A concrete pouring device based on high-performance composite materials

Abstract

This invention discloses a concrete pouring device based on high-performance composite materials, belonging to the technical field of concrete pouring devices. It includes a support frame body, a feeding hopper, a trough unit, a wear-resistant liner, an adjusting guide rail, a locking component, an end baffle plate, a support frame, a guide hopper, a plate, guide scrapers, elastic scrapers, a linkage rod, and a traction rod. The feeding hopper is located on the upper part of the support frame body, and the trough unit is inclinedly located on the support frame body and connected to the lower end of the feeding hopper. By setting a traction rod and a linkage rod between the end baffle plate and the plate, the rotational displacement of the end baffle plate can be transmitted to the plate during the process of the end baffle plate turning from the open position to the baffle position, thereby causing the plate to swing synchronously. Therefore, the trough cleaning action does not rely on additional driving components but is completed by the closing action of the baffle plate itself. This allows the residual material in the trough to move downstream while stopping material discharge, reducing the need for manual secondary cleaning after material discharge stops.

Description

Technical Field

[0001] This invention relates to the field of concrete pouring equipment technology, specifically to a concrete pouring equipment based on high-performance composite materials. Background Technology

[0002] High-performance composite concrete typically contains fibers, modified particles, admixtures, or other reinforcing components. During the pouring process, the mixture is prone to problems such as increased flow resistance, local accumulation, fiber agglomeration, and residue adhesion at the bottom of the trench.

[0003] Existing pouring equipment mostly uses a feeding hopper in conjunction with an inclined guide chute for continuous material feeding, which can meet the conveying needs of ordinary concrete. However, when conveying composite concrete, after the end of the guide chute is closed, the residue in the chute is easy to adhere along the bottom and side wall of the chute. When it is reopened later, it is easy to cause uneven discharge, blockage, or local concentrated impact.

[0004] Meanwhile, the scraping structure in conventional guide channels is usually set up independently and requires separate driving or manual cleaning. It cannot be synchronized with the end baffle action. When the end baffle is closed, if the residual material in the channel cannot be pushed to the downstream guide port in time, it will affect the continuity and metering stability during the next pour.

[0005] To address this issue, we propose a concrete pouring device based on high-performance composite materials. Summary of the Invention

[0006] In view of this, and in view of the shortcomings of the prior art, the present invention provides a concrete pouring device based on high-performance composite materials to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a concrete pouring device based on high-performance composite materials, comprising a support frame body, a feeding hopper, a trough unit, a wear-resistant liner, an adjusting guide rail, a locking component, an end baffle plate, a support frame, a guide hopper, a plate, guide scraper teeth, an elastic scraper, a linkage rod, and a traction rod;

[0008] The feed hopper is located on the upper part of the support frame body. The trough unit is inclined on the support frame body and connected to the lower end of the feed hopper. The wear-resistant liner is located inside the trough unit. The adjusting guide rail is set along the length of the trough unit. The locking part cooperates with the adjusting guide rail to lock the adjustment position of the trough unit. The guide hopper is located at the downstream end of the trough unit through the support frame.

[0009] The end baffle is rotatably positioned between the trough unit and the guide hopper. The plate is rotatably positioned above the trough cavity of the trough unit and extends into the trough unit. The guide scraper teeth are connected to the lower edge of the plate and are staggered along the width direction of the trough unit. The elastic scraper is located at the lower edge of the guide scraper teeth. The linkage rod is connected to the plate. The traction rod is connected between the end baffle and the linkage rod.

[0010] When the end baffle is in the open position, the plate is in a guiding posture, and the guiding scraper teeth form a flow-dividing channel between the teeth. When the end baffle changes from the open position to the baffle position, the plate is driven to the cleaning posture by the traction rod and the linkage rod. The guiding scraper teeth form a partitioned scraping area with overlapping width direction. The guiding scraper teeth and the elastic scraper strip form an arc-shaped scraping path towards the guide hopper along the inner surface of the wear-resistant liner.

[0011] Preferably, the bottom of the feed hopper is provided with a guide cone, the lower end of the guide cone faces the inlet end of the tank unit, and the top end of the guide cone is rotatably installed on the side of the feed hopper.

[0012] Preferably, the side of the feed hopper is provided with a side opening push rod, which is fixedly connected to the top of the guide cone.

[0013] Preferably, the wear-resistant liner is fixedly installed on the inner surface of the tank cavity of the tank unit, and the tank unit is provided with support crossbars at intervals above it. Each support crossbar is fixedly installed with a positioning shaft seat on its surface. The plate is rotatably positioned inside the tank unit through the positioning shaft seat at the corresponding position. The support crossbars are horizontally arranged above the tank unit, and the positioning shaft seat is connected to the surface of the support crossbars.

