Description

Technical Field

[0001] This invention relates to the field of basalt fiber reinforced concrete pipe preparation technology, specifically to a basalt fiber reinforced concrete pipe preparation and demolding equipment. Background Technology

[0002] Basalt fiber reinforced concrete pipe is a type of concrete pipe reinforced with basalt fiber, exhibiting excellent compressive strength, bending strength, and corrosion resistance. Compared to traditional concrete pipes, basalt fiber reinforced concrete pipe is lighter, stronger, and more durable, and is widely used in municipal, transportation, and drainage fields, improving the service life and reliability of pipe materials. The manufacturing process of basalt fiber reinforced concrete pipe requires the use of molds to cast and shape the pipe.

[0004] However, the above equipment still has the following problems when in use: during the process of pouring concrete into the outer cylinder, the concrete cannot be poured into the outer cylinder in a dense manner, resulting in uneven distribution of concrete in the mold, especially in the corners or edges of the outer cylinder, and even voids or unsaturated areas may appear, affecting the strength and quality of the final product. Summary of the Invention

[0005] The purpose of this invention is to provide a basalt fiber reinforced concrete pipe preparation and demolding device to solve the problems mentioned in the background art.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A basalt fiber reinforced concrete pipe preparation and demolding device includes: The mobile cart has a U-shaped frame. The chassis is located below the frame of the mobile trolley; The outer mold mechanism is located on the inner side wall of the frame and is snapped into the top of the chassis; The inner mold mechanism is mounted on the frame and snapped into the top of the chassis. The inner mold mechanism is located inside the outer mold mechanism, and there is a mold cavity between the inner mold mechanism and the outer mold mechanism. A compaction mechanism is installed on the inner mold mechanism and is used to compact the material inside the mold cavity. And a pressing mechanism, which is set on the inner mold mechanism, with its pressing end extending into the upper part of the mold cavity.

The tight-fitting mechanism is arranged on the inner mold column.

[0008] Furthermore, the aforementioned outer mold mechanism includes a lifting assembly vertically mounted on the inner side wall of the vehicle frame, and an outer mold cylinder mounted on the movable end of the lifting assembly and engaged with the top of the chassis. The outer mold cylinder is located outside the inner mold column, and a mold cavity is formed between the outer mold cylinder and the inner mold column.

[0009] Furthermore, the outer wall of the aforementioned inner mold column is provided with a number of vertical sliding grooves spaced apart, and the top of the inner mold column is provided with a number of radial sliding grooves spaced apart, with the radial sliding grooves corresponding to and connected to the vertical sliding grooves one by one; The tight mechanism includes a wave-shaped annular disk rotatably disposed on the outer side of the bottom of the push column and located at the top of the inner mold column, an elastic telescopic plate slidably disposed in the vertical slide groove, and a sliding column disposed at the top of the telescopic end of the elastic telescopic plate. The bottom outer edge of the wave-shaped annular disk is provided with a wave reciprocating annular groove. The top of the sliding column passes through the corresponding radial slide groove and slides in cooperation with the wave reciprocating annular groove. The outer wall of the push column is provided with a limiting component for restricting the rotation of the wave-shaped annular disk.

[0010] Furthermore, the aforementioned limiting component includes a ring disposed on the top of the wave-shaped annular disk and located on the outer side of the push post, and an elastic telescopic lever disposed on the outer wall of the push post and corresponding to the inner side of the ring. The inner side wall of the ring is uniformly provided with a plurality of triangular helical teeth along the circumference, and the telescopic end of the elastic telescopic lever is provided with an inclined surface that matches the triangular helical teeth.

[0011] Furthermore, the aforementioned lifting assembly includes a circular frame vertically mounted on the inner wall of the frame, screws rotatably mounted on the inner walls of both ends of the circular frame, a drive motor mounted on the top of the circular frame and connected to the screws, and a movable plate slidably mounted inside the circular frame and threadedly connected to the screws, the end of the movable plate being connected to the side wall of the outer mold cylinder.

