Detailed Implementation

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] Reference Figures 1-5 As shown, this embodiment of the invention proposes a roll material laying machine, including a moving carriage 1, a first roller 7, a second roller 8, a discharge chute 3, two rotating seats 601, and two moving plates 602, wherein:

[0044] The first roller 7 is used to insert new rolls of material, and the second roller 8 is used to insert rolls of material to be replaced.

[0045] The two ends of the discharge trough 3 are rotatably connected to the mobile vehicle 1, and the first roller shaft 7 is placed in the discharge trough 3;

[0046] The rotating seat 601 is located below the discharge trough 3. The rotating seat 601 is connected to the moving plate 602. The two ends of the second roller shaft 8 are respectively rotatably connected to the two rotating seats 601.

[0047] The movable plate 602 is slidably connected to the movable vehicle 1, and the movable plate 602 is driven to the discharge trough 3. Under the rotation drive of the discharge trough 3, the movable plate 602 can drive the two rotating seats 601 to move away from or closer to each other.

[0048] In this embodiment, the material changing mechanism 6 is composed of two rotating seats 601 and two moving plates 602. Driven by the rotation of the discharge trough 3, the moving plates 602 can drive the two rotating seats 601 to move away from or closer to each other, thereby completing the material changing of the waterproof membrane.

[0049] The roll material laying machine proposed in this embodiment is slidably connected to the moving vehicle 1 via the moving plate 602 and the conveying chute 3. Under the rotation drive of the conveying chute 3, the moving plate 602 can drive the two rotating seats 601 to move away from each other. The two rotating seats 601 move away from each other until they are no longer in contact with the second roller shaft 8, and the second roller shaft 8 is removed. The two rotating seats 601 move closer together, and the conveying chute 3 rotates so that the first roller shaft 7 falls into the two rotating seats 601, realizing the replacement of the roll material. The replacement of the roll material is convenient and quick, and there is no need for manual handling of the roll material, saving time and effort.

[0050] In one embodiment, such as Figure 3 and Figure 4 As shown, the roll material laying machine also includes a gear shaft 606, a first gear 609, and a rack 604;

[0051] The gear shaft 606 is rotatably mounted on the mobile vehicle 1 and fixed in the axial direction of the gear shaft 606. The gear shaft 606 is connected to the discharge chute 3 in a transmission manner.

[0052] The first gear 609 is connected to one end of the gear shaft 606;

[0053] The rack 604 meshes with the first gear 609. A slider 605 is provided on the rack 604. A drive groove 603 is provided on the moving plate 602. The slider 605 is slidably connected to the drive groove 603 to drive the rotating seat 601 to move along the axial direction of the second roller shaft 8.

[0054] In this embodiment, the gear shaft 606 is connected to the discharge trough 3 for transmission. The discharge trough 3 drives the gear shaft 606 to rotate. The rack 604 meshes with the first gear 609. The first gear 609 drives the rack 604 to move linearly. The slider 605 on the rack 604 is slidably connected to the drive groove 603. Since the rack 604 is restricted to linear movement only in the vertical direction, the drive groove 603 moves horizontally relative to the rack 604 to drive the rotating seat 601 to move axially along the second roller shaft 8, thereby realizing the relative distance or proximity of the two rotating seats 601.

[0055] Of course, the transmission connection between the gear shaft 606 and the moving plate 602 is not limited to the above scheme. In some other embodiments, the gear shaft 606 and the moving plate 602 can also be driven by a crank-slider mechanism and a cam mechanism, as long as the rotational motion of the discharge trough 3 can be converted into the linear motion of the moving plate 602.

[0056] In one embodiment, such as Figure 4 As shown, the drive groove 603 includes a first sliding groove 6031, a second sliding groove 6032 and a third sliding groove 6033;

[0057] The first chute 6031 is located above the second chute 6032, and the first chute 6031 and the second chute 6032 are perpendicular to the axis of the second roller shaft 8 and parallel to each other;

[0058] The distance from the end of the movable plate 602 connected to the rotating seat 601 to the second slide groove 6032 is less than the distance to the first slide groove 6031;

[0059] The third slide 6033 is connected to the first slide 6031 and the second slide 6032 respectively.

[0060] In this embodiment, the first slide groove 6031 is located above the second slide groove 6032. The first slide groove 6031 and the second slide groove 6032 are perpendicular to the axis of the second roller shaft 8. The first slide groove 6031 and the second slide groove 6032 have a certain distance in the vertical and horizontal directions. The slider 605 slides between the first slide groove 6031 and the second slide groove 6032. The rack 604 is restricted to move only in a straight line in the vertical direction. The drive groove 603 moves in the horizontal direction relative to the rack 604, so as to drive the rotating seat 601 to move along the axial direction of the second roller shaft 8, thereby realizing the relative distance or proximity of the two rotating seats 601.

[0061] In one embodiment, such as Figure 2 and Figure 3 As shown, the roll material laying machine also includes a second gear 610, a first limiting rod 607 and a second limiting rod 608, wherein the first limiting rod 607 and the second limiting rod 608 are provided with tooth grooves and respectively mesh with the second gear 610;

[0062] The first limiting rod 607 and the second limiting rod 608 are perpendicular to the axis of the first roller 7 and parallel to each other. The first limiting rod 607 is used to support the first roller 7.

