DETAILED DESCRIPTION
[0018] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.
[0019] like Figures 1 to 3 As shown, a horizontal hydraulic tension testing machine comprises a testing machine body 1, a hydraulic actuator cylinder 2 is horizontally arranged on the testing machine body 1, the cylinder body of the hydraulic actuator cylinder 2 is fixedly connected to the testing machine body 1, a slide seat 3 is arranged on the testing machine body 1, the slide seat 3 has the freedom to move along the telescopic direction of the hydraulic actuator cylinder 2, a blocking block 5 is arranged between the slide seat 3 and the hydraulic actuator cylinder 2, the blocking block 5 is detachably connected to the testing machine body 1, the blocking block 5 is used to block the slide seat 3 from moving close to the hydraulic actuator cylinder 2, the two ends of the lifting belt are respectively connected to the telescopic shaft of the hydraulic actuator cylinder and the slide seat 3, and the slide seat 3 is connected to the telescopic shaft of the hydraulic actuator cylinder. The lifting belt is moved to be tightened so as to adapt to the length of the lifting belt through the clamping part, and then the blocking block 5 is installed at one end of the slide 3 close to the hydraulic actuator cylinder, so that the blocking block 5 limits the movement of the slide 3, and finally the hydraulic actuator cylinder 2 is actuated to perform the tension test, so that the hydraulic actuator cylinder 2 does not need to adapt to the length of the lifting belt, and can meet the tension test of lifting belts of various length types; the requirements for the hydraulic actuator cylinder 2 are reduced, and a longer execution range is not required, and the moving range of the slide 3 is determined according to the length of the tested lifting belt, and the length of the test body 1 can be extended or the length of the test body 1 can be increased.
[0020] Furthermore, if Figure 1 As shown, a screw groove 6 is provided on the test machine body 1, a screw 7 is rotatably provided in the screw groove 6, a screw slider 8 is threadedly sleeved on the screw 7, the screw slider 8 is slidably adapted in the screw groove 6, the slide seat 3 is fixed on the top of the screw slider 8, a motor 13 is installed at the end of the test machine body 1 away from the hydraulic actuator 2, the output shaft of the motor 13 is connected to the screw 7, two groups of blocking blocks 5 are provided, and the two groups of blocking blocks 5 are respectively arranged on both sides of the screw groove 6, the test machine body 1 has a plurality of threaded holes 9 on both sides of the screw groove 6, and the plurality of threaded holes 9 are evenly distributed along the axial direction of the screw 7, a through hole 10 is penetrated through the blocking block 5, a threaded pin 11 passes through the through hole 10 and is threadedly adapted in a threaded hole 9, and the two ends of the lifting belt are respectively hung After the telescopic shaft of the hydraulic actuator cylinder 2 is on the slide 3, start the motor 13. The motor 13 drives the screw 7 to rotate, so that the screw slider 8 moves along the axial direction of the screw 7. The screw slider 8 drives the slide 3 to move away from the hydraulic actuator cylinder 2, so that the lifting belt tends to be in a taut state. Then the motor 13 is stopped to install the blocking block 5. The blocking block 5 is installed on the end of the slide 3 close to the hydraulic actuator cylinder 2. The blocking block 5 is aligned with the threaded hole 9 closest to the slide 3, and then the blocking block 5 is fixedly connected to the test body 1 through the threaded pin 11. Then the motor 13 is reversed to make the slide 3 contact the blocking block 5. Finally, the hydraulic actuator cylinder 2 is actuated to perform a tensile test, so that the load-bearing position is the contact surface between the blocking block 5 and the slide 3, protecting the screw 7 from damage.
[0021] Furthermore, the test body 1 is provided with a positioning groove 12 at the position of the threaded hole 9. When the blocking block 5 is fitted in the positioning groove 12, the through hole 10 and the threaded hole 9 are coaxially arranged. The coaxial positioning of the through hole 10 and the threaded hole 9 can be quickly completed through the positioning groove 12, and the blocking block 5 can be directly placed in the positioning groove 12 closest to the slide seat 3.
[0022] Furthermore, if Figure 2 and Figure 3 As shown, the telescopic shaft of the hydraulic actuator cylinder 2 is provided with a clamping mechanism, and the clamping mechanism includes a fixed seat 14 and a hook 15. The fixed seat 14 is fixed on the telescopic shaft of the hydraulic actuator cylinder 2. The fixed seat 14 is provided with a hook 15 at one end close to the slide 3. The long arm of the hook 15 is connected to the fixed seat 14 through a coarse thread. The coarse thread connection has a strong bearing capacity. The fixed seat 14 includes a vertical plate 16 and a horizontal plate 17. The horizontal plate 17 is fixed on the top of the vertical plate 16 to form a 7 shape. The long arm of the hook 15 is connected to the horizontal plate 17. A notch is formed between the short arm of the hook 15 and the vertical plate 16. The short arm of the hook 15 is in contact with the horizontal plate 17. The slide 3 is provided with a clamping mechanism a at one end close to the hydraulic actuator cylinder 2. The structure is the same as that of the clamping mechanism. Since the tensile test requires the lifting belt to be broken, a large reaction force will be generated during the breaking process. The existing unsealed hook is prone to the broken lifting belt being unhooked. Therefore, a fixing seat 14 cooperating with the hook 15 is added. When installing the lifting belt, loosen the hook 15 so that the short arm of the hook 15 is at the bottom. At this time, the short arm of the hook 15 is located below the vertical plate 16, so that a gap for hanging the lifting belt is formed between the short arm of the hook 15 and the vertical plate 16. After the lifting belt is hung, tighten the hook 15 so that the short arm of the hook 15 contacts the horizontal plate 17, thereby closing the gap of the hook 15, ensuring that the lifting belt is not easily unhooked when it is broken, and having higher safety.
