Description

Technical Field

[0001] The present application relates to the technical field of pipeline connection, and in particular to a socket-type steel pipe installation auxiliary device. Background Art

[0002] At present, the main installation method of socket-and-spigot pipes is mechanically assisted manual installation, which is mainly assisted by cranes or excavators. A large excavator is used to push the bottom of the spigot pipe directly into the socket pipe, and the installation angle is adjusted manually during the process. For example, ordinary socket-and-spigot pipes require manual cooperation with excavators for construction in trenches, and large-scale mechanical installation is inconvenient, time-consuming and labor-intensive.

[0003] Therefore, most of the time, a jack is used to connect the two socket pipes to be connected, and then the two socket pipes are pulled close to each other to complete the connection. For example, the Chinese patent CN205496924U describes that it is used to connect ductile iron pipes. Since the ductile iron pipe has a thick wall and a heavy weight, it is necessary to ensure that the connection between the two ends of the jack and its outer surface is subject to a large force. Generally, welding is used for connection, and the connection is cut off after the connection is completed; or a full circle of clamps is used for connection, which needs to be disassembled after completion. The connection process of the above two methods is relatively time-consuming and labor-intensive.

[0004] In addition, the current socket-type steel pipe has a thinner wall thickness and lighter weight than ductile iron pipes, so there is no need to ensure the stability of the connection. The problem it faces is how to facilitate the rapid connection of auxiliary installation equipment and quickly disassemble it after the connection is completed to speed up the construction progress.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The embodiment of the present application provides a socket-type steel pipe installation auxiliary device to solve the problem that the auxiliary equipment used for installing ductile iron pipes in the related art is not convenient for quick installation and disassembly.

[0029] Because the steel pipe is light and thin, the auxiliary equipment originally used to install the ductile iron pipe will affect the shape of the steel pipe and even cause deformation. In addition, the auxiliary equipment is relatively cumbersome during installation and removal, which affects the construction progress. Therefore, the solution of this application is proposed.

[0030] See also Figure 1-Figure 3 , a socket-type steel pipe installation auxiliary equipment, comprising:

[0031] Two electromagnetic generating components 1, each of which has a steel pipe-fitted arc surface 2; a mounting base 3 and a magnetic control switch are provided on the electromagnetic generating component 1;

[0032] The telescopic member 4 has two ends connected to the two electromagnetic generating assemblies 1 through the mounting base 3, and is used to telescope in the axial direction of the steel pipe. The number of the telescopic member 4 can be two or one.

[0033] Since the two electromagnetic generating components 1 both have an arc-shaped surface 2 that fits the steel pipe; the electromagnetic generating component 1 is provided with a mounting base 3 and a magnetic control switch; the two ends of the telescopic component 4 are respectively connected to the two electromagnetic generating components 1 through the mounting base 3, and it is used to telescope in the axial direction of the steel pipe; when in use, an electromagnetic generating component 1 is directly set on the top of the two steel pipes to be connected, and then the magnetic control switch is used to generate electromagnetic force and connect with the steel pipe; then the telescopic component 4 is installed, and the connection of the two steel pipes is completed by the contraction of the telescopic component 4; after the connection is completed, the magnetic force is cancelled by the magnetic control switch, so that it can be quickly connected and separated from the steel pipe, which is convenient for the installation of the next section of the steel pipe and speeds up the construction progress; the above socket-type steel pipe installation auxiliary equipment is particularly suitable for construction situations where the steel pipe does not require stable connection due to its thin wall and light weight, and the connection speed needs to be accelerated.

[0034] Of course, when in use, the entire device may be assembled first, and then the travel of the telescopic member 4 may be extended to the maximum, and then the two electromagnetic generating components 1 may be magnetically connected to the corresponding steel pipes respectively.

[0035] In some preferred embodiments, the specific structure of the electromagnetic generating assembly 1 is described as follows:

[0036] The first type, the electromagnetic generating component 1 includes a single arc plate 100, and an arc-shaped electromagnet sheet is arranged inside the arc plate 100. The inner surface of the arc plate 100 is a steel pipe-fitting arc surface 2, and is used to contact the outer surface of the top of the steel pipe; the outer surface of the arc plate 100 is connected to the mounting base 3.

[0037] In this case, the use of the arc plate 100 can increase the contact area with the steel pipe, thereby avoiding the influence of the single-point connection on the shape of the steel pipe, and at the same time also increases the area of ​​the magnetic connection and improves the connection strength.

