Abstract
The invention relates to a stable brake for an elevator hoist rope. Two or more hoist ropes are available, are stretched longitudinally, are parallel to each other and are in linear arrangement, the brake comprises two parallel clamping boards, and a power device which is connected with the clamping boards and is used for pushing the two clamping boards to get close to each other; the stable brake is characterized in that the opposite sides of the two clamping boards are respectively a clamping surface, one clamping surface is concave along the direction vertical to the clamping board, and the other clamping surface is matched with the concave clamping surface in shape and is convex along the direction vertical to the clamping board. The stable brake adopts the convex clamping surface and the concave clamping surface that are matched, in the process from being contacted with the clamping board to being completely clamped and braked, the hoist rope is always restrained by the force applied by the concave arc clamping surface toward the center, thus avoiding the danger caused by the clamping board sliding from two sides, and compared with the traditional panel brake, the brake is more stable and safer.
Description
Technical field
The present invention relates to a kind of drg of elevator rope, particularly relate to a kind of parallel plate type drg of hoist ropes.
Background technology
The usual one end of hoist ropes is fixed on elevator counterweight, and the other end is fixed on car, is realized the lifting of elevator by forward and reverse rotation of traction sheave.Multi-rope friction hoisting form is a kind of form usually adopted, and has hoisting capacity large, the advantage that degree of safety is high.Usually the drg for hoist ropes used is the form of the two parallel plates folder rope braking adopted, because clamping surface is plane, and hoist ropes cross section is generally circular, when clamping piece applies pressure by clamping surface to hoist ropes sidewall, hoist ropes is easily to two Slideslips without any stop, hinder normal clamping, even hoist ropes skids off between two clamping pieces, affects elevator safety.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, provide a kind of structure simple, more stable, the stable type drg of the hoist ropes of energy available protecting elevator safety.
For achieving the above object, the technical solution used in the present invention is: a kind of stable type drg of elevator rope, described hoist ropes is two or more, longitudinal extension is parallel to each other and press straight-though arrangement, described drg comprises two pieces of clamping pieces be parallel to each other, and to be connected with clamping piece and to promote two clamping pieces engine installation close to each other, it is characterized in that: the opposite flank of described two clamping pieces is respectively clamping surface, one clamping surface edge is perpendicular to clamping piece direction indent, another clamping surface matches in shape with the clamping surface of described indent, edge is perpendicular to clamping piece direction evagination.
In a preferred embodiment of the present invention, the clamping surface comprising described indent further transversely diverse location has the arcwall face of identical indent.
In a preferred embodiment of the present invention, the lateral length comprising each clamping piece is further greater than the width of hoist ropes orientation entirety.
In a preferred embodiment of the present invention, the radius of curvature comprising the clamping surface cross-sectional plane circular arc of described indent is further 5-20 times of single hoist ropes diameter.
In a preferred embodiment of the present invention, comprising described engine installation is further cylinder.
The invention solves the defect existed in background technology, the stable type drg of elevator rope of the present invention adopts the machicolated form clamping surface cooperatively interacted, hoist ropes is from touching clamping piece to being clamped the process of braking completely, all the time the constrained force to center that imploded arcs shape clamping surface applies is subject to, and avoid the danger skidding off clamping piece from both sides, safety more more stable than traditional Flat plate type brake device.Arrange the radius of curvature of suitable indent clamping surface cross section circular arc, the length along hoist ropes orientation being conducive to clamping surface can well coordinate many hoist ropes width, and radian can give hoist ropes actv. constrained force simultaneously.

Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, 2, the stable type drg of a kind of elevator rope of the present invention, described hoist ropes 1 totally 5, longitudinal extension is parallel to each other and press straight-though arrangement, described drg comprises two pieces of clamping pieces be parallel to each other 2,4, and is connected with clamping piece 2,4 and promotes two clamping pieces engine installation close to each other.The opposite flank of described two clamping pieces is respectively clamping surface, and the clamping surface 21 of clamping piece 2 is along perpendicular to clamping piece 2 direction indent, and the clamping surface 41 of clamping piece 4 matches in shape with the clamping surface 21 of described indent, along perpendicular to clamping piece 4 direction evagination.The clamping surface 21 of described indent transversely diverse location has the arcwall face of identical indent.The radius of curvature of the clamping surface 21 cross-sectional plane circular arc of indent is 5-20 times of single hoist ropes 1 diameter.The lateral length of clamping piece 2,4 is all greater than the width of hoist ropes 1 orientation entirety.Engine installation described in the present embodiment is cylinder 6, is connected with clamping piece 4, can promote clamping piece 4 perpendicular to board plane direction near fixing clamping piece 2.Also other engine installations such as electromagnetism, motor can be adopted.
As shown in Figure 1, drg is fixed on a certain position on hoist ropes 1 sense of motion during installation, clamping piece 2,4 lays respectively at hoist ropes 1 both sides of straight-though arrangement, clamping surface 21,41 relative, the plane parallel that each hoist ropes 1 forms in two clamping pieces, clamping piece 2,4 be parallel to hoist ropes 1 bearing of trend.Adjustment drg horizontal position, makes the string of a musical instrument of clamping surface 21 cross-sectional plane circular arc, crossing with the longitudinal projection of both cross section circles of hoist ropes 1.So, ensure that hoist ropes 1 also can be subject to the stop protection of clamping piece 21 both lateral sides when normal operation.As shown in Figure 2, when starting to brake, it is vertical near clamping piece 2 that cylinder 6 promotes clamping piece 4, the intermediate ledge of clamping surface 41 divides contact hoist ropes 1 at first, then be more peripheral successively, outermost part, when horizontal outermost two hoist ropes 1 also contact with clamping surface 41, also space is left between clamping surface 21 and each hoist ropes 1, cylinder 6 promotes clamping piece 4 and continues mobile, clamping surface 41 whole hoist ropes 1 pushes clamping surface 21 to, hoist ropes 1 is subject to the constrained force that arc-shaped concave is gathered to centre, be firmly fixed between two clamping surfaces, realize braking, the hoist ropes 1 of both sides receives the two clamping pieces stops complementing each other to form closed retaining wall simultaneously, be difficult to outwards skid off, fool proof.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine technical scope according to right.
