Detailed Description
In order to explain the technical content, the achieved objects and the effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings.
The implementation mode is as follows:
as shown in fig. 1, two-way adjustable overspeed device tensioner of industry chain, including fixed bolster 1, bolt 5, portable two-way alignment jig 2, rotation bearing roller 6, first adjusting nut 3, second adjusting nut 4, the one end fixed connection of bolt 5 is in fixed bolster 1, the other end passes first adjusting nut 3 in proper order, portable two-way alignment jig 2's through-hole and second adjusting nut 4, first adjusting nut 3, second adjusting nut 4 respectively with bolt 5 threaded connection, realize first adjusting nut 3, the position of second adjusting nut 4 on bolt 5 is adjustable, portable two-way alignment jig 2 through-hole and bolt 5 are clearance fit and connect, portable two-way alignment jig 2 can move on bolt 5. The rotating carrier roller 6 is fixedly connected to the movable bidirectional adjusting frame 2.
As shown in fig. 2, in use, the fixing bracket 1 is installed on one side of the industrial chain to be adjusted, when the upper side of the rotating carrier roller 6 abuts against the lower side of the industrial chain 7, the second adjusting nut 4 on the bolt 5 is screwed in the direction away from the movable bidirectional adjusting bracket 2, the first adjusting nut 3 on the bolt 5 is screwed, so that the first adjusting nut 3 moves in the direction away from the fixing bracket 1, the first adjusting nut 3 drives the rotating carrier roller 6 on the movable bidirectional adjusting bracket 2 to abut against the industrial chain 7, and when the industrial chain 7 reaches the expected tension, the screwing of the first adjusting nut 3 is stopped.
When the lower side of the rotating carrier roller is abutted to the lower side of the industrial chain 7, the first adjusting nut 3 on the bolt 5 is screwed in the direction close to the fixed support 1, the second adjusting nut 4 on the bolt 5 is screwed to enable the second adjusting nut 4 to move in the direction close to the fixed support 1, the second adjusting nut 4 drives the rotating carrier roller 6 on the movable bidirectional adjusting frame 2 to be abutted to the industrial chain 7, and when the industrial chain 7 reaches the expected tension degree, the second adjusting nut 4 is stopped being screwed.
The utility model discloses can realize that 7 installations of industrial chain are swift convenient, and can realize 7 two-way regulation of industrial chain, adjust the tensioning at any time through this device, guarantee 7 long-term normal operating of industrial chain.
As a preferred embodiment of the above embodiment, the number of the bolts 5, the movable bidirectional adjusting frames 2, the first adjusting nuts 3 and the second adjusting nuts 4 is 2, one end of each of the two bolts 5 is fixedly connected to the fixed bracket 1 in parallel, the other end of each of the two bolts passes through the first adjusting nut 3, the through hole of the movable bidirectional adjusting frame 2 and the second adjusting nut 4 in sequence, the first adjusting nut 3 and the second adjusting nut 4 are respectively in threaded connection with the bolts 5, the through hole of the movable bidirectional adjusting frame 2 and the bolt 5 are in clearance fit connection, and two ends of the rotating carrier roller 6 are respectively and fixedly connected to the two movable bidirectional adjusting frames 2. Through setting up two bolts 5 and portable two-way adjusting bracket 2, first adjusting nut 3, the number of second adjusting nut 4 all be 2, can make and rotate bearing roller 6 when adjusting the rate of tension of industry chain 7, more firm, it is higher to adjust the precision.
Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that modifications and improvements can be made thereto. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
