Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to a bidirectional telescopic belt conveyor frame and belt conveyor. Background Technology

[0002] In the steel network of modern mine production, telescopic belt conveyors act as the joints of the conveyor system, their flexibility directly determining the vitality of the production line. However, current equipment under the existing technological framework faces multiple structural contradictions: when tunneling operations demand a longer conveying radius, the equipment can only barely cope with fragmented mechanical responses; when the retreat process requires precise retraction, the problem of unidirectional operation is exposed. This fundamental contradiction between two-way demand and unidirectional capability forces the production process to constantly consume valuable time costs in downtime and reorganization. During construction, workers have to frequently intervene in basic operations such as tension adjustment and track correction. This reliance on manual labor not only increases the workload but also affects production efficiency. Faced with increasingly complex underground working conditions, traditional rigid structures show obvious adaptability deficiencies. Current equipment often needs to sacrifice stability or durability to maintain basic functions in the face of dynamic demands such as angle changes and load fluctuations. Therefore, existing telescopic belt conveyors mainly suffer from short telescopic distances and unidirectional telescopic directions, failing to meet the telescopic distance requirements of both tunneling and retreat conditions simultaneously. Furthermore, some telescopic belt conveyors require manual assistance, increasing the labor intensity of workers and affecting production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a bidirectional telescopic belt conveyor frame and belt conveyor to solve the technical problem that existing telescopic belt devices cannot simultaneously meet the telescopic distance requirements under both tunneling and retraction conditions. The specific technical solution is as follows: This utility model provides a bidirectional telescopic belt conveyor frame, which is set between the self-moving tail of the belt conveyor and the tunneling and anchoring equipment. The bidirectional telescopic belt conveyor frame includes a support device, multiple standard sections, and multiple first linear drive components. The first linear drive components are connected between every two adjacent standard sections. The support device is connected to the rear end of the last standard section. The foremost standard section is used to connect to the traction equipment. Each standard section includes a guide rail frame, a sliding frame, multiple idler frames, and multiple scissor-type telescopic components. The sliding frame is slidably installed on the guide rail frame. The multiple idler frames are installed at intervals on the sliding frame. The scissor-type telescopic components are connected between every two adjacent idler frames.

[0004] A further improvement of this utility model of bidirectional telescopic belt conveyor frame is that a second linear drive component is connected between the guide rail frame and the sliding frame.

[0005] A further improvement of this utility model of bidirectional telescopic belt conveyor frame is that the standard section contains two sliding frames, which are slidably installed at both ends of the guide rail frame.

[0006] A further improvement of this utility model of a bidirectional telescopic belt conveyor frame is that both the first linear drive component and the second linear drive component are hydraulic cylinders.

[0007] A further improvement of this utility model of bidirectional telescopic belt conveyor frame is that the guide rail frame is provided with a longitudinal sleeve, the sliding frame is provided with a longitudinal insert rod, the longitudinal insert rod is slidably inserted into the longitudinal sleeve, and the idler roller frame is fixed on the longitudinal insert rod.

[0008] A further improvement of this utility model of a bidirectional telescopic belt conveyor frame is that the scissor-type telescopic component is formed by hinged multiple scissor struts.

[0009] A further improvement of this utility model of bidirectional telescopic belt conveyor frame is that a central segmentation mechanism is fixed on the guide rail frame, and two adjacent scissor-type telescopic components are connected to the central segmentation mechanism.

[0010] This utility model also provides a belt conveyor, including the bidirectional telescopic belt conveyor frame as described above.

[0011] The application of the technical solution of this utility model has the following beneficial effects: This utility model relates to a bidirectional telescopic belt conveyor frame. By being positioned between the self-moving tail of the belt conveyor and the tunneling and anchoring equipment, it allows the belt conveyor to extend and retract bidirectionally during both tunneling and retraction operations under the action of the traction equipment. This solves the technical problem that existing telescopic belt devices cannot simultaneously meet the extension distance requirements for both tunneling and retraction conditions. This utility model can increase the overall telescopic length of the bidirectional telescopic belt conveyor frame by increasing the number of standard sections, effectively solving the problems of insufficient extension distance and the need for manual intervention in existing equipment.

[0015] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] See Figures 1-5 As shown, a bidirectional telescopic belt conveyor frame is installed between the self-moving tail of the belt conveyor and the tunneling and anchoring equipment. The bidirectional telescopic belt conveyor frame includes a support device 1, multiple standard sections 2, and multiple first linear drive components 3. The first linear drive components 3 are connected between each two adjacent standard sections 2. The support device 1 is connected to the rear end of the last standard section 2. The foremost standard section 2 is used to connect to the traction equipment. Each standard section 2 includes a guide rail frame 201, a sliding frame 205, multiple idler frames 204, and multiple scissor-type telescopic components 203. The sliding frame 205 is slidably installed on the guide rail frame 201. The multiple idler frames 204 are installed at intervals on the sliding frame 205. The scissor-type telescopic components 203 are connected between each two adjacent idler frames 204.

