Description

Technical Field

[0001] The present invention relates to the technical field of floor heating pipe installation, and particularly to a pipe clamping and fixing device for laying floor heating pipes. Background Art

[0002] Floor heating is short for floor radiant heating. Taking the entire ground as a radiator, through the heat medium in the floor radiant layer, the entire ground is evenly heated. Utilizing the law of the ground's own heat storage and heat radiation upward, heat is conducted from bottom to top to achieve the purpose of heating. Laying floor heating mainly uses coiled pipes and the foamed plastic board below them, and a cement surface is covered on the coiled pipes. When installing floor heating pipes, the floor heating pipes are usually arranged in a spiral shape (as Figure 7 shown) to increase the heat radiation area. While arranging the floor heating pipes, floor heating staples are used to clamp and fix the floor heating pipes to the foamed plastic board to prevent them from shaking.

[0003] For the fixation of floor heating pipes, manual pressing or using a staple gun to repeatedly press the staples at different points on the floor heating pipes is usually adopted. However, due to the large number of bends in the floor heating pipes, a large number of staples are required, while fewer staples are used in the straight positions. It is necessary to continuously adjust the position of the staple points, and the fixing process is very cumbersome, taking a long time for fixation. Moreover, the position of the staples can only be determined by visual inspection, which easily leads to waste caused by too many staples or poor fixing effect due to too few staples.

[0004] In addition, during the process of laying the floor heating pipes into a spiral shape, manual operation is usually used, which very easily leads to inconsistent distances between adjacent floor heating pipes, and some sections of the laid floor heating pipes are offset, thus unable to ensure uniform heat transfer outward from the laid floor heating pipes, reducing the heat transfer effect of the floor heating pipes. Summary of the Invention

[0005] The present invention provides a pipe clamping and fixing device for laying floor heating pipes, which solves the technical problems that the position of the staples needs to be adjusted by visual inspection, the position of the staple points needs to be continuously adjusted, the fixing efficiency is low, and the number of staples is inconvenient to adjust, resulting in poor fixing effect.

[0006] A pipe clamping and fixing device for laying floor heating pipes provided by the present invention includes a bearing plate. Both the left and right sides of the bearing plate are fixedly connected with inverted U-shaped clamps through connecting plates. Feeding members are installed above the inverted U-shaped clamps on both the left and right sides of the bearing plate. A driving member for cooperating with the feeding members to clamp the floor heating pipes is installed inside the bearing plate. The driving member includes two rollers symmetrically rotatably connected to the inside of the bearing plate through a rotating shaft, an intermittent ejection assembly arranged on the upper part of the bearing plate, and an adaptive speed change unit installed between the two rotating shafts for cooperating with the intermittent ejection assembly.

[0007] In one possible implementation, the adaptive speed change unit includes a prism fixedly connected to the end of the left rotating shaft, a prism shaft rotatably connected to the bottom of the supporting plate cavity by a convex plate and slidably connected to the inside of the prism, a fixed frame fixedly connected to the bottom of the supporting plate cavity, a rotating column rotatably connected to the front of the fixed frame, and a No. 2 spring telescopic column rotatably connected to the front of the fixed frame, the end of the prism shaft and the left end of the rotating column are connected to each other through a gear set, the rotating column and the No. 2 spring telescopic column are connected to each other through a pulley unit, the No. 1 rotating cylinder rotatably connected to the bottom of the supporting plate cavity through the No. 1 ring frame, the end of the rotating shaft located on the right is fixedly connected to the No. 1 friction block that contacts the right end of the No. 1 rotating cylinder through the No. 1 spring telescopic column, the No. 2 rotating cylinder rotatably connected to the bottom of the supporting plate cavity through the No. 2 ring frame and contacts the left end of the No. 1 rotating cylinder, and the right end of the No. 2 spring telescopic column is fixedly connected to the No. 2 friction block that contacts the left end of the No. 2 rotating cylinder.

[0008] In one possible implementation, the unloading part includes a guide rod fixedly connected to the left and right sides of the supporting plate by a fixing rod for placing staples, and the guide rod consists of a horizontal section and an inclined section fixedly connected to the rear end of the horizontal section. The front part of the horizontal section of the guide rod is slidably connected to a round rod, and a reset spring is fixedly connected between the rear end of the round rod and the inner cavity of the guide rod. The front part of the round rod is an inclined surface, and the left and right sides of the supporting plate are fixedly connected with baffles by cross rods, and the front part of the baffle is provided with a through hole for the round rod to extend into.

