Description

Technical Field

[0001] This utility model belongs to the field of precast concrete column production and maintenance technology, specifically relating to a water spraying device for precast concrete column maintenance. Background Technology

[0002] Precast concrete columns are column components that are prefabricated in a factory or on-site, primarily using steel reinforcement and concrete as basic materials. Precast columns are cast and shaped in a factory or on-site, and used in construction projects after reaching the required strength. Precast concrete columns have high production efficiency, which can significantly shorten the construction period and reduce construction costs.

[0003] After precast concrete columns are produced, they need to be cured regularly to ensure quality. The conventional method is water spraying. However, existing water spraying devices directly spray water onto the precast columns placed on the ground. This results in the side of the column in contact with the ground being difficult to wet, affecting the effectiveness of water curing. Furthermore, the sprayed water runs off the ground, causing not only water loss but also creating a muddy working environment, negatively impacting the work environment. Utility Model Content

[0004] The purpose of this utility model is to provide a water spraying device for curing precast concrete columns, so as to solve the problem mentioned in the background art that the existing water spraying devices directly spray the nozzles onto the precast columns placed on the ground. This makes it difficult for the side of the precast column in contact with the ground to be wetted with water, which affects the water spraying curing effect. Moreover, the water sprayed out will flow near the ground, which not only causes water loss, but also makes the working environment muddy and affects the working environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water spraying device for curing precast concrete columns, comprising a frame, a water tank installed below the frame, a water receiving hopper fixedly installed on the upper surface of the water tank, a filter screen detachably installed at the bottom of the water receiving hopper, a water pump fixedly installed on the side of the water tank, two fixing frames 1 provided above the frame, the lower fixing frame 1 fixedly installed on the upper surface of the frame, and the upper fixing frame 1 movably installed above the frame, and cylinder 1 and cylinder 2 fixedly installed on the side of the frame, the piston rod end of cylinder 1 being connected to the upper fixing frame 1. A fixed connection is provided, wherein a fixed frame 2 is fixedly installed at the end of the piston rod of the cylinder 2, the fixed frame 2 is located between two fixed frames 1, and two flat plates are provided inside the fixed frame 1. Each of the two flat plates has a receiving groove on its opposite surface, and an arc-shaped plate is movably installed in the receiving groove. Sliders are fixedly installed on both ends of the flat plates. A slide rail for sliding the slider is provided on the side of the fixed frame 1. A water pipe is fixedly installed on the inner wall of the fixed frame 1. Several nozzles and a telescopic pipe are installed on the water pipe. The telescopic pipe is connected to the outlet of the water pump, and the inlet of the water pump extends into the water tank.

[0006] The above solution utilizes two fixed frames, Frame 1 and Frame 2, which are respectively fixed and movable. This allows the precast column to be placed vertically. The flat and curved clamping plates within Frame 1 secure the column, while Frame 2's vertical movement, combined with the spray nozzles, ensures comprehensive water spraying for curing the precast column surface. This prevents the column from being left lying on the ground, where the side in contact with the ground is difficult to wet, thus improving the water distribution and curing effect. The flat and curved clamping plates can be switched, making it suitable for fixing and securing precast columns of different shapes, enhancing its versatility. A filter screen is used in conjunction with the water tank; the water sprayed from the nozzles flows downwards through the water collection basin and is filtered by the filter screen, preventing water loss and ensuring water recycling. The filter screen is also detachable for easy cleaning of residue.

[0007] In the above scheme, it should be noted that cylinder one, cylinder two and water pump are all electrically connected to an external power supply.

[0008] In a preferred embodiment, a support frame is fixedly installed on the inner wall of the water receiving hopper, the filter screen is attached to the surface of the support frame, and a number of fixing bolts are threaded between the filter screen and the support frame.

[0009] The above solution uses a support frame to support the filter screen and uses fixing bolts to lock the filter screen in place. The locking structure is simple, easy to disassemble, and prevents the filter screen from shifting or shaking, thus improving the stability of the filter screen in use.

[0010] In a preferred embodiment, a plurality of guide rods are fixedly installed on the upper surface of the frame, and the top of the plurality of guide rods is fixedly installed with the same guide frame. A plurality of guide sleeves are fixedly installed on the side of the fixed frame and on the side of the fixed frame at the upper position, and the guide sleeves are slidably installed on the outer surface of the guide rods at the corresponding positions.

[0011] Using the above scheme, the guide sleeve slides on the surface of the guide rod, which can ensure good stability of the vertical movement of the fixed frame 1 and the fixed frame 2. The guide frame can support and guide multiple guide rods 1, thereby improving the structural stability.

[0012] In a preferred embodiment, two fixing blocks are fixedly installed on the side of the fixing frame, one of which is fixedly mounted with a motor, and a bidirectional screw is rotatably installed between the two fixing blocks. Two sliders on the same side of the two planar plates are respectively threaded onto the outer surfaces of the two threads of the bidirectional screw.

