Description

Technical Field

[0001] The invention relates to the technical field of rolling equipment, and in particular to a waterproof coiled material rolling safety warning device. Background Art

[0002] Waterproofing roll refers to a flexible waterproofing material product that can be rolled into a roll by impregnating asphalt or polymer waterproofing materials on the base. Its main function is to prevent the penetration of rainwater, groundwater and other moisture, and is used for moisture-proof, anti-seepage and anti-leakage of buildings and structures. It is widely used in the fields of construction, transportation, environmental protection, etc.

[0003] After the waterproof membrane is produced on the production line, it needs to be rolled into a roll by a rolling device for easy storage, transportation and subsequent use. The rolling device is composed of a conveying unit, a winding unit, a cutting unit and other parts.

[0004] The prior art has the following defects: Since most winding equipment still requires the assistance of staff, the reel will rotate at high speed when the winding unit reels the waterproof material. During this process, the staff may be careless or operate improperly, causing their clothes, hair, and limbs to be caught in the reel due to being too close to the reel. This may cause serious safety accidents. If the equipment is not shut down in time, it will cause serious harm to the staff.

[0005] Most winding equipment is equipped with an emergency stop switch. In the event of an emergency, the staff can hit the emergency stop switch to stop the reel immediately. Although this ensures work safety, due to the high speed and high torque of the reel and the heavy waterproof roll material wound on the outside, immediate braking in this state will cause greater damage to the reel, which is not conducive to the long-term and stable operation of the equipment. Summary of the invention

[0006] In view of the problem in the prior art that workers may be rolled up by the reel, a waterproof roll material rolling safety warning device is proposed.

[0007] The present application provides a waterproof coiled material curling safety warning device, the purpose of which is to improve the work safety of staff.

[0008] The technical solution of the present invention is: a waterproof coiled material curling safety warning device, including a board frame, an equipment cabinet arranged on the outer wall of the board frame, a machine table and a rotating shaft arranged on the inner wall of the board frame, a material unloading device arranged on the top of the machine table, and also includes sensing devices arranged on both sides of the machine table, the sensing device specifically includes an assembly slide groove opened on the outer surface of the machine table and the inner wall surface of the board frame, an assembly plate arranged inside the assembly slide groove, and a laser sensor arranged on the surface of the assembly plate; The assembly plate is slidably installed in the assembly slot, and the assembly plate extends out of the assembly slot. The laser sensor is divided into a laser receiver and a laser transmitter, which are respectively installed on the surfaces of the two assembly plates, and the positions of the laser receiver and the laser transmitter correspond to each other. A brake device is arranged on the outer side of the rotating shaft.

[0009] Furthermore, two assembly grooves are provided on the inner wall surface of the plate frame, which are respectively located at the two ends of the corresponding assembly panel, and one assembly groove is provided on the outer surface of the machine, which is located at the lower end of the corresponding assembly panel, and the top end of the assembly panel here extends upward, is bent ninety degrees, and then overlapped on the top of the plate frame.

[0010] Furthermore, an alarm is fixedly installed on the top of the equipment cabinet, and the alarm is connected to the receiver through an electrical signal line.

[0011] Furthermore, the rotating shaft is divided into a joint part and a winding part. The joint part is installed on the inner wall of the plate frame and extends into the equipment cabinet. The winding part is located above the machine platform and is sleeved on the outer side of the joint part.

[0012] Furthermore, the brake device specifically includes a shell cover arranged on the inner wall of the plate frame, an outer convex bin arranged on the outer side of the shell cover, an electric control telescopic rod arranged inside the outer convex bin, and a brake plate arranged at one end of the electric control telescopic rod close to the joint part; The shell cover is annularly sleeved on the outer side of the joint part, and the outer convex chamber is communicated with the shell cover.

[0013] Furthermore, the brake device also includes an inner connecting ring arranged on the outside of the joint part, an outer connecting ring arranged on the outside of the inner connecting ring, an inner connecting plate arranged on the outer wall of the inner connecting ring, an outer connecting plate arranged on the inner wall of the outer connecting ring, a buffer tube and a buffer plug rod arranged between the inner connecting plate and the outer connecting plate, fixed plug holes opened on the surfaces of the inner connecting plate and the outer connecting plate, and a buffer spring arranged inside the buffer tube; The inner connecting ring and the outer connecting ring are both located inside the shell cover, the buffer plug rod is slidably inserted into the buffer tube, the buffer plug rod is inserted into the fixed plug hole on the surface of the external connecting plate, and the buffer tube is inserted into the fixed plug hole on the surface of the internal connecting plate. The buffer plug rod and the buffer tube are both arc-shaped and are concentrically arranged with the joint part.

[0014] Furthermore, the inner connecting plate is attached to the inner wall of the outer connecting ring, and the outer connecting plate is attached to the outer wall of the inner connecting ring.

