The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] See also Figure 1 and Figure 2 , respectively disclose a structural schematic diagram of an embodiment of an elevator door blocking device of the utility model.

[0039] Figure 1 As shown, an elevator door blocking device, when the door blocking device 10 blocks the door, is installed in a door frame guide groove 1013 of a floor door 101, and contacts a floor door guide surface 1012 closer to the door frame guide groove 1013, preventing the floor door opening surface 101 from moving forward. The door blocking device includes a mounting portion 1 and a door blocking portion 2.

[0040] When blocking the door, the mounting portion 1 is installed in the door frame guide groove 1013, that is, the door blocking device 10 is installed at the layer plate position to achieve door blocking.

[0041] like Figure 1 The door blocking part 2 includes a door blocking wedge 21, and the door blocking wedge 21 has a door blocking inclined surface 22, and the door blocking inclined surface 22 has a lower end 23 and a higher end 24. When blocking the door, the door blocking inclined surface 22 is arranged toward the floor door opening surface 101, and the lower end 23 is inserted between the door frame guide groove 1013 and the floor door guide surface 1012, and the higher end 24 is arranged away from the floor door opening surface 101, and the higher end is higher than the floor door guide surface 1012.

[0042] The elevator door blocking device in the above embodiment, combined with the structure of the compartment elevator itself and its door opening and closing method, can be quickly and easily installed through the mounting portion 1 and the door frame guide groove 1013, and the floor door 101 is limited by the door blocking slope 22 on the door blocking wedge 21, so as to keep the floor door 101 in a certain open state, avoid the floor door 101 from being completely closed, and improve the safety during elevator maintenance.

[0043] The elevator door-blocking device in the above embodiment has a simple door-blocking wedge 21 structure. The door-blocking wedge 21 structure integrates the floor door 101 structure and its opening and closing method. The floor door guide surface 1012 contacts the door-blocking inclined surface 22 on the door-blocking wedge 21, so that the floor door is subjected to a certain clamping force on the door-blocking device, so that the door-blocking device is fixed in the door frame guide groove 1013 and the door is blocked.

[0044] In order to further ensure that the door-blocking device blocks the landing door and keeps the landing door in a relatively obvious open state, the overall length of the door-blocking device is extended. Figure 1 On the basis of the embodiment scheme, a door-blocking rod 3 is fixedly connected to the end face of the door-blocking wedge 21 away from the lower end 23. When blocking the door, the door-blocking rod 3 is parallel to the movement direction of the blocked floor door 101, and the distance between the door-blocking rod 3 and the door frame guide groove 1013 is greater than the distance between the floor door guide surface 1012 and the door frame guide groove 1013. The door-blocking device in this embodiment, when blocking the door, one end of the door-blocking device is placed below the floor door guide surface 1012, and the other end (the end of the door-blocking rod 3 away from the door-blocking wedge 21) is against the floor door frame or the floor door opening surface 101 of another floor door, so that the opening width of the floor door 101 is the overall length of the door-blocking device of the specific door-blocking rod 3, and the door-blocking device in this embodiment is more reliable because both ends of the door-blocking device are subjected to force, and the door-blocking device will not slide under the action of the blocked floor door.

[0045] Of course, the door-blocking device provided with a door-blocking rod can also be used as in the aforementioned embodiment when blocking the door. The end of the door-blocking rod 3 away from the door-blocking wedge 21 may not be against the door frame of the floor door or the floor door opening surface 101 of another floor door. The door blocking is achieved only by relying on the action between the door-blocking wedge, the door-blocking inclined surface and the floor door guide surface 1012, and the floor door can be stopped at any desired position.

[0046] In the above scheme, in order to ensure the opening width of the floor door and also avoid the floor door opening too wide, which may cause the problem of people falling on the floor slab, the length of the door blocking rod 3 is set to 15cm-25cm, the length of the door blocking rod is moderate, and the overall length of the door blocking device is moderate and reasonable. The door blocking device 10 will prevent the closing action of the floor door 101 to prevent the floor door from being completely closed, so that the floor door is in a certain open state, so that the elevator maintenance personnel can look into the elevator shaft through the floor door opening position, understand the working situation of the internal maintenance personnel, communicate with the maintenance personnel in the elevator shaft, improve the elevator maintenance efficiency, and observe the elevator shaft at the same time, and promptly discover or intervene in the working status of the maintenance personnel in the elevator shaft. In addition, by keeping the elevator floor door in a certain open state, people who want to take the elevator can promptly find that the elevator is in a maintenance state, avoid misoperation of the elevator during maintenance, and improve the safety factor of elevator maintenance.

[0047] The door-blocking wedge structure is not simplified, and the door-blocking wedge 21 is a wedge-shaped block with a triangular cross section. One side of the wedge-shaped block with a triangular cross section is fixedly connected to the mounting portion. The door-blocking wedge adopts a wedge-shaped block with a triangular cross section. On the one hand, the structure is simple, and the inclined surface is provided as the door-blocking inclined surface 22. On the other hand, the triangular door-blocking wedge has good strength and is reliable in blocking the door.

