Description

Technical Field

[0001] This utility model relates to the technical field of shearing machines, and in particular to a shearing device for rubber pads in mines. Background Technology

[0002] In mining, construction, and industrial manufacturing, sheet materials such as rubber mats and thin metal sheets often need to be cut to meet different sizes and applications. Currently, lever-type manual shearing tools are commonly used to cut these materials. These tools are typically simple in structure, easy to carry, and suitable for complex work environments and situations where power supply is difficult, thus they are widely used.

[0003] However, existing manual cutting devices generally rely on operators' experience or external tools (such as measuring tapes) to judge and position the material length, making it impossible to achieve rapid and precise adjustment of the cutting length. This can easily lead to cumbersome operation, inconsistent cutting dimensions, and even repeated measurements and rework when materials need to be cut on demand (such as temporary size changes or adaptation to site conditions), seriously affecting work efficiency and product qualification rate.

[0004] In view of this, the inventors specifically designed a shearing device for rubber pads in mines, which led to this invention. Utility Model Content

[0005] The purpose of this application is to provide a mine gas cylinder transport vehicle that at least solves the problem that existing manual shearing devices cannot achieve rapid and precise adjustment of the shearing length, resulting in cumbersome operation and inconsistent shearing dimensions.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This application provides a shearing device for rubber mats in a mining area, characterized in that it includes a base and a mounting plate. The base is provided with a lower blade, and the mounting plate is provided with an upper blade. The upper blade includes a hinged end hinged to the mounting plate and a movable end that rotates around the hinged end. The movable end is provided with a pressing component for driving the upper blade to shear with the lower blade. The pressing component includes a handle rotatably connected to the mounting plate and two elbow blocks for connecting the handle and the upper blade. The elbow blocks are located on both sides of the handle, with one end of the elbow block rotatably connected to the handle and the other end rotatably connected to the upper blade. The lower blade is detachably provided with a distance measuring component for measuring the length of the object being cut.

[0008] In a further embodiment, the ranging component includes a placement plate, on which a slider for stopping and positioning the length of the object to be cut is slidably disposed.

[0009] In a further embodiment, the placement plate includes a fixing part and a straight part. The fixing part is used for detachable connection between the placement plate and the lower blade, and the straight part is used for placing and positioning the workpiece.

[0010] In a further embodiment, an inverted T-shaped groove for sliding the slider is provided through one end face on both sides of the straight portion.

[0011] In a further embodiment, the slider includes a sliding part, a stop part, and a connecting part; the sliding part is used to slide within the groove; the stop part protrudes from the upper end face of the straight part and is used to stop the workpiece; the connecting part is used to connect the sliding part and the stop part.

[0012] In a further embodiment, a flange is formed opposite to the end face of the groove near the straight portion; a slot for engaging the flange is provided on one side of the connecting portion.

[0013] In a further embodiment, a magnetic suction element is fixedly provided on the end face of the fixing part that contacts the lower blade.

[0014] In a further embodiment, the straight section is provided with scale lines parallel to the direction of the groove.

[0015] In a further embodiment, a cover is provided on the end face through which the slide groove passes to prevent the slider from falling.

[0016] In a further embodiment, an extension handle is attached to the end of the handle.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] By adding a detachable ranging component to the lever-type shearing structure, and combining it with a slider structure with sliding positioning function, the length of the material being cut can be quickly and accurately adjusted, avoiding the problems of large errors and cumbersome operation caused by the reliance on manual measurement in traditional shearing devices. In addition, the combined use of the slide and scale lines improves the visualization and repeatability of the shearing process. The overall device has a compact structure and is easy to assemble and disassemble, maintaining the portability of manual tools while significantly improving efficiency and shearing accuracy.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0034] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0035] like Figure 1 and Figure 2 As shown, this application provides a shearing device for rubber pads in a mine, including a base 11 and a mounting plate 12 mounted on the base 11. A lower blade 13 is fixedly disposed on the base 11, and an upper blade 14 is disposed on the mounting plate 12. The upper blade 14 has a hinged end 15 at one end, which is hinged to the mounting plate 12 via a pin, and a movable end 16 at the other end. The movable end 16 can rotate around the hinged end 15 under pressure, thereby realizing a shearing action with the lower blade 13.