[0009] In one possible implementation, the intermittent ejection assembly includes a convex rod fixedly connected to the upper part of the supporting plate symmetrically on the left and right, a transverse rod hinged to the end of the convex rod through a rotating rod and a torsion spring, the right section of the transverse rod located on the left is a telescopic section, a pressure rod fixedly connected to the lower end surface of the transverse rod and located directly above the inclined surface of the round rod, a convex block fixedly connected to the outside of the No. 1 rotating drum, and a push column for cooperating with the convex block fixedly connected to the lower end surface of the transverse rod and located directly above the No. 1 rotating drum.

[0010] In one possible implementation, the supporting plate is composed of a left plate and a right plate, and a distance adjusting member is installed between the left plate and the right plate. The distance adjusting member includes a slide tube fixedly connected to the left end surface of the right plate in the supporting plate, a slide rod fixedly connected to the right end surface of the left plate in the supporting plate, and the slide rod is slidably connected to the inside of the slide tube. Positioning holes are equidistantly provided on the outside of the slide tube and the slide rod along their axial direction, and positioning pins are inserted into the positioning holes.

[0011] In a possible implementation, the left and right parts of the upper end surface of the carrier plate are both symmetrically fixedly connected with spring telescopic plates, and the lower sides of the ends of the spring telescopic plates are hinged with inverted U-shaped guide hoops through connecting columns.

[0012] In a possible implementation, rolling balls are embedded and rotatably connected to the four corners of the lower end surface of the supporting plate.

[0013] In a possible implementation, a strip-shaped groove for the staple to extend into is provided outside the inverted U-shaped clamp and directly below the inclined plane of the round rod.

[0014] As can be seen from the above technical solutions, the present invention has the following advantages:

[0015] In the present invention, when the left and right rollers move along the spiral path during laying, the rotation speeds of the two rollers remain the same when moving on the straight section of the spiral floor heating pipe. As a result, the frequency of the intermittent ejector being triggered is uniform, so the number of staples ejected is fixed. When moving on the spiral bending section, a speed difference appears between the two rollers, which further accelerates the frequency of the intermittent ejector being triggered. Therefore, the number of staples ejected for the bending section increases. By using the change in the speed difference between the inner and outer diameters of the two rollers to adjust different numbers of staples to be nailed at different positions of the spiral floor heating pipe, the installation speed is accelerated, and at the same time, the clamping effect of the staples on the floor heating pipe is enhanced.

[0016] In the present invention, when the carrier plate moves, it drives the inverted U-shaped clamp to move synchronously to straighten the floor heating pipe, and at the same time, it also ensures that the distances between adjacent sections of the floor heating pipe are equal.

The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] See also Figure 1 The present invention provides a technical solution: a pipe clamping and fixing device for laying floor heating pipes, comprising a supporting plate 1, with rolling balls embedded in the four corners of the lower end surface of the supporting plate 1 for rotation, and the rolling balls are used to increase the support points of the supporting plate 1, so that the supporting plate 1 can move smoothly during operation, and the left and right sides of the supporting plate 1 are fixedly connected to the inverted U-shaped pressure hoop 2 through the connecting plate, and blanking parts 3 are installed on the left and right sides of the supporting plate 1 and directly above the inverted U-shaped pressure hoop 2, and a driving part 4 for cooperating with the blanking part 3 to clamp the floor heating pipe is installed inside the supporting plate 1, and a spring telescopic plate 9 is fixedly connected to the upper end surface of the supporting plate 1 symmetrically in the front and rear, and the ends of the spring telescopic plate 9 are hinged to the inverted U-shaped guide hoop 10 through connecting columns.

[0029] See also Figure 2, in this embodiment, the bearing plate 1 is composed of a left plate and a right plate, and a distance adjusting member 8 is commonly installed between the left plate and the right plate.

Positioning holes 83 are equidistantly arranged along the axial direction on the outer parts of the sliding cylinder 81 and the sliding rod 82, and positioning pins 84 are inserted into the positioning holes 83.

[0030] Before use, first adjust the length of the bearing plate 1 with the distance adjusting member 8 according to the distance between two adjacent floor heating pipes to be laid. Pull out the positioning pin 84 from the positioning hole 83, and then the distance between the left plate and the right plate can be adjusted. After the adjustment is completed, insert the positioning pin 84 into the positioning hole 83 where the sliding rod 82 and the sliding cylinder 81 coincide with each other to lock it. Thus, it can be adjusted according to the laying specifications of different floor heating pipes, increasing the applicability of the device.

