Description

Technical Field

[0001] The present invention relates to the technical field of track segments, in particular to a track concrete high-strength segment structure and processing equipment thereof. Background Art

[0002] In modern urban transportation, as ground space planning has become increasingly perfect, how to use underground space to improve the carrying capacity of the transportation system is an important development direction. The planning of urban subway tunnels has greatly alleviated the traffic pressure in the city. The construction technology of underground tunnels is mainly shield construction. During the shield construction process, the tunnel after the shield needs to be supported and installed by segments. At this stage, the tunnel segments are mainly made of concrete materials. In order to increase the support, steel bars are often embedded inside the tunnel segments.

[0003] At present, the production of tunnel segments mainly goes through the following production process. First, it is necessary to select suitable concrete, mix the concrete and test its performance. Then, it is necessary to make a suitable steel cage according to the shape of the segment, and then pour the concrete through the mold. After pouring and forming, the mold is demolded and cured. From the above process, the structural strength of the tunnel segment is mainly reflected in the high hardness, high bearing capacity and high toughness given by high-strength concrete and steel skeleton.

[0004] At present, the structural strength of the main body of the tunnel segments can be guaranteed by high-strength concrete and steel grids. However, the current segment connection positions are often connected by pre-embedded rods supplemented by sockets, mortise and tenon joints, etc. However, this connection method has a small stress surface at the socket position and the connection point is easily affected by problems such as water seepage, resulting in a reduction in the overall structural strength of the pipe ring formed by the tunnel segments.

[0005] In the current production process of tunnel segments, the steel skeleton often needs to be welded. Firstly, the welding connection method has too many connection points, and the structural strength of each weld point needs to be fully verified, which takes a long construction period. Secondly, the welding connection method has poor structural integrity, and the connection position of the weld point is prone to stress cracking, affecting the overall structural strength of the segment.

[0006] Moreover, in the current production process of tunnel segments, molds are mainly used to cast the tunnel segments. However, in order to avoid bubbles mixed into the concrete and uneven distribution of materials during casting, vibration is required during casting. However, the current vibration is mainly performed manually using a vibrator. However, manual vibration is labor-intensive and long-term labor affects the health of workers. Secondly, since manual operation is not precise, it brings about the problem of uneven distribution of the vibration effect, which easily leads to insufficient discharge of local bubbles. Furthermore, the current processing equipment still has the problem of low processing efficiency. Not only does vibration require manual assistance, but leveling is also performed manually, so the efficiency is low. In view of this, in-depth research on the above problems resulted in this case.

[0036] Beneficial effects

[0037] The present invention provides a high-strength concrete segment structure for a track and its processing equipment. It has the following beneficial effects: concrete segments are cast using a casting mold with an automatic roving vibration structure. The casting mold uses automatic vibration and scraping to improve the manufacturing efficiency and forming effect of the concrete segments. Furthermore, the high-strength concrete segments produced using this casting equipment use a steel frame as internal support. The steel frame uses a pair of prefabricated parallel positioning plates that are welded relative to each other to form an internal frame. The steel main structure is simple to produce and quickly welded, effectively reducing the welding workload, improving segment production efficiency, and ensuring the integrity and structural strength of the segments. It also has the following specific advantages:

[0038] 1. The steel frame uses a pair of parallel arc-shaped positioning plates to form the upper and lower welded bodies of the steel frame. When used, the steel frame is formed by adding transverse ribs, reinforcement components and reinforcement ribs to improve the overall structural strength of the steel frame. The pair of positioning plates can be integrally formed, which not only reduces the workload during the welding process, but also makes the integrally formed structure stronger.

[0039] 2. Matching connection components are set on both sides of the steel frame. The connection components are composed of side reinforcement ribs and connecting side plates. The connection components further expand the structural composition of the steel frame, improve the bonding effect with the concrete pipe body, and cooperate with the embedded components to play a role in strengthening the connection when connecting the pipe segments;

[0040] 3. Socket wings are provided on both sides of the concrete segment body. The wings match the socket structure and play a guiding and connecting role. The wings are integrally formed with the concrete segment body, which is simple to manufacture. The wings are large, long, single trapezoidal plate structures. The joint contact area at the segment joint is larger, ensuring the stability of the segment connection. The side reinforcement ribs of the inner lining also play a reinforcing role.

