Description
Technical field
The present invention relates to a kind of structures for being used to support steel wire rope rope closing and putting rope, and in particular to a kind of cable rack assembly,
Belong to forestry machinery field.
Background technology
Domestic skidder when operation, needs to bundle log with steel wire rope and hook, then in forest at present
It carries out traction and is drawn to destination.Steel wire rope need to be supported through cable rack, and cable rack is equivalent to pulley, and steel wire rope, which can pass through, to be slided
Wheel carrys out hoisting heavy.After the hook of steel wire rope hangs up properly log, when rope closing, steel wire rope just drastically loads, and steel wire tensioning is exceptionally straight, steel
The log bundled can be pulled to the tail portion of skidder, and appropriate boom hoist cable by pulling force by cord, ensure one end of log
It does not land, and leans against on machine, the other end lands, and moves forward to be drawn by complete machine.When complete machine is in Turning travel process
In, steel wire rope can occur with cable rack being the sliding of support left and right because of the steering of log, but cannot allow steel wire rope clamping stagnation again.One
Denier skidding distance is excessive, and steel wire rope is just easy to happen clamping stagnation, it is difficult to return, while steel wire rope surface can be damaged, it just influences entire
The effect pulled is drawn, while influencing service life of steel wire rope.Therefore, for the cable rack that steel wire rope plays a supportive role become for
Very crucial structural assembly, traction working condition are different from the steel wire rope of crane, the steel wire rope of crane for steel wire rope
The weight of lifting does not land completely, and the operating mode log of skidder only has one end not land, and the other end lands completely, and steel wire rope exists
Rope closing and while putting rope, should ensure, completely or nearly in pure rolling, to allow steel wire rope or so sliding motion again, while reducing it
Abrasion.It is thus more complicated for the requirement of the support construction of steel wire rope, lack such structural assembly at present.

3. bushing can prevent high-speed rotating second axis pin in axial float, inside plate surface is destroyed, axial direction is played
Position-limiting action improves functional reliability to extend the service life of cable rack.
4. the cable rack assembly maintenance cost of the present invention is low, after length of steel rope time heavy duty work, it is likely to result in peace
Bolt looseness is filled, it can convenient pretension bolt by the service hatch on side plate.
5. cable rack assembly of the present invention can reduce the abrasion of steel wire rope, extend the service life of steel wire rope, reduce use at
This.
6. working efficiency is higher, since this construction reduce the clamping stagnations of steel wire rope, and can self-return, therefore operational stoppage
Time shortens, and efficiency improves.
7. the installation and removal of cable rack assembly are more convenient.

Specific implementation mode
The present invention will be further described with reference to the accompanying drawings.
As depicted in figs. 1 and 2, a kind of cable rack assembly of the present invention includes the second axis pin 7 of supporting steel-cable movement, branch
The first axis pin 6 of the second axis pin 7 is supportted, supports the cable rack of the first axis pin 6, the second axis pin 7 that can be rotated relative to cable rack, steel wire rope
It is pressed on the second axis pin 7, and across the space that cable rack and the second axis pin 7 limit, carries out folding and unfolding operation.Wherein, cable rack
A kind of implementation is classified as, the rigid frame structure connected by upper plate 2, lower plate 4 and two pieces of interior plates 3.4 both ends of upper plate 2 and lower plate
It is welded with side plate 1, fixed block 5 is welded on interior plate 3.
On the basis of the said structure, as shown in figure 3, the both ends of the second axis pin 7 are respectively fitted with axle sleeve 12, in axle sleeve 12
One end is equipped with oil sealing 11.As shown in figure 4, there is stepped hole on cable rack interior plate 3, it is equipped on stepped hole to the second axis pin
The bushing 10 of 7 limits.Bushing can prevent high-speed rotating second axis pin in axial float, destroy inside plate surface, play
Axial limiting acts on, and to extend the service life of cable rack, improves functional reliability.
First axis pin 6 of the invention has the oil duct that can fill and store lubricating oil, table in the axle sleeve 12 contacted with the first axis pin 6
Face has the oil duct and oil groove of storage lubricating oil.First axis pin, 6 both ends are mounted on the fixation of cable rack by baffle 8 and bolt 9
On block 5, in the hole of the projection portion insertion baffle 8 at 6 both ends of the first axis pin.The present invention is equipped on side plate 1 for pacifying installation and dismantling
The service hatch unloaded is equipped with the threaded hole for dismantling bushing 10 on interior plate 3.
In addition, the second axis pin 7 of the invention is variable cross-section cylinder, cross-sectional diameter is gradually reduced from both ends to centre, the
The variable cross-section cylindrical shape of two axis pins 7 can reduce the lateral displacement of steel wire rope, to prevent steel cable sliding amplitude is excessive from leading
Cause card rope phenomenon in operation process.As shown in figure 5, being additionally provided with the fluting for accommodating steel wire rope in upper plate 2 of the present invention, lower plate 4.
When assembly, first by the assembly of bushing 10 in the stepped hole of cable rack interior plate 3, it is axial fixed to be carried out using step
Position, then axle sleeve 12 and oil sealing 11 are respectively assembled in the second axis pin 7, it is limited, is assembled using the step of the second axis pin 7
Between the second axis pin 7 is placed on two interior plates 3 of cable rack afterwards, then the assembly of the first axis pin 6 is carried out, successively by the first axis pin 6
Across the side plate 1 of cable rack, interior plate 3, the second axis pin 7.After the first axis pin 6 assembles, baffle 8 is stuck in the first pin
On 6 boss of axis, after being rotated further by baffle 8 to location hole and 5 centering of fixed block, simultaneously pretension bolt 9 is installed.It can be completed entire
The assembly of assembly.
It after steel wire tensioning is exceptionally straight, is pressed on the second axis pin 7, when rope closing is with rope is put, the second axis pin 7 is with around the first axis pin
The mode of 6 rotations realizes that pure rolling of the steel wire rope on the second axis pin 7, i.e. steel wire rope move simultaneously with the second axis pin 7, to real
Existing rope closing acts and puts rope action.When complete machine Turning travel, steel wire rope can be appeared in the steering of log on the second axis pin 7
To turning to a Slideslip, and the variable cross-section cylindrical structure of the second axis pin 7 can form certain reaction force, to limit steel wire
The sliding amplitude of rope is excessive, and after steering reversal, steel wire rope is also due to arc structure self-aligning.The configuration of the present invention is simple,
Installation, dismounting and all very convenient, the good manufacturability of repair, easily manufactured, functional reliability is good, and steel rope abrasion is small, working efficiency
It is high.Total it is of low cost.
Certainly, above-described embodiment is only the preferred embodiment of the present invention, is specifically not limited thereto, on this basis can basis
Actual needs is made with targetedly adjusting, to obtain different embodiments.Since mode in the cards is more, this
In just no longer illustrate one by one.
