Description

Technical Field

[0001] The present application relates to the technical field of ground wire installation, and in particular to a joint assembly, a traction auxiliary device and a traction system. Background Art

[0002] Generally, in the installation standards of power systems such as overhead lines, it is necessary to install ground wires to enhance the stability of the power system. At the same time, it is also necessary to replace the ground wires regularly to ensure the continued stability of the power system.

[0003] The removal and installation of the ground wire usually requires the power system to be powered off and then the new ground wire is manually released to the preset position. However, due to the heavy weight of the ground wire coil, a lot of manpower is required.

[0004] In the related art, in order to save manpower loss, some manufacturers use a traction machine and a traction rope to pull the ground wire, so that the ground wire can be placed in a preset position without manual pulling. However, in actual use scenarios, there are the following problems: On the one hand, the ground wire itself is twisted when placed, and the ground wire is difficult to pull.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0034] The present application provides a traction system, including a traction auxiliary device, a traction machine and a traction rope. The traction machine is used to drive the extension of the traction rope, and the traction rope is connected to the traction auxiliary device, so that the traction machine pulls the traction auxiliary device through the extension of the traction rope.

[0035] like Figure 1 As shown, the traction auxiliary device includes a joint assembly 100. Specifically, the joint assembly 100 includes a joint assembly 110 and an elastic sleeve assembly 120. The joint assembly 110 is provided with a first end 110a and a second end 110b. The first end 110a is used to connect and cooperate with the ground wire 20, and the second end 110b is used to connect and cooperate with the traction rope. The elastic sleeve assembly 120 is provided with an installation cavity. The ground wire 20 is limitedly inserted in the installation cavity so that the inner side wall of the installation cavity is abutted and matched with the outer side wall of the ground wire 20. The elastic sleeve assembly 120 is connected to the joint assembly 110 (such as the elastic sleeve assembly 120 can be connected to the first end 110a), so that the elastic sleeve assembly 120 can be extended and retracted along the length direction of the elastic sleeve assembly 120 under the tensile force of the joint assembly 110, driving the elastic sleeve assembly 120 to expand or contract along the radial direction of the elastic sleeve body.

[0036] The following is a detailed description of the use of the connector assembly 100 in conjunction with an implementation scenario:

[0037] First, the elastic sleeve assembly 120 is sleeved on the ground wire 20, and the ground wire 20 and the elastic sleeve assembly 120 are limitedly matched. Then, one end of the elastic sleeve assembly 120 is connected to the first end 110a, and the ground wire 20 is also connected to the first end 110a, so that the elastic sleeve assembly 120 and the ground wire 20 are connected to the joint assembly 100. Accordingly, the traction rope is connected to the second end 110b, and the preparation before traction is completed.

[0038] By driving the traction machine to wind and drive the traction rope to move, the traction rope pulls the ground wire 20 and the elastic sleeve assembly 120 through the pulling joint assembly 100, thereby pulling the ground wire 20 to the preset installation position and completing the installation of the ground wire 20.

[0039] It can be understood that the elastic sleeve assembly 120 is sleeved on the ground wire 20 so that the inner wall of the elastic sleeve assembly 120 abuts against the outer wall of the ground wire 20 . When the traction machine drives the traction rope to be deployed, the traction rope has a pulling force on the joint assembly 100, that is, the first end 110a has a motion vector in the movement direction of the traction rope (hereinafter referred to as the first direction), and then one end of the elastic sleeve assembly 120 is subjected to the pulling force of the first end 110a along the first direction, and the other end is subjected to the pulling force of the ground wire 20 along the second direction opposite to the first direction (including the resistance of the ground wire 20 to the elastic sleeve assembly 120), so that the two ends of the elastic sleeve assembly 120 are pulled in different directions, and the increase in the length of the elastic sleeve assembly 120 drives the elastic sleeve assembly 120 to be compressed in the radial direction, so that the elastic sleeve assembly 120 can press and flatten the ground wire 20, avoiding the accident of the ground wire 20 being twisted due to excessive tension or uneven tension during the traction process of the traction rope to the joint assembly 100 and the ground wire 20, ensuring that the ground wire 20 can be pulled smoothly, and improving the efficiency and quality of the replacement of the ground wire 20.

