Description

Technical Field

[0001] This utility model relates to the field of power construction equipment technology, and in particular to a power construction traction component. Background Technology

[0002] In the field of power construction, traction components are crucial equipment used to pull heavy objects such as cables and equipment to complete tasks such as line laying and equipment installation. With the continuous expansion of power engineering projects and the increasing complexity of construction environments, the performance requirements for traction components are also rising. Whether it's the upgrading and transformation of urban power grids or the construction of power facilities in remote areas, traction components must operate stably, efficiently, and safely to ensure the smooth progress of the entire power construction project, reduce construction delays, safety accidents, and equipment damage caused by problems in the traction process, and thus guarantee the rapid construction and reliable operation of the power supply network.

[0003] Traditional power construction traction components mainly consist of a traction machine and a traction rope. The traction machine provides traction power, which drives the traction rope through a drum. During traction operations, the traction rope passes around the drum, and the pulled object moves due to the tension of the traction machine. Throughout the process, the relationship between the drum and the traction rope is relatively fixed, lacking an adaptive adjustment mechanism for changes in the tension of the traction rope. Furthermore, the connections between the traction rope and other components are usually fixed with bolts and nuts or complex snap-fit ​​structures, requiring multiple tools and steps for installation.

[0004] However, the traditional structure suffers from the problem that ordinary steering pulleys cannot adaptively adjust according to the tension of the traction rope. When the tension of the traction rope changes significantly, such as when pulling a heavy object or encountering sudden resistance, slippage is very likely to occur between the drum and the traction rope. This slippage not only reduces traction efficiency, causing the traction operation to fail as expected, but also causes excessive wear of the traction rope due to uneven friction. In severe cases, it can even cause the traction rope to break, leading to safety accidents, endangering the lives of construction workers, as well as the facilities and environment around the construction site. This greatly affects the stability and safety of power construction and increases construction costs and time costs. Therefore, a power construction traction component is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figure 1 - Figure 4This utility model provides an embodiment of a power construction traction assembly, including a base plate 1. The base plate 1 serves as the basic support for the entire traction assembly and is made of high-strength alloy steel, possessing good compressive strength and stability. It can stably support other components and ensure structural integrity under various complex construction environments. A support arm 2 is fixedly connected to the top of the base plate 1. The support arm 2 is made of metal and has undergone rust prevention treatment. It mainly provides a stable installation position and support force for the power assembly and the adjustment assembly. The support arms 2 are symmetrically distributed on the top of the base plate 1. A power assembly is provided on the side wall of the support arm 2. The power assembly is used to provide traction power for traction operations. An adjustment assembly is provided between the support arms 2. The adjustment assembly is used to adjust the traction drum. The position is adjusted; the adjustment component includes an inner drum 4, the main body of which is made of metal. Multiple connecting springs 9, made of high-quality spring steel, are installed on the outer wall of the inner drum 4, possessing good elasticity and fatigue resistance. One end of each spring 9 is fixedly connected to the outer wall of the inner drum 4 by welding, and the other end is fixedly connected to an outer drum 5 in the same manner. The connecting springs 9 are arranged in a circumferential array on the outer wall of the inner drum 4. One end of each connecting spring 9 is fixedly connected to the outer wall of the inner drum 4, and the other end is fixedly connected to the outer drum 5. The outer drum 5 is made of the same material as the inner drum 4. During traction, both springs cooperate to contact the traction line 6 and achieve traction. A fixed disk 11 is fixedly connected to the inner wall of the inner drum 4, and a rotating disk 14 is rotatably connected to the side wall of the fixed disk 11. Multiple grooves 15 are provided on the side wall of the rotating disk 14. The grooves 15 are distributed in a circumferential shape on the side wall of the rotating disk 14. Limiting rods 13 are slidably connected to the inner wall of the grooves 15. One end of the limiting rod 13 is fixedly connected to a telescopic column 12. The two are connected by welding. The telescopic column 12 is slidably connected inside the fixed disk 11. The telescopic column 12 is made of metal and has a smooth outer wall. It is slidably connected in a pre-set sliding hole inside the fixed disk 11. An internal gear 16 is fixedly connected to the inner wall of the rotating disk 14. A second drive motor 18 is fixedly connected inside the inner drum 4. A drive gear 17 is fixedly connected to the output end of the second drive motor 18. The drive gear 17 meshes with the internal gear 16. The power assembly includes a first drive motor 7. The bottom of the first drive motor 7 is fixedly connected by bolts. The drive motor 7 is fixedly connected to the side wall of the support arm 2. It has stable power output performance and high efficiency. Its output end is fixed to the transmission shaft 8 through a coupling. The bottom of the drive motor 7 is fixedly connected to the side wall of the support arm 2. The output end of the drive motor 7 is fixedly connected to the transmission shaft 8. The transmission shaft 8 is made of high-strength carbon steel. Its outer wall is connected to the inside of the inner drum 4 through a key connection. The outer wall of the transmission shaft 8 is fixedly connected to the inside of the inner drum 4. Multiple support plates 3 are fixedly connected to one side of the top of the base plate 1. The support plates 3 are symmetrically distributed on the top of the base plate 1. The outer wall of the outer drum 5 is provided with a wheel groove 10. The inner wall of the wheel groove 10 is made of rubber, which can increase the friction with the traction line 6 and reduce the wear of the traction line 6. The traction line 6 is slidably connected to the inner wall of the wheel groove 10.

