Description

[0003] When using the pouring machine, workers need to be equipped with auxiliary tools to evenly spread the concrete discharged by the pouring machine in the double T-plate mold. Due to the uncertainty of manual operation, not only will the uniformity of the concrete in the double T-plate mold be affected, resulting in fluctuations in construction quality and affecting the overall performance and appearance quality of the double T-plate, but also for the workers, holding auxiliary tools for a long time to spread the concrete in the double T-plate mold is a physically demanding job, which will cause fatigue to the workers, and thus affect construction efficiency and safety;

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a large-span prestressed concrete double T-plate pouring machine, which has the following beneficial effects:

This not only ensures the uniform distribution of concrete in the mold body, but also avoids the problems of uneven concrete thickness and uneven surface caused by improper manual operation, thereby improving the overall performance quality and appearance of the double T-plate, and can also reduce the labor intensity of the staff, reduce the risk of misoperation, make the construction process easier, and improve the safety of the staff during the construction process.

[0022] 3.

[0023] 4. The partitions set up can separate the concrete leveling area and the vibration area, which not only ensures that the concrete can be vibrated immediately after leveling, avoiding the performance changes of the concrete during a long waiting period, but also the spreading plate and the vibration plate can be operated independently without interfering with each other, thereby significantly improving the construction efficiency and reducing the overall construction time.

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] A large-span prestressed concrete double T-plate pouring machine of this embodiment, such as Figure 1 - Figure 8 As shown, it includes a mold body 1, the upper end surface of the mold body 1 is fixedly connected to a mounting frame 2, a pouring funnel 3 is horizontally slidably connected to the mounting frame 2, the lower end surface of the pouring funnel 3 is fixedly connected to a pouring pipe 4, the lower end of the outer surface of the pouring pipe 4 is fixedly connected to a mounting plate 5, a through groove 6 is opened on the mounting plate 5, and an automatic concrete leveling mechanism 7 is arranged on the mounting plate 5, and the automatic concrete leveling mechanism 7 is used to automatically and evenly level the concrete discharged from the pouring pipe 4 in the mold.

[0038] In this embodiment, Figure 4 As shown, the automatic concrete leveling mechanism 7 includes a slide plate 709, which is slidably connected in the through groove 6, and a movable plate 707 is fixedly connected to the upper end surface of the slide plate 709. A movable groove 708 is provided on the upper end surface of the movable plate 707, and a spreading plate 710 is fixedly connected to the lower end surface of the slide plate 709. When the movable plate 707 is driven by force to slide back and forth in the through groove 6, the spreading plate 710 below can be driven to move synchronously and reciprocatingly horizontally to level the concrete inside the mold body 1.

[0039] In this embodiment, Figure 3 and Figure 4 As shown, the automatic concrete leveling mechanism 7 also includes a support frame 701, which is fixedly connected to the upper end surface of the mounting plate 5, and the lower end surface of the support frame 701 is symmetrically rotatably connected to a sprocket 702, one of the sprockets 702 is fixedly connected to a driving motor, a chain 703 is sleeved between the outer surfaces of the sprockets 702, and a linkage column 706 is fixedly connected to the lower end surface of the chain 703, and the linkage column 706 is slidably connected in a moving groove 708. When the driving motor is turned on to drive one of the sprockets 702 to rotate, the chain 703 can move around the outer surfaces of the two sprockets 702 by cooperating with the other sprocket 702, and drive the linkage column 706 connected to the lower end surface of the chain 703 to move synchronously, while driving the linkage column 706 to slide in the moving groove 708 opened on the upper end surface of the moving plate 707, pushing the moving plate 707 to move horizontally.

[0040] In this embodiment, Figure 4 and Figure 5As shown, a connecting groove 711 is provided on the spreading plate 710, and a connecting block 713 is slidably connected in the connecting groove 711, and push plates 712 are fixedly connected on both sides of the connecting block 713, and a push rod 716 is rotatably connected to the side of the pushing plate 712 away from the connecting block 713, and the push rod 716 is rotatably connected to the side of the pushing plate 712 away from the pushing plate 712. The fixed block 715 is fixedly connected to an elastic telescopic column 714 on the side close to the spreading plate 710, and the elastic telescopic column 714 is fixedly connected to the side wall of the spreading plate 710. When the fixed block 715 is forced to approach the spreading plate 710 and squeeze the elastic telescopic column 714, the push rod 716 can drive the pushing plate 712 to slide horizontally on the side wall of the spreading plate 710, thereby pushing the concrete accumulated on the side wall of the spreading plate 710 to the internal gap of the front mold body 1.

