Description

Technical Field

[0001] The utility model relates to the field of chemical pipeline protection, in particular to a chemical pipeline safety cover. Background Art

[0002] Chemical pipeline safety cover, also known as pipeline protective cover, is a device used to protect the safe operation of chemical pipeline system. It is usually a cover structure wrapped around the outside of the pipeline. Some safety covers are integral, like a sealed sleeve wrapped around the pipeline; others are composed of multiple parts, such as several parts connected by flanges or snaps, which are convenient for installation and disassembly. There may be a support structure inside the safety cover to fix the position of the pipeline to prevent the pipeline from being displaced due to external forces (such as fluid impact, vibration, etc.) during operation. At the same time, it can also enhance the overall strength of the safety cover.

[0003] China's public patent application number: CN202420940847.7 provides a safety cover for chemical pipelines. After the left cover body and the right cover body are fixed by bolts and nuts, the elastic force of the spring is used to drive the fitting plate to resist the bolts and nuts, so that the bolts and nuts are protected by the protective plate, and the end of the bolt located in the right assembly port is located in the groove, which is conducive to restricting the bolts and nuts and avoiding the loosening of the bolts, thereby helping to extend the service life of the safety cover. However, during use, if the chemical pipeline needs to be fine-tuned, the safety cover on the outside of the chemical pipeline needs to be removed. After adjusting the pipeline, the safety cover needs to be installed again. The steps are cumbersome and inconvenient to use.

[0004] To this end, we propose a chemical pipeline safety cover. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a chemical pipeline safety cover to solve the above-mentioned problems.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A chemical pipeline safety cover comprises a chemical pipeline body, a safety cover is provided on the outside of the chemical pipeline body, a clamping assembly is provided in the middle of the chemical pipeline body, a pair of symmetrical support assemblies are provided at the bottom end of the chemical pipeline body and inside the safety cover, the support assemblies are adapted to the clamping assembly, and the support assemblies include a pair of brackets fixedly mounted on the inner wall of the safety cover, the top ends of the brackets are fixedly connected to pressure pillows, the top ends of the pressure pillows are provided with slots, the inside of the slots are rotatably connected to rollers, and the top ends of the rollers are in contact with the bottom end of the chemical pipeline body;

[0008] A safety cover is set on the outside of the chemical pipeline body to play an overall protective role, a clamping component is set in the middle of the chemical pipeline body to clamp and limit the pipeline, and a support component is set at the bottom and adapted to the clamping component to jointly ensure the stable placement and flexible adjustment of the pipeline in the safety cover. Specifically, in terms of the support component, a pair of brackets fixedly installed on the inner wall of the safety cover are used to provide a support foundation. The pressure pillow at the top of the bracket serves as a load-bearing structure. The roller rotatably connected in the slot at the top of the pressure pillow fits into the bottom end of the chemical pipeline body.

[0010] By fixing a machine box at the bottom of the safety cover as the basic structure for accommodating and installing other components, a worm is rotated inside the machine box, and one end of the worm passes through the outer wall of the machine box to connect to the handwheel. The worm can then be driven to rotate by turning the handwheel, which serves as a power input component to provide a power source for the movement adjustment of the entire clamping assembly, thereby realizing the clamping control of the chemical pipeline body.

[0011] Furthermore, the clamping assembly further comprises a positioning ring provided in the middle of the chemical pipeline body, the positioning ring being rotatably connected to the inner wall of the safety cover;

[0012] By setting the positioning ring in the middle of the chemical pipeline body and making it rotatably connected to the inner wall of the safety cover, the positioning ring plays a relatively stable intermediate connection and positioning role, providing a basis for the subsequent connection of other components and the realization of movement adjustment around the pipeline, so that the various components connected to it can be reasonably arranged around the chemical pipeline body and work together, assisting in realizing functions such as clamping the pipeline.

[0013] Furthermore, the front end of the positioning ring is rotatably connected to a connecting ring, the front end of the connecting ring is fixedly connected to an auxiliary ring, and the front end of the auxiliary ring is fixedly connected to a plurality of equidistant connecting columns.

[0014] Furthermore, the front end of the connecting column is fixedly connected to a transmission ring, the front end of the transmission ring is fixedly connected to a worm wheel, and the worm wheel is engaged with the worm.

[0015] Furthermore, the rear end of the transmission ring and the front end of the auxiliary ring are rotatably connected with a plurality of equidistant sliding sleeves, the interior of the sliding sleeves is slidably connected with an anti-slip clamping rod, one end of the anti-slip clamping rod is fixedly connected with a rotating shaft, and the end of the rotating shaft away from the anti-slip clamping rod is rotatably connected to the positioning ring.

[0016] Furthermore, an arc-shaped groove adapted to the chemical pipeline body is formed at one end of the anti-slip clamping rod away from the rotating shaft.

