Description

Technical Field

[0001] This application relates to the field of casting and molding technology, and in particular to an energy-saving casting and molding device and casting method for pile caps. Background Technology

[0002] A pile cap is a component placed on top of a pile to support and connect to the superstructure. Its core function is to protect the pile top and evenly distribute the load of the superstructure. Pile cap construction requires the use of specialized pouring equipment to pour concrete, and construction is completed after the concrete has cured. However, existing pouring equipment has the following problems during the concrete pouring process: First, when the slump (a core indicator of concrete workability and fluidity) is low, the concrete's fluidity decreases significantly, making it highly susceptible to pouring blockages. Traditional hoppers lack anti-blocking structures, leading to concrete sticking at the discharge port, which in turn causes pouring blockages and ultimately interrupts the construction process. Second, during pouring, material may accumulate locally after entering the mold, resulting in trapped air within the mold (which cannot be expelled in time). This can cause honeycomb-like defects on the surface of the molded product, severely impacting the quality of the finished product and causing significant resource waste.

[0003] In view of this, this application proposes an energy-saving casting and molding device and casting method for pile caps. Summary of the Invention

[0004] The purpose of this application is to address the technical problems identified in the background section by proposing an energy-saving casting and molding device and casting method for pile caps.

The side wall of the lower cover is provided with a leveling mechanism, which levels the material inside the mold assembly. The side wall of the lower cover is also provided with a spring mechanism connected to the leveling mechanism. With the cooperation of the spring mechanism, the leveling mechanism triggers an intermittent tapping mechanism to intermittently tap the mold assembly, so that the poured material is properly vented. A valve is installed at the bottom of the mixing tank, and a vibration motor is installed on the side wall of the discharge pipe.

[0006] Preferably, an arc-shaped plate is fixedly connected between two legs on the same side, and a support plate is fixedly connected to the upper ends of the two arc-shaped plates.

A rotating rod is rotatably connected through the support plate. A gear that meshes with the toothed ring is sleeved on the side wall of the rotating rod. It also includes a tracking transmission component, which tracks and limits the gear to ensure that the gear is always engaged with the ring gear.

[0007] Preferably, the tracking transmission component includes several vertical slots formed on the side wall of the rotating rod, and several sliders are fixedly connected to the inner wall of the gear, with the several sliders slidably connected in the several vertical slots respectively; The gear has convex rings rotatably connected to both the upper and lower end faces. The inner wall of the vertical ring plate is fixedly connected to a pair of clamping rings located above and below the gear ring, respectively. The two clamping rings abut against the end faces of the two convex rings that are far apart from each other.

[0008] Preferably, the rebound mechanism includes a fixed ring plate and a limiting ring fixedly sleeved on the lower cover body and the lower end side wall, wherein the limiting ring is used to limit the downward movement of the transmission ring plate; The lower end of the fixed ring plate is rotatably connected to a support ring plate. The support ring plate and the transmission ring plate are connected by several telescopic rods. Several springs are also connected between the support ring plate and the transmission ring plate. The springs and the telescopic rods are staggered.

[0009] Preferably, the intermittent tapping mechanism includes a support collar fixedly sleeved on the lower side wall of one of the legs, and a lifting block is fixedly connected to the side wall of the support collar near the mold assembly; A pair of connecting plates are fixedly connected to the bottom end of the transmission ring plate. The side walls of the two connecting plates are fixedly connected to a lifting ring. When the lifting ring slides to the upper end of the lifting block, it lifts the transmission ring plate. A striking rod is fixedly connected between the two connecting plates. When the lifting ring moves away from the lifting block, the striking rod will move downward and touch the mold assembly. A flat plate is fixedly connected to the lower end of the striking rod.

[0010] Preferably, a servo motor is installed on the upper end of one side of the support plate, and the output shaft of the servo motor is fixedly connected to the rotating rod; The vibratory motor is installed on the upper side of the other side of the support plate, and the vibrating end of the vibratory motor is connected to the side wall of the feed pipe.

[0011] Preferably, a DC pipe is fixedly connected to the bottom end of the feeding pipe, and a pair of shunt pipes are connected to the side wall of the feeding pipe. The output ends of the two shunt pipes and the DC pipe are all located inside the lower cover. The output ends of both shunt tubes and the DC tube extend to the bottom of the lower cover.

