Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, specifically a high-capacity head and tail dual-drive reversible distribution belt conveyor. Background Technology

[0002] In industries such as coal, steel, and chemicals, a common method for distributing materials across multiple silos is using reversible belt conveyors. Due to height limitations above the silos, reversible belt conveyors typically employ a linear arrangement with a single head drive and a tail helical tensioner (this method is the most space-efficient; using intermediate tensioning or adding an intermediate drive requires increasing the height of the belt conveyor, which is not feasible in some mining conditions). When using this arrangement for long-distance, high-volume material distribution, insufficient belt tension at the tail pulley can cause slippage, affecting production and operation. This problem arises because the helical tensioner's tension is limited. When the conveyor reverses direction towards the tail, the carrying surface becomes the return surface, and the tension at the tail pulley's approach point decreases. In situations requiring long distances and large volumes, the insufficient belt tension at the tail pulley in this configuration leads to slippage and operational issues. A dual-drive arrangement at both the head and tail ends conflicts with the drive mechanism, making it difficult to implement.

[0003] One way to solve the spatial interference problem between the tail drive unit and the tensioning device in a dual-drive layout is to use an internal electric roller. While this solves the space arrangement problem with the tensioning device, the internal electric roller typically has lower power and poor heat dissipation. Under long-term, high-volume delivery conditions, it often malfunctions due to prolonged overload operation, affecting production. Therefore, the dual-drive structure with an internal electric roller is also insufficient for meeting the demands of long-distance, high-volume reversible distribution. Utility Model Content

[0031] Example 1

[0032] Reference Figures 1-5 This embodiment provides a high-capacity head-and-tail dual-drive reversible distribution belt conveyor, including a frame 100, a head drive component 200 at one end of the frame 100, a tension trolley 300 at the other end of the frame 100, and a tail tension component 400 at the other end of the frame 100, which is connected to the tension trolley 300; a first roller 101 and a second roller 102 are provided on the frame 100, and a belt 103 is connected between the first roller 101 and the second roller 102; the head drive component 200 is connected to the first roller 101; and the tension trolley 300 is provided with a tail drive component 500, which is connected to the second roller 102.

[0033] The first roller 101, the second roller 102, and the belt 103 together form a conveying component. The first roller 101 is located at the head and is driven to rotate by the head drive component 200. The second roller 102 is located at the tail and is driven to rotate by the tail drive component 500. Together, they form a belt conveyor with dual head and tail drives.

[0034] In this application, a tensioning carriage 300 is provided at the tail of the frame. The tail drive component 500 and the second roller 102 are both mounted on the tensioning carriage 300. The tensioning carriage 300 moves under the control of the tail tension component 400 to achieve the tensioning effect on the belt 103, while not affecting the driving function of the tail drive component 500 on the second roller 102.

[0035] A fixed guide rail 104 is provided at the tail of the frame 100, and support blocks 102a are provided at both ends of the second roller 102. The support blocks 102a are provided on the fixed guide rail 104.

[0036] The fixed guide rail 104 is fixed to the frame 100 as a whole.

[0037] It should be noted that the intermediate shaft of the second roller 102 is connected to the support block 102a through a bearing, and the support block 102a can slide on the fixed guide rail 104.

[0038] It should be noted that the bottom of the support block 102a can also be equipped with rollers that connect to the fixed guide rail 104 so that the support block 102a can move on the fixed guide rail 104.

[0039] The tensioning trolley 300 includes a crossbar 301, a roller 302 disposed at the bottom of the crossbar 301, and a connecting rod 303 connected to the support block 102a. The roller 302 is disposed on the fixed guide rail 104.

[0040] It should be noted that, Figure 5 The tail drive unit 500 and crossbar 301 are omitted from the display.

[0041] The tail tensioner 400 includes a lead screw 402 fixed to the side of the frame 100 via a side plate 401, and the lead screw 402 is connected to a threaded hole on the crossbar 301.

[0042] A fixing sleeve 403 is provided on the side plate 401, and a worm gear 404 is provided in the fixing sleeve 403. A worm wheel is also provided on the lead screw 402 and connected to the worm gear 404.

[0043] The connection structure between the worm gear and the worm 404 is encapsulated in the fixing sleeve 403.

[0044] A turntable 405 is provided on the worm gear 404, and a handle 406 is provided on the turntable 405.

[0045] Simultaneously driving the two turntables 405 at both ends to move can cause the lead screw 402 to drive the tensioning carriage 300 to move, and drive the second roller 102 to move to achieve belt tensioning.

[0046] It should be noted that this application demonstrates a method of controlling the rotation of the turntable drive screw 402 by hand-cranking, thereby ultimately achieving belt tensioning. If the control force for tensioning exceeds the force that the turntable can control in conventional operation, it is necessary to sacrifice volume and weight and add electrical equipment such as a motor to control the rotation of the screw.

[0047] This application solves the problem that it is difficult to simultaneously install a tensioning device at the tail of the conveyor when setting up the drive, thus ensuring the reliable operation of both the head and tail drives and the normal operation of the tail tensioning function.

[0048] Specifically, it solves the problem that traditional head-driven, tail-tensioned reversible silo belt conveyors in multi-silo environments with limited height space cannot achieve long-distance, high-capacity operation due to limited tension. It also solves the problem that the built-in electric rollers used in previous head-and-tail dual-drive + tail-tensioned reversible silo belt conveyors resulted in insufficient design power and overheating shutdowns caused by prolonged overload operation.

[0049] The unique feature of this application is that it breaks away from the conventional thinking that the drive device must be fixed in a fixed position. Instead, the tail roller and the drive device are arranged on the tensioning trolley, which can move back and forth under the action of the tensioning device. This achieves bidirectional drive at both the head and tail, while ensuring that the belt has sufficient tension at all points to prevent slippage. This enables the configuration of a bidirectional reversible batching equipment with a long distance and large conveying capacity.

[0050] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
