Abstract
The utility model discloses a clamping rail device which comprises a box body (1), wherein a hydraulic cylinder (2) is arranged above the box body (1), the two ends of the hydraulic cylinder (2) are respectively connected with clamping arms (3) for clamping guide rails, the hydraulic cylinder (2) and the clamping arms (3) can form a clamp mechanism. The clamping rail device further consists of a guide mechanism which comprises rolling bearings (4) and a bracket (5), wherein the bracket (5) is arranged on the bottom of the box body (1), and the rolling bearing (4) are arranged on the lower portion of the bracket (5), and are arranged on the two sides of the guide rails in parallel. The clamping rail device has simple structure, can guarantee a moving device to be fixed on a required work position reliably and stably, and can assure the moving device to walk without barriers.
Description
Technical field
The utility model relates to a kind of anchor fitting, relate in particular to a kind of be used for fixing the movable equipment that can move on the guide rail embrace the rail device.
Background technology
In the modern mechanical commercial production, the equipment that has needs multistation to operate, and needs frequent mechanically moving body satisfying job requirement, as being used for the driving of lifting, carrying under the environment in the open; The shear gauge that is used for the cutting steel of mill etc.These equipment all are mounted on the fixing track, can move freely in orbit, and can be fixed on any position that needs stop.These equipment of moving are realized by corresponding traveling gear, can finish by embracing the rail device and fix these equipment.
The rail device of embracing in the prior art only has clamping mechanism, and actual conditions are, movable equipment tends in the process of walking because there is certain deviation in guide rail, the clamping limb and the guide rail interference of rail device may occur embracing, and walking has some setbacks; In addition, when movable equipment need be fixed on a certain control position, because the error that guide rail exists can make that the clamping driving surface and the guide rail of clamp arm are asymmetric, this moment, clamping mechanism was difficult to realize good, firm clamping.
The utility model content
The technical problems to be solved in the utility model provides a kind of energy and realizes that accessible walking clamp effective armful rail device simultaneously.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of armful of rail device, comprise casing, above casing, be provided with hydraulic actuating cylinder, two ends at hydraulic actuating cylinder are connected with the clamp arm that is used to clamp guide rail respectively, above-mentioned hydraulic actuating cylinder and clamp arm form clamping mechanism, and this armful rail device also comprises guiding mechanism, and described guiding mechanism comprises antifriction-bearing box and support, its medium-height trestle is located at the bottom of casing, and antifriction-bearing box is located at the bottom of support and is located at the guide rail both sides side by side.
Be provided with major axis in described casing, be rotatably connected to floating shelf on major axis, the lower end of floating shelf and two clamp arms flexibly connect, thereby form the unsteady self-regulation mechanism of embracing the rail device.
Compared with prior art, the utility model technology has the following advantages:
1, the utility model can guarantee the accessible walking of movable equipment.The utility model is by being provided with the guiding mechanism of being made up of antifriction-bearing box and support on armful rail device; therefore; when deviation appears in guide rail, the clamp arm that guiding mechanism can be protected the clamping mechanism in the walking not with guide rail interference, the traveling that movable equipment just can be fluent.
2, the utility model clamps effective.In the prior art, when movable equipment need owing to may there be guiding error, cause two clamp arms and guide rail asymmetric, can influence the clamping effect after certain station stops.The utility model is by being provided with floating shelf, when two clamping surfaces of clamp arm and guide rail are asymmetric, can cause the fulcrum of the junction of floating shelf and main shaft to be subjected to force unbalance, under this state, fulcrum can move to state of equilibrium voluntarily, in this course, the mobile position of two clamp arms of having regulated of floating shelf fulcrum with respect to guide rail, make that two clamp arms can be that line of centers is symmetrically distributed with the guide rail, when clamp arm clamps like this, clamping surface can well contact with guide rail, thereby has guaranteed reliable, stable being fixed on the station that needs of movable equipment.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the front view that the utility model is embraced the rail device.
Fig. 2 is the left view of shown in Figure 1 armful of rail device.
The specific embodiment
See figures.1.and.2, a kind of armful of rail device, comprise casing 1, above casing 1, be provided with hydraulic actuating cylinder 2, be connected with the clamp arm 3 that is used to clamp guide rail respectively at the two ends of hydraulic actuating cylinder 2, above-mentioned hydraulic actuating cylinder 2 forms clamping mechanism with clamp arm 3, this armful rail device also comprises guiding mechanism, described guiding mechanism comprises antifriction-bearing box 4 and support 5, its medium-height trestle 5 is located at the bottom of casing 1, antifriction-bearing box 4 is located at the bottom of support 5 and is located at the guide rail both sides side by side, and the quantity of antifriction-bearing box 4 has four in the present embodiment, is divided into the both sides that two row are located at guide rail side by side, in described casing 1, be provided with major axis 6, be rotatably connected to floating shelf 7 on major axis 6, the lower end of floating shelf 7 and two clamp arms 3 flexibly connect, thereby form the unsteady self-regulation mechanism of embracing the rail device.
Owing to set up guiding mechanism and unsteady self-regulation mechanism in the utility model, therefore, not only can guarantee the accessible walking of movable equipment, can in time adjust the driving surface of clamp arm simultaneously, guarantee that two driving surfaces are symmetrically distributed in the both sides of guide rail, guaranteed the effect that clamps.
When the utility model is installed, need guarantee the utility model and movable equipment synchronous walking with casing by being bolted on the movable equipment.The utility model when moving to the station that needs, drives hydraulic actuating cylinder in the course of the work, hydraulic actuating cylinder is opened, and the action of two clamp arms clamps guide rail, has realized fixing movable equipment, in addition, the user can determine needs concrete quantity of the present utility model according to the actual conditions of movable equipment.
Claims (2)