[0040] It should be noted that the length of the elastic sleeve assembly 120 is not limited and can be designed and selected according to actual needs.

[0041] In some embodiments, the elastic sleeve assembly 120 is sleeved on a portion of the ground wire 20. It is understandable that during the traction process of the traction rope joint assembly 100 and the ground wire 20, when the tension is too large or the force is uneven, the portion of the ground wire 20 close to the traction end (i.e., the first end 110a) is twisted. Based on this, the elastic sleeve assembly 120 can be sleeved on the ground wire 20 to achieve targeted compression of the portion of the ground wire 20 to prevent it from rotating and twisting. At the same time, the processing distance of the elastic sleeve assembly 120 in the length direction can be saved, thereby reducing the processing difficulty and improving the efficiency of disassembly and assembly of the ground wire 20.

[0042] It should be noted that the connection between the first end 110a and the ground wire 20, and the connection between the second end 110b and the traction rope can be, but not limited to, a snap connection, a plug-in connection, etc., and no excessive restrictions are imposed here.

[0043] In some embodiments, Figure 2As shown, the first end 110a and the second end 110b are both provided with a first plug-in portion 110c (such as a socket), and the ground wire 20 is provided with a second socket. The connector assembly 100 also includes a plug assembly 130, and the plug assembly 130 includes a first plug 131 and a second plug 132. The first plug 131 is inserted in the first plug-in portion 110c and the second socket, so that the ground wire 20 is connected to the first end 110a. In this way, the ground wire 20 is plugged and fixed by the first plug 131, so that the ground wire 20 is synchronously driven to move through the connector assembly 100, which is conducive to the disassembly of the ground wire 20 and has a good fixing effect. Further, different from the buckle connection, the setting of the first plug 131 reduces the processing of the ground wire 20, and only needs to process and form the second socket at one end of the ground wire 20, and the strength of the ground wire 20 itself can be used to improve the connection strength between the ground wire 20 and the first end 110a, and avoid the traction and separation of the ground wire 20 and the first end 110a.

[0044] Similarly, in another example, the traction rope is provided with a third plug hole, and the second plug pin 132 is inserted between the third plug hole and the first plug portion 110c, so that the traction rope is connected to the second end 110b. In this way, the traction rope is fixed by plugging the second plug pin 132, which is beneficial to improving the fixing effect of the traction rope and reducing the processing of the traction rope, which is beneficial to improving the processing efficiency.

[0045] Further, in one embodiment, Figure 2 , at least one of the first end 110a and the second end 110b is provided with a slot 110d. At least one of the ground wire 20 and the traction rope is limitedly inserted in the slot 110d. The slot 110d can be connected to the third socket or the second socket. It can be understood that after the ground wire 20 or the traction rope is inserted into the slot 110d, the pin assembly 130 is inserted into the corresponding socket to achieve the fixation of the two. In this way, the installation efficiency of the ground wire 20 or the traction rope can be improved, and the matching area between the ground wire 20 or the traction rope and the joint assembly 110 is increased, thereby improving the fixing effect of the two.

[0046] In addition, in one example, a first introduction portion is provided at one end of the ground wire 20. In the direction from the second end 110b to the first end 110a, the first introduction portion is gradually gathered, and the ground wire 20 is introduced and inserted into the plug-in portion through the first introduction portion. In another example, a second introduction portion is provided at one end of the traction rope. In the direction from the first end 110a to the second end 110b, the second introduction portion is gradually gathered, and the traction rope is introduced and inserted into the plug-in portion through the second introduction portion.

