Description

  The present invention relates to a tire tire chain winding induction device for efficiently and easily winding a tire chain on a large tire of a vehicle such as a dozer in order to obtain an anti-slip effect due to road freezing, snow accumulation, or the like.

  Every winter, there are frequent crisis situations where the running vehicle slips or falls out of control due to freezing on the road or snow accumulation, and the vehicle stops running.

  It can be said that the above-mentioned situation is mostly caused by a tire idling phenomenon caused by the frictional force being extremely reduced due to freezing of the tire contact surface of the vehicle on the road and snow accumulation.

  There are almost three methods that are actually used to prevent the tire spinning phenomenon. First, a method of developing a so-called studless tire to minimize the phenomenon of frictional force even when the tire itself is cooled, frozen on the road, etc., second, a method of fixing spike-like metal fittings on the tire contact surface, A method has been devised in which a tire chain-like metal fitting is wound around.

  The present invention provides a third method of winding a tire chain to cover a large tire ground contact surface.

  In order to cover the entire large tire contact surface with a tire chain, there is a possibility that it will be a cramping and dangerous work such as rotating the tire itself once, but if you prepare two types of tires for winter and non-winter, Before attaching the tire for winter, that is, the work of winding the tire chain around the tire alone is not so difficult, and it is only necessary to attach the tire to the vehicle after winding.

  However, considering the cost-effectiveness, it is clear that two sets of tires are required for one vehicle, resulting in an excessive cost burden, and it is necessary to secure a storage place for unused tires. It's not an effective measure.

  Accordingly, it is expected that more methods of winding a tire chain around a tire used throughout the year are expected, and the present invention also has an idea of a device for winding a tire chain in the state of a vehicle-installed tire.

  The biggest challenge for winding a tire chain around a tire that is already mounted on a vehicle, particularly a heavy weight dozer, etc., is that the tire itself has a very large pressing force on the ground due to the heavy weight of the vehicle. It is difficult and dangerous for a person to lift up the vicinity of a tire using a machine such as a jack for a normal vehicle and wind a tire chain.

  Therefore, a construction method has been devised in which a tire chain is wound around while being grounded, instead of creating a state in which the tire itself is detached from the ground with a jack or the like.

  In Patent No. 2834428, a tire chain is placed on the upper part of the tire other than the ground contact surface, and the tire chain is half-rotated by being clamped by springs at appropriate points on both ends of the tire chain, and the entire tire chain is caused by the contraction clamping force of the spring Has a method of connecting both ends of the tire chain by utilizing the fact that it is difficult to separate from the tire and fall.

  In addition, in the utility model registration number 3027195, when a tire chain is wound around a double tire such as a bus or a truck, after a pair of U-shaped sandwiching frames are sandwiched between tires, the U-shaped sandwiching frame The present invention has a device in which both ends of a tire chain are connected by hooking the tip of a tire chain on a hook attached to the outside and driving the tire once.

  By the way, tire chain winding work is often carried out when the road is frozen or snowy, and workers must work under adverse conditions such as coldness and instability of the feet due to freezing, and even a tight system under the vehicle It can be said that it is an inefficient work with more and more difficulty if it is a work at.

  Under the condition of road freezing and snow accumulation, the problem of Patent No. 2934428 requires the work of removing snow adhering to the tire itself to which snow is adhering, and then placing the tire chain on the tire ground contact surface, The both ends of the spring that has contraction force on both the outer and inner sides of the tire are hooked in place on the tire chain, but it is balanced so that the mounted tire chain does not come off the tire ground contact surface due to the contraction force of the mounted spring. It must be engaged with a certain force while taking. Moreover, if one person tries to work alone, it is impossible to apply the springs to both sides of the tire at the same time, and there is a risk that the tire chain will be guided to the side where the spring is first attached.

  Next, the tire chain attachment work according to utility model registration number 3027195 must first be fitted to the tire ground contact surface with a U-shaped sandwiching frame, but the U-shaped sandwiching frame is fitted when the road surface freezes or snowfall. Because of its elasticity, which uses a U-shaped characteristic that is normally open on one side, the ground contact surface of the tire should be clamped at a constant pressure. The elasticity of the quality tire is also reduced, and the pressure on the U-shaped sandwiching frame itself is weakened so that it does not come off the tire while the tire is rotated one revolution while bearing the weight of the tire chain at a constant pressure. For this purpose, it is necessary to make adjustments such as tightening the U-shaped sandwiching frame after fitting it to the tire ground contact surface.

