Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial tank opening equipment, and in particular to a plug pulling device. BACKGROUND

[0002] In industrial production, industrial tanks are widely used for storing various raw materials, semi-finished products and finished products. These industrial tanks are usually sealed with tank plugs. Due to the large volume of industrial tanks and the tight sealing of tank plugs, the traditional manual opening method not only requires a lot of manpower and is inefficient, but also the operator is likely to be injured due to improper force during the opening process, which poses a great safety hazard.

[0003] Currently, there are some tank opening tools for industrial tanks on the market, but most of them have the problem of not adapting to the characteristics of industrial tanks in structure design. The carrying capacity of some tools is insufficient, which cannot meet the opening needs of large industrial tanks; some tools have poor stability during operation, which can easily cause the industrial tank to shake and may cause safety accidents such as material leakage, and the range of applicable industrial tank specifications is narrow, which is difficult to meet the diversified needs of different industrial scenes.

[0004] Therefore, it is necessary to design a plug pulling device with stable structure, strong carrying capacity, safe and convenient operation, and wide application range according to the characteristics of industrial tanks. SUMMARY

[0005] To solve the technical problems in the background art, the present application provides a plug pulling device.

[0006] The plug pulling device provided by the present application comprises a tank body, a stand, a cross frame and a clamp, a tank plug is inserted into the tank opening of the tank body, the clamp is locked on the outer sidewall of the tank plug through the cooperation of bolts and nuts, and the outer wall of the clamp is provided with a plurality of groups of butt joints;

[0007] The stand is provided with two groups, and a top frame is connected between the top parts of the two groups of stands, the tank body is placed between the two groups of stands and below the top frame;

[0008] The middle part of the stand is provided with a limiting frame, and the limiting frame is used for limiting the upper part of the tank body;

[0009] The top side of the top frame is axially rotatably connected with a nut, and the two sides of the nut are fixedly connected with connecting rods;

[0010] The nut is internally threadedly connected with a screw rod, the top part of the screw rod extends above the top frame, the bottom part of the screw rod extends below the top frame, the middle part of the cross frame is fixedly connected to the bottom part of the screw rod, and the two ends of the cross frame are fixedly connected with chains; the ends of the chains are connected with the butt joints.

[0011] Preferably, each of the connecting rods is vertically mounted with a handle, and the surface of the handle is provided with an anti-slip sleeve to facilitate the operator's grip when operating with force.

[0012] Preferably, the limiting frame is provided with a velvet cloth to enhance the friction between it and the industrial tank, prevent the large industrial tank from shifting during the plug removal process, and fix the tank to prevent it from moving upward, thereby separating the plug from the tank.

[0013] Preferably, the limiting frame can slide in the vertical direction of the upright and is positioned by a positioning mechanism, and can be flexibly adjusted according to industrial tanks of different heights.

[0014] Preferably, the positioning mechanism includes multiple positioning holes formed on the side wall of the upright and elastic locking pins installed on the limiting frame. The multiple positioning holes are distributed at intervals along the vertical direction of the upright. The elastic locking pins are adapted to the positioning holes. When the limiting frame slides to the target position, the elastic locking pins are engaged in the corresponding positioning holes to achieve positioning and ensure the limiting effect on the industrial tank.

[0015] Preferably, both sets of uprights are provided with side plates, and vertical slide rails are provided on the side plates. The two ends of the cross frame are vertically slidably connected to the corresponding slide rails to ensure that the cross frame moves smoothly when pulling the industrial tank stopper and plays a vertical guiding role.

[0016] Preferably, a hook is provided at the connection between the chain and the crossbar. The hook is detachably connected to the crossbar and fixedly connected to the chain. The chain and the crossbar are detachably connected by a high-strength hook, which facilitates the replacement of chains of different lengths or load-bearing capacities according to the size and shape of the industrial tank stopper, further improving the flexibility of the device in industrial scenarios.

[0017] Preferably, the top of the screw is provided with a stop block, the diameter of which is larger than the diameter of the screw, to limit the maximum downward stroke of the screw.

[0018] Preferably, the bottom of the support frame is equipped with casters, which are heavy-duty casters with braking function. This facilitates the movement of the device within the industrial site and allows it to be fixed during operation, thus combining convenience and stability and adapting to the complex environment of industrial production.

[0019] Preferably, the inner wall of the clamp is provided with anti-slip texture to enhance the locking force between the clamp and the can stopper. The thickened fleece on the limiting frame and the deepened anti-slip texture on the inner side of the clamp significantly enhance the friction, effectively preventing the industrial can from shaking or slipping during the stopper removal process, improving the stability and safety of industrial operation, and reducing the risk of accidents such as material leakage.

[0020] The present invention proposes a plug-removing device. The key components such as the frame, screw, and chain are made of high-strength materials, which can withstand the weight of the industrial can and the huge pulling force when removing the plug. It is specially adapted to the use of industrial cans. Through reasonable structural design and lever principle, the plug of the industrial can is easily removed, which greatly reduces the labor intensity of operators and improves industrial production efficiency.