[0041] 4. The processing equipment for high-strength concrete segments of rail tracks uses an automated positioning guide frame to control the movement of the casting scraper. The casting scraper moves along with the positioning guide frame and moves according to the curvature of the casting shell, making it convenient and quick to perform the scraping operation on the main body of the concrete segment.

[0042] 5. The processing equipment is also equipped with an automatic reciprocating vibration device. The vibration device moves evenly at the bottom of the casting shell. Through the vibration effect of the vibration structure, it automatically vibrates the concrete, making the vibration more uniform and comprehensive, avoiding gaps and bubbles in the pipe segment, and ensuring the structural strength of the pipe segment.

[0056] 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.

[0057] See also Figure 1-12The present invention provides an implementation scheme: in the application process of track concrete segments, the segments are mainly processed by pouring, and the structural strength of the segments is improved by cooperating with steel skeletons. However, the current track concrete segments have the following problems: first, the transverse connection structure of the segments is mainly connected by socket or riveting, and the connection of the segments is not sufficient, which easily leads to insufficient structural strength of the segment track; second, the steel skeleton of the segments has many welding points and requires auxiliary equipment for alignment and fixation, which is inconvenient to operate; third, manual auxiliary vibration is required during pouring. Since the vibration range is limited and the vibration rate is low, the operation is inconvenient and bubbles are easily retained, and manual scraping is required, resulting in low production efficiency and affecting the quality of the segments.

[0058] Example 1: According to the instructions attached Figure 1 -Attached Figure 6 It can be seen that in response to the above problems, the present application discloses a railway concrete high-strength pipe segment structure, including a concrete pipe segment body 1 and a steel frame 2, the steel frame 2 serving as the skeleton of the concrete pipe segment body 1, the concrete pipe segment body 1 being a main structure made of concrete pouring, the concrete pipe segment body 1 being wrapped around the steel frame 2, the concrete pipe segment body 1 being an arc-missing annular plate of a concrete structure, and when in use, multiple concrete pipe segment bodies 1 are enclosed to form a tubular body, mutually matching connecting components 27 are provided on both sides of the concrete pipe segment body 1, and the connecting components 27 can play a radial connection role of adjacent concrete pipe segment bodies 1, and then the steel frame 2 is an arched frame, the arched structure of the steel frame 2 matches the shape of the concrete pipe segment body 1, and plays a reinforcing role on the concrete pipe segment body 1, and after pouring, the concrete pipe segment body 1 is wrapped around the steel frame 2, the compressive strength of the concrete used for the concrete pipe segment body 1 is at least 30MPa, and the concrete waterproof grade of the concrete pipe segment body 1 is not less than the anti-seepage grade of P10, and the concrete and steel selection of the concrete pipe segment body 1 need to meet the strength and waterproof requirements;

[0059] Furthermore, according to the instructions Figure 1 -Attached Figure 6 It can be seen that the steel frame 2 includes a pair of positioning plates 21, which are arranged opposite to each other. Four positioning sleeves 22 are provided on one positioning plate 21, and four positioning rods 23 are provided on the other positioning plate 21. The positioning rods 23 are assembled in the positioning sleeves 22;

[0060] In the specific implementation process, the four positioning sleeves 22 on one positioning plate 21 correspond to the four positioning rods 23 on the other positioning plate 21. When welding, the positioning plate 21 provided with the positioning rods 23 is first aligned with the positioning sleeves 22 on the other positioning plate 21, so that the positioning rods 23 are inserted into the positioning sleeves 22, thereby fixing the pair of positioning plates 21, facilitating the welding of the steel frame 2 and improving the convenience of welding.

[0061] Furthermore, a pair of positioning plates 21 are a pair of arc-shaped plates, and the curvatures of the pair of positioning plates 21 match each other. A pair of steel bar structure bodies are formed on the radially outer and inner sides of the pipe segment of the reinforcement frame 2 through the relative arrangement of the pair of positioning plates 21. A plurality of pairs of transverse ribs 24 are welded on opposite sides of the pair of positioning plates 21 to strengthen the structure of the positioning plates 21. Furthermore, a plurality of pairs of transverse ribs 24 are evenly distributed on the positioning plates 21 in a fan shape and welded to the positioning plates 21. A plurality of casting channels 29 are provided at intervals corresponding to the plurality of transverse ribs 24 on the positioning plates 21. The casting channels 29 are used for passing through during the casting and forming process of the concrete pipe segment body 1, and reduce the structural weight of the positioning plates 21, so that the combination of the reinforcement frame 2 and the pipe segment is more complete. Moreover, the positioning plates 21 are an integrated structure, which is convenient for manufacturing during production.

