In preferred embodiment of the present invention, comprise that further the head of said protrusion caves inward along protrusion direction.
In preferred embodiment of the present invention, comprise that further the same position that said each clamping piece is provided with along the two ends of groove arrangement direction with another clamping piece is provided with the connected structure of working in coordination.
In preferred embodiment of the present invention, comprise that further said protrusion is foam or rubber protrusion.
In preferred embodiment of the present invention, comprise that further said protrusion is embedded in the hold down groove of said clamping piece, the hold down groove interior shape matches with said protrusion afterbody profile.
In preferred embodiment of the present invention; Comprise that further said protrusion comprises the connecting portion and section width fixed part greater than connecting portion section width of section width less than the protrusion section width along the afterbody of protrusion direction, fixed part than connecting portion away from the head that protrudes.
In preferred embodiment of the present invention, comprise that further said groove cross section is a circular arc, the shape of corresponding protrusion matches with circular groove.
In preferred embodiment of the present invention, comprise that further said protrusion fixed part cross section is a circular arc, corresponding hold down groove interior shape matches with the circular arc fixed part.
The invention solves the defective that exists in the background technology, the drg of elevator rope of the present invention adopts the form of groove and protrusion cooperation screens, secure lock hoist ropes; To its braking; Can prevent effectively that hoist ropes from sliding between two parallel clamping pieces, friction face is bigger, improves safety.Can adopt the asbestos protrusion, the buffering when utilizing its elasticity enhancing to contact with hoist ropes is to reach flexible braking, the purpose of protection hoist ropes.Connected structure is set on two clamping pieces in addition also can further helps to aim at screens and locking screens.Can also asbestos protrusion be set to be inserted into the form on the clamping piece, convenient damaged the replacing prolongs drg service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Among the figure: 1, hoist ropes, 2, clamping piece, 21, groove, 22, spacing protrusion, 4, clamping piece, 41, protrusion, 411, head, 412, connecting portion, 413, fixed part, 42, limited impression.
The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the scheme drawing of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of drg of protecting elevator rope of the present invention, braking object hoist ropes 1 is 3, longitudinal extension is parallel to each other and press straight-though arrangement.Said drg comprises two clamping pieces parallel to each other 2,4 and clamping piece actuating device, and the face that two clamping pieces are relative is a clamping surface separately, the clamping surface smooth.The sidewall of clamping surface one side of said clamping piece 2 is provided with 3 lengthwise strip grooves 21; The sidewall of clamping surface one side of clamping piece 4 is provided with and said groove 21 lengthwise bar shaped one to one protrusion 41, and said each groove 21 bearing of trend are parallel and be parallel to said 41 the bearing of trend that respectively protrudes.Said groove 21 cross sections are circular arc, and the shape of corresponding protrusion 41 matches with circular groove 21.And the radius of curvature of groove 21 cross section circular arcs equals hoist ropes 1 section radius, helps hoist ropes 1 firmly is locked in the groove 21, better braking.Said protrusion 41 is foam or rubber protrusion, reduces the wearing and tearing to hoist ropes 1, flexible braking.Each protrudes 41 head 411 and caves inward along protrusion direction; Cup depth is the 1/10-1/8 of hoist ropes 1 section radius; When preventing that head 411 from just contacting hoist ropes 1; The arc surface of the arc surface of head 411 and hoist ropes 1 produces bad slip, causes hoist ropes 1 displacement, can't get into respective slot 21 and the influence braking.Said protrusion 41 is embedded in the hold down groove of said clamping piece 4, and the hold down groove interior shape matches with said protrusion 41 afterbody profiles.Said protrusion 41 comprises that along the afterbody of protrusion direction section width is the connecting portion 412 and the fixed part 413 of section width greater than connecting portion 412 sections width of vertical bar shape less than the cross section of protrusion 41 sections width, and fixed part 413 is than the head 411 of connecting portion 412 away from protrusion 41.Said each section width is the width along 41 orientations of 3 protrusions.Said fixed part 413 cross sections are circular arc, and corresponding hold down groove interior shape matches with circular arc fixed part 413, can help the protrusion 41 better be embedded with hold down groove in.Said clamping piece 2 is respectively equipped with the spacing protrusion 22 perpendicular to clamping surface along the two ends of groove 21 orientations; The respective ends of clamping piece 4 is respectively equipped with the limited impression 42 of corresponding cooperation, the accurate location and the locking position that utilize this kind connected structure to assist groove 21 and protrusion 41 to realize hoist ropes 1.Also can along the two ends of groove 21 orientations the limited impression perpendicular to clamping surface be set respectively at clamping piece 2, the respective ends of clamping piece 4 is respectively equipped with the spacing protrusion of corresponding cooperation.Perhaps, be respectively equipped with spacing protrusion and limited impression perpendicular to clamping surface at clamping piece 2 along the two ends of groove 21 orientations, the respective ends of clamping piece 4 is respectively equipped with the limited impression and the spacing protrusion of corresponding cooperation.
During use; This drg is parallel to hoist ropes 1 length direction setting by the length direction of each groove 21; It is corresponding with corresponding hoist ropes 1 position with protrusion 41 that each organizes corresponding groove 21; And hoist ropes 1 is at groove 21 and protrude between 41, and the cross section arc string of a musical instrument of groove 21 and corresponding hoist ropes 1 cross section circle intersect.Glancing impact starts the clamping piece actuating device, and two clamping pieces are to hoist ropes 1 direction relative motion; Groove 21 is contact hoist ropes 1 earlier, and along groove 21 orientations location, 41 extruding hoist ropes 1 are protruded in the back with it; Be expressed to protrusion 41 heads 411 deformation when big; Spacing protrusion 22 contacts with limited impression 42 and begins to peg graft, and prevents that hoist ropes 1 from skidding off groove 21 because of protruding 41 heads, 411 bigger bounces, assists the location.Last spacing protrusion 22 is plugged into the end with limited impression 42, and the clamping surface of two clamping pieces fits tightly, and hoist ropes firmly is locked in groove 21 and protrudes 41, and braking is accomplished.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification sheets, must confirm technical scope according to the claim scope.