[0036] To achieve the lever transmission function of the shearing operation, a pressing assembly 17 is provided on the movable end 16. This pressing assembly 17 consists of a handle 172 and two elbow blocks 171 distributed on both sides. The middle part of the handle 172 is rotatably connected to the mounting plate 12 via a pin. The tail end of the handle 172 can be detached or extended with an extension handle 3 as needed to enhance the operating leverage and reduce manual labor. Each elbow block 171 is connected to the handle 172 at one end via a pin and to the upper blade 14 at the other end via a pin. During the downward pressing of the handle 172, the elbow block 171 rotates, driving the upper blade 14 downward to form a shearing engagement with the lower blade 13. This structure forms a typical double-elbow-joint transmission mechanism, which has the advantages of stable transmission, large shearing force, and high efficiency, making it suitable for precise shearing of highly elastic materials such as rubber pads.

[0037] like Figure 2 and Figure 3 As shown, to overcome the drawback of traditional shearing devices that cannot quickly measure the cutting length, a distance measuring component 2 is detachably installed on the lower blade 13. This distance measuring component 2 includes a placement plate 21 arranged along the extending direction of the lower blade 13. The placement plate 21 is used to support the workpiece, ensuring it conforms to the shearing path and controlling the material entry length. The placement plate 21 includes a fixing part 211 and a straight part 212. The fixing part 211 is fixedly connected to the lower blade 13 by screws or magnetic attraction 4, making assembly and disassembly convenient. The straight part 212 is used to place the workpiece and provide a straight guide.

[0038] Figure 4 to Figure 6 As shown, to achieve on-demand fixed-length positioning, an inverted T-shaped groove 23 is provided through the straight portion 212, and a slider 22 is slidably installed within the groove 23. The slider 22 is used to abut against the front end of the workpiece, thereby limiting its length. The slider 22 structure includes: a sliding portion 221 located within the groove 23 for translating along the direction of the groove 23; a stop portion 222 protruding from the upper surface of the straight portion 212 for contacting the end of the workpiece and restricting its further advancement; and a connecting portion 223 connecting the two. To prevent the slider 22 from falling off when sliding to the end, a cover 6 structure is also designed at the end of the groove 23. The cover 6 can be detached and opened for easy installation or cleaning of the slider 22. A bayonet 224 structure is provided on one side of the connecting portion 223 of the slider 22, which engages with the flanges 231 provided on both sides of the groove 23 to ensure stable sliding and prevent it from falling off.

[0039] In addition, to improve the intuitiveness of positioning, the surface of the flat part 212 is also provided with scale lines 5 along the direction of the slide groove 23, so that the user can directly read the predetermined length of the cut object without the need for separate measurement, which improves the convenience and accuracy of operation.

[0040] Through the aforementioned structural combination, this cutting device not only inherits the advantages of simple structure and reliable operation of lever-type manual tools, but also achieves rapid fixed-length cutting through the detachable distance measuring component 2. This overcomes the defect of repeated measurement required in the traditional cutting process, significantly improving work efficiency and dimensional consistency, and is particularly suitable for the actual needs of multi-specification cutting in on-site operations.

[0041] In summary, the mining rubber pad shearing device proposed in this application has a reasonable structure and is easy to operate. It achieves efficient shearing function through a lever-type shearing mechanism with upper and lower blades 13 working together. Combined with the detachable distance measuring component 2 and the slider 22 stop structure, it not only improves the precise control of the shearing length, but also enhances the adaptability and flexibility of the device in field use, solving the technical problems of existing technologies that rely on manual measurement of shearing length, resulting in low efficiency and large errors.

[0042] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