[0048] In order to further simplify the door-blocking wedge structure and facilitate the fixed installation of the door-blocking wedge and the mounting part, and after installation, the door-blocking device has a regular structure, the door-blocking wedge 21 is a wedge-shaped block with a right-angled triangle cross-section, and the inclined surface of the right-angled triangle wedge block is the door-blocking inclined surface 22.

[0049] like Figure 1 or Figure 2 The mounting portion 1 includes a rectangular mounting block 11. The width of the mounting block 11 is adapted to the width of the door frame guide groove 1013, so that the mounting block can be directly placed in the door frame guide groove 1013 and installed with the door frame guide groove 1013. The door-blocking wedge 21 is arranged on the side of the mounting block 11 away from the door frame guide groove 1013, so that it can contact with the floor door guide surface 1012 when blocking the door, and act on the floor door guide surface 1012 to achieve door blocking. The height of the mounting block 11 is less than the distance between the door frame guide groove 1013 and the floor door guide surface 1012. When blocking the door, the end face of the mounting block 11 close to the lower end 23 is inserted between the door frame guide groove 1013 and the floor door guide surface 1012, so that the floor door guide surface 1012 is pressed against the door-blocking inclined surface 22, so as to act on the door-blocking device and achieve door blocking.

[0050] like Figure 1 The length of the mounting block 11 is adapted to the door-blocking wedge 21, and the length of the door-blocking wedge 21 is 6 cm-10 cm. The distance between the high end 24 and the door frame guide groove 1013 is at least 2 cm greater than the distance between the floor door guide surface 1012 and the door frame guide groove 1013. The high end of the door-blocking inclined surface on the door-blocking wedge, on the one hand, enables the door-blocking inclined surface to block the floor door, thereby achieving door blocking. On the other hand, the high end of the door-blocking inclined surface on the door-blocking wedge is located outside the floor door when blocking the door, so the high end also serves as an operation control position of the door-blocking device when the door-blocking device is operated, thereby realizing operations such as taking and placing the door-blocking device, thereby ensuring the safe operation of the door-blocking device.

[0051] like Figure 2, the length of the mounting block 11 is greater than the length of the door-blocking wedge 21, and the end face of the mounting block 11 close to the lower end 23 extends out of the lower end 23; the length of the door-blocking wedge 21 is 6cm-10cm, and the length of the mounting block 11 is 0.5cm-2cm greater than the length of the door-blocking wedge 21. The distance between the high end 24 and the door frame guide groove 1013 is at least 2cm greater than the distance between the floor door guide surface 1012 and the door frame guide groove 1013. The length of the mounting block is greater than the length of the door-blocking wedge 21, so that when blocking the door, the end of the mounting block of the door-blocking device close to the lower end of the door-blocking inclined surface is placed under the floor door guide surface 1012, so as to protect the lower end of the door-blocking inclined surface and avoid the lower end of the door-blocking inclined surface from being collided and squeezed by the floor door guide surface 1012 and the floor door, resulting in cracking, curling and other problems. At the same time, the end of the mounting block of the door-blocking device close to the lower end of the door-blocking inclined surface is placed under the floor door guide surface 1012, ensuring that the overall force of the door-blocking device is uniform and extending the service life of the door-blocking device.

[0052] In order to improve the strength of the door-blocking device, avoid damage to the door-blocking device, and ensure the door-blocking ability and effect, the door-blocking wedge 21, the mounting block 11 and the door-blocking rod 3 are all made of high-strength plastic or high-strength metal material.

[0053] In order to simplify the molding conditions of the door-blocking device and reduce the manufacturing cost of the door-blocking device, the door-blocking wedge block 21, the mounting block 11 and the door-blocking rod 3 are integrally molded.

[0054] like Figure 5 and Figure 6 , is a diagram of the door blocking device in use, wherein the door blocking device 10 is used on a cabin elevator with doors opening to the left and right, the door blocking device is installed in a horizontal state, the mounting block is placed in a door frame guide groove 1013 in a horizontal state, the door blocking wedge faces the floor door opening surface 1011, and the floor door guide surface 1012 of the floor door 101 is pressed against the door blocking inclined surface, so that the door blocking device is fixed in the door frame guide groove 1013 and maintained at the desired door blocking position, preventing the floor door from continuing to close and ensuring that the floor door is in a certain open state. Figure 5 and Figure 6 The door blocking device shown in FIG. 1 is installed in the door frame guide groove 1013 on the floor of the floor door, and the door blocking device can also be installed in the door frame guide groove 1013 on the ceiling of the floor door. Its working principle and method are the same as those of FIG. Figure 6 Consistent in.

[0055] like Figure 7 FIG. 1 is another use state diagram of the door blocking device, in which the door blocking device is used on a box elevator with doors opening up and down. The door blocking device is installed at the position of the floor door 102 for opening up and down to prevent the floor door 102 for opening up and down from descending, so as to ensure that the floor door 102 for opening up and down is in a certain door opening state. When blocking the door, the door blocking device is installed in the vertical door frame guide groove 1021, and the floor door guide surface of the floor door 102 for opening up and down is pressed against the door blocking inclined surface to achieve door blocking.
