Description

Technical Field

[0001] The present application relates to the technical field of civil engineering formwork, and in particular to a small slipform trolley for cast-in-place trapezoidal open ditch concrete. Background Art

[0002] As an important part of the airport airfield, a scientific and complete airport drainage system is particularly important, especially in rainy or cold areas. It can drain away a large amount of accumulated water in the airfield in a timely manner, prevent the airport pavement and structures from being eroded and washed away by water, and ensure the safety of airport operations.

[0003] Airport runways primarily draw their water from vast expanses of earth. Trapezoidal open trenches, constructed with precast concrete blocks or mortared stone masonry, are widely adopted by designers and builders due to their long routes, high workload, low cost (typically accounting for 3-5% of the contract value), ease of construction, and low maintenance costs. However, for the construction side, traditional precast block paving or mortared stone masonry requires numerous tedious steps, including component prefabrication, component transportation, masonry construction, and jointing. This requires significant investment in manpower, material resources, and machinery, resulting in low production efficiency and a significant mismatch between production resources and production capacity. Furthermore, the masonry is manually laid in sections (typically with expansion joints every 10 meters), resulting in inconsistent joint depths and prone to quality issues such as cracking and peeling. This results in a poor overall linearity and aesthetic appearance. Summary of the Invention

[0004] In order to simplify the complicated process of traditional ditch construction and improve construction efficiency, the present application provides a small slipform trolley for cast-in-place trapezoidal open ditch concrete.

[0005] This application provides a small slipform trolley for casting trapezoidal open ditch concrete, which adopts the following technical solution:

[0006] A small slipform trolley for casting trapezoidal open ditch concrete, comprising

[0007] A driving end and a running end, wherein the driving end includes a first bottom mold, and two opposite sides of the first bottom mold are fixedly connected to first side molds, and the driving end is provided with a driving assembly for driving the driving end and the running end to move together;

[0008] The running end includes a second bottom mold connected to the end of the first bottom mold, and the second side molds are hinged on two opposite sides thereof. A plurality of retractable support rods are hinged between the second side molds.

[0009] A control member for controlling the thickness of concrete is provided on the outer wall of the second side form.

[0010] By adopting the above technical solution, the sliding form trolley is adjusted into the open ditch by a crane, the control part is installed on the outer wall of the second side form, the angle between the second side form and the first bottom form is adjusted to the same slope as the open ditch design, and the length of the support rod is adjusted at the same time, so that the second side form is in contact with the open ditch slope that has been cast, and the control part is in contact with the uncast open ditch slope. After the angle between the second side form and the first bottom form is determined, the length of the support rod is fixed so that the two ends of the support rod are respectively in contact with the two second side forms, thereby fixing the second side form, so that it can adapt to open ditches with different slopes.

[0011] A pouring space is formed between the second side form, the control part and the already poured open ditch slope, which facilitates the pouring of the open ditch slope. When the pouring of this section of the slope is completed, the sliding form trolley is controlled by the drive component to move and pour the next section of the slope, thereby simplifying the tedious process of traditional ditch construction and improving construction efficiency.

[0012] Preferably, the second bottom mold includes two third bottom molds that can move toward or away from each other, and the two ends of the two third bottom molds that are close to each other are provided with sliding grooves, and the same slide plate is slidably arranged in the two sliding grooves, and the third bottom mold is provided with a locking member for fixing the slide plate in the sliding groove.

[0013] By adopting the above technical solution, the distance between the two third bottom molds is adjusted according to the width of the bottom of the open ditch. After the adjustment is completed, the locking part is used to fix the slide plate, thereby fixing the two third bottom molds, thereby enhancing the applicability of the sliding mold trolley for open ditches of different widths.

[0014] Preferably, a plurality of threaded holes are provided on the third bottom mold, and the locking member is a bolt, which is threadedly connected to the side wall of the threaded hole and is used to tighten the slide plate.

[0015] By adopting the above technical solution, after the distance between the two third templates is adjusted, the bolt is rotated in the threaded hole until the end of the bolt presses the slide plate, thereby fixing the slide plate to the third template and reducing the possibility of changes in the width of the second template.

[0016] Preferably, a dovetail groove is provided at the end of the first bottom mold close to the second bottom mold, the length direction of the dovetail groove is perpendicular to the moving direction of the first bottom mold, and the end of the third bottom mold close to the first bottom mold is fixedly connected with a dovetail block for sliding in the dovetail groove.