[0041] In this embodiment, Figure 5 As shown, a limit block 705 is provided on the side of the fixed block 715 away from the elastic telescopic column 714, and a partition 704 is fixedly connected between the limit blocks 705. The partition 704 is fixedly connected to the lower end surface of the mounting plate 5. When the fixed block 715 moves horizontally and approaches the limit block 705, it will be hindered by the limit block 705. In addition, the set partition 704 can separate the concrete flattening area and the vibration area, thereby ensuring that the concrete can be vibrated immediately after being flattened, avoiding the performance changes of the concrete during a long waiting process.

[0042] In the prior art, workers need to be equipped with auxiliary tools to evenly spread the concrete discharged by the pouring machine in the double T-plate mold. Due to the uncertainty of manual operation, not only will the uniformity of the concrete in the double T-plate mold be affected, resulting in fluctuations in construction quality and affecting the overall performance and appearance quality of the double T-plate, but also for the workers, holding auxiliary tools for a long time to spread the concrete in the double T-plate mold is a physically demanding job, which will cause fatigue to the workers and further affect the construction efficiency and safety. Compared with the prior art, the concrete can be automatically evenly spread in the mold body 1 during the process of pouring concrete into the mold body 1, which can not only ensure the uniform distribution of the concrete in the mold body 1, but also avoid the problems of uneven thickness and uneven surface of the concrete caused by improper manual operation, thereby improving the overall performance quality and appearance of the double T-plate, but also can reduce the labor intensity of the workers, reduce the risk of misoperation, make the construction process easier, and improve the safety of the workers during the construction process;

[0043] Secondly, by means of the set limit block 705, when the spreading plate 710 pushes the concrete to both sides of the mold body 1, the pushing plate 712 can be automatically driven to push the excess concrete pushed out by the spreading plate 710 into the mold body 1 in the front, thereby avoiding the excess concrete from spilling out of the mold body 1. This not only ensures that the concrete is fully utilized in the mold body 1, reducing the waste caused by spilling, thereby reducing construction costs, but also maintains the cleanliness of the construction site, improves the construction environment, avoids the hidden dangers of tripping or slipping caused by spilled concrete at the construction site, and further improves the safety of workers during the construction process.

[0044] In other aspects, this embodiment also provides a concrete vibrating mechanism 8 for compacting the flattened concrete, such as Figure 6 - Figure 8 As shown, the concrete vibrating mechanism 8 includes a vibrating plate 803 , and the upper end surface of the vibrating plate 803 is symmetrically fixedly connected with a sliding column 802 , and the sliding column 802 is slidably connected to the mounting plate 5 , and a cross plate 801 is fixedly connected between the upper end surfaces of the mounting plate 5 .

[0045] In this embodiment, Figure 8 As shown, a sliding groove 810 is provided on the side of the horizontal plate 801 close to the movable plate 707, and a lever 809 is slidably connected in the sliding groove 810. A lever 809 is fixedly connected to the end of the lever 809 away from the sliding groove 810, and a lever plate 808 is fixedly connected to the lever plate 808. A rotating shaft 806 is fixedly connected to the lever plate 808. A vertical plate 807 is rotatably connected to the outer surface of the rotating shaft 806. The vertical plate 807 is fixedly connected to the upper end surface of the mounting plate 5. When the rotating shaft 806 rotates on the vertical plate 807, the lever plate 808 is set to drive the lever 809 to slide back and forth in the sliding groove 810, and the horizontal plate 801 is driven to reciprocate up and down synchronously.

[0046] In this embodiment, Figure 8 As shown, the end of the rotating shaft 806 away from the dial plate 808 is fixedly connected to the transmission gear 805, and the rack plate 804 is meshedly connected below the transmission gear 805. The rack plate 804 is fixedly connected to the side wall of the movable plate 707. When the movable plate 707 moves horizontally and drives the rack plate 804 to move synchronously, the rotating shaft 806 can rotate on the vertical plate 807 through the meshing connection between the rack plate 804 and the transmission gear 805.

[0047] In the prior art, workers generally vibrate the concrete only after the concrete in the double T-plate mold is injected and flattened, so as to eliminate bubbles and air in the concrete. Compared with the prior art, while the spreading plate 710 automatically spreads the concrete in the mold body 1, it can simultaneously drive the vibrating plate 803 to reciprocate and vibrate the flattened concrete, which can not only eliminate bubbles and gaps in the concrete, but also make the concrete fill the interior of the mold body 1 more evenly, thereby improving the density and firmness of the concrete, and the automation of the vibration process can reduce the risk of manual operation and improve construction safety.

