Description

Technical Field

[0001] This utility model relates to the field of traction device technology, and in particular to a traction device with manual rescue function. Background Technology

[0002] The traction system is a key component in elevators and other vertical transportation equipment. When the traction system is working, the motor in the traction machine is energized and drives the traction sheave to rotate via a gearbox. Due to the friction between the traction sheave and the wire rope, and the fact that the two ends of the wire rope are connected to the car and the counterweight respectively, the wire rope moves in a certain direction under the drive of the traction sheave, thereby causing relative movement between the car and the counterweight. When the car rises, the counterweight descends; when the car descends, the counterweight rises. Through this relative movement, the elevator achieves its passenger or freight transport function. Furthermore, the brake in the traction machine quickly brakes when the elevator stops, stopping the traction sheave and preventing accidental movement of the car and counterweight. In case of elevator malfunction, the brake engages the brake wheel when the elevator stops, keeping the elevator stationary and ensuring safety.

[0003] Modern traction systems typically include a manual handwheel, which is usually round and easy for operators to turn manually. Through its connection with the traction machine, the traction sheave can be manually turned in an emergency to move the car and bring the elevator to a safe position.

[0004] When implementing existing technical solutions, manually turning the manual handwheel to drive the traction wheel is very slow, and the rotation distance is also limited by manpower and ease of operation. It can only move the car a short distance and cannot move as quickly and over a wide area as during normal operation, which puts a great burden on manpower and the people waiting to be rescued. Summary of the Invention

[0005] The purpose of this utility model is to provide a traction device with manual rescue function, which can quickly and stably adjust the floor of the elevator car, avoiding the labor intensity and trouble of manual adjustment by staff, while improving the adjustment speed and the rescue speed of trapped people, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a traction device with manual rescue function, comprising a support frame, wherein the main body of the traction device is embedded inside the support frame, and a device shell is embedded at the front end of the support frame, wherein a handwheel is rotatably connected to the front end of the device shell, and an adjustment mechanism is provided below the device shell.

[0007] The adjustment mechanism includes a connecting frame, which is fixedly installed below the front end of the equipment housing of the support frame. A sliding groove is provided at the top of the connecting frame, and a bearing plate is slidably connected inside the sliding groove. A motor is embedded in the outer wall of the bearing plate. A drive rod is fixedly installed at the power output end of the motor, and a rotating rod is fixedly installed at the end of the drive rod away from the motor. A limit hole is provided on the inner wall of the handwheel corresponding to the position of the rotating rod.

[0008] Preferably, a mounting bracket is fixedly installed below the motor on the outer wall of the bearing plate, and a connecting rod is rotatably connected inside the mounting bracket.

[0009] Preferably, a sleeve is fitted around the outside of the connecting rod, and a support rod is fixedly installed at one end of the sleeve.

[0010] Preferably, the connecting rod is threadedly connected to the sleeve, and the sleeve and the support rod form a rotating structure.

[0011] Preferably, a positioning hole is provided on one side of the limiting hole on the outer wall of the handwheel, a fixing plate is fixedly installed on one side of the outer wall of the rotating rod, and a positioning rod is fixedly installed on the outer wall of the fixing plate at the position corresponding to the positioning hole.

[0012] Preferably, a manual mechanism is provided on the outside of the rotating rod. The manual mechanism includes a sleeve block, which is sleeved on one side of the outer wall fixing plate of the rotating rod, and a through groove is provided inside the sleeve block corresponding to the position of the rotating rod.

[0013] Preferably, a connecting plate is fixedly installed on the outer wall of the sleeve block, and a pressing rod is fixedly installed between the two connecting plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a motor to provide power, which enables the drive rod to drive the handwheel through the limit hole, thereby enabling the traction equipment body to work through the traction wheel. It can quickly and stably adjust the floor of the elevator car, avoiding the labor intensity and trouble of manual adjustment by staff, and at the same time, it can improve the adjustment speed and improve the rescue speed of trapped people.

[0016] 2. By limiting the rotating rod with the sleeve block and through slot, it can be manually supported after adjustment to prevent the traction sheave from becoming loose and causing the elevator car to shake. At the same time, the traction sheave can be adjusted to adjust the elevator car even in a completely power-off state. Compared with the handwheel adjustment method, it is more convenient for two staff members to adjust the output. Attached Figure Description

