Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy cable tray technology, specifically to a device for testing the load-bearing performance of aluminum alloy cable trays. Background Technology

[0002] Aluminum alloy cable trays are cable supports made of aluminum alloy, primarily used for supporting and protecting cables. They are typically made from aluminum alloy sheets and are characterized by their lightweight, high strength, and corrosion resistance. The structure of an aluminum alloy cable tray includes trays, ladders, straight and bent sections, and supports, forming a continuous, rigid overall structure.

[0003] Existing tests on the load-bearing capacity of aluminum alloy cable trays mostly involve pressing down on the middle section with a simple press machine. This concentrates the stress point, fails to simulate real-world cables, and results in inaccurate test results. Furthermore, the cable trays need to be manually fixed during testing, which is inconsistent and time-consuming.

[0004] Therefore, it is necessary to design a practical and rapid testing device for the load-bearing performance of aluminum alloy cable trays. Utility Model Content

[0005] The purpose of this invention is to provide a load-bearing performance testing device for aluminum alloy cable trays, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a load-bearing performance testing device for aluminum alloy cable trays, comprising a base, a control plate fixedly installed on the top of the base, a control block slidably connected to the inner side of the control plate, a push plate provided at the bottom of the control block, a threaded rod connected to the inner side of the control plate by a bearing, the threaded rod being threadedly engaged with the control block, a spring provided on the outer side of the threaded rod, and a cable tray provided above the push plate.

[0007] According to the above technical solution, a transition block is provided on the outer side of the control board, a gear is provided on the inner side of the transition block, the gear is connected to a threaded rod, an upper rack is slidably connected to the inner side of the transition block, a lower rack is slidably connected to the inner side of the transition block, the upper rack and the lower rack are both meshed with the gear, a support plate is provided at the outer end of the upper rack and the lower rack, a clamp is provided on the rear side of the control board, and a clamping plate is provided at the clamping end of the clamp.

[0008] According to the above technical solution, a support frame is provided above the base, a first cylinder is provided at the bottom of the support frame, a detector is provided at the rod end of the first cylinder, and an arc-shaped tube is provided at the bottom of the detector.

[0009] According to the above technical solution, a second cylinder is provided above the base, a retainer is provided at the output end of the second cylinder, and a suction cup is provided on the inner side of the retainer.

[0010] According to the above technical solution, a telescopic device is provided above the support frame, a third cylinder is provided at the output end of the telescopic device, a buffer is provided at the rod end of the third cylinder, and a pressure plate is provided at the bottom of the buffer.

[0011] According to the above technical solution, a fixing plate is provided on the top of the base.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) By setting a push plate, the worker places the cable tray on the push plate and then pushes the cable tray backward. The cable tray will drive the push plate to move backward, thereby driving the control block to move backward and driving the threaded rod to rotate. At this time, the spring is compressed and then the cable tray is fixed. After the test is completed, the spring rebounds and the push plate is driven back to its original position by pushing the control block. When the control block moves backward and drives the threaded rod to rotate, it will drive the gear to rotate. At this time, the gear will drive the upper rack to slide to the right and drive the lower rack to slide to the left, thereby expanding the support plate outward, thereby fixing the inner side of the cable tray and preventing its displacement. At the same time, the sliding of the control block will trigger the clamp, and the clamp will drive the clamp plate to close, thereby fixing the cable tray from the outside. It works with the internal support plate to achieve automatic fixing and improve the fixing efficiency.

[0014] (2) By setting an arc tube, the bottom of the detector is set with an arc tube. The arc tube can simulate the bending caused by the cable tray after the cable applies pressure. The first cylinder drives the arc tube to descend and apply pressure to the cable tray. At this time, the detector will retract inward. After descending a fixed distance, the detection will begin. Assuming that the cable tray cannot withstand this downward pressure, the cable tray will bend. At this time, the detector will rebound. When it rebounds a certain distance, it means that the cable tray has been severely bent. Record the current result and complete the detection.

[0015] (3) After the cable tray is fixed at the end by the expansion joint, the third cylinder extends the air rod and fixes the cable tray by the pressure plate. The buffer buffers the cable tray. When the cable tray bends, the expansion joint will assist the cable tray to move inward to prevent the cable tray from breaking at the fixed point. Attached Figure Description

The worker places the cable tray 2 on the push plate 5 and then pushes the cable tray 2 backward. The cable tray 2 will drive the push plate 5 to move backward, thereby driving the control block 4 to move backward and driving the threaded rod 6 to rotate. At this time, the spring 7 is compressed by force, and then the cable tray 2 is fixed. After the test is completed, the spring 7 rebounds, and pushes the control block 4 to drive the push plate 5 back to its original position.

[0022] A transition block 8 is provided on the outer side of the control board 3, and a gear 9 is provided on the inner side of the transition block 8. The gear 9 is connected to the threaded rod 6.

A clamp 25 is provided on the rear side of the control board 3, and a clamping plate 26 is provided at the clamping end of the clamp 25. When the rear displacement causes the threaded rod 6 to rotate, it will drive the gear 9 to rotate. At this time, the gear 9 will drive the upper rack 10 to slide to the right and the lower rack 11 to slide to the left, thereby expanding the support plate 12 outward to fix the inner side of the cable tray 2 and prevent its displacement. At the same time, the sliding of the control block 4 will trigger the clamp 25. The clamp 25 will drive the clamp plate 26 to close, thereby fixing the cable tray 2 from the outside.

At this time, the detector 16 will retract inward. After descending a fixed distance, the detection begins. If the cable tray 2 cannot withstand this downward pressure, the cable tray 2 will bend. At this time, the detector 16 will rebound. When it rebounds a certain distance, it means that the cable tray 2 has been severely bent. The current result is recorded, and the detection is completed.

[0024] A second cylinder 17 is provided above the base 1. A retainer 18 is provided at the output end of the second cylinder 17. A suction cup 19 is provided on the inner side of the retainer 18.
