Description

Technical Field

[0001] This utility model relates to grabs, specifically, to a grab body positioning fixture. Background Technology

[0002] A grab bucket is a loading and unloading machine that uses the opening and closing of jaw plates to grab and transport bulk or block materials. According to the driving method, it can be divided into three categories: mechanical, hydraulic and electric.

[0003] For example, patent CN220998953U discloses a double-lobed grab bucket structure, including a bottom plate, fan-shaped end plates disposed at both ends of the bottom plate, and a connecting rod connecting the upper ends of the two end plates; the rear end of the bottom plate rises to form a lower guard plate, and the lower guard plate, end plates, and bottom plate cooperate to form a loading space; two symmetrically arranged first hinge plates are fixedly sleeved on the connecting rod, and the upper end of the first hinge plates is provided with a first pin hole; a second hinge plate is disposed on one side of the two first hinge plates facing each other and is fixedly connected to the bottom plate, and the second hinge plate is provided with a second pin hole penetrating the first hinge plate; the lower end of the first hinge plate extends to the bottom plate and divides the loading space into side spaces disposed at both ends and a central space disposed in the middle.

[0004] When assembling the double-lobed grab bucket structure, the positions of the two middle first hinge plates (i.e. stiffeners) need to be determined first, and then the outer bottom plate and fan-shaped end plate are assembled. The current method is to manually determine the position of the stiffeners by using a dummy shaft, and then assemble the bottom plate and fan-shaped end plate. Under this operation, not only is the position of the stiffeners greatly deviated, but the manpower consumption is also high. Utility Model Content

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0026] See Figure 1-4 The bucket positioning fixture shown includes two positioning beams symmetrically arranged on the left and right sides, which are fixedly connected by multiple connecting beams. The positioning beams include a horizontal beam 1 located in the middle and inclined beams 2 connected to both ends of the horizontal beam 1. The inclined beams 2 at both ends are symmetrically arranged front and back. The two ends of the horizontal beam 1 are symmetrically provided with first bearing seats. The outer ends of the inclined beams 2 are fixedly connected with fixed seats 7. The ends of the fixed seats 7 are provided with second bearing seats. The first bearing seats are equipped with first bearing caps 5 by first bolts 20, and the second bearing seats are equipped with second bearing caps 6 by second bolts 18.

[0027] Through the implementation of the above technical solution, the bucket positioning fixture can position the four stiffening plates 14 in the bucket. After positioning, the four stiffening plates 14 are symmetrically arranged from left to right, forming a shape similar to a grab bucket. After fixing the position of the four stiffening plates 14, it is convenient to splice and weld the bucket body. One person can complete the assembly and welding of the bucket body. Moreover, the assembled and welded bucket body is accurate in size with small deviation, which can also improve the overall strength of the bucket body. At the same time, it also reduces manpower consumption.

[0028] See Figure 5 The shown stiffener 14 has four curved hooks. Each stiffener 14 has a first pivot 21 at its upper end for hinged connection when the grab bucket opens and closes. Each stiffener 14 has a second pivot 22 at its outer protruding part for hinged connection with the swing arm that drives the grab hook to open and close.

[0029] In this invention, the first bearing seat is installed and positioned corresponding to the first rotating shaft 21, and the first bearing cover 5, which is installed on the first rotating shaft 21 by the first bolt 20, is closed and limited to the upper limit of the first bearing seat. In this invention, the second bearing seat is installed and positioned corresponding to the second rotating shaft 22, and the second bearing cover 6, which is installed on the second rotating shaft 22 by the second bolt 18, is closed and limited to the upper limit of the second bearing seat. Each stiffening plate 14 is positioned at least corresponding to the first bearing seat and the second bearing seat.

[0030] In this embodiment, a fixing plate 16 is connected to the outer side of the horizontal beam 1 via a fixing block 15. A third bearing seat coaxial with the first bearing seat is provided on the fixing plate 16. A third bearing cover 19 is installed on the third bearing seat via a third bolt 17. When the middle part of the first rotating shaft 21 is a fixed part and both ends are rotating connecting parts, in order to maintain stability, one end of the first rotating shaft 21 needs to be limited by the first bearing seat and the other end needs to be limited by the third bearing seat, and the position needs to be fixed by the third bearing cover 19.

[0031] In this embodiment, a horizontal plate 3 is provided on the inner side of the horizontal beam 1, and an inclined plate 4 is provided on the inner side of the inclined beam 2. The two ends of the horizontal plate 3 are connected to the corresponding inclined plates 4. Through this arrangement, the overall strength and stability are increased by the vertical connection between the horizontal plate 3 and the horizontal beam 1, and the vertical connection between the inclined plate 4 and the inclined beam 2.

[0032] In this embodiment, the connecting beam includes a main beam 10 connecting the horizontal beams 1, a secondary beam 9 connecting the inclined beams 2, and a reinforcing beam 8 connecting the fixed bases 7. This arrangement further increases the overall structural strength. The main beam 10 can also be welded and fixed to the horizontal plate 3, and the secondary beam 9 and reinforcing beam 8 can be welded and fixed to the inclined plate 4.

[0033] In this embodiment, a connecting lug 13 is fixedly connected to the outer edge of the inclined beam 2. The arrangement of multiple connecting lugs 13 facilitates the connection between the bucket positioning fixture and the fixture table via bolts.

[0034] In this embodiment, the bucket positioning fixture further includes a main positioning rod 11 that passes through the first shaft hole on the end rib plates 14. The bucket positioning fixture also includes a secondary positioning rod 12 that passes through the second shaft hole on the end rib plates 14. The main positioning rod 11 and the secondary positioning rod 12 achieve positioning, and their ends are fixedly connected to the bucket shell, avoiding the traditional method of manually inserting a false shaft and saving manpower.

[0035] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0037] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