[0038] Further, to increase the connection area, there is a second form:

[0039] The electromagnetic generating assembly 1 includes a connecting member 101, which is located above the telescopic member 4 and has an extending direction perpendicular to the telescopic direction of the telescopic member 4; both ends of the connecting member 101 in the extending direction are respectively connected to connecting blocks 103;

[0040] An arc plate 100 is provided at the bottom of the connecting block 103 , and the inner surface of the arc plate 100 is a steel pipe fitted arc surface 2 ; an arc-shaped electromagnet sheet is provided inside the arc plate 100 ; the two arc plates 100 and the connecting piece 101 form a claw structure.

[0041] In this way, it not only contacts the top of the steel pipe, but also contacts the two sides of the steel pipe to improve the connection strength and avoid affecting the shape of the steel pipe.

[0042] Furthermore, in order to improve the versatility and compatibility of the socket-type steel pipe installation auxiliary equipment, there may be situations where steel pipes of different sizes need to be connected during actual use, so the following settings are made:

[0043] Setting 1: The connecting member 101 includes a plurality of connecting bolts; a plurality of mounting holes 102 for mounting the connecting bolts are provided on the connecting block 103, and the connecting bolts pass through the mounting holes 102 to connect the two connecting blocks 103.

[0044] In this solution, the distance between the two arc-shaped plates 100 is changed by adjusting the nuts on the connecting bolts, thereby adapting to steel pipes of different sizes.

[0045] Setting 2: The connecting member 101 includes a plurality of elastic connecting ropes, and both ends of the elastic connecting ropes are fixedly connected to the corresponding connecting blocks 103 respectively.

[0046] In this solution, when in use, only two arc-shaped plates 100 need to be installed and connected at corresponding positions, and the elastic connecting rope between them changes with the distance. This avoids the step of adjustment, speeds up the installation process, and saves time.

[0047] Furthermore, in order to strengthen the connection with the outer surface of the steel pipe, in the axial direction of the steel pipe, the wall thickness of the arc plate 100 gradually increases from the end away from the steel pipe connection port to the end close to the steel pipe connection port.

[0048] Alternatively, an elastic anti-skid sheet or anti-skid lines are provided on the steel pipe fitting arc surface 2. In these two forms, even if the connection of the arc plate 100 is not stable enough and there is movement, it will be limited after moving for a period of time.

[0049] In some preferred embodiments, the mounting base 3 has a mounting surface in the axial direction of the steel pipe, and the mounting surface is provided with a threaded mounting hole; both ends of the telescopic member 4 are fixedly connected with a connecting plate, and the connecting plate is provided with a through hole corresponding to the threaded mounting hole; the connecting plate is connected by fastening bolts penetrating the threaded mounting hole and the through hole. In this way, the telescopic member 4 can be detachably mounted.

[0050] The telescopic member 4 is a hydraulic telescopic rod or a rope telescopic machine or the like.

[0051] Beneficial effects of this application:

[0052] 1. When in use, directly set an electromagnetic generating assembly 1 on the top of the two steel pipes to be connected, and then use the magnetic control switch to generate electromagnetic force to connect with the steel pipe; then install the telescopic part 4, and complete the connection of the two steel pipes by contracting the telescopic part 4; after the connection is completed, use the magnetic control switch to cancel the magnetic force, so that it can be quickly connected and separated from the steel pipe, which is convenient for the installation of the next section of the steel pipe and speeds up the construction progress; the above socket-type steel pipe installation auxiliary equipment is particularly suitable for steel pipes that do not require stable connection due to their thin walls and light weight, and need to speed up the connection speed. Of course, when in use, you can also assemble the entire equipment first, then extend the travel of the telescopic part 4 to the maximum, and then magnetically connect the two electromagnetic generating assemblies 1 to the corresponding steel pipes respectively.

[0053] Second, the bottom of the connecting block 103 is provided with an arc plate 100, the inner surface of the arc plate 100 is a steel pipe fitting arc surface 2; an arc-shaped electromagnet sheet is provided inside the arc plate 100; the two arc plates 100 form a claw structure with the connecting piece 101. In this way, it not only contacts the top of the steel pipe, but also contacts the two sides of the steel pipe to improve the connection strength and avoid affecting the shape of the steel pipe.

[0054] 3. The connecting member 101 includes a plurality of connecting bolts; a plurality of mounting holes 102 for mounting the connecting bolts are provided on the connecting block 103, and the connecting bolts pass through the mounting holes 102 to connect the two connecting blocks 103. In this solution, the distance between the two arc-shaped plates 100 is changed by adjusting the nuts on the connecting bolts, so as to adapt to steel pipes of different sizes.
