Abstract
Description
Technical Field
[0001] The utility model relates to the field of impact hammer oil pipes, in particular to a movable oil pipe support device. Background Art
[0002] During the construction of offshore wind turbine foundation piles, impact hammers are crucial equipment. Conventional hammer oil pipes are typically moved from the center of the ship's deck to the starboard side of the ship. This method, however, is now pushed and pulled by construction workers with the assistance of a crane. This approach often presents the following major issues:
[0003] First, when the oil pipe of the impact hammer moves on the deck surface, it is easily scratched by sharp parts on the deck surface, causing the oil pipe to burst, shortening the service life of the oil pipe, increasing the frequency of oil pipe replacement, increasing construction costs and greatly reducing construction efficiency.
[0004] Secondly, the hammer's tubing is long and heavy (8 tons total, with the crane supporting approximately 0.5 tons), making it difficult for construction workers to maneuver. Furthermore, when subjected to tension, it sways up and down, left and right, posing a significant safety hazard to nearby operators. This is especially true in offshore construction environments, where weather conditions are unstable and waves are high, and the tubing can swing more violently, increasing the likelihood and severity of accidents. Summary of the Invention
[0005] The technical problem to be solved by the utility model is to provide a movable oil pipe support device, which can effectively protect the oil pipe from being scratched by sharp objects, and at the same time provide flexible mobility and be convenient for operators to use.
[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0007] A movable oil pipe support device includes a vehicle body with a groove on the vehicle body, in which the impact hammer oil pipe is stored; a universal wheel is installed at the bottom end of the vehicle body; or, connecting plates are fixed to the left and right side surfaces of the vehicle body, and slide grooves are fixed at both ends of the connecting plates. The upper ends of the support legs slide in the slide grooves, and the lower ends are equipped with universal wheels through wheel frames. A support plate is connected between the lower ends of the two legs on the same side, and a lifting hydraulic cylinder is installed on the support plate. The piston rod of the lifting hydraulic cylinder is connected to the connecting plate.
[0008] A rubber protective layer is arranged at the corner of the upper end of the vehicle body.
[0009] When the universal wheel is directly installed on the bottom of the vehicle body, the universal wheel is provided with a brake pad.
[0010] A handle is fixed on the outer side of the upper end of the vehicle body.
[0011] There are two groups of connecting plates on each side of the vehicle body and they are spaced apart in an upper and lower arrangement. The sliding grooves at both ends of each group of connecting plates are fixed to the vehicle body and are used for the legs to pass through.
[0012] The utility model provides a movable oil pipe support device, which has the following technical effects:
[0013] 1) Arc-shaped grooves are set on the vehicle body to place the impact hammer oil pipe to prevent the oil pipe from being cut by sharp objects during transfer; at the same time, it prevents the oil pipe from moving freely on the deck when the hull shakes, providing stability and safety to the construction environment.
[0014] 2) By directly setting universal wheels with brake pads on the vehicle body, it is convenient to move, slow down or stop.
[0015] 3) By setting up a relatively liftable vehicle body, the height of the vehicle body can be lowered after the transfer, so that the vehicle body falls directly to the ground, lowering the center of gravity and maintaining stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1
[0025] like Figure 1-3The figure shows a movable oil pipe support bracket, comprising a vehicle body 2 with a recess 7 for storing the hammer oil pipe 6. The recess 7 effectively supports and limits the position of the hammer oil pipe, protecting it from scratches by sharp objects. The recess 7 is 1 meter long, and the hammer oil pipe 6 is 80 meters long. The hammer oil pipe 6 is lifted from the center by a crane, with two-thirds hanging outboard. The remaining one-third is supported and moved by five to six movable oil pipe support brackets at intervals.
[0026] A handle 1 is mounted on one side of the upper end of the vehicle body 2, allowing construction workers to easily push, pull, or control the movement of the device. Universal wheels 4 are mounted on the lower end of the vehicle body 2 via a wheel frame. These wheels facilitate the free movement of the device in multiple directions, facilitating the movement of the oil pipes and providing flexibility and convenience. Brake pads 3 are installed on each universal wheel 4 to slow or stop the movement of the equipment, preventing the oil pipes from moving freely on the deck and providing stability and safety to the construction environment.
[0027] In addition, rubber protective layers 5 are provided at the left and right corners of the upper end of the groove 7 of the vehicle body 2 to prevent the oil pipe from rubbing against the sharp parts of the device, thereby protecting the oil pipe from damage.
[0028] The groove 7 is an arc-shaped groove. The advantages of the arc-shaped groove are: a smooth surface to avoid sharp corners that may scratch the oil pipe; it is convenient for stacking the oil pipe and increases the contact area between the bracket and the oil pipe.
[0029] The impact hammer oil pipe 6 here is bendable, and there are a plurality of them, which are tied together by a safety net.
[0030] Example 2
[0031] like Figure 4-6 As shown, unlike Example 1, Example 2 utilizes a liftable vehicle body 2. Connecting plates 8 are fixed to both sides of the vehicle body 2. Each connecting plate 8 is spaced vertically apart and connected to a chute 9 at both ends. The chute 9 also maintains a fixed connection to the vehicle body 2. Support legs 10 slide in the chute 9. A support plate 11 is connected between the lower ends of the two supporting legs 10 on the same side. A lifting hydraulic cylinder 12 is mounted on the support plate 11, and the piston rod of the lifting hydraulic cylinder 12 is connected to the lower connecting plate 8. Universal wheels 4 are mounted on the lower ends of the supporting legs 10 via wheel frames.
[0032] During the transfer process, the lifting hydraulic cylinder 12 is extended to make the lower end of the vehicle body 2 separate from the deck surface, thereby facilitating the pushing and moving; when reaching the designated position, the lifting hydraulic cylinder 12 can be retracted to make the lower end of the vehicle body 2 fall onto the deck surface, so that the center of gravity of the entire device is lowered, making it more stable, not affected by the shaking of the hull caused by wind and waves, and there is no need to set brake pads 3.
[0033] Here, the four groups of lifting hydraulic cylinders 12 act synchronously and can be driven by a micro hydraulic pump station or a small hydraulic system, which is convenient for direct installation on the vehicle body 2.
