Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide wire control pile technology, specifically a guide wire control pile for a municipal road paver. Background Technology
[0002] The construction of municipal road base courses and asphalt surface courses mainly utilizes pavers, employing a "line-following method" that uses an absolute benchmark to control the paving elevation. While the paver automatically levels itself, an accurate longitudinal slope benchmark is crucial for both base and asphalt surface paving. In municipal road construction, paver guide control stakes are a critical component of the line-following method, decisively impacting both construction quality and speed. However, existing paver guide control stakes suffer from inflexible placement, cumbersome control processes, and time-consuming preparation. Therefore, we need to develop a novel paver guide control stake design to address these issues. Summary of the Invention
[0003] The purpose of this utility model is to provide a guide control stake for a municipal road paver to solve the existing problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A guide control stake for a municipal road paver includes a tripod base, an adjustment assembly on the top plate of the tripod base, a laser rangefinder on the adjustment assembly, and a laser collimator on the top of the laser rangefinder.
[0005] The adjustment assembly includes a threaded sleeve, which is fixedly mounted at the center of the top plate of the tripod base. A lead screw is threaded into the inner thread of the threaded sleeve, and a steel pipe is rotatably connected to the top of the lead screw. A straight top support is fixedly connected to the top of the steel pipe, and a bracket is fixedly connected to the side wall of the straight top support. The laser rangefinder and laser collimator are mounted on the bracket.
[0006] Furthermore, the straight top bracket is fixed to the bracket by screws, and one side of the straight top bracket is fixedly connected to one side of the bracket by screws.
[0007] Furthermore, the top of the straight support is fitted with an anti-slip pad.
[0008] Furthermore, there are two anti-slip pads on the straight top support, and the two anti-slip pads are symmetrically arranged with the vertical line of the straight top support as the axis of symmetry.
[0009] Furthermore, each leg of the tripod base is equipped with anti-slip studs on its bottom.
[0010] Furthermore, there are multiple anti-slip studs, which are evenly spaced at the bottom of the tripod legs.
[0011] The guide control stake for the municipal road paver described in this utility model uses anti-slip nails to firmly fix the tripod base to the contact surface, ensuring the overall stability of the device and reducing construction vibration interference. A laser rangefinder detects the height of the top support, enabling millimeter-level precise adjustment and significantly improving the accuracy of the guide baseline layout. When height adjustment is needed, one hand holds the top support to prevent rotation, while the other hand rotates the screw threaded into the threaded sleeve. The rotation of the screw raises or lowers the top support, making height adjustment more convenient and efficient, and shortening construction preparation time. The aluminum alloy guide baseline abuts against the groove on the top support, and with the cooperation of the anti-slip pad, it is more firmly abutted against the top support, effectively preventing slippage and ensuring the stability of the paving baseline. A laser collimator visually displays the deviation of the aluminum alloy guide baseline, facilitating quick correction and ensuring precise alignment between the aluminum alloy guide baseline and the paver, ultimately improving the smoothness and thickness uniformity of the asphalt pavement.
[0012] This utility model is scientifically designed, structurally sound, simple to operate, and easy to use. Compared with traditional methods, the efficiency of setting up control stakes is improved by more than 30%. Moreover, the control stakes of this utility model can meet the requirements of different paving thicknesses. The flatness error of the paved road section using the control stakes of this utility model can be less than 3 mm, which is significantly better than the standard requirements, providing a reliable guarantee for the high-quality construction of municipal roads.

[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] like Figures 1 to 4 As shown, this embodiment provides a guide control stake for a municipal road paver, including a tripod base 1. The tripod base 1 includes a top plate, and three legs are evenly distributed and fixed around the perimeter of the top plate. Each leg is provided with an anti-slip nail 2 at its bottom. There are multiple anti-slip nails 2 on each leg, and the multiple anti-slip nails 2 are evenly distributed at the bottom of the legs of the tripod base 1.
[0020] An adjustment assembly 3 is provided on the top plate of the tripod base 1. The adjustment assembly 3 includes a threaded sleeve 301, which is fixedly inserted into the center of the top plate of the tripod base 1. A lead screw 302 is threadedly connected to the internal thread of the threaded sleeve 301. A steel pipe 303 is rotatably connected to the top of the lead screw 302. The steel pipe 303 can rotate relative to the lead screw 302. A straight top support 304 is fixedly connected to the top of the steel pipe 303. A bracket 3 is fixedly connected to the side wall of the straight top support 304. 07. One side of the straight top support 304 is fixedly connected to one side of the bracket 307 by screws 306. The straight top support 304 and the bracket 307 form a fixed structure by screws 306. The top of the straight top support 304 is provided with a slot for clamping the aluminum alloy wire reference line. The top of the straight top support 304 is fitted with two anti-slip pads 305. The two anti-slip pads 305 are symmetrically arranged with the vertical line of the straight top support 304 as the axis of symmetry.
[0021] A laser rangefinder 4 is mounted on bracket 307, and a laser collimator 5 is mounted on top of the laser rangefinder 4.
[0022] The working principle of the guide control stake for the municipal road paver described in this embodiment is as follows: The guide control stakes of the municipal road paver described in this embodiment are arranged at certain intervals on both sides of the road. The tripod base 1 is placed on the ground and fixed to the ground by the anti-slip nails 2 on it. According to the calculated thickness of the road structure layer, the laser rangefinder 4 is turned on to display the height value of the straight top support 304 in real time. The screw 302 is rotated so that the screw 302 rotates in the threaded sleeve 301. The screw 302 drives the straight top support 304 to move up and down, and the height adjustment of the straight top support 304 is completed to meet the design requirements. The aluminum alloy guide baseline is abutted in the slot on the straight top support 304 of each control stake. The anti-slip pad 305 further increases the stability of the abutment. The two ends of the aluminum alloy guide baseline are tightened with a tensioner. The laser collimator 5 is turned on so that the deviation of the aluminum alloy guide baseline can be seen and adjusted. After the adjustment is completed, a precise baseline is finally formed. The paver can then pave according to the baseline of this section.
