Description

Technical Field

[0001] The present application belongs to the technical field of electric rolling shutter doors, and in particular relates to a manual zipper drive device of a tubular high-speed motor. Background Art

[0002] When the motor of an existing electric rolling door is out of power, you need to activate manual mode, that is, manually operate the rolling door to open it. Because the brake device is installed at the brake position on the motor end, when manually opening it, you need to manually pull the operating lever and then use the hand crank to turn the motor shaft to open the rolling door.

[0003] During the above operation, the operator needs to be at the motor position. The motor position of a conventional fast rolling shutter door is more than 3 meters above the ground. At this time, the operator needs to stand at a height to work, and the working space is often limited. The operator needs to open the brake with one hand and drive the reel with the other hand. The operation is complicated and laborious.

[0004] Therefore, the current manual mode when the motor is out of power has the problems of high risk of high-altitude operation, high operating space requirements, and laborious operation. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a manual zipper driving device with a tubular fast motor in order to solve the problems of high risk of hollow operation, high operating space requirement, and laborious operation in the prior art.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] The hand chain drive device of the present invention is a manual zipper drive device of a tubular fast motor, comprising an outer hexagonal shaft of the motor installed on the outer output shaft of the tubular motor of a rolling shutter door, and also comprising a hand hoist bracket, a hand steel rope bracket, an elastic pin device, a manual hoist, a hand steel rope, a mounting bolt, and a manual crank mechanism. One end of the elastic pin device matches the outer hexagonal shaft of the motor and is inserted into the outside of the outer hexagonal shaft of the motor. The hand hoist bracket is fixed to the corresponding position of the outer hexagonal shaft of the motor by the mounting bolt. The manual hoist is installed on the outer end of the hand hoist bracket. The manual hoist and the hand hoist bracket are both provided with a movable hole for accommodating the elastic pin device. The hand steel rope bracket is installed on the outer end of the manual hoist. A jack is provided on the manual hoist and at a position corresponding to the position of the movable hole. The hand steel rope passes through the jack and is movably connected to one end of the elastic pin device. Pulling the hand steel rope drives the elastic pin device to move in the movable hole, limiting the elastic pin device from being inserted into or not being inserted into the outer hexagonal shaft of the motor. The end of the pulled hand steel rope is located at the manual crank mechanism, and the hand steel rope is wound or unwound by the manual crank mechanism.

[0008] Furthermore, the elastic pin device includes a sleeve, a limit sleeve, a spring, and a hanging buckle. The limit sleeve and the spring sleeve are arranged outside the sleeve. The hanging buckle is arranged at one end of the sleeve close to the spring. The hand-pulled steel rope is pulled through the hanging buckle and then through the socket. The other end of the sleeve is connected to the external hexagonal shaft of the motor. The outer diameter of the limit sleeve is larger than the diameter of the movable hole of the hand hoist bracket. One end of the spring is fixed on the limit sleeve, and the other end is fixed on the hand hoist bracket.

[0009] Furthermore, the supporting space in the hand chain hoist bracket can accommodate the limiting sleeve and the spring.

[0010] Furthermore, the hand-pull steel rope bracket is cross-shaped, and the jack is located at the center of the hand-pull steel rope bracket.

[0011] Furthermore, nuts are provided on both sides of the hand-pull steel rope bracket, bolts are connected to the inner threads of the nuts, and holes are opened in the bolts to allow the hand-pull steel rope to pass through.

[0012] Furthermore, the hand pull rope is replaced by a hand throttle cable.

[0013] The beneficial effects of the utility model are:

[0014] 1. This utility model can be operated while standing on the ground, which is highly flexible, safer and more labor-saving;

[0015] 2. The structural design of the utility model product occupies a small space. The utility model product adopts structures such as hand-pull steel rope bracket and elastic pin device, which is easy and quick to install, reduces labor intensity and installation labor cost, and indirectly reduces construction risks.

