Description

Technical Field

[0001] This invention relates to the field of pipeline construction tools, and in particular to a quick-connection auxiliary tool for pipeline splicing. Background Technology

[0002] In engineering operations, municipal pipelines often require the connection of new and old pipelines, the relocation and connection of old pipelines, and the connection between existing and new pipelines. For pipelines to be connected, it is usually necessary to cut or remove certain sections of the target pipeline according to the location of the prefabricated pipeline and the target pipeline to ensure that the connection port of the target pipeline can achieve a better "mouth-to-mouth" connection with the connection port of the prefabricated pipeline.

[0003] However, in on-site operations, the entire process of positioning, marking, cutting, and pre-fixing prefabricated pipes and target pipe sections currently relies mainly on the experience of construction workers. The positioning method is relatively traditional and heavily depends on experienced workers, which can easily lead to significant deviations, resulting in a large gap between the joint of the target pipe section and the joint of the prefabricated pipe after cutting. At the same time, the entire positioning and marking process mainly relies on subjective visual judgment, and the cooperation between workers is not well coordinated, resulting in a relatively chaotic situation. This consumes a lot of time and increases the possibility of errors, leading to vague and inaccurate positioning results. Summary of the Invention

[0004] The purpose of this invention is to provide a quick alignment tool for pipe connections, in order to solve the problem in the prior art where pipe connections are made by relying on human eyes for judgment, which consumes a lot of time, increases the amount of error, and leads to blurry and inaccurate positioning results.

[0005] To achieve the above objectives, the present invention provides a quick-connection auxiliary tool for pipe splicing, comprising an adjustable-length connecting rod and a positioning component connected to the connecting rod. Universal joints are arranged at both ends of the connecting rod, and the positioning component is arranged on each universal joint. The positioning component includes a fixing member connected to the universal joint and a flexible telescopic ruler wound around the fixing member. The flexible telescopic ruler is used to be wound around the target splice pipe, and a positioning structure for positioning a drawing pen to draw cutting lines is arranged on the flexible telescopic ruler.

[0006] Preferably, the fixing component includes a flexible connecting plate and a rotating shaft rotatably mounted on the connecting plate. The rotating shaft is arranged at both ends of the connecting plate, and the flexible telescopic ruler is arranged on each rotating shaft. The flexible telescopic ruler is provided with a connecting buckle for connecting two flexible telescopic rulers.

[0007] Preferably, the flexible telescopic ruler is provided with a positioning groove that extends in length, and the positioning groove forms the positioning structure.

[0008] Preferably, the flexible telescopic ruler is also marked with scale values, which are arranged on both sides of the width direction of the flexible telescopic ruler.

[0009] Preferably, the universal joint includes a support rod connected to the connecting rod and a ball joint seat hinged to the support rod, and the fixing member is fixedly connected to the ball joint seat.

[0010] Preferably, the support rod is hinged to the connecting rod.

[0011] Preferably, the connecting rod is a telescopic rod, and a telescopic joint for adjusting the length of the connecting rod is connected to the connecting rod.

[0012] Preferably, the connecting rod includes two rods, each with an external thread in opposite directions. The expansion joint is a threaded sleeve, with internal threads in opposite directions at both ends. The threaded sleeve is threadedly assembled with the two rods.

[0013] Compared with existing technologies, the quick alignment auxiliary tool for pipe connections according to this invention has the following advantages: Positioning components are arranged at both ends of a connecting rod. During pipe connection, the operator adjusts the length of the connecting rod, uses a universal joint to adjust the direction of the positioning components, wraps a flexible telescopic ruler around the target connection pipe, and then uses a drawing pen to draw a cutting line on the target connection pipe using the positioning structure. Afterwards, the operator can keep the flexible telescopic ruler in place and fabricate a prefabricated pipe based on its length and the positioning structure, ensuring that the dimensions of the interfaces at both ends of the prefabricated pipe are consistent with the cutting line of the target connection pipe. Simultaneously, operators can measure the direction angle of the universal joint to determine the angle of the interfaces at both ends of the prefabricated pipe, ensuring that the direction of the interfaces at both ends of the prefabricated pipe is consistent with the direction of the cut of the target connecting pipe. Then, based on the length of the connecting rod and the angle of the universal joint, the distance between the interfaces at both ends of the prefabricated pipe can be calculated, obtaining all the parameters of the prefabricated pipe to be manufactured, ensuring that the prefabricated pipe can be connected "mouth-to-mouth" with the target connecting pipe; this parameterizes the entire positioning process, ensuring that the prefabricated pipe manufacturing is more standardized and accurate, reducing errors, and also facilitating cooperation among operators, improving the efficiency of positioning and marking.

