Description

Technical Field

[0001] The utility model belongs to the field of material conveying devices, and in particular relates to a spiral steel wire rope conveying device. Background Art

[0002] At present, the device for transporting coal sludge slag usually adopts a hose auger. The hose auger in the prior art is shown in a hose spiral conveying device disclosed in the authorization announcement number CN208531477U, which includes a wear-resistant hose, a flexible spiral belt and a driving motor. The flexible spiral belt is arranged in the wear-resistant hose, and the driving motor is connected to and drives the flexible spiral belt to rotate. The wear-resistant hose is provided with a material input port at one end and a material output port at the other end. When working, the driving motor is turned on and drives the flexible spiral belt to rotate. After the solid material enters the wear-resistant hose from the input port at one end of the wear-resistant hose, it is transported to the output port as the flexible spiral belt rotates.

[0003] Coal slime residue contains different components such as dry coal, wet coal, coal slime and coal water, and has a certain viscosity. Therefore, it is easy to adhere to the pipe wall during transportation. With the increase of transportation distance and transportation time, the adhesion of coal slime residue will continue to worsen, which will cause blockage of the hose. Since the diameter of the spiral blade on the flexible spiral belt is matched with the inner diameter of the hose, when the hose is blocked, the spiral blade is subjected to a large torque, and the spiral blade itself is thin, and it is very easy to break when subjected to a large torque, interrupting the normal transportation and production of the hose auger. Utility Model Content

[0004] The utility model provides a spiral steel wire rope conveying device to solve the technical problem that the conveying hose of the existing hose spiral conveying device is easily blocked during long-distance conveying, thereby easily causing the spiral blade to break.

[0005] In order to solve the above problems, the spiral wire rope conveyor provided by the utility model adopts the following technical solutions:

[0006] A spiral wire rope conveyor device, including a conveying hose, a spiral blade and a driving motor;

[0007] A steel wire rope is passed through the center hole of the spiral blade, and the steel wire rope is interference fit with the spiral blade. Both ends of the steel wire rope are connected with rope body joints respectively, and the two rope body joints are respectively connected to the output shaft of the driving motor and the rotating shaft at the feed port of the conveying hose. The two ends of the spiral blade are respectively connected to the two rope body joints; the diameter of the spiral blade is smaller than the diameter of the conveying hose.

[0008] The beneficial effects of the utility model are as follows: after the steel wire rope is connected to the spiral blade, it can provide radial support for the spiral blade and improve the strength of the spiral blade. Since the steel wire rope and the spiral blade are interference fit, the spiral blade will bear the torsion in the direction of conveying materials, and will also bear the friction from the steel wire rope at the center hole. The friction can offset part of the torsion, so that the spiral blade can bear greater torque and reduce the possibility of deformation and breakage of the spiral blade. Secondly, the radial support provided by the steel wire rope for the spiral blade plays a role in preventing the spiral blade from breaking due to excessive bending or uneven force. In addition, in the prior art, the torsion in the direction of conveying materials in the shaftless spiral blade is limited to the cross section of the spiral blade, the force area is small, the torsion strength of the spiral blade is large, and it is easy to break. After the steel wire rope is connected to the spiral blade, when the spiral blade rotates, the torsion area on the cross section includes both the cross-sectional area of ​​the spiral blade and the cross-sectional area of ​​the steel wire rope, so that the spiral blade can bear greater torque and rotation speed. Moreover, since the diameter of the spiral blade is smaller than the diameter of the conveying hose, there is a certain gap between the spiral blade and the conveying hose, through which large particles can pass. When the spiral blade and the wire rope rotate together under the drive of the drive motor, they can revolve under the rotational inertia, which can stir and disperse the agglomerated materials, thereby preventing blockage in the conveying hose.

[0009] Furthermore, the ratio between the diameter of the spiral blade and the diameter of the conveying hose is 2:3.

[0010] Beneficial effect: Different from the prior art in which the diameter of the conveying hose matches that of the spiral blade, in the present application, the diameter of the spiral blade is reduced, and the gap between the spiral blade and the tube wall of the conveying hose is more than 3 times larger than the maximum particle diameter of the conveyed material, so that the amount of material passing through the same cross-section is smaller than the cross-sectional area of ​​the conveying hose, and the instantaneous amount of material in the same cross-section at the same time is reduced, thereby avoiding the accumulation of material in the conveying hose.

