Description

Technical Field

[0001] This application relates to the technical field of differential adjustment of track gantry crane travel, and in particular to a differential adjustment mechanism for arc-shaped track gantry crane travel in a precast beam yard for a mountain highway. Background Technology

[0002] Gantry cranes, also known as cranes, are multi-action lifting machines that can vertically lift and horizontally move heavy objects within a certain range.

[0003] In most existing mountain beam yards, gantry cranes are used to assist in the lifting and transportation of precast components used in highways during the processing of precast components. However, due to the influence of mountainous terrain and the lack of large flat areas, and for the sake of convenience, mountain beam yards are basically built along the roadbed. Since the roadbed is curved, the gantry crane rails are designed to be curved, which makes traditional straight-track gantry crane wheels unsuitable, creating limitations and hindering their widespread use.

[0004] Therefore, those skilled in the art have provided a micro-differential adjustment mechanism for the travel of an arc-shaped track gantry crane in a precast beam yard for mountain highways to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problem mentioned in the background art that the curved design of crane tracks due to the mountainous terrain makes traditional straight-track gantry cranes unsuitable, thus limiting their application and hindering widespread use, this application provides a micro-delay adjustment mechanism for curved track gantry cranes used in precast beam yards of mountainous highways.

[0006] The technical solution provided in this application for a micro-differential adjustment mechanism for an arc-shaped track gantry crane traveling in a precast beam yard for a mountainous highway is as follows: It includes four adjustment seats, each with a first adjustment component installed on its top inner wall. Each first adjustment component includes two U-shaped connecting frames, both of which are rotatably connected to the top inner wall of their respective adjustment seats. Each of the two U-shaped connecting frames has a track wheel rotatably connected to its inner wall, and both track wheels are in contact with the surface of an external track. A second adjustment component is rotatably installed on the top side of each of the four adjustment seats, and the same gantry crane is fixedly installed on the top side of each of the four second adjustment components. The width of the inner contact surface of each of the eight track wheels is two centimeters greater than the cross-sectional width of the external track, and the inner contact surfaces of each of the eight track wheels are designed with rounded corners.

[0007] Preferably, the second adjustment component includes a connecting shaft, which is fixedly connected to the top side of the corresponding adjustment seat. An arc-shaped connecting block is laterally rotatably connected to the top end of the connecting shaft, and a connecting sleeve is flipped to the outside of the arc-shaped connecting block. Four connecting sleeves are used for fixed connection with the same door hanger.

[0008] Preferably, baffles are fixedly connected to the inner walls of the front and rear sides of the four adjustment seats.

[0009] Preferably, two marker lights are fixedly installed on the top side of each of the four adjustment seats.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. By setting up a U-shaped connecting frame, the gantry crane is moved by an external tractor, which facilitates the lifting and transportation of precast components for highways. During the movement of the gantry crane, all eight rail wheels are in point contact with the surface of the track. When the track is curved due to the terrain, the gantry crane can move to this point, and the rail wheels can be finely adjusted to adapt to the curvature of the track by utilizing the rotatable characteristic of the U-shaped connecting frame. This method allows the gantry crane to move on curved tracks, effectively reducing the limitations in use and facilitating its widespread adoption.

[0012] 2. By setting up an arc-shaped connecting block, when the gantry crane moves and is affected by the undulating terrain, the arc-shaped connecting block and the connecting sleeve will undergo a suitable angle flipping micro-adjustment, thereby ensuring that the gantry crane always maintains a vertical state when traveling through undulating terrain and avoiding tilting.

