Description

Technical Field

[0001] This application relates to the field of welding and fixing device technology, and in particular to an intelligent building curtain wall installation and connection device and control method. Background Technology

[0002] Intelligent building curtain walls are the product of combining traditional building curtain walls with modern information technology, automation control, and materials science. They are intelligent building envelope structures that achieve goals such as energy saving, comfort, and safety by sensing environmental changes and dynamically adjusting performance. Their structure includes both the supporting frame and panels of traditional curtain walls, as well as special components such as sensors required for intelligentization.

[0003] When connecting the horizontal and vertical keels in the support frame, corner brackets are usually welded to one side of the vertical keel. One end of the horizontal keel is then placed over the corner bracket, and the horizontal keel is fixed by a welding connection device. The other end of the horizontal keel is then welded to the vertical keel by welding equipment.

[0004] When existing welding connection devices are used to fix the horizontal keel, the connection device only supports the horizontal keel inserted on the outside of the corner bracket. However, there will be waste residue that did not fall off during cutting between the inner wall of the horizontal keel and the upper wall of the corner bracket. After the other end is welded and the panel is installed, the weight of the panel will press down on the unwelded end of the horizontal keel, causing the unwelded end of the horizontal keel to squeeze the waste residue between the horizontal keel and the corner bracket. The unwelded end of the horizontal keel will tilt downward, resulting in tearing at the welded end of the horizontal keel, which affects the welding strength of the horizontal keel. Summary of the Invention

[0005] This application proposes an intelligent building curtain wall installation connection device and control method, which has the advantage of preventing the unwelded end of the horizontal keel from sinking, and solves the problem that there is waste residue between the unwelded end of the horizontal keel and the corner bracket, and the horizontal keel sinks due to being pressed down by the panel.

[0006] To achieve the above objectives, this application adopts the following technical solution: an intelligent building curtain wall installation and connection device and control method, comprising a main body, a locking block, a moving bar, and a support rod. The main body is provided with a telescopic groove, a pressing block, and a spiral rod. A liquid tank is formed inside the main body. The bottom end of the support rod passes through the upper end of the main body and extends into the liquid tank. A spiral groove is formed at the bottom end of the support rod. The liquid tank is provided with: a rotating rod, both ends of which are movably inserted into the inner wall of the liquid tank; external teeth I, arrayed and installed on the side wall of the rotating rod; a rack, the side wall of the liquid tank has a sliding groove, the rack is slidably installed in the sliding groove, and the rack meshes with external teeth I; two spiral tension shafts, the upper ends of which are threadedly connected to the spiral groove, and the lower ends are inserted into the main body; external teeth II, arrayed and installed on the outside of the spiral tension shafts, the external teeth II on one spiral tension shaft mesh with one of the racks, and the external teeth II on the other spiral tension shaft mesh with the other rack.

[0007] Furthermore, the top end of the rotating rod extends above the upper surface of the main body, and a hexagonal head is fixedly installed on the top end of the rotating rod.

[0008] Furthermore, a limit ring is fixedly connected to the outer side of one end of the spiral tension shaft extending into the main body.

[0009] Furthermore, a connecting hole is provided inside the support rod, the bottom end of the connecting hole is connected to the liquid tank, a comparison block is slidably and sealed inside the connecting hole, and the liquid tank and the connecting hole at the bottom end of the comparison block are filled with transmission fluid.

[0010] Furthermore, an observation groove is provided on the side wall of one side of the connecting hole, the observation groove is connected to the connecting hole, and an observation glass is fixedly installed in the observation groove.

[0011] Furthermore, the top ends of the two connecting holes are connected by a connecting pipe, and a prompting pipe is fixedly installed above the middle position of the connecting pipe. The bottom end of the prompting pipe is connected to the connecting pipe. The prompting pipe is equipped with: a support spring, the top end of which is fixedly connected to the inner wall of the prompting pipe; and a prompting block, which is fixedly connected to the bottom end of the support spring and is slidably sealed inside the prompting pipe. The prompting pipe and the connecting pipe at the lower end of the prompting block are filled with transmission fluid.

[0012] Furthermore, a through hole is provided at the center of the top of the indicator tube.

[0013] Furthermore, the diameter of the connection point between the prompting tube and the connecting tube is smaller than the inner diameter of the prompting tube.

