Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing technology, and in particular to a welding support device for integral connection of pipe fittings. Background Technology

[0002] In the prior art, when connecting two pipe fittings, a connecting sleeve is generally used to connect them. First, the connecting sleeve is heated to make it expand and soften. Then, one end of the pipe fitting is inserted into the connecting sleeve. After the connecting sleeve cools down, a sealed connection between the pipe fitting and the connecting sleeve is achieved. Then, the other end of the connecting sleeve is connected to another pipe fitting in the same way, thus connecting the two pipe fittings together. The disadvantages are that this method of connecting pipe fittings requires preheating, making the process cumbersome. In addition, after the two pipe fittings are connected, the sleeve on the outer wall protrudes from the two pipe fittings, causing unevenness at the pipe fitting connection and affecting the appearance. Therefore, this application discloses a welding support device for integral connection of pipe fittings. Utility Model Content

[0003] The purpose of this invention is to address existing problems by providing a welding support device for integrated pipe fitting connection.

[0004] This utility model is achieved through the following technical solution:

[0005] A welding support device for integral pipe connection includes a base frame. A base rod 1 and a base rod 2 are slidably and spaced apart on one side of the base frame. End rods are symmetrically arranged at the other end of the base rod 2 and the base frame. Support rod 2 and support rod 1 are symmetrically arranged on the other side of the base rod 1 and the base frame. A conical wheel is rotatably arranged on support rod 2, and a roller is rotatably arranged on support rod 1. A crossbar is symmetrically connected to the opposite side of the top of the end rod. An outer support plate is sleeved on the crossbar. Several support members are evenly distributed and connected to the inner end of the crossbar.

[0006] As a further improvement to the above solution, both ends of the bottom rod one and the bottom rod two are symmetrically provided with sliders, which are set in the sliding groove. The sliding groove is set on the opposite side surface of the bottom frame, and the bottom rod one and the bottom rod two are slidably fitted onto the sliding rod, with the inner end of the sliding rod connected to the bottom frame.

[0007] The displacement of the slider within the groove ensures the displacement of the bottom frame of bottom rod one and bottom rod two, while the sliding rod ensures the balance of displacement of bottom rod one and bottom rod two.

[0008] As a further improvement to the above solution, the axis of the roller is aligned with the length direction of the bottom frame;

[0009] This allows the pipe fitting to rotate with the support of the rollers.

[0010] As a further improvement to the above solution, the axis of the conical wheel is aligned with the width direction of the bottom frame;

[0011] This allows the pipe fitting to move under the support of the conical wheel, facilitating its approach to another pipe fitting under the displacement of bottom rod one and bottom rod two.

[0012] As a further improvement to the above solution, the support includes a fixed rod, which is vertically connected to the outer curved surface of the crossbar. An inner rod is inserted into the outer end of the fixed rod, and the end of the inner rod away from the fixed rod is inserted into the movable rod. A ball is movably disposed at the end of the movable rod away from the inner rod. An end ring is sleeved on the ball, and the end ring is connected to the end of the movable rod. A spring is disposed between the end ring and the crossbar.

[0013] The inner support is placed on the ball of the support, and the inner support supports the interface of the two pipes. The two ends of the inner support support support the two pipes that are close to each other. It is supported by springs in three directions and elastically supported by the displacement of the movable rod on the inner rod, which makes it easy to install and remove the support.

[0014] As a further improvement to the above solution, a rod sleeve is provided on the end face of the outer support plate away from the support member, and a bolt is provided vertically and threadedly on the rod sleeve;

[0015] The bolt locking rod is fitted onto the crossbar to limit and lock the outer support plate onto the crossbar. The outer support plate, together with the support rod, supports the pipe fittings, so as to achieve concentric docking of the two pipe fittings to be connected, and also to align the inner support plate.

[0016] An outer support plate is placed on the sphere of the support member, and the outer support plate supports the interface of the two pipe fittings. The two ends of the outer support plate support the ends of the two pipe fittings that are close to each other, while the ends of the two pipe fittings that are far apart are supported by the outer support plate.

