Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connection device for thermal energy and power engineering. Background Art

[0002] Hot melt connection refers to a connection method between non-metal and non-metal after heating to the (liquid) melting point. The corresponding end faces of the two pipes perpendicular to the pipe axis are brought into contact with the heating plate to heat and melt them. After removing the heating plate, the relative movement of the hot melt ends of the two pipes is adjusted to quickly press the molten ends and maintain the pressure until the joint cools down, thereby connecting the pipes.

[0003] In the traditional connection method, during the adjustment of the relative movement of two pipes, a mounting seat is usually placed at the bottom of the pipe, the mounting seat is placed on the ground, and a clamping device for the pipe and an adjustment device for the relative movement of the clamping device are arranged on the top surface of the mounting seat.

[0004] In the above operation, since the mounting seat is located at the bottom of the pipe, after the two pipes are connected, when the mounting seat needs to be taken out, the pipe needs to be moved upward for adjustment, and the mounting seat cannot be taken out conveniently and quickly, which reduces the use efficiency of the device. Utility Model Content

[0008] Grooves are symmetrically provided below the two ends of the outer wall of the arc-shaped seat along the height direction thereof, a clamping plate is hinged at the lower part of the groove, and electric push rods are hinged between the two ends of the fixed seat and the corresponding clamping plates.

[0009] Furthermore, avoidance grooves are respectively provided on the outer side surface of each of the arc-shaped seats at positions corresponding to the electric push rods.

[0010] Furthermore, guide rods are fixedly provided on the two connecting seats corresponding to the two sides of the bidirectional screw rod, and guide holes matched with the guide rods are respectively opened on the two sides of the sliding seat.

[0011] Furthermore, a turntable is provided at the end of the bidirectional screw rod extending into any one of the connecting seats, and a crank is also provided on the outer side surface of the turntable.

[0012] Furthermore, support plates are fixedly provided on the bottom surfaces of the four support rods respectively.

[0013] The advantages of the utility model compared with the existing technology are:

[0014] 1. Through the action of the provided mounting seat and the retractable support rod and the cooperation of the bidirectional screw rod, the sliding seat and the clamping device, the pipes can be clamped and relatively moved above the two pipes, thereby avoiding the trouble of taking out the mounting seat when it is located below the pipes, and improving the use efficiency of the device;

[0015] 2.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] like Figures 1 to 3 As shown, a pipeline connection device for thermal energy and power engineering includes a mounting seat 1, and retractable support rods 2 are fixedly provided at the four corners of the bottom surface of the mounting seat 1. The retractable structure of the support rod 2 is a prior art, which can be implemented by a bolt and an internal thread matching method or a positioning pin and a pin hole matching method, and connecting seats 3 are fixedly provided at both ends of the bottom surface of the mounting seat 1, and two bidirectional screw rods 4 are provided on the two connecting seats 3 to rotate together, and sliding seats 5 that are slidably matched with the mounting seat 1 are respectively threadedly connected at both ends of the bidirectional screw rod 4, and clamping devices that can position the pipeline are respectively fixed on the bottom surfaces of the two sliding seats 5;

[0023] Through the above structure, under the action of the two clamping devices, the two pipes are clamped, and then the bidirectional screw rod 4 is rotated to drive the sliding seats 5 at both ends to move relative to each other, so that the two clamped pipes can be adjusted to move relative to each other, so that an effective connection can be made at the upper position of the pipe, avoiding the trouble of removing the mounting seat when it is below the pipe.

[0024] like Figure 3 As shown, guide rods 12 are fixedly provided on the two connecting seats 3 corresponding to the two sides of the bidirectional screw rod 4, and guide holes 13 matched with the guide rods 12 are opened on both sides of the sliding seat 5. With the cooperation of the guide rods 12 and the guide holes 13, the stability of the sliding seat 5 during the left and right movement can be guaranteed.

[0025] like Figure 1 As shown, the end of the bidirectional screw rod 4 extending into any one of the connecting seats 3 is respectively provided with a turntable 14, and a crank 15 is also provided on the outer surface of the turntable 14. Under the action of the crank 15, the bidirectional screw rod 4 is driven to rotate and adjust.

[0026] like Figure 1 As shown, support plates 16 are fixedly disposed on the bottom surfaces of the four support rods 2 respectively. The arrangement of the support plates 16 can ensure the stability of the mounting base 1 during use.

[0027] Embodiment 2

[0028] Based on the first embodiment, Figure 3 As shown, the specific structure of the clamping device is as follows:

[0029] The clamping device comprises a fixed seat 6, an arc seat 7 and a clamping plate 9. The fixed seats 6 are fixedly provided on the bottom surfaces of the two sliding seats 5, and the arc seat 7 is fixedly provided on the bottom surface of the fixed seat 6.

[0030] A groove body 8 is symmetrically opened along the height direction below the two ends of the outer wall of the arc seat 7, and a clamping plate 9 is hinged at the lower part of the groove body 8. Electric push rods 10 are hinged between the two ends of the fixed seat 6 and the corresponding clamping plates 9, and the two electric push rods 10 on the same arc seat 7 are synchronously arranged.

[0031] Through the above structure, the extension and retraction of the electric push rod 10 can be controlled to drive the clamping plates 9 at both ends to swing and adjust, thereby effectively clamping the pipeline.

[0032] An avoidance groove 11 is also provided on the outer side surface of each arc-shaped seat 7 at a position corresponding to the electric push rod 10 . The avoidance groove 11 can avoid interference between the electric push rod 10 and the outer wall of the arc-shaped seat 7 during the extension and retraction process.

[0033] In specific use, first place the mounting base 1 on the two pipes to be connected, and at the same time make the clamping device correspond to the pipes, first control the extension of the electric push rod 10, which can drive the hinged clamping plates 9 at both ends to swing and adjust, so as to effectively clamp the pipes, and then use the external hot-melt mechanism to perform hot-melt operation on the ends of the pipes. After the hot-melt is completed, turn the crank 15 to drive the bidirectional screw rod 4 to rotate, and under the action of the opposite threads at both ends, drive the pipes at both ends to move relatively and adjust, so that the pipes can be effectively connected, avoiding the trouble of taking out the mounting base when it is under the pipe, thereby improving the practicality of the device.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
