Description

Technical Field

[0001] This utility model provides an auxiliary support for the construction of industrial silicon ingot molds, belonging to the technical field, and specifically relating to an auxiliary support for the construction of industrial silicon ingot molds. Background Technology

[0002] Industrial silicon ingot mold construction refers to the process in industrial production of using specific bricks and materials, and constructing molds according to certain structures and dimensions to manufacture silicon ingots. These molds have specific shapes and properties to meet the process requirements of silicon ingot production.

[0003] Existing industrial silicon ingot mold construction devices mostly adopt fixed welded steel frame structures, typically consisting of two upright steel columns welded to a top crossbeam to form an integral frame. The bottom is fixed to the ground by simple steel plates welded together. Only a few fixing holes are set on the columns for adjusting the height of the crossbeam, and the adjustment requires disassembling the bolts and then re-welding or drilling holes for fixation. This traditional structure has significant shortcomings: First, the crossbeam height adjustment has low accuracy and takes a long time, which cannot adapt to the needs of rapid changes in the size of silicon ingot molds; Second, it lacks a multi-angle, multi-dimensional linkage locking mechanism between the fan-shaped adjustment plate and the sleeve clamping parts, resulting in poor crossbeam stability, with deflection exceeding 5mm under a load of 300kg. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides an auxiliary support for the construction of industrial silicon ingot molds, which solves the problems of low efficiency and poor stability in adjusting the height of the crossbeam.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an auxiliary support for the construction of industrial silicon ingot molds, including a left column and a right column;

[0006] Both the left and right columns are vertically arranged elongated plate-like structures with multiple holes evenly distributed along their length for connection and fixation; the left and right columns are respectively equipped with crossbeams and connectors.

[0007] The crossbeam is a horizontally arranged long strip-shaped rod structure, with its two ends connected to the upper parts of the left and right columns respectively through connectors. The connectors can move along the length of the left and right columns and be fixed in holes at different positions to adjust the height of the crossbeam.

[0008] The connector is a U-shaped plate with its opening facing downwards, and several fan-shaped adjustment plates are fixedly connected to the connector.

[0009] Preferably, both the left and right columns are provided with a base below them. The base is a horizontally arranged elongated plate structure used to support the entire bracket and maintain its stability.

[0010] Preferably, the connector has mounting holes that correspond to and penetrate the hole, and the adjustment plate has several evenly distributed adjustment holes.

[0011] Preferably, the adjusting plate is externally clamped with a corresponding clamping component. The clamping component on the left column is mechanically connected to the crossbeam; the clamping component on the right column has an integrally connected sleeve on the side near the crossbeam, the sleeve is fitted onto the crossbeam and can move along the length of the crossbeam.

[0012] Preferably, the clamping member has a through hole that passes through itself and corresponds to the adjustment hole, and the clamping member and the adjustment plate are connected by a locking bolt structure that passes through the through hole and corresponds to the adjustment hole.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] This device achieves stepless and rapid adjustment of the beam height through the sliding cooperation of densely distributed holes on the left and right columns and U-shaped connectors. Combined with the multi-angle locking structure of the fan-shaped adjustment plate fixed at the bottom of the connector, when the beam is loaded with 300kg, the stress dispersion of the fan-shaped plate reduces the deflection to ≤2mm, thus solving the dual defects of low adjustment efficiency and poor stability of traditional supports.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0021] 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.

[0022] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 and Figure 2 As shown, an auxiliary support for the construction of industrial silicon ingot molds mainly consists of a left column 1, a right column 2, a crossbeam 4, and connectors 5. Both the left and right columns are vertically arranged elongated plates with multiple holes 3 evenly distributed along their length for connection and fixation. Correspondingly, crossbeams and connectors are mounted on these holes. The crossbeam is a horizontal, elongated rod-like structure, connected at both ends to the upper parts of the left and right columns via connectors. The connectors can move along the length of the column and be fixed in different holes to adjust the height of the crossbeam. The connectors are U-shaped plates with downward-facing openings, and several fan-shaped adjusting plates 51 are fixed on them. Furthermore, both the left and right columns have horizontal, elongated plate-like bases 6 below them to support the support and maintain stability.

[0025] In this embodiment, the connector 5 adopts a U-shaped plate with an opening facing downward (material Q235B, thickness 8mm), combined with a fan-shaped adjustment plate 51 (fan angle 30°, radius 150mm), and multi-angle fine adjustment (adjustment accuracy ±1°) is achieved through the adjustment hole (53). Compared with the traditional straight hole adjustment (such as the commercially available bracket model ZJ-200), the accuracy is improved by 50%.

[0026] When the beam load is 300kg, the maximum stress of the adjusting plate is only 85MPa (Q235B yield strength 235MPa), with a safety factor of 2.7, which meets the GB / T700-2006 standard.

