Abstract
The utility model provides a self-discharging car rear-door automatic locking device, which comprises a locking mechanism, a lock tongue, a connection rod, a pressure device, a pressure device control valve, a touch block, a collision block and a door opening warning device. The locking mechanism is installed at the end on the bottom part of a carriage, the pressure device is fixed on the bottom part of the carriage, and the lock tongue is connected with the connection rod of the pressure device. The pressure device control valve is installed on a chassis of the car, and the top part of the pressure device control valve is provided with the touch block. When the carriage stays at the horizontal state, a spring jacks a pin in the locking mechanism to hold the rear door of the carriage, so that the rear door of the carriage is locked. When the carriage is hoisted, the pressure devices horizontally pushes the connection rod leftwards, and the lock tongue on the connection rod holds the pin in the locking mechanism so as to drive the pin to be separated from the rear door of the carriage, so that the rear door of the carriage is opened by the gravity itself or the gravity of materials. The device can effectively solve the problems of the prior art that the rear door of the self-discharging car cannot be tightly locked. The opening and the locking of the rear door of the carriage of the self-discharging car can be better controlled. The structure is safe and reliable.
Description
Technical field
The utility model relates to a kind of dumping car assembly, is specifically related to a kind of self dumping lorory back door jack automatic blocking device.
Background technology
The compartment of dumping car is usually used in transporting for example ore at present, dregs, and materials such as coal, its rear portion is provided with the back door usually.The back door is connected on the compartment by open-and-close mechanism.
But existing back door open-and-close mechanism generally is divided into elasticity open-and-close mechanism and rigidity open-and-close mechanism, and wherein the elasticity open-and-close mechanism is also referred to as the chain type open-and-close mechanism, and the rigidity open-and-close mechanism is also referred to as the rod-type open-and-close mechanism.Though these two kinds of open-and-close mechanisms are simple in structure, be easy to damage, also be easy under the unwitting situation of driver, open by mistake simultaneously, cause cargo leakage easily, cause environmental pollution and potential safety hazard.
The utility model content
The utility model is intended to avoid the above-mentioned weak point of background technology, provides a kind of carriage back door to close the automatic make and break device of self dumping lorory back door jack closely.
The purpose of this utility model provides a kind of self dumping lorory back door jack make and break device, can carry out actv. unlatching and closed, and structural safety is reliable.
The technical solution of the utility model is: a kind of self dumping lorory back door jack automatic blocking device.By locking mechanism, dead bolt, connecting rod, pressure apparatus, pressure apparatus control cock, contact block, compositions such as collision block and car door opening alarming device.Locking mechanism is installed in bottom end place, compartment, and locking mechanism is by lock box, and pin and spring constitute.Spring is positioned at lock box and is enclosed within on the pin that passes lock box.Described locking mechanism is with protective cover, the opening that its protective cover top has supply and marketing freely to come in and go out.Pressure apparatus is fixed in the bottom, compartment, and dead bolt is connected on the connecting rod of the pressure apparatus that is positioned at the bottom, compartment.The pin afterbody fluting place of matching in dead bolt and the locking mechanism is the inclined-plane.The pressure apparatus control cock is installed on the car chassis, and contact block is arranged at pressure apparatus control cock top.Described pressure apparatus can be hydraulic efficiency gear or is pneumatics.Described collision block and carriage back door are welded as a whole, and corresponding with the car door opening alarming device that is fixed in tail end bottom, compartment.
The utility model is simple in structure, is convenient to make, and it is reliable to operate steadily.
Description of drawings
Fig. 1. the utility model is when the body of tipper carriage lifting, and locking device is locked scheme drawing.
Fig. 2. when the utility model fell at body of tipper carriage, locking device was opened scheme drawing.
Among the figure: 1. locking mechanism; 2. dead bolt; 3. connecting rod; 4. pressure apparatus; 5. pressure apparatus control cock; 6. contact block; 7. collision block; 8. car door opening alarming device; 9. lock box; 10. pin; 11. spring; 12. protective cover; 13. carriage back door.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, shown in 2, in the utility model: a kind of self dumping lorory back door jack automatic blocking device.By locking mechanism 1, dead bolt 2, connecting rod 3, pressure apparatus 4, pressure apparatus control cock 5, contact block 6, compositions such as collision block 7 and car door opening alarming device 8.In order to guarantee that carriage back door 13 locks in transit, when discharging, discharge and open, we are installed in bottom end place, compartment with locking mechanism 1, and locking mechanism is by lock box 9, and pin 10 and spring 11 constitute.Spring 11 is positioned at lock box 9 and is enclosed within on the pin 10 that passes lock box 9.Described locking mechanism 1 all is with protective cover 12, and all there are supply and marketing 10 openings of freely coming in and going out on its protective cover 12 tops.Dead bolt 2 is connected on the connecting rod 3 of the pressure apparatus 4 that is positioned at the bottom, compartment.The pin 10 afterbodys fluting place of matching in dead bolt 2 and the locking mechanism 1 is the inclined-plane.Pressure apparatus control cock 5 is installed on the car chassis, and contact block 6 is arranged at pressure apparatus control cock 5 tops.Described pressure apparatus 4 can be hydraulic efficiency gear or is pneumatics.Described collision block 7 is welded as a whole with carriage back door 13, and corresponding with the car door opening alarming device 8 that is fixed in tail end bottom, compartment.
As shown in Figure 1, when compartment during by lifting, the compartment breaks away from contact block 6, at this moment pressure apparatus control cock 5 control presssure devices 4, make pressure apparatus 4 levels promote connecting rod 3 left, the pin 10 afterbodys fluting that connecting rod 3 drives in dead bolt 2 and the locking mechanism 1 fits, and pin 10 is vertically moved down, and spring 11 is tightened up to pin 10 break away from carriage back doors 13.Carriage back door 13 relies on self or material gravity to open.As shown in Figure 2, when the compartment falling is reset to horizontality, the compartment presses contact block 6, at this moment pressure apparatus control cock 5 control presssure devices 4, make pressure apparatus 4 levels spur connecting rod 3 to the right, the pin 10 afterbodys fluting that connecting rod 3 drives in dead bolt 2 and the locking mechanism 1 is separated, and spring 11 resets simultaneously, rely on the elastic force vertical direction of spring 11 self make progress roof pressure and lifting pin 10, make pin 10 block carriage back door 13.Make carriage back door 13 lockings.
