Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, specifically to a mechanical device for adjusting the verticality of a cement mixing pile construction machine. Background Technology

[0002] The verticality adjustment device for cement mixing pile construction is a key auxiliary equipment in cement mixing pile construction. It is mainly used to ensure that the pile driver remains vertical during construction to guarantee the quality of pile formation. Cement mixing piles are widely used as a common method for soft foundation treatment in civil engineering, highway and railway construction projects.

[0003] The verticality of the pile body is a key factor affecting the strength of the pile body and the bearing capacity of the foundation. Therefore, it is crucial to strictly control the verticality of the pile body during the pile driving process. The verticality of the pile body depends on the verticality of the drill rod, which in turn depends on the verticality of the pile driving guide frame.

[0004] In traditional construction, the plumb bob method is often used to control the verticality of the guide frame, that is, a plumb bob mechanism is set on the pile driver. However, in windy construction environments, the traction line of the plumb bob is easily affected by the wind, causing the plumb bob to sway left and right. To solve this problem, wind deflectors are usually set up. However, in reality, the plumb bob mechanism will hit the wind deflector when it sways, generating vibration. Moreover, the existing wind deflectors cannot effectively absorb energy and cannot fundamentally solve the problem, thus affecting the progress of construction work. Therefore, a mechanical device for adjusting the verticality of the pile driver in cement mixing pile construction is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mechanical device for adjusting the verticality of a cement mixing pile construction machine, in order to solve the problem that the traction line of the plumb bob is easily affected by wind force in windy construction environments, causing the plumb bob to sway left and right. To solve this problem, wind deflectors are usually installed. However, in reality, the plumb bob mechanism will hit the wind deflector when it sways, generating vibration. Moreover, the existing wind deflectors cannot effectively absorb energy and cannot fundamentally solve the problem, thus affecting the progress of construction work.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mechanical device for adjusting the verticality of a cement mixing pile construction machine includes a pile machine body. A plumb bob assembly is rotatably connected to the top of the outer wall of the pile machine body via a connecting shaft. Quick-correction components are fixedly installed on both sides inside the plumb bob assembly. The plumb bob assembly includes a connecting support, a protective shell is fixedly connected to the bottom end of the connecting support, a connecting line is fixedly connected to the center of the bottom end of the connecting support, and a plumb bob is fixedly connected to the bottom end of the connecting line. The quick-correction component includes a mounting plate, support seats are fixedly connected to both ends of the outer wall of the mounting plate, lubricating oil strips are embedded in the inner wall of the support seats, a cantilevered elastic spring is slidably fitted between the two support seats, a correction seat is fixedly connected to the middle of the outer wall of the cantilevered elastic spring, a shaft tube is fixedly connected through the rear end of the correction seat, a pressure ring is fixedly connected to the rear end of the shaft tube, an oil reservoir is fixedly connected to the middle of the outer wall of the mounting plate, and an oil-absorbing sponge is embedded inside the oil reservoir. The connecting line extends into the interior of the correction seat.

[0008] As a further optimization of this utility model, the inner side of the correction seat has an arc-shaped structure, there is a gap between the correction seat and the connecting line, an adsorption layer is fixedly connected to the inner side of the correction seat, and the adsorption layer is in contact with the front end of the shaft tube.

[0009] As a further optimization of this utility model, the shaft tube and the pressure ring are located on the same central axis, the shaft tube and the pressure ring are interconnected, the rear end of the shaft tube extends into the interior of the oil storage tank, and the shaft tube and the oil storage tank are slidably connected.

[0010] As a further optimization of this utility model, the front end of the oil storage shell has an arc-shaped structure, there is a gap between the oil storage shell and the shaft tube, and the oil-absorbing sponge is located behind the pressure ring.

[0011] As a further optimization of this utility model, the length of the lubricating oil cotton strip is adapted to the length of the mounting plate, the lubricating oil cotton strip is bonded and fixed to the mounting plate, the lubricating oil cotton strip extends into the interior of the oil reservoir, and the lubricating oil cotton strip is in close contact with the oil-absorbing sponge.

[0012] As a further optimization of this utility model, the quick-correction components arranged on both sides inside the protective shell are symmetrically distributed with the connecting line as the center. The number of quick-correction components is set to multiple, and the multiple quick-correction components are arranged linearly. The plumb bob is located below the protective shell.

[0013] As a further optimization of this utility model, a wind baffle is fixedly connected to the outer wall of the plumb bob assembly. The outer side of the wind baffle has an arc-shaped structure, and there is a gap between the side of the wind baffle and the outer wall of the pile driver body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the verticality of the pile driver is effectively adjusted by using a plumb bob assembly and a quick-correction assembly. The connecting line causes the correction seat to squeeze the cantilevered elastic spring, which in turn moves the shaft tube to squeeze the oil-absorbing sponge, squeezing out lubricating oil and reducing the friction between the correction seat and the connecting line, and between the cantilevered elastic spring and the support seat. Multiple quick-correction assemblies work together to quickly absorb and weaken the swaying energy of the connecting line, accelerating the correction and allowing the plumb bob assembly to return to a vertical state as soon as possible. This design avoids the problems of traditional wind deflectors failing to effectively absorb energy and easily generating vibrations, fundamentally solving the problem of the plumb bob swaying due to wind force, ensuring the progress of construction work, improving the accuracy and stability of the pile driver's verticality adjustment, and guaranteeing construction quality and efficiency.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0027] Please see Figures 1-6 This utility model provides a technical solution:

