Description

Technical Field

[0001] This utility model relates to the field of gate fixed wheel disassembly and assembly, specifically a gate fixed wheel bearing disassembly device. Background Technology

[0002] A fixed-wheel gate is a planar gate with fixed wheels mounted on its side beams as supporting moving parts. It can withstand large water heads and is widely used in hydropower projects as working gates, emergency gates, and maintenance gates. The planar fixed-wheel gate moves up and down within the gate slot. During operation, the wheels in the fixed-wheel device rotate, generating a reaction force with the cast steel track in the gate slot. This force compresses the side and top water seals on the panel, ensuring the compression of the rubber seals and preventing leakage when the gate is closed. The fixed-wheel device generally includes a wheel frame, axle, self-aligning roller bearings, and wheels.

[0003] When a fixed-wheel gate operates in water, soft debris such as plastic bags and cloth can enter the gate, and debris such as rotten wood and foam can get stuck between the wheel and the cast steel track, causing the wheel to stop rotating and become jammed. This affects the compression of the rubber water seal, and the planar fixed-wheel gate will leak when it is closed. In order to solve the problems existing in the prior art, utility model with announcement number CN218952U discloses a protective device for a planar fixed-wheel gate, including a partition net, brackets connected to both sides of the partition net, and a soft baffle detachably installed on the brackets or the partition net. The partition net is used to cover the top of the fixed-wheel gate, and the soft baffle is used to contact the working surface of the fixed wheel.

[0004] In the prior art 1, a screen and baffle are used to prevent debris from entering the fixed wheel device during operation, ensuring the normal rotation of the wheel. However, since the gate fixed wheel is submerged underwater for a long time and needs to operate frequently under water pressure, even though the screen and baffle in the prior art 1 isolate debris from the water, the bearing of the gate fixed wheel will still experience wear and jamming. The prior art often uses carbon arc gouging to dismantle the fixed wheel bearing, which can easily lead to damage to the fixed wheel bearing and bearing housing. Utility Model Content

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figures 1-4This embodiment discloses a disassembly device for disassembling a fixed wheel bearing installed in a fixed wheel body. Specifically, it is a gate fixed wheel bearing disassembly device, which includes a connecting frame 101 and a driving device 102 installed on the connecting frame 101. The connecting frame 101 is provided with a fixing bolt 103, which is used to cooperate with a threaded hole provided on the fixed wheel body.

[0034] The output end of the drive device 102 is equipped with a plurality of connecting rods 104. A limiting part 105 is rotatably installed at one end of the connecting rod 104 away from the drive device 102. A locking block 106 for cooperating with a stepped groove provided in the fixed wheel bearing is installed at one end of the limiting part 105 away from the connecting rod 104.

[0035] The driving device 102 is used to drive the connecting rod 104 and the locking block 106 to move horizontally.

[0036] In this embodiment, a mounting groove is formed between the inner and outer rings of the fixed wheel bearing, and a stepped groove is provided on the inner and outer rings of the fixed wheel bearing, and the stepped groove communicates with the mounting groove; the fixed wheel bearing is coaxially mounted in the fixed wheel body; the fixing bolts 103 are provided one-to-one with the threaded holes provided on the fixed wheel body; the fixing bolts 103 installed on the connection can cooperate with the threaded holes provided on the fixed wheel body, so that the connecting bracket 101 can be connected to the fixed wheel body without additional processes such as drilling or welding. This reduces equipment modification costs and shortens the construction cycle. Furthermore, the engagement of the threaded hole with the fixing bolt 103 ensures that the output end of the drive device 102 mounted on the connecting frame 101 is aligned with the axis of the fixed wheel bearing, eliminating the need for positioning and installation steps. The existing threaded hole also avoids spatial conflicts in complex structural environments. After the connecting frame 101 is connected to the fixed wheel body via the fixing bolt 103, the drive device 102 drives the connecting rod 104 and the locking block 106 to move towards the fixed wheel bearing until the locking block 104... 6. Enter the mounting slot; at this time, by rotating the limiting part 105, the locking block 106 installed on the limiting part 105 can be rotated. After rotation, the locking block 106, through cooperation with the stepped groove, can limit and fix the fixed wheel bearing, so that when the driving device 102 drives the connecting rod 104 to move the locking block 106, the fixed wheel bearing can be disassembled; in this embodiment, the driving device 102 is a hydraulic jack, and the hydraulic jack can drive the connecting rod 104 to move horizontally along the axis of the hydraulic jack; There are four connecting rods 104, which are equally spaced along the circumference of the output end of the hydraulic jack. This allows the four connecting rods to simultaneously apply tension or thrust to the fixed wheel bearing when the hydraulic jack drives the connecting rods 104 and the locking block 106 to move. This ensures that the fixed wheel bearing can be smoothly disengaged and avoids excessive force on a single point of the fixed wheel bearing, which could lead to bearing deformation, cracking, or journaling. The hydraulic jack, fixed wheel body, and fixed wheel bearing in this embodiment are all conventional devices in the prior art, and their structures and functions will not be described in detail here.

