Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to an elevator door machine with an anti-pick-proof function and an anti-pick-proof method thereof. Background Art

[0002] The elevator door machine is a mechanism responsible for opening and closing the elevator hall car door. When it receives the elevator door opening and closing signals, the elevator door machine controls the door opening motor through its own control system, converts the torque generated by the motor into a force in a specific direction, and closes or opens the door. When the closing force is greater than 150N, the door machine automatically stops closing the door and opens the door in the opposite direction, which plays a certain role in door closing protection; the anti-pick device is a device that prevents passengers from prying open the elevator door when the elevator is running or the elevator fails, to prevent passengers from prying open the car door and falling off the elevator or getting stuck at the elevator exit; however, existing anti-pick devices all require the installation of external power, which is relatively wasteful. Summary of the invention

[0003] The object of the present invention is to provide an elevator door machine with an anti-pick function and an anti-pick method thereof, so as to solve the problem that the existing anti-pick door devices all need to be installed with external power, which is relatively wasteful.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an elevator door machine with an anti-pickpocket function, comprising an upper mechanical frame and a revolving belt located inside the upper mechanical frame, the revolving belt comprising an upper layer and a lower layer, elevator door moving blocks are symmetrically fixed on the upper layer and the lower layer, a ratchet body is rotatably installed on the upper part of the elevator door moving block, a ratchet bar meshing with the ratchet body is installed inside the upper mechanical frame, each ratchet bar is half the length of the upper layer, a rotating shaft is rotatably installed inside the upper mechanical frame near the upper layer and the middle part above the lower layer, a ratchet stop hook is fixed on the front end of the rotating shaft, an elastic pull rope is fixed between the rotating shaft above the upper layer and the lower layer, and an elastic pull rope is fixed between the rotating shaft above the lower layer and the upper layer.

[0005] Preferably, a connecting rod is installed below the elevator door moving block, and the lower end of each connecting rod is fixedly connected to the elevator door.

[0006] Preferably, a transverse slideway is provided on the lower side of the upper mechanical frame, and the connecting rod slides inside the slideway.

[0007] Preferably, a connecting hook is installed on the rotating shaft, one end of the elastic pull rope is fixedly connected to the connecting hook, and the elastic pull rope can pull the connecting hook to drive the rotating shaft to rotate.

[0008] Preferably, a groove is provided on the upper surface of the elevator door moving block, and the ratchet body is rotatably installed inside the groove.

[0009] A method for preventing pickpocketing of an elevator door machine with an anti-pickpocketing function comprises the following steps:

[0010] S1: When the rotary belt rotates, the rotary belt can drive the elevator door moving blocks to move relative to or towards each other, so as to open or close the two elevator doors;

[0011] S2: During the opening process, the ratchet body moves along the ratchet bar, and the upper and lower layers pull the corresponding elastic pull ropes, so that the elastic pull ropes rotate the shaft through the connecting hooks. When the shaft rotates, the ratchet stop hook can be driven to rotate, and then the ratchet stop hook is separated from the ratchet body, so that the ratchet body can continue to move along the ratchet bar while rotating, and the elevator door can be opened smoothly;

[0012] S3: When the elevator fails, the elevator door is in a closed state. At this time, the elastic pull rope does not generate tension on the rotating shaft. The ratchet hook is stuck on the ratchet body due to its own weight, limiting the ratchet body and preventing the ratchet body from rotating. When it cannot rotate, the ratchet bar can limit the movement of the ratchet body, thereby limiting the movement of the elevator door and avoiding the door being pulled;

