[0002] Ma Cheng Iron Mine employs the staged open-pit followed by backfilling mining method. A crucial step in ore mining is drilling, and Ma Cheng Iron Mine uses the E70-ITH large-diameter drilling rig for drilling operations.

[0003] When the first drill rod is completed in the blast hole, a protective pipe needs to be lowered into the blast hole to prevent damage to the hole opening and the falling of slag into the hole due to the drilling process.

[0004] Through on-site work, it was found that accidents frequently occurred during the lowering of the borehole casing, where the rock drilling rig would crush the arms of the personnel lowering the casing. Utility Model Content

[0005] This application aims to at least partially address the technical problem that the arms of personnel lowering the protective tube are easily injured during the lowering process. To this end, this application provides a protective tube clamp.

[0006] This application provides a hole-protecting pipe clamp, comprising:

[0007] First clamping component;

[0008] The second clamping member has one end rotatably connected to one end of the first clamping member;

[0009] The handle is fixedly connected to the second clamping member;

[0010] A traction rope, one end of which is fixedly connected to the first clamping member, rotates towards the second clamping member under the drive of the traction rope, and together with the second clamping member to form a clamping cavity for clamping the protective tube.

[0011] In some embodiments, both the first clamping member and the second clamping member are semi-circular, and the clamping cavity is circular.

[0012] In some embodiments, the protective tube clamp further includes a plurality of second rings, which are spaced apart and connected to the second clamping member along the circumference of the second clamping member; the second rings have first mounting holes, and the traction ropes are sequentially passed through each of the first mounting holes.

[0013] In some embodiments, the protective tube clamp further includes a plurality of first rings, which are spaced apart and connected to the first clamping member along the circumference of the first clamping member. Each first ring has a second mounting hole, and the traction rope is sequentially passed through each of the second mounting holes.

[0014] In some embodiments, both the first ring and the second ring are disposed outside the clamping cavity.

[0015] In some embodiments, the traction rope is fixedly connected to one end of the first clamping member and the second clamping member that are rotatably connected.

[0016] In some embodiments, the handle has an installation channel and a first through hole and a second through hole communicating with the installation channel; the first through hole is located on the side of the handle near the second clamping member, and one end of the traction rope connected to the first clamping member passes through the first through hole; the second through hole is located on the side of the handle away from the second clamping member, the traction rope is located in the installation channel, and the other end of the traction rope passes through the second through hole.

[0017] In some embodiments, the protective tube clamp further includes a pulling member, which is fixedly connected to the other end of the traction rope.

[0018] In some embodiments, the hole protector clamp further includes a reset member, which acts on the first clamping member and the second clamping member to drive the first clamping member to rotate away from the second clamping member when the traction rope is slack.

[0019] In some embodiments, the reset member is a torsion spring, which is disposed at one end where the first clamping member and the second clamping member are rotatably connected.

[0020] This utility model has at least the following beneficial effects:

[0021] This design allows the operator to hold the handle away from the second clamping member with their left hand, place the first and second clamping members over the borehole casing, and then pull the traction rope with their right hand to clamp the casing. The operator then moves the casing to align it with the blast hole. Once aligned, the operator releases the traction rope, allowing the casing to fall into the blast hole under gravity. During the deployment of the casing, the operator's arms are kept away from both the casing and the drilling rig. Even if the drilling rig malfunctions, it is less likely to injure the operator's arms, thus reducing the risk of being crushed by the rig and protecting the operator. Attached Figure Description

[0032] In related technologies, when the drilling rig rotates after drilling, the protective pipe 200 is lowered by hand, which poses a technical problem that the operator's arm is easily crushed by the drilling rig. This application provides a protective pipe clamp 100, which can at least partially solve the technical problem of easy arm injury for the operator lowering the protective pipe 200.

[0033] This application is described below with reference to the accompanying drawings and specific embodiments:

[0034] like Figure 1 and Figure 2 As shown, the hole protector 100 includes a first clamping member 110, a second clamping member 120, a handle 130, and a traction rope 140. One end of the second clamping member 120 is rotatably connected to one end of the first clamping member 110. The handle 130 is fixedly connected to the second clamping member 120. One end of the traction rope 140 is fixedly connected to the first clamping member 110. Driven by the traction rope 140, the first clamping member 110 rotates towards the second clamping member 120 and forms a clamping cavity 100a for clamping the hole protector 200.

