Description

Technical Field

[0001] This utility model relates to the technical field of bridge assembly equipment, and more specifically, to an anchoring mechanism and a climbing crane suitable for different upper chord widths. Background Technology

[0002] Climbing cranes, such as full-rotation climbing cranes, are mainly used for the installation of steel truss arch bridges.

[0003] Before hoisting the members of a steel truss arch bridge, the climbing crane needs to use a winch to first pull the front traveling mechanism wheel box of the climbing crane to the anchorage position of the upper chord of the steel truss arch bridge. Then, it is connected to the two anchoring lugs of the upper chord through two anchoring plates, so that the front traveling mechanism wheel box is converted from the traction traveling system of the winch to the anchoring system of the anchoring lugs. All the load of the front traveling mechanism wheel box is transferred to the anchoring lugs before the hoisting operation of the steel truss arch bridge members can be carried out.

[0004] However, since one end of the two anchor plates is connected to the left and right side walls of the wheel box of the front traveling mechanism, and the other end is connected to the corresponding anchor lug, the spacing between the two anchor plates is fixed. This means that the existing anchor plates can only be used for steel truss arch bridges with a single width of upper chord, and cannot meet the construction operations of steel truss arch bridges with two different widths of upper chord, resulting in poor versatility of the anchor plates. Utility Model Content

[0005] The problem this invention addresses is how to effectively improve the versatility of anchoring mechanisms.

[0006] To address the aforementioned problems, this utility model provides an anchoring mechanism suitable for different upper chord widths, comprising two first tie plate structures, two second tie plate structures, a strut structure, and two anchoring lugs. One end of each of the two first tie plate structures is connected to two opposite side walls of the wheel box of the front traveling mechanism. Each second tie plate structure includes a first bend and a second bend. The first bend is detachably connected to the other end of the first tie plate structure and one of the anchoring lugs, and the second bend is detachably connected to the other end of the first tie plate structure and the other anchoring lug. The first interval between the two first bends is greater than the second interval between the two second bends. The two anchoring lugs are used for installation on the upper chord of a steel truss arch bridge. Both ends of the strut structure are connected to the two anchoring lugs, and the length of the strut structure is adjustable.

[0007] Optionally, the second pull plate structure includes a second pull plate member, which includes a pull plate body, a first bent portion, and a second bent portion, wherein the first bent portion and the second bent portion are respectively located at both ends of the extension direction of the pull plate body;

[0008] The first bent portion of one second pull plate structure bends relative to the pull plate body toward another second pull plate structure, and the second bent portion of one second pull plate structure bends relative to the pull plate body toward a direction away from the other second pull plate structure.

[0009] Optionally, the second pull plate structure includes two second pull plate members spaced apart, the other end of the first pull plate structure is located between one end of the two second pull plate members and is connected by a first fastener; the anchoring ear plate is located between the other ends of the two second pull plate members and is connected by a second fastener.

[0010] Optionally, the second pull plate structure further includes a first spacer plate, which is disposed between the two pull plate bodies in the second pull plate structure.

[0011] Optionally, the second pull plate structure further includes a second spacer plate, with a second spacer plate disposed between the other end of the first pull plate structure and one end of the second pull plate member; and another second spacer plate disposed between the other end of the second pull plate member and the anchoring ear plate.

[0012] Optionally, the first pull plate structure has an adjustment hole at one end away from the front traveling mechanism wheel box, and the first fastener is used to adjust its position within the adjustment hole.

[0013] Optionally, the anchoring mechanism suitable for different upper chord widths includes two support rod structures, with the two ends of one support rod structure respectively connected to one end of the second pull plate member located between the two anchoring lugs, and the two ends of the other support rod structure respectively connected to the other ends of the two second pull plate members in the second pull plate structure.

