Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder positioning brackets, and in particular to an emergency door hydraulic cylinder disassembly and positioning bracket. Background Technology

[0002] In large-scale water conservancy facilities such as water conservancy projects and hydropower hubs, emergency exit gates are key equipment for ensuring the safe operation of the project. They are commonly used to quickly close passages in the event of emergencies (such as pipeline ruptures or equipment failures) to prevent water loss and significant losses. The opening and closing of emergency exit gates mainly relies on hydraulic cylinders, and their operating status directly affects the gate's response speed and reliability. Therefore, when hydraulic cylinders experience malfunctions such as leakage, abnormal noise, or insufficient thrust, they must be disassembled, repaired, or replaced promptly.

[0003] However, emergency door hydraulic cylinders are usually large and heavy (some large hydraulic cylinders can weigh several tons), and are often installed in damp, space-constrained hoisting rooms or corridors. During disassembly, they face problems such as difficult positioning, high operational risks, and poor compatibility of auxiliary tools. In traditional hydraulic cylinder disassembly operations, the positioning process lacks specialized equipment, often relying on simple supports combined with tools such as hoists and jacks for temporary fixation. Because the hydraulic cylinder body is cylindrical, it is prone to rolling during placement, making it difficult for existing positioning methods to achieve precise and stable positioning. On the one hand, unstable positioning can cause the hydraulic cylinder to shift or tip over during disassembly, affecting disassembly efficiency and potentially leading to equipment damage or personal injury. On the other hand, traditional positioning structures cannot apply stable pressure from directly above, making it difficult to guarantee the axial stability of the hydraulic cylinder when removing bolts or separating connecting parts, and easily causing component deformation due to uneven stress. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a positioning bracket for disassembling hydraulic cylinders of emergency doors, which can achieve precise and stable positioning of the hydraulic cylinder body and ensure safety and stability during hydraulic cylinder disassembly operations.

[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 and positioning bracket includes a base, on which disassembly and assembly mechanisms are arranged at intervals on the left and right sides. A lower positioning pad is placed on the base and fixed by the disassembly and assembly mechanisms. The lower positioning pad is connected to the upper positioning pad and forms a limiting ring that clamps the emergency door hydraulic cylinder. A pressing mechanism is installed on the upper positioning pad and presses the emergency door hydraulic cylinder.

[0006] The base includes a top plate, and a support rod is fixed to the bottom of the top plate at an angle to the left and right. The bottom of the support rod is fixedly connected to a base.

[0007] A reinforcing rod is fixedly connected between the two bases.

[0008] A counterweight is attached to the reinforcing rod.

[0009] The counterweight has a slot on one side, and the counterweight is engaged with the reinforcing rod through the slot.

[0010] The disassembly and assembly mechanism includes a hydraulic rod, which is fixed to a vertical plate, and the vertical plate is fixed to a top plate. A connecting plate is fixed to the output end of the hydraulic rod, and a positioning block is fixed to the lower end of the connecting plate. The positioning block engages with or disengages from the slot of the fixing block.

[0011] The pressing mechanism includes an electric push rod fixed on the upper positioning pad, and an arc-shaped pad is fixedly connected to the output end of the electric push rod.

[0012] The curved pad is concentric with the upper positioning pad and is made of silicone.

[0013] The electric linear actuator is electrically connected to a battery, which is mounted on the surface of the electric linear actuator.

[0014] The base is made of stainless steel.

[0015] This utility model provides a hydraulic cylinder disassembly and positioning bracket for emergency doors, which has the following technical advantages: 1) By setting up a pressing mechanism, during use, the electric push rod presses the arc-shaped silicone pad against the side wall of the emergency door hydraulic cylinder, pressing down and fixing the emergency door hydraulic cylinder, which improves the stability of the emergency door hydraulic cylinder during disassembly and assembly; at the same time, for emergency door hydraulic cylinders within a certain diameter range, the pressing mechanism can achieve clamping, improving versatility.

[0016] 2) With the installation and disassembly mechanism, the lower positioning pad is placed on the top plate and fixed by snapping the top plate with the positioning blocks of the installation and disassembly mechanism. This eliminates the need for bolts and only requires snapping to install the lower positioning pad, thus improving the installation efficiency of the installers.

