The log grapple is high in operation adaptability, stable and reliable in working, and uneasy to be damaged.
Description
Technical field
The utility model relates to a kind of loading machine device, especially relates to matching used novel loading machine log grapple on a kind of loading machine.
Background technology
At present loading machine is that to grasp transportation timber be a kind of general working method to supporting use log grapple, its log grapple mostly is the arcuation bracket that the two-phase interworking is closed, wherein go up fork and mostly be two pawl formula structures, two jaws are distributed in and arranged on left and right sides, middle no jockey is by being arranged on fork closure on the hydraulic oil cylinder driving between two brackets, opening the extracting and the clamping operation that realize timber.But increase along with the loading machine tonnage, distance on the log grapple between fork two jaws is in continuous increase, like this when grasping tiny timber operation, be subjected to the restriction of clamping ability, the spreading phenomenon takes place easily, the operation bad adaptability, operating efficiency is caused certain influence, and stressed greatly, fragile because of two jaws when grasping the big material of major diameter timber and density, cause job stability and poor reliability.
Summary of the invention
Technical problem to be solved in the utility model provided a kind of can operation adaptability height and the novel loading machine log grapple of stable and reliable operation.
For solving the problems of the technologies described above, the technical solution of the utility model is: novel loading machine log grapple, comprise lower fork, go up fork, be hinged between lower fork and the last fork to be connected to and drive the hydraulic jack of going up fork, described lower fork is provided with swing arm gripper shoe and link supports plate, the described fork of going up comprises and left and right sides gripper is provided with at least one connecting rod between the gripper of the described left and right sides that described left and right sides gripper two is grabbed and is provided with connecting plate between the leading section.
As a kind of improvement, described connecting rod comprises head rod and second connecting rod, two connecting rods.
As further improvement, described lower fork comprises left and right sides prong, is provided with first tube connector and second tube connector between the prong of the left and right sides, and first tube connector and second tube connector pass swing arm gripper shoe and link supports plate respectively.
As further improvement, described left and right sides gripper rearward end and hydraulic jack plunger end are hinged.
The novel loading machine log grapple of technique scheme, owing to be to have adopted to comprise lower fork, last fork, lower fork and on be hinged between the fork and be connected to the hydraulic jack of pitching in the driving, and be provided with swing arm gripper shoe and the link supports plate that is connected with loading machine at lower fork, and last fork comprises left and right sides gripper, be provided with at least one connecting rod between the gripper of the left and right sides, left and right sides gripper two is grabbed the mode that is provided with connecting plate between the leading section, make a fork left side, the monoblock type arcuate structure that forms between the right jaw, increased the envelope area, improved the adaptation of product, and last fork intensity has obtained reinforcement, improved the stability and the reliability of equipment when grasping the big material of major diameter timber and density, this device can grasp oil storage barrel simultaneously, circular material such as pipeline has further enlarged the scope of application of loading machine.Connecting rod adopts two connecting rods, and is simple and practical.Lower fork adopts between the prong of the left and right sides and is provided with two tube connectors, and two tube connectors pass swing arm gripper shoe and link supports plate respectively, has strengthened the fastness of lower fork, has also improved the reliability that is connected and works between whole log grapple and the loading machine.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Fig. 1 is the structural representation of the novel loading machine log grapple of the utility model;
Fig. 2 is the novel loading machine log grapple of a utility model vertical view;
Fig. 3 is the novel loading machine log grapple of a utility model side view.
The specific embodiment
As shown in Figure 1, novel loading machine log grapple, comprise the lower fork 2 that cooperatively interacts, on pitch 1, lower fork 2, on pitch 1 the mode that adopts the rear portion to be hinged by bearing pin more, and lower fork 2 and on be hinged between the fork 1 and be connected to the hydraulic jack 3 of fork 1 in the driving, like this work by operating hydraulically operated oil cylinder 3 drive go up fork 1 realize closed, open the function that grasps with clamping.On lower fork 2, be provided with swing arm gripper shoe 4 and link supports plate 5, log grapple by swing arm gripper shoe 4 be hinged with loading arm, link supports plate 5 and mode that the loading machine connecting rod is hinged realize and being connected and working under the driving of loading machine and control of loading machine.As shown in Figures 2 and 3, last fork 1 comprises left and right sides gripper 11,12, and in left and right sides gripper 11, be provided with at least one connecting rod between 12, in left and right sides gripper 11, grab for 12 liang and be provided with connecting plate 15 between the leading section, go up fork 1 like this by a left side, right jaw and connecting rod, the monoblock type arcuate structure that the connecting plate bar forms, increased the envelope area, improved the adaptation of product, and last fork intensity has obtained reinforcement, and for simplified structure, connecting rod can adopt two, as the head rod 13 and second connecting rod 14, according to the needs of operation, also can adopt three, the connecting rod of four or other number.And can adopt left and right sides gripper 11,12 rearward end and hydraulic jack 3 plunger end to be hinged in actual applications, be hinged mode as plunger end by bearing pin and hydraulic jack 3.Produce for convenience and increase the reliable steadiness that uses, can adopt the mode of welding to be connected between connecting rod, connecting plate and the left and right sides gripper.
As shown in Figures 2 and 3, lower fork 2 comprises left and right sides prong 21,22, between left and right sides prong 21,22, be provided with first tube connector 23 and second tube connector 24, and first tube connector 23 passes swing arm gripper shoe 4 respectively with second tube connector 24 fixedlys connected with left and right sides prong 21,22 with two ends, link supports plate 5 back, according to the needs of operation, also can adopt the tube connector of three, four or other number.So not only strengthen the fastness of lower fork 2, also improved the reliability that is connected and works between whole log grapple and the loading machine.
In use, the control by equipment on the loading machine with drive work such as the elevate a turnable ladder of handling lower fork 2, upset, and by 3 work of control hydraulic jack drive go up fork 1 realize closed, open to grasp and cooperate the realization holding function with lower fork 2.
This novel loading machine log grapple can exchange with the scraper bowl of loading machine and use, only the control that need increase hydraulic jack gets final product, the vehicle body of loading machine, vehicle frame, swing arm and equipment then need not change, very convenient, realized a tractor serves several purposes, greatly reduce customer using cost, improve service efficiency.
