Description

Technical Field

[0001] The utility model relates to the technical field of track installation, in particular to a track adjusting device. Background Art

[0002] The traction track is an important part of the traction system and plays a guiding role. In the traction system, the wire rope is usually used to connect the traction trolley. The wire rope passes through the hollow part in the middle of the traction track, bypasses the transmission pulley structure, and finally pulls the vehicle through the traction motor to complete the collision test. Therefore, the straightness and flatness of the traction track affect the accuracy of the entire collision test.

[0003] The straightness and flatness of the track are mainly determined by the track adjustment device under the track. The existing track adjustment device generally includes two adjustment components arranged upper and lower, and a height adjustment structure is provided between the two adjustment components. The upper adjustment component supports the traction track. The height adjustment structure generally adopts adjustment bolts and requires two pourings. The first pouring is the base pouring, and the second pouring is the track installation pouring.

[0004] After the first pouring is completed, before the second pouring, the height adjustment structure needs to be used to level the upper adjustment component. This installation method of the traction track is difficult to ensure the accuracy of the traction track after pouring. In addition, after pouring, it is difficult to ensure the straightness and flatness of the track after pouring because it cannot be checked. Utility Model Content

[0083] The track adjustment device of this embodiment is cast in three steps as a whole, with two layers of adjustment units. The second adjustment unit 5 and the third adjustment unit 6 are arranged on the same layer, so that the track 7 can be adjusted in height and left and right directions.

[0084] When in use, the cushion layer 8 is first laid, and the cushion layer 8 can be concrete, and then the embedded parts 1 are installed. After the embedded parts 1 are installed, the first pouring is performed. After the first pouring layer 9 is poured, the various parts of the adjustment assembly are preliminarily assembled together, and the track 7 is installed in the middle position of the left and right direction of the support 3 (the width direction of the track 7). All parts are connected by screws and nuts, and do not need to be tightened in the current state.

[0085] According to the position of the track 7, several assembled tracks 7 and the track adjustment device are placed in sequence on the embedded part 1, and the track 7 is aligned left and right and at the required position by adjusting the second adjustment unit 5.

[0086] Preliminary inspection is performed to see whether the height of the track 7 can adapt to the ground height, mainly to see whether the height adjustment range is sufficient. After confirmation, the bottom plate 302 is placed on the top plate 101 of the embedded part 1, and then the height is roughly adjusted through the first adjustment unit 4, so that the height and level of the track 7 meet the requirements, and the first adjustment unit 4 is tightened, and then the second pouring is performed. It should be noted here that the height of the track 7 should not be higher than the ground, but slightly lower, because the third adjustment unit 6 can be used to fine-tune the height later, and it can be adjusted higher, but not lowered.

[0087] After the second pouring layer 10 is poured, check whether the height and left and right position (the position in the width direction of the track 7) of the track 7 have changed. If there are any inappropriate places, adjust the third adjustment unit 6 and the second adjustment unit 5 until the requirements are met.

[0088] Then, the casting material is used to wrap the track 7 to ensure the straightness and flatness of the track 7. After the wrapping is completed, the size of the track 7 is checked by a total station (measuring instrument) and its adjustment block. After meeting the requirements of the traction track, the third casting is carried out to complete the installation of the track 7.

[0089] The track adjustment device of this embodiment can perform a final check on the installation accuracy of the track 7 before the construction of the track 7 is completed, and can perform fine adjustments to ensure that the track 7 meets the technical requirements after installation, thereby facilitating the improvement of the accuracy of the collision test.

[0090] In addition, the track adjustment device of this embodiment can solve the problems of too thick cement poured at one time, large thermal collision effect, and poor deformation and solidification effect, which may cause slight changes in the track 7, compared with the existing track 7 installation method. In addition, the track 7 needs to be installed in conjunction with the pulley block. Due to the process requirements, the pulley is shallow from the ground. After the second pouring layer 10 is poured, the pulley can be installed, and then the track 7 accuracy can be adjusted by fine-tuning to ensure the best match between the pulley and the track 7.

[0091] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
