Abstract
The utility model relates to a fixture special for hanging a high speed steel rail, which comprises a fixture hanging beam, double-board hanger rods hinged with the fixture hanging beam, a fixture mechanism hinged with the double-board hanger rods, the fixture hanging beam is of a square box body structure, a hanging tendon board is arranged in the box body, three double-board hanger rods with the fixture mechanism are hinged on the tendon board of the box body in the stagger mode by a pin shaft on the hanging board, the fixture mechanism comprises a left pliers arm, a right pliers arm, a left pliers and a right pliers, the middle parts of the left pliers and the right pliers are hinged by the pliers pin shaft, a self-lock pin is arranged at the hinged joint position of the left pliers arm and the left pliers, one end of the connecting bar with the self-locking apparatus is hinged on the right pliers by the pliers arm pin shaft, the other end of the connecting bar with the self-locking apparatus is lapped on the self-lock pin. The utility model has advantages that three ultra-long heavy rails can be hung by one time, not only the working efficiency can be improved effectively, but also the rail hanging space length can be ensured to be not larger than 30 mm because of the stagger arrangement of the three fixture mechanisms, the utility model is convenient for machining and transporting.
Description
Technical field
The utility model belongs to the weight-lifting equipment technical field, relates in particular to a kind of lifting high speed rail unit clamp.
Background technology
Along with development and national economy, railway is also constantly progressive towards the high speed construction, in building, high ferro adopts 500 meters long high speed rail usually, generally when this high speed rail of lifting adopt group's lifting, it is single clamp mechanism that its group hangs on clamp mechanism, the structure of this clamp mechanism comprises the anchor clamps drop in beam, and with the two plate suspension rods of anchor clamps drop in beam pivotally attached, clamp mechanism is hinged with two plate suspension rods.Its weak point is to lift 500 meters long rail, inefficiency at every turn.
Summary of the invention
The purpose of this utility model provides and a kind ofly once can lift three one steel rails, the high speed rail unit clamp of high efficiency.
The purpose of this utility model realizes in the following manner:
High speed rail unit clamp of the present utility model, comprise the anchor clamps drop in beam, two plate suspension rods of anchor clamps drop in beam pivotally attached therewith, two therewith plate suspension rod pivotally attached clamp mechanisms, it is characterized in that described anchor clamps drop in beam is the square box structure, in casing, be provided with and hang gusset, three two plate suspension rods that have clamp mechanism are hinged on the gusset of casing by the boatswain chair upper pin is staggered, described clamp mechanism comprises by boatswain chair lower bearing pin and two plate suspension rod pivotally attached left clamp arms, right clamp arm, respectively by the tong arm bearing pin left clamp that is hinged of left clamp arm and right clamp arm therewith, right clamp, described left clamp, the middle part of right clamp is hinged by the clamp bearing pin, hinged place at left clamp arm and left clamp is provided with self-lock pin, connecting rod one end that has self-locking device is hinged on the right clamp by the tong arm bearing pin, and the other end is overlapped on the self-lock pin.
The utility model is compared with original technology has following advantage: owing to adopted above-mentioned unit clamp, when lifting super long heavy rail, once can lift three one steel rails, not only improved work efficiency effectively, and owing to three clamp mechanisms are crisscross arranged, can guarantee that the spacing that track hangs is not more than 30 millimeters, be convenient to processing and transportation, satisfied on-the-spot technological requirement.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the A-A cutaway view of the utility model Fig. 1.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As Fig. 1, shown in Figure 2, high speed rail unit clamp of the present utility model, comprise anchor clamps drop in beam 1, two plate suspension rods 4 of anchor clamps drop in beam 1 pivotally attached therewith, two therewith plate suspension rod 4 pivotally attached clamp mechanisms, it is characterized in that described anchor clamps drop in beam 1 is the square box structure, in casing, be provided with and hang gusset 2, three two plate suspension rods 4 that have clamp mechanism are by boatswain chair upper pin 3 staggered being hinged on the gusset 2 of casing, described clamp mechanism comprises by boatswain chair lower bearing pin 5 and two plate suspension rod 4 pivotally attached left clamp arms 6, right clamp arm 7, respectively by the tong arm bearing pin 9 left clamp 11 that is hinged of left clamp arm 6 and right clamp arm 7 therewith, right clamp 12, described left clamp 11, the middle part of right clamp 12 is hinged by clamp bearing pin 10, hinged place at left clamp arm 6 and left clamp 11 is provided with self-lock pin 14, connecting rod 8 one ends that have self-locking device 13 are hinged on the right clamp 12 by tong arm bearing pin 9, and the other end is overlapped on the self-lock pin 14.
When the lifting rail, the unit clamp that hoisting crane will lift rail is parked in the top of rail, make this unit clamp accurate in locating control, when unit clamp descended, the left clamp 11 on the clamp mechanism, right clamp 12 made left and right clamp keep open configuration by self-locking device like this; Behind clamp contact track, self-locking releasing guarantees that clamp clamps that rail is unlikely to fall; When the rail handling to assigned address and after putting down rail, auto-lock function is opened, and extracts clamp out, finishes next working cycle.
