Description

Technical Field

[0001] This utility model belongs to the field of concrete beam curing technology, specifically relating to a precast concrete beam curing device. Background Technology

[0002] Concrete T-beams are frequently used in highway construction. Existing concrete T-beams are generally constructed using a prefabrication and installation method. After the concrete T-beams are prefabricated, they need to be water-cured to prevent cracking on the beam surface and to prevent cracks caused by temperature stress due to temperature differences between the inside and outside. Therefore, T-beam spray curing is an important step in ensuring the quality of the beam.

[0003] Utility model application CN202221366139.4 discloses a precast T-beam concrete curing device, including a nozzle, connecting rod, U-shaped water pipe, L-shaped fixing plate, reinforcing crossbar, water pump, and inlet pipe. The water pump delivers water from a tank through the inlet pipe, the pump, and the L-shaped fixing plate to the U-shaped water pipe, which then delivers the water to the nozzle. The nozzle sprays water onto the surface of the T-beam concrete. Simultaneously, a motor is activated by a switch, causing the first pulley to rotate. The first pulley, via a belt, drives a second pulley to rotate, which in turn drives a rotating shaft. This shaft then drives a first and a second traveling wheel, causing them to roll along a second track and a first track, respectively, thus moving the device. This allows the U-shaped water pipe to move while simultaneously spraying water onto the T-beam concrete, eliminating the need for manual watering.

[0004] However, the curing device in the above patent requires the pre-laying of tracks before it can be used, which makes its operation complicated and time-consuming. To address this problem, a precast concrete beam curing device is provided. Utility Model Content

[0012] Preferably, the outer circumference of the turntable is provided with a plurality of anti-slip bars.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting the sliding component, the fixed rod can slide towards the middle of the inner cavity of the frame at the same time, so that the pulley and both sides of the T-beam can be in close contact. During the movement of the device, the device can always slide along the extension direction of the T-beam, which solves the problem that the maintenance device needs to be laid in advance before it can be used, which makes the operation complicated and time-consuming.

[0015] 2. By adjusting the settings of the components, the height of the pulley can be adjusted, which allows for convenient adaptive adjustment of the pulley height according to T-beams of different heights. This enables the pulley to be mounted on both sides of T-beams of different heights, improving the flexibility of the device during use.

[0016] 3. The hub motor drives the wheels to rotate, which in turn drives the device to move, allowing the nozzle to slide along the T-beam.

[0023] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-5This embodiment provides the following technical solution: a precast concrete beam curing device, including a base 1, with a water tank 2 at the top of the base 1. The water tank 2 stores clean water, which is then pumped to nozzles 5 and sprayed onto the T-beam for curing. A first motor 3 is located on one side of the bottom of the base 1, with its output extending to the top of the base 1 and fixedly connected to a frame 4. Nozzles 5 are fixedly connected to the inner cavity of the frame 4. A mounting frame 17 is located at the top of the frame 4, with a sliding assembly inside the mounting frame 17. This sliding assembly allows a fixed rod 6 to slide simultaneously towards the center of the inner cavity of the frame 4, thereby ensuring close contact between the pulley 7 and both sides of the T-beam. During the movement of the device, the device can be kept in constant motion. Finally, the device slides along the extension direction of the T-beam, solving the problem that the maintenance device requires pre-laying tracks before use, which leads to complicated and time-consuming operation. The bottom of the sliding component is equipped with multiple fixed rods 6, each with an adjustment component. By adjusting the components, the height of the pulley 7 can be adjusted, allowing for easy adaptation to T-beams of different heights. This enables the pulley 7 to be mounted on both sides of T-beams of different heights, improving the flexibility of the device during use. Each adjustment component is equipped with a pulley 7, and drive components are located at the four corners of the bottom of the base 1. These drive components drive the device to move, allowing the nozzle 5 to slide along the T-beam.