[0031] Please refer to Figure 6 , in this embodiment, the blanking member 3 includes guide rods 31 for placing staples fixedly connected to the left and right sides of the bearing plate 1 through fixing rods. The guide rods 31 are composed of a horizontal section and an inclined section fixedly connected to the rear end of the horizontal section. A round rod 32 is slidably connected to the front end of the horizontal section of the guide rod 31, and a return spring is commonly fixedly connected between the rear end of the round rod 32 and the inner cavity of the guide rod 31. The front part of the round rod 32 is a slope. Baffles 33 are fixedly connected to the left and right sides of the bearing plate 1 through cross bars. Through holes for the round rod 32 to extend into are opened in the front parts of the baffles 33. A strip-shaped groove for the staple to extend into is opened on the inverted U-shaped press hoop 2 and directly below the slope of the round rod 32.

[0032] Please refer to Figure 1 and Figure 4The driving member 4 includes two rollers 42 symmetrically connected to the inside of the carrier plate 1 by a rotating shaft 41, an intermittent ejection assembly 43 arranged on the upper part of the carrier plate 1, and an adaptive speed change unit 44 installed between the two rotating shafts 41 for cooperating with the intermittent ejection assembly 43. The adaptive speed change unit 44 includes a prism 441 fixedly connected to the end of the left rotating shaft 41, a prism shaft 442 rotatably connected to the bottom of the cavity of the carrier plate 1 through a convex plate, and the prism shaft 442 is slidably connected to the inside of the prism 441 and a fixed frame 5 fixedly connected to the bottom of the cavity of the carrier plate 1. The fixed frame consists of a vertical plate and two vertical blocks fixedly connected to the front end surface of the vertical plate on the left and right, a rotating column 443 rotatably connected to the vertical block on the left front side of the fixed frame 5, and a No. 2 spring telescopic column 444 rotatably connected to the vertical block on the right front side of the fixed frame 5. The end of the prism shaft 442 and the left end of the rotating column 443 are connected to each other through a gear set 445. The rotating column 443 and the No. 2 spring telescopic column The contraction column 444 is connected to each other through the pulley unit 446, and is connected to the No. 1 rotating drum 447 at the bottom of the cavity of the carrier plate 1 through the No. 1 ring frame 6. The end of the rotating shaft 41 at the right part is fixedly connected to the No. 1 friction block 449 that touches the right end of the No. 1 rotating drum 447 through the No. 1 spring telescopic column 448. The No. 2 rotating drum 4410 is connected to the bottom of the cavity of the carrier plate 1 and contacts the left end of the No. 1 rotating drum 447 through the No. 2 ring frame 7. The right end of the No. 2 spring telescopic column 444 is fixed. There is a fixed connection with a No. 2 friction block 4411 which contacts the left end of the No. 2 rotating cylinder 4410. The diameter of the No. 1 rotating cylinder 447 is larger than the diameter of the No. 2 rotating cylinder 4410. The force with which the No. 1 spring telescopic column 448 presses the No. 1 friction block 449 is greater than the force with which the No. 2 spring telescopic column 444 presses the No. 2 friction block 4411. The friction coefficient between the No. 1 friction block 449 and the No. 1 rotating cylinder 447 is greater than the friction coefficient between the No. 2 friction block 4411 and the No. 2 rotating cylinder 4410.

[0033] See also Figure 1 、 Figure 4 and Figure 6 The intermittent ejection assembly 43 includes a protruding rod 431 fixedly connected to the upper part of the supporting plate 1 symmetrically on the left and right, a transverse rod 432 hinged to the end of the protruding rod 431 through a rotating rod and a torsion spring, the right section of the transverse rod 432 located on the left is a telescopic section, a pressure rod 433 fixedly connected to the lower end surface of the transverse rod 432 and located directly above the inclined surface of the round rod 32, a protrusion 434 fixedly connected to the outside of the No. 1 rotating cylinder 447, and a top column 435 for cooperating with the protrusion 434 fixedly connected to the lower end surface of the transverse rod 432 and located directly above the No. 1 rotating cylinder 447.

[0034] The U-shaped staples are successively sleeved and arranged outside the material guiding rod 31. Under the action of the inclined section at the rear of the material guiding rod 31, the placed U-shaped staples move forward until the U-shaped staple at the forefront slides to the inclined plane position of the round rod 32. Then, the bearing plate 1 is placed between two adjacent parallel floor heating pipes, and the inverted U-shaped clamping hoop 2 is sleeved outside the floor heating pipe. At the same time, the inverted U-shaped guiding hoop 10 is also sleeved outside the floor heating pipe, so as to enhance the stability during the laying of the floor heating pipe and prevent the floor heating pipe from shifting during the laying process. Then, the bearing plate 1 is pushed to move on the foamed plastic board. The roller 42 contacts and rotates with the upper end surface of the foamed plastic board, thereby driving the rotating shaft 41 to rotate. The rotating shaft 41 on the right drives the first friction block 449 to rotate through the first spring telescopic column 448. The first friction block 449 then drives the first rotating cylinder 447 in contact with it to rotate in the same direction as the right roller 42.

