Description

Technical Field

[0001] This application relates to the field of material cutting technology, and in particular to a wire saw guide device for raw material mining. Background Technology

[0002] In the mining of raw blocks, wire saws are used to cut the blocks. Traditional wire saws consist of a power chamber, a power unit, a drive wheel, a cutting rope, and a guide device. During operation, the power unit drives the drive wheel to rotate. The cutting rope is fitted onto the outside of the drive wheel, and the outer surface of the cutting surface is equipped with a high-hardness metal alloy cutting block. The outer surface of the drive wheel also has grooves for the metal alloy cutting block. This ensures that the drive wheel stably drives the cutting rope to rotate. The rotating cutting rope rubs against the surface of the raw block, and since the metal alloy cutting block is harder than the raw block, it cuts the block. During the cutting process, the guide device stabilizes the direction of the cutting rope's movement and prevents the cutting rope from detaching. Although existing wire saw guide devices for raw block mining have many advantages, they still have certain limitations in practical applications. Because the guide device lacks tension for the cutting rope, the rope may drag on the ground, and the friction between the cutting rope and the raw block may be insufficient, affecting cutting efficiency. Therefore, this application proposes a wire saw guide device for raw block mining to address these problems. Summary of the Invention

[0003] This application proposes a guide device for a wire saw used in raw material mining, which has the advantage of being able to adjust the tension of the cutting rope, thereby solving the problems of low cutting efficiency and dragging on the ground in traditional equipment.

[0004] To achieve the above objectives, this application adopts the following technical solution: a guide device for a wire saw used in raw block mining, comprising a base plate, a power chamber and a connecting rib plate fixedly installed on the top of the base plate, a power motor disposed on the front of the power chamber near the top, a power shaft fixedly installed at one end of the output shaft of the power motor, a sliding bushing disposed on the outer surface of the power shaft, a threaded rod disposed at one end of the power shaft, a transmission wheel disposed at one end of the threaded rod, a telescopic rod disposed on the front of the power chamber below the power motor, a locking block fixedly installed at one end of the output shaft of the telescopic rod, a protrusion disposed on the front of the locking block, a rotating device movably mounted on the outer surface of the sliding bushing, a cutting rope movably sleeved on the outer surface of the rotating device, a travel device disposed on the front of the power chamber below the telescopic rod, and a guide device fixedly installed on the top of the connecting rib plate.

[0005] Furthermore, the rotating device includes a shaft ring, a drive wheel is fixedly sleeved on the outer surface of the shaft ring, a sliding bearing is provided on the inner ring of the shaft ring, an internal threaded bushing is fixedly installed on the right side of the shaft ring, and a transmission spring is provided on the outer surface of the internal threaded bushing on the right side of the shaft ring. Specifically, the inner ring of the internal threaded bushing is provided with a thread near the right end and is engaged with the outer surface of the threaded rod. One end of the transmission spring is connected to the transmission wheel. The torque output by the power machine is transmitted to the drive wheel through the transmission wheel and the transmission spring. The outer surface of the drive wheel is wrapped with a cutting rope, and the cutting rope contacts the raw material and generates a large friction force, thereby creating a torque difference between the transmission wheel and the drive wheel, which acts on the transmission spring, causing the transmission spring to twist. Specifically, the front of the drive wheel is provided with a locking groove, and the locking grooves are distributed in a circular array. Before the device is in operation, the telescopic rod is in a retracted state, and the protrusion on the front of the locking block is separated from the locking groove. When the power unit is in operation, the telescopic rod is reset and drives the drive wheel to the initial position.

