Description

Technical Field

[0001] This application relates to the technical field of wire preparation and application, and particularly to a wire pretreatment device. Background Art

[0002] The wire can be a metal wire, and the wire is used for transmitting electricity.

[0003] The wire is erected through a pole tower. The wire between two adjacent pole towers will sag and deform due to gravity. The deformation includes elastic deformation and plastic deformation. Among them, the plastic deformation is irreversible. After the plastic deformation, the length of the wire between the adjacent pole towers will increase, and the increased length is the initial elongation of the wire. The initial elongation causes the sag of the wire to increase. As a result, the distance between the wire and the ground and between the wire and other objects decreases, not meeting the requirement of the safety distance. In the related art, when erecting the wire, the installation sag can be reduced so that when the wire generates initial elongation during operation, the increased sag can compensate for the reduced installation sag during wire erection. It is also possible to reduce the temperature when erecting the wire to reduce the initial elongation of the wire according to the temperature compensation method.

[0004] In the related art, the method of reducing the initial elongation of the wire will increase the difficulty of the wire erection construction process. Summary of the Utility Model

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present application belong to the scope of protection of the present application.

[0048] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, or an indirect connection through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0049] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0050] The terms "first", "second", "third" (if any) in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0051] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or maintenance tool comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or maintenance tools.

[0052] The wire can be a metal wire, and the wire is used to transmit electricity.

[0053] The wire is erected through poles and towers. The wire between two adjacent poles and towers will sag and deform due to gravity. The deformation includes elastic deformation and plastic deformation. Among them, the plastic deformation is irreversible. After the plastic deformation, the length of the wire between adjacent poles and towers will increase, and the increased length is the initial elongation of the wire. The initial elongation causes the sag of the wire to increase. As a result, the distance between the wire and the ground and between the wire and other objects decreases, not meeting the requirement of the safety distance.

[0054] In the related art, during the wire stringing construction, the installation sag of the wire is appropriately reduced. Thus, when the wire generates initial elongation during operation, the increased sag can compensate for the reduced installation sag during wire stringing, so as to meet the requirement of the safety distance. However, reducing the installation sag will increase the force on the poles and towers, and thus increase the difficulty of the construction process.

[0055] Increasing the stringing stress is equivalent to lowering the temperature during wire stringing. Therefore, the method of using the stress after lowering the wire stringing temperature as the stringing stress can be used for compensation, which is the temperature compensation method. However, the creep equations of different specifications of wires are different, the creep amounts are also different, and the required construction temperatures are also different, which is not convenient for the wire stringing construction.

[0056] In the related art, reducing the initial elongation of the wire is carried out during the wire stringing process, which will increase the difficulty of the wire stringing construction process.

[0057] Based on this, this application provides a wire pretreatment device, which can pretreat the wire before wire stringing, so as to reduce the initial elongation of the wire and facilitate the wire stringing construction.

[0058] Figure 1 It is a schematic structural diagram of the wire pretreatment device provided by the embodiment of this application; Figure 2Schematic diagram of the usage state of the wire pretreatment device provided by the embodiment of the present application Figure 1 。

[0059] See Figure 1 and Figure 2 As shown in FIGS. and, the wire pretreatment device 100 provided by the embodiment of the present application is used to reduce the initial elongation of the wire 200. The wire pretreatment device 100 includes a wire pay-off assembly 110, an initial elongation reduction assembly 120, and a wire take-up assembly 130. The wire pay-off assembly 110, the initial elongation reduction assembly 120, and the wire take-up assembly 130 are arranged in sequence along the traveling direction X of the wire 200. The initial elongation reduction assembly 120 includes a plurality of electric heating cylinders 121 arranged in sequence along the traveling direction X, and the preset temperatures of the plurality of electric heating cylinders 121 gradually increase first and then gradually decrease along the traveling direction X.

[0060] The wire pay-off assembly 110 includes a wire pay-off frame 111 and a wire pay-off reel 112, and the wire pay-off reel 112 is mounted on the wire pay-off frame 111; the wire take-up assembly 130 includes a wire take-up frame 131 and a wire take-up reel 132, and the wire take-up reel 132 is mounted on the wire take-up frame 131.

