Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline dredging technology, and in particular to a pipeline dredging device. Background Technology
[0002] Pipelines are commonly used components in various fields, mainly for transporting fluids, including liquids, gases, or powders. When transporting liquids, if there are many impurities in the liquid and the impurities are large in size, they can easily clog the pipeline. When transporting powders, factors such as high humidity and poor flowability can also cause the powder to clog the pipeline.
[0003] Currently, the applicant's known methods for unblocking pipelines include manual unblocking and equipment unblocking. Equipment unblocking mainly relies on air pressure, delivering high-pressure gas into the pipeline to achieve unblocking, but this method has the disadvantage of high cost. Manual unblocking has the advantage of low cost, but during manual unblocking, the operator mainly uses a dredging rod to pry open the blockage. Although the dredging rod can clear minor blockages, when facing severely blocked pipelines, a single operator often cannot handle the unblocking force, requiring two or more people to work together. This not only increases the complexity of the operation, but also consumes a lot of time and energy.
[0004] Therefore, people urgently need a pipe dredging device that has good dredging effect and is easy to operate. Utility Model Content
[0005] The purpose of this utility model is to provide a pipe unblocking device to solve the problems existing in the prior art. It uses the impact force of the falling hammer block to unblock the blockage with the pointed cone of the unblocking rod, resulting in good unblocking effect and high ease of operation.
[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a pipe dredging device, including a dredging rod and a counterweight block. The dredging rod includes a sliding section, an extension section for extending into the pipe to be dredged, and a pointed cone section for dredging the blockage. The counterweight block is slidably disposed on the sliding section. The extension section is provided with a first blocking part for blocking the counterweight block at one end near the sliding section.
[0007] Preferably, the end of the sliding segment away from the extension segment is provided with a second blocking part for preventing the counterweight block from falling out.
[0008] Preferably, both the first blocking portion and the second blocking portion are annular.
[0009] Preferably, the first blocking part is welded or integrally disposed on the extension section, and the second blocking part is welded or integrally disposed on the sliding section.
[0010] Preferably, at least one handle is provided on the outer peripheral wall of the hammer block.
[0011] Preferably, two handles are provided on the outer peripheral wall of the hammer block, and the two handles are arranged symmetrically.
[0012] Preferably, the end of the handle away from the counterweight is provided with an anti-slip part.
[0013] Preferably, the anti-detachment part is spherical.
[0014] Preferably, both the counterweight and the sliding section are cylindrical, and the counterweight and the sliding section are coaxially arranged.
[0015] Preferably, the extended section is cylindrical.
[0016] The present invention achieves the following main technical effects compared to the prior art:
[0017] Utilizing the characteristic that the weighted block can slide freely on the sliding section of the unblocking rod, during unblocking, the extension section of the unblocking rod is inserted into the pipe to be unblocked, and the pointed cone of the unblocking rod contacts the blockage. Then, the weighted block is pulled up and released. Under its own weight, the weighted block falls and strikes the first blocking part. The impact force is transmitted through the extension section to the pointed cone, causing the pointed cone to penetrate the blockage and thus unblock it. This method not only has a good unblocking effect but also offers high overall ease of operation, saving manpower. In addition, the falling distance of the weighted block can be actively controlled to achieve the purpose of actively controlling the unblocking force. It can be adapted to different blockage situations, increasing the applicability of the device. Furthermore, for minor blockages, the unblocking force can be reduced to avoid damage to the pipe caused by excessive force from the pointed cone. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] The purpose of this utility model is to provide a pipe unblocking device to solve the problems existing in the prior art. It uses the impact force of the falling hammer block to unblock the blockage with the pointed cone of the unblocking rod, which has a good unblocking effect and is easy to operate.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] Please refer to the following: Figure 1 As shown, a pipe unblocking device is provided, including an unblocking rod and a counterweight block 2. The unblocking rod includes a sliding section 7, an extension section 5 for extending into the pipe to be unblocked, and a pointed cone section 4 for unblocking the blockage. The sliding section 7, the extension section 5, and the pointed cone section 4 are integrally formed or welded together. The tip of the pointed cone section 4 needs to be set away from the extension section 5. The counterweight block 2 needs to be a block structure with high density and weight. The counterweight block 2 has a sliding hole that matches the sliding section 7. The counterweight block 2 is slidably set on the sliding section 7 through the sliding hole. The extension section 5 has a first blocking part 6 for blocking the counterweight block 2 at one end near the sliding section 7. The first blocking part 6 can be the extension section 5 itself or a structure set on the extension section 5. When the extension section 5 itself acts as the blocking part, the cross-sectional area of the extension section 5 is larger than the cross-sectional area of the sliding hole. Here, the cross-sectional area refers to the area of the cross section perpendicular to the length direction of the extension section 5.