[0014] Furthermore, the following steps are included:

[0015] S1. The horizontal keel is clamped in the slot of the support rod. One end of the horizontal keel is inserted into the corner bracket of the vertical keel on one side. The rotating rod and the external tooth I are rotated. Through the rack and pinion transmission, the external tooth II and the spiral tension shaft are rotated, which causes the spiral tension shaft to pull the support rod down. The slot of the lowered support rod pulls the horizontal keel, thus simulating that a panel is installed on the horizontal keel, so that the downward pull squeezes the waste between the horizontal keel and the corner bracket.

[0016] S2. When the support rod moves into the liquid tank, the support rod squeezes the transmission fluid in the liquid tank, causing some of the transmission fluid in the liquid tank to squeeze the comparison block through the connecting hole, thereby causing the comparison blocks in the connecting holes on both sides to move upward. The position of the upward-moving comparison blocks on both sides is indicated to the worker through the observation glass to indicate whether the horizontal keel is level.

[0017] S3. When the transmission fluid in the liquid tank enters the connecting hole and pushes the comparison block to move upward, the upward-moving comparison block pushes the transmission fluid at the top of the comparison block to enter the indicator tube through the connecting pipe, so that the transmission fluid in the indicator tube pushes the indicator block to move upward. After the indicator block moves to a certain position, it indicates that the compressive force on the support spring has reached the limit size, and the tension of the support rod on the horizontal keel has reached the limit size.

[0018] This application has the following beneficial effects:

[0019] 1. The intelligent building curtain wall installation and connection device provided in this application, by rotating the rotating rod, causes the external tooth I on the rotating rod to drive the rack, thereby driving the external tooth II and the spiral tension shaft to rotate. The rotating spiral tension shaft drives the support rod to move downward, so that the support rod pulls down on the horizontal keel, thereby simulating that a panel is installed on the horizontal keel. The downward force squeezes the waste between the horizontal keel and the corner bracket, preventing the unwelded end of the horizontal keel from being pressed down by gravity after the other end of the horizontal keel is welded, which would cause the welded end of the horizontal keel to tear.

[0020] 2. The intelligent building curtain wall installation and connection device provided in this application, when the horizontal keel is moved down by the support rod, the lower end of the support rod enters the liquid tank and squeezes the transmission fluid in the liquid tank, so that the transmission fluid in the liquid tank pushes the comparison block through the connecting hole, thereby moving the comparison block up. The comparison blocks on both sides move up and then prompt the workers through the observation glass. The horizontal keel is only in a horizontal state when the observation glass on both sides reaches the same position in the longitudinal direction of the horizontal keel.

[0021] 3. The intelligent building curtain wall installation and connection device provided in this application, when the comparison block in the connecting hole moves upward, the upward moving comparison block pushes the transmission fluid above, so that the transmission fluid enters the indicator tube through the connecting pipe, thereby squeezing the indicator block until the indicator block is squeezed to the designated position, thereby judging that the downward force of the support rod on the horizontal keel has reached the designated size, preventing the horizontal keel from being pulled by the large downward force of the support rod, which would cause the horizontal keel to bend.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 , Figure 2 and Figure 4 A smart building curtain wall installation and connection device includes a main body 1, a locking block 2, a moving strip 21, and a support rod 3. The main body 1 has a horizontally connected telescopic groove 11. A pressing block 12 is slidably installed in the middle of the telescopic groove 11, and a spiral rod 13 passes through the middle of the pressing block 12. The spiral rod 13 is threadedly connected to the pressing block 12. Both ends of the spiral rod 13 are movably inserted into the side wall of the telescopic groove 11. One end of the spiral rod 13 passes through the main body 1 and extends to the outside of the main body 1. The moving strip 21 is slidably installed in the telescopic groove 11 at both ends of the pressing block 12. The moving strip 21 is in close contact with the pressing block 12. The contact surface between the moving strip 21 and the pressing block 12 is an inclined surface, and the inclined surface of the moving strip 21 is parallel to that of the pressing block 12. The other end of the moving strip 21 extends out of the telescopic groove 11 and is fixedly connected to the locking block 2. The upper surface of the main body 1 is symmetrically provided with support rods 3 at both ends. The support rods 3 are used to support the horizontal keel 7.

