Problems solved by technology
attached Figure 9 As shown, the force and speed measurement device realizes the above functions through the floating of the pulley on the two beams and the chain, but there are two problems in this device: 1. Because the initial drag point of the winch is different each time, the force and speed measurement device is installed separately The location will be different, which will make the installation difficult
2. Since the force and speed measurement sensor is in a floating state when the winch is working, when the tension and speed change, the force and speed measurement sensor will vibrate, which will affect the measurement accuracy

Embodiment 1
[0032] The hoisting device for the force and speed measurement sensor of the drum winch is composed of a hoisting frame, a force and speed measurement sensor 1 and a hoisting slideway 5; The hanger 2 is connected to the force speed measuring sensor 1, and the sliding frame 3 is assembled on the lifting slideway 5 and can move along the lifting slideway 5.
[0033] Annular groove is arranged on hanger 2 both sides plates, is symmetrically provided with two holes on force velocity measuring sensor 1, is worn with axle 12 in the hole, and axle 12 is assembled into one by bearing 13 and hanger 2 both sides plate annular grooves. The hanger 2 is connected with the trunnion 4 through the shaft 8 and the bushing 9 to form a rotary motion pair. The trunnion 4 is assembled on the sliding frame 3 through a shaft structure, and the threaded shaft 11 is screwed into the trunnion 4 through threads, and the bearing 10 is connected with the sliding frame 3 in the middle to form a rotary moti...

The invention relates to a hoisting device of a force speed measuring sensor of a drum winch, and belongs to the measurement technology field of dragging winches. The hoisting device of the force speed measuring sensor of the drum winch comprises a hoisting frame of the force speed measuring sensor and is characterized in that: the hoisting device is composed of the hoisting frame, the force speed measuring sensor and a hoisting slideway; the hoisting frame is composed of a hanging frame and a sliding frame, the hanging frame is assembled on the sliding frame for hoisting and installing the force speed measuring sensor, and the sliding frame is assembled on the hoisting slideway and can be moved along the hoisting slideway. The hoisting device and the drum winch are integratedly installed, thereby realizing the integration of the measurement of the winch without the need of installing the sensor repeatedly at each time of construction; the measurement precision is not affected by the change of construction sites, and the rope stretching speed of a drum steel wire rope and the received tension value thereof can be measured conveniently and accurately.
Description
technical field [0001] The invention belongs to the technical field of drag winch measurement, in particular to a hoisting device for a drum winch force speed measurement sensor. Background technique [0002] At present, the working process of the drum winch of the known technology measures the tension and speed of the wire rope, as attached Figure 7 , Figure 8 and Figure 9 . Usually a three-pulley force speed measurement sensor 15 is used. The steel wire rope 18 passes through the middle of the upper pulley 19 and the lower pulley 20. When the steel wire rope is tightened, its tension is supported by the three pulleys and acts on the pin sensor of the upper pulley 19. Through the strain of the sensor Measured tensile force, while the motion of the wire rope drives the upper pulley 19 to rotate, and the encoder 17 is driven to obtain the linear velocity of the wire rope after the gear transmission speeds up. [0003] When the drum winch is working, the force velocity m...
