Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe hard beam arching, and particularly relates to a hard beam arching assembly tool. BACKGROUND

[0002] The steel pipe hard beam is a kind of hard cross span, which has the advantages of mechanical independence, no influence between tracks, small accident range, stable structure, good anti-vibration and anti-wind performance, and strong stability. Moreover, the hard cross span has good rigidity, high stability, and can improve the pantograph current collection, thereby having a series of advantages such as small abrasion and reduced off-line rate.

[0003] The span of the steel pipe hard beam is generally between 10m and 40m. In order to overcome the deflection caused by the self-weight of the beam and the upper load, the hard beam needs to be arched by 1 / 1000-3 / 1000 (arched line segment according to R200M) during production.

[0004] In the related prior art, two main rod steel pipes with the lowest point are fixed on a flat steel plate, and each main rod steel pipe is clamped by a spring clamp. An abdominal rod steel pipe is placed between the two main rod steel pipes, and pre-assembly is performed by electric welding. After single-piece inclined standing, the whole is assembled.

[0005] In the above prior art, the angle of the abdominal rod steel pipe connecting the main rod steel pipe with the highest point and the two main rod steel pipes with the lowest point after single-piece inclined standing is difficult to control, and the angle of the abdominal rod steel pipe along the line is often uneven. As a result, misalignment is easily formed when welding the main rod steel pipe with the highest point, which cannot guarantee the effect of good pre-stress of the arch frame and increases the labor intensity. SUMMARY

[0006] Based on the above description, the present application provides a hard beam arching assembly tool, which aims to solve the problem that the angle of the abdominal rod steel pipe along the line is difficult to balance after single-piece inclined standing during the arching assembly of the existing hard beam, and misalignment is easily formed when welding the main rod steel pipe with the highest point.

[0007] The technical solution of the present application to solve the above technical problems is as follows:

[0015] Further, the limiting rod and the bottom support are provided with a bolt for strengthening the damping effect of the main rod steel pipe.

[0016] Further, the bottom support comprises at least one base and a clamp arranged on the base; wherein the clamp is configured to limit the movement of the main rod steel pipe at the highest point.

[0017] Further, the clamp comprises a base plate, a bearing seat mounted on the base plate, two clamping assemblies arranged in mirror image along the bearing seat, at least one driving assembly for driving the two clamping assemblies to open and close, and a bearing plate arranged symmetrically along the bearing seat and used for bearing the two clamping assemblies; wherein the base has a through hole through which the at least one driving assembly passes, and the clamping assembly comprises a synchronization rod arranged in parallel with the bearing seat and a clamping jaw sleeved on both ends of the synchronization rod.

[0038] Example 1

[0039] See attached document Figures 1-4 As shown, the present invention provides a technical solution: a rigid crossbeam arching assembly fixture, including a base support 10, multiple support plates 20 and multiple limiting plates 30, the multiple support plates 20 being spaced apart on the base support 10 along a first direction; the multiple limiting plates 30 being arranged on each support plate 20 in a triangular arrangement of three limiting plates 30 each; wherein, each limiting plate 30 is constructed to have a slot extending away from the base support 10 and forming an opening, the bottom wall of the slot being adapted to the diameter of the main steel pipe.

[0040] It can be understood that each limiting plate 30 can be detachably connected to the support plate 20 by means of bolts or the like; or the limiting plate 30 at the highest point can be integrally formed on the support plate 20 away from the bottom support 10, and the two limiting plates 30 at the lowest point can be detachably connected to the support plate 20 by means of bolts or the like.

[0041] According to this embodiment, main steel pipes are placed in the slots of each limiting plate 30 arranged along the first direction to form a triangular arrangement; and intermittently welded web steel pipes are formed between every two adjacent main steel pipes to form an arch frame. Compared with the traditional method, this application has a simple structure and facilitates tooling disassembly and transportation. The arch frame can achieve the purpose of one-time assembly and can meet the arch requirements of various lengths of rigid crossbeams, improving production efficiency.

[0042] See attached document Figures 1-2 As shown, in some embodiments, the base 10 includes at least two support members 11 arranged parallel to each other and a connecting member 12 located on the at least two support members 11 and spaced apart along a first direction.

