Description

Technical Field

[0001] This utility model belongs to the technical field of conveyor belt laying in transportation corridors, and specifically relates to an auxiliary device for laying conveyor belts in long-distance transportation corridors. Background Technology

[0002] Currently, belt conveyors (e.g., rubber belt conveyors) are commonly used to transport materials such as sand and gravel needed for dam construction. However, laying belt conveyors over long distances is a complex process. During construction, the volume and weight of the belt rolls necessitate the use of heavy-duty cranes for disassembly and stretching, resulting in wasted machinery. Furthermore, after one belt roll is stretched, it needs to be bonded to another, making it inconvenient for workers to disassemble and stretch the belt using heavy machinery. Additionally, the belt conveyor's roller frame has two layers, making the lower layer's belt laying process even more difficult and costly. Therefore, an auxiliary device for laying belt conveyors over long distances is needed to securely hold the belt and facilitate disassembly and stretching by construction workers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an auxiliary device for laying belts in long-distance transport corridors, addressing the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an auxiliary device for laying belts in long-distance transport corridors, characterized in that: it includes a placement bracket placed on one side of the belt conveyor roller frame and a winch placed on the other side of the belt conveyor roller frame. The placement bracket includes two triangular support frames and multiple connecting square steels for connecting the two triangular support frames. An installation plate is fixedly installed on the top of the triangular support frame. A limiting seat for limiting the front and rear positions of the rotating shaft is provided on the top of the installation plate. An arc bracket is provided inside the limiting seat and located at the lower part of the rotating shaft. A limiting bolt for limiting the up and down positions of the rotating shaft is provided on the upper part of the limiting seat. A belt roll is provided on the rotating shaft. The belt conveyor roller frame is a double-layer roller frame. The wire rope of the winch passes through the upper and lower layers of the double-layer roller frame and connects to the belt roll, splitting and stretching the belt roll onto the upper and lower layers of the roller frame.

[0005] The above-mentioned auxiliary device for laying belt conveyors in a long-distance transport corridor is characterized in that: a lifting plate for connecting a crane is installed on the triangular support frame.

[0006] The above-mentioned auxiliary device for laying belt conveyors in a long-distance transport corridor is characterized in that: the bottom of the mounting plate is connected to the triangular support frame through multiple reinforcing plates.

[0007] The above-mentioned auxiliary device for laying belt conveyors in a long-distance transport corridor is characterized in that: a platform for operators to walk on is provided on the outer side of the triangular support frame.

[0008] The above-mentioned auxiliary device for laying belts in long-distance transport corridors is characterized in that: the double-layer idler frame includes multiple portal frames, the multiple portal frames are connected by two connecting rods, lower idler rollers are installed on the portal frames, the multiple lower idler rollers form a lower idler frame, and multiple upper idler rollers are sequentially installed on the two connecting rods along the length direction, the multiple upper idler rollers form an upper idler frame.

[0009] The beneficial effects of this utility model are that it has a novel and reasonable design. The belt is fixed by a support bracket, and the belt roll is wound on the rotating shaft. The belt is pulled, and the rotating shaft rotates within the arc bracket. The limiting seat limits the front and rear positions of the rotating shaft, and the limiting bolt limits the vertical position of the rotating shaft. When a belt roll is unwound and stretched, the limiting bolt is removed, the empty rotating shaft is taken out, and a new belt roll with a rotating shaft is replaced. This can easily achieve the fixing, unwound, and stretched functions of the belt roll, which is safe and reliable. The wire rope of the winch passes through the upper and lower layers of the double-layer roller frame and connects to the belt roll. The belt roll is unwound and stretched onto the upper and lower roller frames, avoiding the waste of construction machinery resources caused by the use of large mechanical equipment, and is easy to promote and use.

