[0029] Please refer to Figure 1 , Figure 2 , Figure 5The present invention provides a wedge-shaped adjustable spacing separator. In order to solve the problem of inconvenience and time-consuming operation caused by the structural limitations of the separator when fixing the iron baffle used to separate the sleeper mold groove inside the steel mold groove during the current sleeper production casting process, a labor-saving, easy-to-operate adjustable spacing separator is designed, which can be adapted to different spacing widths according to needs. It specifically includes two tensioning plates 1, and the two tensioning plates 1 are connected by two sets of tensioning and limiting mechanisms 4. The two sets of tensioning and limiting mechanisms 4 are respectively located on both sides of the two tensioning plates 1. The two oppositely arranged tensioning plates 1 are connected from the two side positions while maintaining the spacing between the two tensioning plates 1. The spacing can also be freely moved within a certain range, providing the prerequisite basic structural conditions for spacing adjustment; the two There is a wedge block 2 between each end of the tensioning plate 1. The two wedge blocks 2 are designed to be relative to each other. The two wedge blocks 2 are slidably inserted between the two ends of the two tensioning plates 1 through a screwing assembly 3; the screwing assembly 3 is composed of a threaded rod 301 and a screwing nut 302. A threaded groove is provided at each end of the threaded rod 301. The two wedge blocks 2 are respectively sleeved on the outside of the two threaded grooves and form a threaded connection. In order to facilitate the installation and disassembly of the separator, its two threaded grooves are designed in reverse; the wedge block 2 is between the two ends of the two tensioning plates 1. When the screwing assembly 3 is rotated clockwise or counterclockwise, the wedge blocks 2 at the two ends of the tensioning plates 1 can be moved to relative or opposite positions, thereby realizing the opening and closing operation of the two tensioning plates 1 and achieving the purpose of adjusting the spacing between the separators.
[0030] See also Figure 1 、 Figure 2 、 Figure 3 In order to facilitate the two opening and closing plates 1 to be able to open and close synchronously when the two wedge blocks 2 move, so as to achieve the purpose of flexibly adjusting the spacing of the entire separator, the two opening and closing plates 1 are placed relative to each other. The opening and closing plates 1 are composed of a main body 101 and wedge surfaces 102 integrally formed at both ends of the main body 101 and designed with inclined surfaces; a wedge-shaped groove 104 is provided in the middle of the two inclined surfaces, and a straight groove 103 with a semicircular cross section is provided in the middle of the main body 101 for the threaded rod 301 to rotate, and the two ends of the straight groove 103 are respectively connected to the ends of the two wedge-shaped grooves 104.
[0031] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 In this embodiment, the wedge block 2 includes a wedge block 201, and mating surfaces 202 are symmetrically provided on both sides of one end of the wedge block 201 with the central axis of the wedge block 201 as the reference line. A positioning slider 203 is integrally formed in the middle position of each of the two mating surfaces 202; the two positioning sliders 203 are symmetrically designed; a threaded hole 204 is opened at the center position of the wedge block 201 to facilitate the threaded penetration of the threaded rod 301.
[0032] See alsoFigures 1-6 In this embodiment, in order to ensure that the wedge-shaped block 2 and the two pieces of the tensioning plate 1 can achieve effective wedge-shaped matching structure, and ensure that the wedge-shaped block 2 can always cooperate with the tensioning positioning mechanism to limit the positioning of the two pieces of the tensioning plate 1 during movement, the bottom of the wedge-shaped groove 104 and the side surface of the front end of the positioning sliding block 203 are designed as inclined surfaces, and the inclination angle is consistent with the angle of the wedge surface 102. The wedge-shaped groove 104 is designed as a dovetail groove, and when the fitting surface 202 and the wedge surface 102 slide and fit, the positioning sliding block 203 slides and inserts into the wedge-shaped groove 104. At the same time, in order to ensure that the wedge-shaped block 2 can smoothly move between the two pieces of the tensioning plate 1 under the driving of the screw assembly 3, the wedge-shaped block 2 and the tensioning plate 1 are both metal components, and the wedge-shaped groove 104 and the positioning sliding block 203 and the fitting surface 202 and the wedge surface 102 are all designed to be matched, and the surfaces of the fitting surface 202, the wedge surface 102, the positioning sliding block 203 and the groove wall of the wedge-shaped groove 104 are all designed as smooth mirror surfaces. Under the rotation of the threaded rod 301 of the screw assembly 3, the wedge-shaped block 2 slides between the wedge surfaces 102 at the ends of the two pieces of the tensioning plate 1. During the sliding process of the wedge-shaped block 2, the positioning sliding block 203 will synchronously slide in the wedge-shaped groove 104 following the movement of the wedge-shaped block 2, and pull or push the two pieces of the tensioning plate 1 to perform opening and closing actions.
