Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic pipe processing, and specifically relates to a hydraulic pipe spiral sheath winding device. Background Art

[0002] Hydraulic pipes are essential heavy parts in hydraulic systems. Both ends of the hydraulic pipes are equipped with ferrule joints. The ferrule joints include a fixing ring fixed to the end of the hydraulic pipe and a ferrule nut sleeved on the fixing ring. The ferrule nut is used to connect and tighten with other equipment or pipelines. Since hydraulic pipes are generally made of rubber hoses, which are prone to wear and aging, it is necessary to wrap a spiral sheath around the outside of the hydraulic pipe for protection.

[0003] In the Chinese utility model patent with patent application number 201920013842.9, a winding tool for a spiral protective sleeve on a hydraulic pipe is proposed. The patent mainly has the following problems: First, the winding of the spiral sleeve in the patent still requires manual rotation of the rotating hand wheel. If a relatively long hydraulic pipe is to be wound, two workers are required to complete the winding work. One worker holds the spiral sleeve with one hand and operates the hook with the other hand, and the other worker turns the rotating hand wheel; second, the fixing operation of the hydraulic pipe is relatively cumbersome.

DETAILED DESCRIPTION

[0027] like Figure 1-Figure 4 As shown together, a hydraulic pipe spiral sheath winding device includes a first fixed frame 1, on which a power piece 11 and a clamping claw seat 12 are arranged, the power piece 11 is fixedly mounted on the first fixed frame 1, the clamping claw seat 12 is driven to rotate by the power piece 11, and a clamping mechanism for clamping and fixing the end of the hydraulic pipe 2 is installed on the clamping claw seat 12.

[0028] This embodiment adopts a high-efficiency and low-intensity automated winding method. During the winding process, workers only need to operate the spiral sheath 4. No matter how long the hydraulic pipe 2 is, it can be completed by one person. This not only improves the efficiency of the winding work of the spiral sheath 4 on the hydraulic pipe 2, but also reduces the labor intensity and manpower cost investment of the workers.

[0029] The clamping mechanism includes a plurality of jaws 13 arranged in a ring shape, each jaw 13 is radially slidably installed on the jaw seat 12, a mounting cavity 1201 is provided in the jaw seat 12, one end of each jaw 13 extends into the mounting cavity 1201, and a sliding drive component for driving the jaw 13 to slide is provided inside the mounting cavity 1201.

[0030] like Figure 1-Figure 4 As shown together, the sliding drive assembly includes a rotating screw 1202 extending axially along the clamping jaw seat 12, both ends of the rotating screw 1202 are rotatably mounted on the inner wall of the mounting cavity 1201, a sliding seat 1203 is threadedly mounted on the rotating screw 1202, and a fixing plate 1204 is fixed to one end of each clamping jaw 13 extending into the mounting cavity 1201, and a hinged connecting rod 1205 is hingedly connected between each fixing plate 1204 and the sliding seat 1203, and a stabilizing rod 1206 is hingedly connected between the hinged connecting rod 1205 and the mounting cavity 1201.

[0031] Among them, the sliding drive assembly also includes a first transmission bevel gear 1207 and a second transmission bevel gear 1208 that are meshed with each other. The first transmission bevel gear 1207 is fixedly installed on the rotating screw 1202, and the second transmission bevel gear 1208 is rotatably installed in the clamping claw seat 12 through the shaft 1209. A control rotary block 1210 is rotatably installed on the side wall of the clamping claw seat 12, and the control rotary block 1210 is fixedly connected to the shaft 1209.

[0032] In this embodiment, the control rotary block 1210 or the shaft rod 1209 is limitedly matched with the clamping jaw seat 12 by a tight fit or a spline fit, so that in the absence of external force to twist, the control rotary block 1210 and the shaft rod 1209 cannot rotate in the clamping jaw seat 12, thereby ensuring the clamping, reliability and stability of the hydraulic pipe 2.

[0033] In this embodiment, the control rotary block 1210 can extend out of the outer wall of the clamping jaw seat 12 to directly control the rotation of the control rotary block 1210, or a limiting groove 1211 can be opened on its end surface to use a corresponding wrench to perform a rotation operation on it.

[0034] like Figure 1 and Figure 2 As shown together, a second fixing frame 3 is provided on one side of the first fixing frame 1, and a clamping frame 31 for clamping the other end of the hydraulic pipe 2 is slidably installed on the second fixing frame 3. The clamping frame 31 is slidably installed on the second fixing frame 3 along the extension direction of the hydraulic pipe 2, and a position adjustment component 32 is installed between the second fixing frame 3 and the clamping frame 31.

[0035] In this embodiment, if the hydraulic pipe 2 is relatively long, its tail will swing significantly during the rotation process, seriously affecting the winding quality of the spiral sheath 4 and even causing the winding work to be unable to proceed smoothly. Therefore, when the hydraulic pipe 2 is relatively long, the utility model can use the clamping claws 13 and the clamping frame 31 to fix the two ends of the hydraulic pipe 2 respectively, which not only avoids the situation where the tail of the hydraulic pipe 2 swings significantly and injures workers accidentally, but also avoids the situation where the winding effect of the spiral sheath 4 is affected by the significant swing of the hydraulic pipe 2, thereby ensuring the winding quality and winding efficiency of the spiral sheath 4.

[0036] Moreover, the position adjustment component 32 includes a steering wheel 3201 rotatably mounted on the top of the second fixed frame 3, a tension spring 3202 is wound around the steering wheel 3201, one end of the tension spring 3202 is fixedly connected to the clamping frame 31, and the other end of the tension spring 3202 is fixed to the second fixed frame 3.

