Description

Technical Field

[0001] This application relates to the field of wire testing technology, and in particular to a wire combustion testing machine. Background Technology

[0002] A combustion tester is a testing device used to evaluate the combustion behavior of materials or products under specific conditions. It can detect whether a sample is flammable, the speed of combustion, whether molten droplets are produced during combustion, and whether the flame will automatically extinguish after combustion by simulating flames or other fire sources. Thus, it plays an important role in scientifically evaluating the self-extinguishing ability, propagation ability, secondary disasters, and survivability of wires.

[0003] Regarding the aforementioned technologies, existing wire burning test machines can generally only clamp wires vertically or horizontally, and the angle of the combustion torch is usually fixed. This means that when testing standards such as GB / T12666.3 require the wire to be clamped and tested at a certain angle relative to the vertical direction, other specialized wire burning test machines for tilt testing are needed, thus reducing the scope of application of wire burning test machines. Therefore, improvements are needed. Summary of the Invention

[0004] To facilitate testing of tilted wires, this application provides a wire burning test machine.

[0005] This application provides a wire burning test machine, which adopts the following technical solution: A wire burning test machine includes a body, within which a test platform, a test mechanism, and a clamping mechanism are disposed. The clamping mechanism includes an upper adjusting frame, an upper clamping frame, a lower clamping frame, and a transmission frame. The upper adjusting frame is slidably connected to the test platform, and the sliding direction is the height direction of the test platform. The upper clamping frame is used to slide relative to the upper adjusting frame, and the sliding direction is different from the sliding direction of the upper adjusting frame. The two ends of the transmission frame are respectively used to rotate relative to the upper clamping frame and the test platform. The lower clamping frame is disposed at the bottom of the transmission frame. The upper and lower clamping frames are respectively used to clamp the two ends of the wire. The test mechanism is used to burn the ends of the clamped wire.

[0006] By adopting the above technical solution, compared with the existing wire burning test machines, which can generally only clamp wires in the vertical or horizontal direction, and thus require specialized wire burning test machines for tilting tests when testing according to standards such as GB / T12666.3, the present application, through the setting of the clamping mechanism, allows the tester to simply rotate the transmission frame relative to the test table when the wire needs to be tilted. This causes the transmission frame to slide relative to the upper adjusting frame, which in turn causes the upper adjusting frame to slide, thereby tilting the transmission frame and maintaining its current state at both ends. This allows the wire to be tilted and maintained in this tilted state, enabling the present application to test the wire according to standards such as GB / T12666.3. This effectively improves the scope of application and practicality of the present application, and also ensures that the wire is maintained in a nearly taut state when vertical, effectively guaranteeing the test results.

[0007] Preferably, the upper adjusting frame is further provided with an adjusting mechanism, the adjusting mechanism including an adjusting frame and a sleeve frame, the adjusting frame being slidably connected to the upper adjusting frame and having a different sliding direction than the upper adjusting frame, the sleeve frame being rotatably connected to the adjusting frame and sleeved on the top of the transmission frame and slidably connected to the transmission frame, and the upper clamping frame being provided on the top of the transmission frame.

[0008] By adopting the above technical solution and setting the adjustment mechanism, the tester can adjust the distance between the upper clamping frame and the lower clamping frame by driving the sleeve frame to slide relative to the transmission frame according to the length of the wire to be tested. This allows the system to adapt to wires of different lengths, effectively increasing the applicability and practicality of this application, and facilitating the tester's testing of wires of different lengths.

[0009] Preferably, the sleeve frame is further provided with a locking mechanism, which includes a locking frame, an abutment frame, and an elastic element. The abutment frame is disposed on the adjusting frame, and a guide surface is provided at one end away from the adjusting frame. The guide surface extends along the rotation axis of the sleeve frame. The locking frame is slidably connected to the sleeve frame, with one end abutting against the abutment frame and the other end passing through the sleeve frame and inserted into the transmission frame. The elastic element is used to allow the locking frame to continuously abut against the abutment frame through its own elastic force.