[0035] The handle 130 is fixedly connected to the second clamping member 120. The fixing method can be varied, such as welding, bonding, or bolting. When using the hole-protecting tube clamp 100, the operator can control the position of the first clamping member 110 and the second clamping member 120 by holding the handle 130. The first clamping member 110 and the second clamping member 120 together form a clamping cavity 100a, within which the hole-protecting tube 200 is located and clamped by the first clamping member 110 and the second clamping member 120. One end of the traction rope 140 is fixed to the first clamping member 110. Tightening the traction rope 140 causes the first clamping member 110 to rotate towards the second clamping member 120, thereby clamping the hole-protecting tube 200. The rotational connection method between the first clamping member 110 and the second clamping member 120 is varied and is not limited in this application.

[0036] With this design, the operator can hold the handle 130 with their left hand, away from the second clamping member 120, and place the first clamping member 110 and the second clamping member 120 over the borehole protector 200. Then, the operator can pull the traction rope 140 with their right hand to clamp the borehole protector 200. Next, the operator can move the borehole protector 200 to align it with the blast hole 300. Once aligned, the operator can release the traction rope 140, and the borehole protector 200 will fall into the blast hole 300 under gravity. During the deployment of the borehole protector 200, the operator's arms are kept away from both the borehole protector 200 and the drilling rig. Even if the drilling rig malfunctions, it is less likely to injure the operator's arms, thus reducing the risk of the operator being crushed by the rig and protecting the operator.

[0037] The shape of the clamping cavity 100a is not limited in this application, and can be adapted to the shape of the protective tube 200, and can be rectangular, elliptical, etc.

[0038] In some embodiments, both the first clamping member 110 and the second clamping member 120 are semi-circular, and the clamping cavity 100a is circular. In these embodiments, the protective tube 200 is cylindrical. Setting the clamping cavity 100a as circular helps to increase the contact area between the first clamping member 110 and the second clamping member 120 and the outer wall of the protective tube 200, thereby increasing the clamping force of the first clamping member 110 and the second clamping member 120 on the protective tube 200, as well as increasing the friction between the first clamping member 110 and the protective tube 200 and the second clamping member 120, ensuring that the protective tube 200 will not fall uncontrollably during the clamping and moving process, thus improving the safety of the tube insertion operation.

[0039] In some embodiments, rubber pads are provided on the surfaces of the first clamping member 110 and the protective tube 200 that contact each other, as well as on the surfaces of the second clamping member 120 and the protective tube 200. The rubber pads prevent the first and second clamping members 110 and 120 from scratching the surface of the protective tube 200, and also help increase the friction between the first clamping member 110 and the protective tube 200, and between the second clamping member 120 and the protective tube 200, thereby improving the stability of the protective tube clamp 100.

[0040] In some embodiments, the protective tube clamp 100 further includes a plurality of second rings 150, which are spaced apart and connected to the second clamping member 120 along the circumference of the second clamping member 120. Each second ring 150 has a first mounting hole 100b, and a traction rope 140 is sequentially threaded through each of the first mounting holes 100b. The sequential threading of the traction rope 140 through each of the first mounting holes 100b helps to ensure that the traction rope 140 is arranged along the circumference of the second clamping member 120 and attached to the second clamping member 120, preventing the traction rope 140 from being located within the clamping cavity 100a and interfering with the clamping of the protective tube 200.

[0041] In some embodiments, the protective tube clamp 100 further includes a plurality of first rings 160, which are spaced apart and connected to the first clamping member 110 along the circumference of the first clamping member 110. Each first ring 160 has a second mounting hole 100c, and a traction rope 140 is sequentially passed through each of the second mounting holes 100c. The sequential passing of the traction rope 140 through each of the second mounting holes 100c helps to arrange the traction rope 140 along the circumference of the first clamping member 110 and attach it to the first clamping member 110, thus preventing the traction rope 140 from being located in the mounting cavity and interfering with the clamping of the protective tube 200.

[0042] In some embodiments, the first ring 160 is welded to the first clamping member 110, and the second ring 150 is welded to the second clamping member 120.

[0043] In some embodiments, the first ring 160 and the second ring 150 are both disposed outside the clamping cavity 100a to avoid the first ring 160 and the second ring 150 from contacting the protective tube 200 and affecting the clamping stability of the first clamping member 110 and the second clamping member 120.

