DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and examples.

[0027] The mine shaft is an important infrastructure in the mining process. Some mining and ventilation equipment are installed in the mine shaft. The relevant equipment is gradually lifted to the predetermined position in the shaft by lifting equipment, and the installation is gradually completed.

[0028] Existing hoisting equipment is similar to ground hoisting equipment, and includes a hoisting platform and a lifting device for controlling the up and down movement of the hoisting platform; wherein the equipment or structure to be hoisted is placed on the hoisting platform for position limiting and fixing.

[0029] Some mining equipment or cargo are large in size and weight. When they are placed on the lifting platform on the mine ground, their placement position is not the predetermined center position. This will cause the mining equipment or cargo to be subjected to unstable force on the lifting platform surface, with one side being subjected to greater force than the other side. This can easily cause the lifting platform to be unstable during the lifting process, causing shaking or even breaking and falling off, affecting the installation and lifting in the mine shaft.

[0030] Some research equipment has improved the lifting platform by setting a structure at the lower end of the lifting platform that can control the movement of lifting equipment or cargo. The equipment or cargo on the upper end of the lifting platform can be moved to the center of the lifting platform, and the equipment or cargo can be kept in the center of the lifting platform, thereby ensuring its stability during lifting in the mine shaft. However, the above solution requires larger volume and relatively complex equipment for the movement of equipment or cargo, especially when the volume and mass of the cargo are large and the bottom is irregular, which places higher requirements on the structure of the mobile cargo, and the shaft lifting process and preparation stage take longer, resulting in limited efficiency.

[0031] Refer to the attached Figure 1 -Attached Figure 6 A mine shaft hoisting method adopts different schemes to determine the distribution position of the cargo 200 on the surface of the load-bearing platform 100, calculate the position of the overall center of gravity of the load-bearing platform 100 and the cargo 200, and then change the hoisting position of the hoisting components 400 around the load-bearing platform 100, control the cargo 200 to be located at the center position of multiple hoisting components 400, ensure the stability of the force of the hoisting components 400 around the load-bearing platform 100, avoid uneven force during the hoisting process, and ensure stability and safety during the hoisting process.

[0032] The above-mentioned lifting assembly 400 includes a plurality of first lifting ropes 410 . This article takes the supporting platform 100 as a rectangle and installs four first lifting ropes 410 around the supporting platform 100 as an example for description.

[0033] At least three installation notches 110 are provided on the upper end of the load-bearing platform 100. A control device 300 is installed in the installation notches 110. The first end of the first lifting rope 410 is connected to the control device 300, and the second end is connected to the lifting equipment, thereby achieving the lifting of the entire load-bearing platform 100. The position of the first lifting rope 410 can be adjusted by the control device 300 to attach the load-bearing platform 100. Figure 3For example, the positions of the two first lifting ropes 410 below can be changed to adjust the actual carrying width of the carrying platform 100. Similarly, the positions of the two first lifting ropes 410 on the left can be changed to adjust the actual carrying length of the carrying platform 100, which can adjust the actual carrying area in two directions.

[0034] The above-mentioned installation notches 110 can also be designed as four, which can be adjusted synchronously in the four directions of up, down, left and right. The adjustment efficiency is higher and it can be quickly adjusted according to the distribution position of the goods 200; however, compared with 3 installation notches 110 and the control device 300, its cost is higher and the control is more complicated.

[0035] The control device 300 here includes a first control component 310 and a second control component 320. The first control component 310 can be used to adjust the length of the bottom displacement of the first lifting rope 410, and the second control component 320 can be used to adjust the deflection angle of the first end of the first lifting rope 410 by adjusting the deflection angle of the first control component 310; through the combination of the first control component 310 and the second control component 320, the position of the first end of the first lifting rope 410 in the length direction or the width direction can be controlled to achieve adjustment of the actual bearing area of ​​the bearing platform 100. The cooperation of the first control component 310 and the second control component 320 can complete automatic adjustment in two directions, and can also superimpose and summarize the two directions to achieve adjustment of different positions on a surface, thereby increasing the range of adjustment and improving the accuracy of adjustment.

[0036] Compared with the traditional control structure designed separately in two directions, the above structure has higher control efficiency and a simpler and more stable structure. In particular, it can control the first end of the first lifting rope 410 to be located at different positions on a surface within the installation notch 110, thereby improving the range and accuracy of the position adjustment of the first lifting rope 410, thereby ensuring the stability of the overall state of the cargo 200 after adjustment, and further improving the efficiency of adjustment.

[0037] The first control component 310 here is preferably a screw control structure, including a control base 311, a control groove 312 is opened inside the control base 311, an electrically controlled rotating first control screw 314 and a first control slider 313 mounted on the outside of the first control screw 314 are installed in the control groove 312. During the process of controlling the rotation of the first control screw 314, the first control slider 313 can be adjusted to different positions to achieve the adjustment of the moving length of the first lifting rope 410 (adjustment of the radius position).

[0038] Through the screw control structure, the control effect is stable and the stroke is precise. After the adjustment is completed, the locking effect between the first control slider 313 and the first control screw 314 is good, and the locking state is stable, which ensures stability during the subsequent lifting of the cargo 200.

[0039] The second control component 320 here is preferably a hydraulic control structure, including a hydraulic rotating element 321 and a rotating shaft 322. The rotation of the rotating shaft 322 is controlled by the hydraulic rotating element 321. The rotating shaft 322 is fixedly connected to the first control component 310 and is used to adjust the overall deflection angle of the first control component 310. It can achieve adaptive adjustment of the first control component 310 in the length direction or width direction.

