Description

Technical Field

[0001] This utility model relates to the technical field of steel structure construction equipment, and more specifically, to a magnetic drill trolley. Background Technology

[0002] In the fabrication of steel bridge structures, to ensure efficient and rapid on-site installation, pre-assembly is often required at the manufacturing plant to guarantee the installation accuracy at bridge segment connections and the bolt perforation rate. Using standard connecting plates for multi-segment drilling can avoid the need for pre-assembly reaming and enlarging. However, due to the large cross-sections of the components, conventional drilling methods cannot be used in the factory. In particular, the dense and numerous holes in the inclined T-shaped webs of bridges often require multiple workers to lift the magnetic drill to a suitable position and then magnetically attach it to the web for drilling. This involves high labor intensity for workers, and after drilling is completed, the magnetic drill loses its magnetism, which can easily cause it to fall and injure the equipment or even workers. Utility Model Content

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-9 As shown in the figure, the magnetic drill trolley proposed in this embodiment can be used to assist the magnetic drill in drilling holes on the web of vertical or inclined T-shaped steel beams, and can also be used to assist the magnetic drill in drilling holes on other vertical T-shaped steel structures.

[0027] This magnetic drill trolley includes a traveling carriage 1 and a fall arrestor 2 connected to the traveling carriage 1. The traveling carriage 1 is used to move on the upper flange 3 of the T-shaped steel beam. The traveling carriage 1 is connected to the magnetic drill 5 through the fall arrestor 2, so that the magnetic drill 5 is always suspended on the traveling carriage 1 and will not fall to the ground.

[0028] To facilitate the movement of the traveling vehicle 1 on the upper wing plate 3, the traveling vehicle 1 may include a frame 11. A first bracket 12 and a second bracket 13 are connected to the lower part of the frame 11. Support wheel assemblies 14 are provided on both the first bracket 12 and the second bracket 13. A traveling wheel assembly 15 is provided at the lower part of the frame 11 between the first bracket 12 and the second bracket 13. The support wheel assembly 14 and the traveling wheel assembly 15 respectively contact the lower and upper sides of the upper wing plate 3 of the web plate 4 to be drilled, and slide along the length direction of the upper wing plate 3.

[0029] The frame 11 is positioned above the upper wing plate 3 and supports the wheels and fall arrestor 2 that travel on the upper wing plate 3. For stable movement, a set of traveling wheels 15 that moves along the upper side of the upper wing plate 3 is provided at the lower part of the frame 11, while a set of support wheels 14 that moves along the lower side of the upper wing plate 3 is provided at the lower part of the frame 11. The traveling wheel set 15 and the support wheel set 14 hold the upper wing plate 3 in the middle and roll along the upper and lower sides of the upper wing plate 3, ensuring stable movement and preventing the frame 11 from tilting or shifting.

[0030] The support wheel assembly 14 is respectively mounted on the first bracket 12 and the second bracket 13 connected to the frame 11, ensuring a stable and secure installation. The upper wing plate 3 has a traveling wheel assembly 15 above it, a support wheel assembly 14 below it, and the first bracket 12 and the second bracket 13 on the left and right sides, enclosing the upper wing plate 3. This allows the frame 11 to move stably on the upper wing plate 3 without shifting or falling off due to the hanging force of the magnetic drill 5. When the horizontal position of the magnetic drill 5 on the vertical web plate 4 changes, the traveling carriage 1 can move accordingly, easily and flexibly following the magnetic drill 5.

[0031] To flexibly connect the magnetic drill 5 at different heights, one end of the fall arrestor 2 is connected to the frame 11, and the other end is connected to the handle of the magnetic drill 5. When the vertical position of the magnetic drill 5 on the vertical web plate 4 changes, the fall arrestor 2 can be raised or lowered accordingly, and its length is adapted to the connection with the magnetic drill 5.

