Description

Technical Field

[0001] This utility model relates to the field of sewage pipeline technology, and in particular to a sewage pipeline expansion joint fixing device. Background Technology

[0002] The expansion joint fixing device for sewage pipelines is a device used to ensure the stability and sealing of expansion joints in sewage pipeline systems. Expansion joints are used to absorb these displacements and protect the integrity of the pipeline system, while the expansion joint fixing device further ensures that the expansion joints can move freely within the allowable range while maintaining their fixed position and sealing.

[0003] However, the aforementioned patents have certain shortcomings in practical use. On the one hand, many fixing devices have relatively simple structures and cannot effectively ensure that the expansion joint can move freely within the allowable range while maintaining its fixed position, resulting in insufficient stability of the expansion joint and potentially affecting the normal operation of the pipeline system. On the other hand, some existing fixing devices are difficult to adapt to the installation position of sewage pipeline expansion joints, which often requires additional adjustments or accessories during the actual installation process. This increases the complexity and cost of installation and reduces work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that it is impossible to effectively ensure that the expansion joint can move freely within the allowable range while maintaining its fixed position, and it is difficult to adapt to the installation position of the expansion joint in sewage pipelines.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sewage pipe expansion joint fixing device, including a fixing seat, an auxiliary mechanism provided on one side of the fixing seat, the auxiliary mechanism including an auxiliary groove opened on one side of the fixing seat, a plurality of fixing frames installed on the inner wall of the auxiliary groove, a plurality of auxiliary holes opened on the fixing frames, a spring-loaded telescopic rod fixedly connected to the inner wall of the auxiliary hole, a limiting block fixed at one end of the spring-loaded telescopic rod, and one end of the limiting block contacting the inner wall of the auxiliary groove;

[0006] An adjustment mechanism is provided at one end of the fixed frame. The adjustment mechanism includes an adjustment groove opened at one end of the fixed frame, an adjustment column installed on the inner wall of the adjustment groove, a limiting rod threadedly connected to one side of the fixed frame, and adjustment holes evenly distributed on one side of the adjustment column. The inner wall of one of the adjustment holes is threadedly connected to one end of the limiting rod.

[0007] Furthermore, one end of the adjusting column is provided with a fixing mechanism, which includes a fixing groove opened at one end of the adjusting column. The inner wall of the fixing groove is connected to a fixing ring one via a rotating rod. The fixing ring one and the adjusting column are provided with multiple limiting holes. The inner walls of two of the limiting holes are threaded with limit rods. One side of the fixing ring one contacts a fixing ring two, and multiple fixing bolts are threaded on the fixing ring two.

[0008] Furthermore, sealing gaskets are provided on the inner walls of fixing ring two and fixing ring one, and the sealing gaskets are adapted to the inner walls of fixing ring two and fixing ring one.

[0009] Furthermore, one side of the sealing gasket contacts a sewage pipe expansion joint.

[0010] Furthermore, an anti-slip pad is provided on one side of the fixing base, and the anti-slip pad is connected to the fixing base by a mounting bolt.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The auxiliary mechanism installed on the fixed base in this application not only provides elastic support and restricts displacement for the sewage pipe expansion joint, but also prevents excessive displacement, thereby ensuring that the sewage pipe expansion joint can move freely within the allowable range while maintaining its relatively fixed position. This effectively improves the stability of the sewage pipe expansion joint and ensures the normal operation of the pipeline system. At the same time, the fixing mechanism installed on the adjusting column can not only adapt to sewage pipe expansion joints of different sizes and shapes, but also adjust the angle according to the installation position without the need for additional adjustments or accessories, simplifying the installation process, reducing installation costs, and improving work efficiency.

[0013] 2. The adjustment mechanism in the fixing frame of this application can not only be flexibly adjusted according to the installation position of the sewage pipe expansion joint, but also achieve precise adjustment of the fixing frame position, thereby better adapting to the installation requirements of the expansion joint and further enhancing the stability of the expansion joint in different positions. At the same time, the sealing gaskets set in fixing ring one and fixing ring two can not only improve the sealing performance of the sewage pipe expansion joint connection and prevent sewage leakage, but also adapt to the slight unevenness of the expansion joint surface, further enhancing the adaptability of the fixing device to different expansion joints and ensuring the convenience and reliability of installation.

