Description

[0002] At present, China is vigorously developing infrastructure, especially in the field of bridge engineering. Therefore, the application of large-diameter bored piles is becoming more and more extensive. Since the pile foundation is a concealed project, there are many factors that affect the quality of pile foundation construction, such as complex geological factors, drilling process selection, lowering of wall-mounted steel cages, concrete mixing, transportation and pouring, etc. Therefore, if there is a little carelessness or the construction measures are not implemented in place, it is easy to cause drilling or pouring safety and quality accidents, even hole collapse, diameter shrinkage and other problems, which may cause damage to the pile foundation or even waste of piles.

[0003] Based on the above factors, when drilling and pouring bridge holes, a slag cleaning device is needed to clean the borehole. In the prior art, a slag suction pump is generally used as the slag cleaning device. When the slag suction pump is used to clean the borehole, it is usually necessary to fix a catheter at the lower end of the slag suction pump, and then perform the slag suction operation by placing the catheter into the borehole. However, when specifically combining the slag suction pump and the catheter, manual assistance is usually required to align the slag suction pump and the catheter before combining and fixing them. Although the slag suction pump can be suspended in the air, the slag suction pump will move around during the suspension process, and it is often still necessary to specially configure personnel to stabilize the slag suction pump, and the staff who pick up the catheter needs to work together with the staff who stabilize the slag suction pump, which makes it difficult to align and assemble quickly, and it is also more laborious for the staff.

Due to the provision of the assembly and disassembly component, the constraint cylinder of the assembly and disassembly component is coaxially covered on the periphery of the slag suction pump body, so that the slag suction pump body can be lifted from bottom to top, passed through the constraint cylinder and stably limited. At the same time, the outlet pipe of the slag suction pump body can slide vertically from bottom to top along the limit groove until it contacts the top of the limit groove, so that the slag suction pump body can be restricted from moving around. The suspended limit and anti-movement method of the slag suction pump body is simple and easy to implement, instead of the operation method of configuring personnel to hold it steady, ensuring that The slag suction pump body can be assembled and disassembled with the slag suction guide tube without moving randomly. After the slag suction pump body is restricted in place, the motor seat and the storage tube are driven to rise by the lifting adjustment member below, so that the slag suction guide tube coaxially placed inside the storage tube can be coaxially aligned with the connecting pipe mouth of the slag suction pump body.

Moreover, since the limiting sleeve is coaxially fixed to the outer periphery of the guide rod of the longitudinal drive assembly, the limiting sleeve can be pressed against the limiting sleeve by the guide seat to limit the movement of the constraint cylinder to be exactly coaxial with the storage cylinder, thereby further facilitating the combination and separation operation of the slag suction pump body and the slag suction catheter after the coaxial alignment of the constraint cylinder and the storage cylinder.

[0015] The beneficial effects are as follows: 1. The present invention is provided with an assembly and disassembly component, so that the slag suction pump body can be lifted from bottom to top through the constraint cylinder and stably limited by the way that the constraint cylinder of the assembly and disassembly component is coaxially covered on the periphery of the slag suction pump body, and at the same time, the outlet pipe of the slag suction pump body slides vertically from bottom to top along the limit groove until it contacts the top of the limit groove, so that the slag suction pump body cannot move randomly, and the suspension limit and anti-movement method of the slag suction pump body is simple and easy to implement, replacing the operation method of configuring personnel to stabilize, ensuring that the slag suction pump body can not move randomly during the process of assembly and disassembly with the slag suction guide tube; 2. After the slag suction pump body is restricted in place, the lifting adjustment member below drives the motor seat and the storage barrel to rise so that the slag suction conduit coaxially placed inside the storage barrel can be coaxially aligned with the connecting pipe opening of the slag suction pump body. At the same time, the second driving motor drives the storage barrel to rotate forward and the lifting wing seat to rise vertically along the support stud so that the slag suction conduit can be quickly combined with the connecting pipe opening by twisting forward. Moreover, the second driving motor drives the storage barrel to rotate reversely and the lifting wing seat to descend vertically along the support stud so that the slag suction conduit can be quickly separated from the connecting pipe opening by twisting reversely. The combination and separation of the slag suction conduit and the slag suction pump body are simple and easy to realize, replacing the operation mode of staff-assisted comparison and manual combination and separation, which is convenient to operate and conducive to improving the slag cleaning efficiency of the borehole. 3. The driving motor of the longitudinal drive assembly drives the screw rod to rotate, which can drive the constraint cylinder and the slag suction pump body to move longitudinally together. After the slag suction pump body and the slag suction guide tube are assembled, it is convenient to move it to the position above the object opening by longitudinal forward movement and then lower it to perform the slag cleaning operation at the drilling position. At the same time, after the slag cleaning at the drilling position is completed, it is convenient to move it to the position directly above the object placement cylinder by longitudinal backward movement and then perform the separation operation of the slag suction pump body and the slag suction guide tube; 4. A limiting sleeve is coaxially fixed on the periphery of the guide rod of the longitudinal drive assembly, and then the guide seat is pressed against the limiting sleeve to enable the constraint cylinder to be limitedly moved to be exactly coaxial with the storage cylinder, thereby further facilitating the combination and disassembly of the slag suction pump body and the slag suction guide tube after the constraint cylinder and the storage cylinder are coaxially aligned.

