Description
Technical field
The utility model relates to the heavy tensioner of a kind of swabbing pig, is used for regulating the tension force that belt is carried swabbing pig, is applicable to various band conveyors, as used band conveyors of industry such as colliery, power plant, harbour, cement mill, grain depots.
Background technology
Existing band conveyor field mostly adopts swabbing pig that conveyer belt is carried out cleaning, is used for cleaning the material that remains on the conveyer belt, keeps the normal operation of belt.Because swabbing pig need contact with belt when cleaning, because heavy swabbing pig framing member is bigger, general model tensioner can't satisfy the tension force of this swabbing pig.The size of the tension force between swabbing pig and the belt not only can have influence on the cleanliness level of belt, also has influence on the belt maintenance.The tension force of swabbing pig and belt is too little, and cleaning is just totally not thorough, and cleanliness level is lower, but is not easy to damage conveyer belt; The tension force of swabbing pig and belt is too big, though cleanliness level improves, beat type or vibrations appear in swabbing pig easily in the use, easily cause the damage of belt.
At present also do not have to regulate the device of tension force between swabbing pig and belt, swabbing pig mixes up the relative position of swabbing pig and belt when mounted, belt is just relative definite with the tension force between the swabbing pig, can not automatically regulating in the use, as abnormal condition, damage belt easily.
The existence of above-mentioned situation has limited swabbing pig and has played a role well, because swabbing pig lacks from conditioning function, is easy to damage blade when running into obstacle in the use, and after the swabbing pig damage, maintenance maintenance is also not too convenient.
Summary of the invention
The utility model provides a kind of heavy tensioner with regulatory function at existing technology status, and the tension force between this tensioner energy automatically regulating swabbing pig and belt conveyor all plays the corresponding protection effect to sweeper blade and conveyer belt.
The purpose of this utility model realizes by following measure:
A kind of heavy tensioner, it is characterized in that it comprises carrier base 3, screw mandrel frame 4, screw mandrel 5, spring 6 and connecting lever 1, carrier base 3 comprises the plate body around sleeve and the sleeve, carrier base 3 plate bodys link to each other with screw mandrel frame 4, the end of screw mandrel 5 is installed on the screw mandrel frame 4, the same axle mounting of sleeve of connecting lever 1 front end and carrier base 3, and the rear end is sleeved on the screw mandrel 5, the top mounting spring 6 of connecting lever 1 on the screw mandrel 5, spring 6 tops are fixed by the nut that matches with screw mandrel 5.
Be provided with the bump protection ring suitable 2 in the sleeve of carrier base 3 with it.
Connecting lever 1 front end is a sleeve 7, and sleeve 7 is provided with knock hole, and connecting lever 1 rear end is connected with extension arm 8, and extension arm 8 is provided with guide groove with the position that screw mandrel 5 matches.
Screw mandrel frame 4 head ends are a flap, and the rear end is provided with mounting groove 9, and the end of screw mandrel 5 is arranged in this mounting groove 9 and by locating dowel pin 11 and connects.
Be provided with spring perch between spring 6 and connecting lever 1 guide groove.
Be sleeved on the spring 6 outer sheaths 10 that prevent dust that are set with of the head end of screw mandrel 5.
The utility model has following advantage compared to existing technology:
It is a development of technology that the utility model has from conditioning function for swabbing pig under the prior art situation substantially; the tensioner that is provided with automatically regulating function; can realize the automatically regulating of tension force between swabbing pig and belt conveyor, sweeper blade and conveyer belt are all played good protective effect.
