Description

Technical Field

[0001] The invention relates to the technical field of concrete dam construction, and in particular to intelligent concrete dam rolling construction equipment. Background Art

[0002] A concrete dam is a dam made of concrete pouring, rolling or assembly with precast concrete blocks. Intelligent concrete dam rolling construction equipment is a modern and automated construction machinery dedicated to the compaction of concrete dams. Intelligent concrete dam rolling construction equipment is a product of the development of modern engineering technology. It combines intelligent control, automated operation and modern construction technology to improve construction efficiency and quality.

[0003] The earth dam soil material full-section rolling construction device and method with patent publication number CN108252271A include a vibrating roller, a positioning device is provided on the vibrating roller; a plurality of protrusions are provided on the roller surface of the vibrating roller. The protrusions are arranged in a staggered manner along the axial direction of the roller body and are evenly distributed along the circumference of the roller body; the cross section of the protrusion is trapezoidal. The vibrating roller with protrusions on the roller surface is used to roll the full section of the earth dam soil material. Through the above steps, intelligent monitoring of the rolling construction quality is achieved. By using a vibrating roller with protrusions, in the process of compacting the soil material, not only the weight and vibration of the roller are used, but also the combined effect of squeezing and kneading the soil when the trapezoidal protrusions are inserted into the soil body, which further increases the compaction degree of the soil body, ensures good interlayer bonding of the soil material, eliminates the planing process, and improves the rolling construction quality. It is particularly suitable for full-section rolling of earth dams in tropical monsoon climate zones to achieve efficient filling of earth dams.

[0004] When rolling a concrete dam, it is often necessary to use a rebound meter to detect the concrete strength. According to the detected concrete strength, the pressure applied to the rolled concrete dam is adjusted in real time to achieve the best compaction effect. However, the rolling construction device based on the above and similar principles does not have a mechanism for detecting the concrete strength and changing the pressure applied to the concrete dam, and thus has the disadvantage of incomplete intelligence. When it detects the concrete strength and changes the pressure applied to the concrete dam, additional detection or adjustment is required by staff. At the same time, due to the influence of the natural environment, when rolling construction of a concrete dam is carried out in a place with high or low temperature, temperature factors may cause physical discomfort to the staff. At the same time, in a scene with a large temperature difference, the moisture in the concrete will be evaporated or frozen, which will affect the strength and compaction effect after rolling. Therefore, the present invention is proposed. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Rolling a concrete dam can significantly improve the compactness of the concrete, reduce the porosity, and thus enhance the anti-penetration ability and durability of the dam body. In the process of concrete dam construction, rolling construction equipment is needed.

[0023] It should be noted that the vehicle body 1 is a carrier for controlling the movement of the rolling mechanism 4. The vehicle body 1 can be driven automatically or manually. The rolling mechanism 4 can heat the concrete while rolling the concrete surface, so that the ice on the concrete surface melts, so as to improve the strength and compaction effect after rolling. The wetting mechanism 2 can moisten the concrete when the humidity is low. The strength and compaction effect after rolling can be improved by moistening and rolling the concrete. The strength of the concrete can be detected by the strength detection mechanism 5. According to the strength of the concrete, the pressure applied to the concrete by the rolling mechanism 4 can be changed in cooperation with the pressure adjustment mechanism 10. Small, in order to achieve the purpose of controlling the rolling effect, avoid excessive pressure, resulting in cracks or other defects in the concrete, through the cleaning mechanism 6, the strength detection mechanism 5 can clean the concrete surface before detection, remove impurities, so as to improve the concrete strength detection result of the strength detection mechanism 5, the lifting component 13 is a component that provides a lifting function, the lifting component 13 can be a hydraulic cylinder and an electric push rod, etc., when the strength detection mechanism 5 needs to be used, and the electromagnet column 16 is energized, so that one end of the piston rod of the lifting component 13 is adsorbed on the electromagnet column 16, and the lifting component 13 is started to lift the cross plate 15. During the lifting process of the cross plate 15, the connecting column 509 is driven to move upward. Then, the spring 506 is compressed. When it moves up to the maximum height, the power supply of the electromagnet column 16 is canceled. Under the action of the restoring elastic force of the spring 506, a force is applied to the bottom block 508, the connecting column 509 and the impact head 511, so that the impact head 511 impacts the concrete floor. When impacting on the ground, the impact head 511 moves up through the force fed back by the ground, and the spring 506 is compressed again until the impact head 511 is stable. The initial upward movement distance of the impact head 511 is recorded by the displacement sensor 510, and the concrete strength can be judged. The specific strength judgment can be carried out by using the strength detection mechanism 5 to detect on concrete of different strengths, and the upward movement distance data and strength data of the displacement sensor 510 are obtained. The data taken can be used as a reference to judge the strength of concrete. The pressure value fed back by the set pressure sensor 512 can be used to judge whether the parts or the concrete floor are abnormal. When the pressure generated by the pressure sensor 512 when the impact head 511 impacts is out of the normal range, the staff is reminded to check the parts and concrete floor conditions in the strength detection mechanism 5. The strength detection mechanism 5 can be divided into multiple modules through the set detachable top cover 502, the mounting ring 504 and the spring 506 installed in the positioning groove through the positioning column 505, and the detachable impact head 511, and the modules are detachable, which reduces the difficulty of subsequent maintenance and helps to improve the efficiency of subsequent maintenance.