[0017] Furthermore, the safety cover is communicated with the machine box.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The chemical pipeline body is supported by the support assembly. At the same time, when the chemical pipeline body is moved, the rollers of the support assembly roll, so that the chemical pipeline body can be moved smoothly;

[0020] 2. Use the clamping assembly to clamp and limit the chemical pipeline body, and adjust the opening and closing degree of the anti-slip clamping rod so that the anti-slip clamping rod can clamp or release the chemical pipeline body. When clamping is required, multiple anti-slip clamping rods are retracted to clamp the chemical pipeline body. When multiple anti-slip clamping rods are opened, the chemical pipeline body can be released. At this time, the chemical pipeline body can be easily moved through the support assembly.

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0031] Reference Figure 1-Figure 7 As shown, a chemical pipeline safety cover in a preferred embodiment of the present utility model includes a chemical pipeline main body 1, a safety cover 2 is provided on the outside of the chemical pipeline main body 1, a clamping assembly 3 is provided in the middle of the chemical pipeline main body 1, and a pair of symmetrical support assemblies 4 are provided at the bottom end of the chemical pipeline main body 1 and inside the safety cover 2. The support assembly 4 is adapted to the clamping assembly 3, and the support assembly 4 includes a pair of brackets 401 fixedly mounted on the inner wall of the safety cover 2, and the top of the bracket 401 is fixedly connected to a pressure pillow 402, and the top of the pressure pillow 402 is provided with a slot 403, and the inside of the slot 403 is rotatably connected to a roller 404, and the top of the roller 404 is in contact with the bottom end of the chemical pipeline main body 1;

[0032] By setting a safety cover 2 on the outside of the chemical pipeline main body 1, an overall protective effect is achieved. A clamping component 3 is set in the middle of the chemical pipeline main body 1 to clamp and limit the pipeline. A support component 4 is set at the bottom and adapted to the clamping component 3 to jointly ensure the stable placement and flexible adjustment of the pipeline in the safety cover. Specifically, with respect to the support component 4, a pair of brackets 401 fixedly mounted on the inner wall of the safety cover 2 are used to provide a support basis. The pressure pillow 402 at the top of the bracket 401 serves as a bearing structure. The roller 404 rotatably connected in the slot 403 at the top of the pressure pillow 402 fits with the bottom end of the chemical pipeline main body 1. When the pipeline moves, the roller 404 can roll, thereby allowing the chemical pipeline main body 1 to move smoothly.

[0033] The clamping assembly 3 includes a box 301 fixedly mounted on the bottom end of the safety cover 2. A worm 302 is rotatably connected to the interior of the box 301. One end of the worm 302 passes through the outer wall of the box 301 and is fixedly connected to a handwheel 303.

[0034] By fixing the machine box 301 at the bottom end of the safety cover 2 as the basic structure for accommodating and installing other components, the worm 302 is rotated inside the machine box 301, and one end of the worm 302 passes through the outer wall of the machine box 301 to connect to the handwheel 303. Subsequently, the worm 302 can be driven to rotate by rotating the handwheel 303, which serves as a power input component to provide a power source for the action adjustment of the entire clamping assembly 3, thereby realizing the clamping control of the chemical pipeline body 1.

[0035] The clamping assembly 3 further includes a positioning ring 304 disposed in the middle of the chemical pipeline body 1, and the positioning ring 304 is rotatably connected to the inner wall of the safety cover 2;

[0036] By setting the positioning ring 304 in the middle of the chemical pipeline body 1 and making it rotatably connected to the inner wall of the safety cover 2, the positioning ring 304 plays a relatively stable intermediate connection and positioning role, providing a basis for the subsequent connection of other components and the realization of movement adjustment around the pipeline, so that the various components connected to it can be reasonably arranged around the chemical pipeline body 1 and work together, helping to realize functions such as clamping the pipeline.

[0037] The front end of the positioning ring 304 is rotatably connected to a connecting ring 305 , the front end of the connecting ring 305 is fixedly connected to an auxiliary ring 306 , and the front end of the auxiliary ring 306 is fixedly connected to a plurality of equidistant connecting posts 307 ;

[0038] The connecting ring 305 rotatably connected at the front end of the positioning ring 304 realizes flexible connection and force transmission between components. The auxiliary ring 306 fixedly connected at the front end of the connecting ring 305 further expands the connection structure. The multiple equidistant connecting columns 307 fixedly connected at the front end of the auxiliary ring 306 play the role of extending the connection and transmitting power, and gradually transmit the power and connection relationship to subsequent components, ensuring that the various parts of the entire clamping assembly 3 can work together to affect the clamping state of the chemical pipeline body 1.

