Description

Technical Field

[0001] The utility model relates to a transport device, in particular to a telescopic transport joist. Background Art

[0002] Gantry crane is a variation of bridge crane. In ports, it is mainly used for loading and unloading operations of outdoor cargo yards, material yards, and bulk cargo. Its metal structure is like a door-shaped frame, with two legs installed under the load-bearing main beam, which can walk directly on the ground track, and the two ends of the main beam can have outward cantilever beams. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port cargo yards. Gantry cranes are generally transported by large transport ships across the ocean, and the whole machine is transported to the user's terminal for delivery. During this process, the unloader needs to be moved from the terminal to the transport ship, or from the transport ship to the terminal.

[0003] At present, when transporting gantry cranes, a combined transportation method of flatbed transporters and joists is generally used. The flatbed transporter enables the gantry crane to move, while the joists are used to lift and support the gantry crane. Traditional joist structures are mostly fixed, while the size and structure of gantry cranes are diverse, which results in the joist and gantry crane's lifting position or support position will vary, which results in the need to make a variety of different sizes of joists to match, increasing the cost of the enterprise, and the size of the joists used to support the gantry crane is relatively large, which requires a large area to be stored, which is very troublesome.

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] like Figure 1-Figure 6 A telescopic transport joist is shown, comprising

[0025] The joist body is composed of a fixed joist 1 and movable joists 2 connected on both sides of the fixed joist 1. The fixed joist 1 and the movable joist 2 are both solid rectangular structures. There is a gap between the fixed joist 1 and the movable joist 2. The fixed joist 1 and the movable joist 2 are fixed by a connecting component.

[0026] There are two connecting components for connecting the fixed joist 1 and the same movable joist 2, which are respectively located on the upper and lower sides of the fixed joist 1 and the movable joist 2, and are placed in the gap between the fixed joist 1 and the movable joist 2. Figure 3 As can be seen from the schematic diagram shown, the connecting component includes a first connecting ear plate 11, a second connecting ear plate 21 and a connecting pin 4. There are several first connecting ear plates 11, which are arranged in parallel on the side of the fixed joist 1 close to the movable joist 2, and the first connecting ear plates 11 are fixedly connected to the fixed joist 1, and a gap for inserting a single second connecting ear plate 21 is reserved between two adjacent first connecting ear plates 11. There are several second connecting ear plates 21, which are arranged in parallel on the side of the movable joist 2 close to the fixed joist 1, and the second connecting ear plates 21 are fixedly connected to the movable joist 2, and a gap for inserting a single first connecting ear plate 11 is reserved between two adjacent second connecting ear plates 21. The second connecting ear plates 21 are staggered with the first connecting ear plates 11. Connecting holes for horizontally passing the connecting pin 4 are opened on the first connecting ear plates 11 and the second connecting ear plates 21. The connection between the fixed joist 1 and the movable joist 2 is realized by the connecting pin 4 passing through the connecting holes on each of the first connecting ear plates 11 and the second connecting ear plates 21 in turn. The fixing between the fixed joist 1 and the movable joist 2 is achieved by the cooperation of the first connecting ear plate 11, the second connecting ear plate 21 and the connecting pin 4, which facilitates the installation and disassembly between the fixed joist 1 and the movable joist 2 and provides a basis for the subsequent rapid replacement of the movable joist 2.

[0027] When the fixed joist 1 is connected to the movable joist 2, the second connecting ear plates 21 on the movable joist 2 are aligned with the gaps between the first connecting ear plates 11 on the fixed joist 1 and then inserted. The position is adjusted after insertion so that the connecting holes on the second connecting ear plates 21 are aligned with the connecting holes on the first connecting ear plates 11. Then, the connecting pin shaft 4 is used to pass through the connecting holes on the first connecting ear plates 11 and the connecting holes on the second connecting ear plates 21 in turn to achieve the fixation between the fixed joist 1 and the movable joist 2. When the movable joist 2 is disassembled, it is only necessary to pull out the connecting pin shaft 4, which is very convenient.

[0028] The telescopic joist 3 is arranged in the movable joist 2, and the telescopic joist 3 is also in the shape of a rectangular parallelepiped. A slot for inserting the telescopic joist 3 is provided on the side of the movable joist 2 away from the fixed joist 1. Figure 4As shown, the telescopic joist 3 is plugged into the movable joist 2 and can be fixed by welding. The telescopic joist 3 has a horizontally outwardly extending support section 31 on the side away from the movable joist 2. The support section 31 is in the shape of a rectangular parallelepiped, and the size of the support section 31 is smaller than the size of the telescopic joist 3. The support section 31 is connected to the middle position of the telescopic joist 3, so that the telescopic joist 3 and the support section 31 are connected to form a T-shaped structure, and the support section 31 extends out of the movable joist 2, so that the support section 31 is convenient for supporting the equipment. A freely retractable telescopic joist 3 is set in the movable joist 2, and the distance to which the telescopic joist 3 is pulled out can be selected according to actual needs to better support the gantry crane 5 and achieve fine adjustment.

[0029] In order to ensure that the telescopic joist 3 can slide and retract more smoothly, lubricating oil may be applied between the telescopic joist 3 and the movable joist 2 .

[0030] Several parallel support pillows 32 are also arranged on the upper end surface of the support section 31. The support pillows 32 are in the shape of long strips and extend along the long axis of the support beam body. The support pillows 32 are directly placed on the upper end surface of the support section 31 and can be made of wood. The support pillows 32 on the support section 31 are designed to play an isolating role when the support section 3 contacts the gantry crane 5, so as to avoid direct contact and friction between the support section 3 and the gantry crane 5, resulting in wear and tear.

[0031] A reinforcing rib plate 21 is also provided on the outer wall of the movable joist 2. The reinforcing rib plate 21 extends along the edge direction of the outer wall of the movable joist 2. The structural strength of the movable joist 2 is improved by the additional reinforcing rib plate 21, thereby avoiding the reduction of the strength of the movable joist 2 due to the slots provided inside the movable joist 2.

[0032] Reinforcement components are also provided on both sides of the movable joist 2. The reinforcement components are located at the slots of the movable joist 2. There are two reinforcement components located on the same side of the movable joist 2. Figure 5 As shown in the schematic diagram, the reinforcement assembly includes a horizontal reinforcement plate 23 and a diagonal brace plate 24. The horizontal reinforcement plate 23 is a rectangular plate connected to the bottom side of the movable joist 2, and the horizontal reinforcement plate 23 extends horizontally to the outside of the movable joist 2. The bottom side of the diagonal brace plate 24 is connected to the side of the horizontal reinforcement plate 23 away from the movable joist 2, and the upper side of the diagonal brace plate 24 is fixed to the movable joist 2. The design of the reinforcement assembly is also used to strengthen the structural strength of the movable joist 2.

[0033] When the telescopic transport joist of the utility model is used to cooperate with the gantry crane 5, firstly, the corresponding movable joist 2 is selected according to the size of the gantry crane 5 and the position to be supported, and then the movable joist 2 is fixed to the fixed joist 1. After the telescopic joist 3 is pulled out of the movable joist 2 by a certain size, the telescopic joist 3 and the movable joist 2 are fixed by welding, and then the fixed joist 1 and the movable joist 2 are placed on the hydraulic flatbed transport vehicle 6, and the hydraulic flatbed transport vehicle 6 is driven under the gantry crane 5 to lift the gantry crane 5. Figure 6 As shown, the gantry crane 5 is then transported from the inner field to the front of the wharf for loading onto the ship using a hydraulic flatbed transporter 6.
