Description

Technical Field

[0001] This utility model relates to the field of support processing technology, and in particular to a processing jig and processing system for a flexible shield support. Background Technology

[0002] Flexible shield supports are a type of support equipment used in the mining of steeply inclined coal seams. They provide a safe working space for workers and equipment during the mining process, while also isolating the goaf from the working space.

[0003] During mining, as the working face advances, the flexible shield supports automatically move downwards along the inclined coal seam under their own weight and the pressure of the coal seam and gangue above. Workers perform coal cutting and loading operations under the protection of the flexible shield supports, and the mined coal is transported out through the space beneath the flexible shield. Meanwhile, gangue from the goaf accumulates behind the flexible shield, gradually burying it and providing resistance and guidance for its movement. Therefore, the flexible shield supports effectively isolate the goaf, prevent gangue collapses that could injure workers, and create a relatively safe working environment for them.

[0004] Currently, the manufacturing of traditional flexible shield supports requires multiple welding processes. However, the numerous welding operations involved in these processes can easily lead to misalignment of the assembly position, making the process cumbersome, inefficient, and costly. Utility Model Content

[0005] The main objective of this invention is to provide a processing fixture and processing system for a flexible shield support to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a processing fixture for a flexible shield support, comprising:

[0007] Base plate;

[0008] Two uprights are spaced apart on the base plate along the length of the base plate.

[0009] Two lower molds, each mold including a support plate and an arc plate, the support plate being connected to the top of the arc plate, the arc plate being hinged to the stand, and the arc plate being able to rotate outward about the hinge point;

[0010] The upper tire mold has a lower pressure plate, the lower pressure plate has an arc-shaped protrusion at the center of its bottom surface, and the lower pressure plate is located above the area between the two support plates.

[0011] When bending the flexible shield support, a straight flexible shield support is placed on the support plates of two lower molds. Then, the upper mold is pressed down, so that the lower pressure plate of the upper mold abuts against the flexible shield support and presses it down. During the pressing, the arc-shaped protrusion of the lower pressure plate abuts against the flexible shield support and squeezes it downward. At the contact point of the flexible shield support, it moves downward under force. At this time, the arc-shaped plate rotates outward around the hinge point after being subjected to the pressure transmitted by the flexible shield support. When the arc-shaped plate rotates, it drives the support plate to rotate together. The support plate drives the two side rods of the flexible shield support at the contact point to flip upward until the two side rods of the flexible shield support at the contact point contact the lower pressure plate. Through the above processing fixture, the entire flexible shield support can be bent. Moreover, the bending speed is fast and the operation is convenient. It avoids the traditional method of welding through multiple welding processes, effectively reducing costs and improving production efficiency.

[0012] Preferably, both ends of the support plate extend to the outer side of the arc-shaped plate.

[0013] Preferably, it also includes baffles disposed on both sides of the base plate;

[0014] The bottom outer side of the arc-shaped plate is provided with a limiting part, which is configured such that when the arc-shaped plate rotates outward around the hinge, the limiting part can abut against the baffle.

[0015] Preferably, the upper mold further includes a pressure plate, which is connected to the top of the lower pressure plate.

[0016] Preferably, a second stiffening plate is provided between the lower pressure plate and the bearing plate.

[0017] Preferably, the arc-shaped protrusion has oblique line segments on both sides.

[0018] Preferably, the support includes two parallel vertical plates connected to the base plate;

[0019] The arc-shaped plate is hinged between the two vertical plates.

[0020] Preferably, it further includes a pin that is rotatably mounted on the two upright plates, and the arc-shaped plate is mounted on the pin.

[0021] Preferably, a first stiffening rib is provided between the outer side of the upright plate and the bottom plate.

[0022] This application also discloses a processing system for a flexible shield support, including a flexible shield support and a processing fixture as described in this application, wherein the flexible shield support is horizontally placed on two support plates, and the lower pressure plate abuts against the flexible shield support.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The processing fixture for a flexible shield support described in this application has two uprights on a base plate, spaced apart along the length of the base plate. Each upright is fitted with a lower mold, which includes a support plate and an arc-shaped plate. The support plate is connected to the top of the arc-shaped plate, which is hinged to the upright and can rotate outwards around the hinge. An upper mold is located above the two uprights, and has a lower pressure plate. The lower pressure plate has an arc-shaped protrusion at the center of its bottom surface and is positioned above the area between the two support plates. During the bending process of the flexible shield support, the straight flexible shield support is placed on the support plates of the two lower molds, and then the upper mold is pressed down, causing the lower pressure plate of the upper mold to abut against the flexible shield support. Then, the flexible shield support is pressed down. During the pressing, the arc-shaped protrusion of the pressing plate abuts against the flexible shield support and squeezes it downward. At the point of contact with the flexible shield support, it moves downward under force. At this time, the arc-shaped plate rotates outward around the hinge after being subjected to the pressure transmitted by the flexible shield support. When the arc-shaped plate rotates, it drives the support plate to rotate together. The support plate drives the two side rods at the point of contact of the flexible shield support to flip upward until the two side rods at the point of contact of the flexible shield support come into contact with the pressing plate. Through the above-mentioned processing fixture, the entire flexible shield support can be bent. Moreover, the bending speed is fast and the operation is convenient. It avoids the traditional method of welding through multiple welding processes, effectively reducing costs and improving production efficiency. Attached Figure Description

[0042] Example 1

[0043] like Figures 1-4 As shown, this embodiment discloses a processing fixture for a flexible shield support, comprising:

[0044] Base plate 1;

[0045] Two uprights 2 are spaced apart on the base plate 1 along the length of the base plate 1.