[0062] The reinforcement between the pair of positioning plates 21 cannot effectively play a supporting role by relying solely on the cooperation of the positioning sleeves 22 and the positioning rods 23, and the degree of integration with the concrete segment body 1 is insufficient. Therefore, a plurality of reinforcing ribs 25 are provided between the pair of positioning plates 21. The plurality of reinforcing ribs 25 are arranged in a matrix between the pair of positioning plates 21, and the ends of the plurality of reinforcing ribs 25 are welded to the plurality of transverse ribs 24 of the pair of positioning plates 21.

[0063] Furthermore, a number of reinforcing components 26 are evenly arranged along the axial direction on the transverse ribs 24, and the ends of the reinforcing components 26 are connected to the ends of the reinforcing ribs 25. The reinforcing components 26 are welded to the positioning plate 21 and the ends of the reinforcing ribs 25 to improve the connection effect between the reinforcing ribs 25 and the positioning plate 21, and the reinforcing components 26 also play a radial reinforcement role on the positioning plate 21.

[0064] According to the instruction manual Figure 1 -Attached Figure 6 As can be seen, the connection assembly 27 includes a socket wing 11. The socket wing 11 extends from one side of the concrete segment body 1. The other side of the concrete segment body 1 is recessed with a socket 12. The structures of the socket wing 11 and the socket 12 match. The socket wing 11 is provided with a side reinforcement rib 271 that is welded to one side of the positioning plate 21.

[0065] In the specific implementation process, the cross section of the socket side wing 11 is a trapezoidal structure, the cross section of the side reinforcement rib 271 is a trapezoidal cavity structure, one end of the side reinforcement rib 271 is welded to the side of a pair of positioning plates 21, so that the side reinforcement rib 271 is connected to the positioning plate 21, and the side reinforcement rib 271 is used to strengthen the socket side wing 11, thereby improving the integrity and bonding of the socket side wing 11 and the concrete pipe body 1. The socket slot 12 is a through groove that matches the socket side wing 11. When in use, the socket side wing 11 is inserted from one side of the socket slot 12. Since the shape of the socket slot 12 matches that of the socket side wing 11, it plays a guiding role in the installation of the concrete pipe segment main body 1, and a connecting side plate 272 with a shape corresponding to the side reinforcing rib 271 is buried on the inner side of the socket slot 12. A number of through holes are opened on the connecting side plate 272, and a number of through sleeves 273 extend from both sides of the through holes. The number of through sleeves 273 passes through both sides of the socket slot 12. The connecting side plate 272 arranged on the inner side of the socket slot 12 supports and strengthens the socket slot 12 and serves as an anchor point when connecting the pipe segments.

[0066] According to the instruction manual Figure 1 -Attached Figure 6 It can be seen that the above-mentioned concrete pipe segment body 1 is pre-embedded with an embedded component 28, which is connected to the steel frame 2 to play a connecting and locking role with other pipe segment structures. Specifically, the embedded component 28 is set on the side reinforcement ribs 271 and the connecting side plates 272. When a pair of adjacent concrete pipe segment bodies 1 are plugged into each other, the socket wing 11 of one concrete pipe segment body 1 is inserted into the socket 12 of the other concrete pipe segment body 1. When the socket wing 11 on one concrete pipe segment body 1 is inserted into the socket 12, the large-volume trapezoidal block structure of the single socket wing 11 effectively increases the connection contact area and bearing capacity between the socket wing 11 and the socket 12. The embedded side reinforcement ribs 271 and the connecting side plates 272 play a further strengthening role.

[0067] Specifically, the embedded component 28 includes a plurality of threaded seats 281. A plurality of threaded seats 281 are arranged in a linear array on one side of the side reinforcement rib 271. A plurality of embedded pipes 282 are threadedly connected to the plurality of threaded seats 281. The positions of the plurality of embedded pipes 282 correspond to the positions of the plurality of through sleeves 273 and pass through the socket slot 12.