[0024] like Figure 5 and Figure 6As shown, a drying box 503 is embedded and installed on the bottom inner wall of the top cover 502, and a desiccant is placed in the drying box 503. An oil storage tank 507 for storing lubricating oil is embedded and installed on the bottom block 508. A diverter ring 513 is installed at the bottom of the oil storage tank 507. A nozzle 514 with an output end facing the gap between the bottom block 508 and the measuring ring 501 is installed on the diverter ring 513. A recovery mechanism 7 for recovering the lubricating oil is installed on the measuring ring 501.

[0025] It should be noted that, by means of the drying box 503 and the desiccant, the spring 506 can be made to work in a dry environment, which is beneficial to improving the stability and service life of the spring 506; by means of the oil storage tank 507, the diverter ring 513 and the nozzle 514, the lubricating oil can be sprayed on the gap between the bottom block 508 and the measuring ring 501, so that the bottom block 508 can slide on the inner wall of the measuring ring 501 more smoothly, reduce the resistance, and facilitate use; by means of the recovery mechanism 7, the lubricating liquid accumulated at the bottom of the measuring ring 501 can be recovered, which is beneficial to saving resources.

[0026] like Figure 4 and Figure 6 As shown, the recovery mechanism 7 includes a trapezoidal ring 705 installed at the bottom opening of the measuring ring 501, a U-shaped recovery box 701 is installed on the protective plate 8, a connecting pipe 702 is installed on the bottom inner wall of the measuring ring 501, a collecting pipe 703 connected to the recovery box 701 is installed on the connecting pipe 702, a collecting pump 704 is installed on the collecting pipe 703, and a valve is installed on the connecting pipe 702 near the measuring ring 501.

[0027] It should be noted that, by setting the trapezoidal ring 705, the lubricating oil can be prevented from flowing out directly from the bottom of the measuring ring 501, which is beneficial to environmental protection. By setting the connecting pipe 702 and the collecting pipe 703 in cooperation with the collecting pump 704, the lubricating oil is pumped into the recovery box 701, and the lubricating oil is recovered, which is beneficial to saving resources and protecting the environment. A liquid collection pipe is installed at the bottom of the recovery box 701.

[0028] like Figure 3 As shown, the rolling mechanism 4 includes a rolling column 401 with a hollow structure inside which is rotatably connected to the mounting frame 3, a ring 402 is installed between the inner walls at both ends of the rolling column 401, and a plurality of heating wires 403 are installed between the inner walls at both ends of the rolling column 401 and located between the rolling column 401 and the ring 402. A plurality of annular grooves 404 are opened on the outer wall of the rolling column 401, and a contact assembly 12 is installed in the annular groove 404 for facilitating the replacement of different rolling parts.

[0029] It should be noted that the concrete surface can be rolled by the rolling column 401, and water is filled in the rolling column 401 and the ring 402 through the heating wire 403 inside the rolling column 401. The water can be heated by the heating wire 403, so that the surface of the rolling column 401 is heated, and then the temperature can be increased to melt the ice on the concrete and roll the concrete. Through the contact component 12, different rolling parts in contact with the concrete surface can be replaced according to usage requirements.

[0030] like Figure 8 and Fig. 9 As shown, the contact assembly 12 includes a fixed box 1202 installed on the top and bottom of the outer wall of the annular groove 404, two contact rings 1201 are inserted into the annular groove 404, and the contact rings 1201 are provided with limit grooves 1204 on the outer walls facing the fixed box 1202. A main gear 1207 is rotatably connected to the middle of the bottom inner wall of the fixed box 1202, and two ends of the main gear 1207 are meshed with sub-gears 1208. A limit plate 1209 is installed on the sub-gear 1208, and the limit plate 1209 is inserted into the contact ring 1201 through the fixed box 1202. In the limiting groove 1204, a box cover 1203 is installed on the fixed box 1202, and a rotating block 1205 fixedly connected to the top outer wall of the main gear 1207 is embedded in the box cover 1203. The bottom outer wall of the box cover 1203 is fixedly connected with a damping ring 1206 sleeved on the outer wall of the rotating block 1205. By rotating the rotating block 1205, the main gear 1207, the sub-gear 1208 and the limiting plate 1209 are driven to rotate until the limiting plate 1209 is in contact with the inner wall of the limiting groove 1204, completing the contact ring 1201 being fixed in the annular groove 404.

