Description

Technical Field

[0001] The invention relates to a support arm, in particular to a support arm for a track machine. Background Art

[0002] In recent years, agricultural transport machinery has gradually become popular. However, due to the large number of mountainous areas in my country, there are still many places that cannot be reached by tractors. The transportation efficiency of mountain crops, including fruits and vegetables, is still low, and large-scale planting cannot be formed.

[0003] Therefore, rail transporters have appeared on the market. They lay tracks on the mountains, which can start and stop the transporters at any time to load and transport agricultural products. Since the tracks need to be laid on uneven and steep mountains, it is necessary to ensure the safety of the tracks after laying. The laying support of the tracks depends entirely on the support frame. The existing support frame is not strong enough as a whole, which makes the rail transporters have certain safety hazards. Some existing solutions cannot be well implemented due to the influence of factors such as mountains. Therefore, how to design a support frame with high strength, easy installation and safety has become a technical problem that needs to be solved urgently in the industry. Summary of the invention

[0004] The present invention aims to solve the existing technical problem by providing a support arm for a track machine, which has a simple structure and is easy to install, and can provide better track support for the track machine, thereby greatly improving the safety factor.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] The present invention discloses a support arm for a rail machine, which is installed on a bracket and includes a support body and a connector. The support body is provided with at least two vertical mounting holes, and the corresponding two side walls of the support body are recessed inward to form arc recesses, and the arc recess is located in the middle of the center connection of the two vertical mounting holes; the connector is provided with at least one horizontal mounting hole, and the horizontal mounting hole is matched on the mounting seat.

[0007] Compared with the prior art, the support arm for the track machine of the present invention has multiple vertical mounting holes and multiple horizontal mounting holes, wherein the vertical mounting holes are connected to the columns of the bracket, and the horizontal mounting holes are connected to the tracks of the track machine. The multiple designs can reduce the load of a single bracket, thereby improving the overall support strength; the arc concave structure saves materials and production costs, and also facilitates the placement during installation. In mountainous environments, more plants can be avoided, and installation is more convenient. Moreover, the arc concave can also lean against the branches of the plants to make it more stable; the two arc concave symmetrical left and right form two positive and negative stresses, which makes the anti-sway ability of the entire support arm stronger.

[0008] The connector is in the shape of a long octagon.

[0009] The design of the long octagon can greatly improve the support strength of the four sides of the connecting body.

[0010] There is one horizontal mounting hole. The connecting body is a single-sided ear, and the mounting seat is arranged on the side of the connecting body. There is a second connecting plate between the mounting seat and the connecting body.

[0011] The second connecting plate is a right-angled triangular rib plate. One right-angled side is connected to the side wall of the mounting seat, and the other right-angled side is fixed to the connecting body. And the height of the right-angled side of the rib plate connected to the side wall of the mounting seat is less than the height of the mounting seat.

[0012] For the support arm with only one horizontal mounting hole, it is more flexible during installation and can avoid obstacles in a small space.

[0013] There are two horizontal mounting holes, which are installed on two symmetrical mounting seats. There is a first connecting plate between the two mounting seats.

[0014] The first connecting plate includes a left rib plate and a right rib plate, and an angle is formed between the left rib plate and the right rib plate.

[0015] The angle is an obtuse angle.

[0016] Compared with the prior art, the installation strength between two adjacent mounting seats is greatly improved. Moreover, the left rib plate and the right rib plate are arranged in a scissor layout, and the angle between them is an obtuse angle. This makes the lines starting from the angle between the left rib plate and the right rib plate extend to the surfaces of the mounting seats along the left rib plate and the right rib plate respectively to the left and right, thus playing a supporting role for the mounting seats.

[0017] In addition, the left rib plate and the right rib plate in the scissor layout, while strengthening the strength of the mounting seat and the connecting body, also leave a certain space for avoidance, which is convenient for later installation by workers. Some anti-seismic materials can also be filled in this space to reduce the damage to the support arm caused by the vibration of the track during the operation of the track machine.

[0018] The left rib plate and the right rib plate are symmetrically arranged, and the heights of the ends of the left rib plate and the right rib plate connected to the corresponding mounting seats are less than the height of the mounting seat.

[0019] The obtuse angle extends into the end face of the connecting body.

[0020] The apex line of the obtuse angle extends and is embedded into the end face of the connecting body. That is to say, the apex line of the obtuse angle is below the end face of the connecting body. In this way, the part of the obtuse angle in the end face of the connecting body can obtain the support strength of the connecting body, which makes the support of the line to the surface more firm.

