Embodiment 1

[0044] refer to figure 1 , this embodiment discloses an intelligent fine-tuning system for a ballastless track slab, including a measuring device 4 for measuring the position data of a ballastless track slab 3, four fine-tuning claws 2, and four for driving fine-tuning Adjustment mechanism 1 for jaws 2. The measurement device 4 adopts a total station, and a fine-tuning frame is placed on the corresponding rail platform, and the total station is erected to complete the installation of the total station. Four corners of the ballastless track slab 3 are respectively provided with a fine adjustment claw 2, and each fine adjustment claw 2 is respectively connected with an adjustment mechanism.

[0045] refer to figure 2 with image 3 , the adjustment mechanism includes a box body 101, and a box door 111 is also arranged on the box body 101. The box door 111 is arranged on the side of the box body 101 away from the fine adjustment claw 2, that is, the back side of the box body 1...

Embodiment 2

[0061] refer to Figure 7 with Figure 8 , the rest of this embodiment is the same as Embodiment 1, the difference is that in order to make the fine adjustment claw 2 itself have a certain position deviation compensation ability when adjusting, the bottom of the Z-direction screw rod 202 is set as a hemisphere Shaped connecting portion 225, on the X-direction slider 216, a receiving groove matching the hemispherical connecting portion 225 is provided, the connecting portion 225 is set in the receiving groove, and the connecting portion 225 is pressed into the In the storage slot, the connecting portion 225 cannot escape upwards from the storage slot. The pressing plate 224 is fixed to the X-direction sliding block 216 through locking screws 223 , and the connecting portion 225 is pressed into the receiving groove of the X-direction sliding block 216 . The Z-direction screw rod 202 can rotate on the X-direction slider 216 , and can also swing at a certain angle on the X-direc...

Embodiment 3

[0065] refer to Figure 10, the rest of this embodiment is the same as Embodiment 2, the difference is that in order to enable the adjustment mechanism 1 to be positioned and connected with the fine adjustment claw 2 more quickly, the box body 101 is arranged on a base 117, and the base 117 It is connected with the box body 101 through a lifting mechanism. In this embodiment, the lifting mechanism includes a fork 118 and an oil cylinder 104 . A lockable universal wheel 116 is arranged at the bottom of the base 117 , and a push handle 115 is also arranged on the base 117 .

[0066] When it is necessary to install the adjustment mechanism 1, push the adjustment mechanism 1 to the corresponding position, then adjust the oil cylinder 104, so that the box body 101 rises to a suitable height, and connect the four adjustment mechanisms 1 through the floating cross coupling 5 and fine adjustment The claw 2 is connected, and then inserted into the installation groove 61 on the positio...

Abstract

The invention discloses an intelligent fine adjustment system for a ballastless track plate. The system comprises a measurement device, a fine adjustment claw and an adjustment mechanism, and the measurement device sends ballastless track plate position data to a control host; the adjustment mechanism drives the fine adjustment claw to adjust the position of the ballastless track plate; the fine adjustment claw comprises a connecting plate and a screw rod sliding block mechanism; the screw rod sliding block mechanism comprises three adjusting heads, and the three adjusting heads rotate to be used for driving the connecting plate to conduct X-direction, Y-direction and Z-direction three-dimensional adjustment; and the adjustment mechanism comprises three driving motors and three speed reducers, each driving motor is connected with one speed reducer, and output shafts of the three speed reducers are connected with the three adjusting heads through dowel bars respectively. Adjustment parameters are obtained through a total station, a dowel bar connected with the fine adjustment claw is utilized, the motors drive the dowel bar to achieve fine adjustment of the track plate, the adjustedstate is fed back to the control host, automatic fine adjustment is conducted through equipment, and the track plate is adjusted to the required spatial position quickly and precisely.

Description

technical field [0001] The application relates to the technical field of railway construction, in particular to an intelligent fine-tuning system for ballastless track slabs. Background technique [0002] The track slab of high-speed railway is the foundation of rail laying. In order to meet the precision requirements of rail laying, the track slab needs to be precisely ground by machine tools in prefabrication production before being placed on the construction site. After the construction is completed, the positioning must be precisely adjusted to meet the requirements of the rail. laying requirements. [0003] At present, in the construction of ballastless track of railway bridges, the fine adjustment of track slabs can only be carried out at night. The efficiency of track fine adjustment at night affects the progress of the project. Improving the efficiency of fine adjustment of track slabs is crucial to ensure that the ballastless track project is completed on schedule ...
