Problems solved by technology

[0003] Chinese patent (notification number: CN111206979A) discloses a lightweight aluminum alloy urea tank bracket assembly, which includes a urea tank installed on the frame body and a urea pump assembly installed on the urea tank; the urea tank Installed on the frame body, the frame body includes a front frame bracket, a rear frame bracket connected to the front frame bracket, and a pump body bracket arranged at the front end of the front frame bracket and used for installing the urea pump assembly; the front frame bracket and the rear frame The brackets are connected to form corresponding side frame bodies, a floor frame is set at the lower end between the side frame bodies, and a dustproof cover is set at the upper end between the side frame bodies. This device has a compact structure, but it is practical but inconvenient. Semi-suspension connection, and the center of gravity of the urea tank is low, which is easy to cause deformation and damage to the frame body during driving, and the maintenance of the device and the addition of urea solution need to be removed before the device can be carried out, which is very troublesome

Embodiment 1

[0027] refer to Figure 1~6 , in the embodiment of the present invention, an integrated urea tank bracket assembly, including an L-shaped backboard 3, a fixed buckle 2 is provided on the left side of the L-shaped backboard 3, and the fixed buckle 2 is slidably arranged on the right side of the I-shaped steel 1 On the side narrow wing, bolt holes A4 are symmetrically arranged on both sides of the left wide wing of the I-beam 1, and the device passes through the bolt hole A4, and the I-beam 1 can be fastened to the car body by bolts, and the I-beam 1 A number of threaded holes 5 are provided in the middle position, and the L-shaped back plate 3 is provided with bolt holes B7, the bolt holes B7 correspond to the threaded holes 5, and the device is connected to the threaded holes 5 by bolts, and the bolt holes B7 Corresponding to the arrangement of the threaded holes 5, the L-shaped back plate 3 is fixed on the I-beam 1 by bolts.

Embodiment 2

[0032] refer to Figure 4 The present invention also provides another embodiment. The difference between this embodiment and the above embodiment is that a stopper C25 is provided at the left end of the upper surface of the horizontal plate below the L-shaped backboard 3, and a stopper C25 is provided on the right side of the bottom plate 10. Stopper B24, the connecting rod 14 slides through the stopper B24, and the stopper B24 and the stopper C25 coincide in the horizontal direction, and the device passes through the setting of the stopper B24 and the stopper C25, and the tensile limit of the bottom plate 10 Restriction, because the block B24 and the block C25 coincide in the horizontal direction, when the block B24 follows the bottom plate 10 and stretches to the block C25, the block C25 blocks the block B24 and limits the stretching, which can effectively Prevent the slide rail 9 from derailing due to overstretching and causing damage to the device.

Abstract

The invention relates to a support, and discloses an integrated urea box support assembly. The integrated urea box support assembly comprises an L-shaped back plate, a fixing buckle is arranged on theleft side of the L-shaped back plate and slidably arranged on a narrow wing on the right side of I-shaped steel, side plates are arranged on the two sides of the L-shaped back plate, a sliding grooveis formed in the upper surface of a transverse plate below the L-shaped back plate, a sliding rail is arranged in the sliding groove, a bottom plate is connected to the top end of the sliding rail, and a plurality of bolt fixing blocks are symmetrically connected to the two sides of the bottom plate. According to the integrated urea box support assembly, through combined arrangement of the sliding groove and the sliding rail, an integrated urea box can be stretched out of a vehicle from the lower portion of a vehicle belly under the condition that the integrated urea box is not disassembled,maintenance of the integrated urea box and adding of a urea solution are facilitated, and the practicability of the integrated urea box support assembly is improved.

Description

technical field [0001] The invention relates to a bracket, in particular to an integrated urea tank bracket assembly. Background technique [0002] At present, the pollutants emitted by automobiles mainly include hydrocarbons, nitrogen oxides, carbon monoxide, and particulates. Urea is usually used as a catalyst, and selective catalytic reduction technology (ie, SCR technology) is used to purify pollutants in engine exhaust. Therefore, automobile production The manufacturer needs to design the urea tank. With the implementation of emission standards, the demand for after-treatment of automobile engines has further increased, and the specifications of after-treatment equipment such as urea tanks have increased. For example, at the current stage, the capacity of the urea tank for heavy-duty commercial vehicles under the National V emission standard is about 30L. After the implementation of the National VI emission standard, the urea tank size needs to be increased to about 90...
