Description

Technical Field

[0001] This utility model relates to the field of asphalt paving technology, and in particular to an easily adjustable asphalt paving baseline stake. Background Technology

[0002] In the process of asphalt paving, in order to control the thickness and elevation of the asphalt paving, the wire rope baseline method is usually used in the paving of the base layer and the lower layer. That is, the wire rope baseline is set on both sides of the paving area to guide the paver sensor, thereby ensuring the paving accuracy.

[0003] Currently, the devices used to fix and support the wire rope baseline on both sides of the paving area are mostly simple steel stakes. During construction, operators will hammer the steel stakes directly into the ground and then tie the baseline to the steel stakes.

[0004] However, once the steel stake is inserted into the ground, it lacks effective support or a stable structure, making it highly susceptible to external disturbances. Especially in soft soil, it is prone to tilting or collapsing when touched by people, vibrated by equipment, or affected by wind. This instability causes shifts in the height and position of the baseline, transmitting incorrect elevation information to the paver and ultimately affecting the smoothness and thickness of the paved layer. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides an easily adjustable asphalt paving baseline stake. The technical solution of this utility model is as follows: An easily adjustable asphalt paving reference line stake includes a stake pole and a hanging plate. The lower end of the stake pole is pointed. A movable sleeve that can be adjusted along its height is fitted onto the lower outer side of the stake pole. At least three sets of fixed seats are fixedly fixed at equal intervals around the outer side of the movable sleeve. A support arm is hinged to the side of each set of fixed seats away from the movable sleeve. An adjustment component for adjusting the tilt angle of the corresponding support arm is connected inside each set of fixed seats. An adjustment sleeve that can be adjusted along its height is fitted onto the upper outer side of the stake pole. A folding mounting component is detachably connected to the outer wall of the adjustment sleeve. The hanging plate is laterally slidably disposed within the folding mounting component and fixed by a locking component.

[0006] Optionally, the movable sleeve is threaded onto the outside of the line pile upright.

[0007] Optionally, the lower end of the support arm is connected to a foot plate via a universal joint, the lower surface of the foot plate is glued with a foot pad, and a fixing lug for installing ground stakes is fixedly connected to one side of the foot plate.

[0008] Optionally, the fixed base has an internal cavity with an open top. The fixed base has a movable groove communicating with the cavity on the side near the support arm. The adjustment assembly includes a diagonal brace and an adjustment block. One end of the diagonal brace is hinged to the middle of the support arm, and the other end of the diagonal brace is hinged to a movable lug. The movable lug is slidably connected inside the movable groove. An adjustment block is fixedly connected to the side of the movable lug away from the diagonal brace. The adjustment block is vertically slidable in the cavity, and an adjustment rod for adjusting its height is connected to the adjustment block.

[0009] Optionally, the upper opening of the fixed base is detachably connected to an end cap, and a threaded hole is provided through the center of the end cap. The adjusting rod is threadedly connected inside the threaded hole, and the lower end of the adjusting rod is rotatably connected to the upper surface of the adjusting block.

[0010] Optionally, the adjusting sleeve is vertically slidable on the outside of the line stake upright, and two sets of locking nuts are threaded on the outside of the line stake upright, with the two sets of locking nuts respectively abutting against the upper and lower end faces of the adjusting sleeve.

[0011] Optionally, the folding mounting component includes a cross plate and a U-shaped rail. The cross plate is fixedly connected to the outer wall of the adjusting sleeve by bolts. The U-shaped rail is rotatably connected to the front center position of the cross plate by a rotating shaft. An ear plate is fixedly connected to the lower end of the U-shaped rail. A fixing bolt for relative fixation with the cross plate is threaded on the ear plate. Limiting hole one and limiting hole two are opened at corresponding positions on the front side of the cross plate. When the end of the fixing bolt abuts against the limiting hole, the U-shaped insert rail and the hanging plate on its inner side remain relatively perpendicular to the pole. When the end of the fixing bolt abuts against the second limiting hole, the U-shaped insert rail and the hanging plate on its inner side remain relatively parallel to the pole.

