Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of prefabrication of crash barriers, and more particularly relates to a construction device for inverted-method concrete-pouring crash barriers. BACKGROUND

[0002] The prefabricated crash barriers are formed by pouring through a mold, and the existing mold is usually integrally formed. However, the concrete crash barrier is narrow at the top and wide at the bottom. In order to facilitate the removal of the prefabricated crash barrier from the mold, the inverted-method concrete-pouring method is used to prefabricate the crash barrier, and the mold can be reused, which meets the green and energy-saving construction. However, the prefabrication of the crash barrier in the prior art has the following defects:

[0003] In the prior art, when the crash barrier is constructed, the concrete-pouring crash barrier construction device lacks a vibrating assembly, so the worker needs to stand on the top of the barrier and use a concrete vibrator to vibrate the concrete, so as to make the internal texture of the concrete uniform and eliminate internal bubbles, which undoubtedly increases the risk of falling. In the usual accident lessons, there are many falling accidents at high places, the safety belt is hung somewhere, and it is not convenient to move, which is easy to cause falling danger.

[0004] In the prior art, the concrete vibrator used in the concrete-pouring crash barrier construction device mainly includes a vibrating rod, and an eccentric mechanism is arranged in the vibrating rod. The eccentric mechanism is driven by a driving flexible shaft outside the vibrating rod. At present, the eccentric mechanism widely adopts a planetary mechanism, which includes a conical cavity. The free end shaft of the rotating rod driven by the flexible shaft is connected with an eccentric rotating body that can rotate on the conical inner surface of the conical cavity. Thus, when the eccentric rotating body rotates rapidly in the conical cavity, a high vibration frequency can be generated. Considering that it is difficult for the ordinary power-driven mechanism to change the speed for a long time, which is easy to damage the driving mechanism. Therefore, the speed of the flexible shaft of the vibrator is basically stable, which makes the vibration frequency of the vibrator basically fixed, and the vibration frequency cannot be adjusted according to the height of the concrete pouring of the crash barrier, which is easy to cause the concrete to be not fully vibrated and bubbles to exist, affecting the quality of the prefabricated crash barrier.

[0005] Therefore, in view of the above-mentioned defects in the prior art, the present application provides a construction device for inverted-method concrete-pouring crash barriers, so as to achieve the purpose of being more practical and valuable. SUMMARY

[0050] Preferably, referring to the accompanying drawings Figure 9 Two second movable plates 15 are fixedly arranged at two ends of each first movable plate 14 respectively; and two pairs of multi-stage telescopic rods 16 are arranged on the inner bottom side of the shell 10, and the extending ends of each pair of multi-stage telescopic rods 16 are fixedly connected with the lower sides of the two second movable plates 15 respectively.

[0051] Preferably, referring to the accompanying drawings Figure 1 to the accompanying drawings Figure 2 A plurality of supporting plates 13 are fixedly and connected between the inner side of each half-ring plate 12 and one side of the shell 10.

[0052] The specific use method of the present application is as follows:

[0053] The staff members apply release agent on the inner wall of the mold 11, and then place the inverted reinforced cage into the mold 11; and the method of pouring concrete in three layers in different parts is adopted; the first layer is controlled to be about 25 cm close to the lower end of the mold 11, the second layer is poured to be about 35 cm away from the upper end of the mold 11, and then the upper end of the mold 11 is poured.

[0054] When the first layer is poured, the staff members pour concrete into the mold 11 from the two ends of the shell 10, and vibrate and tamp the concrete while pouring; the staff members operate on the upper end of the operating table 44, and the vibrating rod is inserted into the mold 11 through the guide pipes 48, so that the inner and outer double vibration and tamping of the concrete in the mold 11 are realized through the vibrating rod and the vibration and tamping assembly in the shell 10, which is beneficial to improving the efficiency of the vibration and tamping of the concrete.

[0055] Then, the vibration and tamping assembly in the shell 10 is started, the stepping motor 43 is started to drive the limiting frame 21 to rotate, the limiting frame 21 drives the spherical body 22, the swing rod 23 and the eccentric wheel 24 to rotate around the limiting frame 21, so that the eccentric wheel 24 rotates around the axis of the conical inner wall of the two half-conical plates 26, i.e. revolution, and rotates around the axis of the swing rod 23, i.e. rotation, so as to form high-frequency vibration of the half-cylinder 25 and the shell 19. The high-frequency vibration of the shell 19 is transmitted to the mold 11 through the movable block 18, so as to vibrate and tamp the concrete in the mold 11.

[0056] When the second layer is poured, the staff members operate the vibrating rod to be inserted and pulled out quickly and slowly, so that the bubbles are fully overflowed, and the vibrating rod is inserted into the lower layer of concrete by 5 cm, so as to eliminate the layered joint.

