Description

Technical Field

[0001] This utility model relates to the field of piling vessel technology, specifically to a sand pile holding device for a piling vessel. Background Technology

[0002] A piling vessel is a vessel used for piling operations on water, widely used in bridge, dock, and water conservancy engineering construction. The sand pile holding device used on a piling vessel is a device used to fix and stabilize the pile, mainly through a mechanical structure to hold the pile tightly to prevent it from swaying or shifting in the water.

[0003] The invention discloses a sand pile holding device based on a piling vessel, authorized by announcement number CN218562345U. This utility model utilizes a ring frame, rotating arms, clamping guide wheels, rotating collars, and transmission worm gears in combination. A servo motor drives the transmission worm gears to mesh with the rotating collars, which rotate along the ring frame and mesh with the ends of multiple rotating arms. This causes the multiple rotating arms to swing and hold and lock the sand piles. The use of a motor as the drive eliminates the need for subsequent maintenance of hydraulic cylinders and hydraulic pipelines. Its overall wiring is flexible and easy to operate, meeting the needs of practical use.

[0004] The efficiency of existing technologies still needs to be improved. The pile clamping device is fixed to the outside of the sand pile by attaching it from the top or bottom of the sand pile. This makes it impossible for the pile clamping device to quickly detach from the outside of the sand pile, and it is also impossible for the pile clamping device to quickly clamp and fix the next sand pile. This still affects the construction efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a sand pile holding device for piling vessels, which solves the problem in the prior art that it is impossible to quickly detach from the outside of the sand pile.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sand pile holding device for piling vessels, including a fixing mechanism, and further comprising: A pile-holding mechanism located at one end of the fixed mechanism and a clamping mechanism located inside the pile-holding mechanism; The pile-holding mechanism includes a first hydraulic cylinder installed on one end of the inner side of the fixed mechanism. A movable seat is fixedly installed on one end of the piston rod of the first hydraulic cylinder. A first traction plate and a second traction plate are rotatably installed on the top and bottom of the inner side of the movable seat, respectively. A first clamp is provided on the end of the first traction plate away from the movable seat, and a second clamp is provided on the end of the second traction plate away from the movable seat. The first clamp and the second clamp are rotatably connected. The clamping mechanism includes clamping plates, four of which are respectively disposed inside the first clamp and the second clamp, and a second hydraulic cylinder is disposed on the outside of the clamping plates.

[0007] Preferably, the fixing mechanism includes a mounting plate, with two mounting bolts threaded into both sides of the mounting plate, a fixing rod fixedly mounted on the outer wall of one end of the mounting plate, and a controller fixedly mounted on the top end of the fixing rod.

[0008] Preferably, a fixing seat is fixedly installed at the end of the fixing rod away from the mounting plate. The fixing seat is located on the outside of the position where the first clamp and the second clamp meet, and the fixing seat is rotatably connected to the first clamp and the second clamp.

[0009] Preferably, the inner wall of the fixed rod is provided with an installation groove, one end of the inner wall of the installation groove is fixedly connected to the first hydraulic cylinder, and the inner wall of the installation groove is slidably connected to the outer wall of the movable seat.

[0010] Preferably, a first connecting seat is fixedly installed on the outer side of the first clamp, and the first connecting seat is rotatably connected to the end of the first traction plate away from the movable seat. A second connecting seat is fixedly installed on the outer side of the second clamp, and the second connecting seat is rotatably connected to the end of the second traction plate away from the movable seat.

[0011] Preferably, the outer walls of the first clamp and the second clamp are respectively fixedly connected to four second hydraulic cylinders, and the piston rods of the second hydraulic cylinders are fixedly mounted with connecting plates, and connecting bolts are threaded into both sides of the connecting plates.

[0012] Preferably, the outer side of the clamping plate is threaded to the outer wall of two adjacent connecting bolts, and a protective pad is fixedly installed on the inner side of the clamping plate.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: The first hydraulic cylinder moves the movable seat, which, under the traction of the first and second traction plates, rotates the first and second clamps inside the fixed seat. This allows the first and second clamps to easily open or close, detaching them from the sand pile. Simultaneously, the second hydraulic cylinder drives the clamping plate to hold and fix the sand pile. This allows the device to easily hold and fix the sand pile, ensuring its stability during construction. It also allows the device to easily fix the next sand pile, significantly reducing the time for fixing and releasing individual sand piles, enabling rapid pile replacement and improving work efficiency.

