[0002] At present, most of the automated masonry operations for columnar structures such as blast furnaces and ladles using automatic masonry equipment are fixed-point operations, that is, the frame of the automatic masonry equipment is fixedly set on the masonry area of ​​a single structure, and the masonry platform is set on the frame column for operation. After the masonry of a single structure is completed, the automatic masonry equipment is disassembled and transferred to the next structure. This operation method will take a lot of time in the equipment disassembly and transfer process. Therefore, we are currently focusing on developing automatic masonry equipment that can perform fast mobile operations on groups of structures. Based on this demand, a gantry frame that walks on the ground rail is currently used as the basic solution for overall transfer. However, it is still necessary to develop a connection solution in which the columns can be raised and lowered relative to the frame, so as to meet the demand for transferring the operation area without disassembling the entire machine, thereby saving equipment transfer time; in addition, when a movable gantry frame structure is used for movable operation equipment, the stability problem during the masonry construction process is also a key factor that needs to be considered.

The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0023] Please also read Figure 1 and Figure 2 The lifting column provided by the utility model is now described. The lifting column comprises a mounting seat 10, a column body 20, and a driving assembly 30; wherein the mounting seat 10 is used to be fixedly connected to the middle part of the walking gantry frame 40; the column body 20 vertically passes through the mounting seat 10 and cooperates with the mounting seat 10 to slide up and down, and the column body 20 has a supporting state in which the bottom end is supported on the bottom surface of the structure by sliding downward, and also has a suspended state in which the bottom end is higher than the top surface of the structure by sliding upward; the driving assembly 30 is arranged on the walking gantry frame 40 or the mounting seat 10, and the output end of the driving assembly 30 is connected to the column body 20, and is used to drive the column body 20 to slide up and down.

[0024] It should be noted that the walking gantry frame 40 can specifically be a gantry frame that travels on two parallel heavy rails on both sides of the masonry area, and its main function is to drive the column body 20 and the masonry platform arranged on the column body 20 to travel in different masonry areas; it should be explained that in this embodiment, the column body 20 serves as the installation basis of the masonry platform, and the connection method between it and the masonry platform can specifically be the same as the connection method between the masonry platform and its fixed column in conventional fixed-point operation equipment, which will not be described in detail here.

[0025] In this embodiment, the driving component 30 can specifically be a structure in which a gear rack pair is used to drive the column body 20 to move up and down relative to the walking gantry frame 40, or it can be a structure in which a winch 31 is used to pull the column body 20 up and down. Considering the movement space requirement of the masonry platform on the column body 20, it is preferred to use a winch 31 to drive the column body 20 to move up and down, thereby saving space.

[0026] The working mode of the lifting column provided in this embodiment is as follows: during normal masonry operations, the column body 20 descends and is supported on the bottom surface of the structure (specifically, it can be the bottom wall of a structure with a bottom, or it can be the foundation of a structure without a bottom), so that the self-gravity of the column body 20 and the load of the masonry platform are all transferred to the bottom surface of the structure, avoiding shaking or deformation due to excessive load on the walking gantry bracket, thereby ensuring the stability of the masonry operation; when it is necessary to transfer the operating area, the driving assembly 30 drives the column body 20 and the masonry platform arranged on the column body 20 to rise together to form a suspended state, until the bottom end of the column body 20 is higher than the top surface of the structure (the masonry operation process is a circumferential closed-loop masonry, so the entire machine needs to be higher than the structure to move smoothly), and then the walking gantry frame 40 is started to move toward the target position. After moving to the target position, the driving assembly 30 drives the column body 20 to descend to the supporting state again, and the entire transfer process does not require disassembly of equipment.

[0027] On the basis of the above, in order to improve the stability of the suspended state of the column body 20 and the safety of the equipment transfer process, a fall arrester is arranged between the column body 20 and the mounting seat 10. The fall arrester is used to stop the column body 20 on the mounting seat 10 when the falling speed of the column body 20 exceeds a threshold.