[0012] Optionally, a through hole is provided at the center of the front side of the U-shaped rail, the hanging plate is slidably connected to the inside of the U-shaped rail, a square groove is provided on the front side of the hanging plate, and the locking member is a locking bolt, the end thread of the locking bolt passes through the through hole and abuts in the square groove.

[0015] The beneficial effects of this utility model through the above solution are as follows: 1. This utility model utilizes an auxiliary support structure consisting of a movable sleeve and multiple sets of support arms on the outside of the line stake upright. This allows the line stake upright to be supported from multiple directions after being inserted into the ground, effectively avoiding the problem of existing steel stakes easily tilting or falling due to lack of support, thus greatly enhancing its stability. Secondly, the tilt angle of each set of support arms can be independently adjusted via its corresponding adjustment components. This allows the auxiliary support structure to adapt to uneven ground. By adjusting the unfolding angle of each support arm, the auxiliary support structure can maintain stability even on uneven terrain. Furthermore, the relative height of the movable sleeve on the outside of the line stake upright can be flexibly adjusted according to the depth of the line stake upright inserted into the ground, thereby achieving convenient height adjustment of the auxiliary support structure.

[0016] 2. By incorporating foldable mounting hardware and a hanging plate, the hanging plate can not only be adjusted laterally to change its horizontal position and achieve precise control of the hanging position, but it can also be folded up when not in use, thus reducing its volume during transportation and storage. Furthermore, the relative height of the adjusting sleeve to the outside of the line stake pole can be flexibly adjusted according to the height of the baseline, thereby achieving overall height adjustment of the hanging plate.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] Please see Figure 1-8 This utility model provides an easily adjustable asphalt paving reference line stake, including a stake pole 1 and a hanging plate 9. The lower end of the stake pole 1 is set as a pointed tip. The lower outer end of the stake pole 1 is fitted with a movable sleeve 2 that can be adjusted along its height direction. At least three sets of fixed seats 3 are fixedly fixed at equal intervals around the outer side of the movable sleeve 2. Each set of fixed seats 3 is hinged to a support arm 4 on the side away from the movable sleeve 2. Each set of fixed seats 3 is connected to an adjustment component 6 for adjusting the tilt angle of the corresponding support arm 4. The upper outer end of the stake pole 1 is fitted with an adjustment sleeve 7 that can be adjusted along its height direction. The outer wall of the adjustment sleeve 7 is detachably connected to a folding mounting piece 8. The hanging plate 9 is laterally slidably disposed in the folding mounting piece 8 and fixed by a locking piece 94.

[0022] This invention utilizes an auxiliary support structure consisting of a movable sleeve 2 and multiple sets of support arms 4, installed on the outer side of the line stake erector 1. This allows the line stake erector 1 to be supported from multiple directions by the support arms 4 after being inserted into the ground, effectively avoiding the problem of existing steel stakes easily tilting or falling due to lack of support, thus greatly enhancing its stability. Secondly, the tilt angle of each set of support arms 4 can be independently adjusted by its corresponding adjustment component 6. This allows the auxiliary support structure to adapt to uneven ground. By adjusting the unfolding angle of each support arm 4, the auxiliary support structure can maintain stability even on uneven terrain. Furthermore, the relative height of the movable sleeve 2 on the outer side of the line stake erector 1 can be adjusted according to the depth of the line stake erector 1 inserted into the ground, thereby achieving overall height adjustment of the auxiliary support structure.

[0023] By incorporating a foldable mounting bracket 8 and a hanging plate 9, the hanging plate 9 can not only be adjusted laterally to change its horizontal position and achieve precise control of the hanging position, but it can also be folded up when not in use, thereby reducing its volume during transportation and storage. Furthermore, the relative height of the adjusting sleeve 7 to the outside of the line stake pole 1 can be adjusted according to the height of the baseline, thus achieving overall height adjustment of the hanging plate 9.

[0024] Specifically, three sets of support arms 4 are preferred, and these three sets of support arms 4 can provide the necessary stable support force for the line stake pole 1. In addition, the number of fixing bases 3 and support arms 4 can also be four or more, as long as they can provide stable support for the line stake pole 1.

[0025] Furthermore, the movable sleeve 2 is threaded onto the outside of the online pile pole 1.

