[0003] The traditional experimental method is usually to implement telescopic testing in the free state of the lifting cylinder. However, this testing method is significantly different from the actual application conditions. For example, in the testing of the lifting cylinder of some heavy machinery, the traditional method cannot simulate the actual counterweight conditions, resulting in the test results not accurately reflecting the actual matching conditions between the cylinder and the piston rod, which in turn has an adverse effect on the test effect. In view of this, a lifting cylinder reciprocating test bench is provided to solve the above technical problems. Utility Model Content

[0004] In view of the problem that the traditional method of monitoring the lifting cylinder in the prior art cannot simulate the actual counterweight condition, resulting in the detection result cannot accurately reflect the actual matching situation of the cylinder barrel and the piston rod, which is easy to have an adverse effect on the detection effect, the utility model provides a lifting cylinder reciprocating test bench, which can rotate the lifting cylinder and install it between the base and the triangular counterweight block by means of an adapter. When the lifting cylinder reciprocates and retracts, it can drive the triangular counterweight block to flip between the two triangular support plates, thereby simulating the actual working conditions of the lifting cylinder, which can reflect the actual matching situation of the cylinder barrel and the piston rod, making the experimental data closer to the actual use situation, ensuring the product quality and safety performance of the lifting cylinder, and effectively resolving the problem that the traditional mode of monitoring the lifting cylinder in the prior art cannot simulate the actual counterweight condition, and avoiding the problem that the detection result cannot accurately reflect the actual matching situation of the cylinder barrel and the piston rod, which has an adverse effect on the detection effect. The specific technical scheme is as follows:

[0005] A lifting cylinder reciprocating test bench comprises a base and a lifting cylinder body, both ends of the lifting cylinder body are fixedly installed with a hinged part with a hole, and is characterized in that two triangular support plates are symmetrically fixedly installed on the upper surface of the base, a triangular counterweight block is rotatably installed between the two triangular support plates, a support block is fixedly installed on the right side of the upper surface of the base, and the support block is used to support the bottom of the triangular counterweight block, and the left surface of the triangular counterweight block and the left side of the upper surface of the base are fixedly installed with an adapter device, and the two adapter devices are rotatably connected to the corresponding hinged parts with holes respectively.

[0006] In the above technical scheme, the two adapter devices each include a fixing plate, and the two fixing plates are respectively welded and fixed to the upper surface of the base and the left surface of the triangular counterweight block, and two fixing blocks are fixedly installed on one side of the fixing plate close to the hinged part with a hole, and a through opening is penetrated through the outer surface of the fixing block, and an adapter column is inserted and installed between the two through openings, the hinged part with a hole is located between the two corresponding fixed blocks, and the hinged part with a hole is rotatably connected to the adapter column, and a pin hole is penetrated through the front end of the adapter column, and a threaded hole is provided on the upper surface of the front end of the fixing plate, and a bolt pin is installed between the pin hole and the threaded hole.

[0007] In the above technical solution, a stopper is fixedly installed on the rear end of one side of the fixed plate close to the hinged part with a hole, a square socket is opened on the side of the stopper close to the fixed block, and a square block is integrally formed at the rear end of the adapter column, and the square block is plugged into the square socket.

[0008] In the above technical solution, a hinge shaft is installed between the two triangular support plates and the triangular counterweight block.

[0009] In the above technical solution, the support block is located on the right side of the hinge shaft.

[0010] Compared with the prior art, the utility model of a lifting cylinder reciprocating test bench has the following beneficial effects:

