Description

Upper-hanging cross arm

Technical Field

The utility model belongs to the technical field of the whole railway roadbed switch construction equipment of subway, especially, go up formula cross arm that hangs.

Background

The short tie bars at the slide plate in the range of the turnout switch are larger, longer, heavier and different in length, the outer fasteners are connected with the steel rails of the tie rails by the light, and the inner slide plate can drop and hang in the air, so that the switch rail is subjected to the phenomenon of an empty hanging plate.

As shown in fig. 1, in the conventional construction process, after a jack 102 is used for jacking a switch tie 103, 2-3 self-made adjustable screws are arranged below the switch tie 103, and a slide plate 104 is adjusted to be closely attached to a switch rail. In the method, the adjusting screw is finally poured in the concrete and cannot be recycled, so that the screw is wasted. Meanwhile, the screw is arranged below the short switch tie, which causes the operation to be very inconvenient.

Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings.

As shown with reference to fig. 2 and 3. A top-hung cross arm, the cross arm 204 comprising: a cross beam 205, which is erected above two parallel rails 212 at the point of the turnout switch to be adjusted. And one end of each hook 206 is connected with the cross beam 205, and the other end of each hook 206 is hooked on the slide plate 210 to be adjusted.

Through the structural arrangement of the cross arm 204, when a user adjusts the position of the slide plate 210, the position of the slide plate 210 can be quickly adjusted only by adjusting the positions of the two lifting hooks 206 in the cross arm 204 in the vertical direction. The position of the slide chair 210 is prevented from being adjusted in a manner that the short switch sleeper is jacked by a jack and a screw in a traditional adjusting mode, the adjusting efficiency is greatly improved, and meanwhile, the waste of adjusting screws is avoided.

Preferably, the hook 206 comprises: the outer wall of the suspension rod 207 is provided with a thread structure and penetrates through a through hole preset on the cross beam 205; one end of the hook 209 is connected to the hanging rod 207, and the other end of the hook 209 is hooked to the slide plate 210 to be adjusted; the internal thread of the adjusting nut 208 is matched with the external thread of the suspension rod 207, the adjusting nut 208 is sleeved on the top of the suspension rod 207, and the size of the adjusting nut 208 is larger than the diameter of the through hole on the cross beam 205.

Through the structural arrangement of the hanger rod 207, a user can adjust the position of the slide plate 210 in the vertical direction by screwing the adjusting nut 208. Namely, the adjustment structure can conveniently and quickly complete the position adjustment of the slide chair 210. Meanwhile, the subsequent recycling of the cross arm 204 device is not affected.

Further, the hook 206 may also be implemented in a mode such as a take-up winch coupled with the hook 209. The pattern of the hanger hook 206 with the hanger rod 207 coupled to the hanger hook 209 is only a preferred embodiment.

Preferably, the hanger 209 is rotatable relative to the connection of the hanger 209 and the hanger bar 207. Through this connected mode setting for couple 209 can carry out the rotation of certain angle, more is favorable to couple 209 to hook into slide plate 210 fast, thereby has promoted the operating efficiency of device.

Preferably, the cross beam 205 may be a channel steel. The high strength channel steel helps promote the structural stability or life of this cross arm 204.

The utility model discloses a work flow: the cross beam 205 of the present cross arm 204 structure is erected over two parallel rails 212 at the point of the turnout switch to be adjusted. The adjusting nut 208 on the hook 206 is loosened, so that the hanger rod 207 moves downwards until reaching a proper position, the hook 209 at the bottom end of the hanger rod 207 is hooked in the slide plate 210 to be adjusted, the adjusting nut 208 is tightened, so that the hanger rod 207 drives one end of the slide plate 210 to move upwards, until the leveling rod 211 arranged on the surface of the slide plate 210 displays that the slide plate 210 is in a horizontal state, the adjusting nut 208 is stopped being screwed, and the position locking of the slide plate 210 is completed. When the slide plate 210 is in the horizontal state, the slide plate 210 and the bottom end of the switch rail 213 are in the close contact state. Then, when the position adjustment of the slide board 210 is completed, the position adjustment of the associated tie bar is completed. At this time, the track bed is poured, and the poured track bed does not cause the bottom of the turnout sleeper to sink, so that the switch rail 213 has an empty hanging plate phenomenon.

Furthermore, each roof truss of the upper-hanging cross arm is integrated by 1 cross beam 205 and 2 hooks 206. The cross arm 204 is arranged on the top of the basic rail of the switch and hooks each slide plate 210 and the connecting bolt on the inner side of the short rail pillow thereof respectively, so that each slide plate 210 is adjusted to the horizontal position to be closely attached to the switch rail 213, the close attachment adjustment operation of the slide plates 210 is quite convenient by adopting the method, and the phenomenon of empty hanging plates can not occur. Meanwhile, the upper hanging type cross arm is convenient to install and dismantle, and can be repeatedly used for many times, so that the construction cost is effectively saved.

The aforesaid the utility model discloses basic embodiment and each further alternative can the independent assortment in order to form a plurality of embodiments, is the utility model discloses can adopt and claim the embodiment of protection. In the scheme of the utility model, each selection example can be combined with any other basic examples and selection examples at will.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
