Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and relates to a rapid rebar installation scheme at the junction of a ring-braced beam and an existing structural beam. More specifically, it relates to a rapid rebar installation device and method in a confined space. Background Technology

[0002] In existing building renovation or reinforcement projects, the installation of rebar at the junction of the circumferential bracing beam and the existing structural beam faces the following challenges:

[0003] 1) Narrow operating space: Traditional rebar installation requires steps such as drilling, gluing, and inserting rebar. However, the space at the junction of the ring beam and the existing structural beam is very small. Construction workers cannot install rebar in the confined space, making it difficult to exert force on the drilling machine. This makes it difficult to adjust the drilling machine angle in the narrow space, and incomplete hole cleaning leads to insufficient adhesive bonding strength.

[0004] 2) Low construction efficiency: Manual operation is time-consuming and labor-intensive, and is prone to quality problems due to space limitations.

[0005] In existing technologies, rebar installation relies on manual experience and lacks specialized tools, resulting in insufficient flexibility.

[0006] Therefore, there is an urgent need for a rapid rebar installation device and its usage method in confined spaces where workers can quickly and effortlessly install rebar at the junction of the ring-braced beam and the existing structural beam without having to climb scaffolding or ladders. This device would improve the efficiency of rebar installation, effectively ensure the quality of drilling, and reduce safety hazards during construction. Summary of the Invention

[0007] In view of the above problems, the purpose of this invention is to provide a rapid rebar installation device and method in a confined space to solve the technical problem in the prior art that when installing rebar at the junction of a ring brace beam and an existing structural beam, it is difficult to drill holes to the left and right in a confined working space, making it impossible for construction personnel to work in the confined space.

[0008] This invention provides a rapid rebar installation device for confined spaces, comprising a mobile vehicle, a frame, and an electric drill mounted on the frame; wherein,

[0009] A back panel is provided on the mobile vehicle body;

[0010] A transmission mechanism is provided on the back plate;

[0011] The transmission mechanism is connected to the frame and can drive the frame to move the electric drill up and down.

[0013] Preferably, the transmission mechanism further includes a small gear fixed to the back plate; wherein,

[0014] The small gear meshes with the large gear. Rotating the small gear can drive the large gear to rotate, and the large gear drives the rack to move up or down.

[0015] Preferably, the frame includes poles and supports; wherein,

[0016] The top of the rod and the rack are fixedly connected by a socket joint;

[0017] The support body is arranged perpendicularly to the rod body, and a bracket is provided on the support body for supporting and fixing the electric drill.

[0018] Preferably, a spring is provided at the bottom of the rack;

[0019] The bottom end of the spring is fixed to the moving vehicle body.

[0020] Preferably, a turntable is provided on the rod body, the turntable is mechanically connected to the pinion, and the pinion can be driven to rotate by rotating the turntable.

[0021] Preferably, the rod body includes a fixed rod body and a rotatable rod body disposed above the fixed rod body, the rotatable rod body being connected to the fixed rod body via a fastener; the turntable is fixed to the bottom of the rotatable rod body; wherein,

[0022] When the fixing fastener is opened, the turntable can be used as a handle. By rotating the turntable horizontally, the rotatable rod body can be rotated, thereby driving the electric drill to move left and right.

[0023] When the fixing fastener is closed, the rotatable rod is secured above the fixing rod.

[0024] Preferably, a fixing screw is provided at the bottom of the mobile vehicle body.

[0025] Preferably, the back plate is fixed to the mobile vehicle body by back plate support.

[0026] This invention also provides a method for rapid rebar installation in confined spaces, using the rapid rebar installation device for confined spaces as described above to rapidly install rebar at the junction of a ring brace beam and an existing structural beam. The method includes:

[0027] Push the mobile vehicle body to the junction of the ring support beam and the existing structural beam, so that the frame above the mobile vehicle body and the electric drill set on the frame are below the junction of the ring support beam and the existing structural beam.

