The utility model is characterized in that the crawler guard board also comprises a left connecting plate, a right connecting plate, a front bottom plate and a rear bottom plate; the connecting plates are arranged above the body and are fixedly connected with the vertical plates and the side plates at the corresponding sides and ends, so as to form a cavity used for containing supporting wheels; the front end and the rear end near the cavity on each connecting plate are respectively provided with screw holes, and the connecting plates are connected with a vehicle frame by the screw holes; and the front and the rear bottom plates are arranged along the extending directions of the bottom parts of the front and the rear vertical plates at the corresponding ends and are welded and fixed with the vertical plates at the corresponding ends. In the utility model, the bottom parts of the vertical plates are additionally provided with the bottom plates for enhancing the deformation-resistance force, and the front and the rear vertical plates and the left and the right side plates are connected by the left and the right connecting plates, so as to form the cavity used for containing the supporting wheels, so that the connecting plates are connected with the vehicle frame, thereby reducing the mounting place of the body, realizing the nearly complete protection for the mounting of the supporting wheels and prolonging the service life of the traveling gear.
Description
Technical field
The utility model relates to a kind of engineering machinery walking device, is specifically related to a kind of backplate that is installed on the running gear crawler belt outside, is used for the caterpillar wheel of guard rows walking apparatus.
Background technology
Construction machinery and equipment relies on the running gear of bottom of frame to move usually, running gear is divided into two kinds of crawler type and rubber-tyreds, it is big that cterpillar drive has a propulsive effort, it is little to connect specific pressure, off-road capability and good stability, hill climbing ability is big, and turn radius is little, characteristics such as alerting ability is good are used comparatively general on hydraulic excavator.Cterpillar drive is by " four-wheel one band " (being drive wheel, track adjusting wheel, caterpillar wheel, support roller and crawler belt), tightening device and buffering spring, traveling gear, compositions such as walker.During the excavating machine operation, drive wheel is in the pilled-in selvedge of crawler belt---and drive section and ground connection section (supporting section) and produce a pulling force, attempt is pulled out crawler belt under caterpillar wheel, owing between crawler belt under the caterpillar wheel and ground enough adhesive ability is arranged, stop pulling out of crawler belt, force drive wheel scrolling crawler belt, track adjusting wheel is routed to crawler belt on the ground again, thereby makes excavating machine borrow caterpillar wheel along crawler belt track ahead running.
The above large excavator of 40T is mainly served on the field of opencast mining, is used for unsoil, digging ore and matchmaker, its working environment and abominable, and caterpillar wheel will stand the impact of very big stone and matchmaker's piece this moment, and suffered load is very big.Be the protection caterpillar wheel, adopt installation crawler belt backplate to realize usually, prolong its service life as much as possible, save use cost; The crawler belt backplate can also prevent that crawler belt from laterally coming off simultaneously.
Present employed crawler belt backplate as shown in Figure 1, comprise that the side plate that forward and backward riser and both sides connect to ground constitutes, the side plate bottom is fixing with the riser welding, the top is to the crooked curved flange shape in both sides, form the mounting plane that is spirally connected with vehicle frame, by the screw of offering on the mounting plane and vehicle frame through bolt.In the process of practice of construction, riser is often impacted by outer carrying such as stone or coal cinder, causes damage, insufficient strength.This structure installation dimension is bigger in addition, and the installation position between adjacent caterpillar wheel is limited, and outwards the mounting plane that is provided with has occupied the space between caterpillar wheel, so the mode that only can take usually to install is at interval protected caterpillar wheel, can't protect entirely caterpillar wheel.
Summary of the invention
The utility model purpose provides a kind of running gear crawler belt backplate, by the improvement to structure, can improve the caterpillar wheel protection domain, increases impact resistance, prolongs the service life of caterpillar wheel, reduces the working service cost.
For achieving the above object, the technical solution adopted in the utility model is: comprise the body that forward and backward riser and left and right side plate constitute, comprise left and right two connecting panels and forward and backward two base plates, described connecting panel is positioned at the top of described body, and captive joint with riser, the side plate of respective side, corresponding end, surround the cavity that holds caterpillar wheel, on each described connecting panel, the forward and backward two ends of nearly described cavity side offer a screw respectively, connect to ground through this screw; Described forward and backward base plate is arranged along the described forward and backward riser bottom bearing of trend of corresponding end, and is fixing with the riser welding of corresponding end.
In the technique scheme, described forward and backward riser and left and right side plate are individually fixed on two connecting panels that are arranged at its top, surround the cavity that can hold for caterpillar wheel, and be provided with base plate in the bottom of forward and backward riser, this base plate can adopt and add plate iron and make, and is intensity and the torsion stiffness that improves riser; When mounted; will be by preceding; back vertical plate; a left side; a right side board and a left side; the panel reality that right connecting panel surrounds is placed on the caterpillar wheel from bottom to top; by the screw of offering on the connecting panel; be bolted on the vehicle frame; described screw is positioned on the connecting panel of nearly cavity side; thereby the occupied installing space of body is less; space between adjacent caterpillar wheel can hold the shared installing space of adjacent body; make the caterpillar wheel of parallel arranged remove head; beyond two on the tail, all the other all sheathed panel realities are accomplished near the backplate that protects entirely; protect corresponding caterpillar wheel thus, can prevent that the chain rail from laterally holding in the palm the effect of chain simultaneously.
In the technique scheme, between the described forward and backward riser, corresponding and arranged on left and right sides is respectively equipped with a stud, and this stud and respective side side plate are arranged in parallel, and captives joint with described connecting panel in the top of described stud, captives joint with the riser of corresponding end in two ends.Both sides are provided with the intensity that stud can be strengthened whole body frame structure, strengthen the non-deformability of side.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model connects forward and backward riser and left and right side plate by two connecting panels, surrounds the cavity that holds caterpillar wheel, and the bottom that is positioned at forward and backward riser is provided with base plate, reinforces riser with this, improves single-piece torsion stiffness and intensity;
2; because the screw on the connecting panel is arranged to be bordering on and holds the caterpillar wheel cavity side; thereby with the texture ratio of in the past on outside flange mounting plane, offering mounting hole; connecting panel takes up room and dwindles; between adjacent caterpillar wheel in the limited space; can hold adjacent body connecting panel; thereby realize except that head; beyond two caterpillar wheels of tail; all can a sheathed panel reality on all the other each caterpillar wheels arranged side by side; accomplish near the backplate protection of protecting entirely; improve protection thus to whole running gear caterpillar wheel; simultaneously can prevent that the chain rail from laterally holding in the palm chain, improve the safety in utilization of running gear.
