Accompanying drawing explanation
Fig. 1 is the integral structure schematic diagram of container dump truck in the embodiment of the present invention;
Fig. 2 is the structural representation of embodiment of the present invention container dump truck hull automatic switch locking device.
Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the container dump truck of the present embodiment, dumping car is provided with ginseng the part compositions such as operator's compartment 1, vehicle frame 2, hull 3 for bearing container, hull jacking system 4, the hull lock 5 be arranged on hull 3.Wherein, hull 3 tail end and vehicle frame 2 are rotatably connected, and drive the front end of hull 3 tilt to rise or decline by hull jacking system 4.
In the present embodiment, described jacking system 4 can adopt the lift oil tank of HYDRAULIC CONTROL SYSTEM to realize the elevating control to hull 3.When adopting the dumping car shown in Fig. 1 to carry out the handling hauling operation of bulk goods, first hull 3 is set level, and the hull lock 5 hull 3 being used for fixed set vanning is adjusted to lockset position of coupler; Then utilize crane sling by the freight container that bulk goods is housed and be placed on hull 3, and hull is locked just be inserted in the lockhole that container base offers, complete entrucking process.
After dumping car bearing container is transported to target location, utilizes jacking system 4 to drive hull 3 to tilt to rise, to pour out the bulk goods in freight container, complete Discharging Process.Rise in the process of unloading at hull 3, in order to avoid freight container turns over from hull 3, need hull lock 5 to adjust to locked position of coupler, to fix freight container.
Shown in seeing figures.1.and.2, in order to realize the automatic switch control to hull lock 5, the present embodiment proposes a kind of hull lock recloser 6 of Purely mechanical, for being clear that the structure of hull lock recloser 6, only give hull in Fig. 2 and be in non-jacking condition, the local structural graph of itself and vehicle frame.In the present embodiment, hull lock recloser 6 mainly comprises ball head connecting rod 6-1, pull bar 6-2 and touching device; Touching device comprise the first touching body 6-3, the spring 6-4 that are rotatably connected on hull 3 and be fixed on to touch on vehicle frame 2, with first body 6-3 corresponding arrange second touch body 6-5, the upper surface of the second touching body 6-5 is the inclined-plane 6-6 that advances, and the bottom of the first touching body 6-3 is provided with can at the roller 6-7 that inclined-plane 6-6 rolls that advances; The two ends of pull bar 6-2 connect the top of the other end connection first touching body 6-3 of hull lock 5 and ball head connecting rod 6-1, ball head connecting rod 6-1, the top linking springs 6-4 of the first touching body 6-3 respectively; Drive ball head connecting rod 6-1 and first touching body 6-3 to move when hull 3 is elevated to desired location by spring 6-4, and then pull pull bar 6-2 to drive hull lock 5 to turn to lockset position of coupler or locked position of coupler.
Specifically, in the present embodiment, hull lock recloser 6 is two covers, is positioned at the left and right sides of hull 3.Ball head connecting rod 6-1 two ends, can free adjustment with bulb, as up and down, length adjustment etc., hull can be driven flexibly to lock 5 turn to lockset position of coupler or locked position of coupler by its cylinder lever connecting rod.
When hull 3 is in horizontality, roller 6-7 is positioned at the bottom of the inclined-plane 6-6 that advances, and the top of the first touching body 6-3 is that pulling force applies state to spring 6-4, makes spring 6-4 be in extended state.When jacking system 4 drives hull 3 to rise, roller 6-7 rolls obliquely along the inclined-plane 6-6 that advances, when hull 3 rises to desired location, roller 6-7 departs from the inclined-plane 6-6 that advances, originally the spring 6-4 being in extended state bounces back under its elastic deformation effect, thus pull the first touching body 6-3 and ball head connecting rod 6-1 to move, and then drive pull bar 6-2 to pull hull to lock 5 90-degree rotations, realize shutting; When jacking system 4 drives hull 3 to drop to desired location, roller 6-7 rolls obliquely along the inclined-plane 6-6 that advances, make the top extension spring 6-4 gradually of the first touching body 6-3, spring 6-4 pulls ball head connecting rod 6-1 thus drives pull bar 6-2 to pull hull to lock 5 and rotates, when to drop to the angle of vehicle frame 2 be zero to hull 3, hull lock 5 is back to unlocking condition.In the present embodiment hull 3 rise or decline desired location be extremely the angle of hull and vehicle frame 2 be 5 °, this angle can adjust according to concrete handling situations.
Described in the present embodiment, the first touching body 6-3 is U-shaped steel, and its U-shaped cavity is relative with the inclined-plane 6-6 that advances, and roller 6-7 is positioned at the bottom position place of this cavity.
The realization that first touching body 6-3 is rotatably connected, is arrange an axis hole in the middle, hull 3 is fixed with connecting link pin 7, to be connected to touch body 6-3 by first and be connected to rotationally on hull 3 by axis hole with connecting link pin 7.Certainly, other connection modes also can be adopted to realize, as by installation hinge or hinge etc., the present embodiment does not do concrete restriction to this.
Second touching body 6-5 is triangular in shape, for triangle touches iron, is welded on vehicle frame 2.
Pull bar 6-2 is the L-type metallic object in being inverted 90 ° to side, thus makes it form rocker structure, is convenient to rotate.
On the tail end of hull 3, the left and right sides all arranges pin shaft hole, on the left and right sides of vehicle frame 2, correspondence arranges pin shaft hole, the tail end of hull 3 is all connected to vehicle frame 2 by connecting link pin 8 through the pin shaft hole on hull 3 and vehicle frame 2 by the tail end left and right sides of hull 3 rotationally, and the double pin axle realizing hull 3 is fixed.So, hull 3 has jacking system bearing and is connected three, bearing pin place attachment point with the tail end left and right sides, and hull place plane obtains firm support, avoids the axially loaded connecting pivot pin, has both avoided hull wigwag motion, and in turn ensure that safety.
The above is only preferred embodiment of the present invention, and be not restriction the present invention being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solution of the present invention content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
