Description

[0001] Apparatus and method for inserting a heating cable into a heating pipe [0002]

The present invention relates to an apparatus and a method for injecting a heating cable into a heating pipe.

Generally, household heating uses heating pipes installed on the floor and warm water is circulated to the inside of heating pipes to warm the floor.

The heating piping typically uses a ductile metal tube wrapped in multiple circuit rounds at the manufacturing plant. Such a metal tube can be bent into a curved line, which is advantageous in that it can be easily arranged in a desired direction.

In recent years, a heating method has been widely used in which a heating cable is inserted into a heating pipe and electricity is supplied to the heating cable to warm the water inside the heating pipe. Therefore, the manufacturer of such a heating pipe must perform an inlet operation in which a heating cable is inserted into a metal pipe wound in a round shape in a post-process.

Conventionally, in order to insert a heating cable into a heating pipe, at least two operators work to unfold the heating pipe long and long. Next, work is performed to draw the wire into the inside of the heating pipe. Next, after connecting the rear end of the drawn wire to the tip of the heating cable, pull the wire to pull the heating cable completely into the heating pipe. At this time, the pulling distance of the wire corresponds to the entire length of the heating pipe.

As described above, conventionally, in order to insert a heating cable into a heating pipe, there is a disadvantage that a considerably long working space is required to die in a circular shape.

In addition, in order to insert a heating cable into a heating pipe, at least two workers are required, resulting in an increase in labor costs, and there is a problem in that productivity is deteriorated because it depends on manual operation.

1 is a view showing an apparatus for injecting a heating cable into a heating pipe according to an embodiment of the present invention. FIG. 2 is a view showing in detail the main configuration in FIG.

A device for injecting a heating cable into a heating pipe of the present invention (hereinafter referred to as a heating cable injecting device) is a device in which a heating cable connected to a wire is drawn by pulling a wire into a heating pipe in a state in which a heating pipe is long- To improve the operation of the apparatus.

In the present invention, the heating cable (20) is injected together with water into the heating pipe (10) by using water pressure. The heating cable injection device of the present invention includes a water tank 110, a heating cable winding part 120, a heating cable input port 125, a water tank supporting part 145, a connection pipe 150, a suction motor 160, A control unit 170, and the like.

Water is stored in the water tank 110. This water allows the heating cable 20 to be injected into the heating pipe 10 by water pressure. The water tank 110 may be provided with a water level sensor 112 and a water supply unit 115. The water level sensor 112 senses the water level in the water tank 110 so that the water supply unit 115 connected to the water level sensor 112 can further supply water into the water tank 110 when the water level falls below a predetermined level have.

The heating cable winding portion is disposed adjacent to the water tank (110). The heating cable 20 is wound around the heating cable winding part 120 so as to be easily loosened. The heating cable winding portion 120 is rotated while the heating cable 20 is injected into the heating pipe 10 in the same manner as the bobbin for example so that the heating cable 20 is released from the heating cable winding portion 120 . At this time, the motor is connected to the heating cable winding part 120 so that the heating cable winding part 120 can be rotated at a constant speed.

The heating cable inlet 125 is installed inside the water tank 110 and is in fluid communication with the heating pipe 10. The heating cable inlet 125 allows the water in the water tank 110 to be injected into the heating pipe 10 so that the heating cable 20 can be injected together when the water is injected.

A connector 121 may be disposed between the heating pipe 10 and the heating cable inlet 125. For example, the connection port 121 is provided on the outer wall and the inner wall of the water tank 110, the front end of the heating pipe 10 is connected to the connection port 121 of the outer wall of the water tank 110, A heating cable inlet 125 is connected to the connection port 121 of the inner wall to be in fluid communication with each other.

The water tank support portion 145 has a receiving space and supports the water tank 110 at the bottom.

The connection pipe 150 is installed in a receiving space inside the water tank support 145 and is in fluid communication with the heating pipe 10. A connection pipe 141 may be disposed between the heating pipe 10 and the connection pipe 150. For example, the connection pipe 141 is provided on the outer wall and the inner wall of the water tank support 145, the rear end of the heating pipe 10 is connected to the connection pipe 141 of the outer wall of the water tank support 145, The connection pipe 150 may be connected to the connection hole 121 of the inner wall of the body 145 to be in fluid communication with each other.

The suction motor 160 sucks the inside of the connection pipe 150 to form a negative pressure inside the connection pipe 150 and the heating pipe 10. The suction motor 160 provides power to allow water in the water tank 110 to flow into the heating cable inlet 125 and to flow through the heating pipe 10.

The control unit 170 controls the operation of the parts, such as adjusting the speed of the suction motor 160.

In the heating cable injector of the present invention having such a configuration, the front end of the heating pipe 10 is connected to the heating cable inlet 125, the rear end of the heating pipe 10 is connected to the connection pipe 150, The heating cable 20 can be injected into the heating pipe 10 by the water pressure when the water in the water tank 110 is sucked through the heating cable input port 125 by the suction force of the heating cable 160. At this time, the heating cable 20 is injected into the heating pipe 10 while being unwound from the heating cable winding part 120.