[0057] Then, the control system controls the two pairs of multi-stage telescopic rods 16 to extend, driving the two pairs of second movable plates 15 to move upwards, and the two pairs of second movable plates 15 moving upwards drives the two first movable plates 14 to move upwards. The first movable plate 14 moving upwards drives the two sliding rods 29 and the two fixed plates 31 to move upwards, and the two fixed plates 31 moving upwards drives the movable block 18 and the shell 19 to move upwards, and the first movable plate 14 moving upwards drives the frame 17 to move upwards, so that the frame 17, the movable block 18, the shell 19 and the annular telescopic part 20 move up and down synchronously. The frame 17, the movable block 18, the shell 19 and the annular telescopic part 20 move upwards, and slide on the lower outer side slope of the mold 11 through one side of the movable block 18, so that the movable block 18 and the shell 19 move horizontally close to the frame 17, the annular telescopic part 20 contracts, and the distance between the shell 19 and the frame 17 is reduced, so as to change the position of the eccentric wheel 24 in the two half-cone plates 26, so as to change the vibration frequency of the shell 19 and the movable block 18, and obtain a continuously changing vibration output frequency. When the eccentric wheel 24 is located at the position with smaller diameter inside the two half-cone plates 26, the swing lever 23 rotates one circle, the path of the eccentric wheel 24 is shorter, and the self-rotation speed of the eccentric wheel 24 is lower; when the eccentric wheel 24 is located at the position with larger diameter inside the two half-cone plates 26, the swing lever 23 rotates one circle, the path of the eccentric wheel 24 is longer, and the self-rotation speed of the eccentric wheel 24 is higher. Thus, the vibration output frequency of the shell 19 and the movable block 18 can be changed by adjusting the position of the eccentric wheel 24 in the two half-cone plates 26.

[0058] Meanwhile, the first movable plate 14 moving upwards drives the two sliding rods 29 to move upwards, and the two sliding rods 29 slide on the one side slope of the two guide blocks 32 through one end of the two sliding rods 29, so that the two sliding rods 29 slide horizontally. The two sliding rods 29 sliding horizontally drives the two guide plates 30 to move, and the two top rods 28 slide on the one side slope of the two guide plates 30 through the ends of the two top rods 28 away from each other, so that the two top rods 28 move close to each other. The two top rods 28 moving close to each other drives the two half-cylinders 25 and the two half-cone plates 26 to move close to each other, so as to reduce the distance between the two half-cone plates 26, so as to shorten the path of the eccentric wheel 24 and change the vibration output frequency of the shell 19 and the movable block 18 to the mold 11. Among them, the two sliding rods 29 moving respectively drives the two first sliding blocks 49 to move, and the two first sliding blocks 49 sliding in the two first sliding grooves 50 respectively compresses the two first springs 51 to generate elastic force, so as to make one end of the two sliding rods 29 slide on the one side of the two guide blocks 32 under the elastic force of the two first springs 51. The two second sliding blocks 33 move close to each other through the two half-cylinders 25 moving close to each other, so that the two second sliding blocks 33 slide in the two second sliding grooves 34 respectively, so as to compress the two second springs 35 to generate elastic force, which is conducive to the two half-cylinders 25 moving away from each other under the elastic force of the two second springs 35.

[0059] Then, the two semi-cylinders 25 approach each other and squeeze the two water bladders 41, causing the solution inside the two water bladders 41 to enter the two hydraulic chambers 36 through the two connecting channels 40. The solution in the two hydraulic chambers 36 pushes the two sliding plates 37 closer together, which in turn drives the two pairs of push rods 38 closer together. The two pairs of push rods 38 then drive the two semi-conical plates 26 closer together, further reducing the distance between the two semi-conical plates 26 and further shortening the path of the eccentric wheel 24, ultimately resulting in a continuously varying vibration output frequency. This outputs richer vibration waves, which is beneficial for improving the vibration effect. The approaching of the two sliding plates 37 compresses the two third springs 39, generating elastic force. This elastic force helps the two sliding plates 37 to move away from each other and reset under the action of the two third springs 39, thereby allowing adjustment of the distance between the two semi-conical plates 26 and the path of the eccentric wheel 24 within the two semi-conical plates 26 and the two elastic elements 42.

[0060] When pouring the third layer, the workers should insert the vibrator quickly and withdraw it slowly to allow air bubbles to escape fully. The vibrator should be inserted 5cm into the concrete of the lower layer that has already been vibrated to eliminate the layer joints.

[0061] The control system manipulates two pairs of multi-stage telescopic rods 16 to extend and retract, causing two first movable plates 14 to move up and down. The up and down movement of the first movable plates 14 causes several frames 17, movable blocks 18, shells 19, and annular telescopic components 20 to move up and down. When the first movable plates 14 move to the lower outer part of the mold 11, the eccentric wheel 24 is located at the position with the larger diameter of the two semi-conical plates 26. When the swing rod 23 rotates one revolution, the eccentric wheel 24 rolls a longer path, resulting in a higher rotational speed. The higher rotational speed of the eccentric wheel 24 generates a greater centrifugal force, which leads to an increase in the vibration frequency and amplitude of the shell 19 and movable blocks 18. This results in high-frequency vibration of the concrete in the lower layer of the mold 11. The higher vibration frequency and amplitude can more effectively reduce the internal friction and adhesion between the concrete particles, making the concrete a heavy liquid state. The aggregates slide and rearrange themselves, the gaps between the aggregates are filled with mortar, and air bubbles are squeezed out, thus achieving a better compaction effect.

