Description

Technical Field

[0001] The invention belongs to the technical field related to prefabrication of anti-collision guardrails, and more specifically, particularly relates to a construction device for pouring concrete anti-collision guardrails by an inverted method. Background Art

[0002] Prefabricated anti-collision guardrails are cast and formed by molds. Existing molds are usually formed in one piece. However, the concrete anti-collision guardrail is narrow at the top and wide at the bottom. In order to facilitate the removal of the prefabricated anti-collision guardrail from the mold, the inverted concrete casting method is used to prefabricate the anti-collision guardrail. The mold can be reused, which is in line with green and energy-saving construction. However, the prefabrication of anti-collision guardrails in the prior art has the following defects: In the prior art, when constructing anti-collision guardrails, since the construction device for pouring concrete anti-collision guardrails lacks a vibrating assembly, workers are required to stand on the top of the guardrail and use a concrete vibrator to vibrate the concrete to make the internal texture of the concrete uniform and eliminate internal bubbles, which undoubtedly increases the risk of falling. In previous accident lessons, there have been many high-altitude falling accidents. Safety belts are hung somewhere, which makes it inconvenient to move and easily causes the risk of falling.

[0003] In the prior art, the concrete vibrator used in the construction device for pouring concrete anti-collision guardrails mainly includes a vibrating rod, an eccentric mechanism is arranged inside the vibrating rod, and the eccentric mechanism is driven by a driving flexible shaft outside the vibrating rod; the current eccentric mechanism is widely used as a planetary mechanism, which includes a conical cavity, and the free end of the rotating rod driven by the flexible shaft is connected to an eccentric rotating body that can rotate on the conical inner surface of the conical cavity, so that when the eccentric rotating body rotates rapidly in the conical cavity, a higher vibration frequency can be generated. Considering that it is difficult for ordinary power drive mechanisms to change the speed for a long time, this is easy to damage the drive 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 anti-collision guardrail, which is prone to insufficient concrete vibration and the presence of bubbles, affecting the quality of the prefabricated anti-collision guardrail.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a construction device for pouring concrete anti-collision guardrail by inverted method is provided, in order to achieve a more practical and valuable purpose. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: The invention discloses a construction device for pouring concrete anti-collision guardrail by an inverted method. Through the arrangement of a movable block, a shell, and an annular telescopic part, the frame, the movable block, the shell, and the annular telescopic part move upward, and slide with the lower outer inclined surface of the mold through one side of the movable block, so that the movable block and the shell move horizontally close to the frame, and the annular telescopic part contracts to reduce the distance between the shell and the frame, thereby changing the position of the eccentric wheel in the two semi-conical plates, so as to change the vibration frequency of the shell and the movable block, and obtain a continuously changing vibration output frequency. Through the arrangement of the slide rod, the guide block, the push rod and the guide plate, the first movable plate moves upward to drive the two slide rods upward, and one end of the two slide rods respectively slides in contact with the inclined surfaces of one side of the two guide blocks, thereby making the two slide rods slide horizontally; the horizontal sliding of the two slide rods drives the two guide plates to move, and the ends of the two push rods that are away from each other slide in contact with the inclined surfaces of one side of the two guide plates, thereby making the two push rods approach each other; the two push rods approach each other to drive the two semi-cylinders and the two semi-conical plates approach each other, thereby reducing the distance between the two semi-conical plates, so as to shorten the path of the eccentric wheel rolling and change the vibration output frequency of the shell and the movable block to the mold. Finally, through the arrangement of the water bag, the slide plate, the push rod and the hydraulic chamber, the two semi-cylinders are brought close to each other to squeeze the two water bags respectively, so that the solutions in the two water bags enter the two hydraulic chambers respectively through the two connecting channels, and the solutions in the two hydraulic chambers push the two slide plates close to each other, and the two slide plates close to each other drive the two pairs of push rods close to each other; the two pairs of push rods close to each other drive the two semi-conical plates close to each other, further reducing the distance between the two semi-conical plates, further shortening the path of the eccentric wheel rolling, and finally obtaining a continuously changing vibration output frequency; so as to output richer vibration waves, it is beneficial to improve the vibration effect.

