Abstract
The utility model relates to a structure for connecting a traction pin plate and supports with a frame. The structure is characterized in that traction pin strengthening longitudinal beams and front and back beams are arranged on the traction pin plate; connecting supports are arranged on the junctions of the traction pin strengthening longitudinal beams and the front and back beams. During use, as to the connection of the traction pin plate and the supports with the frame, the connection on both the vertical plane and the horizontal plane are realized, thus the connection parts are enabled to have enough torsional strength despite of up-down jumping or front-back playing of left and right girders; a bolt-on connection structure is mainly adopted between the parts, thereby being more suitable for the mass-production and long-distance assembly production mode, welding defects are not generated, and the replacing is convenient even if the parts are damaged; the limit pin structure is also adopted, thereby preventing the connecting bolt from bearing too large shear force.
Description
Technical field
The utility model relates to the technical field of superimposed trailer, specifically a kind of for drawing the draw bail between pin plate and support and vehicle frame.
Background technology
For a long time, due to the stressed complexity in semi-trailer traction pin place, between the traction pin plate of superimposed trailer and support and semi-trailer frame, be generally welded structure.But along with economic fast development, this welded structure is unfavorable for manufacturing enterprise's modularization, mass production superimposed trailer, also cannot form the novel production model of parts batch machining, strange land assembling.
And the welded structure between traction pin plate and support and vehicle frame easily produces weld defect in the time of welding, causes this stressed complex region weld cracking of semi-trailer traction pin plate and support, once welded structure generation part damages, also cannot keep in repair by quick-replaceable.
Summary of the invention
The purpose of this utility model is to provide the draw bail between a kind of improved traction pin plate and support and vehicle frame, it can overcome draw bail in prior art is welded structure, and non-fabricated structure cannot dismounting, once weld cracking in use procedure, cannot quick-replaceable the some shortcomings of maintenance.
To achieve these goals, the technical solution of the utility model is: a kind of draw bail of drawing between pin plate and support and vehicle frame, for traction pin plate is fixed on to semitrailer crossbeam, it is characterized in that: traction pin plate is provided with towing pin and strengthens longeron and front and back crossbeam, and the junction that towing pin is strengthened longeron and front and back crossbeam is provided with connecting rack.
When use, the connection that connects existing vertical plane of traction pin plate and support and vehicle frame, there is again the connection of horizontal surface, guarantee no matter be left and right crossbeam bob or front and back vibration, point of attachment all has enough torsional strengths, the main structure that adopts Bolt Connection between parts, be more suitable for the production model of batch manufacturing, strange land assembling than welded structure, and can not produce weld defect, even if parts damage and are also convenient for changing, also adopt locating dowel pin structure can prevent that attachment bolt from bearing excessive shearing force.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the draw bail schematic diagram of the utility model semitrailer crossbeam and crossbeam connecting rack.
Fig. 3 is the another draw bail schematic diagram of the utility model semitrailer crossbeam and crossbeam connecting rack.
Fig. 4 is the draw bail schematic diagram of the utility model traction pin plate and front and back crossbeam.
Detailed description of the invention:
Below in conjunction with drawings and Examples, the utility model will be further described.
Label in each accompanying drawing is expressed as follows: 1 traction pin plate, 2 towing pins are strengthened longeron, 3 front and back crossbeams, 4 connecting racks, 5 semitrailer crossbeams, 6 towing pin crossbeams, 7 crossbeam connecting racks, 8 locating dowel pins.
Described a kind of draw bail of drawing between pin plate and support and vehicle frame, for traction pin plate is fixed on to semitrailer crossbeam, it is characterized in that: traction pin plate is provided with towing pin and strengthens longeron and front and back crossbeam, and the junction that towing pin is strengthened longeron and front and back crossbeam is provided with connecting rack.Towing pin is strengthened longeron and is had two, is set up in parallel on traction pin plate, and two towing pins are strengthened being provided with towing pin crossbeam between longeron, and towing pin crossbeam and towing pin reinforcement longeron are vertically intersected on the medium position of towing pin reinforcement longeron.The connection that connects existing vertical plane of traction pin plate and support and vehicle frame, has again the connection of horizontal surface, guarantees that point of attachment all has enough torsional strengths regardless of being left and right crossbeam bob or front and back vibration.
The front/rear end that towing pin is strengthened longeron joins with front and back beam vertical respectively, front and back crossbeam is " L " type or " C " type structure, the two ends of front and back crossbeam offer bolt mounting holes, on semitrailer crossbeam, be connected with crossbeam connecting rack, described front and back crossbeam is connected with crossbeam connecting rack by bolt.Towing pin is strengthened longeron both sides and is welded with four connecting racks, this connection bracket is " L " shape structure, four described connecting racks strengthen longeron with traction pin plate, towing pin and front and back beam welding is connected, and four connecting racks are fixedly connected with the underrun bolt of crossbeam connecting rack.
When use, traction pin plate 1, towing pin are strengthened longeron 2, front and back crossbeam 3 and connecting rack 4 and are welded as a component assembly, between this component assembly and semi-trailer frame, assemble and connect, this structure is more suitable for the production model of batch manufacturing, strange land assembling than welded structure, and can not produce weld defect, be convenient for changing even if parts damage yet.Owing to being provided with locating dowel pin structure, in the time of vehicle acceleration or emergency braking, locating dowel pin structure can prevent that attachment bolt herein from bearing excessive shearing force.
On semitrailer crossbeam 5, be welded with crossbeam connecting rack 7, this crossbeam connecting rack 7 is positioned at the towing pin top of web of grider inner side, 2 of every sides, be symmetrically welded, the side of this crossbeam connecting rack 7 and bottom surface are connected with the front and back crossbeam 3 and connecting rack 4 bolts that are welded on traction pin plate top respectively, open circular hole or elliptical aperture with front and back crossbeam 3, connecting rack 4 surfaces that traction pin plate 1 welds, to increase bolted operational space.
