Description

Technical Field

[0001] This utility model relates to the field of pile driver technology, specifically a guide structure for a pile driver used in engineering construction. Background Technology

[0002] A pile driver is a large-scale engineering machine widely used in construction, bridges, streets, river embankments, underground continuous walls, retaining walls, and seepage prevention. It can drive various types of piles into the soil to improve the bearing capacity of the foundation. Its basic structure consists of a pile hammer, a guide pile frame, a power unit, and auxiliary equipment. According to the power source, it is divided into hammer pile drivers, vibratory pile drivers, and hydraulic pile drivers. Among them, the hammer pile driver uses the gravity acceleration of the hammer head to convert potential energy into kinetic energy. The impact between the hammer and the pile generates a powerful impact force in an instant, causing the pile to overcome the soil resistance and sink into the rock and soil.

[0003] Chinese Patent Publication No. CN112962599B discloses a tracked photovoltaic piling machine. It utilizes an adjustment mechanism to adjust the height, forward / backward tilt angle, and left / right tilt angle of the pile hammer frame. The pile hammer then impacts the pile, generating an impact force that drives the pile into the soil or rock.

[0004] In actual engineering construction, guide sleeves are needed to be fitted onto the pile head to prevent the pile hammer from directly impacting the pile column and causing damage to the pile head. If piles of various diameters or cross-sections need to be constructed, multiple sets of symmetrically arranged bolts need to be completely disassembled, and guide sleeves of the corresponding size need to be replaced, repositioned, and tightened. Each replacement is time-consuming and affects construction efficiency. Moreover, the high-frequency vibration generated by the impact of the falling hammer will be transmitted to the bolt connection. Long-term vibration can easily lead to the attenuation of bolt preload and loosening of nuts. If not checked and tightened in time, the guide sleeve may be displaced, or even cause safety hazards. Therefore, a guide structure for piling machines in engineering construction is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a guide structure for a pile driver used in engineering construction. It has the advantage of facilitating quick replacement of the guide sleeve, solving the problem that if multiple diameters or cross-sections of piles need to be constructed, multiple sets of symmetrically arranged bolts must be completely disassembled, and the guide sleeves of the corresponding sizes must be replaced, repositioned, and tightened. Each replacement is time-consuming and affects construction efficiency. Moreover, the high-frequency vibration generated by the impact of the falling hammer will be transmitted to the bolt connection. Long-term vibration can easily lead to the attenuation of bolt preload and loosening of nuts. If not checked and tightened in time, it may cause the guide sleeve to shift, or even cause safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guide structure for a piling machine in engineering construction, comprising a guide frame and a guide sleeve, wherein a connecting bracket connected to the guide sleeve is provided on the guide frame, and an installation component for installing the connecting bracket is provided on the guide frame;

[0007] The mounting assembly includes a mounting frame, the mounting frame having a clamping component for clamping the connecting bracket inside, and a positioning component for fixing the clamping component inside.

[0008] The positioning component includes a positioning frame, which is adapted to the mounting frame. Two symmetrically distributed pin plates are slidably mounted on the positioning frame. A locking plate is slidably mounted on the positioning frame. The pin plates and the locking plate are respectively connected to the mounting frame. The inclined surfaces of the pin plates and the locking plate are coplanar. A double threaded rod for controlling the movement of the locking plate and the positioning frame is rotatably mounted on the positioning frame.

[0009] The clamping component includes two T-shaped plates for clamping the connecting bracket, and the T-shaped plates are slidably connected to the mounting frame. Each of the two T-shaped plates is hinged with an L-shaped plate, and the two L-shaped plates are hinged to each other.

[0010] Furthermore, the mounting frame has two symmetrically distributed positioning slots that are adapted to the pin plate. The mounting frame has a locking slot, and the connecting bracket has a connecting slot that is aligned with the locking slot. The connecting slot and the locking slot are adapted to the locking plate, respectively.

[0011] Furthermore, the mounting frame has two symmetrically distributed clamping grooves, which are adapted to one end of the T-shaped plate. The mounting frame also has a guide groove, and one end of the T-shaped plate extends into the guide groove, with the guide groove and the T-shaped plate slidably connected.

[0012] Furthermore, two cross-shaped connecting cylinders are fixedly installed on the double-threaded rod, and the two threads on the double-threaded rod are symmetrically distributed, with two pin plates threaded onto the two threads respectively.

[0013] Furthermore, a sliding frame is slidably mounted on the guide frame, the sliding frame is fixedly connected to the mounting frame, and the guide sleeve is fixedly connected to the connecting bracket.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The guide structure of the pile driver in this project uses an installation component to achieve double locking and fixation of the connecting bracket by using the inclined wedge of the pin plate and locking plate, as well as the clamping force formed by the hinge of the two L-shaped plates pressed down by the mounting frame. The entire assembly process only requires inserting the connecting bracket, embedding the positioning frame, and rotating the cross connecting cylinder to lock the connecting bracket. Disassembly only requires the reverse steps. This allows for quick replacement of the guide sleeve of the corresponding size when dealing with piles of various diameters, shortening the replacement time and ensuring construction efficiency. Moreover, the use of both inclined wedge and interlocking locking methods avoids the problem of bolt preload attenuation caused by long-term vibration when using bolt fixation.

