Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and specifically to a self-moving frame for belt conveyors. Background Technology

[0002] Currently, in order to adapt to various underground working conditions in coal mines, a transition frame is usually set between the tail of the belt conveyor and the belt conveyor. The traditional transition frame is usually an integral structure and is generally complex. After the tunneling machine in the mine roadway has been working for a period of time, it needs to move forward, and the transition frame also needs to move forward with the tunneling machine. However, the movement of the transition frame is difficult and slow, and it is prone to problems such as belt deviation, which seriously restricts production efficiency and economic benefits. Utility Model Content

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a self-moving conveyor frame for use as a transition between the tail end of a conveyor belt and a belt conveyor. This self-moving conveyor frame can move independently, has a simple structure, is easy to operate, and improves production efficiency and economic benefits.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A self-moving frame for a belt conveyor includes a first support, a second support, and a support device. The first support is provided with a vertical reciprocating linear motion drive mechanism, and the support device is located below the first support and is disposed on the vertical reciprocating linear motion drive mechanism. The second support is laterally slidably disposed on the first support, and a lateral reciprocating linear motion drive mechanism is disposed between the second support and the first support.

[0006] The first support includes two first side frames and two first support rods. Each first side frame includes a first connecting rod, a first slide rail, and two first columns. The two first columns are spaced apart and vertically arranged. The first connecting rod and the first slide rail are spaced apart and horizontally connected between the two first columns. The two first support rods are correspondingly connected between the first columns of the two first side frames.

[0007] The vertical reciprocating linear motion drive mechanism includes four vertical reciprocating linear motion drive components, which are respectively disposed in the corresponding first column.

[0008] The second bracket includes two second side frames and two second support rods. Each second side frame includes a second connecting rod, a second slide rail, and two second columns. The two second columns are spaced apart and vertically arranged. The second connecting rod and the second slide rail are spaced apart and horizontally connected between the two second columns. The two second support rods are correspondingly connected between the second columns of the two second side frames. The two second slide rails are slidably connected to the corresponding first slide rails.

[0009] The transverse reciprocating linear motion drive mechanism includes two transverse reciprocating linear motion drive components, which are respectively connected between the first column of the first side frame and the second column of the second side frame.

[0010] The support device includes two support mechanisms, which are respectively disposed at both ends of the first support along its length. Each support mechanism includes a support base and a longitudinal reciprocating linear motion drive. Two sliders are slidably disposed on the support base. The longitudinal reciprocating linear motion drive is disposed on the support base and has two power output parts with opposite directions of motion. The two power output parts are respectively connected to the corresponding sliders. The four vertical reciprocating linear motion drive parts are respectively hinged to the corresponding sliders.

[0011] Among them, upper roller assemblies and lower rollers are provided between the two first columns corresponding to the two first side frames and between the two second columns corresponding to the two second side frames.

[0012] The upper idler assembly includes an idler frame and an upper idler and an anti-deviation vertical roller disposed on the idler frame. The idler frame is adjustablely disposed between the two first columns or the two second columns.

[0013] The lower roller is adjustablely positioned between the two first columns or the two second columns.

[0014] The first support is provided with a pressure roller assembly, which includes a roller frame and a pressure roller. The roller frame is fixedly mounted on the first support, and the pressure roller is adjustablely mounted on the roller frame and located above the upper idler roller assembly.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are:

[0016] The self-moving conveyor frame provided by this utility model is equipped with a horizontal reciprocating linear motion drive mechanism and a vertical reciprocating linear motion drive mechanism. The horizontal reciprocating linear motion drive mechanism drives the first or second support to move horizontally, while the vertical reciprocating linear motion drive mechanism drives the support device to contact or detach from the ground. The two mechanisms work together to achieve self-moving of the conveyor frame without external force. Therefore, compared with the prior art, the self-moving conveyor frame of this utility model can move on its own, has a simple structure, is easy to operate, and improves production efficiency and economic benefits.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] like Figures 1 to 3As shown, this embodiment discloses a self-moving frame for a belt conveyor, including a first support 1, a second support 2, and a support device 3. The first support 1 is provided with a vertical reciprocating linear motion drive mechanism 4, and the support device 3 is located below the first support 1 and is provided on the vertical reciprocating linear motion drive mechanism 4. The second support 2 is laterally slidably disposed on the first support 1, and a lateral reciprocating linear motion drive mechanism 5 is provided between the second support 2 and the first support 1.

