Description

Technical Field

[0001] The invention belongs to the technical field of paving machines, and in particular relates to a waterproof coiled material laying device for waterproof construction projects. Background Art

[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to prevent external rainwater and groundwater leakage. As a leak-proof connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. It is usually laid using a waterproof building paving machine.

[0003] For example, a waterproof roll material laying device disclosed in national patent publication number CN116290820B includes a laying device body, which includes a base plate, a cutting component, an offset component, a stacking mechanism and a bonding mechanism. The first bracket, the second bracket, the third bracket and the fourth bracket are installed in sequence on the top of the side of the base plate. The top of the first bracket is installed with a roll guide roller, and the surface of the roll guide roller is wound with the first waterproof roll film or the second waterproof roll film. The top of the second bracket is installed with a cutting component. The waterproof roll material laying device is provided with a cutting component on the base plate, which can cut a single roll film and cut the roll film into the required width according to the specific laying situation to avoid waste. The operation is simple and efficient. During laying, the gap where the first waterproof roll film and the second waterproof roll film are bonded can be provided with another layer of independent waterproof roll film to seal it, further improving the waterproof and anti-warping capabilities.

[0004] However, the conventional device still has the following problems when in use:

[0033] When the present invention needs to load materials, the waterproof coiled material 11 is placed in front of the vehicle frame 1, and the bidirectional running motor 19 is started to rotate the adjusting gear 1 20. The meshing of the adjusting gear 1 20 and the adjusting gear 2 21 drives the retaining plate 4 to deflect with the laying roller 1 2 as the axis and extend to the front position of the vehicle frame 1. At this time, the staff rolls the waterproof coiled material 11 to roll the winding rods 10 at both ends into the clamping assembly. The second clamping hoop 6 in the clamping assembly is slidably connected to the first clamping hoop 5 through the protruding block and the connecting channel 8, and the elastic positioning is achieved by setting the pressure of the connecting channel 8. By adjusting the position of the second clamping hoop 6 and arranging the second clamping hoop 6 side by side, the rolling retaining plate 4 is maintained. The winding rod 10 is fitted with the first clamping hoop 5 and the second clamping hoop 6, and then the position of the second clamping hoop 6 is restored so that the opening angle of the first clamping hoop 5 and the second clamping hoop 6 is less than 90°. Then the two-way operation motor 19 is started to reverse and the retaining plate 4 is turned from a horizontal state to a vertical state to complete the installation and replacement of the waterproof membrane 11. The ends of the waterproof membrane 11 are sequentially placed on the long tightening frame 29, and the asphalt layer of the waterproof membrane 11 is heated by the ignition end 35. Then, the membrane is rolled into the laying roller 2 30 and the laying roller 1 2 to achieve fitting to the ground. This device can achieve independent loading and replenishing of materials by one staff member without the need for manual handling, which reduces manpower consumption and is convenient and fast.

[0034] Embodiment 2, on the basis of embodiment 1, the outer walls of both sides of the laying roller 2 are fixedly sleeved with a hinge shaft 12, the outer wall of the hinge shaft 12 is fixedly connected with a connecting plate 13, the outer wall of the connecting plate 13 is rotatably connected with a roller wheel 14, the outer wall of the roller wheel 14 is movably fitted with the outer wall of the waterproof membrane 11, the outer walls of the connecting plates 13 on both sides are fixedly connected with the same tension spring 38, the outer walls of both sides of the laying roller 2 are fixedly connected with a turntable 15, the outer walls of both sides of the roller wheel 14 are fixedly connected with a turntable 2 17 through the connecting plate 13, and the outer walls of the turntable 2 17 and the turntable 1 15 are rotatably engaged with the same rotating belt 16.

[0035] In the present invention, the elastic tightening of the tension spring 38 enables the two roller wheels 14 to always press the waterproof membranes 11 of different circumferences. When the present invention is in the mobile laying state, the laying roller wheel 2 rolls on the ground, and the rotating belt 16 synchronously drives the roller wheel 14 to rotate. Since the friction of the waterproof membrane 11 is high, it intersects with the direct pulling of the traditional paving machine. The present invention relatively alleviates the pulling pressure of the device, reduces the friction by kinetic energy, and further reduces the consumption of manpower. It should be emphasized that in the present invention,

[0036] Example three, based on Example two, the outer wall of one side of the turntable 2 17 away from the roller wheel 14 is fixedly connected to the limiting gear 18, the outer wall of one side of the second clamping hoop 6 is fixedly connected to the limiting gear 2 23, the outer wall of the limiting gear 18 is meshed with the outer wall of the limiting gear 2 23, and a placement channel 22 is opened on the outer wall of one side of the retaining plate 4.

[0037] When the waterproofing membrane 11 is gradually consumed as it is laid, the circumference of the waterproofing membrane 11 will gradually decrease, and the two relative roller wheels 14 will get closer and closer to the retaining winding rod 10 as the limit gear 2 is tightened. At the same time, the limit gear 1 18 will synchronously press against the outer wall of the second clamping hoop 6 and engage with the limit gear 23. The short engagement movement distance is sufficient to ensure that the second clamping hoop 6 can synchronously rotate half a circle until it is side by side with the first clamping hoop 5. At this time, the clamping assembly automatically releases the clamping of the used retaining winding rod 10, which is convenient for the staff to change materials. When the staff replaces a new roll of waterproofing membrane 11, the outer wall of the waterproofing membrane 11 presses against the two roller wheels 14 to reopen the connecting plate 13. At this time, the limit gear 1 18 will disengage from the engagement with the limit gear 2 23, and the second clamping hoop 6 loses the pressure and rebounds again, thereby clamping the outer wall of the retaining winding rod 10, completing the replacement.

