Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the utility model is an underground belt replacing carrier roller device, which is used for replacing a carrier roller of a belt conveyor, and comprises an underframe 1, wherein end covers 3 are arranged at two ends of the underframe 1, an intermediate frame 4 is arranged above the underframe 1, adjusting components 6 are symmetrically arranged between the intermediate frame 4 and the underframe 1, a double-headed screw 2 is arranged inside the underframe 1, diagonal bracing mechanisms 8 are symmetrically arranged on the upper end surface of the intermediate frame 4, the diagonal bracing mechanisms 8 are rotatably connected with the intermediate frame 4, first shaft levers 5 for clamping the diagonal bracing mechanisms 8 are arranged at two sides of the intermediate frame 4, second shaft levers 7 are symmetrically arranged inside the underframe 1, one ends of the adjusting components 6 are rotatably connected with the second shaft levers 7, and the other ends of the adjusting components 6 are screwed on the outer surfaces of the double-headed screw 2.

The adjusting component 6 comprises a first supporting plate 61 rotatably mounted on a second shaft lever 7, a sliding block 62 screwed on the outer surface of the double-headed screw 2, and a second supporting plate 63 rotatably mounted on the sliding block 62, two ends of the double-headed screw 2 respectively penetrate through the two end covers 3, the double-headed screw 2 is rotatably connected with the end covers 3, one end of the double-headed screw 2 is fixedly connected with a rotating handle, the rotating handle is rotated to drive the double-headed screw 2 to rotate clockwise, the two sliding blocks 62 are away from each other, because the upper ends of the second supporting plate 63 and the first supporting plate 61 are rotatably connected with the lower end of the middle frame 4, and the lower end of the first supporting plate 61 is rotatably mounted on the second shaft lever 7, as the two sliding blocks 62 are away from each other, the included angle between the second supporting plate 63 and the first supporting plate 61 is gradually increased, the vertical height of the middle frame 4 is reduced, the overall height of the utility model is changed, and when the double-headed screw 2 rotates anticlockwise, the two sliding blocks 62 are close to each other, namely the vertical height of the middle frame 4 is increased, so that the belt is conveniently supported, and the roller is convenient for a user to replace.

Bracing mechanism 8 contains and rotates the fagging one 81 of being connected with middle frame 4, and rotate and install two 82 of fagging one 81 one side to one side, the draw-in groove 83 that a plurality of was the equidistance and arranges is seted up to the lower surface of fagging two 82, when different draw-in grooves 83 were separated with a 5 card of axostylus axostyle, the inclination of fagging two 82 is different to one side, and then the inclination that drives the fagging one 81 of being connected with middle frame 4 rotation changes, adapt to different inclination's belt, make the belt whole more steady at the in-process of holding up, avoid buckling the damage.

The commonly used belt conveyor comprises a belt and a carrier roller, the carrier roller can be tightly pressed when the belt is in a tensioning state, and the belt carrier roller is not flexible in rotation or needs to be replaced in time when a fault occurs. The method of belt bearing roller of change that is commonly used at present still utilizes artifical: the belt is jacked up by the back of a worker between the upper layer belt and the lower layer belt, the old carrier roller is detached, and then a new carrier roller is jacked up and installed. But the belt feeder of mine usefulness is often heavy, bulky for it is difficult to hold up the belt and take off the bearing roller to rely on the manpower alone: and in the position of changing easily, for example belt middle part bearing roller, 2 people need before the bearing roller, back jack-up belt at the bearing roller to cooperate, need about 10 minutes: to change the difficult position, then need 4-5 people to cooperate and accomplish, 4 people are responsible for jack-up belt, 1 people are responsible for dismouting bearing roller, sometimes still need instruments such as crowbar, jack to help accomplish, correspondingly need about 20-30 minutes: in addition, the space between upper and lower floor's belt is narrow and small, and the workman creeps into the belt and has the potential safety hazard, again because the distance of manpower jack-up belt is limited, the bearing roller dismouting is inconvenient, not handy, the workman cooperation has incoordination and nonconformity slightly, the bearing roller will be extruded or pop out and hinder the people: particularly, in the face of complex working environment under a mine, the safety accident that personnel are injured frequently occurs in the replacement process.

Based on the content disclosed in the embodiment, when the belt conveyor is used, the belt conveyor is firstly placed on a bracket of the belt conveyor, the inclination angle of the inclined supporting plate I81 is adjusted to be more attached to a belt, the handle is rotated, the adjusting assembly 6, the middle frame 4 and the inclined supporting mechanism 8 are matched for use, the belt is stably supported, a worker can remove a belt carrier roller, the operation sequence is opposite when the carrier roller is installed, the belt conveyor can reduce personnel for replacing the belt carrier roller, and the belt conveyor can be completed by one worker; in addition, by means of the belt carrier roller dismounting device, the dismounting space of the belt carrier roller is enlarged, the dismounting of the carrier roller is convenient, the belt carrier roller is relatively simple and easy to replace, and the problem that a worker is difficult to replace the belt carrier roller is solved; the replacement time can be reduced, the problem that the production is influenced due to long time for replacing the belt carrier roller by workers is solved, and the efficiency is improved; meanwhile, safety is guaranteed, on one hand, workers can not enter the belt to replace the upper layer and the lower layer of the belt or enter the belt for one worker, personnel are reduced, and therefore the probability of injury is greatly reduced, on the other hand, the device is clamped on the carrier roller frame and is firm, the jacking mechanism replaces manual jacking, the distance is high, the space is large, and the situations that the waist of the workers are injured and people are injured due to carrier roller ejection cannot occur; finally, the utility model is simple and convenient to manufacture, low in cost, economical and practical.
