DETAILED DESCRIPTION

[0035] The preferred embodiment of the utility model is described below in conjunction with the accompanying drawings. It should be understood that the auxiliary device for drilling holes for reinforcing bars in floor beams and slabs described here is a preferred embodiment, which is only used to illustrate and explain the utility model and does not constitute a limitation on the utility model.

[0036] The directional terms or positional relationships such as "upper", "lower", "left", "right", "front", and "back" described in the embodiments are based on the figures in the specification of the utility model. Figure 1 , Figure 3 The orientation relationship is only for the convenience of describing the present invention and simplifying the description. It does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the content protected by the present invention.

[0037] Example 1

[0038] like Figure 1 to Figure 6 As shown, this embodiment includes a column 1, a support column 2, a clamp 3 and a jacking assembly. The column 1 is coaxially arranged with the support column 2, and the support column 2 can be slidably arranged along the axial direction of the column 1. The clamp 3 is fixed to the top of the support column 2 and is used to clamp the drilling equipment. The jacking assembly is used to drive the support column 2 to slide up and down so that the drilling equipment moves toward or away from the floor beam.

[0039] like Figure 1 As shown, in this embodiment, the column 1 includes a first column 101 and a second column 102 fixedly arranged at the top of the first column 101. The first column 101 and the second column 102 are coaxially arranged. The diameter of the second column 102 is larger than the diameter of the first column 101. The second column 102 is a steel pipe in the prior art, and its interior is a hollow structure. The support column 2 is a round steel structure, which is sleeved inside the second column 102. The up and down movement of the support column 2 is driven by the jacking assembly. Of course, in this embodiment, the column 1 can also only be provided with the second column 102.

[0040] The lifting assembly includes a first connecting rod 4, a four-link unit, and a handle;

[0041] like Figure 1 , 3 As shown in , 4, the first connecting rod 4 is fixed to the bottom end of the support column 2, and the axial direction of the first connecting rod 4 is arranged along the radial direction of the support column 2. In this embodiment, the axial direction of the first connecting rod 4 is along the front and rear directions. The jacking assembly drives the first connecting rod 4 to rise and fall, thereby raising and lowering the support column 2 and the clamp 3, so that the drilling equipment can feed the drilling or retract. In order to ensure the smooth rise and fall of the first connecting rod 4, a strip opening 103 is provided on the side wall of the second column 102. The length direction of the strip opening 103 is along the axial direction of the column 1, where the length direction refers to the up and down direction. In this embodiment, the number of the strip openings 103 is two, one is arranged on the front and rear sides of the second column 102, and the two ends of the first connecting rod 4 extend from the strip openings 103 on the front and rear sides, respectively.

[0042] like Figure 1 , 3 As shown, the four-link unit includes a first movable link 5, a second movable link 6, a third movable link 7 and a fourth movable link 8 which are hinged in pairs. The first movable link 5, the second movable link 6, the third movable link 7 and the fourth movable link 8 form a diamond structure. In this embodiment, the first movable link 5, the second movable link 6, the third movable link 7 and the fourth movable link 8 are all made of galvanized flat steel. The hinge axis of the third movable link 7 and the fourth movable link 8 is the first link 4, and the hinge point of the third movable link 7 and the fourth movable link 8 is the jacking working position. Here, the jacking working position means that when the third movable link 7 and the fourth movable link 8 move relative to each other, they can push the first link 4 to move upward to achieve jacking. Figure 3 , 4 As shown, in this embodiment, the third movable link 7 is located at the front side of the second column 102 and is hinged to the front end of the first link 4. The fourth movable link 8 is located at the rear side of the second column 102 and is hinged to the rear end of the first link 4. Here, the first link 4 is a bolt. The bolt head and the nut limit the third movable link 7 and the fourth movable link 8 respectively to prevent the third movable link 7 and the fourth movable link 8 from being separated from the screw. Figure 1 , 3 , 4 are all shown. Since the use of bolts to achieve hinged connection is a prior art, it will not be described in detail here.

