Description

Technical Field

[0001] The invention relates to a coiled waterproof layer construction device in the field of building waterproofing, in particular to a slurry discharge device for wet laying operation of a waterproof layer. Background Art

[0002] Waterproof membrane is mainly used under building walls, roofs, tunnels, roads, bridges, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rain and groundwater. As a leak-proof connection material 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.

[0003] The commonly used waterproofing membranes in building waterproofing include a type of wet-laid waterproofing membrane with a self-adhesive layer on the surface. During the construction of this type of wet-laid membrane waterproofing layer, it is necessary to evenly discharge the excess wet-laid slurry between the waterproof layer and the base surface outside the waterproof layer, and it is necessary to discharge the air mixed between the waterproof layer and the base surface when the waterproof layer is laid, so as to form a sealed interface between the wet-laid waterproof layer and the base surface without water leakage. However, the current wet-laid membrane waterproofing layer generally adopts the manual slurry discharge operation method, which has the defects of high labor intensity and low personnel efficiency. In addition, manual slurry discharge is prone to uneven and continuous discharge of wet-laid slurry, and the air mixed in the waterproof layer during the laying process cannot be completely discharged, which affects the sealing and waterproofing effect of the wet-laid waterproof layer and is prone to the risk of large-scale water leakage in the waterproof layer.

[0004] After searching, the Chinese utility model patent "A roll material flat-laying forming machine" with the announcement number CN207727862U described a waterproof layer compacting and slurry discharge device composed of a downward pressing roller (6), that is, the compaction and slurry discharge of the wet-laid waterproof layer are completed by rolling the waterproof layer with a roller. However, this rolling method of compacting and slurry discharge of the wet-laid waterproof layer cannot achieve the operation process of uniformly discharging the wet-laid slurry from the waterproof layer, especially for the slurry discharge operation process of the roll material waterproof layer with a high consistency wet-laid slurry or a base surface with poor flatness.

[0005] The Chinese utility model patent with the announcement number CN212583292U discloses a waterproofing coiled material laying device, wherein a frame is connected to a scraping device along the laying direction thereof through a connecting plate, the scraping device comprises a motor, a threaded rod, a guide rod and a scraper for contacting the waterproofing coiled material, the motor is mounted on the connecting plate, a support plate is arranged on the connecting plate, the two ends of the threaded rod are respectively connected to the driving end of the motor and the support plate, one end of the guide rod is fixed to the support plate, the threaded rod and the guide rod are both arranged parallel to the rotating roller, the threaded rod passes through the scraper and is threadedly connected to the scraper, and the guide rod passes through the scraper and is slidably connected to the scraper. The patent utilizes a motor to drive the threaded rod to rotate, thereby driving the scraper to reciprocate along the length direction of the guide rod to horizontally scrape the laid waterproofing coiled material, however, the above-mentioned slurry discharge device for scraping the laid waterproofing coiled material by horizontally reciprocating motion of the scraper is not only complex in structure, but also has low operating efficiency. In addition, since the patent adopts a reciprocating motion scraping operation, when the waterproof layer is wet-laid, the wet-laid slurry between the waterproof layer and the base surface will overflow on both sides of the scraper during the lateral translation of the scraper. This will affect the slurry discharge and exhaust effect of the wet-laid waterproof layer, and further lead to large-scale water leakage in the wet-laid waterproof layer. Therefore, this existing technology is not suitable for wet-laid roll material discharge construction. Summary of the invention

[0006] The purpose of the present invention is to provide a wet-laid coiled waterproof layer compaction and slurry discharge device, which can effectively discharge the excess wet-laid slurry between the waterproof layer and the base surface and the air entrained in the paving process of the waterproof layer, thereby improving the sealing and waterproofing effect of the wet-laid waterproof layer.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The present invention provides a wet-laid coiled material waterproof layer compaction and slurry discharge device, which comprises an equipment bracket, and a traveling mechanism and a slurry discharge mechanism installed on the equipment bracket.

[0009] The traveling mechanism includes one or more wheels installed under the equipment support, or the traveling mechanism also includes a power drive system installed on the equipment support, wherein the drive system includes a power and drive control device and a drive device, the power and drive control device is fixedly installed on the equipment support, the power and drive control device is equipped with a power source and a drive control device, provides power and power output control for the drive device, and the drive device drives one or more wheels to operate. The traveling mechanism of the present invention can be pushed or pulled manually, or can be driven by power.