[0035] The rotating shaft 41 on the left drives the prism shaft 442 to rotate through the prism barrel 441. The prism shaft 442 contacts and drives the gear set 445 to rotate. The gear set 445 reverses the rotation direction of the roller 42 and transmits it to the rotating column 443. The rotating column 443 then drives the second spring telescopic column 444 to rotate through the pulley unit 446. The second spring telescopic column 444 then drives the second rotating cylinder 4410 to rotate through the second friction block 4411. The second rotating cylinder 4410 and the first rotating cylinder 447 rotate in opposite directions. Since the friction coefficient between the first friction block 449 and the first rotating cylinder 447 is greater than the friction coefficient between the second friction block 4411 and the second rotating cylinder 4410, the number of rotation circles of the first rotating cylinder 447 will be offset by a part by the second rotating cylinder 4410 that is in contact with it but rotates in the opposite direction. When the bearing plate 1 walks on the straight section of the spiral floor heating pipe, the rotation speeds of the left and right rollers 42 are the same, and the number of circles offset by the first rotating cylinder 447 by the second rotating cylinder 4410 is always fixed. Therefore, the first rotating cylinder 447 is in a uniform speed state at this time.

[0036] The rotation of the No. 1 rotating drum 447 drives the protrusion 434 to rotate. When the protrusion 434 rotates to contact the top column 435, it pushes the top column 435 to rise, and the top column 435 then pushes the cross rod 432 to rise, and the cross rod 432 rotates around the hinge point with the protruding rod 431, thereby causing the pressure rod 433 to fall, and the pressure rod 433 then pushes the U-shaped pin located directly below it and at the inclined position of the round rod 32 to fall. The pressed U-shaped pin and the inclined surface of the round rod 32 squeeze each other and push the round rod 32 to gradually retract into the guide rod 31. After the round rod 32 is completely retracted into the guide rod 31, the U-shaped pin then enters the strip groove and is also sleeved on the outside of the floor heating pipe. Then the pressure rod 433 continues to descend and presses the U-shaped pin into the foam plastic plate, thereby completing the fixation of the spiral middle straight section of the floor heating pipe. When it moves to the spiral bending section, the left roller 42 is in the inner diameter and the right roller 42 is in the outer diameter. At this time, the rotation speed of the right roller 42 is greater than that of the left roller 42, and the rotation speed of the No. 1 roller 447 driven by the two rollers 42 is greater than the rotation speed of the No. 2 roller 4410. The number of turns of the No. 1 roller 447 offset by the No. 2 roller 4410 is greatly reduced. At this time, the rotation speed of the No. 1 roller 447 is accelerated, and the frequency of the intermittent ejection component 43 being touched by the No. 1 roller 447 becomes faster, thereby increasing the frequency of nailing the U-shaped staples to the outside of the floor heating pipe, so that different numbers of U-shaped staples can be nailed according to the different positions of the laid floor heating pipes, so that the U-shaped staples at different positions are at a reasonable number, thereby enhancing the fixing effect, and at the same time facilitating the rapid fixation of the laid floor heating pipes, thereby improving the fixing efficiency of the floor heating pipes.

[0037] As the supporting plate 1 moves, the inverted U-shaped pressure hoop 2 is driven to move synchronously. The inverted U-shaped pressure hoop 2 can be used to straighten the floor heating pipes and arrange them neatly on the foam plastic board, thereby ensuring that the spacing between two adjacent sections of floor heating pipes after laying is equal.

[0038] During operation, first, the spacing of the inverted U-shaped clamp 2 is adjusted to match the spacing between the two adjacent sections of the floor heating pipe to be laid using the distance adjusting piece 8, then the inverted U-shaped clamp 2 is pressed against the outside of the floor heating pipe, and then the supporting plate 1 is pushed to move. At the same time, the driving member 4 runs synchronously with the movement of the supporting plate 1, thereby driving the intermittent ejection component 43 to run synchronously, and the intermittent ejection component 43 then cooperates with the blanking member 3 to nail the U-shaped clamping rod to the foam plastic board to clamp and fix the floor heating pipe, and utilizes the change in the difference in inner and outer diameters of the two rollers 42 in the driving member 4 when they move to different positions to nail different numbers of U-shaped staples to different positions of the laid floor heating pipe, which speeds up the installation speed and improves the fixing efficiency. The inverted U-shaped clamp 2 can also straighten the laying floor heating pipe while moving with the supporting plate 1, while also ensuring that the spacing between the two adjacent sections of floor heating pipe is equal, which improves the laying quality of the floor heating pipe.
