Description

Technical Field

[0001] This utility model relates to the field of tooling equipment technology, and more specifically, to a belt conveyor transfer device. Background Technology

[0002] Belt conveyors are widely used in mining, metallurgy, and coal industries for transporting loose materials or packaged goods. They can be used individually or in multiple units to form horizontal or inclined conveying systems, depending on the conveying process requirements, to meet the needs of different production line layouts. Belt conveyors can continuously and evenly transport materials, ensuring the stability and safety of the production process. Due to their continuous conveying characteristics, belt conveyors can significantly improve production efficiency. Belt conveyors operate smoothly, are highly reliable, and have strong safety features, making them suitable for long-term continuous operation. Compared to other conveying equipment, belt conveyors have lower power consumption, lower operating costs, and a higher safety factor. Belt conveyors have a simple structure, are relatively easy to maintain and service, effectively reducing maintenance costs.

[0003] Prolonged operation of belt conveyors can lead to belt wear, breakage, and accidental damage, necessitating rapid belt replacement. Before replacement, the new belt needs to be transported to the site. In current technology, belt transport is typically achieved using a forklift. The forklift lifts both ends of the belt's central reel, moving it slowly. During this process, care should be taken to avoid dragging, folding, or twisting the belt. However, in actual transport, there is no direct fixation between the forklift's forks and the reel ends. During transport, relative movement occurs between the two, causing friction between the belt's sidewalls and the forklift's forks, or unwinding. This results in the belt being crushed, dragged, folded, or twisted by the forklift, causing belt damage and increasing the difficulty of belt transport.

[0004] In conclusion, how to solve the problem of easy damage during belt conveyor transport is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a belt roll transfer device, which uses a support frame that can move relative to the base to quickly support the roll, and uses the support frame to squeeze the belt from both ends to effectively prevent it from unwinding, thereby reducing the damage during the transfer process and reducing the difficulty of belt transfer.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] The core of this utility model is to provide a belt roll transfer device. By setting a support frame that can move relative to the base, the roll can be quickly supported, and the belt can be squeezed from both ends by the support frame to effectively prevent it from unwinding, thereby reducing the damage during the transfer process and reducing the difficulty of belt transfer.

[0040] Please refer to Figure 1 and Figure 2 A conveyor belt roll transfer device, comprising:

[0041] Base 1, with a wheeled walking component 4 installed at its bottom;

[0042] At least two support frames 2 are slidably mounted to the base 1, and all support frames 2 are provided with horizontally aligned and overlapping shaft holes 23 for the passage of the load-bearing shaft. The axial direction of the shaft holes 23 is consistent with the sliding direction of the support frame 2.

[0043] A drive assembly, which is fixedly mounted to the base 1, is used to drive two adjacent support frames 2 to move closer or further apart.

[0044] like Figure 1 and Figure 2 As shown, at least two sets of support frames 2 are provided on the base 1 to support the belt roll. When the belt roll is suspended above the base 1 by the lifting device and is between the two sets of support frames 2, the two sets of support frames 2 move towards each other under the action of the drive component, so that the belt roll shaft or the load-bearing shaft inside the shaft passes through the shaft hole 23. Then the device is released. At this time, the support frame 2 can support the shaft or the load-bearing shaft, that is, support the belt roll. At the same time, when the support frame 2 moves towards each other, the support frame 2 abuts against the end of the belt roll. The friction between the belt roll and the support frame 2 is used to limit the belt roll from unwinding, thereby avoiding problems such as belt dragging, folding and twisting caused by the unwinding of the belt roll during transportation.

[0045] Moreover, since the support frame 2 can move relative to or towards each other, the distance between two adjacent sets of support frames 2 can be adjusted according to the width of the belt roll, thereby meeting the needs of transporting belt rolls of different widths.

[0046] Meanwhile, a wheeled walking component 4 is set at the bottom of the base 1, so that the belt roll transfer device has the ability to move. If the wheeled walking component 4 adopts the design of universal wheels, the belt roll transfer device can be transferred under the traction of the tractor, thereby avoiding the use of forklifts for transfer and reducing the difficulty of transfer.

[0047] Alternatively, the wheeled walking assembly 4 can be driven by a hub motor, giving the belt roll's walking device self-driving capability and enabling it to transfer the belt itself, further reducing the difficulty of transfer.

[0048] In some embodiments, the drive assembly includes a lead screw 3, which is rotatably mounted to the base 1, and the length direction of the lead screw 3 is consistent with the movement direction of the support frame 2.

[0049] The lead screw 3 is connected to the support frame 2 by a thread, and the threads connecting two adjacent support frames 2 and the lead screw 3 have opposite directions of rotation;

[0050] The end of the lead screw 3 is equipped with a power drive source.

