Description

Technical Field

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

[0002] Large, high-speed test trailers often feature high-precision, heavy-duty tracks, often hundreds of meters long. Extremely high precision is required for tread levelness, side straightness, track inclination (lateral levelness), and track pitch (longitudinal levelness). For example, tread levelness must be ≤0.4mm / 200m, side straightness ≤0.4mm / 200m, track inclination ≤0.2mm / m, and track pitch ≤0.05mm / m. Trailers weigh over 100 tons, and wheel loads can range from 10 to 40 tons.

[0003] Traditional track supports are inconvenient to adjust the track's lateral and longitudinal inclinations, and cannot achieve pre-tightening of the track. The track supports are usually in an unloaded state. When the trailer load is applied to the track supports, the track supports themselves sink after being subjected to the force, causing the track to sink, resulting in poor track accuracy and affecting the trailer's operating accuracy. When the trailer track foundation settles irregularly, the traditional track supports require a large number of gaskets to readjust the track accuracy, which makes adjustment troublesome.

[0038] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, 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-duty rail support, such as Figure 1-16As shown, the pre-stressed four-dimensional heavy-duty rail support includes: an embedded steel plate 2 provided below the rail body 1, the embedded steel plate 2 is provided in the concrete foundation; a base 3 provided on the embedded steel plate 2, the top of the base 3 is arranged in an inclined shape; an upper slider 4 slidingly provided on the top of the base 3, the bottom of the upper slider 4 is arranged in an inclined shape 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 pressure plates 5 provided on the top of the base 3, a group of pressure plates 5 is pressed on the rail body 1; a group of embedded long screws 6 are all embedded in the concrete foundation, a group of embedded long screws 6 all pass through the embedded steel plate 2, the base 3 and a group of pressure plates 5; an adjustment mechanism provided on the base 3 for adjusting the rail body 1; an auxiliary monitoring mechanism provided on the embedded steel plate 2 for auxiliary monitoring of the settlement of the concrete foundation.

[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 bears the trailer load, due to the existence of pre-tightening, the settlement can be significantly reduced, the track accuracy is maintained, and the high precision of the trailer operation is ensured. 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 an enlarged hole diameter and a thickened thickness relative to the pressure plate 5. 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 completed 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, improving the quality of trailer operation. 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 bolts 8, and the lateral position of the upper slider 4 can be adjusted left and right by turning the height adjustment bolts 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 bolts 7 and the side adjustment bolts 8. There is no need to use a large number of gaskets, which improves the adjustment efficiency. By introducing the height adjustment bolts 7 and the side adjustment bolts 8, the track body 1 has the ability to be precisely adjusted in both vertical and horizontal directions, further improving 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. 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. 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 the accuracy of the rail body 1 needs to be adjusted, 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 fixed screw 10. The posture adjustment bolt 12 is sleeved on the fixed 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 the screw 10 is locked, it can not only ensure good vertical force support while reducing the installation horizontal accuracy requirements of the welding base plate 9, but also provide the base 3 with strong horizontal anti-movement ability.

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

[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 operating 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 prisms. Prisms are arranged at multiple points on the track body 1. The prisms are used in conjunction with measuring equipment such as a total station to form a monitoring network that comprehensively reflects changes in the concrete foundation. The total station regularly collects data and compares it with the original coordinate values, which can promptly detect the settlement of the concrete foundation.

[0051] After installing the connecting 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 moving mechanism to move the prism frame 14, so that the prism frame 14 slides from the connecting 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 connecting 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, so that the prism frame 14 slides into the connecting box 13, and protects the connecting box 13, which is conducive to the long-term use of the prism frame 14, and can also prevent external objects from damaging the prism frame 14. Through the combination of the one-way screw 15 and the connecting frame 16, the flexible movement of the prism frame 14 is achieved, so that the position of the prism frame 14 can be precisely 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. The movement operation of the prism frame 14 is driven by the motor 19, so that the position of the prism frame 14 is automatically adjusted, and the adjustment efficiency and accuracy are improved. 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 provided 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 slidingly connected to the connecting box 13 and extend out of the connecting box 13; a limiting plate 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 engaged with each other.

[0057] In this embodiment, after the rail 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 rail body 1 and the top of the embedded steel plate 2 respectively, thereby reinforcing the connecting box 13. A group of limit plates 24 are respectively in contact with the rail body 1 and the embedded steel plate 2, thereby reinforcing the connecting box 13 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 tooth of the ratchet 27 contacts the inclined surface of the pawl 28. As the handle 25 rotates further, the pawl 28 is pushed by the tooth, slides along its inclined surface and gradually gets stuck in the tooth, 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 position of the handle 25 is reliably locked, which enhances its stability during operation and is beneficial to 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, and 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 action 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 this 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. 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 slidingly 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 engaged with a group of connecting gears 38, and an electric telescopic rod 40 is fixedly installed on the first rack 39. 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. A chain 34 is sleeved on the two sprockets 33, and the chain 34 is engaged with the two sprockets 33.

[0064] In this embodiment, when the prism frame 14 needs to slide into the connecting 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 cover is arranged on the motor 19, the chain 34, the connecting gear 38 and the first rack 39. Through the engagement 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.

[0065] In another embodiment of the present invention, a solar panel 36 is installed on the top of the connection box 13 , and a power storage device 37 is installed on the top of the inner wall of the connection box 13 . The power storage device 37 is connected to the solar panel 36 by wires.

[0066] In this embodiment, the solar panel 36 is arranged on the top of the connection box 13. This position can maximize the reception of sunlight 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 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.
