Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-4, the roller conveyor transmission chain tensioning device comprises a roller conveyor side plate 1, a movable seat 3 and a one-way lifting mechanism 2, wherein the movable seat 3 is installed on the roller conveyor side plate 1, the one-way lifting mechanism 2 capable of being adjusted along the vertical position is installed on the movable seat 3, and the roller position can be changed by adjusting the one-way lifting mechanism 2, so that the chain transmission mechanism can be tensioned or loosened for maintenance.

The roller conveyor side plate 1 is provided with a large guide sleeve 18, the large guide sleeve 18 is adjustable in the vertical position along the roller conveyor side plate 1, the movable seat 3 is connected to the large guide sleeve 18 in a sliding mode, and a large spring 4 is arranged between the movable seat 3 and the large guide sleeve 18. In this embodiment, big uide bushing 18 still includes uide bushing base 17, uide bushing base 17 still is provided with kicking block 19, equipartition kidney hole on the uide bushing base 17 of big uide bushing 18, the waist hole position is fixed on roller conveyor curb plate 1 through construction bolt, when needing to adjust big uide bushing 18 position, loosen the bolt on the uide bushing base 17, install the adjusting bolt 8 that is used for the big uide bushing 18 of lifting along vertical position on the roller conveyor curb plate 1, in this embodiment, installation fixed regulating block 7 on the roller conveyor curb plate 1, adjusting bolt 8 is installed in fixed regulating block 7 position, and correspond kicking block 19 position, after loosening the bolt on the uide bushing base 17, adjusting bolt 8 removes the back, can jack up or transfer the kicking block 19 (can descend owing to big uide bushing 18 self dead weight promptly).

The one-way lifting mechanism 2 comprises a roller 9, a lifting strip 11, a small guide sleeve 12, a small spring 13 and a movable clamping tongue 14, wherein the small guide sleeve 12 is installed on the movable seat 3, the lifting strip 11 is connected in the small guide sleeve 12 in a sliding manner, the roller 9 is installed on the lifting strip 11, in the embodiment, a bolt can be used as a rotating shaft, after the roller 9 is installed, the tail end of the bolt is fixed by a bolt 10, clamping teeth are uniformly distributed on the lifting strip 11, a through hole is transversely formed in the small guide sleeve 12, the movable clamping tongue 14 used for clamping the clamping teeth is installed on the through hole, the small spring 13 arranged in the through hole is sleeved on the movable clamping tongue 14, the small spring 13 always generates restoring force to push the movable clamping tongue 14 to the clamping teeth at the position of the lifting strip 11 for clamping, in the embodiment, the clamping teeth on the lifting strip 11 are inclined downwards, namely, any one clamping tooth is a right triangle, and the upper side of the clamping tooth is inclined by 45 degrees, the lower side is horizontal. Correspondingly, the lower side of the head of the movable latch 14 inclines by 45 degrees, and the upper side is horizontal and can be meshed with the latch. When the lifting bar 11 moves upwards, the lifting bar 11 is directly pushed upwards, the clamping direction is downward, when the lifting bar 11 is pushed upwards, the lifting bar 11 overcomes the restoring force of the small spring 13, the lifting bar 11 needs to move downwards, the movable clamping tongue 14 is pulled to move backwards to overcome the restoring force of the small spring 13, and the movable clamping tongue 14 loosens the clamping teeth, so that the lifting bar 11 can move downwards.

The working process of the utility model is as follows: two guide rods 16 are arranged on the movable seat 3 and are matched with the inner holes on the guide machine base 5. The guide machine base 5 moves up and down by utilizing a fixed adjusting block 7 arranged on the side plate 1 of the roller conveyor and by tightly or loosely pushing a top block 19 on the guide machine base 5 through an adjusting bolt 8. The guide machine base 5 is driven to ascend or descend by the force applied to the movable base 3 by the large spring 4. Because the spring has certain elastic force, the buffer device can play a role in buffering related parts on the movable seat 3 and relieve the impact force generated by the transmission chain on the one-way tensioning mechanism. When the transmission chain is tensioned, the movable seat 3 rises to drive the roller 9 of the one-way tensioning mechanism to be tightly propped against the transmission chain, and the rough adjustment work is completed. And then according to the tightness degree of each group of transmission chains, the corresponding one-way tensioning mechanism is utilized to realize rapid lifting adjustment, so that the roller 9 on each group of one-way tensioning mechanism is ensured to be stressed consistently with the transmission chains, and finally, fine adjustment is finished. The lifting strip 11 of the one-way tensioning mechanism is provided with an inclined tooth socket, a movable clamping tongue 14 and a small spring 13 to realize the one-way movement self-locking function, so that the lifting strip 11 is prevented from falling under stress. When a certain group of transmission chains have problems in use and need to be replaced, the corresponding movable clamping tongues 14 of the one-way tensioning mechanism are pulled out of the inclined tooth grooves of the lifting strips 11, the lifting strips 11 are put down, the transmission chains can be loosened, the replacement of the damaged transmission chains is completed, then the lifting strips 11 are quickly moved upwards by hands, and the tensioning work of replacing the transmission chains is completed.
