[0001] The utility model relates to the technical field of wire clamps, in particular to a heating type crimping device for a T-shaped wire clamp. Background Art
[0002] With the rapid development of social economy, the application of electricity in various fields is constantly expanding, and the requirements for the stability and reliability of power supply are increasing. In overhead power transmission lines, T-type wire clamps are a key connecting component, and their crimping quality directly affects the efficiency and safety of power transmission. If the crimping quality of the wire clamp is poor, it is easy to lead to increased energy loss and contact resistance during power transmission, which in turn causes a series of problems, such as local overheating, line breakage and other faults, which seriously threaten the stable operation of the power system.
[0003] The traditional T-type wire clamp crimping process has many shortcomings in practical applications. During the construction process, due to the influence of factors such as construction technology and material properties, it is often difficult to ensure close contact between the wire clamp and the busbar. For example, during the crimping process, if the pressure applied is uneven or excessive, it may cause deformation of the wire clamp surface, internal stress concentration, or cause a small gap between the wire clamp and the busbar. These situations will affect the conductive performance and cause safety hazards. Utility Model Content
[0004] The purpose of the present utility model is to provide a heating type crimping device for a T-type wire clamp, so as to solve at least any one of the problems raised in the above background technology.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a heating type crimping device for a T-type wire clamp, comprising a carrying mechanism, two clamping mechanisms being provided on the carrying mechanism, and the same electrical mechanism being provided on the carrying mechanism and the two clamping mechanisms;
[0006] The two clamping mechanisms each include a connecting shell, a clamping piece, two threaded handles, four threaded barrels, and a plurality of clamping springs. The four threaded barrels are evenly distributed on one side of the connecting shell and are detachably connected to the connecting shell. The plurality of clamping springs are evenly distributed on the other side of the connecting shell and are fixedly connected to the connecting shell. The clamping piece is fixedly connected to the other end of the plurality of clamping springs.
[0007] The four threaded handles are respectively connected to the four threaded barrels located above and are respectively threadedly connected to the four threaded barrels located below. The four threaded handles are all connected to the two connecting shells.
[0008] The two clips are both made of aluminum.
[0009] Preferably, the electrical mechanism includes a controller, a temperature controller, two thermocouples and a plurality of heating wires, the two thermocouples are electrically connected to the temperature controller, the temperature controller is electrically connected to the controller, and the controller is electrically connected to the plurality of heating wires.
[0010] Preferably, the plurality of heating wires are evenly distributed on the two clips, the plurality of heating wires are detachably connected to the two clips, the two thermocouples are detachably connected to opposite sides of the two connecting shells, and the heat measuring ends of the two thermocouples are in contact with the two clips respectively.
[0011] Preferably, the supporting mechanism includes a base plate, a guide rail, a handle, a slider and a plurality of positioning holes, the guide rail is detachably connected to the top of the base plate, the slider is slidably connected in the guide rail, the plurality of positioning holes are all opened on the base plate, the plurality of positioning holes are evenly distributed on the base plate, and the handle is detachably connected to the right side of the top of the base plate.
[0012] Preferably, the bottom plate is T-shaped.
[0013] Preferably, the bottom of the connecting shell located below is detachably connected to the top of the slider;
[0014] The controller and the temperature controller can be detachably connected to the top of the base plate.
[0015] Preferably, the heating type crimping device for the T-type wire clamp further comprises a wire body and a tube busbar, wherein the wire body is arranged inside the tube busbar, and the tube busbar is arranged between the two clamps and contacts the two clamps.
[0016] The beneficial effects of the utility model are as follows:
[0017] 1. In the present invention, the contact surface is optimized. The clamping mechanism in the present device can adapt to different sizes of busbars through the clamping spring and the adjustable clip structure. After the clip is heated and softened, the force of the clamping spring can increase the contact surface between the clip and the busbar and make them close together. This method effectively solves the problem of loose contact surface that may exist in the traditional crimping process, improves the construction quality of the wire clamp crimping, and reduces the risk of overheating, discharge and other failures caused by poor contact surface.
[0018] Adapting to material characteristics, the clamps are made of aluminum, utilizing its tendency to soften slightly when heated for crimping. Without compromising the clamp's inherent performance and technical specifications, the softening and clamping process improves construction quality and reduces the likelihood of metal textures developing into cracks under prolonged external forces, thereby enhancing the safety of power equipment operation.
[0019] 2. In the present invention, the thermocouple, temperature controller and controller in the temperature monitoring and feedback electrical mechanism constitute a precise temperature control system. The thermocouple can accurately detect the heat of the clip and transmit the temperature information to the temperature controller. The temperature controller makes a judgment based on the preset temperature range and sends a signal to the controller when the temperature exceeds or falls below the set range.
