Detailed Description
The present utility model will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present utility model and not limited to the following examples.
The embodiment is a manual rail clamping device used for locking a rail 10 on a movable hoist.
In this embodiment, a base 1 is provided, and a rail clamping mechanism is provided on the base 1. Wherein a rotating shaft 8 is installed on the base 1, a first clamping plate 5 and a second clamping plate 6 are rotatably installed on the rotating shaft 8, and simultaneously, the first clamping plate 5 and the second clamping plate 6 can move along the axial direction of the rotating shaft 8 on the rotating shaft 8. The first clamping plate 5 and the second clamping plate 6 are provided with a first clamping groove and a second clamping groove which are matched with the rail 10 at positions corresponding to the rail 10. First and second mounting holes penetrating through the first and second clamping plates 5 and 6 are respectively arranged at the corresponding positions of the first and second clamping plates 5 and 6, and the first and second mounting holes are coaxial. After the clamping bolt 9 passes through the first mounting hole and the second mounting hole at the same time, a nut is mounted on the end of the protruding clamping bolt 9 through threaded fit. A wrench socket 10 is mounted on the base 1, and a wrench 2 is mounted in the wrench socket 10. Thus, when the track clamping mechanism is required to clamp the track 10, a person removes the wrench 2 from the wrench socket 10 and then unscrews the nut by using the wrench 2, then moves the first clamping plate 5 and the second clamping plate 6 towards two ends on the rotating shaft 8, moves the first clamping plate 5 and the second clamping plate 6 around the rotating shaft 8 to the position of the first clamping groove on the first clamping plate 5 and the position of the second clamping groove on the second clamping plate 6 corresponding to the track 10, moves the first clamping plate 5 and the second clamping plate 6 on the rotating shaft 8 to the position contacting the track 10, and tightens the nut by using the wrench 2 to clamp the first clamping plate 5 and the second clamping plate 6 by matching the nut with the clamping bolt 9, and clamps the track 10 by the first clamping plate 5 and the second clamping plate 6.
In this embodiment, a travel switch 4 is mounted on the base 1, and the first clamping plate 5 contacts the travel switch 4 when the first clamping plate 5 rotates onto the base 1. The travel switch 4 is connected into a circuit of the mobile hoist, when the first clamping plate 5 rotates to a position matched with the travel switch 4, the travel switch 4 is connected with the circuit of the mobile hoist, and when the first clamping plate 5 rotates to a position which is not matched with the travel switch 4 on the base 1, the travel switch 4 is disconnected with the circuit of the mobile hoist. Thus, when the track 10 is not required to be overhauled, the first clamping plate 5 is arranged on the base 1 and is in contact with the travel switch 4, and at the moment, the circuit of the movable hoist is conducted, and a person can operate the movable hoist. When the track 10 is required to be overhauled and maintained, a person rotates the first clamping plate 5 and the second clamping plate 6 to the contact position with the track 10, at the moment, the first clamping plate 5 is separated from the contact position with the travel switch 4, the circuit of the movable hoist is disconnected, the person cannot operate the movable hoist, and damage to the overhauling person due to misoperation in the overhauling and maintenance process is avoided.
In this embodiment, in order to avoid that the first clamping plate 5 leaves the contact position with the travel switch 4 due to vibration or other reasons during the normal operation of the mobile hoist, a stop lever 7 is mounted on the base 1, the stop lever 7 is slidably mounted in a chute on the base 1, and the stop lever 7 is parallel to the rotating shaft 8. When the limiting rod 7 moves to the position matched with the track clamping mechanism in the chute, the limiting rod 7 is matched with the base 1 to clamp the first clamping plate 5 and the second clamping plate 6, so that the first clamping plate 5 and the second clamping plate 6 are prevented from rotating; meanwhile, when the rail 10 needs to be clamped, the limiting rod 7 is moved to a position which is away from the matching position of the rail clamping mechanism in the sliding groove, and the first clamping plate 5 and the second clamping plate 6 can be rotated.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
