Description

Technical Field

[0001] This utility model relates to the field of rebar drilling technology, and in particular to a secondary structure rebar drilling device. Background Technology

[0002] Rebar anchoring is a connection technology in seismic reinforcement of building structures that uses structural adhesive to lock and hold the rebar in place. It is the best choice for structural rebar anchoring reinforcement and heavy load fastening applications.

[0003] In engineering construction, secondary structure rebar installation often involves drilling at heights. Traditionally, drilling holes at the bottom of beams is done manually by setting up ladders and using handheld electric drills. This method requires scaffolding to ensure the safety of workers, which is labor-intensive and inefficient. Furthermore, when workers are in high-rise environments, there are drawbacks such as poor verticality of holes drilled with handheld electric drills at heights, and low safety. Utility Model Content

[0036] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Please see Figures 1 to 6 The secondary structure rebar drilling device of this utility model includes a storage frame 100, a support cylinder 110 is movably inserted into the storage frame 100, the top of the support cylinder 110 is connected to a first connecting cylinder 120 and a second connecting cylinder 130 by means of threads, and the top of the second connecting cylinder 130 is equipped with a drilling assembly 140 for drilling holes at the bottom of indoor beams.

[0038] The ends of the first connecting cylinder 120 and the second connecting cylinder 130 are connected by threads. The first connecting cylinder 120 and the second connecting cylinder 130 are fitted with threaded first inner rods 121 and 131. The support cylinder 110 is equipped with an electric push rod 150 that drives the first inner rods 121 and 131 to rise. The outer wall of the first connecting cylinder 120 is movably fitted with a positioning ring 125 that limits the height of the first inner rod 121. The storage frame 100 has reserved space for storing the support cylinder 110, the first connecting cylinder 120 and the second connecting cylinder 130.

[0039] The storage frame 100 has L-shaped panels 105 at both ends that slide within the storage frame 100. Each set of L-shaped panels 105 has an arc-shaped block 107 fixed to its front and back. The bottom of the storage frame 100 has a drawer 101 that slides with a dovetail. The front and back inner walls of the drawer 101 have horizontal grooves 103 for the arc-shaped blocks 107 to slide. An elastic element 104 that constrains the arc-shaped blocks 107 is fixed in the horizontal grooves 103.

[0040] The back surface of drawer 101 has a notch 102 for extending wires out of the outside of drawer 101. The lower inner wall of storage frame 100 is fixed with a positioning bracket 108 in the center. The upper surface of positioning bracket 108 has a blind hole 109 for inserting the bottom of support cylinder 110.

[0041] The curved outer wall of the support cylinder 110 is stacked and has two sets of storage slots 111. Each set of storage slots 111 has a rotatable support arm 113. The top of the L panel 105 has a damping shaft with a limiting support 106 sleeved at the end of the support arm 113. The bottom of the support cylinder 110 is threadedly connected to the end cap 112 of the electric push rod 150.

[0042] The first inner rod 121 is slidably disposed inside the first connecting cylinder 120. Two sets of first constraint blocks 122 are fixed symmetrically on the curved outer wall of the first inner rod 121. The inner wall of the first connecting cylinder 120 is provided with a first constraint groove 128 that is adapted to the first constraint block 122, and the first constraint groove 128 extends to the bottom end of the first connecting cylinder 120.

[0043] The outer wall of the first connecting cylinder 120 is provided with a travel groove 124 that communicates with two sets of first constraint grooves 128. The two sets of travel grooves 124 are slidably provided with a stop block 129 that is fixed to the inner wall of the positioning ring 125. The two sets of stop blocks 129 are located above the first constraint block 122. The outer wall of the positioning ring 125 is fixed with two sets of locking bolts 126 that abut against the outer wall of the first connecting cylinder 120. The outer wall of the first connecting cylinder 120 is provided with a long straight groove 127 at the position where it contacts the end of each set of locking bolts 126.

[0044] Two sets of second constraint blocks 132 are fixed on the outer wall of the second connecting cylinder 130. A second constraint groove 134 is provided at the position where the inner wall of the second connecting cylinder 130 contacts the two sets of second constraint blocks 132, and the second constraint groove 134 extends to the top of the second connecting cylinder 130. The upper and lower ends of the second inner rod 131 are provided with threaded portions 133. The top of the first inner rod 121 is provided with a threaded hole 123 that matches the threaded portion 133.

[0045] The outer wall of the first connecting cylinder 120 is engraved with a scale.

