Description

Technical Field

[0001] This invention relates to the field of dredging vessel tools, and in particular to a tool for easily installing a high-pressure water jet nozzle sleeve. Background Technology

[0002] The dredger's mud hopper is equipped with a high-pressure water jet. The purpose of the high-pressure water jet is to dilute the mud by flushing it when dumping mud or blowing it onto the bank. Each outlet (180 in total) is equipped with a rubber sleeve. The purpose of the rubber sleeve is to collect the water jet when water is discharged. When the water is stopped, the rubber sleeve automatically closes to prevent mud and sand from flowing into the pipe and causing blockage. The rubber sleeve and the water jet nozzle must be kept sealed.

[0003] However, the gaps between multiple flush nozzles are often quite small, and the flushing sleeves are too rigid. The limited space inside the mud chamber makes it very difficult for workers to install the sleeves on-site after entering the mud chamber. In light of this situation, based on observations of the flush nozzle installation process and principles, and combined with existing ship tools, a tool was developed to facilitate the installation of high-pressure flush nozzle sleeves. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a tool that facilitates the installation of high-pressure water nozzle sleeves.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tool for facilitating the installation of a high-pressure water nozzle sleeve includes a fixing frame and a water nozzle body. The fixing frame is equipped with a lifting mechanism, and a sealing block for engaging with the water nozzle body is placed on the lifting mechanism. A connecting plate is fixed to the upper inner side of the fixing frame via a connecting rod. Two mutually abutting semi-circular shells are rotatably mounted on the connecting plate via a pin. A first torsion spring for driving the semi-circular shells to return to their original rotation is mounted on the pin. A semi-circular seat is movably mounted inside each semi-circular shell, and the two semi-circular seats abut against each other. Each semi-circular seat has a through hole for engaging with the flange bolts of the water nozzle body.

[0007] Preferably, an elastic telescopic rod is fixedly provided on the top inner wall of the semi-circular outer shell, and an arc-shaped plate is fixedly connected to the end of the elastic telescopic rod away from the inner wall of the semi-circular outer shell, and the arc-shaped plate is rotatably connected to the semi-circular seat.

[0008] Preferably, an arc-shaped block is fixed at the bottom of the arc-shaped plate, and an arc-shaped groove for sliding the arc-shaped block is provided at the top of the semi-circular seat. An arc-shaped spring is provided between the inner wall of the arc-shaped groove and the arc-shaped block.

[0009] Preferably, a sliding rod is fixed to the inner wall of the semi-circular outer shell, and a track groove for sliding the sliding rod is provided on the outer wall of the semi-circular seat, and the track groove is spiral in shape.

[0010] Preferably, the bottom of the semi-circular seat is provided with evenly distributed balls, which move against the top wall of the flush nozzle body flange.

[0011] Preferably, both of the semicircular outer shells include a semicircular shell and a lever plate disposed at the end of the semicircular shell. A first pneumatic telescopic rod is fixedly disposed on the lever plate. A force-bearing plate is connected to the end of the first pneumatic telescopic rod away from the lever plate. A second pneumatic telescopic rod is fixedly disposed on the semicircular seat. An air guide pipe is disposed between the first pneumatic telescopic rod and the second pneumatic telescopic rod. A positioning groove is opened on one of the semicircular seats to be inserted into the second pneumatic telescopic rod in the other semicircular seat.

[0012] Preferably, the first pneumatic telescopic rod and the second pneumatic telescopic rod have the same structure, both including an outer tube, a piston slidably connected inside the outer tube, an elastic element disposed between the piston and the inner wall of the outer tube, and an inner rod fixed on the piston. The inner rod of the first pneumatic telescopic rod is connected to the force plate, and the inner rod of the second pneumatic telescopic rod is inserted into the positioning groove.

[0013] Preferably, the lifting mechanism includes a support plate fixed inside the fixed frame, a jack set on the support plate, and a tray fixed on the jack. The sealing block is placed on the tray, and a silicone pad is also provided on the top of the sealing block.

[0014] Preferably, the fixing frame is provided with handles on both sides, the bottom of the handle is provided with a groove, and the outer surface of the handle is covered with a rubber sleeve.

