Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of optical cable air blowing laying auxiliary devices, and in particular to a pipeline testing device for cable blowing and a manufacturing and use method thereof. Background Art
[0002] Cable blowing is to use high-pressure airflow to blow the optical cable into the silicon core tube. During the blowing process, the silicon core tube may be blocked, which will hinder the cable blowing operation. It is necessary to pull back the optical cable, repair the obstruction point of the silicon core tube, or replace it with another silicon core tube. In order to avoid the optical cable being unable to pass normally due to obstruction in the silicon core tube of the blowing optical cable, which affects the construction work, to avoid rework and unnecessary waste of personnel, machinery and other resources caused by the blockage of the pipeline, and to improve work efficiency and save costs, it is necessary to test and inspect whether the silicon core tube can be used normally before blowing the optical cable. Summary of the invention
[0003] In order to overcome the problem that the optical cable cannot pass normally due to the blockage of the silicon core tube pipeline, the present invention provides a pipeline testing device for cable blowing and a manufacturing and use method thereof. The device can detect the availability of the silicon core tube before the optical cable is blown into the silicon core tube, thereby improving the efficiency of the cable blowing operation and the construction quality.
[0004] The technical solution adopted by the present invention to solve the technical problem is: a pipeline test device for cable blowing, comprising a test section 1 and a traction head 3, wherein the test section 1 is connected to the traction head 3, and one end of the test section 1 connected to the traction head 3 is provided with a connection area 2. The test section 1 is a metal reinforced core optical cable 4, and one end of the metal reinforced core optical cable 4 is bent 180 degrees after removing the outer sheath and loose tube.
[0005] Furthermore, one end of the traction head 3 is fixedly connected to the trial section 1 through the connection area 2, and the other end includes an elastic material, a wrapping layer and a tape, wherein the elastic material is filled in the wrapping layer, and the tape is used to close the wrapping layer and fix the traction head 3.
[0006] Furthermore, the part of the metal reinforcing core optical cable of the trial section 1 without the outer sheath and the loose tube is the reinforcing core 11. The reinforcing core 11 is bent 180° and passes through one end of the wrapping layer. The adhesive tape is tightly wrapped around the reinforcing core 11, the optical cable 4 and the outer side of the end of the wrapping layer to form a connection area 2.
[0007] Furthermore, the elastic material is a high-density sponge, and the wrapping layer is a cotton cloth.
[0008] The present invention also proposes a method for manufacturing a pipeline testing device for cable blowing, which uses local materials and is simple to manufacture, and comprises the following steps:
[0009] Step 1: Select the metal-strengthened optical cable as the test section 1.
[0010] Step 2: Cut off the outer sheath and loose tube of about 10 cm at one end of the optical cable, bend it 180 degrees, and then cut the optical cable, leaving the reinforcing core 11 uncut. The final length of the optical cable 4 is about 30 cm.
[0011] Step 3: Roll the wrapping layer into a cylindrical shape that can accommodate the elastic material, fold one end of the cylindrical wrapping layer in half two to three times, and pierce the wrapping layer with the reinforcing core 4 at a distance of about 5 cm from the end to seal the port of the wrapping layer, and use electrical tape to tightly wrap the port of the wrapping layer at this end and the outer side of the reinforcing core 11 and the optical cable 4, so that the traction head 3 and the test section 1 are firmly connected to prevent them from falling off during the test.
[0012] Step 4: Fill the wrapping layer with elastic material, and wrap the other end of the wrapping layer tightly with electrical tape. Step 5: Wrap electrical tape around the elastic material in the middle to prevent the sponge from falling off. No need to wrap it too tightly.
[0013] The present invention also proposes a method for using a pipeline testing device for cable blowing, comprising the following steps:
[0014] Step 1: Insert the test device into the silicon core tube 10, and the traction head 3 enters the silicon core tube 10 first.
[0015] Step 2: After the trial section 1 completely enters the silicon core tube 10, the optical cable 9 to be laid that has passed through the cable blowing machine 8 is inserted into the silicon core tube 10, and then the working module of the cable blowing machine 8 is tightened to prepare for the start of cable blowing.
[0016] Step 3: Start the air compressor. Driven by the airflow, the test device will move forward quickly. When the test device rushes out of the other end of the silicon core tube 10, start the cable blowing machine 8 to start blowing the optical cable 9 to be laid. If the test device cannot reach the other end of the silicon core tube 10, it means that there is an obstruction in the silicon core tube 10. You can replace it with another hole of the silicon core tube 10 to continue the cable blowing operation and repeat the previous steps, adhering to the principle of testing first and then blowing the cable.
[0017] Beneficial effects:
[0018] 1. The pipeline testing device described in the present invention has air-tightness, easy passability and strong cleaning ability. It can quickly and efficiently check whether the silicon core tube is usable, avoid rework caused by silicon core tube pipeline obstruction, and at the same time remove foreign matter in the pipeline, which is beneficial to the blowing of optical cables and improves the construction quality and operation efficiency of cable blowing.

