Description

Technical Field

[0001] The invention belongs to the technical field of track supports, and in particular relates to a pre-loaded four-dimensional heavy-duty track support. Background Art

[0002] In large-scale high-speed test trailers, high-precision heavy-duty tracks are often installed. These tracks are usually hundreds of meters long, and the tread levelness, track side straightness, track inclination (lateral levelness), track pitch (longitudinal levelness) and other precision requirements are extremely high. For example, the tread levelness is ≤0.4mm / 200m, the side straightness is ≤0.4mm / 200m, the track inclination is ≤0.2mm / m, and the track pitch is ≤0.05mm / m. The trailer mass is more than 100 tons, and the wheel pressure can reach 10 to 40t.

[0003] Traditional track supports are inconvenient for adjusting the lateral and longitudinal inclinations of the track, and cannot pre-tighten the track. The track supports are usually in an unloaded state. When the trailer load is applied to the track supports, the track supports sink after being subjected to the force, causing the track to sink, resulting in poor track accuracy and affecting the trailer's running accuracy. When the trailer track foundation sinks irregularly, the traditional track supports require a large number of gaskets when readjusting the track accuracy, which makes adjustment troublesome.

The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned figures are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0038] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] The embodiment of the present invention provides a pre-compressed four-dimensional heavy rail support, such as Figure 1-16As shown, the pre-stressed four-dimensional heavy-duty rail support includes: an embedded steel plate 2 arranged below the rail body 1, the embedded steel plate 2 is arranged in a concrete foundation; a base 3 is arranged on the embedded steel plate 2, and the top of the base 3 is arranged in an inclined state; an upper slider 4 is slidably arranged on the top of the base 3, the bottom of the upper slider 4 is arranged in an inclined state and contacts with the top of the base 3, and the upper slider 4 is used to support the rail body 1; a group of pressing plates 5 are arranged on the top of the base 3, and the group of pressing plates 5 are pressed on the rail body 1; a group of embedded long screws 6 are all embedded in the concrete foundation, and the group of embedded long screws 6 all penetrate the embedded steel plate 2, the base 3 and the group of pressing plates 5; an adjustment mechanism arranged on the base 3 for adjusting the rail body 1; an auxiliary monitoring mechanism arranged on the embedded steel plate 2 for auxiliary monitoring of concrete foundation settlement.

[0040] In this embodiment, the adjustment mechanism is first operated to adjust the lateral inclination and longitudinal inclination of the track body 1 according to actual needs to ensure that the track body 1 reaches the optimal operating state. By tightening the pressure plate 5 and utilizing the tension of the embedded long screw 6, the track body 1 is pre-tightened so that it is closely fitted with the foundation in an unloaded state, reducing the settlement caused by the load. When the track body 1 is subjected to the trailer load, the existence of pre-tightening can significantly reduce the settlement, maintain the track accuracy, and ensure the high accuracy of the trailer operation. When the exposed thread length of the embedded long screw 6 is insufficient, the spherical nut on the embedded long screw 6 can be replaced with an extended spherical nut 6-1, and the pressure plate 5 can be replaced with a thickened pressure plate. The thickened pressure plate has a larger hole diameter and a thicker thickness relative to the pressure plate 2. At the same time, the threaded portion of the posture adjustment bolt 12 can be lengthened. After this improvement, the device can adapt to foundation settlement of 30 to 50 mm.

[0041] When the track accuracy needs to be readjusted, it can be done quickly and accurately using the adjustment mechanism and monitoring equipment, reducing the use of gaskets and the complexity of adjustment. Through pre-compression and precise adjustment, it is ensured that the track body 1 still maintains high precision under load, thereby improving the running quality of the trailer. The pre-compression design effectively reduces the settlement of the track body 1 under load and extends the service life of the track body 1.

[0042] In a further preferred embodiment of the present invention, the adjustment mechanism includes: height adjustment bolts 7 threadedly installed on both sides of the base 3, and the ends of the height adjustment bolts 7 are in contact with both sides of the upper slider 4; side adjustment bolts 8 threadedly installed on both sides of the base 3, and the side adjustment bolts 8 are in contact with the rail body 1 through the top cap.

