Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic machinery, and particularly relates to a canal forming machine. Background Art

[0002] The forms of the roadbed drainage canals in railway yards are diverse, and common shapes include trapezoidal canals, rectangular canals, etc. The traditional construction process requires nine major steps, such as leveling and excavation, channel finishing, pouring the bottom slab, processing the mold, supporting the mold, grouting, plastering the canal wall, building the retaining wall, and finally curing. The construction procedures are numerous, and the on-site progress is slow. Currently, a canal forming machine (or canal slip form machine) is usually used to replace manual operation. Only by continuously adding concrete into the canal forming machine and through repeated mechanical vibration, a standard canal can be made, which greatly reduces the construction steps and labor costs and speeds up the construction speed of the canal. However, the surface of the canal formed by the canal forming machine is usually uneven and not smooth, and subsequent finishing by staff is required. Moreover, after the canal is built, staff also need to manually set expansion joints at intervals to prevent the drainage canal from being damaged due to thermal expansion and contraction of the environment.

[0003] In the face of the above problems, the existing solutions usually involve workers repairing and finishing the surface of the formed canal. For example, in a canal forming machine for water conservancy projects (patent publication number: CN219033105U), the staff stand on the working plate and then trim the sides of the canal. This kind of canal surface repair requires the staff to squat on the working plate for a long time to operate, which not only increases the burden on the staff but also raises the construction cost. To solve the problem of expansion joints, a Chinese patent discloses a farmland canal expansion joint cutting device (patent publication number: CN212835295U). The staff need to push the fixed frame to move the device forward to the directly above of the canal, and then start the first motor to drive the seam pressing plate to move downward. The seam pressing plate cuts and squeezes the canal surface to form expansion joints. Since the canal is extruded and formed by the canal forming machine, the inside of the canal is already dense and firm. When the seam pressing plate squeezes the canal surface again, it cannot penetrate into the concrete, and the produced expansion joints are not ideal, with insufficient depth. Moreover, the staff also need to repeatedly move the device to adjust the position of making the expansion joints, which is time-consuming and laborious and increases the construction cost.

[0004] In summary, during the existing canal production process, after the canal is formed, not only does it require the staff to manually level and finish it, but also a mobile expansion joint cutting device is needed to make expansion joints. The whole construction process is time-consuming and laborious, increasing the construction cost. Summary of the Invention

Specific embodiments

[0030] As Figures 1 - 10 shown,

[0031] A canal molding machine includes a molding machine body 1 and a molding die 2 provided on one side of the molding machine body 1; an integral smoothing and cutting assembly 3 is provided on the outer surface of the molding die 2; the integral smoothing and cutting assembly 3 at least includes a conveyor belt 301, a plurality of rolling rollers 302, a plurality of smoothing housings 303 and a plurality of guide wheels 304; the plurality of guide wheels 304 are arranged at intervals around the edge of the molding die 2, and one end of each guide wheel 304 is vertically and rotatably connected to the surface of the molding die 2; the conveyor belt 301 is commonly connected to the outside of the plurality of guide wheels 304, and straight teeth are provided on the surfaces of the guide wheels 304 in contact with the conveyor belt 301 for power transmission; the outer surface of the conveyor belt 301 also abuts against a plurality of guide posts 18 fixedly connected to the surface of the molding die 2; any one of the guide wheels 304 is connected to a driving motor (not shown in the figure) that drives it to rotate, and the conveyor belt 301 rotates counterclockwise under the drive of the guide wheels 304; the driving motor is fixed on the surface of the molding machine body 1; the plurality of rolling rollers 302 and smoothing housings 303 are arranged alternately at intervals on the surface of the conveyor belt 301 and abut against the surface of the canal; the rolling rollers 302 are all rotatably mounted above the conveyor belt 301, and a driven gear 4 is connected to one end of the rolling roller 302 close to the molding die 2; a first rack 5 is provided at the edge of the molding die 2 close to the surface of the canal; the driven gear 4 meshes with the first rack 5, so that the rolling roller 302 rotates on its own while moving with the conveyor belt 301; at least two arc-shaped movable blocks 6 are rotatably connected to one end of the rolling roller 302 away from the molding die 2; the movable blocks 6 are arranged at intervals around the rolling roller 302 in the circumferential direction, and an actuating assembly 7 for driving their movement is connected; the actuating assembly 7 is arranged at the end face of the rolling roller 302. When a expansion joint needs to be made, the actuating assembly 7 makes the free ends of the movable blocks 6 extend out of the surface of the rolling roller 302 and cut a seam on the surface of the canal; a protective cover 20 covering the integral smoothing and cutting assembly 3 is also provided on the surface of the molding die 2.

