Abstract
The utility model discloses a novel driving-chain tensioning device of a paver. The novel driving-chain tensioning device comprises a fixed seat, a tensioning frame, a tensioning chain wheel, a lead screw and a fixed block, wherein the fixed seat is provided with at least one long round hole which is parallel along the axial direction of the lead screw; the tensioning frame is fixed in the long round holes of the fixed seat by fixing bolts and a pressing plate; the tensioning chain wheel is arranged in the tensioning frame by a pin shaft and a rolling bearing; the tensioning frame is provided with an ear plate for installing the lead screw; one end of the lead screw penetrates through a light hole of the ear plate and is fixed with the tensioning frame by a bolt, and the other end of the lead screw is provided with a closing nut, and penetrates through the light hole of the fixed block; and the lead screw is fixed on the fixed block by installing the tensioning nut. The novel driving-chain tensioning device disclosed by the utility model has the advantages that the phenomena that in the construction process of the axle-driven paver, the driving-chain tensioning adjustment is difficult, the wear to a chain is great, and the phenomena that the chain is impacted by force frequently and causes early break are avoided, so that the service life of the driving chain is greatly prolonged; and the operation and adjustment are simple, the tensioning effect is good and the reliability is high.
Description
Technical field
The utility model relates to a kind of paver chain drive-belt tension device, specifically is a kind of novel paver chain drive-belt tension device.
Background technique
Paver is a kind of special construction apparatus of the road-making materials such as asphalt, basic unit's Stabilized Soil material, roller-compacting concrete material that are used for paving.Its equipment is various, and the chain drive-belt tension device drives the auxiliary device of running gear as the paver bridge, has mainly influenced paver reliability in the course of the work, and then affects paver manufacturing efficiency.
At present, traditional paver chain drive-belt tension device, a kind of mode adopts lever principle, the tensioning piece directly and the chain sliding contact, this device is big to chain wear, the chain power that is hit often causes the early fracture of chain.Another kind of mode adopts the tensioning of the whole wheel of follower, need pull down tire during this device tensioning, and taking a lot of work very, time-consuming wasted great amount of manpower, and adjustable is relatively poor.
Summary of the invention
To the problem that above-mentioned existing technology exists, the utility model provides a kind of novel paver chain drive-belt tension device, and it is little, time saving and energy saving, easy to adjust to wear and tear.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of novel paver chain drive-belt tension device comprises that fixed base, tensioning frame, tension sprocket, silk shoulder and fixed block; Have at least one slotted hole on the fixed base along the leading screw parallel to an axis; Fixing bolt and pressing plate are fixed in tensioning frame in the slotted hole of reservation, and tension sprocket is installed in the tensioning frame through bearing pin and rolling bearing, and tensioning frame is provided with the otic placode that is used to install leading screw; Silk is shouldered an end and is passed the otic placode unthreaded hole and fix with bolt and tensioning frame; Silk is shouldered the other end installation and is closed imperial mother, and it is passed the fixed block unthreaded hole, tensioning nut is installed again leading screw is fixed on the fixed block.
As preferably, slotted hole is provided with two, and two slotted holes are parallel to each other.
The utility model Idle wheel adopts sprocket wheel and inner rolling bearing mode, and engagement is reliable, operates steadily; Avoided bridge to drive paver in work progress; Chain drive-belt tensioning adjustment difficulty, big to chain wear, the chain power that is hit often; Cause the phenomenon of the early fracture of chain, improved the working life of chain drive-belt greatly; Under the tensioning frame common leading role of slotted hole and pressing plate and fixing bolt above that, shoulder the traction displacement by silk, tension sprocket directly contacts with chain drive-belt; Make chain produce bigger rich degree, realize the tensioning of its chain, the operation adjustment is easy; Tension effects is good, and reliability is high.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model B is to view.
Among the figure: 1, fixed base, 2, tensioning frame, 3, tension sprocket, 4, silk shoulders, 5, close mother, 6, fixed block, 7, tensioning nut, 8, pressing plate, 9, fixing bolt.
Embodiment
To combine accompanying drawing that the utility model is described further below.
As depicted in figs. 1 and 2; The utility model novel paver chain drive-belt tension device; Comprise that fixed base 1, tensioning frame 2, tension sprocket 3, silk shoulder 4 and fixed block 6, have at least one slotted hole along leading screw 4 parallel to an axiss on fixed base 1 and tensioning frame 2 corresponding positions, fixing bolt 9 is fixed in tensioning frame 2 in the slotted hole of reservation 1 with pressing plate 8; Tension sprocket 3 is installed in the tensioning frame 2 through bearing pin and rolling bearing; Tensioning frame 2 is provided with the otic placode that is used to install leading screw 4, and silk is shouldered 4 one ends, and to pass the otic placode unthreaded hole fixing with bolt and tensioning frame 2, after silk is shouldered the installation of 4 the other ends and closed mother 5; It is passed fixed block 6 unthreaded holes, tensioning nut 7 is installed again leading screw 4 is fixed on the fixed block 6.
As preferably, slotted hole is provided with two, and two slotted holes are parallel to each other.Slotted hole can be regulated the position of tensioning frame 2 on the one hand, is used for fixing tensioning frame 2 on the one hand, and only it is fixed built on the sand with a slotted hole, and number can make manipulation process loaded down with trivial details too much, so select to offer two slotted holes.
Fixed base 1 is welded on the frame by design attitude with fixed block 6 in advance.When the need tensioning, at first loosening two fixing bolts 9 turn and close female 5 to certain distance; Turn tensioning nut 7 then clockwise, shoulder 4 plaies, under the tensioning frame 2 common leading role of slotted hole and pressing plate 8 and two fixing bolts 9 above that thereby drive silk; Shoulder 4 traction displacements by silk; Tension sprocket 3 directly contacts with chain drive-belt, makes chain produce bigger rich degree, realizes the tensioning of its chain.At last, tighten fixing bolt 9, through pressing plate 8 that tensioning frame 2 is locked, and will close mother 5 and fixed block 6 choke-outs.
The application of the utility model has improved the reliability of travelling system of spreader greatly, has promoted paver service behaviour and quality, has good social and economic benefit.