[0068] During the specific implementation process, the embedded component 28 also includes a number of fastening bolts 283. When the socket side wing 11 is connected to the socket socket 12, the fastening bolts 283 pass through the sleeve 273 and are threadedly connected to the embedded pipe 282, so that the fastening bolts 283 are pulled back through the sleeve 273 and are threadedly connected to the embedded pipe 282, thereby strengthening the connection between the socket socket 12 and the socket side wing 11, and during pouring, they are connected to the anchor point in the pouring mold through the embedded pipe 282, thereby fixing the steel frame 2.

[0069] Furthermore, the reinforcing component 26 includes a reverse pull ring 261, which is wrapped around the outside of the transverse rib 24 and welded to the positioning plate 21 at both ends. The middle section of the reverse pull ring 261 is welded to the side of the reinforcing rib 25. The reverse pull ring 261 is a semi-annular reverse buckle structure that wraps the outside of the transverse rib 24, thereby strengthening the fixed connection between the positioning plate 21 and the reinforcing rib 25.

[0070] Example 2: According to the instructions attached Figure 7 -Attached Figure 12 It can be seen that in order to cooperate with the above-mentioned pipe segment processing, the present application also discloses a processing equipment for high-strength rail concrete pipe segments, including a casting platform 3 and a mold base 4. The casting platform 3 is arranged above the mold base 4, and a pair of guide rails are provided at the bottom of the mold base 4. During the casting process of the concrete pipe segment body 1, the casting components are integrated using the casting platform 3, and a casting shell 5 is provided on the mold base 4. The casting shell 5 is supported by the mold base 4, and the mold base 4 can be transported and moved between different processing stations using a pair of guide rails, so as to facilitate the casting and molding of the concrete pipe segment body 1.

[0071] A rotating seat 41 is provided on one side of the casting shell 5, and a mold clamp 6 is assembled on the rotating seat 41. The rotating seat 41 is hingedly connected to the mold clamp 6. The inner arc of the mold clamp 6 matches the outer arc of the casting shell 5. The casting shell 5 is used as a carrying container for casting the concrete pipe segment body 1 through the casting inlet 61. The mold clamp 6 is used to close the top surface opening of the casting shell 5. The sealing effect of the casting shell 5 is achieved by controlling the switch of the mold clamp 6. This facilitates the shaping of the pipeline during casting and facilitates maintenance and other operations after the casting is completed. The casting shell 5 is an arc-shaped groove with an opening at the top. The top of the mold clamp 6 is provided with a casting inlet 61, which corresponds to the casting platform 3, so that the concrete can be accurately dropped from the casting inlet 61 into the casting shell 5 during the casting process.

[0072] According to the instruction manual Figure 7 -Attached Figure 12 As can be seen, the pouring platform 3 is provided with a pouring controller, which includes a pouring bucket 31. A pouring pipe 32 extends from the bottom of the pouring bucket 31. A control gate 33 is provided on the pouring pipe 32. The poured concrete is transported by the pouring bucket 31 and the pouring bucket 31 plays a diversion role, pouring the concrete from the pouring pipe 32 toward the pouring inlet 61. The pouring pipe 32 is provided with a control gate 33. The control gate 33 can be used to control the opening and closing of the pouring pipe 32, thereby facilitating the control of pouring.

[0073] Moreover, a device for scraping the top surface of the segment is integrated on the casting platform 3. A positioning guide frame 8 is provided on the casting platform 3. The positioning guide frame 8 is connected to the casting platform 3 by a track structure perpendicular to the horizontal. The positioning guide frame 8 is raised and lowered by the track structure. During casting, the height of the positioning guide frame 8 is controlled to avoid affecting the opening and closing of the mold clamping device 6 of the casting mold. A casting scraper 9 is provided on the positioning guide frame 8. The casting scraper 9 can move along the positioning guide frame 8. Through the action of the positioning guide frame 8, the cast concrete segment body 1 can be scraped and leveled.

