Description

Technical Field

[0001] This invention relates to the field of turnout sleeper forming technology, specifically to a concrete track turnout sleeper forming device. Background Technology

[0002] Currently, reinforced concrete railway sleepers are mostly produced using fixed-structure molds, meaning that one mold can only produce one type of sleeper. Therefore, a turnout sleeper mold (announcement number CN205310479U) is described. The mold includes two side plates, a bottom plate, and end plates. These plates form the 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. The upper surface of the fixed plates has a recessed area along its length near its inner edge, creating a stepped shape on the inner side of the fixed plates. The two sides of the detachable plate are inserted into the recessed areas of the two fixed plates, and the upper surface of the detachable plate is flush with the upper surface of the fixed plates. The width of the detachable plate is adapted to the width between the recessed areas of the two fixed plates, and the side of the detachable plate is adapted to the side of the recessed area. After the detachable plate is inserted into the recessed area, the fixed plates and the detachable plate form a base plate. The detachable plate has bolt holes corresponding to the installation position of the turnout sleeper sleeve to be produced. When producing different models of turnout sleepers, only the detachable plate needs to be replaced, which greatly reduces the investment in steel molds and also reduces the steel mold warehouse.

[0003] However, in actual use, we found that after the turnout sleepers are formed and cured, they need to be sent to the stacking location for centralized storage. However, during the removal of the turnout sleepers, external clamping equipment is required. That is, after the outer reinforcing frame, base plate and side plates are disassembled, clamping equipment is used to clamp and position the turnout sleepers on both sides or around. If the clamping equipment has too much pressure or uneven force, it may damage the surface of the concrete turnout sleeper or cause micro-cracks, affecting the durability and load-bearing capacity of the turnout sleeper. If the clamping equipment has insufficient pressure, it may cause the turnout sleeper to fall off, posing a safety hazard.

[0004] Therefore, we propose a concrete track turnout sleeper forming device. Summary of the Invention

[0005] One of the technical problems to be solved in this application is: how to design a concrete track turnout sleeper molding device that is easy to demold and transport.

[0006] To address the aforementioned technical problems, embodiments of this application provide a concrete track turnout sleeper forming device, including a reinforcing frame and multiple cavities, and further comprising:

[0007] A substrate, wherein the substrate is disposed at the bottom of the cavity;

[0008] A filling hole is provided in the middle of the cavity;

[0009] A rotating rod, which is rotatably positioned in the middle of the cavity;

[0010] The collection cavity is located at the bottom of the rotating rod and is flush with the inner wall of the cavity.

[0011] In some embodiments, the substrate includes a base plate frame disposed at the bottom of the cavity, the base plate frame being provided with a plurality of movable top rods, and a switchable lifting assembly being provided on the base plate frame.

[0012] In some embodiments, the switchable lifting assembly includes a plurality of rotating shafts rotatably mounted on a base plate frame, each of which is provided with an upper lifting member.

[0013] In some embodiments, the upper support includes a plurality of lifting blocks respectively disposed on a rotating shaft, and the plurality of lifting blocks respectively contact the top rod.

[0014] In some embodiments, a drive assembly is provided on the base plate frame located on the side, and a synchronizing element is provided between two adjacent base plates along the axial direction of the rotation axis. The drive assembly includes a plurality of drive shafts connected to each other by rotation axes, and the plurality of drive shafts are connected by belt drive. An outer cover is provided on the base plate, and a positioning element is provided on the outer cover.

[0015] In some embodiments, the positioning element includes a guide tube disposed inside the outer cover, a locking block slidably disposed inside the guide tube, a spring disposed on the locking block, an adjusting rod extending to the outside of the outer cover disposed on the locking block, and a plurality of locking slots provided on the drive shaft.

[0016] In some embodiments, the synchronizing element includes a polygonal rod disposed between two rotating shafts, with polygonal slots provided on both adjacent rotating shafts along the axial direction of the rotating shafts, and the polygonal rod located within the two polygonal slots.

[0017] In some embodiments, a guide block is provided on the base plate frame, and a guide groove is provided on the top rod.

