Embodiment Construction
[0013] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments, but it should not be construed as a limitation on the technical solution.
[0014] like figure 1 As shown, the force-measuring and tensioning device of the double-suspension-point hoist hoist steel wire rope includes a gantry 1, a No. No. 1 gourd 2 and No. 2 gourd 3 are installed on the top, No. 1 spring balance 4 is connected below No. 1 gourd 2, and No. 2 spring balance 5 is connected below No. 2 gourd 3, forming a force measuring tension device as a whole.
[0015] Wherein, the gantry frame 1 is designed and manufactured according to different hoists and sites.
[0016] Among them, the specifications of the gourd and the measuring range of the spring balance are selected according to the specification and length of the wire rope.
[0017] like figure 1 As shown, the force measurement and tension installation method of the h...

The invention discloses a force-measuring tension device of steel wire ropes of a double-lifting-point gate lifting hoist and a mounting method of the steel wire ropes. Spring balances (4 and 5) are connected to a portal frame (1) correspondingly through hoists (2 and 3) to form the force-measuring tension device. The force-measuring tension device is installed at a rope drum of one side of the gate lifting hoist (6), the first spring balance (4) is connected with a point A of one steel wire rope, the second spring balance (5) is connected with a point B of the steel wire rope, the position isadjusted so as to enable the hoists to tension the steel wire rope vertically and upwards, the first hoist (2) tensions the portion, on the lower portion of the rope drum, of the steel wire rope, theread number a of the first spring balance 4 is written down, the second hoist (3) tensions the portion, on the upper portion of the rope drum, of the steel wire rope, the read number b of the secondspring balance (5) is written down, and the steel wire rope is anchored; and after mounting of the steel wire rope on one side is finished, the force-measuring tension device is moved to the positionof a rope drum on the other side of the gate lifting hoist, and the operations mentioned above are repeated. According to the force-measuring tension device of the steel wire ropes of the double-lifting-point gate lifting hoist and the mounting method of the steel wire ropes, the structure is simple, operation is simple and convenient, and the effects that the steel wire ropes on the two sides ofthe gate lifting hoist are equally tightened and tensioned, and the steel wire ropes on the two sides keep stressed equally during running of the gate lifting hoist are guaranteed.
Description
technical field [0001] The invention relates to the field of water conservancy project construction and operation management, in particular to a steel wire rope force measuring and tensioning device and an installation method thereof for ensuring equal force on both sides of the steel wire ropes during the operation of a double-suspension-point hoist hoist of the water conservancy project. Background technique [0002] The hoist hoist with double lifting points uses two (sets) of steel wire ropes to connect the gate. The force deviation of the steel wire ropes on both sides during operation should not exceed the relevant regulations. Hoist, gate lifting lug and other components will cause different degrees of damage, especially for arc gates, a large torque will be generated, which will endanger the safety of the door body, support arm, support hinge and hinge seat. At present, in the installation of steel wire ropes, some are connected to the hoist first and then the gate, ...
