Abstract

The utility model relates to a hand operated hanging basket for overhead work, which comprises a platform, a rope and a lifting machine. The utility model is characterized in that the lifting machine and a safe lock are arranged on the platform. A main rope is fixed on the ground surface by a pulley block of the lifting machine, which is composed of a moving wheel, a column gear, and a spline gear, and an auxiliary rope is fixed on the ground surface after the auxiliary rope penetrates through two clamping blocks of the safe lock. Because the utility model adopts the main rope structure, the auxiliary rope structure and the safe lock structure, the safe lock immediately acts and clamps the auxiliary rope once the main rope has accidents. Clamping force and gravity on the platform are in direct proportion. In addition, the utility model has the advantages of high safety, reliable action and convenient operation.

Description

Manual high-lift operation hanging cradle

Technical field

The utility model relates to high-rise implement technical field, particularly a kind of manual high-lift operation hanging cradle that is used for highrise building application, insulation, maintenance, cleaning and installation.

Background technology

A kind of work high above the ground mode at present commonly used is to tie up on the wooden stick with a rope, above the operator is sitting in, operates on one side, to transferring rope, and its shortcoming is a poor stability, and can only operate also inconvenience to transferring rope.

Summary of the invention

The purpose of this utility model provides good, the easy to use manual high-lift operation hanging cradle of a kind of safety.

The utility model is to realize like this, it comprises platform, rope and elevator, it is characterized in that on platform, being provided with elevator and safety lock, the main rope by fixing on the ground behind two fixture blocks that the elevator assembly pulley that is made of driving wheel, stud wheel and spline gear fixes on the ground, secondary rope passes safety lock.

The utility model has been owing to adopted major and minor rope and safety lock structure, in case main rope meets accident, safety lock moves immediately and clamps secondary rope, and its clamping force is directly proportional with gravity on the platform, have safe, reliable in action and advantages of simple operation.

The specific embodiment

Shown in Fig. 1-7, this manual high-lift operation hanging cradle comprises platform 1, main rope 2, secondary rope 3, safety lock 4, elevator 5, riser 6, buckle 7, directive wheel 8, the axis of guide 9, driving wheel 10, ratchet 11, spring 12, ratchet 13, locking plate 14, power transmission shaft 15, end cap 16, bearing support 17, spline gear 18, stud wheel 19, guide wheel 20, wheel shaft 21, swing arm 22, seat board 23, torque arm 24, torsionspring 25, axle 26, axle sleeve 27, side plate 28, axle 29, clamp 30 and back-up ring 31, it is provided with two cover elevators 5, the main rope 2 of two covers, the secondary rope 3 of two covers, elevator 5 and safety lock 4 are installed in the two ends of platform 1 respectively, elevator 5 is following, safety lock 4 is last, main rope 2 passes through by driving wheel 10, the elevator assembly pulley that stud wheel 19 and spline gear 18 constitute fixes on the ground, secondary rope 3 fixes on the ground after passing two clamps 30 of safety lock 4, guide wheel 20 on the secondary rope is pressed on the main rope 2 and makes safety lock 4 be in equilibrium state, spring 12 matches with swing arm 22, operating principle is by shaking the handle of elevator 5, make power transmission shaft 15 drive stud wheel 19, spline gear 18, driving wheel 10 and directive wheel 8 rotate, thereby make on the platform, following motion, while power transmission shaft 15, stud wheel 19 and spline gear 18 have constituted the self-locking mechanism of elevator 5, when not carrying out lifting, can make platform 1 keep allocation, secondary rope 2 is to pass in the middle of the clamp 30 of safety lock 4, usually the guide wheel 20 of safety lock 4 is pressed in main rope last 2, main rope 2 is given its reaction force, safety lock place 4 is in equilibrium state, 30 pairs of secondary ropes 3 of clamp do not produce clamping force, when fortuitous event appears in main rope 2, the external force that acts on the guide wheel 20 disappears, under the effect of spring 25, its swing arm 22 is to left movement, drive clamp 30 pair rope 3 is clamped, prevent unexpected the generation.

Claims

1, a kind of manual high-lift operation hanging cradle, it comprises platform, rope and elevator, it is characterized in that on platform, being provided with elevator and safety lock, the main rope by fixing on the ground behind two fixture blocks that the elevator assembly pulley that is made of driving wheel, stud wheel and spline gear fixes on the ground, secondary rope passes safety lock.