[0006] Furthermore, the travel device includes a slide rod, one end of which is fixedly mounted with a connecting seat, and the top of the connecting seat is fixedly mounted with a first contact seat. The outer surface of the slide rod has a sliding groove, and a sliding sleeve is movably mounted through the sliding groove. The top of the sliding sleeve is fixedly mounted with a second contact seat, and the bottom of both the connecting seat and the sliding sleeve is fixedly mounted with a second contact seat. The bottom of the outer surface of both the connecting seat and the sliding sleeve is fixedly mounted with a first connecting shaft. The outer surface of each of the first connecting shafts is movably fitted with a first push rod, and the front ends of the two first push rods are movably fitted with a second connecting shaft. The top of the second connecting shaft is connected to a second push rod through a universal joint. The second contact seat moves toward the direction closer to the first contact seat, and at the same time, the distance between the two first connecting shafts decreases. During this process, the first push rod pushes the second connecting shaft forward, and under the transmission action of the second push rod, pushes the travel rod and the connecting shaft sleeve forward. Specifically, the second push rod is connected to the guide device; Specifically, the first contact seat is in contact with the transmission wheel, and the second contact seat is in contact with the drive wheel.

[0007] Furthermore, the guiding device includes two mounting plates. A tail plate is fixedly mounted at the end of each mounting plate. A limit plate is fixedly mounted on the inner side of the tail plate near the end. Guide wheels are provided on the inner side of the mounting plate near the upper right and lower right. A blocking rod is fixedly mounted on the inner side of the mounting plate near the guide wheels. A locking wheel is fixedly mounted on the inner side of the mounting plate at the middle position. A first sliding hole is opened on the front of the limit plate at the middle position. An adjustment device is movably installed inside the first sliding hole. A second sliding hole is opened on both sides of the front of the limit plate at the first sliding hole. The second sliding hole cooperates with the adjustment device. A locking bolt is provided on the top of the limit plate by means of thread engagement. The locking bolt extends into the interior of the second sliding hole.

[0008] Furthermore, the adjusting device includes a connecting bushing, a stroke rod is fixedly installed on the outer surface of the connecting bushing, a circular plate is fixedly installed on the outer surface of the stroke rod near the connecting bushing, and an adjusting plate is movably installed on the outer surface of the stroke rod near its end. Limit rods are fixedly installed on both sides of the front of the adjusting plate on both sides of the stroke rod, and an adjusting spring is provided on the back of the adjusting plate on the outer side of the stroke rod. The operator can loosen the locking bolt to release the locking state of the adjusting plate and push the adjusting plate towards the connecting bushing. This operation can reduce the tension of the adjusting spring, thereby moving the tensioning wheels away from each other and reducing the tension of the cutting rope. Similarly, pushing the adjusting plate away from the connecting bushing can bring the tensioning wheels closer together and increase the tension of the cutting rope.

[0009] Specifically, the adjusting spring is connected to the circular plate, and the inner ring of the connecting bushing is movably fitted with a tensioning device; Specifically, the limiting rod is in telescopic cooperation with the second sliding hole; Specifically, the travel lever is initially in a stretched state, and the end of the travel lever is connected to the second push rod via a universal joint.

[0010] Furthermore, the tensioning device includes a third connecting shaft, on the outer surface of which a first tensioning rod and a second tensioning rod are movably sleeved respectively. The front ends of the first tensioning rod and the second tensioning rod are each movably sleeved with a tensioning wheel. As the tensioning wheels approach each other, they simultaneously drag the cutting rope, thereby tightening the cutting rope and increasing the pressure on the contact surface between the cutting rope and the raw material.

[0011] Specifically, when the cutting rope breaks during the cutting process, it loses its limiting effect on the tension wheel, causing the elastic force stored in the adjusting spring to be released.

[0012] Furthermore, the first tensioning rod and the second tensioning rod are connected by a tension spring and are in an open state under the action of the tension spring. The outer surfaces of the first tensioning rod and the second tensioning rod are in contact with the two blocking rods respectively. The ends of the first tensioning rod and the second tensioning rod are pulled backward by the connecting bushing and the stroke rod. Under the blocking action of the blocking rods, the front ends of the first tensioning rod and the second tensioning rod approach each other.

[0013] Furthermore, the cutting rope passes through the outside of the guide wheel and the inside of the tensioning wheel.

[0014] Furthermore, the protrusion on the front of the locking block is in contact with the locking groove in the initial state.

[0015] This application has the following beneficial effects.

