Description

Technical Field

[0001] This utility model relates to the field of thermal power plant pipeline technology, and in particular to a coordinated control mechanism for the main pipe of parallel units. Background Technology

[0002] The main pipe of a thermal power plant is the core public pipeline for the centralized transportation and distribution of steam, feedwater, etc. It collects the media generated by multiple sets of power equipment (such as boilers) into the main pipe, and then distributes them to multiple sets of energy-consuming equipment as needed through the branches of the main pipe. At the same time, it supports the communication of media between equipment through the main pipe.

[0003] When transporting and collecting media such as steam and feedwater into the main pipe, it is necessary to arrange the pipelines of multiple boilers in parallel and connect them into the main pipe to collect the steam, feedwater and other media generated by multiple boilers.

[0004] Since there is a certain distance between the boiler and the main pipe, when connecting the extension pipes of multiple boilers into the main pipe, it is necessary to use a coordination control mechanism to limit the placement of multiple extension pipes to facilitate precise docking between the extension pipes and the main pipe. Therefore, there is an urgent need for a parallel unit main pipe coordination control mechanism. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a parallel unit main pipe coordination control mechanism, which aims to improve the problem that multiple parallel extension pipes cannot be accurately connected to the main pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a parallel unit main pipe coordination control mechanism, including a support frame, a plug-in sleeve fixedly installed at the bottom of the support frame, a support sleeve sleeved on the outer surface of the plug-in sleeve, a support plate fixedly installed at the bottom of the support sleeve, an electric push rod installed at the top of the support plate, the top of the output shaft of the electric push rod installed on the top of the inner wall of the plug-in sleeve, an installation rod fixedly installed at the top of the support frame, a sliding groove opened at the top of the installation rod, a first clamping block fixedly installed inside the installation rod, an arc-shaped opening one opened at the top of the first clamping block, a second clamping block provided at the top of the first clamping block, an arc-shaped opening two opened at the bottom of the second clamping block, a conveying pipe installed between the first clamping block and the second clamping block, and an adjustment component provided at the top of the second clamping block.

The electric push rod is fixed on the top of the support plate, and the output shaft of the electric push rod is fixed on the top of the inner wall of the plug sleeve. When the electric push rod is powered on, it can drive the plug sleeve to move up and down inside the support sleeve, and drive the support frame, the mounting rod and the first clamping block to rise and fall together, thereby adjusting the position of the first clamping block.

[0008] Preferably, the electric push rod is disposed inside the support sleeve, and there are three support sleeves, electric push rods and plug-in sleeves, which are arranged in a linear array at the bottom of the support frame.

[0009] Preferably, the first clamping block is fixedly installed on the inner wall of the slide groove, and the second clamping block is slidably installed inside the slide groove.

[0010] Preferably, the adjusting assembly includes a closed plate, the closed plate having an internal threaded connection to a threaded post, the bottom of the threaded post penetrating the closed plate and extending to the top of the second clamping block, and a rotating block being fixedly installed on the top of the threaded post.

[0011] Preferably, a buffer spring is installed on the top of the first clamping block, the top of the buffer spring is installed on the bottom of the second clamping block, and a vertical rod is sleeved inside the buffer spring.

[0014] Preferably, a boiler is installed at one end of the conveying pipe, and a main conveying pipe is installed at the other end of the conveying pipe.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the electric push rod is powered on, it can drive the plug sleeve to move up and down inside the support sleeve, and drive the support frame, the mounting rod and the first clamping block to rise and fall together, so as to adjust the position of the first clamping block, so that the output tube can be accurately connected to the connection port of the delivery mother tube after being placed inside the first clamping block.

[0017] 2. In this utility model, the operator can rotate the rotating block to make the second clamping block move up and down along the sliding groove opened in the mounting rod. The second clamping block uses the arc-shaped opening to hold the top of the conveying pipe, and together with the first clamping block, it can clamp and fix the conveying rod, and limit and fix the opening of the conveying pipe to the conveying mother pipe, so as to achieve the effect of clamping and fixing conveying pipes of different specifications.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1-4An embodiment of this utility model provides a parallel unit main pipe coordination control mechanism, including a support frame 1, a plug sleeve 2 fixedly installed at the bottom of the support frame 1, a support sleeve 201 sleeved on the outer surface of the plug sleeve 2, a support plate 202 fixedly installed at the bottom of the support sleeve 201, an electric push rod 203 installed at the top of the support plate 202, the top of the output shaft of the electric push rod 203 installed at the top of the inner wall of the plug sleeve 2, an installation rod 204 fixedly installed at the top of the support frame 1, a sliding groove 205 opened at the top of the installation rod 204, a first clamping block 206 fixedly installed inside the installation rod 204, an arc-shaped opening 207 opened at the top of the first clamping block 206, a second clamping block 208 provided at the top of the first clamping block 206, an arc-shaped opening 209 opened at the bottom of the second clamping block 208, a conveying pipe 210 installed between the first clamping block 206 and the second clamping block 208, and an adjustment component provided at the top of the second clamping block 208;

