Embodiment 1

[0031] In this embodiment, the positioning mechanism of the telescopic arm is a positioning track 14 arranged horizontally. Through the setting of the positioning track 14, the telescopic arm 2 can be translated on the positioning track to increase the stability of the telescopic arm movement. A positioning hole is provided on the top, and when the telescopic arm 2 stretches out to a position convenient for this use, the pin is inserted into the positioning hole, and the fixing is completed, and the driving device 12 can be started. The driving device 12 of this embodiment is selected by hand. The rocking sprocket transmits power to the driving drum 11 through the sprocket to realize the overall operation of the equipment.

Embodiment 2

[0033] In this embodiment, the positioning mechanism of the telescopic arm is a positioning track 14 arranged horizontally. The positioning track 14 is hinged to the telescopic end, and the rear part is connected to a swing arm mechanism 4. The swing arm mechanism 4 is connected to the fixed frame 1, so that the positioning track 14 It can swing up and down along the hinge under the action of the swing arm mechanism 4. The swing arm mechanism 4 includes an oil cylinder and other fixtures such as a screw for fixing the action point of the oil cylinder to the positioning track 14 and the fixed frame 1. The telescopic arm 2 is provided with a rack 23 parallel to its axis, and the telescopic end is provided with a gear drive mechanism 5 matched with the rack. The gear drive mechanism 5 includes a drive motor 51, a sprocket combination 52, a gear shaft 53 and a gear 54 , the drive motor 51 drives the sprocket combination 52, the sprocket combination 52 drives the gear shaft 53, the ...

Embodiment 3

[0035] Such as figure 1 As shown, this embodiment is based on Embodiment 2. The telescopic arm 2 is a telescopic frame, which can reduce the weight of the telescopic arm 2, save materials, and facilitate the overall movement of the device. The conveyor belt 3 is a belt with low material cost, high transmission efficiency and light weight. The upper end surfaces of the fixed frame 1 and the telescopic frame are evenly distributed with supporting rollers 6, which can support the middle part of the belt, which is beneficial to improve the conveying quality and prolong the life of the belt. The supporting roller 6 adopts a V-shaped structure to ensure that earthwork or gravel can be transported in the middle of the belt by its own gravity to form a V-shaped groove, preventing earthwork or gravel from falling during belt transportation. The lower end surface of the fixed frame 1 is provided with a horizontal adjustment wheel 7, which can move the device more conveniently, and afte...

Abstract

The invention discloses a stretchable belt conveyor. The stretchable belt conveyor comprises a fixing frame, one end of the fixing frame is a fixed end provided with a driving roller, the driving roller is provided with a driving device, the other end of the fixing frame is a stretchable end provided with a stretchable arm positioning mechanism, the stretchable end is provided with a stretchable arm capable of reciprocating along the stretchable arm positioning mechanism, a front winding roller and a rear winding roller are arranged at the two ends of the stretchable arm correspondingly, an adjustable auxiliary roller is arranged on the inner side of the portion, below the stretchable arm, of the fixing frame, the driving roller, the front winding roller, the rear winding roller and the adjustable auxiliary roller are parallel to one another, and a closed-loop conveying belt which sequentially winds the driving roller, the front winding roller, the rear winding roller and the adjustable auxiliary roller is arranged. Through arrangement of the stretchable arm, the stretchable belt conveyor can adapt to roadway lengths of different specifications, is convenient to operate, can complete the working target without a tedious structure and redundant manpower, and is easy to manufacture, low in failure rate, safe, reliable, energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of extendable conveyors, in particular to an extendable belt conveyor. Background technique [0002] In the construction process of modern tunnel connecting passages, due to the fixed width of the roadway, suitable mechanical mining equipment cannot be used in the connecting passages, and most of them rely on manual excavation. In the early stage of construction, earthwork and gravel need to be transported out, and a large amount of building materials for strengthening the tunnel need to be transported in after construction. Traditional handling trolleys are labor-intensive, and as the depth of excavation increases, the cost of handling increases step by step. At this time, the transport plane is often used to assist the operation. [0003] However, with the deepening of excavation and the increase of the length of the connecting roadway, the existing belt conveyors cannot solve the problem of increasing t...