[0043] This can be understood as follows: the supporting component 11 can be a plate structure, or it can be an I-beam or H-beam, etc. The connecting component 12 can be a block structure, or it can be a square steel, etc. The connecting component 12 is selected for detachable connection by bolts or welding, depending on the material of the supporting component 11. The aforementioned methods are all existing technologies, so they will not be described in detail here.

[0044] According to this embodiment, this configuration not only ensures that the base support 10 has a strong load-bearing capacity, but also ensures the advantages of simple construction, low material cost and easy material selection.

[0045] Refer to the attached Figures 1-2 As shown, in some embodiments, the support plate 20 forms a trapezoidal structure, and has an adaptation concave surface 21 coaxial with the card slot on the first inclined surface 20a and the second inclined surface 20b of the support plate 20.

[0046] According to this embodiment, the adaptation concave surface 21 can avoid the blocking of the first inclined surface 20a and the second inclined surface 20b on the main pipe steel and increase the damping effect, which is beneficial to facilitate the insertion or removal.

[0047] Refer to the attached Figure 1 and 3 As shown in FIGS. 1 to 4, in some embodiments, on the side of each support plate 20 away from the limiting plate 30, there are at least two clamping plates 40 arranged parallel to each other in the vertical direction and a limiting rod 50 placed horizontally; among them, the combination of at least two clamping plates 40 and the limiting rod 50 is configured to be able to limit the positions of the two main pipe steels at the lowest point.

[0048] It can be understood that the clamping plate 40 can be ┐-shaped, -shaped or 冂-shaped, etc., and preferably -shaped and 冂-shaped.

[0049] According to this embodiment, after the two main pipe steels at the lowest point are placed, by using the combination of the clamping plate 40 and the limiting rod 50, it can prevent the two main pipe steels at the lowest point from moving during welding, which causes inconvenience in welding.

[0050] Refer to the attached Figure 1 and 3 As shown in FIGS. 1 to 4, in some embodiments, there is a pin 60 between the limiting rod 50 and the bottom support 10, which has a strengthening damping effect on the main pipe steel.

[0051] According to this embodiment, when the diameter of the main pipe steel is slightly small, the pin 60 can be combined with the clamping plate 40 and the limiting rod 50 to further block the main pipe steel, making the main pipe steel more紧固 with the clamping plate 40.

[0052] Embodiment 2

[0053] Refer to the attached Figure 1 and 5 As shown in FIGS. 1 to 7, in order to prevent the main pipe steel at the highest point from accidentally moving during welding, which may cause the misalignment of the main pipe steel or be unfavorable for the welding operation. Based on the technical solution of Embodiment 1, this application further includes at least one base 7⃣0 provided on the bottom support 10 and a fixture 8⃣0 located on at least one base 7⃣0; among them, the fixture 8⃣0 is configured to be able to limit the movement of the main pipe steel at the highest point.

[0054] It can be understood that the number of bases 7⃣0 can be one, two or three, etc., increasing in sequence, and the number of fixtures 8⃣0 is determined according to the total amount of bases 7⃣0.

[0055] According to this embodiment, during the welding operation, the main steel pipe at the highest point is clamped by the clamp 80, which can prevent the main steel pipe from moving. This is beneficial for keeping the positions of the three main steel pipes consistent and also facilitates the welding operation.

[0056] See attached document Figure 1 and 5 As shown in Figures 6-6, in some embodiments, the clamp 80 includes a base plate 81, a support 82 mounted on the base plate 81, two clamping assemblies 83 arranged mirror-imagely along the support 82, at least one drive assembly 84 for driving the opening and closing of the two clamping assemblies 83, and a support plate 86 symmetrically arranged along the support 82 for supporting the two clamping assemblies 83; wherein, the base 70 has a through hole 811 through which at least one drive assembly 84 can pass, and the clamping assembly 83 includes a synchronizing rod 831 arranged parallel to the support 82 and grippers 832 sleeved at both ends of the synchronizing rod 831. In this embodiment, the drive assembly 84 includes a cam 841 sleeved at one end of the synchronizing rod 831 and a linear drive mechanism 842 whose output end is rotatably connected to the cam 841.