[0010] The slurry discharge mechanism includes a first connecting rod, a flexible scraper and a scraper support frame, and the flexible scraper is a single straight scraper. The first connecting rod is vertically installed on the equipment bracket, and the connection between the first connecting rod and the equipment bracket is a fixed connection or a sliding connection, a rotating connection, or both. The scraper support frame is fixedly installed on the flexible scraper, the upper part of the flexible scraper is fixed in the scraper support frame, and the lower part of the flexible scraper is exposed outside the lower end edge of the scraper support frame and contacts the base waterproof layer. The scraper support frame provides the necessary support rigidity for the flexible scraper to ensure that the slurry discharge pressure of the flexible scraper on the surface of the roll waterproof layer is uniform. The flexible scraper is hinged to the lower end of the first connecting rod through the scraper support frame, and the left and right ends of the flexible scraper can freely rotate up and down at a certain angle along its "hinge" to ensure that the left and right sides of the flexible scraper are in close contact with the upper surface of the roll waterproof layer. The flexible scraper is inclined at an angle of 0-±45 degrees in the horizontal direction perpendicular to the running direction of the equipment. When the absolute value of the installation inclination angle of the flexible scraper is greater than 0°, the wet slurry of the waterproof layer will be discharged more along the inclination direction of the flexible scraper. The greater the absolute value of the inclination angle, the more wet slurry will be discharged along the inclination direction of the flexible scraper, so as to achieve the effect that the wet slurry can be discharged more concentratedly from one side of the waterproof layer and avoid more wet slurry from contaminating the waterproof layer, thereby achieving the purpose of reducing the waste of wet slurry. The horizontal projection length of the flexible scraper and the equipment in the operating direction is approximately equal to the width of the coil, so as to ensure that the wet slurry under each coil waterproof layer is evenly discharged by the flexible scraper.

[0011] In order to obtain a relatively more stable slurry discharge pressure, a first elastic component is also provided on the slurry discharge mechanism, and the connection form between the first connecting rod and the equipment bracket adopts one of a sliding connection form or a rotating and sliding connection form, and the first elastic component is connected to the equipment bracket and the first connecting rod respectively. At this time, the slurry discharge pressure of the flexible scraper is generated by compressing or stretching the first elastic component and generating elastic force, and this "elastic force" acts downward on the first connecting rod, and then is transmitted to the flexible scraper by the first connecting rod, thereby generating slurry discharge pressure on the waterproof layer. The elastic force of the first elastic structure can enable the flexible scraper to obtain a relatively more stable slurry discharge pressure value.

[0012] In order to enable the equipment to achieve the purpose of reciprocating bidirectional slurry discharge on the waterproof layer during the slurry discharge operation, the connection form between the first connecting rod and the equipment bracket adopts a rotating connection, and the flexible scraper can be in the horizontal inclination angle between 0-±45° and the vertical direction of the equipment operation, and the positive and negative inclination angles can be switched at any time, thereby achieving the purpose of reciprocating bidirectional slurry discharge of the equipment. At the same time, in order to prevent the flexible scraper from rotating during the slurry discharge of the equipment and affecting the normal slurry discharge operation, a positioning component is provided on the equipment bracket, one end of the positioning component is connected to the equipment bracket, and the other end of the positioning component is connected to the scraper connecting rod or the scraper support frame. Through the positioning component, the flexible scraper can be in the horizontal direction perpendicular to the equipment running direction at an inclination angle that meets the operation requirements and can limit the rotation of the scraper connecting rod during the slurry discharge operation of the equipment.

[0013] In order to provide the equipment of the present invention with slurry discharge pressure more simply and conveniently, and to adjust the running direction of the equipment at any time during the slurry discharge process, an equipment handrail is fixedly installed at the front or rear end of the equipment bracket. The equipment handrail is applied with force in the vertical direction by manpower, and this force will be transmitted to the flexible scraper through the equipment bracket and the first connecting rod to generate slurry discharge pressure. Then, the magnitude of the vertical force applied to the equipment handrail is changed by manpower, thereby changing the slurry discharge pressure value of the flexible scraper on the waterproof layer. The running direction of the equipment is adjusted and changed by manpower by changing the difference in the horizontal push / pull force value on the left and right sides of the equipment handrail to ensure that the flexible scraper is always aligned with the waterproof roll below when the equipment is in operation.

