Description
Technical Field
The utility model relates to a gantry crane track fixing technology, especially a gantry crane portable type rail clamping device.
Background
The gantry crane of the T beam yard or the steel bar house needs to be fixed through the rail clamping device when not in use, so that accidents such as 'rail jump' and side turning are prevented. The traditional rail clamping device adopts two steel plates to be temporarily fixed on the rail through threads to achieve the effect of locking the gantry crane. When the crane is needed, the rail clamping device is taken down and placed at a specified position for next use. Because long-term repeated ann, tear steel sheet and screw thread open, screw rod, nut lose easily in the use, perhaps the trade people can not find the rail clamping device scheduling problem after using.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a gantry crane portable type rail clamping device. The loading and unloading are convenient, the operation is simple, and the components can not be lost.
The technical scheme of the utility model: the utility model provides a portal crane portable type rail clamping device, includes 2 curb plates, the one end of dead lever swing joint rail clamping device is passed through to the curb plate lower part, and the other end of rail clamping device is equipped with the draw-in groove, and rail clamping device intermediate junction fastening screw and nut, curb plate upper portion is equipped with the gag lever post.
According to the portable rail clamping device for the gantry crane, the upper portion of the side plate is provided with the sliding groove, and the limiting rod is fixed in the sliding groove through the nut.
The portable rail clamping device for the gantry crane is characterized in that a groove is formed in the middle of the side plate.
According to the portable rail clamping device for the gantry crane, the side plates are arranged on the supporting legs.
The utility model has the advantages that: the utility model discloses a two blocks of curb plates of vertical setting will press from both sides the rail ware and fix on the curb plate, and the dead lever swing joint rail ware is used below, and higher authority gag lever post adopts movable nut, conveniently takes out the rail ware that presss from both sides, adopts the arc recess in the middle of the steel sheet, prevents to block the fastening screw who presss from both sides the rail ware, makes things convenient for collecting of rail ware. When the rail needs to be locked, the rail clamping device is rotated to be directly clamped on the rail, and the fastening screw rod and the nut are screwed tightly. When the rail is not required to be locked, the rail clamping device is rotated upwards and is fixed on the supporting leg by the limiting rod. The time of installing the rail clamping device by an operator at each time is saved, and the potential safety hazard caused by the fact that the screw thread of the rail clamping device is lost or cannot be found in the using process and the rail cannot be locked is solved.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The upper portion of the side plate 1 is provided with a sliding groove 8, the limiting rod 7 is fixed in the sliding groove 8 through a nut, and the limiting rod 7 moves up and down in the sliding groove 8, so that the rail clamping device 3 can be conveniently clamped and taken out.
The middle part of the side plate 1 is provided with a groove 9, so that the movement of the fastening screw 5 of the rail clamping device 3 is not limited.
The side plates 1 are arranged on the supporting legs 10, and the supporting legs 10 are installed or welded below the crane, so that the installation is convenient.
During the use, weld on landing leg 10 with 2 steel sheets earlier, obtain curb plate 1, will press from both sides the one end drilling of rail ware 3, then pass the hole with dead lever 2, swing joint presss from both sides rail ware 3, and the other end that presss from both sides rail ware 3 is draw-in groove 4, presss from both sides rail ware 3 and is 2, and the centre is connected through fastening screw 5, and 4 symmetries of draw-in groove of pressing from both sides rail ware 3 set up, can block track 11. When the rail needs to be locked, the rail clamping device 3 is rotated downwards, the clamping groove 4 is clamped on the rail, and then the fastening screw rod 5 and the nut 6 are screwed tightly. When the rail is not required to be locked, the fastening screw rod 5 and the nut 6 are loosened, then the rail clamping device 3 is rotated around the fixing rod 2 and rotated upwards, the limiting rod 7 is moved upwards firstly, after the rail clamping device 3 is rotated and leaned against tightly, the limiting rod 7 is put down, and the rail clamping device 8 is clamped.
The upper portion of the side plate 1 is provided with a hole, the limiting rod 7 is fixed in the hole through a nut, the limiting rod 7 is inserted into the hole and then the nut is tightened, and the rail clamping device 3 can be clamped.
The distance between the 2 side plates 1 is larger than the length of a fastening screw 5 of the rail clamping device 3, so that the fastening screw 5 can move conveniently without limitation.
The side plates 1 are welded directly below the crane.
During the use, earlier with 2 steel sheet welding in the hoist below, obtain curb plate 1, will press from both sides the one end drilling of rail ware 3, then pass the hole with dead lever 2, swing joint presss from both sides rail ware 3, and the other end that presss from both sides rail ware 3 is draw-in groove 4, presss from both sides rail ware 3 and is 2, and the centre is connected through fastening screw 5, and 4 symmetries of draw-in groove of pressing from both sides rail ware 3 set up, can block track 11. When the rail needs to be locked, the rail clamping device 3 is rotated downwards, the clamping groove 4 is clamped on the rail, and then the fastening screw 5 and the nut 6 are screwed. When the rail is not required to be locked, the fastening screw rod 5 and the nut 6 are loosened, then the rail clamping device 3 is rotated around the fixing rod 2 and rotated upwards, and the limiting rod 7 is inserted into the hole and then the nut is tightened, so that the rail clamping device 3 can be clamped.
