Description

Technical Field

[0001] This application belongs to the field of rapid tunneling technology in mines, specifically relating to an assembly tooling for belt conveyors. Background Technology

[0002] Currently, belt conveyor extension at the tunneling face must be carried out during belt conveyor shutdown for maintenance. Before extension, the belt is disconnected at the hoisting point. One end of the hoisted full roll of belt is connected to the disconnected end using a belt buckle. Workers then operate equipment such as the tunneling face feeder and crusher to drag the tail of the conveyor forward a certain distance before stopping. Belt frame assembly workers then assemble the belt frame behind the tail of the conveyor, alternating back and forth to complete the belt extension. Once the tail of the conveyor is in position and the belt frame assembly is complete, the belt is connected and tensioned, completing the belt extension.

[0003] In recent years, equipment such as self-moving tail sections of tunneling machines have been increasingly used. Although the application of long-distance telescopic belt conveyors has achieved the goal of the tail section moving forward continuously during the tunneling process, it is still necessary to use downtime for maintenance to retract the already extended telescopic frame and assemble the belt conveyor behind the telescopic frame to complete the extension of the belt conveyor and prepare for subsequent production.

[0004] In related technologies, the stop-and-extend belt conveyor mode for tunneling faces cannot achieve continuous coal transportation during production. In the self-moving tail mode for tunneling, the belt telescopic frame system is large, inconvenient to operate, and requires the stop-and-extend belt conveyor, resulting in low tunneling efficiency.

[0006] Therefore, this application provides an assembly fixture for a belt conveyor, comprising: a frame including a bottom beam; a first channel body and a second channel body, spaced apart from each other in the frame, with the first channel body located above the second channel body, the first channel body being used to accommodate at least the upper belt segment of the conveyor belt machine, and the second channel body being used to accommodate at least the lower belt segment of the conveyor belt machine; a guide plate connected to the bottom beam, the guide plate and the bottom beam defining a sliding groove, the sliding groove being slidably connected to the belt conveyor for limiting and guiding the belt conveyor.

[0007] In one possible implementation, a protrusion is provided in the middle of the guide plate, and the protrusion extends along the length direction of the frame; the protrusion, the guide plate, and the bottom beam together define the groove.

[0008] In one possible implementation, the assembly fixture further includes: a first idler roller and a second idler roller, the first idler roller being rotatably disposed at the inlet end of the first channel body, and the second idler roller being rotatably disposed at the outlet end of the first channel body, the first idler roller and the second idler roller being used to guide the upper belt segment to move from the inlet end to the outlet end; a third idler roller being rotatably disposed on the outlet side of the second channel body, and being used to guide the lower belt segment to run; the outlet side of the second channel body is located below the inlet end of the first channel body.

[0009] In one possible implementation, the assembly fixture further includes: a first anti-deviation idler roller, rotatably mounted on the frame, the first anti-deviation idler roller being located on the side of the first idler roller assembly away from the inlet end of the first channel body, and a plurality of the first anti-deviation idler rollers being spaced apart for limiting the upper belt segment.

[0010] In one possible implementation, the assembly fixture further includes: a second anti-deviation idler roller, rotatably mounted on the frame, the second anti-deviation idler roller being located between the third idler roller and the outlet side of the second channel body, and a plurality of second anti-deviation idler rollers being spaced apart for limiting the lower belt segment.

[0011] In one possible implementation, the first channel body is formed by a first base plate, first side plates respectively connected to both sides of the first base plate, and a first cover plate covering the top of the first side plates, wherein the first side plates are connected to the frame.

[0012] In one possible implementation, the second channel body is formed by a second base plate, second side plates respectively connected to both sides of the second base plate, and a second cover plate covering the top of the second side plates, wherein the second base plate and the second side plates are respectively connected to the frame.

[0013] In one possible implementation, the second channel body is spaced apart from the bottom beam so that the inlet side of the second channel body is suspended; and the inlet side of the second channel body is located below the outlet end of the first channel body.

[0014] In one possible implementation, the assembly fixture further includes a connecting lug, disposed on the bottom beam and located on one side of the assembly fixture in the forward direction, for connection with the traction device.

[0015] In one possible implementation, the assembly fixture further includes a pedestrian bridge spanning the frame and located on one side of the assembly fixture in the direction of travel, for the passage of operators.

