Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a setting-out stake for asphalt road construction. Background Technology

[0002] In asphalt pavement construction, setting out lines is a crucial step to ensure that the pavement structure dimensions, slope, and flatness meet the design requirements, and setting out stakes are the core tool for achieving accurate setting out.

[0003] Asphalt pavement construction stakes typically consist of a high-strength main stake, adjustable positioning components, a wear-resistant marking layer, reflective warning devices, and a quick-fixing structure. Their working principle is as follows: the quick-fixing structure securely embeds the stake into the roadbed; the positioning components are adjusted to ensure the stake's elevation and verticality meet design parameters; and the wear-resistant marking layer and reflective devices provide clear reference information, guiding equipment such as pavers and rollers. In terms of operation, construction personnel measure the points on the pavement base according to the design drawings, use specialized tools to fix the stakes in place, calibrate the height and verticality using fine-tuning bolts, verify the marking information, and then double-check. Once confirmed to be correct, the stakes can be used as paving references. The stability of the stakes is checked regularly during construction.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional stakes are of fixed height and cannot be adapted to paving layers of different thicknesses in asphalt pavement construction. It is necessary to frequently replace stakes of different specifications, which affects construction efficiency. In view of this, we propose a stake for asphalt pavement construction. Utility Model Content

[0005] The purpose of this utility model is to provide a stake for asphalt pavement construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A type of stake for asphalt pavement construction includes a base, on which a pin is fitted, and on which an installation box is fixedly mounted. A lifting assembly is provided on the installation box, and the lifting assembly includes:

[0008] An elliptical cylinder is fixedly mounted on the mounting box. A motor is fixedly mounted inside the mounting box. A threaded rod is fixedly mounted on the output end of the motor. An elliptical cylinder is threaded onto the threaded rod. A limiting block is fixedly mounted on the elliptical cylinder.

[0009] Mounting bracket, the top of the elliptical cylinder is fixedly mounted on the mounting bracket, the mounting bracket is fixedly mounted on the mounting bracket, the vertical cylinder has a limiting groove inside, the vertical cylinder is fixedly mounted on the threaded bracket, and the threaded bracket is threadedly mounted on the threaded bracket;

[0010] A circular block is rotatably mounted on the mounting bracket. A rubber ring is fixedly mounted on the circular block. A circular plate is fixedly mounted on the circular block. A square block is fixedly mounted on the circular plate. A wire groove is formed on the square block.

[0011] In a further embodiment, multiple sets of the pins, limiting blocks, limiting grooves, threaded brackets, and fasteners are provided.

[0012] In a further embodiment, the elliptical cylinder slides inside the elliptical tube, the vertical tube is sleeved outside the elliptical tube, and the fastener is attached to the rubber ring.

[0013] In a further embodiment, multiple sets of the limiting blocks slide inside the limiting groove, and the front and rear ends of the wire groove are funnel-shaped.

[0014] In a further embodiment, the block is provided with an auxiliary component, which includes a spherical groove. The block has a spherical groove and an installation groove. An auxiliary ball is rotatably installed inside the block. One end of a spring is fixedly installed inside the block, and a hinge frame is fixedly installed at the other end of the spring. A support ball is hingedly installed on the hinge frame.

[0015] In a further embodiment, the auxiliary ball is disposed inside the spherical groove, the spring is disposed inside the mounting groove, and the hinge frame and support ball slide inside the mounting groove.

[0016] In a further embodiment, the mounting groove, spring, hinge bracket, and support ball are positioned directly below the spherical groove and the auxiliary ball, with the auxiliary ball and support ball located inside the wire groove.

[0017] Compared with the prior art, this utility model provides a setting-out stake for asphalt pavement construction, which has the following beneficial effects:

[0018] 1. This asphalt pavement construction line stake is equipped with a lifting component to adapt to the complex terrain of asphalt pavement construction. This component works with a motor to drive a threaded rod to rotate, causing the elliptical cylinder to slide along the elliptical tube, which in turn drives the mounting frame and circular plate to rise and fall synchronously. This adapts to the line setting height of different construction scenarios. The limiting block slides in the limiting groove to prevent the elliptical cylinder from rotating and ensure the stability of the guide trough direction. Tightening the fastener to fit the rubber ring can fix the angle of the circular block and meet the line setting requirements in different directions. The funnel design at the front and rear ends of the guide trough facilitates the introduction and export of wires and avoids wire jamming.

[0019] 2. This asphalt pavement construction stake is equipped with an auxiliary component to improve the quality and efficiency of asphalt pavement construction layout. This component works with an auxiliary ball that rolls in a spherical groove. When the wire passes through, it contacts the auxiliary ball, converting sliding friction into rolling friction and preventing wear on the wire surface. The support ball, under the action of a spring, pushes the wire upward to tighten it. It is suitable for wires of different diameters and prevents the layout deviation caused by wire slack. The hinge frame rotates adaptively with the wire diameter to ensure that the support ball always keeps in contact with the wire surface. Attached Figure Description

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.

[0033] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0034] Please see Figures 1-8 This utility model provides a technical solution:

[0035] A type of stake for asphalt pavement construction includes a base 1, on which a pin 2 is fitted, and on which an installation box 3 is fixedly installed. The base 1 provides stable support for the entire stake. During operation, the pin 2 is inserted into the ground through the base 1 to enhance the fixing effect of the base 1 and prevent the stake from tipping over during construction. The installation box 3 is used to install various functional components.