[0014] Optionally, the strut structure includes two mounting seats, two hinge joints, and a telescopic rod. The two mounting seats are respectively mounted on the corresponding second pull plate members, and the two hinge joints are respectively rotatably connected to the corresponding mounting seats through rotating shafts. The two ends of the telescopic rod are respectively connected to the corresponding hinge joints, and the length of the telescopic rod is adjustable.

[0015] Optionally, the anchoring mechanism suitable for different upper chord widths further includes an anchoring box beam and a third fastener. The anchoring box beam is connected to the anchoring ear plate through the third fastener. The anchoring box beam is provided with a first pulley block, and the front traveling mechanism wheel box is provided with a second pulley block. The first pulley block and the second pulley block are used to connect the winch through a wire rope.

[0016] Secondly, this utility model provides a climbing crane, including a front traveling mechanism wheel box and an anchoring mechanism as described above, suitable for different upper chord widths.

[0017] The beneficial effects of this utility model on anchoring mechanisms applicable to different upper chord widths and on climbing cranes are:

[0018] An anchoring mechanism suitable for different upper chord widths includes at least two first tie plate structures, two second tie plate structures, a strut structure, and two anchoring lugs. The two anchoring lugs are pre-fixed, for example, welded to the upper part of the upper chord of the erected steel truss arch bridge, and the two anchoring lugs can serve as anchoring positions for the wheel boxes of the front traveling mechanism.

[0019] When the front traveling mechanism wheel box is moved along the traveling track by a winch to the anchorage position of the upper chord with a certain width (such as a small width), the front traveling mechanism wheel box can be fixed to the anchorage position of the upper chord in the following way: for example, one end of the two first tie plate structures is connected to the two opposite side walls of the front traveling mechanism wheel box, such as the left and right side walls. The two first bends of the two second tie plate structures can be connected to the other ends of the corresponding two first tie plate structures, and the two second bends of the two second tie plate structures can be connected to the corresponding two anchoring ear plates, so as to fix the front traveling mechanism wheel box to the anchorage position of the upper chord. For example, the tension of the wire rope between the winch and the front traveling mechanism wheel box can be adjusted to gradually transfer the load of the front traveling mechanism wheel box to the anchoring ear plates. Only when the load of the front traveling mechanism wheel box is completely transferred to the anchoring ear plates can the hoisting operation of the steel truss arch bridge be carried out. Because a strut structure is set between the two anchoring lugs, and the two ends of the strut structure are respectively connected to the corresponding anchoring lugs, the distance between the two anchoring lugs is supported and fixed to prevent the distance between the two anchoring lugs and the two second pull plate structures from changing during the transfer of the load on the front traveling mechanism wheel box, thereby ensuring the stability of the load on the front traveling mechanism wheel box on the upper chord.

[0020] However, when the front traveling mechanism wheel box of the climbing crane needs to operate on the upper part of the upper chord with a different width (e.g., a larger width), one end of the two first tie plate structures is connected to the two opposite side walls of the front traveling mechanism wheel box, such as the left and right side walls. The connection direction of the two second tie plate structures can be adjusted, for example, by connecting the two second bends of the two second tie plate structures to the other ends of the corresponding two first tie plate structures respectively, and connecting the two first bends of the two second tie plate structures to the corresponding two anchoring lugs respectively, so as to fix the front traveling mechanism wheel box to the anchoring position of the upper chord.

[0021] Because the two ends of the strut structure are respectively connected to two corresponding anchoring lugs, and the length of the strut structure is adjustable, the strut structure can be installed between the two anchoring lugs of the upper chord with a large width. In short, the anchoring mechanism can be applied to the construction of steel truss arch bridges with upper chords of two different widths, improving the versatility of the anchoring mechanism. This makes the operation of the anchoring mechanism simple during the hoisting of steel truss arch bridge segments with upper chords of different widths, which can greatly reduce operating costs and ensure safety performance.

[0038] In related technologies, climbing cranes, such as full-rotation climbing cranes, are mainly used for the installation of steel truss arch bridges.