[0010] By adopting the above technical solution and setting the locking mechanism, when the transmission frame shifts from a vertical position, the adjusting frame 61 and the sleeve frame rotate relative to each other, thereby changing the contact point between the locking frame and the adjusting frame, and causing the locking frame to slide and gradually insert itself onto the transmission frame, automatically locking the transmission frame and the sleeve frame. This ensures that the clamped wire is in a nearly taut state, guaranteeing the test results. Furthermore, it eliminates the need for manual locking between the sleeve frame and the transmission frame by the test personnel, effectively facilitating the operation of the test personnel and realizing the linkage between the sleeve frame and the locking frame.

[0011] Preferably, the bottom of the transmission frame is also provided with a lower adjustment frame, which is slidably connected to the test bench and the sliding direction is the height direction of the test bench. The test bench is also provided with a locking member, which is used to lock the lower adjustment frame on the test bench.

[0012] By adopting the above technical solution and setting the lower adjustment frame, the test personnel can finely adjust the distance between the lower adjustment frame and the test mechanism according to the specific test requirements, thereby adapting to different test needs and effectively ensuring the applicability and practicality of this application, so as to meet the needs of various test standards.

[0013] Preferably, the test mechanism includes a mounting frame and a combustion torch. The mounting frame is slidably connected to the test bench and slides in a horizontal direction. The combustion torch is mounted on the mounting frame and located below the lower clamping frame. The mounting frame is also provided with an extension rod, one end of which extends toward the inner wall of the machine body.

[0014] By adopting the above technical solution, the setup of the mounting frame and the burner allows the test personnel to push or pull the mounting frame to slide by holding the extension rod, thereby causing the burner on the mounting frame to move along with the mounting frame, thus achieving adjustment of the burner's position so that the burner can adapt to different tilt angles of the wire.

[0015] Preferably, the mounting frame is also provided with a rotating mechanism, which includes a rotating frame and a rotating assembly. The rotating frame is rotatably connected to the mounting frame, the combustion torch is mounted on the rotating frame, and the rotating assembly is used to drive the rotating frame to rotate.

[0016] By adopting the above technical solution and setting the rotating mechanism, the test personnel can drive the rotating frame to rotate through the rotating component, thereby enabling the rotating frame to drive the combustion torch to rotate as well, and thus adjust the tilt angle of the combustion torch to meet the needs of different test requirements, effectively increasing the applicability and practicality of this application.

[0017] Preferably, the rotating assembly includes a sliding frame, a driving frame, and a driving component. The sliding frame is slidably connected to the mounting frame. One end of the driving frame is rotatably connected to the sliding frame, and the other end is rotatably connected to the rotating frame. The rotatable connection point is different from the rotatable connection point of the sliding frame itself. The driving component drives the sliding frame to slide.

[0018] By adopting the above technical solution and setting the rotating component, the test personnel can drive the sliding frame to slide through the driving component, thereby driving the rotating frame to rotate through the driving frame, thus realizing the driving of the rotating frame and converting the rotation of the rotating frame into the sliding of the sliding frame. This facilitates the setting of the driving component, allowing it to be close to the end of the extension rod for easy driving by the test personnel.

[0019] Preferably, the driving component includes an intermediate frame and a driving frame. One end of the driving frame is rotatably connected to the sliding frame, and the other end passes through the intermediate frame and is slidably connected to the intermediate frame. The intermediate frame is rotatably connected to the setting frame.

[0020] By adopting the above technical solution and setting the driving component, the test personnel can rotate the driving frame, thereby causing the driving frame to slide relative to the intermediate frame, which in turn drives the sliding frame to slide, thus achieving the driving of the sliding frame. This allows the test personnel to drive the sliding frame to slide at the end of the extension rod, thereby facilitating the driving of the sliding frame.

[0021] Preferably, the test bench is also provided with a fixing mechanism, which includes a fixing frame and an unlocking component. The fixing frame is slidably connected to the setting frame, and one end passes through the sliding frame and is inserted into the test bench. The unlocking component is used to drive the fixing frame to slide.