[0021] The starting end of the mounting seat is one end of the connecting surface between the connecting body and the support body, and the terminating end extends outside the connecting body.

[0022] The support body is provided with a set screw hole that penetrates through to the vertical mounting hole.

[0023] The beneficial effects of the present invention are as follows:

[0024] Compared with the prior art, by using the support arm for a track machine of the present invention, through the provision of a plurality of vertical mounting holes and one or more horizontal mounting holes, the connection between the support arm and the bracket and the track is made more firm and safe. Moreover, the design of the connecting plate and the arc recess further strengthens the overall strength of the support arm and improves safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0034] Embodiment 1

[0035] Please refer to Figures 1 to 4, the present invention provides a support arm for a track machine, which is integrally cast and formed, and includes a support body 101 and a connecting body 102. At least two vertical mounting holes 103 are provided on the support body 101, and the corresponding two side walls of the support body 101 are recessed inward to form arc recesses 104 respectively, and the arc recesses 104 are located in the middle of the connection between the centers of the two vertical mounting holes 103; a horizontal mounting hole 105 is provided on the connecting body 102, and the horizontal mounting hole 105 is matched on the mounting seat 106.

[0036] The support arm of the present invention is mounted on the bracket 107. The bracket 107 includes a support 108 and a column 109. The vertical mounting hole 103 of the support arm is sleeved on the column 109, while the support 108 is fixed on the ground; the fixation between the column 109 and the support arm is achieved by providing a set screw hole 110 on the support body 101 that penetrates through to the vertical mounting hole 103 and screwing a bolt into the set screw hole 110 so that the bolt abuts against the surface of the column 109 to achieve the purpose of fixation.

[0037] The connecting body 102 is in the shape of a long octagon.

[0038] The design of the long octagon can greatly improve the support strength of the four sides of the connecting body 102.

[0039] There is one horizontal mounting hole 105. The connecting body 102 is a single-sided ear, and the mounting seat is arranged on the side of the connecting body 102. There is a connecting plate two 111 between the mounting seat 106 and the connecting body 102.

[0040] The connecting plate two 111 is a right-angled triangular rib plate 112. One right-angled side is connected to the side wall of the mounting seat 106, and the other right-angled side is fixed to the connecting body 102, and the height of the right-angled side of the rib plate 112 connected to the side wall of the mounting seat 106 is less than the height of the mounting seat 106.

[0041] The support arm with only one horizontal mounting hole 105 is more flexible during installation and can avoid obstacles in a small space.

[0042] In summary, the support arm for the track machine in this embodiment has multiple vertical mounting holes 103 and one horizontal mounting hole 105. The vertical mounting holes 103 are docked with the column 109 of the bracket 107, and the horizontal mounting hole 105 is connected to the track of the track machine. The design of multiple vertical mounting holes 103 can reduce the load on a single bracket 107, thereby improving the overall support strength; the structure of the arc recess 104 saves materials and production costs while facilitating the picking and placing during installation. In a mountain environment, it can avoid more plants and is more convenient for installation. Moreover, the arc recess 104 can also lean on the branches of plants to make it more stable; the two arc recesses 104 that are symmetric about the left and right form two mutually positive and negative stresses, making the anti-shaking ability of the entire support arm stronger.

[0043] Example Two

[0044] Please refer to Figures 5 to 8 , the present invention provides a support arm for a rail machine, which is integrally cast and formed, including a support body 201 and a connecting body 202. At least two vertical mounting holes 203 are provided on the support body 201, and arc recesses 204 are respectively formed by inward depressions on the corresponding two side walls of the support body 201, and the arc recesses 204 are in the middle of the central connection of the two vertical mounting holes 203; two horizontal mounting holes 205 are provided on the connecting body 202, and the two horizontal mounting holes 205 are symmetrically matched on the mounting seat 206, and there is a connecting plate one 207 between adjacent two mounting seats 206.

[0045] The support arm of the present invention is installed on the bracket 208. The bracket 208 includes a support 209 and a column 210. The vertical mounting hole 203 of the support arm is sleeved on the column 210, and the support 209 is fixed on the ground; the fixation between the column 210 and the support arm is achieved by providing a set screw hole 211 on the support body that penetrates to the vertical mounting hole 203, and screwing a bolt into the set screw hole 211 so that the bolt abuts against the surface of the column 210 to achieve the purpose of fixation.

[0046] Moreover, there are multiple vertical mounting holes 203 and horizontal mounting holes 205 in the present invention, which further improves the installation firmness.

