Description

Technical Field

[0001] The invention relates to the technical field of waterproof material transportation, in particular to a storage and handling device for waterproof materials on the top floor of a building construction. Background Art

[0002] In building construction, the top layer and waterproof materials have a close and critical relationship. The selection of waterproof materials must match the design and materials of the top layer to ensure a good waterproof effect. For example, different types of roofs, such as flat roofs, pitched roofs or green roofs, have different requirements for waterproof materials. Appropriate waterproof materials need to be selected according to the characteristics of the top layer. Waterproof materials are mainly divided into roll materials, waterproof coatings, sealing materials and rigid waterproof materials. Roll materials include asphalt waterproof roll materials and polymer waterproof roll materials, which are suitable for waterproofing roofs and underground projects.

[0003] The waterproof roll is easily squeezed and deformed during transportation or storage, which affects its flatness after unfolding. A storage device for waterproof roll during transportation is disclosed in the Chinese patent application publication specification CN207791504U. A piston rod can be inserted into the paper tube inside the waterproof roll from below, and a fixing rod can be inserted into the paper tube inside the waterproof roll from above, so that the waterproof roll is fixed, and the fixing effect is better. During transportation, the waterproof roll will not roll over due to bumps, and there is a certain distance between the waterproof rolls so that they will not stick to each other. In addition, the bottom plate can be rotated relative to the base, which is convenient for taking the waterproof roll. When taking it, the air is released from the valve on the No. 1 pipe, and the piston rod enters the piston cylinder due to gravity, raising the telescopic rod, and the piston rod and the fixing rod are separated from the paper tube. The waterproof roll is easy to fix and take, and the structure is simple and easy to use.

[0004] The above patent uses the design of the piston rod and the fixing rod to provide a good fixing effect when the coil is placed vertically, preventing the coil from rolling or tipping over during transportation. In actual applications, it is found that there is a certain gap between the piston rod and the fixing rod and the coil. As the coil sways in the gap, its weight may be unevenly concentrated at a certain point at the bottom, causing the bottom edge of the coil to bear excessive local pressure, increasing the risk of damage. In addition, in the above patent, when taking out the waterproof coil, it is necessary to dump the waterproof coil first, and then two staff members will move it away. In this process, the weight of the waterproof coil is concentrated on the bottom edge of the waterproof coil, and the pressure on the bottom edge of the waterproof coil is too high, so the bottom edge of the waterproof coil is easily damaged. To this end, we provide a storage and handling device for top waterproof materials in construction to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide a storage and handling and conveying device for top-layer waterproof materials in building construction. The device can fix the waterproof membrane from the inside while adjusting it to a vertical state, and can also prevent the weight of the waterproof membrane from being concentrated on its bottom edge when it is taken out, causing the bottom edge of the waterproof membrane to be easily damaged.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a storage and handling and conveying device for top waterproofing materials in building construction, comprising a box body, the box body comprising a storage box, a rotating fixing mechanism is arranged in the storage box, and a limiting mechanism for limiting the rotating fixing mechanism is also arranged in the storage box.

[0007] The rotating fixing mechanism includes a fixing seat fixed to the inner bottom wall of the storage box, the fixing seat is rotatably connected with a rotating shaft, a support rod is fixed to one end of the rotating shaft, a gear is fixed to the other end of the rotating shaft, a fixing plate is fixed to the side of the support rod, an airbag is fixed to the fixing plate, a mounting frame slidably connected to the side of the support rod is fixed to the other side of the airbag, a toothed plate meshing with the gear is fixed to the side of the mounting frame close to the fixing seat, a cavity is defined in the inner wall of the support rod, a connecting pipe A connecting the airbag with the cavity is fixed to the airbag and the support rod, a mounting groove is defined on the side of the support rod, an inflatable bag is fixed to the mounting groove, and a connecting pipe B connecting the inflatable bag with the cavity is fixed to the inflatable bag and the support rod.

[0008] A connecting cavity connected to the cavity is opened at one end of the support rod, a positioning spring is fixed in the connecting cavity, a sealing plug that is in sliding contact with the connecting cavity is fixed at the other end of the positioning spring, and a connecting rod that passes through the support rod is fixed on the other side of the sealing plug.

