Description
Technical Field
[0001] The utility model relates to the field of excavator rocker arms, in particular to a rocker arm supporting structure of an excavator. Background Art
[0002] Excavator rocker arm support refers to the support structure that needs to be set up on the excavator in order to ensure the safety, stability and operating efficiency of the excavator during operation. It mainly includes rocker arm frames, brackets, columns, etc. The rocker arm frame is a structure used to support the arm length on the excavator. It is usually made of high-strength steel and can be adapted to different excavator models and arm lengths by adjusting the size and position of the bracket. The role of the rocker arm frame can effectively reduce the instability caused by different arm lengths during the operation of the excavator, thereby improving the safety and stability of the excavator.
[0003] The rocker arm of an excavator is generally controlled by a cylinder. During use, the cylinder is under heavy burden. If the cylinder suddenly fails and loses control, the rocker arm posture cannot be maintained. Utility Model Content
[0004] The utility model aims to provide a rocker arm supporting structure of an excavator to solve the above technical problems.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rocker arm support structure of an excavator, including an extended base, a bracket, a hinge groove, a pin hole, a cantilever cylinder, a sliding hole, a slide plate, and a support and slow-down structure. The bracket is fixed at the front of the top of the extended base, the hinge groove is opened at the top of the bracket, the pin hole opens the hinge groove through the bracket, and the bracket is hinged to the bottom of the rocker arm through the pin hole, the cantilever cylinder is hinged to the front bottom of the bracket, the sliding hole is opened in the middle of the front end of the extended base, the slide plate is slidably connected to the extended base through the sliding hole, and the support and slow-down structure is installed at the front of the top of the slide plate.
[0006] On the basis of the above technical scheme, the supporting slow descent structure includes a slide cylinder, a cylinder mouth, an air hole rubber pad, a slide column, an air hole, and a rocker arm hinge. The slide cylinder is fixed to the front of the top of the slide plate, the cylinder mouth is arranged at the top of the slide cylinder, the air hole rubber pad is distributed at the front and rear ends of the slide cylinder, the slide column is slidably connected to the slide cylinder through the cylinder mouth, the air holes are respectively opened at the front and rear ends of the slide column, and the air holes correspond to the air hole rubber pads, the rocker arm hinge is installed on the top of the slide column, and the slide column is hinged to the middle of the rocker arm through a hinge.
[0007] Based on the above technical solution, the pore rubber pad blocks air from passing through the pores to achieve slow descent of the sliding column support.
[0008] Compared with the prior art, the utility model has the following advantages: the base for installing the rocker arm bracket is lengthened and slidably connected to the slide plate, on which a support slow-descent structure is installed and hinged to the middle of the rocker arm, thereby achieving slow-descent support for the rocker arm and sharing the pressure when the oil cylinder suddenly loses control, thereby avoiding accidents caused by sudden drop of the rocker arm.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] like Figures 1 to 3 As shown, a rocker arm support structure of an excavator includes an extended base 1, a bracket 2, a hinge groove 3, a pin hole 4, a cantilever cylinder 5, a sliding hole 6, a slide plate 7, and a support slow-down structure 8. The front top of the extended base 1 fixes the bracket 2, the hinge groove 3 is opened at the top of the bracket 2, the pin hole 4 opens the hinge groove 3 through the bracket 2, and the bracket 2 is hinged to the bottom of the rocker arm through the pin hole 4, the cantilever cylinder 5 is hinged to the front bottom of the bracket 2, the sliding hole 6 is opened in the middle of the front end of the extended base 1, the slide plate 7 is slidably connected to the extended base 1 through the sliding hole 6, and the support slow-down structure 8 is installed at the front top of the slide plate 7.
[0015] The supporting slow-descent structure 8 includes a slide tube 9, a tube mouth 10, an air-hole rubber pad 11, a slide column 12, an air hole 13, and a rocker arm hinge 14. The slide tube 9 is fixed to the front of the top of the slide plate 7. The tube mouth 10 is arranged at the top of the slide tube 9. The air-hole rubber pad 11 is distributed at the front and rear ends of the slide tube 9. The slide column 12 is slidably connected to the slide tube 9 through the tube mouth 10. The air holes 13 are respectively opened at the front and rear ends of the slide column 12, and the air holes 13 correspond to the air-hole rubber pad 11. The rocker arm hinge 14 is installed on the top of the slide column 12, and the slide column 12 is hinged to the middle of the rocker arm through the hinge 14.
[0016] The pore rubber pad 11 blocks air from passing through the pores 13 to support the sliding column 12 to descend slowly.
[0017] The working principle of the utility model is as follows: when in use, when the cantilever cylinder 5 suddenly fails and loses support for the rocker arm, the rocker arm presses the slide column 12 downward and backward along the hinge groove 3. While the slide column 12 slides backward along the slide hole 6 along the slide plate 7, the slide column 12 is pressed down on the slide cylinder 9 along the cylinder mouth 10. The air in the slide cylinder 9 is compressed and discharged along the air hole 13. The air discharge amount is controlled by the blocking of the air hole rubber pad 11, so as to achieve the support and slow descent of the rocker arm and avoid accidents caused by sudden descent.
[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
