Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to a bracket for a conveyor belt mechanism and a cable conveyor belt system. Background Art

[0002] In the prior art, technicians would use a truss conveyor belt mechanism to transport some bulk materials such as coal or ore over long distances. The truss conveyor belt mechanism is a structural form that combines a conveyor belt with a steel structure truss, which is similar to the pipe conveyor structure disclosed in the patent document with the authorization announcement number CN208790446U and the authorization announcement date of 2019.04.26. This type of truss conveyor belt mechanism has a short span and is difficult to meet the construction requirements of facilities such as crossing mountainous areas, rivers, and railways. In addition, the erection of the truss structure requires a large number of supports for support, which is costly and difficult to install.

[0003] With the development of technology, technicians have proposed a method of combining a cable structure with a conveyor belt to transport bulk materials over a large span. For example, a cable tube belt conveying structure disclosed in a patent application document with application publication number CN109018829A and application publication date 2018.12.18, includes four cables arranged in parallel, two cables arranged at the top, which are upper cables, and two cables arranged at the bottom, which are lower cables. The connecting line between adjacent cables is rectangular. The conveying structure also includes a bracket fixed on the cable, and a plurality of brackets are provided, and are arranged at intervals along the extension direction of the cable. Rollers are rotatably mounted in the bracket, and the movement direction of the conveyor belt is the same as the extension direction of the cable, and the conveyor belt is arranged in the bracket, and the conveyor belt can roll with the rollers. The cable, conveyor belt and bracket are combined to form a conveyor belt mechanism.

[0004] In the transport system for transporting bulk materials, in addition to the above-mentioned conveyor belt mechanism, a pillar is also provided to support the conveyor belt mechanism, and the conveyor belt mechanism is arranged on the top of the pillar. In order to inspect the operating status of the conveyor belt mechanism, the technicians also configure an inspection mechanism, which includes an inspection cable car. A traction cable that cooperates with the inspection cable car is installed on the top of the pillar, which can drive the inspection cable car to move. The operator can directly observe the operating status of the conveying structure along the line on the inspection cable car, and can also set a monitoring element on the inspection cable car to monitor the operating status of the conveying structure along the line.

[0005] The cable tube conveyor structure uses cables to solve the problem of short span of the truss structure, but it still has the following defects:

[0006] 1) Since the cables are installed on the top of the columns, the height of the columns is high, the more cables are arranged, the more difficult it is to install. At the same time, the length of the cables is long, and increasing the number of cables will increase the production cost accordingly;

[0007] 2) There are four cables in the cable tube conveyor structure, and they are arranged in a way that their axes correspond to the four corner vertices of a rectangle. The bracket is a polygon with the number of sides corresponding to the number of cables, that is, a rectangle. The cables are supported in the air by columns and are easily affected by strong winds and other factors and swing. The rectangular frame may deform and fail during the swinging of the cables, and the stability and safety of the cable tube conveyor structure are poor. Summary of the invention

[0008] The object of the present invention is to provide a bracket for a conveyor belt mechanism, which can solve the problems of high cost, poor stability and safety caused by the use of rectangular brackets in the prior art; another object of the present invention is to provide a cable conveyor belt system, which has the advantages of low cost and stable operation.

[0009] In order to achieve the above-mentioned purpose, the support for the conveyor belt mechanism in the present invention adopts the following technical solution:

[0013] The main frame is in a triangular shape, and fixing parts for fixing connection with cables are arranged at the positions of the three vertices of the main frame corresponding to the triangle.

[0014] The beneficial effect is that the main frame of the bracket is triangular, which can utilize the stability of the triangle to reduce the possibility of failure of the bracket due to swinging deformation. At the same time, due to the use of a triangular bracket, only three cables are required in the system, which can reduce the investment in cables and reduce production and operation and maintenance costs.

[0015] Furthermore, the outline of the main frame is an isosceles triangle, and the main frame includes a bottom beam corresponding to the base of the isosceles triangle. Both ends of the bottom beam are provided with extension sections extending to both sides of the main frame, and the extension sections are provided with the fixing parts.

[0016] Its beneficial effects are: an extension section extending to both sides of the main frame is provided on the bottom beam, the extension section is formed by the extension of the bottom beam, and can provide sufficient space for the arrangement of the fixing parts. The operator does not have to arrange the fixing parts in the main frame, thereby simplifying the structure of the bracket.

