Abstract
The invention discloses a rear frame of a loader and relates to the technical field of engineering machinery. The rear frame comprises a left web and a right web. The left web is composed of a left front web section and a left rear web section. The right web is composed of a right front web section and a right rear web section. A left balance weight and a right balance weight are arranged on the outer side of the left rear web section and the outer side of the right rear web section respectively. The left front web section and the right front web section are both a welding part of a box type structure. The left rear web section and the right rear web section are both an integral solid part. Compared with the prior art, the strength of the left rear web section and the right rear web section is better, no rib plates need to be additionally arranged on the side face of the left rear web section and the side face of the right rear web section, installing space is saved, the left balance weight and the right balance weight are easily installed, and the left rear web section and the right rear web section further achieve the effects of the balance weights. The length sizes of the left front web section and the right front web section are small, the welding workload is reduced, time and labor are saved, and production efficiency is improved.
Description
Technical field
The present invention relates to technical field of engineering machinery, especially a kind of Rear frame of loader.
Background technology
The Rear frame of loader is mainly used in installing driver's cabin and electromotor, and the material of large-scale loading mechanical shovel dress is many, is
Prevent the loader from tumbling, also need to increase counterweight in the afterbody of Rear frame.The Rear frame of loader using at present includes left abdomen
Plate and right web, the front portion of left web and right web is connected by hinged seat, and rear portion is connected by tailgate and forms framework, on a left side
The front portion of web and right web is provided with driver's cabin erection support, and rear portion is provided with engine-mounting bracket, and left web and right web are equal
Weldment for box-structure；The left web of box-structure and right web are all by two blocks of side plates being oppositely arranged and to connect two pieces
The polylith seal plate welding at side plate edge forms.Because the length dimension of left web and right web is big, part is many, complex structure, whole
Body intensity is not enough, is easily deformed, needs repeatedly to adjust correction in welding process, also will increase a lot of plates to ensure in its side
Intensity, the workload of welding is big, time-consuming；And these plates take very big space, lead to counterweight difficulty is installed.
Content of the invention
The technical problem to be solved is to provide a kind of Rear frame of loader, can solve existing loader rear car
The workload of the left web of frame and the welding of right web is big, time-consuming, and installs the difficult problem of counterweight.
In order to solve the above problems, the technical solution used in the present invention is：This Rear frame of loader, includes left web
With right web, described left web is made up of left front web section and left back web section, after described right web is by right leading web section and the right side
Web section forms, and is respectively provided with left counterweight and right counterweight in the outside of described left back web section and described right trailing web section；Described
Left front web section and described right leading web section are weldment, described left back web section and the described right trailing web section of box-structure
It is overall solid member.
In above-mentioned Rear frame of loader technical scheme, more specifically technical scheme can also be：Described left front web section and
The rear end of described right leading web section is respectively equipped with stopper slot, and the front end of described left back web section and described right trailing web section sets respectively
There is the positive stop lug boss matching with the stopper slot of described left front web section and described right leading web section.
Further, the material of described left back web section and described right trailing web section is steel plate or cast steel.
Due to employing technique scheme, the present invention compared with prior art has the advantages that：
1st, the left web of the present invention is made up of left front web section and left back web section, and right web is by right leading web section and right trailing web
Duan Zucheng；Left front web section and right leading web section are the weldment of box-structure, and left back web section and right trailing web section are overall
Solid member；The structure of left back web section and right trailing web section is simple, intensity more preferably it is not necessary to after left back web section and the right side abdomen
The side of plate section installs plate additional, saves installing space, installs left counterweight and right counterweight easily, left back web section and right trailing web section
Also act as the effect of counterweight simultaneously；The length dimension of left front web section and right leading web section is little, decreases the workload of welding, saves
Shi Shengli, improve production efficiency.
2nd, the rear end of left front web section and right leading web section is respectively equipped with stopper slot, left back web section and right trailing web section
Front end is respectively equipped with the positive stop lug boss matching with the stopper slot of left front web section and right leading web section；Make left front web section and the right side
Accurate positioning when leading web section is connected with left back web section and right trailing web section respectively.
