Description

Technical Field

[0001] The invention relates to the technical field of chemical pipeline equipment installation, and in particular to a combined limiting bracket. Background Art

[0002] With the development of petrochemical equipment, the equipment is large-scale, but the space occupied is small, the equipment layout is compact, and the selection of combined brackets is increasing. Figures 1 to 3 The figure shows a limit bracket used in the installation of pipelines in the prior art, including a support base plate 1', a pipe support base plate 2', a spring assembly 3', a pipe support 7' and a guide limiter 4'. The spring assembly 3' includes 4 groups of springs arranged in a 2*2 matrix. The spring assembly 3' is fixed on the support base plate 1'. The upper end of the spring assembly 3' is movably connected to the pipe support base plate 2'. The upper surface of the pipe support base plate 2' is welded with a pipe support 7', and the pipe support 7' is used to support the pipeline 6'. The lower end of the guide limiter 4' is fixed on the support base plate 1', and the upper end of the guide limiter 4' is surrounded by the pipe support base plate 2' and interacts with the side of the pipe support base plate 2'. Since the guide limiter 4' is arranged around the tube support bottom plate 2', the area of ​​the support bottom plate 1' is at least larger than the sum of the areas occupied by the tube support bottom plate 2' and the guide limiter 4', more space is required when installing the limiter bracket, and the guide limiter 4' generally surrounds the spring assembly 3', making it difficult to remove the positioning block in the spring assembly 3', and the displacement scale of the spring assembly 3' cannot be seen. In addition, the existing limiter bracket such as Figures 1 to 3 As shown, an installation space with a square bottom is required. However, when the installation space on site is small, the width in one direction is shorter than the predetermined square side length, while the width in another direction is longer than the predetermined square side length. In this case, the existing limit bracket cannot be installed. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a combined limiting bracket in view of the current status of the prior art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: the combined limit bracket is used to support the pipeline, and is characterized by: comprising:

[0005] Support base plate;

[0006] A spring assembly is arranged on the supporting bottom plate;

[0007] A pipe support bottom plate, which is a rectangular plate and is disposed on the spring assembly. The pipe support bottom plate can move horizontally relative to the spring assembly. Inwardly recessed notches are disposed at the four top corners of the pipe support bottom plate, or inwardly recessed notches are disposed on two opposite sides of the pipe support bottom plate; and

[0008] The number of the guide limiters is the same as the number of the notches, the bottom ends of the guide limiters are fixed on the support bottom plate, and the top ends of the guide limiters are respectively limitedly set in the notches.

[0009] Furthermore, the notch is rectangular.

[0010] Furthermore, the notch is square.

[0011] Furthermore, the cross section of the guide limiter is in the shape of an I. The guide limiter in the shape of an I is structurally stable and can limit the notch in four directions, i.e., east, west, south, and north.

[0012] In order to improve the vertical bearing capacity of the combined limiting bracket, further, the spring assembly includes 4 groups of springs arranged in a 2*2 matrix.

[0013] Furthermore, a pipe support for supporting the pipeline is provided on the upper surface of the pipe support bottom plate.

[0014] In order to enhance the stability of the combined limiting bracket, a reinforcing structure is further included, and the reinforcing structure is respectively welded to the upper surface of the bottom plate of the pipe support and the side surface of the pipe support.

[0015] Compared with the prior art, the advantages of the present invention are: by opening a notch on the bottom plate of the pipe support that interacts with the guide limit piece, the guide limit piece is set in the notch. Since there is no need to set the guide limit piece around the bottom plate of the pipe support, the floor space and installation space of the combined limit bracket are reduced; when the bottom surface of the space that can be provided during actual installation is a rectangle, without changing other components of the combined limit bracket, it is only necessary to set the bottom plate of the pipe support to a rectangular plate and open a notch on the rectangular plate, so that the combined limit bracket can be used normally when the length of the installation space is limited in a certain direction; in addition, since the guide limit piece is located in the notch at the four corners or four sides and will not completely block the spring assembly, it is convenient for the installer to take out the positioning block in the spring and see the displacement scale of the spring.

[0023] The present invention is further described in detail below with reference to the accompanying drawings.

