Abstract
The utility model discloses a railway clamping device belonging to the technical field of railway conveying device. The railway clamping device comprises an electrohydraulic brake fixed on a supporting frame. The output shaft of the electrohydraulic brake is hinged with a pressure rod in the middle part of which a supporting point fixed to the supporting frame is provided, and the other end of the pressure rod is pushed against a spring upper supporting seat which is sheathed with a motion lever which is sheathed on the supporting frame. A spring lower supporting seat is arranged on the lower end of the motion rod, and a spring is arranged between the spring upper supporting seat and the spring lower supporting seat. Two upper connecting rods are symmetrically hinged on the lower side of the spring lower supporting seat, and two lower connecting rods are respectively hinged on the lower ends of the two upper connecting rods; the middle parts of the two lower connecting rods are hinged with the supporting frame, and the lower ends of the lower connecting rods are provided with a friction pair which is provided with opposite friction surfaces. The utility model can make the conveying device tightly fixed on the railway by friction force, and has the advantages of simple structure and convenience manufacture; the railway clamping device can be widely used on the conveying device provided with railway.
Description
Technical field
The utility model relates to a kind of anchor fitting of track load transfer device, particularly a kind of fixing device.
Background technology
In the prior art, multiple track load transfer device is arranged, be used to carry various materials, these load transfer devices have a common characteristic, promptly when shifting control position, can realize by orbital motion, when its normal operation, for preventing load transfer device along the track shift position, adopt way usually with the scroll wheel locking, realize the location by the rolling that limits roller, its weak point is: this locking device structure complexity, make difficulty, in addition, can not guarantee that roller does not slide in orbit.
The utility model content
The purpose of this utility model provides a kind of track fixing device, when making it be used on the track load transfer device, load transfer device reliably can be locked in orbit, and it is simple in structure, and is easily manufactured.
The purpose of this utility model is achieved in that a kind of track fixing device, comprise the electrohydraulic brake that is fixed on the support, be hinged with depression bar on the output shaft of electrohydraulic brake, the depression bar middle part is provided with the fulcrum that is fixed on the support, the other end of depression bar is conflicted on upper bracket of the spring, upper bracket of the spring is socketed on the shifting bar, shifting bar is socketed on the support, the shifting bar lower end is provided with spring lower support, be provided with spring between upper bracket of the spring and the spring lower support, spring lower support downside symmetry is hinged with two boxed rods, the boxed rod lower end is hinged with lower link respectively, the middle part of two lower links is hinged on the support, and the lower end of lower link is provided with the friction pair that friction face is provided with in opposite directions.
Electrohydraulic brake is a kind of device commonly used in the prior art, when it is switched on, and hydraulic ram work, the promotion output shaft stretches out or withdraws; When the utility model uses, support is fixed on the load transfer device of track top, and make two friction pairs lay respectively at the track both sides, when output shaft stretches out, promote depression bar and rotate around fulcrum, the other end compression spring of depression bar also drives shifting bar and moves downward, shifting bar drives the hinged place of intermediate connecting rod and lower link and outwards stretches, and then order about the friction pair that is fixed on the lower link and inwardly move, friction pair touches track, can rely on friction force that feedway is tightly fixing in orbit.The utility model is simple in structure, and is easily manufactured, can be widely used on the load transfer device that has track.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
Wherein, 1 electrohydraulic brake, 2 depression bars, 3 fulcrums, 4 shifting bars, 5 upper bracket of the spring, 6 springs, 7 spring lower supports, 8 supports, 9 boxed rods, 10 lower links, 11 friction pairs.
The specific embodiment
As figure, a kind of track fixing device, comprise electrohydraulic brake 1, electrohydraulic brake 1 is fixed on the support 8, be hinged with depression bar 2 on the output shaft of electrohydraulic brake, depression bar 2 middle parts are provided with the fulcrum 3 that is fixed on the support, the other end of depression bar 2 is conflicted on upper bracket of the spring 5, upper bracket of the spring 5 is socketed on the shifting bar 4, shifting bar 4 is socketed on the support 8, shifting bar 4 lower ends are provided with spring lower support 7, be provided with spring 6 between upper bracket of the spring 5 and the spring lower support 7, spring lower support 7 downside symmetries are hinged with two boxed rods 9, and boxed rod 9 lower ends are hinged with lower link 10 respectively, the middle part of two lower links 10 is hinged on the support 8, and the lower end of lower link 10 is provided with the friction pair 11 that friction face is provided with in opposite directions.
When the utility model uses, support 8 is fixed on the load transfer device of track top, and make two friction pairs 11 lay respectively at the track both sides, when electrohydraulic brake 1 energising, output shaft stretches out, promoting depression bar 2 rotates around fulcrum, the other end compression spring 6 of depression bar 2 also drives shifting bar 4 and moves downward, shifting bar 4 drives intermediate connecting rod 9 and outwards stretches with the hinged place of lower link 10, and then order about the friction pair 11 that is fixed on the lower link 10 and inwardly move, friction pair 11 touches track and compresses with track, can rely on friction force that feedway is tightly fixing in orbit.When electrohydraulic brake 1 outage, friction pair and track break away from naturally, and load transfer device can be free to slide along track.
