As shown in fig. 1-3, the present application provides a protection device for preventing a pull rope from coming out of a slot, which is disposed on a gantry crane, the gantry crane includes a pull rope, the pull rope is reversed by a rotating wheel to hang a cargo, and the cargo is lifted and transported to a target position and then placed on the ground.

The surface of the rotating wheel is provided with a rotating wheel groove used for connecting the traction rope, the traction rope can be in a loose state in the process of hoisting and placing goods, and at the moment, the traction rope is easy to fall off from the rotating wheel groove on the surface of the rotating wheel.

The groove protection device is prevented out by haulage rope that this application relates to can improve the stability that haulage rope (like wire rope) connects in the runner groove, prevents that the haulage rope from deviating from the runner inslot under the state of lax, simultaneously, also can receive external force and pull the effect down by force, in time gives operating personnel with the maloperation signal output to and the equipment of shutting down in time.

The traction rope groove-preventing protection device comprises a mounting base 10, a fixing member 20, a protection member 30 and an elastic member 40, wherein the mounting base 10 is formed on the gantry crane, the bottom of the fixing member 20 is fixed on the mounting base 10, and the protection member 30 is rotatably connected on the fixing member 20.

A protection port 31 is formed at a height corresponding to the runner above the protection member 30, an opening direction of the protection port 31 faces the runner, and both sides of the protection port 31 are respectively located at the upper and lower sides of the runner and are used for limiting a traction rope connected in a runner groove.

Specifically, the shield 30 is provided with a first blocking rod 311 and a second blocking rod 312 at intervals perpendicular to the height direction of the shield 30, the shield port 31 is formed between the first blocking rod 311 and the second blocking rod 312, and the first blocking rod and the second blocking rod 312 are respectively located on both sides of the runner.

The protection member 30 is connected with an elastic member 40, and when no external force is applied, the elastic member 40 exerts a force on the protection member 30 to abut the protection member 30 on the fixing member 20, and when the external force is applied, the protection member 30 generates a backward overturning action relative to the fixing member 20 by overcoming the force of the elastic member 40.

The acting force of the elastic member 40 can limit the hauling rope to a certain extent, and when the hauling rope is in a loose state during hoisting and landing, the protection member 30 can limit the position of the hauling rope, so that the hauling rope is prevented from falling out of the runner groove in the state.

When the pulling rope is released from the pulley groove in a state of misoperation of a driver, the pulling rope is pulled by a large external force, and the protection member 30 is turned backwards relative to the fixing member 20 under the action of the external force.

Referring to fig. 4, in some embodiments of the present application, in order to transmit the misoperation signal to the operator in time in the misoperation state, the mounting base 10 is further connected with a sensing member 60 through a sensing bracket 61, a sensing range of the sensing member 60 is located at the rear side of the protection member 30, when the protection member 30 is turned over backwards under the action of external force, the sensing member 60 senses the signal, the sensing member 60 is electrically connected with a warning light, the signal is transmitted to the operator, so that the driver can stop operating in time conveniently, and the sensing member 60 can also be directly connected with the switch of the portal crane through the control system, so as to directly stop the switch of the portal crane.

For manufacturing convenience and cost saving, the fixing member 20 and the protection member 30 are both of a channel steel structure, the fixing member 20 includes a first bottom 21 and first side walls 22 on both sides of the first bottom 21, and the protection member 30 includes a second bottom 33 and second side walls 34 on both sides of the second bottom 33.

The securing member 20 has a dimension larger than the securing member 30, i.e. the dimension between the two first side walls 22 on the securing member 20 is larger than the largest dimension of the two second side walls 34, and the securing member 30 is connected between the two first side walls 22 in the mounted state.

Since the protection member 30 is turned backwards between the two first side walls 22 by an external force, to prevent the protection member 30 from interfering with the fixing member 20 during rotation, the protection member 30 has a relief portion 32 formed at the bottom of the two second side walls 34, and the relief portion 32 is in the shape of a circular arc.

The elastic member 40 may be disposed between the first bottom surface 21 and the second bottom surface 33, or between the first sidewall 22 and the second sidewall 34.

Referring to fig. 4 to 6, when the elastic member 40 is disposed between the first bottom surface 21 and the second bottom surface 33, the first connection hole 23 is formed on the first bottom surface 21, the second connection hole 35 is formed on the second bottom surface 33, a bolt 41 is installed between the first connection hole 23 and the second connection hole 35, the length of the bolt 41 is greater than the connection size between the first connection hole 23 and the second connection hole 35, and the bolt 41 extends outward by a certain length after passing through the first connection hole 23 and the second connection hole 35.

The elastic member 40 is sleeved on the bolt 41 extending to the outer side of the second bottom surface 33, the elastic member 40 is in a compressed state, the size of the first connecting hole 23 is larger than the outer diameter of the bolt 41, when the protection member 30 is overturned, the elastic member 40 continues to be compressed, the bolt 41 is subjected to small-range angle change, and the size of the first connecting hole 23 is slightly larger, so that interference can be avoided.

All be provided with the gasket on first connecting hole 23, the second connecting hole 35 for improve the suitability of bolt 41 and first connecting hole 23 and second connecting hole 35