[0023] In this embodiment, the self-moving conveyor frame is driven by a transverse reciprocating linear motion drive mechanism 5 to move the first support 1 or the second support 2 laterally, and by a vertical reciprocating linear motion drive mechanism 4 to drive the support device 3 to contact or detach from the ground. The two work together to achieve self-moving of the conveyor frame without external force. Its structure is simple and easy to operate, improving production efficiency and economic benefits. At the same time, the self-moving conveyor frame adopts the above-mentioned split structure, which can be flexibly disassembled and is easy to install in the well, further improving work efficiency.

[0024] In this embodiment, the first support 1 includes two first side frames and two first support rods 14. Each first side frame includes a first connecting rod 11, a first slide rail 12, and two first columns 13. The two first columns 13 are spaced apart and vertically arranged. The first connecting rod 11 and the first slide rail 12 are spaced apart and horizontally connected between the two first columns 13. The two first support rods 14 are correspondingly connected between the first columns 13 of the two first side frames. This arrangement achieves a fixed connection of the first support 1.

[0025] The vertical reciprocating linear motion drive mechanism 4 in this embodiment includes four vertical reciprocating linear motion drive components 41, which are respectively disposed in the corresponding first columns 13. Since hydraulic cylinders have high transmission efficiency, fast response speed, and are easy to maintain, the vertical reciprocating linear motion drive components 41 in this embodiment are preferably hydraulic cylinders. In practical applications, the vertical reciprocating linear motion drive components 41 can also be pneumatic cylinders, electric cylinders, or linear motors, depending on actual needs. This embodiment does not impose any restrictions on this.

[0026] In this embodiment, the second support 2 includes two second side frames and two second support rods 24. Each second side frame includes a second connecting rod 21, a second slide rail 22, and two second columns 23. The two second columns 23 are spaced apart and vertically arranged. The second connecting rod 21 and the second slide rail 22 are spaced apart and horizontally connected between the two second columns 23. The two second support rods 24 are correspondingly connected between the second columns 23 of the two second side frames. The two second slide rails 22 are slidably connected to corresponding first slide rails 12. Specifically, the inner side of the first slide rail 12 has a groove, and the second slide rail 22 is slidably disposed within the corresponding groove. This arrangement achieves a fixed connection for the second support 2 and a sliding connection between the first support 1 and the second support 2.

[0027] The transverse reciprocating linear motion drive mechanism 5 in this embodiment includes two transverse reciprocating linear motion drive components 51, which are correspondingly connected between the first column 13 of the first side frame and the second column 23 of the second side frame. Specifically, the transverse reciprocating linear motion drive component 51 in this embodiment is preferably a hydraulic cylinder. In practical applications, the transverse reciprocating linear motion drive component 51 can also be a pneumatic cylinder, an electric cylinder, or a linear motor, depending on the actual needs. This embodiment does not impose any restrictions on this.

[0028] The support device 3 in this embodiment includes two support mechanisms, which are respectively arranged at both ends of the first bracket 1 along its length.

[0029] Specifically, the support mechanism includes a support base 31 and a longitudinal reciprocating linear motion drive 32. Two sliders 33 are slidably mounted on the support base 31. The longitudinal reciprocating linear motion drive 32 is mounted on the support base 31 and has two power outputs with opposite directions of motion. The two power outputs are respectively connected to corresponding sliders 33. Four vertical reciprocating linear motion drive components 41 are respectively hinged to corresponding sliders 33. Through the cooperation of the longitudinal reciprocating linear motion drive components 32 of the two support mechanisms, the angle between the entire self-moving frame of the belt conveyor and the horizontal plane can be adjusted, realizing the angle fine-tuning function of the self-moving frame of the belt conveyor and effectively preventing belt misalignment.

