Description

Technical Field

[0001] This utility model relates to the field of ship pipe fitting processing technology, and in particular to a flexible fastening device for irregularly shaped ship pipe fittings. Background Technology

[0002] Marine pipe fittings are pipes used on ships to connect various mechanical equipment, undertaking fluid transmission tasks, including the transmission of liquids, gases, and solid particles, such as water, oil, and gas, and playing an extremely important function and role. Due to the limited space inside the ship and the special requirements for strength, heat dissipation, and transmission media, various special-shaped pipe fittings have gradually appeared in ship construction. For example, flat oval pipes can enhance coolant flow efficiency while saving installation space; hexagonal, D-shaped, and other special-shaped steel pipes are used for deck supports or frames to improve pressure resistance and reduce weight.

[0003] Currently, various clamping devices can effectively clamp various regular round and square tubes, but they cannot effectively clamp various irregularly shaped pipes for ships with different cross-sectional shapes. Utility Model Content

[0004] This utility model proposes a flexible fastening device for irregularly shaped pipe fittings on ships, which can effectively fasten elliptical pipes, hexagonal pipes, D-shaped pipes or other irregular cross-sectional shapes of ship pipe fittings, and at the same time select the degree of fastening to achieve flexible fixing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible fastening device for irregularly shaped pipe fittings on ships, which can fix fittings with different cross-sectional shapes by adjusting the relative positions of the slider and the clamping block and moving the slider and the clamping block toward the clamping hole by the fixing belt.

[0006] The technical solution to achieve the purpose of this utility model is: a flexible fastening device for irregularly shaped pipe fittings of ships, including a base plate, clamping holes, several clamping components, fixing components, and several supporting legs.

[0007] The clamping assembly includes a guide rail groove on the base plate, a guide rail fixedly installed in the guide rail groove, a slider installed on the guide rail, and a through fixing hole on the part of the slider that extends beyond the base plate. The slider and the clamping block are adjustablely fixed.

[0008] The fixing assembly includes a fixing post fixedly mounted on the base plate, one end of a fixing strap fixed to the fixing post, the other end of the fixing strap passing through all the fixing holes in sequence and finally fixed to the drive shaft, and the drive shaft passing through the through hole on the base plate and connecting to the motor output shaft.

[0009] Furthermore, the upper end of the slider has several bolt holes, and the clamping block has several through bolt holes. The connecting bolts are adapted to the bolt holes on the slider and the clamping block. By fixing different sliders and clamping blocks with the connecting bolts, the relative position of the slider and the clamping block can be adjusted.

[0010] Furthermore, the fixing strap has several fixing strap holes along its length.

[0011] Furthermore, the fixing component also includes a movable column, which is bolt-shaped and equipped with a matching fixing nut; a through fixing groove is opened on the base plate, through which the movable column passes through the base plate and is fixed in a certain position in the fixing groove by the fixing nut. When the fixing nut is loosened, the movable column can slide in the fixing groove; a through movable column slot is opened on the upper part of the movable column, and a pin hole through the movable column is opened on the surface of the movable column slot, and a fixing pin is configured in the pin hole.

[0012] Furthermore, the fixing strap is a flat strip with a width dimension more than 10 times its thickness dimension.

[0013] Furthermore, the base plate and the clamping hole are concentric circles, and the extension line of the guide rail groove passes through the center of the base plate.

[0014] Furthermore, an elastic pad is fixedly installed at the end of the clamping block that is closer to the center of the base plate.

[0015] Furthermore, the fixed column, drive shaft, and movable column are installed in the same fan-shaped area formed by adjacent guide rail grooves, with the fixed column and movable column on the left and right sides of the drive shaft.

[0016] Furthermore, the entire fixing device is a multi-layered structure consisting of a base plate, clamping components, fixing components, and supporting legs spaced apart.

[0017] The advantages of this utility model are:

[0018] Firstly, by rotating the drive shaft, the fixing belt is gradually tightened. The fixing belt drives the slider and clamping block to move towards the clamping hole along with the fixing belt. By adjusting the relative position of the slider and clamping block, pipes of various shapes on ships can be fixed.

[0019] Secondly, different tightening degrees of the fastening band can be selected according to the processing requirements of different pipe fittings to achieve flexible fixing.

[0020] Secondly: By adjusting the position of the movable column to make the fixing band hole coincide with the pin hole, and then passing the fixing pin through, one end of the fixing band is fixed. At this time, even if the motor fails or the power is cut off, it will not affect the fixing of the pipe fitting. Attached Figure Description

[0028] 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.

[0029] like Figures 1 to 2 As shown in the figure, a flexible fastening device for irregularly shaped pipe fittings of ships includes a base plate 1, a clamping hole 2, a clamping assembly, a fixing assembly, and a support leg 6.

[0030] A through clamping hole 2 is opened in the middle of the base plate 1, and several support legs 6 are distributed on the lower end face of the base plate 1. When the clamping device is working, the outfitting part to be processed is placed in the clamping hole 2, and the outfitting part can be fixed by the cooperation of several clamping components and fixing components.

[0031] The clamping assembly includes several guide rail grooves 31 formed in the annular area formed by the base plate 1 and the clamping hole 2, a guide rail 32 fixedly installed in the guide rail groove 31, a slider 33 slidably installed on the guide rail 32, and the slider 33 being able to slide along the corresponding guide rail 32 in the guide rail groove 31; a through fixing hole 37 is formed at the upper part of the slider 33 beyond the base plate 1.

