[0038] The second locking member 2 is provided with a plurality of friction blocks.
[0039] It also includes a locking block 102 and a first driving member 103; a fixing groove 1002 is opened on each semicircular ring constituting the first locking member 1; a plurality of annularly distributed first driving members 103 are fixedly connected to the first locking member 1, and the first driving member 103 is an electric push rod; all the first driving members 103 are located in the fixing groove 1002; and a locking block 102 is fixedly connected to the output end of each first driving member 103.
[0040] Each locking block 102 is provided with a plurality of anti-slip grooves to enhance the clamping effect of the locking block 102 on the cable 100 .
[0041] When performing a tensile test on the cable 100 on the AC / DC charging pile 200 put into use in the external environment, firstly rotate and open the first locking member 1 and the second locking member 2 of the present invention, and then fix the first locking member 1 and the second locking member 2 on the charging pile 200 to provide charging services for the electric vehicle. Before fixing, first straighten the cable 100 between the first locking member 1 and the second locking member 2, and then connect the air pump through the ventilation pipe 3001 to pump gas into the pneumatic push rod 3, so that the output end of the pneumatic push rod 3 moves in the direction of the second locking member 2, driving the second locking member 2 away from the first locking member 1, thereby completing the tensile performance test of the cable 100. In order to truly simulate the scene when the charging pile 200 charges the electric vehicle and the cable 100 is stretched by manually holding the charging gun 300, the present invention is provided with Figure 4As shown in the universal joint 4, the pneumatic push rod 3 can rotate in different directions under the action of the universal joint 4, and then the second locking member 2 and the cable 100 fixed on the second locking member 2 are driven to rotate in different directions through the pneumatic push rod 3, so as to simulate the scene of manually holding the charging gun 300 to drive the cable 100 to stretch, and after the rotation of the cable 100 is completed, the limiting rods 303 on the first rotating member 4001 and the second rotating member 4003 are respectively driven to slide downward along the limiting slide groove 30101, and embedded in the grooves provided on the adjacent limiting blocks 302, so as to limit the rotation of the cross shaft 4002 and the first rotating member 4001, so as to complete the universal joint. The locking of section 4 allows the cable 100 to be confined in a specific direction, and then the output end of the pneumatic push rod 3 drives the second locking piece 2 and the cable 100 fixed by the second locking piece 2 to move in the direction of the second locking piece 2, and the tensile performance of the cable 100 in this direction is tested, so as to realize the tensile performance of the cable 100 under the real simulation of the charging state of the manual handheld charging gun 300. It should be noted that the maximum tensile strength of the present invention is within the tensile strength of the cable 100 in normal use. If the cable 100 is deformed under the tensile performance test of the present invention, the cable 100 is severely worn and cannot be put into use anymore, and needs to be replaced.
[0042] In order to truly understand whether the tensile performance of the cable 100 is affected by the connection method with the charging pile 200 and the charging gun 300, when testing the tensile performance of the cable 100, tensile tests are performed on the connection part between the cable 100 and the charging pile 200, the middle part of the cable 100, and the connection part between the cable 100 and the charging gun 300. When testing the connection part between the cable 100 and the charging pile 200, if Figure 2 As shown, when the first locking member 1 and the second locking member 2 fix the cable 100, the first locking member 1 is attached to the charging pile 200 and fixed to the cable 100, and then one end of the fixing rope 101 is fixed to the through hole 1001, and then the charging pile 200 is tied up with the fixing rope 101, and the other end of the fixing rope 101 is fixed to the through hole 1001, so that the first locking member 1 is fixed to the charging pile 200, which is convenient for detecting the tensile performance of the connection part between the cable 100 and the charging pile 200; when detecting the connection part between the cable 100 and the charging gun 300, as shown Figure 8 As shown, in order to be able to fix the present invention on the charging gun 300, the locking block 102 is driven to adapt to the size of the charging gun 300 by driving the output end of the first driving member 103, so that the first locking member 1 can be fixed on the charging gun 300, and the tensile performance test of the cable 100 at the connection between the cable 100 and the charging gun 300 is completed, and the tensile performance test result is used to determine whether it is necessary to optimize the cable 100 or the connection method between the cable 100 and the charging gun 300, or whether it is necessary to optimize the connection method between the cable 100 and the charging gun 300 when the charging pile 200 is subsequently manufactured.
[0043] Example 2
[0044] On the basis of Example 1, Figure 1 and Figure 9-12 As shown, it includes a support 201, a first electric slider 204, a fixed bracket 205, a second driving member 206, a push plate 207, a limit pin 208 and a cutting assembly; the pneumatic push rod 3 is provided with a support 201; four sliding grooves 20101 are provided on the support 201; four limiting grooves 20102 are provided on the support 201; two adjacent sliding grooves 20101 and limiting grooves 20102 are connected to each other; two sliding grooves 20101 are provided with a first electric slider 204; each of the first A fixed bracket 205 is fixedly connected to an electric slider 204; a second driving member 206 is fixedly connected to each fixed bracket 205, and the second driving member 206 is an electric push rod; a push plate 207 is fixedly connected to the output end of each second driving member 206; the two push plates 207 together form a circular ring, and each push plate 207 is provided with a cutting groove 20701; a cutting component is provided on one of the cutting grooves 20701; each first electric slider 204 can be detachably connected with a limit pin 208.
