Description

Technical Field

[0001] The utility model relates to the field of hangers, and more specifically to a fire protection pipeline hanger suitable for pipelines of different models. Background Art

[0002] Pipe hangers are an important equipment, mainly used for supporting, fixing and hanging pipes. Pipe hangers play an important role in various industrial equipment and piping systems. Its appearance solves the problems of supporting, fixing and hanging in the piping system, and improves the stability and safety of the piping system. With the continuous development and growth of industrial equipment piping systems, the application of pipe hangers is becoming more and more extensive. At present, pipe hangers have been widely used in industrial equipment piping systems in chemical, water treatment, hospitals, clean rooms, clean rooms, petroleum, natural gas, steel, cement, mining and other industries.

[0003] When installing a pipe hanger, a gantry is used to fix the pipe on the horizontal steel of the hanger. The existing gantry is generally formed by a bent steel bar. In order to match the gantry formed by the bent steel bar with the corresponding pipe, a gantry is only suitable for one type of pipe. After a gantry is made, if the pipe model changes, the gantry of that size cannot be used. Moreover, if it needs to be reused after disassembly, it is easy to encounter different types of pipes and cannot be reused. Another gantry of the corresponding size needs to be prepared, which easily leads to a waste of resources. Utility Model Content

[0004] The utility model aims to provide a fire protection pipe hanger suitable for pipes of different models, so as to solve the problem that the existing pipe hanger is only used for pipes of a single model.

[0005] To achieve the above purpose, the specific technical solution of a fire protection pipe hanger suitable for different types of pipes of the utility model is as follows:

[0006] A fire protection pipe hanger suitable for pipes of different models comprises a pair of vertical steels connected to a ceiling, the other ends of the pair of vertical steels are connected to horizontal steels for placing pipes, and the upper end faces of the horizontal steels are connected to a fixing device composed of at least two fixing parts connected end to end in a rotating manner, so as to lock and fix pipes of different models.

[0007] Furthermore, a plurality of through holes are longitudinally opened on the lower side of a pair of vertical steels, and through holes matching the size of the through holes are opened on both ends of the horizontal steels.

[0008] Furthermore, the fixing device includes a first fixing member, which is rotatably connected to a second fixing member, and the second fixing member is rotatably connected to a third fixing member; the third fixing member is provided with an external thread, and the free end of the third fixing member passes through the upper end surface of the horizontal steel and is fixed on the other side with a nut; a first connecting part is provided at a position of the horizontal steel close to the vertical steel, and the first connecting part is hinged to the other end of the first fixing member.

[0009] Furthermore, the fixing device includes a second fixing member, one end of which is rotatably connected to the third fixing member; the third fixing member is provided with an external thread, and the free end of the third fixing member passes through the upper end surface of the cross steel and is fixed with a nut on the other side; the other end of the second fixing member is hinged with a second connecting part, and the side surface of the second connecting part extends vertically outward to form a threaded connecting end, which passes through a through hole and is fixed with a nut.

[0010] Furthermore, a second long strip-shaped through hole is provided at a position of the horizontal steel near another vertical steel, and the free end of the third fixing member can pass through the second through hole.

[0011] Furthermore, the top ends of the pair of vertical steels are connected with a fixing portion, and at least two through holes are formed on the fixing portion.

[0012] The utility model provides a fire protection pipe hanger suitable for pipes of different models, which has the following beneficial effects:

[0013] Firstly, by adjusting the connection angles between the fixings connected at the head and tail, each fixing can contact and fix pipes of different models, thereby improving the compatibility of the fixing hanger of the utility model with the pipe model, thereby making it more convenient for the actual use of the staff; on the other hand, it can also be recycled and reused.

[0014] Secondly, after each fixing piece contacts the pipeline, a free end of the last fixing piece passes through the second through hole on the horizontal steel and can be directly fixed with a nut. Because the first fixing piece has been hinged to the connecting part, compared with the existing gantry frame that needs to be fixed with nuts at both ends, the fixing device composed of the fixing pieces of the utility model is more convenient and improves the work efficiency in the application to a certain extent.

