Abstract
Description
Technical Field
[0001] The present invention relates to a conveying device, and in particular to a scraper conveyor. Background Art
[0002] A scraper conveyor is a conveying device that uses a scraper chain to tow and transport bulk materials in a scraper conveying trough. The solid structure is an important feature of the scraper conveyor. It can withstand external forces such as impact, collision, smashing, and pressing by coal, gangue, or other materials. However, this also brings corresponding problems, that is, its own weight is relatively heavy and it is inconvenient to move. Therefore, most scraper conveyors are fixedly installed in the conveying position and it is difficult to move flexibly to change the installation position. And in such non-fixed usage occasions that require flexible movement, the requirements for conveying distance, conveying height, etc. are often different. It is currently very difficult to use a single scraper conveyor to adapt to such changes in conveying distance or conveying height. In addition, when a scraper conveyor on the conveying line fails and requires a long time for maintenance, it will cause the shutdown of the conveying line. To resume transportation as soon as possible, it can only be immediately replaced with equipment of the same specification, but this is not realistic. It is not possible to have corresponding replacement spare parts for each specification of scraper conveyor. As long as there is a slight difference in parameters such as conveying distance or conveying height, it cannot be used for replacement, unless the scraper conveyor used for replacement can change the conveying height or conveying length within a certain range. However, as mentioned above, the current scraper conveyor cannot easily achieve this. Summary of the Invention
[0003] Aiming at the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an angle-adjustable and conveniently installed scraper conveyor, which can change the conveying height or conveying distance within a certain range and is convenient to move.
[0004] To solve the above technical problem, an angle-adjustable and conveniently installed scraper conveyor of the present invention includes a conveyor housing, a scraper chain running in the conveyor housing, a feed inlet and a discharge outlet. Sector-shaped support plates are fixedly provided on both sides of the conveyor housing at the input end. The sector-shaped support plates on both sides are coaxially arranged. The sector-shaped support plates are supported on a fixed base. An arc support surface in contact with the outer circular surface of the sector-shaped support plate is provided on the fixed base. A support plate position locking mechanism is provided between the fixed base and the sector-shaped support plate. The output end of the conveyor housing is supported on a support frame, and the support frame is a movable support frame with adjustable support height.
[0005] After adopting the above technical solution, the conveyor is rotatably supported on the fixed base by the sector-shaped support plates fixedly arranged on both sides of the input end of the conveyor housing, and then installed on the conveying site through the fixed base. In this way, the conveyor can rotate by an appropriate angle around the arc center of the sector-shaped support plates, and after the rotation angle is determined, the determined position is locked by the support plate position locking mechanism. Different rotation angles will change the height of the output end of the conveyor, and at the same time, the horizontal distance between the output end and the input end also changes accordingly. Correspondingly, the conveying height and conveying distance of the conveyor are changed accordingly, so as to achieve the purpose of changing the conveying height or conveying distance within a certain range. The output end of the conveyor housing is supported by a support frame that can adjust the height and move. Within the corresponding change range of the conveying height or conveying distance, the support frame can reliably support the output end of the conveyor housing by adjusting its support height and moving position, so as to ensure the stable operation of the conveyor under the working conditions of variable conveying height and conveying distance. At the same time, after the fixed base reaches the installation position, only need to unlock the support plate position locking mechanism, adjust the support height of the support frame, and then lock the corresponding position after the adjustment to carry out the conveying operation, making the installation and adjustment of this conveyor more convenient and fast.
[0006] In a preferred embodiment of the present invention, the height position of the axis of the sector-shaped support plate corresponds to the end face position of the feed inlet, and the front and rear positions of the axis of the sector-shaped support plate correspond to the center position in the front and rear directions of the feed inlet. By adopting this embodiment, the position of the feed inlet can be basically kept unchanged when the conveyor is adjusted to change the installation angle, and only the angle of the feed inlet changes accordingly, which can ensure the normal feeding. If the feed inlet is a rectangular opening along the length direction of the conveyor, the distance between the output end and the feed position can also be adjusted by changing the position of the input end of the conveyor, so as to further meet the requirement of changing the conveying distance.