[0031] It should be noted that, the outer wall of the contact ring 1201 facing outward can be rolled with a protrusion to increase the contact area according to usage requirements. The specific outer wall of the contact ring 1201 facing outward is designed according to actual usage requirements. The position of the contact ring 1201 can be fixed by setting a fixing box 1202 and the components inside the fixing box 1202 cooperating with the limiting groove 1204 on the contact ring 1201. By rotating the main gear 1207, the two sub-gears 1208 are driven to rotate. The limiting plate 1209 is driven to rotate by the rotation of the sub-gear 1208. The limiting plate 1209 is inserted into the limiting groove 1204 and fits with the inner wall of the limiting groove 1204 to fix the position of the contact ring 1201. By setting a damping ring 1206, the force required to rotate the rotating block 1205 can be increased to reduce the possibility of misoperation and facilitate use. The contact ring 1201 should be made of heat-conducting material.

[0032] like Figure 2 and Figure 3As shown, the pressure regulating mechanism 10 includes two partitions 1004 installed in the ring 402, and the space in the ring 402 is divided into two boundary spaces and a central space by the two partitions 1004. Liquid storage tanks 1001 are installed on the outer walls at both ends of the vehicle body 1, and a regulating pipe 1002 is installed on the liquid storage tank 1001. The other end of the regulating pipe 1002 is located in the boundary space of the ring 402. A regulating pump 1003 and a liquid valve are installed on the regulating pipe 1002. A sealed bearing is installed at the contact portion between the regulating pipe 1002 and the rolling column 401. A connecting pipe 1005 connected to the space formed between the inner wall of the rolling column 401 and the outer wall of the ring 402 is installed on the outer wall at the center space of the ring 402, and a connecting valve is installed on the connecting pipe 1005.

[0033] It should be noted that, by setting up the connecting pipe 1005 in cooperation with the connecting valve, the water or other heating liquid located between the inner wall of the rolling column 401 and the outer wall of the ring 402 can be introduced into the central space to store the water or other heating liquid, thereby achieving a heat preservation effect. By setting up the liquid storage tank 1001, the regulating pipe 1002, and the regulating pump 1003, the liquid located in the liquid storage tank 1001 can be transported to the two boundary spaces in the rolling column 401. At the same time, the liquid in the boundary space can also be transported to the liquid storage tank 1001 in the opposite direction, and when transporting the liquid, only one of the boundary spaces can be transported, thereby achieving the concrete strength feedback by the strength detection mechanism 5. The pressure applied to the concrete can be adjusted, and the adjustment can also be based on the position detected by the strength detection mechanism 5. The corresponding position of the rolling column 401 can be individually adjusted for pressure, which is convenient for use.

[0034] like Figure 2 As shown, the wetting mechanism 2 includes a water tank 201 installed on the vehicle body 1, a diverter plate 202 is installed on the bottom outer wall of the water tank 201, and a plurality of nozzles 203 with output ends facing the rolling column 401 are installed on the diverter plate 202.

[0035] It should be noted that when the wetting mechanism 2 is needed, water or other wetting liquids are sprayed onto the surface of the rolling column 401 through the nozzle 203 in cooperation with the diverter plate 202 and the water tank 201. By wetting the surface of the rolling column 401 and then rotating the rolling column 401, the concrete surface can be wetted, which is beneficial for cleaning the surface of the rolling column 401 before wetting the concrete surface.

[0036] like Figure 7 As shown, the cleaning mechanism 6 includes a slot block 601 mounted on the protective plate 8 and corresponding to the position of the measuring ring 501 , an air blowing fan 603 is installed inside the slot block 601 , and filter plates 602 are installed on the top and bottom of the slot block 601 .

[0037] It should be noted that when the cleaning mechanism 6 needs to be used, the dust and impurities on the concrete surface are removed by starting the air fan 603 in the slot block 601 to ensure the normal operation of the strength detection mechanism 5, which is beneficial to improving the accuracy of the strength detection. The filter plate 602 is set to prevent external impurities from affecting the operation of the air fan 603.

[0038] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, a camera 9 is installed on the mounting frame 3, an electromagnet plate 14 is embedded and installed on the outer wall of the protective plate 8 facing the rolling column 401, the cross plate 15 is made of magnetic metal, the ring 402 and the partition 1004 are made of thermal insulation material, a temperature and humidity sensor 17 is installed on the cross plate 15, and a driving wheel 11 is installed on the vehicle body 1.

[0039] It should be noted that, through the camera 9, the staff can observe the rolling condition of the concrete, and through the electromagnet plate 14, the horizontal plate 15 can be adsorbed when it moves to the maximum distance on the horizontal plate 15 to reduce the pressure of the lifting component 13.
