Description
Technical field
The utility model relates to rail clamping device technical fields, more particularly to a kind of labour-saving Manual rail clamping device.
Background technique
Rail clamping device can lock crane in orbit, to prevent from being slided by when unexpected thrust.Currently used folder rail
Device is broadly divided into three categories i.e. automatic rail clamping device, semi-automatic rail clamping device, Manual rail clamping device, and automatic rail clamping device stops in crane
Operation or power-off and burst storm wind in the case of can automatic work, crane cannot be prevented to slide, and they generally construct complexity,
From great, volume is big, at high cost, it is usually used in goliath；Semi-automatic rail clamping device is usually mainly electronic work, is encountered electrical
Failure or power-off when, can not Automatic-clamping, also clamped with handwheel, therefore, this rail clamping device must be electric-hand driven two-purpose
's；Manual rail clamping device, which need to manually tighten handwheel, makes its work, and operation is simple, can flexibly mount and dismount, structure is tight
It gathers, is effectively reduced production cost.
Manual rail clamping device includes left clamp and right clamp in the prior art, is provided with screw rod between left clamp and right clamp,
When crane is stopped using, bolt can be rotated, spanner is removed, turn screw rod with spanner, so that left clamp and right folder
Pincers are towards intermediary movements, to guarantee that crane will not move, after fulfiling assignment, which can be to rail to track locking
Road is clamped, but is needed during hand-operated clamping using biggish power, right even with spanner as paving assistant engineer's tool
It is unusual sweat for staff.
Therefore above-mentioned technical problem how is solved, there is very much realistic meaning to those skilled in the art.
Summary of the invention
Based on problem above, the utility model provides a kind of labour-saving Manual rail clamping device.The utility model two clampings
Plate lower part is connected by shaft right-angled intersection, using lever principle, using lesser power can grip track, utilized after clamping
The self-lock mechanism of screw thread can keep clamping of the binding clasp to track between upright bar and sleeve, press from both sides to solve hand clamping device
The problem of needing during tight using biggish power.
The utility model specifically uses following technical scheme to achieve the goals above:
A kind of labour-saving Manual rail clamping device, including upright bar and clamping plate, two clamping plate lower parts pass through shaft cross
The top of interconnection, two clamping plates has been respectively fixedly connected with connecting plate；The upright bar is equipped with external screw thread, described vertical
Also being cased on bar can be rotated up and down and with internal thread sleeve along upright bar, be equipped with bearing on the circumference face, described
Connection ring is cased on the periphery of bearing, the connection ring is fixedly connected with the connecting plate.
In the present invention, when wanting grip track, sleeve is rotated in a clockwise direction, sleeve band dynamic bearing and company
It connects ring to move downward along upright bar, to drive connecting plate to move down with connection ring contact jaw, since connecting plate and clamping plate are
It is fixedly connected, to drive the top of two dynamic clamping plates mobile close to upright bar, due under two clamping plates
Portion is to be connected by shaft, therefore the lower end of two clamping plates can be sharp after clamping in opposite directions close to upright bar to grip track
With the self-locking function of the threaded connection between upright bar and sleeve, binding clasp keeps original state to the clamping of track, automatic pine will not occur
Slack phenomenon；When track to be unclamped, sleeve is rotated counterclockwise, sleeve band dynamic bearing and connection ring are along upright bar
It moves upwards, to drive connecting plate to move up with connection ring contact jaw, to drive the top of two dynamic clamping plates
Far from upright bar, the lower end of two clamping plates can be in opposite directions far from upright bar, to unclamp track.The utility model is former using lever
Reason, using lesser power can grip track, solve hand clamping device and needed in clamping process using biggish power
Problem.
As a preferred mode, the bearing is rolling bearing, and the rolling bearing includes outer ring, inner ring and rolling
Body, the outer ring are contacted with connection ring, the inner ring and barrel contacts.
As a preferred mode, the sleeve is fixedly connected with the internal rotary body for having cavity.
As a preferred mode, rotating disk is equipped at the top of the rotary body.
As a preferred mode, the through-hole that the upright bar can be allowed to pass through is provided in the middle part of the rotating disk top surface.
As a preferred mode, the through-hole and the upright bar are excessively cooperation.
As a preferred mode, the lower end of two clamping plates is respectively equipped with clamp feet.
As a preferred mode, the thickness of the clamp feet is thicker than the thickness of the clamping plate.
The beneficial effects of the utility model are as follows:
(1) two clamping plate lower parts of the utility model are connected by shaft right-angled intersection, and using lever principle, use is smaller
Power can grip track, after clamping using between upright bar and sleeve the self-lock mechanism of screw thread binding clasp can be kept to track
It clamps, to solve the problems, such as that hand clamping device is needed in clamping process using biggish power.
(2) bearing of the utility model is rolling bearing, and the outer ring of rolling bearing is contacted with connection ring, and inner ring connects with sleeve
Touching, so that not will drive connection ring and connecting plate rotation when sleeve rotating.
(3) the utility model in connection ring by being fixedly connected with rotary body, and rotation is equipped at the top of rotary body
Disk, so that more labor-saving lighter when turnbarrel.
(4) it is provided with the through-hole that upright bar can be allowed to pass through in the middle part of the utility model rotating disk top surface, so that rotating disk and upright bar are not
It can interfere；Through-hole and upright bar are excessively cooperation, can play the role of limit to upright bar, prevent upright bar by extraneous factor
And it deflects.
(5) lower end of the utility model clamping plate is respectively equipped with clamp feet, and the thickness of clamp feet is than the thickness of clamping plate
Thickness is equivalent to and increases clamping plate, increases the contact area of clamp feet and track, so that binding clasp is easier grip track.
