Description

Technical Field

[0001] This utility model belongs to the technical field of mining drilling equipment, and in particular relates to a drilling fixing device for lead-zinc mining. Background Technology

[0002] Before lead-zinc mining, numerous blast holes need to be drilled in the ore rock, and explosives are then loaded into these holes to break the ore into pieces suitable for shoveling and transportation. During the drilling process, the drill rod is driven to rotate by a drilling rig, which drills holes in the lead-zinc ore rock. Due to its long length, the drill rod is prone to swaying and deviating during rotation, causing deviations in the drilling direction. Furthermore, manually holding the drill rod can cause hand injuries due to friction from the high-speed rotation of the drill rod.

[0003] To address these issues, we provide a drilling fixing device for lead-zinc mining to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling fixing device for lead-zinc mining. It involves interlocking the open ends of two V-shaped outer frame sleeves, and installing four ball bearing plates inside the two outer frame sleeves. A hemispherical ball bearing groove is formed on the side of the ball bearing plate away from the outer frame sleeve, where balls are rolled and installed. The drill rod is passed between the two outer frame sleeves, and the balls on the four ball bearing plates roll and contact the drill rod surface, clamping the drill rod with the balls on all four sides, thus preventing deviation during rotation. A support assembly is installed at the lower end of the outer frame sleeve, supporting the two outer frame sleeves at the required height. The support assembly supports the drill rod, allowing the drill rod to drill into the lead-zinc ore at the desired position, ensuring that the hole diameter does not deviate.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figures 1 to 5This utility model relates to a drilling and fixing device for lead-zinc mining, comprising a rolling assembly 1, a support assembly 2, and two outer frame sleeves 3. The rolling assembly 1 includes four ball bearing plates 101 and four ball bearing sleeves 102. The two V-shaped outer frame sleeves 3 are interlocked at their open ends. Four ball bearing plates 101 are arranged inside the two outer frame sleeves 3. A hemispherical ball groove 101a is formed on the side of the ball bearing plate 101 away from the outer frame sleeve 3. Ball bearings 101b are rolled and installed in the ball groove 101a. The drill rod passes between the two outer frame sleeves 3, and the balls 101b on the four ball bearing plates 101 roll into contact with the drill rod surface, so that the drill rod is clamped by the balls 101b on all four sides, thereby preventing the drill rod from deviating during rotation; by setting a support component 2 at the lower end of the lower outer frame sleeve 3, the support component 2 supports the two outer frame sleeves 3 at the required height, and the support component 2 supports the drill rod, so that the drill rod drills into the lead-zinc ore rock at the required position, ensuring that the hole diameter direction does not deviate.

[0026] Specifically, the outer frame 3 is a V-shaped plate frame structure with an included angle of 90 degrees. The two outer frame sleeves 3 are vertically interlocked with each other. Four ball bearing plates 101 are respectively set on the inner side plate surface of the two outer frame sleeves 3. A set of hemispherical ball bearing grooves 101a are arranged along the length direction of the ball bearing plate 101 on the side plate surface away from the outer frame sleeve 3. Ball bearings 101b are rolled in the ball bearing grooves 101a. The ball bearing sleeve 102 is sleeved on the outer side of the ball bearing 101b mounting surface of the ball bearing plate 101. The ball bearings 101b penetrate the plate surface of the ball bearing sleeve 102. The support component 2 is set on the lower end surface of the outer frame sleeve 3.

[0027] Furthermore, adjusting screws 301 are threaded through and screwed onto the two side plates of the outer frame sleeve 3. One end of the adjusting screw 301 is connected to the ball plate 101 for transmission. Rotating the adjusting screw 301 causes the ball plate 101 to move inside the outer frame sleeve 3, so that the balls 101b on one side of the ball plate 101 can clamp drill rods of different sizes.