[0022] By adopting the above technical solution and setting the fixing mechanism, after adjusting the tilt angle of the rotating frame and the position of the setting frame, the test personnel can drive the fixing frame to slide by unlocking the component, so that one end of the fixing frame passes through the sliding frame and is inserted into the test platform, thereby realizing the synchronous locking of the setting frame and the rotating frame, and thus ensuring the stability of the setting frame and the rotating frame.

[0023] Preferably, the unlocking assembly includes a rotating rod and a transmission rod, the rotating rod being rotatably connected to the intermediate frame, one end of the transmission rod being rotatably connected to the rotating rod, and the other end being rotatably connected to the retaining frame.

[0024] By adopting the above technical solution and setting the unlocking component, the test personnel can rotate the rotating rod, which in turn drives the retaining frame to slide through the transmission rod, thereby driving the retaining frame. This also allows the test personnel to drive the rotating rod to rotate while holding the drive frame, thus facilitating the driving of the retaining frame.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The clamping mechanism is designed so that when the wire needs to be tilted, the tester only needs to rotate the transmission frame relative to the test table. This causes the transmission frame to slide relative to the upper adjustment frame, which in turn causes the upper adjustment frame to slide, thus tilting the transmission frame. The two ends of the transmission frame can maintain their current state, allowing the wire to tilt and maintain the tilted state. This enables the application to test the wire according to test standards such as GB / T12666.3, effectively improving the scope of application and practicality of the application. Furthermore, it allows the wire to maintain an approximately taut state when it is vertical, effectively ensuring the test results. The arrangement of the adjustment mechanism and the locking mechanism allows the tester to adjust the distance between the upper and lower clamping frames by sliding the drive sleeve frame relative to the transmission frame according to the length of the wire to be tested. This adapts to wires of different lengths, effectively increasing the applicability and practicality of this application. It also facilitates the tester's testing of wires of different lengths and enables automatic locking between the transmission frame and the sleeve frame, eliminating the need for manual locking by the tester. This effectively simplifies the tester's operation and achieves linkage between the sleeve frame and the locking frame. The rotating mechanism allows the test personnel to drive the rotating frame to rotate via the rotating components, which in turn causes the combustion torch to rotate as well. This allows for adjustment of the combustion torch's tilt angle to meet different test requirements, effectively increasing the applicability and practicality of this application.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a wire burning test machine. (Refer to...) Figure 1 and Figure 2 The wire burning test machine includes a body 1, within which are a test platform 2, a test mechanism 3, and a clamping mechanism 4. The clamping mechanism 4 includes an upper adjusting frame 41, an upper clamping frame 42, a lower clamping frame 43, and a transmission frame 44. The upper adjusting frame 41 is slidably connected to the test platform 2, and its sliding direction is the height direction of the test platform 2. The upper clamping frame 42 is used to slide relative to the upper adjusting frame 41, and its sliding direction is different from that of the upper adjusting frame 41. The two ends of the transmission frame 44 are respectively used to rotate relative to the upper clamping frame 42 and the test platform 2. The lower clamping frame 43 is located at the bottom of the transmission frame 44, and the upper clamping frame 42 and the lower clamping frame 43 are respectively used to clamp the two ends of the wire. The test mechanism 3 is used to burn the ends of the clamped wire.

[0034] Reference Figure 1 An opening is provided on one side wall of the machine body 1 to allow the test bench 2 to be installed inside the machine body 1, and to facilitate the adjustment of the clamping mechanism 4 and the test mechanism 3 within the opening by the test personnel. A door is also provided on the opening, and the door is rotatably connected to the machine body 1. The test bench 2 is fixedly installed on the bottom wall inside the opening of the machine body 1 by bolts.

[0035] Reference Figure 2The bottom of the transmission frame 44 is also provided with a lower adjustment frame 45. In this embodiment, the number of lower adjustment frames 45 is set to two, and they are located on opposite sides of the test bench 2 respectively. Each lower adjustment frame 45 is sleeved on the top rod of the test bench 2 and is slidably connected to the test bench 2, and the sliding direction is set to the vertical direction (i.e., the height direction of the test bench 2).

