Description

Technical Field

[0001] This utility model relates to the field of furnace body replacement technology, specifically an auxiliary tooling for hoisting furnace bodies. Background Technology

[0002] The high-temperature furnace in photovoltaic cell manufacturing is a core piece of equipment that ensures cell performance and directly affects cell efficiency and yield. During long-term use, the furnace may experience heating abnormalities or damage, requiring replacement.

[0003] Due to limited working space for replacing the furnace body, a trolley is needed to lift the furnace body during replacement, and a hand chain hoist is needed to hoist it. The process furnace consists of 6 furnace bodies. Replacing 1-5 furnace bodies can be done using a trolley and a hand chain hoist. When installing the last furnace body, the hand chain hoist will interfere with the previously installed furnace body and cannot be used. Only a trolley can be used for the operation.

[0004] However, the forklift cannot fully enter the space between the machine and the frame, making it dangerous to use the forklift to lift the furnace body. This requires more workers, and the large lifting and pushing range can easily cause injury to workers.

[0005] Therefore, an auxiliary tooling for hoisting the furnace body is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An auxiliary tooling for hoisting a furnace body, comprising a U-shaped base; the U-shaped base is bolted to the top of the machine platform; a winding rod is rotatably mounted on the top of the U-shaped base; couplings are bolted to both ends of the winding rod; one end of the winding rod is connected to a motor via a coupling; cantilever arms are rotatably mounted on both sides of the U-shaped base; a guide rod is rotatably mounted between the ends of the cantilever arms away from the U-shaped base; a rope is fixed to the outer ring of the winding rod; the rope passes around the guide rod.

[0008] Preferably, a winding wheel is fixedly connected to the outer ring of the middle portion of the winding rod; the rope is wound around the outer ring of the middle portion of the winding wheel; a guide wheel is rotatably mounted on the outer ring of the middle portion of the guide rod; and the rope passes over the top outer ring of the guide wheel.

[0009] Preferably, a pressure bar is bolted inside the winding reel to press down the rope.

[0010] Preferably, the outer ring of the guide rod is fitted with a pair of fixing rings; the two fixing rings are respectively located on both sides of the guide wheel.

[0011] Preferably, a rotating seat is bolted to both sides of the U-shaped base 1; the cantilever is rotatably connected to the rotating seat; a panel is fixed to the bottom of both sides of the U-shaped base 1; a hydraulic cylinder is fixed to the top surface of the panel; and a support member for supporting the bottom of the cantilever is provided on the top of the piston rod of the hydraulic cylinder.

[0012] Preferably, the support includes a first mounting seat bolted to the top of the piston rod of the hydraulic cylinder; a U-shaped bracket is threaded onto the top of the first mounting seat; the inner wall of the U-shaped bracket engages with the outer wall of the bottom of the cantilever.

[0013] Preferably, the support includes a second mounting seat bolted to the top of the piston rod of the hydraulic cylinder; a ball joint rod is threaded onto the top of the second mounting seat; a ball seat is rotatably mounted on the outer ring of the top of the ball joint rod; and the ball seat is bolted to the bottom surface of the cantilever.

[0014] Preferably, a graduated ring is fixed to the outer ring of the rotating base on the side closest to the U-shaped base.

[0015] The advantages of this utility model are:

[0016] 1. The auxiliary tooling for hoisting a furnace body according to this utility model comprises a U-shaped base, winding rods, couplings, cantilever, guide rods, and ropes. Multiple winding rods of the auxiliary tooling are connected in series using the couplings and connecting rods, and a motor is connected to one end of the winding rod. Multiple ropes are fixedly connected to both ends and the middle of the furnace body. The motor drives multiple winding rods to rotate synchronously through the couplings, simultaneously winding multiple ropes onto their respective winding rods. Guided by the guide rods, the ropes hoist the furnace body vertically upwards, facilitating the hoisting of furnace bodies of different weights, reducing the number of personnel required, and the synchronous movement of multiple ropes helps maintain the furnace body's balance, reducing the risk of the furnace body falling.

