Description

Technical Field

[0001] The utility model relates to the technical field of load testing, in particular to a wire trough load testing device. Background Art

[0002] A cable trough, also known as a wiring trough, wiring trough, or cable duct, is an electrical tool used to install and manage wires and cables. Typically made of plastic or metal, it offers excellent insulation, flame retardancy, and impact resistance. Its primary function is to organize and secure power cables, data cables, and other wires to the wall or ceiling in a standardized manner, protecting the wiring, enhancing the aesthetic, and preventing fire hazards.

[0003] To ensure the quality and safety of cable ducts during production, pressure load tests are usually performed on them. Pressure load tests simulate the various external forces that the cable ducts will withstand in actual use, such as the weight of the wires and the mechanical stress during installation. This allows us to verify whether the structural strength of the cable duct is sufficient to avoid damage or deformation during use.

[0004] However, when testing the wire trough, the existing pressure load test device is usually fixed on a fixture. When load testing is to be performed on different sides of the wire trough, the fixture needs to be removed and repositioned, which is a more troublesome operation. Utility Model Content

[0005] To address the problems in the prior art, a load test device for a wire trough is proposed. This device is equipped with a shifting mechanism. During a load test, the motor, dial, rotating shaft, and sheave cooperate to drive two pressure plates to intermittently move the wire trough in a quarter circle. This allows the side of the wire trough facing the pressure plate to be changed, facilitating load testing on different sides of the wire trough and improving overall operational convenience.

[0006] The utility model provides a wire trough load test device, comprising

[0007] A bottom cabinet is symmetrically provided with a vertical frame, a top plate is provided on the top of the vertical frame, an electric push rod is installed at the bottom of the top plate, and a pressure plate is connected to the piston end of the electric push rod;

[0008] There are two sets of connecting frames, one on each side of the two sets of vertical frames, one end of which is rotatably connected to a horizontal shaft through a bearing, one end of which is connected to a connecting plate, and a limiting member for limiting the position of the wire trough is provided between the two connecting plates; and

[0009] The shifting mechanism is arranged on the connecting frame and is used to cooperate with the limiting member to drive the wire trough to change position.

[0010] Preferably, the limiting member includes a square rod, a compression spring and a pressure plate.

A compression spring is connected between the pressure plate and the connecting plates, and the compression spring is sleeved on the square rod.

[0011] Preferably, slots are provided on opposite sides of the two pressure plates for inserting the two ends of the power supply line duct.

[0012] Preferably, an industrial camera is also installed at the bottom of the top plate, which is used to photograph the surface status of the wire trough after the load test.

[0013] Preferably, the shifting mechanism includes a motor, a dial, a rotating shaft and a groove wheel. The rotating shaft is rotatably connected to the side of the corresponding connecting frame, one end of which is connected to the horizontal axis, and the other end is connected to the groove wheel. The motor is installed on the side of the connecting frame away from the groove wheel, and its output end passes through the connecting frame and is connected to the dial that cooperates with the groove wheel.

[0014] Preferably, four groups of concave locking arcs are evenly arranged on the outer side of the groove wheel in a circumferential manner, and radial grooves are arranged between two adjacent groups of concave locking arcs.

DETAILED DESCRIPTION

[0021] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0022] Example 1

[0023] like Figure 1-Figure 3 As shown, the utility model proposes a wire trough load test device, which includes a base cabinet 1, a connecting frame 6 and a transposition mechanism. The base cabinet 1 is symmetrically provided with a vertical frame 2, a top plate 3 is provided on the top of the vertical frame 2, and an electric push rod 4 is installed at the bottom of the top plate 3. The piston end of the electric push rod 4 is connected to a pressure plate 5. There are two groups of connecting frames 6, which are respectively located on one side of the two groups of vertical frames 2. One end of the connecting frame 6 is rotatably connected to a horizontal axis 7 through a bearing, and one end of the horizontal axis 7 is connected to a connecting plate 8. A limiting piece for limiting the wire trough is provided between the two connecting plates 8, and a transposition mechanism is provided on the corresponding connecting frame 6, which is used to cooperate with the limiting piece to drive the wire trough to change position.