[0027] The clamping component 7 and the sleeve 8 are integrated into one design (the inner diameter of the sleeve is 50mm, which is compatible with the outer diameter of the crossbeam of 48mm). The crossbeam 4 is laterally slidable and vertically fixed by locking bolts (model GB / T5782M12) (sliding resistance ≤10N, displacement after fixing <0.5mm).

[0028] Traditional welded fixed brackets (such as the HX-300 model) require disassembly and reassembly, while this design reduces adjustment time by 70%.

[0029] The base 6 and the left / right columns (1 / 2) are connected by detachable bolts (bolt specification M16×50, strength grade 8.8), which facilitates transportation and site adaptation (the base length can be extended to 3m, which can be adapted to a silicon ingot mold span of 2.5m).

[0030] Dynamic balance design of the fan-shaped adjustment plate:

[0031] The adjustment holes 53 of the fan-shaped adjustment plate 51 are distributed at equal angles (each hole is spaced 5° apart, for a total of 6 holes). The hole layout is optimized through finite element analysis to ensure uniform stress distribution when the beam load is eccentric (maximum eccentric load error <5%).

[0032] Sleeve anti-slip structure:

[0033] The inner wall of sleeve 8 is fitted with polyurethane friction pads (3mm thick, coefficient of friction 0.4), and the locking bolts are pre-tightened to 20kN (refer to VDI2230 standard) to prevent the crossbeam from sliding accidentally.

[0034] The specific quantitative parameters in this implementation outline are as follows:

[0035] Key component selection and process

[0036]

[0037]

[0038] When the sector-shaped adjustment plate 51 is welded to the U-shaped connector 5, the angle tolerance is ±0.5° (calibrated using a Leica AT960 laser tracker).

[0039] Locking bolt preload control:

[0040] Apply a torque of 85 N·m using a torque wrench (model Norbar15073) to ensure that the bolt preload meets the standard (error ≤ 5%).

[0041] The load test data for this device are as follows:

[0042]

[0043] This auxiliary support significantly improves the flexibility and stability of industrial silicon ingot mold construction through a composite adjustment mechanism of U-shaped connectors and fan-shaped adjusting plates, and a linkage locking design of clamping parts and sleeves. During implementation, it is crucial to control the machining accuracy of the fan-shaped plate angle and the pre-tightening force of the locking bolts. It is recommended to use high-precision laser cutting equipment (such as the Trumpf TruLaser 5030) and standardized torque tools (such as the Norbar series) to ensure that the design performance meets the standards. Actual engineering data verifies that it can bear a load of ≥500kg and is suitable for silicon ingot mold sizes of 1-3m, demonstrating significant economic and technical advantages.

[0044] like Figure 2 and Figure 3 As shown, an auxiliary support for the construction of industrial silicon ingot molds features a uniquely designed connector 5. The connector is a U-shaped plate with its opening facing downwards, fixedly connected to several fan-shaped adjusting plates 51. Each plate has mounting holes 52 corresponding to the holes 3 on the left and right columns 1 and 2, respectively. The adjusting plates also have evenly distributed adjusting holes 53. Corresponding clamping components 7 are provided on the outside of each adjusting plate 51. The clamping component on the left column is mechanically connected to the crossbeam 4, while the clamping component on the right column is integrally connected to a sleeve 8 that can move along the crossbeam, near the side of the crossbeam. The clamping component 7 has a through hole 71 that passes through itself and corresponds to the adjusting holes. It is connected to the adjusting plate via a locking bolt structure, achieving stable clamping and flexible adjustment of the crossbeam.

[0045] In one or more feasible embodiments, the different assembly methods of this device and their corresponding adaptations are as follows:

[0046] 1. Standard height assembly (conventional construction method)

[0047] Adjustment components:

[0048] Crossbeam height: Align the mounting holes 52 of the U-shaped connector 5 with the middle holes 3 of the left / right columns (1 / 2) and fix it at a height of 1.5 to 2m (hole spacing 50mm, corresponding to holes 10 to 15).

[0049] Clamping component 7 and sleeve 8: Sleeve 8 slides along the crossbeam 4 to the mid-span position, and the locking bolt (M12) is pre-tightened to a torque of 85 N·m to ensure that the horizontal error of the crossbeam is ≤1 mm / m.

[0050] Applicable scenarios:

[0051] Level the workshop floor and use standard silicon ingot molds (1.5~2m×1.5~2m, weight ≤400kg).

[0052] Quickly define requirements, such as batch masonry operations.

[0053] Case Study:

[0054] A silicon plant in Shandong built a 1.8m silicon ingot mold on a hardened ground. The crossbeam was fixed at the 12th hole (1.8m high), and the sleeve was locked in the center. The construction efficiency was increased by 25%, and the deflection of the crossbeam was only 2.1mm.

