Technical Field

[0001] The utility model relates to the field of rail maintenance, in particular to a positioning device for installing a switch sleeper. Background Art

[0002] The switch sleeper is a special sleeper used on railway turnouts, mainly used at the turnout traction point. The turnout electrical conversion rod can be placed in the sleeper, which is beneficial to the maintenance operation of the large machine. When the quality of a switch sleeper declines after long-term use, it needs to be replaced in time. The existing replacement method is generally to mark the position of the switch sleeper to be replaced on the turnout, and then place the new switch sleeper at the marked position after the switch sleeper to be replaced is replaced. This method can easily lead to deviations in the position of the switch sleeper after replacement. After multiple switch sleepers are replaced, errors are likely to accumulate and increase, affecting the accuracy of the switch sleeper spacing and the accuracy of the operation of switch devices such as switches.

[0020] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0021] See attached Figure 1 and 2 The utility model discloses a positioning device for installing a switch sleeper, the main structure of which includes a fixing frame 2 connected to a fixed switch sleeper 1, the fixing frame 2 being connected to a fixed switch sleeper 1 that does not need to be replaced, the fixed switch sleeper 1 can be a switch sleeper adjacent to or spaced by several intervals from the switch sleeper 4 to be replaced, so that the position of the fixing frame 2 is more stable, which is convenient for the accuracy of the position limiting of the switch sleeper 4 to be replaced in the later stage. The fixing frame 2 is provided with a support rod 3, the support rod 3 extends laterally toward the switch sleeper 4 to be replaced, and a positioning rod 5 in contact with the switch sleeper 4 to be replaced is laterally slidably connected to the support rod 3. The setting of the positioning rod 5 can accurately mark the position of the switch sleeper 4 to be replaced, and the positioning rod 5 can be slid laterally to make it contact with the side of the switch sleeper 4 to be replaced before replacement. After replacement, the new switch sleeper only needs to contact with the positioning rod 5 to ensure the accuracy of the position of the switch sleeper before and after replacement, which greatly reduces the error before and after the switch sleeper is replaced. When the switch sleeper is replaced, the limit frame 6 can be slid downward to separate it from the support rod 3, and then the support rod 3 can be rotated horizontally to make the support rod 3 and the positioning rod 5 leave the working position, so as to avoid interference with the replacement and installation of the switch sleeper, thereby ensuring the convenience and efficiency of the replacement and installation of the switch sleeper. After replacement, the support rod 3 can be rotated in the opposite direction and the limit frame 6 can be slid upward. An adjusting rod 7 is rotatably connected to the support rod 3 through a bearing, and the adjusting rod 7 passes through the positioning rod 5 and is threadedly connected thereto. When positioning the position of the switch sleeper, the structure only needs to rotate the adjusting rod 7 to drive the positioning rod 5 to slide under the action of the threaded connection until it contacts the side of the switch sleeper 4 to be replaced. The structure is simple and easy to operate, which ensures the accuracy and convenience of positioning the switch sleeper.

[0022] Preferably, the positioning rod 5 is rotatably connected to a roller 8, and the roller 8 is in rolling contact with the side of the switch sleeper 4 to be replaced. Such a structure enables the limit frame to rotate more smoothly relative to the switch sleeper 4 to be replaced under the action of the roller 8 when the support rod 3 rotates, thereby reducing the relative friction between the two and ensuring the convenience and smoothness of the rotation of the support rod 3.

[0023] Preferably, a circular frame 9 is welded or integrally formed on the top of the positioning rod 5, and the circular frame 9 is slidably sleeved on the outside of the support rod 3. The adjusting rod 7 passes through the circular frame 9 and is threadedly connected with it. The setting of the circular frame 9 makes the sliding structure of the positioning rod 5 relative to the support rod 3 more stable, and the positioning rod 5 is not prone to tilting or shaking during the positioning process, thereby ensuring the accuracy of the positioning of the switch sleeper.

[0024] Preferably, see Attachment Figure 3 A pipe sleeve 10 is welded or bolted on the fixing frame 2, and the top of the pipe sleeve 10 is open. The limit frame 6 is vertically slidably connected in the pipe sleeve 10. The setting of the pipe sleeve 10 makes the up and down sliding structure of the limit frame 6 more stable, ensuring the accuracy of the position limiting of the support rod 3. A compression spring 11 is provided between the bottom of the limit frame 6 and the bottom of the pipe sleeve 10. Such a structure can compress the compression spring 11 when the limit frame 6 slides downward, so that when the support rod 3 needs to be limited again in the later stage, it is only necessary to loosen the limit frame 6, and the limit frame 6 can automatically slide upward and reset under the elastic force of the compression spring 11, and maintain the limiting state of the support rod 3. The structure is simple, the operation is convenient, and the convenience of the limiting operation of the support rod 3 is improved.

[0025] Preferably, see Attachment Figure 4 The top of the limit frame 6 is U-shaped, and the support rod 3 is in contact with both sides of the U-shaped interior. The U-shaped structure enables the limit frame 6 to accurately get stuck on both sides of the support rod 3 after sliding upward, thereby preventing the support rod 3 from continuing to rotate, and the limiting effect on the position of the support rod 3 is more accurate and stable. A pedal 12 is welded or bolted on one side of the limit frame 6. The setting of the pedal 12 makes it only necessary to step on the pedal 12 with your foot when sliding the limit frame 6 downward, thereby further simplifying the operation steps of the limit frame 6.

[0026] Preferably, the fixing frame 2 is an inverted U-shape which is sleeved on both sides of the fixed switch sleeper 1. The inverted U-shaped structure allows the fixing frame 2 to only need to be sleeved on both sides when connected to the fixed switch sleeper 1, and the connection and fixation with the fixed switch sleeper 1 is more convenient. Both ends of the inverted U-shaped bottom are provided with cone heads 13, and the bottom of the cone head 13 is a pointed structure. After the fixing frame 2 is sleeved on the side of the fixed switch sleeper 1 and continued to be pressed down, the cone head 13 makes it easier for the fixing frame 2 to pass through the ballast below and enter the ground for fixation, so that the fixing operation of the fixing frame 2 and the fixed switch sleeper 1 is more convenient and accurate.

[0027] Working principle: the structure of the utility model comprises a fixing frame 2 connected with a fixed switch sleeper 1, a support rod 3 is arranged on the fixing frame 2, a positioning rod 5 is connected with the support rod 3 along a transverse sliding manner, the positioning rod 5 contacts the side of the switch sleeper 4 to be replaced, an adjusting rod 7 is rotatably connected with the support rod 3, the adjusting rod 7 penetrates the positioning rod 5 and is connected with a thread, such a structure rotates the adjusting rod 7 before replacement so that the positioning rod 5 slides along the support rod 3 until it contacts the side of the switch sleeper 4 to be replaced, thereby realizing accurate identification of the position of the switch sleeper 4 to be replaced, and after the new switch sleeper is replaced, it only needs to make its side contact with the positioning rod 5 again, which greatly reduces the position error before and after the switch sleeper is replaced, ensures the accuracy of the switch sleeper spacing, and ensures When the tie rod 3 is replaced, the cam 6 is in the state of being easily broken, and the cam 6 is easily broken, so that the cam 6 can easily be broken.
