Description

Technical Field

[0001] This utility model relates to the field of pole erecting machine technology, and more specifically, it relates to a counterweight structure for a utility pole erecting machine. Background Technology

[0002] With the widespread use of excavators, the domestic excavator market is rapidly becoming saturated. However, there is still a significant gap in specialized excavators in niche markets. For example, specialized pole erection machines (pole erectors) are mainly used for handling, lifting, drilling, grabbing, and pole erection in power grid auxiliary operations. Because they are required for power grid auxiliary operations, the excavator's tonnage cannot be too large, but the working load must meet the actual needs. Therefore, normal excavators often cannot meet the requirements of power grid auxiliary operations. To meet these requirements, sometimes a relatively heavy additional counterweight is needed, which often leads to an increase in the overall size of the machine and makes assembly difficult.

[0003] Currently, excavator counterweights mainly come in two forms: castings and cast iron. Castings are commonly used in excavators under 6 tons, while cast iron is generally used for excavators over 6 tons. Pole erectors are mainly used for power grid auxiliary operations, and are generally matched with models around 13.5 tons. Although the overall performance of this type of excavator is sufficient, the overall stability of the machine is not very good when lifting utility poles in special locations, so the counterweight should be increased. However, existing excavator counterweights are not convenient to customize the weight according to the working conditions; either the original external dimensions need to be changed, or the weight configuration needs to be matched with significant differences. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the prior art. The purpose of this utility model is to provide a counterweight structure for a utility pole erecting machine.

[0005] The technical solution of this utility model is: a counterweight structure for a utility pole erecting machine, comprising an outer shell, the outer shell including a front cover plate, a rear cover plate, and an upper cover plate and a lower cover plate respectively located on the upper and lower sides of the front cover plate and the rear cover plate. The front cover plate, the rear cover plate, the upper cover plate, and the lower cover plate are welded together. Several layers of middle weight plates are provided in the middle position of the inner side of the front cover plate. The front cover plates on both sides of the middle weight plates are respectively provided with vertically arranged left reinforcing plates and right reinforcing plates. A connecting plate is provided on the lower end of the left reinforcing plates and the side away from the front cover plate. Several layers of left weight plates are provided on the side of the left reinforcing plate away from the middle weight plate, and several layers of right weight plates are provided on the side of the right reinforcing plate away from the middle weight plate. The outer shell is also filled with filling material.

[0006] As a further improvement, the left and right reinforcing plates are provided with through holes.

[0007] Furthermore, a central crossbeam is provided between the left and right reinforcing plates, and side crossbeams and vertical reinforcing beams are provided on both sides of the front cover plate.

[0008] Furthermore, the front cover plate has a vertically symmetrical structure, including a middle plate, and a first inclined plate is provided on both sides of the middle plate. The first inclined plates on both sides extend inclinedly away from the rear cover plate. A second inclined plate is provided on the side of the first inclined plate away from the middle plate, and the second inclined plate extends inclinedly towards the rear cover plate.

[0009] Furthermore, a convex shell is provided at the middle position of the outer side of the front cover plate, and positioning grooves are provided between the two sides of the convex shell and the front cover plate.

[0010] Furthermore, a connecting bracket is provided on the top of the outer side of the front cover plate.

[0011] Furthermore, the rear cover has an arc-shaped structure.

[0012] Furthermore, the left and right reinforcing plates are fully welded to the front cover plate, and the left and right reinforcing plates are fully welded to the connecting plate.

[0013] Furthermore, the middle weight plate, left weight plate, right weight plate and front cover plate are connected by short-segment welding.

[0014] Furthermore, the filling material consists of concrete plus scrap iron blocks or scrap iron filings.

[0015] Beneficial effects Compared with the prior art, the advantages of this utility model are as follows: 1. The counterweight structure of this utility model can effectively customize the weight according to customer needs, unlike traditional methods which only adjust the filling material (concrete, scrap iron blocks, scrap iron filings, etc.) poured into the shell. Traditional methods often limit the maximum density of the filling material to approximately 4500 kg / m³, while the counterweight structure of this utility model can achieve a filling material density of approximately 7000 kg / m³. This utility model allows for convenient weight customization by adjusting the number of center, left, and right counterweight plates according to working conditions without altering the original external dimensions.

[0016] 2. The counterweight structure of this utility model is not simply about increasing the density of the filling material. The key lies in the arrangement and reinforcement of its internal structure. The left and right reinforcing plates in the middle reinforce the structure to establish a strong foundation inside the shell. The middle, left, and right weight plates can adjust the weight and ensure that the center of gravity is centered. The middle crossbeam, side crossbeams, and vertical reinforcing beams ensure the integrity and strength of the shell, and are welded together to ensure the strength of the interior and the shell.

