Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically to a rail installation support frame screw rotation device. Background Technology

[0002] A track support frame is a piece of equipment used to fix the track, adjust the track gauge, and adjust the track elevation during the laying of a monolithic track bed. It mainly consists of components such as main support rods, adjusting screws, base support plates, and adjusting pads. Track support frames play a crucial role in railway construction, effectively adjusting track alignment and rail surface height to ensure track stability and dimensional accuracy.

[0003] Currently, when using track support frames, the height of the support frame is mostly adjusted by rotating the hexagonal block at the end of the adjusting screw. However, due to the limitations of the screw installation position in the track support frame, manually rotating the hexagonal block is easily obstructed by the installation position and is quite inconvenient. Therefore, an electric wrench is also used to rotate the hexagonal block.

[0004] When adjusting the height of the mounting bracket using an electric wrench, the size of the hexagonal block at the end of the lead screw of different track support brackets varies. It is necessary to replace the rotating head of the electric wrench for adaptation. Moreover, after long-term use, corrosion and deformation can cause the rotating head to fail to match the hexagonal block properly, resulting in the lead screw not being able to rotate. Therefore, in view of this, a track mounting support bracket lead screw rotating device is proposed to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a track mounting support frame screw rotation device to solve the technical problems mentioned in the background art. These problems include the fact that existing track mounting support frame screws mostly rely on hexagonal blocks and electric wrenches for rotation to adjust the height of the mounting frame. Furthermore, hexagonal blocks come in different sizes, requiring the replacement of the electric wrench's rotating head for adaptation. Additionally, after prolonged use, corrosion and deformation can cause the rotating head to become unsuitable for matching the hexagonal block, resulting in the screw failing to rotate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a track mounting support frame screw rotation device, comprising:

[0007] The mounting bracket has a handle at one end;

[0008] A rotating ring is rotatably disposed at the end of the mounting bracket along its axis;

[0009] The fixed claw is hinged to the inner side of the rotating ring, and both the fixed claw and the inner side of the rotating ring are provided with multiple sets of protruding ridges.

[0010] A control component, disposed on the rotating ring and connected to the fixed claw, drives the fixed claw to swing about its hinge point; and

[0011] A drive assembly is mounted on the mounting bracket and connected to the rotating ring to drive the rotating ring to rotate.

[0012] In a preferred embodiment, the control component includes:

[0013] A threaded knob, screwed onto the rotating ring; and

[0014] An abutting ball is located at the end of the threaded knob and abuts against the outside of the fixing claw.

[0015] In a preferred embodiment, the driving component includes:

[0016] A toothed ring is disposed on the outer circumferential surface of the rotating ring;

[0017] A drive gear, rotatably mounted on the mounting bracket along its axis, and meshing with the gear ring; and

[0018] The drive motor is fixedly mounted on the mounting bracket, and its output shaft is connected to the drive gear.

[0019] In a preferred embodiment, the mounting bracket has a sliding groove, the handle is provided with a connecting bracket, and the end of the connecting bracket is provided with a connecting roller, which is slidably engaged in the sliding groove.

[0020] In a preferred embodiment, the connecting frame has a Z-shaped cross-section.

[0021] In a preferred embodiment, the mounting bracket is provided with a carrying handle slot.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This device is used with a hand handle. In use, the rotating ring is placed on the hexagonal block at the end of the lead screw to be rotated. The control component then drives the fixing claw to swing along its hinge point, causing the fixing claw to engage with the inner side of the rotating ring to clamp the hexagonal block. The hexagonal block at the end of the lead screw is fixed by the fixing claw and multiple sets of protrusions on the inner side of the rotating ring. Finally, the drive component controls the rotating ring to rotate along its axis, thus rotating the electric lead screw. This device can accommodate hexagonal blocks of different sizes or other shapes at the end of the lead screw. Even if the hexagonal block corrodes or deforms, it can still quickly and effectively fix the rotating ring to the hexagonal block, eliminating the need for frequent replacement of the electric wrench's rotating head and improving work efficiency.