[0016] This device can adjust the tension of the cutting rope to prevent excessive or insufficient friction between the cutting rope and the raw material. During operation, the drive wheel moves closer to the transmission wheel. If the cutting rope breaks, the drive wheel will reset and the locking groove will contact and lock with the protrusion on the front of the locking block, thus acting as a brake. Simultaneously, after the cutting rope breaks, the tensioning spring releases its stored elasticity, causing the tensioning wheels to move closer together and contact the locking wheel, thus acting as a brake to prevent the cutting rope from being thrown out. Furthermore, when the friction between the cutting rope and the raw material is too high, and the drive wheel and transmission wheel move closer together, the first connecting shaft also moves closer together. This pushes the stroke rod and connecting shaft sleeve forward via the second push rod, causing the second tensioning rod and tensioning wheel to unfold and reduce the tension of the tensioning wheel on the cutting rope. This reduces the friction between the cutting rope and the raw material, ensuring the cutting rope is in optimal working condition. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Please refer to the following: A wire saw guide device for raw material mining. Figures 1-3The device includes a base plate 1, a power chamber 2 and a connecting rib plate 3 fixedly installed on the top of the base plate 1, a power motor 4 installed on the front of the power chamber 2 near the top, a power shaft 5 fixedly installed at one end of the output shaft of the power motor 4, a sliding bushing 6 provided on the outer surface of the power shaft 5, a threaded rod 7 provided at one end of the power shaft 5, a transmission wheel 8 provided at one end of the threaded rod 7, a telescopic rod 9 provided on the front of the power chamber 2 below the power motor 4, a locking block 10 fixedly installed at one end of the output shaft of the telescopic rod 9, a protrusion provided on the front of the locking block 10, a rotating device 11 movably installed on the outer surface of the sliding bushing 6, a cutting rope 12 movably sleeved on the outer surface of the rotating device 11, a stroke device 13 provided on the front of the power chamber 2 below the telescopic rod 9, and a guide device 14 fixedly installed on the top of the connecting rib plate 3.

[0022] Please see Figures 4-5 The rotating device 11 includes a shaft ring 111, a drive wheel 112 is fixedly sleeved on the outer surface of the shaft ring 111, a sliding bearing 113 is provided on the inner ring of the shaft ring 111, an internal threaded bushing 114 is fixedly installed on the right side of the shaft ring 111, and a transmission spring 115 is provided on the outer surface of the internal threaded bushing 114 on the right side of the shaft ring 111.

[0023] Please see Figures 3-5 The inner ring of the internal threaded bushing 114 is threaded near the right end and fits with the outer surface of the threaded rod 7. One end of the transmission spring 115 is connected to the transmission wheel 8.

[0024] Please see Figures 4-5 The front of the drive wheel 112 is provided with a locking groove 116, and the locking groove 116 is distributed in a ring array.

[0025] Please see Figure 6 The travel device 13 includes a slide rod 131. A connecting seat 132 is fixedly installed at one end of the slide rod 131. A first contact seat 133 is fixedly installed at the top of the connecting seat 132. A sliding groove is provided on the outer surface of the slide rod 131, and a sliding sleeve 134 is movably installed through the sliding groove. A second contact seat 135 is fixedly installed at the top of the sliding sleeve 134. The second contact seat 135 is fixedly installed at the bottom of both the connecting seat 132 and the sliding sleeve 134. A first connecting shaft 136 is fixedly installed at the bottom of the outer surface of both the connecting seat 132 and the sliding sleeve 134. A first push rod 137 is movably sleeved on the outer surface of both the first connecting shaft 136. The front ends of the two first push rods 137 are movably sleeved on the second connecting shaft 138. The top of the second connecting shaft 138 is connected to a second push rod 139 through a universal joint.

