Abstract
The utility model discloses an electric rail clamp for a throw-off carriage. The electric rail clamp comprises a rail clamp bracket arranged on one side of the throw-off carriage; rail tongs and an electric hydraulic pushrod pusher are installed on the rail clamp bracket, and the rail tongs are in power connection with the electric hydraulic pushrod pusher; a big connecting rod is hinged to the position, between the top of the rail clamp bracket and the top of the electric hydraulic pushrod pusher, of a pushrod; an upper connecting rod and a main jackstay are sequentially hinged to the lower portion of the big connecting rod; the outer wall of the main jackstay is sleeved with a spring; the rail tongs comprise two sets of lower connecting rods hinged to the bottom end of the main jackstay; two set of clamping blocks used for clamping a rail are symmetrically hinged to the bottom ends of the two sets of lower connecting rods. According to the electric rail clamp for the throw-off carriage, the electric hydraulic pushrod pusher is used as a power source, on the basis of the lever principle, lifting force is transferred to the rail tongs, so that the rail is clamped, and safe reliability is high. In addition, due to the fact that the rail tongs are only provided with a positioning shaft, the position of the rail tongs can float according to the position of the rail. In this way, under the condition that the straightness errors of the rail are large, a clamping action can still be reliably completed, and therefore adaptability is high.
Description
Technical field
The utility model relates to a kind of rail clamping device, is specifically related to the electronic rail clamping device of a kind of dummy car.
Background technology
Belt tripper is a kind of equipment that can at a point continuous discharge.Because the service direction component producing in material lifting process is for making dummy car slide to service direction, for guarantee to make it reliably locate and complete discharging work under severe duty, on general dummy car, all dispose drg, often there is in actual applications the situation that drg braking rear wheel does not roll and but slides in orbit, have a strong impact on the normal operation of equipment, and may jeopardize the safety of the person and equipment.
So it is necessary to increase rail clamping device on dummy car, though improve the rail clamping device there is manual pattern in sector application, can not meet the requirement that system is controlled automatically, on the dummy car being in operation operation also very inconvenient, and there is certain danger.And common electric or hydraulic rail clamp exist that structure is numerous and diverse, Reliability of Microprocessor is poor, defect that can not the actual supporting needs of fine adaptation dummy car.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of compact conformation, easy to adjust, the reliable electronic rail clamping device of dummy car are provided.
The electronic rail clamping device of dummy car, comprises the rail clamping device support that is arranged on dummy car one side, and rail tongsrail clamp and electric drive hydraulic thruster pusher that power joins are installed on described rail clamping device support; Described rail clamping device props up between top of the trellis and the push rod at electric drive hydraulic thruster pusher top and is hinged with big connecting rod, described big connecting rod below is hinged with connecting rod and main supporting rod successively, on the outer wall of main supporting rod, be arranged with spring, described rail tongsrail clamp comprises two groups of lower links that are simultaneously hinged on main supporting rod bottom, and described two groups of lower link bottom symmetries are hinged with two groups for the clamp of grip track.
As the further improvement of technique scheme,
Between described spring and main supporting rod, be provided with orienting sleeve.
As the further improvement of technique scheme,
Described spring bottom is provided with the setting nut being set on main supporting rod.
As the further improvement of technique scheme,
Described clamp is in being provided with wear-resistant pad with the face that touches of track.
The utility model is simple in structure, easy to use, utilize the electric drive hydraulic thruster pusher source that is used as power, by lever principle, will play power is delivered on rail tongsrail clamp, the clamping of realization to track, safe reliability is high, in addition because rail tongsrail clamp only has a fix shaft, can float according to the position of track in its position, in the situation that track straightness error is larger, also can reliably complete and clamp action, applicability is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (during grip track).
Fig. 2 is structural representation of the present utility model (while unclamping track).
Fig. 3 is the structural representation of clamp in the utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for the utility model is described but not for limiting scope of the present utility model.
Embodiment 1
Referring to Fig. 1, the electronic rail clamping device of a kind of dummy car that the utility model provides, comprise the rail clamping device support 1 that is arranged on dummy car one side, rail tongsrail clamp 2 and electric drive hydraulic thruster pusher 3 that power joins are installed on described rail clamping device support 1, between the push rod 4 at described rail clamping device support 1 top and electric drive hydraulic thruster pusher 3 tops, be hinged with big connecting rod 5, described big connecting rod 5 belows are hinged with connecting rod 6 and main supporting rod 7 successively, on the outer wall of main supporting rod 7, be arranged with spring 8, described rail tongsrail clamp 2 comprises two groups of lower links 9 that are simultaneously hinged on main supporting rod 7 bottoms, described two groups of lower links, 9 bottom symmetries are hinged with two groups for the clamp 11 of grip track 10.
Working process of the present utility model is: during 1 energising of electric drive hydraulic thruster pusher, its push rod 4 is released, and by connecting rod mechanism, thrust is delivered on main supporting rod 7, makes to move on described main supporting rod 7, and rail tongsrail clamp 2 completes and unclamps action (as shown in Figure 2); Otherwise when push rod 4 is regained, main supporting rod 7 promotes lower link 9 under the effect of spring 8 pre-compression forces, thereby make described clamp 11 lower end grip track 10.
As the further improvement to embodiment 1, between described spring 8 and main supporting rod 7, be provided with orienting sleeve 12, object is to prevent to be out of shape after spring 8 pressurizeds.
Embodiment 4
As the further improvement to embodiment 1, described spring 8 bottoms are provided with the setting nut 13 being set on main supporting rod 7, and object is to utilize setting nut 13 can change the precompressed compression stroke of spring 8, thereby regulate gripping power.
Embodiment 5
As the further improvement to embodiment 1, referring to Fig. 3, described clamp 11 is in being provided with wear-resistant pad 14 with the face that touches of track 10.Object is to improve the service life of clamp 11, and the clamping degree of raising and track 10.
