Description

Technical Field

[0001] The utility model relates to the technical field of passenger elevators, in particular to a safety locking structure for passenger elevators. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15 degrees to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways. It is a fixed lifting device that serves specified floors. A vertical elevator has a car that runs between at least two rows of rigid guide rails that are perpendicular or inclined at an angle of less than 15 degrees. The size and structure of the car facilitate the entry and exit of passengers or the loading and unloading of goods. According to the main needs, vertical elevators are divided into passenger elevators and freight elevators. Freight elevators are mainly used for loading goods, while passenger elevators are mainly used for loading passengers.

[0003] In the prior art, when a traction passenger elevator is in use, a locking structure needs to be installed at its traction motor for use. When the car suddenly falls, the traction motor is restricted, thereby restricting the traction rope to prevent the car from continuing to fall. Currently, the locking mechanism is mostly installed on the traction machine. A large pulley and a traction rope conveying wheel are set at the output end of the traction machine. When locking, the pulley is clamped by a locking clamp. After long-term use, the locking clamp and the pulley will wear out due to friction and need to be replaced. The pulley itself is heavy, and it is inconvenient to disassemble. The replacement cost is high, which not only increases the cost of use, but also increases the difficulty of maintenance. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that after long-term use, the locking clip and the wheel will wear out due to friction and need to be replaced. The wheel itself is heavy, inconvenient to disassemble, and the replacement cost is high, which not only increases the cost of use but also increases the difficulty of maintenance. A passenger elevator safety locking structure is proposed to solve the problem in the prior art that the locking clip and the wheel will wear out due to friction after long-term use and need to be replaced. The wheel itself is heavy, inconvenient to disassemble, and the replacement cost is high, which not only increases the cost of use but also increases the difficulty of maintenance.

The clamping mechanism 4 includes a bottom support seat 41 and a pressing seat 42, which are arranged between the assembly mechanism 5 and the conveying wheel 2.

[0023] The following is a detailed description of the specific settings and functions of this embodiment. The grinding sleeve 51 is installed at one end of the connecting shaft 6. It is not only small in size, but also has no obstruction on the installation side, making disassembly and installation more convenient and the replacement cost lower. It is fixed by plugging and bolting, and the installation efficiency is higher. The bottom support seat 41 and the pressing seat 42 are used to support the connecting shaft 6 to ensure the strength of use, avoid the traction motor 1 from tilting, and increase the stability of use. The double plug-in setting of the limit rod 57 and the limit sleeve 56 increases the connection strength. When locking, the stability is higher and it is not easy to disengage, thereby ensuring the stability of use.

[0024] Example 2: Figure 1 - Figure 4As shown, the inner ring surface of the conveying wheel 2 is fixedly connected with the reinforcing rib 3, and a connecting box 52 is provided on one side of the grinding sleeve 51. The outer surface of the connecting box 52 is fixedly connected with the fan blade 53. The connecting box 52 is fixedly connected to the grinding sleeve 51 and the connecting shaft 6 by the provided bolts. The bottom support seat 41 is fixedly connected to the pressing seat 42. The upper end of the bottom support seat 41 and the middle part of the lower end of the pressing seat 42 are both provided with an assembly groove 45. The inside of the assembly groove 45 is provided with a bearing 44, and the bearing 44 is fixedly connected to the connecting shaft 6. The middle part of one side of the pressing seat 42 is fixedly connected with a mounting bracket 43. A two-way hydraulic cylinder 412 is fixedly connected to one side of the bottom support seat 41. One end of the two mounting brackets 43 is provided with a No. 2 pressure plate 411. A No. 1 pressure plate 410 is provided on one side of the No. 2 pressure plate 411. A connecting seat 46 is rotatably connected between the No. 1 pressure plate 410 and the No. 2 pressure plate 411. A card slot 48 is provided on one side of the connecting seat 46, and a card block is inserted into the inside of the card slot 48 49, one side of the block 49 is fixedly connected with the grinding block 47, one end of the connecting seat 46 is fixedly connected with the sealing plate 413, the second pressure plate 411 is fixedly connected to the lower end of the first pressure plate 410 by bolts, the second pressure plate 411 and one end of the bolt at the lower end of the two-way hydraulic cylinder 412 are movably connected to the two ends of the two-way hydraulic cylinder 412, a threaded rod is set on one side of the second pressure plate 411, the threaded rod is located above the middle of the second pressure plate 411, and is connected to the connecting seat 46 by the threaded rod. Rotational connection, the connection area is a bare rod. After connecting with nuts, the connecting seat 46 is limited between the No. 1 pressure plate 410 and the No. 2 pressure plate 411. After installing the nut at one end of the mounting frame 43, the No. 2 pressure plate 411 is connected to the upper end of the No. 1 pressure plate 410. There is an interference fit between the No. 2 pressure plate 411, the No. 1 pressure plate 410 and the connecting seat 46. The bolt connecting the lower end of the No. 2 pressure plate 411 and the No. 1 pressure plate 410 and the connection with the two-way hydraulic cylinder 412 is a bare rod.

[0025] The effect achieved by the entire embodiment is that the connecting seat 46 and the grinding block 47 are installed in a plug-in manner and restricted by the sealing plate 413, which makes replacement more convenient and has a low cost. By using a lever, when locking, the grinding block 47 has a greater squeezing force on the grinding sleeve 51, and the locking effect is better. Through the arrangement of the connecting box 52 and the fan blades 53, when locking, due to the high rotation speed of the connecting shaft 6, the fan blades 53 can cause airflow to flow, thereby dissipating heat to the grinding sleeve 51 and the grinding block 47 and reducing wear.

[0026] The usage and working principle of this device: when locking is required, the two-way hydraulic cylinder 412 contracts, causing the two grinding blocks 47 to squeeze the grinding sleeve 51 and restrict the connecting shaft 6 until the connecting shaft 6 stops rotating and locks. After locking, the grinding sleeve 51 and the grinding block 47 are worn and need to be replaced. When disassembling the grinding sleeve 51, the bolts on the connecting box 52 are removed. After taking out the connecting box 52, the bolts in the limit sleeve 56 are removed, and the grinding sleeve 51 can be pulled out, and then the new grinding sleeve 51 can be installed. When replacing the grinding block 47, the bolts on the sealing plate 413 are removed, and the grinding block 47 can be pulled out and replaced. After the replacement is completed, the two-way hydraulic cylinder 412 is extended to adjust the rotation angle of the connecting seat 46 so that the grinding block 47 does not contact the grinding sleeve 51.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
