Description
Technical Field
[0001] This utility model relates to the field of coal mining machinery technology, specifically to an adjustable belt conveyor intermediate frame. Background Technology
[0002] Due to the impact of mining operations, the roof and floor slabs and the rock masses on both sides of the roadway deform and shift into the roadway, causing the roadway floor to bulge upwards. When the bulge is large, it will make the floor of the transport roadway uneven, causing difficulties for the self-moving tail of the belt conveyor and the forward movement of the transfer machine, resulting in safety hazards.
[0003] Currently, the cleaning of the bottom slag in the transport roadway of a fully mechanized coal mining face is done manually using pneumatic picks and large chisels. This not only results in high labor intensity for employees and a high risk of personal injury in the complex working environment, but also low efficiency in manually repairing the roadway. The main reason is that the transport roadway is equipped with conveyor belts, self-propelled tail conveyors, transfer machines and other conveying equipment, which limits the working space and makes mechanized operations inconvenient.
[0004] Specifically, for the intermediate frame of the belt conveyor, the existing intermediate frame is in the form of a single channel steel. The distance between the intermediate frame and the ground is about 200mm-500mm, and a set of support legs is set every 3 meters or so. After the bottom of the belt conveyor bulges, there is no space for cleaning, which greatly affects the cleaning efficiency.
[0005] Given the current situation, people have been seeking an ideal technological solution to address the problem of limited cleaning space. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable belt conveyor intermediate frame that provides working space for cleaning the bottom drum of a belt conveyor in a coal mine roadway through an adjustable design.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is: an adjustable belt conveyor intermediate frame, including an arched frame and a traveling assembly; The arched frame is used to connect the intermediate frame and the self-propelled tail section, and a cleaning operation area is reserved below the arched frame; The walking components are located at the front and rear ends of the arched frame and are used for the self-movement of the arched frame.
[0008] This invention adds an arched frame to the traditional intermediate frame, uses the arched area of the arched frame to construct the bottom cleaning operation area, and uses a walking component to meet the walking requirements of the machine as it moves with the self-moving tail, thus solving the problem of limited space under the traditional intermediate frame making bottom cleaning impossible.
[0009] Preferably, the arched frame includes a front component, a middle component, and a rear component connected in sequence, with each component having at least one component. The front and rear components are both inclined components, and the middle component is a horizontal component, so that the assembled arched frame is arched.
[0010] Its advantage is that by using an inclined design, the overall structure is designed as an arch, which can meet the stability requirements of an arched structure.
[0011] Preferably, the front assembly includes a front frame, a front trough idler, and a front return idler. The front trough idler and the front return idler are installed in the front frame. The front return idler is located below the front trough idler. The transmission direction guided by the front trough idler and the transmission direction guided by the front return idler are both inclined.
[0012] Its advantage is that the roller structure on the front component meets the functional requirements of the support frame and can transfer materials.
[0013] Preferably, the central component includes a central frame, a central trough idler, and a central return idler. The central trough idler and the central return idler are installed in the central frame. The central return idler is located below the central trough idler. The transmission direction guided by the central trough idler and the transmission direction guided by the central return idler are both horizontally arranged.
[0014] The purpose of prioritizing the front components is to meet the functional requirements of material transfer.
[0015] Preferably, the rear assembly includes a rear frame, a rear trough idler, and a rear return idler. The rear trough idler and the rear return idler are installed in the rear frame. The rear return idler is located below the rear trough idler. The transmission direction guided by the rear trough idler and the transmission direction guided by the rear return idler are both inclined.
[0016] Together with the front and middle components, they form the basic conveying components for transferring materials.
[0017] Preferably, the walking assembly is installed on both sides of the front assembly and the rear assembly respectively. The walking assembly includes a translation mechanism and a lifting mechanism. The lifting mechanism is used to lift the arched frame so that the translation mechanism is off the ground. The translation mechanism is used to step forward and support the arched frame during the retraction of the lifting mechanism.
[0018] Its principle is similar to the step-like self-movement method of a support, using this self-movement structure to solve the problem of walking.
[0019] Preferably, the translation mechanism includes a translation slide, a translation cylinder, and a translation leg. The translation slide is a horizontal slide, and the translation leg is slidably installed in the translation slide. The translation cylinder is installed on the front frame or the rear frame to drive the translation leg to move back and forth along the translation slide.
[0020] The translation mechanism is designed to be driven by a translation cylinder, with the oil circuit coming from the hydraulic pressure of the entire hydraulic system, making it easier to obtain the power source.
[0021] Preferably, the lifting mechanism includes a lifting cylinder, a lifting slide, a guide sleeve, and a bottom support shoe. The bottom support shoe is connected to the bottom end of the guide sleeve. The guide sleeve slides in cooperation with the lifting slide. The lifting slide is vertically oriented as a whole. The lifting cylinder is mounted on the front frame or the rear frame to drive the guide sleeve to move vertically up and down along the lifting slide.
[0022] The lifting mechanism and the translation mechanism work together to achieve a step-like self-moving function.
[0023] Preferably, the cylinder body of the translation cylinder is hinged to the front frame or the rear frame, and the piston rod of the translation cylinder is hinged to the translation support leg.
[0024] Preferably, the cylinder body of the lifting cylinder is hinged to the front frame or the rear frame, the piston rod of the lifting cylinder is hinged to the guide sleeve, and the guide sleeve is hinged to the bottom support shoe.
[0025] Hinged connections can prevent various movements from getting stuck.