[0012] Furthermore, the aforementioned top pressing mechanism includes a second push rod respectively disposed on the top two sides of the horizontal plate, an annular top cover located below the horizontal plate and outside the inner mold column, and an annular pressure plate disposed at the bottom of the annular top cover and outside the inner mold column. The telescopic end of the second push rod passes through the horizontal plate and is connected to the top of the annular top cover. The size of the annular pressure plate matches that of the mold cavity.

[0013] Furthermore, a spring is provided between the top of the aforementioned annular top cover and the bottom of the horizontal plate.

[0014] Furthermore, the aforementioned frame is equipped with a positioning mechanism corresponding to the inner mold mechanism; The positioning mechanism includes two L-shaped slide rods that are symmetrically slidably arranged on both sides of the bottom of the frame, two arc-shaped clamping plates that are respectively arranged at the bottom of the two L-shaped slide rods and are corresponding to each other, and a hinge rod that is hinged between the arc-shaped clamping plates and the side wall of the frame. A torsion spring is provided at the hinge position of the hinge rod and the frame. The two arc-shaped clamping plates are located on both sides of the chassis and are centered and clamped.

[0015] Furthermore, the inner side of the arc-shaped clamp is provided with an arc-shaped locking block, and the outer circumferential wall of the chassis is provided with a positioning groove that matches the arc-shaped locking block.

[0016] The present invention has the following beneficial effects: (1) The basalt fiber concrete pipe preparation and demolding equipment of the present invention, through the setting of the inner mold mechanism and the outer mold mechanism, the driving component on the inner mold mechanism drives the rotating rod to drive the inner mold column to rotate. The rotation of the inner mold column can promote the uniform flow of basalt fiber concrete between the outer mold mechanism and the inner mold mechanism, and reduce the dead corners or uneven pouring phenomena that occur during the concrete pouring process. By setting the compaction mechanism, the basalt fiber concrete in the mold cavity can be more tightly distributed, thereby reducing pores and air bubbles, improving the density of basalt fiber concrete, and thus helping to improve the compressive strength and durability of basalt fiber concrete pipe. The top pressure mechanism is used to compact the basalt fiber concrete at the top of the mold cavity. And when the inner mold mechanism and the outer mold mechanism are reset, the demolding of the basalt fiber concrete in the mold cavity can be realized.

[0017] (2) The basalt fiber concrete pipe preparation and demolding equipment of the present invention, through the cooperation of the wave annular disk, the elastic telescopic plate, the sliding column and the limiting component, when the driving component rotates forward, it drives the inner mold column to rotate through the rotating rod. The rotation of the inner mold column drives the elastic telescopic plate to rotate at the same time, and then drives the wave annular disk to rotate forward through the sliding column. Under the action of the limiting component, the forward rotation of the wave annular disk is restricted. At this time, the sliding column can slide along the wave reciprocating annular groove. Under the action of the vertical sliding groove and the radial sliding groove, the telescopic end of the elastic telescopic plate is finally repeatedly extended out of the vertical sliding groove. When the telescopic end of the elastic telescopic plate extends out, it will apply a certain pressure to the basalt concrete in the mold cavity. The force allows the basalt fiber concrete particles to be arranged more tightly, thereby reducing pores and air bubbles and improving the density of the basalt fiber concrete. When the driving component reverses, it drives the inner mold column to rotate through the rotating rod, and then drives the wave annular disk to reverse through the sliding column. At this time, the limiting component does not limit the wave annular disk, so that the telescopic end of the elastic telescopic plate does not extend out of the vertical sliding groove. At the same time, under the action of the first push rod, the inner mold column is driven to reset, so that when the inner mold column moves upward, it also rotates with the basalt fiber concrete tube to demold, thereby avoiding the basalt fiber concrete from adhering to the inner mold column during demolding, reducing demolding resistance and making the demolding process smoother.

[0018] (3) The basalt fiber concrete pipe preparation and demolding equipment of the present invention, through the cooperation of L-shaped sliding rod, arc-shaped clamping plate and hinge rod, drives the arc-shaped clamping plate to move towards the center of the equipment through the hinge rod, so that the two arc-shaped clamping plates clamp the chassis in the center, thereby ensuring that the outer mold cylinder and inner mold column can be accurately engaged on the top of the chassis, avoiding the situation of mold misalignment.

