Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of bridge pier maintenance technology, and more specifically, to a bridge pier spray maintenance device. Background Technology

[0002] Spray curing of bridge piers can reduce the surface temperature of concrete, slow down the shrinkage rate of concrete over time, and promote early strength development and crack resistance. While existing methods of spraying bridge piers with water pipes are convenient, they cannot effectively cure the upper parts of the piers. Furthermore, most existing bridge pier curing devices can only spray one side of the pier at a time, requiring disassembly and relocation to the other side for further spraying. This increases installation and disassembly workload and reduces curing efficiency. Therefore, to address these technical problems, this paper proposes a bridge pier curing device that sprays along the entire length of the pier. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a bridge pier spray curing device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a bridge pier column spraying maintenance device, including a spraying device installed on the outside of the bridge pier column, a spraying device support frame for supporting the spraying device, and a water supply component for supplying water to the spraying device.

[0027] like Figure 1-6 As shown, this utility model provides a bridge pier column spraying maintenance device, including a spraying device 3 installed on the outside of the bridge pier column 5, a spraying device support frame 1 for supporting the spraying device 3, and a water supply component 4 for supplying water to the spraying device 3. A spraying device adjustment mechanism 2 is provided between the spraying device support frame 1 and the spraying device 3. The spraying device adjustment mechanism 2 includes a fixed column 21, an adjustment arm 22 located at the top of the fixed column 21, a telescopic arm 23 located inside the adjustment arm 22, a hydraulic push rod 24, and a hook 26 connected to the spraying device 3. The spraying device 3 includes a top plate 31, a plurality of splicing blocks 32, a spray head 33 located inside the splicing blocks 32, and a push rod 34 provided between the top plate 31 and the splicing blocks 32.

[0028] Furthermore, in this embodiment, the rear end of the adjusting arm 22 is movably connected to the top of the fixed column 21. A connecting plate 27 is provided between the top of the fixed column 21 and the rear end of the adjusting arm 22. The fixed column 21 and the adjusting arm 22 are rotatably connected to the connecting plate 27. The connecting plate 27 is a steel plate. The adjusting arm 22 and the fixed column 21 are connected together through the connecting plate 27. The rear end of the adjusting arm 22 is arc-shaped, so that it can rotate against the top side of the fixed column 21.

[0029] It should be noted that the adjusting arm 22 and the fixed column 21 are connected to the connecting plate 27 by bolts, and the bolts can be of a common type available on the market.

[0030] In this embodiment, a hydraulic push rod 24 is provided on the upper and lower surfaces of the adjusting arm 22. The hydraulic push rod 24 on the upper surface is horizontally placed on the upper surface of the adjusting arm 22, and its telescopic end is bolted to the outer end of the telescopic arm 23. The horizontally placed hydraulic push rod 24 is used to control the advancement and retraction of the telescopic arm 23 connected to it synchronously. The hydraulic push rod 24 on the lower surface is vertically placed on one side of the fixed column 21. Its telescopic end is bolted to the lower surface of the adjusting arm 22, and its bottom is bolted to the fixed column 21. The use angle of the adjusting arm 22 is controlled by the raising and lowering of the vertically placed hydraulic push rod 24. That is, when the hydraulic push rod 24 rises, the adjusting arm 22 will be lifted from the normal horizontal state, the angle between the adjusting arm 22 and the fixed column 21 will increase, the rear end of the adjusting arm 22 will be lifted, and the front end will tilt downward. The same applies to the opposite. The two hydraulic push rods 24 are used to adjust the use position of the spray device 3 installed on the spray device adjustment mechanism 2.

[0031] It should be noted that the two hydraulic push rods 24 are independently controlled in steps.

[0032] In this embodiment, the adjusting arm 22 is sleeved on the outside of the telescopic arm 23, and the telescopic arm 23 is slidably connected to the adjusting arm 22. A fixing block 25 is fixed at the front end of the telescopic arm 23, and a hook 26 connected to the spray device 3 is fixed below the fixing block 25. The telescopic arm 23 slides inside the adjusting arm 22 to extend and retract, and the fixing block 25 at its end moves synchronously, so that the spray device 3 connected through the hook 26 also moves along with it.

