Description
Technical Field
The invention relates to a tool for installing a pipeline, in particular to an auxiliary device for installing a chemical pipeline.
Background
Chemical pipelines and valves are indispensable components in chemical production and are links of various chemical equipment. The chemical tube is divided into the following types according to the materials: metal tubes and non-metal tubes. The common metal pipes include cast iron pipes, seamed steel pipes, seamless steel pipes, copper pipes, aluminum pipes, and lead pipes. The non-metal pipes mainly include plastic pipes, glass pipes, ceramic pipes and cement pipes. Among them, cast iron pipes and seamless steel pipes are used in large quantities in view of cost. Cast iron pipes and seamless steel pipes have the advantages of high temperature resistance and high strength, but generally have poor corrosion resistance, and cannot be used for transporting corrosive chemical materials. Plastic pipes and rubber pipes are more typical of pipes for non-metals. Among them, the most commonly used plastic pipes at present include rigid polyvinyl chloride pipes, flexible polyvinyl chloride pipes, polyethylene pipes, polypropylene pipes, and metal pipes, and the surfaces of which are sprayed with polyolefin, polychlorotrifluoroethylene, etc. The rubber tube is generally made of natural rubber or synthetic rubber. Among them, the plastic pipe has the advantages of good corrosion resistance, light weight, convenient molding, easy processing, and the disadvantages of low strength and poor heat resistance. The rubber tube has the advantages of good corrosion resistance, light weight, good plasticity, flexible and convenient installation and disassembly, and the rubber tube has the defect that the rubber tube can only be applied to occasions with low pressure requirements. Therefore, the application of plastic pipes still has great advantages and versatility, just as compared to plastic pipes and rubber pipes. However, due to the inherent low strength of the plastic pipe, the installation of the plastic chemical pipeline in the industry is still relatively troublesome at present, and no proper tool is provided for avoiding the pipeline damage or invisible damage in the installation process. Especially, the hidden damage of the leakage which may happen in the later period is likely to cause the safety production hidden trouble.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Various aspects and features of the present invention are described herein with reference to the drawings.
These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment, given as a non-limiting example, with reference to the accompanying drawings.
It should also be understood that, although the invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of the invention, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
The above and other aspects, features and advantages of the present invention will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.
As shown in fig. 2 to fig. 5, an auxiliary device for installing a chemical pipeline according to an embodiment of the present invention includes: the pipeline connecting device comprises a base body 1, wherein a hollow part 4 which is convenient for a pipeline 5 to pass through is formed on the base body 1; the hollow-out 4 itself merely facilitates the continued extension of the pipe 5 towards the lower installation space without actually participating in the clamping. Actually clamping and fixing the pipeline 5 to facilitate the installation work, in the present invention, a clamping mechanism 2 is required to implement, as shown in fig. 4 to 5, the clamping mechanism 2 may specifically include a first actuating portion 21 and a second actuating portion 22 which are located at two sides of the hollow portion 4 and have the same structure, and the first actuating portion 21 and the second actuating portion 22 which have the same structure ensure that operators at two opposite sides can conditionally form uniform clamping force at two opposite sides of the pipeline 5, and form a clamping space 20 right above the hollow portion 4 to clamp the pipeline 5 passing through the hollow portion 4. Further, specifically, the first actuating portion 21 and the second actuating portion 22 may respectively include two opposite bearing seats 31 and a first rotating shaft 33 connected between the two bearing seats 31 through a bearing 32, a clamping member 222 is integrally and rotatably disposed on the first rotating shaft 33, and the clamping member of the first actuating portion 21 and the clamping member of the second actuating portion 22 may move in a first predetermined angle relative to a vertical direction to clamp the pipe. The size of the first predetermined angle depends on the diameter of the pipe 5 adapted by the auxiliary device of the present invention, but the first predetermined angle is not set too large in consideration of the clamping effect, and thus, it is preferably an acute angle and the angle is between 30 ° and 60 °. Also in view of the clamping effect, as shown in fig. 4, in some embodiments, when the clamping member of the first actuating portion 21 and the clamping member of the second actuating portion 22 perform the clamping operation in opposite directions, the structure of the clamping member 222 of the second actuating portion 22 is shown, but the structure of the clamping member and the structure of the clamping member are the same. The side of the pipe 5 that is in contact with the pipe is configured as an arc. In a further preferred embodiment, as shown in the figure, the arc-shaped surface is provided with a slot 2221 along a tangential direction thereof, and the slot 2221 enables the pipe to be at least partially positioned in the slot 2221 during a clamping operation, so as to prevent slipping. In addition, a plurality of ratchet teeth 2222 perpendicular to the clamping grooves 2221 are formed on the arc-shaped surface, so that the anti-skid effect can be further improved.
