[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0028] The cable tray performance test device according to the embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the cable tray performance test device of the embodiment of the utility model may include a base plate 1, a clamping mechanism 2, a plurality of columns 3, a plurality of beams 4 and an impact mechanism 5.

[0030] The clamping mechanism 2 is disposed on the base plate 1 , and the clamping mechanism 2 may include two clamping plates 21 , a plurality of clamping blocks 22 , a plurality of tightening assemblies 23 , two driving assemblies 26 and a plurality of connecting assemblies 27 .

[0031] It should be noted that the clamping mechanism 2 is capable of clamping both sides and both ends of the cable tray, thereby increasing the clamping stability.

[0032] A plurality of first grooves 24 are formed on the bottom plate 1 .

[0033] It can be understood that the first groove 24 can enable the clamping plates 21 to move toward each other so as to clamp the two sides of the cable tray.

[0034] Two drive assemblies 26 are installed on both sides of the interior of the base plate 1 .

[0035] It should be noted that the driving assembly 26 is used to control the two clamping plates 21 to move toward each other.

[0036] In one embodiment of the present invention, Figure 2 As shown, the driving assembly 26 may include a rotary motor 261 , a threaded column 262 and a bearing seat 263 .

[0037] Among them, since the rotating motor 261 is installed on one side of the inner wall of the bottom plate 1, the bearing seat 263 is installed on the other side of the inner wall of the bottom plate 1, the threaded column 262 is connected to the output shaft of the rotating motor 261, and the other end of the threaded column 262 is installed on the bearing seat 263. Therefore, when the rotating motor 261 rotates, the two ends of the threaded column 262 can be kept between the rotating motor 261 and the bearing seat 263, ensuring the stability of the rotation of the threaded column 262.

[0038] The threaded column 262 is provided with a first thread 2621 and a second thread 2622 with opposite rotation directions.

[0039] Two connecting components 27 are mounted on the driving component 26 , and the connecting components 27 pass through the first slot 24 and are connected to the clamping plate 21 .

[0040] In one embodiment of the present invention, Figure 2 As shown, the connection assembly 27 may include a sleeve 271 and a mounting post 272 .

[0041] The sleeves 271 are respectively installed on both sides of the threaded column 262 .

[0042] It should be noted that in order for the threaded column 262 to drive the sleeve 271 installed on its surface to rotate when rotating, the rotation direction of the rotating motor 261 should be the same as the thread direction of the first thread 2621, so that the sleeve 271 on the surface of the threaded column 262 can move toward each other during rotation.

[0043] Since the mounting column 272 is installed on the sleeve 271, the mounting column 272 passes through the first groove 24 and is connected to the clamping plate 21, when the sleeve 271 moves toward each other, the mounting column 272 connected to the sleeve 271 and the clamping plate 21 connected to the mounting column 272 can be made close to each other, thereby clamping the cable tray body 10 placed therein.

[0044] Furthermore, in order to make the cable tray clamped more stably, the device fixes the sides of both ends of the cable tray to prevent the cable tray body 10 from being displaced between the two clamping plates 21 .

[0045] The clamping plate 21 is provided with a second groove 25 .

[0046] Tightening assemblies 23 are installed on both side ends of the clamping plate 21 , and the tightening assemblies 23 pass through the second groove 25 and are connected to the clamping block 22 .

[0047] Specifically, the tightening assembly 23 may include a connecting rod 231 , a tightening nut 232 and a connecting column 233 .

[0048] The connecting rod 231 is installed on one side of the clamping block 22 , the connecting column 233 passes through the second groove 25 and is connected to the connecting rod 231 , and the tightening nut 232 is installed on the connecting column 233 .

[0049] It should be noted that a thread is provided on the connecting column 233, and the nut matches the thread. When the cable tray is further firmly clamped, on the basis of the stable clamping of the two sides of the cable tray by the clamping plate 21, the connecting column 233 is passed through the second groove 25, and the inner side of the clamping block 22 is brought close to the side of the cable tray body 10, and then the connecting column 233 is tightened by tightening the nut 232.

[0050] When testing the performance of the cable tray, since the cable tray has different lengths, when fixing the outer edge of the cable tray body 10, the distance between the clamping blocks 22 on the same clamping plate can be adjusted by sliding on the second groove 25, and then fixed by nuts.

[0051] It should be noted that in order to prevent the clamping block 22 from falling out of the second groove 25 , the diameter of the nut should be greater than the width of the second groove 25 .

[0052] A plurality of columns 3 are installed on both sides of the base plate 1 , and a plurality of cross beams 4 are installed between the plurality of columns 3 .

[0053] In order to test the impact resistance of the cable tray, the impact mechanism 5 is installed at the bottom of the beam 4. After the cable tray is clamped, the impact mechanism 5 can be used to impact the cable tray body 10, so as to test its impact resistance.

[0054] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the impact mechanism 5 may include a housing 51 , a plurality of push rod motors 52 and a hammer plate 53 .

[0055] Among them, a plurality of push rod motors 52 are installed on the inner wall of the housing 51, and the hammer plate 53 is connected to the output shafts of the plurality of push rod motors 52. It should be noted that the push rod motor 52 drives the hammer plate 53 to move up and down, so as to hit the cable tray body 10, thereby realizing the test of the cable tray body 10.

[0056] Specifically, when the cable tray body 10 needs to be tested, the cable tray is placed between the two clamping plates 21, and the rotating motor 261 is turned on, so that the rotating motor 261 drives the threaded column 262 to rotate, and then the sleeve 271 installed on the surface of the threaded column 262 moves. When the sleeve 271 moves, it successively drives the installation column 272 and the clamping plate 21 to move, thereby achieving the clamping of the outer wall of the cable tray body 10.

[0057] Afterwards, according to the length of the cable tray body 10, the connecting rod 231 is moved on the inner wall of the second groove 25, so that the connecting rod 231 drives the connecting column 233, and then drives the clamping block 22 to move inside the first groove 24. When the clamping block 22 is close to the outer side of the cable tray body 10, the two end sides of the cable tray body 10 are fitted with the clamping block 22, and then the tightening nut 232 is rotated to clamp the four sides of the cable tray.

[0058] When the clamping is completed, the push rod motor 52 drives the hammer plate 53 to hammer toward the surface of the cable tray body 10 to test the performance of the cable tray body 10 .

[0059] In summary, the cable tray performance testing device of the embodiment of the utility model can ensure the stability of the cable tray clamping when testing the cable tray, avoid the movement of the cable tray during the test, and make the test result more accurate.