Specifically, the longitudinal movement drive component 2 includes a U-shaped support 1 203 and a U-shaped support 207, and the U-shaped support 1 203 and the U-shaped support 207 are respectively arranged along The U-shaped support 1 203 and the bottom surface of the U-shaped support 207 are both suspended and fixed above the corresponding side of the top surface of the base 4 through a plurality of vertical support rods 206. A driving motor 1 201 is fixed to the back of the vertical part of the rear of the U-shaped support 1 203 along the longitudinal direction. The motor shaft 1 202 at the front of the driving motor 1 201 passes through the rear vertical part of the U-shaped support 1 203 in a longitudinal sliding manner and is coaxially fixed with a screw rod 204 through a coupling. At the same time, the screw rod 204 is arranged along the longitudinal direction and the front end The bearing seat 2011 is rotatably connected with the vertical part of the front part of the U-shaped support 1 203, and the outer periphery of the screw rod 204 is inserted and sleeved with a nut seat 205 in a threaded matching manner. A guide rod 2010 is fixed longitudinally between the front and rear vertical parts of the U-shaped support 207, and the outer periphery of the guide rod 2010 is inserted and sleeved with a guide seat 209 in a longitudinal sliding matching manner, and the outer ends of the connecting arms 301 at the two sides are respectively fixed to the outer peripheries of the nut seat 205 and the guide seat 209 that are close to each other. The purpose of this arrangement is to drive the longitudinal movement The driving motor 201 of component 2 drives the screw rod 204 to rotate, which can drive the constraint cylinder 302 and the slag suction pump body 1 to move longitudinally together. After the slag suction pump body 1 and the slag suction catheter 103 are combined, it is convenient to move it to the position above the object opening 401 by longitudinal forward movement and then lower it to perform the slag cleaning operation at the drilling position. At the same time, after the slag cleaning of the drilling position is completed, it is convenient to move it to the position directly above the storage cylinder 304 by longitudinal backward movement and then perform the separation operation of the slag suction pump body 1 and the slag suction catheter 103.

