Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a canal segment forming device. Background Technology

[0002] Water conservancy construction requires the use of canal segments, which are made of concrete and cast in segment molds. The production process usually includes: mold cleaning, applying release agent, placing the steel cage into the mold, installing embedded parts, pouring, vibration, steam curing, demolding and water curing. The steel cage is usually placed into the mold by hoisting.

[0003] Chinese patent CN222060725U discloses a segment mold precision adjustable mechanism. This mechanism can achieve adjustable mold precision while significantly reducing costs and improving the segment qualification rate. However, according to the water channel segment forming device provided by related technologies and existing technologies, there is a lack of limiting the position of the steel cage during the hoisting and placement of the steel cage into the mold. The steel cage is prone to deviation when it is placed, which affects the segment forming quality. At the same time, the steel cage is also prone to shaking during hoisting, which may cause it to come into contact with the side wall of the mold during the descent, resulting in scratches and damage to the mold, affecting the mold precision and segment forming quality. In addition, the front and rear side molds and the side molds are connected and fixed by bolts. During the subsequent concrete vibration stage, the bolts are prone to loosening due to vibration, causing concrete leakage. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a water channel segment forming device.

[0005] The purpose of this utility model is achieved through the following technical solution: a water channel segment forming device, including a support frame, a mold fixedly mounted on the support frame, cover plates rotatably mounted on both sides of the top of the support frame, a transmission component mounted on the support frame at a position outside the mold, four limiting components for reinforcing the mold mounted on the transmission component, the four limiting components being distributed at positions corresponding to the four corners of the mold, and a control component for locking the position of the limiting components being provided at one corner of the transmission component.

[0006] Preferably, the transmission assembly includes a drive shaft that is rotatably mounted longitudinally on one side of the top of the support frame. Two worm gears are symmetrically fixed on the drive shaft. A rotating shaft is rotatably mounted on the support frame above the two worm gears. The rotating shaft is arranged laterally, and a worm wheel is fixed on the rotating shaft at a position corresponding to the two worm gears.

[0007] Preferably, the limiting assembly includes a fixed sleeve fixed to the rotating shaft, a top plate fixedly mounted on the fixed sleeve, a first limiting plate fixedly mounted on the end of the top plate away from the fixed sleeve, a second limiting plate fixedly mounted on the first limiting plate, and several guide rollers rotatably mounted on the side of the first limiting plate and the second limiting plate facing the inside of the mold.

[0008] Preferably, the control component includes a handle fixed to the front end of the drive shaft, a control rod slidably mounted on the end of the handle away from the drive shaft, a plug fixedly provided at the rear end of the control rod, and a socket provided on the support frame at a position corresponding to the plug.

[0009] Preferably, the top plate is L-shaped, and the distance between its top surface and the rotating shaft is equal to the distance between the rotating shaft and the mold.

[0010] Preferably, the top of the first limiting plate is provided with a sloping surface, and the bottom of the first limiting plate is arc-shaped and higher than the steel cage placed inside the mold.

[0011] Preferably, the top of the second limiting plate is provided with a sloping surface, and the top of the second limiting plate is flush with the top surface of the top plate.

[0012] Beneficial effects:

