DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Embodiment 1
[0020] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A safety suspension protection device for elevator anti-falling. This protection device is used for elevators and tightly locks in case of the hanging elevator falling. The installation of the elevator anti-falling protection device belongs to the existing mature technology and has no obvious connection with the technical features described in the text, so it will not be elaborated too much. It includes a fixed seat 1. An installation disk 2 is installed on the side wall of the fixed seat 1. A braking component is arranged at the front end of the installation disk 2. The braking component is composed of a brake drum 3 and a guide wheel 6. A steel wire rope 8 is also arranged at the front end of the installation disk 2. Installation blocks 4 are connected to the upper and lower ends of the brake drum 3. Bolts 5 are connected to the surface of the installation blocks 4. Grooves 11 are formed on the surface of the installation disk 2. Nuts 12 are connected to the surface of the bolts 5. A connecting component 7 for the guide wheel 6 is also arranged at the front end of the installation disk 2. Baffles 9 are arranged at the upper and lower ends of the brake drum 3. Screws 10 are connected to the surface of the baffles 9.
[0021] Preferably: The brake drum 3 is fixedly connected to the installation disk 2 through the bolts 5 and the nuts 12.
[0022] Preferably: Four guide wheels 6 are provided and are divided into two groups. Each group of guide wheels 6 has two and is distributed up and down at both ends of the brake drum 3.
[0023] Preferably: The baffle 9 is fixedly connected to the brake drum 3 through the screws 10.
[0024] Preferably: The connecting component 7 includes a connecting block 71, a bidirectional lead screw 72, a bearing 73 and a threaded sleeve 74. The connecting block 71 is connected to the front end of the installation disk 2. The bidirectional lead screw 72 is arranged inside the connecting block 71. The bearing 73 is installed at one end of the bidirectional lead screw 72. The threaded sleeve 74 is threadedly connected to the surface of the bidirectional lead screw 72.
[0025] Preferably: A threaded hole is formed at the front end of the threaded sleeve 74, and one end of the guide wheel 6 is threadedly connected to the threaded hole.
[0026] In the embodiments, when the protection device is installed and used, first, the steel wire rope 8 passes through the baffle 9 and is located between the two brake drums 3, and is also located between the guide wheels 6. Subsequently, the distance between the brake drum 3 and the guide wheel 6 is adjusted according to the size of the steel wire rope 8. 1. Adjustment of the brake drum 3: First, loosen the connection between the nut 12 and the bolt 5 to allow the brake drum 3 to drive the bolt 5 to move within the groove 11. Then, after adjusting the position of the brake drum 3, tighten the nut 12 again to complete the adjustment of the brake drum 3. 2. Adjustment of the guide wheel 6: First, rotate the bidirectional lead screw 72 to rotate within the connecting block 71 along the bearing 73. Then, the threaded sleeve 74 moves along the opposite threads on the surface of the bidirectional lead screw 72. At the same time, the threaded sleeve 74 drives the guide wheel 6 connected to the front end to move, thus completing the adjustment of the guide wheel 6. Then, the guide wheel 6 and the brake drum 3 cooperate to make the outer wall of the steel wire rope 8 fit with the brake drum 3 and the guide wheel 6, which can be tightly locked in case of an elevator fall to prevent the elevator from falling.
[0027] It should be noted that the connection end of the brake drum 3 and the baffle 9 is provided with a connection hole identical to the groove 11, which avoids the situation where the brake drum 3 cannot be adjusted after the baffle 9 is fixed. When the brake drum 3 is adjusted, the connection with the baffle 9 can be loosened, and the baffle 9 can be fixed again after adjustment.
[0028] In another embodiment, first, the distance between the brake drum 3 and the guide wheel 6 is adjusted according to the diameter of the steel wire rope 8. The adjustment of the brake drum 3 and the guide wheel 6 can refer to the description in the above embodiments. Then, a suitable baffle 9 is selected to facilitate connection with the adjusted brake drum 3, so that the baffle 9 will not affect the normal adjustment of the brake drum 3. Subsequently, the baffle 9 is located at the upper and lower ends of the brake drum 3 to prevent sand and gravel from falling into the brake drum 3 and causing the brake drum 3 to malfunction.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
