[0001] The present application relates to the technical field of track iron teeth installation, and in particular to an anti-falling track iron teeth. Background Art

[0002] In the endless belt type rubber crawler formed of rubber elastic body, steel wires are buried as a reinforcing skeleton in the circumferential direction, and iron teeth are buried at a certain interval to enhance the gripping power of the rubber crawler.

[0003] The utility model patent with announcement number CN201729201U proposes the present: an iron tooth for a rubber track, comprising a bridge, a left wing portion and a right wing portion are fixedly arranged on both sides of the bridge, a left guide protrusion protruding from the front face of the bridge is fixedly connected between the bridge and the left wing portion, a right guide protrusion protruding from the front face of the bridge is fixedly connected between the bridge and the right wing portion, two positioning teeth that are staggered and cooperate with each other are respectively arranged at both ends of the outer end of the left wing portion in the width direction, two positioning teeth that are staggered and cooperate with each other are respectively arranged at both ends of the outer end of the right wing portion in the width direction, and a clamping portion that can be clamped up and down is respectively arranged at the end of one of the two positioning teeth located on the same side and the side of the root of the other positioning tooth.

[0004] The above-mentioned track iron teeth are meshed with each other through corresponding positioning teeth, so that adjacent iron teeth can be engaged with each other up and down, left and right, thereby improving the stability of the iron tooth installation. When a single iron tooth is damaged due to friction, multiple iron teeth need to be disassembled before the damaged iron tooth can be replaced, which makes the replacement of the iron teeth very inconvenient. Utility Model Content

[0005] The purpose of the utility model is to solve or at least alleviate the problem that after the existing iron teeth are installed, they are fixed together by positioning teeth. When a single iron tooth is damaged due to friction, it is necessary to disassemble multiple iron teeth before the damaged iron tooth can be replaced, which makes the replacement of the iron teeth very inconvenient.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The anti-falling track iron tooth comprises an iron tooth body arranged on one side of the track body, a clamping structure is arranged in the iron tooth body, and also comprises a connecting piece arranged on the other side of the track body and penetrating the track body, the clamping structure comprises a clamping hole with a trapezoidal cross-section opened inside the iron tooth body, an extrusion rod is fixedly connected to the bottom wall of the inner cavity of the clamping hole, the connecting piece comprises a connecting rod with one end penetrating the track body, a limiting disk is welded to the end of the connecting rod away from the iron tooth body, and a plug with a circular tubular structure is fixedly connected to the end of the connecting rod close to the iron tooth body, and a plurality of expansion grooves are symmetrically opened on the side wall around the plug.

[0008] By adopting the above technical solution, when using, the user first inserts the cannula through the through hole provided on the crawler body, and then inserts a section of the cannula with the expansion groove into the clamping hole provided on the iron tooth body. Since the cannula is a round tube structure, and the top of the extrusion rod is opposite to the inner cavity of the cannula, when the cannula is inserted into the clamping hole, the extrusion rod is inserted into the inner cavity of the cannula from the bottom end of the cannula in the opposite direction. As the insertion depth of the extrusion rod increases, the diameter of the contact part between the extrusion rod and the bottom end of the cannula gradually increases, which will squeeze the inner wall of the cannula toward the circumference, so that the inner wall of the cannula is expanded along the expansion groove. The expansion groove opens until the bottom end of the insert is squeezed to fit with the bottom wall of the snap-in hole. At this time, the expanded and deformed insert can stably fix the iron tooth body on the track body through the connecting rod. Since each iron tooth body is independent of each other, when a single or part of the iron tooth body is damaged, it is only necessary to dismantle the damaged iron tooth body and replace it, thereby avoiding as much as possible the problem that the existing iron teeth are fixed to each other by the positioning teeth after installation. When a single iron tooth is damaged due to friction, it is necessary to dismantle multiple iron teeth before replacing the damaged iron tooth, which makes the replacement of the iron teeth very inconvenient.