[0025] In this embodiment, the drive assembly includes a fixed plate 8, a hub motor 9, and a wheel 10. The fixed plate 8 is rotatably connected to one corner of the bottom of the base 1 via a bearing. The hub motor 9 is located on one side of the outer wall of the fixed plate 8. The wheel 10 is fixedly sleeved on the output end of the hub motor 9. The hub motor 9 drives the wheel 10 to rotate, thereby driving the device to move and causing the nozzle 5 to slide along the T-beam.

[0026] In this embodiment, a liquid filling hopper is provided at the top of the water tank 2, which can be used to easily add clean water into the inner cavity of the water tank 2. A drain pipe is provided on one side of the outer wall of the water tank 2, which can drain the remaining clean water in the water tank 2. A ball valve is provided in the inner cavity of the drain pipe, which can control the drain pipe.

[0027] In this embodiment, the sliding assembly includes a lead screw 18, a knob 19, a guide rod 20, and two moving rods 21. One end of the lead screw 18 is rotatably connected to the rear side of the inner cavity of the mounting bracket 17 via a bearing, and the other end of the lead screw 18 extends to the front end of the mounting bracket 17. The guide rod 20 is disposed in the inner cavity of the mounting bracket 17. Two moving rods 21 are respectively screwed to the front and rear sides of the outer wall of the lead screw 18 and slidably sleeved on the front and rear sides of the outer wall of the guide rod 20. The bottom left and right sides of the two moving rods 21 are respectively fixedly connected to multiple fixed rods 6. Rotating the knob 19 causes the knob 19 to drive the lead screw 18. The rotation of the screw 18 causes the threads on the front and rear sides of the outer wall to generate relative thread rotation force, causing the two moving rods 21 to slide simultaneously toward the middle of the screw 18 under the limiting action of the guide rod 20, and the fixed rod 6 to slide simultaneously toward the middle of the inner cavity of the frame 4, thereby making the pulley 7 in close contact with both sides of the T-beam. During the movement of the device, it can always slide along the extension direction of the T-beam, which solves the problem that the maintenance device needs to be laid in advance before use, which makes the operation complicated and time-consuming.

[0028] In this embodiment, the threads on the front and rear sides of the outer wall of the lead screw 18 are arranged opposite to each other, so that when the lead screw 18 rotates, the front and rear sides of its outer wall generate relative thread rotational forces.

[0029] In this embodiment, the adjustment assembly includes a bracket 11, a screw 12, a turntable 13, a sliding plate 14, a slide rail 15, and a movable plate 16. The bracket 11 is disposed on one side of the outer wall of the fixed rod 6. One end of the screw 12 is rotatably connected to the top of the inner cavity of the bracket 11 via a bearing, and the other end of the screw 12 extends to the bottom end of the bracket 11 and is fixedly connected to the turntable 13. The sliding plate 14 is screwed onto the outer wall of the screw 12. The slide rail 15 is formed on the fixed rod 6, and the movable plate 16 is slidably embedded in the inner cavity of the slide rail 15. One end of the movable plate 16 is fixedly connected to the sliding plate 14. The other end of the movable plate 16 extends to the other side of the fixed rod 6 and is fixedly connected to the pulley 7. Rotating the turntable 13 causes the turntable 13 to drive the screw 12 to rotate. Under the action of the rotational force of the screw 12's outer wall thread, when the screw 12 rotates, the slide plate 14 can drive the movable plate 16 and the pulley 7 to slide up and down along the slide rail 15. The height of the pulley 7 can be adjusted, and the height of the pulley 7 can be easily adjusted according to the T-beams of different heights. This allows the pulley 7 to be mounted on both sides of T-beams of different heights, improving the flexibility of the device during use.

[0030] In this embodiment, a number of anti-slip bars are provided on the outer circumference of the turntable 13. When the turntable 13 is rotated, the anti-slip bars can press against the fingers to prevent the fingers from slipping out during the rotation of the turntable 13.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
