Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for safety warnings in road and bridge construction, specifically to a combined nail remover for windproof nails. Background Technology

[0002] When arranging box girders on bridge piers, safety warning devices need to be installed under the bridge to remind personnel to be vigilant near the piers in the work area. Currently, safety cones made of rubber are often used in the field in conjunction with windproof nails, which nail the base of the cones to the ground. As the project progresses, the piers where cones need to be placed will gradually move forward. However, since the cones are already nailed to the windproof nails, it is difficult to move them, which is the main problem we are currently facing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a combined nail remover for windproof nails, so as to solve the current problem that it is difficult to remove windproof nails from safety cones that have been nailed to the ground, and that the safety cones are difficult to reuse.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A combined nail remover for windproof nails includes a safety cone nailed to the ground; a flat pad is provided on the ground near the safety cone; a support block is provided on the flat pad; a lever is rotatably mounted on the top of the support block; a connector is provided on the lever; a pressure-bearing clamp is provided at the connector; a limit groove is formed on the pressure-bearing clamp; the head of the windproof nail can be engaged with the pressure-bearing clamp through the limit groove.

[0006] The support block is a steel pipe that is vertically installed in the middle of the flat pad; there are through holes on the top of the support block and on one end of the lever, and the two are hinged together at the through holes.

[0007] The lever is a straight rod with a pair of clamps installed on one end. The two clamps are clamped to the top two of the support block. Through holes are opened in the clamps. The lever is hinged to the support block through the clamps. When the lever rotates relative to the support block, the two do not interfere with each other.

[0008] The connector is located in the middle of the lever near the support block; a non-slip grip is provided at the other end of the lever.

[0009] The lever has a positioning hole; the connector includes a bolt that passes through the positioning hole from top to bottom; a sleeve is detachably provided on the underside of the bolt via a threaded connection; and a pressure-bearing clamp is installed on the outer wall of the sleeve.

[0010] A washer is placed between the nut on the top side of the bolt and the lever; the lever is made of wood or steel.

[0011] The pressure-bearing clamp is an L-shaped angle steel; the limiting groove is located in the middle of the lower side plate of the pressure-bearing clamp; reinforcing guard plates are provided on the left and right sides of the pressure-bearing clamp. Preferably,

[0012] The beneficial effects of this utility model are reflected in the following aspects:

[0013] 1. This utility model, through the lever principle combined with the structural features of the pressure-bearing clip, can quickly and effortlessly pull out the windproof nails that are deeply embedded in the ground, completely solving the core problem that safety triangular cones are difficult to move and circulate due to being fixed by windproof nails, and significantly improving construction efficiency;

[0014] 2. Using the support block as a fulcrum, the operator only needs to apply a small downward pressure at the end of the lever to generate a strong vertical upward lifting force at the pressure-bearing clamp head through the amplification effect of the lever, easily overcoming the friction between the windproof nail and the ground. It can be operated by a single person, greatly reducing labor intensity. The limiting groove set on the pressure-bearing clamp head can accurately engage the head of the windproof nail, providing a stable gripping force during the lever lifting process and effectively preventing the nail head from slipping off during nail removal.

[0015] 3. The structure is robust and reliable, using steel pipes as support blocks, wooden or steel levers, L-shaped angle steel pressure clamps, and reinforced guard plates. The flat pads increase the contact area with the ground, disperse the pressure at the fulcrum, prevent the support blocks from sinking into soft ground, and ensure the stability of the device during operation. The clamp-type hinge design ensures smooth lever rotation and a firm connection.

[0016] 4. The design of the connecting parts consisting of bolts and sleeves allows the height of the pressure-bearing clamp to be adjusted according to the height of the windproof nail protruding from the ground, enhancing adaptability; the bolt connection also facilitates the replacement or maintenance of the pressure-bearing clamp or sleeve.

[0017] 5. The main components can be relatively separated or easily disassembled, facilitating rapid assembly and use at different bridge pier work sites; the device has a clear structure and simple operation steps; the anti-slip grip design improves the operator's grip comfort and safety, preventing slippage when applying force; it avoids the risk of tool damage or personal injury that may be caused by using tools such as hammers and crowbars.

[0018] 6. By easily removing the windproof nails, the safety cones can be quickly retrieved and re-deployed to new pier locations, greatly improving the efficiency and turnover rate of the safety warning equipment and reducing equipment configuration costs. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] Example:

[0024] Reference Figure 1 This embodiment provides a combined nail remover for windproof nails. It includes a safety cone 2 nailed to the ground by a windproof nail 1; a flat pad 3 is placed on the ground near the safety cone 2; the flat pad 3 is typically a steel plate with a certain thickness and area; its function is to distribute the fulcrum pressure, prevent the device from sinking in soft ground (such as soil or gravel), and ensure a stable foundation for the entire nail removal process; a support block 4 is placed on the flat pad 3; a lever 5 is rotatably mounted on the top of the support block 4; a connector 6 is placed on the lever 5; a pressure-bearing clamp 7 is placed at the connector 6; a limiting groove 71 is formed on the pressure-bearing clamp 7; the head of the windproof nail 1 can be clamped onto the pressure-bearing clamp 7 through the limiting groove 71. In this embodiment, the limiting groove 71 is a strip-shaped groove structure.