[0047] For the support arm of the rail machine of the present invention, the structure of the arc recess 204 saves materials and production costs, and at the same time, it is convenient for picking and placing during installation. In the mountain environment, it can avoid more plants and is more convenient for installation. Moreover, the arc recess 204 can also lean on the branches of plants to make it more stable; the two arc recesses 204 that are symmetric left and right form two mutually positive and negative stresses, making the anti-shake ability of the entire support arm stronger.

[0048] The connecting body 202 is in the shape of a long octagon. The specific structure of this long octagon is: chamfers 212 are designed at the four corners of the rectangular connecting body 202 to achieve the shape of a long octagon.

[0049] The design of the long octagon can greatly improve the support strength of the four sides of the connecting body 202. Moreover, the cross-section of the mounting seat 206 is circular, and the straight line of the chamfer 212 is the outer tangent of the circle.

[0050] The connecting plate one 207 includes a left rib plate 213 and a right rib plate 214, and an included angle α is formed between the left rib plate 213 and the right rib plate 214.

[0051] Preferably, the included angle α is an obtuse angle.

[0052] On the one hand, with the connecting plate 207, the installation strength between two adjacent mounting seats 206 is greatly improved; on the other hand, the left rib plate 213 and the right rib plate 214 are arranged in a scissor pattern, and the included angle α between them is an obtuse angle. This makes the lines starting from the included angle α between the left rib plate 213 and the right rib plate 214 extend left and right along the left rib plate 213 and the right rib plate 214 to the surface of the mounting seat 206 respectively, thus playing a supporting role for the mounting seat 206.

[0053] As we know, when using scissors to cut objects with a smaller outer diameter, only a relatively small force is required to cut them. When cutting objects with a larger outer diameter, a larger force is needed to cut them. Therefore, when the included angle α between the left rib plate 213 and the right rib plate 214 of the present invention is an obtuse angle, the supporting force obtained by the two mounting seats 206 is relatively large.

[0054] In addition, the left rib plate 213 and the right rib plate 214 arranged in a scissor pattern, while strengthening the strength of the mounting seat 206 and the connecting body 202, also leave a certain space for later installation by workers. Some anti-seismic materials can also be filled in this space to reduce the damage to the support arm caused by the vibration of the track during the operation of the track machine.

[0055] The left rib plate 213 and the right rib plate 214 are symmetrically arranged, and the height of the ends of the left rib plate 213 and the right rib plate 214 connected to the corresponding mounting seat 206 is less than the height of the mounting seat 206. Such a design, on the one hand, leaves enough space between two adjacent mounting seats 206; on the other hand, it also effectively improves the connection strength between two adjacent mounting seats 206. On the other hand, the height of the ends of the left rib plate 213 and the right rib plate 214 connected to the corresponding mounting seat 206 being less than the height of the mounting seat 206 is more for increasing the angle of the obtuse angle, but the angle cannot be too large, such as 180 degrees, that is, the left rib plate 213 and the right rib plate 214 merge into one as a whole, then the purpose of the scissor design of the present invention is lost.

[0056] The obtuse angle extends into the end face 215 of the connecting body 202.

[0057] The vertex line 216 of the obtuse angle extends and is embedded in the end face 215 of the connecting body 202. That is to say, the vertex line 216 of the obtuse angle is below the end face 215 of the connecting body 202. In this way, the part of the obtuse angle within the end face 215 of the connecting body 202 can obtain the supporting strength of the connecting body 202, making the support of the line to the plane more firm.

[0058] The starting end of the mounting seat 206 is one end of the connecting surface between the connecting body 202 and the support body 201, and the terminating end extends beyond the connecting body 202.

[0059] The support arm for the rail machine of the present invention is designed such that the horizontal mounting hole 205 and the vertical mounting hole 203 are perpendicular to each other. The bolt passes through the horizontal mounting hole 205 and is screwed to the side of the rail, thereby playing a supporting role for the rail. At this time, the rail has a downward acting force on the support arm, and the direction of this acting force is downward with the connection between the column 210 and the vertical mounting hole 203 as the fulcrum. The designs of at least two vertical mounting holes 203, at least two horizontal mounting holes 205, and the first connecting plate 207 are all for resisting this acting force and the vibration force generated during the operation of the rail machine, so that the support of the support arm for the rail becomes safer, more stable, and firmer.

[0060] The above has introduced in detail the support arm for the rail machine provided by the embodiments of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the technical solution disclosed by the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation of the present invention.
