Description

Technical Field

[0001] This utility model relates to the field of mining blasting technology, and in particular to a clamp for treating blast hole blockage. Background Technology

[0002] Mining blasting is an important method for separating ore from surrounding rock during mining. During mining blasting, a drilling machine is used to drill holes in the rock or ore, and explosives are loaded into the blast holes. The huge energy generated by the explosion is used to separate and break the rock or ore. However, during the drilling process, the rock at the hole opening is relatively broken. After drilling is completed, some of the broken rocks can easily fall into the hole, causing blockage and making it impossible to load explosives.

[0003] Therefore, the existing technology still needs further improvement and enhancement. Utility Model Content

[0004] The purpose of this utility model is to provide a clamp for dealing with blast hole blockage, thereby solving the technical problem of easy blockage of blast holes during mining blasting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamp for treating borehole blockage includes a barrel-shaped rod with a clamping mechanism at its bottom end. The clamping mechanism includes two symmetrically distributed irregularly shaped clamping plates, both of which are arc-shaped and arranged opposite each other to form a clamping space. The two irregularly shaped clamping plates are movably connected by a connecting rod assembly. The bottom ends of the irregularly shaped clamping plates are rounded. A column is fixedly connected to the top of each of the two irregularly shaped clamping plates. A hinge plate is provided between the columns, and the two hinge plates are hinged to each other. One of the columns is sleeved on the bottom end of the barrel-shaped rod. A sliding assembly is provided inside the barrel-shaped rod, and a control mechanism is provided at the top of the barrel-shaped rod. The control mechanism is connected to the sliding assembly, and the sliding assembly is connected to the connecting rod assembly.

[0007] Preferably, the sliding assembly includes a sliding sleeve and a sliding rod, the sliding sleeve being fixedly connected to the middle of the barrel rod, the sliding sleeve being slidably connected to the sliding rod, and the sliding rod being connected to the connecting rod assembly.

[0008] Preferably, the connecting rod assembly includes a connecting rod and a hinge lug, with both ends of the connecting rod hinged to the hinge lug and the slide rod respectively, and the hinge lug fixed to an irregular clamp plate away from the barrel rod.

[0009] Preferably, the control mechanism includes a slide groove, a slide column, and a movable handle. The slide groove is formed at the top of the barrel rod. The slide column is slidably connected to the slide groove. One end of the slide column is fixedly connected to the top of the slide rod, and the other end of the slide column is fixedly connected to the movable handle. A reset component is provided at the top of the slide rod.

[0010] Preferably, the reset assembly includes a directional post and a helical spring. The top end of the directional post is fixedly connected to the barrel rod, and the bottom end of the directional post is slidably connected to the top end of the slide rod. The helical spring is sleeved on the directional post, and the two ends of the helical spring are respectively connected to the slide rod and the barrel rod.

[0011] Preferably, a fixed handle is fixedly connected to the top of the barrel rod, and the fixed handle and the movable handle are located on the same side.

[0012] This invention involves inserting irregularly shaped clamping plates into the rock on both sides inside the blast hole. By pulling the movable handle close to the fixed handle with one hand, the movable handle moves the sliding rod upward via a sliding column, which in turn pulls the connecting rod to tilt, causing the hinged ears to approach the sliding rod and thus bringing the two irregularly shaped clamping plates closer together to clamp the obstructing rock. As the device is lifted, it is easily pulled out of the hole, preventing the rock from clogging the blast hole. Moreover, this invention has a simple structure and is easy to operate.

Therefore, they should not be construed as limitations on this utility model.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-4 As shown, a clamp for treating borehole blockage includes a barrel-shaped rod 1. The bottom end of the barrel-shaped rod 1 is equipped with a clamping mechanism, which includes two symmetrically distributed irregularly shaped clamping plates 21. Both irregularly shaped clamping plates 21 are arc-shaped and arranged opposite each other to form a clamping space. The two irregularly shaped clamping plates 21 are movably connected by a connecting rod assembly. Their bottom ends are rounded, and the horizontal projection formed by the two irregularly shaped clamping plates 21 is smaller than the borehole diameter. A column 22 is fixedly connected to the top of each of the two irregularly shaped clamping plates 21. A hinge plate 23 is provided between the columns 22, and the two hinge plates 23 are hinged together. One column 22 is fitted onto the bottom end of the barrel-shaped rod 1. A sliding assembly is provided inside the barrel-shaped rod 1, and a control mechanism is provided at the top of the barrel-shaped rod 1. The control mechanism is connected to the sliding assembly, and the sliding assembly is connected to the connecting rod assembly.