[0024] like Figure 1 As shown, the limiting member includes a square rod 9, a compression spring 10 and a pressure plate 11. The square rod 9 is connected between the two connecting plates 8, and the pressure plate 11 is symmetrically slidably arranged on it. The compression spring 10 is connected between the pressure plate 11 and the connecting plate 8, and the compression spring 10 is sleeved on the square rod 9.

[0025] like Figure 2 As shown, slots 12 are provided on opposite sides of the two pressing plates 11 for inserting two ends of the power supply line duct.

[0026] During use, one side of the pressure plate 11 is manually moved to make the pressure plate 11 slide along the square rod 9. During the sliding process, it squeezes the compression spring 10 so that the distance between the two pressure plates 11 is greater than the length of the wire trough. Then, the two ends of the wire trough to be loaded are inserted into the slot 12. Under the elastic restoring force of the compression spring 10, it is clamped between the two pressure plates 11. Then, the pressure plate 5 is driven down by the electric push rod 4 so that the pressure plate 5 is in hard contact with the wire trough to observe whether it is damaged or deformed.

[0027] like Figure 1As shown, an industrial camera 13 is also installed at the bottom of the top plate 3, which is used to photograph the surface status of the wire trough after the load test.

[0028] Example 2

[0029] like Figure 1-Figure 3 As shown, the utility model proposes a wire trough load test device. On the basis of the above embodiment, this embodiment also records in detail the specific components of the transposition mechanism and its specific transposition method for the wire trough.

[0030] like Figure 3 As shown, the shifting mechanism includes a motor 14, a dial 15, a rotating shaft 16 and a groove wheel 17. The rotating shaft 16 is rotatably connected to the side of the corresponding connecting frame 6, one end of which is connected to the horizontal axis 7, and the other end is connected to the groove wheel 17. The motor 14 is installed on the side of the connecting frame 6 away from the groove wheel 17, and its output end passes through the connecting frame 6 and is connected to the dial 15 that cooperates with the groove wheel 17.

[0031] like Figure 3 As shown, four groups of concave locking arcs 18 are evenly arranged on the outer side of the groove wheel 17 in a circular shape. The concave locking arcs 18 are limitedly matched with the outer arc of the dial 15. A radial groove 19 is provided on the groove wheel 17 between two adjacent groups of concave locking arcs 18. A clearance groove 20 is provided on the outer side of the dial 15. A strip plate 21 is provided in the middle of the clearance groove 20. A pin shaft 22 is provided on the strip plate 21. The pin shaft 22 extends into the radial groove 19.

[0032] During use, the motor 14 drives the dial 15 to rotate. During the rotation of the dial 15, its outer arc clamps the concave locking arc 18 of the groove wheel 17, so that the groove wheel 17 and the rotating shaft 16 remain stationary. When the dial 15 rotates to the point where the pin 22 on it is driven by the strip plate 21 to enter the radial groove 19 of the groove wheel 17, the limiting effect of the concave locking arc 18 of the groove wheel 17 is released under the action of the give way groove 20, that is, the groove wheel 17 rotates a quarter of an inch under the action of the pin 22. One circumference, when the dial 15 rotates to drive the pin 22 out of the radial groove 19, the groove wheel 17 is again clamped by the outer arc of the dial 15 under the action of the concave locking arc 18, so that during the test, the groove wheel 17 is driven to make a quarter-circle intermittent rotation. During the rotation process, the groove wheel 17 drives the horizontal axis 7 to rotate through the rotating shaft 16, and the horizontal axis 7 drives the pressure plate 11 to rotate synchronously through the connecting plate 8 and the square rod 9, thereby changing the position of the wire trough so that different sides thereof are facing the pressure plate 5.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
