Description

Technical Field

[0001] The utility model relates to the field of contact network geometric parameter measuring instruments, in particular to a mobile contact network geometric parameter measuring instrument. Background Art

[0002] The contact network geometry parameter measuring instrument is an instrument specially used to measure the geometry parameters of the contact network of electrified railways. It can measure the contact network's conductor height, pull-out value, locator slope, anchor joint, line turnout, superelevation, track gauge and red line parameters to ensure the safety and efficiency of railway operation. At present, the contact network geometry parameter measuring instrument consists of two parts: the measuring host and the measuring bracket.

[0003] When in use, the measuring bracket needs to be placed horizontally on the railway track, and then the legs at the bottom of the measuring bracket need to be in contact with the track. However, due to the lack of a certain lubrication structure between the legs at the bottom of the measuring bracket and the track, when the measuring bracket is pushed to move, the friction between the legs at the bottom of the measuring bracket and the track will generate friction, resulting in an increase in the pushing strength of the measuring bracket. When personnel adjust the position of the measuring bracket, the measuring bracket will move excessively due to excessive force or insufficient force due to insufficient movement of the measuring bracket. In order to solve the above problems, we propose a mobile contact network geometric parameter measuring instrument. Utility Model Content

[0004] The utility model aims to provide a mobile contact network geometric parameter measuring instrument, which has the advantages of being able to lubricate between the legs and the track to improve the movable sensitivity of the bracket.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a mobile contact network geometric parameter measuring instrument comprises a bracket, the bottom of the bracket is fixedly connected with a leg one, the bottom of the bracket is also provided with a leg two, the clamping surfaces of the leg one and the leg two are both installed with rotating balls; the leg two is penetrated by a threaded adjusting screw, the adjusting screw is rotatably supported on the bracket, and the top of the leg two is fixedly connected with a slider one, and the bottom of the bracket is provided with a slide groove one slidably connected with the slider one; the top of the bracket is provided with a mounting seat that can slide along its axial direction, the top of the mounting seat is provided with a connecting groove, the inside of the connecting groove is clamped with a connecting seat, the top of the connecting seat is fixedly connected with a measuring host, the surface of the connecting seat is provided with a positioning groove, the inside of the positioning groove is clamped with a positioning rod that slidably cooperates with the mounting seat, and the positioning rod passes through the side wall of the mounting seat and extends outward.

[0006] The above technical solution is adopted, by setting the support leg 1, support leg 2, balls, adjusting screw, slider 1 and slide groove 1, the two balls can be adjusted to contact the two sides of the track respectively, and the surface of the balls can be coated with lubricating oil, and when the bracket is pushed to move on the track, the balls can roll to remove the friction force, thereby reducing the friction resistance and improving the sensitivity of the bracket when moving. By setting the connecting seat, connecting groove, measuring host, positioning groove and positioning rod, the position of the measuring host can be limited, and when the measuring host is removed and installed again during the measurement process, it can be ensured that the measuring host is still in the original position, and there is no need to adjust the position of the measuring host again.

[0007] The utility model is further configured as follows: a spring is sleeved on the surface of the positioning rod, one end of the spring is fixedly connected to the mounting seat through a spring fixing piece, the other end of the spring is fixedly connected to a movable block through a spring fixing piece, and the movable block is fixedly sleeved on the positioning rod.

[0008] By adopting the above technical solution, through the setting of the spring, when the positioning rod and the movable block move, the spring will be pulled to extend and generate a rebound force; when the positioning rod loses the tension, the rebound force of the spring can pull the movable block and the positioning rod to reset; it should be noted that the rebound force of the spring is greater than the weight of the positioning rod and the movable block.

[0009] The utility model is further configured as follows: a receiving groove coaxial with the positioning rod is opened on the mounting seat, the inner wall of the receiving groove and the movable block are slidably matched, and one end of the spring away from the movable block is fixed to the bottom of the receiving groove.

[0010] The above technical solution is adopted to store the movable block and the spring in the normal state through the provision of the storage groove.

[0011] The utility model is further configured as follows: two sides of the bracket are provided with two slide grooves, and the interior of the two slide grooves is slidably connected with two sliders fixedly connected with the mounting seat.

[0012] The above technical solution is adopted to provide linear guidance for the movement of the mounting seat through the provision of the second slide groove and the second slider.

[0013] The utility model is further configured as follows: the internal thread of the mounting seat is connected with a locking bolt, and the bottom end of the locking bolt is in contact with the bracket.

[0014] By adopting the above technical solution, the locking bolt is set and tightened, so that the bottom end of the locking bolt contacts the bracket to generate friction, thereby positioning the mounting seat.

[0015] The utility model is further configured as follows: a fixing block 1 and a fixing block 2 are fixedly connected at the bottom of the bracket, and the adjusting screw is rotatably connected to the fixing block 1 and the fixing block 2 respectively through bearings.