[0017] The invention discloses a construction device for pouring anti-collision guardrail by inverted concrete. When the device moves to the outer side of the lower part of the mold through the first movable plate, the eccentric wheel is located at the position where the diameter of the two semi-conical plates is larger. The swing rod rotates one circle, and the path that the eccentric wheel rolls is longer, so the eccentric wheel has a higher self-rotation speed. The higher self-rotation speed of the eccentric wheel will generate a greater centrifugal force, thereby increasing the vibration frequency and amplitude of the shell and the movable block, thereby vibrating the concrete in the lower layer of the mold at a high frequency. The higher vibration frequency and amplitude can more effectively reduce the internal friction and adhesion between the particles inside the concrete sharply, making the concrete in a heavy liquid state, and the aggregates slide and rearrange each other. The gaps between the aggregates are filled with mortar, and the bubbles are squeezed out, thereby achieving a better tamping effect. When the device moves to the outer side of the middle part of the mold through the first movable plate, the eccentric wheel is located at the position where the diameter of the inner side of the two semi-conical plates is smaller. The swing rod rotates one circle, and the path that the eccentric wheel rolls is shorter, so the eccentric wheel has a lower self-rotation speed. The centrifugal force generated by the eccentric wheel is smaller, so the vibration frequency and amplitude of the shell and the movable block are lower. Thereby, the vibration assembly moves up and down in the shell, so that the vibration frequency can be adjusted according to the height of the concrete pouring of the anti-collision guardrail, and finally a continuously changing vibration output frequency is obtained; so as to output richer vibration waves, which is conducive to improving the vibration effect.

[0035] Preferably, see Attachment Figure 1To Attachment Figure 2 A plurality of support plates 13 are fixedly connected between the inner side of each semi-ring plate 12 and one side of the housing 10 .

[0036] Specific use of the present invention: The staff applied a release agent on the inner wall of the mold 11, and placed the tied steel cage upside down into the mold 11. The method of three-layer oblique pouring was adopted. The first layer was controlled to be about 25 cm close to the lower end of the mold 11, and the second layer was poured to about 35 cm from the upper end of the mold 11, and then poured to the upper end of the mold 11.

[0037] When pouring the first layer, the worker pours concrete from both ends of the shell 10 into the mold 11, and vibrates and compacts the concrete while pouring the concrete. The worker stands on the upper end of the operating table 44 to operate, and extends the vibrating rod through the guide tube 48 downward into the mold 11, and the concrete in the mold 11 is vibrated and compacted inside and outside by the vibrating rod and the vibrating assembly in the shell 10, which is conducive to improving the efficiency of vibrating and compacting the concrete.

[0038] Next, the vibrating assembly in the housing 10 is started, and the stepping motor 43 is started to drive the limit frame 21 to rotate. The limit frame 21 rotates to drive the ball 22, the swing rod 23, and the eccentric wheel 24 to rotate around the limit frame 21, so that the eccentric wheel 24 performs planetary motion around the axis of the conical inner wall of the two semi-conical plates 26, that is, revolution; and rotates around the axis of the swing rod 23, that is, rotation, so as to form high-frequency vibration on the semi-cylinder 25 and the housing 19. The high-frequency vibration of the housing 19 is transmitted to the mold 11 through the movable block 18, so as to facilitate the vibration and compaction of the concrete in the mold 11.

[0039] When pouring the second layer, the worker should insert the vibrating rod quickly and pull it out slowly to allow the bubbles to fully overflow. The vibrating rod should be inserted 5cm into the vibrated lower layer of concrete to eliminate the stratified joints.

[0040] Next, the control system controls the two pairs of multi-stage telescopic rods 16 to extend and drive the two pairs of second movable plates 15 to move upward, and the two pairs of second movable plates 15 move upward and drive the two first movable plates 14 upward. The first movable plate 14 moves upward and drives the two slide bars 29 and the two fixed plates 31 to move upward, and the two fixed plates 31 move upward and drive the movable block 18 and the shell 19 to move upward, and the first movable plate 14 moves upward and drives the frame 17 to move upward, so that the frame 17, the movable block 18, the shell 19, and the annular telescopic member 20 move up and down synchronously. The frame 17, the movable block 18, the shell 19, and the annular telescopic member 20 move upward, and slide through one side of the movable block 18 and the lower outer inclined surface of the mold 11, so that the movable block 18 and the shell 19 move horizontally close to the frame 17, and the annular telescopic member 20 shrinks, reducing the distance between the shell 19 and the frame 17, thereby changing the position of the eccentric wheel 24 in the two semi-conical 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 a position with a smaller diameter inside the two semi-conical plates 26, the swing rod 23 rotates one circle, and the eccentric wheel 24 rolls over a shorter path, so the rotation speed of the eccentric wheel 24 is lower; and when the eccentric wheel 24 is located at a position with a larger diameter inside the two semi-conical plates 26, the swing rod 23 rotates one circle, and the eccentric wheel 24 rolls over a longer path, so the rotation speed of the eccentric wheel 24 is higher. Thus, by adjusting the position of the eccentric wheel 24 inside the two semi-conical plates 26, the vibration output frequency of the housing 19 and the movable block 18 can be changed.