[0009] Optionally, a plurality of horizontally arranged transverse steel wires and a plurality of longitudinal steel wires perpendicular to the transverse steel wires are embedded in the crawler body, and the transverse steel wires and the longitudinal steel wires are welded to each other at their intersections to form a mesh structure.

[0010] By adopting the above technical solution, a metal mesh formed by cross-welding multiple transverse steel wires and longitudinal steel wires is embedded inside the track body to reinforce the track body, improve the tensile strength of the track body, and increase the service life of the track body.

[0011] Optionally, a plurality of equidistantly distributed through holes are provided on the crawler body, the inner diameter of the through holes is equal to the diameter of the connecting rod, and the diameter of the limiting plate is larger than the inner diameter of the through holes.

[0012] By adopting the above technical solution, a through hole is set so that one end of the connecting rod fixedly connected with the insert can pass through the through hole to penetrate the track body and be inserted into the inside of the iron tooth body, so that the upper surface of the iron tooth body cooperates with the limit plate welded on the top of the connecting rod to clamp and fix the iron tooth body on the track body, thereby realizing stable installation of the iron tooth body.

[0013] Optionally, a top section of the iron tooth body is a rectangular columnar structure, a bottom section of the iron tooth body is a prism-shaped structure, and a cross-sectional area of ​​the bottom end of the iron tooth body is smaller than a cross-sectional area of ​​the top end of the iron tooth body.

[0014] By adopting the above technical solution, the cross-sectional area of ​​the bottom end of the iron tooth body is set to be smaller than the cross-sectional area of ​​the top end of the iron tooth body, so as to increase the pressure between the bottom end of the iron tooth body and the ground, thereby greatly improving the grip of the iron tooth body.

[0015] Optionally, the extrusion rod is in a truncated cone structure, and the distance between the circumference of the extrusion rod and the inner wall of the clamping hole is equal to the thickness of the side wall of the insertion tube.

[0016] By adopting the above technical solution, the extrusion rod is set to a truncated cone structure, so that the distance between the circumference of the extrusion rod and the inner wall of the clamping hole is the same, which is convenient for fixing the inner wall of the cannula after expansion and deformation.

[0017] Optionally, a reinforcing ring with an annular structure is sleeved on one end of the insert tube away from the connecting rod. The reinforcing ring is slidably connected to the insert tube, and the length of the reinforcing ring is equal to the distance between the top wall of the expansion groove and the connecting rod.

[0018] By adopting the above technical solution, a reinforcement ring is provided to be sleeved on the end of the insert tube when not in use, so as to prevent the insert tube from being deformed along the expansion groove after being squeezed by external force. When the end of the insert tube is inserted into the inner cavity of the clamping hole, the reinforcement ring is pushed by the side wall of the open end of the clamping hole to slide toward the section where the insert tube is connected to the connecting rod, thereby reinforcing a section of the insert tube above the expansion groove, and minimizing the problem of the insert tube being cracked due to squeezing, which affects the stability of the installation of the iron tooth body.

[0019] Optionally, a receiving groove is provided on the upper surface of the iron tooth body, the inner cavity size of the receiving groove is adapted to the size of the reinforcement ring, and the top of the clamping hole is connected to the inner cavity of the receiving groove.

[0020] By adopting the above technical solution, a receiving groove is opened on the upper surface of the iron tooth body to accommodate a reinforcement ring for reinforcing the insert, so that the iron tooth body can fit closely with the lower surface of the crawler body after installation.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] The present application arranges the structures such as the snap-in hole, the extrusion rod, the connecting rod, the insert pipe and the expansion groove in coordination. During installation, the iron tooth body is placed under the track body, and then the end of the connecting rod fixed with the insert pipe passes through the track body and is snapped into the snap-in hole. The iron tooth body is stably installed on the track body through the limit plate and the connecting rod. Since the iron tooth bodies are independent of each other, when a single iron tooth body is damaged, only the damaged iron tooth body needs to be disassembled and replaced, which avoids the existing iron teeth from snapping into each other after installation. When a single iron tooth is damaged, multiple iron teeth need to be disassembled to replace the damaged iron tooth, which makes the replacement of the iron teeth very inconvenient.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] See also Figure 1-3 The anti-falling track iron tooth includes an iron tooth body 5 arranged on one side of the track body 1, a clamping structure is provided inside the iron tooth body 5, and also includes a connecting piece arranged on the other side of the track body 1 and penetrating the track body 1. The connecting piece penetrates the track body 1 and is inserted into the clamping structure provided inside the iron tooth body 5, so that the iron tooth body 5 is stably installed on the track body 1.

