Description

Technical Field

[0001] This utility model relates to the field of truss crane technology, specifically to a deck truss crane hoisting connection seat structure. Background Technology

[0002] The deck is an important component of the ship's hull. It is a planar structure located above the inner bottom plate in the ship's structure. It is used to cover the internal space of the ship and horizontally divide it into layers. The deck truss structure is a lattice-type beam structure that is connected to the deck through riveting, bolting and other connection methods.

[0003] Currently, during the installation of existing deck trusses, it is generally necessary to use a truss crane to lift the prefabricated truss structure from the ground to the designed construction position. The existing truss crane's lifting connector has poor stability after being connected to the truss. During the lifting process, the center of gravity of the truss lifting point may shift due to the connector being too light or the structure being asymmetrical, which may affect the lifting safety of the truss.

[0004] Based on this, the present invention designs a deck truss hoisting connection seat structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a deck truss hoisting connection structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deck truss hoisting connection seat structure, including a cross frame, a fixed frame, positive and negative threaded rods, limiting rods, a hoisting bearing plate, a connecting plate, a support frame, a clamping mechanism, and lifting lugs. The front and rear ends of the center of the cross frame are fixedly connected to the fixed frame. The upper end of the fixed frame is symmetrically provided with guide grooves. Limiting rods are symmetrically arranged left and right inside each fixed frame. Positive and negative threaded rods are arranged between the two limiting rods. The positive and negative threaded rods penetrate the cross frame, and their two ends are movably installed inside the front and rear fixed frames of the cross frame. Hoisting bearing plates are movably installed inside the fixed frames at both ends of the cross frame. Connecting plates are fixedly connected to the front and rear ends of both sides of the cross frame. A support frame is installed on the two connecting plates on the same side. A clamping mechanism is movably installed on the cross frame between the two connecting plates on the same side. Two lifting lugs are symmetrically fixedly connected to the upper end of the cross frame.

[0007] As a preferred technical solution of this utility model, the hoisting bearing plate includes a plate body, a sliding block and a guide block. The upper end of the plate body is provided with a sliding block, and the lower ends of both sides of the sliding block are symmetrically provided with guide blocks. The sliding block is helically connected to the positive and negative threaded rods and slidably connected to two limiting rods in the same side of the fixed frame.

[0008] As a preferred technical solution of this utility model, the guide blocks symmetrically arranged at the lower ends of both sides of the sliding block are respectively slidably arranged in the guide grooves symmetrically opened at the upper end of the fixed frame on the same side.

[0009] As a preferred technical solution of this utility model, the support frame includes a base plate, uprights, threaded posts, and nuts. The upper surface of the base plate is flush with the upper surface of the bent plate at the bottom of the plate. Two uprights are symmetrically fixedly connected to the base plate. Each of the two uprights has a threaded post at its upper end. The threaded posts at the upper ends of the uprights pass through the connecting plate on the same side, and each threaded post is screwed with a nut.

[0010] As a preferred technical solution of this utility model, the pressing mechanism includes a spiral rod, a limiting block and a pressing block. The lower end of the spiral rod is provided with a limiting block, which is movably connected to the inside of the pressing block. The pressing block is set in a corresponding groove opened at the lower end of the connecting plate.

[0011] As a preferred embodiment of this utility model, the spiral rod spirals through the interior of the connecting plate, and the pressure block is positioned directly above the center of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, this utility model involves hoisting the lifting structure to the center of the truss, then rotating the positive and negative threaded rods to move the two lifting bearing plates towards each other until they can no longer be rotated. The two lifting bearing plates then clamp and fix the truss for hoisting and connection. The support brackets added to both ends of the crossbeam are installed on the connecting plate with nuts. The bottom plate at the lower end of the support bracket can support the truss parts on both sides of the connecting seat. At the same time, by screwing the spiral rod downward, the upper end of the truss is pressed and fixed through the pressure block. This makes the truss stable during hoisting, and the symmetrical structure is not prone to lateral deviation. The hoisting process is safer and more reliable, and it has good practicality.

[0017] The hoisting support plate 5 includes a plate body 501, a sliding block 502, and a guide block 503. The upper end of the plate body 501 is provided with a sliding block 502, and the lower ends of the sliding block 502 are symmetrically provided with guide blocks 503 on both sides. The sliding block 502 is spirally connected to the positive and negative threaded rods 3 and slidably connected to the two limiting rods 4 in the fixed frame 2 on the same side.

[0018] Guide blocks 503, symmetrically arranged at the lower ends of both sides of the sliding block 502, are respectively slidably arranged in the guide grooves 201 symmetrically opened at the upper end of the fixed frame 2 on the same side.

[0019] The support frame 7 includes a base plate 701, uprights 702, threaded posts 703, and nuts 704. The upper surface of the base plate 701 is flush with the upper surface of the bent plate at the bottom of the plate 501. Two uprights 702 are symmetrically fixedly connected to the base plate 701.

The threaded posts 703 at the upper end of the uprights 702 pass through the connecting plate 6 on the same side, and each threaded post 703 is screwed with a nut 704.

[0020] By using the symmetrical support frames 7 at both ends of the aforementioned crossbeam 1 in conjunction with the hoisting clamping connection of the two hoisting bearing plates 5, a three-point connection and fixation of the truss is achieved, which makes the hoisting connection seat and the truss have good stability and improves the safety during the hoisting process.

[0024] The working principle and usage process of this utility model are as follows: In specific use, firstly, by rotating the positive and negative threaded rods 3, the two lifting support plates 5 are moved in opposite directions until they reach the outermost edge. Then, the nut 704 used to fix the support bracket 7 is unscrewed upwards to remove the support bracket 7 from the connecting plate 6. Similarly, the support bracket 7 at the other end is also removed. Then, the structure is placed in the upper center area of ​​the truss, so that the truss is between the two lifting support plates 5. By rotating the positive and negative threaded rods 3, the two lifting support plates 5 are moved towards each other until they can no longer be rotated. The plate 50... 1. The truss is hoisted and clamped, and the bottom end of the truss rests on the bent plate at the bottom end of the plate 501. Then, the truss is hoisted to a certain height by connecting it with the hoisting equipment through two lifting lugs 9. The support brackets 7 at both ends of the cross frame 1 are then reinstalled. The bottom plate 701 of the support bracket 7 supports the two sides of the hoisting point of the two hoisting bearing plates 5. The pressure fixing mechanism 8 at both ends of the cross frame 1 is screwed downward to make the pressure block 803 press against the upper end of the truss, thereby greatly improving the stability of the hoisting connection, making it less prone to lateral deviation, and making the hoisting process of the truss safer and more reliable.
