Abstract
Description
Technical Field
[0001] The utility model relates to the field of shipbuilding gantry crane manufacturing and installation, in particular to a shipbuilding gantry crane traveling mechanism gauge adjusting device. Background Art
[0002] As the lifting capacity, span, and lifting height of shipyard gantry cranes continue to increase, their overall weight and travel mechanism dimensions are also growing. In the past, when track gauge deviation or wheel-track interference occurred in the travel mechanism, the common adjustment method was to tighten the travel mechanism's adjusting bolts. This adjustment was achieved through the lateral force generated by tightening the bolts and the continuous reciprocating operation of the crane's travel mechanism. This method had a long operation cycle and could not accurately control the adjustment amount for travel mechanisms with multiple wheels. Moreover, for gantry cranes with excessive overall weight and bulky travel mechanisms, the lateral force provided by the adjusting bolts could not be effectively transmitted to the wheels, thus failing to resolve the problems of track gauge deviation and wheel-track interference. Utility Model Content
[0003] In response to one or more deficiencies in the above-mentioned prior art, the utility model provides a shipbuilding gantry crane traveling mechanism gauge adjustment device, which can adjust the suspended traveling mechanism components to the required position and can effectively control the adjustment distance to achieve a more precise adjustment process.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A track gauge adjustment device for a shipbuilding gantry crane traveling mechanism comprises a traveling mechanism and a traveling mechanism assembly connected at both sides of the lower end of the traveling mechanism, wherein the traveling mechanism and the traveling mechanism assembly are hingedly connected via a hinge shaft, and a track gauge adjustment mechanism is installed below the hinge shaft;
[0006] The track gauge adjustment mechanism includes a tooling beam and a bracket tooling. The bracket tooling is located above the tooling beam and is used to support the walking mechanism assembly. A track tread is provided on the top of the tooling beam, and an adjustment rail is welded on the track tread. The adjustment rail is slidably connected to the bracket tooling. The bracket tooling can slide along the adjustment rail to adjust the distance between the walking mechanism assemblies on both sides, thereby realizing track gauge control of the walking mechanism.
[0007] As a further implementation method, a hydraulic cylinder is provided at the end of the tooling beam, and the telescopic rod of the hydraulic cylinder is connected to the bracket tooling. The bracket tooling is driven to move horizontally on the adjustment track through the telescopic movement of the hydraulic cylinder.
[0008] As a further implementation, a first hinge support is welded to the end of the tooling beam, and the tail of the hydraulic cylinder is fixedly connected to the first hinge support and further fixedly connected to the tooling beam.
[0009] As a further implementation method, a second hinge support is welded to the end of the bracket tooling, and the free end of the telescopic rod of the hydraulic cylinder is fixedly connected to the second hinge support. When the telescopic rod is extended or retracted, the bracket tooling is driven to move horizontally through the second hinge support.
[0010] As a further implementation method, a polytetrafluoroethylene plate is fixed to the bottom of the bracket fixture to reduce the friction coefficient and facilitate the straight-line movement of the bracket fixture along the adjustment track.
[0011] As a further implementation, the polytetrafluoroethylene plate and the bracket fixture are fixed by bolts.
[0012] As a further implementation method, a cushion is further provided at the bottom of the tooling beam, and the cushion is placed on the ground to support the tooling beam.
[0013] As a further implementation method, a jack is provided on the top of the bracket tooling to lift the walking mechanism assembly, thereby reducing the pressure of the walking mechanism assembly on the hinge shaft automatically, and further reducing the friction between the walking mechanism assembly and the hinge shaft.
[0014] As a further implementation, an adjusting bolt perpendicular to the direction of the adjustment track is provided on the side of the walking mechanism.
[0015] As a further implementation, the adjusting bolt is mounted on the balancing beam of the traveling mechanism, and the adjusting bolt is located above the hinge axis, so that the traveling mechanism to be adjusted is displaced in a direction perpendicular to the ground track.
[0016] By adopting the above technical solution, the beneficial effects of the utility model are as follows:
[0017] 1. The utility model uses the tooling beam, adjustment rail and bracket tooling to move the walking mechanism components on both sides to the required position after the walking mechanism components are vacated, thereby adjusting the walking mechanism gauge and effectively controlling the moving distance, thereby achieving precise adjustment of the gauge and solving the problems of deviation in the walking mechanism gauge and interference between the wheels and the track.
[0018] 2. In the present invention, the bracket fixture is driven by a hydraulic cylinder to drive the movement of the walking mechanism components. The adjustment process is efficient and controllable, and easy to operate.
[0019] 3. The utility model installs an oiled polytetrafluoroethylene plate at the bottom of the bracket fixture, which can reduce the friction coefficient and effectively reduce the friction force when the bracket fixture moves along the track, which is conducive to improving the adjustment efficiency.
