Abstract
The utility model relates to a rope clasper for a spiral spring lever. An outer clasping clip (1) is hinged with an inner clasping clip (2) on the position of a pin column (A), and the inner clasping clip and a main shaft (6) are connected into the integration. The utility model is characterized in that a spring seat whose interior is provide with a spring (3) is connected to the main shaft by a pin shaft (D), and a triangular rod member (4) is arranged between the spring (3) and the outer clasping clip. The triangular rod member (4) is hinged with the outer clasping clip (1) and the spring (3) respectively by the pin shafts (B, C), and the other end of the rod member (4) is connected with an opening wheel (7). The main shaft (6) is connected with a hanging rod by a hinge form (5).
Description
The utility model relates to the single jaw coil spring lever disengagement type rope clamping device of using on a kind of passenger and freight cableway.
Coil spring lever disengagement type rope clamping device is the key equipment in the cableway transportation.Jaw is held steel rope tightly when departures, and the steel rope in the motion is taken people or goods exit out of and made long-distance transportation by rope clamping device; The rope clamping device jaw opens when entering the station, and breaks away from steel rope, and institute's cargo can slowly be moved in the station or stop.Existing this type of rope clamping device is to directly act on jaw by inside and outside armful of card by acting force of the spring, comes steel rope is clamped, and is unreasonable in the design, wants folding when entering the station once, during departures again folding once be unfavorable for the life-span of spring.
The coil spring lever disengagement type rope clamping device that the utility model provides, it can improve the working condition of spring, guarantees that Clamping force is constant, and realizes automatic compensation for the Clamping force decay that attenuates because of steel rope and the jaw wearing and tearing cause.
The purpose of this utility model can reach by following measure: embrace card and inner holding card outward by the hinged formation jaw of pin, inner holding card and main shaft are connected as a single entity, it is characterized in that innerspring spring perch is associated on the main shaft by bearing pin, spring and outside embrace between the card triangle rod member arranged.
The triangle rod member is hinged by bearing pin and outer armful of card and spring respectively, and the other end of rod member is connected with opens wheel.
Adopt the hinge form to connect between main shaft and suspension rod
Fig. 1 is according to the structure diagram of the coil spring lever disengagement type rope clamping device that the utility model proposes, and jaw is in opening among the figure.Fig. 2 is closed (clamping) state.
As shown in the figure, it is regular jaw that inner holding card (2) connects with main shaft (6), and the outer card (1) of embracing links to each other by pivot pin (A) with inner holding card, and spring (3) links to each other with main shaft by bearing pin (D) in spring perch, and can swing around the D axle; Triangle rod member (4) is hinged on outer embracing between card and the spring by bearing pin (B, C).
The working process of rope clamping device: under the pressure of unlatching wheel (7) guide rail in the station on the triangle rod member (4), with the B point is to rotate under the mind-set of garden, in case rod member is crossed dead point (being that C order BD point line) self-locking, the application force of spring acts on the outer card of embracing by the triangle rod member, the outer card of embracing rotates around the A axle, makes jaw hold steel rope tightly; After entering the station, jaw opens, unlatching wheel (7) on the rod member (4) is under the pressure of guide rail, with the B hinge-point is to rotate on the mind-set of garden, behind the line that the C hinge-point is ordered by B point and D, under the application force of spring, the outer card of embracing rotates around bearing pin A, the realization jaw is opened, and can keep the jaw maximum to magnify state.
When steel rope attenuates or jaw when wearing and tearing, the outer card of embracing will increase the angle of inwardly rotating around axle A, make the trend of exerting oneself of spring reduce, but the force line trend of C and D is blocked perpendicular to outer embracing owing to this moment, the actual distance that the CD force line is ordered to A increases, and is equivalent to lever ratio and increases, therefore, the Clamping force that acts on steel rope also increases, and can realize the automatic compensation of Clamping force within the specific limits.
Rope clamping device adopts hinge type (5) to hang with connecting of suspension rod, and jaw also is convenient to the dismounting of suspension rod and rope clamping device to the unfavorable moment of torsion that steel rope causes when having eliminated climbing.
The utility model compared with prior art has following advantage: simple in structure, and the clear and science of operation principle; Be easy to the processing and manufacturing convenient operating maintenance, flexible movements are accurate, take off and hang reliably; Because the leverage of the triangle rod member that adopts, so that required power greatly reduces when the unlatching of jaw and clamping, and can reduce the jaw opening/closing frequency of half, chucking power is constant; The spring duty is good, is in complete relaxed state at the opening lower spring, has greatly improved the service life of spring, elongates at steel cable to attenuate or the jaw wearing and tearing can obtain to a certain degree auto-compensation when causing the chucking power decay.
Claims (3)
1, a kind of coil spring lever disengagement type rope clamping device, embracing card (1) and inner holding card (2) outward locates hinged at pin (A), inner holding card and main shaft (6) are connected as a single entity, the spring perch that it is characterized in that built-in spring (3) is associated on the main shaft by bearing pin (D), spring (3) and outside embrace between the card triangle rod member (4) arranged.
2, rope clamping device according to claim 1 is characterized in that triangle rod member (4) is hinged by bearing pin (B, C) and outer armful of card (1) and spring (3) respectively, and the other end of rod member (4) is connected with opens wheel (7).