[0021] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0022] Please see Figure 1-4 An embodiment of the present invention provides a basalt fiber reinforced concrete pipe preparation and demolding device, comprising: The mobile trolley 1 has a U-shaped frame 11. Chassis 2 is located below the frame 11 of the mobile trolley 1, and is situated at the center of the bottom of the mobile trolley 1. The outer mold mechanism 3 is located on the inner side wall of the frame 11 and is engaged with the top of the chassis 2; The inner mold mechanism 4 is mounted on the frame 11 and is snapped into the top of the chassis 2. There is a mold cavity 5 between the inner mold mechanism 4 and the outer mold mechanism 3. The mold cavity 5 facilitates the pouring of basalt fiber concrete, thereby preparing basalt fiber concrete pipes. It should be noted that when both the outer mold mechanism 3 and the inner mold mechanism 4 are engaged on the top of the chassis 2, the inner mold column 44 of the inner mold mechanism 4 is located inside the outer mold cylinder 32 of the outer mold mechanism 3; the outer radial side of the chassis 2 is provided with an annular groove 1 that engages with the outer mold cylinder 32 of the outer mold mechanism 3, and the inner radial side of the chassis 2 is provided with an annular groove 2 that engages with the inner mold column 44 of the inner mold mechanism 4. The compaction mechanism 6 is set on the inner mold mechanism 4 and is used to compact the material in the mold cavity 5, thereby reducing pores and air bubbles and improving the density of the basalt fiber concrete in the mold cavity 5. And a top-pressing mechanism 7, which is set on the inner mold mechanism 4, with its pressing end extending into the upper part of the mold cavity 5; the top-pressing mechanism 7 is used to compact the basalt fiber concrete at the top of the mold cavity 5.

[0023] It is worth noting that the top pressing mechanism 7 does not extend into the position of the tightness mechanism 6. Therefore, when the top pressing mechanism 7 presses the basalt fiber concrete at the top of the mold cavity 5, it will not interfere with the tightness mechanism 6.

[0024] Please see Figure 3-6 Specifically, the inner mold mechanism 4 includes first push rods 41 symmetrically arranged on both sides of the top of the frame 11, a horizontal plate 42 disposed between the top of the telescopic ends of the two first push rods 41, a push column 43 vertically disposed at the bottom of the horizontal plate 42, an inner mold column 44 rotatably disposed at the bottom of the push column 43 and engaged with the top of the chassis 2, a rotating rod 45 rotatably passing through the push column 43 and connected to the top of the inner mold column 44, and a driving component 46 disposed at the top of the horizontal plate 42 and engaged with the rotating rod 45. A tightening mechanism 6 is disposed on the inner mold column 44. It should be noted that the push column 43 has a shaft hole matching the rotating rod 45. The driving component 46 is a servo motor and is fixed to the top center of the horizontal plate 42 by screws. The center of the horizontal plate 42 has a through hole, and the top end of the rotating rod 45 passes through the through hole and is engaged with the output shaft of the servo motor.

[0025] The outer mold mechanism 3 includes a lifting assembly 31 vertically disposed on the inner side wall of the frame 11, and an outer mold cylinder 32 disposed on the moving end of the lifting assembly 31 and engaged with the top of the chassis 2; and the outer mold cylinder 32 is located outside the inner mold column 44, the outer diameter of the inner mold column 44 is smaller than the inner diameter of the outer mold cylinder 32, and a mold cavity 5 is formed between the outer mold cylinder 32 and the inner mold column 44; The lifting assembly 31 includes a U-shaped frame 311 vertically mounted on the inner wall of the frame 11; screws 312 rotatably mounted on the inner walls at both ends of the U-shaped frame 311, with the screws 312 engaging with the inner walls at both ends of the U-shaped frame 311 via shaft holes; a drive motor 313 mounted on the top of the U-shaped frame 311 and connected to the screws 312, the drive motor 313 being a servo motor and fixed to the top of the U-shaped frame 311 by screws; the top end of the screws 312 passing through the shaft hole at the top of the U-shaped frame 311 and engaging with the output shaft of the drive motor 313; and a movable plate 314 slidably mounted inside the U-shaped frame 311 and threadedly connected to the screws 312, the end of the movable plate 314 being connected to the side wall of the outer mold cylinder 32. With this configuration, the drive motor 313 drives the screws 312 to rotate in both directions, thereby raising and lowering the movable plate 314, and ultimately raising and lowering the outer mold cylinder 32.