[0020] 4. All structural components of the present invention are detachable and can be reused during the life cycle, which reduces costs and has good economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0030] Example 1
[0031] In a typical embodiment of the present application, a device for adjusting the track gauge of a shipbuilding gantry crane traveling mechanism is provided. Figure 1-4 As shown, it includes a traveling mechanism 1 and traveling mechanism components 2 connected on both sides of the lower end of the traveling mechanism. The traveling mechanism 1 and the traveling mechanism components 2 on both sides are hingedly connected through hinge shafts 3 respectively. The lower end of the hinge shaft 3 is provided with a track gauge adjustment mechanism 4 for adjusting the distance between the traveling mechanism components on both sides, thereby adjusting the track gauge of the traveling mechanism.
[0032] Specifically, if Figure 3-4 As shown, the track gauge adjustment mechanism 4 includes a fixture beam 41 and a bracket fixture 43. The bracket fixture 43 is located above the fixture beam 41 and is used to support the running gear components on top. An adjustment track 42 is welded to the top of the fixture beam 41. The fixture beam 41 is slidably connected to the bracket fixture 43 via the adjustment track. The bracket fixture 43 can slide along the adjustment track 42 to adjust the spacing between the running gear components on both sides, achieving track gauge adjustment and precise control of the running gear.
[0033] In this embodiment, Figure 3 As shown, a hydraulic cylinder 44 is installed at the end of the tooling beam 41. The telescopic rod of the hydraulic cylinder 44 is connected to the bracket tooling 43. The extension and contraction of the hydraulic cylinder 44 drives the bracket tooling 43 to move horizontally on the adjustment track 42. Specifically, a first hinge support 48 is welded to the end of the tooling beam 41, and a second hinge support 49 is welded to the end of the bracket tooling 43. The tail of the hydraulic cylinder 44 is fixedly connected to the tooling beam 41 via the first hinge support 48, and the free end of the telescopic rod of the hydraulic cylinder 44 is fixedly connected to the bracket tooling 43 via the second hinge support 49. When the telescopic rod of the hydraulic cylinder is extended or contracted, the bracket tooling is driven to move horizontally along the adjustment track via the second hinge support.
[0034] In this embodiment, a polytetrafluoroethylene plate 45 is fixed to the bottom of the bracket fixture 43, and grease is applied to the surface of the polytetrafluoroethylene plate to reduce the friction coefficient, thereby reducing the friction force when the bracket fixture moves along the adjustment track, which can reduce the driving force required by the hydraulic cylinder, and more conveniently and efficiently push the walking mechanism assembly to shift in the direction perpendicular to the track. The polytetrafluoroethylene plate 45 is fixed to the bracket fixture 43 by bolts, which is convenient for installation and disassembly. It should be noted that the track here refers to the trolley walking mechanism track of the gantry crane, which is the track installed on the ground by the civil engineering for the operation of the equipment. It is used here as a direction reference to illustrate the movement direction of the construction adjustment.
[0035] In this embodiment, Figure 3-4As shown, a cushion 46 is provided at the bottom of the tooling beam 41. The cushion 46 is placed on the ground to support the tooling beam. A jack 47 is placed on top of the bracket 43. The top of the jack 47 supports the running gear assembly 2. When adjusting the track gauge, the running gear assembly can be lifted to a certain height to reduce the pressure of the running gear assembly's own weight on the hinge axis, thereby reducing the friction between the running gear assembly and the hinge axis.
[0036] In this embodiment, Figure 3 As shown, an adjustment bolt 13 is provided on the side of the running mechanism 1, perpendicular to the direction of the adjustment track. Tightening the adjustment bolt with a wrench generates thrust to move the running mechanism, serving as an auxiliary drive for the running mechanism. The adjustment bolt 13 is mounted on the running mechanism's equalizing beam 11 and is located above the hinge axis 3 to achieve displacement of the running mechanism in a direction perpendicular to the ground track.
[0037] In addition, during operation, the jacking of the walking mechanism is completed by a jacking device, such as Figure 2 As shown, the jacking device includes a stool 46 placed on the ground, a jack 47 is set above the stool 46, a lifting beam 12 is installed on the top of the jack 47, and the balancing beam 11 of the walking mechanism is placed on the lifting beam 12. It is lifted to a certain height by the bottom stool and the jack, and then the walking mechanism components on both sides are adjusted.
[0038] The workflow of this embodiment is:
[0039] Step 1: Arrange the traveling mechanism 1, the traveling mechanism assembly 2, the lifting device for lifting the traveling mechanism, and the gauge adjustment mechanism 4 on site.
[0040] Step 2: Use Figure 2 The jacking device shown places the running gear that needs to adjust the track gauge on the jacking beam 12 and then jacks it off the ground.
[0041] Step 3: Start the jack 47, which slowly loads and lifts the traveling mechanism components at both ends of the entire vacated traveling mechanism, thereby reducing the pressure of the traveling mechanism components' deadweight on the hinge shaft.
[0042] Step 4: Tighten the adjusting bolt 13 of the traveling mechanism in the direction perpendicular to the track, and start the hydraulic cylinder 44. The horizontal thrust of the hydraulic cylinder pushes the traveling mechanism component to be adjusted horizontally along the adjustment track, thereby achieving the purpose of adjusting the track gauge.
[0043] It should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Those skilled in the art will appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