[0017] By adopting the above technical solution, since the width of the first bottom mold is fixed, the dovetail block slides in the dovetail groove, thereby increasing the width of the second bottom mold, and the cooperation between the dovetail block and the dovetail groove enables the first bottom mold to drive the second bottom mold to move during the movement process.

[0018] Preferably, the driving assembly includes a drum fixedly connected between the first side molds and a driving source for driving the drum to rotate, a traction rope for pulling the slipform trolley is wound around the drum, and one end of the traction rope is fixed in the open ditch.

[0019] By adopting the above technical solution, one end of the traction rope is fixed in the open ditch, and the driving source drives the reel to rotate to reel in the traction rope, thereby pulling the sliding form trolley to move in the open ditch.

[0020] Preferably, a pulley is rotatably provided between the two first side molds, and the traction rope is wound around the pulley.

[0021] By adopting the above technical solution, the rotation of the traction rope on the pulley can reduce friction, and the pulley plays a limiting role on the traction rope, so that the traction rope can always be located in the same straight line with the fixed end of the traction rope during the winding process, reducing the deviation of the sliding trolley during the movement process, and at the same time it is more labor-saving to pull the sliding trolley.

[0022] Preferably, a plurality of vibrating members are provided on the inner wall of the second side mold.

[0023] By adopting the above technical solution, since the pouring space of the open ditch slope is small, uneven vibration occurs when the concrete of the open ditch slope is vibrated with an inserted vibrator. The vibrating piece on the inner wall of the second side form can vibrate the second side form, thereby vibrating the concrete on one side of the second side form, making the concrete pouring more uniform, full and dense, and reducing the occurrence of honeycombed surface.

[0024] Preferably, the control member is a square clamping block, and the clamping block is detachably connected to the outer wall of the end of the second side mold close to the first side mold.

[0025] By adopting the above technical solution, when the clamping block abuts against the uncast open ditch slope, the clamping block can serve as a template to control the pouring thickness of concrete. The clamping block is detachably connected to the second side form. When pouring open ditch slopes of different thicknesses, the adaptability of the device is enhanced by replacing clamping blocks of different sizes. The clamping block is installed on the outer wall of the end of the second side form close to the first side form, which can maximize the pouring length of each open ditch section and improve construction efficiency.

[0026] Preferably, the corner of the clamping block close to the first side mold is set as a chamfer.

[0027] By adopting the above technical solution, the corner of the clamping block close to the first side mold is set as a chamfer, which can reduce the resistance of the sliding mold trolley during operation and facilitate the movement of the sliding mold trolley in the open ditch.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Adjust the angle between the second side form and the first bottom form to the same slope as the open ditch design, and at the same time adjust the length of the support rod so that the second side form abuts the completed open ditch slope and the control member abuts the uncast open ditch slope. After the angle between the second side form and the first bottom form is set, fix the length of the support rod so that both ends of the support rod abut against the two second side forms respectively, thereby fixing the second side form to adapt to open ditches with different slopes;

[0030] A pouring space is formed between the second side form, the control component and the already poured open ditch slope, making it easier to pour the open ditch slope. Once the pouring of this section of slope is completed, the drive assembly controls the movement of the sliding formwork trolley to pour the next section of slope, thereby simplifying the tedious process of traditional ditch construction and improving construction efficiency.

[0031] 2. Adjust the distance between the two third bottom molds according to the width of the open ditch bottom. After the adjustment is completed, fix the slide plate with the locking piece to fix the two third bottom molds, thereby enhancing the applicability of the sliding mold trolley and being used for open ditches of different widths.

[0032] 3. Due to the limited pouring space on the open ditch slope, the concrete on the open ditch slope will be unevenly vibrated when vibrated with an insert vibrator. However, the vibrating element on the inner wall of the second side form can vibrate the second side form, thereby vibrating the concrete on one side of the second side form, making the concrete pouring more uniform, full, and dense, and reducing the occurrence of honeycombing.

[0033] 4. When the clamping block abuts against the open ditch slope to be poured, the clamping block can serve as a template to control the pouring thickness of concrete. The clamping block is detachably connected to the second side form. When pouring open ditch slopes of different thicknesses, the adaptability of the device can be enhanced by replacing clamping blocks of different sizes. The clamping block is installed on the outer wall of the end of the second side form close to the first side form, which can maximize the pouring length of each open ditch section and improve construction efficiency.

