Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinders for emergency doors, and in particular to a fixing mechanism for the disassembly and connection of a hydraulic cylinder for an emergency door. Background Technology

[0002] In modern industrial production and various engineering facilities, the hydraulic cylinder for emergency doors is a key component, bearing the important responsibility of controlling the opening and closing of emergency doors. Its operational stability directly affects the safety and normal operation of the entire system. When the hydraulic cylinder for emergency doors needs maintenance, repair, or component replacement, the disassembly of the hydraulic cylinder connection becomes an extremely important and challenging task.

[0003] The existing dismantling device (the fixed frame that supports the hydraulic cylinder during dismantling) is in use. The hydraulic cylinder is placed on the fixed seat of the dismantling device, which will generate a certain impact force. This impact force acts directly on the dismantling device and will cause some damage to the dismantling device, thus creating a certain safety risk when the dismantling device is used. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a fixing mechanism for the disassembly connection of the hydraulic cylinder of the emergency door, which can avoid rigid collision between the hydraulic cylinder and the device, prevent the threaded or pin connection parts from being deformed, damaged or loosened due to impact, and significantly improve the safety of the disassembly process and the reliability of the connection structure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An emergency door hydraulic cylinder disassembly connection fixing mechanism includes a base, the lower end of which is connected to a damping plate via a buffer assembly; a fixing plate is fixed to the upper end of the base, positioning plates are installed on both sides of the fixing plate, and a clamping assembly is arranged between the two positioning plates to clamp the emergency door hydraulic cylinder.

[0006] The buffer assembly includes multiple sliding rods distributed circumferentially along the base. Each sliding rod passes freely through the base, with a limit block fixed at the upper end of the sliding rod on the base, a buffer spring sleeved at the lower end of the sliding rod on the base, and the bottom end of the sliding rod fixed to a damping plate.

[0007] The clamping components are in two sets, and are arranged in a mirror-symmetrical manner on the left and right sides.

[0008] Each clamping assembly includes a threaded rod that is threadedly connected to the positioning plate. The outer end of the threaded rod is fixed with a handle, and the inner end of the threaded rod is rotatably connected to the clamping plate.

[0009] Each clamping plate has a movable rod fixed to the left and right sides at the bottom, and the movable rod slides in conjunction with the groove on the guide block.

[0010] The clamping plate is an arc-shaped plate, and a protective pad is fixedly connected to the inner side of each clamping plate.

[0011] A connecting plate is arranged between the fixed plate and the positioning plate. The mounting shaft passes through the fixed plate, the connecting plate, and the positioning plate and is locked with a nut.

[0012] Both sets of connecting plates have positioning rods fixedly connected to their bottom surfaces. The positioning rods are equipped with baffles on the front and rear sides of the positioning plates via positioning bolts. The baffles are in contact with the sides of the positioning plates.

[0013] The baffle is L-shaped, and a reinforcing bar is installed at the corner of the baffle.

[0014] A guide rod is fixed on the base, and the positioning rod passes through the corresponding vertical guide rod and is fixed by the upper and lower nuts.

[0015] This utility model provides a fixing mechanism for the disassembly and connection of the hydraulic cylinder of an emergency door, which has the following technical effects: 1) By setting up a buffer component, when the emergency door hydraulic cylinder is placed on this device during use, the hydraulic cylinder squeezes the device. At this time, the base slides on the sliding rod and squeezes the buffer spring. The buffer spring will generate a certain deformation when squeezed. The deformation of the buffer spring absorbs the impact force, so that the instantaneous impact load on the connection is effectively dispersed and reduced, thereby avoiding rigid collision between the emergency door hydraulic cylinder and this device, preventing the threaded or pin connection parts from being deformed, damaged or loosened due to impact, and significantly improving the safety of the disassembly process and the reliability of the connection structure.

[0016] 2) By using the clamping assembly, rotating the handle during operation causes the threaded rod to rotate, which in turn moves the clamping plate. The clamping plate clamps and fixes the hydraulic cylinder, ensuring stable positioning of the hydraulic cylinder during disassembly or maintenance. This prevents the connection from shifting or shaking due to uneven force or external forces, avoids damage to seals or deformation of the interface, and ensures the structural integrity of the hydraulic cylinder disassembly connection and the accuracy of subsequent hoisting.

Detailed Implementation

[0022] like Figure 1-4 As shown, a fixing mechanism for the disassembly connection of an emergency door hydraulic cylinder includes a base 1, which is connected to a damping plate 16 via a buffer assembly 2. The buffer assembly 2 reduces the impact of the emergency door hydraulic cylinder and other components on the device. A fixing plate 3 is fixed in the inner countersunk hole of the base 1, and positioning plates 5 are installed on the left and right sides of the upper end of the fixing plate 3. A clamping assembly 6 is installed between the two sets of positioning plates 5 to clamp the hydraulic cylinder and other components.

