Abstract
The utility model discloses an anti-rotation bolt for a revolving platform of a crawler crane. The bolt (3) is provided with a lateral pin (5), and a bolt upper seat (2) is provided with at least one axial deep groove (6) and at least one axial shallow groove (7). When the lateral pin (5) on the bolt (3) enters into the bottom part of the axial deep groove (6), the bolt (3) can be inserted into a bolt lower seat (1). When the lateral pin (5) on the bolt (3) enters into the bottom part of the axial shallow groove (7), the bolt (3) leaves from the bolt lower seat (1). The bolt (3) is provided with a movable handle (4). In the process of transporting and long-distance walking of the crawler crane, the anti-rotation bolt for the revolving platform of the crawler crane can effectively lock a loading platform and protect a revolving brake against being damaged. At the same time, the occupied space of the anti-rotation bolt in a cab is very small, and the plugging of lock pins is convenient.
Description
Technical field
The utility model relates to a kind of crawler crane turn table anti-rotation latch.
Background technology
Crawler crane claims that again tank hangs, and because of the big pressure of its track area is low, can use more and more widely in recent years soft, muddy and very do not walk on the flat ground surface.
Crawler crane can be under rated load weight 80% situation on smooth and hard ground, and lift heavy slowly travels, and get on the bus can 360 degree revolution operations.Long distance walking or time spent not for a long time in order to avoid trainstop destroys, must be connected as a single entity turn table and main frame, and revolution prevents to get on the bus.And the anti-rotation latch can effectively will be got on the bus locking, and turn table is fixed on the walker, effectively protects trainstop.
The utility model content
Technical problem to be solved in the utility model provides a kind of in the crawler crane transportation and growing apart from walking process; can effectively pin the platform of getting on the bus; the protection trainstop is not damaged; while anti-rotation latch takes up space very little in driver's cab, and the plug lock pin is crawler crane turn table anti-rotation latch easily.
In order to solve the problems of the technologies described above, the crawler crane turn table anti-rotation latch that the utility model adopts, comprise following of latch, the latch seat of honour, latch, on described latch, be provided with lateral pin, on the described latch seat of honour, be provided with at least one axial deep trouth and at least one axial shallow slot, described latch can be inserted in following of the described latch when lateral pin on the described latch entered into the bottom of described axial deep trouth, described latch broke away from described latch following 1 when the lateral pin on the described latch entered into the bottom of described axial shallow slot, and described latch is provided with a free handle.
Adopt the crawler crane turn table anti-rotation latch of technique scheme, following of latch is welded on the walker, and the latch seat of honour is welded on the turn table, plugs latch, and the turn table locking is extracted latch, the turn table release.One free handle is arranged on the latch, plug latch after, on the free handle lodging plane in driver's cab, latch takes up space especially little in driver's cab, has improved the driver's operation traveling comfort.
In sum; the utility model is a kind of in the crawler crane transportation and growing apart from walking process; can effectively pin the platform of getting on the bus; the protection trainstop is not damaged; while anti-rotation latch takes up space very little in driver's cab, and the plug lock pin is crawler crane turn table anti-rotation latch easily.
Description of drawings
Fig. 1 is a latch assembly assembly drowing (lockup state);
Fig. 2 is the latch outside drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, on latch 3, axially be arranged with lateral pin 5, on the latch seat of honour 2, axially be arranged with two axial deep trouths 6 and two axial shallow slots 7, latch 3 can be inserted in following 1 of the latch when lateral pin 5 on the latch 3 entered into the bottom of axial deep trouth 6, latch 3 broke away from latches following 1 when the lateral pin 5 on the latch 3 entered into the bottom of axial shallow slot 7, and latch 3 is provided with a free handle 4.
Referring to Fig. 1 and Fig. 2, following 1 of latch is welded on the walker, the latch seat of honour 2 is welded on the turn table, plug latch 3, latch 3 can be inserted in following 1 of the latch when lateral pin 5 on the latch 3 entered into the bottom of axial deep trouth 6, and the turn table locking is extracted latch 3, latch 3 broke away from latches following 1, the turn table release when lateral pin 5 on the latch 3 entered into the bottom of axial shallow slot 7.One free handle 4 is arranged on the latch 3, plug latch 3 after, on the planes of free handle 4 lodging in driver's cab, latch 3 takes up space especially little in driver's cab, has improved the driver's operation traveling comfort.