[0027] An electric push rod 203 is disposed inside the support sleeve 201. Three support sleeves 201, electric push rods 203, and plug-in sleeves 2 are provided, arranged in a linear array at the bottom of the support frame 1. A first clamping block 206 is fixedly installed on the inner wall of the slide groove 205, and a second clamping block 208 is slidably installed inside the slide groove 205.

[0028] A boiler device 5 is installed at one end of the conveying pipe 210, and a conveying main pipe 51 is installed at the other end of the conveying pipe 210;

[0029] Specifically, the plug sleeve 2 can be slidably fitted inside the support sleeve 201. The support plate 202 closes the bottom of the support sleeve 201 and can be placed on the ground. The electric push rod 203 is fixed on the top of the support plate 202. The output shaft of the electric push rod 203 is fixed to the top of the inner wall of the plug sleeve 2. When the electric push rod 203 is powered on, it can drive the plug sleeve 2 to move up and down inside the support sleeve 201, driving the support frame 1, the mounting rod 204 and the first clamping block 206 to rise and fall together. The top of the first clamping block 206 has an arc-shaped opening 207 that matches the curvature of the outer surface of the conveying pipe 210, so that the conveying pipe 210 can be placed inside the arc-shaped opening 207. The second clamping block 208 can move up and down in the sliding groove 205 inside the mounting rod 204, so that the second clamping block 208 and the arc-shaped opening 209 can clamp the top outer surface of the conveying pipe 210, thereby... The clamping block 206 and the second clamping block 208 can clamp and fix the conveying pipe 210, so that the conveying pipe 210 can be precisely fixed and connected to the connection port opened on the outer surface of the conveying mother pipe 51. When the conveying pipe 210 is clamped and fixed by the first clamping block 206 and the second clamping block 208, but still cannot be precisely connected to the connection port of the conveying mother pipe 51, the electric push rod 203 can be activated to drive the support frame 1, the first clamping block 206 and the second clamping block 208 to move up and down, so that the conveying pipe 210 can be precisely connected to the conveying mother pipe 51. Three electric push rods 203 are installed at the bottom of the support frame 1, which can adjust the support frame 1 up and down as a whole, so that the multiple mounting rods 204, the first clamping block 206 and the second clamping block 208 installed at the top of the support frame 1 can move up and down together, so as to achieve the effect of coordinated control and adjustment of the output pipes of multiple boiler equipment 5 to precisely connect to the conveying mother pipe 51.

[0030] It should be noted that the three electric push rods 203 are managed by a control box, which can synchronously control the start of the three electric push rods 203 to drive the support frame 1 to move up and down. The mounting rod 204 is installed on the top of the support frame 1 by screws. The installation position of the mounting rod 204 is determined by accurately measuring the connection port of the corresponding conveying main pipe 51. By adjusting it up and down, the conveying pipe 210 can be connected to the connection port of the conveying main pipe 51.

[0031] Considering the issue of how the first clamping block 206 and the second clamping block 208 clamp and fix the delivery pipe 210, refer to Figure 2 and Figure 4 The first clamping block 206 is fixedly installed on the inner wall of the slide groove 205, and the second clamping block 208 is slidably installed inside the slide groove 205;

[0032] The adjustment assembly includes a closed plate 3, with a threaded post 31 threadedly connected inside the closed plate 3. The bottom of the threaded post 31 passes through the closed plate 3 and extends to the top of the second clamping block 208. A rotating block 32 is fixedly installed on the top of the threaded post 31.

[0033] Specifically, the closing plate 3 is fixed to the top of the mounting rod 204. A threaded hole is provided inside the closing plate 3. The threaded post 31 can be threaded into the threaded hole inside the closing plate 3 and rotated. The bottom of the threaded post 31 is rotatably connected to the top of the second clamping block 208. By rotating the rotating block 32, the operator can make the second clamping block 208 move up and down along the sliding groove 205 opened in the mounting rod 204. The second clamping block 208 uses the arc-shaped opening 209 to hold the top of the conveying pipe 210. Together with the first clamping block 206, it can clamp and fix the conveying rod, and limit and fix the opening of the conveying pipe 210 to the conveying mother pipe 51, so as to achieve the effect of clamping and fixing the conveying pipe 210 of different specifications.

