Description

One kind is mostly used hydraulic to unload chain device
Technical field
The utility model relates to a kind of extracting tools of roller.
Background technique
The hydraulic chain device that unloads is a kind of roller chain extracting tool, using hydraulic energy as power, ejects chain hinge pin, convenient Quick disassembly chain.The existing hydraulic chain fixed form for unloading chain device is flange Method for Installation, is fixed using twin-screw;It is dismantling When chain hinge pin, it is necessary to while the central point of two pin shafts is found, allowable error is small, inconvenient for operation;And it is existing hydraulic It is bad to unload chain device versatility, the different chain of model is often dismantled using the special corresponding hydraulic chain device that unloads.
Utility model content
In order to solve above-mentioned drawback, technical problem to be solved by the utility model is to provide a kind of easy to operate, general Good hydraulic of property unloads chain device.In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is that one kind is mostly used hydraulic Unload chain device, including Manual hydraulic jack, which is characterized in that further include U-shaped locating slot, the opposite two sidewalls of U-shaped locating slot It is equipped with coaxial mounting hole and crosses pin hole, the bottom surface of U-shaped locating slot opens up axial trapezoidal mounting groove;The hydraulic jack Cylinder body is adjusted by the thread mechanism and is fixed in the mounting hole of U-shaped locating slot;The mandril top of the hydraulic jack is fixedly mounted with peace Seat is filled, removably device ejector pin in mounting base;The trapezoidal bottom of corresponding nesting chain backing plate in the trapezoidal mounting groove of axial direction , bearing arc groove is equipped at the top of chain backing plate, bearing arc groove corresponds to mounting hole and crosses pin hole setting.
By adopting the above technical scheme, cylinder surface installation is screwed, and can be positioned, and realize position adjustment function; Ejector pin be it is detachable, corresponding ejector pin is assembled according to different chain;It, only need to be by a rolling of chain when dismantling chain hinge pin Son is placed in the bearing arc groove of chain backing plate, can quickly and easily complete to position, and can be according to the chain of different model Assemble the chain backing plate with corresponding bearing arc groove.
From the foregoing, it will be observed that the beneficial effects of the utility model are, the tool is easy to use, easy for assemble or unload reliable.Energy It is enough quickly and safely to dismantle chain hinge pin, extend the service life of chain;Versatility is good, and a tool can satisfy Multiple Type The dismantlement work of roller chain.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have Body embodiment is further described in detail the utility model.
Detailed description of the invention
Fig. 1 is the overall structure diagram of stripping attachment;
Fig. 2 is chain backing plate schematic view of the front view;
Fig. 3 is chain backing plate right side structural representation.
Specific embodiment
Referring to attached drawing, reflect a kind of specific structure of the utility model, it is described to be mostly used the hydraulic chain device that unloads including passing through pressurization Handle 6 carries out the hydraulic jack of hand work, further includes U-shaped locating slot 1.The opposite two sidewalls of U-shaped locating slot 1 are equipped with Coaxial mounting hole 9 is with pin hole 7 excessively, the trapezoidal mounting groove 8 that the bottom surface of U-shaped locating slot 1 is axially opened up along groove body.
The side surface of the cylinder body 4 of the hydraulic jack is equipped with screw thread, corresponding in mounting hole 9 to be threadedly engaged, by cylinder Body 4 is fixed in the mounting hole 9 of U-shaped locating slot;And position adjustment function is realized by being threadedly engaged mechanism.
The top of the mandril of the hydraulic jack is fixedly mounted with mounting base 3, passes through detachable locking nut in mounting base 3 Device ejector pin 2.The ejector pin 2 that plurality of specifications is prepared according to the pin shaft size of different chains, can fill according to the chain of different model With corresponding ejector pin 2, so that ejector pin 2 is matched with the pin shaft 12 of chain.
The trapezoidal pedestal 501 of nesting chain backing plate 5 is corresponded in trapezoidal mounting groove 8, and bearing arc is equipped at the top of chain backing plate 5 Slot 502, the corresponding mounting hole of bearing arc groove 502 are arranged with pin hole is crossed, only need to be by one of chain when dismantling the pin shaft 12 of chain 11 side of roller is placed in bearing arc groove 502, can quickly and easily complete to position, so that one end of pin shaft 11 is directed at ejector pin 2, the other end was directed at pin hole 7, depressed pressurized handgrip 6, and ejector pin 2 exits pin shaft 11 from the carrier bar 10 of chain, passed through described Pin hole 7 is crossed, dismounting hinge pin is quickly and safely completed.
11 diameter of roller of the chain of different model is different, can configure various types of chain backing plates 5, supports arc The radian of slot 502 matches setting with the roller of various specifications.When dismantling the chain of different model, taken out from trapezoidal mounting groove 8 Chain backing plate 5 out, another chain backing plate 5 with corresponding bearing arc groove 502 of replacement assembly.
Above-mentioned implementation is merely to clearly illustrate the technical solution of the utility model, and should not be understood as to this Utility model makes any restrictions.The utility model has well known a variety of substitutions or deformation in the art, is not taking off Under the premise of from the utility model in essence meaning, the protection scope of the utility model is each fallen within.
