Description

Technical Field

[0001] The invention relates to the technical field of electric power construction equipment, and in particular to a pressure welding wire nose device with a gas monitoring function. Background Art

[0002] The amount of secondary AC wiring at the root of the current transformer, the root of the voltage transformer, the back panel of the protection and measurement and control devices is relatively large, and the amount of crimping wire noses for the corresponding wiring is also relatively large. In new or expanded substations, workshops and other work places, the number of wire noses that need to be crimped for related current transformers, voltage transformers, protection and measurement and control equipment is huge. For example, there are about 10,000-20,000 wire noses that need to be crimped in a newly built 330 kV substation, and it usually takes about 20 days for 5 people to complete the wiring. If the crimping between the wire nose and the exposed copper wire is not firm, with the passage of operating time, thermal expansion and contraction, and the influence of external forces on the secondary wiring, the wiring and the wire nose may fall off, which will cause the secondary circuit of the voltage transformer to lose pressure, the related protection voltage function to fail, the secondary circuit of the current transformer to open, the current transformer to burn, and the protection to refuse to operate or malfunction.

[0003] In order to improve the connection firmness between the wire nose and the copper wire, the common measure currently taken when crimping the wire nose and the copper wire is to tin the connection. However, the existing wire nose crimping tools are suitable for use in a flat environment, and require both hands to perform crimping and tinning operations. The actual crimping work is often carried out in a small, high and complex environment. The existing crimping tools are not only inconvenient to use, but also have the safety risk of tin liquid spilling and injuring people.

DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0025] See also Figure 1-7 The embodiment of the present invention provides a crimping welding wire nose device with a gas monitoring function, comprising: a pressure clamp body 10, a tin feeding mechanism 20, a heating mechanism 30 and a gas monitoring mechanism 40; the pressure clamp body 10 comprises a crimping jaw 50 for crimping the wire nose and the copper wire; the tin feeding mechanism 20 is arranged above one end of the crimping jaw 50, for fixing and installing the solder wire, and feeding the solder wire to the crimping lead mouth, the heating mechanism 30 is arranged on the pressure clamp body 10, for heating and melting the solder wire at the crimping jaw 50, so that the generated tin liquid is released to the connection between the wire nose and the copper wire at the crimping jaw 50; the gas monitoring mechanism 40 is arranged on the pressure clamp body 10, for monitoring toxic gases in the surrounding environment.

[0026] In this embodiment, the solder wire can be automatically delivered to the crimping jaws 50 by the tin delivery mechanism 20 during each operation, and the solder wire at the crimping jaws 50 is melted by the heating mechanism 30, and then the melted tin liquid will fall on the wire nose and copper wire crimped at the crimping jaws 50, thereby improving the crimping firmness of the wire nose and copper wire. Moreover, the device is easy to use, and the tin liquid is not easy to spill, and the risk of tin liquid spilling and injuring people will be greatly reduced. In addition, the present embodiment can monitor the toxic gas in the surrounding environment in real time through the gas monitoring mechanism 40, so as to promptly remind the operator when the concentration of the toxic gas reaches a certain value, thereby reducing the risk of poisoning of the operator when working in a confined space.

[0027] The pressure clamp body 10 may specifically include an upper clamping body 11, an upper handle 12, a connecting piece 13 and a lower clamping body 14; The rear end of the upper clamping body 11 is rotatably connected to the front end of the upper handle 12 via a first pin 15, and the lower end is rotatably connected to the lower clamping body 14 via a second pin 16; the lower end of the upper handle 12 is rotatably connected to one end of the connecting piece 13 via a third pin 17, and the other end of the connecting piece 13 is rotatably connected to the lower clamping body 14 via a fourth pin 18; the crimping jaws 50 are composed of an upper groove opening 51 at the front end of the upper clamping body 11 and a lower groove opening 52 at the front end of the lower clamping body 14.