[0011] Furthermore, the helix angle and blade inclination angle of the spiral blade are both inclined toward the conveying direction.

[0012] Beneficial effects: It facilitates the transportation and lifting of materials in the conveying hose, reduces the occurrence of material jamming in the conveying hose, and improves the conveying efficiency.

[0013] Furthermore, the delivery hose is a rubber tube.

[0014] Beneficial effects: The rubber tube can withstand the severe friction and heat generated by the friction with the tube wall during the transportation of a large number of particles and abrasive substances in the coal sludge, slowing down the aging of the conveying hose and making it more durable.

[0015] Furthermore, the rope body joint is provided with a coaxial first connecting hole and a second connecting hole, the first connecting hole is used to insert the wire rope, and the second connecting hole is used to connect with the output shaft or rotating shaft of the driving motor. The rope body joint is also provided with a radial through hole communicating with the second connecting hole, and the radial through hole is used to penetrate a fixing part to connect the rope body joint with the output shaft or rotating shaft of the driving motor.

[0016] Beneficial effects: It facilitates the transmission connection between the wire rope and the output shaft and the rotating shaft of the driving motor, and securely fixes the wire rope and the rope body joint to prevent the wire rope from falling off the output shaft or the rotating shaft of the driving motor when the wire rope is driven and rotated by the driving motor.

[0017] Furthermore, a positioning plate is connected to the rope body joint, and both ends of the spiral blade are welded to the positioning plate through a connecting rod.

[0018] Beneficial effect: It is convenient to connect the spiral blade and the wire rope with the rotating shaft and the output shaft of the driving motor into a whole. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0032] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0033] The embodiment of the spiral wire rope conveyor provided by the utility model:

[0034] like Figure 1 As shown, the spiral wire rope 1 conveying device can convey materials such as dry coal, wet coal, coal slime, coal water, etc., and includes a conveying hose 3, a spiral blade 2, a wire rope 1 and a driving motor.

[0035] The delivery hose 3 is made of wear-resistant rubber material. A copper feed port 4 is provided on the delivery hose 3 , and a rubber tube copper joint 5 is provided at the copper feed port 4 and at the other end.

[0036] The spiral blade 2 is made of manganese steel alloy, has high strength, and is arranged in the delivery hose 3. Figure 2As shown, the spiral pitch angle and blade inclination angle of the spiral blade 2 are both inclined toward the conveying direction. The steel wire rope 1 passes through the center hole of the spiral blade 2, and the steel wire rope 1 and the spiral blade 2 are interference fit, so as to be connected together. In the prior art shaftless spiral blade, the torsion in the direction of conveying materials is only limited to the cross section of the spiral blade 2, and the force-bearing area of ​​the torsion is small. The torsion strength borne by the spiral blade 2 is large, and it is easy to break. In the present application, after the steel wire rope 1 is connected to the spiral blade 2, while retaining the bending ability of the conveying device, the cross section of the spiral blade 2 and the steel wire rope 1 that bears the torsion in the direction of conveying materials includes the cross section, which significantly increases the area of ​​the cross section that bears the torsion, thereby significantly reducing the torsion strength borne by the spiral blade 2, and improving the overall structural strength of the spiral blade 2, so that the spiral blade 2 can withstand greater torque and rotation speed.

[0037] The length of the steel wire rope 1 is greater than that of the spiral blade 2 . Both ends of the steel wire rope 1 and the spiral blade 2 pass through two rubber tube copper joints 5 respectively. Both ends of the steel wire rope 1 are located outside the two ends of the spiral blade 2 .

[0038] The diameter of the delivery hose 3 is larger than the diameter of the spiral blade 2. In this embodiment, the ratio of the diameter of the delivery hose 3 to the diameter of the spiral blade 2 is 3:2. Of course, in other embodiments, the ratio of the diameter of the delivery hose 3 to the diameter of the spiral blade 2 can also be 110:80. With such a ratio, a large gap will be left between the spiral blade 2 and the tube wall of the delivery hose 3 for large particles to pass through.

