Description

Technical Field

[0001] This invention belongs to the field of slurry transportation technology, and more specifically, it relates to a device for preventing belt deviation and material slippage during the transportation of clay grouting materials. Background Technology

[0002] During the clay slurry preparation for the treatment of water-damaged ground areas, it is necessary to rely on belt conveyors to transport the clay to the grouting station. When using belt conveyors to transport clay materials, belt deviation often occurs, causing the material to slide down and leak.

[0003] Traditional methods for preventing belt conveyors from deviating include: adjusting idler rollers, gravity adjustment, vertical roller adjustment, shim adjustment, cleaning idler rollers, adjusting tension devices, reducing resistance, bracket correction, belt repair, and tensioning devices. However, using these methods to prevent deviating significantly increases the manufacturing and transportation costs of the devices. Furthermore, their actual effectiveness in preventing deviating is poor, and material leakage still occurs, resulting in low material utilization. Summary of the Invention

[0004] The purpose of this invention is to provide a device for preventing belt deviation and material slippage during the transportation of clay grouting materials, aiming to solve the technical problems of high cost, poor anti-deviation effect, and low material utilization rate of existing anti-deviation transportation devices.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a device for preventing conveyor belt deviation and material slippage during the transportation of clay grouting materials, comprising:

[0006] A conveying assembly includes a conveyor belt, with its two ends extending to a clay pit and a grouting station, respectively; the conveying direction of the conveyor belt is defined as a first direction, and the horizontal direction perpendicular to the conveyor belt is defined as a second direction;

[0007] Two sets of slides are symmetrically arranged on both sides of the conveyor belt along the second direction, and are both parallel to the conveyor belt; each slide contains multiple rollers that slide at intervals along the first direction; and

[0008] Multiple sets of tensioning members correspond one-to-one with multiple rollers; one end of each set of tensioning members is connected to the conveyor belt, and the other end is limited on the corresponding roller.

[0009] When the conveyor belt is filled with clay material, the middle of the conveyor belt is concave downward along the second direction, and the two sides of the conveyor belt are tensioned and limited in the corresponding rollers by multiple sets of tensioning members, and the rollers rotate in the slide along the first direction with the conveyor belt.

[0010] In one possible implementation, the roller has a roller shaft on the side facing the conveyor belt, and the roller is connected to the tensioning member through the roller shaft.

[0011] In some embodiments, when the conveyor belt is unloaded, the roller shaft is at the same height as the side edge of the conveyor belt, or the roller shaft is located diagonally above the side edge of the conveyor belt.

[0012] For example, the slide rail includes a first slide groove and a second slide groove arranged sequentially along the second direction. The roller rotates within the first slide groove, and the roller shaft extends out from the second slide groove and slides within the second slide groove. The upper and lower side walls of the second slide groove are placed between the upper and lower side walls of the first slide groove, and a stepped surface is formed at the junction of the first slide groove and the second slide groove to limit the roller.

[0013] In some embodiments, the roller shaft is provided with a first ring facing the extension end of the conveyor belt, and the tensioning member is wound and fixed on the first ring.

[0014] In one possible implementation, the conveyor belt is provided with multiple sets of fastening components spaced apart along the first direction, and each set of fastening components corresponds to a roller at both ends along the second direction. The tensioning member is connected to the conveyor belt through the fastening components.

[0015] In some embodiments, the fastening assembly includes two fastening plates symmetrically arranged on the conveyor belt, the two fastening plates being clamped on the upper and lower sides of the conveyor belt and both being connected to the tensioning member.

[0016] For example, one end of the tensioning member is fixed to one of the fastening plates, and the other end passes through the connection between the tensioning member and the roller and is fixed to the other fastening plate.

[0017] For example, the upper fastening plate is provided with a plurality of protrusions spaced apart along the second direction.

[0018] In one possible implementation, the tensioning member is also provided with an adjusting locking buckle.

