Description

Technical Field

[0001] The present application relates to the field of devices for testing steel sections, and in particular to a pressure testing machine. Background Art

[0002] After the reproduction of steel sections is completed, samples need to be taken to test the performance of the steel sections, including pressure testing. When performing pressure testing on steel sections, a pressure testing machine is usually used. Common pressure testing machines include a frame, a workbench installed on the frame, and a pressure component. When performing a pressure test, the operator needs to move the steel section sample to the workbench, fix the steel section sample on the workbench, and finally control the pressure component to apply pressure to the steel section sample.

[0003] Since the workbench is high from the ground and the steel sample is heavy, the operator needs to exert a lot of force to move the steel sample to the workbench, which increases the operator's labor intensity. Utility Model Content

[0004] In order to reduce the labor intensity of operators, the present application provides a pressure testing machine.

[0005] This application provides a pressure testing machine adopting the following technical solutions:

[0006] A pressure testing machine includes a frame and a workbench installed on the frame. A table is provided on one side of the frame. The top of the frame is connected to support plates located on both sides of the workbench. A screw that passes through one of the support plates is rotatably connected to the ground. A guide rod fixed to the other support plate is also fixed to the ground. The screw passes through the table and is threadedly engaged with the table. The guide rod passes through the table and is slidably plugged into the table.

[0007] By adopting the above technical solution, when it is necessary to test the steel sample, the operator controls the motor to drive the lead screw to rotate, and the lead screw guide rod cooperates to drive the table to move downward until the lower surface of the table contacts the ground. Then the operator moves the steel sample onto the table, and then controls the motor to make the output shaft of the motor rotate in the opposite direction. At this time, the lead screw and the guide rod cooperate to drive the table to move upward until the upper surface of the table is flush with the upper surface of the workbench. At this time, the operator turns off the motor to keep the table in its current position, and finally pushes the steel sample on the table onto the workbench, reducing the need for the operator to manually move the steel sample to the workbench and reducing the labor intensity of the operator.

[0008] Optionally, a sloped platform is fixedly connected to the side wall of the platform away from the frame, and the upper surface of the sloped platform is inclined downward in a direction away from the frame.

[0009] By adopting the above technical solution, the operator can push the steel sample onto the table through the inclined table, reducing the need for the operator to carry the steel sample.

[0010] Optionally, a plurality of balls are rotatably connected to the platform.

[0011] By adopting the above technical solution, when the operator pushes the steel sample to move along the platform, the ball bearings enable the steel sample to move more smoothly.

[0012] Optionally, an extension platform is provided on the sliding sleeve of the side of the platform body close to the frame body, and the side of the extension platform close to the frame body is in a blocked shape. A hydraulic cylinder is embedded in the side of the platform body close to the frame body, and the telescopic rod of the hydraulic cylinder passes through the side wall of the platform body close to the frame body. The hydraulic cylinder is horizontally arranged, and the telescopic rod of the hydraulic cylinder is connected to the corresponding inner wall of the extension platform.

[0013] By adopting the above technical solution, in the initial state, the extension table is located on the side of the frame close to the table body, and the operator pushes the steel sample onto the table body. When the table body moves to the appropriate position, the hydraulic cylinder is controlled to work, and the hydraulic cylinder pushes the extension table toward the workbench until the extension table contacts the workbench. Then the operator can push the steel sample so that the steel sample passes through the extension table and moves to the workbench.

[0014] Optionally, the extension platform is fixedly connected to an upper side wall away from the frame body with an inclined connecting plate, the lower side of the connecting plate is in contact with the upper surface of the platform body, and the connecting plate is provided with a hole for the ball to pass through.

[0015] By adopting the above technical solution, the connecting plate connects the upper surface of the table body with the upper surface of the extension table, and the operator can smoothly push the steel sample on the table body to the extension table.

[0016] Optionally, a horizontally arranged connecting rod is fixedly connected to the inner wall of the extension platform opposite to the frame body, and the connecting rod is slidably inserted in the platform body.

[0017] By adopting the above technical solution, the connecting rod supports the extension platform, thereby reducing the downward tilt of the extension platform close to the frame.

[0018] Optionally, the ball contacts and rolls with the inner top surface of the extension platform.

[0019] By adopting the above technical solution, the ball bearing cooperates with the extension platform, making the extension platform move more smoothly.

[0020] Optionally, a lower surface of the support plate away from the frame body is fixedly connected to a pillar, and the lower end of the pillar is fixed to the ground.

[0021] By adopting the above technical solution, the pillars support the support plate, thereby reducing the occurrence of the support plate tilting downward on the side away from the frame.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up the table body, support plate, lead screw, guide rod and motor, it reduces the need for operators to manually carry the steel samples to the workbench, thus reducing the labor intensity of operators;

The pillar 13 supports the support plate 12, thereby reducing the occurrence of the support plate 12 tilting downward on the side away from the frame 1.

[0032] A lead screw 2 is provided at one of the support plates 12, and a guide rod 3 is provided at the other support plate 12.

The lower end of the guide rod 3 is fixedly connected to the ground, and the upper end of the guide rod 3 is fixedly connected to the corresponding support plate 12; the upper surface of the support plate 12 corresponding to the lead screw 2 is fixedly connected to the motor 4, and the output shaft of the motor 4 is coaxial with the lead screw 2, and the output shaft of the motor 4 is fixed to the upper end of the lead screw 2.

[0033] A platform 5 is also provided on one side of the frame 1, the lead screw 2 passes through the platform 5 and is threadedly connected to the platform 5, and the guide rod 3 passes through the platform 5 and is slidably plugged into the platform 5; a ramp 51 is fixedly connected to the side wall of the platform 5 away from the frame 1, and the upper surface of the ramp 51 is inclined downward in the direction away from the frame 1, and a plurality of balls 52 are also rotatably connected to the upper surface of the platform 5.

[0034] Reference Figure 1 and Figure 2 , an extension platform 6 is provided on the sliding sleeve of the side of the platform 5 close to the frame 1, and the side of the extension platform 6 close to the frame 1 is in a blocked shape. The inner top surface of the extension platform 6 is in rolling cooperation with the ball 52, and the upper side wall of the extension platform 6 away from the frame 1 is fixedly connected with an inclined connecting plate 61, and the side of the connecting plate 61 away from the extension platform 6 is inclined downward and in contact with the upper surface of the platform 5. A hole for the ball 52 to pass through is also opened on the connecting plate 61; refer to Figure 2 and Figure 3 A hydraulic cylinder 7 is embedded in the platform body 5 and fixed. The telescopic rod of the hydraulic cylinder 7 passes through the side wall of the platform body 5 close to the frame body 1. The hydraulic cylinder 7 is arranged horizontally. The telescopic rod of the hydraulic cylinder 7 is fixed to the inner wall corresponding to the extension platform 6. A horizontally arranged connecting rod 8 is fixedly connected to the inner wall where the extension platform 6 and the hydraulic cylinder 7 are connected. The connecting rod 8 is slidably connected to the platform body 5.

[0035] In the initial state, the telescopic rod of the hydraulic cylinder 7 is retracted, and the extension platform 6 is located on the side of the frame 1 close to the platform 5. The operator controls the motor 4 to work, and the motor 4 drives the screw 2 to rotate. The screw 2 cooperates with the guide rod 3 to drive the platform 5 and the extension platform 6 to move downward until the extension platform 6 contacts the ground; the operator pushes the steel sample to move the steel sample through the inclined platform 51 to the platform 5, and then controls the output shaft of the motor 4 to drive the screw 2 to rotate in the opposite direction, so that the platform 5 and the extension platform drive the steel sample to move upward.
