Description

Technical Field

[0001] This utility model relates to the field of road and bridge engineering technology, specifically to a pile body limiting mechanism for a pile driver. Background Technology

[0002] Corrugated beam guardrails are continuous structures made of corrugated steel guardrail panels spliced ​​together and supported by posts. They are typically installed on both sides of highways and main roads. When a vehicle collides with the guardrail due to loss of control or other reasons, its structure can effectively absorb and disperse the energy generated during the collision, reducing accident damage. Corrugated beam guardrails are widely used on highways, rural roads, bridge roads, and municipal roads due to their advantages such as low maintenance costs, strong corrosion and weather resistance, good impact resistance, good visibility, and convenient and quick installation. They are one of the key facilities for ensuring road traffic safety.

[0003] During the installation of corrugated guardrails, a large number of piles need to be driven into the roadbed. While ensuring efficiency, the verticality of the piles to the ground also requires a high degree of precision. Currently, to ensure that the piles do not tilt during construction with existing pile drivers, manual straightening and calibration are necessary. This is not only time-consuming and labor-intensive, but also poses safety hazards as workers spend long periods of time in the pile driving area. Utility Model Content

[0018] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] See Figures 1-9 As shown, a pile limiting mechanism 12 for a pile driver includes a main support 1 and an opening / closing device 8. The main support 1 is mounted on the pile driver 10, and the opening / closing device 8 is movably connected to the main support 1. The opening / closing device 8 and the main support 1 enclose a limiting space for the pile 11 to pass through. The first end of the opening / closing device 8 is rotatably connected to the first end of the main support 1 via a first hinge, and the second end of the opening / closing device 8 is detachably connected to the second end of the main support 1 via a second hinge. This invention has a simple structure; during use, the pile 11 can be installed with the limiting mechanism simply by opening and closing the opening / closing device 8. The operation is simple, and the structure of the first guide roller 2 and the second guide roller 805 reduces the resistance during pile driving, improving pile driving efficiency. It is applicable to piles 11 with various cross-sections, making the device widely applicable.

[0020] Preferred, such as Figure 1 As shown, the main support 1 is U-shaped, and the opening and closing device 8 blocks the opening of the main support 1. The internal lengths of the three sides of the main support 1 are the same, thereby cooperating with the opening and closing device 8 to limit the position of the pile 11 with a circular or square cross-section.

[0021] Preferred, such as Figure 1 and Figure 3 As shown, a first guide roller 2 is rotatably mounted on the side of the main support 1, and the axial direction of the first guide roller 2 is perpendicular to the driving direction of the pile body 11. In this embodiment, there are three first guide rollers 2, located on the three sides of the main support 1, which can tighten the three sides of the pile body 11 while reducing the friction between the rollers and the pile body 11, thereby reducing the resistance generated during pile driving. The first guide roller 2 is provided with a roller shaft 6, and the roller surface of the first guide roller 2 can rotate relative to the roller wheel.

[0022] Preferably, the main support 1 includes a first base plate 101 and an adjustment assembly. The adjustment assembly includes two adjustment plates 3, which are fixedly spaced on the first base plate 101. A first guide roller 2 is located between the two adjustment plates 3. Each adjustment plate 3 has a slotted hole, and the first guide roller 2 is adjustablely mounted on the adjustment plate 3 via a mounting bolt 4 passing through the slotted hole and secured with a mounting nut. Specifically, the main support 1 also includes a first top plate 102 opposite to the first base plate 101. The top of the adjustment plate 3 is fixed to the first top plate 102, and the bottom of the adjustment plate 3 is fixed to the first base plate 101. Both the first top plate 102 and the first base plate 101 are U-shaped. The length direction of the slotted hole is the same as the width direction of the first top plate 102 and the first base plate 101. The first guide roller 2 is located between the first top plate 102 and the first base plate 101 and can move towards or away from the limiting space, thereby adapting to piles 11 with different cross-sections and radii.

[0023] Preferably, the adjusting assembly further includes a first fixing plate 401 fixed to both ends of the roller shaft 6 of the first guide roller 2, and the mounting bolts 4 are fixed to the first fixing plate 401. The first fixing plate 401 is located between the two adjusting plates 3 and is attached to the two adjusting plates 3 respectively. Since the first fixing plate 401 is fixed to the roller shaft 6, the first guide roller 2 can be moved back and forth through the first fixing plate 401. In this embodiment, there are three mounting bolts 4 at each end of the first guide roller 2, and the three mounting bolts 4 are spaced apart. There are also three waist holes, which are arranged one-to-one with the three mounting bolts 4.

[0024] Preferably, a second fixing plate 402 is vertically fixed to the side of the first fixing plate 401 opposite to the limiting space. An adjusting screw 5 is screwed through the second fixing plate 402, and the nut end of the adjusting screw 5 abuts against the adjusting plate 3. An adjusting nut is screwed onto the screw of the adjusting screw 5, and the adjusting nut is located on the side opposite to the adjusting plate 3. The adjusting plate 3 is parallel to and adjacent to the first fixing plate 401, so the second fixing plate 402 is also relatively perpendicular to the adjusting plate 3. The second fixing plate 402 has a threaded through hole, which corresponds to the adjusting plate 3, and the adjusting screw 5 is screwed through the threaded through hole. During adjustment, the six mounting bolts 4 on both sides of the adjusting plate 3 are loosened first, and then the adjusting nuts on both sides of the second fixing plate 402 are rotated to control the screw-in length of the adjusting screw 5, thereby controlling the first fixing plate 401 to move back and forth. The first fixing plate 401 drives the first guide roller 2 to move back and forth, thereby adjusting the distance between the first guide roller 2 and the pile body 11. Figures 4-6 This is a schematic diagram showing how the mechanism adapts to different pile types 11. Figure 4 A round pile with an outer diameter of φ140mm. Figure 5 It is a round pile with an outer diameter of φ114mm, and Figure 6This is a schematic diagram of a square pile with an outer side length of 130mm.