[0018] In some embodiments, a rectangular groove is provided on the top rod, and a demolding section one, an intermediate section and a demolding section two are provided in the rectangular groove.

[0019] In some embodiments, both the first demolding section and the second demolding section are chamfered, and the top rod is provided with multiple connecting slots, in which a lifting rod is movably inserted.

[0020] The present invention has at least the following beneficial effects:

[0021] 1. The cavity is used upside down, which facilitates demolding after the sleeper is formed and cured. At the same time, the base plate is equipped with a switchable lifting component and a lifting rod, which can further facilitate the subsequent placement of the sleeper and avoid the clamping structure directly contacting the sleeper surface, which would cause the contact point to be squeezed and broken.

[0022] 2. The combination of multiple jacking rods and a switchable jacking assembly allows multiple jacking rods to be used in multiple groups, improving the utilization rate of the jacking rods. Attached Figure Description

[0038] 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.

[0039] Example 1

[0040] Please see Figures 1-14 The present invention provides a technical solution:

[0041] A concrete track turnout sleeper molding device includes a reinforcing frame 1 and multiple cavities 2. The reinforcing frame 1 and cavities 2 are structural combinations according to CN205310479U. Specifically, the reinforcing frame 1 is composed of a first reinforcing frame 1 and a second reinforcing frame 1, and the cavity 2 is composed of a side plate, a bottom plate, and an end plate. Both are adjustable to obtain mold spaces of different sizes. The device also includes:

[0042] The substrate 3 is disposed at the bottom of the cavity 2 and fits against the bottom of the cavity 2 to form a mold space in conjunction with the cavity 2;

[0043] The filling hole 9 is located in the middle of the cavity 2. There are multiple filling holes 9, and all of the multiple filling holes 9 are fan-shaped structures.

[0044] Rotating rod 10, which is rotatably disposed in the middle of cavity 2;

[0045] The collection chamber 11 is located at the bottom of the rotating rod 10 and is flush with the inner wall of the cavity 2. Multiple collection chambers 11 are provided, and the size of the multiple collection chambers 11 is the same as the size of the filling hole 9, so that the collection chambers 11 will not affect the filling when adding concrete.

[0046] The bottom inner wall of the collecting cavity 11 is an inclined surface with the outside higher than the inside. This way, when rotating, excess concrete in the cavity 2 can be stored in the collecting cavity 11 and will not flow out of the collecting cavity 11 at will. This avoids the need to cut off the excess part of the fork sleeper when too much concrete is poured.

[0047] Workers install different reinforcing frames 1 and cavities 2 according to the size of the turnout sleeper to obtain different turnout sleeper molds. Then, they rotate base plates 3 of different sizes according to the mold, apply sealant and release agent as needed, and then pour concrete slurry into the mold through the filling hole 9. After filling, they hold the rotating rod 10 and rotate it back and forth to make the bottom of the collecting cavity 11 level with the filling hole 9 on the top of the mold. At the same time, the excess concrete slurry is stored in the collecting cavity 11, waiting for the turnout sleeper to be formed.

[0048] The base plate 3 includes a base plate frame 31 disposed at the bottom of the cavity 2, a plurality of movable top rods 32 disposed on the base plate frame 31, and a switchable lifting assembly 4 disposed on the base plate frame 31;

[0049] The base plate frame 31 consists of a base plate and surrounding limiting frames. The height of the limiting frames is the same as the height of the unadjusted ejector pin 32, and the height of the limiting frames is lower than the height of the adjusted ejector pin 32. Both the base plate frame 31 and the ejector pin 32 are fixed-size structures and cannot be adjusted during use, but they can be replaced according to different mold sizes.

[0050] In this design, there are six ejector pins 32, divided into two groups. In actual use, the number of ejector pins 32 and the number of each group can be adjusted according to the usage situation without limitation. The ejector pins 32 are directly attached to the cavity 2 and serve as the ground structure of the cavity 2. Since there are multiple ejector pins 32, there may be gaps between them. In order to enhance the sealing of the connection between the ejector pins 32, sealant can be applied to the side of the ejector pins 32 before assembly to seal the connection. At the same time, in order to ensure the demolding effect, some release agent, such as water-based release agent like emulsified oil or fatty acid solvent-based release agent, can be sprayed in advance inside the cavity 2 and on the top of the ejector pins 32.

