Description

Technical Field

[0001] The invention relates to the technical field of railway track laying equipment, in particular to a complete set of high-precision self-compacting concrete pouring equipment. Background Art

[0002] High-speed rail tracks are usually ballastless tracks, which are mainly based on concrete, asphalt mixtures, etc. instead of the loose gravel roadbed. The track structure has strong integrity and high stability. The structure of ballastless track is mainly composed of a base made of reinforced concrete, an isolation layer made of geotextile, a filling layer made of self-compacting concrete pouring, and a track slab at the top. In order to prevent the track slab from deflecting, floating and sliding on the base after the self-compacting concrete is poured, a corresponding set of high-precision self-compacting concrete pouring equipment is usually set up during the construction process for auxiliary shaping; For example, the existing Chinese patent publication number is: CN201738200U, and the name of the patent is "A ballastless track slab laying limit device". The patent "first drills anchor holes on the base, then glues the anchors with glue, fills the anchor holes with glue, and slowly screws the anchors in at a uniform speed to form a full thread on the glue. After reaching the strength, the anchors are fixed and bonded to the concrete layer of the base. At this time, adjust the position and height of the support screw on the track slab, install the floating channel steel, tighten the floating bolts, make the floating channel steel close to the surface of the track slab, and the anti-floating device can work normally to prevent the track slab from floating." The existing self-compacting concrete high-precision pouring equipment mainly tightens the floating bolts to make the floating channel steel close to the surface of the track plate when compacting and shaping the track plate. A torque wrench is often used to tighten the floating bolts to make the pressure values ​​of various compressed positions of the track plate tend to be consistent. However, the above scheme has the disadvantage that since most of the screw rods are exposed to the external environment, and the torque wrench indirectly judges the pressure of the track plate by the resistance of the bolt rotation, then when the screw rods are rusted and damaged, the resistance to rotation of the bolts on different screw rods is likely to be different, and then the pressure value judgment of each compressed position of the track plate layer is biased, resulting in a large difference between the pressure values ​​of various parts of the track plate layer.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] See also Figure 1-11 The embodiment of the present invention provides a self-compacting concrete high-precision pouring equipment set, comprising a base platform 1 and steel bars 2 extending from two sides of the base platform 1, and a clamping mechanism that can be connected to the steel bars 2 is provided on the top of the base platform 1, and the clamping mechanism includes: The compression beam assembly 3 includes a cross beam unit 3.1, and both ends of the cross beam unit 3.1 are equipped with a pulling unit 3.2 that can be connected to the reinforcement rod 2; The side fixing assembly 4 comprises a side limit column 4.1 located at one side of each cross beam unit 3.1, and a compression limit unit 4.2 is installed on each side limit column 4.1, and the compression limit unit 4.2 is transmission-connected to the cross beam unit 3.1 through a transmission mechanism 4.3; The tightening assembly 5 comprises two groups of lever units 5.1 movably mounted on the cross beam unit 3.1. One end of each lever unit 5.1 is connected to the pulling unit 3.2 through a slider unit 5.2, and the other end of each lever unit 5.1 is connected to the cross beam unit 3.1 through a force applying unit 5.3. When the force applying unit 5.3 is in a downward