Abstract

A lifting device for a spare wheel of a wheel type crane is characterized by comprising a chassis frame (1), wherein a main arm support frame (2) is installed above the chassis frame (1), a hinged support frame (7) is installed below the chassis frame (1), a hand winch (3) and a pulley support frame (4) are installed on the side face of the main arm support frame (2), the pulley support frame (4) is provided with a fixed pulley (5), and the hinged support frame (7), the hand winch (3) and the pulley support frame (4) are located at the position of a space on the same side. A spare wheel frame (8) which is used for installing the spare wheel (9) is hinged on the hinged support frame (7), and a steel wire rope (6) on the hand winch (3) bypasses the fixed pulley (5) and is connected on the spare wheel frame (8). According to the lifting device, the hand winch has the function of self locking, positive rotation and negative rotation are both safe and reliable, operation is easy, manufacture cost is low, and the lifting device is suitable for the automobile crane, wherein the spare wheel of the automobile crane is located near the main arm support frame.

Description

A kind of wheel crane spare tyre handling device
Technical field
The utility model relates to a kind of hoisting crane spare tyre lifter, particularly relates to a kind of wheel crane spare tyre handling device.
Background technology
Existing wheeled (automobile) hoisting crane spare tyre is installed on the hoisting crane afterbody, spare tyre is lifted or digs, be installed on the fixer with manpower.This mounting means not only exists safety hazard, and time-consuming again effort, and need to provide a kind of does not affect the normal operation of hoisting crane and satisfy that the spare tyre handling makes things convenient for, saves time, labour-saving spare tyre handling device for this reason.
Summary of the invention
The purpose of this utility model provides a kind of just not to be affected the normal operation of hoisting crane and satisfies that the spare tyre handling makes things convenient for, saves time, labour-saving wheel crane spare tyre handling device for existing weak point in the above-mentioned prior art.
The purpose of this utility model can realize by following technique measures:
Wheel crane spare tyre handling device of the present utility model comprises chassis frame, the principal arm support is housed above chassis frame, at the chassis frame side-lower articulated stand is housed, crank capstan is installed in principal arm support side and the pulley bracket of fixed pulley is housed, and described articulated stand and crank capstan and pulley bracket are positioned at locus, the same side; Be hinged with for the spare tyre holder that spare tyre is installed at described articulated stand, the steel rope on the crank capstan is walked around fixed pulley and is connected on the spare tyre holder.
Crank capstan described in the utility model is comprised of the two-stage gear reduction, can realize deciding the reduction ratio gear transmission, and described crank capstan is with auto-lock function, and rotating is all safe and reliable.
Principle of work of the present utility model is as follows:
When adopting hoisting crane spare tyre handling of the present utility model mechanism that spare tyre is installed, by crank capstan is emitted steel rope, spare tyre holder is put on the ground, spare tyre is installed on the spare tyre holder, the steel rope of crank capstan is regained, spare tyre is risen to the pulley bracket below get final product.
The beneficial effects of the utility model are as follows:
Because the utility model is to install hoisting crane spare tyre handling mechanism additional in the situation that do not change former principal arm supporting structure, and this mechanism and other original papers are not also interfered; And crank capstan has larger bearing capacity, can satisfy widely the loading and unloading requirement of hoisting crane spare tyre commonly used.
In sum: the utility model is a kind of saving space, has alleviated the hand labor intensity of hoisting crane spare tyre handling, whole device low cost of manufacture, and the operating process time is short, and loading and unloading are quick, and are safe and reliable.The spare tyre that is applicable to that can be convenient and simple is positioned near the car hosit of principal arm support.
Description of drawings
Fig. 1 is the utility model device schematic diagram.
Fig. 2 is the utility model side schematic view (spare tyre holder is in collapsed state).
The specific embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1 and Figure 2, wheel crane spare tyre handling device of the present utility model comprises chassis frame 1, principal arm support 2 is housed above chassis frame 1, at chassis frame 1 side-lower articulated stand 7 is housed, crank capstan 3 and the pulley bracket 4 that fixed pulley 5 is housed are installed in principal arm support 2 sides, and described articulated stand 7 is positioned at locus, the same side with crank capstan 3 and pulley bracket 4; Be hinged with for the spare tyre holder 8 that spare tyre 9 is installed at described articulated stand 7, the steel rope 6 on the crank capstan 3 is walked around fixed pulley 5 and is connected on the spare tyre holder 8; Described crank capstan is comprised of the two-stage gear reduction, can realize deciding the reduction ratio gear transmission, and described crank capstan is with auto-lock function, and rotating is all safe and reliable.
