DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the embodiments:

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides an engineering geological drilling rig with a cleaning function, including a mobile base 1, a support 2 and a water storage device 3 in an inverted U shape arranged on the mobile base 1, a hydraulic drive device 4 arranged inside the support 2, a movable plate 5, a drilling rig body 6, a cleaning component 7, and a pumping device 8 arranged on the mobile base 1. The support 2 and the water storage device 3 are arranged at the front and rear ends of the mobile base 1 respectively, the upper end of the hydraulic drive device 4 is connected to the top plate of the support 2, and the lower end thereof is connected to the movable plate 5, the drilling rig body 6 is connected to the bottom of the movable plate 5, a cleaning component 7 is arranged below the drilling rig body 6, and the cleaning component 7 is connected to the inner walls of both sides of the support 2, and the pumping device 8 is arranged between the cleaning component 7 and the water storage device 3 and is respectively connected to the two through pipelines. The hydraulic drive device 4 connected to the movable plate 5 as a control mechanism can use a multi-stage hydraulic rod to provide a power source for the entire engineering geological drilling rig, and can also use other devices that can provide linear motion power. The pumping device 8 is connected to the movable plate 5 through a mechanical transmission mechanism to obtain the power required for pumping water. The mobile base 1 is provided with an opening extending vertically through one end of the cleaning component 7. The drilling rig body 6 can move up and down under the control of the hydraulic drive device 4 to pass through the cleaning component 7 and the opening respectively. The purpose of setting the opening is to facilitate the drilling rig body 6 to perform geological drilling operations.

[0034] During the cleaning operation, the water storage device 3, the hydraulic drive device 4, the drilling rig body 6, the cleaning component 7, the mechanical transmission mechanism and the pumping device 8 and other devices cooperate with each other. After the engineering geological drilling rig completes the geological drilling operation, the drilling rig body 6 can be automatically cleaned. The hydraulic drive device 4 can provide a power source to control the drilling rig body 6 to move up and down for drilling operations. At the same time, the power is transmitted to the pumping device 8 through the mechanical transmission mechanism so that the pumping device 8 extracts the water in the water storage device 3 and transports it to the cleaning component 7, so that the cleaning component cleans the drilling rig body that moves up and down inside it.

[0035] like Figure 2 As shown, the mechanical transmission mechanism includes a gear transmission device 9, a transmission shaft 10, a belt transmission device 11 and a crank 12. The gear transmission device 9 is arranged on one side of the hydraulic drive device 4 and connected to the movable plate 5. One end of the transmission shaft 10 is fixedly connected to the gear transmission device 9, and the other end thereof is rotatably connected to the inner wall of one side of the bracket 2 through a bearing. The crank 12 is arranged on the mobile base 1 through two support plates 121, and its two ends are respectively rotatably connected to the two support plates 121 through bearings. One end of the belt transmission device 11 is fixedly sleeved on the transmission shaft 10 and the other end is fixedly sleeved on one end of the crank 12. When the hydraulic drive device 4 is started, the drilling rig body 6 connected to the hydraulic drive device 4 through the movable plate 5 performs linear motion, and the gear transmission device 9 can convert the linear motion of the hydraulic drive device 4 into the rotational motion of the gear, and then convert the rotational motion of the gear into the linear reciprocating motion of the crank 12 through the transmission shaft 10 and the belt transmission device 11, thereby providing the pumping device 8 connected to the crank 12 with the power for pumping and conveying water.

[0036] like Figure 3 and Figure 5 As shown, the gear transmission device 9 includes a rack 91, a gear 92 and a round block 93. One end of the rack 91 is connected to the movable plate 5 and the other end passes through the top plate of the bracket 2. The gear 92 is meshed with the rack 91 and a ratchet groove 921 is provided at the center position of the gear 92. The round block 93 is arranged in the ratchet groove 921 and is fixedly connected to one end of the transmission shaft 10. A limiting component is provided near the outer periphery of the round block 93, and the limiting component is adapted to the shape and direction of the ratchet groove 921.

[0037] like Figure 5 and Figure 6As shown, the limiting component includes a baffle 931 fixedly arranged on one side of the round block 93 and a pawl 932 arranged opposite to the baffle 931, the baffle 931 is arranged perpendicular to the round surface of the round block 93, and the opposite sides of the baffle 931 and the pawl 932 are respectively hinged with mounting blocks, and a telescopic column 934 is fixedly connected between the two mounting blocks. A spring 933 is sleeved on the outside of the telescopic column 934, and the two ends of the spring 933 are respectively fixedly connected to the two mounting blocks, and the pawl 932 is rotatably connected to one side of the round block 93 through a rotating shaft, so that the pawl 932 can rotate a certain angle relative to the round block 93 under the action of the external force when subjected to external force, and can return to its original position when the external force is withdrawn.