[0037] Compared with the traditional winding device that requires adjusting the position of the first fixing frame 1 or the second fixing frame 3, the utility model uses the tensioning spring 3202 to control the tensioning of the hydraulic pipe 2, and no other position adjustment operations are required, thereby greatly simplifying the fixing operation process of the hydraulic pipe 2 and improving the winding efficiency of the spiral sheath 4 on the hydraulic pipe 2.

[0038] A fixing seat 33 is fixed on the top of the second fixing frame 3, and a slide bar 34 is slidably mounted on the fixing seat 33 along the extending direction of the hydraulic pipe 2. A tension spring 3202 is fixedly mounted on one end of the slide bar 34, and a fixing frame 31 is mounted on the other end of the slide bar 34.

[0039] In addition, the fixing frame 31 includes a connecting block 3101 rotatably mounted on the sliding rod 34, a horizontal plate 3102 is fixed on a side wall of the connecting block 3101 away from the sliding rod 34, a vertical plate 3103 is fixed on the top of the horizontal plate 3102, a groove 3104 is provided on the top of the vertical plate 3103 for limiting and locking the hydraulic pipe 2, a vertical rod 3105 is provided between the vertical plate 3103 and the connecting block 3101, and the vertical rod 3105 is fixed to the top of the horizontal plate 3102.

[0040] In this embodiment, the width of the slot 3104 is larger than the diameter of the hydraulic pipe 2 and smaller than the diameter of the clamping nut 21 at the end of the hydraulic pipe 2, thereby achieving the clamping and fixing of the end of the hydraulic pipe 2.

[0041] An anti-slip baffle 35 is hingedly mounted on the connecting block 3101 , and a torsion spring 36 is mounted at the hinge between the anti-slip baffle 35 and the connecting block 3101 .

[0042] In this embodiment, the anti-slip baffle 35 is provided to limit the clamping nut 21 at the end of the hydraulic pipe 2. When the hydraulic pipe 2 is fixed by the clamping frame 31, the worker rotates the anti-slip baffle 35 upward to open it, so that the hydraulic pipe 2 can be smoothly inserted into the slot 3104, and then the anti-slip baffle 35 is released. Under the elastic force of the torsion spring 36, the anti-slip baffle 35 rotates downward and is pressed against the side wall of the clamping nut 21, thereby preventing the hydraulic pipe 2 from falling off from the slot 3104 during rotation.

[0043] The power member 11 is a driving motor, a motor housing of the driving motor is fixed to the top of the first fixing frame 1 , and the clamping jaw seat 12 is fixed to the motor shaft of the driving motor.

[0044] In this embodiment, the control principle and control method of the driving motor are both existing technologies and are well known to ordinary technicians in this field, and will not be described in detail here.

[0045] When the length of the hydraulic pipe 2 is relatively short, the working process of the winding device is as follows:

[0046] In the first step, the ferrule nut 21 at one end of the hydraulic pipe 2 is placed on the clamping jaw 13, and the control rotary block 1210 on the side wall of the clamping jaw seat 12 is turned. The control rotary block 1210 transmits power through the shaft 1209, the second transmission bevel gear 1208 and the first transmission bevel gear 1207, and drives the rotating screw 1202 to rotate. The rotation of the rotating screw 1202 drives the slide seat 1203 to slide, and drives the articulated connecting rod 1205 to rotate inward to control the clamping jaw 13 to clamp inward synchronously, thereby clamping and fixing the ferrule nut 21.

[0047] In the second step, the spiral sheath 4 is wound around the fixed end of the hydraulic pipe 2 for 2-5 turns, and the spiral sheath 4 on the hydraulic pipe 2 is pressed with a pressing hook 5.

[0048] The third step is to start the power piece 11, which drives the clamping jaw seat 12 to rotate. The rotating clamping jaw seat 12 drives the hydraulic pipe 2 to rotate, so that the spiral sheath 4 is automatically wound onto the hydraulic pipe 2.

[0049] Step 4: After winding is completed, remove the hydraulic pipe 2, install a new hydraulic pipe 2, and repeat the above operation.

[0050] When the length of the hydraulic pipe 2 is relatively long, the working process of the winding device is as follows:

[0051] In the first step, the ferrule nut 21 at one end of the hydraulic pipe 2 is placed on the clamping jaw 13, and the control rotary block 1210 on the side wall of the clamping jaw seat 12 is turned. The control rotary block 1210 transmits power through the shaft 1209, the second transmission bevel gear 1208 and the first transmission bevel gear 1207, and drives the rotating screw 1202 to rotate. The rotation of the rotating screw 1202 drives the slide seat 1203 to slide, and drives the articulated connecting rod 1205 to rotate inward to control the clamping jaw 13 to clamp inward synchronously, thereby clamping and fixing the ferrule nut 21.

[0052] In the second step, pull the clamping frame 31 in the direction of the first fixing frame 1, insert the other end of the hydraulic pipe 2 into the slot 3104, use the vertical plate 3103 to clamp the clamping nut 21 at the end of the hydraulic pipe 2, and after loosening the clamping frame 31, under the elastic force of the tensioning spring 3202, the clamping frame 31 slides back and pulls the hydraulic pipe 2 to a horizontal state.

[0053] In the third step, the spiral sheath 4 is wound around the fixed end of the hydraulic pipe 2 for 2-5 turns, and the spiral sheath 4 on the hydraulic pipe 2 is pressed with the pressing hook 5.

[0054] The fourth step is to start the power piece 11, which drives the clamping jaw seat 12 to rotate. The rotating clamping jaw seat 12 drives the hydraulic pipe 2 to rotate, so that the spiral sheath 4 is automatically wound onto the hydraulic pipe 2.

[0055] Step 5. After winding is completed, remove the hydraulic pipe 2, install a new hydraulic pipe 2, and repeat the above operation.

[0056] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
