Description

Technical Field

[0001] The invention belongs to the technical field of pile pipe installation, and in particular relates to a novel installation device for installing a steel column. Background Art

[0002] There are two methods for constructing steel guardrail columns: excavation method and driving method. Currently, most steel guardrail column construction adopts the driving method, which uses a pile driver to hammer the steel guardrail column to smash the steel guardrail into the elevation position. However, the traditional pile driver construction directly hammers the hammer head on the end of the steel column to be hammered, which can easily cause damage to the mouth of the steel column, thereby affecting the use of the steel column; therefore, we propose a new installation device for installing steel columns to solve the above problems. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a new installation device for installing steel columns, which solves the problem that the traditional pile driver easily causes damage to the mouth of the steel column.

[0004] The present invention is implemented by the following scheme: A new type of installation device for installing a steel column, comprising:

[0005] Carrying equipment;

[0006] A guide rail arranged vertically on the carrying device;

[0007] A limit ring is slidably arranged along the guide rail for vertical insertion of the end of the steel column to be hammered, and a plurality of notches are arranged at intervals along the annular direction on the inner wall of the limit ring, and each of the notches is arranged along the vertical length;

[0008] An impact ring, wherein the outer wall of the impact ring is matched with the inner wall of the limit ring, the inner wall of the impact ring is in a tapered shape with a small top and a large bottom, and the diameter of the small end is smaller than the diameter of the end to be hammered, so that when the impact ring is in close contact with the limit ring and the end to be hammered, the top of the impact ring is higher than the top of the end to be hammered, and the impact ring comprises a plurality of steel wedges which can be respectively inserted into the plurality of notches, each of the steel wedges is thick at the upper end and thin at the lower end, and the inner side of each steel wedge is sloped from top to bottom, and the plurality of steel wedges enclose the impact ring;

[0009] An impact hammer disposed above the limiting ring is used to hammer the tops of the plurality of steel wedges, so that the plurality of steel wedges drive the hammered ends to move downward, thereby pressing the steel column into the soil; and

[0010] The returner connected to the outer side of the limit ring is used for pushing the multiple steel wedges upward in a shaking manner to loosen the multiple steel wedges.

[0011] A further improvement of the novel installation device for installing steel columns of the present invention is that the impact hammer includes a first driving device fixed on the guide rail and a hammer head connected to the output end of the first driving device; the novel installation device also includes a connecting piece detachably connected to the hammer head and the limit ring to meet the requirement that when the hammer head rises under the drive of the first driving device, the limit ring is pulled up through the connecting piece.

[0012] A further improvement of the novel installation device for installing steel columns of the present invention is that the connecting piece includes a side plate connected to the hammer head at the first end, a first plug hole penetrating along the thickness direction of the second end of the side plate, a second plug hole opened on the outside of the limiting ring, and a bolt, wherein the bolt passes through the first plug hole and is inserted into the second plug hole to connect the hammer head and the limiting ring together.

[0013] A further improvement of the novel installation device for installing steel columns of the present invention is that the impact ring also includes a rubber layer arranged in a circle between the multiple steel wedges and the end to be hammered, and the rubber layer is fixedly connected to the inner wall of the limit ring to achieve close contact between the impact ring, the limit ring and the end to be hammered.

[0014] A further improvement of the novel installation device for installing steel columns of the present invention is that the returner includes a hydraulic vibrator fixed to the outside of a limiting ring, a shaking rod connected to the output shaft of the hydraulic vibrator, and a shaking plate connected to the end of the shaking rod away from the hydraulic vibrator. The shaking rod is driven by the hydraulic vibrator to drive the shaking plate to shake up and down, so that the shaking plate shakes upward to push the multiple steel wedges and loosen the multiple steel wedges in the corresponding grooves respectively.

[0015] A further improvement of the novel installation device for installing steel columns of the present invention is that the guide rail is rotatably connected to the bearing device via a rotating shaft, and a second driving device for driving the rotating shaft to rotate is fixed to the bearing device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention uses an impact hammer to hammer the top of the impact ring. Since the outer wall of the impact ring is matched with the inner wall of the limiting ring, the inner wall of the impact ring is in a cone shape with a small top and a large bottom, and the diameter of the small end is smaller than the diameter of the end to be hammered, so when the impact ring is hammered, multiple steel wedges will drive the end to be hammered to move downward and then press the steel column into the soil. Compared with the traditional method of directly hammering the mouth of the steel column, the present invention can avoid damaging the mouth of the steel column; through the set return device, when working, it can shake and push multiple steel wedges upward to loosen them, so as to push the limiting ring upward, so that the end to be hammered of the steel column is separated from the limiting ring, and then the whole device can be moved to the next steel column for construction, which is simple and convenient to operate.