[0007] In another preferred embodiment of the present invention, the support plate position locking mechanism includes a locking pin and a pin support fixed to the fixed base. There is a pin support hole on the pin support, and several pin holes are provided on the side surface of the sector-shaped support plate. Each pin hole is circumferentially evenly distributed on the same pin hole distribution arc line, and the center of the pin hole distribution arc line is located on the axis of the outer circular surface of the sector-shaped support plate. One end of the locking pin passes through the pin support hole and can be inserted into a pin hole. By adopting this embodiment, after the conveyor rotates by a certain angle around the arc center of the sector-shaped support plate, it is locked by the locking pin passing through the pin support hole and inserted into the corresponding pin hole. After the sector-shaped support plate is inserted and locked by the locking pin, it cannot rotate anymore, thus ensuring the fixation of its position. This support plate position locking mechanism has a simple structure and reliable positioning.
[0008] Another preferred embodiment of the present invention is that a plurality of pin supports are provided on the fixed base, and the pin supports are circumferentially and spaced apart along the circumferential direction of the arc supporting surface on the fixed base. With this embodiment, when the pin support holes on one pin support cannot be aligned with the pin holes at the angle position adjusted by the conveyor, the other pin supports with spaced distribution can be used to align with a pin hole and lock it, so that the height positions of the output ends corresponding to the angles that can be adjusted and locked have a smaller interval difference.
[0009] A further preferred embodiment of the present invention is that a support shaft is provided at the output end of the conveyor housing, and a corresponding support shaft seat is provided on the support frame. The output end of the conveyor housing is supported on the support frame through the support shaft and the support shaft seat. With this embodiment, the output end of the conveyor housing and the upper end of the support frame are hinged through the provided support shaft and support shaft seat, which can well meet the support requirements for the height change after the output end of the conveyor housing rotates around the arc center of the sector-shaped support plate.
[0010] Another further preferred embodiment of the present invention is that the support frame is a lift, and the support shaft seat is fixedly connected to the lifting platform of the lift. With this embodiment, using a lift as the support frame has strong versatility, can be directly purchased and used, and is convenient to move.
[0011] Another further preferred embodiment of the present invention is that a forklift slot is provided at the bottom of the fixed base. With this embodiment, a general forklift can be used to insert the forklift on it into the forklift slot at the bottom of the fixed base to move the position of the fixed base. Combining with the movable support at the output end of the lift, the conveyor can be conveniently moved to the required use position, better meeting the requirement that the conveyor is convenient to move.

Detailed implementation mode
[0017] In Figure 1 and Figure 2 In the angle-adjustable and conveniently-installable scraper conveyor shown, the conveyor housing 11 is a housing component with a rectangular cross-section. In the length direction of the conveyor housing 11, it can be straight or in a zigzag shape as shown in the figure. A scraper chain for conveying materials runs in the conveyor housing 11 and is driven by a scraper sprocket driven by a motor. The two scraper sprockets are respectively supported inside the housing at both ends of the conveyor housing 11. A feed inlet 5 is provided above one end of the conveyor housing 11, and a discharge outlet 15 is provided below the other end. The feed inlet 5 can be a circular feed port or a rectangular feed port. Using a rectangular feed port can adjust the installation position of the conveyor in the length direction so that the position of the discharge outlet 15 can be changed back and forth to meet the requirements of the discharge point position without affecting the feeding operation.
