Description

Technical Field

[0001] This utility model relates to the field of railway sleeper production technology, specifically a prestressed railway sleeper mold. Background Technology

[0002] Currently, the prestressed concrete long sleepers used in China's railways, subways, and international railways typically come in two forms: those with shoulders and those without shoulders. Both types have various models. When prefabricating sleepers, steel molds for prestressed concrete sleepers are generally used for casting. Usually, a fixed mold is used for producing one model of prestressed concrete long sleeper.

[0003] In existing technologies, molds are generally separate. Some molds can cast two or more prestressed concrete long sleepers at the same time, but in most cases, the number is fixed during casting. That is, multiple molds are separate and cannot be spliced ​​or combined. Furthermore, after pouring concrete, uneven concrete vibration is prone to occur, resulting in the concrete sleepers failing to meet design requirements in terms of strength and durability. To address these issues, we propose a prestressed sleeper mold to solve the shortcomings of existing technologies. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that molds are generally separate. Some molds can cast two or more prestressed concrete long sleepers at the same time, but in most cases, the number is fixed during casting. That is, multiple molds are separate and cannot be spliced ​​together or combined.

[0005] To address the aforementioned technical problems, this application provides a prestressed railway sleeper mold, comprising a base, a vibrating assembly disposed inside the base, an mounting plate disposed at the top of the base, a mold shell disposed at the top of the mounting plate, tensioning ends fixedly connected to both ends of the mold shell, locking blocks fixedly connected to both ends of one side of each tensioning end, locking grooves formed inside the locking blocks, a fixing block fixedly connected to the other side of each tensioning end, a locking assembly disposed inside the fixing block, a partition fixedly connected to the inside of the mold shell, a limit strip fixedly connected to one side of the top of the mounting plate, a screw rotatably connected to the other side of the top of the mounting plate, a clamping plate threadedly connected to the outer side of the screw, and a throttle handle fixedly connected to one end of the screw.

[0006] In some embodiments, the vibrating assembly includes a transmission rod, a cam, and a connecting rod. The outer side of the transmission rod is rotatably connected to the inner wall of the base. There are several cams, the outer side of which is rotatably connected to one end of the transmission rod. The bottom end of the connecting rod is rotatably connected between two cams.

[0007] In some embodiments, the vibrating assembly further includes an impact block, a vibrating block, and a limiting rod. The inner wall of the impact block is rotatably connected to the bottom end of the connecting rod, the bottom end of the vibrating block is fixedly connected to the bottom end of the mounting plate, the bottom end of the limiting rod is fixedly connected to the bottom end of the impact block, and the top end of the limiting rod is slidably connected to the inner wall of the vibrating block.

[0008] In some embodiments, the vibrating assembly further includes a rigid spring and a drive motor. The rigid spring is of a plurality of sizes. The bottom end of the rigid spring is fixedly connected to the top end of the base, and the top end of the rigid spring is fixedly connected to the bottom end of the mounting plate. One end of the drive motor is fixedly connected to the outside of the base, and the output shaft of the drive motor is fixedly connected to one end of the transmission rod.

[0009] In some embodiments, the snap-fit ​​assembly includes a slot, a groove, and a movable plate. There are two slots, which are formed at both ends of the interior of the fixed block. The type of the slot matches the type of the slot. The groove is formed between the two slots. There are two movable plates, which are slidably connected to both ends of the interior of the groove.

[0010] In some embodiments, the snap-fit ​​assembly further includes a snap-fit ​​block, a connecting plate, and a return spring. One end of the snap-fit ​​block is fixedly connected to the outside of the movable plate, and the snap-fit ​​block matches the model of the snap-fit ​​groove.

[0011] In some embodiments, the snap-fit ​​assembly further includes a groove and a slider. There are two grooves, which are formed on the inner walls of both sides of the groove. The slider is fixedly connected to both sides of the movable plate and is located inside the groove. The slider is slidably connected to the groove.

[0012] This utility model has at least the following beneficial effects:

[0013] I. This utility model, through its snap-fit ​​assembly, enables the splicing of two molds. Multiple molds can be combined as needed. During splicing, first, push the two connecting plates on the fixed block on the outer side of one mold shell to bring the two movable plates closer together, while simultaneously retracting the snap-fit ​​block into the groove. Then, insert the snap-fit ​​block on the outer side of the other mold shell into the snap-fit ​​groove on the outer side of the first mold shell. After releasing the connecting plates, the return spring resets due to the force, which can drive the movable plate and snap-fit ​​block to reset, allowing the snap-fit ​​block to enter the snap-fit ​​groove. This allows the two molds to be spliced, improving flexibility and increasing casting speed.

[0014] II. This utility model, through its set vibration assembly, can uniformly vibrate the concrete inside the mold. By starting the drive motor, the transmission rod rotates, which in turn drives the cam to rotate and pushes the connecting rod to move. This causes the top of the connecting rod to push the impact block upward, thereby causing the impact block to strike the vibration block. As the cam rotates, the impact block can continuously strike the vibration block. In conjunction with the rigid spring, the mounting plate can vibrate, thereby vibrating the outer shell of the mold.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6 As shown, this utility model provides a technical solution: a prestressed sleeper mold, including a base 1, a vibrating component 2 inside the base 1, an installation plate 3 at the top of the base 1, a mold shell 4 at the top of the installation plate 3, tensioning ends 5 fixedly connected to both ends of the mold shell 4, a locking block 6 fixedly connected to both ends of one side of the tensioning end 5, a locking groove 7 opened inside the locking block 6, a fixing block 8 fixedly connected to the other side of the tensioning end 5, a locking component 9 inside the fixing block 8, a partition plate 10 fixedly connected inside the mold shell 4, a limit strip 11 fixedly connected to one side of the top of the installation plate 3, a screw 12 rotatably connected to the other side of the top of the installation plate 3, a clamping plate 13 threadedly connected to the outer side of the screw 12, and a throttle handle 14 fixedly connected to one end of the screw 12;