pressing state, the compression beam assembly 3 and the side fixing assembly 4 are both in a tightening state. It should be noted that the base platform 1 is a rectangular platform made of reinforced concrete. Both sides of the base platform 1 are preset with horizontally extending steel bars 2. A track slab 7 is arranged above the base platform 1, and the track slab 7 is also a plate-shaped structure formed by prefabricated and solidified concrete. There is a accommodating space between the top of the base platform 1 and the track slab 7. A pouring port is reserved at the top of the track slab 7. A protective frame 16 is installed on the circumference of the track slab 7 to block the side of the accommodating space, so that the inner wall surface of the protective frame 16, the bottom surface of the track slab 7 and the top surface of the base platform 1 constitute a containing space for accommodating self-compacting concrete. When the self-compacting concrete in the containing space solidifies, a filling layer of the ballastless track is formed. In order to prevent the track slab 7 from deflecting, floating and sliding on the base platform 1 due to the force of the self-compacting concrete after the self-compacting concrete is poured, a corresponding high-precision pouring set of self-compacting concrete equipment is usually provided during the construction process for auxiliary shaping. Specifically, the technical solution adopted in the present invention is that a cross beam unit 3.1 is arranged above the track slab 7, the bottom of the cross beam unit 3.1 is in contact with the top surface of the track slab 7, the length direction line of the cross beam unit 3.1 is parallel to the direction line of the steel bar 2, and both ends of the cross beam unit 3.1 are connected to the steel bar 2 through a pulling unit 3.2. At this time, the track slab 7 is located between the cross beam unit 3.1 and the base 1 in the vertical direction, and the side limit column 4.1 fixed to the cross beam unit 3.1 is located on the side of the track slab 7. The compression unit 4.2 is also fitted with the side of the track slab 7. When the force-applying unit 5.3 is in the downward pressure state, the crossbeam unit 3.1 applies pressure to the track slab 7 toward the base platform 1, and the compression unit 4.2 also applies a pushing force to the side of the track slab 7. At this time, the track slab 7 is clamped both vertically and horizontally, and the compression beam assembly 3 and the side fixing assembly 4 are in a tightening state, thereby ensuring that the position of the track slab 7 is fixed, and avoiding the track slab 7 from being deflected, floating and sliding on the base platform 1 due to the force of the self-compacting concrete; On the other hand, by setting a clamping mechanism consisting of a pressure beam assembly, a side fixing assembly and a tightening assembly, when the force-applying unit on the tightening assembly is in a downward pressure state, the two groups of lever units simultaneously transmit pressure to the corresponding pressure beam assembly and the side fixing assembly, so that the pressure beam assembly and the side fixing assembly are both in a clamping state at the same time, thereby making the pressure on both sides of the track plate on the base platform the same time and the pressure values ​​are consistent, and at the same time avoiding the situation in the prior art where the pressure value is inaccurately measured due to the rust of the screw, which is beneficial to reducing the difference in pressure between various parts of the track plate layer, so that the pressure on various parts of the track plate layer is in a balanced state, and the contact area with the track plate layer 7 is increased, and the pressure state on both sides of the track plate layer 7 can be controlled by one force-applying unit 5.3, which is simple to operate and also beneficial to improving construction efficiency.

