Description

Technical Field

[0001] The present invention relates to the technical field of hot melt tool holders, and particularly relates to a pipeline welding hot melt tool holder for water conservancy projects. Background Art

[0002] A hot melt tool is a professional welding tool used for heating and melting thermoplastic pipes and molds and then connecting them. The hot melt tool plays a crucial role in the connection of pipes and fittings. The heating end of the hot melt tool is installed, and the hot melt tool is placed on a rack, and the corresponding heating die head is installed according to the required pipe specifications.

[0003] However, for the current pipeline welding hot melt tool holders, in the construction site of water conservancy projects, multiple pipelines need to be connected and used for operations such as draining water through the pipelines. When the pipelines are butted against each other, if the two pipelines cannot be restricted on the same horizontal line for clamping and fixing, the mouths of the two pipelines will be touched and shaken during welding, which easily leads to uneven welding and easy breakage at the welding joints of the mouths of the two pipelines. Summary of the Invention

[0004] In view of this, the present invention provides a pipeline welding hot melt tool holder for water conservancy projects, which, when the pipelines are butted against each other, restricts the pipelines at both ends on the same horizontal line for clamping and fixing. During the welding process of the two pipelines, after being touched, since the two ends of the two pipelines are restricted, the welding is uniform and not easily broken.

[0005] The present invention provides a pipeline welding hot melt tool holder for water conservancy projects, which specifically includes: guide plates; the two guide plates are symmetric to each other; at both ends of the bottom of the two guide plates, support columns are respectively fixedly installed, and universal wheels are installed at the lower ends of the support columns; symmetrically arranged bearing plates are slidably installed at the lower ends of the two guide plates;

[0006] Fixing grooves are respectively formed in the middle parts of the tops of the two bearing plates; grooves are respectively formed at both ends of the tops of the two bearing plates; two connection grooves are respectively formed on the side walls of the two bearing plates facing away from one end; bases are respectively fixedly installed at the fixing grooves in the middle parts of the two bearing plates; arc-shaped clamping plates A are fixedly installed at the tops of the two bases; guiding grooves parallel to each other are respectively formed at the upper ends of the two bearing plates;

[0007] C-shaped fixing beams are fixedly installed at the grooves of the two bearing plates; through rectangular holes are respectively formed at the rear ends of the two fixing beams; a through horizontal plate is installed at the rectangular holes of the two fixing beams; through connection columns are respectively installed in the middle parts of the tops of the two fixing beams, and pull rings are fixedly installed at the tops of the connection columns;

[0008] An adjustment block is slidably installed in the middle of the horizontal plate, and limiting plates are fixedly installed on the front and rear side walls of the adjustment block, and a handle is fixedly installed on the side wall of the rear end limiting plate. Two penetrating connecting screws are rotatably installed in the middle of the adjustment block, and a clamping seat is fixedly connected to the side wall of the limiting plate at the front end, and a handle slot is opened on the front side wall of the upper end of the clamping seat, and mutually symmetrical clamping plates are fixedly installed on the clamping seat.

[0009] Optionally, longitudinal beams are fixedly mounted at both ends of the two guide plates, and two penetrating circular holes are respectively provided at both ends of the longitudinal beams.

[0010] Optionally, guide strips are fixedly mounted on the bottoms of the two guide plates, and penetrating push rods are respectively mounted on the circular holes of the two longitudinal beams, and springs are sleeved on the push rods.

[0011] Optionally, two penetrating guide holes are respectively opened at the top ends of the two fixing beams, and penetrating column holes are respectively opened at the middle parts of the top ends of the two fixing beams.

[0012] Optionally, sliding blocks are fixedly mounted on the inner side walls of the two column holes, and the sliding blocks in the column holes are symmetrical to each other.

[0014] Optionally, mutually symmetrical sliding grooves are respectively opened on the annular side walls of the two connecting columns, and the lower ends of the annular side walls of the connecting columns are respectively covered with strong springs, and the bottoms of the two connecting columns are fixedly installed with arc-shaped splints B, and the upper ends of the two splints B are fixedly installed with mutually symmetrical protrusions, the top ends of the protrusions are fixedly installed with vertically upward guide rods, and the top ends of the guide rods are fixedly installed with stop heads.

[0015] Beneficial Effects

[0016] When two pipes in a water conservancy project according to the embodiments of the present invention are welded together, the two pipes are restricted to be on the same horizontal line and clamped and fixed. When the butt joints of the two pipes are processed and welded, the pipes are touched during processing but will not shake, and the pipes can be automatically butted after being processed by a hot melter.

[0017] In addition, arc-shaped clamps A are fixedly installed on the top of the two bases. When the two pipes are ready to be welded together, the two pipes need to be placed flat on the two clamps A respectively, and then the two clamps B are moved downward, and the pipes are clamped and fixed by connecting the clamps B and A to prevent the two pipes from being shaken by the collision of the hot melter or other objects, so that the mouths of the two pipes cannot be aligned in parallel.

