Description

Technical Field

[0001] This invention relates to the field of metal pipe processing equipment technology, and in particular to a portable flaring device for the end of a flexible copper pipe used for measuring the temperature of a steam turbine thrust bearing. Background Technology

[0002] The turbine thrust bearing temperature measuring device is a sensor device used to monitor the working temperature of the turbine thrust bearing. It is installed in the measuring hole of the thrust bearing and transmits the temperature signal to the monitoring system through the lead wire to realize real-time monitoring of the thrust bearing temperature. During the installation of the device, in order to avoid damage to the lead wire caused by lubricating oil and friction, which would affect the data transmission, workers usually use a flexible copper tube sleeve to protect the lead wire. In order to allow the lead wire to enter and pass through the flexible copper tube sleeve smoothly, workers usually expand the end of the flexible copper tube sleeve in advance.

[0003] While existing portable flaring devices for flexible copper tubes can conveniently and quickly expand the ends of flexible copper tubes, their flaring forms are usually relatively fixed. If different flaring forms are to be achieved, both the upper and lower molds need to be changed simultaneously, which is very time-consuming and labor-intensive. As a result, the ease of use and versatility of these portable flaring devices for flexible copper tubes are poor.

[0004] Based on the above, this invention proposes a portable flaring device for the end of a flexible copper tube used for measuring the temperature of a steam turbine thrust bearing, which is convenient to use and highly versatile. Summary of the Invention

[0005] To overcome the shortcomings of existing portable flaring devices for flexible copper tubes, which can conveniently and quickly expand the ends of flexible copper tubes, but whose flaring forms are usually fixed, and which require changing both upper and lower molds to achieve different flaring forms, which is time-consuming and labor-intensive, resulting in poor ease of use and versatility, this invention provides a portable flaring device for flexible copper tubes used for measuring temperature points of turbine thrust bearings that is easy to use and highly versatile.

[0006] A portable flaring device for the end of a flexible copper tube used for temperature measuring points of turbine thrust bearings includes a mounting frame, a clamping block frame, a threaded pressure rod, a positioning assembly, a template, a rotating shaft, a worm gear, a rotating rod, and a worm wheel. The mounting frame is slidably connected to a pair of clamping blocks, which contact and engage with each other. The mounting frame is threadedly connected to a threaded pressure rod. The mounting frame is equipped with a positioning assembly. The clamping block frame is rotatably connected to a longitudinally distributed template. The template is fixedly connected to a rotating rod, which is rotatably connected to the clamping block frame. The rotating rod is fixedly connected to a worm wheel. The clamping block frame is rotatably connected to a rotating shaft, which is fixedly connected to a longitudinally distributed worm gear. The worm gear meshes with the worm wheel.

[0007] Furthermore, it is particularly preferred that the card holder has pairs of longitudinally distributed limiting grooves.

[0008] Furthermore, it is particularly preferred that the notches on the left and right sides of the template have different shapes.

[0009] Furthermore, it is particularly preferred that the expansion mechanism is also included, which is disposed on the mounting frame. The expansion mechanism includes a guide frame, a top block, a lead screw, a rotating handle, a stop block, and a movable top frame. Pairs of guide frames are fixedly connected to the mounting frame. The guide frames are slidably connected to circumferentially distributed top blocks. The top blocks are fixedly connected to pairs of stop blocks. The mounting frame is rotatably connected to pairs of lead screws. The lead screws are rotatably connected to the guide frames. The lead screws are fixedly connected to rotating handles. The guide frames are slidably connected to pairs of movable top frames. The movable top frames are threadedly connected to the lead screws. The movable top frames are pressed together with the stop blocks.

[0010] Furthermore, it is particularly preferred that both the abutment and the movable top frame are provided with inclined surfaces.

[0011] Furthermore, it is particularly preferred that the device also includes a limiting mechanism, which is disposed on the rotating rod. The limiting mechanism includes a mounting block, a top ball, and a spring. The mounting block is fixedly connected to the rotating rod and is rotatably connected to the block holder. A pair of top balls are slidably connected to the mounting block. A spring is fixedly connected between the top ball and the mounting block, and the top ball is pressed against the block holder.

[0012] Furthermore, it is particularly preferred that the device also includes a compensation mechanism, which is disposed on the block holder. The compensation mechanism includes a compensation block and a locking screw. The compensation block is engaged between a pair of block holders and is threadedly connected to the locking screw.

[0013] Furthermore, it is particularly preferred that the device also includes a fixing mechanism, which is disposed on the block holder. The fixing mechanism includes a locking plate and a protrusion. The locking plate is rotatably connected to the block holder on one side, and the block holder on the other side is fixedly connected to the protrusion, which engages with the locking plate.

[0014] Beneficial effects: 1. The present invention, through components such as templates and worm gears, can quickly switch the shape of the mold when it is necessary to expand the end of the flexible copper tube into different forms of flaring, thereby avoiding the need for manual replacement of the upper and lower molds at the same time, and improving the ease of use and versatility of this portable flaring device for the end of the flexible copper tube.

