Description
Technical field:
The utility model relates to a kind of flat truck that is used for and connects carriage self adaptation arrangement for adjusting height.This device is to be used for flat truck in the large-scale factory, and the height adjustment of draw rod positions is guaranteed draw bar and the accurately contraposition of tie rod hole on the flat truck carriage in the tractor truck back seat, the failure-free connection.
Background technology:
The handle that drags of the traction seat of tractor truck and flat truck must ability successful connection in the effective travel scope.The draw bar on the tractor truck and the position of back seat are fixed, and accurately are connected with the flat truck tie rod hole in order to guarantee the back seat on the tractor truck, and the height that must guarantee the flat truck top rod could effectively successful connection in the contraposition effective travel scope of tractor truck back seat.During former producer design in order to save cost, the height adjuster of the draw rod positions of flat truck is to adopt one-level to turn to rigid connection, as shown in Figure 5, the heavier about 150KG of carriage 12 self, it is connected the height of carriage 12 top rod positions with bogie truck 14 by adapter shaft 13, as shown in Figure 5, realize by the bolt on the former setting device 15,, can't realize connecting if do not have this device carriage 12 because deadweight is landed.Former setting device is to be welded on the both sides channel-section steel of bogie truck 14 connecting portions by a pressing plate, it be by be welded on the bottom of adjustable bolt on the pressing plate withstand with carriage 12 and bogie truck 14 on channel-section steel, utilize the own wt of bogie truck 14, carriage 12 is upwards lifted.Though satisfied the connection height of draw bar on the carriage 12, there is defective in former factory this covering device of design-calculated in the practical application.The one, rigid connection, the bottom of easily causing adjustable bolt contacts the collision wearing and tearing firmly with the channel-section steel surface because ground-surface jolts, and causes the draw rod positions on the carriage to move down, and connects inconvenience; The 2nd, owing to be rigid connection, after running into the not gentle ramp of road, particularly the bottom of the former adjustable bolt of descending and channel-section steel connecting portion do not have activity space, and carriage 12 top rods are easily fractureed in the tractor truck back seat.
The utility model content:
The purpose of this utility model provides a kind of flat truck that is used for and connects carriage self adaptation arrangement for adjusting height.Solve vehicle that the easily loosening and rigid connection of existing height adjuster bolt exists and run into technical matters than the steep ramp frangibility.
The technical solution of the utility model is: a kind of flat truck that is used for connects carriage self adaptation arrangement for adjusting height, comprise carrier base, steel bushing, bearing pin, top board, lower platen and spring plate, carrier base is fixed in the fixing channel-section steel in carriage bottom surface, carrier base has the rotatable steel bushing of hollow cylinder, the built-in bearing pin of steel bushing, end face is fixed with screw by the bearing pin pressing plate, top board is welded on the steel bushing, lower platen and top board have groove, spring plate is installed in top board and presses down in the board slot, and at top board and lower platen used for drilling and tapping bolt of rear end plate with top board, lower platen and spring plate are connected and fixed.Be fixed with preceding stop block at carriage bottom surface channel-section steel and spring plate front end correspondence position, be fixed with the height adjustable bolt at bogie truck bottom surface channel-section steel and spring plate rear end correspondence position.
The beneficial effects of the utility model are: effectively be connected with pull bar on the carriage in order to ensure the back seat of tractor truck.Must guarantee on the carriage drawbar height with the back seat bonded assembly effective travel scope of tractor truck in, could successful connection.This device is welded on the channel-section steel of carriage, has formed an integral body with carriage.Because bearing pin is fixed by the bearing pin pressing plate, steel bushing and top board welding and lower platen with spring plate owing to being connected of bolt of rear end plate melt as a whole can the rotation, utilize the own wt of bogie truck to hold up carriage by lever principle, preceding stop block is welded on the channel-section steel of carriage, avoids the anterior Long contact time of spring plate to damage the channel-section steel structure; The height adjustable bolt contacts with the rear portion of spring plate, and bolt can come the height of the draw rod positions on the bracket by the left and right rotation that is welded on the nut on the bogie truck.Spring plate utilizes elasticity and toughness and the intensity thereof of self, the connecting portion activity that makes carriage and bogie truck freely, increase upper and lower action radius, particularly run into big ramp, can automatically restore to original height and position after the distortion of short time, the also not yielding and damage of spring plate can be used for a long time, avoids pull bar to be fractureed.
