttle to connect the chain, guarantee the power of lifting action can be effectively input.

On the other hand, when the shuttle car is driven into the car together with the heavier cargo, the car is allowed to largely settle, and the chain is greatly worn. Therefore, the function of the hovering mechanism is to make the car have a rigid supporting effect after the car reaches the floor changing height and before the shuttle is driven in together with the cargoes. Thus, the nature of the hover mechanism is to share the forces on the chain. Of course, when the car is lifted normally, the supporting function of the suspending mechanism needs to be closed, and the suspending mechanism cannot be clamped on the lifting path of the car.

The general method of use of the hover mechanism in this patent is as follows: when the lift car normally goes up and down, the suspension motor is controlled to retract the suspension plate, the suspension plate and the suspension frame cannot be touched, after the lift car properly upwards passes through the suspension plate, the suspension plate is supported by the suspension motor, the lift car descends a small margin at the moment, the suspension frame can be erected on the suspension plate, and the rigid suspension effect is effective at the moment.

However, the hovering mechanism has at least the following 2 defects in the actual use process, and is also the technical problem to be solved by the utility model, namely:

firstly, the acting direction of the hovering motor is the force application direction of the hovering mechanism, so that the motor is frequently pressed for a long time and is easy to fail;

secondly, for the lift car, the action positions of the suspension mechanisms are all on the side edges and are in 4 point-shaped independent distribution, so that the rigid supporting sites born by the lift car are too concentrated and close to the side edges, and the lift car is not stable enough when suspended.

Therefore, in view of the foregoing, there is an urgent need for a novel hover mechanism with greater rigid support strength and better support stability for use in a hoist of a stereoscopic garage.

Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1 to 7, a suspending mechanism for a hoist car comprises a suspending plate unit 1 arranged on a hoist column a, a vertical shaft unit 2 arranged on the lower surface of a car bottom plate b, and 2 rotating plate units 3 which are sleeved on the vertical shaft unit 2 and are used for supporting on the suspending plate unit 1 in a transverse rotating manner.

In this embodiment, the car achieves the purpose of floor changing and lifting of cargoes and/or shuttles through the existing chain and the matched control mechanism.

Wherein, this mechanism of hovering's effect is: when the car stops at the corresponding three-dimensional garage, a rigid supporting effect is provided for the car, otherwise, the car can be greatly settled when goods and/or a shuttle enter the car, and the chain of the elevator can be seriously damaged. Correspondingly, for the hovering mechanism, the most basic requirement is to ensure that the rigid supporting function is controllable to open and close, and the normal lifting use of the lift car cannot be influenced.

In addition, 2 rotor plate units 3 form scissors formula structure, and the hover effect can be closed when guaranteeing to draw close each other, and the hover effect can be opened when rotatory opening, moreover rotor plate unit 3's bulge is not in three-dimensional storehouse track c department, also is not in stand crossbeam d department, consequently can not interfere the lift action of car.

Finally, the four hovering plate units 1 are in a group, each three-dimensional garage layer to be hovered corresponds to one group of hovering plate units 1, and when a lift car hovers, the lift car track is ensured to be opposite to the three-dimensional garage track.

The swivel plate unit 3 includes a plate body 301 having both ends exposed to the outside of the car floor b, and a mounting hole 302 provided on the plate body 301 for inserting the vertical shaft unit 2.

In the present embodiment, the scissor type hover structure includes 4 protruding ends, i.e., corresponding to 4 of the hover plate units 1. In other words, the length of the plate 301 is greater than the long side dimension of the car floor b.

The rotating plate unit 3 further includes a slot 303 provided on the plate 301 and provided with the mounting hole 302 for engaging with another plate 301.

In this embodiment, the vertical slot depth of the slot 303 is half the thickness of the plate 301, and after 2 plate 301 are vertically staggered at the slot 303, the car bottom plate b can be supported at the same time, so that the supporting effect of the hovering mechanism is not "punctiform", but the supporting area is at least the sum of the upper surface areas of 2 plate 301, and the "planar" supporting manner is more comprehensive and stable.

The rotating plate unit 3 further includes an end surface engagement groove 304 provided on the plate body 301 and used for inserting the hovering plate unit 1.

In this embodiment, if the end surface engagement groove 304 is not provided, the plate body 301 may be only installed on the upper surface of the hovering plate unit 1, and the hovering fixing direction is only fixed downward at this time, and when the shuttle leaves the car, the car may rise upward, although to a small extent, but still needs to be avoided.