[0028] The transmission mechanism on the control back plate enables the frame to drive the electric drill to move up and down for rapid rebar installation; wherein, the back plate is mounted on the mobile vehicle body.

[0029] As can be seen from the above technical solution, the rapid rebar installation device and method in confined spaces provided by the present invention, by setting a frame and back plate above the mobile vehicle body, and setting a transmission mechanism on the back plate, allows the electric drill to be placed above the frame. The transmission mechanism controls the up-and-down movement of the electric drill, and the left-and-right movement can be controlled by rotating the frame. Thus, in the confined space at the intersection of the ring beam and the existing structural beam, the turntable can be adjusted to change the direction of the drill, meeting the requirements for drilling and rebar installation in all 360 degrees. This solves the problems of difficulty in drilling left and right holes in a limited working space and the inability of construction personnel to work in confined spaces when installing rebar at the intersection of the ring beam and the existing structural beam. By changing the operating method through the device, it achieves both labor-saving and rapid rebar installation of structural beams, effectively improving the efficiency of rebar installation work, while effectively ensuring the quality of drilling and reducing safety hazards during construction.

[0034] During the rebar installation process at the junction of the ring beam and the existing structural beam, the narrow operating space usually prevents the construction personnel from installing the rebar in the confined space, making it difficult for the drilling rig to exert force. The narrow space makes it difficult to adjust the drilling rig angle, and incomplete hole cleaning leads to insufficient adhesive bonding strength, resulting in poor construction effect and low construction efficiency.

[0035] To address the aforementioned problems, this invention provides a rapid rebar installation device and method for confined spaces. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0036] To illustrate the rapid rebar installation device and method for confined spaces provided by this invention Figure 1 , Figure 2 The embodiments of the present invention are illustrated by way of example.

[0037] The following description of exemplary embodiments is merely illustrative and is in no way intended to limit the invention or its application or use. Techniques and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques and equipment should be considered part of the specification.

[0038] like Figure 1 As shown, this embodiment of the invention provides a rapid rebar installation device in a confined space, including a mobile vehicle body 7, a frame, and an electric drill 10 mounted on the frame; wherein, a back plate 1 is provided on the mobile vehicle body 7; a transmission mechanism is provided on the back plate 1, which is connected to the frame and can drive the frame to move the electric drill up and down.

[0039] In this embodiment, the transmission mechanism includes a small gear 3 and a large gear 2 fixed on the back plate 1, and a rack 5 that can be meshed and driven by the large gear 2. The small gear meshes with the large gear, and rotating the small gear can drive the large gear to rotate. The large gear drives the rack to move up or down, so that the upward or downward movement of the rack can be controlled by rotating the small gear.

[0040] In this embodiment, the frame includes a pole (vertical part) and a support 9 (horizontal part); the top of the pole and the rack 5 are fixedly connected by a socket joint 8; the support 9 is arranged perpendicularly to the pole, and a bracket is provided on the support 9 for supporting and fixing the electric drill. The pole can be made of a slightly thicker steel pipe, and the support 9 can be made of short, thin steel pipes fixed side by side and welded to the thicker steel pipe (pole). In this embodiment, two electric drills are provided to improve the overall efficiency of rebar installation.

[0041] In this embodiment, a spring 4 is provided at the bottom of the rack 5. The bottom end of the spring 4 is fixed to the moving vehicle body 7. In this embodiment, the moving vehicle body 7 is a pallet truck. The spring 4 is set on the pallet plane of the pallet truck, so that the spring plays a role in buffering and assisting, reducing the resistance of the pinion when controlling the rack to rise through the large gear, and providing buffering for the rack to descend.

[0042] In this embodiment, the worker rotates the small gear by turning the turntable 12. That is, a turntable is set on the rod body. The turntable 12 is mechanically connected to the small gear. By rotating the turntable, the small gear can be driven to rotate, thereby driving the large gear to rotate. The large gear drives the rack to move up and down, thereby driving the frame to move up and down. This can drive the electric drill to move up and down, thus facilitating the rebar installation.

