Description

Technical Field

[0001] The utility model relates to the technical field of cage weaving machines, in particular to a rib-threading pipe quick disassembly and assembly structure of a cage weaving machine. Background Art

[0002] Cage weaving machines are widely used in many fields, such as construction, agriculture, etc. In the field of construction, wire mesh cages produced by cage weaving machines are often used as steel cages in concrete to enhance the strength and stability of concrete. The reinforcing plate of the cage weaving machine is an important component of the cage weaving machine, which is used to thread steel bars in the process of weaving steel cages. The reinforcing plate usually has one or more perforations, which are designed to allow the steel bars to pass smoothly. The shape and size of the perforations may vary depending on the model and specifications of the cage weaving machine, but the basic function is the same, that is, to ensure that the steel bars can pass through accurately and quickly according to the predetermined path. For example, the "Traction Device for Steel Cage Rolling Welding Machine" with application number CN201811384471.1 discloses this cage weaving machine structure.

[0003] However, at present, the rib-threading tubes on the cage weaving machine are mostly assembled and disassembled by nuts, that is, external threads are turned on the rib-threading tubes and fixed to the rib-threading plate by nuts. The disassembly and assembly process is relatively cumbersome, and the installation and replacement of the rib-threading tubes both take a certain amount of time, which reduces the processing efficiency of the cage weaving machine production line. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fast disassembly structure of a reinforcing tube of a cage weaving machine, which can effectively solve the problem of long disassembly time and difficulty of disassembly of the reinforcing tube, in view of the current status of the prior art.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a rib-penetrating tube quick disassembly and assembly structure, comprising:

[0006] A rib plate having perforations therein;

[0007] A rib-penetrating tube, which is inserted into the perforation of the rib-penetrating plate;

[0008] The outer peripheral wall of the rib-piercing tube is provided with a limiting protrusion and an axial limiting protrusion both protruding radially outward, and a clearance groove for the limiting protrusion to pass through is provided at the outer peripheral edge of the perforation, and the limiting protrusion can pass through the clearance groove and has a locked state and an unlocked state as the rotation position of the rib-piercing tube changes:

[0009] In the locked state, the limiting protrusion of the rib-penetrating tube is staggered with the clearance groove in the axial direction and abuts against the side of the outer peripheral edge of the perforation of the rib-penetrating plate away from the axial limiting protrusion, and the axial limiting protrusion of the rib-penetrating tube directly or indirectly abuts against the other side of the outer peripheral edge of the perforation of the rib-penetrating plate;

[0010] In the unlocked state, the limiting protrusion of the rib-penetrating tube is axially opposite to the clearance groove and can withdraw from the clearance groove.

[0011] In general, the axial positioning of the rib-penetrating tube relative to the rib-penetrating plate can be achieved by directly abutting the limiting protrusion and the axial limiting protrusion of the rib-penetrating tube against the opposite sides of the rib-penetrating plate. However, considering the processing accuracy of the rib-penetrating tube, such as the high requirement for setting the distance size between the limiting protrusion and the axial limiting protrusion, and after frequent disassembly and assembly, it is also easy to cause the rib-penetrating tube positioning failure problem (such as the rib-penetrating tube positioning is not firm and easy to shake) due to the wear of the limiting protrusion and the axial limiting protrusion of the rib-penetrating tube. For this reason, a spring is also sleeved on the outside of the rib-penetrating tube, and the spring is located between the limiting protrusion and the axial limiting protrusion. In the locked state, one end of the spring abuts against the outer peripheral edge of the through hole of the rib-penetrating plate, and the other end abuts against the axial limiting protrusion, so that the axial limiting protrusion of the rib-penetrating tube always has a tendency to move away from the rib-penetrating plate.

[0012] As an improvement, the through hole is circular, and the diameter of the spring is larger than the diameter of the through hole.

[0013] In order to achieve effective position limiting cooperation with the spring and ensure uniform axial force on the rib-penetrating tube, the outer peripheral wall of the rib-penetrating tube has a retaining ring structure protruding radially outward, which constitutes the axial position limiting protrusion. It is conceivable that the axial position limiting protrusion can also be a plurality of retaining block structures sequentially arranged along the circumference of the rib-penetrating tube.

[0014] In order to ensure the reliability of positioning, the limiting protrusion is in the shape of a long strip and is arranged to extend along the axial direction of the rib-piercing tube. The long strip-shaped limiting protrusion cooperates with the clearance groove to also play a guiding role, thereby improving the convenience of disassembly and assembly of the rib-piercing tube.

[0015] In order to prevent the rib-penetrating tube from reciprocating or shaking when not in use, the distance between the limiting protrusion and the axial limiting protrusion in the axial direction of the rib-penetrating tube is less than or equal to the length of the spring in the natural state.

[0016] In order to ensure the overall strength of the rib-penetrating tube, the limiting protrusion and the axial limiting protrusion are connected to the outer peripheral wall of the main body of the rib-penetrating tube by welding.

