Description

Technical Field

[0001] The invention belongs to the technical field of cement manhole cover maintenance, and in particular relates to a maintenance device for cement manhole cover production. Background Art

[0002] In the process of cement manhole cover production, cement manhole cover maintenance is a key link to ensure its performance. During maintenance, it is necessary to cover the moisturizing material in time after casting and forming, and water it regularly to keep the surface moist. The reason is that cement is a hydraulic material and needs to react with water to form cement stone crystals in order to bond the sand and gravel aggregates into a solid whole. If there is a lack of water, the hydration reaction will be insufficient, resulting in insufficient strength, and the rapid evaporation of surface moisture will easily cause cracks due to shrinkage. At the same time, during the maintenance process, by controlling the humidity and temperature, the slow growth of cement crystals can be promoted, the crack resistance and durability of the manhole cover can be enhanced, and its compressive and flexural strength can meet the design requirements, avoiding problems such as loose structure and performance degradation due to improper maintenance, thereby ensuring the safety and service life of the manhole cover in use.

[0003] The existing maintenance of cement manhole covers is mostly achieved by sprinkling water on the manhole covers placed on the ground. At the same time, some water-absorbing materials are placed on the manhole covers or wet sacks, straw mats, etc. are used to cover the manhole covers to reduce the evaporation rate. This method will result in low space utilization. At the same time, due to the fast evaporation rate, the watering cycle will be shorter, increasing the workload. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a maintenance device for cement manhole cover production.

[0005] The technical solution adopted to solve the above technical problems is: to provide a maintenance device for cement manhole cover production, comprising a device base, a device housing is fixedly connected to the top of the device base, and a sealing door is rotatably connected to one side of the front end surface of the device housing;

[0006] A plurality of bottom wrapping guide mechanisms are installed between the two sides of the inner wall of the device shell, a top wrapping guide mechanism is provided between the two sides of the device shell, and a pumping assembly is fixedly connected to the top of the device shell;

[0007] A drying mechanism is provided on one side of the device shell, and two air outlets are fixedly connected to the bottom of the device shell near the drying mechanism. Cement manhole cover bodies are placed on multiple bottom-wrapped guide mechanisms, and a water outlet pipe is fixedly connected to the bottom of the rear end face of the device shell.

[0008] The top of the rotating plate is fixedly connected to the bottom wrapping geotextile, and a plurality of reinforcing support rods are provided inside the rotating plate. The rotating plate has a plurality of reinforcing support rods, and a plurality of reinforcing support rods are provided inside the rotating plate. The rotating plate has a plurality of porous guide grooves on the outside of the bottom wrapping geotextile, and the center of the top front end of the rotating plate is fixedly connected to a threaded block, and a threaded rod is spirally connected to the threaded block. The rear end of the threaded rod is rotatably connected to an arc push plate, and the bottom of the rotating plate is fixedly connected to a centralized guide bucket, and one side of one of the support track assemblies is fixedly connected to a guide sealing plate.

[0009] Through the above technical solution, when placing the cement manhole cover body, the rotating plate is pulled out. When the side guide plate is fully pulled out, the torsion spring will drive the support clamping rod to automatically pop open, and then the entire rotating plate is rotated and then clamped on the support rail assembly of the next bottom wrapped diversion mechanism through two support clamping rods, thereby completing the fixation, placing the cement manhole cover body, and then rotating the threaded rod to push the entire cement manhole cover body toward the center of the bottom wrapped geotextile through the arc-shaped push plate to ensure that the center of the bottom wrapped geotextile and the center of the cement manhole cover body coincide in the vertical direction, and then lift the rotating plate to a horizontal state, and at the same time push the rotating plate to reset the rotating plate. During the pushing process, the support rail assembly will squeeze the support clamping rod and drive it to rotate, compressing the torsion spring while completing automatic storage.

[0010] Furthermore, the rear end of the side guide plate is a triangular structure, the rear end of the bottom of the side guide plate is provided with a groove corresponding to the support rod, and the inner wall of the groove is fixedly connected to the rotating shaft corresponding to the support rod.

