Description

Technical Field

[0001] The utility model relates to the technical field of steel bar lifting safety construction, in particular to a vertical lifting device for steel bars in construction adjacent to an existing line. Background Art

[0002] In existing construction technology, the transportation of vertical steel bars for bridge pier columns is carried out by lifting them with a crane and transferring them to a construction operation platform, and then manually transporting and installing them. This leads to problems such as low installation efficiency, high cost, and high safety risks. Especially during the lifting construction process of pier shaft steel bars near the operating railway line, the steel bars have poor stability during transportation, are prone to tilting, are difficult to transport, and can easily cause devastating damage to the adjacent operating line.

[0003] In order to address the above problems, there is an urgent need for a vertical lifting device for steel bars constructed near existing lines. Utility Model Content

[0004] The purpose of the utility model is to provide a vertical lifting device for steel bars in construction adjacent to an existing line, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, a vertical lifting device for steel bars constructed near an existing line is provided, comprising a loading cylinder, a fixing ring, and a lifting ring. The top of the loading cylinder is open, the lifting ring is fixedly connected to the fixing ring via a first lifting cable, and the fixing ring is fixedly connected to the loading cylinder via a second lifting cable.

[0006] The diameter of the fixing ring is larger than the diameter of the loading cylinder. The loading cylinder and the fixing ring are both provided with lifting holes, and the lifting holes are provided with lifting components.

[0007] The lifting assembly includes a bow-shaped member and a suspension rod. The suspension rod passes through the lifting hole and two ends of the suspension rod are fixedly connected to two ends of the bow-shaped member.

[0008] Furthermore, the fixing ring is provided with two groups of lifting holes, each group having no less than five holes, which are arranged equidistantly in a circular shape, and the two groups of lifting holes are respectively connected to the first sling and the second sling.

[0009] Furthermore, the two groups of lifting assemblies on the fixing ring are fixedly connected by a connecting rod.

[0010] Furthermore, a reinforcing bottom plate is provided at the bottom of the loading cylinder, and the diameter of the reinforcing bottom plate is larger than the diameter of the loading cylinder.

[0011] Furthermore, the inner diameter of the loading cylinder is 220 mm, the height is 600 mm, and the wall thickness is 5 mm; the inner diameter of the fixing ring is 500 mm, the height is 150 mm, and the wall thickness is 10 mm.

[0012] Furthermore, the first sling and the second sling are both made of 16 mm steel wire rope.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. During the lifting process, the steel bars are in an inclined state, and ideally they are evenly oriented in all directions. At this time, the overturning forces generated by the steel bars in all directions can just offset each other, so that there will be no shaking, swinging, or scattering during the lifting process. This solves the safety problem of lifting the pier body steel bars during bridge pier construction and ensures the lifting safety of the construction near the railway operating line.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Those skilled in the art will understand that, unless otherwise stated, the singular forms "a," "an," and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present utility model refers to the presence of the stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0022] See also Figure 1-3As shown, a vertical lifting device for steel bars constructed near an existing line is provided, comprising a loading cylinder 1, a fixing ring 2 and a lifting ring 3. The top of the loading cylinder 1 is open, the lifting ring 3 is fixedly connected to the fixing ring 2 via a first lifting rope 4, and the fixing ring 2 is fixedly connected to the loading cylinder 1 via a second lifting rope 5; Figure 1 It can be seen that in this device, the bottom of the lifting ring 3 is fixedly connected to the five first lifting ropes 4, wherein the other ends of the five first lifting ropes 4 are connected to the fixing ring 2 through the lifting assembly 7, and the fixing ring 2 is fixedly connected to the loading cylinder 1 through the five second lifting ropes 5;

[0023] The diameter of the fixing ring 2 is larger than that of the loading cylinder 1. A lifting hole 6 is formed on both the loading cylinder 1 and the fixing ring 2. A lifting assembly 7 is provided in the lifting hole 6. Here, the inner diameter of the loading cylinder 1 is 220 mm, its height is 600 mm, and its wall thickness is 5 mm. The inner diameter of the fixing ring 2 is 500 mm, its height is 150 mm, and its wall thickness is 10 mm. The first sling 4 and the second sling 5 are both made of 16 mm steel wire rope.

[0024] It is worth noting that the reason why the diameter of the fixing ring 2 is larger than that of the loading tube 1 is that the steel bar can be placed at an angle, so that the contact point between the steel bar and the fixing ring 2 forms a point, the contact point between the steel bar and the loading tube forms a point, and the vertical line of the center of gravity of the steel bar forms another point. The three points can form a triangular structure, which makes the posture of the steel bar more stable during the lifting process and is not prone to shaking, thereby improving the safety of the lifting;

[0025] The lifting assembly 7 includes a bow 701 and a suspension rod 702. The suspension rod 702 passes through the lifting hole 6 and the two ends of the suspension rod 702 are fixedly connected to the two ends of the bow 701.

[0026] like Figure 2 and Figure 3 As shown, the fixing ring 2 is provided with two groups of lifting holes 6, each group having no less than five, and arranged in a circular and equidistant manner. The two groups of lifting holes 6 are respectively connected to the first sling 4 and the second sling 5. The two groups of lifting components 7 of the fixing ring 2 are also fixedly connected by a connecting rod 8;

[0027] like Figure 1 As shown, a reinforcing bottom plate 9 is provided at the bottom of the loading cylinder 1, and the diameter of the reinforcing bottom plate 9 is larger than the diameter of the loading cylinder 1;

[0028] It is worth noting that the diameter of the reinforcing base plate 9 is slightly larger than the diameter of the loading barrel 1. The purpose is to prevent the lifting assembly 7 at the connection between the loading barrel 1 and the second rope 5 from touching the pier wall. Once contact occurs at the barrel mouth of the loading barrel 1 and tilting occurs, it is easy to cause deformation of the steel bars, making the steel bars unusable.

[0029] Specific implementation process:

[0030] Place all components of the device on the ground Figure 1 The steel bars are assembled and connected together in a connection manner, and then the steel bars are passed through the fixing ring 2 and inserted into the loading barrel 1. After all the steel bars are loaded, the lifting ring 5 is connected to the hook of the crane. Finally, the crane transports the steel bars to the inside of the pier body, and then the operator pulls the steel bars out of the loading barrel 1. During the entire transportation process, due to the restrictions of the loading barrel 1 and the fixing ring 2, the steel bars will not swing significantly, fall or scatter.

[0031] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