[0017] Furthermore, a supporting crossbeam is provided in the main frame, and the supporting crossbeam is provided at a middle position in the height direction of the main frame, so as to enhance the deformation resistance of the main frame.

[0018] The beneficial effect is that a supporting crossbeam is arranged in the main frame, and the supporting crossbeam can improve the deformation resistance of the main frame and ensure the stability of the bracket when in use.

[0019] Furthermore, the supporting cross beam is a straight beam extending in the horizontal direction, or is an arc-shaped beam, and the arc-shaped beam protrudes toward the top corner of the main frame.

[0034] There are two inspection platforms, which are located at both ends of the crossbeam; the interval between the two inspection platforms constitutes an escape space for the conveyor belt mechanism of the cable conveyor belt system;

[0035] The upper anti-skew wheel is rotatably mounted on the crossbeam or the upper part of the two maintenance platforms. A roller track is arranged on the wheel surface of the upper anti-skew wheel, and rollingly cooperates with the upper cable among the three cables fixedly connected to the main frame;

[0044] A supporting crossbeam is arranged in the main frame, which can improve the anti-deformation ability of the main frame and ensure the stability of the bracket when in use. At the same time, a straight beam or an arc beam is adopted, which has a simple structure and is easy to assemble while being able to improve the anti-deformation ability.

[0070] The features and performances of the cable conveyor belt system and the bracket for the conveyor belt mechanism of the present invention are further described in detail below in conjunction with the embodiments.

[0071] Embodiment 1 of the cable conveyor belt system of the present invention: Figure 1 As shown, the cable conveyor belt system of the present invention comprises a steel structure pillar 11, which is fixed on the ground and has a certain height. The cable conveyor belt system also comprises a conveyor belt mechanism, which is fixed on the top of the pillar.

[0072] The conveyor belt mechanism includes cables 90, brackets 70, and a conveyor belt located inside the cables 90 and brackets 70. In this embodiment, three cables 90 are arranged in parallel, and the three cables 90 are arranged in a manner that their axes correspond to the three vertices of a triangle.

[0073] A plurality of brackets 70 are arranged along the extension direction of the cable, and each bracket 70 is fixedly connected to the cable; rollers are arranged on the bracket 70, and there is space inside for installing a conveyor belt.

[0074] The cable conveyor belt system also includes a traction cable 12, which is installed on the top of the pillar 11 and above each cable 90. A maintenance cable car 13 is suspended on the traction cable 12. The maintenance cable car 13 is equipped with components for corresponding to the traction cables 12 and cables 90 in the cable conveyor belt system, so that the maintenance cable car 13 can move along the extension direction of the traction cables 12 and cables 90 in the cable conveyor belt system. The operator can use the maintenance cable car 13 to observe the situation along the cable conveyor belt system, and maintain and repair the system.

[0075] The specific structure of the conveyor belt mechanism and its relative relationship with the maintenance cable car are now described in detail.

[0076] like Figure 2 , Figure 3 and Figure 4 As shown, the maintenance cable car 13 includes a top crossbeam 10 extending in the left and right directions in the figure, and the upper surface of the top crossbeam 10 is provided with a cable locking portion 40 for cooperating with the traction cable 12 in the cable conveyor belt system. The cable locking portion 40 can be locked with the traction cable 12 to fix the maintenance cable car 13 relatively to the traction cable 12, and the traction cable 12 can drive the maintenance cable car 13 to move when it is transmitted.

[0077] An inspection platform is hoisted at both ends of the top crossbeam 10. The inspection platform is a frame structure. When the inspection cable car is moving, the operator can stand on the inspection platform to observe the operation of the conveyor belt. There are two inspection platforms in this embodiment, namely a left inspection platform 20 and a right inspection platform 30. The two inspection platforms are arranged on the left and right sides of the conveyor belt 83.

[0078] A left inclined beam 21 is arranged on the side of the left maintenance platform 20 facing the right maintenance platform 30, and the right end of the left inclined beam 21 is higher than the left end, so that the side of the left maintenance platform 20 facing the right maintenance platform 30 is an inclined surface.

[0079] A right inclined beam 31 is arranged on the side of the right maintenance platform 30 facing the left maintenance platform 20, and the left end of the right inclined beam 31 is higher than the right end, so that the side of the right maintenance platform 30 facing the left maintenance platform 20 is an inclined surface.

[0080] The sides of the left maintenance platform 20 and the right maintenance platform 30 facing the avoidance space are inclined, so that the space between the two maintenance platforms is in an inverted V shape. The conveyor belt mechanism in the cable conveyor belt system can avoid the cable 90, the bracket 70 and the conveyor belt 83 in this inverted V-shaped space when the maintenance cable car 13 moves.

