For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] A test bench for bus duct bending test, such as Figures 1 to 6 As shown, it includes a base 1 and a bearing seat 2 arranged on the base 1, wherein at least two bearing seats 2 are arranged at intervals along the length direction of the base 1, and a support member 5 for supporting the bus duct is provided above each bearing seat 2, and the support member 5 is detachably installed on the bearing seat 2; a rotatable support frame 3 is provided at a position corresponding to the support member 5 on the bearing seat 2, a rolling member 4 is rotatably installed on one end of the support frame 3, and the other end is rotatably installed on the bearing seat 2, and a positioning component for limiting the support frame 3 is provided on the bearing seat 2.

[0036] Exemplarily, the bearing seat 2 can be fixed on the base 1 by bolts, and multiple fixing positions of the bearing seat 2 can be set on the base 1, so that the operator can adjust the number of bearing seats 2 according to the actual length of the bus duct, so that the bus duct can move under the guidance of the rolling elements 4 on the multiple bearing seats 2, which reduces the difficulty of moving and adjusting the bus duct and is conducive to improving the testing efficiency of the bus duct. Those skilled in the art can also choose other ways to install and fix the bearing seat 2 according to actual needs to achieve a stable setting of the bearing seat 2 on the base 1, which will not be repeated here.

[0037] In addition, this test bench can also be used in conjunction with a conveyor belt. After the bus duct is moved to the carrier frame using the conveyor belt, the bus duct is guided by the rolling element 4 on the support frame 3 until the bus duct moves to the test position, which makes operation easier.

[0038] In actual application, two, three or more bearing seats 2 can be arranged at intervals, wherein the bearing seats 2 at the left and right ends of the base 1 can be provided with support members 5, and other bearing seats 2 do not need to be provided with support members 5. When the bus duct needs to be moved and loaded and unloaded, the support frame 3 can be rotated first, and the rolling member 4 on the support frame 3 is located above the supporting member 5. At this time, the bus duct can be rolled and supported by only the rolling member 4 on the support frame 3, so that the bus duct can be conveniently moved and adjusted.

[0039] By setting at least two bearing seats 2 at intervals, the support members 5 on the two bearing seats 2 can be used to support and test the bus duct. When the bus duct is supported by the support members 5 for bending resistance test, the operator can first release the limit of the support frame 3 by the positioning component, and then rotate the support frame 3 to release the contact between the rolling member 4 and the bus duct, and only use the support members 5 on the bearing seats 2 at the left and right ends of the base 1 to support the bus duct. Those skilled in the art can also select the bearing seats 2 at appropriate positions to install the support members 5 according to the actual length of the bus duct to support the bus duct during the test, which will not be repeated here. By setting multiple bearing seats 2, the applicability of this test bench to bus ducts of different lengths is improved.

[0040] Optionally, two support frames 3 are provided on the left and right sides of the corresponding support member 5, and the two support frames 3 are arranged in an inverted "eight" shape. Exemplarily, the rolling member 4 can be a roller, and the roller can be rotatably installed on the support frame 3 through a rotating shaft, and the support frame 3 is provided with an axial hole that cooperates with the rotating shaft. By arranging two support frames 3 in an inverted "eight" shape, the rolling members 4 on the two support frames 3 can better guide the bus duct, and the two support frames 3 are also conducive to improving the stability of the bus duct during movement.

[0041] By arranging two support frames 3 in an inverted "eight" shape, when the operator releases the limit of the positioning assembly on the support frame 3, the support frame 3 can be quickly rotated downward and opened under the action of its own gravity and the pressure of the bus duct, so that the support member 5 can quickly support the bus duct. The bus duct is not easy to change position during the falling process, which is conducive to avoiding secondary adjustment of the bus duct, thereby improving the testing efficiency of the bus duct.

[0042] Optionally, the bearing seat 2 is provided with an assembly groove 14 for accommodating the support frame 3, and a chamfered portion capable of cooperating with the support frame 3 is provided at a position corresponding to the assembly groove 14 above the bearing seat 2. Exemplarily, the support frame 3 can also be rotatably mounted on the bearing seat 2 via a rotating shaft, and a shaft hole cooperating with the rotating shaft is provided at a position corresponding to the assembly groove 14 on the bearing seat 2, and the shaft hole is connected to the assembly groove 14. By providing the assembly groove 14 and providing the chamfered portion on the side wall of the assembly groove 14, it is beneficial to improve the stability of the support frame 3 when supporting the bus duct, and prevent the support frame 3 from tilting or moving.

