Description
Technical field
The utility model relates to a kind of special dismantling device of dump truck balancer axle connecting pin.
Background technology
Dump truck is the vehicle of the tipping short distance convey materials of a kind of special hopper, vehicle body is provided with " bucket " shape container, can overturn to facilitate unloading, be applicable to building, water conservancy, build the road, short-distance transport that the various loose unpacked materials such as concrete, sandstone, the earthwork, coal, ore are made in mine etc.Along with vehicle uses for a long time, mechanical aging is serious, upkeep operation is implemented after frequent needs dismounting drives bridge and balancer axle connecting pin, but due to vehicle width and attach structure compact, balancer axle connecting pin directly cannot adopt the dismounting that hits with a hammer, and the direct shakedown of oxygen, acetylene air gun can only be adopted to remove, connecting pin cannot reuse, and very easily damage the pin-and-hole of balancer body, such that job scheduling is slow, overhaul efficiency is low, there is certain potential safety hazard simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of special dismantling device of dump truck balancer axle connecting pin, this instrument is utilized conveniently to realize the dismounting of connecting pin, avoid the damage of balancer body pin-and-hole and the potential safety hazard of upkeep operation, improve the efficiency of dismounting operation.
For solving the problems of the technologies described above, the special dismantling device of the utility model dump truck balancer axle connecting pin comprises front apron, backboard and at least three double threaded screws, described front apron and backboard center have through hole, described front apron and backboard peripheral intervals are provided with at least three screws, described front apron and backboard interval are arranged, described at least three double threaded screw two ends are twisted respectively in the screw of described front apron and backboard.
Further, this instrument also comprises some locking nuts, and described some locking nuts are twisted respectively in described at least three double threaded screws and are positioned at the both sides of described front apron and the both sides of described backboard.
Further, this instrument also comprises stiffener, and described stiffener is located between adjacent double threaded screw.
Because the special dismantling device of the utility model dump truck balancer axle connecting pin have employed technique scheme, namely this instrument comprises front apron, backboard and at least three double threaded screws, described front apron and backboard center have through hole, described front apron and backboard peripheral intervals are provided with at least three screws, described front apron and backboard interval are arranged, described at least three double threaded screw two ends are twisted respectively in the screw of described front apron and backboard.This instrument conveniently realizes the dismounting of connecting pin, avoids the damage of balancer body pin-and-hole and the potential safety hazard of upkeep operation, improves the efficiency of dismounting operation.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the special dismantling device schematic diagram of the utility model dump truck balancer axle connecting pin.
Detailed description of the invention
As shown in Figure 1, the special dismantling device of the utility model dump truck balancer axle connecting pin comprises front apron 1, backboard 2 and at least three double threaded screws 3, described front apron 1 and backboard 2 center have through hole 11,21, described front apron 1 and backboard 2 peripheral intervals are provided with at least three screws, described front apron 1 and backboard 2 interval are arranged, described at least three double threaded screws 3 two ends are twisted respectively in the screw of described front apron 1 and backboard 2.
Further, this instrument also comprises some locking nuts 4, and described some locking nuts 4 are twisted respectively in described at least three double threaded screws 3 and are positioned at the both sides of described front apron 1 and the both sides of described backboard 2.
Further, this instrument also comprises stiffener 5, and described stiffener 5 is located between adjacent double threaded screw.Stiffener is for improving the rigidity of whole instrument.
When the connecting pin dismounting operation of dump truck balancer axle, front apron and backboard are arranged at connecting pin two ends, front apron is against balancer body, a determining deviation is there is between backboard and connecting pin, double threaded screw is adopted front apron and backboard to be connected, and make the central through hole of front apron and backboard and connecting pin be positioned at same axis, the depth of parallelism of front apron and backboard is adjusted by double threaded screw, some locking nuts can be adopted after adjustment to lock the position of front apron and backboard, then between backboard and connecting pin, hydraulic jack is placed, jack stand is against backboard, piston rod is connected pin, start hydraulic jack, piston rod pushing tow connecting pin, connecting pin pushing-out flat weighing apparatus body pin-and-hole being stretched out at central through hole by front apron under the effect of axial force, thus realize the field-strip of connecting pin.When connecting pin is installed, by the piston rod of hydraulic jack, connecting pin is headed into balancer body pin-and-hole equally.
This tool construction is simple, easy to operate, wherein front apron and backboard can make according to the actual outer dimensions of vehicle, be the main body frame of this instrument, and be integrally formed by double threaded screw, front apron and backboard bear the thrust of hydraulic jack, until connecting pin is pushed out or heads into, the central through hole one of front apron and backboard is the passage that connecting pin stretches out, and it two is the locating hole of hydraulic jack, to ensure that hydraulic jack and connecting pin are on same axis line; Front apron and backboard are linked to be overall structure and jointly bear the thrust of hydraulic jack by double threaded screw, it can according to the distance between the practical structures adjustment front apron of vehicle and backboard, to meet the use of this instrument at different size vehicle, simultaneously for adjusting the depth of parallelism between front apron and backboard, guarantee that hydraulic jack and connecting pin are positioned at same axis, realize the dismounting of connecting pin.