[0012] Preferably, a fixing ring is fixedly connected to the upper end of the mixing tank, and a plurality of hanging rings are fixedly connected to the upper end of the fixing ring.

[0013] Preferably, the mold assembly includes a mold base, and a pair of mold frames are connected to the upper end of the mold base, the two mold frames being rotatably connected; A connecting plate is fixedly connected to the bottom outer side wall of both mold frames. The connecting plate is fixed to the mold base by bolts. An arc-shaped convex plate is fixedly connected to the side wall of both mold frames. A positioning ring located at the upper end of the two arc-shaped convex plates is fitted on the side wall of both mold frames. A steel cage is installed in both mold frames.

[0014] On the other hand, this application proposes a method for casting pile caps, applied to the energy-saving casting and molding device described above, comprising the following steps: Open the valve at the bottom of the mixing tank, and the material in the mixing tank will be poured into the mold assembly through the discharge pipe, two branch pipes, and a direct pipe; Start the vibration motor; Start the leveling mechanism to evenly level the material inside the mold assembly; With the cooperation of the springback mechanism, the leveling mechanism triggers the intermittent tapping mechanism to intermittently tap the mold components, so that the poured material can be properly vented.

[0015] Compared with the prior art, this application has the following beneficial technical effects: This application connects the lower cover to the output end of the feeding pipe and sets a leveling mechanism on the side wall of the lower cover. The leveling mechanism can evenly level the material poured into the mold assembly and avoid local accumulation of the poured material. With the cooperation of the rebound mechanism, the leveling mechanism will also drive the tapping rod to vibrate intermittently up and down while leveling the material. When the tapping rod moves downward, it will touch the mold assembly, thereby causing the mold assembly to vibrate intermittently, so that the poured material can be vented and settled, which can improve the quality of the pile cap after casting and reduce the loss. By setting up a tracking transmission component, the gear and the gear ring remain engaged during the up-and-down movement of the transmission ring plate, ensuring the stability of the flat material and thus guaranteeing the effect of each pour, improving the quality of the molded product and the resource utilization rate.

[0018] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0020] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] like Figures 1-8 As shown, this application proposes an energy-saving casting and molding device for pile caps, comprising a mixing tank 2 and a feeding pipe 3 connected to its bottom end. A valve is installed at the bottom end of the mixing tank 2 to control the opening and closing of the feeding pipe. A vibration motor 6 is installed on the outer wall of the feeding pipe 3. During casting, the vibration motor 6 is activated, generating vibration that drives the feeding pipe 3 to vibrate. This effectively prevents material adhesion within the feeding pipe 3, eliminating blockages and significantly reducing equipment maintenance costs and energy waste. In this embodiment, as... Figure 1 As shown, the discharge pipe 3 is composed of an inverted conical discharge section and a circular pipe section connected at the bottom of the mixing tank 2. The diameter of the inverted conical discharge section decreases sequentially along the material flow direction. After the material is discharged from the mixing tank 2, it is guided and converged by the inverted conical discharge section and stably conveyed by the circular pipe section to complete the discharge operation. The vibrating motor 6 can be installed on the outer wall of the inverted conical discharge section or on the outer wall of the circular pipe section. No specific limitation is made here, and users can adjust it flexibly according to actual needs. A fixing ring 15 is fixedly connected to the upper end of the mixing tank 2, and several hanging rings 16 are fixedly connected to the upper end of the fixing ring 15. When offshore hoisting construction is required, the entire device can be lifted by hooking the hanging rings 16 with hoisting equipment and moved to the position to be poured for pouring, which can adapt to more pouring scenarios.

[0024] The control valve at the bottom of mixing tank 2 is a solenoid valve. This solenoid valve is wirelessly connected to the control room, supporting remote control, reducing energy consumption for on-site personnel, and greatly facilitating offshore operations. This technology is existing and will not be elaborated upon here.

