Electric winch device for fire truck

Abstract

The invention provides an electric winch device of a fire fighting vehicle and belongs to the technical field of fire fighting vehicles. The fire fighting vehicle comprises a pair of vehicle frame girders. The electric winch device comprises an electric winch, a rope guide and a controller, and is characterized by further comprising an electric winch box, a winch base fixing plate and a winch base, wherein the electric winch box is arranged between the pair of vehicle frame girders, an opening is formed in the right side of an electric winch box cavity, the rope guide is arranged on a winch box cavity bottom plate and corresponds to the center of the opening, the winch base fixing plate is located in the electric winch box cavity, corresponds to the left position of the rope guide and is fixed to the winch box cavity bottom plate, the controller is arranged on the upward side of the winch base fixing plate and corresponds to the lower side of the winch base, the winch base is arranged on the winch base fixing plate in a pivoted mode, and the electric winch is arranged on the winch base and is connected with the vehicle-mounted controller in an electrical control mode. Deformation even damage happening to the electric winch in the obstacle removal process is avoided; the structure is simple, and safety is guaranteed; the electric winch device can be reliably fixed to the pair of vehicle frame girders of the vehicle and quickly carried by the vehicle.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting vehicles, and in particular relates to an electric winch device of a fire-fighting vehicle. Background technique [0002] Obstacles are unavoidable on the roads that the public security fire department dispatches to rescue and rescue the disaster relief station. , etc., if not limited to enumerating this obstacle can not be dragged away in time, it will affect the passage of vehicles and delay the precious time of emergency rescue and disaster relief. Similarly, if there is no dedicated vehicle-mounted obstacle removal device, the only way to remove obstacles is to use manpower. On the one hand, the efficiency of obstacle removal is low, and on the other hand, the labor intensity of the obstacle removal personnel is high. On the other hand, it will also delay the timing of rescue and disaster relief. . [0003] In the disclosed Chinese patent documents, the technical information of all obs...

CN201325365Y introduces "wrecker's front support splayed leg" and CN201736876U discloses "wrecker's tire supporting device" which is also used for clearing obstacles of illegally parked vehicles on the road, that is, its objects are all illegally parked vehicles or accident vehicles , as described in CN2255388Y, this obstacle removal device is not suitable for the removal of the piles combined with the foundation or the obstacles that have a large mass and can be pulled by ropes

This type of obstacle removal device can also be seen in the published Chinese patent documents, typically such as the "wrecker winch automatic control device" recommended by the authorized announcement number CN201626792U. This patent solution can objectively fulfill the description in paragraph 0005 of its specification However, looking at paragraph 0009 of the patent specification and its drawings, it is not difficult to find the following shortcomings: first, because the entire winch is in a horizontal cantilever state, the stability is difficult to guarantee and it is easy to cause damage; second, due to The electrical control device is composed of an electronic counter, a sensor, two wiring harnesses, a hydraulic control box, etc., so the overall structure is relatively complicated; third, because the patent does not provide the relevant components and related content that can be connected to the vehicle, it is difficult for those skilled in the art to It is not enough to obtain the inspiration to equip the whole device on the fire fighting vehicle according to the instruction of its manual

The "wrecker vehicle for roads" provided by the authorized announcement number CN203020152U gives the inspiration of installing the whole device such as a winch and a rope guide on the vehicle (the patent is called the wrecker body) through a bracket, but does not give a simplified electrical Inspiration from the controls
