Description

Technical Field

[0001] This invention relates to an assembly equipment and process for an ultra-large hoist sheave, belonging to the technical field of hoist sheave assembly equipment. Background Technology

[0002] For ultra-deep mines with depths exceeding 1500 meters or 2000 meters, a larger steel structure headframe is required, and the installation of the hoisting sheave increases the difficulty.

[0003] The existing assembly of the top wheel of the super-large hoist usually involves large cranes to assemble it in the air, which is relatively slow. The hoisting of the top wheel after the derrick is built is more difficult and costly. Summary of the Invention

[0004] The main purpose of this invention is to solve the problems of high hoisting difficulty, high construction cost, and high difficulty in assembling the large size of the sheave in the air, and to provide an assembly equipment and process for an ultra-large hoist sheave.

[0005] The objective of this invention can be achieved by adopting the following technical solution:

[0006] An assembly device for an ultra-large hoist sheave includes assembly equipment, hoisting equipment, and sheave body;

[0007] The assembly equipment includes: a base and two assembly platforms installed on the upper end of the base, with two I-beams installed on the base between the two assembly platforms, and a lifting component between the two I-beams;

[0008] The lifting equipment includes: a crane;

[0009] The main body of the celestial wheel includes: a main shaft, a lower celestial wheel, and an upper celestial wheel.

[0010] Furthermore, the lifting component includes two hydraulic jacks and a channel steel installed at the output end of the hydraulic jacks, with an arc-shaped steel welded to the upper end of the channel steel.

[0011] A construction process for assembling a super-large hoist sheave includes the following steps:

[0012] S1: Assemble the assembly equipment and install the two assembly platforms according to the dimensions of the sheave body;

[0013] S2: Adjust the assembly equipment, adjust and install the I-beams between the two assembly platforms in the corresponding positions to prevent the lower end of the lower sheave from contacting the ground, and reserve space for the assembly of raised components;

[0014] S3: Assemble the main body of the ceremonial wheel. Install the lower ceremonial wheel step by step by raising the components, and then assemble the upper ceremonial wheel.

[0015] S4: The sheave is being hoisted onto the derrick;

[0016] S5: Alignment of the top wheel body, assembly complete.

[0017] Furthermore, the assembly platform adopts a derrick box, which is assembled on the base and leveled. Then, it is stacked and fixed upwards according to the size of the sheave body, and reinforced with steel pipes.

[0018] Furthermore, step S3 also includes the following processes:

[0019] A1: Inspect the sheave wheel and prepare for installation after it passes inspection;

[0020] A2: Assemble the lower sheave. Use a crane to lift the lower sheave between the two assembly platforms and place it on the two I-beams assembled on the base. At this time, the crane remains in the lifting position.

[0021] A3: Assemble the main shaft. Use another crane to lift the main shaft and assemble it with the fixed lower sheave. Clean and lubricate the bearing housing on the main shaft. Then, move the two cranes out.

[0022] A4: Assemble the upper sheave. After the main shaft and lower sheave are assembled, the upper sheave is hoisted by a crane, and the main shaft is assembled to form a complete sheave body.

[0023] Furthermore, during the assembly of the main shaft and the lower sheave, the lower sheave is lifted by a lifting component, so that the arc-shaped steel in the lifting component is pressed against the lower wheel groove on the lower sheave. Two hydraulic jacks are used to lift it upwards simultaneously, and finally the lower sheave is pressed against the main shaft before assembly.

[0024] Furthermore, step S4 also includes the following feature: after the sheave platform on the derrick is hoisted and before the top platform is installed, the assembled sheave body is hoisted using a crane.

[0025] Furthermore, step S5 also includes the following features: using a pre-arranged line and frame level for alignment, during which a shim with a thickness of 0.2mm to 0.5mm can be sandwiched between the bearing seat of the sheave body and the base plate of the sheave body, and the levelness of the sheave body can be corrected by adjusting the thickness of the shim.

[0026] Furthermore, the gasket material is either galvanized iron sheet or copper sheet.

[0027] Furthermore, when aligning the sheave, one of two methods can be used: laterally moving the sheave bearing seat with a hydraulic jack or using bolt clamps to move it.

[0028] The beneficial technical effects of this invention are as follows: The ultra-large hoist sheave assembly equipment and process of this invention make full use of the derrick box to build an assembly platform, reducing the difficulty of assembling the sheave. At the same time, during the assembly of the sheave, a simple and easy-to-assemble lifting component is used to lift the lower sheave, which saves time and does not require special tools. It is easy to use, disassemble and carry, and has a high degree of adaptability. This construction process is interspersed in the process of large crane bulk derrick assembly, making full use of the crane used for derrick hoisting to lift the sheave. Moreover, when the sheave is being hoisted, the top platform of the derrick is not installed, which greatly shortens the overall construction period of the mine hoisting system and reduces the difficulty and construction risk of hoisting and positioning the sheave.

[0036] A construction process for assembling a super-large hoist sheave includes the following steps:

[0037] S1: Assemble the assembly equipment and install the two assembly platforms 1 according to the dimensions of the sheave body 2;

[0038] S2: Adjust the assembly equipment, adjust and install the I-beam 5 between the two assembly platforms 1 in the corresponding position to prevent the lower end of the lower sheave from contacting the ground, and reserve space for the assembly of raised components.

[0039] S3: Assemble the sheave body 2. Install the lower sheave gradually by lifting the components, then assemble the upper sheave. Inspect the sheaves; after acceptance, prepare for installation. Assemble the lower sheave using crane 6, placing it between the two assembly platforms 1 and supporting it on two I-beams 5 mounted on the base 4. Crane 6 remains in the lifting position. Assemble the main shaft 3 using another crane 6, assembling it with the fixed lower sheave. Clean and lubricate the bearing seats on the main shaft 3, then remove both cranes 6. Assemble the upper sheave. After the main shaft 3 and lower sheave are assembled, assemble the upper sheave using crane 6 and assemble the main shaft, forming the complete sheave body.

[0040] S4: The sheave is hoisted onto the derrick. After the sheave platform is hoisted onto the derrick, before the top platform is installed, the assembled sheave body 2 is hoisted using a crane.

[0041] S5: Alignment of the sheave body. Alignment is performed using a pre-arranged line and frame level. During alignment, shims with a thickness of 0.2mm to 0.5mm can be placed between the bearing seat and the base plate of the sheave body. The levelness of the sheave body 2 is corrected by adjusting the thickness of the shims. The shims are made of either galvanized iron or copper. When positioning and aligning the sheave, the sheave bearing seat is moved laterally by a hydraulic jack or by using bolt clamps. Assembly is then complete.

[0042] Assembly platform 1 uses a derrick box, which is assembled on the base and leveled. Then, it is stacked and fixed upwards according to the size of the sheave body 2, and reinforced with steel pipes.

[0043] During the assembly of the main shaft 3 and the lower sheave, the lower sheave is lifted by the lifting component, so that the arc-shaped steel 9 in the lifting component is close to the lower wheel groove on the lower sheave. The two hydraulic jacks 7 are lifted upwards simultaneously, and finally the lower sheave is close to the main shaft 3 before assembly.