[0029] The clamping structure includes a clamping hole 7 with a trapezoidal cross-section opened inside the iron tooth body 5. An extrusion rod 8 is fixedly connected to the bottom wall of the inner cavity of the clamping hole 7. The extrusion rod 8 is a truncated cone structure, and the diameter of the extrusion rod 8 gradually decreases from the bottom to the top of the extrusion rod 8.

[0030] The connecting part includes a connecting rod 9 with one end passing through the track body 1. The length of the connecting rod 9 is equal to the thickness of the track body 1, so that the connecting rod 9 can be completely embedded in the track body 1. A limiting plate 10 is welded to the end of the connecting rod 9 away from the iron tooth body 5. The top end of the connecting rod 9 is limited by the limiting plate 10 to prevent the connecting rod 9 from slipping off from under the track body 1.

[0031] The end of the connecting rod 9 close to the iron tooth body 5 is fixedly connected with a plug 11 of a circular tubular structure, and a plurality of expansion grooves 12 are symmetrically provided on the side wall of the plug 11. When in use, the user first passes the plug 11 through the crawler body 1, and then inserts the plug 11 into the clamping hole 7 provided in the iron tooth body 5. Since the plug 11 is a circular tubular structure, and the top of the extrusion rod 8 is opposite to the inner cavity of the plug 11, when the plug 11 is inserted into the clamping hole 7, the extrusion rod 8 is reversely inserted from the bottom end of the plug 11 into the inner cavity of the plug 11. As the insertion depth of the extrusion rod 8 increases, the diameter of the part where the extrusion rod 8 fits with the bottom end of the plug 11 gradually increases, and the inner wall of the plug 11 is squeezed toward the circumference, so that the inner wall of the plug 11 is opened along the expansion groove 12, until the bottom end of the plug 11 is squeezed to fit with the bottom wall of the clamping hole 7. At this time, the expanded and deformed plug 11 can stably fix the iron tooth body 5 on the crawler body 1 through the connecting rod 9.

[0032] Reference Figure 1The track body 1 has a plurality of horizontally arranged transverse steel wires 2 and a plurality of longitudinal steel wires 3 perpendicular to the transverse steel wires 2 embedded therein, and the transverse steel wires 2 and the longitudinal steel wires 3 are welded to each other at their intersections to form a mesh structure. The metal mesh formed by the cross-welding of the plurality of transverse steel wires 2 and the longitudinal steel wires 3 embedded therein is used to reinforce the track body 1, improve the tensile resistance of the track body 1, and increase the service life of the track body 1.

[0033] Reference Figure 1 The crawler body 1 is provided with a plurality of equally spaced through holes 4, the inner diameter of the through holes 4 is equal to the diameter of the connecting rod 9, and the diameter of the limiting plate 10 is larger than the inner diameter of the through holes 4. The through holes 4 are provided so that one end of the connecting rod 9 fixedly connected with the insert 11 can pass through the crawler body 1 through the through holes 4 and be inserted into the inside of the iron tooth body 5, so that the upper surface of the iron tooth body 5 cooperates with the limiting plate 10 welded on the top of the connecting rod 9 to clamp and fix the iron tooth body 5 on the crawler body 1, thereby realizing the stable installation of the iron tooth body 5.

