Detailed Description
The solution of the conveyor-type crash helmet pollution monitor provided by the embodiments of the present invention will be described in detail by several specific embodiments.
Referring to fig. 1-4, there are shown schematic structural diagrams of the conveyor-type contamination monitor of the present invention, the conveyor-type contamination monitor comprises: the device comprises a detector, a conveying device and a control device.
A detector comprising an upper detector 81 and a lower detector 82, the upper detector 81 and the lower detector 82 simultaneously detecting the crash helmet 6.
The conveying device has a conveying belt which is a transmission network 7 with a net structure, the upper detector 81 is positioned at the upper side of the transmission network 7, and the lower detector 82 is positioned at the lower side of the transmission network 7. The conveyor belt of the conveyor is transported by means of a transport network 7. When the helmet 6 is transported through the transmission network 7, the helmet 6 can be detected by the upper detector 81 and the lower detector 82 at a time. The lower detector 82 may detect the underside of the helmet through the transmission network 7. For example, the helmet 6 is placed on the transmission net 7, and the edge of the helmet 6 is in contact with the upper surface of the transmission net 7. The safety helmet 6 is in point contact with the transmission network 7. It reduces the possibility of nuclear contamination of the transmission network by the safety helmet.
And the control device is electrically connected with the detector and used for acquiring data of the detector and displaying the data acquired by the detector through the display. The control device may be a PLC controller or a computer. The PLC controller or computer receives the data from the detector. For example, the computer receives the detection signal of the upper detector 81, and if the detection signal is within a preset range, the computer displays that the safety helmet 6 is not infected through the display.
In summary, the conveyor-type helmet pollution monitor of the present invention is composed of a detector, a conveyor and a control device, when the helmet is used in a place with radiation and needs to be detected, the helmet is placed on the conveyor, and the helmet is conveyed by the conveyor and passes through the detection ends of the upper detector and the lower detector. The upper detector and the lower detector can detect the safety helmet at one time. The invention reduces the passing times of the safety helmet, reduces the contact area between the safety helmet and the transmission network, and reduces the nuclear pollution probability of the safety helmet to the transmission network. The number of times the transmission network needs to be replaced when it is contaminated is reduced.
Further, referring to fig. 4 and 5, in another embodiment of the conveyor-type helmet contamination monitor of the present invention, the conveyor further includes a plurality of rollers 4, and the plurality of rollers 4 are used for driving the transmission network 7 to operate;
the transmission network 7 comprises: weaving wires woven into the transmission net 7 with a net structure. The transmission net 7 is formed by weaving one or more weaving wires and connecting into a net. The transmission net 7 can also be formed by connecting a plurality of annular braided wire rings in a sleeved mode. For example, as shown in fig. 5, the looped woven wires include a plurality of first looped woven wires 1, a plurality of second looped woven wires 2, and a plurality of third looped woven wires 3, the plurality of third looped woven wires 3 are located in the middle of the transmission net 7, and the plurality of third looped woven wires 3 are sequentially connected to each other along the length direction of the transmission net 7 to form a force-bearing skeleton. The first annular weaving wires 1 are located on one side of the bearing framework, and the second annular weaving wires 2 are located on the other side of the bearing framework. The transmission net 7 consisting of the first annular weaving wire 1, the second annular weaving wire 2 and the third annular weaving wire 3 can ensure that the transmission net 7 is looser and still has stronger supporting force under the condition of larger aperture. The braided wire may be of metal or plastic material.
In one example, a plurality of the first looped woven wires 1 are connected to each other to form a first half transmission net, and a plurality of the second looped woven wires 2 are connected to each other to form a second half transmission net; the first half transmission net is connected with one side of the bearing framework, and the second half transmission net is connected with the other side of the bearing framework.
In another example, the first circular knitting wire 1 and the second circular knitting wire 2 are the same in shape, the first circular knitting wire 1 has the knitting wire segment thereon, and the second circular knitting wire 2 has the knitting wire segment thereon; the first annular weaving wire 1 and the second annular weaving wire 2 on two sides of the bearing framework are distributed in a relative mirror image manner; the weaving silk section of the first annular weaving silk 1 and the weaving silk section of the second annular weaving silk 2 are distributed in a relative mirror image mode. In this example, the purpose of the mirror image distribution of the knitting yarn segments of the first annular knitting yarn 1 and the second annular knitting yarn 2 is that the knitting yarn segments of the first annular knitting yarn 1 generate a first component force along the radial direction of the roller 4 under the driving of the roller 4, and in order to cancel the first component force, the knitting yarn segments of the second annular knitting yarn 2 and the roller 4 generate a second component force opposite to the first component direction, and at this time, the knitting yarn segments of the first annular knitting yarn 1 and the second annular knitting yarn 2 need to be mirror image distributed. This example creates two forces in opposite directions on the transport web 7 in the radial direction of the cylinder 4, which reduces the problem of the transport web 7 being displaced to the side of the cylinder 4 in relation to the cylinder 4 when the transport web 7 is operated by the cylinder 4.
