Abstract

The utility model relates to a micro crane, which can effectively solve the problems that a crane can not safely work in narrow and small space and can not realize remote operating. The technical scheme is as follows: the micro crane comprises a lifting arm, a lifting hook, a hydraulic cylinder and a supporting leg. The crane bracket is provided with a rotary body; the lifting arm and the rolling hydraulic cylinder are respectively fixed on the rotary body through two different shafts; a telescopic rod of the rolling hydraulic cylinder is supported onto the lifting arm; the supporting leg is installed on four corners of the crane bracket by the supporting leg frame in an axisymmetric way; the supporting leg hydraulic cylinder is located onto the supporting leg through two shafts on the supporting leg; the supporting leg is placed on a pedal of the crane bracket in a rotating way when being folded; the lower parts at both sides of the crane bracket are provided with a tension wheel, a walking wheel and a driving wheel through bolts; a caterpillar belt is installed on the crane bracket through the tension wheel, the walking wheel and the driving wheel; the front end of the crane bracket is provided with a gasoline engine; the upper end of the lifting arm is provided with the lifting hook. The micro crane with high lifting capacity, small volume, convenient operation and wireless control has good economical and social benefits.

Description

A kind of miniature crane

One, technical field

The utility model relates to weight-lifting equipment, particularly a kind of miniature crane.

Two, background technology

At present, known crane structure is to be assembled by arm, supporting leg, hydraulic actuating cylinder, oil cylinder, cylinder, suspension hook, joystick, tire or crawler belt.Start oil pressure pump, the power that oil pressure produces makes runnings such as arm, supporting leg by the control of control lever, and hoisting or hoist with lever and assembly pulley principle adds moving heavy object.General crane need move in than the large space scope, and normal and operating personnel's direct contact (as suspension hook, steel rope etc.), potential many accidental danger factor, so the reform of crane is imperative with innovation.

Three, utility model content

At above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model just is to provide a kind of miniature crane, can effectively solve crane and can not can not realize remote operated not enough problem at the small space trouble free service.

The technical solution of the utility model is, the utility model comprises arm, suspension hook, hydraulic actuating cylinder and supporting leg, the cycle body is housed on the vehicle body hanger, arm is fixed on the cycle body by two different axles respectively with the fluctuating hydraulic actuating cylinder, the expansion link upper end of fluctuating hydraulic actuating cylinder is supported on the arm, supporting leg is installed on four jiaos of the vehicle body hanger by the supporting rack rotational symmetry, landing leg hydraulic cylinder by two shaft alignments on the supporting leg on supporting leg, rotation was placed on the pedal of vehicle body hanger when supporting leg was folding, vehicle body hanger two side lower parts are equipped with tension wheel by bolt, road wheel and drive wheel, crawler belt is contained on the vehicle body hanger by tension wheel and road wheel and drive wheel location, the vehicle body hanger front end is equipped with spark ignition engine, drive change speed gear box and oil pump work, suspension hook is equipped with in the arm upper end.Said arm is the extrusome that more piece is formed, and supporting leg is a folded formation, and said tension wheel is Φ 200 inducers, and road wheel is Φ 150 inducers, and drive wheel is that Φ 178 takes turns, and the number of teeth is at least 7; The cycle body is two-way 360 degree rotations; Respectively there is a crawler belt on the vehicle body hanger both sides.

The utility model hydraulic efficiency pressure system oil circuit is succinct, system pressure is little, the crane profile is light and handy, has higher load-carrying ability, even also can carry out operation safely in special places such as narrow space or broken terrains, the miniature crane volume of the utility model is little, handled easily, but wireless remote control in the 50M scope has good economic and social benefit.

Four, description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is a birds-eye view of the present utility model.

Fig. 3 is a lateral plan of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done detailed explanation.

By Fig. 1, Fig. 2, Fig. 3 provides, the utility model comprises arm, suspension hook, hydraulic actuating cylinder and supporting leg, cycle body 3 is housed on the vehicle body hanger 4, arm 1 is fixed on the cycle body 3 by two different axles respectively with fluctuating hydraulic actuating cylinder 11, the expansion link upper end of fluctuating hydraulic actuating cylinder 11 is supported on the arm 1, supporting leg 2 is installed on 4 four jiaos of the vehicle body hanger by the supporting rack rotational symmetry, landing leg hydraulic cylinder 10 by two shaft alignments on the supporting leg 2 on supporting leg 2, rotation was placed on the pedal of vehicle body hanger 4 when supporting leg 2 folded, 4 liang of side lower parts of vehicle body hanger are equipped with tension wheel 5 by bolt, road wheel 6 and drive wheel 7, crawler belt 8 is contained on the vehicle body hanger 4 by tension wheel 5 and road wheel 6 and drive wheel 7 location, vehicle body hanger 4 front ends are equipped with spark ignition engine 9, and suspension hook 12 is equipped with in arm 1 upper end.

In order to guarantee result of use, said arm 1 is the extrusome that more piece is formed, and supporting leg 2 is a folded formation, and said tension wheel 5 is Φ 200 inducers, and road wheel 6 is Φ 150 inducers, and drive wheel 7 is taken turns for Φ 178, and the number of teeth is at least 7; Cycle body 3 is two-way 360 degree rotations; Respectively there is a crawler belt 8 on vehicle body hanger 4 both sides.

By said structure as can be seen, the utility model is when work, spark ignition engine drives change speed gear box and oil pump work, can supporting leg 2 be launched to support on the ground by landing leg hydraulic cylinder 10, constitute stable supporting mechanism, fluctuating hydraulic actuating cylinder 11 can be propped arm 1 or put down, and regulates the arm high and low position, and match with hoisting arm expansion, realize differing heights, different distance hang thing, and realize the operation of different azimuth by cycle body 3, a crawler belt changes a crawler belt when turning is not changeed, profile is light and handy, and load-carrying ability is strong, and the time spent can be not folding with supporting leg, the arm withdrawal, folding being placed on the vehicle body hanger 4, and mobile flexibly on the ground by crawler belt and inducer, even also can carry out operation safely in special places such as narrow space or broken terrains, easy to operate, also can cooperate wireless remote control in case of necessity, realize remote operation in the 50m scope, of the present utility model succeeding in developing, being that one on the crane is big improves and innovation, and good economic and social benefit is arranged.
