Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron weight technology, specifically an iron weight that is easy to quickly limit and fix. Background Technology
[0002] In the overhead contact system of electrified railways, the weights, as the core components of the compensation device, directly affect the stability and safety of train current collection by balancing the tension of the contact wire and the catenary through their own weight. At present, iron weights are widely used due to their stable weight and strong adaptability to size, but existing products still have many limitations in actual use.
[0003] The existing iron weight limit and fixing structure often relies on complex connecting parts such as bolts and clips. During installation, special tools are needed to connect and fix them one by one, which is time-consuming and labor-intensive. When it is necessary to inspect or adjust the number of weights, the disassembly process is equally cumbersome. This not only increases the workload of maintenance personnel but also prolongs the operation time and affects the efficiency of railway transportation. Furthermore, the limiting components of existing iron weights are mostly fixed structures, which cannot be flexibly adjusted according to actual installation needs and are difficult to adapt to the limiting and fixing requirements under different working conditions. At the same time, some structural designs make it difficult to disassemble and replace components individually. If a limiting component is damaged, the entire weight may need to be replaced, which increases maintenance costs. Therefore, a new solution is needed to solve this problem. Utility Model Content
[0004] In view of the above-mentioned background technology, there are shortcomings and defects in the existing technology, such as poor stability.
[0005] The present invention discloses an iron weight that is easy to quickly limit and fix, comprising a main body, a slider 1 slidably disposed on the main body, a slider 2 disposed between the slider 1 and the main body, a fixing member disposed between one end of the slider 1 and the slider 2 and the main body, an installation groove disposed on one side of the main body, a connecting block mounted on the upper end of the main body, and a connecting groove corresponding to the connecting block disposed on the lower end of the main body.
[0006] Furthermore, the main body and the connecting block are integrally formed, a protrusion is provided above the mounting groove, and the protrusion and the connecting block are fixedly connected by an arc-shaped baffle. The protrusion, the arc-shaped baffle and the main body are all integrally formed.
[0007] Furthermore, both the protrusion and the slider are U-shaped, and there are two connecting blocks symmetrically arranged on the main body. A groove is provided between the protrusion and the two connecting blocks, and the slider slides along the groove.
[0008] Furthermore, the slider one is provided with a slide groove two, the upper end face of the slide groove two is on the same plane as the upper end face of the protrusion, the slider two is slidably disposed with the slide groove two, and the slider two is configured as "U" shaped.
[0009] Furthermore, the fixing component includes a fixing rod, and multiple fixing rods are provided. The multiple fixing rods are respectively installed on one end of the slider one and the slider two near the arc-shaped baffle. The arc-shaped baffle at the corresponding position of the fixing rod is provided with a through hole, one end of the fixing rod passes through the through hole, and a limit rod is inserted into the fixing rod.
[0010] Furthermore, the limiting rod is vertically positioned, and the limiting rod is fixedly connected to the main body via a connecting rope.
[0011] Furthermore, both slider one and slider two are provided with a disassembly ring at the end away from the arc-shaped baffle, and both slider one and slider two are provided with a threaded hole, and the disassembly ring is threadedly connected to the threaded hole.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves rapid installation and fixation of the iron weight limiting component by using sliding cooperation between slider one and slider two and the main body, along with a fixing rod and a limiting rod to form a fixing component, without the need for complicated tools; during disassembly, only the limiting rod needs to be removed, and the slider can be separated by pulling the disassembly ring, which greatly shortens the operation time of installation, maintenance and replacement, and reduces the workload of maintenance personnel; at the same time, the slider and other components can be disassembled and replaced individually, avoiding the need to replace the entire weight due to local damage, effectively saving maintenance costs.
[0013] 2. This utility model adopts a sliding fit structure of "U"-shaped slider and groove, which can flexibly adjust the number of sliders according to actual installation requirements and adapt to the limit fixing requirements under different working conditions; and the precise fit between the connecting block and the connecting groove, and the integrated setting of the arc baffle and the protrusion can effectively eliminate the connection gap, reduce the wear caused by shaking, and enhance the overall stability after multiple weights are stacked, thereby ensuring the tension balance of the electrified railway catenary system and the safety of train current collection.

[0016] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.
[0017] Please see Figure 1 , Figure 3 The present invention relates to a quick and easy fixed iron weight, comprising a main body 1, on which a slider 3 is slidably mounted, and a slider 4 is disposed between the slider 3 and the main body 1. The sliders 3 and 4 are made of wear-resistant alloy steel and are polished to reduce sliding resistance. A fixing member is provided between one end of the sliders 3 and 4 and the main body 1. The fixing member includes a fixing rod 13, and multiple fixing rods 13 are provided. The multiple fixing rods 13 are respectively installed at the end of the sliders 3 and 4 near the arc-shaped baffle 7.
