[0002] The floating box pile driving arm is a device specially used for pile foundation construction in water, mainly used in projects such as bridges, docks, dams, etc. It is very effective especially when carrying out pile foundation construction in waters such as rivers, lakes or seas. It is internally provided with a pile driving mechanism driven by a hydraulic system, which is used to push the pile body or precast pile into the bottom soil. It can work in an environment with large water flow or large waves, ensuring the stability and reliability of the construction.

[0003] However, the existing locking mechanism for the floating box pile driving arm has the following disadvantages. Since the pile driving head on the floating box pile driving arm of the pile driver is usually connected to the transmission arm through a movable shaft for facilitating the clamping or lifting of the pile body by the pile driving head, when the pile driving head pushes the pile body downward, the movable shaft is prone to drive the pile driving head to rotate and shift left and right, affecting the pile driving quality. Therefore, it is necessary to improve the existing locking mechanism for the floating box pile driving arm. Content of the Utility Model

[0004] The purpose of the utility model is to provide a locking mechanism for a floating box pile driving arm to solve the problem that the pile driving head on the floating box pile driving arm of the existing pile driver on the market is usually connected to the transmission arm through a movable shaft. When the pile driving head pushes the pile body downward, the movable shaft is prone to drive the pile driving head to rotate and shift left and right, affecting the pile driving quality as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A locking mechanism for a floating box pile driving arm, including a transmission arm and a transmission connecting rod.

[0015] 1. A No. 1 locking mechanism and a No. 2 locking mechanism are provided. The electric push rod pushes the mobile frame downward, so that the mobile frame slides downward in the reserved groove of the transmission arm, driving the tooth block of the mobile frame to be stuck on the outer side of the toothed disc, limiting the rotation of the toothed disc, and then limiting the rotation of the rotating shaft, which can prevent the position of the mounting seat.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 3 and Figure 5, the present utility model provides a technical solution: a locking mechanism for a floating box pile driving arm, including a driving arm 1 and a driving connecting rod 2. One end of the driving arm 1 is connected to a first supporting arm 4 through a movable shaft. One end of the first supporting arm 4 far from the driving arm 1 is connected to a second supporting arm 5 through a movable shaft. The driving connecting rod 2 is connected to one side of the first supporting arm 4 through a movable shaft. Hydraulic rods 3 are connected between the driving arm 1 and the first supporting arm 4 and between the first supporting arm 4 and the second supporting arm 5 through movable shafts, and one side of the hydraulic rod 3 is connected to the driving connecting rod 2 through a movable shaft. Below the mounting seat 7 is connected to a machine frame 11 through a movable rod. Sliding grooves 10 are provided on the inner walls of the two sides of the mounting seat 7 close to the machine frame 11. The movable rods at both ends of the machine frame 11 are slidably connected with the sliding grooves 10.

[0027] Please refer to Figures 1 - 3 , one end of the driving arm 1 far from the first supporting arm 4 is connected to a mounting seat 7 through a first locking mechanism 6. The first locking mechanism 6 includes an electric push rod 601, a moving frame 602, a gear disk 603 and a rotating shaft 604. One end of the driving arm 1 movably penetrates through the rotating shaft 604. Gear disks 603 are fixedly connected to both ends of the rotating shaft 604. The rotating shaft 604 is fixedly sleeved between the mounting seat 7. A moving frame 602 is meshed and connected to one side of the gear disk 603. An electric push rod 601 is installed in a reserved groove of the driving arm 1. One end of the electric push rod 601 is connected to the moving frame 602. Second locking mechanisms 8 are installed at both ends of the mounting seat 7. The second locking mechanism 8 includes a limiting frame 801, a bidirectional electric telescopic rod 802, a supporting spring 803 and a locking groove 804. A bidirectional electric telescopic rod 802 is provided in an internal groove of the mounting seat 7. Limiting frames 801 are connected to both ends of the bidirectional electric telescopic rod 802. Supporting springs 803 are sleeved on both ends of the bidirectional electric telescopic rod 802 close to the limiting frames 801. Locking grooves 804 are provided at both ends of the machine frame 11 close to the limiting frames 801. The cross-sectional shape of the limiting frame 801 is "L". Tooth blocks are provided at equal intervals on one side of the moving frame 602 close to the gear disk 603, and the tooth blocks are meshed and connected with the gear disk 603.