[0013] Using the above scheme, a motor drives a bidirectional screw to rotate, which in turn drives two planar clamping plates to move relative to each other via a slider, thereby achieving the clamping and fixing of the precast column.

[0014] In a preferred embodiment, a limiting rod is fixedly installed on the inner wall of the upper slide of the fixed frame, and the slider is slidably installed on the outer surface of the limiting rod at the same side position.

[0015] By adopting the above solution, the setting of the limit rod can ensure that the slider can slide stably and will not tilt.

[0016] In a preferred embodiment, an adjusting plate is slidably mounted on the flat plate opposite the receiving groove. A linkage plate is fixedly mounted on one end of the adjusting plate. An adjusting bolt is threaded onto the flat plate. Two adjusting threaded grooves are provided on the adjusting plate for the adjusting bolt to be screwed into. A guide rod is fixedly mounted on the side of the flat plate. The linkage plate is slidably mounted on the outer surface of the guide rod. A spring is fixedly mounted between the linkage plate and the flat plate.

[0017] Using the above scheme, the position of the curved plate can be adjusted by using the adjusting plate in conjunction with the adjusting bolt. The second guide rod can guide and support the movement of the linkage plate, improving the smoothness of the movement. When the curved plate is stored in the receiving groove on the flat plate, the spring is in a deformed state. Therefore, after the adjusting bolt is unscrewed, the elastic force of the spring can be used to quickly drive the curved plate out of the flat plate, improving the convenience of operation and adjustment.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This water spraying device for curing precast concrete columns uses two fixed frames: a first fixed frame and a second fixed frame. The first fixed frame is fixed and movable, allowing the precast column to be placed vertically. The flat and curved clamping plates within the first fixed frame are used to clamp the precast column. The second fixed frame moves up and down in conjunction with the nozzles to spray water, achieving comprehensive water spraying and curing of the precast column surface. This avoids the problem of the precast column being placed on the ground and the side in contact with the ground being difficult to wet, thus improving the water distribution and curing effect. Furthermore, the flat and curved clamping plates can be switched, making it suitable for fixing and clamping precast columns of different shapes, thus improving its versatility.

[0020] This water spraying device for curing precast concrete columns uses a filter screen in conjunction with a water tank. The water sprayed from the nozzles flows downwards and passes through a water collection hopper to filter the water, preventing water loss and ensuring the recycling of water resources. The filter screen is also designed to be detachable for easy cleaning of residues. Attached Figure Description

[0028] Please see Figure 1-6This utility model provides a water spraying device for curing precast concrete columns, including a frame 1, a water tank 2 installed below the frame 1, a water receiving hopper 3 fixedly installed on the upper surface of the water tank 2, a filter screen 4 detachably installed at the bottom of the water receiving hopper 3, a water pump 5 fixedly installed on the side of the water tank 2, two fixing frames 6 provided above the frame 1, the lower fixing frame 6 fixedly installed on the upper surface of the frame 1, and the upper fixing frame 6 movably installed above the frame 1, a cylinder 7 and a cylinder 8 fixedly installed on the side of the frame 1, the piston rod end of the cylinder 7 being fixedly connected to the upper fixing frame 6, and the piston rod end of the cylinder 8 being fixedly connected to the upper fixing frame 6. A fixing frame 2 9 is fixedly installed at the end of the plunger rod. The fixing frame 2 9 is located between two fixing frames 1 6. Two flat plates 11 are provided inside the fixing frame 1 6. Each of the two flat plates 11 has a receiving groove on its opposite side. An arc plate 12 is movably installed in the receiving groove. Slider 10 is fixedly installed on both ends of the flat plates 11. A slide rail for sliding the slider 10 is provided on the side of the fixing frame 1 6. A water pipe 13 is fixedly installed on the inner wall of the fixing frame 1 6. Several nozzles 14 and a telescopic pipe 15 are installed on the water pipe 13. The telescopic pipe 15 is connected to the outlet of the water pump 5. The inlet of the water pump 5 extends into the water tank 2.

[0029] By using fixed frame 6 and fixed frame 9 together, with fixed and movable fixed frames 6 respectively, the precast column can be placed vertically. The flat plate 11 and curved plate 12 inside the fixed frame 6 are used to clamp the precast column. The up and down movement of the fixed frame 9, combined with the spray nozzle 14, sprays water to achieve full water curing of the surface of the precast column. This avoids the precast column being difficult to wet on the side in contact with the ground when it is placed on the ground, thus improving the water curing effect. The flat plate 11 and curved plate 12 can be switched to be used to fix and clamp precast columns of different shapes, improving the versatility of use. By setting up a filter screen 4 to work with the water tank 2, the water sprayed from the nozzle 14 flows downward and passes through the water receiving hopper 3 and is filtered by the filter screen 4 to prevent water loss and ensure the recycling of water resources. The filter screen 4 is detachable for easy cleaning of residue.