[0015] 2. This invention, through components such as the top block and lead screw, can conveniently and quickly expand and shape the end of the flexible copper tube into a square shape according to the user's needs, so as to meet the requirements of pipe connection or other processes, thereby improving the ease of use and versatility of this portable flaring device for the end of the flexible copper tube.

[0016] 3. By installing components such as blocks and top beads, this invention can limit the rotation of components such as templates to a certain extent and make a sound when they are rotated to the appropriate position, thereby prompting the worker that the mold shape has been changed. This avoids the worker having difficulty rotating the templates and other components to the appropriate position by feel, thus improving the practicality of this portable flaring device for the end of flexible copper tubes.

[0017] 4. This invention, through components such as compensation blocks and locking screws, can limit and fix flexible copper tubes of different sizes according to user needs and expand their ends to a suitable size, thereby improving the versatility of this portable flaring device for flexible copper tube ends.

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0032] Example 1

[0033] A portable flaring device for the end of a flexible copper tube used for temperature measuring points on turbine thrust bearings, such as... Figures 1-4 As shown, the assembly includes a mounting frame 1, a locking block frame 11, a threaded pressure rod 12, a locking assembly 13, a template 14, a rotating shaft 15, a worm gear 16, a rotating rod 17, and a worm wheel 18. The mounting frame 1 has locking blocks 11 slidably connected to the lower left and right sides, and the two locking blocks 11 are in contact with each other. The mounting frame 1 has a threaded pressure rod 12 threadedly connected to the middle. The locking assembly 13 is installed on the right side of the mounting frame 1. The top of the locking block frame 11 is rotatably connected to a template 14 that is distributed longitudinally. The bottom of the template 14 is fixedly connected to a rotating rod 17, which is rotatably connected to the locking block frame 11. The lower part of the rotating rod 17 is fixedly connected to a worm wheel 18. The locking block frame 11 has a rotating shaft 15 rotatably connected inside, and the rotating shaft 15 has a worm gear 16 that is distributed longitudinally and is fixedly connected to the outside of the rotating shaft 15. The worm gear 16 meshes with the adjacent worm wheel 18.

[0034] like Figures 1-4 As shown, the shapes of the notches on the left and right sides of template 14 are inconsistent.

[0035] When a worker needs to expand the end of a flexible copper tube into a flared shape, they can first insert the end of the flexible copper tube into the corresponding slot of the lower mold, which consists of two pairs of clamping brackets 11, etc., according to the size of the flexible copper tube. The size of the slot gradually decreases from front to back. Then, the two pairs of clamping brackets 11, etc., along with the flexible copper tube, slide backward and enter the sliding groove at the bottom of the mounting bracket 1. When the clamping brackets 11, etc., move along the sliding groove until the end of the flexible copper tube is aligned with the threaded pressure rod 12, the worker can first fix the position of the clamping brackets 11, etc., using the clamping assembly 13. Then, the threaded pressure rod 12 is turned forward, causing the threaded pressure rod 12 to rotate and move downward, expanding the end of the flexible copper tube into a flared shape with the help of the upper mold installed at its bottom. After the expansion is completed, the threaded pressure rod 12 is first rotated in the opposite direction to reset and the clamping assembly 13 is released from fixing the clamping brackets 11, etc., and then the clamping brackets 11, etc., are... The components can be removed from the mounting bracket 1 and the expanded flexible copper tube can be taken out of the slot. When the worker needs to expand the end of the flexible copper tube into other forms of flare, the rotating shaft 15 on the two clamping brackets 11 can be rotated appropriately. The rotation of the rotating shaft 15 will drive the worm gear 16 to rotate together, and the rotation of the worm gear 16 will drive the worm wheel 18, the rotating rod 17 and the template 14 to rotate. When the template 14 and other components rotate 180° under the action of the worm gear 16, the rotating shaft 15 can be stopped. Since the notch shapes on the left and right sides of the template 14 are not the same, when the two clamping brackets 11 and other components are combined together, a new lower mold can be obtained. Then, the upper mold at the bottom of the threaded pressure rod 12 can be replaced. The end of the flexible copper tube can be expanded into other forms of flare using the new upper and lower molds. In this way, the shape of the mold can be quickly switched when the end of the flexible copper tube needs to be expanded into different forms of flare, thereby avoiding the need for manual replacement of the upper and lower molds at the same time.

[0036] Example 2

[0037] Based on Example 1, such as Figures 5-7 As shown, it also includes an expansion mechanism, which is set on the mounting frame 1. The expansion mechanism includes a guide frame 2, a top block 21, a lead screw 22, a rotating handle 23, a stop block 24, and a movable top frame 25. The two guide frames 2 are respectively fixed to the left and right sides inside the mounting frame 1. The guide frames 2 are slidably connected to the outside of the guide frames 2 with circumferentially distributed top blocks 21. The front and rear sides of the inner side of the top blocks 21 are fixedly connected to the stop blocks 24. The left and right sides inside the mounting frame 1 are rotatably connected to the lead screw 22. The lead screw 22 is rotatably connected to the adjacent guide frame 2. The rotating handle 23 is fixedly connected to the rear side of the lead screw 22. The front and rear sides of the guide frame 2 are slidably connected to the movable top frame 25. The movable top frame 25 is threadedly connected to the adjacent lead screw 22. The movable top frame 25 is pressed and engaged with the adjacent stop block 24.

