Abstract
The utility model discloses a floating-type rail clamping device, which comprises a connecting frame (3), a connecting shaft (4), a clamp block (5) and a supporting wheel component (9), wherein one end of the clamp block (5) is articulated with the connecting frame (3) by the connecting shaft (4); the connecting frame (3) is fixed at one end of a host machine (2); and the upper end of the supporting wheel component (9) is fixedly connected with the clamp block (5). The floating-type rail clamping device can reliably adapt to the rail with greater high-low and left-right deviation.
Description
Technical field
The utility model relates to a kind of rail clamping device, particularly a kind of floating type rail clamping device.
Background technology
The rail clamping device of existing rail mounted lifting operation machinery (can abbreviate " main frame " as) windproof usefulness adopts clamp-type mostly, its principle of work is and the effect of main frame bonded assembly rail clamping device by spring force or gravity process connecting rod mechanism etc., make clamp tightly clamp rail, prevent that main frame from being blown away by strong wind; During the main frame walking, clamp is unclamped by hydraulic efficiency pressure system.The caliper unit of existing rail clamping device is fixed on the frame, frame is connected with main frame with link span by adapter shaft, the bogie wheel that is fixed on the frame contacts with track, track adjusting wheel is then unsettled to be fixed on the adapter shaft, when track just differed big, jaw was raised and be can't clip track or track adjusting wheel chokes track downwards and causes damage; In addition because itself the rock when nonstraightness of rail and host work, the track adjusting wheel quick abrasion, the gap between rail clamping device jaw and rail is very big, and excessive clearance, the clamp forced stroke is too big, causes mechanism very huge again.The described rail clamping device of Chinese patent ZL200720066328.9 has overcome aforesaid shortcoming preferably, but because its distance between independently about caliper unit and the clamp seat is also little, when track just differs big, the clamp seat can hold up whole caliper unit, thereby make the jaw position raising and can't clip track, even whole caliper unit skids off track, the caliper unit walking shakiness if the distance between about caliper unit and the clamp seat strengthens.And in the used track of current track formula lifting operation machinery, the phenomenon that track just differs bigger is very general, has restricted the use of rail clamping device.
The utility model content
The technical problems to be solved in the utility model is in order to overcome the defective of prior art, a kind of floating type rail clamping device is provided, it has been avoided by the centering directional tagging because the jaw wearing and tearing that main frame double swerve and track directly do not cause, and can adapt to and just to differ bigger track.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of floating type rail clamping device, it is characterized in that, it comprises link span, adapter shaft, clamp seat and support roller assembly, one end of clamp seat is hinged and connected by adapter shaft and link span, link span is fixed on an end of a main frame, captives joint with the clamp seat in the upper end of support roller assembly.
Preferably, described floating type rail clamping device also comprises a caliper unit of being made of one wheel, clamp, clamp axle, jaw, body frame, connecting rod, spring, oil cylinder, clamp is connected with wheel by the clamp axle, the two ends of connecting rod, the two ends of oil cylinder all are connected with clamp, spring is connected with connecting rod, the other end of clamp seat is supported on the surface of body frame by the support roller assembly, and jaw is clamped a track.
Preferably, described clamp seat is provided with a hollow out, and caliper unit is positioned over this hollow out place.
Preferably, the quantity of described wheel is two, and the support roller assembly is between two wheels.
Positive progressive effect of the present utility model is: the floating type rail clamping device of the utility model can both adapt to reliably to height, track that left-right deviation is bigger.

The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the floating type rail clamping device of the utility model comprises link span 3, adapter shaft 4, clamp seat 5, support roller assembly 9 and caliper unit, and an end of clamp seat 5 is hinged and connected by adapter shaft 4 and link span 3, and link span 3 is fixed on an end of main frame 2.The other end of clamp seat 5 is supported on the surface of body frame 6 by support roller assembly 9, captives joint with clamp seat 5 in the upper end of support roller assembly 9.As shown in Figure 2, the clamp seat 5 that steel plate is welded cuts out the hollow out greater than caliper unit geometrical projection shape in the middle of its base plate, because link span 3 is fixed on an end of main frame 2, power is delivered to clamp seat 5 by adapter shaft 4.As shown in Figure 3, caliper unit is formed and is positioned over the hollow out center of clamp seat 5 by wheel 10, clamp 8, clamp axle 7, jaw 14, body frame 6, connecting rod 12, spring 11, oil cylinder 13, caliper unit is supported on the track 1 by wheel 10, the quantity of wheel 10 is two, clamp 8 is connected with wheel 10 by clamp axle 7, the two ends of the two ends of connecting rod 12, oil cylinder 13 all are connected with clamp 8, and spring 11 is connected with connecting rod 12.Caliper unit is not captiveed joint with clamp seat 5, and left and right directions leaves big gap, and the gap between the fore-and-aft direction is then less.When main frame 2 outages quit work, the hydraulic efficiency pressure system off-load, spring 11 acts on the clamp 8 by connecting rod 12, makes jaw 14 tightly clamp track 1.When strong wind promotion main frame 2, clamp seat 5 is collided with caliper unit, so just makes main frame 2 be blocked and do not blown away by strong wind by caliper unit.When main frame 2 energising was started working, hydraulic efficiency pressure system overcame the spring force of spring 11 to oil cylinder 13 fuel feeding, and clamp 8 is opened together with jaw 14, and main frame 2 just can drive rail clamping device and walks together like this.During walking, when main frame 2 double swerves or track not straight, because wheel 10 is less with the gap of track 1 side, caliper unit can touch track 1 all the time, and clamp seat 5 plays the centering directional tagging by support roller assembly 9 in body frame 6 surperficial sway, guaranteed the gap of jaw 14, avoided the jaw wear damage with rail 1.
As shown in Figure 4 and Figure 5, when track is uneven, main frame 2 raises or reduction with the end that link span 3 drives clamp seat 5, the other end of clamp seat 5 is supported on body frame 6 surfaces by support roller assembly 9, because support roller assembly 9 is between two wheels 10, thereby make the wheel 10 of caliper unit can be close to orbital plane and unlikely tumbling.How Tube vice seat 5 does not move up and down like this, and caliper unit can be close to orbital plane and unlikely tumbling all the time, has guaranteed the correct applying situation of jaw and track.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only are casehistorys, under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
