Detailed implementation manners

[0017] Please refer to Figures 1-11 , the present invention provides a technical solution: a coiled material paving auxiliary support for building engineering waterproofing, including a frame 1, a material box 2 and a box body 3. A roller 4 and a pressure roller 5 are installed on the frame 1; the material box 2 is fixedly connected to the frame 1 and multiple waterproof coiled materials are contained in the material box 2; A blanking mechanism is provided in the material box 2. The blanking mechanism is used to sequentially feed the waterproof coiled materials in the material box 2 into the box body 3 and unfold the head part of the waterproof coiled material during the blanking process; The box body 3 is vertically elastically slidably connected to the frame 1 and two groups of conveyor belts 11 are provided in the box body 3. The two groups of conveyor belts 11 are used to transfer the head of the waterproof coiled material in the box body 3 to the position of the pressure roller 5 and the paving is completed by the pressure roller 5; A docking unit is provided in the box body 3. The docking unit is used to drive the two groups of conveyor belts 11 to dock and clamp the head part of a new roll of waterproof coiled material with the end part of the previous roll of waterproof coiled material when the blanking mechanism is feeding materials; As Figures 1-3 shown, during work, by winding the waterproof coiled material around a winding roller and then putting the coiled material into the material box 2. During paving, first start the blanking mechanism to transport a roll of waterproof coiled material in the material box 2 into the box body 3, and then drive the whole device to move forward while the two groups of conveyor belts 11 transfer the head of the waterproof coiled material to the position of the pressure roller 5; Since the blanking mechanism will unfold the head part of the waterproof coil material during blanking, when the waterproof coil material reaches inside the box body 3, the two groups of conveyor belts 11 will traction and transport the unfolded head part of the waterproof coil material to a position close to the pressing roller 5 and fitting the ground; Since the pressing roller 5 will rotate while fitting the ground as the overall equipment moves forward, the pressing roller 5 will directly press on the waterproof coil material fitting the ground part. The waterproof coil material will be flatly attached to the ground under the pressing of the pressing roller 5 and will continuously pull the waterproof coil material under the action of the pressing roller 5, so as to achieve the effect of laying the waterproof coil material flat on the ground; Since the waterproof coil material needs to be continuously laid without gaps, when a roll of waterproof coil material is laid, at this time the blanking mechanism will lower a new roll of waterproof coil material into the box body 3, and the docking unit will dock the initial part of the new roll of waterproof coil material with the end part of the previous roll of waterproof coil material and transport them to the position of the pressing roller 5 together, and then the two spliced waterproof coil materials will be pressed and laid on the ground through the pressing roller 5, which can achieve the effect of continuously and uninterruptedly laying the waterproof coil material and can effectively improve the laying efficiency of the waterproof coil material; Combined Figure 11 When the overall equipment moves to the right, the pressing roller 5 will press and lay the waterproof coil material on the ground, and the waterproof coil material a on the box body 3 will be continuously consumed. When the waterproof coil material a on the box body 3 is consumed, the waterproof coil material a will automatically fall off; at the same time, the blanking mechanism will transfer the new waterproof coil material b in the material frame 2 downward to the box body 3, and during the transfer process, a part of the head part of the waterproof coil material b will unfold; while the blanking mechanism is blanking, the docking component drives the conveyor belt 11 on the right side to rotate and unfold. When the conveyor belt 11 on the right side unfolds, the locking mechanism locks the two groups of conveyor belts 11, and the two groups of conveyor belts 11 clamp the tail part of the waterproof coil material a. The tail part of the waterproof coil material a is stationary relative to the box body 3. As the overall equipment continues to move to the right, the pressing roller 5 pulls the box body 3 downward through the tail part of the waterproof coil material a, and the tail part of the waterproof coil material a is located in the lower part of the box body 3 and continues to be normally laid; when the waterproof coil material b is transferred downward to the box body 3, the unfolded head part of the waterproof coil material b naturally falls to the position between the two groups of conveyor belts 11, and the docking component drives the front conveyor belt 11 to reset. After the front conveyor belt 11 is reset, the two groups of conveyor belts 11 resume transmission and dock and clamp the tail part of the waterproof coil material a and the head part of the waterproof coil material b together. At this time, the box body 3 just moves to the bottommost position and is clamped by the clamping mechanism. As the overall equipment moves forward, the pressing roller 5 pulls the tail part of the waterproof coil material a downward, and the tail part of the waterproof coil material a pulls the head part of the waterproof coil material b downward through the two groups of conveyor belts 11. The head part of the waterproof coil material b is finally pressed and laid on the ground by the pressing roller 5. At this time, the box body 3 can be automatically reset by the reset mechanism.

