Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments and features of this utility model can be combined with each other.

[0028] The following description sets forth many specific details to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments described in the specification are only some embodiments of the present invention, and not all embodiments.

[0029] like Figure 1 As shown, the belt fixing auxiliary device provided in this embodiment of the utility model includes a frame 1 and a vertical drive component 4. A traveling assembly 2 is provided at the bottom of the frame 1. The frame 1 can move along a direction perpendicular to the conveying direction of the belt 52, i.e., along a horizontal direction, via the traveling assembly 2. The frame 1 can travel on a supporting surface such as the ground, or on the support plate 56 of the bucket elevator 5, and can be designed according to actual needs. A connecting component 3 is provided on the frame 1 for detachable connection with the belt 52. The connection method between the connecting component 3 and the belt 52 is unrestricted and can be designed according to actual needs. The vertical drive component 4 is disposed on the frame 1 and is used to drive the connecting component 3 to move along a vertical direction, thereby driving the belt 52 connected to the connecting component 3 to move upward along a vertical direction, adjusting the relative height position of the two ends of the separated belt 52 in the longitudinal direction. This provides support for lifting the belt 52 before separation and fixing the belt 52 after separation.

[0030] It is understood that the belt fixing auxiliary device provided by this utility model is used for the connection and position adjustment of the belt 52 on one side of the interface. When in use, two belt fixing auxiliary devices are used together.

[0031] Based on the belt fixing auxiliary device provided by this utility model, when replacing the head wheel 53 and anti-slip skin of the bucket elevator 5 and shortening the belt 52, two belt fixing auxiliary devices can be placed or installed on both sides of the bucket elevator 5 respectively, and connected to the belt 52 on the corresponding side through the connecting piece 3. The vertical drive piece 4 drives the connecting piece 3 to move in the vertical direction, so as to lift the height of the belt 52 on both sides of the interface before separation, eliminate the tension on the interface of the belt 52 caused by the weight of the belt 52 itself, so as to meet the disassembly requirements of the belt 52 interface. The walking component 2 drives the connecting piece 3 to move in the direction perpendicular to the conveying direction of the belt 52, so as to realize the opposite separation movement of the two ends of the belt 52 after the interface is opened, so as to meet the needs of maintenance and replacement of the head wheel 53 or wear-resistant anti-slip skin and shortening of the belt 52, providing sufficient space for it. This process does not require lowering the belt 52, which is convenient to operate, increases work efficiency, and does not require other hoisting equipment, reducing the difficulty of operation and facilitating safety management.

[0032] In some implementations, such as Figure 1 As shown, a crossbeam 11 is provided on the frame 1, the crossbeam 11 extends in the horizontal direction, the connecting piece 3 is provided on the crossbeam 11, and the vertical drive piece 4 is used to drive the crossbeam 11 to move in the vertical direction.

[0033] In this design, the vertical drive component 4 drives the crossbeam 11 to move in the vertical direction, which in turn drives the connecting component 3 to move in the vertical direction, increasing the convenience of driving. Multiple connecting components 3 can be set, so that one vertical drive component 4 can drive multiple connecting components 3 to move synchronously, reducing the cost of the drive component and enabling multiple connecting components 3 to move synchronously.

[0034] In some embodiments, the frame 1 includes a portal frame 12, which includes two spaced vertical rods 121 and a horizontal rod 122 connected to the top of the two vertical rods 121. The inner sides of the two vertical rods 121 of the portal frame 12 are provided with vertical guide grooves 1211. The vertical guide grooves 1211 extend in the vertical direction and the length of the vertical guide grooves 1211 is not limited. The two ends of the horizontal beam 11 are respectively slidably engaged with the two vertical guide grooves 1211, that is, the two ends of the horizontal beam 11 are respectively inserted into the two vertical guide grooves 1211 and slidably engaged with the vertical guide grooves 1211 in the vertical direction.

[0035] This design ensures that the crossbeam 11 is vertical, prevents lateral deviation, increases the accuracy of position adjustment, and enhances the smoothness and stability of the crossbeam 11's vertical movement.

[0036] In some embodiments, there are multiple connectors 3, all of which are disposed on the crossbeam 11 and slide along the length of the crossbeam 11 to facilitate adjustment of the position of the connectors 3.

[0037] In this design, multiple connectors 3 can change the distance between two adjacent connectors 3 by moving themselves, thereby enabling them to connect with belts 52 of different widths, ensuring the connection effect, and thus adapting to belts 52 of different widths, increasing the applicability of the belt fixing auxiliary device.