[0015] Furthermore, the outer side of the outer connecting ring and the side of the brake plate close to the outer connecting ring are both provided with teeth that mesh with each other.

[0016] Furthermore, the brake device also includes a bayonet opening on the outside of the buffer plug rod, an external connection platform arranged on the outside of the buffer tube, an external connection sleeve arranged on the inside of the external connection platform, and a push rod and a push spring arranged inside the external connection sleeve; The external connection platform is communicated with the buffer tube, the push rod passes through the buffer tube and is inserted into the bayonet, one end of the push spring is connected to the push rod, and the other end is connected to the inner wall of the external connection sleeve.

[0017] Furthermore, the laser sensor supports connection to Wi-Fi / Bluetooth.

[0018] Beneficial effects of the present invention: By setting an alarm, when working, the laser transmitter sends a laser signal to the laser receiver, and the laser receiver receives the signal and maintains normal operation. When a person or object approaches the rotating shaft, the laser signal is blocked and the laser receiver loses the signal, then the rotating shaft is stopped by the brake device. This can ensure the safety of the staff and avoid being caught in the high-speed rotating shaft. At the same time, the laser sensor can be moved through the assembly slide. In this way, the position of the laser sensor can be adjusted according to the diameter of the waterproof membrane to be processed, so that it always maintains a distance of five centimeters from the finished waterproof membrane. In this way, the laser sensor is as close to the rotating shaft as possible, which ensures safety while reducing the possibility of accidental touch, avoiding frequent braking of the rotating shaft and aggravating damage.

[0019] By connecting the laser transmitter and laser receiver to Wi-Fi / Bluetooth, remote control and alarm can be achieved. In case of emergencies, all equipment can be stopped remotely to avoid production accidents caused by unmanned equipment after the staff leave the site. The staff's violations can also be uploaded and recorded based on the feedback from the laser receiver for targeted training later.

[0020] 2. By setting a brake device, when braking, the external ring is first locked by the brake plate, and the external ring still rotates with the joint. During this process, the buffer rod compresses the buffer spring and inserts it into the buffer tube. The reaction force generated by the compression of the buffer spring is used to buffer and decelerate the joint head. The joint continues to rotate 90 degrees and then is completely braked. In this way, most of the impact force generated when the joint is braked can be removed, reducing the damage to the joint, which is beneficial to extending the service life of the equipment. At the same time, after braking, the joint can continue to rotate 90 degrees at most. Even if the body or objects are caught in the winding part, no harm will be caused.

[0021] 3. By further improving the braking equipment, the buffer rod and the buffer tube are locked by using the push rod and the bayonet. In this way, the buffer rod is supported by the buffer spring, so that the inner ring and the outer ring are more stable during the synchronous rotation. At the same time, after the equipment is braked, the buffer rod is inserted into the buffer tube and locked by the push rod. The accumulated force of the buffer spring compression will not be immediately released to push back the joint. The joint remains stationary, which can avoid secondary injuries to the staff.

[0026] By setting the alarm 7, when working, the laser transmitter sends a laser signal to the laser receiver, and the laser receiver receives the signal and keeps working normally. When a human body or an object approaches the rotating shaft 5, the laser signal is blocked and the laser receiver loses the signal, and the rotating shaft 5 is stopped by the brake device 8, so that the safety of the staff can be guaranteed and the staff can be prevented from being caught by the high-speed rotating shaft 5. At the same time, the laser sensor 63 can be moved through the assembly slide 61, so that the position of the laser sensor 63 can be adjusted according to the diameter of the waterproof membrane to be processed, so that it always keeps a distance of five centimeters from the finished waterproof membrane, so that the laser sensor 63 is as close to the rotating shaft 5 as possible, while ensuring safety, reducing the possibility of accidental touch, and avoiding frequent braking of the rotating shaft 5, which will increase the damage.

[0027] Specifically, two assembly grooves 61 are provided on the inner wall surface of the plate rack 1, which are respectively located at the two ends of the corresponding assembly panel 62, and one assembly groove 61 is provided on the outer surface of the machine table 3, which is located at the lower end of the corresponding assembly panel 62. Here, the top end of the assembly panel 62 extends upward, is bent ninety degrees, and overlaps the top of the plate rack 1. In this way, both ends of the assembly panel 62 have support points, which can maintain the stability of the movement of the assembly panel 62.

[0028] Specifically, an alarm 7 is fixedly installed on the top of the equipment cabinet 2. The alarm 7 is connected to the laser receiver through an electrical signal line. After the laser receiver loses the laser signal, the signal is transmitted to the alarm 7 through the electrical signal line, and the alarm 7 emits light and sound to alarm.