[0032] Since the magnetic drill 5 is connected to the frame 11 through the fall arrestor 2, when the magnetic drill 5 loses its magnetism, the magnetic drill 5 can be moved by lifting the fall arrestor 2, thus reducing the lifting force on personnel.

[0033] In one specific embodiment of this utility model, for the stability of the frame 11, the frame 11 includes a rectangular upper plate 111, the length of which is greater than the width of the upper wing plate 3 and is perpendicular to the upper wing plate 3. End plates 112 are vertically connected to both ends of the upper plate 111, and a lower plate 113 is connected between the lower ends of the two end plates 112. The upper plate 111 and the lower plate 113 form an H-shaped frame 11. The two end plates 112 enhance the stability of the frame, and the frame 11 spans across the upper wing plate 3.

[0034] To facilitate the installation of wheels, the lower plate 113 includes a middle plate 114 of the same size as the upper plate 111 and two side plates 115 disposed on both sides of the middle plate 114. The side plates 115 are on the same plane as the middle plate 114 and their length is not less than the width of the upper wing plate 3. The length of the side plates 115 can be about two-thirds of the length of the middle plate 114, one end of the side plates 115 is close to one end of the middle plate 114, and the width of the side plates 115 is sufficient for the installation of wheels.

[0035] To further enhance the robustness of the frame 11, a reinforcing plate 116 is connected between the center lines of the upper plate 111 and the lower plate 113, with both ends of the reinforcing plate 116 connected to two end plates 112 respectively. The reinforcing plate 116 can firmly support the upper plate 111 and the lower plate 113, enabling the frame 11 to withstand the pulling force of the magnetic drill 5.

[0036] In one specific embodiment of this utility model, for stable and balanced movement of the traveling wheels, the traveling wheel assembly 15 includes traveling wheels 151 respectively arranged at both ends of the side plate 115 with a spacing smaller than the width of the upper wing plate 3. The middle surface of the two traveling wheels 151 on the side plate 115 can be on the same vertical plane as the middle surface of the two support wheel assemblies 14. After the frame 11 is installed on the upper wing plate 3, the two traveling wheels 151 on each side plate 115 can be symmetrical about the center line of the upper wing plate 3. A total of four traveling wheels roll on the upper wing plate 3, and the two sets of support wheel assemblies 14 roll on the lower side of the upper wing plate 3, so that the frame 11 moves in a balanced and stable manner.

[0037] In one specific embodiment of this utility model, in order to reduce the vibration of the frame 11 when it moves on the upper wing plate 3, the running wheel 151 is connected to the side plate 115 through a compression spring assembly 152. The shock absorption of the compression spring assembly 152 can extend the service life of the frame 11 and prevent damage to the upper wing plate 3.

[0038] In one specific embodiment of this utility model, the compression spring assembly 152 may include four fully threaded bolts 1521 passing through the side plate 115, and four sets of fully threaded bolt holes are provided at corresponding positions on the side plate 115. After the fully threaded bolts 1521 pass through the fully threaded bolt holes, they are fixedly connected to the side plate 115 by fastening nuts 1522 screwed onto both sides of the side plate. A straight rod 1523 is connected to the lower end of the fully threaded bolts 1521, and a spring 1524 is sleeved on the straight rod 1523. The lower ends of the two straight rods 1523 pass through two round holes on the moving plate 1525 and are screwed with limit nuts 1526. The springs 1524 on the straight rods 1523 act as shock-absorbing springs. The two ends of the springs 1524 abut against the fastening nuts 1522 and the moving plate 1525, respectively. The up and down movement of the moving plate 1525 can compress and release the springs 1524, and the limit nuts 1526 can prevent the moving plate 1525 from disengaging from the straight rods 1523.

