[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figures 1-3 , a building construction wire laying device with a protection function includes a winder 1, a pulling pipe 2 is installed at one end of the winder 1, a connecting frame 3 is connected to one end of the pulling pipe 2, a slide bar 4 is installed at one end of the connecting frame 3, and a clamp 5 is installed at one end of the slide bar 4;

[0035] A triggering device 6 is installed inside the connecting frame 3. The triggering device 6 includes a push plate 68 arranged inside the connecting frame 3. A placement cavity 11 is arranged inside the connecting frame 3. A number of pulley devices 14 are arranged inside the placement cavity 11. Pulley devices 14 are arranged at both ends of the connecting frame 3. The pulley devices 14 communicate with the placement cavity 11. The push plate 68 is used to squeeze the pulley device 14 to one end of the blanking port 13;

[0036] The pulley device 14 includes a pulley frame, a second pulley, a thin film and a magnet. A second pulley is rotatably connected to one end of the pulley frame. A thin film is installed at the other end of the pulley frame. Glue is arranged between the thin film and the pulley frame. A magnet is also installed at the other end of the pulley frame.

[0037] According to Figure 1 As shown, first move the winder 1 to the wire outlet. Subsequently, place the connecting frame 3 on the bridge. Transmit air to the drawtube 2 through an air pump, so as to expand the drawtube 2 through the air, so that the drawtube 2 wound inside the winder 1 pushes the connecting frame 3 to slide, so that the connecting frame 3 slides to the wire inlet. According to Figure 2 As shown, place a number of wires at the fixture 5. Clamp and fix a number of wires through the fixture 5. Subsequently, recycle the drawtube 2 inside the winder 1 and rewind it inside the winder 1, so as to pull the drawtube 2 to slide the connecting frame 3 towards the wire outlet through the drawtube 2, and the connecting frame 3 pulls the fixture 5 and the wires to slide towards the wire outlet;

[0038] According to Figure 3 As shown, when the friction between the connecting frame 3 and the wire bridge is large, it indicates that the wires connected to the connecting frame 3 will also have friction with the wire bridge subsequently. Therefore, push the pulley device 14 to slide to one side through the push plate 68, so that the pulley device 14 slides out of the blanking port 13 and abuts the pulley device 14 against the inner wall of the wire bridge. The pulley device 14 is adhered to the wire bridge through the magnet on the pulley device 14. Subsequently, the thin film on one side of the pulley device 14 will rupture, so that the glue inside the thin film flows out, so that the pulley device 14 is fixed to the wire bridge through the glue again. In this way, it is ensured that when the subsequent wire rubs against the pulley device 14, the glue has fixed the pulley device 14 to the inner wall of the wire bridge. In this way, the wire is protected through the pulley device 14. When the connecting frame 3 rubs against the wire bridge, install the pulley device 14 on the wire bridge. The second pulley on the pulley device 14 contacts the wire, so as to reduce the friction, thereby reducing the risk of the wire being pulled and broken.

[0039] Embodiment 2

[0040] This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1-3, an auxiliary device 7 is also installed inside the winder 1. The auxiliary device 7 includes an airbag roll 72 rotatably connected inside the connecting frame 3. A rotating rod 71 is installed inside the airbag roll 72. One end of the airbag roll 72 penetrates through the connecting frame 3, and one end of the airbag roll 72 is used to insert into the gap between the wire and the cable tray.

[0041] According to Figure 3 As shown, when the connecting frame 3 rubs against the wire bridge, by filling air into the airbag roll 72, the airbag roll 72 expands, slides out of the inside of the connecting frame 3, and the airbag roll 72 is located on both sides of one end of the fixture 5. Subsequently, the airbag roll 72 is inserted into the gap between the wire and the cable tray, thereby squeezing the wire to shift and reducing the friction between the wire and the wire bridge.

[0042] Embodiment 3

[0043] This embodiment is an improvement based on Embodiment 2. Specifically, please refer to Figures 1-3 , a first roller 73 is installed on one side of the airbag roll 72, and the first roller 73 is used to abut against the pulley device 14.