[0026] When excessive friction occurs between the cutting rope 12 and the raw material, as the drive wheel 112 moves toward the transmission wheel 8, the first contact seat 133 contacts the transmission wheel 8, and the second contact seat 135 contacts the drive wheel 112. This causes the second contact seat 135 to move closer to the first contact seat 133, and simultaneously the distance between the two first connecting shafts 136 decreases. During this process, the first push rod 137 pushes the second connecting shaft 138 forward, and under the transmission action of the second push rod 139, pushes the stroke rod 152 and the connecting bushing 151 forward, thereby pushing the first tension rod 162 and the second tension rod 163 forward. Under the action of the tension spring, the first tension rod 162 and the second tension rod 163 unfold, reducing the tension of the tension wheel 164 on the cutting rope 12, thus reducing friction. This prevents excessive friction between the cutting rope 12 and the raw material from exceeding the cutting rope 12's tolerance limit, causing a decrease in service life or direct breakage, and improves the reliability of the device.

[0027] Please see Figure 1 and Figure 6 The second push rod 139 is connected to the guide device 14.

[0028] Please see Figure 1 and Figures 5-6 The first contact seat 133 is in contact with the transmission wheel 8, and the second contact seat 135 is in contact with the drive wheel 112.

[0029] Before operation, the telescopic rod 9 is in a retracted state, and the protrusion on the front of the locking block 10 is separated from the locking groove 116. When the power unit 4 is running, the telescopic rod 9 resets and drives the drive wheel 112 to its initial position. The torque output by the power unit 4 is transmitted to the drive wheel 112 through the transmission wheel 8 and the transmission spring 115. Since the outer surface of the drive wheel 112 is wrapped with the cutting rope 12, and the cutting rope 12 is in contact with the raw material and generates a large friction force, a torque difference is generated between the transmission wheel 8 and the drive wheel 112, which acts on the transmission spring 115, causing the transmission spring 115 to twist. After twisting, the transmission spring 115 shortens in length due to the increased number of turns, generating a lateral traction force on the drive wheel 112. The sliding bearing 113 slides laterally along the axial direction of the sliding sleeve 6, shortening the distance between the transmission wheel 8 and the drive wheel 112, and ensuring that the drive wheel 112 will not contact the locking block 10 during rotation. If the cutting rope 12 breaks during the cutting process, the friction between the cutting rope 12 and the raw material disappears, the torque difference between the transmission wheel 8 and the drive wheel 112 disappears, the transmission spring 115 resets and drives the drive wheel 112 to slide away from the transmission wheel 8, so that the locking groove 116 contacts the protrusion on the front of the locking block 10 and locks again, thereby preventing the cutting rope 12 from breaking and enabling emergency braking, preventing the broken cutting rope 12 from being thrown out and causing harm to the surrounding operators, and improving the safety performance of the device.

[0030] Please see Figures 7-9 The guide device 14 includes two mounting plates 141. A tail plate 142 is fixedly installed at the end of the mounting plate 141. A limit plate 143 is fixedly installed on the inner side of the tail plate 142 near the end. Guide wheels 144 are provided on the inner side of the mounting plate 141 near the upper right and lower right. A blocking rod 145 is fixedly installed on the inner side of the mounting plate 141 near the guide wheel 144. A locking wheel 146 is fixedly installed on the inner side of the mounting plate 141 at the middle position. A first sliding hole 147 is opened on the front of the limit plate 143 at the middle position. An adjustment device 15 is movably installed inside the first sliding hole 147. A second sliding hole 148 is opened on both sides of the first sliding hole 147 on the front of the limit plate 143. The second sliding hole 148 cooperates with the adjustment device 15. A locking bolt 149 is provided on the top of the limit plate 143 by means of thread engagement. The locking bolt 149 extends into the interior of the second sliding hole 148.

[0031] Before starting the device, the operator can loosen the locking bolt 149 to release the locking state of the adjusting plate 154 and push the adjusting plate 154 towards the connecting bushing 151. This operation reduces the tension of the adjusting spring 156, thereby moving the tension wheels 164 away from each other and reducing the tension of the cutting rope 12. Similarly, pushing the adjusting plate 154 away from the connecting bushing 151 will move the tension wheels 164 closer together and increase the tension of the cutting rope 12. The operator can fine-tune the position of the adjusting plate 154 according to the type of raw material and the maximum cutting rate that the cutting rope 12 can withstand, ensuring that the cutting rope 12 is in the best working condition, extending the working life of the cutting rope 12, reducing the operating cost of the device, and improving the practicality of the device.

