Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyor auxiliary technology, and in particular relates to a belt conveyor dragging device. Background Art

[0002] In existing technology, belt conveyors with long belt storage lengths and long take-up strokes require a towing device to tow the belt to prevent it from sagging. However, as the belt conveyor's operating conditions change, the required tension and take-up stroke vary. The towing device is susceptible to tipping due to the drag of the take-up trolley and the impact of the high-speed belt. Furthermore, high-speed belts are prone to deviation, and obstacles on the towing device's wheels, which are in direct contact with the guide rails, can affect the device's normal operation. Utility Model Content

[0003] The purpose of this utility model is to provide a belt conveyor towing device to address the above-mentioned shortcomings, so as to solve the problems of the existing towing device in the belt conveyor being prone to tipping over, belt deviation, or even separation from the rollers when the belt is running at high speed. In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions:

[0004] A belt conveyor towing device is arranged on the guide rails on both sides of the belt conveyor, and includes several towing trolleys; several of the towing trolleys are connected by chains; the towing trolleys include two brackets and a telescopic connection assembly; the two brackets are fixedly connected by the telescopic connection assembly; there are two detachable roller mounting assemblies on the brackets; the roller mounting assembly includes two roller mounting seats detachably connected to the two brackets; the roller mounting seats on the two side brackets are respectively used for mounting the two sides of the roller, and the angle of the roller relative to the guide rail can be adjusted.

[0005] Furthermore, the roller mounting seat includes a first connecting component; the first connecting component is detachably connected to the bracket; the first connecting component is provided with a plurality of grooves along the guide rail direction for mounting the roller; the two ends of the roller are respectively mounted on the grooves on the first connecting components on both sides.

[0006] Furthermore, the roller mounting seat also includes a second connecting component; the second connecting component is detachably connected to the first connecting component; and a stop roller is provided on the second connecting component.

[0007] Furthermore, the telescopic connection assembly includes steel sleeves fixed on two brackets respectively; a connecting rod with a diameter slightly smaller than the inner diameter of the steel sleeve is provided between the two steel sleeves; threaded holes are provided on the steel sleeves, and the connection is fixed by a set screw after adjusting the relative position.

[0008] Furthermore, the bracket is in an "in" shape; wheels are provided at the lower end of the bracket; and the wheels cooperate with the guide rails.

[0009] Furthermore, track-clearing steel plates are provided on the front and rear sides of the wheel along the guide rail direction; the track-clearing steel plates cover the front and rear sides of the wheel.

[0010] Furthermore, a steel wire rope is passed through the chain; the steel wire rope is in a stretched state and is used to support the chain.

[0011] Furthermore, the bracket is provided with a plurality of connection holes; the first connection component is correspondingly provided with threaded holes; the threaded holes on the first connection component are matched with the connection holes on the bracket and fixedly connected by bolts.

[0012] The beneficial effects of the utility model are:

[0013] 1. The belt conveyor towing device of the utility model can adjust the placement direction of the rollers according to the deviation direction of the belt. The roller at the end where the belt is deviating is placed in front. The rotation of the roller will bring an inward component of force to the belt, which can effectively correct the deviation of the belt and ensure the normal operation of the belt conveyor.

[0014] 2. The towing trolley structure in the belt conveyor towing device of the utility model is an "In" structure. When the tensioning stroke of the belt conveyor changes, the towing trolley is subjected to the dragging force of the tensioning trolley and the impact force of the belt running at high speed. It is more stable and not easy to tip over, thereby ensuring the normal operation of the belt conveyor.

[0015] 3. The bottom of the towing device bracket of the belt conveyor of the present invention is provided with four wheels. The bracket has an "In" structure and the spacing of the wheels on one side is separated as much as possible to ensure that the center of gravity of the towing device is between the two wheels, thereby enhancing the stability of the towing device operation. At the same time, track-clearing steel plates are provided in front and behind the wheels. When the towing device is moving, the bottom of the track-clearing steel plates is parallel to the guide rail with a small gap. The track-clearing steel plates in front and behind the wheels will clear obstacles on the guide rail to prevent the wheels from encountering obstacles, jumping the rails, or derailing, thereby ensuring the normal operation of the belt conveyor.

[0016] 4. The belt conveyor towing device of the utility model can adjust the distance between the two brackets and replace the roller group of corresponding length according to the bandwidth requirements, which can improve the versatility and practicality of the towing device, flexibly configure it, and reduce the variety of specifications.

[0017] 5. The towing trolleys in the belt conveyor towing device of the present invention are connected by chains, and a straight steel wire rope is inserted into the chain. When the distance between the towing trolleys is too close, the steel wire rope will support the chain to prevent the chain from sagging or rubbing against other equipment, thereby ensuring the normal operation of the belt conveyor.