[0026] Specifically, when adjusting the relative height of the movable sleeve 2 to the outside of the line stake pole 1, the height adjustment can be easily completed simply by rotating the movable sleeve 2.

[0027] Furthermore, the lower end of the support arm 4 is connected to a foot plate 5 via a universal joint 41. A foot pad 51 is adhered to the lower surface of the foot plate 5, and a fixing lug 52 for installing ground nails is fixedly connected to one side of the foot plate 5.

[0028] Specifically, due to the unevenness of the construction ground, when the support arm 4 is extended and pressed down, the universal joint 41 allows each foot plate 5 to rotate independently at a certain angle, ensuring that the lower surface of the foot plate 5 is in contact with the ground as much as possible, greatly enhancing the stability and load-bearing capacity of the line stake 1 on inclined and rugged terrain. Secondly, the foot plate 5 can increase the contact area between the support arm 4 and the ground, further enhancing its stability. The foot pads 51 are made of non-slip and wear-resistant materials such as rubber and engineering plastics. In addition, the fixing lugs 52 can be used to install ground stakes. When the ground is relatively soft and the insertion of the line stake 1 alone is not enough to secure it, the ground stakes can be passed through the fixing lugs 52 and inserted into the ground, thereby achieving secondary fixation and greatly improving the stability of the entire auxiliary support structure.

[0029] Furthermore, the fixed base 3 has a cavity 31 with an open top. The fixed base 3 has a movable groove 32 connected to the cavity 31 on the side near the support arm 4. The adjustment assembly 6 includes a diagonal brace 61 and an adjustment block 63. One end of the diagonal brace 61 is hinged to the middle of the support arm 4, and the other end of the diagonal brace 61 is hinged to a movable ear 62. The movable ear 62 is slidably connected inside the movable groove 32. The side of the movable ear 62 away from the diagonal brace 61 is fixedly connected to the adjustment block 63. The adjustment block 63 is vertically slidable in the cavity 31, and an adjustment rod 64 for adjusting its height is connected to the adjustment block 63.

[0030] Specifically, guide grooves 33 are provided on both sides of the cavity 31, and guide protrusions 631 that cooperate with and slide in the guide grooves 33 are fixedly connected to both sides of the adjusting block 63. The cooperation between the guide protrusions 631 and the guide grooves 33 allows the adjusting block 63 to move along a predetermined path when it slides in the cavity 31.

[0031] Specifically, the relative height of the adjusting block 63 in the cavity 31 is adjusted by adjusting rod 64. The adjusting block 63 drives the movable ear seat 62 to slide vertically. Under the action of the diagonal brace 61, the angle of the support arm 4 changes.

[0032] Furthermore, the upper opening of the fixed base 3 is detachably connected to an end cap 34, and a threaded hole 341 is provided through the center of the end cap 34. The adjusting rod 64 is threadedly connected inside the threaded hole 341, and the lower end of the adjusting rod 64 is rotatably connected to the upper surface of the adjusting block 63.

[0033] Specifically, the upper end of the adjusting rod 64 is detachably connected to a knob via bolts, facilitating the rotation of the adjusting rod 64. When it is necessary to adjust the tilt angle of the support arm 4, simply rotate the knob. The knob drives the adjusting rod 64 to rotate. With the threaded engagement between the adjusting rod 64 and the threaded hole 341, the adjusting rod 64 will undergo vertical displacement with the end cover 34 during rotation, thereby causing the adjusting block 63 to slide vertically.

[0034] Furthermore, the adjusting sleeve 7 is vertically slidable on the outside of the line stake pole 1, and two sets of locking nuts 71 are threaded on the outside of the line stake pole 1, with the two sets of locking nuts 71 respectively abutting against the upper and lower end faces of the adjusting sleeve 7.

[0035] Specifically, the two sets of locking nuts 71 are used to limit the upper and lower positions of the adjusting sleeve 7. When it is necessary to adjust the adjusting sleeve 7 to move downward outside the pole 1, first rotate the lower locking nut 71 to lower it, then move the adjusting sleeve 7 downward so that it abuts against the upper end of the lower locking nut 71, and finally rotate the upper locking nut 71 to lower it and abut against the upper end face of the adjusting sleeve 7.