[0025] The mixing tank 2 is supported by several support legs 1 to ensure its stability during operation. These support legs 1 can be telescopic rods for flexible adjustment according to the actual pouring height. Figure 2 As shown, the output end of the feed pipe 3 is fixedly connected to a lower cover 7. The lower cover 7 supports and diverts the material poured from the mold assembly 10, expanding the area over which the material falls and preventing it from concentrating in one place, thus reducing the risk of blockage. Specifically, as... Figure 3 As shown, a DC pipe 9 is fixedly connected to the bottom end of the feed pipe 3, and a pair of diversion pipes 8 are connected to the side wall of the feed pipe 3. The output ends of the two diversion pipes 8 and the DC pipe 9 are all located inside the lower cover 7, which supports and fixes the two DC pipes 9. The output ends of the two diversion pipes 8 and the DC pipe 9 extend to the bottom of the lower cover 7 to prevent material from remaining inside the lower cover 7 during discharge, effectively reducing the risk of blockage.

[0026] Specifically, such as Figure 4 As shown, the mold assembly 10 includes a mold base 101, and a pair of mold frames 104 are connected to the upper end of the mold base 101. The two mold frames 104 are rotatably connected, facilitating opening during demolding. A connecting plate 102 is fixedly connected to the outer bottom wall of each of the two mold frames 104. The connecting plate 102 is fixed to the mold base 101 by bolts 103. A positioning post is fixedly connected to the upper edge of the mold base 101. The connecting plate 102 has positioning holes that match the positioning posts. During mold closing, the two positioning posts are inserted into the two positioning holes respectively, completing the circumferential positioning of the two mold frames 104. Both mold frames 104 have arc-shaped protruding plates 107 fixedly connected to the middle of their side walls. Positioning rings 105 are fitted onto the upper ends of the two arc-shaped protruding plates 107 on the side walls of both mold frames 104. The positioning rings 105 position the two mold frames 104 when they are closed. A crisscrossing steel cage 106 is provided inside both mold frames 104. The steel cages 106 are prefabricated, and their intersecting pattern is not specifically limited. It should be noted that the mold components 10 (especially the mold base 101 and mold frames 104) can be circular, square, or other shapes suitable for the actual scenario. Users can flexibly choose according to specific application requirements.

[0027] Specifically, the lower cover 7 has a leveling mechanism 11 on its side wall. This mechanism leveles the material inside the mold assembly 10. The lower cover 7 also has a spring-loaded mechanism 13 connected to the leveling mechanism 11. With the cooperation of the spring-loaded mechanism 13, the leveling mechanism 11 triggers an intermittent tapping mechanism 14 to intermittently tap the mold assembly 10, ensuring the poured material is properly vented. An arc-shaped plate 4 is fixedly connected between the two support legs 1 on the same side. A support plate 5 is fixedly connected to the upper ends of both arc-shaped plates 4, and the support plate 5 is fitted onto the side wall of the discharge pipe 3. Figure 5 As shown, the flattening mechanism 11 includes a transmission ring plate 111 slidably sleeved on the side wall of the lower cover 7. A vertical ring plate 112 is fixedly connected to the upper outer ring of the transmission ring plate 111. A gear ring 113 is fixedly connected to the inner wall of the vertical ring plate 112. A rotating rod 114 is rotatably connected through the support plate 5. A gear 115 that meshes with the gear ring 113 is sleeved on the side wall of the rotating rod 114. A servo motor 116 is installed on the upper side of one side of the support plate 5, and the output shaft of the servo motor 116 is fixedly connected to the rotating rod 114. A vibration motor 6 is installed on the upper side of the other side of the support plate 5, and the vibration end of the vibration motor 6 is connected to the side wall of the feed pipe 3. Figure 6 As shown, the servo motor 116 is started to drive the rotating rod 114 to rotate, which in turn causes the gear 115 to mesh with the gear ring 113 for transmission, driving the vertical ring plate 112 and the transmission ring plate 111 to rotate. Finally, the two connecting plates 117 drive the striking rod 118 and the flat plate 119 to rotate, so as to evenly distribute the material falling from the upper end of the mold assembly 10.

