[0029] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0030] like Figures 1 to 6 As shown, the straddle-type monorail running surface obstacle clearing device is a running surface obstacle clearing device for severe rain, snow and freezing climates; the obstacle clearing device is installed at both ends of the vehicle to ensure that when the vehicle is running, the obstacle clearing device always works in front of the tire, sweeping rain, snow and thin ice out of the track beam running surface, providing protection for the rolling of the rear tires to avoid slipping.

[0031] The obstacle clearing device 2 includes an obstacle clearing frame 4, an execution frame 7, an obstacle clearing brush 8, a downward pressure driving module and a control module 3 for controlling the lifting working state of the execution frame. The obstacle clearing frame is installed at the end of the monorail vehicle through a connecting frame, the obstacle clearing brush is arranged below the execution frame, the execution frame is arranged below the obstacle clearing frame, and the downward pressure driving module is arranged between the obstacle clearing frame and the execution frame bracket.

[0032] The end of the monorail vehicle is provided with a body end crushing pipe 1, and the connecting frame is connected to the body end crushing pipe. Preferably, the connecting frame includes a clamp 5 and a connecting plate 6, the clamp is connected to the body end crushing pipe, the inner side of the clamp is connected to the edge of the obstacle clearing frame, and the outer side of the clamp is connected to the vehicle frame through the connecting plate 6. The device is integrated, compact, and easy to arrange and install.

[0033] The obstacle-clearing brush 8 includes a front brush and a rear brush arranged side by side, and both the front brush and the rear brush are V-shaped brush structures with a pointed tip in the middle. The obstacle-clearing device is contact-type through the brush at the bottom of the device; the device is controlled by a manual hydraulic mechanism or an automatic hydraulic control module in the vehicle, so that the obstacle-clearing device at the head end of the forward direction is always working and the obstacle-clearing device at the tail end is always raised; at the same time, relying on the downward driving module and the guide module, the device can always effectively clear obstacles on the running surface.

[0034] A set of vertical guide modules 9 is provided between the obstacle clearing frame and the execution frame. Preferably, the guide module is fixed on the obstacle clearing frame, and the guide module includes a guide column and a linear bearing, and the lower end of the guide column is connected to the execution frame. The execution frame includes a front frame and a rear frame, and the front frame and the rear frame are connected by a connecting frame 701. The lower part of the front frame and the rear frame are both installed with obstacle clearing brushes, and the lower end of the guide column is connected to the connecting frame; the structure is compact and the operation is stable and reliable.

[0035] The downward driving module is a gas spring 12, the upper end of which is hingedly connected to the obstacle clearing frame, and the lower end of which is hingedly connected to the connecting frame. The gas springs are symmetrically arranged in a pair, and the pair of gas springs are arranged in an eight-shaped shape. The execution unit is always pressed by the gas spring, and the brush in the execution unit is always in contact with the running surface of the track beam. The gas spring can effectively compensate for the displacement loss caused by the wear of the brush and can effectively reduce the vibration of the main structure.

[0036] The control module 3 includes a control hydraulic cylinder 10 and a control link structure 11. The hydraulic cylinder is fixed on the obstacle removal frame. The control link structure is arranged between the obstacle removal frame and the execution frame. The piston rod of the hydraulic cylinder is associated with the upper end of the control link structure.

[0037] Preferably, the control link structure includes a driving rod 1103, a connecting rod 1102 and a lifting connecting rod 1101, wherein the driving rod is a bending rod, the bending part of the driving rod is hingedly connected to a seat body provided on the obstacle clearance frame, the lifting connecting rod is connected to the execution frame, the lifting connecting rod and the driven end of the driving rod are connected through a connecting rod, and the end of the piston rod is provided with a roller 1001 for driving the driving end of the driving rod.

[0038] The control module of the present invention has a compact structure and an integrated arrangement, which is convenient for arrangement and installation. When not in use, the hydraulic cylinder of the control module drives the connecting rod structure to lift the execution frame, and the brush does not contact the running surface, which makes the control simple.

