Description

Technical Field

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

[0002] In the field of thermal energy and power engineering, thermal energy and power engineering pipelines are connected by hot melt, which is a connection method after heating to the (liquid) melting point. The corresponding end faces of the two pipes perpendicular to the pipe axis are contacted with the heating plate to heat and melt them. After removing the heating plate, the melted ends are quickly pressed and kept until the joint cools down, thereby connecting the pipes.

[0003] At present, when hot-melting the pipelines in thermal energy and power engineering, a heating plate is generally used to hot-melt the joints of the pipelines. Although this can achieve the purpose of hot-melting, after hot-melting, the heating plate needs to be manually and quickly removed to facilitate the docking of the two pipelines. In the process of removing the heating plate, the heating plate is adhered to the end of the pipeline. Forcibly removing the heating plate will not only cause shaking and deviation at the joint of the pipeline, thereby affecting the normal docking of the pipeline and reducing the sealing of the pipeline connection; but also it is easy to be burned by the heating plate in the process of removing the heating plate.

[0046] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0047] like Figure 1 As shown, the embodiment of the utility model provides a thermal energy and power engineering pipeline connection device, including:

[0048] A base 1, wherein a strip-shaped groove is formed at the center of the base 1;

[0049] A bidirectional screw rod 2 is arranged in the strip-shaped groove and is rotatably connected to the base 1, wherein the first end and the second end of the bidirectional screw rod 2 are respectively provided with threads, and the directions of the threads at the first end and the second end of the bidirectional screw rod 2 are opposite;

[0050] A first motor 101 fixedly connected to the first end of the bidirectional screw rod 2;

[0051] Two pipe fixing devices threadedly connected to the first end and the second end of the bidirectional screw rod 2 respectively;

[0052] A heating device is arranged in the middle of the base 1 and is perpendicular to the strip-shaped groove;

[0053] The two pipeline fixing devices are symmetrically arranged with the heating device as the center.

[0054] In this embodiment, the output shaft of the first motor 101 is fixedly connected to the bidirectional screw 2, and the first motor 101 drives the bidirectional screw 2 to rotate. Since the two ends of the bidirectional screw 2 are engraved with threads in opposite directions, and the two ends of the bidirectional screw 2 are respectively threadedly connected to the pipeline fixing device, during the rotation of the bidirectional screw 2, the two pipeline fixing devices will move horizontally along the bidirectional screw 2 under the action of the force of the threads. Specifically, since the threads at both ends are in opposite directions, the two pipeline fixing devices move together toward the center of the base 1, that is, the heating device. During the operation of the thermal energy and power engineering pipeline connection equipment, pipelines are respectively fixed on the two pipeline fixing devices. When the pipeline fixing devices move a certain distance, the pipelines fixed on the device contact the heating device. When the melting point of the pipeline is reached, the port of the pipeline is melted to the target state, and the heating plate of the heating device can be removed, thereby bonding the ports of the two pipelines together. Since the heating plate of the heating device can be quickly removed by electromechanical settings, and the pipelines can be fixed by the pipeline fixing device during the hot melting and removal process, the pipelines will not shake or deviate, so the sealing of the pipeline joint is well guaranteed, and the problem of being scalded by manual operation is avoided.

[0055] like Figure 2 As shown, in an optional embodiment of the utility model, the pipeline fixing device includes:

[0056] A connecting seat 3 threadedly connected to the bidirectional screw rod 2;

[0057] A movable plate 4 fixedly connected to the connecting seat 3;

[0058] A supporting mechanism fixedly connected to the movable plate 4;

[0059] A clamping device and a placing device are fixed on the supporting mechanism.

