Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of on-site mixed explosive truck, and particularly relates to an auxiliary device for charge depth control of a mixed explosive truck. BACKGROUND

[0002] The on-site mixed explosive production mode adopts a mode of using a fixed ground preparation station in cooperation with an on-site mixed explosive truck, and the latex matrix is produced in the ground station and is distributed remotely through the mixed explosive truck, and the on-site mixed explosive truck loads raw materials such as the latex matrix in the blasting construction site to perform sensitization or mechanical mixing. This mode has the following advantages: first, no need to install production and charging equipment on site, but to complete the integration by the mixed explosive truck, to reduce the construction process and improve the intrinsic safety; second, to promote the optimization of blasting parameters, to reduce the drilling quantity and labor cost; third, mechanical charging, high charging efficiency. The on-site mixed explosive truck technology replaces the traditional explosive preparation, storage, transportation and manual loading process and method, can meet the requirements of on-site mining intensity, and can solve the safety hidden trouble from the essence.

[0003] In the on-site mixed explosive truck technology, the charge depth control is a very important operation process, and the accuracy of the charge depth affects the length of the plug and the unit consumption of explosives, and further affects the blasting effect and construction cost. The traditional charge depth control is to use the manual pull tape or long rod detection method, which needs multiple on-site construction personnel to complete, and due to manual control, the precision is low. Furthermore, the traditional manual control is based on the possibility of idling of the feeding pump of the mixed explosive truck, which leads to the discontinuity and instability of the explosive in the conveying pipeline, and further cannot use the flow metering method to calculate the conveying explosive quantity.

[0004] Based on the above reasons, the Chinese invention patent with publication number CN108264442B proposes a charging depth control system and control method for mixed ammonium oil explosive truck, which improves the charging depth control precision through the monitoring of the pressure sensor. Specifically, the pressure sensor is arranged at one end of the lead wire, the control input end of the electric winch is connected to the electric winch control output end of the controller, the controller controls the rotation of the electric winch to put the pressure sensor into the blast hole, the pressure sensor output end is connected to the pressure signal input end of the controller, the pressure sensor collects the pressure signal of the explosive and sends it to the controller, and the controller injection control output end is connected to the injection control valve control end. The controller controls the injection control valve to deliver explosive to the explosive delivery pipe according to the pressure signal. The control system is simple to operate, has high precision, avoids human factor interference, and improves the efficiency of on-site construction. However, since the pressure sensor is inserted into the blast hole, it is easily damaged by intermittent impact of the explosive during the charging process, thereby affecting the repeatability of the device and the monitoring precision of the reuse, therefore, the sustainability effect of the existing charging depth control system is not good, and the maintenance cost is high.

[0047] The fixed end of the lifting member 3 is fixedly connected to the housing 1, and the top is a telescopic end, the telescopic end is connected to the storage cylinder 2 to drive the storage cylinder 2 to ascend and hang in the housing 1 or to descend and approach the lower through opening 1.2, and a gravity sensor is arranged on the telescopic end of the lifting member 3, and the gravity sensor is used for monitoring the gravity of the storage cylinder 2. The lifting member 3 makes the weighing of the storage cylinder 2 more accurate by hanging the storage cylinder 2, which is more conducive to improving the accuracy of charge control. The lifting member 3 preferably adopts the structure of an electric push rod, and preferably at least two electric push rods are arranged uniformly.