[0032] In this solution, the protective cover 20 is fixedly connected to the forming die by bolts. The protective cover 20 is used to cover the leveling and cutting integrated component 3 to prevent foreign objects from falling into the interior and affecting the normal operation of the machine. The free end of the guide wheel 304 is rotatably connected to the inner surface of the protective cover 20, improving the stability during movement. When forming a water channel, the water channel forming machine is hoisted above the dug water ditch, and the hopper is filled with concrete. When the forming machine body 1 completes the forming of the first section of the water channel and moves to the next working station, the concrete in the hopper will enter the forming die 2 at this time. The vibrating device on the surface of the forming die 2 vibrates the entering concrete (the working process of the existing water channel forming machine will not be elaborated in detail). During the period when the concrete is being vibrated, the forming machine body 1 will not move, enabling the leveling and cutting integrated component 3 to level or cut the joints of the previously formed water channel. Start the drive motor, and the drive motor drives the conveyor belt 301 to rotate counterclockwise through the guide wheel 304. While the conveyor belt 301 is rotating, it drives the rolling roller 302 and the leveling housing 303 mounted on its surface to move together. Since multiple guide wheels 304 are arranged along the edge of the forming die 2, the movement trajectory of the conveyor belt 301 can cover the upper surface of the water channel, and the leveling housing 303 and the rolling roller 302 can compact and level the surface of the water channel. Since the leveling housing 303 will abut against the surface of the water channel for leveling during movement, it may disturb the upper surface of the water channel. Therefore, the rolling roller 302 compacts the leveled surface of the water channel, and the rolling roller 302 will rotate automatically while moving with the conveyor belt 301, further improving the leveling effect of the water channel surface. Moreover, the multiple staggered leveling housings 303 and rolling rollers 302 can perform multiple repetitive operations on the water channel surface, improving the quality and efficiency of leveling the water channel surface, eliminating the need for manual leveling by workers, and reducing the burden on workers and construction costs. The ends of the leveling housing 303 and the rolling roller 302 close to the forming die 2 are provided with rounded corners to prevent the end faces of the leveling housing 303 and the rolling roller 302 from abutting against the concrete on the surface of the water channel when the forming machine body 1 completes vibration and moves to form the next section of the water channel. Additionally, the widths of the conveyor belt 301, the leveling housing 303, and the rolling roller 302 are greater than the width of the forming machine body 1 for one section of the water channel to prevent the working range of the leveling housing 303 and the rolling roller 302 from not completely covering the surface of the water channel;

[0033] When the main body 1 of the forming machine needs to move a certain distance to make a expansion joint, start the execution component 7 and make the movable block 6 move. The free end of the movable block 6 extends out of the surface of the rolling roller 302 and cuts a slot on the surface of the water channel. Since the rolling roller 302 will rotate, the rolling roller 302 will drive a plurality of movable blocks 6 to rotate simultaneously. As shown in the figure, the arc-shaped movable block 6 is inserted into the surface of the water channel and takes away the redundant concrete, realizing the slot cutting on the surface of the water channel. A plurality of rolling rollers 302 and the movable blocks 6 arranged on their surfaces can cut a standard expansion joint. Compared with the expansion joint formed by extrusion, the expansion joint made by the rotation of a plurality of movable blocks 6 has a uniform width, does not squeeze the surfaces of the water channel on both sides of the expansion joint, ensures the flatness of the surface of the water channel, and does not require the staff to move the corresponding cutting device, which is time-consuming and laborious, and also reduces the cost of purchasing construction equipment. The whole operation process is simple and fast, the operation is simple, and the slot cutting and leveling construction steps can be carried out simultaneously, greatly improving the construction efficiency.