[0028] A mechanical device for adjusting the verticality of a cement mixing pile construction machine includes a pile driver body 1. A plumb bob assembly 2 is rotatably connected to the top of the outer wall of the pile driver body 1 via a connecting shaft. Quick-correction components 3 are fixedly installed on both sides inside the plumb bob assembly 2. The plumb bob assembly 2 includes a connecting support 21, a protective shell 22 is fixedly connected to the bottom end of the connecting support 21, a connecting line 23 is fixedly connected to the center of the bottom end of the connecting support 21, and a plumb bob body 24 is fixedly connected to the bottom end of the connecting line 23. The quick-correction components 3 include a mounting plate 31, with both ends of the outer wall of the mounting plate 31... A support base 32 is fixedly connected, and a lubricating oil cotton strip 33 is embedded in the inner wall of the support base 32. A cantilever elastic spring 34 is slidably engaged between the two support bases 32. A correction base 35 is fixedly connected to the middle of the outer wall of the cantilever elastic spring 34. A shaft tube 36 is fixedly connected through the rear end of the correction base 35. A pressure ring 37 is fixedly connected to the rear end of the shaft tube 36. An oil reservoir 38 is fixedly connected to the middle of the outer wall of the mounting plate 31. An oil-absorbing sponge 39 is embedded in the inner side of the oil reservoir 38. The sponge 39 is located behind the pressure ring 37. The connecting line 23 extends into the interior of the correction base 35.

[0029] As a further implementation of this solution, the quick-correction components 3 arranged on both sides inside the protective shell 22 are symmetrically distributed on the left and right with the connecting line 23 as the center. There are multiple quick-correction components 3, which are arranged linearly. The plumb bob 24 is located below the protective shell 22.

[0030] As a further implementation of this solution, the inner side of the correction seat 35 has an arc-shaped structure, and there is a gap between the correction seat 35 and the connecting line 23. An adsorption layer 5 is fixedly connected to the inner side of the correction seat 35. The adsorption layer 5 is attached to the front end of the shaft tube 36, which can correct the swinging connecting line 23 from multiple positions at the same time, improving the balance and comprehensiveness of the correction.

[0031] As a further implementation of this solution, the shaft tube 36 and the pressure ring 37 are located on the same central axis and are interconnected. The rear end of the shaft tube 36 extends into the interior of the oil reservoir 38, and the shaft tube 36 and the oil reservoir 38 are slidably connected. The front end of the oil reservoir 38 has an arc-shaped structure, and there is a gap between the oil reservoir 38 and the shaft tube 36, which provides space for the shaft tube 36 to move and can effectively accommodate the lubricating oil.

[0032] As a further implementation of this solution, the length of the lubricating cotton strip 33 is adapted to the length of the mounting plate 31. The lubricating cotton strip 33 is bonded and fixed to the mounting plate 31. The lubricating cotton strip 33 extends into the interior of the oil reservoir 38. The lubricating cotton strip 33 is in contact with the oil-absorbing sponge 39. The lubricating cotton strip 33 of the appropriate length can fully cover the contact area between the cantilever elastic spring 34 and the support base 32. The bonding and fixing method ensures its positional stability. A continuous and uniform oil film is formed between the spring 34 and the support base 32, which effectively reduces the friction between the two, extends the service life of the cantilever elastic spring 34, and ensures the long-term stable operation of the entire quick correction assembly 3.

[0033] Workflow: If the connecting line 23 in the plumb bob assembly 2 swings left and right due to factors such as wind, the force generated by the swing of the connecting line 23, which extends into the straightening seat 35, will cause the straightening seat 35 to move closer to the mounting plate 31, thereby squeezing the cantilevered elastic spring 34 and deforming it. The deformation of the cantilevered elastic spring 34 will also drive the shaft tube 36 to move. Because the shaft tube 36 and the oil reservoir 38 are slidably connected, the movement is accurate without obstructing the effective extension of the contact points between the two ends of the cantilevered elastic spring 34 and the support seat 32. The movement of the shaft tube 36 will squeeze the oil-absorbing sponge 39 inside the oil reservoir 38 through the pressure ring 37. After being squeezed, the oil-absorbing sponge 39 will have its absorbed lubricating oil squeezed out, and the lubricating oil will be transported through the shaft tube 36 and the pressure ring 37. The oil-absorbing sponge 39 absorbs oil, thereby correcting the friction between the seat 35 and the connecting line 23. At the same time, the lubricating oil in the oil-absorbing sponge 39 will pass through the oil-absorbing cotton strip 33. Since the oil-absorbing cotton strip 33 is embedded in the inner wall of the support seat 32 and extends into the oil storage shell 38, the oil-absorbing cotton strip 33 has good adsorption properties, so that the lubricating oil forms an oil film between the cantilever elastic spring 34 and the support seat 32, thereby reducing the friction between the cantilever elastic spring 34 and the support seat 32, ensuring the effectiveness and service life of the cantilever elastic spring 34. Through the cooperation of multiple quick correction components 3, the energy generated by the swing of the connecting line 23 is quickly absorbed and weakened, the correction of the swing problem is accelerated, and the plumb bob assembly 2 is restored to the vertical state as soon as possible, thereby achieving effective adjustment of the verticality of the pile driver.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
