Embodiment 1

[0037] see figure 1 As shown in the hydraulic lifting support for a coal conveyor belt, place the support well. At this time, the two branch grooves are parallel, and the two branch grooves 7 hold up the belt. When the belt needs to be replaced, start the hydraulic cylinder 5, and the hydraulic cylinder 5 jack up the hydraulic rod 6, the hydraulic rod 6 jacks up the supporting rod 3, and the supporting rod 3 will move up with the position limited by the lifting rod 2. There are two hydraulic cylinders 5, which are arranged on the lifting rod 2 In the middle, the hydraulic rod 6 is installed on the hydraulic cylinder 5, and the two hydraulic cylinders 5 on both sides are lifted at the same time, which can avoid the belt from being deflected due to uneven force. When the supporting rod 3 is lifted, use The nut 10 locks the safety screw limit block 11, the safety screw limit block 11 and the nut 10 fix the safety screw 9, and the safety screw 9 supports the top block 12, so that ...

Embodiment 2

[0039] see figure 2 In the shown hydraulic lifting support for a coal conveyor belt, in embodiment 2, on the basis of embodiment 1, a rubber pad 24 is provided at the bottom of the support 1, and the rubber pad 24 is arranged around the bottom edge of the support 1, which can So that the bracket will not wear the ground. A chute 13 is set below the branch groove 7, and a slide table 14 is set on the top of the supporting rod 3. The slide table 14 is T-shaped, and the chute 13 and the slide table 14 can be fitted together. The branch grooves 7 have different sizes and specifications and can be replaced. On the left side and the right side of the lifting rod 2, one more safety screw limit block 11 is respectively arranged, and the nuts 10 are respectively arranged on the safety screw 9, and the nuts 10 are arranged in pairs. On the safety screw 9, the nuts 10 are respectively located above and below the newly set safety screw stop blocks 11, and the two safety screw stop bloc...

Embodiment 3

[0041] see image 3 In the shown coal belt hydraulic lifting support, on the basis of embodiment 1, several roller shafts 21 and rollers 22 are arranged under the support 1, and the roller shafts 21 are connected inside the support 1 , the roller 22 is installed on the roller shaft 21, so that the support can be moved as a whole, and several roller boxes 23 are arranged under the support 1, and the roller shaft 21 and the roller 22 are arranged in the roller box 23, The roller shaft 21 is connected in the roller box 23, the roller 22 is mounted on the wheel shaft 21, a connecting plate 26 is arranged above the roller box 23, and a roller elevating rod is arranged above the connecting plate 26 25. The roller box 23 can be raised and lowered by the roller elevating lever 25, so that the roller 22 can move up and down. When not in use, the roller 22 can be put away to prevent the support from sliding.

[0042] When the support needs to move, start the roller lifting lever 25, th...

Abstract

The invention relates to the technical field of hydraulic supports, in particular to a hydraulic lifting support for a coal conveying belt. The hydraulic lifting support for the coal conveying belt comprises a supporting seat, a lifting rod, a bearing rod, a fixing steel bar, a hydraulic cylinder, a hydraulic rod, a supporting groove, a top plate, a safety screw, a nut, a safety screw limiting block, a top block, a sliding groove, a sliding table, a roller shaft, a roller, a roller box, a rubber pad, a roller lifting rod, a connecting plate, a cross-shaped lifting groove, an I-shaped clamping plate shaft, a roller clamping plate, a perforated connecting plate, a roller round box, a roller set and a roller shaft set. The hydraulic lifting support for the coal conveying belt has the advantages that the bearing rod can be synchronously lifted through hydraulic driving, the labor cost is saved, the risk of lifting through two forklifts is reduced, and the hydraulic lifting support is easy to use in places with limited space, and can be used as a supporting frame at ordinary times; and the whole support can be moved through the roller lifting rod, so that short-distance movement is more convenient.

Description

technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to a coal conveyor belt hydraulic lift support. Background technique [0002] After the belt conveyor of the fuel system of the power plant runs for a long period of time, the belt conveying the fuel will have defects such as severe wear and aging. On the support frame, it is easy to be pulled to the belt conveyor to complete the laying; [0003] At present, the existing support frame is formed by combining channel steel, which is a set of two support frames and a pair of thick-walled steel pipes (which act as shoulder poles to lift the belt). The height of the support frame is fixed and requires the use of mechanical The equipment lifts up the new belt before placing it on the support frame; the weight of the existing new belt is more than 10 tons, and the heaviest can reach 16 tons. Because the new belt is delivered in a whole roll, the diameter can reach 2.75 meters, ...