[0038] like Figure 6 and Figure 7 As shown, both the abutment block 24 and the movable top frame 25 have inclined surfaces on the side that are close to each other.

[0039] When workers need to expand the end of a flexible copper tube into a square shape according to the user's requirements, they can first insert the end of the flexible copper tube into the square groove on the mounting bracket 1 and wrap it around the guide bracket 2 and the top block 21. Then, they can rotate the handle 23 and the screw 22 in the forward direction, thereby driving the movable top bracket 25 to move forward. The movable top bracket 25 will contact and press the abutment block 24 when it moves forward, thereby causing the abutment blocks 24 and the top block 21, which are evenly distributed around the circumference, to expand and press the end of the flexible copper tube in all directions. In this way, the end of the flexible copper tube can be easily and quickly expanded and shaped into a square shape in conjunction with the square groove to meet the requirements of pipe connection or other processes. After the expansion is completed, the handle 23 and the screw 22 can be rotated in the reverse direction to drive the movable top bracket 25 to move backward and reset. The abutment blocks 24 and the top block 21 will no longer press and limit the end of the flexible copper tube. At this time, the workers can then pull the expanded and shaped flexible copper tube out of the square groove.

[0040] like Figure 8 and Figure 9 As shown, it also includes a limiting mechanism. The limiting mechanism is set on the rotating rod 17. The limiting mechanism includes a mounting block 3, a top ball 31 and a spring 32. The mounting block 3 is fixedly connected to the middle of the rotating rod 17. The mounting block 3 is rotatably connected to the block holder 11. The top ball 31 is slidably connected to both the left and right sides inside the mounting block 3. The spring 32 is fixedly connected between the top ball 31 and the mounting block 3. The top ball 31 is pressed and engaged with the block holder 11.

[0041] like Figure 8 As shown, the card holder 11 has longitudinally distributed limiting grooves on both the left and right sides inside.

[0042] When components such as the template 14 and rotating rod 17 rotate under the action of the worm gear 16 and rotating shaft 15, components such as the mounting block 3 and ejector ball 31 also rotate along with the rotating rod 17. The ejector ball 31, upon rotation, first disengages from the limiting groove under the action of the locking block frame 11 and moves into the mounting block 3, thereby compressing the spring 32. When the template 14, mounting block 3, and ejector ball 31 rotate 180° and complete the mold shape change, the ejector ball 31 rotates again to align with the limiting groove inside the locking block frame 11, and is then compressed by the spring 32. Under the action of 2, the top ball 31 moves in the opposite direction to reset and re-engages in the limiting groove. The top ball 31, which is engaged in the limiting groove, will not only hinder the rotation of the template 14 and mounting block 3 under the action of the spring 32, but will also impact the inner wall of the limiting groove and make a sound when engaged in the limiting groove. In this way, the template 14 and other components can be limited to a certain extent and make a sound when they are rotated to the appropriate position, thereby prompting the worker to complete the change of mold shape, so as to avoid the worker having difficulty rotating the template 14 and other components to the appropriate position by feeling.

[0043] like Figure 1 and Figure 10 As shown, it also includes a compensation mechanism, which is set on the block holder 11. The compensation mechanism includes a compensation block 4 and a locking screw 41. The compensation block 4 is locked between the lower parts of the left and right block holders 11, and the locking screw 41 is threaded to the rear side of the compensation block 4.

[0044] When a user wants to expand the end of a flexible copper tube to different sizes, and the size of the flexible copper tube is inconsistent with the size of other slots, the worker can first pass the end of the flexible copper tube through the compensation block 4 of the appropriate size, and fix the flexible copper tube and the compensation block 4 together by tightening the locking screw 41. Then, the compensation block 4 and the flexible copper tube are inserted into slots of other sizes and expanded. In this way, flexible copper tubes of different sizes can be limited and fixed according to the user's needs, and their ends can be expanded to the appropriate size. After the expansion is completed, the locking screw 41 is loosened and the flexible copper tube is pulled out from the compensation block 4.

[0045] like Figure 1 and Figure 11 As shown, it also includes a fixing mechanism, which is set on the block holder 11. The fixing mechanism includes a card plate 5 and a protrusion 51. The card plate 5 is rotatably connected to the front side of the right block holder 11, and the protrusion 51 is fixedly connected to the front side of the left block holder 11. The protrusion 51 is engaged with the card plate 5.

[0046] After aligning the two pairs of card holders 11 and inserting the ends of the flexible copper tubes into the slots, the worker can rotate the right card plate 5 to a horizontal position and engage it with the left protrusion 51. This will fix the two aligned card holders 11 together, thus preventing the card holders 11 from shifting or loosening during installation and affecting subsequent processing. When it is necessary to separate the two pairs of card holders 11, the card plate 5 should be rotated in the opposite direction and separated from the protrusion 51.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
