Embodiment

[0023] Example: UDM100-W winch

[0024] With reference to Fig. 2a, Fig. 2b and Fig. 3, weld a metal square frame with square steel pipe as winch frame 6, as shown in Fig. 2a, Fig. 2b; In the middle of this winch frame 6, fix two crossbeams that support usefulness up and down, The two vertical beams used for side fixed support, and the two guide pulleys 2 are respectively fixed on the two vertical beams of the winch frame 6; then, according to the requirements of the depth measurement, a high-strength plastic bucket with a suitable radius and length is selected to make a steel wire rope drum 1. Wire rope drum 9 and cable drum 8. The radius of wire rope drum 1 and wire rope drum 9 is identical. The radius ratio of the two wire rope drums and the cable drum 8 is directly proportional to the transmission ratio between them; the first wire rope drum 1 and the second wire rope drum 9 are installed coaxially. There are two steel wire ropes, the two steel wire ropes are respectively...

Abstract

The invention relates to a roller winch when the drilling trough wall verticality is measured. The invention includes a winch frame; the upper and the lower middle parts of the winch frame are fixed with two transverse beams, the side surface is fixed with two vertical beams; a guide pulley is fixed to the two vertical beam; a first steel wire rope cylinder and a second steel wire rope cylinder are coaxially arranged; two steel wire ropes are respectively fixed to the first and the second steel wire rope cylinders; the other end of the steel wire ropes are respectively provided with a connecting pin; the two steel wire ropes and the fixing frames are connected by the two connecting pins; a sensor is arranged on the fixing frame; the cable of the sensor is connected to the cable cylinder; a motor is directly arranged on the shafts of the first steel wire rope cylinder and the second steel wire rope cylinder; by the rotation of the motor, the synchronous rotation of the first steel wire rope cylinder and the second steel wire rope cylinder are driven; the rotation of the steel wire rope cylinder is transmitted to the cable barrel by the chain which is driven for synchronous rotation, thus the sensor is connected with the steel wire rope, the cable and two steel wire ropes synchronously stably motion up and down under the driving of the motor.

Description

technical field [0001] The invention relates to an electronically controlled winch used for measurement in construction engineering, in particular to a roller used for measuring the verticality of boreholes and the verticality of groove walls in the construction of underground diaphragm walls, etc., or for measuring the attitude of objects that need to be lifted winch. Background technique [0002] At present, in urban construction and major engineering construction (such as high-rise buildings, large bridges, etc.), it is often necessary to reinforce the foundation. One reinforcement method is to adopt bored piles; in some areas, urban subway construction needs to be excavated first. Deeper grooves are used to build underground diaphragm walls. Whether it is a borehole or a deep groove, it is difficult to ensure a certain verticality during the construction process, which requires testing the verticality of the borehole (well, groove) wall. At present, the commonly used d...