[0020] Stable heating control The controller controls the heating process of the heating wire according to the signal of the temperature controller. When the temperature is lower than the set lower limit, the controller closes the relay to start heating the heating wire; when the temperature reaches or exceeds the set upper limit, the controller disconnects the relay to stop heating the heating wire. This precise temperature control ensures the stability of the clip heating process, avoids the situation where the characteristics of the aluminum material are damaged due to excessively high temperature or the processing effect is poor due to excessively low temperature, thereby ensuring the stability of the wire clamp crimping quality.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] The utility model provides Figure 1-6 The heating type crimping device for a T-type wire clamp shown in the figure includes a carrying mechanism, two clamping mechanisms are provided on the carrying mechanism, and the same electrical mechanism is provided on the carrying mechanism and the two clamping mechanisms;
[0030] Both clamping mechanisms include a connecting shell 7, a clamping piece 14, two threaded handles 10, four threaded barrels 11, and a plurality of clamping springs 12. The four threaded barrels 11 are evenly distributed on one side of the connecting shell 7 and are detachably connected to the connecting shell 7. The plurality of clamping springs 12 are evenly distributed on the other side of the connecting shell 7 and are fixedly connected to the connecting shell 7. The clamping piece 14 is fixedly connected to the other end of the plurality of clamping springs 12.
[0031] The four threaded handles 10 are respectively connected to the four threaded barrels 11 located above and are respectively threadedly connected to the four threaded barrels 11 located below. The four threaded handles 10 are all connected to the two connecting shells 7.
[0032] The two clips 14 are both made of aluminum.
[0033] The user can adjust the distance between the two connecting shells 7 by cooperating with the threaded handle 10 and the threaded cylinder 11. As the connecting shell 7 is adjusted, the clip 14 is displaced and can be tightly attached to the busbars 16 of different sizes. The clip 14 is then heated by an electrical mechanism. As the clip 14 is heated, the aluminum clip 14 softens slightly. At this time, the hardness is low and the ductility is strong. As the clip 14 softens, under the action of the clamping spring 12 on the external force, the contact area with the busbar 16 can be increased and tightly attached to the busbar 16, thereby improving the construction quality of the wire clamp and tightening, which brings convenience to the user.
[0034] The electrical mechanism includes a controller 4 , a temperature controller 6 , two thermocouples 15 and a plurality of heating wires 13 . The two thermocouples 15 are electrically connected to the temperature controller 6 , the temperature controller 6 is electrically connected to the controller 4 , and the controller 4 is electrically connected to the plurality of heating wires 13 .
[0035] The heating wire 13 is the part that heats the clip 14. The heat of the clip 14 can be detected by the thermocouple 15. The thermocouple 15 will transmit the detected heat information to the temperature controller 6. When the temperature controller 6 detects that the temperature of the wire clamp exceeds or is lower than the set range, it will send a signal to the controller 4 through this output end to inform the current temperature status. When the temperature controller 6 detects that the temperature is lower than the set lower limit, the controller 4 will close the corresponding relay to start heating the heating wire. When the temperature reaches or exceeds the set upper limit, the controller 4 will disconnect the relay and stop heating the heating wire 13. In summary, the temperature control of the clip 14 is achieved.
[0036] Multiple heating wires 13 are evenly distributed on the two clips 14 , and the multiple heating wires 13 are detachably connected to the two clips 14 . Two thermocouples 15 are detachably connected to the opposite sides of the two connecting shells 7 , and the heat measuring ends of the two thermocouples 15 are in contact with the two clips 14 .

The guide rail 2 is detachably connected to the top of the base plate 1, and the slider 8 is slidably connected in the guide rail 2. The plurality of positioning holes 9 are all opened on the base plate 1, and the plurality of positioning holes 9 are evenly distributed on the base plate 1. The handle 5 is detachably connected to the right side of the top of the base plate 1.
[0038] The base plate 1 is equipped with multiple positioning holes 9 to facilitate the user to position the base plate 1. The base plate 1 can stably support the components on it. Through the guide rail 2 and the slider 8, the clip 14 can be slidably adjusted in a specific direction to adapt to changes such as thermal expansion and contraction during heating.
[0039] The bottom plate 1 is T-shaped.
[0040] The T-shaped design and the handle 5 make it easy for the user to pick up and move the device, bringing convenience to the user.
[0041] The bottom of the connecting shell 7 located below is detachably connected to the top of the slider 8;
[0042] The controller 4 and the temperature controller 6 can both be detachably connected to the top of the base plate 1 .
[0043] The heating type crimping device for the T-type wire clamp further includes a wire body 3 and a tube busbar 16 . The wire body 3 is arranged in the tube busbar 16 . The tube busbar 16 is arranged between the two clamps 14 and contacts the two clamps 14 .
[0044] The heat treatment is carried out by utilizing the characteristics of the aluminum material itself, and the contact between the clip 14 and the tube busbar 16 is carried out without destroying the performance of the clip 14 itself and various technical indicators. This improves the construction quality and reduces the texture in the metal material from evolving into cracks under the long-term action of external forces, which poses a safety hazard to the operation of power equipment. The research and development and application not only improve safety, but also save operating time and reduce labor intensity, and have great application and promotion value.