[0016] The assembly fixture for belt conveyors provided in this application can achieve at least the following technical effects: In this application, the assembly fixture for the belt conveyor includes a frame, which includes a bottom beam. The bottom beam serves as the load-bearing foundation of the frame, providing installation support for the chute, the first channel body, the second channel body, and the connecting lugs, and stably transmitting traction force to the entire fixture. The first channel body and the second channel body are spaced apart within the frame, with the first channel body positioned above the second channel body. The first channel body is used to accommodate at least the upper belt segment of the conveyor belt, and the second channel body is used to accommodate at least the lower belt segment of the conveyor belt. By independently arranging the upper and lower belt segments, the upper and lower belt segments can each travel independently within the assembly fixture without interfering with each other, which is beneficial for the continuous and stable operation of the belt during the movement of the assembly fixture. A guide plate is connected to the bottom beam, and the guide plate and the bottom beam define a chute. The chute is slidably connected to the belt conveyor, used for limiting and guiding the belt conveyor. By limiting and guiding the belt conveyor through the chute, the belt conveyor can slide out relative to the assembly fixture in a predetermined direction and automatically land when the assembly fixture moves, achieving stable support for the belt. This application utilizes a first channel and a second channel to independently accommodate and isolate the upper and lower belt sections, respectively, enabling the belt to operate continuously during the movement of the assembly fixture without requiring machine downtime. A guide plate and bottom beam define a chute, allowing the belt frame to slide relative to the assembly fixture and automatically land on the ground during movement, providing stable support for the belt. This enables continuous assembly and extension of the belt frame during belt operation, effectively improving tunneling efficiency.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0026] Combination Figures 1 to 5 As shown, this application provides an assembly fixture 100 for a belt conveyor 200, including a frame 101, a first channel body 103, a second channel body 104, and a guide plate 105. The frame 101 includes a bottom beam 102. The first channel body 103 and the second channel body 104 are spaced apart from each other on the frame 101, with the first channel body 103 positioned above the second channel body 104. The first channel body 103 is used to accommodate at least the upper belt section of the conveyor belt machine, and the second channel body 104 is used to accommodate at least the lower belt section of the conveyor belt machine. The guide plate 105 is connected to the bottom beam 102, and the guide plate 105 and the bottom beam 102 define a groove 106. The groove 106 is slidably connected to the belt conveyor 200 for limiting and guiding the belt conveyor 200.

[0027] It should be noted that the belt of the conveyor belt machine has a ring structure, which includes an upper belt section and a lower belt section distributed along the ring running path. The upper belt section is the load-bearing part located above the conveyor belt machine, used to transport materials, while the lower belt section is the return part located below the conveyor belt machine, used to complete the belt's circulation and rewinding.

[0028] The upper belt section runs within the first channel body 103, and the lower belt section runs within the second channel body 104, ensuring continuous operation of the belts throughout the entire process of the assembly fixture 100 being pulled forward, without requiring machine shutdown. The first channel body 103 and the second channel body 104 physically isolate and spatially constrain the upper and lower belt sections, respectively, preventing the belts from deviating from the preset path or interfering with each other during the movement of the assembly fixture 100, thus maintaining stable operation. The guide plate 105 and the groove 106 defined by the bottom beam 102 limit the width of the assembled belt frame 200 and guide it in the length direction, maintaining stable guidance during the movement of the assembly fixture 100. The width direction is... Figure 1 The left and right directions, and the length direction are Figure 1 Forward and backward directions Specifically, when the traction equipment pulls the assembly fixture 100 to move, the newly assembled belt frame 200 is connected to the previous belt frame 200 that has already been placed on the ground without moving with the assembly fixture 100. Under the limiting and guiding action of the slide 106, it slides out relative to the assembly fixture 100 along the slide 106. After sliding out, the belt frame 200 automatically lands on the ground and immediately provides stable support for the running belt.

[0029] Combination Figure 1 and Figure 2 As shown, in some embodiments, a protrusion 107 is provided in the middle of the guide plate 105, and the protrusion 107 extends along the length direction of the frame 101. The protrusion 107, the guide plate 105, and the bottom beam 101 together define the groove 106.