[0021] The limiting frame can slide vertically on the stand and be positioned by a high-strength positioning mechanism. It can be adjusted according to industrial tanks of different heights, thus expanding the applicability of the device to industrial tanks of different specifications.

[0032] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Example 1

[0034] like Figures 1-2The illustrated plug removal device includes an industrial tank 5, a vertical frame 1, a horizontal frame 201, and a clamp 3. A plug 501 is inserted into the opening of the industrial tank 5. The clamp 3 is locked to the outer wall of the plug 501 by a high-strength bolt 2 and a nut 4. The inner wall of the clamp 3 is provided with a deepened anti-slip texture to enhance the locking force between the clamp 3 and the plug 501. The outer wall of the clamp 3 is provided with multiple sets of high-strength mating parts.

[0035] The support frame 1 has two sets, which are made of high-strength steel. The top of the two sets of support frames 1 is connected by a top frame 102. The industrial tank 5 is placed between the two sets of support frames 1 and below the top frame 102. The bottom of the support frame 1 is equipped with heavy-duty mobile wheels with braking function, which facilitates the movement of the device in the industrial site and can be braked and fixed during operation.

[0036] A limiting frame 101 is installed in the middle of the upright frame 1. The limiting frame 101 is used to limit the upper part of the industrial tank 5. The limiting frame 101 is covered with thickened fleece to enhance the friction between it and the industrial tank 5. The limiting frame 101 can slide in the vertical direction of the upright frame 1 and is positioned by a positioning mechanism. The positioning mechanism includes multiple positioning holes opened in the side wall of the upright frame 1 and high-strength elastic pins installed on the limiting frame 101. The multiple positioning holes are distributed at intervals along the vertical direction of the upright frame 1. The elastic pins are adapted to the positioning holes. When the limiting frame 101 slides to the target position, the elastic pins engage with the corresponding positioning holes to achieve positioning.

[0037] A nut is axially rotatably connected to the middle of the top side of the top frame 102. Connecting rods 401 are fixedly connected to both sides of the nut. The connecting rods 401 serve to extend the power arm. A handle 402 is vertically installed at the end of each connecting rod 401. The surface of the handle 402 is provided with an anti-slip sleeve.

[0038] The nut is internally threaded with a screw rod made of high-strength alloy material. Its top extends above the top frame 102 and its bottom extends below the top frame 102. The top of the screw rod is provided with a stop block made of wear-resistant material. The diameter of the stop block is larger than the diameter of the screw rod, which is used to limit the maximum downward stroke of the screw rod.

[0039] The middle part of the cross frame 201 is fixedly connected to the bottom of the screw. Both ends of the cross frame 201 are fixedly connected to high-strength chains 202. The ends of the chains 202 are connected to various docking parts. A high-strength hook is provided at the connection between the chain 202 and the cross frame 201. The hook is detachably connected to the cross frame 201 and is fixedly connected to the chain 202.

[0040] Working principle: In use, the device is moved to the side of the industrial tank 5 using the heavy-duty moving wheels with braking function at the bottom of the upright frame 1, and the moving wheels are braked to fix the device. The position of the limiting frame 101 is adjusted according to the height of the industrial tank 5. The high-strength elastic locking pin is pressed to disengage it from the positioning hole. After sliding the limiting frame 101 to the appropriate position, the elastic locking pin is released to lock it into the corresponding positioning hole to achieve positioning. The industrial tank 5 is placed between the two sets of upright frames 1, so that the limiting frame 101 stabilizes and limits the upper part of the industrial tank 5, preventing the tank 5 from moving upward during the plug removal process.

[0041] Then, the clamp 3 is locked to the outer wall of the can stopper 501 by the high-strength bolt 2 and the nut 4. The locking effect is enhanced by the deepened anti-slip texture on the inner side of the clamp 3. The end of the high-strength chain 202 is connected to the high-strength mating part on the clamp 3. The chain 202 is connected to the cross frame 201 by the high-strength hook.

[0042] The operator grips the handle 402 with the anti-slip sleeve and rotates the connecting rod 401. The connecting rod 401 extends the power arm, making operation easier and causing the nut to rotate. Since the nut is threadedly connected to the high-strength screw, the rotation of the nut causes the screw to move upward, which in turn causes the crossbeam 201 to move upward. During this process, the bolt 2 rotates along with the chain 202. The chain 202 may become tangled until it straightens. Then, the bolt 2 slowly rises, pulling the clamp 3 and the can plug 501 upward through the high-strength chain 202. Under the action of the limit frame 101 fixing the can body 5, the can plug 501 separates from the can body 5, thus pulling the can plug 501 out of the industrial can body 5.

[0043] During the plug removal process, the thickened velvet on the limit frame 101 enhances the friction between the limit frame and the industrial tank 5, preventing the industrial tank 5 from shaking; the stop block limits the maximum stroke of the screw downward movement, avoiding damage caused by excessive downward movement of the screw, and ensuring the stable operation of the device in the industrial environment.

