DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Pipeline installation auxiliary tools generally refer to a series of tools and equipment used to assist in the installation, adjustment and connection of pipelines. These tools are designed to simplify the pipeline installation process, improve efficiency, and ensure installation quality. Municipal drainage pipes are usually composed of longer pipe sections. During installation, pipe clamps are generally required to assist in installation to ensure that the pipes remain in a fixed position during the installation process and avoid unstable or inaccurate installation caused by the movement of the pipe position. In addition, municipal drainage pipes usually need to bear a large weight, especially when buried underground or crossing other structures. Pipe clamps can effectively support the weight of the pipes, reduce the load on the pipes themselves and the flowing medium therein, and improve the stability and safety of the pipes. At present, when the pipe clamps used are fixed on the surface of the drainage pipe, bolts and nuts are usually used for locking. However, the vibration generated by the water flow in the subsequent drainage pipe is transmitted to the bolts, which easily causes the nuts to rotate downward, so that the pipe clamps become loose.

[0026] like Figure 1-Figure 3As shown, the utility model proposes an auxiliary tool for municipal drainage pipe installation, which can greatly improve the firmness of pipe clamp installation. In the auxiliary pipe clamp tool for drainage pipe installation, the clamp edge seal 2 is used to be sleeved on the outer surface of the pipe body 1, and the support seat 3 installed at the bottom of the clamp edge seal 2 ensures the stability of pipe placement and installation. The locking assembly 4 installed on the clamp edge seal 2 is used to avoid the clamp edge seal 2 from being locked loose. The locking assembly 4 includes an extension plate A401 and an extension plate B402 installed at the opening of the clamp edge seal 2. The thickness of the extension plate B402 is greater than the thickness of the extension plate A401, ensuring that the structural strength of the extension plate B402 is high. A bolt nail 403 is threadedly connected between the extension plate A401 and the extension plate B402, and a nut 4031 is sleeved on the outer surface of the bolt nail 403. When the clamp edge seal 2 is normally locked, the clamp edge seal 2 is sleeved on the set position of the drainage pipe, and then the bolt nail 403 is passed downward through the interior of the extension plate A401 and the extension plate B402 in turn, and then the nut 4031 is sleeved on the bolt nail 403 and tightened. A through hole 4032 is provided on the bolt 403, and a hole groove 4021 with an inner diameter smaller than that of the through hole 4032 is provided on one side of the extension plate B402. The hole groove 4021 is composed of a plug-in part and an embedded part with an inner diameter larger than that of the plug-in part. A rubber plug 4023 is provided in the embedded part for sealing one end of the plug-in part, so as to prevent debris from entering the space inside the hole groove 4021 and affecting the installation of the bolt 403. An elastic structure 404 is installed on one side of the extension plate B402 for passing through the hole groove 4021 and inserting into the through hole 4032 on the bolt 403 inside the extension plate B402. When the bolt 403 is fixed to the extension plate A401 and the extension plate B402 with the nut 4031, the through hole 4032 is just connected with the hole slot 4021. At this time, the elastic structure 404, under its own elastic action, causes one end thereof to pass through the through hole 4032 along the path of the hole slot 4021, and is mutually engaged with the bolt 403, thereby effectively preventing the bolt 403 from slightly rotating after being fixed, thereby avoiding the bolt 403 from becoming loose. In addition, the inner diameter of the through hole 4032 is larger than the diameter of one end of the elastic structure 404 adapted to the hole slot 4021, thereby improving the accuracy of inserting one end of the elastic structure 404 into the through hole 4032.

[0027] like Figure 2As shown in the figure, the annular thread groove 4022 opened on one side of the extension plate B402 is located outside the hole groove 4021, and is not interconnected with the mounting hole in the middle of the extension plate B402 for mounting the bolt 403. The elastic structure 404 includes a connecting ring 4041 detachably connected to the annular thread groove 4022, so as to facilitate replacement when the elasticity of the elastic structure 404 fails. A long cylinder 4042 is installed on the connecting ring 4041, and a telescopic spring 4043 is connected inside the long cylinder 4042. One end of the telescopic spring 4043 is connected to a locking rod 4044 arranged in a T shape. The elastic structure 404 as a whole uses the elastic performance and reset function of the telescopic spring 4043 in conjunction with the external force applied to correspondingly change the relative position relationship between the locking rod 4044 and the bolt 403, thereby achieving or canceling the additional restriction effect on the bolt 403.

[0028] like Figure 5 As shown, the clamp edge seal 2 includes a rigid edge seal A201 and a rigid edge seal B202 which are sleeved on the outer surface of the pipe body 1, a round shaft rod 2011 is installed on the rigid edge seal A201, and two connecting sleeves 2021 which are sleeved on both sides of the surface of the round shaft rod 2011 are installed on the rigid edge seal B202. The round shaft rod 2011 and the connecting sleeve 2021 are used to connect the rigid edge seal A201 and the rigid edge seal B202, so that the two have flipping mobility on the basis of forming an integrated assembly, thereby reducing the use of bolts 403 and nuts 4031 compared to the current pipe clamps.

[0029] When using pipe clamps to assist in the installation of drainage pipes, the two semi-arc metal steel rings of the pipe clamps are usually directly fitted on the outer surface of the pipe, thereby increasing corrosion caused by friction and chemical reactions and reducing the service life of the pipe. Figure 4 and Figure 5 As shown, in order to reduce the corrosion damage between the pipe clamp and the pipe, a rubber sheet 203 is installed on the inner wall of the rigid edge seal A201 and the rigid edge seal B202, and a number of uniformly arranged rubber strips 2031 are installed on the rubber sheet 203, and the distance between two adjacent rubber strips 2031 is less than the width of the rubber strip 2031. The rubber sheet 203 is used to isolate the rigid edge seal and the pipe, thereby reducing the corrosion caused by friction and chemical reaction between the two. In addition, the rubber sheet 203 increases the friction force on the inner wall of the pipe clamp, which can prevent the pipe from sliding or shifting during the installation process, and improve the stability and safety of the pipe position. In addition, the elastic characteristics are added in conjunction with the rubber strips 2031 to relieve the stress generated between the drainage pipe and the clamp during the water flow process, thereby reducing the risk of damage to the pipe.

[0030] like Figure 1 and Figure 4As shown, an inner cavity groove is opened at the bottom of the support seat 3, and an upright vertical plate 301 is inserted in the inner cavity groove. A bottom panel is integrally installed at the bottom of the upright vertical plate 301. The upright vertical plate 301 with the bottom panel is replaceable in the present pipe clamp, and can be replaced with upright vertical plates 301 of different heights according to the on-site installation environment of the drainage pipe, thereby improving the adaptability to the installation of drainage pipes with different elevation requirements.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
