DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0028] like Figure 1 , Figure 2 As shown, Figure 1 A side view of a furnace top hoisting system is provided for an embodiment of the present application. Figure 2 A top view of a furnace top hoisting system is provided for an embodiment of the present application. A furnace top hoisting system for a continuous casting tunnel furnace includes a main body 100, an adjustment member 200, a counterweight member 300 and a hoisting member, wherein:

[0029] like Figure 1 , Figure 2 As shown, a connecting portion 101 for connecting to a lifting device is provided in the middle of the main body 100 , and the main body 100 has a first working end and a second working end, and a plurality of connecting positions 102 are provided at intervals on the first working end.

[0030] The main body 100 serves as the intermediate foundation of the entire furnace roof hoisting system, ensuring stability and reliability under high temperature and heavy load conditions. A connecting portion 101 is provided in the middle of the main body 100, and the connecting portion 101 is used to connect with a hoisting device such as a crane or a hook to realize the hoisting operation of the furnace roof.

[0031] like Figure 1 , Figure 2 As shown, the main body 100 is provided with a first working end and a second working end, and the two working ends respectively assume different functions. The first working end is close to the installed counterweight 300, and the second working end is close to the working furnace top 500.

[0032] A plurality of spaced connection positions 102 are provided on the first operation end. The connection positions 102 are used to install the adjustment member 200. The spacing and number of the connection positions 102 can be adjusted according to actual needs to adapt to different operation requirements.

[0033] The adjusting member 200 is fixedly connected to the main member 100 , and the adjusting member 200 is detachably disposed on one of the connecting positions 102 to change the distance between the adjusting member 200 and the second working section.

[0034] like Figure 1 , Figure 2As shown, the adjusting member 200 is fixedly connected to the main member 100, but can be detachably arranged on the connecting position 102 at different positions. The main function of the adjusting member 200 is to adjust the distance between the adjusting member 200 and the second working end, so that the relative position of the adjusting member 200 can be flexibly changed according to different furnace roof sizes, shapes and weights, so that the adjusting member 200 and the second working end have different distance states compared with the connecting portion 101 on the main member 100, ensuring that the two sides of the connecting portion 101 of the main member 100 obtain different lengths of force arms, so that the working furnace roof 500 can be correctly and safely hoisted.

[0035] like Figure 1 , Figure 2 As shown, the counterweight 300 is detachably connected to the adjusting member 200, and the counterweight 300 is detachably connected to the adjusting member 200. The counterweight 300 provides necessary balance during the hoisting process to prevent the main member 100 from tilting or flipping due to uneven weight distribution. The position of the counterweight 300 can be adjusted relative to the adjusting member 200 according to actual hoisting requirements to ensure the stability and safety of the hoisting operation.

[0036] like Figure 1 As shown, the hoisting member is fixedly arranged on the second working end and is used to connect the working furnace roof 500. The hoisting member is fixedly installed on the second working end of the main body 100 and is directly connected to the working furnace roof 500. The hoisting member ensures that the working furnace roof 500 can be firmly connected during the hoisting process to prevent sliding or falling off. In the hoisting operation of the furnace roof of the continuous casting tunnel furnace, the various variables in the actual operation can be flexibly adjusted to ensure the efficiency and safety of the hoisting operation.

[0037] like Figure 1As shown, in an optional embodiment, the furnace top hoisting system in the present application is used for auxiliary hoisting operations of a continuous casting tunnel furnace, and the furnace top hoisting system includes a main body 100 and an adjusting member 200, wherein a connecting portion 101 for connecting a hoisting device is provided in the middle of the main body 100, and the main body 100 has a first working end and a second working end, and a plurality of connecting positions 102 are provided on the first working end at intervals, and the adjusting member 200 is fixedly connected to the main body 100, and the adjusting member 200 is detachably arranged on one of the connecting positions 102 to change the distance between the adjusting member 200 and the second working section, and a counterweight 30 is detachably connected to the adjusting member 200. 0, a hoisting part is fixedly provided on the second working end, and is used to connect the working furnace roof 500. When actually working, the connecting part 101 on the main part 100 is used as the hoisting connection point through the hoisting equipment in the working environment, and is installed and fixed on the working furnace roof 500 of the continuous casting tunnel furnace through the hoisting part on the main part 100. The counterweight 300 provides counterweight at the first working end and achieves hoisting balance. After the hoisting operation of the hoisting equipment, the hoisting operation of the working furnace roof 500 is completed. In a complex working environment, the hoisting operation stability is maintained, and the working position of the hoisting equipment can be flexibly arranged. Under the working condition of limited workshop structure space, the interference position can be flexibly avoided to perform reliable operation, thereby ensuring operation safety and improving efficiency.

