Description

TECHNICAL FIELD

[0001] The present application relates to a kind of construction equipment in the field of building waterproof and its construction method, in particular to a kind of surface is covered with anti-sticking isolation film and is laid with the equipment of waterproof layer of coiled material, and coiled material waterproof laying method. BACKGROUND

[0002] Waterproof coiled material is mainly used for building wall below, roof, and tunnel, highway, bridge etc., to resist external rainwater, groundwater leakage, a kind of flexible building material product that can be curled into roll, it is as the leakage connection material between engineering foundation and building, is the first barrier of the entire engineering waterproof, plays a crucial role to the entire project.

[0003] Among the commonly used waterproof coiled material in building waterproof at present, a kind of waterproof coiled material with self-adhesive layer on surface and covered with anti-sticking isolation film on "adhesive layer", such as "self-adhesive waterproof coiled material", "wet-laid waterproof coiled material" etc., the waterproof construction steps of this kind of coiled material are as follows: ① coiled material unwinding on site → ② remove the anti-sticking isolation film on the surface of coiled material adhesive layer → ③ coiled material waterproof layer is laid with "self-adhesive" or "wet-laid" on waterproof base surface or according to the specific size of base surface, cut coiled material and then lay waterproof layer. However, the above construction process at present is mostly completed by manual operation, which has the defects or deficiencies of low construction efficiency, high labor intensity, high labor cost, large volume of waste anti-sticking isolation film garbage and serious environmental pollution. In addition, manual film tearing is also very easy to cause coiled material adhesive layer to be bonded together before and after, resulting in low construction efficiency and material waste.

[0004] After searching the relevant technical literature, it is found that the more relevant disclosed literature has the Chinese utility model patent "A coiled material flat laying forming machine" with the publication number CN207727862U and the publication date of August 14, 2020, and the Chinese invention patent application "A unwinding and winding machine for laying waterproof coiled material" with the publication number CN111717697A and the application publication date of August 14, 2020, although they replace manual film tearing and manual laying with mechanical construction, and both are provided with a release film recycling device, however, there are still some deficiencies and defects. First of all, during the laying of the waterproof coiled material, it is necessary to ensure that the coiled material unwinding and the release film recycling are synchronized, otherwise the release film will be pulled off during the recycling process due to the slow unwinding speed, or the coiled material will be laid with the film due to the slow recycling speed. The film collecting roller and the unwinding roller in the above-mentioned prior art both lack a synchronization device, and cannot realize the synchronization of the coiled material unwinding and the release film recycling process. For example, in the "A coiled material flat laying forming machine" of CN207727862U, a gear meshing method is used to ensure that the laying roller and the protective film winding roller rotate synchronously, but because the radius of the coiled material on the waterproof coiled material support roller and the radius of the film on the protective film winding roller change in real time during the construction operation, the linear speed of the film unwinding and the film winding changes in real time, so the synchronous rotation can only ensure that the angular velocity in the unwinding and winding process is relatively constant, and cannot ensure that the linear speed is the same. For example, in the "A unwinding and winding machine for laying waterproof coiled material" of CN111717697A, an active film collecting method of the film collecting motor is used. Therefore, the above-mentioned prior art cannot guarantee the appropriate film collecting tension, so when the film collecting linear speed is greater than the coiled material unwinding linear speed, the coiled material release film will be pulled off, and when the film collecting linear speed is less than the coiled material unwinding linear speed, the coiled material release film cannot be recycled in time, causing the coiled material to be laid with the film. Secondly, the unwinding roller in the above-mentioned prior art lacks a coiled material unwinding tension providing device, and cannot provide effective stretching tension to the unwinding coiled material, thereby causing wrinkles in the coiled material waterproof layer laying process and other defects that cannot meet the quality requirements of the waterproof layer laying.