[0036] Reference Figure 2 The bottom of the transmission frame 44 and each lower adjustment frame 45 are rotatably connected by a pin. In this embodiment, the lower clamping frame 43 is installed at the bottom of the transmission frame 44 and is configured as a frame body and two clamping blocks. The frame body is fixedly connected to the transmission frame 44, and the two clamping blocks are slidably connected to the frame body, with the sliding direction being the length direction of the frame body. Each clamping block is provided with a fixing screw for fixing the clamping block and the frame body. The screw is tightened on the clamping block and abuts against the frame body, thereby fixing the clamping block and the frame body by friction. The clamping method and structure of the frame body and the two clamping blocks are existing technologies, so they will not be described in detail here.

[0037] Reference Figure 2 In this embodiment, two upper adjustment frames 41 are provided, corresponding to the lower adjustment frames 45, and both are located directly above the corresponding lower adjustment frames 45. Each upper adjustment frame 41 is sleeved on the frame at the top of the test bench 2 and is slidably connected to the test bench 2, with the sliding direction being vertical. The test bench 2 is also provided with a locking member 5. In this embodiment, the locking member 5 is provided with several fixing screws. These screws are tightened onto the corresponding upper adjustment frame 41 or lower adjustment frame 45 and abut against the test bench 2, thereby fixing the upper adjustment frame 41 or lower adjustment frame 45 to the test bench 2 through friction.

[0038] Reference Figure 2 Each upper adjusting frame 41 is also equipped with an adjusting mechanism 6. Each adjusting mechanism 6 includes an adjusting frame 61 and a mounting frame 62. Each adjusting frame 61 is mounted on the corresponding upper adjusting frame 41 and is slidably connected to the corresponding upper adjusting frame 41. The sliding directions are all parallel and horizontal. The mounting frame 62 is located between two adjusting frames 61 and is rotatably connected to the corresponding adjusting frame 61 via a pin.

[0039] Reference Figure 2 , Figure 3 and Figure 4Each sleeve 62 is fitted onto the top of the transmission frame 44 and is slidably connected to the transmission frame 44, with the sliding direction being the length direction of the transmission frame 44. Each sleeve 62 is also provided with a locking mechanism 7, which includes a pre-locking component 71, a locking frame 72, an abutment frame 73, and an elastic element 74. Each pre-locking component 71 includes a pre-locking block 711 and a pre-locking element 712. Each pre-locking block 711 is disposed in the corresponding sleeve 62 and is slidably connected to the corresponding sleeve 62, with the sliding direction being the sliding direction between the transmission frame 44 and the sleeve 62.

[0040] Reference Figure 2 and Figure 3 Each pre-locking block 711 has one end extending into the cavity of the corresponding sleeve 62, and is hemispherical in shape. Each block is inserted into the side wall of the transmission frame 44. The side wall of the transmission frame 44 also has several hemispherical grooves for the ends of the pre-locking blocks 711 to be inserted, thus performing initial locking. In this embodiment, the pre-locking elements 712 are all configured as pressure springs. Each pressure spring is sleeved on the corresponding pre-locking block 711, with one end abutting against the pre-locking block 711 and the other end abutting against the inner wall of the corresponding sleeve 62.

[0041] Reference Figure 2 and Figure 4 Each abutment frame 73 is set on the corresponding mixing frame 61 and extends circumferentially along the rotation axis between the corresponding mixing frame 61 and the locking frame 72. Each abutment frame 73 has a guide surface on the side away from the corresponding mixing frame 61, and the thickness of each abutment frame 73 decreases from the side closest to the frame on the test bench 2 to the other side.

[0042] Reference Figure 2 and Figure 4 Each locking frame 72 is slidably connected to the corresponding sleeve frame 62 via a sliding groove, with one end abutting against the guide surface of the corresponding abutment frame 73, and the other end passing through the corresponding sleeve frame 62 and inserted into the side wall of the transmission frame 44 to lock the sleeve frame 62 and the transmission frame 44. The transmission frame 44 also has several slots for inserting locking grooves, and these slots extend along the length of the transmission frame 44. In this embodiment, the elastic element 74 is a pressure spring, which is sleeved on the corresponding locking frame 72, with one end abutting against the locking frame 72 and the other end abutting against the corresponding sleeve frame 62.