[0024] The technical solution of the present invention is further explained below in conjunction with specific embodiments and the accompanying drawings.
[0025] Embodiment 1:
[0026] like Figure 1-2 As shown, local materials are used at the construction site, and a metal-reinforced core optical cable 4 is selected as the test section 1. On the one hand, it is convenient to obtain materials and local materials are used. On the other hand, the passability of the pipeline can also be tested. First, the outer sheath and loose tube about 10 cm long at one end of the optical cable 4 are cut off, and the reinforcing core 4 is retained without being cut off. Then the reinforcing core 4 is bent 180 degrees, and finally the optical cable is cut off. The final length of the optical cable 4 is about 30 cm.
[0027] The traction head 3 is made of cotton cloth 6 wrapped with high-density sponge 5, which has no specific shape and can be a pointed arch or a sphere. It should be noted that the volume of the high-density sponge 5 cannot be too small or too large. If it is too small, the traction head cannot fit closely with the inner wall of the silicon core tube, and if it is too large, the traction head cannot enter the silicon core tube. The cotton cloth 6 has no specific shape and can be a square piece of cloth or a cylindrical shape, with a length of about 20 cm. The specific structure is: the cotton cloth 6 is rolled into a cylindrical shape that can accommodate the high-density sponge 5, and one end of the cylindrical cotton cloth 6 is folded two or three times to increase firmness and facilitate winding of tape. At a distance of about 5 cm from the end, the cotton cloth 6 is pierced with a reinforcing core 11 to seal the end of the cotton cloth 6, and the end of the cotton cloth 6 and the outer side of the reinforcing core 11 and the optical cable 4 are tightly wrapped with electrical tape layer by layer to form a connecting area 2, so that the traction head 3 and the trial section 1 are firmly connected to prevent them from falling off during the trial, and then the high-density sponge 5 is filled in the cotton cloth 6, and the other end of the cotton cloth 6 is tightly wrapped with electrical tape layer by layer. Finally, the electrical tape is wrapped around the middle position where the high-density sponge 5 is wrapped to prevent the sponge from falling off, and there is no need to wrap it too tightly.
[0028] Since the trial pass device may be stuck in the middle of the pipeline due to the obstruction of the silicon core tube 10, when the pipeline is replaced and the cable blowing construction is continued, in order to save the construction time after starting the air compressor and improve the construction efficiency, multiple trial pass devices can be made in advance as backup.
[0029] like Figure 3 As shown in the schematic diagram of the trial operation site, before the optical cable 9 to be blown is placed in the silicon core tube 10, a trial device is first placed in the silicon core tube 10. Note that the traction head 3 enters the silicon core tube 10 first. After the trial section 1 completely enters the silicon core tube 10, the optical cable 9 to be laid that passes through the cable blowing machine 8 is inserted into the silicon core tube 10, and then the working module of the cable blowing machine 8 is tightened to prepare for the start of cable blowing. At the other end of the silicon core tube 10, a construction worker 7 is arranged in advance to monitor the pipe hole outlet. It should be noted that the construction worker 7 cannot look at the pipe hole at the other end to avoid injury. When starting the air compressor of the cable blowing machine, first control the optical cable 9 to be blown, and the high-pressure airflow will first push the trial device forward quickly. When the trial device rushes out of the other end of the silicon core tube 10, start the cable blowing machine 8 again, release the optical cable 9 to be laid, and start the cable blowing work. If the test device cannot reach the other end of the silicon core tube 10, it means that there is an obstruction in the silicon core tube 10. You can replace it with another silicon core tube 10 to continue the cable blowing operation and repeat the previous steps, adhering to the principle of testing first and then blowing the cable.
[0030] The device can detect whether the silicon core tube is unobstructed in a very short time, and can also remove foreign matter in the tube, facilitate the application of cable grease, and reduce the friction resistance of the optical cable in the silicon core tube.
[0031] The front end of the trial pass device of the present invention is a traction head filled with high-density sponge. Since the traction head is tightly fitted to the inner wall of the silicon core tube, it brings good airtightness. Therefore, the traction head can drive the device to move forward after being subjected to the pressure of the airflow in the silicon core tube. The whole device has a certain degree of softness and is easy to pass through the pipeline without damaging the pipeline. The traction head can remove foreign matter from the silicon core tube, which is beneficial to the application of cable blowing grease and reduce friction, avoiding foreign matter from affecting the blowing of the optical cable. The trial pass section of the device is a section of optical cable. This section of optical cable can test the passability of the silicon core tube pipeline and judge whether the optical cable can pass smoothly.
[0032] The above is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment. There may be minor local structural changes during implementation. If various changes or modifications to the present invention do not deviate from the spirit and scope of the present invention and fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
