Belt tensioning mechanism is component part important in belt feeder system, it is therefore an objective to provide suitable preload for belt
Power guarantees the normal operation of belt.For compact-sized belt feeder system, driving roller and belt tensioning drum are merged, tensioning
Roller is to drive roller, and tensioning apparatus is made of hydraulic system, lead screw, tensioning trolley, driving roller and driving unit, is driven
Roller and driving unit are mounted on tensioning trolley.Hydraulic system provides pulling force, and tensioning trundle group is moved along guide rail direction,
When belt reaches target pretightning force, lead screw is locked with nut.Wherein, being tensioned trundle group and the contact surface of guide rail has two
Face.
Currently, tensioning trundle group and the contact surface of guide rail only have two sides, rigidity is poor, and be easy to cause single side stress compared with
Greatly, abrasion is very fast；Driving unit is mounted on tensioning trolley, and rigidity is lower, stability is poor, therefore causes tensioning trolley vibration
Seriously, the connection between each component is influenced, the service life of equipment is reduced.
Summary of the invention
In order to solve above-mentioned the technical problems existing in the prior art, the application has mentioned a kind of compact coal conveyer belt
Tight device.
To realize the purpose of this utility model, the utility model provides a kind of compact coal conveyer stretcher,
Including heavy oriented module mechanism and four-bar mechanism, the heavy type oriented module mechanism includes guide rail and sliding block, the sliding block
It is slided in guide rail, the four-bar linkage structure includes belt feeder ontology, first connecting rod, second connecting rod and tensioning trolley；First connects
Bar and belt feeder ontology pass through stud connection；Second connecting rod and first connecting rod pass through stud connection；Driving unit, driving roller and
Tensioning trolley is integral structure, and second connecting rod and driving unit pass through stud connection；It is tensioned trolley and passes through sliding block, guide rail and skin
Band machine ontology connects.
Wherein, the sliding block lower end is provided with notched rectangular cavity, and the upper end of the guide rail is and the rectangular cavity phase
Four faces of the square block being used cooperatively, the rectangular cavity are slidably connected with the square block.
Wherein, including hydraulic cylinder, the hydraulic cylinder are arranged on belt feeder ontology, and piston rod and tensioning trolley connect
It connects.
Wherein, including lead screw, the lead screw pass through the belt feeder ontology, and one end connect with the tensioning trolley, reaches
When pre-tightening force request to belt, lead screw and belt feeder ontology are locked with two nuts.
Compared with prior art, the beneficial effects of the utility model are,
1) rigidity for increasing strainer ensure that the linear motion of the device；
2) stability for improving driving unit offsets the part vibration of the unit, guarantees the service life of equipment.
