Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to a hoisting device for component production. Background Technology

[0002] Lifting slings are core equipment in lifting operations. As rigid lifting devices, they are primarily used in conjunction with rigging to achieve stable material handling. They are crucial in various industrial lifting scenarios, ensuring both efficiency and safety during the lifting process.

[0003] Currently, in the production process of hollow fiber flat sheet membranes, lifting tools are widely used for the handling and installation of membrane modules to meet the needs of precision and large-scale production.

[0004] The prior art disclosure number CN222361819U discloses a hoisting device for the production of hollow fiber flat sheet membrane modules, which includes a top hanging plate. The bottom of the top hanging plate has a number of evenly distributed movable openings. A positioning clamp is fixedly installed on the right side wall of each movable opening, and a sliding clamp is slidably installed in each movable opening.

[0005] When hollow fiber flat sheet membrane modules are finally installed into the MBR membrane box, they need to be arranged with non-equidistant spacing according to the process design requirements (e.g., the spacing between membrane modules near the aeration pipes is larger, and the spacing in the central area is smaller). The fixed spacing clamping mode of the hoisting device does not match the actual variable spacing installation requirements, which means that the membrane modules must be manually adjusted again after hoisting. This not only affects the installation efficiency, but may also cause damage to the membrane fibers due to repeated handling.

[0006] Therefore, improvements are proposed. Utility Model Content

[0007] This utility model is a hoisting device for component production proposed to overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a hoisting device for component production, including a top hoisting plate, wherein a plurality of slots are uniformly formed on the outer surface of the top hoisting plate;

[0009] An electric spline shaft is fixedly installed at one end of the top hanging plate;

[0010] The bottom of the outer surface of the ceiling plate is slidably fitted with multiple mounting seats, and each of the mounting seats has an elastic retaining plate installed on one side of its outer surface, and the elastic retaining plate matches the retaining groove.

[0011] Each of the mounting bases has an adjusting screw extending through to the other side on one side of its outer surface, and the adjusting screw is slidably sleeved on the shaft of the electric spline shaft;

[0012] Each of the multiple adjusting screws has a pressure plate threaded onto its outer surface, and each of the multiple mounting seats has a positioning seat detachably fixed on one side of its outer surface. Each of the multiple positioning seats has a flat membrane assembly positioned and sleeved onto its outer surface.

[0013] Furthermore, the electric spline shaft includes a motor, which is fixedly installed at one end of the top plate. The drive end of the motor is fixedly connected to the spline shaft body, which can synchronously drive multiple adjusting screws to rotate.

[0014] Furthermore, each of the mounting bases has an assembly groove at its bottom, and the pressure plate slides against the inner walls on both sides of the assembly groove. The assembly groove has a limiting effect on the pressure plate, which can ensure the stability of the pressure plate's movement.

[0015] Furthermore, each of the multiple elastic plates includes an L-shaped plate, which extends through the mounting base and is slidably connected to it. The L-shaped plate matches the slot, and a tension spring is fixedly connected between the L-shaped plate and the mounting base. The tension spring facilitates the repositioning of the L-shaped plate.

[0016] Furthermore, the adjusting screw includes a screw body, which completely penetrates the mounting base and is rotatably connected to it. The pressure plate is threaded onto the outer surface of the screw body. One end of the screw body has a spline hole that extends to the other end, and the spline hole matches the spline shaft body. The spline hole facilitates the screw body being fitted onto the spline shaft body.

[0017] Furthermore, each of the multiple positioning seats includes a mounting plate, and the mounting plate is attached to one side of the outer surface of the mounting seat. The mounting plate and the mounting seat are fixedly connected by two bolts. A positioning block is fixedly connected to one side of the outer surface of the mounting plate, and the flat film assembly is positioned and sleeved on the outer surface of the positioning block.

[0018] The beneficial effects of this utility model are:

[0019] In use, this utility model provides a lifting device for component production. The improved lifting device achieves flexible adjustment of the membrane module spacing through the cooperation of slots, mounting seats, and elastic clamping plates. The elastic clamping plates can quickly engage or disengage from the slots, allowing the mounting seats to slide along the top hanging plate to the desired position. Simultaneously, an electric spline shaft drives the adjusting screw to rotate synchronously, causing the pressure plate to tighten or loosen the flat membrane module, achieving rapid locking after adjustment. This design solves the problem of traditional lifting devices requiring secondary adjustment of membrane modules due to fixed spacing. It not only meets the installation requirements of non-equidistant MBR membrane boxes but also completes positioning and locking in one go, avoiding damage to the membrane fibers caused by repeated handling, and significantly improving installation efficiency.

