Abstract
The utility model discloses a track driving safety deceleration braking device, which comprises a stop body, a side baffle, a braking handle, a rotating shaft bidirectional screw rod and a positive and negative rotating nut; the stop body is rotatably provided with a rotating shaft bidirectional screw rod close to the rail, positive and negative rotating nuts are spirally sleeved on two sides of the rotating shaft bidirectional screw rod, side baffles are fixed on the outer side surfaces of the positive and negative rotating nuts, and brake moving handles are fixed at two ends of the rotating shaft bidirectional screw rod. The device is placed on a track, then the braking is carried to anticlockwise rotate to a horizontal state, the two-way lead screw of the rotating shaft rotates along with the braking, and the forward and reverse rotating nuts move towards the side edge of the track to be close to each other in the rotating process, so that the baffles on the two sides are driven to clamp the side edge of the track, the friction force between the braking device and the track is increased, and the crown block is decelerated and stops quickly. Therefore, the braking device has the advantages of simple structure, convenience, rapidness, safety, reliability and high popularity of crown block operators.
Description
One, the technical field
The utility model belongs to the technical field of the braking of rail mounted overhead traveling crane for the mill, concretely relates to track driving safety deceleration braking device.
Second, background Art
In general, when an overhead traveling crane is required to perform maintenance and parking work, a track traveling safety deceleration braking device (commonly called a safety skate) must be arranged between the overhead traveling crane to be maintained and the operating overhead traveling crane to ensure that the maintenance overhead traveling crane is safely and smoothly parked at a predetermined position of a track. Most of the currently applied crown block track traffic safety deceleration braking devices are simple jackscrews in a blocking mode, namely, the braking devices are fixed at corresponding parts of the rails by jackscrews. Since the brake, the crown block wheel and the rail are smooth steel products, the brake is attached to the rail surface, the tip of the brake corresponds to a step, and when the rolling wheel contacts the tip, the force is applied from the wheel, and the force can be decomposed into a vertical downward pressure and a horizontal pushing force in the direction of the brake. Because the contact surface of the jackscrew is small and the stress is very large, when the horizontal thrust force borne by the braking device is larger than the friction force between the braking device and the steel rail, the braking device can slide backwards on the steel rail, so that the overhead traveling crane slips and escapes, the normal parking cannot be realized, and the protection effect cannot be realized. And the condition that the braking device falls off the track also exists, so that objects fall from high altitude, and great potential safety hazards exist.
Third, the invention
The utility model aims at providing a track driving safety deceleration braking device to the technical defect who exists among the prior art, make the overhead traveling crane that needs overhaul stop at the preset position of rail, play the guard action.
Realize the utility model discloses the technical scheme that the purpose was adopted is: the rail traveling safety deceleration braking device comprises a stop body, a side baffle, a braking carrying handle, a rotating shaft bidirectional screw rod and a forward and backward rotating nut; the stop body is attached to the surface of the rail, and the side surface of the stop body is similar to a shoe shape; the stop body is rotatably provided with a rotating shaft bidirectional screw rod close to the rail, positive and negative rotating nuts are spirally sleeved on two sides of the rotating shaft bidirectional screw rod, side baffles are fixed on the outer side surfaces of the positive and negative rotating nuts, and brake moving handles are fixed at two ends of the rotating shaft bidirectional screw rod.
During the application, lay arresting gear on the track, then move the anticlockwise rotation of handle to the horizontality with the braking, the two-way lead screw of pivot follows the rotation, makes the positive and negative rotation nut move towards orbital side edge and draw close to in the rotation process to drive both sides baffle and clip the track side edge, guaranteed that the overhead traveling crane that overhauls stops in the preset position of track.
The utility model has the advantages that: as the two side baffles of the braking device clamp the side edge of the rail, the friction force between the braking device and the rail is increased, so that the crown block is decelerated and rapidly stopped at a preset position. Therefore, the braking device has the advantages of simple structure, convenience, rapidness, safety, reliability and high popularity of crown block operators.
Description of the drawings
Fig. 1 is a side view of the utility model discloses a rail driving safety deceleration braking device.
Fig. 2 is the utility model relates to a rail driving safety deceleration braking device's cross-sectional view.
Fifth, detailed description of the invention
In the attached drawings, the utility model relates to a track driving safety deceleration braking device, which comprises a stop body, a side baffle, a braking handle, a rotating shaft bidirectional screw rod and a positive and negative rotating nut; the stop body 1 is attached to the surface of the rail, and the side surface of the stop body is similar to a shoe shape; the stop body 1 is rotatably provided with a rotating shaft bidirectional screw rod 4 close to a rail, two sides of the rotating shaft bidirectional screw rod 4 are spirally sleeved with forward and reverse rotating nuts 5, the outer side surface of each forward and reverse rotating nut 5 is fixed with a side baffle 2, and two ends of each rotating shaft bidirectional screw rod 4 are fixed with brake moving handles 3. And one side of the threads on the two sides of the two-way screw rod 4 of the rotating shaft is a right side buckle, and the other side of the threads is a reverse side buckle. The braking device is placed on the rail, then the braking handle is moved to rotate anticlockwise to a horizontal state, the bidirectional screw rod of the rotating shaft rotates along with the braking device, the forward and reverse rotating nuts move towards the side edge of the rail to be close in the rotating process, so that the baffles on the two sides are driven to clamp the side edge of the rail, the braking handle is used for moving the dead weight to lock, and the crown block which is maintained is guaranteed to stop at a preset position of the rail. Because the two side baffles of the braking device clamp the side edge of the rail, the friction force between the braking device and the rail is increased, so that the crown block is decelerated and rapidly stops. Therefore, the braking device has the advantages of simple structure, convenience, rapidness, safety, reliability and high popularity of crown block operators.