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] The embodiment of the present application discloses a small slipform trolley for casting trapezoidal open ditch concrete. Figure 1 and Figure 2 , including a driving end 1 and a running end 2, the driving end 1 includes a first bottom mold 11, the opposite ends of the first bottom mold are fixedly connected to the first side mold 12, and a driving component 13 is provided above the first bottom mold 11 to drive the driving end 1 and the running end 2 to move together. The driving assembly 13 includes a drum 131 and a driving source 132 for driving the drum 131 to rotate. A fixed rod 14 is fixedly connected between the two first side molds 12. The drum 131 is sleeved on the fixed rod 14 and can rotate. A first supporting plate 15 parallel to the fixed rod 14 is also fixedly connected between the two first side molds 12. The driving source 132 is a servo motor and is fixed on the first supporting plate 15. The rotating shaft of the driving source 132 and the drum of the drum 131 are wound with the same transmission belt 135. When the rotating shaft of the driving source 132 rotates, the drum 131 is driven to rotate through the transmission belt 135. A traction rope 133 for pulling the slipform trolley is wound around the drum 131. One end of the traction rope 133 is fixed to the outer wall of the drum 131, and the other end of the traction rope 133 is fixed in the open ditch.

[0041] Reference Figure 1 and Figure 2A pulley 16, located below a reel 131, is rotatably mounted between the two first side molds 12. A straight rod 17 is fixedly connected between the two first side molds 12. Two parallel lugs 18 are fixedly attached to the first bottom mold 11. The straight rod 17 passes through both lugs 18. The pulley 16 is rotatably connected to the straight rod 17 and located between the two lugs 18. A traction rope 133 is wound around the pulley 16. The end of the traction rope 133 passing through the pulley 16 is fixedly connected to an anchor hook 134. A fixing member (not shown) is placed in the open trench. In this embodiment, the fixing member is a temporary anchor pier. The anchor hook 134 is hooked to the fixing member. A second support plate 19 is fixedly connected between the two first side molds 12. The second support plate 19 is located above the drive source 132. A control console 3 for controlling the opening and closing of the drive source 132 is placed on the second support plate 19.

[0042] The control console 3 controls the rotation of the rotating shaft of the driving source 132, and the transmission belt 135 in turn drives the reel 131 to rotate. The reel 131 reels the traction rope 133 while rotating. One end of the traction rope 133 is fixed to the fixed part of the open ditch, thereby pulling the slipform trolley toward the fixed part. The two ear plates 18 limit the pulley 16, making it difficult for the pulley 16 to slide on the straight rod 17. The pulley 16 limits the traction rope 133. During the reeling process, the traction rope 133 is placed on the straight line between the pulley 16 and the fixed part, reducing the deviation of the slipform trolley during movement and reducing the force required to pull the slipform trolley.

[0043] Reference Figure 3 and Figure 4 The operating end 2 includes a second bottom mold 21, with second side molds 22 hingedly connected to opposite sides of the second bottom mold. The second bottom mold 21 includes two third bottom molds 211. The adjacent side walls of the two third bottom molds 211 are each provided with a slide groove 212. The same slide plate 213 is slidably disposed in the two slide grooves 212. The third bottom mold 211 is provided with a locking member 214 for securing the slide plate 213 in the slide groove 212. The third bottom mold 211 has a plurality of threaded holes. The locking member 214 is a bolt. One end of the bolt passes through the threaded hole and can be tightened against the slide plate 213, thereby securing the slide plate 213 in the slide groove 212. When the width of the second bottom mold 21 needs to be adjusted, the bolts are loosened and the two third bottom molds 211 are moved away from or closer to each other. After the two third bottom molds 211 are adjusted to a suitable distance, the bolts are tightened to fix the slide plate 213, thereby fixing the two third bottom molds 211, thereby enhancing the applicability of the sliding mold trolley and can be used for open ditches of different widths.

[0044] Reference Figure 2 and Figure 3The end of the first bottom mold 11 near the third bottom mold 211 is provided with a dovetail groove 111, the length direction of which is perpendicular to the movement direction of the first bottom mold 11. The end of the third bottom mold 211 near the first bottom mold 11 is fixedly connected with a dovetail block 215, which is slidably arranged in the dovetail groove 111. When the distance between the two third bottom molds 211 is adjusted, the dovetail block 215 slides in the dovetail groove 111, and when the driving end 1 moves, the dovetail block 215 and the dovetail groove 111 are engaged, so that the driving end 1 can drive the running end 2 to move in the open groove.