[0026] Example:

[0027] like Figure 1-5As shown, a belt conveyor towing device is arranged on the guide rails 1 on both sides of the belt conveyor, and preferably includes three towing trolleys 13. Two adjacent towing trolleys 13 are connected by a chain 11. The characteristics of the chain 11 itself ensure that the towing trolleys 13 can move efficiently with each other. The towing trolley 13 includes two brackets 4, and the two brackets 4 are connected by a retractable component. The distance between the two brackets 4 can be adjusted to adapt to belt conveyors with different bandwidths. The bracket 4 is in the shape of an "In" character, and the triangular structure below it can improve its stability. When the towing trolley 13 is subjected to the vibration caused by the high-speed running belt 12, it is more stable and not easy to fall over. Two roller mounting assemblies are provided on the two brackets 4 for installing rollers 7. The two roller mounting assemblies are connected to the bracket 4 by a detachable structure, and the relative positions of the two rollers 7 can be adjusted. The roller installation assembly includes two roller 7 mounting seats detachably connected to the two brackets 4, which are in relative positions on the two brackets 4 to ensure that the plane where the installed rollers 7 are located is parallel to the plane where the two guide rails 1 are located. The roller 7 mounting seat includes a first connecting component 5 and a second connecting component 9. The two ends of the roller 7 are detachably connected to the bracket 4 through the first connecting component 5. The specific first connecting component 5 is a steel plate structure, which is provided with a threaded hole. There are multiple connecting holes corresponding to the threaded holes on the bracket 4, which are fastened by screws. The first connecting component 5 is preferably provided with three grooves for placing the rollers 7 side by side, which are arranged along the direction of the guide rail 1. When the tape 12 deviates, the roller 7 is placed at an angle, that is, the two ends of the roller 7 are respectively connected to the grooves at non-corresponding positions on the brackets 4 on both sides, as shown in the attached figure. Figure 4 As shown, the force F exerted by the inclined roller 7 on the belt 12 will not only exert force F1 along the running direction of the belt, but also cause the roller 7 to exert a horizontal component force F2 on the belt 12. The horizontal component force F2 will urge the belt 12 to move closer to the center of the roller 7, correcting the problem of the belt 12 running off. At the same time, a stop roller 10 is installed on the second connecting component 9. The height of the stop roller 10 is higher than that of the roller 7, which can prevent the belt 12 from suddenly running off sharply and running out of the range of the roller 7. The inclined placement of the roller 7 and the stop roller 10 provide a dual protection against the hidden danger of the belt 12 running off, ensuring the normal operation of the belt conveyor. The first connecting component 5 can be connected by aligning with the connection holes on the brackets 4 at different positions to achieve the function of adjusting the position of the roller 7. The first connecting component 5 and the second connecting component 9 are both steel plate structures, which can be detachably connected by setting threaded holes and fitting screws.

[0028] A steel wire rope 14 is passed through the chain 11. Both ends of the steel wire rope 14 can be fixed to the guide rail 1 through structures such as support rods, and the steel wire rope 14 is kept in a straight state. When the spacing between the towing trolleys 13 is less than the length of the chain 11, the steel wire rope 14 can support the chain 11 and will not sag, thereby ensuring the normal operation of the belt conveyor.

[0029] The towing trolley 13 runs on the guide rail 1 through the wheels 3 at the bottom of the bracket 4. A track cleaning steel plate 2 is installed at the position of the wheel 3. The bottom of the track cleaning steel plate 2 is parallel to the guide rail 1, and a small gap is left between the two. When the towing trolley 13 walks on the guide rail 1, the track cleaning steel plate 2 will clear the obstacles on the guide rail 1. The small gap between the bottom of the track cleaning steel plate 2 and the guide rail 1 ensures that the track cleaning steel plate 2 can effectively remove very small obstacles, avoiding the towing trolley 13 from encountering obstacles during the walking process, and preventing the wheels 3 from jumping or derailing, thereby ensuring the normal operation of the belt conveyor.

[0030] The retractable connection assembly specifically includes a connecting rod 6 and two steel sleeves. The two steel sleeves are respectively fixed on the two side brackets 4 and are on the same axis. The diameter of the connecting rod 6 is slightly smaller than the inner diameter of the steel sleeve and can be retracted in the steel sleeve. A threaded hole is provided on the steel sleeve along the axial direction, and a nut is welded at the position of the threaded hole. By adjusting the length of the connecting rod 6 finally displayed between the two steel sleeves, the distance between the two brackets 4 can be adjusted, and finally the fixation is completed by tightening the screw 8.
