Description

Technical Field

[0001] The present application relates to the field of track technology, and in particular to a track adjustment support device. Background Art

[0002] The track adjustment mechanism is usually used to adjust the installation-specific parameters such as the spacing, height, and inclination requirements of each sleeper before laying the track to ensure that the rail achieves the specified posture in a curve or in a specific scenario, thereby ensuring the normal operation of the train.

[0003] At present, the support device for adjusting the height in the track adjustment mechanism is usually realized by a device such as a screw and a nut. For example, a nut or a screw sleeve structure will be set at the end of the main beam in the track adjustment structure, and the support beam often directly adopts a screw. When the height needs to be adjusted, the screw is driven to rotate by a power device to make the support beam rise or fall. Although the height adjustment can be achieved, there are still certain disadvantages. That is, when the screw rotates, the screw will form a certain torsional force on the main beam, so that the main beam has a tendency to deviate in the horizontal plane, thereby causing a certain adjustment error; in addition, the main beam and the support beam are directly screwed, and the stability of the screw is poor during the adjustment process, and adjustment errors are very likely to occur.

[0037] Reference Figures 1 to 3 As shown, a track adjustment support device provided in this embodiment includes a guide seat 1, an installation cavity 10 is provided inside the guide seat 1, and a screw 2 is rotatably provided inside the installation cavity 10; the installation cavity 10 is set at the side wall opening of the guide seat 1; a connecting member 3, one end of the connecting member 3 is slidably connected to the guide seat 1 along the length direction of the guide seat 1, and is screwed to the screw 2, and the other end of the connecting member 3 is used to connect to the main beam 4.

[0038] The guide seat 1 is vertically arranged, and usually the lower end is used to connect to the ground. The interior of the guide seat 1 is hollow, which is recorded as the installation cavity 10; the screw rod 2 is rotatably arranged in the installation cavity 10, and under the action of external force, the screw rod 2 can rotate relative to the installation cavity 10; the installation cavity 10 is opened on one side of the guide seat 1 for allowing components connected to the screw rod 2 to pass through.

[0039] The connecting member 3 is sleeved on the outside of the guide seat 1 and can slide in the up and down directions relative to the guide seat 1. The sleeve of the connecting member 3 and the guide seat 1 can ensure the stability of the connecting member 3 during the sliding process; in addition, one end of the connecting member 3 sleeved on the guide seat 1 is also threadedly connected to the screw 2 in the mounting cavity 10. When the screw 2 rotates, the rotation of the connecting member 3 is limited by the sleeve relationship between the guide seat 1 and the connecting member 3, so that the rotation of the screw 2 will drive the connecting member 3 to move along the length direction of the guide seat 1, that is, the up and down direction.

[0040] By connecting the main beam 4 and the screw rod 2 through the connecting piece 3 and the guide seat 1, it can be ensured that the rotation of the screw rod 2 only drives the connecting piece 3 to rise or fall, avoiding causing a certain torsional force on the main beam 4, thereby ensuring the accuracy of the adjustment process. At the same time, the guide seat 1 serves as the main support of the main beam 4, which can avoid the screw connection error with the main beam 4 caused by the micro-bending that may occur when the screw rod 2 serves as a support, thereby further ensuring the adjustment accuracy.

[0041] In some further embodiments, a bearing is provided inside the installation cavity 10 , the outer ring of the bearing is connected to the inner wall of the installation cavity 10 , and the inner ring of the bearing is connected to the outer peripheral wall of the screw 2 .

[0042] Exemplarily, the screw 2 can be matched with the guide seat 1 through a bearing, that is, a bearing is arranged inside the installation cavity 10, the outer ring of the bearing is connected to the inner wall of the installation cavity 10, and the inner ring of the bearing is connected to the screw 2. It should be noted that no thread is arranged at the position on the screw 2 where the bearing is connected. Therefore, in order to avoid the formation of the thread of the screw 2 divided by the bearing, the bearing can preferably be arranged at the end of the screw 2.

[0043] In addition, the bearing, the screw rod 2 and the mounting cavity 10 may be fitted with an interference fit.

[0044] In some further embodiments, the number of bearings is two, and the two bearings are respectively located at two ends of the mounting cavity 10 along the length direction of the guide seat 1 .

[0045] Specifically, in actual implementation, two bearings may be provided, one of which is located at the upper end of the installation cavity 10 , and the other is located at the lower end of the installation cavity 10 .

[0046] In some further embodiments, the upper end of the screw rod 2 passes through the outside of the installation cavity 10 for connection with a driving device.

[0047] The upper end of the guide seat 1 is sealed by an end cover, which is provided with a through hole. The upper end of the screw 2 passes through the through hole on the end cover to the outside of the installation cavity 10 for connection with a driving device, which is a power device that drives the screw 2 to rotate, such as an electric motor.

[0048] In some further embodiments, the connecting member 3 includes a connecting sleeve 31 and two connecting handles 30. The two connecting handles 30 are arranged on a side wall of the connecting sleeve 31 at intervals along the arrangement direction of the sleepers. A clamping groove for clamping the end of the main beam 4 is formed between the two connecting handles 30; the connecting sleeve 31 is sleeved on the outside of the guide seat 1.

