Abstract
The utility model relates to a take mechanically fastening round pin of tight device that rises to demolish device, including the jack of symmetry setting the top of jack be equipped with the roof the roof on set up the through -hole the through -hole in be equipped with the pull rod the pull rod top be equipped with the screw thread the screw thread on be equipped with fixation nut the bottom of pull rod be equipped with the tight device that rises. After having adopted above -mentioned structure, adopted above -mentioned structure after, personnel's rate of utilization has been practiced thrift to the efficiency of construction of improvement, has reduced the loss of personnel's physical power, instruments such as out of use sledgehammer, long hammer drill, personnel remote operation goes wrong can not threaten operation personnel's safety, all part repeatedly usable are not that once only the investment is used, this device can be gone into the well and used in work, and walking wheel, guide shoe etc. Can change at the scene from now on.
Description
Technical field
This utility model relates to a kind of auxiliary device in mining technique industry, especially relates to a kind of band swelling device
It is mechanically fixed pin and removes device.
Background technology
Currently used coal machine needs to change road wheel, guide boots after a long time use, and road wheel, guiding boots are fixed
Pin cannot pull out in down-hole, can only be by whole running part gug when needs change road wheel, guiding boots, then on ground more
Change, extremely inconvenience.Even if running part has arrived ground and has faced taking-up steady pin the most difficultly, because it coordinates for closely cooperating in addition
Mix its tightness with coal, spoil, water in down-hole very big, the most only corrode with diesel oil, after join with sledgehammer, copper rod, jackscrew etc.
Conjunction goes out, the risk that security presence is certain when the instrument such as sledgehammer, copper rod of use.After use hydraulic nut instead, but hydraulic nut
Stroke is less the most more.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of convenient dismounting steady pin and ensures safe band
The pin that is mechanically fixed of swelling device removes device.
The technical scheme in the invention for solving the technical problem is: a kind of band swelling device be mechanically fixed pin
Remove device, including symmetrically arranged jack, be arranged over top board at described jack, described top board is offered
Through hole, is provided with pull bar in described through hole, is provided with screw thread at described pull bar top, is provided with fixing spiral shell on described screw thread
Mother, is provided with swelling device in the bottom of described pull bar.
The most concrete, described swelling device includes a tensioner part, is provided with endoporus, in institute in described tensioner part
The endoporus stated is provided with screw thread, is provided with screw thread and coordinates with inner hole thread bottom described pull bar, at described tensioner part head
The hole being provided with inverted cone connects with endoporus, and described inverted cone offers a point groove, and described point groove is by tensioner part head decile
It is three parts.
The most concrete, described jack is hydraulic jack and is connected with hydraulic pump.
The most concrete, described top board uses the steel plate of two 30mm thickness to be formed by stacking.
The most concrete, described hydraulic jack connects and has pressurized cylinder.
The beneficial effects of the utility model are: after have employed said structure, after have employed said structure, and executing of raising
Work efficiency rate, has saved librarian use rate, reduces personnel's physical power loss；Not in use by the instrument such as sledgehammer, long hammer drill, personnel are long-range
Operation goes wrong the safety of not entail dangers to operating personnel；All parts are reusable is not that one-time investment uses；This dress
Put and can enter well and use in work, from now on road wheel, guide boots etc. and can change at the scene.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, jack；2, top board；3, pull bar；4, fixing nut；5, tensioner part；6, endoporus；7, inverted cone；8, divide
Groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is explained in detail.
The pin that is mechanically fixed of a kind of band swelling device removes device, including symmetrically arranged jack 1,
Described jack 1 be arranged over top board 2, through hole offered by described top board 2, in described through hole, is provided with pull bar 3,
It is provided with screw thread at described pull bar 3 top, described screw thread is provided with fixing nut 4, be provided with in the bottom of described pull bar 3
Swelling device；Described swelling device includes a tensioner part 5, is provided with endoporus 6 in described tensioner part 5, at described endoporus 6
It is provided with screw thread, is provided with screw thread and endoporus 6 threaded engagement bottom described pull bar 3, is provided with down at described tensioner part 5 head
The hole of taper 7 connects with endoporus 6, and described inverted cone 7 offers point groove 8, and described point groove 8 is by tensioner part 5 head decile
It is three parts；Described jack 1 is hydraulic jack and is connected with hydraulic pump；Described top board 2 uses two 30mm thickness
The steel plate of degree is formed by stacking；Connect in described hydraulic jack and have pressurized cylinder.
The hydraulic pump utilizing the 25MPa of every day use uses.First select 2 diameter 100mm stroke 100mm's
Jack 1 makees liftout attachment, afterwards with the steel plate of two pieces of thickness 30mm as top board 2, then makees with the high-strength bolt of length 450mm
For pull bar 3, installing swelling device for one and is connected with steady pin, pull bar 3 rotates so that tensioner part 5 head becomes big and fixes and locks
Contiguity is touched, and jack 1 is connected with hydraulic pump, and personnel can remotely operate.As may utilize supercharging when steady pin cannot be pulled out by pressure
Cylinder carries out secondary booster, and personnel can remotely operate (utilizing operation valve) equally.
It is emphasized that: be the most only preferred embodiment of the present utility model, not this utility model appointed
What pro forma restriction, every according to technical spirit of the present utility model, above example is made any simple modification, etc.
With change and modification, all still fall within the range of technical solutions of the utility model.