[0011] Through the above technical solution, the triangular structure ensures that when the rotating plate is pushed, the entire rotating plate can be formed into a horizontal state through the triangular inclined structure, so that it can be fully inserted between the two supporting rail assemblies.

[0012] Furthermore, the bottom of the bottom geotextile is a conical structure, and the top of the rotating plate is provided with a concave surface corresponding to the conical structure.

[0013] Through the above technical solution, the conical structure of the geotextile wrapped at the bottom ensures that water will gather towards the center when dripping around, and then store water in the concave surface, extending the watering cycle, and through multiple reinforced support rods, it can avoid the situation where the water storage of the geotextile wrapped at the bottom is reduced due to the weight of the cement manhole cover body.

[0014] Furthermore, the guide and blocking plates in the plurality of bottom-wrapped guide mechanisms are distributed in sequence on both sides of the inner wall of the device shell.

[0015] Through the above technical solution, when the device is not in use, an air duct is formed inside the device shell through the drying mechanism due to the guide sealing plates installed on both sides in sequence, thereby completely drying the multiple bottom-wrapped geotextiles and multiple top-wrapped geotextiles inside.

[0016] Furthermore, the top-wrapped diversion mechanism includes two side support plates, the tops of the two side support plates are each installed with a driving motor, the output ends of the two driving motors are each fixedly connected to a transmission screw, a group of transmission plates are spirally connected to the two transmission screws, and hard connecting plates are fixedly connected between the two groups of transmission plates, the tops of multiple hard connecting plates are each fixedly connected to a water inlet ring, the bottoms of multiple hard connecting plates are each fixedly connected to a top-wrapped geotextile, and multiple diversion pipes are installed inside multiple top-wrapped geotextiles.

[0017] Through the above technical solution, after they are placed in sequence, the two drive motors are started to drive the corresponding transmission screws, and then multiple hard connecting plates are driven to move downward at the same time, so that multiple top-wrapped geotextiles fit the top of the cement manhole cover body, and then the pumping assembly is connected to the water source and started. Water flows in from the water inlet ring on the top hard connecting plate, and continuously soaks the top-wrapped geotextile. When the top-wrapped geotextile is completely soaked, the water will penetrate around along the conical structure of the top-wrapped geotextile. At the same time, the infiltration speed can be accelerated through the porous diversion pipe, and then the water is drained through multiple diversion pipes. The flow is guided to flow out, and then drips onto the bottom wrapped geotextile corresponding to the bottom, and then the bottom wrapped geotextile penetrates and continuously penetrates toward the center through the conical structure at its bottom. When the bottom wrapped geotextile is completely soaked, the excess water will flow out to the surroundings, remain through the porous diversion groove on the outside, and then be guided to the center position through the centralized diversion bucket to flow out, and then flow to the next water inlet ring and the top wrapped geotextile. This process can complete the immersion of multiple bottom wrapped geotextiles and multiple top wrapped geotextiles, and finally close the pumping assembly after the water output from the outlet pipe is stable.

[0018] Furthermore, the top of the top-wrapped geotextile is a conical structure, and the inner wall of the hard connecting plate is a concave structure corresponding to the conical structure of the top-wrapped geotextile, and the multiple diversion tubes are all porous structures.

[0019] Through the above technical solution, the conical structure with geotextile wrapped on the top ensures that the water flow will quickly spread to the surroundings when water enters the top. After being completely soaked, the excess water can be quickly drained out through the porous structure of the diversion pipe.

[0020] Furthermore, the drying mechanism includes a drying device, the output end of the drying device is fixedly connected to a transmission square tube, and two connecting square tubes are fixedly connected between the other end of the transmission square tube and the top of one side of the device shell.

