Abstract

The invention discloses a brake retaining device of an electric sweeper, which comprises a bracket, a long foot bar, a short foot bar, a spring and an inhaul cable. A right end of the long foot bar is connected with the inhaul cable, and the long foot bar is hinged with the bracket through a pin to form a lever type brake mechanism. The short foot bar is installed on the long foot bar through a mandrel and a hinge pin, the downside of the short foot bar is provided with a ratchet to mesh with a fan-shaped ratchet wheel raised on the long foot bar; and the short foot bar of a cantilever keeps the position under the action of the inhaul cable and locks the long foot bar, therefore the purpose of parking after brake is realized. The integrative installing structure of the long foot bar and the short foot bar is located in the same one foot control scale, when the long foot bar is stepped to carry out the brake, the short foot bar also can be stepped; the brake retaining device is convenient to operate, good in timeliness, likely to lock, and stable and reliable in parking. The invention is applicable to be matched with various sized sweepers as well as ordinary locomotives.

Description

Electric sweeper braking holding device

Technical field

The present invention relates to a kind of mechanical position limitation structure, specifically, the present invention relates to a kind of electric sweeper braking holding device.

Background technology

In the electric sweeper operation process, the staff is ordinary affair according to road conditions do temporary parking, makes first skidding under regular situation before the temporary parking, then does the Parking operation.Parking device is a kind of special-purpose machinery position limiting structure that keeps vehicle to be in the brake situation, avoids the rear generation car accident out of control of getting off because of the staff.Parking device and discrete two places of brake gear of the configuration of existing goods electric sweeper, respectively operation on the market.Although the Parking of prior art is simple in structure, keep brake reliable, each operation all need be used both hands and feet, and the operation promptness is poor, and harmony is bad, does not mate with modern sweeper.

Summary of the invention

The present invention proposes a kind of simple in structure, easy and simple to handle, the reliable electric sweeper braking of Parking holding device mainly for the deficiencies in the prior art.

The present invention is achieved through the following technical solutions technical goal.

Electric sweeper braking holding device, it comprises support, long treadle, short treadle, spring and drag-line.Described support is double-deck vertically-arranged rectangular frame, between two-layer parallel alternate plate face, be hinged the long treadle of insertion by pin, the drag-line of long treadle right-hand member head and frame bottom is hinged, and forms the braking mechanism of the lever control drag-line action take pin as fulcrum.Its improvements are: chimb is provided with and take the center, hole of location and installation pin as the fan-shaped ratchet in the center of circle on the described long treadle right-hand member.Described short treadle right-hand member is provided with two through holes, short treadle is inserted in the support and is positioned on the long treadle, it is hinged with the equipped mandrel of right-hand member through hole and support assorted, middle through-hole inserts spacing being slidingly matched of arc track groove of presetting on bearing pin and the support two plate faces, mandrel, meshing point and pin be position Triangle-Profile in obtuse angle on support, meshing point is in the drift angle of obtuse triangle, right section bottom of short treadle is between the hole that mandrel and bearing pin are installed, be provided with the fan-shaped ratchet engagement of an evagination ratchet and long treadle, long treadle is pinned in the short treadle of cantilever holding position under the effect of drag-line.

The said structure medi-spring is torque spring, and the center of circle of arc track groove is the through hole center of the equipped mandrel of short treadle.

The present invention compared with prior art has following good effect:

1, long treadle and short treadle integrative installation technology are simple in structure, make easily;

2, long treadle and short treadle are in the control range of same pin position, step to attach when long treadle is implemented skidding to step short treadle, and simple operation, promptness is good;

3, the ratchet on the short treadle is reliable with the fan-shaped ratchet engagement on the long treadle, and lock-bit is easy, the Parking good stability.

Description of drawings

Fig. 1 is structural profile schematic diagram of the present invention, is illustrated as conventional transport condition.

Fig. 2 is after long treadle and short treadle order steps downwards among Fig. 1, and short treadle pins long treadle maintenance skidding.

Fig. 3 is that short treadle resetted in the effect of spring, loses the restriction to long treadle after long treadle further stepped among Fig. 2.

Fig. 4 is the top view of Fig. 1.

Fig. 5 is A place partial structurtes enlarged diagram among Fig. 4.

The specific embodiment

The invention will be further described with reference to the accompanying drawings for the below.

Electric motor car sweeper braking holding device shown in Figure 1, it comprises support 1, long treadle 2, short treadle 3, spring 4 and drag-line 5.Described support 1 is double-deck vertically-arranged rectangular frame, between two-layer parallel alternate plate face, be hinged the long treadle 2 of insertion by pin 2.1, the long drag-line 5 of stepping on right-hand member head and support 1 bottom is hinged, and forms the braking mechanism of the lever control drag-line action take pin 2.1 as fulcrum.Chimb is provided with fan-shaped ratchet on long treadle 2 right-hand members among the present invention, and the center of circle of fan-shaped ratchet is positioned at the center, hole of location and installation pin 2.1 on the long treadle 2.Described short treadle 3 right-hand members are provided with two through holes, and short treadle 3 is inserted in the support 1 and is positioned on the long treadle 2, and it cooperates with support 1 with the equipped mandrel 1.2 of right-hand member through hole and is hinged.Middle through-hole inserts the arc track groove 1.1 that presets on bearing pin 3.1 and 1 liang of plate face of support and is slidingly matched, and the center of circle of arc track groove 1.1 is through hole centers of short treadle 3 equipped mandrels 1.2.Mandrel 1.2, meshing point 2.2 and pin 2.1 position Triangle-Profile in obtuse angle on support 1 among the present invention, meshing point 2.2 is in the drift angle of obtuse triangle, the position stability of the relatively long treadle 2 of the short-and-medium treadle 3 of this structure.3 right sections bottoms of short treadle are provided with the fan-shaped ratchet engagement of an evagination ratchet and long treadle 2 between the hole that mandrel 1.2 and bearing pin 3.1 are installed, long treadle 2 is pinned in the short treadle 3 of cantilever holding position under the effect of drag-line 5.

When sweeper normally travels as shown in Figure 1, long treadle 2 and short treadle 3 are in horizontal, bearing pin 3.1 spacing arc track groove 1.1 upper ends on support 1 that short treadle 3 is equipped with, the leftmost ratchet of fan-shaped ratchet on the short treadle 3 on ratchet and the long treadle 2 is in released state.Temporary parking or stop in emergency as shown in Figure 2, depress first long treadle 2 brakings, then depress in passing the application position that short treadle 3 pins long treadle 2 after the brake, the ratchet engagement of short treadle 3 is on long treadle 2 rightmost ratchets, short treadle 3 holding positions are motionless under drag-line 5 effects, realize the Parking purpose behind the skidding, and the staff is got off still can keep reliable Parking, safe Parking.The recovery front Parking control cancelled first of travelling, long treadle 2 shown in Figure 3 is gently stepped on again, makes under torque spring 4 acts on that bullet is reset to horizontal level on the short treadle 3, loses the restriction of long treadle 2 is resetted.

Long treadle 2 and short treadle 3 integrated mounting structures among the present invention are in the control range of same pin position, step to attach when long treadle 2 is implemented skidding to step short treadle 3, and simple operation, promptness is good, pins easily, and Parking is reliable and stable.