[0018] See Figure 3 , Figure 4 As shown, a through hole 14 is provided on the arc-shaped baffle 7 at the corresponding position of the fixing rod 13. One end of the fixing rod 13 passes through the through hole 14, and a limit rod 15 is inserted into the fixing rod 13. The limit rod 15 is set vertically, and the limit rod 15 is fixedly connected to the main body 1 by a connecting rope 16. The connecting rope 16 is a high-strength nylon rope to avoid breakage due to long-term stress. An installation groove 2 is provided on one side of the main body 1. The installation groove 2 is set in a "U" shape. A connecting block 5 is installed on the upper end of the main body 1. The main body 1 and the connecting block 5 are set as one piece.
[0019] In this embodiment, a protrusion 8 is provided above the mounting groove 2. The protrusion 8 and the connecting block 5 are fixedly connected by an arc-shaped baffle 7. The protrusion 8, the arc-shaped baffle 7 and the main body 1 are all integrally formed. The protrusion 8 is provided with a mounting hole. By passing the connecting rod through the mounting hole, the superimposed main body 1 can be further limited, thereby improving the stability of the connection between the main bodies 1. The ends of slider 1 3 and slider 2 4 away from the arc-shaped baffle 7 are provided with a disassembly ring 12. Slider 1 3 and slider 2 4 are provided with threaded holes 11. The disassembly ring 12 is threadedly connected to the threaded hole 11.
[0020] See Figure 1 , Figure 3 , Figure 4 As shown, both the protrusion 8 and the slider 3 are U-shaped. There are two connecting blocks 5, which are symmetrically arranged on the main body 1. A groove 9 is provided between the protrusion 8 and the two connecting blocks 5. The slider 3 slides along the groove 9. A second groove 10 is provided on the slider 3. The upper end face of the second groove 10 is on the same plane as the upper end face of the protrusion 8. The second slider 4 slides along the second groove 10. The upper end of the second slider 4 is on the same plane as the upper end of the slider 3.
[0021] See Figure 1 , Figure 2 The slider 2 4 is set in a "U" shape. The lower end of the main body 1 is provided with a connecting groove 6 corresponding to the connecting block 5. The outer wall of the connecting block 5 and the inner wall of the connecting groove 6 are precisely fitted, and the contact surfaces of both are smooth. The distance from the upper end face of the connecting block 5 to the upper end face of the slider 1 3 is consistent with the depth of the connecting groove 6, ensuring that when multiple iron weights are stacked, the upper and lower main bodies 1 can fit together completely, avoiding tilting or shaking caused by height difference.
[0022] The implementation principle is as follows: When installing slider 3, slider 3 slides along the slide groove 9 on the main body 1 and moves to the preset position. Then, slider 4 is installed and slides along the slide groove 10 and moves to the top of the protrusion 8. After slider 3 and slider 4 are adjusted into place, the fixing rod 13 at the end passes through the corresponding through hole 14 on the arc-shaped baffle 7. Then, the limiting rod 15 is vertically inserted into the fixing rod 13 to lock slider 3 and slider 4. At this time, the limiting rod 15 is connected to the main body 1 through the connecting rope 16 to prevent loss during operation, realize the quick fixing of the parts, and ensure that the assembled iron weight is stably stressed. When multiple iron weights are stacked, the upper iron weight body 1 and the lower iron weight body 1 are precisely matched through the connecting groove 6 and the connecting block 5, which quickly achieves the initial positioning of the upper and lower weights, avoids the problem of misalignment in the docking of traditional structures, and improves the docking accuracy. By using the double-layer sliding cooperation of slider 1 3 and slider 2 4, the connection gap can be further eliminated, avoiding wear caused by shaking and enhancing the overall stability after assembly.
[0023] When it is necessary to repair or replace the iron weights, first remove the limiting rod 15 inserted into the fixed rod 13 to release the limiting of slider 3 and slider 4; by pulling the disassembly ring 12, slider 3 and slider 4 are moved away from the arc baffle 7 and separated from the main body 1. At this time, the upper and lower weights can be easily disassembled by separating the connecting block 5 from the connecting groove 6 without complicated tools, which greatly shortens the operation time of repair or replacement and reduces the workload of maintenance personnel.
[0024] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