[0035] Specifically, during the traction process, the drive motor 7 rotates, causing the transmission shaft 8, which is fixedly connected to it, to rotate synchronously. The transmission shaft 8 then drives the inner drum 4, which is connected to it via a key, to rotate. Since the outer drum 5 is connected to the inner drum 4 via a connecting spring 9, when the tension of the traction line 6 is small, the connecting spring 9 is in its natural state or only slightly compressed. At this time, the relative position between the inner drum 4 and the outer drum 5 remains basically stable, and no significant relative displacement occurs. The rubber part in the groove 10 on the outer wall of the outer drum 5 maintains its normal shape because it is not subjected to a large external force, and the traction line 6 can run smoothly forward along the tangential direction of the outer drum 5 within the groove 10. When the tension of the traction line 6 gradually increases, the outward pulling force on the outer drum 5 increases, and part of the connecting spring 9 begins to be stretched, causing the outer drum 5 to displace radially outward relative to the inner drum 4. When the tension exceeds the set threshold, the drive motor 18 inside the inner drum 4 starts, and its output drives the drive gear 17 to rotate. The drive gear 17 meshes with the inner gear 16, causing the inner gear 16 and the rotating disk 14 fixedly connected to it to rotate. The rotation of the rotating disk 14 causes multiple sliding grooves 15 inside it to rotate synchronously. Since the limiting rod 13 is slidably connected to the inner wall of the sliding groove 15, during the rotation of the sliding groove 15, the limiting rod 13 is pushed by the inner wall of the sliding groove 15 and displaced radially outward, thereby causing the telescopic column 12 fixedly connected to it to extend outward. The telescopic column 12 slides outward along the sliding hole inside the fixed disk 11 and finally inserts into the corresponding hole of the outer drum 5, thereby limiting the further separation of the inner drum 4 and the outer drum 5, thus realizing the function of automatically adjusting the engagement state of the hub and the traction line 6 according to the tension of the traction line 6.

[0036] Reference Figure 5One end of the traction line 6 is fixedly connected to a connector 21. The connector 21 serves as the connection point between the traction line 6 and other components. Its shape is designed to facilitate connection with the fixing seat 19, and it possesses good mechanical strength to withstand the tension during the traction process. The outer wall of the connector 21 is provided with a fixing seat 19, which serves as the receiving and fixing component of the connector 21. It is made of metal and has undergone anti-corrosion treatment. A hook 20 is fixedly connected to the side wall of the fixing seat 19. The hook 20 is a curved component made of metal and is used to connect with the object being pulled in order to transmit traction power. A connecting pin 22 is slidably connected to the inner wall of the fixing seat 19. The connecting pin 22 is made of metal. Made of high-strength metal material, the top of the connector is fixedly connected to a rotating rod 23 by welding. The top of the connecting pin 22 is fixedly connected to the rotating rod 23. The rotating rod 23 is a cylindrical metal rod, which is convenient for manual operation by construction personnel. The bottom of the connecting pin 22 is fixedly connected to a connecting post 25. A limiting spring 24 is sleeved on the outer wall of the connecting post 25. One end of the limiting spring 24 is fixedly connected to the bottom of the connecting pin 22, and the other end of the limiting spring 24 is fixedly connected to the inner wall of the fixing seat 19. The bottom of the connecting post 25 is fixedly connected to a limiting post 26. The limiting post 26 is slidably connected to the inner wall of the fixing seat 19 and moves in the guide groove preset in the inner wall of the fixing seat 19 to limit and fix the connector 21.