[0016] By adopting the above technical solution, the fixed block 1 and the fixed block 2 cooperate with the bearing to limit the adjustment screw from rotating at a fixed position.

[0018] The utility model sets a support leg 1, a support leg 2, a ball, an adjusting screw, a slider 1 and a slide groove 1, and adjusts the two ball bearings to contact the two sides of the track respectively. At the same time, the surface of the ball bearings can be coated with lubricating oil. When the bracket is pushed to move on the track, the ball bearings can roll to remove the friction force, thereby reducing the friction resistance and improving the sensitivity of the bracket when moving. By setting a connecting seat, a connecting groove, a measuring host, a positioning groove and a positioning rod, the position of the measuring host can be limited, and when the measuring host is removed and then installed during the measurement process, it can be ensured that the measuring host is still in the original position, and there is no need to adjust the position of the measuring host again.

By setting the support leg 1 2, the support leg 2 3, the ball 4, the adjusting screw 5, the slider 1 6 and the slide groove 1 7, the two balls 4 can be adjusted to contact the two sides of the track respectively, and the surface of the ball 4 can be coated with lubricating oil. When the bracket 1 is pushed to move on the track, the ball 4 can roll to remove the friction force, thereby reducing the friction resistance and improving the sensitivity of the bracket 1 when moving. By setting the connecting seat 10, the connecting groove 9, the measuring host 11, the positioning groove 12 and the positioning rod 13, the position of the measuring host 11 can be limited, and when the measuring host 11 is removed and then installed during the measurement process, it can be ensured that the measuring host 11 is still in the original position, and there is no need to adjust the position of the measuring host 11 again.

[0025] Furthermore, a spring 14 is sleeved on the surface of the positioning rod 13, one end of the spring 14 is fixedly connected to the mounting seat 8 through a spring fixing piece, and the other end of the spring 14 is fixedly connected to a movable block 15 through a spring fixing piece, and the movable block 15 is fixedly sleeved on the positioning rod 13. Through the arrangement of the spring 14, when the positioning rod 13 and the movable block 15 move, the spring 14 will be pulled to extend and generate a rebound force; when the positioning rod 13 loses its pulling force, the rebound force of the spring 14 can pull the movable block 15 and the positioning rod 13 to reset; it should be noted that the rebound force of the spring 14 is greater than the weight of the positioning rod 13 and the movable block 15.

[0026] Furthermore, the mounting seat 8 is provided with a receiving groove 16 coaxial with the positioning rod 13, the inner wall of the receiving groove 16 is slidably matched with the movable block 15, and the end of the spring 14 away from the movable block 15 is fixed to the bottom of the receiving groove 16.

The fixed block 20 and the fixed block 21 cooperate with the bearings to limit the adjusting screw 5 from rotating at a fixed position.

[0030] Brief description of the use process: When in use, place the leg 2 on the outside of the track, and make the leg 2 and the ball 4 connected thereto in rotation contact with the track; by rotating the adjusting screw 5 clockwise, under the guidance of the slider 6 and the slide groove 7, the adjusting screw 5 drives the leg 2 3 to drive the ball 4 to move to another track until the ball 4 contacts the track.

[0031] Pull the positioning rod 13, so that the positioning rod 13 drives the movable block 15 to move, and the movable block 15 pulls the spring 14 to extend to generate a rebound force, and then the connecting seat 10 at the bottom of the measuring host 11 is inserted, and then the positioning rod 13 is released. Under the rebound force of the spring 14, the positioning rod 13 is reset and contacts the surface of the connecting seat 10;

[0032] By rotating the measuring host 11, the positioning groove 12 inside the connecting seat 10 is made to correspond to the positioning rod 13, and the positioning rod 13 will be engaged with the positioning groove 12 under the action of the rebound force of the spring 14, thereby limiting the connecting seat 10 and the measuring host 11 on its top; and if the measuring host 11 needs to be disassembled during the measurement process, the positioning rod 13 is pulled to separate the connecting seat 10, and the connecting seat 10 is pulled out; at this time, the position of the positioning rod 13 remains unchanged, and when the measuring host 11 is installed and fixed again, the positioning groove 12 opened in the connecting seat 10 at the bottom of the measuring host 11 will be engaged with the positioning rod 13 again, and the position of the positioning rod 13 has not changed from beginning to end, so it can be ensured that the measuring host 11 is still in the original position after being disassembled and then installed, so there is no need to adjust the position of the measuring host 11.

[0033] After the measuring host 11 is installed, by pushing the bracket 1 to move, the leg 1 2 at the bottom of the bracket 1 and the ball 4 inside the leg 2 3 and the track will rotate to remove the friction force, so that the bracket 1 can be pushed more flexibly without increasing the friction intensity, excessive force or insufficient force.

[0034] It should be noted that the lower the surface of the ball 4 is, the lower the friction coefficient of the ball 4 will be, and the more flexible the movement of the bracket 1 will be.
