Description

Technical Field

[0001] The invention relates to the technical field of exterior wall sealing and waterproofing, and in particular to an assembled building exterior wall joint waterproofing construction device. Background Art

[0002] At present, prefabricated buildings are a development trend in the construction industry. This type of building has many advantages, including high construction quality and efficiency, not easily affected by climate, short construction period, energy saving and environmental protection, and is widely recognized by the industry and the general public. At present, prefabricated technology has been widely used in the construction industry, such as industrial plants, villas, large public buildings, especially multi-story residential buildings, which almost all adopt this technology to varying degrees.

[0003] There will be gaps between the walls of prefabricated buildings during assembly, and the width of the gaps varies depending on different assembly requirements. The current foaming agent spray gun only injects foaming agent into the gaps, and different nozzles need to be replaced according to the width of the gaps. For example, when the gap is narrow, a pointed nozzle needs to be replaced, and when the gap is wide, a flat nozzle needs to be replaced. This ensures the filling rate of the foaming agent while improving the uniformity of the injection. However, during assembly design and on-site installation, it cannot be guaranteed that the dimensions will meet the assembly requirements 100%. In this case, when the gap is too wide, it is necessary to reciprocate and inject several times in the gap. In order to ensure the filling rate, as much as possible will be injected into the gap, so the uniformity of the injection cannot be guaranteed. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] like Figures 1 to 5 As shown, the present embodiment provides an assembled building exterior wall joint waterproofing construction equipment, including a walking unit 10 and a lifting unit 11 installed on the top of the walking unit 10, and also includes:

[0045] A mounting seat 12, the mounting seat 12 is mounted on the lifting unit 11;

The driving motor 17 is installed on the mounting base 12 and is respectively connected to the flipping assembly 15 and the telescopic assembly 16.

[0047] The working principle and beneficial effects of the above technical solution are:

[0048] The present invention discloses an assembled building exterior wall joint waterproofing construction equipment. After the walking unit 10 drives the foaming agent injection unit 13 to move to a preset position, the lifting unit 11 works, thereby driving the foaming agent injection unit 13 to complete the foaming agent injection work in the gap along the height direction of the exterior wall. When a wider gap appears, the Y-shaped nozzle 14 is first adjusted to Figure 5 At this time, the lifting unit 11 drives the mounting base 12 to work from top to bottom, and the Y-shaped nozzle 14 injects the foaming agent to both sides of the gap, thereby completing the injection of both sides of the gap, and then the flip assembly 15 works, driving the Y-shaped nozzle 14 to adjust to the position as shown in the figure. Figure 1 state, at this time the lifting unit 11 drives the mounting seat 12 to work from bottom to top, the Y-shaped nozzle 14 injects the foaming agent into the middle of the gap, and then completes the injection into the middle of the gap, and then the telescopic component 16 works, driving the Y-shaped nozzle 14 to retreat a certain distance in the gap. At this time, just repeat the above actions, so that the filling rate and uniformity of the foaming agent in the wider gap can be guaranteed. The present invention provides an assembled building exterior wall joint waterproofing construction equipment, which utilizes the 90° flip of the Y-shaped nozzle 14 to complete the injection of the foaming agent first along both sides of the gap and then in the middle of the gap, thereby ensuring the filling rate and uniformity of the foaming agent in the wider gap.

[0049] Further, when the Y-shaped nozzle 14 is Figure 1 When the Y-shaped nozzle 14 is in the state, the foaming agent injection work for the narrow gap can also be completed. Figure 5 When the foaming agent is in the state of being opened, the foaming agent injection work for the wider gap can be completed. For the foaming agent injection for the wider gap, it is only necessary to control the advance and retreat depth of the Y-shaped nozzle 14. The wider the gap, the smaller the entry depth of the Y-shaped nozzle 14 can be. On the contrary, the narrower the gap, the greater the entry depth of the Y-shaped nozzle 14 can be. In this way, the uniformity of the foaming agent injection can be ensured.

[0073] A rotating rod 25, the rotating rod 25 is installed on the rotating disk 1 24;

[0074] A sliding block 26 is provided with an arc groove 27, and a transmission groove 28 is installed at the first and second ends of the arc groove 27.

