Technical Field

[0001] The utility model relates to the technical field of steel pipe transportation, and particularly relates to a vertical steel pipe transportation device for narrow spaces. Background Art

[0002] With the acceleration of the urbanization process and the development of high-rise building technology, more and more super high-rise buildings have sprung up. Such buildings usually have a large building area and a high number of floors, and the complexity and installation difficulty of their internal electromechanical systems have also increased accordingly. Especially in areas such as pipe shafts where the space is narrow and the floors are high, the installation of pipes has become a challenging task.

[0003] Existing steel pipe transportation methods include but are not limited to:

[0004] 1. Using manpower to move and hoist steel pipes, this method is inefficient and requires high requirements for workers.

[0005] 2. Cutting the steel pipes into shorter sections and transporting them to the working floors by construction elevators. Although this method is feasible, it adds additional processing steps.

[0006] 3. Using tower cranes to lift the steel pipes to the unloading platforms and then transfer them. This method may cause logistics bottlenecks at busy construction sites.

[0007] All of the above methods not only increase a large amount of labor costs, but also bring potential construction quality and safety hazards due to frequent manual operations. Especially during the construction of super high-rise buildings, these problems are more prominent. Therefore, developing an efficient, safe and steel pipe transportation means applicable to narrow spaces has become a technical problem to be solved urgently. Content of the Utility Model

A pulley is connected to the lower end of the trolley, and a support steel plate is installed at the upper end of the trolley for carrying steel pipes. The upper fixing device is connected with at least three fasteners capable of clamping one end of the steel pipe, and a rope hole is provided in the middle for a steel wire rope to pass through. The lower fixing device is connected with at least three fasteners capable of clamping the other end of the steel pipe, and a buckle is provided in the middle for the steel wire rope to bypass.

[0009] Preferably, the fasteners are a screw rod and a nut that cooperate with each other. At least three radially arranged movable grooves are respectively provided on the upper fixing device and the lower fixing device, and the fasteners are installed in the movable grooves.

[0010] Preferably, a fixed steel plate is provided on the trolley for placing steel pipes. The fixed steel plate is horizontally arranged, and the supporting steel plate is rotatably connected to the trolley. When the supporting steel plate rotates to the horizontal position, it has the same height as the fixed steel plate.

[0011] Preferably, baffles are provided on both sides of the supporting steel plate and the fixed steel plate.

[0012] Preferably, a handle is installed on the side of the lower fixing device facing away from the buckle.

[0013] Preferably, a towing rope is connected to the handle.

[0014] Preferably, a rubber sleeve is sleeved on the screw rod.

[0015] Preferably, a rubber ring is sleeved on the edge of the rope hole.

[0016] Preferably, a rubber pad is laid on the trolley.

[0017] The beneficial effects of the present utility model are as follows:

[0018] Two fixing devices are used in cooperation with the trolley to load steel pipes. The two fixing devices are respectively arranged at both ends of the steel pipes to be transported. One end of the steel wire rope is connected to the lower fixing device, and the whole steel pipe is gradually tilted from the horizontal state to the vertical state and pulled up to the high-rise floor from the narrow transportation space by pulling the steel wire rope through the winch equipment on the high-rise floor.

[0031] Embodiment 1:

[0032] Figures 1-6Shows a vertical transportation device for steel pipes in a narrow space provided by the present utility model, including a trolley 1 for carrying the steel pipe 10 and a supporting upper fixing device 2 and a lower fixing device 3 used in combination. Three fasteners 4 are connected to the upper fixing device 2, and the three fasteners 4 are arranged circumferentially along the center of the upper fixing device 2. During installation, first measure the diameter of the steel pipe 10, and correspondingly configure the positions of the three fasteners 4 according to the diameter so that they can clamp one end of the steel pipe 10. Similarly, three fasteners 4 are also connected to the lower fixing device 3. Similarly, according to the diameter of the steel pipe 10, configure the positions of the three fasteners so that they can clamp the other end of the steel pipe 10. The difference between the upper fixing device 2 and the lower fixing device 3 is that the upper fixing device 2 is used to pass through the steel wire rope 8. Therefore, a rope hole 21 for the steel wire rope 8 to pass through is provided in the middle of the upper fixing device 2. The lower fixing device 3 is used to tie the steel wire rope 8. Therefore, a buckle 31 for the steel wire rope 8 to bypass is provided in the middle of the lower fixing device 3. One end of the steel wire rope 8 passes through the rope hole 21 and is then tied and fixed to the buckle 31. By pulling the other end of the steel wire rope 8 with a mechanical device, the entire steel pipe 10 can be lifted;

[0033] The trolley 1 is used in combination with the upper fixing device 2 and the lower fixing device 3. When the steel wire rope 8 pulls the horizontally placed steel pipe 10 for easy ground transportation, the trolley 1 moves horizontally accordingly. A support steel plate 6 is installed on the trolley 1 to support the steel pipe 10, avoiding direct contact and wear between the steel pipe 10 or the lower fixing device 3 and the ground. A pulley 11 is provided at the lower end of the trolley 1, which can be pulled / pushed. Corresponding tracks can also be set on the ground to cooperate with the pulley 11, enabling the trolley 1 to move along a fixed path, and cooperating with the steel wire rope 8 to pull the steel pipe 10 so that it gradually tilts from a horizontal state until it becomes a vertical state. The vertically placed steel pipe 10 is more likely to pass through a narrow space.