[0021] See also Figure 1-Figure 5As shown, the longitudinal driving components 2 at both sides are combined and connected to form an assembly and disassembly component 3 for combining and disassembling the slag suction pump body 1 and the slag suction conduit 103, and the slag suction pump body 1 is coaxially located at the upper part of the assembly and disassembly component 3, and the slag suction conduit 103 is coaxially located at the lower part of the assembly and disassembly component 3, and at the same time, the inner periphery of the connecting pipe mouth 102 at the lower part of the slag suction pump body 1 can be coaxially threaded with the top periphery of the slag suction conduit 103. Specifically, the assembly and disassembly component 3 includes a restraining cylinder 302 and a storage cylinder 304, and connecting arms 301 are fixedly provided on both sides of the periphery of the restraining cylinder 302 along the transverse extension, and the connecting arms 301 are respectively and fixedly connected to the longitudinal driving components 2 at both sides, and the restraining cylinder 302 is open at the top and the bottom, and the slag suction pump body 1 is vertically The slag suction pipe 103 is placed in the storage cylinder 304 from top to bottom in a vertical sliding manner, and a motor seat 308 is provided below the bottom surface of the storage cylinder 304. The motor seat 308 is a U-shaped seat and the vertical parts on both sides are combined and connected with a lifting adjustment member 309 that can be vertically reciprocated and lifted. A driving motor 3011 is vertically fixed to the bottom surface of the horizontal part of the motor seat 308. The motor shaft 3010 at the top of the driving motor 3011 passes through the top surface of the motor seat 308 in a vertical sliding fit and the top end is coaxially fixed to the bottom surface of the storage tube 304. The reason for this arrangement is that the constraint tube 302 of the assembled disassembly component 3 is coaxially covered on the periphery of the slag suction pump body 1, so that the slag suction pump body 1 can be lifted from bottom to top, pass through the constraint tube 302 and be stably limited. At the same time, the outlet pipe 101 of the slag suction pump body 1 slides vertically from bottom to top along the limiting groove 303 until it supports the top of the limiting groove 303, so that the slag suction pump body 1 cannot move around. The suspended limit and anti-movement method of the slag suction pump body 1 is simple and easy to implement, and the storage tube 304 is driven to rotate positively and the lifting wings are driven by the driving motor 3011 The seat 3095 rises vertically along the support stud 3092 so that the slag suction guide tube 103 can be quickly combined with the connecting pipe mouth 102 by a forward twisting method, and the lifting wing seat 3095 is driven by the second motor 3011 to drive the storage tube 304 to rotate in the opposite direction and descend vertically along the support stud 3092 so that the slag suction guide tube 103 can be quickly separated from the connecting pipe mouth 102 by a reverse twisting method. The combination and separation of the slag suction guide tube 103 and the slag suction pump body 1 are simple and easy to achieve, and in the process of combining and disassembling the slag suction guide tube 103 and the slag suction pump body 1, the constraint tube 302 and the storage tube 304 work together. Specifically, in the process of the constraint tube 302 limiting the position of the slag suction pump body 1,The storage cylinder 304 will cooperate with the slag suction conduit 103 to rise and fall together to realize the combination and separation process of the slag suction conduit 103 and the slag suction pump body 1.

[0022] See also Figure 1-Figure 5 As shown, the assembly and disassembly component 3 and the longitudinal drive component 2 are optimized as follows. Specifically, with respect to the assembly and disassembly component 3, a plurality of radially arranged mounting holes 305 are provided on the periphery of the storage barrel 304, and the mounting holes 305 are all through holes and are coaxially interspersed with clamping studs 306 in a threaded manner. The inner ends of the clamping studs 306 are coaxially fixed with elastic clamping blocks 3012 whose outer diameter is smaller than the aperture of the mounting holes 305, and the outer ends of the clamping studs 306 are coaxially fixed with hand wheels 307. With such an arrangement, it is convenient to press the elastic clamping blocks 3012 against the outer bottom of the slag suction conduit 103 by twisting the clamping studs 306, so as to firmly and reliably coaxially fix the slag suction conduit 103 to the inner periphery of the storage barrel 304, thereby facilitating the slag suction conduit 103 to rotate with the storage barrel 304. More preferably, the lifting and lowering adjustment parts 309 include support studs 3092 and lifting wing seats 3095, support studs 3092 are vertically fixed on both sides of the rear part of the top surface of the base 4, lifting wing seats 3095 are horizontally fixed on the outer sides of the vertical parts on both sides of the motor seat 308, and the lifting wing seats 3095 on both sides are vertically opened at the outer sides away from each other. Matching holes 3096 are aligned coaxially one by one with the supporting studs 3092, and the supporting studs 3092 pass through the corresponding matching holes 3096 in a vertical sliding matching manner. With this arrangement, it is convenient to drive the motor shaft, the storage barrel 304 and the slag suction guide tube 103 to smoothly complete the lifting action by means of the matching holes 3096 of the lifting wing seats 3095 sliding vertically along the supporting studs 3092.

