Description

Technical Field

[0001] This utility model relates to the field of tubular conveyor belt installation technology, specifically a tubular conveyor belt laying and traction device. Background Technology

[0002] With increasingly stringent requirements for environmental protection and closed-loop transportation in the bulk material conveying sector, tubular belt conveyors have gained widespread application in industries such as power, mining, and ports due to their ability to achieve fully enclosed material transport, effectively preventing dust escape and material spillage. As the core component of this system, the tubular conveyor belt must be pulled through a closed tubular space composed of multiple sets of idlers during installation, replacement, or maintenance; this laying process is a crucial step in the engineering construction.

[0003] Currently, the traditional method for traction operations of tubular conveyor belts is to directly fix the belt ends with clamps and connect them to traction equipment via steel wire ropes. This method faces several challenges in practice: because the clamping points are concentrated on the outer side of the belt, the transmission path of the traction force is difficult to align with the belt's central axis, easily leading to belt twisting or deviation during traction; simultaneously, the rigid clamps and their exposed connecting components are prone to interference with the idlers when passing through the narrow space formed by the tubular idler roller assembly, causing jamming and affecting the smoothness of laying; furthermore, the localized pressure applied by the clamps to the belt is relatively high, posing a potential risk of damaging the belt's internal structure.

[0004] Therefore, the existing technology lacks a dedicated traction device that can adapt to the structural characteristics of tubular conveyor belts, achieve stable traction, and also protect the conveyor belts. This, to some extent, restricts the efficiency and reliability of the maintenance and installation of tubular conveyor systems. Utility Model Content

[0005] The present invention aims to solve the above problems and thus provide a tubular conveyor belt laying traction device to accelerate the laying efficiency.

[0006] The technical solution adopted by this utility model to solve the aforementioned problem is: A tubular conveyor belt laying traction device, comprising: A tubular support section, the outer diameter of which matches the inner diameter of the tubular conveyor belt to be laid, is used to be fitted onto the inner side of the end of the tubular conveyor belt. The traction assembly has one end of each of the two traction plates fixed to the upper and lower sides of the outer end of the tubular support, respectively, and the other ends of the two traction plates extend away from the tubular support and are connected to each other by a connecting rod. Fastening components are distributed along the axial and circumferential directions of the tubular support and are used to press and fix the tubular conveyor belt sleeved outside the tubular support. A traction sling is attached to the connecting rod, and the traction sling is configured to connect to an external traction power source after bypassing an external guide roller.

[0007] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: By providing internal support from the tubular support section and securing it with fastening components distributed circumferentially, the fastening force is distributed more evenly, reducing the risk of localized damage to the tape. The traction component forms a stable traction structure through traction plates and connecting rods connected to both sides of the tubular support section, allowing the point of application of the traction force to be closer to the central axis of the tubular tape. This helps guide the tape to move in a straight line, reducing the tendency for twisting or deviation during traction. At the same time, after being fixed, the traction device has a relatively regular external contour with no obvious protruding parts, which reduces the possibility of interference and jamming with the idlers when passing through the closed tubular space formed by the idlers, thus helping to ensure the smoothness of the laying process.

[0008] As a preferred embodiment, a further technical solution of this utility model is: Furthermore, the two traction plates are symmetrically arranged with respect to the central axis of the tubular support. This symmetrical arrangement allows for a more balanced distribution of traction force, further promoting the centering and stability of the traction process and preventing deflection caused by uneven force.

[0009] Furthermore, the tubular support has multiple sets of through holes along its axial direction on its tube wall, each set of through holes containing multiple mounting through holes evenly distributed circumferentially; the fastening assembly includes bolts passing through the mounting through holes, and the nuts of the bolts are housed in the inner cavity of the tubular support. This structure allows the fastening points to be evenly distributed circumferentially along the tape, thereby improving the uniformity of the fixing effect; the arrangement of accommodating the nuts in the inner cavity of the tubular support helps to keep the outer surface of the device flat and reduces the risk of snagging caused by protruding parts when passing through narrow spaces.