[0041] At the same time, the first movable plate 14 moves upward to drive the two slide bars 29 to move upward, and one end of the two slide bars 29 slides in contact with the inclined surface of one side of the two guide blocks 32, so that the two slide bars 29 slide horizontally. The two slide bars 29 slide horizontally to drive the two guide plates 30 to move, and the ends of the two push rods 28 that are away from each other slide in contact with the inclined surface of one side of the two guide plates 30, so that the two push rods 28 approach each other. The two push rods 28 approach each other to drive the two semi-cylinders 25 and the two semi-conical plates 26 to approach each other, thereby reducing the distance between the two semi-conical plates 26, so as to shorten the path of the eccentric wheel 24 rolling over, and change the vibration output frequency of the housing 19 and the movable block 18 to the mold 11. Among them, the movement of the two slide bars 29 drives the two first sliders 49 to move respectively, and the two first sliders 49 slide in the two first slide grooves 50 respectively to compress the two first springs 51 to generate elastic force, so that under the elastic force of the two first springs 51, one end of the two slide bars 29 is always in contact with one side of the two guide blocks 32. The two semi-cylinders 25 approach each other, driving the two second sliders 33 to approach each other, so that the two second sliders 33 slide in the two second slide grooves 34 respectively, thereby compressing the two second springs 35 to generate elastic force, which is conducive to resetting the two semi-cylinders 25 away from each other under the elastic force of the two second springs 35.

[0042] Then, the two semi-cylinders 25 approach each other to squeeze the two water bags 41 respectively, so that the solutions in the two water bags 41 enter the two hydraulic chambers 36 respectively through the two connecting channels 40, and the solutions in the two hydraulic chambers 36 push the two slide plates 37 to approach each other, and the two slide plates 37 approach each other to drive the two pairs of push rods 38 to approach each other; the two pairs of push rods 38 approach each other to drive the two semi-conical plates 26 to approach each other, further reducing the distance between the two semi-conical plates 26, further shortening the path of the eccentric wheel 24 rolling, and finally obtaining a continuously changing vibration output frequency; to output more abundant vibration waves, which is conducive to improving the vibration effect. Among them, the two slide plates 37 approach each other to compress the two third springs 39 to generate elastic force, which is conducive to resetting the two slide plates 37 away from each other under the elastic force of the two third springs 39, so as to adjust the distance between the two semi-conical plates 26 and adjust the path of the eccentric wheel 24 rolling in the two semi-conical plates 26 and the two elastic members 42.

[0043] When pouring the third layer, the worker should insert the vibrating rod quickly and pull it out slowly to allow the bubbles to fully overflow. The vibrating rod should be inserted 5cm into the vibrated lower layer of concrete to eliminate the stratified joints.

[0044] The control system controls the two pairs of multi-stage telescopic rods 16 to move up and down and back and forth, and the first movable plates 14 move up and down to drive the frames 17, the movable blocks 18, the shells 19, and the annular telescopic parts 20 to move up and down. 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 where the diameter of the two semi-conical plates 26 is larger, and the swing rod 23 rotates one circle. The path that the eccentric wheel 24 rolls over is longer, so the rotation speed of the eccentric wheel 24 is higher. The higher rotation speed of the eccentric wheel 24 will generate greater centrifugal force, thereby increasing the vibration frequency and amplitude of the shell 19 and the movable block 18, thereby vibrating the concrete in the lower layer of the mold 11 at a high frequency. The higher vibration frequency and amplitude can more effectively reduce the internal friction and adhesion between the particles inside the concrete, making the concrete in a heavy liquid state, and the aggregates slide and rearrange each other. The gaps between the aggregates are filled with mortar, and the bubbles are squeezed out, thereby achieving a better tamping effect.

[0045] When the first movable plate 14 moves to the outside of the middle 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 swing rod 23 rotates one circle, and the path that the eccentric wheel 24 rolls over is shorter, so the rotation speed of the eccentric wheel 24 is lower. The centrifugal force generated by the eccentric wheel 24 is smaller, so that the vibration frequency and amplitude of the shell 19 and the movable block 18 are lower. As a result, the vibration assembly moves up and down in the shell 10, so that the vibration frequency can be adjusted according to the height of the concrete pouring of the anti-collision guardrail, and finally a continuously changing vibration output frequency is obtained; so as to output more abundant vibration waves, which is conducive to improving the vibration effect.