[0063] The second limiting rod 608 is located below the first limiting rod 607 and is used to support the second roller shaft 8.

[0064] In this embodiment, by setting the first limiting rod 607 and the second limiting rod 608 to have toothed grooves and respectively meshing with the second gear 610, during the process of the discharge chute 3 rotating to remove the first roller 7, the second gear 610 rotates in the forward direction, and the first limiting rod 607 and the second limiting rod 608 move in opposite directions. The first limiting rod 607 carries the first roller 7, and the second limiting rod 608 carries the second roller 8. During the process of the discharge chute 3 resetting, the two rotating seats 601 approach each other, and the second gear 610 rotates in the opposite direction, driving the first limiting rod 607 to move in the opposite direction to cancel its contact with the first roller 7. The first roller 7 falls into the two rotating seats 601, realizing automatic material replacement of the roll material. This is not only convenient and fast, but also eliminates the need for manual intervention in the process of replacing the old roll material and installing the new roll material, saving time and effort.

[0065] In one embodiment, such as Figure 3 and Figure 4 As shown, the roll material laying machine further includes a first pulley 611, a second pulley 612, and a belt 613. The first pulley 611 is connected to the discharge chute 3. The second pulley 612 is disposed on the gear shaft 606 and is located between the first gear 609 and the second gear 610. The belt 613 is driven to connect the first pulley 611 and the second pulley 612.

[0066] In this embodiment, the first pulley 611 and the second pulley 612 are connected by a belt 613. The first pulley 611 drives the second pulley 612 to rotate, thereby realizing that the discharge trough 3 drives the gear shaft 606 to rotate. The belt drive can make the discharge trough 3 and the gear shaft 606 rotate synchronously, thereby realizing the synchronous unloading of the first roller shaft 7 from the discharge trough 3 and the unloading of the second roller shaft 8 from the rotating seat 601, which can save the material changing time.

[0067] Of course, the connection between the gear shaft 606 and the discharge trough 3 is not limited to the above scheme. In some other embodiments, the gear shaft 606 and the discharge trough 3 can also be driven by gear transmission, synchronous belt transmission, etc., as long as the synchronous rotation of the discharge trough 3 and the gear shaft 606 can be achieved.

[0068] Based on the above technical solutions, the preferred option is, for example... Figure 1 and Figure 2As shown, the roll material laying machine also includes a rotating rod 4 and a resetting component 5. The rotating rod 4 is connected to the discharge chute 3. The resetting component 5 is mounted on the moving vehicle 1 and connected to the rotating rod 4. The resetting component 5 can accumulate a rebound force during the rotation of the rotating rod 4 under force. After the force is released, the rotating rod 4 can reset under the action of the rebound force. In this embodiment, the resetting component 5 is a spring. By applying an external force to rotate the rotating rod 4, the resetting component 5 accumulates a rebound force during the rotation of the rotating rod 4 under force. After the external force is released, the rotating rod 4 quickly resets under the action of the rebound force, thereby realizing the forward and reverse rotation of the discharge chute 3, driving the rotating shaft to quickly rotate forward and reverse, realizing rapid roll material replacement, and improving efficiency.

[0069] In one embodiment, the rotating base 601 is provided with mounting grooves, and the two ends of the second roller shaft 8 are respectively placed in the two mounting grooves. The mounting grooves provided by the rotating base 601 are semi-circular in shape, which facilitates the placement of the second roller shaft 8. The second roller shaft 8 can rotate in the mounting grooves, which facilitates the unloading of the roll material from the second roller shaft 8. The second roller shaft 8 is placed in the mounting grooves without the use of other fixing structures, and the second roller shaft 8 can be removed by simply disengaging the rotating base 601 from contact with it, which is relatively convenient and quick.

[0070] In one embodiment, such as Figure 4 As shown, the roll material laying machine also includes an adjusting bolt 10, which is threadedly connected to the rotating seat 601 and can abut against the second roller shaft 8. By abutting against the second roller shaft 8 with the adjusting bolt 10, the rotational resistance of the second roller shaft 8 can be increased, making it easier to straighten the waterproof roll material and improve the laying effect.

[0071] In one embodiment, such as Figure 2 As shown, the mobile vehicle 1 includes a frame 101, and the roll material laying machine also includes an inclined plate 2. The inclined plate 2 is inclinedly disposed in the frame 101 and is used to store multiple first rollers 7. The lowest end of the inclined plate 2 leads to the discharge chute 3. The rotating rod 4 is provided with a baffle, which is located above the lowest end of the inclined plate 2 and is used to block the bottommost first roller 7 on the inclined plate 2. By storing multiple first rollers 7 through the inclined plate 2 and the baffle on the rotating rod 4, each rotation of the rotating rod 4 allows the first roller 7 to enter the discharge chute 3. The rotating rod 4 then resets and continues to block the bottommost first roller 7 on the inclined plate 2, thus providing one first roller 7 to the discharge chute 3 each time.