[0024] Embodiment 1

[0025] like Figures 4 to 6 The figure shows a preferred embodiment of the combined limit bracket in the present invention, which includes a support base plate 1, a pipe support base plate 2, a spring assembly 3, a pipe support 7 and a guide limit member 4. The bottom of the spring assembly 3 is fixed on the support base plate 1; the pipe support base plate 2 is a rectangular plate, which is movably arranged on the spring assembly 3, and the pipe support base plate 2 can move horizontally relative to the spring assembly 3; the pipe support 7 is welded and arranged on the upper surface of the pipe support base plate 2, and is used to support the pipeline 6. The four top corners of the pipe support base plate 2 are provided with inwardly recessed notches 21; the number of the guide limit members 4 is the same as the number of the notches 21, the bottom ends of the guide limit members 4 are fixed on the support base plate 1, and the top ends of the guide limit members 4 are respectively limited in the notches 21, and the guide limit members 4 can limit the movement of the pipe support base plate 2 in the horizontal direction.

[0026] In order to make the notch 21 have the same effective area as the guide limiter 4 in all directions, the notch 21 is square; the cross section of the guide limiter 4 is an "I" shape, and the "I"-shaped guide limiter 4 has a more stable structure and can also interact with the two vertical side walls of the notch 21 at the same time. According to actual engineering needs, in order to limit the movement of the pipe support bottom plate 2 in a certain direction, the guide limiter 4 can be against the side wall corresponding to the notch 21; on the contrary, in order to allow the pipe support bottom plate 2 to move a certain distance in a certain direction, a suitable distance can be reserved between the guide limiter 4 and the side wall of the notch 21.

[0027] In order to improve the vertical bearing capacity of the combined limit bracket, the spring assembly 3 includes 4 groups of springs arranged in a 2*2 matrix. In addition, the combined limit bracket also includes a reinforcement structure 5, which is welded to the upper surface of the pipe support bottom plate 2 and the side of the pipe support 1, respectively, for the overall reinforcement of the combined limit bracket. The reinforcement structure can select components of different specifications, such as channel steel, steel, etc., according to the different load sizes of the bracket, so as to make the combined limit bracket more widely used.

[0028] The area of ​​the notch 21 on the pipe support bottom plate 2 and the size of the guide limiter 4 corresponding to the notch 21 can be calculated based on the actual horizontal load to be borne.

[0029] When the notch 21 on the bottom plate 2 of the pipe support in this embodiment is small in area, the notch 21 can be directly Figure 2 The four top corners of the middle tube support bottom plate 2 are cut (not shown in the figure). At this time, the installation range of the guide limiter 4 will not exceed the range before the tube support bottom plate 2 is cut, which will greatly save the installation space of the combined limit bracket.

[0030] In this embodiment, when the notch 21 on the bottom plate 2 of the pipe support is relatively large, the notch 21 cannot be directly Figure 2 The pipe support bottom plate 2 is cut from the pipe support bottom plate 2, and the area of ​​the pipe support bottom plate 2 needs to be increased. Figure 6 As shown, the pipe support bottom plate 2 is a rectangle before cutting, and the short side of the rectangle is as long as Figure 2 The sides of a square are equal in length, and the long side of a rectangle is longer than Figure 2 The side length of the square in the middle. After the guide limiter 4 is installed in the notch 21 at the four top corners of the tube support bottom plate 2, the range of the guide limiter 4 will not exceed the width of the rectangle, thereby saving the installation space in the width direction of the tube support bottom plate 2, so the combined limiter bracket can adapt to the installation space with a rectangular bottom surface; in other words, the combined limiter bracket of this embodiment does not change other components, but only optimizes the shape of the tube support bottom plate 2 to transform the original square installation bottom surface into a rectangular installation bottom surface, so that the combined limiter bracket can be used normally in a space with a limited length in a certain direction in the horizontal plane. In this solution, the length of the short side of the rectangular bottom surface of the installation space cannot be too short, and at least it can accommodate the spring assembly 3.

[0031] Embodiment 2

[0032] The difference from the first embodiment is that the inwardly recessed notches 21 are arranged on two opposite sides of the tube support bottom plate 2. Figure 7 As shown, the bottom plate of the pipe support is a rectangular plate, and two inwardly recessed notches 21 are provided on each long side of the rectangular plate. Similarly, two inwardly recessed notches 21 may also be provided on each short side of the rectangular plate.
