Description

Technical Field

[0001] This application relates to the field of fire extinguisher maintenance technology, specifically to an auxiliary device for the maintenance of fire extinguisher cylinders. Background Technology

[0002] Fire extinguishers need to be inspected and maintained regularly to prevent gaps from appearing at the welding points over time. To ensure the safety of fire extinguishers, air tightness tests are conducted. However, current air tightness testing devices on the market use a method of squeezing and fixing both ends of the fire extinguisher cylinder, which requires two people to work together during installation and removal, making it time-consuming and labor-intensive.

[0003] Therefore, it is necessary to provide an auxiliary device for the maintenance of fire extinguisher cylinders to solve the above problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an auxiliary device for the maintenance of fire extinguisher cylinders, which achieves the effect of easy loading and unloading by one person, saving time and effort.

[0006] The technical solution adopted by this application to solve its technical problem is: a fire extinguisher cylinder maintenance auxiliary device, including a support frame and a clamping assembly installed inside the support frame; the support frame includes two horizontal beams and two vertical beams; the vertical beams are vertically arranged between the two horizontal beams and are parallel and spaced apart; the two horizontal beams are arranged in parallel, and the horizontal beams and vertical beams form a rectangular frame; the support frame is vertically arranged, and a locking assembly is installed on the vertical beam; one end of the clamping assembly is fixedly connected to the upper horizontal beam, and the clamping assembly is vertically arranged and intersects the long side of the horizontal beam perpendicularly;

[0007] The clamping assembly includes a connecting seat, two clamping arms, and a locking frame. One end of the connecting seat is fixedly connected to the corresponding crossbeam. The connecting seat is located between the two clamping arms and is hinged. The two clamping arms are arranged opposite each other, and the plane of the clamping arms intersects the long side of the crossbeam perpendicularly. The locking frame is movably sleeved on the two clamping arms. Thus, the inspector places the fire extinguisher cylinder between the two clamping arms, with the cylinder's axis parallel to the crossbeam and the cylinder's diameter line intersecting the clamping arms. By lowering the locking frame, the two clamping arms are brought together to clamp the cylinder. Then, the locking frame is tightened, and the locking assembly is controlled to lock both ends of the cylinder.

[0008] Furthermore, the clamping arm is curved; thus, the inner wall of the clamping arm has more contact with the cylinder, thereby increasing the clamping friction on the cylinder and ensuring the stability of the clamping.

[0009] Furthermore, a cylindrical component is fixedly installed at the end of the clamping arm away from the connecting seat, and the axis of the cylindrical component is parallel to the long side of the crossbeam; thereby, the cylindrical component reduces the amplitude of the shaking at both ends of the fire extinguisher cylinder, so that the cylinder is in a horizontal state, which makes it easier for the inspection personnel to lock the cylinder later.

[0010] Furthermore, the locking frame includes rod one and rod two; the clamping arm is located between rod one and rod two, and the two ends of rod one and rod two are located on the outside of the clamping arm and are connected by bolts; thus, rod one and rod two move on the vertical plane where the clamping arm is located, and the clamping arm is controlled to close by bolts; the bolts and nuts are used to clamp rod one and rod two together with the clamping arm, thereby locking the clamping arm by the locking frame.

[0011] Furthermore, the locking assembly includes a pipe joint and a base, which are arranged opposite to each other; the pipe joint is located at one of the vertical beams, the axis of the pipe joint is perpendicular to the long side of the vertical beam, and the end of the pipe joint away from the base passes through the corresponding vertical beam and is connected to a high-pressure gas cylinder through a pipe;

[0012] The base is movably mounted on another vertical beam, with a through hole corresponding to the vertical beam. The base includes a tray, a support rod, and a locking nut. The tray is located inside the vertical beam and is fixedly installed to one end of the support rod. The axis of the support rod is on the same straight line as the axis of the pipe joint. The end of the support rod away from the tray passes through the through hole and is threadedly connected to the locking nut. Thus, the inspector aligns the gas cylinder inlet with the pipe joint, then pushes the support rod to make the tray press against the bottom of the gas cylinder, and tightens the locking nut to fix the gas cylinder in place.

[0013] Furthermore, a pneumatically controlled telescopic rod is fixedly connected to the top of the crossbeam connected to the connecting seat, and a robotic arm is connected to the end of the pneumatically controlled telescopic rod away from the crossbeam; thus, the pneumatically controlled telescopic rod controls the up and down movement of the support frame, thereby realizing the airtightness detection action; the robotic arm controls the lateral movement of the whole, which facilitates loading and unloading by the testing personnel.

