Description

Technical Field

[0001] The utility model belongs to the technical field of railway maintenance, and in particular relates to an electric rail grinding device. Background Art

[0002] In railway transportation, rails are the core components of train operation, and their status directly affects the safety and comfort of train operation. During use, rails will wear, crack, and other phenomena due to vehicle pressure, environmental factors, or material aging, which requires regular maintenance and repair. Electric rail grinders have therefore become one of the maintenance tools commonly used by railway engineering departments. They can effectively grind rail welds, uneven joints, rail side fat edges, rail surface weld repairs, and other problems, thereby restoring the performance of the rails. Electric rail grinders are usually composed of motors, grinding wheels, control systems, and other parts.

[0003] When the electric rail grinding device of the prior art is grinding the side of the rail, it is necessary to tilt the grinding device horizontally to facilitate the fit of the grinding wheel and the rail, but rail grinding is a relatively time-consuming and repetitive process, and the operator needs to support the grinding device flat so that it can be moved repeatedly for grinding. Long-term support and control can easily cause muscle soreness and is extremely physically demanding. The grinding wheel is also prone to tilt and vibrate, resulting in poor grinding quality. Utility Model Content

[0004] The utility model aims to provide an electric rail grinding device, which supports the control frame when the grinding device is horizontally placed to grind the rail by controlling the rotating rod, so as to facilitate the left and right sliding of the grinding device, and can also make the sliding seat fit with the rail sleeper by adjusting the screw rod, which is more flexible, avoids muscle soreness caused by long-term support and control of the grinding device, saves physical strength, and can also avoid the grinding wheel from tilting due to arm shaking, thereby improving the grinding quality.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The invention discloses an electric rail grinding device, comprising a control frame fixedly assembled on both sides of the grinding device, the control frame being configured as a straight rod for fixing mechanical parts and a cross rod for controlling movement, a rotating rod is symmetrically rotatably connected to the inner side of the straight rod of the control frame, two rotating rods are fixedly connected via a cross plate, a screw is rotatably screwed to the middle part of the cross plate, a sliding plate is rotatably connected to one end of the screw and is located below the cross plate, the top of the sliding plate is symmetrically fixedly connected to a limiting rod, the sliding plate is slidably connected to the rotating rod via the limiting rod, magnets for magnetic adsorption to the control frame are fixedly connected to both ends of the sliding plate, and a sliding seat is slidably connected to the bottom of the sliding plate.

[0007] The tops of both ends of the rotating rod are connected with sliding blocks in a damping sliding manner.

[0008] On one side of the sliding block, clamping blocks are symmetrically and fixedly connected.

[0009] On the outer wall of the control frame, friction grooves for the sliding and fitting of the clamping blocks are symmetrically formed.

[0010] The length of the sliding seat is less than that of the sliding plate.

[0011] On one side of the sliding seat, a pedal is rotationally assembled, and an extension plate is slidably connected to the inner wall of the pedal.

[0012] The technical effect achieved by the present utility model is as follows: By controlling the rotating rod, when the grinding device horizontally grinds the rail, it supports the control frame, facilitating the left - right sliding of the grinding device. Also, the sliding seat can be made to fit the track sleeper by adjusting the screw, which is relatively flexible.

