Compared with the prior art, the utility model, have following advantage and effect: the pendulum rod adopts two festival rod forms, and when lifting the train, after the prosthomere mine car touched the pendulum rod, the pendular movement was done to the pendulum rod, nevertheless because the movable joint in the middle of the pendulum rod avoids the dead point to appear, can not appear dying with the vehicle card, has improved inclined drifts transportation safety nature.
Description
Technical field
The utility model relates to a kind of nunchakus formula fork stop buffer.
Background technology
" safety regulations in coal mine " the 370th article requirement: use in gradient tunnel during tube-train hoisting and must install the buffer stop that the vehicle of outage rope, unhook can be stoped in gradient tunnel.Using more in buffer stop is fork stop buffer, fork stop buffer principle of work is as follows: the location that arrester 2 is arranged on below the grade change point of parking lot, top and the gradient is larger, as shown in Figure 1, under normal circumstances, arrester 2 is normally opens, during installation, fork 1 is rear, and arrester 2, front, leaves certain distance between fork 1 and arrester 2.Its radical function is that the vehicle of the company's of preventing extension continues down sport car and train and is in operation and occurs to break off relations or disconnected rope derailing accident.The speed impacts fork 1 that train normally runs, arrester 2 can not be caused to fall, once generation derailing accident, the mine car of fast downlink clashes into fork 1, and as shown in Figure 2, fork 1 is due to effect of inertia, shock mixes short wooden stake device, as shown in Figure 3, be arranged on and mix the shackle line ring sticked up and deviate from, arrester 2 falls immediately thus is tackled by mine car.Fork 1 stop buffer of current use generally adopts direct hanging type, there is very large defect: upper carry train time after prosthomere mine car touches fork 1, fork 1 does pendular movement and deutomerite vehicle has an opportunity to cause movement dead stuck, causes the bending even bogie truck off-road of fork 1; There is the phenomenon of stop buffer when speed of experiment is low.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, nunchakus formula fork stop buffer fork can being avoided to do pendular movement and deutomerite vehicle cause movement dead stuck.
The technical scheme in the invention for solving the above technical problem is:
A kind of nunchakus formula fork stop buffer, comprise swing link bracket, fork, mix short wooden stake device, arrester support and arrester, described short wooden stake device of mixing is fixed on swing link bracket, fork is hinged on swing link bracket, the upper end thereof of arrester is on arrester support, the other end of described arrester support connects one end of connection cord, the other end of described connection cord connects mixes short wooden stake device, it is characterized in that: described fork comprises upper pendulum bar, draft link, the upper end thereof of upper pendulum bar is on swing link bracket, and the upper end thereof of draft link is in the lower end of upper pendulum bar.
As preferably, described short wooden stake device of mixing comprises for producing the swing component of swing and the Connection Block for being connected connection cord by after pendulum impact, the other end of connection cord is provided with the junction button in round, junction button hangs on Connection Block, swing link bracket is provided with the pin that the other end for tissue-welding rope moves down, the middle part of described swing component is hinged on swing link bracket, and described Connection Block is fixed on the upper end of swing component, and the lower end of described swing component is positioned at the hunting range of fork.Adopt this mechanism, after swing component produces swing after being subject to pendulum impact, Connection Block is movable downwards, and the other end of connection cord is stopped by pin, thus realizes the other end of connection cord and the disengaging of Connection Block.
As preferably, connected by Flexible Connector between upper pendulum bar and draft link, described Flexible Connector comprises rubber strip, outer square tube and interior square tube, outer square tube offers the mounting hole for holding rubber strip and interior square tube, four interior angle places of mounting hole are respectively arranged with four columniform rubber strips, interior square tube is inserted in described mounting hole, and rubber strip is clamped between two inwalls of mounting hole and an outer wall of interior square tube, and outer square tube, interior square tube fix upper pendulum bar and draft link respectively.
As preferably, swing link bracket and arrester support adopt channel-section steel.
As preferably, also comprise pulley bracket, described pulley bracket is rotatablely equipped with pulley, described connection cord is overlapped on pulley.
The utility model compared with prior art, have the following advantages and effect: fork adopts nunchakus form, upper carry train time, after prosthomere mine car touches fork, fork does pendular movement, but because the movable joint in the middle of fork, avoids dead point to occur, there will not be with vehicle stuck, improve oblique lane transport safety; Fork stop buffer is integral installation, low to underground site field engineering level requirement; Arrester haulage cable is connected by movable lug with fork stop buffer, even hangs safe and reliable, and touching comes off easily; Connected by Flexible Connector between upper pendulum bar and draft link, to prevent in swing process relative angle between upper pendulum bar and draft link to diminish, thus avoid fork hunting range to diminish, ensure protection effect.