[0074] In order to avoid bubbles in the concrete during the pouring process, a vibrating structure 7 is provided on the mold base 4. The vibrating structure 7 is used to vibrate the concrete poured in the pouring shell 5. The vibrating structure 7 adopts automatic control and uniform reciprocating motion to evenly cover the entire range of the pouring shell 5 for vibrating. During pouring, the vibrating effect of the vibrating structure 7 plays a role in expelling bubbles from the poured concrete structure.

[0075] The casting shell 5 is provided with a steel bar connection anchor point for connecting to the steel bar frame 2 of the concrete segment body 1. The steel bar connection anchor point can be connected to at least the through sleeve 273 and the embedded pipe 282 on the steel bar frame 2, thereby fixing the steel bar frame 2 and preventing the steel bar frame 2 from moving during casting, which would affect the overall structure of the concrete segment body 1.

[0076] According to the instruction manual Figure 7 -Attached Figure 12 It can be seen that the positioning guide frame 8 includes a fixed frame 81, which is connected to the casting platform 3. The fixed frame 81 serves as a supporting base. Two pairs of lifting rails 82 perpendicular to the horizontal are provided on both sides of the fixed frame 81. The two pairs of lifting rails 82 are connected to the guide frame 83. The lifting rails 82 serve as a connection between the guide frame 83 and the fixed frame 81. When the guide frame 83 is raised or lowered, the lifting rails 82 serve as a guide and limiter for the guide frame 83 to prevent the guide frame 83 from shaking during the raising or lowering process.

[0077] According to the instruction manual Figure 7 -Attached Figure 12It can be seen that a horizontal screw module 84 is provided on the guide frame 83, and a pair of guide seats 85 are provided on the pair of screw modules 84. The horizontal movement of the pair of guide seats 85 can be controlled by the pair of horizontal screw modules 84. A pair of lifting sleeves 91 are provided on the pair of guide seats 85. The pair of guide seats 85 can drive the pair of lifting sleeves 91 to move. The movement range of the pair of guide seats 85 covers the upper part of the entire casting shell 5. A pair of lifting rods 92 are inserted in the pair of lifting sleeves 91. The bottom of the pair of lifting rods 92 is connected to a guide wheel 93. A pair of arc grooves 94 are provided on both sides of the casting shell 5 corresponding to the pair of guide wheels 93. A scraper 95 is connected between the pair of lifting rods 92. The scraper 95 is parallel to the curvature of the casting shell 5. The bottom end of the scraper 95 penetrates 5-10 mm below the top surface of the casting shell 5. When scraping, the mold clamping device 6 is opened and the pair of lifting rods 92 are connected. The pair of lifting rods 92 are connected by a cross bar, and a pair of lifting rods 92 move horizontally with a pair of lifting sleeves 91, and the pair of lifting rods 92 always have a tendency to move downward under the action of the lifting springs in the lifting sleeves 91. When scraping, a pair of guide wheels 93 at the bottom ends of the pair of lifting rods 92 contact a pair of arc grooves 94. The pair of arc grooves 94 guide the pair of guide wheels 93, so that the pair of guide wheels 93 can move horizontally and match the height change of the casting shell 5, so that the pair of lifting rods 92 can be lifted and lowered in the lifting sleeves 91, and then the scraper 95 between the pair of lifting rods 92 moves synchronously with the pair of lifting rods 92. Since the guide wheels 93 can move with the curvature of the casting shell 5, the scraper 95 is always kept at a fixed height from the top surface of the casting shell 5, and the scraper 95 passes through the top surface of the concrete pipe segment body 1 to complete the scraping construction of the top surface of the concrete pipe segment body 1.

[0078] According to the instruction manual Figure 7 -Attached Figure 12 It can be seen that a mounting groove is provided on the mold base 4, and the mounting groove matches the structure of the casting shell 5. A number of fixing holes are provided on the mounting groove, and a number of fixing rods are provided on the bottom surface of the casting shell 5. A number of fixing rods pass through a number of fixing holes, and the bottom ends of the number of fixing rods are provided with horizontal detachable bolts connected to the mold base 4. In the specific implementation process, the mounting groove serves as a space for installing equipment in the mold base 4. Through the corresponding action of the fixing rods and the fixing holes, it plays a supporting and limiting role when the casting shell 5 is placed in the mold base 4.

