Abstract
The utility model discloses a safeguard structure of a travel motor, which includes a support seat surrounded by a vertical plate, a horizontal plate and an arc plate, wherein a fixing seat is arranged on the inner side of the arc plate, and a motor cover plate is arranged on a fixing seat. The safeguard structure is characterized in that a turned-over edge matched with the inner surface of the vertical plate is arranged on the motor cover plate and close to the vertical plate side, and screw holes matched with each other are formed on the turned-over edge and the vertical plate respectively and fixedly connected through a bolt. The motor cover plate is fixed by screwing an extended plate and the vertical plate together, so that the exposing condition of a fixing bolt is avoided, the damage rate is reduced, the service life is prolonged, an assembling bolt is not influenced by the welding deformation, and the assembly and disassembly are more convenient.
Description
Technical field
The utility model relates to a kind of engineering machinery cterpillar drive, is specifically related to a kind of safeguard structure of running motor.
Background technology
Engineering machinery 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 driving force, it is little to connect specific pressure, cross-country ability and good stability, climbing capacity is big, and turning radius is little, characteristics such as flexibility is good are used comparatively general on hydraulic crawler excavator.Crawler type walking mechanism, generally by fluid motor-driven, motor is installed in the supporting base of track frame, and supporting base one end adopts the motor cover plate that the fluid pressure line of motor is partly protected.
Existing motor safeguard structure as shown in Figure 1, 2, supporting base is a welded construction, constitute by riser 21, transverse slat 22 and 23 welding of peripheral arc, motor 24 is arranged in the arc 23, arc 23 left and right inboards are provided with 4 holders 25 that are threaded through hole, motor cover plate 26 is held on the holder 25, and fixedly connected by bolt 27, and motor 24 is sealed up for safekeeping within cover plate.Yet the problem that this structure exists is:
1. because whole supporting base is a welded construction, the stress deformation after the welding easily causes the motor cover plate situation that bolt hole can't be aimed to occur when installing, and brings very burden to assembling;
2. motor cover plate set bolt is exposed to the cover plate outside, owing to get off frequent operation in some adverse circumstances, bolt is easy to damage;
3. cover plate is difficult for during repair demolition taking out in the inside of arc.
Summary of the invention
The utility model purpose provides a kind of safeguard structure of running motor, by improving structure, makes Assembly And Disassembly become more simple and convenient, is convenient to the maintenance to motor and fluid pressure line, has simplified mounting structure simultaneously, has improved application life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of safeguard structure of running motor, comprise the supporting base that surrounds by riser, transverse slat and arc, the arc inboard is provided with holder, the motor cover plate is arranged on the described holder, the nearly described riser side of described motor cover plate is provided with the flange that cooperates with the riser inner surface, and described flange is provided with the screw that matches with described riser, and connects through bolt.
In the technique scheme, motor is installed in the supporting base, and the motor cover plate is placed on the motor top, provides supporting by the holder that is arranged on the arc for cover plate, after the motor cover plate covers, corresponding by the screw that is arranged on the cover plate flange with screw on the riser, fixing after in riser lateral-supporting seat, passing two screws with bolt, replace on the cover board offering the fixing mode of bolt hole with this in the past, bolt is concealed behind riser, make it to be protected, avoid exposing, reduce and damage probability; Simultaneously, bolt is not influenced by welding deformation, assembles more convenient.
In the technique scheme, described motor cover plate top surface middle part is provided with 2 thin plates.Two thin plates of motor cover plate outside weldings, during assembly and disassembly, thin plate can be used as handgrip, takes out the motor cover plate easily.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because the flange that the utility model cooperates with riser surface in the one side setting of motor cover plate, pass riser by bolt and fixedly connected the motor cover plate with the screw on the flange, bolt is hidden in the rear of riser, avoids bolt to expose on the one hand, reduce the damage possibility, increase the service life; On the other hand, the correspondence of screw is not influenced by welding deformation during assembling, and it is more easy to assemble;
2, motor cover plate top surface middle part is provided with 2 thin plates, when assembling and dismounting motor cover plate, just operating personnel's gripping, operate more convenient, hommization.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: shown in Fig. 3～6, a kind of safeguard structure of running motor comprises the supporting base that is surrounded by riser 1, transverse slat 2 and arc 3, and motor 4 is arranged in the supporting base, and draw in the aperture 6 of fluid pressure line 5 on riser 1; Arc 3 inboards are welded with holder 7, motor cover plate 8 is held on the described holder 7, for motor cover plate 8 provides supporting, the flange 9 that extend under described motor cover plate 8 nearly described riser 1 side direction, cooperates with riser 1 inner surface, described flange 9 is provided with the screw 12 that matches with described riser 1, and fixedly connected through hidden bolt 10 behind riser 1, be damaged avoiding; Motor cover plate 8 end faces middle part is welded with 2 thin plates 11, when being used for assembling or dismounting motor cover plate 8, grips motor cover plate 8.