[0030] In this embodiment, the longitudinal reciprocating linear motion drive 32 is preferably a hydraulic cylinder. In practical applications, the longitudinal reciprocating linear motion drive 32 can also be a pneumatic cylinder, an electric cylinder, or a linear motor. The specific choice depends on the actual needs, and this embodiment does not impose any restrictions on this.

[0031] In this embodiment, upper roller assemblies 6 and lower rollers 7 are respectively provided between the two first columns 13 corresponding to the two first side frames and between the two second columns 23 corresponding to the two second side frames. This arrangement facilitates the installation of the conveyor belt.

[0032] In this embodiment, the upper idler assembly 6 includes an idler frame 61 and an upper idler 62 and an anti-deviation vertical roller 63 mounted on the idler frame 61. The idler frame 61 is adjustablely positioned between two first columns 13 or two second columns 23; the lower idler 7 is also adjustablely positioned between two first columns 13 or two second columns 23. This configuration meets the usage requirements of various working conditions in underground coal mines.

[0033] Specifically, the first column 13 or the second column 23 is provided with multiple column connection holes 130, and the roller frame 61 is provided with multiple roller frame connection holes 610. The position adjustment of the roller frame 61 can be achieved by the bolt assembly cooperating with different column connection holes 130 and roller frame connection holes 610. The first column 13 or the second column 23 is provided with multiple vertically arranged elongated slots 131. The position adjustment of the lower roller 7 can be achieved by the lower roller 7 cooperating with different slots 131.

[0034] In this embodiment, a belt pressure roller assembly 8 is provided on the first support 1. The belt pressure roller assembly 8 includes a roller frame 81 and a belt pressure roller 82. The roller frame 81 is fixedly mounted on the first slide rail 12 of the first support 1, and the belt pressure roller 82 is adjustablely mounted on the roller frame 81 and located above the upper idler roller assembly 6. By setting the belt pressure roller assembly 8, belt pressure, changing the running direction of the conveyor belt, and applying force are realized, which can ensure the normal operation and efficiency of the belt conveyor, while preventing the conveyor belt from floating above the upper idler roller 62 due to tension.

[0035] In this embodiment, the wheel frame 81 is provided with two bearing seats 810. Both bearing seats 810 are adjustable in position on the wheel frame 81 via an elongated hole adjustment structure (existing technology). The pressure roller 82 is disposed on the two bearing seats 810, thereby realizing the position adjustment of the pressure roller 82. Of course, other position adjustment structures in the prior art can also be used, and the specific selection depends on actual needs. This embodiment does not limit this.

[0036] In this embodiment, when the self-moving frame of the belt conveyor moves, the vertical reciprocating linear motion drive mechanism 4 drives the support device 3 to detach from the ground, and the horizontal reciprocating linear motion drive mechanism 5 drives the first bracket 1 to move a preset distance relative to the second bracket 2. Then, the vertical reciprocating linear motion drive mechanism 4 drives the support device 3 to support the ground and lifts the second bracket 2 so that the second bracket 2 detaches from the ground. Then, the horizontal reciprocating linear motion drive mechanism 5 drives the second bracket 2 to move a preset distance relative to the first bracket 1, thereby realizing the self-moving of the self-moving frame of the belt conveyor.

[0037] When the conveyor belt is tilted at a horizontal angle, the angle between the self-moving frame of the conveyor belt and the horizontal plane can be finely adjusted by two longitudinal reciprocating linear motion drive components 32 to straighten the belt. During adjustment, the power output part on one side of one longitudinal reciprocating linear motion drive component 32 extends, and the power output part on the other side of the other longitudinal reciprocating linear motion drive component 32 extends, thereby realizing the fine adjustment of the self-moving frame of the conveyor belt.

[0038] The above describes in detail a preferred embodiment of the self-moving conveyor frame of this utility model. Many other embodiments are also described but will not be elaborated upon here. In summary, the self-moving conveyor frame of this utility model achieves self-movement, has a simple structure, is easy to operate, and improves production efficiency and economic benefits.

[0039] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