[0009] The limiting mechanism includes a limiting shell fixed to the inner bottom wall of the storage box, a compression spring is fixed to the inner wall of the limiting shell, a sliding column is fixed to the other end of the compression spring, a ball is rotatably connected to the other end of the sliding column, a sliding groove is opened on the side of the limiting shell, and a sliding rod is fixed to the side of the sliding column.

[0010] Furthermore, a protection pad is fixed to a side of the mounting frame away from the airbag, and the outer contour of the protection pad is cylindrical.

[0011] By adopting the above technical solution, the material of the protection pad is rubber, and the protection pad can play a certain buffering role on the waterproof coiled material, thereby preventing the bottom of the waterproof coiled material from being subjected to severe vibration.

[0012] Furthermore, a sealing gasket is fixed to the side of the sealing plug that contacts the connecting cavity, and the sealing gasket is externally arranged on the side of the connecting rod.

[0013] By adopting the above technical solution, the provision of a sealing gasket can further improve the sealing effect between the sealing plug and the cavity, thereby avoiding air leakage between the sealing plug and the connecting cavity.

[0014] Furthermore, a rotation groove is provided on the side surface of the support rod, and a rotating rod is rotatably connected inside the rotation groove.

[0015] By adopting the above technical solution, when the waterproof membrane is inserted into the support rod, the waterproof membrane can be supported by the rotating rod, so that the waterproof membrane slides on the rotating rod, and the rotating rod rotates on the rotating groove. The coordinated setting of the rotating groove and the rotating rod can reduce the friction between the waterproof membrane and the support rod, so that the waterproof membrane can be inserted into the support rod more smoothly.

[0016] Furthermore, the thickness of the inflatable bag is smaller than the depth of the mounting groove.

[0017] By adopting the above technical solution, the thickness of the inflatable bag is smaller than the depth of the installation groove. When the waterproof membrane is inserted into the horizontal support rod, the waterproof membrane and the inflatable bag do not contact each other, so that the waterproof membrane can be smoothly inserted into the support rod, avoiding the inflatable bag from obstructing the inserted waterproof membrane.

[0018] Furthermore, a limiting groove connected to the sliding groove is formed on the side surface of the limiting shell, and the inner diameter of the limiting groove is larger than the inner diameter of the sliding rod.

[0019] By adopting the above technical solution, the sliding rod can be rotated into the limiting groove. At this time, the sliding rod is limited by the limiting groove, and the elastic force released by the compression spring will make the sliding rod firmly stuck in the mounting frame. When the sliding rod is stuck in the limiting groove, the sliding column does not limit the support rod. At this time, the waterproof membrane can be moved to a horizontal state by rotating the support rod.

[0020] Furthermore, a box cover is hingedly connected to the front of the storage box through a hinge, a support column is fixed to the box cover, a sealing strip is fixed to a side of the box cover close to the storage box, and a connecting component is provided on the storage box and the box cover.

[0021] By adopting the above technical solution, a box cover is provided to seal the storage box, thereby preventing external dust and other impurities from contaminating the waterproof coiled material inside the storage box. The box cover can be supported by support columns, and a sealing strip is provided to improve the sealing between the storage box and the box cover, thereby preventing dust and other impurities from entering the storage box through the gap between the storage box and the box cover.

[0022] Furthermore, universal wheels are fixed to the bottom surface of the storage box, and the number of the universal wheels is four.

[0023] By adopting the above technical solution, universal wheels are provided to facilitate the movement of the storage box, so that the storage box can be moved to a suitable position, thereby improving the flexibility of the device.

[0024] Furthermore, the connecting assembly includes a connecting plate A fixed on the box cover, a threaded sleeve is fixed on the side of the connecting plate A, the internal thread of the threaded sleeve is connected to a threaded rod passing through the connecting plate A, and a connecting plate B is fixed on the top surface of the storage box, and a through hole is opened on the connecting plate B.

[0025] By adopting the above technical solution, the threaded rod is rotated and moves on the threaded sleeve until the threaded rod moves into the through hole opened on the connecting plate B. The storage box and the box cover can be fixed together through the cooperation of the connecting plate A, the threaded rod and the connecting plate B.

[0026] Furthermore, a knob is fixed to one end of the threaded rod, and the outer contour of the knob is cylindrical.

[0027] By adopting the above technical solution, a knob is provided to facilitate the rotation of the threaded rod, which provides a reasonable force point for rotating the threaded rod and is more convenient to use.

