Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipe foaming, in particular to a thermal insulation pipe foaming device. Background Art

[0002] Insulation pipe is the abbreviation of insulated pipe. Insulation pipe is used for the transportation of liquid, gas and other media. It is used for insulation engineering of pipelines in petroleum, chemical industry, aerospace, hot spring, military, central heating, central air conditioning, municipal and other fields. When the insulation pipe is produced and processed, it is necessary to inject insulation foam into the inside. The "insulation pipe foaming device" disclosed by the publication number "CN207044529U" has solved the technical disadvantage of difficulty in maintaining the concentricity of the inner pipe and the outer pipe. However, in actual use, devices with similar structures still have many defects. For example, when injecting insulation foam glue between pipes, it is necessary to pre-drill holes in the outer pipe wall. Drilling holes in the outer pipe wall will reduce its overall strength and affect the insulation of the inner pipe. At the same time, the uniformity of the foam glue injection through the hole in the outer pipe wall is poor, and gaps will appear between the pipes, thereby reducing the overall insulation quality of the insulation pipe. For this reason, we have designed an insulation pipe foaming device to solve the above problems. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a foaming device for thermal insulation pipes, which solves the problem of needing to pre-open holes in the outer pipe wall to reduce its overall strength when injecting foam glue and the problem of uneven injection of foam glue to cause gaps.

[0005] The fixing mechanism comprises a placement seat and a closed ring, a limiting groove is arranged at the central position of the top of the placement seat, a positioning plate is fixedly installed on the upper part of the back of the placement seat, a mounting sleeve is fixedly installed on one side of the front of the placement seat, and a mounting rod is fixedly installed on one side of the closed ring;

[0006] The foam injection mechanism includes an inner support ring and an electric push rod, connecting rods are fixedly installed on both sides of the inner support ring, two groups of foam ducts are fixedly installed on the upper part of the inner support ring, foam injection heads connected to the foam ducts are fixedly installed on the upper part of both sides of the front side of the inner support ring, a driving plate is fixedly installed on the back of the connecting rod, and the bottom of the driving plate is connected to the output end of the electric push rod fixedly installed inside the placement seat.

[0012] Beneficial Effects

[0013] The utility model provides a foaming device for heat preservation pipes. Compared with the prior art, it has the following beneficial effects:

[0014] The thermal insulation pipe foaming device improves the traditional method of injecting foam glue into the thermal insulation pipe. The inner support ring and the two groups of foam injection heads cooperate with each other. The inner support ring can provide limited support between the outer pipe and the inner pipe to ensure that the outer pipe and the inner pipe are in concentricity when the foam glue is injected. The foam injection head can inject the foam glue between the outer pipe and the inner pipe by internal injection, avoiding the need to open holes in the outer pipe wall to inject the foam glue. Therefore, the overall strength of the thermal insulation pipe can be avoided due to the holes in the outer pipe wall. At the same time, the two groups of foam injection heads improve the uniformity of injecting foam glue into the thermal insulation pipe, avoid the situation where gaps appear in the foam glue inside the thermal insulation pipe, and improve the efficiency and quality of injecting foam glue into the thermal insulation pipe.

[0024] Based on the arrangement of the above structure, the insulation pipe foaming device is composed of a supporting mechanism 1, a fixing mechanism 2 and a foaming mechanism 3, and the supporting mechanism 1 is used to support the device during operation. With the help of the supporting mechanism 1, the stability of the device during operation is improved. The fixing mechanism 2 can be limited and fixed during the insulation pipe processing, thereby improving the stability of the device during the insulation pipe processing. The foaming mechanism 3 can inject foam glue into the insulation pipe. Specifically, during the working process, the placement seat 201 can support and place the outer pipe and the inner pipe to be processed into the insulation pipe, the limiting groove 204 can limit the outer pipe and the inner pipe when they are placed on the top of the placement seat 201, the positioning plate 205 can limit the back of the outer pipe and the inner pipe when they are placed in the limiting groove 204, the closed ring 5 can limit the front of the outer pipe and the inner pipe in the limiting groove 204, and the front and rear stability of the device when injecting foam glue into the insulation pipe is ensured by the positioning plate 205 and the closed ring 5. The output end of the electric push rod 7 is connected to the back of the connecting rod 302 through the driving plate 701. The inner support ring 301 can be inserted into the foam tube through the contraction of the electric push rod 7, so that the inner wall of the outer tube and the outer wall of the inner tube of the foam tube can be supported, and the inner support ring 301 can ensure that the outer tube and the inner tube in the foam tube are at the same center of a circle, and the foam conduit 601 can transmit and guide the foam glue, so that the foam glue can be injected into the outer tube and the inner tube of the insulation tube through the foam injection head 6, thereby realizing the processing of the insulation tube by internal injection of foam glue. The internal injection method avoids the need to drill holes in the outer tube wall of the corrugated tube, and also avoids the situation where the overall strength of the insulation tube is reduced during use due to the drilling holes. At the same time, the two groups of foam injection heads 6 simultaneously inject foam glue into the insulation tube to improve the injection efficiency and the injection quality, avoid the situation where gaps appear when the foam glue is injected into the insulation tube, and improve the quality of the device during foaming processing of the insulation tube. The support seat 101 and the frame leg 102 can support the device during operation, thereby improving the stability of the device during use.

[0025] Furthermore, a shunt pipe 603 is fixedly installed at one end of the foam conduit 601, and a flexible pipe 602 is fixedly connected to the top of the shunt pipe 603. The flexible pipe 602 can be connected to an external foam glue injection device, and the shunt pipe 603 can shunt the foam glue, so that two groups of foam injection heads 6 can operate simultaneously.

The locking pin 505 can be inserted into the locking sleeve 502 when the closed ring 5 is closed, so that the closed ring 5 can be locked when closed, thereby improving the stability of the closed ring 5 when limiting the front of the foam tank.

[0027] Furthermore, multiple sets of limit push rods 202 are fixedly installed on both sides of the placement seat 201, and the output end of the limit push rod 202 is fixedly installed with a limit seat 203. The limit push rod 202 can lower the limit seat 203 by contraction, so that the top of the foam tube can be pressed and fixed by the lowering of the limit seat 203, thereby improving the stability of the device during the foaming process of the foam tube.

[0028] Furthermore, an operating rod 4 is fixedly installed on the other side of the front of the closed ring 5, and a gripping sleeve 401 is fixedly installed on the outer wall of the operating rod 4. The operating rod 4 facilitates the staff to operate the closed ring 5 when opening, and the gripping sleeve 401 increases the softness of the outer wall of the operating rod 4, thereby improving the comfort of the staff when operating the closed ring 5 through the operating rod 4.

[0029] Furthermore, the bottom of the legs 102 is fixedly mounted with foot plates 104, and a stabilizing rod 103 is fixedly mounted between the legs 102.
