Description

Technical Field

[0001] This utility model relates to the field of freight elevator balance lock technology, and in particular to a self-locking anti-fall type freight elevator balance lock device. Background Technology

[0002] A balance lock is an auxiliary tool for suspending heavy production equipment. It is used by personnel performing continuous, repetitive tasks on the production line for suspending, concentrating, moving, and removing tools. It is easy to operate with pneumatic, electrical, and hydraulic tools. Balancers are mostly used inside freight elevators, and balance locks place extremely high demands on the elevators, ensuring safety within them. Therefore, balance locks play a crucial role in the operation of freight elevators.

[0003] Patent application CN222410604U discloses an improved freight elevator balance lock. It includes a contact seat, a mounting plate, and a protective sleeve mounted on the mounting plate. The protective sleeve has a movable cavity containing a support shaft. A drive device for driving the support shaft is located on the side of the protective sleeve away from the movable cavity. The contact seat includes a base, with a left limiting plate and a right limiting plate on both sides of the top of the base. One end of the support shaft extending out of the movable cavity is limited by the left and right limiting plates. This invention limits the support shaft to an arc-shaped plate between the left and right limiting plates. Under the action of a compression spring, gravity controls the left and right limiting plates and the arc-shaped plate to limit its movement, effectively improving the stability of the freight elevator. Simultaneously, the compression spring buffers the support shaft, preventing damage from a large impact force when the freight elevator falls rapidly, thus avoiding potential safety accidents.

[0004] However, the outer casing of this balance lock is not convenient to disassemble quickly, which may lead to disassembly difficulties during maintenance. Maintenance personnel may need to spend more time and effort on routine inspections and repairs, which will increase labor costs. During maintenance and repair, the freight elevator may need to be shut down for a long time, which will affect the efficiency of cargo transportation and may cause economic losses. To address the above problems, we have launched a self-locking anti-fall freight elevator balance lock device. Utility Model Content

[0005] This utility model discloses a self-locking anti-fall type freight elevator balance lock device. It studies and improves the existing structure and its shortcomings, and provides a self-locking anti-fall type freight elevator balance lock device to achieve better practical value.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-locking anti-fall type freight elevator balance lock device includes a mounting plate, a first inner plate fixedly connected to one side of the mounting plate, a shell slidably connected to the outer side of the first inner plate, a second inner plate fixedly connected to the inside of the shell, an electric push rod and a support shaft respectively disposed between the interior of the first inner plate and the second inner plate, a balance lock rod fixedly connected to the bottom of the support shaft, and a fixing component disposed between the mounting plate and the shell for fixing the shell;

[0008] The fixing component includes a receiving groove, which is equidistantly opened on one side of the mounting plate. A slider is slidably connected inside the receiving groove. A connecting block is fixedly connected to one side of the slider. A first spring is provided between one side of the slider and one side of the inner wall of the receiving groove. A first slot is opened on the top of the connecting block.

[0009] In a preferred embodiment, a housing is fixedly connected to the top of the outer shell, a first insert block is slidably connected to the inside of the housing, a first mounting rod is fixedly connected to the top of the first insert block, the outer side of the first mounting rod is slidably connected to the inside of the housing, a second spring is provided on the outer side of the first mounting rod, and the outer side of the first insert block is slidably connected to the inside of the first slot.

[0010] In a preferred embodiment, a fixing block is fixedly connected to the top of the outer casing, a second mounting rod is slidably connected inside the fixing block, a slide plate is fixedly connected to one end of the second mounting rod, the bottom of the slide plate is slidably connected to the top of the outer casing, a second insert block is fixedly connected to one side of the slide plate, and a third spring is provided on the outside of the second mounting rod.

[0011] In a preferred embodiment, a second slot is provided on one side of the connecting block, and a third slot is provided on one side of the first insert block. The second insert block is slidably connected to the interior of the second slot and the interior of the third slot, respectively.

[0012] In a preferred embodiment, a positioning block is fixedly connected at equal intervals to one side of the mounting plate, and the interior of the positioning block is slidably connected to the exterior of the outer shell.

[0013] In a preferred embodiment, sealing strips are fixedly connected to one side of both the first inner plate and the second inner plate.

[0014] The self-locking anti-fall type freight elevator balance lock device provided by this utility model has the following advantages:

[0015] Firstly, pulling the first mounting rod upwards compresses the second spring, allowing the first insert to enter the housing, and the connecting block to also enter the housing. After releasing the first mounting rod, the first insert is pushed into the first slot by the force of the second spring, thus fixing the housing to the mounting plate.

[0016] Secondly, by using the operation of the second mounting rod and with the help of the third spring, the second insert block is smoothly passed through the second and third slots and abuts against the inner wall of the first slot, while restricting the connecting block and the first insert block. This step further enhances the fixing effect.

[0017] Thirdly, the design of the fixed components and pull-mounting rod makes the disassembly of the balance lock housing simpler and faster. When the balance lock malfunctions, quick disassembly allows maintenance personnel to rapidly inspect the internal components, promptly identify and resolve problems, and reduce the impact of the malfunction on the operation of the freight elevator. This fixed structure reduces the time spent by maintenance personnel during maintenance, improving work efficiency. Attached Figure Description

[0026] The self-locking anti-fall type freight elevator balance lock device disclosed in this utility model is mainly used in freight elevator balance lock scenarios.