[0030] The protrusion 107, guide plate 105, and bottom beam 101 together define the slide groove 106. The slide groove 106 limits the support 201 of the belt conveyor 200, ensuring that the support 201 does not deviate when the assembly fixture 100 moves, and can only slide along the length of the frame 101, i.e., along the length of the slide groove 106. The support 201 may include upright legs. The guide plate 105 and the protrusion 107 are integrally convex structures, so that the protrusion 107, guide plate 105, and bottom beam 102 together define the slide groove 106. The slide groove 106 limits the width of the support 201 of the belt conveyor 200 and guides it in the length direction, allowing the belt conveyor 200 to automatically slide out along the slide groove 106 and land when the assembly fixture 100 moves forward. This achieves automatic extension and support conversion of the belt conveyor 200 without manual intervention, improving work efficiency and safety.

[0031] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the assembly fixture 100 further includes a first idler roller 109, a second idler roller 110, and a third idler roller 111. The first idler roller 109 is rotatably disposed at the inlet end of the first channel body 103, and the second idler roller 110 is rotatably disposed at the outlet end of the first channel body 103. The first idler roller 109 and the second idler roller 110 are used to guide the upper belt segment to move from the inlet end to the outlet end. The third idler roller 111 is rotatably disposed on the outlet side of the second channel body 104 and is used to guide the lower belt segment to run. The outlet side of the second channel body 104 is located below the inlet end of the first channel body 103.

[0032] The first channel body 103 has one idler roller at its inlet and one at its outlet, namely, the first idler roller 109 and the second idler roller 110. The second channel body 104 has one idler roller at its outlet, namely, the third idler roller 111. The three idlers provide support and steering guidance at the key nodes of the belt's entry and exit, respectively, converting sliding friction into rolling friction, reducing running resistance and equipment wear, and ensuring smooth belt operation when entering and exiting the trough. By setting the outlet side of the second channel body 104 below the inlet end of the first channel body 103, the lower belt segment enters the bottom belt flat idler roller 204 of the subsequent belt frame 200 at a lower height after leaving the second channel body 104, while leaving upper space for the entry of the upper belt segment. This achieves three-dimensional misalignment and smooth connection of the running paths of the upper and lower belt segments within a limited height, providing a stable spatial guiding foundation for continuous belt operation without stopping the machine.

[0033] The first idler 109 and the second idler 110 both adopt a three-roller structure, which can support the upper belt segment while applying a flattening force to the upper belt segment, keeping the upper belt segment flat and unfolded in the width direction. The third idler 111 adopts a single idler structure, which only provides downward steering guidance for the lower belt segment. The structure is simple and adaptable to the operating characteristics of the return section of the lower belt segment.

[0034] It should be noted that, Figure 1 Arrow c indicates the inlet end of the first towing trough 103, and arrow d indicates the outlet end of the first towing trough 103. Arrow e indicates the outlet side of the second towing trough 104.

[0035] Combination Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the assembly fixture 100 further includes a first anti-deviation idler roller 112, which is rotatably mounted on the frame 101. The first anti-deviation idler roller 112 is located on the side of the first idler roller 109 away from the inlet end of the first channel body 103. A plurality of first anti-deviation idler rollers 112 are spaced apart to limit the upper belt segment.

[0036] By arranging multiple first anti-deviation idlers 112 at intervals on the frame 101, and positioning the first anti-deviation idlers 112 on the side of the first idler 109 away from the inlet end of the first channel body 103, the upper belt segment is constrained before entering the first channel body 103 and during the initial stage of operation. When the upper belt segment experiences slight deviation, the edge of the upper belt segment will touch the first anti-deviation idler 112. Through the rolling contact and squeezing action between the first anti-deviation idler 112 and the belt edge, the deviation trend is suppressed at the initial stage, thereby allowing the upper belt segment to smoothly enter the first channel body 103, improving the stability and safety of belt operation, and providing a reliable guarantee for continuous assembly operations without stopping the machine.

[0037] For example, there are two first anti-deviation idlers 112, which are respectively located on opposite sides of the inlet end of the first channel body 103.

[0038] Combination Figure 1 and Figure 2 As shown, in some embodiments, the assembly fixture 100 further includes a second anti-deviation idler roller 113, which is rotatably mounted on the frame 101. The second anti-deviation idler roller 113 is located between the third idler roller 111 and the outlet side of the second channel body 104. A plurality of second anti-deviation idler rollers 113 are spaced apart to limit the movement of the lower belt segment.