[0028] In this embodiment, when operating the pressure pliers body 10 to open the crimping jaws 50, the operator holds the pressure pliers body 10 to open the upper handle 12 and the tail of the lower clamping body 14, that is, when the tail of the upper handle 12 moves upward, the upper handle 12 will rotate with the third pin shaft 17 rotatably connected to the connecting member 13 as a support point, and the front end of the upper handle 12 will move downward, thereby driving the tail end of the upper clamping body 11 to move downward; at this time, when the tail end of the upper clamping body 11 rotates downward, it will rotate with the second pin shaft 16 as a support point, so that the front end of the upper clamping body 11 moves upward, that is, the crimping jaws 50 are opened. The crimping jaws 50 can be closed by the reverse operation.

[0029] It is easy to understand that the tail ends of the upper handle 12 and the lower clamping body 14 should be covered with insulating rubber sleeves to facilitate the operation of the operator and protect the operator's hands.

[0030] In one embodiment, the front end of the upper clamping body 11 may be provided with N upper groove openings 51 of different specifications, and the front end of the lower clamping body 14 may be correspondingly provided with lower groove openings 52 matching each upper groove opening 51 , so that each upper groove opening 51 and lower groove opening 52 constitutes N crimping jaws 50 of different specifications.

[0031] In this embodiment, N grooves of different specifications can be set at the front end of the upper clamping body 11 and the front end of the lower clamping body 14, where N is greater than or equal to 2, so that a plurality of crimping jaws 50 of different specifications can be formed, thereby realizing the crimping operation of wire noses and copper wires of different specifications. For example, in a batch of crimping operations with multiple specifications at the same time, the operator does not need to carry multiple wire nose crimping tools, but only needs to carry the device provided by this embodiment to meet the crimping operation of wire noses of multiple specifications, and there is no need to frequently change the wire nose crimping tools, which is more convenient to use.

[0032] The tin feeding mechanism 20 may mainly include: a tin wire guide tube 21, a tin wire conveying assembly 22 and a tin wire winding assembly 23; The tin wire winding assembly 23 is fixedly mounted on one end of the upper clamping body 11 close to the upper handle 12, and is used for winding the solder wire; one end of the tin wire guide tube 21 is connected to the upper groove opening 51 of the upper clamping body 11, and the other end faces the tin wire conveying assembly 22; the tin wire conveying assembly 22 is fixedly mounted on the upper clamping body 11, and is located between the tin wire winding assembly 23 and the tin wire guide tube 21, so that the solder wire extending from the tin wire winding assembly 23 passes through the tin wire conveying assembly 22 and then enters the tin wire guide tube 21; the tin wire conveying assembly 22 is transmission-connected to the upper handle 12, and is used to drive the tin wire conveying assembly 22 to convey the tin wire forward when the upper handle 12 is pressed downward.

[0033] In this embodiment, the tin wire conduit 21 should be connected to the upper groove opening 51 of the upper clamping body 11. That is, a through hole 111 is opened at the upper groove opening 51 of the upper clamping body 11, which is connected to the upper part of the upper clamping body 11, and the tin wire conduit 21 extends from the upper part of the upper clamping body 11 to guide the tin wire to the upper groove opening 51.

[0034] The tin wire conveying assembly 22 may specifically include: a door frame 221, an upper pressing wheel 222, a lower pressing wheel 223, a push rod 224, a spring 225, a first gear 226, a second gear 227, a first connecting rod 228 and a second connecting rod 229; The door frame 221 is fixedly mounted on the upper clamping body 11, and the lower pressing wheel 223 is fixedly mounted in the door frame 221. The door frame 221 is provided with sliding grooves on the two side plates above the lower pressing wheel 223. The upper pressing wheel 222 is slidably arranged on the sliding grooves on both sides, and the shaft of the upper pressing wheel 222 extends out of the two side plates of the door frame 221; the shafts of the upper pressing wheel 222 extending out of the two side plates of the door frame 221 are fixedly connected with a push rod 224, and the other end of the push rod 224 extends upward from the top plate of the door frame 221; each A spring 225 is sleeved on the push rod 224, and the spring 225 is located between the lower side of the top plate of the door frame 221 and the axis of the upper pressure wheel 222; the first gear 226 is coaxially fixedly connected to the lower pressure wheel 223, the second gear 227 is fixedly installed on the upper clamping body 11, and is meshed with the first gear 226, one end of the first connecting rod 228 is rotatably connected to the second gear 227, and the other end is rotatably connected to one end of the second connecting rod 229, and the other end of the second connecting rod 229 is rotatably connected to the upper handle 12.