[0034] In this embodiment, first brackets 13 are respectively arranged between the two ends of the rolling roller 302 and the conveyor belt 301, and the rolling roller 302 is rotatably connected with the first brackets 13; the execution component 7 includes a toothed disc 702, a rotating rod 701, a first gear 703 and a second gear 704; the rotating rod 701 is coaxially and rotatably connected to the end surface of the rolling roller 302 on the side away from the forming die 2, and the end of the rotating rod 701 away from the rolling roller 302 passes through the first bracket 13; the first gear 703 is elastically slid along its axial direction on the surface of the rotating rod 701, and the first gear 703 is arranged on the side of the first bracket 13 away from the rolling roller 302; a first electromagnet 10 is arranged on the surface of the first bracket 13 close to the first gear 703; the toothed disc 702 is sleeved on the surface of the rotating rod 701 and is arranged between the first bracket 13 and the rolling roller 302, and the rotating rod 701 drives the toothed disc 702 to rotate; the ends of the movable blocks 6 are all fixed with the second gears 704 meshing with the toothed disc 702; the second gears 704 are arranged at the rotation centers of the movable blocks 6, and a torsion spring is arranged at the connection between the movable blocks 6 and the rolling roller 302; a limiting component 8 for fixing the rotation of the movable blocks 6 is also arranged on the surface of the first bracket 13; a second rack 12 meshing with the first gear 703 is also arranged on the inner surface of the protective cover 20.

[0035] Combined with Figure 2 As shown, the second rack 12 is arranged inside the protective cover 20 and is fixedly connected thereto, and there is only a small section; a spring is arranged between the first gear 703 and the surface of the first bracket 13. Combined with Figure 9As shown, when the movable block 6 does not need to cut a slit, the first electromagnet 10 is energized, the first gear 703 is close to the surface of the bracket (the first gear 703 will not mesh with the second rack 12 at this time), and the movable block 6 is fixed to the end surface of the rolling roller 302 under the action of the limit assembly 8 and will not extend out. When it is necessary to cut a slit on the surface of the canal, the limit assembly 8 releases the restriction on the movable block 6, and the movable block 6 rotates under the action of the torsion spring and extends outwardly to the outer surface of the rolling roller 302. After rotating a certain distance, the limit assembly 8 fixes the movable block 6 again. When the movable block 6 is in an arc shape, and the rolling roller 302 rotates counterclockwise (combined with the counterclockwise rotation of the conveyor belt 301 in the figure), the movable block 6 will remain in an extended state under the action of the torsion spring (the centrifugal force generated when the rolling roller 302 rotates will also keep the movable block 6 in an extended state), and will not rotate during the process of cutting the surface of the water channel, so that the concrete on the surface of the water channel can be stably planed out; when it is necessary to retract the extended movable block 6, the first electric The magnet 10 is powered off, and the first gear 703 slides along its axial direction under the action of the spring and abuts against the end face of the rotating rod 701. When the rolling roller 302 moves to the position of the second rack 12 driven by the conveyor belt 301, the first gear 703 just meshes with the second rack 12, and the limit assembly 8 releases the restriction on the movable block 6. During the movement of the rolling roller 302 along the conveyor belt 301, the first gear 703 drives the rotating rod 701 to rotate under the action of the second rack 12, and the rotating rod 701 drives the toothed disc 702 to rotate. 702 rotates clockwise and drives the second gear 704 to rotate counterclockwise until the movable block 6 is reset, and the first gear 703 is no longer engaged with the second rack 12, and the limit assembly 8 fixes the movable block 6 again. The movable block 6 can be quickly and automatically retracted and extended simply by controlling the first electromagnet 10 and the limit assembly 8, thereby realizing the production of expansion joints and reducing production costs. It will not affect the working process of the rolling roller 302 and the smoothing shell 303, greatly reducing the construction steps for the staff to make expansion joints and improving the construction speed.