[0015] Thirdly, by opening a plurality of through holes 1 on the vertical steel and opening through holes 2 on both sides of the horizontal steel whose sizes match those of the through holes 1, the horizontal steel can be connected to different positions of a pair of vertical steels by bolts, so that the staff can adjust the connection position of the horizontal steel and the vertical steel according to the actual construction scene, and further adjust the height of the pipe placed on the horizontal steel. Therefore, the pipe hanger of the utility model is more convenient in construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a fire protection pipe hanger suitable for pipes of different models of the utility model in conjunction with the accompanying drawings.

[0026] like Figure 1 As shown, a first embodiment of a fire protection pipe hanger suitable for different types of pipes includes a pair of vertical steels 1 connected to a ceiling (not shown in the figure), a horizontal steel 2 is connected between the lower ends of the pair of vertical steels 1, and a U-shaped space is formed between the pair of vertical steels 1 and the horizontal steels 2; wherein the vertical steels 1 and the horizontal steels 2 are made of stainless steel, and the shape can be a block-shaped rectangular parallelepiped or a right angle. The utility model preferably uses a right-angled angle steel. The surface where the right angle side of the horizontal steel 2 is located is the upper end surface, and the surface where the other right angle side is located is parallel to the vertical steel 1. A pipe 8 is placed on the upper end surface of the horizontal steel 2. In order to allow the pipe 8 to be stably placed on the hanger, a fixing device for fixing the pipe 8 is also provided in the U-shaped space.

[0027] The fixing device includes a first fixing member 4, a second fixing member 5 and a third fixing member 6 which are connected in a rotatable manner end to end. A first connecting portion 7 is provided on the upper end surface of the horizontal steel 2 near the vertical steel 1. The first fixing member 4 is hinged to the first connecting portion 7. When fixing the pipe 8, the angles between the first fixing member 4, the second fixing member 5 and the third fixing member 6 are adjusted so that the surfaces of the first fixing member 4, the second fixing member 5 and the third fixing member 6 are in contact with the surface of the pipe 8 respectively. Finally, the third fixing member 6 is fixed by a nut 61 after passing downward through the upper end surface of the horizontal steel 2, so that the pipe 8 is fixed on the hanger. Compared with the gantry frame which requires both free ends to be fixed with nuts, the fixing device of the utility model only needs to fix the free end of the third fixing member 6 with a nut, which simplifies the construction process to a certain extent, thereby improving the work efficiency of the installers.

[0028] If the model of the pipe 8 is changed, the angles between the first fixing member 4, the second fixing member 5 and the third fixing member 6 are adjusted, and then each fixing member is brought into contact with the surface of the pipe 8 (i.e., in a tangent state), and then the third fixing member 6 is fixed, so that the pipe hanger of the utility model can be applied to pipes of different models. It should be noted that the lengths of the first fixing member 4, the second fixing member 5, the third fixing member 6 and the horizontal steel 2 are set to be greater than the diameter of the larger-sized pipe in the field, such as greater than 300mm, so that the fire-fighting pipe with a diameter of less than 300mm can be adjusted and fixed by the fixing device of this solution, but the shape formed by each fixing member and the horizontal steel 2 after fixing is different.

[0029] like Figure 1 , Figure 4 and Figure 5 After the fixing device fixes the pipe 8, the shape formed between the first fixing member 4, the second fixing member 5, the third fixing member 6 and the cross steel 2 can be a rectangle, a trapezoid or other irregular shapes.

[0030] like Figure 2 and Figure 3 As shown, when the fixing device adjusts the connection angles of the first fixing member 4, the second fixing member 5 and the third fixing member 6 according to the model of the pipeline 8, in order to facilitate the angle adjustment of the third fixing member 6 and the second fixing member 5, and to allow the other end of the third fixing member 6 to freely change its position in the long side direction of the horizontal steel 2 after passing through the horizontal steel 2, a second long strip-shaped through hole 21 is provided on the upper end surface of the horizontal steel 2, and the other end of the third fixing member 6 can pass through the second through hole 21 and move back and forth in the long strip hole. It should be noted that the end of the third fixing member 6 that passes through the second through hole 21 on the horizontal steel 2 is provided with an external thread. In order to facilitate pipelines of different models, the remaining length of the third fixing member after passing through the second through hole 21 may be longer, so the length of the external thread setting can exceed half of the length of the third fixing member 6.