[0021] Through the above technical solution, the drying equipment is started, and dry hot air enters through the transmission square tube and the two connecting square tubes, continuously drying the bottom geotextile and the top geotextile. At the same time, due to the guide blocking plates installed on both sides in sequence, an air duct is formed, and finally blown out from the two air outlets, avoiding the generation of odor by the wet bottom geotextile and the top geotextile.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention realizes wrapping of both sides of the cement manhole cover by designing a bottom wrapping diversion mechanism and a top wrapping diversion mechanism. At the same time, the design of multiple bottom wrapping diversion mechanisms and multiple bottom wrapping geotextiles can continuously immerse multiple top wrapping geotextiles and multiple bottom wrapping geotextiles through the release of water flow from the top during use, thereby realizing the maintenance of multiple cement manhole covers. At the same time, the stacked cement manhole covers can effectively improve the space utilization rate, and the overall device can effectively reduce the evaporation rate of water and extend the watering cycle; (2) The present invention can respectively realize the bottom wrapping geotextile and the top wrapping geotextile by designing the conical structure at the bottom of the bottom wrapping geotextile and the conical structure at the top of the top wrapping geotextile. The conical structure of the geotextile ensures that water will gather toward the center when dripping around, and then store water in the concave surface, extending the watering cycle, and ensuring that water will quickly spread to the surroundings when water enters the top. After being completely soaked, the excess water can be quickly drained out through the diversion tube with a porous structure. At the same time, reinforcing support rods are added to the bottom geotextile wrapped at the bottom of the cement manhole cover to avoid the situation where the water storage of the bottom geotextile wrapped is reduced due to the weight of the cement manhole cover body; (3) The present invention forms an air duct inside the device by designing a drying mechanism, which can completely dry multiple bottom geotextiles and top geotextiles inside the device, avoiding the generation of odor by the wet bottom geotextiles and top geotextiles.

[0045] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] like Figure 1-Figure 3 As shown, a maintenance device for cement manhole cover production in this embodiment includes a device base 1, a device shell 2 is fixedly connected to the top of the device base 1, and a sealing door 3 is rotatably connected to one side of the front end surface of the device shell 2.

[0047] like Figure 1-Figure 3 and Figures 9-17As shown, a plurality of bottom-wrapped flow-guiding mechanisms 4 are installed between the two sides of the inner wall of the device shell 2. The bottom-wrapped flow-guiding mechanism 4 includes two support rail assemblies 401 fixedly connected to the inner wall of the device shell 2. The inner walls of the two support rail assemblies 401 are slidably connected with a sliding shaft seat 402. A rotating plate 403 is rotatably connected between the two support rail assemblies 401. Both sides of the rotating plate 403 are fixedly connected with side guide plates 404. The rear ends of the bottoms of the two side guide plates 404 are rotatably connected with support clamping rods 405. Torsion springs 406 are installed between the two support clamping rods 405 and the corresponding side guide plates 404. The top center of the rotating plate 403 is fixedly connected with a bottom-wrapped geotextile 407. The bottom-wrapped geotextile 40 7 is provided with a plurality of reinforcing support rods 408 inside, and the rotating plate 403 is provided with a porous diversion groove 409 on the outside of the geotextile 407 wrapped at the bottom, and the center of the top front end of the rotating plate 403 is fixedly connected with a threaded block 410, and a threaded rod 411 is spirally connected to the threaded block 410, and the rear end of the threaded rod 411 is rotatably connected with an arc-shaped push plate 412, and the bottom of the rotating plate 403 is fixedly connected with a centralized diversion bucket 413, and one side of one of the support track components 401 is fixedly connected with a diversion blocking plate 414. When placing the cement manhole cover body 9, the rotating plate 403 is pulled out. When the side guide plate 404 is fully pulled out, the torsion spring 406 will drive the support clamping rod 405 to automatically pop open, and then the entire rotating plate 403 is rotated to The two support rods 405 are used to clamp the support rail assembly 401 of the next layer of bottom wrapped diversion mechanism 4 (the bottom layer does not need to install the support rod 405), thereby completing the fixation, placing the cement manhole cover body 9, and then rotating the threaded rod 411 to push the entire cement manhole cover body 9 toward the center of the bottom wrapped geotextile 407 through the arc push plate 412, ensuring that the center of the bottom wrapped geotextile 407 and the center of the cement manhole cover body 9 coincide in the vertical direction, and then lift the rotating plate 403 to a horizontal state, and push the rotating plate 403 to reset the rotating plate 403. During the pushing process, the support rail assembly 401 will squeeze the support rod 405 and drive it to rotate, compressing the torsion spring 4 06, and automatically retracts at the same time. The rear end of the side guide plate 404 is a triangular structure, and a groove corresponding to the support clamping rod 405 is provided at the rear end of the bottom of the side guide plate 404, and the inner wall of the groove is fixedly connected to the rotating shaft corresponding to the support clamping rod 405. The triangular structure ensures that when the rotating plate 403 is pushed, the triangular inclined surface structure can be used to make the entire rotating plate 403 form a horizontal state, so that it can be fully inserted between the two supporting track assemblies 401. The bottom of the bottom wrapped with geotextile 407 is a conical structure, and the top of the rotating plate 403 is provided with a concave surface corresponding to the conical structure. The conical structure of the bottom wrapped with geotextile 407 ensures that water will gather towards the center when dripping around, and then store water in the concave surface, thereby extending the watering cycle.And through multiple reinforcing support rods 408, it is avoided that the water storage of the bottom wrapped geotextile 407 is reduced due to the weight of the cement manhole cover body 9. The diversion blocking plates 414 in the multiple bottom wrapped diversion mechanisms 4 are distributed in sequence on both sides of the inner wall of the device shell 2. When the device is not in use later, the drying mechanism 7 forms an air duct (such as, Figure 21 ), thereby being able to completely dry the multiple bottom wrapped geotextiles 407 and the multiple top wrapped geotextiles 507 inside.

