Description

Technical Field

[0001] This utility model relates to the field of mechanical tee testing technology, specifically a mechanical tee torque testing device. Background Technology

[0002] Mechanical tees, as core components for branch connections in pipeline systems, are widely used in critical fields such as fire protection, water supply and drainage, and chemical industry. The torque bearing capacity of their connection parts directly determines the sealing performance and structural safety of the pipeline system, thus requiring a mechanical tee torque testing device.

[0003] Existing mechanical tee torque testing devices suffer from several drawbacks during operation. When the clamping surface of the fixture contacts the outer wall of the branch pipe of the mechanical tee, the inertia of the cylinder thrust causes a momentary impact between the fixture and the sample, which can easily lead to wear on the clamping surface. Replacing the traditional fixture requires tools such as wrenches and screwdrivers, and the disassembly / installation process is time-consuming, resulting in long downtime and affecting testing efficiency. Therefore, there is an urgent need for a mechanical tee torque testing device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a mechanical tee torque testing device to solve the problems of existing mechanical tee torque testing devices. When the clamping surface of the fixture contacts the outer wall of the branch pipe of the mechanical tee, the inertia of the cylinder thrust causes an instantaneous impact between the fixture and the sample, which easily leads to wear of the clamping surface. The traditional fixture replacement requires the use of tools such as wrenches and screwdrivers, and the disassembly / installation takes a long time, resulting in long downtime and affecting the testing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical three-way torque testing device, comprising a workbench, a transmission structure fixedly connected to the top of the workbench, a sensor installed on the outer wall of the transmission structure, a support frame fixedly connected to the top of the workbench, a cylinder fixedly connected to the side wall of the support frame, a buffer chamber fixedly connected to the piston rod of the cylinder, a sleeve column provided on the side wall of the buffer chamber, a slide rod installed on the inner wall of the sleeve column, a buffer spring installed on the outer wall of the slide rod, a guide plate provided on the inner wall of the buffer chamber, a mounting frame fixedly connected to one end of the slide rod, and sliders provided on both sides of the mounting frame.

[0006] The mounting bracket has a slot on its side wall, a clamp is installed on the inner wall of the mounting bracket, an insertion block is provided on the outer wall of the clamp, a return spring is fixedly connected to the inner wall of the insertion block, a buckle is fixedly connected to one end of the return spring, and a magnetic block is provided on the side wall of the insertion block and the inner wall of the mounting bracket.

[0007] Preferably, the buffer spring is sleeved with the slide rod, and the slide rod is sleeved with the sleeve post.

[0008] Preferably, the mounting bracket forms a sliding structure with the slider and the buffer chamber, and the mounting bracket forms a telescopic structure with the buffer spring and the buffer chamber.

[0009] Preferably, the sidewall of the slider is slotted, and the slider is engaged with the guide plate.

[0010] Preferably, the buckle forms a telescopic structure with the insert block via a reset spring, and the buckle is inserted into the slot.

[0011] Preferably, the clamp is inserted into the mounting bracket via a plug, and the plug is fixed to the mounting bracket via a magnetic block.

[0012] Preferably, the buckles are symmetrically arranged around the central axis of the insert block, and the insert block is engaged with the mounting bracket via the buckles.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of a cylinder, buffer chamber, sleeve column, slide rod, buffer spring, guide plate, mounting frame, and slider, addresses the issue of impact damage during the clamping process of traditional devices. Traditional devices suffer from this problem because the cylinder's thrust has inertia, causing a momentary impact between the clamp and the sample, which can easily lead to wear on the clamping surface. In contrast, this utility model only requires activating the cylinder to push the buffer chamber, transferring the impact force to the mounting frame. The mounting frame slides inward, simultaneously compressing the buffer spring. The buffer spring absorbs the impact energy through its deformation or damping action, transforming the momentary impact force into a gentler force, thus preventing damage to the clamp and the mechanical tee. This solves the problem of impact damage during the clamping process of the mechanical tee in traditional devices. 2. This utility model, through its mounting bracket, slider, slot, clamp, insert, return spring, buckle, and magnetic block, addresses the issue that traditional clamp replacement requires tools such as wrenches and screwdrivers, resulting in lengthy disassembly / installation times and prolonged downtime, thus affecting testing efficiency. This utility model, however, utilizes only the buckle and magnetic block to quickly complete installation and replacement without the need for tools, thereby improving clamp replacement time and solving the pain point of long downtime and reduced testing efficiency caused by traditional clamp replacement. This enhances both testing efficiency and convenience. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The embodiments of this utility model will be described below based on its overall structure.

