Description

Technical Field

[0001] The invention relates to the technical field of belt conveyor equipment, in particular to a blasting detonator transportation device with an anti-bumping function. Background Art

[0002] If detonators encounter bumps during transportation and actual application, it is very likely to induce a series of serious safety problems. Specifically, during the transportation process, severe bumps may cause damage to the internal structure of the detonator, such as loose or broken bridge wires, leg wires falling off, and other potential risks. At the same time, it may also cause the failure of the sealing performance of the detonator, making it susceptible to deterioration due to humid environments. In view of this, in order to ensure the safe use of detonators, a series of rigorous measures must be taken to effectively prevent bumps and damage during transportation and use.

[0003] In view of the current application status of belt conveyor equipment, the wear of the shaft due to long-term operation cannot be ignored. This wear can cause the position of the driving wheel and the driven wheel to deviate, which in turn causes the belt to deviate from the established center line during operation, resulting in vibration problems. Although this type of wear is an inevitable phenomenon during the operation of the equipment, it can be alleviated by regularly spraying lubricating oil and implementing precise testing. In addition, exploring and adopting more optimized transmission methods can also reduce shaft wear to a certain extent, thereby effectively reducing the vibration amplitude of the belt conveyor equipment and improving the overall operation stability. Summary of the invention

[0004] The purpose of the present invention is to provide a blasting cap transportation device with an anti-bumping function to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a transport device for blasting detonators with anti-bumping function comprises a chassis, a driving mechanism, a roller mechanism, a transmission mechanism and a control box, the driving mechanism comprises a first motor, an assembly frame and a first magnetic wheel, the roller mechanism comprises a second magnetic wheel, a supporting mechanism, a distance adjustment mechanism and a third magnetic wheel, the supporting mechanism comprises a bottom plate, the distance adjustment mechanism comprises a second motor, the transmission mechanism comprises a side frame and a fourth magnetic wheel, the first motor, the assembly frame, the bottom plate and the second motor are all fixedly connected to the chassis, the first motor and the second motor are both connected to the control box through electrical signals, the first magnetic wheel is connected to the second magnetic wheel through magnetic transmission, and the third magnetic wheel is connected to the fourth magnetic wheel through magnetic transmission.

[0006] The present invention relates to a transfer and conveying device specially designed for detonator jigs. During the conveying process of detonator assemblies, if severe vibration or bumping occurs, it is very likely that the wire bridge or foot wire inside the detonator will fall off or even break. This potential problem will directly lead to serious safety hazards. Conventional transfer devices have bumps when transporting jigs. The present invention outputs torque to a first magnetic wheel through a first motor, and transmits torque to the second magnetic wheel through magnetic transmission between the first magnetic wheel and the second magnetic wheel. The second magnetic wheel is fixedly assembled with a third magnetic wheel, and the torque is transmitted through the magnetic connection between the third magnetic wheel and the fourth magnetic wheel. The torque can be effectively reduced by transmitting the torque through the magnetic force, and the bumping of the conveyor belt can be avoided. A plurality of groups of linearly evenly distributed roller mechanisms rotate to drive the belt to transport the detonator jig, and the torque is adjusted by the first motor to change the conveying speed.

[0007] Furthermore, the driving mechanism also includes a coupling, the coupling is fixedly connected to the output end of the first motor and the first magnetic wheel, and the coupling is rotatably connected to the assembly frame.

[0008] The first motor outputs a fixed-axis torque to the coupling, the coupling rotates in the assembly frame, the coupling transmits torque to the first magnetic wheel, and the first magnetic wheel rotates on a fixed axis, thereby reducing the influence of the vibration of the driving end on the transport end.

[0009] Furthermore, the roller mechanism is provided with several groups, and the several groups of roller mechanisms are linearly evenly distributed along the base frame. The roller mechanism also includes a differential roller. The support mechanism also includes a support frame and a pressure sensor. The support frame is provided with side holes and slide grooves. There are two groups of side holes, and the two groups of side holes are provided on both sides of the differential roller. The side holes are rotatably connected to the second magnetic wheel and the third magnetic wheel. The differential roller includes a differential mechanism and a main shaft. The main shaft is fixedly connected to the second magnetic wheel and the third magnetic wheel. The distance adjustment mechanism includes a first support seat and a second support seat. The first support seat and the second support seat are both slidably connected to the slide groove. The first support seat and the second support seat are both rotatably connected to the differential roller. The differential mechanism includes a servo cylinder, and the pressure sensor is connected to the second motor and the servo cylinder through electrical signals.

[0010] A plurality of groups of linearly evenly distributed roller mechanisms rotate to drive the belt to transport the detonator jig. The second magnetic wheel rotates in the side hole. The second magnetic wheel and the third magnetic wheel are connected by the main shaft. The third magnetic wheel rotates in the side hole on the other side. The overall support effect of the differential roller on the jig can be adjusted by changing the distance between the first support seat and the second support seat. The weight distribution of the jig is detected by the pressure sensor, so that the positions of the first support seat and the second support seat are located on both sides of the center of gravity of jigs of different sizes. The arrangement of the rollers is optimized, which can effectively improve the stability of the conveyor belt. The differential speed of the differential roller is adjusted by the servo cylinder to correct the posture of the jig and transport the jig to the center line of the conveyor belt.

