Description

Technical Field

[0001] The utility model belongs to the technical field of manhole cover pressure testing, and in particular relates to a manhole cover fixing device for a microcomputer-controlled manhole cover testing machine. Background Art

[0002] A manhole cover is a device used to cover the wellhead, usually made of cast iron, steel plate, or concrete. Its main function is to protect the wellhead and prevent people or objects from falling into the well. It also prevents sewage, rainwater, etc. from entering the well, keeping the well clean and hygienic. To ensure the overall quality of the manhole cover during use, it is necessary to test its pressure using a testing machine during production. To ensure the stability of the manhole cover during testing, it is necessary to fix the manhole cover with a fixing device.

[0003] A microcomputer-controlled manhole cover pressure testing machine is disclosed in the Chinese patent website CN211401286U, which includes a base, a groove is opened at the center of the top wall of the base, and mounting grooves are symmetrically opened on both sides of the side walls below the groove. First limit blocks are symmetrically slidably connected in the two mounting grooves, second limit blocks are symmetrically fixedly connected on the front and rear sides of the bottom wall of the groove, and a support is fixedly sleeved on the outer side wall of the base.

[0031] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0032] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0033] See also Figure 1-Figure 7 As shown, the utility model is a manhole cover fixing device for a microcomputer-controlled manhole cover testing machine, comprising a support box 1, an adjustment slot 2 is provided on the top of the support box 1, a plurality of adjustment slots 2 are provided, an adjustment rod 3 is movably connected inside the adjustment slot 2, a drive assembly 4 is provided inside the support box 1, a drive end of the drive assembly 4 is threadedly connected to the adjustment rod 3, a clamping assembly 5 is fixedly connected to the top of the drive assembly 4, a placement table 6 is fixedly connected to the top of the support box 1, an L-shaped support plate 7 is fixedly connected to one side of the support box 1, a lifting assembly 8 is provided on the top of the L-shaped support plate 7, and a pressure monitoring assembly 9 is provided at the bottom of the lifting assembly 8.

[0034] When testing the manhole cover, the manhole cover is directly placed on the top of the placement platform 6, and then the driving component 4 is driven. The driving component 4 drives multiple adjustment rods 3 to move inside the adjustment groove 2 and makes the clamping component 5 be sleeved on the outside of the manhole cover. After the manhole cover is fixed, the lifting component 8 is driven and the pressure of the manhole cover is tested. At this time, the pressure monitoring component 9 can monitor the pressure applied by the lifting component 8 to the manhole cover.

[0035] When fixing the manhole cover on the placement table 6, directly driving the driving component 4 can make multiple adjustment rods 3 drive the corresponding clamping components 5 to complete the fixation of the manhole cover, thereby making the operation of fixing the manhole cover more convenient.

[0036] In one embodiment, for the above-mentioned drive assembly 4, the drive assembly 4 includes a drive screw 401, the outer surface of the drive screw 401 is rotatably connected to the support box 1, and the drive screw 401 is provided with multiple corresponding adjusting rods 3. The drive screw 401 is threadedly connected to the corresponding adjusting rod 3, and one end of the drive screw 401 is fixedly connected to a bevel gear 402, and multiple bevel gears 402 are meshed together. The drive assembly 4 also includes a support frame 403, and a guide column 404 is fixedly connected between the support frame 403 and the inner wall of the support box 1. The adjusting rod 3 is movably connected to the guide column 404, and the drive screw 401 is rotatably connected to the support frame 403. A motor 405 is fixedly installed on the outside of the support box 1, and the output end of the motor 405 passes through the support box 1 and is fixedly connected to one of the drive screws 401.

[0037] By driving the motor 405, the motor 405 drives the driving screw 401 to rotate. At this time, the multiple driving screws 401 rotate synchronously with the assistance of the bevel gear 402, so that the driving screw 401 drives the adjusting rod 3 to move inside the adjusting groove 2. At this time, since the driving screw 401 rotates synchronously, the multiple adjusting rods 3 can also move synchronously inside the adjusting groove 2, so that the adjusting rod 3 is coaxial with the placement table 6 after the manhole cover is fixed by the clamping assembly 5. This phenomenon makes the monitoring effect of the fixed manhole cover better; the guide column 404 can guide the adjusting rod 3, so that the stability of the adjusting rod 3 during movement can be guaranteed; and the setting of the support frame 403 can ensure stability when the bevel gears 402 on the multiple driving screws 401 are engaged together. At the same time, the support frame 403 can support the placement table 6, so that the support box 1 will not collapse due to pressure when the manhole cover is pressure tested.

[0038] In one embodiment, for the above-mentioned clamping assembly 5, the clamping assembly 5 includes an arc-shaped frame 501, the top of the arc-shaped frame 501 is threadedly connected to an adjusting screw 502, the bottom end of the adjusting screw 502 passes through the arc-shaped frame 501 and is rotatably connected to a clamping plate 503, the inner wall of the arc-shaped frame 501 is provided with a guide groove 504, the inside of the guide groove 504 is movably connected to a guide block 505, the guide block 505 is fixedly connected to the clamping plate 503, and the top of the adjusting screw 502 is fixedly connected to a control ring 506.