[0020] Another embodiment provided by the present invention, the beam unit 3.1 includes a beam column 3.11 whose length direction line is parallel to the axial line of the steel bar 2, and a transverse accommodating cavity 3.12 is provided in the beam column 3.11, and the transverse accommodating cavity 3.12 is a cavity constructed of a rectangular column. The cross section of the beam column 3.11 is rectangular, and the bottom surface of the beam column 3.11 is in contact with the top surface of the track slab 7, thereby increasing the force-bearing area. Preferably, a reinforcing rib plate is provided in the transverse accommodating cavity 3.12, thereby increasing the bending strength of the beam column 3.11. In actual use, the beam column 3.11 is lifted and placed on the track slab 7, and both ends of the beam column 3.11 extend out in the width direction of the track slab 7, and the length direction line of the beam column 3.11 is parallel to the axial line of the steel bar 2, and the length direction line of the beam column 3.11 is parallel to the horizontal plane.

[0021] In another embodiment provided by the present invention, the pulling unit 3.2 includes a gear rod 3.21 that vertically movably penetrates the cross beam 3.11. The gear rod 3.21 is a cylindrical rod. Both sides of the gear rod 3.21 are provided with a flat portion 15. The axis of the gear rod 3.21 is perpendicular to the axis of the cross beam 3.11. The bottom end of the gear rod 3.21 is provided with a slot 3.22 that can be adapted to the steel bar 2. A stopper 3.23 is movably hinged on the notch of the slot 3.22. The stopper 3.23 has a blocking state and an open state on the slot 3.22. In the blocking state, the stopper 3.23 can block the steel bar 2 from moving along the gear rod 3. 21 axial direction from the notch of the slot 3.22, the stopper 3.23 in the open state can allow the steel bar 2 to be separated from the notch of the slot 3.22 along the axial direction of the toothed bar 3.21, preferably, a convex stopper 8 is fixed on the inner wall surface of the notch end of the slot 3.22, the convex stopper 8 can prevent the stopper 3.23 from being separated from the slot 3.22, when the convex stopper 8 is in contact with the stopper 3.23, the stopper 3.23 is in a state of blocking the notch of the slot 3.22, when the convex stopper 8 is separated from the stopper 3.23, and the convex stopper 8 is located in the notch of the slot 3.22, the convex stopper 8 is in an open state; When the cross beam 3.11 is placed on the track slab 7, the toothed rod 3.21 is synchronously lowered with the cross beam 3.11, and the bottom end of the toothed rod 3.21 is also close to the reinforcing rod 2. When the reinforcing rod 2 is engaged with the slot 3.22, the stopper 3.23 is subjected to the force of the reinforcing rod 2 and switches from the blocked state to the open state, so that the reinforcing rod 2 enters from the slot of the slot 3.22. When the reinforcing rod 2 contacts the bottom of the slot 3.22, the stopper 3.23 is restored from the open state to the blocked state under the action of gravity. As the cross beam 3.11 continues to move downward, the toothed rod 3.21 cannot continue to descend under the support of the reinforcing rod 2, so that the toothed rod 3.21 moves upward with the cross beam 3.11 as a reference until the cross beam 3.11 contacts the track slab 7. At this time, the vertical spacing between the cross beam 3.11 and the reinforcing rod 2 is determined.

[0022] In another embodiment provided by the present invention, the top of the side limit column 4.1 is vertically fixed to the bottom of the cross beam column 3.11, and a vertical accommodating cavity 4.11 is provided in the side limit column 4.1, and the vertical accommodating cavity 4.11 is a cylindrical cavity, wherein the compression unit 4.2 includes a round-mouth unit 4.21 provided on the side wall of the vertical accommodating cavity 4.11, the round-mouth unit 4.21 faces the direction where the track slab layer 7 is located, and an internally threaded tube 4.22 extending into the vertical accommodating cavity 4.11 is movably inserted in the round-mouth unit 4.21, and the internally threaded tube 4.22 is inserted into the vertical accommodating cavity 4.11. The axis line of the internal threaded tube 4.22 is parallel to the length direction line of the cross beam column 3.11, the axis line of the internal threaded tube 4.22 is perpendicular to the axis line of the side limit column 4.1, the inner end of the internal threaded tube 4.22 is spirally inserted with a threaded rod 4.23, one end of the threaded rod 4.23 extends out of the vertical accommodating cavity 4.11, and a first axis limit unit 6 is provided between the internal threaded tube 4.22 and the round mouth unit 4.21. The first axis limit unit 6 can limit the axial rotation of the internal threaded tube 4.22 in the round mouth unit 4.21 when it is extended; In actual use, when the first axis limit unit 6 is in the extended state, if the gear rod 3.21 moves upward with the cross beam column 3.11 as a reference, the threaded rod 4.23 rotates forwardly under the action of the transmission mechanism 4.3. At this time, the internal threaded tube 4.22 receives the spiral drive of the threaded rod 4.23 and moves toward the track plate layer 7. When the extended end of the internal threaded tube 4.22 contacts the track plate layer 7, the first axis limit unit 6 switches from the extended state to the retracted state, so that the first axis limit unit 6 no longer restricts the axial rotation of the internal threaded tube 4.22 in the round mouth unit 4.21. Then, when the threaded rod 4.23 continues to rotate forward, the internal threaded tube 4.22 rotates coaxially with the threaded rod 4.23. At this time, the extended end of the internal threaded tube 4.22 fits against the side of the track plate layer 7, that is, the compression unit 4.2 fits against the side of the track plate layer 7.