[0048] The working process and principle involved in the overall content of the above embodiment are as follows:

[0049] When the staff needs to use the mold body 1 to produce double T-plates, the mold body 1 is pre-processed first, and then concrete is poured into the pouring funnel 3, and the concrete can flow into the mold body 1 below through the pouring pipe 4 connected to the lower end surface of the pouring funnel 3. At the same time, when the concrete flows into the mold body 1, the staff can drive the pouring funnel 3 to slide horizontally on the mounting frame 2, so that the pouring pipe 4 can pour the concrete into various places inside the mold body 1;

[0050] When concrete flows into the mold body 1, the staff can turn on the driving motor to drive one of the sprockets 702 to rotate under the support frame 701, and drive the other sprocket 702 to rotate at the same time through the chain 703 set between the two sprockets 702, so that the chain 703 can move around the two sprockets 702. With the movement of the chain 703, the linkage column 706 connected to the lower end of the chain 703 can be driven to move synchronously. When the linkage column 706 is driven to slide in the moving groove 708 opened on the upper end surface of the moving plate 707, the sliding plate 709 is driven to slide synchronously in the through groove 6 opened on the mounting plate 5 through the moving plate 707. During the reciprocating sliding process in the through groove 6, the spreading plate 710 connected to the lower end of the slide plate 709 can be driven to move synchronously, so that the spreading plate 710 automatically and evenly pushes the concrete poured from the lower end of the pouring pipe 4 into the mold body 1, which not only ensures the uniform distribution of the concrete in the mold body 1, but also avoids the problems of uneven concrete thickness and uneven surface caused by improper manual operation, thereby improving the overall performance quality and appearance of the double T-plate. Moreover, compared with the existing concrete leveling mechanism, the spreading plate 710 can automatically move synchronously with the pouring pipe 4, thereby improving the smoothness of concrete leveling and improving the safety of workers during the construction process.

[0051] When the spreading plate 710 pushes the concrete to approach the edge of the mold body 1, the fixed blocks 715 on both sides of the spreading plate 710 will preferentially contact the limit blocks 705 connected to the side walls of the partition 704, and will be hindered by the limit blocks 705, which will push the fixed blocks 715 to approach the spreading plate 710. At the same time, the elastic telescopic column 714 connected between the fixed blocks 715 and the spreading plate 710 will be squeezed. In the process of the fixed blocks 715 approaching the spreading plate 710, one end of the push rod 716 will be driven to move horizontally synchronously. When the push rod 716 is pushed, the push rod 716 will push the material. The plate 712 moves horizontally on the side wall of the spreading plate 710 away from the partition 704, pushing the concrete accumulated on one side of the spreading plate 710 to the inside of the mold body 1 in front, thereby avoiding the occurrence of excess concrete spilling out of the mold body 1, which not only ensures that the concrete is fully utilized in the mold body 1, reducing the waste caused by spilling, thereby reducing the construction cost, but also maintains the cleanliness of the construction site, improves the construction environment, avoids the hidden danger of tripping or slipping caused by spilled concrete at the construction site, and further improves the safety of workers during the construction process;

[0052] When the movable plate 707 is moved back and forth horizontally by the linkage column 706, the movable plate 707 can drive the rack plate 804 connected to one side to move horizontally synchronously, and drive the rotating shaft 806 to rotate synchronously on the vertical plate 807 through the meshing connection between the rack plate 804 and the upper transmission gear 805. As the rotating shaft 806 rotates, the rotating shaft 806 can drive the lever 809 to move synchronously around the rotating shaft 806 through the lever plate 808. At the same time, the lever 809 will slide back and forth in the slide groove 810 opened on the side wall of the horizontal plate 801. , and the horizontal plate 801 is moved to drive the sliding column 802 connected to the lower end surface to move up and down on the mounting plate 5. In the process of the sliding column 802 moving up and down, the vibrating plate 803 will be driven to move up and down synchronously, so that the vibrating plate 803 can vibrate the leveled concrete up and down, which can not only eliminate bubbles and gaps in the concrete, but also make the concrete fill the interior of the mold body 1 more evenly, thereby improving the density and firmness of the concrete, and the automation of the vibration process can reduce the risk of manual operation and improve construction safety.

[0053] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