[0028] In specific implementation, since the pile driving head on the pontoon pile driving arm of the pile driver is usually connected to the transmission arm 1 through a movable shaft, it is convenient for the pile driving head to clamp or lift the pile body. However, when the pile driving head pushes the pile body downward, the movable shaft is likely to drive the pile driving head to rotate left and right, affecting the quality of pile driving. When the mounting seat 7 and the frame 11 clamp the pile body and push it downward, the electric push rod 601 pushes the movable frame 602 downward, causing the movable frame 602 to slide downward in the reserved groove of the transmission arm 1, driving the tooth block of the movable frame 602 to be stuck in the tooth plate 603. On the outside, the gear disc 603 is restricted from rotating, thereby restricting the rotation of the rotating shaft 604, which can prevent the position of the mounting seat 7. At the same time, the bidirectional electric telescopic rod 802 contracts, so that the bidirectional electric telescopic rod 802 drives the limit frame 801 to approach each other, and the support spring 803 buffers the limit frame 801. One end of the limit frame 801 is inserted into the mounting groove 904 of the frame 11 to restrict the rotation of the frame 11. By locking and limiting the mounting seat 7 and the frame 11, it can prevent the occurrence of deviation and shaking when pushing the pile body, thereby improving the working stability of the pontoon pile driving arm.

[0029] See also Figure 1 and Figures 4 - 7 , a mounting mechanism 9 is provided on the outside of the transmission arm 1, and the mounting mechanism 9 includes a wire harness plate 901, a limiting rod 902, a return spring 903 and a mounting slot 904. A wire harness plate 901 is provided on the outside of the transmission arm 1, and return springs 903 are provided in the built-in grooves at both ends of the wire harness plate 901. Limit rods 902 are provided at both ends of the return spring 903, and the limiting rods 902 are slidably connected to the built-in grooves of the wire harness plate 901. A mounting slot 904 is provided on the side of the transmission arm 1 close to the limiting rod 902, and the inner side of the wire harness plate 901 is provided with equally spaced bayonet sockets, and the cross-sectional shape of the mounting slot 904 is "L"-shaped.

[0030] During specific implementation, since many cables will be installed on the pontoon pile driving arm, these cables lack a limiting structure, resulting in the cables being relatively scattered. The limiting rod 902 can be pulled to make the limiting rods 902 approach each other and squeeze the reset spring 903, and then the wire harness plate 901 is pressed on the outside of the cable, and at the same time, one end of the limiting rod 902 is extended into the installation groove 904, and then the limiting rod 902 is released to make the reset spring 903 rebound and drive the limiting rod 902 to move to both sides, thereby making one end of the limiting rod 902 stuck in the installation groove 904, and the wire harness plate 901 can be quickly installed on the transmission arm 1, and the cables can be separated and limited to prevent the cables from being scattered and entangled, thereby improving the practicality of the pontoon pile driving arm.

[0031] Working principle: When using the locking mechanism for the floating caisson pile driving arm, first, the cable on the transmission arm 1 is limited by the installation mechanism 9, and then the hydraulic rod 3 extends to push the first support arm 4 to rotate. At the same time, the transmission arm 1 rotates, and the transmission connecting rod 2 assists the transmission arm 1 to rotate, so that the mounting seat 7 drives the rack 11 to move, clamp and push the pile body. At the same time, the first locking mechanism 6 and the second locking mechanism 8 limit and lock the mounting seat 7 and the rack 11 to prevent shaking and deviation when pushing the pile body, improving the stability and practicability of the floating caisson pile driving arm. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
