[0002] Concrete coring machine is one of the most widely used inspection equipment in road engineering inspection, mainly used for coring on asphalt pavement and limestone pavement. For example, the authorization announcement number CN206369640U, named a utility model patent for a pavement coring machine, includes a main pulley, a secondary pulley, a fan-shaped plate, a first mounting hole, a second mounting hole and a fixing rod, etc. When the pavement coring machine cores the pavement, the fixing rod that is simultaneously penetrated in the first mounting hole and the second mounting hole is taken out. At this time, due to the gravity of the pavement coring machine itself, the pulley seat rotates upward, and the secondary pulley also rotates upward under the drive of the pulley seat until the support base contacts the pavement. At this time, the main pulley of the pavement coring machine and the end away from the main pulley simultaneously contact the pavement, so that the coring barrel of the pavement coring machine is not easy to shake.

[0003] When the above device is used on an uneven road surface, in order to keep the core drilling machine drill bit vertical to the coring point of the road surface (so that the structural layers of the core sample taken out are horizontal and the measured data can be more accurate), the staff needs to pad the bottom of the support base to make the support base horizontal, which is a time-consuming and labor-intensive process.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] In order to solve the technical problem of manually leveling a base which is time-consuming and laborious, the utility model provides a coring machine bracket which can make leveling the base faster and easier.

[0028] It should be noted that the coring machine bracket described in the utility model is used for but not limited to coring machines, etc. For the convenience of explanation, in the utility model, only an example of a coring machine bracket being applied to a coring machine device is used for explanation, and the principle of a coring machine bracket being applied to other types of equipment is substantially the same as the principle applied to the coring machine device, which will not be repeated here.

[0029] See also Figure 1 - Figure 4 A coring machine bracket includes a base 1 and a leveling mechanism 2. The base 1 includes a pair of cross beams 11 and a pair of longitudinal beams 12. The top of the cross beam 11 is provided with a groove 111, and the bottom of the groove 111 is provided with a clearance groove 112. The leveling mechanism 2 includes a hinge block 21, a first screw rod 23 and a roller 22. The hinge block 21 is located above the clearance groove 112 and is hinged to the two inner walls opposite to the groove 111. The hinge block 21 is provided with a threaded hole 211. The first screw rod 23 is threadedly sleeved in the threaded hole 211, and the end of the first screw rod 23 is rotatably connected to the roller 22.

[0030] In this embodiment, in the first state, the hinge block 21 is rotated so that the first screw 23 is embedded in the groove 111 and is parallel to the crossbeam 11, and the arc surface of the roller 22 supports the base 1, so that the base 1 can move by the rotation of the roller 22;

[0031] In the second state, when the hinge block 21 is rotated to the clearance groove 112 so that the first screw rod 23 is disengaged from the groove 111 and is perpendicular to the beam 11, the side (plane) of the roller 22 supports the base 1. The staff can adjust the height of the hinge block 21 and the beam 11 by rotating the first screw rod 23, thereby realizing the horizontal adjustment of the base 1. Compared with the method of manually leveling the base 1, the utility model saves time and effort.

[0032] First, use the roller 22 to move the base 1 to a preset position; then, rotate the hinge block 21 in the direction of the clearance groove 112 until the side (plane) of the roller 22 abuts against the ground. At this time, the first screw 23 rotates along with the hinge block 21 until the first screw 23 and the beam 11 are vertical; finally, the staff adjusts the height of the hinge block 21 by rotating the first screw 23, thereby achieving the purpose of adjusting the base 1.

[0033] In one embodiment, see Figure 3 The tops of the two beams 11 are provided with grooves 111 , the ends of the two grooves 111 are provided with clearance grooves 112 , and the leveling mechanisms 2 are divided into four groups, and each leveling mechanism 2 is located above each clearance groove 112 .

[0034] In this embodiment, a square frame base 1 is assembled from a pair of horizontal beams 11 and a pair of longitudinal beams 12, and the four ends of the two horizontal beams 11 extend out of the two longitudinal beams 12. Four leveling mechanisms 2 are respectively connected to the four corners of the square frame base 1, so that the staff can adjust the level of the base 1 through different leveling mechanisms 2.

[0035] In one embodiment, see Figure 4 One end of the first screw rod 23 away from the roller 22 is fixedly connected to a first handle 231 .

