Description

Remote electrically controlled tower crane

Technical field

The utility model relates to a kind of construction machinery and equipment, particularly relates to a kind of remote electrically controlled tower crane.

Background technology

Tower crane is called for short the tower machine, also claims tower crane, originates from West Europe.According to record, first relevant tower machine patent for building issued in 1900.Occurred the fixing hoisting crane that jib is housed of body of the tower in 1905, nineteen twenty-three has been processed the prototype machine of tower machine in modern age, the same year occurs first more complete tower machine in modern age.Nineteen thirty at that time Germany begun batch manufacturing tower machine, and be used for building operation.The technology of tower machine is more and more advanced, and Applicable scope is also more and more wider, not only uses at traditional building field; Also used widely in the various fields of lifting that need, thereby alleviated people's labour intensity, with regard to the cotton industry; Adopt manual work to carry out to the lifting of cotton, labour intensity is big more, and efficient is low; To above deficiency, present cotton industry also progressively adopts hoisting crane to lift, but many employings is existing hoisting crane; So not enough below existing: because cotton is on fire easily, and how existing hoisting crane is provided with electrical controller above that, so; Electro spark or electric leakage etc. will occur,, make cotton in hoisting process, have serious potential safety hazard so there is the possibility of presence of fire.

The utility model content

The utility model technical matters to be solved is to provide a kind of efficient height, safe remote electrically controlled tower crane of lifting.

The technical scheme of the utility model is following: a kind of remote electrically controlled tower crane; Comprise tower crane frame, arm and operator's compartment; Said operator's compartment is installed on the said tower crane frame, and said arm middle part is supported on the said tower crane frame, and its main points are: be fixed with left and right roller cage respectively in said tower crane frame both sides; On a said bracing frame that rolls left, be supported with first cylinder and second tin roller; This first cylinder and second tin roller are arranged in parallel, and on said right roller cage, are supported with the 3rd cylinder and the 4th cylinder, and the 3rd cylinder and the 4th cylinder are arranged in parallel; Said arm is made up of two angle bar beams that are arranged side by side; Between two these angle bar beams, be provided with the first sliding roller and the second sliding roller; This first sliding roller and the second sliding roller can slide on said arm; Side away from said tower crane frame is provided with winch; The first halliard outer end on this winch ties up on the suspension hook behind a circle on said this first cylinder, second tin roller and the second sliding roller, and the outer end of second halliard on this winch ties up on the said suspension hook behind a circle on said the 3rd cylinder, the 4th cylinder and the first sliding roller; On said arm, be provided with stay cord, the two ends of this stay cord tie up to respectively on the first sliding roller and the second sliding roller, and on the rolling disc of this stay cord in the said operator's compartment.Adopt above structure, on suspension hook, hang with the cotton bag, start winch; Under the effect of winch, first halliard and second halliard spur said suspension hook and rise, thereby the cotton bag is upwards promoted; When the cotton bag was risen to desired height, the control winch stopped, at this moment; Be positioned at the operating personal hand rotation rolling disc of operator's compartment, rolling disc drives stay cord and moves, thereby makes the stay cord pulling first sliding roller and the second sliding roller on said arm, move; Finally make suspension hook drive the cotton bag and on arm, move, realize the lifting of cotton bag.In the above structure, winch is arranged on the place away from said tower crane frame, as can winch being placed on outside the cotton factory, thereby makes to have no electrical equipment in the whole cotton factory, eliminated the hidden danger that cotton catches fire.In the above structure; With first lift cord wrapping on said first cylinder and second tin roller; With second lift cord wrapping on said the 3rd cylinder and the 4th cylinder; Thereby make the utility model that a buffering arranged in hoisting process, avoid the fast rise of cotton bag or the potential safety hazard that descends and cause fast.Simultaneously, the employing of the utility model makes that the lifting of cotton bag is convenient, has reduced labour intensity, and has improved lifting efficient.

At two said angle bar beam both ends first deflector roll and second deflector roll are installed respectively; At two this angle bar beam middle parts the 3rd deflector roll and the 4th deflector roll are installed; The said first halliard outer end ties up on the suspension hook behind a circle on said this first cylinder, second tin roller, the 3rd deflector roll, first deflector roll, second deflector roll and the second sliding roller successively; The said second halliard outer end ties up on the said suspension hook behind a circle on said the 3rd cylinder, the 4th cylinder, four deflector rolls, second deflector roll, first deflector roll and the first sliding roller successively; And in said operator's compartment, brake is installed; Said first halliard and second halliard pass said brake, and this brake can be blocked said first halliard and second halliard; Said stay cord is also on said first deflector roll and second deflector roll.Adopt above structure; When the cotton bag on being lifted on suspension hook rises to the height that needs; The operator starts brake; Thereby the time cotton bag keep certain height; At this moment, the pulling stay cord moves win deflector roll and second deflector roll on arm, because the said first halliard outer end ties up on the suspension hook behind a circle on said this first cylinder, second tin roller, the 3rd deflector roll, first deflector roll, second deflector roll and the second sliding roller successively; The said second halliard outer end ties up on the said suspension hook behind a circle on said the 3rd cylinder, the 4th cylinder, four deflector rolls, second deflector roll, first deflector roll and the first sliding roller successively, thereby makes win deflector roll and second deflector roll clog-free moving on arm.

Said suspension hook is a Lever Blocks, on this suspension hook, also hangs with hook.Adopt above structure, suspension hook rotated to be the palm cucurbit, can manual regulation the height of cotton bag on the hook.

Said tower crane frame, left and right roller cage are fixed on the pedestal, on this pedestal, roller are installed.Adopt above structure, can be good at realizing moving of the utility model, range of use is wider.

Beneficial effect: the utility model is through being arranged on winch in the place away from tower crane frame, thereby solved the potential safety hazard when the utility model uses, and reduced operator's labour intensity simultaneously, improved production efficiency; The utlity model has characteristics such as cost is low, simple in structure, good reliability, safety height.