[0023] In another embodiment of the present invention, the first axis limit unit 6 includes a plurality of plug-in ports 6.1 provided at the insertion end of the internal threaded tube 4.22, the length direction line of the plug-in port 6.1 is parallel to the axis center line of the internal threaded tube 4.22, and a long groove 6.5 corresponding to each plug-in port 6.1 is provided on the side of the internal threaded tube 4.22, and a plurality of connecting ports 6.2 connected to the plug-in port 6.1 are provided at the bottom of each long groove 6.5, and each plug-in port 6.1 is movably plugged with a bar 6.3, and one end of each bar 6.3 is The bar 6.3 extends out of the plug-in port 6.1, and one end of the bar 6.3 extending out of the plug-in port 6.1 is a rough end. The other end of each bar 6.3 is connected to the bottom of the plug-in port 6.1 through a spring 6.7. Each connecting port 6.2 is adapted to be plugged with a connecting rod 6.4 that is slidably connected to the bar 6.3. A clamping strip 6.6 fixed to each connecting rod 6.4 is provided in the long groove 6.5. The clamping strip 6.6 has an extended state in which it is clamped with the round mouth unit 4.21 and an avoidance state in which it is completely retracted into the long groove 6.5. The specific sliding connection method is that the cross section of the rod body of the bar 6.3 is a rectangular rod, and a plurality of long strip openings 6.8 corresponding to the connecting rod 6.4 are opened on the side of the bar 6.3, and the angle between the length direction line of the long strip opening 6.8 and the length direction line of the bar 6.3 is in the range of 40 degrees to 45 degrees, and the preferred angle between the length direction line of the long strip opening 6.8 and the length direction line of the bar 6.3 is 45 degrees. The bottom end of the connecting rod 6.4 is provided with a card slot 6.9 that is engaged with the bar 6.3, and an axial rod 9 is movably penetrated in the long strip opening 6.8, and the two ends of the axial rod 9 are rotatably connected with the inner wall surface of the card slot 6.9; Preferably, a contact wheel 10 is movably mounted on one end of the bar 6.3 extending outside the plug-in port 6.1, and the wheel body of the contact wheel 10 is connected to the bar 6.3 via a one-way ratchet, and the wheel body of the contact wheel 10 is a non-slip rubber wheel; In actual use, when the extended end of the internal threaded tube 4.22 contacts the track plate layer 7, the bar 6.3 is completely in the plug-in port 6.1 due to the reaction force of the track plate layer 7, and the spring 6.7 is in a compressed and deformed state, and the clamping strip 6.6 is in an evasive state completely retracted into the long strip groove 6.5 under the pulling action of the long strip opening 6.8 and the connecting rod 6.4, that is, the first axis limit unit 6 is in a retracted state; the internal threaded tube 4.22 rotates coaxially with the threaded rod 4.23, and the contact wheel 10 can roll on the track plate layer 7; Similarly, when the extended end of the internal threaded tube 4.22 is away from the track plate layer 7, the clamping strip 6.6 switches from the avoidance state in the long groove 6.5 to the extended state capable of being clamped with the round mouth unit 4.21. It should be specifically explained that in this process, the bar 6.3 is re-extended to the outside of the plug-in interface 6.1 by the elastic deformation recovery force of the spring 6.7. When the bar 6.3 is extended, the contact wheel 10 is still in contact with the track plate layer 7, and the contact wheel 10 cannot rotate under the action of the one-way ratchet. That is to say, when the threaded rod 4.23 rotates forward, the contact wheel 10 can roll on the side of the track plate layer 7, and the friction between the bar 6.3 and the track plate layer 7 is small. When the threaded rod 4.23 rotates backward, the contact wheel 10 cannot roll on the side of the track plate layer 7, and the friction between the bar 6.3 and the track plate layer 7 is maximum, which is conducive to the extension of the card strip 6.6 from the long groove 6.5, and then facilitates the first axis limit unit 6 to switch from the retracted state to the extended state.