[0029] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0030] like Figure 1-7 As shown, a sewage pipe expansion joint fixing device is disclosed, including a fixing base 1. An anti-slip pad 7 is provided on one side of the fixing base 1. The anti-slip pad 7 is threadedly connected to the fixing base 1 by a mounting bolt 8. An auxiliary mechanism 2 is provided on one side of the fixing base 1. The auxiliary mechanism 2 includes an auxiliary groove opened on one side of the fixing base 1. Two fixing frames 201 are installed on the inner wall of the auxiliary groove. Two auxiliary holes are opened on the fixing frames 201. A spring-loaded telescopic rod 202 is fixedly connected to the inner wall of the auxiliary holes. The spring-loaded telescopic rod 202 is composed of a telescopic rod one (small diameter), a telescopic rod two (large diameter), and a spring. One end of the telescopic rod one is nested and connected to the inner wall of the telescopic rod two through a sealing block or sealing gasket. The spring is fitted outside the telescopic rod one and the telescopic rod two. A limiting block 203 is fixed to one end of the spring-loaded telescopic rod 202 for auxiliary limiting of the fixing frame 201. One end of the limiting block 203 is in contact with the inner wall of the auxiliary groove.

[0031] An adjustment mechanism 3 is provided at one end of the fixed frame 201. The adjustment mechanism 3 includes an adjustment groove opened at one end of the fixed frame 201, an adjustment column 301 installed on the inner wall of the adjustment groove, a limiting rod 302 threadedly connected to one side of the fixed frame 201, and adjustment holes evenly distributed on one side of the adjustment column 301. The inner wall of one of the adjustment holes is threadedly connected to one end of the limiting rod 302. Example 2

[0032] like Figure 1-7As shown, this embodiment is obtained by adding technical features such as fixing mechanism 4 on the basis of embodiment 1. The remaining technical features are the same as those in embodiment 1, and the similarities will not be repeated here. The technical features that are different from those in embodiment 1 are: a fixing mechanism 4 is provided at one end of the adjusting column 301. The fixing mechanism 4 includes a fixing groove opened at one end of the adjusting column 301. The inner wall of the fixing groove is connected to a fixing ring 401 through a rotating rod. The fixing ring 401 and the adjusting column 301 are provided with multiple limiting holes. The fixing ring 401 has two limiting holes and the adjusting column 301 has four limiting holes. The inner walls of the two limiting holes are threaded with limit rods 402. One side of the fixing ring 401 contacts a fixing ring 403. Two fixing bolts 404 are threaded on the fixing ring 403.

[0033] A sealing gasket 5 is provided on the inner wall of the second fixing ring 403 and the first fixing ring 401. The sealing gasket 5 is adapted to the inner wall of the second fixing ring 403 and the first fixing ring 401. One side of the sealing gasket 5 contacts the sewage pipe expansion joint 6.

[0034] The working principle of the overall technical solution formed by the above embodiments is as follows: When fixing, the operator fixes the fixing seat 1 to the designated position by the anti-slip pad 7 and the mounting bolt 8, which provides the overall stability of the device. The anti-slip pad 7 set on the fixing seat 1 enhances the friction and prevents the fixing seat 1 from sliding, ensuring that the device is firmly connected to the support surface. Then, the operator loosens the limiting rod 302 connected to the threaded connection of the fixing frame 201, moves the adjusting column 301 to the required position in the adjusting groove of the fixing frame 201, inserts the limiting rod 302 into the adjusting hole of the corresponding adjusting column 301 and tightens it, which makes it easy to fix the position of the adjusting column 301. The extension length and angle of the fixing frame 201 can be flexibly adjusted to adapt to different installation position requirements.

[0035] After adjustment, the fixed frame 201 installed in the auxiliary groove of the fixed seat 1 is moved and adjusted according to the position of the sewage pipe expansion joint 6. During the movement, the spring-loaded telescopic rod 202 and the limiting block 203 on the fixed frame 201 interact with each other and can provide auxiliary restriction to the fixed frame 201. When the sewage pipe expansion joint 6 is displaced due to temperature changes or vibration, the spring-loaded telescopic rod 202 on the fixed frame 201 absorbs the displacement energy through elastic deformation, and the limiting block 203 contacts the inner wall of the auxiliary groove to limit the displacement amplitude, ensuring that the sewage pipe expansion joint 6 moves within the allowable range while maintaining a relatively fixed position.

[0036] Then, the staff adjusted the positions of the first fixed ring 401 and the second fixed ring 403 according to the installation of the sewage pipe expansion joint 6. During the adjustment, the limiting rod 402 that is threadedly connected to the adjusting column 301 of the first fixed ring 401 was removed, and the fixing bolt 404 that is threadedly connected to the first fixed ring 401 and the second fixed ring 403 was removed. The angle of the first fixed ring 401 and the second fixed ring 403 was adjusted. After the adjustment, the limiting rod 402 was passed through the limiting hole of the first fixed ring 401 and the adjusting column 301 again to ensure that the clamping angle is fixed.

[0037] After adjustment, the expansion joint 6 of the sewage pipe is made to fit the sealing gasket 5 set in the first fixing ring 401 and the second fixing ring 403 to the surface of the expansion joint, adapting to its size and surface unevenness, and preventing sewage leakage. Then, tighten the fixing bolt 404 to make the first fixing ring 401 and the second fixing ring 403 clamp the expansion joint 6 of the sewage pipe.