[0046] Finally, after the concrete is completely solidified, the staff rotates the rotating shaft 45 to remove the guide tubes 48 from the top of the shell 10. Then, the staff operates the equipment to push the shell 10 to one side in the direction of the semi-ring plate 12, so that the shell 10 can be turned over smoothly under the support of the two semi-ring plates 12 and the support plates 13. Then the staff operates the crane to lift the shell 10 so that the anti-collision guardrail can be taken out of the mold 11.

[0047] The invention discloses a construction device for pouring concrete anti-collision guardrail by an inverted method. By arranging a movable block 18, a shell 19 and an annular telescopic member 20, a frame 17, a movable block 18, a shell 19 and an annular telescopic member 20 are moved upward, and one side of the movable block 18 slides on the lower outer inclined surface of a mold 11, so that the movable block 18 and the shell 19 move horizontally close to the frame 17. The annular telescopic member 20 contracts to reduce the distance between the shell 19 and the frame 17, thereby changing the position of the eccentric wheel 24 in the two semi-conical 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. Then, through the arrangement of the slide rod 29, the guide block 32, the push rod 28 and the guide plate 30, the first movable plate 14 moves upward to drive the two slide rods 29 to move upward, and one end of the two slide rods 29 slides in contact with the inclined surfaces of one side of the two guide blocks 32 respectively, so that the two slide rods 29 slide horizontally; the horizontal sliding of the two slide rods 29 drives the two guide plates 30 to move, and the ends of the two push rods 28 that are away from each other slide in contact with the inclined surfaces of one side of the two guide plates 30 respectively, so that the two push rods 28 approach each other; the two push rods 28 approach each other to drive the two semi-cylinders 25 and the two semi-conical plates 26 to approach each other, thereby reducing the distance between the two semi-conical plates 26, so as to shorten the path of the eccentric wheel 24 rolling over, and change the vibration output frequency of the shell 19 and the movable block 18 to the mold 11. Finally, through the arrangement of the water bag 41, the slide plate 37, the push rod 38 and the hydraulic chamber 36, the two semi-cylinders 25 approach each other to squeeze the two water bags 41 respectively, so that the solutions in the two water bags 41 enter the two hydraulic chambers 36 respectively through the two connecting channels 40, and the solutions in the two hydraulic chambers 36 push the two slide plates 37 to approach each other, and the two slide plates 37 approach each other to drive the two pairs of push rods 38 to approach each other; the two pairs of push rods 38 approach each other to drive the two semi-conical plates 26 to approach each other, further reducing the distance between the two semi-conical plates 26, further shortening the path of the eccentric wheel 24 rolling, and finally obtaining a continuously changing vibration output frequency; so as to output richer vibration waves, which is beneficial to improving the vibration effect.

[0048] The construction device of the inverted concrete casting anti-collision guardrail of the present invention, when the first movable plate 14 is moved 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, and the swing arm 23 rotates one circle. The eccentric wheel 24 rolls over a longer path, so the eccentric wheel 24 rotates at a higher speed; the higher rotation speed of the eccentric wheel 24 will generate a greater centrifugal force, thereby causing the vibration frequency and amplitude of the shell 19 and the movable block 18 to increase, thereby 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 sharply, making the concrete in a heavy liquid state, the aggregates slide against each other and rearrange, the gaps between the aggregates are filled with mortar, and the bubbles are squeezed out, thereby achieving a better compaction effect. When the first movable plate 14 is moved to the outside of the middle of the mold 11, the eccentric wheel 24 is located at the position with the smaller diameter inside the two semi-conical plates 26. The swing rod 23 rotates one circle, and the path that the eccentric wheel 24 rolls is shorter, so the rotation speed of the eccentric wheel 24 is lower. The centrifugal force generated by the eccentric wheel 24 is smaller, so the vibration frequency and amplitude of the shell 19 and the movable block 18 are lower. In this way, the vibration assembly moves up and down in the shell 10, so that the vibration frequency can be adjusted according to the height of the concrete pouring of the anti-collision guardrail, and finally a continuously changing vibration output frequency is obtained; so as to output more abundant vibration waves, which is conducive to improving the vibration effect.
