Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a tower crane hopper and a use method thereof. Background Art

[0002] During the construction of the construction site structure, the traditional tower crane hopper is a frame hopper, which is inconvenient for workers to unload and takes too long. In addition, different hoppers need to be frequently replaced for different hoisting objects. Therefore, how to provide a tower crane hopper that is easy to install, safe and economical is a technical problem that technicians in this field need to solve urgently. There are many types of tower crane hoppers on the construction site, and the tower crane hoppers need to be frequently replaced when hoisting different types of materials. Summary of the invention

[0003] In view of the problem that there are many types of tower crane buckets on construction sites and that the tower crane buckets need to be frequently replaced when hoisting different types of materials, the present invention provides a tower crane bucket and a method of use, which can hoist large and small blocks, long and short wooden blocks, formwork, earth, sand and gravel, waterproof membranes and other materials on the basis of fully meeting the hoisting safety requirements, and has excellent economic effects, simple technical processes, strong operability for workers, and is extremely practical on site.

[0004] In order to solve the above technical problems, the present invention includes the following technical solutions:

[0005] A tower crane hopper, comprising:

[0006] An inverted right-angled trapezoidal hopper body, the front end of the hopper body is an arc surface, the bottom plate of the hopper body is an open fan, the front end is connected to the bottom plate by a rotating shaft, a pair of first steel wire rope hooks are provided at the upper mouth of the hopper body directly above the rotating shaft, a pair of second steel wire rope hooks are provided on the upper side of the back plate of the hopper body, a pair of third steel wire rope hooks are provided on the lower side of the back plate, and a pair of fourth steel wire rope hooks are provided at one end of the bottom plate away from the arc surface of the front end.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] (1) The tower crane hopper of the present invention comprises an inverted right-angle trapezoidal hopper body and four pairs of wire rope hooks arranged in coordination. The front end of the hopper body is an arc surface, the bottom plate of the hopper body is an open fan, the front end is connected to the bottom plate through a rotating shaft, a pair of first wire rope hooks are arranged at the upper opening of the hopper body just above the rotating shaft, a pair of second wire rope hooks are arranged on the upper side of the back plate of the hopper body, a pair of third wire rope hooks are arranged on the lower side of the back plate, and a pair of fourth wire rope hooks are arranged at one end of the bottom plate away from the front end arc surface. When lifting, the first wire rope hook, the second wire rope hook and the fourth wire rope hook are started at the same time; when unloading, the A type of unloading method, the B type of unloading method or the combination of the A type of unloading method and the B type of unloading method can be selected according to the actual material volume and shape. Among them, the A type of unloading method includes: loosening the first wire rope hook, completing the material unloading from the arc surface, thereby realizing the single-side dumping type unloading. This unloading method makes the force of the entire hopper balanced, which can increase the service life of the hopper body. In addition, the unloading process is relatively smooth, which reduces the damage to the finished product of the material and also improves the safety factor of the lifting. Type B unloading method includes: loosening the fourth wire rope hook, lifting the first wire rope hook, the second wire rope hook and the third wire rope hook at the same time, completing the material unloading work from the bottom plate, thereby realizing unloading at the bottom of the hopper. This unloading method can unload quickly and can ensure unloading without residue.

[0009] (2) The tower crane hopper of the present invention has a simple structure, low labor and material input, simple manufacture, convenient operation, and can effectively utilize construction site materials such as scrap steel plates, angle steels, channel steels, square tubes, etc., with unlimited turnover, and can hoist any solid materials on the construction site, and the loading and unloading are simple, which can effectively reduce labor. Moreover, it can overcome the defects of conventional tower crane hoppers such as long unloading time, and has a promoting effect on the safety, quality and progress control of engineering projects, and a small hopper can play a big role.

[0010] (3) The method for using the tower crane bucket of the present invention has simple process, is easy for workers to use, has a high safety factor, is very practical in tower crane hoisting, and has excellent economic and social effects. It has low installation difficulty, good economic effect, high safety factor, stable maintenance performance, and has good promotion value.

[0011] Furthermore, in order to facilitate material acquisition and save costs, the arc surface of the front end is made of an arc steel plate with a thickness of 4 mm.

[0012] Furthermore, in order to improve the stress strength of the lifting point and increase the safety of lifting, a pad is provided at the connection between each wire rope hook and the hopper body.

[0013] Furthermore, the hopper body frame is formed by splicing and fixing angle steel, channel steel, square tube and steel plate, so that only inexpensive common construction components are needed, which has low cost and good effect.

[0014] Furthermore, considering that the bottom plate of the hopper body is an open window, the bottom plate of the hopper is kept in a closed state by lifting with the fourth wire rope hook during lifting. When unloading from the lower mouth of the hopper body, the fourth wire rope hook is released. In order to achieve the above-mentioned functions, the bottom plate of the hopper body is connected to the arc surface of the front end through a rotating shaft, and the rotating shaft is made of steel pipe, thereby saving costs and facilitating installation.

[0015] The present invention also provides a method for using a tower crane hopper, which comprises the following steps:

[0016] Step 1, providing the aforementioned tower crane hopper for standby;

[0017] Step 2, fully loading the tower crane hopper with materials;

[0018] Step 3: hoist the first wire rope hook, the second wire rope hook and the fourth wire rope hook at the same time, and hoist the tower crane hopper fully loaded with materials in step 2 to the construction work surface;

[0019] Step 4: Release the first wire rope hook and complete the material unloading work from the arc surface of the front end.

[0020] Furthermore, since the front end of the hopper body is an arc surface, it can buffer the material during unloading, and compared with conventional hoppers, it can reduce the damage to the material caused by unloading, thereby ensuring the quality of the material. At the same time, considering that this one-sided dumping method may cause unloading residue, the material described here is a long or cylindrical material.

[0021] Furthermore, the material includes blocks, coils, wood or steel pipes.

[0022] The present invention also provides a method for using a tower crane hopper, comprising the following steps:

[0023] Step 1, providing the aforementioned tower crane hopper for standby;

[0024] Step 2, fully loading the tower crane hopper with materials;

[0025] Step 3: hoist the first wire rope hook, the second wire rope hook and the fourth wire rope hook at the same time, and hoist the tower crane hopper fully loaded with materials in step 2 to the construction work surface;

[0026] Step 4: loosen the fourth wire rope hook, and simultaneously lift the first wire rope hook, the second wire rope hook and the third wire rope hook to complete the material unloading work from the bottom plate.

[0027] Furthermore, in order to ensure that there is no residue when unloading, the fourth wire rope hook arranged at the end of the bottom plate away from the rotating shaft is loosened, and the material can be unloaded through the lower opening of the hopper. The material is granular or small in size. BRIEF DESCRIPTION OF THE DRAWINGS
