Description

A fire protection pipe joint installation angle positioning device

Technical Field

The utility model relates to the technical field of building installation, in particular to the technical field of auxiliary positioning devices for building pipeline installation, and specifically to a fire protection pipeline joint installation angle positioning device.

Background Art

Fire-fighting pipes are inevitably installed in buildings. The most densely installed and complex areas are basements or the tops of underground garages. The pipes installed on the tops of underground garages include fire-fighting pipes, water supply pipes, and sewer pipes. Before the building installation, there will be detailed drawings of the pipe location and installation. However, due to the large number of pipes, there are also requirements for the placement of pipes of different diameters. Therefore, how to reliably and airtightly connect pipes in different areas and positions through elbows (elbows are also called joints) is the biggest difficulty in pipe installation.

The prior art was searched by the keyword "pipeline installation" and two relevant prior arts were obtained.

Prior art 1: A Chinese invention with a publication number of CN107606314A discloses a pipe installation assembly, which is formed by splicing semicircular ring pipes to form upper and lower integral assembly through holes for installing pipes, but it cannot solve the problem of spatial positioning and installation between pipes.

Prior art 2: A Chinese invention with a publication number of CN111963770A discloses a pipeline positioning device for solving the problem that in existing water supply and drainage projects, pipeline construction is generally carried out by manually correcting the height and position of the pipeline, and then fixing it with a positioning device. This method consumes a lot of manpower and material resources during construction and has low work efficiency.

The present application focuses on solving the problem of spatial positioning of joints between two adjacent pipes located in non-same horizontal planes during the installation of water supply and drainage pipes and fire protection pipes, so as to avoid the problem of inability to install due to axial or angular misalignment between two joints that need to be connected to each other.

Utility Model Content

In order to solve the problem in the prior art that pipe joints in different horizontal or longitudinal planes are difficult to position or align during the installation of large-diameter metal pipes for fire protection and water supply and drainage, the present application provides a fire protection pipe joint installation angle positioning device, which is used to accurately position the pipe joint according to a preset angle or angle specified in the drawing, thereby solving the problem of difficulty in installation caused by angle deviation or position misalignment between two joints to be connected due to inaccurate positioning.

In order to fully understand the technical innovation and good practicality of the utility model in the process of pipeline installation, the problems existing in the process of pipeline joint installation are briefly described as follows:

Fire protection pipes and water supply and drainage pipes are usually large-diameter metal pipes. When installing, auxiliary devices are indispensable for support and positioning. The arrangement and installation of pipes are carried out according to the specifications of the design drawings, but because the installation of metal pipes is ceiling-mounted, the pipes need to be suspended from the top of the building and fixed and airtightly connected. The fixation of pipes is achieved by hangers with expansion bolts, but the connection between pipes requires joints. The joints mentioned here refer to pipes with a certain bending angle, usually called "elbows". The inner diameter of the joint is adapted to the outer diameter of the pipe and is connected by threads. Since the joint can rotate relative to the pipe or rotate with the unfixed pipe, the spatial angle of the joint cannot be effectively fixed. Once the pipe is fixed, if there is an angle deviation when connecting the joint, it is necessary to reconnect the joint or loosen the pipe to adjust the angle. However, no matter which method is used, the human labor and time costs are huge.

In the prior art, the method used to solve this problem is sequential installation, that is, the pipelines to be installed are installed one by one and sequentially according to the requirements of the drawings, so as to avoid the problem that adjacent joints cannot be connected due to spatial errors in angles or positions. However, sequential installation will bring new problems. First, it is inefficient and cannot achieve synchronous construction in different areas. Second, errors in joint connections will be superimposed during sequential installation. The longer the installation length, the more likely it is that the pipeline installation position will deviate from the preset position or the position planned in the drawings. This is particularly obvious when multiple layers of pipelines need to be installed in a stacked manner.

In summary, when installing pipelines, as long as the space angle reserved for the pipeline joints can be accurately determined, the problem of pipeline docking errors can be solved, and construction in multiple areas can be achieved simultaneously, greatly improving the efficiency of pipeline installation.

In order to achieve the above purpose, the technical solution adopted in this application is:

A fire pipe joint installation angle positioning device comprises a sleeve for detachably fixing on the fire pipe, the sleeve is rotatably connected with an angle indicating disk and a positioning mechanism, the positioning mechanism comprises a swivel rotatably mounted on the fire pipe, the swivel is fixedly mounted with a lifting mechanism, and the lifting mechanism is fixedly provided with a positioning plate for being flush with the end face of the joint and a pointer for being in contact with the angle indicating disk.