[0061] The wire pay-off frame 111 can be arranged on the ground, and the wire pay-off reel 112 is mounted by the wire pay-off frame 111 at a certain height. The wire pay-off reel 112 is used for winding the wire 200 to be processed. The wire take-up frame 131 can be arranged on the ground, and the wire take-up reel 132 is mounted by the wire take-up frame 131 at a certain height. The wire take-up reel 132 is used for winding the processed wire 200, and the direction from the wire pay-off reel 112 to the wire take-up reel 132 is the traveling direction X of the wire 200.

[0062] The initial elongation reduction assembly 120 is located between the wire pay-off assembly 110 and the wire take-up assembly 130 along the traveling direction, and the initial elongation reduction assembly 120 is used to reduce the length of the initial elongation of the wire 200.

[0063] The initial elongation reduction assembly 120 includes a plurality of electric heating cylinders 121. The plurality of electric heating cylinders 121 are arranged in sequence along the traveling direction X. The initial elongation reduction assembly 120 may further include a housing 122. The plurality of electric heating cylinders 121 are all arranged in the housing 122 and can be fixed on the side wall of the housing 122. The electric heating cylinder 121 has a through hole extending along the traveling direction X, and the through holes in each electric heating cylinder 121 are substantially aligned along the traveling direction X. The electric heating cylinder 121 can convert electrical energy into heat. In Figure 1 and Figure 2 In the illustrated embodiment, three electric heating cylinders 121 are schematically shown, namely a first electric heating cylinder 121a, a second electric heating cylinder 121b, and a third electric heating cylinder 121c.

[0064] The preset temperatures of each heating cylinder 121 can be different, and the preset temperatures of multiple heating cylinders 121 gradually increase first and then gradually decrease along the traveling direction X. In the embodiment of the present application, the temperature of the first heating cylinder 121a is set relatively low. For example, the preset temperature of the first heating cylinder 121a can be set to 70°C - 100°C, the preset temperature of the second heating cylinder 121b can be greater than that of the first heating cylinder 121a, and the preset temperature of the second heating cylinder 121b can be set to 150°C - 200°C. The preset temperature of the third heating cylinder 121c can be less than that of the second heating cylinder 121b, and the preset temperature of the third heating cylinder 121c can also be 70°C - 100°C.

[0065] The wire 200 unwinds from the wire pay-off reel 112 and enters the through-hole of the first heating cylinder 121a at room temperature. Since the preset temperature of the first heating cylinder 121a is relatively low, after the wire 200 enters the first heating cylinder 121a and is preheated, it enters the through-hole of the second heating cylinder 121b.

[0066] The second heating cylinder 121b heats the wire 200. The temperature of the second heating cylinder 121b is relatively high. After the wire 200 is heated, the wire 200 elongates, and the elongation length can compensate for the initial elongation of the wire 200 after erection. Thus, the sag of the wire 200 can be reduced.

[0067] Then, the wire 200 enters the third heating cylinder 121c. Since the preset temperature of the third heating cylinder 121c is less than that of the second heating cylinder 121b, the wire 200 can be preliminarily cooled in the third heating cylinder 121c and then enter the environment.

[0068] After the wire 200 is heated by the first heating cylinder 121a, the second heating cylinder 121b, and the third heating cylinder 121c, the wire 200 is wound on the wire take-up reel 132. The wire 200 has been pretreated before erection, thereby reducing the initial elongation of the wire 200. The wire 200 on the wire take-up reel 132 can be directly erected. Compared with the related art where the initial elongation needs to be reduced during the erection process, it is convenient for the erection construction of the wire 200. In addition, the preset temperatures of the first heating cylinder 121a, the second heating cylinder 121b, and the third heating cylinder 121c increase first and then decrease, which can avoid the wire 200 generating stress again due to a large temperature gradient during heating, affecting the pretreatment effect, and further requiring the treatment of the initial elongation of the wire 200 during the construction process.

[0069] It should be noted that the wire 200 can also be pretreated multiple times through the wire pretreatment device 100.