[0039] Before hoisting the members of a steel truss arch bridge, the climbing crane needs to use a winch to first pull the front traveling mechanism wheel box of the climbing crane to the anchorage position of the upper chord of the steel truss arch bridge. Then, it is connected to the two anchoring lugs of the upper chord through two anchoring plates, so that the front traveling mechanism wheel box is converted from the traction traveling system of the winch to the anchoring system of the anchoring lugs. All the load of the front traveling mechanism wheel box is transferred to the anchoring lugs before the hoisting operation of the steel truss arch bridge members can be carried out.

[0040] However, since one end of the two anchor plates is connected to the left and right side walls of the wheel box of the front traveling mechanism, and the other end is connected to the corresponding anchor lug, the spacing between the two anchor plates is fixed. This means that the existing anchor plates can only be used for steel truss arch bridges with a single width of upper chord, and cannot meet the construction operations of steel truss arch bridges with two different widths of upper chord, resulting in poor versatility of the anchor plates.

[0041] To address the problems existing in the aforementioned related technologies, this embodiment provides an anchoring mechanism and a climbing crane applicable to different upper chord widths.

[0042] Combination Figure 1 As shown, this utility model embodiment provides an anchoring mechanism suitable for different widths of the upper chord 13, including two first pull plate structures 1, two second pull plate structures 2, a strut structure 3, and two anchoring lugs 4. One end of each of the two first pull plate structures 1 is used to connect to two opposite side walls of the wheel box 8 of the front traveling mechanism, respectively. The second pull plate structure 2 includes a first bend 211 and a second bend 212. The first bend 211 is detachably connected to the other end of the first pull plate structure 1 and one of the anchoring lugs 4, and the second bend 212 is detachably connected to the other end of the first pull plate structure 1 and the other of the anchoring lugs 4. The first interval between the two first bends 211 is greater than the second interval between the two second bends 212. The two anchoring lugs 4 are used to install on the upper chord 13 of the steel truss arch bridge. Both ends of the strut structure 3 are connected to the two anchoring lugs 4, and the length of the strut structure 3 is adjustable.

[0043] Specifically, the two anchoring lugs 4 can be pre-fixed to the upper part of the upper chord 13 of the steel truss arch bridge; for example, two can be along... Figure 1 The upper part of the upper chord 13 is welded and fixed at intervals along the X-axis in the coordinate system.

[0044] Both first tie plate structures 1 and two second tie plate structures 2 are along Figure 1 The X-axis direction in the coordinate system is set at intervals. Because the front traveling mechanism wheel box 8...Figure 1 The dimension in the X-axis direction of the coordinate system is smaller than the interval between the two anchoring lugs 4 (e.g., the width of the upper chord 13). The first pull plate structure 1 and the side wall of the front traveling mechanism wheel box 8 can be connected and fixed by a pin. Therefore, the end of the first pull plate structure 1 connected to the front traveling mechanism wheel box 8 can have a certain curvature relative to other parts of the first pull plate structure 1, so as to increase the connection area between the first pull plate structure 1 and the side wall of the front traveling mechanism wheel box 8, thereby improving the connection stability between the first pull plate structure 1 and the side wall of the front traveling mechanism wheel box 8.

[0045] The second pull plate structure 2 can serve as a connecting plate between the first pull plate structure 1 and the anchoring lug 4. The second pull plate structure 2 has a first bending portion 211 and a second bending portion 212, so the second pull plate structure 2 is an arc-shaped plate structure with arcs at both ends.

[0046] The length of the strut structure 3 is adjustable under the operation of the operator, so that the strut structure 3 can be used to assemble the two anchoring lugs 4 set on the upper part of the upper chord 13 of different widths.

[0047] In this embodiment, the anchoring mechanism applicable to different upper chord 13 widths includes at least two first tie plate structures 1, two second tie plate structures 2, a strut structure 3, and two anchoring lugs 4. The two anchoring lugs 4 are pre-fixed, for example, welded to the upper part of the upper chord 13 of the erected steel truss arch bridge, and the two anchoring lugs 4 can serve as the anchoring positions of the wheel box 8 of the front traveling mechanism.