[0038] like Figure 1 As shown, in an optional embodiment, the adjusting member 200 is sleeved on the first working end of the main member 100, and the adjusting member 200 is provided with a plurality of positioning holes 201 corresponding to the connection, and a locking member 202 fixedly connected to the main member 100 is passed through the positioning hole 201.

[0039] The adjusting member 200 is sleeved on the first working end of the main member 100 to allow the adjusting member 200 to be flexibly moved on the main member 100 to meet different working requirements. The displacement direction of the adjusting member 200 is based on the common center line with the main member 100 to adjust the relative position and posture of the furnace top hoisting system as a whole, thereby ensuring the stability and safety of the working furnace top 500 during the hoisting process.

[0040] The adjusting member 200 is provided with a plurality of positioning holes 201 corresponding to the connection position 102. The number and distribution of the positioning holes 201 can be determined according to the actual configuration specifications. Each positioning hole 201 corresponds to the connection position 102 on the main member 100, so that the adjusting member 200 can be quickly and accurately positioned on the main member 100. This not only improves the flexibility of the hoisting system, but also ensures that accurate hoisting operations can be achieved under different working conditions.

[0041] like Figure 1 , Figure 2 As shown, a locking piece 202 fixedly connected to the main body 100 is provided in the positioning hole 201. The function of the locking piece 202 is to ensure that the adjusting piece 200 can be firmly fixed after being adjusted to a suitable position, so as to prevent the adjusting piece 200 from shifting due to vibration or load changes during the hoisting process. The locking piece 202 can be configured to be made of high-strength material to ensure that the stability and reliability of its structure can be maintained in a high-temperature and heavy-loaded operating environment. The use of the locking piece 202 in conjunction with the positioning hole 201 provides a reliable locking mechanism, so that the operator can easily adjust the relative position of the adjusting piece 200 and ensure that the adjusted setting remains unchanged during the operation, especially in a high-temperature and heavy-loaded industrial environment such as a continuous casting tunnel furnace, which improves the efficiency of the hoisting operation and enhances the safety of the operation.

[0042] like Figure 1 , Figure 2 As shown, in an optional embodiment, the locking member 202 includes a plurality of bolts, and the plurality of bolts are passed through the plurality of positioning holes 201 and fixedly connected to the plurality of connecting positions 102 .

[0043] The locking members 202 are configured as a plurality of bolts to ensure that they can withstand various forces that may be encountered during the lifting process, such as tension, compression and shearing forces. A plurality of bolts are inserted into the plurality of positioning holes 201 to provide a strong fixing force and also allow the adjusting member 200 to be flexibly adjusted on the main member 100. Each connection position 102 is a preset fixing point on the main member 100, which, when used in conjunction with the bolts, can ensure that the adjusting member 200 is securely locked after being adjusted to a suitable position. It can remain stable even under heavy loads and vibrations, thereby improving the safety and reliability of the operation, as well as the flexibility and efficiency of the operation.

[0044] like Figure 1 , Figure 2 As shown, in an optional embodiment, a fixed platform 204 is provided between the adjusting member 200 and the counterweight member 300 , the fixed platform 204 is fixedly connected to the adjusting member 200 , at least two mounting rods 205 are provided on the fixed platform 204 , and the counterweight member 300 is detachably provided on the mounting rods 205 .