[0013] This canal segment forming device, through the setting of limiting components, transmission components, and control components, ensures that the reinforcing cage falls into the mold under the restriction of the first and second limiting plates. This ensures that the reinforcing cage falls accurately into the middle position of the mold, guaranteeing the precision of the reinforcing cage installation and preventing the reinforcing cage from contacting the mold and scratching the inner wall of the mold, thereby ensuring the mold accuracy and improving the segment forming quality. At the same time, the top plate uses the front and rear side molds to tighten the mold and locks them with inserts, reinforcing the connection between the mold side molds. In the subsequent vibration stage, even if the connecting bolts between the front and rear side molds and the side molds loosen due to vibration, the top plate can still ensure the tightness of the connection between the front and rear side molds and the side molds, preventing concrete leakage and ensuring the segment forming quality.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0025] like Figures 1 to 7As shown, a water channel segment forming device includes a support frame 1, on which a mold 2 is fixedly mounted. Cover plates 3 are rotatably mounted on both sides of the top of the support frame 1. A transmission assembly 5 is installed on the support frame 1 outside the mold 2. Four limiting components 4 for reinforcing the mold 2 are installed on the transmission assembly 5, distributed at positions corresponding to the four corners of the mold 2. A control component 6 for locking the position of the limiting components 4 is provided at one corner of the transmission assembly 5. When the reinforcing cage is hoisted into the mold, it is positioned above the rectangular space enclosed by the four limiting components 4, and then the reinforcing cage is slowly... The steel cage is lowered into the mold 2 under the constraint of four limiting components 4, positioning the steel cage while preventing it from contacting the side wall of the mold 2. This avoids the steel cage shaking and scratching the mold 2, improving the quality of the segment forming. After the steel cage enters the mold, the control component 6 controls the transmission component 5 to rotate the four limiting components 4 outward by 270 degrees, pressing them tightly against the front and rear sides of the mold 2. This makes the connection between the side molds of the mold 2 tighter, reinforcing the mold 2 and improving its stability. Finally, the two cover plates 3, supported by the support frame 1, cover the top sides of the mold 2 for subsequent steps.

[0026] like Figures 1 to 4 As shown, the transmission assembly 5 includes a drive shaft 501 that is rotatably mounted longitudinally on one side of the top of the support frame 1. Two worm gears 502 are symmetrically fixed on the drive shaft 501. A rotating shaft 504 is rotatably mounted on the support frame 1 above the two worm gears 502. The rotating shaft 504 is arranged laterally, and a worm wheel 503 is fixed on the rotating shaft 504 at a position corresponding to the two worm gears 502. The control assembly 6 drives the two worm gears 502 to rotate through the drive shaft 501. The worm gears 502 mesh with the worm wheels 503 to drive the four limit components 4 on the two rotating shafts 504 to rotate outward synchronously. At the same time, the control assembly 6 controls the four limit components 4 to switch states.

[0027] like Figures 1 to 7As shown, the limiting assembly 4 includes a fixed sleeve 401 fixed to the rotating shaft 504, a top plate 402 fixedly mounted on the fixed sleeve 401, a first limiting plate 403 fixedly mounted on the end of the top plate 402 away from the fixed sleeve 401, and a second limiting plate 404 fixedly mounted on the first limiting plate 403. Twenty guide rollers 405 are rotatably mounted on the side of both the first limiting plate 403 and the second limiting plate 404 facing the inner side of the mold 2. The top plate 402 is L-shaped, and the distance between its top surface and the rotating shaft 504 is equal to the distance between the rotating shaft 504 and the mold 2. The tops of the first limiting plate 403 and the second limiting plate 404 are both provided with sloping surfaces. The bottom of the first limiting plate 403 is arc-shaped and slightly higher than the reinforcing cage placed inside the mold 2. The top of the second limiting plate 404 is flush with the top surface of the top plate 402. When the reinforcing cage is hoisted into the mold, it is positioned above the rectangular space enclosed by the four first limiting plates 403 and the four second limiting plates 404. Then, it is slowly lowered. Since the two sides of the reinforcing cage are sloping, they will not contact the second limiting plates 404 at first. The front and rear sides of the reinforcing cage will first contact the second limiting plate 404. Guided by the top slope of the first limiting plate 403, the steel cage enters between the four first limiting plates 403 and gradually falls under their restriction. As the steel cage falls, the tops of the slopes on both sides of the steel cage will enter between the four second limiting plates 404 under the guidance of the top slope of the second limiting plate 404 and fall into the mold 2 under their restriction. During this process, the guide rollers 405 on the first limiting plates 403 and the second limiting plates 404 can reduce the resistance of the steel cage falling. The steel cage will fall under the restriction of the first limiting plates 403 and the second limiting plates 404 to... Inside mold 2, the reinforcing cage is positioned, and it is restricted from contacting the side wall of mold 2, thus preventing the reinforcing cage from shaking and scratching mold 2, thereby improving the quality of segment forming. After the reinforcing cage is in place, the two rotating shafts 504 drive the four top plates 402 to rotate outward by 270 degrees through the fixed sleeve 401, so that the top surface of the top plate 402 contacts the front and rear side molds of mold 2. At this time, the top plate 402 can press against the front and rear side molds of mold 2 with the support of the rotating shafts 504, making the connection between the side molds tighter and thus reinforcing mold 2.

