Detailed description of the invention
Fig. 2-3 is structural representations of a kind of embodiment 1 of lifting Weight-measuring device, a kind of lifting Weight-measuring device comprises the fixed pulley 1 that pulling force sensor 3, pulley yoke 2 and axis extend along the longitudinal direction, pulley yoke 2 is U-shaped structure, fixed pulley 1 is rotated by bearing pin and is arranged on two external parts of U-shaped pulley yoke, U-shaped pulley yoke lower end is installed in the upper end of pulling force sensor, and the lower end of pulling force sensor is installed with the spin-ended assembly that slides.The spin-ended assembly that slides comprises for being installed in permanent seat 5 in winch frame and sliding the spin-ended cliding seat 4 coordinated with permanent seat 5, and cliding seat 4 is fixed together with the lower end of pulling force sensor and slides along the longitudinal direction.
In the present embodiment, above-mentioned cliding seat 4 is sleeved on permanent seat 5, and with permanent seat 5 bearing fit, cliding seat 4 coordinates with the spin-ended plane on the contact surface of permanent seat 5 is spin-ended by being separately positioned on cliding seat 4 with permanent seat 5.For the ease of production and processing, above-mentioned cliding seat 4 all adopts square hollow section to make with permanent seat 5, cliding seat 4 adopts the square hollow section of large scale make thus form square shaft, permanent seat 5 adopts the square hollow section of small size make thus form square sliding sleeve, two square hollow sections are set in together, the endoporus of the square hollow section of large scale slides spin-ended cooperation with the outside face of the square hollow section of small size, cliding seat 4 can be moved forward and backward along permanent seat 5, and spinning upside down around permanent seat 5 does not occur.In order to the axis direction of the direction of slip with fixed pulley that ensure cliding seat is consistent, the installation direction of permanent seat 5 is set to axis and installs along the longitudinal direction.
Fig. 4 is a kind of structural representation of embodiment 2 of lifting Weight-measuring device, the difference part of the present embodiment and embodiment 1 is: cliding seat is without the need to being sleeved on permanent seat, above-mentioned permanent seat can also be selected to the channel-section steel 12 be solid-located by bolt and frame 6, the bottom end face of channel-section steel offers the elongated hole run through up and down, and elongated hole extends along the longitudinal direction.Above-mentioned cliding seat comprises adapter plate 11, and adapter plate 11 is also installed with two-thread screw, and cliding seat is fixed together by the lower end of nut on the upside of two-thread screw of the upside of two-thread screw and spinning and pulling force sensor.The downside of two-thread screw screws upper locking nut through after the elongated hole of channel-section steel, after installation, two-thread screw slides in channel-section steel elongated hole, simultaneously, bottom surface due to adapter plate is fitted on the bottom end face of channel-section steel, and this prevents again cliding seat 4 spinning upside down around permanent seat.
The embodiment 3 of a kind of lifting Weight-measuring device as shown in Figure 5, the difference part of the present embodiment and embodiment 1 is: permanent seat is the circular shaft 14 extended along the longitudinal direction, circular shaft 14 offers the elongated hole radially run through, the length direction of elongated hole extends along the axis direction of this circular shaft.Be provided with the slip endoporus that arrange corresponding to this circular shaft in cliding seat 13, permanent seat be also provided with the bolt that arrange corresponding to above-mentioned elongated hole.Sliding base sleeve is contained on permanent seat, then by bolt and lock nut by permanent seat, cliding seat together with pulling force sensor separable joint, the slip endoporus of cliding seat and permanent seat bearing fit, cliding seat is coordinated with permanent seat is spin-ended by the bolt running through permanent seat elongated hole.
A kind of winch as shown in Figure 6, comprise the reel 8 that frame 6, drive motor 7 and axis extend along the longitudinal direction, reel 8 is arranged in frame 6, transmission device 9 is also provided with between drive motor 7 and reel 8, reel 8 is wound with steel rope 10, the frame 6 in the Steel wire rope discharge direction outside reel 8 is also provided with lifting weight device for measuring force, lifting weight device for measuring force is consistent with above-mentioned lifting weight device for measuring force structure, does not repeat them here.Lifting weight device for measuring force is installed in frame 6 by permanent seat, is connected after steel wire penetrating fixed pulley with by lifting heavy.
Principle of work of the present utility model: when winch lifting heavy, steel rope is tightened, the tension force of lifting heavy is delivered to fixed pulley 1 by steel rope 10, suffered power is passed to pulling force sensor 3 by the pulley yoke 2 of lower end by fixed pulley 1, pulling force sensor 3 exports corresponding resistance signal according to the size of the tension force of steel rope, and read out instrument resistance signal is sent in face of operating personal, read out instrument calculates according to the size of resistance signal and shows the weight of weight.
Be more than preferred embodiment of the present utility model, in other embodiments, pulley yoke can adopt other version, as long as can support fixed pulley and facilitate connecting sensor.Those skilled in the art also can in varied situations, and carry out equivalent replacement according to the design general knowledge of this area, it is all within protection domain of the present utility model.
