Description

Technical Field

[0001] This invention relates to the field of double-row chain scraper technology, and more specifically to a double-row chain scraper straightening device for scraper machines. Background Technology

[0002] In the transportation of materials in copper smelting, scraper conveyors are frequently used. Due to material caking or the entry of foreign objects, scrapers are easily bent and deformed. Too many bent scrapers can cause scraper chain slippage, affecting the operation of the scraper conveyor. Currently, the main maintenance methods are to disassemble the scrapers and replace them with new ones, or to heat them at high temperatures and then straighten them by hitting them with a sledgehammer. The scraper replacement method takes a long time and is not feasible under production conditions. Although high-temperature heating straightening is faster and can be started up at any time, the straightening effect is poor, the labor intensity is high, and the sledgehammer straightening process can easily cause some damage to the scrapers, affecting their service life.

[0003] Therefore, based on this, a design or technical improvement is proposed to solve the above-mentioned problems.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a double-row chain scraper straightening device for scraper conveyors.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A scraper conveyor double-row chain scraper straightening device, comprising:

[0008] Base;

[0009] A clamping mechanism is mounted on the base and is used to clamp the scraper. The clamping mechanism is provided with two sets of clamping parts that can be limited and slidably.

[0010] A hydraulic rod, mounted on the base, is used to correct the bending of the scraper.

[0011] A limiting mechanism is installed on the clamping mechanism to limit the clamping part of the clamping mechanism.

[0012] Furthermore, the clamping mechanism includes a sliding buckle plate that slides on the upper limit of the base, a clamping arm disposed on the sliding buckle plate, and a fastening bolt that passes through the sliding buckle plate and movably engages with a first movable slot opened on the base.

[0013] Furthermore, the clamping arm includes a main clamping arm disposed on the sliding plate, a secondary clamping arm that slides at the upper limit of the main clamping arm, and an adjusting screw that is connected to the bearing of the main clamping arm and threadedly connected to the secondary clamping arm. The clamping part is disposed at the opposite ends of the main clamping arm and the secondary clamping arm. The main clamping arm and the secondary clamping arm are inserted and limited by a limiting slide rail disposed on the main clamping arm and a limiting slider disposed on the secondary clamping arm.

[0014] Furthermore, the clamping part includes a wear-resistant liner and a limiting block disposed on the wear-resistant liner. The wear-resistant liner is slidably engaged with the limiting slots opened on the main clamping arm and the auxiliary clamping arm respectively through the limiting block.

[0015] Furthermore, the limiting mechanism includes a buckle assembly for sliding and limiting the wear-resistant liner, an elastic assembly disposed on the wear-resistant liner for controlling the sliding reset of the wear-resistant liner, and an opening assembly disposed at the end of the hydraulic rod for controlling the buckle assembly to disengage from the wear-resistant liner.

[0016] Furthermore, the buckle assembly includes a limiting rail plate that is vertically and vertically limited on the main clamping arm and movably connected to a second movable groove on the auxiliary clamping arm, and a locking pin that is vertically slidable on the limiting rail plate and movably connected to an insertion groove on the wear-resistant liner.

[0017] Furthermore, the elastic component includes a connecting plate disposed between the wear-resistant liners, a limiting rod disposed on the connecting plate and movably connected to the wear-resistant liners, and a first spring disposed at one end on the connecting plate and at the other end on the wear-resistant liners and sleeved with the limiting rod.

[0018] Furthermore, the buckle-opening assembly includes a movable plate frame disposed at the end of the hydraulic rod and a buckle-opening bracket disposed on the movable plate frame.

[0019] Furthermore, the movable plate frame includes a rear push plate connected to a hydraulic rod, a front push plate connected to a limiting slide rod that movably passes through the rear push plate, and a second spring with one end set on the rear push plate and the other end set on the front push plate.

[0020] Furthermore, the buckle opening frame includes a push arm disposed on the rear push plate, a support frame disposed on the front push plate, and a linkage frame disposed between the limit rail plates.

[0021] The linkage frame includes a connecting rod mounted on the limiting rail plate, a connecting sleeve plate whose two ends are movably sleeved with the connecting rod, and a cross frame abutment plate mounted on the connecting sleeve plate.

[0022] The support frame includes a movable push block that is limited to move within a third movable groove opened on the front push plate, and a third spring with one end set on the third movable groove and the other end set on the movable push block. The movable push block and the push arm are wedge-shaped abutted together, and the movable push block and the cross frame abutment are movably abutted together.

[0023] Compared with existing technologies, the advantages of this solution are: the device designed in this solution is smaller in size and simpler to operate, and the scraper can be corrected directly on the equipment without disassembling the scraper.

[0024] The two clamping mechanisms on the device can clamp the two ends of the deformed part of the scraper, avoiding damage to the workpiece caused by uneven force during the correction process.