[0028] like Figures 2 to 7As shown, the control assembly 6 includes a handle 601 fixed to the front end of the drive shaft 501. A control lever 602 is slidably mounted on the end of the handle 601 away from the drive shaft 501. A plug 603 is fixedly provided at the rear end of the control lever 602. A socket 604 is provided on the support frame 1 at a position corresponding to the plug 603. Holding the control lever 602 drives the drive shaft 501 to rotate through the handle 601, thereby driving the two shafts 504 to rotate through the worm gear 502 meshing with the worm wheel 503, switching the state of the top plate 402. When the top plate 402 rotates 270 degrees, the insert block 603 corresponds exactly to the insertion hole 604. At this time, the control rod 602 slides backward, thereby driving the insert block 603 to be inserted into the insertion hole 604, locking the position of the rotating handle 601, and thus locking the drive shaft 501. In the subsequent vibration stage, even if the connecting bolts between the side molds of the mold 2 become loose, the top plate 402 can still press the mold 2 tightly, keeping the connection between the side molds of the mold 2 tight, improving the stability of the mold 2, and preventing concrete leakage.

[0029] The work process is as follows:

[0030] S1: As Figures 1 to 3 As shown, when the steel cage is hoisted into the formwork, it is positioned above the rectangular space enclosed by four first limiting plates 403 and four second limiting plates 404, and then it is controlled to fall slowly.

[0031] S2: As Figures 1 to 3 As shown, since the two sides of the steel cage are inclined, it will not contact the second limiting plate 404 at the beginning. The front and rear sides of the steel cage will first enter between the four first limiting plates 403 under the guidance of the top inclined surface of the first limiting plate 403, and gradually fall under its restriction.

[0032] S3: As Figures 1 to 3 As shown, as the steel cage falls, the top of the inclined surfaces on both sides of the steel cage will enter between the four second limiting plates 404 under the guidance of the top inclined surface of the second limiting plate 404, and fall into the mold 2 under its restriction.

[0033] S4: As Figures 1 to 3 As shown, the guide rollers 405 on the first limiting plate 403 and the second limiting plate 404 can reduce the resistance of the steel cage falling. Finally, the steel cage falls into the mold 2 under the restriction of the first limiting plate 403 and the second limiting plate 404, realizing the positioning of the steel cage. At the same time, the steel cage will not contact the side wall of the mold 2, thereby avoiding the steel cage shaking and scratching the mold 2, and thus improving the quality of the tube segment forming.

[0034] S5: As Figures 1 to 7As shown, after the steel cage is placed into the mold, the hand holds the control lever 602 and drives the drive shaft 501 to rotate through the handle 601. This drives the two rotating shafts 504 to rotate through the worm gear 502 meshing with the worm wheel 503, causing the four top plates 402 to rotate outward by 270 degrees. The top surface of the top plate 402 is rotated to contact the front and rear side molds of the mold 2. At this time, the top plate 402 can press against the front and rear side molds of the mold 2 with the support of the rotating shaft 504, making the connection between the side molds tighter and thus strengthening the mold 2.

[0035] S6: As Figures 2 to 7 As shown, the control lever 602 slides backward, thereby driving the insert block 603 to be inserted into the insert hole 604, locking the position of the rotating handle 601, and thus locking the drive shaft 501. In the subsequent vibration stage, even if the connecting bolts between the side molds of the mold 2 become loose, the top plate 402 can still press against the mold 2, keeping the connection between the side molds of the mold 2 tight, improving the stability of the mold 2, and preventing concrete leakage.

[0036] S7: As Figure 6 As shown, finally, the cover plate 3 is placed on both sides of the top of the mold 2 under the support of the support frame 1, and then the pouring, vibration, steam curing, demolding and water curing are carried out in sequence to finally complete the segment molding.

[0037] The mold 2 in this application is a well-known technology in this field, therefore its specific structure and working principle are not described in detail.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