[0044] The traction rope 140 can be fixedly connected to the end of the first clamping member 110 away from the end rotatably connected to the second clamping member 120, that is... Figure 2 The right end of the middle. In some embodiments, the traction rope 140 is fixedly connected to the end where the first clamping member 110 and the second clamping member 120 are rotatably connected. For example Figure 1 As shown, it is fixed to the left end of the first clamping member 110. The traction rope 140 is fixedly connected to the end of the first clamping member 110 and the second clamping member 120 that are rotatably connected. This allows the traction rope 140 to apply forces to multiple points of the first clamping member 110 when the traction rope 140 is pulled, causing the first clamping member 110 to rotate toward the side closer to the second clamping member 120. The force on the first clamping member 110 is more even, which helps to reduce the deformation of the first clamping member 110 due to uneven force.

[0045] In some embodiments, the handle 130 has an installation channel 100d and a first through hole 100e and a second through hole 100f communicating with the installation channel 100d. The first through hole 100e is located on the side of the handle 130 near the second clamping member 120, and one end of the traction rope 140 connected to the first clamping member 110 passes through the first through hole 100e. The second through hole 100f is located on the side of the handle 130 away from the second clamping member 120, and the traction rope 140 is located inside the installation channel 100d, with the other end of the traction rope 140 passing through the second through hole 100f. With this design, the middle area of ​​the traction rope 140 is located inside the handle 130 and is covered by the handle 130, with only the two sides of the traction rope 140 exposed, resulting in a cleaner appearance for the protective tube clamp 100. Furthermore, the central area of ​​the traction rope 140 is located within the handle 130, which allows the handle 130 to provide protection for the central area of ​​the traction rope 140 and extend the service life of the traction rope 140.

[0046] In some embodiments, such as Figure 1 As shown, the upper end of the handle 130 and the second clamping member 120 are welded together.

[0047] In some embodiments, the protective tube clamp 100 further includes a pulling member 170, which is fixedly connected to the other end of the traction rope 140. The traction rope 140 is relatively thin; if a user pulls on it, they are easily scratched, and it is difficult to apply force to the rope. The design of the pulling member 170 allows the user to grip and apply force to it, causing the first clamping member 110 to rotate towards the second clamping member 120, thus facilitating the user's pulling of the first clamping member 110.

[0048] In some embodiments, the pull member 170 is bonded to the traction rope 140. The pull member 170 is made of rubber and is relatively soft. The pull member 170 is provided with a hand hole 170a, which allows the operator's fingers to be inserted into the hand hole 170a, further facilitating the user to pull the first clamping member 110.

[0049] In some embodiments, the protective tube clamp 100 further includes a reset member 180, which acts on the first clamping member 110 and the second clamping member 120, and is used to rotate the first clamping member 110 away from the second clamping member 120 when the traction rope 140 is slack. One end of the reset member 180 acts on the first clamping member 110 and the other end acts on the second clamping member 120. The reset member 180 is used to rotate the first clamping member 110 when the traction rope 140 is not traction, so that the right end of the first clamping member 110 is away from the right end of the second clamping member 120, so as to facilitate the first clamping member 110 and the second clamping member 120 to be sleeved on the outside of the protective tube 200.

[0050] The reset element 180 can be an elastic part such as a rubber block or a spring, and is not limited thereto in this application. In some embodiments, the reset element 180 is a torsion spring, which is disposed at the end where the first clamping member 110 and the second clamping member 120 are rotatably connected. Figure 1 As shown, a torsion spring is disposed at the left end of the first clamping member 110. One end of the torsion spring is fixedly connected to the left end of the first clamping member 110, and the other end of the torsion spring is fixedly connected to the left end of the second clamping member 120. When the traction rope 140 pulls the first clamping member 110 closer to the second clamping member 120, the torsion spring torsional deformation and stores force. After the traction rope 140 is released, the torsion spring returns to its original deformation, causing the first clamping member 110 to move away from the second clamping member 120.

[0051] The working principle of the hole protector clamp 100 is described below:

[0052] like Figure 3 As shown, the operator holds the handle 130 with their left hand away from the second clamping member 120. After the first clamping member 110 and the second clamping member 120 are placed on the outside of the borehole tube 200, the operator pulls the traction rope 140 with their right hand, causing the first clamping member 110 to move closer to the second clamping member 120, so that the borehole tube 200 is clamped by the first clamping member 110 and the second clamping member 120. Then, the operator moves the borehole tube 200 to align it with the blast hole 300. After aligning with the blast hole 300, the operator releases the traction rope 140 with their right hand. The first clamping member 110 will move away from the second clamping member 120 under the action of the torsion spring. The first clamping member 110 and the second clamping member 120 release the borehole tube 200, and the borehole tube 200 will fall into the blast hole 300 under the action of gravity.