[0014] In order to further save manpower, a force-applying component and a steering mechanism are added to the equipment bracket. The force-applying component is hinged or fixedly connected to the equipment bracket and the first elastic member, respectively. The force-applying component applies force to the first elastic member, causing the first elastic member to deform and generate elastic force. This elastic force is then transmitted to the flexible scraper through the first connecting rod, and the flexible scraper obtains the slurry discharge pressure. The steering mechanism can realize the adjustment or steering function of the running direction of the equipment through human driving operation or remote control of the steering mechanism.

[0015] In order to prevent the overlapping edge of the waterproofing layer of the coiled material from being contaminated by the wet slurry during the slurry discharge process and to achieve a direct bonding effect between the upper surface adhesive layer of the coiled material and the lower surface adhesive layer of the coiled material at the overlapping edge of the waterproofing layer of the coiled material, an overlapping edge pressing mechanism is also vertically installed on one or both sides of the equipment bracket in front of the slurry discharge mechanism. The overlapping edge pressing mechanism is composed of a second scraper connecting rod, an overlapping edge pressing component and a second elastic component. The upper end of the second elastic component is hinged or fixedly connected to the equipment bracket, the upper end of the second scraper connecting rod (41) is hinged or fixedly connected to the lower end of the second elastic component, the overlapping edge pressing component is hinged or fixedly connected to the lower end of the second scraper connecting rod, and the overlapping edge pressing component can be a roller or a flexible scraper. When the equipment is operating, the roller or flexible scraper contacts the overlapping edge of the rolled waterproof layer. At this time, the second elastic component applies elastic force downward to the second scraper connecting rod. This elastic force is transmitted to the overlapping edge pressing component via the second scraper connecting rod, thereby generating a rolling material overlapping edge pressing force.

[0016] The invention is beneficial in that:

[0017] The present invention adopts a flexible scraper to replace the roller-pressing slurry discharge method. Compared with the prior art that mostly uses roller-pressing to compact and discharge the waterproof layer, the adaptability to the change of the consistency of the wet slurry and the slurry discharge efficiency can be greatly improved. When the equipment is discharging slurry, the flexible scraper placed on the base waterproof layer will produce different degrees of deformation according to the change of the flatness of the base layer under the action of the slurry discharge pressure, so that the flexible scraper and the base waterproof layer form a better fit. Under the horizontal pushing and pressing action of the slurry discharge flexible scraper on the surface of the base waterproof layer, the excess wet slurry under the waterproof layer is evenly pushed forward in the slurry discharge direction and finally discharged out of the waterproof layer. At the same time, the air between the waterproof layer and the base surface is discharged together with the slurry, thereby greatly improving the sealing and waterproofing effect of the waterproof layer. The flexible scraper is designed to have a horizontal inclination of 0-±45 degrees perpendicular to the running direction of the equipment. When the absolute value of the installation inclination of the flexible scraper is greater than 0°, the wet-laid slurry will be discharged relatively concentratedly along the inclination direction of the flexible scraper, which can reduce the waste of wet-laid slurry and reduce the pollution of the slurry to the waterproof layer. The flexible scraper has the function of switching between positive and negative inclinations at any time between 0-±45° and the horizontal inclination of the equipment operation direction, which can realize reciprocating two-way slurry discharge during equipment operation, thereby greatly improving the equipment operation efficiency. By adding an overlapping edge pressing mechanism to the equipment, the two operation steps of the slurry discharge and overlapping edge sealing and pressing process of the wet-laid slurry of the waterproof layer are completed at one time. Compared with the manual slurry discharge method and the prior art, the present invention greatly reduces the labor intensity of personnel, improves labor efficiency, greatly improves the stability and waterproof safety of the wet-laid waterproof layer slurry discharge operation process, and also realizes the characteristics of simple equipment structure, compactness, lightness, and easy operation.

[0048] Among them, the running mechanism structure and connection form described in this embodiment are the same as the relevant contents of "Example 1", and will not be repeated here.