[0018] As a further solution of the present invention, the unloading mechanism includes a baffle 6 installed at the bottom of the material frame 2, and the baffle 6 is electrically driven by a sensor; both ends of the winding roller of the waterproof coiled material in the material frame 2 are fixedly connected to gears 7; a rotating mechanism is provided at the bottom of the material frame 2, and the rotating mechanism is used to drive the corresponding gear 7 to rotate when the waterproof coiled material is unloaded; The rotating mechanism includes two guide rods 8 symmetrically arranged on the left and right sides of the material frame 2, the bottom ends of the guide rods 8 are tilted forward and fixedly connected to the box body 3, the upper ends of the guide rods 8 are located in the material frame 2 and the guide rods 8 are in contact with the winding roller of the waterproof coiled material; a rack 9 is fixedly connected to the guide rods 8, and the rack 9 is meshed with the gear 7; a blocking roller 10 is arranged above the inclined parts of the two guide rods 8, and the two ends of the blocking roller 10 are respectively rotatably connected to the two racks 9; the vertical distance between the blocking roller 10 and the inclined part of the guide rod 8 is equal to the diameter of the winding roller of the waterproof coiled material; When working, see Figures 4-5 , Figure 8 , Figure 10 When the waterproof coiled material on the box body 3 is consumed, the winding roller of the waterproof coiled material will fall from under the blocking roller 10. When the sensor detects that the winding roller of the waterproof coiled material in the box body 3 has fallen, the baffle 6 on the material frame 2 is opened. Under the action of the guide rod 8, a roll of waterproof coiled material in the material frame 2 will fall downward along the guide rod 8. During the falling process, the gear 7 on the winding roller of the waterproof coiled material will rotate under the action of the rack 9, thereby causing the entire waterproof coiled material to rotate, and the initial end of the waterproof coiled material will automatically unfold.

[0019] As a further solution of the present invention, two sets of conveyor belts 11 are parallel to each other and vertically arranged in the box body 3, the distance between the two sets of conveyor belts 11 is equal to the thickness of the waterproof coiled material and both are transmission-connected to the box body 3; the rear conveyor belt 11 is located directly above the pressure roller 5 and the width of the conveyor belt 11 is equal to the diameter of the pressure roller 5; When working, see Figures 4-6 The two sets of conveyor belts 11 can provide directional conveyance for the waterproof coiled material, thereby ensuring that the unfolded portion of the waterproof coiled material is transported to the position where the laminating and pressing rollers 5 are located.

[0020] As a further solution of the present invention, the docking unit includes a sliding frame 12 symmetrically distributed on both sides of the box body 3 and capable of rotatably supporting the transmission shaft of the conveyor belt 11; the sliding frame 12 is rotatably connected to the box body 3 and the rotating pair is coaxial with the lower transmission shaft of the conveyor belt 11; the box body 3 is provided with a cylinder 13 for driving the sliding frame 12 to rotate, and the cylinder 13 is started by a sensor control; the sliding frame 12 is provided with a locking mechanism, and the locking mechanism is used to lock the upper side rotation shaft of the front conveyor belt 11 when the cylinder 13 pushes the sliding frame 12; the frame 1 is provided with a clamping mechanism, and the clamping mechanism is used to clamp the box body 3 at the lowest position when the box body 3 moves downward; The locking mechanism includes two chutes 14 penetrating through the left and right inner walls of the box body 3. The chutes 14 are in an arc shape with the axis of the sliding frame 12 as the center and the length of the sliding frame 12 as the radius. The upper part of the sliding frame 12 is slidably connected to the chute 14; a turntable 15 is rotatably connected to the upper side of the sliding frame 12. The turntable 15 is fixedly connected to the upper shaft of the front conveyor belt 11. Friction blocks 16 are symmetrically arranged at the upper and lower positions of the turntable 15. The friction blocks 16 are slidably connected to the sliding frame 12 and two first springs 17 are connected between the two friction blocks 16; two arc-shaped pressing plates 18 are fixedly connected to the box body 3 at positions outside the chutes 14. The upper and lower friction blocks 16 are respectively attached to the end positions of the upper and lower arc-shaped pressing plates 18; During operation, refer to Figures 6-7 , when the waterproof coiled material in the box body 3 is consumed, the waterproof coiled material winding roller will pass through the blocking roller 10 and fall downward. After the sensor detects the fall of the waterproof coiled material winding roller, the driving cylinder 13 is activated. The cylinder 13 pushes the sliding frame 12 to rotate forward, and the sliding frame 12 drives the two frictions to move forward. When the friction blocks 16 move forward, they will be squeezed by the two arc-shaped pressing plates 18; when the two friction blocks 16 completely move to the positions inside the two arc-shaped pressing plates 18, at this time, the two friction blocks 16 just completely fit with the turntable 15, and the friction blocks 16 lock the turntable 15 at this time. As a result, the rear conveyor belt 11 cannot drive. Correspondingly, since the front and rear conveyor belts 11 are in a state of clamping the waterproof coiled material at this time, the rear conveyor belt 11 cannot rotate either, and the waterproof coiled material is relatively stationary relative to the two groups of conveyor belts 11; Under the action of the cylinder 13, the front conveyor belt 11 gradually rotates forward, and the upper openings of the front and rear conveyor belts 11 will gradually widen; when the material box 2 discharges materials, a part of the initial part of the new waterproof coiled material will be unfolded. When the new waterproof coiled material falls into the box body 3, the unfolded part of the new waterproof coiled material will automatically fall between the two groups of conveyor belts 11.