[0038] In some embodiments, there are three connectors 3, which can make the two ends and the middle of the belt 52 bear force during the specific operation, improve the stability of the belt 52 during the lifting and separation process, and at the same time make the belt fixing auxiliary device applicable to all width and narrow belts 52 of the hoist, thus improving the applicability.

[0039] In some embodiments, the connecting plate 32 is made of a high tensile strength flexible rubber plate, which can eliminate the influence of the bending factor of the belt 52 on the connection between the connecting plate 32 and the belt 52, improve the fit and increase the connection efficiency.

[0040] In some implementations, such as Figure 1 As shown, the bottom of the crossbeam 11 is provided with a slide rail 111, which extends along the length of the crossbeam 11, and the top of the connector 3 is provided with a groove that matches the slide rail 111.

[0041] Specifically, the slide rail 111 extends out of both sides of the crossbeam 11 along the width direction of the crossbeam 11. The top of the connector 3 is provided with a slider, and a groove is provided on the slider. The width of the groove is greater than the width of the top opening of the slider, so as to form a hook plate at the top opening of the slider, so that the top of the slider forms a C-shaped structure. The width of the groove is the same as that of the slide rail 111, and the hook plate can overlap the top of the extended end of the slide rail 111 to achieve sliding engagement.

[0042] The slide rail 111 and slide groove designed in this way have a simple structure and a firm fit, which increases the safety and convenience of use.

[0043] In some implementations, such as Figure 1 As shown, the connector 3 includes a sliding seat 31 connected to the crossbeam 11 and a connecting plate 32 disposed at the bottom of the sliding seat 31. The connecting plate 32 is provided with a plurality of connecting holes 33, and the positions of the plurality of connecting holes 33 are opposite to the mating holes 54 on the belt 52.

[0044] Specifically, the slider is located on the top of the sliding seat 31, and the sliding seat 31 slides in conjunction with the crossbeam 11 via the slider. The bottom of the sliding seat 31 has a slot, giving it a clamp-like design. The top of the connecting plate 32 is inserted into the slot. The forward-designed sliding seat 31 guides and limits the insertion of the connecting plate 32, increasing positioning accuracy and installation efficiency. The top of the connecting plate 32 is bolted to the corresponding position of the sliding seat 31, increasing ease of assembly and disassembly and facilitating the replacement of connecting plates 32 with different sized connecting holes 33, further expanding its applicability. This also increases the holding force on the connecting plate 32, reducing the probability of breakage and detachment. The mating hole 54 on the belt 52 can be a screw hole. When the connecting plate 32 is connected to the belt 52, the connecting hole 33 on the connecting plate 32 corresponds one-to-one or partially to the mating hole 54 on the belt 52. The bolt can pass through the connecting hole 33 and be inserted into the mating hole 54 to complete the connection and fixation, increasing ease of assembly and disassembly.

[0045] In some implementations, reference continues. Figure 1 The vertical drive component 4 includes an adjusting rod 41 that is vertically mounted on the crossbar 122 of the portal frame 12. The bottom end of the adjusting rod 41 is connected to the crossbeam 11. The specific connection method is not limited. For example, it can be welded, snap-fitted, or bolted. It can be designed according to actual needs. The adjusting rod 41 can drive the crossbeam 11 to move in the vertical direction.

[0046] With this design, the vertical movement of the adjusting rod 41 can drive the crossbeam 11 to move vertically, thereby driving the connecting piece 3 to move vertically, making operation convenient.

[0047] In some embodiments, the adjusting rod 41 is a screw, with its top end extending out of the crossbeam 11, and a rotating rod 42 threadedly connected to the extended end of the adjusting rod 41. That is, one end of the adjusting rod 41 passes through the crossbeam 122 and is connected to the crossbeam 11, while the other end of the adjusting rod 41 extends upward out of the crossbeam 122 and is threadedly connected to the rotating rod 42, which can be held by hand.

[0048] With this design, the position of the adjusting rod 41 in the vertical direction can be adjusted by rotating the rotary rod 42, making operation convenient.

[0049] In some embodiments, there are two adjusting rods 41, which are arranged at intervals along the extension direction of the crossbar 122 to multiply the lifting force, while also achieving the leveling of the crossbeam 11 and the balance of force during the lifting process.