[0038] Since the round block 93 is arranged in the ratchet groove 921, the ratchet pawl 932 is located inside the ratchet groove 921 and is adapted to the shape and direction of the ratchet groove 921. When the drilling rig body 6 descends to start the drilling operation, the rack 91 descends, and the gear 92 rotates along the direction of the ratchet groove 921. At this time, the gear 92 is rotatably connected with the round block 93, and the transmission shaft fixedly connected to the round block 93 is stationary, and the pumping device 8 does not provide water to the cleaning component 7; when the drilling rig body 6 rises to end the drilling operation, the rack 91 rises, and the gear 92 rotates along the ratchet groove 921. The gear 92 is connected with the ratchet pawl 932 on the round block 93 through the ratchet groove 921, and the transmission shaft 10 fixedly connected to the round block 93 rotates along with the gear 92, so that the pumping device 8 pumps water and supplies water to the cleaning assembly 7. The drilling rig body 6 in the rising process is cleaned when passing through the cleaning assembly 7, thereby achieving the purpose of automatically cleaning the drilling rig body 6, thereby reducing the labor intensity of the operator. At the same time, such a design further optimizes the cleaning function of the present application and is more energy-saving and environmentally friendly.

[0039] like Figure 4 As shown, the belt transmission device 11 includes a groove wheel 111 fixedly mounted on the end of the transmission shaft 10 away from the round block 93, a groove wheel 112 fixedly mounted on one end of the crank 12, and a transmission belt 113 mounted between the groove wheel 111 and the groove wheel 112.

[0040] The pumping device 8 includes a sleeve 81 sleeved in the middle of the crank 12, a piston cylinder 83 horizontally arranged on the mobile base 1 through the second support plate 82, and a connecting rod 85 connected to the sleeve 81 at one end. A piston plate 84 is also movably arranged inside the piston cylinder 83, and the other end of the connecting rod 85 is hinged to the piston plate 84. The second support plate 82 is vertically arranged on the mobile base 1, and the piston cylinder 83 is a horizontal cylindrical shape that penetrates and is arranged on the second support plate 82. The side wall of the piston cylinder 83 is connected to the water storage device 3 through a water inlet pipe 87 provided with a one-way valve, and the top of the piston cylinder 83, that is, the front end, is connected to the cleaning component 7 through a water outlet pipe 86. The interface between the water inlet pipe 87 and the side wall of the piston cylinder 83 is located between the piston plate 84 and the top of the piston cylinder 83, so that the piston plate 84, under the action of the linear reciprocating motion provided by the crank 12, draws the water in the water storage device 3 into the piston cylinder 83 through the water inlet pipe 87 and then squeezes and transports it to the cleaning component 7 through the water outlet pipe 86.

[0041] The cleaning assembly 7 includes an annular cleaning nozzle 71 connected to the water outlet pipe 86 for spraying water to clean the drilling rig body 6 . The annular cleaning nozzle 71 is connected to the inner walls on both sides of the bracket 2 through two connecting plates 72 .

[0042] The water storage device 3 comprises a water tank 31 provided with scale lines and arranged on the mobile base 1 , and a funnel 32 plugged into the top of the water tank 31 .

[0043] During operation, the hydraulic drive device 4 is started, and the drilling rig body 6 descends through the opening on the mobile base 1 to perform drilling operations. At this time, the annular cleaning nozzle 71 does not spray water for cleaning. After the drilling is completed, the drilling rig body 6 rises, and the annular cleaning nozzle 71 sprays water for cleaning during the rising process, thereby achieving a good automatic cleaning effect, reducing labor intensity, extending the service life of the drilling rig, and reducing maintenance costs.

[0044] Example 2

[0045] like Figure 7 As shown, the engineering geological drilling rig with a cleaning function provided in this embodiment has the same structure of each component and the connection relationship between the components as in Embodiment 1, except that:

[0046] A wiping assembly 13 is provided between the cleaning assembly 7 and the drilling rig body 6 . The wiping assembly 13 includes two split semicircular wiping components, two vertical plates 131 , two L-shaped plates 132 and two limiting bolts 133 .

[0047] Two split semicircular wiping components are arranged above the annular cleaning nozzle 71, and two vertical plates 131 are respectively arranged on two connecting plates 72. One end of the L-shaped plate 132 is movably penetrated on the vertical plate 131, and the other end thereof is fixedly connected to the semicircular wiping component. The L-shaped plate 132 can move horizontally on the vertical plate 131. The limiting bolt 133 is penetrated on the vertical plate 131 and is located below the L-shaped plate 132, thereby limiting the horizontal movement of the semicircular wiping component. The limiting bolt 133 is connected to the vertical plate 131 by a thread.

[0048] The semicircular wiping component includes an arc plate 134 and absorbent cotton 135 detachably arranged inside the arc plate 134. Specifically, the absorbent cotton 135 can be connected to the arc plate 134 via Velcro 136 or other detachable connecting parts.

[0049] During operation, the drill body 6 can pass through the cleaning assembly 7 and the wiping assembly 13 in sequence during the rising process, which can quickly dry the surface of the drill body 6, effectively prevent rust and corrosion on its outer surface, and further ensure the service life of the drill body 6. When the absorbent cotton 135 needs to be replaced, the two limit bolts 133 can be loosened, and the two arc plates 134 can be pulled out horizontally through the L-shaped plate 132 to separate them, so as to disassemble and replace the absorbent cotton 135. After the replacement is completed, the two limit bolts 133 are tightened to press the two arc plates 134 together, and then it can be used normally.