[0045] Reference Figure 3 A support rod 4 is hingedly connected between the two second side molds 22. The support rod 4 includes two connecting tubes 41 and a threaded rod 42 located between the two connecting tubes 41. The threaded rod 42 is provided with threaded segments with opposite rotation directions at both ends. The inner side walls of the two connecting tubes 41 are provided with threaded segments. One end of the threaded rod 42 is inserted into one of the connecting tubes 41 so that one threaded segment is threadedly connected to the inner wall of the connecting tube 41. The other end of the threaded rod 42 is inserted into the other connecting tube 41 so that the other threaded segment is threadedly connected to the inner wall of the connecting tube 41. The end of the connecting tube 41 away from the threaded rod 42 is hinged to the second side mold 22. A plurality of oppositely arranged insertion holes 221 are respectively formed on the two second side molds 22. The same pull rod 43 is passed through the two opposite insertion holes 221. Nuts are threadedly connected to both ends of the pull rod 43.

[0046] To rotate the second side form 22, the threaded rod 42 is screwed to adjust the length of the support rod 4, thereby adjusting the angle between the second side form 22 and the second bottom form 21. When the second side form 22 is adjusted to the desired angle, the tie rod 43 is inserted into the insertion hole 221 and the nut is tightened until it abuts against the outer wall of the second side form 22. The support rod 4 and tie rod 43 support the second side form 22, reducing the risk of displacement during concrete pouring.

[0047] Reference Figure 3 Several vibrators 5 are fixed to the inner wall of the second side form 22. These vibrators are attached and connected to the control console 3 via cables. When pouring concrete on both sides of the trench wall, the inserted vibrators can be inserted into the concrete on the trench wall. Simultaneously, the attached vibrators are activated through the control console 3 to vibrate the second side form 22. The vibrations of the second side form 22 are transmitted to the trench wall concrete, causing vibration. This ensures a more uniform, fuller, and denser concrete pour, reducing the occurrence of honeycombing.

[0048] Reference Figure 3A control member is detachably connected to the outer wall of the second side form 22. The control member is a square clamping block 6. The clamping block 6 is detachably connected to the outer wall of the end of the second side form 22 near the first side form 12. The corner of the clamping block 6 near the first side form 12 is set as a chamfer. When the clamping block 6 is against the uncast open ditch slope, the clamping block 6 can serve as a template to control the pouring thickness of concrete. The clamping block 6 is detachably connected to the second side form 22. When pouring open ditch slopes of different thicknesses, the adaptability of the device is enhanced by replacing clamping blocks 6 of different sizes. The clamping block 6 is installed on the outer wall of the end of the second side form 22 near the first side form 12, which can maximize the pouring length of each open ditch section and improve construction efficiency. The corner of the clamping block 6 near the first side form 12 is set as a chamfer, which can make the clamping block 6 fit better with the ditch wall, reduce the possibility of the clamping block 6 scratching the ditch wall, and make the sliding trolley move more smoothly and smoothly.

[0049] The implementation principle of a small slipform trolley for cast-in-place trapezoidal open ditch concrete in an embodiment of the present application is as follows: The bolts are loosened, and by restricting the mutual rotation of the third bottom form 211 and the second side form 22, the threaded screw 42 is rotated to move the two third bottom forms 211 away from each other. When the two third bottom forms 211 are adjusted to an appropriate distance, the bolts are tightened to fix the slide plate 213, thereby fixing the two third bottom forms 211. The threaded screw 42 is then rotated, and the second side form 22 is rotated, and the angle between the second side form 22 and the second bottom form 21 is adjusted so that a portion of the second side form 22 abuts the cast open ditch slope and the clamping block 6 abuts the uncast open ditch slope, thereby forming a casting space for the open ditch sidewall. The pull rod 43 is then inserted into the insertion hole 221, and the nut is tightened until the nut abuts the outer wall of the second side form 22, thereby fixing the second side form 22.

[0050] Pour concrete into the pouring space of the side wall of the open ditch, and insert the insert vibrator into the concrete. At the same time, the console 3 starts the attached vibrator and vibrates the concrete. After the concrete is vibrated evenly, full and densely, the anchor hook 134 is fixed to the temporary anchor pier in the open ditch. The console 3 controls the drive source 132 to start, thereby driving the reel 131 to rotate through the transmission belt 135. The reel 131 reels the traction rope 133 while rotating, thereby pulling the slipform trolley to move in the open ditch. When it moves to the next section of the uncast open ditch, the above operation process is repeated.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