[0024] The column 22 is used to connect the irregular clamping plate 21 and the hinge plate 23. The hinge plate 23 maintains the movable connection of the column 22, so that the irregular clamping plate 21 can generate a clamping movement. Under the action of the control mechanism and the linkage assembly, the two move closer to each other to form a clamping action.

[0025] The sliding assembly includes a sliding sleeve 24 and a sliding rod 27. The sliding sleeve 24 is fixedly connected to the middle of the barrel rod 1, and the sliding sleeve 24 is slidably connected to the sliding rod 27. The sliding rod 27 is connected to the connecting rod assembly. The connecting rod assembly includes a connecting rod 25 and a hinge lug 26. The two ends of the connecting rod 25 are hinged to the hinge lug 26 and the sliding rod 27 respectively. The hinge lug 26 is fixed to the irregular clamping plate 21 away from the barrel rod 1.

[0026] In practical implementation, the sliding sleeve 24 is slidably connected to the sliding rod 27. When the sliding rod 27 moves upward, it pulls the connecting rod 25 to move. When one end of the connecting rod 25 moves upward, it pulls the other end and the irregularly shaped clamping plate 21 on the other side of the hinge lug 26, which can clamp the rock in the blast hole and lift it out of the hole along with the clamp. This structure can adapt to the small space of the blast hole and is simple and convenient to operate.

[0027] The control mechanism of this embodiment includes a slide groove 31, a slide column 32, and a movable handle 33. The slide groove 31 is formed at the top of the barrel rod 1. The slide column 32 is slidably connected to the slide groove 31. One end of the slide column 32 is fixedly connected to the top of the slide rod 27, and the other end of the slide column 32 is fixedly connected to the movable handle 33. A reset component is provided at the top of the slide rod 27. The slide groove 31 is used to slidably connect the slide column 32, and the slide column 32 is used to connect the movable handle 33. Manually pushing the movable handle 33 upward will cause the slide rod 27 to move upward.

[0028] In a preferred embodiment, the reset assembly includes a directional post 34 and a helical spring 35. The top end of the directional post 34 is fixedly connected to the barrel rod 1, and the bottom end of the directional post 34 is slidably connected to the top end of the slide rod 27. The helical spring 35 is sleeved on the directional post 34, and its two ends are fixedly connected to the slide rod 27 and the barrel rod 1, respectively. The directional post 34 is used to prevent the helical spring 35 from bending further, and the helical spring 35 uses its own elasticity to reset the slide rod 27.

[0029] For ease of operation, a fixed handle 4 is fixedly connected to the top of the barrel rod 1 in this embodiment. The fixed handle 4 and the movable handle 33 are located on the same side. The fixed handle 4 cooperates with the movable handle 33, and a clamping action is generated when the movable handle 33 moves closer to the fixed handle 4.

[0030] The working principle of the fixture provided in this application is described in detail below.

[0031] In practice, the movable handle 33 is held close to the fixed handle 4, causing the sliding column 32 to slide in the sliding groove 31. This drives the sliding sleeve 24 and the sliding rod 27 to move upward in sequence. The sliding rod 27 drives one end of the connecting rod 25 to move upward, which pulls the other end and the hinge ear 26 close to the irregular clamping plate 21 on the other side. Since the column 22 connected to the irregular clamping plate 21 is provided with a hinge plate 23, when the sliding rod 27 pulls the connecting rod 25, the hinge plate 23 maintains the movable connection of the column 22, so that the irregular clamping plate 21 can generate a clamping movement, which can clamp the rock in the blast hole and lift it out of the hole with the clamp.

[0032] After the rock is removed from the blast hole, the movable handle 33 is released. Due to the elasticity of the helical spring 35, the slide rod 27 is pushed downward to reset. The slide rod 27 pushes the connecting rod 25 downward, and the connecting rod 25 releases the two irregular clamping plates 21, thus releasing the rock from between the two irregular clamping plates 21. This completes the removal and placement of the rock in the blast hole, preventing the blast hole from becoming blocked.

[0033] Because the clamp in this embodiment adopts a rod-shaped structure and effectively utilizes the hinge mechanism, it is fully adaptable to the limited working space of the blast hole, and the structure is simple and easy to operate.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
