Description
Technical field
The utility model relates to a kind of loading-unload machine, a kind of specifically hydraulic grab.
Background technology
We know that grab bucket is the hauling operation instrument that is used for grasping, shifting material.It generally comprises the strut member of suspension ring, skip body, support skip body, and skip body comprises again grabs lobe and transom.At present electronic and mechanical type grab bucket is adopted steel rope to connect and is grabbed lobe, utilizes the rotation of motor to rotate to steel rope in the bead coil and lobe is grabbed in pulling, makes to grab lobe and shrink, stretch.Soft steel rope swings grab bucket easily, when grabbing lobe extracting material, is not easy to downwards firmly, and the extracting dynamics is little, therefore, is difficult for picking up, put down material exactly, and performance is unreliable.In addition, electronic and mechanical type grab bucket complex structure, fault is many, and maintenance is frequent.Rotary hydraulic grab bucket is also arranged at present, and its two jaws are to be the center with the through beam, and are closed in rotary manner, on the side plate of each jaw, install several to tilt cylinder, after high-pressure and hydraulic oil flows into tilt cylinder, the relative rotation of every pair of swing arm will hold up through beam, thereby finish the closure of grab bucket.But the structure of should grabbing bucket is still complicated, and just closed in rotary manner, skip body itself can not rotate, and it is convenient inadequately to manipulate.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, and dependable performance grasps great efforts, and synchronism is good, high efficiency, and can realize the hydraulic grab that arbitrarily angled plane rotates.
The technical scheme in the invention for solving the above technical problem is: a kind of hydraulic grab, it comprises suspension ring, the grab bucket lid, grab lobe, the transom of lobe is grabbed in connection and support, the grab bucket lid is by suspension ring and use mechanical connection, it is characterized in that: grab bucket covers and is provided with hydraulic rotary actuator, the bottom is provided with the rotating disc of band rack rails, the gear of hydraulic rotary actuator and the rack rails of rotating disc cooperate, the driven rotary dish rotates, the rotating disc bottom with grab the lobe transom and be connected and fixed, some lobe upper ends of grabbing are hinged with grabbing the lobe transom respectively, grab and also are connected with its stretching, extension of control and closed hydraulic ram and piston rod on the lobe.The utility model hydraulic ram is positioned at grabs the lobe inboard, and an end is with to grab the lobe transom hinged, other end piston rod with grab the lobe lower hinge.
The utility model can be equipped in that all kinds of fluid pressure types excavate, on the loading-unload machine, utilize the hydraulic efficiency gear of excavating machine etc. itself to do power.Owing to adopt hydraulic power, but grabbing the lobe transom and grab lobe and realize at any angle the plane rotation by hydraulic rotary actuator driven rotary dish and its underpart, realize grabbing the stretching, extension and the closure of lobe by being arranged at the hydraulic ram and the piston rod of grabbing the lobe inboard, thereby the material of finishing grab bucket grasps and transfer tasks.Against existing technologies, the utility model is rational in infrastructure, and dependable performance grasps great efforts, synchronism is good, high efficiency.This grab bucket is without steel rope, is applicable to be installed in that hydraulic crane and all kinds of fluid pressure type excavate, to use on the loading-unload machine.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model grab bucket lid.
Fig. 3 is the structural representation that the utility model is grabbed lobe.
Fig. 4 is the structural representation that the utility model is grabbed the lobe transom.
1. suspension ring among the figure, 2. grab bucket lid is 3. grabbed the lobe transom, 4. grabs lobe, 5. high-pressure oil passage conduit, 6. hydraulic ram, 7. piston rod, 21. hydraulic rotary actuators, 22. rotating discs, 23. gears, 24. rack rails, 31. hinge holes, 32. hinge holes, 41. hinge holes, 42. hinge holes.
The specific embodiment
As can be seen from Figure 1, a kind of hydraulic grab, it comprise suspension ring 1, grab bucket cover 2, grab lobe 4, connect and support grab lobe grab lobe transom 3, grab bucket cover 2 by suspension ring 1 and use mechanical connection, use machinery can be all kinds of fluid pressure type excavations, loader-unloader etc.Suspension ring 1 covers 2 with grab bucket and are connected by pin, and suspension ring 1 can be according to the size design of grab bucket, make it and grab bucket to cover 2 and be complementary.Grabbing lobe transom 33 tops cover 2 rotating disc with grab bucket and is connected a plurality of lobes 4 of grabbing of bottom connection.
It can also be seen that from Fig. 1, Fig. 2 the utility model grab bucket is covered 2 and is provided with hydraulic rotary actuator 21, hydraulic rotary actuator 21 is commercial existing products, which is provided with into and out of high-pressure oil passage, and wherein the import of left rotation and right rotation high pressure oil is 25, and the high pressure oil outlet is 26.The high pressure oil that uses machinery produces rotational force by hydraulic rotary actuator 21.Hydraulic rotary actuator 21 bottoms are provided with a gear 23.Grab bucket and cover the rotating disc 22 that 2 bottoms also are provided with band rack rails 24, gear 23 matches with rotating disc rack rails 24, and driven rotary dish 22 rotates, and then drives the member rotation of its underpart, so just finishes the inner spinfunction of grab bucket.That is to say that grab bucket cover 2 motionlessly, the rotating disc 22 in rising turns.Rotating disc 22 bottoms with grab lobe transom 3 and be connected and fixed.Rotating disc 22 also is commercial existing procucts.
From Fig. 1, Fig. 3, Fig. 4 as can be seen, the utility model is some grab lobe 4 upper ends respectively with grab lobe transom 3 and be hinged, grab and be connected with its stretching, extension of control and closed hydraulic ram 6 and piston rod 7 on the lobe 4, hydraulic ram 6 is positioned at grabs lobe 4 inboards, it is connected with the fuel tank that uses machinery by high-pressure oil passage conduit 5, decompose in each hydraulic ram 6 by the oil circuit conduit, each piston rod 7 is produced shrink, stretch.As shown in Figure 3, grab lobe 4 and be provided with two hinge holes 41,42, grab the hinge hole 41 of lobe 4 one ends by playing the upper end and to grab lobe transom 3 hinged, hinge hole 42 be used for and piston rod 7 hinged.As shown in Figure 4, grab lobe transom 3 and also be provided with two hinge holes 31,32, hinge hole 31 is used for and to grab lobe 4 hinged, hinge hole 32 be used for and the outside of hydraulic ram 6 hinged.Like this, by operation modulated pressure oil cylinder 6 and piston rod 7, just can synchro control each grab the stretching, extension and the closure of lobe.Because grabbing lobe 4 is subjected to fluid control, it can be picked up exactly, put down object, can firmly grab object downwards after landing, and object can not omitted, and has improved efficient.
The utility model is rational in infrastructure, and dependable performance grasps great efforts, synchronism is good, high efficiency.Be applicable to be installed on hydraulic crane and all kinds of fluid pressure type loading-unload machine and use.
