Description

Technical Field

[0001] The present invention relates to the technical field of the production of steel railway turnouts and crossover slabs, and specifically to a forming mold for steel railway turnouts and crossover slabs. Background Technique

[0002] A steel railway turnout is a device used for the conversion of railway lines. A precast slab for a crossover is a precast slab used to support the crossover structure. Both are used in railway construction and maintenance. A turnout is a line connection device that enables locomotives and rolling stocks to transfer from one track to another, and it is also one of the weak links of the track. It is usually laid in large quantities at stations and marshalling yards. With turnouts, the passing capacity of the line can be fully utilized. Even on a single-track railway, by laying turnouts and building a turnout track longer than the train length, trains can run in opposite directions.

[0003] The precast slabs of steel railway turnouts and crossovers are used in railway construction and maintenance. When producing such precast slabs, molds are required for casting and forming. However, the turnout track slabs and crossovers are complex and variable, with different sizes and dimensions for each slab, and different positions for the nail hole distances. A set of steel molds must be invested for each slab, resulting in a large number of molds, high costs, and significant investment in mold costs. Moreover, when forming the precast slabs, a vibrator is needed to eliminate air bubbles during the forming of concrete. However, during the vibration process, the vibration sequence and speed vary at different locations, and the concrete cannot be vibrated quickly, easily leading to incomplete vibration, resulting in voids or honeycombing on the surface and internal damage to the products. In addition, the efficiency of manual vibration is relatively low. Based on this, a forming mold for steel railway turnouts and crossover slabs is proposed. Summary of the Invention

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 - 12, the present invention provides a technical solution: a forming mold for a precast slab of a steel railway turnout and a crossover, comprising a long side mold 1, a short side mold 2, a bottom mold 4, a telescopic cushion plate 5, an embedded sleeve 12, a balanced vibration mechanism 13, a bottom vibration plate 14 and a reserved forming mold 15. A number of rubber buffer column plates 8 are fixedly installed on the outer side of the bottom mold 4, a number of vibration motor plates 7 are fixedly installed on the outer side of the bottom mold 4, a number of limit sliding plates 401 are fixedly installed on the top of the bottom mold 4, a number of mounting covers 402 are movably installed on the top of the limit sliding plates 401. A number of reserved mounting holes 405 are formed on the top of the limit sliding plate 401 located in the middle of the bottom mold 4, a number of side mounting holes II 404 are formed on the outer side of the top of the bottom mold 4, a number of sinking docking holes 403 are formed on the top of the bottom mold 4, a number of sinking waist groove holes 406 are formed at the bottom of the sinking docking holes 403, and a number of limit sliding platforms 3 are fixedly installed on the outer side of the bottom mold 4. The telescopic cushion plate 5 is placed on the opposite sides of the long side mold 1 and the short side mold 2. A number of vertical positioning pin holes 9 are formed on the top of the long side mold 1, and a number of horizontal positioning pin holes 6 are formed inside the long side mold 1 and the telescopic cushion plate 5.

[0034] A positioning bolt 11 is threadedly connected to the inner side of the embedded sleeve 12. A rotary plug 10 is movably sleeved on the outer side of the positioning bolt 11. A waist groove limiting piece 1001 is fixedly installed at the bottom of the rotary plug 10. A number of threaded strips are fixedly installed on the outer side of the embedded sleeve 12.

[0035] The working principle of the above technical solution: During operation, the long side mold 1 and the short side mold 2 are placed in a rectangular enclosure on the top of the bottom mold 4. Then, the distance between the long side mold 1 and the short side mold 2 is adjusted as needed. The position of the long side mold 1 is fixed by inserting bolts into the vertical positioning pin holes 9 and the side mounting holes II 404. Then, the telescopic cushion plate 5 is placed between the long side mold 1 and the short side mold 2 and fixed by inserting bolts into the horizontal positioning pin holes 6. Then, the steel bars are placed on the top of the bottom mold 4 and tied up. Then, the rotary plug 10 and the waist groove limiting piece 1001 are placed inside the sinking docking holes 403 and the sinking waist groove holes 406, and the embedded sleeve 12 is placed on the top of the rotary plug 10. Then, the positioning bolt 11 passes through the rotary plug 10 and the waist groove limiting piece 1001 and is threadedly connected into the embedded sleeve 12. Finally, pouring is carried out. The cement is filled inside the long side mold 1. Finally, a vibration motor is installed through the vibration motor plate 7 or the bottom mold 4 is vibrated by the balanced vibration mechanism 13. The overall solution can be adjusted, increasing the relative stability of the structure.