In a specific embodiment, one side of the third circular knitting wire 3 is connected with one first circular knitting wire 1, and the other side of the third circular knitting wire 3 is connected with one second circular knitting wire 2; the length from the top to the bottom of the third circular knitting yarn 3 is gradually reduced or gradually increased; the third circular knitting wire 3 is used to maintain a relative mirror image distribution of the first circular knitting wire 1 and the second circular knitting wire 2. The third circular knitting wire 3 may be of a circular shape, for example trapezoidal, triangular, in a relatively radial direction along its centre line.
The transport net 7 comprises a friction portion 9 at the transport surface of the transport net 7, the friction portion 9 being composed of a plurality of braided wire segments, the braided wire segments being a part of the braided wires, a part of the braided wire segments being in a first position state with respect to the body of the transport net 7, another part of the braided wire segments being in a second position state with respect to the body of the transport net 7. The friction portion 9 is a surface portion of the transport web 7, which surface portion of the transport web 7, i.e. the friction portion 9, is contacted by the roller 4 when the roller 4 moves the transport web 7. The friction portion 9 generates a force component with the roller 4 in the radial direction of the roller 4. With respect to the transmission mesh 7, as shown in fig. 5, in one embodiment, specific a braided wire segment 11, B braided wire segment 12, C braided wire segment 13, D braided wire segment 14, E braided wire segment 21, F braided wire segment 22, G braided wire segment 23, and H braided wire segment 24 among a plurality of braided wire segments are illustrated on the transmission mesh 7.
For example, the a-knitted wire segment 11 is the bottom portion of the first endless knitted wire 1, and when the roller 4 drives the transmission net 7 to run, the a-knitted wire segment 11 contacts with the surface of the roller 4. In fig. 5, since the diameter of the a-braid wire segments 11 is at an angle to the radial direction of the drum 4, a first axial force component is imparted to the transport web 7 between the a-braid wire segments 11 and the drum 4 relative to the axial direction of the drum 4, which first axial force component deflects the transport web 7 in the axial direction of the drum 4. The principle and effect of the braided wire sections B12, C13 and D14 in FIG. 5 are the same as those of the braided wire section A11, and thus the description is omitted.
The E weaving wire section 21 is the bottom part of the second annular weaving wire 2, and when the roller 4 drives the transmission net 7 to run, the E weaving wire section 21 is contacted with the surface of the roller 4. In fig. 5, the diameter of the E-braid wire section 21 is angled with respect to the radial direction of the drum 4, so that a second axial force component is generated between the E-braid wire section 21 and the drum 4 with respect to the axial direction of the drum 4 by the transmission net 7. This second axial component will deflect the transport web 7 in the axial direction of the drum 4. And the second axial force component is opposite to the first axial force component in direction, and the two components can be mutually offset. The principle and effect of the F braided wire section 22, the G braided wire section 23 and the H braided wire section 24 in FIG. 5 are the same as those of the E braided wire section 21, and thus the description is omitted.
The lengths of knitting yarn in the first position generate a first axial force component with the drum 4 in the axial direction of the drum 4 at the portion where the friction portion 9 contacts the drum 4. The length of knitting yarn in the second position generates a second axial force component with the drum 4 in the axial direction of the drum 4. The first axial force component and the second axial force component are opposite in direction. Eventually the first axial force component and the second axial force component may cancel.
In contrast to the prior art transmission network 8, the friction portion 9 is set in two position states, a first position state and a second position state. The weaving silk section in the first position state and the roller 4 generate a component force in one direction, the weaving silk section in the second position state and the roller 4 generate a component force in the other direction, and the single axial direction offset force of the transmission net and the roller is eliminated through mutual offset of the forces between the weaving silk sections in the two position states. Finally, the noise and the damage at the position of the roller limiting shaft are avoided.
Further, in another embodiment of the conveyorized pollution monitor according to the present invention, the first axial force component is directed towards one side of the transport network 7 and the second axial force component is directed towards the other side of the transport network 7. The first and second axial force components are used to spread the body of the transmission network 7 to both sides thereof. In the present embodiment, when the orientation of the knitted yarn segments on the transport net 7 is set, specifically, the following example is used, and when a plurality of knitted yarn segments on the left side of the transport net 7 are set, the orientation of the plurality of knitted yarn segments on the left side is set, and the plurality of knitted yarn segments on the left side and the drum 4 generate a component force to the left side of the drum 4. The right-hand weaving yarn segments are fixed in position, and generate a force component towards the right side of the roller 4 with the roller 4. Thus, when the transmission net 7 is driven by the roller 4 to operate, the transmission net 7 is unfolded towards two sides. When the woven wire used for the transmission net 7 is fine and the mesh is large, the supporting force of the transmission net 7 as a whole is low. If the transmission network 7 can be unfolded towards both sides, the transmission network 7 also tends to be straightened in length, which increases the overall stability of the transmission network 7 and increases the carrying capacity of the transmission network 7.