[0039] The guide block 505 cooperates with the guide groove 504 so that when the adjusting screw 502 pushes the clamping plate 503 downward, the clamping plate 503 will not rotate with the rotation of the adjusting screw 502, thereby ensuring the stability of the clamping plate 503 when it moves downward.

[0040] In one embodiment, for the above-mentioned adjusting rod 3 , the bottom end of the adjusting rod 3 is rotatably connected to a roller 10 , and a reinforcing rib 11 is fixedly connected between the bottom of the arc frame 501 and the adjusting rod 3 .

[0041] When the adjusting rod 3 moves, it can drive the roller 10 to rotate at the bottom of the inner wall of the support box 1. The setting of the roller 10 enables the adjusting rod 3 to better support the manhole cover through the arc frame 501. At the same time, the friction between the adjusting rod 3 and the bottom of the inner wall of the support box 1 is small when moving. The setting of the reinforcing rib 11 improves the overall firmness of the arc frame 501 on the top of the adjusting rod 3.

[0042] In one embodiment, for the above-mentioned lifting assembly 8, the lifting assembly 8 includes a hydraulic cylinder 801, which is fixedly installed on the top of the L-shaped support plate 7. The output end of the hydraulic cylinder 801 passes through the L-shaped support plate 7 and is fixedly connected to a mounting tube 802. The mounting tube 802 is fixedly connected to the pressure monitoring assembly 9, and the moving end of the pressure monitoring assembly 9 is fixedly connected to the pressure plate 803.

[0043] When testing the fixed manhole cover, the hydraulic cylinder 801 is directly driven, and the output end of the hydraulic cylinder 801 pushes the pressure monitoring component 9 downward through the mounting tube 802 and causes the pressure plate 803 to start squeezing the manhole cover. The above operation allows the hydraulic cylinder 801 to be directly driven when testing the manhole cover, and the entire operation is relatively convenient.

[0044] In one embodiment, for the above-mentioned pressure monitoring component 9, the pressure monitoring component 9 includes a storage cylinder 901, the storage cylinder 901 is fixedly connected to the installation cylinder 802, the interior of the storage cylinder 901 is movably connected to a movable disk 902, the interior of the storage cylinder 901 is movably connected to a movable column 903, a spring 904 is fixedly connected between the movable disk 902 and the movable column 903, the inner wall of the storage cylinder 901 is provided with a limiting groove 905, the interior of the limiting groove 905 is movably connected to a limiting block 906, the limiting There are two groups of blocks 906 set up above and below. The two groups of limit blocks 906 are fixedly connected to the corresponding movable disk 902 and movable column 903 respectively. The bottom end of the movable column 903 is fixedly connected to the pressure plate 803. The pressure monitoring component 9 also includes a pressure sensor 907. The pressure sensor 907 is fixedly installed on the top of the storage tube 901. The detection end of the pressure sensor 907 is inside the storage tube 901. A display 908 is fixedly installed on the top of the L-shaped support plate 7, and the display 908 is electrically connected to the pressure sensor 907.

[0045] When the pressure plate 803 starts to squeeze the manhole cover, the moving column 903 starts to move toward the inside of the storage tube 901. At this time, the moving column 903 starts to squeeze the spring 904 and the moving plate 902, and the moving plate 902 squeezes the pressure sensor 907. At this time, the display 908 can display the pressure generated by the moving plate 902 on the pressure sensor 907 in a numerical form. The numerical value at this time also represents the pressure of the pressure plate 803 on the manhole cover. The above setting allows the tester to know more clearly how much pressure the pressure plate 803 exerts on the manhole cover, so that the results obtained when testing the manhole cover are more accurate; the setting of the limit block 906 and the limit groove 905 prevents the moving column 903 from detaching from the inside of the storage tube 901 under the elastic force of the spring 904.

[0046] Through the above technical solution, 1. By driving the motor 405, the motor 405 drives the driving screw 401 to rotate. At this time, with the assistance of the bevel gear 402, multiple driving screws 401 drive the adjusting rod 3 to move synchronously inside the adjusting groove 2, and the clamping assembly 5 at the top of the adjusting rod 3 fixes the manhole cover on the placement table 6. In summary, when fixing the manhole cover, it is only necessary to drive the motor 405, and the operation is relatively convenient. At the same time, since the driving screw 401 and the adjusting rod 3 are threaded together, the stability of the clamping assembly 5 after the manhole cover is fixed under the drive of the adjusting rod 3 can be guaranteed; 2. When the inner wall of the arc frame 501 contacts the outer side of the manhole cover, the arc frame is stopped. The driving of 501, and then the adjusting screw 502 is rotated through the control ring 506, so that the adjusting screw 502 drives the clamping plate 503 to move downward and the clamping plate 503 cooperates with the bottom inner wall of the arc frame 501 to fix the manhole cover up and down. The cooperation of multiple arc frames 501 can clamp and fix the manhole cover, and the clamping plate 503 can fix the upper and lower sides of the manhole cover, thereby improving the stability of the manhole cover during testing; 3. When the adjusting rod 3 moves, it can drive the roller 10 to rotate at the bottom of the inner wall of the support box 1. The setting of the roller 10 enables the adjusting rod 3 to better support the manhole cover through the arc frame 501, and at the same time, the friction between the adjusting rod 3 and the bottom of the inner wall of the support box 1 is small when moving.
