Description

Technical Field

[0001] This utility model relates to the field of safety device technology, specifically an industrial door safety device. Background Technology

[0002] In industrial production and warehousing facilities, industrial doors serve as crucial separation and passage facilities, and their safety and reliability are of paramount importance. Traditional industrial door safety devices suffer from numerous problems, seriously affecting the normal use of industrial doors and the safety of personnel and equipment.

[0003] Traditional industrial doors lack effective support and positioning mechanisms during lifting and lowering. When lowering, if they encounter unexpected obstacles or are operated improperly, the door may suddenly plummet, causing serious damage to personnel and equipment below. Furthermore, during the lifting process, the lack of precise positioning control can easily lead to jamming or tilting, preventing the door from closing or opening properly and impacting production efficiency. Moreover, the drive system design of traditional industrial doors is inadequate. Many industrial doors use a simple direct motor drive, which generates significant inertial force during start-up and stop, easily causing the door to sway and increasing safety hazards. Simultaneously, the motor's power is often improperly matched, either failing to meet the door's lifting requirements, resulting in slow operation, or exceeding the required power, leading to energy waste and increased equipment cost and maintenance complexity.

[0004] Furthermore, traditional industrial door safety devices are structurally complex with numerous components, which not only increases the difficulty of manufacturing and installation but also raises the probability of malfunctions. Moreover, once a component fails, repair and replacement are cumbersome, requiring significant time and manpower, thus disrupting the normal operation of the industrial door. To address these issues, we propose an industrial door safety device. Utility Model Content

Detailed Implementation

[0019] 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 protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: an industrial door safety device, including a door frame 1, a traction group 2, a support device 3, a sliding positioning integrated device 4, a transmission device 5, a pulley group 6, a drive device 7, and a counterweight 8.

[0021] The gantry 1 serves as the support frame for the entire device. The top of the gantry 1 is connected to the pulley block 6. The gantry 1 includes two traction rails 11, a top mounting beam 12, and multiple support beams 13. The two traction rails 11 are placed opposite each other, and multiple support beams 13 are evenly arranged between them. The top mounting beam 12 is connected between the two traction rails 11 near the top, and the top mounting beam 12 is connected to the pulley block 6.

[0022] This structural design gives the gantry 1 sufficient strength and stability to withstand various forces during the lifting and lowering of the industrial door.

[0023] The traction assembly 2 is slidably connected to the gantry 1, and includes a traction frame 21 and a gate 22. The side of the traction frame 21 is connected to the pulley assembly 6 by a steel rope, and the top surface of the traction frame 21 is connected to the gate 22.

[0024] The traction group 2 slides up and down along the gantry 1 under the traction of the steel rope, thereby realizing the raising and lowering of the gate 22.

[0025] The support device 3 includes a web 31, a flange 32, and a rack 33. The two opposite sides of the web 31 are respectively connected to a flange 32, and the outer side of the flange 32 is connected to the rack 33.

[0026] The support device 3 moves under the drive of the sliding positioning integrated device 4 to provide support for the gate 22.

[0027] The sliding positioning integrated device 4 is disposed between the two traction rails 11 and close to the counterweight 8. This arrangement allows the support device 3 to move a longer distance toward the counterweight 8, preventing the support device 3 from reaching the position first and blocking the rise of the gate 22 when it is being raised.

[0028] The sliding positioning integrated device 4 includes a mounting top frame 41, a gear 42, a first track wheel 43, a first bearing seat 44, a mounting base 45, a second track wheel 46, and a second bearing seat 47. The mounting top frame 41 and the mounting base 45 are connected to the inner side of the gantry 1. The bottom surface of the mounting top frame 41 is connected to the first bearing seat 44. The first bearing seat 44 is connected to the first track wheel 43 and the gear 42 through a connecting shaft. The driving end of the driving device 7 is connected to the gear 42. The top surface of the mounting base 45 is connected to the second bearing seat 47. The second bearing seat 47 is rotatably connected to the second track wheel 46.

[0029] The top surface of the flange 32 of the support device 3 abuts against the first track wheel 43, and the bottom surface of the flange 32 abuts against the second track wheel 46. The rack 33 meshes with the gear 42, so that the support device 3 can slide stably within the sliding positioning integrated device 4, and achieve precise positioning control through the rotation of the gear 42.

[0030] Rubber pads are provided on the contact surfaces of the second track wheel 46 and the first track wheel 43 with the flange 32.

[0031] The transmission device 5 includes a first transmission wheel 51 and a second transmission wheel 52. The first transmission wheel 51 is connected to the pulley block 6 via a connecting shaft, and the second transmission wheel 52 is connected to the sliding positioning integrated device 4 via a connecting shaft. The first transmission wheel 51 is connected to the second transmission wheel 52 via a transmission chain. The diameter of the first transmission wheel 51 is smaller than the diameter of the second transmission wheel 52. This design enables the transmission of force and the conversion of speed, allowing the pulley block 6 and the sliding positioning integrated device 4 to work in coordination.

[0032] The pulley block 6 includes a main fixed pulley 61 and a secondary fixed pulley 62. The main fixed pulley 61 is connected to the top surface of the top mounting beam 12, and the secondary fixed pulley 62 is connected to the side surface of the top mounting beam 12. The main fixed pulley 61 is connected to one end of the transmission device 5 via a connecting shaft, and the other end of the transmission device 5 is connected to the sliding positioning integrated device 4. The pulley block 6 serves to change the direction of force and reduce force, enabling the traction group 2 to rise and fall smoothly.

[0033] The drive unit 7 is a three-phase asynchronous motor of model Y2-132M-4. This motor has the characteristics of moderate power, stable operation, and high efficiency, which can meet the power requirements of industrial door lifting. The side wall of the drive unit 7 is connected to the gantry 1, and the drive end of the drive unit 7 is connected to the gear 42 of the sliding positioning integrated device 4, providing power to the entire device.

[0034] The counterweight 8 is connected to the pulley block 6 via a steel rope. The weight of the counterweight 8 is the same as the weight of the traction block 2. Through the balancing effect of the counterweight 8, the industrial door is made more stable during the lifting and lowering process, reducing swaying. The sliding positioning integrated device 4 is located between the two traction rails 11 and close to the counterweight 8. This arrangement allows the support device 3 to move a longer distance toward the counterweight 8, preventing the support device 3 from reaching the position first and blocking the gate 22 from rising when the gate is raised.

[0035] Working principle: The initial state of this application is that the traction frame 21 is placed on top of the support device 3.

[0036] When the gate 22 needs to be lowered, the drive device 7 is activated. The drive device 7 drives the support device 3 to move to one side of the counterweight 8, and drives the pulley group 6 to rotate through the transmission device 5, so that the traction group 2 is lowered until the traction frame 21 contacts the bottom surface and then the drive device 7 is stopped.

[0037] When it is necessary to raise the gate 22, the drive device 7 is activated and reversed, driving the support device 3 to move towards the gate 22. When the traction frame 21 rises above the support device 3, the drive device 7 stops.