[0036] In this embodiment, the limit assembly 8 includes a support block 801, a limit block 802 and a second electromagnet; the support block 801 is fixed to a side surface of the first bracket 13 close to the toothed disc 702; the limit block 802 is elastically penetrated through the surface of the support block 801 along the vertical direction, and a second electromagnet is provided on the side surface of the support block 801 close to the limit block 802; a plurality of limit grooves 803 are circumferentially provided on the surface of the rotating rod 701 and are mutually engaged with the limit block 802, and the plurality of limit grooves 803 are evenly spaced.

[0037] Combination Figure 8As shown, when the second electromagnet is powered off (the second electromagnet is blocked by the limiting block), the limiting block 802 is engaged with the limiting groove 803 on the rotating rod 701, thereby restricting the rotation of the gear disk 702 and fixing the movable block 6 in the current position. When the second electromagnet is powered on, it will adsorb the limiting block 802. After the limiting block 802 moves upward, it no longer engages with the limiting groove 803. At this time, the movable block 6 can be extended under the action of the torsion spring. The gear disk 702 drives the rotating rod 701 to rotate. By controlling the engagement of the limiting block 802 with different limiting grooves 803, the movable block 6 can be fixed at different angles, thereby controlling the length of the movable block 6 extending out of the rolling roller 302 and making expansion joints of different depths, improving the applicable range of the device when making expansion joints. And a blocking rod 9 is also provided at the end face of the rolling roller 302. When the distance that the movable block 6 extends out of the rolling roller 302 reaches the maximum value, the blocking rod 9 can just hold it against, preventing the movable block 6 from rotating excessively and further improving the stability of the movable block 6 during movement.

[0038] In this embodiment, one end of the rotating rod 701 also slidably penetrates into the interior of the rolling roller 302; the rolling roller 302 is composed of a rolling roller a 3021 and a rolling roller b 3022 that slide relative to each other and are coaxially arranged; the end face of the rolling roller b 3022 away from the rolling roller a 3021 is provided with the actuating assembly 7; one end of the rotating rod 701 penetrates through the rolling roller b 3022 and the gear disk 702; a servo motor 23 is coaxially arranged inside the rolling roller b 3022; the output end of the servo motor 23 is connected to a lead screw 22, and the free end of the lead screw 22 penetrates into the rolling roller a 3021, and the lead screw 22 is threadedly connected to the rolling roller a 3021.

[0039] Combined with Figure 10As shown, the rolling roller a3021 and the rolling roller b3022 are connected by a plurality of circumferentially arranged connecting columns. The left end of the connecting column is fixed to the end face of the rolling roller a3021, and the other end slides through the rolling roller b3022. The servo motor 23 can drive the rolling roller b3022 to reciprocate axially along its axis through the cooperation with the lead screw 22, so as to control the lateral contact position between the movable block 6 and the surface of the water channel. When any two adjacent rolling rollers 302 cooperate with each other, for example, one of the rolling roller b3022 moves axially a certain distance away from the rolling roller a3021, and the rolling roller b3022 on any adjacent rolling roller 302 remains stationary. The working routes of the movable blocks 6 on the two rolling rollers 302 are parallel to each other on the same horizontal plane (a part of the working routes passed by the movable blocks 6 on the two rolling rollers 302 overlaps), and a expansion joint wider than the width of the movable block 6 can be cut. Also, by adjusting the positions of multiple rolling roller b3022, the production of expansion joints with various widths can be realized, further improving the applicable range of the device when making expansion joints and greatly improving the working efficiency of making expansion joints. And after the rolling roller b3022 moves away from the rolling roller a3021, a gap will be formed between its adjacent end faces. Since the rolling roller b3022 on any adjacent rolling roller 302 remains stationary, this vacated gap will be rolled, so there will be no rolling dead angle, ensuring that the surface of the water channel is within the working range of the rolling roller 302.