[0005] In addition, in CN111717697A "A unwinding and winding machine for laying waterproof roll material", the unwinding roller adopts a "expansion shaft" device as the positioning and locking device of the unwinding roll material core pipe. Due to the expansion principle of the core pipe expansion shaft device (the expansion shaft is inserted into the roll material core pipe, and the expansion of the expansion shaft expansion unit causes the outer diameter of the expansion shaft to increase, thereby expanding the roll material core pipe), the outer diameter of the expansion shaft is smaller than the inner diameter of the core pipe within the range of 10mm, which is the best. When the size deviation is too large, the expansion shaft will be expanded and the core pipe will be expanded. Therefore, the use of the expansion shaft to expand the roll material core pipe will cause the expansion shaft to be unable to insert into the roll material core pipe which is deformed in appearance due to transportation and other factors, resulting in the defect that the roll material with the above-mentioned appearance deformation cannot be used by the equipment. The core pipe locking device is lacking on the film winding roller, and the roll material anti-adhesion separation film is directly wound on the film winding roller, which causes the roll material anti-adhesion separation film to be difficult to separate from the film winding roller, and seriously reduces the construction efficiency. SUMMARY

[0006] To solve the defects of the prior art, the present application provides a roll waterproof layer laying and roll material feeding integrated construction equipment, which solves the synchronization of unwinding and film winding during the laying of waterproof roll material and improves the laying quality.

The film winding motor provides a limited film winding torque for the film winding shaft through the film winding torque limiting device, thereby providing a film winding tension for the roll material anti-adhesion separation film recovery, and the film winding linear speed provided by the film winding motor to the film winding shaft is always greater than the unwinding speed. The electric control device is installed on the equipment support and contains a power supply and a control device, the electric control device being electrically connected to the film winding motor and other electric facilities.

[0010] Further, the roll core shaft pipe locking device adopts one of roll core shaft pipe locking chuck or expansion shaft locking.

[0011] When the roll core shaft pipe locking device adopts roll expansion shaft, the roll expansion shaft is coaxially fixedly installed on the unwinding shaft.

[0012] In order to conveniently lock and fix the roll on the construction site, including the roll core shaft pipe deformation, the roll core shaft pipe locking device preferably adopts roll core shaft pipe locking chuck device.

[0013] Further, the roll core shaft pipe locking device adopts one of roll core shaft pipe locking chuck or expansion shaft locking.

[0014] In order to facilitate the equipment movement and realize the unwinding and laying construction of the waterproof layer of the roll, a walking mechanism is installed below the equipment support of the present application, and the walking mechanism can be manually pushed or pulled to walk, or can be driven by power.

[0015] In order to more easily realize the installation, positioning and locking operation process of the unwinding roll on the unwinding shaft, the unwinding shaft is rotatably connected with the equipment support through a semicircular bearing, the semicircular bearing can be divided into two along the horizontal plane of the bearing axial center, and the unwinding shaft and the semicircular bearing can be quickly disassembled or assembled, the unwinding shaft is disassembled, positioned and locked with the unwinding roll, and then reinstalled on the equipment.

[0016] In order to improve the unwinding accuracy and operation efficiency of the present application, a meter counting sensor and a meter counting reading display screen are further included in the roll waterproof laying equipment provided by the present application, the meter counting sensor is installed on the equipment support, and the meter counting reading display screen is installed on the equipment support or is separately arranged outside the equipment support.

[0017] In order to reduce the energy consumption of the present application, a monitoring device for monitoring the rotation of the unwinding roll is further installed on the equipment support of the present application, the monitoring device is electrically connected with the electric control device, when the unwinding and laying operation of the roll starts, the monitoring device detects that the roll above the unwinding shaft starts to rotate with the unwinding shaft, and generates a signal to the electric control device, and then the electric control device starts the film winding motor to operate; when the unwinding roll stops working, the signal of the monitoring device stops, and the film winding motor also stops operating.

[0018] In order to further improve the cutting efficiency and cutting accuracy of the roll and ensure the flatness of the cutting edge of the roll, a roll cutting device is further included in the roll waterproof laying equipment provided by the present application, and the roll cutting device is separately arranged with the equipment support or fixedly connected with the equipment support at the discharge end of the unwinding roll.

[0019] To further ensure that the unwinding and winding processes of the roll material remain synchronized throughout the invention, the maximum unwinding torque output value T of the unwinding torque limiting device of the invention needs to be determined before manufacturing the invention. 1max The maximum film-taking torque output value T of the film-taking torque limiting device 2max The maximum film-taking speed output value S of the film-taking motor 2max The parameter values ​​are designed, and the above parameter design will serve as the basis for selecting the parameters of the film take-up motor, the unwinding torque limiting device, and the film take-up torque limiting device in the equipment.

