Detailed Description

The preferred technical solution of the fast grinding carriage of the rotation locking mechanism of the grinding beam clamping rows of grinding wheels is described in detail below with reference to fig. 1 to 7:

example 1:

as shown in fig. 1-3, the fast grinding cart with the rotation locking mechanism for the grinding beam clamped with the rows of grinding wheels comprises a main frame 1, wherein a pair of angle adjusting mechanisms 2 is respectively arranged at two sides below the main frame 1, a rotating mechanism 3 and a rotation locking mechanism 5 are respectively arranged at the inner sides of two ends of each pair of angle adjusting mechanisms 2, and the rotating mechanism 3 and the rotation locking mechanism 5 are used for being arranged on the grinding beam 4 clamped with the rows of grinding wheels.

A polishing beam 4 is arranged between the rotating mechanism 3 and the rotating locking mechanism 5, and rows of grinding wheels are clamped on the polishing beam 4.

The rotary locking mechanism 5 comprises a locking rod 5-1, a locking disc body 5-4 and a follow-up disc 5-5, wherein the follow-up disc 5-5 is fixedly arranged on the polishing beam 4, and the follow-up disc 5-5 rotates along with the polishing beam 4. The locking disc body 5-4 is fixedly arranged on the angle adjusting mechanism 2, the locking rod 5-1 penetrates between the locking disc body 5-4 and the follow-up disc 5-5, one end of the locking rod 5-1 is fixedly provided with an oil cylinder 5-2 and a return spring 5-3 respectively, the oil cylinder 5-2 and the return spring 5-3 are fixedly arranged on the angle adjusting mechanism 2 respectively, and a rigid contact structure matched with a shaft hole is arranged between the locking rod 5-1 and the follow-up disc 5-5.

When the grinding beam 4 rotates to a designated position, a piston rod of the oil cylinder 5-2 extends out to overcome the tension of the return spring 5-3, the disc body 5-4 of the locking disc and the locking rod 5-1 are pushed, the locking rod 5-1 translates leftwards and forms shaft hole matched rigid contact with the follower disc 5-5, the grinding beam 4 and the angle adjusting mechanism 2 are locked into a whole, and the grinding beam 4 is locked to prevent the grinding beam from rotating and realize rotation locking. When the grinding beam 4 needs to continue rotating, the oil cylinder 5-2 is decompressed, the return spring 5-3 contracts to drive the locking disc body 5-4 and the locking rod 5-1 to translate rightwards and separate from the follow-up disc 5-5, the grinding beam 4 and the angle adjusting mechanism 2 are unlocked, and relative rotation and locking and unlocking are achieved.

The working principle of the embodiment is as follows: the locking mechanism is in rigid contact with the components of the grinding beam 4 by moving along the axial direction of the grinding beam 4 so as to lock the grinding beam 4; the rigid contact is released by the locking mechanism in the axial direction of the sanding beam 4 away from the sanding beam 4 part to achieve the unlocking of the sanding beam 4.

The rotating mechanism 3 provides rotating power for the polishing beam 4 to drive the polishing beam to rotate; the rotation locking mechanism 5 can perform locking when the grinding beam 4 rotates to a specified angle, so that the grinding beam 4 stops rotating and maintains the angular position, and the grinding carriage can perform rapid grinding work on the steel rail during traveling of the grinding carriage through the row of grinding wheels on the grinding beam 4 in rigid contact with the steel rail. As can be seen from the above, the rotation locking mechanism 5 is a clutch mechanism that moves axially along the polishing beam 4 to achieve rotation locking and unlocking.

The rotation locking mechanism 5 comprises a follow-up device, a translation device and a translation driving device, wherein the follow-up device is arranged on the polishing beam 4 and rotates along with the polishing beam 4. The translation device and the translation driving device are arranged on the angle adjusting mechanism 2 or other mechanisms on the main frame 1, the translation device does translation motion along the axial direction of the polishing beam 4, the translation device is driven by the translation motion of the translation driving device, so that the servo device is in rigid contact with the translation device, the rotation of the polishing beam 4 is limited, and the purpose of rotation locking is achieved. When the translation driving device drives the translation device to be far away from the follow-up device, the follow-up device and the translation device are in rigid contact, so that the grinding beam 4 is not locked in rotation.

The rotation locking mechanism 5 can preferably adopt any one structure or any combination structure of a rigid friction locking structure of the end face of the follow-up device and the translation device, a shaft hole matching locking structure and an end face tooth meshing locking structure.

The translation device and the translation driving device in the rotation locking mechanism 5 may be locked and unlocked by pure translation movement, or by a combination of translation movement and rotation movement.

The rotational locking mechanism 5 can be extended to be fixed by the translation device, and the translation driving device is arranged on one side of the follow-up device. When the grinding beam 4 rotates to the position, the translation driving device pushes the follow-up device to translate, so that the follow-up device and the translation device are in rigid contact, and the purpose of rotation locking is achieved.

Example 2: similar to example 1, except that: and a return spring 5-3 is cancelled, the oil cylinder 5-2 is replaced by a double-acting oil cylinder, and a piston rod of the double-acting oil cylinder is connected with a locking disc body 5-4. When the rod cavity of the double-acting oil cylinder 5-8 obtains oil pressure, the piston rod translates rightwards to drive the locking disc body 5-4 and the locking rod 5-1 to translate rightwards to be separated from the follow-up disc 5-5, and the purpose of locking and unlocking is achieved.

Example 3: similar to example 1, except that: the return spring 5-3 is replaced by a compression spring, and at the moment, when the oil cylinder 5-2 obtains oil pressure, a piston rod of the oil cylinder pushes rightwards, namely, the compression spring performs rotation locking, and the oil cylinder 5-2 performs locking and unlocking.

Example 4: similar to example 1, except that: the shaft hole matching locking mechanism of the locking disc 5-4, the locking lever 5-1 and the follower disc 5-5 is replaced by an end face gear meshing structure, the end face gear meshing structure comprises a first end face gear and a second end face gear, the first end face gear is installed on the polishing beam 4, the second end face gear replaces the locking lever 5-1 and the locking disc 5-4 to execute translation motion, when the second end face gear is meshed with the first end face gear, rotation locking is achieved, and when the second end face gear is disengaged from the first end face gear, locking and unlocking are achieved.

Example 5: similar to example 1, except that: as shown in fig. 3, 5 and 6, the follower disk 5-5 is replaced with a follower end-toothed disk 5-6, and the lock rod 5-1 is replaced with a lock end-toothed disk 5-7. When the locking end face fluted disc 5-7 is translated to the follow-up end face fluted disc 5-6 in place, the teeth of the two fluted discs are meshed to realize rotary locking; when the locking end face fluted disc 5-7 is far away from the following end face fluted disc 5-6, the engagement is released, namely the locking is released.

Example 6: similar to example 1, except that: as shown in fig. 7, a locking rod 5-1, a locking disc body 5-4 and a return spring 5-3 are canceled, a follower disc 5-5 is mounted on a grinding beam 4, the follower disc 5-5 moves along with the grinding beam 4, an oil cylinder 5-2 is fixedly mounted on an angle adjusting mechanism 2, a piston rod of the oil cylinder 5-2 extends into a hole on the follower disc 5-5 to form shaft hole matching, and then the rotation locking of the grinding beam 4 is realized; when the piston rod of the oil cylinder 5-2 retracts to be far away from the hole on the follow-up disc 5-5, the rotation locking and unlocking of the grinding beam 4 are realized.