[0028] Compared with the prior art, the storage and handling device for top waterproofing materials in building construction has the following advantages:

[0029] Beneficial effects:

[0030] 1. The present invention facilitates the removal or storage of waterproof membranes by means of a horizontal support rod. When the waterproof membranes are stored, the protective pad, the mounting frame and the airbag are squeezed by the waterproof membrane, so that the gas inside the airbag enters the interior of the airbag from the connecting pipe A, the cavity and the connecting pipe B in sequence, causing the airbag to produce elastic deformation, thereby fixing the waterproof membrane from the inside, avoiding a large gap between the support rod and the waterproof membrane, which would cause the waterproof membrane to shake.

[0031] 2. In the process of squeezing the protective pad, the mounting frame and the airbag by the waterproof membrane of the present invention, the mounting frame will be driven to slide on the support rod, and then the mounting frame drives the gear to rotate through the toothed plate, and the rotating gear will drive the rotating shaft and the support rod to rotate until the support rod drives the connecting rod to resist the ball. At this time, the support rod continues to be rotated, and the elastic force released by the deformation of the compression spring will drive the sliding column and the ball to squeeze the connecting rod, so that the connecting rod drives the sealing plug to move in the connecting cavity, and then the gas inside the connecting cavity is pushed into the cavity, the connecting pipe B, and the inflatable bag in sequence. At this time, the inflatable bag continues to expand, thereby further improving the fixing effect of the waterproof membrane. At the same time, the sliding column is inserted into the support rod to limit the support rod so that it cannot rotate, thereby completing the vertical fixation of the support rod. Through the cooperation of the above-mentioned components, the waterproof membrane can be adjusted to a vertical state and fixed from the inside, while avoiding the weight of the waterproof membrane being concentrated on its bottom edge when it is taken out, which makes the bottom edge of the waterproof membrane vulnerable to damage.

[0032] Second, the present invention facilitates the rotation of the threaded rod by providing a knob, and provides a reasonable force point for rotating the threaded rod. When the threaded rod is rotated, the threaded rod will move on the threaded sleeve until the threaded rod moves into the through hole provided on the connecting plate B. The storage box and the box cover can be fixed together by the cooperation of the connecting plate A, the threaded rod and the connecting plate B. The box cover can be provided to seal the storage box to prevent external dust and other impurities from polluting the waterproof coiled material inside the storage box. The box cover can be supported by the support column. The sealing strip can be provided to improve the sealing between the storage box and the box cover to prevent dust and other impurities from entering the storage box through the gap between the storage box and the box cover. The sealing gasket can further improve the sealing effect between the sealing plug and the cavity to prevent air leakage between the sealing plug and the connecting cavity.

[0033] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0048] See also Figure 1-8 The present invention provides a technical solution: a storage and handling and conveying device for top waterproof materials in construction, comprising a box body 1, wherein the box body 1 comprises a storage box 101, a box cover 102 is hingedly connected to the front of the storage box 101 through a hinge, the storage box 101 can be closed through the box cover 102 to improve the dustproof effect, a support column 104 is fixed on the box cover 102, the box cover 102 can be supported by the support column 104, a sealing strip 103 is fixed on the side of the box cover 102 close to the storage box 101, the sealing strip 103 can improve the sealing effect between the storage box 101 and the box cover 102, and a universal wheel 105 is fixed to the bottom surface of the storage box 101, the number of the universal wheels 105 is four, and the universal wheel 105 is provided to facilitate the movement of the device.

[0049] Please refer to Figure 1 and Figure 7A connecting assembly 4 is provided on the storage box 101 and the box cover 102, and the connecting assembly 4 includes a connecting plate A401 fixed on the box cover 102, a threaded sleeve 402 is fixed on the side of the connecting plate A401, and the internal thread of the threaded sleeve 402 is connected to a threaded rod 403 that penetrates the connecting plate A401, and a connecting plate B404 is fixed on the top surface of the storage box 101, and a through hole is opened on the connecting plate B404, and a knob 405 is fixed at one end of the threaded rod 403, and the outer contour of the knob 405 is cylindrical. The knob 405 is provided to facilitate the rotation of the threaded rod 403, and provides a reasonable force point for rotating the threaded rod 403, which is convenient to use.

