After passing the detection, a concrete cushion can be poured on the foundation, and the support is erected on the top of the concrete cushion to disperse the load of the cast-in-place box girder upper structure. The strength, stiffness, stability of the temporary support and the force on the foundation play a crucial role in bridge construction.

[0003] During the use of bridge supports, it is necessary to preload the supports.

Detailed Embodiments

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] Such as Figures 1 to 7As shown in the figure, a temporary support preloading device according to an embodiment of the present invention includes a transport vehicle body 1; a transport vehicle compartment is rotatably connected to the top of the transport vehicle body 1; a transport vehicle head 2 is fixedly connected to the side wall of the transport vehicle body 1; a hydraulic component is installed inside the transport vehicle body 1, and the hydraulic component can push and tilt the transport vehicle compartment of the transport vehicle body 1; two driving wheels 3 are installed at the bottom of the transport vehicle body 1; the rotation of the driving wheels 3 is driven by a motor; a steering wheel 4 is installed at the bottom of the transport vehicle head 2; a rotating rod is fixedly connected to the top of the steering wheel 4; a servo motor is installed at the top of the transport vehicle head 2; the end of the rotating rod is fixedly connected to the output end of the servo motor; a motor cover 5 is provided to cover the top of the transport vehicle head 2; a storage box body 6 is fixedly connected to the inside of the transport vehicle compartment through a fixing bolt 8; a storage box cover 7 is installed on the top of the storage box body 6; a fixing knob is threadedly connected to the side wall of the storage box body 6, and the fixing knob is arranged at a position corresponding to the storage box cover 7; a preloading water bag 9 is placed inside the storage box body 6; a connecting component is provided on the side wall of the preloading water bag 9, and the connecting component can fix the preloading water bag 9 on the side wall of the storage box body 6; a water injection pipe 11 is provided on the side wall of the storage box body 6; the end of the water injection pipe 11 is connected to the inside of the storage box body 6; a opening and closing door 10 is slidably connected to the side wall of the storage box body 6; an electric push rod is installed on the side wall of the transport vehicle body 1; the output end of the electric push rod is fixedly connected to a pushing rod 101; the end of the pushing rod 101 is fixedly connected to the opening and closing door 10; during operation, when it is necessary to preload the temporary support of the bridge, the driving wheels 3 can be driven by the motor to move the transport vehicle body 1. During the movement, since no water is injected into the preloading water bag 9, the weight of the preloading water bag 9 is relatively light. After the transport vehicle body 1 moves to the position where the preloading water bag 9 needs to be placed, water can be injected into the bottommost preloading water bag 9 through the water injection pipe 11. When the preloading water bag 9 is filled with water, the opening and closing door 10 can be pulled by the electric push rod to open the opening and closing door 10. After the opening and closing door 10 is fully opened, the transport vehicle compartment can be pushed and tilted by the hydraulic component, thereby driving the storage box body 6 to tilt, so that the preloading water bag filled with water 9 falls by gravity, and the remaining preloading water bags 9 are stuck by the connecting component and will not flow out together with the bottommost preloading water bag 9. After the preloading water bag 9 filled with water is poured out, the transport vehicle body 1 can be driven to reset by the hydraulic component, and then the opening and closing door 10 can be closed and continue to move to the next placement point. During the movement, the rotating rod is driven to rotate by the servo motor, and then the steering wheel 4 is driven to rotate, which can drive the transport vehicle body 1 to turn, so that the transport vehicle body 1 can better move to the position where the preloading water bag 9 needs to be arranged. At the same time, the preloading water bag 9 is transported by the transport vehicle body 1, which can effectively reduce the loss of manpower.