[0043] Optionally, a magnetic block 19 is provided on the support frame 3, and a magnetic portion 13 capable of cooperating with the magnetic block 19 is provided at a position corresponding to the assembly groove 14 on the bearing seat 2. Exemplarily, the magnetic block 19 can be a magnet, and the magnet can be mounted and fixed on the support frame 3 by adhesive or screws, and a groove for mounting the magnet is provided on the support frame 3. At the same time, the bearing seat 2 can also be made of steel to form a magnetic portion 13 capable of cooperating with the magnetic block 19. By providing a magnetic block 19 on the support frame 3 and cooperating with the magnetic block 19 and the magnetic portion 13, the initial positioning of the support frame 3 can be achieved, thereby facilitating subsequent operators to further limit the support frame 3 using the positioning assembly, which helps to reduce the operating difficulty of the operator.

[0044] In addition, by using the cooperation of the magnetic block 19 and the magnetic part 13, when the operator releases the limit of the support frame 3 by the positioning component, the magnetic force between the magnetic block 19 and the magnetic part 13 also helps to slow down the rotation speed of the support frame 3 during the process of the bus duct pressing down to drive the support frame 3 to rotate, thereby helping to further reduce the possibility of the bus duct being difficult to change position during the falling process.

[0045] Optionally, the positioning assembly includes a positioning member 6, the positioning member 6 is vertically slidably mounted on the bearing seat 2, the positioning member 6 is provided with a positioning groove 20, the support frame 3 is provided with a positioning column 8 that can cooperate with the positioning groove 20, and the positioning column 8 is fixed to the support frame 3. Exemplarily, the bearing seat 2 is provided with a positioning shaft 11, the positioning shaft 11 is fixed to the bearing seat 2, the positioning member 6 is provided with a strip hole 10 that cooperates with the positioning shaft 11, one end of the positioning shaft 11 passing through the strip hole 10 is provided with a detachable stopper 7, and the other end is arranged on the bearing seat 2.

[0046] Specifically, the positioning shaft 11 is a cylindrical structural member, and the limiting member 7 and the positioning shaft 11 can be connected by threads. Those skilled in the art can also choose other suitable methods to install the limiting member 7 according to actual needs to achieve detachable installation of the limiting member 7 on the positioning shaft 11, which will not be repeated here. By setting the limiting member 7, the limiting member 7 can play a good limiting role on the positioning member 6, prevent the positioning member 6 from falling off the positioning shaft 11, ensure that the positioning groove 20 on the positioning member 6 can be stably matched with the positioning column 8, and achieve the limiting of the support frame 3.

[0047] In actual application, the positioning member 6 includes a horizontal end and a vertical end, the positioning groove 20 is provided on the horizontal end of the positioning member 6, the strip hole 10 is provided on the vertical end of the positioning member 6, and the horizontal end and the vertical end of the positioning member 6 are connected by a reinforcing plate 21. Exemplarily, the positioning member 6 is a T-shaped structural member, and the positioning grooves 20 are provided on both the left and right sides of the horizontal end of the positioning member 6, and two reinforcing plates 21 are provided correspondingly, and each reinforcing plate 21 is fixed to the horizontal end of the positioning member 6 at one end and to the vertical end of the positioning member 6 at the other end.

[0048] By adopting the T-shaped positioning member 6, one positioning member 6 can limit the two support frames 3, which is helpful to reduce the difficulty of operation for operators. Specifically, when the operator needs to release the positioning member 6 from limiting the support frame 3, he only needs to move the positioning member 6 upward so that the positioning column 8 moves out of the positioning groove 20, which is easy to operate.

[0049] Optionally, the support member 5 is provided with a connection portion 17 at one end facing the bearing seat 2, and a conical end portion 18 at the other end, and the bearing seat 2 is provided with a receiving groove 12 that cooperates with the connection portion 17. Exemplarily, a detachable fixing bolt 9 is provided at a position corresponding to the receiving groove 12 on the bearing seat 2, and a bolt hole 16 that cooperates with the fixing bolt 9 is provided on the connection portion 17, and a mounting hole 15 that cooperates with the fixing bolt 9 is provided on the bearing seat 2, and the mounting hole 15 is connected to the receiving groove 12. By using the fixing bolt 9 to install and fix the support member 5, it can be ensured that the support member 5 is stably installed and fixed on the bearing seat 2, so that the support member 5 can stably support the bus duct during the test. Among them, by providing the conical end portion 18 on the support member 5, it is beneficial to reduce the contact area between the support member 5 and the bus duct, and it is convenient to perform bending resistance testing on the bus duct.

[0050] Optionally, the support member 5 is a T-shaped structural member, the conical end portion 18 is arranged on the horizontal end of the support member 5, and the connecting portion 17 is arranged on the vertical end of the support member 5. Exemplarily, by adopting the support member 5 with a T-shaped structure, the structural strength of the support member 5 is improved.

[0051] The utility model discloses a test bench for bus duct bending resistance test, which has the advantages of simple structure, easy use and high applicability. By arranging at least two bearing seats at intervals, not only can the support members on the bearing seats be used to support and test the bus duct, but also the rolling members on the support frame can be used to guide the bus duct, which reduces the difficulty of moving and adjusting the bus duct, and is conducive to improving the efficiency of the bus duct bending resistance test.