[0025] The movable structure between the clamping components and the base allows the device to clamp and correct scrapers of different lengths. The sliding structure between the main clamping arm and the auxiliary clamping arm allows the device to adjust the distance between the two clamping components according to the length of the workpiece to be corrected. Both sets of structures are equipped with locking mechanisms, so that the device can adapt to workpieces of different specifications without losing stability. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1-8 The scraper straightening device for a double-row chain scraper conveyor shown includes a base 1; a clamping mechanism, mounted on the base 1, for clamping a scraper 11, the clamping mechanism having two sets of clamping parts that can be limited and slidably positioned; a hydraulic rod 13, mounted on the base 1, for straightening the bent portion of the scraper 11; and a limiting mechanism, mounted on the clamping mechanism, for limiting the clamping portion of the clamping mechanism. The device is compact in size and can be directly straightened on the machine without disassembling the scraper 11. Specifically, the straightening method involves clamping both ends of the scraper 11 with the clamping mechanism, aligning the bent protruding part with the end of the hydraulic rod 13, thereby driving the hydraulic rod 13 to work, thus supporting the protruding part of the scraper 11 and restoring it to a flat state.

[0038] In one embodiment, the clamping mechanism includes a sliding plate 2 that slides on the upper limit of the base 1, a clamping arm disposed on the sliding plate 2, and a fastening bolt 21 that passes through the sliding plate 2 and movably passes through the first movable groove 12 opened on the base 1. When the device needs to adjust the clamping distance at both ends according to the length of the scraper 11, the sliding plate 2 slides on the base 1, causing the fastening bolt 21 to slide inside the first movable groove 12, thereby allowing the clamping mechanism to clamp both ends of the scraper 11 at a suitable position, and then locking the sliding plate 2 with the fastening bolt 21 to maintain the stability of the clamping structure.

[0039] In one embodiment, the clamping arm includes a main clamping arm 22 disposed on the sliding plate 2, a secondary clamping arm 23 that slides at the upper limit of the main clamping arm 22, and an adjusting screw 24 that is bearing-connected to the main clamping arm 22 and threadedly connected to the secondary clamping arm 23. The clamping part is disposed at the opposite ends of the main clamping arm 22 and the secondary clamping arm 23. The main clamping arm 22 and the secondary clamping arm 23 are inserted and limited by a limiting slide rail 25 disposed on the main clamping arm 22 and a limiting slider 26 disposed on the secondary clamping arm 23. When the main clamping arm 22 and the secondary clamping arm 23 clamp the scraper 11, the adjusting screw 24 is first rotated to open the main clamping arm 22 and the secondary clamping arm 23 relative to each other, thereby placing the main clamping arm 22 and the secondary clamping arm 23 on both sides of the scraper 11. Then, the adjusting screw 24 is rotated to move the secondary clamping arm 23 closer to the main clamping arm 22, thereby clamping and fixing the scraper 11, and then the correction work is performed.

[0040] In one embodiment, the clamping part includes a wear-resistant liner 27 and a limiting block 28 disposed on the wear-resistant liner 27. The wear-resistant liner 27 is slidably engaged with the limiting slots 29 opened on the main clamping arm 22 and the auxiliary clamping arm 23 respectively through the limiting block 28. When the scraper 11 is being straightened, the scraper 11 will extend to both sides as it gradually straightens from a bent state. As a result, the wear-resistant liner 27 that needs to hold the scraper 11 will move to both sides along with the scraper 11. Thus, a transverse limiting movable connection structure is set between the wear-resistant liner 27 and the main clamping arm 22 and the auxiliary clamping arm 23, so as to facilitate its extension movement with the scraper 11.

[0041] In one embodiment, the limiting mechanism includes a latching assembly for sliding and limiting the wear-resistant liner 27, an elastic assembly disposed on the wear-resistant liner 27 for controlling the sliding reset of the wear-resistant liner 27, and an opening assembly disposed at the end of the hydraulic rod 13 for controlling the latching assembly to disengage from the wear-resistant liner 27. The latching assembly includes a limiting rail plate 31 that is vertically and vertically limited on the main clamping arm 22 and movably connected to the second movable groove 3 opened on the auxiliary clamping arm 23, and an insertion joint that is limited and slids on the limiting rail plate 31 and is opened on the wear-resistant liner 27. The slot 32 is movably connected to the insertion pin 33. The elastic component includes a connecting plate 4 disposed between the wear-resistant liners 27, a limiting rod 41 disposed on the connecting plate 4 and movably connected to the wear-resistant liner 27, and a first spring 42 disposed at one end on the connecting plate 4 and at the other end on the wear-resistant liner 27 and sleeved with the limiting rod 41. The buckling component includes a movable plate frame disposed at the end of the hydraulic rod 13 and a buckling bracket disposed on the movable plate frame. When the clamping mechanism needs to clamp the scraper 11 at both ends, it is necessary to prioritize the clamping mechanism according to the scraper 11. The length of the clamping mechanism is adjusted to allow it to clamp at appropriate positions at both ends of the scraper 11. Priority is given to controlling the movement of the clamping mechanism. The wear-resistant liner 27 is arranged in a laterally relative movable structure with the main clamping arm 22 and the auxiliary clamping arm 23. To ensure that the wear-resistant liner 27 moves synchronously with the main clamping arm 22 and the auxiliary clamping arm 23, a limiting mechanism is installed at its upper end. When the latching components on the main clamping arm 22 and the auxiliary clamping arm 23 in the limiting mechanism are engaged with the wear-resistant liner 27, the wear-resistant liner 27 is secured to the main clamping arm 22. The main clamping arm 22 and the auxiliary clamping arm 23 are pinned together, which enables them to maintain synchronous operation. When the clamping mechanism is clamped on the scraper 11 and stabilized, the process of correcting the scraper 11 will drive the buckle opening component to work, thereby causing the buckle component to separate from the wear-resistant liner 27. This allows the wear-resistant liner 27 to move relative to the main clamping arm 22 and the auxiliary clamping arm 23, so that the wear-resistant liner 27 can extend and slide synchronously with the scraper 11 being corrected during the process of stabilizing the two ends of the scraper 11.

