Description

Technical Field

[0001] This utility model relates to the technical field of pipe sample testing equipment, specifically to an MPP pipe sample testing support structure. Background Technology

[0002] MPP pipes are commonly used in power cable protection, municipal engineering, and other fields. Their strength, toughness, and other properties need to be verified through tensile, bending, and compression tests. The supporting structure acts as a "fixed base" during testing.

[0003] Currently, most existing support structures for MPP pipe sample testing may experience instability when clamping and fixing MPP pipes of different sizes. This can easily cause slight shaking or slippage during pipe testing, affecting the effectiveness of the test. In addition, the vibration generated by the support structure during pipe testing can also affect the test results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an MPP pipe sample testing support structure, which has the advantages of stable clamping and high device stability, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: an MPP pipe sample inspection support structure, including a shock-absorbing mechanism, a plurality of first-order limit rods fixedly installed on the upper end face of the shock-absorbing mechanism, a first-order hydraulic rod fixedly installed on the upper end face of the shock-absorbing mechanism, a base fixedly installed on the upper end face of the first-order hydraulic rod, a plurality of second-order limit rods fixedly installed on the lower end face of the base, a support block fixedly installed on the upper end face of the base, a pipe body slidably connected inside the support block, and a clamping mechanism fixedly installed on the upper end face of the support block.

[0006] As a preferred embodiment of this utility model, a plurality of support rods are fixedly installed on the lower end face of the shock absorption mechanism, and anti-slip pads are fixedly installed on the lower end face of each of the plurality of support rods.

[0007] As a preferred technical solution of this utility model, two No. 1 elastic pads are fixedly installed on the inner bottom surface of the support block, and multiple No. 1 wear-resistant strips are fixedly installed on the upper surface of the two No. 1 elastic pads.

[0008] As a preferred embodiment of this utility model, the shock absorption mechanism includes a first support plate, a shock absorption pad is fixedly installed on the lower end face of the first support plate, a plurality of third limit rods are fixedly installed on the inner top surface of the first support plate, a second support plate is slidably connected to the lower end face of the first support plate, and a plurality of shock absorption springs are fixedly installed on the inner bottom surface of the second support plate.

[0009] As a preferred embodiment of this utility model, the clamping mechanism includes a second hydraulic rod, and a clamping block is fixedly installed on the lower end face of the second hydraulic rod.

[0010] As a preferred technical solution of this utility model, two No. 2 elastic pads are fixedly installed on the lower end face of the clamping block, and multiple No. 2 wear-resistant strips are fixedly installed on the lower end face of the two No. 2 elastic pads.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The MPP pipe sample inspection support structure uses a second hydraulic rod in the clamping mechanism to push the clamping block downwards, thereby clamping and fixing the pipe body between the clamping block and the support block. The first and second elastic pads, along with the first and second wear-resistant strips, increase the contact area and friction between the pipe body and the support and clamping blocks, making the pipe body more securely clamped and fixed. This prevents the pipe from shaking or shifting during sample inspection, which would affect the sample inspection results.

[0012] 2. The MPP pipe sample inspection support structure has a shock-absorbing mechanism installed in it. The main body of the pipe is clamped and fixed on the upper end of the shock-absorbing mechanism. When the pipe is sampled, the vibration generated will be absorbed and dispersed by the shock-absorbing springs and shock-absorbing pads inside the shock-absorbing mechanism, thereby preventing the entire support structure from shaking and affecting the sample inspection results of the pipe.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 A support structure for testing MPP pipe samples includes a shock-absorbing mechanism 2. Multiple first-position limit rods 6 are fixedly installed on the upper end face of the shock-absorbing mechanism 2. A first-position hydraulic rod 5 is fixedly installed on the upper end face of the shock-absorbing mechanism 2. A base 7 is fixedly installed on the upper end face of the first-position hydraulic rod 5. Multiple second-position limit rods 12 are fixedly installed on the lower end face of the base 7. A support block 8 is fixedly installed on the upper end face of the base 7. A pipe body 1 is slidably connected inside the support block 8. A clamping mechanism 9 is fixedly installed on the upper end face of the support block 8. In the above structure, the vibration damping mechanism 2 absorbs and disperses the vibration generated by the support structure when testing the pipe sample, thereby preventing the shaking of the support structure from affecting the pipe test results. The height of the support structure can be freely adjusted according to the test sample requirements by the first hydraulic rod 5. The second limiting rod 12 slides inside the first limiting rod 6, thereby limiting the displacement of the base 7. The support block 8, together with the clamping mechanism 9, can clamp and fix the pipe body 1 inside the support structure.