[0050] In some implementations, combined Figure 1 and Figure 2 As shown, the frame 1 includes a portal frame 13 disposed at the bottom of two vertical rods 121 of the portal frame 12. The portal frame 12 includes two side frames 131 and a top frame 132 connected to the top of the two side frames 131. The top frame 132 is connected to the bottom of the vertical rods 121. The plane of the portal frame 12 is perpendicular to the plane of the portal frame 13, that is, the planes of the two portal frames 13 are parallel. The traveling assembly 2 includes multiple traveling members 21, and each portal frame 13 has a traveling member 21 at the bottom of its side frame 131.

[0051] In this design, there are four walking components 21 to facilitate the support of the frame 1 and the stability of its movement.

[0052] In some implementations, combined Figure 2 and Figure 3 As shown, the traveling member 21 includes a wheel seat 211 located at the bottom of the frame 131. The inner side of the wheel seat 211 has a horizontal slot, and rollers 212 are rotatably mounted on both sides of the slot along the vertical direction. A rolling groove 213 is formed between two rollers 212 arranged opposite each other in the vertical direction. This design allows the traveling member 21 to travel on the outer casing 51 of the bucket elevator 5. Specifically, the wheel seat 211 includes grooved rolling frames located on the upper and lower sides of the slot. Each grooved rolling frame contains two rollers 212 spaced apart. A collar is provided within the grooved rolling frame to facilitate the installation and positioning of the rollers 212. Both grooved rolling frames are connected to the bottom of the frame 131 and are spaced apart in the vertical direction, ensuring that the rollers 212 in the two grooved rolling frames correspond one-to-one in the vertical direction.

[0053] In some embodiments, the position of the grooved rolling frame on the frame 131 is adjustable. Specifically, the vertical position of the grooved rolling frame is adjusted to adjust the size of the rolling groove 213, meeting the walking requirements of the traveling component 21 on the outer shell 51 of different bucket elevators 5. The method of adjusting the position of the grooved rolling frame on the frame 131 is not limited. For example, multiple screw holes can be opened along the vertical direction on the frame 131, and bolts can be passed through the grooved rolling frame and screwed into different screw holes. This can be designed according to actual needs.

[0054] In some embodiments, two angular ear plates are provided on each of the horizontal sides of the contact surface between the grooved rolling frame and the frame 131. The angular ear plates are symmetrically distributed along the vertical axis of the frame 131. The ear plates are connected to the grooved rolling frame and the frame 131 by bolts to increase the strength of the connection.

[0055] like Figure 4 As shown ( Figure 4 The diagram shows a portion of a bucket elevator 5. The bucket elevator 5 includes a housing 51, a belt 52, and a head pulley 53. The housing 51 is also equipped with a tail pulley. The head pulley 53 and the tail pulley are spaced apart along the vertical direction. The belt 52 passes around the head pulley 53 and the tail pulley so that the belt 52 conveys the material along the vertical direction. The belt 52 has a mating hole 54 along its width direction. The mating hole 54 can be a screw hole or a through hole, which can be designed according to actual needs. The mating point of the belt 52 is provided with a fixing clamp 55 so that the mating point of the belt 52 is connected by two fixing clamps 55, which increases the convenience of disassembly and assembly and the firmness of the connection. The top of the outer shell 51 is provided with a support plate 56. The support plate 56 extends outward from the top of the outer shell 51, and the thickness of the support plate 56 matches the rolling groove 213 so that the wheel seat 211 can be supported on the support plate 56 and move on the support plate 56 through the roller 212 to change the position of the frame 1 in the direction perpendicular to the movement of the belt 52, thereby adjusting the relative position in the horizontal direction after the belt 52 port of the bucket elevator 5 is separated.

[0056] The belt fixing auxiliary device under this design can be used for lifting the belt 52 before the belt 52 interface of the bucket elevator 5 is separated, fixing the two ends after separation, and adjusting the relative position in the horizontal direction. It is convenient to operate and increases work efficiency.

[0057] The belt fixing auxiliary device provided by this utility model can quickly and effectively lift the belt 52 before the belt 52 interface is separated and fix and move both ends after separation. This solves the problem that the belt 52 cannot be fixed nearby during the replacement of parts such as the head wheel 53 and anti-slip skin of the bucket elevator 5 and the shortening of the belt 52. It saves time and effort, reduces labor intensity, workload, number of workers and personnel safety risks, improves work efficiency and safety, and reduces maintenance costs and downtime losses. Moreover, the belt fixing auxiliary device is highly versatile and can be used for auxiliary fixing of the belt 52 of bucket elevators 5 of various specifications and types, such as thick, thin, wide, narrow, straight, curved, flexible and rigid. Of course, it can also be used for other equipment with belts 52.