[0034] Reference Figure 1 and Figure 3 The top section of the iron tooth body 5 is a rectangular columnar structure, the bottom section of the iron tooth body 5 is a prism-shaped structure, and the cross-sectional area of ​​the bottom end of the iron tooth body 5 is smaller than the cross-sectional area of ​​the top end of the iron tooth body 5. The cross-sectional area of ​​the bottom end of the iron tooth body 5 is set to be smaller than the cross-sectional area of ​​the top end of the iron tooth body 5, which is used to increase the pressure between the bottom end of the iron tooth body 5 and the ground, and greatly improves the grip of the iron tooth body 5.

[0035] Reference Figure 1 The extrusion rod 8 is in a truncated cone structure, and the distance between the circumference of the extrusion rod 8 and the inner wall of the clamping hole 7 is equal to the thickness of the side wall of the insertion tube 11. The extrusion rod 8 is set to a truncated cone structure, so that the distance between the circumference of the extrusion rod 8 and the inner wall of the clamping hole 7 is the same, which is convenient for fixing the inner wall of the insertion tube 11 after expansion and deformation.

[0036] Reference Figure 2 A reinforcing ring 13 in an annular structure is sleeved on one end of the insert tube 11 away from the connecting rod 9. The reinforcing ring 13 is slidably connected to the insert tube 11, and the length of the reinforcing ring 13 is equal to the distance between the top wall of the expansion groove 12 and the connecting rod 9. The reinforcing ring 13 is set to be sleeved on the end of the insert tube 11 when not in use to prevent the insert tube 11 from deforming along the expansion groove 12 after being squeezed by external force. When the end of the insert tube 11 is inserted into the inner cavity of the clamping hole 7, the reinforcing ring 13 is pushed by the side wall of the open end of the clamping hole 7 to slide toward the section where the insert tube 11 is connected to the connecting rod 9, and the section of the insert tube 11 above the expansion groove 12 is reinforced, so as to avoid the insert tube 11 from cracking due to squeezing, which affects the stability of the installation of the iron tooth body 5.

[0037] Reference Figure 3The upper surface of the iron tooth body 5 is provided with a receiving groove 6, the inner cavity size of the receiving groove 6 is adapted to the size of the reinforcement ring 13, and the top of the clamping hole 7 is connected with the inner cavity of the receiving groove 6. The receiving groove 6 is provided on the upper surface of the iron tooth body 5 to accommodate the reinforcement ring 13 for reinforcing the insertion tube 11, so that the iron tooth body 5 can be closely fitted with the lower surface of the crawler body 1 after installation.

[0038] The implementation principle of the present application is as follows: when in use, the user first inserts the insert tube 11 through the through hole 4 provided on the crawler body 1, and then inserts a section of the insert tube 11 provided with the expansion groove 12 into the inside of the clamping hole 7 provided on the iron tooth body 5. Since the insert tube 11 is in a round tubular structure, and the top end of the extrusion rod 8 is relatively positioned with the inner cavity of the insert tube 11, when the insert tube 11 is inserted into the inside of the clamping hole 7, the extrusion rod 8 is reversely inserted from the bottom end of the insert tube 11 into the inner cavity of the insert tube 11. As the insertion depth of the extrusion rod 8 increases, the diameter of the part where the extrusion rod 8 fits with the bottom end of the insert tube 11 gradually increases, and the inner wall of the insert tube 11 will be squeezed toward the circumferential side. The inner wall of the insert tube 11 is opened along the expansion groove 12 until the bottom end of the insert tube 11 is squeezed to fit with the bottom wall of the clamping hole 7. At this time, the expanded and deformed insert tube 11 can stably fix the iron tooth body 5 on the track body 1 through the connecting rod 9. Since each iron tooth body 5 is independent of each other, when a single or part of the iron tooth body 5 is damaged, it is only necessary to disassemble the damaged iron tooth body 5 and replace it, which avoids the problem that the existing iron teeth are fixed to each other by positioning teeth after installation. When a single iron tooth is damaged due to friction, multiple iron teeth need to be disassembled before the damaged iron tooth can be replaced, which makes the replacement of the iron teeth very inconvenient.