[0039] The traveling wheel 151 is installed below the movable plate 1525 to provide cushioning. Two fixed plates 153 can be provided in the middle of the lower part of the movable plate 1525, and the two ends of the axle of the traveling wheel 151 are rotatably connected to the two fixed plates 153 respectively. The traveling wheel 151 rotates smoothly between the two fixed plates 153 and is smoothly damped by the four springs 1524 on the upper part.

[0040] Adjusting the position of the threaded bolt 1521 within the hole allows for adjustment of the distance between the traveling wheel 151 and the frame 11, enabling the traveling wheel 151 and support wheel assembly 14 to accommodate upper wing plates of varying thicknesses. The outer diameter of the fastening nut 1522 should be larger than the outer diameter of the spring 1524. The diameter of the circular hole on the moving plate 1525 should match the outer diameter of the straight rod 1523, and the area of ​​the moving plate 1525 should be sufficient to stably compress the spring 1524.

[0041] In a specific embodiment of this utility model, in order to stably install the support wheel assembly 14, the first bracket 12 includes a first connecting plate 121, a mounting plate 122 and a first support plate 123 respectively vertically connected to both ends of the first connecting plate 121, and the mounting plate 122 and the first support plate 123 have opposite orientations, forming a Z-shaped bracket. To stably install the first bracket 12, four through holes 124 are provided on the mounting plate 122, and four elongated holes 117 corresponding to the four through holes 124 are provided on the middle plate 114. The mounting plate 122 and the middle plate 114 are connected by bolts and nuts provided on the corresponding through holes 124 and elongated holes 117, allowing for flexible fine-tuning of the position of the first bracket 12, so that the distance between the first bracket 12 and the second bracket 13 adapts to different upper wing plate widths. The first bracket 12 and the second bracket 13 can both be close to the edge of the upper wing plate 3, preventing the frame 11 from shifting.

[0042] The second bracket 13 may include a vertically connected second connecting plate 131 and a second support plate 132, forming an L-shaped bracket. The upper end of the second connecting plate 131 is welded to the lower side of the middle plate 114. The second support plate 132 and the first support plate 123 are on the same plane, and the distance between them is less than the width of the upper wing plate 3. The support wheel assembly 14 on the second support plate 132 and the first support plate 123 can provide balanced support under the upper wing plate 3.

[0043] In one specific embodiment of this utility model, the support wheel assembly 14 may include two bearing wheels 141. The two bearing wheels 141 can increase the rolling area on the lower side of the upper wing plate 3, making the movement smoother. The two bearing wheels 141 can be arranged along the length direction of the upper wing plate 3.

[0044] In one specific embodiment of this utility model, two wheel plates 142 are provided on both the first support plate 123 and the second support plate 132, and the two ends of the axle of the bearing wheel 141 are respectively rotatably connected to the two wheel plates 142. The wheel plates 142 can stably support the bearing wheel 141 and enable the bearing wheel 141 to rotate smoothly.

[0045] In one specific embodiment of this utility model, for connecting the fall arrester, an ear plate 21 is connected to the end of the middle plate 114 away from the side plate 115, and the fall arrester is connected to the ear plate 21. The fall arrester can be replaced by a hand chain hoist 22. The upper end of the hand chain hoist 22 is connected to the ear plate 21, and the lower end is connected to the handle of the magnetic drill 5. By pressing the button on the hand chain hoist 22, the connection length with the magnetic drill 5 can be easily adjusted, facilitating the hoisting of the magnetic drill 5 to a suitable height.

[0046] When installing the frame 11, the first bracket 12 can be separated from the frame 11. First, the second bracket 13 is installed with the upper wing plate 3, and then the first bracket 12 is installed. The support wheel assembly 14 is attached to the lower side of the upper wing plate 3. The tightening position of the fastening nut 1522 on the fully threaded bolt 1521 is adjusted according to the distance between the upper side of the upper wing plate 3 and the bottom surface of the frame 11, so that the running wheel assembly 15 contacts the upper side of the upper wing plate 3, and the elasticity of the compression spring assembly 152 is moderate.