[0019] Compared with the prior art, the solution shown in this application has the following advantages: when clay material is placed on a conveyor belt, the middle of the conveyor belt is concave under the gravity of the clay material. Since this device has slides on both sides of the conveyor belt, and the side of the conveyor belt is tightened by one end of the tensioning member, while the other end is limited in the slide by the roller, the friction of the limiting end is reduced, so that both sides of the conveyor belt are tightened under the action of the tensioning member, thereby forming an arc-shaped structure with a lower middle and higher sides. This prevents the clay material from deviating and leaking during the transportation process, thereby improving the utilization rate and conveying efficiency of the clay material. In addition, the structure of the tensioning member, roller and slide used in this application is simple, which can effectively reduce the manufacturing and transportation costs.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0032] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0034] It should be noted that, for ease of understanding, this application uses the appendix. Figure 1 Arrow A in the diagram indicates the first direction, and uses an attached... Figure 2 The direction indicated by arrow B in the diagram is the second direction.

[0035] Please refer to the following: Figures 1 to 4 The present invention describes a device for preventing conveyor belt misalignment and material slippage during the transportation of clay grouting materials. The device includes a conveyor assembly 1, two sets of chute 2, and multiple sets of tensioning members 4. The conveyor assembly 1 includes a conveyor belt 11, with both ends extending to the clay yard and the grouting station, respectively. The conveying direction of the conveyor belt 11 is defined as the first direction, and the horizontal direction perpendicular to the conveyor belt 11 is defined as the second direction. The two sets of chute 2 are symmetrically arranged on both sides of the conveyor belt 11 along the second direction, and are parallel to the conveyor belt 11. Each chute... Multiple rollers 3 slide at intervals along the first direction within the slide 2; multiple sets of tensioning members 4 correspond one-to-one with the multiple rollers 3; one end of each set of tensioning members 4 is connected to the conveyor belt 11, and the other end is limited on the corresponding roller 3; wherein, when clay material is contained on the conveyor belt 11, the middle of the conveyor belt 11 is concave downward along the second direction, and both sides of the conveyor belt 11 are tensioned and limited in the corresponding rollers 3 by multiple sets of tensioning members 4, and the rollers 3 rotate in the slide 2 along the first direction with the conveyor belt 11.

[0036] Specifically, the conveying assembly 1 also includes two drive wheels 12 respectively located near the clay field and the grouting station, and a drive motor for driving one of the drive wheels 12 to rotate. One drive wheel 12 connected to the drive motor is the driving wheel, and the other drive wheel is the driven wheel. The conveyor belt 11 is wound between the main drive wheel and the driven wheel to form a ring structure encircling the driving wheel and the driven wheel.

[0037] It should be understood that the slide 2 is also a ring structure arranged parallel to the conveyor belt 11, and the two slides 2 are respectively arranged on both sides of the conveyor belt 11. When the conveyor belt 11 moves, the tensioning member 4 connected to the conveyor belt 11 drives the roller 3 to rotate synchronously in the slide 2, so as to reduce the friction between the tensioning member 4 and the slide 2, and at the same time ensure that the tensioning member 4 is always tensioned on the side of the conveyor belt 11.

[0038] Furthermore, specifically, the slide 2 includes a first slide 2 and a second slide 2 arranged at intervals, and an annular slide 2 connecting the two ends of the first slide 2 and the second slide 2; in order to support the first slide 2 and the second slide 2, a support frame 23 is also provided between the first slide 2 and the second slide 2. The support frame 23 can specifically be a support column, used to stably support the slide 2 on both sides of the conveyor belt 11.

[0039] Optionally, the tensioning member 4 can be any one of tension cable, connecting rope, wire rope or tensioning belt, capable of tightening the side of the conveyor belt 11 and limiting the other end through the roller 3.

[0040] It should be understood that each set of tensioning members 4 corresponds to a roller 3, and the roller 3 is confined within one set of slide rails 2 near the tensioning member 4, and rotates along the extension direction of the slide rail 2 with the conveyor belt 11.