[0036] Furthermore, the folding mounting component 8 includes a cross plate 81 and a U-shaped rail 83. The cross plate 81 is fixedly connected to the outer wall of the adjusting sleeve 7 by bolts. The U-shaped rail 83 is rotatably connected to the front center position of the cross plate 81 by a rotating shaft 82. The lower end of the U-shaped rail 83 is fixedly connected to an ear plate 832. The ear plate 832 is threaded with a fixing bolt 833 for relative fixation with the cross plate 81. Limiting holes 1 811 and 2 812 are opened at corresponding positions on the front side of the cross plate 81. When the end of the fixing bolt 833 abuts against the limiting hole 811, the U-shaped rail 83 and the hanging plate 9 on its inner side remain relatively perpendicular to the pole 1. When the end of the fixing bolt 833 abuts against the limiting hole 812, the U-shaped insert rail 83 and the hanging plate 9 on its inner side remain relatively parallel to the pole 1.

[0037] Specifically, the first limiting hole 811 is located at the six o'clock position of the cross plate 81, and the second limiting hole 812 is located at the three o'clock position of the cross plate 81. Thus, when the U-shaped insert rail 83 and the hanging plate 9 need to be unfolded for use, simply unscrew the end of the fixing bolt 833 from the second limiting hole 812, then rotate the U-shaped insert rail 83 clockwise by ninety degrees. At this time, the U-shaped insert rail 83 and the hanging plate 9 remain relatively perpendicular to the line post 1. Finally, screw the end of the fixing bolt 833 into the first limiting hole 811.

[0038] Furthermore, a through hole 834 is provided at the center of the front side of the U-shaped rail 83, and the hanging plate 9 is laterally slidably connected inside the U-shaped rail 83. A positioning protrusion 831 is fixedly connected to the inner side wall of the U-shaped rail 83. A positioning groove 92 that slides and cooperates with the positioning protrusion 831 is provided on the rear side wall of the hanging plate 9. A square groove 93 is provided on the front side of the hanging plate 9. The locking member 94 is a locking bolt. The threaded end of the locking bolt passes through the through hole 834 and abuts against the square groove 93.

[0039] Specifically, when it is necessary to adjust the horizontal position of the hanging plate 9 by sliding it horizontally, simply loosen the locking bolt, then adjust the hanging plate 9 horizontally according to the actual needs, and tighten the locking bolt after the adjustment is completed, thereby achieving precise control of the hanging position.

[0040] Furthermore, a hanging groove 91 is provided at the upper edge of the hanging plate 9 and at the end away from the pole 1.

[0041] Specifically, the wire hanging groove 91 is used to place the baseline. The side wall of the wire hanging plate 9 and below the wire hanging groove 91 has two or more sets of round holes, which can be used to tie and fix the baseline by passing iron wire through the round holes when necessary.

[0042] Working principle: First, the line stake 1 is inserted into the ground using its pointed end, and then leveled using a bubble level to ensure it is perpendicular to the horizontal plane. Next, the relative height of the movable sleeve 2 to the outside of the line stake 1 is adjusted according to its insertion depth to ensure the auxiliary support structure is in contact with the ground. Then, the tilt angle of each set of support arms 4 is adjusted according to the actual flatness of the ground, thereby indirectly changing the height of the foot plate 5 until it contacts the ground. Next, the U-shaped rail 83 and the hanging plate 9 are rotated 90 degrees clockwise to unfold, and the relative position of the hanging plate 9 within the U-shaped rail 83 is adjusted laterally according to the horizontal position of the baseline. Finally, the baseline is installed in the hanging groove 91.

[0043] Furthermore, this device is highly adaptable and can be used on hardened surfaces and other areas where insertion is difficult. During use, there is no need to insert the stake 1 into the ground; simply adjust the movable sleeve 2 to the lowest position of the stake 1, and then adjust the tilt angle of each set of support arms 4 to ensure that the stake 1 remains perpendicular to the horizontal plane. At this point, the stake 1 is stably positioned under the support of multiple sets of support arms 4. In cases of poor stability, load-bearing blocks can be placed on each set of foot plates 5 to enhance stability.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