[0025] The unblocking principle of this device is as follows: Utilizing the characteristic that the weight block 2 can slide freely on the sliding section 7 of the unblocking rod, when unblocking, the extension section 5 of the unblocking rod is inserted into the pipe to be unblocked, and the pointed cone section 4 of the unblocking rod contacts the blockage position. Then, the weight block 2 is pulled up and released. Under the influence of its own weight, the weight block 2 falls and hits the first blocking part 6. The impact force is transmitted to the pointed cone section 4 through the extension section 5, so that the pointed cone section 4 inserts into the blockage position to achieve unblocking of the blockage position.
[0026] The sliding section 7 needs to be made of wear-resistant material, and the outer peripheral wall of the sliding section 7 needs to be smoothed to reduce friction with the counterweight 2. Alternatively, lubricating oil can be applied to reduce friction with the counterweight 2.
[0027] The cone section 4 can be made of high-strength alloy material, giving it excellent penetration ability and the ability to easily penetrate the blockage.
[0028] A second blocking part 1 is provided at the end of the sliding section 7 away from the extension section 5. The second blocking part 1 is used to prevent the counterweight block 2 from coming out and to ensure that the counterweight block 2 is always on the sliding section 7. The cross-sectional area of the second blocking part 1 needs to be larger than the cross-sectional area of the sliding hole of the counterweight block 2. The cross-sectional area here refers to the area of the cross section perpendicular to the length direction of the sliding section 7.
[0029] In this embodiment, both the first blocking part 6 and the second blocking part 1 are circular, and the corners of the outer peripheral walls of the first blocking part 6 and the second blocking part 1 are eliminated to avoid the risk of scratches. In other embodiments, if the risk of scratches is not considered, the first blocking part 6 and the second blocking part 1 can also be designed as square rings or other shapes, as long as they can provide the function of blocking the movement of the hammer block 2.
[0030] The first blocking part 6 and the second blocking part 1 are configured as follows: the first blocking part 6 is welded or integrally disposed on the extension section 5, and the second blocking part 1 is welded or integrally disposed on the sliding section 7. The welding or integral disposal method can ensure the fixing effect of the blocking part and improve the service life of the device. When welding, full welding should be used to further improve the fixing effect of the blocking part.
[0031] At least one handle 3 is provided on the outer peripheral wall of the counterweight block 2. The operator can conveniently control the movement of the counterweight block 2 on the sliding section 7 through the handle 3. That is, by providing the handle 3, the ease of operation of the device is further improved.
[0032] In this embodiment, two handles 3 are provided on the outer peripheral wall of the hammer block 2. The two handles 3 are symmetrically arranged, so that the operator can operate the hammer block 2 with both hands in a more effortless way, which can further improve the ease of operation of the device. Since the hammer block 2 needs to be operated with both hands, the pointed cone section 4 needs to be inserted into the blocking position a certain distance before the hammer block 2 is lowered, so as to initially stabilize the overall device and prevent the overall device from tilting during the falling of the hammer block 2.
[0033] An anti-slip part is provided at the end of the handle 3 away from the counterweight block 2. The anti-slip part can provide a certain blocking effect for holding the handle 3 to prevent the handle 3 from slipping out of the hand during the holding process.
[0034] In this embodiment, the anti-slip part is designed as a sphere, and the maximum cross-sectional area of the anti-slip part is greater than the cross-sectional area of the handle 3. The cross-sectional area here refers to the area of the cross section perpendicular to the length direction of the handle 3. In other embodiments, the anti-slip part can be set as a cylinder, plate, etc., as long as it can provide a blocking effect.
[0035] The handle 3 is cylindrical to avoid the problem of the edges and corners scratching the operator's hands.
[0036] In this embodiment, both the counterweight block 2 and the sliding section 7 are cylindrical, and the counterweight block 2 and the sliding section 7 are coaxially arranged; in other embodiments, the counterweight block 2 and the sliding section 7 may also be polygonal cylinders.
[0037] In this embodiment, the extension segment 5 is cylindrical, and the end face of the conical segment 4 near the extension segment 5 matches the extension segment 5; in other embodiments, the extension segment 5 can be a polygonal column, while ensuring that the end face of the conical segment 4 near the extension segment 5 matches the extension segment 5, that is, the conical segment 4 is a cone structure with a polygonal base.
[0038] This device is suitable for straight pipes as well as curved pipes that can ensure the cone section 4 reaches the blockage position.
[0039] When applied to a straight pipe, a circular ring structure can be welded on the outer wall of the extension section 5 as a straightening ring. The outer diameter of the straightening ring is not greater than the inner diameter of the pipe. During the unblocking process, the straightening ring can be placed inside the pipe to ensure that the entire device will not be tilted at a large angle to the pipe during unblocking, and to ensure that the cone section 4 is directly facing the blockage location.
[0040] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
[0041] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
