Description

Technical Field

[0001] The utility model relates to a manhole cover, in particular to an integrated oil cylinder hydraulic manhole cover, belonging to the technical field of hydraulic manhole covers. Background Art

[0002] With the development of urbanization in my country, there are more and more comprehensive underground pipe galleries in cities. The pipe gallery manhole covers are the closures on the tops of the entrances and exits leading to underground facilities. Wherever public facilities such as tap water, cable TV, drainage, telecommunications, mobile, Unicom, electricity, gas, heat, fire protection, and sanitation are installed, inspection wells need to be installed, and pipe gallery manhole covers are usually hydraulically driven cylinder hydraulic manhole covers.

[0003] The hydraulic sealing manhole cover disclosed in the specification of Chinese patent announcement No. CN207484517U realizes the opening and closing of the movable cover body by setting a hydraulic cylinder. The movable arc plate drives the slider to slide in the arc-shaped long hole of the fixed arc plate. The hydraulic cylinder is also provided with a first emergency oil circuit and a second emergency oil circuit. The first emergency oil circuit is connected to the reserved interface of the manual hydraulic pump on the fixed cover body, and the other set is located inside the manhole. When there is a power outage or oil pump failure in the manhole, it can also be hydraulically opened by connecting a manual hydraulic pump outside or inside the well.

[0004] Although the above-mentioned patent can drive the manhole cover to open and close by the hydraulic cylinder, its device is mostly installed on the manhole cover body, making the manhole cover body an easily damaged accessory that needs to be repaired and replaced, and taking on many additional functions. When the manhole cover body is damaged and must be replaced, the installation and disassembly is very inconvenient and the replacement cost is high. It will also affect the normal use of the hydraulic cylinder. At the same time, common manhole covers lack anti-theft measures, which is not conducive to the safe use of the manhole covers.

[0028] Please refer to Figure 2 , Figure 3 and Figure 5The connector 4 includes a support block 401, a connecting pipe 402 is provided on the upper surface of the support block 401, the connecting pipe 402 is fixed to the mounting ring 5, the internal sliding connection of the connecting pipe 402 is connected to the limiting block 403, a limiting groove is provided on the side of the support block 401, the limiting block 403 is engaged with the limiting groove, and the internal sliding connection of the limiting groove is provided with an adjusting block 405, which is beneficial to the stability of the limiting block 403. The mounting ring 5 and the output end of the cylinder body 3 can be connected together through the engagement of the limiting block 403 with the limiting groove. A limiting spring 404 is provided inside the connecting pipe 402, one end of the limiting spring 404 is connected to the connecting pipe 402, and the other end of the limiting spring 404 is connected to the limiting block 403, which is beneficial to the stability of the limiting block 403, so that the limiting block 403 can stably enter the limiting groove under the elastic force of the limiting spring 404.

[0029] Please refer to Figure 1 , Figure 3 and Figure 5 The upper surface of the manhole cover body 2 is rotatably connected with a turntable 7, which penetrates the manhole cover body 2. A driven rod 8 is fixed to the bottom surface of the turntable 7, and an adjusting rod 9 is fixed to the outer surface of the driven rod 8, which is beneficial to the stability of the adjusting block 405. The adjusting rod 9 is driven to rotate by rotating the turntable 7 to push the adjusting block 405 to move. The movement of the adjusting block 405 pushes the limit block 403 to retract back into the connecting tube 402, so that the limit block 403 is disengaged from the limit groove. A card slot is provided on the upper surface of the turntable 7. The size of the card slot is smaller than that of the turntable 7, which is beneficial to the stability of the card slot. The turntable 7 can be driven to rotate by the card slot engaged with a specially shaped card block.

[0030] Please refer to Figure 3 , Figure 4 and Figure 5 A warning light 10 is provided on the upper surface of the manhole cover body 2, an alarm 11 is installed on the bottom surface of the manhole cover body 2, a PLC controller 12 is installed on the inner wall of the derrick 1, the warning light 10 is symmetrically installed, the warning light 10, the alarm and the cylinder body 3 are all electrically connected to the PLC controller 12, a track groove is opened on the inner wall of the derrick 1, and a track plate 13 is slidably connected to the inner wall of the track groove. The track plate 13 is fixed to the mounting ring 5, which is beneficial to the stability of the track plate 13, thereby making the mounting ring 5 stably lifted and lowered.

[0031] The utility model is in use: When in use, if it is necessary to disassemble the manhole cover body 2, first start the cylinder body 3 through the PLC controller 12. The model of the PLC controller 12 is a control system with a small number of Xinjie XC1, which is suitable for general applications. The functions are relatively simple and can perform general functions such as logic control and data calculation. The output end of the cylinder body 3 drives the support block 401 to rise, and the rise of the support block 401 drives the connecting pipe 402 to rise. The rise of the connecting pipe 402 drives the mounting ring 5 to rise. Since the mounting ring 5 is connected to the connecting ring 6 by bolts, the connecting ring 6 is driven to rise, and then drives the manhole cover body 2 to rise, completing the separation of the manhole cover body 2 and the derrick 1. Then the bolts are removed to complete the disassembly of the manhole cover body 2, thereby ensuring that the manhole cover body 2 is not given too many functions, reducing the cost of replacing the damaged manhole cover body 2, and at the same time ensuring that the damaged manhole cover body 2 is replaced simply and quickly.

[0032] When the oil cylinder body 3 fails and cannot be used, the special clamping block is clamped with the clamping slot, and the rotating clamping block drives the turntable 7 to rotate. The rotation of the turntable 7 drives the driven rod 8 to rotate. The rotation of the driven rod 8 drives the adjusting rod 9 to rotate. The adjusting rod 9 pushes the adjusting block 405 to move. The movement of the adjusting block 405 pushes the limit block 403 to disengage from the limit groove and thereby releases the connection between the connecting pipe 402 and the supporting block 401, preventing the manhole cover body 2 from being unable to be replaced when the oil cylinder body 3 fails. At the same time, a specially shaped clamping block is provided to clamp with the clamping slot, thereby ensuring the safety of the manhole cover body 2 and realizing the anti-theft function.