[0018] Please see Figures 1-4 A mechanical three-way torque testing device includes a workbench 1, a transmission structure 2 fixedly connected to the top of the workbench 1, a sensor 3 mounted on the outer wall of the transmission structure 2, a support frame 4 fixedly connected to the top of the workbench 1, a cylinder 5 fixedly connected to the side wall of the support frame 4, a buffer chamber 6 fixedly connected to the piston rod of the cylinder 5, a sleeve column 7 provided on the side wall of the buffer chamber 6, a slide rod 8 mounted on the inner wall of the sleeve column 7, a buffer spring 9 mounted on the outer wall of the slide rod 8, a guide plate 10 provided on the inner wall of the buffer chamber 6, a mounting frame 11 fixedly connected to one end of the slide rod 8, sliders 12 provided on both sides of the mounting frame 11, the buffer spring 9 sleeved with the slide rod 8, and the slide rod 8 sleeved with the sleeve column 7, the mounting frame 11 and the buffer chamber 6 forming a sliding structure through the sliders 12, and the mounting frame 11 through... The buffer spring 9 and the buffer chamber 6 form a telescopic structure. The side wall of the slider 12 is slotted, and the slider 12 is engaged with the guide plate 10. When using the device, the buffer chamber 6 is pushed by the start cylinder 5. When the clamping surface of the clamp 14 contacts the outer wall of the branch pipe of the mechanical tee, due to the inertia of the thrust of the cylinder 5, an instantaneous impact will occur between the clamp 14 and the sample. The impact force is transmitted to the mounting frame 11. The mounting frame 11 is subjected to force and slides inward along the guide plate 10 using the slider 12. Under the action of the impact force, the slide rod 8 slides inward along the blind hole of the sleeve 7, which simultaneously drives the buffer spring 9 to compress. The buffer spring 9 absorbs the impact energy through its own deformation or damping effect, and converts the instantaneous impact force into a smooth force, so as to avoid damage to the clamp 14 and the mechanical tee.

[0019] Please see Figures 1-4A mechanical three-way torque testing device includes a mounting frame 11 with a slot 13 on its side wall, a clamp 14 mounted on the inner wall of the mounting frame 11, an insert block 15 on the outer wall of the clamp 14, a return spring 16 fixedly connected to the inner wall of the insert block 15, and a buckle 17 fixedly connected to one end of the return spring 16. Magnets 18 are provided on the side wall of the insert block 15 and the inner wall of the mounting frame 11. The buckle 17 forms a telescopic structure with the insert block 15 via the return spring 16, and the buckle 17 is inserted into the slot 13. The clamp 14 is inserted into the mounting frame 11 via the insert block 15, and the insert block 15 is fixed to the mounting frame 11 via the magnet 18. The buckles 17 are symmetrically arranged about the central axis of the insert block 15. Block 15 is engaged with mounting bracket 11 via buckle 17. When using the device, by pressing buckle 17 inward, buckle 17 moves under pressure and compresses return spring 16 until buckle 17 disengages from slot 13. Then, pull clamp 14 outward to disengage the magnetic block 18 on the side wall of the insertion block 15 from the magnetic block 18 inside mounting bracket 11. The guide protrusion on the side wall of the insertion block 15 slides along the guide groove of mounting bracket 11. Then, the insertion block 15 is removed from mounting bracket 11. Subsequently, buckle 17 is reset by the rebound of return spring 16. Then, clamp 14 can be removed. The installation of clamp 14 can be completed by reversing the operation. No tools are needed, which improves the replacement time of clamp 14.

[0020] Working principle: In use, first move the device to the appropriate position, then press the buckle 17 inward. The buckle 17 is pressed and drives the return spring 16 to compress until the buckle 17 disengages from the slot 13. Then pull the clamp 14 outward to disengage the magnetic block 18 on the side wall of the insert 15 from the magnetic block 18 inside the mounting bracket 11. Then remove the insert 15 from the mounting bracket 11. Subsequently, the buckle 17 is reset by the return spring 16, allowing the clamp 14 to be removed. Then reverse the operation to complete the installation of the appropriate clamp 14. Then start the cylinder 5 to drive the buffer chamber 6 to push. When the clamp 14 on the buffer chamber 6 engages with the mechanical three-way... When an impact force is generated during clamping, the impact force is transmitted to the mounting bracket 11. The mounting bracket 11, under the force, slides inward along the guide plate 10 using the slider 12, and drives the slide rod 8 to move into the sleeve column 7. Simultaneously, the buffer spring 9 is compressed. The buffer spring 9 absorbs the impact energy through its own deformation or damping effect, converting the instantaneous impact force into a smooth force, thus avoiding damage to the clamp 14 and the mechanical tee. Then, the transmission structure 2 and sensor 3 are used for testing. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