[0017] 2. The auxiliary tooling for hoisting the furnace body described in this utility model includes a rotating base, a panel, a hydraulic cylinder, and a support component. The hydraulic cylinder pushes the support component to rise and fall, which in turn pushes the cantilever to rotate and rise and fall around the rotating base, thereby controlling the guide rod to rise and fall. This facilitates the control of the hoisting height when hoisting the furnace body, and thus facilitates the installation work of the workers. Attached Figure Description

[0029] 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 scope of protection of the present utility model.

[0030] like Figures 1 to 2 As shown, an auxiliary tooling for hoisting a furnace body includes a U-shaped base 1; the U-shaped base 1 is bolted to the top of the machine platform; a winding rod 2 is rotatably mounted on the top of the U-shaped base 1; couplings 3 are bolted to both ends of the winding rod 2; one end of the winding rod 2 is connected to a motor via the coupling 3; cantilever arms 4 are rotatably mounted on both sides of the U-shaped base 1; a guide rod 5 is rotatably mounted between the ends of the cantilever arms away from the U-shaped base 1; a rope 6 is fixed to the outer ring of the winding rod 2; the rope 6 passes around the guide rod 5.

[0031] Specifically, a stepped hole is provided in the middle of the bottom surface of the U-shaped base 1, and screws are used to fix it to the machine base through the stepped hole; through holes are provided at corresponding positions on the top of both sides of the U-shaped base 1, and the two ends of the winding rod 2 pass through the through holes on both sides of the U-shaped base 1, and bearings are provided between the winding rod 2 and the through holes.

[0032] Based on the actual weight of the furnace body, select an appropriate number of auxiliary tools for simultaneous use. That is, connect the winding rods 2 of multiple auxiliary tools in series with couplings 3 and connecting rods, and connect the winding rods 2 at one end to a motor so that the motor can drive multiple winding rods 2 to rotate synchronously.

[0033] In actual operation, select an appropriate number of auxiliary tools according to factors such as the weight and length of the furnace body; use screws to fix the U-shaped base 1 to the machine platform, so that the cantilever 4 drives the guide rod 5 to extend out of the machine platform, so that the rope 6 passes around the guide rod 5 and hangs down to the furnace body placed on the ground; use the coupling 3 and the connecting rod to connect the winding rods 2 of multiple auxiliary tools in series, and connect the motor to the winding rod 2 at one end; fix multiple ropes 6 to the two ends and the middle of the furnace body respectively;

[0034] The motor drives multiple winding rods 2 to rotate synchronously through the coupling 3, and simultaneously winds multiple ropes 6 onto their respective winding rods 2. The ropes 6 are guided by the guide rod 5, so that the ropes 6 lift the furnace body vertically upward, which makes it easier to lift furnace bodies of different weights, reduces the number of workers, and the synchronous movement of multiple ropes 6 helps to keep the furnace body balanced, reducing the possibility of the furnace body falling.

[0035] Furthermore, such as Figures 1 to 4As shown, a winding wheel 7 is fixedly connected to the outer ring of the middle part of the winding rod 2; the rope 6 is wound around the outer ring of the middle part of the winding wheel 7; a guide wheel 8 is rotatably installed on the outer ring of the middle part of the guide rod 5; the rope 6 passes over the top outer ring of the guide wheel 8.

[0036] Specifically, the outer rings of both ends of the winding wheel 7 are provided with multiple threaded holes, and the internal threads of the threaded holes are used to install screws, and the ends of the screws are provided with internal hexagonal grooves.

[0037] The rope 6 is wound up by the winding wheel 7 and guided by the guide wheel 8, thus confining the rope 6 to the middle of the winding rod 2 and the guide rod 5. This ensures that the movement direction and position of each rope 6 are consistent, thereby effectively improving the stability of hoisting the furnace body.

