Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The anti-drop device for the pipeline and the cable of the development machine as shown in the attached

drawings

1, 2, 3 and 4 comprises a device body 1, wherein a handle 2 is arranged on the device body, an anti-drop facility 5 is arranged in the device body, the device body comprises a bottom plate 3 and a top plate 4, the bottom plate 3 and the top plate 4 are two rectangular steel plates with the same size, the top plate 4 and the bottom plate 3 are horizontally arranged and are connected with four corresponding corners of the two plates by bolts, a space is reserved between the bottom plate 3 and the top plate 4 and can be adjusted, the anti-drop facility 5 is elastically arranged between the top plate 4 and the bottom plate 3, the pipeline is clamped by fixing or displacement when passing through a clamping surface of the anti-drop facility 5, and the pipeline of the development machine does not need to be permanently fixed, and the bolts can be adjusted when the pipeline needs to be disassembled and installed, the distance between the top plate and the bottom plate is increased, so that the spring is restored to the original state, and the pipeline is clamped by the clamping surface of the pipeline in a displacement mode, so that the pipeline is more convenient to disassemble or assemble.

The anti-falling facility 5 comprises a plurality of groups of clamping pieces 6, the clamping pieces 6 are linearly arrayed between the bottom plate 3 and the top plate 4, the top ends of the clamping pieces 6 are installed on the lower side of the top plate 4, the bottom ends of the clamping pieces are installed on the upper side of the bottom plate 3, and the clamping pieces are independent from each other.

The rubber wheel clamping piece 6 comprises a pair of rubber wheels 7 and a pair of springs, the rubber wheels 7 are installed at one ends of the springs, where the rubber wheels 7 are not installed, are vertically installed on the upper side of the bottom plate 3 and the lower side of the top plate 4 respectively, the two wheels are in contact with each other, and the springs are in a semi-contraction state. Replace steel sheet and pipeline direct contact with the gyro wheel, the advantage lies in the gyro wheel for the steel sheet in pipeline contact surface is more mellow and more, can reduce the wearing and tearing that the entry driving machine caused to the pipeline when removing, the spring of half contraction state possesses collapsible space promptly, has possessed certain elasticity again, during the installation pipeline, the spring shrink lets the pipeline pass through, the installation of being convenient for obtains enough big elasticity simultaneously for press from both sides tight pipeline, play good anticreep effect.

Rubber wheel 7 includes gyro wheel body 8 and support 9, be equipped with at least one draw-in groove 10 on the gyro wheel body, be equipped with an curved spring leaf 11 on the support 9, draw-in groove 10 uses 8 axle centers of gyro wheel body to arrange in gyro wheel body 8 side as the axle circumference, 11 one end of spring leaf is installed on the support, the position that gyro wheel body 8 was equipped with draw-in groove 10 is hugged closely to the face that 11 crooked directions of spring leaf are kept away from to spring leaf 11, and under 8 rolling states of gyro wheel body, when spring leaf 11 passes through draw-in

groove

10, 11 cards of spring leaf are gone into in draw-in groove 10.

Draw-in groove 10 is five rectangle draw-in grooves, just one side is equipped with fillet 12 in the five faces, 11 card of spring leaf is gone into during draw-in groove 10, fillet 12 with 11 external bend face contacts of spring leaf, and the spring leaf that goes into the draw-in groove when the gyro wheel rolls along fillet face orientation is ejecting by the fillet face, if rolls along the opposite direction, the gyro wheel then can be blocked by the spring leaf, if pack into along fillet face orientation when installing the pipeline, just can be more light, and the pipeline drops and also can be more difficult simultaneously, and the anticreep effect is showing.

Carry handle 2 and adopt the mode of digging the hole to run through the setting and be in bottom plate 3 and 4 both ends of roof, just it has rubber cushion 13 to wrap up on handle 2, and the processing method that directly punches is simple, and the hand is avoided hand and the steel sheet direct contact who has the edges and corners to wrap up the rubber cushion, holds more comfortablely in the hand, has increased the area of contact between hand and the handle simultaneously, and it is littleer to carry up hard, the installation of the transport and the device of being convenient for.
