Description

Technical Field

[0001] The present application relates to the field of wire saws, and particularly to a precast concrete column and a stone wire saw dedicated to a lifting stone wire saw. Background Art

[0002] In related technologies, a lifting stone wire saw includes a column, a cutting assembly fixedly installed on the column, and a lifting platform for driving the stone to move up and down. The columns of existing lifting stone wire saws usually include two types: metal columns and concrete columns. Metal columns have high strength, but high cost, large weight, inconvenient transportation, and are susceptible to corrosion. Concrete has a lower manufacturing cost and is not easily decayed, and can be used for a long time under proper maintenance. However, concrete columns have lower strength, are inconvenient to manufacture, and the track cannot be pre-installed above the concrete, resulting in high installation difficulty and long installation time. There is currently no column that can combine the advantages of both. Summary of the Invention

[0003] In view of this, the present application provides a precast concrete column and a stone wire saw dedicated to a lifting stone wire saw, which has high strength, is convenient to install, has a long service life and low cost.

[0004] To achieve the above object, the present application is realized through the following technical solutions:

[0005] A precast concrete column dedicated to a lifting stone wire saw, characterized in that: it includes a steel shell, reinforcing ribs fixedly arranged inside the steel shell, and a concrete layer filled inside the steel shell. A guide rail surface for installing a guide rail is formed on the steel shell, and at least one vertically penetrating pouring hole is reserved inside the concrete layer.

[0006] For the above precast concrete column dedicated to a lifting stone wire saw in the present application, the column combines a steel shell with the internal concrete layer, and can simultaneously combine the advantages of steel columns and concrete columns. The internal reinforcing ribs play a role in strengthening the structure. Moreover, compared with a concrete column, the steel shell can more conveniently process a guide rail surface. And pouring holes are reserved inside the concrete layer, and the bottom base can be connected by secondary pouring of cement into the pouring holes, thereby increasing the strength.

[0007] The manufacturing process of the column is to first weld the outer shell, and then precast concrete. After the concrete dries, the concrete column already has a certain strength and can bear the processing load and the load of the machine platform installed on it. Then, the guide rail surface is processed, and then the entire equipment is installed. After the installation is completed, the reserved space is finally poured again to connect with the ground. If only a steel outer shell is welded, it has no strength and cannot support the installation components on the upper layer of the wire saw. The iron plate is also very thin and the wire rail surface cannot be directly processed, which is prone to deformation. Only after pouring a layer of concrete and the inside becomes basically solid and has a certain strength can the track surface be processed and the upper installation load be borne.

[0008] The present application also provides a lifting type stone wire saw, which has a special precast concrete column for the lifting type stone wire saw as described above, and is characterized in that: it further includes a cutting assembly fixedly installed on the four columns and a lifting assembly connected to the four columns; the lifting assembly includes a lifting table, guide rails, lifting lead screws and a lifting motor. The four guide rails are respectively fixedly installed on the four columns, the lifting table is slidably connected to the four guide rails, the four lifting lead screws are respectively fixedly installed on the four columns and connected to the four corners of the lifting table, and the lifting motor is used to drive the lifting lead screws to rotate, so as to drive the lifting table to move up and down. Among them, the four lead screws are connected to the four corners of the lifting, so the stability is better.

[0009] In some embodiments, the cutting assembly includes a cutting frame installed on the four columns, four main wheels rotatably connected to the cutting frame for winding the cutting wire, a driving motor for driving the main wheels to rotate, and two wire winding and unwinding systems installed on the cutting frame for respectively controlling the winding and unwinding of the cutting wire; the wire winding and unwinding system includes a wire winding and unwinding wheel for winding and unwinding the wire, a wire arranging wheel that can move and adjust along the axial direction of the wire winding and unwinding wheel, a swingable tension wheel, and an inlet and outlet wire wheel for adjusting the inlet and outlet direction of the cutting wire. Among them, a water-proof cover is further covered on the outer periphery of the inlet and outlet wire wheel.

[0010] When the cutting wire cuts the stone, it needs to be cooled by a spraying system. Since the wire winding and unwinding wheel is the closest to the main wheel, the wire winding and unwinding system is easy to operate during the wire winding and unwinding process. A water-proof cover is arranged on the outer periphery of the inlet and outlet wire wheel, which can reduce the entry of water vapor.

[0011] It can be seen from the above technical solutions that the present application has at least the following advantages and positive effects:

[0012] A special precast concrete column for a lifting stone wire saw in the present application. The column combines a steel shell with an internal concrete layer, which can simultaneously possess the advantages of both steel columns and concrete columns. Among them, the internal reinforcing bars play a role in strengthening the structure. Moreover, compared with concrete columns, the steel shell can be more conveniently processed into a guide rail surface. And pouring holes are reserved inside the concrete layer, and the column can be connected to the bottom base by secondary pouring of cement into the pouring holes, thereby increasing the strength.

