Specific embodiment
Embodiment
As shown in fig. 1, the telescopic arm crane wirerope 2 ' of not set the present embodiment is directly connected to from elevator 4 flexible
The arm head pulley of 1 other end of boom, and install around and connect by arm head pulley with suspension hook, reach longer in telescoping boom semi-girder in this way
When length, the wirerope between arm head pulley and elevator is almost straightened and exists the case where perpendicular to reel, and wirerope exists at this time
Lack lateral force during winding row's rope, when elevator being easy to cause to recycle wirerope, will appear rope climbing situation at row's rope edge.
Referring again to Fig. 1, the present embodiment is in telescopic arm crane on telescoping boom 1 between elevator 4 and arm head pulley
Rope guide wheel mechanism 3 is pressed in installation, and the wirerope 2 on elevator 4, again with arm head pulley solderless wrapped connection, passes through pressure after pressure rope guide wheel mechanism 3
Rope guide wheel mechanism 3 prevents rope climbing occur in wirerope wrapup procedure.
Specifically, the pressure rope guide wheel mechanism 3 includes bracket 31, pulley spindle 32, conductor rope pulley 33, support rope rolling axle 34, support
Rope roller 35, snap-gauge 36 and self-lubricating bearing 37.
Wherein bracket 31 is the mounting bracket of entire pressure rope guide wheel mechanism 3, and using u-bracket, conductor rope pulley 33 is equipped with certainly
It lubricates bearing 37 and is locked by screw, conductor rope pulley 33 is sleeved on pulley spindle 32 by self-lubricating bearing 37, pulley spindle 32
Both ends by 36 positioning support of snap-gauge on bracket 31, conductor rope pulley 33 may be implemented on pulley spindle 32 in self-lubricating bearing 37
While being freely rotated, the thickness of conductor rope pulley 33 can also be greater than along the axial sliding of pulley spindle 32, the axial length of pulley spindle 32
Degree, to guarantee the space that slides axially of conductor rope pulley 33.Limited block is set close to the position of 31 inside of bracket in pulley spindle 32, is prevented
The only sliding of conductor rope pulley 33 collides with bracket.
Support rope roller 35 is mounted on bracket 31 by support rope rolling axle 34, and support rope rolling axle 34 is parallel with pulley spindle 32,
And both ends equally pass through 36 positioning support of snap-gauge on bracket 31, and support rope 35 turning set of roller is on support rope rolling axle 34.
Wherein support rope roller 35 uses cylindrical roll, and conductor rope pulley 33 uses sheave, and wirerope 2 passes through support rope 35 surface of roller and conductor rope is sliding
Gap between the race of wheel 33, the gap between the outer cylinder surface of support rope roller 35 and the wheel trench bottom of conductor rope pulley 33 are big
In the diameter of wirerope, while the gap at the top of the outer cylinder surface of rope roller 35 and the race of conductor rope pulley 33 being ask to be less than steel wire
The diameter of rope avoids wirerope from running out of from conductor rope pulley 33.
Support rope 35 rolling assembling of roller, during wirerope folding and unfolding passes through conductor rope pulley 33, support rope roller 35 passes through
Rotation reduces abrasion of the wirerope to support rope roller 35.The present embodiment is machined with oil filler point 38, oiling on support rope rolling axle 34
The pouring orifice in hole 38 is located at the end face of support rope rolling axle 34, and the other end extends to support rope roller inner periphery and support rope rolling axle outer circle
Between week, it can be directly injected into lubricating oil by oil filler point in the case where not dismantling support rope roller 35, be sealed after oiling by lubricating cup.
Mostly equipped with two sets of hoisting systems of master winch and secondary elevator, this implementation exists telescopic arm crane in practical application
Two groups of conductor rope pulleys 33 and two groups of support rope rollers 35, two groups of mutually matched conductor rope pulleys 33 and support rope roller are fixed on bracket 31
Distribution up and down between wheel 35 respectively corresponds the master winch steel wire rope and secondary winding steel wire rope of telescopic arm crane.
It is lifted by crane since telescoping boom 1 often stretches out, it is real in order to guarantee the stability of pressure rope 3 position of guide wheel mechanism
In the application of border basic arm joint should be mounted on by the u-bracket of bracket 31 is horizontal by the basic arm joint of pressure rope guide wheel mechanism 3
On, that is, the large arm being directly connected to Crane body, bottom plate be fixedly connected in basic arm joint, in order to guarantee that conductor rope is sliding
Wheel 33 still is able to provide necessary lateral force to wirerope 2 when being slid onto extreme position, it shall be guaranteed that the inner width both ends of u-bracket
Position is located on the inside of the wirerope of straight condition, can guarantee that wirerope 2 is being rolled up between elevator both ends and arm head pulley in this way
When raising 4 end positions winding, the lateral force of inwardly row's rope can be generated to wirerope.
The advantages of embodiment above describes the basic principles and main features of the utility model and the utility model, current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the concrete operating principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, this reality
It will also have various changes and improvements with novel, these various changes and improvements fall within the scope of the claimed invention, this