[0015] Preferably, the inner side of the fixing frame is provided with two sets of reinforcing rods, and the outer surfaces of the fixing frame, reinforcing rods and support plate are all coated with anti-rust paint.

[0016] Compared with the prior art, the present invention provides a tool for easily installing high-pressure water nozzle sleeves, which has the following advantages:

[0017] 1. This tool facilitates the installation of high-pressure flush nozzle rubber sleeves. By setting a relatively rotatable semi-circular outer shell, the rotation of the semi-circular outer shell drives the connected semi-circular seat to rotate synchronously. This allows the semi-circular seat to quickly and directly snap onto the flange top of the flush nozzle body. Furthermore, the semi-circular outer shell moves downward relative to the semi-circular seat, and the semi-circular seat automatically rotates relative to the outer flange of the flush nozzle, so that the through hole on the semi-circular seat automatically aligns with the flange bolts. Subsequently, in conjunction with the lifting mechanism, it facilitates the quick docking and installation of the sealing block and the flush nozzle, saving operation time and improving the efficiency of flush nozzle installation.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 9 A tool for facilitating the installation of a high-pressure water nozzle sleeve includes a fixing frame 1 and a water nozzle body 6. The fixing frame 1 is provided with a lifting mechanism, on which a sealing block 5 for engaging with the water nozzle body 6 is placed. A connecting plate 9 is fixedly mounted on the upper inner side of the fixing frame 1 via a connecting rod 8. Two mutually movable and abutting semi-circular shells 10 are rotatably mounted on the connecting plate 9 via a pin. A first torsion spring for driving the semi-circular shells 10 to reset and rotate is mounted on the pin. A semi-circular seat 18 is movably mounted inside each semi-circular shell 10. The two semi-circular seats 18 are movable and abutting each other. Each semi-circular seat 18 has a through hole 181 that engages with the flange bolt of the water nozzle body 6.

[0031] Furthermore, an elastic telescopic rod 19 is fixedly provided on the top inner wall of the semi-circular outer shell 10. An arc-shaped plate 191 is fixedly connected to one end of the elastic telescopic rod 19 away from the inner wall of the semi-circular outer shell 10. The arc-shaped plate 191 is rotatably connected to the semi-circular seat 18.

[0032] Furthermore, an arc-shaped block 1911 is fixedly provided at the bottom of the arc plate 191, and an arc-shaped groove 182 for sliding of the arc-shaped block 1911 is provided at the top of the semi-circular seat 18. An arc-shaped spring 1821 is provided between the inner wall of the arc-shaped groove 182 and the arc-shaped block 1911.

[0033] Furthermore, a slide rod 13 is fixedly provided on the inner side wall of the semi-circular outer shell 10, and a track groove 183 for sliding the slide rod 13 is provided on the outer side wall of the semi-circular seat 18. The track groove 183 is spiral in shape.

[0034] Furthermore, the lifting mechanism includes a support plate 2 fixed inside the fixed frame 1, a jack 3 set on the support plate 2, and a tray 4 fixed on the jack 3. A sealing block 5 is placed on the tray 4, and a silicone pad 12 is also provided on the top of the sealing block 5.

[0035] Specifically, when connecting the sealing block 5 and the flush nozzle body 6, the operator directly pries open the two semi-circular outer shells 10, causing them to separate relative to each other. As the semi-circular outer shell 10 rotates, it drives the connected semi-circular seat 18 to rotate synchronously, facilitating the quick and direct engagement of the semi-circular seat 18 with the flange bolts on the flush nozzle body 6. Subsequently, the semi-circular outer shell 10 will move downwards under its own weight (or can be manually pressed down), compressing the elastic telescopic rod 19. As the semi-circular outer shell 10 moves downwards, it slides within the track groove 183 via the slide rod 13, causing the semi-circular seat 18 to automatically align with the flush nozzle body 6. The flange on the outside of the faucet body 6 rotates, causing the through hole 181 on the semi-circular seat 18 to automatically align with the flange bolt. When the semi-circular seat 18 moves down, the through hole 181 fits onto the outside of the flange bolt. No manual aiming and alignment is required, making the fixing bracket 1 more stable when placed and less prone to shaking. Then, the worker shakes the jack 3, causing the sealing block 5 and the silicone gasket 12 to seal the faucet body 6. The above method not only facilitates on-site installation but also saves time. One person can easily install the flushing sleeve in a few minutes, greatly improving the efficiency of faucet installation.