[0050] Specifically, after the box cover 102 is rotated to a vertical state, the threaded rod 403 is rotated by means of the knob 405, and the threaded rod 403 will move on the threaded sleeve 402 until the threaded rod 403 moves into a through hole provided on the connecting plate B404. The storage box 101 and the box cover 102 can be fixed together by means of the cooperation of the connecting plate A401, the threaded rod 403 and the connecting plate B404.

[0051] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 A rotating fixing mechanism 2 is provided in the storage box 101. The rotating fixing mechanism 2 includes a fixing seat 201 fixed to the inner bottom wall of the storage box 101. A rotating shaft 202 is rotatably connected to the fixing seat 201. A support rod 203 is fixed to one end of the rotating shaft 202. A gear 204 is fixed to the other end of the rotating shaft 202. A fixing plate 205 is fixed to the side of the support rod 203. An air bag 206 is fixed to the fixing plate 205. A mounting frame 207 slidably connected to the side of the support rod 203 is fixed to the other side of the air bag 206. The material of the mounting frame 207 is relatively hard. Under the push of the waterproof coiled material, the mounting frame 207 can squeeze the airbag 206, causing the airbag 206 to deform, squeezing the gas inside the airbag 206 into the cavity 210, and at the same time, the mounting frame 207 can drive the tooth plate 208 to rotate. A protective pad 217 is fixed to the side of the mounting frame 207 away from the airbag 206. The outer contour of the protective pad 217 is cylindrical, and the material of the protective pad 217 is rubber. The protective pad 217 can play a certain buffering role on the waterproof coiled material to prevent the bottom of the waterproof coiled material from being subjected to severe vibration.

[0052] A tooth plate 208 meshing with the gear 204 is fixed on one side of the mounting frame 207 close to the fixing seat 201, a cavity 210 is provided on the inner wall of the support rod 203, a connecting pipe A209 connecting the airbag 206 and the cavity 210 is fixed on the airbag 206 and the support rod 203, a mounting groove 212 is provided on the side of the support rod 203, an inflatable bag 213 is fixed on the mounting groove 212, the thickness of the inflatable bag 213 is less than the depth of the mounting groove 212, when the waterproof membrane is inserted into the horizontal support rod 203, the waterproof membrane and the inflatable bag 213 do not contact, so that the waterproof membrane can be smoothly inserted into the support rod 203, and a connecting pipe B211 connecting the inflatable bag 213 and the cavity 210 is fixed on the airbag 213 and the support rod 203.

[0053] Specifically, after the waterproof membrane is inserted into the support rod 203, the protective pad 217 is squeezed by the waterproof membrane, and the protective pad 217 will drive the mounting frame 207 to squeeze the airbag 206. Therefore, the gas inside the airbag 206 will enter the cavity 210 from the connecting pipe A209, and then the gas inside the cavity 210 will enter the inflatable bag 213 through the connecting pipe B211, so that the inflatable bag 213 will produce elastic deformation, and the elastically deformed inflatable bag 213 will fit with the waterproof membrane, and then fix it from the inside of the waterproof membrane.

[0054] A connecting cavity 221 connected to the cavity 210 is formed at one end of the support rod 203, and a positioning spring 214 is fixed in the connecting cavity 221. The positioning spring 214 can play a role in positioning the sealing plug 215. The elastic force of the positioning spring 214 is smaller than the elastic force of the compression spring 302. A sealing plug 215 that is in sliding contact with the connecting cavity 221 is fixed at the other end of the positioning spring 214, and a connecting rod 216 that passes through the support rod 203 is fixed on the other side of the sealing plug 215.

[0055] A sealing gasket 218 is fixed on the side of the sealing plug 215 that contacts the connecting cavity 221. The provision of the sealing gasket 218 can further improve the sealing effect. The sealing gasket 218 is externally arranged on the side of the connecting rod 216. A rotating groove 219 is opened on the side of the support rod 203. The interior of the rotating groove 219 is rotatably connected with a rotating rod 220. When the waterproof membrane is inserted into the support rod 203, the rotating rod 220 can support the waterproof membrane so that the waterproof membrane slides on the rotating rod 220, and the rotating rod 220 will rotate on the rotating groove 219. The coordinated setting of the rotating groove 219 and the rotating rod 220 can reduce the friction between the waterproof membrane and the support rod 203, so that the waterproof membrane can be inserted into the support rod 203 more smoothly.

