Description

Low-height short-stroke lifting mechanism and roller type conveying mechanism with steering function

Technical Field

The present utility model relates to a roller conveyor mechanism.

Background

Roller conveyor mechanisms, also commonly referred to as roller conveyor mechanisms, drive the rotation of a roller by a motor, which moves the material on the roller. Such conveying mechanisms are generally used for conveying heavy materials due to the strong supporting strength of the rollers. One disadvantage of roller conveyor mechanisms is the difficulty in turning. Since the rollers need to transmit power via a power transmission belt, the rollers are generally required to be parallel to each other, and thus, the roller conveyor mechanism is generally capable of only effecting material conveyance in a straight direction. In the production shop, the production line cannot be constructed in a straight line due to limited space in the production shop, which means that the roller type conveying mechanism corresponding to the production line needs to have steering capability. In the prior art, steering of the roller conveyor is typically achieved by providing rollers in one direction on a crane, the lifting of which is typically powered by an air cylinder or oil cylinder. On the other hand, since the material conveyed by the roller conveyor is generally of a large weight, the material conveying surface for conveying the material is generally not configured to be too high. If the roller position is set too high, the material falls and has a large safety risk, and meanwhile, the material is not convenient for staff to get on and off. Whereas a cylinder or ram powered lift typically requires a relatively high height.

Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

Fig. 1 illustrates a roller conveyor with steering, comprising a conveyor in two directions and a conveyor steering adaptation mechanism 3. The conveying mechanisms in the two directions are a first direction conveying mechanism 1 and a second direction conveying mechanism 2 respectively. The conveying mechanisms in the two directions are provided with conveying roller mechanisms, and the horizontal heights of the material conveying surfaces of the conveying mechanisms in the two directions are different. In this embodiment, the horizontal height of the material conveying surface of the second direction conveying mechanism 2 is higher than that of the first direction conveying mechanism 1, and the material conveying directions of the first direction conveying mechanism 1 and the second direction conveying mechanism 2 are perpendicular. The conveying steering adapting mechanism 3 is arranged at the joint of the first direction conveying mechanism 1 and the second direction conveying mechanism 2, and is respectively connected with the conveying mechanisms in two directions. The conveying steering adapting mechanism 3 comprises two sets of conveying roller mechanisms. The two sets of conveying roller mechanisms are a first conveying roller mechanism 31 and a second conveying roller mechanism 32, respectively. The first conveying roller mechanism 31 and the second conveying roller mechanism 32 are each provided with a power mechanism. Specifically, the first conveying roller mechanism 31 is connected to the first power mechanism 311, and the second conveying roller mechanism 32 is connected to the second power mechanism 321. The two sets of conveying roller mechanisms are respectively butted with the conveying mechanisms in two directions. Specifically, the first conveying roller mechanism 31 is abutted against the first direction conveying mechanism 1, and the second conveying roller mechanism 32 is abutted against the second direction conveying mechanism 2. Referring to fig. 2 and 3, the first conveying roller mechanism 31 is fixed to the frame of the conveying direction changing adapting mechanism 3, and is engaged with and at the same height as the material conveying surface of the conveying mechanism whose material conveying surface height is lower. In this embodiment, the conveying mechanism with a lower material conveying surface is the first direction conveying mechanism 1. That is, the first conveying roller mechanism 31 is the same height as the material conveying surface of the first direction conveying mechanism 1, and the first conveying roller mechanism 31 is engaged with the first direction conveying mechanism 1. The second conveying roller mechanism 32 is provided on the low-height short-stroke elevating mechanism 300, more specifically, the second conveying roller mechanism 32 is provided on the elevating frame 33 of the low-height short-stroke elevating mechanism 300.

