Abstract
Description
A railcar protection device Technical Field
[0001] This utility model relates to the field of rail vehicles, and more specifically, to a rail vehicle protection device. Background Technology
[0002] With the continuous expansion of the railway network and the increase in operating mileage, the tasks of railway line construction, daily inspection, maintenance, and emergency rescue are becoming increasingly heavy. Traditional manual operation and simple tools and equipment can no longer meet the requirements of completing these tasks efficiently and safely. There is a need to design a special vehicle that can travel on the track and has multiple functions to carry personnel, tools, and materials to the work site quickly and carry out relevant operations. The railcar has emerged to meet this need.
[0003] During operation, the wheels of a railcar generate heat through friction. This heat not only affects the wheels themselves but also the track. The high temperature of the wheels raises the surface temperature of the track, causing changes in the properties of the track materials and accelerating track wear and deformation. At the same time, heat transfer between the wheels and the track can also cause thermal expansion and contraction of the track, changing its geometry and affecting its smoothness, which in turn affects the operational stability and safety of the railcar.
[0004] Therefore, we have made improvements to this and proposed a railcar protection device. Summary of the Invention
[0005] In order to achieve the above-mentioned objectives, this utility model provides a railcar protection device to solve the above problems.
[0006] This utility model specifically includes:
[0007] The heat sink has a wheel fixedly connected to one side. Its diameter is larger than that of the wheel, and the part extending beyond the wheel has several heat dissipation holes arranged in a ring.
[0008] A rotating shaft with wind shields connected through both ends, and several guide plates are hinged to the inner wall of the wind shields;
[0009] A protective cover is fixedly connected to the wind shield near the wheel surface, and several guide grooves are provided at the top inside the wind shield.
[0010] Preferably, the wind shield contracts from the side closest to the wheel to the other side, forming a variable diameter shape, and the contracted side is connected to an air supply pipe.
[0011] Preferably, the gas delivery pipe has multiple sections, and the other end is located directly above the protective cover and passes through the protective cover to communicate with the guide channel.
[0012] Preferably, a heat exchange plate is fixedly connected to the heat dissipation plate away from the wheel surface, and the heat exchange plate is spirally arranged from the center outward along the heat dissipation plate.
[0013] Preferably, a dual-axis motor is fixedly connected to the middle of the rotating shaft, and the rotating shaft passes through the heat exchange plate and the heat sink and is rotatably connected to the guide plate located in the middle.
[0014] Preferably, the two ends of the rotating shaft are also connected to support seats, and a hopper is fixedly connected to the upper surface of the support seat.
[0015] Preferably, the protective cover is arc-shaped with an opening facing downwards, and has the same diameter as the heat sink and is fixedly connected to the surface of the largest diameter of the shroud.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] The rotating wheel generates wind, which enters the interior of the shroud. The collected air is transported along the guide plate. Since the shroud is designed to contract, the wind speed is increased. The wind speed increases closer to the contraction point until it reaches the air supply pipe. The air in the air supply pipe enters the guide groove in the protective cover and is discharged along the guide groove. After being discharged, it blows the rotating wheel to dissipate heat. In addition, a heat exchange plate is fixedly connected to one side of the wheel and a heat exchange plate is fixedly connected to the heat exchange plate for heat exchange. At the same time, the heat exchange plate is designed in a spiral shape to increase the heat exchange area and accelerate heat dissipation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0030] As in the background art, the high temperature of the wheel 102 will cause the temperature of the track surface to rise, resulting in changes in the properties of the track material and accelerating the wear and deformation of the track.
[0031] To solve this technical problem, this utility model provides a railcar protection device, which is used to dissipate heat from the wheels 102 that generate heat through friction.
[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0035] As shown in Figures 1 to 5, a railcar protection device includes:
[0036] The heat sink 101 has a wheel 102 fixedly connected to one side. The diameter of the heat sink 101 is larger than that of the wheel 102, and the portion of the heat sink 101 extending beyond the wheel 102 has several heat dissipation holes 103 arranged in a ring.
