Description

Technical Field

[0001] This utility model belongs to the field of hoisting and positioning technology, specifically relating to an auxiliary mechanism for straightening rail transit guide shafts with hoisting and positioning capabilities. Background Technology

[0002] As the core backbone of the modern integrated transportation system, the operational safety, stability, and durability of rail transit directly depend on the manufacturing precision of its key components. Guide shafts, serving as the transmission and support foundation for core components such as bogies and traction systems in rail transit vehicles, directly affect the uniformity of force distribution, transmission efficiency, and vibration and noise control during train operation due to their straightness accuracy. If the guide shaft is bent or deformed, it will lead to abnormal assembly clearances and localized stress concentrations. Long-term operation can easily cause accelerated component wear, fatigue fracture, and other safety hazards, seriously threatening the operational safety of rail transit.

[0003] Application CN213793574U discloses a hydraulic straightening device for rail transit guide shafts, comprising a straightening device body and two fixing components. Vertical beams are fixedly mounted on both sides of the top of the straightening device body. Each fixing component includes a fixing block, a second slide rail, a second connecting block, a slider, and a lead screw sleeve. The two lead screw sleeves are rotatably connected to the middle of the two lead screws. The two sliders are fixedly mounted on one side of the two lead screw sleeves, and a second connecting block is fixedly mounted on the other side of each slider. The advantages of this invention are: the guide shaft is fixed downwards by the two fixing blocks to achieve a better fixing effect; the gears at the output end of the reversible motor and the toothed plate inside the first slide rail allow the toothed plate to move inside the first slide rail under the drive of the reversible motor, thereby driving the electric hydraulic cylinder at the bottom of the toothed plate to move left and right, realizing the straightening work of the guide shaft body at different positions.

[0004] In practical applications, the aforementioned hydraulic straightening devices for guide shafts have insufficient positioning accuracy. They often employ a single-direction adjustment structure, resulting in significant errors in the coordinated positioning of horizontal displacement and height adjustment, making it difficult to meet the straightening requirements of high-precision guide shafts.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example Reference Figure 1-4 This embodiment of the present invention provides a rail transit guide shaft straightening auxiliary mechanism with hoisting and positioning, comprising: The support assembly 100 includes a base 101, a support frame 102 fixedly connected to the side wall of the base 101, a connector 103 fixedly connected to the end of the support frame 102, a translation track plate 107 slidably connected to the bottom of the connector 103, a translation track 106 slidably installed on the side wall of the translation track plate 107, an auxiliary plate 105 fixedly installed on the side wall of the translation track 106, a translation cylinder 104 fixedly connected to the inner wall of the connector 103, and a reinforcing column 108 fixedly installed on the side wall of the translation track 106. It also includes a connecting plate 109 fixedly installed on the side wall of the reinforcing column 108. The adjustment assembly 200 includes a lifting track plate 201 fixedly installed on the side wall of the connecting plate 109, a lifting track 202 slidably installed on the side wall of the lifting track plate 201, an extension column 203 fixedly installed on one side of the lifting track plate 201, a fixing block 204 fixedly installed on the side wall of the lifting track 202, an adjustment plate 205 rotatably installed on the side wall of the fixing block 204, and straightening blocks 207 fixedly installed at both ends of the adjustment plate 205. It also includes an adjustment cylinder 206 hinged to the side wall of the adjustment plate 205, and the output shaft end of the adjustment cylinder 206 is hinged to the end of another set of side wall brackets of the adjustment plate 205.

[0021] Specifically, the end of the translation cylinder 104 is hinged to the side wall of the connector 103, and the connector 103 is provided with a positioning hole for use with the translation cylinder 104.

[0022] The connector 103 has a reserved positioning hole for cooperating with the translation cylinder 104, which provides a hinged mounting reference for the translation cylinder 104 and ensures the stable transmission of the cylinder driving force.

[0023] Furthermore, the connectors 103 are symmetrically arranged on the outer wall of the support frame 102, and the connectors 103 have arc-shaped edges.

[0024] The outer wall features an arc-shaped edge design, which reduces motion interference with the translation track plate 107 and the translation cylinder 104.

