Abstract
The utility model discloses a normally-closed rail clamping structure. The structure of a top entering part (2) is as follows: the end head of a piston rod of a top entering cylinder (5) is provided with a circular pull rod (7); a compression spring (6) is arranged between the circular pull rod (7) and the top entering cylinder (5); the top entering cylinder (5) of the top entering part (2) is fixed on a rack (1); two clamping claws (3) are arranged at the two sides of the top entering cylinder (5) by taking the axial center line of the top entering cylinder (5) as symmetry axis, and the upper ends of the two clamping claws (3) are respectively hinged with the rack (1); one ends of two connecting rods (4) are respectively hinged with the two clamping claws (3) and the other ends thereof are hinged with the circular pull rod (7) of the top entering part (2); and the top entering part (2) can lead the two clamping claws (3) to clamp the lower part of the upper edge of a rail under the pretightening force function of the compression spring (6). The utility model is the normally-closed rail clamping structure with convenient assembly, stability, reliability and flexible opening and closing.
Description
Technical field
The utility model relates to a kind of track clamp structure, particularly relates to a kind of normally closed track clamp structure.
Background technology
Rail clamping device is necessary the mechanism that guarantees the track engineering equipment safety operation, adopts track clamping mechanism grip track, thereby in equipment operation or the safety and stability of stage assurance equipment of resting.
Present harbour machinery equipment, a large amount of mechanical equipments such as subterranean tunnel winning equipment all adopt rail mounted to move.In the course of the work, load variations is big, and when the outside of the strong point, needs grip track; When equipment rests, make equipment occur moving or capsizing case, need grip track equally for avoiding the external force effect.The track clamping device becomes the essential mechanism on the rail mounted engineering equipment.
Present track clamping device adopts manual, electronic or single oil cylinder top to stretch the purpose that connecting rod reaches grip track more.Long or poor stability of the time that the single grip track needs is for the frequent engineering equipment that opens and closes of need and be not suitable for.
The utility model content
Technical problem to be solved in the utility model provides a kind of easy to assembly, and is reliable and stable, opens and closes normally closed track clamp structure flexibly.
In order to solve the problems of the technologies described above, the normally closed track clamp structure that the utility model provides, the structure that parts are stretched on the top is to push up the piston rod end of stretching oil cylinder to be provided with round pull bar, stretch on described round pull bar and described top and to be provided with compression spring between the oil cylinder, the top that parts are stretched on described top is stretched oil cylinder and is fixedly mounted on the frame, two jaws are stretched oil cylinder with described top and axially are symmetricly set on described top to stretch both sides and its upper end of oil cylinder hinged with described frame respectively, two connecting rods are hinged with two described jaws respectively with the one end respectively, it is hinged that the round pull bar of parts is stretched on the other end and described top, parts are stretched under the predetermincd tension effect of described compression spring in described top, can make the bottom of two described jaw grip track upper edges.
Described round pull bar is stretched the piston rod end of oil cylinder by being threaded with described top.
Adopt the normally closed track clamp structure of technique scheme, oil cylinder is stretched on the top of adopting the top to stretch mechanism and compression spring provides the top to stretch power, makes the jaw clamping or unclamps track by connecting rod.Grip track is that the predetermincd tension that the pressured spring that contracts provides guarantees that it is to stretch the hoisting force that oil cylinder provides by the top that jaw unclamps.The utility model has improved the reliability and the safety that clamp being not that normally closed is in the grip track state when the top is stretched oil cylinder and injected hydraulic oil, owing to adopt this structure, this utility model realizes the conversion that clamps, get loose easily, and reliable and stable.
In sum, the utility model is a kind of easy to assembly, reliable and stable, opens and closes track clamp structure flexibly.In production of track engineering implement and working process, can increase work efficiency, guarantee the stable normally closed track clamp structure of work safety
Description of drawings
Fig. 1 is the utility model grip track scheme drawing;
Fig. 2 is the utility model track scheme drawing that gets loose;
Fig. 3 is the assembling scheme drawing that parts are stretched on top of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2 and Fig. 3, the structure that parts 2 are stretched on the top is to push up the piston rod end of stretching oil cylinder 5 to be provided with round pull bar 7 by being threaded, stretch on circle pull bar 7 and top and to be provided with compression spring 6 between the oil cylinder 5, the top that parts 2 are stretched on the top is stretched oil cylinder 5 and is fixedly mounted on the frame 1, two jaws 3 are stretched oil cylinder 5 with the top and axially are symmetricly set on the top to stretch both sides and its upper end of oil cylinder 5 hinged with frame 1 respectively, two connecting rods 4 are hinged with two jaws 3 respectively with the one end respectively, the other end is hinged with the round pull bar 7 that parts 2 are stretched on the top, parts 2 are stretched under the predetermincd tension effect of compression spring 6 in the top, can make the bottom of the upper edge of two jaw 3 grip track 8.
Referring to Fig. 1 and Fig. 3, parts 2 are stretched under compression spring 6 predetermincd tension effects in the top, by connecting rod 4 is stretched on the top, make the bottom of the upper edge of jaw 3 grip track 8 downwards.Referring to Fig. 2 and Fig. 3, the top is stretched the top of parts 2 and is stretched oil cylinder 5 rod end chamber oil-feeds, by connecting rod 4 is upwards shunk, jaw 3 and track 8 is got loose.
Referring to Fig. 1, Fig. 2 and Fig. 3, adopt the normally closed track clamp structure of technique scheme, oil cylinder 5 is stretched on the top of adopting the top to stretch mechanism 2 and compression spring 6 provides the top to stretch power, makes jaw 3 clampings or unclamps track 8 by connecting rod 4.Grip track 8 is that the predetermincd tension that the pressured spring 6 that contracts provides guarantees that it is to stretch the hoisting force that oil cylinder 5 provides by the top that jaw 3 unclamps.Stretching the oil-feed of oil cylinder 5 rod end chambers and oil extraction by the top reaches the top and stretches the flexible control of parts.The utility model has improved the reliability and the safety that clamp being not that normally closed is in the grip track state when oil cylinder 5 injection hydraulic oil are stretched on the top.
In sum, this utility model realizes the conversion that clamps, get loose easily, and reliable and stable.
