Problems solved by technology

[0003] However, due to the limitation of the structure, the existing secondary transport device cannot realize turning. When turning is required, it has to be dismantled and manually bypassed the turning surface, and then reassembled. When the turning surface is excavated, the secondary transport cannot be used, but now Existing technology cannot solve this problem, and there is an urgent need for a second-speed transport equipment that can realize turning

Embodiment 1

[0022] like figure 1 As shown, a second belt turning device includes a tail frame 2, several intermediate frames 3 and a head frame 6, an electric drum 7 is installed on the head frame 6, and a steering drum 1 is installed on the tail frame 2. Said middle frame 3 is composed of turning sub-frame 8 hinged connections, and the two ends of middle frame 3 are respectively hinged with nose frame 6 and tail frame 2; said turning sub-frame 8 has at least four articulated joints 81, respectively arranged on The upper and lower parts of the two ends of the turning subframe 8, the belt is installed on the electric drum 7 and the steering drum 1, the load and return belts are located in the turning subframe 8, and the belt roller 5 and the limit turning are set in the turning subframe 8. roll 4.

[0023] The structure to realize turning is on the hinged turning subframe. Due to the design of hinge points, each hinge point can realize a certain turning angle, and multiple turning subfram...

Embodiment 2

[0025] As a kind of technical scheme of embodiment 1, such as figure 2 , 3 As shown in , 4, the turning subframe 8 includes a frame body, and hinged joints 81 are arranged on the upper and lower parts of the end faces of both ends of the frame body.

[0026] The articulated joint 81 is two plugs 811 and two plugs 812, wherein the plug 811 is a plate with a hinge hole 813, the plug 812 is two plates with a hinge hole 813, and the two plates of the plug 812 are directly connected to each other. There is an insertion space for the plug board, which is hinged through the hinge hole 813 .

[0027] The hinge holes of the hinged joint 81 located on the upper plug and the lower plug are not on the same axis.

[0028] The hinge joint 81 is located at the center of the hinge hole of the upper plug and the center of the hinge hole of the lower plug, and the included angle between the end surface of the frame body is greater than 0° and less than 60°.

[0029] The included angle betwe...

Abstract

The invention discloses a second transfer belt turning device. The second transfer belt turning device comprises a tail rack, a plurality of middle racks and a head rack which are connected in sequence; an electric roller is installed on the head rack, a turning roller is installed on the tail rack, the middle racks are formed by hinging turning sub-racks, and the two ends of the middle racks arehinged to the head rack and the tail rack respectively; each turning sub-rack is provided with at least four hinging connectors which are arranged at the upper portions and the lower portions of the two ends of the turning sub-rack respectively; a belt is installed on the electric roller and the turning roller, and bearing and returning belts are located in the turning sub-racks; and belt carryingrollers and limiting turning rollers are arranged in the turning sub-racks. According to the second transfer belt turning device, by designing the hinging connectors, left and right free turning of the whole frame is achieved, the structure of the frame guarantees the normal operation of the belt in the whole device, and belt falling or tearing will not occur during turning.

Description

technical field [0001] The invention relates to a belt turning device for secondary transportation, which belongs to the technical field of mining equipment. Background technique [0002] The existing two-rotation transfer device includes steering drum, buffer bed, tail shoe, coal retaining curtain, hinge, travel hinge point, nose motorized roller, pulley device, etc. The steering drum adjusts the tightness and running deviation of the secondary transport belt; the electric drum of the machine head is the power part of the secondary transport, and a coal retaining curtain is set at the lower part of the coal hopper, and the tail slide shoe is grounded to unload the coal during the coal receiving and coal transporting process. flow force, and effectively slides and displaces on the floor as the power unit moves. The tail coal-bearing part and the middle frame part are hingedly connected. The middle frame is a steel frame structure. Lighting lamp holders and cable hooks are in...