[0031] like Figure 2 As shown, the vertical steel 1 is connected to the ceiling through the fixing part 3, which can also be an angle steel. One end of the fixing part 3 is connected to the vertical steel 1, which can be detachably connected by bolts or welded. The other end is driven into the ceiling through the through hole 31 on the fixing part 3 through an expansion screw or other connecting piece with a fixing function, so that the entire pipe hanger is fixed; the number of the through holes 31 on one fixing part 3 is at least 2.

[0032] like Figure 1 As shown, as a further improvement to the pipe hanger of this embodiment, a pair of vertical steels 1 are provided with a plurality of through holes 11 in an array on the lower side surface, and through holes (not shown in the figure) corresponding to the size of the through holes 11 are provided on both sides of the horizontal steel 2. The horizontal steel 2 is connected to the pair of vertical steels 1 by bolts passing through the through holes and through holes 11 in sequence. By longitudinally adjusting the horizontal steel 2 to correspond to different through holes 11 on the vertical steel 1, it is convenient for the staff to flexibly adjust the position of the horizontal steel 2 according to the actual construction on site, and then the placement height of the pipe 8 on the hanger can be adjusted, thereby improving the convenience of the pipe hanger in application.

[0033] When in use, the pipe 8 is fixed by adjusting the connection angles among the first fixing member 4, the second fixing member 5, and the third fixing member 6 which are rotatably connected to each other until each fixing member contacts the outer surface of the pipe 8, and then the free end of the third fixing member 6 is passed downward through the cross steel 2 and fixed at the other end face with a nut 61. If it is used for a larger pipe, the second fixing member 5 can be lifted upward relative to the first fixing member 4, and then the connection angle between the third fixing member 6 and the second fixing member 5 is adjusted so that each fixing member contacts the pipe 8, and finally the third fixing member 6 is fixed. In this state, the shape formed by the first fixing member 4, the second fixing member 5, and the third fixing member 6 may be an irregular polygon (such as Figure 5 As shown). If it is used for a smaller type of pipeline, the second fixing member 5 can be adjusted downward relative to the first fixing member 4 so that the first fixing member 4, the second fixing member 5 and the cross steel 2 are all in contact with the surface of the pipeline 8. At this time, since the smaller angle formed by the first fixing member 4 and the second fixing member 5 is an acute angle, the pipeline 8 can be fixed by the first fixing member 4, the second fixing member 5 and the cross steel 2 being in contact with the pipeline 8 at the same time. Therefore, in this case, the third fixing member 6 does not need to be in contact with the pipeline 8, and only needs to pass through the cross steel 2 vertically downward and then be fixed. In this case, the shape surrounded by each fixing rod and the cross steel 2 may be a trapezoid (such as Figure 4As shown). Through the above method, the pipe hanger of this embodiment can be applied to different types of fire pipes, which improves the convenience of practical application; at the same time, the device can be reused, which reduces resource waste to a certain extent. If it is necessary to adjust the connection height between the horizontal steel 2 and the vertical steel 1, the perforations on the horizontal steel 2 can be adjusted to correspond to different through holes 11 on the vertical steel 1, and then fixed with bolts, so that the pipe 8 can have different fixed heights.

