Abstract

The utility model discloses a man-powered transportation vehicle with a limit controller in the field of transportation vehicles; the man-powered transportation vehicle comprises a carriage; the front end of the carriage is symmetrically connected with two hand bars; an axle is fixed on the bottom of the carriage; both ends of the axle are provided with wheels through bearings; a ratchet wheel is fixed on the hub of each wheel; a limit mechanism is fixed on the axle; the limit mechanism comprises a shell and a limit tongue; the shell and the axle are fixed; the shell is provided with a slide way with an open end; the limit tongue is inserted from the open end of the slide way into the slide way in a matching way; a reset spring is arranged between the limit tongue and the inner bottom of the slide way; the end of the limit tongue is inserted from the radial direction of the ratchet wheel into the concave cavity of a ratchet; a guy cable connected with the root of the limit tongue goes through the shell and is connected with control handles on the hand bars. When the vehicle works, the end of the limit tongue cooperates with the ratchet, so that the ratchet can only rotate in the same direction which can prevent accidents when the man-powered transportation vehicle slides down in slope climbing, and can be used in transporting building materials on the construction site.

Description

Have the manpower transport vechicle of limit to control setup

Technical field

The utility model relates to a kind of transportation means, particularly a kind of manpower transport vechicle.

Background technology

In the prior art, a kind of manpower transport vechicle is arranged, mainly include the compartment, the compartment front end is symmetrically connected with two handlebars, and the bottom, compartment is fixed with axletree, and there is wheel at the axletree two ends through bearing installation.This device can be used for building ground transportation building materials, has light, advantage flexibly.Its weak point is: the wheel operation of available man-power transport trolley is not limit to function, when meeting specific environments such as upward slope, when promoting application force forward or stop application force less than the regression power of vehicle under specific environment admittedly, the personnel that control are difficult to the control transport vehicle, and various accidents take place easily.

The utility model content

The purpose of this utility model provides a kind of manpower transport vechicle who has limit to control setup, can allow the flexible control vehicle service direction of the personnel of controlling, and avoids the accident that causes because of the vehicle regression.

The purpose of this utility model is achieved in that and has the manpower transport vechicle of limit to control setup, and include the compartment, the compartment front end is symmetrically connected with two handlebars, and the bottom, compartment is fixed with axletree, and there is wheel at the axletree two ends through bearing installation; Be fixed with a ratchet on the wheel hub of wheel, be fixed with a stop gear on the axletree, described stop gear comprises that housing and limit are to tongue, described housing and axletree fix, be provided with the chute of an end opening in the housing, limit cooperates in the insertion chute to the open end of tongue from chute, and limit is provided with retracing spring between the inner bottom part of tongue and chute, described limit, is passed housing with limit to the drag-line that root of the tongue portion links to each other and is linked to each other with control handle on the handlebar along in the recessed limit of radially inserting ratchet of ratchet to the tongue end.

In the utility model when work, can spur limit to tongue by control handle, and the ratchet of limit on tongue end and ratchet is separated, and wheel can free forward rotation like this, but also backward rotation has made things convenient among a small circle to turn to, turn around; When control handle unclamps, under action of reset spring, limit is inserted in the groove of ratchet ratchet to the tongue end, ratchet can only rotate to direction, promptly can only forward rotation, and can not backward rotation, like this, in up gradient, can prevent the downward regression of manpower transport vechicle, can avoid the accident that causes because of regression.Compared with prior art, this device is controlled flexibly, can prevent manpower transport vechicle's regression, can be used for building ground transportation building materials.

For making the manpower transport vechicle can remove the regression restriction, described limit is provided with jack to the tongue side, and correspondence is provided with movable latch on the housing, and when latch inserted jack, the ratchet of limit on tongue end and ratchet was separated.The tension control handle can make bearing pin and jack over against, insert bearing pin in the jack this moment, can make limit be locked in the position that is separated with ratchet to tongue, like this, the manpower transport vechicle can be the same with existing manpower transport vechicle, do not have to move ahead and the restriction of regression.

Description of drawings

Fig. 1 is the utility model integral structure scheme drawing.

Fig. 2 is the utility model local structure scheme drawings.

Wherein, 1 ratchet, 2 wheels, 3 axletrees, 4 compartments, 5 handlebars, 6 drag-lines, 7 control handles, 8 jacks, 9 latches, 10 housings, 11 retracing springs, 12 chutes, 13 limits are to tongue.

The specific embodiment

As Fig. 1 and 2, for having the manpower transport vechicle of limit, include compartment 4 to control setup, compartment 4 front ends are symmetrically connected with two handlebars 5, and 4 bottoms, compartment are fixed with axletree 3, and there is wheel 2 at axletree 3 two ends through bearing installation; Be fixed with a ratchet 1 on the wheel hub of wheel 2, be fixed with a stop gear on the axletree 3, described stop gear comprises that housing 10 and limit are to tongue 13, housing 10 fixes with axletree 3, be provided with the chute 12 of an end opening in the housing 10, limit cooperates in the insertion chute 12 to the open end of tongue 13 from chute 12, limit is provided with retracing spring 11 between the inner bottom part of tongue 13 and chute 12, described limit, is passed housing 10 with limit to the drag-line 6 that tongue 13 roots link to each other and is linked to each other with control handle 7 on the handlebar 5 along in the recessed limit of radially inserting ratchet of ratchet 1 to tongue 13 ends; Limit also is provided with jack 8 to tongue 13 sides, and correspondence is provided with movable latch 9 on the housing 10, and when latch 9 inserted jack 8, the ratchet of limit on tongue 13 ends and ratchet 1 was separated.

During work, can spur limit to tongue by control handle, the ratchet of limit on tongue end and ratchet is separated, wheel can free forward rotation like this, but also backward rotation has made things convenient among a small circle to turn to, turn around; When control handle unclamps, under action of reset spring, limit is inserted in the groove of ratchet ratchet to the tongue end, ratchet can only rotate to direction, promptly can only forward rotation, and can not backward rotation, like this, in up gradient, can prevent the downward regression of manpower transport vechicle, can avoid the accident that causes because of regression.

Claims
