Specific embodiment
Reach the technical means and efficacy that predetermined purpose is taken for the present invention is further explained, below in conjunction with attached drawing and reality
Example is applied to a specific embodiment of the invention, structure feature and its effect, detailed description are as follows.
Country's construction site rail row push trolley at present, majority are voluntarily fabricated by each construction project department, in order to
Meets the needs of onsite moving material, but most push trolley do not have automatic brake mechanism.The core technology of the present embodiment exists
In designing a kind of self-actuating brake linkage mechanism structurally reasonable, dismounting is convenient, safe and reliable, existed with solving construction site push trolley
In use process the problems such as generally existing dismounting inconvenience, Lack of support, track car slipping, the novel normally closed braking rail row is small flat
Vehicle is practical, has wide application value in railway construction construction industry.
As depicted in figs. 1 and 2, the normally closed braking rail row push trolley of the present embodiment includes that vehicle frame 1 and traveling wheel assembly 2 weld
It is integrated, two sides vehicle frame is integral by 3 groups of quick release connecting rod；It is integrated with drum brakes in traveling wheel assembly 2, is arranged
For normally closed mode；Linkage brake mechanism is made of brake connecting rod 7, spring 13, drum brake driving lever 15；The pull rod of 7 one end of brake connecting rod
First 16 and the second braking hilt 17, third bolt 18, the second support 19 form a kind of articulated manner, 6 He of drawhead of the other end
First braking hilt 4, the first support 5 form a kind of articulated manner；8/ second handrail of drawhead 6, drawhead 16 and the first handrail
Bidirectional push rod traveling and braking function are realized in connection.
Drum brake built in traveling wheel assembly 2 is set as normally closed mode, and 13 one end of spring is stopped by spring stop 12, passes through tune
Whole nut 14, to 13 precommpression of spring, while spring 13 provides opposition to brake connecting rod 7, and connecting rod 7 makes drum brake driving lever 15
Rotation makes the brake of the same side travelling wheel keep normally closed mode, realizes that brake is locked.
Two-way linkage push rod traveling principle are as follows: when pushing the first 8/ second handrail of handrail, drawhead 6 and drawhead 16 are transported
Dynamic direction is consistent, while 13 elastic force of spring being overcome to do work, and rotates drum brake driving lever 15, resets brake shoes, realizes brake solution
Lock.
Two-way linkage pushrods parking principle are as follows: when unclamping the first 8/ second handrail of handrail, drawhead 6 and drawhead 16 are transported
Move it is contrary, while 13 elastic force of spring discharge, make drum brake driving lever 15 withdraw, heave brake shoes, realize brake stop.
Bidirectional push rod traveling function is drawhead 6 and 16 side of moving of drawhead when pushing the first 8/ second handrail of handrail
To consistent, while 13 elastic force of spring being overcome to do work, rotate drum brake driving lever 15, reset brake shoes, realizes brake unlock.When
When unclamping the first 8/ second handrail of handrail, drawhead 6 and 16 direction of motion of drawhead are on the contrary, 13 elastic force of spring release simultaneously, makes
Drum brake driving lever 15 is withdrawn, and heaves brake shoes, realizes that brake is stopped.
Linkage brake mechanism has the function of brake-force control, when brake force needs to adjust, by adjusting nut 14, to bullet
Spring 13 applies bigger pressure, so that brake connecting rod 7 is driven the variation of 15 rotational angle of drum brake driving lever, while making brake shoes open-angle
Degree changes, and realizes brake-force control function；When brake shoes abrasion leads to brake force deficiency, by adjusting nut 9, make
10 displacement of guide ring increases, while changes brake shoes opening angle, realizes the adjusting of brake force, brake connecting rod is by outer diameter
The screw rod of M16 is constituted, and is connected by connector sleeve 11.
The linkage brake mechanism of 8 two sides of bidirectional push rod is connected by 8/ second handrail of the first handrail, realizes that two sides brake is total
At synchronizing, locked or unlock, drum brakes wheel set are as shown in Figure 3.
The present embodiment devises drum brakes structure in travelling wheel, and realizes synchronizing unlocking and braking by threaded rod
Function.Brake shoes keeps normally closed mode, and the brake assembly of the same side realizes synchronization action, linkage brake machine by linkage mechanism
Structure both ends form various forms of articulated manners with vehicle frame respectively, realize bidirectional push rod traveling function, when the first handrail 8/ of release
When the second handrail, it is just able to achieve timely braking function.
The vehicle frame and traveling wheel assembly of the present embodiment are welded as a whole, and two sides vehicle frame is by being detachably connected bar composition one
Body is, it can be achieved that convenient dismounting.
The traveling wheel assembly of the present embodiment, built-in drum brake are set as normally closed mode, and spring one end is stopped by spring stop,
Precommpression is carried out to spring by adjusting nut, so that connecting rod is driven the rotation of drum brake driving lever, keeps the brake of the same side travelling wheel
Normally closed mode realizes that linkage brake is locked.
The linkage brake mechanism of the present embodiment has the function of brake-force control.When brake force needs to adjust, pass through adjusting
Nut applies bigger pressure to spring, acts brake connecting rod, drives the rotation of drum brake driving lever, sends out brake shoes opening angle
Changing realizes brake-force control function；When brake shoes abrasion leads to brake force deficiency, guide ring is made by adjusting nut
Displacement increases, while changes brake shoes opening angle, realizes the adjusting of brake force.
Brake connecting rod is made of screw rod, and the bidirectional push rod traveling function being connected by connector sleeve, the linkage brake of two sides
Mechanism is connected by 8/ second handrail of the first handrail, realizes the synchronous braking of two sides brake assembly or unlock.
The present embodiment has the advantage that compared with prior art
1, the present embodiment is structurally reasonable, dismounts convenient, safe and reliable；2, the present embodiment braking mechanism is sensitive reliable, system
Power can be adjusted according to the gradient and bearing capacity needs；3, the present embodiment devises self-actuating brake linkage mechanism, drum brakes
It is set as normally closed, therefore as long as no external force, can realize automatic brake functions, just be able to achieve traveling when pushing connecting rod；
4, the cost of implementation of the present embodiment is low, and braking effect is reliable, convenient for promoting the use of.
It is structurally reasonable, dismounting is convenient, safe and reliable in conclusion a kind of normally closed braking rail row push trolley of the present embodiment,
The brake force of automatic brake mechanism can need to be adjusted according to construction, practical, convenient for promoting the use of.
There are four independent traveling wheel assembly, the brakes of travelling wheel to be set as the normally closed braking rail row push trolley of the present embodiment
Normally closed mode, the same side traveling wheel assembly and Frame Welding are integrated, by self-actuating brake linkage mechanism realize synchronization action, two
Side vehicle frame is integral by dismountable connecting rod group, and brake can be achieved by the promotion and release of 8/ second handrail of the first handrail
The synchronization action of mechanism.Self-actuating brake linkage mechanism shows through the nut between spin brake connecting rod and drum brake driving lever, can be right
