AI Technical Summary
The overall height of the existing high-speed elevator pit component mounting seat is relatively low, which makes it difficult to adjust the installation height of the buffer component. In addition, water accumulation at the bottom of the elevator pit may affect the protective effect of the buffer component on the car, reducing the usability and practicality of the device.
Employing a lifting and quick-release mechanism, including an internally threaded sleeve, threaded rod, annular block, auxiliary handle, and telescopic rod, the device height can be adjusted. The buffer components can be quickly installed and removed via locking blocks and fixing rods, preventing water accumulation from affecting the buffering effect.
This invention enables the device height to be adjusted according to the actual conditions of the elevator pit, preventing water from submerging the buffer components, improving the device's usability and practicality, simplifying the operation steps, and enhancing the protective effect of the buffer components.

It includes a main mounting base, with a pair of main mounting bases and side mounting bases on opposite sides of the main mounting base. A pad is mounted on the main mounting base, and a support plate is mounted above the pad. The advantages of this invention are: by installing pads and support plates on the main and side mounting bases, several shock-absorbing springs in the middle provide a buffering effect when impacted, reducing the load on the main and side mounting bases. When the support plate is compressed and buffered, limiting plates reinforce its two sides, and support rods and connectors reinforce its other two sides, preventing the support plate from tilting or misaligning due to force. It also provides auxiliary support. The overall structure is reasonable, installation is convenient, and installation and assembly are mostly done with bolts or screws. It has a good buffering effect, greatly reducing the load on the mounting base and minimizing safety hazards.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an elevator pit component installation device, including a fixed base 1, a lifting mechanism 2, and a quick-release mechanism 3. The lifting mechanism 2 is disposed on the top of the fixed base 1 and includes an internally threaded sleeve 201, a threaded rod 202, an annular block 203, and a lifting plate 206. The top of the fixed base 1 is rotatably connected to one end of the internally threaded sleeve 201. The outer wall of the internally threaded sleeve 201 is fixedly connected to the inside of the annular block 203. The inner wall of the internally threaded sleeve 201 is threadedly connected to the outer wall of the threaded rod 202. One end of the threaded rod 202 is fixedly connected to the bottom of the lifting plate 206. The quick-release mechanism 3 is disposed on the fixed base 1. Above, the quick-release mechanism 3 includes a fixing rod 303 and a locking block 304. One end of the fixing rod 303 is rotatably connected to the top of the locking block 304. The top of the locking block 304 is in contact with but not connected to the bottom of the lifting plate 206. Multiple sets of damping rods 4 are fixedly installed on the top of the mounting plate 301. A pressure plate 6 is fixedly installed on one end of the damping rod 4. The top of the mounting plate 301 is fixedly connected to one end of the shock-absorbing spring 5. The other end of the shock-absorbing spring 5 is fixedly connected to the bottom of the pressure plate 6. The damping rod 4 passes through the interior of the shock-absorbing spring 5 but is not connected to it. A buffer pad 7 is fixedly installed on the top of the pressure plate 6. A set of positioning plates 8 are fixedly installed on both sides of the fixed base 1.
[0023] Secondly, the lifting mechanism 2 also includes auxiliary handles 204 and telescopic rods 205. Multiple sets of rectangularly distributed telescopic rods 205 are fixedly installed on the top of the fixed base 1. One end of the telescopic rod 205 is fixedly connected to the bottom of the lifting plate 206. Multiple sets of annularly distributed auxiliary handles 204 are fixedly installed on the outer wall of the annular block 203. The height of the device can be adjusted according to the actual situation of the elevator pit, and the installation position of the damping rod 4 and the shock-absorbing spring 5 can be raised to avoid water accumulation and flooding of the buffer components, ensuring the protective effect of the buffer components on the car, and improving the usability and practicality of the device.
[0024] Furthermore, the quick-release mechanism 3 also includes a mounting plate 301 and a connecting plate 302. The top of the lifting plate 206 is provided with the mounting plate 301, and multiple sets of connecting plates 302 are fixedly installed on both sides of the mounting plate 301.

There is no need to fix the buffer component with bolts, which simplifies the operation steps of the staff and makes the installation and disassembly of the buffer component more convenient and quick.
[0025] Working principle: In use, the fixed base 1 is installed at the bottom of the elevator pit through the positioning piece 8. The mounting plate 301 is placed on the lifting plate 206, so that the fixing rod 303 is located on both sides of the lifting plate 206. The locking block 304 is moved so that the locking block 304 rotates at the bottom of the fixing rod 303, locking the locking block 304 at the bottom of the lifting plate 206, thus completing the installation of the mounting plate 301 and the buffer components on it. To disassemble, simply rotate the locking block 304 in the opposite direction. By rotating the annular block 203 through each auxiliary handle 204, the internal threaded sleeve rod 201 is driven to rotate. Under the limit of the telescopic rod 205, the threaded rod 202 is driven to move upward inside the internal threaded sleeve rod 201, thereby driving the lifting plate 206 to move upward, thus raising the position of the pressure plate 6. When the elevator car falls, it absorbs energy initially through the buffer pad 7, and then presses the pressure plate 6 downward and compresses the damping rod 4, thus absorbing energy a second time from the pressure on the pressure plate 6.
[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