In addition, in the above application of the present invention, when the clamping operation is performed, the clamping member may be pressed by a tool when the clamping is performed by the constructors on both sides, but considering the actual force factor of human perception, it is more preferable to directly operate the clamping member by hand or foot. For this reason, as shown in fig. 4, the clamping member 222 is preferably configured to have a clamping end (not labeled) with the arc-shaped surface and an extending portion 2223 for facilitating the stepping operation, respectively, with respect to both ends of the first rotating shaft 33. In this way, the worker only needs to apply force to the clamping end or the extending portion 2223 by feet, respectively, to operate the clamping member 222. Meanwhile, as a further improvement, the extending portion 2223 may be further provided with a pedal 221 for stepping. The pedal 221 extends along the length direction of the extending portion 2223, and has one end covering at least a portion of the clamping end and the other end extending out of at least the extending portion. The foot operation of the operator is more convenient. On the basis of this, fig. 6 shows another improvement of this solution, in which the operator is considered to apply a force to the gripping end continuously while the gripping is being performed, and if the duration is long, fatigue or misalignment may occur. Therefore, as shown in fig. 6, the base body 1 may be configured to include a support portion 11 and a mount table 12 configured on the support portion 11, and the foregoing embodiment may also follow this configuration, with the bearing housing 31 provided on the mount table 12. However, in this application, a clamping table 13 can be disposed on the supporting portion 11 between the assembly platforms and directly below the pedal 221, and a return spring 7 is disposed on the clamping table 13, wherein the return spring 7 is used for keeping the pedal 221 in the clamping state. This means that the return spring 7 provides an initial suitable pretension, at which point the constructor only needs to pay a small stepping force to achieve clamping in the clamped state. When the release is needed, the release can be completed only by lightly stepping on the pedal at the position corresponding to the extending portion 2223.
With the above embodiments, there may also be a problem in that, although the clamp member 222 is integrally rotatably provided on the first rotating shaft 33, there is inevitably a risk of relative rotation or a slip-off in which stress concentration occurs with respect to a pipe requiring a large clamping force. Therefore, as a further improvement, as shown in fig. 2 to 6, a second crank 35 is respectively arranged on the first rotating shaft 33 at two sides of the clamping member 222, a second shaft hole 2225 parallel to the first rotating shaft is arranged at the end part close to the clamping end, and the free end of the second crank 35 is connected with a second rotating shaft 37 passing through the second shaft hole 2225. Therefore, the clamping can be realized relatively stably by applying force to the clamping end.
As can also be seen with reference to fig. 2 to 6, in the above application of the present invention, the first and second actuating portions 21 and 22 require two operators to operate simultaneously. This may not only cause waste of manpower, but also may cause problems of inconsistent force application between two persons or asynchronous timing. For this purpose, as shown in the figure, in the present invention, an interlocking mechanism 3 may be further included, and the interlocking mechanism 3 is configured to interlock the first operating portion 21 and the second operating portion 22. In other words, no matter the operator on the first operating portion 21 side or the second operating portion 22 side, the clamping members can be operated to move in the opposite directions to clamp the workpiece. Specifically, the linkage mechanism 3 includes first cranks 34 respectively disposed at two ends of the first rotating shaft 33, the first cranks and the first rotating shaft rotate integrally, and free ends of the first cranks corresponding to the first actuating portion 21 and the first cranks corresponding to the second actuating portion are connected by a connecting rod 36 to form a crank link mechanism. In addition, it should be noted that, in consideration of the transmission characteristics of the crank-link mechanism and the pipe clamping effect, in the present invention, as shown in fig. 2 and 3, an included angle b is formed between the first crank and the second crank corresponding to the first actuating portion 21, an included angle a is formed between the first crank and the second crank corresponding to the second actuating portion 21, the included angle b is between 30 ° and 40 °, and the included angle a is complementary to the included angle b.
It may also be noted that, in the example of figures 1 and 7 of the present invention, an auxiliary support 6 is also disclosed, which auxiliary support 6, in the present invention, does not in fact grip the pipe 5, but merely ensures that it is constrained in a vertical direction so as not to topple over. As shown in fig. 1 and 7, the auxiliary support at least includes a plurality of constraining rings 61 sleeved on the pipeline 5, a plurality of support rods 62 forming an included angle with the pipeline 5 are uniformly distributed on the periphery of the constraining rings 61, and the constraining rings 61 are formed by fastening semicircular ring members, in the illustration, a first ring body 611 and a second ring body 622 are respectively provided, so as to facilitate the detachment and the installation of the constraining rings on the pipeline 5. In addition, in this application, considering the complexity of the construction environment, in fact, the included angle between the supporting rod 62 and the pipeline 5 is preferably dynamically adjustable, for this purpose, in a further modification, the restraining ring 61 is preferably provided with two, and further includes a dynamic supporting mechanism 63, the dynamic supporting mechanism 63 specifically includes a first sub-link 631, a main driving rod 632 and a second sub-link 633, the ends of which are hinged together, and the main driving rod 632 is provided with an electric control cylinder 6321, the output end of the electric control cylinder 6321 applies force to the hinge points of the three, the free end of the first sub-link 631 is hinged with the approximate middle of the supporting rod 62, the free end of the main driving rod 632 is hinged with the restraining ring 61 located at the lower position, the second sub-link 633 is configured as a telescopic rod including a sleeve 6331 hinged with the restraining ring 61 located at the upper position and a telescopic rod 6332 sleeved with the sleeve 6331, the telescopic rod is actually connected to the junction of the three. Through the actuation of the electric control cylinder 6321, the length of the second auxiliary link 633 changes, and the included angle between the support rod 62 and the pipeline 5 changes, so that a more flexible support space is formed.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