[0039] By setting multiple spaced-apart second anti-deviation idlers 113 on the frame 101 and positioning them between the third idler 111 and the outlet side of the second channel body 104, the lower belt segment receives a final constraint before it detaches from the second channel body 104 and enters the bottom belt flat idler 204 of the subsequent belt frame 200. When the lower belt segment experiences slight deviation in this section, its edge touches the second anti-deviation idler 113, and the rolling contact and squeezing action promptly corrects the deviation, allowing the lower belt segment to smoothly leave the assembly fixture 100 and smoothly transition onto the bottom belt flat idler 204. This arrangement effectively prevents the lower belt segment from deviating, derailing, or overturning on the outlet side of the second channel body 104, maintaining the path accuracy and operational stability of the lower belt segment during continuous operation without stopping the machine.

[0040] For example, there are two second anti-deviation idlers 113, which are respectively disposed on opposite sides of the outlet side of the second channel body 104.

[0041] Combination Figure 1 and Figure 2 As shown, in some embodiments, the first channel body 103 is formed by a first base plate 114, first side plates 115 respectively connected to both sides of the first base plate 114, and a first cover plate 116 covering the top of the first side plates 115. The first side plates 115 are connected to the frame 101.

[0042] The first base plate 114, the first side plate 115, and the first cover plate 116 together form the first channel body 103, within which the upper belt section runs. The first channel body 103 isolates the running upper belt section from the external work area, ensuring operational safety when assembling the belt frame 200 without stopping the upper belt section.

[0043] Combination Figure 1 and Figure 2As shown, in some embodiments, the second channel body 104 is formed by a second base plate, second side plates 117 respectively connected to both sides of the second base plate, and a second cover plate 118 covering the top of the second side plates 117. The second base plate and the second side plates 117 are respectively connected to the frame 101.

[0044] The second base plate, the second side plate 117, and the second cover plate 118 together form the second channel body 104, within which the lower belt section runs. The second channel body 104 provides bottom support, lateral limiting, and top constraint for the lower belt section, ensuring that it does not dislodge or overturn during the movement of the assembly fixture 100, and maintains stable operation at all times.

[0045] For example, the first channel body 103 is located above the second channel body 104. The guide plate 105 and the bottom beam 102 together define the slide groove 106. The support 201 of the belt frame 200 is located in the slide groove 106, and its two side legs are located on both sides of the width direction of the second channel body 104. The top of the support 201 is lower than the bottom of the first channel body 103. When the assembly fixture 100 moves forward, the belt frame 200 slides backward relative to the assembly fixture 100 along the slide groove 106. The three upper rollers 203 pass under the first channel body 103, and the bottom flat rollers 204 pass under the second channel body 104, so that the belt frame 200 can slide out smoothly and land automatically.

[0046] Combination Figures 1 to 3 As shown, in some embodiments, the second channel body 104 is spaced apart from the bottom beam 102, so that the inlet side of the second channel body 104 is suspended. Furthermore, the inlet side of the second channel body 104 is located below the outlet end of the first channel body 104.

[0047] By spacing the second channel body 104 from the bottom beam 102, the inlet side of the second channel body 104 is kept suspended, creating an open clearance space between the bottom beam 102 and the second channel body 104. When the assembly fixture 100 is pulled forward, the support 201 of the assembled belt frame 200 slides backward relative to the assembly fixture 100 in the slide groove 106. This suspended space provides a channel for the upright legs of the support 201 to slide smoothly out from the rear of the assembly fixture 100, allowing the belt frame 200 to slide smoothly and automatically along the slide groove 106 and land steadily. This achieves synchronous and continuous operation of the belt frame 200 landing support and the forward movement of the assembly fixture 100, providing a key structural foundation for the automatic extension of the belt frame 200 without stopping the machine. By positioning the inlet side of the second channel body 104 below the outlet end of the first channel body 104, the lower belt segment is positioned at a lower height when entering the second channel body 104. This allows it to directly enter the bottom flat idler roller 204 of the subsequent belt frame 200 at a lower height after leaving the second channel body 104. At the same time, it leaves space above the upper belt segment as it moves from the outlet end of the first channel body 103 into the triple upper idler roller 203 of the subsequent belt frame 200.