[0034] Furthermore, considering that the conveying pipe 210 will vibrate when conveying water, if the first clamping block 206 and the second clamping block 208 clamp the conveying pipe 210 too tightly, the vibration force of the conveying pipe 210 cannot be buffered. (Referring to...) Figure 3 and Figure 4 The adjustment assembly includes a closed plate 3, with a threaded post 31 threadedly connected inside the closed plate 3. The bottom of the threaded post 31 passes through the closed plate 3 and extends to the top of the second clamping block 208. A rotating block 32 is fixedly installed on the top of the threaded post 31.

[0035] A buffer spring 4 is installed on the top of the first clamping block 206, and the top of the buffer spring 4 is installed on the bottom of the second clamping block 208. A vertical rod 41 is sleeved inside the buffer spring 4.

[0036] The bottom of the vertical rod 41 is fixedly installed on the top of the first clamping block 206, and the top of the vertical rod 41 passes through the second clamping block 208 and extends to the top of the second clamping block 208;

[0037] There are four buffer springs 4 and four vertical rods 41. The four buffer springs 4 and four vertical rods 41 are arranged in a rectangular array between the first clamping block 206 and the second clamping block 208.

[0038] Specifically, four buffer springs 4 are installed between the first clamping block 206 and the second clamping block 208. A vertical rod 41 is installed between each buffer spring 4, with the top of the vertical rod 41 passing through the second clamping block 208. The second clamping block 208 can move vertically up and down at its top with the help of the vertical rod 41, thus limiting the movement path of the second clamping block 208. When the second clamping block 208 moves up and down inside the slide groove 205, it will generate tension and compression forces on the buffer springs 4, thereby causing the threaded column 31 to rotate. When the second clamping block 208 is clamped onto the outer surface of the conveying pipe 210, a buffer gap is reserved for the second clamping block 208. When the conveying pipe 210 is not conveying the medium, the buffer spring 4 pulls the second clamping block 208 to squeeze the conveying pipe 210 for stable clamping. When the conveying pipe 210 vibrates while conveying the medium, the conveying pipe 210 can transmit the vibration force to the second clamping block 208. The second clamping block 208 is buffered by the buffer spring 4, which can buffer the vibration of the conveying pipe 210 and increase the service life of the conveying pipe 210.

[0039] It should be noted that the buffer spring 4 is normally in a contracted state. When the first clamping block 206 moves upward to clamp the conveying pipe 210, it will pull the buffer spring 4. A certain vertical gap is reserved at the rotatable connection between the threaded post 31 and the second clamping block 208, so that the second clamping block 208 can be pulled up and down slightly by the buffer spring 4 to buffer the vibration generated by the conveying pipe 210.

[0040] Working principle: By starting the output shaft of the electric push rod 203, the support frame 1, the first clamping block 206 and the second clamping block 208 can move up and down together, so that the lowest end of the arc-shaped opening 207 of the first clamping block 206 is aligned with the connection port of the conveying main pipe 51. Then the conveying pipe 210 of the boiler equipment 5 can be placed inside the arc-shaped opening 207 of the first clamping block 206. Rotating the rotating block 32 drives the threaded column 31 to rotate, so that the second clamping block 208 moves down along the slide groove 205 and aligns the arc-shaped opening 209 with the top of the outer surface of the conveying pipe 210. By installing multiple mounting rods 204 at different positions on the top of the support frame 1, the parallel output pipes of multiple boilers can be coordinated to be connected to different connection ports of the conveying main pipe 51, so as to achieve the effect of accurately connecting the conveying pipes 210 of different specifications to the conveying main pipe 51.

[0041] After the first clamping block 206 and the second clamping block 208 fix the conveying pipe 210, a certain gap is reserved at the connection between the second clamping block 208 and the threaded post 31. When the conveying medium in the conveying pipe 210 vibrates, the conveying pipe 210 can transmit the vibration force to the second clamping block 208. The second clamping block 208 moves up and down inside the slide groove 205 with the help of the buffer spring 4 to buffer the vibration, which can reduce the vibration of the conveying pipe 210 and increase the service life of the conveying pipe 210.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