[0079] Furthermore, a plurality of pairs of reinforcing sealers are symmetrically provided on both sides of the mold base 4, and the plurality of pairs of reinforcing sealers are connected to both sides of the mold clamp 6 by tension;

[0080] According to the instruction manual Figure 7 -Attached Figure 12It can be seen that the above-mentioned reinforcement sealer includes a reinforcement groove 42, which is provided on a side wall of the mold base 4. A threaded hole is opened on the reinforcement groove 42, and an adjusting bolt 43 is threadedly connected to the threaded hole. The end of the adjusting bolt 43 is connected to a clamping block 44 through a chain. A plurality of pairs of clamping grooves 62 are symmetrically provided on both sides of the mold clamp 6. After the clamping blocks 44 at corresponding positions are placed in the clamping grooves 62, the clamping blocks 44 are reversely pulled and locked by the adjusting bolt 43.

[0081] During the specific implementation process, the threaded hole on the reinforcement groove 42 is threadedly connected with the adjusting bolt 43, so that the adjusting bolt 43 can move linearly in the reinforcement groove 42. When the mold clamper 6 is closed, the clamping block 44 is clamped into the clamping groove 62, and then the adjusting bolt 43 is rotated to engage with the threaded hole, so that the adjusting bolt 43 moves linearly to tighten the chain, and the clamping block 44 is fully matched with the clamping groove 62, so that the mold clamper 6 is buckled on the casting shell 5, ensuring that the mold clamper 6 is closed more tightly.

[0082] According to the instruction manual Figure 7 -Attached Figure 12 It can be seen that the above-mentioned vibration structure 7 includes a vibration chute 71, a vibration chute 71 is provided on the mold base 4 along the curvature of the casting shell 5, a sliding arc plate 72 is provided on the vibration chute 71, and the sliding arc plate 72 is assembled in the vibration chute 71. A vibration guide control component 73 is provided in the mold base 4 and is connected to the sliding arc plate 72. At least three vibrators 74 are provided on the sliding arc plate 72 corresponding to the center line of the casting shell 5 and on both sides.

[0083] During the specific implementation process, the vibration chute 71 matches the curvature of the casting shell 5, and the sliding arc plate 72 is assembled in the vibration chute 71. The sliding arc plate 72 can be controlled to move by using the vibration guide control component 73, so that the sliding arc plate 72 drives the vibrator 74 to move. The movement range of the vibrator 74 covers most of the bottom surface of the casting shell 5, and the vibrating end of the vibrator 74 is arranged in contact with the bottom surface of the casting shell 5. During pouring, the vibrator 74 is driven by the sliding arc plate 72 to move at a uniform speed within the coverage range of the bottom surface of the casting shell 5. Since the vibrator 74 contacts the bottom surface of the casting shell 5, the vibration effect of the vibrator 74 is transmitted to the casting shell 5, and the vibration is transmitted to the concrete, causing the concrete to vibrate slightly, thereby expelling the bubbles therein and making the concrete more evenly distributed in the casting shell 5.

[0084] Further, according to the instructions Figure 7 -Attached Figure 12As can be seen, the vibrating guide control assembly 73 includes an arcuate guide rail 731 disposed on the inner side of the mold base 4. A power control board 732 extends from the bottom surface of the sliding arc plate 72. A guide control motor 733 is disposed on the power control board 732. The driving end of the guide control motor 733 is connected to a guide gear set 734. The arcuate guide rail 731 is provided with an arcuate tooth groove 735 corresponding to the guide gear set 734, and the arcuate tooth groove 735 meshes with the guide gear set 734.

[0085] During the specific implementation process, the curvature of the arc guide rail 731 matches the curvature of the casting shell 5, and the power control board 732 is used to install the guide control motor 733. The guide control motor 733 drives the guide gear group 734 to move, and then the guide gear group 734 engages with the arc tooth groove 735. Under the reverse thrust of the arc tooth groove 735, the sliding arc plate 72 is pushed to move. Due to the limitation of the vibrating slide groove 71, the sliding arc plate 72 can only move along a fixed path. By controlling the forward and reverse rotation of the guide control motor 733, the movement direction of the sliding arc plate 72 is controlled, and the sliding arc plate 72 drives the vibrator 74 thereon to move at a uniform speed.