[0055] 2. Large-span assembly (extended mode)

[0056] Adjustment components:

[0057] Base 6 extension: The base is extended to 3m (original length 2m) by bolt connection to accommodate silicon ingot molds with larger spans.

[0058] Crossbeam adjustment: Sleeve 8 slides to both sides to the end of crossbeam 4 and is fixed by the fifth hole (angle 25°) of fan-shaped adjustment plate 51 to enhance lateral stability.

[0059] Support reinforcement: Diagonal bracing is added at the connection between the base 6 and the column (1 / 2) (refer to JB / T5000.3 standard).

[0060] Applicable scenarios:

[0061] Large silicon ingot mold (2.5~3m×2.5~3m, weight ≤600kg).

[0062] In situations where the ground bearing capacity is high but the load needs to be distributed.

[0063] Case Study:

[0064] A smelter in Hebei province built a 3m silicon ingot mold with the crossbeam span extended to 3m. The fan-shaped adjustment plate angle was 25° to disperse the stress. When bearing 600kg, the stress on the column was only 180MPa (Q345B allowable stress is 310MPa).

[0065] 3. Adaptive assembly on inclined ground (slope mode)

[0066] Adjustment components:

[0067] Angle compensation of the fan-shaped adjustment plate 51: The adjustment plates 51 of the left and right columns (1 / 2) are selected with different adjustment holes 53 (such as the 3rd hole on the left with a 15° angle and the 5th hole on the right with a 25° angle) to achieve the horizontality of the crossbeam 4.

[0068] Base 6 extended on one side: The base on the lower side of the slope is extended to 2.5m to increase the contact area.

[0069] Clamping component 7 preload adjustment: The torque of the locking bolt on the high slope side is increased to 95 N·m to prevent the crossbeam from slipping.

[0070] Applicable scenarios:

[0071] Gravel or muddy ground with a slope of ≤15° (such as mines and open-air sites).

[0072] Scenarios where rapid leveling is required during temporary construction.

[0073] Case Study:

[0074] Construction was carried out on a 10° slope at a silicon mine in Inner Mongolia. The horizontal level of the crossbeam was compensated by adjusting the angle difference of the plate. The lower side of the base was extended to 2.5m. The overall tilt error of the support was less than 2%, and it could withstand a load of 500kg without instability.

[0075] 4. Tool suspension assembly (auxiliary operation mode)

[0076] Adjustment components:

[0077] The height of the crossbeam 4 is adjusted downwards: it is fixed to the lower hole of the column (1 / 2) (height 0.8-1.2m, hole number 3-6) for easy manual operation.

[0078] Sleeve 8) Position optimization: Slide the sleeve to the end of the crossbeam to release the middle space for hanging tools (hook load capacity 50kg).

[0079] Adjust plate 51 fixed angle: Select 0° hole position (vertical direction) to reduce tool shaking.

[0080] Applicable scenarios:

[0081] Assisting with light operations such as welding and testing (e.g., suspended welding machines, measuring instruments).

[0082] Partial repair or refined construction of silicon ingot molds.

[0083] Case Study:

[0084] A factory in Guangdong installed a Panasonic KR-500 welding machine (40kg) with a crossbeam height of 1m. This increased the daily welding efficiency of the workers by 35% and reduced the time spent picking up and putting down tools by 50%.

[0085] 5. Compact space assembly (narrow environment mode)

[0086] Adjustment components:

[0087] Base 6 can be disassembled and shortened: the extension section is removed, and the base length is reduced to 1.5m (minimum compact form).

[0088] The height of beam 4 is reduced to the minimum: fixed to the bottom hole of the column (1 / 2) (0.5m high, hole number 1).

[0089] Adjust plate 51 retracts inward: Select the -10° hole position to make the U-shaped connector 5 fit tightly against the column, reducing the horizontal space occupied.

[0090] Applicable scenarios:

[0091] Narrow workshops or tunnels (passage width ≤ 2m).

[0092] Small and short silicon ingot molds (height ≤1m) or equipment maintenance.

[0093] In the above solution, through U-shaped connector angle adjustment, sleeve sliding positioning, modular base expansion, and multi-level compensation with fan-shaped adjustment plate, the bracket can achieve five typical assembly modes, covering the following scenarios:

[0094] Size range: 0.5~3m silicon ingot mold;

[0095] Load capacity: 50-600 kg;

[0096] Ground adaptability: From level, hardened ground to 15° slope;

[0097] Functional expansion: from main structure construction to tool suspension and narrow space operations.

[0098] Actual engineering data verify that its adjustment efficiency (≤3 minutes / cycle) and stability (eccentric load error <5%) are significantly better than traditional welded supports, and it has high versatility and economy.

[0099] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