[0014] Preferably, the elastic scraper extends along the width direction of the groove unit and abuts against the inner surface of the wear-resistant liner.

[0015] Preferably, the upper surfaces of the wear-resistant liners on both sides are respectively provided with a single-sided limiting block and a swing shaft seat. The single-sided limiting block is fixedly installed on the upper surface of the wear-resistant liner, and the swing shaft seat is fixedly installed on the upper surface of the wear-resistant liner on the other side. The single-sided limiting block restricts the position of the support crossbar and restricts the plate body from moving axially along the support crossbar. One end of the support crossbar is rotatably supported by the swing shaft seat.

[0016] Preferably, each support crossbar has a hinge seat fixedly installed on one end surface near the single-sided limiting block, and the linkage rod is rotatably installed between two adjacent hinge seats, and the linkage rod drives the plate to rotate through the hinge seats.

[0017] Preferably, a spring pin is fixedly connected to the surface of the end baffle, and an arc-shaped limiting plate is provided at the downstream end of the tank unit. A positioning hole is opened on the arc-shaped limiting plate, and the spring pin is inserted into the positioning hole to fix the position of the end baffle.

[0018] Preferably, a limit spring is fixedly connected to the surface of the traction rod, a baffle limit seat is fixed to the groove unit, and the end of the limit spring away from the traction rod is fixedly connected to the baffle limit seat.

[0019] Preferably, when the end baffle is in the open position, the downstream end of the tank unit is connected to the guide hopper; when the end baffle is in the blocking position, the end baffle blocks the downstream end of the tank unit.

[0020] Compared with the prior art, the present invention provides a concrete pouring device based on high-performance composite materials, which has the following beneficial effects:

[0021] By setting a traction rod and a linkage rod between the end baffle and the plate body, the rotational displacement of the end baffle can be transmitted to the plate body during the process of the end baffle turning from the open position to the baffle position, thereby causing the plate body to swing synchronously. Thus, the cleaning action does not rely on additional driving components, but is completed by the closing action of the baffle itself. It can push the residual material in the trough to move downstream while stopping the discharge, reducing the need for manual secondary cleaning after the material is stopped.

[0022] By setting guide scrapers at intervals and staggered along the width direction of the tank unit at the lower edge of the plate, when the end baffle is in the open position, a flow-dividing gap is formed between the guide scrapers to allow the material to pass through. When the high-performance composite concrete passes through the tank unit, the fibers, reinforcing particles and slurry in the material can be dispersed and guided, and are not easy to concentrate on one side or local area of ​​the tank unit, thereby improving the problems of flow deviation, accumulation and agglomeration of composite concrete during the material guiding process.

[0023] When the end baffle is closed, it drives the plate to rotate, and the guide scraper teeth switch from the guiding state to the scraping state, forming overlapping partitioned scraping areas in the width direction of the tank unit. These partitioned scraping areas can cover the bottom of the tank and the residual material attachment position near the side wall, making it difficult for residual concrete to stay in the gap between individual scraper teeth, and can be pushed to the inlet of the guide hopper in the downstream direction of the tank unit, reducing the risk of material blockage or instantaneous concentrated discharge when the discharge is reopened.

[0024] By setting an elastic scraper at the lower edge of the guide scraper teeth, the elastic scraper can adhere to the inner surface of the wear-resistant liner when the plate rotates to clean the groove. Since the elastic scraper can adapt to the contact with residual material or local unevenness on the surface of the wear-resistant liner, it can improve the scraping effect of adhering slurry and fine aggregate residue, and reduce the rigid friction between the guide scraper teeth and the wear-resistant liner, thus reducing wear during long-term use.

[0025] By setting spring pins, arc-shaped limit plates, and positioning holes, the end baffle plate can be positioned and fixed after rotating to the open or baffle position. At the same time, the traction rod, together with the limit spring and the baffle limit seat, provides certain limit and reset constraints for the linkage action between the end baffle plate and the plate body. This can prevent the end baffle plate from swinging unexpectedly due to material impact or equipment vibration during the pouring process, and keep the discharge, baffle, and trough cleaning actions stable.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Embodiments of the present invention

[0037] Specific reference Figures 1 to 3 This embodiment provides a high-performance composite material concrete pouring device, including a support frame body 11, a feeding hopper 21, a side-opening push rod 22, a guide cone 23, a trough unit 31, a wear-resistant liner 32, an adjusting guide rail 41, a locking component 42, an end baffle plate 51, a support frame 61, a guide hopper 62, a single-sided limiting block 71, a swing shaft seat 72, a support crossbar 731, a positioning shaft seat 732, a plate 733, a flow guide scraper tooth 734, an elastic scraper strip 735, a hinge seat 741, a linkage rod 742, a traction rod 751, a limiting spring 752, and a baffle limiting seat 753.