[0043] Reference Figure 2In this embodiment, the upper clamping frame 42 is installed on the top of the transmission frame 44 and is configured as a frame body and two clamping blocks. The frame body is fixedly connected to the transmission frame 44, and the two clamping blocks are slidably connected to the frame body, with the sliding direction being the length direction of the frame body. Each clamping block is provided with a fixing screw for fixing the clamping block to the frame body. The screw is tightened on the clamping block and abuts against the frame body, thereby fixing the clamping block to the frame body through friction. The clamping method and structure of the frame body and the two clamping blocks are all prior art, so they will not be described in detail here.

[0044] Reference Figure 2 , Figure 3 and Figure 4 In the initial state, when the upper clamping frame 42 is directly above the lower clamping frame 43, the wire held by the upper clamping frame 42 and the lower clamping frame 43 is vertical. At this time, the tester can slide the upper adjusting frame 41 according to the length of the wire. When it is necessary to tilt the wire, and both the upper adjusting frame 41 and the lower adjusting frame 45 are locked, the pre-locking block 711 is inserted into the corresponding slot of the transmission frame 44. At this time, the transmission frame 44, through the sleeve frame 62, drives the corresponding adjusting frame 61 to slide relative to the corresponding upper adjusting frame 41, thereby causing the transmission frame 44 to shift.

[0045] Reference Figure 2 , Figure 3 and Figure 4 During this process, the contact position between the locking frame 72 and the abutment frame 73 changes, causing the locking frame 72 to gradually insert into the corresponding slot of the transmission frame 44 under the abutment action of the abutment frame 73, thereby achieving further locking between the transmission frame 44 and the sleeve frame 62. After the tilt angle of the transmission frame 44 is adjusted, the locking member 5 locks the upper adjusting frame 41 and the test table 2, thereby locking the transmission frame 44 and fixing the tilt angle of the wire held by the upper clamping frame 42 and the lower clamping frame 43.

[0046] Reference Figure 2 In this embodiment of the application, the test bench 2 may also be provided with an additional frame, and the frame and the lower adjustment frame 45 are at the same height. The frame may also be provided with a lower clamping frame 43 to facilitate clamping of the wire in the horizontal direction.

[0047] Reference Figure 1 , Figure 2 and Figure 5 The test mechanism 3 includes a mounting frame 31 and a combustion torch 32. The mounting frame 31 is slidably connected to the test bench 2 via a slide rail, and the extension line of the sliding direction passes through the opening on the body 1. An extension rod 33 is also provided on the mounting frame 31. The extension rod 33 is fixedly connected to the mounting frame 31, and one end extends towards the opening on the body 1.

[0048] Reference Figure 1 , Figure 2 and Figure 5 The mounting frame 31 is also equipped with a rotating mechanism 8, which includes a rotating frame 81 and a rotating assembly 82. The rotating frame 81 is rotatably connected to the top of the mounting frame 31 by a pin. The combustion torch 32 is fixedly installed on the top of the mounting frame 31. The bottom of the combustion torch 32 is also equipped with a pipe for connecting to the gas. The other end of the pipe extends to the outside of the machine body 1 and is used to connect to the gas source.

[0049] Reference Figure 1 , Figure 2 and Figure 5 The rotating assembly 82 includes a sliding frame 821, a drive frame 822, and a drive member 823. The sliding frame 821 is slidably connected to the mounting frame 31 via a sliding groove, and the sliding direction is parallel to the sliding direction of the mounting frame 31. One end of the mounting frame 31 extends to the side of the mounting frame 31 away from the upper door of the machine body 1, and is rotatably connected to one end of the drive frame 822 via a pin, while the other end is rotatably connected to the end of the rotating frame 81 via a pin.

[0050] Reference Figure 1 , Figure 2 and Figure 5 The driving component 823 includes an intermediate frame 8231 and a driving frame 8232. The intermediate frame 8231 is rotatably connected to one end of the extension rod 33 near the door of the machine body 1 via a pin, and is sleeved on the driving frame 8232 and slidably connected to the driving frame 8232, with the sliding direction set to the length direction of the driving frame 8232. The bottom end of the driving frame 8232 is rotatably connected to the sliding frame 821 via a pin.