[0033] In this embodiment, the shape of the spray device 3 is adapted to the shape of the bridge pier 5. A lifting ring 35 that is hooked to the hook 26 is fixed at the center of the upper surface of the top plate 31. The spray device 3 is connected to the hook 26 through the lifting ring 35. An inner conduit 321 is provided inside the splicing block 32. The input end of the spray head 33 is connected to the inner conduit 321. The inner conduit 321 is pre-fixed in the splicing block 32. Water is introduced into the spray head 33 through the inner conduit 321.

[0034] It should be noted that in windy weather, the connection between the single lifting ring 35 and the hook 26 may sway. Therefore, in windy weather, choose the hook 26 and lifting ring 35 that are sealed at the factory to prevent the lifting ring 35 from coming off the hook.

[0035] In this embodiment, the number of push rods 34 is the same as the number of splicing blocks 32. Considering that the bridge pier 5 needs to be sprayed comprehensively, the number of spray heads 33 must ensure the coverage of the spray. The two ends of the push rods 34 are screwed to the splicing blocks 32 and the top plate 31 respectively. The push rods 34 are either electric push rods 34 or hydraulic push rods 24. The electric push rods 34 or hydraulic push rods 24 are selected according to the spray intensity. The push rods 34 on the top plate 31 advance and retract synchronously. The splicing blocks 32 with spray heads 33 are controlled by the push rods 34 to move up and down outside the bridge pier 5 for spraying. Push rods 34 with built-in waterproof measures are selected to reduce the possibility of water damage.

[0036] In this embodiment, splicing blocks 32 are selected according to the size or shape of the bridge pier 5 for splicing. At least two connectors 36 are provided between adjacent splicing blocks 32. The connectors 36 include a connecting post 361 fixed on the right side of the splicing block 32. A connecting hole 362 adapted to the connecting post 361 is opened on the left side of the connecting post 361. Adjacent splicing blocks 32 are connected by inserting the connecting post 361 into the connecting hole 362. The initial splicing is carried out by the cooperation of the connecting post 361 and the connecting hole 362.

[0037] In this embodiment, a screw 363 is provided between the connecting post 361 and the splicing block 32. Both the connecting post 361 and the splicing block 32 have through holes 364 adapted to the screw 363. The screw 363 passes through the splicing block 32 and the connecting post 361 through the through holes 364 and is threaded with both. The connecting post 361 is fixed in the connecting hole 362 by the screw 363, thereby connecting and fixing the adjacent splicing blocks 32.

[0038] It should be noted that when splicing the splicing block 32, the internal conduits 321 need to be aligned, and the two ends of the internal conduits 321 are designed to be one large and one small, with the small end protruding a portion. The small ends of adjacent internal conduits 321 are inserted into the large ends for connection, and the splicing joints of the internal conduits 321 need to be sealed, for example, by setting a sealing rubber ring at the connection, to prevent water leakage when the splicing block 32 is used.

[0039] In this embodiment, the spray device support frame 1 includes a support platform 11 disposed at the bottom of the fixed column 21, crossbars 12 installed at the four corners of the support platform 11 by screws, and hydraulic support legs 13 for support. The hydraulic support legs 13 are screwed to the outer end of the crossbars 12. The support platform 11 supports the spray device adjustment mechanism 2. The crossbars 12 connect the hydraulic support legs 13 to the support platform 11, and the hydraulic support legs 13 support the support platform 11.

[0040] In this embodiment, two support frames 14 are provided at the bottom of the support platform 11. The support frames 14 are U-shaped and are screwed to the support platform 11. They are also framed on the outside of the crossbar 12. The support frames 14 reinforce the crossbar 12 and improve the stability of the spray device support frame 1.

[0041] Specifically, during the curing period after the concrete of bridge pier 5 is poured, the process of spraying using a spray curing device is as follows:

[0042] Confirm the size, shape (round / square / irregular) and height of the bridge pier 5, select the appropriate number of splicing blocks 32 and the specifications of the sprinkler device 3, and check whether there are any obstacles on the surface of the pier (such as exposed steel bars or debris), which need to be cleaned in advance.

