Abstract

A kind of pin pulling out device, comprise slide block, force rod, fixed block and spring, slide block is provided with through hole, and force rod is through through hole, and slide block can slide on force rod; Force rod one end is provided with block, and the other end is provided with bolt of pulling pin, and is provided with fixed block, is provided with spring between fixed block and slide block near the one end being provided with bolt of pulling pin.One end that force rod is provided with block is provided with external screw thread, and block is fixed on force rod by being connected with external screw thread by locking nut.The contact surface of block and slide block is respectively equipped with the first cushion and the second cushion.By adopting above structure, by the spring arranged, in the process that slide block moves down, spring applies an elastic force upwards to slide block, makes slide block larger to block power, promotes efficiency of pulling pin; The cushion arranged then can avoid the noise caused in knockout process, if hand is placed between slide block and block by staff because of carelessness simultaneously, cushion opponent can also play certain protective role, reduces to be knocked the injury caused.

Description

A kind of pin pulling out device
Technical field
The utility model relates to a kind of instrument, particularly a kind of pin pulling out device.
Background technology
When plant equipment dismounting, maintenance, often needing to choose connects the pin of similar pin, taper pin between each parts, and different with the active force knocking in pin, pin of choosing often needs the power contrary with knocking in pin effect.Pin of choosing at present mainly takes method to have the instruments such as direct hammer oppositely to knock pin, or utilizes pin removal to choose.Utilize hammer to knock, its process of pulling pin is very difficult, wastes time and energy; And pin removal is also comparatively required great effort, and a large amount of noise can be produced, and slightly not note to damage the hand of staff.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pin pulling out device, effectively can promote efficiency of pulling pin, and can solve the noise problem of existing pin removal simultaneously, avoids the operate miss in the process of pulling pin to cause injury to staff simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of pin pulling out device, and comprise slide block, force rod, fixed block and spring, slide block is provided with through hole, and force rod is through through hole, and slide block can slide on force rod;
Force rod one end is provided with block, and the other end is provided with bolt of pulling pin, and is provided with fixed block, is provided with spring between fixed block and slide block near the one end being provided with bolt of pulling pin.
In preferred scheme, one end that described force rod is provided with block is provided with external screw thread, and block is fixed on force rod by being connected with external screw thread by locking nut.
In preferred scheme, described block and the contact surface of slide block are respectively equipped with the first cushion and the second cushion.
In preferred scheme, described force rod passes through sleeve connection with bolt of pulling pin.
In preferred scheme, described sleeve is provided with internal thread, and one end of force rod and sleeve connection is provided with one section of external screw thread, and bolt of pulling pin is provided with external screw thread, and force rod and sleeve, sleeve and pulling pin between bolt is threaded connection.
In preferred scheme, described slide block is also provided with handle.
A kind of pin pulling out device that the utility model provides, by adopting above structure, utilizing slide block upwards to clash into block and applying a power upwards to force rod, drives the pin needing to pull out, thus carries out work of pulling pin.By the spring arranged, in the process that slide block moves down, spring applies an elastic force upwards to slide block, makes slide block larger to block power, promotes efficiency of pulling pin; The cushion arranged then can avoid the noise caused in knockout process, if hand is placed between slide block and block by staff because of carelessness simultaneously, cushion opponent can also play certain protective role, reduces to be knocked the injury caused.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: locking nut 1, block 2, handle 3, slide block 4, force rod 5, sleeve 6, bolt 7 of pulling pin, the first cushion 8, second cushion 9, fixed block 10, spring 11.
Detailed description of the invention
As in figure, a kind of pin pulling out device, comprise slide block 4, force rod 5, fixed block 10 and spring 11, slide block 4 is provided with through hole 12, and force rod 5 is through through hole 12, and slide block 4 can slide on force rod 5;
Force rod 5 one end is provided with block 2, and the other end is provided with bolt 7 of pulling pin, and is provided with fixed block 10, is provided with spring 11 between fixed block 10 and slide block 4 near the one end being provided with bolt 7 of pulling pin.
In preferred scheme, one end that described force rod 5 is provided with block 2 is provided with external screw thread, and block 2 is fixed on force rod 5 by being connected with external screw thread by locking nut 1.
In preferred scheme, described block 2 and the contact surface of slide block 4 are respectively equipped with the first cushion 8 and the second cushion 9.
In preferred scheme, described force rod 5 is connected by sleeve 6 with bolt 7 of pulling pin.
In preferred scheme, described sleeve 6 is provided with internal thread, and one end that force rod 5 is connected with sleeve 6 is provided with one section of external screw thread, and bolt 7 of pulling pin is provided with external screw thread, and force rod 5 and sleeve 6, sleeve 6 and pulling pin between bolt 7 is threaded connection.
Embodiment 1:
Bolt of pulling pin is utilized to be connected with the screw followed closely of waiting to pull pin, then by slide block along force rod slide downward, Compress Spring, now spring force upwards, then staff firmly moves up slide block fast, makes slide block upwards clash into block, applies a power upwards to block, cause block to drive the bolt of pulling pin bottom force rod and force rod to move up, thus complete the work of pulling pin.