[0026] It should be noted that the first push rod 41 in this embodiment is an electric push rod, and the two first push rods 41 are symmetrically distributed about the retractable frame 311; the movable plate 314 includes a connecting support plate and a sliding block fixedly connected to the connecting support plate. The sliding block has a rectangular structure, slides with the retractable frame 311, and has a threaded hole that is threaded with the screw 312. The connecting support plate is located on the side facing the inner mold mechanism 4.

[0027] It is worth noting that when the outer mold cylinder 32 is located above the chassis 2 and the sliding block on the moving plate 314 is located on the top inner wall of the return frame 311, this is the initial state of the outer mold mechanism 3; when the telescopic end of the first push rod 41 is in the extended state, the inner mold column 44 is located above the chassis 2, and the outer mold cylinder 32 is located outside the inner mold column 44, this is the initial state of the inner mold mechanism 4. The drive motor 313 drives the screw 312 to rotate, which in turn drives the outer mold cylinder 32 to descend through the moving plate 314 until it engages with the top of the chassis 2. The first push rod 41 is used to drive the horizontal plate 42, the push column 43 and the inner mold column 44 to rise and fall. When the telescopic end of the first push rod 41 descends, it drives the inner mold column 44 to descend and extend into the outer mold cylinder 32 until it engages with the top of the chassis 2. The start drive component 46 drives the rotating rod 45 to rotate. The rotating rod 45 drives the inner mold column 44 to rotate. The rotation of the inner mold column 44 can promote the uniform flow of basalt fiber concrete in the mold cavity 5 and reduce the dead corners or uneven pouring phenomena that occur during the concrete pouring process.

[0028] Please see Figure 6-9 The outer wall of the inner mold column 44 is provided with a number of vertical sliding grooves 47 at intervals, and the top of the inner mold column 44 is provided with a number of radial sliding grooves 48 at intervals. The radial sliding grooves 48 correspond to and are connected to the vertical sliding grooves 47 one by one. The vertical sliding grooves 47 are evenly distributed along the outer periphery of the inner mold column 44, and the radial sliding grooves 48 are evenly distributed along the top circumference of the inner mold column 44. The tight mechanism 6 includes a wave-shaped annular disk 61 rotatably disposed on the outer bottom of the push post 43 and located on the top of the inner mold post 44. The wave-shaped annular disk 61 and the push post 43 are rotated through a shaft hole; an elastic telescopic plate 62 slidably disposed in the vertical slide groove 47, with the telescopic end of the elastic telescopic plate 62 located on the side facing the outer mold cylinder 32; and a sliding post 63 disposed on the top of the telescopic end of the elastic telescopic plate 62. The outer bottom edge of the wave-shaped annular disk 61 is provided with a wave reciprocating annular groove 611. The top of the sliding post 63 passes through the corresponding radial slide groove 48 and slides in cooperation with the wave reciprocating annular groove 611. The outer wall of the push post 43 is provided with a limiting component for restricting the rotation of the wave-shaped annular disk 61.

[0029] It should be noted that the elastic telescopic plate 62 includes a fixed part, a telescopic tube sleeved outside the fixed part, and a return spring connected between the fixed part and the inner wall of the telescopic tube. The telescopic tube serves as the telescopic end of the elastic telescopic plate 62. The inner diameter of the vertical sliding groove 47 matches the size of the telescopic tube. When the return spring is in its natural state, the telescopic tube is located inside the vertical sliding groove 47, and the end face of the telescopic tube away from the fixed part is flush with the outer wall of the inner mold column 44.

[0030] Specifically, the limiting component includes a ring 64 disposed on the top of the wave-shaped annular disk 61 and located on the outer side of the push post 43, and an elastic telescopic locking rod 65 disposed on the outer wall of the push post 43 and corresponding to the inner side of the ring 64. The inner side wall of the ring 64 is evenly provided with a plurality of triangular helical teeth 641 along the circumference. The telescopic end of the elastic telescopic locking rod 65 is provided with an inclined surface 651 that matches the triangular helical teeth 641. The inclined surface 651 is located on the movement path of the triangular helical teeth 641.