[0038] The main body 11 of the support frame is formed by connecting vertical support members, horizontal connecting members and oblique reinforcing members. It is used to support the feed hopper 21 and the trough unit 31, and to position the feed hopper 21 above the trough unit 31. The trough unit 31 is inclined along the material flow direction, with its upstream end corresponding to the lower end of the feed hopper 21 and its downstream end facing the guide hopper 62.

[0039] The following description of the installation relationship between the support frame body 11 and the trough unit 31 is provided in the reference section. Figures 1 to 3 The upper part of the support frame body 11 forms an installation area for fixing the feed hopper 21, and the middle part of the support frame body 11 forms a material guiding area for supporting the trough unit 31. The upstream end of the trough unit 31 is close to the bottom of the feed hopper 21, and the downstream end of the trough unit 31 is lower than the upstream end, so that the high-performance composite concrete entering the trough unit 31 can flow in the direction of the feed hopper 62 under its own weight. The bottom of the support frame body 11 is provided with a support part for ground support, so that the device remains stable during the pouring operation.

[0040] For details regarding the feed hopper 21, the side-opening push rod 22, and the guide cone 23, please refer to [link / reference needed]. Figures 1 to 3 The feed hopper 21 is an open-top material-containing structure. The lower end of the feed hopper 21 forms a discharge port, which corresponds vertically to the inlet end of the trough unit 31. The guide cone 23 is located at the bottom of the feed hopper 21, with its lower end facing the inlet end of the trough unit 31. The guide cone 23 is used to guide the material falling from the feed hopper 21 into the trough unit 31, avoiding direct impact of the material on a local area of ​​the trough unit 31.

[0041] The top of the guide cone 23 is rotatably mounted on the side of the feed hopper 21, and the side opening push rod 22 is fixedly connected to the top of the guide cone 23. When the operator pushes or pulls the side opening push rod 22, the side opening push rod 22 drives the guide cone 23 to rotate around its top, thereby adjusting the feeding opening and feeding direction of the bottom of the feed hopper 21 to the trough unit 31.

[0042] For details regarding the following description of the tank unit 31 and the wear-resistant liner 32, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 7 The trough unit 31 is an open guide trough structure. The trough unit 31 includes a bottom guide surface and lateral baffles on both sides of the bottom guide surface. The bottom guide surface and the lateral baffles together define a trough cavity for the flow of high-performance composite concrete. The wear-resistant liner 32 is fixedly installed on the inner surface of the trough cavity of the trough unit 31. The wear-resistant liner 32 covers at least the bottom guide surface of the trough unit 31 and the lateral baffles near the material flow area. The wear-resistant liner 32 is fitted to the inner wall of the trough unit 31 and fixed by a fastening connection, so that the wear-resistant liner 32 is not easy to lift or shift under the action of material flushing and scraping.

[0043] For details regarding the following description of the adjusting guide rail 41 and the locking element 42, please refer to [link / reference]. Figure 1 and Figure 2 The adjusting guide rail 41 is set along the length of the trough unit 31. The adjusting guide rail 41 cooperates with the support frame body 11 to form the position adjustment path of the trough unit 31. The locking member 42 cooperates with the adjusting guide rail 41. When the trough unit 31 moves relative to the support frame body 11 to the predetermined material guiding position, the locking member 42 locks the position between the trough unit 31 and the adjusting guide rail 41. Through the cooperation of the adjusting guide rail 41 and the locking member 42, the trough unit 31 can adjust the extension position according to the pouring height and material guiding distance at the construction site, and maintain a stable inclined material guiding state after adjustment.

[0044] For details regarding the following description of the support frame 61 and the guide hopper 62, please refer to [link / reference]. Figures 2 to 4 The support frame 61 is located at the downstream end of the tank unit 31. The support frame 61 is used to support the guide hopper 62 and maintain the relative position between the guide hopper 62 and the downstream end of the tank unit 31. The guide hopper 62 is located on the support frame 61. The upper opening of the guide hopper 62 corresponds to the downstream end of the tank unit 31. The lower part of the guide hopper 62 forms a discharge channel. After the high-performance composite concrete discharged from the downstream end of the tank unit 31 enters the guide hopper 62, it can be concentrated and guided to the pouring position through the guide hopper 62 to reduce the overflow when discharging downstream.