[0039] like Figure 3 and Figure 4 As shown, after the steel wire rope 1 and the spiral blade 2 are connected, in addition to rotating together under the drive of the driving motor, due to the characteristics of the conveying hose 3 and the steel wire rope 1 and the spiral blade 2 located in the conveying hose 3 without structural support, the steel wire rope 1 and the spiral blade 2 will rotate in the conveying hose 3 under the action of their own gravity and inertia, playing the role of stirring and cutting the agglomerated materials, so that the conveying hose 3 is not easily blocked. Moreover, since the ratio of the diameter of the conveying hose 3 to the diameter of the steel wire spiral structure is 3:2, the gap between the spiral blade 2 and the tube wall of the conveying hose 3 is more than 3 times larger than the maximum particle diameter of the conveyed material. In addition, unlike the case where the diameter of the conveying hose 3 and the spiral blade 2 match in the prior art, in this application, the diameter of the spiral blade 2 is reduced, so that the amount of material passing through the same cross section is less than the cross-sectional area of ​​the conveying hose 3, and the instantaneous amount of material in the same cross section at the same time is reduced, thereby avoiding the accumulation of materials in the conveying hose 3.

[0040] like Figure 5 and Figure 6As shown, the two ends of the wire rope 1 are connected to the rope body joints 6, which are respectively connected to the output shaft of the driving motor and the rotating shaft 12 at the feeding port of the conveying hose 3, and the two ends of the spiral blade 2 are respectively connected to the two rope body joints 6. Figure 5 As shown, a coaxial first connection hole 7 and a second connection hole 8 are provided in the rope body joint 6. The first connection hole 7 is used to insert the steel wire rope 1, and the second connection hole 8 is used to plug with the output shaft or the rotating shaft 12 of the driving motor. The rope body joint 6 is also provided with a radial through hole 10 that communicates with the second connection hole 8. The rope body joint 6 close to the driving motor is connected to the output shaft of the driving motor by inserting a locking pin in the radial through hole 10, and the rope body joint 6 close to the rotating shaft 12 is connected to the rotating shaft 12 by inserting a U-bolt 9 in the radial through hole 10. A positioning plate 13 is connected to the rope body joint 6, and the two ends of the spiral blade 2 are welded to the positioning plate 13 through a connecting rod 11. Of course, in other embodiments, the connecting rod 11 can also be directly welded to the rope body joint 6, and the positioning plate 13 is not required in this case.

[0041] The structure of the rope body joint 6 is as follows Figure 7 As shown, during installation, the position where the steel wire rope 1 is inserted into the rope body joint 6 needs to be squeezed on a corresponding squeezing device, so that the steel wire rope 1 and the rope body joint 6 are firmly fixed, such as Figure 8 As shown, after extrusion, an indentation 14 is generated on the surface of the cable body joint 6 .

[0042] When using the shaftless spiral blade of the prior art, if the material conveyed in the conveying hose 3 is blocked, and the driving motor continues to drive the shaftless spiral blade to rotate, the spiral blade 2 will be subjected to the torsion in the conveying material direction, axially squeezing the spiral blade 2, which is easy to cause the spiral blade 2 to deform or even break. Fig. 9 As shown, while the spiral blade 2 is subjected to the torsion in the direction of conveying materials, it is also subjected to the friction force from the wire rope 1 at the center hole. The friction force can offset part of the torsion, thereby enabling the spiral blade 2 to withstand greater torque and reduce the possibility of deformation and breakage of the spiral blade 2. Secondly, the radial support provided by the wire rope 1 for the spiral blade 2 plays a role in preventing the spiral blade 2 from breaking due to excessive bending or uneven force. In addition, in the prior art shaftless spiral blade, the torsion in the direction of conveying materials is limited to the cross-section of the spiral blade 2, and the force-bearing area is small. The torsion strength borne by the spiral blade 2 is large and it is easy to break. After the wire rope 1 is connected to the spiral blade 2, when the spiral blade 2 rotates, the torsion area borne on the cross-section includes both the cross-sectional area of ​​the spiral blade 2 and the cross-sectional area of ​​the wire rope 1, thereby enabling the spiral blade 2 to withstand greater torque and rotation speed.