In order to more intuitively determine the spatial deflection angle of the joint, preferably, the angle indicating disk includes a hollow disk body rotatably arranged on the sleeve, the outer shell of the hollow disk body is made of transparent material, a double-sided angle dial is fixedly arranged inside the hollow disk body, and a first steel ball aligned with the zero scale line of the angle dial is suspended inside the hollow disk body by a flexible rope, and a second steel ball can roll freely in the hollow disk body.

In order to facilitate the fixation of the sleeve, preferably, a plurality of shrinkage seams are axially arranged at one end of the sleeve away from the positioning plate, and the shrinkage seams divide the sleeve into a plurality of tail pieces distributed in a circular array, and the thickness of the tail piece gradually increases from the end surface to one side of the sleeve and forms an arc-shaped inclined surface on the outer wall, and a thread for detachably fixed connection with the cap body is arranged on the circumferential side wall of the sleeve close to the tail piece, and the inner wall of the cap body has a convergent section which fits with the arc-shaped inclined surface and presses the tail piece against the outer wall of the fire protection pipe.

Preferably, a plurality of radially arranged handles are fixedly provided on the outer side wall of the cap body.

Preferably, the lifting mechanism includes a column fixedly mounted on a swivel, with slide grooves being arranged on opposite sides of the column, and a U-shaped slide slidably mounted on the column, with a positioning plate for being flush with the end face of the joint and a pointer for being fitted with the angle indicator plate being arranged on opposite sides of the U-shaped slide.

Preferably, the U-shaped slide is threadedly connected with an adjusting screw for adjusting the relative position of the U-shaped slide and the column.

Preferably, a plurality of balls are embedded and installed between the rotating ring and the sleeve.

Preferably, at least one reinforcing rib is fixedly disposed between the positioning plate and the U-shaped slide seat.

Preferably, a locking screw for fixing the relative position between the swivel and the sleeve is provided on the swivel.

Beneficial effects:

The utility model can accurately locate the spatial deflection angle of the pipe joint, so that the reserved pipe joints in the pipeline installation process can be positioned and fixed according to the angle specified in the drawing, thereby solving the problem of position or angle misalignment between the reserved joints.

The utility model solves the problem of misalignment between joints by spatially angularly positioning the pipe joints, so that pipes in different areas can be constructed and installed simultaneously without the need for the existing sequential installation, thereby greatly improving the installation efficiency of building pipes.

Embodiment 1:

Referring to Figures 1 and 2 of the specification, a fire pipe joint installation angle positioning device is shown, including a sleeve 9 for detachably fixedly sleeved on the fire pipe 1, and the sleeve 9 is rotatably connected with an angle indicating disk 3 and a positioning mechanism, and the positioning mechanism includes a swivel 4 rotatably sleeved on the fire pipe 1, and a lifting mechanism is fixedly installed on the swivel 4, and a positioning plate 11 for flushing with the end surface of the joint 12 and a pointer 61 for fitting with the angle indicating disk 3 are fixedly provided on the lifting mechanism.

Working and structural principle:

There are two application scenarios for positioning the joint 12 of the utility model. One is that the pipeline 1 is fixed, and the joint 12 is installed on the fixed pipeline 1 and the other connection end of the joint 12 is fixed according to a preset spatial angle; the other is that the pipeline 1 is movable, and the joint 12 is fixedly connected to the pipeline 1 and the other connection end of the joint 12 is fixed according to a preset spatial angle.

First, the installation of the joint 12 on the movable pipe 1 is taken as an example for explanation: since the pipe 1 has not been fixed yet and the pipe 1 is a rotating body structure, after the joint 12 is fixedly connected to the pipe 1, the angle of the joint 12 will change as the pipe 1 rotates. For this installation scenario, the pipe 1 is first conventionally fixed to prevent the pipe 1 from rotating or rolling, and the fixed position should be carried out according to the construction drawings; then, the angle positioning device provided in this embodiment is installed on the pipe 1 and fixed in the manner shown in Figure 1 or Figure 2, and the angle indicator disk 3 is rotated so that the O scale line of the angle indicator disk 3 remains in the vertical direction, and then the joint 12 is installed on the end of the pipe 1, but there is no need to tighten it. At this time, it is just pre-installed for angle positioning; it is worth noting that the existing level bubble structure can be used to visually check whether the 0 scale line of the angle indicator disk 3 is in the vertical direction. Then adjust the lifting mechanism so that the positioning plate 11 fits with the end face of the other connecting end of the connector 12, and rotate the connector 12 and the swivel 4 at the same time until the position of the pointer 61 corresponds to the angle of the angle indicator disk 3 and is consistent with the preset angle. For example, if the deflection angle of the connector 12 is 25°, then you only need to rotate the connector 12 and the swivel 4 synchronously so that the pointer 61 is flush with the 25° on the angle indicator disk 3. At this time, the angle between the axis of the end face of the other connecting end of the connector 12 and the vertical plane is 25°. After completing the above positioning, in order to ensure that the current angle is still maintained when the connector 12 is officially installed, it is necessary to use a marking pen to draw lines on the connector 12 and the pipe 1, preferably two lines. When tightening and installing, as long as the two marked lines are aligned, the spatial angle of the connector 12 can be guaranteed to be the preset accurate angle, thereby avoiding the problem of angle misalignment and inability to dock. After completing the marking, the connector 12 and the angle positioning device can be removed one after another.