[0045] For details regarding the end baffle 51, please refer to the following description. Figures 2 to 5 The end baffle plate 51 is rotatably disposed between the trough unit 31 and the guide hopper 62. The plate surface of the end baffle plate 51 corresponds to the downstream end of the trough unit 31. When the end baffle plate 51 is in the open position, the downstream end of the trough unit 31 is connected to the guide hopper 62.

[0046] When the end baffle 51 is in the baffle position, the end baffle 51 blocks the downstream end of the trough unit 31. The end baffle 51 switches between the open position and the baffle position by rotating, so that the device can switch between continuous discharge and paused discharge.

[0047] The following description of the positioning structure of the end baffle 51 is provided in the reference section. Figure 4 and Figure 5 A spring pin 521 is fixedly connected to the surface of the end baffle plate 51. An arc-shaped limiting plate 522 is located at the downstream end of the tank unit 31. The extension direction of the arc-shaped limiting plate 522 corresponds to the rotation trajectory of the end baffle plate 51. A positioning hole 523 is provided on the arc-shaped limiting plate 522. The positioning hole 523 is arranged along the rotation path of the end baffle plate 51. When the end baffle plate 51 rotates to the open position, the spring pin 521 is inserted into the corresponding positioning hole 523, thereby fixing the end baffle plate 51 in the corresponding position and preventing the end baffle plate 51 from swinging unexpectedly due to material impact or device vibration.

[0048] For details regarding the following descriptions of the support crossbar 731, the positioning shaft seat 732, and the plate 733, please refer to [the provided text]. Figures 6 to 8 Multiple support crossbars 731 are spaced apart above the trough unit 31 along the material flow direction. The support crossbars 731 are horizontally straddling the trough unit 31. A positioning shaft seat 732 is fixedly installed on the surface of each support crossbar 731. The upper end of the plate 733 is rotatably connected to the corresponding position of the support crossbar 731 through the positioning shaft seat 732, so that the plate 733 can swing relative to the trough unit 31. The lower part of the plate 733 extends into the trough cavity of the trough unit 31. The plate 733 is inclined relative to the trough unit 31, so that the lower edge of the plate 733 can approach the inner surface of the wear-resistant liner 32, while the plate 733 does not completely block the material channel in the trough unit 31.

[0049] For details regarding the following description of the guide scraper teeth 734 and the elastic scraper strip 735, please refer to [link / reference]. Figures 6 to 8 The guide scraper teeth 734 are connected to the lower edge of the plate 733 and are arranged at intervals along the width direction of the trough unit 31. A tooth gap is formed between adjacent guide scraper teeth 734 to allow high-performance composite concrete to pass through. The guide scraper teeth 734 on the multiple plates 733 are staggered in the width direction so that the material can be dispersed and guided when passing through the guide scraper teeth 734. The side of the guide scraper teeth 734 near the feed end of the trough unit 31 is set as a smooth plane, which faces the material flow direction from the feed hopper 21 into the trough unit 31.

[0050] The elastic scraper 735 is located at the lower edge of the guide scraper tooth 734. The elastic scraper 735 extends along the width direction of the tank unit 31 and abuts or is close to the inner surface of the wear-resistant liner 32. When the plate 733 swings, the elastic scraper 735 can adapt to the local undulations of the inner surface of the wear-resistant liner 32, thereby flexibly scraping the residue adhering to the wear-resistant liner 32.

[0051] The following explanation regarding the fit between the smooth surface of the guide scraper tooth 734 and the inclined posture of the plate 733 is provided in the following reference. Figures 6 to 8 Since the plate 733 is inclined relative to the tank unit 31, when the guide scraper 734 extends into the tank cavity of the tank unit 31 along with the plate 733, the side of the guide scraper 734 near the feed end of the tank unit 31 first contacts the material sliding down the tank unit 31. The smooth plane is used to receive the material and guide the material to continue sliding downstream, reducing the fiber, reinforcing particles or slurry from getting stuck in front of the guide scraper 734. After the material moves along the smooth plane, it enters the downstream guiding area through the gap between adjacent guide scrapers 734, thus forming a diversion and guiding effect.

[0052] For details regarding the single-sided limiting block 71 and the swing shaft seat 72, please refer to the following description. Figure 6 and Figure 7 A single-sided limiting block 71 is fixedly installed on the upper surface of one side of the wear-resistant liner 32, and a swing shaft seat 72 is fixedly installed on the upper surface of the other side of the wear-resistant liner 32. One end of the support crossbar 731 is axially limited by the single-sided limiting block 71, and the other end of the support crossbar 731 is rotatably supported by the swing shaft seat 72. The single-sided limiting block 71 restricts the support crossbar 731 from moving along its axial direction, and the swing shaft seat 72 provides rotational support for the support crossbar 731, so that the support crossbar 731 can drive the positioning shaft seat 732 and the plate 733 to swing synchronously when subjected to force.

