Description

Technical Field

[0001] This utility model relates to a bagging and unloading device, and in particular to a quick loading and unloading clamping device for soft material bags. Background Technology

[0002] With the rapid development of industry and construction, soft materials such as rock wool and glass wool have been widely used due to their fireproof and thermal insulation properties. However, the production, storage, loading and unloading, transportation, and secondary processing of rock wool and glass wool generally rely on manual handling. This is inefficient and can lead to rock wool and glass wool falling from heights, causing breakage and the release of large amounts of fibers, resulting in dust storms. Dust storms can seriously affect the health of workers. Dust storms involving rock wool and glass wool are most severe during loading, unloading, and storage. Therefore, the relevant background technologies for this specific scenario are categorized as follows:

[0003] The first option is: "Mount a forklift with a hydraulic clamp for loading," see reference. Figure 1 This technical method modifies the hydraulic circuit of the forklift and adds cylinders to drive the side plates, removing the original forks to clamp and release the plates, thus achieving the clamping operation. This method is more efficient than manual loading, reduces labor intensity, improves loading efficiency to some extent, and reduces dust pollution. However, its disadvantages are: A. It requires complex mechanical modifications, resulting in high operating costs. B. This solution requires sufficient space to support forklift movement and turning operations. C. Compared to the product of this invention, the efficiency improvement is very limited; for the capacity of a commonly used 17.5-meter-long heavy semi-trailer trailer, loading stacks is indeed relatively time-consuming. D. Because forklifts are crude machines and clamp multiple items high, neat placement is impossible, still requiring multiple people to cooperate for loading. E. Because this solution only clamps the lower end of the goods, the upper part of the goods is prone to instability when clamping large quantities, and frequent forklift movement below can easily cause the goods to fall, threatening the safety of on-site personnel. F. It requires high operator skill and is difficult to control. G. This technical solution is only suitable for loading. For unloading, the tightly packed bales have no gaps, making it difficult to insert the side steel plates into the gaps for clamping. Therefore, it is not suitable for unloading. The second solution is: "Conveyor belt combined with manual stacking," see reference... Figure 2 This technical solution can only slightly reduce labor intensity, and its disadvantages are: A. Using conveyor belts requires multiple people, resulting in higher costs. B. Manual palletizing requires some personnel to work at heights, and the loose bales are not easy to stand on, posing certain operational risks. C. Dust storms are still likely to occur. D. The efficiency is lower compared to mechanical clamping. Utility Model Content

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example 1, referring to Figures 1-9This utility model discloses a quick loading and unloading clamping device for soft material blocks, comprising a hoisting frame 1, an upper main beam 2, double auxiliary beams 3, a connecting pipe 4, a fixing frame 5, a drum 6, a lower main beam 7, a first retractable wall frame 8, and a second retractable wall frame 9. The upper main beam 2 and the lower main beam 7 are connected and fixedly connected by the double auxiliary beams 3 and the connecting pipe 4, and the drum 6 is fixedly installed in the middle of the double auxiliary beams 3. A steel wire rope 3-2 is wound inside the drum 6, and one side of the drum 6 is connected and fixedly connected to the output end of a forward and reverse motor 3-1; the upper main beam 2... The upper middle part of the upper main beam 2 is fixedly connected to the hoisting frame 1, and the lower end of the lower main beam 7 is fixedly connected to the fixing frame 5. The lower part of the fixing frame 5 is equipped with the support sleeve 5-1 and the support rod 5-2. One end of the upper main beam 2 and the lower main beam 7 is movably telescopically connected to the first retractable wall frame 8, and the other end is movably telescopically connected to the second retractable wall frame 9. The three-sided structure with the lower support formed by the first retractable wall frame 8, the second retractable wall frame 9, the upper main beam 2, the double secondary beams 3, the lower main beam 7, and the support rod 5-2 is used to clamp the soft material block.

[0027] Reference Figure 8 In this utility model, the outer end inner cavity of the upper main beam 2 and the lower main beam 7 are equipped with a main beam telescopic arm 2-2. A connector 2-2-3 is provided at the outer end of the main beam telescopic arm 2-2. The connector 2-2-3 is connected and fixed to the first retractable wall frame 8 and the second retractable wall frame 9 respectively. The main beam telescopic arm return spring 2-2-1 and the telescopic arm return spring transmission rod 2-2-2 are installed below the upper main beam 2, the lower main beam 7 and the main beam telescopic arm 2-2. The main beam telescopic arm 2-2 is stretched outward by the main beam telescopic arm return spring 2-2-1 and the telescopic arm return spring transmission rod 2-2-2.

