Description

Technical Field

[0002] Flange-type electric heating pipes are usually used to heat liquids and are also called immersion heat pipes. They are mainly used in the field of industrial electric heating. Flange-type electric heating pipes are often used for heating water tanks, oil tanks, and boilers due to their high thermal efficiency and easy installation. In different application scenarios, flange-type electric heating pipes will be designed and customized into different structures. The more commonly used flange-type electric heating pipes are round flange heating pipes and square flange heating pipes. In square flange electric heating pipes, the heating pipes are arranged in a square manner and inserted into the preset holes of the square flange. See the attached figure in the manual. Figure 9 .

[0003] When assembling a square flange electric heating tube, you first need to lock the square flange, and then manually insert the heating tube onto the square flange.

In addition, the manual insertion of heating tubes has the following problems: First, the heating tubes in large square flange electric heating tubes are longer, and manual insertion cannot be accurately aligned. In addition, the insertion depth of the heating tubes at different positions will be different, affecting the appearance of the electric heating tubes and their later use, and the manual insertion efficiency of the heating tubes is low; secondly, the heating tubes are bent when stacked, so the heating tubes need to be straightened before insertion, which further reduces the insertion efficiency of the heating tubes, and the straightening effect of the heating tubes is poor.

Elastic columns 44 are symmetrically installed on the extending plate 43, and the elastic columns 44 are connected to the longitudinal section of the extending bracket 41. A retraction member 45 for controlling the elastic column 44 to be in a retracted state is also provided on the extending plate 43. The extending device 4 is used to support the heating pipe and extend the heating pipe backward so that the heating pipe is inserted into the preset hole of the square flange. Specifically, the retraction member 45 is first pulled forward to put the extending plate 43 in a retracted state, and then the U-shaped heating pipe is sleeved on the sleeve plate 42 from right to left, and its position is adjusted according to the preset spacing of the heating pipe. After the position adjustment of the heating pipe is completed, the retraction action of the retraction member 45 is released, so that the extending plate 43 squeezes the heating pipe backward under the action of the elastic column 44.

[0038] like Figure 3 and Figure 4 As shown, the side surface of the sleeve plate 42 close to the top extension plate 43 is an arc-shaped surface, and the axis of the arc-shaped surface of the sleeve plate 42 is located in the horizontal plane of the middle part of the longitudinal section of the straightening frame 51.

The upper and lower sides of the internal support nut 423 are connected to the internal support frame 421 by a hinge with an internal support rotating rod 424. By rotating the internal support stud 422, the internal support frame 421 is driven to move synchronously inward and outward, so that the two internal support frames 421 can support the upper and lower sides of the heating pipes of different models, so that the internal support frame 421 can increase the stability of the heating pipe after position adjustment.

The retracting member 45 is rotatably connected to the top extension plate 43. The retracting member 45 is provided with a straight slider, and the top extension bracket 41 is provided with a straight slot that cooperates with the straight slider. By pulling the retracting member 45 forward, the straight slider The block is separated from the I-shaped slide groove, and then the retraction member 45 is rotated so that the I-shaped slider abuts the front side of the extension bracket 41, so that the retraction member 45 is in a retracted state. When the retraction state of the retraction member 45 needs to be released, the retraction member 45 is rotated so that the I-shaped slider is opposite to the I-shaped slide groove, and the retraction member 45 moves forward under the action of the elastic column 44, so that the extension block 431 on the extension plate 43 abuts the upper and lower sides of the front end of the heating tube. The extension block 431 is used to increase its contact area with the heating tube, thereby increasing the stability of the heating tube.

