Description

Technical Field

[0001] The utility model relates to the technical field of operating machinery, in particular to a radiator installation component and an operating machinery. Background Art

[0002] At present, most engine manufacturers only provide fans, and the wind shield is provided by the main engine manufacturer of the operating machinery. There are two points to consider when matching the wind shield and the fan. The first point is that the wind shield constrains the flow field and provides a higher air intake efficiency, and the gap between the fan and the wind shield is as small as possible; the second point is that considering the installation and manufacturing errors, the larger the gap is, the better. In order to balance these two points, the adjustment gap between the fan and the wind shield is generally 15mm to 20mm, and the adjustment margin is small. Due to the welding error of the engine vertical plate, the welding error of the engine bracket, the deformation error of the suspension cushion, and the welding error of the radiator support, the center of the engine fan and the center line of the wind shield will form an angle, causing the fan and the wind shield to collide, thereby causing damage to the fan and the radiator.

[0003] In the related art, the wind shield is fixed on the radiator, and the radiator mounting assembly includes a heat sink and a heat sink bracket. The radiator is fixed on the vehicle frame through the radiator mounting assembly, the heat sink bracket is fixed on the vehicle frame, and the heat sink bracket is fixed on the radiator. The heat sink bracket is provided with front and rear long holes extending in the front and rear direction, and the heat sink bracket is provided with left and right long holes extending in the left and right direction. Bolts pass through the front and rear long holes and the left and right long holes and are connected with nuts. The positions of the radiator and the wind shield are adjusted front and rear and left and right through the front and rear long holes and the left and right long holes. However, the radiator mounting assembly cannot achieve the up and down adjustment of the radiator. Due to different engine inclination angles and positions, many new heat sink brackets need to be produced, resulting in a lot of materials that are not easy to distinguish, welding is prone to errors, and a lot of time is wasted in processing.

The position of the radiator 12 in the up-down direction is adjusted by adjusting the position of at least two second locking members 5 on the second end of the support rod 4. The position of the radiator 12 in the left-right direction is adjusted by adjusting the position of the second end of the support rod 4 in the second adjustment hole 204. The position of the radiator 12 in the front-to-back direction is adjusted by the position of the first locking member 3 in the first adjustment hole 203, thereby realizing the position of the radiator 12 in three directions, thereby adjusting the up-down, front-to-back, and left-to-right positions of the wind shield 14 fixed on the radiator 12.

The length L7 of the smooth rod section is greater than the distance L4 between the outer surface of one side plate 102 and the inner surface of the other side plate 102, wherein D2-1mm<D5<D2-0.5mm. The setting of L7>L4 facilitates the connection between the mounting pin 6 and the anti-slipping piece. The diameter of the smooth rod section is smaller than the diameter of the first hinge hole 4011, so that the mounting pin 6 is easy to install. The setting of the pin head 602 and the anti-slipping piece prevents the mounting pin 6 from falling off the fixed support 1.

[0054] Further, the anti-dropping member is a mounting nut 7, which is welded on the outer surface of a side plate 102. Preferably, the mounting nut 7 is welded on the side plate 102 close to the radiator 12. It can be understood that the mounting nut 7 may not be welded on the side plate 102.

[0055] In another embodiment, the mounting pin 6 is a movable latch such as a cotter pin.

[0056] In one embodiment, the second locking member 5 is a nut, and the support rod 4 has a threaded structure, which is threadedly connected to the nut. By adjusting the position of the nut on the threaded structure, the upper and lower positions of the radiator 12 and the wind shield 14 can be adjusted. When adjusting, you only need to screw the nut, which is simple and labor-saving.

[0057] Specifically, the first locking member 3 is a bolt or a screw, and in this case, a threaded hole is provided on the heat sink 12 .

[0058] It should be noted that in Figure 4 In the figure, L1 is the length of the threaded structure, L2 is the distance between the center of the first hinge hole 4011 and the end face of the threaded structure, Figure 7 In the figure, L5 is the length of the threaded section and L7 is the length of the polished rod section.

The second end of the support rod 4 can be firmly fixed on the mounting bracket 2 through the three nuts. Two of the three nuts are flange nuts 501, and the other is an ordinary locking nut 502. One flange nut 501 is located above the second adjustment hole 204, and the other flange nut 501 is located below the second adjustment hole 204. The locking nut 502 is located below the lower flange nut 501. The arrangement of the flange nut 501 can increase the contact area, so that the force is small.

[0074] Assuming that the support rod 4 is made of Q345B (yield strength 345Mp), with a diameter of 20mm, and the water tank is filled with 80kg of antifreeze, the shear force of the support rod 4 is F=mg / (r*r*π)=80*10 / (10*10*π)=2.55Mpa, which is much smaller than the material strength; the thread force of the support rod 4 is σ=F / A≤[σ], where F is the tensile force and A=π(dH / 6)^2 (empirical formula); for a 60° triangular thread, H=0.866p, and for trapezoidal and rectangular threads, H=0.5p, d is the thread minor diameter, H is the thread tooth height, and p is the pitch. It is calculated that the thread force of the support rod 4 is much smaller than the force required for the thread.
