The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, a wind-proof device for a traveling crane 100, the traveling crane 100 includes a frame 110 and wheels 120 rotatably disposed on the frame 110, and includes a braking mechanism 200, the braking mechanism 200 includes a transmission member 210 and a driving member, one end of the transmission member 210 is movably connected to the frame 110, the other end of the transmission member 210 is provided with a brake block 230, the driving member is used for driving the transmission member 210 to move, so that the transmission member 210 drives the brake block 230 to extend into a gap between the wheels 120 and a traveling track for braking; and the control mechanism comprises a controller, and the driving piece is electrically connected with the controller.

When the wind speed reaches above the preset wind speed, the controller controls the driving member to drive the driving member 210 to move, so that the driving member 210 drives the brake block 230 to extend between the wheel 120 and the traveling rail, and frictional resistance is formed between the brake block 230 and the wheel 120 and the traveling rail, thereby generating a braking effect and preventing the wind power from pushing the traveling crane 100 to slip to cause an accident.

The traveling crane system includes a supporting truss 400, the supporting truss 400 is supported on the ground or a building 500, as shown in fig. 6, the supporting truss 400 is fixed on the top of the building 500, a first rail 410 and a second rail 420 are provided on the supporting truss 400, a traveling crane 100 (also called a traveling trolley) is provided on the first rail 410 and the second rail 420 (also called a traveling rail), a movable cross beam 430 is set between the first rail 410 and the second rail 420, two ends of the movable cross beam 430 are respectively fixed on the traveling crane 100 on the corresponding rails, when the traveling crane 100 moves along the corresponding traveling rail, the movable cross beam 430 is driven to move, so that the structure hooked on the movable cross beam 430 moves, and materials and the like are conveyed.

However, when wind blows, the wind force is more obviously felt because the traveling crane 100 on the traveling crane system has a certain height, and especially in strong wind weather or typhoon weather, the wind force will generate a large pushing force to the traveling crane 100, and the pushing force will cause the traveling crane 100 to slide on the traveling track, and a light person will deviate a certain distance, which will cause the traveling crane 100 not to be normally controlled to travel, and in a serious case, serious slipping and falling accidents may occur, which causes unnecessary personal and economic losses.

When the wind speed is high or the wind power is high, the controller can be manually started to control the driving piece to drive the driving piece 210 to move, so that the driving piece 210 drives the brake block 230 to move to a gap between the wheel 120 and the walking track, friction is generated between the brake block 230 and the wheel 120 and the walking track, a braking effect is achieved, the crane 100 is prevented from sliding under the action of the wind power, a wind-proof effect is achieved, and construction safety is guaranteed.

Further, the controller may also be triggered and started by an external signal, for example, by providing an external signal input device on a control board of the controller, the signal input device can obtain an external wind speed or wind power signal, and when the external wind speed or wind power reaches or exceeds a preset wind speed, the controller is triggered and started.

Of course, a wind speed detector can be arranged and electrically connected with the controller, and the wind speed detector is used for detecting wind speed. When the wind speed detector detects that the wind power or the wind speed is greater than a preset value, a signal is sent to the controller, the controller receives the signal and then controls the driving part to drive the driving part 210 to move, the driving part 210 drives the brake block 230 to move to a gap between the wheel 120 and the walking rail in the moving process, and the driving part 210 drives the brake block 230 to move to the wheel 120 and the walking rail, so that friction is generated between the brake block 230 and the wheel 120 and the walking rail, a braking action is generated, the braking action and the acting force generated by the wind power are mutually resisted, and the crane 100 is prevented from being damaged by the wind power.

One end of the driving member 210 is provided with a brake block 230, and the driving member 210 is used for transmitting the driving force applied by the driving member to move the brake block 230 between the gap between the wheel 120 and the running rail, so that the driving member 210 may have a rod-shaped structure and a bent structure as required.

The transmission member 210 may be an assembly or a single member, and the transmission member 210 may move or rotate the brake block 230 in any prior art, which is not described in detail herein.

The controller may be any device capable of controlling the driving member, such as a control panel, a PLC, etc., and may be fixedly disposed in the working chamber of the traveling crane system, or may be directly disposed on the traveling crane 100, or of course, the controller may be a remote control terminal; the wind speed detector may be a conventional structure such as a wind speed sensor, which may be disposed outside the crane 100, such as a vehicle body, but may also be a structure that directly obtains wind speed or wind power data from the outside to realize intelligent operation of big data.

The wheels 120 are rotatably disposed on the frame 110, and the wheels 120 move along the traveling rail to drive the frame 110 to move, and the frame 110 may be an elongated box structure as shown in fig. 1.

It should be noted that the driving element can drive the driving element 210 to move forward and backward, and when the driving element normally works, the driving element keeps the driving element 210 in a non-working state, and at this time, the brake block 230 leaves between the wheel 120 and the running rail and does not contact with the wheel 120 and the running rail, so as to avoid affecting the normal running of the wheel 120, and the description is omitted.

When the wind speed is high, the traveling crane 100 is exposed to a large external acting force, at this time, the required braking acting force is high, and it is further necessary to keep the braking acting force unchanged, therefore, by providing two drivers, the first driver 221 is mainly used for driving the gear 240 to rotate to drive the transmission member 210 to move, so that the brake block 230 extends between the wheel 120 and the running rail, and the second driver 222 synchronously drives the transmission member 210 to rotate during the movement of the brake block 230, and when the brake block 230 reaches between the wheel 120 and the running rail and generates the braking acting force, the second driver 222 further keeps the brake block 230 from moving any more, thereby avoiding the situation that the first driver 221 cannot guarantee sufficient braking force when the wind force is too high, and further guaranteeing the reliability of the braking acting force.

The driver can adopt a three-in-one motor, the transmission ratio is large, the output speed is small, and the output torque is large; of course, it should be noted that the first driver 221 and the second driver 222 are electrically connected to the controller, and the controller needs to precisely control the speed matching of the first driver 221 and the second driver 222 so that the gear 240 and the rack 211 are properly matched.