The low-height short-stroke elevating mechanism 300, referring to fig. 3 and 4, includes an elevating frame 33 and a jacking mechanism 34 connected to the elevating frame 33. The lifting frame 33 can vertically lift under the limiting and guiding actions of four side frames of the frame of the conveying steering adapting mechanism 3. The jacking mechanism 34 includes a roller 331 provided at the bottom of the lifting frame 33, a translational jacking guide frame, and a lifting drive cylinder 342. The translational lifting guide frame comprises a translational lifting slide plate 341 arranged in the chute and a lifting driving cylinder 342 connected with the translational lifting slide plate 341. Horizontally arranged. The lift cylinder 342 may be a cylinder or an oil cylinder, and in this embodiment, the lift cylinder 342 is preferably a cylinder. The elevation driving cylinder 342 is horizontally disposed, that is, the piston of the elevation driving cylinder 342 is horizontally moved, thereby enabling the translational jack-up slide 341 connected to the elevation driving cylinder 342 to be horizontally moved in the slide groove along the length direction of the translational jack-up slide 341 under the driving of the elevation driving cylinder 342. The translational jack slide 341 is provided with a bevel groove 3411. The roller 331 is disposed at the bottom of the lifting frame 33 through a roller seat 332, and a bearing is provided between the roller 331 and the roller seat 332 such that the roller 331 can rotate along the axis of the horizontal shaft. The axis of the roller 331 is horizontal and perpendicular to the length direction of the translational jack-up sliding plate 341. The position of roller 331 matches the position of ramp slot 3411 such that roller 331 can roll into ramp slot 3411 or out of ramp slot 3411 as translating jack-up slide 341 moves horizontally. Referring to fig. 5, when the translational jack-up slide 341 is moved in the direction indicated by the arrow M by the driving of the elevation driving cylinder 342, the roller 331 in the inclined surface groove 3411 can roll along the inclined surface of the inclined surface groove 3411 and finally roll out of the inclined surface groove 3411, in which process the translational jack-up slide 341 plays a role in lifting up the roller 331 and lifts the lifting frame 33 above the roller 331 to the highest point when the roller 331 rolls out of the inclined surface groove 3411, and when the translational jack-up slide 341 is moved in the direction opposite to the direction indicated by the arrow M by the driving of the elevation driving cylinder 342, the roller 331 outside the inclined surface groove 3411 can roll along the inclined surface of the inclined surface groove 3411 and roll into the inclined surface groove 3411 and finally roll to the lowest point of the inclined surface groove 3411, in which process the lifting frame 33 above the roller 331 naturally falls under the action of its own weight, so that the lifting frame 33 falls to the lowest point when the roller 331 rolls out of the lowest point of the inclined surface groove 3411.

When the lifting frame 33 is lifted to the highest point, the material conveying surface height of the second conveying roller mechanism 32 arranged on the lifting frame 33 is higher than that of the first conveying roller mechanism 31 fixed on the frame and is the same as that of the conveying mechanism with the higher material conveying surface height, so that the second conveying roller mechanism 32 on the lifting frame 33 is engaged with the conveying mechanism with the higher material conveying surface height. In this embodiment, the conveying mechanism with a higher material conveying surface is the second direction conveying mechanism 2. That is, when the lifting frame 33 is lifted to the highest point, the material conveying surface of the second conveying roller mechanism 32 is flush with the second direction conveying mechanism 2, and thus, the second conveying roller mechanism 32 is engaged with the second conveying mechanism 2.