[0025] The support block 4 is a steel pipe that is vertically installed in the middle of the flat pad 3. The inside of the steel pipe can be hollow or filled with counterweights such as concrete or sand as needed to increase the overall stability of the device, especially to prevent the support block from overturning when the lever applies a large downward pressure. There are through holes on the top of the support block 4 and on one end of the lever 5, and the two are hinged at the through holes.

[0026] Lever 5 is a straight rod with a pair of clamping plates 8 mounted on one end. The two clamping plates 8 are clamped to the top two of the support block 4. Through holes are formed in the clamping plates 8. Lever 5 is hinged to the support block 4 via the clamping plates 8. When lever 5 rotates relative to the support block 4, the two do not interfere with each other. The design of the clamping plates 8 allows lever 5 to rotate at a large angle in the vertical plane, thus providing sufficient stroke to completely pull out windproof nails of different embedment depths.

[0027] Connector 6 is located in the middle of lever 5 near support block 4; a non-slip grip 9 is provided at the other end of lever 5. The non-slip grip 9 is usually made of rubber, silicone or textured plastic; it allows the operator to hold it firmly and apply force comfortably, especially when working in a large force or wet environment, effectively preventing hand slippage.

[0028] A positioning hole is provided on lever 5; the connecting piece 6 includes a bolt 61 that passes through the positioning hole from top to bottom; a sleeve 62 is detachably provided on the lower side of bolt 61 via a threaded connection; a pressure-bearing clamp 7 is installed on the outer wall of sleeve 62. A washer is provided between the nut portion on the top side of bolt 61 and lever 5; the function of the washer is to increase the contact area, protect the lever surface from being damaged by the nut, and prevent the bolt from loosening after repeated stress, ensuring a reliable connection; lever 5 is made of wood or steel. After bolt 61 passes through the positioning hole of the lever, it is pressed against the upper surface of the lever by its own nut and the washer, realizing the fixed connection between connecting piece 6 and lever 5; the threaded connection between sleeve 62 and bolt 61 allows the initial working height of the pressure-bearing clamp 7 to be finely adjusted by turning sleeve 62 according to the height of the windproof nail head protruding from the ground, so that it can be more accurately engaged with the nail head. When it is necessary to replace or maintain the pressure-bearing clamp 7, simply unscrew sleeve 62.

[0029] The pressure-bearing clamp 7 is an L-shaped angle steel; the limiting groove 71 is located in the middle of the lower side plate of the pressure-bearing clamp 7; reinforcing guard plates 10 are respectively provided on the left and right sides of the pressure-bearing clamp 7. In this embodiment, the back side of the pressure-bearing clamp is fixedly connected to the sleeve by welding. The reinforcing guard plates 10 are welded between the left and right sides of the horizontal plate of the angle steel and the vertical plate, which greatly enhances the bending resistance of the angle steel when subjected to huge upward pulling force and prevents its deformation and failure.

[0030] When using the utility model device in this embodiment, the following steps can be referred to for operation.

[0031] 1. Assemble lever 5 and hinge it to the top hinge hole of support block 4 using a pin or bolt through clamp plate 8; install connector 6 into the positioning hole in the middle of lever 5 and fix it; ensure that pressure bearing head 7 is below lever 5;

[0032] 2. Observe the height of the windproof nail 1 above the ground; if necessary, adjust the initial height of the pressure-bearing clamp 7 by turning the sleeve 62; the operator moves or fine-tunes the position of the device so that the limiting groove 71 of the pressure-bearing clamp 7 is inserted into the lower middle part of the windproof nail 1; then rotate the flat pad 3 to the ground near the safety triangular cone 2 fixed by the windproof nail 1; then slowly raise the lever to ensure that the nail head is locked in place in the limiting groove 71.

[0033] 3. After confirming that the windproof nail head is securely inserted into the limiting groove 71, the operator firmly grips the non-slip handle 9 and pulls the end of the lever 5 upwards; the lever 5 rotates with the top of the support block 4 as the fulcrum, and through the lever principle, a strong vertical upward pulling force will be generated at the pressure-bearing head 7; this force acts on the nail head of the windproof nail 1 through the pressure-bearing head 7 and the limiting groove 71, overcoming the friction between the windproof nail and the ground, and gradually pulling it upwards out of the ground;

[0034] 4. After the windproof nail 1 is completely pulled out, remove the windproof nail 1 from the limiting groove 71 of the pressure-bearing clamp 7; at this time, the safety triangular cone 2 can be easily moved away because it is no longer fixed, and transferred to a new bridge pier position for installation; collect all parts of the nail remover for easy transportation to the next work point; check whether all parts of the device are loose or damaged, and tighten or maintain them if necessary.