  Moreover, in both devices, the spring hooking, the hooking of the tire chain, and the connection of both ends of the tire chain in the final stage are all cramped work under the vehicle, and it is still more difficult work under road freezing and snow conditions.

  The present invention provides a device capable of shortening the work under the vehicle and freeing a tire chain even with a very large tire such as a dozer in a road freezing or snowy condition. .

    The object of the present invention is to wind up the tire chain while keeping the ground contact without lifting the large tire away from the ground contact surface.

  As a work method of trying to wind a non-slip tire chain around a large tire such as a dozer, even if you lift the vehicle with a jack or the like to wind the large tire tire chain, let's raise it while withstanding the weight of the vehicle such as a dozer However, it is difficult to lift a normal vehicle jack, and it can be said that it is dangerous for workers under the vehicle.

  The U-shaped guide part to guide the winding of the tire chain is fitted and joined to the tire ground contact surface. However, since the rubber tire has elasticity, the physical force such as one rotation of the tire can be achieved by only pressing the U-shaped guide part itself. There is a possibility that it will come off when the target force is applied.

  Therefore, by providing a tapered tire pressing portion positioned perpendicularly to one of the plate-like short portions located at both ends of the U-shaped guiding portion, the U-shaped guiding portion is pressed against the outer surface of the tire. It is possible to more firmly fit and clamp.

  Next, the left and right connecting parts at the end of the tire chain are connected to the closed hook of the U-shaped guide part and two detachable shackles. Can be easily implemented without need.

  When attaching a shackle with a tire chain connected to a closed hook located on the outside / inside of the tire, the shackle can be attached very easily by using a shackle designed for connection instead of directly connecting the tire chain. it can.

  At this stage, by starting the vehicle such as a dozer and rotating the tire once, the tire chain guided by the U-shaped guiding portion also rotates once, and the U-shaped guiding portion is removed from the tire ground contact surface. The tire chain winding work is completed by removing the tire chain from the shackle and connecting the tire chain head and tire chain tail.

  First, since the present invention does not employ a method of lifting a large vehicle such as a dozer with a jack or the like, no extra and dangerous work is required to enter under the vehicle.

  In addition, the work execution time for winding the tire chain around the tire ground contact surface can minimize the work time in the cold environment under road freezing and snow conditions and under the vehicle such as a dozer.

  After fitting the tire chain winding induction device to the tire ground contact surface, the tire chain winding induction device presses the tire side that is in contact with the tire pressing portion located on one side of the tire chain winding induction device. Since there is no risk of detachment when winding the chain, the next operation can be carried out smoothly.

  As a method of connecting the tire chain to the tire chain winding induction device, if the tire chain is directly attached to the closing hooks provided on both sides of the tire chain winding induction device, the tire chain is held in one hand and the tire chain joint is connected. It takes a certain amount of work time to connect with the hook that is closed, and under the large vehicle such as a dozer, it will be forced to withstand the cold and cruel work, but with a shackle in the present invention Therefore, after attaching the tire chain to the shackle at another work place, the connecting work is completed simply by inserting the shackle into the closing hook.

  Next, when the tire is rotated once and the tire chain itself wraps around the tire grounding surface, the tire chain winding induction device is removed, and finally the tire chain end is connected to the end of the tire chain. Is completed.

  That is, by using the tire chain winding induction device of the present invention as described above, it can be carried out safely and smoothly and efficiently, that is, the tire tire chain winding of a vehicle such as an excellent dozer to ensure prevention of tire slippage. It is possible to complete the wear.

  As described above, according to the present invention, a general person other than the contractor can easily and smoothly perform the work of winding the tire chain around the tire of a large vehicle such as a dozer, and the work process under the vehicle. Therefore, it is intended to provide a tire chain winding induction device that is minimized and excellent in safety.