[0051] The switching lifting assembly 4 includes multiple rotating shafts 41 rotatably mounted on the base plate frame 31, and each rotating shaft 41 is provided with an upper lifting component 5.

[0052] In this scheme, there are three rotating shafts 41, but not limited to three. The three rotating shafts 41 are located in the middle and on both sides of the base plate frame 31, respectively, so as to ensure effective lifting of the top rod 32.

[0053] The upper support 5 includes a plurality of lifting blocks 51 respectively disposed on the rotating shaft 41, and the plurality of lifting blocks 51 respectively contact the top rod 32;

[0054] The number and position of the lifting blocks 51 on each rotating shaft 41 are identical, thus accurately lifting the required lifting rod 32. The number of lifting blocks 51 is the same as the number of lifting rods 32. Regardless of whether the lifting rod 32 is lifted by the lifting block 51, the lifting block 51 is always in contact with the lifting rod 32. Because the lifting rods 32 are divided into two groups in this scheme, the lifting blocks 51 are also divided into two groups, that is, the lifting blocks 51 have two different initial positions, specifically:

[0055] Two sets of lifting blocks 51 are respectively set on the left and right sides of the rotating shaft 41 (not in the illustrated state). By rotating the rotating shaft 41, one set of lifting blocks 51 can be driven to lift one set of lifting rods 32. Similarly, rotating in the opposite direction can lift the other set of lifting rods 32.

[0056] During use, the staff installs different reinforcing frames 1 and cavities 2 according to the size of the turnout sleeper to obtain different turnout sleeper molds. Then, according to the mold, the base plate 3 of different sizes is rotated, and multiple push rods 32 are placed in the base plate 3 so that the push rods 32 are placed above the lifting block 51. When the push rods 32 are placed and when the push rods 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 push rods 32 are at the same height.

[0057] Apply sealant and release agent as needed, then pour concrete slurry into the mold through the filling hole 9. After filling, hold the rotating rod 10 and rotate it back and forth so that the bottom of the collecting cavity 11 is level with the filling hole 9 at the top of the mold. At the same time, store the excess concrete slurry into the collecting cavity 11 and wait for the forklift to be formed. Since the current cavity 2 is set in the opposite direction, the top cavity 2 and the reinforcing frame 1 can be taken out directly upwards.

[0058] Rotating the rotating shaft 41 will drive the lifting block 51 to rotate. The rotation of the lifting block 51 will drive the lifting rod 32 on it to move upward, thereby lifting the forklift. The forklift can then be transported using the upward-moving lifting rod 32 as a base, without the need to clamp the forklift.

[0059] Example 2

[0060] Please see Figures 5-10 The present invention provides a technical solution:

[0061] A concrete track turnout sleeper forming device has a drive assembly 6 installed on the base plate frame 31 located on the side. A synchronizing element 8 is installed between two adjacent base plate frames 31 along the axial direction of the rotation shaft 41. The drive assembly 6 includes multiple drive shafts 61 connected to the rotation shaft 41 respectively. The multiple drive shafts 61 are connected by belt drive. An outer cover 62 is installed on the base plate, and a positioning element 7 is installed on the outer cover 62.

[0062] Because molds are generally not cast individually, but are mostly made in multiples at once, it is necessary to design a drive structure and transmission structure for synchronously adjusting multiple rotating shafts 41.

[0063] This solution places the drive assembly 6 on one side of the base plate frame 31, so that the lifting of multiple fork sleepers along the axial direction of the rotating shaft 41 can be achieved by using a single drive assembly 6 in conjunction with the synchronizing element 8, thereby improving work efficiency and reducing the setup of the drive structure.

[0064] To ensure the synchronous rotation of multiple drive shafts 61, a belt drive structure consisting of toothed pulleys can be used to avoid slippage during transmission.

[0065] The positioning component 7 includes a guide tube 71 disposed inside the outer cover 62, a locking block 72 slidably disposed inside the guide tube 71, a spring 73 disposed on the locking block 72, an adjusting rod 74 extending to the outside of the outer cover 62 disposed on the locking block 72, and a plurality of locking slots 75 provided on the drive shaft 61.