[0032] As Figures 3 to 5As shown, the connecting assembly includes a connecting block 12; the connecting block 12 is fixedly connected to the side wall of the pre-pressurized water bag 9; a water injection through hole is provided inside the connecting block 12, and the water injection through hole is connected to the inside of the pre-pressurized water bag 9; a positioning block 14 is fixedly connected to the side wall of the connecting block 12; a positioning groove 13 is provided on the side wall of the storage box 6; the positioning groove 13 is provided on the side wall of the storage box 6 away from the closing door 10; a second magnetic block 16 is fixedly connected to the side wall of the connecting block 12; a first magnetic block 15 is fixedly connected to the side wall of the positioning groove 13; the first magnetic block 15 is arranged at a position corresponding to the end of the water injection pipe 11; during operation, when the pre-pressurized water bag 9 is in the storage box 6 When the pre-pressurized water bag 9 is arranged internally, the positioning block 14 is restricted by the positioning groove 13, which can make the pre-pressurized water bag 9 better arranged inside the storage box 6. When the pre-pressurized water bag 9 moves to the position corresponding to the water injection pipe 11, the positioning block 14 will disengage from the positioning groove 13, and the first magnetic block 15 will attract the second magnetic block 16, so that the end of the connecting block 12 can be tightly attached to the end position of the water injection pipe 11, so that the water injection pipe 11 can better inject water into the interior of the pre-pressurized water bag 9. After the water filling is completed, the transport box will tilt, and then the pre-pressurized water bag 9 will fall due to gravity, so that the first magnetic block 15 and the second magnetic block 16 can be disengaged, so that the pre-pressurized water bag 9 can be separated from the interior of the storage box 6.

[0033] like Figure 5 As shown, a sealing ball 17 is provided inside the pre-pressurized water bag 9; the side wall of the sealing ball 17 is in contact with the side wall of the water injection hole; a plurality of elastic ropes 18 are connected between the sealing ball 17 and the water injection hole; during operation, when water is injected into the pre-pressurized water bag 9 through the water injection pipe 11, the water flow will push the sealing ball 17 during the injection process, thereby allowing the water flow to flow into the pre-pressurized water bag 9. After the water flow enters the pre-pressurized water bag 9, the sealing ball 17 will block the water injection hole, effectively preventing the water inside the pre-pressurized water bag 9 from flowing out of the pre-pressurized water bag 9.

[0034] like Figure 3 As shown, a pushing block 19 is provided at the bottom of the storage box cover 7; a spring is fixed between the pushing block 19 and the bottom side wall of the storage box cover 7; a positioning block 14 is fixed to the side wall of the pushing block 19; the positioning block 14 is slidably connected to the inside of the positioning groove 13; the pushing block 19 is arranged at the position corresponding to the connecting block 12; during operation, when the connecting block 12 slides inside the storage box body 6, the elastic force of the spring will push the pushing block 19, and then the pushing block 19 will push the connecting block 12 to slide downward, thereby effectively avoiding the influence of friction, which may cause the connecting block 12 to get stuck.

[0035] like Figure 5As shown, the bottom of the connecting block 12 and the pushing block 19 are fixedly connected with an anti-slip block 20; the top of the connecting block 12 is provided with an anti-slip groove 21; the anti-slip block 20 and the anti-slip groove 21 are arranged correspondingly; during operation, when the pushing block 19 pushes the connecting block 12, the anti-slip block 20 at the bottom of the connecting block 12 will be stuck in the anti-slip groove 21 of the bottom connecting block 12, thereby increasing the friction between the two connecting blocks 12, so that the pre-pressurized water bag 9 can be placed more stably inside the storage box 6.

[0036] like Figure 1 and Figure 6 As shown, a deflector 22 is provided on the side wall of the transport box away from the transport head 2; a fixing pin 25 is fixedly connected to the side wall of the deflector 22 close to the transport box; a pin slot is provided on the side wall of the transport box, and the pin slot is provided at the position corresponding to the fixing pin 25; a plurality of deflector slots 23 are provided on the top of the deflector 22; a pull rope 24 is fixedly connected to the top of the deflector 22; a fixing gasket is fixed to the side wall of the transport box by bolts; during operation, before the transport body 1 is started, the fixing gasket can be used The fixed bolt 8 fixes the fixing pin 25 inside the pin groove and fixes the fixing gasket on the side wall of the transport box. Then, when the transport box is tilted and the pre-pressurized water bag 9 filled with water in the storage box 6 is poured out, the guide plate 22 can guide the pre-pressurized water bag 9, so that the pre-pressurized water bag 9 can better fall to the position where the pre-pressurized water bag 9 needs to be arranged. At the same time, the guide groove 23 can make the contact area between the pre-pressurized water bag 9 and the guide plate 22 larger, thereby effectively avoiding the pre-pressurized water bag 9 from being deflected during the falling process, so that the landing point of the pre-pressurized water bag 9 can be more accurate.