[0028] Furthermore, such as Figure 3 and Figure 7 As shown, the system also includes a tracking transmission component 12, which tracks and limits the gear 115, ensuring that the gear 115 is always engaged with the gear ring 113 and preventing the gear 115 from disengaging from the gear ring 113. The tracking transmission component 12 includes several vertical slots 123 formed on the side wall of the rotating rod 114. Several sliders are fixedly connected to the inner wall of the gear 115, and these sliders are slidably connected within the vertical slots 123. Both the upper and lower end faces of the gear 115 are rotatably connected to convex rings 122. A pair of clamping rings 121, located above and below the gear ring 113 respectively, are fixedly connected to the inner wall of the vertical ring plate 112. The two clamping rings 121 abut against the mutually distant end faces of the two convex rings 122. The two clamping rings 121 do not directly contact the gear 115, reducing wear on the gear 115.

[0029] Among them, such as Figure 8As shown, the rebound mechanism 13 includes a fixed ring plate 135 and a limiting ring 134 fixedly sleeved on the lower cover 7 and its lower side wall. The limiting ring 134 is used to limit the downward movement of the transmission ring plate 111. A support ring plate 132 is rotatably connected to the lower end of the fixed ring plate 135. The support ring plate 132 and the transmission ring plate 111 are connected by several telescopic rods 131. Each telescopic rod 131 includes a connecting cylinder and a connecting rod. The connecting rod slides inside the connecting cylinder, and a limiting ring is provided on the inner wall of one end of the connecting cylinder to prevent the connecting rod from slipping. The connecting rod is fixed to the support ring plate 132, and the connecting cylinder is fixed to the transmission ring plate 111. Several springs 133 are also connected between the support ring plate 132 and the transmission ring plate 111. The springs 133 are staggered from the telescopic rods 131. The intermittent tapping mechanism 14 includes a support collar 145 fixedly sleeved on the lower side wall of one of the support legs 1. A lifting block 142 is fixedly connected to the side wall of the support collar 145 near the mold assembly 10. A pair of connecting plates 117 are fixedly connected to the bottom end of the transmission ring plate 111. A lifting ring 141 is fixedly connected to the side wall of the two connecting plates 117. When the lifting ring 141 slides to the upper end of the lifting block 142, it lifts the transmission ring plate 111. Both sides of the upper end of the lifting block 142 are provided with arc-shaped portions 143. The lower end of the two connecting plates 117 is provided with an arc-shaped portion 144 on the side away from the lifting ring 141. When the connecting plates 117 move to the upper end of the lifting block 142, the friction between the connecting plates 117 and the lifting block 142 is reduced. A striking rod 118 is fixedly connected between the two connecting plates 117. When the lifting ring 141 moves away from the lifting block 142, the striking rod 118 moves downward and touches the mold assembly 10 (under the rebound force of several springs 133). The contact between the striking rod 118 and the mold assembly 10 is equivalent to striking the mold assembly 10, causing the mold assembly 10 to vibrate, the material inside the mold assembly 10 settles, and the gas inside the material is expelled. A flat plate 119 is fixedly connected to the lower end of the striking rod 118. The flat plate 119 evenly levels the material at the upper end of the mold assembly 10.

[0030] The working principle of this embodiment is as follows: First, the raw materials are added into the mixing tank 2. The mixing tank 2 is equipped with a stirring mechanism, which is a prior art structure and will not be described in detail, nor is it shown in the figure. The mold assembly 10 is placed directly below the lower cover 7, and the valve at the bottom of the mixing tank 2 is opened. The uniformly stirred material in the mixing tank 2 falls into the mold assembly 10 through two diversion pipes 8 and a direct current pipe 9. During pouring, the servo motor 116 and the vibration motor 6 are started. The vibration motor 6 drives the discharge pipe 3 to vibrate, thereby preventing material adhesion and allowing the material in the discharge pipe 3 to be smoothly discharged through the two diversion pipes 8 and the direct current pipe 9. The output shaft of the servo motor 116 rotates, causing the rotating rod 114 to rotate. The rotation of the rotating rod 114 causes the gear 115 to mesh with the gear ring 113, which in turn drives the vertical ring plate 112 and the transmission ring plate 111 to rotate. The rotation of the transmission ring plate 111 causes the two connecting plates 117 to move in a circular motion around the mold assembly 10, which in turn causes the striking rod 118 to drive the flat material plate 119 to evenly distribute the material above the mold assembly 10, so as to even out the material poured into the mold assembly 10 and prevent the falling material from accumulating locally.

