Abstract
Description
Technical Field
[0001] This utility model relates to the field of tube conveying machine technology, and in particular to a tube conveying machine with anti-twist tubes. Background Technology
[0002] Pipe belt conveyors are used in a variety of industries, including steel, building materials, grain, salt production, and chemicals. They are used to transport purchased fuel (coal) in sintering, coking, and ironmaking processes. The unique advantages of pipe belt conveyors demonstrate their strong applicability.
[0003] A tubular belt conveyor is a longitudinally slit circular rubber tube that can self-close into a circular tube shape in the operating area, only unfolding into a planar conveyor in the receiving and unloading areas. While tubular belt conveyors have unique advantages, their complex structural design places relatively high demands on equipment maintenance. In particular, if the unfolded section of the conveyor belt deviates and twists, the problem is difficult to resolve. Therefore, this invention proposes a tubular belt conveyor with anti-twisting design. Utility Model Content
[0004] To solve the above technical problems, this utility model provides a pipe conveyor with anti-twisting function. When the pipe deviates from its designated path, a deviation switch is triggered to sound an alarm, preventing further pipe twisting.
[0005] The anti-twist tube conveyor in this solution includes an open section and a circular tube section connected together, and a support set above the open section. A slide block is horizontally slidably connected to the support, and a deviation switch is connected to the slide block. The sliding direction of the slide block is perpendicular to the conveying direction of the open section. The support is set close to the circular tube section so that the deviation switch is at the V-shaped tube section of the open section. A fastening bolt is also threadedly connected to the slide block, and the bottom of the fastening bolt abuts against the surface of the support.
[0006] Furthermore, it also includes a base with an inverted T-shaped groove, and the bottom of the bracket is provided with an inverted T-shaped support leg that is adapted to the inverted T-shaped groove. The displacement direction of the inverted T-shaped support leg in the inverted T-shaped groove is consistent with the conveying direction of the opening section.
[0007] Furthermore, the support frame is a gantry frame, and both the inverted T-shaped legs and the base are provided in twos.
[0008] Furthermore, the base is welded to the outer wall of the opening section.
[0009] Furthermore, the base is made of channel steel.
[0010] Furthermore, the support is a steel support.
[0011] The beneficial effects of this utility model are: This utility model provides a pipe conveyor with anti-twisting function. By sliding a deviation switch on the bracket, the position can be adjusted and fixed in the V-shaped opening section of the pipe conveyor. When the pipe deviates, the deviation switch is triggered to alarm, preventing further pipe twisting. At the same time, the front-to-back and left-to-right positions of the deviation switch are adjustable, which facilitates its debugging and assembly on the pipe conveyor and has wide applicability.

[0016] This embodiment provides a tube conveying machine for preventing tube twisting, such as... Figure 1 and Figure 2 As shown, the device has an open section 10 and a circular tube section 20 connected to each other. A steel bracket 31 is provided above the open section 10. A slide block 33 is slidably sleeved on the horizontal section of the bracket 31. A deviation switch 32 is connected to the slide block 33. The sliding direction of the slide block 33 is perpendicular to the conveying direction of the open section 10. The bracket 31 is positioned close to the circular tube section 20 so that the deviation switch 32 is located at the V-shaped section of the open section 10. A fastening bolt 34 is also threaded onto the slide block 33. The bottom of the fastening bolt 34 abuts against the surface of the bracket 31. When the fastening bolt 34 is tightened, the slide block 33 and the bracket 31 can be fixed relative to each other, and the deviation switch 32 is fixed in the horizontal direction.
[0017] See Figure 3 The anti-twist pipe conveyor also includes a base 36 with an inverted T-shaped groove 37. The base 36 is welded to the outer wall of the open section 10. In this embodiment, the base 36 is specifically made of channel steel. The bottom of the support 31 is provided with an inverted T-shaped support leg 35 that is adapted to the inverted T-shaped groove 37. The displacement direction of the inverted T-shaped support leg 35 in the inverted T-shaped groove 37 is consistent with the conveying direction of the open section 10.
[0018] In this embodiment, the bracket 31 is a gantry frame, and two inverted T-shaped legs 35 and two bases 36 are provided. The two bases 36 are symmetrically welded and arranged on the two outer walls of the opening section 10. In some other specific embodiments, the bracket 31 can also be an L-shaped design, requiring only one base 36 to be fixed on one outer wall of the opening section 10, so that when the slide 33 is displaced on the bracket 31, the deviation switch 32 can be located at the V-shaped tube of the opening section 10.
[0019] like Figure 1 As shown, in this utility model, when the pipe conveyor is in operation, the deviation switch 32 is located at the V-shaped pipe section of the pipe conveyor opening section 10. When one side of the pipe deviates, the deviation switch 32 is pressed and triggered to alarm, preventing further pipe twisting. At the same time, the position of the deviation switch 32 is adjustable in front and behind as well as left and right, which facilitates the installation, debugging and use of the deviation switch 32.
[0020] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