[0036] In one embodiment of this utility model, a lifting assembly 4 is provided on the mounting box 3. The lifting assembly 4 includes an elliptical cylinder 41. The elliptical cylinder 41 is fixedly mounted on the mounting box 3. A motor 42 is fixedly mounted inside the mounting box 3. A threaded rod 43 is fixedly mounted on the output end of the motor 42. An elliptical cylinder 44 is threadedly mounted on the threaded rod 43. A limiting block 45 is fixedly mounted on the elliptical cylinder 41. A mounting frame 46 is fixedly mounted on the top of the elliptical cylinder 44. A vertical cylinder 47 is fixedly mounted on the mounting frame 46. A limiting groove 48 is opened inside the vertical cylinder 47. A threaded frame 49 is fixedly mounted on the vertical cylinder 47. Fasteners are threadedly mounted on the threaded frame 49. 410. A circular block 411 is rotatably mounted on the mounting bracket 46. A rubber ring 412 is fixedly mounted on the circular block 411. A circular plate 413 is fixedly mounted on the circular block 411. A square block 414 is fixedly mounted on the circular plate 413. A wire groove 415 is opened on the square block 414. Multiple sets of pins 2, limiting blocks 45, limiting grooves 48, threaded brackets 49 and fasteners 410 are provided. An elliptical cylinder 44 slides inside an elliptical cylinder 41. A vertical cylinder 47 is sleeved outside an elliptical cylinder 41. Fasteners 410 are attached to the rubber ring 412. Multiple sets of limiting blocks 45 slide inside limiting grooves 48. The front and rear ends of the wire groove 415 are funnel-shaped.

[0037] In this embodiment, according to the required layout height for asphalt pavement construction, the motor 42 inside the mounting box 3 is started. The output end of the motor 42 drives the threaded rod 43 to rotate. Since the elliptical cylinder 44 is threaded onto the threaded rod 43 and slides inside the elliptical cylinder 41, the rotation of the threaded rod 43 causes the elliptical cylinder 44 to slide up and down along the elliptical cylinder 41, thereby driving the mounting bracket 46 at the top of the elliptical cylinder 44 and related components to rise and fall synchronously, realizing the adjustment of the layout height to adapt to complex terrain. During the rising and falling process, multiple sets of limiting blocks 45 on the elliptical cylinder 41 slide within the limiting grooves 48 inside the vertical cylinder 47. To prevent the elliptical cylinder 44 from rotating and ensure the stability of the direction of the wire groove 415 on the square block 414, when it is necessary to adjust the wire laying direction, rotate the round block 411 on the mounting bracket 46. The round block 411 drives the round plate 413 and the square block 414 to rotate to the appropriate direction. Then tighten the fastener 410 on the threaded bracket 49 so that the fastener 410 fits against the rubber ring 412 on the round block 411. Use friction to fix the angle of the round block 411 to meet the wire laying requirements in different directions. The funnel-shaped design at both ends of the wire groove 415 facilitates the introduction and export of wires and avoids wire jamming.

[0038] In one embodiment of this utility model, an auxiliary component 5 is provided on the block 414. The auxiliary component 5 includes a spherical groove 51. The block 414 has a spherical groove 51 and a mounting groove 52. An auxiliary ball 53 is rotatably installed inside the block 414. One end of a spring 54 is fixedly installed inside the block 414. A hinge frame 55 is fixedly installed on the other end of the spring 54. A support ball 56 is hingedly installed on the hinge frame 55. The auxiliary ball 53 is located inside the spherical groove 51. The spring 54 is located inside the mounting groove 52. The hinge frame 55 and the support ball 56 slide inside the mounting groove 52. The mounting groove 52, the spring 54, the hinge frame 55, and the support ball 56 are located directly below the spherical groove 51 and the auxiliary ball 53. The auxiliary ball 53 and the support ball 56 are located inside the wire groove 415.

[0039] In this embodiment, when the wire passes through the conductor groove 415 for laying, the auxiliary component 5 comes into play. The auxiliary ball 53 inside the block 414 rolls in the spherical groove 51. The wire contacts the auxiliary ball 53, converting the sliding friction of the wire into rolling friction, reducing wear on the wire's surface. At the same time, the spring 54 in the mounting groove 52 pushes the hinge frame 55 and the support ball 56 upward, so that the support ball 56 presses against the wire. Because the spring 54 is elastic, it can adapt to wires of different diameters, preventing the wire from becoming loose during the laying process and avoiding laying deviation caused by wire looseness. The hinge frame 55 can rotate adaptively with the wire diameter, ensuring that the support ball 56 always fits against the wire surface, further improving the quality and efficiency of asphalt pavement construction laying.

[0040] After the line laying operation is completed, turn off the motor 42. If it is necessary to move the line laying stake, pull out the pin 2, carry it to the next work point, and then put the pin 2 into the base 1 and insert it into the ground to fix it.

[0041] All electrical components mentioned in this application are electrically connected to the PLC controller and 220V AC mains power. The PLC controller is a conventional and known device capable of controlling the motor 42. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding, which are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. The supporting structures of the hydraulic drive structure mentioned in this application, such as hydraulic tanks and hydraulic pumps, are existing equipment and will not be described in detail here.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