[0041] It is important to understand that when the conveyor belt 11 deviates in the vertical and horizontal directions, it will be constrained by the roller 3 and the tensioning member 4, so that the conveyor belt 11 always remains in a "non-moving" balanced state. Under this condition, the horizontal and vertical deviation of the conveyor belt 11 can be basically ignored, achieving a "zero" deviation effect, avoiding the occurrence of material leakage, and improving material transportation efficiency and material utilization.

[0042] The device provided by this invention for preventing conveyor belt deviation and material slippage during the transportation of clay grouting materials, compared with the prior art, when the clay material is placed on the conveyor belt 11, the middle part of the conveyor belt 11 is concave downward under the gravity of the clay material. Since this device is provided with slide rails 2 on both sides of the conveyor belt 11, and the side of the conveyor belt 11 is tightened by one end of the tensioning member 4, and the other end is limited in the slide rail 2 by the roller 3, the friction of the limiting end is reduced, so that the two sides of the conveyor belt 11 are tightened under the action of the tensioning member 4, thereby forming an arc-shaped structure with a low middle and high sides of the conveyor belt 11, thereby preventing the clay material from deviating and leaking during the transportation process, and thus improving the utilization rate and conveying efficiency of the clay material; and the structure of the tensioning member 4, roller 3 and slide rail 2 used in this application is simple, which can effectively reduce the manufacturing and transportation costs.

[0043] Please see Figure 2 and 3 In some possible embodiments, the roller 3 is provided with a roller shaft 31 on the side facing the conveyor belt 11, and the roller 3 is connected to the tensioning member 4 through the roller shaft 31.

[0044] By setting the roller shaft 31 and extending the roller shaft 31 to one side of the conveyor belt 11, the connection between the roller 3 and the tensioning member 4 extends out to the slide 2, so as to avoid mutual interference between the tensioning member 4 and the slide 2 and affect the tensioning effect of the tensioning member 4.

[0045] Please see Figure 3 In some embodiments, when the conveyor belt 11 is unloaded, the roller shaft 31 is at the same height as the side edge of the conveyor belt 11, or the roller shaft 31 is located diagonally above the side edge of the conveyor belt 11.

[0046] By ensuring that the height of the roller shaft 31 is not lower than the height of both sides of the conveyor belt 11, the roller shaft 31 can lift both sides of the conveyor belt 11 upward with the help of the tensioning member 4, so that the two sides of the conveyor belt 11 are higher than the middle, thereby further preventing the clay material from running off the conveyor belt 11 and causing material leakage.

[0047] Please see Figure 3 and 4 For example, the slide 2 includes a first slide groove 21 and a second slide groove 22 arranged sequentially along the second direction. The roller 3 is rotatably located in the first slide groove 21, and the roller shaft 31 extends out from the second slide groove 22 and slides in the second slide groove 22. The upper and lower side walls of the second slide groove 22 are placed between the upper and lower side walls of the first slide groove 21, and a step surface for limiting the roller 3 is formed at the junction of the first slide groove 21 and the second slide groove 22.

[0048] By setting a first slide groove 21, the roller 3 can roll within the first slide groove 21; by setting a second slide groove 22 and restricting the upper and lower side walls of the second slide groove 22 to be placed between the upper and lower side walls of the first slide groove 21, a stepped surface is formed at the junction of the first slide groove 21 and the second slide groove 22, thereby limiting the roller 3 within the first slide groove 21 and preventing the roller 3 from deviating from the first slide groove 21 from the stepped surface.

[0049] Please see Figure 4 In some embodiments, the roller shaft 31 is provided with a first ring 32 at the extended end facing the conveyor belt 11, and the tensioning member 4 is wound and fixed on the first ring 32.

[0050] By setting the first ring 32, it is convenient to pass the tensioning member 4 through the first ring 32 so as to realize the connection between the tensioning member 4 and the roller shaft 31.