[0023] Optionally, the support stud 3092 is coaxially engaged with the limit nut 3094 at the upper and lower ends of the matching hole 3096, and the limit nut 3094 is a hand-tightened knurled nut, so that the lifting position height of the lifting wing seat 3095 can be limited by the setting of the limit nut 3094, which can ensure that the lifting wing seat 3095 does not rise to too high a height by the lifting wing seat 3095 against the limit nut 3094 at the top, and at the same time, the lifting wing seat 3095 is supported by the limit nut 3094 at the bottom to ensure that the lifting wing seat 3095 does not fall to too low a height. Further optionally, the outer end surfaces of the lifting wing seats 3095 at both sides that are away from each other are flatly installed with handles 3093 for easy holding, and the top of the support stud 3092 is coaxially and detachably combined with an anti-drop cap 3091. Such an arrangement makes it easy for the staff to lift the lifting wing seat 3095 vertically up or down by holding the handle 3093 and applying force, and at the same time, it is easy to prevent the lifting wing seat 3095 and the limiting nut 3094 from accidentally detaching from the top of the support stud 3092 by setting the anti-drop cap 3091. Specifically for the longitudinal drive assembly 2, the outer periphery of the guide rod 2010 is coaxially fixed with a limiting sleeve 208, and when the constraint cylinder 302 and the storage cylinder 304 are vertically coaxially opposite, the rear end face of the guide seat 209 contacts the front end face of the limiting sleeve 208. The purpose of this arrangement is that the constraint cylinder 302 can be limited and moved to be exactly coaxial with the storage cylinder 304 by the guide seat 209 pressing against the limiting sleeve 208, which further facilitates the combination and disassembly operation of the slag suction pump body 1 and the slag suction guide tube 103 after the constraint cylinder 302 and the storage cylinder 304 are coaxially aligned.

[0024] The above structure is adopted, specifically in the process of drilling and clearing slag from bored cast-in-place piles of bridges, because the assembly and disassembly component 3 is provided, the constraint tube 302 of the assembly and disassembly component 3 is coaxially covered on the periphery of the slag suction pump body 1, so that the slag suction pump body 1 can be lifted from bottom to top, pass through the constraint tube 302 and be stably limited. At the same time, the outlet pipe 101 of the slag suction pump body 1 slides vertically from bottom to top along the limiting groove 303 until it supports the top of the limiting groove 303, so that the slag suction pump body 1 can be restricted from moving around. The suspended limit and anti-movement method of the slag suction pump body 1 is simple and easy to implement, instead of the operation method of configuring personnel to hold it steady, ensuring that the slag suction pump body 1 can be combined with the slag suction guide tube 103 The slag suction tube 103 is connected to the slag suction pump body 1 by the lifting and lowering adjustment member 309 at the bottom, and the lifting and lowering adjustment member 309 at the bottom drives the motor seat 308 and the storage barrel 304 to rise, so that the slag suction tube 103 coaxially placed inside the storage barrel 304 is coaxially opposite to the connecting pipe mouth 102 of the slag suction pump body 1. At the same time, the storage barrel 304 is driven to rotate forward by the driving motor 2 3011 and the lifting wing seat 3095 is vertically raised along the support stud 3092, so that the slag suction tube 103 can be quickly combined with the connecting pipe mouth 102 by forward twisting, and the storage barrel 304 is driven to rotate in the opposite direction by the driving motor 2 3011 and the lifting wing seat 3095 is vertically raised along the support stud 3092. The vertical descending method can make the slag suction conduit 103 realize the rapid separation from the connecting pipe mouth 102 by reverse twisting. The combination and separation method of the slag suction conduit 103 and the slag suction pump body 1 is simple and easy to realize, replacing the operation method of staff auxiliary comparison and manual combination and separation, which is convenient to operate and is conducive to improving the slag cleaning efficiency of the drill hole. Since the driving motor 201 of the longitudinal driving component 2 drives the screw rod 204 to rotate, the constraint cylinder 302 and the slag suction pump body 1 can be driven to move longitudinally together. After the slag suction pump body 1 and the slag suction conduit 103 are combined, it is convenient to move the slag suction pump body 1 and the slag suction conduit 103 to the position at the object passing opening 40 by longitudinally moving forward. 1 and then lowered to carry out slag cleaning operation at the drilling position. At the same time, after the slag cleaning of the drilling position is completed, the slag suction pump body 1 and the slag suction guide tube 103 are moved longitudinally backward to be located just above the storage cylinder 304, and then the slag suction pump body 1 and the slag suction guide tube 103 are separated. Moreover, since the limiting sleeve 208 is coaxially fixed on the periphery of the guide rod 2010 of the longitudinal drive assembly 2, the limiting sleeve 208 can be pressed against the limiting sleeve 208 by the guide seat 209, so that the constraint cylinder 302 can be limited and moved to be exactly coaxial with the storage cylinder 304, which further facilitates the combination and separation operation of the slag suction pump body 1 and the slag suction guide tube 103 after the constraint cylinder 302 and the storage cylinder 304 are coaxially aligned.