[0011] The utility model can use the adapter device to rotatably install the lifting cylinder between the base and the triangular counterweight block. When the lifting cylinder reciprocates and extends, the triangular counterweight block can be driven to flip between the two triangular support plates, thereby simulating the actual working condition of the lifting cylinder, and can reflect the real matching condition of the cylinder barrel and the piston rod, so that the data obtained from the experiment is closer to the actual usage situation, ensuring the product quality and safety performance of the lifting cylinder, and effectively resolving the problem that the traditional mode of monitoring the lifting cylinder in the prior art cannot simulate the actual counterweight condition, and avoiding the problem that the detection result cannot accurately reflect the real matching condition of the cylinder barrel and the piston rod and thus causes adverse effects on the detection effect.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0020] A lifting cylinder reciprocating test bench comprises a base 1 and a lifting cylinder body 5, both ends of the lifting cylinder body 5 are fixedly installed with a hinged part 51 with a hole, and is characterized in that two triangular support plates 11 are symmetrically fixedly installed on the upper surface of the base 1, a triangular counterweight 2 is rotatably installed between the two triangular support plates 11, a support block 3 is fixedly installed on the right side of the upper surface of the base 1, and the support block 3 is used to support the lower side of the triangular counterweight 2, and an adapter 4 is fixedly installed on the left surface of the triangular counterweight 2 and the left side of the upper surface of the base 1, and the two adapters 4 are respectively rotatably connected with the corresponding hinged parts 51 with holes. The installation of the triangular counterweight 2 can simulate the force applied to the actual operation process of the lifting cylinder body 5 during its extension and retraction process, so that the data obtained from the experiment is closer to the actual use situation;

[0021] It should be noted that the two adapters 4 each include a fixing plate 41, and the two fixing plates 41 are respectively welded and fixed to the upper surface of the base 1 and the left surface of the triangular counterweight 2, and two fixing blocks 42 are fixedly installed on one side of the fixing plate 41 close to the hinged portion 51 with a hole, and a through hole 421 is formed through the outer surface of the fixing block 42, and an adapter column 44 is inserted and installed between the two through holes 421, and the hinged portion 51 with a hole is located between the two corresponding fixing blocks 42, and the hinged portion 51 with a hole is rotatably connected to the adapter column 44, and a pin hole 442 is formed through the front end of the adapter column 44, and a threaded hole 411 is formed on the upper surface of the front end of the fixing plate 41, and a bolt pin 45 is installed between the pin hole 442 and the threaded hole 411;

[0022] When in use, the two hinged parts 51 with holes of the lifting cylinder body 5 are respectively placed between the corresponding two fixed blocks 42, and then, the two adapter columns 44 are respectively inserted through the corresponding through-holes 421 and inserted between the corresponding fixed blocks 42 and the hinged parts 51 with holes. At this time, the adapter column 44 is connected with the hinged part 51 to rotate. Finally, after rotating the adapter column 44 to make the pin hole 442 correspond to the bolt pin 45, the bolt pin 45 is inserted through the pin hole 442 and screwed into the threaded hole 411 to fix the position of the adapter column 44. A reciprocating experiment can be carried out. During the experiment, the lifting cylinder body 5 is driven to perform telescopic movements with the help of external equipment, which drives the triangular counterweight block 2 to flip over, simulating the actual usage scenario. The data of the lifting cylinder body 5 during the simulation process can be detected by external detection equipment (the specific detection equipment and detection means used are the existing technology in this field, and no further explanation is given here). Compared with the existing technology, this test bench can effectively simulate the load-bearing and telescopic conditions of the lifting cylinder body 5. The data obtained from the experiment is more in line with the actual usage situation and the experimental effect is better.

[0023] In addition, to further ensure the stability of the adapter column 44, as Figure 5 As shown, a stopper 43 is fixedly installed at the rear end of one side of the fixed plate 41 close to the hinged portion 51 with a hole, and a square socket 431 is opened on the side of the stopper 43 close to the fixed block 42, and a square block 441 is integrally formed at the rear end of the adapter column 44. After the square block 441 is inserted and installed in the square socket 431, the fixed plate 41 can be used to limit the rear end of the adapter column 44, and the bolt pin 45 can be used to limit the front end of the adapter column 44, so that both ends can be lowered, so that the stability of the rotational connection between the adapter column 44 and the adapter portion 51 with a hole is better.

[0024] Specifically, a hinge shaft 21 is installed between the two triangular support plates 11 and the triangular counterweight block 2, and the rotational connection between the triangular support plates 11 and the triangular counterweight block 2 is achieved by installing the hinge shaft 21.

[0025] Finally, in order to ensure that the triangular counterweight block 2 can be turned over by the lifting cylinder body 5 to complete the experiment, the support block 3 needs to be arranged on the right side of the hinge shaft 21 .