[0030] A support frame 16 is fixedly installed on the inner wall of the water receiving hopper 3. The filter screen 4 is attached to the surface of the support frame 16. Several fixing bolts 17 are threaded between the filter screen 4 and the support frame 16. The support frame 16 supports the filter screen 4, and the fixing bolts 17 are used to lock the filter screen 4 in place. The locking structure is simple and easy to disassemble, which prevents the filter screen 4 from moving or shaking and improves the stability of the filter screen 4 in use.

[0031] Several guide rods 18 are fixedly installed on the upper surface of the frame 1. The top of the guide rods 18 is fixedly installed with the same guide frame 19. Several guide sleeves 20 are fixedly installed on the side of the fixed frame 2 9 and the side of the fixed frame 6 above it. The guide sleeves 20 are slidably installed on the outer surface of the guide rods 18 at the corresponding positions. The sliding of the guide sleeves 20 on the surface of the guide rods 18 can ensure good stability of the vertical movement of the fixed frame 6 and the fixed frame 2 9. The guide frame 19 can support and guide the multiple guide rods 18, thereby improving the structural stability.

[0032] Two fixing blocks 21 are fixedly installed on the side of the fixing frame 6. A motor 22 is fixedly installed on one of the fixing blocks 21. A bidirectional screw 23 is rotatably installed between the two fixing blocks 21. Two sliders 10 on the same side of the two flat clamping plates 11 are respectively threaded onto the two threaded outer surfaces of the bidirectional screw 23. The motor 22 drives the bidirectional screw 23 to rotate, thereby driving the two flat clamping plates 11 to move relative to each other through the sliders 10, so as to achieve the clamping and fixing of the precast column.

[0033] A limiting rod 24 is fixedly installed on the inner wall of the upper slide of the fixed frame 6. The slider 10 is slidably installed on the outer surface of the limiting rod 24 at the same side position. The setting of the limiting rod 24 can ensure that the slider 10 can slide stably and will not tilt.

[0034] An adjusting plate 25 is slidably mounted on the flat plate 11, directly opposite the receiving groove. A linkage plate 26 is fixedly mounted on one end of the adjusting plate 25. An adjusting bolt 27 is threaded onto the flat plate 11. The adjusting plate 25 has two adjusting threaded grooves for the adjusting bolt 27 to be screwed into. A guide rod 28 is fixedly mounted on the side of the flat plate 11. The linkage plate 26 is slidably mounted on the outer surface of the guide rod 28. A spring 29 is fixedly mounted between the linkage plate 26 and the flat plate 11. By using the adjusting plate 25 in conjunction with the adjusting bolt 27, the position of the curved plate 12 can be adjusted. The guide rod 28 can guide and support the movement of the linkage plate 26, improving the smoothness of movement. When the curved plate 12 is stored in the receiving groove on the flat plate 11, the spring 29 is in a deformed state. Therefore, after the adjusting bolt 27 is unscrewed, the elastic force of the spring 29 can quickly drive the curved plate 12 out of the flat plate 11, improving the convenience of operation and adjustment.

[0035] In use, first adjust the position of the fixed frame 6 at the top according to the overall length of the precast column. During adjustment, start cylinder 7. Cylinder 7 extends and retracts, driving the fixed frame 6 to move up and down. After adjusting to the appropriate height, stop cylinder 7. Hoist the precast column through the two fixed frames 6 and the second fixed frame 9 and keep it vertical. Then, select the flat clamping plate 11 or the curved clamping plate 12 according to whether the surface of the precast column is flat or curved. The initial state is flat clamping plate 11. When the curved clamping plate 12 needs to be used, unscrew the adjusting bolt 27. At this time, the curved clamping plate 12 will move out of the flat clamping plate 11 under the action of spring 29. Then screw in the adjusting bolt 27 to lock it. At this time, the curved clamping plate 12 protrudes from the flat clamping plate 11. Then, the motor 22 is started to drive the bidirectional screw 23 to rotate, which in turn drives the slider 10 to move the flat clamping plate 11. The flat clamping plate 11 or the arc clamping plate 12 is used to clamp and fix the precast column. After it is fixed, the water pump 5 and the cylinder 8 are started. The water pump 5 draws water from the water tank 2 and delivers it to the nozzle 14 through the telescopic pipe 15 and the water pipe 13. The nozzle 14 sprays water toward the surface of the precast column to achieve water curing. At the same time, the cylinder 8 extends and retracts to drive the fixed frame to move up and down to achieve comprehensive water curing. The sprayed water flows down into the water receiving hopper 3, and after the filter screen 4 filters out the residue, it enters the water tank 2. When it is necessary to clean the filter screen 4, the fixing bolt 17 is unscrewed to release the lock of the filter screen 4, and then the filter screen 4 can be disassembled for cleaning.
