Description

Technical Field

[0001] This application relates to the field of underground foundation construction, and more specifically, to a drill rod clamping device for a twin-wheel agitator. Background Technology

[0002] The guide rod type double wheel stirring drill is equipped with two milling wheels driven by a waterproof gearbox at the bottom of the multi-section drill rod. The waterproof gearbox is connected to the drill rod through a special frame. After the lifting frame with clamping function clamps the drill rod, the lifting frame is moved up and down by the main winch, thereby causing the drill rod and the milling wheel fixed at the bottom to move down or up.

[0003] The utility model patent with authorization announcement number CN218293529U discloses a drill rod clamping device for a double-wheel stirring drill, including a frame, a front support, two sliding frames, two clamping cylinders, and a drill rod with multiple pairs of drill rod grooves. It has the effect of reducing the lateral bending moment generated during the drill rod clamping process and ensuring the safe operation of the double-wheel stirring drill.

[0004] In the above scheme, the drill rod works by drilling downwards through the milling wheel at its bottom. As a result, the drill rod enters the borehole. However, there is a lot of soil inside the borehole, which can easily accumulate in the grooves on the side wall of the drill rod. When the drill rod moves upwards, the hydraulic cylinder drives the sliding frame to move into the groove of the drill rod. This causes the sliding frame to be blocked by the soil in the groove of the drill rod, affecting the clamping effect on the drill rod. Therefore, we propose a drill rod clamping device for a double-wheel stirring drill. Utility Model Content

Detailed Implementation

[0020] The technical solution in this application embodiment is to solve the problem of soil remaining in the drill rod groove affecting clamping, and the overall idea is as follows:

[0021] Example:

[0022] Please see Figure 1-4 A drill rod clamping device for a dual-wheel agitator includes a base 10. The base 10 has a rectangular hole 20 for the drill rod of the dual-wheel agitator to pass through. Through holes 30 are formed on the side walls at both ends of the rectangular hole 20. A clamping mechanism 40 for fixing the drill rod is installed in each of the two through holes 30. A cavity 50 is formed inside the base 10, and a drill rod flushing mechanism 60 communicating with the cavity 50 is installed on its top. A pulley frame 140 is fixedly installed on the top of the base 10. Specifically, the drill rod of the dual-wheel agitator passes through the rectangular hole 20 and can be fixed by the clamping mechanisms 40 on both sides of the rectangular hole 20. Water can be stored in the cavity 50 inside the base 10, so that the drill rod flushing mechanism 60 can draw water from the cavity 50 to flush the grooves on the side walls of the drill rod. The soil in the grooves affects the clamping mechanism 40 to clamp and fix the drill rod.

[0023] See Figure 3 The clamping mechanism 40 includes a hydraulic cylinder 410 installed in the through hole 30. The output shaft of the hydraulic cylinder 410 is connected to a clamping block 420. The clamping block 420 is slidably disposed in the through hole 30. When set, the specific installation structure of the hydraulic cylinder 410 is the prior art. The hydraulic cylinder 410 drives the clamping block 420 to move so that the clamping block 420 moves into the groove of the drill rod side wall, thereby achieving clamping and fixing of the drill rod.

[0024] See Figure 1The drill pipe flushing mechanism 60 includes a water pump 610 installed on the top of the base 10. The inlet end of the water pump 610 is connected to a water pumping pipe 620, which is connected to the cavity 50. The outlet end of the water pump 610 is connected to a spraying mechanism 630, which is installed at the bottom of the base 10. In a specific configuration, the inlet end of the water pumping pipe 620 is located at the bottom of the cavity 50, so that the water pump 610 draws water from the cavity 50 through the water pumping pipe 620 and then delivers the water to the spraying mechanism 630, thereby flushing the grooves on the outer wall of the drill pipe.

[0025] See Figure 1-3 The spraying mechanism 630 includes two brackets 6310 fixedly installed at the bottom of the base 10. A diverter pipe 6320 is fixedly installed at one end of each bracket 6310. Both diverter pipes 6320 are connected to a water pump 610, and several nozzles 6330 are connected to the opposing side walls of each diverter pipe 6320. A water outlet pipe 70 is connected to the outlet end of the water pump 610, and the water outlet pipe 70 passes through the cavity 50. The two pipes are connected by the same U-shaped pipe 710. The water outlet pipe 70 is connected to the U-shaped pipe 710. It should be noted that the two branch pipes 6320 are set horizontally, and the nozzles 6330 on both sides are set facing each other. The water pump 610 delivers water to the U-shaped pipe 710 through the water outlet pipe 70, so that the water is divided from the U-shaped pipe 710 into the two branch pipes 6320, and finally sprayed out from the nozzles 6330 on both sides to wash the grooves on the side wall of the drill rod.

[0026] See Figure 3 Four positioning wheels 110 are fixedly installed at the bottom of the base 10. The four positioning wheels 110 are located around the rectangular hole 20 respectively. The nozzle 6330 is located below the positioning wheels 110. Specifically, the four positioning wheels 110 are respectively set to contact the four side walls of the drill rod to achieve the purpose of guiding and limiting the drill rod.

[0027] See Figure 1 A drain pipe 120 is installed on one side wall of the seat 10. The drain pipe 120 is connected to the cavity 50. A water inlet hole 130 is opened on the top of the seat 10. The water inlet hole 130 is connected to the top of the cavity 50. In a specific setting, a valve (not shown in the figure) is installed on the drain pipe 120 to control the opening and closing of the drain pipe 120. An existing cover plate can be placed on the water inlet hole 130 to block the water inlet hole 130.

[0028] When this application is used:

[0029] The drill rod passes through the rectangular hole 20 on the base 10. The drill rod is lifted upward by the hoisting device of the equipment, so that the groove on the side wall of the drill rod can be aligned with the clamping block 420. Then, the hydraulic cylinder 410 drives the clamping block 420 to move so that the clamping block 420 is inserted into the groove on the side wall of the drill rod to clamp and fix the drill rod. Before clamping and fixing the drill rod, the groove of the drill rod is moved to the nozzle 6330, and the water pump 610 is started. The water pump 610 draws water from the cavity 50 through the water pumping pipe 620, and then enters the U-shaped pipe 710 through the water outlet pipe 70, so that the water is distributed to the two diversion pipes 6320, and finally sprayed out from several nozzles 6330 to flush the groove on the side wall of the drill rod. After that, the drill rod is moved upward so that the groove on the side wall of the drill rod aligns with the clamping block 420.

[0030] It should be noted that the specific models and specifications of the hydraulic cylinder 410 and the water pump 610 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0031] The power supply and operating principle of the hydraulic cylinder 410 and the water pump 610 are clear to those skilled in the art and will not be described in detail here.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