[0048] When the front traveling mechanism wheel box 8 is pulled along the traveling track 12 by a winch to the anchoring position of the upper chord 13 with a certain width (e.g., a smaller width), the front traveling mechanism wheel box 8 can be fixed to the anchoring position of the upper chord 13 in the following way: for example, one end of the two first pull plate structures 1 is connected to the two opposite side walls of the front traveling mechanism wheel box 8, such as the left and right side walls, and the two first bends 211 of the two second pull plate structures 2 can be respectively connected to the other ends of the corresponding two first pull plate structures 1. The two second bends 212 of the two second tie plate structures 2 are respectively connected to the corresponding two anchoring lugs 4 to fix the front traveling mechanism wheel box 8 at the anchoring position of the upper chord 13. For example, the load of the front traveling mechanism wheel box 8 can be gradually transferred to the anchoring lugs 4 by adjusting the tension of the wire rope 10 between the winch and the front traveling mechanism wheel box 8. Only when the load of the front traveling mechanism wheel box 8 is completely transferred to the anchoring lugs 4 can the hoisting operation of the steel truss arch bridge be carried out. Since the strut structure 3 is set between the two anchoring lugs 4, and the two ends of the strut structure 3 are respectively connected to the corresponding anchoring lugs 4, the distance between the two anchoring lugs 4 is supported and fixed to prevent the distance between the two anchoring lugs 4 and the two second tie plate structures 2 from changing during the transfer of the load of the front traveling mechanism wheel box 8, thus ensuring the stability of the load of the front traveling mechanism wheel box 8 on the upper chord 13.

[0049] However, when the front traveling mechanism wheel box 8 of the climbing crane needs to operate on the upper part of the upper chord 13 with other widths, such as (larger width), one end of the two first pull plate structures 1 is connected to the two opposite side walls of the front traveling mechanism wheel box 8, such as the left and right side walls. The connection direction of the two second pull plate structures 2 can be adjusted, for example, by connecting the two second bends 212 of the two second pull plate structures 2 to the other ends of the corresponding two first pull plate structures 1 respectively, and connecting the two first bends 211 of the two second pull plate structures 2 to the corresponding two anchoring lugs 4 respectively, so as to fix the front traveling mechanism wheel box 8 to the anchoring position of the upper chord 13.

[0050] Since the two ends of the strut structure 3 are respectively connected to the two corresponding anchoring lugs 4, and the length of the strut structure 3 is adjustable, the strut structure 3 can be installed between the two anchoring lugs 4 of the upper chord 13 with a larger width. In short, the anchoring mechanism can be applied to the construction of steel truss arch bridges with two different widths of upper chord 13, improving the versatility of the anchoring mechanism. This makes the operation of the anchoring mechanism simple during the hoisting of steel truss arch bridge segments with upper chord 13 of different widths, which can greatly reduce operating costs and ensure safety performance.

[0051] Optionally, combined Figure 2As shown, the second pull plate structure 2 includes a second pull plate member 21, which includes a pull plate body 213, a first bending portion 211 and a second bending portion 212. The first bending portion 211 and the second bending portion 212 are respectively located at both ends of the extension direction of the pull plate body 213.

[0052] The first bending portion 211 of a second pull plate structure 2 is bent relative to the pull plate body 213 toward another second pull plate structure 2, and the second bending portion 212 of a second pull plate structure 2 is bent relative to the pull plate body 213 toward a direction away from another second pull plate structure 2.

[0053] Specifically, the second pull plate structure 2 may include at least one second pull plate member 21, and the pull plate body 213 may be a straight plate structure. The first bending portion 211 and the second bending portion 212 have opposite bending directions relative to the pull plate body 213. For example, the first bending portion 211 in one of the second pull plate structures 2 bends relative to the pull plate body 213 toward the other second pull plate structure 2, while the second bending portion 212 in the other second pull plate structure 2 bends relative to the pull plate body 213 toward the direction away from the other second pull plate structure 2. Therefore, the first bending portion 211, the pull plate body 213 and the second bending portion 212 of the second pull plate structure 2 may be constructed as an integral structure.