[0033] Please refer to Figure 1 , Figure 2 In this embodiment, in order to improve the stability of the contact between the divider and the two iron baffle plates during use, and to improve the strength of the tensioning plate 1, anti-skid grooves are arranged on the outer side surfaces of the tensioning plate 1 in a cross design.
[0034] Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 In this embodiment, the screw nut 302 is welded at the end of the threaded rod 301. In order to expand the way of rotating the screw assembly 3 by the operator, prevent the outer side edges of the screw nut 302 from being slippery and unable to be smoothly rotated by the nut sleeve, a through pin hole 303 is horizontally arranged in the middle of the side surface of the screw nut 302. Once the outer side edges of the screw nut 302 are slippery, causing the nut sleeve to be unable to effectively engage and apply force to it, the operator only needs to find a steel rod with appropriate thickness to insert into the pin hole 303 to form a force point, so that the operator can also operate the divider by using the steel rod.
[0035] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6In the embodiment, two first hole positions 105 and one second hole position 106 are formed on both sides of the main plate body 101; in order to cooperate with the wedge-shaped blocks 2 and make the two sets of opening and closing plates 1 reach the parallel opening and closing relationship, each set of opening and closing limiting mechanism 4 is composed of two sliding groove plates 401 with sliding holes 404 formed in the middle and two support plates 402, and the middle part of the side of the sliding groove plate 401 close to the opening and closing plate 1 is provided with a gap sliding groove with the same length as the sliding hole 404;
[0036] The two sliding groove plates 401 in the same group are fixedly installed on the first hole positions 105 on the same side of the two opening and closing plates 1 through the fixing bolts 403, the two support plates 402 in the same group are designed in a cross shape, and the cross points of the two support plates 402 are rotationally connected through the support shafts 407, so as to form a scissors support structure; the tail ends of the two support plates 402 in the same group are rotationally installed on the second hole positions 106 on the same side of the two opening and closing plates 1 through the screw pins 405, in order to avoid that the scissors support structure interferes with the opening and closing action of the two opening and closing plates 1, the front ends of the two support plates 402 are slidably installed in the sliding holes 404 of the sliding groove plates 401 on the opening and closing plates 1 through the anti-disengagement pieces 408, and the same structure design is adopted on both sides of the two opening and closing plates 1 through the two sets of opening and closing limiting mechanisms 4, so that the opening and closing plate 1 is not only restricted by the positioning sliding block 203 and the wedge-shaped groove 104 in the wedge-shaped block 2, but also limited in opening and closing by the scissors support structure in the opening and closing limiting mechanism 4 during the opening and closing process, so as to realize the parallel opening and closing effect of the two opening and closing plates 1 under the action of the two wedge-shaped blocks 2.
[0037] Please refer to Figure 1 、 Figure 2 In the embodiment, in order to improve the stability of the scissors support structure in the opening and closing limiting mechanism 4, the limiting grooves 406 are arranged in the middle of the opposite sides of the two support plates 402, and the limiting grooves 406 on the two support plates 402 are movably buckled with each other.
[0038] In order to facilitate the maintenance of the opening and closing limiting mechanism 4 later, the anti-disengagement piece 408 is composed of a bolt with a nut and a flat nut, the bolt penetrates through the top of the support plate 402 and extends into the gap sliding groove at the bottom of the sliding groove plate 401 through the sliding hole 404, and the nut is located in the gap sliding groove at the bottom of the sliding groove plate 401 and is rotationally fixed at the front end of the screw rod of the bolt.
[0039] In use, the wedge-shaped blocks 2 at both ends of the two opening and closing plates should be kept in the initial position (and the two opening and closing plates 1 are in the closing state), when the iron baffle in the sleeper steel mold groove needs to be separated and fixed, the worker vertically inserts the separator in the initial state into the sleeper steel mold groove between the two baffle plates with the screw nut 302 upwards (as shown in FIG. 8), and then rotates the screw nut 302 to make the positioning sliding block 203 in the wedge-shaped block 2 slide along the wedge-shaped groove 104 to the position corresponding to the position of the iron baffle, so as to separate and fix the iron baffle in the sleeper steel mold groove. Figure 7The two ends of the threaded rod 301 with positive and reverse thread grooves are rotated by rotating the screw nut 302 through a sleeve tool or other auxiliary tools, and the wedge-shaped block 2 between the two ends of the two split plates 1 is synchronously closed in opposite directions, and the two split plates 1 are gradually separated by the cooperation of the wedge surface 102 and the matching surface 202 on the wedge-shaped block 2, until the two split plates 1 press the iron baffle in the track steel mold groove to play a separating and fastening role. When the iron baffle is removed and the separator is removed, as long as the rotating screw assembly 3 is reversely rotated to reduce the distance between the two split plates 1 and close them again, until the initial state is reached, the separator can be easily removed.

The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
