Abstract
Description
Technical Field
[0001] This utility model belongs to the field of compaction thickness measurement technology, and in particular relates to an auxiliary tooling for compaction thickness monitoring. Background Technology
[0002] With the continuous expansion of high-speed railway construction in my country, the number of transition sections is increasing. Currently, the main problem in the construction of high-speed railway subgrade transition sections is that the paving thickness is mostly marked manually with plumb lines, making it difficult to control the thickness of the subgrade paving layer. This makes it difficult to effectively guarantee the quality of subsequent compaction construction in the transition section, resulting in significant challenges in overall construction quality control. Therefore, there is an urgent need for those skilled in the art to propose a device capable of accurately measuring the layer thickness during compaction. Utility Model Content
[0003] In view of this, the present invention provides an auxiliary tooling for monitoring compaction thickness to solve the above problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An auxiliary tooling for monitoring compaction thickness includes: a layer thickness detection device and an anti-collision guide device. The layer thickness detection device includes a height measuring laser sensor and a height measuring control reference. The height measuring laser sensor is installed on the top side wall of a road roller, and the height measuring control reference is installed on the top side wall of a structure. The height measuring laser sensor passes through the height measuring control reference to detect the layer thickness during the road compaction process. The anti-collision guide device is installed on the side wall of the road roller to prevent the height measuring laser sensor from colliding with the structure when passing through the height measuring control reference.
[0006] Furthermore, the anti-collision guiding device includes an anti-collision guide wheel and a guide wheel bracket. The guide wheel bracket is fixedly installed on the side wall of the road roller, and the anti-collision guide wheel is rotatably installed in the guide wheel bracket.
[0007] Furthermore, the anti-collision guide wheel extends 0-2 cm beyond the height measuring laser sensor in the width direction of the road roller.
[0008] Furthermore, multiple anti-collision guiding devices are provided, and all of the multiple anti-collision guiding devices are installed on the side wall of the road roller.
[0009] Furthermore, it also includes lateral alarm radars, multiple of which are fixedly installed on the front and rear end side walls of the road roller.
[0010] The beneficial effects of this utility model are as follows:
[0011] In this invention, during the compaction process after road paving, the height-measuring laser sensor moves with the roller, passing over the height measurement control benchmark on the structure. By calculating the elevation difference between the roller's back and forth travels, it achieves accurate measurement of the layer thickness during road compaction. The anti-collision guide device prevents the height-measuring laser sensor from colliding with the structure when passing the height measurement control benchmark, thus avoiding damage to the laser sensor due to impact. The lateral alarm radar provides an automatic alarm function when the distance between the auxiliary wheel of the equipment and the structure is 0-5cm, alerting operators to safe operation and also preventing collisions between the height-measuring laser sensor and the structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] See attached document Figure 1-3As shown, this utility model provides an auxiliary tooling for compaction thickness monitoring, including: a layer thickness detection device 10 and an anti-collision guide device 20. The layer thickness detection device 10 includes a height measuring laser sensor 11 and a height measuring control reference 12. The height measuring laser sensor 11 is installed on the top side wall of the roller 40, and the height measuring control reference 12 is installed on the top side wall of the structure 50. The height measuring laser sensor 11 passes through the height measuring control reference 12 and is used to detect the layer thickness during the road compaction process. The anti-collision guide device 20 is installed on the side wall of the roller 40 and is used to prevent the height measuring laser sensor 11 from colliding with the structure 50 when it passes through the height measuring control reference 12.
[0020] During the compaction process after the road surface is paved, the height measurement laser sensor 11 moves with the road roller 40 and passes the height measurement control reference 12 on the structure 50. By calculating the elevation difference between the road roller 40 going back and forth, the layer thickness during the road compaction process is accurately measured.
[0021] In a preferred embodiment, the anti-collision guiding device 20 includes an anti-collision guide wheel 21 and a guide wheel bracket 22. The guide wheel bracket 22 is fixedly installed on the side wall of the road roller 40, and the anti-collision guide wheel 21 is rotatably installed in the guide wheel bracket 22. The anti-collision guide wheel 21 extends 0-2 cm beyond the height measuring laser sensor 11 in the width direction of the road roller 40. The anti-collision guide wheel 21 enables the road roller 40 to avoid physical collisions with the structure 50 during its movement. Even if the anti-collision guide wheel 21 contacts the structure 50, it can still provide guidance by rotating on its own, thus avoiding rigid collisions with the structure 50.
[0022] In a preferred embodiment, multiple anti-collision guide devices 20 are provided, and all multiple anti-collision guide devices 20 are installed on the side wall of the road roller 40, which further avoids rigid collision between the road roller 40 and the structure 50.
[0023] In a preferred embodiment, the auxiliary tooling for monitoring compaction thickness further includes lateral alarm radars 30, with multiple lateral alarm radars 30 fixedly installed on the front and rear end side walls of the roller 40. The lateral alarm radars 30 provide an automatic alarm prompt function when the distance between the auxiliary wheel of the equipment and the structure 50 is 0-5cm, thus preventing collisions between the height measuring laser sensor 11 and the structure 50.
