Problems solved by technology

For the self-elevating platform, when the driving mechanism of the lifting system drives the lifting unit to make the legs move to cause the platform to move up and down, in order to ensure the safety and reliability of the platform moving up and down, that is, the deceleration system of the lifting unit does not appear to be overloaded. During operation, it is necessary to monitor the load status of the deceleration system in real time, and to correct the speed of the platform’s up and down movement in real time according to the corresponding load status, so as to play the role of overload protection. However, judging from the current public technology, there is no application in self-lifting Torque sensor for the output pinion of the platform lifting unit

Embodiment 1

[0009] Example 1: Combining figure 1 , figure 2 , the present invention is a kind of torque sensor that is used for the output pinion of self-elevating platform lifting unit, and it is made of left input end cover (1), transmission rod (2), connecting head (3), torque input shaft (4), Sensor end cover (5), sensor fixing flange (6), sensor body (7), strain gauge (8), signal transmission line (9), signal processing circuit (10), sensor right end fixed end cover (11), sensor The casing (12) and the output pinion (13) are composed, the left input cover (1) is coaxially connected with the transmission rod (2) and threaded, and the transmission rod (2) is coaxially connected with the connecting head (3) and threaded, The connector (3) is coaxially connected with the torque input shaft (4), and the torque input shaft (4) is fixedly connected with the sensor body (7) through the fixed end cover (11) at the right end of the sensor, and fixed to the sensor end cover (5) through a bear...

Embodiment 2

[0010] Example 2: Combining figure 1 , figure 2 , the working principle of the present invention is as follows: the left end of the pinion shaft (13) is subjected to the effect of moment, so that the left and right sections of the pinion shaft (13) produce relative displacement, and the displacement passes through the left input end cover (1), the transmission rod (2), Connector (3), torque input shaft (4), fixed end cap (11) at the right end of the sensor are transmitted to the sensor body (7) fixedly connected to the right end of the pinion shaft (13) on the sensor housing (12), and are pasted on The strain gauge (8) on the strain beam of the sensor body (7) feels the deformation, so that the signal of the full-bridge circuit composed of the strain gauge (8) changes, and the changed signal is transmitted to the processing circuit (10) through the signal transmission line (9). After the corresponding processing, the obtained signal is transmitted to the external post-proces...

Abstract

The invention provides a force moment sensor for an output pinion of a self-elevating platform elevating unit, which consists of a left input end cover, a transferring rod, a connector, a force moment input shaft, a sensor end cover, a sensor fixing flange, a sensor body, a strain gauge, a signal transmission line, a signal processing circuit and the output pinion. The transferring rod is connected with the connector, the connector is coaxially connected with the force moment input shaft, and the force moment input shaft is connected with the sensor body. The strain gauge is fixedly adhered on a strain beam of the sensor body, and the transferring rod is coaxial with the output pinion and penetrates through a central hole of an output pinion shaft. The force moment sensor for the output pinion of the self-elevating platform elevating unit obtains load situations of an elevating unit deceleration system in real time, immediately adjusts platform moving speed according to the load situations and performs platform overload protection. The force moment sensor avoids a pinion breaking phenomenon after overload, inputs all of force moment signals into a control system, monitors stress situations of platform pile legs in real time, is matched with control of a motor, averages the force moment of the pinion and provides guarantee for safe operation of a platform.

Description

(1) Technical field [0001] The invention relates to a sensor, in particular a torque sensor used for the output pinion of a jack-up platform lifting unit. (2) Background technology [0002] The self-elevating platform is composed of the main body of the platform, the legs and the lifting unit, and the platform moves up and down along the legs by the lifting unit. When the jack-up platform is working, the legs are lowered and inserted into the seabed, and the platform is lifted to a safe working height away from the sea surface to ensure that the legs will not sink when the platform encounters a storm. After the completion of the well, the platform is lowered to the sea surface, the legs are pulled out and all lifted, and the whole platform floats on the sea surface and is towed to a new well location by a tugboat. Among them, the lifting unit is a key part of the jack-up platform lifting system, which directly affects the safety of the jack-up platform lifting process. At ...