[0028] The main beam 2 mentioned in this utility model has a fixed pulley 2-1 installed on the lower side of the middle part of the main beam 2. One end of the wire rope 3-2 is wound on the drum 6, and the other end passes around the fixed pulley 2-1 and is connected to the lower part of the connector 2-2-3 at the outer end of the telescopic arm 2-2 of the main beam. The wire rope 3-2 drives the telescopic arm 2-2 of the main beam to retract, thereby realizing the inward clamping action.

[0029] The upper and lower ends of the connecting pipe 4 mentioned in this utility model are respectively installed and fixed on the upper main beam 2 and the lower main beam 7, and are located on both sides of the double auxiliary beam 3. The outer end of the main beam telescopic arm reset spring 2-2-1 is connected to the fixed and immovable connecting pipe 4, and the inner end is connected to the inner end of the telescopic arm reset spring transmission rod 2-2-2, which can slide inward and outward. The inner end of the telescopic arm reset spring transmission rod 2-2-2 is connected to the inner end of the main beam telescopic arm reset spring 2-2-1, and the outer end passes through the transmission rod positioning sleeve 2-3 and is connected to the wire rope 3-2 and the outer end of the main beam telescopic arm 2-2. The main beam telescopic arm reset spring 2-2-1 pulls the telescopic arm reset spring transmission rod 2-2-2 to achieve the outward movement and release action.

[0030] The fixing frame 5 mentioned in this utility model has multiple support sleeves 5-1 evenly installed on the crossbar at the lower end. A support rod 5-2 is installed in each support sleeve 5-1. The support rod 5-2 is inserted into the lower side of the soft material block to provide support.

[0031] In addition, the main beam telescopic arm return spring 2-2-1 and telescopic arm return spring transmission rod 2-2-2 at one end of the upper main beam 2 and lower main beam 7 are fixed to the inner side of the vertical axis, and the other end is fixed to the outer side of the vertical axis. This design is to avoid spatial conflict between the telescopic arm return spring transmission rod 2-2-2 on both sides and the main beam telescopic arm return spring 2-2-1 sliding inside and outside during coordinated horizontal axial movement.

[0032] The aforementioned main beam fixed pulley 2-1 is provided with four sets, two of which are installed on the lower side of the middle of the upper main beam 2, and the other two are installed on the upper side of the middle of the lower main beam 7.

[0033] The aforementioned transmission rod positioning sleeve 2-3 has four parts that are respectively fixed to the middle of the upper main beam 2 and the lower main beam 7 at the outer side. The upper and lower positions are located at the working axis of the telescopic arm return spring transmission rod 2-2-2 sliding inside and outside, which is used to stabilize its connection with the main beam telescopic arm return spring 2-2-1 and its axial movement.

[0034] When using this utility model,

[0035] The first step is to connect the overhead crane hook to the lifting frame 1 of this utility model; move this utility model behind the rock wool and glass wool cargo block at the rear of the truck using the overhead crane, adjust the height and bring it close to the cargo. At this time, this utility model is in the extended state, forming a three-sided enclosure of the cargo block from the rear, left and right; control the insertion of the pointed support rod 5-2 into the lower part of the cargo block to support the weight of the stack of blocks falling.

[0036] The second step (analysis of the contraction process) involves starting the forward and reverse motor 3-1. The wire rope 3-2 is tightened and wound along the drum 6. Then, the vertical tension is changed to a horizontal tension on both sides towards the center axis through the main beam fixed pulley 2-1. This causes the main beam telescopic arm 2-2, connected to the outer end of the wire rope 3-2, to retract inward under tension. Since the outer end of the main beam telescopic arm 2-2 is also connected to the outer end of the telescopic arm return spring transmission rod 2-2-2, the outer end of the telescopic arm return spring transmission rod 2-2-2 also simultaneously retracts horizontally inward. The movement is achieved by a fixed-length rigid rod. Its inner end is pushed and moved horizontally inwards. This inner end is connected to the inner end of the main beam telescopic arm return spring 2-2-1, while the outer end of the main beam telescopic arm return spring 2-2-1 is fixed to the immovable connecting pipe 4. This prevents the outer end of the main beam telescopic arm return spring 2-2-1 from moving, while the inner end is pushed and driven by the connecting movement of the inner end of the telescopic arm return spring transmission rod 2-2-2, causing the main beam telescopic arm return spring 2-2-1 to be stretched and stored. Since all components move synchronously, the main beam telescopic arm 2-2 also drives the first retractable wall frame 8 and the second retractable wall frame 9 to tighten inwards. At this time, the cargo bundle is tightly clamped on both sides; while the overhead crane lifts this utility model, the bundle is smoothly clamped and moved to the required position before being lowered.