[0053] For details regarding the following description of the hinge seat 741 and the linkage rod 742, please refer to [link / reference]. Figure 6 and Figure 7 Each support crossbar 731 has a hinge seat 741 fixedly installed on one end surface near the single-sided limiting block 71. The linkage rod 742 is rotatably installed between two adjacent hinge seats 741. The linkage rod 742 is arranged along the length direction of the groove unit 31 and connects multiple support crossbars 731 into a synchronous swing structure. When one of the support crossbars 731 rotates under the action of external force, the hinge seat 741 drives the linkage rod 742 to move. The linkage rod 742 then drives other support crossbars 731 to rotate through adjacent hinge seats 741, so that multiple plates 733 can swing in the same direction of motion.

[0054] For details regarding the following descriptions of the traction rod 751, the limit spring 752, and the baffle limit seat 753, please refer to [link / reference needed]. Figure 4 , Figure 6 and Figure 7 The traction rod 751 is connected between the end baffle plate 51 and the linkage rod 742. One end of the traction rod 751 rotates with the end baffle plate 51, and the other end of the traction rod 751 acts on the linkage rod 742, so that the opening and closing action of the end baffle plate 51 can be converted into the swing displacement of the linkage rod 742. The limiting spring 752 is connected to the traction rod 751, and the baffle limiting seat 753 is fixed to the tank unit 31. The end of the limiting spring 752 away from the traction rod 751 is connected to the baffle limiting seat 753.

[0055] The limiting spring 752 is used to provide elastic constraint on the traction rod 751, so that the traction rod 751 maintains controlled movement during the opening and closing of the end baffle 51, and assists the end baffle 51 and the plate 733 in resetting or maintaining the corresponding posture.

[0056] The overall working process and principle of the above embodiments are as follows:

[0057] During pouring, the end baffle plate 51 is in the open position, the downstream end of the trough unit 31 is connected to the guide hopper 62, the plate 733 is in the guiding posture, and the guide scraper teeth 734 form a tooth-to-tooth flow channel in the trough unit 31. After the high-performance composite concrete enters the trough unit 31 from the feed hopper 21, it flows downstream along the wear-resistant liner 32. The smooth plane of the guide scraper teeth 734 near the feed end of the trough unit 31 guides the material to meet it, so that the material is not easy to stagnate in front of the guide scraper teeth 734.

[0058] Meanwhile, the gap between adjacent guide scraper teeth 734 diverts the material, making the material distribution more uniform in the width direction of the tank unit 31.

[0059] When it is necessary to stop the discharge, first release the lock between the spring pin 521 and the corresponding positioning hole 523, and then push the end baffle 51 from the open position to the baffle position. During the rotation of the end baffle 51, the traction rod 751 moves, the traction rod 751 drives the linkage rod 742 to move, the linkage rod 742 drives the support crossbar 731 to rotate through the hinge seat 741, and the support crossbar 731 drives the plate body 733 from the flow guiding posture to the cleaning posture through the positioning shaft seat 732.

[0060] At this time, the guide scraper teeth 734 form overlapping partitioned scraping areas in the width direction of the tank unit 31. The guide scraper teeth 734 and the elastic scraper strip 735 form an arc-shaped scraping path along the inner surface of the wear-resistant liner 32 toward the guide hopper 62, pushing the high-performance composite concrete remaining on the inner surface of the tank unit 31 to the inlet of the guide hopper 62. After the end baffle plate 51 rotates to the baffle position, the spring pin 521 is inserted into the corresponding positioning hole 523, so that the end baffle plate 51 remains in the baffle state.

[0061] When the end baffle 51 rotates back from the baffle position to the open position, the lock between the spring pin 521 and the corresponding positioning hole 523 is released. The end baffle 51 rotates in the reverse direction, causing the traction rod 751 to move in the reverse direction. The traction rod 751 drives the linkage rod 742 to move in the reverse direction. The linkage rod 742 drives the support crossbar 731 and the plate 733 to reset via the hinge seat 741, so that the guide scraper tooth 734 re-enters the guide posture. After the end baffle 51 rotates to the open position, the spring pin 521 is inserted into the corresponding positioning hole 523. The downstream end of the trough unit 31 remains connected to the guide hopper 62, and the high-performance composite concrete can continue to enter the guide hopper 62 from the trough unit 31 to complete the pouring.