[0038] Furthermore, such as Figures 1 to 4 As shown, a pressure rope strip 9 for pressing down the rope 6 is bolted inside the winding wheel 7;

[0039] Specifically, slots are provided on both sides of the inside of the winding wheel 7, and the two ends of the pressure rope 9 are slidably installed inside the slots, and the two ends of the pressure rope 9 are locked inside the slots by screws.

[0040] The rope 6 is clamped and fixed by the pressure rope 9 in conjunction with the outer ring of the winding wheel 7, so that the rope 6 can be wound onto the outer ring of the winding wheel 7; at the same time, the rope 6 is fixed by the pressure rope 9, which makes it easier for the staff to control and adjust the length of the rope 9, thereby making it easier for the staff to keep the length of the rope 9 for hoisting the furnace body consistent, and thus making the hoisting speed of each part of the furnace body consistent.

[0041] Furthermore, such as Figures 1 to 4 As shown, a pair of fixing rings 10 are fitted around the outer ring of the guide rod 5; the two fixing rings 10 are respectively located on both sides of the guide wheel 8;

[0042] Specifically, the outer ring of the fixing ring 10 is provided with multiple threaded holes, and a screw is installed in the internal thread of the threaded holes. The end of the screw is provided with an internal hexagonal groove. The fixing ring 10 is fixed and locked to the outer ring of the guide rod 5 by pressing the outer wall of the guide rod 5 with the screw.

[0043] Two retaining rings 10 are fixed and locked to both sides of the guide wheel 8, restricting the guide wheel 8 to the middle of the guide rod 5, thereby preventing the guide wheel 8 from shifting during rotation.

[0044] In some embodiments, such as Figure 1 , Figure 2 and Figure 5As shown, a rotating seat 11 is bolted to both sides of the U-shaped base 1; the cantilever 4 is rotatably connected to the rotating seat 11; a panel 12 is fixed to the bottom of both sides of the U-shaped base 1; a hydraulic cylinder 13 is fixed to the top surface of the panel 12; a support member for supporting the bottom of the cantilever 4 is provided on the top of the piston rod of the hydraulic cylinder 13.

[0045] Specifically, screw holes are provided at corresponding positions on the outer periphery of the swivel base 11 and the two sides of the U-shaped base 1, and screws are installed inside the screw holes. The swivel base 11 is fixedly installed to the side of the U-shaped base 1 by the screws. A protruding post is fixedly connected to the middle of the side of the swivel base 1 away from the U-shaped base 1. A round hole is provided at the end of the cantilever 4 near the U-shaped base 1, and the round hole is sleeved on the outer ring of the protruding post through a bearing, so that the cantilever 4 can rotate.

[0046] The hydraulic cylinder 13 pushes the support component to lift and lower, and pushes the cantilever 4 to rotate and lift around the rotating seat 11, thereby controlling the guide rod 5 to lift and lower; thus facilitating the control of the lifting height when hoisting the furnace body, and thus facilitating the installation work of the staff.

[0047] In some embodiments, such as Figure 6 and Figure 7 As shown, the support includes a first mounting seat 14a bolted to the top of the piston rod of the hydraulic cylinder 13; a U-shaped bracket 15 is threaded onto the top of the first mounting seat 14a; the inner wall of the U-shaped bracket 15 engages with the bottom outer wall of the cantilever 4.

[0048] Specifically, the bottom outer ring of the first mounting base 14a has a straight groove, and the first mounting base 14a is fixedly installed to the top of the piston rod of the hydraulic cylinder 13 by screws passing through the straight groove; an internally threaded mounting cylinder is fixedly connected to the middle of the first mounting base 14a.

[0049] The U-shaped bracket 15 has an overall U-shaped structure, with a horizontal cylindrical structure at the bottom and vertical plate-like structures on both sides; the bottom of the U-shaped bracket 15 is fixed with a stud that matches the internal threaded mounting cylinder of the first mounting base 14a.