[0018] On both sides of the conveyor housing 11 at the input end where the feed inlet 5 is provided, sector support plates 1 are fixedly provided respectively. The sector support plates 1 are plate-shaped components approximately in the shape of a sector. The two sector support plates 1 on both sides are coaxially arranged. The height position of the axis of the sector support plate 1 corresponds to the height position of the end face of the feed inlet 5, and the front-back position of the axis of the sector support plate 1 corresponds to the center position of the feed inlet 5 in the front-back direction. The sector support plates 1 are supported on the fixed base 10, and an arc support surface 4 in contact with the outer circular surface of the sector support plate 1 is provided on the fixed base 10. The outer circular surface of the sector support plate 1 can rotate a certain angle on the arc support surface 4 on the fixed base 10.
[0019] A support plate position locking mechanism is provided between the fixed base 10 and the sector support plate 1. The preferred structure of the support plate position locking mechanism is as Figure 1 and Figure 2As shown in the figure, it includes a locking bolt 6 and a bolt support 7 fixedly connected to the fixed base 10. A plurality of bolt supports 7 are circumferentially spaced along the circumferential direction of the arc support surface 4 on the fixed base 10. Each bolt support 7 is provided with a bolt support hole 8. Of course, only one bolt support 6 can also be provided on each side. A plurality of bolt support holes 8 are provided on the bolt support 6 along the circumferential direction of the arc support surface 4 on the fixed base 10 at intervals. A number of bolt holes 2 are provided on the side surface of the sector-shaped support plate 1. Each bolt hole 2 is evenly distributed along the circumferential direction on the same bolt hole distribution arc line 3. The center of the bolt hole distribution arc line 3 is located on the axis of the outer circular surface of the sector-shaped support plate 1. One end of the locking bolt 6 passes through the bolt support hole 8 and can be inserted into a bolt hole 2, so that the sector-shaped support plate 1 can no longer rotate relative to the fixed base 10 and its position is locked; the central angle corresponding to the adjacent bolt support holes 8 circumferentially spaced along the arc support surface 4 on the fixed base 10 is not a multiple of the central angle corresponding to the adjacent two bolt holes 2. In this way, the sector-shaped support plate 1 can be rotated and locked at an angle smaller than the central angle corresponding to the adjacent two bolt holes 2 by inserting the positioning bolt 6 through different bolt support holes 8 and inserting it into the bolt hole 2, making the change interval of the conveying height at the output end smaller and better meeting the use requirements.
[0020] The output end of the conveyor housing 11 is supported on the support frame 14. The support frame 14 is a movable support frame with adjustable support height. One of its preferred support structures is as Figure 1 shown. A support shaft 12 is provided at the output end of the conveyor housing 11. The support shaft 12 is located at the inner end of the discharge port 15. The support shaft 12 can be rotatably supported below the conveyor housing 11 through bearings, or can be fixedly installed on the conveyor housing 11. A corresponding support shaft seat 13 for rotatably supporting the support shaft 12 is provided on the support frame 14. The output end of the conveyor housing 11 is hingedly supported on the support frame 14 through the support shaft 12 and the support shaft seat 12; the support frame 14 is preferably a general scissor lift, which can not only lift and lock the height, but also conveniently move the working position and lock the position where it is located after displacement. The support shaft seat 13 is fixedly connected to the lifting platform of the lift.
[0021] Figure 3 The figure shows a schematic diagram of two working positions of the scraper conveyor after adjusting the installation angle. In order to make the scraper conveyor move more conveniently, a forklift slot 9 is provided at the bottom of the fixed base 10. The forklift slot 9 can be arranged in the left-right direction or the front-back direction of the conveyor. In this way, a general manual or motorized forklift can use the forklift on it to insert into the forklift slot at the bottom of the fixed base to move the position of the fixed base. Cooperating with the movable support at the output end of the lift, the conveyor can be conveniently moved to the required use position.
[0022] The above only lists some preferred embodiments of the present invention, but the present invention is not limited thereto, and many improvements and transformations can also be made. As long as the improvements and transformations are made on the basis of the basic principles of the present invention, they shall be regarded as falling within the protection scope of the present invention.