[0014] The movement of the movable seat is limited by the mounting slot, ensuring its stability during movement. The connection between the first traction plate and the first connecting seat, and the connection between the second traction plate and the second connecting seat, allows the movement of the movable seat to stably drive the first and second clamps to rotate within the fixed seat, thus securely fixing the sand pile. The same device can accommodate sand piles of different diameters within a certain size range, improving the equipment's versatility and applicability, and reducing downtime caused by changing to specialized clamps for different sand pile specifications.

[0015] The mounting plate can be installed as a whole at the corresponding work position on the piling vessel, making it easy to retrofit and modify existing vessels. Attached Figure Description

Detailed Implementation

[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] This utility model provides, for example Figure 1 The illustrated sand pile holding device for a piling vessel includes a fixing mechanism 1, a pile holding mechanism 2 disposed at one end of the fixing mechanism 1, and a clamping mechanism 3 disposed inside the pile holding mechanism 2.

[0025] To facilitate easy detachment of the device from the outside of the sand pile, such as Figure 1-2 and Figure 4 As shown, the pile clamping mechanism 2 includes a first hydraulic cylinder 201 installed on one end of the inner side of the fixed mechanism 1. A movable seat 202 is fixedly installed on one end of the piston rod of the first hydraulic cylinder 201. A first traction plate 203 and a second traction plate 206 are rotatably installed on the top and bottom of the inner side of the movable seat 202, respectively. A first clamp 205 is provided at the end of the first traction plate 203 away from the movable seat 202, and a second clamp 208 is provided at the end of the second traction plate 206 away from the movable seat 202. The first clamp 205 and the second clamp 208 are rotatably connected. When the first hydraulic cylinder 201 works, it drives the movable seat 202 to move, which can drive the first traction plate 203 and the second traction plate 206 to expand outward or contract inward, and thus drive the first clamp 205 and the second clamp 208 to unfold or close, so that it can easily clamp the sand pile, and can also easily detach from the outside of the sand pile, so that the pile clamping mechanism 2 can quickly fix different sand piles.

[0026] To ensure the stability of the sand piles during construction, such as Figure 1-2 and Figure 5 As shown, the clamping mechanism 3 includes clamping plates 303. Four clamping plates 303 are respectively disposed inside the first clamp 205 and the second clamp 208. A second hydraulic cylinder 301 is disposed outside the clamping plates 303. The second hydraulic cylinder 301 drives the clamping plates 303 to move, so that the four clamping plates 303 inside the first clamp 205 and the second clamp 208 can clamp and fix the sand pile. The four clamping plates 303 are arranged in a ring with equal spacing when the first clamp 205 and the second clamp 208 are closed. The sand pile can be clamped and fixed by the four clamping plates 303, so that the device can stably fix the sand pile and keep the sand pile stable during construction.

[0027] To ensure stable installation and fixation of the pile clamping mechanism 2, such as Figure 1-4As shown, the fixing mechanism 1 includes a mounting plate 101. Two mounting bolts 102 are threaded onto both sides of the mounting plate 101. A fixing rod 103 is fixedly mounted on the outer wall of one end of the mounting plate 101. A controller 106 is fixedly mounted on the top end of the fixing rod 103. A fixing seat 104 is fixedly mounted on the end of the fixing rod 103 away from the mounting plate 101. The fixing seat 104 is located outside the junction of the first clamp 205 and the second clamp 208, and is rotatably connected to the first clamp 205 and the second clamp 208. A fixed shaft is fixedly inserted into the inner side of the fixed base 104. The first clamp 205 and the second clamp 208 are both rotatably sleeved on the outside of the fixed shaft, allowing them to rotate outside the fixed shaft. The mounting plate 101 can be fixed by threading the mounting bolt 102 into the inner wall of the mounting plate 101 and threading it to the mounting part. The first clamp 205 and the second clamp 208 can be installed and fixed by the fixed base 104. The working and operation of the pile clamping mechanism 2 and the clamping mechanism 3 can be controlled by the controller 106.