[0027] Reference Figures 1 to 6 A self-locking anti-fall type freight elevator balance lock device includes: a mounting plate 1, a first inner plate 2 fixedly connected to one side of the mounting plate 1, a shell 3 slidably connected to the outer side of the first inner plate 2, a second inner plate 4 fixedly connected to the inside of the shell 3, an electric push rod 5 and a support shaft 6 respectively provided between the interior of the first inner plate 2 and the second inner plate 4, a balance lock rod 7 fixedly connected to the bottom of the support shaft 6, and a fixing component provided between the mounting plate 1 and the shell 3 for fixing the shell 3;

[0028] The fixing component includes a receiving groove 9, which is equidistantly opened on one side of the mounting plate 1. A slider 10 is slidably connected inside the receiving groove 9. A connecting block 11 is fixedly connected to one side of the slider 10. A first spring 12 is provided between one side of the slider 10 and one side of the inner wall of the receiving groove 9. A first slot 13 is opened on the top of the connecting block 11.

[0029] The top of the outer casing 3 is fixedly connected to the casing 14, the inside of the casing 14 is slidably connected to the first insert block 15, the top of the first insert block 15 is fixedly connected to the first mounting rod 16, the outside of the first mounting rod 16 is slidably connected to the inside of the casing 14, the outside of the first mounting rod 16 is provided with the second spring 17, and the outside of the first insert block 15 is slidably connected to the inside of the first slot 13.

[0030] A fixing block 18 is fixedly connected to the top of the outer casing 3. A second mounting rod 19 is slidably connected inside the fixing block 18. A slide plate 20 is fixedly connected to one end of the second mounting rod 19. The bottom of the slide plate 20 is slidably connected to the top of the outer casing 3. A second insert block 21 is fixedly connected to one side of the slide plate 20. A third spring 22 is provided on the outside of the second mounting rod 19.

[0031] A second slot 23 is provided on one side of the connecting block 11, and a third slot 24 is provided on one side of the first insert block 15. The second insert block 21 is slidably connected to the interior of the second slot 23 and the interior of the third slot 24, respectively.

[0032] In the above technical solution, considering that the outer shell of the balance lock is not convenient to disassemble quickly, it may cause disassembly difficulties during maintenance. Maintenance personnel may need to spend more time and effort on routine inspections and repairs, which will increase labor costs. During maintenance and repair, the freight elevator may need to be shut down for a long time, thus affecting the efficiency of cargo transportation and potentially causing economic losses. To solve this problem, the specific operation is as follows: By setting a fixing component, when installing the outer shell 3, first put the outer shell 3 on the first inner plate 2, pull the first mounting rod 16 upward, the second spring 17 is compressed, the first insert block 15 enters the housing 14, so that the connecting block 11 can enter the housing 14. Release the first mounting rod 16, and under the action of the second spring 17, push the first insert block 15 into the first slot 1. In step 3, the first insert 15 is pressed against the top plate of the second insert 21, and then the second mounting rod 19 is pulled to move the second insert 21 out of the housing 14. The third spring 22 is compressed, so the first insert 15 will fully enter the first slot 13, and the second slot 23 and the third slot 24 will be connected. Then the second mounting rod 19 is released, and under the action of the third spring 22, the second insert 21 is pushed back through the second slot 23 and the third slot 24 and pressed against the inner wall of the first slot 13, thereby fixing the housing 3 to the mounting plate 1. The mounting plate 1 can be installed in the designated position with bolts. When it is necessary to maintain the inside of the balance lock, simply pull the second mounting rod 19 and the first mounting rod 16 in sequence to unlock the housing 3 and remove it. It should be noted that the electric push rod 5 is installed in the first inner plate 2. By setting the fixing components and the design of pulling the mounting rod, the disassembly of the balance lock housing 3 becomes simpler and faster. When the balance lock malfunctions, the quick-release housing 3 allows maintenance personnel to quickly inspect the internal components, promptly identify and resolve problems, and reduce the impact of the malfunction on the operation of the freight elevator. This fixed structure can reduce the time spent by maintenance personnel during maintenance and improve work efficiency.

[0033] Reference Figures 1 to 6 In a preferred embodiment, a positioning block 8 is fixedly connected at equal intervals on one side of the mounting plate 1, and the inside of the positioning block 8 is slidably connected to the outside of the outer shell 3; by installing the positioning block 8, the outer shell 3 can be quickly positioned, ensuring stable contact between the fixing components.

[0034] Reference Figures 1 to 6In a preferred embodiment, sealing strips are fixedly connected to one side of both the first inner plate 2 and the second inner plate 4; the use of sealing strips can enhance the integrity of the overall structure, ensure that the electric push rod 5 and the support shaft 6 can operate in a more stable and efficient environment, and ensure that the performance of the balance lock is better.

[0035] Working principle: During use, when installing the outer casing 3, first place the outer casing 3 onto the first inner plate 2, pull the first mounting rod 16 upward, compress the second spring 17, and the first insert 15 enters the casing 14, allowing the connecting block 11 to enter the casing 14. Release the first mounting rod 16, and under the action of the second spring 17, push the first insert 15 into the first slot 13, abutting against the top plate of the second insert 21. Then pull the second mounting rod 19 to move the second insert 21 out of the casing 14, compressing the third spring 22. In this way, the first insert 15 will be fully inserted into the first slot 13, and the second slot 23 and the third slot 21 will be connected. 4. Connect the two parts, then release the second mounting rod 19. Under the action of the third spring 22, the second insert 21 passes through the second slot 23 and the third slot 24 again and abuts against the inner wall of the first slot 13, thereby fixing the outer shell 3 onto the mounting plate 1. The mounting plate 1 can be installed in the designated position with bolts. When it is necessary to maintain the inside of the balance lock, simply pull the second mounting rod 19 and the first mounting rod 16 in sequence to unlock the outer shell 3 and remove it.
