Description
Technical Field
The utility model relates to a grab bucket of snatching futilely scattered goods, concretely relates to grab bucket that angle and jaw insertion depth are steerable to be adjusted to jaw plate open. Belongs to the technical field of machine manufacturing.
Background
The grab bucket is a special tool for grabbing bulk cargos by a crane, and is an object containing space formed by two or more openable bucket-shaped jaws, wherein the jaws are closed in a material pile when grabbing the bulk cargos, the bulk cargos are grabbed into the object containing space, the jaws are opened in a suspended state above the material pile when unloading the bulk cargos, and the bulk cargos are scattered on the material pile. The jaw plate of traditional grab bucket opens and shuts and is realized through hoist pulley mechanism lift, has jaw plate opening angle to be difficult to control, sometimes too big surpasss needs, sometimes too little can not reach the requirement, often needs to carry out repetitious operation, and secondly the degree of depth that the jaw plate inserted the material is not fully satisfactory, and the material volume of grabbing is few inefficiency.
Disclosure of Invention
The utility model provides a grab bucket through setting up location shoulder and gravity stone roller, the opening angle of control jaw board and the degree of depth of inserting the material.
The utility model discloses a following technical scheme implements: a grab bucket comprises two crank-slider mechanisms and a winch, wherein the two crank-slider mechanisms comprise two supporting slide bars, a slider, four connecting rods and two jaws, the winch is fixed on the slider and drives the two jaws to respectively rotate around a hinge shaft between the jaws and the supporting slide bars in the forward and reverse directions through a steel wire rope to realize opening and closing; the method is characterized in that:
a positioning shoulder is arranged on the supporting sliding rod, and the positioning shoulder controls the maximum opening angle of the jaw plate by controlling the maximum height of the sliding block;
the position of the positioning shoulder on the supporting slide rod is adjustable;
a gravity weight is arranged on the hinge shaft and controls the depth of the jaw plate inserted into the material;
the weight of the gravity weight can be increased or decreased.
Preferably, the positioning shoulder is connected with the sliding rod through threads, and the position of the positioning shoulder on the supporting sliding rod is adjusted through rotation of the positioning shoulder.
Furthermore, the gravity rollers are arranged in a plurality of numbers, and the depth of the jaw plate inserted into the material is adjusted by increasing or decreasing the number of the gravity rollers.
The unstable and inserting the material degree of depth of opening of jaw angle to traditional grab bucket can not reach the requirement, the utility model discloses set up location shoulder and gravity stone roller respectively on supporting slide bar and hinge pin, overcome the defect of traditional grab bucket, promoted grab bucket work efficiency and stability. The design has the advantages of stable working process, high working efficiency and the like.

FIG. 1 is a schematic structural view of the grab in an open state;
FIG. 2 is a left side view structural schematic diagram of the grab bucket in an open state;
fig. 3 is a front view structure schematic diagram of the closed state of the grab bucket.
In the attached drawing, 1 is a left jaw plate, 1 'is a right jaw plate, 2 is a left connecting rod, 2' is a right connecting rod, 3 is a sliding block, 4 and 4 'are supporting sliding rods, 401 is a positioning shoulder, 5 is a sling, 6 is a winch, 7 and 7' are gravity weights, and 8 is a connecting component.
Detailed Description
The invention will be further explained with reference to the following drawings:
as shown in attached figures 1, 2 and 3, a left jaw plate 1, two left connecting rods 2, a sliding block 3 and a supporting sliding rod 4 form a left crank sliding block mechanism of the grab bucket; the right jaw plate 1 ', two right connecting rods 2' (one of the right connecting rods 2 'is not shown in the figure), a sliding block 3 and a supporting sliding rod 4' form a right crank sliding block mechanism of the grab bucket. A same hinge shaft is arranged between the left jaw plate 1 and the supporting slide bar 4, and between the right jaw plate 1 'and the supporting slide bar 4', and a connecting member 8 is fixed on the hinge shaft; the winch 6 is installed on the sliding block 3, one end of the traction rope is tied to the connecting component 8, the winch 6 tensions the traction rope, the connecting component 8 drives the supporting slide rod 4 and the supporting slide rod 4 ' to slide upwards along the sliding block 3 and respectively drives the left jaw plate 1 and the right jaw plate 1 ' to rotate anticlockwise and clockwise around the hinge shaft, and the left jaw plate 1 and the right jaw plate 1 ' are closed to grab bulk materials; the winch 6 loosens the traction rope, the support slide bar 4 and the support slide bar 4 ' slide downwards along the slide block 3 under the action of the gravity of the connecting member 8, and the left jaw plate 1 and the right jaw plate 1 ' are respectively driven to rotate clockwise and anticlockwise around the hinge shaft, so that the left jaw plate 1 and the right jaw plate 1 ' are reversely opened; the sling 5 drives the grab bucket to ascend or descend, move left or right, and move forward or backward.
The utility model discloses set up location shoulder 401 respectively on supporting slide bar 4 and supporting slide bar 4 ', when left jaw 1 and right jaw 1 ' reverse opening makes location shoulder 401 touch the upper end of slider 3 promptly, then the opening angle between left jaw 1 and the right jaw 1 ' is the biggest.
The utility model discloses fixed set up appropriate gravity stone roller 7 and 7 'on connecting elements, can make left jaw 1 and right jaw 1' insert the stockpile to appropriate degree of depth.