[0041] like Figure 5As shown, the straightening device 5 includes an L-shaped straightening frame 51 slidably mounted on the sliding support plate 2, and the upper and lower sides of the longitudinal section of the straightening frame 51 are connected with a fitting plate 52, and the side of the fitting plate 52 away from the straightening frame 51 is provided with a T-shaped slide groove 53 along its length direction, and a sliding fitting frame 54 is evenly slidably connected in the T-shaped slide groove 53, and the sliding fitting frame 54 is provided with an arc groove for positioning the heating tube, and the sliding fitting frame 54 is locked in the T-shaped slide groove 53 by a locking piece, and an external clamping plate 55 is distributed on the side of each fitting plate 52 away from the straightening frame 51, and the end of the external clamping plate 55 close to the transverse section of the straightening frame 51 is installed on the longitudinal section of the straightening frame 51 through an elastic telescopic plate 56, and a guide rod 57 is installed on the telescopic end of the elastic telescopic plate 56, and a guide bracket 58 cooperating with the guide rod 57 is provided on the sliding support plate 2, so that the guide rod 57 moves When it moves to the guide bracket 58, the guide rod 57 drives the elastic expansion plate 56 to contract, and the straightening device 5 can straighten the heating tube to prevent the rear end of the heating tube from being incorrectly inserted and placed. First, the position of the sliding fitting frame 54 is adjusted according to the preset spacing of the heating tube, so that the sliding fitting frame 54 corresponds to the position of the heating tube one by one, and then the position of the sliding fitting frame 54 is locked by the locking piece. When the heating tube needs to be inserted and placed, the height of the fitting plate 52 is adjusted so that the sliding fitting frame 54 is attached to the inner upper and lower ends of the heating tube, and then the straightening frame 51 is pushed to move backward. When the guide rod 57 contacts the guide bracket 58, it drives the elastic expansion plate 56 to move to one side of the fitting plate 52 so that the outer clamping plate 55 clamps the outer upper and lower ends of the heating tube, and then controls the position adjustment plate 3 to move backward, so that the heating tube can be inserted into the square flange.

[0042] like Figure 5 and Figure 7 As shown, the lower side of the external clamping plate 55 is installed with an external pressure bonding plate 552 through an external pressure spring column 551, and the opposite sides of the guide rod 57 and the guide bracket 58 are provided with mutually matching inclined surfaces. The external pressure bonding plate 552 can perform external clamping for different types of heating tubes under the action of the external pressure spring column 551, and the inclined surface setting of the guide rod 57 and the guide bracket 58 can increase their degree of fit.

[0043] like Figure 6 As shown, a plug-in column 59 is provided at the end of the longitudinal section of the bonding plate 52, and a plug-in mechanism 6 for supporting the plug-in column 59 is provided on the assembly base 1. By supporting the right end of the bonding plate 52, the supporting effect of the straightening device 5 on the heating tube can be increased.

[0044] like Figure 3 and Figure 6As shown, the plug-in mechanism 6 includes a plug-in support 61 installed on the assembly base 1, and the upper end of the plug-in support 61 is a frame-type structure. A plug-in slider 62 is slidingly provided in the plug-in support 61 for the plug-in column 59 to be inserted; the upper side surface of the assembly base 1 is provided with a positioning groove 11, and the sliding support plate 2 is provided with a positioning locking block 12 inserted in the positioning groove 11. The positioning locking block 12 is installed in the sliding support plate 2 through a compression spring. When the heating tube is adjusted to the position of the extension device 4 and is extended by the extension plate 43, the sliding support plate 2 is pushed to the right so that the positioning locking block 12 is inserted into the positioning groove 11, so that the position of the sliding support plate 2 is positioned, and at this time the plug-in column 59 is inserted into the plug-in slider 62.

[0045] like Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the longitudinal section of the straightening frame 51 is a hollow structure, and a rebound telescopic column 521 is provided on the side of the longitudinal section of the straightening frame 51 corresponding to the bonding plate 52. The fixed end of the rebound telescopic column 521 is installed on the side wall of the hollow structure of the straightening frame 51, and a trapezoidal transmission body 522 is provided on the side of the telescopic end of the rebound telescopic column 521 located in the straightening frame 51. An extrusion column 523 is provided in the hollow structure of the straightening frame 51, and a pushing body 524 is provided on the extrusion column 523 for cooperating with the trapezoidal transmission body 522 and pushing the rebound telescopic column 521 to extend. One end of the extrusion column 523 is installed on the end wall of the hollow structure of the straightening frame 51 through a reset spring 525. The other end of 23 passes through the straightening frame 51 and extends into the plug-in column 59, and the plug-in column 59 is correspondingly set to a hollow structure; the side wall of the plug-in slider 62 away from the plug-in column 59 is connected to the extrusion screw 63 by threaded fitting, and the extrusion screw 63 is located in the plug-in slider 62. One end is provided with an extrusion disk 64 for pushing the extrusion column 523. When the plug-in column 59 is inserted into the plug-in slider 62, rotating the extrusion screw 63 can drive the extrusion column 523 to move to the left, and the pushing body 524 on the extrusion column 523 pushes the telescopic end of the rebound telescopic column 521 to extend, so that the sliding bonding frame 54 on the bonding plate 52 is attached to the upper and lower ends of the inner side of the heating tube.