[0081] In order to ensure the stability of the maintenance cable car during operation, an anti-skew wheel is installed on the cable car body to cooperate with the cable 90 in the cable conveyor belt system. In this embodiment, the anti-skew wheel is divided into an upper anti-skew wheel 50 and a lower anti-skew wheel 60. The upper anti-skew wheel 50 has a group and is arranged at the middle position of the lower surface of the top cross beam 10.

[0082] Specifically, a wheel seat 52 is provided on the lower surface of the top cross beam 10, and a roller 51 is rotatably mounted in the wheel seat 52. The wheel seat 52 is composed of two vertical plates arranged at intervals in the horizontal direction, the plate surfaces of the two vertical plates extend in the up-down direction, and a space for installing the roller 51 is reserved between the two vertical plates. A through hole is provided on the vertical plate along the extension direction of the top cross beam 10 for the shaft to pass through. The roller 51 is rotatably mounted on the wheel seat 52 through the shaft passing through the through hole. At this time, the rotation axis of the upper anti-skewness wheel 50 extends in the horizontal direction and is parallel to the extension direction of the top cross beam 10.

[0083] The wheel surface of the roller 51 is provided with a rolling track matching the shape of the cable 90, which can roll with the cable 90 to guide the movement of the maintenance cable car. In other embodiments, the upper anti-skew wheel 50 can also be arranged on the front or rear side of the top cross beam 10, and is not limited to the scheme of arranging the upper anti-skew wheel 50 only on the bottom surface of the top cross beam 10.

[0084] The lower layer anti-skew wheels 60 are arranged in two groups, which are respectively arranged on the bottom surfaces of the left maintenance platform 20 and the right maintenance platform 30. That is, a wheel seat 62 is arranged on the bottom surfaces of the two maintenance platforms, and a roller 61 is rotatably mounted in the wheel seat 62.

[0085] The wheel seat 62 is composed of two vertical plates arranged at intervals along the horizontal direction. The plate surfaces of the two vertical plates extend along the up and down directions, and a space is reserved between the two vertical plates for installing the roller 61. The vertical plates are provided with through holes arranged along the extension direction of the top cross beam 10 for the rotation shaft to pass through. The roller 61 is rotatably assembled on the wheel seat 62 by the rotation shaft passing through the through holes. At this time, the rotation axis of the upper anti-skewness wheel 60 extends along the horizontal direction and is parallel to the extension direction of the top cross beam 10.

[0086] The wheel surface of the roller 61 is provided with a rolling track matching the shape of the cable 90, and can roll with the cable 90. The movement of the maintenance cable car is guided.

[0087] The upper anti-skew wheel 50 and the lower anti-skew wheel 60 are arranged in a manner corresponding to the three vertices of the triangle, so that the upper and lower parts of the maintenance cable car can cooperate with the corresponding cable 90 guide, ensuring the stability of the maintenance cable car when it is running at high altitude. In this embodiment, only one anti-skew wheel is provided in the upper anti-skew wheel 50 and the lower anti-skew wheel 60. In other embodiments, the number of anti-skew wheels can be adjusted according to the size of the maintenance cable car, and is not limited to the solution of using only one anti-skew wheel.

[0088] For example Figure 3 As shown, when the maintenance cable car is used in conjunction with the conveyor belt and the cable 90, three cables 90 are arranged in the cable conveyor belt system, and the three cables 90 are arranged in such a way that their respective axes correspond to the three vertices of a triangle.

[0089] like Figure 4 As shown, the bracket 70 in this embodiment includes a main frame in the shape of an isosceles triangle, and the main frame includes side beams 701 constituting two waists of the isosceles triangle, and a bottom beam 702 constituting the bottom side of the isosceles triangle. Inside the main frame, at the middle position in the height direction, i.e., the up-down direction, a straight support beam 703 is provided, and the two ends of the support beam 703 are respectively connected to the side beam 701 to improve the rigidity and strength of the bracket 70 and enhance the anti-deformation ability of the bracket 70. In other embodiments, the support beam may not be provided in the main frame.