[0060] In this embodiment, the connecting seat 3 extends vertically into the strip groove of the base 1 and is threadedly connected to the bidirectional screw 2. One end of the connecting seat 3 is fixedly connected to the movable plate 4, and a movable wheel 401 is respectively arranged at the four corners of the bottom of the movable plate 4. When the first motor 101 drives the bidirectional screw 2 to rotate, the connecting seat 3 drives the movable plate 4 to move parallely under the drive of the thread. The movable wheel 401 rotates on the base 1, so that the movement of the movable plate 4 is smoother, ensuring the stability during the hot melting process of the pipe. A supporting mechanism is mounted above the movable plate 4, and the function of the supporting mechanism is to support the clamping device and the placing device. The pipe is placed on the placing device, and the clamping device fixes the pipe.

[0069] In this embodiment, the clamping device is fixed on the cylinder 51 through a connecting piece 61. Preferably, two triangular connecting pieces 61 are inserted into the cylinder 51, and two corners of the triangle are respectively fixed with two fixed clamping jaws 6 by screws. The bottom of the fixed clamping jaw 6 is also fixedly connected to the first hydraulic cylinder 501. When the pipeline needs to be placed, the piston rods at both ends of the first hydraulic cylinder 501 contract inwards, driving the fixed clamping jaw 6 to open; after the pipeline is placed, the piston rods at both ends of the first hydraulic cylinder 501 expand outwards, driving the fixed clamping jaw 6 to close, thereby fixing the pipeline.

[0070] In an optional embodiment of the utility model, the placement device includes:

[0071] A second hydraulic cylinder 702 disposed at the end of the cylinder 51 and fixedly connected to the cylinder 51, wherein a first end of the second hydraulic cylinder 702 is fixedly connected to the cylinder 51;

[0072] A support plate 7 is fixedly connected to the second end of the second hydraulic cylinder 702 .

[0073] In this embodiment, the end of the cylinder 51 is fixedly connected to the second hydraulic cylinder 702, and the end of the second hydraulic cylinder 702 is connected to the support plate 7, and the second hard rubber plate 701 is fixed on the surface of the support plate 7. When the piston rod of the second hydraulic cylinder 702 moves, the support plate 7 can be driven to move up and down. When the pipeline needs to be hot-melt connected, the pipeline is placed on the second hard rubber plate 701, and the second hydraulic cylinder 702 is started to adjust the height of the support plate 7 according to the diameter of the pipeline, so that the pipeline is fixed at the center of the support plate 7 and the two sets of fixed jaws 6 to ensure the fixing effect of the pipeline. Pipes of different diameters can be fixed by cooperating with the support plate 7 through the two fixed jaws 6, so that the applicability of the equipment is greatly improved. The outer surface of the second hydraulic cylinder 702 is also provided with a protective cover 703, and the protective cover 703 is fixedly connected to the cylinder 51 for protecting the second hydraulic cylinder 702. The second hard rubber plate 701 increases the friction with the pipeline, so that the pipeline remains stable.

[0074] like Figure 3 As shown, in an optional embodiment of the utility model, the heating device includes:

[0075] A fixing base 8 fixedly connected to the base 1;

[0076] A detachable frame 9 bolted to the fixing seat 8;

[0077] A heating plate 10 slidably connected to the fixing seat 8 and the removable frame 9;

[0078] A first square notch is provided at one end of the fixing seat 8, a groove is provided in the first square notch, and the heating plate 10 is provided in the groove; a second square notch is provided at one end of the removable frame 9, a groove is provided in the second square notch, and the heating plate 10 is provided in the groove; the first square notch and the second square notch have the same width;

[0079] A lifting device fixedly connected to the heating plate 10.

[0080] In this embodiment, the fixed seat 8 and the removable frame 9 are fixedly connected together by at least one second fixing bolt 802, and the ends of the fixed seat 8 and the removable frame 9 are respectively provided with a first square recess and a second square recess. The other end of the removable frame 9 is provided with a through groove, and the heating plate 10 extends from the through groove into the square recess of the fixed seat 8 and the removable frame 9 under the fixation of the lifting device, and can move up and down parallel in the fixed seat 8 and the removable frame 9 under the guidance of the groove. When the pipeline needs to be hot-melted, the lifting device places the heating plate 10 in the square recess, and the pipelines carried by the two pipeline fixing devices are respectively in contact with the heating plate 10 until the port of the pipeline is melted to the target state, and then the lifting device lifts the heating plate 10 upward, and the hot-melt ports of the two pipelines are in contact and bonded.

