Technical field
The present invention relates to a kind of interior movable machine core trolley of casing of flame-proof mine electric equipment.
Background technology
Fixed or the movable movement of the normal employing of the installation of electric device in downhole explosion-proof box body for coal mine, the movable installation of many employings when electric device is more, heavier, restriction due to the explosion-proof casing volume, the trolley type flexible movement can only be limited in certain space, this brings difficulty just for the installation of components and parts and the assembling and setting of movement and casing, usually occur in erecting yard and be difficult to debugging and put in place, simultaneously, in transportation because movement dislocation causes the components and parts phenomenons such as damage that bump.
Summary of the invention
The invention provides the machine core trolley in a kind of downhole explosion-proof box body for coal mine, solved electric device in downhole explosion-proof box body for coal mine movement dislocation and the problem that causes components and parts to bump and damage in transportation.
The present invention overcomes the above problems by following scheme:
machine core trolley in a kind of downhole explosion-proof box body for coal mine, comprise flameproof cabinet and machine core trolley, be fixedly installed the casing backing plate at the bottom of case in flameproof cabinet, two guide rails of set of rails are fixedly installed on the casing backing plate by set bolt, be fixedly installed the centering plate on the front end of the set of rails direction vertical with guide rail, be provided with a pair of to mesopore on the centering plate, front end at the car body of machine core trolley is fixedly installed a pair of to axis, this is to coordinating mesopore is movable of arranging on axis and centering plate, bottom at the car body of machine core trolley is provided with the promotion bolt, be fixedly installed backing plate on the direction vertical with guide rail of the rear end of set of rails, be fixedly installed advance seat on backing plate, be provided with the mating holes that promotes bolt on advance seat.
Described promotion bolt is arranged between the bearing pedestal and bearing cap that the machine core trolley bottom is fixedly installed.
The invention provides a kind of fixture for the machine core trolley under coal mine and integrated guide rail, this structure can solve the problem of the assembling and setting difficulty of the interior movement of flameproof cabinet and casing, guarantee movement and casing fixation, have advantage simple in structure, safe and reliable.

Specific embodiment
machine core trolley in a kind of downhole explosion-proof box body for coal mine, comprise flameproof cabinet 4 and machine core trolley 3, be fixedly installed casing backing plate 1 at the bottom of case in flameproof cabinet 4, two guide rails 8 of set of rails 2 are fixedly installed on casing backing plate 1 by set bolt 5, be fixedly installed centering plate 6 on the front end of set of rails 2 direction vertical with guide rail 8, be provided with a pair of to mesopore 11 on centering plate 6, front end at the car body 17 of machine core trolley 3 is fixedly installed a pair of to axis 12, this is to coordinating mesopore 11 is movable of arranging on axis 12 and centering plate 6, be provided with and promote bolt 16 in the bottom of the car body 17 of machine core trolley 3, be fixedly installed backing plate 7 on the direction vertical with guide rail 8 of the rear end of set of rails 2, be fixedly installed advance seat 9 on backing plate 7, be provided with the mating holes that promotes bolt 16 on advance seat 9.
Described promotion bolt 16 is arranged between the bearing pedestal 13 and bearing cap 14 that the machine core trolley bottom is fixedly installed.
Casing backing plate 1 is to be fixedly welded on flameproof cabinet 4, and wherein set of rails 2 is to be arranged on casing backing plate 1 with set bolt 5 is fastening.Described set of rails 2, centering plate 6 and backing plate 7 are the front and rears that are fixedly welded on guide rail 8, advance seat 9 is to be fixedly mounted on backing plate 7 with bolt 10.Have two on centering plate 6 to mesopore 11, be with machine core trolley on axis 12 is used in conjunction with.Car body 17 front portions are fixedly installed two to axis 12, and bearing pedestal 13 and bearing cap 14 are fixedly mounted on the rear portion of car body 17 by hold-down screw 15, promote bolt 16 and are contained between bearing pedestal 13 and bearing cap 14, with the advance seat 9 on set of rails, form propulsive mechanism.Set of rails 2 is used in conjunction with machine core trolley 3, rotate and promote bolt 16, make in its screw that screws in advance seat 9, drive the machine core trolley motion, simultaneously on machine core trolley to axis 12 insert centering plate 6 on set of rails in mesopore 11, until axis is coordinated and puts in place with the centering plate.
Because the present invention adopts the fixing designing technique of machine core trolley and integrated guide rail; make movement just can carry out trial assembly with set of rails before entering casing; adjustment and installation is convenient; after integrated guide rail is fixedly installed on casing; machine core trolley pushes casing; and, by promoting to be bolted to position, can guarantee movement and casing fixation, the assembling and setting difficult problem that has solved movement and casing reaches that in transportation movement is dislocated and the problem that causes components and parts to bump.
First with fastening being arranged on casing backing plate 1 of 6 set bolts 5 of set of rails 2 use, then machine core trolley 3 is placed on the guide rail front end, precession promotes bolt 16 makes machine core trolley enter casing, promoting bolt 16 screws in the process of advance seat 9, on machine core trolley to axis 12 insert with set of rails on centering plate 7 in, when promotion spiral shell 16 screw-ins put in place, axis is also pegged graft and put in place, fixedly reach the purpose of movement and the whole fixation of casing by the front and back of machine core trolley.