[0037] A rotating shaft 104 has a wind shield 105 connected through both ends, and several guide plates 106 are hinged to the inner wall of the wind shield 105.
[0038] A protective cover 107 is fixedly connected to the side of the shroud 105 near the wheel 102. Several guide grooves 108 are provided at the top inside the shroud 105. The air supply pipe 201 has multiple sections, with one end located directly above the protective cover 107 and passing through the protective cover 107 to communicate with the guide grooves 108. The shroud 105 contracts in a variable diameter shape from the side near the wheel 102 to the other side, and the contracted side is connected to the air supply pipe 201. A heat exchange plate 401 is fixedly connected to the side of the heat dissipation plate 101 away from the wheel 102. The heat exchange plate 401 extends outward from the center in a spiral shape.
[0039] During the heat dissipation process, the rotation of the wheel 102 generates wind, which enters the interior of the shroud 105. The collected air is transported along the guide plate 106. Since the shroud 105 is designed to be constricted, the wind speed can be increased. The wind speed increases closer to the constriction point until it reaches the air supply pipe 201. The air in the air supply pipe 201 enters the guide groove 108 in the protective cover 107 and is discharged along the guide groove 108. After being discharged, it blows the rotating wheel 102 to achieve heat dissipation of the wheel 102. In addition, the heat exchange plate 401 fixedly connected to one side of the wheel 102 and the heat exchange plate 401 fixedly connected to the heat exchange plate 101 exchange heat. At the same time, the heat exchange plate 401 is designed to be spiral to increase the heat exchange area and accelerate heat dissipation.
[0040] A dual-shaft motor 501 is fixedly connected to the middle of the rotating shaft 104. The rotating shaft 104 passes through the heat exchange plate 401 and the heat sink 101 and is rotatably connected to the guide plate 106 located in the middle.
[0041] A dual-axis motor 501 fixedly connected to the middle of the rotating shaft 104 is used to drive the rotating shaft 104 to rotate. The rotation of the rotating shaft 104 drives the wheel 102 to rotate. The rotating shaft 104 passes through the heat exchange plate 401, the heat sink 101 and the guide plate 106 located in the middle and is fixedly connected so that it can drive the baffle and the protective cover 107 for support during the rotation process.
[0042] The two ends of the rotating shaft 104 are also connected to the support base 601, and the upper surface of the support base 601 is fixedly connected to the hopper 602.
[0043] The support base 601, which is connected through both ends of the rotating shaft 104, is used to support the hopper 602. The hopper 602, which is fixedly connected to the upper surface of the support base 601, is used for transportation and is used in some cases for railways and construction sites.
[0044] The protective cover 107 is arc-shaped with its opening facing downwards, and is of the same diameter as the heat sink 101 and is fixedly connected to the largest diameter surface of the fan cover 105.
[0045] The protective cover 107 is arc-shaped with the opening facing downwards so that the generated airflow can be fully blown out along the wheel 102 for heat dissipation. The protective cover 107 can also protect the wheel 102 from external interference.
[0046] The usage process of the railcar protection device provided by this utility model is as follows:
[0047] During the heat dissipation process, the rotation of the wheel 102 generates wind, which enters the interior of the shroud 105. The collected air is transported along the guide plate 106. Since the shroud 105 is designed to be constricted, the wind speed can be increased. The wind speed increases closer to the constriction point until it reaches the air supply pipe 201. The air in the air supply pipe 201 enters the guide groove 108 in the protective cover 107 and is discharged along the guide groove 108. After being discharged, it blows the rotating wheel 102 to achieve heat dissipation of the wheel 102. In addition, the heat exchange plate 401 fixedly connected to one side of the wheel 102 and the heat exchange plate 401 fixedly connected to the heat exchange plate 101 exchange heat. At the same time, the heat exchange plate 401 is designed to be spiral to increase the heat exchange area and accelerate heat dissipation.