[0034] Figure 6 The second embodiment of the utility model is shown. The difference from the first embodiment is that the first fixing member 4 is not used in this embodiment, but the second fixing member 5 and the third fixing member 6 are retained. In addition, the second fixing member 5 is connected to the vertical steel 1 through the second connecting portion 7'. Therefore, in this embodiment, it is equivalent to using the vertical steel 1 to replace the first fixing member 4 in the first embodiment to contact and fix the pipe 8. It is just that in the first embodiment, the first fixing member 4 can rotate around the first connecting portion 7, while in the second embodiment, the vertical steel 1 and the horizontal steel 2 are preferably connected in a vertical state. One end of the second fixing member 5 is hinged to the second connecting portion 7', and the other end is rotatably connected to the third fixing member 6. Figure 7 As shown, the side of the second connection part 7' extends vertically outward to form a connection end 71 with an external thread and a size that matches the through hole 11, so the second connection part 7' can be detachably connected to the vertical steel 1 through the connection end 71 passing through the through hole 11, that is, the second connection part 7' is fixed to the side wall of the vertical steel 1 through the threaded connection end 71 and the nut, and then when it is necessary to adjust the covering area formed by the fixing device and the horizontal steel 2 according to the model of the pipeline 8, it can be matched by changing the connection position of the second connection part 7' and the vertical steel 1. In addition to the above description, the remaining structures and connection relationships of this embodiment are the same as those of the first embodiment and will not be repeated. Therefore, when using the pipe hanger of this embodiment, the surface of the pipe 8 can be made to contact the edge of one of the vertical steels 1 by adjusting the connection position of the pipe hanger and the ceiling, and then the connection angle between the second fixing member 5 and the vertical steel 1 and the connection angle between the second fixing member 5 and the third fixing member 6 are adjusted, so that the second fixing member 5 and the third fixing member 6 are respectively in contact with the pipe 8, and finally the third fixing member 6 passes through the through hole 21 and is fixed with a nut 61.

[0035] If the pipe 8 is replaced with a larger model, the second fixing member 5 can be lifted upward, and after adjusting the second fixing member 5 to contact the pipe 8, the angle between the third fixing member 6 and the second fixing member 5 can be adjusted until the third fixing member 6 contacts the pipe 8, and then the third fixing member 6 can be fixed; if the pipe model is too large, the connection position of the second connecting part 7' and the vertical steel 1 can also be converted to a through hole 11 in the upper direction relative to the original position. If the pipe 8 is replaced with a smaller model, the second fixing member 5 can be adjusted downward to contact the pipe 8, and then the third fixing member 6 can be adjusted to move in the direction close to the pipe 8, so that the angle formed between the third fixing member 6 and the second fixing member 5 is reduced until the third fixing member 6 contacts the pipe 8, and then the third fixing member 6 is fixed. If the pipe model is too small, the connection position of the second connecting part 7' and the vertical steel 1 can also be converted to a through hole 11 in the lower direction relative to the original position. In the above manner, the pipe hanger of this embodiment can be applied to fire pipes of different models, which improves the convenience of practical application.

[0036] It should also be noted that in all the above embodiments, after the third fixing member 6 passes through the second through hole 21 on the horizontal steel 2, if the third fixing member 6 and the horizontal steel 2 are not in a vertical state (for example, Figure 5 As shown), before fixing the third fixing member 6 with the nut 61, an elastic gasket slightly thinner than the nut 61 can be added to prevent the edge of the nut 61 from rigidly contacting the lower end surface of the horizontal steel 2 and damaging the nut 61. Further, the number of fixings on the fixing device of the above embodiment is 2 and 3 respectively, but is not limited to this number. The fixing device can also be composed of a larger number of fixings, as long as each fixing can contact the pipe 8 and the end fixing can be fixed with a nut or other means, so that the pipe 8 is fixed. The setting method is all right. Furthermore, the second connecting portion 7' ​​in the second embodiment can also be welded to the side wall of the vertical steel 1, but this method cannot adjust the fixed position of the second connecting portion 7' ​​on the vertical steel 1, but it does not affect the use of this connection method in pipes within a certain range of models. At the same time, the connecting end 71 on the second connecting portion 7' ​​in the second implementation can also be set in a direction opposite to the second fixing member 5, but in this case, it is necessary to open a through hole in the other side wall of the angular vertical steel 1 to fix the second connecting portion 7'.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
