[0028] The bracket 8 and the lifting block 11, the bracket 8 is connected to the lifting slider 5, and several groups of lifting adjustment frames 10 are arranged on the bracket 8, and each group of lifting adjustment frames 10 is provided with a group of lifting blocks 11, and the lifting blocks 11 are used to lift rollers; the bracket 8 is provided with two groups, and the bracket 8 is installed with hinge blocks 9, each group of hinge blocks 9 is hinged with its corresponding group of adjustment cylinder 7 output ends, and the number of lifting adjustment frames 10 is equal to the number of lifting blocks 11; through the lifting mechanism on the main support 2, the rollers can be automatically driven to rise, which reduces the labor intensity of manual handling of the rollers and reduces the risk of work-related injuries caused by workers carrying heavy objects. At the same time, the device can be flexibly adjusted in height and position according to actual working conditions to adapt to the replacement needs of rollers at different heights, solving the problem that traditional devices cannot handle various complex working environments; using the combined design of the bracket 8 and the lifting block 11, the lifting adjustment frame 10 can stably support and transport rollers of different specifications and shapes, overcoming the limitation that traditional handling devices are only applicable to rollers of a single specification.

[0029] As a preferred embodiment of the above embodiment, the lifting mechanism includes a transmission rod 14, an eccentric transmission block 15, a lifting chain 16 and an articulated sleeve 17. The transmission rod 14 is rotatably arranged on the main support 2. Two groups of eccentric transmission blocks 15 are symmetrically arranged at both ends of the transmission rod 14.

Compared with direct sliding contact, the rolling contact between the guide wheels 19 and the guide rails 20 greatly reduces the friction coefficient between the two, effectively reduces the wear between the components, extends the service life of the equipment, and reduces the energy consumption during the lifting process.

[0031] As a preferred embodiment of the above-mentioned embodiment, two groups of guide wheel mounting blocks 21 are provided on both side ends of the lifting plate 3, and stabilizing guide wheels 22 are rotatably provided on the guide wheel mounting blocks 21, and the stabilizing guide wheels 22 are rollingly fitted with the guide rails 20; the rolling fit between the stabilizing guide wheels 22 and the guide rails 20 can not only ensure that the lifting plate 3 moves accurately along the set track during the up and down movement, but also effectively prevent the lifting plate from lateral displacement or shaking during the movement, thereby enhancing the stability of the overall structure and ensuring the safety and accuracy of the roller replacement operation; the added stabilizing guide wheels 22 share part of the load of the guide wheels 19, thereby enhancing the load-bearing capacity and torsional stiffness of the entire lifting mechanism.

[0032] As a preferred embodiment of the above embodiment, the axis of the stabilizing guide wheel 22 is perpendicular to the axis of the guide wheel 19; the stabilizing guide wheel 22 and the guide wheel 19 respectively provide two independent guiding functions perpendicular and parallel to the movement direction of the lifting plate 3, forming a three-dimensional guiding system, which can effectively prevent the lifting plate 3 from shaking and deflecting in any direction during the lifting process, significantly enhance the stability of the lifting process, and ensure the accuracy and safety of the roller replacement operation; at the mining site, the environment is often complex and changeable, and the terrain is undulating. This design can adapt to different terrains and working conditions, and can ensure the smooth movement of the lifting plate 3 and the smooth completion of the roller replacement operation even on inclined or uneven ground.

[0034] As a preferred embodiment of the above embodiment, the lifting and adjusting frame 10 is slidably mounted on the bracket 8, and a plurality of groups of adjusting bolts 23 are interspersed on the lifting and adjusting frame 10, and a group of nuts 24 are threadedly sleeved on each group of adjusting bolts 23; through the sliding and clamping design of the lifting and adjusting frame 10 on the bracket 8, it can be flexibly adjusted according to the different diameters and widths of the rollers to be replaced, thereby expanding the application range of the transporting device so that it can adapt to rollers of different specifications; by screwing the adjusting bolts 23 and the nuts 24, the position and height of the lifting block 11 can be accurately adjusted to ensure that the lifting block can firmly and properly support the rollers, and avoid the rollers from shaking or slipping during transportation, thereby ensuring the safety and accuracy of the replacement operation.

[0035] As a preferred embodiment of the above embodiment, a protective cover 26 is provided on the outer wall of the main support 2; the protective cover 26 can effectively shield the internal transmission components, cylinders, motors and other important equipment. During operation and maintenance, the protective cover 26 can prevent maintenance personnel from accidentally touching high-speed rotating or high-voltage components, thereby reducing the possibility of work-related accidents and improving operational safety.

[0036] The utility model relates to a replacement and handling device for a mining conveyor roller. When the device is in operation, the maintenance personnel first move the device to the position of the roller to be replaced, and use the universal moving wheel 25 to flexibly enter a narrow and complex working environment. According to the specifications of the roller to be replaced, the adjusting bolts 23 and nuts 24 on the lifting and adjusting frame 10 are adjusted to make the lifting block 11 adapt to rollers of different sizes. The motor 12 is started, and the motor drives the transmission rod 14 to rotate through the chain and sprocket transmission. The eccentric transmission blocks 15 at both ends of the transmission rod 14 drive the articulated sleeve 17 to swing, and then pull the lifting chain 16 to move, so that the lifting rod 18 at the bottom end of the lifting chain 16 drives the lifting plate 3 to descend. The maintenance personnel place the roller to be replaced on the adjusted lifting block 11, which is carried by the bracket 8, and reverse the motor 12 to drive the lifting plate 3 to translate upward. The guide wheel 19 and the stabilizing guide wheel 22 ensure that the lifting process is stable and does not deviate. When the roller is lifted to a suitable height, the mobile device as a whole reaches the installation position of the new roller.

[0037] The installation method, connection method or setting method of the mining conveyor roller replacement and handling device of the utility model are all common mechanical methods, and can be implemented as long as the beneficial effects can be achieved.