[0043] In this embodiment, during the initial adjustment, the lateral position of the track body 1 can be adjusted laterally by rotating and turning the side adjustment bolt 8, and the lateral position of the upper slider 4 can be adjusted left and right by turning the height adjustment bolt 7, thereby adjusting the height of the track body 1. During the operation of the track support, if the track accuracy needs to be adjusted due to foundation settlement or other reasons, the track accuracy can be quickly restored by adjusting the height adjustment bolt 7 and the side adjustment bolt 8. There is no need to use a large number of gaskets, which improves the adjustment efficiency. By introducing the height adjustment bolt 7 and the side adjustment bolt 8, the track body 1 has the ability to be precisely adjusted in both vertical and horizontal directions, which further improves the adjustment convenience, accuracy and stability of the track body 1.

[0044] In a further preferred embodiment of the present invention, a welding base plate 9 is welded to the top of the embedded steel plate 2, a threaded hole is provided on the welding base plate 9, and the upper end opening of the threaded hole is provided with a concave spherical surface or a conical surface, and a fixing screw 10 is installed on the top of the base 3, and the fixing screw 10 is threadedly connected to the welding base plate 9, and a clamping cover 11 is sleeved on the fixing screw 10, and the clamping cover 11 is in close contact with the top of the base 3.

[0045] In this embodiment, when it is necessary to adjust the accuracy of the rail body 1, fine-tuning can be performed through adjustment mechanisms such as the height adjustment bolts 7 and the side adjustment bolts 8. At the same time, the clamping cover 11 and the fixing screw 10 are used to ensure a firm connection between the base 3 and the welding base plate 9. The close contact between the clamping cover 11 and the top of the base 3 effectively prevents impurities such as dust and moisture from entering the threaded hole, thereby improving the sealing of the connection.

[0046] In a further preferred embodiment of the present invention, a posture adjustment bolt 12 is provided in the threaded hole on the base 3 used in conjunction with the fixing screw 10, the posture adjustment bolt 12 is sleeved on the fixing screw 10, the middle part of the posture adjustment bolt 12 is a through hole, and the bottom end of the posture adjustment bolt 12 is a spherical surface.

[0047] The bottom spherical surface of the posture adjustment bolt 12 cooperates with the concave spherical surface or conical surface of the upper end of the threaded hole of the welding base plate 9. When locking the fixing screw 10, it can not only ensure good vertical force support while reducing the installation horizontality accuracy requirements for the welding base plate 9, but also provide the base 3 with a strong horizontal anti-movement ability.

[0048] In this embodiment, by setting the posture adjustment bolt 12, the overall installation height, lateral inclination and longitudinal inclination of the base 3 can be continuously adjusted, and the base 3 can be pressed against the welding base plate 9 by tightening the nut on the upper part of the fixing screw 10.

[0049] In a further preferred embodiment of the present invention, the auxiliary monitoring mechanism includes: a connection box 13 welded to the top of the embedded steel plate 2, the connection box 13 is located on one side of the base 3; a prism frame 14 is arranged on one side of the connection box 13; a partition 20 fixedly installed in the connection box 13, the partition 20 divides the connection box 13 into a storage chamber and an operation chamber; a moving mechanism arranged in the storage chamber for moving the prism frame 14; and a reinforcement mechanism arranged in the connection box 13 for reinforcing the connection box 13.

[0050] In this embodiment, a prism frame 14 is provided on the side of the connection box 13. The prism frame 14 includes a frame body and a prism. The prisms are arranged at multiple points of the track body 1. The prisms are used in combination with measuring equipment such as a total station to form a monitoring network to fully reflect the changes in the concrete foundation. The total station collects data regularly and compares it with the original coordinate value, so that the settlement of the concrete foundation can be discovered in time.

[0051] After installing the connection box 13, adjust the prism frame 14 to facilitate subsequent long-term use. When it is necessary to use a total station or other measuring equipment to observe the prism frame 14, first start the moving mechanism to drive the prism frame 14 to move, so that the prism frame 14 slides from the connection box 13 and moves the prism frame 14 to one side of the side adjustment bolt 8. After that, the total station can be used to observe the prism frame 14. The design of the connection box 13 and the prism frame 14 facilitates subsequent measurement of the settlement of the concrete foundation, which is conducive to timely detection of the settlement of the concrete foundation.

[0052] In a further preferred embodiment of the present invention, the moving mechanism includes: a mounting plate fixedly mounted on the bottom of the inner wall of the connecting box 13; a one-way screw 15 rotatably mounted on the mounting plate, the one-way screw 15 being provided with a unidirectional thread; a connecting frame 16 threadedly sleeved on the one-way screw 15, the connecting frame 16 being fixedly connected to the prism frame 14; and a driving mechanism provided on the connecting box 13 for driving the one-way screw 15.