[0054] In this embodiment, since the first bend 211, the pull plate body 213, and the second bend 212 of the second pull plate structure 2 can be constructed as an integral structure, the mechanical strength of the second pull plate structure 2 can be improved, thereby ensuring the traction stability of the wheel box 8 of the front traveling mechanism. In addition, since the bending directions of the first bend 211 and the second bend 212 of each second pull plate structure 2 are opposite, the first interval formed between the two first bends 211 is greater than the second interval between the two second bends 212. This allows the assembly of the anchoring ear plate 4, which is connected to the other end of the first pull plate structure 1 and the anchoring ear plate 4 of two different widths of the upper chord rod 13, to be adapted by adjusting the different parts (or directions) of the second pull plate structure 2.

[0055] Optionally, combined Figure 3 As shown, the second pull plate structure 2 includes two second pull plate members 21 spaced apart. The other end of the first pull plate structure 1 is located between one end of the two second pull plate members 21 and is connected by a first fastener 23. The anchoring ear plate 4 is located between the other ends of the two second pull plate members 21 and is connected by a second fastener 24.

[0056] Specifically, the first fastener 23 and the second fastener 24 can be bolts or pins.

[0057] Each second pull plate structure 2 may include two second pull plate members 21 spaced apart, wherein the two second pull plate structures 2 can move along... Figure 2 and Figure 3 The coordinate system is spaced apart along the X-axis, and the two second pull plate structures 2 can be along... Figure 3 The coordinate system is symmetrically arranged along the Y-axis. The two second pull plate members 21 in each second pull plate structure 2 can move along... Figure 3 The X-axis in the coordinate system is spaced out and parallel.

[0058] In this embodiment, the end of the first pull plate structure 1 away from the front traveling mechanism wheel box 8 can be located between the ends of the two second pull plate members 21 in the same second pull plate structure 2, and the first pull plate structure 1 and the ends of the two second pull plate members 21 in the same second pull plate structure 2 can be connected and fixed by the first fastener 23; the anchoring ear plate 4 is located between the other ends of the two second pull plate members 21 in the same second pull plate structure 2, and the anchoring ear plate 4 and the other ends of the two second pull plate members 21 in the same second pull plate structure 2 can be connected and fixed by the second fastener 24, thereby increasing the connection area between the two ends of the second pull plate structure 2 and the first pull plate structure 1 and the anchoring ear plate 4 respectively, and correspondingly improving the connection stability between the two ends of the second pull plate structure 2 and the first pull plate structure 1 and the anchoring ear plate 4 respectively, so as to ensure the traction stability of the front traveling mechanism wheel box 8.

[0059] Optionally, combined Figure 3 As shown, the second pull plate structure 2 also includes a first spacer plate 22, which is disposed between the two pull plate bodies 213 in the second pull plate structure 2.

[0060] Specifically, the first partition plate 22 can be a plate-like structure, a block structure, a column structure, etc., and at least one first partition plate 22 can be provided between the two pull plate bodies 213 in the second pull plate structure 2.

[0061] The first partition plate 22 can be installed between the two pull plate bodies 213 by means of adhesive, snap-fit, bolt connection or other methods.

[0062] In this embodiment, when the first spacer 22 is disposed between the two pull plate bodies 213 in the second pull plate structure 2, the first spacer 22 moves along... Figure 4 The two ends of the X-axis in the coordinate system can respectively abut against the inner sidewalls of the two pull plate bodies 213, which is equivalent to increasing the mechanical strength of the second pull plate structure 2 and correspondingly reducing the possibility of deformation of the second pull plate structure 2 during the pulling of the front traveling mechanism wheel box 8, thereby ensuring the pulling stability of the front traveling mechanism wheel box 8.

