Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel plate processing technology, specifically a fall-prevention clamp for steel plate hoisting. Background Technology
[0002] On a modern steel plate processing production line, the clamping, fixing, hoisting, and transportation of the plates are the core links that affect the overall production efficiency and operational safety.
[0003] Currently, mechanical clamping devices are commonly used in the industry. Their typical structure includes hydraulic / pneumatic clamping mechanisms, which achieve fixation by contacting the steel plate surface with a rigid clamping surface.
[0004] However, this technical solution still has the following shortcomings:
[0005] When traditional clamping mechanisms switch horizontal postures, the direction of the clamping force changes vectorwise with the direction of gravity. Clamping methods that rely solely on friction are prone to relative slippage of the steel plate, leading to a critical risk of instability under acceleration conditions.
[0006] Current equipment mostly adopts a single-degree-of-freedom linear lifting mode, and its movement trajectory is limited by a fixed guide rail system. When multi-angle alignment is required, it is necessary to rely on the overall movement of the overhead crane system, resulting in insufficient positioning accuracy and time-consuming adjustments that take up part of the work cycle. Utility Model Content
[0007] The purpose of this utility model is to provide a fall-prevention clamp for steel plate hoisting, so as to solve the problems mentioned in the prior art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a steel plate hoisting anti-fall clamp, comprising: a main plate, guide cavities disposed on both sides of the main plate, a secondary plate slidably extending out of the guide cavities, a mounting chamber disposed within the main plate, a drive unit connected to the mounting chamber and drivingly connected to the secondary plate, two sets of clamping units disposed on the outer side of the secondary plate, an electromagnet fixedly connected to the bottom of the main plate, a support component fixedly connected to the top of the main plate, and a reversing unit connected to the top of the support component; a clamping unit, a clamping arm connected to the mounting opening, and fixedly mounted on... The clamping arm has a guide arm at the top, a hydraulic telescopic cylinder fixed to the top of the sub-plate and movably hinged to the guide arm, and a clamping plate at the bottom of the clamping arm; a reversing unit has a hydraulic rotary cylinder connected to the top of the support component, a lower seat fixed to the top of the hydraulic rotary cylinder, a movable shaft two connected to the lower seat, an upper seat connected to the movable shaft two, and a worm gear reducer fixed to one side of the upper seat; a drive unit has a threaded rod connected to the guide cavity and extending into the sub-plate, and a geared motor fixed to the support component and driven by the threaded rod.
[0009] As a preferred embodiment, the output end of the hydraulic telescopic cylinder is fitted with a mounting base, and a guide post that penetrates the guide arm is fitted inside the mounting base. A movable shaft that is movably connected to the sub-plate is fitted on the clamping arm, and a rubber pad is fixedly fitted on the top of the clamping plate.
[0010] As a preferred embodiment, a mounting plate is fixedly installed on the top of the upper body, and the top of the mounting plate is provided with a mounting hole, and a through interface is provided on the mounting hole.
[0011] As a preferred embodiment, a support base is fixedly mounted on the top of the motherboard, an output shaft is fixedly mounted on the top of the support base, a geared motor is installed inside the support frame, and a hydraulic rotary cylinder is installed on the top of the support frame.
[0012] As a preferred embodiment, the output end of the geared motor is connected to an output shaft extending into the installation chamber, a main gear is fixedly mounted on the output shaft, one end of the threaded rod is connected to a transmission shaft extending into the installation chamber, and a secondary gear that meshes with the main gear is fixedly mounted at the end of the transmission shaft.
[0013] As a preferred feature, the front and back sides of the sub-plate are fixedly provided with slide rails, and the slide rails are slidably connected to the main plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By cooperating with the clamping unit and the electromagnet, the device can combine extraction and clamping. This not only avoids the situation where the device cannot extract quickly due to the stacking of plates, but also ensures that the plates do not fall during extraction and lowering. By switching between the two, the clamping of the plates is made more convenient and stable.
[0016] The reversing unit allows the device to switch the direction of the clamped plates according to actual operational needs, enabling effective adjustment of the placement surface of the clamped plates. This allows the device to not only pick up and place plates longitudinally but also laterally, improving the adaptability of the device during operation, ensuring flexibility during adjustment, and shortening the adjustment cycle.

[0031] 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.
[0032] Example: This utility model provides a technical solution for a fall arrestor for steel plate hoisting, such as... Figures 1-6As shown, it includes: a main board 100, guide cavities 1001 disposed on both sides of the main board 100, a sub-plate 200 slidably extending out of the guide cavities 1001, a mounting chamber 1002 disposed in the main board 100, a drive unit 600 connected to the mounting chamber 1002 and drivingly connected to the sub-plate 200, two sets of clamping units 300 disposed on the outside of the sub-plate 200, an electromagnet 700 fixed to the bottom of the main board 100, a support member 500 fixed to the top of the main board 100, and a reversing unit 400 connected to the top of the support member 500.
[0033] In the above scheme:
[0034] Through the cooperation between the main board 100 and the sub-board 200, the drive unit 600 can effectively promote its linear expansion, so that the fixture can be adjusted in real time according to the actual size of the clamped plate, thereby improving the adaptability of the fixture during operation.
[0035] By cooperating with the clamping unit 300 and the electromagnet 700, the device can combine extraction and clamping. This not only avoids the situation where the device cannot extract quickly due to the stacking of plates, but also ensures that the plates do not fall during extraction and lowering. By switching between the two, the plates are more convenient and stable when clamped.
[0036] The reversing unit 400 enables the device to switch the direction of the clamped plates according to actual operational needs, thereby effectively adjusting the placement surface of the clamped plates. This allows the device to not only pick up and place plates longitudinally but also laterally, improving the adaptability of the device during operation.