Figure 5 As shown, when the rotating rod 25 on the rotating disk 1 24 rotates clockwise, the driving slider is in the transmission groove 28 above, and then drives the sliding block 26 and the end mounting frame 30 connected to the sliding block 26 to slide in the limiting groove 29, and the end mounting frame 30 drives the spline shaft 23 located in the spline sleeve 21 to slide, thereby driving the Y-shaped nozzle 14 installed on the spline shaft 23 to do a protruding movement, and when the driving slider moves to the transmission groove 28 below, it drives the sliding block 26 and the end mounting frame 30 connected to the sliding block 26 to slide in the limiting groove 29, and the end mounting frame 30 drives the spline shaft 23 located in the spline sleeve 21 to slide, thereby driving the Y-shaped nozzle 14 installed on the spline shaft 23 to do a retracting movement, so that the advance and retreat depth of the Y-shaped nozzle 14 can be changed. The advance and retreat depth of the Y-shaped nozzle 14 is controlled to achieve layer-by-layer filling of the foaming agent in a wider gap.

[0077] In one embodiment, the flip assembly 15 includes:

[0078] The turning roller 31 is rotatably mounted on the support frame 20. The two shaft ends of the turning roller 31 are both equipped with limiting discs 32. The limiting discs 32 are provided with limiting slots 33 facing each other.

[0079] A driving inclined groove 34 is spirally opened on the turning roller 31, and the limit bayonet 33 is connected to both ends of the driving inclined groove 34. The gear 22 is installed on an axial end of the turning roller 31 away from the support frame 20;

[0080] The driving assembly is mounted on the mounting seat 12 , the driving assembly is connected to the output end of the driving motor 17 , and the driving assembly is adapted to the limit bayonet 33 and the driving inclined slot 34 .

[0081] The drive components include:

[0082] A driving shaft, which is mounted on the mounting seat 12 via a supporting plate 35;

[0083] The second turntable 36 is mounted on the driving shaft, two levers 37 are mounted on the second turntable 36 opposite to each other, the levers 37 are adapted to the driving inclined slot 34, two arc-shaped clamping plates 38 are mounted on the second turntable 36 opposite to each other through connecting arms 39, the arc-shaped clamping plates 38 are adapted to the limit clamping ports 33, and the two levers 37 and the two connecting arms 39 are distributed on the second turntable 36 in a circular array;

[0084] The sprocket 40 and the transmission chain belt 41 are sleeved on two sprockets 40 , wherein one sprocket 40 is installed on the output end of the driving motor 17 , and the other sprocket 40 is installed on the driving shaft.

[0085] The working principle and beneficial effects of the above technical solution are:

[0086] The driving motor 17 located on the mounting seat 12 works, thereby driving the sprocket 40 and the transmission chain belt 41 installed at the output end of the driving motor 17 to cooperate, driving the driving shaft to rotate on the support plate 35, and the driving shaft drives the turntable 2 36 installed thereon to rotate, thereby driving the lever 37 and the connecting arm 39 distributed on the turntable 2 36 to rotate, and the lever 37 passes through the limiting bayonet 33 and enters the driving inclined groove 34, thereby driving the flip roller 31 to rotate, and then completing the 90° rotation of the flip roller 31, and the flip roller 31 drives the spline sleeve 21 and the spline shaft 23 located in the spline sleeve 21 to rotate through the meshing gear 22, thereby driving the Y-type nozzle 14 installed on the spline shaft 23 to rotate, and then realizing the 90° flipping of the Y-type nozzle 14, and then the arc-shaped clamping plate 38 is clamped on the limiting bayonet 33 of the limiting disc 32, thereby limiting the flip roller 31 to ensure that the Y-type nozzle 14 does not move.

[0087] Specifically, Figure 5 As shown, when the driving slide transitions from the upper transmission groove 28 to the arc groove 27, the Y-shaped nozzle 14 completes the extension action, and one of the levers 37 passes through the limit bayonet 33 and enters the driving inclined groove 34, and the Y-shaped nozzle 14 is simultaneously turned 90 degrees. The Y-shaped nozzle 14 injects the foaming agent to both sides of the gap, and the lifting unit 11 drives the mounting seat 12 to work from top to bottom, and the Y-shaped nozzle 14 injects the foaming agent to both sides of the first layer in the gap, thereby completing the injection of both sides of the gap.

