Description

A kind of container hanging operating personnel's safety device

Affiliated technical field

The utility model relates to a kind of safety device of lifting operation personnel, especially is fit to the container hanging operation, does not stop conversion operating location personnel use, guarantees operating personnel's safety.

Background technology

At present when the container hanging operation in harbour, harbour and logistics goods yard, the operating personnel will implement operation around overhead several meters to tens meters high container top or freight container, the operating personnel must just can carry out the lifting operation of freight container after attachment point is fastened seat belts.Because the specification difference of freight container is piled high number of plies difference, the operating personnel needs continuous conversion operation point, and fastening seat belts could operation.The safety strap mooring points that has is not suitable for the operation of freight container, has both had container hanging operating personnel's potential safety hazard, has influenced work efficiency again.

Summary of the invention

For the inconvenience of the seatbelt lock that overcomes the continuous conversion of present container hanging operating personnel operation point, the utility model provides a kind of easy to carry, processing ease, fixing and shirk safety strap mooring points failure-free container hanging operating personnel's safety device.

The technical scheme in the invention for solving the technical problem is: the safety device of container hanging operation of the present utility model, be welded into casing with sheet iron, and have two mutually perpendicular circular holes on the casing, two axles are housed in circular hole.One is imput shaft, on the axle in casing the initiative taper generating gear is housed, and is fixing indicator board on the end axle outside the casing, and the other end prevents imput shaft moving axially at casing with packing ring, spring cotter location.The indicator board periphery is evenly equipped with four grooves, and on the corresponding position of groove locating dowel pin is housed, and when tongue has rotated 90 when spending, locating dowel pin relies on the elastic force of stage clip to embed the groove of indicator board automatically, is carved with the mark that shows tongue position on the indicator board.Imput shaft, initiative taper generating gear and indicator board are synchronous rotations.Another root is the tongue axle, on the axle in casing passive cone gear is housed, and is fixing the tongue that is complementary with the container hanging lockhole on the axle outside the casing.Tongue axle, passive cone gear and tongue are synchronous rotations.Casing is welded with a clamping rings outward, and an end of steel rope is connected on the clamping rings, and the other end is pegged graft into circle, to be used to connect operating personnel's safety strap.Rubber handle on the termination point casing of the outer imput shaft of casing is convenient to the operating personnel and is rotated imput shaft.When imput shaft is rotated, through the engaged transmission of cone gear, drive the rotation of tongue axle, make the tongue change of direction, thereby make tongue can enter or break away from the freight container lockhole of lifting operation easily.

The beneficial effects of the utility model are: the safety device volume is little, is easy to carry, and tongue enters or to break away from the container lock pore volume easy, has improved the safe reliability when the container operation personnel carry out lifting operation.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Casing among the figure [1], imput shaft [2], indicator board [3], initiative taper generating gear [4], tongue axle [5], packing ring [6], spring cotter [7], passive cone gear [8], tongue [9], rubber handle [10], locating dowel pin [11], annulus [12], steel rope [13], stage clip [14], support [15] and groove [16].

The specific embodiment

Be welded into a casing [1] with sheet iron, two mutually perpendicular circular holes are arranged on casing [1].Imput shaft [2] and tongue axle [5] are housed respectively in the circular hole.Load onto on the imput shaft [2] in the casing [1] initiative taper generating gear [4] is housed, one end of the imput shaft [2] that casing is outer is located with packing ring [6] and spring cotter [7], the other end is being fixed indicator board [3], and imput shaft [2], initiative taper generating gear [4] and indicator board are synchronous rotations.Indicator board [3] periphery has four grooves [16] that are evenly distributed, and with the corresponding position of groove locating dowel pin [11] is housed.When tongue [9] has rotated 90 when spending, locating dowel pin [11] relies on the elastic force of stage clip [14], embeds the groove [16] of indicator board [3] automatically, prevents the rotation of tongue [9].On the tongue axle [5] in the casing [1] passive cone gear [8] is housed, is fixing tongue [9] on the tongue axle [5] outside the casing [1].Tongue axle [5], passive cone gear [8] and tongue [9] are synchronous rotations.The outside weldings annulus [12] of casing [1], an end of steel rope [13] ties up on the clamping rings [12], and the other end is pegged graft into circle, and links together with operating personnel's safety strap, guarantees that the operating personnel's is safe, reliable.Operation rubber handle [10] is equipped with in the termination of imput shaft [2], when the operation personnel rotate rubber handle [10],, drive tongue axle [5] rotation through the engaged transmission of cone gear, change the direction of tongue [9], make tongue [9] can enter or break away from the lockhole that lifts freight container easily.Even continuous mobile lifting operation point as long as utilize the lockhole of freight container nearby, just can be fixed this safety device, improved container hanging operating personnel's safe reliability.

Claims (3)

1. a container hanging operating personnel safety device, it is characterized in that: load onto initiative taper generating gear and indicator board in imput shaft, load onto passive cone gear and tongue at the tongue axle, the initiative taper generating gear is meshed with passive cone gear, and locating dowel pin can embed the groove of indicator board.

2. a kind of container hanging operating personnel's according to claim 1 safety device is characterized in that: the indicator board groove and the locating dowel pin of rotation match.

3. a kind of container hanging operating personnel's according to claim 1 safety device is characterized in that: operating personnel's safety strap clamping rings direct by steel rope and on the casing is connected.
