The present invention has following advantage and effect with respect to prior art:
1, the present invention has pull bar, switching controls mechanism, it is arranged on the opening of guide groove one end, switching controls mechanism comprises switches clamp and extension board, switch clamp and the upper and lower correspondence of extension board formation roller groove is set, roller groove is connected with guide groove, pull bar one end is connected in switches on clamp, railway carriage is realized and is risen or decline by means of fork type elevator, in the time of railway carriage self-unloading, must enter roller groove by roller, when roller enters roller groove, railway carriage is in decline state, now, making to switch clamp by pull bar opens, the power system of fork type elevator starts, roller is deviate from from the opening of opening, rotate and realize self-unloading around the fork type elevator hinged place of opposite side, switching controls mechanism can not only realize the rising of railway carriage or the switching of decline and self-unloading, but also can be controlled at self-unloading simultaneously under propradation, realizing self-unloading must be at decline state, realize like this safe in operation, avoid misoperation to cause the generation of safety misadventure, it is flexible that the present invention also has work, safe and reliable, the advantage that work efficiency and cost performance are high.
2, in switching controls of the present invention mechanism, be provided with spring and tooth plate, offer perforation on extension board, tooth plate is protruding with teeth change, in the time that needs railway carriage rises, teeth change is connected in the perforation near bar portion, and upper stopper is closed, and roller can only slide in guide groove and realize and rising along roller groove; In the time of the self-unloading of needs railway carriage, described roller moves on the perforation near bar portion, and now, teeth change pressurized exits the perforation near bar portion, and pushing drawing rod just can make teeth change move forward in the perforation away from bar portion.Like this can be in the time that railway carriage rise, make pull bar be switched tooth and block and can not stir, only have in the time that teeth change is subject to roller roll extrusion to exit perforation, pull bar just can be stirred, and pushing drawing rod makes bar portion along rotating with extension board hinged place, makes stopper open practical function conversion.
3, the present invention is also provided with gangbar, and two switching controls mechanisms couple together by gangbar, and gangbar is connected on pull bar, can only need use like this action that a pull bar can realize two switching controls mechanisms synchronous.
4, railway carriage registration device of the present invention comprises kelly, control the control lever that fork type elevator starts power, elastic telescopic block tongue and for controlling the flexible block tongue trigger mechanism of elastic telescopic block tongue, control lever is connected with block tongue trigger mechanism, as long as stir like this dynamic start and the contraction of elastic telescopic block tongue that control lever can make fork type elevator simultaneously, guarantee work smooth and easy and when railway carriage is during in propradation, if when the power of fork type elevator loses suddenly, because elastic telescopic block tongue puts in while coordinating the support that the parallel four-bar structure of fork type elevator can make to run out of steam at fork type elevator in the hole clipping of kelly, still can be held on current height, be unlikely to drop, thereby raising safety, in the time that railway carriage is elevated to certain altitude, can prevent that railway carriage from dropping suddenly.
5, vehicle frame of the present invention is provided with propons, propons both sides are fixed with limited post, limited post overcoat has damping spring, damping spring two ends are connecting vehicle frame and propons respectively, between limited post top and vehicle frame, in a distance, can make like this height difference of propons following left wheel and self adaptation, effectively damping, under the road conditions of hilly and mountainous land, there is good comformability, also there is the function that prevents that propons from fractureing.Stop bit capital end and vehicle frame in damping spring have certain distance, can limit deflection angle, prevent the excessive deflection of propons.
6, the present invention has tailgate, biside plate, tailgate self-unloading auxiliary mechanism and tailgate switching mechanism, and tailgate and biside plate are turning, when railway carriage is in the time rising, pendulum hooks and departs from limited post, baffle plate stops retracing spring to pull pendulum to hook rotation, and now, hook finger ends catches on the notch of chute; When railway carriage is in the time declining, pendulum hook is limited by limited post, stops retracing spring to pull pendulum to hook and rotates, and now, hook finger ends catches on the notch of chute equally; Under above-mentioned two states, if two tailgate switching mechanisms are locked, tailgate is in the lock state;
When railway carriage is during in self-unloading, hook and rotate up because railway carriage rotates up band movable pendulum, because limited post is fixed on vehicle frame, pendulum hook is struck, and retracing spring stretches, and pendulum hook promotes the body of rod makes hook refer to upwards rotate around universal driving shaft, hook the notch that finger ends moves apart chute, notch is opened, and railway carriage self-unloading completes while reset, under the effect of retracing spring, pendulum hooks and resets, pendulum hooks and pulls the body of rod to make hook refer to rotate around universal driving shaft, and hook finger ends catches on the notch of chute, and notch is closed.
7, the present invention is provided with foot-operated piece, and chaufeur is had a rest pin can be placed on to foot-operated piece in the time of step on the accelerator not or braking above; In the time that transport trolley travels on downhill path, chaufeur can step down in pin above foot-operated piece, prevents from toppling over forward because seat crosses sliding.
8, the power of fork type elevator of the present invention is hydraulic efficiency pressure system, Hydraulic Pump in hydraulic efficiency pressure system is connected with driving engine with starter cup by input belt pulley, output belt pulley, belt, Hydraulic Pump power is directly provided by driving engine, therefore, without actuating device is additionally set, in the time that needs fork type elevator starts, the power that makes to export belt pulley by starter cup being compressed to belt passes to input belt pulley by belt and Hydraulic Pump on drive hydraulic system principle is realized work, and starter cup tensioning principle is identical with tension wheel.In the time of belt tension, Hydraulic Pump pressure accumulation; When starter cup is not when tightening belt, Hydraulic Pump pressurize or pressure release.
