Technical Field
[0001] The utility model belongs to the field of material lifting, in particular to a concrete chimney material lifting device. Background Art
[0002] The height of a general concrete chimney is 30m to 150m. During the construction process, as the height of the chimney continues to increase, the transportation of steel bars and concrete used in the construction of the concrete chimney becomes increasingly difficult, and the construction cost will increase greatly. From the beginning, a 25t truck crane was used to lift the steel bars, and a pump truck was used to pour the concrete. As the construction height of the concrete chimney increases, the specifications of the lifting machinery continue to increase, and the required length of the pump truck continues to increase, resulting in an increase in the lifting cost. Moreover, when the construction reaches a certain height, the pump truck will not be able to directly pump concrete. Utility Model Content

[0015] The present invention is further described below in conjunction with the accompanying drawings and embodiments:
[0016] In the present invention, the terms "longitudinal", "vertical", "upper", "vertical", "horizontal", "top" and "bottom" indicate the directions or positional relationships based on the attached Figure 1 The orientation or position relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0017] Concrete chimney material lifting device, such as Figure 1 and Figure 2As shown, it includes a winch 1 and a lifting derrick 3. The lifting derrick 3 is arranged in the inner cavity of the concrete chimney 11. The lifting derrick 3 can be built using scaffolding pipes or a rental corridor. The lifting derrick 3 can be only partially arranged along the circumference of the concrete chimney 11, or it can be arranged in the entire circumference. It should be noted that when the lifting derrick 3 is arranged in the entire circumference, a vertically penetrating hollow area is arranged in the center of the lifting derrick 3 as a channel, and the channel serves as a channel for hoisting materials. The channel can be a square area of 1.5m×1.5m, and the specific size is adjusted according to the actual diameter of the concrete chimney. Whether it is a partial circumferential arrangement or a full circumferential arrangement, the lifting derrick 3 needs to be vertically ensured to be 3.5m-4m higher than the concrete chimney, and it is ensured that 2 molds can be cast each time the lifting derrick 3 is raised. The lifting derrick 3 can not only be used for material lifting, but also for concrete chimney construction.
[0018] A hoisting hole 12 penetrating to the inner cavity of the concrete chimney 11 is provided at the bottom of the side wall of the concrete chimney 11; a guide wheel 1 4 is installed on the outer wall of the bottom of the concrete chimney 11; a guide wheel 2 5 is installed on the opposite side of the hoisting hole 12 at the bottom of the lifting derrick 3; a guide wheel 3 6 is provided on the top of the lifting derrick 3; and a center wheel 7 is provided at the center of the top of the lifting derrick 3. The guide wheel 1 4, the guide wheel 2 5, the guide wheel 3 6 and the center wheel 7 can be purchased directly, and a guide wheel with a load capacity of 3t is usually used. The winch 1 is placed outside the concrete chimney 11; the end of the wire rope 2 is pulled out from the winch 1, guided by the guide wheel 1 4, and then passes through the hoisting hole 12, passes through the guide wheel 2 5, extends upward, passes through the guide wheel 3 6, and passes through the center wheel 7. Extends vertically downward.
[0019] The concrete chimney material lifting device disclosed in the utility model, when lifting materials, the materials are attached to the end of the steel wire rope 2, and then the winch 1 works, the steel wire rope 2 is wound on the winch 1, and the materials attached to the end of the steel wire rope 2 rise vertically together with the end of the steel wire rope 2, thereby realizing the lifting of materials. The investment of the concrete chimney material lifting device, first of all, replaces the lifting machinery, greatly reduces the use of large lifting machinery shifts, and thus greatly saves construction costs. Secondly, no matter what height the concrete chimney is constructed to, by adjusting the length of the steel wire rope 2 or the installation height position of the winch 1, the lifting of materials can be realized, which solves the problems of difficulty in material transportation, large waste of machinery shifts, and high construction costs caused by the increase in the construction height of the chimney. Thirdly, the vertical transportation of materials in the concrete chimney is safer and more reliable.
[0020] The steel wire rope 2 passing through the guide wheel 2 5 can be extended obliquely upward to the guide wheel 3 6, that is, the line connecting the guide wheel 3 6 and the guide wheel 2 5 can be at a certain angle to the vertical direction. However, this method will lengthen the steel wire rope 5. In order to avoid the above problem, preferably, the guide wheel 3 6 is located directly above the guide wheel 2 5. In this way, the steel wire rope 2 extends vertically upward from the guide wheel 2 5 to the guide wheel 3 6, and the path is shortened, which can effectively avoid the steel wire rope 2 from The guide wheel 2 5 to the guide wheel 3 6 on the way to interfere with certain components on the lifting derrick 3.
[0021] The wire rope 2 can be passed through the guide wheel 4 from below. In order to better tension the wire rope 2 and allow the wire rope 2 to effectively pass through the lifting hole 12, preferably, the guide wheel 4 is lifted from below the wire rope 2 and guides the wire rope 2.
[0022] During hoisting, materials such as steel bars or concrete are suspended at the end of the steel wire rope 2 and rise with the end of the steel wire rope 2. In order to prevent the materials from rushing to the top during hoisting, preferably, a limiting device 8 is provided directly below the center wheel 7, and the limiting device 8 is installed on the lifting derrick 3. During hoisting, the materials first contact the limiting device 8 during the rising process, and are blocked by the limiting device 8, which plays a limiting role, preventing the materials from rushing to the top of the lifting derrick 3, and ensuring safety.
[0023] The limiting device 8 can be installed on the side wall of the lifting derrick 3. However, when the limiting device 8 is installed on the side wall of the lifting derrick 3, the connection between the limiting device 8 and the lifting derrick 3 will be subject to shearing, and the force is complicated. In order to simplify the force, in this embodiment, the limiting device 8 is suspended at the top of the lifting derrick 3. The limiting device 8 is installed at the top of the lifting derrick 3. During the material hoisting process, it mainly bears the upward impact of the material, and the force form is simpler.
[0024] The stopper block can be suspended by a suspension rod as the limiting device 8. In this embodiment, Figure 3 As shown, the limiting device 8 includes a limiting baffle 9, and the limiting baffle 9 is suspended at the top of the lifting derrick 3 through a retractable elastic connector 10. The limiting baffle 9 is in direct contact with the material and plays a role in blocking the material. The elastic connector 10 is mainly used to connect the limiting baffle 9 to the top of the lifting derrick 3. The elastic connector 10 can be retracted, that is, under the upward force, the elastic connector 10 can be deformed to shorten the distance between the limiting baffle 9 and the top of the lifting derrick 3; when the upward force disappears, the elastic connector 10 can automatically restore the deformation and the limiting baffle 9 is reset. The elastic connector 10 can be a telescopic spring or a suspension rope. The retractable elastic connector 10 suspends the limiting baffle 9 at the top of the lifting derrick 3, and plays a buffering role at the moment when the material impacts the limiting baffle 9.
[0025] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
