Description

Technical Field

[0001] The utility model belongs to the technical field of pile driving, and in particular relates to a protective device for an anti-corrosion layer of a square pile. Background Art

[0002] In order to prevent the prefabricated square piles from rusting underground, an anti-corrosion layer needs to be applied to the outside of the prefabricated square piles. During the pile driving construction process, the pile holding machine needs to hold the square pile at one position and then press the pile body downward. After pressing it downward for a certain distance, the pile holding machine releases the original holding position and moves upward along the pile body to a suitable position and then holds the pile body again to press the pile body. This cycle is repeated until the prefabricated square pile is pressed to the set depth and the construction is stopped.

[0003] In the above construction process, because the pile holding machine directly holds the pile body and sends the pile downward, in order to ensure smooth pile delivery, the pile body must be clamped to prevent the pile body from slipping. However, the pile holding machine can easily damage the anti-corrosion layer coated on the outside of the prefabricated square pile during the pile delivery process, thereby reducing the anti-corrosion performance of the pile body.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0005] The utility model aims to provide a protective device for the anti-corrosion layer of a square pile, so as to solve the technical problem that the anti-corrosion layer of the prefabricated square pile is easily damaged during the existing pile pressing process.

[0006] In order to achieve the above-mentioned purpose, a protective device for the anti-corrosion layer of a square pile of the utility model provides the following technical solutions:

[0007] A protective device for a square pile anti-corrosion layer, comprising:

[0008] A rectangular parallelepiped frame having a channel for being sleeved on the outside of the square pile;

[0009] Clamping surfaces, two of which are arranged oppositely on the inner side wall of the channel;

[0010] A locking mechanism is arranged on the side wall of the rectangular parallelepiped frame and is used to drive the two clamping surfaces to clamp the square piles.

[0011] As a further optimized technical solution, two clamping plates are arranged opposite to each other in the rectangular parallelepiped frame, and the opposite side surfaces of the clamping plates constitute the clamping surfaces.

[0012] As a further optimized technical solution, the length of the splint is greater than the length of the channel, and the width of the splint is greater than the width of the square pile; arc chamfers are respectively provided at both ends of the splint to prevent the two ends of the splint from colliding with the square pile when being sleeved onto the outside of the square pile.

[0013] As a further optimized technical solution, the locking mechanism includes:

[0014] A locking block, wherein the locking block is hinged on the side wall of the rectangular parallelepiped frame, and a portion of the locking block extends into the channel to abut against the clamping plate, and the locking block is rotated away from the rectangular parallelepiped frame to push the clamping plate to clamp the square pile;

[0015] A driving rod is arranged on the top of the locking block and is fixedly connected to the locking block, and is used to push the locking block to rotate through the driving rod.

[0016] As a further optimized technical solution, the cross section of the locking block is in a cam shape.

[0017] As a further optimized technical solution, the clamping plate is connected to the inner wall of the channel by using an elastic member, so as to automatically reset toward the inner wall of the channel when there is no need to clamp the square piles, so as to loosen the square piles.

[0018] As a further optimized technical solution, soft and elastic protective layers are respectively fixedly connected to the opposite side walls of the two clamping plates.

[0019] As a further optimized technical solution, anti-slip grooves are provided on the side walls of the protective layer.

[0020] As a further optimized technical solution, a guide structure is provided on the side of the rectangular frame at one end of the driving rod away from the locking block, which is used to push the driving rod to rotate with the help of the guide structure when the pile gripper presses the pile downward.

[0021] As a further optimized technical solution, the guide structure (3021) is an arc-shaped guide surface.

[0022] Beneficial effect: By using this device, during the construction process, the rectangular frame is sleeved on the position where the pile holding machine holds the square pile. At this time, the clamping surface is locked by the locking mechanism to clamp the square pile. Since the pile holding machine no longer directly contacts the square pile, it is replaced by a clamping surface with a larger contact area with the square pile. Therefore, the anti-corrosion layer is no longer easily damaged during the pile delivery process, which solves the technical problem that the anti-corrosion layer of the prefabricated square pile is easily damaged during the existing pile driving process.

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the present invention.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0031] The utility model provides a protective device for the anti-corrosion layer of a square pile, which can be locked at the position where a pile gripper grips the square pile during construction, to prevent the pile gripper from directly contacting the square pile, thereby preventing the pile gripper from damaging the anti-corrosion layer on the square pile during construction.

[0032] Specific as Figure 1 , Figure 2 , Figure 3 As shown, the protective device of the square pile anti-corrosion layer includes a rectangular frame 1, a clamping surface, and a locking mechanism 3.

[0033] The rectangular parallelepiped frame 1 is formed by four side panels connected end to end, and the four side panels are formed in the process of being enclosed to form a channel 2 for being sleeved on the outside of the square piles 4.