[0014] The beneficial effects of this application are as follows: The fire extinguisher cylinder maintenance auxiliary device provided by this application, by setting up a clamping component, allows the inspector to place the fire extinguisher cylinder between two clamping arms; by lowering the locking frame, the two clamping arms are brought together to clamp the cylinder, and then the locking frame is tightened. Subsequently, the locking component is controlled to lock both ends of the cylinder. Thus, one person can install the fire extinguisher, saving manpower. The clamping component assists in the installation, replacing manual lifting, which shortens the installation time and achieves the effect of saving effort and time.

[0015] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be referred to below. Figures 1-3 This application will be described in further detail. Attached Figure Description

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figures 1-3 As shown, this application provides an auxiliary device for fire extinguisher cylinder maintenance, used in fire extinguisher airtightness testing, including a support frame and a clamping assembly installed inside the support frame; see reference. Figures 1-2 The support frame includes two horizontal beams 11 and two vertical beams 12; the vertical beams 12 are vertically arranged between the two horizontal beams 11 and are parallel and spaced apart; the two horizontal beams 11 are arranged in parallel, and the horizontal beams 11 and the vertical beams 12 form a rectangular frame. The support frame is vertically arranged, and a locking component 13 is installed on the vertical beams 12; one end of the clamping component is fixedly connected to the upper horizontal beam 11, the clamping component is vertically arranged, and intersects the long side of the horizontal beam 11 perpendicularly.

[0025] Reference Figure 1 , Figure 3 The clamping assembly includes a connecting seat 21, two clamping arms 22, and a locking frame 23. One end of the connecting seat 21 is fixedly connected to the corresponding crossbeam 11. The connecting seat 21 is located between the two clamping arms 22 and is hinged together. The two clamping arms 22 are arranged opposite to each other, and the plane of the clamping arms 22 intersects the long side of the crossbeam 11 perpendicularly. The locking frame 23 is movably sleeved on the two clamping arms 22. Thus, the inspector places the fire extinguisher cylinder between the two clamping arms 22, with the cylinder's axis parallel to the crossbeam 11 and the cylinder's diameter line intersecting the clamping arms 22 (see reference). Figure 1 The locking frame 23 is lowered so that the two clamping arms 22 come together to clamp the cylinder. Then the locking frame 23 is tightened, and then the locking assembly 13 is controlled to lock the two ends of the cylinder.

[0026] Among them, the clamping arm 22 is curved; thus, the inner wall of the clamping arm 22 has more contact with the gas cylinder, thereby increasing the clamping friction on the gas cylinder and ensuring the stability of the clamping.

[0027] A cylindrical component 221 is fixedly installed at the end of the clamping arm 22 away from the connecting seat 21. The axis of the cylindrical component 221 is parallel to the long side of the crossbeam 11. Thus, the cylindrical component 221 reduces the amplitude of the shaking at both ends of the fire extinguisher cylinder, so that the cylinder is in a horizontal state, which makes it easier for the inspection personnel to lock the cylinder later.

[0028] The locking frame 23 includes a first rod 231 and a second rod 232; the clamping arm 22 is located between the first rod 231 and the second rod 232, with the two ends of the first rod 231 and the second rod 232 located on the outside of the clamping arm 22 and connected by bolts; thus, the first rod 231 and the second rod 232 move on the vertical plane where the clamping arm 22 is located, and the clamping arm 22 is controlled to close by bolts; the first rod 231 and the second rod 232 clamp the clamping arm 22 by bolts and nuts, thereby locking the clamping arm 22 by the locking frame 23.

[0029] Reference Figure 2 The locking component 13 includes a pipe joint 131 and a base 132, which are arranged opposite to each other. The pipe joint 131 is located at one of the vertical beams 12, and the axis of the pipe joint 131 is perpendicular to the long side of the vertical beam 12. The end of the pipe joint 131 away from the base 132 passes through the corresponding vertical beam 12 and is connected to a high-pressure gas cylinder through a pipe.

[0030] The base 132 is movably mounted on another vertical beam 12, with a through hole corresponding to the vertical beam 12. The base 132 includes a tray 1321, a support rod 1322, and a locking nut 1323. The tray 1321 is located inside the vertical beam 12 and is fixedly installed with one end of the support rod 1322. The axis of the support rod 1322 is on the same straight line as the axis of the pipe joint 131. The end of the support rod 1322 away from the tray 1321 passes through the through hole and is threadedly connected to the locking nut 1323. Thus, the inspector aligns the gas cylinder inlet with the pipe joint 131, then pushes the support rod 1322 so that the tray 1321 abuts against the bottom of the gas cylinder, and tightens the locking nut 1323, thereby fixing the gas cylinder.

[0031] In addition, a pneumatic telescopic rod is fixedly connected to the top of the crossbeam 11 connected to the connecting seat 21, and a robotic arm is connected to the end of the pneumatic telescopic rod away from the crossbeam 11; thus, the pneumatic telescopic rod controls the up and down movement of the support frame, thereby realizing the airtightness detection action; the robotic arm controls the lateral movement of the whole, which is convenient for the inspection personnel to load and unload.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
