Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to an H-shaped steel insertion auxiliary device. Background Technique

[0002] When excavating a foundation pit, in order to construct the supporting system of the foundation pit, the SMW method pile construction method will be used. The SMW method pile construction method has a simple structure and a faster construction speed compared with the traditional construction method, which can greatly reduce the construction time of the foundation pit supporting system.

[0003] In the prior art, the process of inserting the H-shaped steel is as follows: use a crane to lift the H-shaped steel to the insertion position, that is, the center of the cement mixing pile required by the design. Then, the worker uses a rope sleeve to cover and pull the bottom end of the H-shaped steel to keep it roughly vertical, and then uses a vibratory hammer to strike the top end of the H-shaped steel to vibrate it in. However, during the installation process of the H-shaped steel, a lifting device needs to be used to lift the H-shaped steel above the installation point, and the use cost of the lifting device is relatively high, which further increases the installation cost of the H-shaped steel. Therefore, a new type of H-shaped steel insertion auxiliary device needs to be proposed. Content of the Utility Model

[0022] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a kind of auxiliary device for inserting H-shaped steel, which includes an installation frame 1, and a clamping assembly 2 is fixedly connected to the outer surface of the installation frame 1; the clamping assembly 2, the clamping assembly 2 includes a support frame 201, the support frame 201 is fixedly connected to the rear surface of the installation frame 1, a motor 202 is fixedly connected to the rear surface of the support frame 201, the output end of the motor 202 rotates through the outer surface of the support frame 201, the output end of the motor 202 is fixedly connected to a threaded rod 203, a connecting frame 204 is threadedly rotatably connected to the outer surface of the threaded rod 203, a U-shaped frame 205 is fixedly connected to the front surface of the connecting frame 204, electric telescopic rods 206 are respectively fixedly connected to the outer surfaces on both sides of the U-shaped frame 205, the telescopic ends of the two electric telescopic rods 206 both slide through the outer surface of the U-shaped frame 205, and clamping plates 208 are fixedly connected to the telescopic ends of the two electric telescopic rods 206.

[0024] As Figures 1-4 shown, sliding rails 3 are symmetrically and fixedly connected to the top of the installation frame 1, sliding grooves 209 are symmetrically opened at the bottom of the U-shaped frame 205, and the sliding grooves 209 are arranged in a matching manner with the sliding rails 3. When the U-shaped frame 205 moves, the sliding grooves 209 opened at the bottom slide synchronously on the outer surface of the sliding rails 3, which plays a role in limiting and prevents the position of the U-shaped frame 205 from shifting when it moves.

[0025] As Figures 1-3 shown, a fixed seat 4 is fixedly connected to the top of the installation frame 1, and the inner surface of the fixed seat 4 is rotatably connected to the outer surface of the threaded rod 203. When the threaded rod 203 rotates, the position of the threaded rod 203 away from the motor 202 is synchronously limited and rotated in the fixed seat 4, which plays a role in support and prevents the front end of the threaded rod 203 from being unsupported and deforming.

[0026] As Figures 1-3 shown, guide rods 207 are symmetrically and fixedly connected to the outer surface of the clamping plate 208, and the guide rods 207 penetrate through the U-shaped frame 205. When the clamping plate 208 moves, the connected guide rods 207 do not slide in the inner wall of the U-shaped frame 205, which plays a role in limiting and prevents the position of the clamping plate 208 from shifting.

[0027] As Figures 1-2As shown, a plurality of mounting seats 10 are symmetrically and rotatably connected to the bottom of the mounting frame 1, and rollers 11 are rotatably connected to the inner surfaces of the plurality of mounting seats 10. When the auxiliary device is transferred, the rollers 11 rotatably connected to the inner surfaces of the plurality of mounting seats 10 roll on the ground, thereby driving the whole to move to the working location.

[0028] As Figures 1-2 shown, first connection blocks 6 are symmetrically and fixedly connected to the outer surfaces of both sides of the mounting frame 1, and hydraulic rods 5 are fixedly connected to the tops of the plurality of first connection blocks 6, which is convenient for fixedly installing the hydraulic rods 5 at the tops of the hydraulic rods 5 for use.

[0029] As Figures 1-2 shown, the telescopic end of the hydraulic rod 5 slidably penetrates through the outer surface of the first connection block 6, and a support plate 7 is fixedly connected to the telescopic end of the hydraulic rod 5. When the hydraulic rod 5 works, its telescopic end extends downward, driving the support plate 7 to abut against the ground and lifting the whole, which is convenient for suspending the clamped and fixed H-shaped steel.

[0030] As Figures 1-2 shown, second connection blocks 8 are fixedly connected to the outer surfaces of both sides of the mounting frame 1, and spirit levels 9 are arranged on the tops of the two second connection blocks 8. When the personnel adjust the lifting of the hydraulic rod 5, it is convenient to observe the horizontal parameters of the spirit levels 9 on both sides and adjust the telescoping of the hydraulic rod 5 at the corresponding position to make the mounting frame 1 tend to the horizontal position.

[0031] Usage method and working principle of this device: When using the H-beam insertion auxiliary device, push the installation frame 1, so that when multiple rollers 11 roll on the ground, they rotate synchronously inside the inner walls of multiple mounting seats 10, which plays a role in facilitating movement and makes it convenient to move the auxiliary device to the working location. Its center is located above the H-beam insertion point. Move the H-beam to the front-side notch of the installation frame 1. Synchronously start two electric telescopic rods 206. When the telescopic ends of the two electric telescopic rods 206 extend, they drive two clamping plates 208 to move towards each other. Under the sliding action of multiple guide rods 207 and the inner wall of the U-shaped frame 205, the two clamping plates 208 accurately abut against both sides of the H-beam, playing a role in clamping and fixing. Synchronously start multiple hydraulic rods 5. The telescopic ends of the multiple hydraulic rods 5 slide through the tops of multiple first connecting blocks 6 and extend downward, driving multiple support plates 7 to abut against the ground, playing a role in support and separating multiple rollers 11 from the ground, making the clamped and fixed H-beam suspended. During the support process, personnel can observe the horizontal parameters of the level 9 provided on the tops of two second connecting blocks 8 and correspondingly adjust the extension length of the hydraulic rod 5 in the direction of the lower liquid level inside the level 9 to keep the installation frame 1 in a horizontal state. Start the motor 202 fixed on the surface of the support frame 201. The output end of the motor 202 drives the threaded rod 203 to rotate forward inside the inner wall of the fixed seat 4, and the connecting frame 204 threadedly connected to it slides synchronously between the inner walls of the installation frame 1, thereby driving the U-shaped frame 205 to move backward. The U-shaped frame 205 slides along the surface of the slide rail 3 through the chute 209 opened at the bottom, so as to stably drive the clamped and fixed H-beam to move upward above the insertion point until the U-shaped frame 205 abuts against the front surface of the fixed seat 4, facilitating personnel to hammer the top of the H-beam so that it can be vertically inserted into the insertion point.

[0032] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