[0036] In this embodiment, when the roller 22 is in the supporting state, the first screw rod 23 is vertical to the beam 11 , and the first handle 231 is provided to facilitate the staff to rotate the first screw rod 23 through the first handle 231 , thereby achieving the purpose of adjusting the base 1 .

[0037] In one embodiment, see Figure 3 The middle of the groove 111 is fixedly connected to the limiting block 13 , the limiting block 13 defines a limiting hole 131 , and the top of the first handle 231 is provided with a protrusion 2311 , which is embedded in the limiting hole 131 .

[0038] In this embodiment, in order to prevent the first screw rod 23 from rotating due to vibration and thus affecting the positioning of the roller 22, the protrusion 2311 is embedded in the limiting hole 131, which effectively prevents the first handle 231 from rotating and ensures the normal operation of the roller 22.

[0039] In one embodiment, see Figure 2 A pressure cover 14 is hinged on the top of the groove 111 .

[0040] In this embodiment, the pressure cover 14 cooperates with the bottom of the groove 111 to clamp the first screw rod 23, so that the roller 22 at the end of the first screw rod 23 will not shake during the rotation process.

[0041] In one embodiment, see Figure 2 A rubber pad 141 is fixedly connected to one side of the pressure cover 14 facing the groove 111 .

[0042] In this embodiment, the function of the rubber pad 141 is to prevent the gland 14 from being rigidly connected to the first screw rod 23 , which would cause the first screw rod 23 to be squeezed and deformed by the gland 14 .

[0043] In one embodiment, see Figure 1 A second handle 142 is provided on the top of the gland 14 .

[0044] In this embodiment, the second handle 142 is used to facilitate the staff to grasp it. The staff drives the pressure cover 14 to flip by grasping the second handle 142.

[0045] In one embodiment, see Figure 1 A lower flat plate 121 is fixedly connected to the top of the longitudinal beam 12 .

[0046] In this embodiment, the lower plate 121 is used to support the coring machine.

[0047] In one embodiment, see Figure 1 A plurality of support rods 122 are fixedly connected to the top of the lower plate 121 , and an upper plate 123 is fixedly connected to the top of each support rod 122 .

[0048] In this embodiment, the top of the upper plate 123 is fixedly connected to the first motor 33 , and the first screw rod 23 passes downward through the upper plate 123 and is threadedly connected to the lifting plate 31 , and the lifting plate 31 can move up and down along the length direction of the support rod 122 .

[0049] In one embodiment, see Figure 1 The support rod 122 sliding sleeve is provided with a drilling mechanism 3.

[0050] In this embodiment, the drilling mechanism 3 includes a lifting plate 31, a second screw rod 32, a first motor 33, a coring barrel 34 and a second motor 35. The lifting plate 31 of the second motor 35 is slidably sleeved on the support rod 122. The second screw rod 32 is threadedly connected to the lifting plate 31, so that when the first motor 33 drives the second screw rod 32 to rotate, it can drive the lifting plate 31 to rise and fall along the length direction of the support rod 122, and then connect with the lifting plate 31 through the coring barrel 34 and the second motor 35. The second motor 35 drives the coring barrel 34 to rotate, so that the coring barrel 34 drills deeper and deeper into the ground.

[0051] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

[0052] First, use the roller 22 to move the base 1 to a preset position; then, grab the second handle 142 and open the pressure cover 14; then, grab the first screw 23 and turn it in the direction away from the groove 111, and the hinge block 21 rotates in the direction of the clearance groove 112, so that the first screw 23 is separated from the groove 111, until the first screw 23 and the beam 11 are in a vertical state, and the side (plane) of the roller 22 is in contact with the ground, thereby realizing a structure in which the roller 22 and the bracket are combined into one. The staff can adjust the roller 22 to different shapes according to the required situation. state; then, the staff rotates the first screw 23 through the first handle 231. Since the first screw 23 is threadedly connected to the threaded hole 211, and the side (plane) of the roller 22 is in contact with the ground and cannot move, the hinge block 21 will drive the end of the beam 11 to rise and fall together. By adjusting the four corners of the base 1, the purpose of horizontally adjusting the base 1 can be achieved. During the whole process, the staff does not need to find something to pad under the base 1, which effectively improves the efficiency of leveling the base 1; finally, the drilling mechanism 3 is started, and the coring machine starts working.

[0053] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