[0051] like Figure 1 and Figure 3 As shown, the driving component is a lead screw 3. The length direction of the lead screw 3 is consistent with the movement direction of the support frame 2. There are several sections of threads with opposite directions on the lead screw 3. The adjacent support frames 2 are installed with threads of different directions on the lead screw 3, so that when the lead screw 3 rotates, the adjacent support frames 2 can move towards each other or relative to each other, that is, adjust the distance between the adjacent support frames 2.

[0052] Furthermore, the lead screw 3 has a self-locking capability, which can lock the position of the support frame 2 when adjustment stops.

[0053] In use, the screw can be manually driven to rotate by setting a handwheel 31 at the end of the screw 3;

[0054] In some embodiments, a motor is provided at the end of the lead screw 3, and the motor drives the lead screw 3 to rotate, which can further increase the movement speed of the support frame 2.

[0055] In some embodiments, the drive assembly adopts a telescopic push rod design, preferably a cylinder, hydraulic cylinder, or electric telescopic rod, which can also drive the support frame 2 to move relative to the base 1 to achieve the above functions.

[0056] In some embodiments, the base 1 is provided with a plurality of positioning holes 12, and the plurality of positioning holes 12 are arranged along the sliding direction of the support frame 2.

[0057] At least one support frame 2 is provided with a limiting hole 22, which can be locked by inserting a pin into any one of the positioning holes 12.

[0058] like Figure 1and Figure 2 As shown, several sets of positioning holes 12 are provided on the base 1 along the movement direction of the support frame 2, and limiting holes 22 are provided on the support frame 2. When the position of the support frame 2 is determined, the limiting hole 22 and the corresponding positioning hole 12 are connected by a pin to lock the position of the support frame 2 and prevent the support frame 2 from continuing to move relative to the base 1.

[0059] In some embodiments, the support frame 2 has a triangular structure;

[0060] Shaft hole 23 is located at the top of the triangular structure;

[0061] A slider 21 is provided at the bottom of the triangular structure, and the slider 21 is slidably installed with the base 1.

[0062] like Figure 1 and Figure 4 As shown, the support frame 2 adopts a triangular structure, such as an equilateral triangle structure, including inclined side arms and bottom arms on both sides, and a vertical support arm is also provided between the vertex and the bottom arm to increase the stability of the support frame 2. At the same time, the lead screw 3 is installed in conjunction with the threaded hole in the middle of the bottom arm to ensure smooth power transmission.

[0063] At the same time, such as Figure 4 As shown, a slider 21 is provided at the bottom of the support frame 2, which is slidably installed with the base 1 to reduce the frictional resistance between the two and facilitate the position adjustment of the support frame 2.

[0064] In some embodiments, a bearing is coaxially fixedly disposed in the shaft hole 23, and the inner ring diameter of the bearing is not less than the shaft diameter of the load-bearing shaft.

[0065] By installing a bearing inside the shaft hole 23, when the reel or the load-bearing shaft inside the reel passes through the shaft hole 23, the rotational resistance of the reel can be reduced by the bearing, thereby reducing the resistance when the belt is unwound, and thus reducing the drag on the belt.

[0066] In some embodiments, the base 1 includes two sets of parallel seat bodies 13, and the two sets of seat bodies 13 are fixedly connected by a connector 14.

[0067] The bottom ends of the support frame 2 are slidably connected to the base 13.

[0068] like Figure 1 and Figure 2 As shown, the base 1 is composed of two sets of parallel base bodies 13 and several connecting bodies 14, which effectively ensures the stability of the base 1. Compared with the integral base 1, this solution significantly improves the weight reduction of the equipment.

[0069] In some embodiments, the length direction of the seat 13 is consistent with the sliding direction of the support frame 2, and a groove 11 is provided in the seat 13 along its own length direction;

[0070] The support frame 2 and the slide groove 11 are slidably installed.

[0071] like Figure 1 As shown, a groove 11 is provided in the extension direction of the seat body 13, and as... Figure 4 As shown, a slider 21 is provided at the bottom of the support frame 2. The slider 21 is slidably installed with the slide groove 11, which can guide the sliding trajectory of the support frame 2 and reduce the sliding resistance of the support frame 2.

[0072] In some embodiments, hooks 15 and buckles 16 are respectively provided at both ends of the base 1 for connecting multiple sets of belt roll transfer devices in series.

[0073] Hooks 15 and buckles 16 are respectively set at both ends of the base 1. By combining the hooks 15 and buckles 16, multiple belt roll transfer devices can be connected end to end, i.e., connected in series, so that multiple belt roll transfer devices can be transferred synchronously under the traction of a tractor.

[0074] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
