Technical field
The utility model is related to the tensioning apparatus of huge bucket wheel machine, and in particular to a kind of Novel heavy hammer connecting rod tensioning apparatus.
Background technology
At present, with the development of penumatic capsule pipeline system industry, continuative transport machinery develops towards big production capacity direction,
The larger place of loose unpacked material handling capacity, such as the huge bucket wheel machine of production capacity 6000-10000t/h such as mine, harbour is shown in repeatly
It is not fresh.Such continuative transport machinery is generally transmitted using belt, compares general bucket wheel machine, and huge bucket wheel machine conveyer belt needs
Tensile force it is bigger, if conveyer belt tensile force not enough if easily cause sideslip to cause material spilling even to tear.Huge bucket
Turbine generally uses Hydranlic tensioner, when equipment is built, in cantilever shalving head Hydranlic tensioner is arranged, and regulates
Hydraulic means is locked after conveyer belt tensile force.But after the use of a period of time, abrasion and aging meeting cause transmission to carry
Relax, tensile force does not reach requirement, be at this moment accomplished by readjusting Hydranlic tensioner, waste time and energy.Small-sized bucket wheel machine
Tensioning apparatus is usually that conveyer belt is tensed by being connected with cylinder by the self gravitation of ballast box at cantilever shalving rear portion, but this
Method is not suitable for huge bucket wheel machine, because to reach the deadweight of the tensile force ballast box needed for huge bucket wheel machine conveyer belt very
Greatly.When ballast box deadweight is too big, in order to ensure that assembled machine balance is accomplished by the counterweight of whole machine to increase, this improves strong to steel construction
The requirement of degree, increased construction cost, lose economy, can also affect the stability of whole machine.Adjust by self gravitation and transmit
Ballast box with tensile force is typically all the activity on two guide rods that is enclosed within, and has stop device to prevent ballast box from taking off in guide rod bottom
Fall, ballast box is to the automatic compensation for having one section of activity surplus to be used as stroke of tension between stop device.When the belt of cantilever
During unexpected fracture, if ballast box deadweight is very big, potential energy is just very big, and it may be thrust when falling on stop device so as to cause
Come off, there is potential safety hazard.
In sum, existing tensioning apparatus is suffered from the drawback that：
(1) although tensioning requirement can be reached suitable for the Hydranlic tensioner of huge bucket wheel machine, tensile force is regulated
After must lock, with conveyer belt it is aging lax after can not compensate automatically, it is necessary to must readjust, waste time and energy；
(2) suitable for the gravity tension device of small-sized bucket wheel machine, although can compensate automatically, but cost increases after amplifying,
The stability of whole machine is affected, or even there is potential safety hazard, therefore be used for huge bucket wheel machine after can not amplifying.
Utility model content
For weak point present in the problems referred to above, the utility model provide it is a kind of,, solve existing huge bucket wheel machine
Hydranlic tensioner needs the problem of periodically adjustment.
For achieving the above object, the utility model provides a kind of Novel heavy hammer connecting rod tensioning apparatus, including：Weight, connecting rod
A, connecting rod B, stop device, steel wire rope, hinge, belt tensioning drum and bend pulley；
Two bend pulleys are fixed on cantilever shalving, the belt tensioning drum be fixed on two bend pulleys it
Between, two connecting rod A vertically downward are fixed on the belt tensioning drum on the cantilever shalving of centre of gyration side, and the tensioning is rolled
Cylinder two ends are respectively hinged on two connecting rod A, and one end of two connecting rod A passes through respectively two institutes of the stud connection
One end of connecting rod B is stated, the weight is fixed between the other end of two connecting rod B, the weight two ends are respectively provided with described
Stop device, and the stop device is fixed on the connecting rod B, one end of two steel wire ropes is separately fixed at described outstanding
On arm support, the other end of the other end of two steel wire ropes connecting rod B described with two respectively is fixedly connected.
Further improve as the utility model, weight bilateral reciprocation between two connecting rod B.
Further improve as the utility model, stop device bilateral reciprocation between two connecting rod B.
Further improve as the utility model, the distance of the weight to the belt tensioning drum is more than the hinge to institute
State the distance of belt tensioning drum.
The beneficial effects of the utility model are：
1st, lever principle is cleverly utilized, the tensile force applied to conveyer belt under conditions of weight deadweight is as little as possible is most
Bigization, both can ensure that the stability of whole machine, again can be with cost-effective；
2nd, the stop device and steel wire rope at weight two ends provides dual fail-safe to the slip-off preventing of weight, strengthens the peace of equipment
Quan Xing；
3rd, relative to conventional hydraulic tensioning apparatus, the ability with automatic compensation, it is not necessary to periodically hydraulic means is carried out
The tensile force for adjusting to ensure conveyer belt reaches requirement, time saving and energy saving；
4th, good economy performance, low cost, it is easy to promote.

Specific embodiment
As shown in Figure 1-2, a kind of Novel heavy hammer connecting rod tensioning apparatus of the utility model embodiment, including：Weight 1, company
Bar A, connecting rod B, stop device 4, steel wire rope 5, hinge 6, belt tensioning drum 9 and bend pulley 10.
It is have three cylinders with traditional small-sized bucket wheel machine tensioning apparatus identical, two bend pulleys 10 are fixed on cantilever
On frame 8, belt tensioning drum 9 is fixed between two bend pulleys 10.Belt tensioning drum 9 is on the cantilever shalving 8 of centre of gyration side
Two connecting rod A vertically downward are fixed, the two ends of belt tensioning drum 9 are respectively hinged on two connecting rod A, one end point of two connecting rod A
Not Tong Guo hinge 6 connect two connecting rod B one end, weight 1 is fixed between the other end of two connecting rod B.For effectively utilizes thick stick
Rod principle, it is ensured that distance of the distance of weight 1 to belt tensioning drum 9 more than hinge 6 to belt tensioning drum 9, so that conveyer belt 7
The deadweight ratio of tensile force and weight 1 is bigger.
The two ends of weight 1 are respectively provided with stop device 4, and stop device 4 is fixed on connecting rod B, prevent weight 1 from sliding and taking off
Fall, one end of two steel wire ropes 5 is separately fixed on cantilever shalving 8, the other end of two steel wire ropes 5 is respectively with two connecting rod B's
The other end is fixedly connected, and the bottom of weight 1 smashes equipment or comes off when preventing conveyer belt 7 from surprisingly rupturing, and allows device security to carry
It is high.
The bilateral reciprocation between two connecting rod B of weight 1, the reciprocal fortune in the left and right between two connecting rod B of stop device 4
It is dynamic.That is, position of the stop device 4 on connecting rod B can be regulation, while the position of weight 1 also can be regulation, so
The power that weight 1 is applied on belt tensioning drum 9 can be just adjusted, use requirement can be better met.Therefore, using weight 1 from
Weight and lever principle can be automatically compensated the stroke of tension of conveyer belt 7 during prolonged use, are reached to use and are wanted
Ask.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
