Description

Technical Field

[0001] This utility model belongs to the technical field of detonator safety assembly devices, and specifically relates to a device for preventing sympathetic detonation on a detonator assembly line. Background Technology

[0002] Electronic detonators are a new type of explosive device that uses electronic chip modules to replace traditional control methods. They feature high delay accuracy, ease of management and control, and convenient networking, representing an important direction for technological development in the civil explosives industry. During the production process, electronic detonators typically have protective structures installed at the collection and transfer windows of the assembly line to prevent propagation and sympathetic detonation.

[0003] While existing detonator assembly line anti-detonation devices can meet the basic requirement of flexibly opening and closing the transmission window of the assembly line to prevent detonation, the baffles used are adjusted by only telescopic push rods without auxiliary guide structures. This easily leads to poor stability of the vertical movement of the baffles and makes the telescopic push rods easily damaged by terrain deformation. Therefore, they cannot fully meet people's needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an anti-propagation sympathetic explosion device for detonator assembly lines. This device not only meets the basic requirement of protecting the transmission window of the assembly line from propagation sympathetic explosion, but also enables the protective structure and drive adjustment structure to have significant stability.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for preventing the propagation of detonation on a detonator assembly line, comprising a protective cylinder installed at the product collection and transfer window of the detonator assembly line, a linear slide table installed on the top of the side end of the protective cylinder, a vertical plate installed on the slide seat of the linear slide table, a support groove installed on the top of the side end of the protective cylinder, a support slider installed on the vertical plate and slidably connected to the support groove, a mounting plate installed on the vertical plate, a telescopic push rod installed vertically on the mounting plate, a protective cover installed at the lower end of the output shaft of the telescopic push rod and capable of engaging with the protective cylinder, a guide tube installed on the mounting plate, and a guide rod installed on the protective cover and engaging with the guide tube.

[0006] As a further improvement of this utility model, the protective cylinder is snapped into the collection and transfer window, and an extension ring plate is provided on the side end of the protective cylinder. The extension ring plate is provided with a fixing bolt for screwing and fixing the side end of the collection and transfer window, and a threaded fixing hole for screwing and fixing the fixing bolt is provided on the side end of the collection and transfer window.

[0007] As a further improvement of this utility model, a first compression washer is provided on the inner side wall of the extension ring plate, and the first compression ring plate is misaligned with the fixing bolt.

[0008] As a further improvement of this utility model, a second clamping washer adapted to the protective cylinder is provided on the side end of the protective cover. The second clamping washer can enhance the sealing performance at the connection between the protective cover and the protective cylinder.

[0009] As a further improvement of this utility model, both the sliding hole of the support groove and the vertical cross-section of the support slider are T-shaped. This can prevent the support slider from vertically shifting relative to the support groove, thereby better supporting and guiding the vertical plate, and preventing the linear slide table from easily deforming and being damaged due to bearing the lateral forces of the vertical plate and mounting plate alone.

[0010] As a further improvement of this utility model, a reinforcing inclined plate is provided between the mounting plate and the vertical plate. The addition of the reinforcing inclined plate between the mounting plate and the vertical plate effectively improves the bending resistance of the mounting plate under dynamic loads, prevents structural fatigue damage caused by repeated lifting and lowering movements, and extends the service life of the device.

[0011] As a further improvement of this utility model, the protective cover is provided with a first connecting cylinder that is snapped and fixed to the output shaft of the telescopic push rod. The first connecting cylinder is provided with a first connecting bolt for screwing the output shaft of the telescopic push rod, and the output shaft of the telescopic push rod is provided with a first threaded connection hole for screwing to the first connecting bolt. The protective cover is also provided with a second connecting cylinder that is snapped and fixed to the guide rod. The second connecting cylinder is provided with a second connecting bolt for screwing to the guide rod, and the guide rod is provided with a second threaded connection hole for screwing to the second connecting bolt. The output shaft of the telescopic push rod and the protective cover are detachably and securely connected by the first connecting cylinder and the first connecting bolt. The guide rod and the second connecting cylinder are also fixed by the second connecting bolt, which not only ensures the stability of the transmission connection, but also facilitates later disassembly, maintenance or replacement of parts, thus improving the maintainability of the equipment.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, by installing protective cylinders and liftable protective covers at the product collection and transfer windows of the detonator assembly line, the covers can be opened during normal transfer and closed quickly in case of abnormality or shutdown, physically isolating the transfer path and effectively preventing shock waves and debris from spreading to adjacent equipment or workstations in the event of an accidental explosion at a certain workstation, thus significantly improving the safety of the entire assembly line.

[0014] Secondly, the protective cover is driven vertically by a telescopic push rod, which, together with the guide tube and guide rod, forms a dual-point positioning support system to ensure that the protective cover runs smoothly and does not deviate during the lifting process. At the same time, the vertical plate is slidably connected to the support slide groove through the T-shaped structure support slider, which improves the lateral disturbance resistance, avoids structural loosening or jamming due to vibration, and enhances the rigidity and reliability of the overall device.

[0015] Third, the protective cylinder is pre-installed on the collection and transfer window by snap-fit, and is screwed to the threaded fixing hole on the side of the window by the fixing bolt on the extension ring plate, so as to achieve quick positioning and firm connection; the setting of the first pressure washer increases the friction of the contact surface and plays a buffering role, preventing the connection from loosening due to long-term vibration, and improving the durability and sealing of the installation.

[0016] Fourth, the protective cover is provided with a second compression washer that is compatible with the protective cylinder. When the protective cover falls and locks into place with the protective cylinder, the two are tightly fitted by the compression washer, which further blocks the propagation path of the explosion energy and improves the explosion-proof effect.