[0043] like Figure 3As shown, the third movable link 7 and the first movable link 5, and the fourth movable link 8 and the second movable link 6 are hinged by bolts, but it should be noted that in this embodiment, the first movable link 5 is located at the rear side of the second column 102, and the second movable link 6 is located at the front side of the second column 102. The first movable link 5 and the second movable link 6 are hinged by the second link 9, as shown in FIG. Figure 3 , 5 As shown, the second connecting rod 9 is a hinge shaft. The second connecting rod 9 is fixed to one end of the second column 102 away from the support column 2. In this embodiment, the axial direction of the second connecting rod 9 is arranged along the radial direction of the support column 2, that is, the axial direction of the second connecting rod 9 is along the front and rear directions, and the two ends of the second connecting rod 9 extend from the front and rear strip openings 103 respectively. In this embodiment, the hinge point of the first movable connecting rod 5 and the second movable connecting rod 6 is a fixed working position. Here, the fixed working position means that the position of the second connecting rod 9 is fixed and will not move. The first movable connecting rod 5 and the second movable connecting rod 6 both use the second connecting rod 9 as the rotation center. In this embodiment, the structure of the second connecting rod 9 is the same as that of the first connecting rod 4, the difference is that the first connecting rod 4 can slide up and down, and the second connecting rod 9 is fixedly connected to the second column 102 and cannot slide. The structure of the second connecting rod 9 is not described here.

[0044] The handle is used to drive the four-bar linkage unit to move so as to lift the support column 2. The handle structure is as follows: Figure 1 As shown, the first movable link 5 extends along its axial direction to form a first extension rod 10, and the first extension rod 10 intersects with the second movable link 6; the second movable link 6 extends along its axial direction to form a second extension rod 11, and the second extension rod 11 intersects with the first movable link 5; the handle is the first extension rod 10 and the second extension rod 11. When drilling, the first extension rod 10 and the second extension rod 11 are pushed in opposite directions, that is, the first extension rod 10 is pushed to the left, and the second extension rod 11 is pushed to the right. At this time, the first movable link 5 and the second movable link 6 move relative to each other, and the third movable link 7 and the fourth movable link 8 push the first link 4 to move upward, and the drilling equipment feeds to the floor beam to achieve drilling. After the drilling is completed, the first extension rod 10 and the second extension rod 11 are pushed in opposite directions, the first link 4 moves downward, and the clamp 3 and the drilling equipment are withdrawn.

[0045] It should be noted that the four-bar linkage unit can also be set as any four-bar linkage in the prior art, as long as the lifting position of the four-bar linkage is set on the first link 4, and the fixed position of the four-bar linkage is set on the column 1, the lifting and lowering of the first link 4 and the support column 2 can be realized by manipulating the four-bar linkage. In this embodiment, the second movable link 6 and the third movable link 7 are located on the front side of the second column 102, and the first movable link 5 and the fourth movable link 8 are located on the rear side of the second column 102. The first movable link 5, the second movable link 6, the third movable link 7 and the fourth movable link 8 can also be set on the same side of the second column 102, as long as their hinged relationship can realize the lifting and lowering of the first link 4. The handle in this embodiment can also be replaced with any structure in the prior art, as long as it can drive the four-bar linkage unit to deform to realize the lifting and lowering of the first link 4 and the support column 2.

[0046] Further, such as Figure 1 , 2 As shown in Figures 3 and 4, a spring 104 is provided inside the second column 102, and the spring 104 serves as a telescopic assist structure. The fixed end of the spring 104 is fixed to the bottom of the second column 102, and the free end of the spring 104 is fixedly connected to the bottom end of the support column 2. Before drilling, since the support column 2, the clamp 3, and the drilling equipment have a certain weight, the spring 104 is in a compressed state inside the second column 102. Because there is a reaction force on the support column 2 when the spring 104 is compressed, it can support the support column 2 and prevent the support column 2 from falling to the bottom end of the second column 102. When drilling, the hand pushes the first extension rod 10 and the second extension rod 11 in opposite directions to make the first connecting rod 4 rise. At this time, the spring 104 in the compressed state acts as a thrust on the support column 2, helping the support column 2 to rise, so that the hand operation is more labor-saving. In this embodiment, the size of the spring 104 is matched with the size of the second column 102. Here, matching means that the diameter of the spring 104 is equal to the inner diameter of the second column 102. When the spring 104 is compressed or extended, the second column 102 can guide the spring 104 to prevent the spring 104 from deviating to the left or right while moving up or down; and the length of the spring 104 in the free state is equal to or greater than the length of the strip opening 103, so as to ensure that the first connecting rod 4 can be lifted to the top wall position of the strip opening 103 more effortlessly.

[0047] In this embodiment, the sum of the heights of the first column 101, the second column 102 and the support column 2 is matched with the distance from the floor beam to the ground, and here, matching means that the sum of the heights of the first column 101, the second column 102 and the support column 2 is equal to or greater than the distance from the floor beam to the ground to ensure the drilling depth. Otherwise, when the first connecting rod 4 is lifted to the top wall of the strip opening 103, the drilling equipment has not yet touched the floor beam, and drilling cannot be achieved.