[0070] The wire pretreatment device 100 provided by the embodiment of the present application is provided with a wire pay-off assembly 110, an initial elongation reduction assembly 120 and a wire take-up assembly 130. The wire pay-off assembly 110, the initial elongation reduction assembly 120 and the wire take-up assembly 130 are arranged in sequence along the advancing direction X of the wire 200. The wire pay-off assembly 110 is used for unwinding the wire 200. The initial elongation reduction assembly 120 includes a plurality of electric heating cylinders 121 arranged in sequence along the advancing direction X. The preset temperatures of the plurality of electric heating cylinders 121 gradually increase first and then gradually decrease along the advancing direction X. After the wire 200 is heated by the plurality of electric heating cylinders 121, it is coiled on the wire take-up assembly 130. Since the temperatures of the plurality of electric heating cylinders 121 gradually increase and then decrease, such a setting can not only reduce the initial elongation of the wire 200, but also prevent the wire 200 from generating stress again due to being subjected to a large temperature gradient during heating. The initial elongation of the wire 200 has been reduced through pretreatment before erection, and the wire 200 on the wire take-up assembly 130 can be directly erected, which is convenient for the erection construction of the wire 200.

[0071] Figure 3 Schematic diagram of the use state of the wire pretreatment device provided by the embodiment of the present application Figure 2 。

[0072] See Figure 3 As shown, the wire pretreatment device 100 further includes a controller 140. Each electric heating cylinder 121 is electrically connected to the controller 140, and a plurality of preset temperatures are set in the controller 140.

[0073] Specifically, the first electric heating cylinder 121a, the second electric heating cylinder 121b and the third electric heating cylinder 121c are all electrically connected to the controller 140. The first preset temperature of the first electric heating cylinder 121a, the second preset temperature of the second electric heating cylinder 121b and the third preset temperature of the third electric heating cylinder 121c can be set in the controller 140.

[0074] Thus, when processing wires 200 with different wire diameters or materials, the first preset temperature, the second preset temperature and the third preset temperature can be conveniently changed through the controller 140 to be applicable to different wires 200.

[0075] Please continue to see Figure 3 As shown, the initial elongation reduction assembly 120 further includes a plurality of temperature sensors 123. The temperature sensors 123 are arranged in one-to-one correspondence with the electric heating cylinders 121, and each temperature sensor 123 is electrically connected to the controller 140.

[0076] The temperature sensor 123 provided on the first electric heating cylinder 121a is the first temperature sensor 123a, the temperature sensor 123 provided on the second electric heating cylinder 121b is the second temperature sensor 123b, and the temperature sensor 123 provided on the third electric heating cylinder 121c is the third temperature sensor 123c. The first temperature sensor 123a, the second temperature sensor 123b, and the third temperature sensor 123c are all electrically connected to the controller 140.

[0077] The first temperature sensor 123a is used to monitor the first temperature on the first electric heating cylinder 121a and transmit the first temperature to the controller 140. The controller 140 is used to compare the first temperature with the first preset temperature. When the first temperature is greater than the first preset temperature, the controller 140 can control the heat generation amount of the first electric heating cylinder 121a to decrease. When the first temperature is less than the first preset temperature, the controller 140 can control the heat generation amount of the first electric heating cylinder 121a to increase. Thus, the temperature of the first electric heating cylinder 121a can be monitored in real time through the first temperature sensor 123.

[0078] The working processes of the second temperature sensor 123b and the third temperature sensor 123c are similar to that of the first temperature sensor 123a, and will not be elaborated here one by one.

[0079] Figure 4 Schematic diagram of the usage state of the wire pretreatment device provided by the embodiment of the present application Figure 3 。

[0080] See Figure 4 As shown, the initial elongation reduction component 120 further includes a camera 124, and the wire pretreatment device 100 further includes a display 150. The display 150 and the camera 124 are both electrically connected to the controller 140.

[0081] The camera 124 is located inside the housing 122 and can be installed on the side wall of the housing 122. The camera 124 can be one or multiple, and is specifically set according to the size of the housing 122 along the traveling direction X.

[0082] The camera 124 can monitor whether there are problems such as wire breakage or knotting of the wire 200 in the initial elongation reduction component 120. The information monitored by the camera 124 can be transmitted to the display 150 through the controller 140, and the operator can conveniently monitor the state inside the initial elongation reduction component 120 through the display 150.