[0018] In addition, it is slidably installed on the guide bar through the guide groove on the bearing plate, and the two bearing plates are grabbed and slid back to back on the guide bar. At this time, the spring on the push rod will shrink, thereby adjusting the position of the two bearing plates, and at the same time, the position of the clamping plate A is also adjusted. At this time, the pipes on the two clamping plates A will also slide along. When the mouths of the two pipes need to be processed and connected before the two bearing plates are released, the spring on the push rod will eject the bearing plates, and push the bearing plates at both ends toward each other, so that the mouths of the two pipes can be processed and connected on the same horizontal line.

[0019] In addition, an arc-shaped clamp B is fixedly installed at the bottom of the two connecting columns, and the concave surface of the clamp B is tightly attached to the upper end of the pipe. At the same time, the clamp B and the clamp A are connected to clamp the pipe. At this time, the two pipes will be on the same horizontal line, so they will not shake when touched. After the two pipe mouths are flatly connected, the welding is even and easy to connect together.

[0020] In addition, by respectively putting the melting tube die heads at both ends of the hot melt machine on the heads of the opposite ends of the two pipes, when the mouths of the opposite ends of the two pipes are hot-melted, grab the two fixed beams and pull them backwards, remove the hot melt machine and loosen the two fixed beams. At this time, the two fixed beams will automatically slide toward each other, and the two pipes will be docked and fixedly connected together, without the need for manual work to fix the two pipes together.

[0036] In order to make the purpose, scheme and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0037] Example: Please refer to Figures 1 to 10 :

[0038] The present invention proposes a pipe welding hot melter frame for water conservancy projects, comprising: a guide plate 1; two guide plates 1 are symmetrical to each other; support columns are fixedly installed at both ends of the bottom of the two guide plates 1, and universal wheels are installed at the lower ends of the support columns; the universal wheels are installed to facilitate the movement of the entire frame, and mutually symmetrical bearing plates 2 are slidably installed at the lower ends of the two guide plates 1; fixed grooves are respectively opened in the middle of the top ends of the two bearing plates 2; grooves are respectively opened at both ends of the top ends of the two bearing plates 2; two connecting grooves are respectively opened on the side walls of the two bearing plates 2 facing away from one end; bases 201 are respectively fixedly installed at the fixed grooves in the middle of the two bearing plates 2; arc-shaped clamping plates A202 are fixedly installed at the top ends of the two bases 201;

[0039] When preparing to weld two pipes together, the two pipes need to be placed flat on two clamping plates A202 respectively. Then, move the two clamping plates B502 downward, and use the clamping plate B502 to dock with the clamping plate A202 to clamp and fix the pipes, preventing the two pipes from shaking due to the collision of a hot melt machine or other objects, so that the mouths of the two pipes cannot be docked. Parallel guiding grooves 203 are respectively formed at the upper ends of the two bearing plates 2; a U-shaped fixing beam 3 is fixedly installed at the groove of the two bearing plates 2; the two fixing beams 3 are symmetrical to each other, and through rectangular holes are respectively formed at the rear ends of the two fixing beams 3; a through cross plate 4 is installed at the rectangular holes of the two fixing beams 3; connecting columns 5 are respectively installed in the middle of the tops of the two fixing beams 3, and a pull ring is fixedly installed at the top of the connecting column 5; a powerful spring is sleeved on the annular side wall of the connecting column 5, and an adjusting block 6 is slidably installed in the middle of the cross plate 4.

[0040] In addition, according to an embodiment of the present invention, as Figure 2 and Figure 4 shown in, longitudinal beams 101 are respectively fixedly installed at both ends of the two guiding plates 1, and two through round holes are respectively formed at both ends of the longitudinal beam 101. Guiding strips 102 are respectively fixedly installed at the bottoms of the two guiding plates 1, and the guiding grooves 203 on the bearing plate 2 are slidably installed on the guiding strips 102. Hold the two bearing plates 2 and slide away from each other on the guiding strips 102. At this time, the spring on the push rod 103 will contract, thereby adjusting the positions of the two bearing plates 2, and at the same time, the positions of the clamping plates A202 are also adjusted. At this time, the pipes on the two clamping plates A202 will also slide accordingly. Before the mouths of the two pipes need to be processed and docked, when the two bearing plates 2 are released, the spring on the push rod 103 will eject the bearing plates 2, push the bearing plates 2 at both ends towards each other, and let the mouths of the two pipes be processed and docked. Through push rods 103 are respectively installed at the round holes of the two longitudinal beams 101, and a spring is sleeved on the push rod 103.

[0041] In addition, according to an embodiment of the present invention, as Figure 8 and Fig. 9 shown in, two through guiding holes 301 are respectively formed at the tops of the two fixing beams 3, and through column holes 302 are respectively formed in the middle of the tops of the two fixing beams 3. Sliders 303 are fixedly installed on the inner side walls of the two column holes 302, and the sliders 303 in the column holes 302 are symmetrical to each other. The sliders 303 are slidably installed in the sliding grooves 501. L-shaped cantilevers 401 are respectively fixedly installed at both ends of the front side wall of the cross plate 4. The lower ends of the two cantilevers 401 are fixedly connected to the rear guiding plate 1. The two cantilevers 401 fixedly support the cross plate 4 to prevent the hot melt machine from tipping over when placed on the cross plate 4 and subjected to force. An adjusting hole 402 is formed through the middle of the cross plate 4.