[0018] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] A preferred embodiment of the quick alignment auxiliary tool for pipe connections according to the present invention, such as... Figures 1 to 3 As shown, the quick-connection auxiliary tool for pipe connection includes a connecting rod 1, a positioning component 2, and a universal joint 3. There are two positioning components 2, which are respectively arranged at both ends of the connecting rod 1. There are two universal joints 3, and each positioning component 2 is connected to the connecting rod 1 through the universal joint 3.

[0020] The positioning component 2 is used to fit onto the target connecting pipe 7 to determine the cutting line of the target connecting pipe 7; the universal joint 3 is used to adjust the angle of the positioning component 2, and the angle between the positioning component 2 and the connecting rod 1 is determined by measuring the angle of the universal joint 3, thereby obtaining the angle between the two positioning components 2, which is the angle between the two target connecting pipes 7; measuring the length of the connecting rod 1 can obtain the distance between the two positioning components 2, and from this distance, the distance between the cutting lines on the two target connecting pipes 7 can be obtained, providing corresponding parameters for the fabrication of the prefabricated pipe 8.

[0021] The connecting rod 1 has an adjustable length, which can be adjusted to accommodate target connecting pipes 7 at different distances, thus having a wide range of applications. In this embodiment, the connecting rod 1 is a telescopic rod, and a telescopic joint for adjusting the length of the connecting rod 1 is connected to the connecting rod 1. The method of adjusting the length of the connecting rod 1 using the telescopic joint is simple to operate and convenient to use.

[0022] The connecting rod 1 comprises two rods 11, coaxially spaced apart, each with external threads in opposite directions. The expansion joint is a threaded sleeve 12, with internal threads in opposite directions at both ends. The internal and external threads are mutually compatible, and the threaded sleeve 12 is threadedly assembled with the two connecting rods 1. When connecting to the target connecting pipe 7, the operator rotates the threaded sleeve 12, causing the two rods 11 to axially extend and retract within the threaded sleeve 12 under the action of the threaded structure, adjusting the length of the connecting rod 1 to suit environments with varying distances to the target connecting pipe 7.

[0023] Universal joint 3 includes a support rod 31 and a ball joint seat 32. The positioning component 2 is fixedly connected to the ball joint seat 32. The direction of the positioning component 2 can be changed through the ball joint seat 32, which is suitable for three-dimensional intersection between two target connecting pipes 7. The angle between the two positioning components 2 can also be determined through universal joint 3. The support rod 31 is hinged to the connecting rod 1. When the support rod 31 rotates, it cooperates with the ball joint seat 32 to increase the rotation angle of the positioning component 2, thus expanding its application range.

[0024] The positioning component 2 includes a fixing member and a flexible telescopic ruler 23. The fixing member is used to fix and connect to the ball joint seat 32 of the universal joint 3. The flexible telescopic ruler 23 is wrapped around the fixing member. The flexible telescopic ruler 23 is suitable for wrapping around the target connecting pipe 7. The cutting line of the target connecting pipe 7 is determined by the flexible telescopic ruler 23, which provides a specific reference for drawing the cutting line and the cut. Then, the length of the flexible telescopic ruler 23 is kept unchanged. The interface of the prefabricated pipe 8 can also be determined by the flexible telescopic ruler 23 as a reference, so that the interface of the prefabricated pipe 8 is consistent with the cut of the target connecting pipe 7, and the mouth-to-mouth connection is realized.

[0025] The fixing components include a connecting plate 21 and a rotating shaft 22. The connecting plate 21 is made of a flexible material. There are two rotating shafts 22, which are respectively rotatably mounted at both ends of the connecting plate 21 along its length. There are two flexible telescopic rulers 23, which are respectively wound around the two rotating shafts 22. When the flexible telescopic rulers 23 of the positioning component 2 need to be wound around the target connecting pipe 7, the flexible telescopic rulers 23 are first pulled out from the rotating shafts 22 and wound around the target connecting pipe 7. Then, the ends of the two flexible telescopic rulers 23 are connected to keep the length unchanged. Since the connecting plate 21 is made of a flexible material, the connecting plate 21 can be bent and wound around the target connecting pipe 7, ensuring that the ring formed by the connecting plate 21 and the two flexible telescopic rulers 23 fits tightly with the target connecting pipe 7.

[0026] The flexible telescopic ruler 23 has a certain width, which ranges from 3 to 10 cm. In this embodiment, the width of the flexible telescopic ruler 23 is 5 cm. This width value of the flexible telescopic ruler 23 is convenient to ensure that the shape of the flexible telescopic ruler 23 is consistent and to avoid the flexible telescopic ruler 23 from being twisted, which would result in inaccurate results. At the same time, it also prevents the flexible telescopic ruler 23 from being too large and inconvenient to operate.