[0042] In one embodiment, the movable plate frame includes a rear push plate 5 connected to a hydraulic rod 13, a front push plate 52 connected to a limiting slide rod 51 that is movably connected to the rear push plate 5, and a second spring 53 with one end on the rear push plate 5 and the other end on the front push plate 52. The second spring 53 allows the rear push plate 5 and the limiting slide rod 51 to maintain elastic movement, thereby allowing them to change and reset their relative distance under the support of the hydraulic rod 13, and thus control the movement of the buckle opening frame by changing the relative distance between them.

[0043] In one embodiment, the buckle opening frame includes a push arm 54 disposed on the rear push plate 5, a support frame disposed on the front push plate 52, and a linkage frame disposed between the limiting rail plates 31; the linkage frame includes a connecting rod 56 disposed on the limiting rail plate 31, a connecting sleeve plate 57 whose two ends are movably sleeved with the connecting rod 56, and a cross frame abutment plate 58 disposed on the connecting sleeve plate 57; the support frame includes a movable push block 59 that is limited and movable within a third movable groove 55 opened on the front push plate 52, and a first... The three springs 510, the movable push block 59 and the push arm 54 are wedge-shaped and abut each other. The movable push block 59 and the cross frame abutment plate 58 are movable and abut each other. The movable push block 59 can be moved upward by the push arm 54 abutting the movable push block 59. In turn, the movable push block 59 will push the cross frame abutment plate 58 to move upward, thereby driving the connecting rod 56 inside the connecting sleeve plate 57 to move upward. This will then link and control the limiting rail plate 31 connected to the other end of the connecting rod 56, so that the insert pin 33 inside the limiting rail plate 31 slides upward, causing the insert pin 33 to disengage from the wear-resistant liner plate 27.

[0044] The specific working method of this device is as follows: First, adjust the relative distance between the two sets of main clamping arms 22 according to the length of the scraper 11, so that they correspond to appropriate positions at both ends of the curved part of the scraper 11. After the adjustment is completed, tighten the fastening bolts 21 to lock the position of the main clamping arms 22. Then, by rotating the adjusting screw 24, the relative distance between the main clamping arms 22 and the auxiliary clamping arms 23 is increased. Then, place both ends of the curved part of the scraper 11 between the wear-resistant liners 27, and then rotate the adjusting screw 24 to clamp and fix the scraper 11 with the wear-resistant liners 27. Then, drive the hydraulic rod 13 to extend, and its front end will push the rear push plate 5 and the front push plate 52 forward. After the front push plate 52 abuts against the protruding part of the scraper 11, the front push plate 52 will remain temporarily stationary, and the rear push plate 5 will continue to move forward, so that the upper push arm 54 abuts against the movable push block 59, thereby pushing the movable push block 59 to move upward, thereby pushing the upper horizontal... The upward movement of the frame abutment plate 58, via the connecting sleeve plate 57, causes the internal sliding connecting rod 56 to move upward, which in turn causes the insertion pin 33 to move upward via the limiting rail plate 31. This disengages the insertion pin 33 from the insertion groove 32 on the wear-resistant liner plate 27, allowing the wear-resistant liner plate 27 to slide relative to the main clamping arm 22 and the auxiliary clamping arm 23. At this point, the rear push plate 5 and the front push plate 52 are already abutted and secured. Furthermore, under the continued extension of the hydraulic rod 13, the... The rear push plate 5 and the front push plate 52 together apply a pushing force to the protrusion of the scraper 11, so that the protrusion is gradually flattened. During the flattening process, the two ends of the scraper 11 will extend to both sides. At this time, since the wear-resistant liner 27 is movable relative to the main clamping arm 22 and the auxiliary clamping arm 23, the wear-resistant liner 27 can be driven to slide to both sides gradually during the extension of the scraper 11 until the concave surface of the protrusion of the scraper 11 is in contact with the connecting plate 4 on its corresponding side, then the correction is completely implemented.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