[0021] As a further solution of the present invention, the engaging mechanism includes a first slide bar 19 slidably arranged at the rear side of the frame 1. The front end of the first slide bar 19 is fixedly connected with a first clamping block 20. The upper end of the clamping block is beveled; a second spring 21 is fixedly connected to the first clamping block 20. The rear end of the second spring 21 is fixedly connected with the frame 1; a second clamping block 22 is fixedly connected to the rear side position of the box body 3. The second clamping block 22 is in clamping cooperation with the first clamping block 20; a reset mechanism is arranged on the frame 1. The reset mechanism is used to drive the first clamping block 20 and the second clamping block 22 to disengage after the box body 3 is stuck at a low position and remains for a period of time, so as to reset the box body 3; During operation, refer to Figure 5 、 Figure 9, after the conveyor belt 11 on the current side is locked, the waterproof coiled material clamped by the two groups of conveyor belts 11 is in a static state relative to the two groups of conveyor belts 11. As the frame 1 continues to move forward, the pressing roller 5 continuously presses the laid waterproof coiled material. Therefore, the waterproof coiled material will pull the overall box body 3 downward. When the box body 3 moves downward to the bottommost position, the second latch 22 on the box body 3 engages with the first latch 20 on the frame 1, and the box body 3 will remain stationary at the lowermost position.

[0022] As a further solution of the present invention, the reset mechanism includes a first driving wheel 23 rotatably connected to the left side of the box body 3, and the first driving wheel 23 is fixedly connected to the bottom shaft of the rear conveyor belt 11; a second driving wheel 24 is provided at the bottom position of the first driving wheel 23, the second driving wheel 24 is rotatably connected to the frame 1 and coaxially fixedly connected with a first pulley 25, and a belt 26 is provided on the first pulley 25; a second pulley 27 is rotatably connected to the rear side of the frame 1, and the belt 26 meshes with both the first pulley 25 and the second pulley 27; the right end of the second pulley 27 is fixedly connected with a lead screw 28, a second sliding rod 29 is sleeved on the lead screw 28 and the second sliding rod 29 is slidably connected to the frame 1, the right end of the second sliding rod 29 is fixedly connected with a first push block 30, a second push block 31 is provided on the right side of the first push block 30, and the second push block 31 is fixedly connected with the first sliding rod 19; The lead screw 28 does not have self-locking property and a third spring 32 is sleeved on the lead screw 28, and both ends of the third spring 32 are fixedly connected with the frame 1 and the second sliding rod 29 respectively; the lead screw 28 is threadedly connected with the second sliding rod 29; During operation, refer to Figures 4-6 , Figure 9 , when the box body 3 moves to the lowermost position, at this time the sensor detects that the box body 3 is at the lowest point and drives the air cylinder 13 to contract, the air cylinder 13 drives the sliding frame 12 to start rotating backward, and the front conveyor belt 11 will gradually merge with the rear conveyor belt 11; when the air cylinder 13 drives the sliding frame 12 to rotate backward to the initial position, the front and rear conveyor belts 11 will clamp the end part of the previous roll of waterproof coiled material and the initial part of the new roll of waterproof coiled material, and the two parts of the waterproof coiled material are stacked together; at this time, the two friction blocks 16 are separated from the two arc-shaped pressing plates 18, and under the action of the first spring 17, the two friction blocks 16 are separated from the turntable 15, and the two groups of conveyor belts 11 resume transmission. When the frame 1 continues to move forward, the pressing roller 5 will press the two parts of the waterproof coiled material together and lay them on the ground; Since the initial end of a new roll of waterproofing membrane needs to be pressed by the pressing roller 5 after moving a certain distance on the rack 1, the box body 3 needs to remain at the bottom position before the new roll of waterproofing membrane is pressed by the pressing roller 5 and can be reset after the new roll of waterproofing membrane is pressed by the pressing roller 5; when the box body 3 moves to the bottommost position, the first driving wheel 23 on the box body 3 will be in contact with the second driving wheel 24. When the two conveyor belts 11 resume transmission, the rear conveyor belt 11 will drive the first driving wheel 23 to rotate, the first driving wheel 23 will drive the second driving wheel 24 to rotate, the second driving wheel 24 drives the second pulley 27 to rotate through the first pulley 25 and the belt 26, the second pulley 27 drives the lead screw 28 to rotate, the lead screw 28 pushes the second sliding rod 29 to move to the right, the second sliding rod 29 drives the first push block 30 to move to the right. When the first push block 30 moves to contact with the second push block 31, it will push the second push block 31 backward, the second push block 31 drives the first clamping block 20 to move backward through the first sliding rod 19, the first clamping block 20 disengages from the second clamping block 22, and the box body 3 will automatically reset upward; during this process, the two conveyor belts 11 will transport the initial end of the new waterproofing membrane to the position of the pressing roller 5 and the initial end of the new waterproofing membrane is pressed by the pressing roller 5 and laid on the ground.