[0051] Please see Figures 1 to 3 In some possible embodiments, multiple sets of fastening components are spaced apart along the first direction on the conveyor belt 11, and each set of fastening components corresponds to a roller 3 at both ends along the second direction. The tensioning member 4 is connected to the conveyor belt 11 through the fastening components.

[0052] By setting up a fastening assembly, the end of the tensioning member 4 is connected to the conveyor belt 11; and by setting up a fastening assembly, the rollers 3 on both sides and the tensioning member 4 are arranged opposite to each other, so that the two sides of the conveyor belt 11 are symmetrically tensioned, thereby improving the stability of the conveyor belt 11 during transportation.

[0053] Optionally, the fastening assembly can be a fixing plate, which is fixedly connected to the conveyor belt 11, and the fixing plate has second rings at both ends. One end of the tensioning member 4 passes through the first ring 32, and the other end passes through the second ring.

[0054] Please see Figure 3 In some embodiments, the fastening assembly includes two fastening plates 5 arranged symmetrically on the conveyor belt 11. The two fastening plates 5 are clamped on the upper and lower sides of the conveyor belt 11 and are both connected to the tensioning member 4.

[0055] Two snap-fit ​​plates 5 are symmetrically arranged at the top and bottom to clamp the conveyor belt 11, thereby improving the stability of the connection between the snap-fit ​​plates 5 and the conveyor belt 11. Optionally, the two snap-fit ​​plates 5 can be detachably connected at both ends along the second direction by threaded connectors to clamp the conveyor belt 11.

[0056] Please see Figure 1 For example, one end of the tensioning member 4 is fixed to one of the fastening plates 5, and the other end passes through the connection between the tensioning member 4 and the roller 3 and is fixed to another fastening plate 5.

[0057] By connecting the tensioning member 4 to the upper and lower fastening plates 5 respectively, the stability of the connection between the tensioning member 4 and the fastening plates 5 is improved.

[0058] Specifically, one end of the tensioning member 4 is fixed to the upper fastening plate 5, and the other end passes through the first ring 32 on the roller shaft 31 and is fixed to the lower fastening plate 5.

[0059] Please see Figure 3 For example, the upper fastening plate 5 is provided with a plurality of protrusions 51 spaced apart along the second direction.

[0060] By setting multiple protrusions 51, the object is prevented from sliding down the ramp quickly during transport, achieving the same deceleration effect as a speed bump on a highway, reducing the sliding speed of the clay material on the conveyor belt 11, and improving the stability of material transport.

[0061] Please see Figure 4 In some possible embodiments, the tensioning member 4 is also provided with an adjusting locking buckle 41. The length of the tensioning member 4 is adjusted by setting the adjusting locking buckle 41, thereby adjusting the tension of the tensioning member 4. It should be noted that the adjusting structure and working principle of the adjusting locking buckle 41 are existing technologies and will not be described in detail here.

[0062] Furthermore, to improve the load-bearing capacity of the conveyor belt 11, idlers, idler supports, and a drive device can be installed at the bottom of the conveyor belt 11. The drive device drives the idlers to rotate, thereby assisting the conveyor belt 11 in its transport operation. The driving principles of the idlers, idler supports, and drive device are all existing technologies. Optionally, the idlers can be arranged in one row, spaced apart at the bottom of the conveyor belt 11 along the conveying direction. Alternatively, two rows of idlers can be symmetrically arranged along a second direction, with each row of idlers spaced apart at the bottom of the conveyor belt 11 along the conveying direction to assist the conveyor belt 11 in its transport operation. Optionally, the two rows of idlers can be arranged horizontally along the second direction, or the two rows of idlers can be slightly inclined towards the middle of the conveyor belt 11 to accommodate the downward curvature of the conveyor belt 11, ensuring that the conveyor belt 11 can still operate normally when carrying heavy goods.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