[0024] In another embodiment provided by the present invention, the round-mouth unit 4.21 includes a circular mouth 4.211 for the internal threaded tube 4.22 to movably pass through, and a plurality of wheel platforms 4.212 are evenly distributed and installed on the inner wall surface of the circular mouth 4.211, and each wheel platform 4.212 is movably embedded with a support ball 4.213 in contact with the internal threaded tube 4.22, and the ball diameter of the support ball 4.213 is larger than the groove width of the long groove 6.5, and the support ball 4.213 can pass over the long groove 6.5, and a gap space that can be engaged with the extended state clamping strip 6.6 is formed between each wheel platform 4.212. In actual use, the support ball 4.213 can reduce the friction between the wheel platform 4.212 and the outer wall surface of the internal threaded tube 4.22. When the clamping strip 6.6 is engaged with the gap space, the first axis limit unit 6 is in an extended state.

[0025] In another embodiment provided by the present invention, the transmission mechanism 4.3 includes a gear 4.31 meshed with the gear rod 3.21, the gear 4.31 is fixed to one end of the threaded rod 4.23 extending out of the vertical accommodating chamber 4.11, the gear 4.31 is meshed with the gear rod 3.21, when the gear rod 3.21 moves upward with the crossbeam column 3.11 as a reference, the gear 4.31 drives the threaded rod 4.23 to rotate forwardly, the transmission mechanism 4.3 also includes an annular groove 4.32 provided on the circumference of the threaded rod 4.23, the groove side wall on one side of the annular groove 4.32 is in contact with the inner wall surface of the vertical accommodating chamber 4.11, the groove side wall on the other side of the annular groove 4.32 is in contact with the outer wall surface of the side limit column 4.1, and the gear rod 3.21 is limited in the axial direction by the movement of the annular groove 4.32.

[0026] In another embodiment provided by the present invention, the slider unit 5.2 includes a vertical slide groove 5.21 provided on the inner wall surface of the transverse accommodating cavity 3.12, the slider 5.22 is slidably engaged in the vertical slide groove 5.21, the top of the slider 5.22 is provided with a through hole 5.23 for the gear rod 3.21 to movably pass through, a ratchet unit 5.24 is installed in the through hole 5.23, and the ratchet unit 5.24 can limit the downward movement of the gear rod 3.21; The ratchet unit 5.24 includes ratchet teeth 5.241 distributed on both sides of the gear rod 3.21, each ratchet tooth 5.241 is hinged to the inner wall surface of the through hole 5.23, a torsion spring 5.242 is installed on the hinged end of the ratchet tooth 5.241, and the ratchet tooth 5.241 can be unidirectionally meshed with the gear rod 3.21; In actual use, when the gear rod 3.21 moves upward with the cross beam 3.11 as a reference, the ratchet teeth 5.241 allow the gear rod 3.21 to move smoothly. When the gear rod 3.21 moves downward with the cross beam 3.11 as a reference, the ratchet teeth 5.241 and the gear rod 3.21 are engaged and limited, thereby preventing the gear rod 3.21 from moving.