[0013] S4: A knob is set on the outside of the elevator to control the rotation of the shaft. When the elevator door needs to be pried open from the outside, the ratchet hook is separated from the ratchet body by rotating the knob, and the door can be pried open from the outside.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: a ratchet is arranged on the elevator door moving block, a ratchet bar and a ratchet hook are arranged inside the mechanical frame; when the elevator door is opened or closed, the rotary belt itself can pull the pull rope, and the pull rope can pull the ratchet hook away from the ratchet body, and the ratchet body can rotate while moving along the ratchet bar to realize the opening and closing of the elevator door; when the elevator door is in a closed state, the ratchet hook blocks the rotation of the ratchet body, and then the ratchet bar can block the movement of the ratchet body, ultimately preventing the elevator door from being pried open; the device uses the rotary belt to pull the pull rope, does not require external power to pull, and is more economical.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 As shown, in the embodiment of the present invention, an elevator door machine with an anti-pickpocket function and an anti-pickpocket method thereof include an upper mechanical frame 2 and a rotary belt 3 located inside the upper mechanical frame 2, the rotary belt 3 includes an upper layer 31 and a lower layer 32, and elevator door moving blocks 5 are symmetrically fixed on the upper layer 31 and the lower layer 32. When the rotary belt 3 rotates, the elevator door moving blocks 5 can be driven to move relative or toward each other. Connecting rods 4 are installed below the elevator door moving blocks 5, and the lower end of each connecting rod 4 is fixed to the elevator door 1, so that the elevator door moving blocks 5 can drive the elevator door 1 to open or close through the connecting rod 4.

[0022] Combination Figure 1 In order to facilitate the stable movement of the connecting rod 4, a transverse slideway is opened on the lower side of the upper mechanical frame 2, and the connecting rod 4 slides inside the slideway.

[0023] Combination Figure 1 , Figure 2 and Figure 3 As shown, a ratchet body 8 is rotatably installed on the upper part of the elevator door moving block 5, and a ratchet bar 6 meshing with the ratchet body 8 is installed inside the upper mechanical frame 2. The length of each ratchet bar 6 is half of the upper layer 31, that is, during the movement of the elevator door moving block 5, the ratchet body 8 can move along the ratchet bar 6 and rotate at the same time.

[0024] Combination Figure 2 and Figure 3As shown, a rotating shaft 9 is rotatably installed in the middle of the upper layer 31 and the upper part of the lower layer 32 inside the upper mechanical frame 2, a ratchet stop hook 10 is fixedly connected to the front end of the rotating shaft 9, an elastic pull rope 7 is fixedly connected between the rotating shaft 9 above the upper layer 31 and the lower layer 32, and an elastic pull rope 7 is fixedly connected between the rotating shaft 9 above the lower layer 32 and the upper layer 31. That is, when the rotary belt 3 rotates, the upper layer 31 and the lower layer 32 can pull the corresponding elastic pull rope 7 respectively, so that the elastic pull rope 7 pulls the rotating shaft 9 to rotate, so that the rotating shaft 9 drives the ratchet stop hook 10 to rotate. Figure 2 and Figure 3 In the perspective shown, when the elastic pull rope 7 pulls the rotating shaft 9, the ratchet hook 10 is pulled away from the ratchet body 8. When the elevator door 1 is closed, the ratchet hook 10 returns to the original position due to its own weight. Figure 2 In the state shown, the ratchet body 8 is limited to prevent the ratchet body 8 from rotating. When it cannot rotate, the ratchet bar 6 can limit the movement of the ratchet body 8, thereby limiting the movement of the elevator door 1 to avoid the door being pried open.

[0025] In order to avoid the situation that the rescue personnel cannot pry open the elevator door from the outside, a knob can be set outside the elevator to control the rotation of the shaft 9. When the elevator door 1 needs to be pried open from the outside, the ratchet hook 10 is disengaged from the ratchet body 8 by rotating the knob, and the door can be pried open from the outside.

[0026] Combination Figure 2 and Figure 3 In order to facilitate the elastic pull rope 7 to pull the rotating shaft 9 to rotate, a connecting hook 11 is installed on the rotating shaft 9, one end of the elastic pull rope 7 is fixedly connected to the connecting hook 11, and the elastic pull rope 7 can pull the connecting hook 11 to drive the rotating shaft 9 to rotate;

[0027] like Figure 2 In order to save space, a groove is provided on the upper surface of the elevator door moving block 5, and the ratchet body 8 is rotatably installed inside the groove.