[0046] like Figure 1 As shown, the two sets of support arms 113, which unfold into a figure-eight shape, prevent the support cylinder 110 from tipping over. The limiting bracket 106 restricts the unfolding angle of the two sets of support arms 113, preventing the support arms 113 from continuing to unfold outward. At the same time, the bottom of the support cylinder 110 is inserted into the blind hole 109, further improving the stability of the support cylinder 110, so that the drilling equipment above is in a stable and vertical state for drilling.

[0047] Before drilling into the bottom of the beam indoors, refer to the scale on the outer wall of the first connecting cylinder 120. Push the positioning ring 125 to slide on the outer wall of the first connecting cylinder 120 and determine the position of the positioning ring 125 by referring to the scale. At this time, rotate the locking bolt 126 to abut against the long straight groove 127, thereby fixing the positioning ring 125 to the outer wall of the first connecting cylinder 120. At this time, the stop block 129 is directly above the first constraint block 122. The extension end of the electric push rod 150 can be controlled to rise, which will lift the first inner rod 121 upward inside the first connecting cylinder 120. Since the first inner rod 121 is threadedly connected to the second inner rod 131, the second inner rod 131 will also rise upward in the second connecting cylinder 130, lifting the drilling assembly 140 to rise and drill into the bottom of the beam. The top of the first constraint block 122 will contact the stop block 129, preventing the first inner rod 121 and the second inner rod 131 from rising further. This indicates that the drilling depth at the bottom of the beam meets the construction requirements. It is worth noting that the electric push rod 150 is started and stopped by an external remote control. The top of the electric push rod 150 is equipped with a pressure sensor. When the pressure collected by the pressure sensor exceeds the preset threshold, the electric push rod 150 stops rising.

[0048] After drilling the bottom of the beam, the second connecting cylinder 130 and the first connecting cylinder 120 can be rotated one by one to separate them and place them into the storage frame 100. The first inner rod 121 and the second inner rod 131 remain in the first connecting cylinder 120 and the second connecting cylinder 130, respectively. At this time, the upper body of the support cylinder 110 is removed from the blind hole 109, the support arm 113 of the train is rotated and enters the storage groove 111, and then placed into the storage frame 100. The L-panels 105 at both ends are pushed towards the center and sealed to block the storage. At the top of the frame 100, the arc-shaped block 107 compresses the elastic element 104 to deform, and as the L panel 105 moves, it passes by the side of the elastic element 104. The elastic element 104 returns to its original state to prevent it from sliding left and right, so that the L panel 105 is stably placed on the top of the storage frame 100. At the same time, the wires connected to the drilling assembly 140 and the electric push rod 150 can be put into the drawer 101, and the drilling assembly 140 is stored in other boxes. This reduces the space occupied by the device and makes it convenient for manual carrying or handling.

[0049] Please refer to this carefully. Figure 1 and Figure 3 The drilling assembly 140 includes a support plate 141 threadedly connected to the top of the second inner rod 131. A drilling machine 144 for drilling holes in the bottom of the beam is mounted on the top of the support plate 141. A rectangular frame 142 fixed to the top of the support plate 141 is provided on the outer wall of the drilling machine 144.

[0050] Two sets of clamping plates 145 are slidably provided inside the support plate 141 to abut against the outer wall of the drilling machine 144. The outer wall of the support plate 141 is threadedly connected to a threaded shank 143 that drives the clamping plates 145 to clamp the drilling machine 144. A matching threaded channel is provided at the contact position between the outer wall of the support plate 141 and the threaded shank 143.

[0051] The output end of the drilling machine 144 rotates, causing the drilling cutter at its end to drill holes in the bottom of the beam. The drilling cutter at its output end can be flexibly disassembled and replaced, and the replacement method is achieved using existing technology.

[0052] Before drilling, the two sets of threaded shanks 143 need to be manually rotated to bring the clamping plate 145 closer to the drilling machine 144 until the clamping is completed, so that the drilling machine can stably drill holes at the bottom of the beam.

[0053] Please refer to this carefully. Figure 1 and Figure 4 The blind hole 109 has slots on both sides for storing the support cylinder 110, the first connecting cylinder 120, and the second connecting cylinder 130. The support cylinder 110, the first connecting cylinder 120, and the second connecting cylinder 130 are smaller than the length of the storage frame 100, so that the split support cylinder 110, the first connecting cylinder 120, and the second connecting cylinder 130 can be placed side by side into the slots, which can reduce the overall space occupied by them and make it easier for manual carrying or handling.

[0054] The secondary structure rebar drilling device may also include a battery installed in the storage frame 100. The battery is electrically connected to the power supply components, such as the drilling assembly 140 and the electric push rod 150, so that the device can be continuously powered anytime and anywhere.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