[0063] Optionally, combined Figure 3 As shown, the second pull plate structure 2 further includes a second spacer 25, and a second spacer 25 is provided between the other end of the first pull plate structure 1 and one end of the second pull plate member 21; another second spacer 25 is provided between the other end of the second pull plate member 21 and the anchoring ear plate 4.

[0064] Specifically, the second spacer 25 can be a plate-shaped structure, a block-shaped structure, etc. At least one second spacer 25 can be provided between the two pull plate bodies 213 in the second pull plate structure 2 and the other end of the first pull plate structure 1, and connected by the first fastener 23; at least one second spacer 25 can be provided between the end of the second pull plate member 21 away from the first pull plate structure 1 and the anchoring ear plate 4, and connected by the second fastener 24.

[0065] In this embodiment, different second spacers 25 are respectively provided between the end of the first pull plate structure 1 away from the front travel mechanism wheel box 8 and the end of the second pull plate member 21, and between the other end of the second pull plate member 21 and the anchoring ear plate 4. This is equivalent to increasing the connection area between the two ends of the second pull plate structure 2 and the first pull plate structure 1 and the anchoring ear plate 4, respectively, thereby enhancing its connection strength and further ensuring the traction stability of the front travel mechanism wheel box 8.

[0066] Optionally, combined Figure 4 As shown, the first pull plate structure 1 has an adjustment hole 11 at one end away from the front traveling mechanism wheel box 8, and the first fastener 23 is used to adjust its position within the adjustment hole 11.

[0067] Specifically, the adjustment hole 11 can be a rectangular hole or an oblong hole, and the position of the first fastener 23 within the adjustment hole 11 can be adjusted.

[0068] In this embodiment, for example, since the first fastener 23 is connected to the adjustment hole 11 of the first pull plate structure 1 and one end of the pull plate member of the second pull plate structure 2, the position of the first fastener 23 within the adjustment hole 11 can be moved. This not only ensures that the first fastener 23 can be smoothly inserted into the connection between the first pull plate structure 1 and the second pull plate structure 2, but also that the setting of the adjustment hole 11 is equivalent to realizing the length adjustment of the extension direction of the first pull plate structure 1 and the second pull plate member 21. Furthermore, the design of the adjustment hole 11 not only facilitates on-site installation, but also provides a safe and reliable inspection condition for the brake inspection of the winch.

[0069] Optionally, combined Figure 5 and Figure 6As shown, the anchoring mechanism applicable to different upper chord 13 widths includes two support rod structures 3. The two ends of one support rod structure 3 are respectively connected to one end of the second pull plate member 21 located between the two anchoring lugs 4, and the two ends of the other support rod structure 3 are respectively connected to the other ends of the two second pull plate members 21 in the second pull plate structure 2.

[0070] Specifically, the anchoring mechanism applicable to different upper chord 13 widths may include two strut structures 3, wherein, combined with Figure 5 As shown, the two ends of the shorter strut structure 3 are respectively connected to the ends of the two corresponding second tie plate members 21 in the two second tie plate structures that are away from the first tie plate structure 1. At this time, the length of the strut structure 3 along the X-axis can be L1, and the shorter strut structure 3 can be the end with a reduced width. The two ends of the longer strut structure 3 are respectively connected to the connection points of the two corresponding second tie plate members in the two second tie plate structures and the first tie plate structure 1. At this time, the length of the strut structure 3 along the X-axis can be L, and the longer strut structure 3 can be the end with a increased width. Since L1 is less than L, the longer strut structure 3, as the end with an increased width, can be used for the anchoring operation of the steel beam segment of the upper chord 13 when connected to the first tie plate structure 1.

