Description

Technical Field

[0001] The utility model particularly relates to an adjusting idler structure. Background Art

[0002] With the development of the Internet and the increasing living standards of people, people's dependence on online shopping has gradually increased. Online shopping is inseparable from the logistics of goods, and warehouse management, as the first step of logistics, has become increasingly important. In modern warehouse management, in order to solve the problem of efficient warehouse transportation management of goods within a specified space, shelves are introduced. Shelves are like databases. When used properly, shelves can reasonably distinguish and store goods. Among them, the stacker, which plays a role similar to a porter in a database, can efficiently pick up goods from the shelves and transport them out. The stacker is efficient because its load platform uses a fork plate similar to that of a forklift to automatically pick up goods. In order for the fork plate motor to work better, it is necessary to adjust the tightness of the drive chain of the fork plate motor according to the weight of the load or the speed of picking up goods. The existing method for adjusting the chain is to simply press the idler by screwing the screw and the sprocket tension block tightly, and the state of keeping the end of the screw pressing the idler depends on the threaded connection between the screw and the sprocket tension block. When the screw is used repeatedly for many times, the threaded connection may be worn during use, thereby reducing the connection strength between the screw and the sprocket tension block. Then, the screw may become loose, thus affecting the pressing effect on the idler. Summary of the Utility Model

A left adjusting guide rod 57 and a right adjusting guide rod 58 are hingedly provided on the adjusting base plate 52; the left adjusting guide rod 57 and the right adjusting guide rod 58 are cross-sleeved on the tension rod 551 for tensioning the tension rod 551.

[0031] Further, a locking member 553 is threadedly connected to the tension rod 551. By screwing the locking member 553, the left adjusting guide rod 57 and the right adjusting guide rod 58 can be driven to approach or move away from the sprocket tension block 51.

[0032] Further, a left adjusting guide rod chute 571 is provided on the left adjusting guide rod 57, a right adjusting guide rod chute 581 is provided on the right adjusting guide rod 58, and one end of the tension rod 551 passes through the left adjusting guide rod chute 571 and the right adjusting guide rod chute 581 and is connected to the locking member 553.

[0033] Further, adjusting guide rod protrusions 572 are provided on both the left adjusting guide rod 57 and the right adjusting guide rod 58, and arc-shaped guide grooves 521 for sliding cooperation with the adjusting guide rod protrusions 572 are provided on the adjusting base plate 52.

[0034] Further, the adjusting base plate 52 can be fixed to the sprocket tension block 51 by bolts.

[0035] Further, adjusting base plate protrusions 524 for rotatably connecting with the left adjusting guide rod 57 and the right adjusting guide rod 58 are respectively provided on both sides of the adjusting base plate 52.

[0036] Further, a protrusion cushion block 523 is sleeved on the adjusting base plate protrusion 524.

[0037] Further, an adjusting screw nut 561 is sleeved on the adjusting screw 56. After the adjusting screw 56 is connected to the sprocket tension block 51, the adjusting screw nut 561 abuts against the upper end of the sprocket tension block 51.

[0038] The working principle of the present utility model is:

[0039] As Embodiment 1, as Figure 7As shown in the figure, 2 is the fork plate motor, and 4 is the drive chain. The sprocket tension block 51 is installed on the lower fork plate 1. After installation, the idler pulley 55 is located below the chain. During adjustment, since one end of the adjusting screw 56 extends into the sprocket tension block chute 511, when the adjusting screw 56 is threadedly connected to the sprocket tension block 51, turning the adjusting screw 56 downward causes the end of the adjusting screw 56 to press against the tension rod 551. On this basis, in order to enhance the stability of the tension rod 551, the present application designs a tensioning structure, and the design principle is as follows: The left adjusting guide rod 57 is alternately sleeved on the tension rod 551 through the left adjusting guide rod chute 571, and the right adjusting guide rod 58 is alternately sleeved on the tension rod 551 through the right adjusting guide rod chute 581. When the tension rod 551 moves to the specified height, turn the locking member 553. Since the locking member 553 is threadedly connected to the tension rod 551, and the left adjusting guide rod 57 and the right adjusting guide rod 58 are located between the locking member 553 and the sprocket tension block 51, when the locking member 553 is screwed into the tension rod 551, it will push the left adjusting guide rod 57 and the right adjusting guide rod 58 to closely adhere to the sprocket tension block 51. In order to reduce wear between the left adjusting guide rod 57 and the right adjusting guide rod 58, a tension rod gasket 552 is provided between the left adjusting guide rod 57 and the right adjusting guide rod 58; the state of tightening the locking member 553 is as Figure 1 shown. It can be seen from the figure that the left adjusting guide rod 57 has a left-side upward supporting effect on the tension rod 551, and the right adjusting guide rod 58 has a right-side upward supporting effect on the tension rod 551; then at this time, the tension rod 551 has both the downward pressing effect of the adjusting screw 56 and the upward supporting effect, so the tension rod 551 can maintain a stable state, and the idler pulley 55 is connected to the tension rod 551, so the idler pulley 55 has good stability and can adjust the drive chain to a stable state.

[0040] In actual operation, it is often necessary to adjust the tightness according to the scenario of chain transmission, that is, the height of the idler pulley 55 used to adjust the chain will change; taking the idler pulley 55 in Figure 1 as the initial height, when it is necessary to lower the height of the idler pulley 55, first loosen the locking member 553 and move the tension rod 551 downward. At this time, the end of the tension rod 551 will move downward along the left adjusting guide rod chute 571 and the right adjusting guide rod chute 581, and the left adjusting guide rod 57 and the right adjusting guide rod 58 will respectively rotate around the corresponding adjusting guide rod convex column 572, and the adjusting substrate convex column 524 will move along the arc-shaped guide groove 521. When the tension rod 551 moves downward to the specified height, tighten the locking member 553, then the locking member 553 fixes the left adjusting guide rod 57 and the right adjusting guide rod 58 on the tension rod 551, so that the tension rod 551 is maintained at the specified height, and the idler pulley 55 is connected to the tension rod 551, so the height of the idler pulley 55 can be adjusted.

[0041] In the above technology, the adjustment substrate 52 can be fixed to the sprocket tension block 51 by bolts. In order to prevent the left adjustment guide rod 57 and the right adjustment guide rod 58 from wearing the adjustment substrate stud 524 during the rotation relative to the adjustment substrate stud 524, it is preferable to sleeved with a stud spacer 523 on the adjustment substrate stud 524. On this basis, a tension rod spacer 552 can also be sleeved on the tension rod 551 to reduce the wear between the locking member 553 and the right adjustment guide rod 58. As an example 1, the locking member 553 can be realized by a tension rod 551 nut.