[0040] The control is achieved by designing a hydraulic structure with a simple structure, strong control force and good control effect. At the same time, a guide slider is installed on the side of the first control component 310 away from the rotating shaft 322. The first control component 310 is connected to the inner wall of the installation notch 110 through the guide slider, which further ensures the overall stability of the guide slider.

[0041] The lifting assembly 400 here also includes an intermediate platform 420 and a second lifting rope 430. The intermediate platform 420 is located in the middle position and can connect the first lifting rope 410 and the second lifting rope 430 on both sides. Through the segmented structure, the stability of the overall structure can be ensured.

[0042] A scanning device 600 is also installed on the upper end of the carrying platform 100. The scanning device 600 can scan the goods placed on the upper end of the carrying platform 100. Under the premise of a certain density of the goods, the center of gravity of the carrying platform 100 and the goods 200 can be determined by scanning the distribution position of the goods. The scanning device 600 here is electrically connected to the control device 300, and the position of the control device 300 is adjusted by the information scanned by the scanning device 600 to achieve adaptive adjustment.

[0043] The scanning device 600 here includes a scanning end that can perform image scanning to determine the distribution position of the goods 200. For a larger-sized carrying platform 100, the scanning device 600 also includes a rotating joint for controlling the deflection of the scanning end, which is used to control the deflection angle of the scanning end to achieve adaptive control.

[0044] After the position of the first end of the first lifting rope 410 changes, the first lifting rope 410 will become loose or taut. In order to compensate for the length of this part and avoid changes in the overall horizontal structure of the supporting platform 100, a compensation device 500 structure is set on the surface of the first lifting rope 410 to compensate for the changed length of the first lifting rope 410, so as to ensure that the first lifting rope 410 maintains a suitable taut state during the lifting process, and at the same time ensures that the supporting platform 100 is in a horizontal state, thereby ensuring the safety and stability of the cargo 200 during the lifting process.

[0045] Please refer to the attached Figure 6 The compensation device 500 preferably includes a compensation shell 510, and a length adjustment device is installed inside the compensation shell 510. The length adjustment device is connected in series between the first lifting ropes 410 and is used to adjust the lengths of the first lifting ropes 410 on both sides; a second control screw rod 520 and a second control slider 530 are installed in the compensation shell 510, and the second control slider 530 here is in a fixed state. The second control screw rod 520 and the second control slider 530 are threadedly connected, and a driving structure for controlling the rotation of the second control slider 530 is also provided on the outside. The rotation of the second control screw rod 520 is controlled by the driving structure. Under the premise that the position of the second control slider 530 remains unchanged, the second control screw rod 520 here moves linearly along the predetermined length direction to achieve length tightness adjustment.

[0046] Similarly, the control accuracy is high, the control effect is stable, and the locking effect is good through the screw rod adjustment.

[0047] The driving structure here includes a compensating rotating element 550 and a telescopic rotating shaft 540. The first end of the telescopic rotating shaft 540 is fixedly connected to the second control screw 520, and the second end is fixedly connected to the end of the output shaft of the compensating rotating element 550. It can control the torque transmission while having a telescopic length to ensure the normal transmission of torque.

[0048] A compensator 560 can also be installed between the second control screw rod 520 and the first lifting rope 410. The compensator 560 here has a certain elasticity and can achieve the effect of adjusting the buffer. At the same time, the compensator 560 here has a built-in tension test structure. Through the tension test, the magnitude of the tension at the first lifting rope 410 can be determined, and it can be combined with the scanning device 600 to ensure that the center of gravity of the supporting platform 100 is in a stable state in the middle during the lifting process.

[0049] The lifting process specifically includes the following steps:

[0050] S1. Place the cargo 200 at a predetermined position on the upper end of the carrying platform 100.

[0051] S2. Scan the cargo 200 on the upper end of the carrying platform 100 by the scanning device 600, and determine the actual center of gravity position of the carrying platform 100 and the cargo 200 according to the scanning result and the material type of the cargo 200.

[0052] S3. Adjust the actual bearing area of ​​the bearing platform 100 and the lifting assembly 400 according to the position of the actual center of gravity obtained in step S2 until the actual center of gravity of the bearing platform 100 and the cargo 200 is located at the center of the actual bearing area; the above-mentioned actual bearing area is a predetermined area, which can be a rectangular area or a trapezoidal area or other shapes according to actual bearing requirements.

[0053] In which, in step S3, the actual bearing area of ​​the lifting component 400 is adjusted by the control device 300. The lifting component 400 includes a first lifting rope 410. The relative position between the first end of the first lifting rope 410 and the bearing platform 100 is adjusted by the control device 300 to adjust the actual bearing area of ​​the bearing platform 100 and the lifting component 400.

[0054] In summary, through the above scheme, the actual bearing area of ​​the bearing platform 100 is adjusted to ensure that the center of gravity of the cargo 200 can be located in the center, thereby ensuring the safety and stability of the mine shaft hoisting; and, this scheme does not require the movement of the cargo 200, simplifies the relevant structure, reduces the difficulty of operation, and improves the efficiency of the hoisting operation. The overall scheme has high adaptability.

[0055] This article takes mine shaft hoisting as an example to illustrate. Without violating the core concept of the present invention, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