[0048] The sealing member comprises a cylinder connecting plate 4, an intermediate sealing plate 5, a driving plate 6, a rotary driving member and a horizontal sliding member. The cylinder connecting plate 4, the intermediate sealing plate 5 and the driving plate 6 are arranged in sequence along the direction from the bottom of the storage cylinder 2 to the lower opening 1.2, wherein the cylinder connecting plate 4 is annularly mounted on the bottom of the storage cylinder 2 and has a structure of a rectangular plate with a hole in the middle, i.e. the bottom of the storage cylinder 2 passes through the hole in the middle and the cylinder connecting plate 4 is annularly arranged around the circumference of the storage cylinder 2, and the bottom of the storage cylinder 2 does not protrude out of the cylinder connecting plate 4. Both ends of the diagonal line of the cylinder connecting plate 4 are provided with cylinder connecting A parts 4.1, the distance between the cylinder connecting A parts 4.1 at the two ends is greater than the width or length of the cylinder connecting plate 4, and the distance between each cylinder connecting A part 4.1 and the center of the diagonal line of the cylinder connecting plate 4 is the same. The top surface of the intermediate sealing plate 5 has cylinder connecting B parts 5.1 matching the cylinder connecting A parts 4.1, and the intermediate sealing plate 5 is detachably connected to the cylinder connecting plate 4 by connecting the cylinder connecting A parts 4.1 through the cylinder connecting B parts 5.1; at least two driving connecting A parts 5.2 are arranged on the side of the intermediate sealing plate 5 facing the driving plate 6, and all the driving connecting A parts 5.2 are on the same circumference. The driving plate 6 is rotatably mounted on the horizontal sliding member by the rotary driving member, the center of rotation passes through the center of the circumference where the driving connecting A parts 5.2 are located and the center of the diagonal line of the cylinder connecting plate 4, and the horizontal sliding member is mounted on the shell 1, which drives the rotary driving member and the driving plate 6 to slide on the shell 1, so as to make the driving plate 6 staggered with the bottom of the storage cylinder 2 or directly opposite to the bottom of the storage cylinder 2; the driving plate 6 is provided with driving connecting B parts 6.2 matching the driving connecting A parts 5.2, and the driving plate 6 is detachably connected to the intermediate sealing plate 5 by connecting the driving connecting A parts 5.2 through the driving connecting B parts 6.2; the driving connecting B parts 6.2 and the driving connecting A parts 5.2, and the cylinder connecting B parts 5.1 and the cylinder connecting A parts 4.1 are detachably connected by driving the driving plate 6 to rotate on the horizontal sliding member by the rotary driving member, and when the driving plate 6 is connected to the intermediate sealing plate 5 by connecting the driving connecting B parts 6.2 and the driving connecting A parts 5.2, the cylinder connecting B parts 5.1 and the cylinder connecting A parts 4.1 do not connect the intermediate sealing plate 5 and the cylinder connecting plate 4, and vice versa, when the driving connecting B parts 6.2 and the driving connecting A parts 5.2 do not connect the driving plate 6 and the intermediate sealing plate 5, the cylinder connecting B parts 5.1 and the cylinder connecting A parts 4.1 are connected to connect the intermediate sealing plate 5 and the cylinder connecting plate 4, and at this time, the intermediate sealing plate 5 seals the bottom of the storage cylinder 2.

[0049] The controller is further connected with the lifting member 3, the gravity sensor, the rotary driving member and the horizontal sliding member.

[0050] That is, through the setting of the sealing piece, the control of the charging depth can be realized. Specifically, the middle sealing plate 5 in the sealing piece is connected with the barrel connecting plate 4 to seal the bottom of the storage barrel 2, so that when the lifting piece 3 suspends the storage barrel 2, the storage barrel 2 forms an open-top storage space, and the conveying pipeline 40 conveys the explosive into the storage space through the open top, so that the gravity sensor on the lifting piece 3 supporting the storage barrel 2 can perform a weighing operation on the storage barrel 2 and the explosive in it, and the controller can know how much explosive is stored in the storage space according to the gravity information detected by the gravity sensor, and through the acquisition of the amount of explosive, the construction personnel can know the amount of explosive to be loaded into the blast hole in time, so as to control the mixed explosive truck to stop outputting the explosive. According to the capacity of the storage barrel 2, the present application can store and release the explosive into the blast hole in batches. During the explosive releasing process, that is, after the mixed explosive truck stops outputting the explosive into the storage barrel 2, the lifting piece 3 operates under the control of the controller until the storage barrel 2 is lowered to the middle sealing plate 5 which is placed on the driving plate 6, and at the time of placing, the driving connection B part 6.2 on the driving plate 6 is aligned with the driving connection A part 5.2 on the middle sealing plate 5, and the rotary driving piece operates under the control of the controller to drive the driving plate 6 to rotate on the horizontal sliding piece. During the rotation process, the driving plate 6 drives the middle sealing plate 5 to rotate relative to the barrel connecting plate 4 through the connection of the driving connection B part 6.2 and the driving connection A part 5.2, and the rotation of the middle sealing plate 5 will promote the barrel connecting B part 5.1 thereon to gradually separate from the barrel connecting A part 4.1 on the barrel connecting plate 4. When the barrel connecting B part 5.1 and the barrel connecting A part 4.1 are completely separated and the barrel connecting B part 5.1 is separately arranged on the opposite sides of the barrel connecting plate 4 and the barrel connecting B part 5.1 is not in contact with the barrel connecting plate 4, the rotary driving piece stops rotating, and the horizontal sliding piece operates under the control of the controller to promote the driving plate 6 to slide outward (the sliding direction is perpendicular to the connecting line of the two barrel connecting B parts 5.1) with the middle sealing plate 5 connected thereto, so that the driving plate 6 and the middle sealing plate 5 do not block the bottom of the storage barrel 2, that is, the bottom of the storage barrel 2 is opened, and the explosive in the storage barrel 2 falls into the blast hole from the bottom and the lower opening 1.2, and after the explosive releasing is completed, the controller drives the horizontal sliding piece to operate in the reverse direction to reset the driving plate 6 and the middle sealing plate 5, and the middle sealing plate 5 re-seals the bottom of the storage barrel 2. If the explosive needs to be continuously charged (judged by the controller according to the weight value detected and calculated by the gravity sensor compared with the preset value of the amount of explosive to be charged), then the controller drives the rotary driving piece to rotate in the reverse direction, so that the driving plate 6 drives the middle sealing plate 5 to rotate until the barrel connecting B part 5.1 on the middle sealing plate 5 and the barrel connecting A part 4.1 on the barrel connecting plate 4 are connected, and then the controller drives the lifting piece 3 to operate to suspend the storage barrel 2, and the middle sealing plate 5 is separated from the driving plate 6 and rises, and the above operation can be repeated to realize the explosive charging and releasing operation.