[0037] Specifically, when using this traction device in power construction, when the traction line 6 needs to be installed, the connector 21 at the end of the traction line 6 is first made into a flat shape using machining equipment, and a through hole is machined at a specific position. Then, the connector 21 is inserted into the interior of the fixed base 19 along the inlet direction. At this time, the construction worker holds the rotating rod 23 and presses it down vertically downward to the bottom position. During this process, the rotating rod 23 drives the connecting pin 22, which is fixedly connected to it, to move synchronously in the vertical downward direction. At the same time, the connecting pin 22 begins to rotate around its own axis. The downward movement of the connecting pin 22 causes the connecting post 25 welded to it to also move vertically downward. During the downward movement of the connecting post 25, the limiting spring sleeved on its outer wall... When the 24 is compressed, the limiting post 26 on the side wall of the connecting post 25 first passes through the through hole of the connector 21 in the vertical direction. As the connecting post 25 continues to move downward, when the limiting post 26 is removed from the obstruction below the through hole of the connector 21, due to the rotation of the connecting pin 22, the connecting post 25 drives the limiting post 26 to rotate a certain angle along the guide groove direction of the inner wall of the fixing seat 19, so that the limiting post 26 extends into the interior of the fixing seat 19 and is locked into the corresponding slot position, thereby realizing the reliable connection between the traction line 6 and the fixing seat 19, thus achieving the effect of fast and efficient installation of the traction line 6.

[0038] Working principle: When using this traction device in power construction, when the traction line 6 needs to be installed, firstly, the connector 21 at the end of the traction line 6 is made into a flat shape and a through hole is machined. Then, the connector 21 is inserted into the fixed seat 19. At this time, the construction personnel first press down the rotating rod 23 to the bottom and then rotate the rotating rod 23. During the screwing process, the rotating rod 23 drives the connecting pin 22 to rotate and move downward. The connecting pin 22 drives the connecting post 25 to move downward as well, so that the limiting post 26 on the side wall of the connecting post 25 first passes through the through hole of the connector 21, and then extends into the fixed seat 19 and rotates, thereby realizing a reliable connection between the traction line 6 and the fixed seat 19, thus achieving the effect of fast and efficient installation of the traction line 6. During the traction process, the drive motor 7 drives the transmission shaft 8 to rotate, driving the inner drum 4 and the outer drum 5 to perform traction work on the traction line 6. When the tension of the traction line 6 is small, the connecting spring 9 is in a self-sustaining state. In the normal or slightly compressed state, the inner drum 4 and outer drum 5 remain relatively stationary, the rubber part of the wheel groove 10 maintains its normal shape, and the traction line 6 runs smoothly within the wheel groove 10. When the tension of the traction line 6 gradually increases, the outward pulling force on the outer drum 5 increases, and part of the connecting spring 9 is stretched. The relative positions of the outer drum 5 and inner drum 4 are displaced. When the tension exceeds the set threshold, the drive motor 18 drives the drive gear 17 to rotate. The rotation of the drive gear 17 causes the rotating disk 14 to rotate. The rotation of the drive gear 17 causes the multiple sliding grooves 15 inside it to also move. The displacement of the sliding grooves 15 causes the limiting rod 13 to also move, thereby causing the telescopic column 12 to extend outward and insert into the corresponding hole of the outer drum 5, thus limiting the further separation of the inner drum 4 and outer drum 5. This achieves the effect of automatically adjusting the engagement state of the wheel hub and the traction line 6 according to the tension of the traction line 6.