[0043] Select splicing block 32 according to the shape of the pier column, and initially splice it by inserting the connecting column 361 into the connecting hole 362, and then fix it through with screw 363. Ensure that the inner guide tube 321 is aligned (small end inserted into large end), use sealing rubber rings at the connection to prevent water leakage, connect the sprinkler head 33 to the inner guide tube 321, and test the sealing performance of splicing block 32 (check for leakage by running water).

[0044] Place the support platform 11 on a flat ground next to the bridge pier 5, fix the crossbar 12 to the four corners of the support platform 11 with bolts, install the hydraulic outriggers 13 to the outer end of the crossbar 12, adjust the height of the outriggers to make the support platform 11 horizontal (it needs to be calibrated with a level), and use the U-shaped support frame 14 to reinforce the connection between the crossbar 12 and the support platform 11.

[0045] Connect the water supply component 4 (water pump 42 for conveying water, water tank 41 for providing water source, and water supply pipe 43 for guiding water, wherein the water supply pipe 43 is a stretchable hose that rises and falls synchronously with the splicing block 32 after it is assembled, and is stretched or retracted) to the inlet of the inner conduit 321 of the sprinkler device 3 (after the splicing block 32 is assembled, select the splicing block 32 closest to the side of the water supply component 4 to connect the water source, and connect the outlet of the water supply pipe 43 to the inner conduit 321 of the splicing block 32. Since the inner conduit 321 of each splicing block 32 is connected, water can be supplied to each sprinkler head 33), turn on the water pump 42, check whether the sprinkler head 33 is discharging water evenly, and remove any blockages;

[0046] Hang the lifting ring 35 of the spray device 3 on the hook 26 of the telescopic arm 23, adjust the height of the hook 26 so that the top plate 31 of the spray device 3 is 10-20cm higher than the top of the pier, so that the push rod 34 can be deployed later. Start the horizontal hydraulic push rod 24 to push the telescopic arm 23 to extend so that the center of the spray device 3 is aligned with the center of the pier. Start the vertical hydraulic push rod 24 to raise the adjusting arm 22 until the spray device 3 is parallel to the surface of the pier.

[0047] Synchronously start all push rods 34 (electric push rods 34 or hydraulic push rods 24) on the top plate 31, and place the spray head 33 of the splicing block 32 20-30cm away from the surface of the pier (this distance needs to be determined when selecting the size of the splicing block 32 in advance; it needs to be changed for piers of different diameters / shapes, different water pressures, and different nozzle models). Check whether the waterproof sleeve of the push rod 34 is intact to avoid water ingress and short circuit. Set the spraying time, such as spraying for 10 minutes and pausing for 5 minutes (to avoid water accumulation on the surface of the pier). Turn on the water pump 42 of the water supply component 4 and observe whether the spray head 33 fully covers the pier (pay special attention to the splicing joint). Control the push rod 34 to gradually raise and lower to spray the bridge pier 5 (pause every 1m increase to check the uniformity of spraying).

[0048] After the spraying maintenance is completed, first turn off the water pump 42, then retract the push rod 34 to its shortest position to avoid bumping the spray head 33, drain the water accumulated in the inner conduit 321 and water pipe (to prevent freezing and cracking), disassemble the water supply pipe 43, retract the hydraulic support leg 13, lower the height of the support platform 11, and use the hook 26 to transfer the spraying device 3 to the ground. Disassemble the splicing block 32 and support frame in sequence and store them separately (the splicing block 32 needs to be marked with a number for easy quick reassembly next time).

[0049] If this occurs, immediately shut off the water pump 42, check if the sealing ring of the inner conduit 321 of the splicing block 32 has come off, retighten the screw 363, and if the spray head 33 is blocked, remove the spray head 33 and clear it with a fine needle (the valve of the branch water pipe must be closed first).

[0050] It is worth noting that the control method in this application is to control the activation of devices such as hydraulic push rod 24 and water pump 42 through a controller. The controller is a conventional PLC or relay logic control. The electromagnetic reversing valve of the hydraulic push rod and the start / stop contactor of the water pump are driven by 24V switching signals. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. This application will not explain the control method and circuit connection in detail.