[0017] This invention adds a telescopic belt conveyor frame between the conventional self-moving tail section of a belt conveyor and the tunneling and anchoring equipment. The number of standard sections 2 can be configured according to the actual telescopic distance requirements. During the telescopic movement of the belt conveyor, the extension or retraction of the belt laid on the bidirectional telescopic belt conveyor frame of this invention is controlled by an external belt storage bin. Adjacent standard sections 2 are connected by a first linear drive component 3, which can provide mutual force. A supporting device 1 is arranged at the rear end of the bidirectional telescopic belt conveyor frame, which can be fixed to the ground to provide supporting force. The front end can be provided with traction force by equipment such as a winch.

[0018] Preferred, such as Figure 3 As shown, a second linear drive 4 is connected between the guide rail 201 and the sliding frame 205. Specifically, the second linear drive 4 is connected between the crossbar of the guide rail 201 and the crossbar of the sliding frame 205, thereby adjusting the length of the entire standard section 2.

[0019] Preferably, the standard section 2 contains two sliding frames 205, which are slidably mounted on both ends of the guide rail frame 201. Two second linear drive members 4 are installed in the standard section 2, with opposite driving directions, thereby driving the sliding frames 205 to extend or retract relative to the guide rail frame 201 at both ends, achieving a bidirectional telescopic effect. In this embodiment, the two second linear drive members 4, with a telescopic stroke of 3500mm, drive the sliding frames 205 to slide within the guide rail frame 201, thus achieving independent telescopic movement of the conveyor belt frame to both sides.

[0020] Preferably, both the first linear drive 3 and the second linear drive 4 are hydraulic cylinders, thereby enabling automatic extension and retraction. Alternatively, the first linear drive 3 and the second linear drive 4 can be replaced with pneumatic cylinders or other direct drive mechanisms as needed.

[0021] Preferably, the guide rail frame 201 is provided with a longitudinal sleeve, and the sliding frame 205 is provided with a longitudinal insert rod. The longitudinal insert rod is slidably inserted into the longitudinal sleeve, and the roller frame 204 is fixed to the longitudinal insert rod. Specifically, the longitudinal sleeve and the crossbar of the guide rail frame 201 are fixed perpendicularly to each other to form the guide rail frame 201, and the crossbar of the sliding frame 205 and the roller frame 204 are both fixed at the end position of the longitudinal insert rod. In this embodiment, the structure of the longitudinal sleeve and the longitudinal insert rod adopts a mother-and-child rod structure, and the sliding structure of the guide rail frame 201 and the sliding frame 205 can also be replaced by a guide rail or slide rail structure.

[0022] Preferred, such as Figure 1 and Figure 2 As shown, the scissor-type telescopic component 203 is composed of multiple scissor struts hinged together. These struts form a telescopic structure, thus providing support for the belt and ensuring the stability of the entire bidirectional telescopic belt conveyor frame. In this embodiment, the maximum extension length of the scissor-type telescopic component 203 can reach 6-7 meters. The scissor-type telescopic component 203 adopts a center-segmented design, which can assist in the asynchronous operation of the hydraulic cylinder. Taking a conventional three-section telescopic frame as an example, the overall length of the belt conveyor in its retracted state is approximately 15 meters, and in its extended state, it can reach 35 meters, with an effective telescopic distance of over 20 meters, which can meet the needs of most working conditions. Furthermore, adjustment devices can be arranged on both sides of the telescopic frame, and lateral adjustment can be achieved using laterally arranged linear drive components.

[0023] Preferably, a central segmentation mechanism 202 is fixed on the guide rail frame 201, and two adjacent scissor-type telescopic members 203 are connected to the central segmentation mechanism 202. Both the roller frame 204 and the central segmentation mechanism 202 are vertical frames. The central segmentation mechanism 202 has two sets of hinge points, which can be used to install two adjacent scissor-type telescopic members 203, thereby connecting the scissor-type telescopic members 203 on both sides.

[0024] This utility model also provides a belt conveyor, including the bidirectional telescopic belt conveyor frame as described above.

[0025] During the tunneling process, standard section 2 extends forward through traction and the force of the connecting second linear drive component 4, such as... Figure 5 As shown; during the retraction process, the machine retracts backward through the force exerted by the connecting first linear drive 3 and second linear drive 4, as... Figure 4 As shown. In both working states, the support device 1 is in the support working state. During the self-moving tail of the belt conveyor, the support device 1 cancels the support, and the telescopic frame retracts forward.

[0026] This utility model relates to a bidirectional telescopic belt conveyor frame. By being positioned between the self-moving tail of the belt conveyor and the tunneling and anchoring equipment, it allows the belt conveyor to extend and retract bidirectionally during both tunneling and retraction operations under the action of the traction equipment. This solves the technical problem that existing telescopic belt devices cannot simultaneously meet the extension distance requirements for both tunneling and retraction conditions. This utility model can increase the overall telescopic length of the bidirectional telescopic belt conveyor frame by increasing the number of standard sections 2, effectively solving the problems of insufficient extension distance and the need for manual intervention in existing equipment. This improves the mechanization level of coal mine production, facilitates equipment maintenance, reduces worker labor intensity, and increases production efficiency.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