[0026] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages: The belt conveyor intermediate frame designed in this utility model is used to be installed between the intermediate frame and the self-moving tail of the roadway belt conveyor. The front component is adjacent to the intermediate frame, and the rear component is adjacent to the self-moving tail. When the amount of floor heave in the roadway is large, the floor of the transport roadway will be uneven. This intermediate frame provides an effective working space for cleaning the floor heave. At the same time, the self-moving components set at both ends can support the overall self-movement of the intermediate frame without the need for other mechanisms. In conjunction with the movement of the self-moving tail, it effectively solves the problem of limited floor heave cleaning space in traditional belt conveyor intermediate frames.

Detailed Implementation
[0033] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0034] like Figures 1-5 As shown, an adjustable belt conveyor intermediate frame includes an arched frame 1 and a traveling assembly 2.
[0035] The arched frame 1 is used to connect the intermediate frame 3 and the self-moving tail 4. The front end is adjacent to the intermediate frame 3 and the rear end is adjacent to the self-moving tail 4. A cleaning operation area 5 is reserved below the arched frame 1.
[0036] The walking component 2 is located at the front and rear ends of the arched frame 1 and is used for the self-movement of the arched frame 1. The adjustable belt conveyor intermediate frame serves as an intermediate section of the entire belt conveyor without affecting the overall drive.
[0037] Specifically, the arched frame 1 includes a front component 100, a middle component 200, and a rear component 300 connected in sequence. Each component has at least one unit. The front component 100 and the rear component 300 are both components with an inclination angle, and the middle component 200 is a horizontal component, so that the assembled arched frame 1 is arched.
[0038] In this embodiment, the front assembly 100 includes a front frame 101, a front trough idler 102, and a front return idler 103. The front trough idler 102 and the front return idler 103 are installed in the front frame 101. The front return idler 103 is located below the front trough idler 102. The transmission direction guided by the front trough idler 102 and the transmission direction guided by the front return idler 103 are both inclined. The rear assembly includes a rear frame, a rear trough idler, and a rear return idler. Its structure is basically the same as that of the front assembly 100, except for the difference in length and inclination angle, so it will not be described in detail.
[0039] The central component 200 includes a central frame 201, a central trough idler 202, and a central return idler 203. The central trough idler 202 and the central return idler 203 are installed in the central frame 201. The central return idler 203 is located below the central trough idler 202. The transmission direction guided by the central trough idler 202 and the transmission direction guided by the central return idler 203 are both horizontally arranged.
[0040] In this embodiment, the walking component 2 is installed on both sides of the front component 100 and the rear component 300 respectively. The walking component 2 includes a translation mechanism 104 and a lifting mechanism 105. The lifting mechanism is used to lift the arched frame so that the translation mechanism is off the ground. The translation mechanism is used to step forward and support the arched frame during the retraction of the lifting mechanism.
[0041] Specifically, the translation mechanism includes a translation slide 401, a translation cylinder 402, and a translation leg 403. The translation slide 401 is a horizontal slide, and the translation leg 403 is slidably installed in the translation slide 401. The translation cylinder 402 is installed on the front frame 100 or the rear frame 300 to drive the translation leg 403 to move back and forth along the translation slide 401. The cylinder body of the translation cylinder 402 is hinged to the front frame 100 or the rear frame 300, and the piston rod of the translation cylinder 402 is hinged to the translation leg 403.
[0042] The lifting mechanism includes a lifting cylinder 404, a lifting slide 405, a guide sleeve 406, and a bottom support shoe 407. The bottom support shoe 407 is connected to the bottom end of the guide sleeve 406. The guide sleeve 406 is slidably engaged with the lifting slide 405. The lifting slide 405 is vertically oriented. The lifting cylinder 404 is mounted on the front frame 100 or the rear frame 300 to drive the guide sleeve 406 to move vertically up and down along the lifting slide 405. The cylinder body of the lifting cylinder 404 is hinged to the front frame 100 or the rear frame 300. The piston rod of the lifting cylinder 404 is hinged to the guide sleeve 406. The guide sleeve 406 is hinged to the bottom support shoe 407.
[0043] Technical principle explanation: Due to the inclined design of the front frame 100 and the rear frame 300, the entire frame has an arched structure, which naturally creates a sufficient space for bottom cleaning operations under the arched frame for bottom drum cleaning operations.
[0044] As the work surface moves forward, the last section of the intermediate frame is removed. At this time, the adjustable belt conveyor intermediate frame moves forward by means of the translation component 2.
[0045] The moving process is as follows: The lifting cylinder 404 in the front assembly 100 and the rear assembly 300 extends, pushing the guide sleeve 406 and the bottom support shoe 407. After the bottom support shoe 407 supports the ground, the entire intermediate frame of the adjustable belt conveyor is lifted. After being lifted into position, the translation cylinder 402 is adjusted to move the translation leg 403 to the front. The lifting cylinder 404 is retracted so that the translation leg 403 supports the ground. After the lifting cylinder 404 is retracted into position, the translation cylinder 402 extends. The cylinder body of the translation cylinder 402 is hinged to the front frame 101, and the piston rod of the translation cylinder 402 is hinged to the translation leg 403. Therefore, after the translation cylinder 402 extends, it drives the entire intermediate frame of the adjustable belt conveyor to move forward. After the translation cylinder 402 extends into position, the moving steps are repeated to move the entire intermediate frame forward. After the movement, the tail of the self-moving machine moves forward accordingly.
[0046] The two lifting cylinders on the left and right sides of the lifting device can be controlled independently. When the intermediate frame tilts as a whole due to unevenness of the base plate after it has been moved into place, the posture of the intermediate frame can be adjusted by adjusting the lifting cylinders.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