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0020] See Figures 1-4 A counterweight structure for a utility pole erecting machine includes an outer shell 1. The outer shell 1 includes a front cover plate 2, a rear cover plate 5, and an upper cover plate 4 and a lower cover plate located on the upper and lower sides of the front cover plate 2 and the rear cover plate 5, respectively. The front cover plate 2, the rear cover plate 5, the upper cover plate 4, and the lower cover plate are welded together. Several layers of intermediate weight plates 6 are provided in the middle of the inner side of the front cover plate 2. Vertically arranged left reinforcing plates 7 and right reinforcing plates 8 are provided on the front cover plates 2 on both sides of the intermediate weight plates 6. A connecting plate 9 is provided on the lower end of the left reinforcing plates 7 and the right reinforcing plates 8 away from the front cover plate 2. The left reinforcing plates 7, the right reinforcing plates 8, and the connecting plate 9 form a partially enclosed internal reinforcing structure, which can effectively improve the working strength of the front cover plate 2. The intermediate weight plates 6 are located within this internal reinforcing structure. Several layers of left reinforcing plates 10 are provided on the left reinforcing plates 7 away from the intermediate weight plates 6, and several layers of right reinforcing plates 11 are provided on the right reinforcing plates 8 away from the intermediate weight plates 6. The counterweight weight is adjusted by setting the number of weight plates at three positions: center weight plate 6, left reinforcing plate 7, and right reinforcing plate 8, according to requirements, ensuring that the overall center of gravity of the counterweight is in the middle of the installation point. The outer shell 1 is also filled with a filling material consisting of concrete and scrap iron blocks or scrap iron filings, which allows for fine-tuning of the counterweight, thus enabling precise adjustment of its weight.

[0021] The left reinforcing plate 7 and the right reinforcing plate 8 have through holes 12, which facilitates the flow of filling material and keeps the filling material intact throughout the inner cavity of the outer shell 1.

[0022] A central crossbeam 13 is provided between the left reinforcing plate 7 and the right reinforcing plate 8, and side crossbeams 14 and vertical reinforcing beams 15 are provided on both sides of the front cover plate 2, which can further improve the working strength of the front cover plate 2.

[0023] Specifically, the front cover plate 2 has a vertically symmetrical structure, including a middle plate 16. The middle plate 16 has a first inclined plate 17 on each side. The first inclined plates 17 on both sides extend inclinedly away from the rear cover plate 5. The side of the first inclined plate 17 away from the middle plate 16 has a second inclined plate 18. The second inclined plate 18 extends inclinedly towards the rear cover plate 5. The rear cover plate 5 has an arc-shaped structure. The front cover plate 2 and the rear cover plate 5 enclose the internal space of the outer shell 1.

[0024] A convex shell 19 is provided at the middle position of the outer side of the front cover plate 2. Positioning grooves 20 are provided between the two sides of the convex shell 19 and the front cover plate 2 for easy positioning and installation. A connecting bracket 21 is provided at the top of the outer side of the front cover plate 2. The outer shell 1 can be installed onto the pole erecting machine body 22 by using the connecting bracket 21 and bolts. Figure 4 As shown, the lower cover plate is installed on the platform of the pole erecting machine body 22, and the front cover plate 2 is locked to the pole erecting machine body 22 by connecting brackets 21 and bolts. The dimensions of the front cover plate 2 and the rear cover plate 5 can be determined according to the external dimensions of the pole erecting machine body 22, so that the counterweight structure of this utility model not only does not need to change the original external dimensions, but also can be easily customized to meet the weight requirements of the working conditions.

[0025] In this embodiment, the left reinforcing plate 7 and the right reinforcing plate 8 are fully welded to the front cover plate 2, and the left reinforcing plate 7 and the right reinforcing plate 8 are also fully welded to the connecting plate 9 to ensure working strength. The middle weight plate 6, the left weight plate 10, the right weight plate 11 are connected to the front cover plate 2 by short-segment welding to take into account processing efficiency.

[0026] The weight adjustment of this utility model is located inside the shell, which can ensure that the external dimensions of the counterweight remain unchanged, thus not affecting the overall shape of the machine and the working conditions it meets. At the same time, the components inside the shell are all welded together, which further ensures the load-bearing capacity of the counterweight shell and guarantees the reliability of the counterweight.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