[0081] In an optional embodiment of the utility model, the lifting device includes:

[0082] Two third hydraulic cylinders 801 are separated at both ends of the fixing base 8, and the first ends of the third hydraulic cylinders 801 are fixedly connected to the fixing base 8;

[0083] A top plate 1001 is bolted to the second end of the third hydraulic cylinder 801 , and the top plate 1001 is fixedly connected to one end of the heating plate 10 .

[0084] In this embodiment, the two third hydraulic cylinders 801 are respectively fixed to the left and right ends of the fixing seat 8, and the piston rods of the two third hydraulic cylinders 801 are fixedly connected to the top plate 1001 through the first fixing bolts 1002, and the bottom end of the top plate 1001 is fixedly connected to the heating plate 10. When the heating plate 10 needs to be hot-melted to the pipeline, the piston rods of the two third hydraulic cylinders 801 are retracted, and the heating plate 10 is located in the square frame. When the heating plate 10 needs to be removed to dock the pipeline, the piston rods of the two third hydraulic cylinders 801 are pushed out upward to lift the heating plate 10 upward to avoid burns when manually removing the heating plate 10.

[0085] After the two pipes are connected by hot-melt connection, the first fixing bolt 1002 and the second fixing bolt 802 are unscrewed, and then the fixing jaws 6 are controlled to open to release the fixation of the pipes, thereby facilitating the removal of the pipes from the equipment.

[0086] In an optional embodiment of the present invention, the inner side of the fixed clamping jaw 6 is fixedly connected to the first hard rubber plate 601 , and the end surface of the support plate 7 is fixedly connected to the second hard rubber plate 701 .

[0087] In this embodiment, the first hard rubber plate 601 and the second hard rubber plate 701 are used to increase the friction between the pipe and the pipe to keep the pipe stable. This prevents the pipe from shaking during the pipe docking process, which affects the air tightness of the pipe. The surface of the first hard rubber plate 601 is provided with multiple sets of anti-skid grooves. When the fixed clamp 6 is used to clamp and fix the outside of the pipe, the first hard rubber plate 601 is used to avoid pinching the outside of the pipe. At the same time, the multiple sets of anti-skid grooves on the surface of the first hard rubber plate 601 can ensure the fixing effect of the fixed clamp 6.

[0088] The specific application scenarios of the utility model are further described below:

[0089] When connecting the pipes, first start the second hydraulic cylinder 702 according to the diameter of the pipes, adjust the height of the support plate 7, so that the pipes are fixed at the center of the support plate 7 and the two sets of fixed jaws 6, and ensure the fixing effect of the pipes. Put the butt ends of the two pipes into the inner side of the fixed jaws 6, support the pipes through the support plate 7, start the first hydraulic cylinder 501 for the return stroke, and the two sets of fixed jaws 6 gradually gather together to clamp and fix the outer side of the pipes, so that the pipes can remain stable during the connection process. At the same time, two groups of fixed jaws 6 cooperate with the support plate 7 to fix pipes of different diameters, and then start the first motor 101 to drive the bidirectional screw 2 to rotate, and drive the movable plate 4 to move relatively under the connection of the connecting seat 3, and the movable plate 4 is stably moved by the multiple groups of movable wheels 401 at the bottom of the movable plate 4. The two groups of movable plates 4 move relatively until the joint of the two pipes is against the outside of the heating plate 10, and the joint of the two pipes is hot-melted by the heating plate 10. After the joint of the two pipes is hot-melted, the third hydraulic cylinder 801 is started to push the top plate 1001 up, so that the heating plate 10 is pulled out from the inside of the slot to avoid the situation of being burned by manually taking out the heating plate 10. The whole operation process is simple and convenient. The utility model can improve the overall sealing and applicability of the power engineering pipeline quick connection equipment through design, and can also avoid the situation of being burned by manually taking out the heating plate 10.

[0090] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