[0028] Furthermore, a sleeve 101c is fitted onto the side of the ball plate 101 away from the ball groove 101a. A set of damping springs 101c-1 are fixedly connected in an array along the length of the sleeve 101c on the side of the sleeve 101c closest to the ball plate 101. One end of the damping spring 101c-1 away from the sleeve 101c is fixedly connected to the surface of the ball plate 101. An adjusting screw 301 is rotatably mounted on the surface of the sleeve 101c through one end of the outer frame sleeve 3.

[0029] Furthermore, a set of guide rods 101c-2 are fixedly connected to the side of the sleeve 101c away from the ball plate 101. The guide rods 101c-2 slide through the surface of the outer frame sleeve 3. When the adjusting screw 301 drives the ball plate 101 to move, the guide rods 101c-2 make the movement of the ball plate 101 smooth and prevent the ball plate 101 from rotating.

[0030] Furthermore, connecting ears 302 are fixedly provided on the side surfaces of the outer frame sleeve 3 that extend away from the opening end. The two connecting ears 302 on the upper and lower outer frame sleeves 3 fit together. A set of connecting bolts 302a are threaded through the connecting ears 302 on the upper and lower outer frame sleeves 3. The drill rod is placed on the upper end of the lower outer frame sleeve 3, and the other outer frame sleeve 3 is fastened to the upper end of the lower outer frame sleeve 3, so that the connecting ears 302 on both sides of the upper outer frame sleeve 3 fit together with the connecting ears 302 on both sides of the lower outer frame sleeve 3. The connecting bolts 302a are used to fix the upper and lower connecting ears 302.

[0031] The operation process in this embodiment is as follows:

[0032] Place the drill rod on the upper end of the lower outer frame sleeve 3, and fasten the other outer frame sleeve 3 onto the upper end of the lower outer frame sleeve 3, so that the connecting ears 302 on both sides of the upper outer frame sleeve 3 are in contact with the connecting ears 302 on both sides of the lower outer frame sleeve 3, and fix the upper and lower connecting ears 302 with the connecting bolts 302a; rotate the adjusting screw 301 to push the plate sleeve 101c to move, thereby causing the shock-absorbing spring 101c-1 inside the plate sleeve 101c to push the ball plate. 101, so that the balls 101b on one side of the ball plate 101 are in contact with the surface of the drill rod, and the drill rod is clamped by the balls 101b on the four ball plates 101; when the drill rod rotates and moves forward, the balls 101b and the drill rod rotate and rub against each other, reducing the frictional force of the drill rod contact. The slight vibration generated when the drill rod rotates causes the ball plate 101 to vibrate. The vibration of the ball plate 101 is absorbed and buffered by the shock-absorbing spring 101c-1, thereby preventing the support assembly 2 from loosening under the action of vibration. Example 2

[0033] Please see Figures 1 to 5 Based on embodiment 1, the support assembly 2 includes an inner sleeve rod 201 and an outer sleeve tube 202. By threading the inner sleeve rod 201 into the outer sleeve tube 202, the upper end of the inner sleeve rod 201 is fixedly connected to the lower end of the outer frame sleeve 3. Rotating the inner sleeve rod 201 causes the inner sleeve rod 201 to extend or retract, thereby controlling the support height of the support assembly 2.

[0034] Specifically, a bottom support frame 201a is fixedly installed on the upper end face of the inner sleeve rod 201, and the upper end face of the bottom support frame 201a is fixedly installed on the lower end face of the lower outer frame sleeve 3. The inner sleeve rod 201 is threaded into the outer sleeve tube 202.

[0035] Furthermore, a bottom support plate 202a is fixedly installed at the lower end of the outer tube 202, and a set of anchor nails 202a-1 are threaded through the plate surface of the bottom support plate 202a.

[0036] The operation process in this embodiment is as follows:

[0037] Place the bottom support plate 202a on the surface of the rock, drive the anchor nail 202a-1 into the rock to fix it, and rotate the inner sleeve rod 201 to extend or retract the inner sleeve rod 201, thereby controlling the support height of the support component 2.