[0090] At the intersection of the two side beams 701, that is, at the top vertex position of the bracket 70, a fixing piece 704 fixedly connected to the cable 90 is provided, and the fixing piece 704 here is arranged upward. The two ends of the bottom beam 702 are provided with extension sections 7021 extending outward over the two side beams 701, and the upper surface of the extension section 7021 is provided with a fixing piece 704 arranged upward, which is fixedly connected to the two lower cables of the three cables. In other embodiments, the main frame of the bracket 70 forms a closed triangular structure, and no extension section is provided on the side beam or the bottom beam. In this case, the main frame can adopt an equilateral triangle structure or a triangle with unequal side lengths. A detection element 705 is also fixed on the supporting crossbeam 703, which can monitor the condition of the bulk material on the conveyor belt 83. The space between the supporting cross beam 703 and the bottom beam 702 is a conveyor belt avoidance space for avoiding the conveyor belt 83. A Japanese-shaped fixing frame is also arranged in the space, and a roller group that rolls with the conveyor belt 83 is rotatably mounted on the fixing frame.

[0091] The roller group is divided into an upper roller group 81 and a lower tubular roller group 82. In this embodiment, the upper roller group 81 and the lower tubular roller group 82 have the same structure as the process roller group and the return roller group disclosed in the patent application document with application publication number CN109018829A and application publication date 2018.12.18, and are all enclosed in a tubular shape. The conveyor belt 83 located on the roller group also forms a tubular conveyor belt. Due to the closed characteristics of the tubular conveyor belt, there is no spillage and dust when transporting bulk materials, which is more environmentally friendly.

[0092] The upper anti-skew wheel 50 on the maintenance cable car rolls with one of the three cables 90 located at the upper part, and the lower anti-skew wheel 60 rolls with two of the three cables 90 located at the lower part. At this time, the bottom surface of the maintenance cable car 13 is located above the bottom beam 702 of the bracket 70, and the fixing member 704 on the bottom beam 702 is directly opposite to the lower anti-skew wheel 60 on the bottom surface of the two maintenance platforms in the up and down direction. In the cable conveyor belt system, a traction cable 12 is arranged above the cable 90, and the cable locking part 40 of the maintenance cable car 13 is hooked and locked on the traction cable 12, and the traction cable 12 drives the maintenance cable car 13 to move forward.

[0093] Embodiment 2 of the cable conveyor belt system of the present invention is different from the above-mentioned embodiment in that: Figure 5 As shown, the left maintenance platform 20 and the right maintenance platform 30 in this embodiment are facing the side of the avoidance space and are planes extending along the vertical direction. The space between the two maintenance platforms below the top cross beam is a U-shaped space, and the triangular bracket 70 is arranged in the U-shaped space.

[0094] A cable locking portion 40 for locking with the traction cable is fixed on the upper surface of the top cross beam 10, and a wheel seat is fixed on the lower surface of the top cross beam 10. A roller 51 is rotatably mounted in the wheel seat to serve as an upper anti-skew wheel and roll with the corresponding cable 90. Wheel seats are also provided on the bottom surfaces of the two maintenance platforms. Rollers 61 are rotatably mounted in the wheel seat to serve as a lower anti-skew wheel and roll with the corresponding cable 90.

[0095] Embodiment 3 of the cable conveyor belt system of the present invention is different from the above embodiments in that: Figure 6 As shown, in this embodiment, an inverted V-shaped space is enclosed between the left maintenance platform 20 and the right maintenance platform 30, and a triangular bracket 70 having the same bracket structure as in Embodiments 1 and 2 is arranged in the inverted V-shaped space, and the three vertices of the triangular bracket 70 are respectively fixed to the three cables 90 in the system.

[0096] A cable locking portion 40 that locks with the traction cable is fixed to the upper surface of the top crossbeam 10 , and a wheel seat is fixed to the lower surface of the top crossbeam 10 , in which a roller 51 is rotatably mounted to serve as an upper anti-skew wheel to roll with the corresponding cable 90 .

[0097] Wheel seats are also provided on the bottom surfaces of the two inspection platforms, and rollers 61 are rotatably mounted in the wheel seats to serve as lower anti-skew wheels and to roll with the corresponding cables 90 .

[0098] In the triangular support 70, an upper roller group and a lower roller group are arranged, wherein the rollers in the upper roller group are arranged in a U-shape, namely a U-shaped roller group 84, and the forward portion of the conveyor belt 83 is also surrounded in a U-shape. The rollers in the lower roller group are arranged in a V-shape, namely a V-shaped roller group 85, and the return portion of the conveyor belt 83 is surrounded in a V-shape. In order to ensure the strength of the support, the crossbeam in the support 70 is an arc beam.