[0047] In this way, through the setting of the first introduction part and / or the second introduction part, when the ground wire 20 or the traction rope is plugged into the plug-in part, an interference fit between the ground wire 20 or the traction rope and the plug-in part can be achieved, thereby improving the connection strength between the ground wire 20 or the traction rope and the plug-in part. The inner side wall of the plug-in part can form a good friction abutment with the ground wire 20 or the traction rope, thereby avoiding the separation of the ground wire 20 or the traction rope from each other, and ensuring stability during the traction process.

[0048] It should be noted that the elastic sleeve assembly 120 can be, but is not limited to, a soft columnar structure, and can also be a mesh structure, etc., and no further limitations are given here.

[0049] In combination with any of the above embodiments of the elastic sleeve assembly 120, Figure 3 As shown, the elastic sleeve assembly 120 includes a sleeve 121 and an elastic net 122. The sleeve 121 is provided with a mounting cavity. The elastic net 122 is limitedly sleeved outside the sleeve 121. The elastic net 122 is connected to the joint assembly 110, so that the joint assembly 110 and the elastic net 122 are pulled together to drive the elastic net 122 to expand or retract in the radial direction, so that the elastic net 122 and the sleeve 121 are pressed together.

[0050] That is, a layer-by-layer wrapping structure of the ground wire 20, the sleeve 121 and the elastic net 122 is formed. It can be understood that when the pulling force of the joint assembly 100 on the ground wire 20 is 0 or small, the sleeve 121 limits the pressure on the ground wire 20 to ensure that the ground wire 20 is straight before or in the initial stage of pulling to avoid rotation. When the pulling force of the joint assembly 100 on the ground wire 20 is large, the elastic net 122 is stretched in the length direction, so that the elastic net 122 shrinks in the radial direction, and then the elastic sleeve clamps the sleeve 121 to achieve the pressure of the sleeve 121 on the ground wire 20, effectively preventing the ground wire 20 from being twisted due to excessive or uneven pulling force, and ensuring the pulling effect of the ground wire 20.

[0051] In addition, the structure of the elastic net 122 adopted in this embodiment, which is different from the hollow column structure, avoids the influence of the extension distance on the connection strength limitation of the elastic sleeve assembly 120 itself, thereby ensuring the stretching range of the elastic net 122, thereby improving the compression range of the ground wire 20 and enriching the use scenarios of the compression of the ground wire 20.

[0052] The elastic net 122 may be a metal wire net or a plastic tough material (such as stretchable rubber, etc.).

[0053] Further, in one example, see Figure 3The elastic sleeve assembly 120 further includes a fastener. The fastener is disposed at one end of the elastic net 122 and cooperates with the latch to connect the elastic net 122 to the first end 110a. In this way, the length of the elastic net 122 can be minimized to save costs. The elastic net 122 and the ground wire 20 can be fixed integrally by the latch, thereby improving the installation efficiency of the ground wire 20.

[0054] In combination with any of the above embodiments of the connector assembly 110, Figure 2 The connector assembly 110 includes a first connector 111, a second connector 112, and a connector assembly 113. The connector assembly 113 is connected between the first connector 111 and the second connector 112. The first connector 111 is provided with a first end 110a. The second connector 112 is provided with a second end 110b.

[0055] In one specific embodiment, in combination Figure 4 as well as Figure 5 As shown, the connection assembly 113 includes a pressure detection member 1131, a first rotating shaft 1132 and a battery element 1133. One end of the first rotating shaft 1132 is connected to the first connector 111, and the other end is connected to the pressure detection member 1131, so that the first connector 111 is fixed to the pressure detection member 1131 through the first rotating shaft 1132. The connection between the first rotating shaft 1132 and the pressure detection member 1131 can be a snap connection, plug-in connection, etc. The pressure detection member 1131 is provided with a feeding part, which is used to be electrically connected to the battery element 1133, so that the pressure detection member 1131 can detect the pulling force value of the first rotating shaft 1132 on the first connector 111.

[0056] In this way, the acquisition of the tension value can facilitate the operator to judge the tension of the traction rope on the ground wire 20 at this time through the tension value. When the tension is too large, it can be adjusted in time to avoid the equipment falling off and the overhead ground wire 20 being pulled too tight due to excessive tension, thereby improving the safety of the ground wire 20 traction operation.