[0046] Two lower molds 3, each mold includes a support plate 31 and an arc plate 32. The support plate 31 is connected to the top of the arc plate 32, and the arc plate 32 is hinged to the stand 2. The arc plate 32 can rotate outward around the hinge.

[0047] The upper mold 4 has a lower pressure plate 41, with an arc-shaped protrusion 411 at the center of the bottom surface of the lower pressure plate 41, and the lower pressure plate 41 is located above the area between the two support plates 31.

[0048] In this embodiment, two uprights 2 are provided on the base plate 1, and the uprights 2 are arranged at intervals along the length of the base plate 1. Each upright 2 is equipped with a lower mold 3, wherein the lower mold 3 includes a support plate 31 and an arc-shaped plate 32. The support plate 31 is connected to the top of the arc-shaped plate 32, and the arc-shaped plate 32 is hinged to the upright 2, and the arc-shaped plate 32 can rotate outward around the hinge point, such as... Figure 1 , Figure 2 ;

[0049] An upper mold 4 is provided above the two uprights 2. The upper mold 4 has a lower pressure plate 41. The lower pressure plate 41 has an arc-shaped protrusion 411 at the center of its bottom surface, and the lower pressure plate 41 is located above the area between the two support plates 31. Figure 4 ;

[0050] like Figure 5 , Figure 6 As shown, during the bending process of the flexible shield support 9, the straight flexible shield support 9 is placed on the support plates 31 of the two lower molds 3, and then the upper mold 4 is pressed down. This causes the lower pressure plate 41 of the upper mold 4 to press down on the flexible shield support 9. During this pressing down, the arc-shaped protrusion 411 of the lower pressure plate 41 abuts against the flexible shield support 9 and presses it downwards. At the point of contact with the flexible shield support 9, it moves downwards under force. At this time, the arc-shaped plate 32 is subjected to the force of the flexible shield support... The pressure transmitted by 9 rotates outward around the hinge. When the arc plate 32 rotates, it drives the support plate 31 to rotate together. The support plate 31 drives the two side rods at the contact point of the flexible shield bracket 9 to flip upward until the two side rods at the contact point of the flexible shield bracket 9 come into contact with the lower pressure plate 41. Through the above-mentioned processing fixture, the entire flexible shield bracket 9 can be bent. The bending speed is fast and the operation is convenient. It avoids the traditional welding method of multiple welding processes, effectively reducing costs and improving production efficiency.

[0051] Furthermore, in this embodiment, the contact point between the flexible shield support 9 and the lower pressure plate 41 is named the bending point 91, such as... Figure 5 , Figure 6 As shown, during the downward pressure, the arc-shaped protrusion 411 of the pressure plate 41 abuts against the bending point 91 of the flexible shield support 9 and presses the flexible shield support 9 downward. When the bending point 91 of the flexible shield support 9 is subjected to force and moves downward, the arc plate 32 rotates outward around the hinge after being subjected to the pressure transmitted by the flexible shield support 9. When the arc plate 32 rotates, it drives the support plate 31 to rotate together. The support plate 31 drives the rods on both sides of the bending point 91 to flip upward until the rods on both sides of the bending point 91 come into contact with the pressure plate 41, thus completing the bending of the flexible shield support 9.

[0052] In optional implementations, such as Figure 3 As shown, the lower mold 3 includes a support plate 31 and an arc plate 32. The support plate 31 is connected to the top of the arc plate 32, and both ends of the support plate 31 extend to the outer side of the arc plate 32.

[0053] The flexible shield support 9 is placed by setting a support plate 31. At the same time, during the bending process of the flexible shield support 9, the support plate 31 can also drive the flexible shield support 9 to rotate upward, thereby speeding up the bending of the flexible shield support 9.

[0054] In optional implementations, such as Figure 3 , Figure 7 As shown, it also includes baffles 5 disposed on both sides of the base plate 1;

[0055] A limiting part 33 is provided on the outer side of the bottom of the arc plate 32. The limiting part 33 is configured such that when the arc plate 32 rotates outward around the hinge, the limiting part 33 can abut against the baffle 5.

[0056] By setting the baffle 5, when the arc plate 32 rotates to a specified angle, the limiting part 33 abuts against the baffle 5, thereby restricting the arc plate 32 from continuing to rotate, and thus ensuring the bending angle of the flexible shield support 9.

[0057] Among them, the baffle 5 is an L-shaped steel plate, which includes a steel vertical plate and a steel bottom plate connected to each other. The steel vertical plate is used to abut against the limiting part 33, and the steel bottom plate is connected to the bottom plate 1.