As described above, in the present invention, the heating cable 20 is wound round in order to inject the heating cable 20 into the heating pipe 10, so that the work can be performed using the machine. Accordingly, in the present invention, it is possible to omit the work of straightening the circular heating pipe for inserting the heating cable into the heating pipe, and it is not necessary to have a considerably long working space for spreading the heating pipe, It is possible to improve the problem that the labor cost is increased and the productivity is decreased due to manual work by the operator.

On the other hand, the heating cable 20 needs only to pass through the rear end of the heating pipe 10, and does not need to be continuously injected along the connecting pipe 150. The connecting piping 150 may have one or more bent portions 150a and 150b to make it difficult for the heating cable 20 to advance further at the bent portions 150a and 150b.

The end of the connection pipe 150 may extend into the water tank 110 through the bottom of the water tank support 145 and the water tank 110. [ Accordingly, the water that has been drawn by the suction motor 160 and passed through the heating pipe 10 can be introduced into the water tank 110 again through the connection pipe 150.

When the heating cable 20 passes through the rear end of the heating pipe 10, the suction motor 160 is preferably stopped. For this purpose, a heating cable detection sensor 140 may be installed between the heating pipe 10 and the connection pipe 150. The heating cable detection sensor 140 senses that the heating cable 20 is injected into the heating pipe 10 and escapes from the rear end of the heating pipe 10.

When the heating cable 20 is detected by the heating cable detection sensor 140, the control unit 170 controls the operation of the suction motor 160 to be stopped. Accordingly, it is possible to prevent the suction motor 160 from being continuously operated even after the heating cable 20 has passed the rear end of the heating pipe 10.

In order for the heating cable 20 to be continuously injected into the heating pipe 10, the water in the water tank 110 is injected into the heating pipe 10 at a proper flow rate (flow rate) by the suction force of the suction motor 160 do. The appropriate flow rate can be set in advance within a predetermined range by the length and diameter of the heating pipe 10. A case where water is not injected into the heating pipe 10 at a proper flow rate, a case where water is leaked from the heating pipe 10, and a case where water does not flow smoothly inside the heating pipe 10 can be considered .

In the present invention, the flow meter 130 is installed in the heating cable inlet 125 to measure the flow rate of water flowing into the heating cable inlet 125. When the flow rate measured by the flow meter 130 is out of the predetermined range, the control unit 170 determines that the flow rate is abnormal and can stop the operation of the suction motor 160. Accordingly, it is possible to prevent the suction motor 160 from being continuously operated in a situation where the heating cable 20 is not injected into the heating pipe 10.

In addition, the operation sensor 135 may be installed at the heating cable inlet 125 to detect a situation where the heating cable 20 is not substantially injected into the heating pipe 10. The operation sensor 135 senses the movement of the heating cable 20 injected into the heating cable inlet 125 during operation of the suction motor 160. If the movement of the heating cable 20 is not detected by the motion sensor 135, the control unit 170 determines that the motion of the heating cable 20 is abnormal and stops the operation of the suction motor 160.

Further, in order for the heating cable 20 to be injected into the heating pipe 10 together with water, a proper flow rate of water to be injected into the heating pipe 10 is required in accordance with the rotation speed of the suction motor 160. The flow rate of the water injected into the heating pipe 10 depends mainly on the rotation speed of the suction motor 160. However, even if the rotation speed of the suction motor 160 is the same, the flow rate of water injected into the heating pipe 10 varies depending on the length and diameter of the heating pipe 10 do.

In the present invention, an input unit 180 may be provided for the operator to input the length and diameter of the heating pipe 10. The input unit 180 may be attached to the outer wall of the water tank 110, for example. When the operator inputs the length and the diameter of the heating pipe 10 to the input unit 180, the controller 170 can adjust the speed of the suction motor 160 according to the length and diameter of the heating pipe 10. Accordingly, even when the length and diameter of the heating pipe 10 are different, the control unit 170 can appropriately control the speed of the suction motor 160. [

In the method for injecting the heating cable 20 into the heating pipe 10 by the heating cable injecting apparatus of the present invention, the connecting pipe 150 is first connected to the rear end of the heating pipe 10, And the inside of the connection pipe 150 is sucked by the motor 160 to form a negative pressure. The water stored in the water tank 110 is sucked to the front end of the heating pipe 10 in accordance with the operation of the suction motor 160 so that the heating cable 20 is connected to the heating pipe 10, So that it can be injected into the inside.

A heating cable detection sensor 140 is installed between the heating pipe 10 and the connection pipe 150 and the heating cable detection sensor 140 detects the temperature of the heating cable 20 coming out of the rear end of the heating pipe 10, It is possible to stop the operation of the suction motor 160 and to prevent the energy from being wasted.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