[0062] When the first movable plate 14 moves to the outer middle part of the mold 11, and the eccentric wheel 24 is located at the position with the smaller diameter inside the two semi-conical plates 26, the eccentric wheel 24 rolls a shorter path when the rocker arm 23 rotates one revolution, resulting in a lower rotational speed. The centrifugal force generated by the eccentric wheel 24 is smaller, thus lowering the vibration frequency and amplitude of the housing 19 and the movable block 18. This allows the vibrating assembly to move up and down within the housing 10, enabling adjustments to the vibration frequency based on the height of the concrete pouring for the crash barrier, ultimately achieving a continuously varying vibration output frequency; this outputs richer vibration waves, which is beneficial for improving the vibration effect.

[0063] Finally, after the concrete has completely solidified, the workers rotate the shaft 45 to remove several guide tubes 48 from above the outer casing 10. Then, the workers operate the equipment to push the outer casing 10 towards one side of the semi-ring plates 12, so that the outer casing 10 can be smoothly flipped over under the support of the two semi-ring plates 12 and several support plates 13. Next, the workers operate the crane to lift the outer casing 10 so that the crash barrier can be removed from the mold 11.

[0064] The present invention discloses a construction device for pouring concrete for crash barriers using an inverted method. Through the arrangement of a movable block 18, a housing 19, and an annular telescopic component 20, the frame 17, movable block 18, housing 19, and annular telescopic component 20 move upwards. The movable block 18 slides along the lower outer slope of the mold 11 on one side, causing the movable block 18 and housing 19 to move horizontally closer to the frame 17. The annular telescopic component 20 contracts, reducing the distance between the housing 19 and the frame 17, thereby changing the position of the eccentric wheel 24 within the two semi-conical plates 26. This allows for changes in the vibration frequency of the housing 19 and movable block 18, resulting in a continuously varying vibration output frequency. Then, through the arrangement of slide rod 29, guide block 32, push rod 28, and guide plate 30, the first movable plate 14 moves upward, driving the two slide rods 29 to move upward. One end of each slide rod 29 slides in contact with one side of the inclined surface of each guide block 32, thereby causing the two slide rods 29 to slide horizontally. The horizontal sliding of the two slide rods 29 drives the two guide plates 30 to move. The ends of the two push rods 28 that are far apart slide in contact with one side of the inclined surface of each guide plate 30, thereby causing the two push rods 28 to move closer to each other. The two push rods 28 moving closer to each other drive the two semi-cylinders 25 and the two semi-conical plates 26 to move closer to each other, thereby reducing the distance between the two semi-conical plates 26, so as to shorten the path of the eccentric wheel 24 and change the vibration output frequency of the housing 19 and the movable block 18 on the mold 11. Finally, through the arrangement of water bladder 41, sliding plate 37, push rod 38, and hydraulic chamber 36, the two semi-cylinders 25 approach each other and squeeze the two water bladders 41, thereby causing the solution in the two water bladders 41 to enter the two hydraulic chambers 36 through the two connecting channels 40. The solution in the two hydraulic chambers 36 pushes the two sliding plates 37 closer together, which in turn drives the two pairs of push rods 38 closer together. The two pairs of push rods 38 then drive the two semi-conical plates 26 closer together, further reducing the distance between the two semi-conical plates 26 and further shortening the path of the eccentric wheel 24, ultimately resulting in a continuously varying vibration output frequency. This outputs richer vibration waves, which is beneficial for improving the vibration effect.

[0065] The construction device for pouring concrete for crash barriers according to the present invention, when the first movable plate 14 moves to the lower outer side of the mold 11, the eccentric wheel 24 is located at the position with the larger diameter of the two semi-conical plates 26. When the swing rod 23 rotates once, the eccentric wheel 24 rolls a longer path, so the rotation speed of the eccentric wheel 24 is higher. The higher rotation speed of the eccentric wheel 24 will generate a greater centrifugal force, thereby increasing the vibration frequency and amplitude of the shell 19 and the movable block 18, thus performing high-frequency vibration on the concrete in the lower layer of the mold 11. The higher vibration frequency and amplitude can more effectively reduce the internal friction and adhesion between the particles inside the concrete, making the concrete a heavy liquid state, the aggregate slides and rearranges itself, the gaps between the aggregates are filled by mortar, and the air bubbles are squeezed out, thereby achieving a better compaction effect. When the eccentric wheel 24 moves to the outer center of the mold 11 via the first movable plate 14, and is positioned at the smaller diameter inner diameter of the two semi-conical plates 26, the swing arm 23 rotates one revolution. The eccentric wheel 24 travels a shorter path, resulting in a lower rotational speed. The centrifugal force generated by the eccentric wheel 24 is smaller, thus lowering the vibration frequency and amplitude of the housing 19 and the movable block 18. This allows the vibrating assembly to move up and down within the housing 10, enabling adjustments to the vibration frequency based on the height of the concrete pouring for the crash barrier, ultimately achieving a continuously varying vibration output frequency. This results in a richer output of vibration waves, improving the vibration effect.