[0021] like Figures 1 to 3As shown, this utility model includes a placement bracket placed on one side of the conveyor roller frame and a winch 15 placed on the other side of the conveyor roller frame. The placement bracket includes two triangular support frames 1 and multiple connecting square steel bars 10 for connecting the two triangular support frames 1. A mounting plate 4 is fixedly installed on the top of the triangular support frame 1. A limiting seat 5 for limiting the front and rear positions of the rotating shaft 6 is installed on the top of the mounting plate 4. An arc bracket 8 is installed inside the limiting seat 5 and located at the lower part of the rotating shaft 6. A limiting bolt 7 for limiting the up and down positions of the rotating shaft 6 is installed on the upper part of the limiting seat 5. A belt roll 17 is installed on the rotating shaft 6. The conveyor roller frame is a double-layer roller frame. The wire rope 16 of the winch 15 passes through the upper and lower layers of the double-layer roller frame and connects to the belt roll 17, splitting and stretching the belt roll 17 onto the upper and lower layers of the roller frame.

[0022] It should be noted that the belt is fixed in place using a support bracket, and the belt roll is wound around the shaft. The belt is pulled, and the shaft rotates within the arc bracket. The limit seat limits the front and rear positions of the shaft, and the limit bolt limits the vertical position of the shaft. When a belt roll is unwound and stretched, the limit bolt is removed, the empty shaft is taken out, and a new belt roll with a shaft is replaced. This method can easily achieve the fixing, unwound, and stretching of the belt roll, which is safe and reliable. The wire rope of the winch passes through the upper and lower layers of the double-layer roller frame and connects to the belt roll. The belt roll is unwound and stretched onto the upper and lower roller frames, avoiding the waste of construction machinery resources caused by the use of large mechanical equipment.

[0023] In this embodiment, a lifting plate 2 for connecting a crane is installed on the triangular support frame 1.

[0024] It should be noted that the purpose of installing the lifting plate 2 on the triangular support frame 1 for connecting the crane is to facilitate the overall lifting and handling of the support frame.

[0025] In this embodiment, the bottom of the mounting plate 4 is connected to the triangular support frame 1 through multiple reinforcing plates 9.

[0026] It should be noted that the bottom of the mounting plate 4 is connected to the triangular support frame 1 by multiple reinforcing plates 9, making the mounting plate 4 more stable and ensuring high safety in use.

[0027] In this embodiment, a platform 3 for operators to walk on is provided on the outer side of the triangular support frame 1.

[0028] It should be noted that a platform 3 for operators to walk on is provided on the outside of the triangular support frame 1, which facilitates the construction personnel to perform auxiliary operations such as belt disassembly and stretching.

[0029] In this embodiment, the double-layer idler frame includes multiple portal frames 11, which are connected by two connecting rods 12. Lower idler rollers 13 are installed on the portal frames 11, and the multiple lower idler rollers 13 form the lower idler frame. Multiple upper idler rollers 14 are sequentially installed on the two connecting rods 12 along the length direction, and the multiple upper idler rollers 14 form the upper idler frame.

[0030] In use, the belts on the upper or lower idler frames are laid in any order. During the laying process, the belts in the belt reels face different directions. After the belts on both the upper and lower idler frames are laid, they are connected using adhesive bonding technology to form a closed belt conveyor system. When laying the upper belt, the wire rope 16 of the winch 15 passes through the upper idler frame of the double-layer idler frame and connects to the belt reel 17. When laying the lower belt, the wire rope 16 of the winch 15 passes through the area between the upper and lower idler frames of the double-layer idler frame, i.e., the wire rope 16 is positioned above the lower idler frame and below the upper idler frame. The belt roll 17 is connected to the hoist. When the belt roll 17 is stretched by the winch, it slides along the idler frame. The traction process is safe and reliable. When laying the upper or lower layer belt, a belt roll is installed on the limit seat 5 on the two triangular support frames 1 and fixed by the limit bolt 7. The belt roll 17 is stretched by the winch. After the belt roll is stretched and split, the limit bolt is removed, the idle shaft is taken out, and a new belt roll with a shaft is replaced. The new belt roll with a shaft is connected to the previous belt roll by adhesive bonding. This reduces the tedious layout and positioning work, shortens the construction cycle, saves costs, and can easily achieve the fixing, splitting and stretching of the belt roll. It is safe and reliable.

[0031] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
