Description

Technical Field

[0001] The utility model belongs to the technical field of crawler-type snow sweepers, and in particular relates to a crawler-type lower handrail structure for a snow sweeper. Background Art

[0002] A crawler snowplow is a highly efficient snow-clearing device. The working principle of a crawler snowplow generally involves a motor or engine providing power, which is transmitted to the working parts and the travel system through a worm gear drive or a belt drive. The collection device of the snowplow collects the snow into a cavity, which is then removed by a snow removal device. When the snow-throwing impeller rotates at high speed, the snow is thrown out by centrifugal force, thereby achieving continuous snow clearing. The lower armrest of the crawler snowplow provides the user with an additional support point, especially when operating on uneven or inclined ground, which helps to maintain the stability of the snowplow and the balance of the user. When the existing crawler snowplow armrest is in use, the armrest and the support frame of the crawler snowplow are fixed mechanisms. When operators of different heights hold and use the armrest, the armrest cannot be adjusted in height, which makes it inconvenient to use. For this reason, we propose a crawler lower armrest structure for snowplows. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a crawler-type lower handrail structure of a snowplow, comprising a snowplow 1, a support frame 2 being fixed to the inner top end of the snowplow 1, a handrail 3 being provided on the top end of the support frame 2, an adjustable height mechanism being provided between the handrail 3 and the support frame 2, a gripping anti-slip mechanism being provided on the surface of the handrail 3, and the adjustable height mechanism comprising: a connecting guide assembly, which is arranged at the bottom end of the handrail 3 and connected to the support frame 2; a limiting assembly, which is arranged on the inner side of the handrail 3 and connected to the support frame 2.

[0020] In this embodiment, preferably, the connecting guide assembly includes a connecting groove 100 provided at the bottom end of the armrest 3 , and the connecting groove 100 is sleeved and connected to the top end of the support frame 2 to facilitate adjustment of the height of the armrest 3 .

[0021] In this embodiment, preferably, a guide groove 200 and a guide rod 201 fixed inside the connecting groove 100 are formed at the top end of the supporting frame 2 , and the guide rod 201 is slidably connected to the guide groove 200 .

[0022] In this embodiment, preferably, the limiting assembly includes limiting grooves 300 equidistantly arranged on the inner side of the support frame 2 and a built-in groove 301 extending through one side of the inner wall of the connecting groove 100. A limiting rod 302 is arranged inside the built-in groove 301, and the limiting rod 302 is engaged with the limiting groove 300 to limit the adjusted position of the armrest 3.

[0023] In this embodiment, preferably, a through groove 400 and a fixed block 401 fixed inside the built-in groove 301 are opened through the surface of the limit rod 302, and a telescopic spring 402 is connected between the fixed block 401 and the through groove 400, which can drive the limit rod 302 to reset and pop out from the inside of the built-in groove 301.

[0024] In this embodiment, preferably, a pulling button 500 is provided on the inner side of the armrest 3 and is embedded in the inner side of the built-in groove 301 and fixedly connected to the limiting rod 302 , so as to facilitate pulling the limiting rod 302 into the inner side of the built-in groove 301 .

[0025] In this embodiment, preferably, the gripping anti-slip mechanism includes a rubber ring 600 sleeved on the surface of the armrest 3 and anti-slip stripes 601 fixed at equal distances on the surface of the rubber ring 600, which can play an anti-slip role when gripping the armrest 3.

[0026] The working principle and use process of the present invention: When the height of the armrest 3 needs to be adjusted, the pull button 500 is first pulled to drive the limit rod 302 to withdraw from the inside of the limit groove 300 and retract into the inside of the built-in groove 301, and drive the through groove 400 to slide on the surface of the fixed block 401 to squeeze the telescopic spring 402 to deform, so as to release the positioning of the armrest 3, and then lift the armrest 3 upward to make it slide on the surface of the support frame 2 through the connecting groove 100, and at the same time drive the guide rod 201 to slide inside the guide groove 200 to play a moving guide role. When the armrest 3 is moved to a suitable height After the height of the armrest 3 is adjusted, stop pulling the armrest 3 so that the guide rod 201 is temporarily positioned inside the guide groove 200, and the built-in groove 301 is aligned with the limit groove 300 of the corresponding height. Then release the pulling button 500, so that the through groove 400 is reset and slid on the surface of the fixed block 401 under the action of the telescopic spring 402, and at the same time drive the limit rod 302 to pop out from the inside of the built-in groove 301 and snap into the inside of the limit groove 300, so that the height of the armrest 3 can be positioned and the adjustment work is completed. Subsequently, when holding and using the armrest 3, the rubber ring 600 and the anti-slip stripe 601 can play a role in gripping and preventing slipping.