Secondly, for the installation of the fixed pipe 1, for example, the other end of the pipe 1 to which the joint 12 is to be installed has been fastened, then the angle positioning device provided in this embodiment can be directly installed on the pipe 1, and the positioning mark is made according to the above method, and then the joint 12 and the angle positioning device are removed in sequence. The above whole process can be completed by a single person, which is very convenient and practical, and avoids the problem of angle misalignment and inability to connect adjacent joints 12 when docking, and the need to use sequential connection, resulting in low efficiency.

Embodiment 2:

In order to more intuitively determine whether the 0 scale of the angle indicator disk 3 itself is aligned with the vertical direction, so as to accurately locate the spatial deflection angle of the joint 12, in this embodiment, the angle indicator disk 3 includes a hollow disk body rotatably set on the sleeve 9, the outer shell of the hollow disk body is made of transparent material, and a double-sided angle dial 33 is fixedly arranged inside the hollow disk body, and a first steel ball 31 aligned with the zero scale line of the angle dial 33 is suspended inside the hollow disk body by a flexible rope, and a second steel ball 32 that can roll freely in the hollow disk body.

Specifically referring to Figures 3 to 5, since the first steel ball 31 is suspended by a thin rope at the 12 o'clock direction and above the 0 scale line, when the 0 scale line is not in a vertical state, there will be a spatial angle a between the 0 scale line and the suspension rope of the first steel ball 31. The larger the angle a is, the greater the deviation between the 0 scale line and the vertical direction is. When the thin rope suspending the first steel ball 31 coincides with the 0 scale line, it means that the 0 scale line of the angle dial 33 is in a vertical state at this time. At the same time, observe whether the second steel ball 32 is at the 180° position to facilitate angle correction. Since the angle indicator disk 3 is circular, the second steel ball 32 will naturally be at the bottom position under the action of gravity, so that the operator can quickly and intuitively grasp the angle state of the angle indicator disk 3.

Embodiment 3:

This embodiment is a further structural optimization based on any of the above embodiments. In order to facilitate the fixing of the sleeve 9, in this embodiment, the sleeve 9 is provided with a plurality of contraction seams along the axial direction at one end away from the positioning plate 11. The contraction seams divide the sleeve 9 into a plurality of tail pieces 91 distributed in a circumferential array. The tail piece 91 gradually increases in thickness from the end surface to one side of the sleeve 9 and forms an arc-shaped inclined surface on the outer wall. The sleeve 9 is provided with a thread 92 for detachably fixing and connecting with the cap body 2 on the circumferential side wall close to the tail piece 91. The inner wall of the cap body 2 has a convergence section 22 that fits with the arc-shaped inclined surface and presses the tail piece 91 against the outer wall of the fire protection pipe 1. As shown in Figures 6-7 of the specification, as the cap body 2 and the sleeve 9 are tightened, the tail piece 91 will be continuously squeezed in the radial direction under the action of the convergence section 22 on the arc-shaped inclined surface of the tail piece 91, so that the tail piece 91 is tightly fitted on the circumferential side wall of the sleeve 9, thereby facilitating quick disassembly and assembly.

In order to facilitate the disassembly, assembly and fastening of the cap body 2 , a plurality of radially arranged handles 21 are fixedly provided on the outer side wall of the cap body 2 . When disassembling or assembling, it is only necessary to hold the handles 21 and screw the cap body 2 .

In this embodiment, the lifting mechanism includes a column 5 fixedly mounted on a swivel 4, and a slide groove 51 is provided on opposite sides of the column 5, and a U-shaped slide 6 is slidably mounted on the column 5, and a positioning plate 11 for flushing with the end surface of the joint 12 and a pointer 61 for fitting with the angle indicator plate 3 are respectively provided on opposite sides of the U-shaped slide 6.

In this embodiment, the U-shaped slide 6 is threadedly connected with an adjusting screw 7 for adjusting the relative position of the U-shaped slide 6 and the column 5 .

In this embodiment, a plurality of balls 51 are embedded and installed between the rotating ring 4 and the sleeve 9 .

In this embodiment, at least one reinforcing rib 10 is fixedly disposed between the positioning plate 11 and the U-shaped sliding seat 6 .

In this embodiment, a locking screw 8 for fixing the relative position between the swivel 4 and the sleeve 9 is provided on the swivel 4 .

The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
