Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, in particular to a template pulling and opening hole device. Background Art

[0002] Building formwork is a temporary supporting structure that is manufactured according to design requirements to shape concrete structures and components into specified positions and geometric dimensions. Concrete is poured inside the formwork to form the concrete and steel bars into shape to construct a building.

[0003] In construction, due to the poor lateral support of the longitudinal support formwork, if concrete is poured directly into the formwork, the pressure of the concrete will exceed the lateral support of the formwork, causing the formwork to bulge at the least, resulting in an uneven surface of the building. In severe cases, the formwork will crack and cause safety accidents. Therefore, in order to ensure the lateral support of the formwork, tension holes must be opened on the surface of the formwork and tension bolts must be used to improve the support of the formwork.

[0004] During construction, there are two ways to drill holes in the formwork. If you drill holes in the unsupported formwork first and then support the formwork, the workload can be reduced, but there will be problems with mismatched hole positions, resulting in waste formwork. Therefore, in order to improve stability, it is generally practiced to support the formwork first and then drill holes.

[0005] Through work summary, it was found that after supporting the formwork, carpenters marked the lines and used electric drills to drill holes in the formwork. Sometimes, due to operational problems, the holes would be crooked, resulting in the inability to align the tension bolts. The holes had to be blocked and reopened later. Moreover, during work, there were certain errors in the grasp of the spacing between the holes, resulting in mismatch between the tension bolts and the supporting pipes. Therefore, a hole-drilling device that can improve efficiency and reduce errors was designed to solve the above problems. Utility Model Content

[0027] In this utility model:

[0028] Reference Figure 1-2 A template pulling and opening hole device includes a support base 1, with hydraulic support legs 101 fixedly installed around the support base 1, and ball-head support feet 102 provided at the telescopic ends of the hydraulic support legs 101.

The adjustment stroke of the hand-cranked screw rod 301 is 20-80CM. The hand-cranked screw rod 301 is rotated by the handle, so that the slider and the screw rod are engaged, and the X-axis guide rod 302 is cooperated to make the Z-axis slide 4 move, thereby adjusting the position of the punching, and the locking bolt can lock the handle to prevent the hand-cranked screw rod 301 from rotating.

[0031] A punching assembly capable of Z-axis movement is installed on the X-axis slide 3;

[0032] The punching assembly includes a Z-axis slide 4, a Z-axis screw guide rail 401, a Z-axis guide rod 402, a motor 5, and a drill rod 501, wherein the X-axis slide 3 is fixedly installed with the Z-axis slide 4 through a slider, the Z-axis slide 4 is equipped with a Z-axis screw guide rail 401 and a Z-axis guide rod 402, the Z-axis slide 4 is fixedly installed with the motor 5 through the slider, the motor 5 is installed with the drill rod 501 through the output shaft, and the output shaft of the motor 5 is an inner square structure, which is movably connected to the tail end of the drill rod 501, and the inner square structure can be used to replace drill rods 501 of different sizes.

[0033] Furthermore, the Y-axis guide rod 202 , the X-axis guide rod 302 , and the Z-axis guide rod 402 are all cylindrical.

[0034] There are two X-axis slides 3, which are symmetrically arranged to increase the efficiency of the number of punching holes. Example

[0035] Reference Figure 3-5 In addition to the embodiment in which the adjustment mechanism is provided with an X-axis slide 3 installed on the Y-axis slide 2 through a slider, an X-axis guide rod 302 is fixedly installed inside the X-axis slide 3, and a hand screw rod 301 is rotatably connected to the inside of the X-axis slide 3 near the bottom of the X-axis guide rod 302, there is another embodiment:

[0036] The adjustment mechanism includes a central gear 6, an adjustment handle 601, a linkage shaft 602, a positioning protrusion 603, a rack 7, and a tension spring 8;

[0037] The interior of the X-axis slide 3 is rotatably connected to a linkage shaft 602 through a bearing. A central gear 6 is fixedly installed on one end of the linkage shaft 602, and an adjustment handle 601 is slidably connected to the other end of the linkage shaft 602. A spring is provided at the axis of the adjustment handle 601 and the linkage shaft 602. The adjustment handle 601 is disc-shaped, and a positioning protrusion 603 is integrated on the inner surface; the positioning protrusion 603 fits into the groove on the surface of the X-axis slide 3.

[0038] A rack 7 is slidably connected to the inside of the X-axis slide 3 through a guide rail, and there are two racks 7, which are symmetrically arranged up and down, and the other side of the rack 7 is connected to the Z-axis slide 4.

The locking bolt can lock the handle to prevent the hand crank screw 301 from rotating. At the same time, another embodiment can also be used. First, pull the adjusting handle 601 to cancel the force on the positioning protrusion 603, and then rotate the adjusting handle 601 to link the central gear 6. The central gear 6 drives the rack 7 to move, and then links the two Z-axis slides 4 to move. Compared with the first embodiment, the adjustment of the Z-axis slide 4 is synchronous adjustment to ensure that the displacement distance of the Z-axis slide 4 is the same, which is labor-saving and has high accuracy.

[0043] Next, the output shaft of the motor 5 is an inner square structure, which is movably connected to the tail end of the drill rod 501.
