Description

Technical Field

[0001] The invention relates to the technical field of switch sleeper forming, in particular to a concrete track switch sleeper forming device. Background Art

[0002] At present, most reinforced concrete sleepers are produced using fixed-structure molds, that is, one mold can only produce one type of sleeper. For this reason, a switch sleeper mold with announcement number CN205310479U is disclosed. The mold includes two side plates, a bottom plate and an end plate. The end plates, side plates and bottom plate form a mold space. The bottom plate includes two fixed plates and a detachable plate. The two fixed plates are respectively fixed to the bottom of the opposite side plates. A sinking area is provided on the upper surface of the fixed plate near its inner edge along its length direction so that the inner side of the fixed plate forms a step shape. The two sides of the disassembly plate are stuck in the sinking area of ​​the two fixed plates and the upper surface of the disassembly plate is flush with the upper surface of the fixed plate. The width of the disassembly plate is adapted to the width between the sinking areas of the two fixed plates and the side surfaces of the disassembly plate are adapted to the side surfaces of the sinking area, so that after the disassembly plate is stuck in the sinking area, the fixed plate and the disassembly plate form a bottom plate. Bolt holes corresponding to the setting positions of the switch sleeper casings to be produced are provided on the disassembly plate. When producing switch sleepers of different models, only the disassembly plate needs to be replaced, which greatly reduces the investment in steel molds and reduces the steel mold library.

[0003] However, in actual use, we found that after the switch sleepers are formed and cured, they need to be sent to the stacking position for centralized storage. However, in the process of removing the switch sleepers, the assistance of external clamping equipment is required, that is, after the outer reinforcement frame, bottom plate and side plate are dismantled, the clamping equipment is used to clamp and position the switch sleepers on both sides or all around. If the pressure of the clamping equipment is too large or the force is uneven, it may damage the surface of the concrete switch sleeper or cause microcracks, affecting the durability and bearing capacity of the switch sleeper. If the pressure of the clamping equipment is insufficient, it may cause the switch sleeper to fall off, posing a safety hazard.

[0004] To this end, we propose a concrete track switch sleeper forming device. Summary of the Invention

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0019] Example 1 See also Figures 1-14 , the present invention provides a technical solution: The concrete track switch sleeper forming device includes a reinforcement frame 1 and multiple cavities 2. The reinforcement frame 1 and the cavity 2 are a structural combination of CN205310479U. Specifically, the reinforcement frame 1 is composed of a first reinforcement frame 1 and a second reinforcement frame 1, and the cavity 2 is composed of side plates, a bottom plate and an end plate, both of which can be adjusted to obtain mold spaces of different sizes. The device also includes: The substrate 3 is arranged at the bottom of the cavity 2 and is attached to the bottom of the cavity 2 to form a mold space with the cavity 2; A filling hole 9 is provided in the middle of the cavity 2. A plurality of filling holes 9 are provided, and all of the filling holes 9 are fan-shaped structures. A rotating rod 10, wherein the rotating rod 10 is rotatably disposed in the middle of the cavity 2; The collecting chamber 11 is provided at the bottom of the rotating rod 10 and is flush with the inner wall of the cavity 2. There are multiple collecting chambers 11, and the sizes of the multiple collecting chambers 11 are the same as the size of the filling hole 9. Therefore, when the concrete is poured, the collecting chamber 11 will not affect the filling; The inner wall of the bottom of the collecting chamber 11 is an inclined surface with a high outer surface and an inner surface. In this way, when rotating, the excess concrete in the cavity 2 can be stored in the collecting chamber 11 and will not flow out of the collecting chamber 11 at will, avoiding the need to cut off the excess part when pouring too much; The staff installs different reinforcement frames 1 and cavities 2 according to the size of the switch sleeper to obtain different switch sleeper molds, and then rotates the base plates 3 of different sizes according to the mold, applies sealant and release agent as needed, and then uses the filling hole 9 to fill the mold with concrete slurry. After filling, hold the rotating rod 10 and rotate it back and forth so that the bottom of the collecting chamber 11 is level with the position of the filling hole 9 on the top of the mold. At the same time, the excess concrete slurry is stored in the collecting chamber 11 and wait for the switch sleeper to be formed.