[0036] In another embodiment, such as Figures 1 - 4As shown, the number of rubber buffer column plates 8 and vibration motor plates 7 is six each, and the vibration motor plates 7 and the rubber buffer column plates 8 are symmetrically and evenly distributed linearly in a rectangle on the outside of the bottom mold 4. The number of limit sliding tables 3 is eight, and the eight limit sliding tables 3 are evenly distributed in equal parts in a rectangle on the outside of the long side 1 of the side mold.

[0037] The vibration motor plate 7 facilitates the installation of the vibration motor, and the rubber buffer column plate 8 facilitates the connection with the vibration mechanism 13 or the connection of shock-absorbing rubber columns, which is convenient for support and placement. The limit sliding table 3 is used for fixing and guiding.

[0038] In another embodiment, as Figure 2 shown, the number of long sides 1 of the side mold is two, and the number of short sides 2 of the side mold is two. The two long sides 1 of the side mold and the short sides 2 of the side mold are evenly distributed in a rectangle on the top of the long side 1 of the side mold. The limit sliding plates 401 are evenly distributed linearly on the top of the bottom mold 4. The short sides 2 of the side mold are slidably sleeved on the outside of the limit sliding plates 401. A number of operation openings 102 are provided on the outside of the long side 1 of the side mold, and a number of first side mounting holes 101 are provided on the opposite side of the long side 1 of the side mold. The specification dimensions of the first side mounting holes 101 are adapted to the specification dimensions of the horizontal positioning pin holes 6. The positions of the operation openings 102 correspond to the positions of the vertical positioning pin holes 9 and the first side mounting holes 101. A circular blocking piece is movably sleeved inside the first side mounting holes 101.

[0039] The long side 1 and the short side 2 of the side mold are fixed by inserting a connecting rod into the second side mounting hole 404, and are fixed in cooperation with the insertion and removal of the telescopic cushion plate 5, which is convenient for adjusting the fixing position. The overall mold design adopts the principle of "big set small", reducing the amount of molds used and lowering the investment in molds. Normally, the number of molds required is 13 sets for single-opening and 10 sets for crossover turnouts, a total of 23 sets of molds, and it is also impossible to take into account the production of left and right turnout sleepers. This time, 8 sets of single-opening molds are used and can also produce two products of left and right openings at the same time, and the number of crossover turnout molds is 3 sets. Different products are produced by moving the side mold and rotating the blocking piece according to product requirements. There are 8 sets of single-opening molds, and the compatible production blocks are: K1, K3 1 set, K2 1 set, K4, K5 1 set, K6, K7 1 set, K8, K9 1 set, K10, K11 1 set, K12 1 set. There are 3 sets of crossover turnouts, which are: LX1, LX2, LX3 left and right openings 1 set, LX4, LX5 1 set, K7, 1 set.

[0040] In another embodiment, as Figure 2 shown, mounting bolts 1501 are movably inserted into both ends of the reserved forming mold 15, and the specification dimensions of the reserved mounting holes 405 are adapted to the specification dimensions of the mounting bolts 1501.

[0041] During pouring, different reserved forming molds 15 are installed into the reserved installation holes 405 through installation bolts 1501, so as to fix the reserved forming molds 15 on the top of the bottom mold 4, and be used to leave an overall pre-installed customized groove on the concrete slab during pouring.

[0042] In another embodiment, as Figure 2 shown, the second side installation holes 404 are uniformly distributed in a rectangular linear array on the outer side of the top of the bottom mold 4. The telescopic backing plates 5 are uniformly distributed in a linear stack on the opposite sides of the long side 1 and the short side 2 of the side mold. The linear dimension of the row spacing of the second side installation holes 404 is adapted to the dimension of the telescopic backing plates 5. The specification dimension of the second side installation holes 404 is adapted to the specification dimension of the vertical positioning pin holes 9. The row spacing dimension of the second side installation holes 404 is smaller than the width dimension of the long side 1 of the side mold. The position of the horizontal positioning pin holes 6 corresponds to the position of the operation port 102. The horizontal positioning pin holes 6 penetrate through the long side 1 of the side mold and the telescopic backing plates 5 and extend into the interior of the short side 2 of the side mold. Bolts are inserted into the interior of the horizontal positioning pin holes 6.