[0048] like Figures 1-17As shown, a top-wrapped flow-guiding mechanism 5 is provided between the two sides of the device shell 2. The top-wrapped flow-guiding mechanism 5 includes two side support plates 501. A driving motor 502 is installed on the top of each of the two side support plates 501. The output ends of the two driving motors 502 are fixedly connected to a transmission screw 503. A set of transmission plates 504 are spirally connected to each of the two transmission screws 503. A hard connecting plate 505 is fixedly connected between the two sets of transmission plates 504. The tops of the multiple hard connecting plates 505 are fixedly connected to a water inlet ring 506. The bottoms of the multiple hard connecting plates 505 are fixedly connected to a top-wrapped geotextile 50 7. Multiple guide tubes 508 are installed inside the multiple top-wrapped geotextiles 507. After they are placed in sequence, start the two drive motors 502 to drive the corresponding transmission screws 503, and then drive the multiple hard connecting plates 505 to move downward at the same time, so that the multiple top-wrapped geotextiles 507 fit the top of the cement manhole cover body 9, and then connect the pumping assembly 6 to the water source and start it. The water flows in from the water inlet ring 506 on the top hard connecting plate 505 (control the water flow not to be too large), and continuously soaks the top-wrapped geotextile 507. When the top-wrapped geotextile 507 is completely soaked, the water will flow along the cone of the top-wrapped geotextile 507 The structure penetrates to the surroundings, and at the same time, the penetration speed can be accelerated through the porous diversion tube 508, and then the water flow is guided out through multiple diversion tubes 508, and then drips onto the bottom geotextile 407 corresponding to the bottom, and then the bottom geotextile 407 penetrates and continuously penetrates to the center through the conical structure at the bottom. When the bottom geotextile 407 is completely soaked, the excess water will flow out to the surroundings, remain through the porous diversion groove 409 on the outside, and then be guided to the center position through the centralized diversion bucket 413 to flow out, and then flow to the next water inlet ring 506 and the top geotextile 507, and continue to do so. Complete the immersion of multiple bottom-wrapped geotextiles 407 and multiple top-wrapped geotextiles 507, and finally close the pumping assembly 6 after the water output from the outlet pipe 10 is stable. The top of the top-wrapped geotextile 507 is a conical structure, and the inner wall of the hard connecting plate 505 is a concave structure corresponding to the conical structure of the top-wrapped geotextile 507. Multiple diversion tubes 508 are all porous structures. The conical structure of the top-wrapped geotextile 507 ensures that the water flow will quickly diffuse to the surroundings when water enters the top. After being completely soaked, excess water can be quickly diverted out through the diversion tube 508 with a porous structure. The top of the device shell 2 is fixedly connected to the pumping assembly 6.