[0034] The fastener 4 is specifically a mutually cooperating screw 41 and nut 42. At least three radially arranged movable slots 5 are respectively provided on the upper fixing device 2 and the lower fixing device 3. The fastener 4 is installed in the movable slot 5. During use, pass the screw 41 through the movable slot 5, and then put the nut 42 on the screw 41 and tighten it to fix the entire fastener 4.

[0035] A fixed steel plate 7 is provided on the trolley 1. The fixed steel plate 7 is horizontally arranged. The support steel plate 6 is rotatably connected to the trolley 1. When the support steel plate 6 rotates to the horizontal position, it has the same height as the fixed steel plate 7. When the steel pipe 10 is in a horizontal state during ground transportation, at this time the support steel plate 6 is horizontally arranged, and the steel pipe 10 is placed on the support steel plate 6 and the fixed steel plate 7. When using the steel wire rope 8 to pull the steel pipe 10, the steel pipe 10 tilts, driving the support steel plate 6 to tilt accordingly. The support steel plate 6 provides a certain supporting force for the steel pipe 10. An inclined plate 13 is also equipped on the trolley 1, which can provide a certain supporting force when the steel pipe 10 tilts.

[0036] On both sides of the support steel plate 6 and the fixing steel plate 7, there are baffles 9 to prevent the steel pipe 10 from rolling left and right and slipping off.

[0037] On the side of the lower fixing device 3 facing away from the buckle, a handle 32 is installed. There is a towing rope 33 on the handle 32. After the steel pipe 10 is pulled up to the designated floor by the steel wire rope 8, the staff manually or uses mechanical equipment to pull the towing rope 33 to guide the steel pipe 10 to be placed at the designated position. A trolley 1 in this embodiment can be equipped on high floors. The support steel plate 6 and the fixing steel plate 7 are also installed on the trolley 1, which can support the steel pipe 10 transported to the designated floor.

[0038] A rubber sleeve 43 is sleeved on the screw rod 41, a rubber ring 22 is sleeved on the edge of the rope hole 21, and a rubber pad 12 is laid on the trolley 1. The rubber material plays a buffering role and can prevent the structures of various metal materials from wearing against each other. Among them, the rubber ring 22 is used to prevent the steel wire rope 8 from wearing and breaking.

[0039] An arc angle 34 is also provided at the edge of the lower fixing device 3 to prevent direct friction loss between the lower fixing device 3 and the trolley 1 when the steel pipe 10 is pulled and tilted by the steel wire rope 8.

[0040] Working principle:

[0041] Before starting the transportation of the steel pipe 10, the staff will first accurately measure the size of the steel pipe 10 to ensure that the subsequent fasteners 4 can fit the diameter of the steel pipe 10. Then, the staff will adjust the positions of the fasteners 4 in the upper fixing device 2 and the lower fixing device 3 so that they can firmly hold both ends of the steel pipe 10. The fastener 4 is composed of a screw rod 41 and a nut 42, and the steel pipe 10 is fixed by adjusting the position of the screw rod 41 in the movable slot 5 and tightening the nut 42.

[0042] Once the positions of the fasteners 4 are adjusted, the staff will place the steel pipe 10 on a special trolley 1. This trolley 1 is equipped with two parallel and equally high steel plates, one for supporting the steel pipe 10 and the other for fixing the steel pipe 10. Then, the staff will install the upper fixing device 2 on the top of the steel pipe 10 and ensure that the steel wire rope 8 can pass through the rope hole 21 on it smoothly; at the same time, install the lower fixing device 3 at the bottom of the steel pipe 10 and fix the other end of the steel wire rope 8 on its buckle 31.

[0043] Subsequently, start the lifting equipment and pull one end of the steel wire rope 8 through a winch or other similar machinery. As the steel wire rope 8 is pulled, the steel pipe 10 starts to slowly tilt from the horizontal state until it finally becomes vertical. During this process, the trolley 1 moves synchronously with the tilt of the steel pipe 10, and the support steel plate 6 also rotates accordingly, always maintaining support for the steel pipe 10 to prevent it from slipping during transportation.

[0044] To further protect the equipment and materials, a rubber ring 22 is installed on the part of the steel wire rope 8 passing through the rope hole 21 to reduce the friction between the steel wire rope 8 and the edge of the rope hole 21, and at the same time avoid damage to the surface of the steel pipe 10. The part of the steel pipe 10 in contact with the trolley 1 is also covered with a rubber pad 12 to reduce the wear between the steel pipe 10 and the trolley 1.

[0045] As the lifting equipment continues to work, the steel pipe 10 is gradually lifted to the designated floor. When the steel pipe 10 reaches the target floor, the staff can precisely guide the steel pipe 10 to the correct position by pulling the towing rope 33 on the lower fixing device 3. At this time, the trolley 1 system on the high floor takes over the work and safely places the steel pipe 10 on the support steel plate 6 of the trolley 1 on this floor, thus completing the entire transportation process of the steel pipe 10.

[0046] In this way, not only the need for manual handling is greatly reduced, the construction efficiency is improved, but also the safety during the construction process is effectively guaranteed.

[0047] The above are only optional embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