[0035] In this embodiment, the solder wire is wound on the tin wire winding assembly 23, and the extended solder wire passes between the upper pressing wheel 222 and the lower pressing wheel 223, and then is introduced into the crimping jaw 50 from the tin wire conduit 21. In this way, when the operator presses down the upper handle 12 of the pressure clamp body 10, the upper handle 12 will drive the first connecting rod 228 and the second connecting rod 229 to move forward, and then the first connecting rod 228 will drive the second gear 227 to rotate clockwise, and the first gear 226 meshing with the second gear 227 will move counterclockwise, and then the lower pressing wheel 223 will also move counterclockwise, so that the solder wire held above the lower pressing wheel 223 can be conveyed forward. The upper pressing wheel 222 can generate a downward force through the pressure of the spring 225, and then cooperate with the lower pressing wheel 223 to clamp the solder wire between the upper pressing wheel 222 and the lower pressing wheel 223, and complete the purpose of conveying forward.

[0036] In one embodiment, since the crimping jaws 50 are provided with different specifications at the same time. Therefore, in one embodiment, it is considered that N specifications of crimping grooves 2210 are provided on the upper crimping wheel 222 and the lower crimping wheel 223, which are used for solder wires of different specifications to pass through and press the solder wires; the tin wire conduit 21 includes N pieces, one end of each tin wire conduit 21 is connected to an upper groove opening 51 of a specification on the upper clamping body 11, and the other end faces the direction of the crimping groove 2210 of the tin wire conveying assembly 22. In this way, in practice, according to the specifications of the specific solder wire to be clamped, crimping grooves 2210 of different specifications can be selected, and the solder wire can be pressed into the corresponding crimping groove 2210, so as to avoid the solder wire changing direction as the direction of the solder wire on the tin wire winding assembly 23 changes continuously when the solder wire is released, which affects the conveying of the solder wire.

[0037] Of course, it should be pointed out that the wire pressing grooves 2210 of various specifications can satisfy: when the solder wire of the corresponding specifications is pressed into the wire pressing grooves 2210 on the lower pressing wheel 223, the two sides of the wire pressing grooves 2210 of the lower pressing wheel 223 can just tightly clamp the solder wire. At the same time, after the corresponding wire pressing grooves 2210 of the upper pressing wheel 222 are lowered, pressure can be generated on the upper surface of the solder wire, so that the solder wire can be conveyed forward.

[0038] The tin wire winding assembly 23 may specifically include: a tin wire winding shaft 231, a fixing frame 232, a third gear 233 and a reverse locking member 234; The fixing frame 232 is fixedly mounted on the upper clamping body 11, the tin wire winding shaft 231 is rotatably sleeved on the fixing frame 232, the third gear 233 is sleeved on the fixing frame 232 and fixedly connected to the side of the tin wire winding shaft 231; a reverse locking member 234 is installed on the upper end of the fixing frame 232, and the reverse locking member 234 is meshedly connected with the third gear 233 in a manner to prevent the third gear 233 from rotating in the reverse direction.

[0039] In this embodiment, the tin wire winding shaft 231 is used to wind the solder wire. As the tin wire conveying assembly 22 conveys the solder wire forward, the tin wire winding shaft 231 is driven to rotate, thereby continuously releasing the solder wire. In addition, in order to prevent the tin wire winding shaft 231 from rotating in the reverse direction, which causes the solder wire to be wound in disorder, it is considered to set a third gear 233 and a reverse locking member 234. The third gear 233 is composed of teeth with a certain tilt angle, and the reverse locking member 234 is a hook-shaped mechanism with one tooth, which can mesh with the third gear 233 and can make the third gear 233 rotate forward to release the solder wire, and is stuck when the third gear 233 rotates backward to prevent the reverse rotation of the tin wire reel.