At this time, the end surface clamping groove 304 is clamped on the hovering plate unit 1, so that the upward and downward immobility of the lift car is ensured when the lift car hovers, and a more comprehensive hovering and fixing effect can be realized.

Of course, even if the end surface engagement groove 304 is provided, the original suspended state of the plate 301 can be used.

The vertical shaft unit 2 comprises a fixed shaft 201 which is arranged on the lower surface of the car bottom plate b and is inserted into the two mounting holes 302, and a limiting block 202 which is arranged on the lower end surface of the fixed shaft 201.

In this embodiment, the limiting block 202 is configured to vertically fix 2 boards 301 on the car bottom board b, so as to ensure that the boards 301 can only rotate laterally and cannot drop down.

The rotating plate unit 3 further includes 2 protruding plates 305 provided on the lower surface of the car bottom plate b for receiving the jacking forces of the two plate bodies 301; the vertical shaft unit 2 further includes a spacer 203 disposed on the fixed shaft 201 and above the two plate bodies 301.

In the prior art, various other structures or various electrified components may need to be installed on the lower surface of the car floor b, and thus the car floor b may not provide a sufficiently large rotation plane for the plate body 301.

In this embodiment, the projecting plate 305 is used to make room for the other structural, electrified components described above, ensuring that the plate body 301 slides only on the lower surface of the projecting plate 305. Correspondingly, the upper part of the fixing shaft 201 also needs to be provided with a cushion 203, the thickness of which is equal to that of the protruding plate 305, so as to ensure that the plate 301 is not bent vertically.

On the other hand, the direct support of the car floor b by the hover mechanism translates into 2 of said projecting plates 305, which are still "planar" and comprehensive.

The vertical shaft unit 2 further comprises a reset torsion spring 204 which is sleeved on the fixed shaft 201 and used for rotating away from the plate body 301 on the hovering plate unit 1.

In this embodiment, the number of the restoring torsion springs 204 is 2, corresponding to 2 mounting holes 302, and one end of the restoring torsion spring is inserted into the fixed shaft 201, and the other end of the restoring torsion spring is inserted into the annular surface of the mounting hole 302, so that the plate 301 is folded in a torsion trend manner.

Accordingly, a controllable jack-up structure is required to overcome the torsion force of the return torsion spring 204, and finally rotate to expand the scissor-type hovering structure, so that the exposed end of the plate 301 is fixed on the hovering plate unit 1.

The hovering plate unit 1 includes a cross plate 101 provided on the elevator shaft a, and a sloping plate 102 provided on the elevator shaft a for supporting the cross plate 101.

In this embodiment, the hovering board unit 1 is located outside the lifting operation area of the car bottom board b, and cannot interfere with the normal operation of the elevator.

The rotating plate unit 3 further includes a driving cylinder 306 provided on the lower surface of the car floor b, and a T-shaped plate 307 provided on the driving cylinder 306 and for pushing the two plate bodies 301 to rotate.

In this embodiment, the middle end of the T-shaped plate 307 is connected to the cylinder shaft of the driving cylinder 306, and the 2 protruding ends thereof respectively prop against the 2 plate bodies 301, so as to ensure that: when the driving cylinder 306 is lifted up, the 2 plate bodies 301 rotate at least by an approximate angle, and then when the driving cylinder 306 is retracted, the 2 plate bodies 301 rotate reversely by an approximate angle under the action of the reset torsion spring 204, namely, the rotation angles of the plate bodies 301 at the two sides are always approximate.

In addition, the 2 protruding ends of the T-shaped plate 307 are further provided with a roller for directly propping against the plate 301, so as to ensure that the jacking action is more labor-saving.

The rotating plate unit 3 further includes a mounting groove 308 provided on the lower surface of the protruding plate 305 for mounting the driving cylinder 306.

In this embodiment, the driving cylinders 306 are disposed in an acute angle area surrounded by 2 of the plates 301, and thus the number thereof may be 1 or 2. At this time, the mounting groove 308 is also correspondingly provided at a substantially middle position of the projecting plate 305.

On the other hand, by positioning the driving cylinder 306 at about the midpoint between the 2 plates 301, it is ensured that the driving cylinder 306 can push the 2 plates 301 substantially symmetrically, so that the 4 hovering positions of the hovering mechanism can be fully fixed and fully released simultaneously.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
