Abstract
The utility model discloses a front gantry connecting device with a water tank of a semi-hung logging transporter. The front gantry connecting device with the water tank of the semi-hung logging transporter is used to improve a rigidity device at the connecting portion of a bolt. A pad pipe is arranged at the head of the bolt and the connecting portion, the length of pad pipe 3 is 50-80 millimeters, and the diameter of the pad pipe 3 is greater than that of the bolt. Because the pad pipe is added in the front gantry connecting device with the water tank of the semi-hung logging transporter, a connecting bolt is lengthened and extension quantity of the bolt is increased under tension, and therefore, the rigidity at the connecting portion of the bolt is effectively decreased, the impact of a turning torque arising from shaking the water tank on a wing plate and a connecting plate of a subframe at the connecting portion is reduced, abrasion at the connecting portion is decreased, and a side reversal torque borne by a chassis of a transporter is effectively lowered.
Description
Technical field
The utility model relates to a kind of connecting device, the preceding gantry of particularly a kind of semi-trailer logging transporter band water tank connecting device.
Background technology
In the lumber Transporting, use the semi-trailer logging transporter to transport timber from the forest zone usually, because load-carrying is big, and road conditions are special, need constantly braking for a long time, and this just needs the wheel hub water spray system to work without cessation, and thus, just need be equipped with high-capacity water tank.Usually the vehicle water tank is the following both sides that hang over vehicle frame, but logging transporter often will be in the forest zone or the road driving in mountain area, and road conditions are complicated, are easy to just water tank rubbed accidentally.In order to address this problem, the applicant has proposed to be provided with preceding gantry of water tank on the same day, water tank is located at the bottom in preceding gantry that is:, arranges bolt in subframe through two of pin place, water tank both sides.During vehicle ', because of road conditions bad, wigwag motion; At this moment, water tank can and then rock owing to be filled with water; Produce overturning couple, because bolted connection place rigidity is bigger, so all can produce bigger impulsive force to major and minor vehicle frame wing plate in junction and connecting panel easily this moment; Cause the major and minor chassis side rail wing plate at bolted connection place to be out of shape, to tear easily, increase the weight of the suffered side torque reaction of main chassis.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of bolted connection place rigid mount that improves, and can effectively reduce bolted connection place rigidity, reduces water tank and rocks the impulsive force of the overturning couple of generation to major and minor vehicle frame wing plate in junction and connecting panel.
The utility model is realized through following technical scheme:
The preceding gantry of semi-trailer logging transporter band water tank connecting device; Comprise preceding gantry Connection Block, subframe, main car frame; Be connected to preceding gantry Connection Block and subframe longeron wing plate; And the bolt between subframe and the main car frame longeron wing plate, the nut of bolt and preceding gantry Connection Block, and the joint face of subframe longeron wing plate between be provided with the pad pipe.
The length of said pad pipe is the 50-80 millimeter.
The somewhat larger in diameter of said pad pipe is in the diameter of bolt.
The utility model compared with prior art has following advantage:
The utility model makes the tie bolt lengthening; The extension quantitative change of bolt is big when being drawn; Can effectively reduce bolted connection place rigidity; Reduce water tank and rock the impulsive force of the overturning couple of generation, reduce the junction wearing and tearing, effectively reduce the suffered side torque reaction of main chassis major and minor vehicle frame wing plate in junction and connecting panel.
Description of drawings
Fig. 1 is the utility model scheme drawing.
Fig. 2 is the utility model working state schematic representation.
1. bolts among the figure, 2. nut 3. fills up pipe, 4. preceding gantry, 5. Connection Block, 6. subframe, 7. main car frame.
The specific embodiment
As shown in Figure 2; The utility model comprises preceding gantry Connection Block 5, subframe 6, main car frame 7; Be connected to preceding gantry Connection Block 5 and subframe longeron wing plate; And the bolt 1 between subframe 6 and the main car frame longeron wing plate, it is characterized in that: the nut 2 of bolt 1 and preceding gantry Connection Block 5, and the joint face of subframe longeron wing plate between be provided with the pad pipe.
The length of said pad pipe 3 is the 50-80 millimeter.The somewhat larger in diameter of said pad pipe 3 is in bolt 1 diameter.
Still as shown in Figure 2, preceding gantry is fixed on the subframe, and subframe is fixed on the main car frame, and preceding gantry produces overturning couple owing to have water tank when rocking, near the overturning couple that receives maximum.Because the utility model makes the tie bolt lengthening; The extension quantitative change of bolt is big when being drawn; Can effectively reduce bolted connection place rigidity; Reduce water tank and rock the impulsive force of the overturning couple of generation, reduce the junction wearing and tearing, effectively reduce the suffered side torque reaction of main chassis major and minor vehicle frame wing plate in junction and connecting panel.
Claims (3)
