Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: 1. a mounting frame; 11. mounting a disc; 12. a strut; 121. a base plate; 13. a fixed pulley; 14. a winch; 141. a hand wheel; 2. a core sample clamp; 21. a handle; 22. a clamping bar; 23. a connecting chain; 3. a zipper.

Detailed Description

The present invention will be described in further detail with reference to fig. 1.

The embodiment of the utility model discloses road surface concrete bores core appearance and presss from both sides, as shown in fig. 1, including mounting bracket 1, mounting bracket 1 is including the mounting disc 11 that is circular setting, and the circumference interval sets up in many spinal branchs pole 12 at mounting disc 11 side border, in this embodiment, the quantity of branch 12 is preferably three, the top of branch 12 articulates at the border of mounting disc 11, the bottom butt of branch 12 is in road surface, need not rotate branch 12 at ordinary times and accomodate together, thereby reduce the space and occupy, and simultaneously, in order to reduce the pressure of branch 12 bottom to road surface, the welding of the bottom of branch 12 has backing plate 121, backing plate 121 laminates with road surface mutually.

Referring to fig. 1, be provided with core appearance on the mounting bracket 1 and press from both sides 2, core appearance presss from both sides 2 and is located the mounting disc 11 under, and core appearance presss from both sides 2 and includes two handles 21, and two handles 21 cross setting mutually, and the cross section of two handles 21 is connected through articulated, and the equal integrated into one piece in bottom end tip of two handles 21 has clamping bar 22, after boring the core to the road, during the sample, clamping bar 22 stretches into in the gap between road and the core appearance. Simultaneously, be connected with connecting chain 23 between the other end tip of two handles 21, the one end fixed connection of connecting chain 23 in one of them handle 21, the other end fixed connection of connecting chain 23 in another handle 21, vertically be provided with zip fastener 3 on the mounting bracket 1, the bottom fixed connection of zip fastener 3 is in the middle part of connecting chain 23, the lower fixed surface of mounting disc 11 installs fixed pulley 13, fixed pulley 13 is located directly over core appearance presss from both sides 2, zip fastener 3 wears around fixed pulley 13.
