Abstract
The utility model discloses an oil-free lubrication wind-resisting type weight limit frame comprising two vertical guide pipes which are fixed on a support column through a support mechanism. The two guide pipes are respectively arranged on the left side and the right side of a weight. One group or more than two groups of weight skewing limit mechanisms are arranged between the two guide pipes and the weight. The weight skewing limit mechanisms comprise weight hoops, the left side and the right side of each weight hoop are fixedly connected with guide wheel mounting supports. The two guide wheel mounting supports are respectively fixed with two guide wheel shafts. A guide wheel is arranged on each guide wheel shaft through an oil-free lubrication bearing. The guide pipes penetrate through two corresponding guide wheels. The oil-free lubrication wind-resisting type weight limit frame solves the problems that the sliding wheel is jammed, and the integral structure is unstable due to the fact that the sliding wheel and the guide pipes are arranged on the same side of the weight, and has a great limit function to swinging of the weight.

The quantity of weighing down stone roller offset-limited mechanism is two.
The both ends of each guide wheel shaft are processed with screw thread, and captive joint with the track adjusting wheel erecting frame through captive nut.
On each guide wheel shaft and the both ends that are positioned at corresponding track adjusting wheel are provided with baffle plate, and each baffle plate is captiveed joint with track adjusting wheel through flathead screw.
The quantity of bracket institution is two and all is connected with the end of two conduits, and two bracket institutions include limit bracket and the thrust block and corresponding that level is connected on the pillar and are connected the diagonal brace angle steel between limit bracket and the thrust block.
Be connected with the catheter position control apparatus between bracket institution and the conduit.
Each catheter position control apparatus includes rack connecting plate and regulating plate; Each rack connecting plate level is to being fixed on the bracket institution and having mounting hole; Each regulating plate level is to being fixed on the conduit and having the vertical equity slotted hole, captives joint through on mounting hole and slotted hole, tie bolt being set between cooresponding rack connecting plate and the regulating plate.
The beneficial effect that the utility model oil-free lubrication wind-proof weighs down stone roller restriction frame is: the left and right sides weighing down stone roller is respectively arranged with conduit; Adopting the guiding of DLC ways to restrain to weigh down stone roller moves up and down; And between guide wheel shaft and track adjusting wheel, Nonlubricated bearing is installed; Thereby thereby good fixing effect, stability is high, weighs down that stone roller can not be swung when meeting high wind, bump, clamping stagnation and deflection.

The specific embodiment
As depicted in figs. 1 and 2, the utility model oil-free lubrication wind-proof weighs down stone roller restriction frame, comprises the conduit 5 that is fixed on two vertical directions on the pillar 1 through bracket institution.Weigh down the left and right sides that stone roller 9 is positioned at two conduits 5; Two conduits 5 and weigh down and be provided with one group or two groups of above stone roller offset-limited mechanisms of weighing down between the stone roller 9; Weigh down stone roller offset-limited mechanism and comprise and weigh down stone roller anchor ear 7, the left and right sides of weighing down stone roller anchor ear 7 is fixed with two guide wheel shafts 10 before and after being fixedly connected with on 15, two track adjusting wheel erecting frames 15 of track adjusting wheel erecting frame all respectively; All through Nonlubricated bearing 11 8, two conduits 5 of track adjusting wheel being installed on two guide wheel shafts 10 passes between cooresponding two track adjusting wheels 8.
In the present embodiment, the quantity of weighing down stone roller offset-limited mechanism is two.
The both ends of each guide wheel shaft 10 are processed with screw thread, and captive joint with track adjusting wheel erecting frame 15 through captive nut 14.On each guide wheel shaft 10 and both ends that are positioned at corresponding track adjusting wheel 8 are provided with baffle plate 12, and each baffle plate 12 is captiveed joint with track adjusting wheel 8 through flathead screw 13.
The quantity of bracket institution is two, and bracket institution all is connected with two ends up and down of two conduits 5.Wherein, two bracket institutions include limit bracket 2 and the thrust block 3 and corresponding that level is connected on the pillar 1 and are connected the diagonal brace angle steel 4 between limit bracket 2 and the thrust block 3.Limit bracket 2, thrust block 3 and diagonal brace angle steel 4 are formed the trigonometric expression supporting construction, support reliable and stable.
In order to make conduit 5 keep vertically being connected with catheter position control apparatus 6 between bracket institution and the conduit 5.Each catheter position control apparatus 6 includes rack connecting plate 6-1 and regulating plate 6-2; Each rack connecting plate 6-1 level is to being fixed on the bracket institution and having mounting hole; Each regulating plate 6-2 level is to being fixed on the conduit 5 and having the vertical equity slotted hole, captives joint through on mounting hole and slotted hole, tie bolt being set between cooresponding rack connecting plate 6-1 and the regulating plate 6-2.Through the rack connecting plate 6-1 at adjusting conduit two ends about in the of 5 and the relative position between the regulating plate 6-2, conduit 5 is kept vertically.
The principle of work of the utility model is: when thread tension force changes, weighs down stone roller 9 and can move along conduit 5 easy on and off, owing to be friction of rolling between conduit 5 and the track adjusting wheel 10, so the little rolling of friction force is freely.Two conduits 5 are separately positioned on the left and right sides of weighing down stone roller 9, and every group weighed down in the stone roller offset-limited mechanism, and each conduit 5 all passes between cooresponding two track adjusting wheels 8, and therefore, weighing down stone roller 9 can be owing to the monolateral stressed phenomenon that deflection takes place.
