Description

Technical Field

[0001] The utility model belongs to the technical field of steel sheet pile construction, and particularly relates to an auxiliary device for pulling out steel sheet piles in a highly sensitive soil site. Background Art

[0002] Steel sheet piles have the advantages of high strength, light weight, stable performance, convenient construction, transportation and maintenance, fast construction speed, easy quality control, short construction period, and clean construction site. After the construction is completed, the steel sheet piles need to be pulled out. For example, a steel sheet pile pulling-out device for buildings with the patent number CN201721131173.2 includes a frame, a pulling cylinder is fixed at the upper end of the frame, a cam plate is fixed on one side of the frame, and a compression spring and other components are also fixed on the other side of the frame.

[0003] In the above prior art, the pulling cylinder and the clamping block are arranged on a vertical line. The disadvantage of this is that when the length of the steel sheet pile is long, the pulled-out part of the steel sheet pile is likely to interfere with the frame or the pulling cylinder, resulting in the problem that the latter half of the steel sheet pile cannot be pulled out (of course, the frame can be heightened, but this method is not economical and practical). That is, the setting method in the prior art can only perform the pulling-out operation on steel sheet piles with a short length. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide an auxiliary device for pulling out steel sheet piles in a highly sensitive soil site, so as to solve the problem that the pulled-out part of the steel sheet pile is likely to interfere with the pulling-out device when the existing steel sheet pile pulling-out device performs the pulling-out operation on a longer steel sheet pile.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An auxiliary device for pulling out steel sheet piles in a highly sensitive soil site of the utility model includes an installation base plate. One side surface of the installation base plate is provided with an installation vertical plate. One end of the installation vertical plate is fixed on the installation base plate. The other end of the installation vertical plate is provided with a hydraulic rod. The cylinder end of the hydraulic rod is fixed on the installation vertical plate. The output end of the hydraulic rod is provided with a connecting rod. One end of the connecting rod is rotatably connected to the output end of the hydraulic rod. The other end of the connecting rod is provided with a clamping jaw for clamping the steel sheet pile. The installation base plate is also provided with a deflection mechanism. When the hydraulic rod drives the connecting rod to move upward, the connecting rod swings under the action of the deflection mechanism.

[0007] Furthermore, the deflection mechanism includes a first wavy guide plate and a second wavy guide plate disposed on both sides of the connecting rod. One end of the first wavy guide plate and the second wavy guide plate is fixed to the vertical plate, and the sides of the first wavy guide plate and the second wavy guide plate provided with wavy patterns are disposed opposite to each other, and the wavy patterns of the first wavy guide plate and the second wavy guide plate are staggered.

[0008] Furthermore, a first fixing plate is provided on the output end of the hydraulic rod. A second fixing plate is provided below the first fixing plate. An installation column is provided in the middle of the second fixing plate. One end of the connecting rod is rotatably connected to the installation column, and the first fixing plate and the second fixing plate are detachably connected.

[0009] Furthermore, a plurality of bolt holes are provided at the edges of the first fixing plate and the second fixing plate. Screws are provided in the bolt holes. Nuts are fixedly provided on the outer sides of the bolt holes of the second fixing plate, and the screws and the nuts are threadedly connected.

[0010] Furthermore, a baffle is provided on the edge of the mounting base plate below the jaw. One end of the baffle is fixed to the mounting base plate. A U-shaped through groove is provided at the other end of the baffle, and a blocking rod is detachably connected to the open end of the U-shaped through groove.

[0011] Furthermore, a rubber anti-slip layer is provided on the side surface of the jaw in contact with the steel sheet pile.

[0012] Furthermore, the wavy patterns of the first wavy guide plate and the second wavy guide plate are both provided with smooth transitions.

[0013] Furthermore, a plurality of connecting rib plates are provided between the cylinder body portion of the hydraulic rod and the mounting vertical plate, and both ends of the connecting rib plates are respectively fixed to the cylinder body of the hydraulic rod and the mounting vertical plate.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In this technical solution, the jaw and the hydraulic rod are connected by a connecting rod, so that the jaw and the hydraulic rod are not on the same vertical line, that is, they are staggered. That is, after the steel sheet pile is lifted to a certain height, the height of the steel sheet pile will not form a moving interference with the upper end of the hydraulic rod or the mounting vertical plate. Furthermore, the device can perform the pulling-out operation on the steel sheet pile with a longer length.

[0016] Other advantages, objectives and features of the present utility model will be described in the subsequent specification, and to some extent, they are obvious to those skilled in the art, or those skilled in the art can be taught from the practice of the present utility model. The objectives and other advantages of the present utility model can be achieved and obtained through the following specification. Description of the Drawings

Specific embodiments

[0023] As Figures 1 - 3 shown, an extraction assistance device for a steel sheet pile 15 in a highly sensitive soil site of the present utility model includes an installation bottom plate 1. It is not difficult to understand that the surface area of the side of the installation bottom plate 1 in contact with the highly sensitive soil site should be relatively large so as to have a better contact support effect. An installation vertical plate 2 is provided on one side of the installation bottom plate 1. One end of the installation vertical plate 2 is fixed to the installation bottom plate 1, and a hydraulic rod 3 is provided at the other end of the installation vertical plate 2. The cylinder end of the hydraulic rod 3 is fixed to the installation vertical plate 2, and a connecting rod 11 is provided at the output end of the hydraulic rod 3. One end of the connecting rod 11 is rotatably connected to the output end of the hydraulic rod 3, and a claw 12 is provided at the other end of the connecting rod 11. The claw 12 is used to clamp the steel sheet pile 15. A deflection mechanism is also provided on the installation bottom plate 1. When the hydraulic rod 3 drives the connecting rod 11 to move upward, the connecting rod 11 swings under the action of the deflection mechanism.