[0058] Furthermore, multiple threaded holes or strip-shaped threaded grooves are provided at both ends of the base plate, and the steel base plate is threaded into the threaded holes or strip-shaped threaded grooves to achieve a detachable connection between the base plate and the baffle 5, which facilitates the installation and removal of the baffle 5.

[0059] Furthermore, the steel base plate can be positioned on multiple threaded holes or strip-shaped threaded grooves so that the baffle 5 can limit the limiting part 33 at different bending angles.

[0060] In this embodiment, the outer side of the arc plate 32 refers to the side of the arc plate 32 that is away from the other arc plate 32.

[0061] In optional implementations, such as Figure 4 The bottom surface of the lower pressure plate 41 has an arc-shaped protrusion 411 at its center, and the arc-shaped protrusion 411 has oblique line segments 412 on both sides.

[0062] When pressed down, the arc-shaped protrusion 411 of the pressure plate 41 abuts against the bending point 91 of the flexible shield support 9 and presses the flexible shield support 9 downward. When the bending point 91 of the flexible shield support 9 is subjected to force and moves downward, the arc plate 32 rotates outward around the hinge after being subjected to the pressure transmitted by the flexible shield support 9. When the arc plate 32 rotates, it drives the support plate 31 to rotate together. The support plate 31 drives the rods on both sides of the bending point 91 to flip upward until the rods on both sides of the bending point 91 abut against the inclined segment 412 of the pressure plate 41, thus completing the bending of the flexible shield support 9.

[0063] In this application, as Figure 4 As shown, the radius of the arc of the arc-shaped protrusion 411 is R1, the length of the oblique segment 412 is L1, and the length of the side segment 413 is L2. By adjusting the sizes of R1, L1, and L2, multiple pressure plates 41 of different sizes can be made to bend the flexible shield support 9 at different bending angles θ, such as... Figure 9 ;

[0064] like Figure 8 The figure shown is a schematic diagram of a lower pressure plate 41 of another size in this application.

[0065] In optional implementations, such as Figure 1 , Figure 2 As shown, the upper mold 4 also includes a pressure plate 42, which is connected to the top of the lower pressure plate 41.

[0066] An external force is applied to the pressure plate 42 so that the lower pressure plate 41 bends the flexible shield support 9.

[0067] Preferably, the pressure plate 42 is connected to an external hydraulic mechanism, such as the pressure plate 42 being connected to the piston rod of the hydraulic mechanism, so that the pressure plate 42 is pushed downward by the piston rod, thereby bending the flexible shield support 9.

[0068] In optional implementations, such as Figure 2 As shown, a second stiffening plate 8 is provided between the lower pressure plate 41 and the bearing plate 42;

[0069] The second stiffener 8 is spaced apart along the length of the lower pressure plate 41.

[0070] In optional implementations, such as Figure 2 As shown, the support 2 includes two parallel vertical plates 21, which are connected to the base plate 1.

[0071] The curved plate 32 is hinged between the two upright plates 21.

[0072] In an optional embodiment, it also includes a pin 6 rotatably mounted on the two upright plates 21, and an arc-shaped plate 32 mounted on the pin 6;

[0073] Among them, such as Figure 3 As shown, the arc-shaped plate 32 has a first through hole 34, and the pin 6 passes through the first through hole 34 and is installed on the two vertical plates 21.

[0074] In an optional embodiment, a first stiffening plate 7 is provided between the outer side of the upright plate 21 and the bottom plate 1;

[0075] The first stiffening plate 7 is spaced apart along the length of the vertical plate 21.

[0076] Example 2

[0077] like Figures 5-7 As shown, based on Embodiment 1, this embodiment discloses a processing system for a flexible cover support, including a flexible cover support 9 and a processing jig as described in Embodiment 1. The flexible cover support 9 is placed horizontally on two support plates 31, and the lower pressure plate 41 abuts against the flexible cover support 9.

[0078] During the bending process of the flexible shield support 9, the straight flexible shield support 9 is placed on the support plates 31 of the two lower molds 3, and then the upper mold 4 is pressed down. When the lower pressure plate 41 of the upper mold 4 comes into contact with the flexible shield support 9, it presses down on the flexible shield support 9. During the pressing, the arc-shaped protrusion 411 of the lower pressure plate 41 comes into contact with the flexible shield support 9 and squeezes the flexible shield support 9 downward. At the contact point of the flexible shield support 9, it moves downward under force. At this time, the arc plate 32 rotates outward around the hinge after being subjected to the pressure transmitted by the flexible shield support 9. When the arc plate 32 rotates, it drives the support plate 31 to rotate together. The support plate 31 drives the rods on both sides of the contact point of the flexible shield support 9 to flip upward until the rods on both sides of the bending point 91 come into contact with the lower pressure plate 41. The bending speed is fast and the operation is convenient. It avoids the traditional welding method of multiple welding processes, effectively reducing costs and improving production efficiency.

[0079] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
