Description

Technical Field

[0001] The utility model relates to the technical field of roadbed engineering, and more specifically, to a through-type pile pulling device for removing a slope skeleton template. Background Art

[0002] The conventional treatment measure for road subgrade slope treatment is to add concrete skeleton slope protection. When the slope skeleton slope protection is constructed, the template is usually installed by driving steel bars such as anchor steel bars and steel pipes. When removing the template, the steel bar is usually knocked back and forth with a hammer to reduce the friction between the steel bar and the soil, and then the steel bar is manually pulled out with a crowbar. Since the steel bar is deeply embedded in the soil, even if it is knocked out many times, the manual force is weak and it is often impossible to pull it out. The construction efficiency is very low and the labor intensity is high. Utility Model Content

[0003] One purpose of the utility model is to provide a through-type pile extraction device for dismantling a slope skeleton formwork, which is modified using existing materials on the construction site, is simple and convenient to install, and is easy to extract, greatly reducing labor intensity, improving efficiency, being safe and reliable, and having low cost.

The push plate is connected as a whole with a sleeve fixedly mounted on the push rod, and the push plate extends outward along the circumference of the body to be pulled out to form a fulcrum of the pile pulling mechanism, and the body to be pulled out is a rod body inserted into the soil and having an external thread.

[0005] Preferably, the distance between the bottoms of the pair of latches is smaller than the outer diameter of the body to be removed.

[0006] Preferably, the sleeve and the anchor plate are both threadedly connected to the push rod, and the adjustment plate is also threadedly connected to the body to be pulled out.

[0019] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement it according to the description.

[0020] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] like Figures 1 to 4 As shown, the utility model provides a through-type pile pulling device for dismantling slope skeleton formwork, comprising a pushing rod 1 and an anchor plate 2, a pushing plate 3 and an adjusting plate 4 arranged on the pushing rod, the pushing rod is sleeved on a body to be pulled 5, the adjusting plate is fixedly arranged at the bottom of the pushing rod and fixedly sleeved on the body to be pulled, the anchor plate is fixedly arranged on the top of the pushing rod, a pair of latches 6 are relatively symmetrically arranged on the inner wall of the anchor plate, the upper part of which is fixed on the inner wall of the anchor plate, the lower end of the latch is inclined downward toward the body to be pulled and is arranged tightly against the body to be pulled, the pushing plate is connected as a whole with a sleeve fixedly sleeved on the pushing rod, the pushing plate extends outward along the outer circumference of the body to be pulled to form a fulcrum of the pile pulling mechanism, and the body to be pulled is a rod body inserted into the soil and having an external thread.

[0022] The object to be pulled out is a steel bar, which is generally suitable for pulling out the steel bar when there is a certain space between the steel bar and the template. A hollow screw rod is used as a push rod, and a push rod is set in the middle of the object to be pulled out, and the push rod is used as a mounting carrier structure for the anchor plate, the push plate, the adjustment plate, and the latch. The anchor plate and the latch are installed on the upper part of the push rod, and the push rod is fixedly connected to the object to be pulled out through the limit fixation of the latch; the push plate is installed in the middle of the push rod, and the pile pulling stroke is set by the push plate; the adjustment plate is installed at the lower part of the push rod, and the push rod is fixed on the object to be pulled out through the joint action of the adjustment plate and the latch. The push rod and the object to be pulled out can also be connected by a thread. During construction, the entire pile pulling device is downwardly sleeved on the object to be pulled out, and is fixed to the object to be pulled out by rotating the thread downward, and stops after reaching the set position. The adjustment plate has a large bottom area to prevent the push rod from being inserted downward into the slope soil 7.

[0023] The object to be pulled out and the jacking rod are connected and fixed by the anchor plate, the latch pin and the adjustment plate, and the pile pulling mechanism applies force on both sides of the bottom of the jacking plate, so that the object to be pulled out can be smoothly pulled out from the soil, which greatly improves the efficiency of the skeleton formwork construction, does not require manual operation, and provides a large pile pulling force. The pile pulling mechanism includes an external crane, excavator, etc., which realizes the pile pulling through hooks or steel ropes.

[0024] In another technical solution, the distance between the bottoms of a pair of latches is smaller than the outer diameter of the body to be removed, thereby achieving fixed positioning of the body to be removed.

[0025] In another technical solution, the sleeve and the anchor plate are both threadedly connected to the push rod, and the adjustment plate is also threadedly connected to the object to be pulled, all for the purpose of adjusting the position on the push rod. The push plate is adjusted on the push rod by rotating the thread according to the position and height of the object to be pulled, that is, the distance between the applied force and the soil is adjusted.

[0026] In another technical solution, the height of the sleeve is between one-third and one-half of the height of the push rod to ensure a fixed force, and the height of the push plate is between one-fifth and one-quarter of the height of the sleeve to ensure that the push plate has a certain thickness to achieve force.

[0027] In another technical solution, the center of the anchor plate is set as a cylindrical cavity, and the height of the anchor plate anchored on the push rod does not exceed half of the height of the anchor plate to accommodate the height of the pin so that the pin can achieve the corresponding fixed positioning effect.

[0028] In another technical solution, the bottom surface of the push plate is provided with an inwardly concave groove or concave channel for engaging with a steel rope or other force-retaining member corresponding to the positioning sleeve of the pile pulling mechanism.

[0029] It can be understood that the present invention is described by some embodiments, and those skilled in the art know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation mode. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, other modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to specific details and the illustrations shown and described here.