[0036] Reference Figure 4 As a preferred technical solution of the present invention, the bottom of the semi-circular seat 18 is provided with evenly distributed balls 14, which move against the top wall of the flange of the flush nozzle body 6.

[0037] Specifically, when the semicircular seat 18 rotates relative to the semicircular outer shell 10, the semicircular seat 18 contacts the outer flange of the flush nozzle through the bottom ball bearing 14, reducing the resistance encountered by the semicircular seat 18 during rotation and improving the smoothness of the rotation of the semicircular seat 18.

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As a preferred technical solution of the present invention, each of the two semi-circular shells 10 includes a semi-circular shell and a lever plate 15 disposed at the end of the semi-circular shell. A first pneumatic telescopic rod 151 is fixed on the lever plate 15. A force-bearing plate 152 is connected to the end of the first pneumatic telescopic rod 151 away from the lever plate 15. A second pneumatic telescopic rod 153 is fixed on the semi-circular seat 18. An air guide pipe is disposed between the first pneumatic telescopic rod 151 and the second pneumatic telescopic rod 153. A positioning groove 16 is opened on one of the semi-circular seats 18 to be inserted into the second pneumatic telescopic rod 153 in the other semi-circular seat 18.

[0039] Furthermore, the first pneumatic telescopic rod 151 and the second pneumatic telescopic rod 153 have the same structure, both including an outer tube 17, a piston 171 slidably connected in the outer tube 17, an elastic element 172 disposed between the piston 171 and the inner wall of the outer tube 17, and an inner rod 173 fixed on the piston 171. The inner rod 173 of the first pneumatic telescopic rod 151 is connected to the force plate 152, and the inner rod 173 of the second pneumatic telescopic rod 153 is inserted into the positioning groove 16.

[0040] Specifically, by pressing the force plate 152 on the outside of the lever 15, the first pneumatic telescopic rod 151 is compressed, and the air inside the first pneumatic telescopic rod 151 is introduced into the rod cavity of the second pneumatic telescopic rod 153. The piston 171 inside the second pneumatic telescopic rod 153 is forced to retract the inner rod 173 into the outer tube 17, and the inner rod 173 moves out of the positioning groove 16, releasing the insertion restriction of the second pneumatic telescopic rod 153 on the other semi-circular seat 18. As the force plate 152 continues to be stressed, the force plate 152 applies force to the lever 15, and the two levers 15 move closer to each other, thereby causing the two semi-circular outer shells 10 to... The circular shells are relatively far apart, which facilitates the expansion of the two semi-circular shells 10 and their direct fitting onto the top of the outer flange of the flush nozzle. After the two semi-circular shells 10 drive the semi-circular seat 18 to surround the outer flange of the flush nozzle, no more force is applied to the force plate 152, so that the second pneumatic telescopic rod 153 is reset and inserted into the positioning groove 16 of the other semi-circular seat 18, so that the two semi-circular seats 18 are combined. This prevents the two semi-circular seats 18 from separating when the semi-circular shells 10 move down relative to the semi-circular seats 18 and the slide rod 13 slides inside the track groove 183, which would affect the automatic docking of the through hole 181 of the semi-circular seat 18 with the bolts on the flange.

[0041] Reference Figure 7 As a preferred technical solution of the present invention, the fixed frame 1 is further provided with handles 7 on both sides, the bottom of the handle 7 is provided with a groove, and the outer surface of the handle 7 is covered with a rubber sleeve; specifically, under the action of the handle 7, it is easier for the staff to move the fixed frame 1, making the operation more convenient, the groove is more in line with the fingers and conforms to ergonomics, and the rubber sleeve increases the friction between the palm and the handle 7, making it less slippery during operation and more comfortable.

[0042] Reference Figure 7 As a preferred technical solution of the present invention, the inner side of the fixing frame 1 is provided with two sets of reinforcing rods 11, and the outer surfaces of the fixing frame 1, the reinforcing rods 11 and the support plate 2 are all coated with anti-rust paint; specifically, the anti-rust paint can prevent the fixing frame 1, the reinforcing rods 11 and the support plate 2 from rusting.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