[0020] To provide sufficient tension during the unwinding of the roll material and ensure a smooth waterproof layer, the maximum unwinding torque output value T of the unwinding torque limiting device is specified. 1max The parameter design must meet the condition that the minimum unwinding tension value that the unwinding torque limiting device can provide to the unwinding shaft should always be greater than the maximum unwinding tension value required by the waterproofing membrane itself to ensure that the waterproofing layer is laid flat and straight, that is: T 1max >F 1max * D 1max / I1, to ensure that the unwinding torque limiting device can provide sufficient unwinding tension to ensure that the waterproof layer is rolled out and laid flat. Among them, F 1max It is the maximum unrolling tension value required to ensure that the waterproof layer is laid flat and straight; D 1max I1 is the maximum unwinding radius of the roll material; I1 is the transmission ratio of the first transmission device.

[0021] To provide sufficient take-up tension and ensure that the anti-stick release film of the unwound roll can be smoothly retracted by the take-up shaft, the maximum take-up torque output value T of the take-up torque limiting device is specified. 2max The parameter design must meet the condition that the minimum film-taking tension value that the film-taking torque limiting device can provide to the film-taking shaft should always be greater than the maximum film-peeling tension value required for the anti-stick release film to peel off the roll material, that is: T 2max >F 2max * D 2max / I3, to ensure that the film winding torque limiting device can provide sufficient film winding tension to ensure that the roll unwinding and winding processes are synchronized. Among them, F 2max It is the "maximum peeling tension" required for the release liner to be peeled off the roll material; D 2max I is the maximum film-taking radius of the film-taking shaft; I3 is the transmission ratio of the third transmission device.

[0022] To ensure the timely recovery of the anti-stick release film from the unwound roll of material by the take-up shaft, and to guarantee that the unwound and anti-stick release film recovery processes remain synchronized, the maximum take-up speed output value Nmax of the take-up motor must be designed to meet the condition that the minimum take-up linear speed that the take-up motor can provide to the take-up shaft is always greater than the maximum linear speed of the unwound roll, i.e.: Nmax >S max *I2*I3 / (2D 2min *π), to ensure that the anti-stick release film can be recycled in a timely manner during the unwinding process, thereby ensuring that the unwinding and rewinding processes of the roll material remain synchronized. Among them, S max D is the maximum unwinding linear speed of the roll material; 2min I1 is the minimum film-collecting radius, i.e., the outer radius of the film-collecting mandrel tube; I2 is the transmission ratio of the second transmission device.

[0023] To prevent the roll material on the unwinding shaft from being passively rotated and unwound under the action of "film tension" during equipment operation, the maximum unwinding torque output value T is specified. 1max The parameter design must also meet the condition that the minimum unwinding tension value that the unwinding torque limiting device can provide to the unwinding shaft should always be greater than the maximum take-up tension value of the unwinding shaft, that is: T 1max >T 2max *D 1max * I3 / (D 2min *I1).

[0024] Using the above-described roll waterproofing laying and cutting equipment, the present invention provides a roll waterproofing laying and cutting method, comprising the following steps:

[0025] Preparation work for roll material laying and cutting: Install the roll material and take-up mandrel tube, and position and lock the waterproof roll material on the roll-up shaft through the roll mandrel tube locking device; position and lock the take-up mandrel tube on the take-up shaft through the take-up mandrel tube locking device. Peel off the anti-stick release film on the surface of the roll material and wrap it around and fix it on the take-up mandrel tube; turn on the power switch in the electrical control device to supply power to the various electrical devices of the equipment. At this time, the take-up motor works and drives the take-up shaft (31) to rotate, further tightening the anti-stick release film of the roll material on the take-up mandrel tube.

[0026] When laying the roll waterproofing layer, align the equipment with the base surface to be constructed, and hold the outermost end of the roll and pull it out of the equipment. One person steps on the roll that has been pulled out of the equipment to position it, while another person pulls or pushes the equipment in the opposite direction and controls its running direction through the equipment handle. At this time, the roll will be rolled up and laid on the waterproof base surface. At the same time, the film take-up shaft rotates synchronously to retract the anti-stick release film of the rolled roll.