[0045] It also includes a fixing block 202 and a fixing rod 203 ; the fixed end of the pneumatic push rod 3 is fixedly connected to the two fixing blocks 202 ; the fixing block 202 is plugged with the fixing rod 203 ; the support 201 is fixed to the pneumatic push rod 3 through the fixing rod 203 .
[0046] The cutting assembly includes a second electric slider 209, a third driving member 20901 and a cutting knife 20902; the second electric slider 209 is slidably connected to one of the cutting slide grooves 20701; the third driving member 20901 is fixedly connected to the second electric slider 209, and the third driving member 20901 is an electric push rod; the cutting knife 20902 is fixedly connected to the output end of the third driving member 20901.
[0047] The inner annular surface formed by the two push plates 207 is coated with an anti-slip coating, which makes it easier for the push plates 207 to fix the bellows 400 and cut the bellows 400.
[0048] A testing method for an AC / DC charging pile anti-corrosion cable performance testing device comprises the following steps:
[0049] Step 1: Rotate and open the first locking member 1 and the second locking member 2 of the AC / DC charging pile anti-corrosion cable performance test device, and fix and clamp the cable 100 to be tested through the first locking member 1 and the second locking member 2;
[0050] Step 2: During the test, the state of the cable 100 in a real charging scenario is simulated by the universal joint 4, and gas is pumped into the vent pipe 3001 to drive the output end of the pneumatic push rod 3 to drive the second locking member 2 to drive the cable 100 to perform a tensile test;
[0051] Step 3: After completing the tensile performance test of the cable 100 in this area, the first locking member 1 and the second locking member 2 are rotated to release the clamping of the cable 100, and the clamping area of the cable 100 is switched to complete the tensile performance test of different areas of the cable 100;
[0052] Step 4: When the cable 100 wrapped with the corrugated tube 400 is detected, the corrugated tube 400 is cut by a cutting assembly. After the corrugated tube 400 is cut, the cable 100 is exposed, and the tensile performance test of the cable 100 is completed.
[0053] When manufacturing the charging pile 200, in order to extend the service life of the cable 100, some manufacturers will sheath a corrugated tube 400 on the outside of the cable 100. In order to prevent the corrugated tube 400 sheathed on the outside of the cable 100 from affecting the tensile performance test of the cable 100 of the present invention, before testing the tensile performance, the present invention installs the support 201 on the pneumatic push rod 3 through the fixing rod 203, installs the first electric slider 204 on the sliding groove 20101, and passes the limiting pin 208 through the limiting groove 20102 to fix the first electric slider 204 so that it is confined in the sliding groove 20101. The push plate 207 is fixed to the support 201 through the installation of the first electric slider 204. The two push plates 207 are installed on the same side and can form a complete ring when they are in contact with each other. After the installation is completed, open the first locking member 1 and the second locking member 2, as shown in FIG. Fig. 9As shown, it is buckled on the corrugated tube 400 on the surface of the cable 100 to be tested. Due to the influence of the diameter of the corrugated tube 400, the first locking member 1 and the second locking member 2 cannot be completely buckled, but the corrugated tube 400 can be initially fixed to prevent it from moving significantly. The first electric slider 204 slides on the sliding groove 20101, so that the first electric slider 204 drives the fixed bracket 205, the second driving member 206 and the push plate 207 to move to the trough of the corrugated tube 400, and drives the output end of the second driving member 206 to move toward the corrugated tube 400, so that the two push plates 207 are close to and buckled on the trough of the corrugated tube 400, and drives the first electric slider 204 to move in the direction close to the second locking member 2, so that the first electric slider 204 The fixing bracket 205, the second driving member 206 and the pushing plate 207 are driven to move together, thereby fixing the corrugated tube 400 and expanding its wave crest outward, away from the internal cable 100, to avoid damaging the cable 100 when the corrugated tube 400 is subsequently cut, and the output end of the third driving member 20901 is driven to move outward, driving the cutting knife 20902 to move outward. After the cutting knife 20902 contacts the corrugated tube 400 and cuts the corrugated tube 400, the second electric slider 209 is driven to slide along the cutting slot 20701, driving the cutting knife 20902 to completely cut the corrugated tube 400. After the cutting is completed, the output end of the third driving member 20901 is driven to move toward the cutting slot 20701, so that the cutting knife 20902 returns to its original position. If only one end needs to be fixed on the cable 100, the staff pushes the cut corrugated tube 400 to both sides to expose the internal cable 100, and fixes the cable 100 through the first locking member 1 or the second locking member 2. If both ends need to be fixed on the cable 100, pull out the limit pin 208, cancel the restriction on the first electric slider 204, remove the push plate 207, install it on the other side where it needs to be fixed, and cut the corrugated tube 400 in the same way. After the cutting of the corrugated tube 400 is completed, pull out the fixing rod 203, remove the support 201 and its parts, and complete the tensile performance test of the cable 100 according to the operation of the first embodiment. After the cable 100 passes the tensile performance test, the cut corrugated tube 400 is manually bonded with tape to restore its protective function.
[0054] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