[0032] In one embodiment, the base plate 1 and the clamping hole 2 are concentric circles, and several clamping components are evenly distributed on the base plate 1. The extension line of the guide rail 32 passes through the center of the base plate 1.

[0033] The slider 33 can be adjusted and fixedly mounted on the upper part with the clamping block 34 by means of bolts or pin-type buckles.

[0034] like Figure 4 As shown, in one embodiment, several through bolt holes 35 are opened on the clamping block 34, and corresponding bolt holes 35 are also opened on the top of the slider 33. The clamping block 34 and the slider 33 are fixed by connecting bolts 36. The connecting bolts 36 pass through different bolt holes 35 to achieve adjustable fixing of the clamping block 34 and the slider 33.

[0035] By sliding the slider 33 on the guide rail 32 and adjusting the relative position of the slider 33 and the clamping block 34, the irregular cross-section pipe can be clamped and fixed.

[0036] In order to further reduce the pressure of the clamping assembly on the workpiece, reduce the probability of clamping marks, and increase the friction between the clamping block 34 and the workpiece, an elastic pad 38 is added at the contact end between the clamping block 34 and the workpiece, that is, the end of the clamping block 34 that is closer to the clamping hole 2. The elastic pad 38 can be made of soft elastic materials such as rubber or silicone rubber.

[0037] The fixing assembly includes a fixing belt 41, a fixing post 42, and a drive shaft 48; the fixing post 42 is fixed on the base plate 1.

[0038] The drive shaft 48 passes through the base plate 1, with its lower end connected to the output end of the motor 49 and its upper end fixedly connected to one end of the fixing belt 41.

[0039] The fixing band 41 is long and slender, with one end fixed to the fixing post 42. It then passes sequentially through the fixing holes 37 on all the sliders 33, and finally the other end of the fixing band 41 is fixed to the drive shaft 48. When the motor 49 is started, the drive shaft 48 begins to rotate, and one end of the fixing band 41 begins to wrap around the drive shaft 48. The fixing band 41 gradually tightens, causing the sliders 33 and the clamping blocks 34 to move along the guide rail 32 toward the clamping holes 2 until the pipe is clamped and fixed. During the tightening process, the degree of tightening of the fixing band 41 can be selected to achieve flexible clamping of irregularly shaped pipes. When it is necessary to release the pipe, the motor 49 reverses, and the drive shaft 48 gradually loosens the fixing band, thus realizing the release of the clamping device.

[0040] To prevent unexpected situations such as motor failure or sudden power outage that could affect the performance of the clamping device during pipe fitting processing, in one embodiment, the fixing band 41 is a flat band with a width dimension greater than 10 times its thickness dimension, and has several fixing band holes 411 along its length. At the same time, a movable column 44 is provided on the base plate 1 to cooperate with the fixing band 41 in fixing.

[0041] The movable column 44 is bolt-shaped, and a through fixing groove 43 is opened on the base plate 1. The bolt head of the movable column 44 is on the base plate 1, and the bolt rod passes upward through the fixing groove 43. A fixing nut 50 is installed on the upper part of the movable column 44. In this way, the movable column 44 is adjustablely fixed on the fixing groove 43 of the base plate 1 by the fixing nut 50.

[0042] The upper part of the movable column 44 has a through-hole 45, and a pin hole 46 through the movable column 44 is provided on the surface of the through-hole 45, and a fixing pin 47 is provided.

[0043] After the fixing band 41 passes through all the fixing holes 37, it passes through the through groove 45 of the movable column and is finally fixed on the drive shaft 48. Loosen the fixing nut 50 on the movable column 44, adjust the position of the movable column 44 so that a fixing band hole 411 on the fixing band 41 corresponds to the pin hole 46 of the movable column 44, and use the fixing pin 47 to pass through the pin hole 46 and the fixing band hole 411 to further fix the fixing band 41. Then tighten the fixing nut 50 of the movable column 44. In this way, by fixing the fixing band 41 on the movable column 44, even if there is a problem of motor 49 failure or power failure, it will not affect the clamping device's fixation of the pipe fitting.

[0044] In one embodiment, the fixed column 42, the movable column 44, and the drive shaft 48 are installed in the same fan-shaped area formed by adjacent guide rail grooves 31.

[0045] The specific working method is as follows: Place the pipe to be clamped in the position corresponding to the clamping hole 2, start the motor 49, the motor 49 drives the drive shaft 48 to rotate, as the drive shaft 48 rotates, a part of the fixing belt 41 is gradually wrapped around the drive shaft 48, and the fixing belt 41 is gradually tightened. The fixing belt 41 will drive the slider 33 and the clamping block 34 to move closer to the pipe along the guide rail 32 and gradually clamp it. After the tightness is reached, the motor 49 stops rotating. At this time, loosen the fixing nut 50 on the movable column 44, adjust the position of the movable column 44 so that a certain fixing belt hole 411 corresponds to the pin hole 46 on the movable column 44, and the fixing pin 47 passes through the pin hole 46 and the fixing belt hole 411 of the movable column 44 at the same time.

[0046] After the pipe fitting is processed, remove the fixing pin 47, the motor 49 reverses, the drive shaft 48 reverses, causing the fixing belt 41 to gradually loosen, and the pipe fitting can be removed.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