[0049] The structure of the connecting sleeve 31 is the same as that of the square steel pipe. The two connecting handles 30 are plate-like structures. The two connecting handles 30 are arranged at intervals on a side wall of the connecting sleeve 31. The two opposite side walls of the two connecting handles 30 and a side wall of the connecting sleeve 31 where the connecting handles 30 are set together form a clamping groove for clamping the main beam 4.

[0050] The side of the connecting sleeve 31 where the connecting handle 30 is arranged faces the main beam 4 .

[0051] The connecting sleeve 31 is sleeved on the outside of the guide seat 1 . When installing, the connecting sleeve 31 can be sleeved in from the upper end or the lower end of the guide seat 1 .

[0052] Under the action of the connecting sleeve 31, a function similar to that of a guide rail slider is formed between the inner wall of the connecting sleeve 31 and the outer wall of the guide seat 1, thereby achieving stable sliding cooperation between the two. Since the connecting piece 3 is directly connected to the main beam 4, the cooperation between the connecting sleeve 31 and the guide seat 1 can eliminate the torsional effect that the screw rod 2 may bring to the connecting piece 3, thereby avoiding affecting the main beam 4.

[0053] In some further embodiments, the mounting cavity 10 is provided at a set of opposite side wall openings of the guide seat 1 .

[0054] The mounting cavity 10 is opened on a set of opposite side walls of the guide seat 1 to increase the connection strength between the screw rod 2 and the connecting sleeve 31 .

[0055] In some further embodiments, the connecting member 3 also includes a sliding block 6 located inside the installation cavity 10, which is sleeved on the screw rod 2 and threadedly connected to the screw rod 2; a connecting column 60 is provided on the side of the sliding block 6 facing the opening on the guide seat 1, and the connecting column 60 is located in the opening, and the connecting sleeve 31 is connected to the connecting column 60 by a bolt 61.

[0056] The sliding block 6 rises or falls along the length direction of the screw rod 2 under the rotation of the screw rod 2. A connecting column 60 is provided on the side of the sliding block 6 facing the opening, that is, the connecting column 60 is arranged on the two opposite side walls of the sliding block 6. The two connecting columns 60 are respectively located in the two openings. It should be noted that the two openings have a certain length in the length direction of the guide seat 1 to meet the need for the connecting column 60 to give way during the up and down movement of the sliding block 6 relative to the stud.

[0057] The connecting sleeve 31 is connected to the connecting column 60 via a bolt 61 . Specifically, the bolt 61 can be screwed from the outer wall of the connecting sleeve 31 into the interior of the connecting column 60 .

[0058] In some further embodiments, the two connecting handles 30 are provided with connecting holes, a pin shaft 70 is passed through the connecting holes, and a locking piece for locking the two connecting handles 30 and the main beam 4 is provided at the end of the pin shaft 70 .

[0059] The main beam 4 is connected to the two connecting handles 30 via a pin shaft 70 , and the locking piece is used to lock the connecting handle 30 and the pin shaft 70 .

[0060] In some further embodiments, the locking member includes a locking bolt 71 and a locking washer 72. The number of the locking bolt 71 and the locking washer 72 are both two. The two locking bolts 71 are screwed on the end surface of the pin shaft 70, and the locking washers 72 are correspondingly sleeved on the locking bolts 71.

[0061] When it is necessary to lock the main beam 4 and the connecting handle 30, the locking bolt 71 is tightened, the locking bolt 71 abuts against the locking gasket 72, the locking gasket 72 abuts against the connecting handle 30, and the locking bolt 71 is screwed into the end face of the pin shaft 70, thereby achieving the locking of the main beam 4 and the connecting handle 30.

[0062] In actual situations, both ends of the main beam 4 are provided with connecting parts 3, a guide seat 1 and components inside the guide seat 1. When adjusting some bends, the connecting parts 3 at both ends of the main beam 4 need to be at different heights to make the main beam 4 present a certain inclination angle. Therefore, in some embodiments, two connecting holes are provided, one of which is close to the middle of the main beam 4 and is in the shape of a narrow groove to meet the adjustment needs.

[0063] In addition, in some other embodiments, in order to further ensure the firmness of the main beam 4 after tilting, a fastening bolt 61 is provided on a pair of side walls along the length direction of the guide seat 1 on the main beam 4, and the fastening bolt 61 passes through the two side walls and at the same time passes through the pin shaft 70 in the narrow groove-shaped connecting hole therein, so that the original locking relationship between the connecting handle 30 and the side wall of the main beam 4 is changed into the locking relationship between the connecting handle 30 and the side wall of the main beam 4 and the locking relationship between the pin shaft 70 and the fastening bolt 61, thereby further ensuring the locking effect of the connecting member 3 on the main beam 4 after the angle of the main beam 4 is adjusted.

[0064] In some further embodiments, a mounting seat 5 is further included, and the mounting seat 5 is connected to the bottom of the guide seat 1.

[0065] The mounting seat 5 is arranged at the bottom of the guide seat 1 and can be connected by bolts. The mounting seat 5 can increase the height of the guide seat 1.

[0066] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features applied for herein.