[0035] Please see Figures 1-7 A horizontally arranged liquid tank 14 is provided inside the main body 1 on the upper side of the telescopic groove 11. The bottom end of the support rod 3 passes through the upper end of the main body 1 and extends into the liquid tank 14. The side wall of the support rod 3 is slidably sealed to the through point of the main body 1. A vertical rotating rod 15 is provided in the middle of the liquid tank 14. The two ends of the rotating rod 15 are movably inserted into the inner wall of the liquid tank 14. The top end of the rotating rod 15 extends above the upper surface of the main body 1. A hexagonal head is fixedly installed on the top end of the rotating rod 15 to facilitate the rotation of the rotating rod 15. External teeth I16 are installed in a circular array on the side wall of the rotating rod 15 inside the liquid tank 14. Sliding grooves are provided on the side walls on both sides of the liquid tank 14. Teeth are slidably installed in the sliding grooves. The support rod 3 has a helical groove 31 at its bottom end, and a helical tension shaft 18 is internally threaded into the helical groove 31. The lower end of the helical tension shaft 18 extends into the main body 1 below the support rod 3, and a limit ring is fixedly connected to the outer side of one end of the helical tension shaft 18 extending into the main body 1. The limit ring limits the helical tension shaft 18 to prevent it from moving upward. External teeth II 19 are installed in a ring array on the outer side of the helical tension shaft 18 in the liquid tank 14. The external teeth II 19 on one side of the helical tension shaft 18 mesh with one of the racks 17, and the external teeth II 19 on the other side of the helical tension shaft 18 mesh with another rack 17.

[0036] When fixing the horizontal keel 7, the locking blocks 2 on both sides of the main body 1 are engaged with the vertical keel 6. By twisting the spiral rod 13, the thread of the spiral rod 13 pushes the pressing block 12 to move, thereby causing the pressing block 12 to push the moving strips 21 and locking blocks 2 on both sides, so that the locking blocks 2 on both sides are tightly attached to the outer wall of the vertical keel 6, thereby fixing the device. Then, the horizontal keel 7 is engaged in the slot of the support rod 3. At the same time, one end of the horizontal keel 7 is inserted into the corner bracket of one side of the vertical keel 6. At this time, by rotating the rotating rod 15, the rotating rod 15 drives the external gear I 16 to rotate synchronously. This causes the external gear I16 to push the rack 17 to move. The moving rack 17 drives the external gear II19 and the spiral tension shaft 18 to rotate. Since the upper end of the spiral tension shaft 18 is threadedly connected to the spiral groove 31 of the support rod 3, the spiral tension shaft 18 pulls the support rod 3 downward. The downward movement of the support rod 3 pulls the horizontal keel 7 at the slot, thus simulating that a panel is installed on the horizontal keel 7. The downward pulling force squeezes the waste between the horizontal keel 7 and the corner bracket, preventing the unwelded end of the horizontal keel 7 from being pressed down by gravity after the other end of the horizontal keel 7 is welded, which would cause the welded end of the horizontal keel 7 to tear.

[0037] A connecting hole 32 is provided inside the support rod 3, and the bottom end of the connecting hole 32 is connected to the liquid tank 14. An observation groove 33 is provided on one side wall of the connecting hole 32, and the observation groove 33 is connected to the connecting hole 32. An observation glass 34 is fixedly installed in the observation groove 33 for observing the condition inside the connecting hole 32. A comparison block 35 is slidably and sealed inside the connecting hole 32 located on the lower side wall of the observation glass 34. The connecting hole 32 at the bottom end of the comparison block 35 in the liquid tank 14 is filled with transmission fluid. During the process of driving the support rod 3 to move into the liquid tank 14, the bottom end of the support rod 3 extends into the liquid tank 14, and the support rod 3 squeezes the transmission fluid in the liquid tank 14, causing some of the transmission fluid in the liquid tank 14 to enter the connecting hole 32. This causes the transmission fluid in the connecting hole 32 to squeeze the comparison block 35, causing the comparison blocks 35 in the connecting holes 32 on both sides to move upwards. The position of the upward-moving comparison blocks 35 on both sides is observed through the observation glass 34 to indicate to the worker whether the horizontal keel 7 is horizontal. The horizontal keel 7 is only horizontal when the comparison blocks 35 on both sides reach the same position on the observation glass 34. This prevents the entire device from tilting after the fixing block 2 is fixed when the main body 1 is tilted, which would cause the horizontal keel 7 on the support rod 3 to tilt. If the horizontal keel 7 on the main body 1 and the support rod 3 is tilted, the comparison blocks 35 in the connecting holes 32 on both sides will be at the same horizontal height due to the principle of the communicating vessel, and the comparison blocks 35 on both sides will not be in the same position on the two observation glasses 34, thus indicating to the worker.