[0031] When the two connecting plates 117 rotate around the mold assembly 10, they drive the lifting ring 141 to rotate as well. When the lifting ring 141 moves away from the lifting block 142, the rebound force of several springs 133 will cause the transmission ring plate 111 to move downward instantly. This, in turn, drives the striking rod 118 to move downward instantly through the two connecting plates 117, striking the upper end of the mold assembly 10. For every rotation of the transmission ring plate 111, the striking rod 118 will strike the mold assembly 10 once, thus achieving intermittent striking. This allows the material inside the mold assembly 10 to be vented under vibration, ensuring the material settles and improving the quality of the pile cap after molding.

[0032] When the mold assembly 10 needs to be removed after the pouring is completed, the servo motor 116 stops working when the lifting ring 141 is moved above the lifting block 142. At this time, several springs 133 are in a compressed state, and the striking rod 118 and the flat plate 119 maintain a certain distance from the upper end of the mold assembly 10, making it easy to remove the mold assembly 10. After the material inside the mold assembly 10 is formed, first remove the positioning ring 105 upwards, then loosen several bolts 103, and then open the two mold frames 104. The next step is to demold the pile cap formed inside the two mold frames 104.

[0033] A method for casting pile caps, applied to the energy-saving casting and molding device described above, includes the following steps: Open the valve at the bottom of the mixing tank 2, and the material inside will be poured into the mold assembly 10 through the discharge pipe 3 and then through the two branch pipes 8 and the direct pipe 9. Start the vibration motor 6; Start the leveling mechanism 11 to evenly level the material inside the mold assembly 10; With the cooperation of the springback mechanism 13, the leveling mechanism 11 triggers the intermittent tapping mechanism 14 to intermittently tap the mold assembly 10, so that the poured material is properly vented.

[0034] In this embodiment, the specific steps are as follows: First, place the mold assembly 10 directly below the lower cover 7, open the valve at the bottom of the mixing tank 2, and pour the material in the mixing tank 2 into the mold assembly 10 through the discharge pipe 3 and then through the two branch pipes 8 and the direct pipe 9.

[0035] During pouring, the leveling mechanism 11 and the vibration motor 6 can be activated sequentially. The vibration motor 6 vibrates to prevent material blockage in the discharge pipe 3, and the leveling mechanism 11 works to evenly distribute the material in the mold assembly 10, improving material utilization. Specifically, the vibration motor 6 vibrates to drive the discharge pipe 3 to vibrate, thereby preventing material adhesion in the discharge pipe 3 and allowing the material in the discharge pipe 3 to be smoothly discharged into the mold assembly 10 through the two branch pipes 8 and the direct pipe 9. The output shaft of the servo motor 116 rotates to drive the rotating rod 114 to rotate. The rotation of the rotating rod 114 causes the gear 115 to mesh with the gear ring 113, thereby driving the vertical ring plate 112 and the transmission ring plate 111 to rotate. The rotation of the transmission ring plate 111 causes the two connecting plates 117 to move around the mold assembly 10, thereby causing the striking rod 118 to drive the leveling plate 119 to evenly distribute the material above the mold assembly 10, leveling the material poured in the mold assembly 10, preventing local accumulation of falling material, and thus reducing equipment maintenance costs.

[0036] The leveling mechanism 11, in conjunction with the springback mechanism 13 and the intermittent tapping mechanism 14, can intermittently tap the mold assembly 10, causing it to vibrate during casting and promptly expel gas from the material, thus ensuring material settling. Specifically, as the two connecting plates 117 move around the mold assembly 10, they drive the lifting ring 141 to move in a circular motion. When the lifting ring 141 moves away from the lifting block 142, the rebound force of several springs 133 causes the transmission ring plate 111 to move downward instantaneously. This, in turn, drives the tapping rod 118 to move downward instantaneously via the two connecting plates 117. The tapping rod 118 taps the upper end of the mold assembly 10, and the intermittent tapping of the tapping rod 118 causes the material inside the mold assembly 10 to be expelled under vibration, thus ensuring material settling and effectively improving the yield.

[0037] After the pouring is completed, the lifting ring 141 is positioned above the lifting block 142. At this time, several springs 133 are in a compressed state, and the flat plate 119 is positioned above the mold assembly 10, which facilitates the movement of the mold assembly 10 to the forming area, thereby smoothly carrying out the next round of pouring operations and improving work efficiency.