[0024] The working principle of this technical solution is:

[0025] Install the plate device on the ground, and then clamp the end of the steel sheet pile 15 with the clamping jaw 12. After clamping, drive the clamping jaw 12 to move upward through the lifting action of the hydraulic rod 3, thereby lifting the steel sheet pile 15 upward. After lifting to the limit stroke position of the hydraulic rod 3, it is only necessary to release the clamping jaw 12, reset the hydraulic rod 3, and then continue with clamping and lifting. In this technical solution, the advantage of connecting the clamping jaw 12 and the hydraulic rod 3 through the connecting rod 11 is that the clamping jaw 12 and the hydraulic rod 3 are not on the same vertical line. That is, after lifting the steel sheet pile 15 to a certain height, the height of the steel sheet pile 15 will not form a moving interference with the upper end of the hydraulic rod 3 or the installation vertical plate 2. Therefore, this device can perform the extraction operation on the steel sheet pile 15 with a longer length.

[0026] In an implementable manner, the deflection mechanism includes a first corrugated guide plate 16 and a second corrugated guide plate 17 arranged on both sides of the connecting rod 11. One end of the first corrugated guide plate 16 and the second corrugated guide plate 17 is fixed to the vertical plate, and the sides of the first corrugated guide plate 16 and the second corrugated guide plate 17 provided with corrugated patterns (it should be noted that the corrugated pattern is a pattern composed of several grooves and protrusions) are arranged opposite to each other. The corrugated patterns of the first corrugated guide plate 16 and the second corrugated guide plate 17 are arranged staggeredly. The so-called staggered arrangement here means, for example, that the protruding part of the first corrugated guide plate 16 is arranged opposite to the groove part of the second corrugated guide plate 17.

[0027] When the connecting rod 11 moves upward, since the connecting rod 11 is rotatably connected to the hydraulic rod 3, under the blocking and guiding action of the protrusion of the first corrugated guide plate 16, it will drive the connecting rod 11 to deflect towards the second corrugated guide plate 17. During the upward movement after deflection, it is blocked and guided by the protrusion of the second corrugated guide plate 17, and then deflects towards the first corrugated guide plate 16. Therefore, during the upward movement of the connecting column, it will continuously swing left and right, thereby driving the steel sheet pile 15 to swing left and right, thereby reducing the friction between the steel sheet pile 15 and the ground, and making it easier to extract the steel sheet pile 15. Of course, the deflection mechanism can be realized by means of a telescopic hydraulic rod or other ways to reciprocally drive the connecting rod 11 to move.

[0028] In an implementable manner, a first fixing plate 4 is provided at the output end of the hydraulic rod 3. A second fixing plate 6 is provided below the first fixing plate 4. An installation column 10 is provided in the middle of the second fixing plate 6. One end of the connecting rod 11 is rotatably connected to the installation column 10. The first fixing plate 4 and the second fixing plate 6 are detachably connected. This way of rotational connection is simple and convenient for installation and disassembly.

[0029] In an implementable manner, a plurality of bolt holes (the first bolt holes 7 and the second bolt holes 8 respectively) are provided at the edges of the first fixed plate 4 and the second fixed plate 6. A screw rod 5 (which can be understood as a common fixing bolt) is provided in the bolt holes. A nut 9 is fixedly provided on the outer side surface of the bolt holes of the second fixed plate 6. The screw rod 5 and the nut 9 are in threaded connection, and the connection between the bolt and the nut 9 is simple.

[0030] In an implementable manner, a baffle 13 is provided on the edge of the mounting base plate 1 below the jaw 12. One end of the baffle 13 is fixed to the mounting base plate 1, and a U-shaped through groove is provided at the other end of the baffle 13. A blocking rod 14 is detachably connected to the open end of the U-shaped through groove. The setting of the U-shaped through groove and the blocking rod 14 on the baffle 13 can limit and block the sheet pile 15 therein, so that the sheet pile 15 can only move upward, reducing the problem that the sheet pile 15 is about to be pulled out of the ground, and at this time the hydraulic rod 3 needs to release the jaw 12 to reset, resulting in tilting and falling, causing potential safety hazards.

[0031] In an implementable manner, a rubber anti-slip layer is provided on the side surface of the jaw 12 in contact with the sheet pile 15, improving the clamping effect and stability.

[0032] In an implementable manner, the wavy patterns of the first wavy guide plate 16 and the second wavy guide plate 17 are both set with smooth transitions, which can reduce the friction force in contact with the connecting rod 11 and improve the effect of the upward movement of the connecting rod 11.

[0033] In an implementable manner, a plurality of connecting rib plates 18 are provided between the cylinder body part of the hydraulic rod 3 and the mounting vertical plate 2. The two ends of the connecting rib plate 18 are respectively fixed to the cylinder body of the hydraulic rod 3 and the mounting vertical plate 2, improving the stability of the hydraulic rod 3 fixed on the mounting vertical plate 2.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