DETAILED DESCRIPTION

[0023] In order to solve the problem that the traditional pile driver easily causes damage to the mouth of the steel column, the present invention provides a new installation device for installing the steel column. The new installation device for installing the steel column is further described below with specific embodiments combined with the accompanying drawings.

[0024] See also Figure 1 to Figure 4 As shown, a new installation device for installing a steel column comprises:

[0025] Carrying equipment (not shown in the figure);

[0026] A guide rail 1 is vertically arranged on the carrying device;

[0027] A limit ring 5 is slidably arranged along the guide rail 1 for vertical insertion of the end of the steel column 8 to be hammered. A plurality of notches 10 are arranged at intervals along the annular direction on the inner wall of the limit ring 5, and each notch 10 is arranged along the vertical length;

[0028] An impact ring 6, wherein the outer wall of the impact ring 6 is matched with the inner wall of the limiting ring 5, the inner wall of the impact ring 6 is in a tapered shape with a small top and a large bottom, and the diameter of the small end is smaller than the diameter of the end to be hammered, so that when the impact ring 6 is in close contact with the limiting ring 5 and the end to be hammered, the top of the impact ring 6 is higher than the top of the end to be hammered, and the impact ring 6 includes a plurality of steel wedges 601 that can be respectively inserted into the plurality of notches 10, each of the steel wedges 601 is thick at the upper end and thin at the lower end, and the inner side of each steel wedge 601 is sloped from top to bottom, and the plurality of steel wedges 601 enclose and form the impact ring 6;

[0029] The impact hammer 3 disposed above the limiting ring 5 is used to hammer the tops of the plurality of steel wedges 601, so that the plurality of steel wedges 601 drive the hammered ends to move downward and thus press the steel column 8 into the soil; and

[0030] The returner 7 connected to the outer side of the limiting ring 5 is used to push the multiple steel wedges 601 upward in a shaking manner to loosen the multiple steel wedges 601.

[0031] By setting the top of the impact ring 6 higher than the top of the end to be hammered, when the impact hammer 3 strikes, it will directly hang on the top of the impact ring 6, and will not strike the top of the end to be hammered of the steel column 8. When hammering the impact ring 6, the impact ring 6 will exert downward pressure on the end to be hammered of the steel column 8, thereby pressing the steel column 8 into the soil, avoiding direct contact between the impact hammer 3 and the steel column 8, and avoiding damage to the mouth of the steel column; and after the steel column 8 is installed, the return device 7 can be used to shake and push multiple steel wedges 601 upward to loosen the multiple steel wedges 601, and then the limit ring 5 can be raised to separate from the end to be hammered, which is simple to operate and easy to use.

[0032] Among them, see Figure 1 As shown, the impact hammer 3 includes a first driving device 301 fixed on the guide rail 1 and a hammer head 302 connected to the output end of the first driving device 301; the new installation device also includes a connecting member 4 detachably connected to the hammer head 302 and the limiting ring 5, so as to meet the requirement that when the hammer head 302 rises under the drive of the first driving device 301, the limiting ring 5 is pulled up through the connecting member 4.

[0033] Specifically, the first driving device 301 may be a hydraulic driving system, which mainly controls the hammer head 302 to continuously rise and fall, so as to use the hammer head 302 to hammer the top of the impact ring 6, and when hammering the impact ring 6, the connecting member 4 and the limiting ring 5 are in a disassembled state;

[0034] Through the operation of the return device 7, multiple steel wedges 601 can be pushed upward in a shaking manner to loosen the multiple steel wedges 601, and the limit ring 5 is connected to the hammer head 302 by the connecting piece 4, and the hammer head 302 is driven to rise by the first driving device 301. The limit ring 5 can be pulled up by the connecting piece 4, so that the limit ring 5 and the end to be hammered of the steel column 8 are separated; if the steel column 8 is installed incorrectly and needs to be pulled out, the impact hammer 3 can be used to make the multiple steel wedges 601 close to the end to be hammered of the steel column 8, and then the hammer head 302 is driven to rise by the first driving device 301, and the limit ring 5 can be pulled up by the connecting piece 4, and the contact friction between the multiple steel wedges 601 and the limit ring 5 and the end to be hammered of the steel column 8 can be used to pull the steel column 8 out of the soil.