[0017] The following will be combined with the appendix Figure 1-3The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] This application discloses a micro-delay adjustment mechanism for an arc-shaped track gantry crane traveling in a precast beam yard for a mountain highway, referring to... Figure 1-3 The system includes four adjusting seats 1, each with a first adjusting component mounted on its top inner wall. Each first adjusting component includes two U-shaped connecting frames 2, each rotatably connected to the corresponding top inner wall of the adjusting seat 1. Each U-shaped connecting frame 2 has a track wheel 3 rotatably connected to its inner wall, and both track wheels 3 are in contact with the surface of the external track. Second adjusting components are rotatably mounted on the top of each of the four adjusting seats 1. A single door hanger 4 is fixedly mounted on the top of each of the four second adjusting components. The width of the inner contact surface of the eight track wheels 3 is two centimeters greater than the cross-sectional width of the external track, and the inner contact surfaces of the eight track wheels 3 are all inverted... The design incorporates rounded corners. By using a U-shaped connecting frame 2, the gantry crane 4 is moved by an external tractor, facilitating the lifting and transport of precast components for highways. During the movement of the gantry crane 4, all eight rail wheels 3 are in point contact with the surface of the track. When the track is affected by the terrain and can only be constructed in a curved manner, the gantry crane 4 moves to this point, and the rail wheels 3 utilize the rotatable characteristic of the U-shaped connecting frame 2 to make micro-adjustments to adapt to the curvature of the track. This method allows the gantry crane 4 to move on curved tracks, effectively reducing limitations during use and promoting its widespread adoption.

[0019] In this application, the second adjustment component includes a connecting shaft 5, which is fixedly connected to the top side of the corresponding adjustment seat 1. The top end of the connecting shaft 5 is laterally rotatably connected to an arc-shaped connecting block 6, and the outer side of the arc-shaped connecting block 6 is flipped to connect to a connecting sleeve 7. Four connecting sleeves 7 are used to be fixedly connected to the same gantry crane 4. By setting the arc-shaped connecting block 6, when the gantry crane 4 moves and is affected by the undulation of the terrain, the arc-shaped connecting block 6 and the connecting sleeve 7 will undergo a micro-adjustment of the applicable angle flip, thereby ensuring that the gantry crane 4 always maintains a vertical state when passing through undulating terrain and avoiding tilting.

[0020] In this application, baffles 8 are fixedly connected to the inner walls of the front and rear sides of the four adjustment seats 1. By setting baffles 8, when the adjustment seat 1 moves along the track, the baffles 8 can clean up the garbage such as gravel particles accumulated on the track surface, so as to avoid affecting the normal movement of the gantry crane 4.

[0021] In this application, two marker lights 9 are fixedly installed on the top side of each of the four adjustment seats 1; by setting the marker lights 9, when the gantry crane 4 is used in a dim environment, the multiple marker lights 9 can achieve a warning effect, thereby improving the safety of use in dim environments.

[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0023] The implementation principle of the arc-shaped track gantry crane travel differential adjustment mechanism in the precast beam yard of a mountain highway according to this application embodiment is as follows: During use, an external tractor pulls the gantry crane 4 to move it, facilitating the lifting and transport of precast components for the highway. During the movement of the gantry crane 4, all eight track wheels 3 are in point contact with the track surface. When the track is curved due to terrain influences, the gantry crane 4 moves to this point, and the track wheels 3, utilizing the rotatable characteristic of the U-shaped connecting frame 2, can make adaptive angle micro-adjustments to the track curvature. This method allows the gantry crane 4 to move on curved tracks. It effectively reduces the limitations in the use process and is conducive to the promotion of use. When the gantry crane 4 moves, it will be affected by the undulation of the terrain. The arc-shaped connecting block 6 and the connecting sleeve 7 will undergo a micro-adjustment of the applicable angle flip, so as to ensure that the gantry crane 4 always maintains a vertical state when passing through undulating terrain and avoids tilting. When the adjusting seat 1 moves along the track, the baffle 8 can be used to clean up the debris such as gravel particles accumulated on the track surface to avoid affecting the normal movement of the gantry crane 4. When the gantry crane 4 is used in a dark environment, multiple indicator lights 9 can be used to achieve a warning function, thereby improving the safety of use in dark environments.

[0024] Additionally: In the gantry crane design of this case, the curvature of the double track causes a difference in the span of the two tracks at the same location. Therefore, a frequency converter is used to adjust the differential speed of the track wheel 3 in this case, thereby preventing derailment. The application of frequency converters is very mature in the field of vehicles, so it will not be elaborated on further. As for the installation location and method, the workers will control them according to the site conditions during the actual installation process to ensure normal use.

[0025] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