[0020] The base plate 3 includes a bottom plate frame 31 arranged at the bottom of the cavity 2, a plurality of movable ejector rods 32 are arranged on the bottom plate frame 31, and a switchable jacking assembly 4 is arranged on the bottom plate frame 31; The bottom plate frame 31 is composed of a bottom plate and a limiting frame around it. The height of the limiting frame is the same as the height of the unadjusted ejector pin 32, and the height of the limiting frame is lower than the height of the adjusted ejector pin 32. The bottom plate frame 31 and the ejector pin 32 are both fixed-size structures and cannot be adjusted during use, but can be replaced according to different mold sizes. In this solution, six ejector rods 32 are provided, each divided into two groups. In actual use, the number of ejector rods 32 and the number of each group can be adjusted according to the use situation without limitation. The ejector rods 32 are directly fitted with the cavity 2 and serve as the ground structure of the cavity 2. Because there are multiple ejector rods 32, there may be gaps between the ejector rods 32. In order to enhance the sealing performance of the connection between the ejector rods 32 and the ejector rods 32, sealant can be applied to the sides of the ejector rods 32 before assembly to seal the connection between the two. At the same time, in order to ensure the demoulding effect, some release agent can be pre-sprayed on the inside of the cavity 2 and the top of the ejector rods 32, such as a water-based release agent such as emulsified oil, or a fatty acid solvent-based release agent. The switchable lifting assembly 4 includes a plurality of rotating shafts 41 rotatably arranged on the base frame 31 , and each of the rotating shafts 41 is provided with an upper lifting member 5 ; In this embodiment, three rotating shafts 41 are provided, but not limited thereto, and the three rotating shafts 41 are respectively located in the middle and on both sides of the bottom frame 31, thereby ensuring effective lifting of the jack 32; The upper ejector 5 includes a plurality of ejector blocks 51 respectively provided on the rotating shaft 41 , and the plurality of ejector blocks 51 are in contact with the ejector rod 32 respectively; The number and position of the lifting blocks 51 on each rotating shaft 41 are the same, so as to accurately lift the required push rods 32. The number of lifting blocks 51 is the same as the number of push rods 32. Regardless of whether the push rods 32 are lifted by the lifting blocks 51, the lifting blocks 51 are always in contact with the push rods 32. Because the push rods 32 are divided into two groups in this solution, the lifting blocks 51 are also divided into two groups, that is, the lifting blocks 51 have two different initial positions. Specifically: The two sets of lifting blocks 51 are respectively arranged on the left and right sides of the rotating shaft 41 (not shown in the figure). By rotating the rotating shaft 41 to drive one set of lifting blocks 51, one set of push rods 32 can be pushed up. Similarly, the reverse rotation can also push up the other set of push rods 32.

[0021] During use, the staff installs different reinforcement frames 1 and cavities 2 according to the size of the switch sleeper to obtain different switch sleeper molds. Then, the base plates 3 of different sizes are rotated according to the molds, and multiple ejector pins 32 are placed in the base plates 3 so that the ejector pins 32 are placed above the lifting blocks 51. When the ejector pins 32 are placed and when the ejector pins 32 are not lifted, the two sets of lifting blocks 51 are on the left and right sides of the rotating shaft 41. At this time, all the ejector pins 32 are at the same height. Apply sealant and release agent as needed, then use the filling hole 9 to fill the mold with concrete slurry. After filling, hold the rotating rod 10 and rotate it back and forth so that the bottom of the collecting chamber 11 is level with the filling hole 9 on the top of the mold. At the same time, store the excess concrete slurry in the collecting chamber 11 and wait for the switch sleeper to be formed. Because the current cavity 2 is set up in reverse, the top cavity 2 and reinforcement frame 1 can be directly taken out upwards; Rotating the rotating shaft 41 can drive the jacking block 51 to rotate, and rotating the jacking block 51 can drive the jacking rod 32 thereon to move upward, thereby lifting the switch sleeper. The switch sleeper can be transported using the moved jacking rod 32 as a base without clamping the switch sleeper.

