Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment cylinder processing technology, and specifically relates to an opening device for processing chemical equipment cylinders. Background Technology

[0002] Chemical equipment typically requires drilling equipment during processing. However, existing drilling equipment often only presses down and fixes one side of the cylinder, not the other side simultaneously. This results in poor stability of the cylinder during the drilling process, making it prone to shaking or shifting, which in turn affects the effectiveness and efficiency of drilling the cylinder.

[0003] For example, the utility model patent with announcement number CN222830769U discloses a hole-opening device for processing the cylinder of chemical equipment. In the technical solution of this patent document, a fixed beam is fixedly connected to the left side of the base frame, a first electric push rod is fixedly connected to the bottom of the fixed beam, a stabilizing plate is fixedly connected to the bottom of the first electric push rod, and an anti-slip pad is fixedly connected to the bottom of the stabilizing plate. It can only press the cylinder from the left side and lacks a limiting and fixing mechanism for the right side of the cylinder. Therefore, during the hole-opening process, the cylinder is prone to displacement or shaking, which in turn affects the hole-opening process. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a hole-opening device for processing the cylinder of chemical equipment. This device not only meets the basic requirements for hole-opening processing of the cylinder, but also enables simultaneous fixation of the cylinder from both sides, thereby enhancing the stability of the cylinder and avoiding affecting the effect and efficiency of hole-opening processing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hole-opening device for processing the cylinder of chemical equipment, including a base, a placement groove with an arc-shaped inner wall provided on the base along the left and right direction by a support frame, a rotation drive module for rotating the cylinder provided on the base, a top plate provided on the base by a support rod, a movable hole-opening module provided on the top plate, a fixing frame provided on the left and right sides of the placement groove, a first telescopic push rod provided vertically on the fixing frame, and a pressure plate provided at the lower end of the output shaft of the first telescopic push rod.

[0006] As a further improvement of this utility model, the rotation drive module includes a mounting slot on the base and located inside the support groove along the front-rear direction. A bidirectional screw is rotatably mounted in the mounting slot. A first drive motor for rotating the first drive motor is mounted on the mounting slot. Mounting blocks that are slidably connected to the mounting slot are provided at both ends of the bidirectional screw. Mounting brackets located on both sides of the support groove are slidably mounted on the base. A rotating shaft is rotatably mounted on the mounting bracket. A drive roller is mounted on the rotating shaft. The drive roller is located above the central axis of the cylinder. A second drive motor for rotating the rotating shaft is mounted on one mounting bracket. A connecting plate is provided between the mounting block and the corresponding mounting bracket.

[0007] As a further improvement of this utility model, a guide slot is provided on the top of the fixing frame, and a guide plate that is inserted into the guide slot is provided on the pressure plate.

[0008] As a further improvement of this utility model, the movable hole-opening module includes a linear slide table arranged at the bottom of the top plate in the left-right direction, a second telescopic push rod vertically arranged on the slide seat of the linear slide table, an installation frame arranged on the output shaft of the second telescopic push rod, and a hole-opening drill arranged on the installation frame.

[0009] As a further improvement of this utility model, the bottom of the slide of the linear slide table is also provided with a guide tube, and a guide rod is inserted into the guide tube on the mounting frame.

[0010] As a further improvement of this utility model, a connecting slide rail is provided on the base, and a connecting slide hole is provided on the mounting bracket to be slidably connected to the connecting slide rail.

[0011] As a further improvement of this utility model, an extension plate is also provided at the bottom side of the base, and anchor bolts for connecting to the ground are provided on the extension plate. The extension plate and anchor bolts at the bottom of the base provide a stable foundation fixing function, preventing the device from shifting or vibrating during operation.

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

[0013] Firstly, fixed frames are provided on the left and right sides of the placement slot, which, together with the first telescopic push rod and the pressure plate, can clamp and fix the cylinder from both sides simultaneously, thereby enhancing stability and avoiding the impact of cylinder shaking on the opening accuracy and efficiency.

[0014] Secondly, the rotation drive module adopts a linkage mechanism of bidirectional screw, mounting block and connecting plate, which can be adaptively adjusted according to the size of the cylinder. At the same time, the first drive motor drives the drive roller to achieve smooth rotation of the cylinder to meet the requirements of multi-angle opening.

[0015] Thirdly, the movable hole-making module includes a linear slide, a second telescopic push rod, a mounting frame, and a hole-making drill, which allows the hole-making drill to move in the left and right directions on the top plate, further expanding the adjustment range of the hole-making position and improving its applicability.

Detailed Implementation

[0023] 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.

[0024] like Figure 1As shown, an opening device for processing the cylinder of chemical equipment includes a base 101. A placement groove 102 with an arc-shaped inner wall is provided on the base 101 along the left and right direction via a support frame 110. A rotation drive module for rotating the cylinder is also provided on the base 101. A top plate 103 is provided on the base 101 via a support rod 104. A movable opening module is provided on the top plate 103. U-shaped fixing frames 105 are respectively provided on the left and right sides of the placement groove 102. A first telescopic push rod 106 is vertically provided on the fixing frame 105. A pressure plate 107 is provided at the lower end of the output shaft of the first telescopic push rod 106.