[0035] Among them, see Figure 1-2As shown, the connecting member 4 includes a side plate 401 connected to the hammer head 302 at the first end, a first socket penetrating along the thickness direction of the second end of the side plate 401, a second socket 403 opened on the outside of the limiting ring 5, and a plug 402. The plug 402 passes through the first socket and is inserted into the second socket 403 to connect the hammer head 302 and the limiting ring 5 together.

[0036] The plug 402 is provided to cooperate with the first socket and the second socket 403, so the structure is simple and the operation is convenient.

[0037] Among them, see Figure 3 As shown, the impact ring 6 also includes a rubber layer 9 that is padded between the multiple steel wedges 601 and the end to be hammered. The rubber layer 9 is fixedly connected to the inner wall of the limiting ring 5 to achieve a close fit between the impact ring 6, the limiting ring 5 and the end to be hammered.

[0038] For details, see Figure 4 As shown, each steel wedge 601 is connected to a hammer cap 602 at the top and the bottom. The hammer cap 602 at the top is used for the hammer head 302 to hammer, and the hammer cap 602 at the bottom is used for the return device 7 to push. The hammer cap 602 at the top and the hammer cap 602 at the bottom limit the steel wedge 601 in the slot 10, so as to prevent the steel wedge 601 from moving vertically out of the slot 10.

[0039] By setting a rubber layer 9 to seal the opening of the notch 10 toward the inside, the multiple steel wedges 601 are separated from the end of the steel column 8 to be hammered. When the impact hammer 3 hammers the hammer cap 602 on the top of the multiple steel wedges 601, the rubber layer 9 is tightly attached between the multiple steel wedges 601 and the end to be hammered, which can prevent the multiple steel wedges 601 from directly contacting the end to be hammered of the steel column 8, and avoid the appearance of excessive weight on the end to be hammered of the steel column 8, thereby achieving a buffering and protective effect.

[0040] Among them, see Figure 3 As shown, the returner 7 includes a hydraulic vibrator fixed on the outside of the limiting ring 5, a shaking rod 701 connected to the output shaft of the hydraulic vibrator, and a shaking plate 702 connected to the end of the shaking rod 701 away from the hydraulic vibrator. The shaking rod 701 is driven by the hydraulic vibrator to drive the shaking plate 702 to shake up and down, so that the shaking plate 702 shakes upward to push the multiple steel wedges 601 and make the multiple steel wedges 601 loose in the corresponding slots 10 respectively.

[0041] For details, see Figure 3 As shown, there are multiple shaking rods 701, and the returner 7 also includes multiple mounting blocks 704 arranged along the outer periphery of the lower end of the limiting ring 5, multiple through holes respectively penetrating the multiple mounting blocks 704 and for the ends of the multiple shaking rods 701 connected to the output shaft of the hydraulic vibrator to pass through, and a through hole 703 penetrating along the thickness direction of the shaking plate 702, and the end of the steel column 8 to be hammered can be directly inserted into the limiting ring 5 through the through hole 703;

[0042] By starting the hydraulic vibrator to drive multiple shaking rods 701 to shake, thereby driving the shaking plate 702 to shake, the shaking plate 702 will be used to push the hammer caps 602 at the bottom of multiple steel wedges 601 upward, thereby loosening the multiple steel wedges 601, making it easier to control the limit ring 5 to separate from the hammer end of the steel column 8.

[0043] The guide rail 1 is rotatably connected to the carrying device via a rotating shaft 2, and a second driving device (not shown in the figure) for driving the rotating shaft 2 to rotate is fixed to the carrying device.

[0044] Specifically, the carrying device may be a mobile trolley to facilitate the movement of the entire device; the second driving device may be a motor;

[0045] By starting the second driving device to drive the rotating shaft 2 to rotate, the rotation angle of the entire new installation device can be controlled to adapt to the installation work of the steel column 8 at different angles.