[0025] Preferred, such as Figure 2 As shown, the opening and closing device 8 includes a left mounting plate 801, a right mounting plate 802, and a second guide roller 805. The left mounting plate 801 is detachably connected to the second end of the main support 1 via a second hinge. The right mounting plate 802 is rotatably connected to the first end of the main support 1 via a first hinge. The second guide roller 805 is rotatably connected between the left mounting plate 801 and the right mounting plate 802. Furthermore, a second top plate 803 is provided above the second guide roller 805, and a second bottom plate 804 is provided below it. First fixing plates 401 are provided on both ends of the second guide roller 805. The two ends of the roller shaft 6 of the second guide roller 805 are fixed to the first fixing plates 401, and two mounting bolts 4 are fixed on the first fixing plates 401. The left mounting plate 801 and the right mounting plate 802 are provided with waist holes for the mounting bolts 4 to pass through, and are provided with the first fixing plate 401, the second fixing plate 402, and the adjusting screw 5. The structure is the same as that of the first guide roller 2. The screwing length of the adjusting screw 5 is limited by the adjusting nut, thereby controlling the first fixing plate 401 to move back and forth. The first fixing plate 401 drives the second guide roller 805 to move back and forth, thereby realizing the adjustment of the distance between the second guide roller 805 and the pile body 11.

[0026] Preferred, such as Figures 4-9 As shown, the main support 1 is provided with a third fixing plate 13 for installation on the pile driver 10. The third fixing plate 13 is detachably connected to the bottom of the pile driver 10 by bolts, so that the pile driving position can be changed with the pile driver 10, and the bottom of the pile body 11 does not shake during pile driving.

[0027] Preferred, such as Figure 3 As shown, the first hinge component is a limiting screw 7. The first end of the main bracket 1 and the right mounting plate 802 are provided with a first opening for the limiting screw 7 to pass through. Limiting nuts are screwed into both ends of the limiting screw 7. Specifically, both the left mounting plate 801 and the right mounting plate 802 are U-shaped, and the right mounting plate 802 has a first opening on its flange.

[0028] Preferred, such as Figures 4-6 As shown, the second hinge component is a limiting pin 9. A second opening for the limiting pin 9 to pass through is provided on the second end of the main bracket 1 and on the left mounting plate 801. Specifically, a second opening is provided on the flange of the left mounting plate 801. One end of the limiting pin 9 is a pin cap, and the other end is fitted with an R-shaped pin to prevent it from coming loose due to vibration during piling. By pulling out the pin and then removing the limiting pin 9, the opening and closing device 8 can be quickly opened to allow the pile body 11 to be inserted.

[0029] When using it, first install the pile limiting mechanism 12 at the end of the pile driver 10, such as... Figure 7 As shown; Before pile driving, the three first guide rollers 2 and one second guide roller 805 on the limiting mechanism are adjusted to fit the surface of the pile body 11. Generally, the specifications of the pile bodies 11 are the same in the same road section, so there is no need for repeated adjustment.

[0030] Upon entering the piling position, the pile body 11 is erected on the piling position. The pin on the limiting mechanism is removed, so that the opening and closing device 8 is in the open state. Then, the piling machine 10 is moved to the piling position. The piling machine 10 enters the construction position along the opening of the limiting mechanism, such as... Figure 8 As shown.

[0031] Limit the pile body 11, adjust the position of the pile driver 10 and the pile body 11. A guide device is provided between the end of the pile hammer propulsion mechanism and the pile body 11. Align the center position of the pile body 11 with the top of the pile hammer propulsion mechanism, then close the opening and closing device 8 and insert the limiting pin 9. Figure 9 As shown.

[0032] Before pile driving, personnel are evacuated. The pile driver 10 begins driving the pile body 11 into the ground with the pile hammer. The first guide roller 2 and the second guide roller 805 radially limit the pile body 11 to prevent it from tilting or shaking. In addition, as the pile body 11 enters the ground, the first guide roller 2 and the second guide roller 805 rotate around the roller shaft 6, and there is rolling friction contact between them and the pile body 11 to minimize the resistance generated by the limiting.

[0033] After the piling work is completed, the staff removes the limit pin 9, opens the opening and closing device 8, and the piling machine 10 moves in the opposite direction of the opening, exits the work station, and enters the next work station for construction.

[0034] The pile limiting mechanism 12 of the pile driver 10 of this utility model is installed at the bottom of the pile driver 10. During pile driving, the pile body 11 passes through the limiting space and is driven into the soil, thereby limiting the deviation and swaying of the lower part of the pile body 11 during pile driving. This solves the technical problem in the prior art that the pile driver 10 cannot guarantee that the pile body 11 of the corrugated guardrail will not tilt. The utility model, through the setting of the first guide roller 2 and the second guide roller 805, can reduce the friction on the pile body 11 during pile driving and avoid damage to the pile body 11. Moreover, the utility model can adapt to pile bodies 11 of different sizes and types. It has a simple structure, is easy to maintain, has few pre-construction operation steps, and is easy to carry out construction and move with the pile driver 10.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
