DETAILED DESCRIPTION

[0023] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of protection of the present application is not limited by the specific embodiments.

[0024] Unless otherwise explicitly indicated, in the entire specification and claims, the term "comprise" or its variants such as "contain" or "include" and the like will be understood to include the stated element or component without excluding the presence of other elements or components.

[0025] As shown in Figures 1 to 5 According to an embodiment of the present application, an ice breaking machine damping obstacle-crossing device comprises an ice breaking machine frame 4 and a damping obstacle-crossing mechanism 1, a protection mechanism 2 and a damping mechanism 3 installed on the ice breaking machine frame 4.

[0026] The front ice breaking wheel 5 and the rear ice breaking wheel 6 are installed below the ice breaking machine frame 4 and can be used to break ice and clean snow on the road surface. The front ice breaking wheel 5 is arranged in front of the driving direction and has ice breaking teeth arranged in the axial direction. The rear ice breaking wheel 6 is arranged behind the driving direction and can be arranged as an ice breaking wheel or a cleaning wheel brush according to the road surface condition.

[0027] The cross section of the ice breaking machine frame 4 is in a trapezoidal structure. The two ends of the long side of the bottom are rotatably connected to one end of the base of the front ice breaking wheel 5 and the rear ice breaking wheel 6 respectively. The two ends of the short side of the top are connected to the other end of the base of the front ice breaking wheel 5 and the rear ice breaking wheel 6 through the damping obstacle-crossing mechanism 1 respectively.

[0028] The damping obstacle-crossing mechanism 1 is a mechanical structure that can freely stretch and contract under external force. The damping obstacle-crossing mechanism 1 comprises an air cylinder 103 and a spring 104 arranged outside the air cylinder 103. The air cylinder 103 can limit the travel route of the front ice breaking wheel 5 and the rear ice breaking wheel 6 and ensure that the movement trajectory is controllable during use. The spring 104 can provide downward pressure to the front ice breaking wheel 5 and the rear ice breaking wheel 6.

[0029] As shown in Figures 2 to 3As shown, the upper and lower sides of the cylinder 103 are respectively provided with an upper spring cover 102 and a lower spring cover 105, which are used to connect the two ends of the spring 104 and bear the pressure of the spring 104. The upper and lower ends of the cylinder 103 are respectively provided with a joint bearing 101, which is respectively rotatably connected to the base of the front ice breaking wheel 5 and the rear ice breaking wheel 6 and the ice breaking frame 4, so that the cylinder 103 can rotate relative to the ice breaking frame 4 and the base when the cylinder 103 extends and retracts, preventing rigid damage and converting rigid connection into flexible connection, and leaving installation error to prevent damage to the cylinder in use due to error in welding installation.

[0030] The spring force of the spring 104 can determine the size of the self-weight borne and the ice breaking capacity of the ice breaking machine. If the spring force is too large, the ice breaking machine will cause serious damage to the road surface, and if the spring force is too small, the ice breaking machine cannot achieve the cleaning effect on the ice and snow road surface. Therefore, the selection of the spring is crucial to the ice breaking machine. The cylinder 103 can determine the height of the ice breaking machine profiled road surface and the use direction of the spring.

[0031] One end of the protection mechanism 2 is fixed to the middle of the top short side of the ice breaking frame 4, and the other end of the iron chain protection mechanism 2 is fixed to the end of the base of the front ice breaking wheel 5 and the rear ice breaking wheel 6 connected to the shock absorbing and obstacle crossing mechanism 1. The protection mechanism 2 is used to limit the longest extension distance of the shock absorbing and obstacle crossing mechanism 1 and protect the shock absorbing and obstacle crossing mechanism 1. The protection mechanism 2 preferably adopts an iron chain, which has the characteristics of flexible connection and can only limit the longest extension distance of the shock absorbing and obstacle crossing mechanism 1, without affecting the rotation and other movements of the shock absorbing and obstacle crossing mechanism 1. At the same time, there is no complex limiting structure, which is easy to maintain.

[0032] The long side of the lower part of the ice breaking frame 4 is connected to the base of the front ice breaking wheel 5 and the rear ice breaking wheel 6 through the shock absorbing mechanism 3. The shock absorbing mechanism 3 can profile the mechanism to slow down the vibration of the front ice breaking wheel 5 and the rear ice breaking wheel 6 in use, and can provide the rotation movement between the base of the front ice breaking wheel 5 and the rear ice breaking wheel 6 and the ice breaking frame 4.

[0033] As shown in the figure, Figures 4 to 5 The shock absorbing mechanism 3 includes a shock absorbing main block 302 and a shock absorbing bottom plate 303, and the shock absorbing main block 302 is arranged on the shock absorbing bottom plate 303. The shock absorbing bottom plate 303 is fixed to the ice breaking frame 4. The shock absorbing main block 302 is provided with a rotating hole, which is used to connect the base of the front ice breaking wheel 5 and the rear ice breaking wheel 6, so that the front ice breaking wheel 5 and the rear ice breaking wheel 6 can rotate relative to the ice breaking frame 4. A rubber shock absorbing sleeve 301 is arranged in the rotating hole of the shock absorbing main block 302, which can not only play a shock absorbing role, but also resist the long-term heavy impact of the equipment in operation by the physical properties of rubber. Preferably, it is made of wear-resistant rubber, which has the advantages of wear resistance, fatigue resistance and prolonging the service life of key components.

[0034] Further, a shock-absorbing limiting plate 304 is sleeved outside the shock-absorbing main block 302 to limit the position of the shock-absorbing main block 302.

[0035] The ice breaker shock-absorbing obstacle-crossing device of the utility model, through the innovative flexible connection design and shock-absorbing mechanism, significantly improves the operation efficiency and equipment reliability of the complex ice and snow road surface. Specifically: joint bearings are used to realize the rotary connection of the cylinder and the ice breaker frame, effectively compensate the welding installation error and avoid rigid damage; the linkage structure of the spring and the cylinder dynamically adjusts the ice breaking pressure and the profiling height, and takes into account the ice breaking capacity and the road surface protection; the iron chain protection mechanism limits the maximum elongation to prevent the spring from overloading and failing; the rubber sleeve in the shock-absorbing mechanism absorbs high-frequency vibration, and the limiting plate ensures controllable movement. The overall system realizes adaptive obstacle crossing, double shock absorption, modular design and multiple safety limiting, while ensuring the ice breaking efficiency, prolongs the service life of the equipment and reduces the maintenance cost, and is especially suitable for ice and snow removal operation in high-cold areas.

[0036] The foregoing description of the specific exemplary embodiments of the utility model is for the purpose of illustration and example. These descriptions are not intended to limit the utility model to the precise forms disclosed, and it is obvious that many changes and variations can be made according to the above-mentioned teaching. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the utility model and various different selections and changes.