[0025] Furthermore, a limiting plate is installed in the middle of the translation cylinder 104, and the limiting plate in the middle of the translation cylinder 104 extends to the side wall of the connector 103. The slider on the side wall of the translation track plate 107 is connected to the side wall of the reinforcing column 108 by bolts.

[0026] The output shaft of the translation cylinder 104 is indirectly connected to the translation track 106 and transmits power through the auxiliary plate 105, so as to realize the linear reciprocating motion of the translation track 106 along the translation track plate 107.

[0027] Preferably, the end of the reinforcing column 108 is provided with a clamping plate that is fixedly installed on the side wall of the connecting plate 109, and the connecting plate 109 is provided with bolts that cooperate with the clamping plate at the end of the reinforcing column 108.

[0028] The reinforcing column 108 is vertically fixed to the side wall of the translation track 106, and a clamping plate is set at the end. It is fastened to the connecting plate 109 by bolts. The matching design of the clamping plate and bolts greatly improves the connection rigidity and avoids loosening due to vibration during the straightening operation.

[0029] It should be noted that the fixing block 204 is sleeved on the side wall of the lifting rail 202, and the straightening block 207 is symmetrically arranged at both ends of the adjusting plate 205.

[0030] The fixing block 204 is fixed to the side wall of the lifting rail 202 by a sleeve method and is tightened with bolts to ensure a firm connection with the lifting rail 202 and to provide a rotational installation reference for the adjusting plate 205.

[0031] Preferably, the side wall of the adjusting cylinder 206 is provided with a slot for use with the adjusting plate 205, and the adjusting plate 205 is symmetrically installed on the side wall of the fixing block 204.

[0032] Among them, the adjusting cylinder 206 is the power source for angle adjustment. Its side wall has a slot that cooperates with the adjusting plate 205. The end of the output shaft is hinged to the side wall bracket of another set of adjusting plates 205 to ensure that the rotation angle of the adjusting plate 205 is consistent.

[0033] In use, the translation cylinder 104 of the support component drives the adjustment component 200 to move horizontally along the translation track 106 to the preset straightening position. The limiting plate of the translation cylinder 104, together with the symmetrical connecting piece 103 of the support component and the translation track plate 107, ensures positioning accuracy and overall stability. Subsequently, the lifting track 202 slides along the lifting track plate 201 to adjust the height of the straightening block 207 until it is in contact with the guide shaft and locked. Then, the adjustment cylinder 206 drives the symmetrical adjustment plate 205 to rotate synchronously around the fixed block 204, so that the straightening block 207 applies pressure to the guide shaft. A uniform straightening force is applied to calibrate straightness. During the straightening process, the reinforcing column 108, connecting plate 109, and connecting piece 103 of the support component form a rigid support to prevent vibration from affecting the straightening accuracy. The limiting structure of the translation cylinder 104 prevents horizontal displacement. After the operation is completed, the adjusting cylinder 206 is reset, the lifting rail 202 moves down, and the translation cylinder 104 drives the adjusting component to return to the initial position. The whole system achieves accurate and stable straightening of guide shafts of different specifications through the three-dimensional coordination of the horizontal translation of the support component, the height lifting and angle adjustment of the adjusting component.

[0034] In summary, the cooperation between the translation cylinder 104, the limiting plate, the symmetrical connecting piece 103, and the translation track plate 107 significantly improves the horizontal positioning accuracy. The arc-shaped edge design of the connecting piece 103 effectively avoids motion interference, providing a stable benchmark for straightening operations. The clamping bolt connection between the reinforcing column 108 and the connecting plate 109, and the sleeve fastening structure of the fixing block 204 significantly enhance the overall rigidity, resisting loosening caused by straightening vibrations and ensuring accuracy stability. The horizontal translation of the support component 100, the height adjustment of the adjustment component 200, and the synchronous rotation of the symmetrical adjustment plate 205 driven by the adjustment cylinder 206 form a three-dimensional collaborative adjustment system, which can efficiently adapt to guide shafts of different specifications. The uniform correction force applied by the straightening block 207 improves the straightening quality. The power transmission design of the auxiliary plate 105 and the reasonable layout of each component ensure smooth movement, reduce wear, and extend service life. At the same time, the automated drive structure simplifies the operation process and is suitable for large-scale high-precision guide shaft manufacturing scenarios, providing reliable technical support for improving the quality of core components of rail transit.