[0051] In other words, the present application realizes the accurate control of the charging depth in the blast hole by the way of weighing, which can be more accurate to a certain extent, and the structure is less likely to be damaged during the charging process, solving the defects of the existing way that the repeated use accuracy is not high and the maintenance cost is high due to damage.

[0052] In the present application, the structures of the cylinder connecting B part 5.1 and the cylinder connecting A part 4.1, the driving connecting B part 6.2 and the driving connecting A part 5.2 in the sealing part are various.

[0053] For example, as shown in Figures 11-12 , the cylinder connecting A part 4.1 is the end corner of the cylinder connecting plate 4, and the cylinder connecting B part 5.1 is the sleeve structure installed on the top surface of the intermediate sealing plate 5, which is connected by rotating to make the sleeve cover the cylinder connecting A part 4.1. For another example, Figures 15-16 , the cylinder connecting A part 4.1 and the cylinder connecting B part 5.1 are the clamping mechanism composed of the first clamping groove 4.1.1 and the first clamping block 5.1.1, wherein the cylinder connecting A part 4.1 is the first clamping groove structure, and the cylinder connecting B part 5.1 is the first clamping block structure, which facilitates the sliding of the intermediate sealing plate 5 relative to the storage cylinder 2 and the cylinder connecting plate 4 to open or close the storage cylinder 2; the first clamping groove structure is a groove structure opened upward from the bottom surface of the cylinder connecting plate 4 and extending to the side wall of the cylinder connecting plate 4, which is a T-shaped groove structure with a bottom (as shown in Figure 17 (b)) or a through groove structure without a bottom (as shown in Figure 17 (a)); the first clamping block structure includes a clamping rod and a clamping plate, the size of the clamping plate is greater than the rod diameter of the clamping rod, the clamping plate is installed on the intermediate sealing plate 5 through the clamping rod, and the clamping plate abuts against the cylinder connecting plate 4 when the clamping rod is clamped into the first clamping groove structure, at this time, the intermediate sealing plate 5 is connected to the cylinder connecting plate 4; that is, the clamping rod is clamped into the first clamping groove structure in the process of sliding the intermediate sealing plate 5, the clamping plate is in the horizontal side of the T-shaped groove structure when the groove structure is a T-shaped groove structure with a bottom, and contacts the top surface of the cylinder connecting plate 4 when the groove structure is a through groove structure without a bottom, after lifting the cylinder connecting plate 4, the clamping plate is subjected to the force of the cylinder connecting plate 4, the intermediate sealing plate 5 cannot fall, and it is connected together with the cylinder connecting plate 4, which can be lifted together with the storage cylinder 2.