[0037] like Figure 7 As shown, the opening and closing door 10 is internally connected to a plurality of anti-wear wheels 26 for rotation; the side walls of the anti-wear wheels 26 are in contact with the side walls of the storage box 6; during operation, when the opening and closing door 10 slides inside the storage box 6, the anti-wear wheels 26 roll, so that the sliding friction between the opening and closing door 10 and the storage box 6 can be converted into rolling friction, thereby making the friction between the opening and closing door 10 and the storage box 6 smaller, and reducing the wear between the storage box 6 and the opening and closing door 10.

[0038] like Figure 3 As shown, a rubber pad 27 is fixed to the side wall of the storage box cover 7; the rubber pad 27 is arranged at the position corresponding to the fixed knob; during operation, when the fixed knob fixes the storage box cover 7, by arranging the rubber pad 27 on the side wall of the storage box cover 7, the contact area between the storage box cover 7 and the fixed knob can be made larger, thereby making the friction between the storage box cover 7 and the fixed knob larger, so that the fixing effect of the fixed knob on the storage box cover 7 is better.

[0039] As Figure 7 shown, a plurality of positioning rods 28 are fixedly connected to the top of the opening and closing door 10; the positioning rods 28 are slidably connected inside the storage box body 6; during operation, when the opening and closing door 10 slides inside the storage box body 6, through the restriction of the storage box body 6 by the positioning rods 28, the opening and closing door 10 can be made to tilt less during the sliding process, making the sliding of the opening and closing door 10 more stable.

[0040] As Figure 8 shown, a sliding plate 29 is slidably connected inside the fixing bolt 8; a connecting rod 30 is fixedly connected to the bottom of the sliding plate 29; a contact block 31 is fixedly connected to the end of the connecting rod 30; a spring is fixedly connected between the side wall of the sliding plate 29 on the side away from the connecting rod 30 and the inner side wall of the fixing bolt 8; during operation, when using the fixing bolt 8 for fixing, during the process of screwing the fixing bolt 8 into the threaded hole, the contact block 31 will first contact the bottom of the threaded hole, and then continue to screw in the fixing bolt 8. By the extrusion of the spring on the sliding plate 29, the friction between the fixing bolt 8 and the threaded hole can be made greater, so that the fixing effect of the fixing bolt 8 can be better.

[0041] During operation, when it is necessary to preload the temporary support of the bridge, the driving wheel 3 can be driven by the motor to move the transport vehicle body 1. During the movement, since no water is injected into the preloading water bag 9, the weight of the preloading water bag 9 is relatively light. After the transport vehicle body 1 moves to the position where the preloading water bag 9 needs to be placed, water can be injected into the bottommost preloading water bag 9 through the water injection pipe 11. When the preloading water bag 9 is filled with water, the opening and closing door 10 can be pulled by the electric push rod to open the opening and closing door 10. After the opening and closing door 10 is fully opened, the transport vehicle box can be tilted by the hydraulic component, and then the storage box body 6 can be driven to tilt, so that the preloading water bag 9 filled with water falls by gravity, and the remaining preloading water bags 9 are stuck by the connecting component and will not flow out together with the bottommost preloading water bag 9. After the preloading water bag 9 filled with water is poured out, the transport vehicle body 1 can be driven to reset by the hydraulic component, and then the opening and closing door 10 can be closed and continue to move to the next placement point. During the movement, the rotating rod is driven to rotate by the servo motor, and then the steering wheel 4 is driven to rotate, which can drive the transport vehicle body 1 to turn, so that the transport vehicle body 1 can move better to the position where the preloading water bag 9 needs to be arranged. At the same time, by using the transport vehicle body 1 to carry the preloading water bag 9, the loss of manpower can be effectively reduced.