[0057] This can be understood as the fact that there can be two drive components 84, with each clamping component 83 connected to one drive component 84.

[0058] According to this embodiment, after the main steel pipe at the highest point is placed, the linear drive mechanism 842 drives the two synchronous rods 831 to make the two sets of grippers 832 (two grippers 832 on each synchronous rod 831 constitute a set) move towards each other to clamp the main steel pipe at the highest point and prevent the main steel pipe at the highest point from moving.

[0059] See attached document Figure 1 and 5 As shown in Figure 6, in some embodiments, each clamping plate 872 is provided with a groove 8321. This can further prevent the main steel pipe at the highest point from moving.

[0060] See attached document Figure 1 and 5 As shown in Figures 6-6, in some embodiments, anti-slip protrusions 8322 are provided within each groove 8321. This can further prevent the main steel pipe at the highest point from moving horizontally.

[0061] See attached document Figure 1 and 5 As shown in Figure 7, in another embodiment, the clamp 80 includes a transmission assembly 85, which includes a first gear 851 and a second gear 852 that mesh with each other, and the first gear 851 and the second gear 852 are each sleeved on a synchronizing rod 831.

[0062] It can be understood that the driving component 84 can be a single component, and a clamping component 83 is connected to the driving component 84.

[0063] According to this embodiment, the linear drive mechanism 842 drives one of its synchronizing rods 831 to rotate. Under the action of the first gear 851 and the second gear 852, the other synchronizing rod 831 follows the rotation, so that the two sets of grippers 832 (two grippers 832 on each synchronizing rod 831 form a set) move towards each other to clamp the main steel pipe at the highest point and prevent the main steel pipe at the highest point from moving.

[0064] See attached document Figure 1 and 5 As shown in ~7, in some embodiments, the clamp 80 includes a fastening assembly 87, which includes two side plates 871 detachably connected to the base 70 and parallel to each other, two clamping plates 872 disposed opposite to each other and capable of accommodating the linear drive mechanism 842, and a double-ended lead screw 873 for adjusting the spacing between the clamping plates 872; wherein each clamping plate 872 is connected to one side plate 871.

[0065] According to this embodiment, by using the adjustable pitch of the double-ended lead screw 873, the linear drive mechanism 842 can be tightened more securely, preventing the linear drive mechanism 842 from falling off.

[0066] See attached document Figure 1 and 5 As shown in Figure 7, in some embodiments, the clamp 80 includes a base 88 for detachably connecting the clamp 80 to the base 70. The base 88 includes a plurality of uprights 881 distributed circumferentially, a first base plate 882 detachably connected to the plurality of uprights 881, and a second base plate 883 detachably connected to the first base plate 882; wherein the plurality of uprights 881 are detachably connected to the base plate 81.

[0067] According to this embodiment, the arrangement of multiple uprights 881 creates a certain distance between the substrate 81 and the base 70, and also creates a certain distance between the linear drive mechanism 842 and the base 70, which is beneficial for the maintenance of the linear drive mechanism 842.

[0068] See attached document Figure 8 As shown, the specific implementation steps of this rigid crossbeam camber assembly fixture are as follows:

[0069] Step 1: Place the three main steel pipes into the slots of the limiting plates 30 arranged along the first direction to form a triangular arrangement.

[0070] Step 2: Two drive components 84 or one drive component 84 and transmission component 85 work together to drive two clamping components 83 to move towards each other to clamp the main steel pipe at the highest point; at the same time, a limiting rod 50 is placed between the two main steel pipes at the lowest point and the clamping plate 40, and a pin 60 is placed between the two main steel pipes at the lowest point and the base support 10.

[0071] Step 3: Weld web steel pipes at intervals along the first direction between every two adjacent main steel pipes to form an arch frame.

[0072] It should be noted that the linear drive mechanism 842 is a linear motor, pneumatic cylinder, or hydraulic cylinder, etc. The model and specifications of the linear motor, pneumatic cylinder, or hydraulic cylinder, etc., need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0073] The power supply and operating principles of linear motors, cylinders, or hydraulic cylinders are clear to those skilled in the art and will not be described in detail here.

[0074] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
