Abstract
The invention discloses an electric rail clamping device of a throw-off carriage. The electric rail clamping device comprises a rail clamping device support arranged on one side of the throw-off carriage, wherein rail clamping tongs and an electric hydraulic pushing rod pushing device which are in power connection are installed on the rail clamping device support, a large connecting rod is hinged between the top of the rail clamping device support and a pushing rod on the top of the electric hydraulic pushing rod pushing device, an upper connecting rod and a main supporting rod are sequentially hinged below the large connecting rod, and the outer wall of the main supporting rod is sleeved with a spring. The rail clamping tongs comprise two sets of lower connecting rods which are hinged to the bottom end of the main supporting rod at the same time, and two sets of clamping blocks which are 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 clamping device, the electric hydraulic pushing rod pushing device is utilized as a power source, on the basis of the lever principle, the lifting force is transmitted to the rail clamping tongs, clamping of the rail is achieved, the safety and reliability are high, in addition, due to the fact that the rail clamping tongs are only provided with one positioning shaft, the position of the positioning shaft can be floated according to the position of the rail, on the premise that the straightness error of the rail is large, the clamping action can be reliably completed, and the applicability is high.
Description
Technical field
The present invention relates to a kind of rail clamping device, be 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.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of compact conformation, easy to adjust, the reliable electronic rail clamping device of dummy car are provided.
An electronic rail clamping device, 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 present invention 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 invention (during grip track).
Fig. 2 is structural representation of the present invention (while unclamping track).
Fig. 3 is the structural representation of clamp in the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for the present invention is described but not for limiting the scope of the invention.
Embodiment 1
Referring to Fig. 1, the electronic rail clamping device of a kind of dummy car provided by the invention, 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.
Embodiment 2
Working process of the present invention 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.
Embodiment 3
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.