[0017] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. One pipe is supported by an outer support plate and support member on a fixed crossbar, and another pipe is supported by an outer support plate and support member on a movable crossbar. The displacement of bottom rod one and bottom rod two causes the other pipe to move under the support of the support member and outer support plate, and connect with the first pipe. This facilitates welding the two pipes together. The other two pipes are supported at the bottom of rollers and cone wheels respectively, ensuring concentric support of the two crossbars and ensuring symmetrical connection of the two pipes without misalignment.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, a welding support device for integral connection of pipe fittings includes a base frame 1. A base rod 7 and a base rod 8 are slidably and spaced apart on one side of the base frame 1. An end rod 2 is symmetrically arranged on the other end of the base rod 8 and the base frame 1. A support rod 12 and a support rod 5 are symmetrically arranged on the other side of the base rod 7 and the base frame 1. A conical wheel 13 is rotatably arranged on the support rod 12, and a roller 6 is rotatably arranged on the support rod 5. A crossbar 3 is symmetrically connected to the opposite side of the top of the end rod 2. An outer support plate 4 is sleeved on the crossbar 3. Several support members 14 are evenly distributed and connected to the inner end of the crossbar 3.

[0024] As a further improvement to the above solution, both ends of the bottom rod 7 and the bottom rod 8 are symmetrically provided with sliders 9, which are located in the sliding groove 10. The sliding groove 10 is located on the opposite side surface of the bottom frame 1, and the bottom rod 7 and the bottom rod 8 are slidably fitted onto the sliding rod 11. The inner end of the sliding rod 11 is connected to the bottom frame 1.

[0025] The displacement of the slider 9 within the slide groove 10 ensures the displacement of the bottom frame 1 of the bottom rod 7 and the bottom rod 8, while the sliding rod 11 ensures the balance of the displacement of the bottom rod 7 and the bottom rod 8.

[0026] As a further improvement to the above solution, the axis of the roller 6 is aligned with the length direction of the bottom frame 1;

[0027] This allows the pipe fitting to rotate under the support of roller 6.

[0028] As a further improvement to the above solution, the axis of the conical wheel 13 is aligned with the width direction of the bottom frame 1;

[0029] This facilitates the displacement of the pipe fitting under the support of the cone wheel 13, so as to facilitate its approach to another pipe fitting under the displacement of the bottom rod 7 and the bottom rod 8.

[0030] As a further improvement to the above solution, the support member 14 includes a fixed rod 17, which is vertically connected to the outer curved surface of the crossbar 3. An inner rod 18 is inserted into the outer end of the fixed rod 17. The end of the inner rod 18 away from the fixed rod 17 is inserted into the movable rod 19. A ball 20 is movably disposed at the end of the movable rod 19 away from the inner rod 18. An end ring 21 is sleeved on the ball 20. The end ring 21 is connected to the end of the movable rod 19. A spring 22 is disposed between the end ring 21 and the crossbar 3.

[0031] The inner support strip 15 is placed on the ball 20 of the support member 14, and the inner support strip 15 supports the interface of the two pipes. The two ends of the inner support strip 15 support the two pipes that are close to each other, and are supported by springs 22 in three directions. The movable rod 19 on the inner rod 18 provides elastic support by displacement, which makes it easy to install and remove the support member 14.

[0032] As a further improvement to the above solution, a rod sleeve 41 is provided on one end face of the outer support plate 4 away from the support member 14, and a bolt 42 is provided vertically and threadedly on the rod sleeve 41.

[0033] The bolt 42 is used to lock the sleeve 41 onto the crossbar 3, thereby limiting and locking the outer support plate 4 onto the crossbar 3. The outer support plate 4, together with the support rod, supports the pipe fittings, so as to achieve concentric docking of the two pipe fittings to be connected, and also has the function of aligning the inner support plate.

[0034] The working principle of a welding support device for integral connection of pipe fittings: the end of the inner support strip 15 is placed on the ball 20 of the support member 14, and the inner support strip 15 supports the interface of the two pipe fittings. The two ends of the inner support strip 15 support the close end of the two pipe fittings 16 respectively, while the far end of the two pipe fittings is supported by the inner support strip 15.

[0035] One pipe is supported by the inner support plate 15 and support member 14 on the fixed crossbar 3, and another pipe is supported by the outer support plate 4 and support member 14 on the movable crossbar 3. The displacement of the bottom rod 1 7 and bottom rod 2 8 causes the other pipe to move under the support of the support member 14 and the outer support plate 4, and to connect and merge with the first pipe. This facilitates welding the two pipes together. The other two pipes are supported at the bottom of the roller 6 and the cone wheel 13 respectively, ensuring the concentric support of the two crossbars 3 and ensuring that the two pipes merge symmetrically without misalignment.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