[0040] The heating mechanism 30 may mainly include a heating component 31 and a heating start-stop component 32, and the heating component 31 is electrically connected to the heating start-stop component 32; The heating components 31 are respectively arranged on the upper clamping body 11 near each upper groove opening 51 for heating and melting the solder wire at the corresponding position; the heating start-stop component 32 is arranged on the upper handle 12 for controlling the start and stop of the heating component 31 .

[0041] In this embodiment, the heating component 31 can be a heating device such as a heating wire, which can be arranged in a through hole 111 of the upper clamping body 11 near the upper groove position, that is, the front end of the solder wire near the upper groove is heated to produce tin liquid dripping onto the wire nose and the copper wire. Of course, the specific heating length of the solder wire can be set according to the required amount of tin liquid to avoid insufficient or excessive tin plating. The heating start-stop component 32 can be a heating control button, which can be set on the upper handle 12, so that the operator can operate it with one hand. That is, while holding the pressure clamp body 10, the control button can be pressed by the finger to make the heating component 31 work and heat the solder wire. Then the other hand of the operator can be released to hold the wire nose and the copper wire to better complete the crimping operation.

[0042] In addition, the heating mechanism 30 may further include a power adjustment component 33 disposed on the upper clamping body 11, and the power adjustment component 33 is electrically connected to the heating component 31, and is used to adjust the heating power of the heating component 31. In this way, the operator can adjust the heating power of the heating component 31 according to factors such as the required heating temperature of the solder wire and the required melting time of the solder wire to adapt to more scenarios.

[0043] In one embodiment, the gas monitoring mechanism 40 may include a toxic gas concentration detection component and an alarm component electrically connected thereto; The toxic gas concentration detection component is used to detect the toxic gas concentration in the surrounding environment, and to issue an alarm through the alarm component when the toxic gas concentration exceeds a preset threshold.

[0044] In this embodiment, the concentration of toxic gases in the working environment can be monitored in real time through the toxic gas concentration monitoring component, so that when the toxic gas concentration reaches a preset threshold, an alarm can be issued through the alarm component. In this way, when working in a confined space, the operator can know in time whether there is a risk of poisoning in the working environment, so that when there is a risk of poisoning, the operator can stop working in time, avoid the current environment, or deal with the toxic gases in the current environment.

[0045] In order to prevent the operator from continuing to work when the concentration of toxic gas reaches the alarm concentration, it is considered to electrically connect the alarm component and the heating component 31 so that when the alarm component generates an alarm, the heating component 31 automatically stops working.

[0046] In this solution, the power supply can be battery powered, or a power port can be set to connect to the mains.

[0047] The crimping welding wire nose device with gas monitoring function provided by this solution mainly includes the following processes when performing wire nose crimping operations: 1. Install solder wire The solder wire needs to be installed during the first crimping. First, determine the specifications of the wire nose and copper wire to be crimped, taking specification A as an example; determine the specifications of the selected solder wire, taking specification a as an example; then install the solder wire coil in the tin wire winding assembly 23, and pass one end of the solder wire through the specification a crimping groove 2210 on the tin wire conveying assembly 22, and then introduce it into the tin wire guide tube 21 corresponding to the specification A crimping jaw 50, until the front end of the solder wire is close to the crimping jaw 50.

[0048] 2. Crimping operation (1) After adjusting the configuration of the wire nose and copper wire to be crimped, place them in the A-specification crimping jaws 50, and operate the pressure clamp body 10 to press down to clamp the wire nose and copper wire in the crimping jaws 50; (2) Press and hold the heating start / stop button to heat the solder wire at the crimping jaw 50.