[0031] It should be noted that the elastic telescopic lever 65 in this embodiment includes a fixed lever, a telescopic lever sleeved outside the fixed lever, and a second return spring connected between the inner wall of the telescopic lever and the end of the fixed lever. The telescopic lever serves as the telescopic end of the elastic telescopic lever 65. When the second return spring is in its natural state, the elastic telescopic lever 65 engages with the triangular helical tooth 641.

[0032] When the drive component 46 rotates forward, it drives the inner mold column 44 to rotate via the rotating rod 45. The rotation of the inner mold column 44 simultaneously drives the elastic telescopic plate 62 to rotate, which in turn drives the wave annular disk 61 to rotate forward via the sliding column 63. At this time, the telescopic end of the elastic telescopic clamp 65 contacts the triangular helical tooth 641. Under the action of the straight edge of the elastic telescopic clamp 65 and the straight edge of the triangular helical tooth 641, the rotation of the wave annular disk 61 is restricted. At this time, the sliding column 63 can slide along the wave reciprocating annular groove 611. Under the action of the vertical sliding groove 47 and the radial sliding groove 48, the telescopic end of the elastic telescopic plate 62 is eventually repeatedly extended out of the vertical sliding groove 47. When the telescopic end of the elastic telescopic plate 62 extends, it will apply a certain pressure to the basalt concrete in the mold cavity 5, which can make the concrete particles more compactly arranged, thereby reducing pores and air bubbles and improving the density of the concrete.

[0033] When the drive component 46 reverses, it drives the inner mold column 44 to rotate in the opposite direction through the rotating rod 45, and then drives the wave ring disk 61 to reverse through the sliding column 63. At this time, the telescopic end of the elastic telescopic clamp 65 contacts the triangular helical tooth 641. Under the action of the inclined surface 651 and the inclined side of the triangular helical tooth 641, the wave ring disk 61 is not limited and rotates under the drive of the sliding column 63.

[0034] Please see Figure 5The top pressing mechanism 7 includes a second push rod 71 respectively disposed on the top two sides of the horizontal plate 42, the second push rod 71 being an electric push rod; an annular top cover 72 located below the horizontal plate 42 and outside the inner mold column 44; and an annular pressure plate 73 disposed at the bottom of the annular top cover 72 and outside the inner mold column 44. The telescopic end of the second push rod 71 passes through the horizontal plate 42 and is connected to the top of the annular top cover 72. A connecting hole matching the telescopic end of the second push rod 71 is provided on the horizontal plate 42. The size of the annular pressure plate 73 matches the size of the mold cavity 5. The shape and size of the annular top cover 72 are consistent with the shape and size of the annular pressure plate 73.

[0035] To achieve shock absorption and cushioning, a spring 74 is provided between the top of the annular top cover 72 and the bottom of the horizontal plate 42.

[0036] Please see Figure 10 The frame 11 is provided with a positioning mechanism 8 corresponding to the inner mold mechanism 4. The positioning mechanism 8 is used to clamp and center the chassis 2. Specifically, the positioning mechanism 8 includes two L-shaped slide rods 81 symmetrically slidably disposed on both sides of the bottom of the frame 11, with each L-shaped slide rod 81 corresponding to one of the two first push rods 41. The bottom of the frame 11 is provided with a sliding groove matching the lateral portion of the L-shaped slide rods 81. Two arc-shaped clamping plates 82 are respectively disposed at the bottom of the two L-shaped slide rods 81 and corresponding to each other, with the arc-shaped clamping plates 82 connected to the bottom of the vertical portion of the L-shaped slide rods 81. A hinge rod 83 is hinged between the arc-shaped clamping plates 82 and the side wall of the frame 11. A torsion spring is provided at the hinge position between the hinge rod 83 and the frame 11. The two arc-shaped clamping plates 82 are located on both sides of the chassis 2 and are centered and clamped thereon. This arrangement ensures that the outer mold cylinder 32 and the inner mold column 44 can accurately engage on the top of the chassis 2, thereby making the fit between the outer mold cylinder 32 and the inner mold column 44 more precise and avoiding mold misalignment.

