Detailed Description
As shown in the attached drawings 1-4, the invention is used for being installed on a side plate of a paver, and mainly comprises two fixed supports 1 installed on a side baffle plate of the paver, connecting rods rotatably arranged on the fixed supports 1 through rotating shaft structures respectively, and guide beams 4 arranged at the bottoms of two railings, wherein steel wires 5 are arranged on the guide beams 4, and longitudinal slope instruments 6 are slidably arranged on the steel wires 5. The side wall of the front end of the guide beam and the advancing direction of the paver form an acute angle, preferably 45 degrees, so that the impact action of the lower bearing layer on the guide beam can be reduced.
The guide beam 4 is made of seamless steel pipes, one end or two ends of each seamless steel pipe are provided with sealing covers, the length of the guide beam 4 is 4-6 m, and fine sand can be filled into the guide beam 4 on site in order to provide the weight of the guide beam 4. The fine sand is poured out in the transportation process, so that the difficulty in the transportation process can be reduced.
The rotating shaft structure comprises a base shaft 201 rotatably arranged on the fixed support 1, an outer cylinder 207 sleeved outside the base shaft 201 and a sleeve 208 arranged outside the outer cylinder 207 in a clearance fit manner, the left end of the base shaft 201 penetrates through the fixed support 1, the base shaft 201 is fixed on the fixed support 1 through a bolt, and other modes can be adopted for connection as long as the base shaft 201 can be ensured to rotate on the fixed support 1. The outer side wall of the base shaft 201 and the inner side wall of the outer cylinder 207 are provided with threads which are matched with each other, the outer side wall and the inner side wall are connected through the threads, meanwhile, in order to prevent the outer cylinder 207 from rotating randomly, a pin shaft 210 is arranged on one side, close to the fixed support 1, of the outer cylinder 207, a through hole corresponding to the pin shaft 210 is formed in the fixed support 1, and the pin shaft 210 penetrates through the through hole and is used for limiting the rotation of the outer cylinder 207 so that the outer cylinder 207 can only horizontally.
A limiting groove is formed on the right end side wall of the outer cylinder 207, and the sleeve 208 is arranged in the limiting groove, so that the sleeve 208 can move along the axial direction of the outer cylinder 207 along with the outer cylinder 207.
In order to adjust the position of the outer cylinder 207, a corresponding structure is required to rotate the base shaft 201, and since the outer cylinder 207 can only move axially under the action of the pin shaft 210, when the base shaft 201 rotates, the outer cylinder 207 can only move axially, which brings the sleeve 208 to move, so that the distance between the guide beam 4 and the paver can be adjusted.
The structure for rotating the base shaft 201 is as follows: the side wall of the base shaft 201 is provided with two opposite side positions with limiting grooves 203, the base shaft 201 is provided with an adjusting rod 205, the inner side end of the adjusting rod 205 is provided with a clamping plate 204, and two ends of the clamping plate 204 are respectively clamped in the corresponding limiting grooves 203. Like this, when adjusting pole 205 rotation, because cardboard 204 card is put in spacing groove 203, alright rotate with driving base shaft 201.
In order to prevent the relative rotation between the base shaft 201 and the outer cylinder 207 caused by mechanical vibration in the construction process, an adjusting arm 206 is arranged at the outer side end of the adjusting rod 205, and a clamping groove 209 for clamping with the adjusting arm 206 is arranged on the side wall of the outer side end of the outer cylinder 207. Therefore, after the position of the outer cylinder 207 is adjusted in place, the adjusting arm 206 is pushed inwards, and the adjusting arm 206 is clamped in the clamping groove 209, so that the relative rotation between the base shaft 201 and the outer cylinder 207 can be limited, thereby realizing the positioning and preventing the outer cylinder 207 from moving axially.
The connecting rod includes first connecting rod 3 and second connecting rod 7, the upper end and the sleeve 208 fixed connection of first connecting rod 3, the lower extreme is connected through the pivot with the upper end of second connecting rod 7, and the lower extreme and the nose girder 4 of second connecting rod 7 are connected through the pivot.
The steel wire 5 is arranged on the guide beam 4 through the steel wire support 8, the wire tensioning device is arranged on the steel wire support 8, when the steel wire 5 becomes loose, the steel wire can be tensioned again through the wire tensioning device, the wire tensioning device is more embodied in the prior art, and the description is omitted here.
The invention reduces the measurement and paving manpower needed in the construction process, and simultaneously, the paving flatness is also greatly improved.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