[0054] For the driving connecting B part 6.2 and the driving connecting A part 5.2, they can be the same as the structure of the cylinder connecting B part 5.1 and the cylinder connecting A part 4.1, or they can be different. As shown in Figures 11-12 , when the intermediate sealing plate 5 is a plate structure with an end corner structure, the driving connecting A part 5.2 is the end corner of the intermediate sealing plate 5, and the driving connecting B part 6.2 is the sleeve structure covering the end corner. For another example, Figures 15-16The driving connection A part 5.2 and the driving connection B part 6.2 are the second clamping groove 5.2.1 and the second clamping block 6.1.1 structure. In this clamping groove and clamping block connection mode, it is not limited that which one of the driving connection A part 5.2 and the driving connection B part 6.2 must be the clamping groove structure. In addition, since the cooperation of the driving connection A part 5.2 and the driving connection B part 6.2 only needs to provide the driving force for the rotation of the intermediate sealing plate 5, it is not necessary to provide the downward force to connect the intermediate sealing plate 5 and the driving plate 6, therefore, the clamping groove structure of the driving connection A part 5.2 and the driving connection B part 6.2 can be various, such as Figure 15 The single hole structure (both blind hole and through hole) can also be such as Figure 16 The arc-shaped strip structure, or the groove structure of the first clamping groove structure, of course, when the groove structure of the first clamping groove structure, the second clamping block can provide the vertical force to connect the intermediate sealing plate and the driving plate 6, so that the movement of the intermediate sealing plate 5 caused by the lifting of the storage cylinder 2 can be well avoided. Further, in order to better drive the intermediate sealing plate 5, the driving connection A part 5.2 is uniformly arranged on the intermediate sealing plate 5.

[0055] Further, the bottom of the storage cylinder 2 is provided with a cylinder cover for sealing the bottom of the storage cylinder 2, one end of the cylinder cover is rotatably connected with the storage cylinder 2; the cylinder cover abuts against the intermediate sealing plate 5 when the intermediate sealing plate 5 connects the cylinder connecting plate 4; in this way, when the intermediate sealing plate 5 is staggered with the bottom of the storage cylinder 2, the bottom of the cylinder cover has no supporting force, and it rotates downward under the action of the explosive to open, when the intermediate sealing plate 5 is reset, the cylinder cover is resealed with the storage cylinder 2 under the action of the intermediate sealing plate 5. The setting of the cylinder cover can avoid the direct contact of the explosive with the intermediate sealing plate 5 to some extent, and reduce the possibility of explosive damage.

[0056] Further, the top of the shell is provided with two cover plates 10 for closing the upper through opening 1.1, the two cover plates 10 are slidingly arranged on the top of the shell, and the two cover plates 10 abut against each other by sliding relative to the shell to close the upper through opening 1.1 or separate from each other to open the upper through opening 1.1; the shell is provided with a locking member 10.1 for preventing the cover plates 10 from sliding relative to the shell. The present application can close the upper through opening 1.1 of the shell by the arrangement of the two cover plates 10 when the device is not needed to be used, and the lower through opening 1.2 is closed after the reset of the driving plate 6, so that the shell can be in a certain sealed state when not in use, which is convenient for protecting the structure inside the shell and plays a dustproof role; further, the arrangement of the locking member 10.1 can make the cover plates 10 in a stable closed state or open state, and when in the open state, it can also be used to clamp the conveying pipeline 40, so that the device can be preliminarily fixed on the conveying pipeline 40. Preferably, the end of the two cover plates 10 abutting against each other is provided with a bumper strip, which is made of anti-skid rubber or silicone material, so as to better clamp the conveying pipeline 40 or keep the closed state. The locking member 10.1 is a common locking structure composed of a screw and a nut.