[0051] Reference Figure 2 and Figure 5 The test bench 2 is also equipped with a retaining mechanism 9, which includes a retaining frame 91 and an unlocking component 92. One end of the retaining frame 91 is inserted into the extension rod 33 and slidably connected to it, with the sliding direction being vertical. The other end of the retaining frame 91 extends downward and, after passing through the sliding frame 821, is inserted into the test bench 2, thereby locking the mounting frame 31 and the sliding frame 821. Multiple slots are provided on the top of both the sliding frame 821 and the test bench 2 for inserting the retaining frame 91. Reference Figure 2 and Figure 5The unlocking component 92 includes a rotating rod 921 and a transmission rod 922. The middle part of the rotating rod 921 is rotatably connected to the intermediate frame 8231 via a pin, with one end extending upward and the other end extending downward at an angle. The bottom end of the rotating rod 921 is rotatably connected to one end of the transmission rod 922 via a pin, and the other end is rotatably connected to the retaining frame 91 via a pin. In this embodiment, a torsion spring may also be fitted on the rotating rod 921. One end of the torsion spring abuts against the extension rod 33, and the other end abuts against the rotating rod 921, so as to reset the rotating rod 921 through elastic force.

[0052] Reference Figure 2 and Figure 5 When the angle of the burner torch 32 needs to be adjusted, the tester holds the top of the drive frame 8232 and drives the rotating rod 921 to rotate. The rotating rod 921, through the transmission rod 922, causes the retaining frame 91 to slide, thereby causing the retaining frame 91 to slide upward and thus releasing the insertion of the sliding frame 821 into the test bench 2. Subsequently, the drive frame 8232 rotates, causing the sliding frame 821 to slide, and the sliding frame 821, through the drive frame 822, causes the rotating frame 81 to rotate, thereby causing the burner torch 32 to tilt.

[0053] Reference Figure 2 and Figure 5 After the adjustment is completed, the rotating rod 921 is released. At this time, the rotating rod 921 returns to its initial state under the elastic force of the torsion spring, thereby driving the retaining frame 91 to move downward through the transmission rod 922 and pass through the corresponding slot of the sliding frame 821 and be inserted into the corresponding slot of the test bench 2.

[0054] Reference Figure 1 and Figure 5 In this embodiment, the door of the machine body 1 is also provided with an opening, and a sealed glove is provided on the side of the opening inside the machine body 1, so that the tester can reach into the sealed glove from outside the machine body 1 and hold the extension rod 33 or the drive frame 8232 through the sealed glove. In this embodiment, the machine body 1 is also provided with a control mechanism, which includes a temperature sensor, an ultraviolet sensor, a timer, a camera, an oxygen analyzer, a smoke density meter, and a PLC controller, etc., to detect and regulate the test-related data inside the machine body 1. This control mechanism is prior art, so it will not be described in detail here.

[0055] The implementation principle of a wire burning tester according to an embodiment of this application is as follows: when it is necessary to tilt the wire, and both the upper adjustment frame 41 and the lower adjustment frame 45 are in the locked state, the pre-locking block 711 is inserted into the corresponding slot of the transmission frame 44. At this time, the transmission frame 44 drives the corresponding adjustment frame 61 to slide relative to the corresponding upper adjustment frame 41 through the sleeve frame 62, thereby causing the transmission frame 44 to shift.

[0056] During this process, the contact position between the locking frame 72 and the abutment frame 73 changes, causing the locking frame 72 to gradually insert into the corresponding slot of the transmission frame 44 under the abutment action of the abutment frame 73, thereby achieving further locking between the transmission frame 44 and the sleeve frame 62. After the tilt angle of the transmission frame 44 is adjusted, the locking member 5 locks the upper adjusting frame 41 and the test table 2, thereby locking the transmission frame 44 and fixing the tilt angle of the wire held by the upper clamping frame 42 and the lower clamping frame 43.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
