Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a convenient template punching device for building construction. Background Technology
[0002] In the construction process of building projects, formwork serves as an important temporary support and shaping tool for building structures, and the drilling process is crucial. Precise and efficient formwork drilling is a key prerequisite for ensuring the installation accuracy of subsequent building components, the stability of the structure, and the overall construction progress.
[0003] Traditional formwork drilling operations in building construction face numerous problems. On the one hand, clamping and securing the formwork is extremely inconvenient. Previously, manual fixing was commonly used, which not only consumed a significant amount of manpower and time but also made it difficult to guarantee stability. Workers needed to expend considerable effort adjusting the formwork position to ensure it wouldn't wobble during drilling. Even so, in actual drilling, the formwork frequently shifted due to insecure fixing, leading to deviations in the drilling position. This not only affected the normal use of the formwork but could also result in material waste and increased construction costs. Utility Model Content
[0004] The purpose of this utility model is to provide a convenient formwork punching device for building construction projects, which solves the technical problem that the manual fixing method not only consumes a lot of manpower and time, but also makes it difficult to guarantee the stability of the fixing, thus achieving the purpose of facilitating the clamping of the formwork.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient template drilling device for building construction, comprising a base plate, an mounting plate fixedly installed on the top of the base plate, a cylinder fixedly installed on the top of the mounting plate, a driving component provided at the telescopic end of the cylinder, a drill bit provided at the output end of the driving component, a controller provided on one side of the driving component, a handle fixedly installed on the top of the driving component, a movable groove provided on one side of the base plate, and a clamping assembly provided on one side of the base plate.
[0006] Preferably, the clamping assembly includes: an adjusting component disposed inside the base plate; and a self-locking component disposed outside the adjusting component.
[0007] Preferably, the adjusting component includes: a motor, fixedly mounted on the other side of the base plate; and a rubber pad, fixedly mounted on the top of the base plate.
[0008] Preferably, the output end of the motor is provided with a threaded rod, the other end of which movably passes through the other side of the base plate and extends into the interior of the movable groove. The other end of the threaded rod is rotatably connected to a limiting square plate via a bearing. A movable plate is threadedly connected to the outer wall of the threaded rod. A connecting rod is fixedly installed on one side of the movable plate. The connecting rod is movably connected to the base plate via the movable groove. The connecting rod is slidably sleeved on the outside of the limiting square plate. A pad is fixedly installed on the top of the connecting rod.
[0009] The motor drives the threaded rod to rotate, and by utilizing the principle of threaded transmission, the movable plate can move along the axial direction of the threaded rod.
[0010] Preferably, a vertical plate is fixedly installed at the other end of the connecting rod, a fixed top plate is fixedly installed on the inner side of the vertical plate, a threaded short rod is threadedly connected to the inside of the fixed top plate, a limiting circular plate is fixedly installed at the top of the threaded short rod, a rotating block is fixedly installed at the top of the limiting circular plate, a clamping plate is rotatably connected to the bottom of the threaded short rod through a bearing, a rubber pad is fixedly installed at the bottom of the clamping plate, a sliding opening is opened inside the vertical plate, and locking holes are equidistantly opened on both sides of the vertical plate.
[0011] Rotating the rotating block can drive the limiting circular plate and the threaded short rod to rotate. Since the threaded short rod is threadedly connected to the fixed top plate, it will move axially when rotating, thereby driving the clamping plate to move up and down.
[0012] Preferably, the self-locking component includes a slider, which is fixedly mounted on one side of the clamping plate.
[0013] Preferably, the slider moves through the sliding opening and is slidably connected to the vertical plate through the sliding opening. A movable rod is fixedly installed on the outside of the slider. A connecting groove is opened on both sides of the movable rod. A guide rod is fixedly installed inside the movable rod. The movable rod is slidably connected to the outer wall of the guide rod. The movable rod is movably connected to the connecting frame through the connecting groove. A spring is sleeved on the outer wall of the guide rod.
[0014] The cooperation between the slider and the sliding opening of the vertical plate provides a stable guide for the vertical movement of the clamping plate.
[0015] Preferably, one end of the spring is fixedly connected to the movable rod, and the other end of the spring is fixedly connected to the connecting frame. The top of the connecting frame is symmetrically provided with a second sliding opening. A paddle is fixedly installed on the top of the movable rod. The paddle moves through the second sliding opening. A connecting plate is fixedly installed on the outer end of the movable rod. A locking block is fixedly installed on the inner side of the connecting plate. The locking block is locked and connected to the vertical plate through a locking hole.