[0010] Furthermore, the traction plate and the tubular support are fixedly connected by welding. The welded connection provides high connection strength and structural rigidity, which helps to maintain the firmness and reliability of the connection between the traction assembly and the tubular support when subjected to large traction loads.

[0012] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0013] A tubular conveyor belt laying traction device, comprising: Tubular support part 1, which is a round tube, has an outer diameter that matches the inner diameter of the tubular conveyor belt 6 to be laid, and is used to be fitted onto the inner side of the end of the tubular conveyor belt 6. The traction assembly has two traction plates 2, one end of which is fixed to the upper and lower sides of the outer end of the tubular support 1, respectively. The traction plates 2 are V-shaped and the included angle of the traction plates 2 is obtuse. The other ends of the two traction plates 2 extend away from the tubular support 1. The sides of the two traction plates 2 away from the tubular support 1 are parallel to each other and are connected to each other by a connecting rod 3. The connecting rod 3 connects the ends of the two traction plates 2 away from the tubular support 1. Fastening components are distributed along the axial and circumferential directions of the tubular support 1 to press and fix the tubular conveyor belt 6 sleeved on the tubular support 1. A traction sling is connected to the connecting rod 3. The traction sling is configured to be able to bypass an external guide roller and connect to an external traction power source, which is a winch 5.

[0014] Furthermore, the two traction plates 2 are symmetrically arranged with respect to the central axis of the tubular support 1. This symmetrical arrangement can make the distribution of traction force more balanced, further promote the centering and stability of the traction process, and avoid deflection caused by uneven force.

[0015] Furthermore, the tubular support 1 has multiple sets of through holes along its axial direction on its tube wall, each set of through holes including multiple mounting through holes 4 evenly distributed circumferentially; the fastening assembly includes bolts passing through the mounting through holes 4, and the bolt nuts are housed in the inner cavity of the tubular support 1. This structure allows the fastening points to be evenly distributed circumferentially along the tape, thereby improving the uniformity of the fixing effect; the end of the tubular conveyor tape 6 is provided with a countersunk hole for the bolt to pass through, ensuring the integrity of the external surface. After the tape is laid, the end with the countersunk hole can be cut off. The arrangement of accommodating the nuts in the inner cavity of the tubular support 1 helps to keep the external surface of the device flat and reduces the risk of snagging caused by protruding parts when passing through narrow spaces.

[0016] Furthermore, the traction plate 2 and the tubular support 1 are fixedly connected by welding. The welded connection can provide high connection strength and structural rigidity, which helps to maintain the firmness and reliability of the connection between the traction assembly and the tubular support 1 when subjected to large traction loads.

[0017] During the laying of the tubular conveyor belt 6, the tubular support 1 is first inserted into the inner side of the end of the tubular conveyor belt 6 to be laid, so that its outer wall fits against the inner wall of the belt; then, the belt is tightened and fixed by fastening components distributed axially and circumferentially along the tubular support 1, wherein the bolts pass through the mounting through holes 4 opened on the wall of the tubular support 1 and the countersunk holes on the belt, and the nuts are housed in the inner cavity of the tubular support 1, so that the fastening force is evenly distributed along the circumference of the belt, keeping the outer contour of the device flat; next, the traction rigging is connected to the connecting rod 3 of the traction component, forming a symmetrical traction structure. This allows the point of application of the traction force to be closer to the central axis of the tubular conveyor belt. Finally, the traction sling passes around the external guide roller and connects to the external traction power source. The traction power source is activated, and the traction force is transmitted to the tubular support part 1 through the traction assembly, thereby driving the tubular conveyor belt 6 to move smoothly along its axial direction. This allows it to pass smoothly through the closed tubular space composed of multiple sets of idlers, effectively reducing the belt twisting, deviation, and interference and jamming between exposed parts and idlers caused by eccentric traction force in traditional traction methods, thus completing the laying of the tubular conveyor belt 6.

All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