[0050] The bottom of the cantilever 4 is supported by the U-shaped bracket 15. Since the bottom of the U-shaped bracket 15 is cylindrical, the U-shaped bracket 15 can always stably fit the bottom of the cantilever 4, thereby ensuring stable support for the cantilever 4. At the same time, the vertical plate-like structures on both sides of the U-shaped bracket 15 can effectively limit the position of the cantilever 4 and improve the stability of the cantilever 4 rotation.

[0051] In some embodiments, such as Figure 8 and Figure 9As shown, the support includes a second mounting seat 14b bolted to the top of the piston rod of the hydraulic cylinder 13; a ball head rod 16 is threaded onto the top of the second mounting seat 14b; a ball head seat 17 is rotatably mounted on the outer ring of the top of the ball head rod 16; and the ball head seat 17 is bolted to the bottom surface of the cantilever 4.

[0052] Specifically, the bottom outer ring of the second mounting base 14b has a straight groove, and the second mounting base 14b is fixedly installed to the top of the piston rod of the hydraulic cylinder 13 by screws passing through the straight groove; an internally threaded mounting cylinder is fixedly connected to the middle of the second mounting base 14b.

[0053] The ball head 16 consists of a threaded rod at the bottom and a ball head at the top; the threaded rod at the bottom of the ball head 16 is threadedly fixed inside the internal threaded mounting sleeve of the second mounting base 14b; a ball groove matching the ball head of the ball head 16 is provided in the middle of the bottom surface of the ball head seat 17.

[0054] By allowing the ball joint rod 16 to rotate flexibly inside the ball joint seat 17, the hydraulic cylinder 13 is connected to the cantilever 4. When the hydraulic cylinder 13 pushes the cantilever 4 to rotate, the ball joint rod 16 between the cantilever 4 and the hydraulic cylinder 13 will also flexibly adjust its angle in the ball joint seat 17, thereby improving the flexibility of the cantilever 4.

[0055] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, a scale ring 18 is fixedly connected to the outer ring of the rotating base 11 on the side close to the U-shaped base 1;

[0056] Specifically, the scale ring 18 is fixed to the outer ring of the rotating base 11, and angle lines are arranged around the scale ring 18, with the 0° and 180° scale lines set at a position that is horizontal with the bottom surface of the U-shaped base 1.

[0057] The scale line 18 is used to compare the cantilever 4 and display the tilt angle of the cantilever 4, which facilitates accurate control of the rotation of the cantilever 4 and improves the accuracy of furnace installation.

[0058] Working principle: Select an appropriate number of auxiliary tools based on factors such as the weight and length of the furnace body; use screws to fix the U-shaped base 1 to the machine base, so that the cantilever 4 drives the guide rod 5 to extend out of the machine base; use the coupling 3 and connecting rod to connect the winding rods 2 of multiple auxiliary tools in series, and connect the motor to the winding rod 2 at one end;

[0059] The rope 6 is clamped and fixed by the pressure rope 9 in conjunction with the middle outer ring of the winding wheel 7, so that the rope 6 can be wound onto the outer ring of the winding wheel 7; the guide wheel 8 is used to guide the rope 6, so that the rope 6 passes around the guide rod 5 and falls down to the furnace body placed on the ground.

[0060] The hydraulic cylinder 13 is used to push the support component to rise and fall, and push the cantilever 4 to rotate and rise around the turntable 11, thereby controlling the guide rod 5 to rise and fall; controlling the hoisting height when hoisting the furnace body;

[0061] The motor drives multiple winding rods 2 to rotate synchronously through coupling 3, which in turn winds multiple ropes 6 onto their respective winding wheels 7. The ropes 6 are guided by guide wheels 8, so that the ropes 6 lift the furnace body vertically upward. This makes it easier to lift furnace bodies of different weights, reduces the number of workers, and the synchronous movement of multiple ropes helps to keep the furnace body balanced, reducing the chance of the furnace body falling.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