[0027] When the equipment is pulled or pushed to begin unwinding and laying the waterproof substrate, the torque borne by the unwinding shaft gradually increases, providing unwinding tension for the roll material. When the actual torque borne by the unwinding shaft is greater than or equal to the set torque of the unwinding torque limiting device, the unwinding torque limiting device will slip. At this time, the unwinding shaft will rotate passively and begin unwinding and laying the roll material.

[0028] Wherein, when the film is wound, the film winding speed is always greater than the winding speed, so the actual film winding torque borne by the winding shaft will always be greater than or equal to the set torque of the film winding torque limiting device, that is, when the film winding shaft is winding, the film winding torque limiting device will always be in a "slip" state, thereby ensuring that the winding and film winding processes are always synchronized;

[0029] Wherein, when the pulling / pushing device is stopped, the winding shaft stops rotating, at this time, the film prevents the adhesive isolation film from being continuously tensioned by the winding shaft, when the torque borne by the winding shaft is greater than or equal to the torque set value of the film winding torque limiting device, the film winding torque limiting device will "slip", the winding shaft stops rotating, and the film winding stops;

[0030] The coiled material is discharged: the coiled material is discharged at irregular shaped base surfaces (such as floor base pits, foundation beams, roof high-low spans and other structural parts) or vertical surfaces (basement vertical walls, roof main vertical surfaces, roof parapets and other structural parts) which are not suitable for directly winding and laying by the device, the wheels below the device support are locked to prevent the device from moving, one end of the coiled material is held and pulled out of the device to the required length of the waterproof base surface, in the process, the coiled material prevents the adhesive isolation film from being synchronously recovered, the coiled material is cut to the required length of the material, and the coiled material discharge process is completed.

[0031] The beneficial effects of the present application are:

[0032] 1. The winding shaft of the present application is provided with a coiled material winding torque limiting device, the winding torque limiting device provides a braking torque to the winding shaft, thereby providing the necessary winding tension to straighten the coiled material, ensuring the smooth laying of the waterproof layer, and overcoming the defect that the existing technology lacks tension winding, which causes the waterproof layer to wrinkle during laying.

[0033] 2. The winding shaft of the present application is provided with a film winding torque limiting device, the film winding motor provides a maximum film winding limiting torque to the winding shaft through the film winding torque limiting device to drive the winding shaft to wind the film, the film winding speed provided by the film winding motor to the winding shaft is always greater than the winding speed, when the torque borne by the winding shaft is greater than or equal to the limiting output torque of the film winding torque limiting device, the film winding torque limiting device will "slip" inside, ensuring that the winding and film winding processes are synchronized, and overcoming the defect that the existing technology lacks a necessary tension control device for coiled material winding on the winding shaft, when the film winding speed is greater than the winding speed, the coiled material prevents the adhesive isolation film from being pulled apart, which causes the film winding to stop;

[0034] 3. The winding shaft of the present application adopts a winding core shaft pipe locking device, which facilitates the clamping and fixing operation of the coiled material with deformed core shaft pipe on site, and overcomes the defect that the existing "expanding shaft" cannot be inserted into the coiled material core shaft pipe which is deformed due to transportation and other factors, so that the coiled material with the above-mentioned appearance deformation cannot be used by the device.

[0035] 4. The present invention provides a film take-up mandrel locking device on the film take-up shaft. The film take-up mandrel is locked and fixed on the film take-up mandrel locking device. The roll anti-stick release film is taken back onto the film take-up mandrel, which makes it more convenient and faster to realize the roll change operation of the rolled anti-stick release film that has been taken back. It overcomes the defects of the prior art that the roll anti-stick release film is directly wound on the film take-up shaft, which makes it difficult to separate the rolled anti-stick release film from the film take-up shaft after it has been taken back, thus reducing the efficiency.

[0036] 5. This invention has the advantages of simple structure, smaller size, lighter weight, and easy portability. It also realizes the integrated operation of equipment for unrolling, retracting, laying, and cutting of waterproof membrane. It not only realizes the construction operation of laying waterproof membrane on large areas of flat surface, but also realizes the use of membrane cutting machine on base surfaces that are not suitable for direct membrane laying by equipment (such as vertical or structurally complex base surfaces), and has extremely strong construction adaptability.

