Description
Technical field
The utility model relates to a kind of backhoe loader, is specifically related to a kind of rail clamping device of backhoe loader.
Background technology
Backhoe loader is used extensively in mining, but at present general rail wheel type backhoe loader does not have rail clamping device or manual type rail clamping device when parking mode of operation, has the defects such as the unreliable and operation inconvenience of work.
Utility model content
The purpose of this utility model is to provide a kind of rail clamping device that makes backhoe loader when work, itself and track reliably be combined as a whole.
This backhoe loader rail clamping device that the utility model provides, comprises intermediate rocker and symmetrical left and right two the rail tongsrail clamp assemblies that are connected in its two ends, and the length direction midpoint of intermediate rocker is connected with hoist cylinder; Rail tongsrail clamp assembly comprise folder cylinder of rail, folder rail crank arm and press from both sides rail link span, two folder rails are cranked arm and are arranged symmetrically with, their upper end respectively with folder cylinder of rail rod end and cylinder body end is hinged, lower end is connected with respectively clamp; The two ends of intermediate rocker are fixedly connected with the upper end of folder rail link span respectively, and the middle part that folder rail is cranked arm is hinged with folder rail link span respectively, and the upper end of folder rail link span and the inner of hoist cylinder are connected with rail formula walking chassis.
Described folder rail link span comprises cant board, lower connecting plate and upper link span, lower connecting plate is connected with cant board is vertical, upper link span comprises upper flat plate and is connected in two vertical clamping plate of its downside, the upper end of cant board is articulated with between two vertical clamping plate, the two ends of lower connecting plate are hinged with the middle part that described folder rail is cranked arm respectively, and the two ends of described intermediate rocker are fixedly connected with the upper end of cant board respectively.
Two clamps of described rail tongsrail clamp assembly and corresponding folder rail are hinged by bearing pin between cranking arm, spring cotter is spacing, one of them clamp with press from both sides rail crank arm between for being fixedly connected with, another can rotate around bearing pin.
Described folder rail crank arm and clamping oil cylinder between, between vertical clamping plate and cant board, logical bearing pin is hinged, spring cotter is spacing.
Backhoe loader, when walking states, is controlled rail tongsrail clamp assembly and is unclamped track and lift, and during parking operation, controls rail tongsrail clamp assembly and drops to grip track after control position.Specific works principle is as follows: when backhoe loader is during in parking operation, first by controlling hoist cylinder, rail tongsrail clamp assembly is down to control position, then the piston rod of controlling two folder cylinder of rail stretches out simultaneously, promoting folder rail cranks arm and is rotated down around the connecting pin axle between itself and lower connecting plate, make to press from both sides rail and crank arm the clamp of lower end near track, when the clamp of this side is fitted track, piston rod can not stretch out again, the cylinder body end of now pressing from both sides cylinder of rail drives the folder rail of opposite side to crank arm and is rotated down around the connecting pin axle between itself and lower connecting plate, the clamp that makes its lower end near track until laminating, now make to press from both sides cylinder of rail and stop action, complete reliable parking.When backhoe loader need to be walked, reverse operating.
The utility model adopts the mechanism of hydraulic-driven, the interlock of two rail tongsrail clamp, and the rail tongsrail clamp assembly being arranged symmetrically with by two covers is simultaneously by two railway clampings, the potential safety hazard while having avoided backhoe loader parking operation.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of backhoe loader rail clamping device that the utility model provides, comprises intermediate rocker 2 and symmetrical left and right two the rail tongsrail clamp assemblies 1 that are connected in its two ends, and the length direction midpoint of intermediate rocker 2 is connected with hoist cylinder 3.Rail tongsrail clamp assembly 1 comprises that folder cylinder of rail 11, folder rail crank arm 12 and folder rail link span 13.Two folder rails are cranked arm and 12 are arranged symmetrically with, and their upper end is respectively with the rod end of folder cylinder of rail 11 with cylinder body end is hinged, lower end is connected with respectively clamp 14.Folder rail link span 13 comprises cant board 131, lower connecting plate 132 and by upper flat plate 133 be connected in the upper link span that two vertical clamping plate 134 of its downside form, lower connecting plate 132 is connected with cant board 131 is vertical, the upper end of cant board 131 is articulated with between two vertical clamping plate 134, the two ends of lower connecting plate 132 are hinged with crank arm 12 middle part of folder rail respectively, and the two ends of intermediate rocker 2 are fixedly connected with the upper end of cant board 131 respectively; The inner of the upper end of upper flat plate 133 and hoist cylinder 3 is connected with rail formula walking chassis respectively.
That two clamps 14 of rail tongsrail clamp assembly 1 and corresponding folder rail are cranked arm is hinged by bearing pin between 12, spring cotter is spacing, and one of them clamp 14 is cranked arm between 12 as being fixedly connected with pressing from both sides rail, and another can rotate around bearing pin.
Folder rail crank arm 12 with clamping oil cylinder 11 between, between vertical clamping plate 134 and cant board 131, lead to that bearing pin is hinged, spring cotter is spacing.
Backhoe loader, when walking states, is controlled rail tongsrail clamp assembly 1 and is unclamped track and lift, and during parking operation, controls rail tongsrail clamp assembly 1 and drops to grip track after control position.Specific works principle is as follows: when backhoe loader is during in parking operation, first by controlling hoist cylinder 3, rail tongsrail clamp assembly 1 is dropped to control position, then the piston rod of controlling two folder cylinder of rail 11 stretches out simultaneously, promoting folder rail cranks arm and 12 around the connecting pin axle between itself and lower connecting plate 132, is rotated down, make to press from both sides rail and crank arm the clamp 14 of 12 lower ends near track, when the clamp 14 of this side is fitted track, piston rod can not stretch out again, the cylinder body end of now pressing from both sides cylinder of rail 11 drives the folder rail of opposite side to crank arm and 12 around the connecting pin axle between itself and lower connecting plate 132, is rotated down, the clamp 14 that makes its lower end near track until laminating, now make to press from both sides cylinder of rail 11 and stop action, complete reliable parking.When backhoe loader need to be walked, reverse operating.
The utility model adopts the mechanism of hydraulic-driven, the interlock of two rail tongsrail clamp, and the rail tongsrail clamp assembly being arranged symmetrically with by two covers is simultaneously by two railway clampings, the potential safety hazard while having avoided backhoe loader parking operation.
