Description

Technical Field

[0001] The invention relates to the field of travel drive devices for bridge engineering hoisting equipment, and in particular to a novel modular push-pull double-acting hydraulic clamp combined three-dimensional self-guided sliding device. Background Art

[0002] In the field of heavy object handling and bridge construction, various mechanical devices are usually needed to achieve the movement and positioning of heavy objects. These devices are often complex in structure, cumbersome to operate, and lack flexibility and adaptability. Especially in bridge construction, large structural parts such as steel beams need to be accurately handled and positioned, which puts higher requirements on handling equipment.

[0003] At present, a single-acting wedge-type rail clamp is used in bridge construction. The wedges inside the rail clamp clamp the two sides of the rail head to provide friction resistance, and then the cylinder pushes the steel beam forward to slide in one direction.

[0004] On the one hand, due to the unidirectional nature of the wedge, this rail clamp can only generate forward thrust, but cannot generate backward pulling force, nor can it return automatically; on the other hand, during the process of the wedge clamping the steel rolling, it is necessary to slide backward over a long distance to eliminate the gap between the wedge and the two sides of the rail head in order to achieve clamping, which will cause asynchrony when multiple rail clamps are used in combination at the same time.

[0005] Therefore, it is urgent to develop a new modular push-pull double-acting hydraulic clamp combined with a three-dimensional self-guided sliding device for engineering construction. Summary of the invention

[0006] The main purpose of the present invention is to provide a modular push-pull double-acting hydraulic clamp combined with a three-dimensional self-guided sliding device. The modular push-pull double-acting hydraulic clamp clamps the rail head to form an Ω-shaped whole, generating multi-directional gripping force and large non-slip friction resistance. The longitudinal horizontal oil cylinder connected to the hydraulic clamp pushes the two-dimensional hydraulic jack slide seat through telescopic action to achieve longitudinal sliding, and carries steel beams or heavy objects to slide forward or backward along the track for a long distance. The longitudinal horizontal oil top pushes and pulls the two-dimensional hydraulic jack slide seat to achieve forward or backward sliding; the two-dimensional hydraulic jack installed on the slide seat is used to support the heavy object and accurately adjust the lateral position and height size of the heavy object. The longitudinal horizontal oil top and the two-dimensional jack coordinate to achieve three-dimensional spatial action, which is used to accurately adjust the three-dimensional spatial position of the steel beam or heavy object. The modular push-pull double-acting hydraulic clamp can be used in parallel or series combination according to the weight of the steel beam or heavy object; the modular push-pull double-acting hydraulic clamp can push forward or pull backward in both positive and negative directions, and can be used as a travel drive device for bridge cranes and gantry cranes, providing a new type of lightweight and optional travel drive device for large-scale lifting equipment in engineering construction.

The modular push-pull double-acting hydraulic clamp 1 can push forward or pull backward in both positive and negative directions, and can be used as a travel drive device for bridge cranes and gantry cranes. The following is a specific implementation of the above application:

[0073] Implementation method 1. Vertical series combination application:

[0074] When it is necessary to increase the clamping force or accommodate longer heavy objects, this can be achieved by connecting multiple modular push-pull double-acting hydraulic clamps 1 in series. Each modular push-pull double-acting hydraulic clamp 1 is connected via a connecting ear plate 201 on its frame 102. An odd number of connecting ear plates 201 are inserted between an even number of connecting ear plates 201 and connected together via a connecting pin 301, thereby connecting adjacent modular push-pull double-acting hydraulic clamps 1 to form a straight line, ensuring synchronous clamping and release.

[0075] The connecting ear plate of each modular push-pull double-acting hydraulic clamp 1 is designed with a standardized connection interface, such as a pin hole, to facilitate quick connection and disassembly. When connected in series, a dedicated connecting pin 301 is used to ensure the stability and reliability of the connection.

[0076] Implementation method 2. Horizontal parallel combination application:

[0077] For heavy objects with a larger width or requiring multiple clamping points, multiple modular push-pull double-acting hydraulic clamps 1 can be configured in parallel. The parallel modular push-pull double-acting hydraulic clamps 1 are installed on the same horizontal plane, and different parts of the heavy object are independently clamped by their respective clamping cylinders 2.

[0078] The parallel modular push-pull double-acting hydraulic clamps 1 are connected via a common frame 102 or a dedicated connecting plate; the connecting plate is designed with multiple fixing points to ensure the stability and synchronization of all the parallel modular push-pull double-acting hydraulic clamps 1 during operation.

[0079] Implementation method 3. Two-dimensional hydraulic jack slide single-side double-track or single-side single-track support application:

[0080] Usage: Select double-track or single-track support mode according to the width and space limitation of the transport path; in double-track support, both sides of the lower surface of the two-dimensional hydraulic jack slide 3 are provided with slide rails, while in single-track support, only one side is provided with slide rails;

[0081] When single-side double-track is used, multiple modular push-pull double-acting hydraulic clamps 1 are synchronized to push the steel beam forward to initially position, and after initially position, multiple degrees of freedom are adjusted in three-dimensional space to achieve precise alignment with the erected steel beam. Multiple modular push-pull double-acting hydraulic clamps 1 are synchronized to return to the original position, and then transported and pushed again to assemble and align the next beam section;

[0082] When a single-sided monorail is used, multiple modular push-pull double-acting hydraulic clamps 1 are synchronized to push the steel beam forward to initially position, and after initially position, multiple degrees of freedom are adjusted in three-dimensional space to achieve precise alignment with the erected steel beam. Multiple modular push-pull double-acting hydraulic clamps are synchronized 1 and return to their original positions, ready to transport and push the next beam section again for assembly and alignment;

[0083] In the above working process, multiple modular push-pull double-acting hydraulic clamps 1 perform the following work: the modular push-pull double-acting hydraulic clamp 1 clamps and pushes the heavy object to slide forward; the modular push-pull double-acting hydraulic clamp 1 releases and automatically slides forward; the modular push-pull double-acting hydraulic clamp 1 clamps and pushes the heavy object to slide forward; the modular push-pull double-acting hydraulic clamp 1 releases and automatically slides forward; the modular push-pull double-acting hydraulic clamp 1 releases and automatically slides backward; the modular push-pull double-acting hydraulic clamp 1 clamps and pulls the heavy object to slide backward.