[0037] 6. This invention significantly improves the efficiency of waterproofing installation and reduces the labor intensity of construction workers. It not only enables timely recycling of the anti-stick release film of the rolled material, avoiding environmental pollution caused by the waste anti-stick release film, but also prevents secondary pollution of slurry during the anti-stick release film recycling process. This provides the necessary conditions for the recycling of the anti-stick release film to be reused rationally, and achieves a high degree of environmental friendliness. Attached image description:

[0054] For the convenience of equipment movement, a walking mechanism can also be installed on the equipment, and the walking mechanism is composed of one or more wheels 11 installed below the equipment support 10.

[0055] Embodiment one:

[0056] As shown in Figure 4 , Figure 5 , Figure 6 , the embodiment discloses a roll waterproof laying equipment, which comprises an equipment support 10, a walking mechanism, a first semicircular bearing 201, a second semicircular bearing 202, an unwinding shaft 21, a first roll core tube locking chuck 221, a second roll core tube locking chuck 222, a first gear 241, a second gear 242, a magnetic powder brake 231, a roll guide roller 26, a first bearing 301, a second bearing 302, a film winding shaft 31, a first film winding core tube locking chuck 321, a second film winding core tube locking chuck 322, a magnetic powder clutch 331, a film winding motor 34, a second transmission device 35, a third transmission device 36, a film winding guide roller 38 and an electric control device 40.

[0057] The walking mechanism of the embodiment is composed of four wheels 11, which are installed below the four corners of the equipment support 10.

[0059] In the embodiment, the roll core shaft pipe locking device is composed of a first roll core shaft pipe locking chuck 221 and a second roll core shaft pipe locking chuck 222. The first roll core shaft pipe locking chuck 221 and the second roll core shaft pipe locking chuck 222 are designed as conical surfaces and are provided with a central hole and are symmetrically sleeved on the unwinding shaft 21. The first roll core shaft pipe locking chuck 221 is fixedly connected with the unwinding shaft 21, or the first roll core shaft pipe locking chuck 221 is provided with a locking unit, and the locking unit and the unwinding shaft 21 form a locking fixed connection.

Thus, the film winding shaft 31 transmits torque to the film winding mandrel pipe through the first film winding mandrel pipe locking chuck 321 fixedly connected with the film winding shaft 31, thereby transmitting the required film winding tension for recovering the coiled material waterproof separating film. It should be noted that the preferred scheme is that the locking unit is additionally arranged in the second film winding mandrel pipe locking chuck 322, and the locking unit can form a locking fixed connection with the film winding shaft 31.

The selected parameter of the torque is 6Nm (the output torque of the magnetic powder clutch 331 can be adjusted at 0-6Nm, and the torque output value of the magnetic powder clutch 331 can be adjusted and set according to different working conditions on site).

[0068] 2, In order to ensure that the coiled material unwinding of the application has sufficient unwinding tension and the coiled material unwinding and take-up are synchronous, the maximum unwinding torque output value T 1max of the unwinding torque limiting device should meet the design conditions of T 1max > F 1max * D 1max / I1, and T 1max > T 2max *D 1max *I3 / (D 2min * I1).

At this time, the winding motor (34) works and drives the winding shaft (31) to rotate to wind the waterproof roll material on the winding core tube (310); Roll laying method: align the equipment on the base surface to be constructed, and pull out the outermost end of the roll material out of the equipment by hand. One person positions on the roll material that has been pulled out of the equipment, and the other person pulls or pushes the equipment in the opposite direction and controls the running direction through the equipment handle. At this time, the roll material is unwound and laid on the waterproof base surface, and the winding shaft rotates synchronously to recover the waterproof roll material. When the equipment is pulled or pushed to start unwinding and laying on the waterproof base surface, the torque borne by the unwinding shaft (21) gradually increases to provide unwinding tension for the roll material. When the actual torque borne by the unwinding shaft (21) is greater than or equal to the set torque of the unwinding torque limiting device (23), the unwinding torque limiting device (23) will slip, and the unwinding shaft (21) will rotate passively and start to unwind and lay the roll material.