[0045] The fixed platform 204 between the adjusting member 200 and the counterweight 300 provides a stable support base for the counterweight 300. At least two mounting rods 205 are provided on the fixed platform 204. The mounting rods 205 not only provide physical connection points for mounting the counterweight 300, but also ensure the correct positioning and reliable fixation of the counterweight 300. The structural strength configuration of the mounting rods 205 is embodied in the bearing capacity to ensure that the weight of the counterweight 300 can be safely supported, and it is also convenient for the installation and removal of the counterweight 300.

[0046] like Figure 1 , Figure 2 As shown, in an optional embodiment, the counterweight member 300 includes a plurality of counterweight units, each of which is provided with a receiving hole for the mounting rod 205 to pass through, and the counterweight unit is mounted on the mounting rod 205 through the receiving hole.

[0047] Multiple counterweight units are detachably mounted on the mounting rod 205, allowing the operator to quickly change the weight of the overall counterweight 300 by the number of counterweight units according to specific lifting requirements. The detachability of the counterweight unit greatly improves flexibility and adaptability, allowing the system to adapt to different operating conditions and load requirements. The installation and removal process of the counterweight unit is simple and quick, and does not require complex tools or equipment, thereby saving time and labor.

[0048] like Figure 1 , Figure 2 As shown, in an optional embodiment, the mounting rod 205 is threadedly connected with a supporting block 206 supported under the counterweight unit, and a pressing block 207 pressed on the counterweight unit.

[0049] The mounting rod 205 is threadedly connected with a support block 206 supported under the counterweight unit and a pressure block 207 pressed on the counterweight unit. The support block 206 and the pressure block 207 are connected to the mounting rod 205 by threads. This threaded connection method not only provides a strong fastening force, but also allows the positions of the support block 206 and the pressure block 207 to be quickly adjusted when necessary, so as to facilitate the increase or decrease of the number of counterweight units. The self-locking characteristics of the threaded connection ensure that the counterweight unit will not loosen due to vibration during the lifting process.

[0050] The support block 206 bears the vertical pressure of the counterweight unit to prevent the counterweight unit from being displaced or falling off during the lifting process. The pressure block 207 is located above the counterweight unit and is connected to the mounting rod 205 by threads. During the lifting process, the pressure block 207 applies a certain pressure to the counterweight unit to ensure close contact between the counterweight unit and the support block 206 to prevent the movement of the counterweight unit due to vibration or impact.

[0051] like Figure 1 , Figure 3As shown, Figure 3 A local schematic diagram of the transverse portion 401 is provided for an embodiment of the present application. In an optional embodiment, the hanging member includes a transverse portion 401 fixed to the upper portion of the second working end and arranged vertically with the main body 100, and the transverse portion 401 is provided with a plurality of flexible hanging portions 402 for connecting to the working furnace top 500.

[0052] The transverse portion 401 is fixed on the main body 100, providing a space for the flexible lifting portion 402 to be arranged in the length direction of the transverse portion 401, so that after the flexible lifting portion 402 is connected to the working furnace roof 500, it can maintain the stability of the working furnace roof 500 during the lifting process. The transverse portion 401 is perpendicular to the main body 100, so as to fully utilize the space in this direction through the transverse portion 401 and maintain the lightweight layout of the main body 100.

[0053] like Figure 1 , Figure 2 As shown, in an optional embodiment, at least four flexible lifting parts 402 are provided, and the ends of the flexible lifting parts 402 are provided with lifting bolts 403 that can be fixed to the working furnace top 500 to maintain the connection stability of the flexible lifting parts 402, and when connecting, the working furnace top 500 is connected through the lifting screws at one end of the flexible lifting parts 402.

[0054] like Figure 1 , Figure 3 As shown, in an optional embodiment, support blocks 404 fixedly connected to the transverse portion 401 are respectively provided on both sides of the main body 100 to improve the connection stability between the main body 100 and the transverse portion 401, and the support blocks 404 can be respectively connected to the main body 100 and the transverse portion 401 by welding.