[0022] Example 2 See also Figure 5-10 , the present invention provides a technical solution: The concrete track switch sleeper forming device has a drive assembly 6 provided on the base frame 31 located on the side. A synchronizer 8 is provided between two adjacent base frames 31 along the axial direction of the rotating shaft 41. The drive assembly 6 includes a plurality of drive shafts 61 connected to the rotating shafts 41 respectively. The plurality of drive shafts 61 are connected by a belt transmission. An outer cover 62 is provided on the base frame plate, and a positioning member 7 is provided on the outer cover 62. Because molds are generally not cast individually, and most of them are made in multiples at one time, it is necessary to design a drive structure and a transmission structure that can synchronously adjust multiple rotating shafts 41; In this solution, the drive assembly 6 is arranged on one side of the base frame 31, so that a single drive assembly 6 and a synchronizer 8 can realize the lifting work of multiple switch sleepers along the axial direction of the rotating shaft 41, thereby improving work efficiency and reducing the number of drive structure settings; In order to ensure the synchronous rotation of the multiple drive shafts 61, a belt transmission structure composed of toothed pulleys can be used to avoid slipping during transmission; The positioning member 7 includes a guide tube 71 disposed in the outer cover 62, a locking block 72 slidably disposed in the guide tube 71, a spring 73 disposed on the locking block 72, and an adjustment rod 74 extending to the outside of the outer cover 62 disposed on the locking block 72. The drive shaft 61 is provided with a plurality of locking slots 75; In this solution, only a positioning member 7 is provided on the outer side of a single drive shaft 61. In actual use, the number of positioning members 7 can be increased according to the use situation. Since there are only two sets of ejector rods 32 in this solution, the locking slot 75 is set to a plane whose four sides are in contact with the locking block 72. The inner wall of the guide tube 71 and the locking block 72 have the same shape and can prevent the locking block 72 from rotating. When in use, the locking block 72 can be disengaged from the locking slot 75 by stretching the adjustment rod 74 and compressing the spring 73. At this time, the drive shaft 61 can rotate. The synchronizer 8 includes a polygonal rod 81 disposed between the two rotating shafts 41 . Two adjacent rotating shafts 41 along the axis of the rotating shaft 41 are each provided with a polygonal notch 82 , and the polygonal rod 81 is located in the two polygonal notches 82 . By connecting the polygonal rod 81 and the polygonal notch 82 , two adjacent rotating shafts 41 along the axial direction of the rotating shaft 41 can rotate synchronously, thereby realizing the synchronous lifting of multiple switch sleepers.

[0023] When the locking block 72 is disengaged from the locking slot 75 , the driving shaft 61 can be rotated. The rotation of the driving shaft 61 drives the multiple rotating shafts 41 on the same base frame 31 to rotate through the belt transmission. Driven by the polygonal notch 82 and the polygonal rod 81 , the multiple rotating shafts 41 along the axial direction of the rotating shaft 41 can be driven to rotate synchronously. After rotation, the adjusting rod 74 is released, and the spring 73 is reset to cooperate with the limit of the locking block 72 and the locking slot to realize the locking positioning of each structure.

[0024] Example 3 See also Figure 12-13 , the present invention provides a technical solution: The concrete track switch sleeper forming device is provided with a guide block 12 on the base frame 31, and a guide slot 13 is provided on the top rod 32. The setting of the guide block 12 and the guide slot 13 can improve the accurate placement of the top rod 32, which can avoid large gaps between the top rods 32 and can also guide the top rod 32 when it is raised or lowered.

[0025] Example 4 See also Figures 8-14 , the present invention provides a technical solution: Concrete track switch sleeper forming device, the top rod 32 is provided with a rectangular groove 14, and the rectangular groove 14 is provided with a demoulding section 15, a middle section 16 and a demoulding section 2 17; The dimensions of the first and second demolding sections 15, 17 are adjusted according to the dimensions of the mold. The requirement is that the first and second demolding sections 15, 17 fit the sides of the mold respectively, but do not contact the cavity 2 of the switch sleeper. The middle section 16 is the remaining space in the rectangular groove 14 after removing the first and second demolding sections 15, 17. The middle section 16 can be directly inserted as a whole, or it can be composed of multiple sections, with the standard being that the remaining space can be filled. The demoulding section 15 and the demoulding section 2 17 are both chamfered, and the ejector rod 32 is provided with a plurality of connecting slots 18, and a lifting rod 19 is movably inserted into the connecting slots 18; In order to enhance the sealing performance of the connection between the first demoulding section 15, the middle section 16 and the second demoulding section 17, sealant can be applied to the side of the rectangular groove 14 before assembly to seal the connection between the structures. A large number of connecting slots 18 are provided to accommodate the first demoulding section 15 and the second demoulding section 17 of different sizes. After the first demoulding section 15, the middle section 16 and the second demoulding section 17 are placed in the rectangular groove 14, the connection position between the connecting slots 18 and the cavity 2 will be sealed, so it will not affect the molding of the switch sleeper. The lifting rod 19 is composed of a middle rod body 20 and detachable hooks 21 on both sides. The rod body 20 is adapted to the connecting slot 18. In addition, during the lifting, the number of insertions of the lifting rod 19 is not limited and is adjusted according to the weight of the switch sleeper. Before using the lifting rod 19, first remove the hook 21 on one side, and then insert the rod body 20. The rod body 20 will touch the chamfered side of the demoulding section 15 or the demoulding section 2 17 to lift it up, so that the cavity 2 on that side will rise slightly, making it easier to remove the cavity 2 later. After the rod body 20 passes through the connecting slot 18, the hook 21 can be installed.

[0026] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
