Description

Technical Field

[0001] The invention belongs to the technical field of underwater construction equipment, and in particular relates to an underwater hydraulic pick. Background Art

[0002] Underwater hydraulic pick is a construction tool used for underwater rock mining and crushing during underwater construction. It is mainly used for concrete, small rock crushing, coral reef demolition, piling, and tamping.

[0003] The underwater hydraulic picks in the prior art have some disadvantages: 1. Due to underwater construction, the hydraulic picks generate vibrations during operation, which will make the water turbid, thereby affecting the working line of sight, reducing work efficiency, and also posing certain safety hazards; 2. Since the user is operating underwater, the user cannot stabilize his body underwater, resulting in the user being unable to operate in the correct posture for a long time, which poses a safety hazard and reduces construction efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide an underwater hydraulic pick. A pick body and a protective frame are set, and the pick body is detachably connected to the front side of the opening of the protective frame through a connecting assembly. First, on the water, the user enters the protective frame and faces the opening, and then the pick body is connected to the front side of the opening through the connecting assembly. The lifting equipment puts the protective frame into the underwater construction site through the lifting ear. During the underwater working process of the pick body, the turbid water located in the front side of the opening is discharged to the rear side of the protective frame through the dust suction assembly, ensuring that the user's line of sight is not affected. At the same time, the protective frame can protect the user in the water and stabilize the user's body shape, ensuring that the user operates the pick body with the correct posture for a long time, eliminating safety hazards and improving processing efficiency.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An underwater hydraulic pickaxe comprises a pickaxe body and a protective frame, wherein a lifting lug is provided on the top of the protective frame, an opening is provided on one side of the protective frame, the pickaxe body is detachably connected to the front side of the opening via a connecting assembly, and a dust suction assembly is provided in the protective frame, which sucks dust from the front side of the opening and discharges it from the rear side of the protective frame. The present invention provides a pickaxe body and a protective frame, and detachably connects the pickaxe body to the front side of the opening of the protective frame via the connecting assembly. First, when the user is above water, he enters the protective frame and faces the opening. Then, the pickaxe body is connected to the front side of the opening via the connecting assembly. The lifting equipment lowers the protective frame into the underwater construction site via the lifting lug. During the underwater operation of the pickaxe body, the dust suction assembly discharges turbid water from the front side of the opening to the rear side of the protective frame, thereby ensuring that the user's vision is not affected. At the same time, the protective frame can protect the user in the water and stabilize the user's body shape, ensuring that the user can operate the pickaxe body in a correct posture for a long time, thereby eliminating safety hazards and improving processing efficiency.

[0007] Furthermore, the connection assembly includes a connecting belt and a connecting frame. One end of each connecting belt is connected to either side of the opening, and the connecting frame is fixedly connected to the pick body corresponding to the connecting belt. The other end of the connecting belt is plugged into the two ends of the connecting frame via a plug-in. By fixing one end of the connecting belt to the protective frame, installing the connecting frame on the pick body, and plugging the other end of the connecting belt into the two ends of the connecting frame via a plug-in, a detachable connection between the pick body and the protective frame is achieved.

[0008] Furthermore, the connector includes a socket and an insert block. The sockets are provided at both ends of the connecting frame. The insert block is fixedly connected to the other end of the connecting belt. The insert block is inserted into the socket to achieve the connection between the protective frame and the pick body. By inserting the insert block on the connecting belt into the socket, the protective frame and the pick body are detachably connected.

[0009] Furthermore, the socket is provided with a slot, and both ends of the slot are rotatably connected to a limit frame, the bottom of the limit frame is located on one side of the slot and is provided with a limit part 1, the top of the limit frame is located on one side of the slot and is provided with a limit part 2, the limit part 1 is located in the slot, and both ends of the plug block are provided with limit grooves corresponding to the limit part 2, the bottom of the plug block abuts against the top surface of the limit part 1, and the limit part 2 is inserted into the limit groove. When the plug block is inserted into the slot, the bottom of the plug block first abuts against the limit part 1, and the limit part 1 is controlled to swing into the slot, thereby controlling the limit part 2 on the limit frame to swing toward the plug block. When the plug block is inserted into the slot, the limit part 2 is clamped in the limit grooves on both sides of the plug block, thereby fixing the plug block to the socket; when it is necessary to separate the pick body from the protective frame, the limit frame is first controlled to swing toward both sides of the slot, so that the limit part 2 is disengaged from the limit groove, and at the same time, the limit part 1 swings upward, so that the limit part 1 pushes the plug block out of the slot, thereby achieving the separation between the protective frame and the pick body.

[0010] Furthermore, the dust collection assembly includes a conveying pipeline, a water suction pump and a drainage pump. The conveying pipeline is fixedly connected to the bottom surface of the protective frame. The conveying pipeline includes an inlet section, a branch section and an outlet section.

The two sides of the other end of the inlet section are respectively connected to one end of the branch section, and the other end of the branch section is connected to one end of the outlet section. The other end of the outlet section is the water outlet end. The drainage pump is connected to the branch section corresponding to the water outlet end. The water inlet end and the water outlet end are both provided with a filter. After the water suction pump and the drainage pump are in operation, the water inlet end absorbs the turbid water at the construction site of the pickaxe body, and cooperates with the drainage pump to suck the water from the water inlet end and discharge it from the water outlet end, which calmly ensures the user's sight underwater. The setting of the filter screen has a filtering effect on the water to prevent impurities from entering the conveying pipeline.

[0011] Furthermore, the conveying pipeline is fixedly connected to the protective frame through a fixing piece, and the fixing piece includes a fixing base and a clamping base. The three fixing bases are fixedly connected to the bottom surface of the protective frame in a herringbone shape, and the conveying pipeline is clamped between the three fixing bases. The bottom surface of the clamping base corresponds to the fixed base and is provided with a claw.

The arrangement of the adjusting groove one and the adjusting groove two realizes that the positions of the Z-shaped pressing frame one and the Z-shaped pressing frame two are adjustable, and can be adjusted according to the size of the conveying pipeline. After the adjustment is completed, the locking nut is tightened and fixed, and the pressing part one and the pressing part two are pressed on the conveying pipeline. At the same time, the arrangement of the plug-in groove and the plug-in block increases the contact area between the Z-shaped pressing frame one and the Z-shaped pressing frame two, thereby improving the connection stability between the Z-shaped pressing frame one and the Z-shaped pressing frame two.

[0013] Furthermore, the bottom surface of the protective frame is provided with a foot fixing assembly, which is used to fix the operator's feet. The bottom surface of the protective frame is provided with a slide groove. The foot fixing assembly includes a limiter and a slider. The slider is fixedly connected to the bottom of the limiter, and the slider is slidably connected within the slide groove. The provision of the foot fixing assembly has a fixing effect on the user's feet, preventing the user from being unstable due to the buoyancy of the water underwater, and ensuring the user's posture underwater.