The working principle of the embodiment is that when the second conveying roller mechanism 32 is lowered to the lowest point, the height of the second conveying roller mechanism 32 is lower than that of the first conveying roller mechanism 31, at this time, through the engagement between the first conveying roller mechanism 31 and the first direction conveying mechanism 1, the materials on the first direction conveying mechanism 1 can move to the conveying steering adapting mechanism 3, the materials on the conveying steering adapting mechanism 3 can also move to the first direction conveying mechanism 1, and the second conveying roller mechanism 32 with the height lower than that of the first conveying roller mechanism 31 cannot cause obstruction to the conveying of the materials between the conveying steering adapting mechanism 3 and the first direction conveying mechanism 1. When the second conveying roller mechanism 32 is lifted to the highest point, the height of the second conveying roller mechanism 32 is higher than that of the first conveying roller mechanism 31, at this time, the materials on the second conveying mechanism 2 can move to the conveying steering adaptation mechanism 3 through the engagement between the second conveying roller mechanism 32 and the second conveying mechanism 2, the materials on the conveying steering adaptation mechanism 3 can also move to the second conveying mechanism 2, and the first conveying roller mechanism 31 with the height lower than that of the second conveying roller mechanism 32 cannot cause obstruction to the conveying of the materials between the conveying steering adaptation mechanism 3 and the second conveying mechanism 2. When the material is required to be transferred from the first direction conveying mechanism 1 to the second direction conveying mechanism 2, the second conveying roller mechanism 32 is firstly lowered to the lowest point, then the material is moved from the first direction conveying mechanism 1 to the conveying steering adapting mechanism 3, at the moment, the material on the conveying steering adapting mechanism 3 is supported by the first conveying roller mechanism 31, then the second conveying roller mechanism 32 is lifted to the highest point, so that the material is supported by the second conveying roller mechanism 32, and finally the material on the conveying steering adapting mechanism 3 is conveyed to the second direction conveying mechanism 2. When the material needs to be transferred from the second direction conveying mechanism 2 to the first direction conveying mechanism 1, the specific process is opposite to the above, and will not be repeated.

In addition, in order to enable the second conveying roller mechanism 32 to be lifted and lowered smoothly, in this embodiment, two translational jack-up slides 341 are provided, and two inclined grooves 3411 are provided on the translational jack-up slide 341. The two translational jack-up slides 341 are parallel to each other and are respectively located below two sides of the lifting frame 33. The two translation jacking slide plates 341 are connected through a synchronous translation frame 343, and are connected with a lifting driving cylinder 342 through the synchronous translation frame 343.

In alternative embodiments, the translational lift slide 341 may be configured with three, four, or more. There may be three, four or more ramp grooves 3411 provided on the translating jack-up slide 341. At this time, the translational jack-up slides 341 are parallel to each other, and the translational jack-up slides 341 are connected to each other by a synchronous translational frame 343.

In addition, to provide less friction when the translating jack-up slide 341 translates within the chute, the translating jack-up slide 341 is mounted on a rollable mechanism. In the embodiment, referring to fig. 4, the slide groove is constructed of a roller groove bracket 344, and the roller groove bracket 344 includes a bracket plate 3441 and a roller round bar 3442. The bracket plate 3441 has two pieces. The two support plates 3441 are vertically disposed, parallel to each other, and disposed along the length direction of the translational jack-up slide 341. A certain gap is left between the two support plates 3441. The rolling round bar 3442 is provided between the two holder plates 3441. The rolling round rod 3442 and the bracket plate 3441 are connected through a bearing. When the translational jack-up sliding plate 341 is arranged on the roller bar groove bracket 344, the bottom of the translational jack-up sliding plate 341 is erected on the rolling round bar 3442, is supported by the rolling round bar 3442 and is clamped by the two support plates 3441. Note that, in the present embodiment, the slide groove is constructed by two roller groove brackets 344, and the two roller groove brackets 344 are respectively disposed at both ends of the translational jack slide 341 in the longitudinal direction, and each roller groove bracket 344 is provided with two rolling round bars 3442. Those skilled in the art will appreciate that the roller bar slot brackets 344, which are constructed as a runner, may be three, four or more, or even one. It is apparent that when there is one roller bar groove bracket 344 constituting the slide groove, at least two roller round bars 3442 are required on the roller bar groove bracket 344.

In another alternative embodiment, the sliding chute may implement rolling movement of the translational jack slide 341 by two mutually parallel carriage plates cooperating with balls.

In addition, to reduce the power required to raise and lower the lift frame 33 by the lift drive cylinder 342, the inclined surface of the inclined surface groove 3411 is generally inclined at an angle of not more than 30 degrees to the horizontal.