[0024] 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.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4A traction device with manual rescue function includes a support frame 1, a traction equipment body 2 embedded inside the support frame 1, an equipment shell 3 embedded at the front end of the support frame 1, a handwheel 4 rotatably connected to the front end of the equipment shell 3, and an adjustment mechanism 5 disposed below the equipment shell 3; the adjustment mechanism 5 includes a connecting frame 501, which is fixedly installed below the equipment shell 3 at the front end of the support frame 1; a sliding groove 502 is formed at the top end of the connecting frame 501, a bearing plate 503 is slidably connected inside the sliding groove 502, and a motor 504 is embedded in the outer wall of the bearing plate 503; the power transmission of the motor 504 is... A drive rod 505 is fixedly installed at the output end. A rotating rod 506 is fixedly installed at the end of the drive rod 505 away from the motor 504. A limit hole 507 is opened on the inner wall of the handwheel 4 corresponding to the position of the rotating rod 506. A mounting bracket 508 is fixedly installed on the outer wall of the bearing plate 503 below the motor 504. A connecting rod 509 is rotatably connected inside the mounting bracket 508. A sleeve 510 is sleeved on the outside of the connecting rod 509. A support rod 511 is fixedly installed at one end of the sleeve 510. The connecting rod 509 is threadedly connected to the sleeve 510. The sleeve 510 and the support rod 511 form a rotating structure.

[0027] By adopting the above technical solution, the connecting rod 509 is pushed by rotating the sleeve 510, and is kept stable by the rotation and locking of the support rod 511. The connecting rod 509 and the support rod 511 are rotatably connected to the bearing plate 503 and the connecting frame 501 respectively through the corresponding mounting bracket 508. This avoids the bearing plate 503 from being limited when sliding along the slide groove 502, which would prevent the position from being adjusted. During adjustment, the rotating rod 506 is inserted into the limiting hole 507 of the handwheel 4. Then, the motor 504 drives the drive rod 505 to drive the rotating rod 506 to drive the handwheel 4, thereby adjusting the handwheel 4. This ensures that the traction wheel of the traction equipment body 2 is adjusted stably and quickly, avoiding excessive workload on the staff or complicated operation, and quickly getting the elevator car to a safe floor, thus improving the rescue speed of trapped personnel.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, a positioning hole 6 is provided on one side of the limiting hole 507 on the outer wall of the handwheel 4. A fixing plate 7 is fixedly installed on one side of the outer wall of the rotating rod 506. A positioning rod 8 is fixedly installed on the outer wall of the fixing plate 7 at the position corresponding to the positioning hole 6. A manual mechanism 9 is provided on the outside of the rotating rod 506. The manual mechanism 9 includes a sleeve block 901. The sleeve block 901 is sleeved on one side of the fixing plate 7 on the outer wall of the rotating rod 506. A through groove 902 is provided inside the sleeve block 901 at the position corresponding to the rotating rod 506. A connecting plate 903 is fixedly installed on the outer wall of the sleeve block 901. A pressing rod 904 is fixedly installed between the two connecting plates 903.

[0029] By adopting the above technical solution, when the rotating rod 506 is inserted into the limiting hole 507, the positioning rod 8 fixed by the fixing plate 7 passes through the positioning hole 6, which further improves the stability of the connection and improves the torque stability and load-bearing capacity of the handwheel 4 during rotation. When the elevator reaches the safe floor, the manual hand-pressing rod 904 stabilizes the sleeve block 901 through the connecting plate 903, thereby limiting the rotating rod 506 through the through groove 902. This prevents the traction wheel from being affected by the weight of the elevator car after the motor 504 stops, causing the rotating rod 506 to rotate, which would lead to loosening and causing the elevator car to shake. At the same time, in the absence of power, the pressing rod 904 can be used to make the sleeve block 901 drive the rotating rod 506 to rotate. Compared with the manual rotation of the handwheel 4, it is easier for two people to adjust the output.

[0030] Working principle: The main body 2 of the traction equipment is fixedly supported by the support frame 1, and the equipment housing 3 is used to install the manual turning wheel, reduction gear set, etc. The traction sheave can be adjusted by rotating the handwheel 4 with a small force, thereby controlling the position of the elevator car. When adjustment of the traction sheave is required, after holding the handwheel 4, the brake is released to prevent the traction sheave from loosening. Rotating the sleeve 510 rotates the support rod 511, pushing the threaded connecting rod 509. Under the rotational support of the mounting frame 508, the bearing plate 503 slides along the slide groove 502 on the connecting frame 501, allowing the rotating rod 506 to insert into the limiting hole 507 of the handwheel 4. Driven by the motor 504, the drive rod 505 drives the rotating rod 506, thereby adjusting the traction sheave. When 507 and rotating rod 506 cannot be aligned, handwheel 4 can be manually adjusted to align them. The equipment used by motor 504 provides power to the on-site battery equipment to avoid incompatibility with the elevator system power supply. When rotating rod 506 is inserted into limit hole 507, positioning rod 8 of fixing plate 7 is inserted into positioning hole 6, further improving the pushing power of handwheel 4 and maintaining stable pushing. When the elevator car is adjusted to the appropriate position, manual support is required for pressing rod 904, which drives connecting plate 903 to position rotating rod 506 through through slot 902 via sleeve block 901. This prevents the drive rod 505 from loosening and rotating when motor 504 stops, which could cause instability in the elevator. Alternatively, in the absence of power, pressing rod 904 can be manually pressed to adjust the position of the elevator car.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