[0043] The second side installation holes 404 provide fixed hole positions for the positions of the long side 1 and the short side 2 of the side mold. By inserting bolts into the interior of the vertical positioning pin holes 9 and then into the interior of the second side installation holes 404, the position of the long side 1 of the side mold is fixed. And by inserting bolts reserved in the interior of the short side 2 of the side mold into the interior of the second side installation holes 404, the short side 2 of the side mold is fixed. The dimension of the long side 1 of the side mold is larger than that of the second side installation holes 404, so that when the long side 1 of the side mold is moved, the second side installation holes 404 will not be exposed. Thus, the long side 1 of the side mold moves horizontally by the position of one telescopic backing plate 5 each time. By adjusting the taking out and putting in of the telescopic backing plates 5, the dimensions of the long side 1 and the short side 2 of the side mold are changed in cooperation, and then the size adjustment of the mold is changed. When fixing the long side 1, the short side 2 and the telescopic backing plates 5 of the side mold, bolts are inserted through the horizontal positioning pin holes 6 and penetrate through the long side 1, the short side 2 and the telescopic backing plates 5 of the side mold and reach the hollow position inside the short side 2 of the side mold, so as to fix the position, which is convenient for adjusting the size of the mold, mainly reflecting the quantity of the molds, reducing the investment and input of the molds. The main method adopted is "big sets small", using the moving side mold to replace different width requirements, and using the rotating blocking piece 10 to realize the position of the reserved nail hole distance of the embedded sleeve 12 for different requirements.

[0044] In another embodiment, as Figure 2 shown, the sinking docking holes 403 are linearly and uniformly distributed on the top of the bottom mold 4. The sinking docking holes 403 and the limit sliding plates 401 are linearly and staggeredly and uniformly distributed on the top of the long side 1 of the side mold. The specification dimension of the sinking docking holes 403 is adapted to the specification dimension of the rotating blocking piece 10. The specification dimension of the sinking waist groove holes 406 is adapted to the specification dimension of the waist groove limit piece 1001. The positioning bolts 11 movably penetrate through the rotating blocking piece 10 and extend to the bottom of the waist groove limit piece 1001.

[0045] The rotating plug 10, the sunken docking hole 403 and the sunken waist slot hole 406 are designed to be adjustable according to different nail hole distances, improving the versatility and flexibility of the mold. It is convenient for the rotating plug 10 to achieve the position of the nail hole distance reserved by the embedded sleeve 12 for different requirements. Moreover, the design of placing the rotating plug 10 and the waist slot limiting piece 1001 into the sunken docking hole 403 and the sunken waist slot hole 406 allows the rotating plug 10 and the waist slot limiting piece 1001 to be placed after rotating 180 degrees. This is convenient for adjusting the lateral dimension of the embedded sleeve 12 under the linear dimension of the sunken docking hole 403. When multiple molds are set, the straight slot distance of the waist slot limiting piece 1001 matches the size of the nail holes of the actual embedded sleeve 12, so as to reduce the number of molds. One mold can produce two types of embedded sleeves 12 with different distances, thus facilitating the adjustment of the nail hole positions.

