Description

Technical Field

[0001] The utility model relates to the technical field of transmission, in particular to a foldable frame device for a belt conveyor. Background Art

[0002] Belt conveyor is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of a frame, conveyor belt, rollers, drums, tensioning devices, transmission devices, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can convey both bulk materials and pieced items. In addition to pure material conveying, it can also cooperate with the requirements of the process in the production process of various industrial enterprises to form a rhythmic flow operation transportation line.

[0003] After searching, it was found that the patent disclosed "a folding frame device for a belt conveyor", and its application number is "201921326240.5". The patent mainly includes two parallel rails: multiple frames, the frame at the head end is fixedly connected to the rail, and each of the other frames is provided with a frame support seat on both sides of the lower end, and the frame support seat is slidably supported on the corresponding rail; multiple frames are spaced apart from each other in the extension direction of the rail, and wire rope hooks are provided on the frames at the tail end and the head end; a connecting rod mechanism is provided between adjacent frames, and the connecting rod mechanism includes two middle rods and four side rods, the two middle rods are hinged to each other in the middle, and the two ends of the middle rods are connected to the adjacent frames through the corresponding side rods. The folding frame device of the utility model can quickly adjust the length to adapt to the adjustment of the belt length, and can move as a whole, so the adjustment efficiency is high, and it can well adapt to the requirements of overall position adjustment.

[0004] However, although the above patent can quickly adjust the length to adapt to the adjustment of the belt length, and can move as a whole, so the adjustment efficiency is high, and it can well adapt to the requirements of overall position adjustment, but after the adjustment, there is a lack of locking mechanism between the semicircular sliding sleeve and the rail, which causes the semicircular sliding sleeve to slide on the outer wall of the rail easily during use, thereby driving the upper end of the frame to move, affecting the normal use of the conveyor belt. Therefore, we propose a folding frame device for a belt conveyor to solve the above problems. Utility Model Content

[0017] The utility model has the following beneficial effects:

[0018] 1. Compared with the prior art, the foldable frame device for the belt conveyor has a locking component. When the length adjustment is completed, the hand wheel drives the worm to rotate, and the worm drives the multiple shafts to rotate through the multiple worm gears. The multiple shafts drive the multiple gears to rotate. The multiple gears make the multiple racks meshing with each other move horizontally, so that the multiple racks push the locking plate to slide horizontally inside the slide groove through the multiple vertical rods. In this process, the locking plate drives the multiple limit blocks to slide inside the multiple limit grooves, and the anti-slip pad of the outer wall of the locking plate will contact with the U The inner walls of the U-shaped slide seats abut against each other, and the interlocking function of the worm gear and the worm is utilized to lock multiple U-shaped slide seats to the outer wall of the track. Compared with the existing device, there is a lack of locking mechanism between the semicircular slide sleeve and the track after adjustment, which causes the semicircular slide sleeve to slide easily on the outer wall of the track during use, thereby driving the upper end frame to move, affecting the normal use of the conveyor belt. The device can lock multiple U-shaped slide seats after adjusting the length to the outer wall of the track, avoiding multiple U-shaped slide seats from sliding on the outer wall of the track during use, thereby fixing the upper end frame and facilitating the use of the conveyor belt.

[0019] 2. Compared with the prior art, the foldable frame device for the belt conveyor, through the set frame parts, horizontally pulls the frames at the head and tail ends according to the length of the conveyor belt, so that the frames at the head and tail ends respectively drive the U-shaped slide below to slide horizontally away on the outer wall of the track, and under the action of multiple connecting rod assemblies, drives multiple frames to expand and move horizontally in turn, so that the conveyor belt rollers at the upper end of the frame are matched with the conveyor belt. The device can adjust the distance between the multiple frames according to the length of the conveyor belt, so that the conveyor belt rollers are more adapted to the length of the conveyor belt, thereby improving the overall adaptability.