[0057] Further, the bottom of the shell 1 is spaced apart with a plurality of distance measuring sensors 20, which are arranged circumferentially around the lower opening 1.2, each distance measuring sensor 20 is spaced apart from the center of the circle where the driving connection A part 5.2 is located by a distance not greater than the radius of the blast hole, each distance measuring sensor 20 is connected to a controller, and the distance measuring sensor 20 is used to measure the distance from the ground or the bottom of the blast hole or the upper plane of the explosive in the blast hole, wherein the measurement from the ground is supplemented by the measurement from the bottom of the blast hole, which can better adjust the position of the conveying pipe 40, so that the conveying pipe 40 and the storage drum 2 can be located directly above the blast hole, that is, all distance measuring sensors 20 measure the distance, which is not the distance measured from the ground, and is approximately equal to the sum of the distance measured from the ground and the depth of the blast hole, which means that the conveying pipe 40 and the storage drum 2 have been located directly above the blast hole, so that the explosive in the storage drum 2 can be completely loaded into the blast hole, and the distance from the upper plane of the explosive in the blast hole can indirectly obtain the depth of the explosive in the blast hole, in other words, the distance measuring sensor 20 can further measure the depth of the explosive, so that the accuracy of the depth control is better. In addition, the distance detected by the distance measuring sensor 20 cooperates with the clamping action of the cover plate, which can better assist the conveying pipe 40 to move to the position directly above the blast hole, that is, the shell of the device is preliminarily fixed on the conveying pipe 40 by using the clamping action of the cover plate, and then the position of the conveying pipe 40 can be better adjusted by the distance measuring action of the distance measuring sensor 20. In order to reduce the positioning error, a scale is arranged on the shell, which is located beside the cover plate, and the distance between the two cover plates after sliding to the center of the storage drum 2 is obtained through the scale, so as to adjust the cover plate, so that the distance between the two cover plates and the center of the conveying pipe 40 is the same, which cooperates with the distance measuring sensor 20 to realize accurate positioning, that is, through the above arrangement, the distance between all distance measuring sensors 20 and the center is the same, so that all distance measuring sensors 20 fall directly above the blast hole, which means that the conveying pipe 40 has been adjusted and positioned. In order to facilitate the fixation of the shell after the positioning of the conveying pipe 40, it is preferred that ground supporting legs 30 are detachably mounted around the shell 1, so that the shell can be stably kept in a relatively fixed state with the conveying pipe 40 by the supporting action of the ground supporting legs 30 on the ground. Further preferably, in order to better support the ground by the ground supporting legs 30, each ground supporting leg 30 is of a telescopic structure, so that the length of the ground supporting leg 30 can be adjusted according to the distance between the shell and the ground, so that all ground supporting legs 30 can support the ground.

[0058] In addition, in order to make the device suitable for blast holes of various diameters, each distance measuring sensor 20 is slidingly mounted on the bottom of the shell 1, and the sliding direction is the radial direction of the circle where the driving connection A part 5.2 is located, and the distance between the distance measuring sensor 20 and the center of the circle where the driving connection A part 5.2 is located is adjusted to adapt to different blast hole diameters.

[0059] Finally, it should be noted that the present application is also matched with a plurality of monitors, each of which is connected to the controller. The distance measured by the distance sensor 20 and the weight, charge amount and other parameters measured by the gravity sensor are obtained through the monitor. In this way, the construction personnel on the ground can obtain the charging condition through the display on the monitor, and the construction personnel responsible for controlling the delivery of the delivery pipeline 40 on the mixed explosive truck can also obtain the charging condition through the parameters displayed by the monitor, thereby facilitating the control of the delivery state of the delivery pipeline 40. In addition, each power module of the present application can be supported by the power provided by the mixed explosive truck, or can be supported by an additional power supply device, and is not specifically limited here. The rotary drive member includes a rotary motor 7.1 and a rotary transmission set 7.2. The rotary motor 7.1 is installed on the horizontal sliding member, and its output shaft is in transmission connection with the rotary shaft of the rotary plate through the rotary transmission set 7.2. The rotary transmission set 7.2 can be one or a combination of a gear set, a belt pulley assembly or a transmission chain assembly, and is not limited to a certain type. The horizontal sliding member includes a horizontal sliding plate 8 and a horizontal drive member 9. The rotary drive member and the rotary plate are installed on the horizontal sliding plate 8. The horizontal sliding plate 8 is slidingly installed on the housing 1 and slides relative to the housing 1 under the action of the horizontal drive member 9 to open the lower opening 1.2 and the bottom of the storage cylinder 2. The horizontal drive member 9 can be an electric push rod, an electric telescopic rod, a motor-screw rod assembly, two groups of reversible rope winding assemblies, a motor-rack and pinion assembly, etc.
