Description
Technical field
The utility model relates to the pick arm configuration of a kind of tamping unit of railway maintenance machinery, particularly a kind of tamping unit.
Background technology
Pick arm on the tamping unit of railway maintenance machinery is the critical component of tamping unit, and it mainly acts on is fixedly tamping pickaxe and transmitting vibrations.During tamping operation, the pick arm will bear huge impact power and flexural stress, and the reliability direct relation of its quality the application life of tamping unit.The tamping car that uses on China's circuit mainly is to introduce from Austrian Plasser company; its pick arm configuration develops into the pick arm in the cylindrical tamping pickaxe of having of present use hole from the pick arm with conical tamping pickaxe hole; though the intensity of pick arm and installation way are improved and improve; but near the reinforcing rib place of these pick arms tamping pickaxe hole behind the long tamping operation crackle occurs through regular meeting.Influenced the application life of pick arm.
Summary of the invention
The purpose of this utility model is to provide a kind of force-bearing situation that can improve place, tamping pickaxe hole, improves the pick arm in application life.
In order to achieve the above object, the technical solution of the utility model is: a kind of pick arm, comprise the oil cylinder piston bar connecting portion that connects successively, casing connecting portion and tamping pickaxe connecting portion, oil cylinder piston bar connecting portion has oil cylinder piston bar hinge hole, the casing connecting portion has the casing hinge hole, the tamping pickaxe connecting portion has two tamping pickaxe holes, be connected with reinforcing rib between casing connecting portion and the tamping pickaxe connecting portion, on the described tamping pickaxe connecting portion and be positioned at the clamp that is equipped with a pair of parallel direction protuberance towards casing hinge hole axis on the outer wall in each tamping pickaxe hole, the clamping slot that extends along the hole wall generatrix direction in tamping pickaxe hole is arranged between each two right clamp, clamping slot connects with corresponding tamping pickaxe hole, have the bolt hole of mutual perforation on each two right clamp, the cell wall of clamping slot is parallel to the axis direction of casing hinge hole.
Also have the bolt hole of strutting on the clamp in described every pair of clamp, strut bolt hole and lead to clamping slot.
The central plane of described clamping slot is by the axis in two tamping pickaxe holes, and two cell walls of each clamping slot equate with the distance of central plane.
After adopting said structure, because on the tamping pickaxe connecting portion and be positioned at the clamp that is equipped with a pair of parallel direction protuberance towards casing hinge hole axis on the outer wall in each tamping pickaxe hole, the clamping slot that extends along the hole wall generatrix direction in tamping pickaxe hole is arranged between each two right clamp, clamping slot connects with corresponding tamping pickaxe hole, the bolt hole that has mutual perforation on each two right clamp, the cell wall of clamping slot is parallel to the axis direction of casing hinge hole, therefore, can effectively improve the force-bearing situation at place, tamping pickaxe hole, avoid the reinforcing rib place to crack, thereby improve the application life of pick arm.In addition, along the clamp structure that tamping pickaxe axially bored line direction is arranged, can also alleviate the machining deformation that place, tamping pickaxe hole produces.The utility model also is convenient to the dismounting of tamping pickaxe, is applicable to the multiple tamping unit that uses on the domestic existing line.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is the structural representation of the pick arm of prior art;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation of pick arm of the present utility model;
Fig. 4 is the B-B sectional view of Fig. 3;
Fig. 5 is the C-C sectional view of Fig. 3;
Fig. 6 is the D-D sectional view of Fig. 3.
The specific embodiment
As shown in Figure 1, 2, be the structural representation of the pick arm of domestic prior art tamping unit, the cell wall of two clamping slots 6 of pick arm 5 is all perpendicular to the axis direction of casing hinge hole 5-1.The fluting direction of clamping slot 6 makes reinforcing rib 7 positions bear bigger clamping force, and therefore, pick arm 5 regular meetings are prone to crackle in the position of reinforcing rib 7.
Shown in Fig. 3,4,5,6, be the structural representation of pick arm of the present utility model.A kind of pick arm, comprise the oil cylinder piston bar connecting portion 1 that connects successively, casing connecting portion 2 and tamping pickaxe connecting portion 3, oil cylinder piston bar connecting portion 1 has oil cylinder piston bar hinge hole 1-1, casing connecting portion 2 has casing hinge hole 2-1, tamping pickaxe connecting portion 3 has two tamping pickaxe hole 3-1, be connected with reinforcing rib 4 between casing connecting portion 2 and the tamping pickaxe connecting portion 3, on the described tamping pickaxe connecting portion 3 and be positioned at the clamp 3-2 that is equipped with a pair of parallel direction protuberance towards casing hinge hole 2-1 axis on the outer wall of each tamping pickaxe hole 3-1, the clamping slot 3-3 that extends along the hole wall generatrix direction of tamping pickaxe hole 3-1 is arranged between each two right clamp 3-2, clamping slot 3-3 and corresponding tamping pickaxe hole 3-1 connect, have the bolt hole 3-2-1 of mutual perforation on each two right clamp 3-2, the cell wall of clamping slot 3-3 is parallel to the axis direction of casing hinge hole 2-1.
Shown in Fig. 3,5,6, also have the bolt hole of strutting 3-2-2 on the clamp 3-2 among described every couple of clamp 3-2, strut bolt hole 3-2-2 and lead to clamping slot 3-3.
Shown in Fig. 4,5, in order further to alleviate the stressed of reinforcing rib position, the central plane F-F ' of described clamping slot 3-3 is by the axis of two tamping pickaxe hole 3-1, and two cell walls of each clamping slot 3-3 equate with the distance of central plane F-F '.
The structural change of clamp 3-2 in the utility model the direction of clamping slot 3-3 at 3-1 place, tamping pickaxe hole, the clamping that has improved the pick arm is stressed, has solved in the past the pick arm and has seen Fig. 1 at reinforcing rib 7() problem of crackle appears in position easily.Therefore, improve the life-span of pick arm, also be beneficial to the processing of tamping pickaxe hole 3-1 and the dismounting of tamping pickaxe simultaneously.