[0023] The buffer assembly 2 includes multiple sliding rods 201 distributed circumferentially along the base 1. Each sliding rod 201 passes vertically downward through a through hole on the edge of the base 1. A limit block 203 is fixed to the upper end of the sliding rod 201 on the base 1. A buffer spring 202 is fitted onto the portion of the sliding rod 201 below the base 1, and the lower end of the sliding rod 201 is fixed to a damping plate 16. The damping plate 16 and the buffer assembly 2 effectively reduce the impact force exerted on the device by the hydraulic cylinder of the emergency door.

[0024] The clamping components 6 consist of two sets, arranged symmetrically in a mirror image. Each set of clamping components 6 includes a threaded rod 601, which is threadedly connected to the positioning plate 5. A handle 602 is fixed to the outer end of the threaded rod 601, and a clamping plate 603 is rotatably connected to the inner end of the threaded rod 601. Both the left and right clamping plates 603 are arc-shaped, which can clamp the hydraulic cylinder of the emergency door, etc.

[0025] Preferably, a movable rod 7 is fixedly connected to the bottom surface of each clamping plate 603. The movable rod 7 slides in engagement with the groove on the guide block 8, and the groove is aligned with the axial direction of the threaded rod 601. The guide block 8 is fixedly connected to the positioning plate 5 by bolts. By setting the guide block 8 and the movable rod 7, the clamping plate 603 is guided.

[0026] Preferably, a protective pad 9, made of rubber, is fixedly connected to the surface of each clamping plate 603 that contacts the hydraulic cylinder of the emergency door, etc. The protective pad 9 protects the hydraulic cylinder of the emergency door and other components, preventing scratches.

[0027] Preferably, the guide block 8 has a countersunk hole at its center, which matches the diameter of one end of the emergency door hydraulic cylinder. After the emergency door hydraulic cylinder is inserted into the countersunk hole for positioning, it is then clamped left and right by the clamping assembly 6 to ensure that the emergency door hydraulic cylinder is vertically stable.

[0028] Preferably, connecting plates 4 are arranged on the left and right sides of the fixing plate 3, and a positioning rod 10 is fixedly connected to the lower end of each connecting plate 4. The fixing plate 3, connecting plate 4 and positioning plate 5 are all equipped with through holes. A mounting shaft 17 is inserted into the corresponding through hole. One end of the mounting shaft 17 is equipped with a limit plate, and the threaded section of the other end of the mounting shaft 17 is used for threaded connection with a nut. The mounting shaft 17 passes laterally through the two positioning plates 5, the two connecting plates 4 and the fixing plate 3 and is then locked by a nut.

[0029] Both sets of positioning rods 10 have L-shaped baffles 12 attached to their top surfaces. The sides of the baffles 12 contact the sides of the positioning plates 5. The baffles 12 are fixed to the positioning rods 10 by positioning bolts 13 and nuts 15. The baffles 12 limit the positioning plates 5 and prevent them from swinging around the mounting shaft 17.

[0030] Preferably, guide rods 11 are symmetrically fixed on the base 1, passing through the positioning rod 10 and secured with nuts. The guide rods 11 serve to fix the positioning rod 10.

[0031] Preferably, reinforcing ribs 14 are fixedly connected to the top surface of both sets of baffles 12. This improves the strength of the baffles 12.

[0032] Working principle and process: 1) During use, when the emergency door hydraulic cylinder is placed on this device, the hydraulic cylinder presses against the device. At this time, the base 1 slides on the sliding rod 201 and presses against the buffer spring 202. The buffer spring 202 will deform to a certain extent when it is pressed. The deformation of the buffer spring 202 absorbs the impact force, so that the instantaneous impact load on the connection is effectively dispersed and reduced, thereby avoiding rigid collision between the hydraulic cylinder and the device, preventing the threaded or pin connection parts from being deformed, damaged or loosened due to impact, and significantly improving the safety of the disassembly process and the reliability of the connection structure.

[0033] 2) During use, rotating the handle 602 causes the threaded rod 601 to rotate, which in turn moves the clamping plate 603. The clamping plate 603 clamps and fixes one end of the hydraulic cylinder, ensuring stable positioning during disassembly or maintenance. This prevents misalignment or shaking at the connection due to uneven force or external forces, avoids damage to seals or deformation of the interface, and ensures the structural integrity of the connection point for disassembling the emergency door hydraulic cylinder and the accuracy of subsequent hoisting.