[0028] Example

[0029] The present embodiment provides a manual zipper drive device for a tubular fast motor, including an outer hexagonal shaft of the motor installed on the outer output shaft of the tubular motor of the rolling door, and also includes a hand hoist bracket 1, a hand steel rope bracket 2, an elastic pin device 3, a manual hoist 4, a hand steel rope 5, a mounting bolt 6, and a manual crank mechanism 7. One end of the elastic pin device 3 matches the outer hexagonal shaft of the motor and is inserted into the outside of the outer hexagonal shaft of the motor. The hand hoist bracket 1 is fixed to the corresponding position of the outer hexagonal shaft of the motor by the mounting bolt 6. The manual hoist 4 is installed on the outer end of the hand hoist bracket 1. The manual hoist 4 and the hand hoist bracket 1 are both provided with a movable hole 8 to accommodate the elastic pin device 3. The pulling steel rope bracket 2 is installed on the outer end of the manual hoist 4, and a socket 9 is provided on the manual hoist 4 at a position corresponding to the movable hole 8. The hand-pulling steel rope 5 passes through the socket 9 and is movably connected to one end of the elastic pin device 3. Pulling the hand-pulling steel rope 5 drives the elastic pin device 3 to move in the movable hole 8, limiting whether the elastic pin device 3 is inserted into the outer hexagonal shaft of the motor. The end of the pulling hand-pulling steel rope 5 is located at the manual crank mechanism 7, which rewinds or unwinds the pulling hand-pulling steel rope 5. The manual crank mechanism 7 is installed in a place that is easy for people to touch when standing on the ground; that is, the present application modifies the original handbrake device to a place that is easy for people to touch.

[0030] The elastic pin device 3 includes a sleeve 3.1, a limit sleeve 3.2, a spring 3.3, and a hook 3.4. The limit sleeve 3.2 and the spring 3.3 are sleeved outside the sleeve 3.1. The hook 3.4 is set at one end of the sleeve 3.1 close to the spring 3.3. The other end of the sleeve 3.1 is sleeved on the outer hexagonal shaft of the motor. The outer diameter of the limit sleeve 3.2 is larger than the diameter of the movable hole 8 of the hand hoist bracket 1. One end of the spring 3.3 is fixed on the limit sleeve 3.2, and the other end is fixed on the hand hoist bracket 1. The hand pulling steel rope 5 is pulled through the hook 3.4 and then through the jack 9. The hand pulling steel rope 5 is pulled to tighten the part of the hand pulling steel rope 5 located in the hand hoist bracket 1, and then the sleeve 3.1 is pulled so that it is no longer sleeved into the outer hexagonal shaft of the motor. If the hand pulling steel rope 5 is not pulled, it is sleeved into the outer hexagonal shaft of the motor under the action of the elastic force of the spring.

[0031] The supporting space inside the hand chain hoist bracket 1 can accommodate the limit sleeve 3.2 and the spring 3.3. When the limit sleeve 3.2 is driven to contract, the sleeve 3.1, the limit sleeve 3.2 and the spring 3.3 are hidden in the supporting space. The hand pull steel rope bracket 2 is cross-shaped, and the socket 9 is located at the center of the hand pull steel rope bracket 2.

[0032] In order to reduce the wear of the hand-pull steel rope 5 and the hand-pull steel rope bracket 2, nuts 2.1 are provided on both sides of the hand-pull steel rope bracket 2. The inner thread of the nut 2.1 is connected to a bolt 2.2. The inner hole of the bolt 2.2 allows the hand-pull steel rope 5 to pass through. The bolt 2.2 plays a buffering role and increases the contact area, reducing wear and avoiding breakage.

[0033] As an embodiment of the present utility model, in addition to the above structure, the hand pull steel rope 5 is replaced by a hand throttle cable.

[0034] When using this utility model product:

[0035] Under normal circumstances, when the motor is running, the manual crank mechanism tightens the steel rope, so that the compression spring separates the motor shaft end and the pin shaft, which does not hinder the recommended operation of the motor;

[0036] When the motor is out of power or needs to be manually driven to rotate and you want to open the rolling door, shake the hand crank mechanism to loosen the hand pull rope and no longer tighten the elastic pin device. The sleeve rebounds and is ejected under the elastic force of the spring. Under the action of the spring thrust, the sleeve is easily inserted into the outer hexagonal shaft of the motor. Pull the hand chain hoist to see that the rolling door can be manually raised and lowered normally.

[0037] After use, stop pulling the manual crank handle mechanism, rewind one or two chain links, operate the manual crank handle mechanism to tighten the hand pull rope, and then compress the spring to disengage the motor shaft end (hexagonal shaft end) and the elastic pin device, so as to realize manual drive to open and close the rolling shutter door. It is convenient for personnel to operate at a height of 1200mm from the ground, and it saves more effort.

[0038] Based on the above-mentioned ideal embodiments of this application, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