[0039] The front end of the connecting column 307 is fixedly connected to a transmission ring 308 , and the front end of the transmission ring 308 is fixedly connected to a worm gear 312 , which is engaged with the worm 302 ;

[0040] The transmission ring 308 fixedly connected to the front end of the connecting column 307 serves as an important link in the transmission. The worm gear 312 fixedly connected to the front end of the transmission ring 308 is engaged with the worm 302. In this way, when the worm 302 rotates under the drive of the handwheel 303, the transmission characteristics of the worm gear can be used to change the direction of force transmission and achieve a certain deceleration and torque increase effect, driving the transmission ring 308 to rotate accordingly, thereby providing a power basis for the subsequent control of the movement of components such as the anti-slip clamping rod 310, thereby realizing the adjustment of whether the chemical pipeline body 1 is clamped or not.

[0041] A plurality of equally spaced sliding sleeves 309 are rotatably connected to the rear end of the transmission ring 308 and located at the front end of the auxiliary ring 306. An anti-slip clamping rod 310 is slidably connected to the interior of the sliding sleeve 309. One end of the anti-slip clamping rod 310 is fixedly connected to a rotating shaft 311. The end of the rotating shaft 311 away from the anti-slip clamping rod 310 is rotatably connected to the positioning ring 304.

[0042] A plurality of equidistant sleeves 309 rotatably connected through the rear end of the transmission ring 308 and located at the front end of the auxiliary ring 306 provide a sliding guide and limiting structure for the anti-slip clamping rod 310. The rotating shaft 311 fixedly connected at one end of the anti-slip clamping rod 310 is rotatably connected to the positioning ring 304, so that the anti-slip clamping rod 310 can swing with the rotating shaft 311 as the fulcrum. When the transmission ring 308 rotates, the anti-slip clamping rod 310 in the sleeve 309 is driven to slide along the sleeve 309 and swing around the rotating shaft 311, realizing the opening and closing action of the plurality of anti-slip clamping rods 310, thereby clamping or releasing the chemical pipeline body 1.

[0043] The end of the anti-slip clamping rod 310 away from the rotating shaft 311 is provided with an arc groove adapted to fit the chemical pipeline body 1;

[0044] By opening an arc-shaped groove adapted to the chemical pipeline body 1 at one end of the anti-slip clamping rod 310 away from the rotating shaft 311, the anti-slip clamping rod 310 can better fit the pipeline surface when it is retracted to clamp the chemical pipeline body 1, thereby increasing the contact area and friction force, thereby more firmly clamping the chemical pipeline body 1 and ensuring the stable placement of the pipeline in the safety cover.

[0045] The safety cover 2 is connected to the machine box 301;

[0046] By connecting the safety cover 2 with the machine box 301, firstly, the installation and debugging of internal components can be facilitated. For example, the worm 302 and other components in the machine box 301 can be operated and inspected more conveniently. Secondly, if some conditions occur during subsequent use, such as component wear and the need to add lubricant, corresponding maintenance operations can be performed from the connection point without disassembling too much structure, thereby ensuring the normal operation of the entire chemical pipeline safety cover device.

[0047] Specific implementation process: First, when installing the chemical pipeline safety cover, the safety cover 2 is sleeved on the outside of the chemical pipeline main body 1, so that the chemical pipeline main body 1 is located in a suitable position inside the safety cover 2. At this time, the pressure pillow 402 on the bracket 401 of the support component 4 and the roller 404 in the slot 403 thereof are tightly fitted with the bottom end of the chemical pipeline main body 1, providing preliminary support for the pipeline. Then, to clamp and fix the chemical pipeline main body 1, turn the handwheel 303 of the clamping component 3, and the handwheel 303 drives the worm 302 to rotate in the machine box 301. Since the worm 302 is engaged with the worm gear 312 on the transmission ring 308 at the front end of the connecting column 307, the rotation of the worm 302 prompts the worm gear 312 to drive the transmission ring 308 to rotate, and then, the sliding sleeve 309 at the rear end of the transmission ring 308 moves with the rotation of the transmission ring 308, and the anti-slip clamping rod 310 inside the sliding sleeve 309 uses the rotating shaft 311 at one end as the fulcrum, and The anti-skid clamping rod 310 is swung under the action of the limit, and the multiple anti-skid clamping rods 310 are gradually retracted. The end thereof away from the rotating shaft 311 and with the arc groove fits tightly against the chemical pipeline main body 1, and the arc groove is used to increase the contact area and friction with the pipeline, thereby achieving a firm clamping of the chemical pipeline main body 1. When it is necessary to fine-tune the movement of the chemical pipeline main body 1, the hand wheel 303 is rotated in the opposite direction to open the anti-skid clamping rod 310 and release the chemical pipeline main body 1. At this time, under the action of the support component 4, the roller 404 at the bottom end of the chemical pipeline main body 1 can roll in the slot 403, effectively reducing the friction when the pipeline moves, so that the chemical pipeline main body 1 can be smoothly fine-tuned and moved in the safety cover 2. During the entire use process, the connecting structure between the safety cover 2 and the machine box 301 facilitates the installation and commissioning of internal components and subsequent maintenance operations, such as inspection after component wear, addition of lubricant, etc., to ensure the long-term stable operation of the chemical pipeline safety cover device.