[0053] In this embodiment, after the measurement is completed, the driving mechanism is started, so that the driving mechanism drives the one-way screw 15 to rotate, so that the one-way screw 15 drives the connecting frame 16 to slide, so that the connecting frame 16 slides along the connecting box 13, so that the connecting frame 16 drives the prism frame 14 to slide, and the prism frame 14 slides into the connecting box 13, so as to protect the connecting box 13, which is conducive to the long-term use of the prism frame 14, and also can prevent the prism frame 14 from being damaged by external objects. Through the combination of the one-way screw 15 and the connecting frame 16, the flexible movement of the prism frame 14 is realized, so that the position of the prism frame 14 can be accurately adjusted as needed.

[0054] In a further preferred embodiment of the present invention, the driving mechanism includes: a rotating rod 17 rotatably mounted on one side of the inner wall of the connecting box 13; a group of first bevel gears 18 fixedly mounted on the rotating rod 17 and the one-way screw 15 respectively, and the group of first bevel gears 18 are meshed with each other; a motor 19 fixedly mounted on one side of the connecting box 13, and the output shaft of the motor 19 is fixedly connected to the rotating rod 17.

[0055] In this embodiment, when driving the one-way screw 15 to rotate, the motor 19 is first started so that the output shaft of the motor 19 drives the rotating rod 17 to rotate, so that the rotating rod 17 drives the first bevel gear 18 to rotate, and the first bevel gear 18 drives the one-way screw 15 to rotate, so that the one-way screw 15 drives the connecting frame 16 to slide, and the movement operation of the prism frame 14 is driven by the motor 19 to realize the automatic adjustment of the position of the prism frame 14, thereby improving the adjustment efficiency and accuracy. At the same time, the combined design of the motor 19 and the first bevel gear 18 ensures the stability and reliability of power transmission, so that the movement of the prism frame 14 is smoother and more accurate.

[0056] In a further preferred embodiment of the present invention, the reinforcement mechanism includes: a fixed block 21 fixedly mounted on one side of the partition 20; a bidirectional screw 22 rotatably mounted on the fixed block 21, and left-handed and right-handed threads are respectively arranged at both ends of the bidirectional screw 22; a group of threaded barrels 23 respectively threadedly sleeved on both ends of the bidirectional screw 22, and a group of threaded barrels 23 are all slidably connected to the connecting box 13 and extend out of the connecting box 13; limiting plates 24 respectively mounted on a group of threaded barrels 23; a handle 25 rotatably mounted on one side of the connecting box 13; a group of second bevel gears 26 respectively fixedly sleeved on the bidirectional screw 22 and the handle 25, and a group of second bevel gears 26 are meshed with each other.

[0057] In this embodiment, after the track body 1 is installed, the handle 25 is rotated so that the handle 25 drives the second bevel gear 26 to rotate, and the second bevel gear 26 drives the bidirectional screw 22 to rotate, so that the bidirectional screw 22 rotates to drive the threaded cylinder 23 to slide, and the threaded cylinder 23 slides along the connecting box 13, so that a group of limit plates 24 slide and contact the bottom of the track body 1 and the top of the embedded steel plate 2 respectively, and the connecting box 13 is reinforced. A group of limit plates 24 are respectively in contact with the track body 1 and the embedded steel plate 2, so that the connecting box 13 is reinforced to ensure that it will not move during use, and the reinforcement effect is better.

[0058] In a further preferred embodiment of the present invention, a ratchet 27 is fixedly sleeved on the output rod of the handle 25, and a pawl 28 is rotatably installed in the connecting box 13. One side of the pawl 28 is clamped in the teeth of the ratchet 27, and the pawl 28 is arranged in an inclined shape.

[0059] In this embodiment, when a group of limit plates 24 are respectively close to the rail body 1 and the embedded steel plate 2, a certain tooth of the ratchet 27 contacts the inclined surface of the pawl 28. As the handle 25 rotates further, the pawl 28 is acted upon by the thrust of the tooth, slides along its inclined surface and gradually gets stuck in the tooth, thereby realizing the locking function. Once the pawl 28 is completely stuck in the tooth, it will prevent the ratchet 27 from rotating in the opposite direction, thereby locking the position of the handle 25. Through the interaction between the pawl 28 and the ratchet 27, the reliable locking of the position of the handle 25 is realized, thereby enhancing its stability during operation and facilitating the operation of the reinforcement mechanism.