[0028] Compared with the prior art, the lifting column provided in the present embodiment can utilize the driving assembly 30 to drive the column body 20 and the masonry platform arranged on the column body 20 to rise together until the bottom end of the column body 20 is higher than the top surface of the structure when the working area needs to be transferred. Then the walking gantry frame 40 can be directly transferred to the target position. After the transfer is in place, the driving assembly 30 drives the column body 20 to descend to form a supporting state, thereby realizing the overall transfer of the equipment without disassembly, which can save the equipment disassembly and reassembly time during the equipment transfer process, thereby improving the equipment transfer efficiency; in addition, based on the supporting state of the column body 20, the load of the walking gantry frame 40 during the masonry construction process can be reduced, thereby improving the construction stability.

[0029] In some embodiments, see Figure 2 The mounting seat 10 includes a top seat 11 and a base 12. The top seat 11 is fixedly connected to the top of the beam of the walking gantry frame 40, and the base 12 is fixedly connected to the bottom of the beam of the walking gantry frame 40. Both the top seat 11 and the base 12 are slidably sleeved on the column body 20. The top seat 11 and the base 12 fixed to the middle of the beam of the walking gantry frame 40 with upper and lower intervals can form a sliding fit with the column body 20 respectively, thereby improving the radial restraint force on the column body 20, thereby preventing the column body 20 from tilting or shaking, and improving the stability of the column body 20 moving up and down relative to the walking gantry frame 40 driven by the driving assembly 30.

[0030] For some possible implementations, see Figure 2 A plurality of groups of first rolling members 111 are provided on the top seat 11, and each group of first rolling members 111 corresponds to the surrounding side walls of the rolling column body 20; a plurality of groups of second rolling members 121 are provided on the base 12, and each group of second rolling members 121 corresponds one by one to each group of first rolling members 111, and each group of second rolling members 121 corresponds to the surrounding side walls of the rolling column body 20.

[0031] The first rolling member 111 and the second rolling member 121 are used to roll and support the side walls of the column body 20. Compared with the conventional sliding matching method, no sliding gap is required. This not only improves the stability of the up and down movement of the column body 20, but also makes the rolling contact smoother and lighter than the sliding contact. It also avoids the column body 20 and the top seat 11 and / or the base 12 from getting stuck.

[0032] Specifically, in this embodiment, the first rolling member 111 and the second rolling member 121 have the same structure, wherein, see Figure 3 The first rolling member 111 includes a connecting frame 1111, a first roller 1112 and a second roller 1113; the connecting frame 1111 is fixedly connected to the top seat 11; the first roller 1112 is arranged on the connecting frame 1111; the second roller 1113 is arranged on the connecting frame 1111, and the axial direction of the second roller 1113 is perpendicular to the axial direction of the first roller 1112; wherein the first roller 1112 and the second roller 1113 are respectively rolled on two adjacent side walls of the column body 20.

[0033] It should be explained that in this embodiment, the column body 20 adopts a square or rectangular cross-sectional structure, and the above-mentioned first rolling member 111 and the second rolling member 121 are both arranged corresponding to the corner positions of the column body 20, and the first roller 1112 and the second roller 1113 arranged perpendicular to each other are respectively rolled on the wall surfaces on both sides of the same corner of the column body 20. On this basis, a first rolling member 111 can be respectively arranged on the top seat 11 corresponding to the four corners of the column body 20, thereby forming a mode in which four first rolling members 111 embrace the column body 20, which can improve the connection reliability and stability between the column body 20 and the top seat 11 and the base 12.

[0034] As a specific implementation of the above-mentioned drive assembly 30, please refer to Figure 1 The driving assembly 30 includes a winch 31, a guide wheel 32 and a wire rope 33; wherein the winch 31 is fixedly connected to the walking gantry frame 40; the guide wheel 32 is rotatably connected to the mounting seat 10; one end of the wire rope 33 is wound around the drum 311 of the winch 31, and the other end bypasses the guide wheel 32 and extends downward, and the extended end is connected to the bottom end of the column body 20.