[0057] It should be noted that the type of pressure detection element 1131 can be to detect tension by obtaining elastic deformation (such as judging the tension by measuring the elastic deformation), or to judge the tension value by measuring the change in resistance value caused by the change in elastic force.

[0058] In one example, the pressure detection member 1131 includes a first connecting member, a second connecting member, an elastic connecting member and an optical sensor element. The elastic connecting member is connected between the first connecting member and the second connecting member, the first connecting member is connected and matched with the first rotating shaft 1132, and the second connecting member is connected and matched with the second rotating shaft. The optical sensor element is used to detect the elastic length of the elastic connecting member, so that the tension value can be obtained according to the elastic length. In this way, the pressure detection member 1131 of this design has a simple structure and is easy to process. Furthermore, elastic connecting members such as springs, stretching rubbers, etc. can form a certain buffer during the pulling process of the joint assembly 100, reduce the collision of the joint assembly 100 during the pulling process, and ensure the service life of the joint assembly 100.

[0059] In another example, the pressure detection element 1131 includes a stress sensing element and a battery element 1133. The stress sensing element is provided with a power feeding portion. The battery element 1133 is connected to the power feeding portion for power feeding, so that the stress sensing element is powered to detect the tension value.

[0060] Thus, by setting the stress sensing element, on the one hand, the stress sensing element can be used as a connecting piece between the first rotating shaft 1132 and the second rotating shaft, that is, as a connecting piece between the first joint and the second joint, so as to improve the structural strength between the first rotating shaft 1132 and the second rotating shaft. On the other hand, different from detecting pressure changes by elastic length changes, the elastic changes between the surfaces of the stress sensing element are used to detect resistance values ​​and are used to detect pressure. It is convenient and easy to obtain and process. At the same time, the pressure sensing element will not be elastically twisted, thereby avoiding the torsional elastic force affecting the detection accuracy of the pulling force, and also avoiding the difficulty of pulling caused by the twisting of the joint assembly 100, which is conducive to improving the pulling efficiency and quality, and saving more effort.

[0061] The tension value detected by the pressure sensor may be transmitted to an external device via a wired or wireless connection, or may be transmitted through a built-in control element and an alarm element, so that the control element determines whether the tension value exceeds a preset standard, thereby triggering the alarm element to sound an alarm, etc. The alarm element may be a warning light, a warning bell, or any combination thereof, and no excessive restrictions are imposed herein.

[0062] Further, see you later Figures 4 to 5 The connector assembly 100 further includes a wireless communication module 140. The wireless communication module 140 is disposed in the connection assembly 113 and is communicatively connected with the pressure detection member 1131 and an external device, so that the wireless communication module 140 transmits the tension value to the external device.

[0063] It is understandable that the installation of the ground wire 20 generally needs to be carried out at high altitudes with large spacing distances. Therefore, by electrically connecting the wireless module with external equipment, it is possible to monitor the changes in the tension value in real time, which is conducive to timely adjusting the tension of the traction machine, ensuring that the tension is not too large, and improving the stability of the pulling process of the ground wire 20.

[0064] It should be noted that the wireless module can be but not limited to WiFi, Bluetooth, Zigbee, etc., and no excessive restrictions are made here.

[0065] In addition, in order to improve the transmission quality and efficiency of the wireless module, in other embodiments, Figures 4 to 5 , the connection assembly 113 further includes an insulating housing 1134. At least part of the insulating housing 1134 is sleeved on the battery element 1133, so that at least part of the battery element 1133 is insulated and matched with the wireless communication module 140 through the insulating housing 1134. In this way, by setting the insulating housing 1134 between at least part of the battery element 1133 and the wireless communication module 140, at least part of the electromagnetic signal of the battery element 1133 will be shielded by the insulating housing 1134, ensuring the normal transmission of the signal of the wireless communication module 140, and preventing the battery element 1133 from causing electrical signal interference to the wireless communication module 140.