[0060] In a further preferred embodiment of the present invention, a connecting plate is fixedly installed on one side of the inner wall of the operating chamber, a connecting spring 29 is fixedly installed on the connecting plate, the top of the connecting spring 29 is fixedly connected to the pawl 28, a pull rope 30 is installed on the top of the pawl 28, and the pull rope 30 slides and extends out of the connecting box 13.

[0061] In this embodiment, when the limit plate 24 needs to be adjusted, the pull rope 30 is first pulled to make the pull rope 30 drive the pawl 28 to rotate. When the pawl 28 rotates, the connecting spring 29 is stretched, and at the same time, one side of the pawl 28 rotates away from the teeth of the ratchet 27. Then, the handle 25 can be rotated in the opposite direction to reset the limit plate 24. By setting the connecting spring 29, the pawl 28 can respond to the rotation of the ratchet 27 more flexibly, thereby improving the sensitivity of locking and unlocking. At the same time, the elastic force of the connecting spring 29 helps to maintain the stable position of the pawl 28 in the locked state to prevent it from accidentally falling out due to external vibration or impact.

[0062] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0063] In another embodiment of the present invention, one side of the connecting box 13 is set in an open shape, and a mounting block 31 is fixedly installed on the top of the connecting box 13, and a cover 32 is rotatably installed on the mounting block 31, and the cover 32 is adapted to the notch of the connecting box 13. A mounting rod is rotatably installed on one side of the connecting box 13, and a connecting gear 38 is fixedly sleeved on the output rod of the cover 32 and the mounting rod. A first rack 39 is slidably provided on one side of the connecting box 13, and a second rack 41 is provided below the first rack 39. The second rack 41 and the first rack 39 are respectively meshed with a group of connecting gears 38, and an electric telescopic rod 40 is fixedly installed on the first rack 39, and the output rod of the electric telescopic rod 40 is fixedly connected to the second rack 41, and a sprocket 33 is fixedly sleeved on the rotating rod 17 and the mounting rod, and a chain 34 is sleeved on the two sprockets 33, and the chain 34 is meshed with the two sprockets 33.

[0064] In the present embodiment, when the prism frame 14 needs to slide into the connection box 13, the electric telescopic rod 40 is first started, so that the output rod of the electric telescopic rod 40 drives the second rack 41 to slide down, so that the second rack 41 slides down and engages with the connecting gear 38 of the mounting rod, and then the motor 19 is started, so that the output shaft of the motor 19 drives the rotating rod 17 to rotate, so that the rotating rod 17 drives the sprocket 33 to rotate synchronously, so that the sprocket 33 drives the chain 34 to rotate, and then the two sprockets 33 rotate synchronously, so that the mounting rod drives the connecting gear 38 to rotate, and when the connecting gear 38 rotates, it drives the second rack 41 to slide, so that the second rack 41 drives the electric telescopic rod 40 and the first rack 39 thereon to slide, so that the second rack 41 drives the electric telescopic rod 40 and the first rack 39 thereon to slide. A rack 39 drives the connecting gear 38 on the cover 32 to rotate synchronously, so that the cover 32 rotates to one side of the connecting box 13 and seals the opening of the connecting box 13. At the same time, sealing strips are installed on one side of the connecting box 13 and the cover 32 to ensure the sealing performance of the connecting box 13 and the cover 32, and to ensure that moisture, dust and the like do not enter the connecting box 13. A protective cover box 35 is installed on one side of the connecting box 13. The protective box 35 is covered on the motor 19, the chain 34, the connecting gear 38 and the first rack 39. Through the meshing of the connecting gear 38, the first rack 39 and the second rack 41 and the transmission of the chain 34, the smooth and reliable opening and closing action of the cover 32 is ensured.

[0066] In this embodiment, the solar panel 36 is arranged on the top of the connection box 13. This position can receive sunlight to the maximum extent and improve the conversion efficiency of solar energy. The solar panel 36 and the power storage device 37 are directly connected by wires to ensure that the electric energy can be smoothly transmitted and stored, which is conducive to the continuous power supply operation of the motor 19 and the electric telescopic rod 40.