[0025] The snap-fit ​​component 9 allows two molds to be joined together, and multiple molds can be combined as needed. The combined mold is then placed on the mounting plate 3. By rotating the handle 14, the screw 12 can be moved, which in turn moves the clamping plate 13 horizontally. With the help of the limiting strip 11, the combined mold shell 4 can be clamped and fixed. Finally, the concrete inside the mold can be uniformly vibrated by the vibration component 2.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, the vibratory assembly 2 includes a transmission rod 201, a cam 202, a connecting rod 203, an impact block 204, a vibrating block 205, a limiting rod 206, a rigid spring 207, and a drive motor 208. The outer side of the transmission rod 201 is rotatably connected to the inner wall of the base 1. Several cams 202 are present, with their outer sides rotatably connected to one end of the transmission rod 201. The bottom end of the connecting rod 203 is rotatably connected between two cams 202. The inner side of the impact block 204 is rotatably connected to the bottom end of the connecting rod 203. The vibrating block... The bottom end of 205 is fixedly connected to the bottom end of the mounting plate 3, the bottom end of the limiting rod 206 is fixedly connected to the bottom end of the impact block 204, the top end of the limiting rod 206 is slidably connected to the inner wall of the vibration block 205, there are several rigid springs 207, the bottom end of the rigid spring 207 is fixedly connected to the top end of the base 1, the top end of the rigid spring 207 is fixedly connected to the bottom end of the mounting plate 3, one end of the drive motor 208 is fixedly connected to the outside of the base 1, and the output shaft of the drive motor 208 is fixedly connected to one end of the transmission rod 201;

[0027] By starting the drive motor 208, the transmission rod 201 is driven to rotate, which in turn drives the cam 202 to rotate and pushes the connecting rod 203 to move. This causes the top of the connecting rod 203 to push the impact block 204 upward, thereby causing the impact block 204 to strike the vibration block 205. As the cam 202 rotates, the impact block 204 can continuously strike the vibration block 205. In conjunction with the rigid spring 207, the mounting plate 3 can vibrate, thereby vibrating the mold shell 4.

[0028] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the snap-fit ​​assembly 9 includes a snap-fit ​​slot 901, a groove 902, a movable plate 903, a snap-fit ​​block 904, a connecting plate 905, a return spring 906, a sliding groove 907, and a slider 908. There are two snap-fit ​​slots 901, which are located at both ends of the interior of the fixed block 8. The type of the snap-fit ​​slots 901 matches that of the snap-fit ​​block 6. The groove 902 is located between the two snap-fit ​​slots 901. There are two movable plates 903, which are slidably connected to both ends of the interior of the groove 902. One of the snap-fit ​​blocks 904... One end is fixedly connected to the outside of the movable plate 903. The snap-fit ​​block 904 matches the model of the snap-fit ​​groove 7. One end of the connecting plate 905 is fixedly connected to the outside of the movable plate 903. The two ends of the return spring 906 are respectively fixedly connected to the outside of the two movable plates 903. There are two slide grooves 907. The slide grooves 907 are opened on the inner walls of both sides of the groove 902. The slider 908 is fixedly connected to both sides of the movable plate 903. The slider 908 is located inside the slide groove 907. The slider 908 is slidably connected to the slide groove 907.

[0029] During assembly, first push the two connecting plates 905 on the outer fixing block 8 of one of the mold shells 4 to bring the two movable plates 903 closer together, and at the same time, retract the locking block 904 into the groove 902. Then, insert the locking block 6 on the outer side of the other mold shell 4 into the locking groove 901 on the outer side of the mold shell 4. After releasing the connecting plate 905, the locking block 904 is reset and enters the locking groove 7, so that the two mold shells 4 can be assembled. When the locking block 904 moves, it can drive the slider 908 to slide inside the sliding groove 907, thereby increasing stability.

[0030] Working principle: When assembling the molds, first push the two connecting plates 905 on one of the mold shells 4, which can drive the two movable plates 903 to move. When the two connecting plates 905 are pushed in opposite directions, the two movable plates 903 can be brought closer to each other, and the return spring 906 is compressed by force. At the same time, the locking block 904 is moved, which can be retracted into the groove 902. Then, the locking block 6 on the outside of the other mold shell 4 is inserted into the locking groove 901 on the outside of the mold shell 4. After releasing the connecting plate 905, the return spring 906 is reset by force, which can drive the movable plate 903 and the locking block 904 to reset, so that the locking block 904 enters the locking groove 7, and the two molds can be assembled. Multiple molds can be combined as needed.

[0031] After the mold shell 4 is assembled, it is placed on the mounting plate 3. By rotating the handle 14, the screw 12 is moved, which in turn moves the clamping plate 13 horizontally. With the help of the limiting strip 11, the assembled mold shell 4 can be clamped and fixed. After adding concrete into the mold shell 4, the drive motor 208 is started, which drives the transmission rod 201 to rotate. At the same time, the cam 202 rotates and pushes the connecting rod 203 to move. The top of the connecting rod 203 pushes the impact block 204 upward, which in turn causes the impact block 204 to strike the vibration block 205. As the cam 202 rotates, the impact block 204 continuously strikes the vibration block 205. With the help of the rigid spring 207, the mounting plate 3 vibrates, which in turn vibrates the mold shell 4, and can evenly vibrate the concrete inside the mold.