[0044] Furthermore, since the glue of the pulley device 14 needs a certain time to cure to adhere the pulley device 14 to the wire bridge, in order to prevent the airbag roll 72 from squeezing the pulley device 14 to shift due to the wire, a first roller 73 is installed on one side of the airbag roll 72. According to Figure 3 As shown, when the airbag roll 72 is inserted into the gap between the wire and the wire bridge, and after the pulley device 14 is installed on the wire bridge with glue, as the connecting frame 3 continues to slide towards the wire outlet, the first roller 73 is used to abut against the second roller of the pulley device 14, so as to reduce the friction between the airbag roll 72 and the pulley device 14, thereby increasing the curing time of the glue and ensuring that the pulley device 14 can be fixed on the wire bridge.

[0045] Embodiment 4

[0046] This embodiment is an improvement based on Embodiment 3. Specifically, please refer to Figures 1-3 , the triggering device 6 further includes a push rod 61 slidably connected inside the connecting frame 3. The push rod 61 penetrates through both sides of the connecting frame 3, and two force-receiving blocks 63 are installed at one end of the push rod 61;

[0047] Two short shafts 65 are also installed inside the connecting frame 3. One end of the short shaft 65 is installed with a first block 64, and the other end of the first block 64 is installed with a second block 66. The force-receiving block 63 is used to squeeze the first block 64 to swing towards one end. One end of the push plate 68 is installed with a cylinder 67, and one end of the second block 66 is used to abut against one end of the cylinder 67;

[0048] One end of the push plate 68 is further provided with a third spring 69, and one end of the third spring 69 is connected to the inner wall of the connecting frame 3;

[0049] The size of the third spring 69 is adapted to the size of the blanking port 13.

[0050] According to Figure 3 As shown, when the push rod 61 on the connecting frame 3 abuts against the inner wall of the wire cable tray, the inner wall of the wire cable tray will squeeze the push rod 61 to slide to one side. The push rod 61 drives the force receiving block 63 to abut against the first block 64. The first block 64 drives the short shaft 65 and the second block 66 to swing to the other side. By the second block 66 abutting against the cylinder 67, the second block 66 squeezes the cylinder 67 to slide to one side. By the cylinder 67 pushing the push plate 68 to slide to one side, in this way, the push plate 68 squeezes the pulley device 14 to slide towards the inner wall of the wire cable tray, so that the pulley device 14 adheres to the inner wall of the wire cable tray. In this way, the automatic installation of the pulley device 14 on the inner wall of the wire cable tray is realized;

[0051] It should be particularly noted that the push rod 61 penetrates through both ends of the connecting frame 3. When the wire cable tray squeezes the push rod 61 at the left end or the right end, the push rod 61 at the left end will trigger to squeeze the push plate 68 inside the left connecting frame 3, and the push rod 61 at the right end will trigger to squeeze the push plate 68 inside the right connecting frame 3;

[0052] A steel coil is further installed inside the airbag roll 72;

[0053] The length of the hose 74 is the same as the length of the airbag roll 72;

[0054] A push-pull plate 12 is further installed inside the placement cavity 11. The push-pull plate 12 is used to abut against the pulley device 14, and the push-pull plate 12 is connected to the connecting frame 3 through a second spring 15.

[0055] Embodiment 5

[0056] This embodiment is an improvement made on the basis of Embodiment 4. Specifically, please refer to Figures 1-3 , an air pressure device 8 is provided inside the connecting frame 3. The air pressure device 8 includes a square cavity 81 provided inside the connecting frame 3. A piston plate 82 is slidably connected inside the square cavity 81. The piston plate 82 is connected to the connecting frame 3 through a fourth spring 83;

[0057] A first groove 76 and a second groove 78 are further provided inside the connecting frame 3. The first groove 76 is provided at one end of the second groove 78. One end of the push rod 61 is provided with a connecting rod 62. Square rods 75 are installed on both sides of the connecting rod 62. One side of the square rod 75 is slidably connected to the sealing plate 77 at the second groove 78. A circulation hole 79 is further installed inside the connecting frame 3. The lower end of the circulation hole 79 is communicated with the first groove 76, and the upper end of the circulation hole 79 is communicated with the square cavity 81;

[0058] A hose 74 is also installed inside the connecting frame 3. One end of the hose 74 communicates with the inside of the first groove 76, and the other end of the hose 74 is connected to one end of the airbag roll 72.