[0042] In addition, according to an embodiment of the present invention, Figure 3 and Figure 5 As shown in the figure, the annular side walls of the two connecting columns 5 are respectively provided with symmetrical sliding grooves 501, and the lower ends of the annular side walls of the connecting columns 5 are respectively covered with strong springs. The bottoms of the two connecting columns 5 are fixedly installed with arc-shaped clamping plates B502. Grab the pull ring on the connecting column 5 and pull it upward to let the strong spring on the connecting column 5 contract to lift the clamping plate B502 upward, and then place the pipe flat on the inner concave surface of the clamping plate A202. After loosening the pull ring, the clamping plate B502 will automatically slide downward, and the inner concave surface of the clamping plate B502 will be tightly attached to the pipe. At the upper end of the pipeline, the clamping plate B502 and the clamping plate A202 are butt-jointed to clamp and fix the pipeline. At this time, the two pipelines will be on the same horizontal line, so that they will not shake when touching the pipeline. After the two pipeline mouths are flatly butt-jointed, the welding is even and convenient for connecting together. The upper ends of the two clamping plates B502 are fixedly installed with symmetrical protrusions 503, and the top of the protrusion 503 is fixedly installed with a vertically upward guide rod 504, and the top of the guide rod 504 is fixedly installed with a stopper, and the guide rod 504 runs through the guide hole 301.

[0043] In addition, according to an embodiment of the present invention, Figure 6 and Figure 7 As shown in the figure, the front and rear side walls of the adjustment block 6 are fixedly installed with limiting plates 601, and the side wall of the rear end limiting plate 601 is fixedly installed with a handle. The middle part of the adjustment block 6 is rotatably installed with two penetrating connecting screws 602. Grasp the handle on the limiting plate 601 and slide it left and right. When the position of the card holder 603 is adjusted, the position of the hot melt is also adjusted. The side wall of the front end limiting plate 601 is fixedly connected with the card holder 603, and the front side wall of the upper end of the card holder 603 is provided with a handle slot. There are symmetrical clamping plates 604, and the rear end of the hot melt handle is inserted into the handle slot of the clamping seat 603, and the lower end of the hot melt is clamped between the two clamping plates 604, and the melting tube die heads at both ends of the hot melt are respectively put on the heads of the opposite ends of the two pipes. After the mouths of the opposite ends of the two pipes are hot-melted, grab the two fixed beams 3 and pull them backwards, remove the hot melt and loosen the two fixed beams 3, then the two fixed beams 3 will automatically slide towards each other, and the two pipes will be docked and fixedly connected together.

[0044] Embodiment 2:

[0045] In addition, according to an embodiment of the present invention, Figure 1 As shown in the figure, all the push rods 103 are replaced with electric cylinders, which are inserted into the grooves of the support plate 2 and connected to the support plate 2. The support plates 2 at both ends are slid left and right using the electric cylinders to complete the docking of the two pipes. The stability performance is still high, but the cost of the hot melt rack is increased.

[0046] Embodiment 3:

[0047] In addition, according to an embodiment of the present invention, Figure 3 As shown in , the connecting column 5 is replaced with a small electric cylinder, and the small electric cylinder is fixedly installed on the fixed beam 3 and passes through the column hole 302. The lower end of the small electric cylinder is fixedly connected to the clamp B502, so that the clamp B502 can move up and down. When the clamp B502 moves downward, the clamp B502 and the clamp A202 are connected to clamp the pipeline. The two pipelines are fixed to prevent shaking before processing. After replacing the electric cylinder, the stability is high, but the cost of the hot melt rack is increased.

[0048] The specific usage and function of this embodiment are as follows:

[0049] During the use of the present invention, when two pipes in a water conservancy project need to be butt-jointed and the two pipes are to be welded together, the two pipes are first placed flat on two clamping plates A202 respectively, the pull ring on the connecting column 5 is grasped and pulled upward, so that the strong spring on the connecting column 5 contracts to lift the clamping plate B502 upward, and then the pipe is placed flat on the inner concave surface of the clamping plate A202. After the pull ring is released, the clamping plate B502 will automatically slide downward, and the inner concave surface of the clamping plate B502 will be tightly attached to the upper end of the pipe. At the same time, the clamping plate B502 and the clamping plate A202 are butt-jointed to weld together. The pipes are clamped and fixed, and the two pipes are on the same horizontal line. The rear end of the hot melt handle is then inserted into the handle slot of the holder 603, and the lower end of the hot melt is clamped between the two clamping plates 604. The melting tube dies at both ends of the hot melt are respectively put on the butt heads of the two pipes. After the butt ends of the two pipes are hot-melted, grab the two fixed beams 3 and pull them backwards, remove the hot melt and loosen the two fixed beams 3. At this time, the two fixed beams 3 will automatically slide toward each other, and the two pipes will be butt-jointed and fixedly connected together.

[0050] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.