[0032] Please see Figures 9-10 The adjusting device 15 includes a connecting bushing 151. A stroke rod 152 is fixedly installed on the outer surface of the connecting bushing 151. A circular plate 153 is fixedly installed on the outer surface of the stroke rod 152 near the connecting bushing 151. An adjusting plate 154 is movably installed on the outer surface of the stroke rod 152 near its end. Limit rods 155 are fixedly installed on both sides of the front of the adjusting plate 154 located on both sides of the stroke rod 152. An adjusting spring 156 is provided on the back of the adjusting plate 154 located outside the stroke rod 152. The adjusting spring 156 is connected to the circular plate 153. A tensioning device 16 is movably fitted on the inner ring of the connecting bushing 151.

[0033] Please see Figure 8 and Figure 10 The limiting rod 155 and the second sliding hole 148 are in telescopic cooperation.

[0034] Please see Figure 6 and Figure 10 In its initial state, the travel lever 152 is in a stretched state, and the end of the travel lever 152 is connected to the second push rod 139 through a universal joint.

[0035] When the cutting rope 12 breaks during the cutting process, it loses its limiting effect on the tension wheel 164, causing the elastic force stored in the adjusting spring 156 to be released. The ends of the first tension rod 162 and the second tension rod 163 move to their extreme positions. At this time, the two tension wheels 164, with the cutting rope 12 wrapped around them, come into contact with the locking wheel 146. Since the locking wheel 146 cannot rotate, the tension wheels 164 in contact with the locking wheel 146 act as brakes, preventing the cutting rope 12 from continuing to move under inertia after the drive wheel 112 stops, thus avoiding the problem of safety accidents. This further improves the safety performance of the device.

[0036] Please see Figure 11The tensioning device 16 includes a third connecting shaft 161. The outer surface of the third connecting shaft 161 is movably sleeved with a first tensioning rod 162 and a second tensioning rod 163. The front ends of the first tensioning rod 162 and the second tensioning rod 163 are movably sleeved with tensioning wheels 164.

[0037] Please see Figure 9 and Figure 11 The first tension rod 162 and the second tension rod 163 are connected by a tension spring and are in an open state under the action of the tension spring. The outer surfaces of the first tension rod 162 and the second tension rod 163 are in contact with the two blocking rods 145 respectively.

[0038] Please see Figure 9 and Figure 11 The cutting rope 12 passes through the outside of the guide wheel 144 and the inside of the tension wheel 164.

[0039] Please see Figure 2 and Figure 4 The protrusion on the front of the locking block 10 is in contact with the locking groove 116 in the initial state.

[0040] Since the travel lever 152 is initially in a stretched state, under this action, the ends of the first tension lever 162 and the second tension lever 163 are pulled backward by the connecting sleeve 151 and the travel lever 152. Under the blocking action of the blocking lever 145, the front ends of the first tension lever 162 and the second tension lever 163 move closer to each other, reducing the distance between the tensioning wheels 164. Since the cutting rope 12 passes through the outside of the guide wheel 144 and the inside of the tensioning wheel 164, the tensioning wheels 164 simultaneously drag the cutting rope 12 as they move closer together, thereby tightening the cutting rope 12 and improving the cutting speed. The pressure between the cutting rope 12 and the block material contact surface increases the static friction between the cutting rope 12 and the block material, accelerating the cutting speed and improving production efficiency. At the same time, the tightening effect of the device on the cutting rope 12 can also prevent the cutting rope 12 from being too loose and dragging on the ground, causing damage, thus improving the stability of the device during operation. In addition, tightening the cutting rope 12 can effectively keep the cutting rope 12 in the grooves on the outer surface of the tension wheel 164, guide wheel 144 and drive wheel 112, preventing the cutting rope 12 from loosening and flying out, which could cause danger to the surrounding operators, thus improving the safety performance of the device.

