Abstract
The utility model discloses a portable hoisting device for subgrade slope construction. The portable hoisting device for the subgrade slope construction comprises a hoisting portion and a transporting portion, wherein the hoisting portion comprises a base plate on which a balance weight, a motor, a self-locking reducer and a main truss are fixedly arranged, the main truss is reinforced on the base plate through pull rods on which three-phase two-direction switches are arranged, the motor is connected with a winch arranged on the main truss through the self-locking reducer, and the transporting portion is a four-wheel plain trolley. The portable hoisting device for the subgrade slope construction has the advantages of being simple in structure and convenient to maintain and can be well applied to subgrade side construction.
Description
Technical field
The utility model relates to pavement construction technical field, particularly a kind of portable lifting means for roadbed side slope construction.
Background technology
In construction of the highway, roadbed side slope will be installed some safeguard procedures, the installation of safeguard procedures generally adopts the form of wheel crane to carry out lifting operation, but because roadbed limit construction surface is large, point is many, and execution conditions are poor, cause construction slowly, and then will take for a long time crane, virtually cause the wasting of resources, improved construction cost.In order to solve the problem of above-mentioned existence, we are necessary to design a kind of lifting means that can construct at roadbed side slope.
Utility model content
The purpose of this utility model is in order to address the above problem, and has designed a kind of portable lifting means for roadbed side slope construction.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of portable lifting means for roadbed side slope construction, comprise lift portion and transport section two parts, described lift portion comprises chassis, on chassis, be installed with counterweight, electrical motor, self-locking speed-down machine and main couple, main couple is reinforced on chassis by pull bar, pull bar is provided with Three-phase switch, and electrical motor is connected with the winch being arranged on main couple by self-locking speed-down machine, described transport section is four-wheel waggon.
The weight of described counterweight is 45-65 kilogram, generally take 50 kilograms as best.
The power of described electrical motor is 1.5KW/H.
The diameter of the front-wheel of described four-wheel waggon is greater than the diameter of trailing wheel.
The portable lifting means for roadbed side slope construction that utilizes the technical solution of the utility model to make, simple in structure, flexible operation, safe and reliable, can well be applicable in roadbed side slope construction; On any roadbed side slope, can move freely and stop, improve operating efficiency, reduce construction cost.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, if Fig. 1 is the structural representation of the portable lifting means for roadbed side slope construction described in the utility model, as shown in the figure, a kind of portable lifting means for roadbed side slope construction, comprise lift portion and transport section two parts, described lift portion comprises chassis 1, on chassis, be installed with counterweight 2, electrical motor 3, self-locking speed-down machine 4 and main couple 5, main couple is reinforced on chassis by pull bar 6, pull bar is provided with Three-phase switch 7, and electrical motor is connected with the winch 10 being arranged on main couple by self-locking speed-down machine, described transport section is four-wheel waggon.Wherein, the weight of described counterweight is 45-65 kilogram; The power of described electrical motor is the diameter that the diameter of the front-wheel 8 of four-wheel waggon described in 1.5KW/H is greater than trailing wheel 9.
In the technical program, lift portion pulsation-free is placed on to the edge of side slope, need gain in weight the counterweight of 50 kilograms in lift portion, the trailing wheel of four-wheel waggon can be according to the ratio of slope change diameter of side slope, and the side slope that is generally 1: 1.5 according to ratio of slope adjusts.Three-phase switch controls motor switch, electrical motor drives winch to lift up and down operation by self-locking speed-down machine, reaches the object of transportation construction material.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection domain of the present utility model.