For example, the braided wire segment in the first position state is located on one side of the braided wire, and the braided wire segment in the second position state is located on the other side of the braided wire. With respect to the transmission mesh 7, as shown in fig. 5, in one embodiment, specific a braided wire segment 11, B braided wire segment 12, C braided wire segment 13, D braided wire segment 14, E braided wire segment 21, F braided wire segment 22, G braided wire segment 23, and H braided wire segment 24 among a plurality of braided wire segments are illustrated on the transmission mesh 7. The A braided wire section 11, the B braided wire section 12, the C braided wire section 13 and the D braided wire section 14 are positioned on the left side of the transmission net 7. The E braided wire section 21, the F braided wire section 22, the G braided wire section 23 and the H braided wire section 24 are located on the right side of the transmission net 7. The above arrangement allows the pulling force to be increased on both sides of the entire transmission network 7. The entire transmission network 7 is more fully extended to both sides. The overall stability of the entire transmission network 7 is greatly increased and the carrying capacity of the transmission network 7 is greatly increased.
Further, referring to fig. 5, in another embodiment of the conveyor-type helmet contamination monitor of the present invention, the transmission net 7 further includes a transmission net skeleton, the transmission net skeleton is connected to the transmission net 7, and the transmission net skeleton is configured to maintain a portion of the braided wire segments in the first position state and maintain another portion of the braided wire segments in the second position state. Since the transmission net 7 is woven by the knitting yarn, the strength of the entire transmission net 7 is low particularly when the knitting yarn is thin and the mesh is large. By adding the transmission network framework to the transmission network 7, the overall strength and bearing capacity of the transmission network 7 are greatly enhanced.
Further, referring to fig. 5, in another embodiment of the conveyor-type helmet contamination monitor of the present invention, the transmission net frame is a portion of the woven wire. As shown in fig. 5, the transmission net skeleton may be a transmission net skeleton formed by connecting a plurality of third endless braided wires in fig. 5 to each other and located in the middle of the transmission net 7. The transmission net framework can also be formed by winding the braided wires with each other or bonding a plurality of braided wires adjacently to form the transmission net framework with the diameter larger than that of the braided wires. The transport net skeleton is a part of the weaving filaments and can be formed by weaving the transport net 7. This embodiment can significantly reduce the time required to manufacture the transmission network 7. When other materials are added, the machine is stopped to add other materials, so that the production efficiency is prevented from being influenced.
Referring to fig. 4, the present invention further provides a conveying device, which includes the above-mentioned transmission net for preventing deviation, which is dedicated for the apparatus for measuring and sorting contamination of clothes. The conveyor further comprises a tensioning device 5 for tensioning the transport web. The transmission network 7 is used for transmitting the transmitted object 6.
Further, referring to fig. 7, in another embodiment of the conveyor-type helmet contamination monitor of the present invention, the diameter of the end portion of the drum 4 is gradually reduced to the diameter of the middle portion of the drum 4.
By forming a stable concave structure on the middle side of the transmission net 7 along the length direction of the transmission net 7 under the combined action of the plurality of rollers 4, the whole transmission net 7 is deflected to the middle of the roller 4, which can make the middle of the transmission net 7 form a structure with a collapsed middle, so that the safety helmet 6 tends to deflect to the middle when the safety helmet 6 is conveyed. Meanwhile, the transmission net 7 tends to deviate towards the middle, and the effect of the transmission net is that the abrasion of the transmission net 7 to the steps at the two sides of the roller 4 is reduced, the abrasion of the roller 4 to the steps is greatly reduced, the transmission net 7 can be normally used for a long time, the noise is reduced, and the problems of abrasion and deviation are greatly reduced.
Further, referring to fig. 3, in another embodiment of the conveyor-type helmet contamination monitor according to the present invention, the conveyor-type helmet contamination monitor further includes a frame body 8, the upper end of the frame body 8 has a detection chamber, and the lower end of the frame body 8 has a power distribution chamber. The detector and the conveying device are arranged in the detection chamber. The power distribution room is provided with a power supply device and a motor, the motor is electrically connected with the power supply device, and the motor is used for providing power for the conveying device. The frame body 8 is a framework of the conveyor belt type safety helmet pollution monitor and plays a supporting role.
The bottom of the frame body 8 is provided with four horse-moving wheels 84, and the four horse-moving wheels 84 are uniformly distributed at the bottom of the frame body 8. By arranging the four Fuma wheels 84, the conveyor belt type safety helmet pollution monitor can be moved conveniently and transported conveniently.
The conveyor belt type safety helmet pollution monitor further comprises an alarm component 83, the alarm component 83 is arranged at the top of the frame body 8, and the alarm component 83 is electrically connected with the control device. The alarm component 83 is used to prompt the user whether the safety helmet 6 is contaminated. The phenomenon of missing detection when the user does not watch the display carefully is avoided.
Further, referring to fig. 3, in another embodiment of the conveyor-type contamination monitor for safety helmets according to the present invention, the shielding lead plate is coated with a layer of stainless steel on the outer surface. The shielding lead plate is wrapped by stainless steel to form a shielding plate assembly which is used for increasing detection energy.