[0018] In order to make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, rather than aiming to limit the present application.

[0019] Refer to Figures 1 to 3 , an embodiment of the present application provides a special precast concrete column for a lifting stone wire saw, including a steel shell 11, reinforcing bars 12 fixedly arranged inside the steel shell 11, and a concrete layer 13 filled and arranged inside the steel shell 11. A guide rail surface 14 for installing a guide rail 22 is formed on the steel shell 11, and at least one vertically penetrating pouring hole 15 is reserved inside the concrete layer 13.

[0020] The special precast concrete column for the lifting stone wire saw. The column 1 combines a steel shell 11 with an internal concrete layer 13, which can have the advantages of both steel columns and concrete columns at the same time. The internal reinforcing bars 12 play a role in strengthening the structure. Moreover, the steel shell 11 can be more conveniently processed into a guide rail surface 14 compared with a concrete column. And a pouring hole 15 is reserved inside the concrete layer 13, and the column can be connected to the bottom base 4 by secondary pouring of cement into the pouring hole 15, thereby increasing the strength.

[0021] The manufacturing process of the special precast concrete column for the lifting stone wire saw is as follows:

[0022] Manufacture the steel shell 11; pour the concrete layer 13; process the guide rail surface 14; connect the column 1 to the machine table by secondary pouring of cement through the pouring hole 15.

[0023] The purpose of the secondary pouring of the column is that a cutting component and a lifting component are loaded on the column. It is necessary to first pour the concrete layer 13 to increase the strength, otherwise the column is prone to deformation, and finally it is connected to the machine table as a whole through secondary pouring.

[0024] Figures 3 to 4 , which shows another embodiment of the present application. A lifting stone wire saw has the above-mentioned special precast concrete column 1 for the lifting stone wire saw, and further includes a cutting component 3 fixedly installed on the four columns 1 and a lifting component 2 connected to the four columns 1; the lifting component 2 includes a lifting table 21, guide rails 22, lifting lead screws 23 and a lifting motor. The four guide rails 22 are respectively fixedly installed on the four columns 1. The lifting table 21 is slidably connected to the four guide rails 22. The four lifting lead screws 23 are respectively fixedly installed on the four columns 1 and connected to the four corners of the lifting table 21. The lifting motor is used to drive the lifting lead screws 23 to rotate, thereby driving the lifting table 21 to move up and down. Among them, the four lead screws are connected to the four corners of the lifting, so the stability is better.

[0025] The cutting component 3 includes a cutting frame 31 installed on the four columns 1, four main guide wheels 32 rotatably connected to the cutting frame 31 for winding the cutting wire 36, a driving motor 33 for driving the main guide wheels 32 to rotate, and two sets of wire winding and unwinding systems 34 installed on the cutting frame 31 for respectively controlling the winding and unwinding of the cutting wire 36; the wire winding and unwinding system 34 includes a wire winding and unwinding wheel 341 for wire winding and unwinding, a wire arranging wheel 342 that can move and adjust along the axial direction of the wire winding and unwinding wheel 341, a swingable tension wheel 343, and an inlet and outlet wire wheel 344 for adjusting the inlet and outlet directions of the cutting wire 36. A water-proof cover 35 is also covered on the outer periphery of the inlet and outlet wire wheel 344.

[0026] When the cutting wire 36 cuts the stone 5, it needs to be cooled by the spraying system. Since the wire winding and unwinding wheel 341 is the closest to the main guide wheel 32, the wire winding and unwinding system 34 is easy to operate during the wire winding and unwinding process. A water-proof cover 35 is provided on the outer periphery of the wire inlet and outlet wheel 344, which can reduce the entry of water vapor.

[0027] The working process and usage method of the lifting type stone wire saw in the above embodiment will be briefly described as follows:

[0028] See Figures 3 - 4 , the stone 5 is placed on the lifting table 21, and the lifting table 21 is continuously moved upward by the lifting screw rod. The cutting wire 36 spirally winds back and forth on the four main guide wheels 32 after coming out of the wire winding and unwinding system 34 and is connected to the wire winding and unwinding system 34 at the other end. The driving motor 33 drives the main guide wheels 32 to rotate forward and backward. In this way, the cutting wire 36 between the two lower main guide wheels 32 forms a cutting mesh surface, which can reciprocate to saw the stone 5. The wire winding and unwinding system 34 at one end continuously releases new wire, and the wire winding and unwinding system 34 at the other end continuously collects the old wire after cutting. Until the stone 5 is cut to the bottom, the lifting table 21 resets downward.

[0029] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, and are not intended to limit them; although the embodiments of the present application have been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
