Description

Technical Field

[0001] The utility model relates to the technical field of beam formwork construction, and particularly relates to a hole punching device for building beam formwork. Background Art

[0002] At present, during the construction of traditional large beam formwork, usually after the beam formwork is erected, construction workers hold electric tools on the support frame to punch holes in the beam formwork. The construction operation space is small, the operation is difficult, and there is no operating platform on the support frame. It is necessary to operate the hole punching tool with one hand, which is relatively dangerous, and it is impossible to ensure that the hole positions on both sides of the formwork are consistent.

[0003] After retrieval, the patent number is CN117340993A, which discloses a synchronous hole punching device and construction method for large-section beam side formwork, including a stepping mechanism at the front end and a hole punching mechanism at the rear end. The stepping mechanism and the hole punching mechanism are connected by an intermediate rod group; the stepping mechanism includes a stepping rotating shaft, the middle of the stepping rotating shaft is rotatably connected with a first pivot connecting seat, and each end of the stepping rotating shaft is provided with a three-rod frame mechanism. The three-rod frame mechanism has three supporting feet circumferentially distributed around the central axis of the stepping rotating shaft; the hole punching mechanism includes two groups of double-rod vertical rail frames symmetrically distributed left and right. A hole punch with the drill bit facing outwards is installed on the double-rod vertical rail frame, and the two double-rod vertical rail frames on both sides are movably connected by a vertical rail distance adjusting rod group; through the combined use of the stepping mechanism and the hole punching mechanism, the probability of positioning errors is reduced. At the same time, an innovative technological method is invented. Through continuous rolling construction steps, holes are accurately and effectively punched, and at the same time, it can ensure that the hole positions on both sides of the formwork are completely consistent. However, when operating this device, it is necessary to adjust the stepping distance of the three-rod frame mechanism rotating one-third of a week, and it is also necessary to push the handles on both sides outwards to drive the hole punch to feed laterally to complete the hole punching operation on both sides of the side formwork. The operation is cumbersome and time-consuming. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a hole punching device for building beam formwork aiming at the above deficiencies, which overcomes the defects of the existing cumbersome operation and time-consuming and laborious; and realizes the purpose of convenient operation and time-saving and labor-saving.

[0005] To solve the above technical problems, the technical solution of the utility model is: a hole punching device for building beam formwork, characterized in that: it includes a telescopic support, a driving motor is arranged on the upper part of the telescopic support, the output end of the driving motor is connected with a first driving screw rod, a first nut is fitted on the first driving screw rod, the bottom of the first driving screw rod is fixedly connected with a second driving screw rod, and a second nut is fitted on the second driving screw rod;

[0006] A connecting rod is arranged between the first nut and the second nut;

[0007] The top of the telescopic support is provided with a handle, and the bottom of the handle is provided with a hole opener switch and a forward and reverse switch.

[0008] Furthermore, the connecting rod includes a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod. One end of the first connecting rod is hinged to the first nut, and the other end of the first connecting rod is hinged with a second fixing seat. A second hole opener is fixedly arranged on the second fixing seat.

[0009] One end of the third connecting rod is hinged to the first nut, and the other end of the third connecting rod is hinged with a first fixing seat. A first hole opener is fixedly arranged on the first fixing seat.

[0010] The hole opener switch is electrically connected to the first hole opener and the second hole opener, and the forward and reverse switch is electrically connected to the driving motor.

[0011] Furthermore, one end of the second connecting rod is hinged to the second nut, and the other end of the second connecting rod is hinged to the second fixing seat.

[0012] Furthermore, one end of the fourth connecting rod is hinged to the second nut, and the other end of the fourth connecting rod is hinged to the first fixing seat.

[0013] Furthermore, the thread on the first driving screw is opposite to the thread on the second driving screw.

[0014] Furthermore, the first connecting rod and the third connecting rod are symmetrically arranged with respect to the first driving screw.

[0015] Furthermore, the second connecting rod and the fourth connecting rod are symmetrically arranged with respect to the first driving screw.

[0016] Furthermore, the first hole opener and the second hole opener are on the same horizontal line.

[0017] Furthermore, the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod are in the same plane, and this plane is parallel to the telescopic support.

[0018] Furthermore, the bottom of the telescopic support is provided with rollers, and the hole opener switch and the forward and reverse switch are located on both sides of the telescopic support.

The forward rotation of the first driving screw and the second driving screw makes the first nut and the second nut approach each other. Driven by the first connecting rod, the second connecting rod, the fourth connecting rod, and the third connecting rod, the drill bits of the first hole opener and the second hole opener are pressed against the beam formwork, and then the forward and reverse switch is turned off.

[0020] Then start the hole opener switch, control the first hole opener and the second hole opener to perform the hole opening work, and start the forward and reverse switch to make the first hole opener and the second hole opener extend to both sides to start hole opening. After penetrating the beam formwork, control the forward and reverse switch again to make the first hole opener and the second hole opener retract in the reverse direction, and the drilling is completed. Then push the bracket to perform the next drilling operation.

[0021] When drilling the high beam formwork, the construction workers only need to control the drilling device through the hole opener switch and the forward and reverse switch on the working platform to adjust the drilling distance and drill holes. The telescopic bracket is used to ensure the drilling requirements at different elevations. The driving motor drives the first driving screw rod and the second driving screw rod to rotate simultaneously, so that the moving distances of the first hole opener and the second hole opener are the same, and the two sides of the beam formwork can be drilled simultaneously to ensure the drilling requirements for different widths. The bottom of the telescopic bracket is provided with rollers. After the drilling is completed, push the bracket to perform the next drilling operation, which saves time and effort, is convenient to operate, and has a wide range of applications.