[0037] The clamping unit 300 includes a clamping arm 306 docked in the mounting port 201, a guide arm 303 fixed to the top of the clamping arm 306, a hydraulic telescopic cylinder 301 fixed to the top of the sub-plate 200 and movably hinged to the guide arm 303, and a clamping plate 307 docked at the bottom of the clamping arm 306.
[0038] The reversing unit 400 includes a hydraulic rotary cylinder 401 docked to the top of the support component 500, a lower seat 405 fixed to the top of the hydraulic rotary cylinder 401, a second movable shaft 404 docked to the lower seat 405, an upper seat 403 docked to the second movable shaft 404, and a worm gear reducer 402 fixed to one side of the upper seat 403.
[0039] The drive unit 600 includes a threaded rod 605 that is mated in the guide cavity 1001 and extends into the sub-plate 200, and a geared motor 601 that is fixed in the support member 500 and is drively connected to the threaded rod 605.
[0040] During daily operations:
[0041] When the plate is first extracted, the electromagnet 700 is activated to attract the outer surface of the plate and extract it to a certain height. Then, the geared motor 601 is activated to drive the threaded rod 605. The threaded rod 605 drives the sub-plate 200, causing the sub-plate 200 to extend outward within the main plate 100. This causes the clamping distance to be adjusted to the required size of the plate and ensures that the clamping plate 307 is positioned on both sides of the plate. Then, the compression telescopic cylinder 301 is activated to drive the guide arm 303 at the end, which in turn drives the clamping arm 306 at the bottom. The clamping arm 306 drives the clamping plate 307 at the bottom to retract inward, and the clamping plate 307 completes the bottom clamping and fixing of the plate.
[0042] At this point, the device can be used with the lifting equipment for transfer. During the transfer, if the plate needs to be placed vertically, the motor on the worm gear reducer 402 is started to drive the clamped plate to switch to the vertical position. When in the vertical position, it is necessary to ensure that the electromagnet 700 is in the starting position to increase the risk of falling. If the angle needs to be switched, the hydraulic rotary cylinder 401 can be started to drive the components below to rotate and adjust, switching the direction of plate placement or extraction.
[0043] like Figures 1-6 As shown, in order to enable the hydraulic telescopic cylinder 301 to drive the guide arm 303, the output end of the hydraulic telescopic cylinder 301 is further connected to the mounting base 302, and the mounting base 302 is connected to the guide post 304 that passes through the guide arm 303. The clamping arm 306 is connected to the movable shaft 305 that is movably connected to the sub-plate 200, and the top of the clamping plate 307 is fixedly installed with a rubber pad 308.
[0044] Specifically, when the hydraulic telescopic cylinder 301 is activated, the mounting base 302 at the end of the hydraulic telescopic cylinder 301 can drive the guide post 304 inside the mounting base 302 to drive the guide arm 303. The guide arm 303 is provided with a guide opening through which the guide post 304 passes, thus driving the clamping arm 306. At that time, the clamping arm 306 can swing within the sub-plate 200 via the movable shaft 305 to drive the clamping plate 307. The clamping plate 307 uses its own rubber pad 308 to clamp the bottom of the plate.
[0045] like Figure 3 As shown, in order to facilitate the assembly and connection between the device and the lifting device, a mounting plate 406 is further fixedly installed on the top of the upper body 403, and a mounting hole 4062 is provided on the top of the mounting plate 406, with a through interface 4061 provided on the mounting hole 4062.
[0046] Specifically, the mounting plate 406 connects with the lifting point of the lifting device via the top interface 4061. After ensuring the complete connection of the interface 4061, the mounting plate 406 and the lifting point can be fastened together using parts to complete the assembly.
[0047] Furthermore, a support base 501 is fixedly installed on the top of the main board 100, an output shaft 602 is installed on the top of the support base 501, a reduction motor 601 is installed inside the support frame 502, and a hydraulic rotary cylinder 401 is installed on the top of the support frame 502.
[0048] Specifically, the support base 501 is a connecting part that supports and fixes the upper components, while the support frame 502 can effectively provide installation space for the geared motor 601;
[0049] During operation, the output end of the geared motor 601 can drive the output shaft 602 to rotate, thereby driving the bottom component.
[0050] In order for the geared motor 601 to complete the driving operation of the auxiliary plate 200, the output end of the geared motor 601 is connected to an output shaft 602 extending into the mounting chamber 1002. A main gear 603 is fixedly installed on the output shaft 602. One end of the threaded rod 605 is connected to a transmission shaft 604 extending into the mounting chamber 1002, and a secondary gear 606 that meshes with the main gear 603 is fixedly installed at the end of the transmission shaft 604.
[0051] Specifically, in conjunction with the above, during operation, the output end of the geared motor 601 can drive the output shaft 602 to rotate, thereby driving the bottom main gear 603. The main gear 603 then links with the auxiliary gear 606. At that time, the auxiliary gear 606, in conjunction with the transmission shaft 604, synchronously drives the threaded rod 605, causing the threaded rod 605 to drive the auxiliary plate 200, enabling the auxiliary plate 200 to extend and retract outward.
[0052] The front and back sides of the sub-board 200 are fixedly provided with slide rails 202, and the slide rails 202 are slidably connected to the main board 100.
[0053] When the sub-plate 200 extends or retracts outward, the sub-plate 200 uses its own sliding plate 202 to ensure stable transmission.
[0054] The hydraulic cylinders, motors, and reducers mentioned above are all commonly used working devices in the field today, and will not be elaborated on further here.
[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this 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 this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