[0023] 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.

[0024] Example 1: Please refer to Figure 1-6The guide structure of a piling machine for engineering construction in this embodiment includes a guide frame 1 and a guide sleeve 5. A connecting bracket 4 connected to the guide sleeve 5 is provided on the guide frame 1, and an installation component 3 for installing the connecting bracket 4 is provided on the guide frame 1.

[0025] Example 2: Please refer to Figure 1-6 Based on Embodiment 1, the mounting component 3 includes a mounting frame 31, with a clamping component 32 for clamping the connecting bracket 4 inside the mounting frame 31, and a positioning component 33 for fixing the clamping component 32 inside the mounting frame 31.

[0026] The positioning component 33 includes a positioning frame 331, which is adapted to the mounting frame 31. Two symmetrically distributed pin plates 332 are slidably mounted on the positioning frame 331. A locking plate 333 is slidably mounted on the positioning frame 331. The pin plates 332 and the locking plate 333 are respectively connected to the mounting frame 31. The inclined surfaces of the pin plates 332 and the locking plate 333 are coplanar. A double threaded rod 334 for controlling the movement of the locking plate 333 and the positioning frame 331 is rotatably mounted on the positioning frame 331.

[0027] The clamping component 32 includes two T-shaped plates 321 for clamping the connecting bracket 4, and the T-shaped plates 321 are slidably connected to the mounting frame 31. Each of the two T-shaped plates 321 is hinged with an L-shaped plate 322, and the two L-shaped plates 322 are hinged to each other.

[0028] Two cross-shaped connecting cylinders 335 are fixedly installed on the double threaded rod 334. The two threads on the double threaded rod 334 are symmetrically distributed, and the two pin plates 332 are respectively threaded onto the two threads. Due to the symmetrical thread design of the double threaded rod 334, when the double threaded rod 334 is rotated by the cross-shaped connecting cylinders 335, the two pin plates 332 move synchronously in opposite directions.

[0029] In addition, a sliding frame 2 is slidably installed on the guide frame 1. The sliding frame 2 is fixedly connected to the mounting frame 31, and the guide sleeve 5 is fixedly connected to the connecting bracket 4, so that the vibration generated by the hammer driving the pile can be transmitted to the interior of the mounting frame 31 through the connecting bracket 4.

[0030] Using the above technical solution, when the double threaded rod 334 is rotated, the two pin plates 332 move in opposite directions synchronously. The inclined surfaces of the two pin plates 332 push the locking plate 333 into the mounting frame 31 and the connecting bracket 4. That is, the locking plate 333 is inserted into the locking groove 313 and the connecting groove 41, and rigid locking is achieved by using the wedge effect of the inclined surfaces.

[0031] Example 3: Please refer to Figure 1-6Based on Embodiment 2, the mounting frame 31 has two symmetrically distributed positioning grooves 311, which are adapted to the pin plate 332. The mounting frame 31 has a locking groove 313, and the connecting bracket 4 has a connecting groove 41, which is aligned with the locking groove 313. The connecting groove 41 and the locking groove 313 are adapted to the locking plate 333, respectively. The mounting frame 31 has two symmetrically distributed pressing grooves 312, which are adapted to one end of the T-shaped plate 321. The mounting frame 31 has a guide groove 314, and one end of the T-shaped plate 321 extends into the guide groove 314. The guide groove 314 and the T-shaped plate 321 are slidably connected.

[0032] Using the above technical solution, the positioning frame 331 is embedded inside the mounting frame 31. During this process, the positioning frame 331 presses the hinge of the two L-shaped plates 322, causing the two L-shaped plates 322 to gradually open and drive the T-shaped plate 321 to slide until one end of the T-shaped plate 321 is inserted into the inside of the pressing groove 312. The two T-shaped plates 321 are used to press the connecting bracket 4. At this time, the two L-shaped plates 322 are in a flat angle state.

[0033] The working principle of the above embodiments is as follows:

[0034] During assembly of the guide structure for the pile driver in this project, the opposite sides of the two T-shaped plates 321 are in contact with each other and are located in the middle of the mounting frame 31. At this time, the included angle of the two L-shaped plates 322 is an acute angle. The connecting bracket 4 is inserted into the reserved space of the mounting frame 31 so that its connecting groove 41 is aligned with the locking groove 313 of the mounting frame 31.

[0035] The positioning frame 331 is embedded inside the mounting frame 31. During this process, the positioning frame 331 presses the hinge of the two L-shaped plates 322, causing the two L-shaped plates 322 to gradually open and drive the T-shaped plate 321 to slide until one end of the T-shaped plate 321 is inserted into the inside of the clamping groove 312. The two T-shaped plates 321 are used to clamp the connecting bracket 4. At this time, the two L-shaped plates 322 are in a flat angle state.

[0036] Due to the symmetrical thread design of the double threaded rod 334, when the double threaded rod 334 is rotated using the cross connecting cylinder 335, the two pin plates 332 move synchronously in opposite directions. The inclined surfaces of the two pin plates 332 push the locking plate 333 into the mounting frame 31 and the connecting bracket 4. That is, the locking plate 333 is inserted into the locking groove 313 and the connecting groove 41, and rigid locking is achieved by using the wedge effect of the inclined surfaces.
