The self-locking rail clamping device is simple in structure and easy in production and can guarantee that the rail clamping device is firmly clamped on a rail and can not be disengaged under unexpected conditions, such as power outage and the like.
Description
Technical field
The present invention relates to weight-lifting equipment technical field, relate in particular a kind of self-locking rail clamping device.
Background technology
Patent announcement number discloses jaw iron and rail clamping device for self-locking rail clamping device for the Chinese utility model patent of CN202575729U, the day for announcing: 2012-12-05, rail clamping device comprises holder arms with jaw iron, described holder arms is fixed with chuck, described chuck is provided with clamp portion, described clamp portion is provided with a peristome that holds holdfast, in described clamp portion, be also provided with for upper grip head and lower pliers head with clamping phase interlock, described peristome is connected with upper grip head, lower pliers head respectively.The peristome arranging on chuck at the utility model is for holding track entity, upper and lower binding clip transmits next power and the interlock of track phase by holder arms, therefore track is difficult to throw off between upper and lower binding clip, and is not vulnerable to upper and lower binding clip and track because of the long-time problem that causes the not enough and then disengagement of friction force of using.But it also has weak point, it also can throw off with track under the situations such as accident power-off.
Summary of the invention
The object of this invention is to provide for the deficiencies in the prior art part, a kind of self-locking rail clamping device is provided, can overcome the deficiencies in the prior art part, it is simple in structure, easy to manufacture, can guarantee under the unforeseen circumstancess such as power-off, rail clamping device is firmly clamped in orbit, can not throw off.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: self-locking rail clamping device, comprise base, be hinged on a pair of retractor device that there is the clamping clip of chuck and drive described a pair of clamping clip to rotate on described base, on described base, be fixed with in orienting sleeve, described orienting sleeve and be provided with pilot bar, described pilot bar upper end is fixed with barrier ring, bottom is provided with clamp nut, described barrier ring is hinged by a pair of link rod and described clamping clip, is set with the Compress Spring between described barrier ring and described orienting sleeve on described pilot bar.
As preferably, described retractor device is cylinder.
As preferably, described retractor device is oil cylinder.
As preferably, described orienting sleeve comprises guide ring and is fixed on two side plates of described guide ring below.
As preferably, described a pair of link rod one end is hinged by two upper jointed shafts and described a pair of clamping clip, and the other end is hinged by lower jointed shaft and described barrier ring, and described lower jointed shaft is positioned at the belows of described two upper jointed shafts.
As preferably, described a pair of link rod one end is hinged by two upper jointed shafts and described a pair of clamping clip, and the other end is hinged by lower jointed shaft and described barrier ring, and described lower jointed shaft is positioned at the belows of described two upper jointed shafts.
Beneficial effect of the present invention is:
Simple in structure, easy to manufacture, can guarantee under the unforeseen circumstancess such as power-off, rail clamping device is firmly clamped in orbit, can not throw off.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
The following stated is only preferred embodiment of the present invention, not scope of the present invention is limited.
Embodiment, see accompanying drawing 1, self-locking rail clamping device, comprise base 1, be hinged on a pair of retractor device 3 that there is the clamping clip 2 of chuck 201 and drive described a pair of clamping clip 2 to rotate on described base 1, chuck 201 is provided with circular arc jaws, retractor device drives a pair of clamping clip 2 synchronously to rotate, realize the clamping of 201 couples of I-beam section guide rail a of chuck or unclamp, described retractor device 3 is cylinder or oil cylinder, two clamping clips are hinged respectively for cylinder body and piston rod, on described base 1, be fixed with orienting sleeve 4, in described orienting sleeve 4, be provided with pilot bar 5, described pilot bar 5 upper ends are fixed with barrier ring 6, bottom is provided with clamp nut 10, described barrier ring 6 is hinged by a pair of link rod 7 and described clamping clip 2, on described pilot bar 5, be set with the Compress Spring 8 between described barrier ring 6 and described orienting sleeve 4, clamp nut 10 can prevent that pilot bar 5 is pulled out under Compress Spring 8 spring-force driven duals, also be convenient to change Compress Spring simultaneously, when a pair of clamping clip clamps I-beam section guide rail, Compress Spring is compressed, and after power-off, the power of cylinder or oil cylinder disappears, and the spring force of Compress Spring makes a pair of link rod 7 drive clamping clip 2 outwards to rotate, and realizes the clamping to I-beam section guide rail.
Described orienting sleeve 4 comprises guide ring and is fixed on two side plates of described guide ring below, described a pair of link rod 7 one end are hinged by two upper jointed shafts 11 and described a pair of clamping clip 2, the other end is hinged by lower jointed shaft 9 and described barrier ring 6, and described lower jointed shaft 9 is positioned at the below of described two upper jointed shafts 11, described a pair of link rod 7 one end are hinged by two upper jointed shafts 11 and described a pair of clamping clip 2, the other end is hinged by lower jointed shaft 9 and described barrier ring 6, and described lower jointed shaft 9 is positioned at the below of described two upper jointed shafts 11, simultaneously, upper jointed shaft 9 is positioned at the below of retractor device 3 and a pair of clamping clip hinge-point.
