Description

Technical Field

[0001] This utility model relates to a detachable traction counterweight, belonging to the field of engineering machinery technology. Background Technology

[0002] When an excavator is working on flat ground, its stability mainly relies on the counterweight for balance. However, when an excavator is working on steep slopes in mountainous areas, it needs strong climbing ability. The counterweight is generally quite heavy, which increases the overall weight of the excavator and reduces its climbing ability.

[0003] Currently, the counterweights on excavators are mainly divided into two types: filled counterweights and cast counterweights. Both filled and cast counterweights are integral pieces that cannot be easily disassembled, and their function is also very limited. They can only be used to balance the stability of the excavator and have no auxiliary effect when the excavator is climbing steep slopes, nor can they improve the excavator's climbing ability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a detachable towing counterweight. When an excavator needs to climb a steep slope, this counterweight can be removed to reduce the overall weight of the machine. Simultaneously, this counterweight has a towing function, providing assistance during the excavator's climb and enhancing its climbing ability. Once the excavator equipped with this counterweight reaches the top of the slope, it can also assist in towing other equipment to the top of the slope, or towing other equipment along the edge of the slope while performing operations.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1 , Figure 2 As shown, this utility model provides a detachable traction counterweight, mainly used in engineering vehicles such as excavators. It includes a counterweight base 1, a winch 2, a pin 3, a secondary counterweight 4, a left frame 5, a right frame 6, a cover plate assembly 7, a baffle 8, and a skin assembly 9. The counterweight base 1 is mounted on a turntable and is the main carrier of the detachable traction counterweight. The winch 2 is fixed to the middle of the counterweight base 1 via the pin 3 and is the main carrier for realizing the traction function of the detachable traction counterweight. The left frame 5 and right frame 6 are both frame structures and are respectively mounted on the left and right sides of the counterweight base 1. On the right sides; there are two secondary counterweights 4, symmetrically installed on both sides of the counterweight base 1, located between the left frame 5 and the right frame 6; the cover plate assembly 7 is located directly above the counterweight base 1, and its outer contour is the same as that of the counterweight base 1.

Simultaneously, this counterweight has a towing function, providing assistance during the excavator's climbing process and enhancing its climbing ability. After the excavator equipped with this counterweight reaches the top of the slope, it can also assist in towing other equipment to the top of the slope, or towing other equipment along the edge of the slope while operating.

[0026] The following provides a further explanation of the specific structure of the aforementioned counterweight base.

[0027] like Figure 3 As shown, the counterweight base 1 is equipped with a lifting lug 11, a double lug support 12, a limiting block 13, and a sleeve 14, etc.

[0028] Specifically: the top surface of the counterweight base 1 is provided with two lifting lugs 11, which can be used to lift the counterweight base 1, and can also be used to lift the detachable traction counterweight as a whole; the middle area of ​​the top surface of the counterweight base is provided with four double-ear supports 12, and the double-ear supports 12 are provided with hinge holes I. The winch is provided with four single-ear supports that correspond one-to-one with the double-ear supports 12, and the single-ear supports are provided with hinge holes II. The single-ear supports are inserted into the double-ear supports 12. After the hinge holes I and II are aligned, the pin 3 is inserted to fix the winch 2 and the counterweight base 1 together. A protruding limiting block 13 is fixed at the center of the part where the left frame 5 and the right frame 6 are installed on the top surface of the counterweight base 1. The limiting block 13 is used to limit the sub-counterweight 4 and can also play a guiding role during the installation of the sub-counterweight 4. At least one hollow sleeve 14 is pre-embedded in the part where the left frame 5 and the right frame 6 are installed in the counterweight base 1, and the sleeve 14 passes through the counterweight base 1 from top to bottom, so that the mounting bolts of the sub-counterweight 4 can pass through.

[0029] The following provides a further explanation of the specific structure of the aforementioned secondary counterweight.

[0030] like Figure 4 , Figure 5 As shown, the secondary counterweight 4 is a casting, and the whole is a regular cuboid. The top surface of the secondary counterweight 4 has two symmetrically embedded lifting thread seats 41 for installing lifting rings. The bottom center of the secondary counterweight 4 has a positioning hole seat 42 for cooperating with the limiting block 13 on the counterweight base 1. The positioning hole seat 42 has four symmetrically embedded mounting thread seats 43 around it for installing bolts.

[0031] The following provides a further explanation of the specific structure of the aforementioned cover plate assembly.

[0032] like Figure 6As shown, the cover plate assembly 7 includes a main cover plate 71, which mainly serves as a support.