[0028] A method for preventing pickpocketing of an elevator door machine with an anti-pickpocketing function comprises the following steps:

[0029] S1: When the rotary belt 3 rotates, the rotary belt can drive the elevator door moving block 5 to move relative to or towards each other, so as to realize the opening or closing of the two elevator doors 1;

[0030] S2: During the opening process, the ratchet body 8 moves along the ratchet bar, and the upper layer 31 and the lower layer 32 pull the corresponding elastic pull rope 7, so that the elastic pull rope 7 rotates the rotating shaft 9 through the connecting hook 11. When the rotating shaft 9 rotates, the ratchet stop hook 10 can be driven to rotate, and then the ratchet stop hook 10 is separated from the ratchet body 8, so that the ratchet body 8 can continue to move along the ratchet bar 6 while rotating, and the elevator door 1 can be opened smoothly;

[0031] S3: When the elevator fails, the elevator door 1 is in a closed state. At this time, the elastic pull rope 7 does not generate tension on the rotating shaft 9. The ratchet hook 10 is stuck on the ratchet body 8 due to its own weight, limiting the ratchet body 8 and preventing the ratchet body 8 from rotating. When it cannot rotate, the ratchet bar 6 can limit the movement of the ratchet body 8, thereby limiting the movement of the elevator door 1 and avoiding the door being pulled;

[0032] S4: A knob is arranged outside the elevator to control the rotation of the shaft 9. When the elevator door 1 needs to be pried open from the outside, the ratchet hook 10 is disengaged from the ratchet body 8 by rotating the knob, and the door can be pried open from the outside.

[0033] Working principle and use process of the present invention: When the device is used, when the revolving belt 3 rotates, the revolving belt can drive the elevator door moving block 5 to move relative or toward each other, so as to realize the opening or closing of the two elevator doors 1. During the opening process, the ratchet body 8 moves along the ratchet bar, and the upper layer 31 and the lower layer 32 pull the corresponding elastic elastic pull rope 7, so that the elastic elastic pull rope 7 rotates the rotating shaft 9 through the connecting hook 11. When the rotating shaft 9 rotates, it can drive the ratchet stop hook 10 to rotate, thereby making the ratchet stop hook 10 disengage from the ratchet body 8, so that the ratchet body 8 can continue to move along the ratchet bar 6 while rotating, and the elevator door 1 can be opened smoothly;

[0034] When the elevator fails, the elevator door 1 is in a closed state. Figure 1 In the state shown, the elastic pull rope 7 does not generate tension on the rotating shaft 9, and the ratchet hook 10 is stuck on the ratchet body 8 due to its own weight, limiting the ratchet body 8 and preventing the ratchet body 8 from rotating. When it cannot rotate, the ratchet bar 6 can limit the movement of the ratchet body 8, thereby limiting the movement of the elevator door 1 and avoiding the door being pulled;

[0035] In order to avoid the situation where the rescuers cannot pry open the elevator door from the outside, a knob can be set outside the elevator to control the rotation of the shaft 9. When the elevator door 1 needs to be pried open from the outside, the ratchet hook 10 is disengaged from the ratchet body 8 by rotating the knob, and the door can be pried from the outside.

[0036] A ratchet is arranged on the elevator door moving block, and a ratchet bar and a ratchet hook are arranged inside the mechanical frame. When the elevator door is opened or closed, the rotary belt itself can pull the pull rope, and the pull rope can pull the ratchet hook away from the ratchet body, and the ratchet body can rotate while moving along the ratchet bar to realize the opening and closing of the elevator door. When the elevator door is in a closed state, the ratchet hook blocks the rotation of the ratchet body, and then the ratchet bar can block the movement of the ratchet body, ultimately preventing the elevator door from being pried open. The device uses the rotary belt to pull the pull rope, does not require external power to pull, and is more economical.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