[0011] Furthermore, the supporting mechanism also includes spring damping. There are four groups of spring damping and pressure sensors. The four groups of spring damping and pressure sensors are arranged at the four corners of the base plate. The pressure sensor is fixedly connected to the base plate, and the spring damping is fixedly connected to the supporting frame and the pressure sensor.

[0012] The bottom plate is installed on the chassis. The four sets of spring dampers evenly distributed at the four corners of the bottom plate can effectively absorb and slow down the vibration energy, thereby reducing the bumpiness of the conveyor belt. The pressure difference of the four sets of pressure sensors evenly distributed at the four corners can be used to determine the center of gravity of the fixture. By sending an electrical signal to the servo cylinder to adjust the differential roller differential, the posture of the fixture can be corrected so that the center of gravity of the fixture is located on the center line of the conveyor belt, ensuring smooth transportation of the fixture.

[0013] Furthermore, the pitch adjusting mechanism also includes a threaded rod and a first pulley, the first pulley is fixedly connected to the second motor output end and the threaded rod, the adjacent first pulleys are connected by belt transmission, the first support seat is provided with a first threaded hole, the second support seat is provided with a second threaded hole, the first threaded hole and the second threaded hole are both threadedly connected to the threaded rod, and the first threaded hole and the second threaded hole have opposite threaded rotation directions, the differential roller also includes a first side cylinder, an outer bearing, an inner bearing, a first compression cylinder, a second compression cylinder, and a second side cylinder, the outer bearing and the inner bearing are each provided with two groups, one group of inner bearings are rotatably connected to the first support seat and the first compression cylinder, the other group of inner bearings are rotatably connected to the second support seat and the second compression cylinder, one group of outer bearings are rotatably connected to the first side cylinder and the first support seat, and the other group of outer bearings are rotatably connected to the second side cylinder and the second support seat.

[0014] When adjusting the spacing between the first support seat and the second support seat, the second motor outputs torque to the first pulley, and the adjacent first pulleys are connected by belt transmission to achieve synchronous adjustment of several linearly evenly distributed roller mechanisms. The first pulley is fixedly assembled with a threaded rod, and the threaded rod rotates to transmit torque to the first support seat and the second support seat through the threaded connection with the first threaded hole and the second threaded hole. The first threaded hole and the second threaded hole have opposite threaded rotation directions. When the threaded rod rotates in a directional manner, the first support seat and the second support seat are synchronously displaced the same distance toward or away from each other. The first support seat drives the first side cylinder and the first compression cylinder to displace along the main shaft through the outer bearing and the inner bearing. The main shaft transmits torque to the first side cylinder, and the second support seat drives the second compression cylinder and the second side cylinder to displace along the main shaft.

[0016] When the first compression cylinder and the second compression cylinder are synchronously displaced toward or away from each other along the main shaft, the first spline and the second spline slide relative to each other, and the first compression cylinder and the second compression cylinder squeeze the compression spring, so that the first compression cylinder and the second compression cylinder are located on both sides of the center of gravity of different sizes of jigs. The arrangement of the rollers is optimized, which can effectively improve the stability of the conveyor belt. The conical cylinder contacts the inclined arc surface to transmit torque, so that there is a differential speed between the first compression cylinder and the first side cylinder, and the posture of the jig is corrected so that the center of gravity of the jig is located on the center line of the conveyor belt, thereby ensuring the smooth transportation of the jig.

[0017] Furthermore, the differential mechanism also includes an assembly ring and a swivel ring. The assembly ring is fixedly connected to the output end of the servo cylinder, the swivel ring is rotatably connected to the assembly ring, and the swivel ring is in contact with both the main shaft and the cone cylinder.

[0018] The output end of the servo cylinder pushes the assembly ring, which moves along the main shaft to change the position where the swivel contacts the cone cylinder. When the swivel contacts the cone cylinder close to the tip of the cone, the speed ratio of the swivel transmitted by the cone cylinder is greater than the speed ratio when the swivel contacts the cone cylinder away from the tip of the cone. The cone cylinder transmits the swivel to the inclined arc surface, so that there is a speed difference between the first compression cylinder and the first side cylinder.

The adjacent first pulleys 333 are connected by belt transmission to achieve synchronous adjustment of several linearly evenly distributed roller mechanisms 3. When the threaded rod 332 rotates in a directional manner, the first support seat 334 and the second support seat 335 are synchronously displaced the same distance toward or away from each other. The first compression cylinder 344 and the second compression cylinder 345 are synchronously displaced toward or away from each other along the main shaft 349, so that the first compression cylinder 344 and the second compression cylinder 345 are located on both sides of the center of gravity of different sizes of fixtures, and the arrangement of the rollers is optimized, which can effectively improve the stability of the conveyor belt. The pressure sensor 323 sends an electrical signal to the servo cylinder 3483, and the output end of the servo cylinder 3483 pushes the assembly ring 3484, which is displaced along the main shaft 349, changing the contact between the swivel 3485 and the cone cylinder The position of 3482, when the swivel 3485 contacts the cone cylinder 3482 close to the cone tip, the cone cylinder 3482 transmits the rotation speed ratio of the swivel 3485 to be greater than the rotation speed ratio when the swivel 3485 contacts the cone cylinder 3482 away from the cone tip. The cone cylinder 3482 transmits the swivel 3485 to the inclined arc surface 3442, so that there is a speed difference between the first compression cylinder 344 and the first side cylinder 341, and the posture of the jig is corrected, so that the center of gravity of the jig is located on the center line of the conveyor belt, thereby ensuring the smooth transportation of the jig.