[0066] Further, see Figure 5 The connection assembly 113 further includes a connection bearing 1135, which is disposed in contact with a side of the pressure detection member 1131 away from the first connector 111. One end of the insulating housing 1134 is connected and matched with the second connector 112. Specifically, one of the pressure detection member 1131 and the insulating housing 1134 is provided with a slide groove 1131c, and the other is provided with a plug-in connector 1134c. The relative sliding of the pressure detection member 1131 and the insulating housing 1134 is achieved through the sliding cooperation between the plug-in connector 1134c and the slide groove 1131c.

[0067] In this way, when the pulling force of the traction rope on the ground wire 20 is large or unevenly distributed, resulting in a certain degree of distortion of the ground wire 20, the difference in movement speed between the first connector 111 and the second connector 112, as well as the sliding cooperation between the convex portion 113a and the slide groove 1131c, can increase the buffer distance of the ground wire 20, which is conducive to the reset of the ground wire 20 based on its own elasticity, and further improves the effect of keeping the ground wire 20 straight. In one example, the insulating housing 1134 is plugged and matched with the second connector, which can save the length of the connector assembly 100 in the length direction, and facilitate the miniaturization of the connector assembly 100.

[0068] In addition, in other embodiments, see Figures 4 to 5, the insulating shell 1134 can also be set on the battery element 1133. Among them, the insulating shell 1134 is provided with a non-insulating area 1134a and an insulating area 1134a arranged around the non-insulating area 1134a, and the insulating area 1134a is arranged opposite to the battery element 1133, so that the battery element 1133 is insulated and matched with the wireless module through the insulating area 1134a. The non-insulating area 1134a is arranged opposite to the wireless module, so that the electromagnetic signal of the wireless module can be emitted through the non-insulating area 1134a. In this way, the centralized emission of electromagnetic signal transmission of the wireless module can be realized, thereby improving the signal transmission efficiency between the wireless module and the external device.

[0069] In one specific embodiment, the insulating housing 1134 is provided with a hollow portion, and the non-insulating area 1134a is provided on the hollow portion. In this way, the hollow portion is directly used as the non-insulating area 1134a, which is simple in design and convenient for processing.

[0070] In another embodiment, Figure 2 The connection component 113 further includes a signal gain component 150, which is arranged corresponding to the wireless communication module 140 to gain the electromagnetic signal of the wireless communication module 140. Gaining the electromagnetic signal of the wireless communication module 140 refers to increasing the transmission range (such as transmission distance) of the electromagnetic signal, or increasing the strength of the electromagnetic signal (i.e., amplifying the electromagnetic signal), or any one or a combination of multiple factors.

[0071] In this way, the signal transmission quality of the wireless module can be improved to increase the signal interaction speed between the wireless module and the external device, thereby facilitating timely adjustment of the traction machine and avoiding the use of high pulling force for too long a time.

[0072] In one example, the signal gain component 150 is set corresponding to the non-insulating area 1134a in the above embodiment to gain the electromagnetic signal of the wireless transmission module. In this way, the corresponding setting of the signal gain component 150 and the non-insulating area 1134a does not require additional installation positions of the signal gain component 150 in the length direction, which is beneficial to reducing the length direction of the connector assembly 100 and reducing the processing steps. Among them, the corresponding setting of the signal gain component 150 in the non-insulating area 1134a can be a sliding connection, or it can be a connection method such as bonding or clamping.

[0073] It should be noted that the signal gain component 150 can be a metal connecting component such as a copper sheet, a metal patch antenna, etc., and no excessive restrictions are made here.

[0074] In combination with any of the above-mentioned embodiments of the first rotating shaft 1132, the connecting assembly 113 further includes a ball bearing and a second rotating shaft, and the second rotating shaft is connected to the second connector 112. One of the first rotating shaft 1132 and the second rotating shaft is sleeved on the outer ring of the ball bearing, and the other is inserted in the inner ring of the ball bearing in a limited position. In one example, the first rotating shaft 1132 is inserted in a limited position with the inner ring of the ball bearing, and the second rotating shaft is sleeved on the outer ring of the ball bearing.