The first drive wheel 111, the second drive wheel 112 and the wheel 11 are respectively arranged at the four corners below the equipment bracket 10, wherein the first drive wheel 111 and the second drive wheel 112 are equipped with a hub motor. The power and drive control device 12 is equipped with a power supply and a power output control device, and the drive device is composed of hub motors respectively built into the first drive wheel 111 and the second drive wheel 112. The power built into the power and drive control device 12 drives the hub motors respectively built into the first drive wheel 111 and the second drive wheel 112 to operate, thereby driving the equipment to travel. The power and drive control device 12 is electrically connected to the hub motors built into the first drive wheel 111 and the second drive wheel 112, respectively, thereby driving the first drive wheel 111 and the second drive wheel 112 to operate. The running direction of the equipment is adjusted by the rotation speed difference generated by the current difference input to the first driving wheel 111 and the second driving wheel 112 to achieve the adjustment and steering function of the running direction of the equipment.

[0057] The steering mechanism 14 includes a steering remote control receiving device and a steering control device. The power supply built into the power and drive control device 12 is electrically connected to the steering control device and the wheel hub motors placed in the first drive wheel 111 and the second drive wheel 112. The steering remote control receiving device can receive the device steering signal sent by the steering remote control, which is processed by the steering control device and outputs different driving currents to the wheel hub motors placed in the first drive wheel 111 and the second drive wheel 112, respectively, so that the first drive wheel 111 and the second drive wheel 112 have a speed difference, thereby realizing the adjustment of the running direction of the device and the steering function. It should be noted that the steering mechanism 14 here can also be composed of a traditional steering wheel steering gear and a differential drive axle. The steering mechanism composed of a differential drive axle and a traditional steering wheel steering gear is a prior art and will not be repeated here.

[0058] The pulp discharge mechanism described in this embodiment includes a first connecting rod 21, a flexible scraper 22, a scraper support frame 221, a first elastic member 23, a positioning assembly, and a force application assembly.

[0059] The first connecting rod 21 and the device bracket 10 are connected in a rotating and sliding manner. The first connecting rod 21 can freely slide up and down and rotate relative to the device bracket 10.

[0060] The first connecting rod 21 is vertically mounted on the equipment support 10 and is rotationally and slidably connected to the equipment support 10 . The first connecting rod 21 can freely rotate relative to the equipment support 10 and freely slide up and down.

[0061] The structure and connection form of the flexible scraper 22 are the same as those of the “third embodiment” and will not be described again here.

[0062] The force-applying assembly described in this embodiment is composed of a spiral lifter 26, a motor 261, and a lifting screw 262. The spiral lifter 26 is fixedly connected to the equipment bracket 10, and the motor 261 is transmission-connected to the power input end of the spiral lifter 26. The first elastic member 23 is mounted on the first connecting rod 21, the lower end of the first elastic member 23 is hinged to the first connecting rod 21, and the upper end of the first elastic member 23 is fixedly connected to the lifting screw 262. The motor 261 is powered on and rotated to drive the lifting screw 262 of the spiral lifter 26 to descend or ascend. When the lifting screw 262 descends, the first elastic member 23 will be compressed to generate elastic force, which is then transmitted to the flexible scraper 22 via the first connecting rod 21, and finally forms the slurry discharge pressure. Among them, the force-applying assembly can also be composed of a structural form of a slider and slideway assembly with a self-locking function, a pneumatic cylinder or a hydraulic cylinder assembly.

[0063] The positioning assembly described in this embodiment is composed of a positioning rod 25, a second positioning pin 251, and a third positioning pin 252. Circular through holes are respectively provided on both sides of the positioning rod 25. The second positioning pin 251 is fixedly set on the equipment bracket 10, and the third positioning pin 252 is fixedly set on the upper end face of the scraper support frame 221. The second positioning pin 251 and the third positioning pin 252 are respectively inserted into the circular through holes on both sides of the positioning rod 25. At this time, under the joint action of the positioning rod 26 and the positioning pins 251 / 252, the flexible scraper 22 under the first connecting rod 21 is positioned at a certain inclination angle between 0-±45° in the horizontal direction perpendicular to the running direction of the equipment, thereby indirectly limiting the rotation of the first connecting rod 21 when the equipment is discharging slurry. When a circular through hole is provided at each end of the positioning rod 25, the inclination angle is fixed and cannot be adjusted. When at least one end of the positioning rod is provided with a plurality of circular through holes, the distance between the second positioning pin (251) and the third positioning pin (252) is adjusted by inserting the positioning pins into different through holes, so that the flexible scraper (22) is in a horizontal direction perpendicular to the running direction of the equipment at different inclination angles that meet the operation requirements.