[0017] Compared with the prior art, the utility model has the following advantages: since a limiting protrusion and an axial limiting protrusion are provided on the rib-piercing tube and a clearance groove is provided on the rib-piercing plate, after the rib-piercing tube passes through the through hole of the rib-piercing plate and rotates a certain angle, the limiting protrusion and the axial limiting protrusion on the rib-piercing tube can correspond to the opposite sides of the outer peripheral edge of the through hole, thereby realizing the fixation of the rib-piercing tube relative to the rib-piercing plate; when the rib-piercing tube needs to be disassembled, the rib-piercing tube is rotated to a position where its limiting protrusion and the clearance groove are relative to each other in the axial direction, and then the clearance groove can be withdrawn to remove the rib-piercing tube; this disassembly and assembly structure of the rib-piercing tube is easy to operate, simplifies the disassembly and assembly process of the rib-piercing tube, and shortens the disassembly and assembly of a single rib-piercing tube to about 20 seconds, effectively solving the problem of long disassembly and assembly time and difficulty in disassembly and assembly of the rib-piercing tube.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0025] Figure 1-Figure 5A preferred embodiment of the rib-penetrating tube quick disassembly and assembly structure of the cage weaving machine of the utility model is shown. The rib-penetrating tube quick disassembly and assembly structure includes a rib-penetrating plate 20 and a rib-penetrating tube 30 connected to the rib-penetrating plate 20. Specifically, a plurality of through holes 21 arranged in sequence and spaced apart are distributed on the rib-penetrating plate 20, and each through hole 21 penetrates the front and rear opposite sides of the rib-penetrating plate 20. Each through hole 21 on the rib-penetrating plate 20 is circular, and a clearance groove 210 intersecting the through hole 21 is also provided at the outer peripheral edge of each through hole 21, and the clearance groove 210 also corresponds to penetrate the front and rear opposite sides of the rib-penetrating plate 20.

[0026] See also Figure 4 and Figure 5 , the main body of the rib-penetrating tube 30 is also a circular tube. The outer peripheral wall of the rib-penetrating tube 30 is provided with a limiting protrusion 31 and an axial limiting protrusion 32, wherein the limiting protrusion 31 and the axial limiting protrusion 32 both protrude radially outward, and the limiting protrusion 31 and the axial limiting protrusion 32 are also spaced a certain distance apart in the axial direction of the rib-penetrating tube 30. The above-mentioned axial limiting protrusion 32 is a retaining ring structure protruding radially outward from the outer peripheral wall of the rib-penetrating tube 30. The above-mentioned limiting protrusion 31 is in the shape of an elongated strip and is arranged to extend in the axial direction of the rib-penetrating tube 30. The elongated limiting protrusion 31 cooperates with the clearance groove 210 to also play a guiding role, thereby improving the convenience of disassembly and assembly of the rib-penetrating tube 30. The above-mentioned limiting protrusion 31 and the axial limiting protrusion 32 are both connected to the outer peripheral wall of the main body of the rib-penetrating tube 30 by welding, thereby ensuring the overall strength of the rib-penetrating tube 30.

[0027] A spring 40 is also sleeved outside the rib-penetrating tube 30, and the spring 40 is located between the limiting protrusion 31 and the axial limiting protrusion 32. The distance between the limiting protrusion 31 and the axial limiting protrusion 32 in the axial direction of the rib-penetrating tube 30 is recorded as L, and the length of the spring 40 in the natural state is recorded as L1, wherein L≤L1, thereby preventing the rib-penetrating tube 30 from reciprocating or shaking when not in use. On the other hand, the diameter of the spring 40 of this embodiment is larger than the diameter of the through hole 21 on the rib-penetrating plate 20, so that one end of the spring 40 can be against the outer peripheral edge of the through hole 21 of the rib-penetrating plate 20.

[0028] See also Figure 3 The rib plate 20 has a shaft 22 perpendicular to its main body. When installing the rib tube 30, the rib plate 20 can be placed on a base 10. Specifically, the top of the base 10 has a triangular bracket 11, and the top corner of the bracket 11 is connected with a shaft sleeve 12. The shaft 22 of the rib plate 20 can be passed through and placed on the shaft sleeve 12, and the main body of the rib plate 20 is close to the bracket 11. After the rib plate 20 is placed in place, it is in an upright state, so that each rib tube 30 can be easily installed.

[0029] The disassembly and assembly process of the rib-piercing tube 30 of this embodiment is as follows:

[0030] When installing the rib-penetrating tube 30, the limiting protrusion 31 of the rib-penetrating tube 30 is aligned with the giving way groove 210 on the rib-penetrating plate 20, and then the rib-penetrating tube 30 is pushed inward. After the limiting protrusion 31 of the rib-penetrating tube 30 passes through the giving way groove 210 of the rib-penetrating plate 20 and rotates a certain angle (such as 90°), the limiting protrusion 31 on the rib-penetrating tube 30 abuts against the side of the rib-penetrating plate 20 away from the axial limiting protrusion 32. At the same time, the spring 40 is also compressed and abuts against the side of the rib-penetrating plate 20 facing the axial limiting protrusion 32. At this point, the rib-penetrating tube 30 can be fixed relative to the rib-penetrating plate 20 under the elastic force of the spring 40, that is, it is in a locked state. When the rib-penetrating tube 30 needs to be disassembled, the rib-penetrating tube 30 is rotated to a position where the limiting protrusion 31 and the clearance groove 210 are opposite in the axial direction. Under the elastic force of the spring 40, the limiting protrusion 31 can automatically move into or even withdraw from the clearance groove 210 (at this time, it is in an unlocked state), and then the rib-penetrating tube 30 can be pulled out. This disassembly and assembly structure of the rib-penetrating tube 30 is easy to operate and simplifies the disassembly and assembly process of the rib-penetrating tube 30, so that the disassembly and assembly of a single rib-penetrating tube 30 can be shortened to about 20 seconds, effectively solving the problem of long disassembly and assembly time and difficulty in disassembly and assembly of the rib-penetrating tube 30.
