Description

Technical Field

[0001] This utility model relates to the field of cooling water jacket technology for pile driving hammers, and in particular to a reinforced cooling water jacket for a diesel pile driving hammer. Background Technology

[0002] Diesel pile hammers are a relatively new type of pile driving equipment for foundation engineering. Due to their advantages such as large impact energy, high working efficiency, low operating cost and ease of use, they have significant advantages over older drop hammers, steam hammers and guide rod hammers, and have been widely used.

[0003] Currently, conventional cooling water jackets are fixed to the outer wall of the pile driver by welding. During the impact process, the weld may break, resulting in water leakage and reduced heat dissipation. In addition, conventional cooling water jackets are mostly arranged in the form of straight water channels or single spiral circulation water channels. These water channel arrangements often have problems such as poor temperature field uniformity and high flow resistance.

[0004] Therefore, those skilled in the art have provided a reinforced cooling water jacket for a diesel pile driver to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a reinforced cooling water jacket for a diesel pile driver. Through the cooling mechanism, the flow resistance can be reduced to a certain extent, thereby efficiently absorbing the heat generated by the pile driver. Furthermore, through the installation mechanism, the cooling water jacket is embedded into the cylinder body, thus avoiding welding cracks that would reduce the heat dissipation effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A reinforced cooling water jacket for a diesel pile driver includes a cylinder body and a piston sleeve. The cylinder body is provided with a cooling mechanism, and the upper end of the piston sleeve is provided with an installation mechanism.

[0008] The cooling mechanism includes a cooling water jacket. The cooling water jacket has two outlet channels and two inlet channels arranged in a ring inside. A first fixed seat is provided on the upper end face of the cooling water jacket. The first fixed seat has an outlet groove and an inlet groove inside. Two second inlet pipes are symmetrically arranged at the bottom end of the inlet groove. The bottom end of the second inlet pipes passes through the first fixed seat and is connected to the inlet channel. Two outlet channels are symmetrically arranged at the bottom end of the outlet groove and are connected to the outlet channels inside the cooling water jacket. A second fixed seat is provided at the bottom end of the cooling water jacket. The second fixed seat has a return groove inside. Four water inlets are provided on the upper end face of the second fixed seat. The water inlets are connected to the bottom ends of the two inlet channels and the two outlet channels.

[0009] The above technical solution, through the cooling mechanism, can reduce flow resistance to a certain extent, thereby efficiently absorbing the heat generated by the pile driver.

[0010] Furthermore, the installation mechanism includes a third fixed seat, with slots on both sides of the outer wall of the third fixed seat, and cavities on both sides of the upper end of the cylinder body. A spring is installed inside the cavity, and a locking block is connected to one end of the spring. The locking block and the slot are engaged. A fixing plate is installed at the bottom end of the second fixed seat, and a bolt is threaded to the bottom end of the fixing plate. The cooling water jacket is fixed inside the cylinder body by bolts.

[0011] The above technical solution uses an installation mechanism to embed the cooling water jacket into the cylinder body, thereby preventing welding cracks that could lead to a decrease in heat dissipation.

[0012] Furthermore, the upper end face of the first fixed base is provided with an outlet pipe and a first inlet pipe on both sides. The first inlet pipe passes through the outer wall of the first fixed base and extends into the inlet groove, and the outlet pipe passes through the outer wall of the first fixed base and extends into the outlet groove.

[0013] The above technical solution enables the cooling water inside the cooling water jacket to circulate.

[0014] Furthermore, a first buffer pad is provided at the bottom end of the fixing plate;

[0015] The above technical solution prevents damage to the cooling water jacket during impact.

[0016] Furthermore, a lifting lug is provided on the upper end face of the cylinder body;

[0017] The above technical solution allows the cylinder body to be lifted upwards.

[0018] Furthermore, a piston is disposed inside the piston sleeve, and the piston and the cylinder body cooperate with each other;

[0019] The above technical solution involves using a piston to compress air, which is then ignited by an igniter to move the piston sleeve downwards and the cylinder body upwards, thereby driving the column into the ground.

[0020] Furthermore, a second buffer pad is provided at the upper end of the third fixing seat;

[0021] The above technical solution can protect the cooling water jacket.

[0022] Furthermore, the cooling water jacket material is set as a copper-steel water jacket;

[0023] The above technical solution provides high strength for copper-steel, thereby increasing the service life of the water jacket.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a reinforced cooling water jacket for a diesel pile driver. Cooling water is injected into the cooling water jacket through a first inlet pipe and enters the inlet tank. The cooling water then enters two inlet channels through two second inlet pipes. After absorbing the heat generated inside, the cooling water enters the return tank through two water inlets. The cooling water in the return tank then enters the outlet tank through two other water inlets. At this point, it can further absorb the heat generated inside. The cooling water then flows out through the outlet pipe. Through the cooling mechanism, the flow resistance can be reduced to a certain extent, thereby efficiently absorbing the heat generated by the pile driver.

[0026] 2. This utility model proposes a reinforced cooling water jacket for a diesel pile driver. During installation, the cooling water jacket is inserted into the cylinder body. When it reaches the designated position, the spring returns to its original position, causing the locking block to engage in the locking groove, thereby fixing the cooling water jacket into the cylinder body. Then, bolts are used to fix the cooling water jacket to the cylinder body. The first and second buffer pads can protect the cooling water jacket, thereby preventing it from being damaged by impact. Through the installation mechanism, the cooling water jacket is embedded into the cylinder body, thus avoiding the cooling water jacket being welded to the outer wall, which would crack upon impact and reduce the heat dissipation effect.