[0027] The flexible telescopic ruler 23 is also equipped with scale values ​​4. The scale values ​​4 are arranged along the length direction of the flexible telescopic ruler 23 and on both sides of the width direction of the flexible telescopic ruler 23. That is, each flexible telescopic ruler 23 has two scale values ​​4. The rotating shaft 22 is used as a scale to determine the stretching length of the two sides of the flexible telescopic ruler 23. Based on whether the lengths of the two sides of the flexible telescopic ruler 23 are consistent, it can be determined whether the flexible telescopic ruler 23 is vertically wound on the target connecting pipe 7. When the target connecting pipe 7 needs to be cut at an angle, the tilting direction of the flexible telescopic ruler 23 can also be determined based on the scale values ​​4 on both sides of the flexible telescopic ruler 23.

[0028] The flexible telescopic ruler 23 is also provided with a connecting buckle 6. The connecting buckles 6 on the flexible telescopic ruler 23 at both ends of the connecting plate 21 are compatible. In this embodiment, the connecting buckle 6 is a Velcro, and the two ends of the flexible telescopic ruler 23 at both ends are connected by Velcro to form a closed loop. In other embodiments, the connecting buckle 6 can also be a hook, a hanging ring, a snap, etc. The specific structure of the connecting buckle 6 is the prior art and will not be described in detail here.

[0029] The flexible telescopic ruler 23 is also equipped with a positioning groove 5, which is located on one side of the flexible telescopic ruler 23 and extends along the length of the flexible telescopic ruler 23. The positioning groove 5 forms a positioning structure on the flexible telescopic ruler 23 for positioning the drawing pen to draw the cutting line. After the flexible telescopic ruler 23 is wrapped around the target connecting pipe 7, the connecting buckles 6 at both ends of the flexible telescopic ruler 23 are fastened, and the flexible telescopic ruler 23 and the connecting plate 21 form a closed loop. The operator can draw the cutting line on the target connecting pipe 7 along the positioning groove 5. Subsequently, the cut of the target connecting pipe 7 can be made according to the cutting line, making the drawing of the cut more systematic and accurate.

[0030] The working process of this invention is as follows: When connecting pipes, the operator initially determines the cutting range of the target connecting pipe 7, rotates the threaded sleeve 12, and the rod 11 extends and retracts under the action of the threaded structure. The length of the connecting rod 1 is adjusted, and then the support rod 31 is rotated to adjust the angle of the ball joint seat 32. The connecting plate 21 of the positioning component 2 is attached to the target connecting pipe 7. The operator pulls the flexible telescopic ruler 23, and the two flexible telescopic rulers 23 are connected by the connecting buckle 6 to form a closed loop. The closed loop is tightly fitted onto the target connecting pipe 7. The operator records the value of the scale 4 on the flexible telescopic ruler 23, the length of the connecting rod 1, the support rod 31, and the angle of the ball joint seat 32 to determine the size of the two ends of the prefabricated pipe 8, the interface spacing, and the interface angle, and draws the cutting line on the target connecting pipe 7. According to the obtained parameters, the operator can cut the target connecting pipe 7 and make the prefabricated pipe 8. The prefabricated pipe 8 is welded to the target connecting pipe 7. After quality inspection, the pipe connection operation is completed.

[0031] In summary, this invention provides a quick-connection auxiliary tool for pipe splicing. Its positioning components are arranged at both ends of a connecting rod. During pipe splicing, the operator adjusts the length of the connecting rod, uses a universal joint to adjust the direction of the positioning components, wraps a flexible telescopic ruler around the target splice pipe, and then uses a drawing pen to draw a cutting line on the target splice pipe using the positioning structure. The operator can then keep the flexible telescopic ruler in place and create a prefabricated pipe based on its length and the positioning structure, ensuring that the dimensions of the interfaces at both ends of the prefabricated pipe are consistent with the cutting line of the target splice pipe. Simultaneously, the operator can measure the direction angle of the universal joint to determine the angle of the interfaces at both ends of the prefabricated pipe, ensuring that the direction of the interfaces at both ends of the prefabricated pipe is consistent with the direction of the cut on the target splice pipe. Then, based on the length of the connecting rod and the angle of the universal joint, the distance between the interfaces at both ends of the prefabricated pipe can be calculated, obtaining all the parameters of the prefabricated pipe to be manufactured, ensuring that the prefabricated pipe can be connected "mouth-to-mouth" with the target splice pipe. This parameterizes the entire positioning process, ensuring more standardized and accurate prefabricated pipe manufacturing, reducing errors, and facilitating operator cooperation, thus improving the efficiency of positioning and marking.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
