Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, specifically to a lifting device for sliding door maintenance. Background Technology

[0002] A sliding door is a type of car door that can be both pushed and pulled. It is widely used in transportation vehicles such as high-speed rail and subway. Depending on the driving method, sliding doors can be divided into types such as electro-pneumatic sliding doors and manual sliding doors. Sliding doors are also characterized by their complex structure and powerful functions, containing dozens of system devices such as control systems and locking systems.

[0003] Currently, when repairing damaged sliding doors, they need to be disassembled. During the disassembly process, jacks are used to lift them or personnel are used to manually lift them off. After the sliding door is lifted by the jacks, it still needs to be lifted down by personnel, which is time-consuming and laborious. Therefore, a lifting device for sliding door repair is proposed. A vacuum suction cup is attached to the sliding door, and air is supplied to the sleeve through a power component to move the support column upward, which can lift the sliding door. Moving this device can disassemble the sliding door. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a lifting device for repairing sliding doors. A vacuum suction cup is attached to the sliding door, and air is supplied to the sleeve through a power component to move the support column upward, thereby lifting the sliding door. Moving this device allows the sliding door to be disassembled.

[0005] The technical solution adopted by this utility model to solve its technical problem is a lifting device for repairing a sliding door, including a base plate, a lifting assembly provided on the top of the base plate, the lifting assembly including a sleeve fixed to the top of the base plate by a flange, a protective sleeve welded to the top of the sleeve, a support column sleeved through the inside of the protective sleeve, a first piston fixed to the bottom end of the support column inside the sleeve by bolts, and an adsorption assembly provided on the top of the support column.

[0006] The adsorption assembly includes a vacuum suction cup mounted on the top of a support column via a mounting bracket. One end of the vacuum suction cup is fixed with an air tube by bolts, and the other end of the vacuum suction cup is welded with an internal threaded sleeve. A long screw is threaded through the internal threaded sleeve, and one end of the long screw located inside the vacuum suction cup is connected to a second piston via a bearing.

[0007] By adopting the above technical solution, the rotating long screw drives the second piston to move, extracting the gas in the vacuum suction cup and making it firmly adsorbed on one side of the sliding door. The gas enters the sleeve and moves the sliding door held by the support column and vacuum suction cup upward through the first piston.

[0008] Specifically, a limiting groove is formed on one side of the inner side of the sheath, and a first piston is welded to one side of the support column. The first piston is located inside the sheath.

[0009] Specifically, the vacuum suction cup has exhaust holes at both ends of the top and bottom of the internal threaded sleeve.

[0010] Specifically, a power assembly is provided on the top of the base plate on one side of the sleeve. The power assembly includes an air pump mounted on the top of the base plate via a mounting bracket. The air outlet of the air pump is connected to a connecting hose via a pipe joint. One end of the connecting hose is connected to an air inlet check valve via a threaded groove. One end of the air inlet check valve is connected to an air inlet pipe via a threaded groove. One end of the air inlet pipe is connected to one side of the sleeve via a pipe joint.

[0011] Specifically, the air inlet of the air pump is connected to an air inlet filter via a threaded groove, an air outlet pipe is welded to the top of the air inlet pipe, and a solenoid valve is connected to the top of the air outlet pipe via a threaded groove.

[0012] Specifically, an energy storage box is embedded inside the base plate, and brakeable omnidirectional wheels are fixed at equal intervals at the bottom of the base plate by bolts.

[0013] The beneficial effects of this utility model are:

[0014] (1) The lifting device for repairing a sliding door described in this utility model uses an air pump to supply air to the sleeve through a connecting hose, an air inlet check valve and an air inlet pipe. The gas enters the sleeve and pushes the first piston and the support column to move upward, which in turn pushes the sliding door held by the vacuum suction cup to move upward and lift it up. After the sliding door is lifted, the base plate is moved and removed. The solenoid valve is opened so that the gas in the sleeve can be discharged through the air inlet pipe and the air outlet pipe, so that the sliding door held by the support column and the vacuum suction cup after moving upward can be moved down.

[0015] (2) The lifting device for repairing a sliding door described in this utility model moves the base plate to press the vacuum suction cup against one side of the sliding door, and rotates the long screw to drive the second piston to move inside the vacuum suction cup. The movement of the second piston extracts the gas inside the vacuum suction cup, so that it can be firmly adsorbed onto one side of the sliding door. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The vacuum suction cup is attached to the sliding door. Air is supplied to the sleeve via a power unit, causing the support column to move upwards, thus lifting the sliding door. Moving this device allows the sliding door to be removed. Figure 1-5 As shown, the present invention discloses a lifting device for repairing a sliding door, comprising a base plate 1, a lifting assembly 2 on the top of the base plate 1, the lifting assembly 2 comprising a sleeve 201 fixed to the top of the base plate 1 by a flange, a protective sleeve 204 welded to the top of the sleeve 201, a support column 202 sleeved through the protective sleeve 204, a first piston 203 fixed to the bottom of the support column 202 inside the sleeve 201 by bolts, and an adsorption assembly 4 provided at the top of the support column 202.

