Abstract

The invention discloses an electric tyre hoist which comprises an underframe. Traveling wheels and support legs are installed at the bottom of the underframe, a rotary table seat is installed on the upper portion of the underframe, a rotary table rotating around the rotary table seat is arranged on the rotary table seat, a rotating mechanism, a lifting mechanism, a luffing mechanism and an upper rotary column are arranged on the rotary table, a hoisting arm is installed on one side of the rotary table, a luffing pulley block is arranged on the hoisting arm via the upper rotary column, a balancing counter weight is arrange at the tail of the rotary table, and the upper rotary column is a detachable propeller strut. Since the luffing mechanism, the lifting mechanism and the rotating mechanism of the electric tyre hoist are arranged on the rotary table and the upper rotary column is of a detachable propeller strut structure, the electric tyre hoist is better in maneuverability when running, and the dead weight of the hoist is reduced.

Description

A kind of electric tyre crane

Technical field

The present invention relates to a kind of hoisting crane, relate in particular to a kind of electric tyre crane.

Background technology

The principal feature of wheel-mounted crane is: its go operator's compartment and the lifting control cabin unites two into one, be to develop by crawler crane (crawler crane) to form; The crawler belt and the mobile roof support of traveling gear are partly become the chassis that tire is arranged; Overcome the shortcoming that crawler crane (crawler crane) caterpillar block road pavement damages, the speed of going is also fast than crawler crane (crawler crane); Operation is stable, hoisting capacity big, can lift heavy walking in particular range.

Plurality of advantages in view of wheel-mounted crane; It has been widely used in the lift heavy operation in the limited place of miles of relative movement such as goods yard, harbour, building site; Traditional wheel-mounted crane because of rotary column on it and turntable arrange unreasonable, have that volume is big, the shortcoming of manoevreability difference.

Summary of the invention

The object of the present invention is to provide a kind of electric tyre crane, it reduces operating mechanism's occupation space through the improvement to last rotary column and operating mechanism, and manoevreability is good, to solve the problem that electric tyre crane exists in the prior art.

For reaching this purpose, the present invention adopts following technical scheme:

A kind of electric tyre crane, it comprises underframe, the bottom of said underframe is equipped with road wheel and supporting leg; The turntable seat is installed on the top of said underframe, and the turntable of the pedestal rotation that rotates is set on the said turntable seat, arranges swing type mechanism, lifting mechanism, luffing mechanism on the said turntable and goes up rotary column; And a side of said turntable is installed crane arm; The luffing assembly pulley is arranged on the crane arm through last rotary column, and the afterbody of said turntable is provided with balance weight, and said to go up rotary column be removable Shears.

Especially; Said Shears comprises upper bracket and lower bracket; The top of said upper bracket is provided with pulley assembly, and said upper bracket comprises strut on upright top rod and an end and the top rod bonded assembly, and said lower bracket comprises that upright lower link and top and top rod are through pipe link bonded assembly lower supporting rod; The corresponding through hole of offering with the top of lower link and lower supporting rod in the bottom of said top rod and last strut, bearing pin pass through hole and are connected upper bracket and lower bracket are dismountable.

Especially; Said lifting mechanism comprises electrical motor, speed reduction gearing, coupler and reel; Said electrical motor is connected with speed reduction gearing through coupler, and said speed reduction gearing connects reel, with respect to the opposite side that connects reel drg is installed on the said speed reduction gearing.

Beneficial effect of the present invention does; Compared with prior art the luffing mechanism of said electric tyre crane, lifting mechanism and rotating mechanism are arranged on the turntable; Go up simultaneously rotary column and adopt dismountable Shears form; Manoevreability is better in motion not only to make hoisting crane, and has alleviated the deadweight of hoisting crane.

The specific embodiment

Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment.

See also Fig. 1 and shown in Figure 3, in the present embodiment, a kind of electric tyre crane comprises underframe 1; The bottom of said underframe 1 is equipped with road wheel 2 and supporting leg 3; And be provided with anti-skidding supporting leg 4 in a side of underframe 1, and the top of said underframe 1 installs turntable seat 5, and the turntable 6 of pedestal 5 rotations that rotate is set on the said turntable seat 5; Arrange swing type mechanism 14, lifting mechanism, luffing mechanism 9 and removable Shears 7 on the said turntable 6; And a side of said turntable 6 is installed crane arm 13, and luffing assembly pulley 12 is arranged on the crane arm 13 through Shears 7, and balance weight 8 is arranged at the afterbody of said turntable 6; Also cooperate turntable 6 that inclined ladder 10 is set on the said underframe 1, said inclined ladder 10 connects driver's cab 11.

Said lifting mechanism comprises the electrical motor 15 that hoists, the reductor 17 that hoists, coupler and hoisting drum 16; The said electrical motor 15 that hoists is connected with the reductor 17 that hoists through coupler; The said reductor 17 that hoists connects hoisting drum 16, with respect to the opposite side that connects hoisting drum 16 drg 18 is installed on the said reductor 17 that hoists.

Said luffing mechanism 9 comprises luffing electrical motor 20, amplitude-change speed reducer 19, coupler, amplitude-changing drum 21 and rope winding jib 22; Said luffing electrical motor 20 is connected with amplitude-change speed reducer 19 through coupler; Said amplitude-change speed reducer 19 connects amplitude-changing drum 21; And drg 18 is installed on the said amplitude-change speed reducer 19, and said rope winding jib 22 is arranged at a side of amplitude-changing drum 21.

Said Shears 7 comprises upper bracket and lower bracket; The top of said upper bracket is provided with pulley assembly 70; Said upper bracket comprises strut 72 on upright top rod 71 and an end and top rod 71 bonded assemblys; Said lower bracket comprises that upright lower link 73 and top and top rod 73 are through pipe link 76 bonded assembly lower supporting rods 74; The corresponding through hole of offering in top of the bottom of said top rod 71 and last strut 72 and lower link 73 and lower supporting rod 74, bearing pin 75 pass through hole and are connected upper bracket and lower bracket are dismountable.