[0017] In a preferred embodiment, a plurality of support rods 3 are fixedly installed on the lower end face of the shock absorption mechanism 2, and anti-slip pads 4 are fixedly installed on the lower end face of each of the plurality of support rods 3. In the above structure, the anti-slip pad 4 installed at the lower end of the support rod 3 can prevent the support structure from shifting when the pipe is inspected, thereby avoiding affecting the test results of the pipe sample.

[0018] In a preferred embodiment, the shock absorption mechanism 2 includes a first support plate 201, a shock absorption pad 203 fixedly installed on the lower end face of the first support plate 201, a plurality of third limit rods 205 fixedly installed on the inner top surface of the first support plate 201, a second support plate 202 slidably connected to the lower end face of the first support plate 201, and a plurality of shock absorption springs 204 fixedly installed on the inner bottom surface of the second support plate 202. In the above structure, the damping mechanism 2 and the pipe clamping part are connected by the first support plate 201. When the pipe is tested, if the support structure vibrates, the vibration force will be absorbed and dispersed by the damping pad 203 and damping spring 204 inside the damping mechanism 2, thereby avoiding the vibration from affecting the structure of the pipe sample test.

[0019] In a preferred embodiment, two No. 1 elastic pads 10 are fixedly installed on the inner bottom surface of the support block 8, and multiple No. 1 wear-resistant strips 11 are fixedly installed on the upper surface of each of the two No. 1 elastic pads 10. The clamping mechanism 9 includes a No. 2 hydraulic rod 901, a clamping block 902 is fixedly installed on the lower surface of the No. 2 hydraulic rod 901, two No. 2 elastic pads 903 are fixedly installed on the lower surface of the clamping block 902, and multiple No. 2 wear-resistant strips 904 are fixedly installed on the lower surface of each of the two No. 2 elastic pads 903. In the above structure, the pipe body 1 is clamped and fixed between the support block 8 and the clamping mechanism 9. The first elastic pad 10 and the second elastic pad 903 can increase the contact area between the pipe body 1 and the support block 8 and the clamping mechanism 9. At the same time, the first wear-resistant strip 11 and the second wear-resistant strip 904 can increase friction, making the pipe body 1 clamped and fixed more firmly. This can effectively prevent the pipe body 1 from shaking and slipping during the sample inspection process, thereby making the pipe sample inspection results more accurate.

[0020] The working principle is as follows: the pipe body 1 is placed between the support block 8 and the clamping mechanism 9. Then, under the push of the second hydraulic rod 901, the clamping block 902 will press down to fix the pipe body 1. The first elastic pad 10 and the second elastic pad 903, together with the first wear-resistant strip 11 and the second wear-resistant strip 904, can increase the friction and the contact area between the pipe body 1 and the support block 8 and the clamping mechanism 9, so that the pipe body 1 can be clamped and fixed more stably. This effectively avoids the pipe body 1 from shaking and shifting during pipe inspection, which would affect the pipe sample inspection results. During the pipe sample inspection process, the vibration generated by the support structure will be absorbed and dispersed by the damping spring 204 and damping pad 203 in the damping mechanism 2, thereby avoiding the shaking of the support structure from affecting the pipe sample inspection results.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