[0025] The adsorption assembly 4 includes a vacuum suction cup 401 mounted on the top of the support column 202 via a mounting bracket. One end of the vacuum suction cup 401 is fixed with an air tube 402 by bolts, and the other end of the vacuum suction cup 401 is welded with an internal threaded sleeve 403. A long screw 404 is sleeved through the internal threaded sleeve 403. One end of the long screw 404 located inside the vacuum suction cup 401 is connected to a second piston 405 via a bearing.

[0026] When in use, rotating the long screw 404 drives the second piston 405 to move, extracting the gas from the vacuum suction cup 401 and making it firmly adhere to one side of the sliding door. The gas enters the sleeve 201 and moves the sliding door held by the support column 202 and the vacuum suction cup 401 upward through the first piston 203.

[0027] For example, such as Figure 2 As shown, the present invention also includes a limiting groove 206 formed on one side of the inner side of the sheath 204, and a first piston 203 welded to one side of the support column 202, the first piston 203 being located inside the sheath 204.

[0028] When in use, the limiting strip 205 moves within the limiting groove 206 as the support column 202 moves up and down, which can prevent the support column 202 from rotating without affecting its up and down movement.

[0029] For example, such as Figure 4 As shown, the present invention also includes exhaust holes 406 at both ends of the vacuum suction cup 401 located at the top and bottom of the internal threaded sleeve 403.

[0030] When in use, as the second piston 405 moves within the vacuum suction cup 401, the gas is discharged through the exhaust port 406 to avoid affecting the movement of the second piston 405.

[0031] For example, such as Figure 1 , Figure 3 As shown, this utility model also includes a power assembly 3 on the top of the base plate 1 located on one side of the sleeve 201. The power assembly 3 includes an air pump 301 mounted on the top of the base plate 1 via a mounting bracket. The air outlet of the air pump 301 is connected to a connecting hose 302 via a pipe joint. One end of the connecting hose 302 is connected to an air inlet check valve 303 via a threaded groove. One end of the air inlet check valve 303 is connected to an air inlet pipe 304 via a threaded groove. One end of the air inlet pipe 304 is connected to one side of the sleeve 201 via a pipe joint.

[0032] When in use, the air pump 301 works to deliver external gas to the sleeve 201 through the connecting hose 302, the air inlet check valve 303 and the air inlet pipe 304.

[0033] For example, such as Figure 3 As shown, the present invention also includes an air inlet filter cover 307 connected to the air inlet end of the air pump 301 through a threaded groove, an air outlet pipe 305 welded to the top of the air inlet pipe 304, and a solenoid valve 306 connected to the top end of the air outlet pipe 305 through a threaded groove.

[0034] When in use, the intake filter cover 307 can prevent impurities in the external gas from being drawn into the suction pump 301. The solenoid valve 306 is opened to allow the gas in the sleeve 201 to be discharged through the intake pipe 304 and the exhaust pipe 305.

[0035] For example, such as Figure 1 , Figure 3As shown, the present invention also includes an energy storage box 5 embedded inside the base plate 1, and brakeable universal wheels 6 are fixed at equal intervals at the bottom of the base plate 1 by bolts.

[0036] During use, the battery box 5 can supply power to the air pump 301 and the solenoid valve 306, and the braked casters 6 facilitate the movement of this device.

[0037] When this utility model is in use, the personnel move the base plate 1 to press the vacuum suction cup 401 against one side of the sliding door, and rotate the long screw 404 to drive the second piston 405 to move inside the vacuum suction cup 401. The movement of the second piston 405 extracts the gas inside the vacuum suction cup 401, so that it can be firmly attached to one side of the sliding door.

[0038] When the vacuum pump 301 is turned on, external gas is drawn through the air intake filter cover 307 and delivered to the sleeve 201 through the connecting hose 302, the air intake check valve 303 and the air intake pipe 304. The gas enters the sleeve 201 and pushes the first piston 203 and the support column 202 to move upward. The upward movement of the support column 202 pushes the plug door held by the vacuum suction cup 401 to move upward, which can lift it up.

[0039] After the sliding door is lifted, move the base plate 1 to remove the sliding door. Open the solenoid valve 306 to allow the gas in the sleeve 201 to be discharged through the air inlet pipe 304 and the air outlet pipe 305, so that the sliding door held by the upward-moving support column 202 and the vacuum suction cup 401 can be moved downward.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