[0016] The lever will cause the movable rod to move outward against the spring force, thereby causing the connecting plate and the locking block to move outward as well, and finally causing the locking block to disengage from the locking hole, thus releasing the locking of the clamping plate position.
[0017] This utility model provides a convenient formwork drilling device for building construction. It has the following beneficial effects:
[0018] (1) This utility model starts a motor, and the output end of the motor drives the threaded rod to rotate. The rotation of the threaded rod causes the movable plate to move along the axial direction of the threaded rod, which in turn drives the connecting rod, the vertical plate and the connected components to move towards the template. When the vertical plate is close to the template, the rotating block is rotated. The rotating block drives the limiting round plate and the threaded short rod to rotate. As the threaded short rod rotates, the clamping plate will move downward under the drive of the threaded short rod until the rubber pad is in close contact with the template, so as to facilitate clamping the template.
[0019] (2) By pulling the lever outward, the lever drives the movable rod to move outward. When the movable rod moves, it stretches the spring. At the same time, the movable rod drives the locking block to disengage from the locking hole through the connecting plate. After clamping is completed, the lever is released. Due to the elasticity of the spring, the movable rod and the connecting plate move inward. When the connecting plate moves, it drives the locking block to engage into the corresponding locking hole, thereby achieving the self-locking of the clamping plate position and preventing it from loosening during the drilling process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0029] Example 1:
[0030] Based on the current practice of manually fixing formwork, which is not only labor-intensive and time-consuming but also lacks stability, this utility model provides a preferred embodiment of a convenient formwork punching device for building construction projects, for example... Figure 1-4As shown: A convenient formwork drilling device for building construction includes a base plate 1, an mounting plate 2 fixedly installed on the top of the base plate 1, a cylinder 3 fixedly installed on the top of the mounting plate 2, a driving component 4 provided at the telescopic end of the cylinder 3, a drill bit 5 provided at the output end of the driving component 4, a controller 6 provided on one side of the driving component 4, a handle 7 fixedly installed on the top of the driving component 4, a movable groove opened on one side of the base plate 1, and a clamping assembly 8 provided on one side of the base plate 1. The clamping assembly 8 includes: an adjusting component 81, disposed inside the base plate 1; and a self-locking component 82, disposed outside the adjusting component 81. The adjusting component 81 includes: a motor 811, fixedly installed on the other side of the base plate 1; and a rubber pad 813, fixedly installed on the top of the base plate 1. A threaded rod 812 is provided at the output end of the motor 811, and the other end of the threaded rod 812 movably passes through the other side of the base plate 1 and extends into the movable groove. The other end of the threaded rod 812 is rotatably connected by a bearing. A limiting square plate 8115 is connected to the outer wall of a threaded long rod 812, and a movable plate 814 is threadedly connected to it. A connecting rod 815 is fixedly installed on one side of the movable plate 814. The connecting rod 815 is movably connected to the base plate 1 through a movable groove. The connecting rod 815 is slidably sleeved on the outside of the limiting square plate 8115. A pad 816 is fixedly installed on the top of the connecting rod 815. A vertical plate 817 is fixedly installed on the other end of the connecting rod 815. A fixed top plate 81 is fixedly installed on the inner side of the vertical plate 817. 8. The fixed top plate 818 is internally threaded with a threaded short rod 819. The top of the threaded short rod 819 is fixedly installed with a limiting circular plate 8111. The top of the limiting circular plate 8111 is fixedly installed with a rotating block 8112. The bottom of the threaded short rod 819 is rotatably connected to a clamping plate 8113 through a bearing. The bottom of the clamping plate 8113 is fixedly installed with a rubber pad 8114. The vertical plate 817 has a sliding opening inside. The two sides of the vertical plate 817 are respectively provided with equidistant locking holes.
[0031] Furthermore, in this embodiment, by starting motor 811, the output end of motor 811 drives the threaded rod 812 to rotate. Since the threaded rod 812 is threadedly connected to the movable plate 814, and the movable plate 814 is connected to the vertical plate 817 through the connecting rod 815, the rotation of the threaded rod 812 causes the movable plate 814 to move along the axial direction of the threaded rod 812, driving the connecting rod 815, the vertical plate 817, and the connected components to move towards the template as a whole. When the vertical plate 817 approaches the template, the rotating block 8112 is rotated, and the rotating block 8112 drives the limiting circular plate 8111 and the threaded short rod 819 to rotate. Since the threaded short rod 819 is threadedly connected to the fixed top plate 818, as the threaded short rod 819 rotates, the clamping plate 8113 will move downward under the drive of the threaded short rod 819 until the rubber pad 8114 is in close contact with the template.