[0071] Combination Figure 6 As shown, the two ends of the longer strut structure 3 are respectively connected to the ends of the two second tie plate members 21 in the two second tie plate structures that are away from the first tie plate structure 1. At this time, the length of the strut structure 3 along the X-axis can be L2, and the longer strut structure 3 can be the end with increased width. The two ends of the shorter strut structure 3 are respectively connected to the connection points of the two second tie plate structures 2 and the two first tie plate structures 1. At this time, the length of the strut structure 3 along the X-axis can be L, and the longer strut structure 3 can be the end with decreased width. Since L2 is greater than L, the longer strut structure 3, as the end with increased width, can be used for anchoring operations of steel beam segments with large width upper chord 13 when connected to the anchoring ear plate 4.

[0072] Optionally, combined Figure 7 As shown, the strut structure 3 includes two mounting seats 31, two hinge joints 32, and a telescopic rod 33. The two mounting seats 31 are respectively mounted on the corresponding second pull plate members 21. The two hinge joints 32 are respectively rotatably connected to the corresponding mounting seats 31 through rotating shafts. The two ends of the telescopic rod 33 are respectively connected to the corresponding hinge joints 32. The length of the telescopic rod 33 is adjustable.

[0073] Specifically, the extension direction of the telescopic rod 33 can be parallel to... Figure 7The X-axis is parallel; the two ends of the telescopic rod 33 are respectively connected to the corresponding hinge joints 32, and the two mounting seats 31 are respectively installed on the second pull plate members 21 of the two second pull plate structures 2. Each hinge joint 32 can be rotatably connected to the corresponding mounting seat 31 through a rotating shaft, so that the end of the telescopic rod 33 can rotate relative to the corresponding mounting seat 31 through the hinge joint 32.

[0074] The telescopic rod 33 can be adjusted in length by the operator.

[0075] In this embodiment, since the length of the telescopic rod 33 is adjustable, and the ends of the telescopic rod 33 are rotatably connected to the mounting base 31 on the corresponding second pull plate structure 2 through the hinge joint 32, the length of the telescopic rod 33 can be adjusted according to the upper chord rod 13 of different widths, so as to improve the applicability of the telescopic rod 33.

[0076] The telescopic rod 33 can adopt a telescopic tube structure with adjustable length. For example, the telescopic rod 33 includes at least two telescopic tube sections, with two adjacent telescopic tube sections sleeved on each other. Multiple adjustment holes are provided on the telescopic tube sections along their axial direction. After the length of the telescopic rod 33 is adjusted, the length of the telescopic rod 33 can be locked by inserting bolts into different adjustment holes on the two telescopic tube sections.

[0077] The telescopic member 33 can also be used in other ways, for example, optionally, in combination with Figure 7 As shown, the telescopic rod 33 includes a first connecting rod 331 and two second connecting rods 332. The two ends of the first connecting rod 331 are respectively threaded to one end of the two second connecting rods 332, and the other ends of the two second connecting rods 332 correspond to the hinge joint 32.

[0078] Specifically, the first connecting rod 331 can be located in the middle of the two second connecting rods 332. The two ends of the first connecting rod 331 can be connected to the corresponding second connecting rods 332 by means of threaded connection. By operating the first connecting rod 331 to rotate relative to the two second connecting rods 332, the length of the telescopic rod 33 can be adjusted. After the length is adjusted, the position of the telescopic rod 33 after length adjustment can be locked by the threaded engagement of the first connecting rod 331 and the second connecting rod 332.

[0079] Optionally, combined Figure 8 As shown, the anchoring mechanism applicable to different upper chord 13 widths also includes an anchoring box beam 5 and a third fastener 6. The anchoring box beam 5 is connected to the anchoring ear plate 4 through the third fastener 6. The anchoring box beam 5 is provided with a first pulley block 7, and the front traveling mechanism wheel box 8 is provided with a second pulley block 9. The first pulley block 7 and the second pulley block 9 are used to connect the winch through the wire rope 10.

[0080] Specifically, the first fastener 23 can be a bolt fastener or a pin.

[0081] The opposite ends of the anchor box girder 5 can be connected to the corresponding anchor lugs 4 by at least two third fasteners 6.