[0037] The third step (explanation of the extension process) involves the reversible motor 3-1, which is controlled by a momentary press of the button to start and automatically locks when the button is released. This causes the motor 3-1 to continuously pull the steel wire rope 3-2 after starting, maintaining a tension-resistance relationship with the extended and force-accumulating main beam telescopic arm return spring 2-2-1. Since the motor's tension is greater than that of the main beam telescopic arm return spring 2-2-1, the pulling and retraction of the main beam telescopic arm return spring 2-2-1 can be achieved by rotating the motor 3-1 in either the forward or reverse direction. Press and hold the reverse start button of the forward and reverse motor 3-1 to drive the drum 6 to reverse, slowly releasing the wire rope 3-2. At this moment, the wire rope 3-2 is slack, but the instantaneous release releases the stored tension of the main beam telescopic arm return spring 2-2-1, causing the tension of the spring to be released instantaneously. Since it is fixed to the outer end of the connecting pipe 4 as a fixed point and cannot move, the length continues to shorten to the outer end, which drives the inner end of the telescopic arm return spring transmission rod 2-2-2 connected to the inner end to move to the outer end. Since the outer end of the telescopic arm return spring transmission rod 2-2-2 is connected to the outer end of the main beam telescopic arm 2-2, it drives the main beam telescopic arm 2-2 and the retraction frame to move outward until the length of the main beam telescopic arm return spring 2-2-1 returns to its original state. Release the reverse start button of the forward and reverse motor 3-1 to achieve the extended state.

[0038] Example 2: The technical solution of the quick loading and unloading clamping device for soft material blocks mentioned in this utility model is as follows: it includes a hoisting frame 1, an upper main beam 2, double secondary beams 3, a connecting pipe 4, a fixing frame 5, a drum 6, a lower main beam 7, a first retractable wall frame 8, and a second retractable wall frame 9. The upper main beam 2 and the lower main beam 7 are connected and fixedly connected by the double secondary beams 3 and the connecting pipe 4. The drum 6 is fixedly installed in the middle of the double secondary beams 3. The drum 6 is wound with steel wire rope 3-2. One side of the drum 6 is connected and fixedly connected to the output end of the forward and reverse motor 3-1. The upper main beam 2 is fixedly connected to the middle of the upper side of the hoisting frame 1, and the lower main beam 7 is fixedly connected to the fixing frame 5. The fixing frame 5 is equipped with the support sleeve 5-1 and the support rod 5-2 at the lower part. One end of the upper main beam 2 and the lower main beam 7 is movably telescopically connected to the first retractable wall frame 8, and the other end is movably telescopically connected to the second retractable wall frame 9. The three-sided structure with the lower support formed by the first retractable wall frame 8, the second retractable wall frame 9, the upper main beam 2, the double secondary beams 3, the lower main beam 7, and the support rod 5-2 is used to clamp the soft material block.

[0039] The first retractable wall frame 8 and the second retractable wall frame 9 are respectively composed of two longitudinal bars and multiple transverse bars welded together. One end of each of the two transverse bars is provided with a connecting rod, which is fixed to the connector 2-2-3 at the outer end of the main beam telescopic arm 2-2 by inserting a top screw into the connecting rod.

[0040] In addition, multiple support sleeves 5-1 are evenly installed on the crossbar at the lower end of the fixing frame 5. Depending on the site conditions, support rods 5-2 can be installed in some of the support sleeves 5-1. One end of the support rod 5-2 is pointed, and in use, the pointed support rod 5-2 can be directly inserted into the soft material block to achieve support and fixation.

[0041] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the above-described technical solution. Therefore, any simple modifications or equivalent transformations made based on the technical solution of this utility model, including but not limited to simple replacement of the transmission principle with the same or similar clamping or insert form, such as hydraulic transmission, motor screw transmission, etc., are all within the scope of protection claimed by this utility model.
