Description

TECHNICAL FIELD

[0001] The utility model relates to engineering machinery field especially, and particularly relates to a grab bucket, and specifically is a kind of assembly type connecting support for grab bucket reversing. BACKGROUND

[0002] Grab bucket as the common equipment in engineering machinery, when facing the complex working condition of wall sticking and position intersection in use process, there will be some problems, for example, guiding and positioning difficulty: when grab bucket is closely attached to wall and works, its guiding system can be limited by wall surface, leading to positioning accuracy to drop, and then affect operation efficiency and accuracy;At the same time, due to the intersection position of chassis and wall surface, the bucket body is also crossed with wall surface, so that the collision risk of bucket body and wall surface is increased.

[0003] Usually, in order to solve these problems, additional traction measures such as traction rope are equipped, so that grab bucket is turned into parallel state with wall surface, however, such operation increases the complexity of mast, and also increases the operation difficulty. UTILITY MODEL CONTENT

[0004] The utility model aims at overcoming the above-mentioned defects, and proposes a connecting support capable of rotating grab bucket at a certain angle, by using the support, grab bucket can be quickly, safely and conveniently reversed, so as to overcome the problem of contradiction between chassis position and wall.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized as follows:

[0006] An assembly type connecting support for grab bucket reversing, comprising base, connecting lug plate, connecting pin and pipeline joint;Mounting hole is formed on the chassis, connecting lug plate is used in pairs and is vertically and symmetrically arranged on the base and is connected with the base through mounting hole by bolt, connecting pin is arranged in the connecting lug plate on both sides, and pipeline joint is arranged beside the base, and the pipeline joint is used for connecting external pipeline to grab bucket.

[0007] The assembly type connecting support for grab bucket reversing, mounting hole is arranged in square position on the base, so as to form two cross mounting positions in longitudinal and transverse directions, and connecting lug plate is symmetrically arranged on the base according to different position requirements of grab bucket and is connected with the base through corresponding mounting hole by bolt.

[0008] The assembly type connecting support for grab bucket reversing, reinforcing rib is arranged at the bottom of the base, the reinforcing rib is used for increasing the rigidity of the base, and at the same time, the reinforcing rib is deeply arranged in the bucket frame of grab bucket, and is used for guiding and positioning the whole connecting support.

[0009] The assembly type connecting support for reversing the grab bucket has connecting holes opened in four corners of the base, the whole connecting support is bolted with the top of the grab bucket frame through the connecting holes in the four corners of the base, and the connecting pin of the connecting support is used for connecting the traction rope, so that the grab bucket is lifted up through the connecting support.

[0010] The assembly type connecting support for reversing the grab bucket has connecting ears, a shaft seat is sleeved on the connecting ears, and the connecting pin is arranged in the shaft seat, so that the contact area between the connecting pin and the connecting ears is increased, and stress dispersion is facilitated.

[0011] The above connecting support makes the grab bucket be able to reverse in place, and brings many benefits; for example, in some occasions with limited operation space or complex environment, the traditional reversing mode of the grab bucket through the traction steel wire rope may be limited; and the grab bucket can be more flexibly used in narrow space and the like through the reversing of the connecting support, and a wider operation environment is adapted. Further, multi-direction operation: the design of the reversing support makes the grab bucket be able to operate in different directions, without frequent movement of the equipment position, so that the flexibility and diversity of operation are improved.

[0019] The technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of the present application.

[0020] As Figures 4-5 A kind of assembly type connecting support for grab bucket commutation, including base 1, connecting lug plate 2, connecting pin 3 and pipeline joint 4;Mounting hole 5 is set up on base 1, connecting lug plate 2 is used in pairs and vertically, symmetrically set on base 1 and with base 1 by mounting hole through bolt connection, connecting pin 3 is threaded in two side connecting lug plate 2, pipeline joint 4 is set on the side of base 1, the pipeline joint 4 is used to connect pipeline access grab bucket.