[0035] The winch 31 can be set at the end of the beam of the walking gantry frame 40 to reduce the load in the middle of the beam. The guide wheel 32 is used to bend the wire rope 33 downward at a position close to the column body 20, so that the wire rope 33 can be connected to the bottom end of the column body 20 at a vertical or nearly vertical angle, thereby reducing the force on the column body 20 in the non-vertical direction and improving the stability of the lifting and lowering movement of the column body 20 under the traction of the wire rope 33.

[0036] In order to improve the driving stability, such as Figure 1 As shown, the hoist 31 has two drums 311, each drum 311 is wound with a wire rope 33, and the mounting seat 10 is provided with two guide wheels 32 respectively suitable for the two wire ropes 33 to pass around. A single wire rope 33 cannot ensure the overall force balance of the column body 20, so here the column body 20 is pulled by connecting two drums 311 to the two wire ropes 33, and the two wire ropes 33 can be pulled on both sides of the bottom of the column body 20 respectively. Since the two drums 311 are driven by the same hoist 31, the pulling force of the two wire ropes 33 can be guaranteed to be consistent, thereby ensuring the force balance of the column body 20. Compared with the pulling method of a single wire rope 33, it is not only more stable, but also the two wire ropes 33 have strong bearing capacity, avoiding the accident of the wire rope 33 breaking and causing the column body 20 to fall.

[0037] It should be noted that see Figure 1 and Figure 4 In this embodiment, two lifting ears 21 are provided at the bottom end of the column body 20, and the two lifting ears 21 are respectively aligned with the two guide wheels 32 in the vertical direction, and the two steel wires 33 are respectively fixedly connected to the two lifting ears 21. By setting the lifting ears 21 to correspond to the two guide wheels 32, the vertical state of the two steel wires 33 can be ensured, so that the overall traction force on the column body 20 is in the vertical direction, which can reduce the traction force deviating from the axial direction of the column body 20 and affecting the smoothness of the movement of the column body 20.

[0038] For some possible implementations, see Figure 4 A ball joint seat 22 is provided at the bottom of the column body 20, and the ball joint seat 22 is used to support the bottom surface of the structure. Since the bottom surface of the structure may not be a horizontal surface, such as the substrate of a ladle is usually a spherical surface, in this case, the ball joint seat 22 on the bottom wall of the column body 20 is used to support the bottom surface of the structure, which can ensure that the ball joint seat 22 is in stable contact with the bottom surface of the structure, and at the same time ensure that the column body 20 can remain vertical, thereby improving the stability of the support state of the column body 20.

[0039] On this basis, a plurality of buffers 23 are distributed around the bottom end of the column body 20 on the ball joint seat 22. Exemplarily, the buffer 23 may be a rubber column. When the driving assembly 30 drives the column body 20 to move upward, in order to avoid the rigid collision between the ball joint seat 22 and the crossbeam of the mounting seat 10 or the walking gantry frame 40, the buffer 23 is provided to buffer the collision force. At the same time, the abutment and limiting effect of the buffer 23 and the mounting seat 10 or the walking gantry frame 40 can be used to prevent the column body 20 from sliding over, thereby improving the safety of the lifting and lowering movement of the column body 20.

[0040] Based on the same inventive concept, Figures 1 to 4 It is understood that the embodiment of the present application also provides an automatic masonry equipment, including the above-mentioned lifting column.

[0041] The beneficial effect of the automatic masonry equipment provided by the utility model is that compared with the prior art, the lifting column of the utility model adopts the above-mentioned lifting column. When the working area needs to be transferred, the driving component 30 can be used to drive the column body 20 and the masonry platform arranged on the column body 20 to rise until the bottom end of the column body 20 is higher than the top surface of the structure, and then the walking gantry frame 40 can be directly transferred to the target position. After the transfer is in place, the driving component 30 drives the column body 20 to descend to form a supporting state, thereby realizing the overall transfer of the equipment without disassembly, which can save the equipment disassembly and reorganization time during the equipment transfer process, thereby improving the equipment transfer efficiency; in addition, based on the supporting state of the column body 20, the load of the walking gantry frame 40 during the masonry construction can be reduced, thereby improving the construction stability.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