[0041] The method of using this invention is as follows: Before starting the device, the operator can loosen the locking bolt 149 to release the locking state of the adjusting plate 154 and push the adjusting plate 154 towards the connecting bushing 151. This operation can reduce the tension of the adjusting spring 156, thereby moving the tensioning wheels 164 away from each other and reducing the tension of the cutting rope 12. Similarly, pushing the adjusting plate 154 away from the connecting bushing 151 can move the tensioning wheels 164 closer together and increase the tension of the cutting rope 12. The operator can fine-tune the position of the adjusting plate 154 according to the type of raw material and the maximum cutting rate that the cutting rope 12 can withstand.

[0042] Before starting the power unit 4, the telescopic rod 9 is retracted, causing the protrusion on the front of the locking block 10 to disengage from the locking groove 116. When the power unit 4 is running, the telescopic rod 9 resets and drives the drive wheel 112 to its initial position. The torque output by the power unit 4 is transmitted to the drive wheel 112 through the transmission wheel 8 and the transmission spring 115. Since the outer surface of the drive wheel 112 is wrapped with the cutting rope 12, and the cutting rope 12 is in contact with the raw material and generates a large friction force, a torque difference is generated between the transmission wheel 8 and the drive wheel 112, which acts on the transmission spring 115, causing the transmission spring 115 to twist. After twisting, the transmission spring 115 shortens in length due to the increased number of turns, generating a lateral traction force on the drive wheel 112. This causes the sliding bearing 113 to slide laterally along the axial direction of the sliding sleeve 6, shortening the distance between the transmission wheel 8 and the drive wheel 112, and ensuring that the drive wheel 112 does not contact the locking block 10 during rotation. If the cutting rope 12 breaks during cutting, the friction between the cutting rope 12 and the raw material disappears, the torque difference between the transmission wheel 8 and the drive wheel 112 disappears, the transmission spring 115 resets and drives the drive wheel 112 to slide away from the transmission wheel 8, so that the locking groove 116 contacts the protrusion on the front of the locking block 10 and locks it again. Since the adjusting spring 156 is initially in a stretched state, under this action, the ends of the first tension rod 162 and the second tension rod 163 are connected. Pulled by the bushing 151 and the stroke rod 152, the first tension rod 162 and the front ends of the second tension rod 163 move closer together under the blocking action of the stop rod 145, which reduces the distance between the tension wheels 164. Since the cutting rope 12 passes through the outside of the guide wheel 144 and the inside of the tension wheel 164, the tension wheels 164 will simultaneously drag the cutting rope 12 as they move closer together, thereby tightening the cutting rope 12 and increasing the pressure on the contact surface between the cutting rope 12 and the raw material. At the same time, it increases the static friction between the cutting rope 12 and the raw material, speeds up the cutting speed, and improves production efficiency. In addition, tightening the cutting rope 12 can effectively keep the cutting rope 12 outside the tension wheel 164, the guide wheel 144, and the drive wheel 112. When the cutting rope 12 breaks during the cutting process at the surface groove, it loses its limiting effect on the tension wheel 164, causing the elastic force stored in the adjusting spring 156 to be released. The ends of the first tension rod 162 and the second tension rod 163 move backward to their extreme positions. At this time, the two tension wheels 164, with the cutting rope 12 wound on the outside, come into contact with the locking wheel 146. Since the locking wheel 146 cannot rotate, the tension wheels 164 in contact with the locking wheel 146 act as brakes. When the friction between the cutting rope 12 and the raw material becomes too great, as the drive wheel 112 moves towards the transmission wheel 8, the first contact seat 133 contacts the transmission wheel 8, and the second contact seat 135 contacts the drive wheel 112.This causes the second contact seat 135 to move closer to the first contact seat 133, while simultaneously reducing the distance between the two first connecting shafts 136. During this process, the first push rod 137 pushes the second connecting shaft 138 forward, and under the transmission action of the second push rod 139, pushes the stroke rod 152 and the connecting sleeve 151 forward, thereby pushing the first tension rod 162 and the second tension rod 163 forward. Under the action of the tension spring, the first tension rod 162 and the second tension rod 163 unfold, reducing the tension of the tension wheel 164 on the cutting rope 12, thus reducing friction.