[0039] The obstacle clearing device of the present invention is arranged on the crush pipe at the end of the vehicle body, so as to ensure that when the vehicle is running, the obstacle clearing device always works in front of the tire, sweeps rain, snow and thin ice out of the running surface of the track beam, has a good effect of clearing rain, snow and thin ice, provides protection for the rolling of the rear tires, and avoids slipping; the integrated arrangement has a compact structure.

[0040] Preferred embodiments of the present invention are:

[0041] The present invention discloses a running surface obstacle clearing device for severe rainy, snowy and freezing weather, comprising an obstacle clearing frame, a downward pressure drive module, a guide module, an execution unit and a control module; cylindrical clamps are used at both ends of the obstacle clearing frame to clamp the obstacle clearing device on the round tube of the crushing tube at the end of the vehicle body, so that the main body of the obstacle clearing device can be effectively fixed and integrated.

[0042] The obstacle clearing frame of the obstacle clearing device provides an installation interface for the downward drive module, the guide module, and the control module; further, the downward drive module of the obstacle clearing device is composed of two gas springs, and the two ends of the gas spring are respectively connected to the main beam and the execution unit, so that during the cleaning process, one end of the obstacle clearing frame is fixed, the execution unit is always pressed by the gas spring, and the brush in the execution unit is always in contact with the running surface of the track beam. The gas spring can effectively compensate for the displacement loss caused by brush wear and can effectively reduce vibration for the main structure. When the end brush of the obstacle clearing device encounters resistance in the forward direction and bounces up, the gas spring can effectively stop it, and always maintain an effective cleaning effect.

[0043] The guide module of the obstacle removal device consists of a linear bearing, a guide column, a dust cover and a dust cloth. Among them, the linear bearing is installed on the obstacle removal frame through the bearing seat, and the bottom of the guide column is connected to the actuator bracket of the actuator unit through a thread. The guide column shuttles in the linear bearing, and a step is set on the top of the guide column to prevent it from falling off. The upper part of the guide column is dustproof with a dust cover, and the lower part is a flexible dust cloth that moves up and down with the actuator unit to achieve a dust-proof effect. The four guide columns can achieve synchronous up and down movement. When encountering special working conditions such as bumpy roads and climbing, the actuator unit can effectively rise when the force on the end of the brush is greater than the rated pressure of the gas spring. When the force on the end of the brush is reduced, it can effectively descend. The guide module cooperates with the gas spring to effectively ensure that the pressure of the brush on the running surface is constant.

[0044] The downward drive module, guide module and execution unit can achieve secondary vibration reduction. Since the vehicle is always a dynamic process when running on the running surface, the obstacle removal device is also in a dynamic balance process to achieve a stable obstacle removal function. When the force on the end of the brush is not equal to the force of the gas spring, the brush will deform first to compensate for the force difference. When the compensation cannot be met, the gas spring will further compensate through telescopic action and be in a state of dynamic balance. This will fully protect the guide mechanism and the obstacle removal frame to avoid impact.

[0045] The brushes of the obstacle clearing device are arranged in a V shape, with the tip always pointing in the direction of the vehicle's movement. When the vehicle is running, the obstacle clearing device at the front end works, with the working V-shaped tip of the brush pointing in the forward direction, and the obstacle clearing device at the rear end rises; when the vehicle moves in the opposite direction, the obstacle clearing device at the other end is raised, and the obstacle clearing device at the forward end is lowered, always tending to push obstacles to both sides.

[0046] The control module controls the lifting and lowering of the actuator unit outside the vehicle through the hydraulic device inside the vehicle. The control module is composed of the hydraulic mechanism inside the vehicle, the hydraulic cylinder outside the vehicle, and the steel wire rope assembly outside the vehicle. When the pressure is released, the hydraulic cylinder at the end of the control module is in an extended state, the steel wire rope is loose, the guide column can move up and down freely, and the obstacle removal device is in a working state; when the pressure relief valve in the vehicle is closed and the hand-cranked hydraulic pump in the vehicle is reciprocating, the hydraulic cylinder drives the steel wire rope to rise, lifts the brush, and leaves the running surface, and no longer performs the obstacle removal operation; its control module also uses other lifting drive mechanisms.

[0047] The above is only an explanation of the preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0048] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
