Description

Technical Field

[0001] This utility model relates to the field of excavator technology, specifically to a urea tank support assembly structure. Background Technology

[0002] In order to improve air quality and reduce pollutant emissions, the country has continuously upgraded the emission standards for non-road mobile machinery. The implementation of the National IV emission standard has imposed stricter emission requirements on excavators. Therefore, most excavators have been equipped with after-treatment devices to reduce emissions.

[0003] Currently, there are two main after-treatment technology routes for excavators that meet the China IV emission standard: one is the DOC+DPF+SCR route, and the other is the EGR+DOC+DPF route. The main difference between the SCR and EGR routes is the different methods of controlling NOx emissions. The SCR route uses urea to react with NOx in the exhaust gas, thereby reducing NOx emissions. This requires adding a urea injection device to the after-treatment assembly and adding urea supply devices such as urea tanks and urea pumps to the vehicle.

[0004] The placement of the urea tank on the excavator has become an important aspect of adopting the SCR technology route. Since the urea tank is mainly made of polyethylene, it cannot be directly fixed to the excavator. Therefore, it is necessary to redesign the urea tank bracket to fix the urea tank on the excavator, protect it from the vibration and impact of the whole vehicle, and avoid wear or cracking of the urea tank.

[0005] Therefore, designing a structure that is easy to install, has good shock absorption, and can be applied to urea tanks of different heights is the problem that the inventors want to solve. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated control system for wheeled excavators that offers convenient installation, good shock absorption, and applicability to urea tanks of varying heights.

[0007] The technical solution adopted by this invention to solve its technical problem is: a urea tank support assembly structure, which includes a base plate, connecting holes at the four corners of the base plate, mounting holes on the sides of the connecting holes, a central hole at the center of the base plate, a sliding groove at one edge of the upper surface of the base plate, a movable support slidably mounted on the inner side of the sliding groove, a fixed support fixedly mounted on the base plate on the side opposite to the movable support, two symmetrically distributed locking holes on the end face of the sliding groove, two symmetrically distributed strip holes on the movable support opposite to the locking holes, locking bolts inside the strip holes with their lower ends passing through the locking holes and locked by locking nuts, long cylindrical nuts inside the mounting holes, two symmetrically distributed U-shaped bands on the upper part of the base plate, hook structures at both ends of the U-shaped bands, elliptical holes at the lower ends of the hook structures, T-bolts inside the hook structures and elliptical holes, and four T-bolts threadedly connected to four long cylindrical nuts respectively.

[0008] Furthermore, side rubber pads are provided on the opposite end faces of the movable bracket and the fixed bracket.

[0009] Furthermore, a rubber sleeve is provided on the outer side of the U-shaped band.

[0010] Furthermore, a bottom rubber pad is provided in the middle of the upper end surface of the base plate.

[0011] Furthermore, the bottom rubber pad has a hole in the middle that is the same size, shape and position as the central hole.

[0012] Furthermore, the elongated nut includes an external hexagonal nut, the end of which is connected to an elongated cylinder, which has a cylindrical structure and internal threads on its inner side.

[0013] Furthermore, the T-bolt includes an L-shaped body, with an external thread on the lower outer side of the L-shaped body and an internal thread on the upper side of the L-shaped body. A movable pin is connected to the inner side of the internal thread, and an internal hexagonal socket is provided at one end of the movable pin.

[0014] Furthermore, the connecting hole is connected to the excavator frame via bolts.

[0015] The beneficial effects of this utility model are: 1.

[0023] The side of the connecting hole 9 is provided with a mounting hole 10, the center hole 2 is provided at the center of the base plate 1, and a sliding groove 4 is provided at one edge of the upper surface of the base plate 1. A movable bracket 5 is slidably provided on the inner side of the sliding groove 4. The sliding groove 4 can be used to quickly position the movable bracket 5, which is convenient for quick installation and assembly. A fixed bracket 8 is fixedly provided on the side of the base plate 1 opposite to the movable bracket 5. The fixed bracket 8 is preferably fixed to the base plate 1 by welding. The fixed bracket 8 and the movable bracket 5 cooperate from both sides to clamp and limit the urea tank installed between them from both sides.

[0024] Two symmetrically distributed locking holes are provided on the end face of the slide 4. Two symmetrically distributed strip holes 6 are provided on the movable bracket 5 opposite to the locking holes. Locking bolts are provided inside the strip holes 6, and the lower end of the locking bolts passes through the locking holes and is locked by locking nuts. By loosening the locking nuts, the relative position of the movable bracket 5 and the slide 4 can be adjusted, which makes it easier to set up the urea tank and perform clamping operations.

[0025] A long cylindrical nut 13 is provided inside the mounting hole 10. Two symmetrically distributed U-shaped bands 11 are provided above the base plate 1. Both ends of the U-shaped bands 11 are provided with hook structures 17. An elliptical hole 15 is opened at the lower end of the hook structure 17.