[0049] like Figures 1-21As shown, a drying mechanism 7 is provided on one side of the device shell 2, and the drying mechanism 7 includes a drying device 701. The output end of the drying device 701 is fixedly connected to a transmission square tube 702, and two connecting square tubes 703 are fixedly connected between the other end of the transmission square tube 702 and the top of one side of the device shell 2. When the drying device 701 is started, dry hot air enters through the transmission square tube 702 and the two connecting square tubes 703, continuously drying the bottom geotextile 407 and the top geotextile 507. At the same time, due to the guide sealing plates 414 installed in sequence on both sides, an air duct is formed, and finally blown out from the two air outlets 8 to prevent the wet bottom geotextile 407 and the top geotextile 507 from generating odor. The device shell 2 is fixedly connected to two air outlets 8 at the bottom near the drying mechanism 7 side, and a cement manhole cover body 9 is placed on multiple bottom wrapped guide mechanisms 4. The bottom of the rear end face of the device shell 2 is fixedly connected to a water outlet pipe 10.

[0050] The working principle of this embodiment is as follows: when placing the cement manhole cover main body 9, the rotating plate 403 is pulled out. When the side guide plate 404 is fully pulled out, the torsion spring 406 drives the support clamping rod 405 to automatically pop open, and then the entire rotating plate 403 is rotated and then clamped on the support rail assembly 401 of the next layer of bottom wrapped diversion mechanism 4 through the two support clamping rods 405, thereby completing the fixation, and placing the cement manhole cover main body 9, and then rotating the threaded rod 411 and then pushing the entire cement manhole cover main body 9 to move toward the center of the bottom wrapped geotextile 407 through the arc pushing plate 412, ensuring that the center of the bottom wrapped geotextile 407 and the center of the cement manhole cover main body 9 coincide in the vertical direction, and then lift the rotating plate 403 to a horizontal state, and at the same time push the rotating plate 403 to reset the rotating plate 403. During the pushing process, the support rail assembly 401 squeezes the support clamping rod 405 and drives it to rotate, compressing the torsion spring 406 while completing the automatic retraction;

[0051] After they are placed in sequence, the two driving motors 502 are started to drive the corresponding transmission screws 503, and then the multiple hard connecting plates 505 are driven to move downward at the same time, so that the multiple top-wrapped geotextiles 507 fit the top of the cement manhole cover body 9, and then the pumping assembly 6 is connected to the water source and started. The water flows in from the water inlet ring 506 on the top hard connecting plate 505, and continuously soaks the top-wrapped geotextile 507. When the top-wrapped geotextile 507 is completely soaked, the water will penetrate around along the conical structure of the top-wrapped geotextile 507. At the same time, the infiltration speed can be accelerated through the porous diversion pipe 508, and then the water flow is guided through the multiple diversion pipes 508. The water is diverted out and then drips onto the corresponding bottom geotextile 407 at the bottom. The bottom geotextile 407 then penetrates and continuously penetrates toward the center through the conical structure at the bottom. When the bottom geotextile 407 is completely soaked, the excess water flows out to the surrounding areas, remains through the porous diversion groove 409 on the outside, and is then guided to the center through the centralized diversion bucket 413 to flow out, and then flows to the next water inlet ring 506 and the top geotextile 507. This process is continued to complete the immersion of multiple bottom geotextiles 407 and multiple top geotextiles 507, and finally the pumping assembly 6 is closed after the water output from the outlet pipe 10 is stable.

[0052] When the device is not in use, the two driving motors 502 and the corresponding transmission screws 503 drive the multiple hard connecting plates 505 and the top wrapped geotextile 507 to rise, take out the cement manhole cover, close the sealing door 3, start the drying equipment 701, and the dry hot air enters through the transmission square tube 702 and the two connecting square tubes 703, continuously drying the bottom wrapped geotextile 407 and the top wrapped geotextile 507. At the same time, due to the guide blocking plates 414 installed on both sides in sequence, an air duct is formed inside the device shell 2 (such as Figure 21 ), and finally blown out from the two air outlets 8 to avoid odor from the wet bottom wrapped geotextile 407 and the top wrapped geotextile 507.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