[0044] Example 2

[0045] like Figure 3 As shown:

[0046] A plug removal device includes an industrial tank body 5, a vertical frame 1, a horizontal frame 201, and a clamp 3. A plug 501 is inserted into the opening of the industrial tank body 5. The clamp 3 is locked to the outer wall of the plug 501 by a high-strength bolt 2 and a nut 4. The inner wall of the clamp 3 is provided with a deepened anti-slip texture to enhance the locking force between the clamp 3 and the plug 501. The outer wall of the clamp 3 is provided with multiple sets of high-strength mating parts.

[0047] The upright frame 1 has two sets, which are made of high-strength steel. The top of the two sets of upright frames 1 is connected by a top frame 102. The industrial tank 5 is placed between the two sets of upright frames 1 and below the top frame 102. The bottom of the upright frame 1 is equipped with heavy-duty mobile wheels with braking function, which facilitates the movement of the device in the industrial site. It can be braked and fixed during operation. Both sets of upright frames 1 are equipped with side plates 103, which are made of thickened steel plates. Vertical slide rails 104 are opened on the side plates 103 to play a vertical guiding role.

[0048] A limiting frame 101 is installed in the middle of the upright frame 1. The limiting frame 101 is used to limit the upper part of the industrial tank 5. The limiting frame 101 is covered with thickened fleece to enhance the friction between it and the industrial tank 5. The limiting frame 101 can slide in the vertical direction of the upright frame 1 and is positioned by a positioning mechanism. The positioning mechanism includes multiple positioning holes opened in the side wall of the upright frame 1 and high-strength elastic pins installed on the limiting frame 101. The multiple positioning holes are distributed at intervals along the vertical direction of the upright frame 1. The elastic pins are adapted to the positioning holes. When the limiting frame 101 slides to the target position, the elastic pins engage with the corresponding positioning holes to achieve positioning.

[0049] A nut is axially rotatably connected to the middle of the top side of the top frame 102. Connecting rods 401 are fixedly connected to both sides of the nut. The connecting rods 401 serve to extend the power arm. A handle 402 is vertically installed at the end of each connecting rod 401. The surface of the handle 402 is provided with an anti-slip sleeve.

[0050] The nut is internally threaded with a screw rod made of high-strength alloy material. Its top extends above the top frame 102 and its bottom extends below the top frame 102. The top of the screw rod is provided with a stop block made of wear-resistant material. The diameter of the stop block is larger than the diameter of the screw rod, which is used to limit the maximum downward stroke of the screw rod.

[0051] The middle part of the cross frame 201 is fixedly connected to the bottom of the screw. The two ends of the cross frame 201 are vertically slidably connected to the corresponding slide rails 104. High-strength chains 202 are fixedly connected to both ends of the cross frame 201. The ends of the chains 202 are connected to the various docking parts. High-strength hooks are provided at the connection between the chains 202 and the cross frame 201. The hooks are detachably connected to the cross frame 201 and are fixedly connected to the chains 202.

[0052] Working principle: In use, the device is moved to the side of the industrial tank 5 using the heavy-duty moving wheels with braking function at the bottom of the upright frame 1, and the moving wheels are braked to fix the device. The position of the limiting frame 101 is adjusted according to the height of the industrial tank 5. The high-strength elastic locking pin is pressed to disengage it from the positioning hole. After sliding the limiting frame 101 to the appropriate position, the elastic locking pin is released to lock it into the corresponding positioning hole to achieve positioning. The industrial tank 5 is placed between the two sets of upright frames 1, so that the limiting frame 101 stabilizes and limits the upper part of the industrial tank 5, preventing the tank 5 from moving upward during the plug removal process.

[0053] Then, the clamp 3 is locked to the outer wall of the can stopper 501 by the high-strength bolt 2 and the nut 4. The locking effect is enhanced by the deepened anti-slip texture on the inner side of the clamp 3. The end of the high-strength chain 202 is connected to the high-strength mating part on the clamp 3. The chain 202 is connected to the cross frame 201 by the high-strength hook.

[0054] The operator grips the handle 402 with its anti-slip sleeve and rotates the connecting rod 401. The connecting rod 401 extends the power arm, making operation easier and causing the nut to rotate. Since the nut is threadedly connected to the high-strength screw, the rotation of the nut causes the screw to move upward, which in turn causes the crossbeam 201 to move upward. The crossbeam 201 slides smoothly vertically within the slide rail 104 of the side plate 103, achieving vertical guidance. During this process, the chain 202 does not rotate or become entangled; it only moves vertically with the crossbeam 201. After straightening, the high-strength chain 202 pulls the clamp 3 and the can plug 501 upward. Under the action of the limiting frame 101 fixing the can body 5, the can plug 501 separates from the can body 5, thereby pulling the can plug 501 out of the industrial can body 5.

[0055] During the plug removal process, the thickened velvet on the limit frame 101 enhances the friction between the limit frame and the industrial tank 5, preventing the industrial tank 5 from shaking; the stop block limits the maximum stroke of the screw downward movement, avoiding damage caused by excessive downward movement of the screw, and ensuring the stable operation of the device in the industrial environment.
