Abstract
The utility model relates to a device for assembly and disassembly of an excavator crawler connecting pin, which comprises a hydraulic controller, an arched body, a crawler pin, a crawler pin fixing sleeve and a press cylinder. The arched body serves as a main component, the whole structure of the arched body is of an arched shape, one end of the arched body is provided with the hydraulic controller, the other end of the arched body is provided with the press cylinder, one end of the middle part of the arched body is provided with the crawler pin fixing sleeve and is parallel to the crawler pin fixing sleeve, and the other end of the middle part of the arched body is provided with the crawler pin. The utility model has the advantages of simple overall structure, convenient use, high safety and high production efficiency. Due to the large, stable and adjustable action of the hydraulic cylinder, the utility model can realize the crawler assembly on the production line and the field removal for maintenance, and the crawler connecting pin can be installed or removed safely and smoothly without damage to the crawler connecting pin and the pin sleeve. Therefore, the utility model not only realizes the assembly and disassembly during production, but also can be removed for maintenance on the field site.
Description
Technical field:
The utility model relates to the engineering machinery auxiliary equipment, relates in particular to excavator crawler belt connecting pin attaching/detaching apparatus.
Background technology:
Hydraulic crawler excavator mostly is a crawler travel now, for needs are installed, does not connect into ring during the crawler belt supply of material, and connecting pin will be installed in the scene.Be interference fit between track pin and pin-and-hole, need very big pressure assembling force during installation, in general, 20 tons of excavator track pins are installed are press-fited and need 40 tons, 65 tons of excavator track pins are installed are press-fited and need 75 tons, now enterprise adopts the hammering installation more.But because the crawler belt position is low, connecting pin is hidden by creeper tread, often occurs track pin is fractureed, riveter, beats and phenomenon such as fly, and the maintenance and repair dismounting in the use is difficult especially.
The utility model content:
The purpose of this utility model is, overcome the deficiencies in the prior art part, solve traditional crawler belt connecting pin and manually use the hammering dismounting, can cause that track pin fractures, riveter, beat and fly, drawbacks such as inefficiency provide a kind of excavator crawler belt connecting pin attaching/detaching apparatus, not only can be safe and reliable the crawler belt connecting pin is installed at production line, and in the open air working site safety, carry out dismounting reliably, efficient, safety.
Excavator crawler belt connecting pin attaching/detaching apparatus described in the utility model includes hydraulic control device, toxoplasm, track pin, track pin fixed cover and press-fits oil cylinder and forms.Said toxoplasm is a main component of the present utility model, and integral body is arc form, at a said toxoplasmatic end, is provided with hydraulic control device, at the said toxoplasmatic other end, is provided with and press-fits oil cylinder.In the middle of said toxoplasm, be provided with the track pin fixed cover by an end, parallel with said track pin fixed cover, also be the other end in the middle of toxoplasm, be provided with track pin.The utility model winches to the track pin place that needs installation with the pad device with instrument, track pin is placed in the track pin fixed cover of device, the primer fluid pressure control device, with press-fiting oil cylinder bearing pin is pressed in the guide reposefully, is pressed into power, press-in speed can be adjusted according to the requirement of different crawler belts.According to different crawler belts the bearing pin of removing is put into the track pin fixed cover during dismounting, be noted herein that the pin diameter that desire is removed should be slightly less than the crawler belt bearing pin, the primer fluid pressing system press-fits oil cylinder promotion dismounting bearing pin track pin is released from connect guide stably.
Excavator crawler belt connecting pin attaching/detaching apparatus described in the utility model, overall structure is simple, and is easy to use, and security is good, the production efficiency height.The utility model is to utilize the big steadily adjustable characteristics of hydraulic jack active force, can realize on the production line of crawler belt that assembling connects and on-the-spot dismounting is safeguarded, crawler belt connecting pin safety and steady ground can be installed or removed, can not cause the damage of crawler belt connecting pin and guide, dismounting in both can having realized producing, dismounting is safeguarded in the working site in the open air again.
Description of drawings:
Accompanying drawing 1 is the structural representation of excavator crawler belt connecting pin attaching/detaching apparatus described in the utility model.1-hydraulic control device 2-toxoplasm 3-track pin 4-track pin fixed cover 5-press-fits oil cylinder
The specific embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: excavator crawler belt connecting pin attaching/detaching apparatus described in the utility model includes hydraulic control device 1, toxoplasm 2, track pin 3, track pin fixed cover 4 and press-fits oil cylinder 5 and forms.Said toxoplasm 2 is main components of the present utility model, and integral body is arc form, and the end at said toxoplasm 2 is provided with hydraulic control device 1, at the other end of said toxoplasm 2, is provided with and press-fits oil cylinder 5.In the middle of said toxoplasm 2, be provided with track pin fixed cover 4 by an end, parallel with said track pin fixed cover 4, also be the other end in the middle of toxoplasm 2, be provided with track pin 3.The utility model winches to the track pin place that needs installation with the pad device with instrument, track pin 3 is placed in the track pin fixed cover 4 of device, primer fluid pressure control device 1, with press-fiting oil cylinder 5 bearing pin is pressed in the guide reposefully, is pressed into power, press-in speed can be adjusted according to the requirement of different crawler belts.According to different crawler belts the bearing pin of removing is put into track pin fixed cover 4 during dismounting, here should note, the pin diameter that desire is removed should be slightly less than the crawler belt bearing pin, and the primer fluid pressing system press-fits oil cylinder 5 promotion dismounting bearing pins track pin is released from connect guide stably.Excavator crawler belt connecting pin attaching/detaching apparatus described in the utility model, overall structure is simple, and is easy to use, and security is good, the production efficiency height.The utility model is to utilize the big steadily adjustable characteristics of hydraulic jack active force, can realize on the production line of crawler belt that assembling connects and on-the-spot dismounting is safeguarded, crawler belt connecting pin safety and steady ground can be installed or removed, can not cause the damage of crawler belt connecting pin and guide, dismounting in both can having realized producing, dismounting is safeguarded in the working site in the open air again.
