Description

Technical Field

[0001] This patent relates to the field of host shock absorption technology, specifically a hydraulic host shock absorption module. Background Art

[0002] The elevator main unit is the elevator's driving component. When the main unit is in operation, it generates vibrations. To isolate the vibration and noise, the main unit and the main frame require a main unit shock-absorbing pad. Existing main unit shock-absorbing systems on the market primarily use rubber shock-absorbing pads. However, given that the main unit's center of gravity is not at the geometric center, the forces acting on the four corners vary, requiring different hardness levels for the main unit shock-absorbing pads. Currently, to address this issue, engineers need to calculate the forces and design the shock-absorbing pads for each main unit model. This is a complex task and has limited accuracy. Therefore, we propose a hydraulic main unit shock-absorbing module. Patent content

DETAILED DESCRIPTION

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

[0021] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 This patent provides a technical solution: a hydraulic main engine shock absorption module, including a shock absorption unit 1 and a detection unit 2, the shock absorption unit 1 includes an oil pump 11, an oil pipeline 12, a piston mechanism 13 and hydraulic oil 14, the piston mechanism 13 includes a piston cylinder 131 and a piston 132, the lower end of the piston 132 is coaxially slidably installed in the piston cylinder 131, multiple piston mechanisms 13 are connected to the oil pump 11 through the oil pipeline 12, the hydraulic oil 14 is stored in the oil pump 11, the detection unit 2 includes a sensor component 21 and a controller 22, the sensor component 21 is arranged on the shock absorption unit 1 and is electrically connected to the controller 22, and the oil pump 11 is electrically connected to the controller 22.

[0022] The oil pump 11 drives the piston 132 to provide shock absorption for the main engine, and the detection unit 2 detects and feeds back the force applied to each bottom corner in real time. The controller 22 then analyzes the force, drives the oil pump, and adjusts the piston at each bottom corner to achieve active shock absorption. The detection unit 2 can be a photoelectric sensor that measures the distance between the upper and lower working surfaces, or it can be an oil pressure detection valve that detects the pressure on each oil pipeline 12. A buzzer can also be added, installed in the car or control room. Once the main engine vibrates abnormally, the detection unit recognizes it and feeds back to the staff through the buzzer.

[0023] Specifically, the sensor assembly 21 includes a photoelectric transmitter 211 and a photoelectric receiver 212 . The photoelectric transmitter 211 is disposed on the side of the piston 132 , and the photoelectric receiver 212 is disposed on the side wall of the piston cylinder 131 and corresponds to the photoelectric transmitter 211 up and down.

[0024] Specifically, the sensing assembly 21 includes an oil pressure detection valve 213 , which is disposed on the oil pipeline 12 .

[0025] Specifically, the detection unit 2 further includes a buzzer, which is electrically connected to the controller 22 .

[0026] Specifically, a rubber ring is provided on the upper end surface of the piston cylinder 131, and the Rockwell hardness of the rubber ring is 40-80. Limiting rings are provided at the upper and lower ends of the piston 132, and the distance between the two limiting rings is 10-50 mm.

[0027] In order to avoid the oil pump failure and temporary loss of shock absorption effect, a circle of rubber ring can be set between the piston cylinder 131 and the piston 132. The rubber ring does not work normally. Once the oil pump fails, the rubber ring can temporarily act as a shock absorber for the main engine.

[0028] Specifically, the shock absorbing unit 1 further includes a flow limiting valve 15 , which is disposed on the oil pipeline 12 .

[0029] If the oil pump fails, the hydraulic oil will flow back and the piston will drop to the bottom. In order to reduce the intensity of this action, a flow limiting valve 15 can be set on the oil pipeline 12 to make the hydraulic oil flow back relatively slowly.

[0030] Specifically, the oil pipeline 12 is detachably connected to the oil pump 11 and the piston mechanism 13 .

[0031] In order to facilitate the increase or decrease of the number of pistons and maintenance and replacement, the piston mechanism and oil pipeline can be disassembled.

[0032] Specifically, the piston cylinder 131 includes a lower cylinder body 1311 and an upper cylinder body 1313. The left and right ends of the outer wall of the lower cylinder body 1311 are integrally formed with mounting rings 1312, and the left and right ends of the outer wall of the upper cylinder body 1313 are integrally formed with mounting plates 1314. The bottom of the mounting plate 1314 is integrally formed with a screw 1315. The bottom end of the screw 1315 passes through the mounting ring 1312 and is threaded with a nut 1316. A sealing ring 1317 is provided between the lower cylinder body 1311 and the upper cylinder body 1313, and the lower cylinder body 1311 and the upper cylinder body 1313 are pressed tightly on both sides of the sealing ring 1317.

[0033] By dividing the piston cylinder 131 into the lower cylinder body 1311 and the upper cylinder body 1313 , it is convenient to install the piston 132 in the piston cylinder 131 in the early stage.

[0034] Working Principle: The oil pump 11 drives the piston 132 to provide shock absorption for the main engine. The detection unit 2 provides real-time feedback on the force applied to each bottom corner. The controller 22 then analyzes the force, drives the oil pump, and adjusts the piston at each bottom corner to achieve active shock absorption. The detection unit 2 can be a photoelectric sensor that measures the distance between the upper and lower working surfaces, or an oil pressure detection valve that detects the pressure on each oil pipeline 12. A buzzer can also be added, installed in the car or control room. If the main engine vibrates abnormally, the detection unit will identify it and provide feedback to the staff through the buzzer.