[0018] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0019] As Figures 1 - 3As shown in the figure, an electric rail grinding device includes control frames 101 fixedly assembled on both sides of the grinding device 1. The control frames 101 are set as straight rods for fixing mechanical components and cross bars for controlling movement. The inner sides of the straight rods of the control frames 101 are symmetrically and rotatably connected with rotating rods 102. The two rotating rods 102 are fixedly connected by a cross plate 103. The tops of both ends of the rotating rods 102 are damping-slidably connected with sliding blocks 108. One side of each sliding block 108 is symmetrically fixedly connected with clamping blocks 109. Friction grooves 112 for the clamping blocks 109 to slide and fit are symmetrically formed on the outer walls of the control frames 101. A screw rod 104 is rotatably screwed in the middle of the cross plate 103. One end of the screw rod 104 is rotatably connected with a sliding plate 106 below the cross plate 103. The top of the sliding plate 106 is symmetrically fixedly connected with limiting rods 105. The sliding plate 106 is slidably connected with the rotating rods 102 through the limiting rods 105. Magnets 113 for magnetically adsorbing the control frames 101 are fixedly connected to both ends of the sliding plate 106. A sliding seat 107 is slidably connected to the bottom of the sliding plate 106. The length of the sliding seat 107 is less than that of the sliding plate 106. A pedal 110 is rotatably assembled on one side of the sliding seat 107. An extension plate 111 is slidably connected to the inner wall of the pedal 110.

[0020] According to the above structure, when the control frame 101 is placed horizontally, the grinding wheel grinding end of the grinding device 1 fits against the side of the track. Rotate the rotating rod 102 so that the magnet 113 no longer adsorbs to the control frame 101, making the rotating rod 102 perpendicular to the control frame 101. Then, by rotating the screw 104, the sliding plate 106 and the sliding seat 107 move downward, and the sliding seat 107 fits on the sleeper of the track. The limiting rod 105 can prevent the sliding plate 106 from rotating when the screw 104 rotates. Slide the sliding block 108 to drive the clamping block 109 to move, and the clamping block 109 engages with the friction groove 112 on the control frame 101. By increasing the friction, the separation of the clamping block 109 from the friction groove 112 is prevented. The clamping of the control frame 101 by the clamping block 109 can prevent the rotating rod 102 from continuing to rotate. The control frame 101 drives the grinding device 1, the rotating rod 102, etc. to move together. The sliding plate 106 slides on the top of the sliding seat 107. The cross plate 103, the screw 104, and the sliding plate 106 support the weight of the control frame 101. Rotate the pedal 110 to make it fit against the ground and slide out the extension plate 111. The stability of the sliding seat 107 can be enhanced by stepping on the extension plate 111 during the process of sliding the control frame 101. The technical effect achieved by the present utility model is that by controlling the rotating rod 102, when the grinding device 1 is placed horizontally to grind the rail, it supports the control frame 101, facilitating the left-right sliding of the grinding device 1. Also, by adjusting the screw 104, the sliding seat 107 can be made to fit against the track sleeper, which is relatively flexible. It can avoid muscle soreness caused by people holding and controlling the grinding device 1 for a long time, save physical strength, and also prevent the grinding wheel from tilting due to arm shaking, improving the grinding quality.

[0021] The working principle of the present utility model is as follows: When the control frame 101 is placed horizontally, the grinding wheel grinding end of the grinding device 1 fits against the side of the track. Rotate the rotating rod 102 so that the magnet 113 no longer adsorbs to the control frame 101, making the rotating rod 102 perpendicular to the control frame 101. Then, by rotating the screw 104, the sliding plate 106 and the sliding seat 107 move downward, and the sliding seat 107 fits on the sleeper of the track. The limiting rod 105 can prevent the sliding plate 106 from rotating when the screw 104 rotates. Slide the sliding block 108 to drive the clamping block 109 to move, and the clamping block 109 engages with the friction groove 112 on the control frame 101. By increasing the friction, the separation of the clamping block 109 from the friction groove 112 is prevented. The clamping of the control frame 101 by the clamping block 109 can prevent the rotating rod 102 from continuing to rotate. The control frame 101 drives the grinding device 1, the rotating rod 102, etc. to move together. The sliding plate 106 slides on the top of the sliding seat 107. The cross plate 103, the screw 104, and the sliding plate 106 support the weight of the control frame 101. Rotate the pedal 110 to make it fit against the ground and slide out the extension plate 111. The stability of the sliding seat 107 can be enhanced by stepping on the extension plate 111 during the process of sliding the control frame 101.

[0022] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