[0082] A first pulley block 7 can be installed on the anchor box beam 5, and a second pulley block 9 can be set at the end of the front traveling mechanism wheel box 8, for example, at the front end. The winch can be set in the area above the anchoring mechanism. The first pulley block 7 can be a movable pulley block, and the second pulley block 9 can be a fixed pulley block.

[0083] In this embodiment, since the anchor box beam 5 can be connected to the anchor ear plate 4 through the third fastener 6, and the anchor ear plate 4 can be fixed to the upper part of the upper chord 13, the anchor box beam 5 connected to the anchor ear plate 4 can effectively increase the load tensile strength of the anchor ear plate 4 on the front traveling mechanism wheel box 8.

[0084] The wire rope 10 can be wound around the first pulley block 7 and the second pulley block 9 and connected to the winch. By rotating the winch, the front traveling mechanism wheel box 8 is pulled to move along the extension direction of the upper chord 13, thereby providing traction force for the front traveling mechanism wheel box 8 of the full-rotation climbing crane. After the traction travel is in place, the crane anchor system is converted (from the traction traveling system to the anchoring system). Only after the whole machine system conversion is completed can the steel beam segment be hoisted.

[0085] Another embodiment of this utility model provides a climbing crane, including a front traveling mechanism wheel box 8 and an anchoring mechanism as described in the above embodiment, suitable for different upper chord widths.

[0086] Specifically, a travel track 12 can be laid on the upper part of the upper chord 13, and a slide can be provided at the bottom of the front travel mechanism wheel box 8. The slide is slidably connected to the travel track 12 so that the front travel mechanism wheel box 8 can be pulled to move on the travel track 12 under the action of the winch and the wire rope.

[0087] In this embodiment, the front traveling mechanism wheel box 8 can be pulled to the anchoring position of the upper chord 13 and the load transferred in the following manner, as illustrated in the example:

[0088] Combination Figure 9As shown, during the traction phase, the winch, the first pulley block 7, and the second pulley block 9 can be connected by the wire rope 10. The winch reduces the distance between the first pulley block 7 and the second pulley block 9 by winding the rope, causing the front traveling mechanism wheel box 8 to move upward along the traveling track 12. When the winch pulls the front traveling mechanism wheel box 8 to the position (moving to the foremost position of the adjusting plate of the first pull plate structure 1, at which point the front traveling mechanism wheel box 8 has a 20mm retraction range), the traction winch can be easily braked and retracted (within 10mm of retraction distance) and intermittently braked to test the braking function of the traction system. The design of the adjusting hole 11 not only facilitates on-site installation but also provides a safe and reliable testing condition for the brake testing of the traction winch.

[0089] During the climbing process, the front traveling mechanism wheel box 8 of the entire crane will not slide down when pulled by the wire rope 10. When the crane is tested for braking, the rope is released by the winch and the entire machine slides down. Then the brake is applied to verify whether the entire machine will move down under the action of the brake and to verify whether the brake function is normal.

[0090] Transition Phase: Combination Figure 8 As shown, after the front traveling mechanism wheel box 8 is pulled into position (anchoring position of the upper chord 13), it enters the conversion state, connecting the second fastener 24 of the second pull plate structure 2 and the anchoring ear plate 4. Then, the braking function is tested. After the test is completed, the wire rope 10 is gradually released by the winch, so that all the load of the front traveling mechanism wheel box 8 is gradually transferred from the winch to the anchoring ear plate 4 and the anchoring box beam 5. In short, the traction traveling system of the winch is converted to the anchoring system of the anchoring ear plate.

[0091] Anchoring stage: Combination Figure 10 As shown, the beam lifting operation can only be carried out after the load of the wheel box 8 of the current traveling mechanism has been completely transferred to the anchoring lug 4.

[0092] in, Figure 8 to Figure 10 The dotted line marked with the letter "D" in the middle can refer to the horizontal baseline where the bottom of the running track is located.

[0093] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