[0032] Example 2:
[0033] Based on Embodiment 1, a preferred embodiment of the convenient formwork punching device for building construction provided by this utility model is as follows: Figure 1-4 As shown: The self-locking component 82 includes: a slider 821, fixedly installed on one side of the clamping plate 8113; the slider 821 movably passes through a sliding opening and is slidably connected to the vertical plate 817 through the sliding opening; a movable rod 824 is fixedly installed on the outer side of the slider 821; the movable rod 824 has connecting grooves on both sides; a guide rod 823 is fixedly installed inside the movable rod 824; the movable rod 824 is slidably connected to the outer wall of the guide rod 823; and the movable rod 824 is movably connected to the connecting frame 822 through the connecting grooves. A spring 825 is fitted on the outer wall of the guide rod 823. One end of the spring 825 is fixedly connected to the movable rod 824, and the other end of the spring 825 is fixedly connected to the connecting frame 822. The top of the connecting frame 822 is symmetrically provided with sliding openings. A paddle 826 is fixedly installed on the top of the movable rod 824. The paddle 826 moves through the sliding opening. A connecting plate 827 is fixedly installed on the outer end of the movable rod 824. A locking block 828 is fixedly installed on the inner side of the connecting plate 827. The locking block 828 is locked and connected to the vertical plate 817 through a locking hole.
[0034] Furthermore, in this embodiment, by pulling the lever 826 outward, the lever 826 drives the movable rod 824 to move outward. When the movable rod 824 moves, it stretches the spring 825. At the same time, the movable rod 824 drives the locking block 828 to disengage from the locking hole through the connecting plate 827. After clamping is completed, the lever 826 is released. Due to the elasticity of the spring 825, the movable rod 824 and the connecting plate 827 move inward. When the connecting plate 827 moves, it drives the locking block 828 to engage into the corresponding locking hole, thereby achieving self-locking of the position of the clamping plate 8113 and preventing it from loosening during the drilling process.
[0035] In use, place the template to be punched on the base plate 1, with one side of the template abutting against the rubber pad 813. Start the motor 811. The output end of the motor 811 drives the threaded rod 812 to rotate. Since the threaded rod 812 is threadedly connected to the movable plate 814, and the movable plate 814 is connected to the vertical plate 817 via the connecting rod 815, the rotation of the threaded rod 812 causes the movable plate 814 to move along the axial direction of the threaded rod 812, thereby driving the connecting rod 815, the vertical plate 817, and other components connected to it. The connected components move as a whole towards the template. When the vertical plate 817 approaches the template, the rotating block 8112 is rotated. The rotating block 8112 drives the limiting circular plate 8111 and the threaded short rod 819 to rotate. Because the threaded short rod 819 is threadedly connected to the fixed top plate 818, as the threaded short rod 819 rotates, the clamping plate 8113 will move downward under the action of the threaded short rod 819 until the rubber pad 8114 is in close contact with the template, firmly clamping the template between the base plate 1 and the clamping plate 8113. As 8113 moves downward, slider 821 slides within the sliding opening of vertical plate 817 along with clamping plate 8113, simultaneously driving movable rod 824 to move. Before clamping, pull tab 826 is pulled outward, causing movable rod 824 to move outward. During this movement, movable rod 824 stretches spring 825, and simultaneously, movable rod 824, through connecting plate 827, causes locking block 828 to disengage from locking hole. After clamping is complete, pull tab 826 is released, and due to the elasticity of spring 825, movable rod 821... The moving rod 824 and the connecting plate 827 move inward. When the connecting plate 827 moves, it drives the locking block 828 to engage in the corresponding locking hole, thereby achieving self-locking of the position of the clamping plate 8113 and preventing it from loosening during the drilling process. The controller 6 starts the drive component 4, and the output end of the drive component 4 drives the drill bit 5 to rotate at high speed. At the same time, the cylinder 3 is started, and the extension end of the cylinder 3 pushes the drive component 4 and the drill bit 5 to move downward, so as to perform drilling operations on the clamped and fixed template. The handle 7 facilitates the movement and handling of the device.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