[0027] In another embodiment provided by the present invention, the force applying unit 5.3 includes a threaded column 5.31 spirally installed in the middle part above the crossbeam column 3.11, one end of the threaded column 5.31 extends into the transverse accommodating cavity 3.12, a pressure plate 5.32 located in the transverse accommodating cavity 3.12 is rotatably installed at the bottom end of the threaded column 5.31, the plate surface of the pressure plate 5.32 is parallel to the horizontal plane, a force arm 5.33 is installed at the top end of the threaded column 5.31, the rod body of the force arm 5.33 is hinged to the top side of the threaded column 5.31, and the rod body of the force arm 5.33 can be parallel to the horizontal plane; During actual use, the force arm rod 5.33 rotates around the threaded column 5.31 as the center of the circle, so that the threaded column 5.31 can rotate axially. For example, when the threaded column 5.31 rotates axially in the positive direction, the threaded column 5.31 drives the pressure plate 5.32 to move downward, and the force unit 5.3 is in a downward pressing state. Similarly, when the threaded column 5.31 drives the pressure plate 5.32 to move upward, the force unit 5.3 is in an upward lifting state. Preferably, the force arm rod 5.33 can be selected as a rod body composed of a telescopic sleeve, which can be telescopic for easy storage on the one hand, and can be clamped with the force unit 5.3 on another adjacent group on the other hand, thereby preventing the threaded column 5.31 from loosening.

[0028] In another embodiment provided by the present invention, the lever unit 5.1 comprises a straight rod body 5.11 located in the transverse accommodating cavity 3.12, a fulcrum shaft 5.12 fixed to the wall surface of the transverse accommodating cavity 3.12 movably penetrates the side of the straight rod body 5.11, one end of the straight rod body 5.11 can contact the bottom of the pressure plate 5.32, a slider 5.22 is provided with a slot 5.13 toward one side of the straight rod body 5.11, and the other end of the straight rod body 5.11 extends into the slot 5.13, preferably, a roller 5.14 is rotatably installed on one end of the straight rod body 5.11 located in the slot 5.13, so as to reduce the friction force of the straight rod body 5.11 moving in the slot 5.13; During actual use, when the force-applying unit 5.3 is in a downward pressure state, that is, when the threaded column 5.31 drives the pressure plate 5.32 to move downward, the end of the straight rod body 5.11 that contacts the bottom of the pressure plate 5.32 is squeezed and moves downward, so that the other end of the straight rod body 5.11 moves upward, thereby driving the slider 5.22 to move upward along the vertical slide groove 5.21. At this time, under the meshing action of the ratchet unit 5.24, the gear rod 3.21 moves upward again with the cross beam column 3.11 as a reference, thereby further reducing the vertical spacing between the cross beam column 3.11 and the steel bar 2, thereby further pressing the track plate layer 7 on the base platform 1.

[0029] In another embodiment provided by the present invention, the vertical accommodating chamber 4.11 is provided with a connecting rod 12 fixed to the slider 5.22, there are two connecting rods 12, the length direction lines of the two connecting rods 12 are parallel to the axis of the side limit column 4.1, the connecting rod 12 movably penetrates the bottom wall of the horizontal accommodating chamber 3.12 and the top wall of the vertical accommodating chamber 4.11, and the vertical accommodating chamber 4.11 is provided with a supporting block 13 located below the internal threaded tube 4.22, the two ends of the supporting block 13 are vertically fixed to the corresponding connecting rod 12, the supporting block 13 is an iron block, the top of the supporting block 13 is magnetically adsorbed with a magnet sheet 14, and the top of the magnet sheet 14 is fixed with a friction plate 11; In actual use, when the gear rod 3.21 moves upward again with the cross beam 3.11 as a reference, the friction plate 11 contacts the bottom of the internal threaded tube 4.22. Under the action of friction, the axial rotation of the internal threaded tube 4.22 is limited again. At this time, the protruding end of the internal threaded tube 4.22 further squeezes the side of the track plate layer 7, thereby further pressing the side of the track plate layer 7. When the squeezing force of the protruding end of the internal threaded tube 4.22 on the side of the track plate layer 7 is greater than the friction force between the outer side of the internal threaded tube 4.22 and the friction plate 11, the internal threaded tube 4.22 continues to rotate forwardly with the threaded rod 4.23, and the internal threaded tube 4.22 is in a sliding state on the friction plate 11 until the cross beam 3.11 contacts the track plate layer 7.