[0043] In one specific embodiment, wheels are provided at the bottom of the mobile vehicle body, and omnidirectional wheels can be provided, so that the position and direction of the electric drill in the horizontal direction can be adjusted by pushing the mobile vehicle body.

[0044] To more conveniently control the position and direction of the electric drill in a horizontal state, in another specific embodiment, the rod body includes a fixed rod body (the part below the fixing fastener 14 in the figure) and a rotatable rod body disposed above the fixed rod body (the part above the fixing fastener 14 in the figure). The rotatable rod body is connected to the fixed rod body through the fixing fastener 14. A turntable is fixed to the bottom of the rotatable rod body. When the fixing fastener 14 is opened, the turntable can be used as a handle. By rotating the turntable horizontally, the rotatable rod body is rotated, thereby driving the electric drill to move left and right, thus enabling the electric drill to be controlled at various angles (360 degrees) in the horizontal direction. When the fixing fastener 14 is closed, the rotatable rod body is fastened above the fixed rod body to facilitate stable control of the electric drill's up and down movement.

[0045] Correspondingly, in this specific embodiment, a fixing screw is provided at the bottom of the mobile vehicle body to securely fix the mobile vehicle body below the junction of the ring support beam and the existing structural beam, so as to provide stable support for the components above.

[0046] Furthermore, in this embodiment, the back plate 1 is fixed to the mobile vehicle body 7 by the back plate support 6, thereby firmly fixing the back plate to the mobile vehicle body such as the trailer, so as to provide stable support for the transmission mechanism.

[0047] When installing the rapid rebar installation device in the confined space in this embodiment, the gear set can be installed first. The large gear 2, small gear 3, and rack 5 are installed according to the design position. After installation, the gears are rotated for adjustment, and the position of rack 5 is adjusted to install spring 4. Then, the electric drill 10 and the support body 9 are installed. The electric drill 10 is fixed on the bracket 11 of the support body 9 so that the electric drill 10 is along the steel pipe direction of the support body 9 and is firmly secured.

[0048] Install the turntable 12 with the small gear 3, place the back plate 1 upright on the pallet cart, fix the back plate support 6, rotate the turntable 12 to tighten the spring device 4, install the steel pipe frame on the socket joint 8, and push the pallet cart to the position where drilling is required to prepare for drilling.

[0049] When using the rapid rebar installation device in the confined space of this embodiment, align the drill 10 with the location where the structural beam needs to be drilled, turn on the electric drill 10 switch, and rotate the turntable 12 to move the electric drill 10 upward to drill, achieving efficient and rapid drilling. Compared with the traditional rebar installation method, it liberates human labor, improves drilling efficiency and worker enthusiasm, thereby ensuring the construction quality of drilling, and enabling the rebar installation work at the junction of the ring brace beam and the existing structural beam to be completed quickly and with high quality.

[0050] As described above, the rapid rebar installation device in confined spaces provided by the present invention can ensure the construction quality of drilling at low cost, enabling the rebar installation work at the junction of the ring brace beam and the existing structural beam to be completed quickly and with high quality, thereby improving the overall rebar installation efficiency and quality.

[0051] like Figure 2 As shown, the present invention also provides a method for rapid rebar installation in confined spaces, using the rapid rebar installation device for confined spaces as described above, the method comprising:

[0052] S1: Push the mobile vehicle body to the junction of the ring support beam and the existing structural beam, so that the frame above the mobile vehicle body and the electric drill set on the frame are below the junction of the ring support beam and the existing structural beam.

[0053] S2: Control the transmission mechanism on the back plate to enable the frame to drive the electric drill to move up and down for rapid rebar installation; wherein, the back plate is set on the moving vehicle body.