[0037] It is worth noting that the hinge rod 83 adopts an elastic telescopic tube. One end of the elastic telescopic tube is hinged to the frame 11, and the other end is hinged to the arc-shaped clamp 82. When the elastic telescopic tube is in its natural extended state, the two arc-shaped clamps 82 are close to each other. When it is necessary to clamp and center the chassis 2, the telescopic part of the elastic telescopic tube can retract and adapt to the position after clamping the chassis 2. At the same time, when the elastic telescopic tube retracts, it will generate a lateral pressure on the outside of the chassis 2, thus making the clamping more secure. The L-shaped slide rod 81 is used to ensure the position of the arc-shaped clamp 82.

[0038] The inner side of the arc-shaped clamping plate 82 is provided with an arc-shaped locking block (not shown in the figure), and the outer circumferential wall of the chassis 2 is provided with a positioning groove that matches the arc-shaped locking block.

[0039] The working process of the basalt fiber reinforced concrete pipe preparation and demolding equipment of the present invention is as follows: (1) Place the chassis 2 under the frame 11 and clamp the chassis 2 in the center by the positioning mechanism 8 so that it corresponds to the bottom of the outer mold mechanism 3 and the inner mold mechanism 4; (2) Start the drive motor 313. The drive motor 313 drives the screw 312 to rotate, and then drives the outer mold cylinder 32 to move downward through the moving plate 314 until it is engaged with the top of the chassis 2. Further start the first push rod 41 and finally drive the inner mold column 44 to descend until it is engaged with the top of the chassis 2. At this time, the inner mold column 44 is located inside the outer mold cylinder 32 and forms a mold cavity 5. (3) The staff pours basalt fiber concrete into the mold cavity 5, starts the drive component 46 to rotate in the forward direction, and then drives the inner mold column 44 to rotate through the rotating rod 45. The rotation of the inner mold column 44 can promote the uniform flow of basalt fiber concrete between the outer mold cylinder 32 and the inner mold column 44, and reduce the dead corners or uneven pouring phenomena that occur during the pouring of basalt fiber concrete. (4) At the same time, the inner mold column 44 will drive the elastic telescopic plate 62 to rotate, and the sliding column 63 will push the wave ring disk 61 to rotate in the forward direction. At this time, under the action of the straight edge of the elastic telescopic clamp 65 and the straight edge of the triangular helical tooth 641, the rotation of the wave ring disk 61 is restricted, and then the telescopic end of the elastic telescopic plate 62 will repeatedly extend out of the vertical sliding groove 47. When the telescopic end of the elastic telescopic plate 62 extends out, it will apply a certain pressure to the basalt concrete in the mold cavity 5, so that the concrete particles can be arranged more tightly, thereby reducing pores and air bubbles and improving the density of the concrete. (5) Simultaneously start the top pressing mechanism 7, and the second push rod 71 drives the annular top cover 72 to drive the annular pressure plate 73 to compact the basalt fiber concrete at the top of the mold cavity 5. (6) After the basalt fiber concrete is poured, it remains still for a period of time. At the same time, the operation of the drive component 46 is stopped, and the telescopic end of the elastic telescopic plate 62 is reset, driving the top pressing mechanism 7, the outer mold mechanism 3, and the inner mold mechanism 4 to reset upwards until the outer mold mechanism 3 and the inner mold mechanism 4 return to their initial state (e.g., Figure 4 As shown in the figure, the basalt fiber concrete pipe is now demolded.

[0040] During the demolding process, when the inner mold mechanism 4 resets and drives the inner mold column 44 to reset upward, the drive component 46 can drive the rotating rod 45 to rotate in the opposite direction. The rotating rod 45 eventually drives the inner mold column 44 to rotate. The inner mold column 44 drives the wave annular disk 61 to rotate through the elastic telescopic plate 62 (at this time, the elastic telescopic plate 62 does not extend or retract and is located in the vertical sliding groove 47). This allows the inner mold column 44 to rotate while moving upward, thereby effectively reducing the friction between the inner wall of the basalt fiber concrete pipe and the inner mold column 44. This prevents the basalt fiber concrete from adhering to the inner mold column 44 during the demolding process, reduces demolding resistance, and makes demolding smoother.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