[0059] According to Figure 3 As shown, when the push rod 61 slides, the push rod 61 will also drive the connecting rod 62 to slide. The connecting rod 62 drives the square rod 75 to slide to one side, so that the square rod 75 drives the sealing plate 77 to slide to the first groove 76, making the first groove 76 communicate with the second groove 78. According to Figure 4 As shown, since the first groove 76 communicates with the second groove 78 and the first groove 76 communicates with the hose 74, then the piston plate 82 is pushed by the fourth spring 83 to slide to one end. In this way, the air inside the square cavity 81 is squeezed by the piston plate 82 to the flow hole 79. The flow hole 79 transmits the air to the second groove 78, the second groove 78 transmits the air to the hose 74, and the hose 74 transmits the air to one end of the airbag roll 72, thereby inflating the airbag roll 72 so that the airbag roll 72 can be inserted into the gap between the wire and the cable tray.

[0060] Embodiment 6

[0061] This embodiment is an improvement made on the basis of Embodiment 5. Specifically, please refer to Figures 1-5 , a sliding cylinder 89 is installed at one end of the connecting frame 3. One end of the sliding cylinder 89 is connected to the pulling pipe 2. The pulling pipe 2 is used to transmit air to the square cavity 81 through the sliding cylinder 89. A deflation groove 84 is also installed inside the connecting frame 3. The deflation groove 84 penetrates through the connecting frame 3, and the piston plate 82 is used to slide to the deflation groove 84;

[0062] A sixth spring 88 is arranged inside the connecting frame 3. The sixth spring 88 is arranged between the square cavity 81 and the sliding cylinder 89. A return spring is also installed at one end of the sliding cylinder 89. The sliding cylinder 89 is connected to the connecting frame 3 through the return spring;

[0063] Squeezing blocks 85 are installed at both ends of the sliding cylinder 89. A conical column 86 is installed inside the connecting frame 3. A fifth spring 87 is installed at the upper end of the conical column 86. The conical column 86 is connected to the connecting frame 3 through the fifth spring 87. The squeezing block 85 is used to squeeze the conical column 86 to slide, and the conical column 86 is used to abut against the first block 64.

[0064] According to Figure 4 and Figure 5As shown, since the air pump transmits air to the drawtube 2, the drawtube 2 extends to push the connecting frame 3 to slide to the wire inlet. Subsequently, when the connecting frame 3 pulls the wire and slides towards the wire outlet, since the winder 1 will wind up the drawtube 2 and wind it again inside the winder 1, the air inside the drawtube 2 will be squeezed to the sixth spring 88. Due to excessive air pressure, the sixth spring 88 will be opened, allowing air to enter the square cavity 81. When the square cavity 81 is filled, the piston plate 82 will slide to the air release groove 84. Since the size of the air release groove 84 is larger than that of the square cavity 81, the air in the square cavity 81 will flow into the air release groove 84 and be discharged to relieve the pressure. When it is necessary for the connecting frame 3 to rub against the wire bridge, after using a part of the air inside the square cavity 81, at this time, the winder 1 will wind up the drawtube 2, so that the drawtube 2 will transmit and squeeze the air inside again to open the sixth spring 88 and enter the square cavity 81, so as to fill the square cavity 81 and facilitate the next expansion airbag roll 72 to use the air in the square cavity 81;

[0065] Furthermore, when the connecting frame 3 does not rub against the wire bridge, but when the wire generates resistance, the drawtube 2 will pull the sliding cylinder 89 to slide, and the sliding cylinder 89 will drive the extrusion block 85 to move. By the extrusion block 85 abutting against the conical column 86, the conical column 86 is squeezed to slide downward by the extrusion block 85. Through the conical column 86 squeezing the force-receiving block 63 to slide towards one end, the force-receiving block 63 is used to squeeze one end of the first block 64, so as to execute the push plate 68 in Embodiment 4 to push the pulley device 14 to adhere to the inner wall of the wire bridge;

[0066] It should be particularly noted that extrusion blocks 85 are installed at both ends of the sliding cylinder 89, and the extrusion blocks 85 at both ends are staggered. In this way, the extrusion block 85 on the left is used to squeeze the conical column 86 to slide downward first. Subsequently, when the friction between the wire and the wire bridge continues to increase, the sliding cylinder 89 will slide towards one end again. In this way, the extrusion block 85 at the right end of the sliding cylinder 89 will abut against another conical column 86 to slide downward, so that the two pulley devices 14 adhere to the wire bridge alternately, so as to further reduce the friction between the wire and the wire bridge.

[0067] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0068] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