[0066] In this solution, only a positioning component 7 is added to the outside of a single drive shaft 61. In actual use, the number of positioning components 7 can be increased according to the usage. Since there are only two sets of push rods 32 in this solution, the locking slot 75 is set as a plane with four sides that fits against the locking block 72.

[0067] The inner wall of the guide tube 71 has the same shape as the locking block 72 and can prevent the locking block 72 from rotating. In use, the locking block 72 can be disengaged from the locking slot 75 by stretching the adjusting rod 74 and compressing the spring 73. At this time, the drive shaft 61 can rotate.

[0068] The synchronizing element 8 includes a polygonal rod 81 disposed between two rotating shafts 41. Two adjacent rotating shafts 41 are provided with polygonal slots 82 along the axial direction of the rotating shafts 41, and the polygonal rod 81 is located in the two polygonal slots 82.

[0069] By connecting the polygonal rod 81 and the polygonal slot 82, two adjacent rotating shafts 41 can rotate synchronously along the axial direction of the rotating shaft 41, thereby enabling the synchronous lifting of multiple fork sleepers.

[0070] By stretching the adjusting rod 74 and compressing the spring 73, the locking block 72 can be disengaged from the locking slot 75. At this time, the drive shaft 61 can rotate. The rotation of the drive shaft 61 drives multiple rotating shafts 41 on the same base plate frame 31 to rotate via belt drive. Under the drive of the polygonal slot 82 and the polygonal rod 81, 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 returns to its original position. With the locking block 72 and the locking slot in place, the locking and positioning of each structure can be achieved.

[0071] Example 3

[0072] Please see Figures 12-13 The present invention provides a technical solution:

[0073] The concrete track turnout sleeper forming device has a guide block 12 on the base plate frame 31 and a guide groove 13 on the top rod 32. The guide block 12 and the guide groove 13 can improve the accurate insertion of the top rod 32, avoid large gaps between the top rods 32, and guide the top rod 32 when it is raised and lowered.

[0074] Example 4

[0075] Please see Figures 8-14 The present invention provides a technical solution:

[0076] A concrete track turnout sleeper forming device, wherein a rectangular groove 14 is provided on the top rod 32, and a demolding section 15, an intermediate section 16 and a demolding section 2 17 are provided in the rectangular groove 14;

[0077] The dimensions of demolding section 15 and demolding section 2 17 are adjusted according to the dimensions of the mold. The requirement is that demolding section 15 and demolding section 2 17 should fit against the sides of the mold respectively, but not contact the cavity 2 of the forklift. The middle section 16 is the remaining space in the rectangular groove 14 after removing demolding section 15 and demolding section 2 17. The middle section 16 can be inserted as a whole or multiple sections combined, with the standard being that the remaining space can be filled.

[0078] Both the first demolding section 15 and the second demolding section 17 are chamfered. The top rod 32 is provided with multiple connecting slots 18, and a lifting rod 19 is movably inserted into the connecting slots 18.

[0079] To enhance the sealing of the connection between demolding section 15, intermediate section 16 and demolding section 2 17, sealant can be applied to the side of the rectangular groove 14 before assembly to seal the connection of each structure. There are a large number of connecting slots 18 to accommodate demolding sections 15 and 2 17 of different sizes. After demolding sections 15, intermediate section 16 and demolding section 2 17 are placed into the rectangular groove 14, the connection slots 18 and the cavity 2 will be closed, so it will not affect the molding of the forklift sleeper.

[0080] The lifting boom 19 consists of a central boom 20 and two detachable hooks 21 on both sides. The boom 20 is compatible with the connecting slot 18. In addition, the number of booms 19 inserted during lifting is not limited and can be adjusted according to the weight of the forklift sleeper.

[0081] Before using the lifting rod 19, remove the hook 21 on one side and then insert the rod body 20. When the rod body 20 contacts the chamfered side of the demolding section 15 or demolding section 27, it will lift it up, causing the cavity 2 on that side to 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.

[0082] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