[0075] It is understandable that when the pulling force is too large or uneven, the first rotating shaft 1132 may be twisted relative to the second rotating shaft. At this time, the second rotating shaft will not rotate in the axial direction with the first rotating shaft 1132 by setting the ball bearing, thereby reducing the resistance of the traction rope to pull the ground wire 20, thereby improving the pulling efficiency of the ground wire 20. Furthermore, the relative rotation posture of the first rotating shaft 1132 or the second rotating shaft can be adjusted by rotating the ball bearing, so that the first rotating shaft 1132 and the second rotating shaft can be relatively kept straight, ensuring that the first rotating shaft 1132 and the second rotating shaft can be pulled normally.

[0076] In combination with any of the above-mentioned embodiments of the first rotating shaft 1132, Figure 4 as well as Figure 5 , the connecting assembly 113 also includes a thrust bearing 1136. In one specific embodiment, the thrust bearing 1136 is inserted into the first rotating shaft 1132, and is abutted between the first joint and the pressure detection member 1131. In another specific embodiment, the thrust bearing 1136 is inserted into the first rotating shaft 1132, and the thrust bearing 1136 is abutted against the pressure detection member 1131. In this way, by inserting the thrust bearing 1136 into the first rotating shaft 1132 and abutting against any one side of the pressure detection member 1131, the first rotating shaft 1132 will not drive the second connector 112 to rotate axially through the pressure detection member 1131, thereby avoiding the traction rope from being driven to transmit when the ground wire 20 is twisted, and ensuring the traction stability between the traction machine and the traction rope. Accordingly, when the traction rope is twisted, the traction rope will not drive the first rotating shaft 1132 to rotate through the pressure detection member 1131, thereby ensuring that the pulling of the ground wire 20 is stable, thereby ensuring that the ground wire 20 remains straight when pulled to the preset installation position.

[0077] In combination with any embodiment of the traction assist device 10, Figure 6 to Figure 7As shown, the traction auxiliary device 10 also includes a mobile pulley 200, and the mobile pulley 200 includes a support assembly 210, a fixed bracket 220 and a roller 230. The support assembly 210 is used to install the ground wire 20, one end of the fixed bracket 220 is connected to the support assembly 210, and the other end is connected to the roller 230 in a rolling manner. The ground wire 20 can drive the support assembly 210 to move synchronously, so that the ground wire 20 drives the roller 230 to roll relative to the ground. It can be understood that the support assembly 210 and the ground wire 20 remain relatively fixed. When the traction rope pulls the ground wire 20, it will drive the ground wire 20 to pull the support assembly 210 to move, and at this time, the roller 230 rolls with the ground. In this way, the movement resistance of the ground wire 20 when moving on the ground can be reduced, which is conducive to avoiding wear on the ground wire 20 and ensuring the performance of the ground wire 20.

[0078] Furthermore, if Figure 7 As shown, the support assembly 210 includes a support frame 211 and hanging arms 212 arranged at intervals on both sides of the support frame 211. The support frame 211 can be rotatably arranged at one end of the support assembly 210, and the ground wire 20 is installed on the hanging arms 212 on both sides of the support frame 211. In this way, by installing the ground wire 20 to the hanging arms 212 on both sides of the support frame 211, the ground wire 20 has at least two fixed positions on the mobile pulley 200, which is conducive to improving the movement stability of the ground wire 20 on the mobile pulley 200. Further, the support frame 211 can be rotatably arranged at one end of the support assembly 210, so that the support frame 211 is equivalent to a lever. When the tension is too large or too small, it will cause the support frame 211 to swing, so as to achieve the ground wire 20 on the corresponding side being tightened during the swinging process, ensuring the straightness of the ground wire 20, and then improving the traction efficiency of the ground wire 20.