[0046] It should be noted that in other embodiments, in order to increase the stability of the sliding support plate 2, the elastic positioning method of the positioning groove 11 and the positioning locking block 12 can be replaced with other existing rigid locking connection methods, such as bolt and nut locking, hook locking, etc.

[0047] like Figure 7 and Figure 8As shown, the locking part includes a U-shaped rod 541 arranged in the sliding fitting frame 54, and a U-shaped slide matching the U-shaped rod 541 is provided in the sliding fitting frame 54. The U-shaped rod 541 is connected to the U-shaped slide by a locking spring 542, and the lower end side wall of the T-shaped slide 53 is evenly provided with locking holes 543 along its length direction. One end of the U-shaped rod 541 located in the T-shaped slide 53 is locked in the locking hole 543. By pressing the U-shaped rod 541 inward, the U-shaped rod 541 is moved out of the locking hole 543, and then the sliding fitting frame 54 is adjusted to a suitable position, and the U-shaped rod 541 is re-locked in the corresponding locking hole 543.

[0048] The corresponding assembly steps of the flange-type electric heating tube assembly equipment are: the first step is to pull the sliding support plate 2 to the left to facilitate the placement of the heating tube sleeve on the sleeve plate 42, and adjust the position of the sliding fitting frame 54 according to the preset spacing of the heating tube so that the sliding fitting frame 54 is at a suitable spacing, and then adjust the position of the inner support frame 421 according to the model of the heating tube so that the two inner support frames 421 can support the upper and lower sides of the inside of heating tubes of different models, and then adjust the position of the position adjustment plate 3 forward and backward according to the length of the heating tube.

[0049] In the second step, pull the retracting part 45 forward so that the top extension plate 43 is in a retracted state, and then put the U-shaped heating tube on the sleeve plate 42 from right to left, and adjust its position according to the preset spacing of the heating tube. The inner support frame 421 supports the heating tube when adjusting its position, thereby increasing the stability of the heating tube after the position adjustment.

[0050] In the third step, the retracting member 45 is rotated so that the I-shaped slider is opposite to the I-shaped groove. The retracting member 45 moves forward under the action of the elastic column 44, so that the top extension block 431 on the top extension plate 43 abuts against the upper and lower sides of the front end of the heating tube.

[0051] In the fourth step, the sliding support plate 2 is pushed to the right so that the positioning locking block 12 is inserted into the positioning groove 11, so that the position of the sliding support plate 2 is positioned. At this time, the plug-in column 59 is inserted into the plug-in slider 62, and the rotation of the extrusion screw 63 can drive the extrusion column 523 to move to the left. The pushing body 524 on the extrusion column 523 pushes the telescopic end of the rebound telescopic column 521 to extend, so that the sliding bonding frame 54 on the bonding plate 52 is attached to the upper and lower ends of the inner side of the heating tube.

[0052] The fifth step is to push the straightening frame 51 to move backward. When the guide rod 57 contacts the guide bracket 58, it drives the elastic telescopic plate 56 to move to one side of the bonding plate 52, so that the external clamping plate 55 can clamp the upper and lower ends of the outer side of the heating tube. The straightening frame 51 is continued to be pushed backward to straighten the heating tube, and the sliding bonding frame 54 and the external pressure bonding plate 552 are respectively attached to the inner and outer sides of the rear end of the heating tube.

[0053] In the sixth step, the position adjustment plate 3 is controlled to move backward so that the heating tube can be inserted into the square flange, and then the end of the heating tube is locked on the square flange. Then, the retraction part 45 is pulled forward and the straightening frame 51 is pushed to the initial position. After that, the sliding support plate 2 is pulled to the left as a whole to separate the heating tube from the present invention. Finally, the square flange is controlled to move upward so that the present invention can install the next group of heating tubes.