[0038] The top of the connecting hole 32 on the support rod 3 passes through the upper end of the support rod 3. The tops of the two connecting holes 32 are connected by a connecting pipe 4. A prompting pipe 5 is fixedly installed above the middle position of the connecting pipe 4. The prompting pipe 5 is vertically set, and its bottom end is connected to the connecting pipe 4. A support spring 51 is fixedly connected to the top of the inner wall of the prompting pipe 5, and a prompting block 52 is fixedly connected to the bottom end of the support spring 51. The prompting block 52 is slidably and sealed inside the prompting pipe 5. The prompting pipe 5 and the connecting pipe 4 at the lower end of the prompting block 52 are filled with transmission fluid. A through hole is opened at the center of the top of the prompting pipe 5 to discharge the gas at the top of the prompting block 52. The diameter of the connection between the prompting pipe 5 and the connecting pipe 4 is smaller than the inner diameter of the prompting pipe 5 to prevent the prompting block 52 from entering the connecting pipe 4 from the connection between the prompting pipe 5 and the connecting pipe 4. When the transmission fluid enters the connecting hole 32 and pushes the comparison block 35 upward, the upward-moving comparison block 35 pushes the transmission fluid at the upper end of the comparison block 35 through the connecting pipe 4 into the indicator pipe 5, causing the transmission fluid in the indicator pipe 5 to push the indicator block 52 upward. The upward-moving indicator block 52 squeezes the support spring 51. After the indicator block 52 moves to a certain position, it indicates that the squeezing force on the support spring 51 has reached a certain level. At this time, due to the transmission of force by the transmission fluid, the squeezing force of the transmission fluid in the liquid tank 14 by the two side support rods 3 is equal to the squeezing force on the indicator block 52. Thus, it is determined that the downward movement of the support rod 3 exerts a pulling force on the horizontal keel 7, indicating that the pulling force of the support rod 3 on the horizontal keel 7 has reached a certain level. This prevents the pulling force of the support rod 3 on the horizontal keel 7 from continuing to increase, which would cause the horizontal keel 7 to bend due to the large downward pulling force of the support rod 3.

[0039] The working principle of this invention is as follows:

[0040] Please see Figures 1-8 When fixing the horizontal keel 7, the locking blocks 2 on both sides of the main body 1 are engaged with the vertical keel 6. By twisting the spiral rod 13, the thread of the spiral rod 13 pushes the pressing block 12 to move, thereby causing the pressing block 12 to push the moving strips 21 and locking blocks 2 on both sides, so that the locking blocks 2 on both sides are tightly attached to the outer wall of the vertical keel 6, thereby fixing the device. Then, the horizontal keel 7 is engaged in the slot of the support rod 3. At the same time, one end of the horizontal keel 7 is inserted into the corner bracket of one side of the vertical keel 6. At this time, by rotating the rotating rod 15, the rotating rod 15 drives the external gear I 16 to rotate synchronously. This causes the external gear I16 to push the rack 17 to move. The moving rack 17 drives the external gear II19 and the spiral tension shaft 18 to rotate. Since the upper end of the spiral tension shaft 18 is threadedly connected to the spiral groove 31 of the support rod 3, the spiral tension shaft 18 pulls the support rod 3 downward. The downward movement of the support rod 3 pulls the horizontal keel 7 at the slot, thus simulating that a panel is installed on the horizontal keel 7. The downward pulling force squeezes the waste between the horizontal keel 7 and the corner bracket, preventing the unwelded end of the horizontal keel 7 from being pressed down by gravity after the other end of the horizontal keel 7 is welded, which would cause the welded end of the horizontal keel 7 to tear.

