Abstract
The utility model discloses a towed machinery draw gear, and pertains to the machinery manufacturing technical field. The utility model consists of a drawing plate, a drawing rack and a main frame, wherein the drawing plate is fixed on the moveable drawing rack, one end of the drawing rack is connected with the main frame of a working machine via hinges, and the main frame is provided with an upward limiting beam and a moveable lock pin for the drawing rack. The utility model has the advantages of a simple and compact structure, scientific and reasonable connection form, convenient installation and maintenance, safe and reliable performance, and great convenience by only dismounting the moveable pins when used, and is very suitable for the traction of towed machinery.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, particularly relates to a kind of formula mechanical traction device technology of preparing of dragging.
Background technology
At present, the pull-alongs mechanical manipulator is divided into crawler type and rubber-tyred two big classes, all belongs to the self-propelled equipment of drive.But traction power and work mechanism power are independently power plant.During the work mechanism operation, often frame is propped with supporting leg.Existing known technology drags the formula drawbar frame stiff up and down, causes drawbar frame partly to meet with stresses, and wastes power and is awkward.
Summary of the invention
The utility model provides a kind of formula mechanical traction device that drags for solving the problem that existing known technology exists.
When this device moved when long distance, trac. dragged equipment by the towing plate that is welded on the movable drawbar frame.Movable drawbar frame is connected by hinge pin with one of equipment main car frame, and the other end is then fixed by spacing beam and removable pin locker, forms one, and the equipment center of gravity is between trailing wheel and towing point, but proper motion.When digging operation, dismounting activity lock, excavating machine makes a jack, and main car frame rises, and then movable drawbar frame can be around hinge pin to lower swing, and does not influence traction machine.Need pack up supporting leg in operation, when small distance moved, the tractor traction moving drawbar frame of taking over a job that is hooked together for guaranteeing safety, was plugged movable latch, made the vehicle frame formation one of movable drawbar frame and excacation device.This moment, hydraulic ram was packed up.Trac. can tow equipment.
During equipment work, at first movable latch is taken, make movable drawbar frame can around the swing hinge pin to lower swing, again hydraulic ram is propped downwards, this moment is relative to lower swing with the movable drawbar frame that trac. links to each other with the rising of rear portion equipment, but do not break away from traction, the driver can begin operation on the position of Background Job device.After finishing operation among a small circle, pack up hydraulic ram, but the trac. small distance directly tows the excacation device, and needn't plug movable latch, hold up Background Job device by support beam this moment, and operation is convenient and swift relatively.
The utility model adopts following technical scheme:
Drag formula mechanical traction device to be made of towing plate, drawbar frame, mainframe, be characterized in that towing plate is fixed in movable drawbar frame, drawbar frame one end and work mechanism mainframe link together by hinge pin, and mainframe has drawbar frame to upper limit beam and movable lock.
The utility model can also adopt following technical measures:
The above-mentioned formula mechanical traction device that drags is characterized in that movable drawbar frame one end is connected with the mainframe hinge pin, with the traction machine coupling end can be movable downwards.
Description of drawings
Fig. 1 is used for tractor traction excavating machine connection structure scheme drawing for the utility model.
Fig. 2 is draw gear and an excavating machine part birds-eye view among Fig. 1.
Fig. 3 is a connection structure scheme drawing of the present utility model.
Fig. 4 is the front elevation of Fig. 3.
Advantage that the utlity model has and good effect: this drags formula mechanical traction apparatus structure simple, compact, connection mode science, reasonable, and installation and maintenance are convenient, performance is safe and reliable, using only needs the dismounting removable pin, very convenient, is fit to very much drag formula mechanical traction to use.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following example now, and conjunction with figs. is described in detail as follows:
Embodiment
With reference to accompanying drawing 1 and accompanying drawing 2, the draw gear of tractor traction excavating machine, constitute by towing plate 1, drawbar frame 2, mainframe 5,1 welding of connection structure towing plate is movable drawbar frame 2, drawbar frame 2 one ends and excavating machine mainframe 5 link together by hinge pin 6, and mainframe 5 has drawbar frame 2 to upper limit beam 3 and movable lock 4.
The operation of this example:
The draw gear of tractor traction excavating machine, when trac. normally drags the traction excavating machine, or need in operation, pack up supporting leg, when small distance moves, the tractor traction hook drags traction 1, for guaranteeing safety, movable latch 4 is plugged, make movable drawbar frame 2 and excavating machine vehicle frame 5 form one, trac. can tow excavating machine.
During excavating machine work, at first movable latch 4 is taken, make movable drawbar frame 2 can around the swing hinge pin 6 to lower swing, again hydraulic ram is propped downwards, this moment is relative to lower swing with the movable drawbar frame 2 that trac. links to each other with the rising of rear portion equipment mainframe 4, but do not break away from traction, the driver can begin digging operation on the position of Background Job device.After finishing among a small circle digging operation, pack up hydraulic ram, but the trac. small distance directly tows the excacation device, and needn't plug movable latch, hold up Background Job devices by support beam 4 this moment, and operation is convenient and swift relatively.
Claims (2)
1. drag formula mechanical traction device to constitute by towing plate, drawbar frame, mainframe, it is characterized in that: towing plate is fixed in movable drawbar frame, drawbar frame one end and work mechanism mainframe link together by hinge pin, and mainframe has drawbar frame to upper limit beam and movable lock.
2. the formula mechanical traction device that drags according to claim 1 is characterized in that: movable drawbar frame one end is connected with the mainframe hinge pin, with the activity downwards of traction machine coupling end.