[0025] like Figure 1 , 4 As shown in Figure 5, the rotation drive module includes a mounting slot 201 located on the base 101 along the front-rear direction and inside the support slot. A bidirectional screw 202 is rotatably mounted in the mounting slot 201. A first drive motor 203 for rotating the first drive motor 203 is mounted on the mounting slot 201. Mounting blocks 204 that are slidably connected to the mounting slot 201 are provided at both ends of the bidirectional screw 202. Mounting brackets 205 located on both sides of the support slot are slidably mounted on the base 101. A rotating shaft 206 is rotatably mounted on the mounting bracket 205 via a bearing 214. A drive roller 207 is mounted on the rotating shaft 206. The drive roller 207 is located above the central axis of the cylinder, thereby effectively preventing the bottom of the cylinder from disengaging from the placement slot 102 when the cylinder is rotated for adjustment. A second drive motor 208 for rotating the rotating shaft 206 is provided on one mounting bracket 205. A connecting plate 209 is provided between the mounting block 204 and the corresponding mounting bracket 205.

[0026] like Figure 1 As shown, the top of the fixing bracket 105 is also provided with a guide slot 210, and the clamping plate 107 is provided with a guide plate 211 that is inserted into the guide slot 210.

[0027] like Figure 1 , 3 As shown, the movable drilling module includes a linear slide 301 arranged at the bottom of the top plate 103 in the left-right direction. A second telescopic push rod 302 is vertically arranged on the slide of the linear slide 301. A mounting frame 303 is arranged on the output shaft of the second telescopic push rod 302. A drilling machine 304 is arranged on the mounting frame 303.

[0028] The worker places the cylinder to be processed in the arc-shaped placement groove 102 on the support frame 110. The arc-shaped inner wall can fit the outer surface of the cylinder, providing initial stable support. The first telescopic push rod 106 on the two side fixing frames 105 is activated, causing the clamping plate 107 to move downward. The guide plate 211 on the clamping plate 107 is inserted into the guide slot 210 at the top of the fixing frame 105 to ensure that the clamping process is smooth and without deviation. The clamping plate 107 applies uniform pressure to the cylinder from both sides to achieve synchronous clamping and improve the stability of the cylinder.

[0029] Then the drilling machine 304 can be started, and the horizontal position of the drilling machine 304 in the left and right directions can be adjusted by moving the slide of the linear slide table 301 left and right. The vertical position of the drilling machine 304 can be adjusted by extending and retracting the output shaft of the second telescopic push rod 302, so that the drilling machine 304 can perform drilling on the corresponding position of the top of the cylinder.

[0030] Then, the first telescopic push rod 106 can be driven to shorten its length upwards by a certain amount, causing the pressure plate 107 to move upwards by a certain distance, thus releasing the downward pressure on the cylinder. Subsequently, the first drive motor 203 is started to drive the bidirectional screw 202 to rotate, adjusting the distance between the mounting blocks 204 on both sides. The mounting brackets 205 and drive balls on both sides are moved and adjusted through the connecting plate 209, so that the drive rollers 207 on both sides abut against the corresponding side ends of the cylinder. Then, the second drive motor 208 can be started to drive the rotating shaft 206 and drive roller 207 on one side to rotate. Under the support of the placement groove 102 and the limiting effect of the drive roller 207 on the other side, the rotation angle of the cylinder is adjusted according to the required opening position, so that the target position is directly facing the drilling machine 304. Then, the new position of the cylinder can be opened.

[0031] After the opening process of the cylinder is completed, the output axis of the first telescopic push rod 106 can be driven again to shorten by a certain length, so that the clamping plate 107 moves upward, releasing the cylinder and taking the cylinder with the opening completed out of the placement slot 102 for subsequent processing, cleaning metal debris and dust on the device; checking whether each moving part is normal, lubricating the transmission part to ensure smooth use next time.

[0032] To achieve functions such as automatic positioning, automatic rotation, and automatic hole drilling, and further improve processing efficiency and accuracy, a PLC control system or CNC system is configured. This is a common technical approach in this field and will not be elaborated here.

[0033] According to another embodiment of the present invention, such as Figure 1 , 3As shown, the bottom of the slide block of the linear slide table 301 is also provided with a guide sleeve 305, and a guide rod 306 is inserted into the guide sleeve 305 on the mounting frame 303. Through the insertion and cooperation of the guide sleeve 305 and the guide rod 306, the mounting frame 303 and the drilling machine 304 can move vertically stably, and the second telescopic push rod 302 can be easily damaged by terrain deformation during the operation of the drilling machine 304.

[0034] According to another embodiment of the present invention, such as Figure 4 , 5 As shown, a connecting slide rail 212 is provided on the base 101, and a connecting slide hole 213 is provided on the mounting bracket 205 to be slidably connected to the connecting slide rail 212. Through the sliding engagement of the connecting slide rail 212 and the connecting slide hole 213, the mounting bracket 205 can be stably slid back and forth relative to the base 101.

[0035] According to another embodiment of the present invention, such as Figure 2 As shown, an extension plate 108 is also provided at the bottom side of the base 101, and an anchor bolt 109 for connecting to the ground is also provided on the extension plate 108. The extension plate 108 and the anchor bolt 109 at the bottom of the base 101 provide a stable foundation fixing function to prevent displacement or vibration of the device during operation. After the device is placed in a suitable working position, the anchor bolt 109 can pass through the extension plate 108 and connect to the threaded connecting sleeve in the ground to prevent displacement or vibration during processing.

[0036] 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.