[0028] To ensure the stable operation of the pile-holding mechanism 2, such as Figure 2-4 As shown, the inner wall of the fixed rod 103 has a mounting groove 105. One end of the inner wall of the mounting groove 105 is fixedly connected to the first hydraulic cylinder 201, and the inner wall of the mounting groove 105 is slidably connected to the outer wall of the movable seat 202. A first connecting seat 204 is fixedly installed on the outer side of the first clamp 205. The first connecting seat 204 is rotatably connected to the end of the first traction plate 203 away from the movable seat 202. A second connecting seat 207 is fixedly installed on the outer side of the second clamp 208. The second connecting seat 207 is rotatably connected to the end of the second traction plate 206 away from the movable seat 202. The mounting groove 105 can... The first hydraulic cylinder 201 is installed and fixed. The controller 106 causes the first hydraulic cylinder 201 to drive the movable seat 202 to move along the inner wall of the mounting groove 105. Through the rotational connection between the first traction plate 203 and the first connecting seat 204 and the rotation between the second traction plate 206 and the second connecting seat 207, the movable seat 202 can drive the first clamp 205 and the second clamp 208 to open or close, so that the first clamp 205 and the second clamp 208 can easily fix the sand pile, and at the same time, they can easily detach from the outside of the sand pile.

[0029] In order to ensure that the clamping mechanism 3 stably clamps and fixes the sand pile, such as Figure 2 and Figure 4-5As shown, the outer walls of the first clamp 205 and the second clamp 208 are respectively fixedly connected to two second hydraulic cylinders 301 on the same side. A connecting plate 302 is fixedly installed on the piston rod of the second hydraulic cylinder 301. Connecting bolts 304 are threaded into both sides of the connecting plate 302. The outer side of the clamping plate 303 is threadedly connected to the outer walls of two adjacent connecting bolts 304. A protective pad 305 is fixedly installed on the inner side of the clamping plate 303. The first clamp 205 and the second clamp 208 can install and fix four second hydraulic cylinders 301. The connecting bolts 304 are threaded into the inner wall of the connecting plate 302 and threadedly connected to the outer side of the clamping plate 303, so that the connecting plate 302... The clamping plates 303 are tightly connected, allowing the second hydraulic cylinder 301 to stably move the clamping plates 303. The controller 106 causes the second hydraulic cylinder 301 to move the clamping plates 303, so that the four clamping plates 303 can clamp and fix the sand pile. At the same time, the protective pad 305 can protect the contact position between the clamping plates 303 and the sand pile. The first clamp 205 and the second clamp 208 are sleeved on the outside of the sand pile and do not directly contact the sand pile. They only play a limiting role to prevent the sand pile from tilting. Then, the four second hydraulic cylinders 301 drive the four clamping plates 303 to clamp the sand pile.

[0030] During sand pile construction, the pile clamping device can be installed and fixed by threading the mounting bolts 102 into the inner wall of the mounting plate 101 and connecting them to the installation location. The controller 106 drives the first hydraulic cylinder 201 to move the movable seat 202 along the inner wall of the mounting groove 105, thereby causing the first traction plate 203 and the second traction plate 206 to retract inwards. Through the rotational connection between the first traction plate 203 and the first connecting seat 204, and the rotational connection between the second traction plate 206 and the second connecting seat 207, the first clamp 205 and the second clamp 208 can rotate inside the fixed seat 104, changing from an extended state to a closed state, so that the first clamp 205 and the second clamp 208 are on the outside of the sand pile. Then, the controller 106 extends the four second hydraulic cylinders 301. The connection between the connecting plate 302 and the clamping plate 303 allows the four clamping plates 303 to clamp and fix the outer wall of the sand pile. Simultaneously, the protective pad 305 on the inner side of the clamping plate 303 protects the contact point between the clamping plate 303 and the sand pile, thus enabling the device to stably clamp and fix the sand pile, keeping it stable during construction. After one sand pile is completed, the four second hydraulic cylinders 301 retract, separating the clamping plate 303 from the sand pile. Simultaneously, the first hydraulic cylinder 201 retracts, separating the first clamp 205 and the second clamp 208 from the outside of the sand pile. By repeating the above operations, the next sand pile can be easily fixed, thereby improving the efficiency of sand pile construction. This embodiment specifically solves the problem of low sand pile construction efficiency caused by the inability of the existing pile clamping device to easily detach from the outside of the sand pile.

[0031] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