[0040] In this embodiment, an opening is provided on one side of the leveling housing 303 that pushes the concrete on the surface of the water channel; second brackets 21 are provided between the two ends of the leveling housing 303 and the conveyor belt 301; rotating shafts rotatably connected to the second brackets 21 are provided at both ends of the leveling housing 303, and torsion springs are provided between the rotating shafts and the second brackets 21; a vertically arranged abutting block 11 is fixed to the surface of the rotating shaft, and the abutting block 11 is arranged on the surface of the rotating shaft away from the forming die 2; a connecting rod 14 is vertically provided at one end of the rotating shaft close to the forming die 2; a roller 15 with a diameter larger than the tooth pitch of the first rack 5 is rotatably connected to the end of the connecting rod 14 away from the rotating shaft, and when the roller 15 abuts against the first rack 5, the opening of the leveling housing 303 is perpendicular to the surface of the water channel; a first stop block 16 for blocking the abutting block 11 is fixed to the surface of the second bracket 21, and when the roller 15 does not abut against the first rack 5, the opening of the leveling housing 303 faces the conveyor belt 301, and the abutting block 11 abuts against the first stop block 16; a plurality of through holes corresponding to the leveling housing 303 one by one are also provided on the surface of the conveyor belt 301; a collecting frame 17 is provided on the surface of the forming die 2; one end of the first rack 5 extends to the side close to the collecting frame 17.

[0041] Combined Figure 3 and Figure 6As shown, the first rack 5 not only drives the rolling roller 302 to rotate, but also abuts against the leveling housing 303. Since the diameter of the roller 15 is greater than the adjacent tooth pitch of the first rack 5, the roller 15 will not bounce when abutting against the first rack 5 during movement, enabling the leveling housing 303 to move stably. When the movable block 6 makes a cut on the surface of the water channel, the concrete carried out by the rotation of the movable block 6 will accumulate on the surface of the water channel. The leveling housing 303 can collect the concrete accumulated on the surface of the water channel during movement. When the roller 15 connected to the leveling housing 303 abuts against the first rack 5, combined with Figure 4 As shown, the opening of the leveling housing 303 is perpendicular to the surface of the water channel, ensuring that while the leveling housing 303 levels the surface of the water channel, it can also collect the accumulated concrete (the length of the leveling housing 303 is greater than the maximum extended length of the rolling roller 302, ensuring that the leveling housing 303 can collect the concrete carried out by the movable block 6). When the roller 15 is no longer in contact with the first rack 5, combined with Figure 4 , Figure 5 As shown, the leveling housing 303 rotates under the action of the torsion spring until the abutting block 11 on the rotating shaft abuts against the first stop block 16. At this time, the opening direction of the leveling housing 303 faces the surface of the conveyor belt 301. At this time, the leveling housing 303 is exactly above the collection box 17. The concrete collected in the leveling housing 303 passes through the through hole and falls into the collection box 17, emptying the concrete in the collection box 17 to prevent excessive accumulation of the concrete inside, which can no longer collect the concrete accumulated on the surface of the water channel and affect the leveling effect of the water channel surface, and also reduce the waste of concrete.

[0042] In this embodiment, at least two second stop blocks 19 are provided on the surface of the forming die 2; the second stop blocks 19 are arranged above the conveyor belt 301 and are used to block the roller 15 to deflect the leveling housing 303; any one of the guide posts 18 is arranged between the two second stop blocks 19, and the guide post 18 is arranged on the upper surface of the conveyor belt 301, making the conveyor belt 301 above the collection box 17 inclined towards the upper surface of the collection box 17.