[0041] During the movement of the drive support rod 3 into the liquid tank 14, the bottom end of the support rod 3 extends into the liquid tank 14, and the support rod 3 squeezes the transmission fluid in the liquid tank 14, causing some of the transmission fluid in the liquid tank 14 to enter the connecting hole 32. This causes the transmission fluid in the connecting hole 32 to squeeze the comparison block 35, causing the comparison blocks 35 in the connecting holes 32 on both sides to move upward. The position of the upward-moving comparison blocks 35 on both sides is observed through the observation glass 34 to indicate to the worker whether the horizontal keel 7 is horizontal. The horizontal keel 7 is only horizontal when the comparison blocks 35 on both sides reach the same position on the observation glass 34. This prevents the entire device from tilting after the fixing block 2 is fixed when the main body 1 is tilted, which would cause the horizontal keel 7 on the support rod 3 to tilt. If the main body 1 and the horizontal keel 7 on the support rod 3 are tilted, the comparison blocks 35 in the connecting holes 32 on both sides will be at the same horizontal height due to the principle of the communicating vessel, and the comparison blocks 35 on both sides will not be in the same position on the two observation glasses 34, thus indicating to the worker.

[0042] When the transmission fluid in the liquid tank 14 enters the connecting hole 32 and pushes the comparison block 35 upward, the upward-moving comparison block 35 pushes the transmission fluid at the upper end of the comparison block 35 through the connecting pipe 4 into the indicator pipe 5, causing the transmission fluid in the indicator pipe 5 to push the indicator block 52 upward. The upward-moving indicator block 52 squeezes the support spring 51. After the indicator block 52 moves to a certain position, it indicates that the squeezing force on the support spring 51 has reached a limited size. At this time, due to the transmission of force by the transmission fluid, the squeezing force of the two side support rods 3 on the transmission fluid in the liquid tank 14 is equal to the squeezing force on the indicator block 52. Thus, it is determined that the downward pulling force of the support rod 3 on the horizontal keel 7 has reached a limited size, preventing the pulling force of the support rod 3 on the horizontal keel 7 from continuing to increase, which would cause the horizontal keel 7 to bend due to the large downward pulling force of the support rod 3.

[0043] The control method for intelligent building curtain wall installation and connection devices includes the following steps:

[0044] S1. When fixing the horizontal keel 7, the locking blocks 2 on both sides of the main body 1 are locked onto the vertical keel 6. By twisting the spiral rod 13, the thread of the spiral rod 13 pushes the pressing block 12 to move, thereby pushing the moving strips 21 and locking blocks 2 on both sides, so that the locking blocks 2 on both sides are tightly attached to the outer wall of the vertical keel 6, thereby fixing the device.

[0045] S2. The horizontal keel 7 is clamped in the slot of the support rod 3. One end of the horizontal keel 7 is inserted into the corner bracket of the vertical keel 6 on one side. The rotating rod 15 and the external tooth I 16 are rotated. The external tooth II 19 and the spiral tension shaft 18 are rotated through the rack 17. The spiral tension shaft 18 pulls the support rod 3 down. The slot of the lowered support rod 3 pulls the horizontal keel 7, thereby simulating that a panel is installed on the horizontal keel 7. The downward force squeezes the waste between the horizontal keel 7 and the corner bracket.

[0046] S3. When the support rod 3 moves into the liquid tank 14, the support rod 3 squeezes the transmission fluid in the liquid tank 14, causing some of the transmission fluid in the liquid tank 14 to squeeze the comparison block 35 through the connecting hole 32, thereby causing the comparison block 35 in the connecting holes 32 on both sides to move upward. The position of the upward-moving comparison block 35 on both sides is indicated to the worker through the observation glass 34 to indicate whether the horizontal keel 7 is horizontal.

[0047] When the transmission fluid in the liquid tank 14 enters the connecting hole 32 and pushes the comparison block 35 upward, the upward-moving comparison block 35 pushes the transmission fluid at the upper end of the comparison block 35 through the connecting pipe 4 into the indicator pipe 5, causing the transmission fluid in the indicator pipe 5 to push the indicator block 52 upward. After the indicator block 52 moves to a certain position, it indicates that the compressive force on the support spring 51 has reached a limited size, and the downward force of the support rod 3 on the horizontal keel 7 has reached a limited size.