[0088] When the driving slider slides the front half of the arc groove 27 , one of the arc clamping plates 38 is clamped on the limiting clamping opening 33 of the limiting disc 32 , and the Y-shaped nozzle 14 does not move.

[0089] When the driving slider slides to the rear half in the arc groove 27, the other lever 37 passes through the limit snap-in 33 and enters the driving inclined groove 34, and the Y-shaped nozzle 14 continues to turn 90 degrees, and then the other arc snap-in plate 38 is clamped on the limit snap-in 33 of the limit disc 32. At this time, the lifting unit 11 works in the reverse direction, driving the mounting seat 12 to work from bottom to top, and the Y-shaped nozzle 14 injects the foaming agent into the middle of the gap, thereby completing the injection into the middle of the gap.

[0090] When Figure 1 As shown in FIG. 1 , when the arc groove 27 of the driving slider transitions to the transmission groove 28 below, the lever 37 then passes through the limit bayonet 33 and enters the driving inclined groove 34, and the Y-shaped nozzle 14 is turned 90 degrees again. At the same time, the Y-shaped nozzle 14 is retracted and retreats a distance in the gap. The Y-shaped nozzle 14 remains as shown in FIG. Figure 5 At this time, the lifting unit 11 then drives the mounting base 12 to work from top to bottom, and the Y-shaped nozzle 14 injects the foaming agent to both sides of the gap, thereby completing the injection of both sides of the second layer in the gap.

[0091] In one embodiment, the drive motor 17 is mounted on the mounting base 12 via a motor mounting base 42 .

[0092] The beneficial effects of the above technical solution are:

[0093] The motor mounting seat 42 is provided to facilitate the installation of the driving motor 17 on the mounting seat 12 .

[0094] In one embodiment, a rotating drum is installed at the output end of the driving motor 17, and the surface of the rotating drum is marked with internal injection and external injection words in different colors. An observation port for observing the surface of the rotating drum is opened on the mounting seat 12, and a detector for detecting the external injection words is installed on the lifting seat 45.

[0095] The working principle and beneficial effects of the above technical solution are:

[0096] When the lifting unit 11 then drives the mounting base 12 to work from top to bottom, the Y-shaped nozzle 14 injects the foaming agent to both sides of the gap, and then completes the injection of both sides of the second layer in the gap. At this time, the driving motor 17 located on the mounting base 12 continues to work. At this time, the rotating rod 25 continues to flip clockwise, and the Y-shaped nozzle 14 continues to retract and retreats a distance in the gap. The lever 37 then passes through the limit bayonet 33 again and penetrates into the driving inclined groove 34. The Y-shaped nozzle 14 flips 90 degrees again, and the Y-shaped nozzle 14 then injects the foaming agent into the middle of the gap, thereby completing the middle injection of the second layer in the gap.

[0097] A rotating drum is installed at the output end of the driving motor 17. When the rotating drum rotates, the detector detects the color of the external injection words and sends a working instruction to the electric driving roller 19. The travel seat 18 moves toward the outer wall to make up for the distance that the Y-shaped nozzle 14 continues to retreat, thus completing the injection of the second layer in the gap. After the two layers of injection are completed, the work stops. The driving motor 17 works alone, so that the rotating rod 25 returns to the position of the transmission slot 28 above.

[0098] In general, after the two layers of injection are completed, the Y-shaped nozzle 14 flips over a circle. Among the different colored inner and outer injection words marked on the surface of the drum, the area of ​​the inner injection words is much larger than the area of ​​the outer injection words. For example, the color of the inner injection words is red, and the color of the outer injection words is green. The detector only sends a work instruction to the electric drive roller 19 when it detects the green words. Only when injecting the middle position of the second layer, the walking seat 18 needs to move toward the outer wall to make up for the distance that the Y-shaped nozzle 14 continues to retreat. When the injection of the middle position of the second layer is completed, the Y-shaped nozzle 14 stops injecting the foaming agent. At this time, the drive motor 17 works alone, so that the rotating rod 25 returns to the upper transmission groove 28.

[0099] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