[0043] Combined with Figure 2 As shown, corresponding guide posts 18 are also provided inside the protective cover 20, enabling the conveyor belt 301 to operate stably, playing a role in limiting and tensioning the conveyor belt 301. Any one of the guide posts 18 is arranged between the two second stop blocks 19, combined with Figure 6As shown in the figure, the guiding column 18 is located below the second stop block 19, and abuts against the conveyor belt 301 below the second stop block 19 to form a V shape. When the roller 15 connected to the leveling housing 303 leaves the first rack 5 and contacts the second stop block 19, the second stop block 19 abuts against the roller 15 to cause the leveling housing 303 to rotate clockwise by a certain distance, so that the torsion spring is compressed and stores elastic potential energy. Since the second stop block 19 has only one section, when the roller 15 no longer abuts against the second stop block 19, the elastic potential energy stored in the torsion spring causes the leveling housing 303 to reset more quickly, and the rotating shaft of the leveling housing 303 will have a more violent impact with the first stop block 16, causing the leveling housing 303 to vibrate violently, shaking out the concrete that has not been poured out inside, preventing the concrete from adhering to the surface of the leveling housing 303. Moreover, the V-shaped conveyor belt 301 below the second stop block 19 can enable the concrete to concentrate and pass through the through hole and fall into the collection box 17, improving the efficiency of pouring out the concrete from the leveling housing 303 and ensuring that the leveling housing 303 has enough space to collect the concrete accumulated on the surface of the water channel, thereby ensuring the leveling effect of the water channel surface; to facilitate taking out the concrete in the collection box 17, through holes are provided on the surface of the protective cover 20, which is convenient for the staff to observe the situation in the collection box 17, take out the concrete in time, and prevent the occurrence of concrete overflow. Moreover, the taken-out concrete can be put back into the hopper of this water channel forming machine for reuse, reducing the waste of concrete.

[0044] In this embodiment, the first bracket 13 includes a first slider and a second slider that are elastically slidably connected to each other, so that the rolling roller 302 applies a certain pressure to the surface of the water channel, improving the compaction effect of the rolling roller 302 on the surface of the water channel.

[0045] The working process of the present invention is as follows:

[0046] Before the construction of the water channel, first use a self-made shaping bucket to excavate the water channel, and the water channel is formed in one go. Then, hoist and place this water channel forming machine on the upper surface of the excavated water channel. Transport the mixed concrete to the hopper of this water channel forming machine through a concrete delivery truck, start this water channel forming machine, and start the formation of the first section of the water channel;

[0047] After the formation of the water channel in the first section is completed, the water channel forming machine moves to the next working station. At this time, the concrete in the hopper enters the forming die 2, and the vibrating device on the surface of the forming die 2 vibrates the entering concrete. During the period when the concrete is being vibrated, the main body 1 of the forming machine does not move. At this time, the leveling and cutting integrated component 3 is started, and the driving motor drives the conveyor belt 301 to rotate counterclockwise. The leveling housing 303 and the rolling roller 302 move synchronously with the conveyor belt 301 and level and compact the surface of the water channel. Multiple leveling housings 303 and rolling rollers 302 reciprocate on the surface of the water channel, improving the smoothness and flatness of the water channel surface, greatly improving the construction efficiency during the leveling of the water channel, and reducing the loss of manpower and material resources;

[0048] When the water channel forming machine has completed the formation of the water channel for a certain distance and a expansion joint needs to be made, the second electromagnet is powered off, and the movable block 6 unfolds under the action of the torsion spring and protrudes from the surface of the rolling roller 302. When the movable block 6 rotates by a corresponding angle, the second electromagnet is powered on, and the movable block 6 rotates with the rolling roller 302 and cuts the surface of the water channel to form an expansion joint. The width of the expansion joint during production can also be adjusted by the servo motor 23. The excess concrete cut out will be collected inside the leveling housing 303. When the leveling housing 303 moves above the collection box 17, it will automatically pour the accumulated concrete inside into the collection box 17 to prevent the collection box 17 from being filled with concrete; when the production of the expansion joint is completed and the movable block 6 needs to be retracted, the first electromagnet 10 is powered off, and then the second electromagnet is powered off. When the rolling roller 302 moves to the second rack 12, the first gear 703 meshes with the second rack 12 and drives the movable block 6 to reset. The second electromagnet is controlled to be powered on again to fix the movable block 6; when the expansion joint needs to be made again, the above process is repeated; realizing the automated work of the expansion joint and the leveling of the water channel surface, greatly reducing the burden on construction workers and improving the construction speed.

[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