[0038] Embodiment 4, on the basis of embodiment 3, is characterized in that a support block 24 is movably connected to the outer wall of the shaft of the roller wheel 14, and the outer walls of one side of the two support blocks 24 are movably fitted with each other, and a groove 25 is provided on the outer wall of one side of the support block 24, and a hinge 26 is fixedly installed on the inner wall of one side of the groove 25, and a baffle 1 27 is fixedly connected to the outer wall of one side of the hinge 26, and the outer wall of baffle 1 27 is movably fitted with the inner wall of the groove 25, and a baffle 2 28 is fixedly connected to the outer wall of one end of the hinge 26 away from the baffle 2 28, and the baffle 2 28 is 135° with the baffle 1 27, and the baffle 2 28 at the position of the two support blocks 24 can movably fit with each other.

[0039] When the waterproof roll 11 is consumed, the two roller wheels 14 are close to each other. At this time, the two inclined connecting plates 13 are pressed against each other and then merged and fitted together. After being pressed, the baffle 28 lifts the baffle 1 27 through the hinge 26. The lifted baffle 1 27 will lift the retaining roll rod 10, and apply external force to the retaining roll rod 10 to squeeze it out between the first clamping hoop 5 and the second clamping hoop 6, which is convenient for replacement.

[0040] The working principle and use process of the present invention: When the present invention needs to be loaded, the waterproof coiled material 11 is placed in front of the vehicle frame 1, and the bidirectional operation motor 19 is started to rotate the adjusting gear 1 20. The meshing of the adjusting gear 1 20 and the adjusting gear 2 21 drives the retaining plate 4 to deflect with the laying roller 1 2 as the axis and extend to the front position of the vehicle frame 1. At this time, the staff rolls the waterproof coiled material 11 to roll the two ends of the retaining roller 10 into the clamping assembly. The second clamping hoop 6 in the clamping assembly is slidably connected to the first clamping hoop 5 through the protruding block and the connecting channel 8, and the elastic positioning is achieved by setting the pressure of the connecting channel 8. By adjusting the position of the second clamping hoop 6 and arranging the second clamping hoop 6 side by side, the rolling retaining roller 10 is kept in contact with the first clamping hoop. The hoop 5 and the second clamping hoop 6 are fitted together, and then the position of the second clamping hoop 6 is restored so that the opening angle of the first clamping hoop 5 and the second clamping hoop 6 is less than 90 degrees, and then the two-way operation motor 19 is started to reverse, and the holding plate 4 is turned from the horizontal state to the vertical state, thereby completing the installation and replacement of the waterproof membrane 11. The ends of the waterproof membrane 11 are sequentially leaned on the long tightening frame 29, and the asphalt layer of the waterproof membrane 11 is heated by the ignition end 35 spraying fire, and then rolled into the laying roller 2 30 and the laying roller 1 2 to achieve fitting to the ground. This device can achieve independent loading and replenishing of materials by one staff member, and no manual handling is required, which reduces manpower consumption and is convenient and fast. In the present invention, the elastic tightening of the tension spring 38 enables the two roller wheels 14 to always be pressed against the ground. For waterproofing membrane 11 with the same circumference size, when the present invention is in the moving laying state, the laying roller 2 rolls on the ground, and will synchronously drive the roller wheel 14 to rotate through the rotating belt 16. Since the friction of the waterproofing membrane 11 is relatively high, compared with the direct pulling of the traditional paving machine, the present invention relatively alleviates the pulling pressure of the device, reduces the friction by kinetic energy, and further reduces the consumption of manpower. When the waterproofing membrane 11 is gradually consumed as it is laid, the circumference size of the waterproofing membrane 11 will gradually decrease, and the two relative roller wheels 14 will get closer and closer to the holding reel rod 10 as the tension spring 38 is tightened. At the same time, the limit gear 18 will synchronously press against the outer wall of the second clamping hoop 6 and engage with the limit gear 2 23. The short engagement movement distance is enough It is enough to ensure that the second clamping hoop 6 can rotate half a circle synchronously until it is side by side with the first clamping hoop 5. At this time, the clamping assembly automatically releases the clamping of the used holding roll rod 10, which is convenient for the staff to change materials. When the staff replaces a new roll of waterproof membrane 11, the outer wall of the waterproof membrane 11 presses against the two roller wheels 14 to reopen the connecting plate 13. At this time, the limit gear 18 will be disengaged from the engagement with the limit gear 2 23, and the second clamping hoop 6 loses the pressure and rebounds again, thereby clamping the outer wall of the holding roll rod 10 to complete the replacement. When the waterproof membrane 11 is consumed, the two roller wheels 14 are close to each other. At this time, the two inclined connecting plates 13 press against each other and then merge and fit together. After being pressed, the baffle 2 28 lifts the baffle 1 27 through the hinge 26.The raised baffle 1 27 will lift the retaining rod 10, and apply external force to squeeze the retaining rod 10 between the first clamping hoop 5 and the second clamping hoop 6, making replacement easier.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