[0046] In another embodiment, such as Figure 2As shown, the balanced vibration mechanism 13 includes eight mounting seats 1301 and a rotating motor 1314. At the bottom of each of the eight mounting seats 1301, a support column 1302 is fixedly installed. At the bottom of the support column 1302, a shock absorber 1303 is fixedly installed. At the bottom of the shock absorber 1303, a mounting base 1304 is fixedly installed. Inside the support column 1302, a support bearing 1316 is fixedly sleeved through a slot hole. Inside the support bearing 1316, a rotating rod 1305 is movably sleeved. Inside one end of the rotating rod 1305, a limit bolt 1315 is threadedly connected. At the end of the rotating rod 1305 away from the limit bolt 1315, a transmission disc 1308 is fixedly installed. On the outside of the transmission disc 1308, a number of leather flexible connections 1309 are fixedly installed. At the other end of the leather flexible connection 1309, a transmission shaft 1310 is fixedly installed. On the outside of the transmission shaft 1310, a transmission sprocket 1311 is fixedly sleeved. On the outside of the transmission sprocket 1311, a transmission chain 1312 is meshingly sleeved. On the outside of the transmission shaft 1310, a bearing support 1313 is movably sleeved. The output end of the rotating motor 1314 is drivingly connected to one of the transmission shafts 1310. Inside the mounting seat 1301, a number of connecting bolts 1307 are threadedly connected. On the outside of the rotating rod 1305, a number of eccentric wheels 1306 are fixedly sleeved. The specifications and dimensions of the mounting seat 1301 and the connecting bolt 1307 are adapted to the specifications and dimensions of the rubber buffer column plate position 8. The positions of the eight mounting seats 1301 correspond to the positions of the rubber buffer column plate position 8. The eccentric wheels 1306 are evenly distributed in a spiral pattern on the outside of the rotating rod 1305. The bottom vibration plate 14 is movably sleeved inside the bottom end of the bottom mold 4. On the top of the bottom vibration plate 14, a number of support columns 1404 are fixedly installed. At the bottom of the bottom mold 4, a number of connecting groove plates 1402 are rotatably connected by bolts. At one end of the connecting groove plate 1402 and inside the bottom vibration plate 14, mounting slot holes 1403 are provided. On the bottom of the bottom vibration plate 14, a number of vibrating sleeves 1401 are fixedly installed. The vibrating sleeves 1401 are evenly distributed linearly in a rectangular pattern on the bottom of the bottom vibration plate 14. The number and positions of the vibrating sleeves 1401 correspond to the number and positions of the eccentric wheels 1306. Inside the vibrating sleeve 1401, a hammering movable plug 1406 is movably sleeved. At the bottom of the hammering movable plug 1406, a connecting column 1407 is fixedly installed. On the outside of the connecting column 1407, a return spring 1405 is sleeved. The top end of the return spring 1405 is fixedly installed at the bottom of the hammering movable plug 1406. The bottom end of the return spring 1405 is fixedly installed at the bottom of the inner cavity of the vibrating sleeve 1401. The connecting column 1407 movably passes through and extends to the bottom of the vibrating sleeve 1401. Inside the bottom end of the connecting column 1407, a rolling bead 1408 is rotatably installed. The bottom of the rolling bead 1408 is in rolling contact with the outside of the eccentric wheel 1306. The support columns 1404 are evenly distributed linearly in a rectangular pattern on the top of the bottom vibration plate 14, and the top of the support columns 1404 is in contact with the bottom of the bottom mold 4. The connecting groove plates 1402 are evenly distributed linearly in a rectangular pattern on the bottom of the bottom mold 4.

[0047] When the balanced vibration mechanism 13 needs to vibrate, first, it is installed at the bottom of the rubber buffer column plate position 8 through the mounting seat 1301 and the connecting bolts 1307, and the bottom vibration plate 14 is placed inside the bottom end of the bottom mold 4. Then, the bottom vibration plate 14 is fixed to the bottom of the bottom mold 4 by inserting bolts through the internal mounting slot holes 1403. Next, the rotating motor 1314 is started to drive the transmission shaft 1310 to rotate. The transmission shaft 1310 drives different transmission shafts 1310 to rotate through the transmission sprockets 1311 and the transmission chain 1312. The rotating motor 1314 and the bearing support 1313 are fixed to the mounting platform by bolts. When the transmission shaft 1310 rotates, it drives the transmission disk 1308 through the leather flexible connection 1309, and then drives the rotating rod 1305 to rotate. The rotating rod 1305 rotates under the support of the support bearing 1316. The rotating rod 1305 drives the eccentric wheel 1306 to rotate, so as to contact the rolling beads 1408 through the eccentric extrusion of the eccentric wheel 1306, and then push the lifting of the connecting column 1407 through the eccentric action. Furthermore, the connecting column 1407 pushes the hammering movable plug 1406 to move upward. The elastic force of the return spring 1405 causes the rolling beads 1408 to maintain a relative position with the eccentric wheel 1306, and the bottom vibration plate 14 is knocked by the upward movement of the hammering movable plug 1406. Then, the vibration effect is transmitted to the bottom of the bottom mold 4 through the support column 1404. Under the connection of the rubber buffer column plate position 8 and the mounting seat 1301, the bottom mold 4 elastically stabilizes the vibration force through the support column 1302 and the shock absorber 1303. The corresponding linear uniform distribution of the eccentric wheel 1306 and the vibrating sleeve 1401 promotes the uniform vibration effect, which is convenient for vibrating the concrete inside the bottom mold 4, so as to ensure the uniformity of the concrete, reduce the air bubbles and ensure the quality of the concrete. The rolling beads 1408 can be replaced by a horizontally rotating bearing with the same width as the eccentric wheel 1306. The bearing is supported by the mounting slot in the connecting column 1407 and the fixed shaft in the middle, and is used for rolling contact with the outer side of the eccentric wheel 1306. It is convenient to change the rolling force into a vertical limiting effect when the eccentric wheel 1306 rotates to the maximum position, which is convenient for vibrating and knocking the bottom of the bottom mold 4, and thus indirectly promotes the uniformity of vibration.
