Description
Technical field
The utility model belongs to truck unloading system of circular type tipper technical field, relates in particular to the safe stop buffer of unloading system of circular type tipper.For after transfer platform leaves, block because of car puller link up with the vehicle unsuccessfully causing slip transfer platform machine cheat in accident.
Background technology
Tipper unloading system is a kind of high-efficient automatic operating system that steel mill, power plant, harbour etc. are located that is widely used in, for dumping truck.In the tipper unloading system of layout of turning back, in order to prevent that vehicle from falling into transfer platform machine hole in the time that transfer platform leaves, after tipper, before transfer platform, establish safety backstop apparatus, all safety backstop apparatus all adopt the version of blocking wheel of vehicle at present.When actual use, car puller with tipper in when coupling of vehicles, as can not be the company of completing hung, empty wagons will be gone out tipper by high-speed impact, the safety backstop apparatus of taking turns of now keeping off a car cannot block vehicle because position is too low, easily occurs that empty wagons falls into the industrial accident in transfer platform hole, and therefore existing unloading system of circular type tipper all just starts action after transfer platform returns, unload and have the wait time of car puller in the cycle, cause the cycle of unloading of whole Zigzag type unloading system long, efficiency is low.
Therefore develop a kind of safe stop buffer that can eliminate car puller wait time in the process of unloading and become technical barrier urgently to be resolved hurrily.
Summary of the invention
The purpose of this utility model is the safe stop buffer of a kind of unloading system of circular type tipper of exploitation, can block empty wagons and prevent that it from falling in transfer platform hole, eliminates car puller wait time in the process of unloading.
The purpose of this utility model is achieved through the following technical solutions: the safe stop buffer of unloading system of circular type tipper, comprise push rod device and the linkage of keeping off a car, push rod device comprises the transfer bar mechanism being arranged on basis, ground and is arranged on the band inclined guide plate of transfer platform termination, transfer bar mechanism comprises the push rod case that is fixed on ground, be contained in push rod spring and push rod in push rod case, the front portion of push rod is provided with baffle plate, push rod is through push rod case, push rod spring is sleeved on push rod, push rod spring is between the anterior baffle plate of push rod and push rod case end face, stretch out outside push rod case end face the rear and front end of push rod, push rod front end elevates above the soil outside basis, be positioned at position, termination, transfer platform machine hole, push rod front end is provided with pulley, the band inclined guide plate that be equipped with described transfer platform termination is that two ends are inclined-planes, middle part is the guide plate of plane, it is characterized in that, the described linkage of keeping off a car comprises the fork of keeping off a car, rocking arm, crank arm and rocker shaft, the described fork of keeping off a car is Y type member, the end of two bifurcateds of Y type member is hinged on basis, ground by hinge, two hinge-points are positioned at the both sides of push rod device, the vertical portion of Y type member has chute, and chute is strip shape open-work, described rocker shaft is d-axis, and rocker shaft is by bearings on basis, ground, and the center of rocker shaft length direction is corresponding with the rear end of the push rod of push rod device, the rear end of the push rod of described push rod device is provided with push rod shaft, and described rocking arm is two, and the leading section of two rocking arms is slidably connected at the both sides of the chute of the fork of keeping off a car by rocking arm head shaft, and the rearward end of two rocking arms is fixedly connected on the both ends of rocker shaft, the front aperture of described crank arm is slotted hole, crank arm rear end is fixed on rocker shaft, be that crank arm and rocker shaft and two rocking arms are slidably connected at by rocking arm head shaft on the chute of the fork of keeping off a car, the push rod shaft sliding block joint of crank arm front end slotted hole and putting back-end.
The safe stop buffer of unloading system of circular type tipper described in the utility model, is characterized in that; Described chute length of keeping off a car on fork is in the time that rocking arm head shaft moves to runner rear end, and the fork of keeping off a car falls into ground rail track bottom, and in the time that rocking arm head shaft moves to chute front end, the fork of keeping off a car is raised to truck hitch with high position.
The safe stop buffer of unloading system of circular type tipper described in the utility model, is characterized in that; The safe stop buffer of described unloading system of circular type tipper, is characterized in that; The top of the described fork of keeping off a car is provided with shock absorber.
Principle of work of the present utility model is:
In the time that transfer platform is traversing, the band inclined guide plate that is contained in its termination promotes push rod and retreats, push rod rotates by the push rod shaft throw crank arm of its head, crank arm drives rocker shaft to rotate, and rocker shaft drives rocking arm to rotate, in the time that rocking arm head shaft moves in chute with the rotation of rocking arm, the drive fork of keeping off a car rotates around hinge, in the time that rocking arm head shaft moves to runner rear end, crank arm, rocking arm and the fork of keeping off a car fall under ground rail track, and open-top car can pass through transfer platform.
In the time that transfer platform leaves, under the effect of push rod spring, push rod moves forward along the inclined-plane of transfer platform termination band inclined guide plate, and the push rod shaft of push rod head drives crank arm to rotate, crank arm drives rocker shaft to rotate; rocker shaft drives rocking arm to rotate, and in the time that rocking arm head shaft moves in chute with the rotation of rocking arm, drives the fork of keeping off a car to rotate around hinge; the fork that makes to keep off a car progressively lifts; in the time that rocking arm head shaft falls into slideway front end terminal, lift end, in the position of keeping off a car.
When truck clashes into while keeping off a car fork, because rocking arm head shaft is in slideway terminal, can not produce movement, therefore can hold by the rocking arm fork of keeping off a car, the fork that makes to keep off a car blocks open-top car.
The safe stop buffer of the present utility model position of keeping off a car is moved highly to hitch, promotes rocking arm rotate by push rod, and the drive fork of keeping off a car rises and falls, the fork of the keeping off a car hitch place of position at vehicle of keeping off a car.Thereby the operating efficiency that promotes circular type tipper system, has ensured the safe reliability of keeping off a car.
Compared with prior art, the utlity model has following beneficial effect:
1, the position of keeping off a car is moved and high behind hitch position, has been improved the safe reliability of unloading, and avoids empty wagons to enter hole accident.
2, eliminate wait time, shortened the cycle of unloading, can improve whole unloading system efficiency approximately 10%.
3, both can be used for, in domestic and international various new unloading system of circular type tipper, also can be used for the transformation to existing circular type tipper.