[0024] Furthermore, during the rotation of the lead screw, the lead screw is eccentrically fixed within the rotating ring. As the rotating ring rotates, the mounting frame slides on the connecting roller via a sliding groove, preventing the eccentric movement of the rotating ring from being transmitted to the operator's arm, making the device more convenient and comfortable to use. After use, the connecting frame can be flipped along the connecting roller, folding the device and reducing its space requirements when carried. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0032] Example:

[0033] like Figure 1 , 3As shown, this utility model provides a track mounting support frame screw rotation device, including a mounting frame 1. One end of the mounting frame 1 is provided with a handle 7, and the other end of the mounting frame 1 is also provided with a rotatable rotating ring 10. A fixing claw 11 is hinged to the inner side of the rotating ring 10. Both the fixing claw 11 and the inner surface of the rotating ring 10 are provided with multiple sets of protruding ribs 12. A control component connected to the fixing claw 11 is provided on the rotating ring 10, and the control component drives the fixing claw 11 to swing along its hinge point. The control component includes a threaded knob 13 screwed onto the rotating ring 10, and the end of the threaded knob 13 is provided with an abutment ball 14, which abuts against the outer side of the fixing claw 11.

[0034] The device can be used by holding the handle 7. The rotating ring 10 is placed on the hexagonal block at the end of the lead screw to be rotated. Then, the threaded knob 13 is rotated to make it slide on the rotating ring 10. The fixing claw 11 is pushed to rotate along the hinge point between the fixing claw 14 and the rotating ring 10 through the abutment ball 14. This can fix hexagonal blocks of different sizes. The setting of the fixing claw 11 and the inner protrusion 12 of the rotating ring 10 effectively prevents the hexagonal block from rotating relative to the device.

[0035] like Figure 1 , 3 As shown, in this embodiment, the mounting frame 1 is provided with a drive assembly connected to the rotating ring 10, which drives the rotating ring 10 to rotate. The drive assembly includes a toothed ring 9 disposed on the outer circumference of the rotating ring 10, and a drive gear 3 rotatably disposed on the mounting frame 1 along its axis. The drive gear 3 meshes with the toothed ring 9. A drive motor 2 is fixedly disposed on the mounting frame 1, and the output shaft of the drive motor 2 is connected to the drive gear 3.

[0036] After the hexagonal block is securely fixed to the rotating ring 10, the drive motor 2 can be started to drive the drive gear 3 to rotate. During the rotation, the drive gear 3 meshes with the gear ring 9 to drive the rotating ring 10 to rotate, thereby rotating the lead screw and achieving the purpose of rotating the lead screw. In addition, in some preferred embodiments, the number of teeth of the drive gear 3 can be set to be less than the number of teeth of the gear ring 9 to increase the torque and achieve stable force transmission.

[0037] like Figure 1 , 2 As shown, in this embodiment, the mounting frame 1 is provided with a sliding groove 4, the handle 7 is provided with a connecting frame 6, the end of the connecting frame 6 is provided with a connecting roller 5, the connecting roller 5 is slidably locked in the sliding groove 4, and the connecting block is eccentrically set in the rotating ring 10, so that the hexagonal block can drive the mounting frame 1 to move as a whole during the rotation, thereby making the mounting frame 1 move on the connecting roller 5, so as to reduce the vibration transmitted to the worker's hand.

[0038] like Figure 1 , 2As shown, in this embodiment, the connecting frame 6 has a Z-shaped cross section, and the connecting frame 6 can be rotated and flipped along the axis of the connecting roller 5 to fold the device. A carrying slot 8 is provided on the mounting frame 1 for easy carrying.

[0039] The specific usage and beneficial effects of this utility model are as follows:

[0040] The device is used by holding the handle 7. In use, the rotating ring 10 is fitted onto the hexagonal block at the end of the lead screw to be rotated. The control component then drives the fixing claw 11 to swing along its hinge point, causing the fixing claw 11 to engage with the inner side of the rotating ring 10 to clamp the hexagonal block. The hexagonal block at the end of the lead screw is fixed by the fixing claw 11 and multiple sets of protrusions 12 on the inner side of the rotating ring 10. Finally, the drive component controls the rotating ring 10 to rotate along its axis, thus rotating the electric lead screw. This device can rotate the lead screw to accommodate hexagonal blocks of different sizes or other shapes at the end of the lead screw. Even if the hexagonal block corrodes or deforms, the rotating ring 10 can be quickly and easily fixed to the hexagonal block, eliminating the need for frequent replacement of the electric wrench's rotating head and improving work efficiency.

[0041] Furthermore, during the rotation of the lead screw, the lead screw is eccentrically fixed within the rotating ring 10. As the rotating ring 10 rotates, the mounting frame 1 slides on the connecting roller 5 via the sliding groove 4, preventing the eccentric movement of the rotating ring 10 from being transmitted to the operator's arm, thus making the device more convenient and comfortable to use. After use, the connecting frame 6 can be flipped along the connecting roller 5 to fold the device, reducing the space it occupies when carried.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
