Description

Technical Field

[0001] This utility model relates to the field of steel wire rope bucket elevator conveyor belt production technology, and in particular to a novel joint clamp for steel wire rope bucket elevator conveyor belts. Background Technology

[0002] Steel wire rope bucket elevator conveyor belt is a type of conveyor belt used in bucket elevators, mainly for the vertical transport of materials. It is made of special steel wire rope material, which has extremely high strength and elongation, can withstand large loads, and has good fatigue resistance and corrosion resistance, making it suitable for long-term use.

[0003] Since the length of a single conveyor belt is limited, it needs to be connected during use. A special connector device is required for connection. For example, the special clamp for connecting bucket elevator belts disclosed in the applicant's previous patent CN208814017U is used to clamp and fix the clamp to the end of the conveyor belt by the cooperation of nuts and washers. Then, glue is injected into the outer cover. After the glue solidifies, the sealing cover is put on to realize the connection operation of the conveyor belt.

[0004] However, after long-term use and observation, the applicant found that the joint method still has some shortcomings: due to the poor compatibility between the glue and the wire rope, if the load of the wire rope bucket elevator is large or the glue ages, the joint is prone to loosening and becoming unstable, and the wire rope will be pulled out of the clamp, which will lead to the belt falling off, posing a certain safety hazard.

[0005] Therefore, the existing conveyor belt splicing methods need to be improved. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model discloses a novel joint clamp for a wire rope bucket elevator conveyor belt, including a conveyor belt, an inner clamping block, an outer clamping block, a first bolt, a first nut, and a positioning box. An outer clamping block is provided on each side of the inner clamping block, and a conveyor belt is provided between the inner clamping block and the outer clamping blocks on both sides. The outer clamping blocks on both sides are connected by the first bolt and the first nut, and the first bolt passes through the inner clamping block. The end of the wire rope in the conveyor belt extends into the positioning box. An alloy layer is provided in the positioning box, and the alloy layer fixes the end of the wire rope in the positioning box.

[0007] Furthermore, the ends of the wire rope are in a detached state.

[0008] Furthermore, a pressure plate is provided on the outer end face of the positioning box, and connecting plates are provided on both sides of the pressure plate. One end of the connecting plate is connected through a first bolt, and the other end is connected to the pressure plate through a second bolt and a second nut.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention uses inner and outer clamping blocks to clamp and fix the conveyor belt, and uses an alloy layer inside the positioning box to weld and fix the end of the steel wire rope, so that the end of the steel wire rope and the alloy layer are fused together, thereby making the conveyor belt joint more stable and firm, and improving the safety of the belt.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0017] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0018] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 As shown, the novel joint clamp for the wire rope bucket elevator conveyor belt in this embodiment includes a conveyor belt 1, an inner clamping block 2, an outer clamping block 3, a first bolt 4, a first nut 5, and a positioning box 6. An outer clamping block 3 is provided on each side of the inner clamping block 2, and a conveyor belt 1 is provided between the inner clamping block 2 and the outer clamping blocks 3 on both sides. The outer clamping blocks 3 on both sides are connected by the first bolt 4 and the first nut 5, and the first bolt 4 passes through the inner clamping block 2, thereby firmly clamping the conveyor belt 1 in the middle.

[0020] The end of the steel wire rope 7 inside the conveyor belt 1 extends into the positioning box 6, and the end of the steel wire rope 7 is in a broken state. Since the steel wire rope 7 is made of several strands of fine steel wire twisted together, its end is broken and scattered during splicing so that it is evenly distributed in the positioning box 6.

[0021] The positioning box 6 is provided with an alloy layer 8. The formation process of the alloy layer 8 is as follows: molten lead-antimony alloy is injected into the positioning box 6, and the ends of the broken steel wire rope 7 are fully wrapped. After the lead-antimony alloy is completely cooled and solidified, the alloy layer 8 is formed.

[0022] Compared with existing glue joints, the alloy layer 8 is fused to the end of the steel wire rope 7, making the conveyor belt joint more stable and secure, and improving the safety of the belt.

[0023] A pressure plate 9 is provided on the outer end face of the positioning box 6. Connecting plates 10 are provided on both sides of the pressure plate 9. One end of the connecting plate 10 is connected through the first bolt 4, and the other end is connected to the pressure plate 9 through the second bolt 11 and the second nut 12, thereby fixing the positioning box 6 to the outer clamping blocks 3 on both sides.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