[0017] 3) The base of this device consists of a top plate, support rods, base, reinforcing rods, and counterweights, all made of I-beams to ensure strength and rigidity. Even when facing large emergency door hydraulic cylinders, it can maintain stability and its own structure will not deform. Attached Figure Description

[0023] like Figure 1 As shown, an emergency door hydraulic cylinder disassembly and positioning bracket includes a base 14, with a lower positioning pad 1 arranged on the upper end of the base 14. Fixing blocks 2 are fixed on both the left and right sides of the lower end of the lower positioning pad 1. The upper surface of the fixing blocks 2 is provided with a slot. Disassembly and assembly mechanisms 3 are installed on the base 14 on the left and right sides of the lower positioning pad 1. The disassembly and assembly mechanisms 3 can engage or disengage with the fixing blocks 2, thereby quickly completing the installation and disassembly of the lower positioning pad 1 without the need for bolt installation, thus improving the installation efficiency of the installers.

[0024] The upper positioning pad 4 is hinged to one edge of the top surface of the lower positioning pad 1 via a hinge. The other side of the upper positioning pad 4 is threaded with a bolt. When the upper positioning pad 4 and the lower positioning pad 1 are aligned and assembled, the bolt is screwed into the threaded hole of the lower positioning pad 1, thereby closing the upper positioning pad 4 and the lower positioning pad 1 and clamping the hydraulic cylinder of the emergency door.

[0025] The upper positioning pad 4 is equipped with a pressing mechanism 5, which presses down and fixes the hydraulic cylinder, improving the stability of the hydraulic cylinder during disassembly and assembly.

[0026] like Figures 2-3 As shown, specifically, the base 14 includes a top plate 6, which is located at the bottom of the lower positioning pad 1. Vertical plates 7 are fixedly connected to the upper ends of both the left and right sides of the top plate 6. Two support rods 9 are fixedly connected to the bottom of the top plate 6, and a base 10 is fixedly connected to the bottom of each support rod 9. The support rods 9 serve to support the top plate 6.

[0027] A reinforcing rod 11 is fixedly connected between the middle of the two bases 10. The reinforcing rod 11 is made of stainless steel. The reinforcing rod 11 increases the structural strength of the base 10.

[0028] A counterweight 12 is attached to the middle of the reinforcing rod 11. A slot is provided on one side of the counterweight 12. The counterweight 12 increases the stability of the base 10.

[0029] like Figure 3As shown, the disassembly and assembly mechanism 3 includes a hydraulic rod 303, which is fixedly connected to the surface of the upright plate 7. The upright plate 7 serves to support the hydraulic rod 303. A connecting plate 302 is fixed to the output end of the hydraulic rod 303, and a positioning block 301 is fixed to the lower end of the connecting plate 302. The positioning block 301 can be inserted into the slot of the fixing block 2.

[0030] like Figure 4 As shown, the pressing mechanism 5 includes an electric push rod 501 fixedly connected to the surface of the upper positioning pad 4. The output end of the electric push rod 501 extends radially out of the inner wall of the upper positioning pad 4 and points towards the central axis of the upper positioning pad 4. An arc-shaped pad 502 is fixedly connected to the output end of the electric push rod 501.

[0031] like Figure 4 As shown, preferably, a battery 8 is electrically connected to one side of the electric push rod 501 via a power cord. The battery 8 is installed on the surface of the electric push rod 501, and the battery 8 provides continuous power supply.

[0032] like Figure 2 As shown, preferably, the surface of the base 10 is provided with a threaded hole, and the internal thread of the threaded hole is connected to a positioning bolt 13. The positioning bolt 13 serves to fix the base 10 to the ground or related equipment.

[0033] Working principle and process: 1) The lower positioning pad 1 overlaps the top plate 6, so that the fixing blocks 2 on both sides of the lower positioning pad 1 are located directly below the connecting plate 302, and the slots opened on the fixing blocks 2 are directly opposite the positioning block 301 at the bottom of the connecting plate 302. At this time, the top hydraulic rod 303 (small hydraulic cylinder) is activated, and the hydraulic rod 303 drives the bottom connecting plate 302 to move until the positioning block 301 at the bottom of the connecting plate 302 is inserted into the slot on the surface of the fixing block 2.

[0034] 2) When using this device, place the hydraulic cylinder on the lower positioning pad 1, then rotate the upper positioning pad 4 at the top, and fix the upper positioning pad 4 and the lower positioning pad 1 with bolts. Finally, turn on the power and start the electric push rod 501 on the upper positioning pad 4. The electric push rod 501 drives the end arc-shaped pad 502 to move until the arc-shaped pad 502 can be tightly attached to the top of the hydraulic cylinder.