[0034] Two clamping plates 5 are arranged opposite to each other in the rectangular parallelepiped frame 1 , and opposite side surfaces of the clamping plates 5 constitute clamping surfaces for clamping the square piles. Therefore, the two clamping surfaces are arranged opposite to each other on the inner side wall of the channel 2 .

[0035] The locking mechanism 3 is arranged on the side wall of the rectangular parallelepiped frame 1 and is used to drive the two clamping surfaces to clamp the square pile 4 .

[0036] In order to fully expand the contact area between the clamping surface and the square pile 4 and facilitate observation of the clamping of the square pile, the length of the clamping plate 5 is greater than the length of the channel 2, and both ends of the clamping plate 5 extend out of the rectangular frame 1 respectively; the width of the clamping plate 5 is greater than the width of the square pile 4.

[0037] In order to prevent the two ends of the clamping plate 5 from hitting the square pile 4 during the process of being put on the outside of the square pile 4, the two ends of the clamping plate 5 are respectively provided with arc chamfers 6. In this way, when the rectangular parallelepiped frame 1 is put on the square pile 4, the opposite arc chamfers 6 on the two clamping plates 5 form a trumpet-shaped opening, so that the square pile 4 is conveniently put on and it is not easy to hit the square pile 4.

[0038] In this embodiment, the locking mechanism 3 includes a locking block 301 and a driving rod 302 .

[0039] The locking block 301 is hinged on the outer wall of the rectangular frame 1, and there is a through hole starting from the hinge position. Part of the locking block 301 extends into the interior of the channel 2 through the through hole to abut the clamping plate 5. The cross-section of the locking block 301 is a cam shape. In this way, when the locking block 301 is rotated away from the rectangular frame 1, the part of the locking block 301 that penetrates into the channel 2 increases, thereby pushing the clamping plate 5 to clamp the square pile 4.

[0040] The driving rod 302 is disposed on the top of the locking block 301 and is fixedly connected to the locking block 301 , and is used to push the locking block 301 to rotate through the driving rod 302 .

[0041] Specifically, during the construction process, the pile holding machine holds the rectangular parallelepiped frame 1 tightly and presses the driving rod 302 when sending the pile downward, so that the locking block 301 presses the clamping plate 5. That is, the greater the pile sending force required by the pile holding machine to send the pile downward, the tighter the clamping plate 5 clamps the square pile 4. When the pile sending is completed, the pile holding machine stops applying force downward, and the locking block 301 is released, so that it is convenient to change the clamping position with the pile holding machine.

[0042] In order to facilitate the automatic reset of the clamping plate 5 toward the inner wall of the channel 2 to release the square piles when the square piles 4 are not needed, the clamping plate 5 is connected to the inner wall of the channel 2 by using a coil spring as an elastic member 7 .

[0043] In this way, when the driving rod 302 is compressed, the driving locking block 301 pushes the clamping plate 5 to move to a position close to the square pile 4 to clamp the square pile 4. At this time, the coil spring is in a stretched state. When the pile clamping machine needs to change the clamping position, after loosening the rectangular frame 1 and rotating the driving 302 in the reverse direction, the coil spring automatically contracts and pulls the clamping plate 5 to loosen the square pile 4.

[0044] In order to further protect the anti-corrosion layer, a soft elastic protective layer 8 is fixedly connected to the opposite side walls of the two clamping plates 5. In this embodiment, the protective layer 8 is made of rubber material.

[0045] In order to further prevent the clamping plate 5 from sliding relative to the square pile 4 when supporting the square pile 4, anti-slip grooves 9 are provided on the side walls of the supporting protective layer 8.

[0046] In order to use the guide structure 3021 to push the driving rod 302 to rotate when the pile gripper is pressing the pile downward, a guide structure 3021 is provided at one end of the driving rod 302 away from the locking block 301 and toward the side of the rectangular frame 1. In this embodiment, the guide structure 3021 is an arc-shaped guide surface.

[0047] Working principle of this device:

[0048] First, the device is mounted on the square pile 4, and the locking mechanism 3 is operated to initially lock the square pile 4. The pile driver holds the outer side of the rectangular frame 1, and applies downward force during the pile delivery process, further pushing the driving rod 302 to rotate, and the driving rod 302 rotates to drive the locking block 301 to further push the clamping plate 5 to clamp the square pile 4, thereby preventing the pile driver from slipping during the pile delivery process. After a certain distance is delivered downward, the pile driver releases the device, and under the action of the spiral spring, the clamping plate 5 automatically releases the square pile 4, and the device is moved upward along the square pile 4 for a certain distance, and then the above-mentioned pile pressing operation is continued, until the pile delivery is completed, and the device is removed from the square pile 4.

[0049] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