[0029] The rotating shaft 5 is divided into a joint portion 51 and a winding portion 52. The joint portion 51 is installed on the inner wall of the plate frame 1 and extends into the equipment cabinet 2, and is connected to the driving motor. The driving motor is connected to the laser receiver through an electrical signal line. The winding portion 52 is located above the machine table 3, and the winding portion 52 is sleeved on the outer side of the joint portion 51.

[0030] The brake device 8 specifically includes a shell cover 81 arranged on the inner wall of the plate frame 1, an outer convex chamber 82 arranged on the outer side of the shell cover 81, an electric control telescopic rod 83 arranged inside the outer convex chamber 82, and a brake plate 84 arranged at one end of the electric control telescopic rod 83 close to the joint part 51.

[0031] Specifically, the shell cover 81 is fixed to the inner wall of the plate frame 1 by bolts, the shell cover 81 is annularly sleeved on the outside of the joint part 51, the outer convex chamber 82 is connected to the shell cover 81, the electric control telescopic rod 83 is embedded in the outer convex chamber 82 and fixed by bolts, the electric control telescopic rod 83 is connected to the receiver through an electrical signal line, and the brake plate 84 is fixedly connected to the electric control telescopic rod 83.

[0032] Example 2, reference Figure 1-16, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the brake device 8 also includes an inner connecting ring 85 arranged on the outside of the joint part 51, an outer connecting ring 86 arranged on the outside of the inner connecting ring 85, an inner connecting plate 87 arranged on the outer wall of the inner connecting ring 85, an outer connecting plate 88 arranged on the inner wall of the outer connecting ring 86, a buffer tube 89 and a buffer plug rod 810 arranged between the inner connecting plate 87 and the outer connecting plate 88, a fixed socket 811 opened on the surface of the inner connecting plate 87 and the outer connecting plate 88, and a buffer spring 812 arranged inside the buffer tube 89.

[0033] Specifically, the inner connecting ring 85 is sleeved on the outer side of the joint part 51 and fixed by bolts, the outer connecting ring 86 is sleeved on the outer side of the inner connecting ring 85, the inner connecting plate 87 is welded to the inner connecting ring 85, the outer connecting plate 88 is welded to the outer connecting ring 86, the angle between the outer connecting plate 88 and the inner connecting plate 87 is one hundred and eighty degrees, the inner connecting ring 85 and the outer connecting ring 86 are both located inside the shell cover 81, the outer wall of the outer connecting ring 86 is fitted with the inner wall of the shell cover 81, the buffer plug rod 810 is slidably inserted into the buffer tube 89 and locked by bolts, the buffer plug rod 810 is inserted into the fixed socket 811 on the surface of the external plate 88 and locked by bolts, and the buffer tube 89 is inserted In the fixed socket 811 connected to the surface of the inner plate 87, the buffer rod 810 and the buffer tube 89 are both arc-shaped and concentrically arranged with the joint part 51. The supporting force provided by the buffer spring 812 for the buffer rod 810 is greater than the friction force exerted on the outer ring 86; the inner plate 87 is attached to the inner wall of the outer ring 86, and the outer plate 88 is attached to the outer wall of the inner ring 85, so that they support each other and can make the connection between the outer ring 86 and the inner ring 85 more stable; the outer side of the outer ring 86 and the side of the brake plate 84 close to the outer ring 86 are provided with teeth that mesh with each other, so as to enhance the friction between the two and enhance the braking effect.

[0034] By setting the brake device 8, when braking, the outer ring 86 is first locked by the brake plate 84, and the outer ring 86 still rotates with the joint part 51. During this process, the buffer rod 810 compresses the buffer spring 812 and is inserted into the buffer tube 89. The reaction force generated by the compression of the buffer spring 812 is used to buffer and decelerate the joint part 51. The joint part 51 continues to rotate ninety degrees and is completely braked. In this way, most of the impact force generated by the joint part 51 when braking can be removed, reducing the damage to the joint part 51, which is beneficial to extending the service life of the equipment. At the same time, after braking, the joint part 51 continues to rotate ninety degrees at most. Even if the body or objects are caught in the winding part 52, no harm will be caused.

[0035] The brake device 8 also includes a bayonet 813 opened on the outside of the buffer plug 810, an external platform 814 arranged on the outside of the buffer tube 89, an external sleeve 815 arranged on the inside of the external platform 814, and a push rod 816 and a push spring 817 arranged inside the external sleeve 815.