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 2As shown, an anti-detonation device for a detonator assembly line includes a protective cylinder 101 installed at the product collection and transfer window of the detonator assembly line. A linear slide 102 is provided on the top of the side end of the protective cylinder 101. A vertical plate 103 is provided on the slide seat of the linear slide 102. A support groove 104 is also provided on the top of the side end of the protective cylinder 101. A support slider 105 is provided on the vertical plate 103 and slidably connected to the support groove 104. An installation plate 106 is provided on the vertical plate 103. A telescopic push rod 107 is vertically provided on the installation plate 106. A protective cover 108 that can be engaged with the protective cylinder 101 is provided at the lower end of the output shaft of the telescopic push rod 107. A guide tube 109 is provided on the installation plate 106. A guide rod 110 that is engaged with the guide tube 109 is provided on the protective cover 108.

[0024] like Figure 1 , 3 As shown, the protective cylinder 101 is snapped into the collection and transfer window. An extension ring plate 111 is also provided on the side end of the protective cylinder 101. A fixing bolt 112 is provided on the extension ring plate 111 to fix the side end of the collection and transfer window. A threaded fixing hole is provided on the side end of the collection and transfer window to be screwed into the fixing bolt 112.

[0025] like Figure 3 As shown, a first compression washer 201 is provided on the inner side wall of the extension ring plate 111, and the first compression washer plate is misaligned with the fixing bolt 112. The first compression washer 201 can improve the sealing performance of the connection between the extension ring plate 111 and the side end of the collection and transfer window.

[0026] like Figure 2 As shown, a second compression washer 202 adapted to the protective cylinder 101 is provided on the side end of the protective cover 108. The second compression washer 202 can improve the sealing of the connection between the side end of the protective cover 108 and the protective cylinder 101.

[0027] like Figure 1 , 2 As shown in Figure 3, the sliding hole of the support groove 104 and the vertical section of the support slider 105 are both T-shaped, which can prevent the support slider 105 from vertically shifting relative to the support groove 104, thus giving the vertical plate 103 better stability.

[0028] like Figure 1 , 2 As shown, a reinforcing inclined plate 203 is provided between the mounting plate 106 and the vertical plate 103. The addition of the reinforcing inclined plate 203 between the mounting plate 106 and the vertical plate 103 effectively improves the bending resistance of the mounting plate 106 under dynamic loads, prevents structural fatigue damage caused by repeated lifting and lowering movements, and extends the service life of the device.

[0029] When detonator products need to be collected, the slide block of the linear slide table 102 is moved away from the collection and transfer window. Under the sliding cooperation of the support slider 105 and the support groove 104, the vertical plate 103, the mounting plate 106, the telescopic push rod 107, and the protective cover 108 are moved, causing the protective cover 108 to separate from the protective cylinder 101. Then, the output shaft of the telescopic push rod 107 can be shortened by a certain length. Under the vertical insertion guidance of the guide tube 109 and the guide rod 110, the protective cover 108 is stably lifted upward, causing it to be vertically misaligned with the protective cylinder 101. At this time, the collection and transfer window is in an open state, and the detonator products can smoothly enter and exit through the collection and transfer window and the protective cylinder 101 to complete the normal assembly flow.

[0030] After collecting the detonator products, the output axis of the telescopic push rod 107 can be extended downward by a certain length. With the vertical insertion of the guide rod 110 and the guide cylinder 109, the protective cover 108 is stably moved downward, so that the protective cover 108 moves to the side end of the protective cylinder 101. Then, the slide of the linear slide table 102 can be driven to move towards the collection and transfer window, so that the protective cover 108 and the protective cylinder 101 are locked together. The second pressure washer 202 provides a significant seal between the protective cover 108 and the protective cylinder 101. At this time, the second pressure washer 202 on the side end of the protective cover 108 is tightly fitted with the protective cylinder 101. At the same time, the first pressure washer 201 on the protective cylinder 101 also enhances the sealing of the connection, thus forming a physical explosion barrier in the transfer path, effectively blocking the propagation path of the explosion shock wave, high temperature gas and fragments, and preventing the "parasitic explosion" phenomenon from spreading to adjacent work positions.

[0031] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the protective cover 108 is provided with a first connecting cylinder 204 that is snapped and fixed to the output shaft of the telescopic push rod 107. The first connecting cylinder 204 is provided with a first connecting bolt 205 for screwing the output shaft of the telescopic push rod 107. The output shaft of the telescopic push rod 107 is provided with a first threaded connection hole for screwing the first connecting bolt 205. The protective cover 108 is also provided with a second connecting cylinder 206 that is snapped and fixed to the guide rod 110. The second connecting cylinder 206 is provided with a second connecting bolt 207 for screwing and fixing the guide rod 110. The guide rod 110 is provided with a second threaded connection hole for screwing the second connecting bolt 207.

[0032] Simply engage the output shaft of the telescopic push rod 107 with the first connecting cylinder 204, and then pass the first connecting bolt 205 through the side wall of the first connecting cylinder 204 and screw it into the first threaded connection hole to achieve flexible fixation between the output shaft of the telescopic push rod 107 and the first connecting cylinder 204. Similarly, simply engage the guide rod 110 with the second connecting cylinder 206, and then pass the second connecting bolt 207 through the side wall of the second connecting cylinder 206 and screw it into the second threaded connection hole to achieve flexible fixation between the guide rod 110 and the protective cover 108. When the protective cover 108 needs maintenance, simply separate the first connecting bolt 205 from the first threaded connection hole, release the fixation at the engagement point between the first connecting cylinder 204 and the output shaft of the telescopic push rod 107, and then separate the second connecting bolt 207 from the second threaded connection hole, releasing the fixation at the connection point between the second connecting cylinder 206 and the guide rod 110. Afterwards, the protective cover 108 and the second pressure washer 202 can be replaced.

[0033] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