[0083] Figure 5 Schematic diagram of the usage state of the wire pretreatment device provided by the embodiment of the present application Figure 4 。

[0084] See Figure 5As shown, the initial elongation reduction component 120 further includes a cooling component 125, which is disposed between the wire winding component 130 and the electrothermal cylinder 121 at the most distal end along the traveling direction X.

[0085] Specifically, in Figure 5 the illustrated embodiment, the cooling component 125 is disposed between the third electrothermal cylinder 121c and the wire winding component 130, and the cooling component 125 can be fixed on the side wall of the housing 122. After the wire 200 comes out of the third electrothermal cylinder 121c and is cooled by the cooling component 125, it is wound around the wire winding component 130. Thus, the efficiency of the preprocessing process of the wire 200 can be improved.

[0086] In a possible implementation manner, the cooling component 125 is a fan, and the fan is electrically connected to the controller 140.

[0087] The cost of the fan is relatively low, and the temperature of the air blown by the fan is the temperature of the ambient air. Thus, overcooling of the wire 200 and generation of stress can be avoided. The fan is electrically connected to the controller 140, and the controller 140 can set different rotation speeds of the fan according to the wire diameter and material of the wire 200.

[0088] Please continue to refer to Figures 1 to 5 As shown, the wire preprocessing device 100 further includes a wire pay-off driving component 160 and a wire winding driving component 170. The wire pay-off driving component 160 is located between the wire pay-off component 110 and the initial elongation reduction component 120, and the wire winding driving component 170 is located between the wire winding component 130 and the initial elongation reduction component 120.

[0089] The wire pay-off driving component 160 is used to provide a driving force for the wire 200 to unwind from the wire pay-off reel 112, so that the wire 200 enters the initial elongation reduction component 120. After the wire 200 comes out of the initial elongation reduction component 120, the wire winding driving component 170 provides a driving force for the wire 200 to travel, so that the wire 200 is wound around the wire winding reel 132.

[0090] Please continue to refer to Figures 1 to 5 As shown, the wire pay-off driving component 160 includes a first motor 161 and a first tension pulley 162. The first motor 161 is used to drive the first tension pulley 162 to rotate; the wire winding driving component 170 includes a second motor 171 and a second tension pulley 172. The second motor 171 is used to drive the second tension pulley 172 to rotate.

[0091] The first tension pulley 162 has a through hole, and the rotating shaft of the first motor 161 passes through the through hole. The wire 200 is located on the first tension pulley 162. When the first motor 161 rotates, it can drive the first tension pulley 162 to rotate. Thus, the wire 200 can be unwound from the wire pay-off reel 112 and travel along the traveling direction X.

[0092] The second tension wheel 172 has a through hole, the rotating shaft of the second motor 171 is passed through the through hole, the wire 200 is located on the second tension wheel 172. When the second motor 171 rotates, it can drive the second tension wheel 172 to rotate. Thus, the wire 200 can travel along the traveling direction X and be wound around the take-up reel 132.

[0093] In a possible implementation manner, both the first motor 161 and the second motor 171 are electrically connected to the controller 140. The controller 140 pre-sets a first rotation speed and a second rotation speed, and the second rotation speed is greater than the first rotation speed; the controller 140 is used to control the first motor 161 to drive the first tension wheel 162 to rotate at the first rotation speed; the controller 140 is used to control the second motor 171 to drive the second tension wheel 172 to rotate at the second rotation speed.

[0094] After the wire 200 passes through the initial elongation reduction component 120, the length of the wire 200 will increase. Therefore, it is necessary to make the rotation speed of the second motor 171 greater than that of the first motor 161, so that the wire 200 can be wound around the take-up reel 132 in time, and to prevent the wire 200 from accumulating in the initial elongation reduction component 120.

[0095] Specifically, in the embodiment of the present application, both the first motor 161 and the second motor 171 can be electrically connected to the controller 140, set the first rotation speed and the second rotation speed in the controller 140, and make the second rotation speed greater than the first rotation speed. The first motor 161 rotates at the first rotation speed, and the second motor 171 rotates at the second rotation speed. Thus, the rotation speed of the take-up reel 132 is greater than that of the pay-off reel 112.

[0096] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