[0048] In order to adapt to drilling equipment of different sizes, the clamp 3 is configured as a width-adjustable structure, specifically, as Figure 6 As shown, the clamp 3 includes a first clamp plate 31 and a second clamp plate 32 that are detachably connected. The first clamp plate 31 and the second clamp plate 32 are both made of channel steel and are both L-shaped structures. After the first clamp plate 31 and the second clamp plate 32 are assembled, the longitudinal section of the clamp 3 is U-shaped. Figure 3 As shown, a clamping space 33 for clamping the drilling equipment is formed between the first clamping plate 31 and the second clamping plate 32. In this embodiment, the first clamping plate 31 is fixed to the top of the support column 2. The first clamping plate 31 is provided with a strip slot 311 along the front and rear directions. The second clamping plate 32 is provided with a strip plug 321 adapted to the strip slot 311. The plug 321 slides forward and backward in the slot 311 to form a clamping space 33 of different widths, which can clamp drilling equipment of different sizes. A strip hole is provided at the position corresponding to the slot 311 on the first clamping plate 31. The strip hole extends along the front and rear directions. The strip hole is connected to the slot 311. Correspondingly, a strip hole is also provided on the plug 321. When the size of the clamping space 33 is adapted to the drilling equipment, the second clamping plate 32 is fastened to the support column 2 to achieve fixation after the strip hole, the slot 311, and the plug 321 are penetrated by bolts, and then the drilling equipment is clamped in. Here, the width refers to the distance between the clamp 3 in the front and rear directions.

[0049] Further, such as Figure 1 , 3 As shown, a support is provided at the bottom of the first column 101 , and the support includes a positioning base plate 12 and a plurality of legs 13 .

[0050] In this embodiment, the positioning base plate 12 is a steel plate, which is fixed to the bottom of the column 1. When drilling, the drilling position can be vertically positioned by the positioning base plate 12. The legs 13 play a role of lateral support for the first column 101, making the overall device more stable on the ground. In this embodiment, the legs 13 are made of flat steel, one end of which is fixed to the first column 101 by bolts, and the other end is set on the ground. The legs 13 can also be made of angle steel in the prior art. In this embodiment, two legs 13 are provided, one each on the front and rear sides of the first column 101. The number of legs 13 can also be selected as three, four or other numbers.

[0051] In the wall masonry project, the reinforcement of the concrete structural column needs to adopt the secondary reinforcement technology, and the reinforcement method is to implant anchoring steel bars at the ground position and the corresponding floor beam position. Drilling is required before the reinforcement is implanted. The operation process is as follows: according to the construction drawings, the structural column is laid out on the ground to determine its position, and the drilling position where the reinforcement needs to be planted is marked. The positioning base plate 12 in the device is used to align the bottom reinforcement hole. Because the device is a vertical rod structure, the upper and lower holes can be guaranteed to be the same verticality after the bottom is centered. Then operate the first extension rod 10 and the second extension rod 11, so that the four-bar unit drives the first connecting rod 4, the support column 2, and the drilling equipment to move upward to complete the drilling. The device is used to assist manual drilling. The operator can complete it while standing on the ground without climbing. The device is a vertical structure, and the drilling equipment can only move vertically, which ensures the accuracy of the drilling and avoids the problem of deviation in the drilling position caused by manual hand-held drilling equipment. The device is easy to operate, efficient, and safe.

[0052] Example 2

[0053] like Figure 7 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except that the top of the support column 2 is detachably provided with an extension column 14 to meet the needs of drilling holes in floor beams of different heights. The extension column 14 is a round steel structure, coaxial with the support column 2, with an internal threaded hole at the top of the support column 2, and an external thread at the bottom of the extension column 14, and the extension column 14 is threadedly fixed to the support column 2. The sum of the heights of the column 1, the support column 2 and the extension column 14 is adapted to the distance from the floor beam to the ground. Adaptation here means that the sum of the heights of the column 1, the support column 2 and the extension column 14 is equal to or greater than the distance from the floor beam to the ground, so as to ensure that the drilling equipment can drill holes smoothly, otherwise, when the first connecting rod 4 is lifted to the top wall of the strip opening 103, the drilling equipment has not yet touched the floor beam, and drilling cannot be achieved. It should be supplemented that, according to the actual distance from the floor beam to the ground, the number of extension columns 14 can be selected to be one, two or other numbers. In this embodiment, the clamp 3 is fixed to the top of the extension column 14, and its fixing method is the same as the fixing method of the clamp 3 to the top of the support column 2 in Example 1; other structures are exactly the same as Example 1 and will not be elaborated in detail in this embodiment.

[0054] The usage process of this embodiment refers to Embodiment 1.