[0048] It should be noted that, Figure 1 The arrow f in the figure is used to indicate the inlet side of the second towing trough 104.

[0049] Combination Figure 1 and Figure 3 As shown, in some embodiments, the assembly fixture 100 further includes a connecting lug 120, which is disposed on the bottom beam 102 and located on one side of the assembly fixture 100 in the forward direction, for connection with the traction device.

[0050] The connecting lug 120 is mounted on the bottom beam 102 for connection with traction equipment, such as material trains or tunneling machines. Through the connecting lug 120, the traction force of the traction equipment can be directly transmitted to the bottom beam 102 of the assembly fixture 100. As the basic load-bearing component of the frame 101, the bottom beam 102 can withstand large tensile forces without deformation, maintaining the structural stability and connection reliability of the assembly fixture 100 during the traction process.

[0051] Combination Figure 1 As shown, in some embodiments, the assembly fixture 100 also includes a pedestrian bridge 119, which spans the frame 101 and is located on one side of the assembly fixture 100 in the direction of travel, for the passage of operators.

[0052] By setting up a pedestrian overpass 119 on the frame 101, a safe and convenient passage is provided for operators between the two sides of the assembly fixture 100, so that operators can travel back and forth between the two sides of the assembly fixture 100 without crossing the running conveyor belt, which helps to improve the convenience of non-stop operation and personnel safety.

[0053] The working principle of the assembly tool 100 in this embodiment for assembling the belt frame 200 is as follows.

[0054] Assembly fixture 100 is connected to traction equipment via connecting lug 120.

[0055] The upper and lower belt sections of the conveyor belt machine operate within the first channel body 103 and the second channel body 104, respectively. Except for the openings for the upper and lower belt sections to enter and exit, both the first and second channel bodies 103 and 104 are enclosed by sheet metal to form a protective structure, isolating the running belts from the working area. The inlet end of the first channel body 103 is equipped with a first idler roller 109, and the outlet end is equipped with a second idler roller 110, which support and guide the upper belt section entering and exiting the first channel body 103, reducing friction between the upper belt section and the first channel body 103. The outlet side of the second channel body 104 is equipped with a third idler roller 111, which supports and guides the lower belt section exiting the second channel body 104, reducing friction between the lower belt section and the second channel body 104.

[0056] During belt operation, operators assemble the belt frame 200 inside the assembly fixture 100. The belt frame 200 consists of one support 201, two longitudinal beams 202, two triple upper idlers 203, and one bottom flat idler 204. The assembled belt frame 200 is integrally connected to the previous belt frame 200 that has been placed on the ground and does not move with the fixture. When the traction equipment pulls the fixture forward, the two upright legs of the support 201 slide backward relative to the assembly fixture 100 along the slide groove 106 under the limiting action of the slide groove 106. The suspended end of the second channel body 104 provides clearance for the support 201 to slide out of the assembly fixture 100. After the belt frame 200 has completely slid out and landed, the triple upper idlers 203 support the upper belt section, and the bottom flat idler 204 supports the lower belt section, thus realizing the assembly and installation of one belt frame 200. This process is repeated to complete the continuous assembly and installation of multiple belt frames 200 during belt operation.

[0057] If the upper belt segment experiences a slight deviation, its edge will touch the first anti-deviation idler 112. The squeezing action between the first anti-deviation idler 112 and the belt edge will suppress the deviation and maintain the smooth operation of the upper belt end. If the lower belt segment experiences a slight deviation, its edge will touch the second anti-deviation idler 113. The squeezing action between the second anti-deviation idler 113 and the belt edge will suppress the deviation and maintain the smooth operation of the lower belt end.

[0058] In practical applications, the assembly fixture 100 for the belt conveyor can be matched with self-moving tail and other equipment to realize the matching of tunneling face equipment. It can be connected to existing equipment by rigid connection or by hydraulic cylinder.

[0059] This application solves the problems of large size, inconvenient installation and retraction, and poor flexibility of self-moving tail telescopic frame systems. It only requires adding the belt frame assembly tool 100 behind the traditional material train at the tunneling face, along with a telescopic conveyor belt machine, to realize the assembly of the belt frame 200 and the extension of the tail during belt operation.

[0060] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
