The operation is carried out by a plurality of persons in a narrow space of the separator, the labor intensity is high, a plurality of unsafe factors exist, and the construction efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a shallow groove chain dismounting tool which is simple in structure, convenient and rapid to operate, time-saving, labor-saving, safe and reliable to operate.
The utility model is realized by the following technical scheme:
the utility model provides a shallow slot chain assembly and disassembly tools, its includes support body, hydraulic jack and thimble, the support body includes two side shields of bottom plate and fixed mounting on the bottom plate, hydraulic jack fixed mounting has seted up the round pin axle hole of stepping down on another side shield on a side shield, thimble fixed mounting is in hydraulic jack's ejector pin tip, fixed mounting has the layer board on the bottom plate, and fixed mounting has two limiting plates on the layer board.
Preferably, the hydraulic jack is connected with the hydraulic station through a hose.
Furthermore, two mounting holes which correspond to each other are respectively formed in the side baffles, reinforcing lead screws are mounted at the mounting holes, and the reinforcing lead screws and the corresponding side baffles are locked through locking nuts.
The utility model has the advantages of
The shallow slot chain disassembling tool provided by the utility model has the following advantages:
one, shorten the construction time
By adopting the original method for disassembling and assembling the chains, each joint takes 15 minutes. After the disassembling tool is adopted, the disassembling of one joint can be completed within 5 minutes, and the working time of each joint is shortened by 10 minutes.
And secondly, the number of constructors is reduced, the labor intensity is reduced, the operation is easy, and unsafe factors are reduced.
According to the original construction method, 3 workers are required to cooperate, one person places a cushion block between a chain and a groove body to support the chain, one person aligns a thimble with a chain pin shaft, and the other person uses a sledge hammer to knock the thimble. Three people gather in the narrow and small space of separation groove cell body, have a great deal of unsafe factors such as pound the hand, the extrusion, personnel drop, multiplexer utensil wounded.
The existing construction method only needs 2 staff for cooperation. Two persons cooperate to fix the tool on the chain, then one person stands on the shallow slot platform to operate the hydraulic pump station, and the other person stands in the slot body to observe the movement condition of the pin shaft and the thimble. The construction personnel are few, and reasonable emergency risk avoiding measures are easy to adopt.
Thirdly, the tool has small investment and simple structure
The tool is simple in structure, only 1 split type hydraulic jack needs to be purchased, the hydraulic pump station can be shared with other hydraulic tools, and the whole set of investment is about 800 Yuan.
Drawings
FIG. 1 is a schematic perspective view of the present invention;
in the figure, 1, a bottom plate, 2, a hydraulic jack, 3, a side baffle, 4, a locking nut, 5, a thimble, 6, a reinforcing screw rod, 7, a pin shaft abdicating hole, 8, a limiting plate, 9, a supporting plate and 10, a hydraulic station are arranged.
Detailed Description
The utility model provides a shallow slot chain assembly and disassembly tools, its includes support body, hydraulic jack 2 and thimble 5, the support body includes two side shields 3 of bottom plate 1 and fixed mounting on the bottom plate, hydraulic jack fixed mounting has seted up round pin axle hole 7 of stepping down on another side shield on a side shield, thimble fixed mounting is in hydraulic jack's ejector pin tip, fixed mounting has layer board 9 on the bottom plate, and the layer board is used for holding the go-between of chain, and fixed mounting has two limiting plates 8 on the layer board, and two limiting plates are used for supporting the round pin axle sleeve on the go-between, and the side shield that is equipped with round pin axle hole of stepping down supports the outside at the go-between.
Optimally, the hydraulic jack is connected with the hydraulic station 10 through a hose, so that the carrying, the dismounting and the mounting of tools are facilitated.
Further, two the mounting hole that corresponds each other has been seted up on the side shield respectively, and mounting hole department installs reinforcing screw 6, locks through lock nut 4 between reinforcing screw and the corresponding side shield, and reinforcing screw's setting can improve the reliability of operation, improves the joint strength between side shield and the bottom plate, prevents the two separation under the effect of jack to make things convenient for the dismouting, so that the location setting of instrument.
The utility model provides a shallow slot chain disassembling tool, which is operated according to the following steps when a chain needs to be replaced, a connecting ring needs to be replaced or the chain needs to be contracted:
firstly, the chain disassembling operation steps are as follows:
1. the thimble is fixed on the ejector rod of the hydraulic jack.
2. And fixing the hydraulic jack on the side baffle.
3. And the chain is placed in a space between the ejector rod and the side baffle plate, so that the ejector pin corresponds to the pin shaft of the chain, and the pin shaft sleeve of the chain is clamped between the two limiting plates for positioning.
