In order to solve the problems of the technologies described above, the utility model provides adjustablely has a lower ballast longitudinal resistance checkout equipment of tiny fragments of stone, coal, etc. railway pillow, comprise and put reaction frame, underlying reaction frame, lifting jack, pressure transducer and displacement dial gauge, put on described and be equipped with the bolt chute consistent with the direction of transfer of the power of described lifting jack on reaction frame and the described underlying reaction frame, connect the described movable bolt of putting reaction frame and described underlying reaction frame at described underlying reaction frame with being connected to be equipped with in the bolt chute of putting reaction frame.
Being installed in the described lifting jack of putting on described between reaction frame and the described underlying reaction frame is fixed on and puts on the reaction frame on described.
Antetheca and the rear wall of putting reaction frame and described underlying reaction frame on described are rubbing surface, and described antetheca contacts with described pressure transducer, and described rear wall contacts with sleeper.
Described lifting jack is screw jack.
Adopt the adjustable of technique scheme to have tiny fragments of stone, coal, etc. railway to rest the head on lower ballast longitudinal resistance checkout equipment, under test Ballast track pillow before the ballast longitudinal resistance, first the fastener between removable sleeper to be detected and the two strands of rail is all unclamped, unload spring and nut and extract foot pad out, only stay the fastener screw spike.Successively reaction frame, screw jack, pressure transducer, displacement dial gauge are placed assigned address.Underlying reaction frame rear wall abutted in fixedly to be provided on the counter-force sleeper, utilizes movable bolt to regulate the position of putting reaction frame its rear wall is abutted on the sleeper to be detected.Utilizing fixedly, sleeper provides counter-force, afterburning by the screw jack of putting on being arranged between reaction frame and the underlying reaction frame, vertically pass sleeper to be detected, measure longitudinal thrust numerical value by pressure transducer, the displacement dial gauge measures sleeper length travel numerical value to be detected.Movable bolt on put reaction frame and be connected with the underlying reaction frame and connect, putting reaction frame and underlying reaction frame on guaranteeing can only be vertically relative movable, guarantees that power effectively do not disperse on correct direction of transfer.Screw jack is fixed on puts on the reaction frame, guarantees that power effectively do not disperse on correct direction of transfer; On put reaction frame and underlying reaction frame and antetheca and rear wall and be rubbing surface, guarantee afterburning before and reaction frame can be in the skew that vertically or laterally twists in the afterburner process, lifting jack is selected screw jack, the stable mechanical performance of screw jack.
The beneficial effects of the utility model are, the utility model equipment connects reaction frame by movable bolt, support between reaction frame constraint is provided, and the reaction frame front and rear wall made the increasing rubbing surface, guarantee that reaction frame can be in the skew that vertically or laterally twists before the reinforcing and in the afterburner process, so that longitudinal thrust is efficiently transmitted, can truly reflect ballast longitudinal resistance.In addition, the equipment longitudinal pitch is adjustable, and structure is succinct, and the reaction frame section optimal is lightweight, portable.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Such as Fig. 1, Fig. 2 and shown in Figure 3, equipment comprises puts reaction frame 2, underlying reaction frame 6, movable bolt 4, screw jack 3, pressure transducer 5 and displacement dial gauge 8, on put reaction frame 2 and hang up on removable sleeper 1 to be detected; Underlying reaction frame 6 hangs up fixedly to be provided on the counter-force sleeper 12, on put and be equipped with the bolt chute 13 consistent with the direction of transfer of the power of screw jack 3 on reaction frame 2 and the underlying reaction frame 6, in underlying reaction frame 6 and the bolt chute 13 of putting reaction frame 2 movable bolt 4 that reaction frame 2 and underlying reaction frame 6 are put in connection is installed, screw jack 3 is installed in to put between reaction frame 2 and the underlying reaction frame 6 and be fixed on and puts on the reaction frame 2; Pressure transducer 5 is arranged between screw jack 3 and the underlying reaction frame 6; Displacement dial gauge 8 arranges and acts on the sleeper embedded part 7.As shown in Figure 4, movable bolt 4 on put reaction frame 2 and be connected with the underlying reaction frame vertically and connect, putting reaction frame 2 on guaranteeing can only be in vertically relative activity with underlying reaction frame 6.On put reaction frame 2 and underlying reaction frame 6 antetheca 10 and rear wall 11 be rubbing surface, on put reaction frame 2 and underlying reaction frame 6 antetheca 10 contact with pressure transducer 5, on put reaction frame 2 and underlying reaction frame 6 rear wall 11 contact with sleeper.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the operating process of the present embodiment is: before the ballast longitudinal resistance of test sleeper, first the fastener between removable sleeper 1 to be detected and the two strands of rail 9 is all unclamped, unload spring and nut and extract foot pad out, only stay sleeper embedded part 7 screw spikes.Successively with on put reaction frame 2, underlying reaction frame 6, screw jack 3, pressure transducer 5 and displacement dial gauge 8 and place assigned address.The rear wall 11 of underlying reaction frame 6 abutted in fixedly to be provided on the counter-force sleeper 12, utilizing movable bolt 4 to regulate the position of putting reaction frame 2 abuts on the removable sleeper 1 to be detected its rear wall 11, then be installed in pressure transducer 5 on the screw jack 3 and be placed on and put between reaction frame 2 and the underlying reaction frame 6, displacement dial gauge 8 is installed on the sleeper embedded part 7.Adjust first the elongation of screw jack 3 before the test, so that screw jack 3, pressure transducer 5, on put reaction frame 2 and underlying reaction frame 6 is jointly stressed, and critical being squeezed on two sleeper surfaces, then the number of degrees with pressure transducer 5 and displacement dial gauge 8 return to zero.Test begins experiment after preparing all to finish.Because the fastener that fixedly provides on the counter-force sleeper 12 is not provided rail 9, therefore fixedly provide counter-force sleeper 12 itself not produce displacement.When making screw jack 3 afterburning, added power by pressure transducer 5 and on put reaction frame 2, underlying reaction frame 6 passes on the removable sleeper 1 to be detected.At this moment, be arranged in displacement dial gauge 8 pointers on the removable sleeper 1 to be detected along with removable sleeper 1 length travel to be detected, and measure the length travel value of sleeper.Record corresponding length travel value by applying different longitudinal forces, can obtain the longitudinal resistance test curve of railway roadbed under the Ballast track sleeper.
The utility model is applicable to ballast longitudinal resistance test newly-built and that runed common railway and high-speed railway Ballast track.