[0037] In some embodiments, a locking mechanism 107 is slidably mounted on the connecting rod 104. The locking mechanism 107 is provided with an engagement groove 108 for limiting and fixing the limiting part 105. The connecting rod 104 is provided with a first stepped platform 109 for limiting the locking mechanism 107. The limiting part 105 is provided with engagement teeth 110 for limiting the locking mechanism 107. When the fixed wheel bearing needs to be disassembled, the locking block 106 is placed into the mounting groove, and the locking mechanism 107 is pulled to separate the engagement groove 108 on the locking mechanism 107 from the engagement teeth 110 on the limiting part 105, thus no longer fixing the limiting part 105; then, by rotating the limiting part 105, the locking block 106 installed on the limiting part 105 is rotated into the stepped groove; after the stepped groove and the locking block 106 cooperate to limit the connecting rod 104, the locking mechanism 107 is moved so that the engagement groove 108 on the locking mechanism 107 and the engagement teeth 110 on the limiting part 105 cooperate again, thus fixing the locking block 106 in the stepped groove, preventing the locking block 106 from dislodging from the stepped groove during the movement of the fixed wheel bearing caused by the displacement of the locking block 106.

[0038] In some embodiments, a slider 111 is provided on the connecting rod 104, and a groove is provided on the locking mechanism 107 for sliding engagement with the slider 111. The groove is used to limit and guide the slider 111 and the locking mechanism 107; when the locking mechanism 107 is slidably connected to the slider 111 through the groove, the locking mechanism 107 moves vertically along the slider 111, and the slider 111 limits the locking mechanism 107 to prevent it from rotating.

[0039] In some embodiments, the locking mechanism 107 includes a locking member 112 and a spring 113, the engagement groove 108 is disposed on the locking member 112, and the first step 109 is connected to the locking member 112 via the spring 113. In this embodiment, the engagement groove 108 is provided on the locking member 112, and the pull ring is fixedly connected to the locking member 112. After the locking block 106 is placed into the installation groove, the locking member 112 is pulled away from the limiting part 105, causing the engagement groove 108 on the locking member 112 to separate from the engagement teeth 110 on the limiting part 105, thus no longer fixing the limiting part 105. At this time, the spring 113 is compressed. After rotating the locking block 106 to engage with the stepped groove, the locking member 112 is released, causing the locking member 112 to move towards the limiting part 105 under the force of the spring 113. The engagement groove 108 on the locking member 112 and the engagement teeth 110 on the limiting part 105 engage again, thus locking the limiting part 105.

[0040] In some embodiments, the mounting plate of the drive device 102 is provided with an adjustment groove 114, and the connecting rod 104 is detachably installed in the adjustment groove 114. In this embodiment, the connecting rod 104 is provided with a second stepped platform, and the connecting rod 104 is slidably installed in the adjustment groove 114 and detachably connected to the adjustment groove 114 by a fixing nut 116. In actual use, the fixed wheel bearings of different sizes can be disassembled by adjusting the position of the connecting rod 104 in the adjustment groove 114, and the connecting rod 104 adjusted to a suitable position can be fixed by the cooperation of the fixing nut 116 and the second stepped platform.

[0041] In some embodiments, the locking block 106 is detachably connected to the limiting part 105. The locking block 106 is fixedly connected to a stud, and the locking block 106 is threadedly connected to the limiting part 105 through the stud. Depending on the size of the slot on the fixed wheel bearing that needs to be disassembled, different sizes and shapes of locking blocks 106 can be replaced to further improve the disassembly efficiency and disassembly effect of the fixed wheel bearing.

[0042] In some embodiments, the locking block 106 is provided with a locking groove 115. The locking groove 115 is used to cooperate with the stepped groove. By providing the locking groove 115, the contact area between the locking block 106 and the stepped groove can be increased, thereby further limiting the fixed wheel bearing and improving the disassembly efficiency and disassembly effect of the fixed wheel bearing.

[0043] In some embodiments, a support frame is rotatably hinged to one end of the connecting frame 101 away from the locking block 106. In this embodiment, the support frame is rotatably connected to the connecting frame 101 via a rotating shaft. After the connecting frame 101 is mounted on the fixed wheel body by fixing bolts 103, rotating the support frame allows it to contact the ground and further support the connecting frame 101, significantly improving the overall load-bearing capacity of the connecting frame 101. This avoids the fixing bolts 103 and the threaded hole from bearing all the disassembly force alone, which could cause the threaded hole on the fixed wheel body to be damaged due to overload.

[0044] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
