Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a scaffolding steel pipe hoisting device. Background Art

[0002] In construction projects, a large number of steel pipe racks are needed for structural construction. The length of steel pipe materials ranges from 1m to 6m. Conventional hoisting uses steel wire ropes to hoist the whole bundle, which is quite dangerous. Since the steel pipe rack is hoisted horizontally, in order to facilitate the hoisting of steel pipes during the construction of the basement structure, it is necessary to reserve a larger hoisting hole on the structural plate, which is inconvenient to seal later.

[0003] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0004] In order to overcome the defects of the prior art, a scaffolding steel pipe lifting device is now provided to solve the problem that when the existing steel pipe frame materials are horizontally lifted in and out of the basement structure by steel wire ropes, it is necessary to reserve a larger lifting hole on the basement structure plate.

[0005] In order to achieve the above-mentioned purpose, a scaffold steel pipe hoisting device is provided, comprising:

[0006] A bearing tube is inserted into the lower end of the steel pipe, and a first lifting lug is installed at the tube mouth of the bearing tube;

[0007] Two connecting plates, one end of each of which is detachably mounted on opposite sides of the tube opening of the carrying tube;

[0008] A limit frame for sleeve-mounting the upper end of the steel pipe is installed between the two connecting plates in an adjustable manner, and the limit frame is coaxially arranged with the bearing tube.

[0009] Furthermore, two limiting ridges are formed on opposite sides of the limiting frame respectively, a sliding groove is formed between the two limiting ridges on one side of the limiting frame, and the connecting plate is slidably arranged in the sliding groove.

[0010] Furthermore, the connecting plate is provided with a plurality of locking holes, and the plurality of locking holes are arranged at intervals along the length direction of the connecting plate. A locking tongue is elastically installed in the sliding groove, and one end of the locking tongue extends into a locking hole.

[0011] Furthermore, the two limiting protrusions extend oppositely on one side away from the limiting frame to form anti-slip flanges, and the anti-slip flanges abut against the side of the connecting plate away from the limiting frame.

[0012] Furthermore, a second lifting ear is installed at a frame opening of the limiting frame away from the supporting tube.

[0013] Furthermore, the diameter of the supporting tube is matched with the diameter of the limiting frame.

[0014] The beneficial effect of the utility model is that the scaffold steel pipe hoisting device of the utility model can hoist steel pipes of different lengths. During hoisting, the distance between the limit frame and the bearing tube can be adjusted according to the length of the hoisted steel pipe. When hoisting a short steel pipe, the bearing tube is directly used for hoisting. When hoisting a long steel pipe, the bearing tube and the limit frame can be connected with a connecting plate and then hoisted. By adjusting the different positions of the lock hole of the connecting plate, it is possible to hoist steel pipes of different lengths. During the hoisting process, the hoisting center of gravity is at the lower part of the first lifting ear, so the steel pipe is hoisted in a vertical manner, which can reduce the size of the hoisting hole reserved on the basement structure plate and improve the stability of the hoisting.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Reference Figures 1 to 3 As shown, the utility model provides a scaffold steel pipe hoisting device, comprising: a bearing tube 1, a connecting plate 2, and a limiting frame 3.

[0022] In this embodiment, the bearing tube is in the shape of a cuboid, the limiting frame is in the shape of a rectangle, the diameter of the bearing tube 1 is adapted to the diameter of the limiting frame 3, and the outer diameter of the bearing tube is adapted to the outer diameter of the limiting frame.

[0023] The bearing tube and the limiting frame are coaxially arranged.

[0024] The bearing tube 1 is used for inserting the lower end of the steel pipe 4. The limiting frame 3 is used for sleeve-mounting the upper end of the steel pipe 4.

[0025] A first lifting lug 11 is installed at the mouth of the supporting tube 1 .

[0026] There are two connecting plates 2 . One end of the two connecting plates 2 is detachably mounted on opposite sides of the tube opening of the carrying tube 1 .

[0027] The position limiting frame 3 is adjustable between the two connecting plates 2. The position limiting frame 3 is coaxially arranged with the bearing tube 1. The position of the position limiting frame can be adjusted along the length direction of the connecting plates.

[0028] When the limit frame is close to the bearing tube, Figure 1 As shown, a short steel pipe is loaded in the bearing tube and is arranged vertically.

[0029] When the limiting frame is away from the bearing tube, the long steel tube can be rotated in the bearing tube. At this time, the lower end of the long steel tube is inserted in the bearing tube, and the upper end of the long steel tube is inserted in the limiting frame.

[0030] The utility model of the scaffold steel pipe hoisting device can hoist steel pipes of different lengths. During hoisting, the distance between the limit frame and the bearing tube can be adjusted according to the length of the hoisted steel pipe. When hoisting a short steel pipe, the bearing tube is directly used for hoisting. When hoisting a long steel pipe, the bearing tube and the limit frame can be connected with a connecting plate and then hoisted. By adjusting the different positions of the lock hole of the connecting plate, it is possible to hoist steel pipes of different lengths. During the hoisting process, the hoisting center of gravity is at the lower part of the first lifting ear, so the steel pipe is hoisted in a vertical manner, which can reduce the size of the hoisting hole reserved on the basement structure plate and improve the stability of the hoisting.

[0031] As a preferred embodiment, two limiting convex ridges 32 are respectively formed on opposite sides of the limiting frame 3. A slide groove is formed between the two limiting convex ridges 32 on one side of the limiting frame 3. The connecting plate 2 is slidably arranged in the slide groove.

[0032] In this embodiment, the connecting plate 2 is provided with a plurality of locking holes 20. The plurality of locking holes 20 are arranged at intervals along the length direction of the connecting plate 2. A locking tongue 34 is elastically installed in the slide groove. One end of the locking tongue 34 extends into one of the locking holes 20.

[0033] See also Figure 1As shown, the two limiting convex ridges 32 extend oppositely on one side away from the limiting frame 3 to form anti-slip flanges 33. The anti-slip flanges 33 abut against the side of the connecting plate 2 away from the limiting frame 3.

[0034] Continue reading Figure 1 As shown, a second lifting ear 31 is installed at a frame opening of the limiting frame 3 away from the carrying tube 1 .

[0035] In this embodiment, a receiving hole is provided on the outer side of the side of the limiting frame. One end of the locking tongue is elastically installed in the receiving hole by a spring, and when the limiting frame is moved to align the receiving hole with a locking hole, the other end of the locking tongue extends into the locking hole, thereby locking the limiting frame on the connecting plate.

[0036] When the limiting frame needs to be moved, the locking tongue is pressed and retracted into the accommodating hole, and the limiting frame can be moved to select a locking hole at a suitable position.

[0037] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