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5 As shown, a hoisting device for component production is disclosed, including a top hoisting plate 1, with a plurality of slots 5 evenly distributed on the outer surface of the top hoisting plate 1.

[0030] An electric spline shaft is fixedly installed at one end of the ceiling plate 1. The electric spline shaft includes a motor 3, and the motor 3 is fixedly installed at one end of the ceiling plate 1. The drive end of the motor 3 is fixedly connected to the spline shaft body 8. The motor 3 is a servo or stepper motor, which can precisely control the speed of the spline shaft body 8 and ensure the stability of the adjusting screw when rotating synchronously.

[0031] Multiple mounting bases 4 are slidably sleeved on the bottom of the outer surface of the ceiling plate 1. Each mounting base 4 has an elastic plate installed on one side of its outer surface, and the elastic plate matches the slot 5. Each elastic plate includes an L-shaped plate 6, which passes through the mounting base 4 and is slidably connected to the mounting base 4. The L-shaped plate 6 matches the slot 5, and a tension spring 11 is fixedly connected between the L-shaped plate 6 and the mounting base 4.

[0032] Each of the multiple mounting bases 4 has an adjusting screw extending through to the other side on one side of its outer surface. The adjusting screw is slidably sleeved on the shaft of the electric spline shaft. The adjusting screw includes a screw body 13, which completely penetrates the mounting base 4 and is rotatably connected to the mounting base 4. The pressure plate 9 is threaded onto the outer surface of the screw body 13. One end of the screw body 13 has a spline hole 12 extending through to the other end, and the spline hole 12 matches the spline shaft body 8.

[0033] Multiple adjusting screws have pressure plates 9 threaded onto their outer surfaces. Multiple mounting bases 4 have assembly grooves 15 at their bottoms. The pressure plates 9 slide against the inner walls of the two sides of the assembly grooves 15. The inner walls of the assembly grooves 15 can be fitted with a wear-resistant coating or a guide rail structure to reduce the frictional resistance when the pressure plates 9 slide, ensuring a smooth locking process and enhancing long-term durability. A positioning seat can be detachably fixed on one side of the outer surface of multiple mounting bases 4. A flat diaphragm assembly 2 is positioned and sleeved on the outer surface of multiple positioning seats.

[0034] Multiple positioning seats include mounting plates 7, and the mounting plates 7 are attached to one side of the outer surface of the mounting seat 4. The mounting plates 7 and the mounting seats 4 are fixedly connected by two bolts 14. A positioning block 10 is fixedly connected to one side of the outer surface of the mounting plate 7, and the flat membrane module 2 is positioned and sleeved on the outer surface of the positioning block 10. The positioning block 10 can be covered with an elastic material (such as rubber or silicone) to avoid damage caused by rigid contact during membrane module installation, and at the same time enhance the anti-slip fixing effect.

[0035] Spacing adjustment stage:

[0036] The operator first pulls the L-shaped plate 6 on the mounting base 4 outward to disengage it from the slot 5 on the ceiling plate 1. At this time, the mounting base 4 can slide freely along the ceiling plate 1.

[0037] According to the process requirements of the MBR membrane box (such as larger spacing near the aeration pipes and smaller spacing in the central area), the positions of each mounting base 4 are manually adjusted so that the flat sheet membrane modules 2 are distributed with non-equidistant spacing.

[0038] After adjustment, release the L-shaped plate 6, and the tension spring 11 will drive it to automatically rebound, so that the L-shaped plate 6 can be inserted into the corresponding slot 5, thus positioning the mounting base 4.

[0039] Synchronous locking phase:

[0040] Start motor 3 to drive spline shaft body 8 to rotate. Since each screw body 13 is linked to spline shaft body 8 through spline hole 12, all screw bodies 13 rotate synchronously.

[0041] When the screw body 13 rotates, the threaded pressure plate 9 moves along the assembly groove 15, pressing the flat diaphragm group 2 to fix it firmly on the positioning seat.

[0042] Because the electric spline shaft drives all adjusting screws to move synchronously, the locking force of each membrane assembly is consistent, avoiding deformation or loosening caused by uneven force at a single point.

[0043] Overall hoisting stage:

[0044] After the spacing adjustment and locking are completed, the membrane module is hoisted as a whole through the top hanging plate 1 and installed directly into the MBR membrane box according to the preset spacing without the need for secondary adjustment.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