[0036] Specifically, the surface of the bayonet 813 and the buffer plug 810 are distributed in a circular array, the external platform 814 is connected to the buffer tube 89, the external sleeve 815 is connected to the external platform 814 by a threaded connection, the push rod 816 is slidably connected to the external sleeve 815, the push rod 816 passes through the buffer tube 89 and is inserted into the bayonet 813, and one end of the push rod 816 inserted into the bayonet 813 is hemispherical, one end of the push spring 817 is connected to the push rod 816, and the other end is connected to the inner wall of the external sleeve 815; suppose the force required to compress the buffer spring 812 is X, the force required to compress the push spring 817 is Y, and the force required to drive the external ring 86 to rotate is Z, and the relationship between the three is: X>Y>Z, Z+Y>X.

[0037] By further improving the braking device 8, the buffer rod 810 and the buffer tube 89 are locked by using the push rod 816 and the bayonet 813. In this way, the support of the buffer rod 810 by the buffer spring 812 makes the inner ring 85 and the outer ring 86 more stable during the synchronous rotation. At the same time, after the equipment is braked, the buffer rod 810 is inserted into the buffer tube 89 and locked by the push rod 816. The force accumulated by the compression of the buffer spring 812 will not be immediately released to push back the joint part 51. The joint part 51 remains stationary, which can avoid secondary injuries to the staff.

[0038] Based on Examples 1-2, the working principle of the waterproof coiled material curling safety warning device of the present invention is as follows: During installation, first insert the buffer spring 812 into the buffer tube 89, then insert the buffer rod 810 into the buffer tube 89, then screw the external sleeve 815 into the external platform 814, insert the push rod 816 into the buffer tube 89, and move the buffer rod 810 to insert the push rod 816 into the bayonet 813; sleeve the inner ring 85 on the outside of the joint part 51 and fix it with bolts, then insert the buffer tube 89 into the fixed socket 811 on the surface of the inner plate 87 and fix it with bolts, so that the buffer tube 89 and the buffer rod 810 are surrounded by the outside of the inner ring 85 , then sleeve the outer ring 86 on the outer side of the inner ring 85, make the inner plate 87 fit on the inner wall of the outer ring 86, and the outer plate 88 fit on the outer wall of the inner ring 85, rotate the outer ring 86, insert the buffer plug 810 into the fixed plug hole 811 on the surface of the external plate 88, and fix it with bolts; install the brake plate 84 on one end of the electric control telescopic rod 83, and then insert the electric control telescopic rod 83 into the outer convex chamber 82, fix it with bolts, and finally sleeve the shell cover 81 on the outer side of the inner ring 85 and the outer ring 86, and fix the shell cover 81 and the plate frame 1 with bolts.

[0039] Install the laser receiver and the laser transmitter on the surfaces of two assembly panels 62 respectively, and then install the two assembly panels 62 into the corresponding assembly slots 61 respectively. Adjust the distance from the laser sensor 63 to the rotating shaft 5 according to the diameter of the finished waterproof membrane to be processed. Slide the assembly panel 62 in the assembly slot 61 so that the minimum distance between the connecting line of the laser receiver and the laser transmitter and the outer surface of the finished waterproof membrane is five centimeters. Calibrate and debug the equipment so that the laser receiver can capture the laser signal of the laser transmitter.

[0040] When the device is wound, the joint part 51 drives the winding part 52 and the inner connecting ring 85 to rotate. The winding part 52 winds the waterproof material. At the same time, the inner connecting ring 85 pushes the buffer tube 89 to rotate through the inner connecting plate 87. The buffer tube 89 pushes the buffer plug 810 to rotate through the buffer spring 812. The buffer plug 810 pushes the outer connecting ring 86 to rotate through the outer connecting plate 88.

[0041] When an object approaches the rotating shaft 5 and blocks the laser signal emitted by the laser transmitter, the laser receiver loses the signal and sends a signal to the alarm 7 and the electric telescopic rod 83 through the electrical signal line. The alarm 7 receives the signal and emits light and sound to alarm. The electric telescopic rod 83 receives the signal and pushes the brake plate 84 close to the outer ring 86. The brake plate 84 presses on the surface of the outer ring 86 to lock it. The outer ring 86 stops rotating. The buffer rod 810 presses on the outer plate 88 and cannot move. The joint part 51 drives the inner ring 85 to continue rotating under the action of inertia. The inner ring 85 pushes the buffer tube 86 through the inner plate 87. 9. The buffer tube 89 and the buffer rod 810 make relative movement. The buffer rod 810 first pushes the push rod 816 out of the bayonet 813, and then compresses the buffer spring 812 and inserts it into the buffer tube 89. The buffer spring 812 contracts to absorb the power transmitted from the buffer tube 89, and removes the inertial force of the joint 51, thereby playing a buffering role. When the buffer rod 810 completely enters the buffer tube 89, most of the power of the joint 51 is removed, and the push rod 816 is inserted into the bayonet 813 at the corresponding position to lock the buffer rod 810 and the buffer tube 89. When the equipment needs to be restarted, the components are reset by rotating in the opposite direction.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