[0042] When the pre-pressure water bag 9 is arranged inside the storage box 6, through the restriction of the positioning block 14 by the positioning groove 13, the arrangement effect of the pre-pressure water bag 9 inside the storage box 6 can be better. After the pre-pressure water bag 9 moves to the position corresponding to the water injection pipe 11, the positioning block 14 will disengage from the positioning groove 13, and the first magnet 15 will attract the second magnet 16, so that the end of the connecting block 12 can closely adhere to the end of the water injection pipe 11, enabling the water injection pipe 11 to inject water into the pre-pressure water bag 9 better. After the water injection is completed, the transport vehicle box will tilt, and then drive the pre-pressure water bag 9 to fall by gravity, so that the first magnet 15 and the second magnet 16 can be separated, and the pre-pressure water bag 9 can be separated from the inside of the storage box 6.

[0043] When water is injected into the pre-pressure water bag 9 through the water injection pipe 11, during the injection process, the water flow will push the blocking ball 17, and then the water flow can flow into the pre-pressure water bag 9. After the water flow enters the pre-pressure water bag 9, the blocking ball 17 will block the water injection through hole, effectively preventing the water inside the pre-pressure water bag 9 from flowing out of the pre-pressure water bag 9.

[0044] When the connecting block 12 slides inside the storage box 6, the elastic force of the spring will push the pushing block 19, and then the pushing block 19 will push the connecting block 12 to slide downward, effectively preventing the connecting block 12 from being stuck due to the influence of friction.

[0045] When the pushing block 19 pushes the connecting block 12, the anti-slip block 20 at the bottom of the connecting block 12 will be stuck inside the anti-slip groove 21 of the bottom connecting block 12, and then the friction between the two connecting blocks 12 can be increased, making the pre-pressure water bag 9 more stable when placed inside the storage box 6.

[0046] Before the transport vehicle body 1 starts, the fixing bolt 8 can be used to fix the fixing pin 25 inside the pin groove, and the fixing gasket is fixed on the side wall of the transport vehicle box. After that, when the transport vehicle box tilts and the pre-pressure water bag 9 filled with water inside the storage box 6 is poured out, the guide plate 22 can guide the pre-pressure water bag 9, so that the pre-pressure water bag 9 can fall better to the position where the pre-pressure water bag 9 needs to be arranged. At the same time, the guide groove 23 can make the contact area between the pre-pressure water bag 9 and the guide plate 22 larger, effectively preventing the pre-pressure water bag 9 from skewing during the falling process and making the landing point of the pre-pressure water bag 9 more accurate.

[0047] When the opening and closing door 10 slides inside the storage box 6, through the rolling of the anti-wear wheel 26, the sliding friction between the opening and closing door 10 and the storage box 6 can be changed into rolling friction, so that the friction between the opening and closing door 10 and the storage box 6 is smaller, and the wear between the storage box 6 and the opening and closing door 10 is less.

[0048] When the fixing knob fixes the storage box cover 7, by providing a rubber pad 27 on the side wall of the storage box cover 7, the contact area between the storage box cover 7 and the fixing knob can be made larger, so that the frictional force between the storage box cover 7 and the fixing knob can be made larger, and the fixing effect of the fixing knob on the storage box cover 7 can be better.

[0049] When the opening and closing door 10 slides inside the storage box body 6, through the restriction of the positioning rod 28 on the storage box body 6, the situation of the opening and closing door 10 tilting less during the sliding process can be made, and the sliding of the opening and closing door 10 can be more stable.

[0050] When the fixing bolt 8 is used for fixing, during the process of screwing the fixing bolt 8 into the threaded hole, the contact block 31 will first contact the bottom of the threaded hole, and then continue to screw in the fixing bolt 8. By the extrusion of the spring on the sliding plate 29, the frictional force between the fixing bolt 8 and the threaded hole can be made larger, so that the fixing effect of the fixing bolt 8 can be better.