[0056] Specifically, when the connecting rod 216 is squeezed by the sphere 304, it will slide in the support rod 203. The moving connecting rod 216 will drive the sealing plug 215 to move in the connecting cavity 221. The gas inside the connecting cavity 221 can be pushed out into the cavity 210 through the sealing plug 215. Then the gas will enter the installation groove 212 from the cavity 210 and the connecting pipe B211. The gas inside the inflatable bag 213 increases, and the inflatable bag 213 will continue to deform. The inflatable bag 213 fits the waterproof membrane more closely, further improving the fixing effect of the waterproof membrane.

[0057] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 A limiting mechanism 3 for limiting the rotation and fixing mechanism 2 is also provided in the storage box 101. The limiting mechanism 3 includes a limiting shell 301 fixed to the inner bottom wall of the storage box 101. A compression spring 302 is fixed to the inner wall of the limiting shell 301. A sliding column 303 is fixed to the other end of the compression spring 302. A ball 304 is rotatably connected to the other end of the sliding column 303. When the ball 304 contacts the side of the support rod 203, the compression spring 302 is in a compressed state. Referring to the limiting mechanism 3 in the figure, a sliding groove 305 is opened on the side of the limiting shell 301, and a sliding rod 306 is fixed to the side of the sliding column 303.

[0058] A limiting groove 307 connected to the slide groove 305 is provided on the side of the limiting shell 301. The slide rod 306 can be inserted into the limiting groove 307 by rotating the slide rod 306. The inner diameter of the limiting groove 307 is larger than the inner diameter of the slide rod 306, thereby limiting the slide column 303, so that the slide column 303 cannot move under the elastic force released by the compression spring 302. At this time, the slide column 303 no longer limits the support rod 203, and the waterproof membrane can be moved to a horizontal state by rotating the support rod 203.

[0059] Working principle: The support rod 203 in a horizontal state is convenient for taking out the waterproof membrane, and the weight of the waterproof membrane will not be entirely applied to the edge of its bottom. When storing the waterproof membrane, first insert the waterproof membrane into the support rod 203, and the waterproof membrane can slide on the rotating rod 220, and then push the waterproof membrane to squeeze the protective pad 217, the mounting frame 207, and the air bag 206 through the waterproof membrane. After the air bag 206 is squeezed, the gas inside the air bag 206 enters the interior of the inflatable bag 213 from the connecting pipe A209, the cavity 210, and the connecting pipe B211 in turn, so that the inflatable bag 213 produces elastic deformation. The elastically deformed inflatable bag 213 will gradually fit with the waterproof membrane, and then fix it from the inside of the waterproof membrane to avoid a large gap between the support rod 203 and the waterproof membrane, which causes the waterproof membrane to shake. Furthermore, in the process of squeezing the protection pad 217, the mounting frame 207, and the airbag 206 by the waterproof coiled material, the mounting frame 207 will slide on the support rod 203, so that the mounting frame 207 drives the gear 204 to rotate through the tooth plate 208, and the rotating gear 204 will drive the rotating shaft 202 and the support rod 203 to rotate until the support rod 203 drives the connecting rod 216 to resist the ball 304. At this time, the support rod 203 continues to rotate, and the elastic force released by the deformation of the compression spring 302 will drive the sliding column 303 and the ball 304 to squeeze the connecting rod 216, so that the connecting rod 216 drives the sealing plug 215 to move in the connecting cavity 221, and the sealing plug 215 is moved by the sealing plug 215. The plug 215 pushes the gas inside the connecting cavity 221 to the cavity 210, the connecting tube B211, and the air bag 213 in turn. At this time, the gas inside the air bag 213 increases, and the air bag 213 will continue to expand, thereby further improving the fixing effect of the waterproof membrane. At the same time, the support rod 203 can be limited by inserting the sliding column 303 into the support rod 203, so that it cannot rotate, thereby completing the vertical fixation of the support rod 203. Through the cooperation of the above-mentioned components, the waterproof membrane can be adjusted to a vertical state and fixed from the inside, while preventing the weight of the waterproof membrane from being concentrated on its bottom edge when it is taken out, causing the bottom edge of the waterproof membrane to be easily damaged.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