[0072] In one embodiment, such as Figure 1 and Figure 2As shown, the mobile vehicle 1 also includes at least two compaction rollers 102, which are disposed at the bottom of the vehicle frame 101. By disposing of the compaction rollers 102 at the bottom of the vehicle frame 101, the vehicle frame 101 can be moved, and the compaction rollers 102 compact the waterproof membrane.

[0073] In one embodiment, such as Figure 1 and Figure 5 As shown, the roll material laying machine also includes an adhesive application assembly 9, which includes a storage tank 901, a connecting pipe 902, and multiple discharge pipes 903. The storage tank 901 is connected to the frame 101. The two ends of the connecting pipe 902 are respectively connected to the storage tank 901 and the multiple discharge pipes 903, and the outlets of the discharge pipes 903 face the second roller shaft 8. The two ends of the connecting pipe 902 are connected to the storage tank 901 and the multiple discharge pipes 903, and a switch valve is installed on the connecting pipe 902. When the switch valve is opened, adhesive is applied to the waterproof roll material through the multiple discharge pipes 903, facilitating the adhesion of the waterproof roll material to the ground.

[0074] In one embodiment, such as Figure 2 As shown, a counterweight box 104 is provided in the frame 101. By providing a counterweight box 104 in the frame 101, tools related to waterproofing work can be placed in the counterweight box 104 to increase the weight of the mobile vehicle 1, thereby indirectly increasing the compaction effect of the compaction roller 102 on the waterproof membrane.

[0075] In one embodiment, such as Figure 2 As shown, the mobile vehicle 1 also includes a handrail 103, which is mounted on the frame 101. By mounting the handrail 103 on the frame 101, the handrail 103 and the rotating rod 4 are located on opposite sides of the frame 101. Pushing the handrail 103 can move the frame 101, facilitating the application of thrust.

[0076] In one embodiment, the diameter of the middle portion of the first roller 7 and the second roller 8 is larger than the diameters at both ends. The smaller diameter at both ends facilitates the insertion of the rollers into the waterproof membrane, while the larger diameter in the middle improves the stability of the connection between the first roller 7 and the second roller 8 and the waterproof membrane, thereby enhancing the stability of the device.

[0077] The working principle of this roll material laying machine is:

[0078] A new waterproof membrane is inserted into the first roller shaft 7, and the membrane to be replaced is fitted onto the second roller shaft 8. The first roller shaft 7 is placed on the inclined plate 2, and it will roll downwards onto the discharge chute 3. The hand-held rotating rod 4 drives the discharge chute 3 to rotate counterclockwise. The discharge chute 3 drives the gear shaft 606 to rotate via the belt 613, the first pulley 611, and the second pulley 612. The first gear 609 at one end of the gear shaft 606 drives the rack 604 to move downwards, and the second gear 610 at the other end drives the first limit rod 607 to move to the left and the second limit rod 608 to move to the right. When the rotating rod 4 rotates to the first half of its stroke, the slider 605 pushes the inner wall of the drive groove 603, causing the moving plate 602 and its fixed rotating seat 601 to move outwards, so that the two rotating seats 601 move away from each other, thereby allowing the two rotating seats to move outwards. The second roller 8 between seats 601 can be freed from the obstruction of the rotating seat 601 and thus only contact the second limiting rod 608 below it. At the same time, the second gear 610 at the other end of the gear shaft 606 will drive the first limiting rod 607 and the second limiting rod 608 to move in opposite directions. The left end faces of the first limiting rod 607 and the second limiting rod 608 are on the same vertical line as the center of the rotating seat 601. When the rotating rod 4 rotates to the second half of the stroke, the slider 605 cooperates with the second sliding groove 6032 of the drive groove 603 to keep the moving plate 602 stationary. At the same time, the left end of the first limiting rod 607 is located on the left side of the rotating seat 601 and is used to receive the first roller 7 in the middle of the waterproof roll material rolling off the discharge chute 3. The left end of the second limiting rod 608 is located on the right side of the rotating seat 601 and is used to release the first roller 7 originally in the rotating seat 601.

[0079] When the reset component 5 drives the rotating rod 4 to rotate in the opposite direction to reset, the upper first limiting rod 607 slides in the opposite direction to cancel its contact with the current first roller 7, and the first roller 7 falls off the first limiting rod 607. The lower second limiting rod 608 moves in the opposite direction to receive the fallen first roller 7. Then the two rotating seats 601 approach each other and connect with the end of the first roller 7 to realize the replacement of the first roll and the second roll. Thus, the rapid automatic material change of the roll material is realized.

[0080] The waterproof membrane on the first roller shaft 7 connected to the rotating seat 601 is pulled out from the free end and placed between the compaction roller 102 on the left side and the ground. The switch valve on the connecting pipe 902 is opened, and the glue is applied to the waterproof membrane through multiple discharge pipes 903. The trolley moving vehicle 1 moves, so that the waterproof membrane is automatically released and glue is applied, and it is compacted by the compaction roller 102 to realize the laying of the waterproof membrane.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
